Currently, grinding machines are used to finely grind sand and gravel aggregates.

[0003] However, the feed inlet of the current grinding mill lacks an anti-clogging mechanism. When the sand and gravel aggregate passes through the feed inlet, it is easy to get clogged, which affects the use of the grinding mill. In addition, the feed inlet of the grinding mill lacks a dust prevention mechanism, which generates a lot of dust when dumping aggregate, polluting the surrounding air environment.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This fine grinding device for sand and gravel aggregate processing is equipped with an anti-clogging component group and a dust reduction component group. Currently, the feed inlet of grinding mills lacks an anti-clogging mechanism, and sand and gravel aggregates are prone to clogging when passing through the feed inlet, affecting the use of the grinding mill. In the design, the rotation position of the stirring rod and the sleeve body is at the feed position between the feed cylinder and the guide trough of the grinding mill. It can evenly disperse the sand and gravel aggregates through rotation and guide them to smoothly enter the feed inlet of the grinding mill, avoiding the problem of feed inlet blockage caused by too much feed at one time. This reduces the need for operator intervention, reduces the frequency of manual cleaning of blockages, and thus improves the automation and safety of production.

[0015] 2. This fine grinding device for sand and gravel aggregate processing is equipped with an anti-clogging component group and a dust suppression component group. Currently, the feed inlet of the grinding machine lacks a dust prevention mechanism, which generates a large amount of dust when dumping aggregate, polluting the surrounding air environment. In the corresponding dust suppression component group, by starting the blower connected to the air inlet pipe, the blower will blow air into the upper cylinder shell through the air inlet pipe. The air blower will pass through the upper cylinder shell, and the dust generated by dumping sand and gravel aggregate will be carried by the airflow through the ventilation opening of the air inlet pipe and the frame plate into the non-woven bag. The dust will be blocked by the non-woven bag and cannot pass through, while the airflow will pass through the non-woven bag and be discharged. After the non-woven bag is full of dust, the frame plate and non-woven bag can be removed from the upper cylinder shell for cleaning by unscrewing the screws. This design has a simple structure and can be directly installed on the anti-clogging component group, which can reduce the dust generated by feeding. Attached Figure Description

[0024] Please see Figure 1-6 This utility model provides an embodiment of a fine grinding device for processing sand and gravel aggregates, including a fine grinding mill component group 01. The fine grinding mill component group 01 includes a grinding mill body 11 and a grinding mill feed cylinder 12. The grinding mill feed cylinder 12 is connected to the top of the grinding mill body 11. An anti-clogging component group 02 is provided on the grinding mill feed cylinder 12 to prevent clogging when the grinding mill feed cylinder 12 is feeding. The anti-clogging component group 02 includes a guide box 21, which is connected to a first frame cylinder 23 and a second frame cylinder 27. A servo motor 22 is provided on the side of the guide box 21. A rotating shaft 24 is connected to the working end of the servo motor 22. A sleeve body 25 and a stirring rod 26 are provided on the outside of the rotating shaft 24. A dust-reducing component group 03 is provided on the top of the anti-clogging component group 02 to reduce the dust generated when sand and gravel aggregates enter the anti-clogging component group 02 and the grinding mill feed cylinder 12.

[0025] The guide box 21 is connected to the top of the feed cylinder 12 of the grinding machine through a through groove. The top of the guide box 21 is provided with an opening. The first support cylinder 23 and the second support cylinder 27 are connected by bearings and rotating shaft 24.

[0026] The servo motor 22 is mounted on the grinding machine body 11 via a mounting bracket, and the sleeve body 25 is connected to the rotating shaft 24.

[0027] Multiple stirring rods 26 are provided, and the multiple stirring rods 26 are evenly distributed on the outside of the sleeve body 25, and the stirring rods 26 are connected to the sleeve body 25.

[0028] The dust suppression component assembly 03 includes an upper cylinder shell 31, an air inlet duct 32 is provided on the side of the upper cylinder shell 31, a frame plate 33 and a non-woven bag 34 are provided on the other side of the upper cylinder shell 31, and screw parts 35 are provided inside the frame plate 33.

[0029] The upper shell 31 is connected to the guide slot box 21, and the air inlet pipe 32 is connected to the side of the upper shell 31 through the slot. The air inlet pipe 32 is connected to the blower.

[0030] The side of the upper shell 31 away from the air inlet duct 32 is connected to the non-woven bag 34 by a screw 35. The screw 35 is connected to the frame plate 33 and the upper shell 31 by a thread. The non-woven bag 34 is connected to the frame plate 33. The upper shell 31 is provided with a ventilation opening at the position corresponding to the frame plate 33.

[0031] Working Principle: Currently, grinding mills lack anti-clogging mechanisms at the feed inlet, making it prone to clogging when sand and gravel aggregates pass through, affecting the operation of the grinding mill. The corresponding anti-clogging component group 02 and dust suppression component group 03 are designed to directly pour the sand and gravel aggregates requiring fine grinding through the top opening of the guide box 21 into the guide box 21. The sand and gravel aggregates are guided by the structure of the guide box 21 into the grinding mill feed cylinder 12, and then enter the grinding mill body 11 for fine grinding. When passing through the feed inlet of the grinding mill feed cylinder 12, due to the servo... Driven by the servo motor 22, the rotating shaft 24 and the sleeve 25 rotate through the working end. The sleeve 25 drives the stirring rod 26 to rotate. The rotating position of the stirring rod 26 and the sleeve 25 is at the feeding position between the feed cylinder 12 and the guide box 21 of the grinding mill. The rotation can evenly disperse the sand and gravel aggregate and guide it to enter the feed inlet of the grinding mill smoothly, avoiding the problem of excessive feed entering at one time, which may cause the feed inlet to be blocked. This reduces the need for operator intervention, reduces the frequency of manual cleaning of blockages, and thus improves the automation and safety of production. The current grinding mill lacks a dustproof mechanism at the feed inlet, generating a large amount of dust when dumping aggregates, polluting the surrounding air environment. In the corresponding dust reduction component group 03, by activating the blower connected to the air inlet pipe 32, the blower will blow air into the upper cylinder shell 31 through the air inlet pipe 32. The air blower will pass through the upper cylinder shell 31, and the dust generated by dumping sand and gravel aggregates will be carried by the airflow through the ventilation opening of the air inlet pipe 32 and the frame plate 33 into the non-woven bag 34. The dust will be blocked by the non-woven bag 34 and cannot pass through, while the airflow will pass through the non-woven bag 34 and be discharged. After the non-woven bag 34 is full of dust, the frame plate 33 and the non-woven bag 34 can be removed from the upper cylinder shell 31 for cleaning by unscrewing the screw part 35. This design has a simple structure and can be directly installed on the anti-clogging component group 02 device, which can reduce the dust generated by feeding.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
