Abstract
Description
Technical Field
[0001] This utility model relates to the field of shovel technology, and in particular to a shovel device with a conveniently switchable blade head. Background Technology
[0002] In the production of photovoltaic conductive silver paste, a three-roll mill is required for the dispersion process. Before the pre-prepared paste is fed into the mill, it needs to be initially stirred and mixed with a hard material. When the paste is fed into the mill for dispersion, the fluid-like paste will adhere to the mill rollers. At this point, a plastic scraper with low rigidity is needed to re-feed the paste adhering to the rollers, resulting in better overall dispersion. After stirring and mixing, a softer steel scraper is needed to clean the paste from the gaps in the mill rollers without scratching them.
[0003] This process requires three different models of shovels. Frequent switching not only wastes time but also makes the operator flustered, leading to production accidents. Utility Model Content

[0038] like Figures 1 to 6 As shown, this embodiment provides a shovel device with easily switchable blades, including a mounting frame 10, a rotating block 20, a connecting block 30, and multiple blades 40, each corresponding to different functional requirements. The mounting frame 10 has a groove 11, and the rotating block 20 is rotatably mounted in the groove 11. Multiple blades 40 are vertically mounted on the end face of the rotating block 20 facing outwards from the groove 11. When a blade 40 needs to be changed according to the usage scenario, the rotating block 20 is rotated to the working position. The rotating block 20 has multiple first positioning holes 21, and the mounting frame 10 has second positioning holes 14. The connecting block 30 passes through the first positioning holes 21 and the second positioning holes 14, keeping the rotating block 20 and the mounting frame 10 relatively fixed. After the blade 40 rotates to its position, the connecting block 30 holds the rotating block 20 and the mounting frame 10 in place, thus maintaining the blade 40 in the working position.
[0039] The shovel device with convenient blade switching provided in this embodiment integrates multiple blades 40 on the rotating block 20, avoiding clutter caused by multiple blades 40 being placed at the work site, thereby preventing safety accidents. When it is necessary to change the blade 40 during use, the blade 40 can be quickly switched by rotating the rotating block 20, making blade switching convenient.
[0040] Specifically, such as Figure 1 and Figure 4 As shown, the rotating block 20 has multiple mounting holes 22 on its end face facing the outside of the groove 11. The cutting tool 40 is installed in the mounting holes 22. The multiple mounting holes 22 are symmetrically distributed on the rotating block 20, so that the multiple cutting tools 40 are symmetrically distributed on the rotating block 20. The distribution of the cutting tools 40 is relatively uniform and reasonable, and mutual interference is avoided when using each cutting tool 40.
[0041] like Figure 1 and Figure 3 As shown, the cutting tool 40 includes a cutting head 42 and a mounting portion 41. The cutting head 42 is mounted on the mounting portion 41, and the cutting tool 40 is mounted in the mounting hole 22 through the mounting portion 41. A portion of the mounting portion 41 extends beyond the mounting hole 22. When the cutting tool 40 needs to be replaced, the connector 30 is pulled out, and the cutting tool 40 and the rotating block 20 can be rotated by moving the portion of the mounting portion 41 extending beyond the mounting hole 22. This prevents accidental injury to the user when moving the cutting tool 40.
[0042] Meanwhile, the mounting part 41 is detachably installed in the mounting hole 22, allowing the tool 40 to be removed from the rotating block 20, making the device more flexible in use. The tool 40 required for the process can be selected and installed on the rotating block 20. The tool 40's detachable installation is achieved by using an interference fit between the mounting part 41 and the mounting hole 22.
[0043] Regarding the specific installation method of mounting bracket 10 and rotating block 20, such as Figure 1 and Figures 6 to 10As shown, the mounting bracket 10 includes a fixing bracket 12 and a fixing block 13. A groove 11 is formed on the front of the fixing bracket 12, and a connecting hole 15 is formed at the bottom of the groove 11. The fixing block 13 includes a base 131, an extension 132 located on the base 131, and a connecting part 133 located on the extension 132. The cross-sectional area of the base 131 is larger than the cross-sectional area of the extension 132. The connecting part 133 on the extension 132 of the fixing block 13 passes through the connecting hole 15 in the groove 11, fixing the fixing block 13 and the fixing bracket 12. A circular hole 23 is formed in the middle of the rotating block 20. The rotating block 20 is located between the fixing block 13 and the fixing bracket 12, and the extension 132 of the fixing block 13 passes through the circular hole 23. The rotating block 20 is limited by the base 131 of the fixing block 13 and the bottom of the groove 11 of the fixing bracket 12, so that the rotating block 20 can only rotate between the fixing block 13 and the fixing bracket 12 and cannot move in other directions.
[0044] Furthermore, the fixing block 13 and the fixing frame 12 are detachably connected, and the extension 132 of the fixing block 13 is interference-fitted with the connecting hole 15 of the fixing frame 12. When the fixing block 13 and the fixing frame 12 are disassembled, the rotating block 20 between the fixing block 13 and the fixing frame 12 is also removed, so that the entire device can be disassembled and assembled, which facilitates mass production and transportation in the factory, and can be assembled when needed.
[0045] like Figure 4 and Figure 6 As shown, the rotating block 20 rotates around the axis of the circular hole 23. The first positioning hole 21 is formed on the side wall of the rotating block 20, and the second positioning hole 14 is formed on the side wall of the fixed block 13. In this way, during use, the user can keep the second positioning hole 14 of the fixed block 13 in front of them, which makes it more convenient to disassemble and install the connector 30.
[0046] Furthermore, such as Figure 3 and Figure 5 As shown, to facilitate faster and more convenient disassembly and installation of the connector 30 during tool switching 40, the second positioning hole 14 has a deformation portion 211. The deformation portion 211 is the part of the second positioning hole 14 closer to the connecting hole 15, and its cross-sectional area gradually decreases as it approaches the connecting hole 15. The connector block 30 has two opposing ends, and its cross-sectional area gradually decreases as it extends from one end to the other. Thus, when the connector 30 needs to be inserted into the second positioning hole 14, because the first part of the connector block 30 inserted has a smaller cross-sectional area, it is easier to align the end of the connector block 30 with the second positioning hole 14 and insert it into the second positioning hole 14, ultimately fitting with the deformation portion 211 of the second positioning hole 14, making tool switching 40 more convenient.
[0047] Furthermore, such as Figure 1 and Figure 3 As shown, the mounting bracket 12 is also equipped with a handle 50, which is fixedly connected to the back of the mounting bracket 12 and is positioned between the connecting hole 15 of the mounting bracket 12 and the edge of the back of the mounting bracket 12. Since the cutter 40 is not located at the center of the rotating block 20, the handle 50 and the cutter 40 are at the same height. When the roller mill is cleaning the slurry, the relative position of the cutter 40 and the roller mill can be adjusted by moving the handle 50 and thus the entire moving device. Because the handle 50 and the cutter 40 are at the same height, the position of the cutter 40 can be adjusted more precisely.
[0048] In summary, the shovel device with easily switchable blades provided in this embodiment can integrate multiple different blades 40 together, avoiding the safety risks caused by the clutter on site due to preparing multiple blades 40. Moreover, when it is necessary to change the blade 40 during use, the rotating block 20 can be driven to rotate on the mounting frame 10 by rotating the mounting part 41 of the blade 40, which can quickly switch the blade 40, making it convenient and efficient to use.
[0049] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
