[0037] like Figures 1 to 7 As shown, according to a first aspect of the present invention, a guide structure for a crop lifting device is provided, the guide structure for the crop lifting device including a guide mounting plate 4 and a guide block 5.

[0038] In the following description, reference will be made to Figures 1 to 7 The specific structure of the aforementioned components of the guiding structure used in the rice-lifting device and the connection relationship of the aforementioned components are described in detail.

[0039] like Figures 1 to 7 As shown, in this embodiment, the roller 2 can be located at the end of the supporting base plate 1. The chain 3 can be routed around the roller 2. Multiple supporting fingers 10 can be mounted on the chain 3, which drives the supporting fingers 10 to move from the lower part of the supporting base plate 1, around the roller 2, to the upper part of the supporting base plate 1. A guide plate 4 can be mounted at the end of the supporting base plate 1. A support surface can be provided on the top of the guide plate 4 to support and buffer the supporting fingers 10. A guide block 5 can be mounted on the guide plate 4. When the supporting fingers 10 move close to the roller 2, the guide block 5 abuts against the supporting fingers 10. At this time, the guide block 5 can guide the movement, reducing the impact and noise generated by the supporting fingers 10 during movement.

[0040] Preferred, such as Figure 1 As shown, in this embodiment, the supporting base plate 1 can be formed into a long strip shape. The chain 3 can drive the supporting finger 10 to move clockwise along the supporting base plate 1 (e.g., Figure 1 The direction of movement is shown in 8). Multiple lifting fingers 10 can be installed at intervals on the chain 3. The lifting fingers 10 can be pivotally connected to the chain 3, so that the lifting fingers 10 can be in a retracted state when moving under the lifting base plate 1 (i.e., as shown in 8). Figure 1 As shown, the lifting finger 10 is close to the chain 3, and after passing the roller 2 and the guide block 5, the lifting finger 10 can be in an upright state.

[0041] Preferred, such as Figures 1 to 4 As shown, in this embodiment, the guide block 5 can be positioned close to the roller 2. An inclined guide surface 51 extending towards the bottom end of the roller 2 can be formed on the lower side of the guide block 5 (i.e., the lower side in the normal installation state). This allows the lifting finger 10 to first contact the guide block 5 when it moves close to the roller 2. As the lifting finger 10 passes the guide block 5, its bottom abuts against the inclined guide surface 51 of the guide block 5, enabling the lifting finger 10 to move along the inclined guide surface 51. Under the reaction force of the inclined guide surface 51 on the lifting finger 10, the lifting finger 10 can rotate around its hinge point with the chain 3, gradually increasing the angle between the lifting finger 10 and the chain 3, thus gradually changing its posture to reduce impact and noise during movement.

[0042] Furthermore, preferably, such as Figures 1 to 4As shown, in this embodiment, a straight guide surface 52 can be formed at the bottom end of the guide block 5, which can connect with the inclined guide surface 51. Specifically, the end of the straight guide surface 52 can smoothly transition to the bottom end of the inclined guide surface 51, so as to facilitate the movement of the lifting finger 10 from the inclined guide surface 51 to the straight guide surface 52. After the lifting finger 10 passes the inclined guide surface 51, the bottom of the lifting finger 10 abuts against the straight guide surface 52 and moves along the straight guide surface 52 to the roller 2.

[0043] Preferred, such as Figure 1 , Figures 4 to 7 As shown, in this embodiment, the guide mounting plate 4 may include a vertical plate portion 41 and a horizontal plate portion 42. The vertical plate portion 41 can be mounted to the load-bearing base plate 1 using fixing bolts 500, and the guide block 5 can be mounted on the vertical plate portion 41. The horizontal plate portion 42 can be located at the top of the vertical plate portion 41, and the supporting surface can be the top surface of the horizontal plate portion 42. After the load-bearing finger 10 passes the roller 2, the load-bearing finger 10 first contacts the horizontal plate portion 42, and the bottom of the load-bearing finger 10 can move along the top surface of the horizontal plate portion 42. An inclined guide section 420 can also be provided at one end of the horizontal plate portion 42 near the roller 2 to facilitate the movement of the load-bearing finger 10 to the top surface of the horizontal plate portion 42 and to guide the movement of the load-bearing finger 10. After the load-bearing finger 10 passes the guide section 420, the load-bearing finger 10 is in a fully upright state.

[0044] Further optimized, such as Figures 4 to 7 As shown, in this embodiment, the vertical plate portion 41 of the guide mounting plate 4 may have a mounting hole 410. The guide block 5 may be provided with a mounting sleeve 50. The guide block 5 and the guide mounting plate 4 can be mounted to the bottom plate 1 using fixing bolts 500. Specifically, the fixing bolts 500 can pass through the mounting hole 410 and the mounting sleeve 50, thereby fixing the guide block 5 and the guide mounting plate 4.

[0045] Furthermore, preferably, such as Figure 4 and Figure 5 As shown, in this embodiment, there are multiple mounting holes 410, which can be spaced apart to increase the mounting strength of the guide mounting plate 4. Correspondingly, the number of mounting sleeves 50 of the guide block 5 can be equal to the number of mounting holes 410, and the multiple mounting sleeves 50 can be arranged one-to-one with the multiple mounting holes 410.

[0046] Furthermore, preferably, in this embodiment, the guide mounting plate 4 and the mounting sleeve 50 can be made of metal to ensure their structural strength. The guide block 5 can be made of polyurethane to improve the wear resistance of the guide block 5 and reduce the wear of the lifting finger 10, as well as reduce the noise generated when the guide block 5 and the lifting finger 10 are in contact.

[0047] Preferred, such as Figure 1 As shown, in this embodiment, the guiding structure for the lifting device may further include a fixed guide rail 6. The fixed guide rail 6 can be bolted to the lifting base plate 1. The end of the fixed guide rail 6 can be connected to the transverse plate portion 42 of the guide mounting plate 4, so that the lifting finger 10 can reach the top of the fixed guide rail 6 after moving along the transverse plate portion 42, thereby further guiding the movement direction of the lifting finger 10.

[0048] Furthermore, preferably, such as Figure 1 As shown in the embodiment, the guiding structure of the lifting device may further include a sliding guide rail 7. The sliding guide rail 7 is movably mounted on the lifting base plate 1. After the movable guide rail moves to the desired position, the position of the sliding guide rail 7 can be fixed by bolts. The sliding guide rail 7 can be connected to the fixed guide rail 6, so that the lifting finger 10 can reach the top of the sliding guide rail 7 after moving along the fixed guide rail 6. The operator can adjust the movement stroke of the lifting finger 10 by adjusting the position of the sliding guide rail 7.

[0049] Furthermore, according to a second aspect of this utility model, a rice-lifting device is provided, comprising a rice-lifting base plate 1, rollers 2, and a chain 3, as described above, a guiding structure for rice-lifting devices. The rollers 2 can be disposed at the end of the rice-lifting base plate 1. The chain 3 is disposed around the rollers 2, and a plurality of rice-lifting fingers 10 are mounted on the chain 3. The chain 3 drives the rice-lifting fingers 10 to move, and the guiding structure for rice-lifting devices can be installed at the end of the rice-lifting base plate 1 for guiding the rice-lifting fingers 10 during their movement.

[0050] During use, the guiding structure of the lifting finger 10 in the lifting device guides the movement of the lifting finger 10, reducing the impact on the lifting finger 10 during movement, thereby extending the life of the lifting finger 10 and reducing the noise during operation. In addition, the guide block 5 uses polyurethane material, which can further reduce the wear of the lifting finger 10, extend the life of the lifting finger 10, and achieve the effect of shock absorption and noise reduction.

[0051] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application.
