[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] An economical and efficient stubble-cutting machine includes a stubble-cutting body 1, a fixed sleeve 6 fixedly connected to the top of the stubble-cutting body 1, a rotating box 5 arranged on the rear side of the fixed sleeve 6, a power mechanism 9 arranged on the left side of the stubble-cutting body 1, a transmission mechanism 8 arranged on the top of the stubble-cutting body 1, a plurality of stubble-cutting blades 2 rotatably connected inside the stubble-cutting body 1, and a power wheel 7 arranged on the left side of the stubble-cutting body 1.

[0027] The transmission mechanism 8 includes a fixed shaft 801, a connecting sprocket 802, a chain 803, two connecting parts 804, a transmission shaft 805, and an annular groove 806. The connecting sprocket 802 is bolted to the surface of the fixed shaft 801. The front side of the front connecting part 804 is fixedly connected to the rear side of the fixed shaft 801, and the rear side of the rear connecting part 804 is fixedly connected to the front side of the transmission shaft 805. The fixed shaft 801 is movably inserted into the interior of the transmission shaft 805. The two connecting parts 804 are engaged. The chain 803 meshes with the connecting sprocket 802. The transmission shaft 805 is rotatably connected to the interior of the fixed sleeve 6. The annular groove 806 is formed inside the transmission shaft 805.

[0028] In this embodiment: the power output shaft of the diesel engine is connected to the power wheel 7. The rotation of the power wheel 7 drives the fixed disk 903 and the gear ring 902 to rotate synchronously. The gear ring 902 drives the chain 803 that meshes with it to move. The chain 803 drives the sprocket 802, which in turn causes the fixed shaft 801 to rotate. The fixed shaft 801 transmits the rotation to the transmission shaft 805 through the snap-fit ​​connector 804. The transmission shaft 805 is rotatably connected inside the fixed sleeve 6. The spring between the two provides assistance for power control. The transmission shaft 805 drives the stubble-cutting blade 2, which is made of 65Mn steel and has undergone specific heat treatment and is arranged in a 360-degree spiral, to rotate, cutting and crushing the stubble to complete the stubble-cutting operation. When controlling the power on and off, the lever 3 is moved to drive the rotating column 15 and the fork 14 to rotate. The fork 14 moves the ring of the transmission shaft 805. The groove 806 allows the drive shaft 805 to move against the spring force, disengaging the coupling 804 to cut off power; releasing the lever 3 allows the drive shaft 805 to return to its original position under the action of the spring, and the coupling 804 re-engages to restore power. In addition, the tension wheel 19 is installed on the shaft 21 of the support frame 11, and the shaft 21 slides in the slide groove 20. Rotating the nut 10 on the rear side of the support frame 11 can adjust the position of the tension wheel 19, ensuring good meshing between the chain 803 and the gear ring 902 and the coupling sprocket 802. The stubble shredder body 1 is made of lightweight material, small in size and light in weight, and can be efficiently matched with the 190 diesel engine. It solves the problems of existing stubble shredders on the market, such as large size and heavy weight, complicated installation and disassembly, low efficiency of power transmission system, easy slippage of belt 13, easy damage to the main shaft and gears, poor stubble shredding effect, and the requirement for high power of the matching main unit.

[0029] Specifically, such as Figure 3 As shown, the power mechanism 9 includes several screws 901, a gear ring 902, a fixed plate 903, and a mounting hole 904. The mounting hole 904 is opened inside the fixed plate 903. The side of the screw 901 near the mounting hole 904 passes through the mounting hole 904 and is threadedly connected to the inside of the power wheel 7. The rear side of the gear ring 902 is fixedly connected to the front side of the fixed plate 903. The chain 803 meshes with the gear ring 902.

[0030] Specifically, such as Figure 3As shown, a support plate 17 is fixedly connected to the top of the fixed sleeve 6, a rotating column 15 is provided on the left side of the support plate 17, and a shift fork 14 is fixedly connected to the right side of the rotating column 15. The surface of the shift fork 14 is in contact with the inner wall of the annular groove 806.

[0031] Specifically, such as Figure 3 As shown, a support sleeve 16 is fixedly connected to the left side of the support plate 17, and the rotating column 15 is rotatably connected inside the support sleeve 16.

[0032] Specifically, such as Figure 3 As shown, a limiting groove 18 is provided inside the support plate 17, and a lever 3 is rotatably connected to the top of the rotating column 15. The side of the lever 3 near the rotating column 15 is rotatably connected to the rotating column 15, and the lever 3 is movably connected inside the limiting groove 18.

[0033] In this embodiment, the gear ring 902 and the fixed plate 903 are stably connected to the drive wheel 7 by screws 901, which facilitates the operation of the chain 803. The rotating column 15 is rotatably connected inside the support sleeve 16, which facilitates the rotation of the rotating column 15. Moving the lever 3 can drive the shift fork 14 to rotate, which facilitates the movement of the drive shaft 805, causing the two couplings 804 to separate and cut off the power output.

[0034] Specifically, such as Figure 1 and Figure 5 As shown, a support frame 11 is fixedly connected to the left side of the stubble culling machine body 1. A tension wheel 19 is provided on the front side of the support frame 11. A sliding groove 20 is provided inside the support frame 11. A shaft 21 is slidably connected inside the sliding groove 20. A nut 10 is provided on the rear side of the support frame 11. The tension wheel 19 is rotatably connected to the surface of the shaft 21. The nut 10 is threaded onto the surface of the shaft 21. The tension wheel 19 meshes with the chain 803.

[0035] Specifically, such as Figure 1 As shown, a belt 13 is movably mounted on the surface of the power wheel 7. There are two belts 13. A handle 4 is fixedly connected to the right side of the fixed sleeve 6. A connecting plate 12 is fixedly connected to the top and bottom of the left side of the stubble shaving machine body 1.

[0036] Specifically, such as Figure 1 As shown, the stubble-cutting blade 2 is made of 65Mn steel. The stubble-cutting blade 2 has undergone specific heat treatment and is arranged in a 360-degree spiral pattern. The stubble-cutting machine body 1 is made of lightweight material.

[0037] In this embodiment: To ensure the transmission efficiency and stability of the chain 803, a tensioner 19 is provided. The tensioner 19 is mounted on the shaft 21 on the front side of the support frame 11. The shaft 21 slides within the groove 20 inside the support frame 11. By rotating the nut 10 on the rear side of the support frame 11, the position of the shaft 21 within the groove 20 can be adjusted, thereby adjusting the tension of the chain 803 by the tensioner 19. This ensures that the chain 803 always maintains good meshing with the gear ring 902 and the sprocket 802. By driving the belt 13 through the external diesel engine power take-off shaft, the belt 13 can drive the drive wheel 7. The rotating blades provide power to the stubble-removing machine body 1. By holding the handle 4, the stubble-removing machine body 1 can be easily kept stable. The stubble-removing blades 2 are made of 65Mn steel and have undergone specific heat treatment to achieve suitable hardness. They are arranged in a 360-degree spiral pattern inside the stubble-removing machine body 1. When the stubble-removing machine is working in the field, the rotating stubble-removing blades 2 cut and crush the stubble after the crops are harvested to complete the stubble removal work. Because the stubble-removing machine body 1 is made of lightweight materials, it is small in size and light in weight while ensuring the effectiveness and ease of operation. It can be matched with a 190 diesel engine to work normally and efficiently, reducing fuel consumption and improving economy.

[0038] Working principle: The power wheel 7 serves as the power input end, driven by the external diesel engine power output shaft. The fixed disc 903 is fixedly connected to the power wheel 7 via screws 901. The gear ring 902 is installed on the front side of the fixed disc 903. When the power wheel 7 rotates, it drives the fixed disc 903 and the gear ring 902 to rotate synchronously. As the gear ring 902 rotates, the chain 803, which meshes with the gear ring 902, moves accordingly. The chain 803 simultaneously meshes with the engaging sprocket 802, thereby driving the engaging sprocket 802 to rotate. The engaging sprocket 802 is fixed on the fixed shaft 801, driving the fixed shaft 801 to rotate. The fixed shaft 801 is movably inserted into the drive shaft 805, and the front and rear engaging parts 804 are respectively connected to the fixed shaft 801 and the drive shaft 805. Under normal operating conditions, the two... The fixed shaft 801 is connected to the drive shaft 805 via the coupling 804. The drive shaft 805 is rotatably connected inside the fixed sleeve 6, and a spring is installed between the drive shaft 805 and the inside of the fixed sleeve 6. The rotation of the drive shaft 805 drives the stubble-cutting blade 2 connected to it to rotate inside the stubble-cutting machine body 1. The stubble-cutting blade 2 is made of 65Mn steel, which has undergone specific heat treatment to achieve suitable hardness. It is arranged in a 360-degree spiral pattern inside the stubble-cutting machine body 1. When the stubble-cutting machine is working in the field, the rotating stubble-cutting blade 2 cuts and crushes the stubble after crop harvesting to complete the stubble-cutting work. When it is necessary to control the on / off of power transmission, it is achieved by operating the lever 3, which is rotatably connected to the top of the rotating column 15. The rotating column 15 is rotatably connected inside the support sleeve 16, which is fixed to the left side of the support plate 17. Moving the lever 3 backward causes the rotating column 15 to rotate, and the shift fork 14 on the right side of the rotating column 15 rotates accordingly. The shift fork 14 makes active contact with the inner wall of the annular groove 806 inside the drive shaft 805. When the shift fork 14 rotates, it moves the annular groove 806, causing the drive shaft 805 to move axially against the spring force, thereby moving the rear coupling 804 and separating the two couplings 804, cutting off power transmission. When the lever 3 is released, the drive shaft 805 returns to its original position under the action of the spring, and the two couplings 804 re-engage, restoring power transmission. During operation, to ensure the transmission efficiency and stability of the chain 803, a tension wheel 19 is installed. The shaft 21, mounted on the front side of the support frame 11, slides within the groove 20 inside the support frame 11. By rotating the nut 10 on the rear side of the support frame 11, the position of the shaft 21 within the groove 20 can be adjusted, thereby adjusting the tension of the tension wheel 19 on the chain 803. This ensures that the chain 803 maintains good meshing with the gear ring 902 and the sprocket 802. The stubble wiping machine body 1 is made of lightweight materials, ensuring both effectiveness and ease of operation. It is small in size and light in weight, allowing it to work efficiently with a 190 diesel engine, reducing fuel consumption and improving economy. This solves the problems of existing stubble wiping machines on the market, such as large size, heavy weight, complex installation and disassembly, low power transmission system efficiency, easy slippage of the belt 13, and easy damage to the main shaft and gears.The problem lies in the poor stubble-crushing effect, requiring a high-power main unit.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
