Anti-blocking material forking funnel

Technical Field

The utility model relates to the technical field of bifurcation hopper devices, in particular to an anti-jamming bifurcation hopper.

Background

A bifurcated hopper is a device in which a belt conveyor transports bulk material through different paths for production operations and is typically connected to a head hopper of the belt conveyor. As can be seen in fig. 1, the conventional bifurcated funnel has a housing 1 having an inverted Y-shaped passage and is internally provided with a flap 2, the flap 2 being rotatably mounted by a flap shaft 3 and being externally flipped by a push rod 4 provided on a base 5. The push rod 4 can be in the forms of electricity, liquid, gas and the like, and changes the material flow direction by changing the position of the turning plate 2. Then in operation, the electric push rod 4 pushes the turning plate 2 to be in different positions, so that the flow direction of materials is changed, the reversing discharging effect is realized, and the lower edge of the turning plate 2 is fixed with the turning shaft 3, and the upper edge has large activity amplitude, but the distance between the front inner wall and the rear inner wall of the front and rear edge funnel shell 1 is a fixed value (the front wall and the rear wall of the shell 1 are assembled by straight plates). Then, in the operation of unloading, there is very little cubic material card in the clearance department between turning over board 2 and funnel shell 1 front and back wall, turns over board 2 and blocks easily when promoting to turn over board 2 and change the material flow direction, produces the resistance and causes the moment protection when push rod 4 acts, turns over board 2 unable action, need get into the inside cubic material of cleaing up of branching funnel and just can normal operating, has increaseed maintenance personal's work, influences the normal clear of production operation.

See the prior application for patent publication No.: CN204173559U, patent name: the anti-jamming electrohydraulic three-way distributing valve provides a structure for preventing jamming by arranging a baffle, but the space between the front edge and the rear edge of the overturning plate and the shell cannot be changed because the movable area of the overturning plate in the shell is not changed, so that the problem of jamming in a gap cannot be solved. Therefore, the inventor provides a novel bifurcation funnel which can reduce the occurrence of material clamping and is convenient for maintaining the bifurcation funnel so as to solve the problems.

Detailed Description

The following are only preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model, which is further described with reference to the accompanying drawings and examples.

Example 1:

referring to fig. 2-7, the device comprises a shell 1, a turning plate 2 and a push rod 4.

Wherein, in combination with the attached drawings, the shell 1 is an inverted Y-shaped channel, and can be discharged from left and right outlets at the lower part after being fed from the top. The lower edge of the turning plate 2 is provided with a turning shaft 3, and the turning shaft 3 is rotatably arranged in the shell 1 through two shaft seats. Meanwhile, the turning shaft 3 is connected with the push rod 4 through a connecting rod 15, and in the embodiment, the push rod 4 is an electric cylinder, a cylinder body of the electric cylinder is hinged with the base 5, and the front end of the telescopic rod is hinged with the connecting rod 15. The position of the flap 2 can thus be controlled by the push rod 4 and used for controlling the left and right direction of the material.

In order to prevent the front and rear edges of the push plate from being spaced from the front and rear faces of the housing 1, the front and rear faces of the housing 1 are provided with the projection structures 6 in this embodiment. The protruding structure 6 can prevent the material from being blocked, and the principle is that the material can be automatically removed in the moving process of the turning plate 2.

Specifically, each of the protruding structures 6 includes a fan-shaped through-opening 7 penetrating the front and rear walls of the housing 1, and two pairs of baffle plates 8 respectively covering the fan-shaped through-openings 7. The range of the fan-shaped through opening 7 covers the movement travel range of the turning plate 2, and the baffle 8 is gradually convex in the forward direction or backward direction, which is far away from the shell 1, so that the gap between the front wall and the rear wall of the shell 1 and the front edge and the rear edge of the turning plate 2 in the traditional structure is changed, and the gap distance is increased from small to large.

For clearing the blocked materials, the optimal state needs to enable the materials blocked by the turning plate 2 at two sides to fall along with the pushing of the turning plate 2 by the pushing rod 4 to the stroke middle position so as to achieve the effect of clearing the blocked materials, so that the baffle 8 is positioned at the motion stroke middle position of the turning plate 2 relative to the maximum protruding part of the shell 1.

For convenience of maintenance, in this embodiment the baffle 8 is openably connected to the fan-shaped opening 7. Specifically, the baffle 8 includes two sector plates 9, and the left or right sides of the two sector plates 9 are hinged to the housing 1, respectively, and are adapted to be closed inward to cover the sector openings 7. As can be seen by combining the drawings, the upper edge and the lower edge of the fan-shaped through hole 7 are provided with convex shielding edges 10, and the middle parts of the upper shielding edge and the lower shielding edge 10 are connected through a vertically arranged limiting plate 11. Therefore, after the two sector plates 9 are closed, the sector plates 9 are clamped into the frame formed by the shielding edge 10 and the limiting plates 11, and the left side and the right side of the limiting plates 11 are used for contacting with the inner side edges of the two sector plates 9. This form is also capable of improving the tightness by providing the edge of the limiting plate 11 in contact with the sector plate 9 with a mutually cooperating sealing structure 12. The sealing structure 12 may be provided in the form of a male-female mating overlap structure, as shown in fig. 4 and 7, and may be provided in the form of a labyrinth seal in other embodiments.

At the same time, for the fixation of the sector plate 9. The sector plate 9 and the shell 1 are provided with tension locks 13 which are used for being matched with each other, and the tension locks 13 are used for locking the sector plate 9 after the sector plate 9 is closed. The tension lock catch 13 comprises a lock tongue and a buckle body, wherein the lock tongue is fixed on the shell 1, and the buckle body adopts a deformation form of a connecting rod 15 and can be buckled with the lock tongue in a hanging way.

Finally, reference is made to fig. 2 and 7, in order to prevent the material from blocking the hinge 14, where the sector plate 9 is hinged to the casing 1, is located outside the casing 1. And for convenience of feeding, there is a hopper 16 inserted into the inlet above the housing 1.

In this scheme, to the drawback of traditional bifurcation funnel device structural style, reform transform to the bifurcation funnel promptly changes the well convex formula promptly. The gap between the range of the turning plate 2 and the inner wall of the shell 1 is changed, so that the gap distance is increased from small to large, and the maximum position is fixed in the middle of the turning plate 2. Therefore, the turning plate 2 can run more smoothly in the range of travel, and the baffle 8 structure form convenient to open can also facilitate maintenance personnel to overhaul.

The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
