Description

Technical Field

[0001] This utility model relates to the field of seeder technology, specifically to a double-row independent contour-following seeding mechanism. Background Technology

[0002] Existing seeders cannot guarantee consistent sowing depth in complex terrains, and their functions are relatively limited, only capable of performing simple sowing operations. Utility Model Content

[0003] The purpose of this invention is to provide a double-row independent contour-following sowing mechanism. Through the precise linkage of the four-bar contour-following mechanism, the seed metering device can automatically rise and fall with the contour-following movement of the press wheel, regardless of how the ground is uneven, ensuring that the depth of the seeds sown into the soil remains basically consistent, which can solve the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a double-row independent contour-following sowing mechanism, comprising a seed box and a frame, wherein a seed metering device is provided below the seed box, and a seed box connecting frame is provided between the seed metering device and the seed box, wherein the seed metering device and the seed box connecting frame are rotatably connected, and a four-bar contour-following mechanism is provided above the frame, wherein a fixing plate is provided at one end of the four-bar contour-following mechanism, wherein the fixing plate is connected to the frame by bolts, and one end of the seed box connecting frame is connected to the four-bar contour-following mechanism by a pin.

[0005] With the above method, cotton seeds are stored in a seed box, and under the action of gravity and vibration, the seeds flow out through the outlet at the bottom of the seed box;

[0006] The seed metering device releases precisely acquired seeds at designated positions during rotation or reciprocating motion. This ensures accurate seed spacing and prevents missed or repeated sowing.

[0007] Preferably, a seed box adjusting rod is provided on the inner side of the seed box connecting frame. One end of the seed box adjusting rod is rotatably connected to the seed box connecting frame, and the other end of the seed box adjusting rod is combined and connected to a four-bar linkage conforming mechanism.

[0008] Preferably, a press wheel is provided on one side of the seed metering device, and a press wheel connecting frame is provided between the press wheel and the four-bar linkage contouring mechanism, wherein a press wheel adjusting rod is provided on the outer side of the press wheel connecting frame.

[0009] Through the above scheme, the roller first contacts the ground, and its main function is to initially roll and compact the sowing strip, level the seedbed, eliminate large clods and gaps, and create a uniform, firm seedbed environment with suitable moisture conditions for subsequent furrowing, sowing and drip irrigation tape laying.

[0010] Preferably, one end of the press wheel connecting frame is provided with a soil scraper assembly, and the inner side of the soil scraper assembly is provided with a drip irrigation tape laying wheel.

[0011] Preferably, a drip irrigation tape pressing wheel is provided on the outer side of the drip irrigation tape laying wheel, and the drip irrigation tape pressing wheel and the drip irrigation tape laying wheel are connected by a connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the precise linkage of the four-bar linkage contouring mechanism, allows the seed metering device to automatically rise and fall with the contouring movement of the press wheel, regardless of the undulation of the ground, ensuring that the seed is sown into the soil at a basically consistent depth. Moreover, the mechanism is designed with two independent rows, with each row unit floating independently through its own four-bar linkage contouring mechanism, without interfering with each other. This allows each row to maintain an ideal sowing depth independently on horizontally uneven ground, greatly improving adaptability and sowing quality on complex terrain.

[0014] 2. This utility model integrates the drip irrigation tape laying function and the precision sowing function into one mechanism to achieve joint operation; this greatly simplifies the field operation process, saves the time and fuel cost of laying drip irrigation tape separately and returning to sowing, and improves the overall operation efficiency; the method of fixing the drip irrigation tape with shallow soil not only protects the drip irrigation tape, but also facilitates the growth of seedlings in the later stage.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To address the issues of existing seeders' inability to guarantee consistent sowing depth in complex terrain and their limited functionality, which only allows for basic sowing operations; please refer to... Figure 1-2 The present invention provides the following solution:

[0020] A double-row independent contour-following sowing mechanism includes a seed box 2 and a frame 14. A seed metering device 7 is provided below the seed box 2, and a seed box connecting frame 8 is provided between the seed metering device 7 and the seed box 2. The seed metering device 7 and the seed box connecting frame 8 are rotatably connected. A four-bar contour-following mechanism 1 is provided above the frame 14. A fixing plate 13 is provided at one end of the four-bar contour-following mechanism 1. The fixing plate 13 is connected to the frame 14 by bolts. One end of the seed box connecting frame 8 is connected to the four-bar contour-following mechanism 1 by a pin.

[0021] In this embodiment, the entire sowing unit is not rigidly fixed to the frame 14, but is connected to the frame through a four-bar linkage conformal mechanism 1. One end of the mechanism is fixed to the frame 14 with bolts through a fixing plate 13, providing a stable support point; the other end is connected to the seed box connecting frame 8 through a pin.

[0022] When the seeder encounters uneven ground while moving in the field, the press wheel 3, as a grounding component, will move up and down accordingly. Since the press wheel is directly connected to the four-bar linkage 1 through the press wheel connecting frame 10, the up and down movement of the press wheel will drive the entire four-bar linkage to change its configuration around its fixed hinge point.

[0023] A seed box adjusting rod 9 is provided on the inner side of the seed box connecting frame 8. One end of the seed box adjusting rod 9 is rotatably connected to the seed box connecting frame 8, and the other end of the seed box adjusting rod 9 is combined and connected to the four-bar linkage contouring mechanism 1. A pressing wheel 3 is provided on one side of the seed metering device 7. A pressing wheel connecting frame 10 is provided between the pressing wheel 3 and the four-bar linkage contouring mechanism 1. A pressing wheel adjusting rod 11 is provided on the outer side of the pressing wheel connecting frame 10. A soil scraping plate assembly 4 is provided at one end of the pressing wheel connecting frame 10. A drip irrigation tape laying wheel 5 is provided on the inner side of the soil scraping plate assembly 4. A drip irrigation tape pressing wheel 6 is provided on the outer side of the drip irrigation tape laying wheel 5. The drip irrigation tape pressing wheel 6 and the drip irrigation tape laying wheel 5 are connected by a connecting plate 12.

[0024] In this embodiment, the movement of the four-bar linkage will drive the seed box connecting frame 8 connected to its rear pin shaft, as well as the seed box 2 and seed metering device 7 installed on it, to produce corresponding lifting and lowering movements; more importantly, this movement design allows the relative height of the seed metering device 7 relative to the press wheel 3 to remain relatively constant.

[0025] One end of the seed box adjusting rod 9 is rotatably connected to the inside of the seed box connecting frame 8, and the other end is combined with the four-bar linkage contouring mechanism 1. Its main function is to adjust and lock the initial working height of the seed box and seed metering device when static. During the contouring process, it may limit the range or provide auxiliary support to ensure stable floating. The function of the press wheel adjusting rod 11 is similar, used to statically adjust the height of the press wheel relative to the four-bar linkage or frame and set its working reference.
