Description

Technical Field

[0001] The invention relates to the technical field of dirt cleaning, in particular to a meat and bone meal crushing system with a cleaning function. Background Art

[0002] ‌Meat and bone meal crushers need to be cleaned regularly. The main purpose of cleaning is to ensure food hygiene, extend the service life of the equipment and prevent equipment failure. ‌During the use of the meat and bone meal crusher, debris, grease and other substances will remain inside the equipment. If not cleaned, these residues will contaminate the material during the next use, causing food deterioration and contamination, thus affecting the quality and safety of the food‌.

[0003] The prior art provides a cleaning function for the meat and bone meal crushing system by directly installing a rotating washing mechanism inside the crusher, so that when cleaning is performed subsequently, the washing mechanism is directly started to clean the inner wall. However, this solution will occupy a certain cleaning area, resulting in the coverage of the crushing blade being blocked by the cleaning mechanism and causing a processing dead angle, which will reduce the efficiency of the meat and bone meal crushing. On the other hand, during cleaning, a large amount of material will adhere to the inner wall and the blade, so that the conventional cleaning function cannot fully cover the inner wall and the blade surface, and it is difficult to fully remove the stubborn stains that adhere. It is also easy to cause the spray hole to be blocked during the crushing and stirring process by flushing. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] See also Figures 1 to 7The present invention provides the following technical solutions: A meat and bone meal crushing system with a cleaning function, comprising a crushing box 1, a front-end driving mechanism 4, a rear-end driving mechanism 5 and a scraping assembly 6, wherein the side of the crushing box 1 is screwed with a side plate 31, and a cover plate 2 is installed at one end of the surface of the crushing box 1, and a drainage plug 33 is provided at the other end of the surface of the crushing box 1, a flushing pipe 3 is inserted in the middle of the side of the crushing box 1, the front-end driving mechanism 4 is embedded into the interior from the front-end side plate 31 of the crushing box 1, and a crushing guide roller is inserted in the middle of the front-end driving mechanism 4 29, the number of the crushing guide rollers 29 is two, the interior of the crushing box 1 is divided into a stockpile cavity 7 and a crushing cavity 8, and the crushing guide rollers 29 all pass through the interior of the crushing cavity 8, the stockpile cavity 7 is symmetrically opened on both sides of the crushing cavity 8, and a scraping assembly 6 is installed inside each of the stockpile cavities 7, and the side of the scraping assembly 6 fits the inner wall of the crushing box 1, the rear end drive mechanism 5 is inserted on the rear end side plate 31 of the crushing box 1, and the end of the front end drive mechanism 4 is inserted into the interior of the rear end drive mechanism 5. The meat and bone meal crushing system with cleaning function is used in the production and processing of meat and bone meal, and can provide a cleaning effect on the inner wall during the crushing process and after use.

[0021] When the present invention is used, the raw material to be crushed is put into the interior of the crushing box 1 from the cover plate 2 area on the side of the crushing box 1, and when putting it in, the cover plate 2 area needs to be rotated downward to avoid being blocked by the scraper assembly 6, and then the cover plate 2 can be closed and locked and sealed, and then the front-end driving mechanism 4 and the rear-end driving mechanism 5 are started, and the front-end driving mechanism 4 controls the rotation of the crushing guide roller 29, and the rear-end driving mechanism 5 periodically controls the entire crushing box 1 to rotate intermittently. Each time the crushing box 1 is controlled to rotate 180 degrees, the raw material that has fallen on the bottom scraper assembly 6 will be pushed to the top and fall toward the bottom. When falling, it passes through the middle position of the crushing guide roller 29, and can be crushed by the crushing guide roller 29 in the crushing cavity 8 area, and fall into the stockpile cavity 7 rotated to the bottom, and the above process is repeated until it is completely crushed. In this process, the scraping assembly 6 is also used to repeatedly scrape off the raw materials adhering to the stockpile cavity 7 and the outer arc plate 18, ensuring that all the raw materials can repeatedly pass through the inside of the crushing cavity 8. When the crushing process is completed, the crushing box 1 is controlled to rotate to a horizontal state, and in this state, a high-pressure water flow is injected from the external water injection port 19. With the help of this water flow, the crushing guide roller 29 is flushed in cooperation with the front-end driving mechanism 4 in the rotating state, and at the same time, the scraping assembly 6 is also shaken up and down to realize the cleaning process of the inner wall.

[0022] In this embodiment, an inner convex plate 9 is integrally formed on the inner wall of the crushing box 1, an outer arc plate 18 is arranged on the outer side of the inner convex plate 9, an inner arc plate 34 is arranged on the inner wall of the inner convex plate 9, the cross section of the inner arc plate 34 is a circular structure, and the side of the front end driving mechanism 4 is in contact with the surface of the inner arc plate 34. A water injection port 19 is provided at one end of the flushing pipe 3, and a plurality of spray holes 30 are provided on the side of the flushing pipe 3, and the spray holes 30 are connected to the inner wall of the crushing cavity 8. The flushing pipe 3 and the spray holes 30 are symmetrically arranged on both sides of the crushing box 1, and the spray holes 30 are used to flush and clean the crushing guide roller 29. During cleaning, the inner convex plate 9 structure in the center can also be used to specifically clean the crushing guide roller 29 and the inner wall of the crushing box 1, thereby improving the cleaning effect. As for the crushing cavity 8 area in the center, after the crushing box 1 is controlled to be in a horizontal state, the injected high-pressure water flow can be directly used to flush the crushing guide roller 29 area. At this time, in conjunction with the normal operation of the front-end driving mechanism 4, the crushing guide roller 29 and the inner wall of the enclosure 26 can be fully cleaned, thereby improving the cleaning performance. At the same time, the enclosure 26 can also be used to partially block the spray hole 30 during operation, thereby preventing the problem of the variable spray hole 30 being blocked by materials.

[0023] Specifically, during cleaning, water is directly injected from the water inlet 19 into the inside of the flushing pipe 3, and then partially flushed into the crushing cavity 8 from the spray hole 30 on the side of the flushing pipe 3. Since the crushing box 1 is in a horizontal position as a whole at this time, the flushed water flow can directly flush into the surface of the crushing guide roller 29 from the feed notch 28, and cooperate with the rotation effect of the crushing guide roller 29 to achieve the targeted cleaning purpose, and also clean the inner wall of the enclosure 26. During use, since the crushing box 1 can only be rotated to a vertical or nearly vertical state, the raw materials accumulated on the top can pass through the feed notch 28 at the bottom and fall downward. At this angle, the spray holes 30 on both sides of the crushing box 1 are always closed and blocked by the outer side of the enclosure 26. Therefore, during normal operation, it is possible to prevent the raw materials from partially clogging the spray holes 30.

[0024] In this embodiment, the scraper assembly 6 includes a lifting plate 12, a scraper 14 and a guide rod 16. A rotating shaft 13 is inserted into the side of the lifting plate 12. The scraper 14 is connected to the surface of the rotating shaft 13. A first spring 11 is connected to the inner wall of the scraper 14. The other end of the first spring 11 is welded to the surface of the lifting plate 12. One end of the guide rod 16 is welded to the surface of the lifting plate 12. Guide holes 32 are provided at both ends of the crushing box 1. The guide rod 16 passes through the inside of the guide hole 32, and the end of each guide rod 16 is screwed with a limiting convex ring 17. A sealing ring is attached to the inner wall of the guide hole 32. The scraper 14 is pressed against the inner wall of the stacking cavity 7 or the surface of the outer arc plate 18 by the first spring 11. The scraping assembly 6 automatically lifts and lowers during the crushing process to assist the material to repeatedly pass through the middle of the crushing guide roller 29. At the same time, the second spring 15 and the scraper 14 on the scraping assembly 6 can further push the material accumulated in the outer arc plate 18 area on the inner convex plate 9 toward the middle, further expanding the scraping coverage area and assisting the material to concentrate toward the crushing guide roller 29 area.

[0025] Specifically, when the crushing box 1 rotates to the top, the upper scraper assembly 6 moves downward. Since the second spring 15 always pushes the scraper 14 partly toward the side, the scraper 14 can always press on the inner wall of the stockpiling cavity 7, and in the subsequent downward movement of the scraper assembly 6, the raw materials adhered to the inner wall of the stockpiling cavity 7 are pushed toward the bottom with the help of the scraper 14. Finally, after the scraper 14 moves to the top of the outer arc plate 18, the scraper 14 will be moved downward along the outer arc plate 18 by the lifting plate 12 and the scraper 14's own gravity, so that the edge of the scraper 14 can still move downward along the outer arc plate 18, and finally the raw materials adhered to the outer arc plate 18 are also pushed toward the middle material discharge notch 28 position, and the scraper assembly 6 at the bottom falls toward the bottom, and each scraper assembly 6 realizes a stable lifting and lowering movement process through the guide rod 16.

[0026] In this embodiment, the front-end driving mechanism 4 includes a first motor 20 and a crushing guide roller 29, the output end of the first motor 20 is inserted with a first driving shaft 21, the surface of the front end side plate 31 of the crushing box 1 is welded with a transmission box 25, the interior of the transmission box 25 is equipped with a driving gear 22 and a driven gear 23, and the end of the crushing guide roller 29 is sleeved with an end plate 27. The first driving shaft 21 passes through the interior of the transmission box 25, the driving gear 22 is keyed to the surface of the first driving shaft 21, and the driving gear 22 and the driven gear 23 are meshed, the middle key of the driven gear 23 is connected with the driven shaft 24, and the crushing guide roller 29 is respectively fixed on the surface of the first driving shaft 21 and the driven shaft 24. A shroud 26 is welded between the end plate 27 and the transmission box 25. The shroud 26 is an arc-shaped structure as a whole, and a material cutting notch 28 is opened on the side of the shroud 26. The outer side of the shroud 26 fits the inner wall of the inner arc plate 34, and the width of the material cutting notch 28 is the same as the spacing between the bottoms of two adjacent outer arc plates 18. The rear end driving mechanism 5 includes a second motor 38 and a second drive shaft 36. The bottom of the housing of the first motor 20 and the second motor 38 are both screwed with a support frame 37, and the output end of the second motor 38 is inserted with the second drive shaft 36. A docking sleeve 35 is integrally formed on the side plate 31 at the rear end of the crushing box 1, and the end of the second drive shaft 36 is screwed on the outer side of the docking sleeve 35. The end plate 27 is embedded in the interior of the docking sleeve 35, and the side of the end plate 27 is rotatably connected to the inner wall of the docking sleeve 35 through a ball bearing. The second motor 38 controls the crushing box 1 to perform intermittent rotation. The driving mechanisms at the front and rear ends are used to control the internal raw materials to repeatedly pass through the middle position of the two crushing guide rollers 29 to achieve the purpose of crushing, and the crushing is more complete. The scraping components 6 at both ends can repeatedly scrape off the raw materials adhering to the inner wall during the crushing process, so that the raw materials can be fully crushed and dead corners can be avoided.

[0027] Specifically, after starting the first motor 20, the first drive shaft 21 and the driving gear 22 are driven to rotate, and then the driven gear 23 and the driven shaft 24 are cooperated to drive the crushing guide roller 29 to rotate, so that the raw materials falling from the top can be crushed, and the transmission box 25 and the end plate 27 at the rear end are always kept fixed. When the crushing box 1 is partially turned upside down, the transmission box 25 and the end plate 27 at the rear end are also always kept stable. In the rear end driving mechanism 5, the second drive shaft 36 is directly driven to rotate by the second motor 38, and the docking sleeve 35 can be cooperated to realize the periodic rotation control process of the crushing box 1.
