Description

Technical Field

[0001] This invention relates to belt conveyors, and more specifically, to a semi-fixed belt conveyor head station. Background Technology

[0002] Large belt conveyors generally consist of a head section, a drive station section, a tail section, and an intermediate frame section. For example, Chinese patent CN201210347908.0 provides a movable belt conveyor head station. The main steel structure adopts a gantry-type structure with clearance. A sliding rail is provided on the frame, a power element is located at one end of the frame, and a working hinge point and a transport hinge point are located at the other end of the frame. The transport hinge point is located above the working hinge point, and a rotating hinge shaft is provided between the main steel structure and the frame. This invention utilizes the power element to perform a small-range rotation of the frame and belt tensioning device to allow the transfer vehicle to enter the bottom of the head station for transfer, avoiding the unsafe factors of tilting the belt conveyor, head station body, head hopper, electrical room, etc. during transfer. In existing conveyor head stations like the one described above, the head often has a hopper. During long-term material transport, highly viscous materials tend to stick to the inner wall of the hopper, and if not cleaned for a long time, they can easily clump together, leading to poor material discharge. Summary of the Invention

[0003] The purpose of this invention is to provide a semi-fixed belt conveyor head station, which solves the problem in the prior art where the head of the conveyor head station is often equipped with a hopper. During long-term transportation of materials, highly viscous materials tend to stick to the inner wall of the hopper, and if not cleaned for a long time, they tend to clump together, leading to poor material discharge.

[0004] To achieve the above objectives, the present invention provides a semi-fixed belt conveyor head station, the semi-fixed belt conveyor head station including a main body, one end of the main body is provided with a hopper part, the hopper part includes a discharge funnel, each side of the discharge funnel is respectively formed with a horizontal groove and a vertical groove connected to the horizontal groove, a scraper is provided in the horizontal groove, a sealing strip connected to the scraper is provided in the vertical groove, a drive rod is connected to the scraper, a movable frame is provided on the outer side of the discharge funnel that can be moved up and down, a ring is rotatably provided on the movable frame, one end of the crank is hinged to the ring, and the other end is hinged to the drive rod.

[0005] Preferably, the movable frame is provided with a sliding corner seat, which can be movably engaged with the corner of the feeding funnel.

[0006] Preferably, the inner wall of the ring is formed with an internal gear structure;

[0007] A motor is mounted on the sliding angle seat, and a drive gear is coaxially connected to the output shaft of the motor. The drive gear meshes with the internal gear structure.

[0008] Preferably, the sliding corner seat is provided with an arc-shaped sliding track, and the ring is rotatably engaged in the arc-shaped sliding track.

[0009] Preferably, the inner wall of the arc-shaped sliding track is rotatably provided with a plurality of rollers, and the rollers are in contact with the side of the ring.

[0010] Preferably, the feeding hopper is provided with a support, and the support is provided with a cylinder, the output shaft of the cylinder being connected to the movable frame.

[0011] Preferably, the upper end of the feeding funnel extends outward to form an installation part.

[0012] Preferably, the scraper and the sealing strip are fitted with rubber sleeves.

[0013] This invention provides a semi-fixed belt conveyor head station, comprising a main body, with a hopper section at one end of the main body. The hopper section includes a discharge funnel, each side of which has a horizontal groove and a vertical groove communicating with the horizontal groove. A scraper is disposed in the horizontal groove, and a sealing strip connected to the scraper is disposed in the vertical groove. A drive rod is connected to the scraper. A movable frame is disposed on the outer side of the discharge funnel, which is vertically movable. A ring is rotatably disposed on the movable frame, with one end of a crank hinged to the ring and the other end hinged to the drive rod. In the initial state... The scraper and sealing strip block the horizontal and vertical grooves to prevent material leakage during normal feeding. When it is necessary to clean the inner wall of the feeding hopper, the ring is rotated, which drives the drive rod through the crank to move, so that the scraper and sealing strip extend into the inside of the feeding hopper. The ring is moved downward by the movable frame, so that the drive rod moves in the vertical groove. The scraper scrapes and cleans the inner wall of the feeding hopper. This solves the problem in the existing technology of conveyor head stations, which are often equipped with hoppers. During long-term transportation of materials, highly viscous materials tend to stick to the inner wall of the hopper. If not cleaned for a long time, they will easily clump together and cause poor feeding.

The hopper 2 includes a discharge funnel 3. Each side of the discharge funnel 3 is respectively formed with a horizontal groove 5 and a vertical groove 4 connected to the horizontal groove 5. A scraper 7 is provided in the horizontal groove 5. A sealing strip 6 connected to the scraper 7 is provided in the vertical groove 4. A drive rod 14 is connected to the scraper 7. A movable frame 9 is provided on the outer side of the discharge funnel 3, which can be moved up and down. A ring 13 is rotatably provided on the movable frame 9. One end of a crank 15 is hinged to the ring 13, and the other end is hinged to the drive rod 14. In its initial state, the scraper and sealing strip block the horizontal and vertical grooves to prevent material leakage during normal feeding.
