Abstract

The invention relates to a grain cooling machine. The grain cooling machine comprises a machine body, wherein a condenser, a hot air blower and a spraying device are arranged in the machine body; thespraying device comprises a spray pipe and a regulating valve; one end of the spray pipe is closed, and the other end of the spray pipe communicates with a water source through the regulating valve; water spraying holes are formed in the spray pipe at intervals; the spray pipe is located above the condenser, and the water spraying holes face downwards; the regulating valve comprises a valve and aregulating assembly; the valve comprises a valve body and a valve rod; the valve rod is rotationally connected with the valve body; and the regulating assembly is used for controlling the valve rod torotate so as to control the opening degree of the valve. According to the grain cooling machine, when the temperature outside a bin is high, the valve is opened, water is sprayed to the peripheral side of the condenser, and the water evaporates and absorbs heat, so that the heat dissipation requirement of the condenser is met without a high speed rotating of a fan, then the use of the fan with ahigh rotating speed is avoided, and the effect of using the cooling machine in a dusty environment is achieved.

Description

technical field [0001] The present application relates to the field of cooling machines, in particular to a grain cooling machine. Background technique [0002] Grain coolers are mainly used in granaries, storage warehouses and other places to reduce the air temperature. [0003] The grain cooler mainly includes a body and a compressor, a condenser, an expansion valve, an evaporator and a cooling fan placed in the body. [0004] Its working principle is: the medium circulates among the compressor, condenser, expansion valve and evaporator. After being compressed by the compressor, the medium is in a high-temperature state, and the high-temperature medium enters the condenser, and exchanges heat with the air outside the warehouse at the condenser to realize the cooling of the medium; then, the cooled low-temperature medium is expanded by the expansion valve Entering the evaporator, the low-temperature medium exchanges heat with the air sucked by the cooling fan at the evapo...
