Hole-fertilization operating device for orchards

Abstract

The invention provides a hole-fertilization operating device for orchards. The hole-fertilization operating device comprises a stander, a hole digging mechanism, a fertilizer ejecting mechanism, a linkage mechanism and an elastic soil returning plate, wherein the hole digging mechanism is hinged with the left lower part of the stander through a hinge, the fertilizer ejecting mechanism is fixedly mounted at the right upper part of the stander, the linkage mechanism is fixedly mounted in the middle of the stander, and the elastic soil returning plate is fixedly mounted below the left side of the stander; two ends of a soft shaft pull wire are hinged to the small end of a connecting bar of the hole digging mechanism and the left end of a fertilizer ejecting baffle of the fertilizer ejecting mechanism. The hole digging operation performed by the hole digging mechanism and the fertilizer ejecting operation performed by the fertilizer ejecting mechanism are synchronously carried out, and the soil covering operation is automatically finished by virtue of the elastic soil returning plate after the hole digging operation and the fertilizer ejecting operation, so that the integration of the hole digging operation, the fertilizer ejecting operation and the soil covering operation is realized, the fertilizer ejecting operation and the hole digging operation are synchronously realized, the efficiency is high, and the practicability is strong; the hole-fertilization operating device has relatively high popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an orchard fertilizer hole application device. Background technique [0002] Point application is a commonly used fertilization method for orchard or densely planted orchard management in arid areas. 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 of the tree crown (below the drip line of the tree crown), apply the prepared fertilizer into the pit, and then backfill the soil. . Compared with fertilization methods such as radial furrow fertilization method, row furrow fertilization method and circular furrow fertilization method, this fertilization method not only has less damage to the root system of fruit trees, but also has high fertilizer utilization efficiency. [0003] At present, the pit digging, fertilizer discharge and soil coveri...

AI Technical Summary

Problems solved by technology

[0003] At present, the pit digging, fertilizer discharge and soil covering operations in the point fertilization method are basically done manually. The mechanized operation of point fertilization has not been widely used in the production management of orchards. One important reason is that the existing The hole-like point construction operation machinery has the problems of low operation efficiency and single operation function

Most of the mechanized operations of pit-like point fertilization use digging machines to dig holes and open holes first, and then manually discharge fertilizer and cover soil. , re-fertilization and final soil covering to complete the fertilization operation, and the synchronous operation of digging pits, fertilizer discharge and soil covering has not yet been realized
