Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of knock column and the grinding mechanism composed of it, specifically a kind of plum blossom knock column and the grinding mechanism composed of it, belong to the technical field of grinding machine accessories. BACKGROUND

[0002] Grinding machine is widely used due to its simple structure and high grinding efficiency. Its working principle is that the material to be crushed is thrown out by the knock column on the high-speed rotating grinding disc in the tangential direction, impacting the gear ring, and then broken in the grinding area of the grinding machine. Under the action of the fan, it enters the separation area from the inner wall downward along the outer wall of the reflux ring, and then is ejected from the discharge port after passing through the fan blade classifier. Currently, the knock column installed on the grinding disc is generally cylindrical in structure. For example, the patent with publication number CN210753092U discloses a grinding disc type grinding machine with guide vanes. As can be clearly seen from the attached drawings, the replaceable knock column is cylindrical. The cylindrical knock column has a point contact with the material, a small breaking surface area, and a low crushing efficiency. The collision frequency is also low, and the grinding effect is poor. Currently, there are also non-cylindrical knock columns. However, the above-mentioned knock columns require changes to other accessories in the original grinding machine that cooperate with the knock column, resulting in complex structure and high modification cost. SUMMARY

[0003] The utility model aims to solve the problems of low breaking efficiency and poor breaking effect of the existing cylindrical knock column, as well as the complex structure and high modification cost of the grinding machine caused by changing the knock column. It provides a plum blossom knock column and a grinding mechanism composed of it. The plum blossom knock column has a surface contact with the material, a large breaking surface area, and a high collision frequency, thereby improving the crushing efficiency and effect. At the same time, the plum blossom knock column can cooperate with the original structure without the need to change the original structure, resulting in low use cost.

[0004] To solve the above problems, the plum blossom knock column of the present application is realized by the following technical scheme:

[0005] A plum blossom knock column includes a knock column body. The special feature is that a plurality of impact teeth are uniformly spaced in the circumferential direction of the knock column body. The impact teeth are arc column structures surrounded by a convex surface projecting from the knock column body and the arc surfaces on both sides of the convex surface. The adjacent two impact teeth are connected by an arc surface.

[0006] Preferably, the convex surface is a plane or a curved surface.

[0007] Preferably, one end of the impact tooth is aligned with the knock column body, and the other end is shorter than the knock column body.

[0008] Preferably, the impact tooth has at least three.

[0009] Preferably, the end of the striking post body extending from the impact tooth is provided with a retaining spring groove;

[0010] The grinding mechanism composed of the above-mentioned plum blossom-shaped impact columns includes a grinding disc, and its special feature is that multiple plum blossom-shaped impact columns are uniformly installed on the grinding disc;

[0011] Preferably, the grinding disc is provided with a plurality of plum blossom-shaped hammer mounting holes evenly distributed on it, and the plum blossom-shaped hammer mounting holes are through holes;

[0012] Preferably, the plum blossom-shaped impact pin has at least three mounting holes;

[0013] Preferably, the hammer body of the plum blossom hammer is fixedly installed in the plum blossom hammer mounting hole. Preferably, the hammer body is installed in the plum blossom hammer mounting hole and fixed by a snap ring.

[0014] The plum blossom impact column of this application can be directly installed and used without changing the original structure of the grinding mechanism, reducing the cost of use. Due to the addition of impact teeth, the point contact of the material to be crushed can be changed to surface contact, increasing the crushing area. At the same time, there are multiple impact teeth, and both the convex and arc surfaces of the impact teeth can contact the material to be crushed, increasing the number of impacts and thus improving the crushing efficiency. The crushing efficiency is 30-40% higher than that of the existing cylindrical impact column. The grinding mechanism composed of this plum blossom impact column improves the working efficiency.
