Specific Embodiments

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model. Embodiment

[0030] Refer to Figures 1 - 5, the present utility model provides a technical solution: a straw feed crushing device, including a housing 1 and a crushing mechanism 3. A partition plate 2 is stably installed inside the housing 1. The crushing mechanism 3 includes a pressure roller 31. The pressure roller 31 is arranged on one side of the partition plate 2, and the pressure roller 31 is rotatably connected to the partition plate 2. A driving wheel 32 is rotatably installed inside the housing 1, and a convex block 321 is installed on the outer surface of the driving wheel 32. A crushing knife 33 is arranged outside the housing 1 for crushing straw.

[0031] In a preferred embodiment, a control motor 4 is installed inside the housing 1. The output end of the control motor 4 is fixedly installed with a transmission shaft 5. One end of the transmission shaft 5 is fixedly connected to a round block 6, and the crushing knife 33 is stably installed on the outer surface of the round block 6. The device realizes the crushing of straw through the rotation of the crushing knife 33. Therefore, a control motor 4 is installed inside the housing 1, and the crushing knife 33 is arranged at the output end position of the control motor 4 to drive the crushing knife 33 to rotate rapidly and cut the straw to obtain straw feed.

[0032] In a preferred embodiment, a support plate 7 is stably installed inside the housing 1, and the control motor 4 is stably installed on the upper surface of the support plate 7 for the stable operation of the control motor 4. Heat dissipation holes 8 are opened on the outer surface of the housing 1, and the positions of the heat dissipation holes 8 are set corresponding to the position of the control motor 4 for dissipating heat from the control motor 4. The device installs the control motor 4 inside the housing 1. To ensure the stable operation of the control motor 4, a support plate 7 is installed inside the housing 1, and the control motor 4 is installed on the support plate 7 through bolts, which can ensure the stable use of the control motor 4. Moreover, the heat generated by the control motor 4 during operation will also be discharged from the position of the heat dissipation holes 8 to dissipate heat from the control motor 4 in time, facilitating use.

[0033] To facilitate the processing of straw, a rectangular frame 9 is fixedly installed inside the housing 1, and a conveyor belt 10 is installed inside the rectangular frame 9. A number of cushion wheels 11 are installed in the middle of the conveyor belt 10 and are evenly arranged inside the rectangular frame 9. During actual use, straw can be placed on the conveyor belt 10. Through the rotation of the conveyor belt 10, the straw will be moved to the position of the pressure roller 31. The straw is extruded by the pressure roller 31 to be scattered, reducing the strength of the straw, so that the crushing knife 33 can quickly cut the straw, reducing the wear on the crushing knife 33 and extending the service life of the crushing knife 33 to meet the use requirements.

[0034] This device installs the crushing knife 33 outside the housing 1. When crushing straw, to avoid the risk of the crushing knife 33 breaking and flying out, a protective mechanism 12 is also installed on the housing 1. The protective mechanism 12 includes an arc-shaped cover 121, a tension spring 122, and a plugging pin 123. A rectangular block 13 is fixedly installed at the top of the housing 1, and the arc-shaped cover 121 is rotatably connected at a position on one side surface of the rectangular block 13. A sleeve frame 14 is installed on the outer surface of the arc-shaped cover 121. A tension spring 122 is installed at the top of the housing 1, and one end of the tension spring 122 is connected to the outer surface of the arc-shaped cover 121. A plug board 15 is also fixedly installed on the outer surface of the housing 1, and a plugging hole 16 is opened on the upper surface of the plug board 15. The plugging pin 123 is plugged into the interior of the plugging hole 16 for limiting the arc-shaped cover 121.

[0035] During actual use, the crushing knife 33 will become dull after long-term use, resulting in the inability of the crushing knife 33 to cut the straw. At this time, the crushing knife 33 needs to be replaced. At this time, the plugging pin 123 is pulled out from the interior of the plug board 15, and the arc-shaped cover 121 is flipped. The arc-shaped cover 121 is rotated upward, and the crushing knife 33 can be exposed. When the arc-shaped cover 121 is rotated upward, it will be pulled by the tension spring 122 and will not rotate downward, avoiding affecting the replacement of the crushing knife 33. The staff can conveniently replace the crushing knife 33, avoiding the arc-shaped cover 121 from affecting the operation of the staff.

[0036] Specifically, the working process or working principle of a straw feed crushing device is as follows: Currently, the method of crushing straw is mostly to place the straw into a crushing box for processing. A cutting knife is installed inside the crushing box. When the straw is placed into the processing box, the straw can be crushed. However, in actual operation, the complete straw has a certain hardness. When the blade crushes the straw, when the blade encounters harder straw, it will forcibly cut, and at this time, the blade is likely to break, which not only affects the normal use of the equipment but also poses a danger. Therefore, this device is designed to solve this problem.

[0037] This device can first fracture the straw to make it loose, and then crush it, which reduces the wear of the crushing knife 33, avoids the fracture of the crushing knife 33 and the occurrence of danger, and at the same time ensures the normal use of the equipment and continuously crushes the straw. The specific operation is as follows: Connect to an external power supply and turn on the conveyor belt 10. The usage method of the conveyor belt 10 is already an existing technology, so it will not be elaborated here. Place the straw on the conveyor belt 10, and the conveyor belt 10 will drive the straw to move. The straw will be moved to the position of the pressure roller 31. Since the distance between the pressure roller 31 and the conveyor belt 10 is less than the diameter of the straw, the straw will be rolled under the pressure roller 31 during the conveying process. The straw can be extruded by the pressure roller 31 to fracture and loosen it. As the straw is continuously conveyed, it will continuously pass through the positions of multiple pressure rollers 31. By extruding the straw with the pressure roller 31, the straw can be fully fractured and dispersed, reducing the strength of the straw.

[0038] When the straw moves to the position of the driving wheel 32, it will rotate through the driving wheel 32 to drive the straw to move and extend the straw out of the inside of the housing 1. At the same time, the crushing knife 33 will continuously rotate under the drive of the control motor 4. When the straw extends out of the inside of the housing 1, it will be crushed by the crushing knife 33 to realize the cutting and crushing of the straw in order to obtain crushed feed.

[0039] When this device is in use, to improve safety, the arc-shaped cover 121 will be covered at one end of the housing 1, and the crushing knife 33 will be arranged inside the arc-shaped cover 121 to avoid danger and protect the staff.

[0040] The crushing knife 33 will become blunt after long-term use, resulting in the inability of the crushing knife 33 to cut the straw. At this time, the crushing knife 33 needs to be replaced. At this time, pull out the plug pin 123 from the inside of the plug board 15 and turn over the arc-shaped cover 121. Rotate the arc-shaped cover 121 upward, and the crushing knife 33 can be exposed. When the arc-shaped cover 121 rotates upward, it will be pulled by the tension spring 122 so that it will not rotate downward, avoiding affecting the replacement of the crushing knife 33. The staff can conveniently replace the crushing knife 33. After replacing the crushing knife 33, the crushing knife 33 can be restored to its original state. Cover the crushing knife 33 with the arc-shaped cover 121, put the sleeve frame 14 on the plug board 15, and insert the plug pin 123 into the inside of the plug hole 16 to position the arc-shaped cover 121, so that the arc-shaped cover 121 can be stably used.

[0041] It should be noted that the control motor 4 is a device or equipment existing in the prior art, or a device or equipment that can be realized by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so it will not be elaborated in detail.
