Description

Technical Field

[0001] This utility model relates to the field of rice production technology, specifically to an airlock for rice production and processing. Background Technology

[0002] A rotary valve, also known as a feeder, airlock valve, or rotary valve, is a device that ensures that the air pressure in the conveying pipe does not leak, enabling the safe conveying and collection of materials. Rotary valves are often needed during rice processing.

[0003] A search revealed a Chinese patent document disclosing a positive pressure airlock for rice processing [Announcement No.: CN217807451U]. This positive pressure airlock for rice processing includes an airlock body, a receiving tube fixedly connected to the top of the output end of the airlock body, a sieve plate hinged to the top of the inside of the receiving tube, and a drive mechanism installed at the bottom of the inside of the receiving tube; a movement gap is left between the two ends of the outside of the sieve plate and the two ends of the inner wall of the receiving tube; the drive mechanism includes a rotary motor.

[0004] The airlock disclosed in this patent can screen rice before it enters the airlock body, making it easier to intercept rice bran. However, it still has shortcomings in actual use. Although it can screen rice through the screening plate, rice bran accumulates on the surface of the screening plate. Over time, this not only affects the subsequent screening effect, but also makes it inconvenient to clean the rice bran. Utility Model Content

[0005] The purpose of this utility model is to provide an airlock for rice production and processing to solve the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rice production and processing airlock, comprising an airlock body and a feeding hopper connected to its top, and further comprising:

[0007] The screening plate is installed inside the feed hopper, and connecting plates are fixed at the front and rear of the bottom of the screening plate. A swing structure for driving it to swing back and forth is provided on the right side of the bottom of the screening plate.

[0008] A first motor is fixed to the right side of the feed hopper. The output shaft of the first motor is bolted with a reciprocating screw, and the other end of the reciprocating screw is rotatably connected to the inner side of the feed hopper. A screw sleeve is threaded onto the surface of the reciprocating screw, and a cleaning plate is fixed to the bottom of the screw sleeve.

[0009] A discharge port is provided on the left side of the inner side of the feed hopper. A sealing plate is hinged to one side of the discharge port. A sliding groove is provided on the left side of the sealing plate. A slider is slidably connected inside the sliding groove.

[0010] A discharge hopper is connected to the left side of the feed hopper. A collection box is connected to the bottom of the discharge hopper. A movable block is movably connected to the top of the discharge hopper. A connecting rod is hinged between the bottom end of the movable block and the slider.

[0011] Preferably, the oscillating structure includes a second motor fixed to the surface of the feed hopper, a rotating rod fixed to the output shaft of the second motor, cams fixed to both sides of the rotating rod, a movable rod fixed to the front and rear of the inner wall of the feed hopper, and a spring sleeved on the surface of the movable rod. The two ends of the spring are fixed to the vertical plate at the bottom of the screening plate and the inner wall of the feed hopper.

[0012] Preferably, a sliding rod is fixed at the front of the inside of the feed hopper, and a sliding sleeve is movably connected to the surface of the sliding rod, with the bottom of the sliding sleeve fixed to the top of the cleaning plate.

[0013] Preferably, a guide plate is fixed on the right side of the inner cavity of the feed hopper, and the guide plate is located above the right end of the screening plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] When the screening plate is used multiple times, the reciprocating screw and the screw sleeve are connected by threads, which can move the cleaning plate to the left at the top of the screening plate. This allows the cleaning plate to clean the rice bran on the top of the screening plate. Before cleaning, the connecting rod is forcefully applied to the movable block and the top of the discharge hopper, causing the sealing plate to deflect at an angle, thus exposing the discharge port. This allows the rice bran to be swept to the discharge port for collection in the collection box. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 As shown, a rice production and processing airlock includes an airlock body 1 and a feeding hopper 2 connected to its top. A screening plate 3 is installed inside the feeding hopper 2, and connecting plates 8 are fixed to the front and rear sides of the bottom of the screening plate 3. A swinging structure 9 for reciprocating oscillation is installed on the right side of the bottom of the screening plate 3. A first motor 11 is fixedly connected to the right side of the feeding hopper 2. A reciprocating screw 12 is bolted to the output shaft of the first motor 11, and the other end of the reciprocating screw 12 is rotatably connected to the inner side of the feeding hopper 2. The surface of the reciprocating screw 12 is threaded. There is a screw sleeve 13, and a cleaning plate 14 is fixed to the bottom of the screw sleeve 13. A discharge port 4 is opened on the left side of the inner side of the feed hopper 2, and a sealing gasket is provided on the inner side of the discharge port 4. A sealing plate 5 is hinged to one side of the discharge port 4. A sliding groove 6 is opened on the left side of the sealing plate 5. A slider 7 is slidably connected inside the sliding groove 6. A discharge hopper 17 is connected to the left side of the feed hopper 2 and to the discharge port 4. A collection box 18 is connected to the bottom of the discharge hopper 17. A movable block 19 is movably connected to the top of the discharge hopper 17. A connecting rod 20 is hinged between the bottom end of the movable block 19 and the slider 7.

[0027] The oscillating structure 9 includes a second motor 91, a rotating rod 92, a cam 93, a movable rod 94, and a spring 95. The second motor 91 is fixed to the surface of the feed hopper 2, and its output shaft is fixed to one end of the rotating rod 92. The other end of the rotating rod 92 is rotatably connected to the inside of the feed hopper 2. There are two cams 93, both fixed to the two sides of the surface of the rotating rod 92. The movable rod 94 is fixed to the front and rear sides of the right side of the inner wall of the feed hopper 2. The bottom of the screening plate 3 is movably connected to the surface of the movable rod 94. The spring 95 is sleeved on the surface of the movable rod 94. Both ends are fixed to the vertical plate at the bottom of the screening plate 3 and the inner wall of the feed hopper 2. When the screening plate 3 is oscillating, the second motor 91 can be started and the rotating rod 92 can be rotated. At the same time, the two cams 93 are rotated, so that the protruding part of the cam 93 rotates to the right side, thereby applying force to the connecting plate 8, so that the screening plate 3 can squeeze the spring 95. After the cam 93 rotates to the starting position, the spring 95 will use its own elastic force to drive the screening plate 3 back to the left side, thus facilitating the reciprocating oscillation of the screening plate 3.

[0028] A sliding rod 15 is fixed at the front of the inside of the feed hopper 2. A sliding sleeve 16 is movably connected to the surface of the sliding rod 15. The bottom of the sliding sleeve 16 is fixed to the top of the cleaning plate 14, which can help limit the cleaning plate 14 and facilitate its left and right movement.

[0029] A guide plate 10 is fixed on the right side of the inner cavity of the feed hopper 2. The guide plate 10 is located above the right end of the screening plate 3, so as to guide the falling rice and facilitate its falling into the top of the screening plate 3 for screening.

[0030] A push plate 21 is fixed to the top of the movable block 19. A limit pin 22 is provided through the interior of the other end of the push plate 21. Limit holes 23 are opened on both sides of the top of the discharge hopper 17. The other end of the limit pin 22 is used in conjunction with the interior of the limit hole 23, so as to conveniently fix the position of the movable block 19 after it is moved.

[0031] The collection box 18 is movably connected to the collection box 24, and the surface of the collection box 24 is provided with a handle, which not only makes it convenient to collect what falls into the collection box 18, but also makes it convenient to pull it out for cleaning.

[0032] It is worth noting that the technical features proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.

[0033] Working principle: Before use, ensure that the sealing plate 5 has not deflected and seal the inside of the discharge port 4. Then, connect the feed hopper 2 to the external equipment and discharge rice into the airlock body 1 through the feed hopper 2. After the rice falls onto the top of the screening plate 3, driven by the swing structure 9, the screening plate 3 can swing back and forth, thereby screening the rice and rice bran. After the screening plate 3 has been used multiple times, the limit pin 22 can be pulled out, and the limit on the push plate 21 can be removed. The movable block 19 can then slide to the left on the top of the discharge hopper 17. During the sliding, force is applied to the connecting rod 20, thereby causing the sealing plate 5 to deflect at an angle, exposing the discharge port 4. Then, the first motor 11 can be started, driving the reciprocating screw 12 to rotate, while simultaneously driving the screw sleeve 13 and cleaning plate 14 to move to the left. This allows the cleaning plate 14 to sweep the impurities on the top of the screening plate 3 into the interior of the discharge hopper 17, where they fall into the collection box 18 for collection and processing.
