Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of silage harvesting, in particular to a silage harvester. BACKGROUND

[0002] The silage harvester is an agricultural machine for harvesting, crushing and throwing silage crops (such as corn and pasture grass), and its core components include a cutting device, a feeding system, a crushing mechanism, a throwing device, a transmission system, a cab, a chassis, a hydraulic system and an electronic control system. The cutting device is usually composed of a rotating cutter head and a moving blade, which is responsible for cutting the crop stems, and some models are equipped with a profiling device to adjust the ground clearance. The feeding system includes rollers and chains, which ensures continuous feeding by compressing and transporting the crops. The crushing mechanism adopts a hammer blade or a roller design, which cooperates with an adjustable screen to control the feed cutting length (10-30mm), directly affecting the fermentation quality. The throwing device is composed of a high-speed fan and a guide cylinder, which throws the crushed material into the transport vehicle, with a throwing distance of more than 15 meters. The transmission system distributes the engine power to each component through the gearbox, belt pulley and gear set. The engine is usually a high-power diesel engine (150-300 horsepower). The cab is equipped with a multifunctional control panel, a hydraulic control lever and a comfortable seat, and some models integrate GPS navigation and operation monitoring screen. The chassis uses heavy-duty tires or track-type running gear, which improves the field passability with a hydraulic steering system. The hydraulic system drives the feeding roller speed regulation, cutter lifting and other actions, and the electronic control system monitors the load, speed and other parameters in real time and automatically adjusts the feeding speed.

[0003] The existing silage harvester usually has a harvesting device and a material collecting device to complete the harvesting task together, but the throwing device on the harvester is usually fixed in length, which makes it difficult to control the distance between the harvester and the material transport vehicle, and thus the feed may be thrown and fall to the ground.
