[0002] Construction work refers to the production activities during the implementation stage of project construction, which is the construction process of various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at the designated location. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc.

[0003] A trencher is one of the main types of construction machinery and is a kind of ditch-opening machine used in earthwork construction. It is widely used in farmland water conservancy construction, laying of communication cables and oil pipelines, municipal construction projects, etc.

[0004] However, in the existing trenchers for construction work, after long-term use of the trenching components at the rear of the trencher, wear, tooth loss and other phenomena will inevitably occur. At this time, it is necessary to disassemble, repair and maintain the trenching components. However, the existing trenchers for construction work cannot quickly install and disassemble the trenching components, which affects their repair and maintenance.

[0013] Optionally, a vehicle body is fixedly connected to the left side surface of the mounting bracket, and crawler wheels arranged at equal distances are fixedly installed on both the front and back surfaces of the vehicle body.

[0014] In summary, the present application includes the following beneficial technical effects:

[0015] 1. By providing components such as a connecting block, a bidirectional threaded rod, a mounting block, and a clamping block, the second connecting member is placed inside the first connecting member. At this time, by simultaneously rotating the bidirectional threaded rod, the corresponding mounting blocks are driven to move. Through the rotational connection between the connecting block and the bidirectional threaded rod, the limiting effect on the bidirectional threaded rod is achieved. At this time, the mounting blocks move relatively, and drive the corresponding clamping blocks to move, so that the clamping blocks are connected to the corresponding clamping grooves, achieving the limiting effect on the second connecting member, and further achieving the effect of installing the ditch-digging member. Conversely, rotating the bidirectional threaded rod in the reverse direction can achieve the disassembly effect, and thus the device can quickly install and disassemble the ditch-digging member, facilitating its inspection and maintenance.

[0016] 2. By providing components such as a motor, a first sprocket, a chain, and a second sprocket, the motor drives the first sprocket to rotate, and the chain is placed outside the first sprocket, and they are set to be in meshing connection. Through the first sprocket, the movement effect of the chain is achieved. The second sprocket is placed on the surface of the first connecting member and fixed thereto, and the chain is connected to the second sprocket. Through the rotation of the first sprocket, the rotation effect of the second sprocket can be achieved, thereby driving the first and second connecting members to rotate, and further driving the ditch-digging member to rotate. Through the contact between the ditch-digging member and the ground, the effect of digging a ditch is achieved. The hydraulic system is placed on the right side of the mounting bracket, and both ends of the hydraulic system are rotatable between the protective housing and the mounting bracket. Through the expansion and contraction of the hydraulic system, the protective housing rotates around the connecting rod as the center, achieving the effect of driving the ditch-digging member to lift, and thus being able to adjust the depth of the ditch-digging.
