[0022] The counterweight protection device for a cone crusher according to this utility model has the following beneficial effects:

[0023] This invention firstly involves the welding rod and the mounting sleeve engaging with each other. Then, by starting a second stepper motor, the second rotating rod and the winding wheel are rotated, causing the winding wheel to wind the steel wire rope. Through the cooperation of the vertical rod and the sliding sleeve, the steel wire rope is wound, causing the limiting block to slide along the outer wall of the vertical rod through the sliding sleeve and compress the high-pressure spring body, causing deformation. This prevents the limiting block from engaging with the limiting sleeve, facilitating the installation and removal of the counterweight plate by the operator and reducing the operator's labor intensity.

[0024] This invention firstly improves the robustness of the impact-resistant plate through its design and the cooperation between the upper and lower anti-compression blocks. Furthermore, the inclusion of reinforcing ribs within the first and second impact layers enhances the impact resistance of the plate. Attached Figure Description

Detailed Implementation

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0036] Example 1: Refer to Figures 1-5This is the first embodiment of the present invention, which provides a counterweight protection device for a cone crusher. It addresses the problem that most counterweight devices on the market consist of a counterweight body and a counterweight cover. However, during use, the crushed ore impacts the surface of the counterweight cover, causing dents after prolonged impact. Furthermore, replacing the counterweight device is inconvenient for operators, increasing their workload. The device includes the cone crusher outer shell 1, and the cone crusher... A support column 2 is installed at the top of the outer shell 1, and a drive rod 3 is rotatably installed at the middle position inside the support column 2. A counterweight cone crusher assembly 4 is installed at the bottom of the drive rod 3, and a fixing rod 6 is installed at the bottom of the counterweight cone crusher assembly 4. A fixing seat 5 is installed on the inner wall of the cone crusher outer shell 1. A rotating table 7 is rotatably installed inside the fixing seat 5 through a bearing, and a cone-shaped tooth block body 701 is installed at the bottom of the rotating table 7. A discharge pipe 702 is installed on the inner wall of the rotating table 7. A counterweight assembly 8 is provided on the inner wall of the cone crusher outer shell 1.

[0037] An installation box 501 is installed on the outer wall of the cone crusher shell body 1, and a first stepper motor 502 is installed on the side wall of one end of the installation box 501. A first rotating rod 503 is installed at the output end of the first stepper motor 502, penetrating the interior of the cone crusher shell body 1. A bevel gear body 504 is installed at one end of the first rotating rod 503. The bevel gear body 504 meshes with the bevel gear block body 701. An installation sleeve 101 is installed on the outer wall of the cone crusher shell body 1. A limit sleeve 102 is installed at the top and bottom of the installation sleeve 101. The installation sleeve 101 cooperates with the welding rod 802 to allow the counterweight plate 801 to be installed and removed from the installation sleeve 101 via the welding rod 802.

[0038] The counterweight assembly 8 includes a counterweight plate 801, an impact-resistant plate 8012 installed on the outer wall of the counterweight plate 801, a welding rod 802 installed at one end of the counterweight plate 801, and the welding rod 802 cooperates with the mounting sleeve 101. The welding rod 802 has an installation chamber 8021 inside, and vertical rods 803 are installed at the top and bottom of the installation chamber 8021. A sliding sleeve 804 is fitted on the outer wall of the vertical rod 803, and a limiting block 805 penetrating the welding rod 802 is installed at one end of the sliding sleeve 804. The limiting block 805 cooperates with the limiting sleeve 102. Through the cooperation of the sliding sleeve 804 and the vertical rod 803, the limiting block 805 can drive the sliding sleeve 804 to slide on the outer wall of the vertical rod 803.

[0039] A high-pressure spring body 806 is installed at one end of the limit blocks 805 that are close to each other. A steel wire rope 8011 is installed at one end of the limit blocks 805 that are close to each other. Through the design of the high-pressure spring body 806, the steel wire rope 8011 is pulled to drive the limit blocks 805 to slide and squeeze the high-pressure spring body 806 to deform.

[0040] A second stepper motor 807 is installed on one side wall inside the installation chamber 8021, and a second rotating rod 808 is installed on the output end of the second stepper motor 807. A winding wheel 809 is installed on the outer wall of the second rotating rod 808, and the inside of the winding wheel 809 is fixedly connected to the wire rope 8011. Guide wheels 8010 are installed on the side walls of the installation chamber 8021. By starting the second stepper motor 807, the second rotating rod 808 is driven to rotate, which in turn drives the winding wheel 809 to rotate, so that the winding wheel 809 can rotate to wind the wire rope 8011.

[0041] The specific working principle is as follows: when the counterweight assembly 8 needs to be installed and disassembled, the new type first engages with the installation sleeve 101 through the welding rod 802, and drives the second rotating rod 808 and the winding wheel 809 to rotate by starting the second stepper motor 807. The winding wheel 809 rotates to wind the wire rope 8011. Through the cooperation of the vertical rod 803 and the sliding sleeve 804, the wire rope 8011 is wound, which drives the limiting block 805 to slide on the outer wall of the vertical rod 803 through the sliding sleeve 804 and squeeze the high-pressure spring body 806 to deform. This makes the limiting block 805 no longer engage with the limiting sleeve 102, which makes it easier for the operator to install and disassemble the counterweight plate 801, thereby reducing the labor intensity of the operator.

[0042] Example 2: Refer to Figures 1-5This is the first embodiment of the present invention, which provides a counterweight protection device for a cone crusher. Most counterweight devices on the market consist of a counterweight body and a counterweight cover. However, during use, the crushed ore impacts the surface of the counterweight cover, causing dents after prolonged impact. Furthermore, replacing the counterweight device is inconvenient for operators, increasing their workload. The impact-resistant plate 8012 includes a first reinforcing layer 80121. The bottom of 0121 is provided with an impact-resistant layer 80122, and the top and bottom of the impact-resistant layer 80122 are both equipped with an upper pressure-resistant block 80123 and a lower pressure-resistant block 80124. The upper pressure-resistant block 80123 and the lower pressure-resistant block 80124 cooperate with each other. The bottom of the impact-resistant layer 80122 is provided with a first impact layer 80125, and the bottom of the first impact layer 80125 is provided with a second impact layer 80126. The interior of the second impact layer 80126 and the first impact layer 80125 is filled with reinforcing ribs, thereby improving the firmness of the impact-resistant plate 8012.

[0043] The specific working principle is as follows: First, through the design of the impact-resistant plate 8012, and through the cooperation of the upper anti-compression block 80123 and the lower anti-compression block 80124, the impact-resistant plate 8012 is made more robust. At the same time, the first impact layer 80125 and the second impact layer 80126 are filled with reinforcing ribs, thereby improving the impact resistance of the impact-resistant plate 8012.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
