Description

Technical Field

[0001] The invention belongs to the technical field of forage processing, and in particular relates to a forage conveying and recycling device for producing mixed grass pellet feed. Background Art

[0002] In the field of animal husbandry, making forage into pellets for feeding can reduce the waste of forage and thus improve feed utilization. Livestock can also grind their teeth when chewing feed strips. In terms of transportation, the feed squeezed into strips has a higher density, which reduces the volume of the feed and makes it easier to package and transport. During rough processing, the bundled forage rolls need to be crushed, and the crushed forage is conveyed through the forage conveyor line, and the forage is sucked into the next production link through the air conveyor. However, since the equipment of the entire production line is relatively large and the staff need to manually remove the tying strips on the bales, it is time-consuming and inefficient to transport. In addition, during transportation, the forage at the edge of the forage conveyor line will fall to the ground, resulting in the forage not being fully utilized.

[0016] Beneficial effects: Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the direction adjustment structure can be used to dynamically adjust the cutting blade according to the forward and backward movement state of the docking slider, which is convenient and quick.

[0017] 2. In the present invention, when moving forward for cutting, through the provided rectangular top block and arc surface portion, when the arc surface portion touches the side edges of the rectangular top block, the docking slider will be lifted up, causing the docking slider to rotate clockwise with the docking axis as the rotation center, and as the docking slider continues to move forward, when the vertical surface of the rectangular top block abuts against the bottom of the docking slider, the cutting blade on the docking slider is vertical to the ground, and the cutting blade extends from the cutting guide groove to cut off the bundled edge strips.

[0018] 3. In the present invention, when moving backward to reset, the docking slider and the cutting blade will be retracted into the first top groove under the cooperation of the first docking shaft and the shaft limiting groove, preventing the back of the cutting blade from interfering with the straw bale when moving backward.

[0019] Fourth, in the present invention, the slide bar is pushed upward by the telescopic end of the hydraulic rod, and the first slide bar lifts one side of the bale positioning arc plate. At this time, the bale positioning arc plate will rotate counterclockwise with the shaft rod, and the bale in the bale positioning arc plate can be discharged.

[0020] 5. In the present invention, when the ratchet wheel rotates, it will push the bending plate outward through the ratchet teeth on the ratchet wheel, so that the bending plate drives the pulling sleeve rod to slide outward, and then pulls the material receiving part, and the material receiving part at the bottom of the forage guide plate moves. When the pulling sleeve rod slides outward, the first spring is compressed. As the ratchet wheel rotates, when the ratchet teeth separate from the bending plate, the first spring will stretch and reset, causing the pulling sleeve rod to slide inward, and then reset the material receiving part. By continuously pulling and resetting the material receiving part, the material receiving part is shaken, thereby improving the efficiency of forage movement.

[0021] 6. In the present invention, when the material receiving part vibrates, it will touch the end of the delivery plate, causing the delivery plate to vibrate as well, thereby shaking the grass on the delivery plate to the spoon-shaped end. When the electromagnet is energized, it will generate a magnetic pole opposite to the magnetic block. Under the action of the mutual attraction of the two magnetic forces, the magnetic block will move downward and be adsorbed with the electromagnet. At the same time, the magnetic block will drive the vertical pressure plate to move downward along the second slide groove. At this time, the vertical pressure plate squeezes the delivery plate, causing the delivery plate to rotate counterclockwise, thereby re-delivering the grass in the spoon-shaped end of the delivery plate to the grass conveyor belt for secondary adsorption and transmission by the first air conveyor.

[0022] 7. In the present invention, the high end of the second filter screen plate is continuously moved up and down by the cooperation of the cam and the push slider, thereby shaking and screening the hay, stones and other debris on the second filter screen plate. The hay falls into the hay recovery chamber along the mesh of the second filter screen plate, and the stones and other debris fall into the recovery box along the low end of the second filter screen plate for recovery, thereby realizing the separation of hay and debris.

[0023] 8. In the present invention, when cleaning and recovery are required, the device is placed in an offline state, and the locking rod is pulled out. At this time, the third spring in a compressed state will stretch and reset, and then push the magnetic plate mounting door outward to separate the first magnetic plate from the second window. When the magnetic plate mounting door moves outward, the folding bag at the bottom will be stretched open, so that the staff can clean the grass in the grass recovery chamber into the folding bag, so that the staff can carry the cleaned grass, so that the grass cleaned later can be processed later without the need for additional demagnetization.

Under the meshing action, the first rack 232 and the second rack 233 begin to slide forward, and the first rack 232 drives the pull rod 226 to move forward through the docking block 227. The pull rod 226 pushes the first docking shaft 220 to slide forward along the shaft limiting groove 219, thereby driving the docking slider 221 and the cutting blade 22 plugged on the docking slider 221 to move forward. During the forward movement of the docking slider 221, when the arc surface 224 touches the side edge corner of the rectangular top block 223, the docking slider 221 will be lifted up, so that the docking slider 221 rotates clockwise with the first docking shaft 220 as the rotation center, and continues to move forward with the docking slider 221. When the vertical surface of the rectangular top block 223 abuts against the bottom of the docking slider 221, the cutting blade 22 on the docking slider 221 is vertical to the ground, and the cutting blade 22 extends from the cutting guide groove 24. At this time, as the docking slider 221 continues to move forward, the docking slider 221 will push the rectangular top block 223, and the cross sliding block 216 will slide forward along the limiting guide rail 26, thereby causing the cutting blade 22 to move forward along the cutting guide groove 24, cutting the bottom of the bale stuck on the bale positioning arc plate 23, and cutting off the tying edge strips tied on the bale.

[0030] like Fig.12As shown, a rope gathering assembly is provided on one side of the bale positioning arc plate 23, and the rope gathering assembly includes a limiting outer frame 234 and a bending member 235. The top of the limiting outer frame 234 is fixedly connected to the bottom of the second rack 233 located above, and the bending member 235 is rotatably connected to the inner wall of the limiting outer frame 234. Specifically, during the cutting process, the second rack 233 will also slide forward synchronously under the action of meshing, thereby driving the limiting outer frame 234 and the bending member 235 to move forward, and the limiting outer frame 234 and the bending member 235 will move forward. The bottom of the bending member 235 is inclined, and the bottom of the inner wall thereof abuts against the bottom of the bending member 235; thus, when the bending member 235 moves forward, the bottom of the bending member 235 forms an angle with the top of the straw bale, and the resistance between the bending member 235 and the upper surface of the straw bale becomes larger. At the same time, the bottom of the inner wall of the limiting outer frame 234 limits the bending member 235, thereby improving the stability during pushing, so as to facilitate the forward pushing of the cut tying edge strip and push out the cut tying edge strip; The bending member 235 is located on the side of the second rack 233 close to the first rotating motor 228, so that in the process of moving forward, the bundled edge strips are first cut and then the cut bundled edge strips are pushed out; Specifically, after the cutting is completed, the first rotating motor 228 drives the two driving gears 229 to rotate clockwise through the rotating shaft. Under the meshing action, the first rack 232 and the second rack 233 begin to slide backward, and the first rack 232 drives the pull rod 226 to move backward through the docking block 227. The pull rod 226 pulls the first docking shaft 220 to slide backward along the shaft limiting groove 219, thereby driving the docking slider 221 and the cutting blade 22 inserted on the docking slider 221 to move backward. During the backward movement of the docking slider 221, the U The inner wall of the card plate 225 will block the docking slider 221. As the pull rod 226 continues to pull the first docking shaft 220 to slide backward along the shaft limiting groove 219, the docking slider 221 and the cutting blade 22 are retracted into the first top groove 217 to prevent the back of the cutting blade 22 from interfering with the bale when it moves backward. When the first docking shaft 220 slides to the side of the shaft limiting groove 219 close to the first rotating motor 228, the first docking shaft 220 will push the inner wall of the shaft limiting groove 219, thereby driving the cross sliding block 216 to slide backward and reset. At the same time, the second rack 233 will also slide backward synchronously under the action of meshing, thereby driving the limiting outer frame 234 and the bending piece 235 to move backward. At this time, the bottom of the inner wall of the limiting outer frame 234 will not limit the bending piece 235. At the same time, when the bending piece 235 contacts the upper surface of the straw bale, the bending piece 235 will rotate clockwise in the limiting outer frame 234 to facilitate the resetting of the bending piece 235.

[0031] like Figure 3-Figure 7As shown, a lifting structure is provided at the bottom of the bale positioning arc plate 23, and the lifting structure includes a lifting hydraulic rod 27 and a limiting sleeve rod 28. The lifting hydraulic rod 27 is symmetrically installed on the support platform 29. A sliding groove 210 is provided on the side of the bale positioning arc plate 23 close to the support platform 29. The telescopic end of the lifting hydraulic rod 27 is rotatably connected to a first sliding rod 211. Both ends of the first sliding rod 211 are slidably connected to the sliding groove 210. The sliding groove 210 is provided to allow the first sliding rod 211 to slide in the sliding groove 210 to prevent interference during lifting. A plurality of sets of limiting sleeve rods 28 are fixedly connected to the first base 21, and a connecting ear 212 corresponding to the plurality of sets of limiting sleeve rods 28 is fixedly connected to the bottom of the bale positioning arc plate 23 away from the supporting platform 29, and the plurality of connecting ears 212 are fixedly connected to the same shaft rod 213, and the top of the limiting sleeve rod 28 is rotatably sleeved on the shaft rod 213; Specifically, after the direction adjustment structure, the rope gathering assembly and the first driving structure are reset, the lifting hydraulic rod 27 is turned on, and the first slide bar 211 is pushed upward by the telescopic end of the lifting hydraulic rod 27. The first slide bar 211 lifts one side of the bale positioning arc plate 23. At this time, the bale positioning arc plate 23 will rotate counterclockwise with the shaft rod 213, and the bales in the bale positioning arc plate 23 will be discharged into the grass scrambler 3 to scramble the bales.

[0032] Embodiment 2 like Figure 1-Figure 33 As shown, this embodiment is improved as follows based on the first embodiment: Fig.13 As shown, the forage transport line 4 includes a connecting frame 41 and a forage conveyor belt 42 installed on the connecting frame 41. The discharge port of the forage scatterer 3 is located above one end of the forage conveyor belt 42. The forage scatterer 3 discharges the scattered forage onto the forage conveyor belt 42. A first air conveyor 43 fixedly connected to the connecting frame 41 is arranged above the other end of the forage conveyor belt 42. The forage is transported along the direction of the first air conveyor 43 through the forage conveyor belt 42. The forage is adsorbed and transmitted to the forage crushing line 5 by the first air conveyor 43. A residual material recovery structure is symmetrically arranged on the inner wall of the connecting frame 41. The residual material recovery structure is located below the forage conveyor belt 42. A delivery structure is arranged on the inner wall of the connecting frame 41. like Fig.18 As shown, a second base 44 is provided at the bottom of the connecting frame 41, and the residual material recovery structure includes a forage guide plate 45 symmetrically arranged on the inner wall of the connecting frame 41, and the two forage guide plates 45 are arranged in an inclined shape, and a bent material receiving portion 46 is provided at the bottom of the forage guide plate 45, and the bent material receiving portion 46 can better collect the forage; like Fig. 20 and Fig.21As shown, the residual material recovery structure also includes a pulling sleeve rod 47 and a sliding block 48. A first sliding groove 412 is provided on the side wall of the material receiving portion 46. The sliding block 48 is slidably connected to the first sliding groove 412. A connecting shaft 413 is rotatably connected to the sliding block 48. One end of the pulling sleeve rod 47 is rotatably sleeved on the connecting shaft 413. The pulling sleeve rod 47 pulls the sliding block 48 through the connecting shaft 413, thereby driving the material receiving portion 46 to move. The sliding block 48 slides in the first sliding groove 412 to avoid interference. The free end of the pulling sleeve rod 47 penetrates the connecting frame 41 and extends outside, and an interface 414 is provided at the end thereof, and a bending plate 415 is plugged into the interface 414 through a first bolt. The waste material recovery structure also includes a ratchet 416. The outer side wall of the connecting frame 41 is fixedly connected to a plurality of groups of docking bases 418 corresponding to the ratchet 416, and each group of docking bases 418 is rotatably connected to a first pin shaft 417, and the ratchet 416 is fixedly connected to the first pin shaft 417, and the ratchet 416 is intermittently in contact with the bending plate 415; A first limit plate 419 is fixedly connected to the pulling sleeve rod 47, and a first spring 420 is sleeved on the pulling sleeve rod 47. Two ends of the first spring 420 are respectively fixedly connected to the inner wall of the connecting frame 41 and the first limit plate 419; Specifically, when the ratchet 416 rotates, it will push the bending plate 415 outward through the ratchet teeth on the ratchet 416, so that the bending plate 415 drives the pulling sleeve rod 47 to slide outward, and then pulls the material receiving part 46, and the material receiving part 46 at the bottom of the forage guide 45 moves. When the pulling sleeve rod 47 slides outward, the first spring 420 is compressed. As the ratchet 416 rotates, when the ratchet teeth separate from the bending plate 415, the first spring 420 will stretch and reset, causing the pulling sleeve rod 47 to slide inward, and then reset the material receiving part 46. By continuously pulling and resetting the material receiving part 46, the material receiving part 46 is shaken, thereby improving the efficiency of forage movement.

[0033] like Fig.18 As shown, the delivery structure includes a delivery plate 421 and a vertical pressure plate 422, and the delivery plate 421 is rotatably connected to the connecting frame 41, as shown in FIG. Fig.14 As shown, a second slide groove 423 is provided on the connecting frame 41, and the vertical pressing plate 422 is slidably connected with the second slide groove 423. The vertical pressing plate 422 is located above the delivery plate 421, and a gap is left between the vertical pressing plate 422 and the delivery plate 421 to prevent the vertical pressing plate 422 from blocking the grass. Both ends of the vertical pressing plate 422 pass through the second slide groove 423 and extend outside, and both ends of the vertical pressing plate 422 are provided with a second driving structure. like Fig.14 , Fig. 22 and Fig.23As shown, magnetic blocks 424 are embedded in the side parts of both ends of the vertical pressure plate 422, and the two second driving structures include a card seat 425 installed on the second base 44, and an electromagnet 426 is installed at the bottom of the card seat 425. The electromagnet 426 is located directly below the magnetic block 424, and when the electromagnet 426 is not powered, the magnetic pole of the electromagnet 426 is the same as the magnetic pole of the magnetic block 424, and the two electromagnets 426 are connected to the external control terminal for signal transmission; One end of the delivery plate 421 contacts the bottom of the two forage guide plates 45, and the other end of the delivery plate 421 is spoon-shaped. A limiting groove 427 adapted to the spoon-shaped end of the delivery plate 421 is provided on the upper surface of the second base 44. A spring docking seat 428 is symmetrically fixedly connected to the upper surface of the second base 44. The top of the spring docking seat 428 is inclined, and the top of the spring docking seat 428 abuts against the bottom of the delivery plate 421. When the top of the spring docking seat 428 abuts against the bottom of the delivery plate 421, the delivery plate 421 is inclined. A second slide bar 429 is slidably connected to the spring docking seat 428, and a second spring 430 is sleeved on the second slide bar 429. The two ends of the second spring 430 are fixedly connected to the spring docking seat 428 and the second slide bar 429 respectively. The second sliding bar 429 is located below the delivery plate 421; Specifically, as the receiving portion 46 vibrates, the grass on the receiving portion 46 will be shaken off onto the delivery plate 421. When the receiving portion 46 vibrates, it will touch the end of the delivery plate 421, causing the delivery plate 421 to also vibrate, thereby shaking off the grass on the delivery plate 421 to the spoon-shaped end. When the electromagnet 426 is energized, it will generate a magnetic pole opposite to the magnetic block 424. Under the action of the two magnetic forces adsorbing each other, the magnetic block 424 will move downward to be adsorbed by the electromagnet 426. At the same time, the magnetic block 424 will drive the vertical pressing plate 422 to move downward along the second slide groove 423. At this time, the vertical pressing plate 422 squeezes the delivery plate 421, causing the delivery plate 421 to rotate counterclockwise, thereby re-delivering the grass in the spoon-shaped end of the delivery plate 421 onto the grass conveyor belt 42 for secondary adsorption and transmission by the first air conveyor 43. When the delivery plate 421 rotates counterclockwise, one end of the delivery plate 421 will separate from the forage guide plate 45 and squeeze the second slide bar 429. At this time, the second spring 430 is compressed. After the delivery is completed, the electromagnet 426 is powered off. The magnetic poles of the electromagnet 426 and the magnetic block 424 are the same. At this time, the magnetic block 424 moves upward and resets under the action of the mutual repulsion of the two magnetic forces. At the same time, the magnetic block 424 drives the vertical pressure plate 422 to move upward and reset along the second slide groove 423. At this time, the second spring 430 in a compressed state is stretched and reset, and squeezes the delivery plate 421 through the second slide bar 429. At this time, the spoon-shaped end of the delivery plate 421 will tilt and rotate and reset under the action of its own gravity.

[0034] like Fig.14 and Fig.18 As shown, a residual material box 431 is detachably embedded on the second base 44, and the side of the forage conveyor belt 42 and the two forage guide plates 45 close to the first air conveyor 43 are all located directly above the residual material box 431. When the delivery plate 421 rotates counterclockwise, one end of the delivery plate 421 will separate from the forage guide plate 45, and at this time, the forage on the forage guide plate 45 will fall into the residual material box 431 and be collected, so as to prevent the forage on the forage guide plate 45 from accumulating on the second base 44 when the delivery plate 421 is delivering the forage; like Fig.14 , Fig.15 and Fig.17 As shown, two second docking shafts 432 corresponding to the residual material recovery structure are rotatably connected to the second base 44, and the first pin shaft 417 is transmission-connected to the corresponding second docking shafts 432 through a second transmission belt 433; A driving gear 434 is fixedly connected to one of the second docking shafts 432, and a second pin shaft 435 is symmetrically rotatably connected to the connecting frame 41. A direction-changing gear 49 meshing with the driving gear 434 is fixedly connected to the second pin shaft 435. A first transmission belt 410 is sleeved on the second pin shaft 435. The other second docking shaft 432 is transmission-connected to the second pin shaft 435 via the first transmission belt 410. like Fig.13 As shown, a second rotating motor 411 is mounted on the second base 44, and a rotating shaft of the second rotating motor 411 is fixedly connected to a second docking shaft 432 fixedly connected to a driving gear 434; Specifically, the second rotating motor 411 drives the second docking shaft 432 fixedly connected to the driving gear 434 to rotate clockwise through the rotating shaft, and the second docking shaft 432 drives the first pin shaft 417 and the ratchet 416 fixedly connected to the first pin shaft 417 to rotate clockwise through the second transmission belt 433, and the changing gear 49 meshing with the driving gear 434 through meshing and the second pin shaft 435 fixedly connected to the changing gear 49 rotate counterclockwise, and drives another second docking shaft 432 to rotate counterclockwise through the first transmission belt 410, and the second docking shaft 432 drives the first pin shaft 417 and the ratchet 416 fixedly connected to the first pin shaft 417 to rotate counterclockwise through the second transmission belt 433, so that the ratchet 416 can push the bending plate 415 outward when rotating.

[0035] Embodiment 3 like Figure 1-Figure 33 As shown, this embodiment is improved as follows based on the first embodiment: Fig.24As shown, the forage demagnetization wire 7 includes a forage conveying bin 71 and a feed port 72 and a feed port 73 connected to both sides of the forage conveying bin 71. The feed port 72 is connected to the air outlet of the second air conveyor 6. The second air conveyor 6 transports the crushed forage to the feed port 72 through the air outlet. Fig.26 As shown, the forage conveying bin 71 is provided with a second magnetic plate 736 which is connected to the discharge port 73; Fig. 27 As shown, the interior of the forage conveying bin 71 is provided with a filtering chamber 74, a debris separation chamber 75 and a forage recovery chamber 76 in order from top to bottom; like Fig. 27 As shown, a first filter screen plate 77 fixedly connected to the forage conveying bin 71 is disposed in the filter cavity 74, and the first filter screen plate 77 is disposed in an inclined shape, and a lower end of the first filter screen plate 77 is connected to the feed inlet 72, and a higher end of the first filter screen plate 77 is connected to the discharge port 73; like Figure 27-Figure 31 As shown, a second filter screen plate 78 rotatably connected to the forage conveying bin 71 is provided in the debris separation chamber 75, a shaking structure is provided inside the forage conveying bin 71, a support frame 79 is provided inside the forage conveying bin 71, and a recovery box 710 connected to the second filter screen plate 78 is placed in the support frame 79; a second top groove 711 connected to the bottom of the recovery box 710 is provided at the bottom of the support frame 79, and the second top groove 711 is connected to the forage recovery chamber 76; During operation, the second air conveyor 6 transports the crushed grass to the feed port 72 through the air outlet, and the grass will pass through the filter chamber 74 and be discharged along the discharge port 73. During this process, the second magnetic plate 736 will adsorb the magnetic substance in the grass, thereby separating the magnetic impurities. The demagnetized grass will be discharged to the subsequent production link through the discharge port 73. When the grass is air-conveyed, the stones and other debris in the grass will be located at the bottom of the grass due to the large gravity. When passing through the filter chamber 74, the stones and other debris will be blocked by the first filter screen plate 77 and fall into the debris separation chamber 75 along the mesh of the first filter screen plate 77. At the same time, some of the grass will fall into the second filter screen plate 78 in the debris separation chamber 75 together with the stones and other debris.

[0036] Furthermore, the second filter screen plate 78 is arranged in an inclined shape, and the lower end of the second filter screen plate 78 is rotatably connected to the forage conveying bin 71, such as Fig.30 and Fig.31 As shown, a double-headed motor 712 is installed inside the forage conveying bin 71, and the shaking structure includes a push slider 714. The two push sliders 714 are symmetrically slidably connected inside the forage conveying bin 71. Cams 713 are fixedly connected to the two rotating shafts of the double-headed motor 712. The cams 713 are located just below the push sliders 714. The bottoms of both sides of the second filter screen plate 78 near the high end are in contact with the tops of the two push sliders 714. like Fig.31 As shown, the two push sliders 714 are each provided with a first embedding groove 715 on the side away from each other, a third spring 716 is slidably embedded in the first embedding groove 715, a slide plate 717 slidably connected to the first embedding groove 715 is provided inside the forage conveying bin 71, one end of the third spring 716 is fixedly connected to the inner wall of the first embedding groove 715, and the other end is fixedly connected to the slide plate 717; Further, such as Fig.30 As shown, a second limit plate 718 is provided inside the forage conveying bin 71, and the high end of the second filter screen 78 is located below the second limit plate 718. The second limit plate 718 can prevent the high end of the second filter screen 78 from excessively moving upward and failing to return to its original position. The double-headed motor 712 drives the two cams 713 to rotate through the rotating shaft. When the cam 713 rotates, the raised portion of the cam 713 pushes the push slider 714 upward, causing the push slider 714 to slide upward, thereby causing the high end of the second filter screen plate 78 to move upward. When the push slider 714 slides upward, the slide plate 717 applies pressure to the third spring 716, and the third spring 716 is compressed. As the cam 713 continues to rotate, the raised portion gradually stops contacting with the push slider 714, and the cam 713 exerts pressure on the push slider 714. The thrust gradually decreases, and the third spring 716 in the compressed state is stretched and reset, pushing the top slider 714 downward, thereby moving the high end of the second filter screen plate 78 downward; the high end of the second filter screen plate 78 continuously moves up and down, thereby shaking and screening the hay, stones and other debris on the second filter screen plate 78, and the hay falls into the hay recovery chamber 76 along the mesh of the second filter screen plate 78, and the stones and other debris will fall into the recovery box 710 along the low end of the second filter screen plate 78 for recovery.

[0037] like Fig.24 and Fig.28 As shown, a first window 719 communicating with the debris separation chamber 75 is provided on one side of the forage conveying bin 71, and a lower end of the second filter screen plate 78 is communicated with the recovery box 710; A first visual window 721 connected to the first window 719 is installed on one side of the forage conveying bin 71 through a second bolt 720. The first visual window 721 is used to observe the working condition of the debris separation chamber 75. A demagnetization structure for demagnetizing the forage is provided in the forage recovery chamber 76; Fig.26 and Fig. 27As shown, the magnetic structure includes two stirring rods 722 rotatably connected to the forage conveying bin 71, the bottoms of the two stirring rods 722 slide through the forage conveying bin 71 and extend outside, and the two stirring rods 722 are connected by a third transmission belt 723, a third rotating motor 724 is installed at the bottom of the forage conveying bin 71, and the rotating shaft of the third rotating motor 724 is fixedly connected to one of the stirring rods 722, and the forage in the forage conveying bin 71 is stirred by the stirring rods 722; like Fig.28 As shown, a second window 726 communicating with the forage recovery chamber 76 is provided on one side of the forage delivery bin 71. Fig.32 and Fig.33 As shown, the demagnetization structure also includes a magnetic plate mounting door 727 and a first magnetic plate 728 mounted on the magnetic plate mounting door 727. During the stirring process, the magnetic impurities in the forage are adsorbed by the first magnetic plate 728. The magnetic plate mounting door 727 is slidably connected to the forage conveying bin 71 through two groups of third sliding bars 729. The first magnetic plate 728 is engaged with the second window 726. The two groups of third sliding bars 729 are each provided with a second embedding groove 730. A plurality of second embedding grooves 730 are each slidably embedded with a fifth spring 731. A limiting slider 732 slidably connected to the second embedding groove 730 is fixedly connected to the forage conveying bin 71. One end of the fifth spring 731 is fixedly connected to the inner wall of the second embedding groove 730, and the other end is fixedly connected to the limiting slider 732. The limiting slider 732 and the corresponding third slider 729 are plugged with the same locking rod 733; A second visual window 725 communicating with the forage recovery chamber 76 is provided on one side of the forage delivery bin 71; like Fig.24 and Fig.25 As shown, hooks 734 are provided at the bottom of the forage conveying bin 71 and the magnetic plate installation door 727, and the same folding bag 735 is hung on the multiple hooks 734; When cleaning and recycling is required, the device is placed in an offline state, and the locking rod 733 is pulled out. At this time, the fifth spring 731 in a compressed state will be stretched and reset, thereby pushing the magnetic plate installation door 727 outward to separate the first magnetic plate 728 from the second window 726. When the magnetic plate installation door 727 moves outward, the folding bag 735 at the bottom will be stretched open, so that the staff can clean the grass in the grass recovery chamber 76 into the folding bag 735, so that the staff can carry the cleaned grass. During the mixing process, the magnetic impurities in the grass are adsorbed by the first magnetic plate 728, so that the grass cleaned later can be processed later without additional demagnetization. At the same time, remove the second bolt 720, take off the first visible window 721, reach one hand into the forage recovery chamber 76 through the second window 726, and push the recovery box 710 upward along the second top groove 711 to separate the recovery box 710 from the support frame 79, and reach the other hand into the debris separation chamber 75 through the first window 719 to take the recovery box 710 out of the support frame 79 for cleaning.

[0038] After cleaning, the recovery box 710 is put back into the support frame 79, and the first visible window 721 is installed on the forage conveying bin 71 through the second bolt 720. At the same time, the magnetic plate installation door 727 is pushed inward to engage the first magnetic plate 728 with the second window 726. At this time, the fifth spring 731 is compressed, and the locking rod 733 is used to insert and limit the limiting slider 732 and the corresponding third slider 729, thereby limiting the magnetic plate installation door 727.

[0039] In summary, the workflow of the present invention is: The bales are transported to the bale loosening line 2 by the bale transport equipment 1 to remove the tying edge strips on the bales, and the bales after removal are transported to the hay breakers 3 by the bale loosening line 2 to break the bales. The broken hay will be discharged to the hay transport line 4, and the hay on the hay transport line 4 is transported to the hay crushing line 5 for crushing by the first air conveyor 43. The crushed hay is transported to the hay demagnetization line 7 by the second air conveyor 6 for demagnetization. The demagnetized hay is discharged through the discharge port 73 to the subsequent production link.
