Description

Large-width rotary portal bale plucker based on double-side grabbing Technical Field The invention relates to the technical field of bale pluckers, in particular to a large-width rotary portal bale plucker based on double-side grabbing. Background The bale plucker is an initial device in the blowing-carding process, and has the function of grabbing raw cotton from the arranged cotton bales and conveying the raw cotton to a subsequent processing procedure. The productivity of the bale plucker directly affects the production efficiency of the whole blowing-carding process, so that the improvement of the yield and the flexibility of the bale plucker is an important research direction in the field of textile machinery. Two types of bale pluckers are mainly popular in the market at present, namely a single-arm reciprocating bale plucker and a portal bale plucker, and the two bale pluckers have the structural characteristics and the application scene. The main structure of the single-arm reciprocating bale plucker is that a tower type vehicle body is arranged on a suction groove guide rail, one end of a grabbing arm for grabbing raw materials is arranged on the side surface of the vehicle body, and the other end of the grabbing arm is suspended to form a cantilever structure. In order to balance the moment generated by the cantilever, a movable balance iron device is usually arranged in the vehicle body, and the self weight of the movable balance iron is matched with the self weight of the grabbing arm to maintain static balance. The tower body of the single-arm reciprocating bale plucker can rotate, so that the grabbing arms can turn to the two sides of the suction groove guide rail, and cotton bags can be placed on the two sides of the guide rail when the cotton bags are distributed. However, since the gripping arms are of a single-sided cantilever support structure, when the width of the gripping arms is increased, the deflection and vibration amplitude of the cantilever ends are increased, and the gripping arms are prone to shaking or even overturning risks during operation. Therefore, the single-arm reciprocating bale plucker has difficulty in increasing the yield by increasing the width of the grabbing arm, and the yield is limited by the structure of the grabbing arm. The whole structure of the portal frame type bale plucker is portal frame type, one side frame is arranged on the suction groove guide rail, the other side frame is contacted with the ground or other substrates through wheels, and two ends of the grabbing arms are respectively arranged on the frames at two sides. Because both sides of the grabbing arm are supported, the grabbing arm is not in a cantilever state any more, so that the grabbing arm cannot shake or overturn easily due to the increase of the width, and a portal frame type bale plucker does not need to be provided with a heavy balance iron mechanism. However, the outer frame of the existing portal bale plucker is generally contacted with the ground through wheels arranged parallel to the extending direction of the guide rail, and the portal bale plucker can only do reciprocating linear motion in the front-back direction, so that the grab arm cannot rotate to the other side of the guide rail. Therefore, the portal frame type bale plucker can only grab bales arranged on one side of the guide rail, which is not beneficial to the full utilization of space and the treatment of various raw materials in the same area. In summary, the existing bale plucker has the technical problem that the yield improvement and the bale space arrangement flexibility cannot be considered. The single-arm reciprocating type bale plucker can realize double-side grabbing, but the yield of the single-arm reciprocating type bale plucker is limited by the stability of a cantilever structure, and the portal bale plucker breaks through the limit of the width of the grabbing arm, but the grabbing arm cannot rotate and can only grab at one side. Therefore, a novel bale plucker is needed, which can realize both side support to break through the width limitation of the grabbing arm and realize the rotation of the grabbing arm to meet the requirements of double-side grabbing. Disclosure of Invention In order to solve the problems in the background technology, the invention provides a large-width rotary portal frame type bale plucker based on double-side grabbing, which comprises the following components: the suction groove is used for conveying the grabbed raw materials to the next working procedure; the bale plucker comprises a bale plucker main body, a bale plucker and a bale plucker, wherein the bale plucker main body is arranged on a guide rail of the suction groove, a rotating mechanism is arranged in the bale plucker main body, and the rotating mechanism comprises an internal gear and a planetary gear meshed with the internal gear; One end of the grabbing arm is connected to the side surface of the cotton grabbing
