Description

Technical Field

[0001] This utility model belongs to the field of concrete preparation technology, and in particular to a concrete mixing mechanism and its mixing blades. Background Technology

[0002] Existing horizontal concrete mixing plants, such as Figure 1 , Figure 2 and Figure 3 As shown, the system includes a cylindrical body 1, inside which a mixing shaft 2 is installed. The mixing shaft 2 is connected to a mixing motor 4, and multiple mixing blades 3 are installed on the mixing shaft 2. The mixing blades 3 are typically rectangular. When the mixing blades 3 rotate with the mixing shaft 2 in the direction of arrow s, they drive the concrete to move, tumble, and mix. Some of the concrete moves along the length of the mixing blades 3 towards both ends, such as... Figure 3 As indicated by the middle arrow a, it then flows to the middle of cylinder 1, as shown. Figure 3 As indicated by the middle arrow b. Some of the concrete rolled over, as... Figure 2 As shown by arrow c, the concrete moving along arrow c mainly tumbles, and some concrete will not move to both ends of the mixing plate 3, and may always remain in the middle area of ​​the cylinder 1, thus failing to achieve the circulation flow from the middle to both ends and back to the middle. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a concrete mixing mechanism and its mixing blades, which can promote more concrete to circulate between the middle and both ends of the cylinder, thereby improving the mixing effect.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a stirring blade, including a blade body, the blade body having an mounting edge for mounting the blade body, and a baffle plate being provided at the mounting edge.

[0005] Furthermore, the baffle plate is perpendicular to the blade body.

[0006] Furthermore, the blade body has a scraping edge, which is one of the two sides of the blade body corresponding to the mounting edge. The mounting edge is a straight edge, and the distance from the scraping edge to the mounting edge decreases from the middle to both ends.

[0007] A concrete mixing mechanism includes a cylinder, a mixing shaft is installed inside the cylinder, a mixing motor is connected to the mixing shaft, and multiple mixing blades are installed on the mixing shaft.

[0008] Furthermore, the inner diameter of the cylinder decreases from the middle to both ends, the blade body has a scraping edge, the scraping edge and the mounting edge are two sides of the blade body corresponding to each other, the mounting edge is a straight edge, the distance from the scraping edge to the mounting edge decreases from the middle to both ends, and the scraping edge contacts the inner wall of the cylinder.

[0009] Furthermore, the cylinder is provided with a detachable installation and maintenance door.

[0010] Furthermore, a feed hopper is provided at the top of the cylinder, and an openable and closable discharge gate is provided at the bottom.

[0011] Furthermore, the mounting edge is connected to an arc-shaped mounting plate, which is detachably connected to the stirring shaft.

[0012] The beneficial effects of this utility model are as follows: By adding a baffle plate near the stirring shaft of the stirring blade, when the stirring blade rotates upward, it pushes the material to move and roll towards both ends of the stirring blade. Since the baffle plate blocks the material from rolling in the direction of arrow c, the amount of material remaining in the middle of the stirring blade can be reduced, and more material can be encouraged to flow to both ends of the stirring blade (i.e., move along arrow a) and then return to the middle of the cylinder.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] The concrete mixing mechanism of this utility model, such as Figure 6 and Figure 7As shown, the system includes a cylinder 1, inside which a stirring shaft 2 is installed. The stirring shaft 2 is connected to a stirring motor 4, which drives the stirring shaft 2 to rotate, thereby mixing the concrete raw materials. Multiple stirring blades are installed on the stirring shaft 2.

[0023] stirring blades Figure 4 and Figure 5 As shown, the device includes a blade body 10, which has a mounting edge 11 for mounting the blade body 10. The mounting edge 11 is connected to a stirring shaft 2, which can drive the blade body 10 to rotate. A baffle plate 12 is provided at the mounting edge 11. A gap is provided between the two ends of the blade body 10 and the inner walls of the two ends of the cylinder 1.

[0024] When mixing concrete, the mixing motor 4 drives the mixing shaft 2 and the blade body 10 to rotate in the direction of arrow s. When the blade body 10 rotates upward, it pushes the material upward, and some of the material moves towards the two ends of the blade body 10 along arrow a, and then flows back to the middle of the cylinder 1 along arrow b. Some of the material will roll along arrow c. Since the baffle plate 12 is set, the baffle plate 12 can block some of the material from rolling, causing more material to move towards the two ends of the blade body 10 along arrow a, so that more material can reach the two ends of the cylinder 1 and then return to the middle of the cylinder 1. This promotes more material to circulate in the middle and two ends of the cylinder 1, improving the mixing effect.

[0025] In this utility model, the baffle plate 12 is perpendicular to the blade body 10, and the baffle plate 12 can be welded to the blade body 10 as a whole.

[0026] To facilitate the return of material from both ends of the cylinder 1 to the middle, the inner diameter of the cylinder 1 decreases from the middle to both ends. The blade body 10 has a scraping edge 13, which, along with the mounting edge 11, are two corresponding sides of the blade body 10. The mounting edge 11 is a straight edge, and the distance from the scraping edge 13 to the mounting edge 11 decreases from the middle to both ends. The scraping edge 13 contacts the inner wall of the cylinder 1. The shape of the scraping edge 13 is adapted to the shape of the inner wall of the cylinder 1. When the blade body 10 rotates, it can scrape off adhesive materials such as cement adhering to the inner wall of the cylinder 1. Because the cylinder 1 is shaped with a larger middle and smaller ends, after the cylinder 1 is installed horizontally, the inner wall of the cylinder 1 is inclined, allowing the material at both ends to automatically slide down the inner wall of the cylinder 1.

[0027] For the installation, maintenance, and replacement of the mixing blades, the cylinder 1 is equipped with a detachable installation and maintenance door 5. The installation and maintenance door 5 can be bolted to the cylinder 1. After removing the installation and maintenance door 5, an installation and maintenance opening is formed on the cylinder 1. The size of the installation and maintenance opening is such that the blade body 10 and the baffle plate 12 can enter and exit the installation and maintenance opening as a whole. When assembling this concrete mixing mechanism, first assemble the mixing shaft 2 into place, then place the blade body 10 and the baffle plate 12 into the cylinder 1 through the installation and maintenance opening, and install the blade body 10 onto the mixing shaft 2. Install each blade body 10 in sequence.

[0028] The top of the cylinder 1 is equipped with a feed hopper 6 for introducing aggregates, powders, and water for concrete preparation. The bottom is equipped with an openable and closable discharge gate 7 for discharging the mixed concrete. One end of the discharge gate 7 is hinged to the cylinder 1, and the other end is connected to a hydraulic cylinder. The hydraulic cylinder drives the discharge gate 7 to rotate, thus opening and closing it. A sealing layer can be provided around the edge of the discharge gate 7 to improve sealing and prevent leakage.

[0029] The mounting edge 11 is connected to an arc-shaped mounting plate 14, which is detachably connected to the stirring shaft 2. The inner wall of the mounting plate 14 is fitted to the stirring shaft 2, and the mounting plate 14 can be connected to the stirring shaft 2 by multiple screws.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
