Description

A clamping and cutting garlic seedling separation device and its working principle

technical field

The invention relates to the technical field of agricultural machinery and equipment, in particular to a device for separating garlic seedlings.

Background technique

Garlic is an important vegetable crop and economic crop in my country. Harvesting is an important part of the garlic production process. The amount of labor accounts for more than 1/3 of the whole production process, and the operating cost accounts for more than 50% of the total cost. At present, most domestic garlic harvesting areas are still dominated by manual labor. Manual harvesting has low efficiency, high labor intensity, and high harvesting costs, which seriously restrict the development of my country's garlic industry. Most of the garlic excavated by traditional manual digging or mechanical excavation is placed in the field, and the harvested fresh garlic will deteriorate and change color when exposed to the sun for a long time. It takes a lot of manpower to cut the garlic as soon as possible and collect the garlic. Harvesting garlic and separating fruit and seedlings account for more than 40% of the workload, which consumes a lot of manpower and time, and there are potential safety hazards in manual operation. Mechanized combined harvesting is currently the most integrated garlic mechanized harvesting technology, and it is also the development direction of garlic harvesting mechanization in my country. The separation of fruit seedlings is the most core and most technically difficult operation process in garlic combined harvesting. The quality of the separation effect depends directly on It determines whether the harvested garlic needs to be processed by manual secondary seedling cutting. Although developed countries have realized the whole process of mechanized harvesting of garlic, due to the small planting area, there are few machines dedicated to garlic harvesting, especially equipped with fruit seedling separation mechanisms, and there are few equipments that can complete the fruit seedling separation process. Therefore, it is the focus of research and development of the current garlic combined harvesting technology to overcome the separation technology of garlic combined harvesting fruit seedlings and improve the yield of garlic combined harvesting fruit seedlings separation.

It avoids the loss of garlic pods caused by falling off from the clamping chain when the fruit seedlings do not reach the cutting position during the driving process of the fruit claw; the positioning pin on the fruit claw is inserted into the upper limit hole of the cutting blade, so that the cutting blade can Translate along the upper surface of the fruit claw to realize the adjustment of the relative position of the cutting blade and the fruit claw, and then realize the real-time cutting of garlic seedlings; the position adjustment of the cutting blade is realized by pushing the fixed pin through the connecting rod hinged with the shaft sleeve. The bottom surface of the fruit claw is under pressure, pushing the connecting shaft and the cutting blade to move upward, the connecting rod hinged on the sleeve pushes the cutting blade to move radially inward through the fixed pin, and cooperates with the fruit claw to cut off the fruit seedlings. The garlic fruit depends on its own weight When it falls down, the pressure at the bottom of the fruit claw disappears, and the connecting shaft drives the cutting blade to move down through the spring, and at the same time, the connecting rod drives the cutting blade to move radially outward and reset through the fixed pin, so as to prepare for the next clamping and cutting. Through the mutual cooperation of various components, operations such as clamping and lifting of garlic seedlings, cutting and separation, and garlic blanking can be completed automatically. The entire equipment has high working efficiency, good uniformity for garlic separation, and high yield. Garlic does not need to be cut seedlings again.
