SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an improve crucian carp, carp fry hatching pond of embryonated egg survival rate.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

The utility model provides a crucian carp, carp fry hatching pond, includes the cell body, the cell body sets up to the rectangle, the internal edge of cell body is equipped with the telescopic link respectively, and the telescopic link is connected with the cell body diapire is perpendicular, and two liang of a set of and every group of telescopic link are equipped with the locating lever respectively on, and the both sides of locating lever level and locating lever link to each other with the one end that the cell body was kept away from to the telescopic link respectively, are equipped with a plurality of connecting pieces and a plurality of net piece on the locating lever, and the connecting piece links to each other and.

By adopting the technical scheme, after the pool body is filled with water, before fertilized eggs are put into the pool body, a worker firstly and uniformly coats adhesive fertilized eggs of crucian and common carp on each net piece, the fertilized eggs are not bonded into a group any more, then the telescopic rod is enabled to extend out of the pool body, one end of the telescopic rod far away from the pool body is connected with the positioning rod, so that the positioning rod moves along the direction far away from the pool body along with the telescopic rod, then the worker sequentially connects each net piece with the connecting piece on the positioning rod in a one-to-one correspondence manner, after all the net pieces are positioned on the positioning rod, the worker presses the positioning rod downwards to enable the telescopic rod to be shortened, so that the positioning rod returns into the pool body along with the telescopic rod, all the net pieces also enter the pool body together, the fertilized eggs coated on the net pieces are positioned in the water in the pool body, each fertilized egg, the gap provides a growth space for the fertilized eggs on each net piece, enhances the survival rate of the fertilized eggs, enables the fertilized eggs to successfully hatch into fish fries in the pool body, and greatly improves the hatchability of the fish fries; the rectangular pool body is convenient for workers to uniformly throw the fish food to the middle part of the pool body along the width direction of the pool body for fish fry to eat, and the rectangular pool body is more practical; the whole operation process is simple under the matching action of the telescopic rod, the positioning rod, the connecting piece and the net piece, and is convenient for workers to operate and use.

The utility model discloses further set up to: the connecting piece includes the connecting block with locating lever sliding connection and the couple that links to each other with the connecting block, and the net piece links to each other with the couple.

Through adopting above-mentioned technical scheme, because the size of cell body is general all bigger, the workman is whole to slide to one side of locating lever with the connecting block, then the workman links to each other the back with the couple on net piece and the connecting block, can promote the connecting block and slide along the locating lever, the slip that the net piece can follow the connecting block moves to suitable position, need not the workman and make a round trip to walk to set up the net piece in suitable position, just can be with net piece evenly distributed in the cell body, and because the existence of connecting block, can automatic certain space of keeping between the net piece, need not the workman to go the adjustment again, the installation of net piece has further been simplified, time is saved, the installation effectiveness of net.

The utility model discloses further set up to: the edge of net piece is equipped with the locating frame, and the net piece is nylon net and the net piece is taut, is equipped with the through-hole that supplies the couple to pass on the locating frame.

By adopting the technical scheme, the net sheets are required to be cleaned before or after being reused, the nylon net is selected to manufacture the net sheets, workers can conveniently clean the net sheets, the nylon net belongs to flexible substances and cannot damage fertilized eggs or fish fries, and the positioning frame is arranged to keep the net sheets in a stretched state, so that the fertilized eggs can be uniformly smeared and distributed on the net sheets; the positioning frame is connected with the hook through the through hole, and the hook is prevented from scraping the net piece.

The utility model discloses further set up to: a certain gap is arranged between the positioning frame and the side wall of the tank body.

Through adopting above-mentioned technical scheme, consider that after the embryonated egg hatches into fry, the fry can move about in the cell body, in order not to hinder the play of fry, consequently the lateral wall of locating frame and cell body need keep the distance, supplies the fry to move about back and forth, and the fry moves about back and forth also can strengthen the activity of fry itself, and the survival rate of fry also can change highly for the fry can grow healthily.

The utility model discloses further set up to: the positioning rod is provided with a pull handle.

Through adopting above-mentioned technical scheme, the setting of pull handle is for making things convenient for the workman toward the direction pulling locating lever of keeping away from the cell body, makes the telescopic link extension drive the locating lever and moves towards the cell body outward to subsequent workman installs the net piece.

The utility model discloses further set up to: the telescopic rod is provided with a limiting part.

Through adopting above-mentioned technical scheme, when the telescopic link extension impeld the locating lever to arrange in the cell body outside, a plurality of net pieces link to each other with the connecting piece, and the gravity of net piece is exerted on the locating lever entirely, and the locating lever will transmit this gravity for the telescopic link, in order to prevent that the telescopic link net piece from not having installed before, shortens under the effect of this gravity, leads to the locating lever to descend to set up the locating part, the motion of restriction telescopic link prevents the emergence of the unexpected condition.

The utility model discloses further set up to: the telescopic rod and the pool body are detachably fixed.

Through adopting above-mentioned technical scheme, when not needing, the telescopic link can be taken out from the cell body.

The utility model discloses further set up to: the telescopic rod and the positioning rod are stainless steel rods.

Through adopting above-mentioned technical scheme, because telescopic link and locating lever expose outside for a long time to telescopic link and locating lever can enter into the aquatic in the cell body, consequently choose for use the stainless steel pole to make telescopic link and locating lever, then telescopic link and locating lever can not rusty, produce harmful effects to the quality of water in the cell body, have ensured the healthy growth of embryonated egg and fry in the cell body.

To sum up, the utility model discloses a beneficial technological effect does:

1. After the sticky oosperms are uniformly coated on the net piece, the net piece moves into the pool body under the matching action of the telescopic rod, the positioning rod and the connecting piece, so that the oosperms can be fully contacted with water in the pool body, the activity and the survival rate of the oosperms are improved, the oosperms can be smoothly hatched into fish fries, the hatchability of the fish fries is improved, the whole process is simple, and the operation and the use of workers are convenient;

2. Connecting block and locating lever sliding connection, net piece and couple continuous back, workman sliding connection piece can remove the net piece to suitable position to the existence of connecting block can make and keep certain space between the net piece automatically, and the net piece can distribute in the cell body uniformly, and the space is provided fertilized egg growth space, and the installation of whole net piece need not the workman and makes a round trip to walk the position of adjustment net piece, has saved the time, also makes things convenient for the workman to install the net piece.
