Description

Technical Field

[0001] This invention relates to the field of mine ecological restoration technology, and in particular to a double-layer long ecological bag filling device. Background Technology

[0002] With the mining and construction of coal mines, large areas of exposed gangue slopes have been formed, which are highly susceptible to geological disasters such as landslides, collapses, and debris flows. The surface layer of gangue slopes lacks soil for normal plant growth and development, and the water and nutrients necessary for vegetation growth cannot be supplied normally, resulting in soil erosion and damage to the ecological environment. Ecological restoration substrate materials are needed for repair. Currently, when filling ecological bags, cranes are generally used to lift the ecological bags and lay them on the slope, and then manual shovels are used to fill the ecological bags one by one. This process of filling and sowing is very cumbersome, time-consuming, and labor-intensive, affecting the efficiency of ecological bag laying. Moreover, during manual filling, the filler is easily affected by the slope topography and tends to accumulate in the middle of the ecological bag, resulting in uneven filling. Secondly, when laying ecological bags, they need to be hung on a crane, and the crane's mechanical arm lifts the ecological bags high before laying them on the slope. This method of laying ecological bags by crane is very cumbersome.

[0003] To address the above problems, this invention proposes a double-layer elongated eco-bag filling device. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of the existing technology, which is very cumbersome to lay ecological bags by crane, time-consuming and labor-intensive manual filling, and the filling material is easily affected by the slope terrain and piles up in the middle of the ecological bag, resulting in uneven filling of the ecological bag. Therefore, a double-layer long ecological bag filling equipment is proposed.

An arc-shaped clamping plate is welded to the bottom end of the sliding rod, and the arc-shaped clamping plate is used to clamp the bag opening of the ecological bag to the outer wall of the discharge pipe. A through groove is opened on one side of the discharge pipe.

[0008] Furthermore, the anchoring structure includes two rotating shafts rotatably connected to both sides of the conveying cylinder. The ends of the two rotating shafts that are far apart from each other are welded to the same U-shaped plate. The side of the U-shaped plate away from the frame is provided with multiple circular grooves. A second electromagnet is fixed to the inner wall of one side of the circular groove by bolts. An anchor rod is provided in the circular groove, and the second electromagnet generates a magnetic attraction force on the anchor rod. A second motor is fixed to the top of the trolley by bolts. The output shaft of the second motor rotates through the U-shaped plate and is fixedly connected to one end of one of the rotating shafts.

[0009] Furthermore, the top of the push plate is provided with multiple sliding grooves, and a pin is slidably connected in the sliding groove. A first spring is fixed to the bottom end of the pin, and the bottom end of the first spring is fixedly connected to the bottom inner wall of the sliding groove. A first electromagnet is fixed to the inner wall of the sliding groove by bolts, and the first electromagnet generates a magnetic attraction force on the pin. The bottom of the trolley is provided with multiple slots, and the slots engage with the pin.

[0010] Furthermore, the outer wall of the discharge pipe is provided with multiple annular grooves, and the arc-shaped clamp is provided with multiple rubber strips on the side near the discharge pipe, and the rubber strips cooperate with the annular grooves.

[0011] Furthermore, a storage box is bolted to the top of the conveying cylinder, and the storage box is located below the U-shaped plate.

[0012] Furthermore, the conveying cylinder has a conveying channel for seeds to flow into the discharge pipe, and the two ends of the conveying channel are respectively connected to the through slots opened on the second feed hopper and the discharge pipe.

[0013] Furthermore, the second feed hopper includes a feed chamber, a baffle, and a rotating shaft. The baffle is fixedly connected to the upper center of the feed chamber. A rotary motor is fixedly connected to the upper surface of the baffle. The rotary motor is electrically connected to the first motor.

[0014] Furthermore, one end of the rotating shaft is fixed with a threaded rod by bolts, and the bottom end of the threaded rod extends rotatably to the outside of the conveying cylinder. A nut block is threadedly fitted on the outer wall of the threaded rod, and a cam is rotatably connected to one side of the nut block. The cam is slidably connected to the outer wall of the threaded rod through a groove and a slider. A second pin is welded to one side of the cam at a position off-center. A connecting rod is rotatably fitted on the outer wall of the second pin. Connecting belts are detachably connected to both sides of the connecting rod. The connecting belts are used to drive the ecological bag to vibrate. Beneficial effects

[0015] 1. In this invention, a nut block is threaded onto the outer wall of the threaded rod. A cam is rotatably connected to one side of the nut block and slidably connected to the outer wall of the threaded rod. A connecting rod is rotatably connected to one side of the cam via a second pin. Connecting belts are detachably connected to both sides of the connecting rod. The rotating shaft drives the connecting belt to move up and down reciprocally through the threaded rod and the cam. During the filling process, the ecological bag vibrates, preventing the soil in the ecological bag from accumulating in the middle of the ecological bag due to the influence of the protruding parts of the slope. As the connecting belt continuously vibrates the ecological bag, the soil in the ecological bag can be evenly filled into the ecological bag by the action of the slope.

[0016] Second, in this invention, one end of the trapezoidal rod is welded with an L-shaped push rod, one end of the L-shaped push rod slides through the h-shaped plate and is welded with a ring, and the bottom inner wall of the conveying cylinder slides through an inclined rod, which cooperates with the trapezoidal rod; the rotating shaft drives the inclined rod to move down through the turntable and the protrusion, and the cooperation of the trapezoidal rod, the inclined rod and the second spring can drive the L-shaped push rod and the ring to move back and forth. During the process of conveying soil to the ecological bag, the discharge pipe can drive the top of the ecological bag to vibrate back and forth, so as to avoid the soil from accumulating at the opening of the ecological bag.

[0017] Third, in this invention, the conveying cylinder is rotatably connected to the same U-shaped plate via a rotating shaft. One side of the U-shaped plate is provided with multiple circular grooves. A second electromagnet is fixed to the inner wall of one side of the circular groove by bolts. An anchor rod is provided in the circular groove. When the second electromagnet is energized, it generates a magnetic attraction force on the anchor rod, fixing the anchor rod in the circular groove. The U-shaped plate is driven to rotate clockwise by a second motor. The U-shaped plate can anchor the ecological bag on the slope through the anchor rod, preventing the ecological bag from sliding down the slope.

[0018] IV. In this invention, a support frame is welded onto the trolley, and a machine frame is welded to the top of the support frame. A scraper conveyor is installed inside the machine frame, and a first feed hopper for feeding soil is installed at the top of the conveying cylinder. Soil is conveyed into the conveying cylinder through the cooperation of the scraper conveyor and the first feed hopper. The cooperation of the auger and the discharge pipe directly conveys the soil into the ecological bag, eliminating the need for manual filling, reducing the labor intensity of workers, and improving filling efficiency.

[0019] Fifth, in this invention, soil and seeds are automatically conveyed into the ecological bag through the cooperation of the scraper conveyor, the first feed hopper, the second feed hopper, and the discharge pipe, which improves the filling efficiency. In the process of rotating and conveying soil, the rotating shaft and the auger can automatically clamp the ecological bag on the outer wall of the discharge pipe. At the same time, it can also drive the bag mouth and the bag body of the ring and the connecting belt to vibrate, which not only avoids the bag mouth from getting blocked, but also allows the soil in the ecological bag to be evenly filled into the ecological bag by the action of the slope. In addition, the rotation of the U-shaped plate can directly anchor the ecological bag to the slope through the anchor rod, making the filling and laying of soil extremely efficient.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1

[0023] Reference Figures 1-9 A double-layer long ecological bag filling equipment is used in the field of mine ecological restoration. It includes a trolley 1. Preferably, in order to ensure the stability of the trolley 1, multiple adjustable feet (not shown in the figure, and the adjustable feet are commercially available products) can be installed at the bottom of the trolley 1. When the trolley 1 moves to the designated position, the feet are rotated to make the feet touch the ground, which increases the stability of the trolley 1 during use. A bracket 2 is welded on the trolley 1, and a frame 3 is welded to the top of the bracket 2. A scraper conveyor 4 is provided in the frame 3 (the height of the scraper in the figure is only schematic, and the specific height can be set according to actual needs). It also includes a conveying cylinder 5, which is fixed to the top of the trolley 1 by bolts. The top of the conveying cylinder 5 is provided with a first feed hopper 6 for conveying soil, and one end of the scraper conveyor 4 is located above the first feed hopper 6. The scraper conveyor 4 is used to convey soil into the conveying cylinder 5.

[0024] Reference Figures 2-5 The equipment also includes a shaking structure at the bottom of the trolley 1, used to shake the opening of the ecological bags to prevent soil from accumulating at the bag opening. The shaking structure includes a trapezoidal rod 9 slidably connected to the bottom of the trolley 1. One end of the trapezoidal rod 9 is welded with an L-shaped push rod 10, and the top of the L-shaped push rod 10 is slidably connected to the bottom of the trolley 1. An H-shaped plate 11 is welded to the bottom of the trolley 1. The end of the L-shaped push rod 10 away from the trapezoidal rod 9 slides through the H-shaped plate 11 and is welded with a ring 12. The ring 12 is used to shake the ecological bags. A rotating shaft 13 is rotatably connected inside the conveying cylinder 5. An auger 14 for conveying soil into the discharge pipe 8 is fixed to the outer wall of the rotating shaft 13. A turntable 15 is fixedly sleeved on the outer wall of the rotating shaft 13. Multiple protrusions 16 are welded to the outer wall of the turntable 15. An inclined rod 17 slides through the bottom inner wall of the conveying cylinder 5. Rod 17 cooperates with trapezoidal rod 9, and the top of L-shaped push rod 10 cooperates with protrusion 16. One end of conveying cylinder 5 is fixed with first motor 18 through placement plate. The output shaft of first motor 18 is fixedly connected to one end of rotating shaft 13 through coupling. A second spring 19 is fixed on the side of L-shaped push rod 10 away from trapezoidal rod 9, and the other end of second spring 19 is fixedly connected to one side of h-shaped plate 11. First motor 18 drives rotating shaft 13 and auger 14 to rotate. Auger 14 conveys soil through discharge pipe 8 into ecological bag. In addition, as rotating shaft 13 continues to rotate, the cooperation of trapezoidal rod 9 and second spring 19 can drive L-shaped push rod 10 and ring 12 to move back and forth. During the process of conveying filler to ecological bag, discharge pipe 8 can drive the top of ecological bag to vibrate back and forth, avoiding soil accumulation at the opening of ecological bag.

[0025] Reference Figures 2-6The device also includes a clamping structure at the bottom of the trolley 1, used to automatically fit the ecological bag onto the outer wall of the discharge pipe 8, preventing the ecological bag from detaching from the discharge pipe 8 during the filling process. The clamping structure includes a push plate 20 slidably connected to the bottom of the trolley 1. The push plate 20 and the H-shaped plate 11 are elastically connected by multiple tension springs 21. A push rod 22 is welded to the side of the L-shaped push rod 10 away from the trapezoidal rod 9, and one end of the push rod 22 slides through the H-shaped plate 11 and contacts one side of the push plate 20. A rotating disk 23 is rotatably fitted onto the outer wall of the discharge pipe 8. A first pin 24 is welded to the top of the rotating disk 23 off-center. A connecting rod 25 is slidably connected to the side of the push plate 20 near the discharge pipe 8, and one end of the rotating disk 23 is rotatably connected to the first pin 24. Multiple arc-shaped holes 26 are opened on the rotating disk 23, and sliding rods 2 are slidably connected in the arc-shaped holes 26. 7. The bottom of the trolley 1 is provided with multiple guide grooves 28, and the top of the sliding rod 27 extends into the guide groove 28 and slides in cooperation with the guide groove 28. The bottom end of the sliding rod 27 is welded with an arc-shaped clamping plate 29, and the arc-shaped clamping plate 29 is used to clamp the opening of the ecological bag on the outer wall of the discharge pipe 8. A through groove 60 is opened on one side of the discharge pipe 8. The opening of the ecological bag is manually put onto the discharge pipe 8. The rotating shaft 13 drives the turntable 15 and the protrusion 16 to rotate. The protrusion 16 pushes the inclined rod 17 down. The inclined rod 17 cooperates with the trapezoidal rod 9 to push the L-shaped push rod 10, the push rod 22 and the push plate 20 to the right. The push plate 20 pushes the rotating disk 23 to rotate through the connecting rod 25. During the rotation of the rotating disk 23, the arc-shaped clamping plate 29 moves to the middle through the cooperation of the sliding rod 27 with the arc-shaped hole 26 and the guide groove 28. The opening of the ecological bag is clamped by multiple arc-shaped clamping plates 29.

[0026] Reference Figures 6-8The top of the push plate 20 is provided with multiple sliding grooves 36, and a pin 37 is slidably connected in the sliding groove 36. A first spring 38 is fixed to the bottom end of the pin 37, and the bottom end of the first spring 38 is fixedly connected to the bottom inner wall of the sliding groove 36. A first electromagnet 39 is fixed to the inner wall of the sliding groove 36 by bolts, and the first electromagnet 39 generates a magnetic attraction force on the pin 37. The bottom of the trolley 1 is provided with multiple slots 40, and the slots 40 engage with the pin 37. The inclined rod 17 and the trapezoidal rod 9 cooperate to push the L-shaped push rod 10, the push rod 22 and the push plate 20 to the right. Multiple arc-shaped clamps 29 clamp the opening of the ecological bag. At this time, the pin 37... 7. Under the elastic force of the first spring 38, the push plate 20 is inserted into the slot 40 to position the push plate 20, ensuring that the arc-shaped clamp 29 can continuously clamp the opening of the ecological bag. Then, the ecological bag is laid on the slope. When the first electromagnet 39 is energized, the magnetic attraction force generated by the first electromagnet 39 on the pin 37 is greater than the elastic force of the first spring 38. The pin 37 retracts from the slot 40 into the slide groove 36. At this time, the push plate 20 is reset under the pulling force of the tension spring 21, the rotating disk 23 rotates in the opposite direction, and the arc-shaped clamp 29 releases the clamp on the opening of the ecological bag. Then, the trolley 1 is moved to the next position, and the filling and laying of the ecological bag are carried out again.

[0028] Reference Figure 3 and Figure 9 The equipment also includes anchoring structures on both sides of the conveying cylinder 5 to automatically fix the filled ecological bags on the slope. The anchoring structures include two rotating shafts 30 rotatably connected to both sides of the conveying cylinder 5. The ends of the two rotating shafts 30 that are far apart from each other are welded with the same U-shaped plate 31 (the height of the U-shaped plate 31 can be set according to actual needs; the attached drawings of this application are only schematic). The top of the trolley 1 is provided with a through groove that matches the U-shaped plate 31. The side of the U-shaped plate 31 away from the frame 3 is provided with multiple circular grooves 32.

An anchor rod 34 is provided in the circular groove 32, and the second electromagnet 33 generates a magnetic attraction force on the anchor rod 34. A second motor 35 is fixed to the top of the trolley 1 by bolts. The output shaft of the second motor 35 rotates through the U-shaped plate 31 and is fixedly connected to one end of one of the rotating shafts 30. When the second electromagnet 33 is energized, it generates a magnetic attraction force on the anchor rod 34, fixing the anchor rod 34 in the circular groove 32. The second motor 35 drives the U-shaped plate 31 to rotate clockwise, and the U-shaped plate 31 can anchor the ecological bag on the slope through the anchor rod 34.

[0029] Reference Figure 9 The top of the conveying cylinder 5 is fixed with a storage box 43 by bolts, and the storage box 43 is located below the U-shaped plate 31.

[0030] Reference Figure 8 and Figure 9 Both the pin 37 and the anchor rod 34 are made of iron. The second electromagnet 33 and the first electromagnet 39 can generate magnetic attraction forces on the anchor rod 34 and the pin 37 respectively, thereby fixing the anchor rod 34 and releasing the brake of the push plate 20. Example 2

[0031] Reference Figure 3 , Figure 4 and Figure 12 Improvements based on Embodiment 1: The conveying cylinder 5 has a conveying channel 44 for seeds to flow into the discharge pipe 8. The two ends of the conveying channel 44 are connected to the through slots 60 opened on the second feed hopper 7 and the discharge pipe 8, respectively. The second feed hopper 7 includes a feed chamber 45, a baffle 46, and a rotating shaft 47. The baffle 46 is fixedly connected to the upper center position of the feed chamber 45. A rotary motor 48 is fixedly connected to the upper surface of the baffle 46. The rotary motor 48 is electrically connected to the first motor 18. One end of the rotating shaft 47 passes through the baffle 46 and is rotatably connected to the rotary motor 48. The other end is fixedly connected to a spiral conveying rod 49. The lower end of the spiral conveying rod 49... The end is flush with the lower surface of the rotating shaft 47. A dividing plate 50 is fixedly connected to the inner cavity of the discharge pipe 8. A protective cover 51 is fixedly connected to the discharge pipe 8. The inner cavity formed by the protective cover 51 and the inner wall of the discharge pipe 8 is connected to the through groove 60. During operation, the seeds are fed into the feeding cavity 45. The rotating shaft 47 is driven to rotate by the rotating motor 48. The rotating shaft 47 drives the screw conveyor 49 to rotate, thereby conveying the seeds to the conveying channel 44. The seeds flow into the discharge pipe 8 through the conveying channel 44. The seeding rate is controlled by controlling the rotation speed of the rotating motor 48. The protective cover 51 can prevent soil from clogging the through groove 60 set on the discharge pipe 8. Example 3

[0032] refer to Figure 10 and Figure 11Improvements based on Example 1: One end of the rotating shaft 13 is fixed with a threaded rod 52 by bolts, and the bottom end of the threaded rod 52 extends rotatably to the outside of the conveying cylinder 5. A nut block 53 is threadedly fitted on the outer wall of the threaded rod 52. A cam 54 is rotatably connected to one side of the nut block 53, and the cam 54 is slidably connected to the slider through a groove on the outer wall of the threaded rod 52. A second pin 55 is welded to one side of the cam 54 at a position off-center. A connecting rod 56 is rotatably fitted on the outer wall of the second pin 55. Connecting belts 57 are detachably connected to both sides of the connecting rod 56. The connecting belts 57 are used to drive the ecological bag to vibrate. The bottom end of the ecological bag passes through the connecting belts 57. The rotating shaft 13 drives the cam 54 to rotate through the threaded rod 52. The cam 54 drives the connecting belts 57 to move up and down reciprocally through the connecting rods 56. Therefore, during the filling process, the ecological bag can also be driven to vibrate, avoiding the soil in the ecological bag from accumulating in the middle of the ecological bag due to the influence of the protruding part of the slope. As the connecting belts 57 continuously vibrate the ecological bag, the soil in the ecological bag can be evenly filled into the ecological bag by the action of the slope. Example 4

[0033] refer to Figure 13 Improvements based on Example 2: The ecological bag includes a bag body 58 and a biodegradable diaphragm 59. The two sides of the diaphragm 59 are sewn to the inner surface of the bag body 58. After one end of the bag body 58 is fitted onto the discharge pipe 8, the diaphragm 59 abuts against the dividing plate 50. When the soil flows through the discharge pipe 8, the dividing plate 50 causes the soil to flow into two channels separated by the diaphragm 59. The seeds are released into the outer channel, allowing the seeds to germinate better and preventing them from falling into the deep soil layer and affecting their germination. The diaphragm 59 sewn to the two sides of the inner surface of the bag body 58 is made of polylactic acid polymer, which has good toughness and can degrade when it comes into contact with water. When the ecological bag is irrigated after filling, the diaphragm 59 will slowly degrade, allowing the roots of the seeds to penetrate deeper.

[0034] A method for using a double-layer elongated eco-bag filling device includes the following steps: S1. Move the trolley 1 to the top of the slope, then pass the opening of the ecological bag through the ring 12 and put it on the discharge pipe 8. The first motor 18 drives the turntable 15 and the protrusion 16 to rotate through the rotating shaft 13. The protrusion 16 pushes the inclined rod 17 down. The inclined rod 17 cooperates with the trapezoidal rod 9 to push the L-shaped push rod 10, the push rod 22 and the push plate 20 to the right. The push plate 20 pushes the rotating disk 23 to rotate through the connecting rod 25. During the rotation of the rotating disk 23, the sliding rod 27 cooperates with the arc hole 26 and the guide groove 28 to drive the arc clamp 29 to move to the middle. The opening of the ecological bag is clamped by multiple arc clamps 29. At this time, the pin 37 is inserted into the slot 40 under the elastic force of the first spring 38 to position the push plate 20 and ensure that the arc clamp 29 can continuously clamp the opening of the ecological bag. Then, the ecological bag is laid on the slope. S2. Soil is conveyed onto the scraper conveyor 4 by an excavator or loader. The scraper conveyor 4 conveys the soil into the conveying cylinder 5. The first motor 18 drives the rotating shaft 13 and the auger 14 to rotate. The auger 14 conveys the soil through the discharge pipe 8 into the ecological bag. The first motor 18 also drives the rotating shaft 47 and the spiral conveying rod 49 to rotate and convey the seeds into the conveying channel 44. The seeds flow into the discharge pipe 8 through the conveying channel 44 and are conveyed into the ecological bag. In addition, as the rotating shaft 13 continues to rotate, the trapezoidal rod 9 and the second spring 19 work together to drive the L-shaped push rod 10 and the ring 12 to move back and forth. During the process of conveying soil into the ecological bag, the discharge pipe 8 can drive the top of the ecological bag to vibrate back and forth to prevent the soil from accumulating at the opening of the ecological bag. S3. When laying the ecological bag, the bottom end of the ecological bag passes through the connecting belt 57. The rotating shaft 13 drives the cam 54 to rotate through the threaded rod 52. The cam 54 drives the connecting belt 57 to move up and down repeatedly through the connecting rod 56. Therefore, the ecological bag can also be vibrated during the filling process to prevent the soil in the ecological bag from being affected by the protruding part of the slope and accumulating in the middle of the ecological bag. As the connecting belt 57 continuously vibrates the ecological bag, the soil in the ecological bag can be evenly filled in the ecological bag by the slope. The threaded rod 52 can also prevent the seeds from being blocked in the conveying channel 44 during the rotation process. S4. When the eco-bag is filled, take out the anchor rod 34 from the storage box 43 and insert it into the circular groove 32. The second electromagnet 33 is energized to generate a magnetic attraction force on the anchor rod 34, fixing the anchor rod 34 in the circular groove 32. Then rotate the nut block 53, which is threadedly connected to the threaded rod 52. The nut block 53 drives the cam 54 and the connecting rod 56 to move towards the conveying cylinder 5, so as to prevent the cam 54 and the connecting rod 56 from obstructing the rotation of the U-shaped plate 31. Then, the second motor 35 drives the U-shaped plate 31 to rotate clockwise. The U-shaped plate 31 can anchor the eco-bag on the slope through the anchor rod 34. The second electromagnet 33 is de-energized, and the U-shaped plate 31 rotates in the opposite direction to reset. Then, remove the connecting strap 57 from the connecting rod 56 and pull the connecting strap 57 out from under the eco-bag for later use. S5. Next, the first electromagnet 39 is energized. The magnetic attraction force generated by the first electromagnet 39 on the pin 37 is greater than the elastic force of the first spring 38. The pin 37 retracts from the slot 40 into the slide groove 36. At this time, the push plate 20 is reset under the pulling force of the tension spring 21, the rotating disk 23 rotates in the opposite direction, and the arc-shaped clamp 29 releases the clamp on the opening of the ecological bag. Then, the trolley 1 is moved to the next position, and the filling and laying of the ecological bag are carried out again.
