[0002] At present, the heat source of grain dryers often uses boilers, fuel burners, etc. Among them, boilers are one of the commonly used heat sources for grain drying machinery. In the past, the fuel was often coal. The burning of coal will pollute the environment. As we all know, environmental and environmental issues are extremely important to the public. In recent years, with the emergence of a new type of clean, efficient and environmentally friendly energy - biomass pellets, biomass pellet furnaces for grain dryers have also become popular.

[0003] In the prior art, the patent number: CN218001820U discloses a biomass hot air furnace with a heat preservation structure, which solves the problem that the biomass hot air furnaces on the market in the prior art are affected by the environment during use. If the outside temperature is too low, the temperature inside the furnace cannot be kept warm for a long time, which reduces the efficiency of the hot air furnace, and the heat in the exhaust gas from the hot air furnace cannot be effectively recycled to help the hot air furnace achieve the heat preservation function. A biomass hot air furnace with a heat preservation structure includes a furnace body, an exhaust pipe is connected to one side of the top of the furnace body, and the outer ring of the furnace body is detachably connected to an insulation pipe, and a water pump is installed on one side of the top of the furnace body. The utility model increases the heat preservation function of the hot air furnace through structural design, maximizes its working efficiency, and the recovered heat avoids the waste of resources, effectively utilizes the recovered resources, and reduces the cost of use.

[0004] Although the above-mentioned biomass hot air furnace can achieve the effect of heat insulation in the furnace by setting up components such as insulation pipes and heat conducting rods, it still has the following shortcomings in practical applications: after combustion in the hot air furnace, a large amount of smoke and dust will accumulate on its inner wall, which is extremely troublesome to clean manually.

[0012] Preferably, a plurality of supporting legs are evenly and symmetrically installed on the bottom of the hot blast stove body.

[0013] The beneficial effects of the utility model are as follows: when cleaning the device, the main gear is driven to rotate by starting the motor, and the main gear drives the inner gear ring meshing therewith to rotate, thereby driving the two cleaning plates fixedly installed between the inner gear ring and the connecting ring to rotate. The rotation of the cleaning plates will scrape off the smoke and dust debris accumulated on the inner wall and the bottom inner wall of the hot blast furnace body, so that they are discharged from the discharge port, and multiple vibrators are started to vibrate the top wall of the hot blast furnace body, thereby shaking off the smoke and dust on the top inner wall of the hot blast furnace body, so that the device can automatically clean the inside thereof, reducing the labor intensity of manual labor; when the exhaust pipe needs to be cleaned, it is only necessary to rotate the exhaust pipe, rotate it and unscrew it from the exhaust port, and then clean it, which is convenient for workers to install and disassemble the exhaust pipe and clean it.
