[0033] Example 1
[0034] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides an electric heating scraper device for cleaning an arc-shaped stirrer, comprising:
[0035] A wooden handle 100 is provided with a push-button switch 101 on the outer wall of the wooden handle 100. A plug wire 102 is fixedly installed at the bottom of the wooden handle 100. A ceramic insulated heating mechanism 103 is fixedly installed at the top of the wooden handle 100. A knife holder 104 is fixedly installed at the end of the ceramic insulated heating mechanism 103 away from the wooden handle 100.
[0036] The disassembly and assembly unit 200 is located at the end of the knife holder 104 away from the ceramic insulated heating mechanism 103. The disassembly and assembly unit 200 includes a locking block 205 and a spring 203. Under the elastic action of the spring 203, the locking block 205 can be pushed so that the locking block 205 can engage with the scraper 211, thereby achieving the effect of quick disassembly and assembly of the scraper 211.
[0037] The protective unit 300 is placed outside the disassembly unit 200. The protective unit 300 includes a protective sleeve 302, which is used to protect the scraper 211 after use to prevent the operator from being burned by residual heat.
[0038] When using the device to clean asphalt, connect the plug 102 to the power supply. Under the constraint of the ceramic insulated heating mechanism 103, the scraper 211 can be heated. The operator holds the wooden handle 100 and turns on the button switch 101. The scraper 211 can then be used to clean the residual asphalt adhering to the mixer. Under the constraint of the disassembly unit 200, the scraper 211 can be replaced as needed to facilitate flexible cleaning. Under the constraint of the protection unit 300, the scraper 211 can be protected to prevent the operator from being burned by the residual heat of the scraper 211.
[0039] Example 2
[0040] Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows:
[0041] The disassembly and assembly unit 200 includes a vertical block 201 fixedly installed on the top surface of the blade holder 104. A slide rod 202 is slidably arranged inside the vertical block 201. A spring 203 is sleeved on the outer wall of the slide rod 202. A push plate 204 is fixedly installed at the end of the slide rod 202. A locking block 205 is fixedly installed on the side of the push plate 204 away from the slide rod 202. A scraper 211 is locked on the outer wall of the locking block 205. A slanted frame 206 is fixedly installed on the side of the push plate 204 away from the locking block 205. A slide column 207 is slidably arranged inside the slanted frame 206. A connecting plate 208 is fixedly installed at the end of the slide column 207. A sleeve block 209 is fixedly installed on the outer wall of the connecting plate 208. A limiting rod 210 is sleeved inside the sleeve block 209.
[0042] The outer wall of the scraper 211 has a slot and is adapted to engage with the outer wall of the locking block 205. The outer wall of the locking block 205 is set at an angle. Under the locking constraint of the locking block 205 and the scraper 211, the scraper 211 and the blade holder 104 can be quickly installed.
[0043] One end of the spring 203 is fixedly installed on the side of the upright block 201 near the locking block 205, and the other end of the spring 203 away from the upright block 201 is fixedly installed on the side of the push plate 204 away from the locking block 205. Under the elastic action of the spring 203, the locking block 205 that is not squeezed can be reset and pushed.
[0044] Among them, the inclined frame 206 is set at an angle, and there are two inclined frames 206, which are symmetrically distributed around the center line of the top surface of the tool holder 104. Under the restriction of the two inclined frames 206, the two locking blocks 205 can be pushed in opposite directions in conjunction with the sliding column 207.
[0045] When cleaning residual asphalt adhering to the outer wall of the mixer, select a suitable scraper 211 according to the shape of the device, and press its bottom against the inclined surface of the locking block 205. The locking block 205 is compressed, which drives the slide rod 202 to slide inside the vertical block 201 through the push plate 204, and compresses the spring 203 sleeved on the outer wall of the slide rod 202. When the locking block 205 is aligned with the slot opened on the side wall of the scraper 211, the locking block 205 is no longer compressed. Under the elastic action of the spring 203, it can push the push plate 204 and the locking block 205, so that the locking block 205 presses against the scraper 211. The scraper 211 can be quickly installed by snapping it in place. When replacing the scraper 211, press the sleeve block 209. The sleeve block 209 drives the connecting plate 208 and the sliding column 207 to move downward. Since the inclined frame 206 is set at an angle, under its restriction, the sliding column 207 slides and squeezes the inside of the inclined frame 206. Under its restriction, the two inclined frames 206 drive the two push plates 204 and the locking block 205 to move in opposite directions, so that the locking block 205 is no longer snapped into the outer wall of the scraper 211, and the scraper 211 can be quickly disassembled. This structure can quickly replace the scraper 211 and adapt it to the needs.
[0046] Example 3
[0047] Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below:
[0048] The protective unit 300 includes a first magnetic ring 301 fixedly installed on the outer wall of the wooden handle 100, a protective sleeve 302 provided above the first magnetic ring 301, a second magnetic ring 303 fixedly installed on the inner wall of the protective sleeve 302, and a third magnetic ring 304 provided on the inner side of the protective sleeve 302.
[0049] The inner wall of the second magnetic ring 303 is slidably disposed with the outer wall of the wooden handle 100. The second magnetic ring 303 is magnetically attracted to the first magnetic ring 301 and the third magnetic ring 304. Under their restriction, the protective sleeve 302 can be restricted to the outside of the wooden handle 100.
[0050] When using the cleaning equipment to clean asphalt, the protective sleeve 302 slides, and the second magnetic ring 303 fixedly installed on its inner wall slides on the outer wall of the wooden handle 100. Under the magnetic attraction between the second magnetic ring 303 and the first magnetic ring 301, the protective sleeve 302 can be restricted, and the cleaning work can be carried out. After use, in order to avoid the operator being burned by the residual heat of the scraper 211, the protective sleeve 302 is pulled away from the first magnetic ring 301 under its restriction. Under the magnetic attraction between the second magnetic ring 303 and the third magnetic ring 304, the scraper 211 can be covered by the protective sleeve 302 to avoid burns.
[0051] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
[0052] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.
[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
