[0002] Pesticide spraying has been the biggest problem of greenhouse planting, and various pesticide spraying machines that replace manual work have appeared, but there is still a big gap from the goal of being economical and convenient. In recent years, with the popularization and use of various suspending aids, it has become possible to use a spraying machine to perform atomization work on one side of the greenhouse, and then use a fan to blow the mist into the interior of the greenhouse to kill insects and cure diseases.

[0003] Chinese utility model patent CN214629373U discloses a self-propelled spraying machine that can spray while walking on one side of the greenhouse, and during this period, the spraying is blown to the entire greenhouse by a fan, which is convenient to use and saves labor. However, the pesticide spraying machine has the following problems:

[0004] In order to facilitate towing and transfer, a transfer wheel is arranged on the walking frame, and when transfer is needed, it can be towed like a small trailer. During spraying operation, although the transfer wheel is higher than the track wheel and does not rub against the ground, the width of the transfer wheel generally exceeds the main body of the pesticide spraying machine, and in individual cases, it is easy to interfere with the debris on both sides of the track during operation, and optimization design is needed to avoid conflict with the components on both sides of the track.

[0005] In addition, during walking operation of the pesticide spraying machine, a simple track of the existing transport vehicle in the greenhouse is usually used, and there is no need to consider the problem of directional control when driving on such a track. However, due to differences in construction period and load design, the track gauge of the greenhouse track differs greatly (20 cm to 50 cm), and the tracks on both sides are not level, which makes it difficult for the pesticide spraying machine to adapt to different tracks. SUMMARY

[0006] Therefore, the technical problem to be solved by the utility model is to provide a spraying and pesticide spraying machine that can be easily towed during transfer and the transfer wheel shaft can be easily removed during spraying operation to avoid interference with the objects on both sides of the track, thereby improving the adaptability of the machine.
