Description

Technical Field

[0001] The invention relates to the technical field of bulk material unloading and discharging, and in particular to a multi-point unloading machine. Background Art

[0002] At present, silos of various diameters, shapes, structures, etc. have been widely used in the field of bulk material transportation and processing. In many related industries such as electricity, metallurgy, mining, chemical industry, grain, cement, environmental protection, and medicine, silos are mostly used to store various bulk materials transported from upstream processes, and unload materials to the next level equipment according to the production process requirements to meet the continuity and stability of the production process.

[0003] Most of the existing silos have a cone-shaped hopper structure at the bottom. When bulk materials flow downward under gravity and are transported outward, in most cases, the flow rate of the materials in the middle part is fast, and the flow rate of the materials in the outer part is slow. After a period of time, a large amount of hanging and accumulation of materials begin to appear on the side wall of the hopper, causing the effective flow outlet cross-sectional area of ​​the hopper to become smaller and smaller, resulting in the bulk material discharge capacity in the silo failing to meet production needs, and even various blockages often occur, which seriously affects the normal operation of the overall production system. In a Chinese patent (application number: CN202210264129.8), a vibrating silo bottom discharger is disclosed. The discharger is provided with a paddle structure on the outside of the activator. During the use of the device, when the material has structural phenomena in the discharge hopper, the arched materials in the discharge hopper are broken up under the action of the swing of the paddle, and then cooperated with the vibration reduction motor to make the arch-breaking effect of the device more obvious and the material passes more smoothly. The device clears the materials by swinging and vibrating the paddle. This method easily leads to large smoke and dust of bulk materials, and poor clearing effect for special bulk materials such as toxic, irritating odor, and high temperature. At the same time, the dispersed raw materials still need to be discharged through the conical hopper, and it is still easy for the material flow rate in the middle part to be fast and the material flow rate in the outer part to be slow.

DETAILED DESCRIPTION

[0032] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] Embodiment 1, as Figure 1-Figure 5 As shown, a multi-point bin discharging machine includes a discharging pipe 2, which is fixedly installed at the outlet of a bin 1, an outer cylinder 4 is welded to the outer side of the discharging pipe 2, and a bottom plate 5 is fixedly installed at the bottom of the outer cylinder 4;

[0034] A material-prying assembly 7 is rotatably mounted on the top of the bottom plate 5, and a plurality of discharge ports 8 are arranged at the bottom of the bottom plate 5. The material-prying assembly 7 is used to push the bulk materials to the discharge ports 8 evenly and orderly. A driving device 6 is fixedly mounted on the bottom of the bottom plate 5, and the driving device 6 is used to drive the material-prying assembly 7 to rotate.

[0035] Furthermore, a plug-in door is provided at the bottom of the discharge port 8, and an electric or pneumatic plug-in door can be provided according to specific working conditions.

[0036] During installation, the discharge pipe 2 can be installed on the bottom of the silo 1 using a flange. The device is easy to install. The driving device 6 drives the material shifting assembly 7 to rotate. The material shifting assembly 7 pushes the bulk material to the discharge port 8 evenly and orderly, and then discharges it evenly through the discharge port 8. It can achieve safe and effective sealing. During the unloading process, there is no dust leakage on site. It can solve the storage and unloading problems of special bulk materials such as toxic, irritating odor, and high temperature. The working environment of the equipment is safe and environmentally friendly.

[0037] Embodiment 2, based on the above embodiment, further includes: an outer side of the discharge pipe 2 is sleeved with an adjusting sleeve 3, an outer side of the adjusting sleeve 3 is fixedly installed with an adjusting screw 31, the adjusting sleeve 3 is located in the outer cylinder 4, and the adjusting screw 31 is threadedly connected to the outer cylinder 4.

[0038] By rotating the adjusting screw 31, the adjusting screw 31 drives the adjusting stop sleeve 3 to rise and fall, thereby changing the distance between the adjusting stop sleeve 3 and the material shifting assembly 7, adjusting the material height in the material shifting assembly 7, and then coordinating with the speed of the adjusting driving device 6, the material discharge amount can be controlled.

[0039] Embodiment 3, based on the above embodiment, provides a set of material shifting components 7 structure;

[0040] like Figure 5 As shown, the material shifting assembly 7 includes a first material shifting ring 71, which is rotatably mounted on the top of the base plate 5, is coaxial with the outer cylinder 4, and is in close contact with the inner wall of the outer cylinder 4, and a plurality of groups of fixed material shifting rods 72 are arranged in a ring shape inside the first material shifting ring 71, and a plurality of groups of material shifting tooth plates 73 are arranged in a ring shape on the inner wall of the first material shifting ring 71, and the output end of the driving device 6 is connected to the first material shifting ring 71.

[0041] The material falls into the first material-shifting ring 71 through the discharge pipe 2 and the adjustment stopper sleeve 3, and the driving device 6 drives the first material-shifting ring 71 to rotate, and the first material-shifting ring 71 drives the fixed material-shifting rod 72 to rotate, and the fixed material-shifting rod 72 gradually moves the bulk material at the center to the periphery of the first material-shifting ring 71, and then the material-shifting tooth plate 73 discharges the bulk material at the periphery to the discharge port 8 evenly and orderly.

[0042] This embodiment is mainly used for materials with relatively low viscosity. The bending angle of the fixed material lever 72 can also be determined according to the particle size of the material, and is suitable for occasions where bulk materials are required.

[0043] Embodiment 4, based on the above embodiment, provides another set of material shifting assembly 7 structure;

[0044] like Figure 6-Figure 11As shown, the material shifting assembly 7 includes a second material shifting ring 74 and a central material shaft 75. The inner wall of the second material shifting ring 74 is also annularly provided with multiple sets of material shifting tooth plates 73. Multiple sets of elastic shifting rods 76 are arranged between the second material shifting ring 74 and the central material shaft 75. A driving wheel 62 and a driven wheel 63 are rotatably installed at the bottom of the bottom plate 5. The driving wheel 62 and the driven wheel 63 are driven by friction. The driven wheel 63 is fixedly connected to the central material shaft 75. The driving wheel 62 is connected to the output end of the driving device 6. A transmission window is opened in the outer cylinder 4. A driving wheel 9 is rotatably installed inside the transmission window. The driving wheel 9 is driven by a motor. The driving wheel 9 and the second material shifting ring 74 are driven by friction.

[0045] The driving wheel 9 and the driving wheel 62 are started at the same time, the driving wheel 9 drives the second material shifting ring 74 to rotate, the driving wheel 62 drives the driven wheel 63 to rotate, and the driven wheel 63 drives the central material shaft 75 to rotate. By controlling the rotation speed of the driving wheel 9 and the driving wheel 62, the second material shifting ring 74 and the central material shaft 75 are rotated synchronously, and the direction of rotation is opposite to the bending direction of the elastic shifting rod 76, ensuring that when the material is shifted, the material will give the elastic shifting rod 76 a bending force in the same direction, ensuring the structural stability of the elastic shifting rod 76;

[0046] Through the arrangement of this embodiment, it is possible to adjust the material particle size without customization, and it is suitable for occasions where bulk materials are not fixed. The central material shaft 75 is controlled to rotate relative to the second material shifting ring 74. When a certain length of elastic shifting rod 76 is wound around the central material shaft 75, the elastic shifting rod 76 is straightened, which is suitable for large-particle materials and the material shifting is more stable. When the central material shaft 75 relaxes the elastic shifting rod 76, the elastic shifting rod 76 is bent at a certain angle under the action of its own elastic force, which is suitable for small-particle materials and can improve the conveying efficiency.

[0047] Generally, there are many material-push rods in a discharger, and their surface area is large. When the viscosity of the material is large, the material is easy to stick to it. However, through the design of the present invention, while discharging, the second material-push ring 74 and the central material shaft 75 are controlled to rotate differentially repeatedly, so that the elastic material-push rod 76 is repeatedly stretched and bent, which can bounce the material on its surface and break up the material with high viscosity. The unloading effect is better, and the material with high viscosity can be discharged for a long time. There is no need for manual cleaning after unloading, and it is more convenient to use.

[0048] Embodiment 5, based on the above embodiment, further includes that the outer sides of the driving wheel 62, the driven wheel 63, the second shifting ring 74 and the driving wheel 9 are all provided with friction grooves, and this design can improve the transmission stability.

[0049] Embodiment 6, on the basis of the above embodiment, further includes: a sliding brake rod 69 is slidably connected to the bottom of the base plate 5, a brake head is provided on the side of the sliding brake rod 69 close to the driven wheel 63, a swing brake rod 10 is hinged on the top of the outer cylinder 4, an arc-shaped brake head 101 is provided on the top of the swing brake rod 10, a brake window is provided on the outer side of the outer cylinder 4, the arc-shaped brake head 101 can swing in the brake window, the arc-shaped brake head 101 can be tangent to the outer surface of the second material shifting ring 74, and the center of the tangent circle coincides with the swinging center of the swing brake rod 10, the contact area between the brake head and the driven wheel 63 is greater than the contact area between the arc-shaped brake head 101 and the second material shifting ring 74, a hinge groove is provided at the end of the sliding brake rod 69 away from the driven wheel 63, a hinge guide groove 610 is provided inside the hinge groove, and a hinge column is provided at the bottom end of the swing brake rod 10, and the hinge column is inserted into the hinge guide groove 610.

[0050] At the same time, the driving wheel 9 and the active wheel 62 are started, the driving wheel 9 drives the second material shifting ring 74 to rotate, the active wheel 62 drives the driven wheel 63 to rotate, and the driven wheel 63 drives the center material shaft 75 to rotate. By controlling the rotation speed of the driving wheel 9 and the active wheel 62, the second material shifting ring 74 and the center material shaft 75 are rotated synchronously, and then the sliding brake rod 69 is controlled to slide in the direction of the driven wheel 63. When the sliding brake rod 69 drives the brake head to press on the driven wheel 63, the driven wheel 63 stops rotating, and the sliding brake rod 69 drives the swinging brake rod 10 to swing, and the swinging brake rod 10 drives the arc-shaped brake head 101 away from the second material shifting ring 74. At this time, the second material shifting ring 74 and the center material shaft 75 rotate differentially, and the center material shaft 75 reels the elastic shifting rod 76. The contact time is short, but the contact area is large, the braking force is large, and the elastic shifting rod 76 has a short contact time. The rod 76 is quickly straightened, and then the sliding brake rod 69 is controlled to move away from the driven wheel 63. The sliding brake rod 69 drives the swinging brake rod 10 to swing, and the swinging brake rod 10 drives the arc-shaped brake head 101 to approach the second material shifting ring 74. Since the arc-shaped brake head 101 can be tangent to the outer surface of the second material shifting ring 74, the contact area is small and the braking force is small. However, since the center of the tangent circle coincides with the swing center of the swinging brake rod 10, there will be contact during the swing back, and the contact time is long. The elastic lever 76 bends slowly. Therefore, by setting it in this way, while ensuring that the rotation speed of the driving wheel 9 and the driving device 6 remains unchanged, the effect of controlling the differential rotation of the second material shifting ring 74 and the center material shaft 75 can be achieved. Moreover, it is quickly straightened and slowly bent, which can better break up the material and shake off the material on the elastic lever 76, and the control effect is better.

[0051] Embodiment 7, on the basis of the above embodiments, further includes: a transmission box 61 is fixedly installed at the bottom of the base plate 5, the driving wheel 62 and the driven wheel 63 are both located in the transmission box 61, and the sliding brake rod 69 is slidably connected in the transmission box 61, an adjusting motor 64 is fixedly installed inside the transmission box 61, a worm 65 is fixedly installed at the output end of the adjusting motor 64, a worm wheel 66 is rotatably installed inside the transmission box 61, the worm wheel 66 is meshed with the worm 65, a crank wheel 67 is fixedly installed on the outer side of the worm wheel 66, a crank rod 68 is hinged on the outer side of the crank wheel 67, and the other end of the crank rod 68 is hinged to the sliding brake rod 69.

[0052] By controlling the power supply of the adjusting motor 64, the adjusting motor 64 drives the worm 65 to rotate, the worm 65 drives the worm wheel 66 to rotate, the worm wheel 66 drives the crank wheel 67 to rotate, the crank wheel 67 drives the crank rod 68 to swing, and the crank rod 68 drives the sliding brake rod 69 to slide back and forth. When the bending angle of the elastic lever 76 needs to be adjusted, it is only necessary to control the rotation angle of the adjusting motor 64. Under the action of the one-way transmission of the worm wheel, the position of the sliding brake rod 69 will not change arbitrarily, and the adjustment is more stable.

[0053] Embodiment 8, based on the above embodiment, further includes that the inner wall of the outer cylinder 4 is provided with a sealing convex ring 41, the sealing convex ring 41 is located directly above the second material shifting ring 74, and the top of the sealing convex ring 41 is designed to be inclined downward. Through this design, the sealing between the second material shifting ring 74 and the outer cylinder 4 can be improved to prevent material from leaking from the brake window and the transmission window.

[0054] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
