Description

Technical Field

[0001] This utility model belongs to the field of seeder technology, specifically relating to a deep tillage seeder. Background Technology

[0002] A seed drill is a planting machine that sows crop seeds. Seeders used for a specific type or crop are often named after the crop type, such as grain row seeders, corn hill seeders, cotton seeders, and hay spreaders. Currently, most farmers use deep tillage machines to deeply till their fields, turning over the deeper soil layers and covering the shallower ones. This increases soil porosity, improves soil structure, and enhances the soil's ability to retain fertilizer and water, which is beneficial for root growth and development. Deep tillage also removes weeds, improves soil fertility, reduces the prevalence of pests and diseases, and promotes healthy crop growth.

[0003] Most existing seeders use a fixed transmission structure, with the transmission components and seeding unit rigidly connected. The number of rows and row spacing are determined at the factory, and users cannot adjust the number of seeding rows according to crop type (such as corn, wheat, soybean) or soil conditions (such as sandy soil, clay soil). The overall practicality of the device is poor. Therefore, a deep tillage seeder is needed to help solve this problem. Utility Model Content

The positioning rod of the adjustment component, through the cooperation of the lead screw and the arc groove of the guide block, can quickly fix the position of the rotating handle, avoiding adjustment failure caused by vibration during operation.

[0005] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a deep tillage seeder, which includes a mounting frame, with movable wheels rotatably arranged on both sides of the mounting frame, rotating wheels equidistantly arranged on the mounting frame, a guide box installed at the top of the mounting frame, a receiving cavity opened inside the guide box, the receiving cavity being funnel-shaped in general, and discharge outlets equidistantly opened on the inner side of the receiving cavity; A transmission assembly is installed on the outer side of the conductive box corresponding to the outlet.

[0016] 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.

[0017] This specific implementation is a deep tillage seeder, such as... Figure 1-5 As shown, the deep tillage seeder includes a mounting frame 1, with movable wheels 14 rotatably mounted on both sides of the mounting frame 1, and rotating wheels 10 rotatably mounted at equal intervals on the mounting frame 1. A first inclined frame 2 is mounted at the middle of the front end of the mounting frame 1, and a connecting rod 3 is hinged to the front end of the first inclined frame 2. A fixed frame 5 is hinged to the top of the first inclined frame 2, and a fixed rod 6 is installed at an angle between the mounting frame 1 and the fixed frame 5. A hydraulic rod 4 is installed at an angle hinged between the top of the first inclined frame 2 and the fixed frame 5.

[0018] The hydraulic rod 4 at the front end of the mounting frame 1, together with the fixed frame 5 and the first inclined frame 2, forms a triangular support structure. The overall height of the mounting frame 1 can be precisely controlled by hydraulic adjustment, thereby adjusting the hidden structure of the furrow opener and the unmarked soil penetration depth. This integrates deep tillage and sowing functions, avoiding the problem of traditional seeders requiring multiple operations, reducing soil compaction, and facilitating seed germination.

[0019] A conductive box 11 is installed at the top of the mounting bracket 1. A top cover 12 is hinged to the top of the conductive box 11. The conductive box 11 has an internal cavity, which is funnel-shaped. Discharge outlets are equidistantly provided on the inner side of the cavity. A spiral rotating rod 13 is rotatably installed inside the cavity. A motor that drives the rotating rod 13 and the rotating rod 8 to rotate is installed on the outer side of the conductive box 11.

[0020] The funnel-shaped receiving cavity in the guide box 11, combined with the spiral rotating rod 13, utilizes the dual effects of gravity and mechanical propulsion to ensure continuous flow of seeds from the top to the bottom discharge outlet, avoiding blockage problems caused by seed accumulation or bridging. The spiral design allows seeds to be transported along a fixed path, reducing randomness and providing a stable foundation for subsequent quantitative sowing.

[0021] A transmission assembly 7 is installed on the outer side of the conductive box 11 corresponding to the outlet. The transmission assembly 7 includes an installation cylinder 71 installed on the conductive box 11, a conductive tube 72 installed at the bottom of the installation cylinder 71, a rotating disk 73 rotatably mounted inside the installation cylinder 71, and a receiving block 74 protruding from the outer edge of the rotating disk 73. Several receiving blocks 74 are arranged in a circular array around the center of the rotating disk 73. The receiving blocks 74 have storage cavities for storing seeds. A transmission cavity is provided at the center, and a limit strip 75 protrudes from the inner side of the transmission cavity. One end of the rotating rod 8 extends into the transmission cavity, and a transmission gear 81 is fixed in the transmission cavity corresponding to the rotating rod 8. The transmission gear 81 and the limit strip 75 are engaged and fixed. A receiving cavity for accommodating the transmission gear 81 is provided on one side of the mounting cylinder 71. A top pressure spring 82 is installed at one end of the rotating rod 8 to assist the rotating rod 8 in pressing down. The top pressure spring 82 provides axial preload to the transmission gear 81 to ensure that there is no loosening during transmission.

[0022] The rotating disk 73 of the transmission assembly 7 is designed with a circular array of receiving blocks 74. Each storage cavity 741 has the same volume. The rotating disk 73 can complete the placement of a fixed number of seeds with each rotation. The engagement between the transmission gear disk 81 and the limiting strip 75 ensures that the power of the rotating rod 8 is efficiently transmitted to all transmission assemblies 7, realizing synchronous sowing of multiple rows and significantly improving the consistency of row spacing. Furthermore, an adjustment assembly 9 for adjusting the position of the rotating rod 8 is installed on the outer side of the conductive box 11. The adjustment assembly 9 includes a rotating handle 91 hinged to the outer side of the conductive box 11, a guide block 92 installed on the outer side of the conductive box 11, and a rotating handle 91 hinged to the rotating rod 8 at one end near the rotating rod 8. A lead screw is fixed on the outer side of the rotating handle 91. An arc-shaped groove for the lead screw to slide is opened on the guide block 92. A positioning rod 93 is threaded on the lead screw. The bottom of the positioning rod 93 is pressed against the outer side of the guide block 92. An embedding block is embedded at the outer edge of the rotating rod 8. An installation rod is protruding from the outer edge of the embedding block. An elongated oval installation groove is opened at the end of the rotating handle 91 facing the embedding block. The installation rod and the installation groove slide together. When the rotating handle 91 is rotated, the embedding block can be adjusted to achieve the overall adjustment of the rotating rod 8.

[0023] By adjusting the handle 91 within the arc-shaped groove of the guide block 92, the lateral position of the rotating rod 8 can be quickly adjusted using the adjustment component 9. This allows the transmission gear plate 81 to engage or disengage with the transmission components 7 at different positions, enabling flexible selection of the number of sowing rows (single, double, or multiple rows) based on crop type or soil conditions, thus adapting to different agronomic needs. The positioning rod 93 of the adjustment component 9, through a lead screw engaging with the arc-shaped groove of the guide block 92, can quickly fix the position of the rotating handle 91, preventing adjustment failure due to vibration during operation.

[0024] Working principle: Seeds are poured into the receiving cavity of the guide box 11 through the top cover 12. The funnel-shaped structure of the receiving cavity causes the seeds to naturally gather at the bottom. The motor drives the spiral rotating rod 13 to rotate, and the rotating rod 13 evenly transports the seeds from the bottom of the receiving cavity to each discharge outlet.

[0025] The rotating handle 91 of the adjusting component 9 slides in the arc groove of the guide block 92, driving the rotating rod 8 to move laterally, so that the transmission gear 81 at the end of the rotating rod 8 is inserted into the transmission cavity 731 of the transmission component 7. The transmission gear 81 is locked and fixed with the limiting strip 75. When the motor drives the rotating rod 8 to rotate, the rotating disk 73 rotates synchronously. The receiving block 74 on its outer edge passes through the discharge port in sequence. The storage cavity 741 of the receiving block 74 quantitatively scoops up the seeds and rotates with the rotating disk 73 to the opening of the guide tube 72. The seeds fall into the soil through the guide tube 72.

[0026] The hydraulic rod 4 extends and retracts, pushing the fixed frame 5 to rotate around the top hinge point of the first inclined frame 2, thereby driving the connecting rod 3 to adjust the angle between the first inclined frame 2 and the ground, thus changing the overall height of the mounting frame 1 and adjusting the sowing depth. The fixed rod 6 provides auxiliary support to ensure structural stability.

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
