[0006] Furthermore, the screen is tiltedly arranged in the screening box, and the discharge port is located on the lower side of the tilted screen.

[0007] Furthermore, a bracket is provided at the bottom of the screening box, and a spring is provided between the screening box and the bracket.

[0008] Furthermore, a vibration motor is provided at the bottom of the bracket.

[0009] Furthermore, a collecting box is provided at the bottom of the screening box.

[0010] Furthermore, the screen is detachably installed in the screening box.

[0011] Furthermore, the collecting box is detachably mounted on the bottom of the screening box.

[0012] Furthermore, the conveyor is a roller conveyor.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure and is easy to install. After the onions are harvested, they are collected and poured into a hopper, and the onions are transmitted to a conveyor through a feeding port. The conveyor transfers the onions to a screening box. Onions of different sizes are screened by the screening box and then flow out through corresponding discharge ports. No manual screening is required, and farmers can complete the screening and bagging of onions through the discharge port, thereby improving work efficiency and reducing manual labor. The number of screens can be set according to needs, thereby improving practicality. The inclined screens and the low-position discharge ports help the onions to slide and avoid sedimentation. During operation, the operator can accelerate the screening of onions by shaking the screening box. The setting of the vibration motor improves the degree of automation of the utility model. The collection box can collect the onion skins that fall off during the screening process. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0019] An onion grading and bagging device comprises a hopper 1, a material outlet 2 is provided on the hopper 1, a conveyor 3 is connected to one end of the hopper 1 provided with the material outlet 2, a screening box 4 is connected to the conveyor 3, a screen 10 is provided in the screening box, the screen 10 is provided with multiple layers, the mesh diameters of the multiple layers of the screen 10 decrease from the top layer to the bottom layer, and each layer of the screen 10 is provided with a corresponding discharge port 5. The utility model has a simple structure and is easy to install. After the onions are harvested, they are collected and poured into the hopper 1, and the onions are conveyed to the conveyor 3 through the material outlet 2. The conveyor 3 transfers the onions to the screening box 4. Onions of different sizes are screened by the screening box 4 and then flow out through the corresponding discharge port 5. No manual screening is required. Farmers can complete the screening and bagging of onions through the discharge port 5, thereby improving the work efficiency and reducing the manual labor.

[0020] The screen 10 is tilted in the screening box 4, and the discharge port 5 is located on the lower side of the tilted screen 10. The tilted screen 10 and the low-positioned discharge port 5 help the onions to slide and avoid sedimentation.
