Abstract
Description
Technical Field
[0001] This utility model relates to the field of building material testing technology, specifically a splitting test device for recycled coal gangue mixture. Background Technology
[0002] Coal gangue is a solid waste generated during coal mining and washing. It is a dark gray rock with a low carbon content and harder than coal, which is associated with coal seams during coal formation. It includes gangue from tunnel excavation, gangue extracted from the roof, floor, and interlayers during mining, and gangue removed during coal washing. Its main components are Al2O3 and SiO2, and it also contains varying amounts of Fe2O3, CaO, MgO, Na2O, K2O, P2O5, SO3, and trace amounts of rare elements (gallium, vanadium, titanium, cobalt).
[0003] Coal gangue contains more than 80% silicon dioxide, ferric oxide, and aluminum oxide. It is a natural clay raw material that can be used to produce various special-purpose cements for construction, such as ordinary silicate cement, special cement, and clinker cement, thus reducing the need to dig up arable land.
[0004] When using coal gangue as a building material, its strength needs to be tested to eliminate potential safety hazards. Existing splitting devices often use protective covers to surround the device to prevent debris from flying, which, while suppressing debris, results in slow material discharge due to the enclosure structure. Therefore, we propose a splitting test device for recycled coal gangue mixtures. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a splitting test device for recycled coal gangue mixture, which automatically cleans and discharges the broken coal gangue, improves the discharge efficiency, reduces the safety hazards of manual labor, and can effectively solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a splitting test device for recycled coal gangue mixture, comprising a base plate, an experimental box fixedly connected to the middle of the upper surface of the base plate, a through groove opened on the front surface of the experimental box, a push plate horizontally arranged inside the experimental box, a push plate rotatably connected to the front end of a screw through a bearing at the middle of the rear surface of the push plate, the screw being threadedly connected to a screw hole opened on the rear surface of the experimental box, the rear end of the screw extending through the screw hole to the outer rear side of the experimental box, and being movably connected to a square plate through a bearing, the left and right sides of the front surface of the square plate being slidably connected to limiting rods through sliding holes, the front ends of the two limiting rods being fixedly connected to corresponding positions on the rear surface of the experimental box, and a splitting mechanism being arranged on the upper inner side of the experimental box.
[0007] The design incorporates an experimental box for testing, which blocks debris to prevent scattering. A pusher plate is also included to push out the crushed coal gangue recycled mixture, thus automatically cleaning up the waste. During cleaning, the screw rotates, which in turn moves the pusher plate to push out the crushed coal gangue recycled mixture from the experimental box.
[0008] Furthermore, the splitting mechanism includes a mounting frame, which is fixedly connected to the upper surface of the experimental box. The lower surface of the mounting frame is fixedly connected to a lower pressure plate via a hydraulic rod. The input end of the hydraulic rod is electrically connected to the output end of an external power supply via an external control switch group. The lower end of the lower pressure plate is fixedly connected to the upper end of a round rod at equal intervals. The lower end of each round rod extends through a round hole opened at a corresponding position on the experimental box and extends into the interior of the experimental box, and is fixedly connected to the corresponding position on the upper surface of the splitting blade.
[0009] The design incorporates a splitting blade to perform splitting tests on recycled coal gangue mixtures, thereby assessing the strength of the mixtures. During testing, an external control switch group controls the hydraulic rod, which in turn moves the lower pressure plate downwards, causing the splitting blade to press down and perform the splitting operation.
[0010] Furthermore, the splitting mechanism also includes a slide rod, which is slidably connected to a circular hole at a corresponding position on the baffle. The upper end of the slide rod passes through the circular hole and is fixedly connected to the horizontal plate. The lower surface of the horizontal plate is fixedly connected to the movable plate by a spring, and the front end of the movable plate is fixedly connected to the baffle.
[0011] The design incorporates a baffle to block the channel during splitting operations, preventing debris from splashing out of the channel and enhancing safety. When the pressure plate moves down, it causes the baffle to move downward as well.
[0012] Furthermore, the test device also includes a motor, with the rear end of the square plate fixedly connected to the motor. The output shaft of the motor passes through a circular hole in the square plate and is fixedly connected to the rear end of the screw. The input end of the motor is electrically connected to the output end of an external power supply through an external control switch group.
[0013] When the control screw rotates, the motor is controlled by an external control switch group, which in turn drives the screw to rotate.
[0014] Furthermore, the experimental device also includes a discharge trough, with the discharge trough fixedly connected to the lower part of the front surface of the experimental box located in the through groove, and a feed inlet opened at the lower part of the right side surface of the experimental box, with the right side port of the feed inlet fixedly connected to the feed trough.
[0015] The design incorporates a discharge chute, allowing waste materials to slide off at an angle, thus saving manpower.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This splitting test device for recycled coal gangue mixture has the following advantages:
[0017] 1. Design an experimental box to conduct tests within the box, thereby blocking debris and preventing it from splashing.

When cleaning, the screw 13 is controlled to rotate, which drives the push plate 12 to move, thus pushing out the crushed coal gangue recycled mixture from the experimental box 2.
[0028] The splitting mechanism includes a mounting frame 3. The mounting frame 3 is fixedly connected to the upper surface of the experimental box 2. The lower surface of the mounting frame 3 is fixedly connected to the lower pressure plate 5 via a hydraulic rod 4. The input end of the hydraulic rod 4 is electrically connected to the output end of an external power supply via an external control switch group.

When the lower pressure plate 5 moves down, it drives the baffle 11 to move down, thereby blocking the through chute. After the experiment is completed, the lower pressure plate moves up to reset. Then, the motor 14 is controlled by the external control switch group to work, thereby driving the screw 13 to rotate, which in turn drives the push plate 12 to move, thereby pushing out the crushed recycled coal gangue mixture in the experimental box 2.
