  • Publication number: 20210386049
    Abstract: Provided is a chemical spraying device which can, even when a work vehicle travels on sloped work ground, rough roads or the like, spray a chemical onto crops onto which the chemical is to be sprayed, the spraying being performed without contact with the crops. A chemical spraying device capable of being mounted on a work vehicle is provided with: a chemical tank; chemical ejecting sections for ejecting a chemical supplied from the chemical tank; a plurality of first ejection support sections which have the chemical ejecting sections, extend in the top-bottom direction, and are oriented longitudinally; and a second ejection support section extending in the left-right direction from the chemical tank side and supporting the plurality of first ejection support sections. Each of the plurality of first ejection support sections is provided to be rockable about an axis extending in the front-rear direction relative to the second ejection support section.

  • Patent number: 4850536
    Abstract: A liquid ejection apparatus which is provided with a body thereof, a liquid ejector having a nozzle, and a liquid feed pipe, disposes an optical fiber along the liquid feed pipe, so that an optical signal is transmitted from a light emitting element to a light receiving element via the optical fiber. The liquid ejector is provided with a control unit for controlling transmission and cut off of the optical signal, thereby enabling remote control from the liquid ejector of operating equipments provided at the apparatus body.

  • Patent number: 4407640
    Abstract: A reciprocating pump, in which a pressure control valve has a pressure-receiving face and is supported to a valve seat bearing at least one of suction and discharge valves, the pressure-receiving face being disposed within a discharge passage, and at a cylinder head is provided a pressure adjuster for a control spring biasing the pressure control valve to the valve seat, so that the pressure control valve, which functions as a relief valve, safety valve or unloader valve, may be incorporated with a main body of the pump so as to simplify construction and decrease the number of parts, thereby making the pump less expensive to produce, smaller in size, and lighter in weight.
