[0002] A sand mixing device is a device used to mix raw materials such as cement, aggregate, sand and water to make concrete. When constructing in the field or other construction sites, in order to improve construction efficiency, a mobile concrete mixing device with automatic loading is generally used. The automatic loading concrete mixing device automatically loads materials through a hopper, but because the hopper is filled with a shake of raw materials each time when shoveling materials, most of the hoppers in the prior art directly pour all the raw materials into the mixing tank when adding materials to the mixing tank.

DETAILED DESCRIPTION
[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.
[0025] Combine the following Figures 1 to 6 The invention describes an automatic speed regulating uniform stirring and sand mixing device.
[0026] In one embodiment, an automatic speed regulating uniform stirring and sand mixing device is provided, characterized in that it includes a mounting frame 100 and a stirring tank 200; the stirring tank 200 is tiltedly mounted on the mounting frame 100, and a feed port 250 is provided at one end of the stirring tank 200, and a discharge port is provided at the other end, a storage chamber 260 is provided on one side of the stirring tank 200 close to the feed port 250, and the storage chamber 260 is arranged in an annular structure, a liquid inlet hole 270 is provided on the surface of the stirring tank 200, and the liquid inlet hole 270 is communicated with the inside of the storage chamber 260, and a plurality of liquid outlet holes 280 are provided in an annular array at one end of the storage chamber 260 close to the discharge port, and the liquid outlet hole 280 is communicated with the stirring chamber 290 inside the stirring tank 200.
[0027] Specifically, when in use, aggregates and other solid mixing raw materials are put into the mixing tank 200 through the feed port 250. In order to enable the mixing tank 200 to achieve a better mixing effect in a shorter time during mixing, mixing water needs to be injected into the storage chamber 260 through the liquid inlet hole 270. Since the storage chamber 260 is provided with a plurality of liquid outlet holes 280 in a circular array at one end close to the discharge port, when the mixing tank 200 is mixing, the mixing water in the storage chamber 260 will flow out from different liquid outlet holes 280 in order and be mixed into the mixing raw materials, thereby ensuring that the mixing raw materials can be evenly mixed with water during the mixing process.
[0028] When the above-mentioned automatic speed regulation type uniform stirring and sand mixing device is in use, aggregates and other solid stirring raw materials are put into the stirring tank 200 through the feed port 250. In order to enable the stirring tank 200 to achieve a better stirring effect in a shorter time during stirring, stirring water needs to be injected into the storage chamber 260 through the liquid inlet hole 270. Since a plurality of liquid outlet holes 280 are provided in a circular array at one end of the storage chamber 260 close to the discharge port, when the stirring tank 200 is stirring, the stirring water in the storage chamber 260 will flow out from different liquid outlet holes 280 in order and be mixed into the stirring raw materials, thereby ensuring that the stirring raw materials can be evenly mixed with water during the stirring process, so that the stirring can be more uniform, achieving the effect of reducing time and faster stirring.
[0029] In one embodiment, the mounting frame 100 includes a folding frame 110, a first inclined plate 120 and a second inclined plate 130; the two ends of the folding frame 110 are arranged in a vertical structure, the first inclined plate 120 and the second inclined plate 130 are parallel to each other and are respectively connected to the two ends of the folding frame 110, and the two ends of the mixing tank 200 are respectively rotatably mounted on the first inclined plate 120 and the second inclined plate 130.
[0030] Specifically, since the stirring tank 200 is located as a whole in the space formed by the folding frame 110, the first inclined plate 120 and the second inclined plate 130, when the stirring tank 200 is placed, one end of the folding plate can be close to the wall, and the bottom end of the guide hopper can be opposite to the feed port 250 to facilitate the pouring of stirring materials. At the same time, the external structure of the device is relatively small, so that the size of the stirring tank 200 can be independently selected according to the application site, and since the stirring solid material and stirring water inside it are added in batches, the stirring material inside the stirring tank 200 is relatively uniform during stirring, so it can effectively avoid increasing the compliance of the stirring mechanism and avoid reducing the rotation speed of the stirring device, thereby affecting the stirring effect.
[0031] In one embodiment, the stirring tank 200 includes a spherical tank body 210 and two rotating heads 240; the central axes of the two rotating heads 240 coincide and are respectively fixed on both sides of the tank body 210, and the two rotating heads 240 are respectively rotatably installed on the first inclined plate 120 and the second inclined plate 130. A feed port 250 is opened on the rotating head 240 installed on the first inclined plate 120, and the feed port 250 passes through the interior of the tank body 210. A discharge port is opened on the rotating head 240 installed on the second inclined plate 130, and the discharge port passes through the interior of the tank body 210, and a plug is installed in the discharge port.
[0032] Specifically, the plug is used to close the discharge port. After the mixing is completed, the plug can be removed to allow the mixed material inside the mixing tank 200 to be discharged from the discharge port. A drive motor 500 is installed on the side of the second inclined plate 130 away from the first inclined plate 120. The drive motor 500 is used to drive the rotating head 240 installed on the second inclined plate 130 to rotate. Since the first inclined plate 120 and the second inclined plate 130 are both inclined, and there is an angle between the second inclined plate 130 and the lower surface of the folding plate, the angle is used to set the drive motor 500, which can effectively reduce the occupied space and avoid bumps caused by the external environment.
[0033] In one embodiment, the stirring tank 200 includes a spherical tank body 210, an annular plate 220 and a plurality of limiting rods 230; one end of the annular plate 220 is connected to the inner surface of the tank body 210 on one side close to the feed port 250, and the other end of the annular plate 220 is connected to the inner surface of the tank body 210 on one side close to the discharge port. The surface of the annular plate 220 is curved, and the annular plate 220 divides the internal space of the tank body 210 into a storage chamber 260 and a stirring chamber 290. A plurality of limiting rods 230 are bent and fitted on the inner surface of the stirring chamber 290, and the plurality of limiting rods 230 are arranged in a circular array structure.
[0034] Specifically, the two ends of the annular plate 220 are vertically arranged and the middle end is curved. This structure ensures that after the stirring water is injected into the storage chamber 260, the water body can always be located in the lower half of the storage chamber 260 to avoid flowing out from the liquid outlet 280. The liquid inlet is located on the side of the storage chamber 260 close to the feed port 250, and there are multiple liquid inlets arranged in a circular array. The liquid outlet is located at the end of the annular plate 220 away from the feed port 250.
[0035] In one embodiment, an internal support frame 300 is provided inside the tank body 210, and the internal support frame 300 includes a first support rod 310 and a plurality of second support rods 320; the central axis of the first support rod 310 coincides with the central axis of the rotating head 240, one end of the first support rod 310 is connected to the inner surface of the tank body 210, and the other end of the first support rod 310 is respectively connected to one end of a plurality of second support rods 320, the second support rod 320 is bent, and the end away from the first support rod 310 is connected to the surface of the annular plate 220.
[0036] Specifically, each second support rod 320 is provided with a stirring member 400, and the stirring member 400 includes a first straight plate 410, a second straight plate 420, a first bent plate 430 and a second bent plate 440; one end of the first straight plate 410 is connected to a second support rod 320, one end of the second straight plate 420 is connected to the first support rod 310, the other end of the first straight plate 410 is connected to the other end of the second straight plate 420, and forms a corner matching the connection between the annular plate 220 inside the stirring chamber 290, the first bent plate 430 is arranged on the side of the first straight plate 410 away from the second support rod 320, and the second bent plate 440 is arranged on the side of the second straight plate 420 away from the first support rod 310.
[0037] In one embodiment, a plurality of communication openings are provided on one side where the first straight plate 410 or the second straight plate 420 is connected to the first bent plate 430 or the second bent plate 440 , and the plurality of communication openings are arranged at intervals.
[0038] Specifically, the provision of the communication port can greatly reduce the resistance encountered by the stirring element 400 when stirring the stirring material, thereby preventing the bending or deformation of the stirring element 400 caused by excessive resistance.
[0039] In one embodiment, a plurality of limiting arc protrusions 620 are arranged in a circular array on one side of the surface of the tank body 210 facing the first inclined plate 120 , and an adjusting member 610 is installed on the first inclined plate 120 . The adjusting member 610 can move along the direction of the first inclined plate 120 and abut against the limiting arc protrusion 620 .
[0040] Specifically, a spring is further provided between the adjusting member 610 and the first inclined plate 120 , so as to enable the adjusting member 610 to move linearly when limited by the limiting arc protrusion 620 .
[0041] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
