[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: a material mixing device, including a base 1 and a trolley 3. An upright frame 101 is fixedly connected to the upper surface of the base 1. A connecting chute 102 is opened on the front surface of the upright frame 101. A support arm 2 is slidably installed in the connecting chute 102. A stirring shaft 202 is rotatably installed in the support arm 2. Two supports 301 are symmetrically and fixedly connected to the upper surface of the trolley 3. A stirring barrel 6 is rotatably installed between the two supports 301. An L-shaped block 601 is fixedly connected to the front surface of the stirring barrel 6. A protrusion 302 is fixedly connected to the front surface of the support 301. A stopper 5 is rotatably installed at the front end of one of the protrusions 302. The stopper 5 cooperates with the L-shaped block 601. An installation chute 104 is opened on the lower surface of the base 1. A collection box 105 is slidably installed in the installation chute 104.

[0023] In this implementation manner, a large amount of materials are placed in the stirring barrel 6. Pushing the trolley 3 can drive the movement of the stirring barrel 6. There is no need to move the stirring barrel 6 by means of carrying, which is convenient for moving the stirring barrel 6 to the position for discharging the mixed materials over a short distance. At the same time, the stirring barrel 6 is rotatably installed between the two supports 301, so that the stirring barrel 6 can rotate by a certain angle, which is convenient for pouring out the materials inside the stirring barrel 6. The stopper 5 cooperates with the L-shaped block 601 to limit the rotation of the stirring barrel 6, so that the stirring barrel 6 is usually in a vertical state, avoiding the problem that the stirring barrel 6 rotates and the internal raw materials pour out due to shaking during the movement of the trolley 3. The trolley 3 can just be stuck inside the base 1, as Figure 1As shown, the height of the collection box 105 is slightly lower than the height of the chassis of the trolley 3. Therefore, when the trolley 3 is stuck in the base 1, the collection box 105 will not interfere with the trolley 3. At this time, the lower moving support arm 2 drives the stirring shaft 202 to insert into the inside of the mixing barrel 6, and the raw materials inside the mixing barrel 6 can be mixed and stirred. After the stirring is completed, the stirring shaft 202 is lifted upward to move it out of the inside of the mixing barrel 6, and the trolley 3 is pushed away. At this time, the materials dripping from the stirring shaft 202 will be caught and collected by the collection box 105, thus avoiding the materials directly dripping on the ground, avoiding material waste and also avoiding ground pollution.

[0024] Among them, in order to achieve the purpose of stirring the materials inside the mixing barrel 6, the present device is realized by the following technical scheme: A hydraulic telescopic rod 103 is fixedly connected inside the connecting chute 102, the upper end of the hydraulic telescopic rod 103 is fixedly connected to the support arm 2, a handle 106 is fixedly connected to the back of the collection box 105, a driving motor 201 is fixedly connected to the upper surface of the support arm 2, the output end of the driving motor 201 is fixedly connected to the stirring shaft 202, a cover plate 203 is rotatably installed on the stirring shaft 202 through a bearing, a clamping block 204 is fixedly connected to the lower surface of the cover plate 203, and the clamping block 204 cooperates with the mixing barrel 6.

[0025] By starting the hydraulic telescopic rod 103, the support arm 2 can be driven to move, so as to control the height of the support arm 2. The handle 106 can drive the collection box 105 to move, which is convenient for pulling out the collection box 105 and installing it inside the chute 104. Starting the driving motor 201 can drive the stirring shaft 202 to rotate. The cover plate 203 is rotatably connected to the stirring shaft 202 through a bearing. Therefore, when the stirring shaft 202 rotates, the cover plate 203 will not be driven to rotate synchronously. The clamping block 204 cooperates with the mixing barrel 6. During the downward movement of the support arm 2, the stirring shaft 202 will drive the cover plate 203 to move downward synchronously, and the cover plate 203 will cover the mixing barrel 6, and the clamping block 204 will be stuck around the mixing barrel 6, avoiding the problem that the mixing barrel 6 shakes and the stirring shaft 202 contacts its inner wall when stirring the materials.

[0026] Among them, in order to achieve the purpose of fixing the bolt 5, the present device is realized by the following technical scheme: A limiting groove 4 is opened on one side of another convex block 302, a return spring 401 is fixedly connected inside the limiting groove 4, the other end of the return spring 401 is fixedly connected to a limiting pin 402, a displacement handle 403 is fixedly connected to the limiting pin 402, a limiting hole 501 is opened inside the bolt 5 and near the position of the other end edge, and the limiting hole 501 cooperates with the limiting pin 402.

[0027] The return spring 401 can provide a certain thrust for the limiting pin 402. The limiting pin 402 is pushed by the thrust and inserts into the inside of the limiting hole 501, so as to fix the limiting hole 501 in the horizontal state, as Figure 1As shown, in order to prevent the stopper 5 from jumping out of the L-shaped block 601 due to vibration during the movement of the trolley 3, the displacement handle 403 can drive the limit pin 402 to move.

[0028] After the mixing is completed, the hydraulic telescopic rod 103 is started to drive the arm 2 to move upward and reset, and the trolley 3 can be pushed to drive the mixing barrel 6 to move to the appropriate position, and the displacement handle 403 is moved to drive the limit pin 402 to move out of the limit hole 501. After the restriction of the stop bolt 5 is released, the stop bolt 5 is rotated to move it out of the L-shaped block 601. Figure 3 As shown, the mixing barrel 6 can be rotated to pour out the mixed materials inside.

[0029] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
