Description

Technical Field

[0001] The utility model relates to the technical field of seedling root cutting machines, in particular to a seedling root cutting machine. Background Art

[0002] A seedling root cutting machine can greatly improve the efficiency of manual seedling digging and increase the survival rate of seedlings. The seedling root cutting machine can easily cut into the soil and saw off the tree roots in the soil. It is mainly used for digging root balls with soil during tree transplanting, barreling or felling and renewal of eliminated trees.

[0003] According to the description of a seedling root cutter disclosed in the patent website (authorization announcement number: CN 213991925 U), "the utility model discloses a seedling root cutter, whose structure includes a handle, a diesel engine, a fuel tank, a starter box, a connecting rod, a shock absorbing device, and a shovel plate. The handle is fixedly connected to the left and right ends of the rear of the diesel engine, the fuel tank is fixedly connected to the bottom of the diesel engine, the starter box is bolted to the rear of the fuel tank, the shock absorbing device is connected to the bottom of the starter box through a connecting rod, and the shovel plate is connected to the bottom of the shock absorbing device. The shock absorbing device is mainly composed of a bottom plate, a compression pad, a spring base, a first spring, a second spring, a support shell, an outer shell, and a compression column. The second spring is welded to the left end of the bottom plate. The utility model adds a shock absorbing device, so that when the machine is working, the vibration will be buffered by the shock absorbing device before reaching the machine, making the machine more stable and not easily controlled by vibration shaking. It can better help the staff to use the machine without being disturbed by other factors, thereby increasing work efficiency."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model starts working by inserting the shovel plate into the soil and onto the tree roots. When the vibration is fed back to the machine, the first spring and the second spring in the shock absorbing device buffer the force. When the outer shell and the bottom plate are compressed, the compression column in the support shell presses the compression pad. In actual use, since the shovel plate of the device is fixedly installed, the device cannot replace the shovel plate according to the soil environment of different use occasions. At the same time, the device is manually held by the staff, and the staff's grip strength is different. When encountering a harder soil environment, it is easy to slip out of the hand and other unexpected situations. At the same time, the cutting process of the device requires the staff to manually press down to cut, which increases the workload of the staff and reduces the work efficiency. Therefore, it is necessary to improve a seedling root cutting machine to solve the above problems. Utility Model Content
