Description

Technical Field

[0001] This invention relates to auger devices, specifically an auger device for a bulk feed transport vehicle. Background Technology

[0002] The auger system of bulk feed transport trucks typically includes a vertically mounted lifting auger. During the later stages of unloading, especially near the emptying phase of the truck bed, as the amount of material in the bed decreases, the amount of material entering the lifting auger gradually decreases. When the amount of material inside the lifting auger decreases to a certain level, the material column is prone to breakage or excessively low filling rate, disrupting the original conveying mechanical balance. At this point, the pushing force of the auger propeller cannot effectively counteract the downward pull of gravity on the sparse material column, making it difficult to maintain a stable material conveying state. The propeller cannot effectively push the remaining material, causing it to slide down the propeller and form a backflow. This backflow significantly reduces the actual conveying efficiency of the lifting auger. More seriously, the sliding material and the newly entering material at the bottom of the lifting auger are compressed and piled up, forming an "arching" phenomenon, further exacerbating the deterioration of the conveying state.

[0003] Therefore, there is an urgent need for an auger device for bulk feed transport vehicles that can stably transport materials in situations with relatively small quantities. Summary of the Invention

[0004] To overcome the existing technical problems, the present invention provides an auger device for a bulk feed transport vehicle that can stably transport materials under conditions of small material volume.

A blade pushing channel is provided between the outer side wall of the rotating shaft and the inner side wall of the housing. A pneumatic blowing channel is provided inside the rotating shaft. A material guiding channel is connected between the top of the pneumatic blowing channel and the steering auger. A material feeding mechanism is connected to the bottom of the pneumatic blowing channel. The device has a blade pushing mode, in which the first rotary power component drives the rotating shaft to rotate. The device has a pneumatic blowing mode. In the pneumatic blowing mode, an airflow is generated in the pneumatic blowing channel from bottom to top, and the feeding mechanism pushes the material in the paddle pushing channel into the pneumatic blowing channel.

[0007] As a further improvement of the present invention, a core tube is rotatably provided inside the rotating shaft, and a pneumatic blowing channel is provided inside the core tube.

[0008] As a further improvement of the present invention, the feeding mechanism includes a rotating seat rotatably sleeved on the outside of the core tube, and a second rotational power assembly drivenly connected to the rotating seat. The rotating seat is provided with a temporary storage channel and has a first rotation position and a second rotation position. When the rotating seat is in the first rotating position, the temporary storage channel is connected to the blade pushing channel and isolated from the pneumatic blowing channel. When the rotating seat is in the second rotating position, the temporary storage channel is isolated from the blade pushing channel, and the temporary storage channel is connected to the pneumatic blowing channel.

[0009] As a further improvement of the present invention, a sieve plate is provided at the bottom end of the core tube, a temporary storage chamber is formed above the sieve plate, and a first air guide channel is connected below the sieve plate. The sidewall of the core tube has a feeding channel and a second air guiding channel opened sequentially from bottom to top; When the rotating seat is in the first rotating position, the first air guide channel applies positive pressure to the pneumatic blowing channel, and the second air guide channel is closed; When the rotating seat is in the second rotating position, the first air guide channel applies negative pressure to the pneumatic blowing channel, and the second air guide channel applies positive pressure to the pneumatic blowing channel.

[0010] As a further improvement of the present invention, the rotating seat is provided with a first air passage corresponding to the first air guide channel and a second air passage corresponding to the second air guide channel; A support seat is rotatably fitted on the outer side of the rotating seat, and the support seat is provided with a first air supply connector and an air intake connector corresponding to the first air passage. The support base is also equipped with a second air supply connector corresponding to the second air passage; When the rotating seat is in the first rotating position, the first air passage is connected to the first air supply connector, the first air passage is isolated from the air intake connector, and the second air passage is isolated from the second air supply connector. When the rotating seat is in the second rotating position, the first air passage is connected to the air intake connector, the first air passage is isolated from the first air supply connector, and the second air passage is connected to the second air supply connector.

[0011] As a further improvement of the present invention, an annular first air guide groove is provided on the outer wall of the core tube, and the first air guide channel is connected to the first air guide groove.

[0012] As a further improvement of the present invention, a third air guiding channel, an air permeation channel and a material discharge channel are provided on the core tube; The side wall of the rotating shaft is provided with air jet holes corresponding to the ventilation channel and material guide holes corresponding to the discharge channel; The housing is equipped with a third air supply connector corresponding to the third air guide channel, and the material guide hole is connected to the material guide channel; The core tube is connected to a sliding force assembly, and the core tube has a first vertical position and a second vertical position; When the core tube is in the first position, the third air guide channel is connected to the third air supply connector, the air permeation channel is connected to the air jet hole, and the discharge channel is isolated from the guide hole.

[0013] As a further improvement of the present invention, an annular second air guide groove is provided on the outer wall of the core tube, and the air passage is connected to the second air guide groove.

[0014] As a further improvement of the present invention, the bottom end of the paddle pushing channel is funnel-shaped, the top end of the pneumatic blowing channel is provided with a guide cone, and the guide channel is slope-shaped.

[0015] The beneficial effects of this invention are as follows: When the material in the carriage is sufficient, this device operates in paddle-push mode. In paddle-push mode, the first rotary power component drives the rotating shaft to rotate, thereby feeding the material from the bottom of the paddle-push channel into the steering auger connected to the top of the paddle-push channel via the propeller blades. When the material in the carriage is insufficient, this device switches to pneumatic blowing mode. In pneumatic blowing mode, an airflow moving from bottom to top is generated in the pneumatic blowing channel. At the same time, the feeding mechanism feeds the material in the paddle-push channel into the pneumatic blowing channel, causing the material to be carried upward by the airflow and finally enter the steering auger through the guide channel. It can be seen that this device effectively avoids the problems of material slippage, backflow, and blockage when the material quantity is small, and achieves stable conveying under conditions of small material quantity.

Detailed implementation manners

[0019] ]>The drawings are only for illustrative purposes and should not be construed as limitations on this patent; for better illustration of this embodiment, some components in the drawings may be omitted, enlarged or reduced, which do not represent the dimensions of the actual product.

[0020] For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. The technical solutions of the present invention will be further described below with reference to the drawings and embodiments.

[0021] Referring to Figures 1 to 7 , the present invention provides a screw device for a bulk feed transport vehicle, which device includes an oriented auger 1, a lifting auger 2 and a steering auger 3 connected in sequence. The lifting auger 2 includes a housing 4 extending vertically, a rotating shaft 5 rotatably disposed in the housing 4, a spiral blade 51 integrally disposed on the outer side wall of the rotating shaft 5, and a first rotating power component 52 drivingly 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. An air blowing channel 53 is provided inside the rotating shaft 5. A feeding channel 42 is connected between the top end of the air blowing channel 53 and the steering auger 3. The bottom end of the air blowing channel 53 is connected to a feeding mechanism 6; The device has a blade pushing mode. In the blade pushing mode, the first rotary power component 52 drives the rotating shaft 5 to rotate; The device has an air blowing mode. In the air blowing mode, an air flow moving from bottom to top is generated in the air blowing channel 53, and the feeding mechanism 6 feeds the material in the blade pushing channel 41 into the air blowing channel 53.

[0022] In the early stage of unloading, there is sufficient material in the carriage, and the device is in the blade pushing mode. In the blade pushing mode, the first rotary power component 52 drives the rotating shaft 5 to rotate, and then the material is fed from the bottom end of the blade pushing channel 41 into the steering auger 3 connected to the top end of the blade pushing channel 41 through the spiral blade 51. In the later stage of unloading, there is insufficient material in the carriage, and the device switches to the air blowing mode. In the air blowing mode, an air flow moving from bottom to top is generated in the air blowing channel 53. At the same time, the feeding mechanism 6 feeds the material in the blade pushing channel 41 into the air blowing channel 53, so that the material is carried upward by the air flow and finally enters the steering auger 3 through the feeding channel 42.

[0023] It can be understood that through the working condition adaptation design of adopting the blade pushing mode when the material is sufficient and switching to the air blowing mode when the material is insufficient, the device not only realizes efficient large-flow transportation relying on the mechanical pushing force of the spiral blade 51 in the stage of sufficient material, but also can offset the downward pulling effect of gravity on the sparse material column through the air flow entrainment effect in the stage of insufficient material, effectively avoiding problems such as material sliding, backflow and blockage. In this way, not only the unloading efficiency is guaranteed, but also the stable transportation of the material throughout the whole cycle from sufficient to exhausted is realized, greatly improving the operation adaptability and overall operation efficiency of the bulk feed transport vehicle.

[0024] Refer to Figures 1 to 3 It can be seen that a core tube 7 is rotatably provided inside the rotating shaft 5, and the air blowing channel 53 is provided inside the core tube 7.

[0025] Refer to Figures 1 to 3 、以及 Figure 6 和 Figure 7 It can be seen that the feeding mechanism 6 includes a rotating seat 61 rotatably sleeved outside the core tube 7, and a second rotary power component 62 drivingly connected to the rotating seat 61. A temporary storage channel 63 is provided on the rotating seat 61, 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 communicated with the blade pushing channel 41, and the temporary storage channel 63 is isolated from the air blowing channel 53; When the rotating seat 61 is in the second rotation 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 conveying channel 53.

[0026] When the material is insufficient, the first rotation power component 52 stops driving the rotating shaft 5 to rotate, and the second rotation power component 62 starts to drive the rotating seat 61 to rotate. When the rotating seat 61 rotates to the first rotation position, the temporary storage channel 63 is connected to the blade pushing channel 41, and the material in the blade 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, the temporary storage channel 63 is connected to the pneumatic conveying channel 53, and the material in the temporary storage channel 63 falls into the pneumatic conveying channel 53 under the action of gravity, and then is carried upward by the air flow in the pneumatic conveying channel 53 and finally enters the turning auger 3 through the material guiding channel 42. The rotating seat 61 cyclically switches between the first rotation position and the second rotation position, and continuous pneumatic conveying of materials can be achieved.

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

[0028] Refer to Figures 1 to 3 、以及 Figure 6 和 Figure 7 It can be seen that a sieve plate 71 is provided at the bottom end of the core pipe 7, a temporary storage bin 72 is formed above the sieve plate 71, and a first air guiding channel 73 is connected below the sieve plate 71; The side wall of the core pipe 7 is successively provided with a feed channel 74 and a second air guiding channel 75 from bottom to top; When the rotating seat 61 is in the first rotation position, the first air guiding channel 73 applies a positive pressure to the pneumatic conveying channel 53, and the second air guiding channel 75 is closed; When the rotating seat 61 is in the second rotation position, the first air guiding channel 73 applies a negative pressure to the pneumatic conveying channel 53, and the second air guiding channel 75 applies a positive pressure to the pneumatic conveying channel 五三.

[0029] When the rotating seat 61 is in the second rotating position, the material in the temporary storage channel 63 falls onto the sieve plate 71 at the bottom end of the core pipe 7 under the action of gravity through the feeding channel 74. At this time, based on the fact that the second air guiding channel 75 is above the feeding channel 74, the first air guiding channel 73 applies a negative pressure to the pneumatic conveying channel 53, and the second air guiding channel 75 applies a positive pressure to the pneumatic conveying channel 53, a positive pressure area is formed in the temporary storage bin 72 above the sieve plate 71, and a negative pressure area is formed below the sieve plate 71, generating a pressure difference; this pressure difference drives the gas in the pneumatic conveying channel 53 to flow from the positive pressure area to the negative pressure area, and then compacts the material on the sieve plate 71 by means of the air pressure, so that the material forms a compacted plug, effectively improving the overall compactness of the plug. Subsequently, when the rotating seat 61 rotates to the second rotating position, the first air guiding channel 73 applies a positive pressure to the pneumatic conveying channel 53, generating an upward airflow in the channel, and then entraining the plug above the sieve plate 71 to move upward. It can be understood that during the process of the first air guiding channel 73 applying a positive pressure to the pneumatic conveying channel 53, the second air guiding channel 75 is synchronously closed, which can prevent the plug from being blown and cracked by the radial airflow generated by it when passing through the second air guiding channel 75 from bottom to top, thus preventing the plug from breaking into discrete particles and avoiding the change of the conveying state from dense-phase conveying to dilute-phase conveying, thereby eliminating 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 guiding channel 73 and the second air guiding channel 75 alternately apply a positive pressure to the pneumatic conveying channel 53, so that the plug that has moved above the second air guiding channel 75 continuously receives the positive pressure and maintains the upward movement state, effectively avoiding the reverse flow of the plug caused by the interruption of the positive pressure, and further ensuring the conveying stability.

[0031] It should be noted that the improvement of the plug compactness has the following advantages: First, it can enhance the "pushing efficiency" of the airflow in the subsequent pneumatic conveying channel 53 on the material - the kinetic energy of the airflow can act on the whole plug concentratedly, avoiding the penetration of the airflow and the waste of kinetic energy due to the overly loose material, thus reducing the reverse flow loss of the material due to gravity sliding and significantly increasing the actual conveying volume; Second, the overall suspension resistance of the compacted material mass is more stable, and it can maintain the vertical upward movement without relying on too high wind speed. This can not only reduce the energy consumption of the fan, but also avoid the flow field disorder (such as eddy current, stratification) caused by the high - speed airflow, reduce the risk of deposition and blockage in the pneumatic conveying channel 53, and improve the conveying continuity; Third, the compacted plug is not easily blown away by the airflow, which can greatly reduce the dust raising caused by the upward movement of the airflow during the vertical conveying, reduce the material loss and environmental cross - pollution, and the overall movement of the material mass has a more uniform friction with the pipe wall of the pneumatic conveying channel 53, avoiding the aggravated wear caused by local high - speed impact and extending the equipment life.

[0032] Refer to Figure 1-7, the rotating seat 61 is provided with a first air passage 64 corresponding to the first air guiding passage 73 and a second air passage 65 corresponding to the second air guiding passage 75; A support seat 8 is rotatably sleeved on the outer side of the rotating seat 61. The support seat 8 is provided with a first air supply joint 81 and a suction joint 82 corresponding to the first air passage 64; The support seat 8 is further provided with a second air supply joint 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 communicated with the first air supply joint 81, the first air passage 64 is isolated from the suction joint 82, and the second air passage 65 is isolated from the second air supply joint 83; When the rotating seat 61 is in the second rotating position, the first air passage 64 is communicated with the suction joint 82, the first air passage 64 is isolated from the first air supply joint 81, and the second air passage 65 is communicated with the second air supply joint 83.

[0033] When the rotating seat 61 is in the first rotating position, the first air passage 64 is communicated with the first air supply joint 81 to generate an upward-moving air flow in the pneumatic conveying passage 53. At this time, the first air passage 64 is isolated from the suction joint 82 to prevent the air flow in the pneumatic conveying passage 53 from flowing out through the suction joint 82, and thus an upward-moving air flow cannot be generated in the pneumatic conveying passage 53. The second air passage 65 is isolated from the second air supply joint 83 to prevent the material plug from being blown apart by the radial air flow generated by the second air passage 65 when passing through the second air passage 65 from bottom to top, destroying its dense structure, resulting in the fragmentation of the material plug 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 air flows from flowing into the pneumatic conveying passage 53 at the same time, resulting in flow field disorder.

[0034] When the rotating seat 61 is in the second rotating position, the first air passage 64 is communicated with the suction joint 82, and then the suction joint 82 is communicated with the first air guiding passage 73, so that the first air guiding passage 73 applies a negative pressure to the pneumatic conveying passage 53. The second air passage 65 is communicated with the second air supply joint 83, and then the second air supply joint 83 is communicated with the second air guiding passage 75, so that the second air guiding passage 75 applies a positive pressure to the pneumatic conveying passage 53.

[0035] Refer to Figure 6 and Figure 7 , an annular first air guiding groove 76 is formed on the outer side wall of the core pipe 7, and the first air guiding passage 73 is communicated with the first air guiding groove 76.

[0036] When the core tube 7 is in the second position, the arrangement of the first air guide groove 76 enables the first air passage 64 to communicate with the first air guide groove 76 every time the rotating seat 61 rotates 180 degrees, so that the first air guide passage 73 can communicate with the first air supply joint 81 or the suction joint 82. At this time, 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, a third air guide passage 77, a breathable passage 78 and a discharge passage 79 are provided on the core tube 7; The side wall of the rotating shaft 5 is provided with an air jet hole 54 corresponding to the breathable passage 78 and a material guiding hole 55 corresponding to the discharge passage 79; The housing 4 is provided with a third air supply joint 43 corresponding to the third air guide passage 77, and the material guiding hole 55 communicates with the material guiding passage 42; The core tube 7 is connected with a sliding power component 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 passage 77 communicates with the third air supply joint 43, the breathable passage 78 communicates with the air jet hole 54, and the discharge passage 79 is isolated from the material guiding hole 55; When the core tube 7 is in the second position, the third air guide passage 77 is isolated from the third air supply joint 43, the breathable passage 78 is isolated from the air jet hole 54, and the discharge passage 79 communicates with the material guiding hole 55.

[0038] When the material is sufficient, the device operates in the paddle pushing mode. To further improve the material conveying efficiency in the paddle pushing mode, at this time, the core tube 7 is in the first position, the third air guide passage 77 communicates with the third air supply joint 43, the breathable passage 78 communicates with the air jet hole 54, the third air supply joint 43 conveys gas into the pneumatic blowing passage 53, and the air flow in the pneumatic blowing passage 53 jets through the air jet hole 54 into the paddle pushing passage 41 to blow the material on the spiral paddle 51, which is beneficial to the conveying of the material.

[0039] [[ID=十九]]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 breathable passage 78 communicates with the second air guide groove 70.

[0040] When in the paddle pushing mode, the first rotation power component 52 will drive the rotating shaft 5 to rotate continuously, while the core tube 7 remains stationary. At this time, the air jet hole 54 and the breathable passage 78 will be arranged in an alternating manner. In order to ensure that the air flow in the pneumatic blowing passage 53 can continuously jet into the paddle pushing passage 41, the second air guide groove 70 is provided, which can keep the breathable passage 78 communicating with the second air guide groove 70 during the rotation of the rotating shaft 5.

[0041] As a further improvement of the present invention, the bottom end of the blade pushing channel 41 is trumpet-shaped, a material guiding cone 56 is provided at the top end of the pneumatic conveying channel 53, and the material guiding channel 42 is in a slope shape.

[0042] The trumpet shape helps the material in the blade pushing channel 41 to fall into the temporary storage channel 63 under the action of gravity. Similarly, the setting of the material guiding cone 56 can break up the material plug moving from bottom to top in the pneumatic conveying channel 53, and convert the moving direction of the material plug from vertically upward to the moving direction towards the discharge channel 79, so that the broken-up material plug can smoothly enter the material guiding channel 42 and enter the turning auger 3 along the slope of the material guiding channel 42.

[0043] As a specific embodiment of the present invention, the first rotating power component 52 and the second rotating power component 62 are a combination of a motor and a belt pulley reducer. The sliding power component 9 is an electric push rod structure.

[0044] The complete working principle and process of the present invention are as follows: Refer to [[ID=??]] Figures 3 to 5 When there is sufficient material in the carriage during the early stage of unloading, the device adopts the blade pushing mode. In the blade pushing mode, the first rotating power component 52 drives the rotating shaft 5 to rotate, and then the material is sent from the bottom end of the blade pushing channel 41 into the turning auger 3 connected to the top end of the blade pushing channel 41 through the spiral blade 51. At this time, the core pipe 7 is in the first position, the third air guiding channel 77 is connected to the third air supply joint 43, the air permeable channel 78 is connected to the air spraying hole 54, and the discharge channel 79 is isolated from the material guiding hole 55. The third air supply joint 43 conveys gas into the pneumatic conveying channel 53, and the air flow in the pneumatic conveying channel 53 sprays towards the blade pushing channel 41 through the air spraying hole 54 to blow the material on the spiral blade 51 to assist in the conveying of the material. It can be understood that since in the blade pushing mode, the first rotating power component 52 will drive the rotating shaft 5 to continuously rotate while the core pipe 7 remains stationary, the air spraying hole 54 and the air permeable channel 78 will be staggered in the circumferential direction. In order to ensure that the air flow in the pneumatic conveying channel 53 can continuously spray towards the blade pushing channel 41, a ring-shaped second air guiding groove 70 is provided on the outer side wall of the core pipe 7. During the rotation of the rotating shaft 5, the second air guiding groove 70 maintains the conduction state of the air spraying hole 54 and the air permeable channel 78 through the ring-shaped structure design, so as to ensure the continuity of the air flow sprayed from the air spraying hole 54.

[0045] Refer to Figure 1 、 Figure 2 、 Figure 6 和 Figure 7 It seems there is an incorrect reference tag which says "参照" without a proper ID number following it in the original. I've left it as is in the translation. Also, there is an incorrect reference tag with the same "参照" text. Please check the original text for accuracy., when there is insufficient material in the carriage during the later stage of discharging, the device switches to the pneumatic conveying mode. In the pneumatic conveying 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 pipe 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 joint 43, and the air permeable channel 78 is isolated from the air injection hole 54, so that the air flow in the pneumatic conveying channel 53 stops jetting towards the blade pushing channel 41; the discharge channel 79 is connected to the material guiding hole 55, the first air passing channel 64 is connected to the first air guide groove 76, and the second air guide channel 75 is connected to the second air passing channel 65 when the rotary seat 61 is in the second rotation position.

[0046] In this way, during the rotation of the rotary seat 61, when the rotary seat 61 rotates to the first rotation position, the temporary storage channel 63 is connected to the blade pushing channel 41, and the material in the blade 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, the temporary storage channel 63 is connected to the pneumatic conveying channel 53, and the material in the temporary storage channel 63 falls onto the sieve plate 71 at the bottom end of the core pipe 7 under the action of gravity through the feeding channel 74. At this time, the first air guide channel 73 is sequentially connected to the suction joint 82 through the first air guide groove 76 and the first air passing channel 64, so that the first air guide channel 73 applies a negative pressure to the pneumatic conveying channel 53; the second air guide channel 75 is connected to the second air supply joint 83 through the second air passing channel 65, so that the second air guide channel 75 applies a positive pressure to the pneumatic conveying channel 53. Based on the fact that the second air guide channel 75 is above the feeding channel 74, a positive pressure area is formed in the temporary storage bin 72 above the sieve plate 71, and a negative pressure area is formed below the sieve plate 71, generating an air pressure difference; this air pressure difference drives the gas in the pneumatic conveying channel 53 to flow from the positive pressure area to the negative pressure area, and then compacts the material on the sieve plate 71 by means of air pressure, making the material form a compacted material plug.

[0047] Then, refer to Figure 2 and Figure 6, when the rotating seat 61 rotates back to the first rotation position under the action of the second rotation power component 62, the first air guide channel 73 is sequentially connected to the first air supply joint 81 through the first air guide groove 76 and the first air passage 64, so that the first air guide channel 73 applies a positive pressure to the pneumatic conveying channel 53, generating an upward-moving airflow in the pneumatic conveying channel 53 starting from the sieve plate 71, which drives the material plug on the sieve plate 71 to move upward. At this time, the second air passage 65 is isolated from the second air supply joint 83, preventing the material plug from being blown apart by the radial airflow generated by the second air passage 65 when passing through the second air passage 65 from bottom to top, damaging 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 conveying channel 53 simultaneously, resulting in a disordered flow field. Meanwhile, the temporary storage channel 63 is connected to the blade pushing channel 41 again, and the remaining material in the blade pushing channel 41 continues to fall into the temporary storage channel 63 under the action of gravity, waiting for the next rotation position switching of the rotating seat 61.

[0048] After that, referring to Figures 1 to 3 , as well as Figure 6 and <color red> 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 conveying channel 53, so that the material plug that has moved above the second air guide channel 75 continues to be under the action of positive pressure and maintains an upward-moving state, effectively preventing the material plug from sliding back due to the interruption of positive pressure.

[0049] When the material plug moves to the top of the pneumatic conveying channel 53 and impacts the material guiding cone 56, after being dispersed by the material guiding cone 56, under the guidance of the material guiding cone 56, the dispersed material sequentially enters the material guiding channel 42 through the discharge channel 79 and the material guiding hole 55, and finally slides down along the slope of the material guiding channel 42 into the turning auger 3 to complete the conveying process.
