Description

Technical Field

[0001] This invention relates to the field of agricultural production technology, specifically to a forage grading and feeding device. Background Technology

[0002] With the booming development of animal husbandry, forage grass is the main food source for livestock, and its quality control is of paramount importance. In the traditional forage grass processing process, there are many drawbacks in the feeding and screening stages, which seriously restrict the improvement of production efficiency and feed quality.

[0003] Early forage screening devices mostly used a single screen structure, which could not effectively classify forage according to length, fineness, etc. This resulted in the inability to accurately provide feed of appropriate particle size when feeding livestock at different growth stages or of different species, affecting livestock growth and development while increasing feed loss.

[0004] Common feeding devices lack the ability to precisely control the flow of forage. Often, a large amount of forage is dumped into the screen at once, and the forage piles up and rolls around on the screen in a disorderly manner. This causes short grass to become entangled and mixed with long grass, and fine and whole grass, making it difficult to achieve efficient screening and prolonging the overall processing time. This cannot meet the needs of large-scale farming for rapid feed supply.

[0005] In the past, screening equipment was mostly in a fixed state during operation, and the screen could not be flexibly adjusted according to the screening progress. When too much pasture was piled up in the area and the initial screening was completed, it could not be automatically transferred to the subsequent process, which affected the efficiency of the screening work.

[0006] Therefore, a forage grading and feeding device is proposed. Summary of the Invention

[0011] Preferably, the support frame is internally equipped with a lifting assembly, which includes a lifting platform slidably connected to the top of the support frame. The top of the lifting platform is symmetrically connected to load-bearing wheels, each load-bearing wheel being limited and sliding against the outer wall of the second sieve barrel. A first gear is rotatably connected to the middle of the lifting platform. A disc is fixedly connected to one end of the first gear located on the inner wall of the support frame. A shaft is eccentrically fixedly connected to the side of the disc away from the first gear. A fixed seat is fixedly connected to the inner wall of the support frame below the disc. A connecting rod is rotatably connected between the fixed seat and the shaft. Slow-release cylinders are symmetrically fixedly connected between the lifting platform and the support frame. A gear ring is fixedly connected to the side of the second sieve barrel away from the first sieve barrel, and the gear ring meshes with the first gear.

[0012] Preferably, a combing assembly is installed on the outside of the first sieve barrel. The combing assembly includes a second gear rotatably connected to the outer wall of the second circular plate. A third spring is fixedly connected between the second gear and the second circular plate. A lead screw is rotatably connected to the outer wall of the second circular plate and below the second gear. A second transmission belt is drivingly connected between the lead screw and the second gear. Slip rings are symmetrically slidably connected to the outer wall of the lead screw. The inner walls of the slip rings are all in contact with the outer wall of the first sieve barrel. The inner walls of the slip rings are all fixedly connected with comb teeth in a ring array.

[0015] Preferably, the outer wall of the lead screw is symmetrically provided with sliding grooves, and each of the slip rings is fixedly connected with a protrusion, which is slidably connected to the inside of the sliding groove of the lead screw.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. After the forage is fed into the second sieve, the partition component intermittently separates the middle of the first and second sieves, so as to control the forage entering the first sieve from the second sieve and avoid the problem that the first and second sieves cannot screen the forage due to the simultaneous movement of the forage. By setting different apertures in the first and second sieves, the device can realize multi-stage screening and feeding of forage with a single drive source, thereby improving the screening efficiency of forage.

[0018] 2. Through the intermittent meshing of the gear ring and the first gear, the first gear can drive the disc and shaft to rotate through intermittent rotation, so that the lifting platform can slide upward on the top of the support when the first gear rotates. This causes the first and second sieves to tilt under the lifting action of the lifting platform, so that the hay inside the first and second sieves can be displaced when tilted, and the hay can be transferred from the inside of the second sieve to the inside of the first sieve, realizing the multi-stage automatic screening of hay by the equipment.

[0019] 3. By sliding the slip ring relative to the outer wall of the first sieve bucket, the comb teeth comb the hay inside the first sieve bucket, solving the problem of hay clumping and being difficult to sieve after being put into the second sieve bucket. The comb teeth comb the hay as they slide, changing the hay from a curved state to a vertical state, making it easier for workers to collect and process the hay after it has been sieved through the first sieve bucket.

[0036] Embodiments of the present invention

[0037] Please see Figures 1 to 7 A forage grading and feeding device includes a first sieve 5, a second sieve 6, and a partition assembly 8 disposed between the first sieve 5 and the second sieve 6. The partition assembly 8 includes a first circular plate 81 fixedly connected to the side of the second sieve 6 near the first sieve 5, a second circular plate 87 fixedly connected to the side of the first sieve 5 near the second sieve 6, a limiting ring 83 rotatably connected between the first circular plate 81 and the second circular plate 87, a hexagonal groove 82 opened on the side of the first circular plate 81 near the second circular plate 87, straight grooves 84 distributed in a ring array inside the limiting ring 83, a first circular rod 85 slidably connected inside each straight groove 84, baffles 86 fixedly connected to both ends of the first circular rod 85, the outer walls of the multiple baffles 86 abutting each other, and a fixing rod 88 fixedly connected in a ring array between the second circular plate 87 and the first circular plate 81.

[0038] The partition assembly 8 also includes an arc-shaped groove 89 formed at the bottom of the first circular plate 81. A second circular rod 810 is fixedly connected to the outer wall of the first circular plate 81. The second circular rod 810 is slidably connected to the arc-shaped groove 89. A column 811 is fixedly connected to the end of the second circular rod 810 away from the limiting ring 83. Vertical grooves 812 are symmetrically formed on the outer wall of the column 811. A sliding rod 813 is slidably connected inside the column 811. A first spring 814 is fixedly connected between the top of the sliding rod 813 and the top of the inner cavity of the column 811. An inclined groove 815 is formed on the surface of the sliding rod 813. A circular plate 81 has arc-shaped baffles 816 symmetrically fixedly connected to its outer wall. Slider 817 is fixedly connected to the side of the arc-shaped baffles 816 that is close to each other. A second circular rod 810 has arc-shaped rods 818 symmetrically fixedly connected to its outer wall. The arc-shaped rods 818 are slidably connected to the inside of the arc-shaped baffles 816. A second spring 819 is fixedly connected between the second circular rod 810 and the arc-shaped baffles 816. The second spring 819 is sleeved on the outer wall of the arc-shaped rod 818. A protective shell 820 is fixedly connected to the outer wall of the first circular plate 81. The protective shell 820 is sleeved on the outside of the arc-shaped baffles 816.

[0039] The top of the bracket 1 is provided with a protective shell 820. The bottom of the slide rod 813 is engaged inside the protective shell 820 at the top of the bracket 1. The width of the vertical groove 812 is equal to the width of the slider 817. The distance from the slider 817 to the axis of the limiting ring 83 is equal to the distance from the inclined groove 815 on the slide rod 813 to the axis of the limiting ring 83.

[0040] In practical application, the user starts the motor 2. When the output shaft of the motor 2 rotates, it drives the drive wheel 4 to rotate through the first transmission belt 3. When the drive wheel 4 rotates, it will drive the first sieve 5 to rotate together through meshing. Since the first sieve 5 and the second sieve 6 are fixedly connected by a fixing rod 88, the first sieve 5 and the second sieve 6 will rotate synchronously. Then, the staff puts the hay into the second sieve 6. The hay put into the second sieve 6 will be repeatedly lifted and fallen under the action of the rotation of the second sieve 6. The shorter and sparser parts of the hay will pass through the surface of the second sieve 6 and fall onto the top of the support 1 during the rotation of the second sieve 6.

[0041] During the synchronous rotation of the first circular plate 81 and the second circular plate 87, the first circular plate 81 will drive the second circular rod 810 to rotate together with the first circular plate 81 via the arc-shaped baffle 816, the arc-shaped rod 818, and the second spring 819. The rotation of the first circular plate 81 will cause the limiting ring 83 to rotate synchronously with the first circular plate 81. During the synchronous rotation of the limiting ring 83 and the first circular plate 81, the baffle 86 does not form an obstruction between the first screen barrel 5 and the second screen barrel 6. When the sliding rod 813 rotates together with the second circular rod 810 to press against the top of the support 1, the sliding rod 813 will be inside the column 811. The sliding mechanism causes the first spring 814 to be compressed and elastically contracted. When the sliding rod 813 rotates to a vertical position, the inclined groove 815 will spring into the inside of the slot 821. After the sliding rod 813 is locked and limited, the limiting ring 83 cannot rotate. At this time, the first circular plate 81 continues to rotate, which will cause the second spring 819 to be compressed and elastically contracted. At the same time, the first circular rod 85 sliding inside the hexagonal groove 82 will converge, thereby shortening the distance between the multiple baffles 86, thus blocking the first sieve 5 and the second sieve 6, preventing the hay from moving directly from the second sieve 6 to the first sieve 5.

[0042] When the first circular plate 81 rotates, the slider 817 on the arc-shaped baffle 816 and the inclined groove 815 on the slide rod 813 are pressed together. The slide rod 813 slides upward inside the column 811 due to the pressure on the inclined surface of the inclined groove 815. After the slide rod 813 slides upward, it no longer engages with the slot 821. The second spring 819 rebounds after being no longer compressed, and the second circular rod 810 slides to the middle of the arc-shaped groove 89, thereby increasing the spacing of the baffles 86 and connecting the first screen barrel 5 and the second screen barrel 6 without being blocked by the baffles 86.

[0043] After the forage is fed into the second sieve 6, the partition component 8 intermittently separates the middle of the first sieve 5 and the second sieve 6, thus controlling the forage entering the first sieve 5 from the second sieve 6. This prevents the forage from moving simultaneously, which would make it difficult for the first sieve 5 and the second sieve 6 to screen the forage. By setting different apertures in the first sieve 5 and the second sieve 6, the device can achieve multi-stage screening and feeding of forage with a single drive source, thereby improving the screening efficiency of forage.

[0044] Please see Figures 8 to 10 A bracket 1 is installed at the bottom of the first screen barrel 5 and the second screen barrel 6. A motor 2 is installed on the outer wall of the bracket 1. A drive wheel 4 is rotatably connected to the top of the bracket 1. The drive wheel 4 meshes with the first screen barrel 5. A first transmission belt 3 is connected between the drive wheel 4 and the output shaft of the motor 2. A cover 10 is installed on the side of the first screen barrel 5 away from the second screen barrel 6.

[0045] The support frame 1 is equipped with a lifting assembly 7. The lifting assembly 7 includes a lifting platform 79 slidably connected to the top of the support frame 1. The top of the lifting platform 79 is symmetrically rotatably connected to a load-bearing wheel 71. The load-bearing wheel 71 is limited to slide on the outer wall of the second screen barrel 6. The middle of the lifting platform 79 is rotatably connected to a first gear 72. One end of the first gear 72 located on the inner wall of the support frame 1 is fixedly connected to a disc 73. The side of the disc 73 away from the first gear 72 is eccentrically fixedly connected to a shaft 74. The inner wall of the support frame 1 and below the disc 73 is fixedly connected to a fixed seat 75. A connecting rod 76 is rotatably connected between the fixed seat 75 and the shaft 74. A slow-release cylinder 77 is symmetrically fixedly connected between the lifting platform 79 and the support frame 1. The side of the second screen barrel 6 away from the first screen barrel 5 is fixedly connected to a gear ring 78. The gear ring 78 meshes with the first gear 72.

[0046] When the slow-release cylinder 77 is not retracted, the second sieve 6 at the top of the load-bearing wheel 71 is in a horizontal state. The outer wall of the second sieve 6 is provided with an annular groove, and the load-bearing wheel 71 is slidably connected to the inside of the annular groove of the second sieve 6.

[0047] In practical application, during the rotation of the second sieve barrel 6, the toothed ring 78 rotates together with the second sieve barrel 6. When the toothed ring 78 rotates to mesh with the first gear 72, the first gear 72 rotates due to the meshing action. The rotation of the first gear 72 drives the disc 73 to rotate together. When the disc 73 rotates, the horizontal height of the shaft 74 will move up and down accordingly. At this time, because the connecting rod 76 is rotatably connected between the fixed seat 75 and the shaft 74, as the shaft 74 rotates upward, the distance between the lifting platform 79 and the bracket 1 increases. The lifting platform 79 rises and drives the second sieve barrel 6 to rise together. At this time, the side of the first sieve barrel 5 and the second sieve barrel 6 closest to the lifting platform 79 tilts downward, so that the hay inside the second sieve barrel 6 moves into the interior of the first sieve barrel 5 after sieving, and is sieved again as the first sieve barrel 5 rotates.

[0048] When the gear ring 78 rotates until it no longer meshes with the first gear 72, the slow-release cylinder 77 is compressed by the second sieve 6 at the top and slowly contracts, so that the first sieve 5 and the second sieve 6 are adjusted to a horizontal state. When the forage rotates inside the first sieve 5 and the second sieve 6, it cannot move laterally and can only be continuously sieved.

[0049] Through the intermittent meshing of the gear ring 78 and the first gear 72, the first gear 72 can drive the disc 73 and the shaft 74 to rotate through intermittent rotation. This allows the lifting platform 79 to slide upward on the top of the support 1 when the first gear 72 rotates. As a result, the first sieve barrel 5 and the second sieve barrel 6 tilt under the lifting action of the lifting platform 79, allowing the forage inside the first sieve barrel 5 and the second sieve barrel 6 to be displaced when tilted. This allows the forage to be transferred from inside the second sieve barrel 6 to inside the first sieve barrel 5, realizing the multi-stage automatic screening of forage by the equipment.

[0050] Please see Figures 1 to 3 A combing assembly 9 is installed on the outside of the first sieve barrel 5. The combing assembly 9 includes a second gear 91 rotatably connected to the outer wall of the second circular plate 87. A third spring 92 is fixedly connected between the second gear 91 and the second circular plate 87. A lead screw 94 is rotatably connected to the outer wall of the second circular plate 87 and below the second gear 91. A second transmission belt 93 is drivingly connected between the lead screw 94 and the second gear 91. Slip rings 95 are symmetrically slidably connected to the outer wall of the lead screw 94. The inner walls of the slip rings 95 are all in contact with the outer wall of the first sieve barrel 5. The inner walls of the slip rings 95 are all fixedly connected with comb teeth 96 in a ring array. An arc-shaped toothed plate 97 is fixedly connected to the top of the support 1. The arc-shaped toothed plate 97 meshes with the second gear 91.

[0051] The outer wall of the lead screw 94 is symmetrically provided with grooves, and the inside of each slip ring 95 is fixedly connected with a protrusion, which is slidably connected inside the groove of the lead screw 94.

[0052] In practical application, when the second circular plate 87 rotates, it drives the second gear 91 to rotate together. When the third spring 92 rotates to mesh with the arc-shaped toothed plate 97, the second gear 91 rotates and causes the third spring 92 to twist. When the second gear 91 rotates, it drives the lead screw 94 to rotate together through the second transmission belt 93. At this time, because the outer wall of the lead screw 94 is symmetrically provided with sliding grooves, and the sliding grooves are symmetrically connected with sliding rings 95, the rotation of the lead screw 94 will cause the two sliding rings 95 to move relatively away under the combined limiting action of the first screen barrel 5 and the lead screw 94. When the device moves, the comb teeth 96 on its inner wall will slide inside the first sieve 5. When the comb teeth 96 slide inside the second sieve 6, they will comb the hay filled inside the second sieve 6, making the hay flat inside the first sieve 5, which is convenient for the first sieve 5 to sieve hay of different grades. When the second gear 91 no longer meshes with the arc-shaped tooth plate 97, the torque of the third spring 92 rebounds, causing the second gear 91 to rotate in the opposite direction to restore its original position. At this time, the two slip rings 95 move relatively close to each other, so that the hay in the first sieve 5 can be separated when it is clumped together, thus improving the sieve efficiency.

[0053] By sliding the slip ring 95 relative to the outer wall of the first sieve bucket 5, the comb teeth 96 comb the forage inside the first sieve bucket 5, solving the problem of the forage clumping and being difficult to sieve after being put into the second sieve bucket 6. By combing the forage as the comb teeth 96 slide, the forage changes from a curved state to a vertical state, making it easier for workers to collect and process the forage after it passes through the first sieve bucket 5.
