Nursery stock planting hole digger with tires provided with protection tracks

Abstract

The invention relates to the technical field of nursery stock planting, and discloses a nursery stock planting hole digger with tires provided with protection tracks. The nursery stock planting hole digger comprises top plates, a motor, two rotary knives, a bottom plate, the four tires and protection mechanisms; the motor is located below the top plates, the two rotary knives are located below themotor, and the bottom plate is located below the two rotary knives; the four tires are located on the left and right sides of the bottom plate, the protection mechanisms are arranged on the outer walls of the four tires, and the middles of the bottoms of the top plates are connected with the motor; a coupling is arranged at the output end of the motor, and the output end of the motor is connectedwith a rotating shaft through the coupling. According to the nursery stock planting hole digger, a rotating plate is mounted at the bottom of the rotating shaft, fixing blocks are arranged at the bottom of the rotating plate, the rotary knives are connected with the rotating plate through a fixing rod mounted at the tops of the rotary knives, after a bolt is removed manually, the rotary knives can freely move left and right so as to increase the distance between the two rotary knives, and thus the purpose of adjusting the diameter of a dug hole is achieved.

Description

technical field [0001] The invention relates to the technical field of seedling planting, in particular to a digging machine for planting seedlings with tires and protective tracks. Background technique [0002] Afforestation is a policy that our country has been vigorously promoting. With the continuous development of my country's economy and culture, garden seedling cultivation has also been greatly developed. In traditional seedling planting, in order to solve the problem of low efficiency of manual digging, people The invention of the digging machine liberates the manual hands, and the efficiency of the digging machine is largely higher than that of manual digging. However, due to the land environment problems of seedling planting, the tires of the digging machine are often worn seriously, and there will often be land The stones in the pit are stuck into the tires, and even the tires are scratched and scratched, which reduces the service life of the tires of the digging ma...

[0002] Afforestation is a policy that our country has been vigorously promoting. With the continuous development of my country's economy and culture, garden seedling cultivation has also been greatly developed. In traditional seedling planting, in order to solve the problem of low efficiency of manual digging, people The invention of the digging machine liberates the manual hands, and the efficiency of the digging machine is largely higher than that of manual digging. However, due to the land environment problems of seedling planting, the tires of the digging machine are often worn seriously, and there will often be land The stones in the pit are stuck in the tire, or even scratched and scratched the tire, which reduces the service life of the tire of the digging machine, and the existing digging machine cannot adjust the size and diameter of the pit.
