However, after the corn kernels are cleaned, it is not convenient to drain the water on the surface of the corn kernels. Corn kernels mixed with a large amount of water are easy to clump together during grinding, which affects the grinding efficiency and powder quality. In addition, during the grinding process, heat will be generated due to factors such as friction between corn kernels and friction during equipment operation.

[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.

[0021] Through the above technical solution, corn kernels are placed in the crushing barrel 6, and the first motor 7 is started to drive the rotating rod 8 to rotate counterclockwise, so that the grinding sheet 9 rotates, and the corn kernels are ground into powder by the rotating grinding sheet 9. The qualified corn powder passes through the screen 10 and falls into the receiving hopper 11, and the unqualified corn kernels remain in the crushing barrel 6 for further grinding and are directly and completely ground into powder.

[0022] Specifically, a material discharge chute is provided at the top of the crushing barrel 6, and a partition 12 is slidably connected to the inside of the crushing barrel 6. One side of the partition 12 extends to the inside of the material discharge chute. A second spring 13 is fixedly connected to the inside of the crushing barrel 6, and one end of the second spring 13 is fixedly connected to the partition 12. A toggle assembly is provided inside the crushing barrel 6.

[0023] Through the above technical scheme, the second spring 13 is arranged to cooperate with the partition 12 to block the feed chute, so as to prevent the corn particles poured into the box body 1 from entering the crushing barrel 6 at one time. Excessive corn particles will affect the grinding effect of the grinding sheet 9, and avoid excessive corn particles splashing out of the crushing barrel 6 when grinding the corn particles. When the first motor 7 is started, the partition 12 is cooperated with the toggle assembly to slide in the crushing barrel 6, and the second spring 13 is pressed. The partition 12 opens the feed chute while sliding, so that the corn particles accumulated above the partition 12 fall into the crushing barrel 6. With the start of the first motor 7, the toggle assembly is controlled to intermittently push the partition 12, thereby reciprocating, so that the corn particles above the partition 12 intermittently and quantitatively enter the crushing barrel 6.

[0024] Specifically, the toggle assembly includes two first gears 14, which are fixedly mounted on the outer wall of the rotating rod 8 and are symmetrically mounted. The inner wall of the crushing barrel 6 is symmetrically rotatably connected to the two first rotating shafts 15, the outer walls of the two first rotating shafts 15 are fixedly connected to the second gears 16, the two first gears 14 are respectively meshed with the two second gears 16, the circumference of the second gear 16 is three times the circumference of the first gear 14, the outer walls of the two first rotating shafts 15 are fixedly connected to the push rods 17, the inner walls of the two push rods 17 are slidably connected to the push blocks 18, the inside of the push rods 17 is fixedly connected to the third spring 19, one end of the third spring 19 is fixedly connected to the push block 18, the outer wall of the push block 18 is set to a symmetrical inclined surface, the bottom of the partition 12 is provided with a slot 20 used to cooperate with the push block 18, and the elastic force of the third spring 19 is greater than the elastic force of the second spring 13.

[0025] Through the above technical solution, the rotating rod 8 rotates counterclockwise while driving the two first gears 14 to rotate counterclockwise. When the two first gears 14 rotate counterclockwise for three circles, the two second gears 16 are driven to rotate clockwise for one circle, so that the two first rotating shafts 15 rotate clockwise for one circle, and the two ejector rods 17 rotate clockwise for one circle. When the ejector rod 17 rotates to the bottom of the slot 20, under the action of the third spring 19, the ejector block 18 extends into the slot 20. As the ejector rod 17 rotates clockwise, the ejector block 18 is rotated clockwise. The block 18 drives the slot 20 to slide to one side, driving the partition 12 to slide in the crushing barrel 6, and compressing the second spring 13. When the second spring 13 is compressed to the limit, the slot 20 pushes the inclined surface of the outer wall of the top block 18, causing the top block 18 to slide in the top rod 17, and compressing the third spring 19. After the top block 18 is no longer driven, the partition 12 is reset under the action of the second spring 13, and the material discharge chute is blocked again. Thus, the reciprocating movement drives the material discharge chute to open intermittently as the rotating rod 8 rotates counterclockwise.

[0026] Specifically, two first support frames 21 are symmetrically fixedly connected to the inner wall of the box body 1, a second motor 22 is fixedly connected between the two first support frames 21, a reciprocating screw 23 is fixedly connected to the output end of the second motor 22, an outer wall of the reciprocating screw 23 is connected to a slider 24 through a screw nut pair, an outer wall of the slider 24 is fixedly connected to a material holding barrel 25, a plurality of drain grooves 38 are equidistantly provided on the inner wall of the material holding barrel 25, a plurality of discharge ports 37 are equidistantly provided on the bottom of the material holding barrel 25, and a material blocking assembly is provided at the bottom of the discharge port 37.

[0027] Through the above technical scheme, the corn grains are poured into the material holding barrel 25, and the material blocking assembly is used to block the discharge port 37 so that the corn grains remain in the material holding barrel 25. The second motor 22 is started to drive the reciprocating screw 23 to rotate clockwise, so that the slider 24 rotates accordingly, and drives the material holding barrel 25 to rotate. The rotating material holding barrel 25 forms a centrifugal force to throw out the water mixed in the corn grains. The thrown out water can flow out along the drain trough 38 and separate from the corn grains. After the corn grains and the water are separated, the material blocking assembly is separated from the discharge port 37, and the corn grains fall onto the support platform 5 along the discharge port 37, and fall into the crushing barrel 6 along the inclined surface of the support platform 5.

[0028] Specifically, the material blocking assembly includes a third support frame 31, which is fixedly mounted on the inner wall of the box body 1 and is located below the material holding barrel 25, the inner wall of the third support frame 31 is fixedly connected with a support ring 32, the inner wall of the support ring 32 is slidably connected with a second sliding shaft 33, the top of the second sliding shaft 33 is fixedly connected with a blocking ring 36, the top of the blocking ring 36 is set as an annular inclined surface, the blocking ring 36 fits the bottom of the discharge port 37, the bottom of the second sliding shaft 33 is fixedly connected to a limiting block 34, the outer wall of the second sliding shaft 33 is sleeved with a fifth spring 35, the top of the fifth spring 35 is fixedly connected to the blocking ring 36, the bottom of the fifth spring 35 is fixedly connected to the support ring 32, and the inner wall of the box body 1 is provided with an adjustment unit.

[0029] Through the above technical scheme, the fifth spring 35 is set to make the baffle ring 36 fit the bottom of the material barrel 25, block the discharge port 37, and make the corn grains stay in the material barrel 25. After the material barrel 25 rotates to dry the moisture in the corn grains, the reciprocating screw rod 23 is driven counterclockwise by the second motor 22, and cooperates with the adjustment unit to make the material barrel 25 move up and down reciprocatingly. When the material barrel 25 moves upward, it disengages from the baffle ring 36. After losing the obstruction of the baffle ring 36, the corn grains in the material barrel 25 pass through the discharge port 37 and fall on the baffle ring 36, and slide along the inclined surface of the baffle ring 36 to the support platform 5. After the corn grains in the material barrel 25 are discharged, the material barrel 25 moves downward and fits with the baffle ring 36 again.

[0030] Specifically, the adjustment unit includes two second support frames 26, and the two second support frames 26 are symmetrically fixedly installed on the inner wall of the box body 1. The inner walls of the two second support frames 26 are fixedly connected with limit plates 27, and the two limit plates 27 are both in contact with the outer wall of the material bucket 25. The inner walls of the two limit plates 27 are slidably connected with blocks 29, and the outer walls of the two blocks 29 are set as inclined surfaces. The interiors of the two limit plates 27 are fixedly connected with fourth springs 28, and the two fourth springs 28 are respectively fixedly connected to the two blocks 29. The outer wall of the material bucket 25 has two symmetrical slots 30, and one end of the two blocks 29 extends to the inside of the two slots 30 respectively.

[0031] By the above technical solution, the second motor 22 is started to drive the reciprocating screw 23 to rotate clockwise, so that the slider 24 rotates clockwise, and the material holding barrel 25 rotates clockwise. When the slot 30 rotates to the position of the block 29, the block 29 enters the slot 30 under the action of the fourth spring 28. As the reciprocating screw 23 continues to rotate, the inclined surface on one side of the block 29 presses against the slot 30. Under the pressure of the slot 30, the block 29 moves into the limit plate 27, pressing the fourth spring 28. As a result, when the reciprocating screw 23 rotates clockwise, the slider 24 rotates clockwise, and the material holding barrel 25 rotates clockwise. The block 24 and the material bucket 25 rotate clockwise, the second motor 22 is started, and the reciprocating screw rod 23 rotates counterclockwise, so that the slider 24 rotates counterclockwise, and the material bucket 25 rotates counterclockwise. When the slot 30 rotates to the position of the block 29, under the action of the fourth spring 28, the block 29 enters the slot 30. As the reciprocating screw rod 23 continues to rotate, the straight surface of one side of the block 29 presses against the slot 30 and cannot rotate. Therefore, when the reciprocating screw rod 23 rotates counterclockwise, it drives the slider 24 to move up and down reciprocatingly, so that the material bucket 25 moves up and down reciprocatingly.

[0032] Specifically, the cooling unit includes two water inlets 39, and the two water inlets 39 are respectively opened on the top of the two support platforms 5. Two U-shaped grooves 40 are symmetrically opened inside the crushing barrel 6, and a connecting groove 41 is opened between the two water inlets 39 and the two U-shaped grooves 40. The outer wall of the crushing barrel 6 is symmetrically opened with two water outlets 42, and the two water outlets 42 are respectively connected to the two U-shaped grooves 40. The outer wall of the crushing barrel 6 and the bottom of the water outlet 42 are symmetrically fixedly connected with two guide plates 43, one end of the two guide plates 43 extends to the outside of the box body 1, and the two guide plates 43 are both installed at an angle.

[0033] Through the above technical scheme, the water mixed in the corn particles is thrown out from the drain groove 38, falls on the support platform 5, and slides down along the inclined surface of the support platform 5. When the water slides to the water inlet 39, it enters the support platform 5 along the water inlet 39, and enters the U-shaped groove 40 along the connecting groove 41. The water entering the U-shaped groove 40 can cool the crushing barrel 6 to prevent the crushing barrel 6 from gradually heating up due to grinding, and with the continuous water inflow of the connecting groove 41, the water that has heated up after cooling and use can be merged. When the water level in the U-shaped groove 40 reaches the position of the water outlet 42, the excess water is discharged from the box body 1 along the water outlet 42, and the U-shaped groove 40 is set to give the water newly entering the crushing barrel 6 sufficient fusion time, which has a good cooling effect on the crushing barrel 6.

[0034] Specifically, the inner wall of the box body 1 is symmetrically rotatably connected to two second rotating shafts 44 located above the support platform 5. One end of the two second rotating shafts 44 is fixedly connected to a cam 45. The cam 45 is used in conjunction with the support platform 5. A linkage assembly is provided between the reciprocating screw 23 and the second rotating shaft 44.

[0035] Through the above technical solution, when the second motor 22 is started, the two second rotating shafts 44 are driven to rotate through the linkage assembly, so that the two cams 45 are rotated. When the raised ends of the two cams 45 rotate downward, the two support platforms 5 are pushed to move downward, so that the crushing barrel 6 moves downward, and the two connecting blocks 3 are driven to move downward, and the two first springs 4 are pressed. When the raised ends of the two cams 45 rotate upward, under the action of the two first springs 4, the two connecting blocks 3 are pushed to move upward, and the crushing barrel 6 moves upward. In this way, the second motor 22 is started and the crushing barrel 6 is driven to shake up and down to prevent corn powder from clogging the screen 10 and affecting the discharge of the material.

[0036] Specifically, the linkage assembly includes two third rotating shafts 46, which are rotatably connected to the inner wall of the box body 1, and the two third rotating shafts 46 are symmetrically installed. One end of the two third rotating shafts 46 is fixedly connected to the second bevel gear 51, the outer wall of the reciprocating screw 23 is fixedly connected to the first bevel gear 50, and the two second bevel gears 51 are meshingly connected to the first bevel gear 50. The outer walls of the two third rotating shafts 46 are fixedly connected to the first pulley 47, and the outer walls of the two second rotating shafts 44 are fixedly connected to the second pulley 48. The first pulley 47 and the second pulley 48 are connected for transmission by a transmission belt 49, and a baffle 52 is fixedly connected to the outer wall of the reciprocating screw 23 and located above the second bevel gear 51.

[0037] Through the above technical solution, the reciprocating screw 23 rotates while driving the first bevel gear 50 to rotate, causing the two second bevel gears 51 to rotate, driving the two third rotating shafts 46 to rotate, causing the two first pulleys 47 to rotate, and through the two transmission belts 49, driving the two second pulleys 48 to rotate, causing the two second rotating shafts 44 to rotate. The baffle 52 can be used to protect the first bevel gear 50 to prevent corn particles from falling on the first bevel gear 50.

[0038] An operating method for a grinding device for processing corn powder, the operating method is applicable to the above-mentioned grinding device for processing corn powder, and the steps of the operating method are as follows: S1: Pour corn kernels into the material storage barrel 25, start the second motor 22 to control the reciprocating screw 23 to rotate clockwise, drive the material storage barrel 25 to rotate, and throw out the water mixed in the corn kernels; S2: After the water in the corn kernels is thrown out, the second motor 22 is started to control the reciprocating screw 23 to rotate counterclockwise, and the clamping block 29 is used to limit the position, so that the material barrel 25 moves up and down, and the discharge port 37 is opened, so that the corn kernels in the material barrel 25 fall into the crushing barrel 6; S3: Start the first motor 7 to drive the rotating rod 8 to rotate counterclockwise, so that the grinding sheet 9 rotates to grind the corn particles into powder. The qualified corn powder passes through the screen 10 and falls into the receiving hopper 11.

[0039] When in use, corn grains are poured into the material barrel 25, and the fifth spring 35 is provided to make the retaining ring 36 fit the bottom of the material barrel 25, block the discharge port 37, and make the corn grains stay in the material barrel 25, start the second motor 22, drive the reciprocating screw rod 23 to rotate clockwise, make the slider 24 rotate clockwise, and make the material barrel 25 rotate clockwise. When the slot 30 rotates to the position of the block 29, the block 29 enters the slot 30 under the action of the fourth spring 28. As the reciprocating screw rod 23 continues to rotate, the inclined surface on one side of the block 29 presses against the slot 30. Under the extrusion of the slot 30, the block 29 moves into the limit plate 27, pressing the fourth spring 28. As a result, when the reciprocating screw rod 23 rotates clockwise, it drives the slider 24 and the material barrel 25 to rotate clockwise. The barrel 25 rotates clockwise, and the rotating material barrel 25 forms a centrifugal force to throw out the water mixed in the corn particles. The thrown water can flow out along the drain groove 38 and separate from the corn particles. After the corn particles and the water are separated, the second motor 22 is started to drive the reciprocating screw rod 23 to rotate counterclockwise, so that the slider 24 rotates counterclockwise, and drives the material barrel 25 to rotate counterclockwise. When the slot 30 rotates to the position of the block 29, under the action of the fourth spring 28, the block 29 enters the slot 30. As the reciprocating screw rod 23 continues to rotate, the straight surface of one side of the block 29 presses against the slot 30 and cannot rotate. Therefore, when the reciprocating screw rod 23 rotates counterclockwise, it drives the slider 24 to move up and down reciprocatingly, so that the material barrel 25 moves up and down reciprocatingly. When the material barrel 25 moves upward , and disengages from the baffle ring 36. After losing the obstruction of the baffle ring 36, the corn particles in the material bucket 25 pass through the discharge port 37 and fall on the baffle ring 36, and slide along the inclined surface of the baffle ring 36 to the support platform 5. After the corn particles in the material bucket 25 are discharged, the material bucket 25 moves downward and fits with the baffle ring 36 again. The corn particles that fall on the support platform 5 are accumulated on the partition 12. The second spring 13 is provided to cooperate with the partition 12 to block the discharge chute to prevent the corn particles poured into the box body 1 from entering the crushing barrel 6 at one time. Too many corn particles will affect the grinding effect of the grinding sheet 9. The first motor 7 is started to drive the rotating rod 8 to rotate counterclockwise. The rotating rod 8 rotates counterclockwise while driving the two first gears 14 to rotate counterclockwise. The two first gears 14 rotate counterclockwise. When the push rod 17 rotates three times, it drives the two second gears 16 to rotate one circle clockwise, makes the two first rotating shafts 15 rotate one circle clockwise, and drives the two push rods 17 to rotate one circle clockwise. When the push rod 17 rotates to the bottom of the slot 20, under the action of the third spring 19, the push block 18 extends into the slot 20. As the push rod 17 rotates clockwise, the slot 20 is pushed to slide to one side by the push block 18, driving the partition 12 to slide in the crushing barrel 6, pressing the second spring 13. When the second spring 13 is compressed to the limit, the slot 20 pushes the inclined surface of the outer wall of the push block 18, so that the push block 18 slides in the push rod 17, pressing the third spring 19. After the push of the push block 18 is lost, under the action of the second spring 13, the partition 12 is reset to block the material discharge chute again, thus reciprocating.As the rotating rod 8 rotates counterclockwise, the feeding chute is opened intermittently, so that the corn grains above the partition 12 intermittently and quantitatively enter the crushing barrel 6. The rotating rod 8 rotates counterclockwise and the grinding sheet 9 rotates. The corn grains are ground into powder by the rotating grinding sheet 9. The corn powder that is ground to the standard passes through the screen 10 and falls into the receiving hopper 11. The corn grains that are not ground to the standard remain in the crushing barrel 6 and continue to be ground. They are directly and completely ground into powder. The water mixed in the corn grains is thrown out from the drain trough 38 and falls on the support table 5. 5, when the water slides to the water inlet 39, it enters the support platform 5 along the water inlet 39, and enters the U-shaped groove 40 along the connecting groove 41. The water entering the U-shaped groove 40 can cool the crushing barrel 6 to prevent the crushing barrel 6 from gradually heating up due to grinding, and with the continuous water inflow of the connecting groove 41, the water heated up after cooling can be merged. When the water level in the U-shaped groove 40 reaches the position of the water outlet 42, the excess water is discharged from the box body 1 along the water outlet 42, and the newly entered water can be given The water in the crushing barrel 6 has sufficient fusion time, which has a good cooling effect on the crushing barrel 6. The reciprocating screw 23 rotates while driving the first bevel gear 50 to rotate, so that the two second bevel gears 51 rotate, drive the two third rotating shafts 46 to rotate, and the two first pulleys 47 rotate. The two transmission belts 49 are used to drive the two second pulleys 48 to rotate, so that the two second rotating shafts 44 rotate. The baffle 52 is used to protect the first bevel gear 50 to prevent corn particles from falling on the first bevel gear 50. The two second rotating shafts 44 The two cams 45 are driven to rotate at the same time. When the raised ends of the two cams 45 rotate downward, the two support platforms 5 are pushed downward, so that the crushing barrel 6 moves downward, driving the two connecting blocks 3 to move downward, and pressing the two first springs 4. When the raised ends of the two cams 45 rotate upward, the two first springs 4 push the two connecting blocks 3 to move upward, driving the crushing barrel 6 to move upward, and thus reciprocating. When the second motor 22 is started, the crushing barrel 6 is driven to shake up and down to prevent corn powder from clogging the screen 10 and affecting the feeding.
