Detailed Embodiment

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a conveyor belt dust suppressant spraying device includes a bracket assembly 1. The bracket assembly 1 includes an n-shaped bracket 102 and a connection base 104. There are multiple connection bases 104, and every two of the multiple connection bases 104 form a group. Moreover, multiple groups of connection bases 104 are respectively fixed on the outer sides of the two vertical parts and the horizontal part of the fixed seat 101;

[0031] The n-type bracket 102 is connected with a dust suppression component 2 through a connecting base 104. The n-type brackets 102 are distributed on the outer side and the top of the conveyor belt frame, and the dust suppression component 2 is used to spray dust suppressant above the conveyor belt;

[0032] The dust suppression component 2 includes a spraying unit and an adjusting unit. The adjusting unit is used to adjust the spraying angle of the spraying unit according to the distribution distance of the bracket components 1, so as to realize the all-round dust suppression of the conveyor belt in the area between two bracket components 1;

[0033] A locking component 3 is also arranged on the spraying unit, and the locking component 3 is used to fix the spraying angle of the spraying unit;

[0034] The spraying unit includes a transverse spray pipe 201, a linkage bevel gear 202, a connecting hose 205, a shunt pipe 206, a spray head 207 and a main water pipe 208;

[0035] The transverse spray pipe 201 and the vertical spray pipe 203 are respectively rotatably connected to a plurality of connecting bases 104, and the transverse spray pipe 201 is parallel to the transverse part of the fixed seat 101, and the vertical spray pipe 203 is flush with the vertical part of the fixed seat 101;

[0036] The connecting hoses 205 are respectively connected between the two ends of the transverse spray pipe 201 and the tops of the two vertical spray pipes 203. The shunt pipe 206 is fixed to the bottom end of one vertical spray pipe 203, and the spray heads 207 are fixed to one side of the transverse spray pipe 201 and the vertical spray pipe 203;

[0037] The plurality of shunt pipes 206 in the plurality of spraying units are connected and communicated with the main water pipe 208. The dust suppressant is transported to the inside of the vertical spray pipe 203 and the transverse spray pipe 201 through an external transfer pump, the main water pipe 208 and the shunt pipe 206 and is sprayed out through the spray heads 207, so as to realize the covering dust suppression of the two sides and the upper part of the conveyor belt by the dust suppressant;

[0038] The adjusting unit includes a linkage bevel gear 202 and a transmission bevel gear 204;

[0039] The linkage bevel gears 202 are symmetrically fixed to the outer sides of the two ends of the transverse spray pipe 201, and the two transmission bevel gears 204 are respectively fixed to the outer tops of the two vertical spray pipes 203, and the two transmission bevel gears 204 are respectively engaged with the two linkage bevel gears 202;

[0040] When one vertical spray pipe 203 rotates, the synchronous rotation of the transverse spray pipe 201 and the other vertical spray pipe 203 can be driven through the transmission of the linkage bevel gear 202 and the transmission bevel gear 204, so as to realize the rotation operation of the vertical spray pipes 203 synchronously towards the inside or synchronously towards the outside;

[0041] The locking component 3 includes a fixed circular block 301, an arc-shaped rail groove 302, and a locking bolt 303;

[0042] The fixed circular block 301 is fixed to the outside of a vertical spray pipe 203 and fits against the upper surface of a connection base 104. The arc-shaped rail groove 302 is opened at the top of the fixed circular block 301 and penetrates to the bottom of the fixed circular block 301. The locking bolt 303 penetrates through the arc-shaped rail groove 302 and is threadedly connected to the connection base 104. A threaded hole for tightening the stud of the locking bolt 303 is opened on the connection base 104;

[0043] Through the tight extrusion between the fixed circular block 301 and the connection base 104 by the locking bolt 303, the rotational locking of the vertical spray pipe 203 is realized.

[0044] In this embodiment, it should be supplemented and explained that multiple groups of the bracket components 1 are uniformly arranged along the long side direction of the conveyor belt;

[0045] After the bracket components 1 are installed, the orientation angle of the spray heads 207 can be adjusted according to the distance between two adjacent groups of bracket components 1. The operation steps are as follows:

[0046] First, loosen the locking bolt 303. At this time, the locking bolt 303 releases the extrusion of the fixed circular block 301, and then releases the rotational locking of the vertical spray pipe 203. At this time, the vertical spray pipe 203 can be rotated. This vertical spray pipe 203 drives a linkage bevel gear 202 to rotate through the drive bevel gear 204 at its top. This linkage bevel gear 202 drives the horizontal spray pipe 201 to rotate. The horizontal spray pipe 201 drives another vertical spray pipe 203 to rotate through the transmission of another linkage bevel gear 202 and another drive bevel gear 204. Then, the synchronous adjustment of the orientations of the spray heads 207 on the horizontal spray pipe 201 and the two vertical spray pipes 203 is realized, so that the multiple spray heads 207 rotate inwards or outwards synchronously. In this way, the contraction angle of the trajectories of the dust suppressant sprayed by the multiple spray heads 207 can be changed (it should be noted that the trajectories of the dust suppressant sprayed by the three groups of spray heads 207 on the horizontal spray pipe 201 and the two vertical spray pipes 203 are in a trapezoidal state, so as to realize the dust wrapping above the conveyor belt and promote the dust to fall back onto the conveyor belt);

[0047] When the contraction opening of the dust suppressant trajectory (i.e., the position at the end far from the spray head 207) is located in the middle of the three groups of spray heads 207 in the next group of dust suppression components 2 or exceeds the position of the three groups of spray heads 207, the rotation of the vertical spray pipe 203 can be stopped. In this way, the dust suppression coverage areas between two adjacent groups of dust suppression components 2 overlap, and then the all-round dust suppression effect is ensured. Finally, tighten the locking bolt 303.

[0048] Please refer specifically to Figures 1 to 3, the bracket assembly 1 further includes a fixed seat 101 and fastening nuts 103;

[0049] The fixed seat 101 is welded and fixed to the outside of the conveyor belt frame. A vertical portion of the n-shaped bracket 102 penetrates through the upper and lower ends of the fixed seat 101. The fastening nuts 103 are symmetrically distributed at the upper and lower ends of the fixed seat 101 and are threadedly connected to the n-shaped bracket 102 to realize the relative fixation of the n-shaped bracket 102 and the fixed seat 101;

[0050] The fixed round block 301 and the shunt pipe 206 are connected to the same vertical spray pipe 203, and the vertical portion of the n-shaped bracket 102 in contact with the n-shaped bracket 102 is on the same side as this vertical spray pipe 203.

[0051] In this embodiment, it should be supplemented that: an external thread is formed at the position where the vertical portion of the n-shaped bracket 102 contacts the fixed seat 101, and the height of the other vertical portion of the n-shaped bracket 102 is lower than the height of this vertical portion. By the fitting of the two fastening nuts 103 with the upper and lower ends of the fixed seat 101, the height and rotational fixation of the n-shaped bracket 102 can be realized;

[0052] When it is necessary to replace the faulty spray head 207, the fastening nut 103 can be loosened, so that the n-shaped bracket 102 can be rotated or disassembled, and then all the spray heads 207 can be moved away from the conveyor belt, so as to facilitate the replacement operation of the spray head 207. After the replacement is completed, it can be reset. Compared with the traditional fixed gantry structure, its maintenance efficiency is faster and the operation is easier.

[0053] The above-mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
