Detailed Description
The invention will be further explained with reference to the drawings.
As shown in fig. 1 to 5, the invention comprises a bait box and an electric lifting device, wherein the top of the electric lifting device is provided with a joint 11, and as shown in fig. 5, the electric lifting device is fixed with the bait box through the joint 11. As shown in figures 1 and 2, the bait box is cylindrical and plays a role in containing and recovering baits, the bait box is made of glass fiber reinforced plastic which is not easy to corrode and is environment-friendly, the diameter of the bait box is 1.2-1.8m, and the total height of the bait box is 2-2.5 m. The top of the bait box is provided with a screen door controller 1 which can control the opening and closing of a screen door 4, the bottom of the bait box is provided with a bottom plate 6, the middle of the surface of the cylindrical body of the bait box is provided with the screen door 4, the height of the screen part is 1.2-1.5m, the screen door 4 is in sliding connection with a slide rail 2 on the bait box, and the distance between the screen door 4 and the bottom plate 6 is enough to block bait, so that fish can conveniently enter and exit. The top of the mesh door 4 is provided with an elastic upper inner net 3, the bottom of the mesh door is provided with an elastic lower inner net 5, and the effect of driving fish schools can be realized under the action of elastic force. The screen door 4 and the elastic upper and lower inner nets of the bait box are made of fine screen gauze, and the aperture of the screen gauze is smaller than the bait with the minimum volume. The middle of the bottom plate of the bait box is designed to be convex, so that the lifting rod joint 11 can be conveniently inserted, and the lifting rod can lift together under the action of the lifting controller 9, thereby realizing two states of feeding the bait when the bait box is sunk into water and recovering the residual bait on the water surface.
The electric lifting device comprises a first-stage lifting rod 8 and a second-stage lifting rod 7, the lifting rods have enough length and can stretch out and draw back well, the bottom of the first-stage lifting rod 8 is connected with a lifting controller 9, and a battery 10 is arranged in the lifting controller 9, so that remote control is realized conveniently. The lifting rod is made of stainless steel materials which are light and thin and are not easy to corrode, the height of the first-level lifting rod 8 is 2-2.5m, and the diameter is 0.35-0.4 m; the height of the secondary lifting rod 7 is 1.5-2m, the diameter is 0.3-0.35m, the secondary lifting rod has enough stability and enough height to drive the bait box to the required depth in the water; the lifting controller 9 is made of a waterproof material, and is easy to maintain and maintain.
When the device works, an operator installs the electric lifting device at a fixed position in a pond, the bottom plate 6 of the bait box is connected with the electric lifting device through the joint 11 on the lifting rod, and two states of sinking the bait box into water and floating the bait box on the water surface are realized under the action of the lifting controller 9. When the bait casting operation, the bait case stretches out the surface of water under the impetus of lifter, and remote control electric lift device makes after packing into the bait case with bait and sinks to suitable degree of depth under, and the water gets into the bait case through gauze door 4 for light bait suspends in the box top, and heavy bait then sinks on bottom plate 6, and gauze door 4 is opened in the remote control this moment, supplies fish to swim into edible bait, as shown in fig. 3. Treat after feeding the fish, control elasticity upper and lower intranet, make it slowly be close to, wait for the fish to swim out the back from the box both sides under the effect of this slight extrusion force, as shown in fig. 4, screen door 4 is closed in the remote control, control elasticity upper and lower intranet makes it resume to the original condition, and the remote control lifter makes bait case slowly float out of the water surface this moment, and the water is discharged from the screen, and the bait that is not eaten falls back in bottom plate 6, and the staff retrieves remaining bait and clears up the device of feeding.
The using method of the invention comprises the following steps:
and 6, recovering the residual baits in the bait box by the workers, and thoroughly cleaning the bait box for the next use.
