Description

Technical Field

[0001] The invention relates to the technical field of biological feed processing, and in particular to a biological feed mixing and preparation device with a screening mechanism. Background Art

[0002] Trace element mixed feed, also known as trace element premix, is a uniform mixture of one or more trace mineral element compounds and a carrier or diluent in a certain proportion. When the mixed feed is mixed and dried, there will be residual moisture, which will cause the feed to clump, and then the large particles of the clump feed will not be able to pass through the sieve holes. In addition, due to the soft texture of some feeds, the sieve holes will be blocked during the screening process.

[0003] To this end, Chinese patent application CN117941774A discloses a biological feed mixing and drying integrated device and method containing Chinese herbal medicine, which is provided with a screening drum and a first motor. The first motor is started to drive the first rotating shaft to rotate, and the first rotating shaft can drive the screening drum to rotate. A plurality of crushing knives are fixedly installed on the first rotating shaft. When the powder and the agglomerated powder enter the screening drum, the agglomerated powder is continuously crushed by the crushing knives to become fine powder, and then the powder is screened out through the continuous rotation of the screening drum and collected through the discharge channel below. When the agglomerated powder is crushed, it can be continuously screened by the screening drum, thereby accelerating the processing and discharging process of the pesticide powder, and greatly improving the service life of the screening drum, and the practicality is strong.

[0004] Since the uniformity of feed directly affects the digestion, absorption and growth performance of animals, the mixing uniformity of feed is crucial. Traditional equipment mixes feed during the crushing process. However, since some feeds are clumped, the clumped feed can pass through the sieve holes after being broken up during the crushing process. After passing through the sieve holes, it is no longer affected by the rotation of the screening cylinder and cannot continue to be mixed, affecting the mixing uniformity of the feed. Once the mixing degree of the feed is poor, it will have a great impact on the subsequent feeding work. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention realizes the functions of crushing, screening and mixing biological feed through a frame and a mixing device. Through the arrangement of an outer barrel and an inner barrel, the screened feed can be fully mixed after the feed is crushed and screened, thereby ensuring the mixing uniformity of the feed, and solving the problem that the traditional mixing equipment cannot mix the screened feed. After the controller starts the rotary drive, the rotary drive drives the main shaft to rotate, and the main shaft drives the outer barrel and the inner barrel to rotate, and the rotary drive assembly is driven by the rotary torque provided by the rotation of the inner barrel, and the rotary drive assembly drives the rotating shaft to rotate, and the rotating shaft drives the crushing rod to rotate, and the agglomerated feed is crushed by the rotating crushing rod. After the size of the crushed feed is smaller than the fixed size of the sieve hole, as the inner barrel rotates, the feed passes through the sieve hole under the action of centrifugal force and gravity and falls into the outer barrel, and the feed continues to be mixed as the outer barrel rotates.

[0018] 2. The present invention realizes the function of controlling the rotation of the inner barrel by fixing the cover plate and the connecting ring. By setting the connecting ring, the axis of the inner barrel deviates from the axis of the outer barrel, and the outer barrel drives the connecting ring to rotate when rotating, so that the inner barrel as a whole performs a circular motion around the axis of the main shaft.

Since the first rotating gear is connected to the fixed cover plate, the first rotating gear will not rotate, and the first rotating gear is meshed with the second rotating gear. When the second rotating gear makes a circular motion around the axis of the first rotating gear, the second rotating gear will rotate along its axis, and then drive the rotating shaft to rotate through the second rotating gear, and the feed is crushed by the crushing rod on the rotating shaft.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1-Figure 4 A biological feed mixing and preparing device with a screening mechanism comprises a frame 1 and a mixing device 2; a main shaft 11 is rotatably arranged on the frame 1, and a processing barrel 12 for preparing feed is arranged on the frame 1, and the axis of the main shaft 11 is colinear with the axis of the processing barrel 12; the mixing device 2 comprises a rotary driver 21, an outer barrel 22, an inner barrel 23 and a rotary driving assembly 24; the rotary driver 21 is arranged on the frame 1, and the rotary driver 21 is used to drive the main shaft 11 to rotate; the outer barrel 22 is rotatably arranged in the processing barrel 12 , and the outer barrel 22 is coaxially connected to the main shaft 11; the inner barrel 23 is connected to the outer barrel 22, and the inner barrel 23 is located inside the outer barrel 22, a rotating shaft 231 is provided inside the inner barrel 23, a breaking rod 232 is provided on the rotating shaft 231, and a sieve hole 233 for feed to pass through is opened on the inner barrel 23; the rotary drive assembly 24 is transmission-connected with the rotating shaft 231; in the working state, when the rotary driver 21 drives the main shaft 11 to rotate, the main shaft 11 drives the outer barrel 22 to rotate, and the rotary drive assembly 24 drives the rotating shaft 231 to rotate.

[0033] The present invention realizes the functions of crushing, screening and mixing biological feed through the frame 1 and the mixing device 2. Through the setting of the outer barrel 22 and the inner barrel 23, the screened feed can be fully mixed after the feed is crushed and screened, thereby ensuring the mixing uniformity of the feed, solving the problem that traditional equipment cannot mix the screened feed. The frame 1 is provided with a controller for human-machine interaction, and the rotary driver 21 is preferably a servo motor, which is electrically connected to the controller; the inner barrel 23 and the outer barrel 22 are both provided with hatches for feeding. In the working state, the operator puts the feed to be processed into the inner barrel 23. Then, the controller starts the rotary driver 21. After receiving the signal, the rotary driver 21 drives the main shaft 11 to rotate. The main shaft 11 drives the outer barrel 22 and the inner barrel 23 to rotate, and the rotary torque provided by the rotation of the inner barrel 23 drives the rotary drive assembly 24. The rotary drive assembly 24 drives the rotating shaft 231 to rotate, and the rotating shaft 231 drives the breaking rod 232 to rotate. The agglomerated feed is broken by the rotating breaking rod 232. After the size of the broken feed is smaller than the fixed size of the sieve hole 233, as the inner barrel 23 rotates, the feed passes through the sieve hole 233 under the action of centrifugal force and gravity and falls into the outer barrel 22. As the outer barrel 22 rotates, the feed continues to be mixed. Through the separation effect of the inner barrel 23 and the outer barrel 22, the feed can be mixed while being screened to ensure the mixing uniformity of the feed, thereby ensuring the digestion, absorption and growth performance of the animal during use.

[0034] Reference Figure 3 and Figure 4 : A fixed cover plate 221 is rotatably provided on the side of the outer barrel 22 away from the rotating driver 21, and the fixed cover plate 221 is connected to the inner wall of the processing barrel 12; a connecting ring 222 is rotatably provided on the fixed cover plate 221, and the axis of the connecting ring 222 is colinear with the axis of the fixed cover plate 221, one end of the rotating shaft 231 close to the fixed cover plate 221 is rotatably connected to the connecting ring 222, and the end of the rotating shaft 231 away from the fixed cover plate 221 is connected to the inner wall of the outer barrel 22.

[0035] The present invention realizes the function of controlling the rotation of the inner barrel 23 by fixing the cover plate 221 and the connecting ring 222. By setting the connecting ring 222, the axis of the inner barrel 23 deviates from the axis of the outer barrel 22, and the outer barrel 22 drives the connecting ring 222 to rotate when rotating, so that the inner barrel 23 as a whole performs a circular motion around the axis of the main shaft 11. While the feed is crushed by the crushing rod 232, the position of the inner barrel 23 can be periodically changed, so that the feed of qualified size can be dispersed at different positions when passing through the sieve hole 233, further improving the mixing efficiency and mixing uniformity of the feed in the outer barrel 22.

[0036] Reference Figure 4 and Figure 5A connecting shaft 223 is provided on the fixed cover plate 221 , and the connecting shaft 223 is rotatably connected to the outer wall of the inner barrel 23 , and the axis of the connecting shaft 223 is colinear with the axis of the fixed cover plate 221 .

[0037] The present invention limits the rotation of the inner barrel 23 around the rotating shaft 231 by setting the connecting shaft 223, thereby facilitating the operator to control the stability of the inner barrel 23. When the connecting shaft 223 is not used for connection, after the rotary driver 21 stops driving, the inner barrel 23 will rotate freely around the rotating shaft 231 under the action of inertia. When the operator is loading, he needs to wait for the inner barrel 23 to stop rotating, and needs to rotate the inner barrel 23 to find the hatch position of the inner barrel 23. For this purpose, the connecting shaft 223 is set on the fixed cover plate 221, and the connecting shaft 223 deviating from the axis of the inner barrel 23 is connected to the fixed cover plate 221 to limit the rotation of the inner barrel 23 around the rotating shaft 231, and because the axis of the connecting shaft 223 is aligned with the fixed cover plate 221, the inner barrel 23 is limited to rotate around the rotating shaft 231. The axes of the outer barrel 22 and the inner barrel 23 are colinear. When the rotary driver 21 drives the outer barrel 22 to rotate, the outer barrel 22 drives the inner barrel 23 to rotate synchronously through the connecting ring 222. The connecting shaft 223 and the inner barrel 23 rotate relative to each other, which is equivalent to the inner barrel 23 rotating around the axis of the connecting shaft 223. The rotation of the outer barrel 22 and the connecting ring 222 can also shake the feed inside the inner barrel 23 to a greater extent. The shaking action can disperse the feed, so that the feed can fully contact with the rotating breaking rod 232 to break up the feed, further avoiding the situation where the feed accumulates and blocks the sieve hole 233.

[0038] Reference Figure 4 and Figure 6 : The rotation driving assembly 24 includes a first rotating gear 241 and a second rotating gear 242; the first rotating gear 241 is sleeved on the connecting shaft 223, and the first rotating gear 241 is connected to the fixed cover plate 221; the second rotating gear 242 is fixedly sleeved on the rotating shaft 231, and the second rotating gear 242 is meshed and connected with the first rotating gear 241.

[0039] The present invention realizes the function of controlling the rotation of the rotating shaft 231 while the connecting ring 222 rotates through the first rotating gear 241 and the second rotating gear 242. After the rotating driver 21 is started, the rotating driver 21 drives the main shaft 11 and the outer barrel 22 to rotate, the outer barrel 22 drives the connecting ring 222 to rotate, and the connecting ring 222 drives the rotating shaft 231 and the inner barrel 23 to rotate around the connecting shaft 223. Since the first rotating gear 241 is connected to the fixed cover plate 221, the first rotating gear 241 will not rotate, and the first rotating gear 241 is meshed and connected with the second rotating gear 242. When the second rotating gear 242 makes a circular motion around the axis of the first rotating gear 241, the second rotating gear 242 will rotate along its axis, and then drive the rotating shaft 231 to rotate through the second rotating gear 242, and the feed is broken by the crushing rod 232 on the rotating shaft 231.

[0040] Reference Figure 4-Figure 6 : The frame 1 is provided with an auxiliary control mechanism 3 for adjusting the screening aperture of the inner barrel 23, and the auxiliary control mechanism 3 includes an inner lining layer 31 and a telescopic control component 32; the inner lining layer 31 is slidably matched with the inner barrel 23, and a through hole is provided on the inner lining layer 31, and the inner lining layer 31 is rotatably connected with the rotating shaft 231; the rotating shaft 231 is slidably matched with the inner barrel 23, and the telescopic control component 32 is used to control the movement of the inner barrel 23 along the axial direction of the rotating shaft 231; in the working state, the overlapping part of the through hole on the inner lining layer 31 with respect to the screening aperture 233 of the inner barrel 23 constitutes a channel for feed to pass through.

[0041] The present invention realizes the function of adjusting the effective aperture of the sieve hole 233 on the inner barrel 23 through the inner lining layer 31 and the telescopic control component 32. When screening feed, different feeds require different size standards. For this reason, it is usually necessary to replace screening components with different apertures, which is not only too cumbersome to disassemble and assemble, but also has a great impact on work efficiency. For this reason, an auxiliary control mechanism 3 for adjusting the screening aperture of the inner barrel 23 is designed. When adjusting, the operator controls the movement of the inner barrel 23 through the telescopic control component 32. As the inner barrel 23 moves, the overlapping area of ​​the through hole on the inner lining layer 31 and the sieve hole 233 changes. When the area of ​​the shielding part of the inner lining layer 31 on the sieve hole 233 increases, the overlapping area of ​​the through hole and the sieve hole 233 decreases, resulting in a decrease in the effective screening area of ​​the sieve hole 233. By adjusting the position of the inner barrel 23, the effective screening aperture of the sieve hole 233 on the inner barrel 23 can be conveniently adjusted.

[0042] Reference Figure 1 , Figure 7-Figure 9 : A vibration mechanism 4 is provided on the processing barrel 12, and the vibration mechanism 4 includes a mounting seat 41, a movable seat 42 and a movement control component 43; circular side panels are provided on both sides of the processing barrel 12, and the mounting seat 41 is installed on the side panels of the processing barrel 12, and the mounting seat 41 abuts against the connecting shaft 223; at least three arc-shaped protrusions 411 are provided on the mounting seat 41, and the multiple arc-shaped protrusions 411 are equidistantly arranged along a straight line; a movable block 421 for colliding with the arc-shaped protrusion 411 is provided on the movable seat 42; the movement control component 43 is used to control the movement of the movable seat 42.

[0043] The present invention realizes the function of providing vibration effect to the inner barrel 23 through the mounting seat 41, the movable seat 42 and the moving control assembly 43. During the working process, although the inner barrel 23 can be continuously shaken by the driving of the rotary driver 21, some feed will still block the sieve hole 233 after long-term working. For this reason, a vibration mechanism 4 is designed, and the movable seat 42 is controlled by the moving control assembly 43 to move along the surface of the mounting seat 41, and then the movable block 421 on the movable seat 42 sequentially contacts with the multiple arc-shaped protrusions 411 on the mounting seat 41 according to the moving direction, so that the movable block 421 collides with the arc-shaped protrusions 411, and the generated vibration is transmitted to the connecting shaft 223 through the mounting seat 41, and then transmitted to the inner barrel 23 through the connecting shaft 223.

[0044] Reference Figure 2 and Figure 7 : The telescopic control assembly 32 includes a mounting plate 321 and a linear driver 322; the mounting plate 321 is arranged on the side plate of the processing barrel 12; the linear driver 322 is mounted on the mounting plate 321; the connecting shaft 223 is slidably matched with the fixed cover plate 221 and the side plate of the processing barrel 12, and the linear driver 322 is used to drive the connecting shaft 223 to slide;

[0045] The present invention realizes the function of driving the connecting shaft 223 and the inner barrel 23 to move through the mounting plate 321 and the linear driver 322. The linear driver 322 is preferably a linear cylinder or a hydraulic cylinder, and the linear driver 322 is electrically connected to the controller; when adjusting the effective aperture of the sieve hole 233, the operator sends a signal to the linear driver 322 through the controller, and the linear driver 322 controls the movement of the connecting shaft 223 after receiving the signal, and the connecting shaft 223 drives the inner barrel 23 connected thereto to move. As the inner barrel 23 moves, the overlap area of ​​the through hole on the inner lining layer 31 and the sieve hole 233 changes. When the area of ​​the shielding part of the inner lining layer 31 on the sieve hole 233 increases, the overlap area of ​​the through hole and the sieve hole 233 decreases, resulting in a decrease in the effective screening area of ​​the sieve hole 233, and adjusting the effective screening aperture of the sieve hole 233 on the inner barrel 23.

[0046] Reference Figure 7-Figure 9 : The moving control component 43 includes a guide rail 431 and an elastic member 432; the guide rail 431 is arranged on the mounting seat 41, and the movable seat 42 is slidably installed on the guide rail 431; the two ends of the elastic member 432 are respectively connected to the movable block 421 and the movable seat 42; a transmission component 44 is provided on the side panel of the processing barrel 12, and the linear drive 322 is connected to the movable seat 42 through the transmission component 44.

[0047] The present invention realizes the function of guiding the movable block 421 to stably collide with the arc-shaped protrusion 411 through the guide rail 431 and the elastic member 432. During operation, when the linear driver 322 drives the connecting shaft 223 to move, the linear driver 322 controls the movable seat 42 to move along the guide rail 431 through the transmission assembly 44. When the movable block 421 contacts the arc-shaped protrusion 411, it is squeezed by the arc surface of the arc-shaped protrusion 411, and the elastic member 432 contracts under the squeezing action. When the movable block 421 separates from the movable seat 42, the movable block 421 collides with the mounting seat 41 under the elastic force of the elastic member 432, and then vibrates and transmits to the inner barrel 23.

[0048] Reference Figure 7-Figure 9 : The transmission assembly 44 includes a support 441 and a connecting rod 442; the support 441 is slidably mounted on the mounting plate 321, and the support 441 is connected to the connecting shaft 223, and the driving end of the linear drive 322 is connected to the support 441; the two ends of the connecting rod 442 are respectively hinged to the support 441 and the movable seat 42.

[0049] The present invention realizes the function of controlling the movement of the inner barrel 23 through the linear driver 322 through the support 441 and the connecting rod 442. When the linear driver 322 is started, the linear driver 322 drives the support 441 to move, and when the support 441 drives the connecting shaft 223 to move, the support 441 pulls or pushes the connecting rod 442 at the same time. After being subjected to force, the connecting rod 442 controls the movable seat 42 to move along the guide rail 431, and then provides vibration through the periodic collision between the movable block 421 and the arc-shaped protrusion 411. As the effective aperture of the sieve hole 233 is reduced, the feed that could originally pass through the sieve hole 233 smoothly will be stuck at the sieve hole 233. For this reason, the linear drive 322 is used to control the movement of the movable seat 42, which can provide vibration to the inner barrel 23 when the effective aperture of the sieve hole 233 is adjusted, so as to shake the feed at the sieve hole 233 down and separate the feed from the sieve hole 233, thereby avoiding the situation where the feed is stuck at the sieve hole 233 when the effective aperture of the sieve hole 233 is reduced.

[0050] Reference Figure 1 and Fig.10 : A Hall sensor 13 is provided on the inner wall of the outer barrel 22, and a positioning block 14 cooperating with the Hall sensor 13 is provided on the outer wall of the inner lining layer 31.

[0051] The present invention realizes the function of accurately locating the position of the inner barrel 23 through the Hall sensor 13 and the positioning block 14. The positioning block 14 is preferably a permanent magnet. The Hall sensor 13 is electrically connected to the controller; when controlling the reset of the inner barrel 23, the outer barrel 22 and the inner barrel 23 are driven to rotate by the rotary driver 21, and the inner barrel 23 drives the inner lining 31 to rotate synchronously. When the Hall sensor 13 is aligned with the positioning block 14 on the inner lining 31, the Hall sensor 13 feeds back a signal to the controller, and the controller stops driving the rotary driver 21, thereby ensuring the reset accuracy of the inner barrel 23. Avoid the situation where the hatch of the inner barrel 23 and the hatch of the outer barrel 22 are misaligned and affect the loading of materials.

[0052] Working principle: In the working state, the operator puts the feed to be processed into the inner barrel 23. Then the controller starts the rotary driver 21. After receiving the signal, the rotary driver 21 drives the main shaft 11 to rotate, and the main shaft 11 drives the outer barrel 22 and the inner barrel 23 to rotate, and the rotary drive assembly 24 is driven by the rotary torque provided by the rotation of the inner barrel 23. The rotary drive assembly 24 drives the rotating shaft 231 to rotate, and the rotating shaft 231 drives the crushing rod 232 to rotate. The agglomerated feed is broken by the rotating crushing rod 232. After the size of the broken feed is smaller than the fixed size of the sieve hole 233, as the inner barrel 23 rotates, the feed passes through the sieve hole 233 under the action of centrifugal force and gravity and falls into the outer barrel 22, and the feed continues to be mixed as the outer barrel 22 rotates. Through the separation effect of the inner barrel 23 and the outer barrel 22, the feed can be screened and mixed at the same time, ensuring the mixing uniformity of the feed, and then the digestion, absorption and growth performance of the animal can be guaranteed when in use.

It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
