Holing device for crop fertilizers

Abstract

The invention discloses a holing device for crop fertilizers. The holing device comprises a central shaft of a first hollow structure, an electromagnet is mounted inside one end of the central shaft, the first hollow structure of the central shaft, positioned at one end of the electromagnet, sleeves an annular limit ring, a permanent magnet is disposed between the annular limit ring and the inner portion of the first hollow structure at one end of the electromagnet, a plurality of hollow columns integrally formed with a body of the central shaft are arranged on the surface thereof, and a second hollow structure is arranged in the center of every hollow column. The holing device for the crop fertilizers has the advantages that holing at intervals can be achieved; holing is quickened under the semi-automation action, so that both time and labor are saved and working efficiency can be greatly improved; the holing device as a mechanical mechanism is simple, convenient and practical without assistance of other energy sources.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a taper for crop fertilizers. Background technique [0002] At present, when crops are planted, in order to achieve the maximum effect between plants, they are often set at equal distances and at equal intervals, and heavy objects are fertilized during the growth period, and the method of fertilization is to dig holes next to the plants first, and then place them The fertilizer can be placed in the pits, but the ordinary method is more laborious when hollowing out, and tools are needed to hollow out one by one, which is time-consuming and laborious. Contents of the invention [0003] The object of the present invention is to provide a cone for fertilizers of crops to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A taper for crop chemical...
