Description

Technical Field

[0001] This utility model belongs to the field of bamboo crushing technology, specifically relating to a bamboo pre-crushing device with a spiral propulsion structure. Background Technology

[0002] Bamboo crushing is a crucial step in bamboo processing and utilization. By crushing whole bamboo into bamboo chips, bamboo shreds, or bamboo powder of different specifications, the application value and economic efficiency of bamboo can be significantly improved. In current technology, bamboo is generally crushed by directly feeding it into the crushing mechanism. This results in a large load on the crushing mechanism during crushing, which can easily lead to reduced stability during use and even jamming. If the raw material size is smaller, the energy consumption required for equipment processing is lower, and the workload of power equipment such as motors is also reduced accordingly. Therefore, pre-crushing the bamboo before the crushing mechanism can reduce the workload of the subsequent crushing mechanism, thereby improving the continuous operation time and production efficiency of the equipment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figures 1 to 4As shown, a bamboo pre-crushing device with a spiral propulsion structure includes a housing 1. A cutting chamber 2 is fixedly connected to the top of the housing 1. A pressing chamber is fixedly connected to one side of the cutting chamber 2. A conveyor belt 3 is fixedly connected and passes through one side of the pressing chamber. A hydraulic cylinder 4 is fixedly connected to one side of the top of the pressing chamber. A pressing block 5 is fixedly connected to the output end of the hydraulic cylinder 4. A support guide platform 6 is fixedly connected to one side of the bottom wall of the pressing chamber. A first drive motor 7 is fixedly connected to the top of the surface of the cutting chamber 2. A cam 8 is fixedly connected to the output end of the first drive motor 7. Two positioning rods 9 are fixedly connected inside the cutting chamber 2. A return spring 10 is sleeved on the surface of the positioning rods 9. A blocking block is fixedly connected to the bottom end of the positioning rods 9. The surface of the positioning rod 9 slides through the lower pressure plate 11. A cutting blade 12 is fixedly connected to the middle of the bottom of the lower pressure plate 11. A conveying plate 13 is fixedly connected to the bottom end of one side of the inner wall of the cutting cavity 2. Seven drive motors are fixedly connected to the surface of the conveying plate 13. A conveying roller 14 is fixedly connected to the output end of the drive motor. A through hole is opened in the middle of the top of the box 1. The surface of the cutting cavity 2 is fixed and passes through the inside of the through hole. A conveying cavity 15 is fixedly connected to the top of the inner wall of the box 1. Two second drive motors 16 are fixedly connected to the top of the surface of the box 1. A spiral conveying blade 17 is fixedly connected to the output end of the second drive motor 16. A material discharge port 18 is opened on one side of the bottom wall of the conveying cavity 15.

[0024] The bamboo is pre-cut by the cutting cavity 2. The bamboo to be crushed is transported by the conveyor belt 3. The bamboo is pressed by the hydraulic cylinder 4 and the pressing block 5, flattening it from a cylindrical shape. The support guide table 6 provides support at the bottom of the bamboo during compression. The first drive motor 7 provides driving force for the rotation of the cam 8. The cam 8 causes the lower pressure plate 11 to be pressed downward. The positioning rod 9 is located on both sides of the inner wall of the cutting cavity 2, and grooves are provided at the corresponding positions to facilitate the placement of the positioning rod 9. The lower pressure plate 11 slides through the inside of the grooves. The return spring 10 is provided. This allows the lower pressure plate 11 to automatically reset after being pressed downwards, which in turn allows the cutting blade 12 to reset after descending, ensuring intermittent cutting of the bamboo. The arrangement of the conveying plate 13, conveying roller 14, and drive motor allows the cut bamboo to be conveyed. The arrangement of the conveying cavity 15 allows the spiral conveying blade 17 to rotate inside it. The two spiral conveying blades 17 rotate in opposite directions. The second drive motor 16 provides a certain driving force for the rotation of the spiral conveying blades 17. The spiral conveying blades 17 are variable diameter blades, which can realize radial shearing and conveying of bamboo. The surface of the spiral conveying blades 17 is coated with a wear-resistant alloy coating made of tungsten carbide to extend its service life. The discharge port 18 ensures that the bamboo is conveyed after being cut and falls downwards.

[0025] Example 2:

[0026] Please see Figure 1 and Figure 5 As shown, a crushing chamber 19 is fixedly connected to the middle of the inner wall of the box 1, and a bearing plate is fixedly connected to the top of one side of the surface of the box 1. A third drive motor 20 is fixedly connected to the inner wall of the bearing plate, and a first drive shaft is fixedly connected to the output end of the third drive motor 20. A first gear 21 is fixedly connected to one side of the surface of the first drive shaft. The crushing chamber 19 allows the bamboo to be crushed again. The third drive motor 20 provides a certain driving force for the rotation of the first drive shaft and the first gear 21. There are two first drive shafts, which are parallel to each other and have the same structure.

[0027] The surface of the first gear 21 is meshed with the second gear 22, and the surface of the first drive shaft is fixedly connected to the crushing roller 23. The first pulley 24 is fixedly connected to one side of the surface of the first drive shaft. The rotation of the first gear 21 drives the second gear 22 to rotate, so that the crushing rollers 23 on the two first drive shafts rotate towards each other, which facilitates the crushing and pulverizing of bamboo.

[0028] The surface of the first pulley 24 is connected to the first transmission belt 25, and two second transmission shafts 26 are rotatably arranged inside the housing 1. The rotation of the first pulley 24 drives the first transmission belt 25 to rotate. The two second transmission shafts 26 are located below the first transmission shaft and are parallel to each other. Crushing rollers 23 are also fixedly connected to the second transmission shafts 26, two on the top and two on the bottom, to achieve the purpose of secondary crushing.

[0029] A second pulley is fixedly connected to one side of the surface of the second drive shaft 26, and the inner sidewall of the first drive belt 25 is connected to the surface of the second pulley. After the first drive shaft rotates, the first pulley 24 rotates, and then drives the second pulley through the first drive belt 25, causing both second drive shafts 26 to rotate.

[0030] A discharge port is provided at the bottom of one side of the box body 1, and a guide plate 27 is fixedly connected to the inner wall of the discharge port. The opening of the discharge port makes it easy for the crushed bamboo to be discharged to the outside, and the guide plate 27 facilitates the guidance of the crushed bamboo to the corresponding position.

[0031] A control panel is fixedly connected to the top of the surface of the housing 1, and the control panel is electrically connected to the conveyor belt 3, the hydraulic cylinder 4, the first drive motor 7, the second drive motor 16, the third drive motor 20 and the drive motor respectively.

[0032] The working principle of this utility model is as follows: The operator first transports the bamboo to be crushed into the extrusion chamber via conveyor belt 3. Simultaneously, the operator controls the hydraulic cylinder 4 to start, and the output end of the hydraulic cylinder 4 intermittently drives the extrusion block 5 downwards, causing the bamboo to be intermittently extruded. Some older and fragile bamboo is flattened and then moves continuously to the right, eventually reaching the cutting chamber 2. Some newer bamboo, after being flattened, bends downwards at one end due to its own toughness and then moves below the cutting blade 12. The operator controls the first drive motor 7 and the drive motor to operate, causing the output end of the first drive motor 7 to drive the cam 8 to rotate, which then causes the lower pressure plate 11 to move downwards. This causes the cutting blade 12 to continuously descend, intermittently cutting the bamboo. During cutting, the bamboo passes above the conveyor plate 13, which also provides some support to its bottom. Then, the drive motor drives the conveyor roller 14 to transport the cut bamboo to the right. The cut bamboo continuously falls downwards and eventually enters the conveying chamber 15. At this point, the operator... Two second drive motors 16 are controlled to operate. The output of the second drive motors 16 drives the spiral conveyor blades 17 to rotate, which axially compresses and conveys the cut bamboo material that falls into the blades. Finally, the bamboo material falls downward through the discharge port 18 and enters the crushing chamber 19. At this time, the operator controls the third drive motor 20 to operate. The output of the third drive motor 20 drives the first drive shaft to rotate, and then the first gear 21 rotates. The rotation of the first gear 21 drives the second gear 22 that meshes with it to rotate, which in turn causes the two first drive shafts to rotate in opposite directions. At the same time, the two crushing rollers 23 rotate in opposite directions, which crushes the bamboo material that has fallen into the crushing chamber 19. The rotation of the first drive shaft drives the first pulley 24 to rotate, and then drives the second pulley on the second drive shaft 26 to rotate through the first drive belt 25. This causes the two second drive shafts 26 below to rotate in opposite directions, and at the same time, the crushing rollers 23 above them also rotate in opposite directions, achieving secondary crushing of the bamboo material, improving the crushing effect of the bamboo material, and making it easier to meet the requirements of subsequent processing.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
