Description

Technical Field

[0001] The present invention relates to the technical field of hoppers, and in particular to a hopper device and a feeding device. Background Art

[0002] In the coal and chemical industries, hoppers are often used to transport materials. For example, belt conveyors need to use hoppers to unload materials. Another example is that materials piled up in chemical companies need to be moved to other places, and the materials need to be bagged first and then loaded onto trucks for transportation.

[0003] In order to prevent the material from blocking the discharge port, a complex anti-blocking structure is usually configured in the prior art.

[0004] For example, a Chinese invention patent with publication number CN115384951A discloses an anti-clogging funnel assembly, including a bracket and a funnel assembly, the funnel assembly is connected to the bracket and the leakage assembly includes a fixed funnel and a movable funnel, the fixed funnel has a leakage cavity, the leakage cavity has a top opening and a bottom opening, the movable funnel is located at the lower end of the fixed funnel and connected to the bracket, and the movable funnel includes a plurality of plate segments arranged along the circumference of the bottom opening, the plurality of plate segments enclose a material passing cavity opposite to and connected to the bottom opening, and at least one of the plurality of plate segments is movable relative to the fixed hopper along the radial direction of the bottom opening.

[0005] The above patented technology mainly relies on the change of the movable funnel to achieve anti-blocking. In fact, if the material has blocked the discharge port of the fixed funnel, even if the movable funnel is opened, the blockage problem cannot be solved.

[0006] When the material falls from the hopper, if the material falls quickly along one side of the hopper instead of falling evenly and slowly along multiple sides, it is more likely to cause the material to block the discharge port.

[0007] In view of this, it is necessary to provide a novel hopper device and feeding equipment. Summary of the invention

[0008] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a hopper device and a feeding equipment. Under normal circumstances, the diverter cone blocks the feed port of the hopper to prevent foreign matter from falling into the hopper and causing blockage. When in use, the diverter cone rises below the feed port of the hopper and rotates. The annular channel formed between the diverter cone and the wall of the hopper is a feed channel, which can slow down the flow rate of falling materials.

[0014] When the hopper device is in working state, the motor is in stopping state, the diverter cone is in raising state, the diverter cone is below the feed port of the hopper and rotates around the connecting rod.

[0042] like Figure 1-3 As shown, a hopper device provided by one embodiment of the present invention includes a funnel-shaped hopper 1, a diverter cone 2 arranged in the hopper 1, a lifting drive mechanism 3 for driving the diverter cone 2 to rise and fall, and a motor 4 for driving the diverter cone 2 to rotate.

[0043] The diverter cone 2 is wide at the bottom and narrow at the top. There is a cone cavity 23 in the diverter cone 2. The motor 4 is installed in the cone cavity 23.

[0044] The diverter cone 2 is connected to the lifting drive mechanism 3 through a connecting rod 5. The connecting rod 5 extends vertically. The upper end of the connecting rod 5 is connected to the lifting drive mechanism 3. The lower end of the connecting rod 5 extends into the cone cavity 23. The diverter cone 2 and the connecting rod 5 are pivotally connected.

[0045] The motor 4 is fixedly mounted on the lower end of the connecting rod 5 , and the motor 4 is connected to the diverter cone 2 via a transmission mechanism 41 .

[0046] When the hopper device is in the initial state, the diverter cone 2 is in a descending state, and the bottom of the diverter cone 2 is in the discharge port 12 of the hopper 1 .

[0047] When the hopper device is in working state, the motor 4 is in a stopped state, the diverter cone 2 is in a raised state, the diverter cone 2 is below the feed port 11 of the hopper 1 and rotates around the connecting rod 5 .

[0048] The hopper device provided by the present invention comprises a hopper 1, a diverter cone 2, a lifting drive mechanism 3, a motor 4, a connecting rod 5 and the like.

[0049] The hopper 1 is funnel-shaped, wide at the top and narrow at the bottom. The top opening of the hopper 1 is a feed inlet 11, and the bottom opening is a discharge inlet 12. Materials are input from the feed inlet 11 and fall from the discharge inlet 12.

[0050] The diverter cone 2 is in a conical shape, and is inverted in the hopper 1, and is wide at the bottom and narrow at the top. The diverter cone 2 has a cone cavity 23 inside, which is used to install the motor 4 and the lower end of the connecting rod 5.

[0051] The lifting drive mechanism 3 is installed above the hopper 1, and can adopt a cylinder mechanism, a motor screw mechanism, etc. A fixed plate 6 is installed at a preset distance above the hopper 1, and the lifting drive mechanism 3 is installed on the fixed plate 6.

The motor 4 is connected to the diverter cone 2 via a transmission mechanism 41, and is used to drive the diverter cone 2 to rotate relative to the connecting rod 5. The transmission mechanism 41 can be a transmission gear set.

[0054] In normal state, the hopper device is in the initial state, the lifting drive mechanism 3 drives the diverter cone 2 to fall, and the diverter cone 2 blocks the discharge port 12 of the hopper 1 to prevent foreign matter from falling into the discharge port 12 and causing blockage. When in use, the hopper device is in a working state, the diverter cone 2 is driven to rise by the lifting drive mechanism 3, the diverter cone 2 is below the feed port 11 of the hopper 1 and rotates, and the annular channel formed between the diverter cone 2 and the wall of the hopper 1 is the discharge channel, which gradually narrows from top to bottom, which can slow down the flow rate of the falling material. At the same time, the rotating diverter cone 2 also plays a role in distributing the falling material to the surroundings, and the material slides downward along a circle of the wall of the hopper 1, effectively avoiding the blockage of the discharge port 12 caused by the material concentrating on one side of the hopper 1 and falling, thereby improving the performance of the product.
