Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

As shown in fig. 1-3, an anti-clog hopper assembly according to an embodiment of the present invention includes a bracket 2 and a hopper assembly.

Specifically, the funnel assembly is connected with the support 2 and the material leakage assembly comprises a fixed funnel 11 and a movable funnel 12, the fixed funnel 11 is provided with a material leakage cavity, the material leakage cavity is provided with a top opening and a bottom opening, the movable funnel 12 is positioned at the lower end of the fixed funnel 11 and is connected with the support 2, the movable funnel 12 comprises a plurality of plate sections 121 circumferentially arranged along the bottom opening, the plate sections 121 enclose a material passing cavity opposite to and communicated with the bottom opening, and at least one of the plate sections 121 is movable along the radial direction of the bottom opening relative to the fixed funnel.

It can be understood that the funnel assembly is divided into two funnels connected up and down, the upper fixed funnel 11 is fixed on the bracket 2 for directly receiving the material falling from the belt conveyor, and meanwhile, the material passing cavity of the lower movable funnel 12 and the material leaking cavity of the upper fixed funnel 11 are mutually communicated to form a smooth material flow channel.

It can be understood that the material passing cavity of the movable funnel 12 is formed by enclosing a plurality of plate segments 121 circumferentially arranged along the bottom opening of the fixed funnel 11, so that the plate segments 121 can be separated from each other, and when one or more plate segments 121 of the movable funnel 12 move, the caliber of the flow channel of the movable funnel 12 changes, so that a disturbance effect is formed on easily blocked materials in the funnel assembly.

It should be noted that, the "fixed" of the fixed funnel 11 herein means that the flow passage caliber of the material leakage cavity of the fixed funnel 11 does not change, the "movable" of the movable funnel 12 means that the flow passage caliber of the material passing cavity of the movable funnel 12 can change along with the movement of the movable plate section 121, when the blockage situation occurs in the funnel assembly due to the large-volume material, the dynamic change of the flow passage caliber of the movable funnel 12 can disturb the material or change the circumferential constraint force of the movable funnel 12 on the material, so as to promote the large-volume material to fall off, or when the blockage situation occurs in the funnel assembly due to the large-viscosity material, the flow passage caliber of the movable funnel 12 becomes large, so that the movable space of the blocked material becomes large, and the looseness of the blocked material becomes large, so as to promote the blocked material to fall.

It should be noted that, the minimum flow passage caliber of the movable funnel 12 should be not greater than the bottom mouth flow passage caliber of the fixed funnel 11, so that the 'movement' of the movable funnel 12 can be ensured to play a disturbance role on easily blocked materials in the funnel assembly, and meanwhile, the maximum flow passage caliber of the movable funnel 12 should not be too large, so that the movable funnel 12 is prevented from playing an inapplicable collecting role on the materials flowing through, and the materials are prevented from scattering around.

Preferably, as shown in fig. 1 and 2, the upper end surface of the plate section 121 has a sliding groove 122 extending along the radial direction of the material passing hole, the lower end surface of the fixed funnel 11 is provided with a sliding block 114 arranged along the radial direction of the bottom opening and extending towards the direction away from the bottom opening, and the sliding block 114 is fitted in the sliding groove 122, that is, the top end of the movable plate section 121 of the movable funnel 12 and the bottom end of the fixed funnel 11 are mutually embedded in the form of the sliding groove 122 of the sliding block 114.

It should be noted that, the sliding blocks 114 and the sliding grooves 122 radially arranged along the bottom opening of the fixed funnel 11 form a limiting effect on the movement path of the plate section 121, so as to ensure that the movable plate section 121 of the movable funnel 12 moves according to a predetermined track, and avoid that the movable plate section 121 cannot be reset or can be moved to other positions at will to damage the device.

Optionally, the movable plate section 121 of the movable funnel 12 is matched with the bottom end of the fixed funnel 11 in various forms, for example, the form of a pulley and a sliding rail can be selected, and the form is reasonably selected according to the convenience of mounting and dismounting.

Further, as shown in fig. 1 and 2, a stopper 115 is provided at an end of the slider 114 away from the bottom opening, and the stopper 115 can stop against an outer wall of the plate segment 121 to prevent the plate segment 121 from moving continuously when the plate segment 121 moves to a maximum stroke. Therefore, when the plate segment 121 moves to the position of the limiting block 115, the limiting block 115 generates blocking movement to the continued movement of the plate segment 121, so that the plate segment 121 is prevented from falling off from the sliding block 114, and the reliability and safety of operation are ensured.

It will be appreciated that the maximum travel of the plate segment 121 should be reasonably selected according to the combination of the plate segment 121 and the installable space of the bracket 2, so as to avoid the setting of the limiting block 115 from affecting the maximum flow passage caliber of the movable funnel 12.

Further, as shown in fig. 1 and fig. 2, the anti-blocking funnel further includes a driving member 123, where the driving member 123 is connected to the support 2, and the driving member 123 may drive the plate segment 121 to move, that is, the driving member 123 is fixed on the support 2, and the pushing and pulling movement of the driving member 123 realizes the reciprocating movement of the movable plate segment 121 in the radial direction of the material passing cavity, so that the driving member 123 controls the flow passage caliber of the movable funnel 12 to dynamically change, thereby realizing the disturbance effect on the blocked material in the fixed funnel 11.

Alternatively, the pressure receiving surface of the limiting block 115 may be provided with a pressure sensor, and when the pressure sensor is pressed by the movable plate segment 121 to generate a sensing signal, the pressure sensor may control the driving member 123 to stop.

Alternatively, the driving member 123 may be a driving motor or a hydraulic cylinder, which is selected according to practical application conditions of the production site.

Further, as shown in fig. 1 and 2, there are a plurality of driving members 123, and each driving member 123 can correspondingly drive one plate segment 121 to move.

It can be understood that the plurality of driving members 123 correspondingly drive the plurality of plate segments 121 to move, and when one of the plate segments 121 fails and cannot move, the other plate segments 121 move normally, so as to ensure that the movable funnel 12 plays a disturbing role.

It will be appreciated that the aperture size requirements of the material passing cavity are different when different volumes or viscous materials are conveyed, and the plurality of driving members 12 of the present application can selectively drive the appropriate number of plate segments 121 to move according to actual requirements, so as to meet different size adjustment of the material passing cavity, and effectively and flexibly realize the anti-blocking of the hopper.

Alternatively, as shown in fig. 1 and 2, the plurality of plate segments 121 include a first ring plate and a second ring plate, which may enclose the feed cavity, and the first ring plate and/or the second ring plate are C-shaped plates.

Preferably, the first annular plate and the second annular plate are manufactured by two C-shaped plates, therefore, the notches of the two C-shaped plates are matched relatively to form a material flow channel, the mode is simple to match and easy to manufacture and apply, and meanwhile, the notches of the two C-shaped plates do not influence the centering of material drop, so that the deviation of mineral drop positions caused by movement of the first annular plate or the second annular plate is avoided.

Further, as shown in fig. 1 and 3, the fixed hopper 11 includes a housing 112 and a baffle 111, the housing 112 is connected with the bracket 2, the baffle 111 is provided in the housing 112 and the baffle 111 has a leakage chamber, an outer circumferential surface of the baffle 111 is spaced apart from an inner circumferential surface of the housing 112, and a vibration motor 113 is provided on the outer circumferential surface of the baffle 111.

It is understood that the baffle 111 and the shell 112 form a hollow double-layer structure of the fixed hopper 11, the baffle 111 is arranged on the inner peripheral surface of the shell 112 and forms a material leakage cavity for receiving materials falling from the belt conveyor, meanwhile, a space surrounded by the baffle 111 and the shell 112 is used for installing and arranging the vibration motor 113, and it is understood that the vibration motor 113 arranged on the baffle 111 can cause the vibration of the baffle 111, so that the blocking caused by the adhesion of the materials and the baffle 111 is avoided, the vibration is transmitted to the inside of the materials to cause the vibration of the materials, the disturbance to the materials is formed, the probability of stacking blocking is further reduced, and the discharging efficiency of the anti-blocking hopper component is improved.

Further, the vibration motor 113 is mounted on the outer peripheral surface of the baffle 111, so that the vibration motor 113 is prevented from being damaged by impact of materials, and the flow of the materials in the material leakage cavity is not hindered.

It should be noted that, the baffle 111 protects the casing 112 of the fixed funnel 11, so as to avoid the casing 112 from being worn by materials, prolong the service life of the casing 112, and replace the baffle 111 in time when the baffle 111 is damaged due to wear.

Further, as shown in fig. 1 and 3, the baffle 111 includes a plurality of sub-boards 1111 arranged along the circumferential direction of the housing 112, with gaps between adjacent sub-boards 1111, i.e., the baffle 111 may be surrounded by the plurality of sub-boards 1111.

It will be appreciated that the gaps between the sub-boards 1111 provide active space for the vibrations of each sub-board 1111, avoiding the impediment to relative wear of each sub-board 1111 during vibration, resulting in damage to the sub-board 1111 and the vibration motor 113.

Further, as shown in fig. 1 and 3, the daughter board 1111 is movably connected with the housing 112, that is, the daughter board 1111 is movable relative to the housing 112, so that when the vibration motor 113 is turned on, the daughter board 1111 can smoothly generate a vibration effect to act on the transported material, thereby improving the discharging efficiency.

The belt conveyor conveying system comprises an upper belt conveyor 3, a lower belt conveyor 4 and the anti-blocking hopper assembly, wherein the upper belt conveyor 3 is positioned above the lower belt conveyor 4, the anti-blocking hopper assembly is arranged between the upper belt conveyor 3 and the lower belt conveyor 4, and the upper belt conveyor 3 can rotate to the lower belt conveyor 4 through the anti-blocking hopper assembly.

It can be understood that, because of the space limitation of arranging, the material sometimes needs to be transported to change the transportation direction, at this moment, the anti-blocking hopper component installed between the upper belt conveyor and the lower belt conveyor has the buffering and beam-converging function, namely, the more dispersed material flow of the upper belt conveyor is changed into more concentrated material flow through the anti-blocking hopper component and falls to the lower belt conveyor, and therefore, the arrangement of the anti-blocking hopper component not only avoids the splashing everywhere during material transportation, but also slows down the impact effect caused by material falling to the lower belt conveyor, and prolongs the equipment maintenance period.

According to the belt conveyor conveying system provided by the embodiment of the invention, by adopting the anti-blocking hopper assembly, materials are not easy to be blocked when being conveyed between the upper belt conveyor and the lower belt conveyor, and the material conveying efficiency is high.
