Description

A remote control electric pit digging fertilizer applicator for orchards

technical field

The utility model belongs to the technical field of agricultural machinery, in particular to a remote-controlled electric pit-digging fertilizer applicator for orchards.

Background technique

Digging and fertilization is a commonly used method of fertilization in orchard production management. The agronomic requirement of this fertilization method is to dig 4 to 6 soil pits with an opening size of 15 to 20 cm and a depth of 30 to 60 cm on the inner side below the drip line of the crown, apply fertilizer into the pits, and then backfill with soil. Compared with fertilization methods such as radial furrow fertilization method, row furrow fertilization method and circular furrow fertilization method, this fertilization method has less damage to the root system of fruit trees and has high fertilizer utilization efficiency. At present, the digging, fertilization and soil covering operations in the orchard digging and fertilization operations are basically completed manually. The existing digging and fertilization operation machines widely used in production are mostly equipment for digging pits. These pit-digging equipment are basically divided into two categories: one is a hand-held operating machine, such as utilizing a small-sized hand-held engine power to drill a pit, after mechanically digging a pit, manually pour fertilizer into the pit and cover it with soil. In this way of operation, when the drill bit touches stones or other hard objects in the soil, it will not only affect the quality of the work, but the severe vibration of the drill bit will also increase the labor intensity of the operation and affect the safety of the operator; It is a pit digging tool matched with a tractor. Although this method of operation reduces the labor intensity of digging pits, it cannot complete fertilization and soil covering operations. After digging pits, it is still necessary to manually apply fertilizer into the pit and cover soil. Therefore, the research and development of orchard digging and fertilization operation machinery is developing towards the integrated operation of digging, fertilization, and soil covering operations. The operation sequence of digging, re-fertilizing, and finally covering soil realizes integrated operation, and the operations of digging pits and fertilizing operations are not synchronized. Moreover, various existing machines and tools with integrated functions of digging pits, fertilizing, and covering operations must stop when performing operations. Work at the work site, it cannot be carried out in the process of continuous travel, the operation efficiency is low and the cost is high The utility model provides an electric remote-controlled digging and fertilizing machine for orchards to solve the problems of high labor intensity and poor safety of manual work for digging and fertilizing, low operating efficiency and high cost of existing digging and fertilizing operation machines.
