Technical field

The present invention relates to a kind of shellfish hatchery screening machines.

Background technique

In agricultural production, in order to adapt to the needs of production process, need to educate to required for breeding needed for production Seedling is first screened, to adapt to the requirement in different seedling different sizes, especially in seafood Shellfish culture field, shellfish into Need to meet the partial size income screening of shellfish the needs of different size cultivation in row nursery.Also there is sieve in breeding field at present The service condition of machine is selected to occur, but used structure is generally plansifter mode or trommelling mode, but it is general flat The case where sieve and trommelling mode, which are easy to appear, screens insufficient situation, and sieve pore is easy blocking, and the screen-aperture used It is not adjustable excessively single, can not be adjusted in time when needing aperture to need to adjust, correspond to different grains to adapt to screening machine Diameter screens situation.

Patent CN105830805A discloses a kind of vegetable seedling substrate screening machine, and the screening machine includes roller, rotation Axis, driven wheel, driving wheel, motor, upper support frame；The center of the roller is equipped with rotary shaft；The rotary shaft is mounted on The centre of support frame is provided with rolling bearing between the rotary shaft and support frame；One end of the rotary shaft is fixedly connected with Rolling bearing.Above structure does not make further change to the adjustment in screening aperture, also not preferable to realization screening machine Screening effect proposition have revelatory suggestion.

Summary of the invention

The present invention is directed to the technical deficiency of existing product, and provides a kind of shellfish hatchery screening machine, and the present invention to be solved Certainly the technical issues of, is: improving the screening quality and screening efficiency of screening machine, the sieve that screen-aperture adapts to different size is adjusted Choosing requires, and improves the practicability of screening machine.

The present invention realizes technical purpose by following technological means:

A kind of shellfish hatchery screening machine, including rack are provided with left baffle and the screening across left baffle in the rack Device is connected with feeding device on the left of the right baffle-plate, is connected with discharging device on the right side of the right shell body, the screening plant with Feeding device is connected with discharging device, the screening plant include by bearing seat supports screw-conveyer-shaft, be set in outside screw-conveyer-shaft The adjustable knotter screen bucket in portion.

Each device is arranged in above structure on the rack, in the upper section for making feeding device, screening plant and discharging device Heart line is on same straight line, so that process is smooth when in use for whole device, material to be screened is from feeding device due to weight The effect of power enters screening plant, due to screening plant by bearing seat supports screw-conveyer-shaft, be set in it is adjustable outside screw-conveyer-shaft Knotter screen cylinder is constituted, so the material for entering screening plant is stirred and is transported under the drive of screw-conveyer-shaft, in the mistake of stirring Material friction strainer with screening in journey carries out Effective selection, since the lesser material of limitation partial size of mesh size passes through sieve Aperture fall downwards, the rotation of the used screw-conveyer-shaft of the biggish material of partial size is forwarded to discharging device, the biggish object of partial size Material is screened out from discharge port.

Preferably, vertical height of the left end of the screening plant apart from rack is lower than the right end of screening plant apart from machine The vertical height of frame.

The setting of above structure makes to be transported to the material close to screening plant right end by dragon shaft, since gravity returns It moves back, carries out the screening of one step of row, but the distance transmitted is greater than the distance to retract, the setting of above-mentioned apparatus can extend material and exist Residence time in screening plant can carry out full screening to material to be screened with screening plant.

Preferably, the feeding device is connected with left side baffle, the discharging device is connected with right-hand apron.

Going out above discharging device is partially in preferably, being connected on the adjustable screen drum of the screening plant right end Material mouth.

Preferably, the close bore that can adjust screen drum one end of the discharge port is less than the mouth far from adjustable screen drum one end Diameter, the discharge port side are smooth plane.

The material for being conducive to screen that is provided with of above structure falls to discharging device from adjustable screen drum, then has discharging Device completes the conveying of material, and above-mentioned discharging mouth-shaped is close with rotary table side surface, due to using adjustable screen drum side wall Lateral incision face be circle, therefore the shape setting of discharge port is more advantageous to material and enters discharging device from discharge port.

Preferably, the feeding device includes article putting groove and feed opening, the feed opening setting in article putting groove lower part and It is connected with article putting groove, the one end of the feed opening far from article putting groove is connected with adjustable screen drum.

Preferably, the feed opening includes from the inclined-plane that glove groove bottom is downwardly extending and the song tilted down Face, the inclined-plane are connected with curved surface, are provided with leakage barriers below the junction of the feed opening and adjustable screen drum.

Preferably, being provided with the supporting element connecting with rack below the article putting groove.

Preferably, the adjustable screen drum includes layer 2-4 sieve and the sieve angle demodulator that sieve one end is arranged in.

Object slot is connect preferably, being provided with below the screening plant, described connect offers whereabouts mouth on object slot, described to connect The object groove bottom plane of angulation at 0 ° -5 ° between adjacent two parts, the plane two sides are connected with inclined inclined-plane.

Preferably, the upper side edge on the inclined-plane is connected with vertical plane.

Preferably, being provided with fixed frame on the discharging device on methods, rack, driving electricity is installed on the fixed frame Machine, the driving motor are connect with screening plant.

Preferably, the adjustable screen drum is connected to the motor.

Preferably, the screw-conveyer-shaft is connected to the motor.

The adjustable screen drum of the drive of motor described in above structure and screw-conveyer-shaft rotation, the adjustable screen drum of formation and screw-conveyer-shaft Relative motion can carry out the screening of material.

Preferably, the revolving speed of the adjustable screen drum is less than the revolving speed of screw-conveyer-shaft.

Preferably, the top-down vertical plane of discharge port and the top-down vertical plane of discharging device With intersection, the top-down vertical plane of discharge port is covered by the top-down vertical plane of discharging device Lid.

Compared with prior art the device have the advantages that are as follows:

1, the process entirely screened is to automatically complete, and is used manpower and material resources sparingly, and many places use inclined bevel structure in structure, Convenient for the conveying of material, do not need manually to carry out material conveying.

2, above structure extends the screening time of material, using the relative rotation speed difference of screw-conveyer-shaft and adjustable screen drum to object Material is screened and is transmitted, so that entire screening process is more complete more thorough, improves the efficiency and quality of material screening.

3, using adjustable screen drum, slot size used in material screening can be adjusted, it is different to adapt to Breeding demand.
