Description
Technical field
The present invention relates to field of agricultural machinery, more particularly to a kind of terraced fields open up wasteland equipment.
Background technology
Terraced fields, which are opened up wasteland, at present generally uses the equipment such as bull-dozer, tractor, excavator, loading machine.When these equipment work
Operation cannot be continuously promoted, the resistance in digging is big.Also have using a kind of throwing machine, can work continuously, but throwing component
Speed is high, and serious wear, power dissipation is big, and the mode that fetches earth is still using shovel modus ponens, and resistance is big, and the terraced fields of build are lack of standardization.State
Inside there are pick formula terraced fields to open up wasteland device, be the pick for securing plane soil on helical axis, can be worked with positive and negative rotation, machine driving can be with
It is used on tractor, bull-dozer, there are defective：As shown in Fig. 1, because of the presence of body traverse feed, pick
It is misaligned in the other end practical work of cutting edge operation rule mark and pick, other end can rub with raw-soil face, and power consumption is because of cross
It is steeply risen to the increase of feed speed, so that cannot work；Its body is short, does not adapt to the terraced fields of wide cut；Machine driving
Flexibility is poor, high failure rate.
Chinese patent CN201410845062.2 discloses three sections of cutting type terraced fields of one kind and opening leveling device, including cutting master
Machine, characterized in that the scraper bowl that the cutting host substitutes side turn over loading machine is hinged on side turn over loading machine, in side turn over
The both sides of loading machine have been hinged left side screw conveyor and right side screw conveyor by hinged shaft, and have coupled radial type respectively
The hydraulic cylinder of installation, hydraulic cylinder elongation can drive left-hand screw conveyer or right-hand screw conveyer to turn to cutting type master by both sides
The left end or right end of machine；The cutting host includes a main shaft, and main shaft is evenly equipped with bite, and main shaft is by two hanger bearings
Seat is connected on casing, gear is also mounted on main shaft, input shaft and the hydraulic motor of gear are connected；It is described
Left side screw conveyor it is identical as right side screw conveyer structure, symmetrical fabrication and installation, all include a long axis, long axis
Distributing auger blade, long axis are connected in by hanging axis bearing on casing by cutting one side of host, and the other end of long axis is circumferentially equal
It is even to secure several switch-plates, it is also connected on the end plate of casing by F type bearing supports, spindle nose and the hydraulic motor of long axis join
It connects.
Three sections of cutting type terraced fields of the patent disclosure open leveling device, and the axial transport of earth excavation still depends on spiral
Conveying mechanism substantially fails to solve the problems, such as that power consumption steeply rises because of the increase of traverse feed speed, and this three cuts off and cut
Formula terraced fields, which hold leveling device and encounter rubble at work, can damage machinery, of high cost and efficiency is low.
