Description

Technical Field

[0001] The utility model relates to the technical field of agricultural product processing, and particularly relates to a grain milling device for primary processing of agricultural products. Background Technique

[0002] Grains cover a wide range, including miscellaneous grains such as rice, wheat, millet, and soybeans. After being harvested, grains need to be processed. The main working steps for primary processing of grains mainly include cleaning, drying, hulling, milling, and screening.

[0003] After retrieval, as disclosed in the Chinese patent document, a milling device for grain processing [Application No.: CN202123156922.6]. This kind of milling device for grain processing includes a milling outer shell. One side of the top of the milling outer shell is provided with a feeding box. The bottom of the milling outer shell is provided with a discharge bottom opening. Two milling rollers are rotatably connected inside the milling outer shell, and the ends of the two milling rollers are both connected to a driving motor. A hydraulic telescopic member is provided on the top of the milling outer shell. A telescopic rod is arranged inside the hydraulic telescopic member. The bottom end of the telescopic rod is provided with a reset backing plate, and the reset backing plate is located inside the milling outer shell and directly above the two milling rollers.

[0004] The device disclosed in this patent can push the grains towards the position where the milling rollers are located to ensure the efficiency of milling the grains. However, when using this device, it is necessary for the staff to adjust the position of the telescopic rod while feeding, so that the grains can smoothly fall through the feeding box onto the surface of the milling rollers. This process is rather inconvenient and it is easy to occur that the grains are difficult to fall onto the surface of the milling rollers for milling because the staff does not lift the telescopic rod. In addition, this device can only mill the grains once, and some particulate matter remaining after the primary milling of the grains still needs to be processed again using additional equipment, which is rather time-consuming and laborious.

An adjusting mechanism 3 is installed at the top of the hollow box 2. A backing plate 4 is fixedly connected to the bottom of the adjusting mechanism 3. Both sides of the top of the backing plate 4 are fixedly connected with baffle plates 5. The surface of the baffle plates 5 is in contact with the inner wall of the hollow box 2. Through the setting of the baffle plates 5, the possibility of grains moving to the backing plate 4 and the adjusting plate 33 can be reduced. Arc-shaped grooves are opened on both sides of the bottom of the backing plate 4. The inner wall of the arc-shaped grooves is in contact with the surface of the milling roller 7. Two milling rollers 7 are rotatably connected to the inner wall of the processing box 1. Guide plates 8 are fixedly connected to both sides of the inner wall of the processing box 1.

A driving mechanism 10 is installed on the surface of the U-shaped plate 9. A connecting shaft 11 and a long rod 12 are rotatably connected to the inner surface of the U-shaped plate 9. One end of the connecting shaft 11 rotatably penetrates the processing box 1 and is fixedly connected to one end of one of the milling rollers 7. Belt pulleys 13 are fixedly sleeved on the surfaces of the long rod 12 and the driving mechanism 10. A belt is drivingly connected to the surfaces of the two belt pulleys 13. The long rod 12 rotatably penetrates the surface of the processing box 1 and extends into the interior of the processing box 1. One end of the long rod 12 is fixedly connected to a milling disc 16. Limiting grooves are opened on the surface of the milling disc 16. Extension plates 14 and rectangular plates 15 are fixedly connected to both sides of the inner wall of the processing box 1 respectively. The surfaces of the extension plates 14 and the rectangular plates 15 are in contact with the inner wall of the limiting grooves. By the combined use of the extension plates 14 and the rectangular plates 15 and the limiting grooves, the stability of the position of the milling disc 16 can be increased.

An auxiliary milling mechanism 17 is installed on the inner wall of the processing box 1 and is fixedly connected with a feeding hopper 18. The feeding hopper 18 is arranged below the milling rollers 7. The feeding hopper 18 can receive the grains milled by the milling rollers 7.

[0025] The adjusting mechanism 3 includes a slide rod 31, a pressing plate 32, an adjusting plate 33, and a tension spring 34. The slide rod 31 slidably penetrates the hollow box 2. The pressing plate 32 is fixedly connected to the top of the slide rod 31. The number of the slide rods 31 is two. The adjusting plate 33 is fixedly connected to the bottom of the slide rod 31. The tension spring 34 is sleeved on the surface of the slide rod 31. The two ends of the tension spring 34 are respectively fixedly connected to the top of the inner wall of the hollow box 2 and the top of the adjusting plate 33. The backing plate 4 is fixedly connected to the bottom of the adjusting plate 33. After the grains are put into the interior of the processing box 1, the staff can press the pressing plate 32. The adjusting plate 33 drives the backing plate 4 to descend and presses the grains downward so that the milling rollers 7 can better mill the grains. Thereafter, under the action of the elastic force of the tension spring 34, the adjusting plate 33 can drive the backing plate 4 to rise to reduce the influence of the adjusting mechanism 3 and the backing plate 4 on subsequent feeding.

[0026] The driving mechanism 10 includes a motor 101, a rotating shaft 102, and a gear disc 103. The motor 101 is fixedly connected to the surface of the C-shaped plate 9.

The two gear discs 103 are meshed with each other. One side belt pulley 13 is fixedly sleeved on the surface of the rotating shaft 102. When the staff starts the motor 101, the rotating shaft 102 rotates, which can drive the gear disc 103 fixedly sleeved on its surface to rotate. At this time, the other gear disc 103 can drive the connecting shaft 11 to rotate. Accordingly, the two milling rollers 7 can rotate in opposite directions to mill the grains. At the same time, the cooperation of the belt and the belt pulley 13 can drive the long rod 12 to rotate;

[0027] The motor 101 is electrically connected to the controller. When the device is in use, the staff can start the motor 101 through the controller.

Both sides of the surface of the disc 173 are fixedly connected to the surfaces of the fixing plate 171 and the arc plate 172. A feeding groove is formed at the top of the disc 173. The lower surface of the feeding hopper 18 is in contact with the inner wall of the feeding groove. While the long rod 12 drives the milling disc 16 to rotate, the cooperation of the milling disc 16 and the disc 173 can mill the grains entering from the feeding groove again. The grains after being milled again are discharged through the discharging groove 19.

[0029] Working principle: The staff puts the grains into the inside of the processing box 1 through the feeding hopper 6. At the same time, the staff starts the motor 101 through the controller. The cooperation of the rotating shaft 102, the gear disc 103, and the connecting shaft 11 can drive the two milling rollers 7 to rotate to mill the grains for the first time. During this process, the staff can press the pressing plate 32, and the adjusting plate 33 drives the backing plate 4 to descend to limit the position of the grains and press the grains against the surface of the milling roller 7 to ensure the milling efficiency of the milling roller 7 for the grains. After that, the milled grains fall into the inside of the feeding hopper 18. The feeding hopper 18 guides the grains between the disc 173 and the milling disc 16 through the feeding groove. At the same time, under the cooperation of the belt pulley 13 and the belt, the long rod 12 drives the milling disc 16 to rotate to mill the grains again, thereby improving the milling effect of the grains.
