Description

Technical Field

[0001] The present invention relates to the technical field of ore conveying machinery, and more specifically, to a conveying device for mine construction. Background Art

[0002] A mine mainly includes one or more mining workshops and some auxiliary workshops. Most mines also include a beneficiation plant. Mining refers to the exploitation of valuable natural mineral resources by manual or mechanical means. According to the different burial depths of the ore deposits and the requirements of technical and economic rationality, mining is divided into two methods: open-pit mining and underground mining. Open-pit mining is used for parts close to the surface and shallowly buried, and underground mining is used for deep parts. In the mining process, conveying equipment is required to transport the ore materials and transport the mined ore materials to the designated location.

[0003] Since the dust from the falling slag of the mine conveyor will accumulate on the crawler during operation, and the dust will be raised as the crawler runs, causing the surrounding working environment to be full of dust. The prior art installs multiple sets of sprinkler heads on the conveyor frame to reduce the dust generated during the operation of the machine through the atomization effect of the sprinkler heads. Although spraying water mist to reduce the dust on the stone can ensure a better dust removal effect, the stone powder after dust reduction will adhere to the transmission belt. Long-term use will cause the transportation negative pressure of the transmission belt to increase, affecting the transportation capacity of the conveying device. For this reason, we propose a conveying device for mine construction. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the driving plate and the movable plates on both sides are driven to move downward by the electric cylinder. At this time, the circular plates of the telescopic plate 1 and the telescopic plate 2 rotate counterclockwise with the circular plate as the axis. When the circular plates rotate counterclockwise, the protrusions 1 and the protrusions 2 are driven to rotate synchronously. At this time, a pressing roller is fixedly connected between the limit shafts 2 to tension the transmission belt. At the same time, the scraping roller fixed between the limit shafts 1 is against the lower end surface of the transmission belt.

Then, through the operation of the transmission belt, the cleaning rollers 1 and 2 and the upper surface of the transmission belt are cleaned of stone powder.

[0017] 3. In the present invention, when the insertion rod moves downward, the driving plate gives a downward force to the compression spring, causing the annular plate to rotate, thereby driving the telescopic rod to move in the sliding hole. When the telescopic rod moves to the initial section, the distance between the telescopic rods on both sides is the shortest. When the telescopic rod moves to the terminal section, the distance between the telescopic rods on both sides is the farthest. Therefore, when the telescopic rod moves, the rotating rod 1 and the rotating rod 2 in the telescopic rod are driven to move synchronously.

The blocking portion is attached to the upper surface of the transmission belt to further block the stone. In this way, the transported stone is blocked to ensure that it moves in the middle of the transmission belt, thereby reducing the possibility of the stone getting stuck in the gap.

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Embodiment 1 further describes a conveying device for mine construction proposed by the present invention, including a conveying frame 100, a conveying space 101 is formed in the conveying frame 100, the front and rear ends of the conveying frame 100 are rotatably connected with pulleys 102, a transmission belt 103 is set between the pulleys 102 on both sides, and the conveying frame 100 is fixedly connected with fixed plates 104 on both sides, and water distribution pipes 105 are respectively installed in the fixed plates 104 on both sides, and the water distribution pipes 105 are connected to the external water outlet pipes, and multiple groups of water inlet pipes 108 are arranged between the water distribution pipes 105 on both sides, and the multiple groups of water inlet pipes 108 are equidistantly arranged on the water distribution pipes 105, and the multiple groups of water inlet pipes 108 are correspondingly penetrated through openings 107 arranged in the conveying space 101, and three groups of sprinkler heads 110 are equidistantly installed at the bottom of the water inlet pipes 108. Three groups of spray heads 110 are correspondingly arranged just above the transmission belt 103. A feed bin 109 is installed on one side of the upper end surface of the conveyor frame 100. The outlet of the feed bin 109 corresponds to the position of the transmission belt 103, including a stone baffle 106 fixedly connected to the upper end surface of the conveyor frame 100. Openings 107 are provided on both sides of the stone baffle 106. A cleaning mechanism 200 is arranged in the conveyor frame 100. The cleaning mechanism 200 includes an auxiliary component 400 arranged in the conveyor frame 100. A driving member 201 is arranged on the upper end surface of the stone baffle 106. A linkage member 202 cooperating with the driving member 201 is arranged in the conveyor frame 100. A cleaning member 203 is arranged in the linkage member 202. The driving member 201 cooperates with the linkage member 202 so that the cleaning member 203 cleans the transmission belt 103. During the operation of the mine conveyor, dust from falling slag and rocks will accumulate on the crawler belt, and as the crawler belt runs, the dust will be raised, causing the surrounding working environment to be filled with dust. In the present invention, water distribution pipes 105 are fixedly installed on both sides of the conveyor frame 100, and multiple groups of water inlet pipes 108 are equidistantly arranged on the water distribution pipes 105. Figures 1 to 4 It can be seen that the water inlet pipe 108 is in an inverted concave shape, and three groups of spray heads 110 are arranged inside it. The dust generated when the machine is running is reduced by the atomization effect of the spray heads 110. Although the stone is reduced by spraying water mist, a better dust removal effect can be guaranteed, but the stone powder after dust reduction will adhere to the transmission belt 103. Long-term use will cause the transportation negative pressure of the transmission belt 103 to increase, affecting the transportation capacity of the conveying device. Therefore, this device further refines the existing technology; A cleaning mechanism 200 is provided in the conveyor frame 100, and the cleaning mechanism 200 cooperates with the driving member 201 and the linkage member 202 so that the cleaning member 203 cleans the transmission belt 103, and the cleaning mechanism 200 has three functions: first, cleaning the upper end surface of the transmission belt 103; second, driving the cleaning member 203 to scrape the stone powder on the lower end surface of the transmission belt 103 through the linkage member 202; and third, while the linkage member 202 is in operation, the transmission belt 103 is tensioned to ensure the normal transportation of the transmission belt 103 and the effective scraping of the stone powder; The self-cleaning mechanism 300 is also included in the cleaning mechanism 200. The self-cleaning mechanism 300 includes a rotating member 301 arranged in the auxiliary member 401. The driving member 201 is provided with a resisting member 302 that cooperates with the rotating member 301. The resisting member 302 is provided with a deflecting member 303. The rotating member 301 and the resisting member 302 cooperate to control the deflecting member 303. The device further refines the structure of the cleaning mechanism 200. Figures 6 to 11 It can be seen that when the driving member 201 is in operation, the cooperation of the positioning block 302i and the arc groove 302b causes the rotating member 301 to operate, and the rotating member 301 and the abutting member 302 cooperate to control the offset member 303, so that the scraper plate 1 303n and the scraper plate 2 303o in the offset member 303 scrape the powder on the outer surface of the cleaning roller 1 303c and the cleaning roller 2 303d; The auxiliary component 400 includes an auxiliary part 401 arranged in the conveying space 101, and a blocking part 402 is integrally formed in the auxiliary part 401. The auxiliary part 401 and the blocking part 402 cooperate to block the conveyed ore. Since the stone is prone to shaking during transportation, causing the stone to slip, or it may slip into the gap of the transmission belt 103 during use and get stuck there. Therefore, the present device further refines the existing technology, and is internally provided with an auxiliary part 401 and a blocking part 402 to block the transported stone and ensure that it moves in the middle of the transmission belt 103, thereby reducing the possibility of the stone getting stuck in the gap.

[0025] Working principle: When in use, pour the stone from the feed bin 109, then the stone slides to the transmission belt 103, the conveying motor drives the pulley 102 to rotate, so that the transmission belt 103 transports the stone, and by opening the valve of the external water outlet pipe, high-pressure water is transmitted from the water inlet pipe 108 to the spray head 110, and the spray head 110 atomizes the water, thus reducing the dust generated by the conveying machinery during transportation. After use, the stone powder after dust reduction will adhere to the transmission belt 103, and the cleaning part 203 is used to clean the stone by cooperating with the driving part 201 and the linkage part 202. The transmission belt 103 is cleaned, and its cleaning mechanism 200 has three functions. The first is to clean the stone powder adhered to the upper end surface of the transmission belt 103. The second is to drive the cleaning member 203 to scrape the stone powder on the lower end surface of the transmission belt 103 through the linkage member 202. The third linkage member 202 is tightened while operating to ensure the normal transportation of the transmission belt 103 and the effective scraping of the stone powder. In this way, the device cleans the transmission belt 103 from three directions at the same time, thereby reducing the adhesion of stone powder as much as possible. When the driving member 201 is operating, the cooperation between the positioning block 302i and the arc groove 302b enables the rotating member 301 to operate, and the rotating member 301 and the resistance member 302 cooperate to control the offset member 303, so that the scraper plate 1 303n and the scraper plate 2 303o in the offset member 303 scrape the powder on the outer surface of the cleaning roller 1 303c and the cleaning roller 2 303d, further ensuring the use effect of the device.

[0026] Embodiment 2 adds the following technical features on the basis of embodiment 1: the driving member 201 includes an electric cylinder 201a fixedly mounted on the upper end surface of the stone baffle 106, the output end of the electric cylinder 201a passes through one end of the stone baffle 106 and is fixedly connected to a driving plate 201b, the driving plate 201b correspondingly passes through the openings 107 on both sides, and the driving plate 201b extends downward on both sides to form a movable plate 201c, the linkage member 202 includes a telescopic plate 1 202a and a telescopic plate 2 202b rotatably connected to the movable plates 201c on both sides, and the corresponding positions on the conveying racks 100 on both sides are rotatably connected to circular plates 202c respectively, the protruding ends of the telescopic plate 1 202a and the telescopic plate 2 202b are correspondingly fixedly connected to the circular plate 202c, and the circular plates 202c on both sides are respectively integrally formed with a protrusion 1 202d and a protrusion 2 202e, and the protrusion 1 202d and the protrusion 2 202e are symmetrical along the axis of the circular plate 202c; Depend on Figures 4 to 7It can be seen that the stone baffle 106 is fixedly connected to the electric cylinder 201a, and the electric cylinder 201a serves as the output source when the cleaning mechanism 200 moves. The output end of the electric cylinder 201a is fixedly connected to the driving plate 201b, and the driving plate 201b and the movable plates 201c on both sides form an inverted concave structure. When the electric cylinder 201a works, the driving plate 201b and the movable plates 201c on both sides move synchronously, and the two sides of the movable plate 201c are respectively rotatably connected with the telescopic plate 1 202a and the telescopic plate 202b, and the protruding ends of the telescopic plate 1 202a and the telescopic plate 202b are correspondingly fixedly connected to the circular plate 202c. It can be obtained that when the movable plate 201c moves downward, the circular plate 202c of the telescopic plate 1 202a and the telescopic plate 202b is driven to rotate with the circular plate 202c as the axis. The cleaning member 203 includes an arc hole 1 203a and an arc hole 203b arranged on both sides of the conveyor frame 100, and a limit axis 1 203c and a limit axis 203d are arranged on the protruding portion 1 202d and the protruding portion 202e on both sides relative to the positions of the arc hole 1 203a and the arc hole 203b. The limit axis 1 203c and the limit axis 2 203d are correspondingly slidably connected in the arc hole 1 203a and the arc hole 2 203b, and a scraping roller 203e is fixedly connected between the limit axis 1 203c on both sides, and a scraping strip portion 203f is integrally formed on the scraping roller 203e, and the scraping strip portion 203f is inwardly recessed to form a scraping groove 203g, and a pressing roller 203h is installed between the limit axis 2 203d on both sides, and the pressing roller 203h is arranged on the inner side of the transmission belt 103, and the scraping roller 203e is arranged on the lower end surface of the transmission belt 103; In order to ensure the cleaning effect of the transmission belt 103, the present invention symmetrically provides an arc hole 1 203a and an arc hole 203b on both sides of the conveyor frame 100. When the protrusion 1 202d and the protrusion 202e on the circular plate 202c rotate, the limit shaft 1 203c and the limit shaft 2 203d are correspondingly slidably connected in the arc hole 1 203a and the arc hole 2 203b. Figures 4 to 7 It can be seen that when the movable plate 201c moves downward, its circular plate 202c moves counterclockwise, and when the movable plate 201c moves upward, its circular plate 202c moves clockwise, and the angle of its movement is the arc length of the arc hole 1 203a and the arc hole 2 203b; Therefore, the device is provided with a scraper roller 203e fixed between the limiting shaft 1 203c, and the scraper strip on the scraper roller 203e contacts the lower end surface of the conveyor belt, thereby scraping off the stone powder on the transmission belt 103. Meanwhile, a pressing roller 203h is fixedly connected between the limiting shaft 203d, so that the transmission belt 103 is tensioned, and the scraper roller 203e is guaranteed to completely scrape off the stone powder on the surface of the transmission belt 103 as much as possible. The present invention further defines the pressing roller 203h and the scraper roller 203e, and the pressing roller 203h is larger in diameter than the scraper roller 203e, so that the pressing roller 203h is guaranteed to contact the transmission belt 103 before the scraper roller 203e contacts the transmission belt 103, thereby ensuring the tension of the transmission belt 103. Working principle: It can be seen from Example 1 that when the transmission belt 103 needs to be cleaned, the electric cylinder 201a drives the driving plate 201b and the movable plates 201c on both sides to move downward. At this time, the circular plates 202c of the telescopic plates 1 202a and 202b rotate counterclockwise with the circular plate 202c as the axis. When the circular plate 202c rotates counterclockwise, it drives the protrusions 1 202d and the protrusions 2 202e to rotate synchronously. At this time, a pressing roller 203h is fixedly connected between the limit shafts 203d to tension the transmission belt 103. At the same time, the scraping roller 203e fixed between the limit shafts 1 203c is against the lower end surface of the transmission belt 103. In this way, during transmission and transportation, the tensioning force of the pressing roller 203h enables the scraping roller 203e to effectively scrape off the stone powder on the transmission belt 103.
