[0031] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0032] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] See also Figures 1 to 8 , which is a material turnover vehicle of an embodiment of the present invention, includes a frame 10, a lifting assembly 20 installed on the body 10, and a roller conveying assembly 30 slidably connected to the top of the lifting assembly 20; the roller conveying assembly 30 is used to transport the silo 40.

[0035] The vehicle body 10 includes a vehicle body main body 11 , casters 12 mounted at four opposite corners of the bottom surface of the vehicle body main body 11 , and a floor brake 13 mounted at one end of the bottom surface of the vehicle body main body 11 .

[0036] The lifting assembly 20 includes columns 21 installed at four opposite corners inside the vehicle body 11, a lifting plate 22 slidably connected to the columns 21, guide plates 23 connected to the opposite ends of the bottom surface of the lifting plate 22, an adjustment frame 24 slidably connected to the vehicle body 11, and rollers 25 rotatably installed at the opposite ends of the adjustment frame 24; wherein, each guide plate 23 is provided with a guide groove 230, and the longitudinal direction of the guide groove 230 is inclined with respect to the vertical direction; the roller 25 is embedded in the interior of the guide groove 230.

[0037] In this embodiment, the lifting plate 22 moves vertically. Specifically, the lifting plate 22 is connected to the upright column 21 via a guide rail assembly. The movement direction of the adjustment frame 24 is inclined relative to the length of the guide slot 230. In other words, the movement direction of the roller 25 is inclined relative to the length of the guide slot 230. In actual operation, due to the constraints of the guide rail assembly, when the adjustment frame 24 moves, the force exerted by the roller 25 on the guide slot 230 is converted into a vertical force, thereby driving the lifting plate 22 to move vertically.

[0038] In this embodiment, the adjustment frame 24 is generally U-shaped and is connected to the vehicle body 11 via a ball screw pair to achieve sliding adjustment of the adjustment frame 24. Figure 4 and Figure 5 As shown, a fixed nut seat 241 is mounted on the bottom surface of the adjustment frame 24, and a ball screw 242 is rotatably mounted on the vehicle body 11. The ball screw 242 is mated and connected to the fixed nut seat 241 to achieve a sliding connection between the adjustment frame 24 and the vehicle body 11. Furthermore, a corrugated handwheel 243 is mounted on one end of the ball screw 242 to facilitate manual operation of the movement of the adjustment frame 24.

[0039] Furthermore, guide rails 26 are connected to opposite ends of the top surface of the lifting plate 22. The length of the guide rails 26 aligns with the direction of movement of the adjustment frame 24. Limit blocks 27 are also connected to opposite sides of the top surface of the lifting plate 22. Both the guide rails 26 and the limit blocks 27 are used to cooperate with the roller conveyor assembly 30.

[0040] The roller conveyor assembly 30 includes a transverse plate 31 that is slidably connected to the top surface of the lifting plate 22, two roller conveyor belts 32 installed side by side on the top surface of the transverse plate 31, a check valve 33 installed at the inlet end of each roller conveyor belt 32, handles 34 installed on opposite sides of the transverse plate 31, and a transverse handrail 35 installed at one end of the transverse plate 31. Among them, the roller conveyor belt 32 is used to move the silo 40. The moving direction of the transverse plate 31 is consistent with the moving direction of the adjustment frame 24, and the conveying direction of the roller conveyor belt 32 is perpendicular to the moving direction of the adjustment frame 24. According to the actual environment, the handle 34 or the transverse handrail 35 is used to push the transverse plate 31 and the lifting plate 22 to slide relative to each other to adjust the position of the entire roller conveyor assembly 30 to match different equipment for loading and unloading.

[0041] like Figure 3 As shown, sliders 36 are mounted at four opposite corners of the bottom surface of the transverse plate 31. The sliders 36 mate with the guide rails 26 to achieve a sliding connection between the transverse plate 31 and the lifting plate 22. The transverse plate 31 is positioned between the limit blocks 27 on opposite sides of the top surface of the lifting plate 22, and the limit blocks 27 limit the range of movement of the transverse plate 31.

[0042] In actual work, the operation process of the material turnover vehicle is as follows:

[0043] First, a fully loaded silo 40 is placed onto a roller conveyor 32. Next, the entire material transfer vehicle is moved to the equipment's loading docking position. Once in position, the operator manually operates the corrugated handwheel 243 to rotate the ball screw 242. The rotation of the ball screw 242 causes the adjustment frame 24 to slide along the vehicle body 11. Because the rollers 25 mounted on the adjustment frame 24 are embedded in the guide grooves 230, the movement of the adjustment frame 24 is converted into the lifting and lowering motion of the lifting plate 22. By adjusting the height of the lifting plate 22, it can be adapted to equipment of different heights, ensuring that the roller conveyor 32 and the equipment's loading docking position are on the same horizontal plane.

[0044] After the height adjustment of the lifting plate 22 is completed, the operator can push the traverse plate 31 to slide on the lifting plate 22 through the handle 34 or the traverse armrest 35. The movement of the traverse plate 31 will drive the roller conveyor 32 to move together, thereby adjusting the position of the roller conveyor 32 to match the loading docking position of the equipment.

[0045] Next, the operator needs to remove the empty silo 40 from the equipment and transfer it to the empty roller conveyor 32. Then, the operator needs to move the transverse plate 31 again to switch the fully loaded silo 40 to the loading docking position of the equipment. Finally, the fully loaded silo 40 is sent into the equipment to complete the loading operation of the silo 40.

[0046] Furthermore, in this embodiment, a retaining groove 41 is provided on two opposite sides of the bottom of the silo 40; a retaining plate 320 is installed on two opposite sides of the inlet end of each roller conveyor 32, and the retaining plate 320 is matched and embedded in the interior of the retaining groove 41 to limit the silo 40, effectively preventing the silo 40 from tilting, thereby greatly improving stability and safety.

[0047] The above-mentioned material turnover vehicle has a simple structure and is easy to use. The transverse plate 31 is slidably connected to the lifting plate 22. The height of the roller conveyor belt 32 can be adjusted by utilizing the coordinated action of the roller 25 and the guide groove 230. Its flexible lifting and transverse adjustment functions can adapt to equipment of different heights and positions, facilitate precise docking and rapid loading and unloading between equipment of different heights, and greatly improve the smoothness and overall production capacity of the production line.

[0048] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
