Description

Technical fields:

[0001] This utility model relates to the technical field of garlic harvesting equipment, specifically to a garlic harvesting device. Background technology:

[0002] The stalk lifter is an essential component of a garlic combine harvester. Its main function is to straighten the garlic plants and guide them to the stalk-pulling and cutting mechanism. For example... Figure 6 The image shown is a previously disclosed crop straightening device by our company. Its structure mainly includes a support, a support rod rotatably mounted on the support, and a sliding plate (support plate) rotatably mounted at the front end of the support rod. The sliding plate is equipped with a primary crop straightening rod and a secondary crop straightening rod, and the support rod is equipped with a tertiary crop straightening rod. This structural design has initially achieved the expected technical effect, enabling timely and accurate straightening of garlic. For details, please refer to our company's previously applied-for crop straightening device for garlic harvesting (authorization announcement number: CN218337167U).

[0003] The aforementioned crop straightener achieved good results after being applied to garlic combine harvesters, especially in straightening lodged garlic. However, subsequent practice revealed deeper technical problems: when there were small pits or mounds of soil in the tilled land, the sliding plate could easily become uncontrollable, causing it to fail to return to horizontal movement, bend, or even break in some areas. These small pits or mounds of soil in the tilled land are mainly generated during planting and irrigation operations. After in-depth analysis and research, technicians concluded that... Figure 6 As shown, when the skateboard just passes over the small pit, because the skateboard rotates freely relative to the support rod, its front end will tilt downwards as it passes over the pit. The front end of the skateboard and the first-stage lifting rod will then insert into the pit. This not only prevents the first-stage lifting rod from functioning properly but also obstructs the skateboard's forward movement and causes impact damage. This impact can easily lead to bending and deformation of the first-stage lifting rod and damage to other components. Therefore, it is necessary to improve and optimize the existing lifting device.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Summary of the Invention:

[0005] The purpose of this utility model is to solve the problems existing in the prior art and provide a garlic harvester with advantages such as reasonable structural design, high structural strength, the ability of the pallet to maintain a horizontal posture while moving forward, long service life, and good harvesting effect.

[0006] This utility model achieves the above objectives by adopting the following technical solutions:

[0007] A garlic harvesting support includes a support mounted at the front end of a harvester frame. A support rod is rotatably mounted on the support, and a tray is fixedly mounted at the front end of the support rod. A limiting bolt is mounted on the support, and a downward pressing rod is mounted at the upper end of the tray. The downward pressing rod is movably mounted on the harvester frame via a spring. A front supporting rod is mounted at the front end of the downward pressing rod, and rear supporting rods are mounted on both sides of the support rod. The spring drives the tray and support rod to rotate downwards via the downward pressing rod, and the limiting bolt limits the downward rotation of the support rod.

[0008] The support rod is rotatably mounted on the support via a pin. A locking nut is fixedly mounted on the support. The limiting bolt is installed on the locking nut, and the lower end of the limiting bolt acts on the support rod.

[0009] The two ends of the pallet are bent upwards to form a front bend and a rear bend, and the front bend is designed as a triangle.

[0010] The lower pressure rod is located at the upper end of the front bend. The puller frame is provided with a waist-shaped hole. The rear end of the lower pressure rod is installed on the waist-shaped hole. A retaining ring is provided on the lower pressure rod. A spring is provided on the lower pressure rod between the puller frame and the retaining ring.

[0011] The front end of the pressure rod is bent downwards at an angle to form the front support rod.

[0012] The front straw is designed in a straight line or an L-shape.

[0013] The rear straw bends away from the support rod while also tilting upwards.

[0014] A reinforcing connecting rod is provided between the front bend and the support rod.

[0015] The present invention, by adopting the above-described structure, can bring the following beneficial effects:

[0016] (1) By fixing the pallet to the support rod, the pallet can maintain a horizontal posture and move forward under the action of the spring, the lower pressure rod and the limiting bolt. When passing through a small pit, the front end of the pallet will not tilt down, but will maintain a horizontal posture and pass through the pit. When passing through a small mound, the pallet and the support rod will rotate upward briefly. After passing through the small mound, it will return to a horizontal posture and move forward under the action of the spring. (2) Remove the secondary lifting rod in the existing rice lifter, and only retain the front lifting rod and the rear lifting rod. The front lifting rod is directly set at the front end of the lower pressure rod, and the distance between the rear lifting rod and the front lifting rod is shortened. While ensuring the lifting effect, the structure is simplified and optimized, and the production cost is reduced. Attached image description:

Detailed implementation method:

[0024] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0026] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0027] Furthermore, terms such as “horizontal,” “vertical,” “upper,” and “lower” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the location of the indicated technical feature.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figure 1-5 As shown, a garlic harvesting loader includes a support 2 located at the front end of a harvester frame 1. The harvester frame 1 is a component of the harvesting and stalk-cutting mechanism on a garlic combine harvester. A support rod 3 is rotatably mounted on the support 2. A support plate 4 is fixedly mounted at the front end of the support rod 3. A limiting bolt 5 is provided on the support 2. A downward pressure rod 6 is located at the upper end of the support plate 4. The downward pressure rod 6 is movably mounted on the harvester frame 1 via a spring 7. A front loader 8 is located at the front end of the downward pressure rod 6. Rear loader 9 are located on both sides of the support rod 3. The spring 7 drives the support plate 4 and support rod 3 to rotate downwards via the downward pressure rod 6. The limiting bolt 5 limits the downward rotation of the support rod 3, thereby achieving the purpose of keeping the support plate 4 in a horizontal position. By fixing the support plate 4 to the support rod 2, the support plate 4 can maintain a horizontal position and move forward under the action of the spring 7, the downward pressure rod 6, and the limiting bolt 5. Figure 4 As shown, when passing over the small pit 19 on the cultivated land 18, the front end of the pallet 4 will not tilt down, but will remain horizontal as it passes over the pit 19. Figure 5 As shown, when passing over the small mound 20 on the cultivated land 18, the support plate 4 and the support rod 3 will briefly rotate upwards. After passing over the small mound 20, they will return to a horizontal posture and move forward under the action of the spring 7. Here, cultivated land 18 refers to land where garlic is grown. The secondary lifting rod in the existing lifting device 17 is removed, leaving only the front lifting rod 8 and the rear lifting rod 9. The front lifting rod 8 is directly set at the front end of the lower pressure rod 6, and the distance between the rear lifting rod 9 and the front lifting rod 8 is shortened. While ensuring the lifting effect, the structure is simplified and optimized, and the production cost is reduced.

[0030] The support rod 3 is rotatably mounted on the support 2 via a pin 10. A locking nut 11 is fixedly mounted on the support 2, and a limiting bolt 5 is installed on the locking nut 11. The lower end of the limiting bolt 5 acts on the support rod 2. The rotational movement of the support rod 3 is restricted by the limiting bolt 5.

[0031] The two ends of the pallet 4 are bent upwards to form a front bend 12 and a rear bend 13, respectively. The front bend 12 is designed in a triangular shape. The design of the front bend 12 and the rear bend 13 facilitates gliding forward close to the ground. The triangular design of the front bend 12 can connect the front supporting stalk 8 and the rear supporting stalk 9 well, thus making the supporting of the rice more smooth and the supporting effect better.

[0032] The lower pressure rod 6 is located at the upper end of the front bend 12. The puller frame 1 has a waist-shaped hole 14. The rear end of the lower pressure rod 6 is installed on the waist-shaped hole 14. The lower pressure rod 6 has a retaining ring 15. A spring 7 is installed on the lower pressure rod 6 between the puller frame 1 and the retaining ring 15. The lower pressure rod 6 has a certain amount of room to move within the waist-shaped hole 14. With the help of the spring 7 and the lower pressure rod 6, the support plate 4 can rotate upward briefly. This structure facilitates smooth passage over the small mound 20.

[0033] The front end of the lower pressure rod 6 is bent downwards at an angle to form the front supporting rod 8. The front supporting rod 8 and the lower pressure rod 6 are integrally molded, which not only has high structural strength, but also makes installation more convenient, requiring only one welding.

[0034] The front straw stalk 8 is designed in a straight line or an L-shape (e.g., ...). Figure 3 (As shown). The shape of the front straw 8 is selected according to the specific application. From a process perspective, the "I" shape is preferred, as it is more cost-effective.

[0035] The rear supporting stalk 9 bends away from the support rod 3 while also tilting upwards. This structural design not only helps to support the garlic but also guides the garlic into the harvesting and stalk-cutting mechanism.

[0036] A reinforcing connecting rod 16 is provided between the front bending portion 12 and the support rod 3 to enhance the connection strength between the support plate 4 and the support rod 3.

[0037] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0038] Any aspects of this utility model not described in detail are known to those skilled in the art.
