Description

Technical Field

[0001] The invention relates to the technical field of livestock feed cutting and screening, in particular to a feed screening and collecting device for livestock feed processing and a screening method thereof. Background Art

[0002] Livestock feed refers to feed used for the production of cattle, pigs, sheep and other livestock. It has a wide variety and uses. During the livestock feed processing, workers need to cut and crush the livestock feed first, and then use a sieve plate to screen the cut livestock feed so that the size of the screened feed meets the standards for livestock consumption;

[0003] When using a screening and collecting device to screen livestock feed, the screen plate will screen out feed that does not meet the specifications. At this time, the staff needs to put the feed back into the grinder for grinding and screening the feed that does not meet the specifications again. This will not only increase the workload and processing time and reduce the overall production efficiency, especially in large-scale production. This repetitive operation will affect the smoothness and production capacity of the production line. In addition, before the staff removes the feed that does not meet the specifications above the screen plate, the feed accumulates above the screen plate, which increases the load on the screen plate and causes the screen plate to wear more. In the long run, the life of the screen plate will be shortened and it will need to be replaced more frequently, increasing production costs and maintenance difficulties.

[0004] Therefore, the present invention proposes a feed screening and collecting device and a screening method for livestock feed processing to solve the above problems. Summary of the invention

[0023] (III) Beneficial effects

[0024] Compared with the prior art, the present invention provides a feed screening and collecting device for livestock feed processing and a screening method thereof, which has the following beneficial effects:

[0025] 1. The irregular feed secondary crushing mechanism can drive the first crushing cone and the second crushing cone on both sides to approach each other during the reciprocating screening of the vibrating screen plate, and perform secondary extrusion and crushing on the feed remaining on the vibrating screen plate. This not only avoids the repeated operation of re-putting the feed into the grinder for crushing, reduces the workload and processing time, and significantly improves the overall production efficiency, but also performs secondary processing on the residual feed in real time during the screening process, reduces the accumulation of feed on the screen plate, thereby improving the continuity and efficiency of screening, and because the accumulation of feed on the vibrating screen plate is reduced, the load of the vibrating screen plate is also reduced, thereby reducing the wear of the vibrating screen plate, so that the life of the vibrating screen plate is effectively extended.

[0026] 2. By setting up the feed collecting and flattening mechanism, when using the collecting box to collect the screened feed, the spreading plate can be driven to reciprocate horizontally above the collecting box to evenly spread the feed in the collecting box. This not only helps to save space in the collecting box and ensure that the stacking density of the feed is moderate, which is convenient for subsequent storage, transportation and use, but also avoids excessive local accumulation of feed inside the collecting box, which affects the subsequent staff from taking the collecting box out of the screening room, thereby facilitating the staff to smoothly take out the collecting box and pack the screened feed.

[0027] 3. By setting the corrugated groove and sliding column, the beating plate can be driven to beat the bottom of the vibrating screen plate up and down in the process of driving the horizontal reciprocating motion of the spreading plate. This can not only effectively reduce the blockage of the vibrating screen plate, keep the screen holes unobstructed, and ensure the continuity and stability of the screening process, but also the vibration of the beating plate can directly act on the feed particles on the vibrating screen plate, making them looser, which is convenient for improving the fluidity of the feed and making it easier for the feed particles to pass through the screen holes, thereby increasing the screening speed.

[0042] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] A feed screening and collecting device for livestock feed processing in this embodiment, such as Figure 1 - Fig. 9 As shown, it includes a crushing chamber 1, a screening chamber 2 is fixedly connected to the lower end of the crushing chamber 1, a feeding port 3 is provided at the upper end of the crushing chamber 1, a vibrating screen plate 8 is slidably connected to the inside of the screening chamber 2, corrugated grooves 9 are symmetrically provided inside the screening chamber 2, a collecting box 5 is slidably connected to the lower end of the screening chamber 2, a visual window 4 is provided on the side of the screening chamber 2 close to the collecting box 5, and a feed secondary crushing mechanism is provided above the vibrating screen plate 8, and the feed secondary crushing mechanism is used for secondary crushing of non-standard feed accumulated above the vibrating screen plate 8.

[0044] In this embodiment, Figure 2 and Figure 4 As shown, the feed secondary crushing mechanism includes a symmetrically arranged first movable plate 601 and a second movable plate 605, which are both horizontally slidably connected to the inside of the screening chamber 2, and the first movable plate 601 and the second movable plate 605 are fixedly connected to the first crushing cone 602 on the opposite sides of the first movable plate 601 and the second movable plate 605, and the second crushing cone 606 is fixedly connected to the opposite side between the two second movable plates 605. When the first movable plate 601 and the second movable plate 605 slide close to each other, the first crushing cone 602 and the second crushing cone 606 will be pushed to extrude and crush the feed.

[0045] In this embodiment, Figure 3 As shown, the upper end surfaces of the first movable plate 601 and the second movable plate 605 are symmetrically connected to the connecting plates 604 for rotation, and the lifting plates 603 are rotationally connected between the connecting plates 604 on the same side. The lifting plates 603 are vertically slidably connected to the inner wall of the screening chamber 2. When the lifting plates 603 are raised and lowered, the first movable plate 601 and the second movable plate 605 can be pulled closer to or away from each other by rotating the connected connecting plates 604.

[0046] In this embodiment, Figure 5As shown, the lower ends of the lifting plates 603 are fixedly connected with connecting columns 607, and the connecting columns 607 are all slidably connected to the screening chamber 2. The lower ends of the connecting columns 607 are fixedly connected with lifting blocks 608, and the lifting blocks 608 are fixedly connected to the side walls of the vibrating screen plate 8. By setting the connecting columns 607 and the lifting blocks 608, the lifting plate 603 and the vibrating screen plate 8 can be connected, and the reciprocating shaking of the vibrating screen plate 8 can be converted into driving the lifting plate 603 to perform reciprocating lifting and lowering, thereby reducing energy consumption.

[0047] In the prior art, when the feed that does not meet the specifications is screened out, the staff needs to put the feed back into the grinder to grind and screen the feed that does not meet the specifications again, which not only increases the workload and processing time, but also reduces the overall production efficiency. Especially in large-scale production, this repetitive operation will affect the smoothness and production capacity of the production line. In addition, before the staff removes the feed that does not meet the specifications above the screen plate, the feed accumulates on the screen plate, which increases the load on the screen plate and causes the screen plate to wear more. In the long run, the life of the screen plate will be shortened and it needs to be replaced more frequently, which increases the production cost and maintenance difficulty. Compared with the prior art, the vibrating screen plate 8 can be moved up and down. During the reciprocating screening process, the first crushing cone 602 and the second crushing cone 606 on both sides are driven to approach each other, and the feed remaining on the vibrating screen plate is squeezed and crushed for the second time. This not only avoids the repeated operation of putting the feed back into the grinder for crushing, reduces the workload and processing time, and significantly improves the overall production efficiency, but also immediately performs secondary processing on the residual feed during the screening process, reduces the accumulation of feed on the screen plate, thereby improving the continuity and efficiency of screening, and since the accumulation of feed on the vibrating screen plate 8 is reduced, the load of the vibrating screen plate 8 is also reduced, thereby reducing the wear of the vibrating screen plate 8, and the life of the vibrating screen plate 8 is effectively extended.

[0048] In other aspects, this embodiment also provides a feed collecting and flattening mechanism for flattening the screened feed in the collecting box 5, such as Figure 2 , Figure 6 - Figure 8 As shown, the feed collecting and flattening mechanism includes a driving motor 701, which is fixedly connected to the side wall of the screening chamber 2. The output end of the driving motor 701 is fixedly connected to a reciprocating screw 702, which penetrates and is rotatably connected to the screening chamber 2. A linkage plate 706 is threadedly connected to the reciprocating screw 702, and the lower end surfaces of the linkage plates 706 are fixedly connected to a spreading plate 703. The spreading plate 703 is horizontally slidably connected to the inside of the screening chamber 2, and the spreading plate 703 is located above the collecting box 5.

[0049] In this embodiment, Figure 7As shown, an extension plate 707 is slidably connected to the top of the linkage plate 706, and a slapping plate 704 is fixedly connected to the upper end surface of the extension plate 707. The slapping plate 704 is attached to the lower end surface of the vibrating screen plate 8. When the slapping plate 704 moves up and down, it can drive the extension plate 707 to slide synchronously in the linkage plate 706, thereby maintaining the connection between the slapping plate 704 and the linkage plate 706.

[0050] In this embodiment, Figure 8 As shown, sliding columns 705 are fixedly connected on both sides of the flapping plate 704, and the sliding columns 705 are slidably connected in the corrugated groove 9. The sliding columns 705 are limited by the corrugated groove 9, so that when the flapping plate 704 moves horizontally back and forth, the flapping plate 704 can reciprocate up and down synchronously.

[0051] Compared with the prior art, when the collecting box 5 is used to collect the screened feed, the spreading plate 703 can be driven to reciprocate horizontally above the collecting box 5 to evenly spread the feed in the collecting box 5, which not only helps to save space in the collecting box 5 and ensures that the stacking density of the feed is moderate, which is convenient for subsequent storage, transportation and use, but also avoids the situation where the feed in the collecting box 5 is locally stacked too high, which affects the subsequent staff to take out the collecting box 5 from the screening chamber 2, so that the staff can smoothly take out the collecting box 5 to pack the screened feed;

[0052] Secondly, by setting the corrugated groove 9 and the sliding column 705, the beating plate 704 can be driven to beat the bottom of the vibrating screen plate 8 up and down while driving the spreading plate 703 to move back and forth horizontally. This can not only effectively reduce the blockage of the vibrating screen plate 8, keep the screen holes unobstructed, and ensure the continuity and stability of the screening process, but also the vibration of the beating plate 704 can directly act on the feed particles on the vibrating screen plate 8, making them looser, thereby improving the fluidity of the feed and making it easier for the feed particles to pass through the screen holes, thereby increasing the screening speed.

[0053] In other aspects, this embodiment also provides a feed screening method for livestock feed processing, such as Figure 1 - Fig. 9 As shown, the following steps are included;

[0054] Step 1: Prepare the feed to be processed and use a drum sieve or similar equipment to clean the feed to remove large impurities such as stones, dirt and metal pieces;

[0055] Step 2: Cut and crush the processed feed, and put the cut and crushed feed into a screening and collecting device for screening;

[0056] Step 3: Use a collecting device to collect the feed screened by the sieve plate and perform subsequent processing or packaging;

[0057] Step 4: While the screen plate is moving up and down, use the secondary feed crushing mechanism to crush the feed that does not meet the specifications above the screen plate again.

[0058] In this embodiment, before collecting the screened feed in step 3, a portion of the feed is taken out as a sample for testing.

[0059] In this embodiment, before cutting, crushing and screening the feed in step 2, appropriate crushing and screening equipment is selected according to the type of feed, particle size requirements and production scale.

[0060] The working process and principle involved in the overall content of the above embodiment are as follows:

[0061] After the staff puts the feed into the crushing chamber 1 through the feeding port 3 and uses the existing rotating blade cutting and crushing mechanism in the crushing chamber 1 to cut and crush the feed, the cut and crushed feed will fall onto the top of the vibrating screen plate 8 inside the screening chamber 2. At this time, the existing vibration motor is used to drive the vibrating screen plate 8 to reciprocate up and down inside the screening chamber 2 to screen the feed. During the reciprocating up and down movement of the vibrating screen plate 8, the lifting blocks 608 connected on both sides can be used to drive the connecting column 607 to slide up and down synchronously in the screening chamber 2, and push the lifting plate 603 connected to the upper end of the connecting column 607 to reciprocate on the inner wall of the screening chamber 2. As the lifting plate 603 reciprocates, the lifting plate 603 can pull one end of the connecting plate 604 connected to the rotation on both sides to move up and down synchronously, and reciprocately change the inclination angle of the connecting plate 604. When the inclination angle of the connecting plate 604 increases, the connecting plate 604 will pull the first movable plate 601 and the second movable plate 605 to slide horizontally against each other inside the screening chamber 2. The first movable plate 601 and the second movable plate 605 are moved closer together, and the first crushing cone 602 connected to the side walls of the first movable plate 601 and the second movable plate 605 squeezes and crushes the feed accumulated on the vibrating screen plate 8. When the inclination angle of the connecting plate 604 decreases, the first movable plate 601 and the second movable plate 605 are pushed away from each other. At this time, the two second movable plates 605 are moved closer together again, so that the second crushing cone 606 connected to the side walls of the second movable plate 605 squeezes and crushes the feed again, which not only avoids the repeated operation of re-putting the feed into the grinder for crushing, reduces the workload and processing time, and significantly improves the overall production efficiency, but also immediately performs secondary processing on the residual feed during the screening process, reduces the accumulation of feed on the screen plate, thereby improving the continuity and efficiency of screening, and because the accumulation of feed on the vibrating screen plate 8 is reduced, the load of the vibrating screen plate 8 is also reduced, thereby reducing the wear of the vibrating screen plate 8, so that the life of the vibrating screen plate 8 is effectively extended;

[0062] After the vibrating screen plate 8 has screened the feed, the feed that meets the specifications will pass through the sieve holes on the vibrating screen plate 8 and fall into the collecting box 5 at the bottom of the screening chamber 2. At this time, the driving motor 701 connected to the side wall of the screening chamber 2 is opened to drive the reciprocating screw rod 702 to rotate on the screening chamber 2. The reciprocating screw rod 702 and the linkage plate 706 are threadedly connected, so that the linkage plate 706 can drive the spreading plate 703 to move back and forth horizontally above the collecting box 5 inside the screening chamber 2, and the feed accumulated in the upper part of the collecting box 5 is evenly pushed to various places inside the collecting box 5, which not only helps to save space in the collecting box 5 and ensure that the stacking density of the feed is moderate, which is convenient for subsequent storage, transportation and use, but also avoids the situation where the feed in the collecting box 5 is locally accumulated too high, which affects the subsequent staff to take out the collecting box 5 from the inside of the screening chamber 2, so that the staff can smoothly take out the collecting box 5 to pack the screened feed;

[0063] During the horizontal reciprocating movement of the linkage plate 706 along the surface of the reciprocating screw rod 702, the linkage plate 706 can drive the flapping plate 704 to move horizontally and reciprocate synchronously through the extension plate 707 that is slidably connected to it from above. At this time, since both sides of the flapping plate 704 are connected with sliding columns 705, and the sliding columns 705 are slidably connected to the corrugated groove 9, during the horizontal reciprocating movement of the flapping plate 704, it will be affected by the sliding columns 705 and the corrugated groove 9, and move up and down synchronously, so that the vibrating screen plate 8 will flap during the descent process. The beating plate 704 rises synchronously and hits the lower end surface of the vibrating screen plate 8. Moreover, the beating plate 704 follows the horizontal movement of the linkage plate 706 and can hit various parts of the lower end surface of the vibrating screen plate 8. This can not only effectively reduce the blockage of the vibrating screen plate 8, keep the sieve holes unobstructed, and ensure the continuity and stability of the screening process, but also the vibration of the beating plate 704 can directly act on the feed particles on the vibrating screen plate 8, making them looser, thereby improving the fluidity of the feed and making it easier for the feed particles to pass through the sieve holes, thereby increasing the screening speed.

[0064] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well. The present invention is limited only by the claims and their full scope and equivalents.
