Description

Technical Field

[0001] The utility model relates to the technical field of pesticide sprayers, in particular to a track-type pesticide sprayer host. Background Art

[0002] When crops are infected with pests and diseases, the first choice of treatment measure is to spray pesticides. For large-scale crops or forests, mechanized spraying is used to improve efficiency. However, when spraying pesticides on crops in greenhouses, large-scale mechanized equipment cannot be used. In this case, manual spraying is usually used. However, when spraying pesticides in this way, the hands come into contact with these pesticides for a long time, which can cause certain irritation to the skin and is not good for health. In addition, manual spraying is slow and cannot be used for large-scale spraying. The work efficiency is low and the work intensity is high.

[0003] After searching, patent number CN202110511382.4 discloses an automatic sterilization and fertilization machine for agricultural planting, including a main unit, an automatic wire take-up device installed at the bottom of the main unit, and a medicine storage device fixedly connected to one side of the main unit, wherein: the main unit includes a shell, and the inner bottom of the shell is sequentially provided with two fan chambers, two diaphragm pumps and a main controller, and the outer wall of the shell is fixedly provided with four water pipe interfaces, five nozzles, left and right water pump speed regulators, branch water pump speed regulators, position Hall sensors and aviation sockets. The main controller, fan chamber, diaphragm pump, left and right water pump speed regulators, branch water pump speed regulators, position Hall sensors and aviation sockets are electrically connected. The water pipe interface is connected to the input end of the diaphragm pump through a connecting pipe, and the output end of the diaphragm pump is connected to the input end of the fan chamber through a connecting pipe. The nozzle passes through the shell and is installed on the fan chamber. A walking device is installed on the top of the shell, and a travel switch is installed on the top of the shell, and the travel switch is electrically connected to the main controller.

[0004] Although the above-mentioned automatic sterilization and fertilizer applicator can spray pesticides or fertilizers on crops or fruit trees in the greenhouse by combining the main unit and the medicine storage device into a whole and using the walking device installed on the main unit to make the machine move on the track, thereby solving the technical problem that large-scale spraying equipment cannot spray pesticides on crops in the greenhouse, there are still some things that have not been considered in actual use. For example, when the main unit moves on the track, the spraying angle can only be adjusted according to the direction of the track, and the spraying angle cannot be adjusted independently, resulting in unsatisfactory spraying effect.

[0005] Therefore, a track-type pesticide sprayer host is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a track-type pesticide sprayer host to solve the above-mentioned technical problems.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a rail-type pesticide sprayer main unit, comprising a main unit housing, an action component fixedly mounted on the top of the main unit housing, a fan chamber rotatably mounted inside the main unit housing, a bracket fixedly mounted on the top of the fan chamber, a motor fixedly mounted on the surface of the bracket, the output shaft of the motor passes through the bracket and is fixedly mounted with a swing arm, a rocker is rotatably mounted on the end of the swing arm away from the motor, a suspension is rotatably mounted on the end of the rocker away from the swing arm, the suspension is fixedly mounted on the surface of the main unit housing, and a bearing is fixed between the suspension and the bracket.

[0008] Preferably, the main body housing is composed of side panels, a top panel and a front panel, the fan chamber is rotatably installed between the two side panels, and the suspension is fixedly installed on the surface of the side panels.

[0009] Preferably, a plurality of nozzles are provided at the front end of the fan chamber, and the nozzles are composed of a nozzle body and a Laval nozzle. The outer surface of the rear portion of the Laval nozzle is spherical, and the rear portion of the Laval nozzle is rotatably sleeved on the inner wall of the nozzle body. The inner end of the Laval nozzle is also spherical, and contracts toward the nozzle outlet of the nozzle body and then expands to the nozzle outlet of the nozzle body. A liquid spray outlet is fixedly provided in the middle part of the Laval nozzle, and a liquid supply pipe is connected to the rear end of the liquid spray outlet, and a block is fixedly installed at the front end of the liquid spray outlet.

[0010] Preferably, the number of the plurality of nozzles includes but is not limited to eight, and the plurality of nozzles are equidistantly distributed at the front end of the fan chamber.

[0011] Compared with related technologies, the track-type pesticide sprayer provided by the present invention has the following beneficial effects:

[0012] The utility model provides a track-type sprayer main unit, in which the action component is connected to the erected track to drive the sprayer to move, and then the motor is started so that its output shaft drives the swing arm to rotate. In addition, because the rocker arm and the suspension rotate at a fixed point, and the bearing fixed between the bracket and the suspension can act as a fulcrum, the fan chamber can swing left and right when spraying, and there is no need to rely on the track to change the spraying angle, thereby effectively increasing the spraying range and improving the spraying efficiency.

[0013] The utility model provides a track-type pesticide sprayer main unit. When the pesticide sprayer is turned on and in operation, liquid medicine is injected into a fan chamber, enters through a port A of a liquid spray port, and is then sprayed onto a block for collision and atomization, thereby forming liquid medicine mist. At the same time, air is blown by the fan chamber, and the air flow is accelerated through a port B of each Laval nozzle, and is further accelerated through an expansion port, and is sprayed out evenly and at a high speed with the liquid medicine mist, thereby further improving the spraying efficiency of the liquid medicine.
