AI Technical Summary
In existing technologies, the removal of onion stems and leaves requires manual cutting, which is labor-intensive, inefficient, and can easily damage intercropped crops, increasing production costs.
A shredder for scallion stems and leaves suitable for intercropping was designed. It uses two rotating blade rollers on the left and right sides at high speed. Through the combination of large and small blade discs and seedling-killing blades, it ensures that the scallion stems and leaves are shredded without damaging the intercropped crops.
It achieves efficient shredding of onion stems and leaves without harming intercropped crops, reducing labor intensity and production costs.

TECHNICAL FIELD
[0001] The utility model relates to agricultural machinery field, especially a kind of hair onion stem and leaf pulverizer. BACKGROUND
[0002] At present, according to the investigation statistics in the harvesting process of hair onion, hair onion stem and leaf need to be cut off by artificial after hair onion is dug, there is no special mechanical equipment, can only be cut off by scissors, 2 mu or so stem and leaf can be cut off per day per person, and the working efficiency is low in the extremely poor operation environment in the hottest season of harvest season, there is the problem of great labor intensity. Only stem and leaf shearing removal work reaches 0.4-0.6 ten thousand yuan per hectare, about 14% of the entire hair onion production cost 30 thousand yuan per hectare, so that hair onion production cost is high. Reducing the cost of hair onion production, improving the benefit of hair onion planting, realizing the mechanized production of hair onion planting, and pointing out the direction of hair onion production technology for farmers are imminent.
[0003] Due to the different planting agronomy of hair onion in different places, farmers in Changchun Halahai Town adopt the way of interplanting to plant hair onion in order to increase the utilization rate of land and improve the income, that is, soybean or cabbage is planted in the ridge ditch between two ridges of hair onion, and each row is planted, so the interplanting mode increases the difficulty of stem and leaf removal during hair onion harvesting. The utility model is dedicated to solving the problem of removing stem and leaf while harvesting hair onion without damaging interplanted crops, and designs an interplanting hair onion stem and leaf pulverizer. SUMMARY
[0004] The utility model relates to the technical problem that is designed to the hair onion stem and leaf pulverizer of interplanting that can be suitable for the shortcoming in prior art. A kind of hair onion stem and leaf pulverizer suitable for interplanting, characterized in that the hair onion stem and leaf pulverizer of the present application comprises a rack (1), a pair of ground wheels (2) is arranged at the rear of the rack, a gearbox (3) is arranged on the rack, each of the left and right ends of the gearbox has an output shaft (4), the left and right output shafts are connected with the shafts where the large pulleys (6) on the left and right sides through left and right two universal joint couplings (5), the left and right two large pulleys drive the left and right two small pulleys (7) through linkage, the small pulleys on the left and right sides are installed on the shafts where the cutter rollers (8) are located to drive the cutter rollers to rotate at high speed, a certain gap is left between the cutter rollers through the baffle (9), to prevent the interplanted crops between the two ridges of hair onion from being pulverized, the small cutter disc (10) and the large cutter disc (11) on the cutter roller are welded on the cutter shaft, and the killing blade is installed on the small cutter disc and the large cutter disc, and the killing blade is divided into straight blade (12) and bent blade (13). The utility model has the beneficial effect that the machine can pulverize hair onion stem and leaf without damaging the interplanted crops in the middle.
[0005] The three large cutter discs and two small cutter discs (10) are arranged on each side of the cutter roll, the cutter discs are circular, and straight blades (12) are arranged on the large cutter disc (11) near the ground wheel side, and the rest of the cutter discs are provided with bending blades (13).
[0006] The straight blade (12) is made of Q235 material, and has a length of 170cm and a width of 50cm. BRIEF DESCRIPTION OF DRAWINGS
