[0027] See also Figures 1 to 6 The kitchen waste crushing device 16 provided in the present application is configured with a cutting plate 162 and a push plate 163 at both ends of a discharge chamber 161, and the push plate 163 moves relative to the cutting plate 162, so that the kitchen waste in the compression chamber 1631 between the cutting plate 162 and the push plate 163 is compressed, cut into small pieces through the cutting hole 1621 of the cutting plate 162, and then discharged. The shredded small pieces of waste are more conducive to the decomposition and processing of the kitchen waste after it enters the decomposition site.

[0028] See also Figure 1 and Figure 2 , the present application provides a kitchen waste crushing device 16, comprising: a discharge chamber 161, a cutting plate 162 and a pushing plate 163. The discharge chamber 161 can be fixedly installed on the kitchen waste bin 122 by a bracket, or it can be fixed to other supporting members near the kitchen waste bin 122 by a bracket. In this embodiment, the placement chamber is connected to the frame above the kitchen waste bin 122 by bolts; the upper end of the discharge chamber 161 is provided with an inlet 1611 for allowing kitchen waste to be put in, and any side wall of the discharge chamber 161 is also provided with an outlet 1612 for discharging kitchen waste; the shape of the discharge chamber 161 can be a rectangular parallelepiped, a cylinder, or any other geometric shape that meets the requirements of garbage holding, and no specific limitation is made here; the cutting plate 162 is fixedly connected to the outlet 1612, and the outer dimensions of the cutting plate 162 match the cross-sectional shape of the outlet 1612. The fixed connection method can be any method that meets the requirements, such as clip connection, bolt connection, etc. The method of connection requirements; a plurality of cutting holes 1621 for cutting kitchen waste are evenly opened on the surface of the cutting plate 162, and the shape of the cutting hole 1621 can be any geometric shape that can meet the size requirements of the kitchen waste after cutting, such as square, rectangle, triangle, etc.; the discharge chamber 161 is connected to the garbage inlet of the kitchen waste bin 122 through the cutting hole 1621; the push plate 163 is slidably installed on the discharge chamber 161 and is installed opposite to the cutting plate 162. In the discharge chamber 161, a compression chamber 1631 with variable volume is formed between the plate and the cutting plate 162. The minimum volume of the compression chamber 1631 can be 0, and the maximum volume of the compression chamber 1631 is equal to the volume of the entire discharge chamber 161. When the push plate 163 moves close to the cutting plate 162 along the extension direction of the discharge chamber 161, the volume of the compression chamber 1631 becomes smaller, and when the push plate 163 moves away from the cutting plate 162, the volume of the compression chamber 1631 becomes larger.

[0029] The food waste is placed into the discharge chamber 161 through the feed port 1611. The push plate 163 then moves along the extension direction of the discharge chamber 161 toward the cutting plate 162. Simultaneously, the compression chamber 1631 shrinks, and the food waste in the compression chamber 1631 approaches the cutting plate 162 under the pressure of the push plate 163. The push plate 163 continues to compress the food waste, forcing it out of the cutting hole 1621. The cutting hole 1621 cuts the entire block of food waste into smaller pieces, which are then discharged into the food waste bin 122. This shredding device has a simple structure and is easy to operate. It achieves the shredding process of a whole block of food waste, facilitating its subsequent decomposition and processing.

[0030] See also Figure 1 and Figure 2 In an example of the kitchen waste crushing device 16 of the present application, the push plate 163 is movably arranged on the side wall of the discharge chamber 161 through a linear drive component 164. The linear drive component 164 can be any mechanism that can achieve linear movement, such as a cylinder, a hydraulic cylinder, a screw assembly, etc. In this embodiment, the linear drive component 164 is a cylinder, and the cylinder body of the cylinder is fixedly connected to the frame with the discharge chamber 161 by bolts. The piston end of the cylinder is threadedly fixedly connected to the push plate 163, and the extension direction of the piston is consistent with the discharge chamber 1 161, the length of the push plate 163 extends in the same direction, and the outer dimensions of the push plate 163 correspond to the outer dimensions of the cutting plate 162. When the piston extends, the piston drives the push plate 163 to move closer to the cutting plate 162, causing the compression chamber 1631 to become smaller. Under the action of the thrust, the food waste in the compression chamber 1631 is cut into small pieces and discharged from the cutting hole 1621. After cutting is completed, the piston retracts, driving the push plate 163 away from the cutting plate 162, causing the compression chamber 1631 to become larger, preparing for the next food waste storage and cutting. This arrangement can achieve automatic cutting of the food waste in the placement chamber, and the cutting force can be adjusted to better meet the requirements of food waste cutting.

[0031] See also Figure 1 and Figure 2 In one example of the kitchen waste shredder device 16 of the present application, the discharge chamber 161 is formed by two perpendicular side walls connected to form an L-shaped structure with an opening facing upward. The opening serves as a feed inlet 1611 for the waste. The length of the side walls corresponds to the length of the discharge chamber 161, and the width of the side walls corresponds to the height of the discharge chamber 161. The L-shaped structure of the discharge chamber 161 makes the cross-section of the discharge chamber 161 wide at the top and narrow at the bottom. When the kitchen waste enters the placement chamber, the two side walls of the L-shaped structure can effectively guide it. Under the premise of facilitating the placement of the waste, the waste can more smoothly enter the bottom of the placement chamber under the action of its own gravity, thereby effectively utilizing the volume of the discharge chamber 161.

[0032] See also Figure 1 and Figure 2In one example of the kitchen waste crushing device 16 of the present application, a guide member 1613 is provided on the side wall of the L-shaped structure. The guide member 1613 can be provided on any one side wall of the L-shaped structure, or on both side walls at the same time. In this embodiment, guide members 1613 are provided on both side walls of the L-shaped structure. The length direction of the guide member 1613 is consistent with the length direction of the side wall of the L-shaped structure. The cross-section of the guide member 1613 can be any geometric shape such as a triangle, a circle or a trapezoid. In this embodiment, the guide member 1613 has a triangular cross-section and the L-shaped Guide members 1613 are installed on both sides of the structure on the side away from each other. The length of guide members 1613 is equal to the length of the side walls of the L-shaped structure. The guide members 1613 and the side walls can be integrally formed or detachably connected. Considering the convenience of installation, in this embodiment, the two guide members 1613 are integrally formed at the edges of the two side walls of the L-shaped structure, and a guide groove is formed at each edge. The two adjacent side walls of the push plate 163 are slidably abutted against the two side walls of the L-shaped structure, and the two corresponding corners of the push plate 163 are slidably engaged in the guide groove. The provision of guide members 1613 guides the reciprocating sliding of the push plate 163. At the same time, the provision of guide members 1613 in both circumferential directions of the push plate 163 can also suppress the lateral bending deformation caused by the sliding of the push plate 163, thereby reducing the damage to the piston end of the cylinder caused by the lateral bending force.

[0033] See also Figure 3 and Figure 4 In an example of the kitchen waste crushing device 16 of the present application, because the two side walls of the L-shaped structure are arranged vertically, the corresponding cutting plate 162 is arranged to be a rectangular structure; rectangular cutting holes 1621 are opened on the cutting plate 162 with a rectangular structure, which is more convenient for uniform arrangement. Therefore, in this embodiment, the cutting holes 1621 on the cutting plate 162 are rectangular cutting holes 1621; at the same time, blades 1621 are processed on the side walls around the rectangular cutting hole 1621 on the side close to the push plate 163; the setting of the blade 1621 can improve the cutting efficiency of the kitchen waste in the cutting hole 1621.

[0034] See also Figure 2 and Figure 4 In one example of the kitchen waste shredder 16 of the present application, the rectangular cutting holes 1621 are thickened near the side walls of the cutting plate 162. Because the side walls of the cutting plate 162 are integrally connected to the two side walls of the L-shaped structure, a partial frame structure is formed between the cutting plate 162 and the L-shaped structure. The thickened rectangular cutting holes 1621 near the side walls of the cutting plate 162 can increase the support strength of the partial frame structure, thereby reducing the deformation of the cutting plate 162 during the cutting process, thereby correspondingly improving the cutting quality and service life of the cutting plate 162.

[0035] See also Figure 2 and Figure 4 In one example of the food waste shredding device 16 of the present application, a protrusion 1632 is provided on the side of the push plate 163 near the cutting plate 162. The protrusion 1632 can be inserted and exited along the cutting hole 1621. The protrusion 1632 can be square, round, or any other shape that can be inserted and exited through the cutting hole 1621. In this embodiment, the cutting hole 1621 is a rectangular cutting hole 1621, and the protrusion 1632 is a corresponding rectangular protrusion 1632. The number of protrusions 1632 corresponds to the number of rectangular cutting holes 1621. By providing the protrusions 1632, when the waste is being cut in the cutting plate 162, the push plate 163 can continue to operate until the protrusion 1632 penetrates the cutting hole 1621, allowing the food waste remaining in the cutting hole 1621 to be completely discharged and fall into the food waste bin 122. This reduces the probability of the cutting hole 1621 being blocked, thereby correspondingly improving the efficiency of food waste cutting.

[0036] See also Figure 4 In an example of the kitchen waste shredding device 16 of the present application, the shredding device also includes a cutting mechanism 165, and the cutting mechanism 165 includes a rotating drive member 1651 and a cutting knife 1652. The rotating drive member 1651 can be any rotating mechanism such as a motor, a motor + a reducer or a hydraulic motor. Considering the convenience of maintenance and the low procurement cost, preferably, in this embodiment, the rotating drive member 1651 uses a brushless motor, and the base of the brushless motor is connected to the frame of the fixed discharge chamber 161 by bolts, and the output end of the brushless motor is connected to the rotating shaft of the cutting knife 1652. The cutting knife 1652 is close to the side of the cutting plate 162 away from the push plate 163, and the rotating axis of the cutting knife 1652 is perpendicular to the cutting plate 162. When the kitchen waste is cut and discharged from the cutting hole 1621, the brushless motor is operated at this time. The rotation of the brushless motor drives the cutting knife 1652 to rotate close to the outside of the cutting plate 162, and the kitchen waste discharged from the cutting hole 1621 is rotated and cut, so that the kitchen waste is further crushed and cut, thereby further facilitating the decomposition and processing of the kitchen waste after entering the decomposition site.

[0037] See also Figure 4In one example of the kitchen waste shredder device 16 of the present application, the cutting blade 1652 includes a rotating shaft 16521 and three blades 16522. The three blades 16522 are arranged in a circumferential array at one end of the rotating shaft 16521. The blades 16522 can be single-sided blades 16211 or double-sided blades 16211. The other end of the rotating shaft 16521 is keyed to the output shaft of the brushless motor, and the rotation axis of the rotating shaft 16521 is perpendicular to the extension direction of the cutting hole 1621. With this arrangement, when the brushless motor rotates, it drives the rotating shaft 16521 to rotate, and in turn drives the three blades 16522 on the rotating shaft 16521 to rotate simultaneously, thereby achieving continuous cutting of the kitchen waste discharged from the cutting hole 1621, thereby improving the cutting and shredding efficiency of the kitchen waste.

[0038] See also Figure 5 and Figure 6The present application also provides an intelligent classification trash can 1, including a box body 11, multiple classification trash cans 12, a trash placement plate 13, a trash identification mechanism 14, a trash grabbing mechanism 15 and a control system, and also includes the kitchen waste crushing device 16 as described above. The box body 11 is a closed structure consisting of a frame and a panel covering the outer surface of the frame. The frame is connected by multiple aluminum profiles. The frame is light in weight and easy to move and transport. The panel can be made of metal or plastic. In this embodiment, in order to facilitate the observation of the operation of the internal structure of the box body 11, the panel is an acrylic panel. The garbage inlet 111 can be opened on the top side wall of the panel or on the surrounding side walls of the panel. In this embodiment, in order to reduce the impact speed at the moment of falling when the garbage is thrown, the garbage inlet 111 is set on one side wall of the panel. Multiple classification trash cans 12 are set in the inner cavity of the box body 11. At the bottom, there are four classified trash cans 12, which are marked as recyclable trash cans, kitchen waste bins 122, hazardous waste bins and other trash cans. The side walls around the enclosure are provided with mounting openings corresponding to each classified trash can 12, and each classified trash can 12 can be taken out of and put into the box body 11 through the mounting openings; the garbage placement plate 13 is located above the classified trash can 12 and below the garbage placement port 111; the garbage placement plate 13 is connected to the garbage placement port 111; in this application, the garbage placement plate 13 can be fixedly connected to the surrounding frame by bolts, or it can be rotatably connected to the frame by a rotating mechanism In the present embodiment, the garbage placement plate 13 is rotatably connected to the frame, and the rotating mechanism can be a rotary cylinder, a hydraulic motor or a reduction motor. In the present embodiment, the rotating mechanism is a double servo, and the double servo base is fixedly connected to the frame below the garbage placement plate 13 through a bracket. The output shafts at both ends of the servo are respectively connected to the two ends of the bottom surface of the garbage placement plate 13. The rotation of the double servo output shaft drives the garbage placement plate 13 to flip, and the garbage placed on the placement plate can slide from one end into the hazardous waste bin at the lower end of the garbage placement plate 13; the kitchen waste crushing device 16 is arranged above the kitchen waste bin 122, and the kitchen waste crushing device The discharge port 1612 of 16 is connected to the feed port 1611 of the kitchen waste bin 122; the garbage identification mechanism 14 is arranged in the box body 11 to classify and identify the garbage on the garbage placement plate 13; the garbage identification device in this application can be any device that can classify and identify garbage, such as image recognition technology or radiographic detection, and is not specifically limited here. For the specific structure of the garbage identification device, please refer to the existing technology and will not be repeated here; in this application, the garbage identification mechanism 14 can also include a display screen 141, which is arranged on the top outer wall of the box body 11 to display the type and quantity of identified garbage.The fixed end of the garbage grabbing mechanism 15 is mounted on the peripheral frame by bolts. The mobile end of the garbage grabbing mechanism 15 can move in two mutually perpendicular directions, left and right and front and back, in the horizontal plane, and can be telescopically moved in the vertical direction. After the garbage grabbing mechanism 15 grabs the garbage on the garbage placement plate 13, it can move the grabbed garbage to the corresponding classified garbage bin 12 for placement. For the specific connection structure of the garbage grabbing mechanism 15, please refer to the specific structure in the prior art and will not be repeated here. The control system is electrically connected to the garbage identification device and the garbage grabbing mechanism 15. The control system receives the garbage classification identification information output by the garbage identification mechanism 14 and controls the garbage grabbing mechanism 15 to move in different paths according to the garbage classification identification information to complete the automatic classification and placement of garbage. At the same time, the dual servo and the kitchen waste crushing device 16 are also electrically connected to the control system. The control system can control the rotation of the dual servo and also control the operation of the kitchen waste crushing device 16.

[0039] Before the intelligent classification trash bin 1 is put into use, it is necessary to input some common types of garbage into the control system in advance and assign corresponding garbage classification labels to them. When the garbage identification device identifies the type of garbage, the control system can output the garbage classification label corresponding to the garbage and determine which of the four types of classified garbage the garbage is. During the operation of the intelligent classification trash bin 1, when garbage is thrown into the garbage inlet 111, the garbage enters the garbage placement plate 13; then the garbage identification mechanism 14 classifies and identifies the garbage placed on the garbage placement plate 13, and feeds back the identification information to the control system. The control system controls the operation of the grabbing mechanism according to the identification information. The grabbing mechanism moves to the garbage placement plate 13, grabs the garbage, and moves according to the different paths corresponding to the garbage classification given by the control system until it reaches the corresponding classification trash bin 12, and then throws the garbage into the garbage inlet 111. The cycle is repeated to complete the automatic classification and automatic delivery of the garbage thrown into the garbage inlet 111. When the garbage identification mechanism 14 identifies the garbage on the garbage placement plate 13, the garbage is automatically delivered to the garbage bin 12. When it is kitchen waste, the garbage grabbing mechanism 15 grabs the kitchen waste to the kitchen waste crushing device 16, and the kitchen waste crushing device 16 cuts and crushes the whole piece of kitchen waste. The kitchen waste after cutting and crushing is then discharged into the kitchen waste bin 122, which is beneficial to the later decomposition and treatment of the kitchen waste; in addition, during the entire garbage classification and delivery process, the control system controls the garbage identification structure and the garbage grabbing mechanism 15 to complete the autonomous classification and autonomous delivery process of the garbage delivered into the box body 11, omitting the manual classification and identification and classification delivery process of the delivered garbage. Therefore, the accuracy of garbage classification and delivery will not be affected by people's misunderstanding of the garbage classification method, thereby significantly improving the accuracy of garbage classification and delivery. At the same time, because the garbage placement plate 13 is connected to the frame through a double servo rotation, when the garbage identification device identifies that the garbage on the garbage placement plate 13 is hazardous garbage, the control system controls the double servo to flip and rotate toward the side where the hazardous garbage is located, so that the hazardous garbage is directly dumped from the garbage placement plate 13 into the hazardous garbage bin, and there is no need to use the garbage grabbing mechanism 15 to grab and place the hazardous garbage. This setting can improve the efficiency of placing hazardous garbage, and thus improve the garbage processing efficiency of the entire intelligent classification garbage bin 1.

[0040] The kitchen waste shredder device 16 of the present application and the intelligent sorting waste bin 1 including the same compress the kitchen waste placed in the compression chamber 1631 through the movement between the push plate 163 and the cutting plate 162. The compressed kitchen waste is discharged along the cutting holes 1621 provided on the cutting plate 162 under the action of the thrust, thereby shredding the kitchen waste placed in the discharge chamber 161 into small pieces, which are then discharged into the kitchen waste bin 122. The kitchen waste entering the kitchen waste bin 122 is thus shredded into small pieces. Compared to the overall recycling of kitchen waste, shredded small pieces are more conducive to the decomposition and processing of the kitchen waste after entering the decomposition site. Therefore, the present application effectively overcomes some practical problems in the prior art and has high utilization value and practical significance. The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the art may modify or alter the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by persons having ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in this application should still be covered by the claims of this application.
