Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a high-efficiency feed primary screening device. Background Art

[0002] The feed vibrating screen uses motor excitation as the vibration source to throw the material on the screen and move forward in a straight line. The material enters the feed port of the screening machine evenly from the feeder, and passes through the screen to produce oversize and undersize materials of different specifications, which are discharged from different ports respectively.

[0003] After the existing feed screening device completes the feed screening, the feed and debris discharged from the discharge port are directly discharged onto the ground, which causes a lot of inconvenience to the subsequent processing and collection, and consumes a lot of time to clean up. For this reason, we propose an efficient feed primary screening device. Utility Model Content

[0026] In this embodiment, the first collecting mechanism 2 includes a first box body 201 , and two groups of guide rods 207 are fixedly connected to the bottom end inside the first box body 201 . The outer sides of the two groups of guide rods 207 are slidably connected to a baffle 206 , and the inner side of the baffle 206 is fixedly connected to a sleeve 205 .

[0027] Specifically, the screened feed falls into the first box body 201 , and the baffle plate 206 is driven to rise and fall on the guide rod 207 through the sleeve 205 .

[0028] In this embodiment, a first motor 210 is installed at the lower end of the first box body 201, and the output shaft of the first motor 210 is fixedly connected with a coupling 209. The coupling 209 is fixedly connected with a threaded rod 204. The threaded rod 204 is threadedly connected to a sleeve 205. The upper end of the threaded rod 204 is fixedly connected with a rotating shaft 202, and four groups of sweeping rods 203 are fixedly installed on the outer side of the rotating shaft 202.

[0029] Specifically, the first motor 210 drives the threaded rod 204 to rotate through the coupling 209. The sleeve 205 performs a lifting motion during the rotation of the threaded rod 204. The rotating shaft 202 connected to the top of the threaded rod 204 rotates along with the rotation of the threaded rod, driving the sweeping rod 203 to rotate.

[0030] In this embodiment, a discharge hopper 208 is fixedly connected to the front end of the first box body 201 .

[0031] Specifically, the feed in the first box body 201 can be discharged from the discharge hopper 208 .

[0032] In this embodiment, the second collecting mechanism 3 includes a second box body 301, and two groups of crushers 302 are rotatably connected inside the second box body 301. The front ends of the two groups of crushers 302 are fixedly connected with two groups of gears 303, and one of the two groups of gears 303 is connected to the output shaft of the second motor 304.

[0035] Specifically, the crushed debris flows from the filter 305 into the collection box 306 .

[0036] Working principle: When the screening mechanism 1 completes the screening, the feed falls from the discharge port into the first collecting mechanism 2, the first motor 210 is started to drive the threaded rod 204 to rotate, drive the sleeve 205 to rise, and the baffle 206 fixedly connected to the sleeve 205 also rises to the upper end of the discharge port, thereby achieving the purpose of temporarily storing the feed. When it is necessary to collect the feed, the first motor 210 is rotated in the opposite direction to drive the baffle 206 to drop to the bottom of the discharge port. At the same time, the rotating shaft 202 connected to the threaded rod 204 will also rotate, thereby driving the four sets of sweeping rods 203 to rotate, applying a flow force to the feed stored in the first box body 201, so that the feed is discharged from the two outlets, and the sundries discharged from the sundries outlet fall into the second collecting mechanism 3, and after being crushed by the crusher 302, they fall into the collection box 306 through the filter 305, which is more convenient for collection and dumping.
