Abstract
The utility model relates to the field of sample preparation equipment, in particular to a screening device. The screening device comprises a base, a screening frame, a screening rolling plate, a collecting hopper and a reciprocating drive mechanism. The screening frame which is hollow in the middle and provided with rotary shafts at two ends respectively is arranged on the base in a sliding mode. Two ends of the screening rolling plate are wound on the rotary shafts at two ends of the screening frame respectively, a retaining ring is disposed above the screening rolling plate and arranged on the upper portion of the screening frame, a plurality of screening areas are distributed on the screening rolling plate, and a plurality of screening holes of certain specifications are arranged in the screening areas. The reciprocating drive mechanism is connected with the screening frame, so that the screening frame can slide back and forth on the base; and the collecting hopper is arranged on the lower portion of the screening frame and opposite to the screening rolling plate. According to the screening device, continuous screening areas with the screening holes of different specifications are arranged on the screening rolling plate, so that various screening requirements can be met rapidly by rotating the screening rolling plate; and a screening machine is not needed to be disassembled, and accordingly, the operation efficiency is improved and the service life of the screening machine is increased while the labor is saved.
Description
Technical field
The utility model relates to a kind of screening plant.
Background technology
Each sieve aperture specification sieve of existing screening machine is successively set on screening machine inside according to differing heights, and the size of screening machine is restricted, makes the specification of its inner sieve that arranges also very limited.Sample being sieved when sampling, according to different screening requirements, often need screening machine is taken apart then to change to meet the sieve that screening requires, reduced the operating efficiency of screening machine when having increased operating personnel's burden.
Summary of the invention
The utility model purpose is to solve above-mentioned existing screening machine need to tear the technical problems that machine replacing sieve could satisfy different screening requirements open, provide a kind of and can adjust rapidly the screening plant that the sieve aperture specification requires to satisfy screening, specifically realized by following technical scheme.
a kind of screening plant, this screening plant comprises base, sieve frame, the screening roll bending, receive bucket and reciprocating drive mechanism, the described frame that sieves is slidably disposed on base, this is that empty its two ends are respectively equipped with a rotating shaft in the middle part of sieving frame, described screening roll bending two ends are wound on respectively in the rotating shaft that sieves the frame two ends, the described frame top of sieving is provided with the back-up ring that is positioned at screening roll bending top, be distributed with several screen area on described screening roll bending, be provided with a plurality of sieve apertures of certain specification in described screen area, described reciprocating drive mechanism is connected with the described frame that sieves, make and sieve frame and reciprocatingly slide on base, described reception bucket is arranged on and sieves frame bottom and relative with described screening roll bending.
Described screening plant, its further design be, described reciprocating drive mechanism comprises eccentric wheel, motor and connecting rod, described motor is connected with eccentric center of rotation, described connecting rod two ends respectively with sieve frame and eccentric wheel is hinged.
Described screening plant, it further designs and is, and a described rotating shaft also is connected with a retracting motor, connects by a sprocket wheel link chain mechanism between two rotating shafts.
Described screening plant, its further design be, described base is provided with slide rail, the described frame bottom of sieving is provided with some rollers, described roller is connected with described slide rail rolling.
The utility model arranges the continuous screen area with the different size sieve aperture on the screening roll bending, divide roll bending can satisfy rapidly various screening operation requirements by trundle screen, need not screening machine is carried out dismounting, improved the service life of operating efficiency and screening machine when having saved manpower.

Fig. 2 is the structural representation of screening roll bending.
The specific embodiment
Below in conjunction with Figure of description and specific embodiment, the utility model is further illustrated.
this screening plant comprises base 1, sieve frame 2, screening roll bending 3, receive bucket 4 and reciprocating drive mechanism 5, sieving frame 2 is slidably disposed on base, this sieves frame 2 middle parts and is respectively equipped with a rotating shaft 21 for empty its two ends, screening roll bending 3 two ends are wound on respectively in the rotating shaft 21 that sieves the frame two ends, sieve frame 2 tops and be provided with the back-up ring 22 that is positioned at screening roll bending top, be distributed with several screen area 31 on screening roll bending 3, be provided with a plurality of sieve apertures 311 of certain specification in screen area 31, reciprocating drive mechanism 5 with sieve frame 2 and be connected, make and sieve frame 2 and reciprocatingly slide on base 1, reception bucket 4 is arranged on and sieves frame 2 bottoms and relative with the screen area on the screening roll bending.
Reciprocating drive mechanism 5 comprises eccentric wheel 51, motor 52 and connecting rod 53, and motor 52 is connected with the center of rotation of eccentric wheel 51, connecting rod 53 two ends respectively with sieve frame 2 and eccentric wheel 51 is hinged.One rotating shaft 21 also is connected by a pair of driving cog 6 with a retracting motor (not shown in FIG.), connects by a sprocket wheel link chain mechanism 7 between two rotating shafts.Base 1 is provided with slide rail 11, sieves frame 2 bottoms and is provided with some rollers 23, and roller 23 rolls with slide rail 11 and is connected.
During operation, rotate by retracting motor (not shown in FIG.), driving two rotating shafts 21 by sprocket wheel link chain mechanism 7 rotates, according to current screening requirement, make suitable screen area be positioned at back-up ring, drive by eccentric wheel 51 and sieve frame and moves back and forth on base and carry out screening operation, the received bucket reception of the sample that needs in screening operation.
The utility model arranges the continuous screen area with the different size sieve aperture on the screening roll bending, divide roll bending can satisfy rapidly various screening operation requirements by trundle screen, need not screening machine is carried out dismounting, improved the service life of operating efficiency and screening machine when having saved manpower.
