[0002] The grain drying tower adopts a rotary heating device, which can generate a large amount of hot air in a short time. It can kill insect eggs through high temperature treatment and completely solve the discoloration phenomenon during the drying process. The drying tower body adopts metal inner wall plate, silicone cotton insulation, corrugated color steel plate or aluminum alloy outer wall plate. Digital control and detection are adopted in the box body to effectively control air circulation, humidification and heating. The drying tower is equipped with an air intake angle box and an exhaust angle box with mesh through holes on both sides. The air intake angle box and the exhaust angle box are arranged alternately. Grain flows from top to bottom on the outside of the angle box, and the drying medium flows horizontally. Hot air enters from the air intake angle box and passes through the grain layer in the up and down directions. The exhaust gas is discharged through the exhaust angle box to achieve the purpose of uniform heating of the grain. The hot air passes through the high-moisture grain and takes away the light impurities in the grain, so that the inner cavity of the exhaust angle box will adhere to many paste impurities. If the impurities are not cleaned in time, the ventilation and drying effect of the angle box will be seriously affected, and the angle box will be corroded and the service life of the angle box will be reduced. The cleaning of the inner cavity of the corner box is very important. After the operation season is over, the inner cavity of the corner box needs to be effectively cleaned.

[0031] Specifically, the second handle 2 can be used to fix and connect the middle scraper 4, the spring buckle 3 can be used to play the role of a card and a hole, thereby fixing the length range of the second handle 2 and the first handle 1, and the first handle 1 can be used to increase the length of the second handle 2, thereby more conveniently adapting to the length of the angular box, and the inner diameter of the first handle 1 is equal to the outer diameter of the second handle 2, thereby making the first handle 1 and the second handle 2 more compatible, thereby improving the integrity when using the tool, thereby improving work efficiency, and the outer wall of the first handle 1 is provided with multiple Holes at different positions can make the spring buckle 3 snap in different positions and adjust to a suitable length. The hole diameter is equal to the outer diameter of the spring buckle 3, so that the spring buckle 3 and the hole are snapped more tightly to avoid loosening. The end cover 6 can limit the movement of the middle scraper 4. The outer edge of the end cover 6 is provided with a flat edge, so that it can abut the upper rib plate 401 and the lower rib plate 402. Therefore, when the second handle 2 drives the end cover 6 to rotate, the rotation angle can be limited to 90 degrees, avoiding the first handle 1 and the second handle 2 from not rotating into place, affecting the normal opening and closing of the side scraper 5.

[0032] Please see attached Figure 7 The fastening structure includes a screw, which is threadedly connected to the end cover 6 and the interior of the second handle 2.

[0033] Specifically, the end cover 6 can be stably, efficiently and quickly fixed inside the second handle 2 by screws, thereby clamping the middle scraper 4 to prevent it from falling off during use.

[0034] Please see attached Figure 3 -Attached Figure 4An intermediate scraper 4 is provided between the end cover 6 and the second handle 2 , and a self-lubricating bearing 7 is provided between the intermediate scraper 4 and the second handle 2 .

[0035] Specifically, the middle scraper 4 can be used to scrape out impurities on the top of the angular box. The top of the middle scraper 4 is triangular, which can better fit the shape of the angular box, thereby further improving the efficiency of removing impurities. The self-lubricating bearing 7 can make the second handle 2 rotate more smoothly inside the middle scraper 4.

[0037] Specifically, the upper rib plate 401 and the lower rib plate 402 can limit the rotation range of the side scraper 5. At the same time, the upper rib plate 401 and the lower rib plate 402 are on the side away from the second handle 2, thereby increasing the strength of the middle scraper 4 and thus increasing the durability of the middle scraper 4.

[0038] Please see attached Figure 3 -Attached Fig. 9 The two sides of the middle scraper 4 are connected to the side scrapers 5 through hinges. The side scrapers 5 are located on the side of the upper rib plate 401 and the lower rib plate 402 close to the second handle 2, and the hinges are located at the upper part of the upper rib plate 401 and the lower part of the lower rib plate 402.

[0039] Specifically, the side scraper 5 can scrape out impurities on the side wall of the angular box. The edge of the side scraper 5 is triangular, so that it can better fit the side wall and corners of the angular box, thereby further improving the effect of cleaning impurities on the side wall.

[0040] Please see attached Figure 3 -Attached Fig. 9 The two side scrapers 5 are symmetrically arranged through the central axis of the middle scraper 4.

[0041] Specifically, the symmetrical arrangement can match the corner shape of the middle scraper 4, thereby avoiding the scraping of impurities.

[0042] Please see attached Figure 5 -Attached Fig. 9 A paddle plate 201 is fixedly connected to one side of the second handle 2 close to the middle scraper plate 4, and the edge of the contact surface of the paddle plate 201 close to the middle scraper plate 4 is in a raised shape.

[0043] Specifically, the side scraper 5 can be opened by the paddle 201. The edge of the contact surface of the paddle 201 close to the middle scraper 4 is in a raised shape, so that the side scraper 5 can be better contacted when the paddle 201 is rotated, thereby improving the efficiency of opening the side scraper 5.

[0044] Please see attached Figure 3 The end cover 6 is located between the upper rib plate 401 and the lower rib plate 402 .

[0045] Specifically, the force point for scraping away debris can be more centered, so that when the middle scraper 4 and the side scraper 5 are pulled out by the second handle 2, they remain parallel to the cross section of the angular box, avoiding tilting and causing gaps with the edge of the angular box.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
