Abstract

The utility model relates to a self-balance anti-hitch swinging bar grizzly with double grizzly bodies. The utility model adopts two anti-hitch grizzly bodies with different heights, wherein one grizzly body is arranged in front of the other grizzly body; the two anti-hitch grizzly bodies swing relatively by the drive of an eccentric shaft, so the utility model has little vibration during work; during the process of screening refuse, the great turnover of the refuse is added, and the grizzly bodies adopt a structure which can prevent zonal materials and fibriform materials from being wound and hung, so the zonal materials and the fibriform materials can be effectively prevented from being wound and hung on the grizzly bodies, and the screening efficiency of the separation and the selection of the refuse is improved.

Description

Double-sieve self-balance anti-hitch type swinging grizzly

The utility model belongs to the device that carries out sorting by granularity in the urban garbage disposal process.

The rubbish diagrid that adopts in present China urban garbage disposal process, it mostly is the sieve that frame is arranged around adopting, though can carry out by size sorting to rubbish, but to the band shape in the house refuse of composition complexity, fiberous material has no idea to clear up automatically, these band shapes, fiberous material tend to be wrapped on the sieve nest when screening rubbish, hinder the operate as normal and the screening effect of sieve nest.

The purpose of this utility model is that a kind of vibration is little, screening efficiency is high for urban garbage disposal provides, and can prevent band shape, fiberous material lash in the rubbish on sieve nest, and is simple in structure, the sieving garbage device of reliable operation.

Screening plant of the present utility model, be one group with two swing diagrid bodies and make the stairstepping layout, swing on the contrary by eccentric shaft, to significantly reduce the vibration of whole device, and the swing diagrid body that rubbish is put from height falls into low swing diagrid body process of putting, increase once big the stirring of rubbish, to improve screening effect, swing diagrid body is by screen frame, the base plate and the grating that are obliquely installed are made, and one section of grating is fixed on the frame, and its bottom support is on base plate, there is not band shape on the whole swing diagrid body, the place of fibrous material lash, the band shape in the rubbish like this, fiberous material can freely pass through sieve.

The utility model has the advantages that to have adopted height two swings diagrid to be set and to do opposite swing, reduced the vibration of device, in the screening of rubbish, increased stirring greatly of rubbish, improved sieving garbage quality and efficient.The sieve nest that employing constitutes at the bottom of by screen frame, grating and sieve has been eliminated place banded in the rubbish, the fiberous material lash, has guaranteed carrying out smoothly of screening rubbish.

Accompanying drawing has been described embodiment of the present utility model, wherein,

Fig. 1, the utility model operation principle schematic diagram;

Fig. 2, swing diagrid body schematic diagram.

In conjunction with the accompanying drawings the utility model is further described.

Sieve nest 2 is high by one by suspension rod 5 and bearing pin 6 one, and one in front and one in back, frame 1 is hinged, and two diagrid bodies 2 are connected with eccentric shaft 3 by connecting rod 4.

Diagrid body 2 is made of screen frame 7, grating 8, bottom screening plate 9.Fixedly connected with screen frame 7 in the rear end of grating 8, the gripper shoe 10 of grating 8 by fixedlying connected with its bottom surface is fixedly supported on sieve at the end 9.Grating 8 and gripper shoe 10 also can be made in aggregates, and its shape is with the side view of sieve nest, and the sieve end 9 is obliquely installed with the bottom of screen frame 7 fixedlys connected.When sieve was worked, two sieve nests 2 were done swing relatively under eccentric shaft 3 drives.Enter the rubbish of swing diagrid, the swing sorting screenings that is subjected to being located at the swing diagrid body of eminence earlier drops out the diagrid body through the sieve end 9, oversize falls into and continues in the swing diagrid body that is located at lower by the swing sorting, in this process, makes rubbish do once to stand up greatly.Screenings drops out the diagrid body through the sieve end 9, and oversize drops out sieve nest through diagrid body front end.

Claims

1, a kind of pair of anti-hanging rubbish oscillating riddle device of sieve nest self-balancing, comprise frame (1), sieve nest (2), eccentric shaft (3), connecting rod (4), suspension rod (5), hanging axis (6), it is characterized in that two sieve nests (2) one in front and one in back, one high and one low setting is hung on frame (1), and eccentric shaft (3) drives two swing diagrid bodies (2) by connecting rod (4) and does swing relatively.

2, device according to claim 1 is characterized in that swinging the diagrid body by screen frame (7), grating (8), base plate (9), the fixedly connected formation of gripper shoe (10).
