Description

Technical Field

[0001] The present invention belongs to the technical field of feeders, and particularly relates to a roller feeder. Background Art

[0002] A roller feeder (hereinafter referred to as a roller screen) is a composite device that has both a function of smooth and continuous feeding and a screening function. Upstream is other feeding equipment, generally a plate feeder, and downstream is connected to a crusher. This device consists of multiple groups of rollers, with a relatively large bearing area and screen gap area. When the material is fed into this machine by the plate feeder, the larger materials are transported into the crusher by the special-shaped wear-resistant plates, and the smaller finished materials fall into the discharge chute through the gaps and are transported away by the conveyor belt. In this way, the production capacity of the crushing system is improved, the load on the crusher is reduced, and the service life of the vulnerable parts of the crushing equipment is extended. The overall load of this system is achieved by the variable frequency speed regulation of the plate feeder motor, and the rollers of the roller screen rotate at a relatively high speed for timely transportation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0010] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0011] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0012] Embodiment 1, as Figures 1 to 3 shown, the present application provides a roller feeder, including a base 1, an array of rectangular grooves, a spherical roller bearing 2, a chain case 3, a roller chain 4 and a drive shaft; the spherical roller bearing 2 is installed inside the base 1, one end of the drive shaft is connected to the spherical roller bearing 2, there are a plurality of spherical roller bearings 2, and the plurality of spherical roller bearings 2 are connected by a roller chain 4, and the roller chain 4 is installed in the chain case 3; several arrayed rectangular grooves are provided on the outer side of the spherical roller bearing 2, and the arrayed rectangular grooves are used for crushing materials.

[0013] The self-aligning roller bearing 2 includes an inner bearing ring, an outer bearing ring, and at least one row of roller elements disposed between the inner bearing ring and the outer bearing ring. Additionally, the self-aligning roller bearing 2 includes: a cage for holding and / or guiding the roller elements; and a shield element including an annular shield disposed at a first axial side of the self-aligning roller bearing 2. The annular shield is configured to prevent foreign matter from entering the internal space between the inner and outer rings. The shield element further includes a plurality of male connection elements protruding from the annular shield, and the cage includes a cage side portion disposed at the first axial side, wherein the cage side portion includes a plurality of female connection elements. Each male connection element is inserted into a corresponding one of the plurality of female connection elements and forms a paired connection element, thereby connecting the shield element to the cage side portion.

[0014] Each pair of the paired connection elements may be circumferentially disposed between a corresponding pair of adjacent roller elements in at least one row of roller elements. It has been found that by disposing each pair of the paired connection elements in this way, more available space can be provided for the connection elements of the shield element and the cage side portion. Furthermore, this can allow the connection to be more robust. Further still, each pair of the paired connection elements may be radially disposed above and / or below the pitch circle of the self-aligning roller bearing 2. The pitch circle is well-known to those skilled in the art and may be defined as a circle that intersects the center points of the roller elements of the bearing. By disposing the connection elements above and / or below the pitch circle of the bearing, more space can be used for the connection elements between a corresponding pair of adjacent roller elements. Therefore, the increased available space can allow the connection elements to be configured to have a specific size / shape, making them more robust.

[0015] The self-aligning roller bearing 2 may be provided with an outer radial clearance between the outer radial surface of the annular shield and the outer ring such that a frictionless rotation is provided at the outer radial clearance between the annular shield and the outer ring during use of the self-aligning roller bearing 2. It has been found that an improved sealing function can be provided without increasing the friction during rotation of the bearing, such as in the case of using a sealing lip where increasing the friction during rotation of the bearing may occur. Therefore, a low-friction rotation and a high sealing performance can be provided, and the radial extension of the outer radial clearance is substantially the same around the circumference of the bearing. Still as an option, the self-aligning roller bearing 2 may be provided with an inner radial clearance between the inner radial surface of the annular shield and the inner ring such that a frictionless rotation is provided at the inner radial clearance between the annular shield and the inner ring during use of the self-aligning roller bearing 2. The inner radial clearance has a certain radial width and also extends circumferentially around the bearing.

[0016] The effects of the roller feeder provided in this embodiment: It reduces the stones on the conveyor belt after the roller screen entering the soil screen, reduces the impact on the screen mesh, improves the screening efficiency of the soil screen, and at the same time increases the service life of the screen mesh. More ores can enter the crusher through the roller screen, improving the utilization rate of the crusher and enhancing the overall quality and production efficiency of the intermediate products.

[0017] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
