Description

Technical Field

[0001] The invention belongs to the technical field of edible vinegar processing, in particular to a wheat crushing device. Background Art

[0002] Vinegar is a liquid material that is often used in daily life. It is divided into edible vinegar and industrial vinegar. Edible vinegar is used as a seasoning in daily cooking. A variety of raw materials are needed in the production and processing of edible vinegar, including wheat. The wheat needs to be crushed before use. After crushing, the wheat will be easier to ferment and the vinegar production efficiency will be higher.

[0003] A patent application with publication number CN115870046A discloses a wheat grinding device for wheat flour production. The present invention provides a wheat grinding device for wheat flour production that facilitates unloading. The device comprises a support frame, a fixed frame, a motor, grinding rollers, and a first spur gear. Wheat is placed in the loading frame and continuously falls onto two grinding rollers for grinding.

[0004] When the above-mentioned technical solution is used, the wheat needs to be crushed by rotating the crushing roller, and the wheat flour is brushed off from the surface of the crushing roller by a brush after crushing. However, the crushing roller will exert a large pressure on the wheat during the crushing process, causing the starch inside the wheat to stick tightly to the surface and groove of the crushing roller. Therefore, some of the starch will be missed when the brush cleans the crushing roller. The missed starch will remain on the surface of the crushing roller for a long time and is prone to deterioration, thereby affecting the quality of the subsequently crushed wheat.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] like Figures 1 to 5 As shown, a wheat crushing device described in an embodiment of the present invention includes a shell 1, a discharge hopper 11 is fixed to the top of the shell 1, a discharge port 12 is opened at one end of the shell 1, a guide plate is fixed to the position of the shell 1 near the discharge port 12, and grinding rollers 2 are rotatably connected on both sides of the shell 1. The end of the grinding roller 2 away from the discharge port 12 is fixed with a first gear 22, and a scraper plate 21 is provided on one side of the first gear 22. The scraper plate 21 is fixedly connected to the shell 1, and a motor 13 is provided below the first gear 22. The motor 13 is installed at the end of the shell 1 away from the discharge port 12, and one of the first gears 22 is provided with teeth at the end away from the shell 1. An output gear is fixed to the end of the rotating shaft of the motor 13, and the output gear is meshed with the teeth at one end of the first gear 22. A water tank 3 is fixed to the top of the shell 1 near the motor 13, and a water pump 31 is installed on the top of the water tank 3. A water spray head 33 is provided inside the shell 1, and a water pipe 32 is fixed between the water spray head 33 and the water pump 31;

[0034] When making edible vinegar, wheat needs to be crushed. The wheat to be crushed is first washed with clean water and then dried. The dried wheat is put into the discharge hopper 11. At this time, the wheat falls into the interior of the housing 1 through the discharge hopper 11. At the same time, the motor 13 is started to drive the first gear 22 to rotate. The two first gears 22 rotate towards each other. The first gear 22 drives the grinding roller 2 inside the housing 1 to rotate. The surface of the grinding roller 2 has a plurality of equally spaced hemispherical protrusions. The protrusions can grind the wheat. The crushed wheat will fall to the guide plate inside the housing 1. The guide plate can discharge the crushed wheat to the outside through the discharge port 12. At this time, a container can be used to collect the crushed wheat.

[0035] When the milling roller 2 grinds the wheat, since wheat contains about 70% starch, a large amount of starch will be squeezed out and tightly adhere to the surface of the milling roller 2 under the pressure of the bumps. At this time, the scraper 21 on one side of the milling roller 2 can scrape off the starch on the surface of the milling roller 2 and the wheat debris that has not fallen off the surface of the milling roller 2. The scraped starch and debris can be discharged from the discharge port 12 under the guidance of the guide plate. The scraping groove of the scraper 21 is provided with a plastic strip, which can automatically deform according to the shape of the bumps on the surface of the milling roller 2 and scrape off the starch and debris.

[0036] When the scraper plate 21 is scraping the material on the surface of the grinding roller 2, there are still some dead corners that cannot be scraped off. The starch in the dead corners will accumulate for a long time and be affected by the moisture in the outside air, which will cause it to deteriorate. Therefore, the outside of the grinding roller 2 needs to be cleaned after use. At this time, the water pump 31 is started to extract the water inside the water tank 3, and then the water pump 31 inputs the water into the inside of the water head 33 through the water pipe 32. The water head 33 sprays the water onto the surface of the grinding roller 2. At this time, the starch on the surface of the grinding roller 2 can be flushed down by the water flow, and the flushed water can be discharged to the outside of the shell 1 through the guide plate.

[0037] like Figures 1 to 6 As shown, a feed pipe 111 is fixed to the bottom end of the discharge hopper 11, and a discharge port 112 is fixed to the bottom end of the feed pipe 111. Slide sleeves 42 are fixed to both sides of the discharge port 112 through support plates. A bidirectional screw rod 4 is provided on both sides of the discharge port 112. The bidirectional screw rod 4 is rotatably connected to the interior of the housing 1. The slide sleeve 42 is threadedly connected to the bidirectional screw rod 4. A second gear 41 is fixed to the end of the bidirectional screw rod 4 close to the motor 13. The second gear 41 is meshed with the first gear 22. A water spray head 33 is provided on one side of the discharge port 112.

[0038] When the discharge hopper 11 discharges the material above the grinding roller 2, it will be discharged to the same position. At this time, more areas of the grinding roller 2 will be unused, and a large amount of wheat will be accumulated in the area where the grinding roller 2 is located at the discharge port of the discharge hopper 11, resulting in low grinding efficiency. Therefore, when the first gear 22 rotates, it will also drive the second gear 41 to rotate, and the second gear 41 will drive the bidirectional screw rod 4 to rotate. After the bidirectional screw rod 4 rotates, it will drive the sleeve 42 to reciprocate outside the bidirectional screw rod 4. At this time, the sleeve 42 drives the discharge port 112 to rotate in the grinding The top of the material roller 2 reciprocates, and the discharge hopper 11 inputs wheat into the inside of the discharge port 112 through the feed pipe 111. The discharge port 112 sprays out the wheat at the same time during the reciprocating movement. At this time, the wheat can be evenly output to the grinding area of the grinding roller 2. The surface of the bidirectional screw rod 4 is provided with two sets of guide grooves in different directions. The inside of the sliding sleeve 42 slides inside the guide groove through the protrusion. When the sliding sleeve 42 slides to one end of the bidirectional screw rod, it will be guided by the current guide groove to switch to the groove in the other direction, thereby completing the reversal of the sliding sleeve 42.

[0039] After the wheat milling is completed, the milling roller 2 needs to be cleaned. At this time, all the wheat inside the hopper 11 is discharged, and then the motor 13 is started to drive the milling roller 2 to continue rotating. At the same time, the water pump 31 is started to supply water to the water spray head 33. At this time, the bidirectional screw 4 drives the discharge port 112 to move while driving the water spray head 33 to move. The water spray head 33 sprays water to rinse the surface of the milling roller 2. The movement of the water spray head 33 during the rinsing process allows the water spray head 33 to rinse more areas of the milling roller 2, so that the surface of the milling roller 2 can be rinsed more cleanly.

[0040] like Figures 1 to 9 As shown, a water nozzle 36 is fixed to the bottom end of the water spray head 33, and a guide plate 346 is rotatably connected to the bottom end of the water spray nozzle 36;

[0041] When the water spray head 33 sprays water, the water spray head 33 sprays water to the outside through the water spray nozzle 36. At this time, the water spray nozzle 36 can make the water spray range larger. At the same time, the guide plate 346 can rotate left and right. When the guide plate 346 rotates left and right, the water flow can be blocked. The blocked water flow changes the spraying direction, so that the sprayed water flow can cover a wider area of the surface of the grinding roller 2 and have a better cleaning effect.

[0042] like Figures 1 to 10 As shown, the side of the water spray head 33 away from the discharge port 112 is rotatably connected to a steering wheel 343, and the end of the steering wheel 343 away from the water spray head 33 is fixed with a first pulley 344 through a rotating shaft. The end of the guide plate 346 rotating shaft close to the first pulley 344 is fixed with a second pulley 345, and the first pulley 344 and the second pulley 345 are connected by a belt;

[0043] When the guide plate 346 needs to rotate left and right, the steering wheel 343 drives the first pulley 344 to rotate, and the first pulley 344 drives the second pulley 345 to rotate through the belt. The second pulley 345 can drive the guide plate 346 to rotate left and right, so that the steering wheel 343 will not block the guide plate 346 during rotation.

[0044] like Figures 1 to 10 As shown, the internal rotation of the water sprinkler head 33 is connected to a runner 34, and a transmission disc 341 is fixed to the end of the rotating shaft of the runner 34 away from the water sprinkler head 33. The end of the transmission disc 341 away from the runner 34 is rotationally connected to a connecting arm 342, and the other end of the connecting arm 342 is rotationally connected to a steering wheel 343;

[0045] When water flows through the sprinkler head 33, it drives the runner 34 to rotate. At this time, the runner 34 drives the transmission disc 341 to rotate, and the transmission disc 341 drives the steering disc 343 to rotate through the connecting arm 342. When the transmission disc 341 rotates one circle, the transmission disc 341 drives the steering disc 343 to swing left and right once through the connecting arm 342, which can automatically drive the guide plate 346 to rotate left and right.

[0046] like Figures 1 to 8 As shown, the outer side of the discharge port 112 is slidably connected to the first push rack 331 through a connecting sleeve, and the two push rods of the first push rack 331 are externally sleeved with a spring 332, one end of the spring 332 is fixedly connected to the connecting sleeve of the discharge port 112, and the other end of the spring 332 is fixedly connected to the first push rack 331, and the end of the spring 332 away from the discharge port 112 is rotatably connected to the water spray head 33, and the water spray head 33 is rotatably connected to the discharge port 112 through the connecting rack;

[0047] The water spray head 33 is arranged on one side of the discharge port 112, so there will be a certain dead angle when the water spray head 33 flushes the surface of the grinding roller 2. In order to solve this problem, a first push frame 331 is provided. When the discharge port 112 drives the water spray head 33 to move to the inner wall position of the shell 1 away from the side of the water spray head 33, the first push frame 331 will contact the inner wall of the shell 1. At the same time, the discharge port 112 will drive the water spray head 33 and the first push frame 331 to move continuously. The shell 1 applies a thrust to the first push frame 331, and the first push frame 331 pushes the top of the water spray head 33 The water spray head 33 rotates on one side of the discharge port 112. At this time, the water spray head 33 will drive the water spray nozzle 36 to rotate toward the discharge port 112. During the rotation, the water spray nozzle 36 continues to spray water. The water spray nozzle 36 can rinse the grinding roller 2 more comprehensively. When the discharge port 112 moves close to the shell 1, it will move in the opposite direction. At this time, the first push frame 331 will automatically reset under the action of the spring 332. The first push frame 331 also drives the water spray head 33 to reset. At this time, the water spray head 33 completes one rinse. In this way, the surface of the grinding roller 2 can be repeatedly rinsed back and forth.

[0048] like Figures 1 to 6 As shown, a baffle plate 43 is provided on both sides of the bottom end of the discharge port 112, and a rotating rod 431 is fixed to one side of the baffle plate 43, and the rotating rod 431 is rotatably connected to the discharge port 112;

[0049] The two baffles 43 can block the bottom end of the discharge port 112. When the grinding roller 2 needs to be cleaned, the discharge port 112 stops discharging, but some wheat may not be discharged from the discharge hopper 11. At this time, the baffles 43 can block the wheat inside the discharge port 112, preventing the wheat from being discharged during the cleaning process of the water spray head 33 and causing waste of wheat.

[0050] like Figures 1 to 6 As shown, an electric telescopic rod 44 is installed at the end of the discharge port 112 away from the water spray head 33, and a second push frame 441 is fixed to the bottom end of the electric telescopic rod 44. Guide sliding holes 442 are opened on both sides of the interior of the second push frame 441. Connecting strips 432 are fixed to both ends of the rotating rod 431. A sliding column is fixed to the end of the connecting strip 432 away from the rotating rod 431. The sliding column is slidably connected to the interior of the guide sliding hole 442;

[0051] When the baffle plate 43 needs to be rotated, the electric telescopic rod 44 is started to push the second pushing frame 441, and the second pushing frame 441 drives the connecting bar 432 to rotate through the guide slide hole 442. During the rotation of the connecting bar 432, the rotating rod 431 is driven to rotate. At this time, the rotating rod 431 can drive the baffle plate 43 to rotate. The electric telescopic rod 44 drives the second pushing frame 441 to rise and fall to control the switch of the baffle plate 43, which is more convenient to control the on and off of the discharge of the material from the discharge port 112.

[0052] like Figures 1 to 9 As shown, a lifting cylinder 351 is provided inside the water spray head 33, and a sealing plug 352 is fixed to the bottom end of the water spray head 33. The sealing plug 352 can be inserted into the lifting cylinder 351;

[0053] In the initial state, the sealing plug 352 is inserted into the interior of the lifting cylinder 351. At this time, the interior of the lifting cylinder 351 can be blocked, so that water inside the sprinkler head 33 cannot flow. When water needs to be transported to the inside of the water nozzle 36 from the inside of the sprinkler head 33, the lifting cylinder 351 moves upward. At this time, the sealing plug 352 is separated from the inside of the lifting cylinder 351, and water can flow inside the lifting cylinder 351, which can make it easier to control the on and off of the water flow inside the sprinkler head 33.

[0054] like Figures 1 to 9As shown, the lifting cylinder 351 is rotatably connected to the movable arm 35 through a connecting block on the side near the discharge port 112. Guide sliding holes 442 are also provided on both sides of the interior of the movable arm 35. The sliding column of the connecting bar 432 at one end of the movable arm 35 is also slidably connected to the interior of the guide sliding hole 442. A bending structure is provided at the connection between the connecting bar 432 at one end of the movable arm 35 and the rotating rod 431. A sliding hole for sliding the connecting block of the lifting cylinder 351 is provided on the outer side of the sprinkler head 33.

[0055] When the baffle plate 43 rotates to block the bottom end of the discharge port 112, the movable arm 35 will be driven upward by the rotating rod 431 at the same time. At this time, the movable arm 35 drives the lifting cylinder 351 to move upward, so that the lifting cylinder 351 can be connected with the water spray head 33. When the baffle plate 43 is opened, the movable arm 35 drives the lifting cylinder 351 to move downward, and the sealing plug 352 seals the lifting cylinder 351, so that the connection between the lifting cylinder 351 and the water spray head 33 can be controlled while the baffle plate 43 opens and closes the discharge port 112. The bending structure at the connection between the connecting strip 432 at one end of the movable arm 35 and the rotating rod 431 enables the movable arm 35 to move when the first push frame 331 drives the water spray head 33 to rotate.
