Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

A novel shaker basket, as shown in fig. 1, comprising: rectangular screen frame 1, rectangular screen frame 1 include end to end two first horizontal poles 102 and two first stock 101. The ore conveying direction is a direction in which the first long rod 101 at one end is conveyed to the first long rod 101 at the other end.

Nine long second rods 3 are fixedly connected to two first cross rods 102, and here, welding can be adopted, and the second long rods 3 serve to reinforce the stability of the screen frame for the first time.

As shown in fig. 1 and 5, five second cross bars 4 are fixedly connected to two long first rods 101, and the second cross bars 4 play a role in stabilizing the rectangular screen frame 1, so the second cross bars 4 are arranged into pipe pieces with thicker diameters. A plurality of mounting holes 7 are provided along two first long rods 101, the mounting holes 7 serving as mounting stations for the second cross rods 4. The two ends of the second cross rod 4 are provided with inserting rods, the diameter of each inserting rod is smaller than that of the mounting hole 7, and the two ends of the second cross rod 4 need to be inserted into the mounting holes 7 of the first long rods 101 on the two sides and then welded due to the fact that the second cross rod 4 is connected in a welding mode. However, since the second cross bar 4 is configured as a pipe to be stable for processing the screen frame, the second cross bar 4 needs to be configured thicker, and in order to facilitate welding the second cross bar 4 to the first long rods 101 on both sides of the screen frame, it is necessary to configure inserts on both sides of the second cross bar 4, and the diameters of the inserts need to be smaller than the diameter of the mounting hole 7, so as to provide a station that can weld the inserts in the mounting hole 7 at multiple points after the inserts are inserted into the mounting hole 7, that is, a gap between the mounting hole 7 and the inserts is needed, and a gap welded along the mounting hole 7 and the inserts can be provided.

Still include two strengthening ribs 5 of cross connection, the both ends of strengthening rib 5 are passed through connecting plate 6 and are connected respectively in two first stock 101 makes to form triangle-shaped stable structure between strengthening rib 5 and first stock 101, further strengthens the steadiness of bank of screens. The connection position of the connecting plate 6 and the reinforcing rib 5 is provided with a stress release semicircle 601, when the screen frame is subjected to an exciting force, the screen frame has certain deformation, and the deformation force applied to the screen frame can be released through the stress release semicircle 601.

As figure 6, follow be provided with screen cloth 2 in the rectangle bank of screens 1, screen cloth 2 lays on second horizontal pole 4 and second stock 3 on the surface, follows 1 direction of height of rectangle bank of screens sets up if two at least

screen cloth

2, 2 faces of screen cloth are provided with a plurality of sieve mesh, and from top to bottom screen cloth 2, screen cloth 2's sieve mesh diameter diminishes gradually, and great stone is mainly selected out to upper screen cloth 2, and middle level screen cloth 2 mainly sieves out medium stone, can set up the diameter of sieve mesh and then select suitable stone according to the demand. The cross section of the screen 2 is set into a wavy shape, so that the ore can be subjected to exciting forces in multiple directions when the screen 2 vibrates, the collision among the ore is increased, the gap among large-sized ore is larger, small-sized ore is easier to fall on the screen 2, and the screening success rate of each layer of screen 2 is higher. And to the in-process that plane screen cloth 2 received the exciting force, the ore can only receive the exciting force of perpendicular to screen cloth 2 plane, and when the ore that falls into screen cloth 2 is more, and big ore has piled up the lower floor, and when little ore was in the upper strata, the exciting force that relies on perpendicular to screen cloth 2 plane can have little ore to be in big ore top always, makes and can't fall into the below of screen cloth 2. Adopt wavy screen cloth 2, in screen cloth 2 course of operation, the ore can receive a plurality of direction exciting forces, makes the direction of jumping of ore inconsistent, changes the screen cloth 2 that makes small-size ore drop.

In the rectangle bank of screens 1, from each component setting order of direction down: screen cloth 2, second stock 3, second horizontal pole 4, strengthening rib.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
