Abstract
The utility model belongs to the fishing tools, particularly a fishing device for seabed shellfish. The utility model is provided with a limiting device which can randomly adjust soil-excavating depth and palladium teeth are changed into a streamline form, and therefore, excavated soil is easy to slide into a screen along a streamline surface. The utility model is also provided with a soil-ploughing device to play the action of loosening the soil so that the fishing device can realize continuous soil excavation and has the advantage of high work efficiency.
Description
The utility model relates to the instrument of fishing for, specifically a kind of seabed shellfish catching device.
As everyone knows, existing seabed shellfish catching device is formed skeleton by skeleton, palladium tooth, screen cloth and is formed with round steel weldering system, the lower end of skeleton evenly is welded with some palladium teeth, the palladium tooth is a straight-tooth, makes with round steel, and an end is taper, the other end welds mutually with skeleton, screen cloth is the pocket-shape screen cloth that the polyethylene from high pressure process fishing net is made, and the sack of screen cloth is connected in palladium tooth, skeleton rear end, and the shellfish catching device links by cable wire and fishing boat.When fishing boat drags the shellfish catching device by cable wire, before the palladium teeth directional, downwards insert and go, when being inserted into certain depth (submarine soil layer contacts with skeleton), the palladium cingulum earth and is drawn out soil layer, the soil that digs out is delivered in the screen cloth and is washed, after treating that the regolith sieves, the palladium tooth is inserted again forward, downwards and is gone, and is repeating said process.This seabed shellfish fishing device has uncontrollable digging depth, operation not to have continuity, ineffective shortcoming.
The purpose of this utility model just is to overcome the deficiencies in the prior art, and a kind of positioner that has is provided, and can arbitrarily determine or adjust digging depth, can continuous unbroken operation, the seabed shellfish catching device of high efficiency.
For the feature of the present utility model that achieves the above object be an end of left limit bar and right limit bar be respectively equipped with the native device of plough and with the welding mutually of skeleton upper end, the other end is respectively equipped with position limiting slide block, is streamlined palladium tooth with the palladium tooth that weld mutually the skeleton lower end.The utility model is owing to be provided with the stopping means that can arbitrarily adjust digging depth, and the palladium tooth changes streamlined into, makes that the soil that has dug is very easy to slide in the screen cloth along the palladium tooth, is provided with the native device of plough, plays loosening function, makes catching device realize shoveling continuously, has improved operating efficiency.
Description of drawings:
Accompanying drawing is a kind of structural representation of the present utility model, also is the schematic diagram of a kind of embodiment.
Mark among the figure: skeleton 1, palladium tooth 2, the native device 3 of plough, left limit bar 4, right limit bar 5, position limiting slide block 6, screen cloth 7, cable wire 8.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further: as shown in the figure, skeleton 1 usefulness round steel weldering system forms, palladium tooth 2 usefulness round steel are processed into streamlined, weld mutually with skeleton 1 lower end equably, left limit bar 4 and right limit bar adopt angle steel to make, left limit bar 4 and right limit bar 5 and an end are respectively equipped with the native device 3 of plough, and weld mutually with skeleton 1 upper end, the other end is respectively equipped with position limiting slide block 5, screen cloth 7 is pocket-shape screen clothes that the polyethylene from high pressure process fishing net is made, its sack is connected in the upper and lower side of skeleton 1, and the shellfish catching device links by cable wire 8 and the fishing boat fishing boat that links.During work, adjust the height of position limiting slide block 6 earlier, determine digging depth, again catching device is put into marine, fishing boat drags seabed shellfish catching device by cable wire 8 and advances, palladium tooth 2 and plough native device 3 under the tension of own wt and cable wire 8, in the downward-sloping insertion soil, when arriving certain depth, under the effect of position limiting slide block 6, make palladium tooth 2, the front end of ploughing native device 3 is tending towards parallel, seabed shellfish catching device keeps certain depth to move ahead under the drive of fishing boat, and by palladium tooth 2 and plough soil that native device 3 dug and slide in the pocket-shape screen cloth 7 that is connected in skeleton 1 rear end along the streamiline surface of palladium tooth 2, the soil in the screen cloth 7 is under the flushing of the current of relative motion, very fast being sifted out, the shellfish that is mixed in the soil is selected and stays in the net.
Claims (1)
1, a kind of seabed shellfish catching device, be provided with skeleton, screen cloth, it is characterized in that an end of left limit bar and right limit bar is respectively equipped with the native device of plough, and weld mutually with the both sides, upper end of skeleton, the other end is respectively equipped with position limiting slide block, is streamlined palladium tooth with the palladium tooth that weld mutually the skeleton lower end.
