[0006] Two adjustable baffles are hingedly arranged between the two side baffles;

[0007] A first movable arm is provided between the connecting sleeve and the dust collecting hood; the implementation purpose of the first movable arm is to adjust the direction of the integrated hood part through the action of the movable arm, that is, the dust collecting hood is turned in the hinge direction through the action of the first movable arm;

[0008] The side baffle is provided with a movable arm assembly, and the piston part of the movable arm assembly is hinged with the regulating baffle.

[0009] The effect achieved in this way is to adjust the distance between the two adjustment baffles through the action of the boom group, that is, to adjust the opening of the air outlet accordingly.

[0010] That is to say, the device drives the first movable arm to flexibly adjust the direction of the opening of the dust collecting cover;

[0011] The opening and closing degree between the baffles is adjusted by the action of the movable arm group, that is, the opening degree of the air outlet is adjusted.

[0012] The beneficial effects of the utility model are: the utility model has a simple structure and a low cost, and the orientation adjustment and port opening adjustment of the dust collecting hood are achieved through a simple structure, and on this basis, it can be flexibly applied to various working conditions, and the implementation effect of dust collection or exhaust is better, and it has more market promotion value.

[0019] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model discloses a variable-angle dust hood, comprising a connecting sleeve 1, wherein the connecting sleeve 1 is in the form of a cylinder and is used to connect the end position of an exhaust device such as an air duct or an air cylinder;

[0021] The front part of the connecting sleeve 1 is hingedly provided with a dust collecting cover, and the dust collecting cover includes an assembly ring 2, and the front end surface of the assembly ring 2 is fixedly provided with two opposite side baffles 4;

[0022] Between the two side baffles 4, two-sided adjustment baffles 5 are hingedly arranged on the assembly ring;

[0023] A first movable arm 3 is provided between the connecting sleeve 1 and the dust collecting hood; the implementation purpose of the first movable arm 3 is to adjust the direction of the integrated hood part through the action of the movable arm, that is, the dust collecting hood is turned in the hinge direction through the action of the first movable arm 3;

[0024] The side baffle plate 4 is provided with a boom assembly 6 , and a piston portion of the boom assembly 6 is hinged to the regulating baffle plate 5 .

[0025] The effect achieved in this way is that the distance between the two adjustment baffles 5 is adjusted by the action of the movable arm group 6, that is, the opening of the air outlet is correspondingly adjusted.

[0026] When the device is in use, the opening of the dust collecting cover part is flexibly adjusted in direction by driving the first movable arm 3;

[0027] The opening and closing degree between the baffles 5 is adjusted by the action of the movable arm group 6, that is, the opening degree of the air outlet is adjusted.

[0028] Furthermore, the connection sleeve 1 and the assembly ring 2 are respectively provided with two ear plates, and the ear plates are arranged correspondingly;

[0029] The connecting sleeve 1 and the assembly ring 2 are hinged via ear plates.

[0030] The effect achieved in this way is that the connecting sleeve 1 and the dust collecting hood can achieve horizontal, vertical or oblique horizontal swing. The horizontal swing mentioned here refers to swinging in two relative directions such as left and right or up and down. Its specific assembly form, that is, the swinging direction can be flexibly adjusted according to the on-site working conditions.

[0031] Furthermore, the swing direction of the adjusting baffle 5 is perpendicular to the swing direction of the dust collecting hood.

[0032] Furthermore, the first movable arm 3 is arranged inside the connecting sleeve 1 and the dust collecting hood;

[0033] The boom assembly 6 comprises two booms, which are respectively arranged on the side baffles 4 and connected to an adjusting baffle 5 .

[0034] Preferably, the first boom 3 and the two booms of the boom assembly 6 are both in the form of cylinders.

[0035] When the utility model is used, a flexible sealing material such as a wind tube is sleeved on the gap between the connecting sleeve 1 and the dust collecting hood to form a sealing sleeve that does not affect the movement of the dust collecting hood;

[0036] By driving the first movable arm 3, the opening of the dust collecting cover part can be flexibly adjusted in direction;

[0037] The opening and closing degree between the baffles 5 is adjusted by the action of the movable arm group 6, that is, the opening degree of the air outlet is adjusted.
