Description

Technical Field

[0001] This invention belongs to the field of anchor bolt technology, specifically a multi-point unloading conveyor. Background Technology

[0002] A tubular chain conveyor is a continuous conveying equipment for transporting bulk materials such as powders, small granules, and small lumps. It can transport materials horizontally, inclined, and vertically in combination. It is generally used in loading and unloading of fine chemicals, pesticides, ores, and building materials. It is especially important for the transportation of powdery materials, as tubular chain conveyors can effectively ensure the sealing of the material transportation process.

[0003] In existing conveyors, material is fed into the feed head during loading and unloading. Inside the conveying pipe, a pusher plate, driven by a chain, moves the material within the pipe, and then it is discharged through the discharge head. To improve loading and unloading efficiency, designers typically add multiple auxiliary feed ports to the surface of the conveying pipe. When the conveyor is transporting material, workers open these auxiliary feed ports to add material, thus increasing the conveyor's efficiency. However, in actual operation, when workers open the auxiliary feed ports and add material, the material inside the conveying pipe is pushed by the pusher plate. When foreign material enters the pipe, the pusher plate impacts the material, easily causing it to be knocked out of the auxiliary feed ports, resulting in material waste and hindering stable material addition.

[0004] Therefore, the present invention provides a multi-point unloading conveyor. Summary of the Invention

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 6 As shown, a multi-point unloading conveyor according to an embodiment of the present invention includes a conveying pipe 1, a feeding head 11 is provided at one end of the conveying pipe 1, a discharging head 12 is provided at the other end of the conveying pipe 1, a partition 13 is provided inside the conveying pipe 1, a plurality of pusher plates 14 are provided on the upper and lower sides of the partition 13, and a pair of chains 15 are provided between the pusher plates 14.

[0033] The top surface of the feeding pipe 1 has multiple feeding notches 2. The top of the feeding notch 2 is provided with a feeding pipe 21. A first partition 22 is inserted through the side of the feeding pipe 21. A first telescopic rod 23 is provided on the side of the feeding pipe 21. A first connecting frame is provided between the output end of the first telescopic rod 23 and the end of the first partition 22. A second partition 24 is inserted through the side of the feeding pipe 21 and above the first partition 22. A second telescopic rod 25 is provided on the side of the feeding pipe 21 and above the first partition 22. A second connecting frame is provided between the output end of the second telescopic rod 25 and the end of the second partition 24. When the first partition 22 and the second partition 24 are fully inserted into the feeding pipe 21, they can both isolate the internal space of the feeding pipe 21. A feeding funnel 3 is provided at the top of the feeding pipe 21 and is connected to the feeding pipe 21.

[0034] In this embodiment of the invention, when the conveyor is started, the operator adds material to the feed head 11. The material is pushed by the pusher plate 14 moving inside the feed pipe 1. The pusher plate 14, in conjunction with the partition plate 13, conveys the material to the discharge head 12, and then discharges it through the outlet inside the discharge head 12. Next, the operator adds material to the feed hopper 3. The material falls downwards into the feed pipe 21 and is received by the second partition plate 24. Then, the second telescopic rod 25 is activated. The second telescopic rod 25 drives the second partition plate 24 to move through the second connecting frame. The second partition plate 24 is gradually pulled out of the feed pipe 21, and the material received on the top surface of the second partition plate 24 falls downwards onto the top surface of the first partition plate 22. Then, the second telescopic rod... Rod 25 drives the second partition 24 to reset via the second connecting frame, and the second partition 24 isolates the feed pipe 21; then the first telescopic rod 23 is activated, and the first telescopic rod 23 drives the first partition 22 to gradually detach from the feed pipe 21 via the first connecting frame. The material received on the top surface of the first partition 22 falls downward and enters the conveying pipe 1 through the feeding notch 2. During the feeding process, the second partition 24 blocks the feed pipe 21 to prevent the material from being impacted and detaching from the feed pipe 21. Throughout the process, the first partition 22 and the second partition 24 move back and forth to realize the feeding process of the material. This can prevent the material from being impacted and detaching from the feed pipe 21 and then from the feed funnel 3, thus avoiding waste and facilitating stable feeding and addition of the material.

[0035] Both the first partition 22 and the second partition 24 are provided with rubber sheets on their side surfaces; the feed pipe 21 has a rectangular hole on its side for the first partition 22 and the second partition 24 to pass through; when the first partition 22 and the second partition 24 move relative to the feed pipe 21, the rubber sheets provided on the side surfaces of the first partition 22 and the second partition 24 fully fill the gap between the first partition 22 and the second partition 24 and the rectangular hole on the side of the feed pipe 21, reducing the probability of material leakage through the gap between the first partition 22 and the second partition 24 and the rectangular hole.

[0036] The first partition 22 and the second partition 24 are both located inside the feed pipe 21 and are both set with pointed ends. When the first partition 22 and the second partition 24 move to reset and separate the feed pipe 21, the pointed ends of the first partition 22 and the second partition 24 squeeze the material in the feed pipe 21. In this process, the pointed ends divide the material and reduce the material's obstruction to the movement of the first partition 22 and the second partition 24.

[0037] like Figures 5 to 8As shown, a rotating shaft 31 is provided through the side of the feeding hopper 3. Multiple stirring rods 32 are evenly arranged on the annular circumference of the rotating shaft 31. A drive motor is provided on the side of the feeding hopper 3. The output end of the drive motor is connected to the end of the rotating shaft 31. When the operator adds material into the feeding hopper 3, the drive motor is started. The drive motor drives the rotating shaft 31 to rotate. The rotating shaft 31 drives the stirring rods 32 on the side to rotate. The material entering the feeding hopper 3 is stirred by the rotating stirring rods 32, thereby driving the material to fall downwards, avoiding the material from accumulating in the feeding hopper 3 and being difficult to fall downwards.

[0038] The stirring rod 32 has a sliding cavity 33 inside, and an impact block 34 is slidably connected inside the sliding cavity 33. A spring 35 is provided between the side of the impact block 34 and the inner wall of the sliding cavity 33. When adding materials with high moisture content, some materials will adhere to the surface of the rotating shaft 31 and the stirring rod 32. Therefore, the drive motor is set to have variable speed output, so that the rotating shaft 31 rotates at different speeds. Thus, the centrifugal force on the stirring rod 32 changes synchronously. When the centrifugal force on the impact block 34 changes, the degree of tension on the spring 35 changes synchronously. The impact block 34 intermittently impacts the inner wall of the sliding cavity 33, causing the stirring rod 32 to oscillate, which in turn drives the rotating shaft 31 to oscillate synchronously. The rotating shaft 31 and the stirring rod 32 accelerate the shedding of surface materials through oscillation force, which helps to improve the effect of driving the material to fall.

[0039] like Figures 4 to 9 As shown, a rectangular suction head 4 is provided at the top of the feeding funnel 3, surrounding the feeding funnel 3. Multiple feeding holes 41 are provided on the top surface of the rectangular suction head 4, and multiple support pipes 42 are provided through the bottom surface of the rectangular suction head 4. A suction pump 43 is connected to the bottom end of each support pipe 42, and the output end of the suction pump 43 is connected to the conveying pipe 1. When in use, the suction pump 43 is activated, drawing air from the rectangular suction head 4 through the support pipes 42. The rectangular suction head 4 absorbs the air at the top of the feeding funnel 3 through the feeding holes 41. When material is added to the feeding funnel 3, the powdery material that escapes is drawn into the feeding holes 41 along with the air, and then discharged into the conveying pipe 1 through the rectangular suction head 4, support pipes 42, and suction pump 43, thus realizing the recovery of the powdery material that has escaped into the air and reducing material waste.

[0040] An extension tube 44 is inserted inside the feed hole 41. Multiple through holes are evenly opened on the surface of the extension tube 44. The through holes on the extension tube 44 increase the air suction area, so that the suction force does not need to be too large to absorb the material that has escaped into the air, and avoid the material in the feed funnel 3 being sucked in by the excessive suction force of the through holes.

[0041] The top of the feed hopper 3 is provided with an insertion slot 5, and an extension frame 51 is inserted into the insertion slot 5. When in use, the extension frame 51 is inserted into the insertion slot 5, and the staff adds a large amount of material into the extension frame 51. The extension frame 51 can fully receive the material, avoiding the staff from continuously adding material into the feed hopper 3 and increasing the workload.

[0042] A rectangular jet nozzle 52 is provided at the top of the extension frame 51, with the jet nozzle of the rectangular jet nozzle 52 pointing towards the inner wall of the extension frame 51. A jet pump 53 is provided on the side of the extension frame 51, and a conduit is provided between the output end of the jet pump 53 and the rectangular jet nozzle 52. When cleaning the material attached to the inner wall of the extension frame 51, airflow is sprayed into the rectangular jet nozzle 52 through the jet pump 53 and the conduit. The airflow acts on the inner wall of the extension frame 51, driving the material attached to the inner wall of the extension frame 51 downward into the feed funnel 3. Then, the airflow continues to drive the material on the inner wall of the feed funnel 3 and the feed pipe 21 into the conveying pipe 1, thereby cleaning the material attached to the inner walls of the extension frame 51, the feed funnel 3, and the feed pipe 21.

[0043] A vibrator 54 is provided on the side of the extension frame 51. When cleaning the material adhering to the inner wall of the extension frame 51, the feeding funnel 3, and the feeding pipe 21, the vibrator 54 is activated. The vibrator 54 causes the material adhering to the inner wall of the extension frame 51, the feeding funnel 3, and the feeding pipe 21 to fall off, thereby improving the effect and efficiency.

[0044] During operation, the conveyor is started, and the operator adds material to the feed head 11. The material is pushed by the pusher plate 14 inside the feed pipe 1, which, together with the partition plate 13, conveys the material to the discharge head 12, and then discharges it through the outlet inside the discharge head 12. Next, the operator adds material to the feed hopper 3, which falls downwards into the feed pipe 21 and is caught by the second partition plate 24. Then, the second telescopic rod 25 is activated, moving the second partition plate 24 through the second connecting frame. The second partition plate 24 is gradually pulled out of the feed pipe 21, and the material caught on the top surface of the second partition plate 24 falls downwards onto the top surface of the first partition plate 22. Then, the second telescopic rod 25, through the second connecting frame, resets the second partition plate 24, which then blocks the feed pipe 21. Finally, the first telescopic rod 23 is activated, moving through the first connecting frame... The first partition 22 gradually detaches from the feed pipe 21, and the material received on the top surface of the first partition 22 falls downward and enters the conveying pipe 1 through the feeding notch 2. During the feeding process, the second partition 24 blocks the feed pipe 21 to prevent the material from being impacted and detaching from the feed pipe 21. Throughout the process, the first partition 22 and the second partition 24 move back and forth to realize the feeding process of the material. This can prevent the material from being impacted and detaching from the feed pipe 21 and then from the feed funnel 3, thus avoiding waste and facilitating stable feeding and addition of the material. When the first partition 22 and the second partition 24 move relative to the feed pipe 21, the rubber sheets set on the side surfaces of the first partition 22 and the second partition 24 fully fill the gaps between the first partition 22 and the second partition 24 and the rectangular holes on the side of the feed pipe 21, reducing the probability of material leakage through the gaps between the first partition 22 and the second partition 24 and the rectangular holes.

[0045] When the first partition 22 and the second partition 24 move to reset and separate the feed pipe 21, the pointed parts of the first partition 22 and the second partition 24 squeeze the material in the feed pipe 21. During this process, the pointed parts divide the material, reducing the material's obstruction to the movement of the first partition 22 and the second partition 24. When the operator adds material into the feed funnel 3, the drive motor is started, which drives the rotating shaft 31 to rotate. The rotating shaft 31 drives the agitator 32 on the side to rotate. The material entering the feed funnel 3 is agitated by the rotating agitator 32, which in turn drives the material to fall downwards. For materials with high moisture content, some material will adhere to the surface of the rotating shaft 31 and the agitator 32 when added. Therefore, the drive motor is set to variable speed output, so that the rotating shaft 31 rotates at a different speed. Thus, the centrifugal force on the agitator 32 changes synchronously, and the impact block 34 is subjected to centrifugal force. When the tension of the spring 35 changes, the impact block 34 intermittently impacts the inner wall of the sliding cavity 33, causing the stirring rod 32 to oscillate, which in turn drives the rotating shaft 31 to oscillate synchronously. The rotating shaft 31 and the stirring rod 32 accelerate the shedding of surface material through the oscillation force. When in use, the air pump 43 is started. The air pump 43 draws air from the rectangular air head 4 through the support pipe 42. The rectangular air head 4 absorbs the air at the top of the feeding funnel 3 through the feed hole 41. When adding material into the feeding funnel 3, the powdery material that escapes is sucked into the feed hole 41 along with the air, and then discharged into the conveying pipe 1 through the rectangular air head 4, the support pipe 42, and the air pump 43. The through hole on the extension pipe 44 increases the suction area for air, so that the suction force does not need to be too large to absorb the material that has escaped into the air, and avoids the material in the feeding funnel 3 being sucked in by the excessive suction force of the through hole.

[0046] In operation, the extension frame 51 is inserted into the insertion slot 5. Workers add a large amount of material to the extension frame 51, which can fully accommodate the material, avoiding the need for workers to continuously add material to the feed funnel 3, thus reducing workload. When cleaning the material adhering to the inner wall of the extension frame 51, airflow is sprayed into the rectangular air nozzle 52 via the jet pump 53 and conduit. The airflow acts on the inner wall of the extension frame 51, driving the material adhering to it downwards into the feed funnel 3. The airflow then continues to drive the material on the inner wall of the feed funnel 3 and feed pipe 21 into the conveying pipe 1, thus cleaning the material adhering to the inner walls of the extension frame 51, feed funnel 3, and feed pipe 21. During the cleaning process, the vibrator 54 is activated, causing the material adhering to the inner walls of the extension frame 51, feed funnel 3, and feed pipe 21 to detach, improving both effectiveness and efficiency.
