Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading racks, in particular to a grape loading and unloading rack. Background Technique

[0002] After grapes are picked, they are generally placed in fruit baskets for storage, and then the fruit baskets filled with grapes are stacked on a freight car for transportation. When the freight car arrives at the grape storage warehouse, it is necessary to unload the fruit baskets filled with grapes from the freight car. The traditional method is that one worker stands on the freight car to pick up the fruit basket, and another worker stands under the freight car to pick up the fruit basket by hand. This method of unloading fruit baskets has low efficiency and requires a large amount of manpower. Sometimes, because the hand is separated from the fruit basket, the grapes inside the fruit basket are likely to spill.

[0003] In order to improve the unloading efficiency of the fruit basket, although some fruit merchants use an inclined conveyor loading and unloading rack or a neatly arranged conveyor roller loading and unloading rack to convey the fruit basket during the unloading process of the fruit basket, the inclination angles of most loading and unloading racks are not easy to adjust within a large range to adapt to freight car boxes of different heights, and the use limitations are relatively large. In addition, some loading and unloading racks use cylinders as the power support equipment for supporting the inclination of the loading and unloading rack. However, when the loading and unloading rack is not in use, the cylinder and the loading and unloading rack cannot be completely flattened and stored, resulting in the loading and unloading rack that is not in use occupying a large space. Content of the Utility Model

[0004] The purpose of the utility model is to provide a grape loading and unloading rack to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A grape loading and unloading rack includes a bearing rack. The bearing rack includes two symmetrically distributed top rods. A conveying component is rotatably connected between one ends of the two top rods. The conveying component includes a rotating shaft rotatably connected to the top rods. Shaft rods are fixed at both ends of the rotating shaft. A plurality of rollers are rotatably connected at equal intervals between the two shaft rods. A regulating component is arranged at the bottom of the conveying component. The regulating component includes a positioning shaft. Transmission rod one and transmission rod two are rotatably connected at both ends of the positioning shaft. The top end of the transmission rod one is rotatably connected to the shaft rod. The bottom end of the transmission rod two is rotatably connected to the bearing rack. A driving shaft is fixed between the two transmission rod twos. A U-shaped rod is fixed inside the bearing rack. A cylinder is rotatably connected between the U-shaped rod and the driving shaft. A hand-operated air source component for supplying air to the cylinder is fixed at the bottom of the bearing rack.

[0007] Furthermore: A sleeve rotatably connected to the rotating shaft is fixed at one end of the top rod. A cross bar one is fixed between one ends of the two top rods.

[0008] Furthermore, one end of the ejector rod背离横杆一的一端以及横杆一的两端均固定有支撑杆,所述支撑杆的底面安装固定有万向脚轮。

[0010] Furthermore, a plurality of connecting seats respectively rotatably connected to the corresponding rollers are fixed on the outer side of the shaft rod, a connecting rod two is fixed between one ends of the two shaft rods, and a stop rod is fixed on the top of the shaft rod.

[0011] Furthermore, two columns are fixed to the bottom of the cross bar one, a traction shaft one fixedly connected to the shaft rod is rotatably connected between one ends of the two transmission rods one, and a traction shaft two fixedly connected to the column is rotatably connected between one ends of the two transmission rods two.

[0012] Furthermore, the C-shaped rod is rotatably connected to the bottom end of the air cylinder, two diagonal braces two are fixed to the outer side of the C-shaped rod, and a connecting rod three fixedly connected to the bearing frame is fixed between the bottom ends of the two diagonal braces two.

[0013] Furthermore, the hand-operated air source assembly includes a control box fixedly connected to the bearing frame, and a crank is rotatably connected to the outer side of the control box.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. By extending the output end of the air cylinder to push the drive shaft obliquely upward, the drive shaft pushes the transmission rod two obliquely upward, so that the included angle between the transmission rod one and the transmission rod two becomes larger, thereby enabling the two transmission rods one to push the shaft rod on the drive assembly upward, and further enabling the two shaft rods to rotate around the sleeve as the axis, realizing the adjustment of the inclination angles of the two shaft rods and the multiple rollers between the two shaft rods. The shaft rod can drive the roller to be placed obliquely at different heights of the freight car carriage, and the fruit basket filled with grapes is released along the multiple obliquely arranged rollers, and the fruit basket can be automatically conveyed and unloaded along the rollers, which is beneficial to improving the loading and unloading efficiency of the grape fruit basket from the freight car and expanding the use range of the loading and unloading rack of the present application.

[0016] 2. By shortening the output end of the cylinder, the output end of the cylinder drives the drive shaft to move obliquely downward, the included angle between the first transmission rod and the second transmission rod becomes smaller, and finally the first transmission rod and the second transmission rod are received inside the carrier, and the conveying component is placed flat on the carrier. By arranging the cylinder obliquely and cooperating with the first and second transmission rods arranged in a V-shaped rotation, it is convenient to adjust the inclination angle of the conveying component within the maximum range, and at the same time, the loading and unloading rack and the cylinder can be received, reducing the space occupied by the loading and unloading rack.
