Description

Technical Field

[0001] The utility model relates to the technical field of cone crushers, and particularly relates to a crusher air vent for a cone crusher. Background Art

[0002] A cone crusher is a kind of crushing machinery suitable for raw materials in the metallurgical, construction, road-building, chemical and silicate industries. According to different crushing principles and different particle sizes of products, it is divided into many models. The crusher is widely used in many departments such as mines, smelting, building materials, highways, railways, water conservancy and chemical industries. The air vent is a device responsible for ventilation. The function of the air vent is to exchange the air inside and outside the box body, so that the air pressure inside and outside the box body is balanced, prevent the box body from exploding due to excessive air pressure, and at the same time can prevent moisture and mildew.

[0003] When a cone crusher is in use, an air vent is needed to introduce air into the crushing cavity and exchange the air inside the box body with the air outside the box body to balance the air pressure inside and outside the box body. However, during the process of exchanging air by the air vent, dust in the air will adhere to the inner wall of the air vent with use. Over time, too much dust accumulates, resulting in more dust in the air introduced into the crushing cavity. Too much dust entering the sealed bearing will cause wear of the sealed bearing. Summary of the Utility Model

[0004] The utility model provides a crusher air vent for a cone crusher, which solves the problem that when the air vent of the existing cone crusher is used for too long, dust will accumulate on the inner wall of the air vent. Too much dust accumulation will cause dust to be brought into the crushing cavity when air is inhaled, and too much dust entering the sealed bearing will cause wear of the sealed bearing.

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0038] Such as Figures 1 to 4As shown in the figure, this embodiment proposes a crusher breather for a cone crusher, which includes a crusher body 1, and also includes a support plate 2, a support seat 3, an installation cylinder 4, a blowing mechanism, a blowing blade 5 and a sliding cleaning mechanism. The support plate 2 is fixedly connected to the bottom end of the crusher body 1. The support seat 3 is fixedly connected to the support plate 2. The installation cylinder 4 is fixedly connected to the support seat 3. The blowing mechanism is installed in the installation cylinder 4. The blowing blade 5 is located in the installation cylinder 4. The sliding cleaning mechanism is installed on the installation plate 6. When the breather works, the blowing mechanism works to make the blowing blade 5 rotate, so as to exchange air inside and outside the crushing cavity. Cooperating with the sliding cleaning mechanism, while the blowing blade 5 rotates, it reciprocally slides in the installation cylinder 4, avoiding dust from being adsorbed in the installation cylinder 4 and being blown into the crusher together with the air flow, causing wear to the sealed bearing of the crusher. The installation cylinder 4 can be detachably installed on the outer wall of the crusher body 1, which is convenient for disassembly and cleaning after long-term use.

[0039] Among them, the blowing mechanism includes an installation plate 6, a smooth rod 7 and a driving component. The installation plate 6 is fixedly connected to the support plate 2. One end of the smooth rod 7 is rotatably connected in the installation cylinder 4, and the other end of the smooth rod 7 is rotatably connected to the installation plate 6. The blowing blade 5 is slidably connected to the smooth rod 7 through a limiting rod 15. The driving component is installed on the installation plate 6. When the blowing mechanism works, the driving component drives the smooth rod 7 to rotate, so that the blowing blade 5 rotates and sends air flow into the crushing cavity. The blowing blade 5 can rotate in the reverse direction under the action of the reverse rotation of the motor 11, so that the internal air flow flows out, stirring the air flow to achieve the purpose of air flow exchange.

[0040] Secondly, the sliding cleaning mechanism includes an internal thread 16, a slider 8 and a cleaning block 10. The internal thread 16 is opened on the inner wall of the installation cylinder 4. There are multiple sliders 8. Each blade of the blowing blade 5 is fixedly connected with a slider 8. The slider 8 cooperates with the internal thread 16. The cleaning block 10 is fixedly connected to the outer wall of the slider 8. When the sliding cleaning mechanism works, at this time the motor 11 is in a working state. The motor 11 drives the smooth rod 7 to rotate, so that the blowing blade 5 rotates. At this time, the slider 8 on the blowing blade 5 slides in the internal thread 16 of the installation cylinder 4, driving the blowing blade 5 to slide along the limiting rod 15 on the smooth rod 7. When sliding to the position of the limiting ring, the motor 11 rotates in the reverse direction, so that the blowing blade 5 slides in the reverse direction while rotating, thereby completing air exchange.

[0041] Thirdly, the driving component includes a motor 11, a gear one 12 and a gear two 13. The motor 11 is fixedly connected to the installation plate 6. The gear one 12 is rotatably connected to the installation plate 6. The output end of the motor 11 is fixedly connected to the gear one 12. The gear two 13 is rotatably connected to the installation plate 6. When the driving component works, first the motor 11 starts, driving the gear one 12 to rotate. The gear one 12 cooperates with the gear two 13, thereby driving the gear two 13 to rotate. The gear two 13 drives the smooth rod 7 fixedly connected thereto to rotate, driving the blowing blade 5 to rotate, realizing the driving function.

[0042] Among them, both the second gear 13 and the mounting plate 6 are provided in a hollow shape, which is beneficial to a large amount of air being sucked into the mounting cylinder 4 through the second gear 13 and the mounting plate 6 as the air supply blade 5 rotates.

[0043] Finally, a limit ring is provided at one end of the polished rod 7 rotatably connected to the mounting cylinder 4. When the air supply blade 5 slides to the position of the limit ring, the motor 11 reverses to prevent the air supply blade 5 from bumping against the mounting cylinder 4 and causing damage to the air supply blade 5.

[0044] In this embodiment, when the air vent works, first the motor 11 is started to drive the first gear 12 to rotate, thereby driving the second gear 13 to rotate, further driving the optical axis to rotate, and the air supply blade 5 on the optical axis rotates accordingly under the action of the limit rod 15. While the air supply blade 5 is rotating, the slider 8 on the air supply blade 5 slides in the internal thread 16 on the inner wall of the mounting cylinder 4, driving the air supply blade 5 to slide on the optical axis while rotating. At this time, the cleaning block 10 moves in the internal thread 16 while continuously sliding and cleaning the inner wall of the mounting cylinder 4.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
