Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural and farm machinery technical field especially relates to a kind of gas storage device for seeding machine. TECHNICAL BACKGROUND

[0002] In the field of agricultural machinery, the seeding machine is the core equipment to realize precision seeding and improve work efficiency. The main beam, as the core load-bearing structure of the functional modules such as the seeding unit, the seed metering device and the furrow opener, is mainly focused on the optimization of mechanical strength and spatial layout in traditional design. With the popularization of pneumatic seeding technology (such as air-suction seed metering device and pressure-driven fertilization system), the gas storage device has gradually become a key subsystem of the seeding machine. Early solutions mostly use external gas tanks or independent air pump modules, which are welded or bolted to the side of the main beam by brackets. This design leads to the expansion of the horizontal size of the whole machine, which is prone to collision and damage when turning in narrow plots or transporting on roads. In addition, the disassembly of many parts is required for inspection and maintenance of the split gas storage device, which increases the average maintenance time by 2-3 working hours, wastes a lot of time and reduces the work efficiency. SUMMARY

[0003] The utility model aims to improve the spatial layout utilization rate of the seeding machine, facilitate transportation, reduce maintenance and maintenance time, and improve work efficiency. A gas storage device for a seeding machine is characterized by comprising a seeding machine main beam, an air pipe, a connector, a one-way valve, a connecting seat, an air pump, an air pressure sensor, an electromagnetic valve, a safety valve and a tee joint. The two ends of the seeding machine main beam are closed, and the inside is a hollow cavity structure. The upper surface of the seeding machine main beam is provided with a plurality of connecting seats. The air pump is connected to any one of the connectors through the air pipe. The connector is detachably connected to any one of the connecting seats. The one-way valve is arranged between the air pipe and the air pump to prevent the backflow of the gas generated by the air pump. The air pressure sensor is detachably connected to any one of the connecting seats. One end of the tee joint is connected to the connector through the air pipe. The connector is detachably connected to the connecting seat. The other end of the tee joint is connected to the electromagnetic valve. The remaining end is connected to the components of the seeding machine through the air pipe. The safety valve is connected to any one of the connecting seats.

[0004] Preferably, the seeding machine main beam is a load-bearing structure of the seeding machine. The two ends of the seeding machine main beam are closed, and the inside is a hollow cavity structure. The gas output by the air pump is stored in the cavity of the seeding machine main beam for use by other components of the seeding machine. A drain valve is fixedly arranged on the lower surface of the seeding machine main beam to drain the condensed water generated by the compressed air of the air pump.

[0005] Preferably, during operation, the air pressure sensor can detect the pressure inside the main beam cavity of the seeder in real time. When the pressure inside the main beam cavity of the seeder exceeds the pressure value required by other components of the seeder, the solenoid valve will automatically release air. When the pressure inside the main beam cavity of the seeder does not reach the pressure value required by other components of the seeder, the air pump will automatically pressurize the main beam cavity of the seeder.

[0006] Preferably, the safety valve can control the pressure inside the upper cavity of the seeder main beam. When the pressure inside the cavity exceeds the specified pressure value that the seeder main beam can withstand, the safety valve will automatically release pressure until the pressure inside the seeder main beam cavity is less than the set safety pressure value.

[0007] The present invention achieves the following beneficial technical effects compared to the prior art:

[0008] 1. The main beam of the seeder in this utility model is the load-bearing component of the seeder itself. The seeder does not need to add an external air storage device, which saves the space of the seeder and reduces economic expenditure.

[0009] 2. This utility model provides safe, stable and reliable air pressure, ensuring that all air supply components of the seeder work smoothly, and making maintenance and repair simple and convenient, thereby improving efficiency. Attached Figure Description
