Abstract: A low cost sprayer and method of using the sprayer is disclosed. The sprayer is formed with a length of flexible tubing having an inlet end and a tubing outlet end. A nozzle is secured to the outlet end of the hose in a manner to provide a predetermined flow pattern upon rotation of the tubing and nozzle. In use, the inlet end of the tubing is placed within an agricultural chemical containing tank and a predetermined length of the remainder of the tubing is rotated by a worker as he walks through the area to be sprayed. By varying the radius of the rotating portion of the tubing and by varying the type of spray nozzle employed, the swath width and the droplet size of liquid chemical application can be closely controlled. Granular agricultural chemicals can be applied by rotating a granular material nozzle about its axis while rotating the tubing in a vertical plane.

Abstract: Equipment for delivering fluids such as herbicides comprises a handset which supports delivery means such as a spraying head on a support tube 4. The handset receives a container 134 of fluid which is to be distributed, this container being received within a cavity 132 in the handset. The container is retained within the cavity 132 by latching elements 166 provided on a pivotable lever 162. As the container 134 is inserted into the cavity 132, the container engages a cam 168 which causes the lever 162 to pivot into the engaged position. An outlet fitting 150 provided on the container is automatically engaged with an inlet fitting communicating with a supply duct 10 for supplying fluid from the container to the spraying head.

Abstract: A self-powered spraying device for dispensing a metered amount or a continuous amount of chemical. A valve is connected through conduits to a cavity in front of a piston, to a cavity in the rear of the piston, to a fluid pressure source and to a nozzle. In the open position of the valve the rear cavity is connected to the fluid pressure source, and the front cavity to the nozzle. In the closed position of the valve the front and rear cavities are connected so that a spring within the front cavity drives the piston to the rear, thereby transferring chemical from the rear cavity to the front cavity. A second valve is also provided which in an opened position permits the metered dispensing of chemical when the first valve is operated and when in a closed position permits the continuous release of chemical when the first valve is operated.
Abstract translation: 用于分配计量或连续量化学品的自动喷涂装置。 阀通过管道连接到活塞前面的空腔，活塞后部的空腔，流体压力源和喷嘴。 在阀的打开位置，后腔连接到流体压力源，并将前腔连接到喷嘴。 在阀的关闭位置，前腔和后空腔被连接，使得前腔内的弹簧将活塞驱动到后部，从而将化学物质从后腔转移到前腔。 还提供了第二阀，当打开第一阀被操作时，在打开位置允许计量分配化学品，并且当处于关闭位置时允许在第一阀操作时连续释放化学品。

Abstract: Equipment for spraying a fluid such as a herbicide comprises a support tube on which is mounted a head comprising a body and a rotatable disc. Electrical supply leads and a supply hose for fluid pass to the head through the support tube. The head and the body define between them a narrow annular gap. Fluid is supplied to the disc at a position radially inwards of the gap and flows through the gap to be discharged as fine droplets form the periphery of the disc. The width of the gap is such that the fluid passing through it is wiped circumferentially so that it is distributed around the disc. This promotes an even spray of fluid from all parts of the periphery of the disc. Special shapes for the disc are proposed in order to promote the formation of small droplets of uniform size.
Abstract translation: 用于喷洒诸如除草剂的流体的设备包括支撑管，其上安装有包括主体和可旋转盘的头部。 电源引线和用于流体的供应软管通过支撑管传递到头部。 头部和身体在它们之间形成狭窄的环形间隙。 流体在间隙的径向向内的位置处供应到盘，并且流过间隙，以微小的液滴形成盘的周边。 间隙的宽度使得通过它的流体周向擦拭，使得其分布在盘周围。 这促进了从盘的周边的所有部分均匀喷射的流体。 提出了用于盘的特殊形状以促进形成均匀尺寸的小液滴。
