Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of compaction devices, and in particular to a compaction device for dam filling. Background Technology
[0002] When constructing a dam, compaction is required around the dam, necessitating the use of compaction devices. Existing technologies disclose various dam filling compaction devices, including a pressure roller with rotating shafts at both ends connected to a support. One end of the support has a connecting lug for connection to a tractor. A main rotating wheel is fitted onto one end of the pressure roller, outside the rotating shaft. A crushing box is installed within the support, on one side of the pressure roller. Inside the crushing box is a crushing roller, one end of which passes through the support. A driven rotating wheel is fitted between the support and the crushing box, outside the crushing roller, and is connected to the main rotating wheel via a transmission belt. A scraper is installed above the crushing box. This invention uses the scraper to remove impurities adhering to the surface of the pressure roller, and then the crushing roller breaks up the clumps of impurities, dispersing them back onto the underlying soil layer for further compaction by subsequent pressure rollers.
[0003] In practice, the reason why soil adheres to the pressure roller is that the soil has too high a moisture content. The existing compaction device does not re-mix the soil after scraping it off and breaking it up to reduce the moisture content. This causes the scraped and broken soil to re-adhere to the pressure roller, resulting in the soil not being able to fully bond with the ground. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a dam filling compaction device that reduces the moisture content of the soil by mixing dry soil and mud, thereby reducing soil re-adhesion and improving the compaction effect.
[0005] This utility model discloses a dam filling and compaction device, including a frame and a pressure roller, with the pressure roller rotatably mounted at the rear of the frame; it also includes lugs, a scraper, a collection trough, a crushing mechanism, a dry soil box, and a soil outlet. Lugs are installed at the front of the frame, and the scraper is mounted on the frame via a bracket. The rear edge of the scraper scrapes the upper front surface of the pressure roller. The collection trough is installed in the middle of the frame, and the crushing mechanism is installed inside the collection trough. The collection trough is located below the front edge of the scraper, and a mud discharge port is provided at the bottom of the collection trough. The dry soil box is mounted on the frame, located in front of the collection trough. The dry soil box has a chamber for storing dry soil inside, and a soil outlet is provided at the lower end of the side wall of the dry soil box, located above the collection trough. The lugs are connected to a tractor or... Other vehicles connect, thus moving the frame. The frame drives the pressure rollers to roll and compact the area around the dam. During compaction, scrapers scrape off the soil adhering to the outer surface of the pressure rollers and guide it into the collection trough. Dry soil from the dry soil box is fed into the collection trough through the soil outlet. The crushing mechanism mixes the scraped-off soil and dry soil in the collection trough, thereby blending the soil and reducing its moisture content. The blended soil is then scattered onto the ground in front of the pressure rollers through the mud discharge port at the bottom of the collection trough and is compacted again by the pressure rollers. Because the soil moisture content is reduced, the chance of soil adhering to the surface of the pressure rollers is reduced, and the scraped and broken soil is better bonded to the ground, improving the compaction effect.
[0006] Preferably, the crushing mechanism includes a shaft, multiple stirring rods, and a transmission assembly. The shaft is rotatably mounted in the collection trough, and multiple stirring rods are evenly mounted on the shaft, located inside the collection trough. The shaft is connected to the pressure roller via the transmission assembly. The transmission assembly can be a chain drive assembly, belt drive assembly, etc. When the frame drags the pressure roller to roll and compact the ground, the pressure roller drives the shaft to rotate through the transmission assembly. The shaft drives the multiple stirring rods to rotate, breaking up the soil scraped off by the scraper in the collection trough and mixing and blending the soil and dry soil. The structure is simple and practical.
[0007] Preferably, the assembly also includes a second shaft, multiple second stirring rods, and two gears. The second shaft is rotatably mounted in the collection trough and is located in front of the first shaft. Multiple second stirring rods are mounted on the second shaft and are located in the collection trough. The multiple second stirring rods are arranged alternately with the multiple first stirring rods. The two gears are concentrically mounted at the ends of the first and second shafts, respectively, and the two gears mesh. When the pressure roller drives the first shaft to rotate through the transmission assembly, the two gears mesh, thereby driving the second shaft to rotate through the meshing of the two gears. The second shaft drives the multiple second stirring rods to rotate, so that the multiple first stirring rods and the multiple second stirring rods can disperse, mix, and blend the soil and dry soil, thereby improving the mixing efficiency.
[0008] Preferably, it also includes a guide channel, the front end of which is hinged to the soil outlet and connected to the soil outlet. The rear end of the guide channel rests on multiple mixing rods 2. The dry soil inside the dry soil box is transported to the collection tank through the soil outlet and the guide channel. When the shaft 2 drives the multiple mixing rods 2 to rotate, the multiple mixing rods 2 cause the rear end of the guide channel to swing up and down, so that the dry soil transported on the guide channel is evenly distributed into the collection tank, thereby improving the efficiency of mixing and blending soil and dry soil.
[0009] Preferably, the device further includes two sliders, two push rods, and a gate. The two sliders are slidably mounted on the left and right sides of the frame. The rear ends of the two push rods are connected to the two sliders respectively, and the front ends of the two push rods extend into the chamber of the dry soil box. The gate is mounted on the front ends of the two push rods and can be opened from inside the chamber of the dry soil box to close the soil outlet. When soil adheres to the surface of the pressure roller, the two sliders are moved forward, causing the two sliders to drive the two push rods and the gate to move forward, thereby opening the soil outlet. At this time, the dry soil in the chamber of the dry soil box can be dispersed into the collection tank through the soil outlet and the guide channel. When no soil adheres to the surface of the pressure roller, the two sliders are moved backward, causing the two sliders to drive the two push rods and the gate to move backward, thereby closing the soil outlet. At this time, the dry soil in the chamber of the dry soil box cannot be dispersed into the collection tank through the soil outlet and the guide channel, thus reducing the waste of dry soil.
[0010] Preferably, the assembly also includes two springs, two connecting rods, two stop rods, two ratchet wheels, two push cylinders, and two crossbars. One end of each spring is connected to one of the two sliders, and the other end of each spring is connected to the frame. The front ends of each connecting rod are hinged to the two sliders, and stop rods are installed at the rear ends of each connecting rod. Each connecting rod has a long sliding groove. The two ratchet wheels are concentrically mounted on the ends of the central shaft of the pressure roller. The two stop rods mesh with the ratchet teeth of the two ratchet wheels. The fixed ends of the two push cylinders are mounted on the left and right side walls of the frame, and crossbars are installed on the piston rods of each push cylinder. The two crossbars are slidably mounted in the long sliding grooves of the two connecting rods. When the surface of the pressure roller is covered with dirt, the piston rods of the two push cylinders drive the two crossbars to descend. The two crossbars pull the rear ends of the two connecting rods downward, causing the two stop rods to mesh with the two ratchet wheels. At this time, when the pressure roller rolls, it drives the two... Two ratchet wheels rotate synchronously. The ratchet teeth of two ratchet wheels engage with two stop rods, pushing two connecting rods forward. The two connecting rods push two sliders forward, and the two sliders push the gate plate forward through two push rods, causing the gate plate to open the soil outlet. When the ratchet teeth of the two ratchet wheels disengage from the two stop rods, the elastic force of the two springs causes the two sliders to return to their original position, causing the gate plate to reciprocate in opening and closing the soil outlet and pushing dry soil towards the outlet for efficient discharge and to prevent blockage. When there is no soil adhering to the surface of the pressure roller, the piston rods of the two push cylinders push the crossbars upward, and the crossbars push the rear ends of the two connecting rods upward, causing the two stop rods to disengage from the two ratchet wheels. At this time, the elastic force of the two springs pushes the two sliders forward, causing the two sliders to push the gate plate forward through the two push rods, causing the gate plate to close the soil outlet, thus realizing the automatic discharge and closure of dry soil in the dry soil box.
[0011] Preferably, it also includes photoelectric switch one and photoelectric switch two, which are respectively mounted on the frame by brackets. Photoelectric switch one and photoelectric switch two are located on the left and right sides above the scraper, respectively, and are arranged opposite to each other. When the scraper scrapes the soil off the surface of the pressure roller, the soil slides along the scraper towards the collection trough, which causes the soil to block the photoelectric signal between photoelectric switch one and photoelectric switch two, thereby generating a control signal. The controller controls the piston rods of the two push cylinders to retract and descend according to the control signal, so that the two stop rods engage with the two ratchet wheels, thereby realizing the automatic conveying and closing of dry soil in the dry soil box and improving the degree of automation.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The lugs are connected to a tractor or other vehicle, thereby driving the frame to move. The frame drives the pressure roller to roll and compact the area around the dam. During the compaction process, the scraper scrapes off the soil attached to the outer surface of the pressure roller and guides it into the collection trough. The dry soil in the dry soil box is fed into the collection trough through the soil outlet. The crushing mechanism stirs the scraped soil and dry soil in the collection trough, thereby mixing the soil and reducing its moisture content. The mixed soil is scattered on the ground in front of the pressure roller through the mud discharge port at the bottom of the collection trough and is rolled again by the pressure roller. Because the soil moisture content is reduced, the probability of soil re-attaching to the surface of the pressure roller is reduced, and the scraped and broken soil is better bonded to the ground, improving the compaction effect.

The dry soil box 6 is installed on the frame 1, located in front of the collection trough 5. The dry soil box 6 has a chamber for storing dry soil inside, and a soil outlet 7 is provided at the lower end of the side wall of the dry soil box 6, located above the collection trough 5.
[0024] The lug 3 connects to a tractor or other vehicle, thereby moving the frame 1. The frame 1 drives the pressure roller 2 to roll and compact the area around the dam. During the compaction process, the scraper 4 scrapes off the soil attached to the outer surface of the pressure roller 2 and guides it into the collection trough 5. The dry soil in the dry soil box 6 is fed into the collection trough 5 through the soil outlet 7. The crushing mechanism mixes the scraped soil and dry soil in the collection trough 5, thereby blending the soil and reducing its moisture content. The blended soil is scattered on the ground in front of the pressure roller 2 through the mud discharge port at the bottom of the collection trough 5 and is then rolled again by the pressure roller 2. Because the moisture content of the soil is reduced, the chance of the soil re-attaching to the surface of the pressure roller 2 is reduced, and the scraped and broken soil is better bonded to the ground, improving the compaction effect.
[0025] Example 2
[0026] like Figures 1 to 4As shown, based on Embodiment 1, the crushing mechanism includes a shaft 8, multiple stirring rods 9, and a transmission assembly 10. The shaft 8 is rotatably installed in the collection trough 5, and multiple stirring rods 9 are evenly installed on the shaft 8. The multiple stirring rods 9 are located inside the collection trough 5. The shaft 8 and the pressure roller 2 are connected by transmission assembly 10. It also includes a shaft 11, multiple stirring rods 12, and two gears 13. The shaft 11 is rotatably installed in the collection trough 5 and is located in front of the shaft 8.

The two gears 13 are concentrically installed at the ends of the shaft 8 and the shaft 11, and the two gears 13 mesh. It also includes a guide channel 14. The front end of the guide channel 14 is hinged to the soil outlet 7 and communicates with the soil outlet 7. The rear end of the guide channel 14 rests on the multiple stirring rods 12.
[0027] The transmission assembly 10 is a chain drive assembly, belt drive assembly, etc. When the frame 1 drags the pressure roller 2 to roll and compact the ground, the pressure roller 2 drives the shaft 8 to rotate through the transmission assembly 10. The two gears 13 mesh, thereby driving the shaft 8 to rotate through the meshing of the two gears 13. The shaft 11 drives multiple mixing rods 12 to rotate, so that the multiple mixing rods 9 and multiple mixing rods 12 can break up, mix and blend the soil and dry soil, improving the mixing efficiency. The dry soil inside the dry soil box 6 is transported to the collection tank 5 through the soil outlet 7 and the guide channel 14. When the shaft 11 drives the multiple mixing rods 12 to rotate, the multiple mixing rods 12 move the rear end of the guide channel 14 up and down, so that the dry soil transported on the guide channel 14 is evenly distributed into the collection tank 5, improving the mixing efficiency of soil and dry soil.
[0028] Example 3
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, based on Embodiment 1, it further includes two sliders 15, two push rods 16, and a gate 17. The two sliders 15 are slidably mounted on the left and right sides of the frame 1. The rear ends of the two push rods 16 are respectively connected to the two sliders 15, and the front ends of the two push rods 16 extend into the chamber of the dry soil box 6. The gate 17 is mounted on the front ends of the two push rods 16 and can be opened from inside the chamber of the dry soil box 6 to close the soil outlet 7. It also includes two springs 18, two connecting rods 19, two stop rods 20, two ratchet wheels 21, two push cylinders 22, and two crossbars 23. One end of the two springs 18 is respectively connected to the two sliders 15, and the other end of the two springs 18 is connected to the frame 1. The front ends of the two connecting rods 19 are respectively hinged to the two sliders 15. Both connecting rods 19 have stop bars 20 installed at their rear ends. Both connecting rods 19 have long sliding grooves. Two ratchet wheels 21 are concentrically installed on the ends of the central shaft of the pressure roller 2. The two stop bars 20 mesh with the ratchet teeth of the two ratchet wheels 21. The fixed ends of the two push cylinders 22 are installed on the left and right side walls of the frame 1. Crossbars 23 are installed on the piston rods of the two push cylinders 22. The two crossbars 23 are slidably installed in the long sliding grooves of the two connecting rods 19. The system also includes photoelectric switch one 24 and photoelectric switch two 25. Photoelectric switch one 24 and photoelectric switch two 25 are installed on the frame 1 through brackets. Photoelectric switch one 24 and photoelectric switch two 25 are located on the left and right sides above the scraper 4, and photoelectric switch one 24 and photoelectric switch two 25 are arranged opposite to each other.
[0030] When soil adheres to the surface of the pressure roller 2, the scraper 4 scrapes the soil off the surface of the pressure roller 2. The soil slides along the scraper 4 towards the collection trough 5, causing the soil to block the photoelectric signal between photoelectric switch 1 24 and photoelectric switch 25, thereby generating a control signal. The controller controls the piston rods of the two push cylinders 22 to retract and descend according to the control signal, so that the two stop rods 20 engage with the two ratchet wheels 21. At this time, when the pressure roller 2 rolls, it drives the two ratchet wheels 21 to rotate synchronously. The ratchet teeth of the two ratchet wheels 21 engage with the two stop rods 20 to push the two connecting rods 19 forward. The two connecting rods 19 push the two sliders 15 forward. The two sliders 15 push the gate 17 forward through the two push rods 16, so that the gate 17 opens the soil outlet 7. When the ratchet teeth of the two ratchet wheels 21 disengage from the two stop rods 20, the springs of the two springs 18... The force causes the two sliders 15 to reset, causing the gate 17 to reciprocate in opening and closing the soil outlet 7, and pushing the dry soil towards the soil outlet 7, so that the dry soil is discharged efficiently and the soil outlet 7 is not blocked. When there is no soil attached to the surface of the pressure roller 2, the photoelectric signal between photoelectric switch 1 24 and photoelectric switch 25 is normal, thereby generating a control signal. The controller controls the piston rods of the two push cylinders 22 to extend according to the control signal, pushing the crossbar 23 upward. The crossbar 23 pushes the rear ends of the two connecting rods 19 upward, so that the two stop rods 20 disengage from the two ratchet 21 respectively. At this time, the elastic force of the two springs 18 pushes the two sliders 15 forward, so that the two sliders 15 push the gate 17 forward through the two push rods 16, so that the gate 17 closes the soil outlet 7, realizing the automatic discharge and closure of the dry soil in the dry soil box 6.
[0031] like Figures 1 to 7As shown, this utility model discloses a dam filling and compaction device. During operation, the lug 3 is first connected to a tractor or other vehicle, thereby moving the frame 1. The frame 1 drives the pressure roller 2 to roll and compact the area around the dam. During compaction, the scraper 4 scrapes off the soil adhering to the outer surface of the pressure roller 2 and guides it into the collection trough 5. The soil on the scraper 4 then blocks the photoelectric signal between photoelectric switch 1 24 and photoelectric switch 25, generating a control signal. The controller, based on the control signal, controls the piston rods of the two push cylinders 22 to contract and descend, causing the two stop rods 20 to engage with the two ratchet wheels 21. At this time, the rolling of the pressure roller 2 drives the two ratchet wheels 21 to rotate synchronously. The ratchet teeth of the two ratchet wheels 21 engage with the two stop rods 20, pushing the two connecting rods 19 forward. The two connecting rods 19 push the two sliders 15 forward, and the two sliders 15 push the gate through the two push rods 16. The plate 17 moves forward, causing the gate 17 to open the soil outlet 7. When the ratchet teeth of the two ratchet 21 disengage from the two stop bars 20, the elastic force of the two springs 18 causes the two sliders 15 to reset, causing the gate 17 to reciprocate in opening and closing the soil outlet 7 and pushing the dry soil towards the soil outlet 7, so that the dry soil is discharged efficiently and the soil outlet 7 is not blocked. The dry soil is then fed into the collection tank 5 through the soil outlet 7 and the guide channel 14. Then, the crushing mechanism stirs the soil and dry soil scraped off in the collection tank 5, thereby mixing the soil and reducing its moisture content. The mixed soil is scattered on the ground in front of the pressure roller 2 through the mud discharge port at the bottom of the collection tank 5 and is crushed again by the pressure roller 2. Since the soil moisture content is reduced, the probability of the soil re-adhering to the surface of the pressure roller 2 is reduced. Finally, the soil that has been scraped off and broken up is better able to adhere to the ground.
[0032] The main functions achieved by this utility model are:
[0033] 1. By mixing dry soil and mud, the moisture content of the mud is reduced, mud re-adhesion is reduced, and the compaction effect is improved.
[0034] 2. It can automatically transport dry soil, avoiding waste of dry soil;
