The turning components of existing grain drying machines are complex in structure, inconvenient to operate, and costly to maintain. This grain turning rake for a grain drying machine aims to address these problems, providing a device with a simple structure, easy operation, and effective turning effect, thereby improving the efficiency and quality of grain drying.

[0030] See also Figure 1-4 , the utility model provides a technical solution:

[0031] A grain turning rake for a grain drying machine comprises a U-shaped base plate 1, the four corners of the lower end of the U-shaped base plate 1 are fixedly connected to pulleys 2, the middle part of the rear end of the U-shaped base plate 1 is fixedly connected to two fixed blocks 3, the inner sides of the two fixed blocks 3 are movably connected to a connecting rod 4, the other end of the connecting rod 4 is fixedly connected to a handle 5, and the right end of the handle 5 is provided with a control button 6, the upper left and upper right parts of the U-shaped base plate 1 are fixedly connected to side plates 7, the left end of the left side plate 7 is fixedly connected to a rotating motor 8, the rotating motor 8 passes through the left side plate 7 and is fixedly connected to a first rotating block 9, the left end of the right side plate 7 is movably connected to 100 through a bearing, the left end of the support column 10 is fixedly connected to a second rotating block 11, the outer surfaces of the first rotating block 9 and the second rotating block 11 are fixedly connected to five movable rods 12, and the outer sides of the five movable rods 12 are fixedly connected to a number of grain turning rakes 13.

[0032] Through the above scheme: the operator pushes the entire device through the handle 5, and easily moves it to the grain drying position with the help of the pulley 2 at the lower end of the U-shaped bottom plate 1, and then presses the control button 6 on the handle 5 to start the rotating motor 8. The rotating motor 8 drives the first rotating block 9 to rotate, and the first rotating block 9 drives the second rotating block 11 to rotate synchronously through five movable rods 12. Since the second rotating block 11 is movably connected through the bearing 100 at the left end of the right side plate 7, it can ensure smooth rotation. During the rotation process, several grain turning rakes 13 on the outer side of the movable rod 12 rotate accordingly, thereby turning the grain. The movable connection between the two fixed blocks 3 and the connecting rod 4 facilitates the adjustment of the angle of the handle 5 to adapt to different operating requirements.

[0033] In this embodiment, the fixed block 3 and the connecting rod 4 are connected by hinge; the rotating motor 8 is electrically connected to the control button 6; the first rotating block 9 and the second rotating block 11 are the same size and shape; the movable rods 12 are distributed at equal intervals on the first rotating block 9 and the second rotating block 11; a number of grain turning rakes 13 are distributed at equal distances on the outer sides of the five movable rods 12; the movable rods 12 and the grain turning rakes 13 are connected by welding, and the welding points are polished.

[0034] The above solution adopts an articulated connection between the fixed block 3 and the connecting rod 4, allowing the connecting rod 4 to flexibly rotate relative to the fixed block 3, thereby facilitating the operator to adjust the angle of the handle 5 according to the actual operation situation, thereby providing a more comfortable and convenient operation experience. When the control button 6 is pressed, it sends a command to the rotary motor 8 through an electrical connection, starting the rotary motor 8. The operation of the rotary motor 8 drives the first rotary block 9 to rotate. Since the first and second rotary blocks 9 and 11 are of the same size and shape, they can ensure synchronous and smooth rotation. The first and second rotary blocks 9 and 11 drive the equally spaced movable rods 12 to rotate, so that the force applied to each movable rod 12 is relatively uniform, ensuring the stability of rotation. The grain turning rakes 13, which are distributed on the outer side of the movable rods 12 and are equidistant from each other, can evenly turn the grain driven by the movable rods 12, ensuring uniform grain drying. The movable rods 12 and the grain turning rakes 13 are connected by welding, which ensures the firmness of the connection. The polishing treatment of the weld reduces resistance and stress concentration, making the grain turning rakes 13 smoother when turning the grain and reducing the possibility of wear and damage.

[0035] It should be noted that the present invention is a grain turning rake for a grain drying machine. During use, first, the operator pushes the device through the handle 5, and the pulleys 2 at the four corners of the lower end of the U-shaped bottom plate 1 enable the device to move easily. After reaching the grain drying position, the control button 6 at the right end of the handle 5 is pressed to start the rotating motor 8 at the left end of the left side plate 7. The rotating motor 8 drives the first rotating block 9 that runs through the left side plate 7 to rotate. The first rotating block 9 drives the second rotating block 11 to rotate synchronously through five movable rods 12. The second rotating block 11 achieves stable rotation through the bearing 100 at the left end of the right side plate 7. As the movable rod 12 rotates, several grain turning rakes 13 fixedly connected to its outer side face turn the grain. Due to the distribution design of the movable rod 12 and the grain turning rake 13, uniform and effective grain turning can be achieved. During use, the angle of the handle 5 is conveniently adjusted through the hinged connection between the two fixed blocks 3 and the connecting rod 4 to adapt to different operating requirements.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
