Power steering device for cultivator

Abstract

The invention provides a power steering device for a cultivator, which substitutes traditional long control stick and selectively transmits hydraulic pressure generated by the power of a cultivator totwo hydraulic cylinders arranged at two sides between a body and a trailer which are hinged with each other through a deflecting rod so as to easily operate direction of the cultivator. The power steering device comprises a hydraulic pump (10) used for generating hydraulic pressure by utilizing cultivator engine driving force, a hydraulic valve (20), a deflecting rod (30) and two hydraulic cylinders (40a and 40b), wherein the hydraulic pressure supplied by the hydraulic pump (10) flows into an inflow port (Pi), an outlet (Po) is connected a hydraulic pot (16) used for supplying hydraulic oilto the hydraulic pump (10), the hydraulic valve (20) is provided with a valve core (22) for converting the supuplying direction of the hydraulic oil flowing into the inflow port (Pi) to a first outlet(P1) and a second outlet (P2) for converting the cultivator direction, the deflecting rod (30) moves the valve core (22) forward or backward to adjust the hydraulic oil supply direction of the hydraulic valve (20), the two hydraulic cylinders (40a and 40b) are parallelly arranged at two sides between the cultivator body (1) and the trailer (2) hinged with the body (1) and respectively connected with the first outlet (P1) and the second outlet (P2) of the hydraulic valve (20) to adjust the cultivator direction, and a driving mat (50) is integratedlly and fixedly arranged at back of the cultivator body (1).

Description

technical field [0001] The present invention relates to a power steering device for a cultivator. In the prior cultivators, when driving on uneven roads or turning, the long and clumsy joystick used for steering often rotates rapidly, making it difficult for the driver to control and frequently causing accidents. When moving forward or backward, the direction adjustment is complicated and quite laborious. However, the cultivator power steering device of the present invention replaces the previous clumsy and long joystick, and utilizes the power of the cultivator to continuously generate hydraulic pressure, and utilizes the hydraulic pressure generated by easy operation. The steering rod selectively transmits the hydraulic pressure to the two hydraulic cylinders arranged on the left and right sides between the hinged cultivator body and the trailer, so as to easily operate the cultivator's driving direction. Background technique [0002] The cultivator is a must-have agricult...

Problems solved by technology

This is because many people only pay attention to the partial improvement of the cultivator when improving the cultivator, and even if the cultivator is improved, its structure tends to become more complicated, reducing its practicability, and it is difficult to actually promote it in rural areas
