Description

Double-layer sawtooth delinter Technical Field The invention relates to a double-layer sawtooth delinter. Background The delinter is a type of cotton processing equipment whose basic function is to strip residual lint from cotton seeds after ginning, which is relatively short compared to lint separated from cotton seeds by the gin and is commonly referred to as linters. The flock is typically characterized by a larger specific surface area than lint separated by the gin, so that it is easier to separate the flock by wind force, the means for providing wind force is called a wind nozzle in the lint picker, the wind nozzle being located at the lint picker with a width comparable to the spoke of the lint picker, and shielding the lint picker from the lower side in the up-down direction. Note that the sawtooth linter implements the national standard GB/T21306-2007 "sawtooth linter", which is the most widely used linter at present. Currently, the saw tooth delinter on the market is mainly classified into a single-layer saw tooth delinter and a double-layer saw tooth delinter according to an assembly structure. The double-layer sawtooth delinter is provided with two sets of delinting assemblies, and the two sets of delinting assemblies are in bearing relation in the up-down direction and are divided into an upper layer and a lower layer, wherein the upper layer delinting assembly mainly strips and scrapes two velvet, and the lower layer delinting assembly mainly strips and scrapes three velvet. Typically, as disclosed in chinese patent document CN101781798a, a composite air flow saw tooth linter is essentially a double-layered saw tooth linter, which comprises a mounting base frame, a first layer linter and linter mechanism and a second layer linter and linter mechanism, wherein the first layer linter and linter mechanism is disposed in the middle of the mounting base frame, and the second layer linter and linter mechanism is disposed in the lower part of the mounting base frame and below the first layer linter and linter mechanism. The first-layer velvet stripping and taking mechanism and the second-layer velvet stripping and taking mechanism are the same in structure and at least comprise a box cover, a seed poking part, a velvet stripping part, a velvet taking device, a push rod mechanism and a impurity removing device, wherein a feed inlet of the seed poking part is connected with a discharge outlet of the self-control seed feeding device through a front seed dripping plate of the self-control seed feeding device, the velvet stripping part is arranged below the seed poking part, the impurity removing device is arranged at the rear side of the feed inlet of the velvet taking device, the velvet taking device is an air suction type velvet absorbing device and comprises a velvet absorbing pipe, and the pipe orifice of the velvet absorbing pipe is required to be equivalent to the machine spoke of the velvet stripping machine, so that short velvet stripped by the velvet stripping machine is absorbed in the machine spoke range. Under this condition, in order to avoid being sheltered from by the fine hair suction pipe, the edulcoration device needs to be set up in the top of fine hair suction pipe, simultaneously, receive the shelter from of fine hair suction pipe, and the impurity that first layer shell fine hair and get fine hair mechanism separated also can not fall into second floor shell fine hair and get fine hair mechanism, consequently, two shell fine hair and get fine hair mechanism and all need dispose the edulcoration device. It should be noted that, on the cotton processing line, before the lint is removed, seed cotton cleaning and lint cleaning are performed at least once, most of impurities are removed, the impurities mixed into the seed cotton tend to be heavy impurities with relatively large specific gravity, at this time, the impurity content in the cotton seeds is relatively low, and the two impurity discharging devices are provided, so that the cost is high, and the configuration of the impurity discharging devices is usually too rich from the aspect of the capability of discharging impurities, so that unnecessary waste is generated. In addition, two sets of wind nozzles and two sets of impurity removing devices are required to be arranged in the up-down direction, so that the overall height of the double-layer sawtooth delinter is higher, the number of matched parts is large, the overall structure is complex, and the equipment failure rate is relatively higher. Disclosure of Invention The invention aims to provide a double-layer sawtooth delinter with a relatively compact structure. According to an embodiment of the present invention, there is provided a double-layered saw tooth delinter including: an upper working box, the lower part of which is provided with an upper outlet; An upper rib located at the rear lower side of the upper outlet; An upper saw barrel which is matched with the upper rib t
