Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0037] Embodiment one

[0038] Referring to the drawings shown in the specification: Figures 1-4

[0039] An integrated straw board raw material pretreatment and production device, comprising:

[0040] ​The double-shaft shearing shredder 700 is used for receiving intermittent feed of straw and separating the straw, and comprises a transmission structure, a double-blade system and a machine box. Opposite feed and discharge ports are arranged at the upper and lower ends of the machine box. The transmission structure comprises a motor and a coupling. The machine box is used for receiving baled straw, and the transmission structure drives the blade system to rotate at high speed to shred the straw and form segmented straw. The double-blade system comprises two groups of parallel blade units, namely blade unit one and blade unit two. The blade unit comprises a blade and a moving cutter. The moving cutter is the core part of the shredder and comprises a main shaft, a blade and a bearing. The motor is connected with the coupling to provide power for the shredder. The coupling drives the main shaft to rotate, thereby driving the blade system to rotate at high speed to shred the material. The fixed cutter and the moving cutter cooperate with each other to further shred the material by shearing force, and form segmented straw. The main shaft of the blade unit one penetrates through one end of the machine box and is connected with the transmission structure. The other end is fixed with a driving gear one 710. The main shaft of the blade unit two penetrates through both ends of the machine box and is fixed with a driving gear two 720. The driving gear one 710 and the driving gear two 720 are in meshing transmission.

[0041] The drying conveying pipeline 400 is designed in the form of a bent pipeline and is welded to the discharge port of the machine box to ensure that the shredded straw can smoothly enter. A funnel-shaped connecting cylinder is arranged between the drying conveying pipeline 400 and the machine box to concentrate the segmented straw, so that the segmented straw can smoothly enter the inside of the drying conveying pipeline 400. A hammer crusher 300 is fixedly connected to the other end of the drying conveying pipeline 400. The hammer crusher 300 is used for drying and crushing the straw.

[0042] In order to further improve the automation level of the equipment, a turnover unloading module 500 is innovatively introduced into the inside of the drying conveying pipeline 400. The turnover unloading module 500 is rotatably installed in the inside of the drying conveying pipeline 400, and an external driving device 600 is installed outside the machine box of the drying conveying pipeline 400. The turnover unloading module 500 can be driven by the external driving device 600 to rotate slowly, intermittently seal the drying conveying pipeline 400, and realize intermittent unloading of the segmented straw in the turnover, so that the straw raw material further falls to the hammer crusher 300 to be crushed into the required granular material for board making.

[0043] Specifically, the turnover unloading module 500 is composed of two groups of rotating structures 510, and a driving belt 520 is arranged between the two groups of rotating structures 510 and is synchronously driven through the driving belt 520. The two groups of turnover unloading modules 500 are respectively rotationally installed at the two ends of the drying conveying pipeline 400, and synchronous rotation of the two groups of rotating structures 510 realizes sealing of the drying conveying pipeline 400, so that the inner cavity of the drying conveying pipeline 400 forms a sealed chamber.

[0044] Specifically, the rotating structure 510 comprises a rotating valve one and two groups of linkage gear sets 511, and the two groups of linkage gear sets 511 are respectively in meshing transmission with the driving gear two 720 and the driving gear one 710. The rotating valve one comprises a rotating roller one 513 penetrating through the drying conveying pipeline 400 and a rotating plate one 512 fixed to the surface of the 530. The rotating structure 510 is provided with a controller on the surface of the rotating roller one 513, which is used to control the rotation angle of the two groups of rotating structures 510. When the rotating structure 510 is in a stationary state, the controller adjusts the angle so that it is always in the state of sealing the drying conveying pipeline 400. When the section-shaped straw enters the double-shaft shearing shredder 700, the double-blade system of the double-shaft shearing shredder 700 rotates at high speed to shred the material, the bundled straw forms a section-shaped straw, and the section-shaped straw is discharged from the discharge port of the double-shaft shearing shredder 700. The section-shaped straw enters the inner cavity of the drying conveying pipeline 400 through the connecting cylinder. The two groups of linkage gear sets 511 are respectively linkage gear one and linkage gear two. The external driving device 600 drives the rotating plate one 512 to rotate through the linkage gear one.

[0045] Meanwhile, the external driving device 600 comprises two groups of transmission units, which are respectively located at the two sides of the drying conveying pipeline 400 and are in meshing with the two groups of driving gear two 720 at the two ends of the main shaft of the blade unit two. The two groups of transmission units are respectively transmission unit one and transmission unit two. The transmission structure is in meshing transmission with the turnover unloading module 500 through the driving gear two 720 and the transmission unit one, so as to realize accurate control of the turnover unloading. The transmission unit one and the transmission unit two are consistent in structure. The transmission unit comprises a cast iron gear 610 fixed to the cabinet and two groups of cast steel gears 630 fixed to the outer wall of the connecting cylinder. A group of synchronous belts 620 is arranged between the two groups of cast steel gears 630, and the transmission between the two groups of cast steel gears 630 is realized through the synchronous belts 620. The cast iron gear 610 is in meshing with the driving gear two 720, and the meshing ratio is 5:1. The meshing ratio of the cast iron gear 610 and the group of cast steel gears 630 is 2:1. The other group of cast steel gears 630 is in meshing with the linkage gear one, and the meshing ratio is 2:1. Through the change of the meshing ratio, the turnover unloading module 500 is in slow rotation. When a certain amount of section-shaped straw is accumulated on the surface of the rotating plate one 512, the turnover unloading is realized.

[0046] In actual design, according to the time and the amount of intermittent incoming of the straw, the engagement ratio of the cast iron gear 610 and the driving gear two 720, the cast iron gear 610 and the cast steel gear 630, and the cast steel gear 630 and the turnover and unloading module 500 is changed, the tearing efficiency of the straw is changed, and the segmental straw is unloaded in batches in the form of intermittent turnover of the rotating plate one 512, the segmental straw is dried and crushed in multiple and small amounts, the tearing and drying efficiency of the straw is ensured, and the quality of the straw product is ensured.

[0047] Embodiment two

[0048] Referring to the drawings attached Figures 3-8 in the specification:

[0049] The hot air introduction system 200 is communicated with the middle position of the drying conveying pipeline 400. In order to enhance the drying effect, the hot air introduction system 200 is introduced at the middle position of the drying conveying pipeline 400. The system can uniformly introduce hot air into the inner cavity of the drying conveying pipeline 400, so as to realize rapid drying of the straw. Specifically, the hot air introduction system 200 includes a combustion device, a heat exchanger, a fan, an air supply pipeline and a control system. The combustion device is responsible for burning fuel to generate heat energy, and the heat energy generated by combustion is transferred to air through the heat exchanger to heat the air to form hot air, and the fan drives the hot air to flow and sends it into the air supply pipeline. The control system monitors and adjusts the operating state of the whole system, including temperature, wind speed and other parameters. The above is the prior art. The ventilation pipeline is connected to the adapter, and the surface of the adapter connecting head 210 is additionally provided with a plurality of extension hoses 220. The plurality of extension hoses 220 are communicated with the surface of the 440. The number of the extension hoses 220 is not less than three groups. The three groups of extension hoses 220 pass the hot air into the inner cavity of the drying conveying pipeline 400 at different angles to ensure the uniformity of the hot air of the drying conveying pipeline 400.

[0050] In order to further improve the automation level of the equipment, the turnover module 800 is innovatively introduced into the inside of the drying conveying pipeline 400. The turnover module 800 is rotatably installed in the inside of the drying conveying pipeline 400. The external driving device 600 is installed outside the case of the drying conveying pipeline 400. The external driving device 600 drives the turnover module 800 to rotate quickly, turns over the segmental straw in the turnover, uniformly dries the straw, and ensures that the moisture content of each part of the straw is consistent.

[0051] The two sets of linkage gear sets 511 are linkage gear one and linkage gear two, respectively. The external driving device 600 drives the turning module 800 to rotate through the linkage gear two. The linkage gear one is fixed to one end of the roller one 513, and the linkage gear two is rotatably installed at the other end of the roller one 513. The turning module 800 includes an upper turning part 810 and a lower turning part 820. The upper turning part 810 is rotatably arranged in meshing with the linkage gear two. The upper turning part 810 and the lower turning part 820 are arranged in meshing transmission.

[0052] The transmission structure is arranged in meshing transmission with the turning and discharging module 500 and the turning module 800 through the driving gear two 720, the transmission unit two, so as to realize precise control of the turning module 800. The transmission unit one and the transmission unit two are consistent in structure, but the gear rack and gear size of the gear surface are inconsistent. The cast iron gear 610 in the transmission unit two is in meshing with the driving gear two 720. The meshing ratio is 1:2. The meshing ratio of the cast iron gear 610 and the group of cast steel gears 630 is 1:2. The meshing ratio of the other group of cast steel gears 630 and the linkage gear two is 1:5. The meshing ratio of the linkage gear two and the turning module 800 is 1:5. The turning module 800 is in rapid rotation. The turning module 800 in rapid rotation turns the bunched segment type straw, so that the segment type straw is separated. After the hot air rapidly passes through the straw, the straw is uniformly dried, the drying efficiency of the straw is improved, and the moisture content of the straw is more uniform.

[0053] The slow rotation of the turning and discharging module 500 of the device is used for discharging the blocked straw in the drying conveying pipeline 400, increasing the contact time of the hot air and the straw, and improving the efficiency of the hot air drying.

[0054] The upper turning part 810 includes a rotating valve two and two groups of rotating gears. The rotating valve two includes a roller two penetrating the drying conveying pipeline 400 and a rotating plate two fixed to the surface of the roller two. In the rotating process of the rotating plate two, the straw is turned, and the hot air in the drying conveying pipeline 400 is rapidly and uniformly distributed.

[0055] The device fully considers the linkage and operation convenience in design. For example, the main shaft of the blade unit one is connected with the motor through the transmission structure, and the main shaft of the blade unit two is arranged in meshing transmission with the transmission unit through the two groups of driving gears two 720. This design not only improves the overall operation efficiency of the device, but also reduces the maintenance cost.

[0056] The turning and discharging module and the turning module 800 part of the turning module in the device also adopt a unique rotating valve and rotating gear design, and the rotating angle thereof is precisely controlled through the controller, so as to further improve the automation level of the device.

[0059] The surface of the hammer mill 300 is provided with a feed inlet and a discharge outlet, and the drying conveying pipeline 400 is welded to the feed inlet of the surface of the hammer mill 300. When the turnover unloading module 500 unloads the preliminarily dried sectioned straw into the hammer mill 300, the hammer mill 300 crushes the sectioned straw. A removable grid for filtering is installed at the discharge outlet of the hammer mill 300 to filter the dried straw and ensure the purity of the final product. In addition, in the process of unloading the sectioned straw, hot air enters the inner cavity of the hammer mill 300 together with the sectioned straw. After the hammer mill 300 crushes the sectioned straw into granular straw, the heat continuously flows through the surface of the straw, further drying the straw, achieving secondary drying of the straw, improving the utilization efficiency of heat, and realizing the recycling of heat.

[0060] In addition, during the operation of the inner cavity of the hammer mill 300, the broken straw will generate a lot of dust. Due to the pressure difference, the dust will enter the inner cavity of the drying conveying pipeline 400 and then upsurge into the inner cavity of the double-shaft shearing shredder 700. The dust entering the transmission structure will cause failure of the double-shaft shearing shredder 700 and reduce the service life of the double-shaft shearing shredder 700. By adding the turnover unloading module 500 and the turning module 800, intermittent unloading can be realized, and the hammer mill 300, the hot air introduction system 200, and the double-shaft shearing shredder 700 can work independently without interfering with each other.

[0062] The double-shaft shearing shredder 700 and the hammer mill 300 are further provided with a rack 100 for size, wherein the rack 100 comprises a support frame one 110, a support frame two 120, a connecting plate 130 and a support frame three 140, the support frame one 110 is used for supporting the double-shaft shearing shredder 700, the support frame two 120 is used for supporting the double-shaft shearing shredder 700, the support frame one 110 is used for supporting the hot air introduction system 200, and the support frame one 110, the support frame two 120 and the support frame three 140 are connected into an integrated whole through the connecting plate 130.
