Example two:
because the crushed fodder particles after impact and the complete fodder are mixed together, the quantity of the complete fodder particles after impact can be conveniently counted and cleaned after the crushed fodder particles and the complete fodder particles are separated, and the operation is troublesome. In this embodiment, therefore, a separating device is also included, arranged at the bottom of the impingement tube 14, which comprises a second motor 30 and a separating plate 31, a separation plate 144 is arranged in the impact tube 14, the separation plate 144 and the bottom wall and the side wall of the impact tube 14 enclose an installation cavity 141, the second motor 30 is arranged in the mounting cavity 141, an output shaft of the second motor 30 passes through the isolation plate 144 and is connected to the separation plate 31, the isolation plate 144 and the side wall of the impact tube 14 enclose a crushed material cavity 142, an output shaft of the second motor 30 is in dynamic sealing connection with the isolation plate 144, to prevent the crushed material from entering the installation cavity 141, the separation plate 31 is in the shape of a disk, the impact tube 14 is in the shape of a cylinder, the outer diameter of the separation plate 31 is the same as the inner diameter of the impact tube 14, a plurality of through separation holes 312 are formed in the separation plate 31, and the diameter of each separation hole 312 is smaller than the minimum outer diameter of the feed particles.
The fodder granule after the striking falls on separation plate 31 at the action of gravity, and the portion of gripping 11 is provided with the switch that whether control second motor 30 rotated, and second motor 30 drives separation plate 31 when rotating and rotates, and kibbling fodder granule gets into crushed aggregates chamber 142 through separation hole 312, and complete fodder granule is because the diameter is big than separation hole 312's diameter, consequently can not fall to crushed aggregates chamber 142, has realized crushed aggregates and complete fodder granule's autosegregation.
In order to collect complete feed particles conveniently, when the separation plate 31 rotates, the feed particles are thrown to the peripheral side under the action of centrifugal force, so that the collection cavity 143 is formed in one side of the impact tube 14, the bottom wall of the collection cavity 143 is flush with the upper end face of the separation plate 31, the feed particles still contact with the separation plate 31 when impacting the side wall of the impact tube 14 and can be continuously driven by the separation plate 31, when the feed particles move to the collection cavity 143, the feed particles move to the collection cavity 143 under the action of centrifugal force, and the bottom wall of the collection cavity 143 is hinged to the side wall of the collection cavity 143 and can be opened downwards, so that the complete feed particles can be taken out conveniently.
Because the separation plate 31 rotates, easily with the partly kibbling fodder granule together get rid of to collect chamber 143, consequently be in the undercut arc portion 311 has been seted up to the upper end of separation plate 31, the quality of complete fodder granule is great, the centrifugal force that receives is also great, the arc portion 311 of undercut makes the fodder granule need enough big quality just can be thrown away, can make the fodder granule after the breakage not enough thrown away, consequently broken fodder granule can fall to crushed aggregates chamber 142 through separation holes 312, and complete fodder granule is because the quality is great, centrifugal force is enough to throw it off and fall to collecting chamber 143, consequently can avoid the crushed aggregates to be thrown away together and collect chamber 143.
In order to facilitate taking out the crushed aggregates, a discharge port is formed in the side wall of the crushed aggregate cavity 142, and a baffle is arranged at the discharge port.
The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
