Description

TECHNICAL FIELD

[0001] The present application relates to an auger device, in particular to an auger device of a bulk feed transport vehicle. BACKGROUND

[0002] The auger device of the bulk feed transport vehicle generally comprises a vertical lifting auger. In the late stage of unloading, especially in the stage close to emptying the vehicle compartment, as the amount of material in the vehicle compartment continues to decrease, the material entering the lifting auger gradually decreases. When the amount of material in the lifting auger decreases to a certain extent, the situation of column breakage or low filling rate is prone to occur, which causes the original conveying mechanical balance to be broken. At this time, the pushing force of the auger propeller blade cannot effectively counteract the downward force of gravity on the sparse material column, and it is difficult to maintain a stable material conveying state, the remaining material cannot be effectively pushed by the propeller blade, resulting in the remaining material sliding down along the propeller blade to form a backflow. This backflow phenomenon can greatly reduce the actual conveying efficiency of the lifting auger. More seriously, the sliding material and the newly entered material at the bottom end of the lifting auger are extruded and accumulated to form an "arched plug" phenomenon, further aggravating the deterioration of the conveying state.

[0019] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0020] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Reference Figures 1 to 7 The present invention proposes an auger device for a bulk feed transport vehicle. The device includes a directional auger 1, a lifting auger 2 and a steering auger 3 connected in sequence. The lifting auger 2 includes a vertically extending housing 4, a rotating shaft 5 rotatably disposed in the housing 4, a propeller blade 51 integrally disposed on the outer side wall of the rotating shaft 5, and a first rotational power component 52 drivenly connected to the rotating shaft 5. A blade pushing channel 41 is provided between the outer side wall of the rotating shaft 5 and the inner side wall of the housing 4. A pneumatic blowing channel 53 is provided inside the rotating shaft 5. A material guiding channel 42 is connected between the top end of the pneumatic blowing channel 53 and the steering auger 3. A material feeding mechanism 6 is connected to the bottom end of the pneumatic blowing channel 53. The device has a paddle-pushing mode, in which the first rotary power component 52 drives the rotary shaft 5 to rotate. The device has a pneumatic blowing mode. In the pneumatic blowing mode, an airflow moving from bottom to top is generated in the pneumatic blowing channel 53, and the feeding mechanism 6 sends the material in the paddle pushing channel 41 into the pneumatic blowing channel 53.

[0022] In the early stage of unloading, when there is sufficient material in the carriage, the device operates in paddle push mode. In paddle push mode, the first rotary power component 52 drives the rotary shaft 5 to rotate, thereby feeding the material from the bottom of the paddle push channel 41 into the steering auger 3 connected to the top of the paddle push channel 41 via the propeller blades 51. In the later stage of unloading, when there is insufficient material in the carriage, the device switches to pneumatic blowing mode. In pneumatic blowing mode, an airflow moving from bottom to top is generated in the pneumatic blowing channel 53. At the same time, the feeding mechanism 6 feeds the material in the paddle push channel 41 into the pneumatic blowing channel 53, causing the material to be carried upward by the airflow and finally enter the steering auger 3 through the guide channel 42.

[0023] Understandably, this device employs a paddle-driven pushing mode when materials are plentiful and switches to a pneumatic blowing mode when materials are insufficient. This design achieves efficient, high-flow-rate conveying through the mechanical pushing force of the propeller blades 51 during periods of abundant material supply, while simultaneously mitigating the downward pull of gravity on sparse material columns through airflow entrainment during periods of insufficient material supply. This effectively avoids problems such as material slippage, backflow, and blockage. In this way, not only is unloading efficiency guaranteed, but stable conveying of materials throughout the entire cycle from plentiful to depleted is also achieved, significantly improving the operational adaptability and overall efficiency of bulk feed transport vehicles.

[0024] Reference Figures 1 to 3 As can be seen, the core tube 7 is rotatably provided inside the rotating shaft 5, and the pneumatic blowing channel 53 is provided inside the core tube 7.

[0025] Reference Figures 1 to 3 ,as well as Figure 6 and Figure 7 As can be seen, the feeding mechanism 6 includes a rotating seat 61 rotatably sleeved on the outside of the core tube 7, and a second rotating power assembly 62 drivenly connected to the rotating seat 61. The rotating seat 61 is provided with a temporary storage channel 63, and the rotating seat 61 has a first rotating position and a second rotating position. When the rotating seat 61 is in the first rotating position, the temporary storage channel 63 is connected to the blade pushing channel 41, and the temporary storage channel 63 is isolated from the pneumatic blowing channel 53. When the rotating seat 61 is in the second rotating position, the temporary storage channel 63 is isolated from the blade pushing channel 41, and the temporary storage channel 63 is connected to the pneumatic blowing channel 53.

[0026] When material is insufficient, the first rotary power component 52 stops driving the rotary shaft 5, and the second rotary power component 62 begins driving the rotary seat 61 to rotate. When the rotary seat 61 rotates to the first rotation position, the temporary storage channel 63 connects with the paddle pushing channel 41, and the material in the paddle pushing channel 41 falls into the temporary storage channel 63 under the action of gravity. Subsequently, the rotary seat 61 rotates to the second rotation position, and the temporary storage channel 63 connects with the pneumatic blowing channel 53. The material in the temporary storage channel 63 falls into the pneumatic blowing channel 53 under the action of gravity, and is then carried upward by the airflow in the pneumatic blowing channel 53, and finally enters the steering auger 3 through the guide channel 42. The rotary seat 61 cycles between the first rotation position and the second rotation position to achieve continuous pneumatic conveying of materials.

[0027] It should be noted that when the rotating seat 61 rotates to the second rotating position, the temporary storage channel 63 is isolated from the paddle pushing channel 41, which can effectively prevent the airflow in the pneumatic blowing channel 53 from blowing the material in the temporary storage channel 63 back into the paddle pushing channel 41, thus ensuring the stability and reliability of pneumatic conveying.

[0028] Reference Figures 1 to 3 ,as well as Figure 6 and Figure 7 As can be seen, the bottom end of the core tube 7 is provided with a sieve plate 71, a temporary storage chamber 72 is formed above the sieve plate 71, and a first air guide channel 73 is connected below the sieve plate 71. The side wall of the core tube 7 is provided with a feeding channel 74 and a second air guiding channel 75 from bottom to top; When the rotating seat 61 is in the first rotating position, the first air guide channel 73 applies positive pressure to the pneumatic blowing channel 53, and the second air guide channel 75 is closed. When the rotating seat 61 is in the second rotating position, the first air guide channel 73 applies negative pressure to the pneumatic blowing channel 53, and the second air guide channel 75 applies positive pressure to the pneumatic blowing channel 53.

[0029] When the rotating seat 61 is in the second rotation position, the material in the temporary storage channel 63 falls onto the screen plate 71 at the bottom of the core tube 7 under the action of gravity through the feeding channel 74. At this time, based on the fact that the second air guide channel 75 is located above the feeding channel 74, and the first air guide channel 73 applies negative pressure to the pneumatic blowing channel 53 and the second air guide channel 75 applies positive pressure to the pneumatic blowing channel 53, a positive pressure zone is formed in the temporary storage chamber 72 above the screen plate 71, and a negative pressure zone is formed below the screen plate 71, generating an air pressure difference. This air pressure difference drives the gas in the pneumatic blowing channel 53 to flow from the positive pressure zone to the negative pressure zone, thereby using air pressure to compact the material on the screen plate 71, making the material form a tight plug, effectively improving the overall compactness of the plug. Subsequently, when the rotating seat 61 rotates to the second rotation position, the first air guide channel 73 applies positive pressure to the pneumatic blowing channel 53, causing an upward airflow in the channel, which in turn carries the plug above the screen plate 71 upward. Understandably, during the process of applying positive pressure from the first air guide channel 73 to the pneumatic blowing channel 53, the second air guide channel 75 is closed simultaneously. This prevents the material plug from being blown apart by the radial airflow generated by the second air guide channel 75 as it passes from bottom to top, thus preventing the material plug from breaking into discrete particles and avoiding the change of the conveying state from dense phase conveying to dilute phase conveying. This eliminates the problems of a significant increase in energy consumption and a significant decrease in conveying efficiency.

[0030] In addition, during the rotation of the rotating seat 61, the first air guide channel 73 and the second air guide channel 75 alternately apply positive pressure to the pneumatic blowing channel 53, so that the material plug that has moved above the second air guide channel 75 is continuously subjected to positive pressure and keeps moving upward, effectively preventing the material plug from sliding back due to interruption of positive pressure, and further ensuring the stability of conveying.

[0031] It should be noted that improving the tightness of the bolt has the following advantages: Firstly, it can enhance the "pushing efficiency" of the airflow in the subsequent pneumatic blowing channel 53 on the material - the kinetic energy of the airflow can be concentrated on the entire material plug, avoiding the airflow penetration and kinetic energy waste caused by the material being too loose, thereby reducing the backflow loss of the material due to gravity sliding down and significantly increasing the actual conveying capacity. Secondly, the overall suspension resistance of the compacted material clump is more stable, and it can maintain vertical rise without relying on excessively high wind speeds. This not only reduces the energy consumption of the blower, but also avoids flow field disturbances (such as eddies and stratification) caused by high-speed airflow, reduces the risk of sedimentation and blockage in the pneumatic blowing channel 53, and improves the continuity of conveying. Third, the tight material plugs are not easily blown apart by the airflow, which can significantly reduce dust caused by the rising airflow during vertical conveying, reduce material loss and cross-contamination of the environment, and make the friction between the material clump and the pipe wall of the pneumatic conveying channel 53 more uniform when the material clump moves as a whole, avoiding the aggravated wear caused by local high-speed impact and extending the service life of the equipment.

[0032] Reference Figures 1-7The rotating seat 61 is provided with a first air passage 64 corresponding to the first air guide passage 73 and a second air passage 65 corresponding to the second air guide passage 75. A support seat 8 is rotatably fitted on the outer side of the rotating seat 61. The support seat 8 is provided with a first air supply connector 81 and an air intake connector 82 corresponding to the first air passage 64. The support base 8 is also provided with a second air supply connector 83 corresponding to the second air passage 65; When the rotating seat 61 is in the first rotating position, the first air passage 64 is connected to the first air supply connector 81, the first air passage 64 is isolated from the air intake connector 82, and the second air passage 65 is isolated from the second air supply connector 83. When the rotating seat 61 is in the second rotating position, the first air passage 64 is connected to the air intake connector 82, the first air passage 64 is isolated from the first air supply connector 81, and the second air passage 65 is connected to the second air supply connector 83.

[0033] When the rotating seat 61 is in the first rotating position, the first air passage 64 is connected to the first air supply connector 81, so that an airflow moving from bottom to top is generated in the pneumatic blowing channel 53. At this time, the first air passage 64 is isolated from the suction connector 82, preventing the airflow in the pneumatic blowing channel 53 from flowing out through the suction connector 82, thus preventing the generation of an airflow moving from bottom to top in the pneumatic blowing channel 53. The second air passage 65 is isolated from the second air supply connector 83, preventing the material plug from being blown apart by the radial airflow generated by the second air passage 65 when it passes through the second air passage 65 from bottom to top, destroying its dense structure, causing the material plug to break into discrete particles, changing from dense phase conveying to dilute phase conveying, greatly increasing energy consumption and reducing conveying efficiency. In addition, it can also prevent two positive pressure airflows from flowing into the pneumatic blowing channel 53 at the same time, causing flow field turbulence.

[0034] When the rotating seat 61 is in the second rotating position, the first air passage 64 is connected to the suction connector 82, which in turn connects the suction connector 82 to the first air guide passage 73, thereby applying negative pressure to the pneumatic blowing passage 53. The second air passage 65 is connected to the second air supply connector 83, which in turn connects the second air supply connector 83 to the second air guide passage 75, thereby applying positive pressure to the pneumatic blowing passage 53.

[0035] Reference Figure 6 and Figure 7 An annular first air guide groove 76 is provided on the outer wall of the core tube 7, and the first air guide channel 73 is connected to the first air guide groove 76.

[0036] When the core tube 7 is in the second position, the first air guide groove 76 is configured such that the first air passage 64 is connected to the first air guide groove 76 every time the rotating seat 61 rotates 180 degrees, thereby allowing the first air guide passage 73 to connect to the first air supply connector 81 or the air intake connector 82. It should be noted that when the core tube 7 is in the first position, the first air passage 64 is isolated from the first air guide groove 76.

[0037] As a further improvement of the present invention, the core tube 7 is provided with a third air guiding channel 77, an air permeation channel 78 and a material discharge channel 79. The side wall of the rotating shaft 5 is provided with an air jet hole 54 corresponding to the air passage 78 and a guide hole 55 corresponding to the discharge passage 79; The housing 4 is provided with a third air supply connector 43 corresponding to the third air guide channel 77, and the material guide hole 55 is connected to the material guide channel 42; The core tube 7 is connected to the sliding force assembly 9, and the core tube 7 has a first vertical position and a second vertical position; When the core tube 7 is in the first position, the third air guide channel 77 is connected to the third air supply connector 43, the air permeation channel 78 is connected to the jet hole 54, and the discharge channel 79 is isolated from the guide hole 55. When the core tube 7 is in the second position, the third air guide channel 77 is isolated from the third air supply connector 43, the air permeation channel 78 is isolated from the air jet hole 54, and the discharge channel 79 is connected to the guide hole 55.

[0038] When there is sufficient material, the device operates in paddle push mode. To further improve the material conveying efficiency in paddle push mode, the core tube 7 is in the first position, the third air guide channel 77 is connected to the third air supply connector 43, the air permeation channel 78 is connected to the jet nozzle 54, the third air supply connector 43 supplies gas into the pneumatic blowing channel 53, and the airflow in the pneumatic blowing channel 53 is sprayed into the paddle push channel 41 through the jet nozzle 54 to blow the material on the propeller blades 51, which is beneficial to the material conveying.

[0039] As a further improvement of the present invention, an annular second air guide groove 70 is provided on the outer side wall of the core tube 7, and the air passage 78 is connected to the second air guide groove 70.

[0040] When in the blade pushing mode, the first rotating power component 52 drives the rotating shaft 5 to rotate continuously, while the core tube 7 remains stationary. At this time, the jet hole 54 and the ventilation channel 78 will be staggered. In order to ensure that the airflow in the pneumatic blowing channel 53 can be continuously sprayed into the blade pushing channel 41, a second air guide groove 70 is provided, which can keep the ventilation channel 78 and the second air guide groove 70 connected during the rotation of the rotating shaft 5.

[0041] As a further improvement of the present invention, the bottom end of the paddle pushing channel 41 is trumpet-shaped, the top end of the pneumatic blowing channel 53 is provided with a guide cone 56, and the guide channel 42 is slope-shaped.

[0042] The trumpet shape helps the material in the paddle push channel 41 fall into the temporary storage channel 63 under the action of gravity. Similarly, the guide cone 56 can break up the material bolts moving from bottom to top in the pneumatic blowing channel 53, and change the direction of the material bolts from vertical upward movement to the direction of movement towards the discharge channel 79, so that the broken material bolts can smoothly enter the guide channel 42 and enter the steering auger 3 along the slope of the guide channel 42.

[0043] In one specific embodiment of the present invention, the first rotary power assembly 52 and the second rotary power assembly 62 are combinations of a motor and a pulley reducer. The sliding power assembly 9 is an electric actuator structure.

[0044] The complete working principle and process of this invention are as follows: Reference Figures 3 to 5 When there is sufficient material in the carriage during the initial unloading stage, this device adopts a paddle-push mode. In the paddle-push mode, the first rotary power component 52 drives the rotary shaft 5 to rotate, thereby feeding the material from the bottom of the paddle-push channel 41 into the steering auger 3 connected to the top of the paddle-push channel 41 through the propeller blades 51. At this time, the core tube 7 is in the first position, the third air guide channel 77 is connected to the third air supply connector 43, the venting channel 78 is connected to the jet hole 54, and the discharge channel 79 is isolated from the guide hole 55. The third air supply connector 43 supplies gas to the pneumatic blowing channel 53, and the airflow in the pneumatic blowing channel 53 is sprayed into the paddle-push channel 41 through the jet hole 54 to blow the material on the propeller blades 51 to assist in the material conveying. It is understandable that, in the paddle-push mode, the first rotary power component 52 drives the rotary shaft 5 to rotate continuously, while the core tube 7 remains stationary, and the jet hole 54 and the venting channel 78 will have their positions staggered in the circumferential direction. To ensure that the airflow in the pneumatic blowing channel 53 can be continuously injected into the blade pushing channel 41, an annular second air guide groove 70 is provided on the outer wall of the core tube 7. During the rotation of the rotating shaft 5, the second air guide groove 70 maintains the connection between the jet hole 54 and the ventilation channel 78 through its annular structure design, thereby ensuring the continuity of the airflow injected from the jet hole 54.

[0045] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7When the material in the carriage is insufficient during the later stages of unloading, this device switches to pneumatic blowing mode. In pneumatic blowing mode, the first rotary power component 52 stops driving the rotary shaft 5 to rotate, and the second rotary power component 62 starts driving the rotary seat 61 to rotate. At the same time, the core tube 7 moves from the first position to the second position. At this time, the third air guide channel 77 is isolated from the third air supply connector 43, and the air permeation channel 78 is isolated from the jet hole 54, so that the airflow in the pneumatic blowing channel 53 stops being sprayed into the paddle pushing channel 41; the discharge channel 79 is connected to the guide hole 55, the first air passage 64 is connected to the first air guide groove 76, and the second air guide channel 75 is connected to the second air passage 65 when the rotary seat 61 is in the second rotation position.

[0046] Thus, during the rotation of the rotating seat 61, when the rotating seat 61 rotates to the first rotation position, the temporary storage channel 63 connects with the paddle pushing channel 41, and the material in the paddle pushing channel 41 falls into the temporary storage channel 63 under the action of gravity; subsequently, the rotating seat 61 rotates to the second rotation position, and the temporary storage channel 63 connects with the pneumatic blowing channel 53, and the material in the temporary storage channel 63 falls onto the screen plate 71 at the bottom end of the core tube 7 under the action of gravity through the feeding channel 74. At this time, the first air guiding channel 73 connects to the suction connector 82 in sequence through the first air guiding groove 76 and the first air passage 64, thereby applying negative pressure to the pneumatic blowing channel 53; the second air guiding channel 75 connects to the second air supply connector 83 through the second air passage 65, thereby applying positive pressure to the pneumatic blowing channel 53. Since the second air guide channel 75 is located above the feed channel 74, the temporary storage bin 72 above the screen plate 71 forms a positive pressure zone, and the screen plate 71 below forms a negative pressure zone, generating an air pressure difference. This air pressure difference drives the gas in the pneumatic blowing channel 53 to flow from the positive pressure zone to the negative pressure zone, thereby using air pressure to compact the material on the screen plate 71, making the material form a tight material plug.

[0047] Next, refer to Figure 2 and Figure 6When the rotating seat 61 rotates back to the first rotating position under the action of the second rotating power component 62, the first air guide channel 73 connects to the first air supply connector 81 through the first air guide groove 76 and the first air passage 64 in sequence. This allows the first air guide channel 73 to apply positive pressure to the pneumatic blowing channel 53, generating an airflow that moves from bottom to top from the screen plate 71 within the pneumatic blowing channel 53, driving the material plugs on the screen plate 71 upwards. At this time, the second air passage 65 is isolated from the second air supply connector 83, preventing the material plugs from being blown apart by the radial airflow generated by the second air passage 65 as they pass from bottom to top. This would damage their dense structure, causing the material plugs to break into discrete particles, changing from dense phase conveying to dilute phase conveying, significantly increasing energy consumption and reducing conveying efficiency. In addition, it also prevents two positive pressure airflows from flowing into the pneumatic blowing channel 53 simultaneously, which would cause flow field turbulence. At the same time, the temporary storage channel 63 is reconnected with the paddle push channel 41, and the remaining material in the paddle push channel 41 continues to fall into the temporary storage channel 63 under the action of gravity, in preparation for the next rotation position switch of the rotating seat 61.

[0048] Then, refer to Figures 1 to 3 ,as well as Figure 6 and Figure 7 During the rotation of the rotating seat 61, the first air guide channel 73 and the second air guide channel 75 alternately apply positive pressure to the pneumatic blowing channel 53, so that the material plug that has moved above the second air guide channel 75 is continuously subjected to positive pressure and keeps moving upward, effectively preventing the material plug from sliding back due to interruption of positive pressure.

[0049] When the material bolt moves to the top of the pneumatic conveying channel 53, it hits the guide cone 56. The guide cone 56 breaks it up, and under the guidance of the guide cone 56, the broken material passes through the discharge channel 79 and the guide hole 55 in sequence and enters the guide channel 42. Finally, it slides into the steering auger 3 along the slope of the guide channel 42 to complete the conveying process.
