Description

Technical Field

[0001] The utility model relates to the technical field of trenching machines, in particular to a depth limiting device for trenching machines. Background Art

[0002] The trencher is a new type of efficient and practical trenching device. After the diesel engine transmits the rotation to the clutch through the belt, it drives the travel gearbox, transmission shaft, rear axle, etc. to realize the forward or backward linear movement of the chain trencher. It is used for laying farmland pipelines, urban and rural optical cables, etc.

[0003] In the prior art, according to Chinese Patent Publication No. CN2500077, a depth limiting device for a trencher is provided, which is provided with a slide plate fixed at the lower end of a vertical shaft, and the vertical shaft is connected to a frame, and is characterized in that the position where the vertical shaft of the slide plate is connected to the frame is within the rotation radius of the cutter disc. "The rotation radius of the cutter disc" refers to the largest circle formed when the tip of the blade rotates. The optimization scheme is that the trencher frame is a short frame, and its front end is within the rotation radius of the cutter disc. This design overcomes the shortcomings of the prior art, so that the vertical shaft and the frame leave the soil throwing route of the blade, and the thrown soil blocks are no longer blocked, and can be evenly scattered on both sides, and it can be ensured that they do not fall into the already opened trench. At the same time, due to the shortening of the frame, materials are saved and costs are reduced.

[0004] The above patent has a good effect of saving materials and reducing costs, but its depth limiting device is not convenient enough for the depth adjustment operation of the cutter disc mechanism when in use, and the buffering support effect of the cutter disc support mechanism is not good, which may easily lead to safety accidents to the staff due to improper operation. Therefore, it is necessary to improve the current problems. Utility Model Content

Therefore, when it is necessary to adjust the trenching height of the cutter disc, the screw plate and the screw rod are loosened by turning the bolt. At this time, both ends of the support plate and the connecting plate can be rotated. Therefore, the trenching height of the cutter disc can be adjusted by adjusting the inclination angle of the support plate and the connecting plate as needed. After the adjustment is completed, the bolts can be tightened again to limit the trenching depth of the cutter disc. The cooperation of the two sets of rotating sleeves and the second rotating sleeve does not affect the connection strength between the cross bar and the rotating rod and the cutter disc, and the depth of the cutter disc can be easily adjusted.

[0012] The utility model is further configured as follows: a top plate is fixedly connected to the top of the upper support frame, and the number of the top plates is two.

[0013] By adopting the above technical solution, the two top plates provide a top connection mechanism for connecting and fixing the trenching machinery, which is convenient for installation and disassembly.

[0014] The utility model is further configured as follows: a collar is sleeved on the outer surface of the crossbar, a spring column is fixedly connected to the outer surface of the collar, and one end of the spring column is fixedly connected to a bottom ring.

[0015] By adopting the above technical solution, the spring column is connected between the cross bar and the rotating rod through the sleeve ring and the bottom ring, so as to provide elastic support for the rotating rod.

The different trenching depths can be adjusted. Therefore, when the trenching height of the cutter disc needs to be adjusted, the screw plate and the screw rod are loosened by turning the bolt. At this time, both ends of the support plate and the connecting plate can be rotated. Therefore, the trenching height of the cutter disc can be adjusted by adjusting the inclination angle of the support plate and the connecting plate as needed. After the adjustment is completed, the bolt can be tightened again to limit the trenching depth of the cutter disc. The cooperation of the two sets of rotating sleeves and the second rotating sleeve will not affect the connection strength between the cross bar, the rotating rod and the cutter disc, and the depth of the cutter disc can be easily adjusted.
