Description

Technical Field

[0001] The invention belongs to the technical field of mine paste filling equipment, and in particular relates to an anti-clogging bucket cone for mine paste filling aggregates. Background Art

[0002] The aggregates for paste filling in mines are usually metered and batched in a conical hopper with a bucket cone. The maximum particle size of the aggregate is less than 15mm, and the aggregate particles are very easy to bite into an arch bridge, resulting in poor discharge. Traditional processes usually use compressed air injection, external vibration motor vibration, and oil cylinder telescopic tamping to break the arch and assist flow. Due to the large changes in the raw material composition and the deadweight pressure of the material level, the arch bridge position and height are not fixed, and the fixed injection point is prone to misalignment and failure, affecting the smooth flow of the downstream process; the arch breaking effect of the external vibration motor method is greatly affected by the thickness of the wall material, and there are high energy consumption, fatigue damage to the hopper wall material, and dense vibration of the material; the cylinder piston rod telescopic movement along the axial single dimension breaks the arch, which cannot adapt to the changes in the position and height of the arch bridge. The piston rod is too long and is easily affected by the material pressure and scouring deformation and instability, and requires an additional power source. The arch bridge of the hopper material has become a stubborn problem of poor material flow. Summary of the invention

[0014] The flow-aiding method based on the above-mentioned mining paste filling aggregate anti-clogging bucket cone includes the following steps: (1) Make the anti-clogging bucket cone of the mining paste filling aggregate in the initial state: make the horizontal straight line passing through the center point of the C pin coincide with the horizontal straight line passing through the center point of the fixed transmission shaft, the acute angle between the B pin, the C pin and the fixed transmission shaft is 30°, and the piston rod of the drive cylinder is fully retracted; (2) The piston rod of the driving cylinder is extended. The end of the piston rod pushes the torque increasing connecting rod through the E pin shaft to drive the fixed transmission shaft to rotate 30°. The fixed transmission shaft drives the rotary plate to rotate synchronously. The rotary plate drives the C pin shaft to rotate synchronously. The C pin shaft drives the range extending connecting rod to move. The range extending connecting rod drives the range extending ear seat and the rotary rake arm to rotate around the A pin shaft through the B pin shaft. The rotary rake arm swings outward to the maximum angle. (3) The piston rod of the driving cylinder is extended to the maximum extension length. The end of the piston rod pushes the torque increasing connecting rod through the E pin shaft to drive the fixed transmission shaft to continue to rotate 30° on the basis of step (2). The fixed transmission shaft drives the rotating plate to rotate synchronously. The rotating plate drives the C pin shaft to rotate synchronously. The C pin shaft drives the range extending connecting rod to move. The range extending connecting rod drives the range extending ear seat and the rotary rake arm to rotate in the opposite direction around the A pin shaft through the B pin shaft. The rotary rake arm swings in the opposite direction to the initial state position. (4) The driving cylinder retracts the piston rod. The end of the piston rod pushes the torque increasing connecting rod through the E pin shaft to drive the fixed transmission shaft to rotate 30° in the opposite direction based on step (3). The fixed transmission shaft drives the rotating plate to rotate in the opposite direction synchronously. The fixed rotating plate drives the C pin shaft to rotate in the opposite direction synchronously. The C pin shaft drives the range extending connecting rod to move. The range extending connecting rod drives the range extending ear seat and the rotary rake arm to rotate around the A pin shaft through the B pin shaft. The rotary rake arm swings outward to the maximum angle. (5) The driving cylinder completely retracts the piston rod. The end of the piston rod pushes the torque increasing connecting rod through the E pin shaft to drive the fixed transmission shaft to rotate 30° in the opposite direction based on step (4). The fixed transmission shaft drives the rotating plate to rotate in the opposite direction synchronously. The rotating plate drives the C pin shaft to rotate in the opposite direction synchronously. The C pin shaft drives the range extending connecting rod to move. The range extending connecting rod drives the range extending ear seat and the rotating rake arm to rotate around the A pin shaft through the B pin shaft. The rotating rake arm swings in the opposite direction until it is parallel to the rectangular flange plane and returns to the initial state of step (1). (6) Repeat steps (1) to (5), and the rotary rake wall swings repeatedly to destroy the material bridge arch, thereby achieving continuous flow assistance.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. An isolation plate is provided on the upper part of the bucket cone, which divides the bucket cone into two sections, the upper section is divided by the isolation plate to form four identical areas with vertical side walls, eliminating the condition for high-position powder in the upper section of the bucket cone to form a bridge arch at the axis; the bucket cone wall is the arch foot foundation section of the material arch bridge, and the rotary rake wall is set along the length direction of the bucket cone wall generatrix, with a length covering the upper and lower ends. By rotating and swinging into the bucket cone, the powder bridge arch foundation is destroyed. It has a dual flow-aiding function and is highly adaptable to material changes.

[0016] 2. The rotation center of the rotary rake arm is located at the upper end, and the swing displacement of the lower end is greater than that of the upper end. While destroying the compacted material at the lower end, it further activates the material near the upper end, which is conducive to the continuous and stable flow of bucket cone powder to the lower outlet.

[0017] 3. The rotary harrow wall adopts a rectangular long thin plate structure. The thin plate plane is parallel to the direction of the rotary harrow wall, which is conducive to cutting the powder bridge arch and has low energy consumption.

[0018] 4. It is equipped with a range-extending ear seat and a range-extending connecting rod, which can be configured to adjust the swing displacement of the lower end of the rotary rake arm 2 according to the material characteristics and the size of the inclined wall of the bin, and has strong adaptability to the bin structure.

[0019] 5. A torsion-increasing connecting rod is provided, which can increase the torque and reduce the thrust of the driving cylinder by lengthening the torsion-increasing connecting rod, and has low energy consumption.

[0020] 6. There is a rotating disc. The gap between the rotating disc and the disc shell remains unchanged during the rotation process, which prevents the incremental material from entering the gap space and causing jamming, and has high reliability.

[0021] 7. The stroke of the drive cylinder can be adjusted to change the rotation angle of the turntable. One movement of the drive cylinder can achieve the adjustment function of swinging the rotary rake arm once or twice.

[0022] 8. The drive cylinder can adopt a telescopic drive cylinder to drive the transmission shaft together with the torsion-increasing connecting rod, or a rotary drive cylinder can be adopted to directly drive the transmission shaft, which is convenient for selection according to the material load characteristics to achieve low-consumption drive.

[0023] In conclusion, the present invention effectively solves the problems of poor material discharge and poor flow-aiding effect of the existing aggregate bucket cone. BRIEF DESCRIPTION OF THE DRAWINGS
