Obviously, the embodiments described 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.

[0024] like Figures 1 to 4As shown, the utility model provides a high-efficiency shelling machine for cottonseed hulls, including a shelling box 1, characterized in that: the inner surface of the shelling box 1 is rotatably connected to two shelling rollers 6, one end of the two shelling rollers 6 passes through the shelling box 1 and is fixedly connected to a gear 3, the two gears 3 are meshed with each other, one end of the shelling box 1 is fixedly connected to a first motor 4, the output end of the first motor 4 is fixedly connected to one of the gears 3, and a screening mechanism 8 is provided directly below the two shelling rollers 6. Through the rotational connection of the two shelling rollers 6, the meshing of the gears 3 and the drive of the first motor 4, an efficient shelling operation of the cottonseed hulls is realized, and a screening mechanism 8 is provided below the shelling rollers 6, which can timely screen and process the shelled material, thereby improving the overall work efficiency and reducing the workload of subsequent manual screening.

[0025] Specifically, the outer surfaces of the two shelling rollers 6 are engraved with textures, the texture of one shelling roller 6 is spiral, and the outer texture of the other shelling roller 6 is straight, which can enhance the friction and gripping force on the cottonseed shells, so that the cotton seeds and cottonseed shells are better separated, further improving the shelling effect and ensuring the shelling quality.

[0026] like Figures 1 to 4 As shown, two inclined plates 5 are fixedly connected to the inner surface of the shelling box 1. The two inclined plates 5 are respectively located above the two shelling rollers 6, and can guide the cottonseed hulls and cotton seeds to smoothly enter between the shelling rollers 6 for shelling operations.

[0027] Furthermore, the screening mechanism 8 includes a second motor 82, which is fixedly connected to the shelling box 1. The output end of the second motor 82 passes through the shelling box 1 and is fixedly connected to the cam 81. The inner surface of the shelling box 1 is fixedly connected to two fixed plates 84, one of which is provided with a through groove 83 for cooperating with the cam 81. The corresponding ends of the two fixed plates 84 are slidably connected to a vibration frame 87. The outer surface of the cam 81 fits into one end of the vibration frame 87. A plurality of springs 85 are fixedly connected to both sides of the lower part of the vibration frame 87. The plurality of springs 85 are respectively fixedly connected to the two fixed plates 84, providing a reliable vibration source for the subsequent screening work of the screen 90, thereby ensuring the continuous and effective progress of the screening work.

[0028] like Figures 1 to 4 As shown, a screen frame 86 is provided on the inner surface of the vibration frame 87, a screen 90 is fixedly connected to the inner surface of the screen frame 86, two guide grooves 88 are provided on the inner surface of the vibration frame 87, and a guide bar 89 is fixedly connected to the outer surface of the screen frame 86 for use with the two guide grooves 88, which can fix the screen 90 and facilitate the removal of the internal cottonseed shells after the screening is completed.

[0029] It is worth noting that a collecting box 7 is placed on the lower inner wall of the shelling box 1. The collecting box is located directly below the sieve rack 86 7. A box door 2 is rotatably connected to one side of one end of the shelling box 1. The collecting box 7 is used to collect the screened cotton seeds. The design of the box door 2 facilitates the removal of the collecting box 7 or the sieve rack 86.

[0030] like Figures 1 to 4 As shown, the mesh aperture size of the screen 90 in the shelling box 1 is designed to be larger than the size of the cotton seeds and smaller than the size of the cottonseed hulls, so that during the screening process, the cotton seeds can pass through the screen 90, while the cottonseed hulls are intercepted by the screen 90, which can accurately achieve the separation of cotton seeds and cottonseed hulls, ensuring that only cotton seeds pass through the screen 90 into the collecting box 7, while the cottonseed hulls remain above the screen 90, thereby improving the screening accuracy and enhancing the product quality.

[0031] The first motor 4 and the second motor 82 are prior art and will not be described in detail. Furthermore, the present invention also includes a power supply, a controller, and a switch, which are not key technical aspects of the present invention and will not be described in detail. The wiring diagrams for the motors in the present invention are common knowledge in the art, and their operating principles are well-known technology. The appropriate model should be selected based on actual use, so the control methods and wiring arrangements for the motors will not be explained in detail.

[0032] Working principle and process: When shelling is required, the first motor 4 is started first, and the first motor 4 drives the gear 3 connected thereto to rotate. Since the two gears 3 are meshed with each other, the two shelling rollers 6 are driven to rotate in opposite directions in the shelling box 1. The cottonseed hull raw material is placed in the shelling box 1. The texture of the outer surface of the shelling roller 6 is one spiral and the other straight, which can increase the friction and gripping force with the cottonseed hull. When the cottonseed hull enters between the two shelling rollers 6 rotating in opposite directions, the cottonseed and the cottonseed hull are separated under the squeezing and friction of the shelling rollers 6, and the shelling operation is completed. The shelled material falls off The cotton seeds fall onto the screening mechanism 8 below, and the second motor 82 in the screening mechanism 8 is started. The output end of the motor drives the cam 81 to rotate. The cam 81, in cooperation with the fixed plate 84 and the spring 85, causes the vibration frame 87 to vibrate. During the vibration process, the cotton seeds can pass through the screen 90, while the cotton seed shells are intercepted by the screen 90. The cotton seeds passing through the screen 90 fall into the collecting box 7 located just below the screen frame 86, completing the collection of the cotton seeds. When the cotton seeds and cotton seed shells need to be taken out, the door 2 of the shelling box 1 is opened, the collecting box 7 is taken out, and then the screen 90 is taken out through the guide bar 89 and the guide groove 88.
