Description
Technical Field
[0001] The utility model relates to the field of crushers, in particular to a double-shaft garbage crushing device. Background Art
[0002] Waste recycling and treatment requires centralized crushing. Currently, the common crushing equipment is a double-shaft crusher, and its main structure is two juxtaposed rollers. Garbage is crushed through extrusion and tearing. This kind of equipment requires the rollers to have high strength and a large crushing power to effectively crush all the garbage. However, the types of garbage actually crushed are numerous, and often mixed with items of large volume and high hardness, which cannot be effectively crushed. At this time, it will get stuck between the rollers, resulting in the subsequent garbage not being able to be crushed, affecting the efficiency. Therefore, how to avoid the influence of large-volume uncrushable garbage on the crushing efficiency is the problem to be solved in this solution. Content of the Utility Model
[0003] To solve the above technical problems, the utility model provides a double-shaft garbage crushing device, which can allow large-volume garbage to pass through the rollers without being completely crushed and can collect it separately.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a double-shaft garbage crushing device, including a crushing bin;
[0005] The crushing bin includes a material bin section, a crushing section and an aggregate section from top to bottom; a garbage bin is arranged in the material bin section;
[0006] A fixed roller and a moving roller are arranged in parallel in the crushing section. The gap between the fixed roller and the moving roller is a feeding port. The fixed roller is driven by a motor. The two ends of the moving roller are rotatably fitted to sliding blocks, and the sliding blocks are slidably fitted transversely relative to the side wall of the crushing bin. An elastic member is arranged between the sliding blocks and the crushing bin, and the elastic member pushes the moving roller towards the fixed roller;
[0007] A guide plate is arranged below the fixed roller. One end of the guide plate is hinged to the side wall of the crushing bin. The two ends of a connecting rod are respectively hinged to the sliding block and the guide plate. A large-material discharge channel is arranged below the moving roller. When the sliding block slides towards the side away from the fixed roller, the connecting rod pulls the other end of the guide plate to swing and dock to the feeding port of the discharge channel.
[0008] When in use, the elastic member can push the moving roller towards the fixed roller so that the two approach each other. The garbage to be shredded passes through the relative rotation and extrusion of the fixed roller and the moving roller and is shredded. The shredded garbage falls normally downward from the feeding port. If there is large-volume garbage that cannot be shredded, since it has not been shredded, its volume remains relatively large. The large-volume garbage will push the moving roller, and the moving roller and the sliding block overcome the elastic force of the elastic member, and the gap between the moving roller and the fixed roller will become larger, so that the large-volume garbage can pass downward smoothly. At the same time as the moving roller and the fixed roller are separated, the moving roller will pull the guide plate to swing through the connecting rod. After swinging, the guide plate will dock with the feeding port of the discharge channel, that is, the falling large-volume garbage will slide to the discharge channel through the guide plate, thereby achieving the effect of separately collecting the shredded and unshredded garbage and avoiding piling them together.
[0009] Preferably, the elastic member is a hydraulic spring. The hydraulic spring recovers more slowly, which can ensure that when the large-volume garbage falls downward, the guide plate is docked with the discharge channel and the large-volume garbage smoothly falls into the discharge channel.
[0010] Preferably, swing arms are respectively arranged upward on both sides of the guide plate, and the upper ends of the swing arms are hinged to the side wall of the crushing bin. The swing arms can better pull the guide plate to swing.
[0011] Preferably, the hinge at the upper end of the swing arm is concentric with the fixed roller. So that during the swinging process of the guide plate, the distance from the fixed roller remains the same, avoiding too small or too large a distance.
[0012] Preferably, a cross plate is arranged on the inner wall of the crushing section, and the cross plate is provided with a slide rail adapted to the sliding block. The cross plate can better arrange the fixed roller and the moving roller, and the distance between the cross plate and the crushing bin is used to arrange structures such as the connecting rods and swing arms on both sides.
[0013] Preferably, the connecting rod and the swing arm are located between the cross plate and the crushing bin. The setting is more reasonable and it is more convenient to arrange the fixed roller and the moving roller.
[0014] Preferably, the guide plate is provided with a plurality of filter holes. Facilitating the filtration of small-volume garbage.
[0015] Preferably, a feeding plate is arranged inward between the material bin section and the crushing section. The inner end of the feeding plate corresponds to the space between the fixed roller and the moving roller, and the inner end of the feeding plate is inclined downward. Facilitating the centralized delivery of garbage between the fixed roller and the moving roller.
[0016] Preferably, crushing knives are respectively arranged on the outer walls of the fixed roller and the moving roller. Facilitating the improvement of the crushing effect.
[0017] Preferably, the moving roller is driven by a motor, and the moving roller and the fixed roller rotate downward relatively. Both rollers provide the power of rotation, which can improve the tearing effect.
[0018] Advantages of the present utility model:
[0019] In this solution, by setting a moving roller pushed by an elastic member, large-volume garbage that cannot be crushed can pass through smoothly, avoiding affecting subsequent crushing work and improving the crushing efficiency. Through the connection of a connecting rod and a material guiding plate, the large-volume garbage that has not been crushed can be sent to the discharge channel, realizing the separate collection of large-volume garbage and normally crushed garbage.

Specific implementation manners
[0023] In order to deepen the understanding of the present utility model, the following will further describe the present utility model in detail with reference to the drawings and embodiments. This embodiment is only used to explain the present utility model and does not limit the protection scope of the present utility model.
[0024] Embodiment
[0025] As Figure 1As shown in the figure, a double-shaft garbage crushing device includes a crushing bin. The crushing bin includes a material bin section 1, a crushing section 2, and an aggregate section 3 from top to bottom. A garbage bin is provided in the material bin section 1. In the crushing section 2, a fixed roller 4 and a moving roller 5 are arranged in parallel. The space between the fixed roller 4 and the moving roller 5 is the feeding port. The fixed roller 4 is driven by a motor. The two ends of the moving roller 5 are rotatably fitted to sliding blocks 11. The sliding blocks 11 are slidably fitted horizontally relative to the side wall of the crushing bin. An elastic member 12 is provided between the sliding blocks 11 and the crushing bin. The elastic member 12 pushes the moving roller 5 towards the fixed roller 4. A guide plate 6 is provided below the fixed roller 4. One end of the guide plate 6 is hinged to the side wall of the crushing bin. The two ends of a connecting rod 8 are respectively hinged to the sliding block 11 and the guide plate 6. A large-piece discharge channel 13 is provided below the moving roller 5. When the sliding block 11 slides away from the fixed roller 4, the connecting rod 8 pulls the other end of the guide plate 6 to swing and dock with the feeding port of the discharge channel 13.
[0026] During use, the elastic member 12 can push the moving roller 5 towards the fixed roller 4 so that the two are close to each other. The garbage to be crushed is squeezed and shredded by the relative rotation of the fixed roller 4 and the moving roller 5, and the shredded garbage bins normally fall downward from the feeding port. If there is large-volume garbage that cannot be crushed and shredded, since it is not shredded, its volume remains relatively large. The large-volume garbage will push the moving roller 5, and the moving roller 5 and the sliding block 11 overcome the elastic force of the elastic member 12, and the gap between the moving roller 5 and the fixed roller 4 will become larger, so that the large-volume garbage can smoothly pass downward. At the same time as the moving roller 5 and the fixed roller 4 are separated, the moving roller 5 will pull the guide plate 6 to swing through the connecting rod 8. After swinging, the guide plate 6 will dock with the feeding port of the discharge channel 13, that is, the falling large-volume garbage will slide to the discharge channel 13 through the guide plate 6, thereby achieving the effect of separately collecting the crushed and uncrushed garbage and avoiding piling them together.
[0027] The elastic member 12 is a hydraulic spring. The hydraulic spring recovers more slowly, which can ensure that when the large-volume garbage falls downward, the guide plate 6 is docked with the discharge channel 13, and the large-volume garbage smoothly falls into the discharge channel 13.
[0028] Swing arms 7 are respectively provided upward on both sides of the guide plate 6. The upper ends of the swing arms 7 are hinged to the side wall of the crushing bin. The swing arms 7 can better pull the guide plate 6 to swing.
[0029] The hinge at the upper end of the swing arm 7 is concentric with the fixed roller 4. So that during the swinging process of the guide plate 6, the distance from the fixed roller 4 remains the same, avoiding too small or too large a distance.
[0030] The inner wall of the crushing section 2 is provided with a cross plate 9, and the cross plate 9 is provided with a slide rail adapted to the sliding block 11. The cross plate 9 can be used to better arrange the fixed rotating roller 4 and the moving rotating roller 5, and the distance between the cross plate 9 and the crushing bin is used to arrange structures such as the connecting rods 8 and swing arms 7 on both sides.
[0031] The connecting rod 8 and the swing arm 7 are located between the cross plate 9 and the crushing bin. The setting is more reasonable and it is more convenient to arrange the fixed rotating roller 4 and the moving rotating roller 5.
[0032] The guide plate 6 is provided with a number of filter holes. It is convenient to filter out small-volume garbage.
[0033] An inclined feeding plate 10 is arranged inward between the bin section 1 and the crushing section 2. The inner end of the feeding plate 10 corresponds to the space between the fixed rotating roller 4 and the moving rotating roller 5, and the inner end of the feeding plate 10 is inclined downward. It is convenient to concentrate the garbage and send it between the fixed rotating roller 4 and the moving rotating roller 5.
[0034] The outer walls of the fixed rotating roller 4 and the moving rotating roller 5 are respectively provided with crushing knives. It is convenient to improve the crushing effect.
[0035] The moving rotating roller 5 is driven by a motor, and the moving rotating roller 5 and the fixed rotating roller 4 rotate relatively downward. Both rotating rollers provide the power of rotation, which can improve the tearing effect.
[0036] The beneficial effects of the present utility model:
[0037] In this solution, by setting the moving rotating roller 5 pushed by the elastic member 12, large-volume garbage that cannot be crushed can pass through smoothly, avoiding affecting subsequent crushing work and improving the crushing efficiency. Through the connection of the connecting rod 8 and the guide plate 6, large-volume garbage that has not been crushed can be sent to the discharge channel 13, realizing the separate collection of large-volume garbage and normally crushed garbage.
[0038] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0039] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent shall be subject to the appended claims.
