[0023] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-3 In the first embodiment, a blasthole marking device includes:

[0025] The box body 10 has lifting holes 20 distributed along the box body 10 on one side wall;

[0026] Two gears 30 are rotatably disposed in the box body 10, and the two gears 30 are respectively located at two ends of the two lifting holes 20;

[0027] The belt teeth 40 are respectively sleeved on the two gears 30 at both ends and mesh with the gears 30;

[0028] A connecting plate 60, one end of which is fixedly connected to an inner wall of one side of the belt tooth 40, and the other end of which slides through the lifting hole 20;

[0029] A mounting plate 70, fixedly connected to an end of the connecting plate 60 extending outside the box body 10, and having a mounting hole 71;

[0030] The strip 50 has two ends respectively fixedly connected to the outer wall of the belt teeth 40, and the strip 50 is sleeved on the outer periphery of the belt teeth 40;

[0031] The strip 50 has a scale 51 , and one side wall of the box body 10 has two through holes 52 at positions corresponding to the strip 50 , and the strip 50 passes through the two through holes 52 .

[0032] This embodiment is implemented as follows:

[0033] Pass the nozzle through the mounting hole 71 and install it on the mounting plate 70;

[0034] When the present application is in use, when the connecting plate 60 is located at the lowest end of the lifting hole 20, the zero scale of the strip 50 is located at the position extending out of the box body 10 between the two through holes 52;

[0035] Then, according to the height of the blasthole, the strip 50 is pulled, and the strip 50 moves in the through hole 52, so that the strip 50 drives the belt teeth 40 to rotate, and the belt teeth 40 drives the gear 30 to rotate, so that the belt teeth 40 can drive the connecting plate 60 to move in the lifting hole 20, and the connecting plate 60 drives the mounting plate 70 to move, so that the nozzle on the mounting plate 70 can be moved to the position of the blasthole, and then the spraying of the nozzle is achieved by operating the sprayer. During the use of the present application, the box body is made of lightweight plastic material, which can effectively reduce the labor intensity of workers moving the box body 10.

[0036] The advantage of the present application over the prior art is that it can realize the marking of blastholes in a mine where the vehicle body is inconvenient to move.

[0037] See also Figure 1 , a pointer mark 80 is provided on the outer wall of the box body 10, and the pointer mark 80 is located between the two through holes 52;

[0038] The pointer mark 80 facilitates workers to observe the exact height of the nozzle on the mounting plate 70, thereby improving the positioning accuracy.

[0039] See also Figure 2 , 3 , the inner wall of the gear 30 has a cavity;

[0040] Providing a cavity inside the gear 30 is helpful to reduce the overall weight of the box body 10 .

[0041] The mounting plate 70 and the connecting plate 60 are both plastic plates;

[0042] Using plastic plates to make the mounting plate 70 and the connecting plate 60 can reduce weight and reduce the labor intensity of workers.

[0043] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
