Description

Technical Field

[0001] The utility model belongs to the technical field of quartz sand conveying, and specifically relates to a belt conveyor structure. Background Art

[0002] Quartz sand needs to go through multiple processes such as cleaning, crushing, and air drying during production. When two adjacent processes are carried out, the quartz sand needs to be transported by a belt conveyor;

[0003] Since the production of quartz sand is usually carried out in the open air, in order to reduce the quartz sand blowing on the upper side of the belt conveyor during strong winds, a wind shield covering the quartz sand needs to be installed on the outside of the belt conveyor;

[0004] However, since one end of the belt conveyor is higher, it is difficult to install the wind shield. In order to reduce the installation difficulty, a Chinese patent with the authorization announcement number CN208603183U discloses a wind-proof belt conveyor for quartz sand production, which solves the problem that when installing the wind shield for most wind-proof belt conveyors for quartz sand production, the wind shield needs to be lifted to a high place and fixed with screws, which is troublesome to operate and brings inconvenience to the installation of the wind shield.

[0005] However, during installation, the wind shield connected to it is pulled by the wire rope to adjust the position of the wind shield. After the wind shield is moved, the wire rope is connected to another wind shield. During this process, the user needs to lift the wind shield installed on the belt conveyor, resulting in the user needing to bear more weight of the wind shield during operation. Utility Model Content

[0006] The purpose of the utility model is to provide a belt conveyor structure, which can reduce the difficulty of installing the windshield and effectively reduce the weight of the windshield borne by the user when installing the windshield.

[0009] The slides inside the two slide grooves are opposite to each other as a group, and the upper end of the slide groove is a fixed part extending to the upper side of the guide rail through the through groove. The fixed part of the slide grooves in the same group is detachably fixedly connected with a windshield covering the upper side of the belt body.

[0010] Furthermore, the axial center distance between two adjacent wind shields is the same as the axial center distance between two adjacent slides.

[0011] Furthermore, a plurality of receiving grooves located at the lower side of the slide groove and connected to the slide groove are provided inside the guide rail, an action group is installed inside the receiving groove, and a protrusion that can enter the slide groove is installed on the action group.

[0012] Furthermore, the action group includes a return spring installed inside the storage groove, and the upper part of the front end of the protrusion is provided with an inclined surface.

[0013] Furthermore, an electromagnet is fixedly connected to the interior of the storage slot, the material of the protrusion is iron, and the electromagnet magnetically adsorbs the protrusion when power is supplied.

[0014] Furthermore, a plurality of moving wheels are fixedly connected to the lower side of the slide.

[0015] The technical effects achieved by this utility model are:

[0016] The practical belt conveyor structure can complete the installation of the windshield on the ground by pulling multiple groups of slides through pull ropes, and there is no need to climb high to operate, thereby reducing the difficulty of installation; when installing the windshield, the user only needs to bear the weight of one of the windshields, and the weight of the remaining windshields is borne by the traction mechanism, thereby effectively reducing the weight of the windshield borne by the user when installing the windshield.

[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0024] like Figure 1 As shown, a belt conveyor structure includes a base frame 1 and two brackets 2 fixedly connected to the upper side of the base frame 1, the rear ends of the two brackets 2 are inclined upward, and two driving rollers 3 are rotatably connected between the two brackets 2. The outer sides of the two driving rollers 3 are equipped with belt bodies 4. When quartz sand falls on the upper side of the belt body 4, the belt body 4 and the quartz sand can be moved by the rotation of the driving rollers 3 to complete the transportation of the quartz sand. In order to drive the driving rollers 3 to rotate, a motor drive group 5 connected to one of the driving rollers 3 is fixedly connected to the base frame 1. After the motor drive group 5 is started, it will drive the driving roller 3 connected to it to rotate.

[0025] See also Figure 1-2 As shown, the core of the technical solution is that the two brackets 2 are fixedly connected with a guide rail 7, the guide rail 7 is provided with a slide groove 8, the front end of the slide groove 8 is provided with a rack entry, the upper end of the slide groove 8 is provided with a through groove, the inside of the slide groove 8 is slidably connected with a plurality of slides 9 entering the inside of the slide groove 8 through the rack entry, the rear ends of the two brackets 2 are fixedly connected with a traction mechanism 11, and the traction mechanism 11 is equipped with a pull rope 10 connected with a plurality of slides 9, and the traction mechanism 11 winds up the pull rope 10, so that the plurality of slides 9 can be pulled synchronously;

[0026] The slides 9 inside the two slide grooves 8 are opposite to each other as a group, and the upper ends of the slide grooves 8 are fixed parts extending to the upper side of the guide rail 7 through the through grooves. The fixed parts of the same group of slide grooves 8 are detachably fixedly connected with a windshield 6 covering the upper side of the belt body 4, and the fixing method is preferably screw connection or clamping. The windshield 6 can reduce the phenomenon of quartz sand on the upper side of the belt body 4 being blown away by the wind.

[0027] Here, the axial center distance between two adjacent windshields 6 is the same as the axial center distance between two adjacent slides 9 , so that the two adjacent windshields 6 fit tightly when they are installed on two adjacent slides 9 .

[0028] At this time, when the windshield 6 is installed, the two slides 9 of the same group are installed into the interior of the slide groove 8, and then a windshield 6 is installed on the fixed part of the two slide grooves 8. After the installation is completed, the traction mechanism 11 is started, and the slide 9 and the windshield 6 are driven to move by the pull rope 10 until the next group of two slides 9 are installed into the interior of the slide groove 8. Repeat the above steps until all the windshields 6 are installed. During this process, the user only needs to bear the weight of one of the windshields 6, and the weight of the remaining windshields 6 is borne by the traction mechanism 11, thereby effectively reducing the weight of the windshield 6 borne by the user when installing the windshield 6.

[0029] like Figure 2-3 As shown, in order to reduce the pulling force requirement of the traction mechanism 11, a plurality of moving wheels 12 are fixedly connected to the lower side of the slide 9. The moving wheels 12 can move inside the slide groove 8 by rotating, thereby reducing the friction force when the slide 9 moves.

[0030] In addition, the guide rail 7 is provided with a plurality of storage grooves 13 located at the lower side of the slide groove 8 and connected to the slide groove 8. An action group is installed inside the storage groove 13, and a protrusion 16 that can enter the slide groove 8 is installed on the action group. The slide 9 can be limited by the protrusion 16 to provide support force for the slide 9, thereby further reducing the pulling force requirement of the traction mechanism 11 and improving the stability of the wind shield 6 after installation.

[0031] like Figure 3-4 As shown, the action group includes a return spring 15 installed inside the storage groove 13, and a slope 17 is provided on the upper part of the front end of the protrusion 16. At this time, when the rear end of the guide rail 7 on the slide 9 moves, it will contact the slope 17, and the slide 9 will press the slope 17 to allow the protrusion 16 to enter the interior of the storage groove 13. When the slide 9 and the protrusion 16 are separated, the return spring 15 will drive the protrusion 16 to reset, thereby completing the limitation of the slide 9.

[0032] At the same time, the inside of the storage groove 13 is also fixedly connected to an electromagnet 14, and the material of the protrusion 16 is iron. When the electromagnet 14 is energized, the protrusion 16 is magnetically attracted to pull the protrusion 16 into the inside of the storage groove 13, thereby automatically releasing the limit of the slide 9 by the protrusion 16. At this time, the pull rope 10 can be unwound by the traction mechanism 11, so that the slide 9 drives the wind shield 6 to slide down, thereby making it relatively easy to disassemble.

[0033] The working principle of the utility model is as follows: when installing the wind shield 6, two slides 9 of the same group are installed into the interior of the slide slot 8, and then one wind shield 6 is installed on the fixed part of the two slide slots 8. After the installation is completed, the traction mechanism 11 is started, and the slide 9 and the wind shield 6 are driven to move by the pull rope 10 until the next group of two slides 9 are installed into the interior of the slide slot 8, and the above steps are repeated until all wind shields 6 are installed;

[0034] When the slide 9 moves, it will contact the inclined surface 17, and the slide 9 will press the inclined surface 17, so that the protrusion 16 enters the interior of the storage groove 13. When the slide 9 and the protrusion 16 are separated, the return spring 15 will drive the protrusion 16 to reset, completing the limit of the slide 9;

[0035] When the wind shield 6 is to be disassembled, the limit imposed by the protrusion 16 on the slide 9 is automatically released by the protrusion 16, and then the pull rope 10 is unwound by the traction mechanism 11, allowing the slide 9 to drive the wind shield 6 to slide down. When the wind shield 6 moves to the bottom, the wind shield 6 can be disassembled.

[0036] In summary, in the present technical solution, multiple groups of slides 9 are pulled by pull ropes 10, so that the installation of the windshield 6 can be completed on the ground, without the need to climb high to perform the operation, thereby reducing the difficulty of installation. When installing the windshield 6, the user only needs to bear the weight of one of the windshields 6, and the weight of the remaining windshields 6 is borne by the traction mechanism 11, thereby effectively reducing the weight of the windshield 6 borne by the user when installing the windshield 6.

[0037] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
