Abstract
The utility model relates to a vibration sieve with joint sieve plate, which comprises a set of sieve boxes and a plurality of joints of sieve core combinations. The bracket of each joint of the sieve core is provided with a vibration-stimulating source. A primary vibration absorbing spring is arranged between a sieve plate and the sieve box. The sieve plates are connected in staircase mode. The bottom of the sieve box is supported with a secondary vibration damping supporting base composed of a secondary vibration absorbing spring fixed between an upper rigid support board and a lower rigid support board. The utility model is characterized in that both sides of the upper side of each joint of the sieve plate is respectively provided with the sieve plate capped edges higher than the sieve surface on each sieve plate along the direction of motion. In the improved sieve with joint sieve plate, material doesn't directly rub the sieve box in the sieving course. The utility model has the advantages of convenient change of sieve plates, primary material economization and effective elongation of the service life of the utility model.
Description
The utility model relates to a kind of segmental appendage vibratory sieve, is widely used in the usefulness of the material screening in coal, mine.
Existing 2190225711.0 a kind of " segmental appendage sieve ", form by screen box, sieve nest, isolation spring, it is characterized in that: have the merogenesis sieve plate to use bolted on the sieve plate carriage on the vibrating motor, between segmentation sieve plate and the screen box once isolation spring separate, each segmentation sieve plate is staged and connects, and the sieve nest sealing is contained in the screen box.This segmental appendage sieve has sieve nest to be separated with screen box, the sieve plate sectional vibration, self seals dust suction, and volume is little, in light weight, advantages such as energy savings do not have rib but weak point is the sieve plate upper surface, do rib by the screen box wall during work and stop material to two lateral movements, screen box wall easy to wear, cause complete machine to scrap, also cause screen box tall and big simultaneously, waste material.
The purpose of this utility model is a kind of improved segmental appendage sieve of design, the material screen box that can directly not rub in screening process, and it is convenient to change sieve plate, saves material, and effectively prolongs the service life of complete machine.
Task of the present utility model is finished as follows, it includes one group of screen box, the combination of more piece sieve core, be fixed with exciting source respectively on each knotter screen core carriage, be separated with isolation spring between sieve plate and the screen box one time, be ladder between each knotter screen plate and connect, the screen box bottom support has by last, the secondary vibration damping holder that the two-stage vibration isolation spring installed between the following rigid support plate is formed is characterized in that: each is fixed with the sieve plate rib that is higher than compass screen surface respectively along direction of motion both sides above the knotter screen plate.
The utlity model has following advantage: sieve nest is installed in the screen box, the sieve nest sectional vibration, and self seals dust suction, the material screen box that can directly not rub in screening process, it is convenient to change sieve plate, and screen box reduced than originally and alleviated, save material, can effectively prolong the service life of complete machine.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Among the figure, 1. sieve plate 2. sieves rigid support plate 8 on 5. shock-absorbing springs of core carriage 3. exciting sources, 4. sieve plate ribs, 6. screen boxs 7., following rigid support plate 9. two-stage vibration isolation springs.
Describe embodiment in detail in conjunction with above accompanying drawing, a kind of segmental appendage vibratory sieve of the utility model can be vibrator or vibrating motor by being fixed with exciting source 3. exciting sources on sieve plate 1, the sieve core carriage 2.Separate by isolation spring 5 of two rows between sieve plate 1 and the screen box 6, play damping effect.Being ladder between each knotter screen plate head and the tail connects, each is fixed with the sieve plate rib 4 that is higher than compass screen surface respectively along the material movement direction in both sides above the knotter screen plate 1, and screen box 6 bottom supports are by the secondary vibration damping holder of being made up of last rigid support plate 7, following rigid support plate 8 and two-stage vibration isolation spring 9.During this machine work, material falls on the compass screen surface of first joint vibratory sieve from charging aperture, material is sized on one side along movement locus in first knotter screen face upper sieve plate rib 2, advance on one side, fall and do further screening on two layers of compass screen surface less than the saturating sieve of the material of sieve aperture, do not have the material of sieve to move on and be admitted to the screening of proceeding next stage on next knotter screen face, so mode goes on, and reaches the purpose of screening step by step.There is not the material of sieve to flow out at last from slag notch.Whole screen box with divide the knotter screen core to adapt to make stairstepping, the screen box wall does not contact mutually with oscillating plate, the material screen box that can not wear and tear is convenient to replacing after the sieve plate wearing and tearing.
