The purpose of the utility model is realized like this: the utility model provides a ware is thrown to miscellaneous surplus in maize picker cleaning plant, it mainly comprises spare parts such as last jib, lower jib, frame, round hole sieve down, last round hole sieve, miscellaneous surplus throwing ware dial roller, miscellaneous surplus throwing ware group finger, belt pulley bearing, band pulley A, connecting rod B, drive belt, band pulley B, crank, its characterized in that: the upper round hole sieve is fixedly connected with the frame of the cleaning device through an upper suspender, the lower round hole sieve is fixedly connected with the frame of the cleaning device through a lower suspender, one end of a connecting rod A is hinged with the upper round hole sieve, the other end of the connecting rod A is hinged with the lower round hole sieve, one end of a connecting rod B is hinged with a crank, the other end of the connecting rod B is hinged with the upper round hole sieve to form a crank-connecting rod mechanism, the sundry throwing device poking roller is sleeved at the front end of the cleaning device frame through a bearing with a seat, and is fixedly connected with the cleaning device frame and positioned at the upper side of the upper round hole sieve, the mixing and residue throwing device poking fingers are orderly arranged on a mixing and residue throwing device poking roller according to a certain rule, one end of the mixing and residue throwing device poking roller is provided with a belt wheel A, the belt wheel B is arranged at the same side end of the crank, and the belt wheel A is connected with the belt wheel B through a transmission belt, so that the pulling roller of the impurity throwing device and the crank rotate together, and the impurity throwing device mechanism in the cleaning device of the corn harvester is formed.

Maize picker cleaning plant in miscellaneous throwing ware install in cleaning plant shale shaker upper portion space, can assist to accomplish the screening to big feeding volume material, reach seed grain and miscellaneous effect of remaining in layering in vertical direction, the dispersion in the horizontal direction. The mechanism achieves the purposes of simplifying the structure, reducing the weight and reducing the manufacturing cost, and has the characteristics of novel, reasonable and simple structure, light weight of the mechanism, low manufacturing cost, smooth and stable operation, good operation quality, high efficiency and reliable use.

Detailed Description

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The utility model provides a miscellaneous ware throwing ware in maize picker cleaning plant, it mainly comprises spare parts such as upper boom 1, lower jib 2, frame 3, lower round hole sieve 4, upper round hole sieve 5, miscellaneous ware throwing ware poking roller 6, miscellaneous ware throwing ware thumb wheel 7, belt seat bearing 8, band pulley A9, connecting rod A10, connecting rod B11, drive belt 12, band pulley B13, crank 14, its characterized in that: the upper circular hole sieve 5 is fixedly connected with the frame 3 of the cleaning device through the upper suspender 1, and the lower circular hole sieve 4 is fixedly connected with the frame 3 of the cleaning device through the lower suspender 2. One end of a connecting rod A10 is hinged with an upper round hole sieve 5, the other end of a connecting rod A10 is hinged with a lower round hole sieve 4, one end of a connecting rod B11 is hinged with a crank 14, the other end of the connecting rod B11 is hinged with the upper round hole sieve 5 to form a crank-connecting rod mechanism, a sundry throwing device poking roller 6 is sleeved at the front end of a cleaning device rack 3 through a bearing with a seat 8, is fixedly connected with the cleaning device rack 3 and is positioned at the upper side of the upper round hole sieve 5, sundry throwing device poking fingers 7 are orderly arranged on the sundry throwing poking roller 6 according to a certain rule, one end of the sundry throwing device poking roller 6 is provided with a belt wheel A9, the same side end of the crank 14 is provided with a belt wheel B13, and the belt wheel A9 is connected with the belt wheel B13 through a transmission belt 12, so that the sundr.

During operation, the sundries throwing device drives a sundries throwing device poking roller 6 to work through a transmission belt 12 by a three-phase asynchronous direct current motor (not shown in the figure), a sundries throwing device poking finger 7 is fixedly connected with the sundries throwing device poking roller 6, and throwing work of corn threshing material particles falling from a shaking plate (not shown in the figure) is completed by rotary circular motion, so that the seed and the sundries are layered in the vertical direction and dispersed in the horizontal direction, accumulation of materials at an inlet is reduced, and the corn threshing material is thrown to the rear part of a sorting device vibrating screen. The cross-flow fan (not shown in the figure) is arranged in front of and below the cleaning device vibrating screen, and the airflow field generated by the cross-flow fan (not shown in the figure) blows away the corn threshed particles. The crank 14 is driven by a three-phase asynchronous direct current motor (not shown in the figure) to work through a transmission belt 12, so that the upper circular hole sieve 5 and the lower circular hole sieve 4 do periodic reciprocating motion to clean corn threshed particles, corn grains and small impurities leak from sieve pores of the vibrating sieve in the process of moving backwards, and the threshed particles are screened.
