[0002] Cotton bolls are the fruits of cotton plants and are an important stage in the life cycle of cotton. When the flowers of cotton plants are pollinated and fertilized, their ovaries begin to gradually swell and become young bolls. The initial shape of the cotton bolls resembles a small bell, hence the name. As time goes by, the cotton bolls gradually mature and grow larger, and their final shape resembles a peach, which is also called a cotton boll. The green boll stage of cotton is a period of rapid growth of fibers and seeds inside the bolls, and it is also the stage when the cotton bolls are most sensitive to environmental factors. The husks of green bolls are relatively hard, and it is time-consuming and laborious to peel off the husks to obtain samples such as husks, fibers, and embryos, which can easily cause sample degradation.

[0031] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0032] like Figure 1~Figure 4 As shown, this embodiment proposes a cotton boll sheller, including a first main body 1, a second main body 2, the second main body 2 is movably arranged or hingedly arranged relative to the first main body 1, the first main body 1 and the second main body 2 respectively have a first knife portion 101 and a second knife portion 201, the first knife portion 101 and the second knife portion 201 are arranged opposite to each other, and a pinching space 3 is formed therebetween, the first main body 1 and the second main body 2 also respectively have a third knife portion 102 and a fourth knife portion 202, the third knife portion 102 and the fourth knife portion 202 are arranged opposite to each other, and a shell prying space 4 is formed therebetween.

[0033] In this embodiment, the first body 1 and the second body 2 are the main structures of the cotton boll sheller, which can be made of high-strength lightweight alloy materials to ensure structural strength while reducing the overall weight, which is convenient for field operations. The first body 1 and the second body 2 can be long structures that are easy to operate by hand. One way is to connect them through a hinge to form a scissors-like structure that can rotate around the hinge axis to achieve an opening and closing action. The first knife part 101 and the second knife part 201 are located on one side of the hinge to form a pinching space 3. On the one hand, it can be used to cut off the connection between the cotton boll and the cotton branch, and on the other hand, it can be used to cut the peel of the cotton boll to open the cotton boll for subsequent shelling operations. The third knife part 102 and the fourth knife part 202 are located on the other side of the hinge to form a shell prying space 4. When the first body 1 and the second body 2 are closed or the opening is small, the third knife part 102 and the fourth knife part 202 are inserted into the opening of the cotton boll, and the cotton boll shell is pried open by the lever principle to release the internal cotton fiber. Anti-skid patterns can also be provided on the closed surfaces of the first body 1 and the second body 2, respectively, to increase the friction when in contact with the cotton bolls, prevent the cotton bolls from sliding during shelling, and improve the success rate of shelling.

[0034] In this embodiment, an electric drive mechanism can be added to drive the opening and closing of the first body 1 and the second body 2 by a motor to realize automatic shelling, thereby improving the working efficiency. The motor of the electric drive mechanism can adopt a brushless DC motor, which has the characteristics of high torque and low energy consumption and is suitable for long-term continuous work. At the same time, it is necessary to design a corresponding electronic control system that can automatically adjust the shelling force according to the size and hardness of the cotton boll to avoid damaging the cotton fiber due to excessive force. Pressure sensors are integrated on the first body 1 and the second body 2 to detect the position and state of the cotton boll to ensure the accuracy and safety of the shelling process.

[0035] In this embodiment, the automation of cotton boll shelling is realized through ingenious structural design, which can improve the efficiency and quality of cotton harvesting. Compared with traditional manual shelling or mechanical threshing, the sheller can quickly complete the shelling operation without damaging the cotton fiber, reduce the subsequent processing steps, reduce the production cost, and has simple operation steps, easy to carry, and has broad application prospects.

[0036] Furthermore, the first body 1 and the second body 2 both have a pressing portion 103 . The pressing portion 103 of the first body 1 is located on a side of the first body 1 away from the second body 2 . The pressing portion 103 of the second body 2 is located on a side of the second body 2 away from the first body 1 .

[0037] The pressing part 103 is designed to make it easier for the user to operate the device. The pressing part 103 is operated to change the shell prying space 4, improve the shelling efficiency, and ensure the operational consistency of the entire sheller design. The pressing part 103 is designed to be provided with ergonomic pressing parts 103 at the far end of the first body 1 and the second body 2, that is, on the side away from each other. These pressing parts 103 can usually be covered with soft materials to increase the comfort when holding, while providing a good grip and reducing hand fatigue. The operating principle is that the user can easily control the opening and closing between the two bodies by pressing the pressing part 103 on the first body 1 and the second body 2, so as to realize the pinching and prying operation of the cotton boll. This design makes the operation of the sheller more intuitive and convenient, and even users with weak physical strength can use it effectively. In order to ensure the durability of the pressing part 103 and the smoothness of the operation, the skeleton of the pressing part 103 is made of high-strength material, and the outer layer is made of wear-resistant soft material to ensure that the hand feel is still good after long-term use. In addition, the design of the pressing portion 103 takes into account the natural bending angle of the hand, thereby minimizing the stress on the wrist during operation.

[0038] Furthermore, the pressing portion 103 is located beside the pry shell space 4 .

[0039] In this embodiment, special attention is paid to the relative position of the pressing part 103 and the shell prying space 4 to improve the convenience of operation and the efficiency of shelling. The layout is optimized: on the first body 1 and the second body 2, the pressing part 103 is carefully designed next to the shell prying space 4. Such a layout ensures that when the user is operating, the fingers can naturally transition from the pressing part 103 to the shell prying space 4, so as to achieve the continuity and smoothness of the shelling operation. The operation logic is more convenient: the user first controls the opening and closing of the first body 1 and the second body 2 through the pressing part 103, positions the cotton boll in the pinching space 3 for preliminary cutting, and then, without moving the hand significantly, the cotton boll can be sent into the shell prying space 4, and the shelling is completed using the third knife part 102 and the fourth knife part 202. This layout simplifies the operation process, reduces the moving distance of the hand, and improves the shelling speed. Improved ergonomics: The close layout of the pressing part 103 and the shell prying space 4 fully considers the ergonomic principles, ensuring that the operator's hand and wrist movements are more natural during the shelling process, reducing muscle fatigue caused by repetitive movements.

[0040] Furthermore, the pressing portion 103 is an integral structure or a separate structure with the first body 1 and the second body 2 .

[0041] In this example, the pressing part 103 is set as an integrated structure to increase the stability of the structure and reduce problems caused by loose connections. As for the split structure, if the pressing part 103 is damaged, only this part needs to be replaced without replacing the entire sheller, which reduces maintenance costs and can reduce maintenance and replacement of equipment.

[0042] Furthermore, it also includes a hinge axis 8, and the second body 2 is hinged to the first body 1 through the hinge axis 8. The first knife portion 101 and the second knife portion 201 are respectively located at the ends of the first body 1 and the second body 2 away from the hinge axis 8, and the distance between the first knife portion 101 and the second knife portion 201 gradually decreases from close to the hinge axis 8 to away from the hinge axis 8.

[0043] In this example, the second body 2 is connected to the first body 1 by the hinge shaft 8, so that both bodies can be rotated by the hinge shaft 8, which reduces the difficulty of use for the operator and improves the adaptability of the sheller to cutting cotton bolls of different sizes. The first knife part 101 and the second knife part 201 are far away from the end of the hinge shaft 8, and the distance between the knife parts gradually decreases from the hinge shaft 8 to the outside, that is, the first knife part 101 and the second knife part 201 are designed to gradually tilt closer to each other to form a wedge-shaped structure. This design utilizes the principle of leverage, so that during the closing process, the knife part can exert increasing pressure on the cotton boll, thereby more effectively cutting and peeling off the cotton boll shell, facilitating positioning and cutting, and improving the shelling efficiency.

[0044] Furthermore, both the first blade portion 101 and the second blade portion 201 have a first blade edge 104 , and the first blade edge 104 is arc-shaped.

[0045] In this example, both the first blade 101 and the second blade 201 have a first blade 104, and are designed to be arc-shaped. The design of the arc-shaped blade can better fit the natural contour of the cotton boll, and cut the connection part with the cotton boll rod, reducing the damage to the inside of the cotton boll during the cutting process, ensuring that the cutting of the cotton boll during the shelling process is more accurate, and improving the cutting efficiency. The blades of the first blade 101 and the second blade 201 are designed to be arc-shaped. This design imitates the natural action of human hand shelling, and can better fit the curve of the connection part between the cotton boll and the cotton boll rod, so as to apply more uniform pressure during the shelling process and reduce the damage to the cotton fiber. The shelling efficiency is improved. When the arc-shaped blade cuts into the cotton boll, it can cut along the natural contour of the cotton boll, reducing invalid cutting actions and improving the accuracy and efficiency of shelling. In addition, the arc-shaped blade can also guide the cotton boll into the shelling space 4 to a certain extent, simplifying the shelling process.

[0046] Furthermore, the two third blade parts 102 are arranged in parallel with each other, and the two fourth blade parts 202 are arranged in parallel with each other. The arrangement direction of the two third blade parts 102 is parallel to the length direction of the hinge shaft 8, and the arrangement direction of the two fourth blade parts 202 is parallel to the length direction of the hinge shaft 8.

[0047] In this example, based on Example 3, the third blade section 102 and the fourth blade section 202 are two blades arranged in parallel to each other, and are designed as double-row parallel blades. The third blade section 102 and the fourth blade section 202 are each composed of two blades arranged in parallel, and the arrangement direction of these blades is parallel to the length direction of the hinge shaft 8. This design increases the contact area with the cotton boll, making the shelling process more stable, reducing the shaking of the cotton boll during the shelling process, and improving the stability and efficiency of shelling. It can also better enable the blade to accurately cut the gap of the cotton boll. The parallel blades can support each other during the cutting process, improve the stability of the blade section, and reduce the blade offset caused by improper operation or irregular shape of the cotton boll. This setting increases the stability of the shelling space 4, improves the shelling efficiency and safety of use, and ensures the smooth progress of the shelling process.

[0048] The husking efficiency and stability are improved: the double-row parallel blades form a stable "husking channel" in the husking space 4. When the cotton bolls are squeezed into this channel, the blades on both sides can act on different parts of the cotton bolls at the same time, which not only accelerates the husking process, but also ensures the positioning of the cotton bolls during the husking process, avoiding the problems of incomplete husking or damage to cotton fibers.

[0049] Furthermore, the third blade portion 102 and the fourth blade portion 202 are both flat-plate shaped and both have a second blade edge 105 , and the second blade edge 105 is straight-line shaped or arc-shaped.

[0050] In this example, the third blade 102 and the fourth blade 202 are flat-plate-shaped and both have a second blade 105, which is straight or curved. The flat-plate blade design is usually safer than a sharp blade, reducing the risk of accidental cutting. This design can better cut the cotton bolls and increase the flexibility and functionality of the sheller. At the same time, the larger blade area also helps to disperse the stress during cutting and extend the service life of the blade.

[0051] Further, if Figure 3 , Figure 4 As shown, the first body 1 has an arc-shaped guide groove 106, and the end of the arc-shaped guide groove 106 has a clamping groove portion 107. The second body 2 has a bending guide groove 203, and also includes a clamping column 5, which slides in the arc-shaped guide groove 106 and is slidably set in the bending guide groove 203, and the clamping column 5 has an operating portion 501.

[0052] In this embodiment, a clamping column 5 is also designed. An arc-shaped guide groove 106 is provided on the first body 1, and a clamping groove portion 107 is provided at the end thereof; a matching bending guide groove 203 is provided on the second body 2. The clamping column 5 can slide in the arc-shaped guide groove 106 and the bending guide groove 203. When the clamping column 5 slides to the clamping groove portion 107 and is stuck, the first body 1 and the second body 2 reach a closed state, ensuring the stability and safety of the sheller during the shelling process. An operating portion 501 is provided at one end of the clamping column 5, and the user can manually control the sliding of the clamping column 5 in the guide groove 106 through the operating portion 501 to realize the use state and the closed state of the sheller.

[0053] Further, if Figure 4 As shown, it also includes a movable adjustment plate 6, which is slidably set in the arc guide groove 106 and is located at an end away from the slot portion 107. After the movable adjustment plate 6 moves, the length of the arc guide groove 106 is changed, and the locking bolt 7 is used to lock the movable adjustment plate 6 in the arc guide groove 106.

[0054] In this embodiment, a movable adjustment plate 6 is also designed. A slidable movable adjustment plate 6 is set in the arc-shaped guide groove 106 of the first body 1. The adjustment plate is located at one end away from the slot portion 107. By moving the position of the adjustment plate 6, the effective length of the arc-shaped guide groove 106 can be changed, and then the relative movement stroke of the first body 1 and the second body 2 can be adjusted to achieve the adjustability of the shelling force and the shelling depth. Among them, the locking bolt 7 is used to fix the movable adjustment plate 6 at any position in the arc-shaped guide groove 106. Once the stroke is adjusted, the user can tighten the locking bolt 7 to firmly fix the movable adjustment plate 6 to ensure the stability and consistency of the shelling process.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
