Description

Technical Field

[0001] The utility model relates to the technical field of grain cooling, in particular to a grain cooler with a cleaning device. Background Art

[0002] After the grains are collected and stored, in order to avoid damage or deterioration caused by excessive temperature or moisture in the grains, a cooler is usually used to cool the grains, thereby extending their storage time and keeping the grains in a dry state. For example, a grain cooler with publication number CN111750556B includes a body, a condenser and a hot air blower are arranged in the body, and a spray device is provided. When the temperature outside the warehouse is high, a valve is opened to spray water around the condenser. The water evaporates and absorbs heat to meet the heat dissipation requirements of the condenser. There is no need for the fan to rotate at high speed, thereby avoiding the use of a high-speed fan and achieving the effect of using a cooler in a dusty environment. However, the grain cooler still has the following disadvantages in actual use:

[0003] Although the above-mentioned cooler can cool the grains, it cools and dries the grains by blowing air. The blown gas will drive the dust on the grains to the air outlet of the storage box, which may easily cause blockage in the gas transportation. In addition, the gas is directly discharged after passing through the inside of the storage box, resulting in partial gas waste. There is a lack of structure for gas recycling. In view of the above problems, it is urgently necessary to carry out innovative design based on the original grain cooler. Utility Model Content

[0009] Preferably, the movable tube and the machine body are slidably connected, and a spring is wound around one end of the movable tube close to the first hose. The movable tube can slide on the machine body to ensure the tightness of the connection box and the top of the storage box.

[0010] Preferably, a connecting box is fixed to the end of the movable tube away from the first hose, and fixing holes are evenly reserved on the lower end surface of the connecting box, and the two connecting boxes respectively cover the outside of the air inlet and the air outlet. When the gas is blown into the storage box through the air inlet, the gas is then discharged through the air outlet.

[0013] Compared with the prior art, the utility model has the following beneficial effects: when the grain cooler with a cleaning device cools and dries the grains by blowing air, the dust on the grains can be taken out synchronously, which plays a cleaning role and prevents blockage during gas transportation. In addition, the gas flowing through the storage box can be recovered and then recycled. The specific contents are as follows:

[0014] 1. Pull the movable tube to slide on the machine body, and the upper connection box is driven down by the resilience of the spring and contacts the air inlet hole. Then the gas generated by the rotation of the fan blades enters the movable tube through the first hose, and then enters the connection box, and blows into the storage from the fixed hole, cooling and drying the grain inside, thus extending the storage time of the grain.

Then the dust passes through the connecting box and the fixed pipe into the collecting box, and is intercepted by the filter to facilitate subsequent dust discharge. At the same time, the filtered gas can be transmitted to the movable pipe through the second hose to realize the recycling of the gas. BRIEF DESCRIPTION OF THE DRAWINGS
