DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.

[0022] In the description of this specification, unless otherwise clearly defined, words such as "setting", "installation", and "connection" should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meaning of the above words in this utility model based on the specific content of the technical solution.

[0023] like Figure 1 and Figure 2 As shown, the pesticide sprayer includes: a walking assembly 10, a lifting assembly and a head 30, the lifting assembly is connected between the walking assembly 10 and the head 30, the head 30 is connected to the lower end of the lifting assembly, and the head 30 includes a spray head 34 arranged on a head housing 31. When spraying is required, the walking assembly 10 drives the head 30 to move to the target position by walking on the hanging rail, the lifting assembly moves to make the head 30 descend, and the liquid medicine is sprayed out through the spray head 34.

[0024] The lifting assembly includes a lifting motor 21, a winding wheel 22, a pull rope 23 and a scissors-type telescopic frame 24. The upper end of the scissors-type telescopic frame 24 is connected to the lower end of the walking shell 11 of the walking assembly 10, and the lower end is connected to the upper end of the head shell 31. The winding wheel 22 is transmission-connected to the output shaft of the lifting motor 21. One end of the pull rope 23 is wound around the winding wheel 22, and the other end is connected to the upper end of the head shell 31.

[0025] When the target position for spraying is reached, the lifting motor 21 drives the winding wheel 22 to rotate, the pull rope 23 is released, and the scissor-type telescopic frame 24 is extended by gravity to make the machine head 30 descend, and spraying is carried out after it is in place. After the spraying is completed, the lifting motor 21 is reversed, the pull rope 23 is wound onto the winding wheel 22, and the scissor-type telescopic frame 24 is retracted to a high position by the upward force.

[0026] like Figure 2As shown, a water supply pipe and an air supply pipe (not shown in the figure) connected to the spray head 34 are arranged in the head housing 31, and a water control valve 32 is arranged on the water supply pipe and an air control valve 33 is arranged on the air supply pipe. Specifically, the spray head 34 is an ultrasonic atomizing nozzle, and the air supply pipe inputs high-pressure gas, so that the liquid medicine collides with the vibrator at the outlet of the ultrasonic atomizing nozzle at a high speed, and turns into fine particles in the form of mist. The spray head 34 is arranged on the side of the head housing 31, and a blower 35 is arranged on the side of the head housing 31 below the spray head 34. The blower 35 can blow the fine particle mist liquid medicine to a farther distance, thereby effectively expanding the diffusion distance of the sprayed liquid medicine. The air supply pipe inputs high-pressure gas into the spray head 34, which can effectively avoid the spray head 34 from being blocked.

[0027] Spray heads 34 and blowers 35 are respectively arranged on the sides of the machine head 30 in the forward direction. The hanging rail is installed in the middle of the greenhouse. The two spray heads 34 can spray the crops on both sides respectively. The air volume of the blowers 35 can be controlled to adjust the distance of the mist liquid. There are two water supply pipes and two air supply pipes, which are respectively connected to the spray heads 34 on both sides. The two water supply pipes are provided with water control valves 32, and the two air supply pipes are provided with air control valves 33, that is, the spray on both sides is controlled by two sets of control valves. The spray can be sprayed on both sides at the same time or in turns. In this design, a blower 35 is arranged on one side of the machine head 30, and spray heads 34 are arranged on the upper and lower sides of the blowers 35 on both sides.

[0028] like Figure 3 As shown, the travel assembly 10 includes a travel motor 12 arranged in a travel housing 11 and a travel wheel 13 installed on a hanging rail. The travel wheel 13 is transmission-connected to the output shaft of the travel motor 12. The travel motor 12 drives the travel wheel 13 to rotate to achieve movement on the hanging rail.

[0029] The moving housing 11 is provided with a sensing probe 14 for sensing the position mark on the hanging rail. When the sensing probe 14 detects the position mark, the target position for spraying is reached, the lifting motor 21 is activated, and after the machine head 30 is lowered to a suitable height, the water control valve 32, the air control valve 33 and the air blower 35 start to operate, and the spray head 34 starts spraying. The sensing probe 14 can have multiple implementation methods for locating the target position for spraying. Specifically, in this implementation, the sensing probe 14 is a magnetic induction switch, and the position mark is a magnet set on the hanging rail, which is not easily damaged and has a long service life.

[0030] The pesticide sprayer of the utility model is provided with a walking component, a lifting component and a machine head. The lifting component includes a lifting motor, a roller, a pull rope and a scissor-type telescopic frame. The lifting motor drives the roller to rotate and roll up or release the pull rope to realize the lifting and lowering of the machine head. The operator can adjust the spray height according to the height of the crops. The scissor-type telescopic frame can cooperate with the pull rope to extend and retract to support the pull rope and the machine head. The structure is stable and can ensure the stability of the machine head during the lifting process. The structure of the scissor-type telescopic frame enables a long descending distance, light weight, simple structure, not easy to be damaged, and long service life.

[0031] Although the specific implementation methods of the utility model are described above, those skilled in the art should understand that the described embodiments are only part of the implementation methods of the utility model, rather than all the implementation methods, which are only examples, and the protection scope of the utility model is defined by the claims. Those skilled in the art can make various changes or modifications to these implementation methods without departing from the principle and essence of the utility model and without any creative work, but these changes and modifications fall within the protection scope of the utility model.
