Description

Technical Field

[0001] The invention belongs to the technical field of rice husk storage, and in particular relates to a rice husk silo discharging system. Background Art

[0002] At present, silos all adopt the structure of top-in and bottom-out. The top center has a hole and is equipped with a feed barrel that can be extended and retracted with the material level. The bottom of the silo is either flat or conical with a discharge port in the center. The material falls freely from the discharge port to the belt conveyor and is transported to the target position. In order to avoid the situation where the material accumulates in the middle of the silo during feeding and the edge material cannot slide smoothly during discharging, a rotatable hanger is usually set on the top of the silo. The hanger is used to suspend the horizontal screw rod in the silo with a winch. The rotation of the hanger and the lifting of the winch drive the horizontal screw rod to do lifting and sweeping movements in the silo, so that the horizontal screw rod can be used to transport the center material to the edge during feeding and the edge material to the center during discharging, so as to achieve the synchronous lifting and lowering of the edge material level and the center material level during the silo feeding and discharging process.

[0003] The above-mentioned silo structure is usually suitable for the storage of particles and powder materials with a larger specific gravity, such as coal, charcoal, wheat, and corn. However, for rice husk materials required for the brewing process, due to their small specific gravity, the use of this silo will be greatly limited in the feeding and discharging speed. Moreover, since rice husks are light in weight, the structural strength requirements of the silo are relatively low from the perspective of rice husk storage alone. If the above-mentioned silo structure is used, it will inevitably cause a waste of construction costs. However, considering that a revolving hanger structure needs to be arranged on the top of the silo, not only is the structure complex and large, but it will also cause a large additional load on the silo structure. As a result, the structural strength of the silo has to be strengthened, which creates a cost burden for rice husk storage. Summary of the invention

[0020] Please also read Figures 1 to 10 The rice husk silo discharging system provided by the present invention is now described. The rice husk silo discharging system comprises a silo body 10, a tower chamber 20, a lifting turntable 30, and an open vertical auger 40 and a horizontal auger 50; the silo body 10 has a storage chamber 101 and a transfer chamber 102 located below the storage chamber 101, a feed inlet 103 is provided at the center of the top wall of the storage chamber 101, and a discharge port 104 connected to the transfer chamber 102 is provided at the center of the bottom wall; the tower chamber 20 is hoisted and fixed to the inner top wall of the storage chamber 101, and Located directly below the feed port 103, the top surface of the tower chamber 20 forms a conical material guiding surface; the top end of the vertical auger 40 is fixedly connected to the tower chamber 20, and the bottom end passes through the discharge port 104 and is fixedly connected to the discharge port 104; the lifting turntable 30 is connected to the vertical auger 40 by sliding up and down and forms a rotational fit with the vertical auger 40; one end of the horizontal auger 50 is connected to the lifting turntable 30, and the other end extends along the radial direction of the storage chamber 101, which is used to transport rice husks to the vertical auger 40.

[0021] It should be noted that in the present embodiment, a lifting turntable 30 is used to drive the horizontal auger 50 to rise and fall along the vertical auger 40. The vertical auger 40 is used to transport rice husks downward while also acting as a load. Here, the bottom wall of the storage chamber 101 is used to support the vertical auger 40, and the tower chamber 20 connected to the top of the storage chamber 101 is connected to the top of the vertical auger 40 mainly to maintain the vertical state of the vertical auger 40 without bearing the vertical load. Therefore, for the silo body 10, it is only necessary to ensure the vertical bearing performance of the transfer chamber 102, and the storage chamber 101 can be designed to be lightweight, thereby saving the construction cost of the silo body 10; in addition, the transfer chamber 102 can be provided with a door opening for the transfer vehicle to pass through. When discharging, the transfer vehicle can directly enter the transfer chamber 102 and stop under the discharge port 104 to automatically load the rice husks, thereby improving the convenience of rice husk discharge and transportation.

[0022] In the present embodiment, the tower chamber 20 serves as a connection base for the top of the vertical auger 40. Considering that the lower end of the vertical auger 40 is not suitable for arranging power components, the power components of the vertical auger 40 can be arranged in the tower chamber 20. On the other hand, the conical material guide surface at the top of the tower chamber 20 can guide the rice husks falling from the feed port 103 to disperse around, so that the rice husks are evenly scattered on the material level surface in the storage chamber 101, thereby achieving smooth and efficient feeding.

[0023] In the present embodiment, both the vertical auger 40 and the horizontal auger 50 are open structures, that is, the conveying shafts of both can directly contact the rice husks in the storage chamber 101. Specifically, the horizontal auger 50 is located on the material level surface in the storage chamber 101 to convey the rice husks from the periphery to the center, while the part of the vertical auger 40 extending below the material level can efficiently convey the rice husks gathered in the center to the discharge port 104; it should be understood that when the vertical auger 40 conveys the rice husks downward, its open structure is not only capable of fully contacting the surrounding rice husks, but also capable of utilizing the mutual adhesion characteristics of the rice husks to achieve the synchronous falling of the rice husks within a certain rotating area around the vertical auger 40, rather than just the rice husks in direct contact with the vertical auger 40. Of course, the diameter of the discharge port 104 is also larger than the cross-sectional size of the vertical auger 40, thereby greatly improving the discharge efficiency.

[0024] Compared with the prior art, the rice husk silo discharging system provided in the present embodiment can guide the rice husks dropped from the feed port 103 to evenly fall to the surrounding areas by utilizing the conical material guide surface at the top of the tower chamber 20, thereby improving the feeding efficiency while ensuring the flatness of the material level surface in the storage chamber 101; utilizing the horizontal auger 50 to perform a rotary and sweeping motion along the material level surface along with the lifting turntable 30, the rice husks at the edge of the storage chamber 101 can be transported to the vertical auger 40, and the vertical auger 40 can be used to force feed the material to the discharge port 104, thereby preventing the rice husks from being blocked due to agglomeration and bridging problems, thereby improving the rice husk discharging efficiency; the lifting turntable 30 is installed on the vertical auger 40. The bottom end of the vertical auger 40 is fixedly supported on the discharge port 104, thereby reducing the load exerted by the tower chamber 20 connected to the top of the vertical auger 40 on the top wall of the storage chamber 101, thereby reducing the dependence on the structural strength of the storage chamber 101, which is beneficial to reducing the construction cost of the silo body 10; on this basis, a transfer chamber 102 is arranged below the storage chamber 101, and when the rice husks are discharged, the transfer vehicle can directly enter the transfer chamber 102 and stop below the discharge port 104, thereby realizing direct discharge of the rice husks onto the vehicle without the need to set up a separate conveyor, which can not only further save costs but also improve the transfer efficiency of the rice husks after discharge.

[0025] In some embodiments, see Figures 2 to 7The vertical auger 40 includes an auger skeleton 41, a vertical spiral shaft 42, and a first rotary drive member 43; one end of the auger skeleton 41 is fixedly connected to the center of the bottom wall of the tower chamber 20, and the other end is vertically downwardly penetrated and fixed to the discharge port 104; the rotary drive member is fixedly connected to the tower chamber 20; the vertical spiral shaft 42 is penetrated inside the auger skeleton 41, and one end penetrates into the tower chamber 20 and is connected to the output end of the first rotary drive member 43, and the other end extends to the lower end of the auger skeleton 41; the lifting turntable 30 is connected to the auger skeleton 41.

[0026] On the one hand, the auger skeleton 41 can provide a number of connection points at upper and lower intervals for the vertical screw shaft 42, thereby improving the operating stability of the vertical screw shaft 42. On the other hand, the auger skeleton 41 is used as the installation basis of the lifting turntable 30, so that the lifting turntable 30 drives the horizontal auger 50 to rise and fall synchronously along the material level surface. Compared with the existing structure of setting a rotary hanger on the top of the storage chamber 101, not only can the main force point of the barrel body be transferred from the top of the silo body 10 to the bottom, but also the structure of directly connecting the horizontal auger 50 and the lifting turntable 30 can improve the stability of the horizontal auger 50 compared with the method of suspending the horizontal auger 50.

[0027] The first rotating driving member 43 may specifically be a motor, which is arranged in the tower chamber 20 to avoid contact with the rice husks, thereby avoiding the potential safety hazard of ignition of the rice husks due to high temperature or electric sparks during the operation of the first rotating driving member 43 .

[0028] Specifically, the structure of the auger skeleton 41 in this embodiment is as follows: Figure 7 As shown, it includes four vertical poles 411 distributed in a square array and a plurality of connecting rings 412; each connecting ring 412 is distributed at intervals up and down and connected between the four vertical poles 411 to connect the four vertical poles 411 into one. Based on this structure, the vertical spiral shaft 42 is located at the center of the four vertical poles 411 and passes through each connecting ring 412. The four vertical poles 411 are all distributed with limited wear strips 413 at intervals up and down, and the positions of the limited wear strips 413 on each column correspond. The four limited wear strips 413 at the same height of the four vertical poles 411 are all in sliding contact with the edges of the spiral blades of the vertical spiral shaft 42, thereby forming a plurality of radial limited constraints on the vertical spiral shaft 42, thereby preventing the vertical spiral shaft 42 from bending and twisting due to excessive length.

[0029] As a specific implementation of the lifting turntable 30, please refer to Figure 2 , Figure 3 , Figures 6 to 8The lifting turntable 30 includes a stand 31, a lifting drive assembly 32 and a rotating drive assembly 33; the stand 31 is slidably connected to the auger frame 41 and forms a rotational match with the auger frame 41; the lifting drive assembly 32 is arranged on the stand 31 and the output end is connected to the auger frame 41, which is used to drive the stand 31 to lift; the rotating drive assembly 33 is arranged on the stand 31 and is used to drive the stand 31 to rotate; the horizontal auger 50 is fixedly connected to the stand 31. The stand 31 can slide up and down relative to the auger frame 41, and can also rotate, so that the horizontal auger 50 can be driven by the stand 31 to form a coupled movement of lifting and rotating and sweeping, so that the material level can be lowered as a whole.

[0030] For some possible implementations, see Figures 4 to 7 The auger skeleton 41 is symmetrically provided with two racks 44 along the axial direction of the vertical screw shaft 42; the lifting drive assembly 32 includes two second rotating drive members 321 fixedly connected to the platform 31, and the output ends of the two second rotating drive members 321 are provided with driving gears 322, and the two driving gears 322 are respectively meshed and connected with the two racks 44; the platform 31 is also rotatably connected with two first rollers 311 and two second rollers 312; wherein the two first rollers 311 are respectively rolled on the back tooth surfaces of the two racks 44, and the two second rollers 312 are respectively rolled on the wall surfaces of the two racks 44 which are away from each other.

[0031] The second rotating driving member 321 can specifically be an explosion-proof motor. The driving gear 322 at the output end of the second rotating driving member 321 is used to roll the rack 44, so as to realize the lifting and lowering of the platform 31. At the same time, the first roller 311 rolled on the back tooth surface of the rack 44 can cooperate with the driving gear 322 to clamp the rack 44, and the two second rollers 312 can respectively roll the wall surfaces of the two racks 44 that are away from each other. In this way, the two racks 44 can cooperate with the driving gear 322 to serve as the transmission components for the lifting and lowering of the platform 31, and can also cooperate with the rolling of the driving gear 322, the first roller 311, and the second roller 312 on their three surfaces to form a guiding component for the lifting and lowering of the platform 31, thereby improving the compactness of the connection structure of the platform 31 on the auger frame 41 and the lifting and lowering movement stability.

[0032] It should be noted that, in this embodiment, Figure 6As shown, two groups of cleaning members 34 are provided on the stand 31, and the two groups of cleaning members 34 are respectively used to clean the tooth surfaces of the two racks 44. Considering that rice husks are light in weight, they may fall on the tooth surfaces of the racks 44 during the feeding process, and may also adhere to the tooth surfaces of the racks 44 due to the disturbance of the vertical auger 40 and the horizontal auger 50 during the discharging process. If the driving gear 322 rolls the racks 44 with rice husks attached for a long time, on the one hand, it affects the smoothness of lifting and lowering, and on the other hand, due to the friction between the driving gear 322 and the rack 44, the rice husks attached will generate high temperature, which may lead to the safety hazard of ignition. Therefore, cleaning members 34 are provided to sweep away the rice husks attached to the tooth surfaces of the racks 44, thereby improving the smoothness of the lifting and lowering movement of the stand 31 and eliminating safety hazards.

[0033] Specifically, the cleaning member 34 includes a cleaning motor 341 fixed on the stand 31 and a cleaning wheel 342 connected to the output end of the cleaning motor 341, and the cleaning wheel 342 contacts the tooth surface of the rack 44. The cleaning motor 341 drives the cleaning wheel 342 to rotate and sweep away the rice husks attached to the tooth surface, thereby improving the smoothness and safety of the lifting movement of the stand 31.

[0034] For some examples, see Figure 3 and Figure 6 The upper and lower ends of the above-mentioned platform 31 are both provided with slewing support bearings 313, and the upper and lower ends of the platform 31 are respectively fixedly connected to the inner rings of the two slewing support bearings 313, and the outer rings of the two slewing support bearings 313 are commonly connected to a suspension 314, one of the slewing support bearings 313 is provided with a slewing driving member 315 for driving its outer ring to rotate relative to the inner ring, and the horizontal auger 50 is arranged on the suspension 314.

[0035] The inner rings of the upper and lower slewing support bearings 313 are connected to the stand 31, and then the outer rings of the two slewing support bearings 313 are connected to the suspension 314. When the slewing drive 315 drives the outer ring of one of the slewing support bearings 313 to rotate relative to the inner ring, the outer ring of the other slewing support bearing 313 can be synchronously rotated by utilizing the connection of the suspension 314, thereby realizing the slewing motion of the suspension 314. Considering that the horizontal auger 50 is arranged on the suspension 314, the two slewing support bearings 313 distributed at intervals above and below can provide the suspension 314 with two upper and lower connection points, thereby ensuring the connection stability of the suspension 314, and further improving the connection stability of the horizontal auger 50.

[0036] The above-mentioned rotary driving component 315 can specifically be an explosion-proof motor. The rotary driving component 315 can be set on the inner ring of the lower rotary support bearing 313 or directly on the stand 31. A gear is sleeved on its output end, and the outer ring of the lower rotary support bearing 313 is coaxially connected to the gear ring that meshes with the gear. Therefore, when the rotary driving component 315 outputs torque, the gear ring can be driven by the gear to drive the outer ring of the rotary support bearing 313 to rotate relative to the inner ring, thereby realizing the suspension 314 driving the horizontal auger 50 to rotate and sweep.

[0037] Specifically, Figure 2 As shown, the suspension 314 includes a crossbeam 3141 connected to the outer ring of the slewing bearing 313 below, and a diagonal tie rod 3142 connected to the outer ring of the slewing bearing 313 above, and the horizontal auger 50 is connected to the lower part of the crossbeam 3141. The diagonal tie rod 3142 and the crossbeam 3141 form a triangular connection structure, thereby improving the connection stability and load capacity of the suspension 314.

[0038] Specifically, the optional structure of the horizontal auger 50 in this embodiment is as follows: Figure 8 As shown, the transverse auger 50 includes a transverse conveying shaft 51 and a third rotating drive member 52; wherein, the transverse conveying shaft 51 is rotatably connected to the bottom of the suspension 314, and one end of the transverse conveying shaft 51 extends to the side of the vertical auger 40, and the other end extends to the peripheral wall of the storage chamber 101; the third rotating drive member 52 is fixed to the suspension 314 and the output end is connected to the transverse conveying shaft 51.

[0039] To ensure safe operation, the third rotary drive member 52 can be specifically an explosion-proof motor, which drives the transverse conveying shaft 51 to rotate through the third rotary drive member 52, so as to convey the rice husks near the inner wall of the storage chamber 101 to the side of the vertical auger 40. It should be noted that the transverse conveying shaft 51 and the vertical auger 40 form a cross-shaped position, which can facilitate the cross-mounting and fixing of the suspension 314 on the side of the auger frame 41, so that the third rotary drive member 52 and the transverse conveying shaft 51 can be respectively located on both sides of the vertical auger 40, so as to use the weight of the third rotary drive member 52 to balance the rice husks to the storage chamber 101. 01, thereby avoiding a large deflection of the load transmitted from the transverse auger 50 to the auger skeleton 41, which is beneficial to reducing the bending moment load and radial force on the auger skeleton 41, thereby avoiding bending and torsional deformation of the vertical auger 40, and at the same time can also reduce the radial load transmitted to the tower chamber 20 by the auger skeleton 41, thereby reducing the dependence on the structural strength of the silo body 10; on the other hand, the intersection of the transverse conveying shaft 51 and the vertical auger 40 can enable the transverse conveying shaft 51 to convey the rice husk to a position closer to the vertical auger 40, thereby avoiding the rice husk being unable to get close to the vertical auger 40 and affecting the smoothness of the discharge.

[0040] For example, see Fig. 9 The above-mentioned transverse conveying shaft 51 includes a spiral blade segment 511 and a lifting blade segment 512 that are connected to each other; wherein the lifting blade segment 512 is located on the side of the vertical auger 40, and is used to lift rice husks into the vertical auger 40; the spiral blade segment 511 is used to transport rice husks from the periphery of the vertical auger 40 to the lifting blade segment 512.

[0041] The spiral blade segment 511 is a continuous blade, which can push the rice husks from the edge of the storage chamber 101 to the area on the side of the vertical auger 40, and then use the lifting blade segment 512 to lift the rice husks transported by the spiral blade segment 511 on the side of the vertical auger 40 into the interior of the vertical auger 40, thereby avoiding the rice husks from being piled up and accumulated on the side of the vertical auger 40 due to the inability to directly contact the vertical auger 40, thereby ensuring smooth and efficient discharge.

[0042] Please note that Fig. 9 The blade edge of the spiral blade segment 511 is provided with crushing teeth 5111; the lifting blade segment 512 is relatively provided with two groups of lifting pieces 5121, and the two groups of lifting pieces 5121 each include a plurality of blades distributed at spiral intervals, and the spiral directions of the two groups of lifting pieces 5121 are opposite, which are used to cooperate in lifting the rice husks into the vertical auger 40.

[0043] Since rice husks are relatively smooth, in order to prevent the spiral blade segment 511 from slipping and affecting the conveying stability when it contacts with the spiral blade segment 511, a material-breaking tooth 5111 is provided on the blade edge of the spiral blade segment 511. On the one hand, it can avoid the problem of slipping affecting the conveying efficiency, and on the other hand, it can also break up the agglomerated rice husks, thereby further improving the smoothness of material discharge. A group of lifting pieces 5121 close to the spiral blade segment 511 has a spiral direction consistent with the spiral blade segment 511, and another group of lifting pieces 5121 are arranged at intervals in a spiral direction, thereby the two groups of lifting pieces 5121 can cooperate with each other to enable the rice husks to be lifted into the vertical auger 40 in the area between the two groups. Therefore, the area between the two groups of lifting pieces 5121 is aligned with the radial direction of the vertical auger 40, so that the rice husks conveyed by the spiral blade segment 511 can be accurately lifted into the vertical auger 40, thereby avoiding the accumulation of rice husks on the side of the vertical auger 40, thereby improving the smoothness and efficiency of material discharge.

[0044] It should be understood that in this embodiment, please refer to Figure 1The silo body 10 includes a masonry base 11 and a straight silo body 12 connected to the top of the masonry base 11; wherein the interior of the masonry base 11 is hollow to form a transfer chamber 102, and the center of the top surface of the masonry base 11 is recessed downward to form an inverted cone-shaped inner bottom surface of the storage chamber 101; the top surface of the straight silo body 12 is a pointed cone, and the inner top surface of the straight silo body 12 is provided with a plurality of reinforcing beams 121 at intervals along its circumference, and the tower chamber 20 is provided with a plurality of triangular hangers 21 at intervals along its circumference, and each triangular hanger 21 is fixedly connected to one of the reinforcing beams 121.

[0045] The masonry base 11 can be constructed of reinforced concrete or brick-concrete structure to withstand a higher load capacity. At the same time, the inverted cone-shaped top surface can not only facilitate the bottom discharge of the storage chamber 101, but also improve the vertical bearing capacity. On this basis, the straight cylindrical silo body 12 can directly adopt a formed steel cylinder structure or a structure with a lightweight fireproof board sandwiched between two layers of thin steel plates, which can not only reduce costs but also reduce the load on the masonry base 11. In addition, setting the top of the straight cylindrical silo body 12 to a pointed cone shape can improve the vertical load capacity of the silo roof, and cooperate with the reinforcing beam 121 to fix it to the triangular hanger 21 on the periphery of the tower chamber 20, thereby ensuring that the top of the straight cylindrical silo body 12 is evenly stressed, and improving the fixing stability of the tower chamber 20, thereby ensuring the stability of the vertical auger 40.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
