Pit digging machine for fruit tree planting

Abstract

The invention belongs to the technical field of digging machinery for sowing or planting and particularly discloses a pit digging machine for fruit tree planting. The pit digging machine comprises a digging unit, a mixing unit and a mobile trolley, wherein the digging unit comprises a motor, a cylinder and a screw-in rod, a concave cavity is formed in the upper part of the screw-in rod, a screw blade is arranged on the screw-in rod, an output shaft of the motor is connected with a rotating shaft, a push column is in threaded connection onto the rotating shaft, and a tension spring is connectedbetween the cylinder and the upper part of the screw-in rod; the mixing unit comprises a hopper, a piston barrel, a rotating column and a mixing barrel, the lower part of the piston barrel extends into a cavity of the rotating column, a drive mechanism is connected between the output shaft of the motor and the rotating column, a curved groove is formed in the inner wall of the rotating column, aplunger is glidingly connected in the piston barrel, a bulging strip is connected onto the plunger, a sieve plate is glidingly connected in the mixing barrel, a spring is connected between the sieve plate and the mixing barrel, and a stirring shaft located in the mixing barrel is arranged on the rotating column. By means of the pit digging machine, the following fertilization uniformity can be guaranteed while the pit digging efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of excavating machinery for sowing or planting, and in particular relates to a digging machine for planting fruit trees. Background technique [0002] When planting fruit trees, in order to improve the survival rate, fruit tree saplings are generally planted. The roots of the fruit tree saplings need to be planted underground and buried in the soil. The saplings are buried in the pit to complete the planting of the fruit tree saplings. [0003] When planting fruit tree saplings and digging holes, the staff usually use shovels to excavate the land. After digging the hole, place the fruit tree saplings vertically in the hole, then fill the soil around the hole into the hole, and finally apply fertilizer In the soil, the fruit tree planting is completed. There are following defects in adopting the above-mentioned method to plant saplings: 1, manual excavation wastes a lot of manpower and material resources, a...

AI Technical Summary

Problems solved by technology

There are following defects in adopting the above-mentioned method to plant saplings: 1, manual excavation wastes a lot of manpower and material resources, and the work efficiency is low, and the labor burden of the staff is large

2. After digging the pit, use the soil around the pit to fill the pit, which will cause the ground around the pit to be uneven. When irrigating the planted fruit trees, it is easy to make the fruit tree saplings be washed away by the water.

3. Fertilize after planting, the fertilizer distribution is uneven, and the fruit trees cannot absorb fertilizer well
