Technical Field

[0001] The utility model belongs to the field of conveyor belts, and more specifically, relates to an intermediate material dividing device of a belt conveyor. The utility model also relates to a belt conveyor. Background Art

[0002] Belt conveyor is a continuous transport machine that uses a conveyor belt as a traction and load-bearing component. It has the advantages of long transport distance, large transport capacity, small working resistance, easy installation, low power consumption, and less wear. The conveyor belt is wound around the driving roller and various redirecting rollers, and the tension device gives appropriate tension. When working, the conveyor belt is driven by the driving device, through the friction and tension between the roller and the conveyor belt, so that the conveyor belt runs. The material is continuously sent to the conveyor belt and moves with the conveyor belt, thereby realizing the transportation of the material.

[0003] Belt conveyors generally use pear-type dischargers to complete the discharging and unloading of materials. The existing plow-type dischargers have some technical problems that seriously affect production during use: due to the gap between the plow and the belt surface of the belt conveyor, small metal blocks and relatively hard coal blocks or gangue with sharp edges can easily get stuck between the plow and the belt surface, which will scratch or even penetrate the belt; in addition, the part where the conveyor belt edge contacts the plow is most subject to wear by the material, which can easily cause the rubber on the edge of the belt conveyor to age and fall off, and the plow will also form gaps under long-term wear, which has a serious adverse effect on the conveying efficiency of the conveyor belt.

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] Please also read Figures 1 to 3 , the intermediate material dividing device of the belt conveyor provided by the utility model is now described. The intermediate material dividing device of the belt conveyor includes a material dividing component 1 and a redirecting roller group. The material dividing component 1 includes a material dividing channel 11. The bottom of the material dividing channel has two branch channels. The top of the material dividing channel 11 is provided with a first feeding port 111. The bottom ends of the two branch channels are respectively provided with two first material discharging ports 112, and the two first material discharging ports 112 are respectively located on both sides of the width direction of the feeding belt; the redirecting roller group includes a first redirecting roller 21 and a second redirecting roller 22 whose axes are parallel to each other. The first redirecting roller 21 is arranged at the first material discharging port 112, and the second redirecting roller 22 is arranged obliquely below the first redirecting roller 21. The feeding belt is "Z"-shaped and sequentially passes through the first redirecting roller 21 and the second redirecting roller 22. The two first material discharging ports 112 are respectively located on both sides of the feeding belt downstream of the second redirecting roller 22. More specifically, the feeding belt located upstream of the first redirecting roller 21 is the first belt 3 , the feeding belt located downstream of the second redirecting roller 22 is the second belt 4 , and the two first discharge ports 112 are respectively located on both sides of the second belt 4 in the width direction.

[0034] Compared with the prior art, when the material is delivered to the first redirecting roller 21 by the conveyor of the feeding belt, it enters the material distribution channel 11 through the first feeding port 111 under the action of inertia, and then discharges from the two first discharging ports 112 to complete the material distribution operation of the belt conveyor. During the above material distribution process, the material will not be stuck in the gap between the material distribution channel 11 and the feeding belt, so as to ensure the normal operation of the intermediate material distribution device and the belt conveyor in the embodiment, and can solve the technical problem of the existing pear-type discharger being seriously worn due to the material being stuck in the gap between the discharger and the feeding belt during use, thereby improving the reliability and durability of the intermediate material distribution device of the belt conveyor in this embodiment during practical use. In addition to the above beneficial effects, the feeding belt arranged in a "Z" shape in this embodiment provides sufficient redundant space for the installation of the material distribution channel 11, making the overall spatial arrangement of this embodiment more reasonable.

[0035] Based on the above embodiments, a more preferred embodiment is provided. Specifically, a second discharge port 113 that can be opened and closed is provided between the two first discharge ports 112 of the material distribution channel 11, and the second discharge port 113 is provided above the feed belt located downstream of the second redirecting roller 22. More specifically, the second discharge port 113 is located above the second belt 4. In this embodiment, when the second discharge port 113 is opened, the material can fall from the second discharge port 113 to the second belt 4 by free fall after passing through the first feed port 111, so that the material can be continuously transported. When the second discharge port 113 is closed, the material flows out from the two second discharge ports 113 under the diversion effect of the material distribution channel 11, thereby completing the diversion operation of the material. As set above, this embodiment can control the flow direction of the material by opening and closing the second discharge port 113, without the need to control the movement of the discharger body as in the existing pear-type discharger, thereby solving the technical problem that the material is easily stuck between the plow-type discharger and the feeder belt in the process of the existing pear-type discharger moving to the feeder belt.

[0036] In some embodiments, in order to facilitate the control of the flow trajectory of the material, the material distribution channel 11 also includes two material stripping plates 14 symmetrically arranged in the left-right direction within the second material outlet 113. The two material stripping plates 14 are respectively hinged to the second material outlet 113, and the hinge axis is perpendicular to the first redirecting roller 21 and parallel to the horizontal direction. The two material stripping plates 14 have a first state in which the free edges overlap each other to block the second material outlet 113, and also have a second state in which they are away from each other to open the second material outlet 113. In this embodiment, when the two material stripping plates 14 are close to each other, the second material outlet 113 is blocked, and the material falling in the material distribution channel 11 slides to the first material outlet 112 under the guidance of the material stripping plates 14; when the two material stripping plates 14 are away from each other, the second material outlet 113 is opened, and the material can fall from the second material outlet 113 onto the second belt 4, which is convenient for the continuous transportation of the material. Furthermore, the hinge axis of the material stripper plate 14 is located at the intersection of the first material outlet 112 and the second material outlet 113, and a baffle 15 is provided at the upstream end of the branch channel. In the second state, the baffle 15 can overlap the edge of the material stripper plate 14 to block the first material outlet 112, so as to prevent the material from flowing out of the first material outlet 112 due to factors such as jumping when the second material outlet 113 is opened.

[0037] In some feasible implementations, a support bar 16 is further provided in the material distribution channel 11, the center line of the support bar 16 in the length direction coincides with the mirror image plane of the two material diverting plates 14, and the length direction of the support bar 16 is parallel to the rotation axis of the hinge shaft, and in the first state, the two material diverting plates 14 are respectively overlapped on both sides of the support bar 16. The support bar 16 in this embodiment can support the two material diverting plates 14, so that the docking of the two material diverting plates 14 is more stable, and the material diverting plates 14 are prevented from uncontrollable displacement due to the knocking of the material.

[0038] Optionally, based on the above embodiment, in order to facilitate the fluctuation of the material-dividing plate 14, the edge of the material-dividing plate 14 is installed on the hinge shaft, and the plate surface of the material-dividing plate 14 is parallel to the axis of the hinge shaft, and a handle is provided at either end of the hinge shaft, and the handle is used to control the rotation of the hinge shaft. In this embodiment, when the material-dividing plate 14 needs to be fluctuated, the swing angle of the material-dividing plate 14 can be controlled by turning the handle, and the structure of the hinge shaft in this embodiment is simple, easy to operate, and the reliability and durability can also meet the use requirements.

[0039] In some embodiments, the belt conveyor intermediate material distribution device further includes a chute 5, which is disposed below the second belt 4 and with the chute opening facing upwards, and is used to receive the material flowing out of the first discharge port 112. Compared with the prior art, the chute 5 in this embodiment can guide the material falling from the first discharge port 112 to prevent the material from being scattered randomly after flowing out of the first discharge port 112.

[0040] Based on the same inventive concept, the utility model also proposes a belt conveyor, which includes the belt conveyor intermediate material dividing device mentioned above. In addition, the belt conveyor also includes a truss 6, which is used to install the belt conveyor and the belt conveyor intermediate material dividing device, and the material dividing channel 11, the first redirecting roller 21 and the second redirecting roller 22 are all arranged on the truss 6. Compared with the prior art, the belt conveyor in the utility model not only has all the benefits of the above-mentioned belt conveyor intermediate material dividing device, but also, by setting the truss 6, it is convenient to install the material dividing channel 11 and the redirecting roller group mentioned above, and it is conducive to installing the belt conveyor to a suitable height, so that the position arrangement of the belt conveyor in the utility model is more reasonable.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
