Automatic extraction and picking machine for young garlic shoots

Abstract

The invention discloses an automatic garlic shoot extracting and picking machine which comprises a seedling guiding mechanism, a frame, a fixed cross beam, an extracting and picking mechanism, a collecting box, a frame handrail and a cutting-off mechanism, the frame is integrally formed by welding square steel, the frame handrail is fixedly installed at the rear end of the frame through welding, the fixed cross beam is fixedly installed in the center of the end face of the frame through welding, and the cutting-off mechanism is fixedly installed at the rear end of the frame through welding. A plurality of seedling guiding mechanisms are arranged on the bottom end surface of the fixed cross beam; a cut-off mechanism is arranged at the bottom of one end of the seedling guiding mechanism, an extraction mechanism is arranged at the top of one end of the seedling guiding mechanism, and a collecting box is fixedly installed at the position, located on one side of the extraction mechanism, of the center of one end of the seedling guiding mechanism; the automatic garlic shoot extracting and picking machine is reasonable in mechanical structure, simple in overall structure and easy to produce and manufacture; during use, installation, control and operation are flexible and convenient, and maintenance and replacement are convenient; meanwhile, the harvesting efficiency is high, and the harvesting cost of a user can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural harvesting machinery, in particular to an automatic extraction machine for garlic sprouts. Background technique [0002] Most of the existing garlic sprouts are harvested manually, which is low in efficiency, high in cost and labor-intensive. At present, there are also some auxiliary agricultural machines used for harvesting garlic stems, but there are problems of high production cost, complicated structure, and easy damage to garlic plants and affecting the yield of garlic heads. For example, a garlic sedge harvester of Patent Application Publication No. CN101697677B can collect a single row of garlic stalks into bundles, then cut the epidermis at a certain height of the garlic stalks, and transversely cut a certain depth at the cut epidermis. incision and extraction. Although the quality of the garlic sprouts harvested by this method is high, the damage to the garlic plants is relatively ...

AI Technical Summary

Problems solved by technology

However, because the clamping device at the end of the pulling mechanism uses two parallel light-weight short axes to overlap and separate to realize the pulling action, because garlic leaves of a certain thickness grow around the garlic sprouts, it is impossible to distinguish the garlic sprouts from the garlic leaves. When pulling out, it is very easy to pull out the garlic skin together

The second reason is that the garlic sprout cutting device adopts the method of crank intermittent needle piercing. Since the plant spacing of the current garlic plants is not fixed, it is impossible to accurately cut off the garlic sprouts.

And too many needles are too dense, and the cooperation between the needles and the receiving groove is not seamless cutting, so once the garlic sprouts move relative to each other, there will be repeated needles on the garlic stalk, which can achieve multiple cutting effects, and its reeling mechanism is to cut the garlic The plant is bent and then fed into the extraction device, which can easily lead to the breakage of the garlic stalk, and greatly hinder the subsequent growth of the garlic stalk, thus affecting the continued development of the garlic head. Therefore, it is necessary to design an automatic garlic extraction machine of
