Abstract
The invention relates to the field of sample preparation equipment, in particular to a screening device, which comprises a base, a screening frame, a screening coil plate, a receiving hopper and a reciprocating drive mechanism, wherein the screening frame is arranged on the base in a sliding manner; the middle of the screening frame is hollow; two rotary shafts are respectively arranged at two ends of the screening frame; two ends of the screening coil plate are respectively wound around the rotary shafts at two ends of the screening frame; a check ring, positioned above the screening coil plate, is arranged at the upper part of the screening frame; a plurality of screening areas are distributed on the screening coil plate; a plurality of screen holes with certain specifications are formed in each screening area; the reciprocating drive mechanism is connected with the screening frame, and enables the screening frame to slide on the base in a reciprocating manner; and the receiving hopper is arranged at the lower part of the screening frame, and is opposite to the screening coil plate. According to the invention, the consecutive screening areas with different specifications of screen holes are arranged on the screening coil plate, various screening operation requirements can be met quickly through rotation of the screening coil plate, without the need of disassembling the screening device, and the operation efficiency and the service life of the screening device are improved and prolonged respectively while manpower is saved.
Description
Technical field
The present invention 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, so that the specification of its inner sieve that arranges is also very limited.Sample being sieved when sampling, according to different screening requirements, often need screening machine 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 object of the invention is to solve above-mentioned existing screening machine need to tear the technical problems that machine replacing sieve could satisfy different screening requirements open, provides a kind of sieve aperture specification of adjusting rapidly to sieve the screening plant that requires to satisfy, and is 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 the base, this sieves the frame middle part and is respectively equipped with a rotating shaft for empty its two ends, described screening roll bending two ends are wound on respectively in the rotating shaft that sieves the frame two ends, the described frame top that sieves is provided with the back-up ring that is positioned at screening roll bending top, be distributed with several screen area on the described screening roll bending, be provided with a plurality of sieve apertures of certain specification in the described screen area, described reciprocating drive mechanism is connected with the described frame that sieves, reciprocatingly slide at base so that sieve frame, described reception bucket is arranged on and sieves frame bottom and relative with described screening roll bending.
Described screening plant, its further design be that 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 that 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, it further designs and is that described base is provided with slide rail, and the described frame bottom that sieves is provided with some rollers, and described roller rolls with described slide rail and is connected.
The present invention arranges the continuous screen area with the different size sieve aperture at 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.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of screening roll bending.
The specific embodiment
Below in conjunction with Figure of description and specific embodiment the present invention is further specified.
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 the 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 the screening roll bending 3, be provided with a plurality of sieve apertures 311 of certain specification in the screen area 31, reciprocating drive mechanism 5 with sieve frame 2 and be connected, reciprocatingly slide at base 1 so that sieve frame 2, 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, so that suitable screen area is positioned at back-up ring, sieve frame by eccentric wheel 51 drives and carry out screening operation in the base reciprocating motion, the received bucket of the sample that needs in the screening operation receives.
The present invention arranges the continuous screen area with the different size sieve aperture at 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.
