Binary hydraulic manifold system

摘要

A hydraulic fluid manifold system for a spreader, the spreader including at least one bin for holding dry bulk material for distribution to at least one conveyor associated with the bin for receiving the dry bulk material from the at least one bin and transporting the dry bulk material to at least one spinner associated with the spreader. The hydraulic fluid manifold system includes a single, unitary manifold including a variable speed fluid control circuit for setting a speed for the at least one conveyor and a variable speed fluid control circuit for the at least one spinner of a spreader system for setting a speed for the at least one spinner, the variable speed control circuit for the at least one conveyor including an on/off device for the at least one conveyor that allows when fluid flow through the variable speed conveyor circuit to the at least one conveyor is turned on that the at least one conveyor can automatically operate at a speed set for the at least one conveyor prior to fluid flow to the at least one conveyor having been turned off. Further, the spreader can include at least two conveyors, and the variable speed control circuit for the at least two conveyors can further include flow of hydraulic fluid through the variable speed conveyor circuit to be changed between in-parallel flow to a first and a second of the conveyors simultaneously and in-series flow where flow of fluid is sent to a first one of the conveyors and then sent from the first one of the conveyors to a second one of the two conveyors.

1. An hydraulic fluid manifold system for a spreader, the spreader including at least one bin for holding dry bulk material for distribution to at least one conveyor associated with the bin for receiving the dry bulk material from the at least one bin and transporting the dry bulk material to at least one spinner associated with the spreader, the hydraulic fluid manifold system comprising
a unitary block including a control circuit for the at least one conveyor and a control circuit for the at least one spinner, the control circuit for the at least one conveyor including a first inlet port to which a first inlet hydraulic fluid line can be connected for delivering hydraulic fluid to the conveyor control circuit and a first outlet port to which a first outlet hydraulic fluid line can be connected for delivering hydraulic fluid from the conveyor control circuit in the unitary block to an hydraulic motor for the at least one conveyor, the conveyor control circuit further including a conveyor control passageway in the unitary block connecting the first inlet port and the first outlet port together and allowing hydraulic fluid to pass from the first inlet port out through the first outlet port, the unitary block including a first bore, the first bore communicating with the conveyor control passageway, and a first control valve removably connected in the first bore conveyor and inserted into the conveyor control passageway to regulate the flow of hydraulic fluid through the conveyor control passageway to the hydraulic motor for the conveyor and a second bore, the second bore communicating with the conveyor control passageway, and an on/off valve removably connected in the second bore and inserted into the conveyor control passageway to turn flow of hydraulic fluid through the conveyor control passageway on or off, and the control circuit for the at least one spinner including a second inlet port to which a second inlet hydraulic fluid line can be connected for delivering hydraulic fluid to the spinner control circuit and a second outlet port to which a second outlet hydraulic fluid line can be connected for delivering hydraulic fluid from the spinner control circuit in the unitary block to a hydraulic motor for the at least one spinner, the spinner control circuit further including a spinner control passageway in the unitary block connecting the second inlet port and the second outlet port together and allowing hydraulic fluid to pass from the second inlet port out through the second outlet port, the unitary block including a third bore into, the third bore communicating with the spinner control passageway, and a second control value removably connected in the third bore and inserted into the spinner control passageway to regulate the flow of hydraulic fluid through the spinner control passageway and to the hydraulic motor for the at least one spinner.
