Fertilizer application device of solid particle fertilizer

Abstract

The invention discloses a fertilizer application device of solid particle fertilizers. The fertilizer application device comprises a fertilizer applying trolley body and a charging box arranged at the top of the fertilizer applying trolley body, wherein a charging cavity is arranged in the charging box; a first rotary crushing element is arranged in the charging cavity; a crushing cavity with the top in communicated arrangement with the bottom of the charging cavity is arranged in the fertilizer applying trolley body arranged at the bottom of the charging box; second rotary crushing elements in bilateral symmetry arrangement are arranged in the crushing cavity; a sliding cavity in extending arrangement towards the left side is arranged in the fertilizer applying trolley body arranged at the bottom of the crushing cavity in a mutually communicated way; a guide groove is formed in the inner wall of the back side of the sliding cavity; a threaded rod in leftwards and rightwards extending is arranged in the guide groove; the extending tail end of the threaded rod is rotary matched connection with the inner wall of the left side of the guide groove; the extending tail end of the right side of the threaded rod is in matched connection with a first motor; the outer surface of the first motor is embedded in the inner wall of the right side of the guide groove and is fixedly connected with the inner wall of the right side of the guide groove; a sliding box is glidingly connected in the siding cavity in a matched way. The fertilizer application device has the advantages that the structure is simple; the operation is convenient; the safety is high; the crushing quality and the fertilizer application effect are improved; the workload of operators is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a fertilization device for solid granular fertilizer. Background technique [0002] At present, in the field of agriculture, after sowing, agricultural workers often need to apply fertilizers in order to promote the germination of seeds. When fertilizing, they generally put the fertilizers in the fertilizer buckets, and then manually lift the fertilizer buckets to the farmland, and then Apply fertilizer to the sowing place, but this method is time-consuming and labor-intensive, and the amount of application is not easy to control, and the fertilization efficiency is not high; in addition, during the production, processing, storage and transportation of solid granular fertilizers, caking problems often occur , which brings many difficulties to storage, transportation and use. Serious agglomeration of chemical fertilizers is difficult to break. Partial agglomeration ...

[0002] At present, in the field of agriculture, after sowing, agricultural workers often need to apply fertilizers in order to promote the germination of seeds. When fertilizing, they generally put the fertilizers in the fertilizer buckets, and then manually lift the fertilizer buckets to the farmland, and then Apply fertilizer to the sowing place, but this method is time-consuming and labor-intensive, and the amount of application is not easy to control, and the fertilization efficiency is not high; in addition, during the production, processing, storage and transportation of solid granular fertilizers, caking problems often occur , which brings many difficulties to storage, transportation and use. Serious agglomeration of chemical fertilizers is difficult to break. Partial agglomeration of chemical fertilizers is not good for mechanical fertilization, and it is easy to block the nozzle. These will bring inconvenience to fertilization, and fertilizers can be used only after crushing Plants fully absorb the fertilizer fertility, the existing fertilizer applicator has poor crushing effect, inconvenient operation, time-consuming and laborious use, and poor fertilization effect
