Sending-out mechanism of fertilizer discharger of plant protection fertilizer spraying machine

Abstract

The invention discloses a sending-out mechanism of a fertilizer discharger of a plant protection fertilizer spraying machine; the sending-out mechanism is arranged in a fertilizer discharger shell body and includes a transmission shaft, a feeding roller and a feeding amount regulating mechanism; the transmission shaft is arranged horizontally and penetrates through side plates at two sides of the fertilizer discharger shell body; the feeding roller is sleevedly arranged on the transmission shaft in the fertilizer discharger shell body; the feeding roller is a ladder-like roller body having the central axis arranged horizontally and having an inner hole increased from left to right gradually, and the left end of the roller body is provided with an end plate; a plurality of axial grooves are uniformly distributed on the roller wall of the outermost layer of the feeding roller; each axial groove is a horizontal straight groove with the left end sealed and the right end opened to split the right end of the roller wall of the outermost layer of the feeding roller; the feeding amount regulating mechanism is arranged in the fertilizer discharger shell body and at the right side of the feeding roller and includes a sliding sleeve and a regulating shaft sleeve; through regulating the regulating shaft sleeve, the left end of each axial groove of the feeding roller can be allowed to form a fertilizer accommodating groove with adjustable capacity. A fertilizer can be evenly sent out, and the quality and the effect of fertilizer spraying operations are significantly improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a sending mechanism for a fertilizer discharger of a plant protection and fertilizer spraying machine. Background technique [0002] During the growth period of crops, it is necessary to continuously replenish water and spread fertilizers in time to ensure crop yields. Now some plant protection fertilizer spraying machines replace manual fertilizer spraying operations, which are highly efficient and labor-saving. The plant protection fertilizer spraying machine discharges the fertilizer in the fertilizer storage box into the fertilizer spraying pipe through the sending mechanism in the fertilizer discharger below it, and uses the wind to send the fertilizer to the fertilizer spraying nozzle, and the fertilizer is sprinkled from the fertilizer spraying nozzle to the farmland middle. The sending mechanism of the fertilizer discharge device of the existing plant protection fe...

AI Technical Summary

Problems solved by technology

The sending mechanism of the fertilizer discharge device of the existing plant protection fertilizer spraying machine is generally a straight cylinder structure, which cannot send the fertilizer evenly, which reduces the quality and effect of the fertilizer spraying operation
