[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 7As shown, an embodiment of the utility model provides a large-angle auxiliary lifting device, including a base 1, a driving assembly and a conveying chain 2, wherein the conveying chain 2 is rotatably arranged on the base 1, and the base 1 is also provided with a driving assembly for driving the conveying chain 2 to rotate, and is characterized in that it also includes a baffle 3, and a plurality of baffles 3 are evenly arranged on the conveying chain 2 along its circumferential direction, and each of the baffles 3 is evenly provided with a plurality of notches 4.

[0029] Specifically, the base 1 is a supporting structure for installing the driving assembly and the conveying chain 2. The base 1 is tilted. A driven roller 7 is rotatably installed at the top and bottom of the base 1. Two transmission gears 8 are symmetrically installed at both ends of the two driven rollers 7. The two transmission gears 8 located on the same side of the two driven rollers 7 are each connected by a conveying chain 2; the driving assembly includes a driving chain 10 and a driving gear 9. A driving gear 9 is installed at the end of the driven roller 7 at the top of the base 1, and the driving chain 10 is connected to the driving gear 9; a driving member is rotatably installed at the bottom end of the base 1. When it is necessary to adjust the angle between the base 1 and the ground, the base 1 is driven to rotate by the driving member, so that the base 1 rotates to the conveying chain 2 to The angle required for the baffle 3 to transport potatoes provides convenience for the baffle 3 and the conveyor chain 2 to lift the potatoes. Each baffle 3 is a straight plate. A plurality of notches 4 are evenly provided on the end of each baffle 3 away from the conveyor chain 2. The notches 4 are used to discharge the soil blocks on the potatoes onto the conveyor chain 2. When it is necessary to lift the potatoes, the active chain 10 drives the active gear 9 to rotate, the active gear 9 drives the driven roller 7 to rotate, and the driven roller 7 drives the transmission gear 8 to rotate. Since the transmission gears 8 are connected and transmitted through the transmission chain, the transmission gear 8 drives the transmission chain to rotate, and the transmission chain drives the baffle 3 to rotate, so that the baffle 3 and the transmission chain can lift the potatoes. When there are some clods of soil attached to the potatoes, the clods of soil fall back to the ground from the notches 4 on the baffle 3, and when the conveyor chain 2 drives the baffle 3 to move, the baffle 3 shakes to a certain extent, so that the clods of soil attached to the potatoes fall from the notches 4 to the bottom surface under the shaking of the baffle 3, and the clods of soil and the potatoes can be separated to a certain extent, without the need for manual subsequent separation of the potatoes and the clods of soil, thereby reducing the labor intensity of the staff; in the prior art, most of the lifting devices transport the potatoes through a conveyor belt, and since there are many clods of soil on the potatoes, the potatoes and the clods of soil follow the lifting device into the collection box together, and the potatoes and the clods of soil cannot be separated, and manual subsequent separation of the potatoes is required. The separation of potatoes and soil increases the labor intensity of the staff; in the present embodiment, when it is necessary to transport potatoes from the bottom end to the collecting box, the conveyor chain 2 is driven to rotate by the driving assembly, and the conveyor chain 2 drives the baffle 3 to move, so that the baffle 3 and the conveyor chain 2 transport the potatoes to the collecting box. Since the baffle 3 is provided with a notch 4, the soil on the potatoes falls from the baffle 3 from the notch 4 to the ground, and the conveyor chain 2 and the baffle 3 shake to a certain extent when transporting the potatoes, so that the potatoes can shake to a certain extent, so that the soil on the potatoes can be discharged from the conveyor chain 2 and the baffle 3 from the notch 4 on the baffle 3, and there is no need for manual subsequent separation of potatoes and soil.

[0030] In another embodiment provided by the utility model, each of the baffles 3 is rotatably mounted with a U-shaped swing plate 5 at the top; the middle of each of the U-shaped swing plates 5 is rotatably mounted on the top of the corresponding baffle 3; two swing grooves 6 are symmetrically provided on the two side walls of the base 1; two sliding round rods 11 are symmetrically mounted at the ends of each of the U-shaped swing plates 5, and each of the sliding round rods 11 is slidably mounted in the corresponding swing groove 6; the bottom end of the swing groove 6 is aligned with the linear direction of the conveyor chain 2 and the linear direction of the base 1 The first oblique line segments 61 are parallel to each other, and the two ends of the first oblique line segment 61 are semicircular grooves 62, and the center of the semicircular grooves 62 at the two ends of the first oblique line segment 61 coincides with the center of the driven roller 7, and the top of the swinging groove 6 is the second oblique line segment 63 parallel to the linear direction of the conveyor chain 2 and the linear direction of the base 1, and the distance between the second oblique line segment 63 and the conveyor chain 2 is greater than the distance between the first oblique line segment 61 and the conveyor chain 2, and the second oblique line segment 63 and the two semicircular grooves 62 are connected by a third oblique line segment 64.

[0031] Specifically, the first oblique line segment 61 and the second oblique line segment 63 are parallel to the oblique direction of the base 1. When the transmission chain drives the baffle 3 to rotate, the baffle 3 drives the U-shaped swing plate 5 to move. During the process in which the baffle 3 drives the U-shaped swing plate 5 to move along the trajectory of the transmission chain: (1) when the U-shaped swing plate 5 drives the sliding round rod 11 to slide along the trajectory of the first oblique line segment 61 and the semicircular groove 62 of the swing groove 6, during the process in which the sliding round rod 11 slides in the first oblique line segment 61 and the semicircular groove 62, since the middle part of the U-shaped swing plate 5 is rotatably mounted on the top of the baffle 3, the bottom end of the U-shaped swing plate 5 is slidably mounted in the first oblique line segment 61 through the sliding round rod 11, so that the U-shaped swing plate 5 and the baffle 3 The U-shaped swing plate 5 is parallel to each other, that is, at this time, the baffle plate 3 and the U-shaped swing plate 5 are connected to each other to form a flat plate; (2) when the U-shaped swing plate 5 drives the sliding round rod 11 to slide along the semicircular groove 62 of the swing groove 6 into the third oblique line segment 64, since the distance between the second oblique line segment 63 and the conveying chain 2 is greater than the distance between the first oblique line segment 61 and the conveying chain 2, the third oblique line segment 64 connects the second oblique line segment 63 and the semicircular groove 62. When the sliding round rod 11 slides into the third oblique line segment 64, the sliding round rod 11 is pushed by the third oblique line segment 64, and since the middle part of the U-shaped swing plate 5 is rotatably installed on the top of the baffle plate 3, the sliding round rod 11 is squeezed by the third oblique line segment 64, so that the U-shaped swing plate 5 The plate 5 rotates at the position where it is rotatably connected to the top of the baffle plate 3, so that the U-shaped swing plate 5 rotates to a position perpendicular to the baffle plate 3, so that the U-shaped swing plate 5, the baffle plate 3 and the transmission chain are combined into a U-shaped structure. At the same time, the U-shaped swing plate 5 supports and digs the potatoes to a certain extent, and can dig the potatoes into the U-shaped structure, so that the U-shaped structure can stably lift the potatoes, and can effectively prevent the potatoes from falling from the baffle plate 3 to the ground, providing a stable transportation environment for the potato supply operation; (3) When the U-shaped swing plate 5 drives the sliding round rod 11 to slide along the third oblique line segment 64 of the swing groove 6 into the second oblique line segment 63, the sliding round rod 11 is subjected to the second The U-shaped swing plate 5, the baffle plate 3 and the transmission chain are combined into a U-shaped structure by the extrusion of the oblique line segment 63 to stably lift the potatoes; (4) when the U-shaped swing plate 5 drives the sliding round rod 11 to slide along the second oblique line segment 63 of the swing groove 6 to the third oblique line segment 64, the sliding round rod 11 is no longer squeezed by the second oblique line segment 63, so that the U-shaped swing plate 5 rotates at the position of the top rotation connection of the baffle plate 3, so that the baffle plate 3 and the U-shaped swing plate 5 are connected to each other to form a flat plate, so that the subsequent baffle plate 3 and the U-shaped swing plate 5 can transport the potatoes; the potatoes can be stably transported and the baffle plate 3 can be prevented from falling when the potatoes are lifted.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
