Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a feeding clamping structure. Background Art

[0002] In modern agricultural production, straw is an economical and affordable feed resource, especially for ruminants such as cattle and sheep. The long cellulose in straw is essential for their healthy digestion. Long-fiber feed helps these animals decompose and absorb nutrients more efficiently by promoting the rumination process and microbial fermentation. Therefore, straw is cut short. Compared with crushed feed, long-fiber feed can maintain the stability of the ruminant's stomach environment, provide necessary crude fiber, promote intestinal peristalsis, and thus help prevent digestive problems such as gastric tumors and gastric torsion.

[0003] In the existing straw processing process, straw cutting usually relies on manual labor or simple mechanical equipment. Although these methods can achieve straw cutting to a certain extent, they have the problem of low efficiency. Manual straw cutting is time-consuming and labor-intensive, and traditional cutting equipment is often of a single design and cannot achieve the integration of multiple operations such as feeding, clamping and cutting, resulting in the entire processing process being intermittent and inefficient. How to invent a method to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

DETAILED DESCRIPTION

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 making creative efforts are within the scope of protection of the present invention.

[0021] Example, see Figure 1The top of the support frame 4 is fixedly connected to a plurality of upright frames 2, and the tops of the plurality of upright frames 2 are fixedly connected to two supporting bars 4, and a discharge plate 3 is fixedly connected between the two supporting bars 4, and a plurality of feeding rollers 6 are rotatably connected between the two supporting bars 4. The top of the support bar 4 is fixedly connected to a plurality of pressure plate brackets 7, and the tops of the plurality of pressure plate brackets 7 are slidably connected to a pushing frame 9. The bottom column of the pushing frame 9 penetrates the top of the pressure plate bracket 7 and is slidably arranged. The bottom of the pushing frame 9 is fixedly connected to a pressure plate structure 8, and the top of the pressure plate bracket 7 is fixedly connected to a plurality of cylinder brackets 10. The plurality of cylinder brackets 10 are all fixedly connected to a cylinder 11, and the bottom of the cylinder 11 is fixedly sleeved with a push rod 12, and the bottom of the push rod 12 is fixedly connected to the top of the pushing frame 9. The upright frame 2 is fixedly connected to a motor bracket 14, and the motor bracket 14 is fixedly connected to a motor 13. The output end of the motor 13 is fixedly sleeved with an output shaft 15, and the pressure plate structure 8 is pressed down to clamp the straw placed above the feeding roller 6.

[0022] Reference Figure 1-Figure 3 The bottom of the discharge plate 3 is fixedly connected to a support block 21, and the support block 21 is rotatably connected to the transmission rod 16 and the gear shaft 17. One side of one support column 4 is fixedly connected to a support frame 22, and the support frame 22 is rotatably connected to the half-toothed shaft 18 and the threaded shaft 19. One end of the transmission rod 16 is fixedly sleeved with a cutter 20. The output shaft 15 and the transmission rod 16 are connected by a belt drive. The transmission rod 16 and the gear shaft 17, the gear shaft 17 and the half-toothed shaft 18 are connected by meshing gears. The half-toothed shaft 18 and the threaded shaft 19 are connected by a half gear 23. The outer wall of the threaded shaft 19 is rotatably connected to the push plate 5. The bottom of the pusher plate 5 is slidably arranged with the top of the discharge plate 3. One end of the half-toothed shaft 18 is fixedly sleeved with a half-gear 23, and one end of the threaded shaft 19 is fixedly sleeved with a gear. The half-gear 23 is meshed with the gear. The half-gear 23 on the half-toothed shaft 18 will rotate to a position meshing with the gear on the threaded shaft 19 after the cutter 20 cuts the straw but before the next cutting begins, so that the threaded shaft 19 drives the pusher plate 5 in the direction of the cutter 20 and rotates to a gearless position before the next cutter 20 cuts the straw, completing the separation of the gear meshing, and the push of the pusher plate 5 does not interfere with the cutting of the cutter 20.

[0023] Reference Figure 1-Figure 5The pressing plate structure 8 includes an upper pressing plate 804 and a hinge shaft 803. A plurality of elastic brackets 802 are fixedly connected to the bottom of the upper pressing plate 804. Two roller brackets 806 are fixedly connected to the bottom of the plurality of elastic brackets 802. The two roller brackets 806 are rotatably connected to the hinge shaft 803 and are hinged. A plurality of pressing plate rollers 805 are rotatably connected between the roller brackets 806. A bent plate 801 is fixedly connected to one side of one roller bracket 806. The hinge design of the bent plate 801, the elastic bracket 802 and the hinge shaft 803 on the pressing plate structure 8 can prevent the straw stacked in the equipment from being uneven and unable to be clamped due to different softness. The pressing plate rollers 805 on the pressing plate structure 8 cooperate with the feeding roller 6 to press the straw without affecting the movement of the straw toward the cutter 20.

[0024] The working principle of this feeding and clamping structure is as follows: an appropriate amount of straw is placed on the feeding roller 6, the cylinder 11 pushes the push rod 12 and the push frame 9 to move downward, driving the pressure plate structure 8 to press the straw below, starting the motor 13, and the output shaft 15 drives the transmission rod 16 to rotate through the belt, and the transmission rod 16 drives the cutter 20 to rotate and cut the straw. At the same time, the transmission rod 16 drives the gear shaft 17 to rotate through the gear, and the gear shaft 17 drives the half-tooth shaft 18 to rotate through the gear. The half-tooth shaft 18 is engaged with the gear on the threaded shaft 19 through the half gear 23 sleeved thereon, driving the threaded shaft 19 to rotate, and the rotation of the threaded shaft 19 drives the push plate 5 to advance toward the cutter 20.

[0025] Before the cutter 20 starts to cut the straw, the half gear 23 rotates to a position without teeth and does not mesh with the gear on the threaded shaft 19. At this time, the threaded shaft 19 does not rotate and does not drive the pusher plate 5 to move, and does not interfere with the action of the cutter 20 when cutting the straw. When the cutter 20 completes a cutting action, the position with teeth on the half gear 23 continues to mesh with the gear on the threaded shaft 19. At the same time, the threaded shaft 19 drives the pusher plate 5 to push the straw toward the cutter 20. Before the cutter 20 cuts, the half gear 23 rotates to a position without teeth, completing the action of separating from the gear on the threaded shaft 19, and cutting the straw reciprocatingly.

[0026] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0027] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
