Description

Mixer unloader that construction was used

Technical Field

The invention relates to a stirrer blanking device for building construction.

Background

Forced mixers have been rapidly developed and popularized since the beginning of the 20 th century and the 50 th era. The first appeared to be forced concrete mixers of the disc vertical shaft type. Such a stirrer is classified into a propeller type and a planetary type. After the 70 s in the 19 th century, with the application of lightweight aggregate, a circular groove horizontal shaft type forced stirrer appeared, which is divided into a single horizontal shaft type and a double horizontal shaft type and has the characteristics of self-falling and forced stirring. The linear velocity of the stirring blade is small, the wear resistance is good, the energy consumption is low, and the development is fast. The stirring blade is arranged on a rotating shaft arm support in the forced concrete mixer stirring cylinder, the materials in the stirring cylinder are added, and crossed logistics are formed under the strong stirring of the stirring blade. The stirring mode has stronger action than the self-falling stirring mode and is mainly suitable for stirring the dry and hard concrete.

However, when the forced mixer is used, workers directly put the materials piled on the ground into the concrete, massive objects such as stones and the like are often mixed into the materials, and when the wall surface is painted or the ground is poured at the later stage, the objects need to be additionally cleaned, so that the forced mixer is troublesome to operate, especially has requirements on the particle size of the concrete, and needs to screen out coarse-grained sand and the like, and the difficulty of manual operation is high. And the efficiency of the operation mode is lower by adopting a screening machine to screen and then carry out blanking.

Therefore, the mixer discharging device for building construction is designed, can be assembled at the top of a mixer, and can sieve raw materials while discharging.

Disclosure of Invention

The invention aims to provide a discharging device of a stirring machine for building construction, which can be assembled at the top of the stirring machine and can sieve raw materials while discharging.

In order to solve the problems, the invention adopts the following technical scheme:

a stirrer discharging device for building construction comprises a container arranged above a stirrer, wherein the diameter of the container is not smaller than that of the stirrer, a shaft center block is arranged at the bottom shaft center of the container, a plurality of connecting rods are welded between the shaft center block and the container, a fan-shaped area is formed between every two adjacent connecting rods, and a metal screen is welded in the formed fan-shaped area; a supporting structure is arranged on the side wall of the stirrer, and a quick-release structure is matched between the supporting structure and the container; and a scraping device is arranged at the position of a stirring shaft of the stirring machine, the scraping device rotates along with the rotation of the stirring shaft, and the scraping device acts on the metal screen.

Preferably, the top of the connecting rod is processed into an inverted V-shaped shape, a through hole vertically penetrates through the top of the connecting rod, a partition plate is assembled above the connecting rod, an inverted V-shaped groove corresponding to the connecting rod is formed in the bottom of the partition plate, an insertion shaft inserted into the through hole is welded at the bottom of the partition plate, and the mesh sizes of two adjacent metal screens are different. A blanking gap is formed between every two adjacent partition boards, when blanking is conducted, blanking is conducted through the edge of the container, the end, far away from the inner wall of the container, of each partition board is disconnected, and therefore when blanking is insufficient or the metal screen is blocked and blanking cannot be conducted timely, excessive raw materials can leak from the gap between the tail ends of the adjacent partition boards, and emergency blanking of the metal screen at other places is conducted. In a normal state, blanking is carried out from the edge of the container, and a scraping device is matched, so that the screening is finished when the blanking raw materials do not reach the breaking part of the adjacent partition plate; the connecting rod is inverted V-shaped, so that the raw materials are prevented from staying on the surface of the connecting rod under the condition of not using a partition plate.
