Material conveying apparatus with functions of uniformly distributing material and performing self-excitation vibration

Abstract

The invention provides material conveying apparatus with the functions of uniformly distributing a material and performing self-excitation vibration. The apparatus includes a flexible shaking conveying device; the flexible shaking conveying device comprises a material shaking plate, three longitudinal exciting motors, two transverse motors, flexible shock-absorbing pads and a mounting base seat; the material shaking plate comprises a shaking plate surface, a left side plate, a right side plate, a rear side plate and a bottom plate; the three longitudinal exciting motors enable a material conveying plate to perform elliptical motion in a longitudinal plane through cooperation of an initial phase, a rotation direction and a rotation speed, and to push and throw the material; the two transverse motors can realize rectilinear motion of a throwing plate in the transverse direction through cooperation of an initial phase, a rotation direction and a rotation speed, and enable the material tobe uniformly and transversely distributed on the shaking plate; and the shaking plate is connected to a machine frame through the side plates equipped with the four flexible shock-absorbing pads. Theapparatus provided by the invention can reduce the complexity of power transmission of a harvester, automatically and uniformly distribute the material on the shaking plate, reduce the vibration effect of the shaking plate on the machine frame, reduce the noise and prolong the service life of the machine frame.

Description

technical field [0001] The invention belongs to the field of agricultural machinery research, and in particular relates to a material conveying device with uniform material distribution and self-exciting vibration functions. Background technique [0002] With the popularization of grain combine harvesters, in addition to ensuring the operation effect, the requirements for operation comfort are also getting higher and higher. Among them, machine vibration and noise have a great impact on the life of the machine and the physical and mental health of the operator. The material shaking plate of the traditional grain combine harvester is an eccentric mechanism, which increases the complexity of the transmission system. When the uneven protruding material falls from the vertical axial flow drum, it is necessary to install guide strips to evenly distribute the material on the shaking plate surface, and the uniform distribution effect is not ideal. For example, in Chinese patent CN...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that when the shaking plate adopts an eccentric mechanism, the transmission mechanism is complicated, the vibration and noise of the whole machine are caused, and the materials cannot be effectively evenly distributed
