Description

Technical Field

[0001] The invention belongs to the technical field of wall and floor grooving equipment for building decoration and renovation, and particularly relates to a water-adding dust-removing grooving machine. Background Art

[0002] The common features of the existing water-adding dust removal slotting machines used for building decoration and renovation are:

[0003] 1. The existing water-adding and dust-removing slotting machine has defects in the design of the grinding wheel cover. When the construction workers add water to slot, the centrifugal force generated by the rotation of the cutting blade will prevent the sewage generated by cutting from being discharged in a centralized manner. The sewage is easy to splash onto the bodies of the construction workers. Especially when the natural environment temperature is low, the construction workers must wear waterproof clothes and trousers, otherwise they will find it difficult to endure the cold caused by the sewage splashing onto their clothes and trousers.

[0004] 2. In the existing water-added dust removal slotting machine, since there is no area dividing baffle on the grinding wheel cover, the fine sand carried by the sewage generated by cutting circulates in the space formed by the grinding wheel cover and the cutting disc for a long time. Although the first bearing connected to the front cover and the main shaft is connected with a dust cover, the fine sand carried by the sewage will enter the first bearing and damage the first bearing when it is in this working state for a long time, and the bearing causes the service life of the whole water-added dust removal slotting machine to be short.

[0005] 3. For the water-added dust removal slotting machine, when cutting vertical wall cable grooves according to normal usage habits, the slotting machine's head should be upward and the tail downward, and the slotting machine body should maintain an angle with the vertical wall for cutting. In this way, the sewage generated by the water-added dust removal cutting will flow from top to bottom along the body, naturally to the rotor cooling air inlet position provided on the handle shell connected to the rear of the casing. The negative pressure generated by the rotation of the rotor cooling fan will suck the sewage and the fine sand it carries into the chamber of the casing, damaging the commutator, the third bearing and the fourth bearing connected to the rotor main shaft. After long-term use, the fine sand carried by the sewage will damage the winding insulating paint on the stator and rotor. If more sewage enters, leakage will occur and hurt the construction workers. Due to the unreasonable design of the rotor cooling air inlet position, 100% of the existing water-added dust removal slotting machines are used with the head downward and the tail upward to cut the vertical wall cable grooves, which is extremely inconvenient to use.
