Detailed Implementation

[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 1-4 This utility model provides a technical solution: a biological organic fertilizer raw material crusher includes a feeding conveyor belt 3, the feeding conveyor belt 3 includes a frame 31 and a conveyor belt 32, a mounting frame 1 is provided at the rear end of the feeding conveyor belt 3, and guide plates 9 extending to the rear end of the conveyor belt 32 are fixedly connected to both sides of the inner wall of the mounting frame 1. A cutting component for cutting materials and a driving component for driving the cutting component to move up and down are provided on the mounting frame 1 and above the guide plate 9. A crushing chamber 5 is provided on the rear side of the guide plate 9. Two staggered crushing rollers 8 are provided in the inner cavity of the crushing chamber 5. A discharge conveyor belt 7 that is inclined from bottom to top along the conveying direction is provided below the crushing chamber 5.

[0020] A pressure roller 4 is provided on the upper surface of the rear end of the frame 31. Rotatable limiting cylinders 2 and a transmission assembly for driving the two limiting cylinders 2 to rotate are symmetrically arranged on the frame 31 and on the left and right sides in front of the pressure roller 4. The limiting cylinders 2 are transversely arranged tapered rollers with a narrow front end and a wide rear end. The bottom edge of the limiting cylinder 2 is parallel to the upper surface of the conveyor belt 32. The two limiting cylinders 2 rotate in opposite directions and the gap between the two limiting cylinders 2 gradually narrows from front to back.

[0021] In this embodiment, the mounting frame 1 can be N-shaped, and the guide plate 9 can be installed between the inner walls of both sides of the mounting frame 1. The front end of the guide plate 9 is close to the rear end of the conveyor belt 32 but does not contact it. The rear end of the guide plate 9 should extend above the space between the two crushing rollers 8 to facilitate the material falling from the guide plate 9 and being crushed directly. After crushing, the material falls to the front end of the discharge conveyor belt 7, which transports the crushed material to the rear for unified collection. The limiting cylinder 2 should be placed at an angle, with its bottom surface parallel to the conveyor belt 32. The two limiting cylinders 2 are reversed. The material is centered by rotating the material in the opposite direction, while preventing it from rolling out from the bottom of the limiting cylinder 2. The pressing roller 4 limits the material to a certain height, and the front end of the material is pressed and continues to move along the conveying direction to the cutting process under the conveyor belt 32, which provides some assistance to the subsequent cutting process. A transmission box is set on one side of the crushing chamber 5. A third motor drives a crushing roller 8 to rotate in the transmission box. A sprocket is installed on the shaft of each of the two crushing rollers 8. The two sprockets are driven by a chain, which can make the other crushing roller 8 rotate in the opposite direction at the same time.

[0022] Furthermore, the transmission assembly includes two pulleys 21, two gears 22, and a first motor 6. A mounting base is fixedly connected to the frame 31, and a first motor 6 for driving a limiting cylinder 2 to rotate is fixedly connected to the top of the mounting base. A mounting plate 20 is fixedly connected to the mounting base, and a mounting shaft is rotatably provided on the mounting plate 20. One gear 22 and one pulley 21 are fixedly mounted on the mounting shaft. Another pulley 21 is fixedly mounted on the shaft of one limiting cylinder 2, and another gear 22 is fixedly mounted on the shaft of another limiting cylinder 2. The two pulleys 21 are connected by belt drive, and the two gears 22 mesh with each other.

[0023] In this embodiment, while the first motor 6 drives a limiting cylinder 2 to rotate, the pulley on it will rotate synchronously. The pulley 21 on the mounting plate that is connected to it will rotate synchronously. The gear 22 coaxial with the pulley 21 will rotate in the same direction. At the same time, the other gear 22 that is meshed with it will rotate in the opposite direction and drive another limiting cylinder 2 coaxial with it to rotate in the same direction.

[0024] Furthermore, the drive assembly includes a turntable 11, a connecting rod 12, a connecting shaft 13, and a second motor 18. The turntable 11 is rotatably disposed on the upper part of the inner side of the mounting frame 1. A second motor 18 for driving the turntable 11 to rotate is disposed on one side of the outer surface of the mounting frame 1. One end of the connecting shaft 13 is eccentrically fixedly connected to the outer surface of the turntable 11. A bushing is rotatably fitted on the outer surface of the connecting shaft 13. The top end of the connecting rod 12 is fixedly connected to the bottom end of the bushing.

[0025] In this embodiment, the second motor 18 drives the turntable 11 to rotate. The connecting shaft 13 is eccentrically set on the outer surface of the turntable 11, so both ends will move along a circular trajectory. The other end of the connecting shaft 13 is fixedly connected to the outer surface of the same turntable 11 at the same position, which improves the stability of the connecting shaft 13 when rotating. Since the bushing is rotatably connected to the outer surface of the connecting shaft 13, the connecting rod 12 will always remain vertically downward.

[0026] Furthermore, the cutting assembly includes a blade holder 14, a cutting blade 15, two guide rails 17, and two sliders 16. The top of the blade holder 14 is hinged to the bottom of the two connecting rods 12 respectively. The cutting blade 15 is fixedly connected to the bottom of the blade holder 14. The two guide rails 17 are fixedly connected to both sides of the inner wall of the mounting bracket 1 respectively. The two sliders 16 are slidably connected to one guide rail 17 respectively. The two ends of the blade holder 14 are fixedly connected to the two sliders 16 respectively.

[0027] In this embodiment, such as Figure 4 As shown, the two ends of the blade holder 14 are fixedly connected to a slider 16, and the slider 16 moves vertically on the guide rail 17. Therefore, the cutting blade 15 and the blade holder 14 are limited to moving only up and down.

[0028] Furthermore, a through groove adapted to the cutting blade 15 is vertically opened on the guide plate 9 and located directly below the cutting blade 15, and a pressure frame 10 is provided on the upper surface of the guide plate 9 and located behind the through groove.

[0029] In this embodiment, when the cutting blade 15 contacts the material surface, the rear end of the material is pressed down by the pressure frame 10, thereby preventing one end of the material from lifting up during the cutting operation.

[0030] Furthermore, a baffle 19 is provided on the top of the crushing chamber 5.

[0031] In this embodiment, during the crushing operation, the baffle 19 will block the material fragments to prevent them from splashing around the machine.

[0032] The working principle and usage process of this utility model are as follows: After the utility model is installed, the staff places the material at the front end of the feed conveyor belt 3. The material moves along the conveying direction to the space between the two limiting cylinders 2. Then, the first motor 6 starts, and under the action of the transmission component, the two limiting cylinders 2 rotate in opposite directions to center the material. The material then falls from the rear end of the feed conveyor belt 3 to the front end of the guide plate 9. At this time, the pressing roller 4 presses the front end of the material, and the pressing frame 10 presses the rear end of the material. The second motor 18 drives the cutting blade 15 to cut the material. After that, the cutting blade 15 is lifted, and the material continues to move along the conveying direction, falling from the rear end of the guide plate 9 into the crushing chamber 5. After being crushed between the two rotating crushing rollers 8, the material falls to the front end of the discharge conveyor belt 7. Finally, the discharge conveyor belt 7 carries the material to the rear side for unified collection.

[0033] 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.
