Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a dustproof diesel engine cylinder cover. Background Art

[0002] The engine cylinder head is installed on the top of the cylinder body, sealing the cylinder from the top and forming a combustion chamber. It is often in contact with high-temperature and high-pressure combustion gas, so it is subject to great thermal and mechanical loads. The Chinese utility model patent, authorization announcement number "CN219197483 U", discloses a dustproof engine cylinder head, including a cylinder body and an engine cylinder head. The engine cylinder head is fixedly installed on the top of the cylinder body, and also includes a dustproof component for improving the dustproof effect of the engine cylinder head. The dustproof component is arranged below the sides of the engine cylinder head, and the dustproof component is located around the connection between the engine cylinder head and the cylinder body, which can effectively prevent dust from invading through the gap between the connected cylinder body and the engine cylinder head, thereby achieving a better dustproof effect. The structure design is simple and the operation is convenient, and there is no need to occupy more space on the surface of the engine cylinder head and the space above the engine cylinder head.

[0003] The above-mentioned technical scheme can effectively prevent dust from invading through the gap between the connected cylinder block and the engine cylinder head by setting up the coordinated use of the cylinder block, the engine cylinder head and the dustproof component, thereby achieving a better dustproof effect. The structural design is simple and the operation is convenient. It does not need to occupy more space on the surface of the engine cylinder head and the space above the engine cylinder head. However, the above-mentioned technical scheme still has certain defects. For example, the tops of the four right-angle bent plates of the above-mentioned equipment are respectively fixedly installed on the four sides of the engine cylinder head, and the four right-angle bent plates are located on the same horizontal plane. However, when the dustproof component is worn out after long-term use and needs to be maintained and repaired, the staff needs to use tools to remove the bolts one by one and then remove the dustproof component. This increases the workload of the staff and reduces the maintenance and repair efficiency of the dustproof component. Utility Model Content

[0035] See also Figure 1-3 , the utility model provides a technical solution: a dustproof diesel engine cylinder head, comprising a cylinder body 1;

[0036] The cylinder body 1 is provided with a limit device to realize quick disassembly and installation;

The insides of the two first limiting block grooves 10 are slidably connected to limiting blocks 9. The dust cover 7 is frame-shaped. The outer walls on the four sides of the cylinder head 6 are slidably connected to the inner wall of the dust cover 7. Second limiting block grooves 15 are provided on both sides of the inner wall of the dust cover 7. One end of the two limiting blocks 9 close to the second limiting block grooves 15 is in contact with the inner wall of the corresponding second limiting block grooves 15 respectively. A plurality of return springs 8 are arranged inside the two first limiting block grooves 10. A sealing ring groove 12 is provided on the inner wall of the dust cover 7. A sealing ring 11 is installed inside the sealing ring groove 12, and push block grooves 3 are provided on the outer walls on both sides of the dust cover 7. The interiors of the two push block grooves 3 are respectively communicated with the interiors of the corresponding second limit block grooves 15, and the two ends of the multiple reset springs 8 are respectively fixedly connected to the outer wall of one end of the corresponding limit block 9 and the inner wall of the first limit block groove 10.

[0038] Among them, the outer wall of the cylinder head 6 is fixedly connected to the heat sink 5, one end of the heat sink 5 close to the cylinder head 6 is fixedly extended to the inside of the cylinder head 6, the lower end outer wall of the cylinder body 1 is fixedly connected to two support seats 2, a fan 13 is installed inside the heat sink 5, and an adsorption plate 14 is fixedly connected to the inside of the heat sink 5.

[0039] Furthermore, when using the device, it is started by connecting an external power supply, and first, the cylinder body 1 is installed to the specified position through the support base 2 to realize the installation of the two-cylinder engine, and then the cylinder head 6 is installed on the cylinder body 1 and the dust cover 7 is covered at the connection between the cylinder body 1 and the cylinder head 6, and the sealing ring 11 and the connection between the cylinder body 1 and the cylinder head 6 are then increased.

This effectively dissipates the heat of the parts inside the equipment, effectively improves the service life of the parts inside the equipment, and improves the practicality of the equipment.

[0042] Working principle: first, the cylinder body 1 is installed to the specified position through the support base 2 to realize the installation of the two-cylinder engine, and then the cylinder head 6 is installed on the cylinder body 1 and the dust cover 7 is covered on the connection between the cylinder body 1 and the cylinder head 6.

The cold air enters the interior of the equipment after being processed by the adsorption plate 14 to dissipate the heat of the equipment. Then, when the dust cover needs to be removed, the push block 4 is pushed to move in the opposite direction to drive the limit block 9 to move in the opposite direction and drive the return spring 8 to contract. Then, the limit block 9 is moved in the opposite direction to make its other end disengage from the inside of the second limit block groove 15, and then the dust cover 7 can be removed from the cylinder head 6.
