A lock catch 13 is further fixedly arranged between the bin 1 and the top shell 21, and the lock catch 13 and the opening and closing blade 12 can cooperate to fix the bin 1 on the top shell 21. Through the arrangement of the opening and closing blade 12 and the lock catch 13, the bin 1 can be opened in the direction away from the top shell 21, which is convenient for the operator to clean the bin 1. The bin 1 is arranged as a cylindrical storage container, and a bin upper cover 11 is installed at the top of the bin 1. The operator can pour bait into the bin 1 in advance and install the bin upper cover 11 at the top of the bin 1. A scale is formed on the side wall of the bin 1, and the operator can quantitatively pour bait into the bin 1 according to the scale.

[0039] Referring to Figure 3 and Figure 4 The top shell 21 is divided into a top shell upper end 213 and a top shell lower end 214. A cavity is formed in the inside of the top shell upper end 213 to form a distribution bin 22, and the distribution bin 22 is arranged in communication with the inside of the bin 1. The inside of the top shell lower end 214 is arranged as a cavity structure and rotatably arranged with a distribution roller 221. The top shell lower end 214 and the distribution roller 221 are arranged in shape matching, thereby helping to reduce the gap between the top shell lower end 214 and the distribution roller 221, preventing bait from passing through the gap, and ensuring that the equipment can quantitatively feed bait. The distribution roller 221 is arranged as a cylinder, and a plurality of grooves are formed on the surface of the distribution roller 221 along the axial direction to form distribution grooves 222. In the embodiment of the utility model, the distribution grooves 222 are specifically arranged as four. The distribution bin 22 is arranged as a funnel shape with the upper end being large and the lower end being small. This arrangement can guide bait and make the bait gather in the direction of the distribution grooves 222. A distribution motor 212 is arranged on the outside of the top shell 21. The distribution motor 212 is fixedly arranged on the top shell 21 through bolts. The output shaft of the distribution motor 212 extends into the top shell 21 and is detachably connected with the distribution roller 221. The distribution motor 212 can drive the distribution roller 221 to rotate when started. A distribution roller outer cover 211 is arranged on the side of the top shell 21 away from the distribution motor 212. Referring to Figure 1 and Figure 3The top shell 21 is detachably connected with the distribution roller outer cover 211, and the top shell 21 is provided with a through hole at the end away from the distribution motor 212. When the distribution roller outer cover 211 is mounted on the top shell 21, the distribution roller outer cover 211 can completely cover the through hole at the end of the top shell 21 away from the distribution motor 212, thereby sealing the distribution roller 221. Different types of distribution rollers 221 can be replaced by detaching the distribution roller outer cover 211. The top shell 21 is provided with an intermediate shell 33 at the end away from the bin 1. The intermediate shell 33 is internally provided with a cavity, and is further provided with a partition plate 335. The partition plate 335 is integrally arranged with the intermediate shell 33, and divides the intermediate shell 33 into a dropping bin 336 and a motor bin 338. The motor bin 338 is internally fixedly provided with a throwing motor 331. The dropping bin 336 is in communication with the distribution bin 221. When the bait is placed in the bin 1, the bait can fall into the distribution chute 222. The distribution motor 212 drives the distribution roller 221 to rotate, and the bait in the distribution chute 222 is thrown from the bin 1 into the dropping bin 336, thereby realizing quantitative feeding of the bait. The dropping bin 336 is provided with a fixed flange 334. The fixed flange 334 is provided with two opposite fixed flanges 334. The fixed flange 334 is provided with a threaded hole. The fixed flange 334 is fixedly connected with a connecting flap 333 through a bolt. The connecting flap 333 is a rectangular flap formed by bending. The connecting flap 333 is provided with two connecting flaps 333. The connecting flaps 333 are fixedly arranged on the fixed flange 334 through a bolt. The other end of the connecting flaps 333 extends outward from the dropping bin 336 and is fixedly connected with the outer surface of the top shell 21 through a bolt, so that the intermediate shell 33 and the top shell 21 are connected as a whole. The two connecting flaps 333 are opposite to each other and are bent. An upper wide and lower narrow shape is formed between the two connecting flaps 333. When the bait passes through, the falling route of the bait can be more concentrated. The connecting flap 333 is fixedly connected with a speed regulator fixed plate 337 through a bolt. The speed regulator fixed plate 337 is fixedly connected with a speed regulator 332 through a bolt. The speed regulator 332 is electrically connected with the throwing motor 331. The speed regulator 332 can adjust the rotating speed of the throwing motor 331. The speed regulator 332 is fixed through the speed regulator fixed plate 337 and the connecting flap 333. Through the arrangement of the speed regulator fixed plate 337 and the connecting flap 333, the adverse effects of the rotation and vibration of the throwing motor 331 and the distribution motor 212 can be reduced.

[0040] The bottom of the intermediate shell 33 is fixedly provided with a bottom shell 34, which is fixedly connected with the intermediate shell 33 by bolts, and the throwing bin 344 is communicated with the falling bin 336.

A plurality of throwing blades 32 are fixedly arranged on the throwing disc 31. The throwing motor 331 can drive the throwing disc 31 to rotate. When the bait falls, the falling route of the bait can be gathered to the direction of the throwing blades 32 by the connecting flaps 333, so that the bait falls on the throwing blades 32. The throwing blades 32 rotate to drive the bait to rotate. The centrifugal force generated by the rotation of the throwing blades 32 can throw the bait outward.

[0041] With reference to Figure 5 The bottom of the bottom shell 34 is provided with a bottom plate 345, and a handle nut 341 is fixedly arranged on the bottom plate 345. The bottom plate 345 is fixedly arranged on the bottom shell 34 through the handle nut 341. The handle nut 341 can realize the detachable function of the bottom plate 345. This arrangement facilitates the operator to clean the clogging or clean the throwing disc 31 when the throwing disc 31 is clogged. An adjustable baffle 342 is arranged between the bottom shell 34 and the bottom plate 345. The adjustable baffle 342 is slidably arranged on the bottom shell 34. The adjustable baffle 342, the bottom shell 34 and the bottom plate 345 jointly form a discharge port 346. The sliding adjustable baffle 342 can change the direction of the discharge port 346. A rubber fixing plug 343 is installed on the bottom shell 34. After the direction of the discharge port 346 is adjusted, the position of the adjustable baffle 342 can be fixed by the rubber fixing plug 343.

[0042] The implementation principle of embodiment 1 is as follows: the operator can guide the bait into the bin 1, install the bin upper cover 11 on the top of the bin 1, and adjust the direction of the discharge port 346 by sliding the adjustable baffle 342. After starting the equipment, the bait in the falling chute 222 is thrown onto the throwing disc 31 by the rotation of the baiting roller 221 driven by the baiting motor 212. The throwing disc 31 is driven to rotate by the throwing motor 331. The throwing disc 31 drives the throwing blades 32 to rotate. The bait is thrown outward through the discharge port 346 by the centrifugal force of the rotation of the throwing disc 31 and the throwing blades 32. The speed of the rotation of the throwing motor 331 is adjusted by controlling the speed regulator 332 to change the centrifugal force of the rotation of the throwing disc 31 and the throwing blades 32, so as to control the throwing distance of the bait.
