Problems solved by technology

[0002] The sieves of each mesh size of the existing sieving machine are sequentially arranged inside the sieving machine according to different heights, and the size of the sieving machine is limited, so that the specifications of the sieves installed inside are also very limited.
When sieving and sampling samples, according to different sieving requirements, it is often necessary to disassemble the sieving machine and replace the sieve that meets the sieving requirements, which increases the burden on the operator and reduces the operating efficiency of the sieving machine

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] The screening device includes a base 1, a screening frame 2, a screening coil 3, a receiving bucket 4 and a reciprocating drive mechanism 5. The screening frame 2 is slidably arranged on the base, and the middle part of the screening frame 2 is empty. There is a rotating shaft 21 at each end, and the two ends of the screening coil 3 are respectively wound on the rotating shafts 21 at both ends of the screen moving frame. There are several sieving areas 31 distributed on the top, and a plurality of sieve holes 311 of a certain specification are arranged in the sieving area 31. The reciprocating drive mechanism 5 is connected with the sieve moving frame 2, so that the sieve moving frame 2 slides reciprocally on the base 1, receiving The bucket 4 is arranged on the lower part of the sieving frame 2 and is opposite to the screening area on t...

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 and a reciprocating drive mechanism, wherein the screening frame is arranged on the base in a sliding manner; 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 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; and the reciprocating drive mechanism is connected with the screening frame, and enables the screening frame to slide on the base in a reciprocating manner. 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 [0001] The invention relates to a screening device. Background technique [0002] The sieves of the sieve sizes of the existing sieving machines are sequentially arranged inside the sieving machine according to different heights, and the size of the sieving machine is limited, so that the specifications of the sieves installed inside are also very limited. When sieving and sampling samples, according to different sieving requirements, it is often necessary to disassemble the sieving machine and replace the sieve that meets the sieving requirements, which increases the burden on the operator and reduces the operating efficiency of the sieving machine. Contents of the invention [0003] The purpose of the present invention is to solve the technical problem that the above-mentioned existing screening machine needs to be dismantled and replaced to meet different screening requirements, and provides a screening device that can quickly adjust the size of the scre...
