Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garlic seeding machine. BACKGROUND

[0002] In 2010, our company submitted a patent application for "a garlic seeding machine", China patent publication number: CN111630987A, publication date September 8, 2020. The product has achieved good market response. Our company's research and development team has conducted long-term in-depth research on the product and found that the technical solution still needs to be further improved:

[0003] 1. The product has the following structure: the garlic seed metering device is embedded with the garlic seed metering box through the garlic seed metering device embedding hole arranged at the bottom of the box body of the garlic seed metering box, and the garlic seed metering device embedding hole is covered by the leather baffle, when the compound seed spoon passes through the garlic seed metering device embedding hole, the leather baffle is lifted up to make it pass through, and after the compound seed spoon passes through the garlic seed metering device embedding hole, the leather baffle falls to cover the garlic seed metering device embedding hole to prevent garlic seeds from falling from the gap between the chain and the garlic seed metering device embedding hole;

[0004] The problem is that when the compound seed spoon passes through the garlic seed metering device embedding hole, the leather baffle is lifted up, which will lift the garlic seeds above the leather baffle to the side, so that the seed spoon cannot take garlic seeds when it just enters the garlic seed metering box from the bottom, thereby affecting the seed taking of the seed spoon, especially when there are few garlic seeds in the garlic seed metering box, the seed spoon will not be able to take garlic seeds, so that the seed spoon will have empty positions, thereby causing the phenomenon of missed seeding during seeding, and at the same time, the compound seed spoon and the leather baffle will also cause wear and tear during friction, increasing the running resistance;

[0005] 2. The product has the above structure and the following structure: the compound seed spoon includes a seed spoon and a seed selection spoon, the cavity of the seed selection spoon can accommodate one garlic seed, the cavity of the seed spoon can accommodate two or more garlic seeds, and the seed spoon picks up multiple garlic seeds in the garlic seed metering box;

[0006] The problem is that the above structure of the seed spoon can only take seeds in the garlic seed metering box, in order to ensure the seed taking accuracy (single), the seed spoon needs to be relatively wide, when there are few garlic seeds in the garlic seed metering box, due to the limitation of the depth of the cavity of the seed spoon, it is possible that no garlic seeds can be taken during upward picking (for example, the garlic seeds above the seed spoon are arranged just at the edge of the cavity of the seed spoon, and the garlic seeds will slide out from the edge during the upward movement of the seed spoon), especially when there are few garlic seeds in the garlic seed metering box, it is easy to miss the garlic seeds;

[0007] 3. The product has the following structure: in order to prevent the garlic seed from rebounding and planting due to the too large distance between the garlic seed discharge port and the bottom of the ditch, the garlic seed discharge port is located in the gap between the left wing fin of the furrow opener and the right wing fin of the furrow opener;

[0008] There are problems: due to the limitation of the shape and structure of the compound seed spoon, the width cannot be arbitrarily reduced, thereby limiting the width of the garlic seed discharge port, and the minimum width between the left wing fin and the right wing fin, and the angle between the left wing fin and the right wing fin cannot be further reduced, the ditching resistance is large, and it is not conducive to energy saving. SUMMARY

[0009] The technical problem to be solved by the present application is to provide a garlic planter which has the characteristics of compact structure, low energy consumption and effectively avoids garlic seed missing and re-planting.

[0012] The compound seed spoon comprises a selecting spoon and a garlic receiving guide plate. The cavity of the selecting spoon can accommodate a garlic seed. In the garlic seed picking section, the opening of the selecting spoon faces backward. The garlic receiving guide plate is located below and behind the selecting spoon. The upper surface of the garlic receiving guide plate is a garlic receiving surface. The garlic receiving surface is smoothly connected with the lower inner wall of the cavity of the selecting spoon. The garlic receiving surface is downwardly inclined from the rear end to the front end, so as to form a garlic seed introduction channel to introduce the garlic seed into the cavity of the selecting spoon. The garlic seeding device is provided with a seed picking structure. The seed picking structure is located at the embedded part of the garlic seed picking section and the garlic seed sowing box. The seed picking structure comprises a seed picking cavity and a garlic seed picking section matched with the seed picking cavity. The gap between the inner wall of the seed picking cavity and the compound seed spoon cannot make the garlic seed slide off. The upper end of the seed picking cavity is in communication with the inner bottom of the box body of the garlic seed sowing box.

After the compound seed spoon in the seed picking cavity is lifted out of the upper end of the seed picking cavity, the garlic seed in the box body of the garlic seed sowing box falls into the seed picking cavity from the upper end of the seed picking cavity. Before the garlic seed falls into the lower end of the seed picking cavity, the next compound seed spoon entering the seed picking cavity blocks the garlic seed. The garlic seed received by the garlic receiving guide plate is introduced into the cavity of the selecting spoon through the garlic seed introduction channel, so that the selecting spoon completes the action of selecting one garlic seed in the seed picking structure.

[0013] The compound seed spoon selected with one garlic seed is lifted into the box body of the garlic seed sowing box, and then is folded forward to enter the garlic seed conveying section conveyed from the rear to the front through the rear chain wheel.

Then, the compound seed spoon is folded downward to enter the garlic seed sowing section conveyed from the top to the bottom through the front chain wheel. The compound seed spoon is correspondingly turned over. The cavity of the selecting spoon is downwardly inclined from the inside to the outside, so that the garlic seed in the selecting spoon slides out of the selecting spoon, falls downward in the closed channel formed in the inner wall of the garlic seed falling prevention cover, and is received on the back of the compound seed spoon below, and is discharged from the garlic seed sowing port.

[0015] When the garlic seeding machine is in operation, a garlic seed dropped from the garlic seed discharge port is received by the garlic receiving body, under the operation of the garlic seed conveying belt, the garlic receiving body conveys the garlic seed downward, and the garlic receiving body is turned over when approaching the bottom of the furrow opened by the furrow opener, and the garlic seed is dropped from the garlic receiving body to the bottom of the furrow in front of the seed furrow holder.

[0016] The garlic seed sowing device further improves that:
