Description

Technical Field

[0001] The utility model relates to the technical field of screw conveyors, in particular to a cantilever screw conveyor. Background Art

[0002] There is a feed port on the top of the cantilever screw conveyor shell, and the bottom or one side of the screw shaft is the discharge port. After the material from the upstream equipment enters the cantilever screw conveyor, it can be directly discharged to the downstream equipment. It is often used in equipment such as waste incineration, boiler slag incineration and catalyst incinerators.

[0003] The cantilever screw conveyor with application number 202320920289.3 comprises a screw conveyor body, a driving motor and a port are respectively installed on both sides of the screw conveyor body, a cleaning door is installed on the side of the port away from the screw conveyor body, a fixing mechanism is arranged on the outside of the cleaning door, and a second annular groove is arranged inside the cleaning door. The utility model rotates the knob, and under the action of the threaded connection, the support block is continuously moved away from the connecting rod, the fixation of the connection between the card block and the first annular groove is cancelled, and the card block and the first annular groove are separated by the mutual attraction of the first magnet and the second magnet, and then the steering wheel is rotated to separate the internal thread from the external thread, and the cleaning door is separated, so that the materials adhering to the spiral blades and the spiral shaft can be cleaned quickly and effectively, the cleaning time of manual labor is reduced, the risk of blockage of the screw conveyor is reduced, and the work efficiency is improved.

[0004] This technical solution makes it easy to open the conveyor to clean the internal auger, but the auger is still inside the machine casing, and it is difficult for workers to go deep into the casing to clean the inner area of ​​the auger. They can only clean the outer surface, which is inconvenient to operate. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a cantilever screw conveyor to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cantilever screw conveyor, comprising an outer shell and a feed pipe, one side of the outer shell is connected to an extension bin, and an inner shaft is arranged inside the extension bin and the outer shell, a sleeve is sleeved on the outside of the inner shaft, and a sealing plate is connected to the other side of the outer shell, hydraulic cylinders are installed on both sides of the top of the feed pipe, and support blocks are connected to the output ends of the hydraulic cylinders.

[0007] By adopting the above technical scheme, the sealing plate is removed to facilitate the extraction of the sleeve and the first auger blade and the second auger blade outside the sleeve from the outer shell. At the same time, the length of the sleeve and the inner shaft can be appropriately extended by extending the length of the bin to prevent the sleeve from falling off directly when the first auger blade is extracted from the outer shell. After that, the output end of the hydraulic cylinder drives the support block to move upward to support the sleeve and the inner shaft to prevent the sleeve and the inner shaft from bending downward due to the influence of gravity due to the large span and no support point for a long time. At the same time, due to the plum blossom-shaped grooves at one end of the inner shaft and the sleeve, the inner shaft can still drive the sleeve to rotate after the sleeve is extracted, thereby facilitating its cleaning.

[0008] Furthermore, the cross section of the inner shaft is plum blossom-shaped, and a plum blossom-shaped groove is provided at one end of the sleeve.

[0009] By adopting the above technical solution, due to the shape of the inner shaft and the plum blossom-shaped groove at one end of the sleeve, the inner shaft can drive the sleeve to rotate, thereby rotating the first auger blade and the second auger blade.

[0010] Furthermore, the sleeve is slidably connected to the inner shaft.

[0011] By adopting the above technical solution, the sleeve and the first auger blade and the second auger blade outside the sleeve can be easily drawn out from the outer shell by removing the sealing plate, and the sleeve is guided by the inner shaft.

[0012] Furthermore, the support block is slidably connected to the shell, and the support block abuts against the sleeve.

[0013] By adopting the above technical solution, after the pressure cylinder is started, the output end drives the support block to move upward to support the sleeve and the inner shaft, thereby avoiding the sleeve and the inner shaft from bending downward due to gravity due to the lack of support points for a long time due to the large span.

[0014] Furthermore, two hydraulic cylinders and two supporting blocks are provided, and the two hydraulic cylinders and the two supporting blocks are symmetrically distributed.

[0015] By adopting the above technical solution, the number of hydraulic cylinders and support blocks is increased, thereby increasing the supporting points for the sleeve and the inner shaft and improving the supporting effect.

[0016] Furthermore, a reducer is installed on one side of the extension bin, and a motor is installed on the input end of the reducer, a feed pipe is connected to the top side of the outer shell, and a discharge pipe is connected to the bottom side of the outer shell, and the first auger blade and the second auger blade are respectively connected to the outside of the sleeve.

[0017] By adopting the above technical solution, after the motor is started, the output end drives the inner shaft to rotate through the reducer. Due to the shape of the inner shaft and the plum blossom-shaped groove at one end of the sleeve, the inner shaft can drive the sleeve to rotate, thereby rotating the first auger blade and the second auger blade. When the upstream equipment is processed, the material passes through the feed pipe into the outer shell. At this time, the material is pushed to the feed pipe through the rotation of the first auger blade. After that, the material passes through the feed pipe under the influence of gravity and enters the downstream equipment. At the same time, the second auger blade will push the material passing above the feed pipe back to the position above the feed pipe to avoid blockage.

[0018] Furthermore, the inner shaft is connected to the output end of the reducer.

[0019] By adopting the above technical solution, after the motor is started, the output end drives the inner shaft to rotate through the reducer, and the inner shaft drives the sleeve to rotate, thereby rotating the first auger blade and the second auger blade.

[0020] Furthermore, the first auger blade is opposite to the second auger blade.

[0021] By adopting the above technical solution, the second auger blade will push the material passing over the top of the discharge pipe back to the top of the discharge pipe to avoid material blockage.

[0022] Furthermore, a clamping block is fixed to one end of the sleeve, and the clamping block passes through one side of the sealing plate.

[0023] By adopting the above technical solution, the staff pulls the sealing plate and the support frame to make the sealing plate translate away from the shell, and at the same time, through the setting of the clamping block, the sealing plate translates to pull the sleeve out of the shell.

[0024] Furthermore, the cross section of the block is in an "H" shape.

[0025] By adopting the above technical solution, the H shape can be embedded in the interior of the sealing plate, and the sleeve is fixed to the clamping block, so that when the sealing plate moves horizontally, the clamping block is driven to move horizontally and then the sleeve is pulled out.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] The utility model provides an extension bin, a sealing plate, a hydraulic cylinder, a support block, a sleeve and an inner shaft. By removing the sealing plate, the sleeve and the first auger blade and the second auger blade outside the sleeve can be easily pulled out from the outer shell. At the same time, the length of the sleeve and the inner shaft can be appropriately extended by the length of the extension bin to prevent the sleeve from directly falling off when the first auger blade is pulled out from the outer shell. After that, the output end of the hydraulic cylinder drives the support block to move upward to support the sleeve and the inner shaft, so as to prevent the sleeve and the inner shaft from bending downward due to the influence of gravity due to the large span and no support point for a long time. At the same time, due to the plum blossom-shaped grooves at one end of the inner shaft and the sleeve, the inner shaft can still drive the sleeve to rotate after the sleeve is pulled out, thereby facilitating its cleaning. The structure can be pulled out without entering the inside of the machine, and cleaning is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1:

[0035] Cantilever screw conveyor, such as Figure 1-Figure 4As shown, it includes a shell 1 and a feed pipe 6. An extension bin 2 is connected to one side of the shell 1. The length of the extension bin 2 can appropriately extend the length of the sleeve 11 and the inner shaft 14 to prevent the sleeve 11 from falling off directly when the first auger blade 12 is pulled out of the shell 1; an inner shaft 14 is arranged inside the extension bin 2 and the shell 1. The cross section of the inner shaft 14 is plum blossom-shaped. The sleeve 11 is sleeved on the outside of the inner shaft 14. A plum blossom-shaped groove is provided at one end of the sleeve 11. Due to the shape of the inner shaft 14 and the plum blossom-shaped groove at one end of the sleeve 11, the inner shaft 14 can drive the sleeve 11 to rotate; the sleeve 11 is slidably connected to the inner shaft 14, and the sleeve 11 is Pull it out from the outer shell 1; a sealing plate 7 is connected to the other side of the outer shell 1, which plays a role of sealing when feeding; hydraulic cylinders 8 are installed on both sides of the top of the feeding pipe 6, and the output end of the hydraulic cylinder 8 is connected to a support block 10. There are two hydraulic cylinders 8 and support blocks 10, and the two hydraulic cylinders 8 and support blocks 10 are symmetrically distributed. The support block 10 is slidably connected to the outer shell 1, and the support block 10 abuts against the sleeve 11. After the hydraulic cylinder 8 is started, the output end drives the support block 10 to move upward to support the sleeve 11 and the inner shaft 14, so as to avoid the sleeve 11 and the inner shaft 14 bending and deforming downward due to the influence of gravity due to the long span being too large and having no support point.

[0036] See also Figure 1-Figure 4 In the above embodiment, a reducer 3 is installed on one side of the extension bin 2, and a motor 4 is installed on the input end of the reducer 3. The inner shaft 14 is connected to the output end of the reducer 3, and the first auger blade 12 and the second auger blade 13 are respectively connected to the outside of the sleeve 11. After the motor 4 is started, the output end drives the inner shaft 14 to rotate through the reducer 3, and the inner shaft 14 drives the sleeve 11 to rotate so that the first auger blade 12 and the second auger blade 13 rotate; the first auger blade 12 is opposite to the second auger blade 13, and the second auger blade 13 will push the material passing through the top of the discharge pipe 6 back to the position above the discharge pipe 6 to avoid blockage; a feed pipe 5 is connected to one side of the top of the outer shell 1, and the discharge pipe 6 is connected to one side of the bottom of the outer shell 1. When the upstream equipment is processed, the material passes through the feed pipe 5 into the outer shell 1. At this time, the material is pushed to the discharge pipe 6 by the rotation of the first auger blade 12, and then the material passes through the discharge pipe 6 under the influence of gravity and enters the downstream equipment. Embodiment 2:

[0037] On the basis of the above-mentioned embodiment 1, although the structure can be pulled out without entering the inside of the machine by setting the extension bin 2, the sealing plate 7, the hydraulic cylinder 8, the support block 10, the sleeve 11 and the inner shaft 14, and the cleaning is convenient and quick; but the sleeve 11 is cylindrical and has no force application point, which makes it difficult to pull out; now by setting the clamping block 9, the sleeve 11 can be easily pulled out.

[0038] See also Figure 1-Figure 3In the above embodiment, a clamping block 9 is fixed at one end of the sleeve 11, and the clamping block 9 passes through one side of the sealing plate 7. The cross-section of the clamping block 9 is in an "H" shape. The staff pulls the sealing plate 7 and the support frame to make the sealing plate 7 move horizontally away from the outer shell 1. At the same time, the setting of the clamping block 9 makes the sealing plate 7 move horizontally to pull the sleeve 11 out of the outer shell 1.

[0039] The implementation principle of the utility model is as follows: first, the staff connects the feed pipe 5 with the upstream equipment, and then the staff connects the discharge pipe 6 with the downstream equipment. After the conveyor is installed, the staff turns on the motor 4. After the motor 4 is started, the output end drives the inner shaft 14 to rotate through the reducer 3. Due to the shape of the inner shaft 14 and the plum blossom-shaped groove at one end of the sleeve 11, the inner shaft 14 can drive the sleeve 11 to rotate, thereby rotating the first auger blade 12 and the second auger blade 13. When the upstream equipment is processed, the material passes through the feed pipe 5 into the housing 1. At this time, the material is pushed to the discharge pipe 6 by the rotation of the first auger blade 12. Then, the material passes through the discharge pipe 6 under the influence of gravity and enters the downstream equipment. At the same time, the second auger blade 13 will push the material passing above the discharge pipe 6 back to the position above the discharge pipe 6 to avoid blockage.

[0040] When cleaning is required, the staff first turns off the motor 4, and then moves a support frame with rollers to the bottom of the sealing plate 7, and then removes the sealing plate 7 from the housing 1 by unscrewing the bolts. At this time, the sealing plate 7 is supported by the support frame prepared in advance by the staff;

[0041] The staff pulls the sealing plate 7 and the support frame to make the sealing plate 7 move horizontally away from the outer shell 1. At the same time, the sealing plate 7 can be moved horizontally through the setting of the clamping block 9 to pull the sleeve 11 out of the outer shell 1, so that the first auger blade 12 and the second auger blade 13 can be pulled out of the outer shell 1. At the same time, the length of the sleeve 11 and the inner shaft 14 can be appropriately extended by extending the length of the bin 2 to prevent the sleeve 11 from falling off directly when the first auger blade 12 is pulled out of the outer shell 1. Then the staff turns on the hydraulic cylinder 8. After the hydraulic cylinder 8 is started, the output end drives the support block 10 to move upward to support the sleeve 11 and the inner shaft 14 to prevent the sleeve 11 and the inner shaft 14 from bending downward due to the influence of gravity due to the large span and no support point for a long time. At the same time, after the sleeve 11 is pulled out, the inner shaft 14 can still drive the sleeve 11 to rotate, so that the staff can clean it easily. After cleaning, only the reverse operation is required to complete the installation.
