Description

Technical Field

[0001] This utility model relates to the field of construction equipment, specifically to a vibratory compaction plate of a plate vibratory compactor. Background Technology

[0002] A plate compactor is a device used for compacting and vibrating the surface layer of a foundation. The compaction plate is the working end of the plate compactor. A common plate compactor consists of a rectangular plate body with a ring of plates welded to the upper edge of the plate body. A connecting seat is fixedly connected to the upper surface of the plate body, located between the ring of plates. The connecting seat is used to connect to the output end of the vibrating motor of the plate compactor. When the plate compactor is working, the lower surface of the plate body is in contact with the foundation soil surface. The vibrating motor drives the connecting seat and the plate body to vibrate, and the plate body transmits the vibration to the foundation, thereby compacting the soil.

[0003] Because the slab is thin, it is easily deformed when it is bumped, which adversely affects the flatness of the lower surface of the slab. This results in the slab not making proper contact with the soil surface, which in turn affects the compaction effect. Utility Model Content

[0004] The main purpose of this invention is to reduce the adverse effects on the vibration compaction effect.

[0005] To achieve the above objectives, this utility model provides a vibratory plate for a flat vibratory compactor, employing the following technical solution:

[0006] A vibratory plate for a flat vibratory compactor includes a connecting seat for connecting to the working end of a vibratory motor of the flat vibratory compactor. The vibratory plate is characterized in that it further includes a frustum, the upper surface area of ​​which is larger than the lower surface area of ​​which is greater, and the lower surface of which protrudes downward to form a boss.

[0007] A ring of plates is fixedly connected to the upper surface edge of the frustum, and a connecting seat is located between the ring of plates and fixedly connected to the upper surface of the connecting seat.

[0008] By adopting the above technical solution, when the plate compactor is working, the boss contacts the soil surface, and the vibration motor drives the connecting seat, the truncated pyramid and the boss to vibrate. The boss transmits the vibration to the soil, thereby compacting the soil. Due to the high strength of the boss and the truncated pyramid, the deformation of the truncated pyramid and the boss is reduced, allowing the boss to contact the soil surface better, thereby making the soil more uniformly stressed and reducing the adverse effects on the compaction effect.

[0009] Optionally, the frustum includes an upper frustum and a lower frustum, and a connecting component for connecting and fixing the two is provided between the upper frustum and the lower frustum.

[0010] By adopting the above technical solution, since the plate thickness of the connecting seat is relatively thin, the connecting seat is prone to deformation, which leads to the tilting of the truncated pyramid and the boss. The contact effect between the boss and the soil surface is poor. At this time, it is necessary to replace the connecting seat, truncated pyramid and boss. However, since the truncated pyramid is large in size and expensive, the overall cost of replacing the connecting seat, truncated pyramid and boss is high. In order to reduce costs, when replacing the connecting seat, the connecting component is operated to separate the upper platform and the lower platform. Then, the upper platform and the connecting seat are replaced. Finally, the connecting component is operated to connect and fix the new upper platform to the original lower platform, thereby achieving the goal of reducing costs.

[0011] Optionally, the connecting assembly includes a connecting rod fixedly connected to the lower surface of the upper platform. The connecting rod has a T-shaped cross-section. The upper surface of the lower platform has a connecting groove adapted to the connecting rod, and both ends of the connecting groove penetrate the corresponding side wall of the lower platform.

[0012] By adopting the above technical solution, the connecting rod and the connecting groove cooperate to make the upper platform and the lower platform detachably connected.

[0013] Optionally, the connecting assembly may also include a fastener that makes the connection between the connecting rod and the connecting groove more stable.

[0014] By adopting the above technical solution, the fastener makes the connection between the connecting rod and the connecting groove more stable, reducing the relative movement between the upper and lower platforms.

[0015] Optionally, the fixing component includes a fixing rod, one end of which is thickened to form an end head. The upper platform and the connecting rod are provided with through holes for the fixing rod to be inserted, and the lower platform is provided with a fixing groove that is adapted to the fixing rod.

[0016] By adopting the above technical solution, the fixing rod and fixing groove can limit the upper and lower platforms, thereby reducing the relative movement between the upper and lower platforms.

[0017] Optionally, the diameter of the through hole in the upper platform gradually increases from bottom to top.

[0018] By adopting the above technical solution, operators can more easily insert the fixing rod into the fixing groove.

[0019] Optionally, the fastener also includes bolts that correspond one-to-one with the end, the bolts passing through the enclosure and being inserted into the enclosure, and the end has threaded holes corresponding to the bolts.

[0020] By adopting the above technical solution, the bolt and end cap cooperate to limit the fixing rod, reducing the occurrence of the fixing rod disengaging from the lower and upper platforms on its own.

[0021] In summary, this application has at least one of the following technical advantages:

[0022] By setting up connecting seats, frustums, and bosses, the deformation of frustums and bosses is reduced due to their high strength, allowing the bosses to make better contact with the soil surface, thus making the soil more uniformly stressed and reducing the adverse effects on the compaction effect.

[0023] By setting up an upper platform, a lower platform, connecting rods, and connecting grooves, the goal of reducing costs can be achieved.

[0024] By setting fixed rods, ends, and fixed grooves, the relative movement between the upper and lower platforms is reduced. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] This application discloses a vibratory plate for a flat plate vibratory compactor. Example 1

[0033] Reference Figure 1It includes a frustum 1, the cross-sectional area of ​​the lower surface of the frustum 1 is smaller than the cross-sectional area of ​​the upper surface of the frustum 1, and the lower surface of the frustum 1 protrudes downward to form a boss 2; a connecting seat 3 is fixedly connected to the upper surface of the frustum 1, the connecting seat 3 is used to connect and fix to the output end of the vibration motor of the flat plate vibrator, and a ring of surrounding plates 4 is fixedly connected to the upper surface of the frustum 1, the surrounding plates 4 are distributed around the edge of the frustum 1, and the connecting seat 3 is located in the ring of surrounding plates 4.

[0034] When the plate compactor is working, the boss 2 contacts the soil surface. The vibration motor drives the frustum 1 and the boss 2 to vibrate through the connecting seat 3. The boss 2 transmits the vibration to the soil, thereby compacting the soil. During the process of the boss 2 compacting the soil, since the cross-sectional area of ​​the frustum 1 gradually increases from bottom to top, the boss 2 and the frustum 1 have great strength, which reduces the deformation of the frustum 1 and the boss 2. The lower surface of the boss 2 can also better contact and fit with the soil surface, so that the boss 2 can better transmit the vibration to the soil and reduce the adverse effects on the compaction effect.

[0035] The implementation principle of Embodiment 1 of this application is as follows: When the plate compactor is working, the boss 2 contacts the soil surface, the vibration motor of the plate compactor is started, and the boss 2 transmits the vibration to the soil. Example 2

[0036] Because the plate of connecting seat 3 is relatively thin, when connecting seat 3 deforms, it may cause the frustum 1 to tilt, resulting in uneven contact between the frustum and the soil surface. In this case, the vibratory compaction plate needs to be replaced. However, because the frustum 1 is large, the overall replacement cost is high. In order to save costs, based on embodiment 1, referring to... Figure 2 and Figure 3 In this embodiment, the frustum 1 includes an upper frustum 11 and a lower frustum 12. The upper frustum 11 and the lower frustum 12 are detachably connected. The connecting seat 3 and the surrounding plate 4 are fixed on the upper frustum 11. When the connecting seat 3 is deformed, the operator can separate the upper frustum 11 from the lower frustum 12 and then replace the upper frustum 11. The lower frustum 12 and the boss 2 can continue to be used, thereby achieving the purpose of saving costs.

[0037] Reference Figure 3 and Figure 4A connecting component 5 is provided between the upper platform 11 and the lower platform 12 to fix the upper platform 11 and the lower platform 12. The connecting component 5 includes a connecting rod 51 fixedly connected to the lower surface of the upper platform 11. The connecting rod 51 has a T-shaped cross section. In this embodiment, there are two connecting rods 51. In other embodiments, the number of connecting rods 51 can be one or more. When the number of connecting rods 51 is greater than one, all connecting rods 51 are parallel to each other. A connecting groove 121 adapted to the connecting rod 51 is opened on the upper surface of the lower platform 12. The connecting groove 121 penetrates the two opposite side walls of the lower platform 12. The connecting rod 51 is inserted into the connecting groove 121. The connecting rod 51 and the connecting groove 121 cooperate to make the upper platform 11 and the lower platform 12 detachably connected.

[0038] The connecting assembly 5 also includes a fixing member 52 that better fits the connecting rod 51 with the connecting groove 121. The fixing member 52 includes a fixing rod 521 that corresponds one-to-one with the connecting rod 51. One end of the fixing rod 521 is thickened to form an end 522. The upper platform 11 and the connecting rod 51 have through holes for the fixing rod 521 to be inserted into. The lower platform 12 has a fixing groove 122 that is adapted to the fixing rod 521. When the upper platform 11 and the lower platform 12 are engaged, the through holes of both the upper platform 11 and the lower platform 12 are connected to the corresponding fixing grooves 122. The fixing rod 521 is inserted into the through holes of the upper platform 11 and the connecting rod 51, and the fixing rod 521 is inserted into the fixing groove 122. The end 522 is in contact with the upper surface of the upper platform 11. In order to make it easier for the operator to insert the fixing rod 521 into the fixing groove 122, the diameter of the through hole of the upper platform 11 gradually increases from bottom to top.

[0039] Reference Figure 3 and Figure 4 The fastener 52 also includes bolts 523 that correspond one-to-one with the end 522. The bolts 523 pass through the surrounding plate 4 and slide into the surrounding plate 4. The end 522 has a threaded hole 5221 that is adapted to the bolts 523. The bolts 523 and the end 522 are threadedly engaged.

[0040] When connecting the upper platform 11 and the lower platform 12, the operator aligns the connecting rod 51 with the corresponding connecting groove 121, then moves the upper platform 11 and the lower platform 12 so that the connecting rod 51 is inserted into the connecting groove 121 until the corresponding side walls of the upper platform 11 and the lower platform 12 are flush. Then, the fixing rod 521 is inserted into the fixing groove 122 until the end 522 contacts the upper surface of the upper platform 11. At this time, the bolt 523 is moved and rotated until the bolt 523 engages with the threaded hole 5221. The fixing rod 521 and the fixing groove 122 engage to limit the upper platform 11 and the lower platform 12, reducing the relative movement between the upper platform 11 and the lower platform 12. The bolt 523 and the end 522 engage to limit the fixing rod 521, reducing the occurrence of the fixing rod 521 disengaging from the fixing groove 122.

[0041] When it is necessary to separate the upper platform 11 and the lower platform 12, the operator first rotates and moves the bolt 523 to separate the bolt 523 from the end 522. Then, the operator pulls the end 522 upward until the fixing rod 521 is separated from the upper platform 11. At this time, the operator moves the lower platform 12 to separate the lower platform 12 from the upper platform 11. Then, the operator replaces the upper platform 11 and the connecting seat 3. Finally, the operator fixes the upper platform 11 and the lower platform 12 in accordance with the above operation.

[0042] The implementation principle of Embodiment 2 of this application is as follows: When it is necessary to connect and fix the upper platform 11 and the lower platform 12, the operator aligns the connecting rod 51 with the connecting groove 121, moves the upper platform 11 and the lower platform 12 until the corresponding side walls of the upper platform 11 and the lower platform 12 are aligned, then inserts the fixing rod 521 into the corresponding fixing groove 122, and finally moves and rotates the bolt 523 so that the bolt 523 and the end head 522 are threadedly engaged; when it is necessary to replace the connecting seat 3, the operator rotates and moves the bolt 523 until the bolt 523 and the end head 522 are separated, then pulls out the fixing rod 521, and then moves the lower platform 12 so that the lower platform 12 is separated from the upper platform 11. At this time, the connecting seat 3 is removed and a new connecting seat 3 is installed. Finally, the upper platform 11 and the lower platform 12 are connected and fixed according to the above operation steps.

[0043] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
