[0017] like Figure 1-3As shown, the utility model provides a quantitative collection device suitable for floodplain fish resources, comprising a fish driving device 1, a fish collecting device 2 and a telescopic rod connected between the fish driving device 1 and the fish collecting device 2, the fish driving device 1 and the fish collecting device 2 are both rectangular frame structures, the fish driving device 1 and the fish collecting device 2 are both arranged with nets except for the opposite side walls, the end of the fish collecting device 2 away from the fish driving device 1 is fixedly connected with a collecting bucket 3, the large diameter end of the collecting bucket 3 is connected to the fish collecting device 2, the small diameter end of the collecting bucket 3 is detachably connected with a blocking bottle 4, and the side wall of the collecting bucket 3 is provided with a net.

[0018] When collecting fish resources on the floodplain, the fish driving device 1 and the fish aggregator 2 are fixed on the floodplain, and a certain distance is kept between the fish driving device 1 and the fish aggregator 2, and the fish resources are quantitatively collected after they swim between the fish driving device 1 and the fish aggregator 2 and enter the inside. In order to increase the amount of fish entering, fish bait can also be placed in the fish driving device 1 and the fish aggregator 2.

[0019] The fish chasing device 1 is in the form of five-sided nets, which are arranged on the surface of the frame structure. The fish aggregating device 2 is in the form of four-sided nets, with two vacant ends, one of which faces the fish chasing device 1 and the other end is connected to the collecting bucket 3. The fish chasing device 1 is manually pushed to move toward the fish aggregating device 2, so that the fish resources enter the fish aggregating device 2 and finally enter the collecting bucket 3. By removing the sealing bottle 4 connected to the movable end of the collecting bucket 3, the collected fish eggs and excess fish resources are poured out, thereby completing the collection of floodplain fish.

[0020] like Figure 1 and Figure 2 As shown, in order to prevent the collected fish resources from swimming out from between the fish chasing device 1 and the fish aggregating device 2, the telescopic rod comprises a piston rod 7 located in the middle and a first connecting cylinder 5 and a second connecting cylinder 6 slidably mounted on both ends of the piston rod 7, and the first connecting cylinder 5 and the second connecting cylinder 6 are fixedly mounted on the fish chasing device 1 and the fish aggregating device 2, respectively.

[0021] By installing the first connecting tube 5 and the second connecting tube 6 on the fish driving device 1 and the fish collecting device 2, and arranging the piston rod 7 accordingly, the fish driving device 1 and the fish collecting device 2 can have a larger relative moving distance, and the first connecting tube 5 and the second connecting tube 6 can make the relative side walls of the fish driving device 1 and the fish collecting device 2 contact through the contact at the end, thereby realizing the closure of the connection and preventing the fish resources inside from swimming out.

[0022] like Figure 1 and Figure 2 The outer wall size of the fish driving device 1 is the same as the inner wall size of the fish aggregator 2, the first connecting tube 5 is fixed on the outer wall of the fish driving device 1, and the fish aggregator 2 is fixed on the inner wall of the fish aggregator 2. The fish driving device 1 can be moved to the inside of the fish aggregator 2, which can reduce the occupied space during transportation and improve the efficiency of transportation.

[0023] like Figure 1 and Figure 2 As shown. The two ends of the first connecting tube 5 are respectively fixedly connected to the two ends of the fish driving device 1, and the two ends of the second connecting tube 6 are respectively fixedly connected to the two ends of the fish collecting device 2, and the telescopic rods are distributed at the four inner corners of the fish collecting device 2. The first connecting tube 5 and the second connecting tube 6 can not only guide the movement of the fish driving device 1, but also improve the structural strength of the fish driving device 1 and the fish collecting device 2.

[0024] like Figure 3 As shown, in order to facilitate the disassembly and assembly of the piston rod 7, the first connecting tube 5 and the second connecting tube 6 are both provided with guide strips 11 along the axial direction, and the first connecting tube 5 and the second connecting tube 6 are both provided with sliding seats 10 slidably axially, and the threaded through hole in the middle of the sliding seat 10 is threadedly connected with one end of the piston rod 7, and the threads at both ends of the piston rod 7 have the same rotation direction, and the ends of the first connecting tube 5 and the second connecting tube 6 through which the piston rod 7 passes are both provided with stop rings with an inner diameter smaller than that of the sliding seat 10.

[0025] Since it is difficult to ensure that the ground in the use environment is flat, the piston rod 7 will inevitably bend during long-term use, which not only makes it difficult for the fish drive 1 to slide, but also makes it impossible for the fish drive 1 to enter the fish collector 2. Therefore, the piston rod 7 needs to be replaced or repaired in the near future. After the fish drive 1 and the fish collector 2 are pulled apart, the piston rod 7 is rotated to separate one end of the piston rod 7 from a sliding seat 10 in the first connecting tube 5 or the second connecting tube 6, and then the separated part is removed. The piston rod 7 is separated from the other sliding seat by rotating the piston rod 7 in the opposite direction, and the piston rod 7 can be removed, and then the staff can replace or straighten the piston rod 7. The subsequent installation of the piston rod 7 is opposite to the above method.

[0026] like Figure 1 As shown. The blocking bottle 4 includes a fixing seat and a connecting tube. The fixing seat is fixed to the movable end of the collecting bucket 3. The fixing seat is a cylindrical structure, and the interior of the fixing seat is connected to the interior of the collecting bucket 3. One end of the connecting tube is sealed, and the other end is provided with an internal thread that matches the external thread of the movable end of the fixing seat. By unscrewing the connecting tube connected to the fixing seat, the blocking bottle 4 is removed, and the small-sized fish resources in the collecting bucket 3 can be poured out.

[0027] like Figure 1 and Figure 2As shown. A push rod 8 is installed horizontally and rotatably on the top of one end of the fish driving device 1 away from the fish collecting device 2. A limit plate 9 is provided on one side of the rotation axis of the push rod 8. A threaded hole is provided on the push rod 8. A through hole is provided on the limit plate 9 to communicate with the threaded hole when the push rod 8 is in a horizontal state or a vertical downward state. When the fish driving device 1 needs to be pushed, the push rod 8 can be locked in the working state by rotating it to a horizontal state, passing a bolt through the through hole and connecting the threaded hole on the push rod 8; when the push rod 8 is not needed, the push rod 8 is adjusted to a vertical downward state, and then locked by a bolt to achieve the storage of the push rod.
