Description

Ditch dredging machine

This creation is related to the dredging project, especially a ditch dredger that can automatically move in the ditch to remove accumulations 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 on-the-spot investigation, 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.

The ditch dredging machine as described in claim 1, further comprising a storage capacity sensor installed in the storage area of the main body and electrically connected to the processor to detect the amount of accumulation in the storage area storage capacity, according to which a storage capacity signal is generated and transmitted to the processor; if the processor judges that the storage capacity of the storage area exceeds a storage capacity limit value through the storage capacity signal, the processor controls the mobile device to make the The subject stops moving, and a worker is called to the scene to remove the accumulation in the storage area. The ditch dredging machine as described in claim 1, further comprising 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, according to to 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 body to pass through, the processor controls the mobile device to stop the body from moving, and notifies A staff went to the scene to recover the ditch dredger. 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 transmitted to the processor, and 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 staff member 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 generate a The water level signal is transmitted 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 staff member Go to the site to recover the ditch dredging machine.
