Description

Technical Field

[0001] This utility model relates to the technical field of rice production and processing equipment, specifically to a drying device for damp, hulled rice grains used in rice processing. Background Technology

[0002] Rice is one of my country's staple grains, and its planting, harvesting, procurement, and storage are all important indicators for stabilizing people's livelihoods.

[0003] Currently, large grain silos are the best storage equipment for rice. Workers husk the harvested rice grains, and then store the husked rice in the silos. However, during storage, some rice in the silos may become damp due to environmental factors and aging equipment. Workers typically use rice drying equipment to dry the damp rice, ensuring that it can still be stored and consumed.

[0004] A relevant Chinese utility model patent, CN209333796U, discloses a rice drying device, including a drying chamber with an inlet hopper and an outlet pipe at its upper and side ends, respectively. A screen is located in the middle of the drying chamber, dividing it into an upper and lower drying chamber. A rotating shaft passes through the screen and is connected to a drive mechanism. A spiral stirring device is mounted on the rotating shaft, and multiple bushings are movably mounted on it. Dust removal devices are mounted on the bushings, each including a support frame with multiple cylinders containing springs connected to brush balls via connecting plates. Heating devices are located on both sides of the drying chamber. In operation, workers add rice to the inlet hopper, which then enters the drying chamber for drying.

[0005] The aforementioned prior art has the following drawbacks: In actual use, the amount of damp rice in the grain warehouse is huge, and workers usually need to add rice to the feed hopper frequently, which increases the labor intensity of the workers and reduces the ease of use of the equipment. Utility Model Content

[0006] The purpose of this invention is to provide a drying device for damp, hulled rice grains used in rice processing, which reduces the number of times workers need to add rice and lowers their labor intensity, thereby solving the problems mentioned in the background art.

[0007] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A drying device for damp, hulled rice grains in rice processing includes a drying body with a drying chamber. The drying chamber has an inlet and an outlet. A feeding conveyor belt is inserted at the inlet. A feeding assembly is located at the end of the feeding conveyor belt away from the drying chamber. The feeding assembly includes a feeding rack with a feeding hopper mounted on it. The bottom of the feeding hopper is connected to a feeding pipe, which faces the feeding conveyor belt. The top of the feeding hopper is connected to a feeding pipe. The end of the feeding pipe away from the feeding hopper is first connected to a vacuum pump and then extends to the ground. The vacuum pump is fixedly connected to the feeding rack. A flat cover is fixedly connected to the feeding rack facing the dryer body. The flat cover covers the feeding conveyor belt, and the bottom end of the flat cover abuts against the conveyor belt. A through flat groove is opened at the top of the flat cover. The flat groove is perpendicular to the conveying direction of the feeding conveyor belt. A flat plate is inserted in the flat groove and extends to the feeding conveyor belt. A lifting component is set between the flat plate and the flat cover. The lifting component drives the flat plate to move in a straight line up and down towards or away from the feeding conveyor belt. The feeding pipe extends into the flat cover. The opening of the feeding pipe away from the feeding hopper is located on the side of the flat plate away from the dryer body.

[0008] As a preferred embodiment of this invention, an expansion hood is fixedly connected to the inlet of the feed pipe away from the vacuum pump. The expansion hood is shaped like a flared mouth, and the smaller end of the expansion hood is inserted into the feed pipe.

[0009] In a preferred embodiment of this invention, a hot air pipe is fixedly connected to the inner wall of the drying chamber. The hot air pipe is suspended above the feeding conveyor belt and is parallel to the conveying direction of the feeding conveyor belt. A blower pipe is connected to the hot air pipe in the direction of the feeding conveyor belt. The blower pipe is aligned with the feeding conveyor belt. Multiple blower pipes are provided and are evenly distributed along the hot air pipe. An industrial hot air blower with a connecting pipe is connected to the end of the hot air pipe. One end of the connecting pipe is connected to the industrial hot air blower, and the other end is connected to the hot air pipe. The industrial hot air blower is fixedly connected to the top of the dryer body.

[0010] As a preferred embodiment of this utility model, the feeding conveyor belt is provided with a hot air baffle. The hot air baffle is connected to the part of the feeding conveyor belt located in the drying chamber. A fixing rod is provided between the hot air baffle and the hot air pipe. One end of the fixing rod is fixedly connected to the hot air baffle, and the other end is fixedly connected to the pipe body of the hot air pipe. The hot air baffle has multiple wide-spreading holes, which are evenly distributed on the hot air baffle. The hot air baffle simultaneously seals the openings of the multiple air pipes facing the feeding conveyor belt.

[0011] As a preferred embodiment of this utility model, the conveyor belt is provided with ventilation holes, the diameter of which is 1 mm. Multiple ventilation holes are provided and evenly distributed on the feeding conveyor belt. A blower is provided at the bottom of the feeding conveyor belt, and the blower blows towards the hot air pipe. The blower is not in the same vertical direction as the hot air pipe.

[0012] As a preferred embodiment of this utility model, the feeding conveyor belt is provided with a C-shaped lead-out plate at the end of the drying chamber. The lead-out plate is fixedly connected to the inner wall of the drying chamber by an auxiliary rod. One end of the lead-out plate abuts against the bottom of the end of the feeding conveyor belt, and the other end is inclined towards the ground and passes through the discharge port. Beneficial effects

[0013] The beneficial effects of this utility model are: In operation, workers use large equipment to transport a large quantity of damp rice to the feeding pipe at once. Then, the worker inserts the feeding pipe into the rice pile and turns on the vacuum pump. The vacuum pump generates negative pressure, drawing the rice into the feeding hopper through the feeding pipe. Since the feeding hopper is positioned above the conveyor belt, the rice in the hopper is fed through the feeding pipe under gravity. Compared to existing technologies, this invention allows for continuous and large-volume feeding through the combination of the vacuum pump and the feeding pipe. This not only eliminates the need for frequent feeding operations by workers, reducing their labor intensity, but also ensures continuous feeding, improving production efficiency and achieving the effect of reducing the number of times workers need to add rice, thus reducing their labor intensity. After the rice grains are fed into the feeding conveyor belt through the feeding pipe, they may accumulate on the conveyor belt. When the accumulated rice grains pass under the spreading plate, the spreading plate will flatten the rice grains according to the height set by the lifting component. During the flattening process, the spreading cover, because it is in contact with the conveyor belt, can block the rice grains moving to both sides and prevent them from falling. After the rice grains are transported out from the spreading cover, the thickness of the rice grains on the feeding conveyor belt is consistent. This not only improves the uniformity of the rice grains being heated, but also saves workers the process of sorting the rice grains, further reducing the labor intensity of the workers.

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] See Figure 1-3 As shown, a rice drying device for processing damp, hulled rice grains includes a dryer body 1, a drying chamber 11 within the dryer body 1, an inlet 111 and an outlet 112 within the drying chamber 11, a feeding conveyor belt 2 inserted at the inlet 111, and a feeding assembly 21 at the end of the feeding conveyor belt 2 furthest from the drying chamber 11. A hot air pipe 5 is fixedly connected to the inner wall of the drying chamber 11, and an industrial hot air blower 51 with a connecting pipe is connected to the end of the hot air pipe 5. One end of the connecting pipe is connected to the industrial hot air blower 51, and the other end is connected to the hot air pipe 5. The industrial hot air blower 51 is fixedly connected to the top of the dryer body 1. Through the combined use of the feeding conveyor belt 2 and the feeding assembly 21, a continuous feeding process is achieved for the dryer body 1, eliminating the need for manual feeding by workers, thus reducing the number of times workers need to add rice and lowering their labor intensity.

[0019] See Figure 1-3As shown, the feeding assembly 21 includes a feeding rack 221 mounted on the ground. A conical feeding hopper 225 is mounted on the feeding rack 221, located at the top of the feeding conveyor belt 2. A feeding pipe 223 is connected to the bottom of the feeding hopper 225, facing the feeding conveyor belt 2. A feeding pipe 224 is connected to the top of the feeding hopper 225. One end of the feeding pipe 224, away from the feeding hopper 225, is first connected to a vacuum pump 222, and then extends to the ground. The vacuum pump 222 is fixedly connected to the feeding rack 221. An expansion cover 2231 is fixedly connected to the opening of the feeding pipe 224 at the ground. The expansion cover 2231 is funnel-shaped, with its smaller end inserted into the feeding pipe 224. The expansion cover 2231 increases the contact area between the feeding pipe 224 and the rice pile, improving the stability of the feeding pipe 224 in absorbing rice.

[0020] See Figure 1-3 As shown, a C-shaped elongated flat cover 3 is fixedly connected to the feeding rack 221 facing the dryer body 1. The flat cover 3 is fastened to the part of the feeding conveyor belt 2 near the feeding pipe 223. The flat cover 3 is parallel to the conveying direction of the feeding conveyor belt 2, and the bottom end of the flat cover 3 abuts against the conveyor belt. The top of the flat cover 3 has a through flat groove 31, which is perpendicular to the conveying direction of the feeding conveyor belt 2. A flat plate 32 is inserted into the flat groove 31, extending to the feeding conveyor belt 2. Both ends of the flat plate 32 abut against the flat cover, and the flat plate 32 is perpendicular to the flat cover 3. The feeding pipe 223 extends into the flat cover 3, and the opening of the feeding pipe 223 away from the feed hopper 225 is located on the side of the flat plate 32 away from the dryer body 1. A lifting assembly 4 is provided between the flat plate 32 and the flat cover 3. The lifting assembly 4 includes a lifting rod 41 fixedly connected to the top of the flat cover 3. The lifting rod 41 is perpendicular to the top surface of the flat cover 3. A lifting sleeve 42 is fitted on the lifting rod 41. A lifting bolt 43 is connected to the circumferential side of the lifting sleeve 42. After the lifting bolt 43 is tightened, it is pressed against the circumferential side of the lifting rod 41. The lifting sleeve 42 is fixedly connected to the top surface of the lifting plate through a matching rod. One end of the matching rod is fixedly connected to the circumferential side of the lifting sleeve 42, and the other end is bent and fixedly connected to the top of the flat plate 32. The lifting assembly 4 drives the flat plate 32 to move in a straight line towards or away from the feeding conveyor belt 2, thereby realizing the adjustment of the distance between the flat plate 32 and the feeding conveyor belt 2, so that the workers can dry the rice according to the expected thickness of the rice grains, and improve the applicability of the feeding assembly 21.

[0021] See Figure 1-3As shown, the hot air duct 5 is suspended above the feeding conveyor belt 2. The hot air duct 5 is parallel to the conveying direction of the feeding conveyor belt 2. The hot air duct 5 is connected to the blowing duct 52 in the direction of the feeding conveyor belt 2. The diameter of the blowing duct 52 is smaller than the diameter of the hot air duct 5. The blowing duct 52 is aligned with the feeding conveyor belt 2. Multiple blowing ducts 52 are provided and are evenly distributed along the hot air duct 5.

[0022] See Figure 1-3 As shown, a long strip of hot air baffle 6 is installed between multiple air blowing pipes 52 and the feeding conveyor belt 2. The hot air baffle 6 is connected to the portion of the feeding conveyor belt 2 located in the drying chamber 11. A fixing rod is installed between the hot air baffle 6 and the hot air pipes 5. One end of the fixing rod is fixedly connected to the hot air baffle 6, and the other end is fixedly connected to the pipe body of the hot air pipe 5. Multiple fixing rods are provided and are evenly distributed between the hot air baffle 6 and the hot air pipe 5. Multiple wide-diffusing holes 61 are opened on the hot air baffle 6 and are evenly distributed on the hot air baffle 6. The hot air baffle 6 simultaneously blocks the openings of the multiple air blowing pipes 52 toward the feeding conveyor belt 2. When the hot air baffle 6 and the wide-diffusing holes 61 are used together, the hot air blown out of the air blowing pipes 52 can act more evenly near the feeding conveyor belt 2, preventing the rice grains on the feeding conveyor belt 2 from being locally overheated and bursting, improving the safety during drying, reducing the occurrence of defective products, and improving the stability of use.

[0023] See Figure 1-3 As shown, the conveyor belt has ventilation holes 9, each with a diameter of 1 mm. Multiple ventilation holes 9 are evenly distributed on the feeding conveyor belt 2. A blower 7 is located at the bottom of the feeding conveyor belt 2, blowing towards the hot air pipe 52. The blower 7 is not perpendicular to the hot air pipe 52. The ventilation holes 9 allow the feeding conveyor belt 2 to have good air permeability. Since the hot air pipe 52 blows downwards, the blower 7 can redirect the hot air moving below the feeding conveyor belt 2 back upwards onto the rice grains. This avoids one-sided heating of the rice grains, improving the uniformity of heating and the drying effect. Furthermore, it reuses the hot air, reducing heat waste.

[0024] See Figure 1-3 As shown, a C-shaped lead-out plate 8 is provided at the end of the feeding conveyor belt 2 in the drying chamber 11. The lead-out plate 8 is fixedly connected to the inner wall of the drying chamber 11 by an auxiliary rod. One end of the lead-out plate 8 abuts against the bottom of the end of the feeding conveyor belt 2, and the other end is inclined towards the ground and passes through the discharge port 112.

[0025] One specific application of this embodiment is: In use, workers use large equipment to transport a large quantity of damp rice to the feed pipe 224 at once. Then, the workers insert the feed pipe 224 into the rice pile and turn on the vacuum pump 222. After the vacuum pump 222 generates negative pressure, it sucks the rice into the feed hopper 225 through the feed pipe 224. The expansion hood 2231 increases the effective range of the feed pipe 224.

[0026] Rice in the feeding hopper 225 is fed through the feeding pipe 223 under the action of gravity. After being fed into the feeding conveyor belt 2 through the feeding pipe 223, rice grains will accumulate on the feeding conveyor belt 2. When the accumulated rice grains pass under the spreading plate, the spreading plate will spread the rice grains flat according to the height set by the lifting component 4. When adjusting the lifting component 4, the worker first loosens the lifting bolt 43, and then slides the lifting sleeve 42 according to the designed spacing height. The lifting sleeve 42 drives the spreading plate to move through the cooperating rod. When it reaches the appropriate position, the worker tightens the lifting bolt 43. The lifting bolt 43 keeps the spreading plate at the predetermined height position.

[0027] During the process of spreading the rice on the flat plate, the spreading cover, which is in contact with the conveyor belt, can block the rice grains moving to both sides and prevent them from falling. After the rice grains are transported out of the spreading cover, the thickness of the rice grains on the feeding conveyor belt 2 remains consistent, and they enter the drying chamber 11 through the feed inlet 111.

[0028] After the rice grains enter the drying chamber 11, the heat generated by the industrial hot air blower 51 is transported to the hot air pipe 5. The hot air pipe 5 blows hot air simultaneously onto the feeding conveyor belt 2 through multiple air blowers 52. The hot air baffle 6 blocks the hot air, ensuring that the hot air evenly raises the temperature of the feeding conveyor belt 2, so that the rice on the feeding conveyor belt 2 is heated evenly. The blower 7 placed below the conveyor belt blows the hot air from the bottom of the drying chamber 11 back onto the feeding conveyor belt 2, so that the rice grains on the feeding conveyor belt 2 are dried on both sides. After drying, the rice falls from the end of the feeding conveyor belt onto the guide plate 8, and then exits from the drying chamber 11 through the guide plate 8.

[0029] In summary, the above steps effectively reduced the number of times workers needed to add rice, thus lowering their workload.

[0030] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
