Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust covers for garbage compressors, specifically a split-type dust cover for garbage compressors. Background Technology
[0002] The garbage compactor is located at the garbage transfer station and is used to receive garbage trucks dumping garbage, compressing and filling it into a transfer container for processing. During the garbage truck dumping process, garbage and dust can easily spread to the outside of the garbage compactor, so a dustproof and material-blocking device is needed to prevent this.
[0003] Existing garbage compactors generally only have baffles around the outer perimeter of their feed hoppers. However, when garbage falls, it generates an upward backflow, which makes it difficult for the baffles to effectively block the garbage when the garbage truck dumps the garbage. A large amount of polluted gas or lightweight garbage (such as leaves, dust, plastic bags, etc.) will be dispersed into the garbage transfer station by the backflow of the falling garbage, causing secondary pollution.
[0004] The research objective of this utility model is to design a split-type dust cover for a garbage compressor to address the problems existing in the prior art. Utility Model Content
[0005] To address the problems existing in the prior art, this utility model provides a split-type garbage compressor dust cover, which can effectively solve the problems existing in the prior art.
[0006] The technical solution of this utility model is:
[0007] A dust cover for a split-type garbage compactor includes:
[0008] The cover is installed outside the discharge port of the corresponding garbage compressor. One side of the cover is provided with an inlet and outlet for the rear end of the corresponding garbage truck to enter and exit. Several exhaust holes are provided through the top. The side of the cover is rotatably provided with a movable door corresponding to the side end of the inlet and outlet. The movable door is driven by a swing drive device to swing laterally to adjust the width of the inlet and outlet.
[0009] Furthermore, the garbage compressor is vertically mounted in a corresponding pit. The top of the garbage compressor is provided with a hopper including the discharge port and connected to the inside of the garbage compressor, and a support platform located on one side of the discharge port. The cover is installed on the corresponding ground and the inlet and outlet face the support platform. The discharge port is separated from the inner wall of the cover and is vertically mounted inside the cover by the garbage compressor. The outer wall of the discharge port is provided with a plurality of first brushes that fill the gap between the discharge port and the inner wall of the cover.
[0010] Furthermore, the side of the feed hopper away from the support platform extends upward at an angle to form a baffle, and the lower end of the cover away from the inlet and outlet is recessed upward to form a notch whose upper height matches the lowest height of the baffle.
[0011] Furthermore, the height of the cover is always higher than the height of the feed hopper, and the opening on one side of the cover forms a clearance opening whose height is always higher than the height of the support platform. The inlet and outlet are connected and located below the clearance opening. There are two movable doors that are symmetrically rotatably embedded on both sides of the cover. There are two swing drive devices that are rotatably located on the outer walls of both sides of the cover and whose telescopic ends are movably connected to the outer walls of the two movable doors.
[0012] Furthermore, the inner wall of the movable door is provided with several spaced mounting seats, several ball bearings rotatably embedded in the mounting seats, and several vertically arranged second brushes. After the movable door is swung back to its original position, it is spaced apart from the rear end of the garbage truck. Several ball bearings roll against the rear end side wall of the garbage truck, and several second brushes fill the gap between the movable door and the rear end of the garbage truck.
[0013] Furthermore, the telescopic end of the swing drive device is connected to the movable door through a buffer assembly. The buffer assembly includes a spring, a hinge seat fixed to the outer wall of the movable door, and a hinge member that is laterally rotatably connected to the hinge seat. The hinge member has a sliding cavity. The telescopic end of the swing drive device is limited and slidably inserted into the sliding cavity. The two ends of the spring are respectively fixed to the sliding cavity and the telescopic end of the swing drive device.
[0014] Furthermore, the cover includes a frame and several baffles that can be detachably installed on the frame, and several legs extending downward from the bottom of the frame for fixing to the corresponding ground.
[0015] Therefore, the beneficial effects of this utility model are:
[0016] 1. By using a hood with an entrance / exit on one side, the hood effectively blocks the large amount of polluted gas and lightweight garbage that rises upwards due to the backflow of the falling garbage when the garbage truck enters the entrance / exit and dumps garbage into the discharge port. This prevents the garbage from drifting into the garbage transfer station and causing secondary pollution, improving the hood's material-blocking effect and practicality. Simultaneously, the several exhaust holes on the top of the hood allow the backflow of air to be smoothly discharged and depressurized, reducing the probability of increased air pressure inside the hood causing the backflow to rush outwards from the entrance / exit, thus improving the stability of the hood's material-blocking function. Based on this, the addition of a movable door increases the adjustable width of the entrance and exit. When facing a garbage truck whose rear door opens to the side and is flush against the side wall, the entrance and exit width can be increased by first swinging the movable door outward to allow the rear of the garbage truck to enter the cover and open the door. Then, the movable door can be reset by swinging inward to stop the garbage. This increases the opening and closing function of the movable door while ensuring the material-stopping function of the cover. This allows garbage trucks with rear doors that open and close in different ways to dump their rear end into the cover before opening the rear door, avoiding premature opening of the door and causing garbage to fall outside the cover, thus improving the adaptability of the cover.
[0017] 2. By setting a gap between the feed hopper and the inner wall of the cover, the cover is designed so that it does not affect the lifting and lowering of the garbage compressor. At the same time, several first brushes are set on the outer wall of the feed hopper to fill the gap. Through the shielding effect of the first brushes, dust and garbage inside the cover are prevented from entering the pit through the gap when the garbage compressor is lifted and lowered. Thus, the dust cover can not only stably prevent dust from being poured by the stationary garbage compressor, but also stably prevent dust from being poured by the lifting garbage compressor, which greatly improves the adaptability and practicality of the dust cover.
[0018] 3. The baffle can guide the falling waste, improving the falling effect. The notch can reduce the material consumption of the dust cover and lower the production cost.
[0019] 4. By setting up two movable doors, when the dust cover faces a garbage truck with the rear door opening to both sides and fitting against the side wall, the width of the entrance and exit can be increased by first swinging the two movable doors outward to allow the rear of the garbage truck to enter the cover and open the door, and then the material can be blocked by swinging the two movable doors inward. This further improves the functionality of the movable door opening and closing and provides the dust cover with adaptability to different types of garbage trucks.
[0020] 5. By adding a second brush and ball bearings, in addition to filling the gap between the movable door and the rear end of the garbage truck through the second brush to prevent the foul gas and light garbage blocked by the cover from escaping from the entrance and exit to the outside of the cover, the rolling of several ball bearings can also achieve stable contact between the movable door and the rear side wall of the garbage truck after the movable door is reset, and avoid direct contact between the movable door and the rear end of the garbage truck to avoid wear. This improves the stability of the movable door in blocking material and extends its service life.
[0021] 6. By adding a buffer component, when the moving door experiences lateral swaying due to force during the lifting and lowering of the garbage truck body and when the garbage truck drives out of the cover, the spring contraction provides elastic buffering between the moving door and the telescopic end of the swing drive device. This prevents the moving door from being deformed and damaged by the rigid limit of the telescopic end, and ensures that the ball bearings always roll against the rear end of the garbage truck, ensuring the material blocking effect of the second brush and improving the stability and service life of the moving door in blocking material.

[0028] Figure 7 This is a partial cross-sectional view of the swing drive device in Embodiment 2. Detailed Implementation
[0029] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:
[0030] Example 1
[0031] refer to Figure 1-4 A dust cover for a split-type garbage compactor, comprising:
[0032] The cover 1 is installed outside the discharge port 311 of the corresponding garbage compressor 3. One side of the cover 1 is provided with an inlet 11 for the rear end of the corresponding garbage truck to enter and exit, and several exhaust holes 12 are provided through the top. The side of the cover 1 is rotatably provided with a movable door 13 corresponding to the side end of the inlet 11. The movable door 13 is driven by a swing drive device 2 to swing laterally to adjust the width of the inlet 11. Specifically, the swing drive device 2 is a hydraulic cylinder.
[0033] The aforementioned structure, through the covering effect of the hood 1 with one side serving as the inlet / outlet 11, ensures that when the garbage truck enters the inlet / outlet 11 from the rear and dumps garbage towards the discharge port 311, the hood 1 can effectively block a large amount of polluted gas and lightweight garbage that is swept upwards by the backflow of the falling garbage, thus preventing them from drifting into the garbage transfer station and causing secondary pollution. This improves the material-blocking effect and practicality of the hood 1. Simultaneously, the arrangement of several exhaust holes 12 on the top of the hood 1 allows the backflow of airflow to be smoothly discharged and depressurized through these holes, reducing the probability of increased air pressure inside the hood 1 causing the backflow of airflow to rush outwards towards the inlet / outlet 11, thereby improving the material-blocking stability of the hood 1. Furthermore, through… The addition of the movable door 13 increases the width adjustment function of the entrance / exit 11. When facing a garbage truck whose rear door opens to the side and fits against the side wall, the width of the entrance / exit 11 can be increased by first swinging the movable door 13 outward to allow the rear of the garbage truck to enter the cover 1 and open the door. Then, the width of the entrance / exit 11 can be decreased by swinging the movable door 13 inward to fit the rear of the garbage truck. This increases the opening and closing function of the movable door 13 while ensuring the material blocking function of the cover 1. This allows garbage trucks with rear doors that open and close in different ways to dump their rear into the cover 1 before opening the rear door, avoiding premature opening of the door and causing garbage to fall outside the cover 1, thus improving the adaptability of the cover 1.
[0034] To further improve the adaptability of the dust cover, the garbage compressor 3 is installed vertically in the corresponding pit. The top of the garbage compressor 3 is provided with a hopper 31 including the discharge port 311 and connected to the inside of the garbage compressor 3, and a support platform 51 located on one side of the discharge port 31. The cover 1 is installed on the corresponding ground and the inlet / outlet 11 faces the support platform 51. The discharge port 31 is separated from the inner wall of the cover 1 and is installed vertically in the cover 1 by the garbage compressor 3. The outer wall of the discharge port 311 is provided with a number of first brushes that fill the gap between the discharge port 31 and the inner wall of the cover 1. Specifically, the first brush is a dustproof brush. A lifting mechanism 5 is provided in the pit. The garbage compressor 3 is located in the lifting mechanism 5. The support platform 51 is located on top of the lifting mechanism 5. A transfer box 6 for connecting the discharge port of the garbage compressor 3 is provided in the lifting mechanism 5. When dumping garbage, the lifting mechanism 5 drives the garbage compressor 3 to descend into the pit. The garbage truck travels on the support platform 51 and enters the cover 1 through the inlet 11 at the rear end to dump material into the feed hopper 31. After dumping and garbage compression are completed, the lifting mechanism 5 drives the garbage compressor 3 and the rotating box to rise above the ground. The hook-lift truck hooks out the transfer box 6 and transfers it, and then replenishes the empty rotating box into the lifting mechanism 5.
[0035] The above-mentioned structure, through the gap between the feed hopper 31 and the inner wall of the cover 1, ensures that the setting of the cover 1 does not affect the lifting and lowering of the garbage compressor 3. At the same time, several first brushes are set on the outer wall of the feed hopper 31 to fill the gap. Through the shielding effect of the several first brushes, dust and garbage inside the cover 1 are prevented from entering the pit through the gap when the garbage compressor 3 is lifted and lowered. Thus, the dust cover can not only stably prevent dust and block material from being poured by the stationary garbage compressor 3, but also stably prevent dust and block material from being poured by the lifting garbage compressor 3, which greatly improves the adaptability and practicality of the dust cover.
[0036] To guide the falling waste and save on dust cover costs, the side of the feed hopper 31 away from the support platform 51 extends upward at an angle to form a baffle 312. The lower end of the cover 1 away from the inlet / outlet 11 is recessed upward to form a notch 14 whose upper height matches the lowest height of the baffle 312. Thus, the baffle 312 guides the falling waste, improving the falling efficiency, and the notch 14 reduces the amount of material needed for dust cover production, lowering production costs.
[0037] To further improve the adaptability of the dust cover, the height of the cover body 1 is always higher than the height of the feed hopper 31. One side opening of the cover body 1 forms a clearance opening 15 whose height is always higher than the height of the support platform 51. The inlet / outlet 11 is connected to the lower side of the clearance opening 15. Two movable doors 13 are symmetrically and rotatably embedded on both sides of the cover body 1. Two swing drive devices 2 are provided and rotatably mounted on the outer walls of both sides of the cover body 1, with their telescopic ends 21 movably connected to the outer walls of the two movable doors 13. Thus, by setting two movable doors 13, when facing a garbage truck whose rear door opens to the sides and fits against the side wall, the width of the inlet / outlet 11 can be increased by first swinging the two movable doors 13 outwards to allow the rear of the garbage truck to enter the cover body 1 and open the door, and then the two movable doors 13 can be reset inwards to stop the material flow. This further improves the functionality of the movable doors 13 in opening and closing, providing the dust cover with adaptability to different types of garbage trucks.
[0038] To improve the ease of disassembly and assembly of the dust cover, the cover body 1 includes a frame 16 and several baffles 17 that can be detachably installed on the frame 16. The bottom of the frame 16 extends downward and is provided with several legs 18 for fixing to the corresponding ground. Specifically, the several baffles 17 and the frame 16 are screwed together, and the several legs 18 are screwed to the ground.
[0039] Example 2
[0040] Although the installation of several exhaust vents 12 reduces the probability of increased air pressure inside the hood 1 causing backflow to rush outwards through the inlet / outlet 11, there is still a probability that polluted gas and lightweight waste will escape from the inlet / outlet 11 when the garbage truck dumps garbage and moves its rear end outside the hood 1. Therefore, to ensure the stability of the dust cover, refer to... Figure 5-7 The difference between this embodiment and Embodiment 1 is that:
[0041] The inner wall of the movable door 13 is provided with a plurality of spaced mounting seats 131, a plurality of rotatable ball bearings 132 embedded in the mounting seats 131, and a plurality of vertically arranged second brushes. After the movable door 13 is swung back to its original position, there is a gap between it and the rear end of the garbage truck. The plurality of ball bearings 132 roll against the rear end side wall of the garbage truck, and the plurality of second brushes fill the gap between the movable door 13 and the rear end of the garbage truck. Specifically, the second brushes are dustproof brushes, and the plurality of mounting seats 131 are arrayed on the inner wall of the movable door 13. Thus, by adding the second brush and the ball bearings 132, in addition to filling the gap between the movable door 13 and the rear end of the garbage truck by the second brush to prevent the foul gas and light garbage blocked by the cover 1 from escaping from the inlet 11 to the outside of the cover 1, the rolling abutment of several ball bearings 132 can also achieve stable contact between the movable door 13 and the rear side wall of the garbage truck after it is reset, and avoid the movable door 13 directly contacting the rear end of the garbage truck to avoid wear, thereby improving the material blocking stability of the movable door 13 and extending its service life.
[0042] Since the movable door 13 is in contact with the rear end of the garbage truck through several ball bearings 132, the movable door 13 will be subjected to a certain lateral sway during the lifting and lowering of the garbage truck body and the garbage truck driving out of the cover 1. The telescopic end 21 of the swing drive device 2 is rigidly abutted against the outside of the movable door 13, which can easily cause the movable door 13 to deform and be damaged. Therefore, the telescopic end 21 of the swing drive device 2 is connected to the movable door 13 through a buffer assembly 4. The buffer assembly 4 includes a spring 41, a hinge seat 42 fixed to the outer wall of the movable door 13, and a hinge member 43 that is laterally rotatably connected to the hinge seat 42. The hinge member 43 is provided with a sliding cavity 431. The end of the telescopic end 21 of the swing drive device 2 is limited and slidably inserted into the sliding cavity 431. The two ends of the spring 41 are respectively fixed to the sliding cavity 431 and the end of the telescopic end 21 of the swing drive device 2. Thus, by adding the buffer component 4, when the movable door 13 experiences a certain lateral sway during the lifting and lowering of the garbage truck body and the garbage truck driving out of the cover 1, the spring 41 can provide elastic buffering between the movable door 13 and the telescopic end 21 of the swing drive device 2. This prevents the movable door 13 from being deformed and damaged by the rigid limit of the telescopic end 21, and ensures that the ball bearing 132 always rolls against the rear end of the garbage truck, ensuring the material blocking effect of the second brush and improving the stability and service life of the movable door 13 in blocking material.
[0043] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.
[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
