Description

Technical Field

[0001] The utility model relates to the field of feed production, and more specifically, to a screening device for feed production. Background Art

[0002] Feed is a general term for food for all animals raised by humans. More narrowly, feed refers primarily to food for animals raised in agriculture or animal husbandry. Feed includes more than ten types of raw materials, including soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils and fats, meat and bone meal, grains, and feed additives. After feed is produced, it needs to be screened to remove debris for secondary processing. A vibrating screen is typically used for feed screening. A vibrating screen is a high-precision fine powder screening machine with low noise, high efficiency, and a quick screen change time of 3-5 minutes. Its fully enclosed structure makes it suitable for screening and filtering materials such as grains, powders, and mucus.

[0003] Based on the above, the inventors found that when the existing screening device for feed production is used, since the feed is divided into dry material and wet material, the screen will become sticky after a long period of screening, thereby reducing the screening effect of the screening device and increasing the tedious steps of cleaning the screen. Therefore, in view of this, the existing structure is studied and improved to provide a screening device for feed production, in order to achieve the purpose of greater practical value. Utility Model Content

[0004] 1. Technical problems to be solved

The top of the upper cylinder is provided with a feeding port, and the outer walls of the lower cylinder and the upper cylinder are fixedly installed with a discharge pipe. The inner ring of the fixed plate is provided with a double-shaft motor, and the double-shaft motor is fixedly connected to the outer wall of the fixed plate through a support rod, the output end of the lower part of the double-shaft motor is connected to a heavy hammer through a coupling, and the output end of the upper part of the double-shaft motor is connected to a driving shaft through a coupling, one end of the driving shaft is fixedly installed with a fixing block, and a pair of limiting rods are fixedly installed on the outer wall of the fixed block, and one end of a pair of limiting rods is provided with a fixing plate, and a cleaning brush is fixedly installed on the top of the fixing plate.

[0009] Furthermore, the screen is sealed to the open opening of the lower cylinder, and one end of the cleaning brush is in contact with the bottom end of the screen.

[0010] Furthermore, a protective tube is fixedly installed at the bottom end of the inner wall of the lower tube. The protective tube is located at the center of the inner wall of the lower tube, and one end of the drive shaft passes through the lower tube through the through slot and extends to the inside of the protective tube.

[0011] Furthermore, a limiting groove is provided on the side where the pair of fixed plates are close to each other, one end of the limiting rod is inserted and installed inside the limiting groove, a return spring is provided inside the limiting groove, and a roller is fixedly installed on the side where the pair of fixed plates are away from each other.

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) This solution sets a fixed block, a fixed plate and a cleaning brush. After the device is put into use, the feed is poured into the interior of the upper cylinder through the feed inlet. At the same time, the feed falls on the screen. The double-axis motor drives the heavy hammer to vibrate the entire device, so that the feed is screened through the screen. At the same time, the double-axis motor will drive the drive shaft to rotate, and the drive shaft will drive the cleaning brush on the fixed plate to clean the bottom end of the screen, thereby effectively avoiding the phenomenon of feed sticking to the screen.

[0017] (2) In this solution, a reset spring, a roller and a protrusion are provided. When the driving shaft drives the fixed plate to rotate, the roller at one end of the fixed plate will roll on the inner wall of the lower cylinder. When the roller rolls to the outside of the protrusion on the inner wall of the lower cylinder, the fixed plate will be pushed to move through the protrusion of the protrusion. At the same time, the limit rod squeezes the reset spring inside the limit groove, thereby increasing the area of the screen cleaned by the cleaning brush through the reciprocating movement of the fixed plate.

The output end of the lower part of the motor 9 is connected to a heavy hammer through a coupling transmission, and the output end of the upper part of the dual-axis motor 9 is connected to a drive shaft 10 through a coupling transmission. A fixed block 12 is fixedly installed at one end of the drive shaft 10, and a pair of limit rods 13 are fixedly installed on the outer wall of the fixed block 12. A fixed plate 14 is provided at one end of the pair of limit rods 13, and a cleaning brush 15 is fixedly installed on the top of the fixed plate 14. This device can effectively prevent wet feed from causing the screen 5 to become sticky during screening, thereby greatly improving the effect of feed screening.

[0029] See Figure 2 、 3 , the screen 5 is blocked to the open part of the lower cylinder 4, and one end of the cleaning brush 15 is in contact with the bottom end of the screen 5; a protective cylinder 11 is fixedly installed at the bottom end of the inner wall of the lower cylinder 4, and the protective cylinder 11 is located at the center of the inner wall of the lower cylinder 4, and one end of the drive shaft 10 passes through the lower cylinder 4 through the through groove and extends to the inside of the protective cylinder 11. The protective cylinder 11 can effectively prevent the feed sieved out from the inside of the lower cylinder 4 from interfering with the drive shaft 10, and also prevent the feed from leaking from the through groove extending from the drive shaft 10 to the inside of the lower cylinder 4.

[0030] See Figure 3 、 4 , 5, 6, a pair of fixed plates 14 are provided with a limit groove 16 on the side close to each other, one end of the limit rod 13 is inserted into the interior of the limit groove 16, and a return spring 17 is provided inside the limit groove 16, and a pair of fixed plates 14 are fixedly installed with a roller 18 on the side away from each other; one end of the return spring 17 is fixedly connected to one end of the limit rod 13, and the other end of the return spring 17 is fixedly connected to one end of the inner wall of the limit groove 16; the outer wall of the roller 18 fits into the inner wall of the lower cylinder 4, and the inner wall of the lower cylinder 4 is evenly fixed with a protrusion 19, and the shape of the protrusion 19 is wavy. When the cleaning brush 15 above the fixed plate 14 cleans the bottom of the screen 5, the roller 18 at one end of the fixed plate 14 will roll on the inner wall of the lower cylinder 4, and when the roller 18 rolls onto the protrusion 19, the fixed plate 14 will be pushed by the protrusion 19, so that the cleaning brush 15 can be displaced back and forth, thereby increasing the area for cleaning the screen 5.

[0031] When in use: first, connect the device to an external power source, and drive the heavy hammer through the dual-axis motor 9 to make the device vibrate, then pour the feed into the interior of the upper cylinder 6 through the feed inlet 7, and at the same time, the feed falls on the screen 5, and the feed is screened by the screen 5. At the same time, the dual-axis motor 9 will drive the drive shaft 10 to rotate, and the drive shaft 10 will drive the cleaning brush 15 on the fixed plate 14 to clean the bottom end of the screen 5. When the cleaning brush 15 cleans the bottom end of the screen 5, the roller 18 at one end of the fixed plate 14 will be on the lower cylinder 4. The roller 18 rolls on the inner wall of the lower cylinder 4. When the roller 18 rolls to the outside of the protrusion 19 on the inner wall of the lower cylinder 4, the fixed plate 14 is moved by the protrusion of the protrusion 19. At the same time, the limiting rod 13 squeezes the return spring 17 inside the limiting groove 16. The reciprocating movement of the fixed plate 14 increases the area of the screen 5 cleaned by the cleaning brush 15. Then the feed screened by the screen 5 falls into the inside of the lower cylinder 4 and is then discharged through the discharge pipe 8 on the lower cylinder 4. At the same time, the feed on the screen 5 will be discharged through the discharge pipe 8 on the upper cylinder 6.
