Bi-directional piston double row type high efficiency pump device for agricultural chemical sprayer

Abstract

The present invention relates to a bi-directional piston double-line type high efficiency pump device for an agricultural chemical sprayer, in which a pumping operation by means of a piston is conducted in a bi-directional double row when agricultural chemicals are sprayed, thereby maximizing efficiency. In addition, the device can be easily manufactured and assembled, and the device enables a high performance pumping operation at a lower cost. Specifically, the present invention is configured as follows: a shaft installation space part (110) is formed in the inner center of a housing body (100), both sides of which are formed to INC.lude pumping operation chambers (120), and a plurality of cylinder communication grooves are formed in each of the pumping operation chambers (120) at the right and left sides; a plurality of eccentric cam wheels (210) are formed in a multi-stage manner at a rotation shaft (200) installed in the shaft installation space part (100) of the housing body (100); upper and lower link units (300) having rod connection parts (330) of different directions are coupled in each of the cam wheels (210); the rod connection parts (330) each comprise a piston rod (400) and a piston (410); and a cylinder fixing unit (500), a pumping cylinder (700) and a cylinder cap unit (600) are assembled and coupled by means of a batch fixing means (800) outside the pumping operation chambers (120) at the right and left sides of the housing body (100), in which a plurality of pumping operation chambers (120) are formed.

Description

technical field [0001] The invention belongs to the technical field of agricultural pesticide application machinery, and in particular relates to a two-way piston high-efficiency pump for a pesticide sprayer which adopts a two-way piston reheating method to improve efficiency, simplify structure and reduce cost when spraying pesticides. Background technique [0002] At present, in agricultural sprayers, various pump devices are often installed to form and use. However, most of the pump devices have complex structures, low pumping (transportation by pump) efficiency, and frequent failures. Moreover, the cost is high, not only is there a problem of poor economy, but also a high-power motor and a large amount of electricity are required when it is put into operation, and a cylinder and a piston are also used. The pump device with these configurations also becomes very large in weight and volume , so there is also the problem of high energy consumption. [0003] There has been ...
