Embodiment

[0017] Such as Figure 1 ~ Figure 2 As shown, a multi-link drive mechanism used on harvesters includes crank wheel 1, draft screen 18, cleaning screen 19, grain collector 20, connecting rod A2, rocker A3, connecting rod B4, connecting rod C5, rocker B6, rocker C7, connecting rod D8, connecting rod E9, rocking rod D10, rocking rod E11, connecting rod F12, rocking rod F13, connecting rod H14, rocking rod H15, rack 16 and long axis 17, Draft screen 18, cleaning screen 19 and grain collector 20 are arranged sequentially from top to bottom; crank wheel 1 is hingedly mounted on the frame 16, one end of connecting rod A2 is hingedly mounted on crank wheel 1, and the other end of connecting rod A2 One end is hinged with one end of the rocker A3, and the rocker A3 is fixedly connected with the long shaft 17, and the long shaft 17 is connected with the frame 16 through a bearing; the other end of the rocker A3 is hinged with one end of the connecting rod B4, and connected The other end...

Embodiment 1

[0022] The driving mechanism of the multi-link driving mechanism used on the harvester is composed of crank crank wheel 1, and the multi-link driving mechanism used on the harvester also includes connecting rod A2, rocking rod A3, connecting rod B4, connecting rod C5, rocking rod B6, rocking rod C7, connecting rod D8, connecting rod E9, rocking rod D10, rocking rod E11, connecting rod F12, rocking rod F13, connecting rod H14, rocking rod H15 / frame 16 and long axis 17. Except crank wheel 1, connecting rod A2, major axis 17, all the other components are in the cleaning chamber (comprising draft sieve 18, cleaning sieve 19, grain collecting device 20, which are draft sieve 18, cleaning sieve 19, grain collecting device 20 as a whole) the other side has a symmetrical distribution, figure 1 , figure 2 No longer numbered. Its specific structure is: the crank wheel 1 is hinged with the frame 16, the crank crank wheel 1 is hinged with the connecting rod A2, the connecting rod A2 is...

Embodiment 2

[0024] figure 1 , figure 2 It can be seen that the multi-link drive mechanism used on the harvester is composed of crank wheel 1, connecting rod A2, rocking bar A3, connecting rod B4, connecting rod C5, rocking bar B6, rocking bar C7, Connecting rod D8, connecting rod E9, rocking bar D10, rocking bar E11, connecting rod F12, rocking bar F13, connecting rod H14, rocking bar H15, frame 16 and major axis 17 constitute. Since the parts other than the major axis 17, the crank wheel 1 and the connecting rod A2 are symmetrical, they are not shown separately in the figure.

[0025] from figure 1 It can be seen that, except crank wheel 1 and connecting rod A2, long axis 17, all the other components are in the cleaning room (comprising draft sieve 18, cleaning sieve 19, grain collector 20, which are draft sieve 18, cleaning sieve 19. The grain collector 20 as a whole) has a symmetrical distribution on the other side, and the power on the other side comes from the rocker A3 and is tr...

Abstract

The invention discloses a multi-connecting-rod driving mechanism for a harvester. A straw walking sieve, a cleaning sieve and a grain collector are arranged successively from top to bottom. A crank wheel is installed on a rack in a hinging mode; a connecting rod A is installed on the crank wheel in a hinging mode and is hinged to a rocking bar A; the rocking bar A and a connecting rod B are hinged; the connecting rod B and a connecting rod C are hinged; the connecting rod C and a rocking bar are hinged; the connecting rod and a rocking bar B are hinged; the rocking bar B and a rocking bar C are hinged with the rack; and the connecting rod C is fixedly connected to the grain collector. The rocking bar A and a connecting rod D are hinged; the connecting rod D is hinged to a connecting rod E; the connecting rod E is fixed on the straw walking sieve and is hinged to a rocking bar D; the rocking bar D is hinged to a rocking bar E and the rack; and a rocking bar E is hinged to the rack; a connecting rod F is hinged to a rocking bar E; the connecting rod F and a rocking bar F are hinged; and the middle part of the rocking bar F is installed on the rack in a hinging mode. The multi-connecting-rod driving mechanism is driven by one crank wheel and also the power is provided for the straw walking sieve, the cleaning sieve and the grain collector.

Description

technical field [0001] The invention relates to the technical field of harvesters, in particular to a multi-link drive mechanism used on harvesters. Background technique [0002] The connecting rod drive mechanism is widely used in the technical field of harvester machinery. Harvesters use a large number of wind screen cleaning devices, and generally use a crank rocker drive mechanism to realize the reciprocating motion of the vibrating screen. The community harvester currently being developed needs to realize the reciprocating motion of two or more layers of screens and a grain collector, and requires the movement between the three to meet a certain relative relationship. If several groups of crank-rocker mechanisms are used to drive separately, the transmission system of the whole machine will be too complicated, and it is difficult to ensure the relative positional relationship among the three. In order to solve this problem, it is necessary to develop a mechanism that ...
