Description

Technical Field

[0001] This invention relates to the field of field breeding and sowing machinery technology, specifically to an automatic continuous seed changing and metering device for field breeding. Background Technology

[0002] Small plot seeding is a unique agricultural planting method, unlike open field seeding which uses only one type of seed throughout. Small plot seeding typically divides the land into smaller plots, each sown with different seeds. Since each plot is often small, stopping to change seeds after each plot would be time-consuming, and storing different seeds in one place could easily lead to confusion. To facilitate seed changing, our company previously developed several seeders, such as the self-propelled grain small plot seeder proposed in patent application number "CN201910059959.5". However, the seed changing technology in this model relies on manual seed changing, which is inefficient and prone to errors.

[0003] The core technology of the plot seeding planter is to enable automatic and continuous seed switching between different plots, thereby improving the efficiency of seed switching. Summary of the Invention

[0004] This invention provides an automatic continuous seed changing and sowing device for small-scale breeding, which solves the problems of existing small-scale breeding sowing machinery, such as the inability to automatically and continuously switch between different seeds, low seed changing efficiency, and easy errors.

[0005] To address the aforementioned problems, the present invention provides an automatic continuous seed changing and metering device for small-area breeding, comprising a frame, a sliding device on one side of the frame, a seed-carrying device on the sliding device, the seed-carrying device including a seed tray, seed pods, a rotary drive mechanism, and a seed pod pushing mechanism, the seed pods being mounted on the seed tray, and the rotary drive mechanism driving the seed tray to rotate; a seed metering device is provided on the other side of the frame, the seed metering device having seed pod clamps, and seed pod clamp fixing blocks on the seed pod clamps; the seed pod pushing mechanism can push the seed pods into the seed pod clamps on the seed metering device; after the seeds have completely entered the seed metering device, the seed pod pushing mechanism pulls the seed pods back to the seed tray; the lower part of the seed metering device is connected to a seed metering tube, and the lower part of the seed metering tube is connected to a furrow opener; the sliding device drives the seed-carrying device to slide left and right;

[0006] Furthermore, the seed tray is provided with an outer ring, an inner ring, spokes, and a rotating bushing. The outer ring and the inner ring are fixedly installed on the spokes, and the outer ring and the inner ring are each provided with a seed sac fixing block.

[0007] Furthermore, the seed capsule includes a seed capsule cover, a seed storage cavity, and a guide groove. A lower seed cover is provided at the lower part of the seed storage cavity, and an automatic return mechanism is provided inside the lower seed cover.

[0008] Furthermore, the seed capsule clamping fixing block and the guide groove cooperate to fix the seed capsule. When the seed capsule is pushed onto the seed metering device, the seed capsule guide groove fits with the seed outlet at the lower end of the seed capsule. The edge of the seed capsule guide groove pushes open the lower seed cover, and the seeds stored in the seed capsule enter the seed metering device. After the seeds have completely entered the seed metering device, the seed capsule pushing mechanism pulls the seed capsule back to the seed tray.

[0009] Furthermore, the sliding device is provided with a planting tray support device, which is provided with a bracket and rollers. The rollers are mounted on the bracket, and the planting tray support device is located on the lower left and right sides of the planting tray.

[0010] Furthermore, the sliding device includes a support frame, a slide rail, and a drive mechanism. The slide rail is divided into upper and lower parts, which are respectively installed on the frame and the support frame.

[0011] Furthermore, the drive mechanism includes a drive motor and a rack, the drive motor being fixedly mounted on the support frame, and the rack being fixedly mounted on the frame;

[0012] This invention utilizes seed capsules to store different seeds in different capsules. A rotating planting tray automatically and continuously switches the positions of the seed capsules, enabling seed metering and sowing. This invention achieves automatic and continuous seed changing, eliminating the problems of low efficiency and difficulty in controlling manual seed changing during downtime.

The drive mechanism 103 is provided on the sliding device 103. The drive mechanism 103 includes a drive motor 104 and a rack 105. The drive motor 104 is fixedly installed on the support frame 101, and the rack 105 is fixedly installed on the frame, enabling automatic sliding between the frame and the sliding device 100. A seed-carrying device 200 is provided on the sliding device 100. The seed-carrying device 200 includes a seed-carrying disk 201, a seed capsule 202, and a rotary drive mechanism. The machine includes a seed capsule pushing mechanism 203 and a seed capsule pushing mechanism 204. Seed capsules 202 are used to store seeds and are mounted on a seed tray 201. A rotary drive mechanism 203 drives the seed tray 201 to rotate, causing the seed capsules 202 to rotate. Different seed capsules 202 store different seeds, and the rotation of the seed capsules 202 enables automatic seed replacement. On the other side of the frame is a seed metering device 300, which has seed capsule clamps 301 and seed capsule clamp fixing blocks 302. The seed capsule pushing mechanism 204 pushes the seed capsules 202 into the seed capsule clamps 301 on the seed metering device 300. The seed capsule clamp fixing blocks 302 fix the seed capsules 202 in place. As the seed capsules 202 are pushed into the seed metering device 300, the seeds stored in them also enter the seed metering device 300.

[0022] After the seeds have completely entered the seed metering device 300, the seed capsule pushing mechanism 204 pulls the seed capsule 202 back to the seed tray 201. The seed metering device 300 is connected to the seed metering tube at the bottom, and the furrow opener is connected below the seed metering tube. After the seed metering device 300 dispenses the seeds into the seed metering tube, they enter the furrow opened by the furrow opener. The sliding device 100 drives the seed carrier 200 to slide left and right, realizing automatic and continuous seed changing and feeding of different seeds. Through the above, the automatic and continuous seed changing and metering of different seeds is realized, eliminating the need for manual seed changing during machine downtime.
