Abstract
The utility model relates to a granule classification equipment in the grain processing, especially a jib formula rice classifying screen of flatting turn, including being used for driving the drive mechanism that the sieve case is flatted turn, drive mechanism include the electromagnetic braking motor, with the boss rod be connected of sieve case, be equipped with the motor band pulley on the output shaft of electromagnetic braking motor, be equipped with the host computer band pulley on the boss rod, the motor band pulley passes through the drive belt and links to each other with the host computer band pulley. The utility model discloses can automatically removed resonance, need not to establish in addition the damping device, simple structure and greatly increased the use reliability, make things convenient for operations and maintenance.
Description
Technical field
The utility model relates to a kind of grain processing equipment, particularly a kind of derrick type flat-turn rice classifying screen.
Background technology
Because existing hoirzontally rotating white rice grader majority adopts strut mode to support screen box, in use procedure, strut very easily ruptures, and maintenance cost is high.Also have part to adopt suspension rod mode, but easily produce resonance in stopping process, need increase limit vibrating device, mechanism is loaded down with trivial details, cost is high and unreliable.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of derrick type flat-turn rice classifying screen automatically eliminating resonance is provided, change driving body into electromagnetic braking motor by common electric machine, enormously simplify transmission mechanism, and add the dependability of classifying screen.
For realizing above-mentioned technical purpose, the scheme that the utility model provides is: a kind of derrick type flat-turn rice classifying screen, comprise the transmission mechanism for driving screen box flat turn, the boss rod that described transmission mechanism comprises electromagnetic braking motor, is connected with screen box, the output shaft of described electromagnetic braking motor is provided with electrical machine belt pulley, described boss rod is provided with main frame belt wheel, and described electrical machine belt pulley is connected with main frame belt wheel by driving-belt.
And described main frame belt wheel is provided with balancing weight.
The utility model has the advantages that: change driving body into electromagnetic braking motor by common electric machine, enormously simplify transmission mechanism, main frame assembling is relatively simple, operation easy to use and reliability is high.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of transmission mechanism in the utility model.
Wherein, 1, electromagnetic braking motor, 2, electrical machine belt pulley, 3, driving-belt, 4, main frame belt wheel, 5, boss rod, 6, balancing weight, 7, suspension rod, 8, screen box, 9, frame.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, 2, the present embodiment provides a kind of derrick type flat-turn rice classifying screen, comprise the transmission mechanism for driving screen box 8 flat turn, the boss rod 5 that described transmission mechanism comprises electromagnetic braking motor 1, is connected with screen box 8, the output shaft of described electromagnetic braking motor 1 is provided with electrical machine belt pulley 2, described boss rod 5 is provided with main frame belt wheel 4, and described electrical machine belt pulley 2 is connected with main frame belt wheel 4 by driving-belt 3.Described main frame belt wheel 4 is provided with balancing weight 6.
When the utility model uses, when classifying screen needs to quit work, electromagnetic braking motor 1 can be braked instantaneously, and boss rod 5 stops operating, thus makes screen box 8 move quickly through resonance region, avoids screen box 8 and fixture to collide.
The utility model optimizes the structure of hoirzontally rotating white rice grader further, reduces manufacture difficulty and cost, and equipment use is safeguarded convenient.
Claims (2)
1. a derrick type flat-turn rice classifying screen, comprise the transmission mechanism for driving screen box flat turn, it is characterized in that: the boss rod that described transmission mechanism comprises electromagnetic braking motor, is connected with screen box, the output shaft of described electromagnetic braking motor is provided with electrical machine belt pulley, described boss rod is provided with main frame belt wheel, and described electrical machine belt pulley is connected with main frame belt wheel by driving-belt.
