Description

Technical Field

[0001] This utility model relates to the field of garbage bin technology, specifically a garbage sorting bin with a solid waste crushing structure. Background Technology

[0002] With rapid urbanization and population growth, the amount of household waste continues to rise, posing numerous challenges to traditional waste sorting bins in handling solid waste. In particular, the direct disposal of bulky or hard waste (such as plastic bottles, packaging boxes, and kitchen scraps) often occupies a significant amount of space, reducing the bin's storage efficiency and increasing collection frequency and costs. Furthermore, uncrushed waste may lead to incomplete sorting, affecting subsequent recycling and processing.

[0003] Most existing waste sorting bins only have simple disposal and storage functions. The few equipped with crushing devices suffer from complex structures, high energy consumption, or excessive noise, making them unsuitable for widespread application in communities and public places. Therefore, there is an urgent need to develop a waste sorting bin with an integrated, highly efficient crushing structure. This would reduce waste volume through mechanical means, improve sorting efficiency, and simultaneously ensure energy conservation, environmental protection, and user-friendliness, thus meeting the demands of modern waste management.

[0004] According to authorization announcement number CN 22269494 U, a crushing device for treating municipal solid waste is disclosed, including an operating platform body. A crushing chamber is fixedly installed on the upper surface of the operating platform body. A compaction frame is fixedly connected to one side of the crushing chamber. A crushing auxiliary component is installed inside the crushing chamber, and a compaction component is installed inside the compaction frame. A double door is rotatably connected to the top of the crushing chamber via a hinge. The crushing auxiliary component includes a support plate fixedly installed on one side of the crushing chamber. A drive motor is fixedly installed on the upper surface of the support plate, and a drive wheel is fixedly installed at the input end of the drive motor. Crushing rollers are symmetrically rotatably connected inside the crushing chamber.

[0005] The aforementioned patent can only crush solid waste during use, but it cannot adjust the size of the crushed waste, which affects the efficiency and quality of subsequent waste recycling. Therefore, there is a need for a waste sorting bin with a solid waste crushing structure. Utility Model Content

[0006] The purpose of this utility model is to provide a waste sorting bin with a solid waste crushing structure. By setting an adjustment component to drive the crushing component to move, the distance between the two crushing components can be adjusted, thereby achieving the adjustment of the size of the crushed waste, so as to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A waste sorting bin with a solid waste crushing structure includes a waste bin for recycling waste. The inside of the waste bin is equipped with a support frame for support. Two sets of crushing components for crushing waste are arranged in parallel in the middle of the support frame. Sliding grooves are symmetrically opened on both sides of the support frame. Adjustment components for pushing the crushing components to slide are arranged inside the sliding grooves.

[0009] The adjustment assembly includes a U-shaped frame disposed inside the chute and an electric push rod for pushing the U-shaped frame to slide. Limiting blocks for limiting the position of the crushing components are respectively installed at both ends of the U-shaped frame. One set of the crushing components is disposed in the middle of the two sets of limiting blocks. The adjustment assembly drives the corresponding crushing components to move along the chute through the U-shaped frame. The other set of the crushing components is installed in the middle of the support frame.

[0010] Preferably, the electric push rod is mounted on the side of the support frame via a support block, and the output end of the electric push rod is connected to the U-shaped frame by bolts.

[0011] Preferably, the crushing assembly includes a servo motor disposed in the middle of the support frame for driving the rotating shaft to rotate, and a crushing roller for crushing waste is installed in the middle of the rotating shaft.

[0012] Preferably, the surface of the crushing roller is equipped with several sets of crushing wheels, and the crushing wheels on the surfaces of two sets of crushing rollers are arranged alternately.

[0013] Preferably, the support frame is equipped with a recycling bin for recycling crushed waste, and the inlet of the recycling bin is set to correspond to the crushing component.

[0014] Preferably, the lower surface inside the trash can is fitted with a mounting base for sliding the recycling bin, and the recycling bin is installed inside the mounting base.

[0015] Preferably, the inside of the trash can is provided with a sliding groove, and the two sides of the mounting base are equipped with movable blocks that match the sliding groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When the size of the crushed waste needs to be adjusted, the adjustment component is activated, and the electric push rod begins to work, pushing the U-shaped frame to slide smoothly within the chute. The crushing component in the middle of the limit blocks at both ends of the U-shaped frame moves synchronously with the U-shaped frame, cooperating with another set of crushing components fixedly installed on the support frame. By adjusting the crushing components through the adjustment component, the distance between the two sets of crushing components is changed, thereby adjusting the degree of waste crushing, ensuring the efficiency and quality of subsequent waste recycling, and increasing the overall practicality of the waste bin.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] This utility model provides: a waste sorting bin with a solid waste crushing structure, such as... Figures 1-5 As shown, the device includes a waste bin 1 for recycling waste. Inside the waste bin 1 is a support frame 2 for support. Two sets of crushing components 3 for crushing waste are arranged parallel to each other in the middle of the support frame 2. Sliding grooves 4 are symmetrically arranged on both sides of the support frame 2. Adjustment components 5 are installed inside the grooves 4 to push the crushing components 3 to slide. The support frame 2 inside the waste bin 1 provides stable support for the crushing components 3 and adjustment components 5, effectively enhancing the overall structural strength and ensuring that the equipment will not shake or shift due to the impact of waste input or vibration during the crushing process. The two sets of crushing components 3 arranged parallel to each other in the middle of the support frame 2 allow for dual crushing of waste compared to a single crushing structure, greatly improving crushing efficiency and effect. The combined design of the grooves 4 and adjustment components 5 allows for precise adjustment of the distance between the two sets of crushing components 3, meeting the crushing needs of different types and hardness of waste, and improving the applicability of the equipment.

[0026] The adjusting component 5 includes a U-shaped frame 51 installed inside the slide chute 4 and an electric push rod 52 that pushes the U-shaped frame 51 to slide. Limiting blocks 53 for limiting the movement of the crushing components 3 are installed at both ends of the U-shaped frame 51. One set of crushing components 3 is located in the middle of the two sets of limiting blocks 53. The adjusting component 5 drives the corresponding crushing component 3 to move along the slide chute 4 via the U-shaped frame 51. The other set of crushing components 3 is installed in the middle of the support frame 2. The electric push rod 52 can precisely control the sliding distance of the U-shaped frame 51 within the slide chute 4, thereby precisely adjusting the distance between the two sets of crushing components 3. The limiting blocks 53 installed at both ends of the U-shaped frame 51 limit the movement of the crushing components 3, ensuring that the crushing components 3 remain stable during movement and do not shift or shake. They also provide additional support to the crushing components 3 during crushing operations, enhancing their structural stability. Simultaneously, the design of the U-shaped frame 51 and the slide chute 4 ensures that the adjusting component 5 is subjected to uniform force during operation, reducing wear and extending the equipment's service life.

[0027] Preferably, the electric actuator 52 is mounted on the side of the support frame 2 via a support block. The output end of the electric actuator 52 is connected to the U-shaped frame 51 by bolts. This bolted connection method is simple and easy to operate. When the electric actuator 52 malfunctions or requires maintenance, the operator can quickly unscrew the bolts and remove it from the U-shaped frame 51 for easy inspection, replacement of parts, and other maintenance work, effectively reducing equipment downtime and lowering maintenance costs.

[0028] The 52 electric push rod uses the LINAKLA36 model, which features 600N thrust, 100-600mm adjustable stroke, and a repeatability accuracy of ±0.05mm. It allows for precise adjustment of the crushing component spacing to adapt to the crushing needs of different types of waste. Its IP66 protection rating effectively withstands the humid and dusty environment inside the waste bin, and its quiet design (<50dB) makes it suitable for public places. Furthermore, its 1 million cycle life far exceeds that of ordinary domestic models, ensuring long-term stable operation.

[0029] Furthermore, the crushing assembly 3 includes a servo motor 31 located in the middle of the support frame 2 for driving the rotating shaft 32 to rotate. A crushing roller 33 for crushing waste is installed in the middle of the rotating shaft 32. The servo motor 31 has high-precision speed and position control capabilities, and can accurately adjust the rotation speed and torque of the rotating shaft 32 according to the different characteristics of the waste and the crushing requirements. It can provide suitable crushing power for both high-hardness plastic bottles and soft textile waste, ensuring the stability and efficiency of the crushing effect. The crushing roller 33 installed in the middle of the rotating shaft 32 directly participates in the waste crushing process. The crushing roller 33 can squeeze, shear, and tear the input waste through its own rotational motion.

[0030] The servo motor 31 uses the SGM7G-1EA6C model, which has a rated power of 1kW, supports a high speed of 3000 rpm and a 300% instantaneous overload capacity, and can quickly respond to sudden load changes during the waste crushing process, effectively preventing material jamming. It is equipped with a 20-bit high-resolution encoder to ensure precise speed control of the crushing rollers, and combined with Yaskawa's unique Σ-7 series drive algorithm, achieves smooth start-stop and high energy efficiency.

[0031] Furthermore, several sets of crushing wheels 34 are installed on the surface of the crushing roller 33. The crushing wheels 34 on the surfaces of the two sets of crushing rollers 33 are staggered. The multiple sets of crushing wheels 34 increase the contact area between the crushing roller 33 and the waste. When the waste enters between the two sets of crushing rollers 33, the staggered crushing wheels 34 can squeeze, tear, and shear the waste from multiple angles and directions. Compared with the smooth surface of the crushing roller, the waste can be crushed into smaller and more uniform pieces, effectively improving crushing efficiency and quality. The staggered arrangement of the crushing wheels 34 makes the force on the waste dispersed and irregular during the crushing process, reducing the situation of waste entanglement and jamming on the surface of the crushing roller 33, ensuring the continuity of crushing operation, and reducing the risk of equipment failure.

[0032] The crushing wheel 34 uses SKD11 mold steel as its base material, combined with a tungsten carbide coating of HV1000 or higher. This combination boasts an ultra-high hardness of 62HRC, and its wear resistance is three times that of ordinary 65Mn steel, significantly extending the service life of the crushing wheel. The special coating effectively reduces the adhesion rate of plastic and other waste by more than 50%, ensuring a smooth and unblocked crushing process.

[0033] It is worth noting that the support frame 2 is equipped with a recycling bin 6 for collecting crushed waste. The inlet of the recycling bin 6 is positioned corresponding to the crushing component 3, and the inlet of the recycling bin 6 faces the crushing component 3 directly. The crushed waste can fall directly into the recycling bin 6 under the action of gravity, without the need for additional conveying devices. This greatly shortens the path of waste from crushing to collection, ensuring a highly efficient and smooth crushing to recycling process and improving the overall waste treatment efficiency. The independently designed recycling bin 6 is easy to remove and clean. When the recycling bin 6 is full, the staff can directly pull it out of the support frame 2 and quickly replace it with a new recycling bin 6 to continue working.

[0034] Specifically, a mounting base 7 is installed on the lower surface inside the trash can 1 to drive the recycling bin 6 to slide. The recycling bin 6 is installed inside the mounting base 7 and slides inside the trash can 1 via the mounting base 7. When the recycling bin 6 is full of trash, workers do not need to laboriously move or disassemble complex parts; they can simply pull the recycling bin 6 gently to remove it smoothly along the mounting base 7, which is convenient and quick. When replacing the empty recycling bin 6, it can also be easily pushed in, greatly shortening the trash collection time and improving overall work efficiency.

[0035] More specifically, the interior of the trash can 1 has a sliding groove 8, and the mounting base 7 has movable blocks 9 on both sides that match the sliding groove 8. The cooperation between the movable blocks 9 and the sliding groove 8 provides precise guidance for the sliding process of the mounting base 7 driving the recycling bin 6. This ensures that when the recycling bin 6 is pushed in or taken out, it can only move along the trajectory defined by the sliding groove 8, avoiding deviation, jamming, or other situations, ensuring a smooth and stable sliding process, and effectively improving the reliability of the equipment.

[0036] 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.
