[0018] For the convenience of description, only parts related to the embodiments of the present utility model are shown.

[0019] Combined with Figures 1-4As shown in the figure, the feed grinding device includes a machine platform 1. A material seat 2 is provided on the side wall of the machine platform 1. A die seat 3 is arranged inside the material seat 2. A feed hopper 4 communicating with the die seat 3 is provided on the side wall of the material seat 2. A discharge port 5 is opened at the bottom of the material seat 2. A circle of discharge holes 6 is opened on the die seat 3. A grinding mechanism is arranged inside the die seat 3. The grinding mechanism includes a convex shaft 7 rotatably installed inside the die seat. A pair of inner and outer triangular plates are arranged on the convex shaft 7. Among them, the inner triangular plate is marked as 81, and the outer triangular plate is marked as 82. The inner triangular plate 81 is fixedly installed. The outer triangular plate 82 is located at the stepped position of the convex shaft and is locked by a locking assembly. Positioning holes 9 are opened at the triangular positions of the inner triangular plate 81. Grinding wheels 10 are arranged at the triangular positions between the inner and outer triangular plates. The inner end of the shaft rod 11 of the grinding wheel 10 is located in the positioning hole, and the outer end passes through the outer triangular plate 82. A limiting mechanism is provided on the outer triangular plate 82 corresponding to each shaft rod 11. A driving motor 12 for driving the convex shaft to rotate is arranged on the machine platform.

[0020] In the existing aquaculture field, before feeding aquaculture animals, it is necessary to use a grinding device to grind the feed to facilitate the animals' eating and digestion. Especially in the fish farming field, compared with other feeds, fish feed requires finer raw material powder particles and needs to be ground before feeding.

[0021] When it is necessary to use this grinding device to grind the feed, first pour a certain amount of feed from the feed hopper. The feed falls from the feed hopper into the die seat. At the same time, the grinding mechanism starts to work to grind the feed in the die seat. The ground feed is discharged from the discharge holes into the material seat and finally flows out through the discharge port. The area between the material seat and the die seat constitutes the discharge interval. The ground feed is discharged from the discharge holes into the discharge interval and finally flows out from the discharge port.

[0022] When the grinding mechanism starts to work, first the driving motor drives the convex shaft to rotate. Driven by the convex shaft, the inner and outer triangular plates rotate synchronously, and the three grinding wheels rotate along the inner wall of the die seat, so as to achieve the purpose of grinding the feed. This device uses three grinding wheels to grind the feed in the die seat at the same time, and the grinding efficiency is relatively high.

[0023] In this structure, combined with Figure 4 , the locking assembly includes a short shaft 13 formed on the convex shaft 7. A locking nut 14 for abutting against the outer triangular plate 82 is screwed onto the short shaft 13. A stirring assembly is arranged on the short shaft 13.

[0024] The grinding wheel can be disassembled from the grinding mechanism, which facilitates a series of subsequent work such as replacement and maintenance. In this device, since the feed hopper is installed on the feed base by bolts. When the grinding wheel needs to be disassembled, first remove the feed hopper, then loosen the locking nut, hold the grinding wheel, and at this time, remove the outer triangular plate from the convex shaft. After the outer triangular plate is removed, the grinding wheels can be taken out from the positioning holes one by one.

[0025] In this structure, in combination with Figure 2 , Figure 4 , the short shaft 13 is of a hollow structure, an internal thread is formed on the inner wall of the short shaft 13, the stirring assembly includes a fixing nut 18, after a U-shaped stirring paddle 19 is inserted through the fixing nut 18, the fixing nut is screwed into the inner wall of the short shaft and locked. And the stirring paddle is arranged towards the feed hopper.

[0026] When a certain amount of feed is poured from the feed hopper, at this time the grinding mechanism can work. When the grinding mechanism starts to work, the convex shaft rotates, the grinding wheels grind the feed, and at the same time the stirring paddle also rotates synchronously to stir the feed. The stirring paddle can break up a small amount of agglomerated feed to improve the quality of feed grinding. When the grinding wheel needs to be disassembled, first remove the stirring paddle. When removing the stirring paddle, only need to loosen the fixing nut, and the whole process is relatively simple.

[0027] As a preferred structure, a pair of cross-section grooves 15 are formed at the outer end of each shaft rod 11, the limiting mechanism includes a limiting plate 16 inserted into the outer end of the shaft rod, an arc-shaped groove 17 is formed on the limiting plate 16, and a plurality of limiting nuts (not shown in the figure) are inserted into the arc-shaped groove 17, and the limiting nuts are screwed into the outer triangular plate and locked.

[0028] In this structure, the limiting mechanism is mainly to prevent the grinding wheel from rotating automatically when grinding the feed, thus affecting the grinding effect. And the structure of the limiting mechanism is relatively simple. The limiting mechanism includes a limiting plate, and a limiting groove matching with the outer end of the shaft rod is formed on the limiting plate. After the installation of the grinding wheel is completed, move the limiting plate towards the outer end of the shaft rod. After the outer end of the shaft rod passes through the corresponding limiting groove, then insert a plurality of limiting nuts into the arc-shaped groove, and the limiting nuts are screwed into the outer triangular plate and locked.

[0029] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
