Description

Technical Field

[0001] The invention relates to the field of transfer equipment for open-pit mines, and in particular to a counter-attack plate assembly with an integral variable cross-section and variable inclination angle suitable for use with viscous materials in high-cold areas and suitable for intelligent dust reduction transfer equipment for open-pit mines. Background Art

[0002] In the actual production of open-pit mines, there will be conditions where multiple materials are transported by a long-distance belt conveyor, and the following problems will exist: in early spring and late autumn, materials are very easy to freeze and stick to the transfer equipment, causing blockage; in the rainy season, the conveyed materials will be blocked due to wetness; the inclination angle of material transportation cannot be controlled during the material transfer process, and the uncontrollable material flow transportation makes the existing transfer points unable to meet people's needs. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the present invention aims to provide a counter-attack plate assembly suitable for intelligent dust reduction and transfer equipment for open-pit mines.

[0004] The technical solution adopted by the invention is: a counterattack plate assembly suitable for intelligent dust reduction and transfer equipment for open-pit mines, and its technical key points are: it includes an upper frame of the counterattack plate, a middle frame of the counterattack plate, a lower frame of the counterattack plate and a short-stroke servo electric cylinder. The upper frame of the counterattack plate is connected to the extension rod of the short-stroke servo electric cylinder by a connecting rod. The short-stroke servo electric cylinder makes forward or backward linear motion, driving the upper frame of the counterattack plate to move horizontally to change the unloading angle between the upper frame of the counterattack plate and the middle frame of the counterattack plate; the lower frame of the counterattack plate is connected to the extension rod of another short-stroke servo electric cylinder. The other short-stroke servo electric cylinder makes forward or backward linear motion, driving the lower frame of the counterattack plate to move horizontally to change the unloading angle between the lower frame of the counterattack plate and the middle frame of the counterattack plate to a specified unloading position.

[0005] In the above scheme, the upper frame of the impact plate is hingedly connected to the middle frame of the impact plate by a concealed hinge support, and the middle frame of the impact plate is hingedly connected to the lower frame of the impact plate by another concealed hinge support. The concealed hinge support is composed of a first connecting plate and a second connecting plate hinged together. The second connecting plate is thicker than the first connecting plate and is used to form a height difference between the components connected to the first connecting plate and the components connected to the second connecting plate, so that the edge of the middle frame of the impact plate overlaps the edge of the upper frame of the impact plate, and the edge of the lower frame of the impact plate overlaps the edge of the middle frame of the impact plate to prevent the concealed hinge support itself from being impacted by materials.

[0006] In the above solution, the first connecting plate and the second connecting plate are hingedly connected via a hinge shaft.

[0007] In the above solution, the second connecting plate has a weight-reducing groove.

[0008] The beneficial effects of the present invention are as follows: the impact plate assembly suitable for intelligent dust reduction and transfer equipment for open-pit mines includes an upper frame, a middle frame and a lower frame of the impact plate, which are connected by concealed hinge supports. The concealed hinge supports not only ensure that the upper, middle and lower sections can withstand high impact, but also ensure that the three sections are overlapped to prevent the hinge supports themselves from being damaged by the impact of materials. In addition, the structure also makes the replacement of the three sections more convenient. The short-range servo electric cylinder is connected to both ends of the upper frame of the impact plate to perform forward and backward linear motion, and the long-range servo electric cylinder is connected to the lower frame of the impact plate, so as to obtain the optimal impact plate shape, which is more conducive to material discharge and avoids material blockage.

DETAILED DESCRIPTION

[0014] To make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the following is a brief description of the present invention in conjunction with the attached Figure 1 to Figure 3 The present invention is further described in detail with reference to the accompanying drawings and specific embodiments.

[0015] The counter-attack plate assembly used in this embodiment for the intelligent dust reduction and transfer equipment for open-pit mines is installed on the chute equipment body. The counter-attack plate assembly is located inside the chute equipment body, and the counter-attack plate assembly 2 is connected to the sliding track of the chute equipment body 1 by means of a sliding bearing seat.

[0016] The counter-attack plate assembly in this embodiment includes an upper frame 1 of the counter-attack plate, a middle frame 6 of the counter-attack plate, a lower frame 8 of the counter-attack plate, a first concealed hinge support 5, a second concealed hinge support 7, a first short-range servo electric cylinder 4, a second short-range servo electric cylinder 11 and a third-range servo electric cylinder 9. The upper frame 1 of the counter-attack plate is hinged to the middle frame 6 of the counter-attack plate by the first concealed hinge support 5, and the middle frame 6 of the counter-attack plate is hinged to the lower frame 8 of the counter-attack plate by the second concealed hinge support 7. The first concealed hinge support 5 enables the middle frame 6 of the counter-attack plate to overlap the edge of the upper frame 1 of the counter-attack plate, and the second concealed hinge support 7 enables the lower frame 8 of the counter-attack plate to overlap the edge of the middle frame 6 of the counter-attack plate. This overlapping structure can effectively prevent the first concealed hinge support 5 itself from being impacted by materials. The first concealed hinge support 5 and the second concealed hinge support 7 used in this embodiment have the same structure, both of which are composed of a first connecting plate 12 and a second connecting plate 14, and a weight reduction groove 15 is also provided on the second connecting plate 14. The first connecting plate 12 is hinged to the second connecting plate 14 by a hinge shaft 13, wherein the second connecting plate 14 is thicker than the first connecting plate 12. For example, the upper frame 1 of the counterattack plate is connected to the first connecting plate 12 of the first concealed hinge support 5, and the middle frame 6 of the counterattack plate is connected to the second connecting plate 14 of the first concealed hinge support 5. Due to the different thicknesses of the two connecting plates, a height difference is formed between the upper frame 1 of the counterattack plate and the middle frame 6 of the counterattack plate, so that the edge of the middle frame 6 of the counterattack plate can overlap the outside of the upper frame 1 of the counterattack plate.

[0017] In this embodiment, the first lug 2 is fixedly connected to the upper frame 1 of the counterattack plate, and the connecting rod 3 is inserted into the first lug 2. One end of the connecting rod 3 is connected to the extension rod of the first short-range servo electric cylinder 9, and the other end of the connecting rod 3 is connected to the second short-range servo electric cylinder 11. The first and second short-range servo electric cylinders make forward or backward linear motions, driving the upper frame 1 of the counterattack plate to move horizontally, and changing the unloading angle between the upper frame 1 of the counterattack plate and the middle frame 6 of the counterattack plate. In this embodiment, the lower frame 8 of the counterattack plate is connected to the extension rod of the third short-range servo electric cylinder 9 by the second lug 10, and the third short-range servo electric cylinder 9 makes forward or backward linear motions, driving the lower frame 8 of the counterattack plate to move horizontally, and changing the unloading angle between the lower frame 8 of the counterattack plate and the middle frame 6 of the counterattack plate to the designated unloading position point. The angle of the counterattack plate is adjustable, and the angle of the counterattack plate can be adjusted by using the best counterattack plate curve fitted by the computer to obtain the optimal operating angle of the counterattack plate.

[0018] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
