Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 is cage body, 2 is netting gear, and 3 is food cage, and 4 is bail group, and 5 is draw-gear, and 6 is stay cord, and 7 is weighted spherical ball.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
As shown in Figure 1, a kind of Crabbing device pullled break-in and not easily block, comprise cage body, food cage, bail group, draw-gear and stay cord, described cage body 1 is made up of up big and down small two beckets and netting gear, upper becket is round metal endless tube, and described netting gear is connected between upper and lower becket; At netting gear internal upper part, upper becket is arranged the funnel-form mesh sheet that the centre of an arc is porose again, just not easily escape after crab digs into.
Described cage body bottom is provided with the food cage of metal.
Described bail group has three groups, and often organize two bails, be welded on upper and lower becket respectively, three groups of bail groups are respectively by upper and lower becket trisection; Described draw-gear is pull rope, has a, b, c tri-pull ropes; Bind is fixed on a bail of lower annulus in one end of each pull rope, and the other end of pull rope passes in the bail of corresponding upper annulus, and extends out; By pullling adjustment to three pull ropes respectively, the lead of tricing line, for adjusting Crabbing device center of gravity.
Be provided with three weighted spherical ball in described round metal endless tube, each weighted spherical ball is free to slide within the scope of 120 degree; Draw-gear is made up of a, b, c tri-pull ropes.By pullling adjustment to three pull ropes respectively, the lead of tricing line, for adjusting Crabbing device center of gravity.
Described cage body top is connected by stay cord, for mentioning Crabbing device.
Three pull ropes of described draw-gear can independently be pullled, and different wire saws directions is different.
The utility model can operate when using according to the following steps:
(1) food is placed in food cage, catches 2 of cage body beckets to be thrown in water simultaneously, after stay cord and pull rope being fixed, place a period of time, luring crabs class.
(2), when needing to reclaim trap for catching crabs, only need pull stay cord and trap for catching crabs is left the water retract, collect the crab of trapping.
(3) hindered by one block of projection rock if retract cage body in process, pull stay cord when trap for catching crabs can not be pulled out, unclamp stay cord, pull rope a is pullled to b, c section center, make cage body overturn departs from rock obstruction.
In addition:
(1) if cage body is hindered by adjacent two blocks of rocks, pull stay cord when trap for catching crabs can not be pulled out, unclamp stay cord, pull rope a is pullled to its direction, place; If cage body can't be pulled out, then pull rope b is drawn to the direction of b; Can again attempt pullling different pull ropes, till trap for catching crabs can being mentioned.
(2) if cage body is hindered by the precipitous cliff of displacement, unclamp stay cord, by pull rope a to pull-up, if draw motionless, unclamp a, pull b, c simultaneously, cage body is mentioned.
(3) if cage body is stuck in gully, then pull a, b, c clockwise successively, or pull c, b, a counterclockwise successively.
(4) by pullling the adjustment orientation of trap for catching crabs in water above, and relative low side natural subsidence in water of trap for catching crabs becket is made by the gravity of mobilizable weighted spherical ball, thus more easily depart from barrier, be convenient to whole trap for catching crabs adjustment direction, avoiding obstacles reclaims smoothly.
Cage body is designed with three pull ropes, for drawing the direction of cage body.When cage body is blocked by the stone at the bottom or foreign material by drawing different pull ropes to change the direction of cage body, thus spinning off, can avoid losing trap for catching crabs, causing economic loss, affect environment.
