HYDRAULIC ALTERNATING SYSTEM FOR AGRICULTURAL BALER

摘要

A hydraulic circuit includes a control valve, a first hydraulic actuator, and a second hydraulic. The hydraulic circuit is configured such that in a first step, the first hydraulic actuator opens a product barrier in response to movement of the control valve into a first position, in a second step, the second hydraulic actuator moves a product engagement member in a first direction and the first hydraulic actuator closes the product barrier in response to movement of the control valve into a second position, in a third step, the first hydraulic actuator opens the product barrier in response to movement of the control valve into the first position, and in a fourth step, the second hydraulic actuator moves the product engagement member in a second direction and the first hydraulic actuator closes the product barrier in response to movement of the control valve into the second position.

1. A hydraulic circuit comprising:
a selective control valve actuatable between a first position and a second position; a first hydraulic actuator operable to open and close a product barrier; and a second hydraulic actuator operable to move a product engagement member, the hydraulic circuit configured such that in a first step, the first hydraulic actuator opens the product barrier and the second hydraulic actuator moves the product engagement member in a first direction in response to movement of the selective control valve into the first position; in a second step, the first hydraulic actuator closes the product barrier and the product engagement member remains in place in response to movement of the selective control valve into the second position; in a third step, the first hydraulic actuator opens the product barrier and the second hydraulic actuator moves the product engagement member in a second direction opposite the first direction in response to movement of the selective control valve into the first position; and in a fourth step, the first hydraulic actuator closes the product barrier and the product engagement member remains in place in response to movement of the selective control valve into the second position.
