Embodiment Construction

[0019] The technical solutions of the present invention will be further described below through the drawings and embodiments.

[0020] Such as figure 1 As shown, the hydraulic excavator forage harvesting device of the present invention includes an excavator arm 1, an excavator bucket cylinder 2, an excavator rocker 3, an excavator connecting rod 4, a main frame 5, a tilting mechanism 6, Grass holding mechanism 7, cutting mechanism 8, shunt frame 9 and protective cover 10. The tipping mechanism 6, the grass holding mechanism 7, the cutting mechanism 8, the shunt frame 9 and the protective cover 10 are installed on the main frame 5 to form a forage harvesting device. The forage harvesting device is connected to the bucket arm 1 of the excavator through the tipping mechanism 6 It is hinged to the connecting rod 4 of the excavator to realize the connection between the forage harvesting device and the excavator, and the bucket cylinder 2 of the excavator is driven to adjust the postur...

Abstract

Provided is a hydraulic excavator pasture harvesting device. A tilting mechanism of the device comprises a base body and a tilting hydraulic oil cylinder. A grass embracing mechanism comprises a right grabhook, a grass embracing hydraulic oil cylinder, a pulling rod and a left grabhook. A cutting mechanism comprises a hydraulic motor, a driving belt wheel, a belt, a mounting cylinder, a driven belt wheel, a main shaft, a bearing, a mounting screw, a cutting disc mounting base, a cutting disc and a tensioning adjusting screw. The tilting mechanism of the pasture harvesting device is hinged to a bucket rod and a connecting rod of a hydraulic excavator. The cutting mechanism achieves pasture cutting off by the cutting disc by hydraulic motor driving and belt transmission. The grass embracing mechanism achieves cut grass embracing by the grabhooks by grass embracing hydraulic oil cylinder driving and a four-connecting-rod mechanism. The tilting mechanism achieves pasture discharging by titling hydraulic oil cylinder driving. Pasture which cannot be harvested by a branching frame during harvesting are branched to the two sides. Pasture such as pennisetum hydridum can be harvested quickly, efficiently, easily and stably.

Description

Technical field [0001] The invention relates to the technical field of forage harvesting machinery, in particular to a forage harvesting device for a hydraulic excavator, which is used for harvesting forage grass such as emperor bamboo grass. Background technique [0002] At present, emperor bamboo grass (forage grass) is being planted on a large scale in the south, processed and kept fresh, and then transported to the north for livestock feed. King bamboo grass has the largest stem diameter of 30mm and a height of more than 3 meters. The growth density is very large and it is very difficult to harvest. Due to the irregular terrain in the south, abundant rain, and slippery ground, the agricultural harvesters in the north cannot adapt. The current method of harvesting king bamboo grass is mainly manual harvesting. Due to the increase in labor costs and the high requirements of workers on the working environment, it is very difficult to harvest king bamboo grass on a large scale. ...
