Detailed Description
In order to facilitate an understanding of the present application, a more complete description of the present application will now be provided with reference to the relevant figures. Examples of the present application are given in the accompanying drawings. This application may, however, be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
In this embodiment, as shown in fig. 1, 2 and 3. The head of the catenary chain of the embedded scraper conveyor comprises a head shell 11, a head wheel cleaning chain divider 12, a head wheel driving group 13 and a chain supporting wheel group 14, wherein the head shell 11 is of a square cylindrical structure, the head wheel driving group 13 comprises a head wheel 133, and the head wheel driving group 13 is rotatably arranged and supported on the left side and the right side of the head shell 11; the head pulley cleaning chain divider 12 is arranged in the head housing 11, the head pulley cleaning chain divider 12 is positioned behind the head pulley driving group 13, and the head pulley cleaning chain divider 12 is aligned in a tooth slot between two tooth walls of the head pulley 133; the sprocket set 14 is rotatably installed and supported on both left and right sides of the head housing 11, and the sprocket set 14 is located at the rear of the head-wheel cleaning chain divider 12. With reference to fig. 3, the left and right sides of the drawing are respectively the front and rear sides, and the up and down sides of the drawing are respectively the right and left sides. The head housing 11 is composed of 5 plates, including a top plate at the upper part, a bottom plate at the lower part, side plates at the left and right sides, and an end plate at the front section, with an opening at the rear end, for butt joint with a shell of the transition section 3 at the rear end, as shown in fig. 1, which is an integral structure of a buried scraper conveyor, the catenary head 1 in the present application is located at the front section and directly butt-jointed with the transition section 3. Through the sealed section of thick bamboo dress structure of design, can prevent the raise dust, avoid external rainwater to get into inside simultaneously, influence the transportation of inside bulk materials.
The head wheel driving set 13 is installed at the position near the front end of the head housing 11, and the driving device 2 drives the head wheel driving set 13, so as to drive the head wheels 133 on the head wheel driving set 13 to rotate together. Thereby driving the movement of the scraper chain engaged with the head pulley 133. The flight chain is not easily separated from the head pulley 133 in the return section when engaged with the head pulley 133 due to the downward gravity of the flight chain. By providing the head wheel cleaning chain divider 12 at the tooth top position of the head wheel 133, the function of smoothly separating the blade chain is achieved. Because the scrapers on the scraper chain directly act on the bulk materials, the bulk materials are formed on the whole scraper chain, and the bulk materials are inevitably adhered and accumulated on the tooth walls and in tooth grooves of the head pulley 133. The head wheel cleaning chain divider 12 is propped against the tooth wall and the tooth groove of the head wheel 133, and can clean materials on the tooth wall and between the tooth grooves of the head wheel 133 under the rotation of the head wheel 133, so that the problem that a scraper chain is blocked and jumps is avoided. The carrier chain wheel set 14 is disposed behind the head-wheel cleaning chain divider 12 for supporting the return flight chain.
In this embodiment, as shown in fig. 2 and 4. The head wheel cleaning chain divider 12 comprises a chain dividing plate 121 and a support plate 122, wherein the chain dividing plate 121 is fixed on the support plate 122 through bolts. The support plate 122 can be fixed in the head housing 11 by welding or bolting, and the split link plate 121 is propped against the head wheel 133 for separating the head wheel 133 and the scraper chain and cleaning the materials on the tooth wall and between tooth grooves of the head wheel 133. The long-term dynamic friction between the chain dividing plate 121 and the head wheel 133 causes the abrasion of the chain dividing plate 121 to shorten, and the chain dividing plate is fixedly connected through bolts, so that the chain dividing plate is convenient to detach and replace. The support plate 122 is provided with a long waist hole through which the bolt passes. The head pulley 133 rotates for a long period of time and rubs against the stationary sub link plate 121, which easily causes abrasion of the sub link plate 121. The holes for connecting the support plates 122 and the split link plates 121 are formed into long waist holes, so that the split link plates 121 can be conveniently adjusted back and forth, installation and debugging are convenient, and meanwhile, the split link plates 121 are prevented from being replaced in a trivial manner. The front section of the split link plate 121 is inclined upward by a certain angle. The split link plate 121 is located at the rear of the head wheel driving set 13, and the front end of the split link plate 121 is tilted upwards by a certain angle, so that the split link plate 121 can be prevented from clamping the head wheel 133. The upper part of the front end of the split link plate 121 is arc-shaped. The upper surface of the end, close to the head pulley 133, of the chain dividing plate 121 is designed into an arc shape, so that the scraper chain can be smoothly separated from the head pulley 133, and the scraper chain is not blocked. And simultaneously releases the catenary space of the return stroke scraper chain between the head pulley 133 and the supporting chain wheel 143, so that the chain can be automatically tensioned without arching.
In this embodiment, as shown in fig. 3. The head wheel driving set 13 further comprises a head shaft 131, a head bearing assembly 132 and a head sealing member 134, the head wheel 133 is fixedly mounted on the head shaft 131, two ends of the head shaft 131 are mounted on the head bearing assembly 132, and the head sealing member 134 is mounted at the extending positions of the two ends of the head shaft 131 and the head shell 11. Head bearing assemblies 132 are mounted on both sides of the head housing 11, and the head shaft 131 is mounted on the head bearing assemblies 132 to freely rotate the head wheel 133. The end of the head shaft 131 is provided with a pulley or a sprocket, and the head shaft 131 is rotated by the driving device 2 above the head housing 11. Dust is easily generated due to the material transported inside the head housing 11. The head sealing members 134 are provided at the protruding positions of the head shaft 131 and the side plates on both sides of the head housing 11, so that dust leakage and environmental pollution can be prevented.
In this embodiment, as shown in fig. 3. The sprocket wheel set 14 comprises a sprocket shaft 141, a sprocket wheel bearing assembly 142, a sprocket wheel 143 and a sprocket shaft sealing member 144, wherein the sprocket wheel bearing assembly 142 is fixedly arranged at two sides of the head shell 11, the sprocket wheel 141 is arranged on the sprocket wheel bearing assembly 142, the sprocket wheel 143 is fixedly arranged on the sprocket shaft 141, and the sprocket shaft sealing member 144 is arranged at the position where the sprocket shaft 141 and the head shell 11 extend. Because the head shell 11 has a certain length, in order to avoid the relaxation caused by the dead weight of the upper layer scraper chain, a supporting chain wheel 143 is arranged at the rear end of the head shell 11, and the supporting chain wheel 143 is driven by the scraper chain to passively rotate. The carrier roller shaft 141 is mounted at both ends on the carrier roller bearing assembly 142 so as to be freely rotatable, thereby driving the carrier roller 143 to rotate. The friction between the scraper chain and the supporting chain wheel 143 can reduce the abrasion and running resistance between the scraper chain and the supporting chain wheel 143. Mounting the axle seals 144 at the extended positions of the axle 141 and the two sides of the head housing 11 can reduce dust leakage in the head housing 11 and avoid affecting the head bearing assembly 132 and polluting the environment.
The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
