Abstract

Abstract Traction equipment of limited height capable of traveling between rows of plants and under the lowermost overlapping branches of the plants in the adjacent rows carries or pulls a dispensing device also of limited height to spray under pressure a suitable substance for the treatment of the plants under sufficient pressure to reach the trunk and foliage of said plants, guiding means are provided so as to feel the opposite plants or the sides of the furrow or ditch therebetween so as to cause the turning of the wheels of the traction apparatus so as to follow the direction of the furrow or the ditch. The device has a suitable pump and conduits which are valve controlled, and has suitable servo motors for operating the driving mechanism at a desired speed and also for operating the pump and controlling the valve for the spraying liquid. Remote control devices such as selected tone transmitter from control tone generators and suitable actuating tone receiver on the tractor and the apparatus, may be provided to permit the operation of the device from a remote location such as a tower overlooking the entire field on which the rows of plants are located.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 144 words
Means for dispensing a treating substance to rows of low growing plants forming a relatively low tunnel above a furrow, comprising a traction vehicle of a height and width less than the height and width of said low tunnel, propelling means on said traction vehicle to propel the same through said tunnel, dispensing means of dimensions less than the dimension of said tunnel for dispensing said treating substance under pressure toward the plants about said tunnel, electrically actuated means for controlling said propelling means on said vehicle, being adapted to be controlled remotely, electrically actuated means for controlling said dispensing means, being adapted to be operated by remote control, remote control means to transmit electrical actuation to the respective electrically actuated meaNs at will, said dispensing means including spraying means directing sprays laterally and upwardly to the plants along opposite sides of said furrow.
Claim 2
Dependent Claim 144 words
Means for dispensing a treating substance to rows of low growing plants forming a relatively low tunnel above a furrow, comprising a traction vehicle of a height and width less than the height and width of said low tunnel, propelling means on said traction vehicle to propel the same through said tunnel, dispensing means of dimensions less than the dimension of said tunnel for dispensing said treating substance under pressure toward the plants about said tunnel, electrically actuated means for controlling said propelling means on said vehicle, being adapted to be controlled remotely, electrically actuated means for controlling said dispensing means, being adapted to be operated by remote control, remote control means to transmit electrical actuation to the respective electrically actuated meaNs at will, said dispensing means including spraying means directing sprays laterally and upwardly to the plants along opposite sides of said furrow.
Claim 3
Dependent Claim 36 words
The invention specified in claim 1, and means on said traction vehicle coacting with the sides of said tunnel and the banks of said furrow for steering said traction vehicle along said furrow and said tunnel.
Claim 4
Dependent Claim 58 words
The invention specified in claim 2, and said steering means including, at least one pivoted castored wheel on said traction vehicle, and feeler extensions connected to said wheel so as to turn said wheel when said extension contacts a plant or a side of said furrow so as to turn said wheel toward the middle of said furrow.
Claim 5
Dependent Claim 26 words
The invention specified in claim 3, and said extension extending to a distance at least equal to the length of said traction vehicle and dispenser means.
Claim 6
Dependent Claim 31 words
The invention specified in claim 4, and said traction vehicle and said dispenser being elongated to a length several times the width of the space between the adjacent rows of plants.
Claim 7
Dependent Claim 39 words
The invention specified in claim 5, and abutment means extended forward from said traction vehicle inclined upwardly and forward to raise said traction vehicle when abutting an obstruction thereby to aid said traction vehicle to ride over said obstacle.
Claim 8
Dependent Claim 62 words
The invention specified in claim 1, and each of said electrically actuated means including a servo motor, a servo switch for each servo motor, said remote control means including tone generators of different frequencies, receivers at the switches tuned to the respective tone generators, and circuit closing means for the respective tone generators selectively operable for actuation of the respective servo motors.
