[0004] The aforementioned patent has the following drawbacks: if the No. 1 motor is located inside the mixing tank, it will not only affect the mixing of materials, but also affect the use of the motor. Furthermore, the vibration of the motor during use will also affect the raising and lowering of the stirring rod. In addition, the power cord used to drive the motor will also affect the mixing of materials.

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1 to 4A raw material mixing device for producing a retarding high-efficiency water-reducing agent includes a mixing tank 1. A stirring rod 2 is reciprocated inside the mixing tank 1. A drive device 3 for driving the stirring rod 2 and a centrifugal structure 4 used in conjunction with the drive device 3 to achieve the reciprocating motion of the stirring rod 2 are provided on the upper surface of the mixing tank 1. The drive device 3 includes a first drive motor 301, a splined sleeve 302 rotatably mounted inside the mixing tank 1, a splined shaft 303 fixedly mounted on the top of the stirring rod 2 and slidingly engaged with the splined sleeve 302, a transmission gear 305 fixedly mounted on the output shaft of the first drive motor 301, and a driven gear 304 fixedly mounted on the outer surface of the splined sleeve 302 and meshing with the transmission gear 305. A rotating hole is provided inside the mixing tank 1, and a bearing connected to the outer surface of the splined sleeve 302 is installed in the rotating hole. Through the arrangement of the splined sleeve 302 and the splined shaft 303, the centrifugal structure 4 can be used to achieve the up-and-down reciprocating motion of the stirring rod 2.

[0026] In this embodiment, the centrifugal structure 4 includes a rotating shaft 401 rotatably mounted on the upper surface of the mixing tank 1, a drive structure 402 disposed on the mixing tank 1 and the rotating shaft 401, a mounting base 403 welded to the top end of the rotating shaft 401, a swing arm 404 hingedly mounted on the mounting base 403, a rotating sleeve 406 and a sliding sleeve 407 sleeved on the outer surface of the rotating shaft 401, a swing ball 405 welded to the other end of the swing arm 404, and a connecting rod 408 hingedly mounted between the rotating sleeve 406 and the swing arm 404. The rotating sleeve 406 is rotatably mounted on the outer surface of the sliding sleeve 407, which is sleeved on the outer surface of the rotating shaft 401. The outer surface of the sliding sleeve 407 is provided with a connecting structure 409 connected to the splined shaft 303. The drive structure 402 includes a second drive motor 4021 fixedly mounted on the upper surface of the mixing tank 1 and a linkage gear 4023 fixedly mounted on the outer surface of the rotating shaft 401. An intermittent gear 4022 that intermittently meshes with the linkage gear 4023 is fixedly mounted on the output shaft of the second drive motor 4021. The connecting structure 409 includes a first push arm 4091 hingedly mounted on the outer surface of the sliding sleeve 407, a connecting sleeve 4093 rotatably mounted on the outer surface of the top end of the splined shaft 303, and a second push arm 4092 hingedly mounted on the outer surface of the connecting sleeve 4093. The first push arm 4091 and the second push arm 4092 are hinged at adjacent ends.

[0027] Specifically, the second push arm 4092 is vertically positioned, while the first push arm 4091 is inclined. There are two swing arms 404, two swing balls 405, and two connecting rods 408, with the two swing arms 404 symmetrically arranged. The swing ball 405 has a certain weight; when the rotating shaft 401 rotates, it drives the swing arm 404 to rotate. The swing arm 404 expands outwards due to centrifugal force generated by the rotation of the swing ball 405, thereby causing the sliding sleeve 407 to move upwards, which, in conjunction with the connecting structure 409, pushes the stirring rod 2.

[0028] To achieve the reciprocating function, a reset structure is provided on the outer surface of the rotating shaft 401. The reset structure includes a mounting ring 410 rotatably mounted on the outer surface of the rotating shaft 401, and a reset spring 411 is fixedly connected between the mounting ring 410 and the sliding sleeve 407. The mounting ring 410 is located below the sliding sleeve 407, and the reset spring 411 surrounds the outer surface of the rotating shaft 401. Through the deformation of the reset spring 4011, in conjunction with the intermittent meshing of the intermittent gear 4022 and the linkage gear 4023, the up-and-down reciprocating motion of the stirring rod 2 is achieved.

[0029] In addition, a support frame for the first swing arm 4091 can be installed on the upper surface of the mixing tank 1. The first swing arm 4091 is rotatably mounted on the outer surface of the support frame so as to better push the second swing arm 4092.

[0030] The working principle of the above embodiments is as follows:

[0031] In use, the spline sleeve 302 is rotated by the transmission cooperation of the first drive motor 301, the transmission gear 305, and the driven gear 304. The rotation of the spline sleeve 302 drives the stirring rod 2 to rotate through the spline shaft 303, thereby achieving the mixing of raw materials for the production of retarding high-efficiency water-reducing agent. When the stirring rod 2 needs to be reciprocated, the rotating shaft 401 is intermittently driven by the transmission cooperation of the second drive motor 4021, the intermittent gear 4022, and the linkage gear 4023. When the rotating shaft 401 rotates, it drives the pendulum. When the boom 404 rotates, the swing arm 404 expands outward due to centrifugal force generated by the rotation of the swing ball 405. This expansion is caused by the connecting rod 408, which drives the sliding sleeve 407 to move upward. The upward movement of the sliding sleeve 407 drives the first push arm 4091. At this time, the first push arm 4091 squeezes the second push arm 4092, causing the spline shaft 303 to drive the stirring rod 2 to move downward. Then, through the deformation of the return spring 4011, and in conjunction with the intermittent meshing of the intermittent gear 4022 and the linkage gear 4023, the stirring rod 2 moves up and down reciprocatingly.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
