Description

Technical Field

[0001] This utility model relates to the field of drying technology, and more specifically, to a rice drying device based on a drying room. Background Technology

[0002] In agricultural production, rice needs to be dried after harvest to reduce its moisture content, making it easier to store and process. Traditional rice drying methods mostly rely on natural sun-drying or specialized drying equipment. Specialized drying equipment is expensive, while natural sun-drying is greatly affected by weather and is inefficient. Meanwhile, tobacco curing barns, as common facilities in tobacco planting and processing, have good airtightness and temperature control capabilities. If their space and heat resources can be rationally utilized during periods of downtime, the cost of rice drying can be effectively reduced.

[0003] Chinese patent CN202120231295.9 discloses a rice seed drying system based on a tobacco curing barn. The system includes a barn body, a temperature generating device for heating, a temperature monitoring device for temperature monitoring, a drying device for laying rice seeds, and multiple exhaust devices. The drying device includes a support frame, a permeable drying platform for laying rice seeds on the support frame, and an airtight baffle forming an air guide cavity with the drying platform. An air outlet device is located within the air guide cavity. This patent achieves rice seed drying by integrating existing tobacco curing barn assembly. However, in this patent, after the rice is laid, the bottom layer or thicker areas may retain moisture due to insufficient heating. This difference in moisture content is more pronounced when the rice is laid thickly, ultimately affecting the overall quality of the dried rice. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and propose a rice drying device based on a drying room. This device ensures the uniformity of rice drying, avoids differences in dryness and moisture, reduces problems such as rice cracking or mold caused by uneven drying, and improves rice quality.

[0005] To achieve the above objectives, this solution provides a rice drying device based on a drying barn, comprising a drying barn, a rice-carrying component, and a pusher assembly. The rice-carrying component is located at the bottom of the drying barn, and the pusher assembly is located above the rice-carrying component. The pusher assembly includes a crossbeam, which is hung on the inner wall of the drying barn. A slide rail is fixedly connected to the bottom outer wall of the crossbeam, and a slider is slidably connected to the slide rail. A drive mechanism is fixedly connected to one outer wall of the slide rail, and the power output end of the drive mechanism is connected to the slider. A horizontal plate is connected to the bottom of the slider, and multiple push rods facing the rice-carrying component are fixed on the horizontal plate.

[0006] In this technical solution, the curing barn is an existing technology used for flue-cured tobacco. The curing barn can provide a heat source for drying. During the drying operation, the rice is spread on the rice-carrying component. The curing barn provides the heat source required for drying, and hot air flows in the curing barn to dry the rice. At the same time, the drive mechanism is activated, which drives the slider to slide in the slide rail, thereby driving the horizontal plate and push rod to move back and forth along the slide rail. During the movement, the push rod plays a role in turning the rice, avoiding the rice from piling up, effectively ensuring the uniformity of rice drying, reducing problems such as rice cracking or mold caused by uneven drying, and improving the quality of rice.

[0007] As a preferred embodiment, the curing barn is equipped with vertical and longitudinal tobacco hanging beams. The vertical and longitudinal tobacco hanging beams are arranged perpendicularly to each other, forming the internal support frame of the curing barn. The crossbeams are hung on the longitudinal tobacco hanging beams. The vertical and longitudinal tobacco hanging beams are the original internal structure of the curing barn and are existing technology. By utilizing the original tobacco hanging beams inside the curing barn to form the support frame, there is no need to build an additional complex support structure, thus saving internal space of the curing barn.

[0008] As a preferred embodiment, in order to drive the slider to move, a lead screw is rotatably connected to the inner wall of the slide rail, the slider is provided with a threaded hole that matches the lead screw, the lead screw is threadedly connected to the slider, and the power output end of the drive mechanism is connected to one end of the lead screw to drive the lead screw to rotate.

[0009] As a preferred embodiment, the grain-carrying assembly includes a support frame and a leak-proof net, wherein the leak-proof net is disposed on the support frame and has a mesh structure that allows hot air to enter the rice from the bottom for drying.

[0010] As a preferred embodiment, the support frame includes a frame and support legs. The support legs are vertically arranged at the bottom of the frame. The frame supports the anti-leakage net. The support legs of the support frame can raise the frame and the anti-leakage net it carries, so that hot air can enter smoothly from the bottom.

[0011] As a preferred embodiment, the support frame is provided with multiple tobacco clips, the array of tobacco clips is laid flat on the support frame, and the bottom of the anti-leakage net is attached to the top of the tobacco clips. By setting the tobacco clips, the original tobacco curing function of the curing barn is retained.

[0012] As a preferred embodiment, the mesh size of the anti-leakage net is smaller than the grain size of rice, which can effectively prevent rice from leaking out.

[0013] As a preferred embodiment, to further enhance heat exchange and avoid localized heat accumulation or moisture retention in the rice, multiple push rods are arranged in an array on a horizontal plate. Each push rod has a hollow structure and is interconnected. The outer wall of each push rod has ventilation holes. An air supply pipe connected to each push rod is installed inside the horizontal plate. The air supply inside the horizontal plate is connected to an external air source, delivering airflow to the interconnected push rods. The airflow exits through the ventilation holes of the push rods and blows towards the rice layer, accelerating the evaporation of moisture from the rice surface and improving drying efficiency. The array distribution of the push rods on the horizontal plate ensures complete coverage of the rice surface. Each push rod moves back and forth at a uniform speed along a slide rail under the drive of a driving mechanism. The moving speed can be adjusted by the control system according to the rice thickness and drying stage to balance turning efficiency and the risk of rice damage.

[0014] As a preferred embodiment, the top of the longitudinal smoke-hanging beam is equipped with a diffuser plate, which can disperse the hot air and make the hot air cover the rice below more evenly, avoiding localized excessively high or low temperatures.

[0015] As a preferred embodiment, the air diffuser is a plate with a ventilation structure on its surface. The ventilation structure is in the form of a hollow or array of openings to ensure that hot air can pass through smoothly and be evenly dispersed.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model discloses a rice drying device based on a drying room. The push rod of the push plate assembly moves back and forth under the drive of the drive mechanism, lead screw and other components, which can turn and flatten the rice, avoid the rice from piling up too thickly, and ensure that all parts of the rice can fully contact the hot air. The airflow delivered by the air supply pipe is discharged from the ventilation hole of the push rod, which further promotes the turning of the rice and the evaporation of moisture, effectively ensuring the uniformity of rice drying, reducing problems such as rice cracking or mold caused by uneven drying, and improving the quality of rice.

[0017] 2. This utility model utilizes the existing tobacco hanging beams inside the curing barn to form a supporting frame, eliminating the need for additional complex supporting structures and saving internal space. Components such as the grain-carrying assembly, air diffuser, and pusher assembly are arranged in functional layers, with each component compactly arranged and not interfering with the others, making full use of the three-dimensional space of the curing barn.

[0018] 3. The air diffuser of this utility model can evenly disperse the hot air in the drying room through the ventilation structure such as the hollow or array of openings on the surface, so as to avoid the hot air from concentrating and causing the rice to be too dry or too wet in some places.

[0023] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example 1: like Figures 1 to 4As shown, this embodiment provides a rice drying device based on a drying barn, including a drying barn 1, a rice-carrying component 2, and a pusher plate component 4. The rice-carrying component 2 is located at the bottom of the drying barn 1, and the pusher plate component 4 is located above the rice-carrying component 2. The pusher plate component 4 includes a crossbeam 401, which is hung on the inner wall of the drying barn 1. A slide rail 402 is fixedly connected to the bottom outer wall of the crossbeam 401, and a slider 403 is slidably connected to the slide rail 402. A drive mechanism 405 is fixedly connected to one side outer wall of the slide rail 402, and the power output end of the drive mechanism 405 is connected to the slider 403. A horizontal plate 406 is connected to the bottom of the slider 403, and a plurality of push rods 407 facing the rice-carrying component 2 are fixed on the horizontal plate 406.

[0024] In this embodiment, the surface of the baking oven 1 is coated with an anti-rust coating to extend its service life and adapt to the high-temperature environment inside the baking oven 1.

[0025] In this embodiment, the end of the push rod 407 is designed with a smooth curved surface to avoid damage to the grains when turning the rice.

[0026] In this embodiment, the drive mechanism 405 is a servo drive motor, whose control end is connected to an external controller to realize the adjustable reciprocating frequency of the slider 403. The drive mechanism 405 is provided with a high-temperature resistant protective cover to prevent the high temperature in the baking oven 1 from affecting the normal operation of the drive mechanism 405. The two ends of the slide rail 402 can also be provided with stroke limit switches, which are electrically connected to the drive mechanism 405 to limit the movement range of the slider 403 and prevent overtravel.

[0027] Specifically, the interior of the curing barn 1 is provided with a vertical smoke-hanging beam 101 and a longitudinal smoke-hanging beam 102. The vertical smoke-hanging beam 101 and the longitudinal smoke-hanging beam 102 are arranged perpendicularly to each other to form a support frame inside the curing barn 1. The crossbeam 401 is hung on the longitudinal smoke-hanging beam 102.

[0028] In this embodiment, both the vertical smoke hanging beam 101 and the longitudinal smoke hanging beam 102 are made of high-strength alloy material, which has good load-bearing performance and high temperature resistance. Their spacing is reasonably set according to the size of the drying room 1 and the actual drying needs to ensure the stability of the overall structure.

[0029] Specifically, a lead screw 404 is rotatably connected to the inner wall of the slide rail 402, and a threaded hole matching the lead screw 404 is provided on the slider 403. The lead screw 404 and the slider 403 are threadedly connected, and the power output end of the drive mechanism 405 is connected to one end of the lead screw 404 to drive the lead screw 404 to rotate.

[0030] In this embodiment, the drive mechanism 405 is activated, which drives the lead screw 404 to rotate. Since the lead screw 404 is threadedly connected to the slider 403, the slider 403 slides in the slide rail 402, thereby driving the horizontal plate 406 and the push rod 407 to move back and forth along the slide rail 402. During the movement, the push rod 407 plays a turning role on the rice below.

[0031] Specifically, the grain-carrying component 2 includes a support frame 201 and a leak-proof net 203, with the leak-proof net 203 disposed on the support frame 201.

[0032] Specifically, the support frame 201 includes a frame and support legs, the support legs are vertically arranged at the bottom of the frame, and the frame supports the anti-leakage net 203.

[0033] In this embodiment, the frame is welded from rectangular steel pipes, and the height of the support legs can be adjusted according to actual needs. The support rods are evenly distributed at the bottom of the frame and fixedly connected to the support legs, which further enhances the overall load-bearing capacity of the support frame 201 and prevents deformation when carrying rice.

[0034] Specifically, the mesh size of the leak-proof net 203 is smaller than the grain size of rice.

[0035] Specifically, a diffuser plate 3 is provided on the top of the longitudinal smoke-hanging beam 102.

[0036] In this embodiment, the air diffuser plate 3 is made of high-temperature resistant metal material, and its size matches the size of the longitudinal smoke hanging beam 102 to ensure that hot air can pass through smoothly and achieve uniform dispersion.

[0037] In this embodiment, the existing tobacco hanging beams inside the curing barn 1 are used to form a support frame, eliminating the need for additional complex support structures and saving internal space. Components such as the grain-carrying component 2, the air-diffusing plate 3, and the pusher plate component 4 are arranged in functional layers, with each component compactly arranged and not interfering with the others, making full use of the three-dimensional space of the curing barn.

[0038] Specifically, the air diffuser plate 3 is a plate with a ventilation structure on its surface, and the ventilation structure is in the form of a hollow or array of openings.

[0039] In this embodiment, the drying chamber 1 provides the heat source required for drying. Hot air flows inside the drying chamber. The air diffuser 3 at the top of the longitudinal hanging smoke beam 102 disperses the hot air through ventilation structures such as perforations or array openings on the surface, so that the hot air covers the rice below more evenly and avoids local temperatures that are too high or too low.

[0040] In this embodiment, the leak-proof mesh 203 has good corrosion resistance and toughness, is easy to disassemble and clean, and avoids the accumulation of rice residue and impurities.

[0041] Example 2: This embodiment is similar to Embodiment 1, except that, as Figure 3 , 4 As shown, in this embodiment, multiple push rods 407 are arrayed on a horizontal plate 406. Each push rod 407 has a hollow structure and is interconnected. The outer wall of each push rod 407 has a ventilated round hole. An air supply pipe 408 connected to each push rod 407 is provided inside the horizontal plate 406.

[0042] In this embodiment, the push rod 407 is made of lightweight alloy material, and its length is designed according to the thickness of the rice laid on the grain-carrying component 2. The ventilation holes are evenly distributed in the bottom area of ​​the push rod 407. The air supply pipe 408 is equipped with a flow regulating valve at the connection end with the external air source, which can adjust the air supply volume according to the drying process.

[0043] In this embodiment, the air supply pipe 408 inside the horizontal plate 406 is connected to an external air source to deliver airflow to each push rod 407 that are interconnected. The airflow is discharged from the vent holes of the push rod 407 and blown toward the rice layer to accelerate the evaporation of moisture on the surface of the rice and improve the drying efficiency.

[0044] Example 3: This embodiment is similar to Embodiment 1, except that, as Figure 2 As shown in this embodiment, the support frame 201 is provided with a plurality of cigarette clips 202, the cigarette clips 202 are laid flat on the support frame 201, and the bottom of the anti-leakage net 203 is attached to the top of the cigarette clips 202.

[0045] In this embodiment, the rice drying device of the present invention is based on the original drying room structure and retains its original tobacco clip 202, so that the device of the present invention can dry rice or tobacco leaves separately, and the two functions do not interfere with each other.
