Description

Technical Field

[0001] The utility model relates to the technical field of agricultural fertilization, and particularly relates to an anti-jamming type solid organic fertilizer spreader. Background Technique

[0002] With the development of the economy, more and more agricultural machinery is used in agricultural production, such as seeders, harvesters, and fertilizer spreaders, etc. While greatly reducing the labor intensity of farmers, it also greatly improves labor efficiency. However, when a large amount of fertilizer is put into the existing fertilizer spreader, there is a risk of blocking the feeding port, resulting in the interruption of fertilizer spreading and affecting work efficiency.

[0003] In the prior art, for example, in a Chinese patent with the publication number CN217011777U and the name of a fertilizer sprinkling device for agricultural mechanized production, the disclosed technical solution records that it includes a fertilization cart body. A fertilization port is fixedly installed in the middle of the upper end of the fertilization cart body. A fertilizer storage barrel is fixedly installed at the upper end of the fertilization port. A partition board is fixedly installed below the inner wall of the fertilizer storage barrel. Drop holes are symmetrically opened at the upper end of the partition board. A screen is fixedly connected to the inner wall of the drop hole. A sealing box is fixedly installed at the lower end of the partition board. A stirring motor is fixedly installed on the lower inner wall of the sealing box. By using the stirring motor and the driving rod in the fertilizer storage barrel in cooperation, the blocked fertilizer on the surface of the screen is dredged. Also, by using the cooperation of the grinding block and the side dredging column, the caked fertilizer is broken up, thereby effectively improving the fertilizer sprinkling efficiency. By comparing with related technical fields and similar technical solutions, although the fertilizer is broken up in the fertilizer storage barrel, the fertilizer in the feeding port still has the possibility of being blocked. Content of the Utility Model

[0004] The utility model provides an anti-jamming type solid organic fertilizer spreader to solve the above problems.

[0005] The utility model adopts the following technical scheme: an anti-jamming type solid organic fertilizer spreader, which includes a fertilizer hopper, a frame, a spreading mechanism and an anti-blocking mechanism; an inlet is provided at the top end of the fertilizer hopper, and a discharge port is provided at the bottom end of the fertilizer hopper; the frame is used to fix the fertilizer hopper, the spreading mechanism and the anti-blocking mechanism; the spreading mechanism is arranged below the fertilizer hopper and is used to evenly sprinkle the fertilizer falling from the fertilizer hopper on the field; the anti-blocking mechanism includes an anti-blocking rod, anti-blocking claws, a connecting rod, a sliding ring and a limiting block. The anti-blocking rod is arranged in the discharge port. The anti-blocking claws are hinged to the top of the anti-blocking rod. The connecting rod is hinged to the lower end of the anti-blocking claws. The lower end of the connecting rod is hinged to the sliding ring. The sliding ring is slidably installed on the anti-blocking rod. The limiting block is fixedly installed on the anti-blocking rod; the anti-blocking rod moves vertically up and down in the discharge port. When the anti-blocking rod moves upward, the anti-blocking claws close under the action of the fertilizer in the fertilizer hopper and stick to the anti-blocking rod; when the anti-blocking rod moves downward, the anti-blocking claws open under the action of the fertilizer in the fertilizer hopper. When the anti-blocking claws open, the sliding ring is driven by the connecting rod to move axially upward on the anti-blocking rod. When the sliding ring touches the limiting block, it stops sliding, so that the anti-blocking claws maintain a certain opening angle when the anti-blocking rod moves downward; the fertilizer in the discharge port is disturbed by the up and down movement of the anti-blocking rod to prevent the fertilizer in the discharge port from being blocked. At the same time, when the anti-blocking claws move downward with the anti-blocking rod, they open at a certain angle to take out the fertilizer in the discharge port, further solving the problem of fertilizer blockage in the discharge port.

[0006] Further, the frame includes a connecting frame, a fixing frame and an installation cylinder. The fixing frame is fixedly installed at the top end of the connecting frame. The installation cylinder is fixedly installed at the bottom end of the connecting frame. A linkage shaft is arranged in the installation cylinder. The linkage shaft is rotationally connected to the installation cylinder; one end of the linkage shaft extending out of the installation cylinder is rotationally connected to a motor, and the motor is fixedly installed on the connecting frame.

[0007] Further, the spreading mechanism includes a spreading disk, a material guiding plate, a first bevel gear and a second bevel gear; the spreading disk is arranged below the discharge port. The spreading disk is rotatably installed on the upper end surface of the installation cylinder. A plurality of material guiding plates are provided. The material guiding plates are fixedly installed on the upper end surface of the spreading disk. The first bevel gear is fixedly installed on the lower end surface of the spreading disk. The second bevel gear is fixedly installed on the linkage shaft. The first bevel gear and the second bevel gear are meshed. An arc-shaped baffle is arranged on one side of the spreading disk close to the connecting frame. The baffle is fixedly installed on the connecting frame; the linkage shaft drives the spreading disk to rotate through the meshing of the first bevel gear and the second bevel gear. The fertilizer falls from the discharge port into the spreading disk. The spreading disk rotates and evenly sprinkles the fertilizer on the field through the material guiding plates; the baffle blocks the fertilizer sprinkled towards the motor direction to protect the motor.

[0008] A connecting rod mechanism is rotatably installed at the bottom end of the anti-blocking rod. The other end of the connecting rod mechanism is rotationally connected to the linkage shaft; the bottom end of the anti-blocking rod penetrates through the spreading disk, and the anti-blocking rod is slidably connected to the spreading disk; the top end of the anti-blocking rod is conical; the linkage shaft converts its rotational motion into the up and down movement of the anti-blocking rod through the connecting rod mechanism; the top end of the anti-blocking rod being conical is beneficial for the anti-blocking rod to move upward in the fertilizer.

[0009] The beneficial effects are as follows: The linkage shaft drives the anti-blocking rod to move up and down in the feeding port through a linkage mechanism. When the anti-blocking rod moves upward, the anti-blocking claws close under the action of the fertilizer in the fertilizer hopper and stick to the anti-blocking rod. When the anti-blocking rod moves downward, the anti-blocking claws open under the action of the fertilizer in the fertilizer hopper. When the anti-blocking claws open, the sliding ring is driven by the connecting rod to move upward along the axis on the anti-blocking rod and stops sliding when it touches the limit block, so that the anti-blocking claws maintain a certain opening angle when the anti-blocking rod moves downward. The fertilizer in the feeding port is disturbed by the up and down movement of the anti-blocking rod to prevent the fertilizer in the feeding port from being blocked. At the same time, the anti-blocking claws open at a certain angle when moving downward with the anti-blocking rod, and the fertilizer in the feeding port is taken out, further solving the problem of fertilizer blockage in the feeding port.
