[0002] Concrete additives, also known as concrete admixtures, refer to substances added to improve the performance of concrete before or during the mixing process. There are many types of concrete additives (such as water reducers, air entraining agents, etc.), and different additives have different raw materials. Therefore, in the process of producing and mixing concrete additives, in order to avoid residual effects on the effect of secondary mixing, after the first mixing is completed, the mixing kettle of the mixing ratio needs to be cleaned.

Based on this, a concrete additive production equipment that is easy to clean is provided. Utility Model Content

[0033] The annular tube 206 is rotatably connected to the inner sides of the two C-shaped bases 205, and the nozzle 207 is fixed to the bottom of the annular tube 206;

[0034] The hose 204 is fixed to the top of the lifting tube 203, a rotating groove 2051 is provided inside the C-shaped base 205, an eccentric notch 2052 is provided on the top, and the eccentric notch 2052 is communicated with the inner cavity of the lifting tube 203 and the rotating groove 2051, a water inlet 2061 is provided on the top of the contact position between the annular tube 206 and the C-shaped base 205, and the water inlet 2061 is communicated with the rotating groove 2051, and external flushing water flows into the inner cavity of the annular tube 206 through the hose 204, the lifting tube 203, the eccentric notch 2052, the rotating groove 2051, and the water inlet 2061, and is sprayed out through the nozzle 207 to flush the inner cavity of the kettle body 101 and the outer wall of the stirring motor 104;

[0035] The linkage assembly 208 is distributed in the inner cavity of the rotating groove 2051 and the outer side of the annular tube 206. The linkage assembly 208 drives the annular tube 206 to swing back and forth by utilizing the impact force of the water flow.

[0036] The linkage assembly 208 includes a reciprocating screw 2081, a rotating blade 2082, a reciprocating seat 2083, an inner extrusion block 2084, an outer extrusion block 2085, an n-shaped connecting rod 2086, an inner protrusion 2087 and an outer protrusion 2088;

[0037] The reciprocating screw 2081 is rotatably mounted in the inner cavity of the rotating groove 2051 and penetrates to the outside of the C-shaped base 205. The rotating blades 2082 are fixed to the outer side of the reciprocating screw 2081 and distributed on the inner side of the rotating groove 2051.

[0038] The inner convex block 2087 and the outer convex block 2088 are respectively fixed to the inner and outer sides of the annular tube 206 near the C-shaped base 205, and the inner extrusion block 2084 and the outer extrusion block 2085 are respectively attached to the inner convex block 2087 and the outer convex block 2088 on the side away from each other, and the inner extrusion block 2084 and the outer extrusion block 2085 are connected and fixed by an n-type connecting rod 2086, and the n-type connecting rod 2086 is located above the n-type connecting rod 2086;

[0039] The reciprocating seat 2083 is sleeved on the outside of the part of the reciprocating screw 2081 located outside the rotating groove 2051, and the reciprocating seat 2083 is fixedly connected to the side of the inner extrusion block 2084 away from the inner protrusion 2087. The reciprocating screw 2081 is rotated to drive the reciprocating seat 2083 to reciprocate, driving the inner extrusion block 2084 and the outer extrusion block 2085 to intermittently squeeze the inner protrusion 2087 and the outer protrusion 2088 respectively, thereby realizing the reciprocating swing of the annular tube 206.

[0040] In this embodiment, it should be further explained that the hose 304 is connected to the external water tank through a water pump. After the concrete additive is mixed once and discharged through the discharge port at the bottom of the kettle 101, the inner wall of the kettle 101 can be cleaned by the cleaning component 2. The operation is as follows:

[0041] The external water pump and the electric push rod 201 are started synchronously. The electric push rod 201 drives the lifting pipe 203, the C-shaped base 205, the annular pipe 206, and the nozzle 207 to move downward synchronously through the connecting seat 202. The water pump delivers the water in the water tank to the inside of the annular pipe 206 through the hose 304, the lifting pipe 203, the eccentric notch 2052, the rotating groove 2051, and the water inlet 2061, and sprays it out through the nozzle 207. The sprayed water flow can wash the inner wall of the kettle body 101 and the outer wall of the stirring piece 105 (it should be noted that the nozzle 207 has a multi-head structure and can achieve washing in different directions);

[0042] At the same time, when the water flows into the rotating groove 2051 through the eccentric notch 2052, it will impact the rotating blade 2082, causing the reciprocating screw 2081 to rotate, and the reciprocating screw 2081 drives the reciprocating seat 2084 to reciprocate. When the reciprocating seat 2084 moves toward the outside of the annular tube 206, the inner extrusion block 2084 squeezes the inner protrusion 2087. When the reciprocating seat 2084 moves toward the inside of the annular tube 206, the outer extrusion block 2085 squeezes the outer protrusion 2088. A reciprocating force is provided to the annular tube 206, so that the annular tube 206 reciprocates, thereby making the flushing area of ​​the nozzle 207 more comprehensive, effectively avoiding the occurrence of cleaning dead corners (it should be noted that: a ball matching the spiral groove on the outer wall of the reciprocating screw 2081 is arranged on the inner side of the reciprocating seat 2084, and at the same time, under the mutual fitting and limiting effect of the outer extrusion block 2085 and the outer protrusion 2088, and the inner extrusion block 2084 and the inner protrusion 2087, the reciprocating seat 2084 cannot rotate and can only perform a reciprocating operation).

[0043] Please refer to Figures 2 to 6 There are multiple nozzles 207, which are distributed in an annular manner at the bottom of the annular tube 206, and an arc-shaped slot for the nozzles 207 to move is formed on the top of the C-shaped base 205;

[0044] The reciprocating rotation angle of the annular tube 206 is greater than the distribution angle of two adjacent nozzles 207;

[0045] The total length of the reciprocating trajectory of the water inlet 2061 is smaller than the length of the arc trajectory of the C-shaped base 205 .

[0046] In this embodiment: through the above structure, when the annular tube 206 rotates, the nozzle 207 will not interfere with the C-shaped base 205, and the water inlet 2061 will not be separated from the C-shaped base 205, which effectively ensures the smooth flow of the water channel;

[0047] The structure in which the reciprocating rotation angle of the annular tube 206 is greater than the distribution angle of two adjacent nozzles 207 allows the flushing areas of the nozzles 207 to overlap with each other, thereby avoiding the occurrence of cleaning dead corners.

[0048] Please refer to Figures 2 to 6 The eccentric notch 2052 and the center line of the rotating groove 2051 are offset in the vertical direction, the contact surfaces between the inner protrusion 2087 and the inner extrusion block 2084, and the contact surfaces between the outer protrusion 2088 and the inner extrusion block 2084 are both inclined structures, and two groups of linkage components 208 are arranged along the circumferential trajectory of the annular tube 206.

[0049] In this embodiment, this structure allows the annular tube 206 to be more evenly stressed, and the reciprocating rotation of the annular tube 206 is more stable.

[0050] Please refer to Figures 1-2 When the annular tube 206 is at the highest position, the base material feeding port 102 and the auxiliary material feeding pipe 103 extending to the inside of the kettle body 101 are both located below the nozzle 207.

[0051] In this embodiment, this structure enables the nozzle 207 area to be higher than the position where the material enters the kettle body 101 , thereby preventing the material from adhering to the nozzle 207 .

[0052] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
