Specific Embodiment

[0011] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0012] Refer to Figures 1 to 3 , a mixer for concrete processing, including a support frame one 1, a support frame three 3 and a mixing bin 301. The upper part of the support frame three 3 is fixedly installed with the mixing bin 301. The upper part of the support frame one 1 is installed with a motor 101. The output shaft of the motor 101 is fixedly connected with a connecting rod one 102. The connecting rod one 102 is rotationally connected with a rotary feeding mechanism. The rotary feeding mechanism is slidably connected to the mixing bin 301 back and forth and stirs the inside of the mixing bin 301 and brushes the inner wall.

[0013] Preferably, the rotary feeding mechanism includes: a second connecting rod 103 and a mounting seat 201. One end of the second connecting rod 103 is rotatably connected to the first connecting rod 102 through a connecting shaft. The other end of the second connecting rod 103 is connected to a connecting ball head 104. Inside the connecting ball head 104, a connecting ball core 1051 is rotatably connected. One end of a third connecting rod 105 is fixedly connected to the connecting ball core 1051. The third connecting rod 105 passes through the mounting seat 201 on the outside. The length of the second connecting rod 103 is greater than the length of the first connecting rod 102. The motor 101 drives the first connecting rod 102 to rotate. At this time, it will drive the rotatably connected second connecting rod 103 to rotate. However, since the ball head of the second connecting rod 103 is connected to the third connecting rod 105, and the third connecting rod 105 is slidably connected inside the mounting seat 201, and the length of the second connecting rod 103 is greater than the length of the first connecting rod 102, when the first connecting rod 102 rotates, it will drive the third connecting rod 105 to move back and forth in the mounting seat 201.

[0014] Preferably, a circular groove 202 is provided in the middle of the mounting seat 201. The diameter of the circular groove 202 is at least greater than or equal to the diameter of the third connecting rod 105. The third connecting rod 105 is placed inside the circular groove 202. A spiral groove 2021 is provided inside the circular groove 202. A limiting protrusion 1052 is slidably connected inside the spiral groove 2021. The limiting protrusion 1052 is spherical and is fixedly connected to the middle of the third connecting rod 105. The third connecting rod 105 is slidably connected to the mixing chamber 301. On one side of the end of the third connecting rod 105, a plurality of stirring rods 106 are fixedly connected. The end of the stirring rod 106 is connected to a brush hair 107. The stirring rod 106 extends into the mixing chamber 301. Because the spiral groove 2021 is provided inside the mounting seat 201 and the limiting protrusion 1052 is provided on the third connecting rod 105, when the third connecting rod 105 moves back and forth, it will drive the limiting protrusion 1052 to rotate in the spiral groove 2021, thereby causing the third connecting rod 105 to rotate. Therefore, when the motor 101 drives the first connecting rod 102 to rotate, it will drive the third connecting rod 105 to move back and forth and rotate itself in the mounting seat 201. Since the stirring rod 106 is fixedly connected to the front end of the third connecting rod 105, it will drive the stirring rod 106 to rotate, so as to make the stirring rod 106 stir in the mixing chamber 301. At the same time, because the brush hair 107 is provided at the end of the stirring rod 106, when the stirring rod 106 rotates, the brush hair 107 can brush the side wall of the mixing chamber.

[0015] Working principle: When in use, start the motor 101. The motor 101 drives the first connecting rod 102 to rotate. At this time, it will drive the second connecting rod 103 that is rotatably connected to rotate. However, since the second connecting rod 103 is ball-connected to the third connecting rod 105, and the third connecting rod 105 is slidably connected inside the mounting seat 201, and the length of the second connecting rod 103 is greater than the length of the first connecting rod 102. Therefore, when the first connecting rod 102 rotates, it will drive the third connecting rod 105 to move back and forth in the mounting seat 201. But because there is a spiral groove 2021 inside the mounting seat 201, and a limiting protrusion 1052 is provided on the third connecting rod 105. So when the third connecting rod 105 moves back and forth, it will drive the limiting protrusion 1052 to rotate in the spiral groove 2021, thereby causing the third connecting rod 105 to rotate. Therefore, when the motor 101 drives the first connecting rod 102 to rotate, it will drive the third connecting rod 105 to move back and forth and rotate itself in the mounting seat 201. And since the front end of the third connecting rod 105 is fixedly connected to the stirring rod 106, it will drive the stirring rod 106 to rotate, so that the stirring rod 106 stirs in the mixing chamber 301. At the same time, because there are bristles 107 at the end of the stirring rod 106, it can cause the bristles 107 to brush the side wall of the mixing chamber when the stirring rod 106 rotates.
