Fertilizer distributing mechanism

Abstract

The invention discloses a fertilizer distributing mechanism. The fertilizer distributing mechanism comprises a feeding device anda rotary dripping mechanism, and further comprises a base plate, the feeding device comprises a material storage box, a mixing motor, a mixingimpeller, a feed delivery pipe and a material rotating plate, a material falling hole is formed in the edge of the bottom of theinner side of the material storage box, the material falling hole is connected with the cone-shaped feed delivery pipe, a passing hole is formed in the base plate, and the feed delivery pipe penetrates through the passing hole and communicates with a counterbore formed in the upper surface of the material rotating plate; the center of the material rotating plate is a round hole, and ring-shaped grooves are formed in the inner sidethe round hole and communicates with the counterbore; and the rotary dripping mechanism comprises a fertilizer throwing barrel, a synchronous belt, a fertilizer throwing driving motor, a fixed rod and a bearing, the fixed rod is located in the center of the center round hole of the material rotating plate, the fertilizer throwing barrel is located between the fixed rod and the material rotating plate and is rotatably connected with the fixed rod through the bearing, and a material falling hole duct communicates with a discharging pipe and the ring-shaped grooves. According to the fertilizer distributing mechanism, a totally enclosed type is adopted in delivery and dripping offertilizer, and the dripping velocity is controllable.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizer spreading machinery, and in particular relates to a fertilizer spreading mechanism. Background technique [0002] At present, the spreading mechanism of the commonly used fertilizer spreader is shown in the attached manual. figure 1 As shown, it is a motor-driven disc with two vertical paddles, and the rotation of the vertical paddles generates centrifugal force to spread the fertilizer transported by the fertilizer storage hopper. This method is low in cost and stable in use. [0003] However, when this kind of fertilizer spreading mechanism encounters some fertilizers such as chemical fertilizers with lighter weight and finer particle size, due to its open structure, strong winds and bumps in the movement of the fertilizer spreader will easily cause the fertilizer to be spread in a short distance or fall off without spreading. Eventually, the fertilizer will be distributed more in the ar...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is that the existing fertilizer spreading mechanism is an open structure, and the spreading is easy to be uneven, causing phenomena such as burning seedlings and plant wilting.
