DETAILED DESCRIPTION

[0023] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0024] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 6 As shown, a transmission belt for mining production provided by an embodiment of the utility model includes a fixed frame 1, transmission shafts are arranged at both ends of the fixed frame 1, the two transmission shafts are connected through a transmission belt 2, a driving device 3 is fixedly installed at one end of the fixed frame 1, the driving device 3 is fixedly connected to one of the transmission shafts, a cleaning mechanism 7 is fixedly installed on the fixed frame 1 on one side of the driving device 3, a U-shaped block 6 and a control panel 4 are fixedly installed on the outside of the fixed frame 1, and a tensioning mechanism 5 is fixedly installed on the fixed frame 1 on one side of the control panel 4.

[0026] In the present application, the control panel 4 is used to control the start and stop of the driving device 3 and the electric push rod 505 , and the pressure sensor 504 is electrically connected to the control panel 4 .

[0027] Furthermore, movable grooves 101 are provided on both sides of one end of the fixed frame 1, and the tensioning mechanism 5 includes two connecting shafts 501, and the two connecting shafts 501 are fixedly connected to the two ends of the transmission shaft away from the driving device 3 through the movable grooves 101, and a bearing 502 is fixedly sleeved on the outside of each connecting shaft 501, and a fixed sleeve block 503 is fixedly connected to the outer surface of each bearing 502, and a pressure sensor 504 is fixedly connected to the side of each fixed sleeve block 503 close to the driving device 3, and electric push rods 505 are fixedly installed on both sides of the fixed frame 1, and the output end of the electric push rod 505 is fixedly connected to the pressure sensor 504.

[0028] In the present application, when the goods carried on the transmission belt 2 are heavier, the transmission belt 2 will be subjected to the tensile force in the process of transporting materials. If the tension of the transmission shaft is not adjusted properly, it will cause excessive stretching and wear of the transmission belt 2, thereby reducing the service life of the transmission belt 2. When the transmission belt 2 is over-stretched, the pressure sensor 504 receives the pressure and transmits the signal to the control panel 4. The control panel 4 controls the start of the two electric push rods 505, so that the electric push rods 505 drive the two connecting shafts 501 to move in the direction of eliminating the tensile force, thereby reducing the wear of the transmission belt 2; after the transmission belt 2 has been used for a long time, its inner wall will become thinner due to the wear of the two transmission shafts, which will cause the transmission belt 2 to be in a relaxed state, resulting in the problem of slipping and deviation of the transmission belt 2, thereby affecting the transportation efficiency of mining production. At this time, with the help of the two electric push rods 505, the two connecting shafts 501 are driven to move outward along the movable groove 101 to adjust the tension of the transmission belt 2.

[0029] Furthermore, the transmission belt 2 includes a base belt 201 , both ends of which are respectively sleeved on two transmission shafts, an oil-resistant rubber coating layer 202 is fixedly connected to the outer surface of the base belt 201 , and a wear-resistant layer 203 is fixedly connected to the outer surface of the oil-resistant rubber coating layer 202 .

[0030] In the present application, the provision of the wear-resistant layer 203 improves the wear resistance of the transmission belt 2, thereby increasing its service life.

[0031] Furthermore, the cleaning mechanism includes a connecting block 701 , a spherical groove 7011 is provided in the connecting block 701 , a rotating ball 702 is arranged in the spherical groove 7011 , a connecting plate 703 is fixedly connected to the upper surface of the rotating ball 702 , and a scraper 704 is fixedly connected to the lower surface of the connecting plate 703 .

[0032] In the present application, the rotating ball 702 is first rotated so that the connecting plate 703 is driven by the rotating ball 702 to be rotated to the top of the transmission belt 2. At this time, the scraper 704 just contacts the upper surface of the transmission belt 2. The transmission belt 2 is then driven to rotate by the driving device 3. Under the action of the scraper 704, the dust remaining on the transmission belt 2 is scraped off, thereby achieving a cleaning effect.

[0033] Furthermore, a sliding groove 7031 is provided at one end of the connecting plate 703 away from the rotating ball 702, and a movable block 705 is slidably connected in the sliding groove 7031. A pull rod 706 and a fixed rod 708 are fixedly connected on the upper and lower sides of the movable block 705 respectively. The upper end of the pull rod 706 extends to the top of the connecting plate 703, and the lower end of the fixed rod 708 extends to the bottom of the connecting plate 703. A spring 707 is sleeved on the outer surface of the pull rod 706 located in the sliding groove 7031, and both ends of the spring 707 are fixedly connected to one side of the movable block 705 and the inner wall of the sliding groove 7031 respectively. A mounting hole 102 is provided on the fixing frame 1 corresponding to the fixed rod 708, and the fixed rod 708 is adapted to the mounting hole 102.

[0034] In the present application, in order to improve the stability of the scraper 704, when the scraper 704 is rotated, the pull rod 706 is pulled upward and the connecting plate 703 is driven to rotate under the action of the rotating ball 702. At this time, the spring 707 is in a compressed state. When the scraper 704 rotates to just above the transmission belt 2, the pull rod 706 is slowly released, and the spring 707 is reset. Driven by the spring 707, the fixed rod 708 fixedly connected to the movable block 705 is driven to move toward the mounting hole 102 until it is inserted into the mounting hole 102, thereby fixing the connecting plate 703 and preventing the scraper 704 from shaking when cleaning the transmission belt 2.

[0035] Furthermore, a limiting rod 709 is fixedly connected to the outer side of one end of the connecting plate 703 away from the rotating ball 702 , and the limiting rod 709 is adapted to the U-shaped clamping block 6 .

[0036] In the present application, after the transmission belt 2 is cleaned, the pull rod 706 is pulled again, and then the connecting plate 703 is rotated 90 degrees clockwise with the rotating ball 702 as the center, and the connecting plate 703 is rotated to the outside of the fixed frame 1, and finally the limiting rod 709 is inserted into the U-shaped block 6 to limit the connecting plate 703 and prevent the connecting plate 703 from shaking under the action of the rotating ball 702.

[0037] The working principle of this utility model:

[0038] When in use, the goods to be transported are placed on the transmission belt 2, and the transmission belt 2 is driven to rotate by the driving device 3 to achieve the purpose of transportation. During the transportation process, when the goods carried on the transmission belt 2 are heavy, the transmission belt 2 will be subjected to the tensile force in the process of transporting materials, resulting in excessive stretching and wear of the transmission belt 2, thereby reducing the service life of the transmission belt 2. When the transmission belt 2 is over-stretched, the pressure sensor 504 receives the pressure and transmits the signal to the control panel 4, and the control panel 4 controls the start of the two electric push rods 505, so that the electric push rods 505 drive the two connecting shafts 501 to move in the direction of eliminating the tensile force, thereby reducing the wear of the transmission belt 2; in addition, after long-term use of the transmission belt 2, its inner wall will become thinner due to the wear of the two transmission shafts, which will cause the transmission belt 2 to be in a loose state, resulting in the problem of slipping and deviation of the transmission belt 2, thereby affecting the transportation efficiency of mining production. At this time, the two electric push rods 505 are used to drive the two connecting shafts 501 to move outward along the inner wall of the movable groove 101, so as to adjust the tension of the transmission belt 2 and ensure the normal transportation of the transmission belt 2;

[0039] After the goods are transported, it is necessary to clean the residual materials on the transmission belt 2. At this time, the connecting plate 703 stuck on the U-shaped block 6 is rotated with the rotating ball 702 as the center. During the rotation, the user pulls the pull rod 706 upwards and drives the connecting plate 703 to rotate. At this time, the spring 707 is compressed. When the connecting plate 703 rotates 90 degrees, the scraper 704 is just above the transmission belt 2. Then the pull rod 706 is slowly released, and the spring 707 is reset. Driven by the spring 707, the fixing rod 708 is driven to move toward the mounting hole 102 until it is inserted into the mounting hole 102, thereby fixing the connecting plate 703 and preventing the scraper 704 from shaking when cleaning the transmission belt 2. Finally, under the drive of the driving device 3, the transmission belt 2 is driven to rotate, and with the cooperation of the scraper 704, the cleaning purpose is achieved.

[0040] To sum up: this kind of transmission belt for mining production, through the setting of tensioning mechanism 5, not only effectively solves the problem of excessive tensile force caused by goods on the transmission belt 2, causing wear of the transmission belt 2 and reduced service life; it can also play a good tightening effect on the transmission belt 2, preventing it from slipping, deviation and the like due to excessive relaxation; through the setting of cleaning mechanism 7, it is convenient to clean the dust remaining on the transmission belt 2, avoiding the inconvenience of manual cleaning of the existing transmission belt 2, and improving the cleaning efficiency. In addition, under the action of U-shaped block 6, it can play a role in limiting and storing the connecting plate 703, so that the cleaning mechanism 7 is stored to a position where it does not affect the transmission belt 2 to transport goods.
