DETAILED DESCRIPTION
[0021] The utility model will be further described below in combination with the drawings and embodiments.
[0022] First embodiment
[0023] Please refer to Figure 1 , Figure 2 , Figure 3 Among them, Figure 1 A schematic diagram of the structure of the first embodiment of the dovetail slotted sweeper blade provided by this utility model; Figure 2 for Figure 1 A side view of the blade body shown; Figure 3 for Figure 1 The image shows a three-dimensional view of the blade body. The dovetail-groove type sweeper blade includes: blade body 1;
[0024] The blade body 1 has positioning grooves 2 on both sides, and the top of the positioning grooves 2 has an angled dovetail structure. The blade body 1 has an internal steel core 3.
[0025] The bevel angle of the positioning groove 2 is 5-80°, the arc segment of the positioning groove 2 is 3-30mm, the center distance between the two positioning grooves 2 is 300-3000mm, the bottom width of the blade body 1 is 20-120mm, and the steel core thickness is 5-30mm.
[0026] The outer contour of the blade body 1 is arc-shaped and its surface is smooth.
[0027] The working principle of the dovetail groove type sweeper blade provided by this utility model is as follows:
[0028] After the blade body 1 is installed through the positioning groove 2, the top of the blade body 1 contacts the surface of the belt. As the belt moves, the blade body 1 scrapes off the water-containing material on the belt. The outer contour of the blade body 1 adopts an arc design, and the swept material slides off with the blade body 1.
[0029] Compared with related technologies, the dovetail slot type sweeper blade provided by this utility model has the following beneficial effects:
[0030] After the blade body 1 is installed through the positioning groove 2, the positioning groove 2 has a dovetail structure with an angled top, which makes installation convenient and not easy to loosen. The top of the blade body 1 contacts the surface of the belt. As the belt moves, the blade body 1 scrapes off the water-containing material on the belt. The outer contour of the blade body 1 adopts an arc design and the surface is smooth. The swept material slides off with the blade body 1 and is not easy to accumulate.
[0031] Second Embodiment
[0032] Please refer to the following: Figures 4-5 Based on the dovetail slot type sweeper blade provided in the first embodiment of this application, the second embodiment of this application proposes another dovetail slot type sweeper blade. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0033] Specifically, the dovetail slot type sweeper blade provided in the second embodiment of this application differs in that the blade body 1 includes a connecting part 1a and a contact part 1b, which are detachably connected by an installation component 4. A first groove 5 is provided on the connecting part 1a, and a second groove 6 is provided on the contact part 1b. A sliding block 7 is slidably connected inside the first groove 5. A tension spring 8 is provided between the bottom of the sliding block 7 and the second groove 6. A connecting ring 9 is provided on the top of the sliding block 7. A pressure sensor 10 is installed inside the second groove 6, and a buckle 11 is installed inside the second groove 6.
[0034] The depth of the second groove 6 can be selected according to actual needs, so that the wear level of the contact part 1b can be set according to actual needs and it needs to be replaced.
[0035] The pressure sensor 10 is electrically connected to an external alarm device. When the pressure sensor 10 senses pressure, it can trigger an alarm through the alarm device.
[0036] The connecting ring 9 is engaged inside the buckle 11, and the tension spring 8 is in a stretched state.
[0037] The bottom of the sliding block 7 is provided with a protective pad 12, which can be made of rubber, to protect the pressure sensor 10 when the sliding block 7 is pressed down.
[0038] The mounting assembly 4 includes a fixing block 41, on which two positioning bolts 42 are mounted, and screw holes 13 are provided on both the connecting part 1a and the contact part 1b.
[0039] The contact part 1b and the connecting part 1a are fixed by the threaded connection between the positioning bolt 42 and the screw hole 13.
[0040] Preferably, a positioning pin and a positioning groove can also be provided between the contact part 1b and the connecting part 1a, so that the connection is more stable by inserting the positioning pin and the positioning groove.
[0041] Compared with related technologies, the dovetail slot type sweeper blade provided by this utility model has the following beneficial effects:
[0042] The detachable connection between the contact part 1b and the connecting part 1a allows the contact part 1b to be disassembled via the mounting component 4 when it becomes severely worn during operation. This allows for individual replacement of the contact part 1b without the need for overall replacement, reducing operating costs. Furthermore, when the contact part 1b wears down to the second groove 6, the clip 11 will disengage and fall off, causing the tension spring 8 to rebound and the sliding block 7 to move downwards and press against the pressure sensor 10. The pressure sensor 10 then triggers an alarm via an external device, reminding the operator to replace it, thus serving an alarm function.
[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
