Description

Ditch dredging machine

The invention relates to dredging engineering, in particular to a ditch dredger that can automatically move in a ditch to remove deposits such as silt or garbage.

Press, in recent years, due to the poor drainage of the gutter, the gutter cannot play a drainage role when it rains heavily, and it is not uncommon to cause local flooding. Ordinary people questioned whether it was caused by poor design of the ditch and asked for it to be rebuilt. However, after field surveys, it was found that most of the ditches have poor drainage, mainly because they are blocked by silt or garbage, which makes the drainage function unable to perform. Therefore, regular cleaning of garbage and silt in the ditch has become the primary countermeasure to prevent flooding.

Since ditch dredging mostly relies on manpower or machinery to extract sludge and sundries, such as large machines such as ditch cleaning trucks or dredging machines. However, most of the mechanical devices are only suitable for medium and large ditches, and the small ditches beside the road are often ignored. Small ditches are shallower, more prone to clogging than large ditches, and cannot be entered by machines. Therefore, the dredging of small ditches is usually done by manpower. The dredging work often needs to invest a lot of manpower and time, which is a burden for manpower cost or time cost. Therefore, the industry has begun to develop more convenient dredging devices for small ditches.

Wherein, Taiwan's No. M619075 new patent discloses a ditch garbage cleaning machine, which includes a vibrating motor, a body, a rake and a collection net.

The problem with the above-mentioned ditch cleaning machine is that the moving direction formed by the vibrating motor is not fixed, so it is still necessary to rely on a worker to control the moving direction of the machine body through a rope, which does not reduce the manpower requirement; in addition, the efficiency of collecting garbage through the rake and the collection net is too low to effectively save the time for cleaning the ditch. Therefore, how to effectively collect and remove the silt and garbage in the drainage ditch, and achieve the effect of saving labor costs and time costs, is one of the tasks that researchers in related fields need to complete urgently.

In this embodiment, the communication module 54 is a wireless transmission method; in another embodiment, the communication module 54 may be a wired transmission method.

According to the above structural configuration, the actual operation and application of the ditch dredging machine 1 provided by the present invention is as follows: Please refer to FIG. 5, the ditch dredging machine 1 can be installed in the ditch 2 to perform dredging tasks, and automatically move in the ditch by the moving device 20. When the ditch dredger 1 moves, with the help of the guide wheels 190, the main body 10 moves toward the wall of the ditch 2, a part of the guide wheels 190 contacts the wall of the ditch 2 earlier than the main body 10, and the rotation of the guide wheels 190 can guide the ditch dredger 1 to turn, thereby ensuring that the main body 10 will not stop moving due to bumping into the wall of the ditch 2. At the same time, at least one accumulation 3 located on the moving path of the ditch dredging machine 1 will be scooped up by the blade 18 and enter the collection area 16 from the inlet 160 of the main body 10 . Then, if the volume of the deposit 3 exceeds a certain size, it will contact the crushing device 30 located in the collection area 16.

Next, the conveying device 40 The conveyer belt 42 will carry the piled debris 4, and transport it from the first end 421 to the second end 422, and finally fall into the storage box 170 of the storage area 17 for storage, completing the operation of automatically removing the accumulation.

During the task execution of the ditch dredger 1, the sensors 531, 532, 533, 534, 535, 536, 537, 538 of the detection module 53 will also operate synchronously, and automatically control the ditch dredger 1 through the processor 51 to confirm whether the working environment and working conditions of the ditch dredger 1 need to be adjusted. The function of each of the sensors 531, 532, 533, 534, 535, 536, 537, 538 will be described one by one below: the water level sensor 531 detects the height of the water level in the gutter 2 through ultrasonic waves, and generates the water level signal accordingly to the processor 51 for judgment by the processor 51. If the processor 51 judges through the water level signal that the water level in the ditch 2 exceeds a water level limit value, the processor 51 sends a water level warning signal through the communication module 54 to notify the staff to come and recover the ditch dredger 1 to prevent it from being damaged or lost.

The flow velocity sensor 532 is used to detect the flow velocity of the water in the gutter 2, so as to generate the flow velocity signal to the processor 51. After judging the flow velocity in the gutter 2 by the flow velocity signal, the processor 51 automatically adjusts the operating speeds of the mobile device 20, the crushing device 30 and the conveying device 40 accordingly, so as to optimize cleaning efficiency and reduce power consumption.

The position sensor 533 detects the position of the ditch dredger 1 in the ditch 2 through GPS positioning, and generates the position signal to the processor 51, and the processor 51 transmits it to the remote device through the communication module 54, so that the staff can grasp the real-time position of the ditch dredger 1 at any time to prevent it from being lost. On the other hand, the worker can also control the moving path of the ditch dredging machine 1 through the remote device.

The balance sensor 534 is used to detect that the main body 10 is in a balanced state or a tilted state, so as to generate the balance signal to the processor 51 . If the processor 51 judges that the main body 10 is Now, if it is in a tilted state, the communication module 54 is used to notify the staff to come and reclaim the ditch dredging machine 1 to prevent it from being damaged or lost.

The storage capacity sensor 535 is used to detect the storage capacity of the accumulation in the storage area 17, so as to generate the storage capacity signal to the processor 51. If the processor 51 determines through the storage capacity signal that the storage capacity of the storage area 17 exceeds a storage capacity limit value, the processor 51 sends a full load alarm to the remote device through the communication module 54, notifying the staff to come and remove the accumulation in the storage area 17. In this embodiment, the storage capacity sensor 535 detects the height of the accumulation in the storage area 17 to determine the storage capacity; in another embodiment, the storage capacity sensor 535 can detect the weight of the accumulation in the storage area to determine the storage capacity.

The width sensor 536 is used to detect the width of the gutter located in front of the main body 10 , so as to generate the width signal to the processor 51 . If the processor 51 judges through the width signal that the width of the ditch 2 is not enough to allow the main body 10 to pass through, the processor 51 automatically controls the mobile device 20 to stop the main body 10, and notifies the staff through the communication module 54 to go to the scene to recover the ditch dredging machine 1.

The biological sensor 537 detects objects on the moving path through infrared rays, and generates the biological signal to the processor 51 if there is biological invasion. If the processor 51 automatically determines biological invasion through the biological signal, it can link the camera 538 for further confirmation.

The camera 538 is used to capture the real-time image near the ditch dredging machine 1, transmit the real-time image to the processor 51, and transmit it to the remote device in real time through the communication module 54, so that the staff can judge the current working condition or working location of the ditch dredging machine 1 accordingly. On the other hand, in order to prevent the biological sensor 537 from misjudging the biological invasion, the staff can rely on the real-time image captured by the camera 538 to make further judgments, and if it is determined that there is a living creature, then control the mobile device 20 to stop the movement of the main body 10, so as to avoid biological involvement in the ditch dredging machine 1.

Please refer to Fig. 6, the ditch dredging machine 1 provided by the second preferred embodiment of the present invention is similar in structure to the first preferred embodiment.

In this embodiment, the driving member 60 is a pivot that passes through the main body 10 and the blade 18. In another embodiment, the driving member 60 can be a telescopic rod connected to the main body 10 and the blade 18, a spring or other equivalent structures that can move the blade 18. One end of the two side plates 180 is connected to the blade 18, and the other end is respectively adjacent to the left side wall 11 and the right side wall 12 of the main body 10, and is not connected to the left side wall 11 and the right side wall 12, so that it can move synchronously with the blade 18. In this way, the blade 18 can swing according to the height of the ground when encountering different heights, so that the end of the blade 18 away from the main body 10 can continue to stick to the ground. For example, when the height of the ground in front of the main body 10 is higher than the position of the main body 10, the blade 18 moves to the first position together with the movement of the main body 10, so as to scoop up higher deposits ahead; Therefore, the ditch dredging machine 1 can effectively remove deposits of different heights by changing the position of the blade 18, so as to perform cleaning operations on uneven ditch ground.

In summary, the ditch dredging machine 1 provided by the present invention controls the moving device 20, the crushing device 30 and the conveying device 40 through the processor 51, so that the ditch dredging machine 1 can automatically move in the ditch 2 and remove the silt and garbage in the ditch 2, relatively saving labor costs.

The ditch dredging machine as described in claim 1 further includes a width sensor, which is installed on the main body and electrically connected to the processor to detect the width of the ditch in front of the main body, and then generate a width signal and transmit it to the processor; if the processor judges from the width signal that the width of the ditch is not enough for the main body to pass through, the processor controls the mobile device to stop the main body from moving, and notifies a worker to go to the scene to recover the ditch dredging machine. The ditch dredging machine as described in claim 1 further includes a balance sensor, which is installed on the main body and electrically connected to the processor, to sense that the main body is in a balanced state or a tilted state, and generate A balance signal is generated and transmitted to the processor. If the processor judges that the main body is in a tilted state through the balance signal, the processor controls the mobile device to stop the main body from moving, and notifies a worker to go to the scene to recover the ditch dredging machine. The ditch dredging machine as described in claim 1 further includes a water level sensor, which is installed on the main body and electrically connected to the processor to sense the water level in the ditch, and then generate a water level signal and transmit it to the processor; if the processor judges from the water level signal that the water level at this time exceeds a water level limit value, the processor controls the mobile device to stop the main body from moving, and notifies a worker to go to the scene to recover the ditch dredging machine.
