Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting equipment, and in particular relates to a seeder with drip irrigation tape laying function for no-till reseeding operations in the Gobi Desert. Background Technology

[0002] A seeder is a planting machine that sows crop seeds. Currently, most existing seeders are towed seeders, which rely on a tractor or other power equipment in front to move and sow seeds.

[0003] Unlike most of my country's farmland, the Gobi Desert is characterized by high permeability, water scarcity, and sparse vegetation. Crop cultivation in the Gobi requires the installation of drip irrigation tapes. However, existing drip irrigation tape installation and seeding equipment are separate devices, necessitating separate processing during cultivation and reducing production efficiency. Furthermore, traditional seeders require deep plowing and leveling of the land before sowing. Given the fragile ecosystem of the Gobi Desert, deep plowing and leveling are unsuitable. Therefore, a seeding device suitable for no-till reseeding operations in the Gobi Desert needs to be designed. Summary of the Invention

[0004] This invention addresses the problem of low efficiency of existing seeders and drip irrigation laying machines in the Gobi Desert, which require no-till reseeding operations. It proposes a seeder with a reasonable design, simple structure, and integrated drip irrigation tape laying and seeding functions for no-till reseeding operations in the Gobi Desert.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a seeder with drip irrigation tape laying function for no-till reseeding operations in the Gobi Desert, including a frame and a traction frame set at the front end of the frame. The frame is equipped with a seeding leg and a seed storage box set above the seeding leg. The seed storage box is connected to the seeding leg. The frame is also equipped with a furrowing leg set at the front end of the frame. The frame is also equipped with a placement frame with a drip irrigation tape roll set on the placement frame. The frame is also equipped with a drip irrigation tape guide set behind the furrowing leg. The seeding leg is set on both sides behind the drip irrigation tape guide. The soil pushed aside by the seeding leg forms a cover for the furrow opened by the furrowing leg.

[0006] Preferably, the frame is also provided with a flattening roller, which is rotatably mounted at the bottom of the frame.

[0007] Preferably, the flattening roller has gripping teeth spaced apart on its circumferential surface.

[0008] Preferably, the frame is also provided with a braking mechanism for controlling the flattening roller. The braking mechanism includes an arc-shaped brake frame, a brake pad at the bottom of the brake frame, a front end of the brake frame that is axially connected to the frame, and a traveling wheel at the rear end of the brake frame.

[0009] Preferably, the placement rack is provided with at least two drip irrigation tape rolls arranged vertically.

[0010] Preferably, the drip irrigation tape roll is detachably mounted on the placement rack.

[0011] Preferably, the frame is provided with a material preparation rack, and the material preparation rack is provided with a spare seed storage box. The spare seed storage box is located above the seed storage box and is connected to the seed storage box.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] 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 present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figures 1-6 As shown, this embodiment aims to provide a seeder that meets the needs of rapid production in the Gobi Desert, so as to improve the efficiency of sowing and laying drip irrigation tape. In order to achieve the above objective, the seeder with drip irrigation tape laying function for no-till reseeding operations in the Gobi Desert provided in this embodiment includes a frame 1. Like existing seeders, the frame 1 is a rectangular frame structure, and a traction frame 11 is provided at its front end for connecting with the traction hook of the tractor.

[0026] A sowing leg 2 and a seed storage box 3 are installed on the frame 1. The seed storage box 3 is connected to the sowing leg 2. In this embodiment, considering that the sowing depth in the Gobi Desert should not exceed 5cm, the sowing leg 2 is a suspended sowing leg, and a flattening wheel 21 is installed behind it for pushing the soil to bury the seeds. The seed storage box 3 is mainly used to hold the seeds to be sown.

[0027] The above structure is a common structure of existing seeders, therefore, it will not be described in detail in this embodiment.

[0028] Considering that trenching is required to lay drip irrigation tape, trenching legs 4 are also provided on the frame 1. The trenching legs 4 are located at the front end of the frame 1. At the same time, a placement frame 12 is also provided on the frame 1. The placement frame 12 consists of two spaced angle irons, which are fixed to the frame 1 by welding or bolting. A semi-circular groove seat 121 is welded on the placement frame 12. The semi-circular groove seat 121 is made of iron plate or other metal plate bent into a semi-circle. A drip irrigation tape roll 5 is placed between the two semi-circular groove seats 121. The drip irrigation tape roll 5 includes the roll itself and a rotating shaft 51 that passes through the roll. The rotating shaft 51 rests on the semi-circular groove seat 121 to form a detachable and rotatable structure. In this way, only one end of the drip irrigation tape needs to be fixed first. As the frame 1 moves, the drip irrigation tape roll 5 is continuously pulled to rotate, thereby realizing the laying of the drip irrigation tape.

[0029] To ensure the drip irrigation tape falls accurately into the trench created by the trenching leg 4, a drip irrigation tape guide 6 is also installed on the frame 1. The drip irrigation tape guide 6 is located behind the trenching leg 4. It should be noted that in this embodiment, "behind" means that the front and rear are in a straight line. The drip irrigation tape guide 6 can be a flat tube for the drip irrigation tape or a square tube with a guide wheel. Its main purpose is to reduce friction with the frame 1 and to provide guidance. At the same time, a guide pressure roller is installed at the rear end of the trenching leg 4. Its purpose is to press the drip irrigation tape into the trench and, together with the drip irrigation tape guide 6, to prevent the drip irrigation tape from tangling.

[0030] In order to achieve automatic embedding of the drip irrigation tape, in this embodiment, the sowing legs 2 are set on both sides behind the drip irrigation tape guide 6. The sowing legs 2 are set in such a way that the soil pushed into the drip irrigation tape groove by the sowing legs 2 during the movement can form a cover. In this way, the sown seeds are also set close to the drip irrigation tape, so that they can get water better.

[0031] To flatten the ground, in this embodiment, a flattening roller 7 is also provided on the frame 1. The flattening roller 7 is rotatably mounted at the bottom of the frame 1. The axial length of the flattening roller 7 is slightly less than the length of the frame 1. The flattening roller 7 is located behind the drip irrigation tape guide 6. In this way, the drip irrigation tape is placed into the trench and then flattened, which can ensure the stability of the placement and facilitate burial.

[0032] Considering the soil properties of the Gobi Desert, gripping teeth 71 are spaced apart on the circumference of the flattening roller 7 to facilitate its function. The gripping teeth 71 are generally triangular in shape and are fixed to the flattening roller 7 by welding to improve the gripping force of the flattening roller 7.

[0033] Considering that existing seed storage boxes 3 are equipped with a sowing tray at the bottom to control the sowing speed when seeds are added, in this embodiment, a gear is provided on the central shaft of the flattening roller 7, and the gear is connected to a reducer via a chain. A drive shaft 31 is provided at the center of the sowing tray. The drive shaft 31 passes through both sides of the seed storage box 3 and is fixed to the frame 1 via bearing seats. In this way, the reducer and the drive shaft 31 are also connected by a chain, so that the power of the entire seeder comes entirely from the pulling force generated by the tractor's movement.

[0034] When the tractor lifts the drawbar 11, the flattening roller 7 continues to rotate due to inertia. This rotation causes the seeding disc to rotate, resulting in seeds falling and wasting seeds. Therefore, a braking mechanism 8 is installed on the frame 1 to control the flattening roller 7. The braking mechanism 8 includes an arc-shaped brake frame 81 with brake pads 82 at its bottom. The brake pads 82 are elastic sheets such as rubber. The front end of the brake frame 81 is axially connected to the frame 1, and the rear end of the brake frame 81 has a traveling wheel 83. Thus, when the drawbar 11 is lifted, the brake frame 81, under the influence of the weight of the traveling wheel 83, flips downwards, causing the brake pads 82 to press against the flattening roller 7, thus stopping the flattening roller 7 from rotating. During sowing, the brake pads 82, supported by the traveling wheel 83, maintain a certain gap with the flattening roller 7, satisfying the rotation requirements of the flattening roller 7.

[0035] Considering the desolate and uninhabited nature of the Gobi Desert, the planting length can be quite long. Therefore, at least two drip irrigation tape rolls 5, arranged vertically, are installed on the placement frame 12. This eliminates the need to repeatedly retrieve the drip irrigation tape, improving work efficiency.

[0036] Considering that a roll of drip irrigation tape is typically around 2 kilometers long, and the seed storage capacity of seed storage box 3 is insufficient for a single sowing operation, a material preparation rack 13 is installed on the frame 1 to minimize downtime. A spare seed storage box 9 is mounted on the material preparation rack 13, positioned above and connected to seed storage box 3. This increases the seed storage capacity, meeting the needs of a single sowing and laying operation.

[0037] Considering that a single sowing operation is essentially along the length of the drip irrigation tape, and the round trip distance is approximately 2 kilometers, a standing platform 14 is installed at the rear end of the frame 1 for the convenience of the staff. The standing platform 14 is designed in a grid shape. This allows the staff to stand on the standing platform 14. At the same time, an additional horizontal bar is added above the material preparation rack 13, which can be used as a handrail for the staff to hold on to. The grid-shaped design mainly facilitates the vertical insertion of the drip irrigation tape rolls 5, providing more space for the drip irrigation tape rolls 5.

[0038] Through the above setup, not only can the laying of drip irrigation tape and sowing be carried out simultaneously, but also long-distance laying and sowing can be achieved in one go, fully meeting the sowing needs of the Gobi Desert.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
