The position of the remote control floating boat 8 is controlled by the controller 12, thereby increasing the feeding range of the bait throwing machine. At the same time, the height of the remote control floating boat 8 and the water surface remains stable, thereby better controlling the feeding height and distance and improving the feeding effect.

[0051] Embodiment three, as Fig.11 As shown, in this embodiment, on the basis of the second embodiment, a retractable discharging telescopic sleeve 9 is further provided between the discharging barrel 6 and the discharging hose 73, and the discharging telescopic sleeve 9 includes a first discharging sleeve 91, a second discharging sleeve 92, a third discharging sleeve 93 and a fourth discharging sleeve 94 which are sequentially sleeved and connected from the inside to the outside, and a spiral guide groove 61 is also provided on the inner walls of the first discharging sleeve 91, the second discharging sleeve 92, the third discharging sleeve 93 and the fourth discharging sleeve 94, and the first discharging sleeve 91 and the fourth discharging sleeve 94 are respectively connected to the discharging barrel 6 and the discharging hose 73, and the fourth discharging sleeve 94 is also sleeved with a sleeve fixedly connected thereto. A retractable sleeve guide rod 96 is also connected between the fixed block 95 and the frame 1. The sleeve guide rod 96 includes a first set of rods 961, a second set of rods 962, a third set of rods 963 and a fourth set of rods 964 which are sequentially sleeved and connected from the inside to the outside. By adding a discharging telescopic sleeve 9 between the discharging barrel 6 and the discharging hose 73, the length of the discharging hose 73 is shortened when the distance between the remote control floating boat 8 and the frame 1 remains unchanged, thereby avoiding the discharging hose from falling in the middle due to the length of the discharging hose being too long, thereby reducing the discharging speed of the bait at the discharging port structure 72 and affecting the feeding distance and accuracy. The sleeve guide rod 96 plays an auxiliary supporting role for the discharging telescopic sleeve 9.

[0052] On the other hand, the present invention provides the following technical solution: a method for using a pneumatic bait thrower for a seedling pond, comprising using the above-mentioned pneumatic bait thrower for a seedling pond to feed bait.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
