Description

Technical Field

[0001] The utility model relates to the technical field of game equipment, in particular to a fish catching device. Background Art

[0002] Chinese utility model patent CN2022236056796 discloses a novel fish catching machine, comprising a chassis, a fish catching mechanism and a moving mechanism. The fish catching mechanism comprises a fish catching rod, a lifting mechanism for driving the fish catching rod to rise and fall, and a fish catching net installed at the lower end of the fish catching rod. The rear portion of the fish catching net is provided with a mounting portion, which is mounted at the lower end of the fish catching rod through a rotating shaft. The fish catching net can rotate between a fish catching state and a fish dumping state. The fish catching rod is also provided with an elastic member that enables the fish catching net to maintain the fish catching state in the absence of external force. A rearward extending pressure rod is connected to the mounting portion of the fish catching net, and a net opening top rod is provided in the fish dumping area. When the fish catching net is lowered into the fish dumping area, the net opening top rod presses under the pressure rod to drive the fish catching net to rotate to the fish dumping state. When the fish catching mechanism is used to dump fish, the top rod of the net needs to be pushed under the pressure rod to dump the fish. The pressure rod position accuracy is relatively high. If the pressure rod deviates from or detaches from the top rod of the net, the fish cannot be dumped. At the same time, the moving mechanism adopts the optical axis pulley and the optical axis to cooperate. The clearance between the optical axis pulley and the optical axis cannot be adjusted, resulting in the optical axis pulley and the optical axis needing higher precision to cooperate, which invisibly increases the manufacturing difficulty.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments, wherein the same components are represented by the same reference numerals.

[0025] Example 1

[0026] See also Figure 1 and Figure 2 The embodiment of the present invention provides a fish catching device, including a three-axis moving module 100 and a fish catching mechanism 200. The three-axis moving module 100 drives the fish catching mechanism 200 to move along the X, Y, and Z axes.

[0027] In this embodiment, the three-axis moving module 100 can be a mature XYZ three-axis module in the existing technology, and can also adopt the moving mechanism in Chinese utility model patent CN2022236056796.

[0028] like Figure 2 As shown, the fish scooping mechanism 200 includes a mounting plate 201, a lifting mechanism, a fish scooping net 220, a first rotating joint and a second rotating joint. The mounting plate 201 is assembled on the three-axis movable module 100 and can move along the X, Y and Z axes. The lifting mechanism is fixedly assembled on the upper part of the mounting plate 201. One end of the first rotating joint is fixedly connected to the edge of the fish scooping net 220, and the other end of the first rotating joint is hinged to the lower part of the mounting plate 201. The lower end of the second rotating joint is hinged to the edge of the fish scooping net 220, and the upper end of the second rotating joint is hinged to the lifting part of the lifting mechanism.

[0029] When the fish is caught by the fish catching device of the present invention, the three-axis moving module 100 drives the fish catching mechanism 200 to descend to a preset height. When the fish enters the fish catching net 220, the three-axis moving module 100 drives the fish catching mechanism 200 to rise and leave the water body. Then, the three-axis moving module 100 drives the fish catching mechanism 200 to move to the fish dumping area. The lifting part of the lifting mechanism descends and drives the fish catching net 220 to rotate downward around the hinge point of the first rotating part and the mounting plate 201, so that the fish catching net 220 tilts downward, thereby causing the fish in the fish catching net 220 to fall into the fish dumping area; thereafter, the lifting part of the lifting mechanism rises and drives the fish catching net 220 to rotate upward around the hinge point of the first rotating part and the mounting plate 201, so that the fish catching net 220 is horizontal and can continue to move to catch fish; the fish dumping action and the returning action of the fish catching mechanism 200 are all controlled by the lifting mechanism, and the position error requirement of the fish catching mechanism 200 is low, and there is no need to set up unnecessary precision control parts, which is conducive to reducing the cost of the fish catching device.

[0030] In an embodiment of the present utility model, a first connecting plate 221 is fixed to the edge of the fishing net 220, and the corners of the first connecting plate 221 are rounded. The first rotating part includes a first U-shaped part 230 and a second connecting plate 231. The first connecting plate 221 and the second connecting plate 231 are overlapped and fixedly connected. Specifically, the first connecting plate 221 and the second connecting plate 231 are connected by a combination of multiple screws and nuts. The open end of the first U-shaped part 230 is hinged to the lower part of the mounting plate 201 through a first hinge rod 232, so that the first U-shaped part 230, the first connecting plate 221, the second connecting plate 231 and the fishing net 220 can rotate around the first hinge rod 232.

[0031] In an embodiment of the present invention, the second rotating member includes two hinged plates 240 arranged opposite to each other, the lifting portion of the lifting mechanism is fixedly connected to a second U-shaped member 216 with a lower opening, and the upper surface of the first connecting plate 221 is fixedly provided with a third U-shaped member 222 with an upper opening. The upper ends of the two hinged plates 240 are respectively hinged to the open ends of the second U-shaped member 216 through second hinge rods 241, and the lower ends of the two hinged plates 240 are respectively hinged to the open ends of the third U-shaped member through third hinge rods 242. The two ends of the hinged plate 240 are respectively hinged to the lifting portion of the lifting mechanism and the third U-shaped member 222, so that the lifting portion of the lifting mechanism can be raised and lowered to control the rotation of the first rotating member, thereby driving the fishing net 220 to rotate. The second rotating member has a simple structure and high stability.

[0032] In an embodiment of the present utility model, the lifting mechanism includes a motor 211, a lifting screw seat 213, a lifting rod 214 and a guide seat 215. The guide seat 215 is fixedly arranged in the middle of the mounting plate 201. The lifting rod 214 passes through the guide seat 215 in a lifting manner. The lifting screw seat 213 is fixedly arranged at the upper end of the lifting rod 214. The motor 211 is fixed to the mounting plate 201 through the L-shaped plate 210. The power output end of the motor 211 is fixedly connected to the screw 212 that is screw-driven with the lifting screw seat 213. The lifting rod 214 is connected to the guide seat 215. The screw 212 is coaxially arranged, and the upper end of the second rotating joint is hinged to the lower end of the lifting rod 214. When the motor 211 rotates forward, the motor 211 drives the screw 212 to rotate forward. Since the lifting screw seat 213 can only move up and down but cannot rotate, the screw 212 drives the lifting screw seat 213 to descend when it rotates forward, and then drives the fishing net 220 to rotate downward through the second rotating joint. Conversely, when the screw 212 rotates reversely, it drives the lifting screw seat 213 to rise, and then drives the fishing net 220 to rotate upward to a horizontal state through the second rotating joint.

The second roller assembly 113 can be moved and locked along the width direction of the slide 111. The guide rail 120 of the X-axis module 110 is provided with guide grooves 121 on opposite sides respectively. The rollers of the first roller assembly 112 and the second roller assembly 113 are respectively placed in a guide groove 121 and rotate in the guide groove 121 as the slide 111 moves.

[0037] Specifically, the X-axis module 110 includes two first roller assemblies 112 and two second roller assemblies 113 , which are symmetrically disposed in the two guide grooves 121 .

[0038] like Figure 4 and Figure 5 As shown, the second roller assembly 113 includes a fixed shaft 114, an adjusting block 115 fixedly mounted on the fixed shaft 114, and a roller 116 rotatably mounted on the fixed shaft 114. The slide seat 111 is provided with a strip-shaped adjusting hole 1111 for assembling the fixed shaft 114, and a top positioning hole 1112 perpendicular to the strip-shaped adjusting hole 112 and corresponding to the adjusting block 115. A top positioning screw (not shown in the figure) is provided in the top positioning hole 1112, and the head end of the top positioning screw abuts against the side wall of the adjusting block 115, so that the top positioning screw forms a lateral support for the adjusting block 115, which can improve the stability of the roller assembly.

[0039] A fishing device of the present invention can change the spacing between the first roller assembly 112 and the second roller assembly 113 by setting the second roller assembly 113 to an adjustable position, and can better adapt to the guide groove 121, thereby improving the service life of the moving assembly of the X-axis module 110.
