Problems solved by technology

Due to different ground conditions, the load of the generator on the spraying machine also changes from time to time, and the heat generation of the rectifier bridge also changes. When the load is large, the heat generation of the rectifier bridge is relatively large. If there is no good heat dissipation, the rectifier bridge will easily burn out
The heat dissipation of the rectifier bridge in the prior art mostly uses the fan to blow the air to the rectifier bridge for air cooling and heat dissipation. The heat dissipation effect of this method is not obvious, and the fan needs to consume additional electric energy. The water tank, circulation pump and circulation pipeline, etc. increase the manufacturing cost, and due to the limitation of the spray mechanical load, the circulation water tank is set small, which affects the water cooling and heat dissipation

Abstract

The invention relates to a generator heat dissipation system of a spraying machine. The system comprises a vehicle body, a power device and a spraying system, the power device and the spraying system are arranged on the vehicle body, the power device comprises an internal combustion engine and a generator connected with the internal combustion engine, the spraying system comprises an agent box, liquid conveying pipes, a pump and a spraying head, and the agent box is connected with the pump through the liquid conveying pipe; and the pump is connected with a liquid cooling radiator through the liquid conveying pipe, and the liquid cooling radiator is connected with the spraying head through the liquid conveying pipe and assembled on the generator. According to the generator heat dissipation system of the spraying machine, agent liquid carried in the agent box serves as cooling liquid, the agent liquid flows through the liquid cooling radiator on the generator in the spraying operation process and during field edge transition, heat transmitted to the liquid cooling radiator by the generator is taken away, heat dissipation and cooling of the generator are achieved, the amount of the agent liquid carried in the agent box is large, the agent liquid is used as the cooling liquid, a cooling liquid container does not need to be carried independently, and a cooling device for cooling the agent liquid does not need to be arranged when the amount is large.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a generator cooling system for a sprayer. Background technique [0002] The rectifier bridge has the characteristics of small size and convenient use. It is widely used in household appliances and industrial electronic circuits. It uses the unidirectional conduction characteristics of diodes to complete the conversion of alternating polarity alternating current into direct current with constant polarity. This is The role of the rectifier bridge. The maximum forward average current that the rectifier bridge diode allows to pass through for a long time, its value is related to the PN junction area and external heat dissipation conditions. Under the condition of external heat dissipation, if the average forward current of the diode exceeds this value, it will burn out due to the increase of temperature. Due to different ground conditions, the load of the generator on the spra...
