Description

Technical Field

[0001] The utility model belongs to the technical field of scraper conveyors, and specifically relates to a feeding section of a scraper conveyor and a feeding mechanism composed of the feeding section. The utility model also relates to a scraper conveyor including the feeding mechanism. Background Art

[0002] The extra-long inlet side flow section of the scraper conveyor is mainly used in feed mills, flour mills, grain processing plants, grain depots and other industries. It is used in the raw grain storage section in the raw grain silo area and the scraper conveyor under the raw grain feeding port.

[0003] A feeding buffer hopper is installed below the ground level of the raw grain feeding port, which is connected to the feed port of the scraper conveyor below the raw grain feeding port. The transported raw grain is placed in the feeding buffer hopper and enters the scraper conveyor through the feed port. The scraper conveyor is then transported to the next equipment (usually a bucket elevator) until it enters the silo.

[0004] There are several ways to feed raw grain into the feeding port: manual feeding, direct unloading by truck, direct unloading by train, etc. In order to improve the efficiency of grain collection, the volume of the feeding buffer hopper is generally designed to be larger. After manual feeding or truck feeding all the raw grain into the feeding buffer hopper in a short time, the raw grain in the feeding buffer hopper can be removed. The raw grain in the feeding buffer hopper is gradually transported by the scraper conveyor.

[0005] Since the feeding buffer hopper is matched with the feeding port of the scraper conveyor, under the above requirements, the feeding buffer hopper will be made very long along the length direction of the scraper conveyor to increase the volume of the feeding buffer hopper.

[0006] The current mainstream solution in the industry: Generally considering the reasons such as plate width and transportation and installation, the middle section of the scraper conveyor is assembled from various standard middle sections. The length of each standard middle section is not more than 3m, and the feed port on the upper cover of the standard middle section is combined with a standard middle section, that is, the length of the feed port is not more than 3m.

[0007] When the volume requirement for the feeding buffer hopper is low, the feeding buffer hopper is generally about 3 meters long or less and can be connected to a standard intermediate section feed port. However, the above structure has the following problems: the feeding buffer hopper is about 3 meters long or less and has a small volume, which limits its practical use.

[0008] When the volume requirement of the feeding buffer hopper is large: the length of the general feeding buffer hopper is much more than 3m, the upper side of the feeding buffer hopper is a complete port, and the lower side of the feeding buffer hopper is divided into several small ports, which are respectively connected with the feeding ports of the same number of standard intermediate sections. The above structure has the following problems: the length of the feeding buffer hopper is much more than 3m, and the scheme of dividing the lower side of the feeding buffer hopper into several small ports reduces the volume of the feeding buffer hopper itself. At the same time, considering the material flowability and preventing material arching, the angle between the side wall of the small port and the vertical line cannot be too large, which further reduces the volume of the feeding buffer hopper. In order to ensure sufficient volume of the feeding buffer hopper, the overall height of the feeding buffer hopper must be increased, which increases the cost of the feeding buffer hopper and the cost of the civil engineering.

[0054] Example 1

[0055] As shown in Figures 1-5 the feeding section of the scraper conveyor 100, comprising a conveyor trough 110, a feeding port 120.

[0056] As shown in Figure 3 the conveyor trough 110 is used to install the upper return chain 610 and the lower conveying chain 620 of the scraper conveyor.

[0057] As shown in Figure 1 in an embodiment, the top of the conveyor trough 110 is provided with a tapered top 111, and the feeding port 120 is provided on the tapered top 111 via a corresponding support rib plate 112. Specifically, the tapered top of the upper return chain is supported on the sidewall of the feeding port by a plurality of welded support rib plates.

[0058] The top plate of the conveyor trough and the tapered top form a closed space in which the upper return chain is located, for preventing material from impacting the upper return chain of the scraper conveyor and preventing material from entering the closed space. The feeding port of the present application directly communicates with the lower conveyor trough, bypassing the upper return chain, which can effectively reduce the load of the chain and reduce the overall energy consumption of the scraper conveyor. The space of the upper return chain is closed relative to the material channel, i.e., not in contact with the material.

[0059] The feeding port 120 is arranged on the conveyor trough 110. The feeding port 120 has a large upper portion and a small lower portion, and is used to guide the material to the lower conveying chain 620 of the scraper conveyor.

[0060] In an embodiment, as shown in Figure 1 the length of the feeding port 120 is the same as the length of the conveyor trough. Specifically, the feeding port 120 comprises two side plates 121 and two end plates 122. The end plates 122 are arranged vertically between the side plates 121.

[0061] In an embodiment, as shown in Figure 3 the side plate 121 comprises a cylindrical portion 1211 and a tapered portion 1212 arranged from top to bottom. The width of the cylindrical portion 1211 is greater than the width of the conveyor trough 110, so that the width (dimension W1 in the figure) of the feeding port of the present application is greater than the width (dimension W2 in the figure) of the conveyor trough, which can realize large-batch feeding. A flange connection portion 1214 is arranged at the upper end of the cylindrical portion 1211, which is used for flange connection of a material feeding buffer hopper. The inner side of the cylindrical portion of the side plate is provided with a support rib plate 112.

[0062] In an embodiment, as shown in Figure 3As shown in the drawings, the taper angle A of the tapered part 1212 of the feeding port is 45-80°. The feeding angle A of the feeding port of the utility model is small, which can ensure smooth flow of the material and prevent arching of the material. The lower end of the tapered part 1212 is provided with an L-shaped connecting part 1213, and the L-shaped connecting part 121 is connected with the bottom flange of the conveyor trough 110.

[0063] In one embodiment, as shown in the drawings, Figure 2 As shown in the drawings, a flow direction sign 123 is arranged on the side plate 122 of the feeding port 120, which can clearly indicate the conveying direction of the material in the conveyor trough.

[0075] (1) When the first rotating rod 1331 and the second rotating rod 1332 are close to each other, the opening sizes of the first flow limiting plate 1311 and the second flow limiting plate 1312 are reduced, the cross-sectional area of the conveyor groove is reduced, and the flow of the scraper conveyor is reduced.

[0076] (2) When the first rotating rod 1331 and the second rotating rod 1332 are far away from each other, the opening sizes of the first flow limiting plate 1311 and the second flow limiting plate 1312 are expanded, the cross-sectional area of the conveyor groove is expanded, and the flow of the scraper conveyor is expanded.
