Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery equipment technology, specifically to an air compressor and a harvester using the air compressor. Background Technology

[0002] Air compressors are fundamental products in the machinery industry, widely used across various sectors. Traditional air compressors convert the rotational mechanical energy output from a drive unit (electric motor or diesel engine) into the pressure energy of gas. They are the core equipment providing power to pneumatic systems (or pneumatic purging points). However, when used in agricultural machinery, such as using an electric motor as the power source for the air compressor, the electric motor typically uses a voltage higher than the human safety voltage of 36V. Harvesters operate in complex environments (mostly metal, with high moisture content in crops during operation), posing a significant risk of electric shock to operators. If a diesel engine is used as the power source for the air compressor, firstly, diesel engines require a large space, making design and layout difficult; secondly, diesel engines require fuel, increasing costs. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an air compressor and a harvester using the air compressor. A hydraulic motor is used in conjunction with the engine on the harvester as the power source for the compressor, thus replacing conventional electric motors or diesel engines. This design offers advantages such as simple structure, small footprint, and high safety.

[0005] As a further improvement to the above technical solution:

[0006] The transmission device includes a transmission shaft, a pulley one is provided at the end of the transmission shaft, a pulley two is provided at the drive end of the compressor main unit, and a transmission belt is provided between the pulley one and the pulley two.

[0007] The transmission device is provided with a protective mesh frame on its exterior, and a bracket connected to the protective mesh frame is provided on one side of the mounting base.

[0008] The upper part of the mounting base is provided with a base for mounting a hydraulic motor, and one end of the base is provided with a positioning plate, and the positioning plate is provided with a bearing seat for mounting a drive shaft.

[0009] The pressure detection module includes a pressure sensor switching valve connected to the storage gas cylinder, and a control valve electrically connected to the pressure sensor switching valve is disposed above the hydraulic motor.

[0010] A harvester includes a harvester body, wherein a gas compression module is provided on the harvester body, and the gas compression module includes any one of the air compressors described in 1-5 above.

[0011] The beneficial effects of this utility model embodiment are as follows: The air compressor includes a storage gas cylinder, a mounting base is provided above the storage gas cylinder, a compressor main unit is provided at one end of the mounting base, and a drive module is provided at the other end.

[0016] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] like Figure 1As shown, the air compressor in this embodiment includes a storage cylinder 1, a mounting base 2 on top of the storage cylinder 1, and a base plate 2. The lower surface of the base plate is connected to the storage cylinder 1. The base plate is used to mount the compressor host 3 and the drive module, making the entire device modular. This facilitates later maintenance and parts replacement when dealing with complex operating scenarios. One end of the mounting base 2 is equipped with the compressor host 3, and the other end is equipped with the drive module. The output end of the compressor host 3 is equipped with an air supply pipe 4 that provides compressed gas to the storage cylinder 4. The storage cylinder 1 is equipped with a pressure detection module. The drive module includes a hydraulic motor 5 that is linked to the engine of the harvester. The output end of the hydraulic motor 5 is equipped with a transmission device connected to the compressor host 3. The harvester's engine provides operating power to the hydraulic motor 5, eliminating the need for additional electric motors or diesel engines. This makes the entire device more compact and saves space. At the same time, using a hydraulic motor instead of an electric motor for operation can avoid the occurrence of electric shock when working in complex environments.

[0018] like Figure 2 As shown, the transmission device includes a transmission shaft 6, with a pulley 7 at one end of the transmission shaft 6 and a pulley 8 at the drive end of the compressor main unit 3. A transmission belt 9 is provided between the pulley 7 and the pulley 8. The belt drive structure is simple and easy to install and maintain.

[0019] The transmission device is provided with a protective mesh frame 10 on the outside. The mounting base 2 is provided with a bracket 11 connected to the protective mesh frame 10 on one side. The function of the protective mesh frame 10 is to prevent impurities or straw from getting tangled during the operation of the harvester, which would lead to a decrease in transmission efficiency or damage to the equipment.

[0020] like Figure 3 As shown, the upper part of the mounting base 2 is provided with a base 12 for mounting the hydraulic motor 5. The base 12 is detachably connected to the base plate. One end of the base 12 is provided with a positioning plate 13 located between the protective mesh frame 10 and the hydraulic motor 5. The positioning plate 13 is provided with a bearing seat 14 for mounting the drive shaft 6 to ensure the stability of the drive shaft 6 during operation.

[0021] The pressure detection module includes a pressure sensor switch valve 15 connected to the storage gas cylinder 1. A control valve 16 electrically connected to the pressure sensor switch valve 15 is installed above the hydraulic motor 5. After the compressor host 3 delivers gas into the storage gas cylinder 1, the pressure inside the cylinder rises. When the pressure rises to the set value of 0.8 MPa of the pressure sensor switch valve 15, a signal is sent to the control console. After receiving the signal, the control console sends a stop operation signal to the control valve 16. At this time, the hydraulic motor stops operating, and the compressor host 3 stops.

[0022] The harvester of this embodiment includes a harvester body, on which a gas compression module is provided, and the gas compression module includes the air compressor mentioned above.
