Detailed Description

The utility model is further described below with reference to fig. 1-3.

The utility model provides a fodder screening separator, includes outer frame 1, feeder hopper 2 is established at 1 top of outer frame, and the screen cloth is established to 1 inside of outer frame, the screen cloth includes three groups, down is with this from the top: the top layer large-hole net, the middle layer hollow net and the bottom layer small-hole net, and the three groups of screens and the bearing plate divide the interior of the outer frame into five areas. From top to bottom, the dust material area, the first particle area, the second particle area, the third particle area and the tailing area are taken as the same. The dust collection area is provided with a dust collection pipe, and the first particle area, the second particle area, the third particle area and the tailing area are respectively and correspondingly provided with a first collection pipe, a second collection pipe, a third collection pipe and a fourth collection pipe. Specifically, be the dirt material region above the loading board, establish the dust absorption pipe in the dirt material region, the dust absorption pipe establishes the dust collection box, and is preferred, avoids pellet feed to be inhaled the dust absorption pipe, establishes the separation net in the entrance of dust absorption pipe in order to guarantee that only material dirt is inhaled and is collected. A first particle area is arranged between the bearing plate and the top layer macroporous net, the mesh of the top layer macroporous net is the largest, the first particle area collects the feed with the largest particles, and a first collecting pipe is arranged in the first particle area. And a second particle area is arranged between the top layer macroporous net and the middle layer mesoporous net, a second collecting pipe is arranged in the second particle area, the meshes of the middle layer hollow net are smaller than those of the top layer macroporous net, and the particle size collected in the second particle area is between the mesh size of the middle layer mesoporous net and that of the top layer macroporous net. And a third particle area is arranged between the top layer middle mesh and the bottom layer small mesh, the meshes of the bottom layer small mesh are smaller than those of the middle layer middle mesh, a third collecting pipe is arranged in the third particle area, and the particle size collected in the third particle area is between the mesh size of the bottom layer small mesh and that of the middle layer middle mesh. The bottom layer small hole net bottom is a tailing area, a fourth collecting pipe is arranged in the tailing area, and the tailing area collects the smallest granular feed. Preferably, the first collecting pipe, the second collecting pipe, the third collecting pipe, the fourth collecting pipe and the dust collecting pipe are respectively provided with an air pump and a collecting box, air negative pressure is generated in the pipes during operation, and the feed in corresponding areas is collected and stored.

Establish vibrations machine case 13 in the bottom of outer frame 1, establish vibrating motor in the vibrations machine case 13, vibrating motor is connected with the screen cloth transmission, and is specific, three group's screens are fixed on same vibrations stick 18, vibrations stick 18 passes outer frame 1 and inserts in vibrations machine case 13, the vibrating motor transmission in vibrations machine case 13 is connected vibrations stick 18, and is preferred, adopts the commonly used vibrating motor on the market, connects the output at vibrating motor with vibrations stick 18 transmission. The bearing plate 3 of fretwork is established at the screen cloth top, a sweeping brush 5 is established through telescopic link 4 to bearing plate 3, sweeping brush 5 cross-section becomes triangle-shaped, establish brush head 501 on sweeping brush 5, the bearing plate 3 sets to the fretwork, and sweeping brush 5's cross-section is sharp-pointed wide triangle-shaped down, the whereabouts of the fodder of being convenient for. The gyro wheel 17 is established at the screen cloth both ends, and frame 1 and screen cloth junction establish spout 16, gyro wheel 17 is established in spout 16, and when the screen cloth vibrations, gyro wheel 17 rolls from top to bottom in spout 16, provides the vibrations space allowance of screen cloth on the one hand, and on the other hand reduces the friction between screen cloth and the outer frame. Establish elastic rubber skin 15 between screen cloth and the outer frame 1, elastic rubber skin 15 is the cyclic annular distribution in the junction of screen cloth and outer frame, guarantees the sealed of screen cloth corner, also guarantees that the screen cloth has certain vibrations space.

The specific working principle is as follows: pour into the fodder from feeder hopper 2, the fodder whereabouts gets into outer frame, vibrating motor work, the screen cloth begins to shake, colleague scavenging brush 5 also sets up the motor that corresponds, the scavenging brush falls to suitable position earlier, make the brush head can sweep the fodder that the big hole of top layer was netted, scavenging brush 5 rotates work, the screen cloth shakes, the granule is less than the whole whereabouts of fodder of the mesh of top layer big hole net, if there is partial large granule fodder or caking fodder stifled in the mesh, the scavenging brush sweeps, break up the caking fodder, sweep the large granule fodder of bottom, it chats the whereabouts to vacate the mesh to be convenient for the upper small granule private of mesh. The large granular feed which cannot fall down is finally left. The feed enters the second particle area, falls down again through the vibration of the screen mesh, leaves particles which cannot pass through the middle-layer middle-hole mesh, and so on, and finally leaves fine feed particles to fall on the tailing area. The dust and the materials which are lifted in the whole vibration process float upwards, the dust absorption pipe 6 absorbs the dust, and the feeds in other areas are collected and stored by the collecting pipes corresponding to the areas.

The above description is only for the preferred embodiment of the present invention, and the shown orientation or positional relationship is only for the convenience of describing the present invention and simplifying the description, the terms "disposed", "installed", "connected", "fixed", etc. should be understood in a broad sense, and various modifications and changes may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
