Description

Technical Field

[0001] This utility model belongs to the technical field of vegetable planting equipment, and in particular relates to a direct seeding device suitable for rapeseed seeds. Background Technology

[0002] In the process of conducting rapeseed research or seed production in dryland areas such as Southwest and Northwest China (where water-dryland rotation can eliminate contamination from other rapeseed varieties), contamination from other rapeseed varieties is often encountered. Unlike the water-dryland rotation areas in the Yangtze River Basin, where row sowing is possible, dryland areas usually adopt hill sowing to ensure the purity of research materials. Furthermore, it is important to ensure that the rapeseed varieties are concentrated in one area during hill sowing. This way, the clusters that grow are mainly composed of the rapeseed varieties sown this time, while the scattered varieties growing around them are mostly other rapeseed varieties.

[0003] During hill sowing, manual sowing requires workers to bend over and kneel to place seeds in the planting holes by hand. This often results in back and leg pain after sowing a certain distance, making it very inconvenient for workers. Currently available roller-type rapeseed direct seeders, while ensuring rapeseed is concentrated in one hole, have a large casing, making post-sowing seed removal difficult. They are only suitable for large-scale hybrid seed production. Therefore, there is an urgent need for a direct seeder suitable for small-area rapeseed hill sowing, which can effectively alleviate the hardship of hill sowing and improve operational efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of sowing efficiency and small-area sowing in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A direct seeding device for rapeseed includes an outer shell, inside which a seeding box is installed. A spring hole is provided at the lower end of the seeding box, and a baffle is installed on the side of the spring hole.

[0007] A seed metering cylinder is installed at the lower end of the outer shell. An arc-shaped baffle is provided on the inner side wall of the seed metering cylinder. One end of the arc-shaped baffle abuts against the spring hole to prevent the seeds from falling. A chain is provided inside the seed metering cylinder. Multiple seed slots are installed on the chain and are arranged at equal intervals on the chain.

[0008] A handle is fixedly connected to the left end of the seed metering cylinder. A switch is located at the top of the handle, and a wrench is located at the bottom of the handle. An electromagnetic clutch is installed on the switch, and the electromagnetic clutch is connected to the drive shaft inside the seed metering cylinder.

[0009] A conical cylinder is rotatably connected to the lower end of the seed metering cylinder. A connecting block is installed on one side of the conical cylinder. The connecting block is fixedly connected to one end of a steel wire, and the other end of the steel wire is connected to a wrench.

[0010] Furthermore, a cover is installed on the seeding box.

[0011] Furthermore, the cone tube is composed of two semi-circular conical plates, which are symmetrically distributed on both sides of the bisector of the seed metering tube. When closed, they form a conical seed guiding channel, and when open, they spread the soil to form a sowing space.

[0012] Beneficial effects:

[0013] 1. The direct seeding device designed in this invention can effectively alleviate the hardship of operators and improve work efficiency. Secondly, in rapeseed research and breeding, it is often necessary to sow hundreds or thousands of different numbered samples, with each sample typically requiring only five or ten rows. Using a roller-type direct seeding device is impractical for this purpose. However, with the direct seeding device designed in this invention, after sowing a few rows, the next sample needs to be changed; simply inverting the seeder quickly cleans the seeds and allows for the sowing of the next numbered seed. This is highly user-friendly for planting research and breeding materials.

[0014] 2. Precise and quantitative seed dispensing: Through the coordinated control of the seed trough and baffle, precise seed dispensing is achieved, avoiding missed or repeated sowing. Furthermore, this device is suitable for small-scale scientific research seed production scenarios. Attached Figure Description

[0017] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0018] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] Please see Figure 1 A direct seeding device for rapeseed includes a housing 10, a seeding box 1 installed inside the housing 10, a cover plate 2 installed on the seeding box 1, a spring hole 11 at the lower end of the seeding box 1, and a baffle 12 installed on the side of the spring hole 11.

[0020] A seed metering cylinder 3 is installed at the lower end of the outer shell 10. An arc-shaped baffle 9 is installed on the inner wall of the seed metering cylinder 3. One end of the arc-shaped baffle 9 abuts against the spring hole 11 to prevent the seeds from falling.

[0021] A chain 4 is installed inside the seed metering cylinder 3. The chain 4 is connected to the drive shaft inside the seed metering cylinder 3 via a sprocket. The chain 4 is controlled by a switch 8 and rotates counterclockwise. Multiple seed slots 5 are installed on the chain 4, and the multiple seed slots 5 are arranged at equal intervals on the chain 4. The chain 4 drives the seed slots 5 to rotate. When the seed slot 5 rotates to contact the side baffle 12 of the spring hole 11, it can press the baffle 12, so that the spring hole 11 separates from the arc-shaped baffle 9, and the seeds can fall accurately into the seed slots 5 from the spring hole 11.

[0022] A conical cylinder 6 is rotatably connected to the lower end of the seed metering cylinder 3. The conical cylinder 6 consists of two semi-conical plates, which are symmetrically distributed with respect to the bisector of the seed metering cylinder 3. A connecting block 15 is fixedly connected to one side of the conical cylinder 6. The connecting block 15 is connected to one end of the steel wire 14, and the other end of the steel wire 14 is connected to the wrench 13.

[0023] A handle 7 is installed at the left end of the seed metering cylinder 3. A switch 8 is provided at the top of the handle 7, and a wrench 13 is provided at the bottom of the handle 7. By pulling the wrench 13, the steel wire 14 pulls the conical cylinder 6 to rotate and open, so that the seeds fall from the seed trough 5 into the soil.

[0024] The switch 8 is equipped with an electromagnetic clutch, which is connected to the drive shaft inside the seed metering cylinder 3. When the switch 8 is pressed, the electromagnetic coil is energized, which engages the clutch drive plate with the driven plate on the drive shaft, thereby transmitting power to the drive shaft inside the seed metering cylinder 3. When triggered, the drive shaft drives the chain 4 to rotate one pitch, causing the bottom seed trough 5 to flip upside down and meter the seeds into the conical cylinder 6, while the top seed trough 5 receives the new seeds.

[0025] The working principle of this utility model:

[0026] Place seeds in the seeding box 1, add the materials to be sown into the seeding box 1 all at once, and close the lid 2; the operator holds the handle 7; while holding the handle 7 with one hand, the operator can control the switch 8. When the lifting device is inserted (2-3cm) into the seeding hole, press the switch 8, and the chain 4 will move in a cycle once. The bottom seed trough 5 will flip upside down and discharge the seeds into the seed discharge hole 6, while the top seed trough 5 will receive the seeds. At the same time, pull the wrench 13 to make the steel wire 14 pull the cone 6 to rotate and open. The cone 6 can also open up the soil, allowing the seeds to fall into the soil, thus completing a single sowing.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
