[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] The following description, in conjunction with the accompanying drawings, describes the straw crusher according to an embodiment of the present invention.

[0018] like Figures 1 to 8 As shown, the straw crusher of this utility model embodiment may include a crushing chamber 1, a transmission assembly 2, a crushing roller 3, and a limiting device 4.

[0019] Specifically, the top and bottom sides of the compaction chamber 1 are provided with an inlet 11 and an outlet 12, respectively, and the sides are provided with chutes 13.

[0020] It should be noted that a support leg 5 is also fixedly installed at the bottom of the crushing chamber 1, and the feed inlet 11 is located at the top of the side away from the crushing roller 3.

[0021] It can be understood that the grass can be put into the crushing chamber 1 through the feed inlet 11, and the grass that has been crushed by the crushing roller 3 will be discharged through the discharge outlet 12. The chute 13 provides movement space for the support rod 31 in the crushing roller 3 and limits its movement.

[0022] Specifically, the transmission assembly 2 includes a telescopic rod 21 and a mounting frame 22. The telescopic rod 21 is fixedly mounted on the compaction chamber 1, and the telescopic end of the telescopic rod 21 is inside the mounting frame 22 and connected to the compaction roller 3. The mounting frame 22 is fixedly mounted inside the compaction chamber 1, and limit grooves 221 are respectively opened on both sides of the mounting frame 22.

[0023] It should be noted that the mounting bracket 22 is also provided with a clearance groove 222. The limiting groove 221 includes: a first groove body 2211, a first arc-shaped groove 2212, a second arc-shaped groove 2213, a baffle 2214, and a first return spring 2215. The first groove body 2211 is a straight groove and is located below the clearance groove 222. The first arc-shaped groove 2212 and the second arc-shaped groove 2213 are located on the mounting bracket 22 on one side of the clearance groove 222. One end of the first arc-shaped groove 2212 and the second arc-shaped groove 2213 are respectively connected to the end of the first groove body 2211 near the feed inlet 11, and the first... The other ends of the first arc groove 2212 and the second arc groove 2213 are connected to each other. The end of the first arc groove 2212 connected to the first groove body 2211 is an arc groove, and the end connected to the second arc groove 2213 is a straight groove. The baffle 2214 is inclinedly hinged on the mounting bracket 22 at the connection between the first arc groove 2212 and the first groove body 2211, and the inclined end of the baffle 2214 abuts against the end of the first groove body 2211. One end of the first return spring 2215 is fixedly mounted on the mounting bracket 22, and the other end is connected to the baffle 2214. The support rod 31 is located at the top of the clearance groove 222.

[0024] A transmission block 211 is provided on the telescopic rod 21, wherein one end of the transmission block 211 is sleeved on the support rod 31, and the other end is hinged to the telescopic end of the telescopic rod 21.

[0025] It is understandable that when the telescopic rod 21 retracts, it can drive the support rod 31 to move along the slide groove 13 through the transmission block 211. When the support rod 31 moves, the slider 331 set on the feeding rod 33 will move along the first groove 2211 and the second arc groove 2213 under the influence of the baffle 2214. When the telescopic rod 21 extends or retracts, the slider 331 will move along the second arc groove 2213 and push open the baffle 2214 to enter the first groove 2211 to continue moving. When the slider 331 disengages from the baffle 2214, the baffle 2214 will be reset under the influence of the first return spring 2215.

[0026] Specifically, the rolling roller 3 includes: a support rod 31, a roller body 32, and a feeding rod 33. The support rod 31 is movably disposed inside the rolling chamber 1 and is located above the mounting frame 22. Both ends of the support rod 31 are respectively located in the sliding groove 13. The two roller bodies 32 are respectively fixedly disposed inside the support rod 31 and are respectively located on both sides of the mounting frame 22. The feeding rod 33 is L-shaped, with one end of each feeding rod 33 sleeved on the support rod 31 and the other end moving along the limiting groove 221.

[0027] It should be noted that a slider 331 is fixedly installed on the feeding rod 33. The slider 331 is fixedly installed on one side of the feeding rod 33 and is located in the first groove 2211.

[0028] Understandably, when the forage is added into the compaction chamber 1 through the feed inlet 11, the telescopic rod 21 retracts, which drives the support rod 31 to move along the limiting groove 221, thereby causing the slider 331 to move along the first groove 2211. When the slider 331 moves to the end of the first groove 2211, it will enter the second arc-shaped groove 2213 due to the influence of its baffle 2214. This will cause the feeding rod 33 to lift off the end away from the support rod 31, so that the feeding rod 33 passes over the forage piled up inside the compaction chamber 1. When the slider 331 moves to the end of the second arc-shaped groove 2213, the bottom of the feeding rod 33 away from the support rod 31 will abut against the bottom of the compaction chamber 1.

[0029] When the telescopic rod 21 extends or retracts, the slider 331 moves along the straight section of the first arc-shaped groove 2212, thereby pushing the straw towards the first trough 2211 via the feeding rod 33. When the slider 331 moves to the arc section of the first arc-shaped groove 2212, the feeding rod 33 is raised, thereby creating a gap with the bottom of the compaction chamber 1. At this time, if the slider 331 continues to move, it will only move the straw above the gap via the feeding rod 33, thereby achieving the purpose of spreading the straw evenly inside the compaction chamber 1.

[0030] Specifically, the limiting device 4 includes a flywheel 41, a guide rod 42, and a strip tooth 43. The flywheel 41 is respectively installed on both ends of the support rod 31 and is located on both sides of the compaction chamber 1. The guide rod 42 is fixedly installed on one side of the compaction chamber 1, and the flywheel 41 on the same side is sleeved on the guide rod 42. The strip tooth 43 is fixedly installed on the other side of the compaction chamber 1, and the flywheel 41 on the same side meshes with the strip tooth 43.

[0031] It should be noted that the flywheel 41 includes: a first ratchet 411, a second ratchet 412, a pawl 413, and a second return spring 414. The first ratchet 411 and the second ratchet 412 are respectively sleeved on both ends of the support rod 31 and are respectively provided with internal teeth 6 that match the pawls 413. The two pawls 413 are respectively hinged on both ends of the support rod 31 and respectively engage with the internal teeth 6 provided on the first ratchet 411 and the second ratchet 412. One end of the two second return springs 414 is fixed on the support rod 31, and the other end is respectively connected to the two pawls 413. The first ratchet 411 has an outer ring of teeth 4111, which mesh with the strip teeth 43. The second ratchet 412 is sleeved on the guide rod 42.

[0032] The lengths of the strip tooth 43 and the guide rod 42 are equal to those of the slide groove 13.

[0033] Understandably, when the support rod 31 moves toward the feed inlet 11, it will drive the first ratchet 411 and the second ratchet 412 to move together. The outer teeth 4111 of the first ratchet 411 mesh with the strip teeth 43, causing the first ratchet 411 to rotate counterclockwise. The counterclockwise rotation of the first ratchet 411 will drive the support rod 31 to rotate counterclockwise through the pawl 413 set on the support rod 31. This will cause the support rod 31 to drive the roller 32 to rotate, thus crushing the forage spread flat inside the crushing chamber 1.

[0034] When the support rod 31 moves in the opposite direction to the discharge port 12, the first ratchet 411 rotates clockwise. At this time, the first ratchet 411 no longer drives the support rod 31 to rotate, and the second ratchet 412, which moves along the guide rod 42, prevents the support rod 31 from rotating clockwise through the pawl 413 that engages with it. At this time, the roller body 32 no longer rotates, thereby pushing the forage that has been crushed at the bottom of the crushing chamber 1 to move towards the discharge port 12. This realizes the feeding of the forage.

[0035] In summary, the grass crusher according to the embodiments of this utility model can automatically flatten the grass, improve the grass crushing efficiency, and has high safety.
