Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and engineering machinery technology, and in particular to a novel pneumatic sprayer. Background Technology

[0002] A sprayer is an agricultural machine that disperses liquids; it's a type of agricultural pesticide application machinery. Pneumatic fogging machines produce very small droplets, and as is well known, smaller pesticide droplets result in better control. Multiple experiments have proven that fog has impenetrable penetration, capable of killing pests even in dense tree canopies and bark crevices. Smaller droplet diameters mean a greater number of droplets; experiments have shown that the more droplets per unit area, the better the control effect. A large number of droplets diffuse and are evenly distributed in space, greatly increasing the chance of contact with pathogens and pests, thus improving control efficacy. This advantage is particularly significant when used indoors (in greenhouses). Pneumatic sprayers not only produce even smaller droplets but also deliver pesticides over longer distances. However, for plants with many branches, existing pneumatic sprayers, when delivering pesticides from bottom to top, can only spray the pesticide to a fixed location, affecting the control effect.

[0043] In use, the tracked transport vehicle is disassembled and installed with a pneumatic spraying mechanism, enabling the tracked transport vehicle to perform multiple functions.

The spraying pump 59 delivers the pesticide liquid to the spraying valve 66 for spraying. The blower fan 63 rotates under the drive of the spraying engine 60.

The tracked transporter, by employing an improved range extender 3, can effectively reduce pollution from fuel emissions and lower the operating costs of agricultural machinery. Since existing range extenders 3 are unsuitable for agricultural machinery, the applicant has improved and upgraded the range extender 3 based on actual conditions. The rare-earth magnetic poles 18 of the rotor 13 and the coils of the stator 14 work together to achieve a speed increase of 3300-3600 rpm, thereby achieving a voltage output of 48-56V. The conventional 250W range extender motor 6 is upgraded to 2500W. The power between the stator 14 and the rotor 13... A heat dissipation component 22 can be installed on the output shaft 11. The heat dissipation component 22 can rotate and send the heat generated during power generation to the heat dissipation hole 17 of the flywheel 12, so as to prevent the applicant from modifying the generator 9 and blocking the heat dissipation hole 17, which would cause the motor 6 to overheat due to overload. The multi-functional setting of the functional seat 8 can realize the multi-functional requirements of the tracked transport vehicle. The functional seat 8 can be used as a hopper. When used as a hopper, the functional seat 8 can be flipped to unload materials. When supporting other functional equipment, the hopper side plate can be installed at the track 29 position, so that it can be installed again when the hopper is needed later.
