Description

Technical Field

[0001] This utility model relates to the technical field of leveling devices, specifically a side-mounted movable pit-filling and leveling device. Background Technology

[0002] In numerous engineering fields such as road construction, building site leveling, and farmland reclamation, soil filling and leveling is a crucial foundational task. Traditional methods of filling and leveling primarily rely on manual labor. Workers use simple tools like shovels and rakes to initially fill the pits with soil, then repeatedly level the surface to achieve a relatively smooth state. However, this method has many drawbacks. Manual operation is extremely inefficient. Large-scale filling and leveling operations require a significant investment of manpower, consuming considerable time and energy, and are physically demanding, leading to worker fatigue and impacting work progress and quality. Furthermore, the precision of manual leveling is difficult to guarantee. Due to the randomness and instability of manual operation, it is difficult to achieve a highly uniform and smooth soil surface, often resulting in uneven areas. For projects with high flatness requirements, such as highway pavement construction and airport runway construction, manual leveling cannot meet their stringent construction standards.

[0003] With the development of technology, some mechanized pit-filling and leveling equipment has emerged. However, most of these devices are single-function, only capable of simple filling or leveling actions, and cannot make intelligent adjustments based on the actual soil conditions. For example, some equipment cannot automatically adjust its working force and method when dealing with soil of different heights and densities. This results in either ineffective soil breaking up or excessive soil breaking up when handling soil of a certain height, leading to uneven soil distribution and affecting the subsequent leveling effect. Moreover, existing equipment also lacks operational flexibility and is difficult to adapt to complex and changing construction environments. It often cannot effectively complete pit-filling and leveling operations in corners or narrow areas.

[0004] To address the aforementioned issues, we propose a laterally mounted, movable pit-filling and leveling device. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5This utility model provides a technical solution: a laterally mounted movable pit-filling and leveling device, including a main frame 1, a plowing and leveling device 2, a soil loosening device 3, and a detection device 4; the top surface of the main frame 1 is connected to the detection device 4; the soil loosening device 3 and the plowing and leveling device 2 are connected inside the main frame 1; the detection device 4, the soil loosening device 3, and the plowing and leveling device 2 are arranged sequentially along the travel direction of the main frame 1.

[0018] First, the soil height at the filling site is detected by the detection device 4. Based on the soil height analysis, the loosening device 3 is used to break up the soil in a targeted manner. Finally, the plowing and leveling device 2 is used to further break up and level the soil.

[0019] The main frame 1 includes a vehicle mounting base plate 11, a first connecting plate 12, a top plate 13, a second connecting plate 14, a first support plate 15, and a second support plate 16. The top surface of the first connecting plate 12 is connected to the vehicle mounting base plate 11. The plowing and leveling device 2 is connected between the first connecting plate 12 and the second connecting plate 14. The top surface of the second connecting plate 14 is connected to the first support plate 15. The first support plate 15 is connected to the vehicle mounting base plate 11 through the top plate 13. The top surface of the second connecting plate 14 is also connected to the second support plate 16. The second support plate 16 is connected to the vehicle mounting base plate 11 through the detection device 4. The first support plate 15 is connected to the second support plate 16 through a connecting rod 17. The outer circumference of the connecting rod 17 is connected to one end of the loosening device 3. A fixing ring is connected to the top surface of the top plate 13 away from the vehicle mounting base plate 11, which can be used to fix some auxiliary tools or cables directly connected to the vehicle, avoiding the entire device from tilting away from the vehicle due to weight.

[0020] The vehicle mounting base plate 11 is also provided with multiple connection modules on its side. The connection modules adopt a design with built-in reinforcing ribs to enhance stability and connect to the vehicle.

[0021] The plowing and leveling device 2 includes a scraping plate 21, a first plowing rod 22, and a second plowing rod 23; the scraping plate 21 connects the first connecting plate 12 and the second connecting plate 14; a plurality of the first plowing rods 22 and a plurality of the second plowing rods 23 are evenly arranged on one side wall of the scraping plate 21 for preliminary breaking up and leveling of the soil.

[0022] The first plowing rod 22 and the second plowing rod 23 have different shapes. The first plowing rod 22 has a conical tip design, which has a better breaking up effect; the second plowing rod 23 has a flat tip design, which has a better bulldozing effect. The two structures are as follows: Figure 2 The installation shown can improve the effect of loosening and dispersing the soil.

[0023] The soil loosening device 3 includes an auger roller 31, an auger control motor 32, an electric cylinder 33, an auxiliary connecting plate 34, an auger bearing seat 35, and a rotating connecting plate 36. One end of the auger roller 31 is connected to the auger control motor 32 through the auger bearing seat 35. The auger control motor 32 can be an existing servo motor, which can achieve forward and reverse rotation and provide stable power to the auger roller 31 to effectively break up the soil. The other end of the auger roller 31 is rotatably connected to one side of the rotating connecting plate 36. The top of the auger bearing seat 35 is rotatably connected to the drive end of the electric cylinder 33 through the auxiliary connecting plate 34. The electric cylinder 33 is a common servo electric cylinder with moderate thrust and adjustable stroke, which can accurately control the position and movement of the auger roller 31. The auger control motor 32 is detachably connected to the side of the auxiliary connecting plate 34; the fixed end of the electric cylinder 33 is sleeved on the outer circumference of the connecting rod 17; the second connecting plate 14 has a movable groove for one end of the auger roller 31 to move; the other side of the rotating connecting plate 36 is rotatably connected to the inner side of the first connecting plate 12.

[0024] The rotating connecting plate 36 includes a flange bearing seat, a mounting connecting plate, and a rotating frame. The flange bearing seat is connected to the other end of the auger roller 31. One side of the mounting connecting plate is connected to the flange bearing seat, and the other side of the mounting connecting plate is connected to the rotating frame. The rotating frame is rotatably connected to the inner side of the first connecting plate 12.

[0025] The auxiliary connecting plate 34 adopts an L-shaped structure. The side of the auxiliary connecting plate 34 can be connected to the auger control motor 32. The top surface of the auxiliary connecting plate 34 is connected to the drive end of the electric cylinder 33 through a small bearing seat. The electric cylinder 33 has preset values, and the values ​​of the push-out distance and pull-back distance of the drive end of the electric cylinder 33 are fixed.

[0026] The auger roller 31 can break up and transport the soil, and unlike conventional augers, it does not need to transport the soil completely from one end to the other, so it does not need an outer shell.

[0027] The auger roller 31 is positioned as follows: Figure 3 As shown, combined with Figure 1 It can be seen that when the auger roller 31 rotates in the same direction as the vehicle wheel, the auger 31 rotates forward and the soil is conveyed from the side closer to the vehicle to the side closer to the second support plate 16; when the auger roller 31 rotates in the opposite direction to the vehicle wheel, the auger 31 rotates in reverse and the soil is conveyed from the side closer to the second support plate 16 to the side closer to the vehicle.

[0028] The detection device 4 includes a mounting box 41, a lead screw motor 42, a laser sensor 43, a bidirectional lead screw 44, and a mounting block 45. The mounting box 41 is connected to the top surface of the main frame 1. The bidirectional lead screw 44 is rotatably connected inside the mounting box 41. One end of the bidirectional lead screw 44 is connected to the drive end of the lead screw motor 42. The lead screw motor 42 is a servo motor, which can achieve forward and reverse rotation and can precisely control the rotation of the bidirectional lead screw 44.

[0029] The other end of the bidirectional lead screw 44 is rotatably connected to the inner side of the mounting box 41. The bidirectional lead screw 44 includes two opposing threads, and a mounting block 45 is connected to each of the two threads of the bidirectional lead screw 44. The bottom surface of the mounting block 45 is connected to the laser sensor 43. The laser sensor 43 is a laser rangefinder sensor of model LDM301, which has high measurement accuracy, fast response speed, and can accurately detect soil height.

[0030] The laser sensor 43 has a preset value, which is a standard distance. If the measured data is less than the preset value, it means that the ground height is too high. If the measured data is greater than the preset value, it means that the ground height is too low.

[0031] Turning on the lead screw motor 42 can enable the two laser sensors 43 to move relative to each other or in opposite directions, thereby enabling a wide range of measurements of the soil below.

[0032] The laser sensor 43 is electrically connected to the controller on the vehicle, enabling the controller to display data. The operator then controls the lead screw motor 42, the electric cylinder 33, and the auger control motor 32 based on the changes in the data.

[0033] The length of the cable chain 5 needs to meet the lifting range of the auxiliary connecting plate 34 so as not to affect the normal operation of the auger control motor 32.

[0034] Working principle: The soil loosening device 3 is connected to the vehicle via the cable chain 5. As the vehicle moves, the main frame 1 follows the vehicle. The detection device 4 uses the laser sensor 43 to detect the soil height at the filling site. When the value of the laser sensor 43 on the side closer to the second support plate 16 is less than a predetermined value, it indicates that the soil height on that side is too high and needs to be further broken up and soil added to the other side. At this time, the electric cylinder 33 pushes the auxiliary connecting plate 34 towards the ground, causing the auger roller 31 to move downwards. The auger 31 reverses, causing the soil to be transported from the side closer to the second support plate 16 to the side closer to the vehicle. Finally, the soil is further broken up and leveled by the scraper plate 21, the first plowing rod 22, and the second plowing rod 23 of the plowing and leveling device 2, so that the soil is evenly distributed.

[0035] If the value of the laser sensor 43 on the side near the vehicle is less than the predetermined value, it indicates that the soil height on the side near the vehicle is higher, while the soil height on the side near the second support plate 16 may be lower. At this time, the electric cylinder 33 retracts its drive end upward, causing the end of the auger roller 31 near the second support plate 16 to be lifted upward, preventing the soil on the side near the second support plate 16 from being further dispersed. At the same time, the auger control motor 32 drives the auger roller 31 to rotate. The auger 31 rotates forward, dispersing the soil on the side near the vehicle and causing the soil to gather on the side near the second support plate 16, thereby completing the dispersal and flattening of the soil with a certain height.
