Abstract
A series of wick ropes are pressure fed with herbicide. They are moved along weeds to be killed at about a 35.degree. angle so that the ropes wipe along the weeds applying herbicide thereto. Each rather short section of rope is fed by a different reservoir so that if the applicator is on a slope as by a roadside, the head upon the ropes at one end is not much greater than upon the other end.
Claims9
In a wet rope applicator for applying herbicides to weeds comprising in combination:
- a. a loose woven synthetic rope having two ends,
- b. one end of the rope telescoped in one tube and
- c. the other end of the rope telescoped in another tube,
- d. seal means on each of the tubes and rope for sealing the rope and tubes,
- e. supply means connected to each tube for supplying liquid herbicide under pressure to said tubes and thus pressure feeding said rope,
- f. a frame having
- (i) a front horizontal bar and
- (ii) a back horizontal bar,
- g. vehicle means on the frame for supporting and moving in an application direction said frame along the land to which the herbicide is to be applied,
- h. a series of pairs of first and second headers on the frame for carrying herbicide,
- i. a parallel group of said ropes, each of said ropes extending from one of said tubes in the first header to one of said tubes in said second header, of each pair,
- j. a series of double outlet reservoirs of liquid herbicide
- k. each of said double outlet reservoirs fluidly connected to a first and a second header of one of said pairs,
- l. mounting means on each of the reservoirs for mounting the reservoir at an adjustable distance above the headers to which it is connected.
