Description

Technical Field

[0001] This utility model belongs to the field of rice processing technology, and in particular relates to a continuous dehydration and drying machine for rice processing. Background Technology

[0002] After harvesting, rice typically has a high moisture content, generally between 15% and 25%. If it is not dried in time, it is very easy for rice to mold and spoil, leading to a decline in quality, loss of nutrients, and even rendering it inedible or unprocessable. Traditional rice drying methods mainly include natural sun-drying and simple drying equipment. Natural sun-drying relies on sunlight and good ventilation, which is greatly affected by weather factors. In areas or seasons with frequent rainy weather, rice may not be able to dry sufficiently for a long time, which not only delays the processing cycle but also poses a risk of mold growth. Moreover, natural sun-drying requires a large area and is inefficient, making it difficult to meet the needs of large-scale rice production and processing. Therefore, it is necessary to use a continuous dehydration dryer for rice processing to dry the rice.

[0003] However, existing continuous dehydration dryers for rice processing have difficulty ensuring uniform feeding when rice yield or grain size changes, and the rice may also deviate from its designated path, thus affecting the entire drying process. Utility Model Content

[0004] The purpose of this utility model is to provide a continuous dehydration and drying machine for rice processing. By setting a spacing adjustment mechanism, it solves the problem that existing continuous dehydration and drying machines for rice processing are difficult to ensure uniform feeding when the rice yield or grain size changes, and the rice may also deviate from its designated position, thus affecting the entire drying process.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a continuous dehydration and drying machine for rice processing, including a conveyor belt, on which a spacing adjustment mechanism and a thickness adjustment mechanism are provided;

[0007] A heating module is fixedly connected to the top of the conveyor belt. The spacing adjustment mechanism includes an adjustment component and a limiting component. The adjustment component includes two support plates fixedly connected to the bottom of the conveyor belt. The two support plates are located on the left and right sides of the conveyor belt, respectively. A bidirectional threaded rod is rotatably connected between the two support plates. The front side of the bidirectional threaded rod rotatably passes through the support plate located on the front side and extends to the outside. A motor is fixedly connected to the front side of the conveyor belt located on the front side. The output shaft of the motor is fixedly connected to the bidirectional threaded rod through a coupling.

[0008] Furthermore, two movable plates are threadedly connected to the outer wall of the motor, and a sliding rod is fixedly connected between the two support plates, the sliding rod sliding through the two movable plates.

[0009] Furthermore, two connecting rods are fixedly connected to the sides of the two movable plates that are far apart from each other, and two guide plates are fixedly connected to the sides of the several connecting rods that are close to each other.

[0010] Furthermore, the limiting component includes a rotating groove formed on the front support plate, and a retaining ring is fixedly connected to the outer wall of the bidirectional threaded rod, the outer wall of the retaining ring extending rotatably into the rotating groove.

[0011] Furthermore, the thickness adjustment mechanism includes an I-shaped support frame fixedly connected to the top of the conveyor belt, and a threaded rod is threaded through the central axis of the I-shaped support frame.

[0012] Furthermore, a handle is fixedly connected to the top extension of the threaded rod, and a scraper is fixedly connected to the bottom extension of the threaded rod.

[0013] Furthermore, trapezoidal grooves are fixedly connected to the inner walls of the front and rear sides of the C-shaped support frame, and trapezoidal sliders are fixedly connected to the front and rear sides of the scraper. The front and rear sides of the two trapezoidal sliders slide into the two trapezoidal grooves respectively.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting a spacing adjustment mechanism, when it is necessary to adjust the spacing of the guide plates, the motor can be started as needed. The motor will drive the bidirectional threaded rod to rotate under the action of the rotating groove and the retaining ring. When the bidirectional threaded rod rotates, it will cooperate with the sliding rod to drive the two moving plates closer or further apart. When the two moving plates are closer or further apart, they will be connected by the connecting rod to drive the two guide plates closer or further apart. This allows the feed flow of rice to be controlled, enabling the dryer to better adapt to differences in shape or size, allowing rice of different shapes or sizes to pass through smoothly and avoiding blockage. At the same time, it can also ensure that the rice is evenly distributed on the conveyor belt, improving the equipment's versatility for various rice varieties and expanding the equipment's application range.

[0016] 2. By setting up a thickness adjustment mechanism, when rice needs to be dried, the handle can be turned according to the moisture level of the rice. The handle will drive the threaded rod to rotate. The threaded rod is connected to the C-shaped support frame by threads. So when the threaded rod rotates, it will cooperate with the trapezoidal slide and trapezoidal slider, thereby driving the scraper to move up or down until the appropriate height is adjusted. Then, the rice to be dried is poured onto the conveyor belt and the conveyor belt is started. The rice poured onto the conveyor belt will be flattened by the scraper. The height of the scraper determines the thickness of the rice, which ensures that the rice is heated evenly on the conveyor belt, ensuring the consistency of the drying quality of the whole batch of rice. The heat can be quickly transferred to each grain of rice, thereby shortening the time required for the rice to reach the drying standard.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The adjustment component 21 includes two support plates 211 fixedly connected to the bottom of the conveyor belt 1. The two support plates 211 are located on the left and right sides of the conveyor belt 1, respectively. A bidirectional threaded rod 212 is rotatably connected between the two support plates 211. The front side of the bidirectional threaded rod 212 rotatably passes through the support plate 211 located on the front side and extends to the outside. A motor 213 is fixedly connected to the front side of the conveyor belt 1 located on the front side. The output shaft of the motor 213 is fixedly connected to the bidirectional threaded rod 212 via a coupling. Two movable plates 214 are threadedly connected to the outer wall of the motor 213. A sliding rod 215 is fixedly connected between the support plates 211. The sliding rod 215 slides through two moving plates 214. Two connecting rods 216 are fixedly connected to the sides of the two moving plates 214 that are far apart from each other. Two guide plates 217 are fixedly connected to the sides of the connecting rods 216 that are close to each other. The limiting component 22 includes a rotating groove 221 opened on the front support plate 211. A retaining ring 222 is fixedly connected to the outer wall of the bidirectional threaded rod 212. The outer wall of the retaining ring 222 extends rotatably into the rotating groove 221. By setting the spacing adjustment mechanism 2, the feed flow of rice can be controlled, which can make the dryer better adapt to differences in shape or size, allowing rice of different shapes or sizes to pass through smoothly and avoid blockage. At the same time, it can also ensure that the rice is evenly distributed on the conveyor belt, improve the equipment's versatility for multiple rice varieties, and expand the equipment's application range.

[0028] The thickness adjustment mechanism 3 includes an inverted bracket 301 fixedly connected to the top of the conveyor belt 1. A threaded rod 302 is threaded through the central axis of the inverted bracket 301. A handle 303 is fixedly connected to the top extension of the threaded rod 302, and a scraper 304 is fixedly connected to the bottom extension of the threaded rod 302. Trapezoidal grooves 305 are fixedly connected to the inner walls of the front and rear sides of the inverted bracket 301. Trapezoidal sliders 306 are fixedly connected to the front and rear sides of the scraper 304. The front and rear sides of the two trapezoidal sliders 306 slide into the two trapezoidal grooves 305 respectively. By setting the thickness adjustment mechanism 3, the rice can be heated evenly on the conveyor belt, ensuring the consistency of the drying quality of the whole batch of rice. The heat can be quickly transferred to each grain of rice, thereby shortening the time required for the rice to reach the drying standard.

[0029] A specific application of this embodiment is as follows: In use, the device is first placed in the appropriate position. When drying rice, the handle 303 is turned according to the moisture level of the rice. The handle 303 will drive the threaded rod 302 to rotate. Since the threaded rod 302 is threadedly connected to the U-shaped support frame 301, when the threaded rod 302 rotates, it will cooperate with the trapezoidal slide 305 and the trapezoidal slider 306, thereby driving the scraper 304 to move up or down until the appropriate height is reached. Then, the rice to be dried is poured onto the conveyor belt 1, and the conveyor belt 1 is started. The rice poured onto the conveyor belt 1 will be leveled by the scraper 304, and the height of the scraper 304 determines the thickness of the rice. Then, the motor 213 is started as needed. The motor 213, under the action of the rotating groove 221 and the retaining ring 222, drives bidirectional... When the threaded rod 212 rotates, it cooperates with the sliding rod 215, causing the two moving plates 214 to move closer or further apart. When the two moving plates 214 move closer or further apart, they are connected by the connecting rod 216, which in turn causes the two guide plates 217 to move closer or further apart. This allows control over the rice feed flow, enabling the dryer to better adapt to differences in shape or size, allowing rice of different shapes or sizes to pass smoothly without clogging. It also ensures uniform distribution of rice on the conveyor belt, improving the equipment's versatility for various rice varieties and expanding its application range. When the conveyor belt 1 transports the rice to below the heating module 101, the heating module 101 heats the rice, completing the drying process.
