Backpack electric fertilizer applicator capable of crushing caking fertilizers

Abstract

The invention discloses a backpack electric fertilizer applicator capable of crushing caking fertilizers. The backpack electric fertilizer applicator comprises a barrel, and first, second and third partition plates are arranged in the barrel sequentially from bottom to top. An impeller is rotatably connected, at the geometric center of a bottom plate of the barrel, between the first partition plate and the bottom plate of the barrel. A motor and a screw are arranged on two sides of the impeller respectively. The upper end of the screw penetrates the first, second and third partition plates sequentially and rotatably connected with the barrel, and the lower end of the screw is rotatably connected with the bottom plate of the barrel. The second and third partition plates are both in funnel shapes, and a sharp end of the second partition plate is provided with a second leak hole corresponding to a first leak hole in the first partition plate. A collection plate extending downwards is arranged at a sharp end of the third partition plate and provided with a through hole allowing penetration of the screw, and a crushing plate is arranged at a position, below the collection plate, of the screw. The collection plate and the crushing plate are provided with third leak holes respectively. In application of the fertilizer applicator, the caking fertilizers can be crushed to avoid blockage.

Description

technical field [0001] The invention relates to the field of a backpack type fertilizer applicator, in particular to a backpack type electric fertilizer applicator capable of breaking agglomerates. Background technique [0002] For rice, due to the soft soil in the paddy field, traditional agricultural machinery cannot enter, so it can only be fertilized manually. However, artificial fertilization is not only inefficient and uneven, but also direct contact with fertilizer for a long time will burn the skin of workers' hands, which is harmful to health. [0003] Aiming at this problem, the patent No. 201220609865.4 discloses a knapsack electric fertilizer spreader. However, due to the influence of the humid environment, agglomeration often occurs in the chemical fertilizer. When the agglomerated fertilizer is directly introduced into the fertilizer box, the agglomerated fertilizer is easy to block the fertilizer outlet. When this happens, the fertilizer can only be poured ou...

Problems solved by technology

However, due to the influence of the humid environment, agglomeration often occurs in the chemical fertilizer. When the agglomerated fertilizer is directly introduced into the fertilizer box, the agglomerated fertilizer is easy to block the fertilizer outlet. When this happens, the fertilizer can only be poured out. out, and then take out the agglomerated fertilizer, which greatly reduces the work efficiency
