Detailed implementation manner

[0031] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0032] Example 1: As Figures 1 to 6 shown, an energy-saving rice processing, cleaning and drying device described in an embodiment of the present invention includes:

[0033] A processing box, the processing box includes a bottom box 1, a top cover 2 is hinged to the top of the bottom box 1, a water inlet pipe 3 and a drain pipe 4 are fixed to the lower part of the bottom box 1, and both the water inlet pipe 3 and the drain pipe 4 are controlled by valves;

[0034] A cleaning barrel 6, the cleaning barrel 6 is rotatably installed on the upper part of the processing box, a plurality of through holes 7 are evenly distributed on the side wall of the cleaning barrel 6, the number of through holes 7 opened is much more than that shown in the illustration of the present invention, the through holes 7 allow water to pass through, but do not allow complete rice grains to pass through, one end of the cleaning barrel 6 is fixed with a discharge pipe 9, the other end of the cleaning barrel 6 is fixed with an air inlet pipe 20, a feed inlet is opened above the air inlet pipe 20, a cover plate 8 is hinged in the feed inlet, and the cover plate 8 is locked with the cleaning barrel 6 through a movable buckle;

[0035] A connecting component, through which the cleaning barrel 6 is installed on the processing box;

[0036] A driving component, through which the driving component drives the cleaning barrel 6 to rotate;

[0037] During operation, first open the top cover 2 and the cover plate 8, add the rice to be cleaned into the interior of the cleaning barrel 6 from the feed inlet, lock the cover plate 8 through the buckle, then close the top cover 2, and then inject clean water into the interior of the bottom box 1 through the water inlet pipe 3. The clean water passes through the through holes 7 and enters the barrel, so that the rice inside the cleaning barrel 6 is immersed below the water surface, making the rice fully contact with the water. Then start the driving component, and through the driving component, drive the cleaning barrel 6 to rotate, driving the rice inside to move in the water, so as to wash the rice. By continuously rotating the cleaning barrel 6, the rice can be continuously washed, effectively removing the dust and debris on the surface of the rice;

[0038] After the cleaning is completed, the rice washing water inside the bottom box 1 is discharged through the drain pipe 4. The rice washing water can be collected and utilized to save water resources. Then, hot air generated by an external hot air blower is introduced into the cleaning barrel 6 through the air inlet pipe 20. The hot air is used to heat the rice and evaporate the moisture in the rice, thereby drying the rice. The bottom box 1 and the top cover 2 cooperate to enclose the cleaning barrel 6 inside, so as to reduce heat loss and improve the drying effect, in order to save heat. In addition, during the drying process, the cleaning barrel 6 continues to rotate to drive the rice to move continuously, so that the rice comes into more contact with the hot air and improves the drying efficiency.

[0039] The connection assembly includes a bearing one 10 and a bearing two 12. The bearing one 10 and the bearing two 12 are respectively arranged on both sides of the cleaning barrel 6. The bearing one 10 is fixed on the discharge pipe 9. A connecting pipe 13 is fixed in the middle of the bearing two 12. One end of the connecting pipe 13 away from the cleaning barrel 6 is connected to an external hot air pipe through a rotating connector. One end of the connecting pipe 13 close to the cleaning barrel 6 is slidably sleeved with a movable sleeve 18. A spring one 19 for resetting it is installed inside the movable sleeve 18. A limiting slider is fixed on the inner wall of the movable sleeve 18, and a sliding groove is arranged on the outer wall of the connecting block. Through the cooperation of the limiting slider and the sliding groove, the movable sleeve 18 can only move linearly along the connecting pipe 13. A square air inlet pipe 20 is fixed on one side of the cleaning barrel 6 away from the discharge pipe 9. A jack matching with the air inlet pipe 20 is opened in the middle of the movable sleeve 18.

[0040] The bearing one 10 is fixedly connected to the treatment box through a rotating bracket 11. The bearing two 12 is fixed on the bottom box 1. Both the bearing one 10 and the bearing two 12 are engaged in the mounting holes opened at both ends of the bottom box 1 and the top cover 2.

[0041] During operation, by pushing the movable sleeve 18 in a direction away from the cleaning barrel 6, the spring one 19 is compressed. Then, the cleaning barrel 6 is rotated to the horizontal position, and then the movable sleeve 18 is released. The spring one 19 pushes the movable sleeve 18 to reset, so that the air inlet pipe 20 in the middle of the side wall of the cleaning barrel 6 is inserted into the middle jack of the movable sleeve 18, connecting the air inlet pipe 20 with the connecting pipe 13, and the cleaning barrel 6 can be installed on the top of the bottom box 1. During the cleaning and drying processes, the bearing one 10 and the bearing two 12 are used to reduce the friction force when the cleaning barrel 6 rotates. During drying, the hot air generated by the hot air blower is transmitted to the inside of the connecting pipe 13 through the hot air pipe and then introduced into the cleaning barrel 6 through the air inlet pipe 20 to dry the rice.

[0042] After the drying work is completed, the top cover 2 is opened, and then the movable sleeve 18 is pushed again to make the air inlet pipe 20 separate from the inside of the movable sleeve 18. At this time, the cleaning barrel 6 can be rotated around the rotating bracket 11 to pour out the dried rice inside the cleaning barrel 6 from the discharge pipe 9. Then, the cleaning barrel 6 is reinstalled on the bottom box 1, and the operation is repeated for the next cleaning work.

[0043] A hydraulic cylinder 16 is fixedly installed at the bottom of the bottom case 1. There are a pair of the hydraulic cylinders 16, which are symmetrically distributed on both sides below the cleaning barrel 6. The top end of the telescopic rod of the hydraulic cylinder 16 is fixedly installed with a rubber pad. During operation, by controlling the telescopic rod of the hydraulic cylinder 16 to extend upward, the cleaning barrel 6 can be pushed upward, so as to automatically turn over the cleaning barrel 6, saving labor and improving the discharging efficiency.

[0044] The driving assembly includes a motor 5. The output shaft of the motor 5 and the connecting pipe 13 are connected by a transmission belt and a transmission wheel. During operation, the motor 5 is started, and the kinetic energy of the motor 5 is transmitted to the connecting pipe 13 through the transmission belt and the transmission wheel. The air inlet pipe 20 is designed as a square pipe and is adapted to the jack in the movable sleeve 18, so that the cleaning barrel 6 is driven to rotate synchronously through the connecting pipe 13.

[0045] A cross pipe 17 is fixedly installed in the middle of the bottom case 1. A slender through groove 23 is formed at the top of the cross pipe 17. A fan is arranged inside the tail end of the housing of the motor 5. A guide air pipe 14 is fixedly installed at the front end of the housing of the motor 5. One end of the guide air pipe 14 away from the motor 5 is connected to the air inlet end of the cross pipe 17 through a filter box 15.

[0046] During operation, when the motor 5 works, the internal fan is synchronously driven to rotate (the connection and driving principle of the fan are publicly known technologies and will not be elaborated here). By rotating the fan, the air flow inside the housing of the motor 5 is accelerated, and the heat generated during the operation of the motor 5 can be discharged to keep the normal working temperature of the motor 5. In addition, during the cleaning process, the air inside the housing of the motor 5 is introduced into the cross pipe 17 through the guide air pipe 14. The cross pipe 17 is attached to the bottom of the cleaning barrel 6, and the air is discharged from the through groove 23 to form air bubbles. The air bubbles enter the inside of the cleaning barrel 6 from the through holes 7, which can drive the rice to turn in the water, thereby improving the cleaning efficiency of the rice. During the drying process, the hot air inside the motor 5 is continuously discharged from the through groove 23 of the cross pipe 17, and the heat generated during the operation of the motor 5 can be transferred to the rice to accelerate the drying of the rice. In addition, the hot air blows the rice upward, which can make the rice turn over and increase the contact area between the rice and the hot air, further improving the drying efficiency of the rice. In the above process, by effectively using the wind force and heat generated during the operation of the motor, not only the working efficiency is improved, but also energy can be saved and energy waste can be reduced.

[0047] A movable frame is slidably installed on the side of the filter box 15, and a layer of activated carbon 21 and a layer of filter screen 22 are installed inside the movable frame; during operation, by arranging the layer of activated carbon 21, the peculiar smell generated due to friction, lubricating oil or other chemical reactions during the operation of the motor 5 can be adsorbed, helping to purify the discharged air; by arranging the layer of filter screen 22, the dust in the air can be filtered; in addition, the movable frame can be drawn out of the filter box 15 to facilitate the replacement of the layer of activated carbon 21 and the layer of filter screen 22.

[0048] When the cleaning bucket 6 is horizontally placed inside the processing box, the horizontal pipe 17 contacts the bottom of the cleaning bucket 6; during operation, when it is necessary to connect the cleaning bucket 6 to the connecting pipe 13, first move the movable sleeve 18, then support the cleaning bucket 6 through the horizontal pipe 17, and then the cleaning bucket 6 can be rotated, so that the air inlet pipe 20 on the side of the cleaning bucket 6 can be aligned with the middle socket of the movable sleeve 18, facilitating the insertion of the air inlet pipe 20 into the movable sleeve 18.

[0049] Embodiment 2: As Figure 6 shown, compared with Embodiment 1, another implementation manner of the present invention is: two cylinders 24 are symmetrically fixed on the inner wall of the cleaning bucket 6, the bottom of the cylinder 24 communicates with the through hole 7 on the barrel wall, a movable block 25 is slidably installed in the middle of the cylinder 24, and a second spring 26 for resetting the movable block 25 is installed inside the cylinder 24; during operation, during the drying process, the through slots 23 on the side wall of the horizontal pipe 17 continuously eject air outwards. During the rotation of the cleaning bucket 6, the cylinder 24 rotates synchronously with the cleaning bucket 6. When the cylinder 24 rotates to face the through slot 23, the air ejected from the through slot 23 enters the inside from the open bottom of the cylinder 24, thereby pushing the movable block 25 upwards, and the second spring 26 is compressed. When the cylinder 24 and the through slot 23 are misaligned, the second spring 26 rebounds to push the movable block 25 to reset, so that the movable block 25 knocks on the inner wall of the cleaning bucket 6, and the generated vibration can separate the rice from the barrel wall, preventing the rice from adhering to the inner wall of the cleaning bucket 6, so that the rice can be in full contact with the hot air, improving the drying rate.

[0050] Working principle: Open the top cover 2 and the cover plate 8, add the rice to be cleaned into the cleaning bucket 6 from the feed port, lock the cover plate 8 through the buckle, then close the top cover 2, and then inject clean water into the bottom box 1 through the water inlet pipe 3. The clean water passes through the through hole 7 and enters the bucket, so that the rice inside the cleaning bucket 6 is soaked below the water surface. Then start the driving component, and drive the cleaning bucket 6 to rotate through the driving component, driving the rice inside to move in the water, so as to wash the rice. By continuously rotating the cleaning bucket 6, the rice can be continuously washed, effectively removing the dust and debris on the surface of the rice;

[0051] After the cleaning is completed, the rice washing water inside the bottom box 1 is drained through the drain pipe 4. The rice washing water can be collected and utilized to save water resources. Then, hot air generated by an external hot air blower is introduced into the cleaning barrel 6 through the air inlet pipe 20, and the hot air is used to heat the rice to evaporate the water in the rice, thereby drying the rice. The bottom box 1 and the top cover 2 cooperate to enclose the cleaning barrel 6 inside to reduce heat loss and improve the drying effect, so as to save heat. In addition, during the drying process, the cleaning barrel 6 continues to rotate to drive the rice to continue moving, so that the rice comes into more contact with the hot air and improves the drying efficiency.

[0052] When the driving component works, the motor 5 synchronously drives the internal fan to rotate, and the rotation of the fan accelerates the air circulation inside the housing of the motor 5, which can discharge the heat generated during the operation of the motor 5 and maintain the normal operating temperature of the motor 5. In addition, the air inside the housing of the motor 5 is introduced into the horizontal pipe 17 through the air guide pipe 14. The horizontal pipe 17 is attached to the bottom of the cleaning barrel 6, and the air is discharged from the through groove 23 to form bubbles. The bubbles enter the cleaning barrel 6 through the through hole 7, which can drive the rice to tumble in the water, thereby improving the cleaning efficiency of the rice. During the drying process, the hot air inside the motor 5 continuously discharges from the through groove 23 of the horizontal pipe 17, and the heat generated during the operation of the motor 5 can be transferred to the rice to accelerate the drying of the rice. In addition, the hot air blows the rice upward, which can make the rice tumble and increase the contact area between the rice and the hot air, further improving the drying efficiency of the rice.

[0053] During the drying process, the through groove 23 on the side wall of the horizontal pipe 17 continuously sprays air outward. During the rotation of the cleaning barrel 6, the cylinder body 24 rotates synchronously with the cleaning barrel 6. When the cylinder body 24 rotates to be opposite to the through groove 23, the air sprayed from the through groove 23 enters the inside from the open bottom of the cylinder body 24, and then pushes the movable block 25 to move upward, and the second spring 26 is compressed. When the cylinder body 24 and the through groove 23 are misaligned, the second spring 26 rebounds to push the movable block 25 to reset, so that the movable block 25 knocks on the inner wall of the cleaning barrel 6, and the generated vibration can separate the rice from the barrel wall, preventing the rice from adhering to the inner wall of the cleaning barrel 6, so that the rice can come into full contact with the hot air and improve the drying rate.

Taking the observer's perspective as the standard, the side of the device facing the observer is defined as the front, and the left side of the observer is defined as the left, and so on.
