Screening machine for dry-mixed mortar production

Abstract

The invention discloses a screening machine for dry-mixed mortar production. The screening machine comprises a machine shell, a discharging opening, a cover plate and a feeding hopper; the bottom endof the interior of the machine shell is fixedly connected with a supporting frame through a second spring seat; the upper side of the supporting frame is fixedly connected with a second screening netplate through a first electric push rod and a ball cup; a first screening net plate is fixedly connected to the upper side of the second screening net plate; a material guiding plate is inserted intothe side wall of the machine shell; the material guiding plate is movably connected with an L-shaped material guiding frame through a locking hand wheel; and a first material box is arranged at the bottom of the machine shell. One end of the second screening net plate is lifted through the first electric push rod, granular materials are automatically discharged along the material guiding plate, the granular materials in a second material box are weighed through an electronic scale, the waiting time is shortened through a tail gas treatment box, the working efficiency is improved, a hairbrush and a rubber strip effectively improve the sealing performance of the joint of the first material box and the discharging opening, flying of dust materials is reduced, and the comfort degree of the working environment is increased.

Description

technical field [0001] The invention relates to the related technical field of mechanical equipment, in particular to a screening machine for dry-mixed mortar production. Background technique [0002] Dry-mixed mortar refers to dry-screened aggregates and cement and various components determined according to performance, which are mixed in a professional production plant in a certain proportion, and mixed with water or supporting liquid in a specified proportion at the place of use. Dry mix. Dry mix mortar is also known as dry mix mortar. The naming methods are different, one is classified by storage status, and the other is classified by construction usage. Dry-mixed mortar generally means that all the materials of the mortar have been pre-mixed in a certain proportion in the factory, and only need to add water and stir on site, and then construct. Screening machine is an auxiliary mechanical equipment for sieving dry-mixed mortar. [0003] However, the existing screeni...

Problems solved by technology

[0007] The purpose of the present invention is to provide a screening machine for dry-mixed mortar production, so as to solve the problem in the above-mentioned background technology that it is not convenient to fill the materials remaining in different screens after using electric screens to filter the dry-mixed mortar. , dust adheres to the outer surface of the granular material, direct manual filling operation is troublesome, and the material cannot be weighed effectively during filling; during the process of sieving, the powdery material is sieved to the bottom position, In order to facilitate the filling process, a discharge port will be set at the bottom of the sub-sieve casing. When the dusty material is unloaded, it will be affected by the wind and float in the air, which will reduce the comfort of the working environment and is not conducive to human health; sub-sieving operation After the completion, there is a large amount of suspended solids inside the casing, and directly opening the cover will cause air pollution, which needs to be left for static treatment, and the waiting time is long, which affects the processing efficiency.
