Description

TECHNICAL FIELD

[0001] The utility model relates to a sealing structure of a harvesting machine openable and closable dust cover. BACKGROUND

[0002] With the continuous development of agricultural mechanization, large agricultural machinery such as harvesters are widely used in agricultural production. During the operation of the harvester, due to the complex working environment, it often faces the invasion of dust, debris and other external factors. These factors not only may damage the function of the internal sensitive components, but also may cause the efficiency of the heat dissipation system to decrease, thereby affecting the stability and long-term service life of the equipment.

[0003] The radiator and oil cooler in the harvester are one of the key components for maintaining the working temperature of the engine and hydraulic system and ensuring their normal operation. The radiator is usually exposed to the external environment and is easily attacked by dust, mud and other debris, causing blockage. This not only affects the heat dissipation effect of the radiator and oil cooler, but also may cause overheating of the equipment and trigger a failure. In addition, the sealing of the radiator and other key components such as hydraulic lines also needs to be ensured to prevent external substances from penetrating and causing damage to the lines or system failure.

[0004] In order to solve the above problems, various dust cover designs have been proposed in the prior art, mainly by adding dust covers, sealing strips and other measures to prevent external debris from entering the equipment. However, the existing dust covers often have certain limitations. For example, the opening and closing structure and sealing design of the dust cover are not perfect enough, which may result in poor sealing effect when the dust cover is closed, and debris can still enter the radiator through the gap, thereby affecting the heat dissipation effect of the equipment. In addition, the hydraulic lines may be crushed due to too large an angle during opening and closing, affecting the normal operation of the hydraulic system.

[0005] Therefore, how to design a dust cover sealing structure that can effectively seal and prevent debris from entering without affecting the normal operation of the hydraulic lines has become a major challenge in the current technology. The dust cover structure not only needs to have good sealing performance, but also needs to consider the convenience of opening and closing the equipment, the stability of the hydraulic lines, and the heat dissipation performance of the radiator.

[0006] The utility model discloses a novel dust cover sealing structure aiming at the above problems, which aims to solve the problems of poor sealing of the dust cover, damage to the hydraulic lines and other problems in the prior art through an innovative design scheme, thereby improving the working efficiency and service life of the equipment, and having important technical value and application prospect. CONTENT OF THE UTILITY MODEL

[0007] The utility model discloses a novel dust cover sealing structure aiming at the above problems, which aims to solve the problems of poor sealing of the dust cover, damage to the hydraulic lines and other problems in the prior art through an innovative design scheme, thereby improving the working efficiency and service life of the equipment, and having important technical value and application prospect.

[0008] A sealing structure for an openable and closable dust cover for a harvester includes:

[0009] A dust cover has an outer shell structure for protecting internal components and preventing debris from entering. The dust cover can be opened and closed by an opening and closing mechanism, and the outer shell of the dust cover has an inner cutout for accommodating a support plate. The inner cutout of the outer shell of the dust cover is arc-shaped.

[0010] The radiator is fixedly mounted on the chassis for heat dissipation and is in contact with the outer shell of the dust cover. When the dust cover is closed, it forms a sealed connection with the radiator.

[0011] Oil cooler: Installed inside a dust cover and connected to the hydraulic lines, it is used for heat dissipation of the hydraulic system;

[0012] A support plate is fixedly connected to the radiator and contacts the inside of the dust cover when the dust cover is opened and closed. The support plate is provided with clearance holes for hydraulic lines to pass through. The support plate and the dust cover form a sealed connection to prevent debris from entering the radiator and oil cooler.

[0013] Furthermore, the support plate is arc-shaped, and the arc-shaped support plate matches the arc-shaped cutout of the dust cover.

[0014] Furthermore, the sealing sponge is located between the inner cut of the dust cover and the outer side of the support plate.

[0015] Furthermore, the radiator is fixedly connected to the support plate by at least two bolts.

[0016] Furthermore, the hydraulic pipeline includes hydraulic pipeline one and hydraulic pipeline two, which are connected to each other. Hydraulic pipeline one is located inside the dust cover, and hydraulic pipeline two is fixedly installed on the outside of the dust cover.

[0017] Furthermore, the opening and closing mechanism is a structure in which the radiator and the dust cover are hinged together.

[0018] Furthermore, one end of the first hydraulic line is provided with a rubber hose and connected to the oil cooler, and a fixed oil pipe is provided on the support plate. The first hydraulic line and the second hydraulic line are connected through the fixed oil pipe.

[0019] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0020] The design of this utility model features an openable dust cover. Through the setting of a support plate, the hydraulic oil pipe connected to the oil cooler passes through the support plate and connects to the outside. The oil pipe moves as the dust cover opens and closes, and the movement trajectory of the oil pipe is restricted by the support plate, thereby optimizing its movement trajectory and ensuring that the oil pipe will not be crushed. At the same time, the arc-shaped plate and the dust cover seal the seal, ensuring a good sealing effect.

[0021] The precise, rounded cut and the fit between the cut and the support plate create an excellent seal, effectively preventing external debris from entering the dust cover. This not only ensures the cleanliness of the radiator and oil cooler interior but also prevents debris from clogging the radiator's cooling channels, thus guaranteeing the efficient operation of the cooling system.

[0022] By rationally designing the layout of the hydraulic pipelines and the opening angle of the dust cover, uneven stress and compression of the hydraulic pipelines caused by excessively large opening angles of the dust cover are avoided. This effectively ensures the stability of the hydraulic pipelines and the working efficiency of the hydraulic system, preventing hydraulic system failures caused by pipeline compression.

[0023] The dust cover of this invention greatly improves the space for cleaning and maintenance. This design allows maintenance personnel to more easily perform equipment inspection, cleaning, and maintenance, improving the maintainability and ease of operation of the equipment.

[0024] Compared to traditional rectangular structures, the combination of an arc-shaped inner notch and a support plate results in a smaller sealing gap and a better sealing effect. Furthermore, the arc-shaped design, compared to a right-angle design, not only reduces friction but also offers better aesthetics, making the entire structure more harmonious and modern.

[0025] This utility model features a simple structural design, precise fit, and easy assembly. The radiator and support plate are fixedly connected by bolts, which not only improves installation efficiency but also reduces errors or operational difficulties caused by complex assembly. This design makes production and maintenance more efficient and cost-effective.

[0026] In summary, the dust cover sealing structure of this utility model exhibits significant advantages in dust prevention, sealing, ease of maintenance, and hydraulic system protection, making it an innovative and practical solution. Attached Figure Description

[0031] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0032] This embodiment uses a harvester as an example to specifically introduce the implementation method of the dust cover sealing structure.

[0033] First, the dust cover 1 is made of a metal shell material, with an arc-shaped inner cutout for mounting the support plate 6. The dust cover 1 can be opened and closed via a hinge mechanism with the radiator 2, making operation simple and convenient. The arc-shaped design of the inner cutout allows the support plate 6 to be securely fixed to the dust cover 1 while maintaining a tight seal.

[0034] The radiator 2 is fixedly mounted on the harvester chassis, positioned in the area that contacts the outer shell of the dust cover 1. The surface of the radiator 2 has a number of cooling fins, effectively increasing the heat dissipation area and ensuring the equipment's cooling requirements. When the dust cover 1 is closed, its outer shell fits tightly against the radiator 2, forming a good seal and preventing dust, dirt, and other debris from adhering to the surface of the radiator 2, which could cause the engine to overheat.

[0035] The support plate 6 is arc-shaped, matching the inner cutout shape of the dust cover 1, allowing for precise contact and sealing with the dust cover 1. The support plate 6 has channels for supporting hydraulic lines. Hydraulic line 4 is fixedly installed on the inner side of the support plate 6, while hydraulic line 5 is externally fixedly connected to ensure the stability of the hydraulic system.

[0036] The oil cooler is installed inside the dust cover and is used for cooling the hydraulic system. The radiator is installed on the harvester chassis and is used for cooling the engine. The opening and closing mechanism of the protective cover is to facilitate cleaning the dust adhering to the surface of the oil cooler and radiator.

[0037] To further enhance the sealing performance, a sealing sponge 7 is embedded between the inner slit of the dust cover 1 and the contact surface of the support plate 6. This sponge material has good elasticity and abrasion resistance, and when the dust cover 1 is closed, it can fit tightly with the support plate 6 to prevent the penetration of debris and ensure the cleanliness of the internal environment.

[0038] The radiator 2 and the support plate 6 are secured with two bolts. The bolts are made of corrosion-resistant steel, ensuring a stable connection during long-term operation and preventing loosening due to external forces or vibrations. This bolted connection maintains a stable seal between the dust cover 1 and the support plate 6 during opening and closing, reducing the risk of air leakage or debris ingress.

[0039] The opening and closing mechanism adopts a hinge structure between the radiator 2 and the dust cover 1, which allows the dust cover 1 to be opened or closed easily. When equipment maintenance or inspection is required, the operator can easily access the radiator 2 and hydraulic lines 4 and 5 simply by opening the dust cover 1.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
