Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metering silos, in particular to a double-section metering silo device. BACKGROUND

[0002] Particle board, also known as micro-particle board, granular board, and bagasse board, is a kind of man-made board made of wood or other lignocellulosic materials, which is glued under the action of heat and pressure after applying adhesive. OSB board is a kind of directional structure board made of small-diameter timber, intermediate timber, and wood core as raw materials, which is processed into long shavings by special equipment, and then made into a directional structure board through processes such as oil removal, drying, glue application, directional laying, and hot pressing.

[0003] In the process of producing OSB board, a metering silo is needed to transport the dried material to the glue mixer for gluing. However, the existing metering silo uses a belt conveyor to transport the material (such as the Chinese utility model patent No. 202021867931.9 discloses a particle board core metering silo), and it is difficult to avoid that some materials will agglomerate together (i.e., clumping) in the actual production process. The existing metering silo cannot effectively disperse the clumped material, which makes it difficult to accurately measure the material, thereby affecting the quality of the finished product. In view of the above problems, the present application is produced after the inventor has conducted in-depth research on the problem. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a double-section metering silo device to solve the problem that the existing metering silo cannot accurately measure the material, thereby affecting the quality of the finished product.

[0006] The silo body has a first silo section and a second silo section, and the first silo section and the second silo section are connected to each other through a material falling channel. The top of the first silo section is provided with a material inlet opening, and the second silo section is provided with a material outlet opening at the end away from the first silo section;

[0007] The belt conveyor includes a first belt conveying assembly arranged in the first silo section and a second belt conveying assembly arranged in the second silo section. The conveying speed of the second belt conveying assembly is greater than that of the first belt conveying assembly. The second belt conveying assembly is arranged at a lower position than the first belt conveying assembly, and the second belt conveying assembly is provided with a first weighing sensor;

[0008] The sweeping mechanism and the throwing mechanism are arranged in the first hopper section, the throwing mechanism is located above the output end of the first belt conveying assembly, and the sweeping mechanism is located between the feeding opening and the first belt conveying assembly.

[0009] Further, the conveying speed of the second belt conveying assembly is 10-15 times the conveying speed of the first belt conveying assembly.

[0010] Further, the throwing mechanism comprises a plurality of throwing rollers arranged in the first hopper section from top to bottom along the conveying direction of the material, the rotation centers of the throwing rollers are located on the same oblique line, and the throwing channels connected with the feeding channels are formed between each of the throwing rollers and the top of the first hopper section, and a gap is left between the lowermost throwing roller and the first belt conveying assembly, and one end of each of the throwing rollers is connected with a first driving mechanism; the uppermost throwing roller rotates counterclockwise, and the remaining throwing rollers rotate clockwise.

[0011] Further, each of the throwing rollers comprises a rotating shaft body and a plurality of throwing plates fixed on the rotating shaft body at equal intervals, each of the throwing plates is provided with a plurality of throwing blocks around the throwing plate, the upper end of each of the throwing blocks is provided with a hooking part extending in the rotating direction, and the throwing blocks of each of the throwing plates on the rotating shaft body are distributed in a spiral manner.

[0012] Further, the included angle between the oblique line and the horizontal line is 40°-50°.

[0013] Further, the top of the second hopper section is higher than the top of the first belt conveying assembly, and the top of the second hopper section is lower than the top of the lowermost throwing roller.

[0014] Further, the sweeping mechanism comprises a driving sprocket, a driven sprocket, a transmission chain, a support rod, a sweeping rod, and a second driving mechanism; the driving sprocket and the driven sprocket are rotatably arranged on the inner side wall of the first hopper section, the transmission chain is sleeved on the driving sprocket and the driven sprocket, the second driving mechanism is fixed on the outside of the first hopper section, and the second driving mechanism is connected with the driving sprocket; a plurality of bent plates are arranged at equal intervals on the transmission chain, each of the bent plates is fixedly connected with a support rod, and the support rod is perpendicular to the inner side wall of the first hopper section; each of the support rods is fixedly provided with a row of sweeping rods along the length direction.

[0015] Further, the height difference between the top of the first belt conveying assembly and the top of the second belt conveying assembly is 30cm-40cm.

[0016] Further, the first belt conveying assembly is provided with a second weighing sensor.

[0017] Further, the top of the bin body is provided with an explosion-proof window, a dust suction port and a fire-fighting water interface, and the sidewall of the bin body is provided with an observation window.

[0018] By adopting the technical scheme of the present application, at least the following beneficial effects are achieved:

[0019] 1. The bin body has a first bin section and a second bin section, and a first belt conveying assembly with a second weighing sensor is arranged in the first bin section, and a second belt conveying assembly with a first weighing sensor is arranged in the second bin section, so that in specific use, the second weighing sensor can be used to preliminarily weigh the material, and whether the material in the first bin section is sufficient can be judged according to the weighing result of the second weighing sensor, so that the material can be supplemented into the first bin section in time when the material is insufficient; meanwhile, the material can be weighed again by the first weighing sensor after entering the second belt conveying assembly; through this double-time weighing mode, more accurate weighing and metering of the material can be realized, thereby realizing quantitative and continuous feeding of the rubber mixing machine.

[0020] 2. A throwing mechanism is arranged above the output end of the first belt conveying assembly, and when the first belt conveying assembly conveys the material to the position of the throwing mechanism, the throwing mechanism can throw the material forward, so that the agglomerated and caked material is loosened, thereby enabling the rubber mixing machine to apply glue to the material more uniformly.

[0021] 3. The second belt conveying assembly is designed to be arranged at a position lower than the first belt conveying assembly, so that a height difference is formed between the second belt conveying assembly and the first belt conveying assembly, and thus the material output by the first belt conveying assembly will fall downward under the action of gravity, which is beneficial to better loosening of the material and ensures that the material conveyed to the rubber mixing machine will not have the phenomenon of agglomeration and caking, which helps to improve the uniformity of glue application to the material and avoids causing relatively large impact on the rubber mixing machine; meanwhile, the conveying speed of the second belt conveying assembly is designed to be greater than that of the first belt conveying assembly, so that in specific work, when the material output by the first belt conveying assembly falls downward to the second belt conveying assembly, the second belt conveying assembly can rapidly convey the material forward, and the material will not be accumulated at the input end of the second belt conveying assembly.

[0022] 4. A sweeping mechanism is arranged between the feeding opening and the first belt conveying assembly, and in the process of conveying the material forward by the first belt conveying assembly, the sweeping mechanism can sweep the top of the material, so that the material can be more uniformly distributed on the first belt conveying assembly, thereby being beneficial to more accurate weighing, and the sweeping mechanism can also play a role in dispersing the material on the top.

[0023] 5. During the entire metering process, the material will first be leveled by the leveling mechanism and weighed by the second weighing sensor, then scattered by the scattering mechanism and fall down through the height difference formed between the second belt conveyor assembly and the first belt conveyor assembly, and finally weighed again by the first weighing sensor, and quickly transported to the glue mixer by the second belt conveyor assembly. The combination of the above multiple processes can not only effectively improve the accuracy of material measurement, but also ensure that the material transported to the glue mixer is loose without agglomeration or caking, thereby effectively improving the gluing effect and the quality of the finished product.

[0024] 6. The scattering blocks of each throwing plate are arranged on the rotating shaft body in a spiral manner, and the upper end of each throwing block is provided with a hook part facing the rotation direction, so that during specific operation, the spirally distributed throwing plates can make the material produce a spiral effect, and the hook part can hook the material, thereby having a good effect of throwing and breaking up the material.

[0025] 7. Placing the bearing support and bearing outside the first silo section can effectively prevent materials from entering the interior of the bearing, thereby preventing the spreading roller from being unable to rotate normally due to material jamming during operation, and also helps to increase the service life of the bearing.

[0026] 8. A wear-resistant plate is fixedly installed at the position corresponding to the rotating shaft body on the first silo section, and both ends of the rotating shaft body pass through the wear-resistant plate. Since the wear-resistant plate has wear-resistant properties, it can avoid excessive gap between the rotating shaft body and the first silo section due to wear, thereby ensuring the working stability of the spreading roller.

[0027] 9. By setting a limiting guide rail on the inner wall of the first silo section, forming a limiting groove on the top of the limiting guide rail, and placing the upper part of the transmission chain in the limiting groove, during specific operation, the limiting groove can be used to limit the upper part of the transmission chain, ensuring that the transmission chain will not swing and disengage from the driving sprocket or the driven sprocket, thereby improving the stability of the transmission chain during operation.

[0028] 10. Wear-resistant plastic plates are installed at positions that may collide or rub with the transmission chain, which can effectively prevent the transmission chain from catching fire due to collision or friction during the production process, thereby ensuring production safety; at the same time, the setting of the first baffle and the second baffle can also prevent materials from falling directly into the transmission chain, so that the transmission chain will not be unable to transmit normally due to material jamming.

[0051] The bin body 1 has a first bin section 11 and a second bin section 12, and the first bin section 11 and the second bin section 12 are connected to each other through a material falling channel 13, so that the materials in the first bin section 11 can enter the second bin section 12 through the material falling channel 13, and the first bin section 11 is provided with a material inlet opening 14 at the top, and the materials required for the production of particle board are conveyed into the first bin section 11 through the material inlet opening 14, and the second bin section 12 is provided with a material outlet opening 15 at the end away from the first bin section 11, and the metered materials can be output through the material outlet opening 15;

[0052] The belt conveyor 4 comprises a first belt conveying assembly 41 arranged in the first silo section 11 and a second belt conveying assembly 42 arranged in the second silo section 12, the conveying speed of the second belt conveying assembly 42 is greater than that of the first belt conveying assembly 41, so as to avoid material accumulation at the input end position of the second belt conveying assembly 42, the second belt conveying assembly 42 is arranged at a position lower than the first belt conveying assembly 41, so that there is a height difference between the second belt conveying assembly 42 and the first belt conveying assembly 41, the material output by the first belt conveying assembly 41 falls downward onto the second belt conveying assembly 42, the first belt conveying assembly 41 is provided with a first weighing sensor 43, which can be used to weigh the material conveyed on the second belt conveying assembly 42 during work; more specifically, the first belt conveying assembly 41 is provided with a second weighing sensor 44, which can preliminarily weigh the material on the first belt conveying assembly 41, and can determine whether the material in the first silo section 11 is sufficient according to the weighing result of the second weighing sensor 44, if the material in the first silo section 11 is insufficient, the material can be supplemented into the first silo section 11;

[0053] The sweeping mechanism 2 and the throwing mechanism 3 are both arranged in the first silo section 11, the throwing mechanism 3 is located above the output end of the first belt conveying assembly 41, so as to throw the material at the output end of the first belt conveying assembly 41 forward by the throwing mechanism 3, so that the agglomerated and caked material is better dispersed; the sweeping mechanism 2 is located between the feeding opening 14 and the first belt conveying assembly 41, the material required for the production of the particle board is conveyed into the first silo section 11 through the feeding opening 14, and falls downward onto the first belt conveying assembly 41, and then the top of the material can be swept by the sweeping mechanism 2, and the sweeping mechanism 2 can also play a role in dispersing the material on the top.

[0054] The double-section metering silo device 100 of the present application can be used for more accurate weighing and metering of OSB material and the like, and the specific working principle is as follows:

[0055] The material (such as OSB material) required for the production of the shaving board is conveyed into the first bin section 11 through the feeding opening 14, and the material falls onto the first belt conveying assembly 41 under the action of gravity; after the material falls onto the first belt conveying assembly 41, the material is conveyed forward through the first belt conveying assembly 41, and in this process, the second weighing sensor 44 on the first belt conveying assembly 41 can preliminarily weigh the material, and if the second weighing sensor 44 finds that the material in the first bin section 11 is insufficient after weighing, the material can be supplemented into the first bin section 11 through the feeding opening 14; at the same time, in the process of conveying the material forward by the first belt conveying assembly 41, the leveling mechanism 2 can level the top of the material, so that the material can be more evenly distributed on the first belt conveying assembly 41, thereby facilitating more accurate weighing.

[0056] When the first belt conveying assembly 41 conveys the material to the position of the throwing mechanism 3, the throwing mechanism 3 can throw the material forward, and the thrown material falls into the second bin section 12 through the material falling channel 13; in the process of throwing the material forward and making the material fall through the material falling channel 13, the throwing mechanism 3 can effectively scatter the agglomerated and caked material, thereby ensuring that the material entering the second bin section 12 is loose, which is conducive to more accurate metering of the material by the first weighing sensor 43 on the second belt conveying assembly 42, and also conducive to more uniform sizing of the material by the glue mixer, thereby ensuring the quality of the produced finished product. After the material falls onto the second belt conveying assembly 42 in the second bin section 12, the second belt conveying assembly 42 can continue to convey the material forward and output the material to the glue mixer through the discharge opening 15 on the second bin section 12; in this process, the first weighing sensor 43 on the second belt conveying assembly 42 can weigh the material to realize quantitative and continuous feeding of the glue mixer.

[0057] By adopting the technical scheme of the present application, at least the following beneficial effects are achieved:

[0058] 1. The bin body 1 has the first bin section 11 and the second bin section 12, and the first belt conveying assembly 41 with the second weighing sensor 44 is arranged in the first bin section 11, and the second belt conveying assembly 42 with the first weighing sensor 43 is arranged in the second bin section 12, so that in specific use, the second weighing sensor 44 can preliminarily weigh the material, and the weighing result of the second weighing sensor 44 can be used to judge whether the material in the first bin section 11 is sufficient, so that the material can be supplemented into the first bin section 11 in time when the material is insufficient; at the same time, the first weighing sensor 43 can weigh the material again after the material enters the second belt conveying assembly 42; by this double weighing and twice weighing mode, more accurate weighing and metering of the material can be realized, thereby realizing quantitative and continuous feeding of the glue mixer.

[0059] 2. A throwing mechanism 3 is arranged above the output end of the first belt conveying assembly 41, and when the first belt conveying assembly 41 conveys the material to the position of the throwing mechanism 3, the throwing mechanism 3 can throw the material forward to loosen the agglomerated and caked material, so that the rubber mixing machine can uniformly coat the material.

[0060] 3. The second belt conveying assembly 42 is arranged at a position lower than the first belt conveying assembly 41, so that a height difference is formed between the second belt conveying assembly 42 and the first belt conveying assembly 41, and the material output by the first belt conveying assembly 41 falls down under the action of gravity, which is beneficial to better loosen the material and ensure that the material conveyed to the rubber mixing machine is not agglomerated and caked, which helps to improve the uniformity of material coating and avoid a relatively large impact on the rubber mixing machine; meanwhile, the conveying speed of the second belt conveying assembly 42 is greater than that of the first belt conveying assembly 41, so that when the material output by the first belt conveying assembly 41 falls down to the second belt conveying assembly 42, the second belt conveying assembly 42 can quickly convey the material forward, and the material will not be accumulated at the input end of the second belt conveying assembly 42.

[0061] 4. A flattening mechanism 2 is arranged between the feeding opening 14 and the first belt conveying assembly 41, and in the process of conveying the material forward by the first belt conveying assembly 41, the flattening mechanism 2 can flatten the top of the material, so that the material can be more uniformly distributed on the first belt conveying assembly 41, which is beneficial to more accurate weighing, and the flattening mechanism 2 can also play a role in dispersing the material on the top.

[0062] 5. In the whole metering process, the material will first be flattened by the flattening mechanism 2 and weighed by the second weighing sensor 44, then be thrown by the throwing mechanism 3 and fall down through the height difference formed between the second belt conveying assembly 42 and the first belt conveying assembly 41, and finally be weighed again by the first weighing sensor 43 and quickly conveyed to the rubber mixing machine by the second belt conveying assembly 42, through the combination of the above multiple processes, the accuracy of material metering can be effectively improved, and the material conveyed to the rubber mixing machine is loose and will not be agglomerated and caked, so as to effectively improve the coating effect and the quality of finished products.

[0063] In the preferred embodiment of the present application, the conveying speed of the second belt conveying assembly 42 is 10-15 times that of the first belt conveying assembly 41, so as to ensure that the second belt conveying assembly 42 can quickly output the material and ensure that the material will not be accumulated at the input end of the second belt conveying assembly 42.

[0064] As a specific embodiment of the present invention, please refer to Figures 8-11 As shown, the scattering mechanism 3 includes a plurality of scattering rollers 31 arranged in the first silo section 11 and rotating from top to bottom along the conveying direction of the material, and the rotation center of each scattering roller 31 is on the same oblique line, that is, along the conveying direction of the material, the latter scattering roller 31 is located at a position lower than the previous scattering roller 31, and each scattering roller 31 needs to be set at a distance to ensure that each scattering roller 31 can work independently without affecting each other; a scattering channel 16 connected to the blanking channel 13 is formed between each scattering roller 31 and the top of the first silo section 11, and the material scattering by the scattering roller 31 during operation can enter the blanking channel 13 through the scattering channel 16, and then The material falls downward through the blanking channel 13 into the second silo section 12. A gap is left between the lowest scattering roller 31 and the first belt conveyor assembly 41 to ensure that the scattering roller 31 does not affect the operation of the first belt conveyor assembly 41. One end of each scattering roller 31 is connected to a first drive mechanism 32 to drive the scattering roller 31 to rotate using the first drive mechanism 32. Preferably, the first drive mechanism 32 adopts a reduction motor; the top scattering roller 31 rotates counterclockwise, and the top scattering roller 31 can play a dual role of scattering materials and calling materials back. The remaining scattering rollers 31 all rotate clockwise, and the remaining scattering rollers 31 mainly play a role of scattering materials forward.

[0065] The present invention is designed such that the scattering mechanism 3 includes a plurality of scattering rollers 31 arranged in the first silo section 11 and rotating from top to bottom along the conveying direction of the material. The rotation centers of the scattering rollers 31 are on the same oblique line, and the scattering roller 2 located at the top rotates counterclockwise, while the remaining scattering rollers 2 rotate clockwise. In specific operation, the scattering mechanism 3 can effectively break up the agglomerated and lumped materials and can also play a role in repelling the materials on the top, thereby achieving a leveling effect.

[0066] More specifically, each of the throwing rollers 31 comprises a rotating shaft body 311 and a plurality of throwing plates 312 fixed on the rotating shaft body 311 at equal intervals, each of the throwing plates 312 is provided with a plurality of throwing blocks 3121 around the periphery, the upper end of each of the throwing blocks 3121 is provided with a hooking part 3122 extending in the rotating direction, and the throwing blocks 3121 of each of the throwing plates 312 on the rotating shaft body 311 are distributed in a spiral manner, the first driving mechanism 32 is connected to one end of the rotating shaft body 311, so as to drive the rotating shaft body 311 to rotate by the first driving mechanism 32, thereby driving each of the throwing plates 312 to rotate together, so that each of the throwing plates 312 can play a throwing effect on the material. In the present application, the throwing blocks 3121 of each of the throwing plates 312 are arranged on the rotating shaft body 311 in a spiral manner, and the upper end of each of the throwing blocks 3121 is provided with a hooking part 3122 extending in the rotating direction, so that in the specific work, the spiral distributed throwing plates 312 can produce a spiral effect on the material, and the hooking part 3122 can hook up the material, thereby playing a good throwing and scattering effect on the material.

[0067] More specifically, the throwing plates 312 are provided with the throwing blocks 3121 which are inclined to both sides along the axial direction, specifically, the throwing blocks 3121 can be slightly bent along the axial direction, so that the throwing blocks 3121 are slightly inclined to the left or right along the axial direction, and the throwing blocks 3121 on the adjacent two throwing plates 312 do not interfere with each other, that is, a gap is reserved between the throwing blocks 3121 on the adjacent two throwing plates 312, thereby ensuring that the throwing blocks 3121 on the adjacent two throwing plates 312 do not collide with each other during work. Since the material may be stuck between the adjacent two throwing plates 312 during specific implementation, the present application is designed to have the throwing blocks 3121 inclined to both sides along the axial direction on the throwing plates 312, which can facilitate throwing the material between the two throwing plates 312, thereby improving the throwing range and throwing effect of a single throwing plate 312.

[0068] More specifically, the outside of the first bin section 11 is provided with a bearing support 33 corresponding to the position of each end of the rotating shaft body 311, and a bearing (not shown) is arranged in each of the bearing supports 33, and the two ends of the rotating shaft body 311 are connected with the bearings, thereby ensuring that the rotating shaft body 311 can rotate under the driving of the first driving mechanism 32. Since the bearing is directly arranged on the first bin section 11, the material may be stuck in the inside of the bearing during work, thereby causing the throwing roller 31 to be unable to rotate normally; therefore, the bearing support 33 and the bearing are arranged outside the first bin section 11 in the present application, which can effectively prevent the material from entering the inside of the bearing, thereby preventing the throwing roller 31 from being unable to rotate normally due to material sticking during work, and also helping to improve the service life of the bearing.

[0069] More specifically, the first bin section 11 is provided with wear plates 34 corresponding to each of the shaft bodies 311, and the two ends of the shaft body 311 pass through the wear plate 34. Since the bearing support 33 and the bearing are arranged outside the first bin section 11, there is inevitable rotational friction between the shaft body 311 and the first bin section 11. After a long time of work, a large gap will exist between the shaft body 311 and the first bin section 11 due to wear, which will affect the stability of the throwing roller 31. Therefore, the wear plate 34 is arranged on the first bin section 11 corresponding to the position of the shaft body 311, and the two ends of the shaft body 311 pass through the wear plate 34. Since the wear plate 34 has wear-resistant properties, it can avoid a large gap between the shaft body 311 and the first bin section 11 due to wear, thereby ensuring the stability of the throwing roller 31. More specifically, the wear plate 34 is made of plastic, so that the shaft body 311 and the wear plate 34 will not catch fire due to friction, thereby ensuring production safety.

[0070] More specifically, in order to better realize the throwing of the material, the angle α between the inclined line and the horizontal line is 40°-50°. Preferably, the angle α between the inclined line and the horizontal line is 45°.

[0071] More specifically, the periphery of each of the throwing plates 312 is provided with four throwing blocks 3121 at equal intervals, so as to better throw the material. Of course, the present application is not limited thereto, and the number of the throwing blocks 3121 can be increased or decreased according to actual needs in specific implementation.

[0072] More specifically, in order to more uniformly throw the material, a plurality of the throwing plates 312 are fixed on the shaft body 311 at equal intervals, and the interval between adjacent two of the throwing plates 312 is 18mm-22mm. Preferably, the interval between adjacent two of the throwing plates 312 is 20mm.

[0073] More specifically, the first bin section 11 is provided with five throwing rollers 31 arranged from top to bottom along the conveying direction of the material. Specifically, the five throwing rollers 31 can be arranged at equal intervals along the conveying direction of the material. In work, the uppermost throwing roller 31 rotates counterclockwise to push the material at the top back, and the lower four throwing rollers 31 all rotate clockwise to well throw the material forward.

[0074] In the preferred embodiment of the present application, the top of the second bin section 12 is higher than the top of the first belt conveying assembly 41, and the top of the second bin section 12 is lower than the top of the lowermost throwing roller 31. In the specific implementation of the present application, the size of the second bin section 12 is smaller than the size of the first bin section 11, which is conducive to the more accurate metering of the material in the second bin section 12 by the first weighing sensor 43.

[0075] As a specific embodiment of the present application, please refer to Figure 3 and Figure 4 As shown in the drawings, the leveling mechanism 2 comprises a driving sprocket 21, a driven sprocket 22, a transmission chain 23, a support rod 24, a leveling rod 25, and a second driving mechanism 26. The driving sprocket 21 and the driven sprocket 22 are both rotationally arranged on the inner side wall of the first bin section 11. The transmission chain 23 is sleeved on the driving sprocket 21 and the driven sprocket 22. The second driving mechanism 26 is fixed outside the first bin section 11, and the second driving mechanism 26 is connected with the driving sprocket 21, so as to drive the driving sprocket 21 to drive the transmission chain 23 to transmit. Preferably, the second driving mechanism 26 can adopt a speed reducer. A plurality of bent plates 231 are arranged at intervals on the transmission chain 23. Each bent plate 231 is fixedly connected with a support rod 24. The support rod 24 is perpendicular to the inner side wall of the first bin section 11. Each support rod 24 is fixed with a row of leveling rods 25 along the length direction. In order to achieve better leveling effect, the leveling rods 25 on adjacent two support rods 24 can be arranged staggered.

[0076] In the specific work of the leveling mechanism 2, the second driving mechanism 26 drives the driving sprocket 21 to drive the transmission chain 23 to transmit. The transmission chain 23 drives the support rod 24 and the leveling rod 25 to move together in the transmission process, so that each leveling rod 25 can level the top of the material.

[0077] In the specific work, the transmission chain 23 can drive each support rod 24 and leveling rod 25 to move together, so that the material can be continuously leveled backward, and the material is more evenly distributed in the first bin section 11, which is conducive to more accurate metering of the material. Moreover, the structure of using the transmission chain 23 to drive each support rod 24 and leveling rod 25 to move together for leveling can be well applied to the leveling of OSB material.

[0078] More specifically, the inner side wall of the first bin section 11 is provided with a limiting guide rail 51 at a position corresponding to the upper half of the transmission chain 23, the top of the limiting guide rail 51 is recessed downward to form a limiting groove 511, and the upper half of the transmission chain 23 is arranged in the limiting groove 511 to limit the transmission chain 23. Because the transmission chain 23 is relatively long and prone to swing during actual work, which may cause the transmission chain 23 to disengage from the driving sprocket 21 or the driven sprocket 22. Therefore, the limiting guide rail 51 is arranged on the inner side wall of the first bin section 11, the limiting groove 511 is formed on the top of the limiting guide rail 51, and the upper half of the transmission chain 23 is arranged in the limiting groove 511, so that the limiting groove 511 can limit the upper half of the transmission chain 23 during actual work, preventing the transmission chain 23 from swinging and disengaging from the driving sprocket 21 or the driven sprocket 22, and improving the stability of the transmission chain 23 during work.

[0079] More specifically, the top surface of the limiting guide rail 51 and the groove wall of the limiting groove 511 are both provided with a first wear-resistant plastic plate 52; the inner side wall of the first bin section 11 is provided with a support bar 53 at a position corresponding to the lower half of the transmission chain 23, the top surface of the support bar 53 is fixedly provided with a second wear-resistant plastic plate 54, and the lower half of the transmission chain 23 is located directly above the second wear-resistant plastic plate 54; the inner side wall of the first bin section 11 is fixedly provided with a third wear-resistant plastic plate (not shown) at a position corresponding to the side of the transmission chain 23; the inner side wall of the first bin section 11 is fixedly provided with a first baffle 55 located above the upper half of the transmission chain 23 and a second baffle 56 located above the lower half of the transmission chain 23, and both the first baffle 55 and the second baffle 56 are wear-resistant plastic plates. Because the transmission chain 23 is prone to jump during actual work and may collide or rub against the inner side wall of the first bin section 11, and the transmission chain 23 and the first bin section 11 are usually made of iron, sparks are easily generated during collision or friction, and the material used to produce the shaving board is dry, which may easily cause a fire. Therefore, wear-resistant plastic plates are arranged at positions where collision or friction with the transmission chain 23 is likely to occur, which can effectively prevent the transmission chain 23 from catching fire due to collision or friction during production, thereby ensuring the safety of production. In addition, the arrangement of the first baffle 55 and the second baffle 56 can also prevent the material from directly falling into the transmission chain 23, so that the transmission chain 23 will not be jammed and cannot be normally driven.

[0080] As a specific embodiment of the present application, the height difference between the top of the first belt conveying assembly 41 and the top of the second belt conveying assembly 42 is 30-40 cm, so that the material will not cause too much impact on the second belt conveying assembly 42 during falling, and also help the material to be better loose during falling.

[0081] In the preferred embodiment of the present application, the top of the bin body 1 is provided with an explosion-proof window 17, a dust suction port 18 and a fire-fighting water interface 19, and the sidewall of the bin body 1 is provided with an observation window 10; wherein the explosion-proof window 17 is used to resist the occasional explosion in the bin body 1, so as to prevent the continuation of the explosion shock wave; the dust suction port 18 is used to connect a dust suction device (not shown) to use the dust suction device to suck away the dust generated in the bin body 1; the fire-fighting water interface 19 is used to connect the fire-fighting water, so as to facilitate the delivery of fire-fighting water into the bin body 1 through the fire-fighting water interface 19 to achieve fire extinguishing when on fire; and the observation window 10 is used to facilitate the staff to view the internal condition of the bin body 1.
