Technical Field

[0001] This application relates to the field of seeding device technology, specifically a small-scale combined seeding device integrating trenching, seeding, and soil covering. Background Technology

[0002] In agricultural production, the sowing process plays a decisive role in crop growth. For small-scale farmers and areas with complex terrain and fragmented plots, small combined seeders have become a powerful tool for sowing operations due to their ease of operation and flexibility in adapting to different plots. However, in practical applications, the soil covering and compaction processes of integrated furrowing, sowing, and covering small combined seeders present many problems that urgently need to be solved.

[0003] Traditional small-scale seeding devices often struggle to achieve precise and tight seed coverage. If the soil cover is too thin, the seeds are easily disturbed by external factors; if the soil cover is too thick, it may hinder the seeds from sprouting. In terms of compaction, most existing devices lack an effective compaction mechanism, resulting in insufficient contact between the soil and the seeds, which affects the effectiveness of the equipment.

[0004] Therefore, it is necessary to provide a small-scale combined seeding device that integrates trenching, sowing, and soil covering to solve the above problems. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a small-scale combined sowing device that integrates trenching, sowing, and soil covering, which can improve the soil covering and compaction effects of the device during soil covering.

[0006] The technical solution adopted by this application to solve its technical problem is: a small-scale combined sowing device integrating trenching, sowing, and soil covering, including a sowing component. The sowing component includes a support frame, a hook tooth is provided on one side of the support frame, a support rod is installed on the end bearing of the support frame, a number of sowing boxes are sleeved on the support frame, a chain is fixedly installed on the end of the support frame away from the hook tooth, and movable wheels are fixedly installed on both ends of the support rod. The movable wheel includes a wheel body, a weight ring is fixedly installed on one end of the wheel body, a cavity is opened inside the weight ring, and ball bearings are slidably installed in the cavity of the weight ring.

[0007] Furthermore, the seeding box includes a box body, a sealing cover is fixedly installed on the box body, and several sets of discharge ports are evenly opened at the ends of the box body. The box body can slide left and right on the support rod.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figures 1-4 As shown, this application provides a small integrated planting device for trenching, sowing and covering soil, including a sowing component 10. The sowing component 10 is used for multiple integrated tasks of trenching, sowing and covering soil, thereby improving the overall efficiency of the equipment. At the same time, the sowing component 10 needs to be placed on the soil for preparation, and the whole machine of the sowing component 10 is lightweight, so it can be portable and carried for field operations.

[0028] The seeding assembly 10 includes a support frame 11, which serves as a support structure for the components of the seeding assembly 10. The support frame 11 can be made of welded metal tubing, providing sufficient strength and stability. A fixing strip 15 is fixedly installed on the support frame 11. The fixing strip 15 and the support frame 11 can be combined to form an I-shape. The fixing strip 15 can be used in conjunction with the support frame 11, allowing the components on the support frame 11 to be connected in a concentrated manner. The fixing strip 15 can be made of metal, such as aluminum alloy.

[0029] The support frame 11 has a support rod 13 mounted on its end bearing. Both ends of the support rod 13 are fixedly mounted with movable wheels 18, which can contact the ground. As the wheels roll upon contact with the ground, the entire sowing assembly 10 can move. A pull rod 12 is fixedly mounted on the support frame 11, and its angle can be adjusted freely. Several sets of hook teeth 16 are fixedly mounted on one end of the fixing bar 15. These hook teeth 16 are typically made of high-strength alloy steel and are tilted downwards at a specific angle. During the movement of the sowing assembly 10, they can easily penetrate deep into the soil. As the movable wheels 18 continue to roll, propelling the sowing assembly 10 forward, the hook teeth 16 continuously cut and turn the soil, achieving efficient furrowing. Furthermore, the adjustable angle of the pull rod 12 greatly improves the operator's comfort and operational flexibility.

[0030] Several sets of seeding boxes 14 are sleeved on the support rod 13. Each seeding box 14 includes a box body 141 for storing seeds. A sealing cover 142 is fixedly installed on the box body 141 to seal the inlet of the box body 141. When seeds need to be added to the box body 141, the sealing cover 142 can be opened. After adding seeds, tightening or fastening the sealing cover 142 will complete the sealing.

[0031] The end of the box 141 is evenly provided with several sets of discharge ports 143. When the support rod 13 rotates under the drive of the moving wheel 18, it will drive the box 141 to rotate. Under the combined action of centrifugal force and the weight of the seeds themselves, the seeds inside the box 141 will be evenly scattered through the discharge ports 143. This design realizes the rapid and uniform sowing of seeds, which greatly improves the sowing efficiency and sowing quality compared with the traditional manual sowing method.

[0032] A fixing rod 19 is fixedly installed on the end of the fixing strip 15 near the end of the seed box 14. Several sets of limiting blocks 147 are fixedly installed on the fixing rod 19. At the same time, a fixing ring 144 is installed on the bearing of one side of the box body 141. A collar 145 is rolled on the outside of the fixing ring 144, and a connecting rod 146 is hinged on the collar 145. The end of the connecting rod 146 can be adapted to the limiting block 147. When the end of the connecting rod 146 is inside the limiting block 147, the box body 141 and the fixing ring 144 can be limited on the support rod 13. Although the box body 141 is limited, the bearing connection between the fixing ring 144 and the box body 141, and the rolling connection between the collar 145 and the fixing ring 144 do not affect the normal rotation of the box body 141 around the fixing ring 144 on the support rod 13, ensuring that the seeds can be successfully sown during the sowing process.

[0033] When the position of the seed box 141 needs to be adjusted on the support rod 13, the connecting rod 146 can be removed from the inside of the limiting block 147. Since the connecting rod 146 no longer limits the collar 145 and the connected fixing ring 144 and the seed box 141, the fixing ring 144 loses its limiting constraint. In this state, the operator can slide the seed box 141 and the fixing ring 144 left and right along the length of the support rod 13 to adjust the position of the seed box 14. After the position adjustment is completed, the operator can reinsert the connecting rod 146 into the corresponding limiting block 147 to limit and fix the seed box 14 again, ensuring that the seed box 14 can work stably in the new position, ensuring the accuracy and stability of the sowing operation. At the same time, this design allows the seed box 14 to be flexibly adjusted according to different sowing row spacing, plot shape and other actual conditions, greatly improving the adaptability and practicality of the sowing device.

[0034] A chain 17 is fixedly installed at one end of the support frame 11 away from the hook teeth 16. The chain 17 can contact the soil. When the moving wheel 18 drives the seed box 14 to sow the soil, the chain 17 passes through the soil turned up by the hook teeth 16 to achieve the covering work.

[0035] The movable wheel 18 includes a wheel body 181, with a weight ring 182 fixedly installed at one end of the wheel body 181. The weight ring 182 can add weight to the movable wheel 18, and the inside of the weight ring 182 has a cavity. A ball bearing 183 is slidably installed in the cavity of the weight ring 182. When the wheel body 181 rolls continuously, the ball bearing 183 will always be at the bottom of the weight ring 182 due to the influence of gravity. Thus, the ball bearing 183 can further improve the weight-adding effect of the movable wheel 18. This mechanism not only enhances the stability of the movable wheel 18 itself and prevents swaying or tipping during movement, but also further increases the pressure of the movable wheel 18 on the ground. This design allows the movable wheel 18 to further improve the weight-adding effect on the basis of the original weight of the weight ring 182 through the dynamic adjustment of the ball bearing 183.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
