Furthermore, the inserted bar is the conical spring structure, and the lower extreme diameter of inserted bar is less than the upper end, the lower extreme tip of inserted bar has sharp-pointed plug.

The principle of the bait feeding mechanism is as follows: because the feeding step surface is higher than the water inlet step surface, and the water inlet step surface is higher than the mixing step surface, when the positioning rod is abutted against the feeding step surface, the distance between the rotary table and the mixing cylinder is the largest, the position of the piston in the mixing cylinder is the smallest closed volume of the mixing cylinder, and similarly, when the positioning rod is positioned at the mixing step surface, the closed volume in the mixing cylinder is the largest, and when the positioning rod is positioned at the water inlet step surface, the closed volume in the mixing cylinder is between the largest and the smallest; gear motor slowly rotates, and the locating lever loops through feeding step face, water inlet step face, compounding step face and direction inclined plane, so circulation, the state that corresponds the branch feed cylinder does in proper order: the material distributing cylinder pushes the material discharging wheel to feed materials in a rotating way; the water inlet gap on the material separating barrel corresponds to the water inlet hole so as to lead the material mixing barrel to feed water; stirring the mixture of the bait and the water under the condition that the feed distributing cylinder blocks the water inlet and is separated from the feed discharging wheel; the piston moves rapidly to compress the mixing cylinder when the positioning rod passes over the guide step, and the plug opens the material spraying hole to spray the mixture out of the mixing cylinder.

The basic principle of the bait feeding mechanism is as follows: the bait can be discharged only in the process that the discharging wheel is pressed and rotated by the outer wall of the material distributing cylinder, namely the bait enters the mixing cylinder through the charging bucket; in the processes of water feeding and material feeding, the compression spring is in a compression state, and in the process that the positioning rod passes over the guide inclined plane, the mixed material can be sprayed out due to the fact that the material pressure in the mixing cylinder increases suddenly and the compression spring is in a state of minimum compression force; in the processes of water feeding and material mixing, the material separating barrel is separated from the discharging wheel; in the mixing and feeding processes, the water inlet hole is always in a state of being blocked by the material distributing cylinder; the feeding avoiding part is a notch on the material distributing barrel, and when the position is aligned to the material distributing wheel, the material distributing wheel cannot rotate due to the fact that the material distributing wheel cannot be in contact with the material distributing barrel, and the material discharging is suspended.

This bait feeding mechanism can realize advanced bait, the short time of again intakes, then the blowout misce bene, throws the in-process storage bucket of material under water and can not intake, has solved the problem that can't throw out bait under water at a high speed, throws the mode of material after the misce bene, has increased the bait and has thrown the scope of delivering, drops into the bait of set amount in the time of setting for and replaces manual work.

Walking and anchoring are realized: the driving motor rotates in the positive direction to drive the paddle wheels to rotate, the rotation speeds of the two paddle wheels are different, so that actions such as steering, turning around and the like can be realized, the paddle wheels push water flow to form reverse acting force on the floating plate so as to enable the floating plate to move on the water surface, and the walking speed can be controlled by controlling the rotation speed; driving motor is at the rotatory in-process of drive oar wheel, and the reel is in the power separation state under the effect of the one-way bearing above that, and during driving motor counter rotation, the oar wheel is in the power separation state because of the effect of the one-way bearing above that, and at this moment, driving motor drives the reel rotation, realizes the roll-up to the haulage rope, that is to say: the floating plate is only used for taking the anchor in a state of stopping moving, and the floating plate only runs after the anchor taking is finished, so that the driving motor can be used as a machine for two purposes; it should be noted that: the forward rotation and the reverse rotation are referred to herein only for better illustration of the principles thereof and no specific reference is made thereto.

When the floating plate needs to be positioned on the water surface, the electromagnetic structure is powered off, so that the balancing weight is separated from the floating plate, the balancing weight sinks under the action of the load, the traction rope bears the load to drive the lead curved rod to be pressed, and the position sensor can obtain a signal that the balancing weight does not reach the anchoring position; when the positioning anchor is sunk into the water bottom land, the bearing of the traction rope is reduced, the wire curved rod is reset under the action of the torsion spring, the position sensor can obtain a signal reaching the anchoring position, so that the driving motor stops, the electromagnetic valve is controlled, the driving cylinder is far away from the sleeve, the inner wire is pulled to move in the bearing wire pipe, the free end of the inner wire pulls the driving disc to move upwards in the threaded hole, the mounting block is driven to rotate, and the spiral insertion rod 'drills' into the water bottom land during the rotation of the mounting block, so that the connection of the positioning anchor and the water bottom land is realized; on the contrary, after the electromagnetic valve is powered off, the driving cylinder is close to the sleeve under the action of the return spring, and the mounting block and the inserted bar rotate in opposite directions, so that the inserted bar is screwed out of the underwater ground, and the separation of the positioning anchor and the underwater ground is realized.

Generally speaking, the underwater land is soft soil such as mud flat and the like, the insertion rod is easy to screw in or screw out, and the positioning anchor can be connected with the underwater land due to the existence of the balancing weight.

In order to ensure that the free end of the inner wire does not rotate greatly when the inner wire moves relative to the bearing wire pipe, the mounting block can be driven to rotate by the movement of the free end of the inner wire, two guide wheels in a pressing state are arranged on the balancing weight, an annular groove matched with the inner wire is arranged on each guide wheel, an anti-skid raised line is arranged in each annular groove, the inner wire is arranged between the two annular grooves, and the rotation of the free end of the inner wire is reduced as much as possible in the moving process.

The inner wire and the bearing wire tube are of structures similar to brake wires, the bearing sleeve can ensure that the inner wire has a certain unobstructed moving space inside, and the inner wire and the bearing wire tube do not have tensile properties but have certain bending deformation properties.

Can realize through shape and anchoring that bait throws in the replacement of device input position, the fixed of input position, function such as revetment return, be suitable for throwing in of large tracts of land waters, avoid the extravagant excessive concentration of bait and bait input.

The circuitry and programming necessary to coordinate the various electrical components, drive units and power supplies are well known in the art and are not described in detail herein.
