DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] The present invention provides Figure 1-3 A continuous self-falling concrete mixing device is shown, comprising: A mixing mechanism 100 is used to mix various raw materials of concrete. In a preferred embodiment, the mixing mechanism 100 includes a mixing bin 101. The top of the mixing bin 101 is in the shape of a downwardly concave cavity. A stirring assembly is arranged in the mixing bin 101. A support frame 102 is fixedly connected to the bottom of the mixing bin 101. A discharge pipe 110 connected to the inside of the mixing bin 101 is fixedly connected to the bottom of the side wall of the mixing bin 101. A mixing motor 108 for driving the stirring assembly to rotate is fixedly connected to the bottom of the mixing bin 101. The mixing motor 108 is fixedly installed in the middle of the support frame 102. When the mixing motor 108 is powered on, it drives the stirring assembly to rotate in the mixing bin 101, so as to stir the raw materials in the mixing bin 101, so that the raw materials can be fully mixed and evenly mixed, thereby obtaining the desired concrete. The discharge pipe 110 can be detachably installed with an end cover or a switch valve for blocking, so as to control the automatic discharge of concrete. The material dropping mechanism 200 is arranged at one side of the mixing mechanism 100. The material dropping mechanism 200 includes an outer shell 201. The top of the outer shell 201 extends obliquely upward to the upper position of the mixing mechanism 100. A feeding auger 202 is rotatably connected in the outer shell 201. A storage bin 205 for conveying materials into the outer shell 201 is provided at the bottom of the outer shell 201. A material dropping pipe 206 is connected to the top of the outer shell 201. The bottom end of the material dropping pipe 206 faces the inner side of the mixing mechanism 100. The feeding in the outer shell 201 is driven by the auger motor 204. The auger 202 rotates, so that the material in the storage bin 205 can be continuously fed along the extension direction of the outer shell 201 by the rotation of the spiral blades on the feeding auger 202, so that the material is continuously dropped from the port of the drop pipe 206 above the mixing bin 101 into the cavity of the mixing bin 101, thereby realizing the continuous dropping of concrete raw materials, accompanied by the continuous stirring of the stirring component, so that the material can be stirred more evenly in the mixing bin 101, and at the same time, the stirring resistance of the stirring component is also reduced, which helps to achieve an energy-saving and efficient working mode and speed up the working efficiency of concrete mixing.
[0023] Among them, the material dropping mechanism 200 also includes a hopper seat 203, which is fixedly arranged at the bottom end of the storage bin 205, and the hopper seat 203 is used to support the outer shell 201 and the storage bin 205. Through the supporting effect of the hopper seat 203, the outer shell 201 and the material storage bin 205 can be stably placed; the bottom end of the outer shell 201 is fixedly connected with an auger motor 204 for driving the feeding auger 202 to rotate, and the side wall of the mixing mechanism 100 is provided with an auxiliary support seat 207, one side of the auxiliary support seat 207 is fixedly connected to the outer wall of the outer shell 201, and the setting of the auxiliary support seat 207 can increase the contact area between the outer shell 201 and the mixing bin 101, thereby improving the stability of the support for the outer shell 201.
[0024] In a preferred embodiment, the stirring assembly includes a rotating shaft 103, which is rotatably connected to the middle position of the inner side of the mixing bin 101, and the bottom end of the rotating shaft 103 extends to the bottom end of the mixing bin 101 and is transmission-connected to the rotating end of the mixing motor 108. A sealed bearing is installed between the rotating shaft 103 and the mixing bin 101, and the outer wall of the rotating shaft 103 is in a ring array and fixedly connected with a plurality of stirring blades 104 at intervals, and the side of the stirring blade 104 facing the rotation direction is conical. By setting the side of the stirring blade 104 facing the rotation direction to be conical, it is helpful to push away the concrete raw materials in the mixing bin 101, reduce the resistance of the stirring blade 104 during the rotation process, improve the stirring efficiency, and improve the stirring effect; In addition, one end of one set of stirring blades 104 away from the rotating shaft 103 is fixedly connected to a scraper plate 105, and the side of the scraper plate 105 away from the stirring blades 104 is in contact with the inner wall of the mixing bin 101, and a scraper bottom plate 106 is provided below the other set of stirring blades 104, and the bottom end of the scraper bottom plate 106 is in contact with the bottom inner wall of the mixing bin 101, and the top of the scraper bottom plate 106 is fixedly connected to a fixing rod 107, and the top end of the fixing rod 107 is fixed to the stirring blade 104 at the corresponding position, and the stirring blade 104 is fixed to the stirring blade 104. While rotating, the scraper plates 105 and the scraper bottom plates 106 are staggered so that the scraper plates 105 can scrape the inner wall of the mixing bin 101 to prevent the concrete raw materials from adhering to the side wall of the mixing bin 101 for a long time and being unable to detach, thereby easily solidifying and making subsequent cleaning more difficult, and also avoiding waste of raw materials. Similarly, the scraper plates 105 are used to scrape the materials adhered to the inner wall of the bottom side of the mixing bin 101 while the mixing blades 104 are rotating and stirring, thereby preventing the materials from sticking.
[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
