[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] During specific implementation: As Figures 1-5 shown, a kitchen waste crushing device includes: a crushing box 1, the upper end of the inner wall of the crushing box 1 is rotatably connected with two crushing rollers 2, the top end of the crushing box 1 is fixedly connected with a feeding frame 3, and a crushing mechanism 4 is arranged inside the feeding frame 3; among them, the crushing mechanism 4 includes a mounting plate 41 slidably connected to the inner wall of the feeding frame 3, the bottom end of the mounting plate 41 is fixedly connected with a plurality of cylinders 42, the inner wall of the cylinder 42 is slidably connected with a round rod 43, the bottom ends of the plurality of round rods 43 penetrate out of the cylinder 42 and are fixedly connected with a fixed plate 45, a spring 44 is fixedly connected between the top end of the round rod 43 and the inner top wall of the cylinder 42, one side of the fixed plate 45 is fixedly connected with connecting plates 46 distributed in equal columns, a fixed rod 47 distributed in equal columns is fixedly connected between the opposite sides of adjacent two connecting plates 46, one side of the mounting plate 41 is fixedly connected with mounting rods 48 distributed in equal columns, and a plurality of cutting knives 49 are fixedly connected to the lower end of the surface of the mounting rod 48, and a trigger plate 410 is fixedly connected to the inner wall of the feeding frame 3.

[0025] One end of each of the two crushing rollers 2 penetrates out of the crushing box 1 and is fixed with a gear, the two gears are meshed and connected, one side of the crushing box 1 is fixedly connected with a second motor, and one end of one of the crushing rollers 2 penetrates out of the crushing box 1 and is fixedly connected with the output shaft of the second motor. When the second motor is started through the controller, the two crushing rollers 2 will be driven to rotate in opposite directions to crush the garbage under the action of the two gears, and a filter plate identical to the original scheme is arranged at the lower end of the inner wall of the crushing box 1 to separate the solid and liquid of the crushed garbage.

[0026] Under the action of multiple fixed rods 47, the space between two adjacent connecting plates 46 is spaced apart, so that a plurality of blanking ports are formed between two adjacent connecting plates 46. The number of cutting knives 49 is the same as the number of blanking ports, and the cutting knives 49 are located above the midpoints of the blanking ports.

[0027] As Figure 3 and Figure 4 As shown in FIGS. Figure 3 and Figure 4 , the crushing mechanism 4 further includes a first motor 411 fixedly connected to the top end of the crushing box 1. The output shaft of the first motor 411 is fixedly connected with a circular plate 412. The other end of the circular plate 412 is fixedly connected with a sliding rod 413. A sliding frame 414 is slidably connected to the surface of the sliding rod 413. The other side of the mounting plate 41 is fixedly connected with a sliding plate 415. The other side of the sliding plate 415 penetrates through the feeding frame 3 and is fixedly connected with one side of the sliding frame 414.

[0028] When crushing kitchen waste, the waste is poured into the feeding frame 3. At this time, some smaller waste will enter the crushing box 1 through a plurality of blanking ports. At this time, the two crushing rollers 2 are driven to rotate to crush the waste. At the same time, a plurality of connecting plates 46 will block the waste with larger fibers. At this time, the first motor 411 is started by the controller to drive the circular plate 412 to rotate. Since the sliding rod 413 is arranged at an eccentric position of the circular plate 412, and the inner top wall and the inner bottom wall of the sliding frame 414 always contact the surface of the sliding rod 413, when the circular plate 412 rotates, the sliding rod 413 will drive the sliding frame 414 to move up and down reciprocally, and drive the mounting plate 41 to move up and down reciprocally synchronously through the sliding plate 415, so as to drive the mounting rod 48, the cylinder 42, the round rod 43, the fixing plate 45, and the connecting plate 46 to move up and down reciprocally synchronously, so that the smaller waste in the feeding frame 3 can be discharged better through the blanking ports, and the waste with larger fibers can be better aggregated on the connecting plate 46. At the same time, when the mounting plate 41 drives the fixing plate 45, the connecting plate 46 to move downward through the cylinder 42, the round rod 43 and the spring 44, when the bottom end of the fixing plate 45 contacts the top end of the trigger plate 410, the fixing plate 45 and the connecting plate 46 cannot move downward. At this time, the mounting plate 41 will drive the mounting rod 48 and the cutting knife 49 to continue to move downward, and compress the spring 44. The cutting knife 49 continues to move downward to cut the larger fiber waste intercepted by the connecting plate 46. During the process of the mounting plate 41 driving the fixing plate 45 to move up and down reciprocally, the cutting knife 49 will continuously cut the intercepted waste.

[0029] As Figure 3 and Figure 5As shown, a guide plate 416 is fixedly connected to the top end of the connecting plate 46. The vertical section of the guide plate 416 is an isosceles triangle, and grooves 417 are provided at equal intervals at the top end of the guide plate 416. When the connecting plate 46 intercepts longer fiber waste, the waste will stay on two adjacent guide plates 416, and part of the limit will be stuck in the grooves 417.

[0030] As Figure 3 shown, a guide plate 418 is fixedly connected to one side of the inner wall of the feeding frame 3. The guide plate 418 is inclined. The guide plate 418 is arranged above the mounting plate 41.

[0031] As Figure 4 shown, equally spaced convex blocks 419 are fixedly connected to the upper end of the surface of the mounting rod 48. The overall shape of the convex blocks 419 is conical. When the mounting plate 41 drives the mounting rod 48 to move up and down, a plurality of convex blocks 419 will be driven to move up and down synchronously, and the plurality of convex blocks 419 will disperse the waste above the mounting rod 48.

[0032] As Figure 4 shown, a protective rod 420 is fixedly connected to the top end of the mounting plate 41. The vertical section of the protective rod 420 is a right triangle. One side of the vertical plane of the protective rod 420 is in contact with the inner wall of the feeding frame 3.

[0033] As Figure 4 shown, a baffle 421 is fixedly connected to the surface of the sliding plate 415. One side of the baffle 421 is attached to one side of the feeding frame 3. A chute matching the sliding plate 415 is provided on one side of the feeding frame 3, and the size of the baffle 421 is larger than the size of the chute.

[0034] When the utility model is in use and the kitchen waste is crushed, the waste is poured into the feeding frame 3. At this time, some smaller waste will enter the crushing box 1 through multiple feeding ports. At this time, the two crushing rollers 2 are driven to rotate to crush the waste. At the same time, multiple connecting plates 46 will block the waste with larger fibers. At this time, the controller starts the first motor 411 to drive the circular plate 412 to rotate, so that the sliding rod 413 drives the sliding frame 414 to move up and down reciprocally, and drives the mounting plate 41, the mounting rod 48, the cylinder 42, the round rod 43, the fixing plate 45, and the connecting plate 46 to move up and down reciprocally synchronously through the sliding plate 415. During the up and down reciprocating movement, the smaller waste in the feeding frame 3 can be discharged better through the feeding ports, and the waste with larger fibers can be better aggregated on the connecting plate 46. At the same time, when the mounting plate 41 drives the fixing plate 45, the cylinder 42, the round rod 43, and the spring 44 to drive the fixing plate 45 and the connecting plate 46 to move downward, when the bottom end of the fixing plate 45 contacts the top end of the trigger plate 410, the fixing plate 45 and the connecting plate 46 cannot move downward. At this time, the mounting plate 41 will drive the mounting rod 48 and the cutting knife 49 to continue to move downward, and compress the spring 44. The continuous downward movement of the cutting knife 49 will cut the larger fiber waste intercepted by the connecting plate 46. During the process of the mounting plate 41 driving the fixing plate 45 to move up and down reciprocally, the cutting knife 49 will continuously cut the intercepted waste.

[0035] It should be noted that in the above description, the first motor 411 and the second motor are both devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the first motor 411 and the second motor can be powered by an internal power supply or by the mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard this specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
