at present, the picking of garlic shoots still mainly uses manpower, and groove-shaped flat knives are used for cutting off the garlic shoots from the outside of stems of the garlic shoots. The method seriously damages the garlic stems while harvesting the garlic shoots, influences the continuous growth of the garlic in the later period, and reduces the yield of the garlic; in the design of the traditional garlic bolt harvester, the garlic bolt extracting mode is unreasonable in design, and the mode of using a mechanical arm and the like is heavy and complicated and has low efficiency; the design of the seedling separating device is unreasonable, and when the garlic seedling is straightened, the garlic seedling can be seriously damaged; in the past, only one young garlic shoot can be collected at a time, and the efficiency is low; the practical requirements of the farm tools are high, and the application of the image recognition technology which is not mature at present such as high technology is not feasible.

The invention comprises the following steps:

the needle punched garlic bolt harvester consists of cam, needle, Y-shaped steel fork, reverse rake gripper, carding unit, relay, disc drum, frame, central shaft, carriage, accumulator, motor and control switch. The disc roller is supported at the front end of the vehicle body by brackets arranged at two sides of the vehicle frame, and one side of the disc roller is provided with a gear. The disc roller consists of discs and reinforcing steel bars, and is driven by a motor to rotate around a shaft, the discs are positioned at two ends of the roller and perpendicular to the ground, the reinforcing steel bars are arranged between the two discs, and the reinforcing steel bars are perpendicular to the discs and distributed along a circumferential array. The middle of the disc roller is provided with a central shaft, two ends of the central shaft are respectively fixed on the bracket, and the central shaft is provided with a carding device, an inverted rake-shaped clamp holder and a cam. The carding device consists of iron wires perpendicular to the steel bars, the iron wires are compactly arranged, two groups of inverted rake-shaped holders are opposite in position, 180-degree intervals are formed along the circumferential direction, and each group of the inverted rake-shaped holders can be adjusted according to the ditch width of garlic planting and the garlic plant spacing. The clamp holder is inclined forward, and a protruding part is arranged at a specific position along the radial direction of the disc, and the protruding part on the disc can trigger the relay switch when the clamp holder rotates to be about 30 degrees with the vertical direction during the continuous rotation of the roller. According to the ditch width of garlic planting, a plurality of cams on the central shaft are respectively matched with the holders, and each holder is driven by one cam. The puncture needle box is positioned at the lower part of the front end of the vehicle body, the opening is inclined downwards, the specific opening angle is suitable for the fact that the garlic stems can be just punctured when the puncture needles in the puncture needle box are punctured, the Y-shaped steel fork is arranged in the puncture needle box, and the puncture needles are controlled to puncture the garlic bolts by controlling the expansion and contraction of the springs through the electromagnetic relay. The carriage is positioned in the middle of the vehicle body. The storage battery and the motor are positioned at the rear part of the vehicle body, and the motor drives the chain positioned at the side part of the vehicle body and matched with the gear on the disc roller to realize the rotation of the disc roller.

The invention has the beneficial effects that: provides a high-efficiency automatic garlic bolt harvester. By adopting the method of the pricking pin, the survival rate of the garlic after harvesting the young garlic shoots is greatly improved, the research and development cost is low, various machine models can be provided, and the multi-ridge harvesting labor can be saved by matching with agricultural machines such as a small tractor and the like.
