Description

Technical Field

[0001] The invention relates to the technical field of feed production, and in particular to a rotary feed production and sorting device used in animal husbandry. Background Art

[0002] In animal husbandry, the quality of feed is crucial to the growth and development of livestock. However, existing feed often contains feed with uneven particle sizes, which not only affects livestock's feeding and digestion, but may also have adverse effects on livestock's health. Therefore, it is necessary to sort them according to size for different livestock.

[0003] During the feed production process, feed particles need to be classified according to size. Existing screening devices are roughly divided into two types: flat vibrating screens and drum screens. Regardless of the type of screening equipment, there is a problem of reduced screening efficiency due to the blockage of the screen holes. The screen holes are not blocked by feed particles, but after long-term operation, feed powder will be compacted at the screen holes, causing the screen holes to become smaller and smaller, causing blockage. In order to restore the screening efficiency, it is necessary to stop the machine to clean the screen holes. However, the process of stopping the equipment to clean the equipment will affect the screening progress;

[0004] In addition, since the feed pellets need to be cooled for a period of time after pelleting, they are not sorted immediately. There are also situations where the feed pellets do not need to be sorted and bagged immediately, but are stored. During the storage process, a certain amount of dust will accumulate in the feed. When the existing sorting equipment screens these particles, dust will be raised, polluting the workshop environment.

[0034] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0035] A rotary feed production and sorting device for animal husbandry, as shown in the attached Figure 1-10 As shown, it includes a frame 1, on which an inclined polygonal roller 5 is rotatably connected, and a discharge port 6 is provided at one end of the polygonal roller 5 that is inclined downward. The inclination angle of the polygonal roller 5 is not greater than ten degrees, and can be adjusted according to the actual situation on site, so as to ensure the screening effect and take into account the screening efficiency, avoid too large an inclination angle, and small particles of feed roll out from the discharge port 6 before the screening is completed, and avoid too small an inclination angle, which leads to a situation where the discharging speed is too slow. By tilting the polygonal roller 5 and the sieve plate 39, the sorted feed can roll obliquely downward for collection, thereby realizing continuous screening operation. A plurality of sieve plates 39 that can slide radially along the polygonal roller 5 are provided on the circumferential surface of the polygonal roller 5. The polygonal roller 5 and all the sieve plates 39 can cooperate to form a screening cylinder for screening feed, and feed particles larger than the mesh of the sieve plate 39 can only be separated from the polygonal roller 5 through the discharge port 6;

[0036] There is an angle between two adjacent sieve plates 39, so when the polygonal drum 5 rotates, it cooperates with the sieve plates 39 to lift the feed, thereby increasing the tumbling degree of the feed in the polygonal drum 5 and improving the screening efficiency. At the same time, it can increase the force of the feed hitting the sieve plates 39, so that the sticky feed particles are scattered;

[0037] The surface of the polygonal drum 5 is provided with a dust removal component 2, which is used to cooperate with the polygonal drum 5 to remove dust mixed in the feed. The polygonal drum 5 is provided with a vibration component 3, which can simultaneously vibrate all the sieve plates 39 when the polygonal drum 5 rotates in cooperation with the vibration component 3. The frame 1 is provided with a driving component 4, which is used to simultaneously drive the dust removal component 2 and the polygonal drum 5. During the screening process, the dust mixed in the feed can be raised, and the dust can be gathered by the dust removal component 2 and transported to a designated location to avoid dust in the workshop.

[0038] The problem of sieve hole blockage can be solved by setting the vibration component 3. During the rotation of the polygonal drum 5, the vibration component 3 can cooperate with the sieve plate 39 to vibrate along the radial direction of the polygonal drum 5, and this vibration is caused by the collision between the sieve plate 39 and the fixed frame 36. Therefore, it can not only further improve the efficiency of screening feed, but more importantly, it can prevent feed powder from accumulating and compacting in the sieve holes of the sieve plate 39, thereby ensuring the continuous unobstructedness of the sieve holes, thereby omitting the step of stopping the machine to clean the sieve plate 39, so that the screening operation can be carried out continuously, thereby improving the screening efficiency.

[0039] As attached Figure 5 , 6 As shown in Figures 9, each side of the polygonal drum 5 is provided with a mounting opening, and the sieve plate 39 is slidably arranged in the mounting opening, and the side of the sieve plate 39 is gap-matched with the inner wall of the mounting opening. The mesh holes on the sieve plate 39 are circular and distributed on the sieve plate 39 in a rectangular array.

A rotating shaft 2 30 is rotatably arranged in the polygonal drum 5, and the rotating shaft 2 30 is coaxial with the polygonal drum 5. Both ends of the rotating shaft 2 30 pass through the polygonal drum 5 respectively, and one end of the rotating shaft 2 30 penetrates into the air inlet hopper 19 through the connecting pipe 18. A bearing seat 2 32 is fixedly arranged in the air inlet hopper 19, and the bearing seat 2 32 is rotatably connected with the rotating shaft 2 30. A wind wheel 2 31 is arranged in the air inlet hopper 19 for sucking external air into the polygonal drum 5. The wind wheel 2 31 is fixedly arranged on the rotating shaft 2 30. A filter net 29 is arranged in the air guide cover 22. A feeding hopper 21 is fixedly arranged on the air inlet hopper 19, and the feeding hopper 21 is located between the wind wheel 2 31 and the connecting pipe 18. A filter net 20 is arranged at the end of the air inlet hopper 19 for preventing external garbage from entering the air inlet hopper 19. The top of the air guide cover 22 is connected with a pipeline 23.

[0041] The wind wheel 2 31 draws external air into the polygonal drum 5, and the wind wheel 1 28 can draw the dust and air in the polygonal drum 5 into the air guide cover 22. The pipe 23 can be connected to the outside of the workshop, or a dust removal bag can be tied at the end of the pipe 23 to collect dust, thereby avoiding dust in the workshop.

[0042] As attached Figure 2 , 5 As shown, the driving assembly 4 includes a fixed shaft 8, which is fixed at the end of the polygonal roller 5, and the fixed shaft 8 is coaxial with the polygonal roller 5. A hole is opened in the center of the fixed shaft 8, and the rotating shaft 2 30 passes through the hole. A motor 12 and a reduction gear box 11 are fixed on the frame 1, and the output shaft of the motor 12 is connected to the input shaft of the reduction gear box 11. The output shaft of the reduction gear box 11 is fixed with a driving gear 10, and a driven gear 9 is fixed on the fixed shaft 8, and the driving gear 10 is meshed with the driven gear 9. A sprocket 13 is fixed on the rotating shaft 1 24 and the rotating shaft 2 30, and the two sprockets 13 are connected by a chain 14. A sprocket 2 15 is fixed on the output shaft of the motor 12 and the rotating shaft 2 30, and the two sprockets 15 are connected by a chain 2 16.

[0043] The driving assembly 4 can amplify the speed ratio of the wind wheel 1 28, the wind wheel 2 31 and the polygonal drum 5 through the cooperation of the reduction gear box 11, the driving gear 10 and the driven gear 9. The speed of the wind wheel 1 28 and the wind wheel 2 31 is greater than that of the polygonal drum 5.

[0044] The reduction gearbox 11 is driven by the motor 12, and the reduction gearbox 11 can rotate the fixed shaft 8 and the polygonal roller 5 through the driving gear 10 and the driven gear 9. The motor 12 can rotate the rotating shaft 2 30 and the rotating shaft 1 24 through the sprocket 1 13, the chain 1 14, the sprocket 2 15 and the chain 2 16.

[0045] As attached Figure 5 , 6 As shown, the vibration assembly 3 includes two fixed frames 36, which are respectively fixed on both sides of the surface of the polygonal drum 5, the surface of the sieve plate 39 is in contact with the inner wall of the fixed frame 36, and tension springs 38 are arranged at the four corners of the sieve plate 39 for pulling the sieve plate 39 to make it close to the fixed frame 36. The end of the tension spring 38 away from the sieve plate 39 is fixed to the fixed frame 36 through a fixing seat 37, and circular covers 34 are fixed at both ends of the polygonal drum 5, and movable plates 35 are fixed on both sides of the sieve plate 39, and the length direction of the movable plates 35 is arranged radially along the polygonal drum 5, the movable plates 35 pass through the circular covers 34, and the part of the movable plates 35 passing through the surface of the circular covers 34 is arc-shaped, and pulleys 33 are fixed on both sides of the shell 17, and the two pulleys 33 are respectively in contact with the surfaces of the two circular covers 34, and the two pulleys 33 correspond to the movable plates 35 arranged on both sides of the sieve plate 39;

[0046] The movable plate 35 rotates with the polygonal drum 5. When the movable plate 35 passes through the pulley 33, the movable plate 35 is blocked by the pulley 33 and will drive the screen plate 39 to move into the polygonal drum 5. After the movable plate 35 passes through the pulley 33, it will be driven by the tension spring 38 to move out of the polygonal drum 5 and hit the fixed frame 36 to generate vibration. It should be noted that the screen plate 39 will not separate from the inner wall of the installation port of the polygonal drum 5 during the reciprocating movement, so the screen plate 39 will not have a gap with the installation port to cause feed leakage.

[0047] As attached Figure 1-4 As shown, both sides of the shell 17 are in contact with the opposite surfaces of the two circular covers 34 respectively. This arrangement can improve the dust collection efficiency of the dust removal component 2.

[0048] As attached Figure 1 , 2As shown in FIGS. 9 and 10, a downwardly inclined guide groove 7 is provided on the shell 17 for transferring feed. The bottom of the inner wall of the shell 17 is inclined downward, and an opening for the feed to roll down is provided on the side of the shell 17. Small particles of feed can pass through the screen plate 39 and gather in the shell 17, and finally roll out from the opening along the bottom of the inner wall of the shell 17, while large particles of feed will roll down into the guide groove 7 along the inclined screen plate 39 and thus the discharge port 6, which makes it easy to collect the feed.

[0049] As attached Figure 6 As shown, a stirring blade 40 is fixed on the second rotating shaft 30 , and the stirring blade 40 rotates along with the second rotating shaft 30 . By providing the stirring blade 40 , the tumbling efficiency of the feed can be further improved, and the screening effect can be improved.

[0050] Working principle:

[0051] The equipment to be sorted is continuously fed into the polygonal drum 5 through the conveying device, and the polygonal drum 5 and the wind wheel 1 28 and the wind wheel 2 31 of the dust removal component 2 are rotated by the driving component 4. During the rotation of the polygonal drum 5 and the screen plate 39, the feed can roll in the polygonal drum 5, and because there is an angle between two adjacent screen plates 39, the polygonal drum 5 can cooperate with the screen plate 39 to lift the feed when rotating, thereby increasing the rolling degree of the feed in the polygonal drum 5 and the screening efficiency, and at the same time, it can increase the force of the feed hitting the screen plate 39 to disperse the sticky feed particles;

[0052] By tilting the polygonal drum 5 and the screen plate 39, the sorted feed can roll down obliquely for collection, thus achieving continuous screening operation;

[0053] During the screening process, dust mixed in the feed can be raised, and the dust removal component 2 can gather the dust and transport it to a designated location to avoid dust in the workshop;

[0054] During the rotation of the polygonal drum 5, the vibration component 3 can cooperate with the screen plate 39 to vibrate along the radial direction of the polygonal drum 5, and this vibration is caused by the collision between the screen plate 39 and the fixed frame 36. Therefore, it can not only further improve the efficiency of screening feed, but more importantly, it can prevent feed powder from accumulating and compacting in the screen holes of the screen plate 39, thereby ensuring the continuous unobstructedness of the screen holes, thereby omitting the step of stopping the machine to clean the screen plate 39, so that the screening operation can be carried out continuously, and the screening efficiency is improved.
