Description

Technical Field

[0001] This invention relates to the field of civil engineering machinery technology, specifically to a soil and rock slope compaction device. Background Technology

[0002] Earthwork slope compaction is a core process in road and building engineering, directly determining the stability and service life of the slope. Its compaction quality is directly related to the project's resistance to landslides and settlement, and is a key link in ensuring project safety. However, existing compaction devices have many technical bottlenecks in actual operation, making it difficult to meet the needs of efficient and high-quality construction.

[0003] The core problem with traditional equipment is uneven compaction and insufficient cohesion between soil particles. Due to the lack of a dedicated water spraying and moisturizing mechanism, dry soil particles have high friction and poor cohesion. For dry soil, the surface moisture content of the particles is extremely low, making it impossible to form an effective water film bonding layer. The friction between particles increases significantly, making it difficult for particles to move relative to each other and interlock tightly during the rolling process. This directly results in a compaction density far below the design standard. At the same time, the cohesion between particles in dry soil is already weak. Without the lubrication and cementing effect of water, the compacted soil structure has extremely poor stability and insufficient shear strength, resulting in poor compaction effect. In addition, slope areas often contain gravel and other impurities. Existing equipment lacks a pre-cleaning mechanism, and these impurities can easily cause uneven force on the rolling rollers, further reducing the compaction quality.

[0004] Therefore, this solution proposes a compaction device for earthwork slopes. Summary of the Invention

[0005] Technical problem solved: In view of the shortcomings of the existing technology, the present invention provides an earthwork slope compaction device to solve the problem of poor compaction effect when the soil is not wetted.

[0006] Technical solution: To achieve the above objectives, the present invention is implemented through the following technical solution: an earth and rock slope compaction device, comprising a road roller body, a compaction roller movably installed at the bottom of the road roller body, a wetting component provided at one end of the road roller body, the wetting component comprising a support frame fixedly connected to the road roller body, a limit block fixedly installed at the top of the support frame, and a water tank provided at the top of the limit block; The top of the support frame is provided with a water inlet that communicates with the inner cavity of the water tank. The lower part of the support frame is provided with a liquid storage tank that communicates with the water inlet. The bottom of the liquid storage tank is provided with a plurality of first leak holes at equal intervals. Each of the plurality of first leak holes is provided with a dripping component. One end of the support frame is arc-shaped, and a drainage groove is provided at the lower part of the arc-shaped surface of the support frame. The dripping assembly includes a sleeve disposed inside a first leak hole, a blocking block for controlling the flow of water is disposed at the bottom of the sleeve, and a plurality of guide grooves are circumferentially formed on the outer side of the blocking block. Water from the water tank is dispersed and transported to the bottom of the support frame through the first drainage holes equidistantly opened at the bottom of the support frame during the movement of the compaction roller, thereby pre-wetting the soil that the compaction roller needs to compact and improving the compaction effect. The arc-shaped structure at one end of the support frame allows one end of the support frame to fit against the lower outer surface of the compaction roller. Under the action of the drainage groove, a water film is formed on the lower outer surface of the compaction roller, thereby reducing the adhesion of the surface during the movement of the compaction roller. The blocking block and guide groove in the dripping component make the water flow drip at the delivery end.

[0007] Furthermore, the top of the support frame is fixedly connected to one end of the roller body, a transverse groove is provided on one side of the support frame, a slide plate is slidably connected in the transverse groove, the bottom of the slide plate is slidably connected to the top of the liquid storage tank, and an extrusion plate is fixedly connected to the top of the slide plate.

[0008] Furthermore, a right-angle plate is symmetrically and movably inserted through the middle of one side of the support frame. The ends of the two right-angle plates are fixedly connected to a second connecting rod. The outer peripheral surfaces of the two second connecting rods are fitted with a first compression spring at both ends, which abut against the right-angle plate and the support frame respectively. One end of the two second connecting rods is fixedly connected to a limiting plate that is movably inserted into the support frame. The upper surface of the limiting plate is in contact with one end of the water inlet.

[0009] Furthermore, the dripping assembly also includes a vertical rod that movably penetrates the sleeve. The top of the vertical rod is fixedly connected to a squeezing head that movably engages with the first leak hole. The top of the squeezing head is hemispherical, and a plurality of second leak holes are annularly opened on the top of the squeezing head. A horizontal plate is fixedly penetrated through the outside of the vertical rod. The horizontal plate is located inside the first leak hole and its end is fixedly connected to a support frame. A second compression spring is sleeved on the outer circumferential surface of the vertical rod, with its two ends respectively abutting against the horizontal plate and the squeezing head.

[0010] Furthermore, the bottom of the blocking block is hemispherical, the top of the blocking block is conical, and the diameter of the circular hole in the center of the sleeve is larger than that of the vertical rod and smaller than that of the blocking block.

[0011] Furthermore, the bottom sides of the slide plate are provided with inwardly inclined slopes, one side of the extrusion plate is provided with an arc surface for assisting liquid discharge, and a vertical plate is fixedly installed on one side of the bottom of the support frame.

[0012] Furthermore, a drive shaft is provided at one end of the rolling roller, and a first disc is fixedly connected to the end of the drive shaft. A first connecting rod is hinged to the outer surface of the first disc, and one end of the first connecting rod is hinged to the slide plate.

[0013] Furthermore, a cleaning component is provided at one end of the support frame. The cleaning component includes a fixing block. The end of the fixing block is fixedly connected to one side of the support frame. A crossbar is movably passed through the fixing block. Connecting arms are fixedly connected to the outer surfaces of both ends of the crossbar. A horizontal shaft is fixedly passed through one end of each of the two connecting arms. Two second discs are fixedly passed through the side end of the horizontal shaft.

[0014] Furthermore, multiple spring steels are fixedly installed at an annular interval on the inner circumferential surfaces of the two second disks. A connecting plate is movably passed through one end of the horizontal shaft. One side of the connecting plate is in contact with one end surface of the second disk. A screw is rotatably connected to the other end of the connecting plate. The screw is threadedly connected to the connecting arm. A turntable is fixedly installed at one end of the connecting arm. Beneficial effects

[0015] The present invention has the following beneficial effects: 1. Through the mechanical linkage structure of the compaction roller, drive shaft, first disc, first connecting rod, and slide plate, the drive shaft and compaction roller are coaxially fixed to transmit power, causing the first disc to rotate and the first connecting rod to swing back and forth, thereby pulling the slide plate to slide precisely. The linkage structure, together with the first compression spring to provide elastic restoring force, the normally closed water control mechanism with the limit plate tightly attached to the water inlet, and the dripping component including the extrusion head, blocking block, and guide groove for indirect water dripping design, solves the problems of poor compaction quality and low efficiency of manual watering caused by the lack of a dedicated water spraying mechanism in traditional devices. It realizes the synchronous linkage of the wetting component and the compaction operation and indirect water dripping. Wetting causes a water film bonding layer to form on the soil surface, reducing the friction between particles, making the particles tightly interlocked during the rolling process, improving the soil particle cohesion and compaction density, and avoiding the waste of water resources.

[0016] 2. By using an arc-shaped structure that adapts to the outer surface of the support frame and the roller, and combining it with the arc-shaped drainage groove to form a sealed water guiding chamber, and combining the function of the second compression spring in the dripping assembly to drive the squeezing head and the blocking block to reset when there is no external force, the problem of soil sticking to the roller and water flow not being able to be controlled as needed in traditional devices is solved. A stable water film is formed at the bottom of the roller, reducing the coefficient of friction, and the water flow channel can be automatically closed after the roller stops rotating, reducing the amount of soil sticking, while avoiding residual dripping water, and further avoiding water waste.

[0017] 3. The cleaning component, consisting of a second disc providing the mounting base at one end of the support frame and spring steel arranged in a ring, utilizes the elastic deformation characteristics of spring steel to adapt to different sizes of gravel. Combined with a turntable driving the screw to rotate and a gap adjustment structure for adjusting the clamping force of the connecting plate on the second disc through threaded engagement, it solves the problem of traditional devices lacking a pre-cleaning mechanism, which leads to gravel affecting the compaction quality. This achieves efficient collection and flexible discharge of large-diameter gravel.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0023] Please see Figures 1-8 This invention provides a technical solution: an earth and rock slope compaction device, including a roller body 1, a compaction roller 101 movably installed at the bottom of the roller body 1, the compaction roller 101 being used to directly compact the earth and rock slope, a wetting component 4 being provided at one end of the roller body 1, the wetting component 4 being used to control water and other functions, the wetting component 4 including a support frame 401 fixedly connected to the roller body 1, the support frame 401 providing fixed support for components such as a water tank 3 and a dripping component 411, a limiting block 2 being fixedly installed at the top of the support frame 401, the limiting block 2 having an arc-shaped groove at the top, the water tank 3 being fixedly installed in the arc-shaped groove at the top of the limiting block 2, the water tank 3 being used to store the water resources required for compaction operations, providing a water source for subsequent water spraying to moisten the soil and form a water film.

[0024] The top of the support frame 401 has an inlet 402 communicating with the inner cavity of the water tank 3, providing a channel for water to be transported from the water tank 3 to the storage tank 403. The lower interior of the support frame 401 has a storage tank 403 communicating with the inlet 402. The storage tank 403 is used to temporarily store water transported from the water tank 3, serving to buffer and evenly distribute the water flow. Multiple first drain holes 4011 are equidistantly arranged at the bottom of the storage tank 403, providing a transport channel for the water flow. The multiple equidistant first drain holes 4011 can achieve even distribution of the water flow. Each of the multiple first drain holes 4011 is equipped with a dripping component 411, which controls the output state of the water flow, achieving droplet-shaped transport and preventing excessive water flow. One end of the support frame 401 is arc-shaped, and a drainage groove 404 is located below the arc-shaped surface at one end of the support frame 401. The arc-shaped structure allows one end of the support frame 401 to fit against the lower outer surface of the roller 101, ensuring the adhesion of the water film formation. The drainage trough 404 guides the water transported by the storage tank 403 to the lower outer surface of the roller 101, ensuring the stable formation of the water film. The dripping assembly 411 includes a sleeve 4115 set inside the first drain hole 4011. The sleeve 4115 is used to limit the water flow and control the flow of water. A blocking block 4116 is set at the bottom of the sleeve 4115 to control the flow of water. The blocking block 4116 can control the flow of water through the first drain hole 4011, realizing the on-demand output of water and avoiding excessive water flow that would cause the soil to become too wet. Multiple guide grooves 4117 are circumferentially opened on the outer side of the blocking block 4116. The guide grooves 4117 are used to guide the water flow, so that the water flow forms a uniform dripping effect at the blocking block 4116, ensuring the uniformity of soil wetting and reducing water waste.

[0025] Water from the water tank 3 is dispersed and transported to the bottom of the support frame 401 during the movement of the roller 101 through the first drainage holes 4011 equidistantly opened at the bottom of the support frame 401. This pre-wets the soil to be compacted by the roller 101, improves the cohesion between soil particles, and thus enhances the compaction density and effect. Through the arc-shaped structure at one end of the support frame 401, one end of the support frame 401 is attached to the lower outer surface of the roller 101. Under the action of the drainage groove 404, a water film is formed below the outer surface of the roller 101, reducing the friction coefficient between the roller 101 and the soil, reducing soil adhesion, and ensuring smooth operation of the roller 101. Through the blocking block 4116 and the guide groove 4117 in the dripping component 411, the water flow forms a dripping effect at the conveying end, avoiding concentrated water flow that washes away the soil and causes local over-wetting or loss, thus balancing the wetting effect and water resource utilization rate.

[0026] The top of the support frame 401 is fixedly connected to one end of the roller body 1. A transverse groove 4010 is provided on one side of the support frame 401. A sliding plate 405 is slidably connected in the transverse groove 4010. The transverse groove 4010 provides sliding guidance for the sliding plate 405, ensuring that the sliding plate 405 moves back and forth in a fixed direction. The bottom of the sliding plate 405 is slidably connected to the top of the liquid storage tank 403. A squeezing plate 406 is fixedly connected to the top of the sliding plate 405. The squeezing plate 406 at the top of the sliding plate 405 can control the opening and closing of the opening at the top of the liquid storage tank 403 by sliding, thereby controlling the flow rate of water entering the liquid storage tank 403. Right-angle plates 407 are symmetrically and movably inserted through the middle of one side of the support frame 401. The ends of the two right-angle plates 407 are fixedly connected to the second connecting rods 408. The right-angle plates 407 are the second connecting rods. 408 provides installation support. The second connecting rod 408 is used to transmit the force between the right angle plate 407 and the limiting plate 410. The outer peripheral surfaces of the two second connecting rods 408 are fitted with first compression springs 409, which abut against the right angle plate 407 and the support frame 401 respectively. The first compression springs 409 use elastic restoring force to keep the limiting plate 410 in contact with the water inlet 402, thereby achieving the normally closed control of the water inlet 402. One end of the two second connecting rods 408 is fixedly connected to the limiting plate 410, which is movably inserted into the support frame 401. The upper surface of the limiting plate 410 is in contact with one end of the water inlet 402. By contacting and separating from the water inlet 402, the opening and closing of the water inlet 402 is controlled, thereby realizing the start and stop control of water supply from the water tank 3 to the storage tank 403.

[0027] The dripping assembly 411 also includes a vertical rod 4112 that movably passes through the sleeve 4115. A squeezing head 4110, which movably engages with the first leak hole 4011, is fixedly connected to the top of the vertical rod 4112. The vertical rod 4112 connects the squeezing head 4110 and the blocking block 4116, enabling synchronous linkage between the two. The top of the squeezing head 4110 is hemispherical, and this hemispherical structure facilitates engagement with the inclined surface at the bottom of the sliding plate 405. The squeezing head 4110 moves up and down through the squeezing action of the sliding plate 405. Multiple second leak holes 4111 are annularly formed on the top of the squeezing head 4110. These second leak holes 4111 guide the water flow from the first leak hole 4011 to the bottom of the squeezing head 4110. To ensure smooth water flow to the sleeve 4115, a horizontal plate 4113 is fixedly inserted through the outside of the vertical rod 4112. The horizontal plate 4113 is located inside the first leakage hole 4011 and its end is fixedly connected to the support frame 401. The horizontal plate 4113 provides sliding support and limit for the vertical rod 4112, ensuring that the vertical rod 4112 moves axially. A second compression spring 4114 is sleeved on the outer circumferential surface of the vertical rod 4112, with its two ends abutting against the horizontal plate 4113 and the squeezing head 4110 respectively. The second compression spring 4114 uses elastic restoring force to cause the squeezing head 4110 to drive the blocking block 4116 to reset when there is no external squeezing force, thereby closing the water flow channel in the sleeve 4115 and realizing the normally closed control of the dripping component 411.

[0028] The bottom of the blocking block 4116 is hemispherical to prevent jamming when in contact with the rolling roller 101. The top of the blocking block 4116 is conical, which facilitates the dispersion of water flow and forms a uniform drip through the guide groove 4117. The diameter of the circular hole in the center of the sleeve 4115 is larger than that of the vertical rod 4112 but smaller than that of the blocking block 4116. The size design of the central circular hole of the sleeve 4115 ensures smooth sliding of the vertical rod 4112 and reliably closes the water flow channel through cooperation with the blocking block 4116 to prevent leakage. The bottom sides of the slide plate 405 have inwardly sloping surfaces. The sloping structure facilitates the fit with the hemispherical surface of the extrusion head 4110. The sliding of the slide plate 405 achieves stable extrusion of the extrusion head 4110, thereby controlling the opening of the dripping component 411. One side of the extrusion plate 406 has an arc surface for auxiliary liquid dispensing. The arc surface design of the extrusion plate 406 can reduce the flow resistance of water and guide the water in the water tank 3 to smoothly enter the liquid storage tank 403 through the water inlet 402, avoiding splashing caused by the high-speed vertical drop of water. A vertical plate 412 is fixedly installed on one side of the bottom of the support frame 401. The vertical plate 412 is used to prevent water from drifting to non-working areas and at the same time provides an installation position for the cleaning component 5.

[0029] A drive shaft 102 is provided at one end of the roller 101. A first disc 103 is fixedly connected to the end of the drive shaft 102. The drive shaft 102 provides power transmission for the rotation of the roller 101 and drives the first disc 103 to rotate synchronously. A first connecting rod 104 is hinged to the outer surface of the first disc 103. The first disc 103 converts the rotation of the roller 101 into the reciprocating movement of the first connecting rod 104. One end of the first connecting rod 104 is hinged to the slide plate 405. The first connecting rod 104 converts the swing motion into the reciprocating sliding of the slide plate 405 through the hinge relationship, realizing the linkage control of the rotation of the slide plate 405 and the roller 101. This allows the opening of the dripping component 411 to be synchronized with the rotation of the roller 101, realizing on-demand water spraying and improving the automation level and operation coordination of the device.

[0030] A cleaning component 5 is provided at one end of the support frame 401. The cleaning component 5 is used to remove some large pieces of gravel in the front area to ensure the subsequent compaction effect of the roller 101. The cleaning component 5 includes a fixing block 501. The end of the fixing block 501 is fixedly connected to one side of the support frame 401. A crossbar 502 is movably passed through the fixing block 501. The fixing block 501 provides installation support for the crossbar 502, realizing the fixed connection between the cleaning component 5 and the support frame 401. The crossbar 502 can slide along the fixing block 501 to adjust the cleaning component. The distance between component 5 and the roller 101 is such that connecting arms 503 are fixedly connected to the outer surfaces of both ends of the crossbar 502. A horizontal shaft 504 is fixedly passed through one end of each connecting arm 503. Two second discs 505 are fixedly passed through the side end of the horizontal shaft 504. The connecting arms 503 connect the crossbar 502 and the horizontal shaft 504 to achieve the installation and fixation of the cleaning components. The horizontal shaft 504 provides an installation shaft for the second discs 505, ensuring the stable rotation of the second discs 505. The inner circumferential surfaces of the two second discs 505 are fixedly mounted with annular spacing. Multiple spring steels 506 rotate along with the second disc 505 as it rotates. When encountering gravel, the gaps between the spring steels 506 are expanded after being compressed, allowing the gravel to be collected into the cavity formed by the spring steels 506. (It should be noted that the spring steels 506 adopt a cylindrical strip structure, which can produce stable elastic deformation after compression and will not produce permanent deformation.) A connecting plate 507 is movably inserted through one end of the horizontal shaft 504, and one side of the connecting plate 507 is flush with the second disc 505. One end of the connecting plate 507 is fitted with a screw 508, which is rotatably connected to the other end of the connecting plate 507. The screw 508 is threadedly connected to the connecting arm 503. A turntable 509 is fixedly installed on one end of the connecting arm 503. By rotating the screw 508, which is threadedly engaged with the connecting arm 503, the clamping force of the connecting plate 507 on the second disc 505 can be adjusted, thereby adjusting the gap between the spring steels 506, so as to discharge the collected gravel. The turntable 509 facilitates manual rotation of the screw 508, improving the ease of operation.

[0031] It should be noted that the top of the roller body 1 is equipped with an engine for driving the compaction roller 101 to move, and an auxiliary roller is installed at the other end of the roller body 1. The above structures are existing devices and will not be described in detail here.

[0032] It should be further explained that round holes are provided at both ends of the top of the main body 1 of the road roller to facilitate the fixing of the winch. In the process of compacting earth and rock with a large slope, the winch auxiliary equipment is added at the top of the slope for compaction.

[0033] The workflow of this invention: The engine of the main body 1 of the road roller serves as the core power source, employing a high-power diesel engine specifically designed for engineering applications. The engine transmits power to the bearings of the compaction roller 101 via a planetary gearbox and universal joint drive shaft, driving the roller 101 to rotate clockwise. The compaction roller 101 features a double-layer hollow structure; the outer layer is made of a high-hardness, wear-resistant alloy material, and its surface undergoes a textured rolling process. This increases the contact friction with the soil and creates regular patterns during compaction to enhance the adhesion of the slope surface, ensuring effective compaction of earth and rock slopes. (It should be noted that the above-mentioned devices are all existing equipment, and the control devices are all existing systems; details will not be elaborated further.)

[0034] First, the engine of the road roller body 1 drives the roller 101 to rotate for compaction. At the same time, the roller 101 drives the drive shaft 102 at one end to rotate synchronously. The drive shaft 102 converts the rotational motion into the reciprocating swing of the first connecting rod 104 through the first disc 103, which in turn pulls the slide plate 405 to slide back and forth along the transverse groove 4010, so as to realize the synchronous linkage between the wet assembly 4 and the roller 101.

[0035] Precise water control and water flow distribution: In the initial state, the elastic restoring force of the first compression spring 409 causes the limiting plate 410 to fit against the water inlet 402, keeping the water inlet 402 normally closed.

[0036] When the slide plate 405 slides, the extrusion plate 406 at its top pushes the right-angle plate 407, which in turn drives the limiting plate 410 to disengage from the water inlet 402 via the second connecting rod 408. The water in the water tank 3 flows into the storage tank 403 through the water inlet 402. The arc design of the extrusion plate 406 guides the water flow to flow smoothly into the storage tank 403, avoiding splashing and evenly distributing the water flow to the first drain holes 4011 at equal intervals at the bottom, thus ensuring uniform wetting in the future.

[0037] During the process of sliding, the bottom inclined surface of the slide plate 405 squeezes the squeezing head 4110 of the dripping component 411. The hemispherical design ensures stable squeezing. The squeezing head 4110 drives the blocking block 4116 to move down through the vertical rod 4112, opening the water flow channel of the sleeve 4115. The water in the liquid storage tank 403 flows into the sleeve 4115 through the first leakage hole 4011 and the second leakage hole 4111 of the squeezing head 4110. Then, it forms uniform water droplets through the guide groove 4117 of the blocking block 4116 and drips onto the soil surface in front of the compaction roller 101, achieving precise pre-wetting before compaction and improving the cohesion of soil particles and the compaction effect. It should be noted that (when the slide plate 405 moves horizontally, it will drive the squeezing head 4110 to rise and fall, so that the water droplets at the bottom drip onto the soil surface in an indirect manner, thereby preventing the dripping water from being too concentrated, causing the local area of ​​soil to be too wet, the soil to be too sticky, and it to easily stick to the surface of the roller).

[0038] Meanwhile, some of the water in the storage tank 403 is discharged through the drainage tank 404. Because the arc surface of one end of the support frame 401 is in contact with the lower part of the outer surface of the rolling roller 101, the water flow forms a stable water film at the bottom of the rolling roller 101, which reduces the friction coefficient between the roller surface and the soil and reduces soil adhesion.

[0039] When there is no external pressure, the second compression spring 4114 drives the compression head 4110 and the blocking block 4116 to reset, close the water flow channel, achieve indirect waterproofing, avoid excessive water output, and avoid waste of water resources.

[0040] Finally, the cleaning component 5 at one end of the support frame 401 moves synchronously with the road roller. The second disc 505 drives the ring-shaped spring steel 506 to rotate. When encountering large pieces of gravel, the spring steel 506 is squeezed and undergoes elastic deformation, and the gap expands, collecting the gravel into the cavity formed by the spring steel 506, thus preventing the gravel from affecting the compaction effect.

[0041] Rotating the turntable 509 drives the screw 508 to rotate. The screw 508 and the connecting arm 503 are threaded together to adjust the clamping force of the connecting plate 507 on the second disc 505, thereby adjusting the gap between the spring steels 506, which facilitates the discharge of collected gravel and ensures the continuous effectiveness of the cleaning operation.
