Description

Technical Field

[0001] The utility model relates to the technical field of mixing production devices, and particularly relates to a concrete mixing production device. Background Technique

[0002] Concrete refers to the general term for engineering composite materials that are cemented into a whole by cementitious materials. Usually, the term concrete refers to cement concrete obtained by mixing cement, sand, stones and water in a certain proportion and stirring. Concrete is widely used in civil engineering. When producing concrete, a mixing production device is used to mix various raw materials;

[0003] CN202221872942.5 discloses a concrete mixing device, which includes a mixing barrel, a reciprocating motion component and a mixing component. Among them, the mixing component includes a fixed end, a motor, a rotating shaft, a bearing and a mixing rod. Horizontal scraping blades and vertical scraping blades are arranged at the end of the mixing rod and can both contact the inner wall of the mixing barrel. Since the motor is fixed on the sliding part and the mixing rod is arranged on the rotating shaft located inside the mixing barrel, through the arrangement of the horizontal scraping blades and the vertical scraping blades, when the air cylinder and the motor work, the inner wall of the mixing barrel can be cleaned in time, avoiding the phenomenon that concrete residues adhere to the inner wall of the mixing barrel after long-term use and are difficult to clean;

[0004] When the concrete mixing device cleans the inner wall of the mixing barrel through the horizontal scraping blades and the vertical scraping blades, the scraping blades rub against the concrete on the inner wall of the mixing barrel. Once the end of the scraping blade is worn, it cannot contact the inner wall of the mixing barrel. When the scraping blade cannot fit the inner wall of the mixing barrel, the concrete on the inner wall cannot be cleaned, and it is difficult to achieve the effect of cleaning the inner wall of the mixing barrel. For this reason, a concrete mixing production device is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a concrete mixing production device to solve the problems raised in the above background technique.

Stirring blades are welded on the outer side wall of the rotating shaft. An installation frame is welded on the outer side wall of the rotating shaft near one end of the tank cover. Two rotating rods are symmetrically welded on the lower surface of the installation frame. Installation grooves are evenly arranged on one side of the rotating rod close to the inner side wall of the tank body. The installation grooves are fixedly connected to the rotating rods through the bolts. The inner surface of the installation groove is slidably connected with an installation plate. A spring in a compressed state is fixedly connected between the installation groove and the installation plate. A scraping plate is fixedly connected to one side of the installation plate close to the inner side wall of the tank body.

[0025] Please refer to Figure 1-7, the present utility model provides a technical solution: a concrete mixing production device, including a tank body 1, a motor 2, a rotating shaft 3 and bolts 4, characterized in that: a tank cover 5 is installed on the upper surface of the tank body 1, a feeding groove 6 is communicated with the rear side of the upper surface of the tank cover 5, the motor 2 is installed in the middle of the upper surface of the tank cover 5, the rotating shaft 3 penetrates the tank cover 5 and is fixedly connected with the output shaft end of the motor 2, a stirring blade 7 is welded on the outer side wall of the rotating shaft 3, an installation frame 8 is welded on the outer side wall of the rotating shaft 3 near one end of the tank cover 5, two rotating rods 9 are symmetrically welded on the lower surface of the installation frame 8, a plurality of installation grooves 10 are uniformly arranged on the side of the rotating rod 9 close to the inner side wall of the tank body 1, the installation grooves 10 are fixedly connected with the rotating rods 9 through the bolts 4, an installation plate 11 is slidably connected to the inner surface of the installation grooves 10, a spring 12 in a compressed state is fixedly connected between the installation grooves 10 and the installation plate 11, and a scraping plate 13 is fixedly connected to the side of the installation plate 11 close to the inner side wall of the tank body 1; Pour the material to be stirred into the tank body 1 along the feeding groove 6, start the motor 2 to drive the rotating shaft 3 to rotate, the stirring blade 7 stirs the material inside the tank body 1, and at the same time the installation frame 8 drives the rotating rod 9 to rotate. When the installation groove 10 and the installation plate 11 rotate, the scraping plate 13 cleans the concrete on the inner surface of the tank body 1, thus constituting a concrete mixing production device. When the end of the scraping plate 13 is worn due to friction, under the action of the spring 12, the installation plate 11 moves in a direction away from the installation groove 10, and the scraping plate 13 can thus maintain a state of being closely attached to the inner side wall of the tank body 1. When the scraping plate 13 is worn to the extent that it cannot be closely attached to the inner side wall of the tank body 1, open the tank cover 5 and turn the bolts 4 to disconnect the installation groove 10 from the rotating rod 9, and the components such as the installation plate 11 and the scraping plate 13 can be replaced.

[0026] In this embodiment, specifically: a discharge pipe 14 is communicated with the lower surface of the tank body 1; it is convenient to discharge the mixed material from the tank body 1.

[0027] In this embodiment, specifically: a chute 15 is opened on the lower surface of the tank body 1, a slider 16 is slidably connected to the inner side wall of the chute 15, a baffle 17 is welded on the upper surface of the slider 16, and a connecting block 18 is welded on the lower surface of the slider 16; it is convenient to control the opening and closing state of the discharge pipe 14 through the baffle 17.

[0028] In this embodiment, specifically: an electric cylinder 19 is arranged at the left end of the discharge pipe 14, and one end of the piston rod of the electric cylinder 19 is fixedly connected to the left side wall of the connecting block 18; it is convenient to electrically control the opening and closing state of the discharge pipe 14.

[0029] In this embodiment, specifically: the lower surface of the electric cylinder 19 is fixedly connected with a bracket 20, and a positioning plate 21 is welded on the left side of the upper surface of the bracket 20; it plays a role in supporting the electric cylinder 19.

[0030] In this embodiment, specifically: a control panel 22 is installed on the right side of the outer surface of the tank body 1, and the electrical output terminals of the control panel 22 are electrically connected to the electrical input terminals of the motor 2 and the electric cylinder 19 through wires respectively; it can be used to control the working states of the motor 2 and the electric cylinder 19.

[0031] In this embodiment, specifically: the lower surface of the tank body 1 is uniformly welded with supporting legs 23; which play a role in supporting the tank body 1.

[0032] In this embodiment, specifically: a cover plate 24 is hinged to the rear side of the upper surface of the feed chute 6, and a handle 25 is welded to the upper surface of the cover plate 24; when the present utility model is in a non-working state, the feed chute 6 can be closed through the cover plate 24.

[0033] The working principle of the present utility model is as follows: Pour the material to be stirred into the tank body 1 along the feed chute 6, start the motor 2 to drive the rotating shaft 3 to rotate, and the stirring blades 7 perform a stirring operation on the material inside the tank body 1. At the same time, the mounting frame 8 drives the rotating rod 9 to rotate as well. When the mounting groove 10 and the mounting plate 11 rotate, the scraping plate 13 cleans the concrete on the inner surface of the tank body 1. When the end of the scraping plate 13 is subject to frictional wear, the spring 12 returns from the compressed state, and under the action of the elastic force, the mounting plate 11 displaces in a direction away from the mounting groove 10, thereby compensating for the wear of the scraping plate 13. Thus, the scraping plate 13 can maintain a state of being closely attached to the inner side wall of the tank body 1. When the scraping plate 13 is worn to the point where it cannot be closely attached to the inner side wall of the tank body 1, open the tank cover 5 and turn the bolt 4 to disengage the mounting groove 10 from the rotating rod 9, and components such as the mounting plate 11 and the scraping plate 13 can be replaced.

[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
