Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse equipment, in particular to a pesticide spraying mechanism for a greenhouse. Background Art

[0002] Greenhouses were originally an important equipment for vegetable production. With the continuous improvement of people's living standards, the application of greenhouses has become more and more extensive. At this stage, greenhouses can also be used in flower cultivation, forestry seedling cultivation, fruit tree planting and other fields. During the entire planting process, in order to prevent various crops from being troubled by diseases and pests, it is necessary to regularly spray pesticides on the surface of crops. In order to improve the spraying efficiency of agriculture, at this stage, a spray system that can automatically spray liquid is generally installed on the top of the greenhouse. The spray system can move back and forth on the top beam of the greenhouse to spray pesticides. The sprinkler system is connected to a medicine dispensing box through a pipeline, and the mixed medicine in the medicine dispensing box is pumped to the sprinkler pipe by a medicine spray pump for uniform spraying. However, since the greenhouse generally occupies a large area, after the spraying work has been carried out for a period of time, due to the loss of medicine in the medicine dispensing box, it is necessary to add medicine and water to the medicine dispensing box again and mix them. The whole process requires the greenhouse manager to manually perform the mixing operation, which greatly increases the workload. In addition, it is difficult to ensure the accuracy of the amount of medicine added by manual dosing, which brings great inconvenience to greenhouse planting work. Utility Model Content

The dosing box 12 is also provided with a dosing controller for controlling the quantitative discharge of medicine.

[0018] The dosing controller includes a float 16 arranged in the dosing box 12, a float rod 17 is arranged on the upper end of the float 16, the top of the float rod 17 passes through the top of the dosing box 12 and extends to the outside thereof, and a sensor block 18 is arranged on the top of the float rod 17. The dosing controller also includes a mounting plate 19 arranged on the top of the dosing box 12, and a plurality of proximity switches 20 are evenly distributed on the mounting plate 19 in the vertical direction. The sensing end of the proximity switch 20 is arranged toward one side of the sensor block 18. The sensor block 18 cooperates with each proximity switch 20 to control the solenoid valve 15 to be closed. The dosing box 12 is also provided with a control switch for controlling the solenoid valve 15 to be opened.

[0019] When the control switch is turned on, the solenoid valve 15 will open, and the liquid medicine in the medicine adding box 12 will be transported to the inside of the medicine dispensing box 7 through the medicine outlet pipe 14 .

[0020] The proximity switches 20 are arranged equidistantly in the vertical direction, so as to ensure that the dosage of the medicine adding box 12 is the same each time.

[0021] A support frame 21 is provided on the top of the medicine dispensing box 7 , and the medicine adding box 12 is installed on the support frame 21 .

[0022] A motor 22 is provided on the top of the medicine dispensing box 7, and a driving shaft of the motor 22 is fixedly connected to the stirring shaft 10.

[0023] Support plates 23 are arranged on both sides of the top of the greenhouse body 1, a driving screw 24 is arranged on one side of the support plate 23, and the driving screw 24 is driven to rotate by a servo motor 25, and a guide rod 26 is arranged on the other side of the support plate 23, and a movable block 27 connected to the driving screw 24 and a slider 28 connected to the guide rod 26 are respectively arranged on both sides of the movable frame 2.

[0024] A supporting rib 29 is provided at the lower end of the supporting plate 23 .

[0025] The working principle of the utility model is as follows: first, the liquid medicine is filled into the medicine adding box 12. At this time, the float 16 floats on the surface of the medicine, and the induction block 18 on the top of the float rod 17 is located above all the proximity switches 20. Then, clean water is injected into the medicine dispensing box 7 through the water injection pipe 9, and then the medicine adding controller is turned on to allow the medicine adding box 12 to inject liquid medicine into the medicine dispensing box 7. With the injection of medicine, the liquid level in the medicine adding box 12 will gradually decrease. At the same time, the float 16 floating in the medicine adding box 12 will carry The floating rod 17 and the induction block 18 on its top gradually move downward. When the induction block 18 contacts the proximity switch 20 below it, the contact switch 20 will send a signal and control the electromagnetic valve 15 to close. At this time, the dosing box 12 stops adding medicine, and the amount of medicine added at this time is just adapted to the water in the medicine dispensing box 7, that is, it just meets the ratio requirement. Then the motor 22 starts and drives the stirring shaft 10 and the stirring blades 11 thereon to rotate, so as to evenly mix the medicine and water in the medicine dispensing box 7, and then the spray pump 3 starts The liquid medicine in the medicine dispensing box 7 is pumped out and sprayed through the spray pipe 4 below it. At the same time, the servo motor 25 is also started and controls the movable frame 2 to move back and forth in the greenhouse by driving the lead screw 24, and then drives the spray pipe 4 to spray the crops planted in the greenhouse. After the prepared liquid medicine in the medicine dispensing box 7 is used up, the staff can start the switch again, and then the medicine dispensing box 7 is filled with water, and then the medicine adding box 12 continues to inject medicine into the medicine dispensing box 7. As the liquid level in the medicine adding box 12 continues to drop, the sensor block 18 will move down again and continue to contact the proximity switch 20 below. At this time, the solenoid valve 15 will close and stop adding medicine, and the medicine dispensing box 7 will stir the liquid medicine again. In this alternating manner, the automatic proportioning and mixing of the liquid medicine can be achieved. The whole process does not require too much participation of the staff, which not only improves the efficiency of liquid medicine production, but also reduces the workload of the workers. In addition, the automatic dosing also reduces the error of the proportioning and ensures the efficacy of the medicine. All of these bring great convenience to the spraying work in the greenhouse.
