Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer processing technology, specifically an organic fertilizer raw material crushing device. Background Technology

[0002] Organic fertilizer, also known as "farmyard manure," refers to any fertilizer made from organic matter (compounds containing carbon). This includes human excrement, manure, compost, green manure, oilseed cake, and biogas slurry. It is characterized by its variety, wide availability, and long-lasting effects. The nutrients in organic fertilizers are mostly in an organic state, which crops cannot directly utilize. Through the action of microorganisms, various nutrients are slowly released, continuously supplying nutrients to crops. Applying organic fertilizer improves soil structure, balances water, fertilizer, air, and heat in the soil, and enhances soil fertility and land productivity. During the processing of organic fertilizer, these waste materials need to be crushed using a crusher. However, existing crushers only use a single crushing roller, resulting in ineffective crushing. Manual feeding and repeated crushing are required, reducing production efficiency and wasting time. Therefore, there is a need to develop an organic fertilizer raw material crushing device that can enhance the crushing effect and improve production efficiency. Utility Model Content

[0003] To address the above technical problems, this utility model provides an organic fertilizer raw material crushing device that can enhance the crushing effect of organic fertilizer and improve production efficiency. This solves the problems of the existing single crushing roller having an insignificant crushing effect, requiring manual feeding for secondary or multiple repeated crushing, reducing production efficiency and wasting production time.

[0004] To solve the above-mentioned technical problems, the present invention provides an organic fertilizer raw material crushing device, comprising a shell, a box body fixedly connected to one side of the upper end of the shell, a crushing roller assembly rotatably connected inside the box body, a feed inlet at the upper end of the box body, a crushing chamber connected to the lower end of the box body, a pair of crushing rollers rotatably connected inside the crushing chamber, the crushing rollers being controlled by a crushing motor fixedly connected to the bottom end of the crushing chamber, a sieve plate fixedly connected to the bottom of the shell, a collection hopper fixedly connected to the bottom of the sieve plate, a motor fixedly connected to the upper end of the shell, a connecting rod fixedly connected to the output end of the motor penetrating the top of the shell, and a scraper fixedly connected to the bottom end of the connecting rod.

[0005] Furthermore, the crushing roller assembly includes several crushing rollers, one end of each crushing roller is fitted with a crushing roller gear, the crushing roller gears are meshed with each other, and one end of each crushing roller is fixedly connected to the output end of a crushing roller motor.

[0006] Furthermore, the upper ends of the shafts of the two crushing rollers are rotatably connected to the housing, and the lower ends penetrate the bottom of the crushing chamber and are rotatably connected to the crushing chamber. The lower end of the shaft of one crushing roller is fixedly connected to the drive gear and the output end of the crushing motor, and the lower end of the shaft of the other crushing roller is fixedly connected to a driven gear. The drive gear and the driven gear are meshed together.

[0007] Furthermore, a support leg is fixedly connected to the bottom of the hopper.

[0008] Furthermore, the bottom plate of the box is an inclined plate that tilts towards the crushing roller.

[0009] Furthermore, a collection trough is provided below the collection hopper.

[0010] This utility model has the following advantages compared with the prior art:

[0011] This invention uses a rotating crushing roller assembly inside the housing to perform a first treatment on large pieces of organic fertilizer. A second treatment is performed on the broken organic fertilizer using a rotating crushing roller assembly inside the crushing chamber. A third treatment is performed on the organic fertilizer using a scraper and a screen plate fixedly connected to the bottom of the connecting rod. The scraper crushes the organic fertilizer, and organic fertilizer that meets the particle size standard falls along the aperture of the screen plate and enters the collection trough along the side wall of the collection hopper, thus completing the crushing process of the organic fertilizer.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 , 2An organic fertilizer raw material crushing device shown in Figure 3 includes a shell 1. A box 2 is fixedly connected to one side of the upper end of the shell 1. In order to crush large pieces of organic fertilizer, a crushing roller group 3 is rotatably connected inside the box 2. A feed inlet 4 is opened at the upper end of the box 2. In order to further crush the crushed organic fertilizer, a crushing chamber 5 is connected to the lower end of the box 2. A pair of crushing rollers 6 are rotatably connected inside the crushing chamber 5. The crushing rollers 6 are controlled by a crushing motor 7 fixedly connected to the bottom end of the crushing chamber 5. In order to control the size of the organic fertilizer within the required particle size range, a screen plate 10 is fixedly connected to the bottom of the shell 1. A collection hopper 11 is fixedly connected to the bottom of the screen plate 10. A motor 12 is fixedly connected to the upper end of the shell 1. A connecting rod 13 penetrating the top of the shell 1 is fixedly connected to the output end of the motor 12. A scraper 14 is fixedly connected to the bottom end of the connecting rod 13.

[0018] To facilitate the crushing of large pieces of organic fertilizer, the crushing roller assembly 3 includes several crushing rollers. A crushing roller gear 17 is fitted onto one end of each crushing roller, and the crushing roller gears 17 are meshed together. One end of each crushing roller is fixedly connected to the output end of the crushing roller motor 18.

[0019] To facilitate further crushing of organic fertilizer, the upper ends of the shafts of the two crushing rollers 6 are rotatably connected to the housing 1, and the lower ends pass through the bottom of the crushing chamber 5 and are rotatably connected to the crushing chamber 5. The lower end of the shaft of one crushing roller 6 is fixedly connected to the drive gear 8 and the output end of the crushing motor 7, and the lower end of the shaft of the other crushing roller 6 is fixedly connected to the driven gear 9.
