Description

Technical Field

[0001] The utility model relates to the technical field of tunnel boring machines, in particular to an auxiliary dust reduction device which is convenient for cleaning a filter screen. Background Art

[0002] A roadheader is a machine used to dig tunnels on a flat surface. There are many types of roadheaders: according to the working object, they are divided into ordinary machines and tunnel boring machines; according to the working method, they are divided into open roadheaders and shield roadheaders. They are mainly composed of a traveling mechanism, a working mechanism, a loading mechanism, and a transfer mechanism. As the traveling mechanism moves forward, the cutting head in the working mechanism continuously breaks up the rock and transports the broken rock away.

[0003] And in the application document with publication number CN216922199U, an auxiliary dust reduction device for a tunnel boring machine is mentioned. The dust reduction device starts an auxiliary fan to allow air to pass through a first barrier layer to block part of the dust carried, and then the air falls down to the surface of the second barrier layer through water mist attached to the dust surface, making it easier for operators to manipulate the components in the device to reduce dust. This can prevent the tunnel boring machine from getting wet during a long period of dust reduction, and reduce the impact of direct on-site spraying of water mist on the normal use of the tunnel boring machine. However, there are still certain defects that need to be optimized. The specific defects are as follows: the position of the auxiliary fan of the existing auxiliary dust reduction device is fixed, the dust coverage area that can be inhaled is small, and the dust reduction effect is poor. At the same time, the existing dust reduction device is not convenient to clean when the barrier layer is saturated during use, which affects the dust reduction efficiency.

[0004] Therefore, it is particularly important to design an auxiliary dust reduction device that is easy to clean the filter to change the above technical defects and improve overall practicality. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. In the utility model, an auxiliary dust reduction device is provided for facilitating the cleaning of the filter screen. The structure of the first electric telescopic rod, the filter plate, the connecting rod and the spherical hammer is utilized. When the filter plate is saturated, the first electric telescopic rod is started so that the pressure pad squeezes the connecting rod until the compression spring is contracted. Then the first electric telescopic rod is withdrawn so that the connecting rod drives the spherical hammer to perform a pendulum motion and hit the filter plate. At this time, the saturated dust on the filter plate falls off through the impact and falls into the collection box. This solves the problem that the existing dust reduction device is inconvenient to clean when the barrier layer is saturated during use, which affects the dust reduction efficiency.

[0016] 2. In the utility model, an auxiliary dust reduction device is set up to facilitate cleaning of the filter. The structure of the second electric telescopic rod, the suction cup, the spray device and the filter is utilized. By turning on the air inlet fan, the second electric telescopic rod is started to drive the suction cup to move up and down to cover a larger area. At this time, the dust is sucked into the interior of the suction cup, and then water is injected into the interior of the spray device through the water inlet box. At this time, the water mist impacts the filter, and then is filtered through the filter and discharged through the water outlet, thereby solving the problem that the auxiliary fan of the existing auxiliary dust reduction device is fixed in position, the dust that can be sucked in covers a small area, and the dust reduction effect is poor.
