Description

Technical Field

[0001] The utility model relates to the technical field of structural transformation of grading equipment, in particular to a protective cap with a concave wear-resistant bolt. Background Art

[0002] The classifier is widely used in the metal beneficiation process to classify the particle size of the ore pulp. It can also be used for desludging and dehydration in the ore washing operation. It often forms a closed-loop process with the ball mill. In the prior art, the coarse material is screwed into the mill feed port using the spiral classifier blades. However, due to the large particle size of the beneficiation ore, the classifier blades are severely worn, causing the screw caps that fix the blades to fall off after being worn out. This can easily cause the large blades inside the classifier to fall into the classifier, which can easily affect the normal operation of the spiral classifier and have to be stopped for processing. The bolts in the prior art directly rub against the ore and ore pulp, and there is no good protection structure. To this end, we propose a concave wear-resistant bolt protection cap. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a concave wear-resistant bolt protection cap.

[0004] The technical solution adopted by the utility model to solve the technical problem is a concave wear-resistant bolt protective cap, comprising a ring body, a ring body for blocking is screwed on the outer circumference of the ring body, and a ball cap for limiting is integrally constructed at one end of the ring body located outside the ring body, and a hemispherical ring that is fitted and connected with the ball cap is screwed on the outer circumference of the ring body;

[0005] The outer peripheral surface of the annular body and the outer peripheral surface of the ring body are both provided with threaded holes for connection, and a screw sleeve body for fastening is screwed and installed inside the threaded hole.

[0006] By adopting the above technical scheme, before the classifier is used, the manganese steel ring body can be welded to the outer periphery of the bolts fixing the large blades of the classifier, so that the manganese steel ring body can be used to protect the bolts, and at the same time, the ring body and the threads on the outer periphery of the ring body are screwed together, so that the ring body can drive the ball cap to be installed on the outer periphery of the ring body and seal the holes on the outer periphery of the ring body, and then the hemispherical ring is screwed together with the threads on the outer periphery of the ring body and forms a hemispherical structure with the ball cap, thereby improving the lubricity of the ring body and the protection performance of the ring body, so that the bolts fixing the blades of the classifier can operate more stably, and the service life of the bolts is increased, the number of stops of the spiral classifier is reduced, the large blades of the spiral classifier are more stable, and the situation of falling due to the wear of the bolt cap is reduced;

[0007] When the ring body drives the ball cap and the ring body to be screwed together, it is convenient to screw the sleeve body and the threaded holes on the outer periphery of the ring body together, and to screw the threaded holes on the outer periphery of the ring body together, so as to improve the stability of the ring body when it is screwed into the inner side of the ring body, so that the ring body drives the ball cap to seal and protect the ring body more stably, thereby improving the protection performance of the ring body.

[0008] Specifically, a plug hole for connection is provided on the inner circumferential surface of the hemispherical ring, and a sliding rod plugged and connected with the plug hole is slidably installed on the inner circumferential surface of the screw sleeve.

[0009] By adopting the above technical solution, when the hemispherical ring is screwed and installed on the outer periphery of the ring body, the sliding rod on the inner side of the screw sleeve body can slide conveniently and extend from one end of the screw sleeve body, and can be plugged into the socket on the inner periphery of the hemispherical ring, thereby improving the stability of the hemispherical ring screwed on the outer periphery of the ring body, and effectively improving the protection performance of the ring body.

[0010] Specifically, an end of the screw sleeve body close to the insertion hole is provided with a straight groove for rotation.

[0011] By adopting the above technical solution, the straight groove at one end of the screw sleeve body enables the screw sleeve body to be easily rotated, so that the screw sleeve body can be easily screwed into the threaded hole and easily disassembled.

[0012] Specifically, a plug for sealing is threadedly installed at one end of the screw sleeve body away from the insertion hole, and a spring located between the slide rod and the plug is arranged inside the screw sleeve body.

[0013] By adopting the above technical solution, the plug at one end of the screw sleeve body is convenient for sealing the hole at this end, so that the spring in the screw sleeve body can operate stably, and the spring can easily push the slide rod back, so that one end of the slide rod can stably extend out of the screw sleeve body and be plugged into the socket, which is convenient for improving the stability of the connection between the slide rod and the socket.

[0014] Specifically, the top surface of the ball cap and the outer peripheral surface of the hemispherical ring are both provided with concave holes for rotation, and there are multiple groups of concave holes.

[0015] By adopting the above technical solution, the concave hole makes it more convenient to install the ball cap and the hemispherical ring.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application, through the design of the ring body, the ball cap, the hemispherical ring and the ring body, can weld the manganese steel ring body to the outer periphery of the bolts fixing the large blades of the classifier before the classifier is used, so that the manganese steel ring body can be used to protect the bolts, and at the same time, the ring body and the threads on the inner periphery of the ring body are screwed together, so that the ring body can drive the ball cap to be installed on the outer periphery of the ring body and seal the holes on the outer periphery of the ring body, and then the hemispherical ring is conveniently screwed with the threads on the outer periphery of the ring body to form a hemispherical structure with the ball cap, thereby improving the lubricity of the ring body and the protection performance of the ring body, so that the bolts fixing the blades of the classifier can operate more stably, increase the service life of the bolts, reduce the number of stops of the spiral classifier, make the large blades of the spiral classifier more stable, and reduce the situation of falling due to the wear of the bolt caps.

[0018] 2. The technical solution of the present application adopts the design of the threaded hole and the screw sleeve body.
