[0030] With reference to Figure 2 The lower side wall of mounting frame 2 is fixedly provided with a guide chute 21, the guide chute 21 is a hollow prism structure with a large upper part and a small lower part and is through-connected, a screening disc 3 is rotatably arranged at a position near the top end of the guide chute 21 by a rotating rod 31, the rotating rod 31 is arranged at a position near the side opening of the shell 1 of the screening disc 3, the screening disc 3 is a square disc structure with an opening facing upward, when the screening disc 3 is in a horizontal state, the screening disc 3 is located below the bottom opening of the shell 1, when garbage enters the shell 1 from the side opening of the shell 1, the screening disc 3 receives the garbage, and a plurality of screen holes allowing fibrous impurities to pass through are formed in the screening disc 3.

[0031] When the transport vehicle puts the kitchen waste into the inside of the shell 1, the kitchen waste falls on the screening disc 3 under the action of gravity, and large sundries such as glass bottles in the kitchen waste cannot pass through the screen holes and accumulate in the inside of the screening disc 3, and the fiber impurities such as skin leaves in the kitchen waste fall below the screening disc 3 through the screen holes, so that the kitchen waste is classified and treated according to the size, facilitating subsequent pretreatment of different types of garbage.

[0033] The structure of the driving assembly will be detailed below, referring to Figure 2 and Figure 6The driving assembly comprises a conveying motor 56 fixedly installed on the mounting frame 2 through a support, a driving wheel is coaxially fixed on an output shaft of the conveying motor 56 through dovetail joints, one end of the main shaft 52 is coaxially fixed with a driven wheel through dovetail joints, and the driven wheel and the driving wheel are transmissionally connected with the same transmission belt. When the output shaft of the conveying motor 56 drives the driving wheel to rotate, the driving wheel drives the driven wheel and the main shaft 52 to rotate through the transmission belt, so that the main shaft 52 can drive the auger blade 53 to rotate to convey the fiber impurities.

[0034] When the large impurities in the inside of the screening disc 3 need to be removed by the staff periodically to avoid that the large impurities shield the screen holes, so that the fiber impurities are accumulated above the large impurities and cannot pass through the screen holes, the staff in the prior art needs to use a rake, a broom or the like to sweep the large impurities out of the screening disc 3, which consumes a lot of physical strength of the staff. To solve this problem, an inclined plate is arranged on one side of the screening disc 3 close to the side opening of the shell 1, and a turnover mechanism 4 for driving the screening disc 3 to rotate around the axis of the rotating rod 31 is arranged on the material guide hopper 21. Referring to Figure 5 The turnover mechanism 4 drives the screening disc 3 to rotate, so that the screening disc 3 rotates around the position connected with the rotating rod 31. When the end of the screening disc 3 away from the inclined plate is turned upward, the screening disc 3 is turned to the upper side of the mounting frame 2, and one end of the inclined plate is turned to the outside of the mounting frame 2. At this time, the side of the screening disc 3 provided with the screen holes is turned to an inclined state, and the large impurities accumulated in the inside of the screening disc 3 slide to the outside of the shell 1 under the action of gravity. Before the garbage left after screening by the screening disc 3 is collected, the staff places a large impurity collecting box on the side of the shell 1 close to the side opening, and the height of the collecting box is less than that of the screening disc 3. After the large impurities slide from the inside of the screening disc 3 to the outside of the shell 1, the large impurities fall into the inside of the collecting box under the action of gravity to be collected, so that the large impurities are quickly cleaned.

[0035] When the turnover mechanism 4 drives the screening disc 3 to turn over, the screening disc 3 can be reciprocatingly rotated in a small range, so that the kitchen waste in the inside of the screening disc 3 is vibrated synchronously. The kitchen waste changes positions continuously during the vibration process, so that the fiber impurities accumulated on the large impurities can be transferred to the lower layer of the large impurities, so that the fiber impurities fall out through the screen holes, and the screening quality of the screening disc 3 for the kitchen waste is improved.

[0036] The structure of the turnover mechanism 4 is described below. Referring to Figure 3 and Figure 4, the turnover mechanism 4 comprises a support rod 41 rotatably arranged at the side of the material guide hopper 21 close to the side opening of the shell 1, the other end of the support rod 41 is fixedly provided with an arc-shaped rack 42, the end of the arc-shaped rack 42 close to the material guide hopper 21 is coaxially fixedly provided with an arc-shaped rod 45, the axis of the arc-shaped rod 45 and the arc-shaped rack 42 and the axis of the rotation of the support rod 41 are on the same straight line, the other end of the arc-shaped rod 45 slides through the side of the material guide hopper 21 and is in contact with the lower side wall of the screening disc 3, and the position of the arc-shaped rod 45 in contact with the screening disc 3 is located on the side of the rotating rod 31 away from the side opening of the shell 1, at this time the arc-shaped rack 42 and the arc-shaped rod 45 are in the initial position, the turnover mechanism 4 further comprises a limiting frame 47 fixedly arranged at the lower side wall of the screening disc 3, the limiting frame 47 is a U-shaped frame with both ends fixedly arranged on the screening disc 3, the limiting frame 47 is arranged at the position of the screening disc 3 close to the side opening of the shell 1, a through slot 46 is formed on the arc-shaped rod 45 close to the screening disc 3, the limiting frame 47 is slidingly arranged in the through slot 46, the turnover mechanism 4 further comprises a turnover motor 43 fixedly installed on the lower side of the material guide hopper 21 through a support, a gear 44 is coaxially fixedly installed on the output shaft of the turnover motor 43 through a dovetail joint, the gear 44 is engaged with the arc-shaped rack 42.

[0037] When it is necessary to dump the large pieces of sundries in the screening disc 3, the operator controls the output shaft of the turnover motor 43 to drive the gear 44 to rotate, the arc-shaped rack 42 is driven to rotate by the engagement transmission of the gear 44 and the arc-shaped rack 42, the arc-shaped rod 45 and the support rod 41 are driven to rotate around the connection between the support rod 41 and the material guide hopper 21, the arc-shaped rod 45 rotates upward to lift the screening disc 3, in this process the arc-shaped rod 45 moves between the screening disc 3 and the limiting frame 47, so that the screening disc 3 rotates upward around the axis of the rotating rod 31 to dump the large pieces of sundries in the screening disc 3, the turnover motor 43 is a servo motor with adjustable rotating direction, an electronic lock is installed in the turnover motor 43, when the turnover motor 43 is in the unused state, the electronic lock prevents the output shaft of the turnover motor 43 from rotating, so that the arc-shaped rack 42 can be kept stable in the initial position, when the output shaft of the turnover motor 43 drives the gear 44 to rotate reversely, the arc-shaped rack 42, the arc-shaped rod 45 and the support rod 41 all rotate in the opposite direction, the arc-shaped rod 45 pulls the limiting frame 47 and the screening disc 3 to rotate downward around the axis of the rotating rod 31 through the through slot 46, so that the screening disc 3 is reset, preventing the screening disc 3 from being unable to reset under the action of gravity due to excessive friction between the screening disc 3 and the inner wall of the shell 1, at the same time, the operator can control the rotating direction and rotating angle of the output shaft of the turnover motor 43, so that the arc-shaped rod 45 drives the screening disc 3 to reciprocate with small amplitude, so that the screening disc 3 can screen the kitchen waste in it.

[0038] In order to improve the appearance of the device in the idle state, an automatic cover 6 is arranged in the shell 1, referring to Figure 3The automatic cover plate 6 comprises a fixed cover plate 61 obliquely fixedly arranged in the inside of the shell 1, an upper side wall of the fixed cover plate 61 is slidably provided with a movable cover plate 62, and a motor-driven telescopic rod 63 is fixedly arranged between a side of the movable cover plate 62 away from the side opening of the shell 1 and the inner wall of the shell 1. When the device is in a working state of processing kitchen waste, the piston rod of the motor-driven telescopic rod 63 is retracted to the shortest position, the piston rod of the motor-driven telescopic rod 63 pulls most of the movable cover plate 62 to the upper side of the fixed cover plate 61, so that a larger space is formed between the side of the movable cover plate 62 away from the motor-driven telescopic rod 63 and the side of the screening disc 3 close to the side opening of the shell 1, and the transport vehicle can transport the kitchen waste to the inside of the screening disc 3 through the space. When the device is in an idle state, the worker controls the piston rod of the motor-driven telescopic rod 63 to extend to the longest position, so that the motor-driven telescopic rod 63 drives the movable cover plate 62 to extend into the side opening of the shell 1, at this time, the movable cover plate 62 and the fixed cover plate 61 cooperate to completely cover the screening disc 3, so as to avoid the kitchen waste stains on the screening disc 3 from being exposed to the view of the personnel, thereby improving the appearance of the device in the idle state, and referring to Figure 5 When the screening disc 3 dumps large pieces of sundries, the automatic cover plate 6 does not interfere with the rotation of the screening disc 3 and the dumping of the large pieces of sundries, so as to ensure that the function of cleaning the large pieces of sundries of the device is not affected.

The worker assembles the rapid deployment structure first, and then installs the anti-blocking draining assembly on the corresponding position of the rapid deployment structure, so as to complete the deployment of the device. The process of installing the anti-blocking draining mechanism does not need to use concrete, thereby improving the deployment efficiency of the device.

[0040] When the device is used, an operator places the sewage tank below the draining hole of the draining cylinder 51, places the waste tank directly below the discharge port 55, and then puts the kitchen waste into the inside of the screening disc 3 through the side opening of the shell 1, in the process, the operator can control the rotating direction and rotating angle of the output shaft of the overturning motor 43, so that the overturning mechanism 4 drives the screening disc 3 to reciprocatingly rotate at a small amplitude, so that the screen holes on the screening disc 3 quickly separate the large pieces of sundries and fiber impurities in the kitchen waste, the fiber impurities separated by the screening disc 3 fall into the inside of the draining cylinder 51 through the guide hopper 21, and the fiber impurities are subjected to dewatering treatment through the draining mechanism 5, the water separated from the fiber impurities is collected in the inside of the sewage tank, and the dewatered fiber impurities are collected in the inside of the waste tank, when the kitchen waste is put in, the operator places the large sundries collecting tank on the side of the shell 1 close to the side opening, and then overturns the screening disc 3 by the overturning mechanism 4 to a larger amplitude to pour the large sundries in the inside of the screening disc 3 into the inside of the collecting tank, so that the front-end pretreatment of the kitchen waste is completed.
