[0025] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] It is understandable that, referring to Figures 1 to 4 The grain turning and leveling device of the present invention includes a translation mechanism 100, a grain turning mechanism 200 and a grain leveling mechanism 300. The translation mechanism 100 includes a base 110, a first driving member 120 and a first slider 130. The first slider 130 is slidably connected to the base 110, and the first driving member 120 is used to drive the first slider 130 to move horizontally; the grain turning mechanism 200 includes a roller 210, a second driving member 220 and a turning rake 230. The roller 210 is rotatably connected to the first slider 130, and the turning rake 230 is connected to the side wall of the roller 210. The second driving member 220 is used to drive the roller 210 to rotate so that the turning rake 230 turns the grain surface; the grain leveling mechanism 300 includes a leveling plate 310. The leveling plate 310 is connected to the first slider 130. The leveling plate 310 and the roller 210 are arranged at intervals along the moving direction of the first slider 130. The leveling plate 310 is used to level the grain surface.

[0030] During use, the base 110 is fixed to the granary so that the roller 210 and the leveling plate 310 are located above the surface of the grain, and the bottom of the leveling plate 310 is in contact with the surface of the grain. The roller 210 is driven to rotate by the second driving member 220, and the turning rake 230 is driven to rotate. The turning rake 230 can be inserted into the surface of the grain and turn the grain surface during rotation. At the same time, the first slider 130 is driven to move horizontally by the first driving member 120. Since the roller 210 is rotatably connected to the first slider 130 and the leveling plate 310 is connected to the first slider 130, the first slider 130 can drive the roller 210 and the leveling plate 310 to move horizontally. The turning rake 230 is used to turn the grain surface, and the leveling plate 310 is used to scrape the turned grain surface, thereby turning and leveling the grain in the horizontal direction, which can reduce manual labor intensity and improve turning efficiency and turning quality.

[0031] It should be noted that the first driving member 120 can be a motor, a cylinder, an oil cylinder or a linear slide module, etc., as long as it can drive the first slider 130 to move horizontally.

[0032] The second driving member 220 can be a servo motor or a stepping motor, etc., which can drive the roller 210 to rotate.

[0033] The leveling plate 310 and the roller 210 are arranged in sequence along the moving direction of the first slider 130, so that when the first slider 130 moves, the leveling plate 310 can level the grain surface after being turned by the turning rake 230, thereby improving the turning efficiency.

[0034] It is understandable that, referring to Figure 2 and Figure 4 A plurality of turning rakes 230 are provided, and the turning rakes 230 are evenly spaced along the circumference of the rotating roller 210. By providing a plurality of turning rakes 230 and evenly spaced along the circumference of the rotating roller 210, when the rotating roller 210 rotates, the plurality of turning rakes 230 in the circumferential direction can all turn the grain surface, thereby improving the turning efficiency of the grain surface.

[0035] It is understandable that, referring to Figure 2 and Figure 4 The turning rake 230 is provided with a plurality of rake teeth 231, and the plurality of rake teeth 231 are evenly arranged along the axial direction of the rotating roller 210, and the rake teeth 231 extend along the radial direction of the rotating roller 210. The end shape of the rake teeth 231 is conical, and the end diameter of the rake teeth 231 gradually decreases along the axial direction of the rake teeth 231 in the direction away from the rotating roller 210. By evenly arranging multiple rake teeth 231 at intervals along the axial direction of the roller 210, the rake teeth 231 can be used to evenly turn the grain in the axial direction of the roller 210 to improve the turning uniformity, thereby improving the turning quality. Moreover, since the end shape of the rake teeth 231 is conical, the end diameter of the rake teeth 231 gradually decreases along the axial direction of the rake teeth 231 away from the roller 210, which can reduce the resistance of the rake teeth 231 when inserted into the grain surface, which is beneficial for the rake teeth 231 to be inserted into the grain surface. Moreover, the conical surface guides and pushes the grain to move along the outer periphery of the rake teeth 231, which can reduce the damage of the rake teeth 231 to the grain, thereby improving the turning quality.

[0036] It is understandable that, referring to Figure 1 and Figure 2 Annular baffles 240 are provided on both sidewalls of the roller 210, and the turning rake 230 is located between the two annular baffles 240. Since the turning rake 230 is located between the two annular baffles 240, the annular baffles 240 prevent grain from splashing toward the ends of the roller 210, thereby reducing grain splashing and concentrating the grain in the area that the turning rake 230 can contact, thereby improving the turning quality.

[0037] It is understandable that, referring to Figure 1 and Figure 2Two leveling plates 310 are provided. Along the sliding direction of the first slider 130, the two leveling plates 310 are respectively arranged on opposite sides of the rotating roller 210. By arranging the two leveling plates 310 on opposite sides of the rotating roller 210, when the first slider 130 moves horizontally in the forward or reverse direction, the leveling plates 310 on both sides can level the grain surface after turning, thereby enabling the grain surface to be turned repeatedly to improve the turning quality.

[0038] It is understandable that, referring to Figure 2 The bottom surface of the leveling plate 310 is V-shaped. When the leveling plate 310 scrapes the grain, the V-shaped bottom surface of the leveling plate 310 can guide the grain to slide along the inclined surface to the bottom of the leveling plate 310. Moreover, when the leveling plate 310 moves horizontally in the forward or reverse direction, the inclined surfaces on both sides can guide the grain to slide along the inclined surface to the bottom of the leveling plate 310, thereby improving the leveling quality.

[0039] It should be noted that the top surface shape of the flattening plate 310 can be set to an inverted V shape so that the grain splashed onto the top surface of the flattening plate 310 can slide down along the slope, thereby reducing the possibility of grain splashing and accumulating on the flattening plate 310, thereby reducing the loss of grain in the granary.

[0040] It is understandable that, referring to Figure 3 The end of the leveling plate 310 is provided with a mounting block 311. The mounting block 311 defines a first mounting hole 312, through which a first bolt is passed. The mounting block 311 is fixedly connected to the first slider 130 via the first bolt. Tightening the first bolt secures the mounting block 311 to the first slider 130, thereby securing the leveling plate 310 to the first slider 130. Loosening the first bolt allows the leveling plate 310 to be removed from the first slider 130, thereby achieving a detachable connection between the leveling plate 310 and the first slider 130 and facilitating assembly and replacement of the leveling plate 310. Furthermore, the leveling plate 310 can be removed as needed to achieve a single grain turning function.

[0041] It is understandable that, referring to Figure 3 and Figure 4The first slider 130 is rotatably connected to a rotating block 250. The rotating block 250 defines a second mounting hole 251, through which a second bolt is passed. The rotating block 250 is fixedly connected to the end of the roller 210 via the second bolt. Since the rotating block 250 is rotatably connected to the first slider 130, by tightening the second bolt, the roller 210 is fixedly connected to the rotating block 250, and the roller 210 can be rotatably connected to the first slider 130. By loosening the second bolt, the roller 210 can be removed from the rotating block 250, thereby achieving a detachable connection between the roller 210 and the rotating block 250, facilitating the assembly and disassembly of the roller 210. Furthermore, the roller 210 can be removed as needed to achieve a single grain leveling function.

[0042] It should be noted that, referring to Figure 4 Two first sliders 130 can be provided, and the two ends of the roller 210 are rotatably connected to the two first sliders 130 respectively, and the two ends of the leveling plate 310 are respectively connected to the two first sliders 130, so that the roller 210 and the leveling plate 310 are subjected to balanced force during the sliding process, reducing the possibility of the roller 210 and the leveling plate 310 tilting due to the reverse force of the grain during the movement, thereby improving the stability of the grain turning.

[0043] It is understandable that, referring to Figure 2 and Figure 4 The grain leveling mechanism 300 further includes a third driving member 320. The first slider 130 is provided with a vertical support rod 330, which is slidably connected to a second slider 340. The third driving member 320 is used to drive the second slider 340 to move vertically up and down. The leveling plate 310 is connected to the second slider 340, and the roller 210 is rotatably connected to the second slider 340. The third driving member 320 drives the second slider 340 to move vertically up and down, and the second slider 340 drives the leveling plate 310 and the roller 210 to move up and down, thereby adjusting the vertical height position of the leveling plate 310 and the roller 210, and further adjusting the distance between the leveling plate 310 and the grain surface, and between the roller 210 and the grain surface. This can adapt to the turning of grain surfaces of different depths, thereby improving the applicability of the grain turning and leveling device.

[0044] It should be noted that the third driving member 320 can be a cylinder, an oil cylinder or a linear slide module, etc., which can drive the second slider 340 to move vertically up and down.

[0045] Specifically, refer to Figure 2The grain leveling mechanism 300 also includes a distance sensor 350 and a controller. The distance sensor 350 is mounted on the leveling plate 310 and is used to detect the distance between the leveling plate 310 and the grain surface. The distance sensor 350 and the third drive member 320 are both electrically connected to the controller. The distance sensor 350 detects the distance between the leveling plate 310 and the grain surface and feeds this distance information back to the controller. The controller then controls the third drive member 320 to drive the second slider 340 to move vertically upward and downward, thereby adjusting the distance between the leveling plate 310 and the grain surface and between the roller 210 and the grain surface, thereby improving adjustment efficiency and accuracy.

[0046] It should be noted that the first driving member 120 and the second driving member 220 are both electrically connected to the controller, and the controller controls the first driving member 120 and the second driving member 220 to perform corresponding actions.

[0047] The controller may be a single chip microcomputer or a programmable logic controller, etc., and may be capable of controlling the first driving member 120 , the second driving member 220 and the third driving member 320 to perform corresponding actions.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
