A top cover (bonnet cover) that covers the top of the elements (motor, etc.) mounted on the base is generally attached to the upper part of the body of the Vibro compactor (international). Published WO2014 / 155492 etc.). It should be noted that large and medium-sized vibro compactors are usually configured to cover the entire upper part of the airframe with a sturdy top cover with high rigidity, while small vibro compactors are lightweight and lightweight. One of the features is that it is easy to handle, so a lightweight and relatively simple structure is often used as the top cover.

Specifically, if a thick metal plate is used as the constituent material for the top cover of a small vibro compactor, and the structure is such that the entire upper part of the aircraft is covered with this metal cover, the weight will be unnecessarily heavy. In addition, the original characteristic of "small size and light weight" will be impaired. For this reason, in a small vibro compactor, the top of the structure is such that the upper surface of the airframe is partially covered with a thin metal plate (the elements on the base that selectively cover only important elements such as the prime mover). Covers are often used.

However, the structure of the top cover as described above in a small vibro compactor is required to be improved from the viewpoint of durability and the like. More specifically, in order to improve the durability of the entire aircraft and avoid defects and troubles as much as possible, it is necessary to protect all the elements on the base more effectively, and at the same time. It is necessary to ensure accessibility and ease of handling of the elements on the base. Then, it is necessary to realize such an improvement without impairing the original characteristics of the small vibro compactor, which is "small and lightweight".

The present invention seeks to solve such problems in the prior art, can effectively protect all elements on the base, and has accessibility and ease of handling to the elements on the base. It is an object of the present invention to provide a vibration compactor that can be expected to be significantly improved.

The vibration compactor according to the present invention has a compaction plate equipped with a vibration exciter, a base supported above the compactor, a prime mover mounted on the base, and a guide fixed so as to surround the elements on the base. It has a frame, a top cover attached to the top of the guide frame so as to cover above the elements on the base, and a handle for operating the aircraft, which opens the front half of the top of the guide frame. It is composed of a front top cover configured to allow the front top cover and a rear top cover configured to open the upper rear part of the guide frame, and the front top cover and the rear top cover are partially closed. It is characterized in that it is configured so as to overlap vertically.

The rear top cover is preferably made of a flexible material, and it is preferable that a vibration-proof material is arranged at a hinge portion which is a fulcrum of rotation of the front top cover. Further, it is preferable that the front end side portion of the rear top cover is overlapped on the rear end side portion of the front top cover, and the access opening is formed in the rear end side portion of the front top cover.

In addition, slits are formed in the rear end side portion of the front top cover and the front end side portion of the rear top cover, and these slits are positioned so as to overlap vertically and are arranged above the instruments. The hook locking portion is fixed to the upper part of the guide frame, and the rear top cover is configured to be able to pass through a narrow region on the lower side of the hook locking portion by bending or bending. Is preferable.

In the vibration compaction machine according to the present invention, the top cover has a front top cover configured to open the upper front half of the guide frame and a rear configured to open the upper rear half of the guide frame. By configuring with a top cover, all the elements on the base can be effectively protected, and the accessibility and ease of handling of the elements on the base can be expected to be greatly improved.

Furthermore, when the top cover is closed, the front top cover and the rear top cover are configured to partially overlap each other, so that the vibration compactor is operated or the machine is impacted.

Hereinafter, embodiments of the present invention "vibration compaction machine" will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing the appearance of the vibration compaction machine 1 according to the present invention. The vibration compaction machine 1 includes a compaction plate 2 equipped with a vibration exciter, a base 3 supported above the compactor plate 2, a prime mover mounted on the base 3 (internal combustion engine engine in the present embodiment), and a compaction machine 1. It has a handle 4 and the like for operating the machine body, and is configured so that the driving force is transmitted from the prime mover to the vibration exciter and the compaction plate 2 vibrates so that the ground and the like can be compacted.

In the vibration compaction machine 1 of the present embodiment, the vibrating device has a biaxial eccentric pendulum and can change the rotation phase of one eccentric pendulum (phase with respect to the other eccentric pendulum). It is a "vibro compactor" that is configured so that the aircraft can be moved forward or backward by a synthetic vector of biaxial eccentric pendulums.

In this vibration compaction machine 1, in order to protect the elements on the base 3 (motor, fuel tank, air cleaner, etc.), a guide frame 5 formed by a metal pipe is fixed so as to surround those elements. .. Further, a hook locking portion 6 for locking the hook of the crane is fixed to the upper part of the guide frame 5 when the machine body is suspended by a crane (truck-mounted crane or the like). Further, a top cover 7 is attached to the upper part of the guide frame 5 so as to cover the upper part of the elements on the base 3 in order to protect the elements.

The top cover 7 is composed of a front top cover 7A and a rear top cover 7B, which cover most of the upper part of the guide frame 5 (90% or more of the area of the upper part of the guide frame 5). You can do it. The front top cover 7A is made of hard plastic, and the rear top cover 7B is made of a flexible material (rubber plate in this embodiment). Further, the front top cover 7A and the rear top cover 7B are both configured to be openable and closable so that the upper portion of the guide frame 5 can be greatly opened.

Specifically, as shown in FIG. 2, the front top cover 7A is configured to be rotatable about a position on the front side of the guide frame 5 (in this embodiment, a position of the upper front end) as a fulcrum. By lifting the rear end side diagonally upward from the state shown in FIG. 1, the front half of the upper part of the guide frame 5 can be opened as shown in FIG. .. A vibration-proof material 9 (vibration-proof rubber or the like) is arranged on the hinge portion 8 which is a fulcrum for the rotation of the front top cover 7A, and vibration transmitted to the front top cover 7A via the guide frame 5. Can be effectively attenuated.

On the other hand, in the rear top cover 7B, the rear end edge 10 (see FIG. 1) is fixed at the rear end position of the upper part of the guide frame 5, and the portion other than the rear end edge 10 can be elastically deformed. By rolling up the front end side diagonally upward on the rear side of the machine body, the latter half of the upper part of the guide frame 5 can be opened as shown in FIG.

Further, the front top cover 7A and the rear top cover 7B are configured to partially overlap each other in the closed state. More specifically, as shown in FIG. 3, the dimensions are set so that the front end side portion 12 of the rear top cover 7B can be overlapped on the rear end side portion 11 of the front top cover 7A, and the rear top is set. The front top cover 7A is stably pressed by the elastic force and weight of the cover 7B, the closed state of the front top cover 7A is maintained when the vibration compaction machine 1 is operating or moved, and the machine body is impacted. Even when (or other external force) is received, it is possible to suitably avoid a situation in which the front top cover 7A jumps up or rampages, and generation of noise due to rattling. Therefore, it is not necessary to arrange a lock mechanism (buckle or the like) for maintaining the closed state of the front top cover 7A, and the configuration can be simple.

Further, an access opening 13 is formed in the rear end side portion 11 of the front end cover 7A on which the front end side portion 12 of the rear top cover 7B is overlapped, and the rear top cover 7A is closed. When the front end side portion 12 of 7B is rolled up, the access opening 13 is exposed, and the element below the access opening 13 from above the aircraft via the access opening 13 (in the present embodiment, the fuel tank cap shown in FIG. 2). 14) can be accessed, and the fuel tank can be refueled with the front top cover 7A closed.

Further, a slit 15 (viewing window) is formed in the rear end side portion 11 of the front top cover 7A, and the corresponding positions (front top cover 7A and rear top cover 7B) in the front end side portion 12 of the rear top cover 7B are formed. Slits 16 (see FIG. 2) are also formed at positions that overlap each other when the window is closed. These slits 15 and 16 are arranged above the instruments (in this embodiment, the fuel tank fuel gauge), and the fuel is maintained with the front top cover 7A and the rear top cover 7B closed. You can check the remaining amount of the tank.

As shown in FIGS. 1 and 2, a hook locking portion 6 for suspending the machine body is fixed to the upper part of the guide frame 5. This type of hook locking part equipped on a general vibro compactor is located above the center of gravity of the airframe so that the airframe does not tilt when the airframe is suspended by a crane. If such a hook locking portion is present at an upper position of the top cover, it may interfere with the opening and closing of the top cover, and it may be difficult to configure the top cover so that it can be opened and closed.

In the present embodiment, as shown in FIG. 4, the front top cover 7A has dimensions and configurations that do not interfere with the hook locking portion 6 when opening and closing, and the rear top cover 7B is made of a flexible material. As shown in FIG. 4, it is possible to pass through a narrow region on the lower side of the hook locking portion 6 by appropriately bending or bending the hook. Therefore, in the vibration compaction machine 1 of the present embodiment, the front top cover 7A and the rear top cover 7B can be opened and closed without any problem even though the hook locking portion 6 is arranged at the upper position of the guide frame 5. As shown in FIG. 2, the upper part of the guide frame 5 can be greatly opened, and accessibility and ease of handling to each element (motor, gasoline tank, air cleaner, etc.) mounted on the base 3 can be achieved. You can expect a significant improvement in gasoline.

Although the embodiment in which the top cover 7 having a characteristic structure is applied to the vibro compactor has been described here, the application target is not limited to the vibro compactor, and the top cover 7 can be applied to the plate compactor. Further, in the above embodiment, the internal combustion engine engine is adopted as the prime mover mounted on the base 3, but a battery-powered electric motor can also be mounted. In this case, the battery can be easily replaced by opening the upper part of the guide frame 5 to a large extent. That is, the structure of the top cover 7 in the present invention can be shared regardless of the type of the prime mover to be mounted.
