Description

Technical Field

[0001] The invention relates to the technical field of corn processing devices, and in particular to a corn crushing device with a screening function. Background Art

[0002] In corn processing, corn often needs to be crushed and screened. The broken particles and corn flour in the corn crushed particles have different uses. The use of screening machines, using sieves of different diameters, can effectively separate broken particles of different sizes from corn flour, thereby increasing the use range of corn crushed particles. At the same time, the use of screening machines saves manpower and is simple and quick to operate.

[0003] However, when the screening machine is currently in use, the corn crushed particles fall directly onto the screen through the feed port, and there is no device to push the corn crushed particles evenly. As a result, the corn crushed particles accumulate on the screen during the feeding process, which easily causes the mesh of the screen to be blocked, resulting in the corn crushed particles being unable to be screened evenly and quickly, greatly affecting the screening speed.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] See attached Figure 1 -Attached Fig. 9 A corn crushing device with screening function comprises a bottom plate 1, a plurality of supporting spring rods 2 are evenly fixedly installed on the upper surface of the bottom plate 1, a screening box 3 is fixedly installed on the telescopic ends of the plurality of supporting spring rods 2, a crusher 4 connected to the inside of the screening box 3 is fixedly installed on the top of the screening box 3, a feed hopper 5 connected to the inside of the crusher 4 is fixedly installed on the top of the crusher 4, a vibration motor 6 is fixedly installed on the top of the screening box 3, a first roller 8 and a second roller 9 are rotatably installed between the inner walls on opposite sides of the screening box 3, one end of the second roller 9 is an open structure, and the front view shape of the first roller 8 and the second roller 9 is an I-shaped structure A transmission belt 10 is sleeved between the outer surfaces of both ends of the first roller 8 and the second roller 9, a screening belt 11 is fixedly installed between the two transmission belts 10, and a plurality of screening meshes 12 are evenly penetrated on the outer surface of the screening belt 11. A slag discharge mechanism is installed on the second roller 9, and a discharge port 28 is penetrated on the outer surface of the screening box 3 away from the second roller 9, and a discharge plate 29 is fixedly installed inside the discharge port 28 at an angle, and the end of the discharge plate 29 is in contact with the outer surface of the screening belt 11. A discharge hopper 7 connected to the interior of the screening box 3 is fixedly installed at the bottom of the screening box 3, and the qualified corn powder is discharged from the discharge hopper 7 for collection.

[0031] In this embodiment, the slag discharge mechanism includes a plurality of slag discharge ports 15 uniformly penetrating the circumferential direction and being opened on the outer periphery of the second roller 9. The inner wall of the slag discharge port 15 is rotatably installed with a scraper 16 and a baffle plate 20 through two torsion shafts. The scraper 16 and the baffle plate 20 are arranged at a right angle in the initial state. A pushing assembly is installed on the outer surface of the scraper 16. A discharge pipe 21 is inserted into the interior of the second roller 9. The discharge pipe 21 penetrates the outer surface of the screening box 3, and a discharge plate 24 is fixedly installed on the bottom wall of the discharge pipe 21 obliquely. The side of the discharge pipe 21 away from the first roller 8 is an opening structure. The discharge pipe 21 A toggle assembly is installed between the scraper 16, and the pushing assembly includes a pushing spring rod 19 fixedly installed on the outer surface of the scraper 16 on the side close to the material baffle plate 20. The toggle assembly includes two support plates 17 fixedly installed on the outer surface of the scraper 16 on the side close to the material baffle plate 20. The outer surfaces of the two support plates 17 on the adjacent sides are fixedly installed with toggle rods 18. A toggle block 22 is installed on the top wall of the discharge pipe 21 near its opening through a torsion shaft. The end of the toggle block 22 is a conical structure, and the outer surfaces on the opposite sides of the toggle block 22 are provided with makeshift grooves 23 for the adjacent ends of the two toggle rods 18 to pass through.

[0032] When in use, the corn particles to be crushed are poured from the feed hopper 5 into the crusher 4, and the crusher 4 crushes the corn particles. The crushed corn particles fall onto the screening belt 11 installed in the screening box 3, and the upper part of the screening belt 11 performs preliminary screening of the corn powder through the screening mesh 12. The corn powder with larger particles subsequently falls onto the discharge plate 29 as the screening belt 11 moves, and is discharged from the screening box 3 through the discharge port 28.

[0033] When the second roller 9 rotates clockwise, the scraper 16 will be driven to rotate accordingly, so that the scraper 16 can cooperate with the screening belt 11 to receive the corn crushed filtered out from the inner side of the screening belt 11. When the scraper 16 rotates to the shifting block 22, the end of the shifting block 22 will enter the slag discharge port 15 under the torsion action of the torsion shaft, so that the conical end of the shifting block 22 will abut against the two shifting rods 18, so that the conical end of the shifting block 22 can push the scraper 16 upward through the shifting rod 18 and the supporting plate 17. When the scraper 16 rotates, the spring rod 19 will push the baffle plate 20 toward the inside of the second roller 9, so that the baffle plate 20 opens the slag discharge port 15, so that the scraper 16 can pour the corn crushed into the discharge pipe 21, and the discharge plate 24 obliquely installed in the discharge pipe 21 will discharge the screened corn crushed. By separating the corn crushed from the corn powder, the screened corn crushed is discharged separately, which can effectively prevent the corn powder from escaping.

[0034] In this embodiment, a transverse plate 30 is fixedly installed between the inner walls on opposite sides of the screening box 3, and a plurality of strip openings 31 are evenly penetrated through the outer surface of the transverse plate 30. The upper surface of the transverse plate 30 is in contact with the lower surface of the lower part of the screening belt 11, and the opening width of the strip opening 31 is smaller than the diameter of the screening mesh 12, and the position of the strip opening 31 corresponds to the screening mesh 12.

[0035] When in use, the corn powder preliminarily screened out will fall to the inner side of the lower part of the screening belt 11. Since the lower surface of the lower part of the screening belt 11 is in contact with the horizontal plate 30 with the strip opening 31, and the strip opening 31 is aligned with the screening mesh 12, the strip opening 31 can form a smaller gap with the screening mesh 12, so that the corn powder after the preliminarily screening can be further and more finely screened out, so as to screen out qualified corn powder.

[0036] In this embodiment, a plurality of transmission posts 13 are evenly fixedly installed on the outer side of the transmission belt 10 , and a plurality of shifting posts 14 matching the transmission posts 13 are evenly fixedly installed on the outer surfaces of both ends of the first roller 8 and the second roller 9 in the circumferential direction.

[0037] When in use, the transmission column 13 is shifted by the shifting column 14 installed on the periphery of the first roller 8 and the second roller 9, so that the transmission belt 10 can drive the screening belt 11 to move stably.

[0038] In this embodiment, an intermittent rotation mechanism is installed between the first roller 8 and the base plate 1. The intermittent rotation mechanism includes a one-way bearing 25 installed at the rotation center of the first roller 8. The first roller 8 is equipped with a unidirectionally rotatable transmission gear 26 through the one-way bearing 25. A transmission rack 27 is fixedly installed on the upper surface of the base plate 1, and the transmission rack 27 is meshed with the transmission gear 26.

[0039] When the screening box 3 vibrates up and down, the transmission gear 26 installed with the first roller 8 through the one-way bearing 25 will move up and down accordingly. When the transmission gear 26 moves downward, it will drive the first roller 8 to rotate clockwise by a certain angle through the one-way bearing 25, so that the first roller 8 can drive the screening belt 11 to move the position of one or more screening meshes 12, thereby preventing the corn crumbs from falling into the same position and accumulating, affecting the screening effect.

[0040] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: when in use, the corn particles to be crushed are poured from the feed hopper 5 into the grinder 4, so that the grinder 4 crushes the corn particles, and the crushed corn particles fall onto the screening belt 11 installed in the screening box 3, so that the upper part of the screening belt 11 performs preliminary screening of the corn crushed particles through the screening mesh 12, and the corn crushed particles with larger particles subsequently fall onto the discharge plate 29 as the screening belt 11 moves, and are discharged from the screening box 3 through the discharge port 28;

[0041] The corn powder preliminarily screened out will fall to the inner side of the lower part of the screening belt 11. Since the lower surface of the lower part of the screening belt 11 is in contact with the horizontal plate 30 with the strip opening 31, and the strip opening 31 is aligned with the screening mesh 12, the strip opening 31 can form a smaller gap with the screening mesh 12, so that the corn powder preliminarily screened out can be further and more finely screened out, so as to screen out qualified corn powder.

[0042] When the second roller 9 rotates clockwise, the scraper 16 will be driven to rotate accordingly, so that the scraper 16 can cooperate with the screening belt 11 to pick up the corn crushed filtered out from the inner side of the screening belt 11. When the scraper 16 rotates to the shifting block 22, the end of the shifting block 22 will enter the slag discharge port 15 under the torsion of the torsion shaft, so that the conical end of the shifting block 22 will abut against the two shifting rods 18, so that the conical end of the shifting block 22 can push the scraper 16 upward through the shifting rod 18 and the support plate 17. When the scraper 16 rotates, the spring rod 19 will push the baffle plate 20 toward the inside of the second roller 9, so that the baffle plate 20 opens the slag discharge port 15, so that the scraper 16 pours the corn crushed into the discharge pipe 21, and the discharge plate 24 obliquely installed in the discharge pipe 21 discharges the screened corn crushed. By separating the corn crushed from the corn powder, the screened corn crushed is discharged separately, which can effectively prevent the corn powder from escaping.

[0043] By screening the corn crumbs through the continuously moving screening belt 11, the material can be prevented from accumulating on the screening belt 11, so that the corn crumbs can pass faster and the screening speed can be improved. In addition, the moving screening belt 11 can make the corn crumbs more evenly distributed on the screening belt 11, thereby enhancing the screening consistency.

[0044] When the vibration motor 6 is started, the support spring rod 2 is used to make the screening box 3 vibrate up and down, so that the screening belt 11 set in the screening box 3 can vibrate up and down accordingly, so as to make the falling corn crumbs vibrate, thereby improving the screening effect of the corn crumbs;

[0045] When the screening box 3 vibrates up and down, the transmission gear 26 installed with the first roller 8 through the one-way bearing 25 will move up and down accordingly. When the transmission gear 26 moves downward, it will drive the first roller 8 to rotate clockwise by a certain angle through the one-way bearing 25, so that the first roller 8 can drive the screening belt 11 to move the position of one or more screening meshes 12, thereby preventing the corn crumbs from falling into the same position and accumulating, affecting the screening effect.

[0046] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
