Mobile aggregate screening device

Abstract

The invention discloses a mobile aggregate screening device. The mobile aggregate screening device comprises an underframe, as well as a storage mechanism and a screening mechanism which are arranged on the underframe; traveling wheels and an automatic charging mechanism are arranged on the underframe; the screening mechanism comprises a screening cabin; screening cabin supports are arranged on two sides of the underframe; a vibrating spring is connected to the upper end of each screening cabin support; the screening cabin is fixedly connected to the tops of the screening cabin supports through the vibrating springs; multiple stages of sieve plates are obliquely connected into the screening cabin in a layered manner; a discharge funnel is arranged below each stage of sieve plate; the storage mechanism comprises a plurality of storage cabins which are arranged below the discharging funnels and are provided with discharging holes; feeding holes in the upper parts of the storage cabins respectively correspond to all stages of discharging funnels; the automatic charging mechanism comprises a feeding cabin arranged at the front end of the underframe and a conveying belt which extends from the interior of the feeding cabin to a position above the screening cabin and is driven by a drive motor to work; conveying grooves are uniformly distributed in the outer surface of the conveying belt. The mobile aggregate screening device is simple in structure, time-saving and labor-saving to operate, much more in grading quantity, high in working efficiency and convenient for analysis research.

Description

technical field [0001] The invention relates to aggregate screening, in particular to a mobile aggregate screening device. Background technique [0002] At present, aggregate screening machines are widely used in many fields such as construction (including water conservancy and hydropower, roads and bridges, civil houses), refractory materials, machinery, and chemical industry. Most of the screening machines used are large in size and extremely heavy, which is inconvenient The number of moving and grading aggregates is small, and the screening accuracy is low, which is completely unsuitable for the high-precision aggregate screening required for indoor research and analysis. Of course, there are also some indoor screening machines dedicated to laboratories, but due to their small size, the screening efficiency is far from meeting the requirements of use, and there is also the problem of low aggregate screening numbers.

[0002] At present, aggregate screening machines are widely used in many fields such as construction (including water conservancy and hydropower, roads and bridges, civil houses), refractory materials, machinery, and chemical industry. Most of the screening machines used are large in size and extremely heavy, which is inconvenient The number of mobile and aggregate grading is small, and the screening accuracy is low. It is completely unsuitable for the high-precision aggregate screening required for indoor research and analysis.

Of course, there are also some special indoor screening machines for laboratories, but due to the small size, the screening efficiency is far from meeting the requirements of use, and there is also the problem of low aggregate screening number.
