Detailed ways

In order to make the purpose and technical solutions of the embodiments of the present invention more clear, the following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

The present invention proposes a leek harvester, as shown in FIG.

Wind force seedling pulling mechanism is positioned at the front end of frame 1, and as shown in Figure 2, wind force seedling pulling mechanism comprises air supply pipe 5, air collection pipe 6 and seedling pulling device 7. There are two air supply pipes 5, which are respectively located on the left and right sides of the front end of the frame 1, and the two air supply pipes 5 are connected to the air outlet of the blower 4. The front end of each air-supply pipe 5 is connected with an air-collecting pipe 6, and the right side wall of the air-collecting pipe 6 positioned at the left-hand side air-supply pipe 5 is provided with some injection ports. Offer some injection openings on the left side wall of 6. The front end of each air supply pipe 5 is also provided with a seedling pulling device 7, and one end of the seedling pulling device 7 on the left side is fixed on the left side air supply pipe 5 outer wall, and the other end extends to the left rear, and the seedling pulling device on the right side One end of 7 is fixed on the right side air supply pipe 5 outer walls, and the other end extends to the right rear, and the seedling puller 7 is used to separate the leeks of different planting rows. During work, the wind blown out by the blower 4 enters into the left and right air supply pipes 5, and sprays out from the injection ports of the left and right air collecting pipes 6, so as to gather together the leeks in the harvesting rows, and the seedling puller 7 will plant them differently. Rows of leeks separate for easy cutting.

The cutting mechanism is located in the middle of the wind force seedling pulling mechanism, and the cutting mechanism includes a motor, a gear box, two vertical rotating shafts arranged left and right and a cutting knife 8 positioned on the rotating shaft. The motor drives two rotating shafts to rotate vertically through the gear box, and a cutting knife 8 is fixed on each rotating shaft, and the rotation direction of the front ends of the two cutting knives 8 is towards the inside. As shown in FIG. 3 , the cutting knife 8 is composed of six blades 9 , and each blade 9 is provided with a retracting hook 10 along the direction of rotation. By arranging the two cutting knives 8, the harvesting efficiency is improved, and by setting the gathering hook 10 on the blade 9 of the cutting knives 8, it is convenient to collect the cut chives.

Collection box 3 is fixed on the frame 1, is used for collecting the leek after cutting. The upper end of the collection box 3 is provided with a first opening 11 and a second opening 12; the first opening 11 is connected to the air inlet of the blower 4; the second opening 12 is connected to one end of the conveying pipeline 2, and the other end of the conveying pipeline 2 is placed above the cutting mechanism . A vertical isolation deflector 13 is provided between the first opening 11 and the second opening 12 . The leek after cutting enters from the second opening 12 on the upper end of the collection box 3 through the delivery pipe 2 under the suction of the blower 4, and then falls to the bottom of the collection box 3. The isolation deflector 13 separates the first opening 11 and the second opening 12 to prevent leeks from being directly sucked from the second opening 12 to the first opening 11, and cannot fall and block the air inlet of the blower 4 . At the same time, the isolation deflector 13 plays a guiding role for the gas flow, so that the direction of the airflow at the second opening 12 is downward, and the leeks can fall quickly after entering the collection box 3 .

Two wheels 14 are arranged symmetrically on the left and right sides of the bottom of the frame 1 , and the two wheels 14 are connected by a drive shaft 15 .

The leek harvester of the present invention also includes a fertilization mechanism positioned on the frame. As shown in FIG. The fertilizer bucket 16 is placed on the frame 1. The horizontal transmission cylinder 17 is positioned at the bottom of the chemical fertilizer bucket 16 and is fixed on the driving shaft 15. The top of the horizontal transmission cylinder 17 is provided with a fertilizer inlet 19, and the horizontal transmission cylinder 17 communicates with the chemical fertilizer bucket 16 through the fertilizer inlet 19. The horizontal transmission cylinder 17 A horizontal conveying screw 18 fixed on the driving shaft 15 is provided inside, and a fertilizer outlet 20 is provided at the side end of the horizontal conveying cylinder 17 . During work, drive shaft 15 is rotated by wheel 14, and the chemical fertilizer in the chemical fertilizer bucket 16 enters in the horizontal transfer cylinder 17 through chemical fertilizer inlet 19, is conveyed toward chemical fertilizer outlet 20 direction by conveying screw rod 18, flows out from chemical fertilizer outlet 20. Fertilizing leeks while harvesting leeks is conducive to the regrowth of leeks.

Preferably, the bottom of the vehicle frame 1 is provided with a turning wheel, and the turning wheel renovates the soil, which is beneficial to soil fertilization.

The working process of the leek harvester is as follows: when working, the wind blown by the blower 4 enters the two left and right air supply pipes 5, and is sprayed out from the injection ports of the left and right two air collection pipes 6, so as to gather the leeks in the harvested rows together, The seedling puller 7 separates the leeks in different planting rows for easy cutting; the motor drives two cutting knives 8 to rotate through the gear box, and the cutting knives 8 cut the leeks; At the same time, the wheels 14 drive the drive shaft 15 to rotate, and the fertilizer in the fertilizer bucket 16 enters the horizontal transmission cylinder 17 through the fertilizer inlet 19, and is transported by the conveying screw 18 to the fertilizer outlet 20, and then the fertilizer is transported from the fertilizer outlet 20 outflow to fertilize the soil.

The above is only the embodiment of the present invention, and its description is relatively specific and detailed, but it should not be construed as limiting the patent scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
