Abstract

The utility model discloses a transmission vibrating mechanism for a flat-rotation screen, and belongs to the field of grain mechanical equipment. The transmission vibrating mechanism solves the problems that a traditional transmission vibrating mechanism is high in accuracy requirement, large in processing difficulty and poor in balance. The transmission vibrating mechanism mainly comprises a box and a main shaft, wherein the protruding end of the main shaft is connected with the upper wall of the box through a first semi-circular fastening ring in a fastened mode, the main shaft is further in bearing connection with a shaft sleeve through a first bearing and a second bearing, the shaft sleeve is fixedly provided with a rotary plate, the top end of the rotary plate is provided with an eccentric weight, the shaft sleeve is further provided with a rotor belt wheel which is connected with a motor through a driving belt, and the lower protruding end of the main shaft is connected with the lower wall of the box through a second semi-circular fastening ring in a fastened mode. According to the transmission vibrating mechanism, the semi-circular fastening rings are adopted as fastening accessories, punching is not needed, the number of the procedures is reduced, safety is high, production cost is reduced, and the production yield is greatly improved. The transmission vibrating mechanism is of a double-bearing structure, balance is high, and service life is greatly prolonged. The transmission vibrating mechanism can be widely applied to the field of flat-rotation screens.

Description

Flat turn sieve transmission vibration mechanism

Technical field

The utility model relates to a kind of cereal cleaning classifying equipoment, specifically, relates in particular to a kind of flat turn sieve transmission vibration mechanism.

Background technology

Flat turn sieve has been widely used and has promoted at Grain Industry, and transmission vibration mechanism is one of important component part of flat turn sieve.United States Patent (USP) NO.4,308,758, the name of innovation and creation is called DRIVE BOX, this patent discloses structure and the operation principle thereof of a kind of transmission vibration mechanism, in continuous practice and use procedure, find gradually that it exists certain not enough, its weak point is embodied in: 1. the fixed form of traditional main shaft adopts in the processing of punching of the upper and lower of main shaft, at punching place construction bolt, main shaft and casing are fixed, this fixed form requirement on machining accuracy is high, difficulty of processing is large, affects production efficiency, and processing cost is high; 2. tradition adopts single bearing frame mode, and single bearing use causes the balance of transmission vibration mechanism poor, after transmission vibration mechanical operation a period of time, can cause equipment fatigue rupture because balance is poor, and service life of equipment is short.

Summary of the invention

The utility model discloses a kind of flat turn sieve and use transmission vibration mechanism, for solving the problem that the requirement of traditional transmission vibration mechanism accuracy is high, difficulty of processing is large and balance is poor.

The utility model is achieved through the following technical solutions:

Flat turn sieve transmission vibration mechanism, comprise casing, main shaft, on main shaft vertical direction through casing, casing is all protruded at described main shaft two ends, be respectively that on main shaft, under protruding end and main shaft protruding end, on main shaft, protruding end adopts semicircle dead ring first and casing upper wall to be fastenedly connected, described main shaft is also by bearing first, bearing second is connected with axle sleeve bearing, axle sleeve is fixed with flap, flap top is provided with weighting block, on described axle sleeve, be also provided with rotor belt pulley, rotor belt pulley is provided with driving belt, rotor belt pulley is by driving belt to be connected with motor, under described main shaft, protruding end is fastenedly connected by semicircle dead ring second and casing lower wall.

Described flap adopts the mode of electric welding to be fixedly connected with axle sleeve.

Described weighting block is adjustable weighting block.

Compared with prior art, the beneficial effects of the utility model are:

1. the utility model adopts semicircle dead ring as fastening accessory, without punching, reduces operation, safe, increases substantially production output when reducing production costs;

2. the utility model adopts duplex bearing to connect main shaft and axle sleeve, and axle sleeve is arranged with identical bearing up and down, solves traditional mechanism balance problem with constructional simple design, and obviously improve service life;

3. the utility model is applied widely, can be widely used in flat turn sieve industry field.
