When the collection box 200 is taken out from the socket, it is convenient to discharge and clean the ash collected in the collection box 200, so that the biomass hot air furnace can discharge ash more conveniently;

[0026] When it is actually used, the side wall of the collection box 200 fits with the side wall of the furnace and the grate, so that the ash dropped from the grate can be better collected in the collection chamber 201;

[0027] In this embodiment, the front side wall of the collection box 200 extends outward at both sides to form an overlapped portion overlapped on the front side of the furnace body, and a sealing gasket is provided at the overlapped portion, thereby ensuring the sealing of the collection box 200; wherein, a handle 204 is provided on the front side wall of the collection box 200, and the handle 204 can be used to facilitate the operator to pull out the collection box 200, making it more convenient to use;

[0028] In this embodiment, by setting the installation cavity 202, the plug-in component, the plug-in slot and the driving component, when the collection box 200 is extended into the furnace, the driving component drives the plug-in component to extend out of the installation cavity 202 and insert into the corresponding plug-in slot, so that the collection box 200 can be preferably fixed in the furnace. At this time, the driving component can drive the plug-in component to retract into the installation cavity 202, thereby releasing the fixation of the collection box 200, so that the collection box 200 can be more conveniently drawn in the furnace.

[0029] Among them, by setting up the leveling component, it is possible to level the ash and slag dropped from the grate into the collecting chamber 201, so as to avoid excessive accumulation of ash and slag, which would affect the ash discharge effect of the grate.

[0030] Combination Figure 3 As shown, in this embodiment, mounting rods 203 are relatively arranged in the mounting cavity 202 along the left and right directions thereof, and the plug-in component includes a parallelly arranged plug-in board 300, on which a mounting plate 301 is provided for the corresponding mounting rod 203 to pass through, and plug-in tongues 302 are provided at the ends of the plug-in board 300 that are away from each other, and a first spring 210 for driving the plug-in tongue 302 to extend out of the collection box 200 is sleeved on the mounting rod 203, and the driving component is used to drive the plug-in board 300 to move relative to achieve the retraction of the plug-in tongue 302.

[0031] In actual use of this embodiment, the plug board 300 is arranged in parallel with the corresponding mounting rod 203, and the mounting rod 203 passes through the mounting plate 301, so that the plug board 300 can be stably installed in the mounting cavity 202;

[0032] Among them, by setting the first spring 210, the first spring 210 pushes the mounting plate 301 to drive the two plug-in plates 300 to move closer to each other, so that the plug-in tongues 302 on the plug-in plates 300 extend out of the collection box 200, so that they are plugged into the corresponding plug-in slots, which can better achieve the fixing of the collection box 200 in the furnace;

[0033] Among them, the driving member is used to drive the two plug-in boards 300 to move away from each other, so that the plug-in tongue 302 on the plug-in board 300 retracts into the collection box 200, releasing its cooperation with the plug-in slot, that is, releasing the fixation of the collection box 200, so that the collection box 200 can be pulled out and placed in the furnace.

[0034] In this embodiment, the driving member includes a lifting plate 320 arranged between the plug-in boards 300 through a second spring 310, and a pressing rod 321 is provided on the lifting plate 320 and extends through the front side of the collection box 200.

[0039] In this embodiment, limiting blocks (not shown in the figure) are arranged on the opposite side walls of the collecting chamber 201 in the front-to-back direction, and limiting grooves (not shown in the figure) are arranged at both ends of the push plate 220 for the corresponding limiting blocks to be inserted into, thereby achieving a better smooth sliding of the push plate 220 in the collecting chamber 201;

[0040] Among them, through the setting of the lever 221, the operator can pull the lever 221 outside the furnace body 100 to drive the push plate 220 to slide back and forth in the collection chamber 201, so that the ash pile accumulated in the collection chamber 201 can be flattened, thereby ensuring the ash discharge effect of the grate.

[0041] Working principle: When ash discharge is required, the operator holds the handle 204 and presses the pressing rod 321 with the thumb, which can drive the plug-in tongue 302 to retract into the collection box 200, thereby releasing the fixation of the collection box 200. At this time, the collection box 200 can be pulled out by pulling the handle 204 to discharge ash. After the ash discharge is completed, the operator holds the handle 204 and presses the pressing rod 321 with the thumb, and at the same time inserts the collection box 200 into the furnace. Loosening the pressing rod 321 can extend the plug-in tongue 302, thereby fixing the collection box 200 in the furnace.

[0042] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
