Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, in particular to a concrete aggregate processing device. Background Art

[0002] Concrete aggregate refers to granular loose materials that play a role of skeleton or filling in concrete; as the main raw material in concrete, aggregate plays a role of skeleton and support in buildings, and aggregate can be divided into fine aggregate and coarse aggregate. The particle diameter of fine aggregate is between 0.16 mm and 5 mm, and natural sand is generally used, such as river sand, sea sand and valley sand, etc. When natural sand is lacking, artificial sand ground from hard rock can also be used. The particle diameter of coarse aggregate is greater than 5 mm. In lightweight aggregate concrete, the diameter of coarse aggregate is relatively large and not convenient for use, so it needs to be processed. Traditional concrete blocks are directly conveyed to the feed inlet of the crusher through a large conveyor belt. In order to reduce the transportation cost of convenient blocks in some large processing plants, a bent and inclined conveying method will be adopted, which makes these blocky concretes have a certain inertia when entering the feed inlet. When the falling speed of the concrete material is too fast, some materials collide with the crushing teeth and are squeezed out of the crushing cavity without being fully broken, forming larger blocks, while another part of the materials may be over-crushed to form too small particles, resulting in uneven particle size of concrete aggregate. In view of this, a concrete aggregate processing device is proposed. Content of the Utility Model

A roller shaft with adjustable position is arranged in the middle of the bottom shell. A second installation shell is arranged above the bottom shell. A first driving motor is arranged on one side of the second installation shell. The output end of the first driving motor is provided with a first conveyor belt. The first conveyor belt is connected to a crushing shaft. A third installation shell is arranged above the crushing shaft. A fourth installation shell is arranged above the third installation shell. Electric push rods are arranged on both sides of the fourth installation shell.

[0004] Further, shaft holes are arranged on both sides of the bottom shell. A displacement groove is arranged on one side of the shaft hole. The shaft hole and the displacement groove are respectively connected to two roller shafts. Moreover, symmetrically arranged slide bars are also arranged on the bottom shell, and a slide table is connected to the slide bars.

[0005] Further, an extension bar is arranged at the bottom of the slide table. A chute is arranged on the slide bar. The extension bar is connected to the slide bar. Moreover, a jack is arranged in the middle of the slide table. The jack is inserted into one of the roller shafts. An embedded hole is also arranged on one side of the jack, and a matching fixing rod is connected in the embedded hole.

[0006] Furthermore, external threads are provided outside the fixing rod. An extension plate is also provided on one side of the sliding strip. A connection hole for threaded connection with the fixing rod is provided in the middle of the extension plate. A circular limiting piece is also provided on one side of the fixing rod. A circular embedded groove is provided in the embedded hole, and the embedded groove is connected to the limiting piece. At the same time, the outer end of a roller shaft connected in the jack is also connected to a second transmission belt, and the other side of the second transmission belt is connected to a second driving motor.

[0007] Furthermore, the limiting piece and the embedded groove are of the same size, and there are two extension plates.

[0008] Furthermore, symmetrically installed side extension shells are also provided on both sides of the fourth installation shell. Installation grooves are provided at the diagonal corners of the extension shell, and the installation grooves are connected to the electric push rods.

[0009] Furthermore, the push plate and the connection groove are of the same size.

[0010] Furthermore, matching crushing hammers are provided on the crushing shaft.

[0011] Furthermore, a downwardly inclined blanking plate is also provided below the second installation shell.

[0012] Beneficial effects: When the concrete material enters the fourth installation shell, the electric push rod controls the distance between the two push plates according to the size of the concrete block to adjust the feeding speed, ensuring that the concrete blocks enter evenly below for crushing. After entering the crushing shaft, the first driving motor cooperates with the first transmission belt to use the crushing hammers outside the crushing shaft to uniformly crush the concrete blocks once. The crushed concrete material then enters between the two roller shafts through the downwardly inclined blanking plate for rolling. If it is necessary to adjust the particle size of the once-crushed concrete blocks, then rotate the fixing rod so that it meshes with the internal threads in the middle of the two extension plates for position change, and at the same time drive the sliding table to move in the displacement groove, so as to adjust the distance between the two roller shafts to achieve the effect of changing the crushing particle size of the concrete.
