Description

Technical Field

[0001] The utility model relates to the technical field of restaurant and kitchen waste treatment, in particular to a restaurant and kitchen waste crushing device. Background Art

[0002] In the winter in the north, the reception of food waste is very special. Since many garbage cans are frozen outdoors, after the food waste truck transports these frozen food waste to the food waste treatment production line, these whole pieces of frozen food waste cannot be directly dumped into the receiving bucket of the production line, making it very difficult to handle. Frozen food waste in the north in winter is large in size, difficult to crush, and the working environment is very harsh. At present, people use hot water to rinse frozen food waste to thaw it, but the processing efficiency is low and people are easily scalded. Utility Model Content

[0003] In order to solve the technical problem that people use hot water to rinse frozen food waste to thaw it, which not only has low processing efficiency but also easily causes burns, the utility model provides a food waste crushing device, which replaces people manually using hot water to thaw the frozen food waste, has a high degree of automation, and effectively improves the processing efficiency of the frozen food waste.

[0004] The utility model provides a kitchen waste crushing device, comprising a frame, a driving mechanism and a crushing mechanism, wherein the driving mechanism comprises a driving assembly and an adjusting assembly, and the crushing mechanism comprises a fixed wear-resistant plate and a dynamic wear-resistant plate, wherein the fixed wear-resistant plate is fixedly arranged inside the frame, the top of the dynamic wear-resistant plate is slidably arranged inside the frame through the driving assembly, the bottom of the dynamic wear-resistant plate is slidably arranged inside the frame through the adjusting assembly, and the dynamic wear-resistant plate reciprocates relative to the fixed wear-resistant plate; a feed port is formed between the top of the fixed wear-resistant plate and the top of the dynamic wear-resistant plate, a crushing zone is formed between the middle of the fixed wear-resistant plate and the middle of the dynamic wear-resistant plate, and a discharge port is formed between the bottom of the fixed wear-resistant plate and the bottom of the dynamic wear-resistant plate, and the feed port, the crushing zone and the discharge port are sequentially connected. The material descends through the feed port into the crushing zone by its own weight, and the material with a diameter less than 100 mm directly passes through the crushing zone to the discharge port, and finally enters the next station through the discharge port to wait for processing. Materials with a diameter greater than 100mm will stay in the crushing area for crushing. The driving component and the adjusting component work together to make the dynamic wear-resistant plate reciprocate relative to the fixed wear-resistant plate. The materials in the crushing area begin to be crushed by the squeezing of the dynamic wear-resistant plate and the fixed wear-resistant plate until their diameter is less than 100mm. Then they enter the next workstation from the discharge port to wait for processing.

[0005] Furthermore, the driving assembly includes a driving motor, an eccentric crankshaft and a driving belt. The driving motor is arranged outside the frame and the output shaft of the driving motor is connected to the first pulley. The eccentric crankshaft is rotatably arranged on the frame and the two ends of the crankshaft are respectively provided with a second pulley and an inertia wheel. The eccentric crankshaft is fixedly connected to the top of the dynamic wear-resistant plate, and the driving belt is wound around the first pulley and the second pulley. When the driving motor is started, it drives the first pulley to rotate, and then drives the second pulley and the belt to rotate, and the eccentric crankshaft is then rotated. The inertia wheel supports the eccentric crankshaft and assists the eccentric crankshaft to move smoothly. Since the eccentric crankshaft is fixedly connected to the top of the dynamic wear-resistant plate, the thrust generated by the vibration of the eccentric crankshaft will drive the dynamic wear-resistant plate to reciprocate, thereby squeezing and crushing the frozen food waste to break it.

[0006] Furthermore, the adjustment assembly includes a first bolt and a second bolt, a fixing frame is provided inside the frame, and the fixed wear-resistant plate and the dynamic wear-resistant plate are located on one side of the fixing frame, one end of the first bolt is provided on the fixing frame, and the other end of the first bolt is connected to the bottom of the dynamic wear-resistant plate through a first adjusting member; one end of the second bolt is provided on the fixing frame through a second adjusting member, and a through hole is provided on the fixing frame, and the other end of the second bolt passes through the through hole and is connected to the bottom of the dynamic wear-resistant plate. When the eccentric crankshaft drives the top of the dynamic wear-resistant plate to move, the first bolt mainly plays a thrust role, so that the bottom of the dynamic wear-resistant plate moves with the top of the dynamic wear-resistant plate, and the dynamic wear-resistant plate realizes reciprocating motion relative to the fixed wear-resistant plate. The second bolt generates a pulling force on the dynamic wear-resistant plate, thereby limiting the bottom movement position of the dynamic wear-resistant plate, thereby preventing the bottom of the dynamic wear-resistant plate from moving irregularly.

[0007] Furthermore, the first adjusting member includes a first connecting rod, the first bolt and the bottom of the dynamic wear-resistant plate are both provided with a first bearing seat, a spherical sliding bearing is rotatably provided in each of the first bearing seats, and the two ends of the first connecting rod are respectively connected to the two spherical sliding bearings. The first connecting rod drives the bottom of the dynamic wear-resistant plate to move following the top of the dynamic wear-resistant plate, and the dynamic wear-resistant plate realizes reciprocating motion relative to the fixed wear-resistant plate.

[0008] Furthermore, a threaded hole is provided on the fixing frame and an internal thread is provided in the threaded hole, an external thread matching the internal thread is provided on the first bolt, and one end of the first bolt away from the first bearing seat passes through the threaded hole and is locked on the fixing frame through the external thread and the internal thread.

[0009] Furthermore, the second adjusting member includes a spring, the spring is wound around one end of the second bolt away from the bottom of the dynamic wear-resistant plate, and the two ends of the spring are respectively connected to the second bolt and the fixing frame. The spring limits the second bolt, thereby limiting the bottom movement position of the dynamic wear-resistant plate, thereby preventing the bottom of the dynamic wear-resistant plate from moving without rules.

[0010] Furthermore, a plurality of protruding teeth are arranged on the end surface of the fixed wear-resistant plate close to the dynamic wear-resistant plate and the end surface of the dynamic wear-resistant plate close to the fixed wear-resistant plate. The protruding teeth are designed to increase local pressure, so that the frozen food waste is unevenly stressed and is easier to break.

[0011] Furthermore, it also includes a receiving bucket arranged inside the frame, and the receiving port of the receiving bucket is located below the discharge port. Frozen kitchen waste with a diameter less than 100 mm enters the receiving bucket through the discharge port, and the receiving bucket temporarily collects the waste and waits for subsequent equipment to process it.

[0012] Compared with the prior art, the utility model has the following technical effects:

[0013] The overall structure of the food waste crushing equipment is simple and compact. It relies on the force generated by the relative movement of the fixed wear-resistant plate and the dynamic wear-resistant plate to crush the frozen food waste, replacing the manual use of hot water to thaw the frozen food waste, effectively reducing labor consumption and improving the working environment; the high degree of automation effectively improves the processing efficiency of frozen food waste. In addition, the frozen food waste is broken into small pieces, providing the necessary production conditions for subsequent equipment, making it no longer difficult for subsequent equipment to process frozen food waste, effectively reducing the load of downstream equipment, and further improving the processing efficiency of frozen food waste.

[0025] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figures 1 to 5As shown, a kitchen waste crushing device includes a frame 1, a driving mechanism and a crushing mechanism 2, wherein the driving mechanism includes a driving assembly 3 and an adjusting assembly 4, and the crushing mechanism 2 includes a fixed wear-resistant plate 21 and a movable wear-resistant plate 22, wherein the fixed wear-resistant plate 21 is fixedly arranged inside the frame 1, and the top of the movable wear-resistant plate 22 is slidably arranged inside the frame 1 through the driving assembly 3, and the bottom of the movable wear-resistant plate 22 is slidably arranged inside the frame 1 through the adjusting assembly 4, and the movable wear-resistant plate 2 2 reciprocates relative to the fixed wear-resistant plate 21, specifically, the movable wear-resistant plate 22 slides left and right relative to the fixed wear-resistant plate 21; a feed port 23 is formed between the top of the fixed wear-resistant plate 21 and the top of the movable wear-resistant plate 22, a crushing zone 24 is formed between the middle of the fixed wear-resistant plate 21 and the middle of the movable wear-resistant plate 22, and a discharge port 25 is formed between the bottom of the fixed wear-resistant plate 21 and the bottom of the movable wear-resistant plate 22; wherein, the feed port 23, the crushing zone 24 and the discharge port 25 are sequentially connected. The material (frozen kitchen waste) is dumped into the kitchen waste crushing equipment of this embodiment by the kitchen waste transport vehicle. Specifically, the material descends through the feed port 23 into the crushing zone 24 by its own weight, and the material with a diameter less than 100 mm directly passes through the crushing zone 24 to the discharge port 25, and finally enters the next station through the discharge port 25 to wait for processing. Materials with a diameter greater than 100 mm stay in the crushing zone 24 for crushing processing. Specifically, the driving component 3 and the adjusting component 4 work together to make the dynamic wear-resistant plate 22 reciprocate relative to the fixed wear-resistant plate 21. The materials in the crushing zone 24 begin to be crushed by the squeezing of the dynamic wear-resistant plate 22 and the fixed wear-resistant plate 21 until their diameter is less than 100 mm. Then they enter the next workstation from the discharge port 25 to wait for processing.

[0027] The kitchen waste crushing equipment of this embodiment has a simple and compact overall structure. It relies on the force generated by the relative movement of the fixed wear-resistant plate 21 and the movable wear-resistant plate 22 to crush the frozen kitchen waste, instead of manually washing the frozen kitchen waste with hot water to thaw it, effectively reducing labor consumption and improving the working environment of people; the degree of automation is high, which effectively improves the processing efficiency of frozen kitchen waste. In addition, the frozen kitchen waste is broken into small pieces, providing the necessary production conditions for subsequent equipment (for example: pre-crushing the frozen kitchen waste for the subsequent conveyor and pulping equipment), making it no longer difficult for subsequent equipment to process the frozen kitchen waste, effectively reducing the load of downstream equipment, and further improving the processing efficiency of frozen kitchen waste.

[0028] As an implementable embodiment, the driving assembly 3 includes a driving motor 31, an eccentric crankshaft 32 and a driving belt 33, the driving motor 31 is arranged outside the frame 1 and the output shaft of the driving motor 31 is connected to the first pulley 311, the eccentric crankshaft 32 is rotatably arranged on the frame 1 and the two ends of the crankshaft are respectively provided with a second pulley 321 and an inertia wheel 322, the eccentric crankshaft 32 is fixedly connected to the top of the dynamic wear-resistant plate 22, and the driving belt 33 is wound around the first pulley 311 and the second pulley 321.

[0029] The eccentric crankshaft 32 of this embodiment is provided with a rotating bearing seat 333 at both ends, and the two rotating bearing seats 333 are located between the second pulley 321 and the inertia wheel 322. The two rotating bearing seats 333 are arranged on the frame 1 so that the eccentric crankshaft 32 can rotate on the frame 1. The driving motor 31 is started, driving the first pulley 311 to rotate, and then driving the second pulley 321 and the belt to rotate, and the eccentric crankshaft 32 is then rotated. The inertia wheel 322 supports the eccentric crankshaft 32 and assists the eccentric crankshaft 32 to move smoothly. The eccentric distance of the eccentric crankshaft 32 of this embodiment is 8mm, and it generates periodic vibration when it rotates. Since the eccentric crankshaft 32 is fixedly connected to the top of the dynamic wear-resistant plate 22, the thrust generated by this vibration drives the dynamic wear-resistant plate 22 to reciprocate, thereby squeezing and crushing the frozen food waste to break it. Among them, there is an 8mm change interval at the feed port 23. This embodiment is driven by only one driving motor 31, which has the advantage of low manufacturing cost.

[0030] As an implementable embodiment, the adjusting assembly 4 includes a first bolt 41 and a second bolt 42, a fixing frame 11 is provided inside the frame 1, and the fixed wear-resistant plate 21 and the dynamic wear-resistant plate 22 are located on one side of the fixing frame 11, one end of the first bolt 41 is provided on the fixing frame 11, a threaded hole is provided on the fixing frame 11, an internal thread is provided in the threaded hole, an external thread matching the internal thread is provided on one end of the first bolt 41, one end of the first bolt 41 is locked on the fixing frame 11 by the external thread and the internal thread, and the other end of the first bolt 41 is connected to the bottom of the dynamic wear-resistant plate 22 through a first adjusting member, wherein the first adjusting member includes a first connecting rod 411, and a first bearing seat 6 is provided on one end of the first bolt 41 away from the fixing frame 11 and the bottom of the dynamic wear-resistant plate 22, and a spherical sliding bearing 61 is rotatably provided in each of the first bearing seats 6, and the two ends of the first connecting rod 411 are respectively connected to the two spherical sliding bearings 61. The driving motor 31 is started to realize the rotation of the eccentric crankshaft 32, and the eccentric crankshaft 32 then drives the top of the dynamic wear-resistant plate 22 to move, and the bottom of the dynamic wear-resistant plate 22 moves with the top of the dynamic wear-resistant plate 22. At this time, the first bolt 41 mainly plays a thrust role. The thrust role means that the first bolt 41 is fixed, and the bottom of the dynamic wear-resistant plate 22 moves with the top of the dynamic wear-resistant plate 22 under the transmission action of the first connecting rod 411 connected to the first bolt 41, and the dynamic wear-resistant plate 22 realizes reciprocating motion relative to the fixed wear-resistant plate 21. One end of the second bolt 42 is arranged on the fixing frame 11 through a second adjusting member, and the second adjusting member includes a spring 421, wherein the spring 421 is wound on one end of the second bolt 42 away from the bottom of the dynamic wear-resistant plate 22, and the two ends of the spring 421 are respectively connected to the second bolt 42 and the fixing frame 11; a through hole is provided on the fixing frame 11 and the through hole is located below the threaded hole, and the other end of the second bolt 42 passes through the through hole and is connected to the bottom of the dynamic wear-resistant plate 22. When the eccentric crankshaft 32 drives the top of the dynamic wear-resistant plate 22 to move, the first connecting rod 411 drives the bottom of the dynamic wear-resistant plate 22 to move following the top of the dynamic wear-resistant plate 22. At this time, the spring 421 limits the second bolt 42 (the spring 421 generates a pulling force on the second bolt 42, i.e., the dynamic wear-resistant plate 22), thereby limiting the bottom movement position of the dynamic wear-resistant plate 22, thereby preventing the bottom of the dynamic wear-resistant plate 22 from moving irregularly, making the size of the discharge port 25 uncertain, and thus failing to intercept frozen food waste with a larger diameter.

[0031] As an implementable embodiment, a plurality of raised teeth 5 are provided on the end surface of the fixed wear-resistant plate 21 close to the dynamic wear-resistant plate 22 and the end surface of the dynamic wear-resistant plate 22 close to the fixed wear-resistant plate 21. Among them, the plurality of raised teeth 5 on the fixed wear-resistant plate 21 and the plurality of raised teeth 5 on the dynamic wear-resistant plate 22 are arranged along the vertical direction of the crushing zone 24. The fixed wear-resistant plate 21 and the dynamic wear-resistant plate 22 are made of ZGMn13-4 material and quenched as a whole, and have better strength and wear resistance. The provision of the raised teeth 5 is conducive to increasing local pressure, so that the frozen food waste is unevenly stressed, making it easier to crush. At the same time, the plurality of raised teeth 5 are arranged in the vertical direction of the crushing zone 24, which is more conducive to the falling of materials.

[0032] As an implementation method, a receiving bucket is further included inside the frame 1, and a receiving port of the receiving bucket is located below the discharge port 25. Frozen kitchen waste with a diameter less than 100 mm enters the receiving bucket through the discharge port 25, and the receiving bucket temporarily collects the waste and waits for subsequent equipment (subsequent conveyor and pulping equipment) to process it.

[0033] The embodiments described above are only preferred embodiments of the present invention and are only used to explain the present invention, not to limit the scope of implementation of the present invention. For those skilled in the art, other implementation methods can certainly be easily made by replacement or modification based on the technical contents disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of the present invention should be included in the scope of the patent application of the present invention.
