[0024] The structure of the present invention will be further described below with reference to the accompanying drawings and through examples. It should be noted that the present examples are descriptive rather than restrictive.
[0025] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this utility model belongs.
[0026] A cantilever stacker anti-spill device, see Figures 1-6The invention mainly includes a spillage prevention device for the tail car stacking belt 1, a spillage prevention device for the tail car hopper 5, and a spillage prevention device for the cantilever belt 8. The spillage prevention device for the tail car stacking belt mainly consists of a device to prevent the tail car stacking belt from deviating 2 and a device to prevent the tail car stacking belt from shaking significantly 3. The spillage prevention device for the tail car hopper mainly consists of an expandable hopper 5 and a buffer guide baffle 6 that controls the drop point. The cantilever belt 8 anti-spillage device is mainly composed of a cantilever belt deviation prevention device 9, a belt return material spillage prevention device 10 and a belt return spillage receiving device 11. Each device is relatively independent and interconnected. The anti-spillage device is used to control the spillage of possible parts of the cantilever stacker where spillage is possible, which greatly reduces the spillage of the cantilever stacker and provides effective technical support in equipment environmental management. While effectively controlling the pollution of the surrounding environment to the spilled materials, it reduces the frequency of cleaning operations of the cantilever stacker cleaning personnel. On the premise of saving a lot of manpower, the level of equipment environmental management has been further improved.
[0027] The above-mentioned tail car stacking belt anti-spillage device can prevent the tail car stacking belt from running off the track and causing uneven heights on both sides of the belt, spilling of materials from the lower side, and the large material movement at the climbing point where the tail car stacking belt connects with the tail car of the cantilever stacker, which flattens the concave part of the belt and causes materials to spill from both sides of the tail car stacking belt. The above-mentioned tail car lower hopper anti-spillage device can prevent the tail car lower hopper inlet from having more material than the outlet, causing material to block the hopper and overflow, spilling of materials due to material characteristics, spilling of materials due to leakage from the gap between the tail car lower hopper outlet guide trough and the cantilever belt, and the deviation of the cantilever belt due to the misalignment of the material drop point. The above-mentioned cantilever belt anti-spillage device can prevent the cantilever belt from running off the track and causing uneven heights on both sides of the belt, spilling of materials from the lower side, spilling of attached materials along the return belt, and spilling of materials within the cantilever rotation range.
[0028] In the embodiments, see Figure 1 and Figure 2The device 2 for preventing the tail car stacking belt from deviating comprises a bottom support plate 2-6 and two sets of deviation limiting components symmetrically mounted on the bottom support plate. The two ends of the bottom support plate are fixedly connected to the belt support. Each set of deviation limiting components comprises a roller support 2-1, a trough support 2-2, a flat support 2-3, and an upper stop roller 2-4. The roller support is composed of a bottom edge and an outer inclined side edge. The flat support is rotatably mounted on the inner side of the bottom edge, the trough support is rotatably mounted on the inner side of the outer inclined side edge, and the upper stop roller is inwardly suspended and rotatably mounted on the upper end of the outer inclined side edge. A rotating shaft is provided at the lower end of the roller support of the two sets of deviation limiting components. The rotating shaft is vertically fixedly connected to the bottom support plate through a bearing. A sprocket is fixedly mounted at the lower end of the two rotating shafts. The two sprockets are connected by a chain to form a deviation adjuster 2-5. At least one set of device for preventing the tail car stacking belt from deviating is installed at each part of the tail car stacking belt that is prone to deviation. The anti-tail car stacking belt deviation device 2 runs with the tail car stacking belt 1. When the belt deviates, the belt running position can be adjusted by the device's deviation force to ensure that the belt runs stably in the normal working position.
[0029] In the embodiments, see Figure 1 and Figure 3 The device for preventing the tail-car stacking belt from vibrating significantly comprises a pressure roller mounting frame 3-1, a bearing seat 3-2, and a pressure roller assembly. The pressure roller assembly comprises a central shaft 3-3 and a plurality of pressure rollers 3-4 fixedly mounted parallel to the central shaft at intervals. The attached figure shows four pressure rollers. The pressure roller mounting frame 3-1 is a portal frame, with two bearing seats fixedly mounted on the inner sides of the columns on either side of the frame and arranged coaxially. The ends of the central shaft are rotatably supported on the bearing seats on both sides by bearings. The bottom of the frame is mounted and fixed to both sides of the tail-car stacking belt conveyor 1 by means of fixing bolts. The entire frame spans the tail-car stacking belt 1, so that the pressure roller assembly mounted on the frame is located above the stacking belt 1 at the starting point of the tail climbing of the cantilever stacker. When the belt vibrates upward and hits the pressure roller, it quickly falls back. This device for preventing the tail-car stacking belt from vibrating significantly can effectively control the vertical vibration range of the stacking belt at the starting point of the tail climbing and the degree of flattening of the vibration in the belt depression.
[0030] In the embodiments, see Figure 1 and Figure 4 The expanded hopper 5 of the tail car adopts a hopper with a volume and a discharge port 5-2 that are larger than the original design, and replaces the original design hopper as a whole. While effectively ensuring that the material volume of the discharge port 5-2 of the tail car hopper is always greater than the material volume of the feed port 5-1, it reduces the possibility of material blockage and overflow of the hopper due to accumulation of sticky materials on the hopper wall or the discharge port.
[0031] In the embodiments, see Figure 1 and Figure 4 The tail car hopper buffer guide baffle 6 is installed in the hopper
[0032] Located below the throwing drum and opposite the discharge port 5-2 of the lower hopper, the buffer guide baffle of the tail car lower hopper is a downwardly inclined baffle facing the discharge port. It extends into the guide chute 7 of the tail car lower hopper, with its lower end extending close to the cantilever belt bearing surface 8-1. It buffers, stops, and guides the material 4 thrown from the tail car stacking belt 1, smoothly conveying the material 4 to the center of the cantilever belt 8 in the direction of the buffer guide baffle 6, preventing the material 4 from deviating from the cantilever belt and leaking out of the gap in the guide chute 7.
[0033] In the embodiments, see Figure 1 The anti-cantilever belt deviation device adopts the same structural form as the anti-tail car stacking belt deviation device, and the anti-cantilever belt deviation device 9 is installed at the position where the cantilever belt 8 is prone to deviation.
[0034] In the embodiments, see Figure 1 and Figure 5 The device for preventing return belt material from spilling includes three belt cleaners: a first return belt cleaner 10-1, a second return belt cleaner 10-2 and a third return belt cleaner 10-3. The first return belt cleaner 10-1 is installed at the starting position of the return belt surface 8-2 of the cantilever belt head, and the second return belt cleaner 10-2 and the third return belt cleaner 10-3 are installed below the return belt surface 8-2 of the cantilever belt head. The three belt cleaners can effectively remove the adhered materials on the return belt 8-2 surface, and can remove most of the adhered materials and discharge the removed materials onto the stockpile.
[0035] In the embodiments, see Figure 1 and Figure 6The belt return spilled material receiving device includes a front receiving trough 11-1, a rear receiving trough 11-2, a receiving and recycling hopper 11-3, and a fixed connecting frame 11-4. The front receiving trough, the rear receiving trough, and the receiving and recycling hopper are all welded and installed directly below the cantilever belt 8 through the fixed connecting frame 11-4. The spilled material centralized receiving device 11 is divided into a front receiving trough 11-1 and a rear receiving trough 11-2 with the middle part of the cantilever belt 8 as the installation node. The front receiving trough 11-1 is installed at an angle of 10 degrees to the middle installation node to ensure that the spilled materials received on the front receiving trough 11-1 will not slide out of the receiving device due to the tilt angle. Only when the cantilever stacker performs a downward movement will the materials received on the front receiving trough slide out of the receiving device and the materials will be discharged to the storage stack. The rear chute 11-2 is installed at a 15° angle to the central mounting node. Due to the tilt, some spilled material collected by the receiving device will slide into the device recovery hopper 11-3 connected to the rear chute. When the cantilever stacker descends, spilled material that falls into the front chute is channeled through the front port of the front chute onto the stockpile. When the cantilever stacker ascends, any remaining material collected by the rear chute slides into the device recovery hopper 11-3. Removal personnel only need to centrally clean the spilled material collected in the device recovery hopper 11-3. This reduces the number of personnel and time required for cleaning, effectively preventing spilled material from reaching the ground during cantilever belt operations. This achieves the goal of centralized collection and disposal of spilled material from the cantilever belt.

Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
