Technical Field

[0001] This invention relates to the field of material conveying technology, and in particular to an automated conveying device. Background Technology

[0002] As my country's industrialization continues to advance, in order to save labor costs and improve production efficiency, a large amount of raw materials in the construction, industry, and agriculture sectors are now transported automatically by machinery. Consequently, various belt, rail, and tubular conveying devices have emerged. However, with the deepening of my country's industrialization and the rapid development of its economy and society, higher demands are being placed on the automated transportation of raw materials in various industries. These demands include, but are not limited to, longer transportation distances, higher transportation efficiency, stronger adaptability, and stricter environmental protection requirements. Therefore, this presents new challenges and development directions for existing automated material conveying devices.

[0003] In realizing this invention, the aim is to develop an automated conveying device that adapts to new requirements, solves a series of needs and problems such as long distance, large capacity and high efficiency, minimizes the waste of labor and material resources, and improves production efficiency. Summary of the Invention

[0004] The present invention aims to develop an automated conveying device that meets new requirements, solves a series of needs and problems such as long distance, large capacity and high efficiency, minimizes the waste of labor and material resources, and improves production efficiency. The present invention provides an automated transportation device.

[0005] This invention provides an automated transport device, which adopts the following technical solution:

[0006] An automatic conveying device includes a hopper, several standard spiral conveying pipes, several series joints, and a discharge port. The series joints include direct joints and arbitrary angle joints. Flanges for connecting the standard spiral conveying pipes are provided at both ends of each joint. Each standard spiral conveying pipe consists of a main shaft, spiral blades, a seamless steel pipe, a front flange, an end flange, a transmission gear, a bearing support, a hydraulic motor, and a reducer. The main shaft passes through the seamless steel pipe and simultaneously passes through the transmission gear and the bearing support, and is fixedly connected to the transmission gear. The spiral blades are welded to the main shaft along their entire length. The transmission gear is located near the front end of the seamless steel pipe and is fixedly connected to the main shaft in the middle via spokes. The bearing support is fixed to the end of the seamless steel pipe and has a roller bearing at its center. The hydraulic motor is fixed to the outside of the seamless steel pipe and is connected to the transmission gear. The reducer is placed between the transmission gear and the hydraulic motor.

[0007] An adjusting box is fixedly installed at the discharge end of the hopper, and a feeding connector is fixedly installed at the outlet end of the adjusting box. The feeding connector can be connected to a standard spiral conveying pipe through a flange. A threaded rod is rotatably connected inside the adjusting box, and a driving mechanism is connected to the threaded rod. A threaded block is threadedly connected to the outer surface of the threaded rod. A first connecting rod is hinged to one side of the threaded rod, and an adjusting plate is hinged to the end of the first connecting rod away from the threaded rod. One side of the adjusting plate is rotatably connected to the inner wall of the adjusting box through a rotating shaft. A first sliding mechanism is provided on the side of the threaded block away from the first connecting rod.

[0008] The bottom of the feed connector is fixedly installed with an equipment box directly below the regulating box. A first spring is fixedly installed on the inner side wall of the equipment box. A moving block is fixedly installed at one end of the first spring. A second connecting rod is hinged to the top of the moving block. A gravity plate is hinged to the end of the second connecting rod away from the moving block. A gravity sensor is fixedly installed on the inner bottom wall of the equipment box. A controller is fixedly installed at the bottom of the equipment box. A second sliding mechanism is provided on the side of the moving block away from the second connecting rod.

[0009] By adopting the above technical solution, the conveying device is assembled from several standard units, making the conveying equipment more compact and simpler. This facilitates installation, disassembly, and transportation, and it can adapt to different working environments and conditions. Furthermore, the power transmission of the conveying device adopts a distributed arrangement, making its power output more stable and efficient, and enabling the conveying device to achieve longer-distance transportation. Simultaneously, the transported materials are transported through closed pipelines, preventing accidental spillage that could cause personal injury or property damage, thus providing higher safety. In addition, sealed transportation effectively controls dust pollution and irritating odors, resulting in greater environmental friendliness.

[0010] Optionally, a second spring is fixedly installed inside the equipment box, and a pressing block is fixedly installed at one end of the second spring. The pressing block extends through to the outside of the equipment box. A support rod is fixedly installed on the side of the pressing block near the second spring. A third spring is fixedly installed inside the pressing block, and a locking block is fixedly installed at one end of the third spring. A locking groove adapted to the locking block is opened inside the equipment box.

[0011] By adopting the above technical solution, during use, the operator can squeeze the second spring upwards through the squeezing block to retract the second spring. At the same time, the third spring can push the locking block to fix itself to the locking slot inside the equipment box, thereby fixing the squeezing block. The support rod on the squeezing block can contact the gravity plate and press against the gravity plate, preventing the gravity plate from contacting the gravity sensor, thus closing the gravity adjustment structure.

[0012] Optionally, the drive mechanism includes a motor, which is fixedly connected to the outer surface of the regulating box. A first bevel gear is fixedly installed at the output end of the motor through the regulating box. A second bevel gear is meshed with the first bevel gear. The second bevel gear is fixedly connected to a threaded rod. The gravity sensor is electrically connected to the controller, and the controller is electrically connected to the motor.

[0013] By adopting the above technical solution, the motor can drive the first bevel gear to rotate, the first bevel gear can drive the second bevel gear to rotate, and the second bevel gear can drive the threaded rod to rotate, which helps to improve the stability of the threaded rod rotation.

[0014] Optionally, the first sliding mechanism includes a first slider, which is fixedly connected to a threaded block, and the inside of the adjusting box is provided with a first sliding groove that is adapted to the first slider.

[0015] By adopting the above technical solution, the first slider and the first groove can limit the movement range of the threaded block, and at the same time make the movement of the threaded block more stable.

[0016] Optionally, a push rod is fixedly installed on the outer side of the card block, and an elongated sliding hole is opened at the bottom of the compression block, with the push rod extending through the outside of the elongated sliding hole.

[0017] By adopting the above technical solution, the push rod can be easily pushed by the staff to move the block.

[0018] Optionally, a protective shell is fixedly installed on the outer surface of the regulating box, the motor is located inside the protective shell, an installation groove is provided inside the protective shell, and a heat dissipation mesh is fixedly installed on the inner wall of the installation groove inside the protective shell.

[0019] By adopting the above technical solution, the protective shell can protect the motor, reduce the contact between the motor and external objects, and the heat generated by the motor during use can be transferred to the outside through the heat dissipation mesh.

[0020] Optionally, the second sliding mechanism includes a second slider, which is fixedly connected to the moving block, and the interior of the adjusting box is provided with a second sliding groove that is adapted to the second slider.

[0021] By adopting the above technical solution, the second slider and the second slide can limit the movement range of the moving block, and at the same time make the moving block move more smoothly.

[0022] Optionally, the end of the locking block away from the third spring has a downward-sloping guide angle.

[0023] By adopting the above technical solution, when the extrusion block is pushed to move upward, the guide angle on the card block can contact the equipment box and push the card block to squeeze the third spring, thereby enabling the extrusion block to be quickly fixed to the equipment box.

[0024] Optionally, a handle is fixedly installed at the bottom of the extrusion block on one side of the push rod, and the outer surface of the handle is provided with an anti-slip groove.

[0025] By adopting the above technical solution, the anti-slip groove can increase the friction between the worker's hand and the handle, which can reduce the slippage of the worker's hand when gripping the handle.

[0026] In summary, the present invention has the following beneficial effects:

[0027] 1. The conveying device of this invention is assembled from several standard units, making the conveying equipment more compact and simpler, facilitating installation, disassembly, and transportation. It can adapt to different working environments and conditions. Furthermore, the transmission power of the conveying device adopts a distributed arrangement, making its power output more stable and efficient, and enabling the conveying device to achieve longer-distance transportation. Simultaneously, the transported materials are transported through closed pipelines, preventing accidental spillage that could cause personal injury or property damage, thus providing higher safety. In addition, sealed transportation effectively controls dust pollution and irritating odors, resulting in higher environmental friendliness.

[0028] 2. In use, as more and more material enters the feed connector from the hopper, the excess material pushes the gravity plate to move. The gravity plate, through the second connecting rod, pushes the moving block to squeeze the first spring. At this time, the gravity plate moves downward and touches the gravity sensor. The gravity sensor transmits a signal to the controller, which then controls the motor to start. The motor drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate. The second bevel gear drives the threaded rod to rotate, which, with the cooperation of the first slider and the first slide groove, drives the threaded block to move. The threaded block, with the cooperation of the first connecting rod, drives the adjusting plate to rotate, thereby slowing down the material entering the feed connector from the hopper and reducing the possibility of excessive material clogging the feed connector and causing equipment damage.

[0040] Please refer to Figure 1 and Figure 2An automatic conveying device includes a hopper 1, several standard spiral conveying pipes 2, several series joints 3, and a discharge port 4. The series joints 3 include direct connectors and arbitrary angle connectors. Both ends of the series joints 3 are respectively provided with flanges for connecting the standard spiral conveying pipes 2. The standard spiral conveying pipe 2 consists of a main shaft 5, spiral blades 6, seamless steel pipes 7, a front flange 8, an end flange 9, a transmission gear 10, a bearing bracket 11, a hydraulic motor 12, and a reducer 39. The main shaft 5 passes through the seamless steel pipes 7. To better achieve material connection, its front end needs to... Extending a certain distance beyond the seamless steel pipe 7, the end of the spindle 5 is aligned with the seamless steel pipe 7. To avoid eccentric jamming, the spindle 5 needs to be aligned with the seamless steel pipe 7. Specifically, a transmission gear 10 and a bearing bracket 11 are respectively installed at the front and end of the seamless steel pipe 7. The spindle 5 passes through both the transmission gear 10 and the bearing bracket 11 and is fixedly connected to the transmission gear 10. The spiral blade 6 is welded to the spindle 5 along its entire length. Its outer diameter should be slightly smaller than the inner diameter of the seamless steel pipe 7, and its blade pitch should be 1 / 3 to 1 / 2 of the diameter of the seamless steel pipe 7. Its function is to drive the rotation... The material is pushed from the front end to the rear end by a drive mechanism. The minimum diameter of the seamless steel pipe 7 needs to be determined based on the maximum particle size of the material being transported, and its minimum diameter is preferably 15 to 20 times the maximum particle size of the material being transported. The transmission gear 10 is located near the front end of the seamless steel pipe 7, and is fixedly connected to the main shaft 5 in the middle via spokes. This allows the material to pass smoothly and also fully mixes the material, making it easier to transport. The bearing bracket 11 is fixed to the rear end of the seamless steel pipe 7, and has a roller bearing in the center. To ensure smooth material passage, its shape... The design is spoke-shaped; the hydraulic motor 12 is fixed to the outside of the seamless steel pipe 7 and is connected to the transmission gear 10. Its structural function is to provide power for the rotation of the main shaft 5. The reducer 39 is placed between the transmission gear 10 and the hydraulic motor 12. It is used to adjust the rotation speed of the hydraulic motor 12, control the torque output, and ensure a stable feeding rate. It is also used to coordinate the torque and speed of the hydraulic motor 12 of different standard spiral conveyor pipes 2 to avoid mismatch in the material transport speed in the front and rear spiral conveyor pipes, which would cause excessive pressure in the seamless steel pipe 7 and thus cause mechanical failure.

[0041] Please refer to Figure 3 , Figure 4 and Figure 5A regulating box 13 is fixedly installed at the discharge end of the hopper 1. A feed connector 14 is fixedly installed at the outlet end of the regulating box 13. The feed connector 14 can be connected to the standard spiral conveyor pipe 2 through a flange.

The motor 161 can drive the first bevel gear 162 to rotate, the first bevel gear 162 can drive the second bevel gear 163 to rotate, and the second bevel gear 163 can drive the threaded rod 15 to rotate, thereby improving the stability of the rotation of the threaded rod 15.

[0042] Furthermore, a protective shell 35 is fixedly installed on the outer surface of the regulating box 13, and the motor 161 is disposed inside the protective shell 35. An installation groove is provided inside the protective shell 35, and a heat dissipation mesh 36 is fixedly installed on the inner wall of the installation groove. The protective shell 35 protects the motor 161, reducing contact between external objects and the motor 161. The heat generated by the motor 161 during use can be transferred to the outside through the heat dissipation mesh 36.

[0043] Please refer to Figure 3 and Figure 5 A threaded block 17 is threadedly connected to the outer surface of the threaded rod 15. A first connecting rod 18 is hinged to one side of the threaded rod 15. An adjusting plate 19 is hinged to the end of the first connecting rod 18 away from the threaded rod 15. One side of the adjusting plate 19 is rotatably connected to the inner wall of the adjusting box 13 via a rotating shaft. A first sliding mechanism 20 is provided on the side of the threaded block 17 away from the first connecting rod 18. The first sliding mechanism 20 includes a first slider 201, which is fixedly connected to the threaded block 17. A first groove 202 adapted to the first slider 201 is provided inside the adjusting box 13. The first slider 201 and the first groove 202 can limit the movement range of the threaded block 17 and make the threaded block 17 move more smoothly.

[0044] Please refer to Figure 3 and Figure 6 The bottom of the feed connector 14 is located directly below the regulating box 13 and is fixedly installed with an equipment box 21. A first spring 22 is fixedly installed on the inner side wall of the equipment box 21. A moving block 23 is fixedly installed at one end of the first spring 22. A second connecting rod 24 is hinged to the top of the moving block 23. A gravity plate 25 is hinged to the end of the second connecting rod 24 away from the moving block 23. A gravity sensor 26 is fixedly installed on the inner bottom wall of the equipment box 21. A controller 27 is fixedly installed at the bottom of the equipment box 21. The gravity sensor 26 is electrically connected to the controller 27. The controller 27 is electrically connected to the motor 161.

[0045] Furthermore, a second sliding mechanism 28 is provided on the side of the movable block 23 away from the second connecting rod 24. The second sliding mechanism 28 includes a second slider 281, which is fixedly connected to the movable block 23. The inside of the adjusting box 13 is provided with a second sliding groove 282 that is adapted to the second slider 281. The second slider 281 and the second sliding groove 282 can limit the movement range of the movable block 23 and make the movable block 23 move more smoothly.

[0046] Please refer to Figure 6 , Figure 7 and Figure 8 A second spring 29 is fixedly installed inside the equipment box 21. A pressing block 30 is fixedly installed at one end of the second spring 29, extending through the outside of the equipment box 21. A support rod 31 is fixedly installed on the side of the pressing block 30 near the second spring 29. A third spring 32 is fixedly installed inside the pressing block 30, with a locking block 33 fixedly installed at one end. A slot adapted to the locking block 33 is provided inside the equipment box 21. In use, the operator can press the second spring 29 upward through the pressing block 30 to retract the second spring 29. At the same time, the third spring 32 can push the locking block 33 to fix itself to the slot inside the equipment box 21, thereby fixing the pressing block 30. The support rod 31 on the pressing block 30 can contact and press against the gravity plate 25, preventing the gravity plate 25 from contacting the gravity sensor 26, thus closing the gravity adjustment structure.

[0047] Furthermore, a push rod 34 is fixedly installed on the outer side of the locking block 33, and an elongated sliding hole is opened at the bottom of the pressing block 30. The push rod 34 passes through the outside of the elongated sliding hole, allowing the operator to easily move the locking block 33. A downward-sloping guide angle 37 is provided at the end of the locking block 33 away from the third spring 32. When the pressing block 30 is pushed upward, the guide angle 37 on the locking block 33 can contact the equipment box 21 and push the locking block 33 to compress the third spring 32, thereby quickly fixing the pressing block 30 to the equipment box 21. A handle 38 is fixedly installed at the bottom of the pressing block 30 on one side of the push rod 34. An anti-slip groove is provided on the outer surface of the handle 38. The anti-slip groove increases the friction between the operator's hand and the handle 38, reducing the possibility of slippage when the operator grips the handle 38.

[0048] The implementation principle of this invention is as follows: The transportation device of this invention is assembled from several standard units, making the conveying equipment more miniaturized and simple, facilitating equipment installation, disassembly and transportation, and adaptable to different working environments and conditions. In addition, the transmission power of the transportation device adopts a distributed arrangement, making its power output more stable and efficient, and enabling the transmission device to achieve transportation over longer distances. At the same time, the transported materials are transported through closed pipelines, which can avoid accidental spillage of transported materials, causing personal injury and property damage, and has higher safety. In addition, sealed transportation can effectively control dust pollution and irritating odors, making it more environmentally friendly. During use, as more and more material enters the feed inlet 14 from the hopper 1, the excess material can push the gravity plate 25 to move. The gravity plate 25 can push the moving block 23 to squeeze the first spring 22 through the second connecting rod 24. At this time, the gravity plate 25 moves downward and touches the gravity sensor 26. The gravity sensor 26 can transmit a signal to the controller 27, which can control the motor 161 to start. The motor 161 can drive the first bevel gear 162 to rotate. The first bevel gear 162 can drive the second bevel gear 163 to rotate. The second bevel gear 163 can drive the threaded rod 15 to rotate. The threaded rod 15 can drive the threaded block 17 to move under the cooperation of the first slider 201 and the first slide groove 202. The threaded block 17 can drive the adjusting plate 19 to rotate under the cooperation of the first connecting rod 18, thereby slowing down the material entering the feed inlet 14 from the hopper 1 and reducing the situation where excessive material blocks the feed inlet 14 and causes equipment damage.

[0049] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
