DETAILED DESCRIPTION

[0028] 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 in 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.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1-Figure 5 The utility model provides a leek harvester, comprising:

[0031] The machine body is composed of a bottom plate 1, a pair of first mounting plates 2 fixedly connected to the front end of the bottom plate 1, a pair of second mounting plates 3 fixedly connected to the middle of the bottom plate 1, a pair of push rods 4 fixedly connected to the rear end of the bottom plate 1, and a plurality of universal wheels 5 fixedly connected to the bottom surface of the bottom plate 1;

[0032] A first motor 6 is fixedly mounted on any first mounting plate 2, and an output shaft of the first motor 6 is coupled to a crop supporter 7 located between a pair of second mounting plates 3, and a plurality of comb teeth 71 are provided on the crop supporter 7;

[0033] The second motor 8 is fixedly mounted on the bottom surface of the base plate 1. The output shaft of the second motor 8 is matched with a threaded rod 9 through a gear assembly. A cutter 10 is slidably matched on the threaded rod 9. The cutter 10 is located below the crop supporter 7. A pair of nuts 11 are threadedly matched on the threaded rod 9. The cutter 10 is located between the pair of nuts 11.

[0034] The third motor 12 is fixedly mounted on the top surface of the bottom plate 1. The output shaft of the third motor 12 is coupled with a conveyor belt 13 through a transmission assembly. The width of the conveyor belt 13 is the same as that of the rice supporter 7.

[0035] The collecting frame 14 is fixedly mounted on the top surface of the bottom plate 1 , and the conveyor belt 13 is located between the collecting frame 14 and the straw supporter 7 .

[0036] The first motor 6 drives the straw supporter 7, which causes the leeks to fall backwards, so that after being cut by the cutter 10, they can fall onto the conveyor belt 13 and be collected and transported to the collection frame 14, thereby achieving the effect of cutting and collecting. In the cutting process, the leek leaves can be gathered by a number of comb teeth 71 on the straw supporter 7 to facilitate cutting. At the same time, it is also to prevent the leek leaves from spreading after cutting, thereby improving the cutting quality of the leek.

[0037] The cutting knife is fixed on the threaded rod 9 by the nut 11. By adjusting the position of the nut 11 on the threaded rod 9, the height of the cutting knife 10 from the ground can be accurately adjusted to adapt to the cutting position of the second and third crops of leeks.

[0038] It should be noted that the harvesting height of leeks is 3-4 cm from the ground. Relevant data show that when harvesting leeks, subsequent harvests, including the second crop, are generally 1-2 cm higher than the previous crop. This is mainly to ensure that the leeks can heal quickly and grow normally after harvesting.

[0039] A further optimized solution of the rice support device 7 includes a cage-shaped shell 72, which is rotatably engaged between a pair of first mounting plates 2, and the cage-shaped shell 72 is driven by the output shaft of the first motor 6, and a plurality of comb teeth 71 are fixedly connected to the truss of the cage-shaped shell 72.

[0040] The comb teeth 71 are arranged on the cage-shaped shell 72 for easy production and manufacturing, and the cage-shaped shell 72 is preferably a hexagonal structure.

[0041] A further optimized gear assembly includes a limiter 15, which is fixedly connected to the bottom surface of the base plate 1, and the limiter 15 is rotatably matched with a first bevel gear 16 and a second bevel gear 17 that mesh with each other, and the first bevel gear 16 and the second bevel gear 17 are perpendicular to each other, the first bevel gear 16 is matched with the output shaft of the second motor 8, and the second bevel gear 17 is fixedly connected to the threaded rod 9.

[0042] The first bevel gear 16 and the second bevel gear 17 are supported by the limiter 15 to ensure smooth transmission. The first bevel gear 16 and the second bevel gear 17 realize the change of transmission direction and convert the horizontal rotation of the output shaft of the second motor 8 into vertical rotation.

[0043] Furthermore, the second motor 8 uses a lithium-ion lawn mower 775 motor with a rotation speed of 11000 r / min and a rated voltage of 21 V, and can be connected to a speed regulator for speed regulation.

[0044] In a further optimized solution, there are multiple cutting knives 10, and the multiple cutting knives 10 are arranged side by side.

[0045] A plurality of cutters 10 correspond to a plurality of rows of leeks, and the leeks are harvested simultaneously, so the harvesting efficiency is high.

[0046] The diameter of the cutter 10 is 15 cm, and the distance between the center lines of two adjacent cutters 10 is 26 cm. Therefore, multiple rows of leeks with a planting spacing within the range of 15-38 cm can be harvested, which is consistent with the planting spacing range of leeks.

[0047] A further optimized transmission assembly includes an active roller 18 and a driven roller 19, the conveyor belt 13 is driven and matched between the active roller 18 and the driven roller 19, the active roller 18 is rotatably matched between a pair of second mounting plates 3, the driven roller 19 is rotatably matched between a pair of first mounting plates 2, the active roller 18 is higher than the driven roller 19, so that the conveyor belt 13 is tilted, the inclination angle of the conveyor belt 13 is 20°, and the active roller 18 and the output shaft of the third motor 12 are driven and matched through a pair of sprockets 20 and a chain 21.

[0048] The power of the third motor 12 is transmitted to the active roller 18 through the chain drive of the sprocket 20 and the chain 21, driving the movement of the conveyor belt 13 to transport the leeks.

[0049] The conveyor belt 13 of the further optimized solution is a grass-grain climbing type with a thickness of 4 mm to enhance friction and ensure that the leeks can be smoothly collected into the collection frame 14.

[0050] In a further optimization scheme, a cover shell 22 is fixedly connected to the top surface of the bottom plate 1, and an infrared sensor (not shown in the figure) corresponding to the upper and lower parts of the collection frame 14 is fixedly installed on the top surface of the cover shell 22. The infrared sensor is connected to the single-chip microcomputer. When the leeks are fully collected, the sensor transmits data to the single-chip microcomputer, and the indicator light is controlled by the single-chip microcomputer to indicate that the leeks are fully collected.

[0051] In a further optimized solution, one end of the cover 22 close to the push rod 4 is fixedly connected with a plurality of fertilizer boxes 23, in which wood ash is loaded. After harvesting, wood ash can be applied on the cut stubble to facilitate the recovery of the wounds of the leeks.

[0052] By pushing the push rod 4 to cooperate with the multiple universal wheels 5 on the bottom surface of the bottom plate 1, the harvester can be flexibly moved in the leek planting field.

[0053] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0054] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
