Embodiment Construction
[0011] A structure of extruding type root digging device, such as figure 1 , figure 2 As shown, when working, the mobile walking machine moves so that the plant to be dug is placed in the middle of the two root digging knives (6) of the excavation device, and the lifting platform (5) of the root digging device moves along the lifting direction under the action of the lifting piston (13). The slide rail (15) is adjusted so that the root-digging knife (6) is close to the soil surface, and the angle between the root-digging knife (6) on both sides is adjusted by controlling the expansion and contraction of the clamping piston (2) according to the size of the plant to be dug. When the root is deep, the angle between the two root knives (6) is small, and when the root system is shallow, the angle between the root knives (6) is increased; by controlling the extension speed of the root knife piston (11), that is, to dig the root The extension speed of the knife (6) is combined with...

The invention discloses an extrusion type root digging device which is characterized in that the whole device is fixedly connected with a movable traveling machine through a frame (1). A lifting table (5) is connected with the frame (1) through a lifting slide rail (15) through a sliding pair. A lifting oil cylinder barrel (12) is fixedly connected on the frame (1), and a lifting piston (13) is hinged to the lifting table (5). A clamping oil cylinder barrel (3) is fixedly connected on the lifting table (5), a clamping piston (2) is hinged to an upper clamping connecting rod (4), the upper clamping connecting rod (4) is hinged to lower clamping connecting rods (9), the two lower clamping connecting rods (9) symmetrical bilaterally are hinged to the lifting table (5) through a pin (14), a root digging knife oil cylinder barrel (8) is fixedly connected with the lower clamping connecting rods (9) through a root digging knife oil cylinder base (10), a slide (7) is fixedly connected on the root digging knife oil cylinder barrel (8) and the root digging knife oil cylinder base (10), a root digging knife (6) is fixedly connected with a guide rail (16), a root digging knife piston (11) is fixedly connected with the root digging knife (6), and the guide rail (16) is connected with the slide (7) through a sliding pair.
Description
technical field [0001] The invention relates to a root digging device, in particular to a mechanical root digging device which discretely squeezes the soil structure of the roots, facilitates root extraction, reduces resistance to soil penetration, and does not turn over the soil. Background technique [0002] Dominant weeds such as chamaema chamaejasma and Malian have seriously damaged the ecology of the grassland and need to be eliminated, but it is required not to plow the soil or disturb the soil, otherwise the grassland will be degraded. The root of chamaejasma has high medicinal value and needs to be excavated on the premise of protecting the ecology. At present, the existing root digging devices at home and abroad will take out the soil bonded by the roots while removing the roots, disturbing and turning the soil, which will easily cause land desertification and damage the grassland ecology. Grassland soil is relatively dry most of the time, and it is easy to dispers...
