Description

Technical Field

[0001] This utility model relates to the field of crushers, specifically a connecting rod type cylinder head locking mechanism for a metal crusher. Background Technology

[0002] To ensure safety during crusher maintenance or cylinder cover opening, the cylinder cover needs to be locked after opening, thus placing it in the open position for easy access to internal components. Currently, the commonly used locking structure is... Figure 5 As shown, the main method is to manually move the pin and temporarily insert it into the pin hole between the cylinder head and the base for locking. The drawback of this locking method is that it is difficult to align the pin hole properly during manual pin insertion, which increases the difficulty of pin insertion. In addition, when not in use, it is necessary to find a place to temporarily store and keep the disassembled pin, which is prone to loss. Utility Model Content

[0024] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0025] Example 1: Reference Figure 1-4 The linkage-type cylinder head locking mechanism of a metal crusher includes a crusher housing 1. A cylinder head hinge seat 16 is fixed to one side of the top of the crusher housing 1. A cylinder head 7 is hinged to the cylinder head hinge seat 16 via a cylinder head pin 5. A pin 15 for locking the position of the cylinder head 7 is provided between the tail of the cylinder head 7 and the cylinder head hinge seat 16. A connecting lug 14 is provided at the tail of the pin 15. A connecting rod 12 is hinged to the connecting lug 14. A hand-operated connecting rod 8 is hinged to the other end of the connecting rod 12. The middle part of the hand-operated connecting rod 8 is hinged between ear plates 10. The ear plates 10 are fixed to the outer wall of the cylinder head hinge seat 16. This locking mechanism is always mounted on the base of the crusher and can cooperate with the cylinder head. After the cylinder head is opened, the cylinder head is locked to the cylinder head hinge seat by manual operation using the pin, thereby achieving the purpose of locking and fixing the cylinder head and ensuring the reliability of the locking and fixing. In practical use, when it is necessary to lock the pin, the connecting rod 8 is pulled manually. Pulling the connecting rod 8 drives the connecting rod 12, which in turn drives the pin 15. The pin 15 then passes through the rear of the cylinder head 7 and the cylinder head hinge seat 16. Furthermore, a cylinder head opening mechanism is hinged between the crusher housing 1 and the cylinder head 7. This mechanism includes a cylinder body 3, which is hinged to a cylinder body hinge seat 2. The cylinder body hinge seat 2 is located on both sides of the lower part of the crusher housing 1. The end of the piston rod 4 of the cylinder body 3 is hinged to a piston rod hinge seat 6 on the cylinder head 7. This cylinder head opening mechanism can be used to control the opening and closing of the cylinder head 7. During operation, when the cylinder head needs to be opened or closed, the cylinder body 3 is activated, which drives the piston rod 4, which in turn drives the cylinder head 7. This causes the cylinder head 7 to rotate around the cylinder head pin 5, thus opening the cylinder head 7.

[0026] Furthermore, the cylinder head 7 and the cylinder head hinge seat 16 are machined with pin holes 18 for the pin 15 to pass through. The pin holes 18 can be used to cooperate with the pin 15, thereby simultaneously achieving locking and fixing between the cylinder head 7 and the cylinder head hinge seat 16.

[0027] Furthermore, the connecting rod 12 is hinged to the connecting lug 14 via the first pin 13, and the other end of the connecting rod 12 is hinged to the bottom end of the hand-operated connecting rod 8 via the second pin 11. The hand-operated connecting rod 8 is hinged to the lug plate 10 via the third pin 9. This hinged structure ensures that manually operating the hand-operated connecting rod 8 synchronously drives the connecting rod 12, which in turn drives the connecting lug 14. The connecting lug 14 then drives the pin 15, and the movement of the pin 15 synchronously locks the cylinder head 7 and the cylinder head hinge seat 16 together.

[0028] Furthermore, the hand-operated linkage 8 employs a crank arm plate. The use of a crank arm plate achieves a labor-saving effect.

[0029] Furthermore, there are two sets of connecting rods 12, symmetrically distributed on both sides of the hand-operated connecting rod 8. The symmetrical arrangement of the connecting rods 12 ensures the stability and reliability of the structure.

[0030] Furthermore, both the hand-operated connecting rod 8 and the connecting rod 12 are made of steel plate. Using steel plate simplifies the structure, reduces processing difficulty, and lowers costs.

[0031] The working process and principle of this utility model: By employing the linkage-type cylinder head locking mechanism of the metal crusher of this utility model, in specific use, when it is necessary to open the cylinder head to access the internal components of the crusher, firstly, the cylinder body 3 is started, which drives the piston rod 4, which in turn drives the cylinder head 7, causing the cylinder head 7 to rotate around the cylinder head pin 5, thereby opening the cylinder head 7. After the cylinder head 7 is opened to the correct position, the connecting rod 8 is manually pulled to simultaneously drive the connecting rod 12, which in turn drives the connecting ear 14, which in turn drives the pin 15. The movement of the pin 15 enables the cylinder head 7 and the cylinder head hinge seat 16 to be locked together synchronously, ultimately achieving the locking and fixation of the cylinder head 7.
