Description

Technical Field

[0001] The utility model relates to the technical field of diesel engine case covers, in particular to a radial load-resistant diesel engine case cover for a harvester with high reliability. Background Art

[0002] A diesel engine is an engine that burns diesel to release energy. The advantages of a diesel engine are high torque and good economic performance. The working process of a diesel engine has many similarities with a gasoline engine. Each working cycle also goes through four strokes: intake, compression, power, and exhaust. However, since the fuel used in a diesel engine is diesel, its viscosity is greater than that of gasoline and it is not easy to evaporate, but its auto-ignition temperature is lower than that of gasoline.

[0003] In the prior art, Chinese patent CN219840728U discloses "a leak-proof high-sealing diesel engine case cover", which includes a diesel engine oil tank body, an oil inlet seat is installed at the top of the diesel engine oil tank body, and an oil inlet seat is installed at the top of the diesel engine oil tank body outside the oil inlet seat, a fuel tank cap is installed on the outside of the fuel inlet seat, and the inside of the fuel tank cap is provided with an internal thread, and the outside of the fuel inlet seat is provided with an external thread. This utility model drives the threaded rod to rotate under the meshing connection of the first bevel gear and the second bevel gear, and the threaded sleeve and the jack are connected under the threaded connection to complete the connection and fixation of the fuel tank cap and the oil inlet seat, and cooperates with the sealing ring, the first sealing ring, the second sealing ring and the connecting ring to cover the connection between the oil inlet seat and the fuel tank cap, effectively improving the sealing of the connection between the fuel tank cap and the oil inlet seat, effectively avoiding the leakage of diesel inside the fuel tank, causing waste of resources, and improving the practicality of the case cover, but there are still the following defects:

[0004] (1) The connection between the fuel tank cap and the fuel inlet seat is a threaded connection, which is inconvenient and does not have an anti-theft effect;

[0005] (2) Failure to protect the fuel filling port during refueling can easily allow foreign matter to enter the diesel engine, causing oil contamination and shortening the engine life.

[0006] Therefore, we have made improvements to this and proposed a high-reliability diesel engine case cover that is resistant to radial loads for harvesters. Utility Model Content

[0007] The utility model aims to overcome the above-mentioned shortcomings and provide a highly reliable radial load-resistant diesel engine case cover for a harvester, thereby ensuring the firmness and reliability of the fuel tank cover in a closed state.

[0008] The purpose of the utility model is achieved in this way:

[0009] A highly reliable radial load-resistant diesel engine case cover for a harvester, comprising a cover plate, an oil filling port is provided on the top of the cover plate, and an opening and closing mechanism used in conjunction with the oil filling port is provided on the top of the cover plate;

[0010] The opening and closing mechanism includes an oil inlet seat, a fuel tank cover, an L-shaped plate, a fixing plate, an hexagon socket bolt, a safety lock and a filter assembly. The oil inlet seat is fixedly connected to the top of the cover plate and is used in conjunction with the oil filling port. The fuel tank cover is sleeved on the top of the oil inlet seat. The L-shaped plate is fixedly connected to the side wall of the oil inlet seat. The two fixing plates are fixedly connected to the side wall of the fuel tank cover and are hinged to the L-shaped plate. The four hexagon socket bolts all penetrate the oil inlet seat to the inside of the cover plate. The four hexagon socket bolts are equidistantly distributed on the oil inlet seat. The safety lock penetrates the fuel tank cover and is used in conjunction with the oil inlet seat. The safety lock is fixedly connected to the fuel tank cover. The filter assembly is arranged inside the oil filling port and is used in conjunction with the oil inlet seat.

[0011] Furthermore, the filter assembly includes a filter screen, a limit block and a limit groove. The filter screen is arranged inside the oil filling port. The four limit blocks are fixedly connected to the side walls of the filter screen and are equidistantly distributed around the circumference. The limit groove is opened at the top of the oil inlet seat and is clamped with the limit block.

[0012] Furthermore, four positioning columns are fixedly connected to the bottom of the oil inlet seat, and the four positioning columns are equidistantly distributed in a circle at the bottom of the oil inlet seat. The top of the cover plate is provided with positioning holes that are plugged into the positioning columns.

[0013] Furthermore, a sealing gasket used in conjunction with the oil inlet seat is fixedly connected to the bottom of the fuel tank cover, and the sealing gasket is made of nitrile rubber.

[0014] Furthermore, a float is arranged inside the filter screen, and the float is made of polyethylene.

[0015] Furthermore, a protective cover is hinged on the top of the fuel tank cover and is used in conjunction with a safety lock.

[0016] Furthermore, a reflective sticker is provided on the top of the fuel tank cover.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The utility model provides a highly reliable radial load-resistant diesel engine case cover for a harvester. The oil inlet seat is aligned with the oil filling port on the top of the cover plate by an opening and closing mechanism, and then the oil inlet seat and the cover plate are locked and fixed by using hexagon socket bolts. The fuel tank cover is hinged to the L-shaped plate through a fixing plate, so that the fuel tank cover is easy to open or close, and there is no need to remove the fuel tank cover every time, which greatly improves convenience. The key is used in conjunction with the safety lock to ensure the firmness and reliability of the fuel tank cover in the closed state.

[0019] The utility model discloses a high-reliability radial load-resistant diesel engine case cover for a harvester. By arranging a filter assembly, a filter screen is clamped with a limit groove on the top of an oil inlet seat through a limit block, thereby ensuring the stability of the filter screen during installation. The filter screen can filter the engine oil injected through the oil filling port and can prevent external debris from entering the interior of the cover during the refueling process, thereby solving the problem in the prior art that the oil filling port cannot be protected during the refueling process, and external debris is easily allowed to enter the interior of the diesel engine, causing oil pollution and resulting in a shortened engine life.
