Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0026] Embodiment 1: As Figures 1 to 5 shown, this embodiment proposes an adjustable bucket grain elevator, including a base 1, a servo motor 3 and a second transmission wheel 5. A side plate 2 is installed on one side of the base 1, a servo motor 3 is installed on the outer wall of the side plate 2, a first transmission wheel 4 and a second transmission wheel 5 are movably installed on the outer wall of the side plate 2 away from the servo motor 3, a belt 6 is installed on the outer walls of the first transmission wheel 4 and the second transmission wheel 5, a slider 7 is movably installed on the outer wall of the belt 6, an insertion rod 8 is installed on the side of the slider 7 away from the belt 6, vertical rods 10 are symmetrically arranged on the outer wall of the top of the base 1 with the second transmission wheel 5 as the axis, a limit frame 9 is movably installed on the outer wall of the vertical rod 10, the outer wall of the insertion rod 8 fits with the inner wall of the limit frame 9, a first conveying plate 11 is arranged on the left side of the belt 6, and a second conveying plate 12 is arranged on the right side of the belt 6.

[0027] In this embodiment, the insertion rod 8 is composed of several straight rods with the same spacing. Spacing rods are arranged at the ends of the first conveying plate 11 and the second conveying plate 12 close to the belt 6, and the spacing rods match the insertion rod 8. This structure can move the grain from the first conveying plate 11 to the second conveying plate 12 through the insertion rod 8.

[0028] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, when using this structure, the servo motor 3 works to drive the first transmission wheel 4 to rotate. Then, through the second transmission wheel 5, the belt 6 performs a transmission movement. The transmission movement of the belt 6 drives the slider 7 to move along the transmission trajectory of the belt 6. Through the limiting effect of the inner wall of the limiting frame 9 on the slider 7 and the limiting effect of the vertical rod 10 on the limiting frame 9, the slider 7 maintains a horizontal state when moving along with the transmission of the belt 6. And the limiting frame 9 always maintains an up-and-down reciprocating movement under the action of the slider 7 and always limits the slider 7. By using the reciprocating horizontal movement of the slider 7, the insertion rod 8 is kept in a balanced movement to the lower part of the first conveying plate 11. Then, by using the dislocation structure between the insertion rod 8 and the first conveying plate 11, the grain bag transmitted above the first conveying plate 11 is conveyed and lifted to above the second conveying plate 12. Then, by using the dislocation structure between the second conveying plate 12 and the insertion rod 8, the grain bag is placed above the second conveying plate 12 and conveyed away. Through this structure, the balance can be always maintained during the transportation of grain, and the grain bag is not likely to fall off.

[0029] Embodiment 2: A telescopic rod 14 is provided on one side of the base 1 away from the side plate 2. The top end of the telescopic rod 14 is provided with a top plate 15. The top end of the top plate 15 is welded to the bottom end of the second conveying plate 12. The bottom end of the second conveying plate 12 is symmetrically provided with mounting blocks 21 with the top plate 15 as the axis.

[0030] In this embodiment, outer telescopic frames 13 are symmetrically installed on the outer wall of the top end of the base 1 with the telescopic rod 14 as the axis. Inner telescopic blocks 17 are movably installed on the inner walls of the outer telescopic frames 13. An equipment bin 16 is provided at the top end of the outer telescopic frames 13.

[0031] In this embodiment, a gear 18 is movably installed on the inner wall of the equipment bin 16. A worm 19 is movably installed below the gear 18. One end of the worm 19 penetrates through the outer wall of the equipment bin 16 and is connected with a turning handle 20.

[0032] In this embodiment, tooth blocks are evenly provided at one end of the inner telescopic block 17. The tooth blocks are meshed with the gear 18.

[0033] In this embodiment, helical tooth blocks are evenly provided on the outer wall of the worm 19. The worm 19 is meshed and driven with the gear 18 through the helical tooth blocks. This structure can convert the horizontal power into vertical power.

[0034] In this embodiment, rotating shafts 22 are symmetrically installed at the top end of the inner telescopic block 17. The inner telescopic block 17 is movably installed on the inner wall of the mounting block 21 through the rotating shafts 22.

[0035] Specifically, such as Figure 1 、 Figure 4 and Figure 5As shown in the figure, when using this structure, by manually rotating the turning handle 20, the worm 19 is driven to rotate. The meshing transmission between the worm 19 and the gear 18 drives the gear 18 to rotate. Then, the gear 18 meshes with the tooth block arranged at the lower end of the inner telescopic block 17 to drive the inner telescopic block 17 to move upward. The telescopic rod 14 is used to keep the top plate 15 and the mounting block 21 always balanced to support the second conveying plate 12. By means of the movable connection between the inner telescopic block 17 and the mounting block 21, the inner telescopic block 17 can automatically find the balance point according to the center of gravity in cooperation with the top plate 15, so that the grain bag can be transported steadily. This structure can automatically adjust the height of the second conveying plate 12 according to the position of the high-place grain bag, which is convenient for the transportation of the grain bag.

[0036] Working principle: According to the transmission position of the grain bag, manually rotate the turning handle 20. The turning handle 20 drives the worm 19 to rotate horizontally. The meshing transmission between the worm 19 and the gear 18 makes the gear 18 rotate around the vertical axis. Then, the tooth block arranged at the lower end of the inner telescopic block 17 and meshing with the gear 18 is used to longitudinally drive the inner telescopic block 17, so that it moves upward along the inner wall of the outer telescopic frame 13. The telescopic rod 14 makes the top plate 15 and the mounting block 21 always keep a horizontal supporting effect on the second conveying plate 12. Place the grain bag above the first conveying plate 11, start the servo motor 3, the servo motor 3 drives the first transmission wheel 4 to rotate. The first transmission wheel 4 and the second transmission wheel 5 are used in cooperation to make the belt 6 perform a circulating transmission movement. The belt 6 drives the slider 7 to move along the same track. Then, the limiting frame 9 limits the slider 7 to keep it horizontal. Through the limiting of the vertical rod 10 on the limiting frame 9, the slider 7 drives the limiting frame 9 to move up and down and always keeps the limiting of the slider 7, so that the plugging rod 8 keeps balanced along with the movement track of the slider 7. When the plugging rod 8 moves to the lower part of the first conveying plate 11, according to the dislocation structure between the first conveying plate 11 and the plugging rod 8, the grain bag above the first conveying plate 11 is transferred to the surface of the plugging rod 8. When the plugging rod 8 moves above the second conveying plate 12, and then using the dislocation structure between the plugging rod 8 and the second conveying plate 12, the grain bag is transferred above the second conveying plate 12 for transmission. This structure can not only keep the transmission at high and low places balanced during grain lifting, avoid the grain bag from tilting and falling, and ensure stable transmission, but also adjust the height of the second conveying plate 12 according to the transmission position of the high-place grain bag to make it horizontal with the transmission position, which is convenient for grain lifting.

[0037] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
