Description

Technical Field

[0001] This invention relates to the field of material feeding and guiding technology, specifically to an adjustable material feeding and guiding device for commercial concrete. Background Technology

[0002] Ready-mixed concrete feeding refers to the entire process of transporting and accurately measuring raw materials such as sand, gravel, cement, fly ash, water, and admixtures from the storage site and then feeding them into the mixer. It is the core link in the production of the mixing plant and directly affects efficiency and quality. During the feeding process of ready-mixed concrete, it is necessary to use guiding devices to keep the concrete centered, prevent it from deviating, prevent large stones from rolling off, and prevent mortar separation. In the existing technology, during the feeding of ready-mixed concrete, the material is usually guided by a guide chute and a baffle plate. However, when the guide angle needs to be adjusted, the fixing bolts of the guide chute need to be loosened, the tilt angle adjusted, and then fixed. This makes it inconvenient to automatically adjust the guide angle according to the feeding speed, which reduces the feeding efficiency of the ready-mixed concrete raw materials.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-7 As shown, this embodiment proposes an adjustable feeding guide device for commercial concrete, including a feeding platform 1. A feeding cylinder 2 and a feeding cylinder 3 are installed obliquely on the upper side of the feeding platform 1. An adjusting guide component is provided between the feeding cylinder 2 and the feeding cylinder 3 and the feeding platform 1. A feeding conveyor belt 4 is driven inside the feeding cylinder 2. A feeding hopper 48 is connected through the feeding cylinder 2. The feeding hopper 48 is located between two adjacent baffles 12 and is located above the feeding conveyor belt 4, which facilitates the stable delivery of commercial concrete raw materials to the feeding conveyor belt 4. A feeding transmission belt 5 is driven inside the feeding cylinder 3. A guide transmission belt 6 is driven between the feeding conveyor belt 4 and the feeding transmission belt 5. Two anti-deviation limit plates 7 are rotatably installed on the upper side of the feeding conveyor belt 4 through an automatic anti-deviation component. Multiple anti-separation rollers 8 are rotatably installed on the upper side of the feeding transmission belt 5. The adjusting guide assembly includes a bracket 9, which is fixedly connected to the top of the feeding platform 1. A rotating support plate 10 is rotatably connected to the bracket 9. The rotating support plate 10 is fixedly connected to the bottom of one side of the feeding cylinder 2, which increases the stability of the feeding cylinder 2 and the feeding cylinder 3 rotating on the feeding platform 1. A pushing assembly is provided at the bottom of the other side of the feeding cylinder 2.

[0020] refer to Figure 1, Figure 2 as well as Figure 3 Multiple support plates 11 are fixedly connected to the inner bottom wall of the feeding cylinder 2 and the inner bottom wall of the feeding cylinder 3. Multiple baffles 12 are fixedly connected between the multiple support plates 11. Multiple pillars are fixedly connected between the multiple baffles 12 and the inner side wall of the feeding cylinder 3 and the inner side wall of the feeding cylinder 2, respectively, which increases the stability of the baffles 12 in the feeding cylinder 3 and the feeding cylinder 2. The feeding conveyor belt 4 and the feeding transmission belt 5 are located between the multiple baffles 12. Multiple drive rods 13 are rotatably connected through the multiple baffles 12. Drive rollers are fixedly connected to the multiple drive rods 13. The feeding conveyor belt 4 and the feeding transmission belt 5 are respectively driven and installed between the multiple drive rollers. Drive motors 14 are installed on the outer side wall of the feeding cylinder 2 and the outer side wall of the feeding cylinder 3. Two drive motors 14 are fixedly connected to two adjacent drive rods 13 respectively. Starting the two drive motors 14 respectively can cause the multiple drive rods 13 to drive the multiple drive rollers to rotate, so that the multiple drive rollers can drive the feeding conveyor belt 4 and the loading transmission belt 5 to rotate, thereby enabling the stable and continuous conveying of commercial concrete raw materials.

[0021] refer to Figure 3 as well as Figure 5 The automatic anti-deviation component includes a fixed frame 15. Each of the two adjacent baffles 12 has a fixing groove that matches the fixed frame 15, allowing the fixed frame 15 to be quickly installed and removed between the two baffles 12. An adjusting electric cylinder 16 is installed at the top of the fixed frame 15. An adjusting plate 17 is fixedly connected to the output end of the adjusting electric cylinder 16. Two adjusting rods 18 are symmetrically connected to the adjusting plate 17, and both adjusting rods 18 are connected through the fixed frame 15. An anti-deviation frame 19 is fixedly connected between the two adjusting rods 18. A position sensor 20 is installed on the anti-deviation frame 19. The position sensor 20 is electrically connected to the adjusting rod and can monitor and sense the conveying position of the commercial concrete raw materials on the feeding conveyor belt 4. Two anti-deviation limit plates 7 are symmetrically rotated on the anti-deviation frame 19 through two anti-deviation axes. Anti-deviation strips 21 are detachably connected to two baffles 12 on both sides of the feeding conveyor belt 4. Two anti-deviation screws 47 are threaded between the anti-deviation strip 21 and the adjacent baffle 12, facilitating quick installation and removal of the anti-deviation strip 21 on the baffle 12. Multiple anti-deviation cylinders 22 are arrayed on each of the two anti-deviation strips 21. Anti-deviation rods 23 are slidably connected through each anti-deviation cylinder 22. An anti-deviation spring 24 is fixedly connected between each anti-deviation rod 23 and the inner wall of the adjacent anti-deviation cylinder 22. A buffer strip is connected through the anti-deviation rod 23. A buffer strip is provided on the inner wall of each anti-deviation cylinder 22 for the buffer strip to... The sliding buffer groove can buffer the rebound of the anti-deviation spring 24 when the buffer strip slides in the buffer groove. Multiple anti-deviation rods 23 are rotatably connected to multiple anti-deviation blocks 25. Two positioning plates 26 are fixedly connected to each of the multiple anti-deviation blocks 25. The two positioning plates 26 are detachably connected to two anti-deviation limit plates 7. The anti-deviation limit plates 7 are provided with positioning grooves that match the positioning plates 26. Two positioning screws are threaded between the positioning plates 26 and the anti-deviation limit plates 7. By turning the positioning screws between the anti-deviation limit plates 7 and the positioning plates 26, the anti-deviation limit plates 7 and the positioning plates 26 can be quickly connected and disassembled. When the position sensor 20 detects that the conveying position of the commercial concrete raw material on the feeding conveyor belt 4 deviates from the set value, it sends an electrical signal to start the adjusting cylinder 16. The adjusting cylinder 16 drives the adjusting plate 17 to move, so that the adjusting plate 17 drives the two adjusting rods 18 to move. Thus, the anti-deviation frame 19 can drive the two anti-deviation limit plates 7 to move to a certain extent. At the same time, during the movement of the anti-deviation limit plates 7, multiple anti-deviation cylinders 22, multiple anti-deviation rods 23, and multiple anti-deviation springs 24 will limit the movement of the anti-deviation limit plates 7, so that they rotate on the anti-deviation rods 23. By adjusting the rotation angle between the two anti-deviation limit plates 7, the anti-deviation correction range between the two anti-deviation limit plates 7 can be adjusted, so that the commercial concrete raw material is centered throughout the conveying process on the feeding conveyor belt 4, preventing deviation and ensuring stable material flow.

[0022] refer to Figure 2 , Figure 4 as well as Figure 7 A feeding speed sensor 27 is installed on the inner top wall of the feeding cylinder 3, which can monitor and sense the conveying speed of the commercial concrete raw materials on the feeding conveyor belt 5. The feeding speed sensor 27 is electrically connected to the lifting cylinder 28, and the lifting cylinder 28 is installed at the top of the feeding cylinder 3. The output end of the lifting cylinder 28 passes through the side wall of the feeding cylinder 3 and is fixedly connected to the lifting frame 29. The bottom end of the lifting frame 29 is connected to multiple buffer rods 30 in a rectangular array. Each of the multiple buffer rods 30 is fitted with a buffer cylinder 31. Two driven plates 32 are fixedly connected between the multiple buffer cylinders 31. Multiple driven rods are rotatably connected between the two driven plates 32. Multiple anti-separation rollers 8 are fixedly connected to the multiple driven rods respectively. A buffer spring 34 is fixedly connected to the inner wall of a plurality of buffer cylinders 31. The plurality of buffer springs 34 are fixedly connected to a plurality of buffer rods 30 respectively, and a buffer slide plate 35 is connected through each buffer rod 30. A buffer groove is provided on the inner wall of the buffer cylinder 31 for the buffer slide plate 35 to slide. When the buffer slide plate 35 slides in the buffer groove, it can buffer the rebound of the buffer spring 34. Multiple buffer cylinders 31, multiple buffer rods 30, and multiple buffer springs 34 elastically connect the lifting frame 29 and the two driven plates 32. When the feeding speed sensor 27 detects that the conveying speed of the goods on the feeding conveyor belt 5 exceeds the set value and some large stones fall down, the feeding speed sensor 27 sends an electrical signal to start the lifting cylinder 28. This causes the lifting frame 29, multiple buffer cylinders 31, multiple buffer rods 30, two driven plates 32, and multiple driven rods to move multiple anti-separation rollers 8 downward, thus blocking the raw concrete material on the feeding conveyor belt 5. At the same time, during the conveying process of the feeding conveyor belt 5, the multiple anti-separation rollers 8 will come into contact with larger stones and move upward, causing the multiple buffer rods 30 to move within the multiple buffer cylinders 31 respectively. This adjusts the height of the multiple anti-separation rollers 8, thereby stabilizing and preventing separation of the raw concrete material on the feeding conveyor belt 5.

[0023] refer to Figure 2 as well as Figure 6 Both the feeding cylinder 2 and the loading cylinder 3 are equipped with tensioning components. The tensioning components include a tensioning motor 36, which is installed on the outer side wall of the loading cylinder 3. The output end of the tensioning motor 36 passes through the side wall of the loading cylinder 3 and is fixedly connected to a tensioning rotating rod 37. The tensioning motor 36 can drive the tensioning rotating rod 37 to perform forward and reverse rotation at a certain angle. A tensioning frame 38 is fixedly connected to the tensioning rotating rod 37, and a tensioning roller 39 is rotatably connected to the tensioning rotating frame 38. Two anti-shift plates 40 are symmetrically connected to the tensioning rotating rod 37. Both anti-shift plates 40 are provided with anti-shift grooves for the tensioning roller 39 to rotate. When the tensioning roller 39 rotates on the tensioning rotating frame 38, the tensioning roller 39 will also rotate in the corresponding anti-shift grooves on the two anti-shift plates 40, which limits the movement of the tensioning roller 39 and increases the stability of the rotation of the tensioning roller 39. When the tensioning motor 36 is started, the tensioning rod 37 drives the tensioning frame 38 to rotate. At the same time, the tensioning frame 38 drives the tensioning roller 39 to rotate to a certain extent. The angle of the tensioning roller 39 can be adjusted. When the tensioning roller 39 contacts the bottom of the feeding conveyor belt 4 or the loading transmission belt 5, the feeding conveyor belt 4 or the loading transmission belt 5 can be tensioned to a certain extent.

[0024] refer to Figure 1The pushing component includes a mounting base 41, which is detachably mounted on the top of the feeding platform 1. Two pushing electric cylinders 42 are symmetrically mounted on the mounting base 41. A pushing frame 43 is fixedly connected to the bottom end of the feeding cylinder 2. A pushing rod 44 is fixedly connected to the pushing frame 43. The output ends of the two pushing electric cylinders 42 are rotatably connected to the pushing rod 44. Two mounting blocks are symmetrically connected to each of the two mounting bases 41. The feeding platform 1 has a mounting groove that matches the mounting blocks, which increases the stability of the mounting blocks when placed on the feeding platform 1. Each mounting block is threadedly connected to the feeding platform 1 with a mounting screw, which allows for quick installation and removal of the mounting blocks and pushing electric cylinders 42 on the feeding platform 1. When both push cylinders 42 are activated simultaneously, the push rod 44 and the push frame 43 push one side of the feeding cylinder 2, allowing the other side of the feeding cylinder 2 to rotate on the support 9 via the rotating support plate 10. This allows the angle of use of the feeding cylinder 2 and the feeding conveyor belt 4 to be adjusted according to actual needs. Furthermore, when the two push cylinders 42 located at the loading cylinder 3 are activated, the loading cylinder 3 can also be rotated at a certain angle through the cooperation of the push frame 43, the push rod 44, the rotating support plate 10, and the support 9, thereby allowing the angle of use of the loading conveyor belt 5 to be adjusted.

[0025] refer to Figure 1 as well as Figure 2 Multiple connecting plates are fixedly connected to the feeding platform 1. Two connecting frames 45 are fixedly connected between the multiple connecting plates. Two driving rods are rotatably connected between the two connecting frames 45. Driving rollers are fixedly connected to each of the two driving rods. The guide transmission belt 6 is installed between the two driving rollers. A driving motor 46 is installed on one of the connecting frames 45. The output end of the driving motor 46 is fixedly connected to the adjacent driving rod. Multiple connecting plates can stably support the two connecting frames 45, so as to stably support the two driving rods, two driving rollers and guide transmission belt 6, start the driving motor 46, and enable the two driving rods and two driving rollers to drive the guide transmission belt 6 to transmit power, thereby enabling the guide transmission belt 6 to stably guide and transport the commercial concrete raw materials.

[0026] In this embodiment, when the raw material of commercial concrete enters the feeding cylinder 2 through the feeding hopper 48, the two drive motors 14 are started simultaneously, causing multiple drive rods 13 and multiple drive rollers to rotate and drive the feeding conveyor belt 4 and the feeding transmission belt 5 respectively. At the same time, the drive motor 46 is started, causing the two drive rods and two drive rollers to drive the guide transmission belt 6. Thus, the raw material of commercial concrete can be stably guided and transported through the feeding conveyor belt 4, the guide transmission belt 6 and the feeding transmission belt 5. During the continuous conveying of raw materials for commercial concrete, when it is necessary to adjust the guiding angle according to the actual material conveying speed, multiple push cylinders 42 can be activated to push one side of the feeding cylinder 2 and one side of the feeding cylinder 3 respectively, so that the feeding cylinder 2 and the feeding cylinder 3 can rotate at a certain angle on the two supports 9 respectively. By adjusting the angle of the feeding cylinder 2 and the feeding cylinder 3, the inclination angle of the feeding conveyor belt 4 and the feeding transmission belt 5 can be adjusted, thereby adjusting the material conveying speed. When the position sensor 20 detects that the conveying position of the commercial concrete raw material on the feeding conveyor belt 4 deviates from the set value, it will send an electrical signal to start the adjusting electric cylinder 16, so that the adjusting plate 17 and the two adjusting rods 18 drive the anti-deviation frame 19 to move. This allows the two anti-deviation limit plates 7 to rotate on the anti-deviation frame 19. By adjusting the anti-deviation range between the two anti-deviation limit plates 7, the commercial concrete raw material can be kept in a centered conveying state on the feeding conveyor belt 4. When the feeding speed sensor 27 detects that the conveying speed of the goods on the feeding conveyor belt 5 exceeds the set value and some large stones fall down, the feeding speed sensor 27 sends an electrical signal to start the lifting cylinder 28, which causes the lifting frame 29, multiple buffer cylinders 31, multiple buffer rods 30, two driven plates 32 and multiple driven rods 33 to drive multiple anti-separation rollers 8 to move down, which provides a certain degree of obstruction to the commercial concrete raw materials on the feeding conveyor belt 5, thereby improving the stability of the centralized conveying of commercial concrete raw materials.
