In addition, when the stirring rod 2 rotates around the vertical axis for stirring, the switching mechanism only enables the stirring hook 201 exposed out of the liquid level 19 or the material surface to spray water, so that the problem that the water spraying capability of the stirring hook 201 in the material is weak during stirring is solved, the stirring rod is mainly used as a stirring part, the function is more clear, dust raised during stirring (particularly dust thrown out by horizontal rotation) is covered by water mist formed by rotation of the stirring hook 201 on the upper part, full dust fall is achieved, and meanwhile, the water adding effect is achieved. The stirring equipment provided by the embodiment has various working modes, and is mainly characterized in that the two modes are combined in sequence, and in the actual engineering application, a person skilled in the art is required to discriminate specific working conditions based on the principle explanation, so that the excellent performance of the stirring equipment can be fully exerted.
Preferably, the reversing mechanism 4 can also adopt a pure mechanical structural design so as to avoid the environmental limitation requirement during a plurality of electrical controls, and has stronger adaptability and is more convenient for self-maintenance of general operators. As shown in fig. 2 to 3, one of the structures of the reversing mechanism 4 is: the water supply device comprises a sliding pipe 11 which is coaxially arranged at the symmetrical center of a stirring rod 2, wherein the sliding pipe 11 can be axially and slidably arranged in an inner reaming section of the stirring rod 2 serving as a water supply channel, the diameter of the inner reaming section is larger than that of other hole sections of the stirring rod 2, and the middle part of the inner reaming section is communicated with a main water supply hole 10. The middle of the tube hole of the sliding tube 11 is provided with a partition plug 1101 which divides the tube hole into two mutually independent sections, the tube wall of the sliding tube 11 near two end surfaces of the partition plug 1101 is provided with a drainage hole 1102, the length and the weight of the sliding tube 11 are such that when one stirring hook 201 is not under the liquid level 19 and the other stirring hook 201 is exposed out of the liquid level 19, the sliding tube 11 slides downwards to the bottom end step of the inner reaming section due to the self weight, and at the moment, the water supply main hole 10 is only communicated with the drainage hole 1102 at the upper part of the two drainage holes 1102, so that high-pressure water flow is sprayed out from the surface of the stirring hook 201 exposed out of the liquid level 19. In order to allow the sliding tube 11 to be moved down better when the agitating shaft 2 is rotated so that the above-mentioned water feed hole 10 is aligned and communicated with the drainage hole 1102 more accurately, the longer the sliding tube 11 is, the better the sliding velocity of the sliding tube 11 caused by gravity is increased. The design of the sliding pipe 11 is characterized in that when the stirring hook 201 rotates around a vertical axis in a posture of one above the other, one left above the other, the larger the rotating speed is, the more the sliding pipe 11 is tightly attached to the bottom end step of the inner reaming section, so that the position state of the main water supply hole 10 and the corresponding drainage hole 1102 which are aligned and communicated is more stable, the conduction state is ensured to be maintained, and the stirring device is particularly suitable for stirring equipment with a large stirring range, and the size advantage of the stirring rod 2 is fully utilized.
In order to realize the new advantages of the above-mentioned mechanical reversing mechanism 4, as shown in fig. 4, another more simplified and pure mechanical structure of the above-mentioned reversing mechanism 4 is as follows: a core 12 is slidably installed in a rod hole serving as the water supply passage at the middle section of the stirring rod 2 where the main water supply hole 10 is located, the core 12 divides the rod hole into two parts independent of each other, and the core 12 has a structure and a size capable of completely sealing the main water supply hole 10. Specifically, two ends of the core 12 are respectively connected in the rod holes through a conical spring 13, the large end of the conical spring 13 is fixedly connected in the rod hole, the small end is connected with the end part of the core 12, the elasticity of the conical spring 13 is required to enable the core 12 to slide downwards to the lower part of the water supply main hole 10 due to the self weight when one stirring hook 201 is not under the liquid level 19 and the other stirring hook 201 is exposed out of the liquid level 19, so that the water supply main hole 10 is communicated with only the part of the rod holes above the core 12, and the high-pressure water flow is sprayed out from only the surface of the stirring hook 201 exposed out of the liquid level 19. The core 12 connected with the conical spring 13 can also function as the sliding tube 11 to adjust the water flow direction of the water supply main hole 10, and the core 12 is substantially similar to the sliding partition plug 1101, and the communication relation between the water supply main hole 10 and the two hole sections of the rod hole of the stirring rod 2 is changed by the sliding of the core 12 in the inclined direction under the self-weight.
