Apparatus and method for simultaneously topping and applying a precision application of sucker control chemicals to tobacco and other row crops
First Claim
1. An apparatus comprising a top area and a bottom area for simultaneously topping and precisely applying sucker control chemicals to tobacco plants and for related used, said apparatus comprising:
- (a) a housing comprising a front and a back with two sides and a top extending therebetween, said front and bottom of the housing being open for receiving tobacco plants as said apparatus is motivated co-linearly along a tobacco plant row;
(b) blower means positioned in the top area of said apparatus for creating a downwardly directed air stream;
(c) cutting means positioned in the bottom area of said apparatus in the air stream created by said blower means for mechanically decapitating tobacco plants as they enter said housing and pass therebeneath;
(d) a pair of spaced apart rotating belt means positioned beneath said cutting means and defining a pathway from the front to the back of said housing for gathering tobacco plants at the front of said housing and guiding the tobacco plants therethrough for simultaneous topping and precision application of sucker control chemicals;
(e) spray means for applying the sucker control chemical generally downwardly and in a confined pattern onto the decapitated tobacco plants as they pass from said cutting means and beneath said spray means; and
(f) circuit means comprising sensing means for determining the locations of tobacco plants that have been topped within the pathway of said pair of rotating belt means and for actuating application of the sucker control chemical through said spray means when the topped tobacco plants are properly oriented beneath said spray means.

Abstract
An apparatus for simultaneously topping and precisely applying sucker control chemicals to tobacco plants and for related uses wherein the apparatus comprises a housing wherein the front and bottom of the housing are open. A blower is positioned in the top of the apparatus for creating a downwardly directed air stream to facilitate decapitating the tobacco plants by a mechanical cutter positioned in the bottom of the apparatus as the tobacco plants pass therebeneath. A pair of spaced-apart rotating belts are located beneath the mechanical cutter and define a pathway from the front to the back of the housing and act to gather tobacco plants at the front and guide the tobacco plants through the housing. A spray manifold is provided for applying sucker control chemicals downwardly in a confined pattern onto decapitated tobacco plants as they pass from the mechanical cutter and beneath the spray manifold. Circuit means is provided for actuating application of the sucker control chemicals by the spray manifold when the tobacco plants are properly oriented substantially beneath the spray manifold.

11. An apparatus comprising a top area and a bottom area for simultaneously topping and precisely applying sucker control chemicals to tobacco plants and for related uses, said apparatus comprising:
-
(a) a housing comprising a front and a back with two sides and a tip extending therebetween, said front and bottom of the housing being open for receiving tobacco plants as said apparatus is motivated co-linearly along a tobacco plant; (b) blower means positioned in the top area of said apparatus for creating a downwardly directed air stream; (c) cutting means positioned in the bottom area of said apparatus on the air stream created by said blower means for mechanically decapitating tobacco plants as they enter said housing and pass therebeneath; (d) a pair of hydraulically driven spaced-apart rotating belts positioned beneath said cutting means and defining a pathway from the front to the back of said housing for gathering tobacco plants at the front of said housing and guiding the tobacco plants therethrough for simultaneous topping and precision application of sucker control chemical; (e) a spray manifold for applying the sucker control chemical generally downwardly and in a confined pattern onto the decapitated tobacco plants as they pass from aid cutting means and beneath said spray manifold; (f) circuit means comprising sensing means for determining the location of tobacco plants that have been topped within the pathway of said pair of rotating belts and for actuating application of the sucker control chemical through said spray manifold when the topped tobacco plants are properly oriented beneath said spray manifold; and (g) belt control means for maintaining the horizontal surface speed of said pair of hydraulically driven rotating belts at substantially the ground speed of said apparatus. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
