Adopt the produced beneficial effect of above-mentioned technical scheme to lie in:
comb formula fruit picking device:
the utility model designs a comb-comb type picking device according to the characteristic that peanut seedlings are in flexible branch tendril shapes with toughness and peanuts are in larger grains, so as to pick off the peanuts in a comb-comb type picking mode, the comb-comb type picking device consists of more than two picking mechanisms, when the peanut seedlings enter a peanut seedling and fruit picking channel formed by the comb-comb type picking device, because the peanut seedling and fruit picking channel is above, below, left side and right side are relatively closed, each picking roller runs in the same direction under the driving of a transmission device, so that the picking roller movable teeth run in the same direction from front to back in the peanut seedling and fruit picking channel, the peanut seedlings are pulled to the back from the front, because the peanut seedlings are in flexible branch tendril shapes with toughness, the picking roller movable teeth can be wound on the picking roller movable teeth in the backward conveying process, when each picking roller movable tooth passes through a gap between fixed teeth, the fixed teeth on two sides of the picking roller movable teeth can extrude the peanut seedlings and separate the peanut in opposite directions, because the peanuts are large particles and are attached to the relatively flexible peanut seedlings, the peanuts can be extruded from the interior of the peanut seedlings in the extrusion process, and in the splitting process, the peanuts outside the peanut seedlings and the peanuts extruded from the interior of the peanut seedlings are attached (supported) to the peanut seedlings and generate acting force when the peanuts are in front contact with the fixed teeth of the picking roller, so that the fixed teeth of the picking roller generate reacting force on the peanuts to pick the peanuts from the peanut seedlings. The comb-type fruit picking device is used for forcibly kneading and directly acting in the fruit picking process, so that the stems of the peanut seedlings are not affected no matter the stems are dry or wet in the fruit picking process, and the fruit picking mode is different from a beating type separation mode, so that the fruit shell breakage rate is reduced to a great extent; because the fruit picking roller moving teeth are arranged in a radial direction, peanut seedlings are fixed only relative to the circumferential direction of the ring fruit picking roller moving teeth, and the length direction of the fruit picking roller moving teeth is not fixed, when the fruit picking roller moving teeth rotate from bottom to top to carry the peanut seedlings to the upper part of the peanut seedling and fruit picking channel, the fruit picking roller moving teeth of two adjacent fruit picking rollers are mutually embedded into opposite gaps when the connecting line positions of the axes of the rotating shafts of the fruit picking roller rotating shafts of the two adjacent fruit picking rollers are crossed, so that each fruit picking roller closes the upper part of the peanut seedling and fruit picking channel, the peanut seedlings which are carried by the fruit picking roller moving teeth to the upper part are pulled off by the fruit picking roller moving teeth which rotate from top to bottom at the adjacent rear part, and therefore, the peanut seedlings are conveyed backwards by each fruit picking roller moving tooth in the peanut seedling and fruit picking channel, and the peanut seedlings are picked again by the rear fruit picking mechanism for picking the residual peanuts in the peanut seedlings, thereby ensuring the picking rate of the peanuts.
