Abstract

The utility model relates to a scallop vibration young fry separating machine. The utility model is formed by that: a vibrator is arranged on a motor dual output shaft; double layers of steel mesh screen surfaces and double layers of bottom boards are arranged on an upper frame, and the sloping directions of the two screens and the two bottom boards are opposite; group springs are arranged at four corners between the upper frame and a lower frame; the group springs are composed of compression springs and tension springs. The scallop fries can be divided into three stages by the two layers of screens and the two layers of bottom boards. The machine has the advantages of simple structure, small size, light weight, low power consumption, high productivity and no injury to the scallop fries. Consequently, the utility model is suitable for the seawater aquaculture, and the utility model can particularly meet the needs of the individual producer.

Description

Scallop vibration young seed separating machine

The utility model relates to a kind of scallop vibration young seed separating machine, is used for mariculture and gives the classification of scallop seedling.

People are giving the mariculture industry rich and influential family now, all be to use the crank-linkage type reciprocating grid when scallop seedling carries out classification, this sieve transmission mechanism complexity, volume are big, noise is also big, machine cost height, and the protruding thorn on the easy damaged scallop seedling shell, cause scallop seedling poor growth, also just influenced the output of scallop.

It is simple that the purpose of this utility model provides a kind of transmission mechanism, and the machine volume is little, and cost is low, vibrates adjustable scallop seedling young seed separating machine that does not particularly damage the scallop seedling.

Can realize the purpose of this utility model by following measure:

Setting-up eccentricity oscillator on the double output shaft at motor on the young seed separating machine that constitutes by motor, framework, base, groups of springs; 2 layers of steel wire are installed on the framework are formed inclination screen cloth and 2 layers of base plate.Groups of springs is installed in the Si Jiaochu of upper and lower frames.Off-centred dipole on the motor shaft is that two covers are adjustable; 2 layers of screen cloth all tilt to install, and incline direction is opposite; Groups of springs is made up of compression spring and extension spring.

When the off-centred dipole of the double output shaft axle head of motor vibrates owing to the motor rotation produces, with regard to drive framework and on sieve vibrate, thereby the scallop seedling on the compass screen surface is carried out classification.Scallop seedling less than the superiors' screen cloth eye falls from the upper strata screen cloth, greater than discharge from the upper strata screen cloth.Same, second layer screen cloth also is the same.2 layers of screen cloth can be divided into three grades to scallop seedling peace size.Because spring is positioned on four jiaos of framework, just the vibration of motor oscillator and base is isolated, and makes it to carry out in the operating point reliably work, prevent resonance.

The utlity model has simple in structurely, volume is little, and transmission is simple, and cost is low, and the power of off-centred dipole can steplessly be adjusted, and power consumption only be 1/5 of the reciprocating type sieve of crank connecting link, and efficient but improves 5-10 times.The scallop seedling is not produced damage, in improving output, therefore be particularly suitable for mariculture industry and use effectively.Have the screen cloth of different meshes by replacing, the utility model also can be used to screen cereal crops such as peanut, corn.

Further introduce the utility model below by accompanying drawing:

Fig. 1 is a front view of the present utility model.

Fig. 2 is a vertical view of the present utility model.

Fig. 3 is the A-A cutaway view of Fig. 1.

Fig. 4 is that the B of Fig. 2 is to view.

Fig. 5 is single oscillator figure.

By seeing among Fig. 1,2,4, motor 3 is two shafts, and two oscillators 20,21 are installed respectively thereon.Motor 3 and upper frame 10 are connected by bolt.On the upper frame 10 that is welded into by steel plate and shaped steel upper strata steel-wire screen 6 is installed, it again with on go out mouth 7 and join; The following of upper strata steel-wire screen 6 is upper strata base plate 5, and its opposite with its incline direction again lower floor's steel-wire screen 8 is joined, and is lower floor's base plate 9 below lower floor's steel wire 8, and they go out mouth 2 for 4 times with the middle outlet mouth respectively again and join.Four jiaos between underframe 12 that shaped steel is welded into and footing 1 and the upper frame 10 are equipped with groups of springs 24.Groups of springs 24 has two kinds of springs, and a kind of is extension spring 11, and it is hooked on its two gardens between the upper and lower frames; Another kind is a cluster spring, and it is made up of compression spring 18 and extension spring 17, and compression spring 18 is that the difference seat is on upper spring seat 15 and lower spring cup 19.Extension spring 17 is inclusive in the compression spring 18, and extension spring 17 1 ends are pulled on the lower spring cup 19, and the other end is pulled on the screw rod 16, and is regulated the tightening force of extension spring 17 by screw rod 16 nuts 13 and pad 14.Extension spring 11 and 17 all is the equilibrant force that is used for regulating compression spring 18.

After the scallop seedling that mixes is put on the upper strata steel-wire screen 6, because motor 3 rotations, under the wobbler action of

oscillator

22,21, send vibration, thereby drive upper ledge 10 vibrations, also make the steel-wire screen vibration above it naturally, at this moment the scallop seedling is in the steel-wire screen that tilts glides, less than just dropping on the upper strata base plate 5 of the screen cloth eye of steel-wire screen 6, and greater than the following upper outlet mouth 7 that slides into of screen cloth eye, discharge from upper outlet mouth 7, become one-level scallop seedling.The scallop seedling of falling on the upper strata base plate 5 slides on lower floor's steel-wire screen 8 for 5 times along base plate.Because steel-wire screen 6 upper strata base plates 5 in upper strata are opposite with the incline direction of lower floor's steel-wire screen 8 lower floor's base plates 9, thereby the top that makes the scallop seedling that falls from upper strata base plate 5 fall lower floor's steel-wire screen 8, so just make full use of the compass screen surface of lower floor's steel-wire screen 8, reached the purpose of abundant classification.The upper layer steel wire is the same, greater than flowing down from sieve of lower screen mesh, becomes 2 grades of scallop seedlings in middle outlet mouth 4, and outlet mouth 2 becomes three grades of scallop seedlings under the flowing on lower floor's base plate 9 and drop to.Therefore the scallop seedling is divided into three grades.When motor oscillating, because the damping effect of spring, the power that makes vibration force pass to lower frame 12 and footing 1 significantly reduces, and this is to guaranteeing that just young seed separating machine work reliably is significant.

From Fig. 4, can see, the oscillator the 20, the 21st that motor shaft end is installed is fixed on the motor shaft by

screw

22,23, between two off-centred dipoles 20,21 angle α is arranged, when α is 0 ° just two off-centred dipoles on axle during symmetric arrangement vibration be zero, when α is 180 °, when just two off-centred dipoles overlap, the vibration force maximum, when the α angle when 0 °-180 ° are regulated, just can regulate vibration force, thereby the realization step-less adjustment makes simple in structure practical again.
