DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 5As shown collectively, an onion discharging device for an onion combine harvester comprises an onion discharging frame 1, on which an onion discharging plow 2 and a threshing harrow 3 are arranged at the front and rear, a reciprocating vibration mechanism 4 is installed between the threshing harrow 3 and the onion discharging frame 1, a supporting roller 5 is arranged on one side of the onion discharging plow 2, and the supporting roller 5 is installed on the onion discharging frame 1 through a two-way adjustment mechanism 6.

[0028] In this embodiment, the rear end of the onion output rack 1 is hingedly installed on the frame 7 of the green onion harvester, and a first hydraulic cylinder 71 is hingedly installed between the onion output rack 1 and the frame 7. A bracket 8 is fixed on the conveying frame of the conveying device of the green onion harvester, and a pair of second hydraulic cylinders 81 are hingedly installed between the bracket 8 and the onion output rack 1.

[0029] In this embodiment, the first hydraulic cylinder 71 and the second hydraulic cylinder 81 are used to lift and lower the onion output rack 1 .

[0030] like Figure 2 and Figure 3 As shown together, the beating rake 3 includes a first beating rod 31 and a second beating rod 32 which are perpendicular to each other. The rear end of the first beating rod 31 is hingedly mounted on the onion output rack 1, and the second beating rod 32 is fixedly mounted on the front end of the first beating rod 31. Both ends of the second beating rod 32 and the onion output rack 1 are hingedly connected with a first fine-tuning screw rod 33, and third beating rods 34 are fixedly mounted between both ends of the second beating rod 32 and the first beating rod 31 respectively. A plurality of beating teeth 35 are fixed on the first beating rod 31, the second beating rod 32 and the third beating rod 34.

[0031] In this embodiment, a triangular-shaped soil-beating rake 3 is used, and the soil-beating teeth 35 are used to thoroughly clean the soil on the roots of the green onions.

[0032] Compared with the grid-shaped screen in the existing green onion harvester, the roots of the soil-beating teeth 35 in this embodiment are not easily entangled on the soil-beating teeth 35 during the reciprocating cleaning process, thereby reducing the occurrence of green onion being pulled off due to the entanglement of the roots.

[0033] Among them, the reciprocating vibration mechanism 4 includes a first hydraulic motor 41 fixedly installed on the onion output rack 1, a rotating wheel 42 is fixedly installed on the output shaft of the first hydraulic motor 41, an eccentric column 43 is fixed on the end face of the rotating wheel 42, and a second fine-tuning screw 44 is hinged between the eccentric column 43 and the first soil-beating rod 31.

[0034] like Figure 1 and Figure 4 As shown together, the two-way adjustment mechanism 6 includes a fixed frame 61 fixedly mounted on the onion output rack 1, a sliding frame 62 is slidably mounted on the fixed frame 61 along the horizontal direction, the sliding frame 62 is driven to slide by a transverse driving assembly 63, and the supporting wheel 5 is installed on the sliding frame 62 through a height adjustment assembly 64.

[0035] Moreover, the transverse drive assembly 63 includes a horizontally arranged adjusting screw 631, which is arranged along the sliding direction of the sliding frame 62. Both ends of the adjusting screw 631 are rotatably installed on the fixed frame 61. A sliding seat 632 is installed on the adjusting screw 631 in a threaded manner. The sliding frame 62 is fixedly installed on the sliding seat 632. One end of the adjusting screw 631 is transmission-connected to a second hydraulic motor 633.

[0036] In this embodiment, the transverse driving assembly 63 is used to control the horizontal position adjustment of the supporting wheel 5, so that the position of the supporting wheel 5 can be freely adjusted according to the actual ridge distance and width of the planting site.

[0037] Therefore, the situation that the supporting wheels 5 are pressed onto the field ridges or green onions due to the unadjustable horizontal position is avoided, thereby improving the applicability of the utility model and making the utility model suitable for the green onion harvesting work with different ridge distances and ridge widths.

[0038] The height adjustment assembly 64 includes a support arm 641 and a lifting cylinder 642. The supporting wheel 5 is rotatably mounted on the front end of the support arm 641. The rear end of the support arm 641 is hingedly mounted on the side wall of the lower end of the sliding frame 62. The upper end of the lifting cylinder 642 is hingedly mounted on the side wall of the upper end of the sliding frame 62. The lower end of the lifting cylinder 642 is hingedly mounted on the support arm 641.

[0039] In this embodiment, the height adjustment component 64 is provided to control the height adjustment of the supporting wheel 5. The grower can freely adjust the height of the supporting wheel 5 according to factors such as the planting depth of the green onions, the actual situation of the land, and the harvesting requirements.

[0040] Thereby, it is ensured that the onion discharging plow 2 always performs onion discharging work at a predetermined depth, which not only ensures the complete harvest of the green onions, but also improves the adaptability of the onion discharging device.

[0041] In addition, two guide light rods 65 are installed on the fixed frame 61 , each of the guide light rods 65 is parallel to the adjusting screw 631 , and each of the guide light rods 65 is slidably installed with a sliding sleeve 66 , and each of the sliding sleeves 66 is fixed on the sliding frame 62 .

[0042] The process of using the onion discharging device to discharging green onions is as follows:

[0043] In the first step, the green onion harvester moves to the green onions to be harvested, aligns the onion plow 2 with the green onion planting ridges, and controls the onion rack 1 to fall through the first hydraulic cylinder 71 and the second hydraulic cylinder 81, and inserts the onion plow 2 into the ridges to reach a predetermined onion harvesting depth.

[0044] In the second step, the second hydraulic motor 633 is started, driving the adjusting screw 631 to rotate, so that the slide 632 moves horizontally on the adjusting screw 631, and the horizontal position of the supporting roller 5 is adjusted. After the supporting roller 5 is adjusted to the appropriate position, the second hydraulic motor 633 is controlled to start.

[0045] The third step is to control the piston rod of the lifting cylinder 642 to extend outward to a suitable length, drive the supporting wheel 5 to fall to the ground, and limit the depth of the onion plow 2 into the soil.

[0046] In the third step, the first hydraulic motor 41 is started, and the first hydraulic motor 41 drives the rotating wheel 42 to rotate in height, and the second fine-tuning screw rod 44 eccentrically hingedly installed on the rotating wheel 42 reciprocates, thereby driving the soil harrow 3 to reciprocate and swing at high speed in the horizontal direction.

[0047] In the fourth step, the green onion harvester continues to move forward, and uses the onion plow 2 inserted into the field ridge to dig out the green onions. Under the action of the conveying device of the green onion harvester, the green onions are driven to be gradually raised while being conveyed backward, so that the roots of the green onions are separated from the ground.

[0048] In the fifth step, a large amount of soil is still attached to the roots of the green onion transported to the soil-beating rake 3, and the soil-beating rake 3 uses the soil-beating teeth 35 that are constantly in action to knock the soil attached to the roots off.

[0049] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
