[0027] See also Figure 1 - Figure 5 , Figure 1The present invention is a schematic diagram of a slag blocking device in an embodiment of the present invention. The slag blocking device includes a fixed shell 100 and a movable shell 200. Both the fixed shell 100 and the movable shell 200 are arc-shaped structures. An arc-shaped slide groove 110 is provided on one end side of the fixed shell 100. One end side of the movable shell 200 extends into the notch of the arc-shaped slide groove 110 and is slidably connected to the arc-shaped slide groove 110. The movable shell 200 can slide along the path of the arc-shaped slide groove 110 to the other end side of the movable shell 200 and close with the fixed shell 100 to form a circle.

[0028] In this embodiment, the fixed housing 100 is mounted on the road coring machine bracket 700 (see attached Figure 1 The middle bracket 700 (not described in detail below) is provided with one side of the drill bit (the drill bit is an existing structure, not shown in the figure), and the fixed shell 100 is made coaxial with the drill bit of the road coring machine. Before starting the drill bit, the movable shell 200 is pulled first, and the movable shell 200 slides in the arc-shaped slide groove 110 of the fixed shell 100, so that the side of the movable shell 200 located outside the arc-shaped slide groove 110 moves to contact with one side of the fixed shell 100, thereby forming a complete circle, and then wrapping the drill bit of the road coring machine. At this time, the drill bit of the road coring machine is started and the operation is started. The device surrounds the working end of the drill bit by cooperating with the fixed shell 100 and the movable shell 200 to form a circular ring, which better blocks the splashing of mud and gravel and ensures the operation effect.

[0029] In one embodiment, see Figure 1 - Figure 2 , both sides of the fixed housing 100 are fixedly connected with mounting plates 120, and the mounting plates 120 are provided with fastening screws 121;

[0030] In this embodiment, the fixed housing 100 is connected to the bracket 700 via the mounting plate 120 , and then the fixed housing 100 is fixed to the bracket 700 via the fastening screws 121 .

[0031] In one embodiment, see Figure 3 - Figure 5 One side of the arc-shaped slide groove 110 is closed, and two fixing rods 111 are fixedly connected to the inner wall of the closed side of the arc-shaped slide groove 110. One end of the fixing rod 111 extends to the notch of the arc-shaped slide groove 110. A circular slide groove 210 is provided on one side of the movable housing 200 located in the arc-shaped slide groove 110. The bottom of the circular slide groove 210 extends to the side of the movable housing 200 located outside the fixed housing 100, and the circular slide groove 210 is adapted to the fixing rod 111;

[0032] In this embodiment, the movable housing 200 slides outside the fixing rod 111 through the circular sliding groove 210, thereby improving the stability of the movable housing 200 when sliding.

[0033] In one embodiment, see Figure 3 - Figure 5 The bottom of the arc-shaped slide groove 110 is open, and a connecting block 220 is slidably connected to the bottom of the arc-shaped slide groove 110. The connecting block 220 is fixedly connected to one side of the bottom of the moving housing 200. One end of the connecting block 220 extends toward the center of the fixed housing 100. A scraper strip 230 is slidably connected to the inner side wall of the fixed housing 100. The bottom end of the scraper strip 230 is fixedly connected to one side of the top of the connecting block 220.

[0034] In this embodiment, when the movable housing 200 moves, the scraper bar 230 can be driven to move together through the connecting block 220 . When the scraper bar 230 moves, it can scrape the inner wall of the fixed housing 100 .

[0035] In one embodiment, see Figure 1 - Figure 5 A fixed ring brush 300 is provided on the inner side of the top of the fixed housing 100, and a dynamic ring brush 400 is provided below the fixed ring brush 300. The dynamic ring brush 400 is slidably connected to the inner side wall of the top of the fixed housing 100. The dynamic ring brush 400 is semicircular and fixedly connected to a side close to the dynamic housing 200. The dynamic ring brush 400 can move together with the dynamic housing 200.

[0036] In this embodiment, the dynamic ring brush 400 moves with the movement of the dynamic housing 200. When the dynamic housing 200 and the fixed housing 100 form a complete circle, the fixed ring brush 300 and the dynamic ring brush 400 also form a complete circle to ensure that the bristles cover the outside of the drill bit of the road coring machine more evenly.

[0037] Furthermore, the bristles can not only brush the outside of the drill bit, but also ensure that when the fixed housing 100 and the movable housing 200 face drill bits of different sizes, no gap will be left between the drill bits.

[0038] In one embodiment, see Figure 1 - Figure 3 , a paddle 500 is provided on the top of one side of the movable housing 200 located outside the fixed housing 100, and a magnetic strip 600 is provided on the end sides of the fixed housing 100 and the movable housing 200 that are adapted to each other;

[0039] In this embodiment, the paddle 500 can be used to drive the movable housing 200 to slide in the arc-shaped slide groove 110 of the fixed housing 100, so that the two magnetic strips 600 are in contact with each other, which can limit the separation of the movable housing 200 and the fixed housing 100 to a certain extent, further improving the stability of the device during operation.

[0040] In one embodiment, see Figure 4 , the bottoms of the fixed housing 100 and the movable housing 200 are flush, and neither of them exceeds the bottom of the bracket 700;

[0041] In this embodiment, a certain gap is left between the bottom of the fixed housing 100 and the movable housing 200 and the ground to ensure that the mud can be discharged;

[0042] Furthermore, the arc length of the movable housing 200 is greater than the arc length of the fixed housing 100 . After the movable housing 200 slides to contact one side of the fixed housing 100 , a portion of the other side of the movable housing 200 remains inside the fixed housing 100 .

[0043] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the present invention is described in detail: the fixed shell 100 is installed on the side of the drill bit of the road coring machine bracket 700, and the fixed shell 100 is made coaxial with the drill bit of the road coring machine. Before starting the drill bit, the movable shell 200 is pulled by the paddle 500, and the movable shell 200 slides in the arc-shaped slide groove 110 of the fixed shell 100, so that the side of the movable shell 200 located outside the arc-shaped slide groove 110 moves to contact with one side of the fixed shell 100, thereby forming a complete circle, and then the drill bit of the road coring machine is wrapped, and the magnetic strips 600 on the ends of the fixed shell 100 and the movable shell 200 are attracted to each other, so as to limit the separation of the two shells. Then, the drill bit of the road coring machine is started and the operation is started. The present device cooperates with the fixed shell 100 and the movable shell 200 to form a circular ring to surround the working end of the drill bit, thereby better blocking the splash of mud and gravel and ensuring the operation effect.
