Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] As Figure 1 , Figure 3 , Figure 5 and Figure 6 indicated, the utility model is a winnowing machine, which is applied to wood processing, removes impurities from the wood shavings processed from wood, mainly removes some mud, gravel, glass and metal and other heavy substances; specifically, the winnowing machine comprises a winnowing box 1, the winnowing box 1 side forms a feed inlet 2 and forms a lower box body 3 connected in communication below, the lower box body 3 is communicated with a fan assembly 7, preferably, the fan assembly 7 comprises an adjusting device 72 communicated with the winnowing box 1 and a fan 71 communicated with the adjusting device 72, the adjusting device 72 can adjust the wind direction or wind force of the fan 71 blowing into the winnowing box 1, the adjusting device 72 can be internally provided with an adjusting structure, such as a wind deflector, etc., and can directly adopt the existing adjusting equipment on the market to adjust, only the effect of adjusting the wind direction or wind force or wind speed is needed; further, the winnowing box 1 top surface is sequentially communicated with a conical cavity 5 and a discharge pipe 6.

[0029] The utility model discloses a wind selection box 1 is divided into the fixed box body 11 and the folding box body group 12 of mutual cover connection of installation on the chassis 41 and installation in the top frame 42, the fixed box body 11 and the folding box body group 12 are installed on the different frame structure and can make the fixed box body 11 and the folding box body group 12 be independent of each other, and the inlet 2 and the lower box body 3 of the above-mentioned are formed on the side surface and the bottom surface of the fixed box body 11 respectively, and the conical cavity 5 and the discharge pipe 6 of the above-mentioned are communicated in the top surface of the folding box body group 12 in proper order.

[0030] As Figure 1 , Figure 3 and Figure 6 , the utility model discloses the wind selection box 1 is divided into the fixed box body 11 and the folding box body group 12 of mutual cover connection of installation on the chassis 41 and installation in the top frame 42, the fixed box body 11 and the folding box body group 12 are installed on the different frame structure and can make the fixed box body 11 and the folding box body group 12 be independent of each other, and the inlet 2 and the lower box body 3 of the above-mentioned are formed on the side surface and the bottom surface of the fixed box body 11 respectively, and the conical cavity 5 and the discharge pipe 6 of the above-mentioned are communicated in the top surface of the folding box body group 12 in proper order.

[0031] More specifically, as Figure 1 and Figure 3 , the folding box body group 12 is divided into the first box body 121, the second box body 122 and the third box body 123 of sliding connection in proper order, specifically, the third box body 123 is slidably sleeved outside the second box body 122, the second box body 122 is slidably sleeved outside the first box body 121, and the first box body 121 is fixedly installed into the top frame 42, in this way, the third box body 123 and the second box body 122 can be folded into the first box body 121 in proper order, further, the fixed first box body 121 is provided with a screen 124, and the screen 124 is used for carrying out preliminary filtration to the wind selection box 1, for example, some shavings are too large in volume, but its mass is relatively light and easily flows along the selected airflow, at this time, the screen 124 can filter out these shavings, and the wind selection quality is improved.

[0032] In order to improve the sealing effect of the wind selection box 1, as Figure 4 , the top surface edge of the fixed box body 11 is formed with a sealing strip 125, and the third box body 123 is lowered and attached to the top surface of the fixed box body 11 and is clamped with the sealing strip 125 to achieve a sealing effect.

[0033] Since the wood shavings adhering to the inner walls of the second and third boxes 122 and 123 are easily scraped off when the second and third boxes 122 and 123 are folded toward the first box 121, Figure 4 As shown, a collecting tray 126 is formed at the bottom of the inner wall of the third box body 123 , and the collecting tray 126 can be disassembled relative to the third box body 123 , so that the wood shavings in the collecting tray 126 can be easily removed and cleaned.

[0034] In order to realize automatic folding of the folding box group 12 without manual operation, Figure 1 、 Figure 3 、 Figure 6 and Figure 7 As shown, the third box 123 is connected to the lifting device 8. Specifically, the lifting device 8 includes a winding motor 81 installed on the top frame 42, a winding drum 82 installed on the main shaft of the winding motor 81, and the winding drum 82 is connected to the bottom of the third box 123 through a traction rope 84. Preferably, the traction rope 84 is connected to the connecting seat 85 of the third box 123; preferably, as shown Figure 1 As shown, in order to extract three points at the same time and make the third box 123 receive the extraction force evenly, the traction rope 84 is turned and wound around the two measurements of the third box 123 and one end face of the third box 123 through the transition pulley 83. At this time, the traction rope 84 is wound by the winding motor 81 to pull up the three points of the third box 123 at the same time, making the lifting more stable and uniform.

[0035] After the folding box group 12 is folded up, the second box 122 and the third box 123 are prone to fall due to their own weight. Therefore, the present invention is further optimized. Specifically, Figure 1 and Figure 2 As shown, the air separator of the present invention further includes an anti-drop device 9. More specifically, the anti-drop device 9 includes a cylinder 92 mounted on the top frame 42 via a connecting seat 91, a first stopper 94 connected to a push rod 93 of the cylinder 92, and a second stopper 95 whose ends are slidably inserted into the two first stoppers 94. Figure 1 and Figure 6As shown, the installation of the four air cylinders 92 has certain angle requirements, when not in use, the four air cylinders 92 simultaneously pull the push rod 93 at a certain angle, the air cylinder 92 can retract the push rod 93 and will not be dead by the first stop lever 94 and the second stop lever 95, the push rod 93 pulls the first stop lever 94 and the second stop lever 95 to expand outward, in this state, the first stop lever 94 and the second stop lever 95 will not interfere with the folding box body group 12; when in use (when the folding box body group 12 needs to be prevented from folding and falling), the four air cylinders 92 simultaneously push the push rod 93 at a certain angle, the first stop lever 94 and the second stop lever 95 move inward and retract below the bottom surface of the third box body 123, if the third box body 123 falls, it will be supported by the first stop lever 94 and the second stop lever 95, improving safety and preventing accidents.

[0036] Further optimization, the air inlet of the fan 71 is communicated to the cyclone separator through the air pipe 10, the cyclone separator is used for removing particles or liquid drops in the gas, the fan 71 inhales the gas in which impurities are removed, so that the winnowing airflow is more pure, especially if the airflow contains oil, which will pollute the winnowed shavings and affect the forming quality of the subsequent shaving board.

[0037] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
