Description

An automatic preparation and spraying system of insecticide and disinfectant

technical field

The invention relates to the field of insecticide and insect repellent in the storage process of tobacco leaves, in particular to an automatic preparation and spraying system of insecticide and disinfectant.

Background technique

In gardens, farmland, hotels, farmhouses, tobacco storage rooms and other places, when spraying for disinfection or insecticide, it is necessary to prepare the liquid medicine before spraying. After the liquid medicine is sprayed, there will usually be a part of it remaining. If the remaining liquid medicine is left for a period of time before use, the efficacy of the medicine will decrease, and if it is directly poured out, it will pollute the environment.

During artificial spraying, people are in the spraying place and are likely to come into contact with the liquid medicine, or the liquid medicine is sprayed on the body, causing harm to the body.

Patent document CN 203226256 U discloses a kind of tobacco leaves insecticidal gas injection device, when the device is in use, solid insecticide such as solid aluminum phosphide (ALP) tablets are placed on the mesh support, start the water spray pipeline, and start to Sprinkle water in the reaction tank, aluminum phosphide (ALP) tablets react with water to produce phosphine (PH3) gas, control the relevant parameters of the aeration fan and flowmeter in the control system, and quantitatively inject it into the unit tobacco leaf insecticidal device Release insecticide gas. After putting in, dismantle the connection of the air-inflating pipeline and the air-intake pipeline of the unitary tobacco leaf desinsection device. After completing the entire insecticidal work, connect the exhaust pipeline on the airtight container of the unitary tobacco leaf insecticidal device with the exhaust pipeline of the exhaust system of the utility model, start the exhaust fan, and put the airtight container of the unitary tobacco leaf insecticidal device The remaining phosphine (PH3) in the tank is recycled to the reaction tank. Excess water in the reaction tank is discharged along the outlet pipe.

In the process of preparing insecticidal gas, putting it in, and finishing the treatment, manual assistance is required. When people come into contact with the pipeline, they are easy to come into contact with the insecticidal gas, which is likely to cause harm to the human body. The excess water in the reaction tank is discharged along the outlet pipeline. The water is mixed with solid pesticide residues, and its efficacy has been reduced. The water can no longer be used as a chemical agent and will cause pollution after discharge.

Patent document CN206549515U discloses a pesticide mixing device, which is provided with a long-necked funnel as a feed hopper, which is convenient for pouring medicines into. When dispensing, water is first injected and submerged in the lower end of the feed hopper, and then the medicines are introduced, and the medicines are directly discharged from the water. Spreads out for easy stirring. The setting of the stirring shaft and the stirring rod is convenient for full stirring and avoids drug floating or sedimentation.

Although the device can realize convenient pouring of medicine and sufficient stirring, it cannot constantly detect the dosage of medicine and water, and needs to be weighed or calculated in advance. It is inconvenient to handle the same medicament remaining, causing waste and pollution.

The working principle of the present invention is as follows:

There are multiple liquid storage barrels 8, five of which are provided in this embodiment, and each liquid storage barrel is equipped with a preparation mechanism 1 communicating with it, and the preparation mechanism 1 inputs the absorbed liquid into the same liquid distribution chamber through the catheter 4 within.

First, inject different medicaments into the four liquid storage barrels respectively, inject water into the fifth liquid storage barrel, and the liquid extraction pump 10 absorbs the liquid from the liquid storage barrels and transports it through the catheter. At this time, the liquid inlet electric valve 6, Liquid injection electric valve 7 is all opened, medicinal liquid and water enter liquid inlet cavity 5, and the air in the conduit discharges into liquid distribution cavity 4, and is extracted out by spraying mechanism.

Close the liquid inlet electric valve 6, start the cam mechanism 54, when the cam 543 rotates, when the large end of the cam 543 exerts a force on the input part 5213, the pressing arm 521 swings clockwise with the rotating shaft 523 as the fulcrum, thereby pressing the rear arm 5211 downward, and pressing the rear arm 5211 downward. A plate is arranged above the part 511, and when the rear arm 5211 is pressed downward, the pressing part 5214 contacts the plate, and a pressing force is applied to the plate, and the left side part 513 and the right side part 514 of the chamber 51 shrink, and the liquid in the chamber 51 is squeezed out. pressure, and enter the liquid distribution chamber 4 through the liquid injection electric valve 7.

When the small head end of the cam 543 touches the input part 5213, the extrusion force is released, the left side face 513 and the right side face 514 return to their original shapes, the liquid injection electric valve 7 is closed, the liquid inlet electric valve 6 is opened, and the liquid medicine and water are refilled. Enter the liquid inlet chamber 5. Therefore, through the elastic deformation of the chamber 51, suction and discharge of the liquid medicine and water are realized.

The liquid medicine and water enter the liquid distribution chamber 4. Since the cam 543 drives the chamber 51 to realize elastic deformation, the liquid in the chamber 51 enters and ejects in a continuous pulse state. When the liquid is sprayed into the liquid distribution chamber 4, its impact The force is convenient for the impact mixing between different medicinal liquids and water. The mixed liquid formed by one pulse is temporarily stored in the liquid distribution chamber 4 and then sprayed out by the spraying mechanism, so that residues are not easy to appear in the liquid distribution chamber 4.

The liquid level sensor 14 on the outer wall of the liquid storage barrel 8 detects the liquid storage situation in the barrel. When the liquid level in any liquid storage barrel is lower than the detection position, the liquid level sensor works, and the liquid storage barrel and its connected The configuration mechanism stops working, and the information is fed back to the control system, prompting the operator to forget to add the corresponding liquid in the liquid storage tank. This setting is also convenient for selecting several liquid storage barrels for liquid dosing as required.

The system can be used in different spraying places such as gardens, farmlands, hotels, farmhouses, and tobacco storage rooms. According to the size of the spraying area, different specifications of the liquid inlet chamber and cam mechanism can be selected to achieve reasonable liquid intake and distribution. The spraying mechanism can also be selected according to the needs, and the power of the drug pump and the flow rate of the nozzle can be changed.
