Small-scale reciprocating-type balanced inertia harvester for pasture grass and harvesting method of harvester

Abstract

The invention discloses a small-scale reciprocating-type balanced inertia harvester for pasture grass. The harvester comprises a plow-type vehicle frame assembly, a power device, a transmission deviceand a cutting device; and the upper end of the plow-type vehicle frame assembly is provided with left and right handles, vehicle wheels are symmetrically installed on two sides of the lower end of the plow-type vehicle frame assembly through an axle, a supporting platform for installing the power device extends the part, located below the curved part of the plow-type vehicle frame assembly, alonga forward direction, the cutting device and the transmission device are respectively installed on the front and rear sides of the power device, the transmission device is fixedly installed between the power device and the plow-type vehicle frame assembly, the transmission device is in drive connection with the power device, and the transmission device is in drive connection with the cutting device. The harvester disclosed by the invention has strong flexibility of integral construction, and adopts linear reciprocating movement of blades converted by revolving movement of symmetrical double crank connection rods; and two blades simultaneously perform linear reciprocating movement with opposite directions to effectively balance inertial vibration generated in the cutting process, so that abreaking rate is reduced, and re-growth of the pasture grass is facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural harvesting machinery, in particular to a small reciprocating balance inertia pasture harvester and a harvesting method thereof. Background technique [0002] At present, the domestic forage harvesting machines are mainly large and small reciprocating harvesters suitable for large areas of plains. Because of their large repeated inertial force, and with the increase of cutting speed, the inertial force continues to increase, resulting in large working vibration. When cutting, The stalks will tilt and wobble, causing damage to forage species with hard stalks and brittle stalks, and for thick stalked crops, it is difficult to achieve a single cut due to vibration, resulting in long cutting times and multiple stalk occurrences If there is no cutting phenomenon, the stubble cutting will be irregular, and it is only suitable for cutting thin stalk crops. In addition, the forage harvesters in forei...

Problems solved by technology

Of course, there are also a small number of small disc forage harvesters in China at present, but the disc cutter is easy to make the forage fall back. Because the forage cutting is brittle, the small disc forage harvesters also have breakage during the cutting process. head phenomenon, which affects pasture regrowth
