DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This embodiment provides a cleaning device for excavation sites, mainly used to address the problem of soil adhering to the shovel head and being difficult to clean.

[0024] like Figure 1 As shown, it includes a shovel head 10 and a shovel handle 12 fixedly connected to the shovel head 10. Specifically, the shovel head 10 is horizontally arranged, and a vertically upward extending baffle 11 is fixedly provided at the tail of the shovel head 10. The shovel handle 12 is fixedly installed on the back side of the baffle 11.

[0025] It is worth noting that the shovel head 10 and the shovel handle 12 are located on both sides of the baffle 11. The shovel head 10 and the baffle 11 are formed by bending and forming, or the shovel head 10 and the baffle 11 are formed by forging.

[0026] When the shovel digs through damp soil, soil easily sticks to the shovel head 10. To clean the soil from the shovel head 10, in this embodiment, as follows: Figure 1 and Figure 3 As shown, the shovel head 10 is provided with a scraper 2, wherein the bottom wall of the scraper 2 abuts against the top wall of the shovel head 10, the scraper 2 is slidably connected to the shovel head 10, and a drive mechanism for pushing the scraper 2 to move is also included.

[0027] It is worth noting that when the shovel is not interfered with, the scraper 2 is close to the side of the baffle 11. At this time, the presence of the scraper 2 does not affect the digging of the soil by the shovel head 10. When it is necessary to clean the soil adhering to the shovel head 10, the drive mechanism pushes the scraper 2 to move away from the baffle 11, and the soil on the shovel head 10 is cleaned by the scraper 2.

[0028] To improve the stability of the scraper 2 during its movement, in this embodiment, as follows: Figure 2 and Figure 4 As shown, the scraper 2 has a buckle and a folded edge 21 on the bottom side that fastens inward to the shovel head 10, wherein the buckle and the folded edge 21 are slidably connected to the side wall of the shovel head 10.

[0029] With the above settings, when the scraper 2 is moving, the buckle and folded edge 21 hold the side wall of the shovel head 10, thereby improving the stability of the scraper 2's movement, preventing the scraper 2 from tilting during the soil pushing process, and improving the soil pushing effect.

[0030] In order to achieve the pushing action of scraper 2, in this embodiment, as follows: Figure 2 and Figure 3 As shown, the driving mechanism includes a driving ring 3 sleeved on the outside of the shovel handle 12. The inner wall of the driving ring 3 is slidably connected to the outer wall of the shovel handle 12. The driving ring 3 is fixedly connected to the scraper 2 through the push plate 22.

[0031] When it is necessary to clean the soil from the shovel head 10, the drive ring 3 is manually pushed, which in turn pushes the scraper 2 against the push plate 22, thereby pushing the soil to the outside of the shovel head 10.

[0032] To further improve the stability of the scraper 2 movement, in this embodiment, as follows: Figure 2 and Figure 3 As shown, the baffle 11 is provided with a clearance hole 111, wherein one end of the push plate 22 passes through the clearance hole 111 and is fixedly connected to the scraper 2, and the other end of the push plate 22 is fixedly connected to the drive ring 3, wherein the outer wall of the push plate 22 is slidably connected to the inner wall of the clearance hole 111.

[0033] It is worth noting that the push plate 22 is provided in two sets and located around the circumference of the shovel handle 12, which improves the stability of the scraper 2 during the pushing process.

[0034] After the soil on the shovel head 10 is cleared, in order to achieve automatic reset of the drive ring 3 and scraper 2, in this embodiment, as follows: Figure 2 and Figure 3 As shown, the shovel handle 12 is made of hollow steel tube. The side wall of the shovel handle 12 is provided with a sliding groove 121 arranged around the circumference of the shovel handle 12. A compression spring 5 is placed in the inner cavity of the shovel handle 12. The inner wall of the drive ring 3 is provided with a push post 31 that extends through the sliding groove 121 into the inner cavity of the shovel handle 12. The push post 31 is slidably connected to the side wall of the sliding groove 121. One end of the compression spring 5 abuts against the bottom wall of the inner cavity of the shovel handle 12, and the other end of the compression spring 5 abuts against the outer wall of the push post 31.

[0035] With the above settings, when the scraper 2 pushes the soil, the drive ring 3 drives the push column 31 to move towards the side of the shovel head 10 and compresses the compression spring 5. When the soil is cleared, the restriction on the drive ring 3 is released, and the compression spring 5 resets the scraper 2 and drive ring 3 through the push column 31.

[0036] Normally, when the drive ring 3 is located away from the shovel head 10, the slide groove 121 is easily exposed on the outside. When the shovel digs the soil, soil or silt can easily enter the inner cavity of the shovel handle 12 through the slide groove 121. When the inner cavity of the shovel handle 12 is filled with silt, the compression spring 5 cannot be compressed, affecting the use of the shovel. Therefore, in this embodiment, if...Figure 1 and Figure 3 As shown, the push plate 22 is located on both sides of the chute 121 and can block the chute 121 to prevent soil or silt from entering the inner cavity of the shovel handle 12.

[0037] Since the inner wall of the drive ring 3 is fixedly provided with a pusher post 31, and the pusher post 31 needs to be inserted into the inner cavity of the shovel handle 12 through the sliding groove 121, in this embodiment, in order to facilitate the installation of the pusher post 31 in the drive ring 3, in this embodiment, as follows: Figure 2 and Figure 4 As shown, the drive ring 3 is divided into two along the axial direction. The push post 31 is arranged radially along the drive ring 3 and divided into two ends. When the drive ring 3 is installed, the two parts of the drive ring 3 can be moved from both sides of the shovel handle 12 and the push post 31 can be inserted into the inner cavity of the shovel handle to form a complete ring. The outer wall of the drive ring 3 is also provided with a first threaded hole 301 extending into the inside of the push post 31. The first threaded hole 301 is internally threaded with a first bolt 61, thereby completing the assembly of the drive ring 3.

[0038] In order to fix the drive ring 3 to the push plate 22, in this embodiment, as follows: Figure 2 As shown, the push plate 22 is provided with a positioning screw hole 221 on the side near the drive ring 3, and the drive ring 3 is provided with a second threaded hole 302 arranged along the axial direction of the drive ring 3. The second threaded hole 302 is aligned with the positioning screw hole 221, and a second bolt 62 that is threadedly connected to the positioning screw hole 221 is installed in the second threaded hole 302. The drive ring 3 and the push plate 22 are fixed by the second bolt 62.

[0039] In this embodiment, as Figure 2 and Figure 3 As shown, the end of the shovel handle 12 is also threadedly connected to an end head 4, wherein the end head 4 is used to seal the opening at the end of the shovel handle 12. It is worth noting that the compression spring 5 mentioned above is installed from the opening at the end of the shovel handle 12.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
