[0002] Tubular belt conveyors are a specialized type of belt conveyor developed based on trough-type belt conveyors. They can continuously and enclosedly transport a variety of loose materials, such as powders, granules, and lumps. They offer advantages such as environmental friendliness, continuous and enclosed conveying, a small turning radius, bidirectional transport, and cost savings. This makes tubular belt conveyors widely used in mines, power plants, ports, and other locations. The automated material limiting and pressing device for tubular belt conveyors, a crucial component, plays a crucial role in protecting the safe material conveying process. With the advancement of science and technology, the requirements for automated material limiting and pressing devices are becoming increasingly demanding. The original manual control of the material limiting and pressing device resulted in pipe expansion accidents when errors were large, and the material-limiting baffle was easily deformed by the impact of the material when conveying different types of materials, leading to downtime and a series of economic losses. In summary, an automated material limiting and pressing device for tubular belt conveyors was designed. Utility Model Content

[0025] Example:

[0026] like Figure 1-7 As shown, an automatic material limiting and pressing device for a tubular belt conveyor is arranged on the middle frame of the material receiving section at the tail end of the tubular belt conveyor, and is used to limit the material height on the material receiving section, and at the same time press the rubber belt 7 to prevent the belt from winding. It includes a frame 4, which is a steel structure frame. The upper part of the frame is arranged in a rectangular shape. An active servo electric cylinder 1 is provided on one of the long sides. The active servo electric cylinder 1 is electrically connected to the control device. Preferably, an active servo electric cylinder 1 is provided on both sides of the long side. They move synchronously, and their output ends are respectively connected to the two sides of the material limiting baffle 2. The control device uses a PLC, which can accurately control the extension and reciprocating length of the output end of the active servo electric cylinder 1, and accurately control the reciprocating motion of the material limiting baffle 2 in the vertical direction in real time according to demand, so as to adjust the height between the material limiting baffle 2 and the rubber belt 7, thereby accurately controlling the stacking height of the material on the rubber belt 7.

[0027] A slave servo cylinder 3 is provided on the long side opposite to the active servo cylinder 1 on the frame 4. The active servo cylinder 1 is electrically connected to the slave servo cylinder 3. The base of the slave servo cylinder 3 is hinged to the frame 4 and can rotate relative to the frame 4. The telescopic output end of the slave servo cylinder 3 is also hinged to the material limit baffle 2. While the active servo cylinder 1 drives the material limit baffle 2 to telescopically move up and down, the slave servo cylinder 3 also telescopically moves to ensure that the material limit baffle 2 moves up and down normally. The slave servo cylinder 3 itself forms a triangular support with the frame 4 and the material limit baffle 2, thereby increasing the strength of the material limit baffle 2 and being able to withstand stronger material impact forces, thereby avoiding deformation of the material limit baffle 2 caused by the impact of the material. A program can be set in the PLC to control the coordinated movement between the active servo cylinder 1 and the slave servo cylinder 3 through electrical connection signals, thereby driving the material limit baffle 2 to move stably. The hinged connection structure can be understood by those skilled in the art and will not be described in detail here.

[0028] The material limit baffle 2 is a curved steel plate that matches the cross-sectional shape of the rubber belt 7. During vertical movement, it avoids contact with the inclined surface of the rubber belt 7, thereby ensuring that the material accumulation height is controlled. This prevents interference between the two sides of the material limit baffle 2 and the inclined surfaces of the rubber belt 7 when a lower material height is required.

[0029] The belt pressing device includes a belt pressing channel steel 5 and a belt pressing roller 6. The belt pressing channel steel 5 is set on one of the long sides of the frame 4. It is provided with through holes at both ends. On both sides of the frame 4, a number of threaded holes are evenly arranged in the height direction. According to actual needs, the through holes of the belt pressing channel steel 5 are aligned with the threaded holes of the corresponding height on the frame 4, and then fixed by a bolt structure to achieve the height adjustment of the belt pressing channel steel 5. Two belt pressing rollers 6 are provided, which are connected to both sides of the belt pressing channel steel 5 through connecting plates. Preferably, the belt pressing roller 6 is fixedly connected to the connecting plate in a vertical direction, such as Figure 7 As shown, two parallel waist holes are set on the connecting plate, and two identical parallel waist holes are also set on both sides of the belt pressing channel steel 5. Adjusting the angle of the connecting plate relative to the belt pressing channel steel 5 can adjust the angle of the belt pressing roller 6, so that it is in parallel contact with the rubber belt 7 to achieve the belt pressing function. After the angle is adjusted, the corresponding waist holes are directly fixed to each other through the bolt structure. The height adjustment of the belt pressing channel steel 5 and the angle adjustment of the belt pressing roller 6 can adapt to the belt pressing function of rubber belts 7 of different shapes, with wide adaptability.

[0030] A material flow detection device 8 is provided on the material limiting baffle 2, which is preferably an alarm and some kind of light sensor or distance sensor. When the tubular belt conveyor is blocked during operation, the material covers the light sensor or distance sensor, causing it to send an electrical signal to the alarm device to alert the staff of the blockage and clean it up in time.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
