However, these raw materials need to be crushed during pretreatment. It is not convenient to crush such high-moisture materials, resulting in low crushing efficiency and thus reducing production efficiency. Utility Model Content
[0004] This utility model provides a pre-processing machine for biological organic fertilizer raw materials, which aims to solve the problem that the raw materials are relatively soft and viscous due to their high humidity, but need to be crushed during pre-processing, which is inconvenient when processing such high humidity materials.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0019] Please see Figure 1-3 This utility model provides a technical solution: a pretreatment machine for biological organic fertilizer raw materials, including a dehydration chamber 1 and a crushing chamber 2. The dehydration chamber 1 is obliquely arranged on one side of the crushing chamber 2. A filter screen is provided at the bottom of the dehydration chamber 1. A feed hopper 13 is provided at the top of the bottom of the dehydration chamber 1. A discharge port is provided at the bottom of the dehydration chamber 1 and below the discharge port. A feed pipe 5 extending into the crushing chamber 2 is provided at the bottom of the dehydration chamber 1 and below the discharge port. Several spiral blades 3 are rotatably arranged along the length of the inner cavity of the dehydration chamber 1 and in front of the discharge port. A movable plate 4 is movably arranged at the top of the inner cavity of the dehydration chamber 1 to prevent materials from entering the discharge port.
[0020] The filter screen is used to remove moisture or liquid from the material, ensuring that the material entering the crushing chamber 2 is dry.
[0021] The feces are poured into the dehydration chamber 1 through the feed hopper 13 for dehydration treatment.
[0022] After the fecal material is poured into the dewatering chamber 1, the movable plate 4 is driven to move to the front of the discharge port. The rotating spiral blade 3 drives the material forward, thereby squeezing the material with the movable plate 4 to achieve solid-liquid separation. The water flows down through the filter screen.
[0023] After extrusion, the material flows out from the feed pipe 5 by driving the movable plate 4 to move backward.
[0024] Two arc-shaped guide plates 7 are provided above the inner cavity of the crushing chamber 2. Scrapers 8 for wiping the surface of the arc-shaped guide plates 7 are slidably provided in the inner cavities at both ends of the crushing chamber 2 along the length direction of the arc-shaped guide plates 7. Two relatively rotating crushing rollers 6 are provided in the inner cavity of the crushing chamber 2 and below the two arc-shaped guide plates 7. A discharge pipe 16 is provided at the bottom of the crushing chamber 2.
[0025] The scraper 8 can wipe the material on the arc-shaped guide plate 7 to prevent material accumulation or blockage.
[0026] After the material enters the crushing chamber 2, it flows through the arc-shaped guide plate 7 to the space between the two crushing rollers 6. Then, the two crushing rollers 6 are activated to crush the material. During the crushing process, the scraper 8 slides along the length of the arc-shaped guide plate 7, constantly wiping the surface of the guide plate. Finally, the material is discharged outward through the discharge pipe 16.
[0027] Furthermore, a receiving box 11 is obliquely arranged at the bottom center of the dehydration chamber 1. A first motor 12 is arranged inside the receiving box 11. The output shaft of the first motor 12 is fixedly connected to a first rotating shaft 14. Several spiral blades 3 are fixedly connected to the surface of the first rotating shaft 14.
[0028] When dehydration is required, the first motor 12 is started to drive the first rotating shaft 14 to rotate, which in turn drives the spiral blades 3 to rotate, thereby transporting the material upward until the material is in contact with the movable plate 4, so that the moisture in the material is removed and solid-liquid separation is achieved.
[0029] Furthermore, a water receiving trough 9 is provided at the bottom of the dehydration chamber 1, and a baffle 10 is provided on the rear side of the water receiving trough 9.
[0030] When the wet material enters the dewatering chamber 1, it slides downwards at an angle under the push of the spiral blades 3 and is dewatered through the filter screen at the bottom of the dewatering chamber 1. Excess water or liquid seeps out from the filter screen and falls into the water receiving tank 9 below.
[0031] The baffle 10 is to prevent water or liquid from spilling out from the rear of the water tank 9.
[0032] Furthermore, a first electric telescopic rod 15 is provided at the top of the dehydration chamber 1, and the rear side of the movable plate 4 is fixedly connected to the bottom end of the first electric telescopic rod 15.
[0033] When it is necessary to dehydrate or crush the material, the first electric telescopic rod 15 is driven to move the movable plate 4 forward or backward, so that it can move to the front of the discharge port for dehydration of the material, or move to the rear of the discharge port for feeding the material.
[0034] Furthermore, a second rotating shaft 20 is fixedly connected to one end of each of the crushing rollers 6, and a gear 21 is fixedly connected to the surface of each of the second rotating shafts 20. A placement box 18 is provided on the side wall of the crushing chamber 2, and a second motor 19 is arranged laterally in the inner cavity of the placement box 18. The output shaft of the second motor 19 is fixedly connected to one end of a second rotating shaft 20.
[0035] When it is necessary to crush materials, the second motor 19 is started. The output shaft of the motor starts to rotate, which drives the second rotating shaft 20 fixedly connected to it to rotate. As the second rotating shaft 20 rotates, the gear 21 fixed on its surface also starts to rotate. Since the gears 21 are meshed with each other, when one gear 21 rotates, the other gear 21 will also rotate accordingly, thereby driving the other crushing roller 6 to rotate. The two relatively rotating crushing rollers 6 clamp and crush the materials.
[0036] Furthermore, two second electric telescopic rods 17 are horizontally arranged on the top of the placement box 18, and the rear side of each scraper 8 is fixedly connected to one end of each second electric telescopic rod 17.
[0037] In this embodiment, when it is necessary to wipe the arc-shaped guide plate 7, the second electric telescopic rod 17 is activated. The electric telescopic rod begins to extend and retract, driving the scraper 8 fixedly connected to it to move. The sliding of the scraper 8 will remove the material accumulated on the surface of the arc-shaped guide plate 7, preventing material blockage or accumulation.
[0038] The working principle and usage process of this utility model are as follows: After the utility model is installed, the fecal material is poured into the dewatering chamber 1. The movable plate 4 is driven to move to the front of the discharge port. The rotating spiral blade 3 drives the material forward, thereby squeezing the material with the movable plate 4 to achieve solid-liquid separation. The water flows downward through the filter screen. After separation, the movable plate 4 is driven to move backward, so that the material flows into the crushing chamber 2. Then, it flows through the arc-shaped guide plate 7 to the space between the two crushing rollers 6. Then, the two crushing rollers 6 are started to crush the material. During the crushing process, the scraper 8 slides along the length of the arc-shaped guide plate 7, constantly wiping the surface of the guide plate. Finally, the material is discharged outward through the discharge pipe 16.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
