[0002] The gourd harvester is mainly used for harvesting seeds of gourds, melons, seed melons and other melons. It can harvest various melon crops growing on the ground. During the harvesting process, the gourd harvester mainly uses the header at the front for harvesting. The harvesting shaft of the header has multiple melon picking teeth. When the harvesting shaft rotates, the gourds are picked up by the picking teeth and removed by the melon remover during the rotation. The fallen melons roll into the collection bin at the rear.

[0003] In the prior art, for example, a swinging blade structure for a melon-beating machine previously applied by our company (publication number CN220733575U) can cut off some of the weeds during operation by setting a swinging blade behind the cutting table, so as to facilitate the subsequent weeding and weeding operations. However, for the above-mentioned prior art, since the swinging blades are arranged in multiple groups and in a horizontal manner, the swinging blades have limited force during actual use, and some of the weeds are difficult to be cut off, so the weeding and weeding effects are limited, and there is still a lot of room for improvement.

[0029] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0030] Example 1

[0031] The present embodiment provides a gourd harvester lower vine beating mechanism. As shown in the reference figure, the lower vine beating mechanism of the present embodiment mainly includes a moving knife assembly 3 and a fixed knife assembly 4.

[0032] The moving knife assembly 3 is arranged at the rear lower part of the cutting platform 1. The cutting platform 1 includes a melon picking shaft, on which a plurality of melon picking teeth are arranged. When the melon picking shaft rotates, the melon picking teeth are used to pick up the gourd or melons. As the melon picking shaft rotates, the gourd or melons are transported upward on the melon picking teeth along with the rotation of the melon picking shaft. At this time, the weeds carried by the gourd or melons pass through the moving knife assembly 3, and the weeds are cut off under the cooperation of the moving knife assembly 3 and the fixed knife assembly 4, so as to avoid a large amount of weeds being transported to the next station with the gourd.

[0033] In this embodiment, the movable blade assembly 3 includes a movable blade shaft 31 and a plurality of movable blades 32. The movable blade shaft 31 can rotate after being supported by bearings at both ends and connected to the power wheel. The axis of the movable blade shaft 31 is parallel to the axis of the melon picking shaft of the cutting table 1. A plurality of movable blades 32 are sequentially arranged at intervals along the axial direction on the movable blade shaft 31, and adjacent movable blades 32 are staggered in the circumferential direction. With the rotation of the movable blade shaft 31, the movable blades 32 can cut off part of the rice weeds during the rotation process, and the part of the cut rice weeds is carried to the position of the fixed blade assembly 4 with the rotation of the movable blades 32.

[0034] In this embodiment, the fixed blade assembly 4 is arranged above the moving blade assembly 3, and the fixed blade assembly 4 includes a fixed blade fixing beam 41 and a plurality of fixed blades 42, wherein the plurality of fixed blades 42 are fixed on the fixed blade fixing beam 41 in sequence, and the fixed blades 42 are U-shaped and open downward, and the moving blades 32 can pass through the gap in the opening of the corresponding fixed blades 42 during the rotation process. In the above structure of this embodiment, when part of the uncut rice weeds are carried to the position of the fixed blades 42 with the rotation of the moving blades 32, because the moving blades 32 need to pass through the U-shaped opening of the fixed blades 42, the rice weeds can be torn or cut off under the action of the fixed fixed blades 42 and the rotating moving blades 32, thereby achieving further cleaning of the rice weeds, with strong cleaning force and good effect.

[0035] Example 2

[0036] Compared with the first embodiment, in the present embodiment, a lower seedling-pulling assembly 2 is added between the cutting table 1 and the moving knife assembly 3. When the cutting table 1 rotates, the seedlings carried by the lower seedling-pulling assembly 2 are moved to the position of the moving knife assembly 3 for further processing.

[0037] As described in the reference figure, the lower seedling pushing assembly 2 includes a lower seedling pushing shaft 21. Both ends of the lower seedling pushing shaft 21 are supported by bearings and are rotatable after being connected to the power wheel. The lower seedling pushing shaft 21 is arranged parallel to the moving knife shaft 31. A plurality of lower seedling pushing rubber plates 22 are arranged on the lower seedling pushing shaft 21 in sequence along the axial direction. The moving knife blade 32 can pass through the gap between the corresponding two lower seedling pushing rubber plates 22.

[0038] In Example 1, the moving knife assembly 3 is directly arranged at the rear of the cutting table 1, and the weeds carried by the cutting table 1 are directly processed by the moving knife assembly 3. However, in order to avoid the moving knife from cutting fruits and vegetables, the moving knife assembly 3 needs to be spaced a certain distance from the rear of the cutting table 1, so some small branches and seedlings are difficult to be directly cleaned by the moving knife assembly 3. In this embodiment, compared with Example 1, the position of the moving knife assembly 3 can be moved backward, and the lower weeding assembly 2 is arranged between the cutting table 1 and the moving knife assembly 3, and the lower weeding assembly 2 can be arranged at a position closer to the cutting table 1. During use, the lower weeding shaft 21 of the lower weeding assembly 2 rotates, and the flexible lower weeding rubber plate 22 pulls off the weeds carried by the rear of the cutting table 1 during the rotation process, and part of the weeding falls to the ground, and part of the weeding enters the position of the moving knife assembly 3 with the rotation of the lower weeding assembly 2, and the movement of the moving knife assembly 3 cuts off the part of the weeding to prevent the weeding from entering the next station.

[0039] In a preferred solution provided in this embodiment, a plurality of long rods 23 are circumferentially arranged on the outer side of the lower seedling moving shaft 21, and the long rods 23 are supported by a plurality of discs 24 fixed on the lower seedling moving shaft 21. A mounting plate 25 is fixedly arranged between the long rods 23 and the lower seedling moving shaft 21, and the lower seedling moving rubber plate 22 is fixedly mounted on the mounting plate 25, so that the entire lower seedling moving assembly 2 has better strength.
