Description

Technical Field

[0001] This invention belongs to the field of farmland road compaction technology, and particularly relates to a compaction construction device for farmland road construction. Background Technology

[0002] In the compaction of narrow farmland roads less than 4 meters wide, hand-held mini road rollers are commonly used. However, these machines have the following drawbacks in actual farmland road compaction operations: 1. Soil at the road edge is prone to lateral slippage, and current limiting methods are inefficient. Since the roadbed is higher than the surrounding farmland or ditches, the vertical compressive force applied by the roller's compaction wheel is easily converted into lateral force, causing the edge soil to slip and collapse outwards, resulting in loss of roadbed fill material and insufficient edge compaction. Existing technologies often use temporary side barriers such as wooden piles or sheet piles for limiting, requiring separate erection and dismantling processes, which are cumbersome, time-consuming, and lack linkage with the roller, making them unsuitable for continuous compaction operations.

[0003] 2. The equipment is prone to deviation during movement, and existing guidance structures are ineffective and have high operational requirements. Hand-held mini road rollers rely on manual directional control, and are highly susceptible to deviation due to factors such as roadbed smoothness and compaction wheel vibration. This deviation is particularly problematic during edge compaction, which can lead to insufficient compaction width, slope collapse, or even equipment overturning. Existing methods, such as adding guide wheels and positioning markers, either lack effective lateral restraint resulting in poor guidance or require highly skilled operators, making them unsuitable for the actual operational scenarios of farmland road construction.

[0004] In summary, existing technologies cannot simultaneously solve the problems of lateral soil displacement at the edges of compacted soil and equipment deviation in narrow farmland roads, and targeted improvements are urgently needed to enhance construction quality and operational efficiency. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a compaction construction device for farmland road construction, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: The present invention provides a compaction construction device for farmland road construction, including a frame, a compaction system, a side limiting system, and an anti-deviation system. The compaction system includes two compaction rollers rotatably mounted on the lower side of the frame and distributed front to back. A drive assembly for driving the two compaction rollers to rotate is also provided on the frame. The side limiting system includes an H-shaped bracket located on the right side of the frame. The H-shaped bracket is detachably connected to two connecting columns. A side limiting plate is fixedly connected to the lower ends of the two connecting columns. The side limiting plate has a wave-like structure on the side near the compaction rollers. Two symmetrically arranged first reinforcing plates are connected between the side limiting plate and the H-shaped bracket. A second reinforcing plate is connected between the frame and the corresponding connecting columns. The anti-deviation system includes two rotating frames located on the left side of the frame and distributed front to back. An anti-deviation insert plate is connected between the two rotating frames. During construction, the side limiting plate is rigidly attached to the side wall of the road edge. The first reinforcing plate, H-shaped bracket and connecting column form a triangular structure to provide primary support for the side limiting plate. The second reinforcing plate, frame and connecting column form a triangular structure to provide secondary support for the side limiting plate. At the same time, the lower end of the anti-deviation insert plate is inserted obliquely into the hard soil layer. During the rolling compaction process, the soil compaction generates a thrust on the right side of the anti-deviation insert plate, which counteracts the squeezing force on the left side of the side limiting plate.

[0007] According to an advantageous embodiment, two scrapers symmetrically distributed front and rear are fixedly mounted on the lower middle part of the frame via a connecting frame.

[0008] According to an advantageous embodiment, the drive assembly includes a driver fixedly mounted on the upper side of the frame, the output shaft of which is connected to one end of the two compaction rollers via a sprocket set.

[0009] According to an advantageous embodiment, two guide sleeves distributed front and rear are fixedly provided in the middle of the H-shaped bracket. The guide sleeves and the H-shaped bracket are provided with a common insertion hole. The connecting column is slidably connected to the corresponding insertion hole, and the connecting column and the corresponding guide sleeve are fixedly connected by bolts and nuts.

[0010] According to an advantageous embodiment, one end of the first reinforcing plate is rotatably connected to the right side of the side limiting plate, and the other end of the first reinforcing plate is threaded with a first locking post, which is slidably inserted into the H-shaped bracket.

[0011] According to an advantageous embodiment, one end of the second reinforcing plate is rotatably connected to the front side and right side of the frame, and the other end of the second reinforcing plate is threaded with a second locking post, which is slidably inserted into the corresponding connecting post.

[0012] According to an advantageous embodiment, the wave structure of the side limiting plate includes a ramp section, two crest sections and a trough section, the ramp section, crest section, trough section and crest section are connected sequentially, the ramp section and the trough section are respectively facing the two compaction rollers, and the ramp section is at the foremost position, one crest section is between the two compaction rollers, and the other crest section is at the last position.

[0013] According to an advantageous embodiment, the rotating frame includes a top support assembly disposed on the left side of the frame, and a rotating seat is rotatably disposed on the left side of the frame near the top support assembly. The rotating seat is connected to the top support assembly, and two connecting rods are connected to the rotating seat via an adjustment assembly. One end of the connecting rod is fixedly connected to an anti-deviation plate.

[0014] According to an advantageous embodiment, the top support assembly includes a top support plate, and a plurality of left-right distributed threaded grooves are provided on the rear side of the frame. The top support plate is threadedly connected and fixed to the corresponding threaded grooves by locking bolts. A first guide rod is fixedly provided on the side of the rotating seat facing the top support plate, and a top support slider is slidably connected on the first guide rod. The top support slider is hinged to the top support plate.

[0015] According to an advantageous embodiment, the rotating seat has a waist hole extending along its length. An adjusting screw is rotatably disposed in the waist hole, and two second guide rods are fixedly disposed therein. Two connecting sliders are threadedly connected to the adjusting screw. The connecting sliders are slidably connected to the second guide rods, and the connecting sliders are fixedly connected to the corresponding connecting rods.

[0016] Compared with the prior art, the compaction construction device for farmland road construction provided by the embodiments of the present invention has the following beneficial effects: 1. In the present invention, through the coordinated cooperation of the side limiting system and the anti-deviation system, the dual effects of precise limiting of edge soil and precise positioning of device direction are achieved. This can not only completely solve the problems of roadbed loss and insufficient compaction caused by lateral displacement of edge soil, but also effectively avoid safety hazards and construction quality defects caused by equipment deviation. At the same time, it simplifies the construction process, lowers the operation threshold, and greatly improves the quality, efficiency and practicality of compaction construction of narrow farmland roads, adapting to the needs of actual construction scenarios.

[0017] 2. In this invention, by integrating the side limiting system with the frame and using a double triangular support structure combined with a wave-shaped limiting surface, continuous and efficient limiting can be achieved simultaneously with the compaction operation. At the same time, stress is effectively dispersed and soil pressure is buffered, ensuring that the soil at the road edge does not slip or collapse during the compaction process, thus ensuring the edge compaction degree and the stability of the roadbed fill material, and greatly improving construction efficiency.

[0018] 3. In this invention, through the synergistic effect of the anti-deviation system and the side limiting system, the reverse force generated by the anti-deviation insert plate inserted into the soil is used to counteract the lateral extrusion force on the side limiting plate, which greatly reduces the difficulty of operating the device, reduces the risk of device deviation, improves the stability of the device during compaction, and avoids insufficient compaction width or equipment tipping over.

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail.

[0028] See also Figure 1 , Figure 2 and Figure 4A compaction device for farmland road construction is disclosed, used to compact soil roads. The device includes a frame 1, on which a compaction system 2 is mounted. The compaction system 2 includes two compaction rollers 21 rotatably mounted on the lower side of the frame 1 and distributed along the front-to-back direction. Two scrapers 5, symmetrically distributed along the front-to-back direction, are fixedly mounted on the lower center of the frame 1 via a connecting frame. The scrapers 5 are used to scrape away soil adhering to the surface of the compaction rollers 21. A drive assembly 22 is also mounted on the frame 1, controlling the rotation of the two compaction rollers 21, thereby moving the entire device.

[0029] See Figure 2 The drive assembly 22 includes a driver fixedly mounted on the upper side of the frame 1. The output shaft of the driver is connected to one end of the two compaction rollers 21 via a sprocket set (not shown in the figure). The driver in this solution uses a diesel engine, and the specific model can be freely selected according to actual needs.

[0030] See Figure 1 and Figure 2 To prevent excessive lateral slippage of the road edge during compaction, a side limiting system 3 is installed on the right side of the frame 1. The side limiting system 3 includes an H-shaped bracket 31 located on the right side of the frame 1. Two connecting posts 32 are detachably connected to the H-shaped bracket 31, and a side limiting plate 33 is fixedly connected to the lower ends of the two connecting posts 32. An arc-shaped guide strip is welded to the foremost side of the side limiting plate 33, and the side of the side limiting plate 33 closest to the compaction roller 21 is designed with a wave structure 34. Two first reinforcing plates 35, symmetrically distributed front and rear, are connected between the side limiting plate 33 and the H-shaped bracket 31, and a second reinforcing plate 36 is connected between the frame 1 and the corresponding connecting posts 32.

[0031] In operation, the side limiting plate 33 can be adjusted upwards to achieve suspension when idle. In operation, the side limiting plate 33 is attached to the right edge of the road: the first reinforcing plate 35, the H-shaped bracket 31, and the connecting column 32 form a triangular support structure, providing primary support for the side limiting plate 33. The second reinforcing plate 36, the frame 1, and the connecting column 32 form another triangular support structure, providing secondary support for the side limiting plate 33. Through this dual support structure, the support strength of the side limiting plate 33 can be significantly improved.

[0032] During the compaction and movement of the device, the operator maneuvers the entire device. Due to the restriction and guidance effect of the side limiting plate 33, the entire device can move smoothly along the road extension direction. As the loose soil is compacted by the rolling of the compaction roller 21, the limiting effect of the side limiting plate 33 prevents excessive lateral slippage. At the same time, the wave structure 34 on the side of the side limiting plate 33 near the compaction roller 21 not only effectively limits the soil but also disperses stress, preventing local stress concentration that could damage the limiting structure.

[0033] It should be noted that the side limiting plate 33 must completely cover the loose soil layer 100 to be compacted in the height direction, and its lower end must extend downwards for a certain length and cover the hard soil layer below, so as to prevent the originally stable hard soil layer below from collapsing due to the compaction pressure during the compaction process.

[0034] See Figure 1 and Figure 2 To prevent the side limiting plate 33 from being subjected to excessive horizontal compressive force, which could cause the entire device to shift outwards towards the road edge, an anti-deviation system 4 is also provided on the frame 1. The anti-deviation system 4 includes two rotating frames 41 located on the left side of the frame 1 and symmetrically distributed along the front and back, with an anti-deviation insert 42 connecting the two rotating frames 41.

[0035] In actual operation, the anti-deviation plate 42 can be lifted and kept suspended in the air by rotating the frame 41 when it is not in use.

[0036] In operation, the anti-deviation insert plate 42 is rotated and tilted into the soil in the middle section of the road by the rotating frame 41. The lower end of the anti-deviation insert plate 42 needs to penetrate the loose soil layer 100 and insert into the underlying hard soil layer 200 to a certain depth (usually 5cm). The anti-deviation insert plate 42 moves synchronously with the frame 1. During the compaction of the soil by the compaction roller 21, the compacted soil will exert a horizontal leftward thrust on the anti-deviation insert plate 42. This leftward thrust received by the anti-deviation insert plate 42 inserted into the soil can significantly offset the rightward squeezing force received by the side limiting plate 33. Figure 7 As shown. Through the combined action of the side limiting plate 33 and the anti-deviation insert plate 42, the soil at the edge of the road can be quickly and efficiently limited during the compaction process, and the compaction direction of the device can be accurately positioned to effectively prevent the device from deviating.

[0037] See Figure 1 and Figure 2 Two guide sleeves distributed along the front-to-back direction are welded and installed in the middle of the H-shaped bracket 31. The guide sleeves and the H-shaped bracket 31 are provided with insertion holes. The connecting column 32 is slidably connected to the corresponding insertion hole, and the connecting column 32 is fixedly connected to the corresponding guide sleeve by bolts and nuts, so as to realize the detachable connection between the connecting column 32 and the H-shaped bracket 31.

[0038] See Figures 1-3 One end of the first reinforcing plate 35 is rotatably connected to the right side of the side limiting plate 33, and the other end of the first reinforcing plate 35 is threadedly connected to a first locking post 37, which is slidably inserted into the side wall of the H-shaped bracket 31. Through holes are provided in the middle section of the first reinforcing plate 35 and at corresponding positions on the H-shaped bracket 31, for use with the first locking post 37 to lock and unlock the first reinforcing plate 35.

[0039] See Figures 1-3 One end of the second reinforcing plate 36 is rotatably connected to the front right side of the frame 1, and the other end of the second reinforcing plate 36 is threadedly connected to the second locking post 38. The second locking post 38 is slidably inserted into the corresponding connecting post 32 to realize the locking and unlocking of the second reinforcing plate 36.

[0040] In specific operation, when the side limiting plate 33 is idle and needs to be lifted, the bolts on the guide sleeve can be unlocked first, and then the first reinforcing plate 35 and the second reinforcing plate 36 can be unlocked respectively through the first locking post 37 and the second locking post 38. Then, the side limiting plate 33 is moved upward to adjust its height. Finally, the first locking post 37 is inserted into the corresponding through hole to achieve the suspension and fixation of the side limiting plate 33, which is convenient for the device to be moved and stored when idle.

[0041] See Figure 2 and Figure 5 The wave structure 34 of the side limiting plate 33 includes a ramp section 341, two crest sections 342, and a trough section 343, which are connected sequentially in the front-to-back direction. The ramp section 341 and trough section 343 correspond to the two compaction rollers 21, with the ramp section 341 at the foremost position, one crest section 342 between the two compaction rollers 21, and the other crest section 342 at the rearmost position. This structural design avoids excessive instantaneous compressive force on the side limiting plate 33 during the limiting process: when the compaction rollers 21 compact the soil and push it towards the side limiting plate 33, the ramp section 341 and trough section 343 can accommodate more soil, acting as a buffer against pressure. Subsequently, the two crest sections 342 can further refine the soil, ensuring the compaction quality of the road edge.

[0042] See Figure 2 , Figure 3 and Figure 6The rotating frame 41 includes a top support assembly 411 located on the left side of the frame 1. A rotating seat 412 is rotatably mounted on the left side of the frame 1 near the top support assembly 411, and the rotating seat 412 is connected to the top support assembly 411. Two connecting rods 414 are connected to the rotating seat 412 via an adjusting assembly 413, and one end of each connecting rod 414 is fixedly connected to an anti-deviation insert 42. During operation, the top support assembly 411 pushes the rotating seat 412 to rotate, thereby causing the anti-deviation insert 42 to rotate and insert into the soil, thus activating the anti-deviation function.

[0043] It should be noted that the lower end of the connecting rod 414 is located in the loose soil, and the resistance it generates during the movement of the frame 1 is negligible and will not affect the normal movement and compaction operation of the device.

[0044] See Figure 3 and Figure 6 The top support assembly 411 includes a top support plate 4111. Multiple threaded grooves distributed along the left-right direction are provided on the rear side of the frame 1. The top support plate 4111 is threadedly connected to the corresponding threaded grooves via locking bolts, thus fixing and adjusting the position of the top support plate 4111 on the frame 1. A first guide rod 4112 is fixedly installed on the side of the rotating seat 412 opposite to the top support plate 4111. A top support slider 4113 is slidably connected to the first guide rod 4112, and the top support slider 4113 is hinged to the top support plate 4111. By adjusting the installation position of the top support plate 4111 within the threaded grooves, the rotating seat 412 can be rotated around its rotation axis, thereby adjusting the tilt angle and insertion depth of the anti-deviation insert plate 42 into the soil.

[0045] See Figure 6 The rotating base 412 has a waist hole extending along its length. An adjusting screw 4131 is rotatably installed within the waist hole, and two second guide rods 4132 are also fixedly installed within the waist hole. Two connecting sliders 4133 are threadedly connected to the adjusting screw 4131. The connecting sliders 4133 are slidably connected to the second guide rods 4132, and the connecting sliders 4133 are fixedly connected to the corresponding connecting rods 414. One end of the adjusting screw 4131 movably passes through the rotating base 412 and is equipped with a rotating disk. The operator can rotate the adjusting screw 4131 by rotating the rotating disk, thereby driving the two connecting sliders 4133 to move along the second guide rods 4132, realizing fine adjustment of the left and right position of the anti-deviation insert 42, ensuring that the anti-deviation insert 42 can be accurately inserted into the middle section of the road to achieve the best anti-deviation effect.

[0046] The specific construction steps for this device to compact farmland roads are as follows: First, a layer of loose soil with a thickness of 15-20cm is laid on the road surface through an external paving device or manual labor, and the soil surface is kept as flat as possible to prepare for subsequent compaction operations.

[0047] S1. Lower the side limiting plate 33: Move the compaction device to the right side of the road, then lower the side limiting plate 33 and lock it in place using the relevant locking structure. Readjust the overall position of the compaction device to ensure that the side limiting plate 33 fits tightly against the right edge of the road to ensure the limiting effect.

[0048] S2. Lower the anti-deviation insert 42: Unlock the locking bolts of the top support plate 4111, and push the rotating seat 412 to rotate through the top support assembly 411, causing the anti-deviation insert 42 to rotate and insert into the soil. After the anti-deviation insert 42 has reached the required insertion depth, tighten the locking bolts again to fix the top support plate 4111, completing the installation and locking of the anti-deviation insert 42.

[0049] S3. Soil compaction operation: The worker holds the handle on the machine frame 1 and controls the compaction roller 21 to move slowly along the edge of the road to compact the soil on the right edge of the road, ensuring that the soil at the edge is compacted evenly and densely.

[0050] S4. Repeat steps S1-S3 above to compact the soil on the left edge of the road. After the soil on both sides of the road has been compacted, lift and fix the side limiting plate 33 and the anti-deviation insert plate 42 again. Then, compact the soil in the middle section of the road to ensure that the compaction quality of the entire road surface is consistent.

[0051] S5. Layered Compaction: After the single layer of soil is compacted, loose soil is laid again on the road surface, and steps S1-S4 above are repeated to compact the next layer of soil. This process is repeated until the compacted thickness of the road reaches the preset design thickness, completing the compaction work for the entire farmland road.

[0052] In addition, it should be noted that the compaction device in this solution has added a side limiting system 3 and an anti-deviation system 4 compared to the existing hand-held compactor. However, the added components are basically conventional mechanical parts. Although this increases the cost, the additional cost is negligible compared to the improved efficiency and quality in the process of compacting farmland roads and the fact that it can be used for a long time.
