Description

Square sieve that sways of high productivity compact

Technical Field

The utility model relates to the technical field of screening equipment, in particular to a high-productivity compact square swinging screen.

Background

The traditional square swinging sieves adopt a mounting mode of lifting or adopting a seat-mounted framework, for example, a novel efficient square swinging sieve disclosed in patent CN2018217849476 adopts a universal coupling to lift the bracket on the bracket. Because the swinging sieve adopting the lifting installation mode has larger occupied space, and the vibration mode is swinging in the horizontal direction or vibrating in the up-down direction, the impact on the screen cloth and the machine base is larger when the sieving machine works.

Aiming at the impact problem of the hoisting installation mode, the prior art has square swinging sieves with supporting installation modes, for example, patent CN2019201529881 discloses square swinging sieves with compact structures, and rubber springs are used as supporting pieces of a sieve box. The traditional swinging sieve lifting mode is replaced by the supporting installation mode, the strip-shaped rubber spring is used as a supporting piece, the sieve box can be rotated in a circumferential mode on the plane where the sieve box is located, the impact on the sieve box and the supporting frame is reduced, and the service life of the device is prolonged.

Square rocking screens have the disadvantage of high accuracy but low throughput, which is also a common problem with conventional rocking screens and cannot meet the high throughput requirements that are typically present in the screening field. In order to meet the capacity requirement, the method can be realized by increasing the number of the operation devices or increasing the size and screening area of the operation devices, wherein the increase of the number of the operation devices requires the purchase of more devices from manufacturers, which obviously increases the operation occupation area and the cost; while increasing the size and screening area of the work equipment requires only a small increase in cost by providing the manufacturer with order requirements, the screening manufacturer user will typically choose to increase the size and screening area of the work equipment.

The applicant finds that the lifting installation mode of the conventional square swinging sieve in the practical process, if the size of the sieve box and the size of the supporting piece are increased blindly, the vibration dynamic balance of the sieve box is easily damaged, and the service life of equipment is influenced, so that a supporting mode capable of meeting the dynamic balance requirement of the large-size sieve box in sieving motion is needed urgently, and the requirement of increasing the sieving operation productivity by adopting low cost is met.
