Description

Clamping conveying structure for garlic harvesting Technical field: the utility model relates to the technical field of garlic harvesting machines, in particular to a clamping and conveying structure for garlic harvesting. The background technology is as follows: The garlic harvester adopts mechanized equipment to complete the agronomic links of garlic digging, soil removing, conveying, finishing, stem cutting, collecting, transferring and the like at one time. The conveying link is mainly carried out in a clamping conveying mode, and finishing and stem cutting work is completed in the conveying process. The existing clamping and conveying structure is generally realized by adopting a belt transmission structure, namely, garlic is clamped by adopting two conveying belts, the garlic is clamped by rotating the conveying belts to be conveyed obliquely upwards, the conveying belts are usually flat belts or V belts, and a specific structure can refer to a single-row stalk-cutting device (authorized bulletin number: CN 115529917B) applied by the company for a garlic harvester. In the prior art, although the garlic clamping and conveying function is realized, the deep technical problem is found in practice, namely the problem that the conveying belt is sometimes fallen off (also called belt falling or separation) in the working process, and the conveying belt needs to be stopped for maintenance once fallen off, which definitely seriously affects the garlic harvesting efficiency. The technical staff has conducted intensive research and analysis to find that the reasons for falling off the conveyer belt are mainly two, firstly, the conveyer belt is obliquely arranged during actual operation because garlic needs to be clamped to move upwards, and compared with a conveyer belt which is horizontally arranged, the conveyer belt is easier to fall off, secondly, sundries such as straw, soil, weeds and the like are easy to wind into the belt wheel during operation of the harvester in the ground, and once the straw, the weeds and the soil are wound on the belt wheel, the falling off problem of the conveyer belt is further aggravated. Therefore, it is necessary to optimize and improve the existing clamping and conveying structure so as to effectively solve the problem of falling of the conveying belt. The foregoing is not necessarily a prior art, and falls within the technical scope of the inventors. The invention comprises the following steps: The utility model aims to solve the problems in the prior art and provide the clamping and conveying structure for garlic harvesting, which has the advantages of reasonable structural design, difficult falling of a conveying belt, good clamping and conveying stability, high clamping and conveying efficiency and the like. The utility model realizes the aim by adopting the following technical scheme: The utility model provides a garlic is gathered with centre gripping conveying structure, includes the frame, horizontal interval is equipped with two centre gripping conveying units in the frame, centre gripping conveying unit includes the upper band pulley and the lower band pulley that vertically interval set up, be equipped with between upper band pulley and the lower band pulley and link group V area, the interval is equipped with a plurality of interior take-up pulleys in the frame between upper band pulley and the lower band pulley, two interior take-up pulley dislocation set in the centre gripping conveying unit, be close to lower band pulley one end in the frame is equipped with outer take-up pulley, two link group V area cooperation centre gripping garlic is carried. Two V belts are arranged on the combined V belt, and two belt grooves are arranged on the upper belt pulley, the lower belt pulley and the inner tensioning wheel which correspond to each other.
