Description

Technical Field

[0001] This utility model relates to the field of commercial concrete technology, specifically to a commercial concrete mixing plant with a feed inlet protection structure. Background Technology

[0002] A concrete mixing plant is a building material manufacturing equipment that typically consists of five major systems: a concrete mixing host, a material weighing system, a material conveying system, a material storage system, and a control system, as well as other auxiliary facilities. Its main working principle is to use cement as a binder to mix and stir raw materials such as sand, gravel, lime, and cinders, and finally produce concrete.

[0003] Chinese patent provides a concrete mixing host for a commercial concrete mixing plant, publication number CN218462560U, which includes a mixing host body and a propeller. The propeller is located inside the mixing host body, and a mounting frame is provided inside the mixing host body. A drive motor is fixedly installed on one side of the mounting frame. One end of the propeller is connected to the output end of the drive motor, and the other end of the propeller is rotatably connected to the mounting frame through a bearing.

[0004] The aforementioned mixing plant is equipped with a servo motor, lead screw, adjusting cylinder, and connecting frame. The output of the drive motor drives the propeller to rotate, which is used to mix concrete. To improve the mixing effect, the output of the servo motor drives the lead screw to rotate, causing the adjusting cylinder to move up and down along the lead screw. This, in turn, causes the connecting frame to drive the propeller to move up and down, facilitating thorough mixing of the concrete inside the mixing unit. The mixing effect is relatively good. However, if too much material is added during the feeding process, the raw material may clog the feed pipe, and if the material is fed too quickly, it may damage the mixing blades, affecting subsequent use. Utility Model Content

[0005] The purpose of this utility model is to provide a commercial concrete mixing plant with a feed inlet protection structure to solve the problems of raw materials clogging the feed pipe when too much material is fed during the feeding process, and damage to the mixing blades caused by feeding too quickly, which affects subsequent use.

A material leakage port is opened on the circular plate. A feed pipe is fixedly passed through the hollow plate. A connecting pipe is fixedly connected between the hollow plate and the cover plate. Two L-shaped plates are fixedly connected to the top of the cover plate. A dual-shaft motor is fixedly connected between the two L-shaped plates. A drive shaft is fixedly connected to one drive end of the dual-shaft motor and passes through the hollow plate and the circular plate. An elastic column is fixedly connected to the outer wall of the drive shaft.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combination Figures 1-4 A commercial concrete mixing plant with a feed inlet protection structure includes a mixing drum 1, a protection mechanism 2 at the top of the mixing drum 1, and a lifting mechanism 3 on the outer wall of the mixing drum 1.

[0024] See Figures 1-3 Furthermore, the protection mechanism 2 includes a cover plate 201 set at the top of the mixing tank 1. Support columns 202 are fixedly connected to the four corners of the top of the cover plate 201. Hollow plates 203 are fixedly connected to the top of the four support columns 202. A circular plate 204 is provided on the inner wall of the hollow plate 203. A material leakage port 205 is opened on the circular plate 204. A feed pipe 206 is fixedly passed through the hollow plate 203. A connecting pipe 207 is fixedly connected between the hollow plate 203 and the cover plate 201. Two L-shaped plates 208 are fixedly connected to the top of the cover plate 201. A dual-shaft motor 209 is fixedly connected between the two L-shaped plates 208. A drive shaft 210 is fixedly connected to one drive end of the dual-shaft motor 209 and passes through the hollow plate 203 and the circular plate 204. An elastic column 211 is fixedly connected to the outer wall of the drive shaft 210.

[0025] Specifically, the cover plate 201 covers the top of the mixing tank 1 to complete the closure operation. The support column 202 can limit and fix the hollow plate 203. The circular plate 204 can block and quantitatively discharge the falling concrete material to prevent excessive discharge and blockage. The dual-shaft motor 209 drives the drive shaft 210 to rotate, which in turn drives the circular plate 204 to rotate. At the same time, the drive shaft 210 drives the elastic column 211 to rotate, which can knock and beat the connecting pipe 207. The vibration generated by knocking is conducive to the falling of concrete material and further prevents blockage.

[0026] Example 2

[0027] See Figure 1 and Figure 2 Furthermore, based on Embodiment 1, the lifting mechanism 3 includes first fixing blocks 301 fixedly connected to both sides of the outer wall of the mixing tank 1. Hydraulic rods 302 are fixedly connected to the top of each of the two first fixing blocks 301. Second fixing blocks 303 are fixedly connected to the telescopic ends of each of the two hydraulic rods 302. Both second fixing blocks 303 are fixedly connected to the cover plate 201. An annular groove is provided at the top of the mixing tank 1. A ring that matches the shape of the annular groove is fixedly connected to the bottom of the cover plate 201.

[0028] Specifically, the hydraulic rod 302 is fixed by the first fixing block 301, and the two hydraulic rods 302 are controlled by a synchronous controller to achieve synchronous lifting and lowering. The cover plate 201 can be moved upward by the second fixing block 303, so that the inner wall of the mixing tank 1 can be cleaned, making it convenient to thoroughly clean the inner wall of the mixing tank 1.

[0029] Example 3

[0030] See Figure 2 and Figure 4 Furthermore, based on Embodiment 1 and Embodiment 2, it is further found that the other drive end of the dual-shaft motor 209 is fixedly connected to the stirring shaft 4 and passes through the cover plate 201. Multiple stirring blades 5 are fixedly connected to the outer wall of the stirring shaft 4. The bottom end of the stirring tank 1 is fixedly connected to the discharge pipe 6. The bottom end of the discharge pipe 6 is fixedly connected to the solenoid valve 7. Multiple circular holes for reducing resistance are opened on the multiple stirring blades 5. The multiple stirring blades 5 are vertically distributed.

[0031] Specifically, the dual-shaft motor 209 synchronously drives the mixing shaft 4 to rotate, which in turn drives the mixing blade 5 to rotate, thus mixing the concrete. The circular holes on the mixing blade 5 can reduce the resistance during mixing, thereby reducing the energy consumed by the dual-shaft motor 209. After mixing, the solenoid valve 7 is opened to allow the mixed concrete to flow out.

[0032] In actual operation, the dual-shaft motor 209 is first started to rotate the drive shaft 210, which in turn rotates the circular plate 204. When the material outlet 205 on the circular plate 204 is between the feed pipe 206 and the connecting pipe 207, the concrete raw material will fall into the mixing tank 1, so that it can be quantitatively added to prevent excessive addition and blockage. The drive shaft 210 rotates the elastic column 211. Since the elastic column 211 is elastic, it can knock and beat the connecting pipe 207 and generate vibration, which can further prevent blockage. Therefore, the feed pipe 206 can be protected.

[0033] After use, the hydraulic rod 302 is activated to move the second fixing block 303 upward, which in turn moves the cover plate 201 upward, thus exposing the internal structure of the mixing tank 1. This facilitates a thorough cleaning of the inside of the mixing tank 1, ensuring its cleanliness and preventing the concrete from hardening and affecting subsequent use.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
