Reverse meshing gear type fertilizer applying device

Abstract

Reverse meshing gear type fertilizer applying device belongs to the agricultural machinery. A fertilizer inlet and a fertilizer outlet are respectively arranged at the upper end and the lower end of a fertilizer applying box of the fertilizer applying device; a driven gear for fertilizer applying is rotatably assembled to the right inside of the fertilizer applying box through a pin shaft, the driven gear for fertilizer applying is meshed with a driving gear for fertilizer applying; an inner hexagon sleeve is fixedly installed inside of the driving gear for fertilizer applying through a set screw, and the inner hexagon sleeve is rotatably assembled in the left inside of the fertilizer applying box. The fertilizer at the fertilizer inlet of the fertilizer applying box is transferred to the fertilizer outlet continuously and alternately along with the movement of alveolus on both sides of the fertilizer applying box through the rotation of the driving gear for fertilizer applying and the driven gear for fertilizer applying which are external meshed mutually. The uniformity of the fertilizer applying flow is increased by the continuous and alternating impact and mixing of the fertilizer. Meanwhile, the fertilizer applying device has the characteristics of novel, simple and reasonable structure, reliable quality and wide applicability.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a reverse meshing gear type fertilizer discharger. Background technique [0002] At present, the outer grooved wheel fertilizer is widely used because of its simple structure, strong adaptability, stable fertilizer output, convenient adjustment and reliable operation. Fertilizer, when the groove of the sheave passes through the end of the fertilizer discharge tongue, the displacement increases, and when the tooth ridge passes through the end of the fertilizer discharge tongue, the displacement decreases, the fertilizer discharge flow is in a pulsating state, and the fertilizer discharge uniformity is poor. It will lead to uneven distribution of fertilizer in the field, so that one crop is over-fertilized, while another crop is under-fertilized, which not only causes waste of fertilizer, but also reduces the utilization rate of fertilizer. Therefore, it is necessary to design a ferti...

[0002] At present, the outer grooved wheel fertilizer is widely used because of its simple structure, strong adaptability, stable fertilizer output, convenient adjustment and reliable operation. Fertilizer, when the groove of the sheave passes through the end of the fertilizer discharge tongue, the displacement increases, and when the tooth ridge passes through the end of the fertilizer discharge tongue, the displacement decreases, the fertilizer discharge flow is in a pulsating state, and the fertilizer discharge uniformity is poor. It will lead to uneven distribution of fertilizer in the field, so that one crop is over-fertilized, while another crop is under-fertilized, which not only causes waste of fertilizer, but also reduces the utilization rate of fertilizer. Therefore, it is necessary to design a fertilizer discharger with uniform fertilizer flow rate. , has important theoretical and practical significance
