Description
Technical Field
[0001] This utility model relates to the field of dust suppression technology in working faces, specifically a dust source tracking spray device for fully mechanized mining faces. Background Technology
[0002] The coal mining face refers to the primary production site of coal. It is characterized by a small working space, numerous mechanical equipment, poor visibility, and high temperature. Safety accidents occur frequently in the face, which seriously affects the safety management of the entire coal mine. It is a key area in the safety management of coal mines.
[0003] Existing coal mining faces are prone to generating dust and other gases during operation, which affects the working environment. When dust is generated, water spraying is often used to suppress it. However, the single spraying location can lead to poor dust suppression effect. Moreover, due to different mining environments, a lot of dust can adhere to the foundation of the working face, affecting the work of personnel. Therefore, it is necessary to improve the dust suppression method of the working face. Utility Model Content
[0004] The purpose of this invention is to provide a dust source tracking spray device for fully mechanized mining faces to solve the problems mentioned in the background art.

[0013] The drain pipe is equipped with an atomizing nozzle.
[0014] Preferably, the driving mechanism three is installed with a support, and the top end surface of the support is installed on the bottom end surface of the base.
[0015] Preferably, the air pump is provided with the discharge pipe one and the discharge pipe two respectively, and the one end of the discharge pipe two away from the air pump is embedded and fixed in the bag-type dust collector. When the air pump is started, the air pump can extract and discharge the gas in the bag-type dust collector through the discharge pipe two, and the extracted gas can be discharged through the discharge pipe one.
[0016] Preferably, the one end of the extraction pipe away from the bag-type dust collector penetrates through the base and is embedded and fixed in the gas collecting cover, and the extraction pipe is in gas communication with the bag-type dust collector. When the gas in the bag-type dust collector is extracted, the bag-type dust collector can intake the gas through the extraction pipe.
[0017] Preferably, the top end surface of the water storage tank is embedded and fixed with the water inlet pipe, and the water inlet pipe is in liquid communication with the water storage tank. The water for dust suppression can be injected into the water storage tank through the water inlet pipe for storage.
[0018] Preferably, the left end surface of the fixing frame is welded with the guide frame one, and the guide frame one is slidingly sleeved in the frame one. The left end surface of the fixing frame can be installed and limited by the guide frame one slidingly sleeved in the frame one.
[0019] Preferably, the right end surface of the fixing frame is welded with the guide frame two, and the guide frame two is installed on the lead screw through threads. The right end surface of the fixing frame is installed by the guide frame two installed on the lead screw through threads.
[0020] Preferably, the water storage tank is installed with a water pump, the water pump is provided with an extension pipe, and the one end of the extension pipe away from the water pump is embedded and fixed in the drain pipe. The water in the water storage tank can be extracted and injected into the drain pipe through the extension pipe by the water pump provided with the extension pipe when the water pump is opened, and the extension pipe can be used in cooperation with the rotation and up-down movement of the drain pipe.
[0021] Compared with the prior art, the utility model has the beneficial effects as follows:
[0022] 1. This utility model, by setting up a baghouse dust collector, allows workers to drive the drive wheel to rotate when performing dust source tracking and spray dust suppression operations at the coal mining face. The rotation of the drive wheel, in turn, drives the driven wheel to rotate, and this chain reaction causes the mounting shaft and its tires to roll. The rolling of the tires causes the base to move until it reaches the location of the dust source. During the movement, the air pump draws in and discharges the gas inside the baghouse dust collector through the discharge pipe. At the same time, the extraction pipe maintains gas communication with the baghouse dust collector, ensuring that when the gas inside the baghouse dust collector is drawn in, it can smoothly enter through the extraction pipe for air intake. At this time, the gas collection hood and the air intake process work together to effectively capture and extract dust from the surface of the mining face, allowing the dusty gas to enter the baghouse dust collector and be filtered by the internal filter bags, thereby preventing dust accumulation and maintaining a good working environment at the working face.
[0023] 2. This utility model, by setting up a drainage pipe, enables dust suppression spraying operations at the coal mining face with dust source tracking. Workers first move the base to the location of the dust source. Then, they start the water pump, which draws water from the storage tank and injects it into the drainage pipe via a telescopic pipe. As the water passes through the drainage pipe, it is sprayed out by atomizing nozzles, forming an effective dust suppression barrier that covers the longwall mining face and effectively suppresses dust. During the spraying operation, to ensure the stability and flexibility of the drainage pipe, both ends of the fixed frame are limited and guided by guide frame one and frame two, respectively. At this time, workers can activate drive mechanism one to drive the lead screw to rotate. The rotation direction of the lead screw determines the up-and-down movement direction of the fixed frame, thereby adjusting the spraying height of the drainage pipe. Furthermore, while adjusting the spraying height, workers can also activate drive mechanism two to drive the drainage pipe to rotate. This operation allows for free adjustment of the spray angle, effectively avoiding the problem of poor dust suppression effect that may be caused by a single spray position. It ensures that the entire longwall mining face can be fully and evenly covered by spray, thereby significantly improving the dust suppression effect and optimizing the working environment.
