Description

Technical Field

[0001] This invention relates to the field of feed mixing technology, specifically to a feed mixing and batching equipment. Background Technology

[0002] As modern animal husbandry develops towards large-scale and intensive operations, higher demands are placed on the nutritional balance, quality stability, and production efficiency of feed products. As the core link in feed processing, the advancement of its technology and equipment directly affects the quality of the final product and production costs.

[0003] In large-scale feed mills, feed mixing equipment is a key piece of equipment for achieving precise formulation and ensuring batch uniformity. Currently, the mainstream mixing system usually consists of a raw material silo, a batching scale, a mixing host, and a conveying device connecting them. However, in the actual production process, there are often technical bottlenecks in the front-end feeding stage of the mixing equipment, which restricts the stable operation of the overall system.

[0004] Currently, most feed mixing equipment uses inclined screw conveyors for feeding. Although this device has a simple structure, it has obvious drawbacks in practical applications: feed raw materials often contain foreign objects that are not feed raw materials. When the feed is lifted by the screw conveyor, the foreign objects cannot be filtered out in time. This not only leads to blockage of the screw blades, which in turn causes equipment failure and shutdown, but also reduces the purity of the mixed feed, which has an adverse effect on the quality of the feed.

[0005] Therefore, it is necessary to propose a feed mixing and batching equipment to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a feed mixing and batching device to solve the problems mentioned in the background art.

A connecting rod is fixedly installed at both ends of the baffles. A crossbar is slidably connected inside each side frame of the screen plate, and all the connecting rods inside each side frame of the screen plate are equidistantly rotatably connected to the inside of the crossbar. A lever is slidably installed in the middle of the outer side of the crossbar. The lever is elastically connected to the screen plate through a first spring installed on its side. The feed hopper is provided with a recycling mechanism for collecting and storing the impurities separated by the screen plate.

[0013] Preferably, the closing mechanism further includes two protruding pillars symmetrically fixed on the inner wall of the feeding barrel for inserting into the inside of the sieve plate frame and pushing the sliding block, and the protruding pillars are located above the rotating clamping plate.

[0014] Preferably, the recycling mechanism includes a debris bin formed in the inner wall of the feeding barrel, the upper end of the debris bin communicating with the interior of the feeding barrel, a baffle rotatably mounted on the top surface of the connection between the debris bin and the feeding barrel, a solid block fixed inside the debris bin, a pair of sliding rods being installed through the lower part of the solid block, one end of the sliding rod abutting against the push bar, the sliding rod being elastically connected to the solid block by a second spring fitted outside it, an arc-shaped block being fixed to the other end of the sliding rod, two gears being symmetrically mounted on the side of the feeding barrel near the mixing barrel, a swing wheel being fixedly mounted on the side of the gears, and a limit wheel being rotatably mounted between the two gears.

[0015] Preferably, a guide frame is fixedly installed between the two material lifting frames. A guide groove is opened through the guide frame. A pair of racks are fixedly installed on the inner side wall of the guide groove. Each gear is meshed with the corresponding rack. The limiting wheel is slidably connected in the guide groove. Two pad rails are symmetrically fixed on the back of the guide frame. A blocking block is fixedly installed on the back of the top of the guide frame.

[0016] Preferably, a pair of locking rods slide through the upper part of the solid block.

Two ear plates are symmetrically fixed at both ends of the side of the bottom door, and the ear plates abut against the corresponding side plates.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention employs a lifting belt to vertically lift and lower the feeding hopper, transferring different raw materials into the mixing hopper. Compared to the traditional inclined screw feeding device, this solution achieves more efficient and thorough transfer of raw materials into the mixing hopper, eliminating the problem of insufficient material retention leading to inadequate material gripping by the transmission method. Furthermore, the feeding hopper is equipped with a sieve plate, which screens the raw materials while lifting them, separating impurities and ensuring the purity of the raw materials. This also eliminates the impact of impurities on the mixing hopper and the finished feed, significantly reducing the maintenance cost of the mixing equipment and improving the quality of the finished feed.

[0020] 2. When the feeding hopper is raised, the rack and gear in the guide groove drive the swing wheel to rotate, which pushes the arc block repeatedly. Then, the slide bar regularly hits the push bar, causing the screen plate to vibrate back and forth inside the feeding hopper, achieving a more efficient screening purpose, avoiding excessive accumulation of raw materials above the screen plate, and further improving the screening effect of the screen plate.

[0021] 3. To avoid obstruction when pouring raw materials from the feeding hopper, the rotating clamp is designed to be rotatable. After the feeding hopper rises to a certain height, the screen plate deflector contacts the blocking block, and the meshing of the toothed plate and toothed ring drives the rotating clamp to rotate, thereby driving the screen plate to rotate. This allows the rotating clamp to fit against the inner wall of the feeding hopper, ensuring that there is no obstruction inside the feeding hopper and making the pouring of raw materials smoother. The rotation of the screen plate not only reduces obstruction to the pouring of raw materials, but also connects the debris bin to the upper part of the feeding hopper through the cooperation of the locking block and the baffle, and sends the impurities on the top surface of the screen plate into the debris bin, preventing impurities from being poured into the mixing hopper. At the same time, it allows the protruding post to insert into the frame of the screen plate, thereby driving the crossbar to slide through the deflector, which in turn drives several baffle strips to rotate, sealing the bottom surface of the screen plate. This prevents raw materials from flowing back through the screen plate and accidentally entering the debris bin during the pouring process, thus preventing inaccurate raw material mixing ratios caused by raw material shortages.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-11 The present invention provides a technical solution: a feed mixing and batching device;

[0036] Example 1: Please refer to the appendix of the instruction manual. Figure 1 , 2 3, 5, 6, 7, and 8, this embodiment describes one implementable structure of a feed mixing and batching device;

[0037] It includes a mixing tank 10, a spiral agitator 11, a conveying hopper 12, and a lifting frame 13. The spiral agitator 11 is rotatably installed inside the mixing tank 10, and the conveying hopper 12 is fixedly installed at the bottom of the mixing tank 10.

[0038] The lifting mechanism includes two lifting frames 13 symmetrically fixed to the side wall of the mixing tank 10. Each lifting frame 13 has a lifting belt 16 slidably installed inside. Each lifting belt 16 has a lifting shaft 17 fixed on its side. A feeding tank 20 is rotatably installed between the two lifting shafts 17. A rotating clamp 22 is rotatably installed on one side inside the feeding tank 20.

[0039] The lifting mechanism also includes a motor 14 fixedly installed on the outside of the bottom end of the lifting frame 13. Two conveyor wheels 15 are rotatably connected to both ends inside each lifting frame 13. The conveyor wheels 15 at the bottom of the lifting frame 13 are fixed to the output end of the corresponding motor 14, and the two conveyor wheels 15 inside each lifting frame 13 are rotatably connected to the corresponding lifting belt 16.

[0040] The screening mechanism includes a screen plate 30 installed inside the feeding barrel 20. The front end of the screen plate 30 is slidably connected to the inside of the rotating clamp 22, and the rear end of the screen plate 30 is slidably connected to the inside of the side of the feeding barrel 20.

[0041] The screening mechanism also includes a support plate 27 at the same horizontal height as the rotating clamp 22 and installed on the inner wall of the other side of the feeding barrel 20. Both the inside of the rotating clamp 22 and the side of the support plate 27 are equipped with oscillating springs 28. The screen plate 30 is elastically connected to the rotating clamp 22 through the oscillating spring 28 inside the rotating clamp 22, and the support plate 27 is elastically connected to the inner wall of the feeding barrel 20 through the oscillating spring 28 on its side.

[0042] In this embodiment, a vertical lifting frame 13 is provided on one side of the conventional mixing tank 10. Inside the lifting frame 13, there is a slidable lifting belt 16 driven by a motor 14. Two lifting shafts 17, which are rotatably arranged on both sides of the feeding tank 20, are respectively fixedly installed on the side walls of the two lifting belts 16. The motor 14 drives the conveyor wheel 15 to rotate, and the conveyor wheel 15 drives the lifting belt 16 to slide upward, thereby driving the feeding tank 20 to rise through the lifting shafts 17.

[0043] The top of the lifting frame 13 features a right-angled structure with an arc transition. When the feeding hopper 20 is lifted to the top of the lifting frame 13, it automatically tilts and pours the internal raw materials into the mixing hopper 10. Compared with the traditional screw conveyor, the vertical lifting and lowering feeding method of the feeding hopper 20 avoids the problem that the screw blades cannot completely grab the raw materials when there are few materials in the hopper, making the transfer of raw materials cleaner and more thorough. This also prevents problems such as low proportioning accuracy caused by some raw materials decreasing in specific gravity during the feed formulation process.

[0044] The inside of the feeding hopper 20 is also equipped with a screen plate 30 supported by a rotating clamp 22 and a support plate 27. When the feeding hopper 20 is on the ground, the screen plate 30 is horizontally separated in the middle of the feeding hopper 20. After the raw material is introduced, including the rising stage of the feeding hopper 20, the screen plate 30 can screen the raw material and separate impurities in the raw material. This not only ensures the purity of the raw material, but also eliminates the impact of impurities on the mixing hopper 10 and the finished feed, greatly reducing the maintenance cost of the mixing equipment and improving the quality of the finished feed.

[0045] Example 2: Please refer to the appendix of the instruction manual. Figure 4 , 5Based on Embodiment 1, this embodiment takes into account two shortcomings of Embodiment 1: First, simply relying on the lifting belt 16 to lift the feeding bucket 20, and then cooperating with the right-angle turn of the top of the lifting frame 13, cannot accurately change the feeding bucket 20 from a vertical posture to a horizontal posture, and even if the feeding bucket 20 is changed to a horizontal posture, the internal raw materials cannot be completely poured out; Second, the sieve plate 30 set inside the feeding bucket 20 plays a negative role in blocking the pouring out of the raw materials during the pouring process, and without treatment, the impurities filtered out by the sieve plate 30 will first be poured into the mixing bucket 10. Therefore, this embodiment solves the problem of pouring raw materials from the feeding bucket 20 through the following structure.

[0046] The rotating clamp 22 is symmetrically fitted with first torsion springs 23 on both sides, and the rotating clamp 22 is elastically connected to the inside of the feeding barrel 20 through the first torsion springs 23. A semi-circular toothed ring 24 is fixed in the middle of the rotating clamp 22. Two locks 25 are symmetrically fixed at the bottom of the rotating clamp 22. Several locking blocks 26 are fixed at equal intervals on the top surface of the rotating clamp 22.

[0047] The recycling mechanism includes a debris bin 40 located in the inner wall of the feeding bin 20 near the mixing bin 10. The upper end of the debris bin 40 is connected to the inside of the feeding bin 20. A baffle 41 is rotatably installed at the top of the connection between the debris bin 40 and the feeding bin 20. A solid block 42 is fixed inside the debris bin 40. A pair of sliding rods 43 are installed through the lower part of the solid block 42. One end of the sliding rod 43 abuts against the push bar 31. A second spring 44 is fitted on the sliding rod 43. The sliding rod 43 is elastically connected to the solid block 42 through the second spring 44. An arc-shaped block 45 is fixed at the other end of the sliding rod 43. Two gears 46 are symmetrically installed on the side of the feeding bin 20 near the mixing bin 10. A swing wheel 47 is fixedly installed on the side of each gear 46. A limit wheel 48 is rotatably installed between the two gears 46.

[0048] The recycling mechanism also includes a bottom door 70 installed at the bottom of the feeding barrel 20. A second torsion spring 71 is sleeved on the bottom door 70 and the rotating part of the feeding barrel 20. The bottom door 70 is elastically connected to the feeding barrel 20 through the second torsion spring 71. Two ear plates 72 are symmetrically fixed at both ends of the side of the bottom door 70, and each ear plate 72 abuts against the corresponding side plate 55.

[0049] The guiding mechanism includes a guide frame 50 fixedly installed between two lifting frames 13. The guide frame 50 has guide grooves 51 symmetrically opened on both sides. A rack 52 is fixedly installed on the inner side wall of the guide groove 51. Each gear 46 meshes with the corresponding rack 52 and slides in the corresponding guide groove 51. Two pad rails 53 are symmetrically fixedly installed on the back of the guide frame 50. A blocking block 54 is fixedly installed on the top back of the guide frame 50. Two side plates 55 are fixedly installed on both sides of the bottom of the guide frame 50.

[0050] The locking mechanism includes a pair of locking rods 60 that slide through the upper part of the solid block 42. One end of each locking rod 60 is inserted into the corresponding latch 25, and the other end of each locking rod 60 abuts against the surface of the corresponding pad rail 53. A third spring 61 is fitted on each locking rod 60. The locking rod 60 is elastically connected to the solid block 42 through the third spring 61. A toothed plate 62 and a fourth spring 64 are installed in the upper part of the solid block 42. The toothed plate 62 is elastically connected to the inside of the solid block 42 through the fourth spring 64, and the toothed plate 62 is engaged with the toothed ring 24. A lever plate 63 is fixed at the bottom of the toothed plate 62 and the lever plate 63 is exposed outside the solid block 42.

[0051] In this embodiment, in addition to being installed together with the lifting belt 16 via the lifting shaft 17, the feeding barrel 20 also extends a pair of support rods from the side of the feeding barrel 20 near the mixing barrel 10. A pair of gears 46 are rotatably installed at the ends of the support rods, and a limiting wheel 48 is rotatably installed between the pair of gears. The limiting wheel 48 rolls inside the guide groove 51 to limit the movement trajectory of the feeding barrel 20 and to prevent the two gears 46 or the feeding barrel 20 from shaking.

[0052] As per the instruction manual Figure 3 It can be seen that the guide groove 51 at the top of the guide frame 50 has a smaller bending angle than the top of the lifting frame 13. When the feeding bucket 20 moves to the top of the lifting frame 13, the guide groove 51 with a lower end can make the opening of the feeding bucket 20 tilt more downward, so that the internal raw material can be poured out more thoroughly, avoiding the problem of raw material loss due to incomplete pouring.

[0053] As per the instruction manual Figure 10 As shown, when the feeding hopper 20 is on the ground, the rotating clamp 22 and the screen plate 30 are in a horizontal state. The ends of the two locking rods 60 abut against the pad guide rail 53. Under the pressure of the pad guide rail 53, the locking rods 60 compress the third spring 61, and the other end inserts into the corresponding lock 25, thus locking the rotating clamp 22. When raw materials are subsequently poured into the feeding hopper 20, the rotating clamp 22 and the screen plate 30 can remain in a horizontal state and will not rotate arbitrarily.

[0054] During the lifting process of the feeding barrel 20, the gear 46 is continuously driven to rotate by the rack 52 in the guide groove 51, thereby causing the swing wheel 47 to move around the center of the gear 46. Whenever the swing wheel 47 touches the arc block 45, it will push the slide rod 43 to slide into the feeding barrel 20, compressing the corresponding second spring 44 and hitting the push bar 31. Since one end of the screen plate 30 is elastically connected to the rotating clamp 22 through the oscillation spring 28, and the other end is placed on the support plate 27, which is elastically connected to the inner wall of the feeding barrel 20 through the oscillation spring 28, the screen plate 30 will vibrate back and forth from the inside of the feeding barrel 20 after each impact of the slide rod 43, achieving a more efficient screening purpose, avoiding excessive accumulation of raw materials above the screen plate 30, and further improving the screening effect of the screen plate 30.

[0055] When the feeding hopper 20 rises to the top bend of the lifting frame 13, as per the instruction manual... Figure 4 As shown, firstly, the locking rod 60 disengages from the raised pad rail 53, and the third spring 61 naturally extends, causing the other end of the locking rod 60 to pop out from the latch 25, thereby releasing the lock on the rotating clamp 22. Subsequently, the lever 63 on the toothed plate 62 will abut against the blocking block 54 on the back of the guide frame 50. The lever 63 is blocked by the blocking block 54 and forces the toothed plate 62 to stop following the movement of the feeding barrel 20, while the feeding barrel 20 continues to move forward, causing the toothed plate 62 to compress the fourth spring 64, and through the toothed ring 24 that meshes with it, drive the rotating clamp 22 and the screen plate 30 to rotate until the rotating clamp 22 and the screen plate 30 rotate to fit against the inner wall of the feeding barrel 20. In this way, when the feeding barrel 20 reaches the top of the lifting frame 13, it is ensured that the screen plate 30 will not block the pouring of the raw material in the feeding barrel 20, effectively reducing the residue of raw material.

[0056] When the rotating clamp 22 is kept horizontal, the several locking blocks 26 on its top just touch the bottom edge of the baffle 41, so that the baffle 41 will not rotate into the debris bin 40. This also prevents some of the raw materials from breaking through the baffle 41 and accidentally entering the debris bin 40 when the raw materials are poured into the feeding bucket 20.

[0057] When the toothed plate 62 starts to drive the rotating clamp 22 and screen plate 30 to rotate through the toothed ring 24, that is, when the feed bucket 20 starts to gradually tilt from vertical to horizontal, the clamping block 26 will no longer restrict the baffle 41. The baffle 41 gradually rotates into the debris bin 40 under its own weight, and the connection between the debris bin 40 and the feed bucket 20 gradually opens.

[0058] As the rotating clamp 22 and the screen plate 30 rotate, the impurities separated from the top surface of the screen plate 30 will continuously roll into the impurity bin 40, thereby playing the function of recovering impurities so as not to affect the effect of subsequent screening of raw materials.

[0059] Example 3: Please refer to the appendix of the instruction manual. Figure 7 ,8 Based on Embodiment 1, this embodiment takes into account that although the screen plate 30 in Embodiment 1 flips with the rotating clamp 22 to fit the inner wall of the feeding bucket 20 to avoid obstructing the pouring of raw materials, the screen plate 30 has a two-way permeable mesh. When the feeding bucket 20 reaches the top of the lifting frame 13 and is poured, the raw materials inside the feeding bucket 20 must pass through the screen plate 30. If the screen plate 30 is not sealed, some raw materials may pass through the screen plate 30 and enter the interior of the debris bin 40, which will also cause the loss of some raw materials. Therefore, this embodiment solves the problem of reverse leakage of the screen plate 30 through the following structure.

[0060] The closing mechanism includes two push bars 31 symmetrically fixed to the bottom front end of the screen plate 30. Several baffle bars 32 are equidistantly arranged on the bottom surface of the screen plate 30, and the two ends of each baffle bar 32 are rotatably connected to the inside of the two side frames of the screen plate 30. Each baffle bar 32 is fixedly installed with a connecting rod 34 at both ends. A crossbar 33 is slidably connected inside each side frame of the screen plate 30, and all connecting rods 34 on the same side are equidistantly rotatably connected to the inside of the crossbar 33. A lever 35 is slidably installed in the middle of the outer side of the crossbar 33. A first spring 36 is installed on the side of the lever 35, and the lever 35 is elastically connected to the inside of the screen plate 30 through the corresponding first spring 36.

[0061] The closing mechanism also includes two protruding posts 21 symmetrically fixed on the inner wall of the feeding barrel 20, and the protruding posts 21 are located above the rotating clamping plate 22. The protruding posts 21 are used to insert into the inside of the frame of the screen plate 30 and push the push block 35 to slide.

[0062] In this embodiment, as per the appendix to the specification... Figure 8 As shown, the bottom of the screen plate 30 is provided with multiple rotatable baffles 32. When the screen plate 30 is horizontally positioned inside the feed hopper 20, under the elastic force of the first spring 36 inside the frame of the screen plate 30, the baffles 32 remain vertical and do not obstruct the material from passing through the screen plate 30. When the screen plate 30 is in contact with the inner wall of the feed hopper 20, the protrusions 21 fixed to the inner wall of the feed hopper 20 will insert into the frame of the screen plate 30 and press the lever 35, causing the lever 35 to be positioned inside the frame of the screen plate 30. The lever 35 slides parallel to the crossbar 33, compresses the first spring 36, and drives the crossbar 33 to slide. The crossbar 33 drives the corresponding baffle strips 32 to rotate 90 degrees through several connecting rods 34, thereby achieving the effect of closing the screen plate 30. In this way, when pouring raw materials, no raw materials will pass through the screen plate 30, and no raw materials will enter the interior of the waste bin 40. This ensures that the raw materials are fully poured into the mixing tank 10, avoiding the problem of inaccurate raw material mixing ratio caused by raw material shortage.

[0063] Working principle: When the feeding hopper 20 is on the ground, raw materials are poured into it. The screen plate 30 built into the feeding hopper 20 can screen the poured raw materials and separate impurities. After the raw materials are poured in, the motor 14 drives the lifting belt 16 to rotate inside the lifting frame 13 through the conveyor wheel 15. The lifting belt 16 then lifts the feeding hopper 20 through the lifting shaft 17.

[0064] During the lifting process, the screen plate 30 continuously filters the raw materials, and the rack 52 in the guide groove 51 drives the gear 46 to rotate continuously. The gear 46 drives the swing wheel 47 to rotate circumferentially. Whenever the swing wheel 47 touches the arc block 45, it will squeeze the arc block 45, causing the arc block 45 to drive the slide rod 43 to slide a certain distance into the feed barrel 20. While the slide rod 43 compresses the second spring 44, it hits the corresponding push bar 31. The push bar 31 is fixed to the bottom of the screen plate 30, and both ends of the screen plate 30 are equipped with vibration springs 28. Therefore, every time the slide rod 43 hits the push bar 31 and releases the push bar 31, it will cause the screen plate 30 to vibrate inside the feed barrel 20, thereby better screening the raw materials and accelerating the falling speed of the raw materials, preventing the raw materials from accumulating above the screen plate 30.

[0065] When the feed bucket 20 is raised to the top of the lifting frame 13, the raw materials are screened. At this time, the rack 52 reaches its limit and will not drive the gear 46 and the swing wheel 47 to rotate. The slide bar 43 will not resist the push bar 31, and the screen plate 30 returns to a stationary state.

[0066] Then the feed hopper 20 begins to tilt gradually. Subsequently, the end of the locking rod 60 inside the solid block 42 disengages from the pad guide rail 53. Under the elastic force of the third spring 61, the other end of the locking rod 60 pops out from the latch 25 and engages the locking of the rotating clamp 22. Then the lever 63 abuts against the blocking block 54, causing the rack 52 to slide. Through the gear ring 24, the rotating clamp 22 and the screen plate 30 are rotated until the screen plate 30 is attached to the inner wall of the feed hopper 20.

[0067] During this process, the rotation of the clamping plate 22 and the screen plate 30 not only opens the feed bucket 20, allowing the internal raw materials to be poured out smoothly, but also removes the obstruction of the baffle 41 by the locking block 26, causing the baffle 41 to rotate and open the connection between the debris bin 40 and the inside of the feed bucket 20, allowing all impurities to be discharged into the debris bin 40. At the same time, the protruding post 21 can be inserted into the frame of the screen plate 30, pushing the lever 35 to slide, thereby causing the crossbar 33 to slide, and then through several connecting rods 34 to drive the corresponding baffle strip 32 to rotate 90 degrees, finally closing the bottom surface of the screen plate 30. In this way, during the process of pouring raw materials from the feed bucket 20, the raw materials will not pass through the screen plate 30 in the opposite direction and accidentally enter the debris bin 40, thus avoiding the loss of raw materials.

[0068] When the feeding bucket 20 is raised to the top of the lifting frame 13, since the top of the guide frame 50 is lower than the bottom of the lifting frame 13, the opening of the feeding bucket 20 is tilted downwards when it is in this position. This ensures that the raw materials in the feeding bucket 20 can be fully poured into the mixing bucket 10, reducing raw material loss and improving the accuracy of mixing and batching.

[0069] After the dumping is completed, the motor 14 drives the conveyor wheel 15 to reverse. The conveyor wheel 15 drives the feeding bucket 20 to reset through the lifting belt 16 and the lifting shaft 17. During the reset process, the blocking block 54 no longer applies resistance to the blocking plate 63. Under the elastic force of the fourth spring 64, the feeding bucket 20 and the toothed plate 62 move relative to each other. The toothed plate 62 drives the rotating clamp 22 and the screen plate 30 to rotate through the toothed ring 24. Finally, the rotating clamp 22 and the screen plate 30 return to the above-mentioned "horizontal state". The locking block 26 on the top surface of the rotating clamp 22 will also push the baffle 41 to re-close the connection between the debris bin 40 and the inside of the feeding bucket 20.

[0070] Subsequently, the two locking rods 60 also slide back onto the corresponding pad rails 53, and the pad rails 53 cause the locking rods 60 to compress the third spring 61 again and re-insert into the corresponding latches 25 to lock the rotating clamp 22.

[0071] After the screen plate 30 rotates, the protruding post 21 disengages from the inside of the frame of the screen plate 30 and no longer abuts against the corresponding push block 35. Then, under the elastic force of the first spring 36, the push block 35 drives the crossbar 33 to reset, and the crossbar 33 drives the baffle strip 32 to reset through the connecting rod 34.

[0072] When the feed hopper 20 descends vertically to near the ground, the two ear plates 72 at the bottom of the debris bin 40 abut against the side plates 55 on both sides of the bottom of the guide frame 50. The side plates 55 push the ear plates 72 upward, causing the bottom door 70 to rotate downward. At the same time, the second torsion spring 71 is charged when the debris bin 40 is opened. After the debris bin 40 is opened, all the previously recovered impurities fall out.
