Description

mine funnel

technical field

The present invention relates to a mining funnel.

Background technique

In the process of mineral production, a large number of funnels are required for ore sub-packaging and so on. In the process of use, the ore will frequently rub against the funnel, which will result in a high damage rate of the funnel. Frequent replacement of hoppers brings higher production costs.

In addition, when the ore falls, the impact force is large, and it will bounce off, so a lot of ore is ejected from the funnel, which increases labor intensity and has poor buffering capacity.

The present invention is achieved through the following technical solutions: a mining funnel, comprising an outer ring, and an inner ring installed in the middle of the outer ring, the inner ring has the same structure as the outer ring, and the middle of the inner ring has the same structure as the outer ring. There is a material guide cavity, and the inner wall of the material guide cavity is provided with more than one buffer rod parallel to the horizontal plane around the material guide cavity. One end of the buffer rod is provided with a rotating shaft on both sides, and the buffer rod is rotated and installed on the device through the rotating shaft. In the fixed seat on the inner ring, an installation groove is arranged in the middle of the fixed seat, one end of the buffer rod is arranged in the installation groove, and its rotating shaft is rotatably installed in the rotating shaft holes on both sides of the inner wall of the installation groove, and each rotating shaft is The suit is equipped with a torsion spring, and the buffer rod is parallel to the horizontal plane through the torsion spring in its natural state.

Preferably, a material leakage hole is provided in the middle of the outer ring and the inner ring.

Preferably, the inner wall of the outer ring is provided with more than one latching position around the outer ring, the outer wall of the inner ring facing each latching position is provided with a corresponding latching, and the inner ring is clamped in the latching position through the latching middle.

Preferably, more than one hollow layer is disposed in the middle of the outer ring, the outer ring and the inner ring are made of plastic, and the more than one buffer rods are made of wear-resistant metal material.

Preferably, the outer end of the fixing seat is mounted on a fixing ring, and the fixing ring is detachably embedded in the annular groove opened on the inner wall of the inner ring.

The beneficial effects of the present invention are as follows: the funnel of the present invention, through the buffer rod, can ensure the buffering when the material is dropped, reduce the impact with the funnel, ensure that the material does not bounce, and guide the ore to fall through the buffer rod, and the ore slides down with the buffer rod surface. Contact, increase the service life of the inner ring, the design is very novel, in addition, the inner and outer rings can be easily disassembled, saving costs.

FIG. 1 is a schematic diagram of the overall structure of the present invention.

The codes in the figure are: 1 is the leakage hole, 2 is the hollow layer, 3 is the outer ring, 4 is the buckle, 5 is the inner ring, 6 is the buffer rod, 7 is the fixed seat, and 8 is the rotating shaft.

Detailed ways

As shown in Figure 1, the mining funnel includes an outer ring 3, and an inner ring 5 installed in the middle of the outer ring 3. The inner ring 5 has the same structure as the outer ring, and there is a material guide cavity in the middle of the inner ring 5 The inner wall of the guide cavity is provided with more than one buffer rod 6 parallel to the horizontal plane around the guide cavity. One end of the buffer rod 6 is provided with a rotating shaft 8 on both sides, and the buffer rod 6 is rotated and installed on the inner ring through the rotating shaft 8 In the fixed seat 7, an installation groove is arranged in the middle of the fixed seat 7, one end of the buffer rod is set in the installation groove, and its rotating shaft is rotatably installed in the rotating shaft holes on both sides of the inner wall of the installation groove, and each rotating shaft is sleeved with a The root torsion spring (not shown) is parallel to the horizontal plane through the torsion spring in the natural state of the buffer rod 6 .

In this embodiment, a material leakage hole 1 is provided in the middle of the outer ring and the inner ring. The inner wall of the outer ring surrounds the outer ring with more than one clamping position, and the outer wall of the inner ring facing each clamping position is provided with a corresponding buckle 4 , and the inner ring 5 is clamped in the clamping position through the buckle 4 . When the inner ring is damaged after long-term use, we can remove the inner ring and replace it with a new one to save costs, and the structure of the outer ring can be made of more beautiful materials.

In this embodiment, more than one hollow layer 2 is disposed in the middle of the outer ring, the outer ring and the inner ring are made of plastic, and more than one buffer rod 6 is made of wear-resistant metal material. Since there is a hollow layer in the middle of the outer ring, when the ore is impacted, it can absorb a lot of vibration force, and the sound is also smaller, which can also improve the overall service life and make it softer to use.

In this embodiment, the outer end of the fixing seat is mounted on a fixing ring (the embedded structure is not shown), and the fixing ring is detachably embedded in the annular groove opened on the inner wall of the inner ring. Since the frequency of replacement of the inner ring is higher than that of the outer ring, after the inner ring is used, take out the fixing ring, and install the fixing ring and the buffer rod installed on the fixing ring on the new inner ring.

In the natural state, each buffer rod is parallel to the horizontal plane. When the ore enters the funnel, it will contact the buffer rod, and each buffer rod is pressed down by gravity, so that the speed of the ore falling into the funnel will be reduced, reducing the impact on the inner ring. The impact and wear of some larger ore press down the buffer rod, and slide down the buffer rod to the leakage hole, which is very practical.

The beneficial effects of the present invention are as follows: the funnel of the present invention, through the buffer rod, can ensure the buffering when the material is dropped, reduce the impact with the funnel, ensure that the material does not bounce, and guide the ore to fall through the buffer rod, and the ore slides down with the buffer rod surface. Contact, increase the service life of the inner ring, the design is very novel, in addition, the inner and outer rings can be easily disassembled, saving costs.
