Onions are extremely abundant, and in my country, they are primarily eaten fresh. With the improvement of people's quality of life, the demand for onions is increasing. However, onion cleaning is essential. Therefore, the use of onion cleaning devices can reduce manual labor and improve labor productivity. Currently, onion cleaning devices mainly include brush-based cleaning devices, paddle-based cleaning devices, drum-based cleaning devices, and spiral-based cleaning devices.

[0003] Existing onion cleaning devices, such as publication number CN221355652U, are a cleaning device for onion production, including a cleaning box, a water storage tank is provided at the bottom end of the cleaning box, a baffle is vertically arranged at the middle position above the water storage tank in the cleaning box, a first cleaning device is provided at one side of the baffle in the cleaning box, a second cleaning device is provided at the other side of the baffle in the cleaning box, and a first vibration component and a second vibration component are respectively provided at both sides below the second cleaning device; the overall structure of the utility model is simple, and onions can be cleaned in two stages, and the onions can be vibrated in the second stage cleaning.

[0004] Onions are easily bumped and damaged during the transfer from the primary cleaning device to the secondary cleaning device, and residual water is easily generated at the damaged parts by washing with water, causing the onions to become moldy.

[0005] Therefore, it is necessary to provide a new onion processing cleaning device to reduce the damage during the onion cleaning process to avoid mold. Utility Model Content

[0006] The purpose of the utility model is to provide a cleaning device for onion processing, which can effectively clean onions and reduce the collision during the onion cleaning process.

[0008] One end of the secondary cleaning box is provided with a feed port, and the other end is provided with a discharge port. The bottom plate of the secondary cleaning box is inclined from the feed port to the discharge port. A rotating device is provided in the secondary cleaning box. A third spray assembly facing the rotating device is provided above the rotating device. A drying assembly is provided above the discharge port of the secondary cleaning box.

[0009] A buffer box is provided between the primary cleaning box discharge port and the secondary cleaning box feed port. A buffer plate is provided in the buffer box facing the primary cleaning box discharge port and the secondary cleaning box feed port. A sponge is provided on the surface of the buffer plate and a plurality of buffer springs are provided on the back of the buffer plate.

[0010] Preferably, the drying assembly includes a drying box and a fan, the drying box is provided with a plurality of air outlets blowing downward, and the fan is installed on the top of the drying box.

[0011] Preferably, the group of cleaning rollers is composed of two rollers moving toward each other, with a gap for onions to pass through being provided between the two rollers, and soft brushes evenly distributed on the surface of the cleaning rollers.

[0012] Preferably, the rotating device includes a motor, a transmission shaft, and a plurality of blades. The transmission shaft is vertically arranged, and the blades are evenly distributed along the circumference of the transmission shaft. The length of the blades is smaller than the width of the secondary cleaning box.

[0013] Preferably, the first spray assembly, the second spray assembly and the third spray assembly each include a water injection pipe and a spray head.

[0014] Preferably, the water filter baffle is inclined at an angle of 10-45°, and a drainage trough is provided at the bottom of the water filter baffle.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The device washes onions multiple times through two cleaning devices. The onions first enter from the hopper and are first cleaned on the surface by the cleaning roller in the first cleaning box. After the cleaning is completed, they slide downward through the inclined water filter partition. The water filter partition is provided with a rotating shaft, and the surface of the rotating shaft is provided with bristles. The rotating shaft and the bristles are used for secondary cleaning. The water filter partition is provided with a drainage groove to avoid secondary contamination. When the onions enter the secondary cleaning box, they are cleaned for the third time by the rotating device and the third spray assembly.

[0017] (2) Traditional devices often do not pay attention to collisions during the transfer process, which can easily cause collisions of onion skins. This device avoids direct collisions during the onion transfer process by adding a buffer tank between the first cleaning tank and the second cleaning tank.

[0018] (3) A drying component is provided at the outlet of the second cleaning box of the device, which can blow away water stains on the surface of the onions. BRIEF DESCRIPTION OF THE DRAWINGS
