Spraying machine with function of automatic control over swing and steering

Abstract

The invention discloses a spraying machine with a function of automatic control over swing and steering. The spraying machine comprises a machine frame (1), a power source (2), a liquid storage box (3) and a liquid pump (4). The spraying machine is characterized in that a controller (5) and a stand column (6) are further installed on the machine frame (1), and an automatic swing and steering spraying device (7) is installed on the stand column (6). The automatic swing and steering spraying device comprises a reciprocating rotating support (71) installed on the stand column (6), wherein a swing mechanism (72), a steering mechanism (73) and a spray gun rocker arm (74) are arranged on the rotating support (71), an output shaft of the steering mechanism (73) is fixedly connected with one end of the stand column (6), and one end of the output shaft of the steering mechanism (73) is fixedly connected with the spray gun rocker arm (74). The controller (5) controls a spraying nozzle installed on the spray gun rocker arm (74) of the rotating support (71) to spray in all directions. According to the spraying machine, the up-and-down swing amplitude and the horizontal steering angle of a spray gun of the spraying machine can be controller as needed, the spraying machine is simple in structure and low in cost, and convenient to maintain and operate, spraying efficiency is improved, and a spraying operator can operate the spraying machine on a remote control keyboard in a remote mode, controls the spray gun to spray, and cannot be hurt by pesticide.

Description

technical field [0001] The invention relates to a sprayer, in particular to a sprayer with automatic swing and steering of a remote control spray gun, which belongs to the technical field of agricultural and forestry machinery. Background technique [0002] At present, the sprayer has been widely used in fields such as sprinkling irrigation and spraying pesticides, insecticides, bactericides, and disinfectants. The spraying equipment of the sprayer sprays the liquid to the target object through the spray gun. Generally, the sprayer includes a frame on which a generator set, a power distribution control device, a medicine box, a medicine liquid pump, and spraying parts of a medicine spraying system are arranged, and the liquid inlet of the medicine liquid pump is connected with the liquid outlet of the medicine box. , the liquid inlet of the nozzle in the spraying part of the spraying system is connected with the liquid outlet of the liquid medicine pump. The nozzle sprays o...

Problems solved by technology

However, the spraying system of this sprayer is electronically controlled, especially the stepper motor is used to control the nozzle swing, and its control system is complicated. Usually, the stepper motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. , it must be used by a control system composed of a double-ring pulse signal, a power drive circuit, etc.

Therefore, it is not easy to control the forward and reverse rotation of the stepping motor. It involves a lot of professional knowledge such as machinery, motors, electronics and computers. Its structure is complicated, the cost is high, and it is not easy to maintain.

Another Chinese invention patent authorization announcement number is CN101664724B, the name is: a self-propelled remote control sprayer (hereinafter referred to as "the latter patent"), the technical solution of the "second patent" is the technical solution of the "previous patent" The "later patent" specification pointed out the defects in the technical solution of the "previous patent". The defects are: the lifting control system and the spraying system of the self-propelled remote control sprayer are electronically controlled, and their structures are complicated. , high cost, and not easy to maintain

[0006] 3. Since the spraying direction of the nozzle of the machine is consistent with the position of the whole machine, that is, the spraying direction of the nozzle cannot be rotated left and right, and the spray gun can only swing up and down in a plane. If the nozzle needs to be turned horizontally, the frame of the sprayer must be adjusted Therefore, it is time-consuming and labor-intensive, which directly affects the spraying efficiency
