Description

Technical Field

[0001] The utility model relates to the technical field of cone crushers, in particular to a movable cone crushing wall for a cone crusher. Background Art

[0002] Cone crusher is a kind of crushing equipment widely used in mining, metallurgy, construction, chemical industry and other industries. It has a large crushing ratio, high efficiency, low energy consumption, and uniform product particle size. It is suitable for medium and fine crushing of various ores and rocks. It is highly favored for its high efficiency and stable crushing performance and wide applicability to ores of various hardness. The crushing wall, also called the moving plate, is also a very important part of the cone crusher. It often works together with the mortar wall to ensure the normal operation of the cone crusher.

[0003] After searching, Chinese patent announcement number: CN215029246U discloses a new type of crushing wall for cone crusher, including a slide plate and a fixed ring. When the ore falls, part of the ore falls directly into the open buffer bucket, and the other part slides down through the slide plate. The setting of the slide plate has a certain buffering effect on the ore, and the open buffer bucket further buffers the falling ore. In addition, by providing a protective cover located just above the moving cone, the ore is prevented from directly falling and colliding with the moving cone, thereby avoiding damage to the surface of the moving cone, thereby achieving good protection effect and improving the service life of the equipment.

[0004] However, in actual use, when the above-mentioned crushing wall blocks the ore through the protective cover, when the ore falls directly on the protective cover, the ore will come into direct hard contact with the protective cover. At this time, the protective cover will be directly subjected to a large impact force, which will greatly shorten the service life of the protective cover. At the same time, the protective cover is also prone to deformation during the process of ore falling, which in turn affects the protective effect of the moving cone below. Therefore, a cone crusher with a moving cone crushing wall is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a movable cone crushing wall for a cone crusher, aiming to improve the problem in the prior art that when a protective cover is set to protect the upper part of the movable cone, the protective cover will come into hard contact with the falling ore, resulting in a short service life of the protective cover.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a dynamic cone crushing wall for a cone crusher, comprising a crushing wall body, a fixed cone fixedly connected to the lower inner side of the crushing wall body, a dynamic cone body arranged below the fixed cone, an upper protective cover fixedly connected to the upper inner side of the crushing wall body, a buffer bucket fixedly connected to the center of the crushing wall body, a mounting plate arranged inside the buffer bucket, a connecting rod fixedly connected to the outer side of the mounting plate, a lower protective cover arranged above the mounting plate, a buffer unit arranged at the bottom of the lower protective cover, the buffer unit being used to buffer and limit the movement of the lower protective cover, and a buffer rod fixedly connected to the outer side of the lower protective cover.

[0007] As a further description of the above technical solution:

[0008] The buffer unit includes a telescopic rod, which is fixedly connected to the upper surface of the mounting plate. A spring is provided inside the telescopic rod, and a groove is provided on the bottom surface of the lower protective cover.

[0009] As a further description of the above technical solution:

[0010] A limiting groove is provided on the inner wall surface of the buffer bucket, and one end of the buffer rod away from the lower protective cover is located inside the limiting groove.

[0011] As a further description of the above technical solution:

[0012] The inner wall surface of the buffer bucket is fixedly connected with a baffle, the bottom of the mounting plate is provided with a protective plate, the upper surface of the protective plate is fixedly connected with a side plate, and the upper end of the side plate is fixedly connected to the bottom surface of the lower protective cover.

[0013] As a further description of the above technical solution:

[0014] One end of the connecting rod away from the mounting plate is fixedly connected to the inner wall of the buffer bucket, and the connecting rod is located directly below the buffer rod.

[0015] As a further description of the above technical solution:

[0016] The lower protective cover is located directly above the moving cone body.

[0017] As a further description of the above technical solution:

[0018] The upper end of the telescopic rod is fixedly connected to the inner top surface of the groove.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1-Figure 2 The utility model provides an embodiment: a dynamic cone crushing wall for a cone crusher, comprising a crushing wall body 1, a fixed cone 2 fixedly connected to the lower side of the inner part of the crushing wall body 1, a dynamic cone body 3 provided below the fixed cone 2, an upper protective cover 4 fixedly connected to the upper side of the inner part of the crushing wall body 1, the upper protective cover 4 can buffer the ore falling from above, when the ore falls above the upper protective cover 4, it can slide along the inclined surface of the upper protective cover 4 to the inside of the buffer bucket 5, a buffer bucket 5 is fixedly connected to the center of the crushing wall body 1, when the ore enters the buffer bucket 5, it can move along the inclined surface of the buffer bucket 5 to the inside of the fixed cone 2 for crushing.

[0035] Reference Figure 3-Figure 5 A mounting plate 6 is provided inside the buffer bucket 5, and a connecting rod 7 is fixedly connected to the outside of the mounting plate 6. The end of the connecting rod 7 away from the mounting plate 6 is fixedly connected to the inner wall of the buffer bucket 5. The mounting plate 6 is fixedly connected to the inside of the buffer bucket 5 by the connecting rod 7, providing support for the lower protective cover 8 provided above. A lower protective cover 8 is provided above the mounting plate 6. The lower protective cover 8 is located directly above the moving cone body 3. The lower protective cover 8 can protect the top of the moving cone body 3 to prevent the ore from falling directly and colliding with the moving cone body 3, damaging the surface of the moving cone body 3, and having a good protective effect.

[0036] A buffer unit is provided at the bottom of the lower protective cover 8, and the buffer unit includes a telescopic rod 81, which is fixedly connected to the upper surface of the mounting plate 6. When the lower protective cover 8 moves downward, the telescopic rod 81 can be squeezed to compress the telescopic rod 81. A spring 82 is provided inside the telescopic rod 81. When the telescopic rod 81 is compressed, the spring 82 can be squeezed to compress the spring 82 to generate elastic potential energy, thereby buffering and slowing down the downward movement of the lower protective cover 8. A groove 83 is provided on the bottom surface of the lower protective cover 8, and the upper end of the telescopic rod 81 is fixedly connected to the inner top surface of the groove 83. The groove 83 provided can reduce the thickness of the gap between the lower protective cover 8 and the mounting plate 6 after the buffer unit is set.

[0037] When the ore falls downward to the top of the lower protective cover 8, the lower protective cover 8 can protect the top of the moving cone body 3 and directly fall and collide with the moving cone body 3. At the same time, when the moving cone body 3 is hit by the ore, the moving cone body 3 will move downward, thereby squeezing the telescopic rod 81 and the spring 82, so that the spring 82 is compressed to generate elastic potential energy. The elastic potential energy generated by the spring 82 can buffer and offset the impact force exerted on the lower protective cover 8, avoiding direct hard contact between the ore and the lower protective cover 8, which affects the service life of the lower protective cover 8. The top of the lower protective cover 8 is arranged in a circular arc structure. When the ore falls to the top of the lower protective cover 8, it can slide down along the arc surface of the top of the lower protective cover 8.

[0038] A buffer rod 9 is fixedly connected to the outer side of the lower protective cover 8, and the connecting rod 7 is located directly below the buffer rod 9. The buffer rod 9 is set to increase the buffer range of the lower protective cover 8 and prevent ore from falling directly and hitting the connecting rod 7, which affects the service life of the connecting rod 7 and the mounting plate 6. A limiting groove 10 is provided on the inner wall surface of the buffer bucket 5, and the end of the buffer rod 9 away from the lower protective cover 8 is located inside the limiting groove 10. The end of the buffer rod 9 can be accommodated and protected by the setting of the limiting groove 10 to avoid the presence of a gap between the buffer rod 9 and the inner wall of the buffer bucket 5, which may easily cause gravel to be stuck in the gap and unable to fall, and affect the buffering effect of the lower protective cover 8.

[0039] Reference Figure 6-Figure 7The inner wall surface of the buffer bucket 5 is fixedly connected with a baffle 11, which is located just above the limit groove 10. The baffle 11 can shield and protect the upper part of the limit groove 10 to prevent gravel from entering the limit groove 10 and affecting the movement of the buffer rod 9. A protective plate 12 is provided at the bottom of the mounting plate 6. The upper surface of the protective plate 12 is fixedly connected with a side plate 13. The upper end of the side plate 13 is fixedly connected to the bottom surface of the lower protective cover 8. The side plate 13 can protect the outside of the gap between the mounting plate 6 and the lower protective cover 8 to reduce the situation where gravel enters the gap and prevents debris from getting stuck in the gap and affecting the movement and buffering of the lower protective cover 8. The protective plate 12 can protect the bottom of the mounting plate 6 to prevent gravel from splashing and getting stuck in the gap between the side plate 13 and the mounting plate 6.

[0040] Working principle: add ore from above into the crushing wall body 1, and the upper protective cover 4 can provide preliminary buffering for the ore's fall. Then the ore will fall into the buffer bucket 5 and slide along the inclined surface of the buffer bucket 5 into the fixed cone 2 for crushing. When the ore enters the buffer bucket 5, if it falls above the lower protective cover 8, it will be blocked by the lower protective cover 8 to prevent the ore from falling directly and colliding with the moving cone body 3, damaging the surface of the moving cone body 3, and playing a good protective effect. At the same time, when the ore collides with the lower protective cover When the cover 8 comes into contact, it will squeeze the lower protective cover 8 downward, thereby squeezing the telescopic rod 81 and the spring 82, causing the spring 82 to compress and generate elastic potential energy. The elastic potential energy generated by the spring 82 buffers and offsets the impact force on the lower protective cover 8. The ore directly and hard contacts the lower protective cover 8, which affects the service life of the lower protective cover 8. The buffer rod 9 provided can provide buffering protection for the top of the connecting rod 7 to prevent the ore from directly falling onto the connecting rod 7, thereby affecting the service life of the connecting rod 7, the mounting plate 6 and the buffer unit.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
