[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only some embodiments, not all embodiments. Based on the embodiments described, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0016] Example 1: Please see Figure 1-4 A flaxseed dehulling and extraction device includes a fixed base 1, a dehulling box 2 fixedly installed on the upper part of the fixed base 1, a dehulling extrusion roller 6 rotatably installed inside the dehulling box 2, a guide plate 5 fixedly installed inside the dehulling box 2, a first motor 7 fixedly installed on the outer side of the dehulling box 2, fixed plates 3 fixedly installed on the left and right sides of the dehulling box 2, threaded holes are opened on the surface of the fixed plates 3, threaded rods 8 are threadedly installed on the inner wall of the threaded holes, an mounting plate 10 is rotatably installed on one end of the threaded rods 8 facing the inside of the dehulling box 2, a spring 11 is fixedly installed on the surface of the mounting plate 10, a cleaning plate 12 is fixedly installed on one end of the spring 11, a vibration motor 13 is fixedly installed on the outer side of the cleaning plate 12, a separation box 16 is fixedly installed at the bottom of the dehulling box 2, a negative pressure suction channel 17 is installed on the outer side of the separation box 16, and a feed inlet is opened at the upper part of the dehulling box 2.

[0017] Specifically, flaxseed enters through the feed inlet and is guided by the guide plate 5 between the hulling and pressing rollers 6 for hulling. By rotating the threaded rod 8, the position of the mounting plate 10 can be adjusted, thereby adjusting the distance between the cleaning plate 12 and the hulling and pressing rollers 6 to ensure cleaning effect. The vibration motor 13 is started to drive the cleaning plate 12 to vibrate, effectively removing residual broken shells and impurities. The mounting plate 10 is connected to the outside of the hulling box 2 by bolts, so that the cleaning plate 12 and the vibration motor 13 can be easily disassembled for maintenance or replacement. The hulled flaxseed falls into the separation box 16, and the light broken shells are separated from the heavy seeds by the negative pressure suction channel 17. The completely hulled flaxseed is discharged through the discharge guide plate 18. The negative pressure suction channel 17 is connected to the suction device to collect the broken shells to the external filtration system.

[0018] Preferably, there are three shelling extrusion rollers 6 arranged in an equilateral triangle, with gaps between adjacent shelling extrusion rollers 6 for material to pass through. The guide plate 5 is inclined between two shelling extrusion rollers 6. The outer ends of the three shelling extrusion rollers 6 are all equipped with transmission gears, which mesh with each other for transmission. The output end of the first motor 7 is fixedly connected to the outer end of the lowest shelling extrusion roller 6.

[0019] Specifically, the first motor 7 drives the lowest hulling extrusion roller 6 to rotate, and through gear meshing, drives the other two hulling extrusion rollers 6 to rotate synchronously, so as to achieve uniform extrusion and hulling of flax seeds. The outer side of the extrusion roller is provided with fine texture to enhance friction and ensure that the flax seeds are subjected to uniform force during the extrusion process, avoiding slippage or jamming.

[0020] Preferably, the surface of the cleaning plate 12 facing the shelling extrusion roller 6 has an arc-shaped structure, which is adapted to the outer surface of the shelling extrusion roller 6, and a cleaning brush is installed on the inner wall. A limit rod 9 is slidably installed on the outer side of the shelling box 2, and one end of the limit rod 9 is fixedly connected to the surface of the mounting plate 10.

[0021] Specifically, the arc-shaped cleaning plate 12 can closely fit the surface of the shell-removing extrusion roller 6, and together with the cleaning brush, effectively remove the adhering shell fragments and dust. The limiting rod 9 guides and stabilizes the movement of the mounting plate 10, preventing deviation during adjustment. Multiple sets of springs 11 are provided, and the high-frequency vibration generated when the vibration motor 13 is working allows the cleaning brush to vibrate fully, causing the debris adhering to the cleaning brush and plate to fall off, thereby maintaining the continuous cleaning ability of the cleaning plate 12 and ensuring long-term efficient operation.

[0022] Preferably, a baffle 14 is installed inside the shelling box 2, a collection box 15 is installed at the bottom of the shelling box 2, the bottom of the baffle 14 corresponds to the opening of the collection box 15, and a discharge guide plate 18 is installed at the bottom of the separation box 16.

[0023] Specifically, the baffle 14 is used to guide the broken shells and impurities that fall off during the shelling process into the collection box 15 to prevent them from flowing back to the discharge area. Then, there is a cleaning port on the outside of the collection box 15 to facilitate the periodic cleaning of accumulated impurities.

[0024] Working principle: During operation, flaxseed enters the hulling chamber 2 through the feed inlet and is guided by the guide plate 5 into the gap between three equilateral triangle-shaped hulling extrusion rollers 6. Driven by the first motor 7 and in conjunction with the rotation of gears, the three hulling extrusion rollers 6 rotate synchronously, using the fine texture on their surfaces to evenly extrude and hull the flaxseed. The hulled mixture then falls into the separation chamber 16 under gravity. Lighter hull fragments are sucked into the external filtration system by the airflow in the negative pressure suction channel 17, while heavier seeds fall along the separation chamber 16 and are discharged through the discharge guide plate 18. Simultaneously, the mounting plate 10 can be moved towards the descaling extrusion roller 6 by rotating the threaded rod 8, so that the cleaning brush on the cleaning plate 12 can be attached to the surface of the descaling extrusion roller 6. At the same time, the vibration motor 13 is started. Under the action of the high-frequency vibration force of the vibration motor 13, and with the setting of the spring 11, the cleaning brush will vibrate, which can effectively remove the residual debris attached to the cleaning brush and the plate, thereby achieving effective cleaning of the surface of the descaling extrusion roller 6, avoiding some residual debris from sticking to the surface of the descaling extrusion roller 6 and affecting the subsequent descaling effect, thus improving the descaling efficiency.

[0025] Example 2: Please see Figure 1-4 Preferably, a material cylinder 4 is fixedly installed on the upper part of the shelling box 2, a fixing frame 19 is fixedly installed on the upper part of the shelling box 2, a second motor 20 is installed on the fixing frame 19, a stirring rod 22 is fixedly installed at the output end of the second motor 20, a rotating blade 23 is fixedly installed at the lower end of the stirring rod 22, a feeding pipe 21 is fixedly installed at the bottom of the material cylinder 4, the rotating blade 23 is located inside the feeding pipe 21, and the feeding pipe 21 is connected to the inside of the shelling box 2.

[0026] Specifically, after the second motor 20 starts, it drives the stirring rod 22 and the rotating blade 23 to rotate. The rotating blade 23 stirs the material in the feeding pipe 21 to prevent the flax seeds from getting stuck during the feeding process and to ensure that the material enters the hulling box 2 evenly and continuously.

[0027] Preferably, a fixed frame 24 is fixedly installed on the outside of the feed pipe 21, a movable plate 26 is slidably installed inside the fixed frame 24, and a cylinder 25 is fixedly installed on the outside of the fixed frame 24. The telescopic end of the cylinder 25 is fixedly connected to the movable plate 26.

[0028] Specifically, cylinders 25 are set on both sides of the fixed frame 24. Cylinders 25 can drive the movable plate 26 to move. When the movable plate 26 moves outward, the feeding pipe 21 will be opened, and the flax seeds can fall smoothly into the shelling box 2. When the movable plate 26 moves inward, the feeding pipe 21 will be closed, which can accurately control the feeding speed and amount.

[0029] Working principle: Flaxseeds are fed into the feeding cylinder, and then the second motor 20 drives the stirring rod 22 and the rotating plate 23 to rotate, preventing the feeding pipe 21 from being blocked. At the same time, the cylinder 25 controls the movable plate 26 to adjust the opening and closing degree, thereby controlling the feeding speed and ensuring that the flaxseeds enter the shelling box 2 evenly and stably, avoiding insufficient shelling or equipment blockage due to excessive feeding, and improving the overall smoothness of operation and processing efficiency.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
