[0002] At present, the mainstream solid waste classification and disposal include large fixed sorting centers and simple on-site crushing and screening. The main problems of large fixed sorting centers are as follows: 1. Huge cost investment; 2. Front-end vehicles are required to collect and transport to the sorting center, and the front-end vehicles do not have the garbage compression function, and can accommodate less garbage, so the efficiency of transportation and processing is low; the main problems of simple crushing and screening are as follows: 1. There are few types of classified materials and the classification is not thorough; 2. Dust, wastewater, and exhaust gas pollute the environment; 3. Bulk storage, occupying a large space; 4.

[0026] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] Combined with Figure 1-7 A solid waste disposal device is used to classify garbage, and then classify and process different types of garbage and store them. It specifically includes a carrier 1, a feeding structure 2, a coarse crushing structure 3, a material separation structure 4, and a compression structure 5.

[0029] The carrier 1 is a hollow box structure, which is used to cover the outside of various garbage processing and transmission components to prevent garbage from splashing and odor from overflowing.

[0030] The feeding structure 2 is arranged on the outer side of the carrier 1, and the feeding structure 2 includes a feeding track 21. A feeding port 22 is provided on the top side of the carrier 1. The feeding track 21 is laid from the side of the carrier 1 and extends to the opening of the feeding port 22. The feeding track 21 is composed of a vertical section located on the side of the carrier 1 and an arc section located on the top surface of the carrier 1. The vertical section and the arc section of the feeding track 21 have a rounded arc transition.

[0031] A locking member 23 is provided for sliding inside the loading track 21. The locking member 23 is a frame structure. Sliders that slide inside the loading track 21 are fixed at both ends of the locking member 23. A locking tooth 231 is provided on the locking member 23. The locking tooth 231 is used to cooperate with the armrest of the trash bin. The locking tooth 231 can be inserted into the armrest of the trash bin, thereby driving the trash bin to move synchronously when the locking member 23 moves.

[0032] A support member 24 is also slidably provided on the upper side of the locking member 23 in the loading track 21. The support member 24 is a frame structure. The locking member 23 is located in the support frame 24. The top of the support member 24 is a top plate 241. The top plate 241 is used to cooperate with the locking tooth 231 to fully engage the handrail of the trash can. The support member 24 is only slidably set on the upper side of the loading track 21. A sliding block that slides in the loading track 21 is a rectangular sliding block.

[0033] A hydraulic rod 25 is fixedly provided on the side of the carrier 1 of the support track 21, and a driving shaft 26 is rotatably provided on the output rod of the hydraulic rod 25. Gears are provided at both ends of the driving shaft 26. A chain 27 that cooperates with the gear is provided on the side of the carrier 1 in the support track 21. One end of the chain 27 is fixedly set on the side of the carrier 1, and the other end is fixedly connected to the lower side of the clamping member 23. The chain 27 is wound around the gear, and a spring 28 is connected between the lower side of the clamping member 23 and the lower side of the support member 24.

[0034] When the garbage in the trash can is put into the feeding port 22: the hydraulic rod 25 is opened to lift the output rod upward, and the output rod moves the chain upward by pushing the shaft and the gear, and the chain synchronously drives the engaging member 23 to move, and the engaging member 23 moves upward along the feeding track 21. When the engaging member 23 starts to move, the engaging teeth 231 of the engaging member 23 bite the handrail of the trash can. As the engaging member 23 moves, the engaging teeth 231 of the engaging member 23 contact the top plate 241 of the supporting member 24, and while locking the handrail of the trash can, the engaging teeth 231 of the engaging member 23 are engaged with the supporting member 24. The top plate 241 abuts and drives the support member 24 to move upward synchronously. The support member 24 moves upward synchronously. When the support member 24 moves from the vertical section to the end of the arc section, the upper part of the support member 24 slides to the end of the arc section of the feeding track 21. At this time, since the slider of the support member 24 is a rectangular slider, the lower part of the support member 24 will tilt upward, and the support member 24 forms an inclined surface with the feeding port 22 located on the lower side. At this time, the engaging member 23 abuts against the upper part of the support member 24. When there is no resistance from the engaging member 23, the support member 24 will slide downward due to gravity.

[0035] When the support member 24 is tilted upward, it will abut against the body of the trash can and drive the body to tilt upward. At this time, the opening of the trash can is toward the feeding port 22 and tilted toward the feeding port 22, and the feeding port 22 is on the lower side of the trash can. At this time, the garbage in the trash can enters the feeding port 22.

[0036] When the trash can is put back, the output rod of the hydraulic rod 25 retracts, and the spring between the engaging member 23 and the support member 24 pulls the lower part of the support member 24 to rotate downward. As the output rod in the hydraulic rod 25 continues to retract, the support member 24 and the engaging member 23 move toward the lower side of the feeding track 21.

[0037] Located below the feed port 22 in the carrier 1 is a coarse crushing structure 3, which includes a coarse crusher 31 fixedly disposed in the carrier 1, a hopper 32 is provided on the top of the coarse crusher 31, the hopper 32 is located below the feed port 22 and fixedly connected to the feed port 22, and a hopper top cover 321 is provided on the hopper 32 which can be flipped over to cover the hopper 32.

[0038] The lower side of the coarse crusher 31 is a sewage collection box 61, which collects the sewage thrown into the coarse crusher 31 from the garbage bin for unified treatment. At the same time, a sewage treatment pipe can be set at the bottom of the carrier 1 to drain the sewage into the sewage treatment box 61.

[0039] The side of the coarse crushing structure 3 is a material dividing structure 4. A conveyor belt 41 is provided at the bottom of the coarse crusher 31. A conveyor belt cover 412 is provided on the conveyor belt 41. A plurality of air dispersion holes 413 are provided on the conveyor belt cover 412. One end of the conveyor belt 41 is connected to the bottom of the coarse crusher 31. A magnetic separator 42 and a star disk screen 43 are provided at the other end of the conveyor belt. A baffle 431 is provided on the star disk screen 43 on one side of the magnetic separator 42. The magnetic separator 42 is located on the upper side of the baffle 431. The baffle 431 prevents the iron garbage fragments magnetically attracted by the magnetic separator 42 from falling onto the star disk screen 43 when the magnetic separator rotates. The discharge port of the conveyor belt 41 is located at the top position of the magnetic separator 42. The rotation direction of the magnetic separator 42 is In the direction opposite to the direction in which the star disc screen 43 is located at the magnetic separator 42, that is, when the star disc screen 43 is located on the left side of the magnetic separator 42, the magnetic separator rotates clockwise, and after the coarse crusher 31 crushes the garbage, the garbage flows out through the conveyor belt 41 and falls to the top of the magnetic separator 42. The magnetic separator 42 is magnetic and can give a certain adsorption force to the iron-containing garbage. When the iron-containing garbage is located at the top of the magnetic separator 42, the magnetic separator 42 adsorbs the iron-containing garbage and drives the iron-containing garbage to rotate. The iron-containing garbage is then driven by the magnetic separator 42 to the top of the right side of the magnetic separator 42 and falls. On the right side of the magnetic separator is the iron-containing garbage collection box 44, and the iron-containing garbage 42 flows into the iron-containing garbage collection box 44 for storage.

[0040] The iron-free garbage enters the star disc screen 43, and the star disc screen 43 separates the iron-free garbage into upper garbage and lower garbage. The lower garbage falls from the star disc screen 43 and enters the compression structure 5, and the upper garbage is directly transported by the star disc screen 43 to the upper garbage storage box 45.

[0041] The compression structure 5 includes a variable compressor 51, on which a collecting hopper 52 is provided. The variable compressor 51 includes a compression box 511, on one side of the upper wall of the compression box 511, a feed port 512 is provided, one end of the collecting hopper 52 for collecting garbage is combined with the bottom of the star disk screen 43, the bottom surface of the star disk screen 43 is an open structure, and garbage falling at any position in the star disk screen 43 can enter the collecting hopper 52, and the collecting hopper 52 enters and converges the lower layer of garbage into the compression box 511, and a discharge port 526 is provided on the side of the lower wall of the compression box 511 away from the feed port 512.

[0042] A fixed screw and a movable screw are provided in the compression box 511. A fixed screw shaft 513 is rotatably provided on one side of the compression box 511. The fixed screw shaft 513 is provided with a right-handed variable pitch screw 514 in the compression box 511. A mounting plate 515 is provided on one side of the compression box 511. A fixed motor 516 is fixed on the mounting plate 515. The fixed motor 516 is connected to the fixed screw shaft 513, and the fixed motor 516 drives the right-handed variable pitch screw 514 to rotate.

[0043] An opening 517 is provided on the other side wall of the fixed spiral shaft 513 of the compression box 511, and a shaft mounting block 518 is slidably provided in the opening 517. A base member 519 is provided on one side of the compression box 511 located at the opening 517, and a push-pull hydraulic rod 520 is connected between the base member 519 and the shaft mounting block 518. The push-pull hydraulic rod 520 can drive the shaft mounting block 518 to move in the opening.

[0044] A movable spiral shaft 521 is installed in the shaft mounting block 18. The movable spiral shaft 521 is provided with a left-handed variable pitch screw 525 in the compression box 511. The mounting plate 515 is provided with a motor slide groove 522 on one side of the movable spiral shaft 521. A motor slider 523 is slidingly provided in the motor slide groove 522. A movable motor 524 is provided on the motor slider 523. The movable motor 524 is connected to the movable spiral shaft 521. When the hydraulic rod 520 is pushed and pulled to move the shaft mounting block 518, the movable motor 524 synchronously follows the movable spiral shaft 521 to move, thereby ensuring that the movable motor 524 can continuously provide power for the left-handed variable pitch screw 525.

[0045] The right-handed variable pitch screw 514 and the left-handed variable pitch screw 525 are both variable pitch screws. The pitches of the right-handed variable pitch screw 514 and the left-handed variable pitch screw 525 gradually shorten as they approach the discharge port 526. The right-handed variable pitch screw 514 preferably rotates clockwise, and the left-handed variable pitch screw 525 preferably rotates counterclockwise.

[0046] The rotation directions of the right-handed variable pitch spiral 514 and the left-handed variable pitch spiral 525 are opposite, and when the right-handed variable pitch spiral 514 and the left-handed variable pitch spiral 525 rotate, the garbage can be gathered between the right-handed variable pitch spiral 514 and the left-handed variable pitch spiral 525. The spiral setting mode of the right-handed variable pitch spiral 514 and the left-handed variable pitch spiral 525 is designed following the rotation direction of the right-handed variable pitch spiral 514 and the left-handed variable pitch spiral 525, so that when the right-handed variable pitch spiral 514 and the left-handed variable pitch spiral 525 rotate, they drive the garbage to move to the side of the discharge port 526.

[0047] When the garbage flows into the collecting bucket 52 normally, the movable spiral shaft 521 is located in the center position of the opening 517, and the garbage is compressed normally at this time. When the amount of garbage flowing in is too large, the push-pull hydraulic rod 520 pulls the shaft mounting block 518 to move away from the right-handed variable pitch screw 514, thereby making the left-handed variable pitch screw 525 move away from the right-handed variable pitch screw 514, and the distance between the right-handed variable pitch screw 514 and the left-handed variable pitch screw 525 is increased, thereby ensuring that the right-handed variable pitch screw 514 and the left-handed variable pitch screw 525 can rotate smoothly, thereby realizing the compression function of the garbage and preventing the right-handed variable pitch screw 514 and the left-handed variable pitch screw 525 from getting stuck. When the amount of garbage flowing in is too small, the push-pull hydraulic rod 520 pushes the rotating shaft mounting block 518 to move towards the direction close to the right-handed variable pitch screw 514, so that the left-handed variable pitch screw 525 is close to the right-handed variable pitch screw 514, and the blades between the right-handed variable pitch screw 514 and the left-handed variable pitch screw 525 overlap. In this way, the garbage is compressed by the smaller pitch between the blades of the overlapping part of the left-handed variable pitch screw 525 and the right-handed variable pitch screw 514, so as to ensure the normal compression effect of the garbage when the amount of garbage is too small.

[0048] The left-handed variable pitch spiral 525 and the right-handed variable pitch spiral 514 are also provided with protrusions 527 and water-permeable holes 528, which are evenly distributed on the blades of the left-handed variable pitch spiral 525 and the right-handed variable pitch spiral 514. The protrusions 527 are randomly arranged on the spiral blades, and when the spacing between the left-handed variable pitch spiral 525 and the right-handed variable pitch spiral 514 is the smallest and the overlapping area of ​​the blades is the largest, the protrusions 527 on the left-handed variable pitch spiral 525 and the right-handed variable pitch spiral 514 will not interfere with each other. The protrusions 527 can assist the compression function of the left-handed variable pitch spiral 525 and the right-handed variable pitch spiral 514 and prevent the garbage from slipping, thereby ensuring that the left-handed variable pitch spiral 525 and the right-handed variable pitch spiral 514 push the compressed garbage to the discharge port 526; the water permeable holes 528 can provide more discharge locations for the liquid in the garbage when the left-handed variable pitch spiral 525 and the right-handed variable pitch spiral 514 compress the garbage, thereby facilitating the outflow of various liquids retained in the garbage.

[0049] The discharge port 526 of the compression box 511 is connected to the lower garbage compression storage box 53 at the rear of the carrier 1 .

[0050] The top of the carrier 1 is a winnowing machine 63, and the side of the carrier 1 is provided with a fan 62 connected to the winnowing machine 63. The fan 62 is connected to a light material storage box 64 set at the end of the carrier 1. The fan 62 is turned on to generate suction, and the suction of the fan 62 sucks the light material waste on the star disk screen 43 into the light material storage box 64 through the winnowing machine 63 for storage.

[0051] A dust / waste treatment unit 65 is provided at the top of the rear end of the carrier 1. The dust / waste treatment unit 65 can treat the odorous gas and dust from the light material storage box 64, the lower garbage compression storage box 53 and the upper garbage storage box 45 to prevent the garbage from polluting the surrounding environment.

[0052] The carrier 1 can be directly mounted on the frame of a van, thereby forming a garbage collection and processing vehicle that is easy to move and has a wide range of uses.

[0053] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
