[0030] As shown in Figure 4 , in order to further expand the installation height of the mist outlet 42 and make it adapt to more occasions, the mist outlet 42 can also be fixed at the middle position of the walking frame 1 through the support rod 43, at this time the support rod 43 is fixed transversely on the walking frame 1, so that the mist outlet 42 is fixed at the middle position of the walking frame 1 with adjustable transverse position.

[0031] As shown in Figure 1 and Figure 2 , the walking frame 1 is provided with a motor automatic start-stop device, the motor automatic start-stop device includes a travel switch 6 for obtaining a position signal of the touch ground nail 7 and a control module (not shown in the figure) for controlling the start and stop of the motor according to the obtained trigger position signal to implement intermittent spraying operation, and the travel switch 6 is circuit-connected with the control module.

[0032] The utility model discloses, the action of travel switch 6 is to distinguish touch peg 7, that is used for obtaining the position signal of touch peg 7, and it can also be an induction switch (for example electromagnetic induction switch), and can also be a camera and the like visual identification sensor or radar and the like induction identification sensor.The effect of control module is to control the motor start-stop according to the obtained trigger position signal and then implement intermittent travel type spraying operation, and according to the different types of sensor or induction switch, it can be circuit connection or communication connection between the control module.Touch peg 7 is a trigger, and the effect is to trigger the motor automatic start-stop device at the set position, in order to adapt to the induction switch or sensor, the trigger can also be selected as the identifiable marker (such as color point or two-dimensional code) of sensor, and will not be listed one by one.

[0033] As Figures 1 to 4 The utility model discloses, the action of travel switch 6 is to distinguish touch peg 7, that is used for obtaining the position signal of touch peg 7, and it can also be an induction switch (for example electromagnetic induction switch), and can also be a camera and the like visual identification sensor or radar and the like induction identification sensor.The effect of control module is to control the motor start-stop according to the obtained trigger position signal and then implement intermittent travel type spraying operation, and according to the different types of sensor or induction switch, it can be circuit connection or communication connection between the control module.Touch peg 7 is a trigger, and the effect is to trigger the motor automatic start-stop device at the set position, in order to adapt to the induction switch or sensor, the trigger can also be selected as the identifiable marker (such as color point or two-dimensional code) of sensor, and will not be listed one by one.

[0034] According to the height of crop in the greenhouse, the installation height of the fog outlet 42 is adjusted to avoid the direct spraying of the fog outlet 42 to the treated branches and leaves of the crops, the spraying machine is started, and intermittent travel type spraying operation is implemented, one cycle of intermittent travel type spraying operation includes a walking stage and a stopping stage, when reaching a specified position, the spraying machine is switched from the walking stage to the stopping stage, in the stopping stage, the spraying machine stops advancing and sprays pesticide fog to the space between the two rows of crops, after the stopping stage is finished, the spraying machine is switched to the walking stage again, and spraying or non-spraying can be selected in the walking stage.

[0035] When in use, a plurality of triggers are arranged at intervals along the walking route of the spraying machine, the duration of the stopping stage is set through the control module, when the trigger triggers the motor automatic start-stop device, the spraying machine is switched from the walking stage to the stopping stage, and is switched to the walking stage again after a specified duration, until reaching the next trigger. In the stopping stage, the spraying machine stops advancing and sprays pesticide fog to the space between the two rows of crops, and there is no crop branch or sparse crop branches between the two rows of crops, so that the pesticide fog cannot be directly sprayed to the treated branches and leaves of the crops.

[0036] Further, the control module sets the disable time of the walking stage, and in the disable time, the travel switch, the inductive switch or the sensor is in the disabled state, so that the motor does not stop even if the inductive switch, the travel switch or the sensor is triggered by the hard-to-clean object (for example, the column), and the spraying pesticide machine also does not stop walking. By setting the length of the disable time, the disable time is less than the time required for the spraying pesticide machine to travel from one trigger to the next trigger, so that when the inductive switch, the travel switch or the sensor resumes the enabled state after the end of the disable time, the pesticide spraying machine can be very close to the next trigger, so that the cleaning workload of the objects between the two triggers can be greatly reduced, and the inconvenience of the moving facility can be avoided.

[0037] In summary, the spraying pesticide machine disclosed by the utility model creatively combines the height adjustment of the mist outlet 42 with the intermittent walking type spraying operation, greatly reduces the probability of the pesticide mist directly sprayed to the treated branches and leaves of crops, reduces or avoids the pesticide damage and waste, and improves the pesticide efficiency.

[0038] In addition, in the embodiment, a pressure switch (not shown in the figure) is arranged on the pipeline of the gas supply system, the pressure switch is electrically connected with the water pump control circuit, when the high-pressure gas pressure provided by the gas supply system is insufficient, the water pump can be stopped by the pressure switch to prevent the waste of the pesticide liquid, the pollution of the pesticide liquid or the damage of the device. Meanwhile, in the starting stage of the spraying pesticide machine, the gas pressure of the gas supply system rises slowly, the water pump can be delayed to start by the pressure switch, and the service life of the water pump is effectively protected.

[0039] The utility model is not limited to the above-mentioned embodiments, all kinds of improvements based on the conception, principle, structure and method of the utility model will fall into the protection scope of the utility model.
