Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery combine harvester technology, specifically to a cab for a combine harvester. Background Technology

[0002] In the early days, most combine harvesters only had a simple rain shelter, which could not provide the operator with a quiet and comfortable operating environment, nor could it isolate them from dust, noise, and heat. In recent years, combine harvesters with cabs have been introduced to the market, which has improved the operating environment to some extent. However, with social progress and technological development, harvester operators have increasingly higher requirements for the cab's space, visibility, comfort, and air conditioning cooling effect, and need a harvester cab with superior performance.

[0003] The main problems with existing harvester cabs are: 1. Poor sealing of the cab frame and small interior space; 2. Poor visibility, affecting observation of harvester operation; 3. Unreasonable control layout and poor human-machine interaction experience; 4. The air conditioning condenser and engine radiator share the same cooling fan, which is low and prone to blockage, affecting the air conditioning cooling effect; 5. Poor cab sealing, making it easy for dust to enter.

[0004] Chinese patent CN220830837U discloses a combine harvester cab that provides the driver with a relatively wide field of vision through a single-curved glass panel while ensuring the main body of the cab is enclosed. The condenser is positioned away from the sky for easy heat dissipation, and the rear protruding mounting section is away from the rear bulkhead to prevent heat from affecting the temperature inside the cab. The evaporator's arc-shaped top cover facilitates maintenance, and the unloading handle and combined gear lever are located on the right side of the driver's seat for easy operation. However, the forward-leaning front pillars on both sides of the single-curved glass in this design still result in some degree of obstruction of the driver's view.

[0005] Therefore, there is an urgent need for a more advanced harvester cab with advantages such as a wider field of vision, better sealing, a more reasonable control layout, and better air conditioning cooling. Summary of the Invention

[0006] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a more advanced harvester cab with advantages such as a wider field of vision, better sealing effect, more reasonable control layout, and better air conditioning cooling effect.
