[0077] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0078] See also Figures 1 to 5 The utility model provides a crushing device, which is connected to a garbage storage box. One side of the garbage storage box is open, including: a rear door 1, a crushing member 2, a baffle 3 and a driving member 4. The rear door 1 is arranged relative to the opening and is hinged with the garbage storage box for opening or blocking the opening. The rear door 1 is formed with a crushing chamber 11 connected to the interior of the garbage storage box and a discharge port 12 connected to the crushing chamber 11. The crushing member 2 is connected to the inner wall of the crushing chamber 11 for crushing garbage. The baffle 3 is arranged relative to the discharge port 12 and can slide relative to the rear door 1. The driving member 4 is connected to the rear door 1 and is connected to the baffle 3 for driving the baffle 3 to slide relative to the rear door 1 to open or close the discharge port 12.

[0079] In the present device, a rear door 1 is hinged at the open end of the garbage storage box for opening or blocking the opening, a crushing member 2 is connected to the inner wall of the crushing chamber 11 for crushing the garbage, a baffle 3 is arranged relative to the discharge port 12 and can slide relative to the rear door 1, and a driving member 4 is connected to the rear door 1 and the baffle 3 for driving the baffle 3 to slide relative to the rear door 1 so that the discharge port 12 is opened or closed.

[0080] Compared with the prior art, a crushing piece 2 and a baffle 3 are provided on the rear door 1, and the crushing piece 2 is used to crush the garbage in the garbage storage box and dump it from the discharge port 12, thereby avoiding dumping the garbage by opening the rear door 1 or manual cleaning. At the same time, the sliding of the baffle 3 relative to the rear door 1 can quickly open and close the discharge port 12, which is convenient for use and operation, saves time and effort, and can solve the technical problem in the prior art that the kitchen waste is complex and diverse in size and shape, which is prone to incomplete dumping and requires manual cleaning, thereby prolonging the operation time.

[0081] Furthermore, the rear door 1 is hinged at the opening of the garbage storage box. When in use, the garbage in the garbage storage box can be dumped or cleaned by opening the rear door 1. This is a conventional setting known to those skilled in the art. In this device, the rear door 1 supports and connects the crushing member 2, the baffle 3 and the driving member 4.

[0082] Furthermore, a pushing assembly is also provided inside the garbage storage box. The garbage thrown into or poured into the garbage storage box is pushed to the rear door 1 by the pushing assembly, which can compress the volume of the garbage. At the same time, the garbage pushed to the rear door 1 enters the feeding chamber 13 and is transported to the crushing chamber 11 for crushing through the spiral feeding member 6. The pushing assembly here belongs to a conventional setting well known to those skilled in the art and will not be described in detail.

[0083] Furthermore, since food waste usually contains liquid pollutants such as water and oil, and in order to reduce the overflow of odor in the garbage storage box, a seal is also provided between the rear door 1 and the open end of the garbage storage box. The device breaks up the sharp objects contained in the food waste by providing a crushing member 2, thereby preventing the sharp objects from damaging the seal.

[0084] like Figure 1 As shown, a groove is formed relative to the opening of the rear door 1, and the crushing device also includes a surrounding plate 5 and a spiral feeding member 6. The surrounding plate 5 is connected to the inner wall of the groove and divides the groove into a crushing chamber 11 and a feeding chamber 13 spaced apart from each other. The surrounding plate 5 is provided with a connecting hole, which is connected to the feeding chamber 13 and the crushing chamber 11. The spiral feeding member 6 is rotatably built into the feeding chamber 13 and is used to transport materials in a direction close to the connecting hole.

[0085] The groove on the rear door 1 is divided into two independent crushing chambers 11 and feeding chambers 13 by the enclosure 5, and the crushing chamber 11 and the feeding chamber 13 are connected by a connecting hole. By setting a spiral feeding piece 6, the garbage in the feeding chamber 13 can be transported to the crushing chamber 11 for crushing.

[0086] Furthermore, the spiral feeding member 6 is a common device on the market, which includes a rotating main shaft 61 and a second feeding blade 62. The second feeding blade 62 is spiral-shaped. The second feeding blade 62 is extended along the axial direction of the rotating main shaft 61 and is connected to the rotating main shaft 61, wherein the connecting hole is connected to the discharge end of the spiral feeding member 6. Here, the spiral feeding member 6 belongs to a conventional setting known to those skilled in the art and will not be described in detail.

[0087] As an implementation method, Figure 1 , Figure 4 As shown, the discharge port 12 is arranged on the side of the crushing chamber 11 away from the connecting hole, and the crushing member 2 includes a first rotating shaft 21, two first feeding blades 22 and a crushing part 23. The axis of the first rotating shaft 21 is arranged perpendicular to the axis of the connecting hole and is rotatably connected to the inner wall of the crushing chamber 11. The two first feeding blades 22 are arranged at intervals from each other and are both connected to the first rotating shaft 21 for conveying materials along the axial direction of the first rotating shaft 21. The crushing part 23 is arranged between the two first feeding blades 22 and is connected to the first rotating shaft 21 for crushing materials.

[0088] The first rotating shaft 21 and the two first feeding blades 22 form a structure similar to a spiral feeder, which can transport materials along a specified direction, wherein a crushing part 23 is arranged between the two first feeding blades 22, which can crush the garbage and then transport it to the discharge port 12.

[0089] Furthermore, by respectively arranging the connecting hole and the discharge port 12 at the two ends of the first rotating shaft 21, the movement of the garbage in the crushing chamber 11 can be increased. Specifically, the crushing part 23 in the present device is a crusher that is common and easy to purchase on the market. The crusher here belongs to a conventional setting known to those skilled in the art and will not be described in detail.

[0090] Furthermore, the crushing element 2 in the present device also includes a third feeding blade 24, and the rotation direction of the third feeding blade 24 is opposite to that of the first feeding blade 22. The third feeding blade 24 is arranged on the other side of the discharge port 12 away from the first feeding blade 22, and is connected to the first rotating shaft 21. The rotation directions of the first feeding blade 22 and the third feeding blade 24 are opposite, which can facilitate the discharge of garbage from the discharge port 12.

[0091] As a preferred implementation method, Figures 1 to 5As shown, the crushing member 2 also includes an outer shell 25, which is cylindrical and coaxially arranged with the first rotating shaft 21. The outer shell 25 is sleeved on the first rotating shaft 21, the two first feeding blades 22 and the crushing part 23, and is fixedly connected to the inner wall of the crushing chamber 11. The outer shell 25 is provided with a feed port relative to the connecting hole, and the feed port is connected with the connecting hole and the interior of the outer shell 25. The outer shell 25 is provided with a discharge port relative to the discharge port 12, and the discharge port is connected with the discharge port 12 and the interior of the outer shell 25.

[0092] like Figure 2 As shown, the device also includes a flange connection seat 7, a connecting rod 8 and a baffle mounting seat 9. The interior of the flange connection seat 7 is hollow and is connected to the discharge port 12. The flange connection seat 7 is provided with a through groove. The connecting rod 8 is L-shaped, and one end of the connecting rod 8 is transmission-connected to the driving member 4. The baffle mounting seat 9 is arranged relative to the through groove and is connected to the other end of the connecting rod 8. The baffle 3 is slidably inserted in the through groove and connected to the baffle mounting seat 9.

[0093] The flange connection seat 7 is used to improve the sealing between the rear door 1 and the discharge port 12, the baffle mounting seat 9 is used to support and connect the baffle 3, and the connecting rod 8 is used to transmit the driving force of the driving member 4 to the baffle mounting seat 9, thereby realizing the sliding of the baffle 3 relative to the flange connection seat 7.

[0094] Furthermore, the flange connection seat 7 and the baffle mounting seat 9 are conventional arrangements well known to those skilled in the art, and will not be described in detail herein.

[0095] like Figure 1 As shown, the driving member 4 includes a driving motor 41 , a first transmission part 42 and an adjustment part 43 , a cam part 44 , and a second transmission part 45 .

[0096] Among them, the fixed end of the driving motor 41 is connected to the rear door 1, one end of the first transmission part 42 is transmission connected to the output shaft of the driving motor 41, the adjusting part 43 is slidably connected to the rear door 1, and can be transmission connected to the connecting rod 8 and one end of the first transmission part 42, for driving the baffle 3 to slide into or out of the through groove to close or open the discharge port 12.

[0097] The rotation of the driving motor 41 can be converted and transmitted to the connecting rod 8 and the baffle plate 3 through the first transmission part 42 and the adjustment part 43 , so that the connecting rod 8 and the baffle plate 3 slide relative to the flange connection seat 7 .

[0098] As an implementation method, Figure 3 , Figure 5As shown, the first transmission part 42 includes a rotating bearing 421, a transmission shaft 422 and two bevel gears 423. The rotating bearing 421 is connected to the rear door 1. The axis of the bearing hole of the rotating bearing 421 is perpendicular to the axis of the first rotating shaft 21. The transmission shaft 422 is inserted into the bearing hole of the rotating bearing 421 and can rotate relative to the rear door 1. A bevel gear 423 is fixedly sleeved on the transmission shaft 422, and the other bevel gear 423 is fixedly sleeved on the output shaft of the driving motor 41 and meshes with a bevel gear 423.

[0099] The rotating bearing 421 connects the rotation between the transmission shaft 422 and the rear door 1. The transmission structure formed by the transmission shaft 422 and the two bevel gears 423 changes the rotation axis of the motor to a direction perpendicular to its axis, thereby driving the adjustment part 43 to be connected with the connecting rod 8 in transmission.

[0100] As a preferred implementation method, Figures 5 to 8 As shown, the adjusting portion 43 includes a rack 431, a first gear 432, a fixed seat 433, two sliding plates 434, a second rotating shaft 435, a third rotating shaft 436, at least one second gear 437 and two third gears 438. The rack 431 is arranged along the extension direction of the connecting rod 8 and is connected to the connecting rod 8. The first gear 432 is fixedly sleeved on the transmission shaft 422. The fixed seat 433 is spaced apart from the transmission shaft 422 and is fixedly connected to the rear door 1. The fixed seat 433 has a sliding groove relative to the rack 431. The two sliding plates 434 are spaced apart from each other. , and are both slidably connected to the slide groove, the second rotating shaft 435 and the third rotating shaft 436 are arranged at intervals, and the two ends of the second rotating shaft 435 and the third rotating shaft 436 are respectively connected and rotatably connected to the two sliding plates 434, the second gear 437 is fixedly sleeved on the second rotating shaft 435, and can be engaged with the first gear 432 or the rack 431, the two third gears 438 are arranged at intervals, and are both fixedly sleeved on the third rotating shaft 436, and one third gear 438 is engaged with the second gear 437, and the other third gear 438 can be engaged with the rack 431.

[0101] Two sliding plates 434, a second rotating shaft 435, a third rotating shaft 436, at least one second gear 437 and two third gears 438 can form a gear set. The gear set slides relative to the fixed seat 433 and can be lifted and lowered relative to the first gear 432. After sliding, the gear set has a first state, a second state and a third state. The gear set realizes the normal closure, the transition from closed to open, and the transition from open to closed of the discharge valve in the three states.

[0102] As a preferred implementation method, Figures 6 to 8As shown, the number of the second gear 437 is one, and the thickness of the second gear 437 is twice that of the third gear 438. Specifically, the gear set is in the initial state in the first state. At this time, the first gear 432 cannot contact the second gear 437, the third gear 438 and the rack 431. At this time, the baffle 3 cannot slide relative to the flange connection seat 7, and the discharge valve is normally closed.

[0103] Furthermore, if Figure 7 As shown, after the gear set rises by the thickness of the third gear 438 relative to the first gear 432, the gear set is in the second state. At this time, the first gear 432 can mesh with the second gear 437, and the second gear 437 is also meshed with the rack 431. The driving motor 41 rotates, which can drive the rack 431 and the connecting rod 8 to slide relative to the flange connection. At this time, the discharge port 12 gradually opens to be fully opened. At this time, although the second gear 437 can mesh with the third gear 438 located at a high position, the rack 431 does not contact it.

[0104] Furthermore, if Figure 8 As shown, after the gear set continues to rise by the thickness of the third gear 438 relative to the first gear 432, the gear set is in the third state, and the third gear 438 located at the lower position is at the same height as the rack 431 and can mesh with each other. At the same time, since the thickness of the second gear 437 is twice that of the third gear 438, the second gear 437 can also mesh with the first gear 432 and the third gear 438 located at the higher position at the same time, thereby transmitting the driving force of the first gear 432 to the third gear 438 located at the lower position, and driving the rack 431 and the connecting rod 8 to move. At this time, the discharge port 12 gradually closes to be completely closed.

[0105] As an implementation method, Figure 2 , Fig. 9 As shown, the cam portion 44 includes a cam 441, a fourth rotating shaft 442 and a hand crank handle 443. The cam 441 is arranged below the sliding plate 434 and can abut against a sliding plate 434. The fourth rotating shaft 442 is rotatably connected to the rear door 1, and one end of the fourth rotating shaft 442 is coaxially arranged with the cam 441 and connected to the cam 441. The hand crank handle 443 is connected to the other end of the fourth rotating shaft 442.

[0106] When in use, by rotating the hand crank handle 443, the cam 441 can be driven to rotate around the axis of the fourth rotating shaft 442. The rotated cam 441 can continuously abut against the sliding plate 434, thereby pushing the gear set to slide relative to the fixed seat 433, thereby adjusting the meshing of different gears with the rack 431.

[0107] Specifically, Fig. 9As shown, the cam 441 in the present device has a first abutting surface 4411, a second abutting surface 4412 and a third abutting surface 4413. The first abutting surface 4411, the second abutting surface 4412 and the third abutting surface 4413 of the cam 441 can respectively abut against the sliding plate 434, thereby switching between the first state, the second state and the third state.

[0108] As another implementation method, Figure 3 As shown, the second transmission part 45 includes a first transmission gear 451, a second transmission gear 452, at least one first transmission sprocket 453, at least one second transmission sprocket 454 and at least one chain 455. The first transmission gear 451 is fixedly mounted on the first rotating shaft 21, the second transmission gear 452 is fixedly mounted on the output shaft of the driving motor 41 and meshes with the first transmission gear 451, the first transmission sprocket 453 is coaxially arranged with the spiral feeding member 6 and fixedly mounted on the rotating shaft of the spiral feeding member 6, the second transmission sprocket 454 is arranged in a one-to-one correspondence with the first transmission sprocket 453, and is fixedly mounted on the output shaft of the driving motor 41, the chain 455 is arranged in a one-to-one correspondence with the second transmission sprocket 454, and the chain 455 is meshed with both the first transmission sprocket 453 and the second transmission sprocket 454.

[0109] Through the first transmission gear 451, the second transmission gear 452, at least one first transmission sprocket 453, at least one second transmission sprocket 454 and at least one chain 455, the spiral feeding member 6 and the first rotating shaft 21 can rotate around their axes respectively, so that one driving motor 41 can drive three execution structures to move at the same time.

[0110] Furthermore, in the present device, the number of the first transmission sprocket 453, the number of the second transmission sprocket 454 and the chain 455 are two respectively, so as to improve the stability of motion transmission.

[0111] The utility model also provides a restaurant kitchen garbage truck, comprising a garbage storage box and a crushing device.

[0112] The garbage storage box and the crushing device are both connected to the body of the vehicle, thereby forming a food garbage truck.

[0113] The specific working process of the utility model is as follows: the rear door 1 is hinged to the open end of the garbage storage box, and is used to open or block the opening; the crushing member 2 is connected to the inner wall of the crushing chamber 11, and is used to crush the garbage; the baffle 3 is arranged relative to the discharge port 12, and can slide relative to the rear door 1; the driving member 4 is connected to the rear door 1 and the baffle 3, and is used to drive the baffle 3 to slide relative to the rear door 1, so that the discharge port 12 is opened or closed. Compared with the prior art, by arranging the crushing member 2 and the baffle 3 on the rear door 1, the crushing member 2 is used to crush the garbage in the garbage storage box, and dump it from the discharge port 12, avoiding dumping the garbage by opening the rear door 1 or manual cleaning, and at the same time, by sliding the baffle 3 relative to the rear door 1, the discharge port 12 can be opened and closed quickly, which is convenient for use and operation, saving time and effort.

[0114] When in use, after the kitchen waste is put into or poured into the garbage storage box, it enters the feeding chamber 13 under the pushing action of the pushing assembly. As the spiral conveyor continues to rotate, the garbage enters the crushing chamber 11 through the connecting hole and is crushed under the action of the crushing part 23. Finally, the garbage can be dumped by controlling the opening or closing of the discharge port 12.

[0115] Furthermore, the gear set is in the initial state in the first state, the first gear 432 cannot contact the second gear 437, the third gear 438 and the rack 431, and the baffle 3 cannot slide relative to the flange connection seat 7, and the discharge valve is normally closed.

[0116] Furthermore, if Figures 6 to 8 As shown, after the gear set rises by the thickness of the third gear 438 relative to the first gear 432, the gear set is in the second state. At this time, the first gear 432 can mesh with the second gear 437, and the second gear 437 is also meshed with the rack 431. The driving motor 41 rotates, which can drive the rack 431 and the connecting rod 8 to slide relative to the flange connection. At this time, the discharge port 12 gradually opens to be fully opened. At this time, although the second gear 437 can mesh with the third gear 438 located at a high position, the rack 431 does not contact it.

[0117] Furthermore, if Figures 6 to 8 As shown, after the gear set continues to rise by the thickness of the third gear 438 relative to the first gear 432, the gear set is in the third state, and the third gear 438 located at the lower position is at the same height as the rack 431 and can mesh with each other. At the same time, since the thickness of the second gear 437 is twice that of the third gear 438, the second gear 437 can also mesh with the first gear 432 and the third gear 438 located at the higher position at the same time, thereby transmitting the driving force of the first gear 432 to the third gear 438 located at the lower position, and driving the rack 431 and the connecting rod 8 to move. At this time, the discharge port 12 gradually closes to be completely closed.

[0118] The device, through the above structure, can solve the technical problem in the prior art that kitchen waste is prone to incomplete dumping due to its complex and diverse volume and shape, requiring manual assistance for cleaning, thereby prolonging the operation time.

[0119] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
