Technical Field
[0001] The utility model relates to the technical field of rice paddy processing, in particular to rice paddy shelling equipment. Background Art
[0002] Paddy rice refers to the grain without the husk removed. Botanically, it belongs to the common rice subspecies in the common cultivated rice subgenus of the genus Oryza in the family Poaceae. The grain of rice is called paddy rice. After the husk is removed from the paddy rice, it is called brown rice. Brown rice can be obtained by grinding away the bran layer.
[0003] In the prior art drum-type hulling equipment, husks and brown rice are mixed together and discharged from the hulling device during hulling, and then the husks are separated by a separation device. The whole process is relatively cumbersome and cannot achieve automatic separation after hulling, resulting in slow hulling efficiency. Utility Model Content
[0004] The purpose of the utility model is to solve the following shortcomings in the prior art: when hulling, the husks and brown rice are mixed together in the drum-type hulling equipment in the prior art and discharged from the hulling device, and then the husks are separated by a separation device. The whole process is relatively troublesome and automatic separation after hulling cannot be achieved, resulting in slow hulling efficiency. A rice hulling equipment is proposed.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A rice hulling device comprises a box body and a cylinder, wherein the upper wall of the box body is provided with a through hole, the outer surface of the cylinder is rotatably connected to the inner wall of the through hole, the bottom wall of the cylinder is provided with a discharge pipe, and one side wall of the box body is provided with a discharge port;
[0007] A screening component is installed in the box, and the screening component includes a support rod, a screen plate, a limit plate, an L-shaped plate, and a spring. The two L-shaped plates are respectively fixedly connected to the inner walls at both ends of the box, and the screen plate is slidably connected between the two L-shaped plates. The two springs are respectively fixedly connected between the L-shaped plates and the screen plate. The support rod is fixedly connected to the lower end of the cylinder, and the limit plate is fixedly connected to the upper surface of the screen plate.
[0008] Preferably, the screening component further includes push rods, and the two push rods pass through the L-shaped plate and are fixedly connected to the screen plate.
[0009] Preferably, the upper ends of the two L-shaped plates are fixedly connected with an elliptical cylinder, a piston is slidably connected inside the elliptical cylinder, and the piston is fixedly connected to one end of the push rod away from the screen plate.
[0010] Preferably, a gas collecting chamber is fixedly connected to one of the inner walls of the box body, an exhaust port is opened on the side wall of the gas collecting chamber, the gas collecting chamber is located on the upper side of the sieve plate, and the elliptical cylinder is connected to the gas collecting chamber through a connecting pipe.
[0011] Preferably, a servo motor is fixedly connected to the upper end of the box, and a transmission belt is sleeved between the driving end of the servo motor and the upper end of the cylinder.
[0012] Preferably, a fixing plate is fixedly connected to the servo motor, and the fixing plate is slidably connected to the inner wall of the cylinder.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. When the cylinder rotates quickly, it exerts centrifugal force on the rice inside. Since the fixed plate is inside the cylinder, the rice can hit the fixed plate under the action of the centrifugal force, thus achieving the shelling effect on the rice.
[0015] 2. When the cylinder rotates continuously, the sieve plate moves up and down, which can screen the rice on the sieve plate. Since the heavier rice particles are on the sieve plate, the lighter side of the rice husk is on the upper side of the rice particles, which can achieve the effect of stratification of rice particles and rice husk.
[0016] 3. When the sieve plate moves upward, the push rod can push the piston to move in the elliptical cylinder. When the piston moves upward in the elliptical cylinder, it can squeeze the internal gas into the gas collecting chamber through the connecting pipe, and discharge it to the upper side of the sieve plate through the exhaust hole. The lighter rice husk can be blown to the outside of the box through the discharge port, thereby achieving the effect of separating rice particles and rice husks. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0023] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.
[0024] Reference Figures 1-4 A rice hulling device comprises a box body 1 and a cylinder 2. A through hole is provided on the upper wall of the box body 1. The outer surface of the cylinder 2 is rotatably connected to the inner wall of the through hole. A discharge pipe is provided on the bottom wall of the cylinder 2. An electric switch is provided on the discharge pipe to facilitate staff to control the discharge of materials inside the cylinder 2. A discharge port is provided on one side wall of the box body 1. The discharge port is used to discharge the rice husk. A servo motor 11 is fixedly connected to the upper end of the box body 1. A transmission belt 10 is sleeved between the driving end of the servo motor 11 and the upper end of the cylinder 2. A fixed plate 12 is fixedly connected to the servo motor 11, and the fixed plate 12 is slidably connected to the inner wall of the cylinder 2.
[0025] A screening component is installed in the box body 1, which includes a support rod 4, a sieve plate 5, a limit plate 6, an L-shaped plate 3, and a spring 7. The two L-shaped plates 3 are respectively fixedly connected to the inner walls at both ends of the box body 1, and the end of the L-shaped plate 3 away from the sieve plate 5 is slidably connected to the outer wall of the cylinder 2, which can play a role in the stability of the cylinder 2 during rotation. The sieve plate 5 is slidably connected between the two L-shaped plates 3, and the two springs 7 are respectively fixedly connected between the L-shaped plates 3 and the sieve plate 5. The support rod 4 is fixedly connected to the lower end of the cylinder 2, and the limit plate 6 is fixedly connected to the upper surface of the sieve plate 5. The limit plate 6 is arranged in an arc shape, and one side of the upper surface is arranged as an inclined surface. When the cylinder 2 rotates counterclockwise, the support rod 4 slides on the inclined surface of the limit plate 6 to push the sieve plate 5 downward. The screening component also includes a push rod 14. The two push rods 14 pass through the L-shaped plate 3 and are fixedly connected to the sieve plate 5. The push rod 14 strengthens the stability of the up and down reciprocating movement of the sieve plate 5.
[0026] An elliptical cylinder 9 is fixedly connected to the upper ends of the two L-shaped plates 3, and the lower end of the elliptical cylinder 9 is opened. A piston 15 is slidably connected inside the elliptical cylinder 9, and the piston 15 is also elliptical. The piston 15 is fixedly connected to the end of the push rod 14 away from the sieve plate 5. An air collecting chamber 8 is fixedly connected to one of the inner walls of the box body 1, and an exhaust port is provided on the side wall of the air collecting chamber 8. The air collecting chamber 8 is located on the upper side of the sieve plate 5, and the elliptical cylinder 9 and the air collecting chamber 8 are connected through a connecting pipe 13.
[0027] In the utility model, rice is first poured into the cylinder 2, and the servo motor 11 is driven to rotate the cylinder 2 through the transmission belt 10. When the cylinder 2 rotates quickly, centrifugal force is exerted on the rice inside. Since the fixed plate 12 is located in the cylinder 2, the rice can collide with the fixed plate 12 under the action of the centrifugal force, thereby achieving the shelling effect on the rice.
[0028] Then the discharge pipe switch on the cylinder 2 is turned on, and the rice in the cylinder 2 slides onto the sieve plate 5. The support rod 4 can slide to the upper side of the limit plate 6 as the cylinder 2 rotates continuously, and push the sieve plate 5 down, while stretching the spring 7. When the support rod 4 continues to move with the cylinder 2 and moves away from the limit plate 6, the sieve plate 5 moves up and reset under the tension of the spring 7. Therefore, when the cylinder 2 rotates continuously, the sieve plate 5 moves back and forth, which can screen the rice on the sieve plate 5. Since the rice particles are heavier and are on the sieve plate 5 The lighter side of the rice husk is on the upper side of the rice particles, which realizes the stratification of the rice particles and the rice husk. At the same time, when the sieve plate 5 moves upward, the push rod 14 can push the piston 15 to move in the elliptical cylinder 9. When the piston 15 moves upward in the elliptical cylinder 9, it can squeeze the internal gas through the connecting pipe 13 into the gas collecting chamber 8, and be discharged to the upper side of the sieve plate 5 through the exhaust hole, and the lighter rice husk can be blown to the outside of the box body 1 through the discharge port, thereby realizing the effect of separating the rice particles and the rice husk.
[0029] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.
[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
