Furthermore, the profile of the outer wall of the push plate is consistent with the profile of the inner wall of the groove; so as to ensure the full matching and the fitting of the push plate and the groove and reduce the possibility that powder enters the groove.

Furthermore, a sealing ring is sleeved or embedded on the outer wall of the push plate. Through the setting of sealing washer for form the movive seal cooperation between push pedal and the recess cell wall, thereby further reduction gets into the powder volume in the recess.

Furthermore, both ends of the hob are in running fit with the bearing, and the outer wall of the bearing is fixedly connected with the push plate through a connecting piece. In this scheme at hobbing cutter both ends cooperation bearing, can form normal running fit between bearing inner race and the hobbing cutter to guarantee that the hobbing cutter rotates steadily, the relative push pedal of bearing outer lane keeps motionless, connect through the connecting piece can.

Further, the lower end of the feed opening is communicated with a feed channel; the blanking device is characterized by further comprising a bypass channel, wherein one end of the bypass channel is communicated with the blanking channel, the other end of the bypass channel is communicated with the groove, and a valve is arranged on the bypass channel. For certain powder with extremely small particle size, the powder can enter the groove in any way, and a bypass channel is arranged for the purpose, and the groove is communicated with the blanking channel through the bypass channel. Among the prior art, all have certain negative pressure in the unloading passageway, this is the conventional means of going into and using under the stability of the powder for the convenience, and this negative pressure of this scheme utilization when the powder in the recess is cleared up to needs, opens the valve on the bypass passageway, carries out appropriate suction to the powder in the recess through the negative pressure in the unloading passageway to this function of the automatic clearance of the powder that gets into in the recess can be realized.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

1. the automatic bag breaking mechanism for the powdery additive solves the problems of labor consumption and low efficiency caused by manual bag breaking of the bagged powdery additive when drilling fluid is prepared in the technology, and achieves the purposes of reducing the labor consumption and improving the automation degree of drilling and completion engineering.

2. The automatic bag breaking mechanism for the powdery additive can properly reduce the dust pollution to a charging workshop/workshop.

3. The automatic bag breaking mechanism for the powdery additive can realize automatic cleaning of powder entering the groove.
