Technical Field

[0001] This utility model relates to the field of drying technology, specifically a drying machine for rice processing. Background Technology

[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials, used for drying objects. Dryers work by heating materials to vaporize and release the moisture (generally water or other volatile liquid components) to obtain solid materials with a specified moisture content. Dryers are also used in rice processing to evaporate the moisture.

[0003] The rice dryer disclosed in publication number "CN220339019U" includes a conveyor frame, a drying chamber and an adjustment assembly mounted on top of the conveyor frame; and a feeding assembly including a hopper. A bearing seat is fixedly connected to the outer wall of the hopper's support. A reciprocating screw is rotatably connected inside the bearing seat. A first nut assembly is connected to the outside of the reciprocating screw. A first connecting seat is fixedly connected to the outer wall of the first nut assembly, and a draining plate is fixedly connected to the other end of the first connecting seat. This invention, through the feeding assembly, allows for control and adjustment of the rice output by adjusting the size of the gap at the hopper's outlet, effectively preventing rice accumulation. Simultaneously, the reciprocating movement of the draining plate ensures smooth rice feeding. Furthermore, the adjustment assembly allows for adaptive adjustment of the width of the rice discharged at the tail end.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] When drying rice, it is usually placed on a conveyor belt in a dryer and transported to the drying chamber for drying. However, considering that rice is prone to accumulating during the drying process, it will affect the drying effect. Utility Model Content

[0006] The purpose of this invention is to provide a rice drying machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A rice drying machine includes a conveyor, a drying chamber, and a hot air blower. The drying chamber is fixedly installed on the top of the conveyor, and the hot air blower is fixedly installed on the top of the drying chamber. Two dispersing plates are arranged inside the drying chamber, and a dispersing rod is fixedly connected to the bottom of the dispersing plates. A transmission mechanism is arranged on the top of the drying chamber.

[0009] The transmission mechanism includes a motor fixedly connected to the top of the drying chamber. The output end of the motor extends into the interior of the drying chamber and is fixedly connected to a rotating rod. A transmission disc is fixedly connected to the bottom of the rotating rod. Two transmission rods that cooperate with a dispersing plate are fixedly connected to the bottom of the transmission disc. A spring is fixedly connected to one side of the dispersing plate. One end of the spring is fixedly connected to the inner wall of the drying chamber. A blower mechanism is provided on one side of the drying chamber.

[0010] Preferably, the blower mechanism includes a compression chamber fixedly connected to one side of the drying chamber, and one side of the compression chamber is fixedly connected to a jet pipe via a one-way pressure valve. One end of the jet pipe extends into the interior of the drying chamber and is fixedly connected to a jet hood.

[0011] Both sides of the compression box are fixedly connected to transmission pipes. One end of the transmission pipe is fixedly connected to a gas collecting box. One side of the gas collecting box is fixedly connected to the surface of the drying box. An air inlet pipe is fixedly connected to the top of the gas collecting box. A pushing block is movably connected inside the gas collecting box. A pushing rod is fixedly connected to one side of the pushing block. One end of the pushing rod penetrates into the interior of the drying box and is fixedly connected to one side of the dispersing plate.

[0012] Preferably, a piston is fixedly connected to one side of the push block, and the piston is made of rubber.

[0013] Preferably, a first one-way valve is fixedly installed on the surface of the intake pipe, and a second one-way valve is fixedly installed on the surface of the transmission pipe.

[0014] Preferably, the number of dispersing rods is several, and they are evenly distributed at the bottom of the dispersing plate.

[0015] Preferably, a support frame is fixedly connected to the inner wall of the drying oven, and the inner wall of the support frame is rotatably connected to the surface of the rotating rod through a bearing.

[0016] Preferably, the inner wall of the drying oven is fixedly connected to two sliding rods, and a sliding hole is provided on one side of the dispersing plate to cooperate with the sliding rods.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, by setting up a transmission mechanism, enables rice to be placed on a conveyor and then transported to the drying chamber by the conveyor. Simultaneously, a motor is started, driving a rotating rod to rotate around a bearing. This rotating rod, in turn, drives a transmission disc and a transmission rod to rotate. Figure 4As shown, when the drive rod presses the dispersing plate, it will cause the two dispersing plates to move away from each other. When the drive rod rotates to the point where it no longer contacts the dispersing plate, the elastic force generated by the spring will cause the drive rod to slowly return to its original position. This cycle repeats, and the dispersing plate drives the dispersing rod to move back and forth, dispersing the rice on the conveyor to prevent it from piling up, thereby improving the drying effect.

[0019] 2. This utility model, by setting up a blower mechanism, enables the two dispersing plates to move to opposite sides, thereby driving the push rod, push block, and piston to move and compress the gas in the gas collection box. The gas then enters the compression box through the transmission pipe. When the dispersing plates return to their original position under the force of the spring, they will drive the push rod, push block, and piston to return to their original position. At this time, the gas collection box is under negative pressure, and the gas will enter through the air inlet pipe. This cycle continues until the gas in the compression box reaches its limit. At this point, the gas will be intermittently ejected through the jet pipe and jet hood, thereby driving away water vapor and further improving the drying effect. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1 - Figure 6 This utility model provides a technical solution: Example 1

[0029] A rice drying machine includes a conveyor 1, a drying chamber 2 and a hot air blower 3. The drying chamber 2 is fixedly installed on the top of the conveyor 1, and the hot air blower 3 is fixedly installed on the top of the drying chamber 2. Two dispersing plates 4 are arranged inside the drying chamber 2, and a dispersing rod 5 is fixedly connected to the bottom of the dispersing plate 4. A transmission mechanism is arranged on the top of the drying chamber 2.

[0030] The transmission mechanism includes a motor 6 fixedly connected to the top of the drying chamber 2. The output end of the motor 6 extends into the interior of the drying chamber 2 and is fixedly connected to a rotating rod 7. A transmission disc 8 is fixedly connected to the bottom of the rotating rod 7. Two transmission rods 9 that cooperate with the dispersing plate 4 are fixedly connected to the bottom of the transmission disc 8. A spring 10 is fixedly connected to one side of the dispersing plate 4. One end of the spring 10 is fixedly connected to the inner wall of the drying chamber 2. A blower mechanism is provided on one side of the drying chamber 2.

[0031] In this embodiment, considering that rice is prone to accumulating during the drying process, which can affect the drying effect, a transmission mechanism is set up. The rice is placed on conveyor 1 and then transported to the drying chamber 2. Simultaneously, motor 6 is started, driving rotating rod 7 to rotate around bearing 25. Rotating rod 7 then drives transmission disc 8 and transmission rod 9 to rotate. Figure 4 As shown, when the transmission rod 9 presses the dispersing plate 4, it will drive the two dispersing plates 4 to move away from each other. When the transmission rod 9 rotates to the point where it no longer contacts the dispersing plate 4, the elastic force generated by the spring 10 will drive the transmission rod 9 to slowly return to its original position. This cycle repeats, and the dispersing plate 4 drives the dispersing rod 5 to move back and forth, dispersing the rice on the conveyor 1 to avoid accumulation and thus improving the drying effect.

[0032] This solves the problem of rice piling up during the drying process, which can affect the drying effect.

[0033] The number of dispersing rods 5 is several, and they are evenly distributed at the bottom of the dispersing plate 4.

[0034] In this embodiment, by setting up several dispersing rods 5, the rice can be evenly dispersed by the reciprocating movement of the dispersing rods 5, effectively avoiding the accumulation of rice and improving the drying effect.

[0035] A support frame 24 is fixedly connected to the inner wall of the drying oven 2. The inner wall of the support frame 24 is rotatably connected to the surface of the rotating rod 7 through a bearing 25.

[0036] In this embodiment, by setting up a support frame 24 and a bearing 25, the rotating rod 7 and other structures can be supported, making the rotating rod 7, transmission disc 8 and transmission rod 9 more stable during rotation.

[0037] Two sliding rods 26 are fixedly connected to the inner wall of the drying oven 2, and a sliding hole 14 is provided on one side of the dispersion plate 4 to cooperate with the sliding rods 26.

[0038] In this embodiment, by setting the sliding rod 26 and the sliding hole 14, when the transmission rod 9 presses the dispersion plate 4 to transmit power, the dispersion plate 4 and other structures can only move along the trajectory of the sliding rod 26 and the sliding hole 14, thus limiting the movement trajectory. Example 2

[0039] Based on Embodiment 1, in this embodiment, the transmission mechanism can control the dispersing plate 4 and the dispersing rod 5 to reciprocate and disperse the rice, thereby improving the drying effect. However, considering that the drying effect is improved after the rice is dispersed, the amount of water vapor will also increase. If it is not removed in time, it will also affect the drying effect. In this application, the blower mechanism includes a compression box 11 fixedly connected to one side of the drying box 2. One side of the compression box 11 is fixedly connected to a jet pipe 12 through a one-way pressure valve 13. One end of the jet pipe 12 penetrates into the interior of the drying box 2 and is fixedly connected to a jet hood 15.

[0040] Both sides of the compression box 11 are fixedly connected to the transmission pipe 16. One end of the transmission pipe 16 is fixedly connected to the gas collecting box 17. One side of the gas collecting box 17 is fixedly connected to the surface of the drying box 2. The top of the gas collecting box 17 is fixedly connected to the air inlet pipe 18. The inside of the gas collecting box 17 is movably connected to the push block 19. One side of the push block 19 is fixedly connected to the push rod 20. One end of the push rod 20 penetrates into the inside of the drying box 2 and is fixedly connected to one side of the dispersion plate 4.

[0041] In this embodiment, considering that the drying effect is improved after the rice is dispersed, the amount of water vapor will also increase. If it is not removed in time, it will also affect the drying effect. Therefore, by setting up a blower mechanism, when the two dispersing plates 4 move to the side away from each other, it will drive the push rod 20, the push block 19 and the piston 21 to move, compressing the gas in the gas collection box 17, so that the gas enters the compression box 11 through the transmission pipe 16. When the dispersing plate 4 is reset under the action of the spring 10, it will drive the push rod 20, the push block 19 and the piston 21 to reset. At this time, the gas collection box 17 is under negative pressure, and the gas will enter through the air inlet pipe 18. This cycle continues. When the gas in the compression box 11 reaches its limit, the gas will be intermittently sprayed out by the jet pipe 12 and the jet hood 15 to remove the water vapor and further improve the drying effect.

[0042] This addresses the issue that while the increased dispersion of rice improves drying efficiency, it also increases water vapor production, which, if not promptly removed, can negatively impact the drying effect.

[0043] A piston 21 is fixedly connected to one side of the push block 19. The piston 21 is made of rubber.

[0044] In this embodiment, by setting piston 21, the sealing performance inside the gas collection box 17 can be improved. When the push block 19 and piston 21 move, the gas in the gas collection box 17 can be compressed.

[0045] A first one-way valve 22 is fixedly installed on the surface of the intake pipe 18, and a second one-way valve 23 is fixedly installed on the surface of the transmission pipe 16.

[0046] In this embodiment, a first one-way valve 22 and a second one-way valve 23 are provided so that when the gas in the gas collection box 17 is compressed, the gas can only enter the transmission pipe 16 through the second one-way valve 23 and then enter the compression box 11. When the gas collection box 17 is under negative pressure, the gas can only enter the gas collection box 17 through the first one-way valve 22 and the air inlet pipe 18.

[0047] Working principle: The user places rice on conveyor 1, which then transports the rice into the drying chamber 2. Simultaneously, motor 6 is started, driving rotating rod 7 to rotate around bearing 25. Rotating rod 7 then drives transmission disc 8 and transmission rod 9 to rotate. Figure 4 As shown, when the transmission rod 9 presses the dispersing plate 4, it will drive the two dispersing plates 4 to move away from each other. When the transmission rod 9 rotates to the point where it no longer contacts the dispersing plate 4, the elastic force generated by the spring 10 will drive the transmission rod 9 to slowly return to its original position. This cycle repeats, and the dispersing plate 4 drives the dispersing rod 5 to move back and forth, dispersing the rice on the conveyor 1 to avoid accumulation and thus improving the drying effect.

[0048] When the two dispersing plates 4 move to opposite sides, they drive the push rod 20, push block 19, and piston 21 to move, compressing the gas in the gas collecting box 17. The gas then enters the compression box 11 through the transmission pipe 16. When the dispersing plates 4 return to their original position under the force of the spring 10, they drive the push rod 20, push block 19, and piston 21 to return to their original position. At this time, the gas collecting box 17 is under negative pressure, and the gas enters through the air inlet pipe 18. This cycle continues until the gas in the compression box 11 reaches its limit. Then, the gas is intermittently ejected through the jet pipe 12 and jet hood 15, which removes water vapor and further improves the drying effect.
