Description

Weeding mechanism with multiple use modes Technical Field The invention relates to the technical field of weeding machinery, in particular to a weeding mechanism with multiple use modes. Background With the development of agricultural mechanization, the weeding machine plays an important role in agricultural production, and the weeding efficiency and quality are greatly improved. The weeding apparatus currently on the market mainly comprises rotary mowers, reciprocating mowers and the like, and are respectively suitable for a specific type of grassland or weed treatment task. However, these conventional devices generally suffer from a significant problem in that each device is generally only suitable for one or a limited number of specific work scenarios, such as large area lawn maintenance or the removal of specific types of weeds. When facing different kinds of weeds or different working environments, it is often necessary to replace or adjust equipment, and even purchase a specially designed weeder to meet the demand, which not only increases the cost but also limits the operational flexibility. In addition, for the surface weeding work which needs deep weeding or requires higher, the existing equipment is difficult to simultaneously meet the requirements of efficiency and quality, so that the problems of low working efficiency or incomplete weeding and the like are caused. In the prior art, CN111819921A, CN 211210395U et al discloses a weeder with a plurality of groups of weeding mechanisms that straight line array was arranged, and each weeding mechanism all includes blade disc, transmission shaft to and install the cutting knife on the blade disc, through gear drive in order to carry out synchronous rotation between the transmission shaft. The weeding machine has the problems of single use scene and limited applicability. Disclosure of Invention The invention aims to overcome the defects in the prior art, and provides a weeding mechanism with multiple use modes, which can meet abundant weeding demands and has wide applicability. The technical scheme is that the weeding mechanism with multiple use modes comprises a mechanism base body and a plurality of groups of mowing mechanisms arranged on the mechanism base body, wherein all mowing mechanisms can be arranged in a straight line, and the power accessed by one group of mowing mechanisms can be transmitted to other mowing mechanisms through a gear set; The mechanism seat body comprises a middle part and two side parts; each side part can be rotationally folded relative to the middle part, so that the mechanism seat body can be switched between a straight shape and a folded shape, when the mechanism seat body is in the straight shape, the middle part is collinear with all the side parts, all the mowing mechanisms are arranged in a straight line, when the mechanism seat body is in the folded shape, all the side parts are rotationally folded relative to the middle part, all the mowing mechanisms are arranged in front and back two rows, and the two rows of mowing mechanisms are staggered in the left and right directions, and no two groups of mowing mechanisms are aligned front and back; The two ends and the side edges of the mechanism seat body are provided with power output structures, so that when the mechanism seat body is in different forms, the connected power can drive all mowing mechanisms to operate simultaneously. The power output structures at the two ends of the mechanism seat body transmit power to the mowing mechanism on the side part when the mechanism seat body is in a straight shape, and the power output structures at the side edges of the mechanism seat body transmit power to the mowing mechanism on the side part when the mechanism seat body is in a folded shape. When the weeding requirement is low, the mechanism seat body is adjusted into a straight shape, the structures and the heights of all the mowing mechanisms are identical, so that wide weeding can be performed, the weeding efficiency is improved, when the weeding requirement is high and surface weeding is performed, the mechanism seat body is adjusted into a folded shape, the structures and the heights of all the mowing mechanisms are identical, at the moment, the mowing ranges of the front row of mowing mechanisms and the rear row of mowing mechanisms are staggered in the left-right direction, the weeding quality can be effectively improved, the flatness of the mowed grasslands is ensured, when deep weeding is required, the mechanism seat body is adjusted into the folded shape, the structures of the front row of mowing mechanisms and the rear row of mowing mechanisms are different and/or the operation heights are different, so that the front row of mowing mechanisms mainly complete the surface weeding operation, and the rear row of mowing mechanisms complete the grass root removing operation, and the weeding effect can be improved. Further, first butt-joint gears are arranged at t
