Description

Technical Field

[0001] The utility model mainly relates to the technical field related to agricultural machinery, and specifically is a cutting table structure of a gourd harvester. Background Art

[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 related patents previously applied by our company (application number 2024209802100, named a gourd harvester seedling removal device), an upper seedling beating mechanism is set on the upper part of the cutting table and a lower seedling beating mechanism is set on the rear of the cutting table to achieve seedling and grass clearing during the harvesting operation of the cutting table. It has been verified that the above technology can greatly improve the effect of seedling and grass clearing, but a small amount of seedling grass will still be retained at the upper seedling beating mechanism. This part of the seedling grass is difficult to be cut off by the existing technology and is easy to be entangled on the cutter and related parts, so it is necessary to further improve the above structure. Utility Model Content

[0004] In order to solve the deficiencies of the current technology, the utility model combines the existing technology and, based on practical application, provides a cutting table structure of a gourd harvester, which can further improve the effect of clearing seedlings and weeds during cutting table operation, avoid the entanglement of seedlings and weeds, and prevent the seedlings and weeds from entering the next process with the fruits.

The eccentric wheel is connected to the output shaft of the power box, one end of the connecting rod is connected to the eccentric wheel and the other end is equipped with a joint bearing, and the other end of the joint bearing is connected to the connecting shaft set at the end of the long strip.

[0008] Furthermore, the rice seedling cutting assembly also includes a front guide rail and a rear guide rail, both of which are fixed on the upper surface of the eccentric plate, a slide groove is arranged between the front guide rail and the rear guide rail, and the long strip plate is slidably matched with the slide groove.

[0009] Furthermore, the scissor blade is in a triangular shape, the tip of the triangle faces the upper movable knife assembly, and both sides of the scissor blade are cutting edges.

[0010] Furthermore, a fixed blade shaft is arranged at the rear of the lower part of the cutting platform, and a plurality of fixed blades are installed on the fixed blade shaft. A moving blade shaft is arranged at one side of the fixed blade shaft, and a plurality of moving blade assemblies are arranged on the moving blade shaft.

[0011] Furthermore, the movable blade assembly includes two movable blades, and a gap is provided between the two movable blades for the corresponding fixed blade to pass through.

DETAILED DESCRIPTION

[0026] 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.

[0027] This embodiment provides a header structure of a gourd harvester, and the corresponding structure diagram is shown in FIG. Figure 1-Figure 7 shown.

[0028] The header structure of the gourd harvester of this embodiment is provided with an upper movable blade assembly 1, an eccentric plate 3 and a seedling row assembly 2 on the upper portion of the header. The upper movable blade assembly 1 includes a rotating shaft, and a plurality of upper movable blades are provided on the rotating shaft. The upper movable blades can cut off the seedlings and grasses when rotating with the rotating shaft. The eccentric plate 3 is located behind the upper movable blade assembly 1. The eccentric plate 3 is provided with a plurality of slots at one end facing the upper movable blades, and the upper movable blades can pass through the corresponding slots during the rotation process. The seedling row assembly 2 mainly uses a rubber plate to push the cut seedlings and grasses onto the conveyor belt at the front end when rotating.

[0029] In this embodiment, as shown in the reference figure, a seedling cutting assembly 4 is provided on one side of the upper movable knife assembly 1 and between the eccentric plate 3 and the seedling rowing assembly 2. The seedling cutting assembly 4 is used for further chopping the seedling grass to avoid the entanglement of the seedling grass.

[0030] The rice-cutting assembly 4 includes a long strip 12, which is arranged along the axial direction of the cutting platform, and a plurality of scissor blades 9 are sequentially installed on the long strip 12, wherein the long strip 12 can drive the scissor blades 9 to achieve reciprocating motion, so that the rice-cutting grass is broken by the scissor blades 9. The reciprocating linear motion of the long strip 12 is driven by the driving assembly, which includes a power box 8, an eccentric wheel 7, a connecting rod 6 and a spherical bearing 5. The input shaft of the power box 8 is connected to the power part, and the eccentric wheel 7 is installed on its output shaft. The two ends of the connecting rod 6 are respectively connected to the eccentric wheel 7 and the spherical bearing 5, and the spherical bearing 5 is connected to the connecting shaft 14 at the end of the long strip 12. The rotational motion of the output shaft of the power box 8 is converted into the reciprocating linear motion of the long strip 12 through the structure of the eccentric wheel 7 and the connecting rod 6.

[0031] In order to ensure the stability of the movement of the long strip 12, the rice cutting assembly 4 also includes a front guide rail 11 and a rear guide rail 13, both of which are fixed on the upper surface of the eccentric plate 3, and a slide groove 15 is arranged between the front guide rail 11 and the rear guide rail 13, so that the long strip 12 slides in the slide groove 15. The scissor blade 9 is triangular in shape as a whole, with its tip facing the upper movable knife assembly 1, and both sides are blades. The scissor blade 9 is attached to the upper surface of the front guide rail 11 and fixed to the long strip 12 by screws. When the scissor blade 9 reciprocates, the rice seedlings and grass are cut.

[0032] In this embodiment, in order to improve the effect of weeding and seedling clearing, the lower seedling beating mechanism is improved. As shown in the figure, a fixed blade shaft 9 is arranged at the rear of the lower part of the cutting platform, and a plurality of fixed blades 10 are sequentially installed along the length direction of the fixed blade shaft 9. A moving blade shaft 17 is arranged on one side of the fixed blade shaft 9, and the moving blade shaft 17 is parallel to the fixed blade shaft 9. A plurality of moving blade assemblies 16 are arranged in an array in the circumferential direction and axial direction of the moving blade shaft 17.

[0033] refer to Figure 7 As shown, the movable blade assembly 16 of this embodiment mainly includes two movable blades 18, and there is a gap between the two movable blades 18. The two movable blades 18 are rectangular plate structures with a certain thickness, bent outward at the upper part, and inclined blades are processed on both sides, and saw teeth 19 are provided on the blades. When the movable blade assembly 16 rotates with the movable blade shaft 17, the fixed blade 10 can pass through the gap between the two movable blades 18, and the fixed blade 10 and the movable blade 18 cooperate to cut the rice weeds carried on the cutting platform. The structural design of the movable blade 18 of this embodiment has a better rice weed cutting effect, a more stable structure, and is not easy to deform.
