[0002] In the existing production process of bamboo and wood products, a large amount of bamboo and wood chips are generated, and the bamboo and wood chips can be recycled for mushroom cultivation and environmentally friendly decorative materials, so that the bamboo and wood chips are recycled and reused to avoid waste of resources. However, after the bamboo and wood chips are collected, they contain moisture, which makes them heavier as a whole, affecting subsequent transportation work. Therefore, the bamboo and wood chips need to be dried and then packaged for transportation.

[0039] Here is how the above example works:

[0040] When in use, the motor 4 is connected to the power supply, the feed pipe 3 is connected to the external feeding device, the air intake pipe 11, the air intake pipe 201 and the air intake pipe 3 207 are connected to the external pump, the external suction device is connected to the air suction port 21 on the right side of the drying box 2 2, and the output end of the external suction device is provided with an electric heating wire, and the output end of the external suction device is connected to the suction end of the external pump.

[0041] The external feeding device is controlled to convey the bamboo and wood chips into the drying box 1 through the feeding pipe 3, and the external pump is controlled to pass the hot air into the drying box 1 through the air inlet pipe 11, so that the hot air dries the bamboo and wood chips. Then the motor 4 is controlled to drive the circular plate 5, the spiral plate 6 and the straight plate 7 to rotate clockwise from left to right, so that the spiral plate 6 drives the straight plate 7 to stir the bamboo and wood chips, so that the bamboo and wood chips are dispersed under the stirring of the straight plate 7, so that the dispersed bamboo and wood chips are better dried by the hot air. As the spiral plate 6 continues to rotate, the bamboo and wood chips will be pushed to the right by the spiral plate 6. With the stirring of the straight plate 7 and the blowing of the hot air, the bamboo and wood chips are gradually dried. In the process of drying the bamboo and wood chips, the external suction device draws away the hot air in the drying box 1 and the drying box 2 through the exhaust port 21. When the dried bamboo and wood chips move to the connection between the drying box 1 and the drying box 2, the dried bamboo and wood chips will be transferred with the hot air being sucked away. At this time, the dried bamboo and wood chips are intercepted by the filter cloth 304, and the bamboo and wood chips transferred with the hot air will fall into the discharge frame 305, and then the bamboo and wood chips in the discharge frame 305 are collected by the external collecting device. When the external suction device draws the hot air away, the external suction device transports the hot air to the external pump connected to the air inlet pipe 11, the air inlet pipe 201 and the air inlet pipe 3 207, thereby realizing hot air circulation to dry the bamboo and wood chips. When the hot air is transported to the external pump through the external suction device, the hot air is heated by the heating wire on the output end of the external suction device to ensure the temperature of the hot air and the drying effect of the bamboo and wood chips.

[0042] It is considered that since the bamboo and wood chips just produced by processing have more moisture, when the chips are collected and piled together, they are easy to cause the bamboo and wood chips to stick to each other and form a mass. It is difficult to effectively disperse the agglomerated bamboo and wood chips through the stirring of the straight plate 7, which makes it difficult for the hot air to effectively dry the agglomerated bamboo and wood chips. Therefore, when the circular plate 5 drives the spiral plate 6 to rotate, the spiral plate 6 drives the straight plate 7 to rotate synchronously, so that the straight plate 7 rotates synchronously. Since the plurality of straight plates 7 are combined into a horizontally arranged grid, when the grid composed of the plurality of straight plates 7 rotates synchronously with the spiral plate 6, the agglomerated bamboo and wood chips will be blocked, and the dispersed bamboo and wood chips will pass through the straight plate 7. The agglomerated bamboo and wood chips will fall into the crushing bin 8 with the rotation of the straight plate 7. At the same time, the circular plate 5 drives the spiral plate 6 and the straight plate 7 to rotate. When the straight plate 7 moves, the connecting plate 9 and the connected crushing plate 10 will be driven to rotate synchronously. When the crushing plate 10 on the connecting plate 9 rotates, the bamboo and wood chips that fall into the crushing bin 8 will be driven to move. Therefore, when the crushing plate 10 on the connecting plate 9 and the crushing plate 10 in the crushing bin 8 are engaged with each other and separated, the crushing plates 10 on the connecting plate 9 and the crushing plates 10 in the crushing bin 8 are used to crush the agglomerated bamboo and wood chips, so as to avoid the bamboo and wood chips that are just processed and have more moisture. When the chips are collected and piled up, it is easy to cause the bamboo and wood chips to stick to each other and form a mass. It is difficult to effectively disperse the agglomerated bamboo and wood chips through the stirring of the straight plate 7, which leads to the problem that the drying of the bamboo and wood chips is affected. In addition, the crushing plates 10 on the connecting plate 9 squeeze the crushed bamboo and wood chips into the crushing bin 8. The hot air ejected from the air inlet pipe 11 blows the bamboo and wood chips in the crushing bin 8 to the left, so that the bamboo and wood chips are transferred from the notch 2001 on the connecting plate 9 and the baffle to the notch 81, and then fall into the drying box 1 through the notch 81, and then are pushed to the right by the spiral plate 6. After the clumped bamboo and wood chips are crushed, the clumped bamboo and wood chips have more residual moisture after crushing than the originally dispersed bamboo and wood chips, which will affect the drying effect of the hot air when mixed with the dispersed bamboo and wood chips. Therefore, the clumped bamboo and wood chips are moved to the crushing bin 8 for crushing, so as to avoid the problem that the bamboo and wood chips after crushing have more residual moisture, which will affect the drying effect of the hot air when mixed with the dispersed bamboo and wood chips, and the air inlet pipe 11 is set at the crushing bin 8. On the right side of the crushing bin 8, the hot air ejected from the air inlet pipe 11 is blown to the left side and directly blown to the surface of the crushed bamboo and wood chips in the crushing bin 8. By blowing the hot air directly into the crushing bin 8, the bamboo and wood chips with more moisture are dried by the hot air first, thereby accelerating the drying speed. At the same time, through the notch 2001 set on the connecting plate 9 and the baffle plate, the bamboo and wood chips can pass through the notch 2001 only when the notch 2001 is rotated to the bottom, and the hot air is blown. This method increases the drying time of the bamboo and wood chips and improves the drying efficiency by limiting the discharge amount of the bamboo and wood chips. When the straight plate 7 drives the agglomerated bamboo and wood chips to be transferred to the crushing bin 8, the inclined surface 182 set on the crushing bin 8 prevents the agglomerated bamboo and wood chips from falling on the upper surface of the crushing bin 8.The problem of bamboo and wood debris remaining.

[0043] Considering that the bamboo and wood chips just entering the drying box 1 from the feeding pipe 3 are in a wet state, when the straight board 7 pushes the wet bamboo and wood chips, the wet bamboo and wood chips will stick together, resulting in the wet bamboo and wood chips being unable to pass through the grid composed of multiple straight boards 7, thereby causing the wet bamboo and wood chips and the agglomerated bamboo and wood chips to be driven by the straight board 7 to the inner left part of the crushing bin 8, and then being crushed by the two crushing boards 10, and then being blown by the hot air ejected from the air inlet pipe 11, and then entering the drying box 1 again, and so on, causing the bamboo and wood chips to be accumulated on the left side of the drying box 1, affecting the drying operation of the bamboo and wood chips, therefore, when When the agglomerated bamboo and wood chips and the wet bamboo and wood chips are located in the left half of the crushing bin 8 and are driven by the straight plate 7, the left half of the crushing bin 8 is set to a hollow cylindrical shape, and the right half is set to a semicircular shape. When the straight plate 7 follows the spiral plate 6 to rotate, the straight plate 7 drives the agglomerated bamboo and wood chips and the wet bamboo and wood chips to move to the upper part of the drying box 1. When the wet bamboo and wood chips and the agglomerated bamboo and wood chips break away from the straight plate 7 and fall into the left half of the crushing bin 8, the wet bamboo and wood chips and the agglomerated bamboo and wood chips will slide along the surface of the left half of the crushing bin 8 and fall back into the drying box 1, and then the wet bamboo and wood chips and the agglomerated bamboo and wood chips are driven by the spiral plate 6. The wet bamboo and wood chips move to the right side, and when the wet bamboo and wood chips and the agglomerated bamboo and wood chips move to the right half of the crushing bin 8 under the drive of the spiral plate 6, the wet bamboo and wood chips and the agglomerated bamboo and wood chips are dried by the hot air at this time, and the wet bamboo and wood chips are gradually dried, and the surface of the agglomerated bamboo and wood chips is gradually dried. At this time, the dry bamboo and wood chips can pass through the straight plate 7, and the agglomerated bamboo and wood chips will still be driven by the straight plate 7 into the crushing bin 8. With the continuous rotation of the spiral plate 6, when the agglomerated bamboo and wood chips move into the crushing bin 8, the motor 4 drives the connecting plate 9 and the crushing plate 10 to rotate clockwise from left to right, so that the crushing plate on the connecting plate 9 is The crushing plate 10 and the crushing plate 10 on the crushing bin 8 are interlocked and separated, so that the crushing plate 10 on the connecting plate 9 and the crushing plate 10 in the crushing bin 8 crush the clumped bamboo and wood chips, so that the wet bamboo and wood chips and the clumped bamboo and wood chips are dried first, and then the clumped bamboo and wood chips are crushed, thereby avoiding the wet bamboo and wood chips and the clumped bamboo and wood chips being driven to the inner left part of the crushing bin 8 by the straight plate 7, and then being crushed by the two crushing plates 10, and then being blown into the drying box 1 by the hot air ejected from the air inlet pipe 11, causing the bamboo and wood chips to be accumulated on the left side of the drying box 1, affecting the drying problem.

[0044] It should be noted that the purpose of combining the straight plates 7 into a grid arranged only horizontally is that, in addition to fine fragments, bamboo and wood debris also exist in thin flakes. If the clumped bamboo and wood debris are screened through a filter, the thin flakes cannot pass through the filter, resulting in the accumulation of flaky bamboo and wood debris and clogging the filter. Therefore, by setting a plurality of straight plates 7 to form a grid arranged only horizontally, it is avoided that the clumped bamboo and wood debris is screened through the filter, and the thin flakes cannot pass through the filter, resulting in the accumulation of flaky bamboo and wood debris and clogging the filter. At the same time, the crushing plate 10 is set to an arc shape, so that the crushing plate 10 fits more closely to the inner side of the crushing bin 8, which is easy to push the clumped bamboo and wood debris for crushing operations.

[0045] At the same time, it is considered that bamboo and wood debris are easily stuck in the gaps between the multiple straight plates 7 arranged horizontally, resulting in the gaps between the multiple straight plates 7 being blocked, affecting the passage of fine bamboo and wood debris, resulting in the problem of blockage. Therefore, the hot air is pumped into the gap between the ring plate 208 and the circular plate 5 through the air inlet pipe 3 207 through an external pump, and the hot air enters the spiral plate 6 from the gap between the ring plate 208 and the circular plate 5, and is blown out from the air vent 61 to the gaps between the multiple straight plates 7, so that the hot air blows away the bamboo and wood debris stuck in the gaps between the multiple straight plates 7. This prevents bamboo and wood chips from being easily stuck in the gaps between the multiple straight boards 7 arranged horizontally, causing the gaps between the multiple straight boards 7 to be blocked, thereby affecting the passage of fine bamboo and wood chips. At the same time, when the wet bamboo and wood chips just enter the drying box 1 and come into contact with the straight boards 7, they are easily adhered to the surfaces of the straight boards 7. At this time, hot air is ejected through the air holes 61 to blow off the bamboo and wood chips adhered to the surfaces of the straight boards 7, thereby avoiding the problem of the surfaces of the straight boards 7 being blocked. In addition, the hot air ejected through the air holes 61 can also dry the bamboo and wood chips when the spiral plate 6 pushes the bamboo and wood chips.

[0046] In the process of drying the bamboo and wood chips, although the bamboo and wood chips are dispersed by the stirring of the straight plate 7 and the pushing of the spiral plate 6, considering that the amount of bamboo and wood chips discharged into the drying box 1 is large, the bamboo and wood chips still have a certain degree of accumulation during the drying process, resulting in that when the bamboo and wood chips move to the connection between the drying box 1 and the drying box 2 during the drying process, the dryness of the chips in the bamboo and wood chip pile does not meet the standard and there is still a small amount of moisture. Therefore, when the bamboo and wood chips move to the connection between the drying box 1 and the drying box 2, and When it is located on the air inlet pipe 201, the external pump is controlled to pump hot air into the drying box 1 through the air inlet pipe 201, thereby blowing away the bamboo and wood chips pile moved to the connection between the drying box 1 and the drying box 2, so that the bamboo and wood chips will be transferred with the sucked hot air. The blown bamboo and wood chips are heated and dried by the hot air blown out by the air inlet pipe 201, and are dried by the hot air sucked by the external suction device in the drying box 2, so that the bamboo and wood chips are dried for the second time when they fall into the discharge frame 305, which is beneficial to the drying of the bamboo and wood chips.

[0047] When the hot air ejected from the air inlet pipe 201 blows the bamboo and wood chips upward, the drying box 2 is separated by the guide plate 1 202 to prevent the bamboo and wood chips blown away by the air inlet pipe 201 from being quickly transferred away by the hot air sucked by the external suction device, resulting in a limited secondary drying effect on the bamboo and wood chips. At the same time, the air flow direction blown out from the air inlet pipe 201 is parallel to the guide plate 1 202, and the drying box 2 is separated by the guide plate 1 202, so that the external suction device sucks the hot air in the drying box 1. When hot air is blown, most of the sucked hot air will flow along the guide plate 202. Therefore, when the guide plate 202 separates the drying box 2, the bamboo and wood chips blown away by the air inlet pipe 201 will move along the surface of the guide plate 202, thereby facilitating the secondary drying of the bamboo and wood chips. It should be noted that when the guide plate 202 separates the drying box 2, the hot air sucked by the external suction device will flow through the gap between the guide plate 202 and the drying box 2.

[0048] In addition, when the hot air and bamboo and wood chips move along the guide plate 202, the connecting rod 204 is pushed by the electric push rod 203 to drive the push plate 205 to move back and forth up and down along the surface of the guide plate 202, so that the push plate 205 pushes the bamboo and wood chips moving along the surface of the guide plate 202 up and down, thereby blocking the bamboo and wood chips and enhancing the drying effect. A rough layer 206 is provided on the surface of the guide plate 202. The rough layer 206 is provided to increase the friction between the bamboo and wood chips and the guide plate 202, so as to increase the residence time of the bamboo and wood chips on the guide plate 202.

[0049] Example 2

[0050] On the basis of Example 1, Figure 3 , Figure 7 and Figure 8 As shown, it also includes a pull rope 301, a scraper frame 302 and a spring 303; the scraper frame 302 is slidably connected to the drying box 2, and two connecting shafts are arranged in the drying box 2; two pull ropes 301 are fixedly connected to the connecting rod 204, and each pull rope 301 is wound around the surface of the corresponding connecting shaft and fixedly connected to the upper part of the scraper frame 302, and the scraper frame 302 is in contact with the surface of the filter cloth 304; two springs 303 are fixedly connected to the bottom of the scraper frame 302, and the other ends of all the springs 303 are fixedly connected to the bottom surface of the drying box 2.

[0051] Here is how the above example works:

[0052] When the external suction device sucks hot air from the air outlet 21, some bamboo and wood debris will be adsorbed on the filter cloth 304, so that the bamboo and wood debris will block the filter cloth 304 and affect the circulation of hot air. Therefore, when the electric push rod 203 pulls the connecting rod 204 and the push plate 205, the connecting rod 204 will also pull the pull rope 301 to slide on the surface of the connecting shaft and drive the scraper frame 302 to move upward along the inner surface of the drying box 2, so that the spring 303 is stretched by the scraper frame 302, thereby causing The scraper frame 302 scrapes the surface of the filter cloth 304, so that the bamboo and wood debris are scraped off by the scraper frame 302. When the electric push rod 203 pushes the connecting rod 204 and the push plate 205 to reset, the spring 303 pulls the scraper frame 302 to move downward and reset, so that the scraper frame 302 scrapes the surface of the filter cloth 304 again, further cleaning the surface of the filter cloth 304, thereby improving the cleaning efficiency. At the same time, the bamboo and wood debris scraped off by the scraper frame 302 falls into the discharge frame 305 and is collected by an external collection device.
