[0063] The straight clamping conveyor belt 32 is transmission-connected to a turning guide belt 33 at a position located at the high end of the conveyor frame 31 .

[0064] When the two straight clamping conveyor belts 32 clamp the green onions and convey them to the turning guide belt 33, the two turning guide belts 33 clamp the green onions and turn them to a nearly horizontal position along the fan-shaped direction of the turning guide belts 33. When the green onions fall from the turning guide belts 33 into the onion collecting device 7, they are placed neatly and not in a mess.

[0065] In this embodiment, the turning guide belt 33 and the straight clamping conveyor belt 32 are driven by sprockets and chains, and then, when the straight clamping conveyor belt 32 moves, the turning guide belt 33 is driven to move.

[0066] A cleaning group 34 is provided at the lower end of the conveying frame 31 and below the straight clamping conveyor belt 32 .

[0067] The cleaning group 34 includes a rotating shaft 341 rotatably connected to the conveying frame 31 , and the rotating shaft 341 is arranged along the length direction of the conveying frame 31 .

[0099] A guide wheel 505 is rotatably mounted at the end of the wheel frame 504 via a rotating shaft.

[0100] With such a design, when the guide mechanism 5 is in use, the power output end of the second hydraulic cylinder 53 extends or retracts to drive the rotating cover 54 to rotate up and down, thereby driving the guide wheel 505 to move up and down, and adjusting the up and down direction of the guide wheel 505.

[0101] The power output end of the hydraulic motor 59 rotates, driving the threaded rod 56 to rotate, driving the adjustment sleeve 58 to move left and right on the surface of the threaded rod 56 and the sliding shaft 57, thereby driving the guide wheel 505 to move left and right, adjusting the left and right direction of the guide wheel 505.

[0102] When the stroke of the threaded rod 56 and the sliding shaft 57 cannot meet the needs of the guide wheel 505, the left and right positions of the wheel frame 504 on the adjustment plate 502 are adjusted through the long waist hole 503, and then the left and right positions of the guide wheel 505 on the adjustment plate 502 are further adjusted to meet the needs.

[0108] A protective cover 45 is fixedly mounted on the upper surface of the mounting plate 41 at a position corresponding to the second corner transmission box 42 .

[0109] When the picking assembly 43 is in use, the power system drives the straight clamping conveyor belt 32 to move, and at the same time drives the straight clamping conveyor belt 32 to work, driving the sweeping brush 44 and the picking assembly 43 to rotate. At this time, the roots of the green onions dug from the ground by the excavating assembly 2 first pass through the sweeping brush 44 to remove the loose soil.

[0110] When the green onions to be dug are lying down, the picking assembly 43 first straightens the lying green onions, and then the digging assembly 2 performs digging.

[0111] When there are many dry yellow leaves on the green onions to be dug, the spiral sleeve 432 of the picking component 43 will entangle and remove the dry yellow leaves during the rotation process, perform preliminary processing on the green onions, and improve efficiency.

[0119] The outer surface of the connecting shaft 75 is vertically provided with an onion blocking plate 76. In this design, when the power output of the vertical push cylinder 73 extends, the connecting shaft 75 is driven to rotate, so that the onion blocking plate 76 is parallel to the onion connecting plate 72, and can block the onions falling from the onion connecting plate 72.

[0120] When the onion collecting device 7 is in use, the initial position is to control the output of the power output end of the horizontal push cylinder 71, that is, the onion receiving plate 72 is located just below the exit end of the turning guide belt 33, and is used to receive onions. After receiving a certain amount of onions, the power output end of the horizontal push cylinder 71 is controlled to retract, and the power output end of the vertical push cylinder 73 is extended, so that the onion blocking plate 76 is parallel to the onion receiving plate 72, blocking the onions falling from the onion receiving plate 72.

[0121] Then the horizontal push cylinder 71 and the vertical push cylinder 73 are operated alternately again, that is, the onion receiving plate 72 is driven to extend to continue receiving onions. At this time, the onion blocking plate 76 rotates, and the onions on the onion blocking plate 76 are put down in piles on the ground, and the onion placement is completed.

[0122] The power system is electrically connected to the control system 6 via electric wires.

[0123] The control system 6 includes other electrical components such as a radiator for driving and controlling the operation of the harvester. The specific installation and connection methods of the electrical components are well known in the prior art and will not be repeated here.

[0124] The temperature control switch 61 is electrically connected to the control system 6 via a wire.

[0125] The control system 6 is also provided with a circuit breaker 62 , and the circuit breaker 62 is electrically connected to the control system 6 through electric wires.

[0126] When the harvester is working, the power system will emit heat, causing the cab room to be too high, affecting the operator's work. The temperature control switch 61 can detect the temperature in the cab. When the temperature reaches the upper limit, the signal is fed back to the control system 6. The control system 6 drives the radiator to turn on to cool the power system. When the temperature is lower than the upper limit, the temperature control switch 61 feeds back a signal to the control system 6 to control the radiator to turn off, which can save resources.

[0127] When any part of the excavating assembly 2, the picking device 4 or the conveying device 3 encounters an obstacle during operation, causing the power system to overload, the circuit breaker 62 operates to shut down the power system through the control system 6 to avoid damage to the power system.

[0128] The working process of the green onion combine harvester is as follows: through the hydraulic system, the power output end of the second hydraulic cylinder 53 is driven to retract, the rotating cover 54 drives the guide wheel 505 to be lifted, the green onion combine harvester is driven to the green onion field, the power output end of the second hydraulic cylinder 53 is driven to extend, and the guide wheel 505 is driven to fall and contact the ground. According to the division status of the green onion field, the hydraulic motor 59 is driven to rotate, and the threaded rod 56 is driven to rotate, thereby driving the guide wheel 505 to move left and right, and the position of the guide wheel 505 is adjusted.

[0129] Then, the picking device 4 straightens the fallen green onions or performs preliminary processing on the dry and yellow green onion leaves. The digging component 2 works to dig the green onions from the ground, removes the loose soil through the sweeping brush 44, and further processes the soil at the roots of the green onions through the vibrating screen component 25. The straight clamping conveyor belt 32 clamps the green onions for transportation. During this period, the debris cleaning tooth plate 340 rotates to further remove the soil at the roots of the green onions. When the green onions are transported to the turning guide belt 33, the green onions are smoothly transported to the turning guide belt 33 under the action of the onion receiving brush 348. After being guided by the turning guide belt 33, the green onions fall into the onion collecting device 7 and are piled on the ground, completing the onion collection.

[0130] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and deformations made to the implementation methods are still within the protection scope of the present invention.
