[0001] The present invention relates to the technical field of garbage disposal, and in particular to a kitchen waste crushing and disposal device. Background Art

[0002] Kitchen waste refers to garbage generated in residents' daily lives and in food processing, catering services, unit meal supply and other activities, including discarded vegetable leaves, leftovers, leftover rice, fruit peels, egg shells, tea dregs, bones, etc. Its main sources are home kitchens, restaurants, hotels, canteens, markets and other industries related to food processing.

[0003] In the related art, a Chinese patent with publication number CN116511214A discloses a harmless treatment device for kitchen waste, including a frame, a progressive full crusher, a dehydration device and a material carrying box, wherein the progressive full crusher, the dehydration device and the material carrying box are arranged on the frame in sequence from top to bottom. The present invention belongs to the technical field of kitchen waste treatment, and specifically provides a harmless treatment device for kitchen waste, which effectively solves the problem that garbage needs to be graded before crushing and the steps are complicated in the current market. During the rotating crushing process, the technical effect of continuously reducing the spacing between the crushing knife groups is achieved by means of an ingenious mechanical structure, so that the kitchen waste is crushed progressively from large to small in sequence, and the kitchen waste is fully crushed while reducing the loss of the crushing knife group.

[0004] However, since there are many types of kitchen waste and the volumes are different, there are many small wastes that do not need to be crushed before the kitchen waste is crushed. If all the kitchen waste is directly crushed as in the above patent, on the one hand, the working intensity of the crusher will be increased, and on the other hand, more waste will contact the crushing mechanism, making the crushing mechanism in a dirty state. Summary of the invention

The driving device drives the filter plate to shake through the movement of the crushing mechanism, so that the filter plate guides the unfiltered garbage on the top to the entrance of the second channel.

[0010] As a further improvement of the present technical solution, a second material receiving hopper is fixedly provided on the inner wall of the filter plate, and the second material receiving hopper is located above the movable knife. The outer ring diameter of the filter plate is smaller than the diameter of the inner ring of the shell, so that a filtration channel is formed between the outer ring of the filter plate and the inner ring of the shell, and the filtration channel and the second material receiving hopper together constitute a second channel.

[0011] As a further improvement of the technical solution, the driving device includes a cam sleeved on the outer ring of one of the main shafts, and a driven rod located directly above the cam, and the top end of the driven rod passes through the second receiving hopper and abuts against the bottom of the filter plate.

[0012] As a further improvement of the present technical solution, the first channel includes a first material receiving hopper located below the filter plate, the bottom end of the first material receiving hopper is connected to a discharge pipe, the bottom end of the discharge pipe passes through the second material receiving hopper, and one side of the bottom end of the first material receiving hopper is fixedly connected to the inner wall of the shell.

[0013] As a further improvement of the technical solution, a plurality of ejector pins are fixedly provided on the top of the first receiving hopper, and the plurality of ejector pins are located below the filter holes at the top of the filter plate.

[0014] As a further improvement of the technical solution, a pressure rod is provided in the second receiving hopper, and the pressure rod is located above the two moving knives. The pressure rod is connected to a connecting piece for driving the pressure rod to move downward to press down the kitchen waste above the moving knives.

[0015] As a further improvement of the present technical solution, the connecting member is a connecting rod, both ends of the pressure rod pass through both sides of the second receiving hopper, one end of the connecting rod is fixedly arranged on the side wall of the driven rod, and the other end is fixedly connected to the side wall of the pressure rod.

[0016] As a further improvement of the technical solution, the connecting member is a straight rod whose bottom end is fixedly connected to the pressure rod and whose top end longitudinally penetrates into the discharge pipe. The top end of the straight rod is fixedly connected to a receiving plate, and the receiving plate is in an inclined state. A compression spring is provided between the bottom of the receiving plate and the side wall of the discharge pipe to elastically connect the two.

[0017] The middle part of the discharge pipe is in a bent state, and the bent state is above the movable knife.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the kitchen waste crushing and processing device, the kitchen waste with a smaller volume can be directly dropped under the crushing mechanism through the guidance of the first channel and the second channel, avoiding contact with the crushing mechanism, thereby reducing the working intensity of the crushing mechanism, and at the same time reducing the garbage in contact with the crushing mechanism, avoiding the crushing mechanism from being in a dirty state.

[0020] 2. In the kitchen waste crushing and processing device, the crushing mechanism can also drive the filter plate to shake during operation, so that the kitchen waste on the top of the filter plate can be quickly filtered, thereby speeding up the processing of the kitchen waste.

[0021] 3. In the kitchen waste crushing and processing device, during the crushing process of larger garbage, the inertia of the garbage in the discharge pipe or the movement of the driven rod drives the pressure rod to make longitudinal reciprocating motion, so that the pressure rod can press the garbage on the moving knife downward, making the garbage close to the side wall of the moving knife, thereby improving the crushing efficiency of larger garbage.

In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] See also Figure 1 and Figure 2 As shown, a kitchen waste crushing and processing device is provided, including a shell 100, and a filter plate 110 and a crushing mechanism arranged in the shell 100, wherein the top of the shell 100 has a top cover 101, and the bottom has a bottom cover 102; the crushing mechanism is located below the filter plate 110, and is used to crush the garbage; then, it also includes a first channel and a second channel, the first channel is located below the filter plate 110, and is used to guide the garbage filtered by the filter plate 110 to the bottom of the crushing mechanism; the second channel is located between the crushing mechanism and the filter plate 110, and is used to guide the unfiltered garbage on the top of the filter plate 110 to the crushing mechanism for crushing by the crushing mechanism.

[0036] The kitchen waste crushing and processing device disclosed in the present invention, through the guidance of the first channel and the second channel, allows the originally small kitchen waste to fall directly under the crushing mechanism, avoiding contact with the crushing mechanism, thereby reducing the working intensity of the crushing mechanism, and at the same time reducing the garbage in contact with the crushing mechanism, avoiding the crushing mechanism from being in a dirty state.

[0037] It can be understood that the top cover 101 and the bottom cover 102 are connected to the housing 100 in a rotational manner, and two hydraulic rods 103 are arranged on the outer ring of the housing 100, one of which is hinged to the top cover 101, and the other is hinged to the bottom cover 102. In this way, the opening and closing of the top cover 101 and the bottom cover 102 can be controlled by controlling the extension and contraction of the hydraulic rods 103.

[0038] The crushing mechanism includes two main shafts 120 penetrating the housing 100 , motors 122 are disposed at the ends of the two main shafts 120 , and movable knives 121 are disposed at the parts of the two main shafts 120 located inside the housing 100 .

[0039] In the above, the filter plate 110 is elastically arranged on the inner wall of the shell 100, and a driving device is arranged between the filter plate 110 and the crushing mechanism. The driving device drives the filter plate 110 to shake through the movement of the crushing mechanism, so that the filter plate 110 guides the unfiltered garbage on the top to the entrance of the second channel.

[0040] like Figure 3 As shown, in some embodiments:

[0041] A connecting spring 111 is provided between the outer ring of the filter plate 110 and the inner ring of the housing 100 to elastically connect the two.

[0042] A second material receiving hopper 140 is fixedly provided on the inner wall of the filter plate 110. The second material receiving hopper 140 is located above the movable knife 121. The outer diameter of the filter plate 110 is smaller than the inner diameter of the housing 100, so that a filtering channel 112 is formed between the outer ring of the filter plate 110 and the inner ring of the housing 100. The filtering channel 112 and the second material receiving hopper 140 together constitute a second channel.

[0043] The driving device includes a cam 141 sleeved on the outer ring of one of the main shafts 120, and a driven rod 142 located directly above the cam 141. The top end of the driven rod 142 passes through the second receiving hopper 140 and abuts against the bottom of the filter plate 110.

[0044] The first channel includes a first material receiving hopper 130 located below the filter plate 110 , the bottom end of the first material receiving hopper 130 is connected to a discharge pipe 131 , the bottom end of the discharge pipe 131 passes through the second material receiving hopper 140 , and one side of the bottom end of the first material receiving hopper 130 is fixedly connected to the inner wall of the shell 100 .

[0045] The working principle of the present invention is as follows:

[0046] First, pour the kitchen waste into the top of the shell 100 through the top of the shell 100, and then start the motor 122. The output shaft of the motor 122 drives the two main shafts 120 to rotate relative to each other, and the rotation of the main shaft 120 drives the two moving knives 121 to rotate relative to each other. At the same time, the rotating main shaft 120 will also drive the cam 141 to rotate, and the rotation of the cam 141 drives the driven rod 142 to perform longitudinal reciprocating motion on the second receiving hopper 140. During the upward movement of the driven rod 142, the top of the driven rod 142 abuts against the filter plate 110, causing the connecting spring 111 to deform to achieve the upward movement of the filter plate 110; during the upward movement of the driven rod 142, the driven rod 142 is separated from the bottom of the filter plate 110, and the filter plate 110 is reset by the deformation of the connecting spring 111, thereby generating shaking during the reset and upward movement.

[0047] Under the action of shaking, the filter plate 110 shakes the kitchen waste on the top, and the smaller kitchen waste falls into the first receiving hopper 130 through the filter holes on the top of the filter plate 110, and then is discharged to the bottom of the crushing mechanism through the discharge pipe 131 at the bottom of the first receiving hopper 130. The larger waste stays on the top of the filter plate 110, and then with the shaking of the top of the filter plate 110, the larger waste slowly moves to the edge of the filter plate 110, and then falls into the second receiving hopper 140 through the filter channel 112, and is guided to between the two moving knives 121 through the second receiving hopper 140, and the larger waste is crushed by the relative rotation of the two moving knives 121.

[0048] That is to say, the crushing mechanism can also drive the filter plate 110 to shake during operation, so that the kitchen waste on the top of the filter plate 110 can be quickly filtered, thereby speeding up the processing of the kitchen waste.

[0049] Moreover, in order to improve the filtering efficiency of the filter plate 110, the cam 141 and the driven rod 142 are both arranged at the two ends of the main shaft 120, and the angles between the two cams 141 at the two ends are different. In this way, during the rotation of the movable knife 121, the protruding end of the cam 141 at one end first pushes the driven rod 142 upward, and the driven rod 142 pushes one end of the filter plate 110 to tilt; then, the protruding end of the cam 141 at the other end pushes the driven rod 142 upward again, and the driven rod 142 pushes the other end of the filter plate 110 to tilt, so that the main shaft 120 can drive the filter plate 110 to move twice by rotating one circle.

[0050] like Figure 4As shown, in order to prevent the filter holes at the top of the filter plate 110 from being blocked by kitchen waste, a plurality of ejector pins 132 are fixedly arranged on the top of the first receiving hopper 130, and the plurality of ejector pins 132 are located below the filter holes at the top of the filter plate 110. In this way, when the filter plate 110 reciprocates, the ejector pins 132 can extend into the filter holes to eject the blockage in the filter holes, thereby achieving continuous filtering of the filter plate 110.

[0051] like Figure 5 A pressure rod 150 is provided in the second receiving hopper 140. The pressure rod 150 is located above the two movable knives 121. The pressure rod 150 is connected to a connecting piece for driving the pressure rod 150 to move downward to press down the kitchen waste above the movable knives 121.

[0052] In one embodiment, the connecting member is a connecting rod, and both ends of the pressing rod 150 penetrate the two sides of the second receiving hopper 140, one end of the connecting rod is fixedly arranged on the side wall of the driven rod 142, and the other end is fixedly connected to the side wall of the pressing rod 150. In this way, when the driven rod 142 is pushed by the cam 141 to perform reciprocating motion, the pressing rod 150 is driven by the connecting rod to perform longitudinal reciprocating motion, thereby pressing down the kitchen waste above the moving knife 121 during the longitudinal reciprocating motion to prevent the kitchen waste from being stuck above the moving knife 121.

[0053] In another embodiment, the connecting member is a straight rod 152 whose bottom end is fixedly connected to the pressure rod 150 and whose top end longitudinally penetrates into the discharge pipe 131. The middle part of the discharge pipe 131 has a bent state, and the bent state is above the movable knife 121. The top end of the straight rod 152 is fixedly connected to a receiving plate 151, and the receiving plate 151 is in an inclined state. A compression spring 153 is provided between the bottom of the receiving plate 151 and the side wall of the discharge pipe 131 to elastically connect the two. In this way, when the filtered garbage is discharged through the discharge pipe 131, during the discharge process, the garbage in the discharge pipe 131 will contact the receiving plate 151, and under the action of inertia, the garbage will press the receiving plate 151 to move downward, and the downward movement of the receiving plate 151 will drive the pressure rod 150 to move downward, and the downward movement of the pressure rod 150 will press down the garbage above the movable knife 121; when the garbage in the discharge pipe 131 is separated from the receiving plate 151, the compression spring 153 elastically pushes the receiving plate 151 to return to its original position, and the receiving plate 151 drives the pressure rod 150 to move upward and return to its original position through the straight rod 152.

[0054] In summary, in the process of crushing larger garbage, the inertia of the garbage in the discharge pipe 131 or the movement of the driven rod 142 drives the pressure rod 150 to make longitudinal reciprocating motion, so that the pressure rod 150 can press the garbage on the moving knife 121 downward, so that the garbage is close to the side wall of the moving knife 121, thereby improving the crushing efficiency of larger garbage.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
