Description

Technical Field

[0001] The invention relates to the technical field of yam powder grinding, in particular to an automatic grading and grinding production line for selenium-rich loess iron stick yam powder. Background Art

[0002] Selenium-rich loam iron stick yam is a variety of yam with unique nutritional value and health benefits. Selenium-rich loam iron stick yam usually has uneven thickness and natural curves, rough skin, and rust-like reddish-brown spots. This is the result of the deposition of iron and other minerals in the loam on the surface of the yam. The yam has a solid texture, is not easy to break, has a delicate cross-section, is white or slightly yellow, and is rich in mucus. Selenium-rich loam iron stick yam is sweet and delicate in taste, and is an excellent choice for making various delicacies.

[0003] After searching, the Chinese patent with announcement number CN220048443U discloses a yam powder grinding machine, including a collecting barrel, a stirring motor is arranged at the bottom of the collecting barrel, a stirring frame is welded on the outer wall of the stirring rod, a grinding barrel is arranged on the top of the collecting barrel, a shaking motor is arranged at the bottom of the grinding barrel, a sieve plate is arranged on the side wall of the fixed block, a fixed grinding seat is also sleeved on the inner wall of the grinding barrel, an ultraviolet disinfector is arranged at the bottom of the grinding barrel, a fixed sleeve is connected to the output end of the crushing motor, springs are welded on the outer walls on both sides of the partition, and a limited position block is welded at the end of the spring. A rotating grinding block is arranged at the bottom of the rotating crushing rod, which effectively facilitates the installation and disassembly of the rotating crushing rod to prevent the yam powder from agglomerating during the grinding process. Secondly, after the yam is ground, the stirring frame can be used to evenly stir the yam powder, and the ultraviolet disinfector can be used to better sterilize and disinfect the yam powder. However, this solution still has the following shortcomings in actual use: Although the ground yam powder can be graded through the sieve plate during the screening process, due to its small particle size, these fine powder particles are prone to agglomeration when accumulated on the surface of the sieve plate. This agglomeration will not only reduce the permeability of the sieve plate, but may also cause the sieve holes to be gradually blocked, which will seriously affect the grading and screening efficiency of the sieve plate, making the screening process slow and ineffective.

[0026] Reference Figure 8The cleaning mechanism includes: a fixed frame 105, which is fixedly mounted on the inner side wall of the grinding box 3, and the fixed frame 105 is located directly below the electric push rod 102; a brush plate 106, which is rotatably mounted on the end of the fixed frame 105 through a rotating rod, and the brush plate 106 is adapted to the grading screen 8, and the top surface of the brush plate 106 is provided with flexible bristles; an adjusting gear 107, which is fixedly sleeved on the outer wall of the rotating rod; an adjusting rack 108, which is arranged at the telescopic end of the electric push rod 102 through a sleeve ring, and the adjusting rack 108 is meshed with the adjusting gear 107, and the sleeve ring is connected to the grinding wheel through the telescopic frame. The inner wall of the grinding box 3 is fixedly connected; during the extension of the electric push rod 102, the sleeve ring can be driven to move, and the sleeve ring cannot rotate with the electric push rod 102. When the sleeve ring moves, the adjusting rack 108 can be driven, and the adjusting rack 108 is meshed with the adjusting gear 107, thereby driving the adjusting gear 107 and the brush plate 106 to rotate, so that the brush plate 106 rotates to the bottom of the grading screen 8 and is fixed, so that during the rotation of the grading screen 8, the flexible bristles on the brush plate 106 can be used to clean the sieve holes on the grading screen 8 to avoid blockage.

[0027] The specific working principle of the present invention is as follows: When in use, the selenium-rich loam iron stick yam can first be added to the cleaning and peeling machine 1 to clean and peel the selenium-rich loam iron stick yam. The cleaned and peeled selenium-rich loam iron stick yam can be directly put into the slicing feeder 2, and the selenium-rich loam iron stick yam can be sliced ​​in the slicing feeder 2 so as to be subsequently ground into selenium-rich loam iron stick yam powder. After the selenium-rich loam iron stick yam is sliced, it can enter the grinding box 3 and be located in the fixing ring 4. The working principle and connection method of the cleaning and peeling machine 1 and the slicing feeder 2 are existing mature technologies and will not be described in detail herein. When the yam slices are added to the grinding box 3, the driving motor 5 can be turned on to drive the grinding roller 66 to rotate through the driving rod 65. When the yam slices fall to the top surface of the grinding roller 66, they can be added between the grinding roller 66 and the grinding outer ring 64 under the action of centrifugal force. The yam slices can be ground between the grinding roller 66 and the grinding outer ring 64 by rotating the grinding roller 66, and the grinding patterns on the grinding roller 66 and the grinding outer ring 64 can ensure that the yam is fully ground. Before grinding, the staff can grind the yam powder according to the needs. The distance between the grinding roller 66 and the grinding outer ring 64 can be finely adjusted by rotating the threaded sleeve 610 during adjustment. Since the guide sleeve 67 is slidably connected to the driving rod 65 through the guide groove 68 and the guide block 69, and the guide sleeve 67 is rotatably connected to the threaded sleeve 610 and fixedly connected to the grinding roller 66, when the threaded sleeve 610 rotates and slides along the driving rod 65, the vertical position of the grinding roller 66 can be adjusted through the guide sleeve 67, so that the distance between the grinding roller 66 and the grinding outer ring 64 can be adjusted. The ground yam powder can fall into the grading screen 8 under the action of gravity, and the yam powder can be graded by screening the grading screen 8. The yam powder after screening can be discharged and collected through the discharge port 13, and the yam powder in the grading screen 8 can be taken out through the inspection port 11 for further secondary grinding. When the driving rod 65 rotates with the driving motor 5, the driving ball 92 can be driven to rotate through the connecting rod 91. When the driving ball 92 rotates, it can hit the fixed hemisphere 93, so that the use of the spring 63 drives the grinding outer ring 64 to slide along the fixed ring 4 through the slide groove 61 and the slide plate 62, so that the grinding outer ring 64 and the grinding roller 66 are Relative movement is generated, which further improves the grinding effect. During the reciprocating movement of the grinding outer ring 64 in the vertical direction, the knocking plate 96 can be squeezed by the transmission plate 910, so that the knocking plate 96 and the rotating shaft 95 can rotate along the bracket 94. Since the distance between the rotating shaft 95 and the knocking seat 98 is at least greater than the distance between the rotating shaft 95 and the transmission plate 910, the knocking plate 96 can be rotated under the action of the lever principle to stably knock the grading screen 8 through the knocking seat 98 and the knocking ball head 99, so that the grading screen 8 vibrates, and then the internal yam powder can be quickly graded and screened, reducing the occurrence of blockage. In the process of grading and screening the yam powder by the grading screen 8, the electric push rod 102 and the driving motor 101 can be turned on intermittently. When the electric push rod 102 is turned on and extended, the driving bevel gear 103 and the transmission bevel gear ring 104 can be meshed, and then the grading screen 8 is driven by the driving motor 101 to rotate along the support ring 7, so that the yam powder inside the grading screen 8 can be spread flat under the action of centrifugal force, which is helpful for screening. At the same time, the sleeve ring can be driven to move during the extension of the electric push rod 102, and the sleeve ring cannot rotate with the electric push rod 102. When the ring moves, the adjusting rack 108 can be driven, and the adjusting rack 108 is meshed with the adjusting gear 107, which can drive the adjusting gear 107 and the brush plate 106 to rotate, so that the brush plate 106 rotates to the bottom of the grading screen 8 and is fixed, so that during the rotation of the grading screen 8, the flexible bristles on the brush plate 106 can be used to clean the sieve holes on the grading screen 8 to avoid blockage. After tiling and cleaning are completed, the electric push rod 102 can be shortened, and the driving bevel gear 103 and the brush plate 106 can be reset to avoid affecting the normal use of the grading screen 8.
