Description
Technical Field
[0001] This utility model relates to the technical field of crushers for recycling plastic waste that are easy to feed materials into, specifically a crusher for recycling plastic waste that is easy to feed materials into. Background Technology
[0002] Crushers are primarily used to break large materials into smaller particles or powder to meet various needs in subsequent processing, transportation, and use. Their main applications include: Building material production: For example, in the production of cement, concrete, sand, and other building materials, limestone, granite, basalt, and other rock raw materials need to be crushed. Hammer crushers and impact crushers can be used to crush these raw materials into suitable particle sizes, producing products that meet the quality standards for construction sand and gravel, satisfying the large-scale demand for various aggregates in construction projects; Environmental protection industry: Crushers play a crucial role in the treatment of solid waste (such as construction waste, plastic waste, and electronic waste). For example, for concrete blocks and bricks in construction waste, jaw crushers and impact crushers can be used to crush them, and then the crushed materials are screened and reprocessed to produce recycled building materials; For plastic waste recycling, specialized plastic crushers are used to crush plastic waste into small particles, facilitating subsequent washing, granulation, and other recycling processes.
[0003] However, some existing plastic waste recycling crushers are not convenient for feeding materials, which may not only increase the difficulty of manual operation and the labor intensity of workers, but also create more safety hazards.
[0004] Therefore, those skilled in the art have provided a crusher for recycling plastic waste that is easy to feed materials into, in order to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to provide a plastic waste recycling crusher that is easy to feed materials into, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A crusher for recycling plastic waste that facilitates material feeding includes a lower housing; several lower positioning blocks are fixedly connected to the upper ends of the front and rear sides of the lower housing; a crushing box slide groove is slotted at the front and rear ends of the upper surface of the lower housing; a crushing box body is slidably connected to the outer side of the crushing box slide groove; several upper positioning blocks are fixedly connected to the lower ends of the front and rear sides of the crushing box body; fixing bolts are threadedly connected to the internal lower and upper positioning blocks; a shielding frame is fixedly connected to the upper side of the crushing box body; several height adjustment grooves are slotted at the front and rear sides of the outer surface of the shielding frame; a feeding hopper is provided on the upper side of the shielding frame; several height adjustment blocks are provided at the lower ends of the front and rear sides of the feeding hopper.
[0008] As a further embodiment of this utility model, a motor mounting bracket is fixedly connected to the front right side of the crushing box body, and a drive motor is fixedly connected to the upper side of the motor mounting bracket.
[0009] As a further embodiment of this utility model, the output end of the drive motor is fixedly connected to a rotating shaft, and a front sprocket is fixedly connected to the outer side of the rotating shaft.
[0010] As a further embodiment of this utility model, a chain is engaged on the outer side of the front sprocket, and a rear sprocket is engaged on the inner rear side of the chain.
[0011] As a further embodiment of this utility model, a blade fixing shaft is fixedly connected to the left side of the rotating shaft, and a number of crushing blades are fixedly connected to the outside of the blade fixing shaft.
[0012] As a further embodiment of this utility model, the lower box has an internal slot with a lower discharge port, and several placement bases are fixedly connected to the front and rear ends of the lower side of the lower box.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The height of the feeding hopper can be adjusted using the height adjustment block, and the horizontal position of the feeding hopper can be adjusted using the crushing box chute. When manual feeding is used, the height of the feeding hopper can be lowered to a suitable position, allowing operators to easily put plastic waste into it without excessive lifting or bending. For example, at some small plastic waste recycling sites, operators may need to frequently manually put the collected plastic waste into the crushing box. If the feeding hopper is too high, prolonged lifting will increase labor intensity, easily lead to operator fatigue, and affect work efficiency. The height-adjustable feeding hopper can be lowered to an ergonomic height, making the feeding process easier and more convenient, reducing the physical exertion of operators. Moreover, when processing large amounts of plastic waste, mechanical auxiliary equipment such as conveyor belts and hoisting equipment are often used for feeding. At this point, the height of the feeding hopper can be raised to better match the discharge end of the conveyor belt or the lowering position of the hoisting equipment. This allows materials to enter the feeding hopper directly and smoothly from these auxiliary devices, avoiding spillage and accumulation caused by unsuitable height differences. This improves the efficiency and accuracy of mechanically assisted feeding, ensuring that materials can quickly and orderly enter the crushing chamber for subsequent processing. Furthermore, plastic waste varies in size, ranging from small plastic bottle caps and fragments to larger plastic pipes and sheets. The adjustable feeding hopper can be moved flexibly according to the size of the materials, allowing its opening to better align with larger items. This facilitates accurate feeding of these large pieces of plastic waste and avoids situations where large items cannot be placed due to a fixed hopper position. Simultaneously, for smaller materials, the hopper position can be adjusted to place them in a more suitable collection area, facilitating centralized feeding and improving overall feeding efficiency. In addition, adjusting the height and horizontal position of the feeding hopper allows the feeding operation to be conducted from a safer and more easily observable location. For example, by adjusting the feeding hopper to a location where the operator has a clear view and can operate it easily, the operator can better control the feeding process, promptly detect any abnormalities that occur during material feeding (such as material jamming or blockage), and avoid unsafe operating postures (such as overstretching the body or standing at an unstable height) due to an unreasonable location, thus reducing the risk of accidents during the feeding process and ensuring the personal safety of the operator.

Detailed Implementation
[0020] Please see Figures 1-4 In this embodiment of the present invention, a crusher for recycling plastic waste that facilitates material feeding includes a lower housing 1; several lower positioning blocks 2 are fixedly connected to the upper ends of the front and rear sides of the lower housing 1; the upper surface of the lower housing 1 has grooves at both the front and rear ends of the upper side of the lower housing 1 with crushing box slide grooves 3; a crushing box body 4 is slidably connected to the outer side of the crushing box slide grooves 3; several upper positioning blocks 5 are fixedly connected to the lower ends of the front and rear sides of the crushing box body 4; the lower positioning blocks 2 and the upper positioning blocks 5 are internally threaded with fixing bolts 6; a shielding frame 7 is fixedly connected to the upper side of the crushing box body 4; several height adjustment grooves 8 are grooved on the front and rear sides of the outer surface of the shielding frame 7; a feeding hopper 9 is provided on the upper side of the shielding frame 7; and the lower ends of the feeding hopper 9 are located at the lower ends of the front and rear sides of the upper housing 1. The end is provided with several height adjustment blocks 10; a motor fixing frame 11 is fixedly connected to the front right side of the crushing box body 4, and a drive motor 12 is fixedly connected to the upper side of the motor fixing frame 11; a rotating shaft 13 is fixedly connected to the output end of the drive motor 12, and a front sprocket 14 is fixedly connected to the outer side of the rotating shaft 13; a chain 15 is engaged on the outer side of the front sprocket 14, and a rear sprocket 16 is engaged on the inner rear side of the chain 15; a blade fixing shaft 17 is fixedly connected to the left side of the rotating shaft 13, and several crushing blades 18 are fixedly connected to the outer side of the blade fixing shaft 17; the lower box body 1 has a slotted lower discharge port 19, and several placement bases 20 are fixedly connected to the front and rear ends of the lower side of the lower box body 1.
[0021] The working principle of this utility model is as follows: When plastic waste needs to be crushed, the worker can adjust the height of the feeding hopper 9 according to the size of the plastic waste to be processed and the feeding method, through the height adjustment groove 8 and the height adjustment block 10. Specifically, by pressing the height adjustment block 10 until it is completely separated from the height adjustment groove 8, the fixing between the shield 7 and the feeding hopper 9 is released. Then, the feeding hopper 9 can be moved up and down until it reaches the appropriate position. After stopping, the height adjustment block 10, under the action of its internal elastic component, will precisely engage with the height adjustment groove 8 on the other side, thus fixing the height-adjusted feeding hopper 9. This ensures that plastic waste can be better fed into the feeding hopper 9. If further adjustment of the feeding hopper 9 is needed... When the material is in a horizontal position, simply turn the fixing bolt 6 completely away from the lower positioning block 2 and the upper positioning block 5. Then, the fixing between the lower box 1 and the feeding hopper 9 can be released. Then, the feeding hopper 9 and the crushing box body 4 can be moved horizontally along the crushing box slide 3. After moving to a suitable position, stop moving and then turn the fixing bolt 6 completely into the corresponding lower positioning block 2 and upper positioning block 5. At this time, the fixing of the feeding hopper 9 after horizontal adjustment is completed. The height of the feeding hopper 9 can be adjusted by the height adjustment block 10, and the horizontal position of the feeding hopper 9 can be adjusted by the crushing box slide 3. When manual feeding is used, the height of the feeding hopper 9 can be lowered to a suitable position so that the operator can easily put plastic waste into it without excessive lifting of the hand or bending over. For example, at some small plastic waste recycling sites, operators may need to frequently and manually feed the collected plastic waste into the crushing bin 4. If the feeding hopper 9 is too high, prolonged lifting for feeding will increase labor intensity, easily leading to operator fatigue and affecting work efficiency. An adjustable-height feeding hopper 9 can be lowered to an ergonomic height, making the feeding process easier and more convenient, reducing the physical exertion of operators. Furthermore, when processing large amounts of plastic waste, mechanical auxiliary equipment such as conveyor belts and hoisting equipment are often used for feeding. In this case, the height of the feeding hopper 9 can be raised to better match the discharge end of the conveyor belt or the lowering position of the hoisting equipment, allowing materials to enter the feeding hopper 9 directly and smoothly from these auxiliary devices. This avoids material spillage and accumulation due to unsuitable height differences, improving the efficiency and accuracy of mechanical auxiliary feeding and ensuring that materials can quickly and orderly enter the crushing bin 4 for subsequent processing. Moreover, plastic waste varies in size, ranging from small plastic bottle caps and fragments to larger plastic pipes and sheets. The adjustable horizontal feeding hopper 9 can be moved flexibly according to the size of the material, so that its opening can be better aligned with larger materials, making it easier for operators to accurately put these large plastic wastes in, and avoiding the situation where it is difficult to put in large materials due to the fixed position of the feeding hopper 9.Meanwhile, for smaller materials, the position of the feeding hopper 9 can be adjusted to place it in a more suitable collection area, making it easier to feed the material centrally and improving the overall feeding efficiency. In addition, by adjusting the height and horizontal position of the feeding hopper 9, the feeding operation can be set in a safer and more easily observable location. For example, by adjusting the feeding hopper 9 to a location with a clear view and convenient operation for the operator, the operator can better control the feeding process, promptly detect any abnormalities that occur during material feeding (such as material jamming or blockage), and avoid unsafe operating postures (such as overstretching the body or standing at an unstable height) due to unreasonable positioning. This reduces the risk of accidents during feeding and ensures the personal safety of the operator. Then, the plastic waste is simply sorted to remove impurities such as metal and stones. The material is then fed into the feeding hopper 9 at the adjusted height, and the material will automatically slide into the crushing box body 4 under gravity. The drive motor 12 is then started, and the power is transmitted to the front sprocket 14 through the rotating shaft 13, and then to the rear sprocket 16 through the chain 15. Finally, the blade fixing shafts 17 on both the front and rear sides rotate, and the blade fixing shafts 17 on both the front and rear sides drive the crushing blades 18 on their surfaces to rotate. The plastic waste entering the crushing box body 4 can then be sheared and crushed. The crushed plastic fragments are then discharged through the lower discharge port 19 in the lower box 1.
