Detailed ways

In the embodiment shown in Fig. 1, the suspension frame (2) is first docked with the hydraulic suspension system of the tractor. When the tractor travels to the job site, the driver operates the handle of the hydraulic distributor of the tractor, puts the implement on the ground, and installs it on the ground. The pick-up shovel (1) at the front of the overall frame (3) touches the ground, starts the tractor in the first gear, and pulls the implement forward with the tractor suspension. The pick-up shovel (1) shovels the onions on the ridge together with some soil particles into the machine Inside, enter the onion conveying device (4), in the process of conveying the onion by the onion conveying device, the soil particles wrapped together with the onion will fall into the ground at the gap of the grid bar (11) of the onion conveying device (4), assisting the push The rotation of the device (5) quickly pushes the onions transported on the auxiliary onion conveying device (4) to the onion cutting device (6) to prevent the onion from being blocked at the handover position of the pick-up shovel (1) and the onion conveying device (6). The phenomenon affects the normal running of the machine. The onion enters the onion cutting device (6) to complete the work of cutting the onion. The onion is turned, and the residual onion is brought into contact with the cutting screw rod (29) and the smooth cutting rod (30) in the onion cutting device (6) to complete the cutting work, and at the same time, the onion is smoothly delivered to the conveying device (6). 8) Location, and then transported to the agricultural transport vehicle for delivery to the destination.
