Description

Technical Field

[0001] The invention relates to the technical field of straw crushing devices, and specifically relates to a silage straw feed crushing device. Background Art

[0002] Straw is the main by-product of crops, and crop straw can be used as fertilizer, feed, and fuel for daily life. There are two ways to deal with straw: direct burning and straw recycling. Direct burning of straw will cause environmental pollution and waste of resources, while straw recycling can store straw for green storage, promote agricultural and animal husbandry development, and protect the ecological environment. After the existing crushing device crushes the straw, it is also necessary to screen the straw to collect qualified materials and unqualified materials respectively. For example, the Chinese invention patent with patent application number "CN202110069772.0" provides a straw green storage crushing device, which includes a crushing mechanism and a screening mechanism. When the device is working, the moving knife group drives the fixed knife group to rotate to crush the straw green storage, and then pulls the second sealing plate to release the crushed straw green storage into the screening mechanism for screening.

[0003] The disadvantage of the device is that the screening mechanism includes a screen plate and a vibration motor, and the screen plate is arranged at an angle. Therefore, when the vibration motor drives the screen plate to vibrate and screens the straw crushed materials, the straw crushed materials on the top of the screen plate will gather on the right side of the screen plate. In other words, the left side of the screen plate is in an idle state, which will reduce the screening speed of the straw crushed materials. Summary of the invention

[0004] The object of the present invention is to provide a green storage straw feed crushing device, in which two arc-shaped screens in the screening component together form a hemispherical shape.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0039] Embodiment 1

[0040] See also Figure 1-18 The present invention provides a technical solution: a silage straw feed crushing device, comprising a crushing component 1 and a screening component 2. The crushing component 1 comprises a crushing box 11, in which a crusher 12 is arranged. The screening component 2 comprises a screening box 21, two assembly frames 22, two arc-shaped screens 23 and a vibration motor 24. The structures of the two assembly frames 22 are mirror-symmetrical, and the assembly frames 22 comprise a first arc-shaped plate 221 and a second arc-shaped plate 222, and the two ends of the second arc-shaped plate 222 are respectively fixedly connected to the two ends of the first arc-shaped plate 221. The two arc-shaped screens 23 are respectively fixedly arranged on the two assembly frames 22, and the shapes of the two arc-shaped screens 23 are both one-quarter spheres. The vibration motor 24 is arranged below the assembly frame 22, and the output end of the vibration motor 24 is connected to the assembly frame 22.

[0041] See also Figure 1, Figure 5-6 , Fig.15 and Fig.17 When the present invention is used, the straw is first placed into the crushing box 11 from the discharge port at the top of the crushing box 11, and then the crusher 12 works to complete the crushing of the straw. (The crusher 12 belongs to the prior art, and its structure is not repeated.) Since the interior of the screening box 21 is connected to the interior of the crushing box 11, the straw crushed material will fall downward into the screening box 21. At this time, the two first arc plates 221 are enclosed together to form a ring structure, and the two second arc plates 222 are attached to each other, so the two arc screens 23 together form a hemispherical shape. After falling, the straw crushed material will be caught by the two arc screens 23. Then the vibration motor 24 works, driving the two assembly frames 22 to vibrate, and then driving the arc screen 23 to vibrate. Qualified straw crushed material is screened by the arc screen 23, falls to the bottom of the arc screen 23 and is collected, and unqualified straw crushed material will remain on the inner side of the two arc screens 23. Since the shape of the arc screen 23 is a quarter sphere, when the arc screen 23 vibrates, the straw crushed materials inside the two arc screens 23 will be bounced to the center of the assembly frame 22, and then fall back onto the two arc screens 23 under the influence of gravity. Since the arc screen 23 will not tilt during the vibration process, the arc screens 23 on both sides can complete the screening of the straw crushed materials without any idle area, thereby improving the screening speed of the straw crushed materials.

[0042] Embodiment 2

[0043] See also Figure 5 and Figure 17-18 On the basis of the first embodiment, the present invention further comprises a first rotating drive assembly 3 and a material shifting assembly 4. The first rotating drive assembly 3 can drive the two assembly frames 22 to rotate, so that the two second arc-shaped plates 222 are separated, and unqualified straw crushed materials can also fall down and be collected. The material shifting assembly 4 can contact the straw crushed materials when the arc-shaped screen 23 vibrates, break up the straw crushed materials, avoid agglomeration of the straw crushed materials, and further improve the screening speed of the straw crushed materials.

[0044] See also Figure 5-7The first rotary drive assembly 3 includes two first support plates 31, two second support plates 32, two gears 33, a rotating shaft 34 and two racks 35. The two first support plates 31 and the two second support plates 32 are fixedly arranged on the two first arc-shaped plates 221, respectively, and the two second support plates 32 are located between the two first support plates 31. The two gears 33 are arranged between the two second support plates 32 and are fixedly connected to the two second support plates 32, respectively. The centers of the two gears 33 are provided with first avoidance holes 331, and the two ends of the rotating shaft 34 pass through the two first avoidance holes 331, respectively. The two first support plates 31 and the two second support plates 32 are rotatably connected to the rotating shaft 34. The two racks 35 are arranged above the assembly frame 22 and are respectively arranged on both sides of the rotating shaft 34.

[0045] See also Figure 5-7 and Figure 17-18 , when the vibration motor 24 drives the two assembly frames 22 to vibrate, the gear 33 does not contact the rack 35, so the two assembly frames 22 will not rotate. When the screening process is over, the vibration motor 24 will stop working. After the qualified straw crushing materials are collected, the vibration motor 24 is lifted up to drive the two assembly frames 22 to move upward together. When the gear 33 contacts the rack 35, the rack 35 drives the gear 33 to rotate around the rotating shaft 34, and the gear 33 drives the assembly frame 22 to rotate upward around the rotating shaft 34. Then the two second arc plates 222 separate, and when the gear 33 rotates 90°, the unqualified straw crushing materials will fall down and leave the arc screen 23, and then be collected. Next, put down the vibration motor 24, drive the two assembly frames 22 to move downward together, and the gear 33 drives the assembly frame 22 to rotate downward around the rotating shaft 34. When the gear 33 leaves the rack 35, the two second arc plates 222 are re-attached, and the assembly frame 22 is reset.

[0046] See also Figure 5 , Fig. 9 , Fig.13 and Figure 17-18 The material-digging assembly 4 includes a material-digging box 41, a conical block 42, a vertical rod 43 and a plurality of elastic material-digging plates 44. The material-digging box 41 is arranged on the inner side of the two assembly frames 22, and the conical block 42 is arranged on the top of the material-digging box 41. The bottom surface of the material-digging box 41 is provided with a vertical rod 43, the first end of the vertical rod 43 is fixedly connected to the material-digging box 41, the second end of the vertical rod 43 is fixedly connected to the output end of the vibration motor 24, and the plurality of elastic material-digging plates 44 are arranged on the outer side wall of the material-digging box 41.

[0047] When the straw crushing material enters the screening box 21, it will fall onto the conical block 42 and slide down along the side wall of the conical block 42 to the inner side of the two arc-shaped screens 23, preventing the straw crushing material from accumulating on the top surface of the material-dividing box 41. In addition, since the assembly frame 22 is connected to the rotating shaft 34, the rotating shaft 34 is connected to the conical block 42, the conical block 42 is connected to the material-dividing box 41, and the material-dividing box 41 is connected to the output end of the vibration motor 24 through the vertical rod 43, the vibration motor 24 can transmit the vibration to the assembly frame 22. In the process of the assembly frame 22 driving the arc-shaped screen 23 to vibrate, the arc-shaped screen 23 will bounce the straw crushing material to the material-dividing box 41, at which time the straw crushing material will contact a plurality of elastic material-dividing plates 44, which can break up the straw crushing material to prevent the straw crushing material from agglomerating.

[0048] Embodiment 3

[0049] See also Figure 9-11 and Figure 17-18 On the basis of the second embodiment, the first end of the elastic material-diverting plate 44 is fixedly connected to the top of the outer wall of the material-diverting box 41, and the bottom surface of the material-diverting box 41 is provided with a plurality of second avoidance holes 411, and the second ends of the plurality of elastic material-diverting plates 44 respectively pass through the plurality of second avoidance holes 411 and extend to the inner side of the material-diverting box 41. The material-diverting assembly 4 also includes a second rotary drive assembly 45, which is arranged on the inner side of the material-diverting box 41, and the second ends of the plurality of elastic material-diverting plates 44 are all connected to the output end of the second rotary drive assembly 45. In the process of the assembly frame 22 driving the arc screen 23 to vibrate, the second rotary drive assembly 45 can drive the second ends of the plurality of elastic material-diverting plates 44 to swing back and forth, and the elastic material-diverting plates 44 undergo elastic deformation. Therefore, after the elastic material-diverting plate 44 contacts the straw crushing material, the position of the straw crushing material on the inner side of the arc screen 23 can be changed.

[0050] See also Figure 9-12 The elastic material-diverting plate 44 is in a C-shaped structure. A plurality of material-diverting pieces 441 are fixedly arranged on the side walls on both sides of the elastic material-diverting plate 44. The plurality of material-diverting pieces 441 on different sides are staggered. The angle between the material-diverting piece 441 and the elastic material-diverting plate 44 is greater than 90°. The elastic material-diverting plate 44 and the material-diverting piece 441 cooperate to collide with the straw crushing material. When the straw crushing material is broken up, there will be no idle area on the arc screen 23, so that the straw crushing material is evenly distributed on the arc screen 23.

[0051] See also Fig.11The second rotary drive assembly 45 includes a driving disc 451, a plurality of rollers 452 and a rotary motor 453. When the second rotary drive assembly 45 is working, the rotary motor 453 drives the driving disc 451 to rotate forward first, then reverse, and repeat several times. The driving disc 451 can drive the second end of the elastic material stripping plate 44 to swing back and forth, and at this time, the second end of the elastic material stripping plate 44 slides along the inner side wall of the second avoidance hole 411. The rollers 452 can roll along the inner wall of the material stripping box 41 to enhance the stability of the driving disc 451 and the elastic material stripping plate 44 during the movement.

[0052] See also Figure 1-2 , Figure 4-5 and Figure 17-18 The side wall of the screening box 21 is provided with a first assembly hole 211 and a second assembly hole 212. A first material collecting box 213 is provided in the first assembly hole 211, and a second material collecting box 214 is provided in the second assembly hole 212. The two first material collecting boxes 213 are provided with a first arc groove 2131 on the opposite end faces, and the two second material collecting boxes 214 are provided with a second arc groove 2141 on the opposite end faces. A first bearing plate 215 is provided on the outer side wall of the screening box 21 and below the first assembly hole 211, and a second bearing plate 216 is provided on the outer side wall of the screening box 21 and below the second assembly hole 212.

[0053] See also Figure 1-2 , Figure 5 , Fig.13 and Fig.17 Before the present invention is used, the two second material collecting boxes 214 are pulled out, and the second bearing plate 216 provides support for the second material collecting boxes 214. Then, the two first material collecting boxes 213 are pushed inward, and the vertical rod 43 fits with the inner wall of the first arc-shaped groove 2131, and the two first material collecting boxes 213 are abutted together. In the process of the assembly frame 22 driving the arc-shaped screen 23 to vibrate, the assembly frame 22 will not collide with the second material collecting box 214, and the qualified straw crushed materials fall into the two first material collecting boxes 213 and are collected.

[0054] See also Figure 1-2 , Figure 5 , Fig.13 and Fig.18, when the screening process is finished, the two first collection boxes 213 are pulled out, and the first bearing plate 215 provides support for the first collection boxes 213, so that the qualified straw crushing materials can be taken away. Then the vibration motor 24 is lifted upward, driving the two assembly frames 22 to move upward together, and when the bottom of the arc screen 23 moves to the top of the second bearing plate 216, the two second collection boxes 214 are pushed inward, and the vertical rod 43 fits the inner side wall of the second arc groove 2141, and the two second collection boxes 214 are abutted together. At this time, the gear 33 is still at a distance from the rack 35 and will not contact the rack 35. Then continue to lift the vibration motor 24 upward, and the vertical rod 43 slides along the inner side wall of the second arc groove 2141 until the gear 33 rotates 90°, and the unqualified straw crushing materials will fall down into the two second collection boxes 214 and be collected. Finally, the two second material collecting boxes 214 are pulled outward, the vibration motor 24 is put down, the two second arc-shaped plates 222 are again attached to each other, and the assembly frame 22 is reset.

[0055] Embodiment 4

The limiting ring 52 is fixedly connected to the inner wall of the screening box 21, and the assembly frame 22 is arranged on the inner side of the limiting ring 52. The two linear drivers 53 are both arranged on the outer side of the screening box 21, and the output end of the linear driver 53 is connected to the end of the positioning seat 51. The linear driver 53 can drive the positioning seat 51 to move upward or downward, and then drive the vibration motor 24 to move upward or downward to adjust the position of the assembly frame 22. During the movement of the assembly frame 22, the first arc plate 221 can slide along the inner side wall of the limiting ring 52. The limiting ring 52 can limit the assembly frame 22, and ensure that the two assembly frames 22 will not rotate at will during the vibration of the assembly frame 22 and the upward or downward movement of the assembly frame 22. Therefore, when the gear 33 is not in contact with the rack 35, the two second arc plates 222 will not separate.

[0057] See also Figure 1-2 , Figure 5 and Fig.13The adjustment seat 51 includes a bearing plate 511, two driving rods 512 and two springs 513. The vibration motor 24 is fixedly connected to the bearing plate 511, and the two driving rods 512 are respectively arranged on both sides of the bearing plate 511. The first end of the driving rod 512 is fixedly connected to the bearing plate 511, and the second end of the driving rod 512 passes through the third avoidance hole 217 and extends to the outside of the screening box 21. The two springs 513 are respectively arranged in the two third avoidance holes 217, and the first end of the spring 513 is fixedly connected to the inner wall of the third avoidance hole 217, and the second end of the spring 513 is detachably connected to the second end of the driving rod 512. The linear drive 53 includes a first rectangular frame 531, a second rectangular frame 532 and an electric telescopic rod 533, and the first rectangular frame 531 is fixedly arranged on the top surface of the second end of the driving rod 512. The second rectangular frame 532 is sleeved on the top of the first rectangular frame 531, and the bottom of the second rectangular frame 532 passes through the inside of the first rectangular frame 531. The electric telescopic rod 533 is fixedly arranged on the side wall of the screening box 21 , and the output end of the electric telescopic rod 533 faces downward and is fixedly connected to the second rectangular frame 532 .

[0058] See also Figure 1-2 , Figure 5 , Fig.13 and Fig.17 Before the vibration motor 24 works, the electric telescopic rod 533 is in an extended state, there is a gap between the bottom of the second rectangular frame 532 and the top of the first rectangular frame 531, and the spring 513 is connected to the driving rod 512. After the vibration motor 24 works, in the process of the assembly frame 22 driving the arc screen 23 to vibrate, the spring 513 plays a buffering role, the adjustment seat 51 and the first rectangular frame 531 will vibrate together with the vibration motor 24, and at this time, the second rectangular frame 532 does not contact the first rectangular frame 531, so it plays a role in protecting the electric telescopic rod 533.

[0059] When the vibration motor 24 stops working, the second end of the spring 513 is removed from the driving rod 512. The electric telescopic rod 533 is shortened, first driving the second rectangular frame 532 to move upward, and when the second rectangular frame 532 contacts the first rectangular frame 531, the adjustment seat 51 is driven to move upward through the first rectangular frame 531, and finally the assembly frame 22 is driven to move upward. When the unqualified straw crushing materials are collected, the electric telescopic rod 533 is extended, which can drive the adjustment seat 51 to move downward, and then drive the assembly frame 22 to move downward. When the assembly frame 22 is reset, the electric telescopic rod 533 continues to extend, the second rectangular frame 532 is separated from the first rectangular frame 531, and then the second end of the spring 513 is reconnected with the driving rod 512.

[0060] See also Figure 5-8 and Figure 13-14, a third arc-shaped groove 2221 is provided at the bottom center of the second arc-shaped plate 222, a plug hole 2222 is provided on the inner side wall of the third arc-shaped groove 2221, and a plug plate 431 is fixedly provided on the side wall of the vertical rod 43. In the present invention, the vertical rod 43 is located on the inner side of the third arc-shaped groove 2221, so that the vertical rod 43 can pass through the second support plate 32, and the two second arc-shaped plates 222 can fit together. When the second arc-shaped plates 222 fit together, the plug plate 431 extends into the plug hole 2222. When the assembly frame 22 moves upward and leaves the limit ring 52, and the gear 33 has not yet contacted the rack 35, the two plug plates 431 can restrict the two second arc-shaped plates 222 from rotating, and unqualified straw crushing materials will not spill out. The two plug plates 431 are both made of rubber material and can be elastically deformed. When the gear 33 contacts the rack 35 , the plug plates 431 can be separated from the insertion hole 2222 , and the two second arc-shaped plates 222 can rotate.

[0061] See also Figure 3 , Figure 5 and Figure 17-18 The top surface of the limiting ring 52 is provided with a recovery cover 521, which is trumpet-shaped, and the diameter of the top of the recovery cover 521 is larger than the diameter of the bottom. When the assembly frame 22 drives the arc screen 23 to vibrate, even if some straw crushing materials are bounced to a position higher than the first arc plate 221, they can be blocked by the recovery cover 521 and slide down along the side wall of the recovery cover 521 and return to the inner side of the two arc screens 23, ensuring that the straw crushing materials will not be spilled during the screening process.

[0062] See also Figure 1-3 and Figure 15-18 The bottom surface of the crushing box 11 is provided with a discharge hole 111, and a retaining ring 13 is provided below the discharge hole 111. An assembly rod 131 is respectively provided at both ends of the outer wall of the retaining ring 13, and the first ends of the two assembly rods 131 are fixedly connected to the retaining ring 13, and the second ends of the two assembly rods 131 are respectively fixedly connected to the two racks 35. After the crusher 12 works and completes the crushing of the straw, the crushed straw material will fall downward through the discharge hole 111 into the screening box 21. Since the diameter of the retaining ring 13 is smaller than the diameter of the top of the recovery cover 521, the crushed straw material will be restricted by the retaining ring 13, ensuring that all the crushed straw material can fall into the inner side of the recovery cover 521, and finally all fall into the inner side of the two arc-shaped screens 23 without spilling out. The assembly rod 131 is connected to the two racks 35 to ensure the stability of the racks 35. When the gear 33 contacts the racks 35, the gear 33 and the racks 35 can mesh correctly to ensure that the assembly frame 22 can rotate correctly.
