Description

Technical Field

[0001] The present invention relates to the technical field of fertilizer production from bamboo shoot residues, and specifically to a fertilizer production device for bamboo shoot processing residues. Background Art

[0002] During bamboo shoot processing, the aged shoot tips at the lower end of the bamboo shoots (the shoot tips refer to the old parts at the root of the bamboo shoots) need to be cut off, and the outer bamboo shoot sheaths (the bamboo shoot sheaths are also called bamboo shoot skins) need to be removed. The shoot tips and bamboo shoot sheaths can be collectively called: bamboo shoot processing residues. In order not to waste the resources of bamboo shoot sheaths and shoot tips, a recycling crusher is usually used to crush the bamboo shoot sheaths, and then the crushed materials are fermented into fertilizer to realize the rational utilization of bamboo shoot sheath resources.

The balls 14 are used to reduce the friction between the fermentation frame 8 and the bottom plate 2. The balls 14 reduce the friction between the fermentation frame 8 and the bottom plate 2, which is convenient for pushing the fermentation frame 8 to reciprocate under the action of the push-pull component.

[0049] The push-pull component includes a fixed plate 15 fixedly connected to the bottom plate 2. A spring 16 is fixedly connected to the fixed plate 15. A push plate 17 is fixedly connected to the end of the spring 16. An inverted U-shaped plate 18 is clamped between the push plate 17 and the fermentation frame 8.

[0051] While the screw rod 6 rotates forward to drive the screening frame 3 to move downward, the rope winding wheel 19 releases the pulling rope 20. Under the action of the elastic force of the spring 16, the fermentation frame 8 is pushed to move to one side away from the fixed plate 15, so that the bamboo shoot husks discharged from the discharge pipe 7 can be evenly distributed in layers in the fermentation frame 8; when the screw rod 6 rotates reversely to drive the screening frame 3 to move upward to the initial position, the rope winding wheel 19 winds up the pulling rope 20 against the elastic force of the spring 16, pulling the fermentation frame 8 to move to the initial position, so that the crushed bamboo shoot husks can be evenly distributed in the fermentation frame 8.

[0052] Support plates 34 are fixedly connected to both the fixed plate 15 and the box body 1. A guide rope wheel 35 for changing the pulling rope 20 is rotatably connected to the support plate 34. The guide rope wheel 35 is rotatably connected to the support plate 34 through a rotating rod and a bearing, and the guide rope wheel 35 is used to change the direction of the pulling rope 20.

[0053] The decomposer spraying assembly includes a liquid storage frame 21 and a liquid storage tank 22. The liquid storage frame 21 and the liquid storage tank 22 are both fixedly connected to the bottom plate 2. The decomposer can promote the decomposition and fermentation of bamboo shoot husks. A connecting pipe 23 is provided between the liquid storage frame 21 and the liquid storage tank 22, and an inlet check valve 24 is provided on the connecting pipe 23. A spraying pipe 25 is fixedly connected to the discharge pipe 7, and a number of spray holes are opened on the spraying pipe 25.

A pressing assembly is provided between the fermentation frame 8 and the liquid storage frame 21 for pushing the decomposer in the liquid storage frame 21 to flow into the delivery pipe 26.

[0054] When the fermentation frame 8 moves to one side away from the fixed plate 15, it will push the moving plate 28 closer to the liquid storage frame 21. Under the action of the connecting rod 29, the swing rod 30 and the transmission rod 32, the piston plate 31 will be pushed downward to compress the decomposer in the liquid storage frame 21. The decomposer can be transported to the spraying pipe 25 through the delivery pipe 26, and can spray the decomposer on each layer of bamboo shoot husks distributed in the fermentation frame 8, which is convenient for accelerating the fermentation of bamboo shoot husks and improving the efficiency of making fertilizer from bamboo shoot husks. When the fermentation frame 8 is filled with bamboo shoot husks, the fermentation frame 8 can be quickly removed for sealing treatment, which is convenient for fermenting and making fertilizer from the crushed bamboo shoot husks.

The transmission rod 32 is hinged to the bottom of the swing rod 30.

[0056] When the moving plate 28 moves towards the side close to the liquid storage frame 21, under the driving action of the connecting rod 29, it will push the swing rod 30 to swing around the hinge point with the liquid storage frame 21. The bottom end of the swing rod 30 swings downward, and under the action of the transmission rod 32, it will push the piston plate 31 to move downward. With the cooperation of the liquid outlet check valve 27, the downward movement of the piston plate 31 will thus push the decomposed agent in the liquid storage frame 21 to enter the spraying pipe 25 through the conveying pipe 26. When the fermentation frame 8 drives the moving plate 28 to move towards the side away from the liquid storage frame 21, the bottom end of the swing rod 30 will swing upward. Under the action of the transmission rod 32, it will pull the piston plate 31 to move upward. Under the action of the liquid inlet check valve 27, the decomposed agent in the liquid storage tank 22 can be extracted into the liquid storage frame 21.

[0057] A slider is fixedly connected to the bottom of the moving plate 28. A sliding groove 33 for the slider to slide is formed on the bottom plate 2.
