AI Technical Summary
Traditional hoppers are prone to congestion, serious wear of the hoppers and belts, and spilling of materials during material accumulation and sliding.
A new type of hopper is designed, including the upper, middle and lower hoppers. By installing arc liners and toothed plates on the inside of the hopper, the material moves parabolicly in the hopper, weakens the impact force, and breaks through two throws and collisions to reduce blockage of large pieces of material.
It effectively reduces material accumulation and blockage, extends the service life of the hopper, reduces the wear of the hopper and belt, and reduces the sprinkling of the material.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stacker reclaimers, and specifically relates to a new type of hopper for a stacker reclaimer. Background Technique
[0002] A stacker reclaimer refers to an efficient loading and unloading machine for continuous conveying that can both stack and reclaim materials in a large dry bulk cargo yard. The hopper is an important part of a cantilever bucket wheel stacker reclaimer and is the main structure for the bucket wheel stacker reclaimer to slide, guide, and transfer materials, thereby realizing material stacking and reclaiming. Currently, in the traditional hopper, the operation of materials in the hopper mainly relies on the gravity of the materials themselves, sliding down along the inclined plane of the hopper. The materials are thrown from the unloading roller into the hopper. At the position where the hopper initially contacts the materials, due to the inclined plane contact, it is easy to cause material accumulation and difficult to slide, easily resulting in material congestion. In addition, since the inside of the hopper is an inclined plane, the sliding speed of the materials is relatively fast, causing a large impact force on the lower hopper and the belt at the hopper outlet, easily resulting in serious wear of the lower hopper and the belt, and easily causing material spilling. Content of the Utility Model
[0003] The purpose of the utility model is to provide a new type of hopper for a stacker reclaimer to solve the problems existing in the above background technique.
[0004] The technical solution of the utility model is realized as follows:
[0005] A new type of hopper for a stacker reclaimer includes an upper hopper, a middle hopper, and a lower hopper. The upper hopper, the middle hopper, and the lower hopper are welded in sequence from top to bottom. An inlet is provided on one side of the upper part of the upper hopper, and an outlet is provided at the bottom of the lower hopper. Arc-shaped lining plate A is installed on the surface of the inner sides of the upper hopper and the middle hopper opposite to the inlet. Wear-resistant plate A is bolted to the arc-shaped lining plate A, and toothed plate A is installed on the wear-resistant plate A. Arc-shaped lining plate B is installed on the surface of the inner side of the lower hopper opposite to the arc-shaped lining plate A. Wear-resistant plate B is bolted to the arc-shaped lining plate B, and toothed plate B is installed on the wear-resistant plate B. Lining plate A is installed on the remaining surfaces of the inner sides of the upper hopper and the middle hopper, wear-resistant plate A is bolted to the lining plate A, lining plate B is installed on the remaining surfaces of the inner side of the lower hopper, and wear-resistant plate B is bolted to the lining plate B.
[0006] Further, the upper hopper is welded by steel plates into a quadrangular frustum-shaped structure with a cavity inside.
[0007] Further, the middle hopper is welded by steel plates into an inverted quadrangular frustum-shaped structure with a cavity inside.
[0008] Further, the lower hopper is welded by steel plates into a structure with a straight cylinder shape in the upper part and an inclined cylinder shape in the lower part and a cavity inside.
[0009] Further, a discharging roller is installed at the feeding port.
[0010] Further, an upper support is installed at the connection between the upper hopper and the middle hopper.
[0011] Further, a lower support is installed at the connection between the middle hopper and the lower hopper.
[0012] In the utility model, arc-shaped liners are arranged in the upper hopper and the middle hopper, and an arc-shaped liner is further arranged on the opposite side of the inner side of the lower hopper and the upper arc-shaped liner, so that the material moves in a parabolic shape on both sides in the hopper, weakening the impact force of the material on the lower hopper and the belt; when the material is thrown from the discharging roller into the upper hopper, the contact surface between the material and the upper hopper is arc-shaped, and the material is not easy to accumulate; in addition, tooth plates are arranged in the upper hopper and the middle hopper, and tooth plates are also arranged in the lower hopper. The material is thrown twice and collides with the tooth plates twice for secondary crushing, reducing large pieces of material and not easily blocking the hopper; moreover, bolted wear-resistant plates are arranged in the hopper, which can extend the service life of the hopper, and the replacement is simple and the maintenance is convenient.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.
[0016] Such as Figure 1As shown in the figure, a new type of hopper for a stacker-reclaimer includes an upper hopper 1, a middle hopper 2, and a lower hopper 3. The upper hopper 1, the middle hopper 2, and the lower hopper 3 are welded in sequence from top to bottom. On one side of the upper part of the upper hopper 1, a feed inlet 17 is provided. At the bottom of the lower hopper 3, a discharge outlet 18 is provided. On the inner sides of the upper hopper 1 and the middle hopper 2, on the surfaces opposite to the feed inlet 17, arc-shaped liners A5 are installed. Wear-resistant plates A6 are bolted to the arc-shaped liners A5. Tooth plates A7 are installed on the wear-resistant plates A6. On the inner side of the lower hopper 3, on the surface opposite to the arc-shaped liner A5, an arc-shaped liner B8 is installed. Wear-resistant plates B9 are bolted to the arc-shaped liner B8. Tooth plates B10 are installed on the wear-resistant plates B9. On the remaining inner surfaces of the upper hopper 1 and the middle hopper 2, liners A11 are installed. Wear-resistant plates A12 are bolted to the liners A11. On the remaining inner surfaces of the lower hopper 3, liners B13 are installed. Wear-resistant plates B14 are bolted to the liners B13.
[0017] The upper hopper 1 is welded by steel plates into a frustum of a pyramid structure with a cavity inside.
[0018] The middle hopper 2 is welded by steel plates into an inverted frustum of a pyramid structure with a cavity inside.
[0019] The lower hopper 3 is welded by steel plates into a structure with a straight cylinder type in the upper part and an inclined cylinder type in the lower part and a cavity inside.
[0020] A discharge roller 4 is installed at the feed inlet 17.
[0021] An upper support 15 is installed at the connection between the upper hopper 1 and the middle hopper 2.
[0022] A lower support 16 is installed at the connection between the middle hopper 2 and the lower hopper 3.
[0023] During the operation of the hopper, the material is thrown from the discharge roller 4 at the feed inlet 17 onto the tooth plate A7 of the upper hopper 1. Under the action of the tooth plate A7, large pieces of material are broken. Then the material moves downward in a parabolic shape in the upper hopper 1 and the middle hopper 2 and is thrown onto the tooth plate B10 of the lower hopper 3. Under the action of the tooth plate B10, the large pieces of material are broken for the second time. Then the material continues to move downward in a parabolic shape in the lower hopper 3 until it falls from the discharge outlet 18 onto the belt.
[0024] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
