Description

[0001] This application is a divisional application of application No. 202210870600.8, titled "Garlic seeding machine", filed on July 22, 2022. TECHNICAL FIELD

[0002] The present application relates to the technical field of garlic seeding machinery. BACKGROUND

[0003] In 2010, our company submitted a patent application for a garlic seeding machine with the invention name "Garlic Seeding Machine", China patent publication No. CN111630987A, published on September 8, 2020. The product has received good market response. Our company's R&D team has conducted long-term in-depth research on this product and found that the technical solution still needs further improvement:

[0004] 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. 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;

[0005] The problem is that when the leather baffle is lifted up when the compound seed spoon passes through the garlic seed metering device embedding hole, the garlic seeds above the leather baffle will be lifted to the side. Therefore, 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 selection spoon will have empty positions, thereby causing the phenomenon of missed seeding during seeding. At the same time, it will also cause wear and tear of the compound seed spoon and the leather baffle during friction, and increase the running resistance;

[0006] 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, and the cavity of the seed spoon can accommodate two or more garlic seeds. The seed spoon picks up multiple garlic seeds in the garlic seed metering box;

[0007] There is a problem that the above-mentioned structure can only take seeds in the garlic seed box, in order to ensure the seed taking precision (single), the seed spoon needs to be relatively wide, when there are few garlic seeds in the garlic seed box, due to the limitation of the cavity depth of the seed spoon, it is possible that the garlic seeds cannot be taken (for example, the garlic seeds above the seed spoon are arranged at the edge of the cavity of the seed spoon, and the garlic seeds will slide outwards from the edge during the upward process of the seed spoon), especially when there are few garlic seeds in the garlic seed box, it is easy to miss the garlic seeds;

[0008] 3. The product has the following structure: in order to prevent the garlic seed from rebounding and jumping due to the too large distance between the garlic seed seed outlet and the bottom of the ditch, the garlic seed seed outlet is located in the gap between the left wing fin of the furrower and the right wing fin of the furrower;

[0009] There is a problem that due to the limitation of the shape and structure of the composite seed spoon, the width cannot be arbitrarily reduced, so the width of the garlic seed seed outlet is limited, and the minimum width between the left wing fin and the right wing fin is also limited, the included angle between the left wing fin and the right wing fin cannot be further reduced, the ditching resistance is large, which is not conducive to energy saving.
