Description

Suspended screen

Technical field

The utility model relates to sieving machine technical field, especially a kind of suspended screen.

Background technology

Wood chip is except can preparing active carbon, phenolic moulding powder, outside sawdust-board, also alcohol can be produced, fodder yeast or the culture medium etc. as mushroom, timber must carry out sieving and grading through the wood chip of chipper or wood chipping equipment processing output, present chipper is all to high efficiency future development, processing usefulness is multiplied, and vibratory sieve supporting with it does not develop, the screening effeciency of existing vibratory sieve cannot toweringly with up-to-date chipper be joined, existing suspended vibration sieve respectively installs a motor in the both sides of sieve nest, motor via reducer structure drives power transmission shaft, and then band movable eccentric wheel rotates, this suspended vibration sieve transmission efficiency is high, screening frequency and amplitude can regulate, but shortcoming is sieve nest both sides respectively installs a motor and a reducing gear, cost is high, and the eccentric wheel of sieve nest both sides is not easy to regulate synchronously.

Utility model content

The technical problems to be solved in the utility model is: not easily regulate synchronous problem to solve high, the eccentric wheel of existing suspended vibration sieve cost, provides a kind of and saves the synchronous suspended screen of cost, eccentric wheel.

The utility model solves the technical scheme that its technical problem adopts: a kind of suspended screen, comprise sieve nest, suspension holdfast, motor and vibrating device, described sieve nest is suspended on described suspension holdfast by swinging hanger bar, described vibrating device is arranged on sieve nest both sides, described motor output shaft connects vibrating device, described vibrating device comprises eccentric wheel and rotating shaft, described eccentric wheel is fixedly mounted on the two ends of rotating shaft, described rotating shaft top is provided with belt pulley, the output of described motor is connected with two Timing Belts, the belt pulley V belt translation of every root Timing Belt and corresponding side, described 2 Timing Belts are connected with the belt pulley of sieve nest both sides respectively, described motor output shaft, Timing Belt and belt pulley composition V belt translation reducing gear, motor drives belt pulley by Timing Belt, thus eccentric wheel is rotated, two Timing Belts are all connected with motor output shaft, therefore the eccentric wheel at sieve nest two ends can synchronous axial system.

Further, the top of described vibrating device is provided with horizontal gird, and the two ends of described horizontal gird are fixed on suspension holdfast, and described motor is fixed on described horizontal gird.

Further, the quantity of described swing hanger bar is 4, and upper end and the suspension holdfast of described swing hanger bar are hinged, lower end and sieve nest sieve nest four angles place hinged, sieve nest is hung, is convenient to sieve nest and does and similarly revolve sieve motion, thus reach the object of screening.

Further, the angle of described sieve nest and horizontal plane is 8 °.

Further, described sieve nest is provided with at least one deck screen cloth, and its mesh aperture is for reduce successively from top to bottom for every layer of screen cloth, and the orlop of described sieve nest is provided with stock guide, and the wood chip of different screen cloth screening can do different purposes.

Further, every layer of screen cloth of described sieve nest and stock guide are all provided with discharging opening.

The beneficial effects of the utility model are, motor output shaft connects 2 Timing Belts, 2 Timing Belts are connected with the belt pulley of sieve nest both sides respectively, motor output shaft, Timing Belt and belt pulley form 2 V belt translation reducing gears, do not need to use reducing gear in addition, reduce cost, motor drives belt pulley by Timing Belt, thus eccentric wheel is rotated, two Timing Belts are all connected with motor output shaft, and therefore the eccentric wheel at sieve nest two ends can synchronous axial system.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is A place enlarged drawing in Fig. 1.

In figure: 1. suspension holdfast, 2. swing hanger bar, 3. sieve nest, 31. screen clothes, 32. stock guides, 33. discharging openings, 4. motor, 5. eccentric wheel, 6. belt pulley, 7. Timing Belt, 8. rotating shaft.

Detailed description of the invention
