When the grain raw materials above the screen are accumulated, the smaller grain raw materials that fall on the top will slide to the side along with the larger grain raw materials. The smaller grain raw materials will not be crushed when passing through the crushing roller, which prolongs the crushing time and reduces the practicability of the device. Summary of the invention

[0007] Preferably, an external motor is installed on the front side of the crushing box, a gear is installed on the end of the shaft of the crushing roller, the gear is located outside the crushing box, the output end of the external motor is fixedly connected to one side gear shaft, and the gears on the left and right sides are meshed with each other.

[0008] Preferably, a feeding port is provided at the bottom of the crushing box, and a limit plate is installed on the inner side of the crushing box. The inner wall of the limit plate fits the end of the filter plate, the curvature of the inner wall of the limit plate is the same as the curvature formed by the rotation of the filter plate, and the ends of the filter plates away from the limit plate are in contact with each other.

[0010] Preferably, the attraction force of the lower magnets on the left and right sides is smaller than the weight of the counterweight.

[0011] Preferably, a transverse limiting rod and a mounting rod are installed at the top of the crushing box. The mounting rod is located at the top of the limiting rod. The rope passes around the top of the limiting rod. Plugs are passed through both ends of the mounting rod. A pull rope is arranged between the end of the plug away from the crushing box and the bottom of the counterweight block.

[0012] Preferably, an upper magnet is installed on the plug, and a magnetic block is installed on the top of the inner part of the feeding port, the magnetic block and the upper magnet repel each other, and the plug is plugged at the end of the input pipe.

[0013] Preferably, conveying cylinders are installed on both sides of the crushing box, an input pipe is installed between the top of the conveying cylinder and the crushing box, and an output pipe is installed between the bottom of the conveying cylinder and the crushing box.

[0014] Preferably, an upper limit block is installed on the inner side of the crushing box, the bottom of the upper limit block contacts the top of the filter plate, a through hole is opened inside the limit plate, the through hole is connected to the output pipe, and a lower limit block is installed on the inner wall of the limit plate.

[0015] Preferably, an inner motor is installed at the bottom of the conveying cylinder, and an auger is installed at the output end of the inner motor.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a filter plate, a counterweight block and a lower limit block, wherein the lower limit block is installed on the inner wall of the limit plate, and the filter plate is rotatably connected to the inside of the crushing box. When the weight of the grain raw materials accumulated on the filter plate is relatively light, the filter plate remains horizontal, and the horizontal filter plate allows the grain raw materials of a smaller volume to pass through the filter plate smoothly. When the weight of the grain raw materials accumulated on the filter plate is greater than the weight of the counterweight block, the weight of the grain raw materials causes the filter plate to rotate downward, causing the filter plate to tilt downward so that the grain raw materials above slide to the through-hole position. The filter plate can be in two states, which can fully screen out the grain raw materials accumulated above the filter plate, greatly reduce the accumulation of the grain raw materials of a smaller volume on the filter plate, reduce the grain raw material refinement time, and greatly improve work efficiency.

[0017] 2. The present invention is provided with a pull rope, a plug, a magnetic block and an upper magnet. When the filter plate rotates, the pull rope is pulled, and the pull rope pulls the plug to separate from the input pipe, so that the grain raw materials that have undergone the first crushing fall back onto the crushing roller. When the pull rope is not pulled, the repulsive force between the magnetic block and the upper magnet causes the plug to engage with the input pipe, limiting the grain raw materials inside the conveying cylinder, thereby preventing the uncrushed grain raw materials from mixing with the crushed grain raw materials.

[0018] 3. The present invention is provided with lower magnets. When the filter plate rotates and tilts, the lower magnets on both sides attract each other. The attraction between the lower magnets on both sides is smaller than the weight of the counterweight block. The attraction of the lower magnets on both sides prolongs the tilting time of the filter plate, thereby allowing the grain raw materials accumulated above the filter plate to slide into the conveying cylinder.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 5 , the present invention provides a technical solution: A grain raw material refining device for food production comprises a crushing box 1, a feeding port 2 and a crushing roller 13, wherein the feeding port 2 is arranged at the top of the crushing box 1, the crushing roller 13 is rotatably connected to the inside of the crushing box 1 via an axle, and the bottom of the crushing box 1 is rotatably connected to a filter plate 15 via an axle; an external motor 5 is installed at the front side of the crushing box 1, a gear 4 is installed at the end of the axle of the crushing roller 13, the gear 4 is located at the outside of the crushing box 1, the output end of the external motor 5 is fixedly connected to the shaft of the gear 4 on one side, the gears 4 on the left and right sides are meshed with each other, and a feeding port 23 is arranged at the bottom of the crushing box 1.

[0023] The external motor 5 is connected to a power source, and the operation of the external motor 5 drives the connected gear 4 to rotate. Since the gears 4 on the left and right sides are meshed with each other, the rotating gear 4 drives the gear 4 next to it to rotate synchronously, and the gears 4 on the left and right sides rotate in opposite directions. During the rotation of the gear 4, the crushing roller 13 is driven to rotate synchronously. Then, the grain raw materials for food production are put into the crushing box 1 through the feeding port 2, and the grain raw materials fall to the middle position of the crushing rollers 13 on both sides. The grain raw materials passing through the crushing rollers 13 are crushed by the crushing rollers 13, and the crushed grain raw materials fall onto the filter plate 15. The filter plate 15 filters the crushed grain raw materials, and the smaller grain raw materials fall through the filter plate 15, and the larger grain raw materials stay on the filter plate 15. The fallen grain raw materials are discharged through the discharge port 23.

[0024] A control mechanism is provided on the filter plate 15 to control the upward and downward rotation amplitude of the filter plate 15, so that the filtered grain raw materials will no longer be crushed. A limit plate 19 is installed on the inner side of the crushing box 1, and the inner wall of the limit plate 19 is in contact with the end of the filter plate 15. The curvature of the inner wall of the limit plate 19 is the same as the curvature formed by the rotation of the filter plate 15. The end of the filter plate 15 away from the limit plate 19 is in contact with each other. The control mechanism includes a counterweight 11, a rope 14, a pull rope 12 and a lower magnet 16. A counterweight 11 is placed inside the crushing box 1, and a rope 14 is provided between the upper end of the counterweight 11 and the top of the filter plate 15. A lower magnet 16 is installed at the bottom of the filter plate 15, and a guide rod 10 is installed at the bottom of the limit rod 9, and the counterweight 11 runs through the guide rod 10.

[0025] When the weight of the grain material piled on the filter plate 15 is greater than the weight of the counterweight block 11, the weight of the grain material causes the filter plates 15 on both sides to rotate downward, and the rotation of the filter plates 15 pulls the rope 14, and the rope 14 pulls the counterweight block 11 to move upward; An upper limit block 20 is installed on the inner side of the crushing box 1, and the bottom of the upper limit block 20 contacts the top of the filter plate 15. A through hole 18 is opened inside the limit plate 19, and the through hole 18 is connected to the output pipe 25. A lower limit block 17 is installed on the inner wall of the limit plate 19; When the filter plate 15 rotates to fit with the lower limit block 17, the lower limit block 17 limits the filter plate 15. At this time, the top surface of the filter plate 15 is aligned with the through hole 18. At this time, the grain raw materials on the filter plate 15 slide downward due to their own weight and enter the inside of the conveying cylinder 3 through the through hole 18.

[0026] The lower magnets 16 on the left and right sides attract each other, and the attraction of the lower magnets 16 on the left and right sides is less than the weight of the counterweight 11. A horizontal limit rod 9 and a mounting rod 26 are installed on the top of the crushing box 1. The mounting rod 26 is located at the top of the limit rod 9, and the rope 14 passes around the top of the limit rod 9.

[0027] When the filter plates 15 on both sides remain in an inclined state, the spacing between the lower magnets 16 on both sides is reduced, and suction is generated between the lower magnets 16 on both sides. When the suction of the lower magnets 16 and the weight of the grain raw materials on the filter plate 15 are greater than the weight of the counterweight 11, the filter plate 15 remains in an inclined position, and the grain raw materials on the filter plate 15 continue to slide into the conveying cylinder 3. When the suction of the lower magnets 16 and the weight of the grain raw materials on the filter plate 15 are less than the weight of the counterweight 11, the counterweight 11 moves downward, and the counterweight 11 moves downward to pull the rope 14, and the rope 14 pulls the filter plate 15 to rotate upward. When the filter plate 15 rotates to contact the upper limit block 20, the upper limit block 20 limits the filter plate 15, and the filter plate 15 remains horizontal and continues to perform the filtering function.

[0028] Plugs 8 are passed through both ends of the mounting rod 26. A pull rope 12 is arranged between the end of the plug 8 away from the crushing box 1 and the bottom of the counterweight 11. The weight of the counterweight 11 is greater than the repulsive force between the upper magnets 7 on both sides.

[0029] When the counterweight 11 moves upward, the counterweight 11 pulls the pull rope 12, and the pull rope 12 pulls the plug 8 to the middle position, and the plug 8 is gradually separated from the input pipe 24, so that the grain material inside the conveying cylinder 3 can fall normally. During the movement of the plug 8, the upper magnet 7 is driven to move synchronously, and the distance between the upper magnet 7 and the magnetic block 6 is reduced. When a repulsive force is generated between the upper magnet 7 and the magnetic block 6, since the weight of the counterweight 11 is greater than the repulsive force between the upper magnets 7 on both sides, the upper magnets 7 on both sides can continue to move to the middle position.

[0030] An upper magnet 7 is installed on the plug 8 , and a magnetic block 6 is installed on the top of the feeding port 2 . The magnetic block 6 and the upper magnet 7 repel each other, and the plug 8 is plugged at the end of the input pipe 24 .

[0031] When the counterweight 11 moves downward, the pull rope 12 is no longer pulled and is in a relaxed state. At this time, the repulsive force between the upper magnets 7 on both sides causes the upper magnets 7 and the plug 8 to move toward the side close to the input pipe 24, so that the plug 8 is blocked at the end of the input pipe 24, thereby preventing the grain raw materials inside the conveying cylinder 3 from mixing with the newly-added grain raw materials, and preventing the mixing from affecting the subsequent refinement of the refined grain raw materials, thereby greatly reducing the refinement time.

[0032] Conveying cylinders 3 are installed on both sides of the crushing box 1, an input pipe 24 is installed on the top of the conveying cylinder 3 and the crushing box 1, an output pipe 25 is installed on the bottom of the conveying cylinder 3 and the crushing box 1, an inner motor 21 is installed at the bottom of the conveying cylinder 3, and an auger 22 is installed at the output end of the inner motor 21.

[0033] During the refinement process, the power supply of the internal motor 21 is turned on, and the internal motor 21 rotates the auger 22. The rotation of the auger 22 causes the grain raw materials at the bottom position inside the conveying cylinder 3 to be transported upward, and the grain raw materials enter the upper part of the crushing box 1 through the input pipe 24, so that the crushed grain raw materials can be crushed and refined again. The grain raw materials can be refined multiple times to reduce the volume of the grain raw material particles and improve the taste of the food.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
