Abstract
The utility model discloses a moment-balanced compound rice-grading sieve, which comprises a rack, a sieving boat and a driving mechanism, wherein the sieving boat is hung on the rack, the driving mechanism comprises a motor and a spindle connected with the motor, the spindle is connected with the center of the bottom frame of the sieving boat, and can rotate along with the motor to drive the sieving boat to rotate along a circular track, an eccentric block is arranged at one side of the spindle, and a reverse eccentric block is arranged at the other side of the spindle. According to the moment-balanced compound rice-grading sieve, the overturning moment of a sieve body can be balanced, and therefore, the durability of wire ropes can be enhanced.
Description
Technical field
The utility model relates to rice screening field, especially, relates to a kind of compound white rice grader of equalising torque.
Background technology
Rice needs to carry out classification by classifying screen according to the difference of grain type after shelling.
A kind of compound revolution white rice grader is disclosed in the patent No. is the patent documentation of 201020270297.0 utility model.As shown in Figure 1, its sieve ship 2 is hung on four angles of frame 1 by four guiding principle silk lifting rope flexibilities; Driving mechanism 3 without acceptance of persons is fixed on the zone line below the sieve ship 2, and driving mechanism 3 is done the revolution of circle track with sieve nest; Sieve ship 2 is made up of four layers of compass screen surface at present.It is fastening that the compressing of every layer of compass screen surface adopts two kinds of end face pressing plate group and side depression bar groups to compress mode.Corner location below relative sieve ship 2 below the frame 1 is equipped with the quadruplet spring bumper.
In the above-mentioned compound revolution white rice grader, material is behind the charging even distributor, enter the sieve layer then, material is made the circle orbiting motion because being subjected to acting on of compass screen surface motion inertia force on the compass screen surface, thereby realize that material and compass screen surface have the condition of work of relative motion, and utilization is cracked rice and the difference of whole grain of rice type, do overlapping revolution at the compass screen surface of plane rotation, friction advance to form automatic classification, material is chosen the rice of four kinds of grades under the compass screen surface configuration of uniqueness and suitable rotating speed: special rice, general rice, crack rice and small brokens.But this compound revolution white rice grader has following defective:
Its sieve nest is hung on four angles of frame 1 by four guiding principle silk lifting rope flexibilities, does the revolution of circle track together by the inertia transmission mechanism without acceptance of persons of sieve nest bottom.The turning torque that produces in motion process is born by the steel wire rope of hanging at four jiaos.When sieve nest weight is more big, the turning torque that produces during motion is just more big, and more high to requirements of Wire Rope, steel wire rope is fragile.
The utility model content
The utility model purpose is to provide a kind of compound white rice grader of equalising torque of the durability that can increase steel wire rope, to solve the flimsy technical problem of steel wire rope.
For achieving the above object; the utility model provides a kind of compound white rice grader of equalising torque; comprise frame, sieve ship and driving mechanism; described sieve ship is hung on described frame; described driving mechanism comprises motor and the main shaft that links to each other with described motor; described main shaft is connected in the center of described sieve hull bottom framework and drives described sieve ship with the motor rotation does round track gyration, and a side of described main shaft is provided with weighting block, and the opposite side of described main shaft is provided with reverse eccentric block.
As further improvement of the utility model:
Described weighting block and described reverse eccentric block are about the axle center symmetric arrangement of described main shaft.
The weight of described weighting block is greater than the weight of described reverse eccentric block.
The utlity model has following beneficial effect:
1, the compound white rice grader of equalising torque of the present utility model, symmetric position at weighting block is provided with the reverse eccentric block that weight is lighter than weighting block slightly, under the prerequisite of the equipment of assurance operate as normal, the turning torque of energy balance sieve nest, and then the durability of increase steel wire rope, prolong the service life of equipment, reduced the time of maintenance of equipment, improved operating efficiency.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.With reference to figure, the utility model is described in further detail below.
Description of drawings

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As 2, shown in Figure 3; the compound white rice grader of equalising torque of the present utility model; comprise frame 1, sieve ship 2 and driving mechanism 3; sieve ship 2 is hung on frame 1; driving mechanism 3 comprises motor 301 and the main shaft 302 that links to each other with motor 301; main shaft 302 is connected in the center of sieve ship 2 bottom frameworks and drives sieve ship 2 with motor 301 rotations does round track gyration, and a side of main shaft 302 is provided with weighting block 303, and the opposite side of main shaft 302 is provided with reverse eccentric block 304.
Symmetric position at weighting block 303 arranges reverse eccentric block 304, can balance the turning torque of sieve nest, and then increase the durability of steel wire rope, prolonged the service life of equipment, reduced the time of maintenance of equipment, improved operating efficiency.
In the present embodiment, as shown in Figure 3, weighting block 303 and the axle center symmetric arrangement of reverse eccentric block 304 about main shaft 302, and the weight of weighting block 303 can make that greater than the weight of reverse eccentric block 304 equipment work is more stable.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
