Description

Technical Field

[0001] The present application relates to the technical field of compactors, and in particular to an earth compaction device for ecological restoration. Background Art

[0002] A compactor is a kind of engineering machinery, which is mainly used for compacting the surface of the soil and can reinforce the foundation in projects such as roads, dams, airport runways, and port terminals. It can crush, sink and compact the soil to make it more compact, and is often used in earthwork backfill construction for ecological restoration.

[0003] Hydraulic compactors are often used in earth backfill construction for ecological restoration. Their working principle is mainly to generate high-pressure hydraulic energy through a hydraulic pump, drive the hydraulic cylinder to perform telescopic movement, and then enable the compacting hammer to perform high-frequency, high-energy impact compaction on the ground.

[0004] The existing hydraulic compactor includes a fixed frame, a shell, a hydraulic cylinder and a compactor. The fixed frame is used in conjunction with a special carrier (such as an excavator). The fixed frame and the carrier are detachably connected, and the hydraulic compactor can be controlled by the carrier to be in a vertical position to the ground; the shell is slidably connected to the fixed frame, the hydraulic cylinder is installed inside the shell, and the compactor is installed at the bottom of the shell. The shell is driven to slide relative to the fixed frame by the telescopic movement of the hydraulic cylinder, thereby driving the compactor to impact and compact the ground.

[0005] However, both the fixing frame and the shell have clearance holes for the hydraulic pipes to pass through, so that during the storage, transportation and use of the hydraulic rammer, impurities such as dust and sand can easily enter the interior of the shell through the clearance holes, which may affect the normal use of the hydraulic cylinder and further affect the compaction efficiency and effect of the hydraulic rammer. Utility Model Content

[0006] The present application provides an earth compaction device for ecological restoration, which can effectively reduce the probability of impurities entering the interior of the shell and affecting the normal use of the compaction device, thereby effectively ensuring the compaction efficiency and effect of the compaction device.

[0016] Optionally, the fixed part, the movable part and the end of the shell away from the tamping hammer are all magnetic, and the movable part and the corresponding fixed part and the end of the shell away from the tamping hammer are all magnetically attracted to each other.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-4 This application is described in further detail.

[0039] The embodiment of the present application discloses an earthwork compaction device for ecological restoration, which is controlled by a dedicated vehicle (such as an excavator) to compact the soil after backfilling of the earthwork for ecological restoration. In this embodiment, since it is a common prior art to control the compaction device (i.e., a hydraulic compactor) by an excavator to compact the soil, it will not be described in detail here, and the dedicated vehicle is omitted in the drawings.

[0040] Reference Figure 1 and Figure 2 The compaction device includes a fixing frame 1, a housing 2, a hydraulic cylinder 3, a compaction hammer 4 and a dust shield 5. The fixing frame 1 is used to form a connection between the compaction device and a dedicated carrier; the interior of the housing 2 is used to install the hydraulic cylinder 3; the compaction hammer 4 is used to contact the ground to compact the soil; the hydraulic cylinder 3 is used to apply an impact force to the compaction hammer 4, and the compaction hammer 4 transmits the impact force to the ground to compact the soil.

[0041] The fixing frame 1 is a rectangular frame structure as a whole. One side of the fixing frame 1 has a connecting portion 11 near the bottom for a special carrier to connect with it. After the fixing frame 1 is connected to the special carrier, the special carrier can control the relative rotation of the fixing frame 1, thereby controlling the position state of the compaction equipment, making it easier for the carrier to transport and use the compaction equipment.

[0042] The shell 2 is a rectangular parallelepiped structure as a whole, and the shell 2 is interlaced with the fixing frame 1, and the length direction of the shell 2 is parallel to the length direction of the fixing frame 1. The shell 2 is slidably connected to the fixing frame 1, and the sliding direction of the shell 2 is parallel to its own length direction, and the length dimension of the shell 2 is greater than the length dimension of the fixing frame 1.

[0043] The housing 2 has a cavity 21 inside, and the hydraulic cylinder 3 is fixedly mounted on the housing 2 and located in the cavity 21. In this embodiment, since the hydraulic cylinder 3 in the compaction device is a common prior art, it is not described here in detail, and is only briefly shown in the drawings.

[0044] The tamping hammer 4 is fixedly mounted at the bottom of the housing 2. When the hydraulic cylinder 3 performs piston movement in a direction parallel to the length direction of the housing 2, it can repeatedly contact the tamping hammer 4 to exert impact force thereon, so that the tamping hammer 4 can exert impact force on the soil.

[0045] The hydraulic cylinder 3 is equipped with a plurality of hydraulic pipes, and the surface of the housing 2 and the surface of the fixing frame 1 are provided with a plurality of clearance openings 6 for the hydraulic pipes to pass through, and the clearance openings 6 on the housing 2 can make the cavity 21 communicate with the outside world, so that the two ends of the hydraulic pipe are connected to the hydraulic cylinder 3 and the dedicated vehicle respectively, so that the construction personnel can control the compaction equipment through the dedicated vehicle conveniently. In this embodiment, since the hydraulic pipes equipped with the hydraulic cylinder 3 are common prior art, and for the convenience of expression, the plurality of hydraulic pipes are omitted in the drawings.

[0046] The dust shielding device 5 is installed on the fixing frame 1 , and includes three dust shielding plates 51 . The three dust shielding plates 51 are all installed on the outside of the fixing frame 1 and are respectively located on three sides of the fixing frame 1 except the location of the connecting portion 11 .

[0047] The dust shield 51 is a square plate-shaped structure as a whole. A width side of the dust shield 51 is rotatably connected to the bottom of the corresponding side of the fixing frame 1. The rotation axis of the dust shield 51 is parallel to its own side length direction and perpendicular to the length direction of the fixing frame 1.

[0048] The dust shield 51 has limitations during its rotation relative to the fixing frame 1. When the dust shield 51 is rotated to the extreme position in the direction close to the fixing frame 1, the dust shield 51 can fit and abut against the end face of one side corresponding to the fixing frame 1. At this time, the square end face of the dust shield 51 is parallel to the length direction of the fixing frame 1, and the dust shield 51 can block the multiple clearance openings 6 on the surface of the corresponding side of the fixing frame 1; when the dust shield 51 is rotated to the extreme position in the direction away from the fixing frame 1, the square end face of the dust shield 51 is perpendicular to the length direction of the fixing frame 1, and the dust shield 51 can play a protective role on the side corresponding to the fixing frame 1 and on the side of the tamping hammer 4 close to the fixing frame 1.

[0049] Furthermore, in order to facilitate the dust shield 51 to maintain the current position state after rotating to the extreme position in the direction close to the fixing frame 1, it is preferred that the dust shield 51 and the fixing frame 1 are detachably connected.

[0050] Preferably, the position on the dust shield 51 that contacts the fixing frame 1 and the position on the fixing frame 1 that contacts the dust shield 51 are both magnetic and magnetically attracted to each other. At this time, when the dust shield 51 rotates to contact the fixing frame 1, the magnetic attraction force between the two can keep the dust shield 51 in the current position. In this embodiment, magnets with opposite magnetic poles are preferably fixedly mounted on the dust shield 51 and the fixing frame 1 respectively; in other embodiments, the dust shield 51 and the fixing frame 1 can also be detachably connected by means of bolt thread matching.

[0051] Reference Figure 2 and Figure 3 The dust blocking device 5 also includes three dust blocking components 52 , which are respectively installed on the sides of the three dust blocking plates 51 to further improve the dust blocking effect of the dust blocking device 5 .

[0052] The dust shield assembly 52 includes a fixing member 521 , a dust shield cover 522 and a movable member 523 .

[0053] The fixing member 521 is a rectangular plate-shaped structure as a whole, and one end of the fixing member 521 in the length direction is rotatably connected to a corner of the dust shield 51 away from its own rotation axis. The rotation axis of the fixing member 521 is perpendicular to the thickness direction of the dust shield 51 and parallel to a diagonal of the square end face of the dust shield 51.

[0054] The fixing part 521 has a limitation in its rotation relative to the dust shield plate 51. When the fixing part 521 rotates to the extreme position in the direction away from the rotation axis of the dust shield plate 51, the fixing part 521 is located on the side of the dust shield plate 51 away from its own rotation axis, and the length direction of the fixing part 521 is parallel to the rotation axis of the dust shield plate 51; when the fixing part 521 rotates to the extreme position in the direction close to the rotation axis of the dust shield plate 51, the fixing part 521 is located on the side of the dust shield plate 51 along the direction of its own rotation axis, and the length direction of the fixing part 521 is perpendicular to the rotation axis of the dust shield plate 51.

[0055] The dust cover 522 is a corrugated belt-like structure. The dust cover 522 can be folded and unfolded along its length direction according to needs, and a number of light-transmitting holes are evenly distributed on the dust cover 522. The aperture of the light-transmitting hole is smaller than the particle size of the dust particles on site, so that the dust cover 522 can have the effects of both light transmission and dust blocking. In this embodiment, due to the small size of the light-transmitting hole, the light-transmitting hole on the dust cover 522 is omitted in the drawings for ease of expression.

[0056] The movable part 523 is also a rectangular plate-shaped structure as a whole. The two ends of the dust cover 522 in the length direction are respectively fixedly connected to a length side of the fixed part 521 and a length side of the movable part 523, and the dust cover 522 is folded or unfolded according to the change of the distance between the movable part 523 and the fixed part 521.

[0057] The movable part 523 is detachably connected to the corresponding fixed part 521. When the movable part 523 is connected to the corresponding fixed part 521, the dust cover 522 is located between the movable part 523 and the corresponding fixed part 521 and is in a completely folded state. In this embodiment, the movable part 523 and the corresponding fixed part 521 are preferably magnetic and magnetically attracted to each other, that is, magnets with opposite magnetic poles are fixedly installed on the movable part 523 and the corresponding fixed part 521 respectively; in other embodiments, the movable part 523 and the corresponding fixed part 521 can also be detachably connected to each other by bolt thread matching.

[0058] Furthermore, preferably, there is also a detachable connection between the movable part 523 and the end of the shell 2 away from the tamping hammer 4. In this embodiment, it is also preferred that the movable part 523 and the side corresponding to the end of the shell 2 away from the tamping hammer 4 are both magnetic and the two are magnetically attracted, that is, magnets with opposite magnetic poles are fixedly installed on the movable part 523 and the side corresponding to the end of the shell 2 away from the tamping hammer 4; in other embodiments, the movable part 523 and the side corresponding to the end of the shell 2 away from the tamping hammer 4 can also be detachably connected by bolt thread matching.

[0059] Reference Figure 2 When the dust shield plate 51 is in a position to be abutted against the fixing frame 1 and the fixing member 521 is controlled to rotate to the side of the dust shield plate 51 away from its own rotation axis, the movable member 523 is controlled to separate from the corresponding fixing member 521 and connect with the side of the shell 2 away from the end of the tamping hammer 4. At this time, the dust cover 522 between the movable member 523 and the corresponding fixing member 521 will be unfolded, and the unfolded dust cover 522 can block the multiple clearance openings 6 corresponding to the surface of the shell 2 on the corresponding side of the shell 2, thereby further reducing the probability of impurities entering the cavity 21 through the clearance openings 6. In actual applications, if the hydraulic pipe needs to pass through the clearance opening 6 blocked by the northern dust cover 522, the hydraulic pipe can enter from the gap between the dust cover 522 and the shell 2, thereby meeting different installation requirements of the hydraulic pipe.

[0060] Reference Figure 3 and Figure 4When the dust shield plate 51 rotates to the extreme position in the direction away from the fixed frame 1 and the fixed frame is controlled to rotate to one side of the dust shield plate 51 along its own rotation axis, the movable part 523 is controlled to form a connection with one side of the adjacent dust shield plate 51. At this time, the dust shield cover 522 between the movable part 523 and the adjacent dust shield plate 51 will be unfolded, and the unfolded dust shield cover 522 can form a shield in the space above the tamping hammer 4 and between the adjacent dust shield plates 51, thereby effectively reducing the impact of dust generated during the tamping process.

[0061] At this time, light can shine through the multiple light-transmitting holes on the three unfolded dust shields 522 onto the soil around the tamping hammer 4, thereby making it convenient for construction workers to observe the compaction condition of the soil.

[0062] Furthermore, the movable member 523 is preferably detachably connected to the adjacent dust shield 51. In this embodiment, the movable member 523 and the adjacent dust shield 51 are preferably magnetic and magnetically attracted to each other, that is, magnets with opposite magnetic poles are fixedly mounted on the movable member 523 and the adjacent dust shield 51, respectively; in other embodiments, the movable member 523 and the adjacent dust shield 51 can also be detachably connected to each other by means of bolt thread engagement.

[0063] Furthermore, when the dust shield plate 51 rotates to the extreme position in the direction away from the fixing frame 1 and the fixing frame is controlled to rotate to one side of the dust shield plate 51 along its own rotation axis, the dust cover 522 between the two dust shield plates 51 on both sides of the connecting portion 11 will unfold and pass under the connecting portion 11. At this time, there is an empty space 7 between the dust cover 522 and the fixing frame 1.

[0064] In order to reduce the probability of dust affecting the structure in the cavity 21 through the empty space 7, the fixing frame 1 also has a filling plate 12 adapted to the empty space 7 on the side where the connecting portion 11 is located. The filling plate 12 is located on the side of the connecting portion 11 close to the tamping hammer 4 and can fill the above-mentioned empty space 7.

[0065] Furthermore, in order to improve the position stability of the dust cover 522 on one side of the above-mentioned filling plate 12 after being unfolded, thereby improving the dust-blocking effect of the dust cover 522, it is preferred that a detachable connection is formed between the dust cover 522 and the filling plate 12. In this embodiment, it is preferred that the side of the dust cover 522 close to the filling plate 12 and the side of the filling plate 12 away from the fixing frame 1 are both magnetic and the two are magnetically attracted to each other, that is, the side of the dust cover 522 close to the filling plate 12 and the side of the adjacent filling plate 12 away from the fixing frame 1 are respectively fixedly mounted with magnets with opposite magnetic poles; in other embodiments, the above-mentioned dust cover 522 and the filling plate 12 can also be detachably connected by means of bolt thread matching.

[0066] The implementation principle of an earthwork compaction device for ecological restoration in the embodiment of the present application is as follows:

[0067] When the compacting equipment needs to be stored or transported, the three dust shields 51 are controlled to rotate to a position against the fixing frame 1, and the movable parts 523 in the three dust shield assemblies 52 are detachably connected to the end of the shell 2 away from the compacting hammer 4, so that the three dust shields 51 and the three dust shield covers 522 can shield the shell 2 and the multiple clearance openings 6 on the fixing frame 1, thereby effectively reducing the probability of impurities entering the cavity 21 and affecting the normal operation of the compacting equipment;

[0068] When the compacting equipment is used, the three dust shield plates 51 are controlled to rotate to the extreme position in the direction away from the fixed frame 1, and the fixing parts 521 in the three dust shield assemblies 52 are rotated to the side of the corresponding dust shield plate 51, and the movable parts 523 are detachably connected to the adjacent dust shield plates 51, so that the three dust shield plates 51 and the three dust shield covers 522 can all play a protective effect above the compacting hammer 4, thereby effectively reducing the probability of dust generated during the compaction process affecting the normal operation of the compaction equipment.

[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
