Embodiment Construction

[0020] An example of a corn harvester is Figure 1~2 Shown: It includes the main frame and the corn harvesting device, peeling machine and grain removal and screening device set on it. The grain removal and screening device includes the screening device frame and the sieve body 6 extending forward and backward in the length direction. The sieve body 6 passes through the movement The mechanism and follow-up mechanism can produce front and rear movement and up and down movement and are assembled on the frame of the screening device. The movement mechanism and follow-up mechanism are arranged at the front and rear ends of the screen body at intervals along the front and rear directions. The movement mechanism and follow-up mechanism are separately located in The upper and lower sides of the sieve body. The motion mechanism includes a drive shaft 1 set on the frame, the rotation axis extends in the left and right directions and is driven by a corresponding power source. The drive ...

Abstract

The invention relates to a corn harvester and an edulcoration and screening device for grains of the corn harvester. The edulcoration and screening device for grains of the corn harvester comprises a machine frame and a screen body with the length direction extending in the front and the back. A following mechanism and a moving mechanism are arranged on the machine frame in the front and the back directions at intervals. The moving mechanism comprises a planer connection rod transmission mechanism and a driving shaft arranged on the machine frame. The planer connection rod transmission mechanism comprises a driving arm and an eccentric block, wherein the driving arm is fixedly arranged on the driving shaft, the length of the driving arm extends in the radial direction of the driving shaft, the eccentric block is provided with two hinged positions with the radial directions respectively extending in the lateral direction, one hinged position of the eccentric block is connected with the screen body in hinged mode, a connection rod is hinged to the other hinged position of the eccentric block, and one end of the connection rod far away from the eccentric block is connected with one end of the driving arm far away from the driving shaft so as to lead the eccentric block to drive the screen body to be in forward slanting and backward slanting reciprocating motion when the driving shaft circumferentially rotates. The edulcoration and screening device for grains of the corn harvester solves the problem in the prior art that the screen body cannot screen grains in vibration mode.

Description

technical field [0001] The invention relates to a corn harvester and a seed impurity removal and screening device thereof. Background technique [0002] The existing corn harvester mainly includes a corn harvesting device, a peeling machine and a grain removal and screening device. The grain removal and screening device mainly transports and discharges the corn husks stripped off by the peeler and the removed broken stems through a chain rake. The husk leaves, broken stems and a small amount of grains falling off from the peeling machine fall on the cleaning sieve through the sieve body of the grain removal and screening device, and the corn husk leaves and broken stalks are transported to the remote end by the corresponding conveyor chain target until Discharged from the outside of the corn harvester, the grains are gradually discharged from the bracts and broken stems with the rotation of the conveyor chain target, and then fall through the sieve body and the cleaning siev...
