[0002] The beef deep processing industry is an important part of China's food industry. With the improvement of living standards and the growth of market demand, the refinement and safety and hygiene requirements of beef products are increasingly improved. Under this background, the beef crushing equipment for making meat paste and other products is widely used in the industry. The existing beef crushing equipment is mainly a chopping mixer, and the technical level is directly related to the quality and production efficiency of the product.

[0003] The existing beef crushing device, especially using vacuum technology in the chopping process, is prone to meat attachment on the inner wall of the chopping pot, the pot cover, the chopping knife and other parts, and even leakage from the gap between the parts. Not only does it cause material loss, but it also poses a health risk. In addition, the structural design of the traditional equipment often has cleaning dead angles, especially the connection between the chopping knife mechanism and the chopping pot cover and other complex components is difficult to clean thoroughly, and the residual meat paste is prone to spoilage, which poses a threat to the food safety of subsequent products.

[0004] Invention patent CN202410615318.4 discloses a new chopping mixer, and specifically discloses that it comprises a base, a chopping pot, a chopping pot cover assembly, a swinging arm assembly, a diagonal fork arm assembly and a chopping knife assembly.

[0022] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0023] Please refer to Figures 1 to 7 As shown in the drawings, a beef deep processing beef crushing device, comprising: a base 1 for separating the chopping pot assembly 22 and the chopping pot cover 23 and the chopping knife mechanism 3 and the chopping pot cover 23, a chopping pot mechanism 2 for moving the meat, and a chopping knife mechanism 3 for chopping the meat.

[0024] The base 1 comprises a turnover assembly 11 and a lifting assembly 12, and the lifting assembly 12 is installed on the turnover assembly 11.

[0025] Specifically, the turnover assembly 11 is provided with a turnover beam 111, and the turnover beam 111 is fixedly connected with the outer cover 231. That is, the turnover assembly 11 can drive the turnover beam 111 and the chopping pot cover 23 to turn together, thereby realizing the combination and separation of the chopping pot cover 23 and the chopping pot assembly 22.

[0026] The lifting assembly 12 comprises a sliding rail 121, a lead screw 122, a first motor 123 and a lifting beam 124. The sliding rail 121 is fixedly arranged on the turnover beam 111, the lead screw 122 is rotatably arranged on the sliding rail 121, the lead screw 122 is connected with the first motor 123, and the lifting beam 124 is threadedly connected with the lead screw 122.

[0027] The lifting beam 124 is slidably arranged in the sliding rail 121, and the lifting beam 124 is fixedly connected with the cutter seat 31. That is, the first motor 123 can drive the lifting beam 124 and the cutter mechanism 3 to slide up and down along the sliding rail 121 through the lead screw 122, so as to realize the connection and separation of the cutter mechanism 3 and the pot cutting mechanism 2.

[0028] The pot cutting mechanism 2 comprises an outer shell 21, a pot cutting assembly 22 and a pot cutting cover 23. The outer shell 21 is fixed on the base 1.

[0029] The pot cutting assembly 22 comprises a pot cutter 221, a guide rod 222 and a second motor 223. The pot cutter 221 is rotatably arranged in the outer shell 21, the guide rod 222 is arranged on the pot cutter 221, and the bottom of the pot cutter 221 is connected with the second motor 223. It can be understood that the second motor 223 can drive the pot cutter 221 to rotate in the outer shell 21, and at the same time, the meat on the pot cutter 221 is rotated together, and the meat moves to the cutter head 36 of the cutter mechanism 3 for cutting.

[0030] The pot cutting cover 23 comprises an outer cover 231, an inner cover 233, a feeding pipe 235 and a cutter groove 236. The outer cover 231 is fixed on the turnover assembly 11, and the inner cover 233 is fixed in the outer cover 231. It should be noted that in the embodiment, the lower end of the outer cover 231 is not connected with the lower end of the inner cover 233, and there is a gap, and preferably the gap corresponds to the gap between the outer shell 21 and the pot cutter 221.

[0031] Specifically, the outer cover 231 is provided with an air pipe 232. The air pipe 232 is connected with the vacuumizing equipment in the factory building.

[0032] The lower end of the inner cover 233 is slidably connected with the upper end of the pot cutter 221, and the lower end of the outer cover 231 is connected with the upper end of the outer shell 21.

[0033] Specifically, the inner cover 233 is provided with a first air hole 234. It should be noted that in the embodiment, a vacuum cavity is arranged between the outer cover 231 and the inner cover 233, a cutting cavity is arranged between the inner cover 233 and the pot cutter 221, and the first air hole 234 communicates the vacuum cavity and the cutting cavity. It can be understood that the vacuumizing equipment can simultaneously perform vacuumizing on the air pipe 232 and the first air hole 234, and on the vacuum cavity and the cutting cavity.

[0034] Specifically, the lower end of the cutter seat 31 is provided with a connecting sleeve 311, and the connecting sleeve 311 is provided with a second air hole 312. The cutter mechanism 3 further comprises a connecting pipe 35, the connecting sleeve 311 is connected with the swing cutter arm 33 through the connecting pipe 35, and the connecting pipe 35 wraps the connecting part of the fixed cutter arm 32 and the swing cutter arm 33 and the exposed part of the transmission assembly. It can be understood that the second air hole 312 communicates the inside of the connecting pipe 35 with the chopping cavity, and when the chopping cavity is subjected to vacuumizing treatment, the inside of the connecting pipe 35 can be subjected to synchronous vacuumizing treatment through the second air hole 312, so as to prevent the inside and outside of the connecting pipe 35 from having a large air pressure difference, so that the connecting pipe 35 is expanded to affect the movement of the meat material, and even causes the connecting pipe 35 to be broken.

[0035] The feeding pipe 235 and the cutter groove 236 are connected with the outer cover 231 and the inner cover 233.

[0036] The cutter mechanism 3 comprises a cutter seat 31, a fixed cutter arm 32, a swing cutter arm 33, a cutter head 36 and a third motor 37. The upper end of the fixed cutter arm 32 is fixedly connected to the cutter seat 31, the swing cutter arm 33 is hinged to the lower end of the fixed cutter arm 32, the cutter head 36 is installed at the lower end of the swing cutter arm 33, and the cutter head 36 is connected with the third motor 37 through a transmission assembly. Specifically, the cutter seat 31 cooperates with the cutter groove 236.

[0037] Specifically, the transmission assembly comprises a first rotating shaft 321, a second rotating shaft 333 and a universal joint 34. The first rotating shaft 321 is rotationally arranged on the fixed cutter arm 32, the second rotating shaft 333 is rotationally arranged on the swing cutter arm 33, one end of the first rotating shaft 321 is connected with the third motor 37, the other end is connected with the second rotating shaft 333 through the universal joint 34, and the second rotating shaft 333 cooperates with the cutter head 36 through a gear.

[0038] The swing cutter arm 33 is further provided with an inclined surface 331 and a sliding groove 332. The inclined surface 331 is arranged on one side of the lower end of the swing cutter arm 33, and the sliding groove 332 is arranged on the side wall of the swing cutter arm 33 close to the inclined surface 331. The inclined surface 331 and the sliding groove 332 are in sliding cooperation with the guide rod 222. It can be understood that during the process that the lifting assembly 12 drives the cutter mechanism 3 to enter the chopping cavity from the cutter groove 236, the inclined surface 331 contacts the upper end of the guide rod 222 first, and guides the swing cutter arm 33 to swing, until the guide rod 222 slides into the sliding groove 332. With the descending of the cutter mechanism 3, the swing cutter arm 33 is flipped to the side of the chopping pot 221 under the guidance of the guide rod 222. When the cutter seat 31 cooperates with the cutter groove 236, the cutter head 36 cooperates with the chopping pot cover 23.

[0039] Specifically, the swing knife arm 33 is further provided with a limiting block 334, the limiting block 334 is fixedly arranged on the side of the swing knife arm 33 away from the sliding groove 332, the limiting block 334 cooperates with the fixed knife arm 32 to limit the swing angle of the swing knife arm 33. It should be noted that when the cutter head 36 is just matched with the chopping pot cover 23, the limiting block 334 is just matched with the fixed knife arm 32 to limit the swing of the swing knife arm 33, so that the force generated during chopping of the meat does not cause the cutter head 36 to separate from the chopping pot 221, and the chopping effect is affected.

[0040] The working principle of the present application is as follows: Before operation: the turnover assembly 11 drives the turnover beam 111 and the chopping pot cover 23 to turn down together until the chopping pot cover 23 is combined with the chopping pot assembly 22. The first motor 123 can drive the lifting beam 124 and the chopping knife mechanism 3 to slide down along the sliding rail 121 through the screw rod 122, so that the lower end of the chopping knife mechanism 3 enters the chopping cavity from the knife groove 236 until the chopping knife mechanism 3 is connected with the chopping pot mechanism 2.

[0041] During the process that the chopping knife mechanism 3 is connected with the chopping pot mechanism 2, the inclined surface 331 contacts the upper end of the guide rod 222 first and guides the swing of the swing knife arm 33 until the guide rod 222 slides into the sliding groove 332. With the descending of the chopping knife mechanism 3, the swing knife arm 33 turns over to the side of the chopping pot 221 under the guidance of the guide rod 222. When the knife seat 31 cooperates with the knife groove 236, the cutter head 36 is just matched with the chopping pot cover 23, and the limiting block 334 is just matched with the fixed knife arm 32 to limit the swing of the swing knife arm 33.

[0042] During operation: artificial or conveying equipment adds meat to the chopping cavity through the feeding pipe 235, and the second motor 223 can drive the chopping pot 221 to rotate in the shell 21, and the meat on the chopping pot 221 is rotated together, so that the meat moves to the cutter head 36 of the chopping knife mechanism 3 for chopping, and the chopping knife mechanism 3 grinds the meat into meat paste, and the adhesion of the meat can be effectively reduced due to the action of the connecting pipe 35. Then the meat paste on the chopping pot 221 is taken out of the equipment by artificial or equipment.

[0043] After operation: the turnover assembly 11 drives the turnover beam 111 and the chopping pot cover 23 to turn up together until the chopping pot cover 23 is separated from the chopping pot assembly 22. The first motor 123 can drive the lifting beam 124 and the chopping knife mechanism 3 to slide up along the sliding rail 121 through the screw rod 122, so that the chopping knife mechanism 3 is at least partially lifted from the sliding groove 332, and preferably, the chopping knife mechanism 3 is completely lifted from the sliding groove 332, at this time, the chopping knife mechanism 3 is separated from the chopping pot mechanism 2. Then the whole equipment is cleaned by artificial or cleaning equipment, which effectively reduces the residue of the meat at the connection between the chopping knife mechanism and the chopping pot cover and other complex components.
