Tipping operation mechanism for unloading barrel

Abstract

The invention discloses a tipping operation mechanism for an unloading barrel. The tipping operation mechanism comprises a first hinged support, a transverse hinge shaft, an operation block and a longitudinal operation device, wherein the transverse hinge shaft is hinged to the first hinged support, the operation block is fixed on the transverse hinge shaft and used for being hinged to a valve core bar of a hydraulic valve, and the longitudinal operation device is used for driving the transverse hinge shaft to rotate so as to enable the operation block to drive the valve core bar of the hydraulic valve to act. The tipping operation mechanism is simple in structure and very convenient to operate, and conforms to the human engineering. An operation handle is far away from an operation platform, space of legs of an operator is not occupied, operation is facilitated due to the fact that the operation handle is placed on the left side of the operator, labor intensity of workers is relieved, and working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of harvesters, and more specifically relates to a tilting operation mechanism for a grain unloading cylinder. [0002] Background technique [0003] During the harvesting process of the harvester, when the grain in the grain barrel reaches a certain amount, it needs to be unloaded to make room for continued harvesting. The authorized announcement number is CN 202455835 U, and the authorized announcement date is October 3, 2012 The Chinese invention patent discloses the hydraulic grain unloading device of the combine harvester. During the grain unloading process of the harvester, the grain cylinder is tilted through the operation of the hydraulic valve first, and then the next step is performed to unload the grain cylinder, but , Now in the process of operating the hydraulic valve, it is found that the hydraulic valve is installed under the console, and the operating handle is directly connected to the spool ...

[0002] During the harvesting process of the harvester, when the grain in the grain barrel reaches a certain amount, it needs to be unloaded to make room for continued harvesting. Authorized announcement number CN 202455835 U, the Chinese invention patent dated October 3, 2012, discloses the hydraulic grain unloading device of the combine harvester, and in the grain unloading process of the harvester, the grain cylinder is tilted through the operation of the hydraulic valve first, and then Carry out the next step to unload the grain cylinder. However, in the process of operating the hydraulic valve, it is found that the hydraulic valve is installed under the console, and the operating handle is directly connected to the valve core rod of the hydraulic valve. , the handle is located outside the operating table, and this position is the position of the human leg, which not only makes the placement of the leg uncomfortable, but also, when working, the operating handle is not convenient enough, and it is easy to touch the leg
