[0002] In the existing technology, land compaction at some construction sites with limited bearing capacity is often achieved by using an excavator equipped with a rammer. In order to ensure the final tamping effect, the contact surface of the vibrating rammer with the ground is often a complete plane, which places high demands on the compacted soil quality. Moreover, for the hard materials in the soil to be broken, not only long-term vibration crushing is required, but the crushing effect is also average, and manual crushing is often required, which is time-consuming and labor-intensive. Summary of the invention

[0003] The object of the present invention is to overcome the above-mentioned shortcomings and provide a vibratory rammer for an excavator, which has the functions of switching between soil compaction pretreatment and crushing and compaction, has good compaction effect and simple structure.

[0004] To achieve the above purpose, the technical solution of the present invention is: a vibrating rammer for excavators. The rammer includes a contact shell, a connecting member, an ejection unit, a connecting plate and a driving member. The connecting member is arranged at the top of the contact shell and is detachably connected to the excavator. The bottom of the contact shell is provided with a plurality of openings, and a plurality of ejection units are arranged one by one at the openings. The ejection unit includes a support rod, a left swing plate and a right swing plate. The left swing plate and the right swing plate are relatively arranged in the opening. One end of the left and right swing plates are meshed with each other in a concave-convex shape and a rotating rod is longitudinally penetrated at the overlapping position of the two. The other ends of the left and right swing plates are both rotatably connected to the opening. The support rod is arranged above the meshing part of the left and right swing plates and is connected to the connecting plate. The connecting plate is connected to the driving member. The driving member is connected to the top of the contact shell. When working, the driving member prompts the support rod to move downward until the meshing part of the left and right swing plates is ejected from the bottom of the opening.

[0005] Furthermore, the other ends of the left and right swing plates are penetrated by sliding channels, and the left and right sides of the opening are provided with limit rods, and the limit rods pass through the sliding channels to realize the rotational connection between the left and right swing plates and the opening; the ejection unit also includes a reset rod, a slide seat and a clamping unit, and the slide seat is sleeved on the support rod, and the two reset rods have one end respectively connected to the left and right sides of the slide seat for rotation, and the other ends of the two reset rods are respectively connected to the left and right swing plates for rotation, and the clamping unit is arranged in the support rod, and the clamping unit can be movably connected to the slide seat; after use, the support rod is raised to clamp the clamping unit with the slide seat, and then the support rod is lowered to realize the reset of the position of the left and right swing plates.

[0006] Furthermore, the clamping unit includes a triangular plate and a telescopic motor, the telescopic motor is arranged in the support rod, at least two triangular plates are arranged in the support rod and each has a corner extending from the support rod, and the telescopic motor is connected to the triangular plate and controls its entry and exit in the support rod.

[0007] Furthermore, one end of the left and right swing plates are both comb-tooth-shaped concave-convex structures, and the rotating rod is located in the middle of the concave-convex structure; when being ejected, the left and right swing plates are in an X shape.

[0008] Furthermore, the ramming machine also includes a counterweight wheel, two of which are respectively arranged on the left and right sides of the bottom of the contact shell, and the left and right sides of the counterweight wheel are rotatably connected to a telescopic rod, and the counterweight wheel is connected to the contact shell through the telescopic rod. During the descending process of the contact shell, the counterweight wheel first contacts the ground, and then as the contact shell contacts the ground, the counterweight wheel retracts into the contact shell under the support of the ground.

[0009] Furthermore, the bottom of the contact shell is symmetrically provided with inclined surfaces on the left and right sides, and the counterweight wheel is arranged in the inclined surfaces. The inclined surfaces are controlled to move parallel to the ground so that the counterweight wheel can roll over the ground and rotate.

[0010] Furthermore, a plurality of convex portions are equidistantly arranged on the counterweight wheel.

[0011] Furthermore, observation holes are provided on both the front and rear sides of the contact shell.

[0013] 1. The present invention provides an ejection unit that can extend and retract in the contact shell, and provides left and right swing plates that are meshed and rotatably connected, so as to realize the formation of a sharp portion at the bottom of the contact shell without destroying the flat bottom of the contact shell, thereby realizing the switching of the tamping and leveling functions of the tamping machine. Multiple ejection units increase the pressure between the tamping machine plane and the hard material. The left and right swing plates are supported by the support rods to ensure the crushing strength and power of the left and right swing plates, thereby extending their service life. When in use, crushing pretreatment can be carried out according to the ground conditions in different areas, thereby improving the leveling effect and providing better flexibility.

[0014] 2. The present invention connects the left and right swing plates and the support rod by setting a reset rod and a slide seat, and increases the resistance to the swing of the left and right swing plates when they are pushed open, making the swing more stable; the left and right swing plates are reset by setting a clamping unit to cooperate with the multiple movements of the support rod, which is not only simple in structure, but also more stable in the triangular structure formed by the swing plate, the reset rod and the support rod, which can better ensure the tamping strength of the swing plate during tamping. By setting a counterweight wheel, in the process of vibrating and tamping the contact shell up and down, it contacts the ground in advance to determine the tamping position, thereby increasing the positioning effect of the vibration tamping, and at the same time increasing the function of the tamping machine to change the angle of the contact shell before and after tamping so that the counterweight wheel contacts the ground first to remove excess bumps, thereby increasing the use function of the tamping machine.

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but are not used to limit the present invention.

[0039] Reference Figure 1-6 The present invention provides a technical solution: a vibrating rammer for an excavator.

[0040] The vibration rammer comprises a contact shell 1 , a connecting member 2 , an ejection unit 3 , a connecting plate 4 , a driving member 5 and a counterweight wheel 6 .

[0041] The front and rear sides of the contact housing 1 are provided with observation holes 14 to facilitate the balance of the internal air and maintenance. The connecting member 2 is arranged on the top of the contact housing 1 and is detachably connected to the excavator. It can be assembled on the excavator with a base having a vibration function, or it can be assembled on the breaker of the excavator through the existing connection structure.

[0042] The contact shell 1 is used for contacting with the ground during the compaction process, and a plurality of openings 11 are provided at the bottom thereof, and a plurality of ejection units 3 are arranged one by one at the openings 11 .

[0043] The ejection unit 3 is used to change the state of the bottom of the contact housing 1. Specifically, the ejection unit 3 includes a support rod 31, a left swing plate 32, a right swing plate 33, a reset rod 35, a slide seat 36 and a clamping unit 37. The left swing plate 32 and the right swing plate 33 are arranged in the opening 11 relative to each other. One end of the left and right swing plates are meshed with each other in a concave-convex shape, and a rotating rod 34 is longitudinally penetrated at the overlapping position of the two. The support rod 31 is arranged above the meshing part of the left and right swing plates and connected to the connecting plate 4. The connecting plate 4 is connected to the driving member 5, and the driving member 5 is connected to the top of the contact housing 1. When working, the driving member 5 prompts the support rod 31 to move downward until the meshing part of the left and right swing plates is ejected from the bottom of the opening 11.

[0044] Among them, in order to ensure that the left and right swing plates can make up for the defects of the opening 11 on the contact shell 1 and reduce the influence of the opening 11 on the compaction effect, one end of the left and right swing plates is a comb-shaped concave-convex structure. In order to increase the impact pressure of the ejection unit 3 on the bottom surface, the rotating rod 34 is located in the middle position of the concave-convex structure. When being ejected, the left and right swing plates will be in an X shape. In order to increase the swing stability of the left and right swing plates and ensure that they can be reset, the other ends of the left and right swing plates are penetrated by a sliding channel 321, and a limit rod 12 is provided on the left and right sides of the opening 11. The limit rod 12 passes through the sliding channel 321 to realize the movable rotation connection between the left and right swing plates and the opening 11. The slide 36 is sleeved on the support rod 31, and the two reset rods 35 have one end respectively connected to the left and right sides of the slide 36 for rotation, and the other ends of the two reset rods 35 are respectively connected to the left and right swing plates for rotation, and the clamping unit 37 is arranged in the support rod 31, and the clamping unit 37 is movably connected to the slide 36; after use, the support rod 31 is raised to make the clamping unit 37 clamped with the slide 36, and then the support rod 31 is lowered to realize the reset of the position of the left and right swing plates. Specifically, the clamping unit 37 includes a triangular plate 371 and a telescopic motor 372. The telescopic motor 372 is arranged in the support rod 31, and at least two triangular plates 371 are arranged in the support rod 31 and each has a corner extending from the support rod 31. The telescopic motor 372 is connected to the triangular plate 371 and controls it to enter and exit the support rod 31. At this time, the triangular plate 371 is used to abut against the inner circle of the slide 36 to realize the movable clamping with the slide 36.

[0045] Two weighted wheels 6 are respectively arranged on the left and right sides of the bottom of the contact housing 1, and the left and right sides of the weighted wheels 6 are rotatably connected with telescopic rods 7, and the outer ring of the telescopic rods 7 may be sleeved with springs. The weighted wheels 6 are connected to the contact housing 1 through the telescopic rods 7. During the descent of the contact housing 1, the weighted wheels 6 first contact the ground, and then as the contact housing 1 contacts the ground, the weighted wheels 6 are retracted into the contact housing 1 under the support of the ground.

[0046] Furthermore, in order to further level and compact the tamped ground, the bottom of the contact housing 1 is provided with inclined surfaces 13 symmetrically on the left and right sides, and the weight wheel 6 is arranged in the inclined surface 13. When the weight wheel 6 is retracted in the contact housing 1, part of the structure of the weight wheel 6 protrudes from the inclined surface, and the inclined surface 13 is controlled to move parallel to the ground so that the weight wheel 6 can roll the ground and rotate. Optionally, a plurality of convex portions 61 are equidistantly arranged on the weight wheel 6 to increase the pre-treatment rolling function of the weight wheel 6, and the weight wheels 6 on the left and right sides of the contact housing 1 can have different structures.

[0047] Working principle: When in use, the contact housing 1 vibrates up and down on the left and right sides of the excavator. After each rise, the counterweight wheel 6 will remain on the ground to mark and locate the compacted position. When hard soil blocks are still found to be crushed after compacting the ground and loosening the soil, the driving member 5 can be started to move the support rod 31 downward, so that the left and right swing plates extend out of the bottom of the contact housing 1 in an X-shaped protrusion to crush the soil blocks, reducing the requirements for the excavation vibration frequency. When the crushing operation is not needed, the support rod 31 can be moved upward to connect the slide 36 with the clamping unit 37, and then the support rod 31 can be moved downward to drive the left and right swing plates to reset.
