DETAILED DESCRIPTION

[0032] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0033] In the present application, without making the opposite statement, the orientation words contained in the terms such as "up, down, inside, outside" only represent the orientation of the term in the conventional use state, or the common name understood by the person skilled in the art, and should not be regarded as a limitation of the term.

[0034] Reference Figures 1-6As shown, an agricultural rice drying and turning device is disclosed. The device includes a drying box 100 and a drying board 103 for drying rice, which is slidably disposed in the drying box 100. A turning mechanism 200 is provided above the drying board 103 in the drying box 100. The turning mechanism can move back and forth along the drying box 100 and can rotate to spread and turn the rice drying on the drying board 103. The turning mechanism 200 includes a reciprocating rotating roller 204, multiple sets of turning plates 205 fixedly disposed at intervals on the surface of the rotating roller 204, and a rotating component 300 that drives the rotating roller 204 to rotate while moving.

[0035] In use, the rice to be dried is evenly spread on the drying plate 103. The drive system of the turning mechanism 200 is activated. Under the action of the rotating component 300, the rotating roller 204 is driven to move back and forth along a predetermined track inside the drying box 100, while simultaneously rotating. As the rotating roller 204 moves and rotates, multiple sets of turning plates 205 fixed on its surface continuously contact the rice on the drying plate 103. During the movement, the turning plates 205 spread the rice evenly, ensuring that each grain of rice is fully dried. At the same time, the turning action of the turning plates 205 effectively turns the rice over, allowing both the top and bottom sides of the rice to be dried evenly, thereby improving drying efficiency and quality. The automated operation of the turning mechanism 200 ensures that the rice is fully turned over during the drying process, avoiding localized mold or spoilage caused by prolonged stillness, thus improving the drying quality.

[0036] Reference Figures 4-6 As shown, the flipping mechanism 200 further includes: a reciprocating lead screw 202, a threaded block 203, and a limiting rod 206; wherein, the reciprocating lead screw 202 is rotatably provided on the inner side wall of the drying box 100 and the limiting rod 206 is fixedly provided; a rotary motor 201 with its output shaft horizontally arranged and fixedly connected to the reciprocating lead screw 202 is fixedly provided on the drying box 100; a threaded block 203 is threadedly sleeved on the reciprocating lead screw 202; another threaded block 203 is slidably sleeved on the limiting rod 206; a rotating roller 204 is rotatably provided between the two threaded blocks 203; and a rotating assembly 300 is provided on the side wall of the drying box 100 to drive the rotating roller 204 to rotate when it moves.

[0037] When it is necessary to turn the rice on the drying rack 103, the rotary motor 201 is first started. The output shaft of the rotary motor 201 is horizontally set and fixedly connected to the reciprocating lead screw 202. Therefore, the rotation of the rotary motor 201 will drive the reciprocating lead screw 202 to rotate. Since the reciprocating lead screw 202 is threaded with a threaded block 203, and another threaded block 203 is slidably fitted on the limiting rod 206, when the reciprocating lead screw 202 rotates, the threaded block 203 will move back and forth along the inner side wall of the drying box 100 under the guidance of the reciprocating lead screw 202 and the limiting rod 206. A rotating roller 204 is rotatably provided between the two threaded blocks 203. Therefore, when the threaded block 203 moves, it will drive the rotating roller 204 to move together. At the same time, since the side wall of the drying box 100 is provided with a rotating component 300 that drives the rotating roller 204 to rotate when it moves, the rotating roller 204 will also rotate during the movement.

[0038] Reference Figures 5-6 As shown, the rotating assembly 300 includes a first rack 301 and a gear 302; the first rack 301 is fixedly provided on the inner side wall of the drying box 100, and the gear 302 that meshes with the first rack 301 is fixedly sleeved on the rotating shaft of the rotating roller 204.

[0039] In the above scheme, when the flipping mechanism 200 is working, the rotating roller 204 will move back and forth along the inner wall of the drying box 100 under the drive of the threaded block 203. During the movement of the rotating roller 204, the gear 302 fixedly sleeved on its rotating shaft will mesh with the first rack 301 fixedly installed on the inner wall of the drying box 100. Due to the meshing relationship between the gear 302 and the first rack 301, when the rotating roller 204 moves, the gear 302 will be driven by the first rack 301 to rotate, thereby driving the rotating roller 204 to rotate.

[0040] Reference Figures 2-3 As shown, the drying box 100 is equipped with a filter mechanism 500 located below the drying board 103 for sieving the dried rice and filtering out the mud and fallen leaves.

[0041] In the above scheme, the filtration mechanism 500 is located below the drying plate 103. When the rice on the drying plate 103 falls into the filtration mechanism 500, the filtration mechanism 500 will screen and filter the rice, leaving impurities such as soil and fallen leaves on the filtration mechanism 500, while the clean rice will fall into the collection device below or continue to enter the subsequent processing process.

[0042] Reference Figures 2-3 As shown, the drying box 100 is equipped with a drive mechanism 400 that drives the drying plate 103 to move so that the dried rice on the drying plate 103 falls into the filter mechanism 500.

[0043] In the above scheme, when the rice on the drying plate 103 is dried to the desired degree, the drive mechanism 400 can be activated to drive the drying plate 103 to move so that the dried rice on the drying plate 103 falls into the filter mechanism 500 below. With the addition of the drive mechanism 400, the automatic movement of the drying plate 103 and the automatic collection and processing of rice are realized, which improves the automation level of the entire drying and turning device.

[0044] Reference Figure 3 and Figure 5 As shown, the driving mechanism 400 includes: a driving motor 401, a driving gear 402, and a second rack 403; wherein, the second rack 403 is fixedly provided on the side wall of the drying board 103, and the side wall of the drying box 100 is provided with a clearance groove 404 for the drying board 103 and the second rack 403 to slide, the driving motor 401 is fixedly provided on the drying box 100, and the output shaft of the driving motor 401 is horizontally arranged and the top end is fixedly provided with a driving gear 402 that meshes with the second rack 403.

[0045] In the above scheme, when it is necessary to move the drying plate 103 to let the dried rice fall into the filtration mechanism 500, the drive motor 401 is first started. The output shaft of the drive motor 401 is horizontally set and the top is fixedly equipped with a drive gear 402, while the side wall of the drying plate 103 is fixedly equipped with a second rack 403. When the drive motor 401 is started, the drive gear 402 will mesh with the second rack 403. Driven by the drive gear 402, the second rack 403 will slide along the clearance groove 404 opened on the side wall of the drying box 100, thereby realizing the movement of the drying plate 103. As the drying plate 103 moves, the dried rice on it will fall into the filtration mechanism 500 below.

[0046] Reference Figures 3-5 As shown, the filtration mechanism 500 includes: a filter plate 501, spring columns 505, and a vibrating element; wherein, spring columns 505 are fixedly arranged at intervals on the inner sidewalls of the drying box 100 that are far apart from each other, the top of the spring column 505 is fixedly arranged with the filter plate 501, and the drying box 100 is provided with a vibrating element for driving the filter plate 501 to vibrate to prevent the filter plate 501 from clogging.

[0047] When the rice on the drying plate 103 dries and falls into the filtration mechanism 500, it first falls onto the filter plate 501. The filter plate 501 sieves the rice, leaving impurities such as mud and fallen leaves on the filter plate 501. When the clean rice falls onto the filter plate 501, the vibrating component drives the filter plate 501 to vibrate, thereby shaking off the impurities attached to the filter plate 501. The design of the vibrating component effectively prevents the filter plate 501 from clogging, ensuring the continuity and efficiency of filtration.

[0048] Reference Figure 3As shown, the vibrating component includes a rotating shaft 502 and a cam 503; the rotating shaft 502 is rotatably passed through the drying box 100, and a plurality of cams 503 are fixedly sleeved on the rotating shaft 502 at intervals, which are in contact with the surface of the filter plate 501. The rotating shaft 502 is connected to the output shaft of the drive motor 401 through a transmission belt 504.

[0049] In the above scheme, when the drive mechanism 400 drives the drying plate 103 to retract and drop the dried rice onto the filter plate 501, the output shaft of the drive motor 401 is connected to the rotating shaft 502 that rotates through the drying box 100 via the transmission belt 504. Therefore, when the drive motor 401 starts, it drives the rotating shaft 502 to rotate. Multiple cams 503 are fixedly mounted on the rotating shaft 502 at intervals, and these cams 503 contact the surface of the filter plate 501. When the rotating shaft 502 rotates, the cams 503 rotate accordingly and periodically apply pressure to the filter plate 501. Under the pressure of the cams 503, the filter plate 501 vibrates. This vibration helps to shake off impurities such as soil and fallen leaves attached to the filter plate 501, thereby ensuring the filtration effect.

[0050] Reference Figures 1-2 As shown, the bottom surface of the drying box 100 is fixedly provided with an inclined guide box 104 below the filter plate 501.

[0051] In the above scheme, after the rice on the filter plate 501 is screened, the clean rice falls into the guide box 104 located below it. The bottom surface of the guide box 104 is inclined, which helps the rice to slide smoothly and be collected. At the same time, the design of the guide box 104 can also prevent the rice from scattering or overflowing during the collection process.

[0052] Reference Figures 1-2 As shown, the bottom surface of the guide box 104 is symmetrically and fixedly provided with multiple sets of support legs 101, and each set of support legs 101 is fixedly provided with casters 102 on its bottom surface.

[0053] In the above scheme, the entire drying and turning device is fixed to the ground by multiple sets of support legs 101. Each set of support legs 101 is equipped with casters 102 on its bottom surface, allowing the device to be easily moved and positioned. When it is necessary to move the device or adjust its position, it can be done by operating the casters 102. The design of the casters 102 allows the device to move flexibly under different ground conditions, while ensuring the stability and safety of movement.

[0054] In summary, the rice drying and turning device provided by this utility model allows for the even spreading of harvested rice onto the drying plate 103 during use. The rotary motor 201 is started, and its output shaft drives the reciprocating screw 202 to rotate. The threaded block 203 moves along the threaded screw 202 and simultaneously slides along the limiting rod 206, enabling the rotating roller 204 and its flipping plate 205 to reciprocate within the drying box 100. When the rotating roller 204 moves, its gear 302 meshes with the first rack 301 on the inner wall of the drying box 100, driving the roller 204 to rotate, which in turn drives the flipping plate 205 to rotate. During rotation, the flipping plate 205 continuously spreads and turns the rice on the drying plate 103, ensuring even drying and improving drying efficiency. After the rice on the drying plate 103 is dried, the drive motor 401 is started. The output shaft of the drive motor 401 drives the drive gear 402 to rotate, which meshes with the second rack 403 on the side wall of the drying plate 103. The drying plate 103 is driven to slide along the clearance groove 404. The dried rice falls from the drying plate 103 onto the filter plate 501 of the filter mechanism 500. The filter plate 501 is connected to the inner side wall of the drying box 100 through the spring column 505 and has a certain elasticity. It can filter out impurities such as mud and fallen leaves from the rice. At the same time, the drive motor 401 also drives the rotating shaft 502 to rotate through the transmission belt 504. The cam 503 on the rotating shaft 502 contacts the surface of the filter plate 501. As the rotating shaft 502 rotates, the cam 503 continuously hits the filter plate 501, producing a vibration effect. This vibration can prevent the filter plate 501 from clogging, ensuring that the rice and impurities are separated smoothly. The filtered rice falls into the feed box 104. Because the feed box 104 is tilted, the rice can slide smoothly to the bottom.

However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0056] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0057] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
