The squeezing roller wrapped with a silicone coat has a certain elasticity, which can prevent the squeezing roller from excessively squeezing the watermelon seeds and causing the seeds to break. The adjustment component is used to change the elastic potential energy stored in the first spring in the initial state, so that when the rotating shaft works at different speeds, the distance between the squeezing roller driven away from the rotating shaft by the centrifugal force and the inner wall of the reactor is constant and equal, and the friction and squeezing between the squeezing roller and the watermelon seeds will not be reduced due to the speed adjustment, which will affect the cleaning quality. By setting a kneading component and utilizing the cooperation between the driving structure and the linkage structure, the squeezing roller can rotate when following the rotation axis, so as to knead the watermelon seeds placed between the inner wall of the reaction kettle and the squeezing roller. Moreover, under the effect of the uneven structure of the squeezing roller surface, the sticky substances adhering to the surface of the watermelon seeds can be more effectively removed, the outer skin of the seeds can be rubbed off, the seed cleaning efficiency is improved, and the germination rate of the watermelon seeds is improved. By setting up a water adding structure, water is continuously injected into the reactor along the tangential direction of the inner wall of the reactor using a water inlet pipe. The water injected into the reactor flows in a spiral along the inner wall of the reactor, driving the sticky substances removed from the surface of the watermelon seeds to flow out from the water outlet pipe.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0028] See also Figures 1 to 10 In an embodiment of the present invention, a cleaning device with controllable extrusion force includes a reactor 1, a rotating shaft 14 is installed on the reactor 1, a bidirectional extrusion structure is provided on the rotating shaft 14, and the bidirectional extrusion structure includes an extrusion roller 8 installed on the rotating shaft 14, and the rotation of the rotating shaft 14 can drive the rotating shaft 14 away from the rotating shaft 14; For details, please refer to Figure 1 , Figure 2 The rotating shaft 14 is fixedly connected to the output shaft of the motor fixedly installed on the reactor 1. When the motor is started, the rotating shaft 14 can drive the squeezing roller 8 to rotate in the reactor 1 to rub and clean the watermelon seeds in the reactor 1. The reactor 1 is provided with a water inlet pipe 7 and a water outlet pipe 6. A filter screen with a pore size smaller than that of the watermelon seeds is provided at the connection between the water inlet pipe 7 and the water outlet pipe 6 and the inner wall of the reactor 1 to prevent the watermelon seeds from entering the water inlet pipe 7 or the water outlet pipe 6; The water inlet pipe 7 can continuously inject water into the reactor 1 along the tangential direction of the inner wall of the reactor 1, so that the water injected into the reactor 1 spirally flows along the inner wall of the reactor 1, and the cross-section flowing in the reactor 1 presents a "U"-shaped structure, and finally flows out from the water outlet pipe 6; when injecting water, the watermelon seeds placed in the reactor 1 will adhere to the inner wall of the reactor 1 and follow the flow of water under the action of the water flow. In particular, the spirally flowing water injected into the reactor 1 is opposite to the rotation direction of the rotating shaft 14, so that the squeezing roller 8 can clean the watermelon seeds and inject water into the reactor 1.

[0029] The bidirectional extrusion structure further includes a fixed sleeve 15 fixedly connected to the rotating shaft 14, and the fixed sleeve 15 is symmetrically arranged in two groups, and a slide bar 17 is arranged in each group of the fixed sleeve 15, and a first spring 19 is slidably arranged on the slide bar 17, one end of the first spring 19 abuts against a moving part slidably arranged on the slide bar 17, and the other end abuts against a gasket of the end of the slide bar 17 immersed in the fixed sleeve 15, and a sleeve ring 9 is fixedly arranged on the end of the slide bar 17 away from the fixed sleeve 15, and the extrusion roller 8 is rotatably mounted on the sleeve ring 9; For details, please refer to Figure 3 The above-mentioned rotating device is installed on the sleeve ring 9 and can rotate relative to the sleeve ring 9. In particular, the outer wall of the squeezing roller 8 is wrapped with a layer of silicone pad. The squeezing roller 8 wrapped with the silicone coat has a certain elasticity, which can prevent the squeezing roller 8 from excessively squeezing the watermelon seeds and causing the seeds to break.

[0030] Specifically, in the initial state, the moving member is away from the rotating shaft 14 and is located at the end of the through slot 16 provided on the fixed sleeve 15. The first spring 19 is in a compressed state. The first spring 19 in the compressed state can push the end of the slide bar 17 away from the sleeve ring 9 to abut against the bottom of the fixed sleeve 15. At this time, the distance between the squeezing roller 8 and the rotating shaft 14 is the smallest, and the distance between the squeezing roller 8 and the inner wall of the reactor 1 is the largest. When it is necessary to clean the watermelon seeds, first pour the watermelon seeds to be cleaned into the reactor 1, then start the motor, and the motor output shaft drives the rotating shaft 14 to rotate continuously in the same direction. The centrifugal force generated during the rotation of the rotating shaft 14 can drive the squeezing roller 8 to move away from the rotating shaft 14 along the axial direction of the fixed sleeve 15, so that the distance between the squeezing roller 8 and the inner wall of the reactor 1 is reduced, and the squeezing roller 8 close to the inner wall of the reactor 1 will squeeze the watermelon seeds attached to the inner wall of the reactor 1. Then the rotating shaft 14 can drive the squeezing roller 8 to make a circular motion with the rotating shaft 14 as the axis and the distance between the squeezing roller 8 and the rotating shaft 14 as the radius. The friction generated between the squeezing roller 8 doing the circular motion and the watermelon seeds can be used to remove the sticky substances adhering to the surface of the watermelon seeds.

[0031] By setting a bidirectional driving structure, when the rotating shaft 14 rotates, the squeezing roller 8 is affected by the centrifugal force to move away from the rotating shaft 14 and rotate along with the rotating shaft 14. The rotating squeezing roller 8 cooperates with the inner wall of the reactor 1, and can generate squeezing friction on the watermelon seeds placed between the squeezing roller 8 and the inner wall of the reactor 1, thereby removing the sticky substances adhering to the surface of the watermelon seeds.

[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , a cleaning device with controllable extrusion force, further comprising an adjustment component, which is arranged on the rotating shaft 14 and connected to the extrusion roller 8, including an adjustment cylinder 30 rotatably mounted on the rotating shaft 14, and the adjustment cylinder 30 is slidably provided with a lifting member, and the lifting member cooperates with the embedded groove body provided on the adjustment cylinder 30, and can adjust the bidirectional extrusion structure to change the distance between the extrusion roller 8 and the rotating shaft 14 when the rotating shaft 14 rotates; For details, please refer to Figure 2 , Figure 7 , Figure 8 , Fig. 9 , Fig.10A knob 31 is coaxially fixedly provided at one end of the adjusting cylinder 30 facing the rotating sleeve 20, and the knob 31 is rotatably connected to the rotating shaft 14. The setting of the knob 31 is conducive to controlling the rotation of the adjusting cylinder 30 relative to the rotating shaft 14. When the adjusting cylinder 30 rotates relative to the rotating shaft 14, the lifting member cooperates with the interlocking groove body provided on the adjusting cylinder 30, and can drive the lifting member to rise and fall along the axial direction of the adjusting cylinder 30, thereby changing the distance between the above-mentioned moving member and the rotating shaft 14, thereby changing the elastic potential energy stored in the first spring 19 in the initial state.

[0033] The moving member includes a guide plate 18 slidably connected to the slide bar 17, a guide groove 1801 is provided on the guide plate 18, and a sleeve plate 1802 is fixedly provided on the guide plate 18, and the sleeve plate 1802 is slidably provided on the slide bar 17; For details, please refer to Figure 3 , Figure 4 , Figure 7 , the above-mentioned sleeve plate 1802 is slidably arranged in the through groove 16 provided on the fixed sleeve 15. In the initial state, the sleeve plate 1802 is away from the rotating shaft 14, and the slide bar 17 is pushed by the elastic potential energy of the first spring 19 to fit with the bottom wall of the fixed sleeve 15. At this time, the distance between the squeezing roller 8 and the rotating shaft 14 is the smallest, and the centrifugal force generated by the rotation of the rotating shaft 14 drives the slide bar 17 to gradually move away from the rotating shaft 14. In the process of the slide bar 17 moving away from the rotating shaft 14, the elastic potential energy stored in the first spring 19 will gradually increase until the centrifugal force generated by the rotating shaft 14 is the same as the elastic potential energy stored in the first spring 19. At this time, the distance between the slide bar 17 and the rotating shaft 14 is the largest, and under the drive of the constant speed motor, the distance between the slide bar 17 and the rotating shaft 14 is always consistent. At the same time, the squeezing roller 8 can just produce contact squeezing on the watermelon seeds attached to the inner wall of the reactor 1, and then the circular motion in the reactor 1 accompanied by the squeezing roller 8 can remove the sticky substances adhering to the surface of the watermelon seeds. The lifting member includes a lifting sleeve 26 slidably disposed on the adjusting cylinder 30, a protrusion 27 is formed on the inner wall of the lifting sleeve 26, the protrusion 27 is slidably disposed in the fitting groove, and the lifting sleeve 26 is provided with two sets of pulleys 28 equidistantly along its circumferential direction, and the pulleys 28 are slidably disposed in the guide groove 1801; For details, please refer to Figure 3 , Figure 7 , Figure 8 The guide groove 1801 is an inclined groove. In the initial state, the guide plate 18 is away from the rotating shaft 14, and the lifting sleeve 26 is close to the knob 31. At this time, the pulley 28 is located at the head end of the guide groove 1801, and the elastic potential energy stored in the first spring 19 is the smallest. This is suitable for the working state with the lowest motor speed.

[0034] The engaging groove body includes a horizontal groove 3002 and a spiral groove 3003 which are continuously formed on the outer wall of the adjusting cylinder 30, and a locking groove 3001 is formed on the horizontal groove 3002; For details, please refer to Figure 2 , Figure 8 , Fig. 9 A second spring 29 is also slidably provided on the adjusting cylinder 30, one end of the second spring 29 abuts against the knob 31, and the other end abuts against the lifting sleeve 26. In the initial state, the second spring 29 is in a compressed state. The second spring 29 in the compressed state pushes the protruding column 27 to engage with the locking groove 3001. At this time, the lifting sleeve 26 and the adjusting cylinder 30 remain relatively fixed, thereby fixing the guide plate 18 relative to the fixed sleeve 15. When it is necessary to adjust the motor to work at a higher speed, the knob 31 should be turned toward the transmission roller 11 first. At this time, the protruding column 27 is separated from the locking groove 3001 and slides into the horizontal groove 3002. With the continuous rotation of the knob 31, the protruding column 27 slides along the horizontal groove 3002 into the spiral groove 3003, and slides along the spiral groove 3003 to In the next horizontal groove 3002, until the protruding column 27 comes to the locking groove 3001 opened on the next horizontal groove 3002, the compressed second spring 29 releases its elastic potential energy, pushing the lifting sleeve 26 away from the knob 31, so that the protruding column 27 is engaged with the locking groove 3001. At this time, the lifting sleeve 26 descends a certain distance. During the descent, the pulley 28 and the groove wall of the guide groove 1801 are in contact and extrusion, pushing the guide plate 18 along the axial direction of the slide bar 17 toward the rotating shaft 14, so that the first spring 19 is further compressed, so that its stored elastic potential energy is increased, and then the motor is started. When the motor with increased speed drives the rotating shaft 14 to rotate, the distance between the squeezing roller 8 driven away from the rotating shaft 14 by centrifugal force and the rotating shaft 14 can still reach the maximum distance and remain unchanged during the rotation process.

[0035] In the actual operation process, the speed of the rotating shaft 14 is adjusted according to the production requirements. When the rotating speed of the rotating shaft 14 is faster, the squeezing roller 8 rotates faster in the reactor 1, and the time for cleaning the watermelon seeds is shorter. However, the centrifugal force generated when the rotating shaft 14 rotates after the speed is increased will be greater. At this time, in the initial state, the elastic potential energy stored in the first spring 19 cannot balance the centrifugal force generated by the rotating shaft 14, and the distance between the squeezing roller 8 and the inner wall of the reactor 1 will be reduced. At this time, driven by the high-speed rotating shaft 14, the squeezing force of the squeezing roller 8 on the watermelon seeds becomes larger, which will crush the watermelon seeds. Therefore, it is necessary to set an adjustment component to change the elastic potential energy stored in the first spring 19 in the initial state, so that when the rotating shaft 14 works at different speeds, the distance between the squeezing roller 8 driven away from the rotating shaft 14 by the centrifugal force and the inner wall of the reactor 1 is constant and equal, and the friction and squeezing between the squeezing roller 8 and the watermelon seeds will not be reduced due to the speed adjustment, thereby affecting the cleaning quality. See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , a cleaning device with controllable extrusion force, further comprising a kneading assembly, which is arranged in the reactor 1 and connected to the extrusion roller 8 and the rotating shaft 14, and when the rotating shaft 14 rotates, the kneading assembly can drive the extrusion roller 8 to rotate; For details, please refer to Figure 2 , Figure 4 , Figure 5 , Figure 7 A series of silicone convex points are arranged at equal intervals on the silicone pad, so that the surface of the squeezing roller 8 presents an uneven structure. When the squeezing roller 8 is rotated under the control of the kneading component, the convex points arranged on the silicone pad help the squeezing roller 8 to clean the watermelon seeds, thereby improving the cleaning quality of the seeds.

[0036] The kneading assembly includes a linkage structure and a driving structure. The linkage structure is provided with two groups, which are respectively connected to the squeezing rollers 8 provided in the reactor 1, and include a rotating sleeve 20 rotatably connected to the rotating shaft 14, and a first connecting plate 25 is rotatably installed on the rotating sleeve 20. A transmission rod 21 is rotatably installed at one end of the first connecting plate 25 away from the rotating sleeve 20. The transmission rod 21 is respectively connected to the rotating sleeve 20 and the squeezing roller 8 through a first transmission belt 24 and a second transmission belt 22, and a second connecting plate 23 is also provided between the transmission rod 21 and the squeezing roller 8; The driving structure includes a transmission roller 11 rotatably mounted on the reactor 1, the transmission roller 11 is connected to the rotating shaft 14 via a belt 12, and the transmission roller 11 is connected to the rotating sleeve 20 via a linkage gear 13; The linkage gear 13 includes a driving wheel and a driven wheel, wherein the driving wheel is coaxially fixedly connected to the transmission roller 11, and the driven wheel is coaxially fixedly connected to the rotating sleeve 20; For details, please refer to Figure 2 , Figure 6 When the watermelon seeds are cleaned, the transmission roller 11 installed in the reactor 1 will rotate continuously in the same direction with the rotating shaft 14 under the connection of the belt 12. At this time, the driving wheel and the driven wheel coaxially fixed with the transmission roller 11 enter a meshing transmission state, which can drive the rotating sleeve 20 and the rotating shaft 14 to rotate in the opposite direction. For further information, see Figure 2 , Figure 4 , Figure 5 When the rotating sleeve 20 rotates, it can drive the first transmission belt 24 to rotate continuously in the same direction. The rotating first transmission belt 24 drives the transmission rod 21 to rotate in the same direction with the first transmission belt 24, and then drives the second transmission belt 22 to drive, so that the squeezing roller 8 and the rotating shaft 14 keep rotating in opposite directions, and then rub the watermelon seeds placed between the inner wall of the reactor 1 and the squeezing roller 8 to remove the sticky substances adhering to the surface of the watermelon seeds, which is beneficial to improve the germination rate of the watermelon seeds.

[0037] In particular, the first transmission belt 24 and the second transmission belt 22 are toothed belts, which can prevent the first transmission belt 24 or the second transmission belt 22 from slipping during operation, thereby affecting the cleaning quality of the squeezing roller 8 for the watermelon seeds.

[0038] By setting up a kneading component and utilizing the cooperation between the driving structure and the linkage structure, the squeezing roller 8 can rotate along with the rotating shaft 14, thereby kneading the watermelon seeds placed between the inner wall of the reactor 1 and the squeezing roller 8. Moreover, due to the uneven structure of the surface of the squeezing roller 8, the sticky substances adhering to the surface of the watermelon seeds can be more effectively removed, the outer skin of the seeds can be rubbed off, and the seed cleaning efficiency is improved, which is beneficial to improving the germination rate of the watermelon seeds.

[0039] See also Figure 1 , a cleaning device with controllable extrusion force, further comprising a water adding structure, which is arranged on the reactor 1 and connected to the rotating shaft 14, and when the rotating shaft 14 rotates, the water adding structure can inject water inward along the tangential direction of the inner wall of the reactor 1; The water adding structure includes a placing plate 2 fixedly mounted on the outer wall of the reactor 1, an impeller pump 3 fixedly mounted on the placing plate 2, the axle of the impeller pump 3 is coaxially fixed with a connecting rod 4 rotatably mounted in the reactor 1, and the end of the connecting rod 4 away from the impeller pump 3 is connected to the transmission roller 11 through a bevel gear set 10.

[0040] The bevel gear set 10 comprises a first bevel gear and a second bevel gear, wherein the first bevel gear is coaxially fixedly connected to the transmission roller 11, and the second bevel gear is coaxially fixedly connected to the connecting rod 4; See also Figure 1 , Figure 2 As can be seen from the above, after starting the motor, the transmission roller 11 rotates with the rotating shaft 14 under the connection of the belt 12, and the first bevel gear and the second bevel gear enter into a meshing transmission state, which can drive the impeller pump 3 to work, and pump water to the water inlet pipe 7 through the connecting water pipe 5, and then the water is injected inward along the tangential direction of the inner wall of the reactor 1 by the water inlet pipe 7. The water injected into the reactor 1 flows spirally along the inner wall of the reactor 1 and finally flows out from the water outlet pipe 6. It should be noted that the spirally flowing water flow injected into the reactor 1 by the water inlet pipe 7 is opposite to the rotation direction of the rotating shaft 14, and the eddy current centripetal force generated by the water flow is greater than the vortex centripetal force of the rotating shaft 14, so that during the cleaning process, the water flow can always drive the watermelon seeds to rotate in the opposite direction to the rotating shaft 14, so that the squeezing roller 8 can remove the sticky substances on the surface of the watermelon seeds, and the sticky substances removed from the watermelon seeds will be discharged from the water outlet pipe 6 following the flowing water source.

[0041] As an embodiment of the present invention, the application of the cleaning equipment with controllable extrusion force in the production of crop seeds can clean watermelon seeds, remove sticky substances adhering to the surface of watermelon seeds, and rub off the outer skin of the seeds, which is beneficial to improving the germination rate of seeds.
