Description

Technical Field

[0001] The utility model belongs to the field of bulk material conveying devices, and in particular relates to an adjustable automatic aggregate feed inlet device. Background Art

[0002] There are two commonly used structures for the feed inlet on bulk material conveyor belts: one is a feed inlet with automatic deviation correction function, which has a more complex structure and can automatically adjust incoming materials from different directions to center the material flow, so that the conveyor belt will not deviate due to the non-centering material flow during operation. However, this feed inlet has a complex structure and is too large, and there is often not enough space for arrangement under on-site installation conditions; the other is a feed inlet with adjustable baffles on both sides. When the material flow is stable, the material flow in the feed inlet is adjusted by adjusting the baffles to concentrate the material flow. However, under normal circumstances, the feeding material flow of the conveying equipment is unstable, so it is necessary to frequently adjust the baffles to prevent the conveyor belt from deviating to ensure the normal operation of the equipment, which increases the labor intensity. Utility Model Content

[0003] The utility model provides an adjustable automatic aggregate feed inlet device to solve the technical problems of the existing adjustment structure being relatively complex in structure, large in volume and occupying a large space.

[0004] In order to solve the above problems, the adjustable automatic aggregate feed inlet device provided by the utility model adopts the following technical solutions:

[0005] An adjustable automatic aggregate feed inlet device, comprising:

[0006] A feed hopper, the feed hopper is used to be arranged just above the conveyor belt to flow materials onto the conveyor belt;

[0007] An inclined flow plate, which is fixedly arranged on the inner side wall of one end of the feed hopper, and the bottom of the inclined flow plate extends downwardly and is also located directly below the feed opening of the feed hopper;

[0009] Two baffle plates, the top ends of which are rotatably connected to the inner side walls on both sides of the feed hopper, and the two baffle plates are also located directly above the corresponding side baffle plates; and

[0010] At least two adjusting devices are provided, and at least one adjusting device is respectively arranged on the side walls on both sides of the feed hopper. Each adjusting device includes an adjusting rod. The end of each adjusting rod passes through the corresponding side wall of the feed hopper and is detachably fixedly connected to the feed hopper. The end of the adjusting rod contacts the outer plate surface of the corresponding baffle plate, thereby causing the baffle plate to rotate.

[0011] The above-mentioned adjustable automatic aggregate feed inlet device, wherein each adjusting rod has a threaded portion, and the outer side wall of the feed hopper is provided with threaded holes with the same number as the adjusting rods, so that each adjusting rod is threadedly connected to the feed hopper.

[0016] The above-mentioned adjustable automatic aggregate feed inlet device, wherein each outer side wall of the feed hopper is provided with at least two adjustment devices.

[0017] The beneficial effect is: by rotating the baffle plate around the rotating shaft, the direction of the feed material flow is changed, so that it flows to the side baffle, and the material flow speed is slowed down by the side baffle, and then flows to the conveyor belt through the "funnel area", thereby reducing the direct impact of the material flow on the conveyor belt and preventing the conveyor belt from running off. Since the inclination direction of the on-site chute is fixed, the baffle plate only needs to be adjusted once, avoiding repeated manual adjustments and reducing labor intensity. The overall structure is simple and easy to use, and it can be widely used in the field of bulk material transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0027] Example 1

[0028] refer to Figure 1 , Figure 3 and Figure 4 As shown, an adjustable automatic aggregate feed inlet device in this embodiment includes: a feed hopper 1, an inclined flow plate 3, two side baffles 4, two baffle plates 5 and two adjustment devices 6. The feed hopper 1 is funnel-shaped and is arranged directly above the conveyor belt 2. The material flows onto the conveyor belt 2 by feeding into the feed hopper 1. An inclined flow plate 3 is arranged on the inner side wall of the right end of the feed hopper 1, and the top of the inclined flow plate 3 is welded to the inner side wall of the feed hopper 1, and the bottom is inclined and extends downward. The inclined arrangement of the inclined flow plate 3 can change the direction of the feed flow, and to a certain extent avoid the direct impact of the material flow on the conveyor belt 2. The two side baffles 4 are symmetrically arranged on the inner side walls before and after the feed hopper 1, and the top of each side baffle 4 is welded to the corresponding inner side wall of the feed hopper 1, and the bottom is inclined and extends downward, so that the inclined flow plate 3 and the two side baffles 4 enclose a material discharge area that is inclined downward, narrow at the back and gradually widens at the front.

[0029] Furthermore, the two baffle plates 5 are also symmetrically arranged inside the feed hopper 1, and the front and rear sides of the top of the feed hopper 1 are respectively fixed with rotating shafts 7. The top ends of the two baffle plates 5 are respectively rotatably sleeved on the corresponding rotating shafts 7. An adjusting device 6 is respectively installed on the front and rear side walls of the feed hopper 1. Each adjusting device 6 includes an adjusting rod 61, and each adjusting rod 61 is provided with an external thread. Corresponding threaded holes are provided on the side walls of the feed hopper 1. The adjusting rod 61 is screwed into the corresponding threaded hole, and the end portion abuts against the corresponding side baffle 4. By rotating the two adjusting rods 61, the corresponding side baffle 4 can be driven to rotate, thereby changing the slope of the two side baffles 4.

[0030] When the feed material flow is medium to large, the material flow first gathers in the funnel area below the feed port due to the three-side slopes, and is concentrated into a central material pile. A small part of the material flow leaks down through the funnel area to form a "downward material flow" and flows to the conveyor belt 2. Due to the blocking and deceleration and collection by the inclined flow plate 3 and the side baffle 4, and the small flow rate, the impact of the material flow on the conveyor belt 2 is greatly reduced, and the conveyor belt 2 below is pre-pressed, so that the conveyor belt 2 forms an arc in advance to prevent the material from overflowing to the outside of the conveyor belt 2 when a large amount of material is discharged from the front; except for the material leaking downward from the "funnel area", the central material pile formed in the "funnel area" will form a "forward material flow" and flow to the conveyor belt 2 through the "overflow area" due to the fluidity of the bulk material and the scouring of the upper material flow. Due to the deceleration of the funnel area, the material flow formed in the "overflow area" is also decelerated, which greatly reduces the impact of the material flow on the conveyor belt 2 and extends the service life of the conveyor belt 2.

[0031] When the feed material flow is small, the collection structure formed by the inclined flow plate 3 and the side baffle plate 4 cannot decelerate and centrally collect the small material flow. The material flow will directly impact the conveyor belt 2 through the funnel area, which may cause the conveyor belt 2 to deviate. At this time, the baffle plate 5 can be rotated and offset around the rotating shaft 7 through the adjustment rod 61 to change the direction of the feed material flow so that it flows to the side baffle plate 4. After the side baffle plate 4 is decelerated, the material flow speed slows down and then flows to the conveyor belt 2 through the "funnel area", thereby reducing the direct impact of the material flow on the conveyor belt 2 and preventing the conveyor belt 2 from deviating. Since the inclination direction of the on-site chute is fixed, the baffle plate 5 only needs to be adjusted once, avoiding repeated manual adjustments and reducing labor intensity. The overall structure is simple and easy to use, and can be widely used in the field of bulk material transportation.

[0032] Example 2

[0033] The difference from Example 1 is that in Example 1, an adjustment rod 61 is respectively provided on the front and rear side walls of the feed hopper 1 .

[0034] refer to Figure 2As shown, in this embodiment, two adjusting rods 61 are respectively provided on the front and rear side walls of the feed hopper 1, and each baffle plate 5 is supported by the two adjusting rods 61, thereby enhancing the supporting strength of the overall structure.
