The driving device comprises a diesel engine 10 (which is a power source of the whole soft-shelled turtle catching device), an oil tank 11 (filled with hydraulic oil), a hydraulic pump 12, a control valve 13, an oil pipe 14, a driving hydraulic motor 15, a driving impeller 16, a driven impeller 17, a rear handle 18 and a rear upright post 19; the hydraulic pump 12 is connected with an output shaft of the diesel engine 10; the hydraulic pump 12, the control valve 13, the driving hydraulic motor 15, the liquid extracting hydraulic motor 6 and the oil tank 11 form a closed loop through a plurality of oil pipes 14, and the driving hydraulic motor 15 and the liquid extracting hydraulic motor 6 are connected in parallel; the output shaft of the driving hydraulic motor 15 is connected with a driving impeller 16; at least two driven impellers 17 are respectively arranged at two sides of the frame body 1; the lower end of the rear upright post 19 is connected with the upper end of the frame body 1, and the upper end of the rear upright post 19 is hinged with the middle part of the rear handle 18 through another hinge ball 20; the rear handle 18 is connected at its distal end to the drive hydraulic motor 15.
The hydraulic pump 12 drives the extracting liquid pressure motor 6 to work, the output shaft of the extracting liquid pressure motor 6 rotates to drive the extracting main shaft 5 positioned in the extracting pipe 2 to rotate, so that the extracting impeller 4 rotates along with the extracting impeller 4, when the bucket 3 is inserted into slurry or water, the frame body 1 continuously advances, if a soft-shelled turtle is arranged in the bucket 3, the soft-shelled turtle is extruded by the slurry or the water to enter the front end of the extracting pipe, once the soft-shelled turtle meets the extracting impeller 4, the soft-shelled turtle is under the action of the extracting impeller 4, the soft-shelled turtle is continuously lifted until the soft-shelled turtle falls out from the rear end or the leakage opening of the extracting pipe 2, and slurry or mud possibly enters the extracting pipe 2 along with the soft-shelled turtle in the lifting process, and under the extrusion and mesh opening effects of. The edge of the extraction impeller 4 is abutted against the inner wall of the extraction pipe 2 or the distance between the edge and the inner wall is less than 5 cm. This can achieve a better extraction result.
When the direction needs to be turned, the direction of the driving impeller 16 at the tail end of the rear handle 18 can be changed by operating the rear handle 18, so that the direction of the driving force received by the frame body 1 is changed, and the turning operation is realized. To extend the range of adjustability, the front 7 and rear 19 uprights may be telescopic rods.
As shown in fig. 4, the extraction pipe 2 can be swung by the front handle 9 to adjust the orientation of the bucket 3 by the action of the articulated ball 20, so that a wider fishing range can be obtained; the direction of the driving impeller 16 can be regulated and controlled by the swinging rear handle 18, so that the moving direction and the moving speed of the driving frame body 1 are driven, the whole soft-shelled turtle fishing device has strong maneuverability and can be operated by only one person or two persons.
In order to better collect the extracted soft-shelled turtles, a collection basket 21 with an open upper end is also arranged at the upper end of the frame body 1; the side walls and bottom of collection basket 21 are provided with mesh openings. The mesh is convenient for the discharge of mud or muddy water. In order to ensure the cleanness of the extracting liquid pressure motor 6 and prevent the soft-shelled turtle from being hurt, the upper end of the extracting pipe 2 is provided with a leak opening which is arranged towards the upper end of the frame body 1; the collection basket 21 is positioned below the leakage opening, when the soft-shelled turtle is lifted upwards by the extraction impeller 4 in the extraction pipe 2, the soft-shelled turtle falls into the collection basket 21 below the leakage opening after encountering the leakage opening, and actually, the leakage opening can be set as low as possible under the condition of less sediment, but if the mud is more, the leakage opening is set as far as possible from the bucket 3 in order to discharge the unnecessary mud as much as possible, so as to extrude the excessive mud from the mesh openings; therefore, the arrangement of the leakage opening can be movable or adjustable, for example, the whole extraction pipe 2 is provided with a plurality of openable cover sheets facing the lower side of the frame body 1, and the leakage opening can be formed by opening the cover sheets, so that the selection of the leakage opening position can be realized by opening the cover sheets at different positions.

The other end of the water outlet pipe can control the water outlet direction thereof through manual operation, and can also be fixed at a certain position, such as the extraction pipe 2, thereby simplifying the operation; because the soft-shelled turtle is usually raised artificially in the pond, consequently, water washing unit need not be equipped with the water tank alone, directly with the water pump place support body 1 below can, the water pump can extract the water in the pond and wash support body 1 or collection basket 21 or extraction tube 2.
In order to reduce the weight and improve the cleaning effect, the extraction main shaft 5 is a hollow pipe structure, and the side wall of the extraction main shaft is provided with a plurality of water outlet holes. An auxiliary device connected with a water outlet pipe of the water washing device can be arranged at the tail end of the extraction main shaft 5, for example, the auxiliary device comprises a bearing sleeved on the extraction main shaft 5 and a rubber sleeve arranged outside the bearing, the rubber sleeve is positioned outside the extraction pipe 2 and used for sleeving a water outlet pipe for fixing the water washing device, specifically, one end of the water outlet pipe is connected with a water pump, and the other end of the water outlet pipe is inserted into the extraction main shaft 5 after passing through the rubber sleeve, so that water used for washing by the water washing device is poured into the extraction main shaft 5 and is discharged from a water outlet hole of the extraction main shaft 5, and the extraction pipe 2 is washed from inside to outside, and the washing effect is better than that from outside to inside; the auxiliary device has the advantages that when the extraction main shaft 5 rotates, the water outlet pipe rotates around the extraction main shaft 5 but cannot be wound, and smooth water outlet is guaranteed.
It should be noted that the material of the frame body 1 or the area thereof should satisfy the corresponding buoyancy condition, so that the whole turtle catching device floats on the water surface without sinking. It is preferable that the frame body 1 has a hull shape.
