Breaking anti-blockage uniform application fertilizer apparatus with multi-stage breaking function

Abstract

The invention discloses a breaking anti-blockage uniform application fertilizer apparatus with a multi-stage breaking function, and belongs to the agricultural machines. A left driving gear shaft anda right driving gear shaft which are engaged are rotatably assembled on the lower portion of a shell and transfer motion to a left driven gear shaft and a right driven gear shaft through a left transition gear shaft and a right transition gear shaft, a left rotation involute fertilizer discharging gear and a right rotation involute fertilizer discharging gear are fixedly arranged in the middles ofthe left and right driving gear shafts, right rotation cone ridge breaking rollers with spiral anti-sticking breaking cone ridges evenly distributed in the circumferential direction are fixedly arranged in the middles of the left and right driven gear shafts, the spiral anti-sticking breaking cone ridges which are in right rotation spiral line shapes are composed of cone faces and saddle faces which are alternatively arranged, and the centering gap of the right rotation cone ridge breaking roller is larger than the side wall gap. Through impact circular rotation roll extruding breaking effectof the breaking roller, large block fertilizer is broken into small fertilizer and bulk fertilizer, inner circular flow is used for further breaking, an inclined tooth involute fertilizer discharginggear is used for carrying out fertilizer secondary breaking, and then discharging is achieved in a uniform and constant manner. Meanwhile, the fertilizer apparatus is novel in structure, high in reliability and high in adaptation.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a crushing, anti-blocking and uniform fertilizer discharger with multi-stage crushing function. Background technique [0002] Granular fertilizers are often agglomerated during storage and transportation due to the formation of crystal connections between particles (that is, "crystal bridges"), which has caused headaches for many farmers and dealers, especially when fertilizers are stacked in warehouses for a period time, it is most likely to cause agglomeration of granular fertilizers, and the longer the time, the more serious the agglomeration problem. Therefore, before fertilization, it is necessary to manually or mechanically crush and pretreat the agglomerated fertilizer, which has high production costs and high labor intensity, and the agglomerated fertilizer still remains after the crushed fertilizer. Fertilizers, horizontal screw conveying fertilizer devices, and no-tillage...

Problems solved by technology

[0002] Granular fertilizers are often agglomerated during storage and transportation due to the formation of crystal connections between particles (that is, "crystal bridges"), which has caused headaches for many farmers and dealers, especially when fertilizers are stacked in warehouses for a period Time, the most likely to cause agglomeration of granular fertilizers, and the longer the time, the more serious the agglomeration problem

Therefore, before fertilization, it is necessary to manually or mechanically crush and pretreat the agglomerated fertilizer, which has high production costs and high labor intensity, and the agglomerated fertilizer still remains after the crushed fertilizer. Fertilizers, horizontal screw conveying fertilizer devices, and no-tillage spiral groove wheel fertilizer devices do not have the design function of crushing and discharging fertilizers. Therefore, the applicant (Northeast Forestry University) invented a gap meshing involute helical gear to solve this problem. The anti-blocking fertilizer discharge device (patent number: CN201820823354.X), which uses a pair of involute helical fertilizer discharge wheels to reverse the center and reverse the way to crush and discharge fertilizers, has better operation quality and good fertilizer discharge flow uniformity, but During its practical application, it was found that due to its special involute helical tooth fertilizer wheel structure, it has a certain limit on the crushing size of the agglomerated fertilizer. When the size of the agglomerated fertilizer is too large, the crushing effect is poor and the time long, which affects the normal operation of the fertilizer discharger, and sometimes there is a problem that the agglomerated fertilizer stays on the upper part of the two rows of fertilizer wheels and blocks the fertilizer discharger. Technology, research and development of a new type of anti-clogging fertilizer discharger with multi-stage crushing of large agglomerated fertilizers, good crushing effect, and good uniformity of fertilizer discharge flow, has important practical significance and certain market application prospects
