Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a snow removal device that scoops up, transports, and removes snow that has fallen on roads, etc. in snowy areas.

[Prior Art] As shown in FIG. 1, a wide bucket 10 with a sled-like lower surface is used as a device or tool to remove snow that has fallen on roads, etc. in snowy areas. A snow blower A, so-called Mama-san dump, which has a handle 11 shaped like a toy for pushing it out, is attached to the rear end, and a second snow blower
As shown in the figure, crawlers 20, 20 on the left and right
A bucket 30 formed in a wide width is attached to the upper surface of a traveling crawler type vehicle body 2 equipped with an engine e for driving the crawlers 20, 20 and control handles 21, 21 on the rear end side. A walk-behind transport vehicle B is mounted so that the dump truck can be rotated manually by lifting the engine 31, and as shown in FIG. A walk-behind snow blower C is provided with a raking wheel 42 driven by the engine e and a guide plate 43 on the front end of a walk-behind vehicle body 4 having a handle 41; As shown, the engine is installed at the front end of a walking-type crawler-type vehicle body 5, which is equipped with left and right crawlers 50, 50 (one of which is not clearly shown in the drawing), an engine e for driving the crawlers, and a control handle 51. Snow blower D is equipped with screw augers 52, 52 which are driven by e and which transport the snow laterally, and a blow up blower 53 which blows up the snow that has been raked up by the screw augers, and is also disclosed in Japanese Utility Model Application Publication No. 14832/1983. In this way, a shovel supporting bracket protruding from the front side is provided on the work machine body which is driven by a crawler, and the shovel is attached to the middle part of the front and rear so that the front end faces below the ground plane of the crawler. A work machine with a shovel, etc., in which the shovel is pivoted and the shovel rotates forward around the pivot axis by unlocking the shovel and the work machine body and moving the work machine forward. It has been known and used for a long time.

These conventional snow dumpers A have a simple structure, can load, transport, and discharge snow with one unit, and are inexpensive.
Although it has the advantage of being easy to use, it causes severe fatigue because workers have to push it by hand, and it also has poor workability when climbing snowy slopes to remove snow, resulting in frequent falls and injuries. .

In addition, the amount of snow that can be transported by the transport vehicle B at one time is much larger than that of the snow dumper A mentioned above, and the dump truck 30 must be rotated manually to discharge the snow at the location where it is transported. Although there is an advantage that it can be done easily with a bucket, the task of loading snow into a bucket
It must be done manually using a scoop,
Moreover, the price is about 80 yen compared to the snow dump A.
The problem is that it is twice as expensive.

In addition, snow blower C and snow blower D can remove snow without the need for snow loading, but since the snow can be blown away at a distance of up to 10 meters, it is difficult to transport the snow to a designated location and discharge it. There is a problem that it is difficult to remove snow from a specified narrow place, and the price is about 100 times more expensive than the snow dumper A.

In addition, in the case of a work machine with a shovel, by moving the work machine forward while the front end of the shovel is in contact with the ground, the shovel with its front end stuck can be pushed forward and the dumper rotated. Therefore, if slippage occurs at the front end, the dumping rotation will not be performed, resulting in the problem that the dumping rotation of the excavator is uncertain.

The present invention was developed to solve these problems that have arisen with conventional means, and allows the series of tasks of loading, transporting, and discharging snow to be carried out easily.
Moreover, it is an object of the present invention to provide a snow remover at a low cost, in which the dumping rotation of the bucket for discharging snow is reliably performed.

In the present invention, as a means to achieve this purpose, a lever rod is formed that has a U-shape in plan view and is bent at a shallow upward angle toward the rear end from a portion slightly closer to the rear end than the front end in side view. A handle main body is shaped like a handle, and a bucket main body has a sled-shaped bottom surface, and the left and right front ends of the handle main body and the left and right sides near the rear end of the bucket main body are rotatably connected by a connecting shaft. During assembly, a locking mechanism is provided between the handle main body and the bucket main body to hold the handle main body, which rotates relative to the bucket cart main body, at a desired rotational position about the connection shaft, and the handle main body includes: A support rod that runs along the rear wall surface of the bucket main body is installed near the bent portion in a side view, and a power unit consisting of a speed reducer, an engine, running wheels, etc. can be freely centered on the support rod. The present invention proposes a snow blower that is assembled via a mounting frame so that it can rotate.

By screwing the set bolt into the assembly seat provided on the bottom side of the power unit 8, the power unit 8 can be attached to surround the bottom side of the power unit 8. The rear end side of this sled body 9 is formed into a tape shape as shown in FIG. 10, and when the power unit 8 is assembled and set in the raised position relative to the bucket body 6 This loop-shaped portion constitutes a grip portion 91 for pulling the snow blower W backward.

Next, FIG. 11 shows another embodiment. In this embodiment, when the front end of the bucket main body 6 is pulled by a wire b by operating a lever a provided on a handle rod 70, the front end of the bucket main body 6 is rotated upward about a support shaft c, and the front end of the bucket main body 6 is dammed. The only difference from the previous embodiment is that an auxiliary leading edge d that serves as a weir plate is provided, but the basic configuration remains the same.For the rest of the configuration, the same reference numerals are given to the same components and detailed explanations are given. Explanation will be omitted.

The embodiment device constructed in this manner operates as follows.

To release fallen snow or snow S that has been shoveled up, first operate the operating lever 77 to rotate the latch 72 backwards to release the lock, part side) downwards. As a result, the handle main body 7a rotates counterclockwise in FIG. 12 about the support rod 74, which is supported by the power unit 8 on which the running wheel 83 is in contact with the ground, as a fulcrum P. Then, the front end connected to the connecting shaft 78 rises, and the rear end side of the bucket bag main body 6 which is pivotally supported via the connecting shaft 78 is lifted up, so that the bucket bag main body 6 is placed in a posture with the front end side lowered. When this state is reached, the operation lever 77 is released and the latch 72 is engaged with the latch pawl 62, thereby locking it in the state shown in FIG. 12. In this state, the power unit 8 is driven to advance. As a result, the snow to be removed is dredged and loaded into the bucket main body 6.

As a result, when a predetermined amount of snow S has been loaded, the latch 72 is unlocked by operating the operating lever 77 again, and the proximal side of the handle main body 7a is rotated upward about the fulcrum P. The rear end of the bucket main body 6 is in contact with the ground and the front end is slightly raised.
to lock into the state shown in FIG. 13.
In this state, the power unit 8 is driven to move it forward. As a result, the bucket main body 6 becomes a sled, and by driving the running wheels 83, 83, as shown in FIG. 14, it can easily climb even a slight slope and travel to a desired location for transportation. During this transportation work, in the embodiment shown in Fig. 11, by keeping the auxiliary leading edge d in an upright position as shown in Fig. 15, the loaded snow is prevented from spilling forward. I come to do it.

When the user comes to a place where the snow should be removed during this transportation, the latch 72 is released again and the proximal side of the handle body 7a is pushed down significantly. As a result, the handle main body 7a acts as a lever that rotates around the fulcrum P consisting of the support rod 74 supported by the power unit 8, and as shown in FIG. As the end side is lifted up, the dumper rotates to release the snow loaded in the bucket main body 6.
The snow that has been transported will be removed.

If the place where snow is to be removed is under a cliff or plateau, as shown in FIG. The dumper automatically rotates around the connecting shaft 78 to remove the snow that has been transported.

Next, FIG. 18 is an explanatory diagram of the backward movement operation when the power unit 8 is not equipped with a reversing mechanism and therefore cannot drive the running wheels 83 in reverse rotation. In the released state, the bucket main body 6 side is grounded,
The handle main body 7a is rotated upward around the connecting shaft 78 so as to raise the power unit 8 together, and is locked in the state shown in FIG. 18, thereby grasping the sled body 9 of the power unit 8 occupying the raised position. Pull it backward as a part.

[Effects of the invention] As explained above, the snow blower W according to the invention has the following advantages:
A bucket main body having a lever-shaped handle main body 7a which is U-shaped in plan view and bent at a shallow upward angle from a portion slightly closer to the rear end than the front end to the rear end in side view, and the bottom surface is formed into a sled shape. 6, the left and right front ends of the handle main body 7a and the left and right sides near the rear end of the bucket main body 6 are rotatably connected and assembled by connecting shafts 78, 78, and the handle main body 7a and the bucket main body 6 are assembled. A lock mechanism L is provided between the main body 6 and the handle main body 7a, which holds the handle main body 7a, which rotates relative to the bucket main body 6, at a desired rotational position about the connecting shafts 78, 78, and the handle main body 7a has the following features: A support rod 74 along the rear wall surface of the bucket main body 6 is installed near the bent portion in a side view, and a power unit consisting of a reducer 81, an engine 80, running wheels 83, 83, etc. is mounted on the support rod 74. 8 is assembled via the mounting frame 73 so that it can freely rotate about the support rod 74, so when the lock mechanism L is released, ), the handle main body 7a becomes supported by the power unit 8 which is held on the ground by the grounding of the running wheels 83. Using the support rod 74 as a fulcrum P, the handle main body 7a becomes a lever that raises the front end. As a result, the rear end of the bucket main body 6, which is connected to the front end of the handle main body 7a via the connecting shaft 78, is lifted up, and the snow loaded in the bucket main body 6 is released. The operation of dumping and rotating the bucket main body 6 is performed using the handle main body 7.
This can be done easily and reliably by leveraging a. Furthermore, due to the rotation of the handle main body 7a about the fulcrum P, the handle main body 7a rotates about the connecting shaft 78 relative to the bucket main body 6, so that the rotation angle of the handle main body 7a with respect to the bucket main body 6 is By locking the bucket at a desired angle with the locking mechanism L, the bucket main body 6 can be switched between a state in which the front end side floats up and touches the ground through the sled-shaped bottom surface, and a state in which the front end side touches the ground and dredges up snow. As a result, the work of digging up snow and transporting the dug-in snow can be done easily and efficiently. Therefore, the bucket main body 6 can be easily rotated manually, and a snow blower with good workability that can easily carry out all the tasks of loading, transporting, and removing snow can be obtained at a low cost.
