Abstract
The utility model discloses a broken grass machine, which comprises a machine frame, a cutter and a transmission shaft which is fixed on the machine frame by a shaft block, and also comprises a cover tube which is fixed on the machine frame. The transmission shaft is arranged in the cover tube. The transmission shaft of the broken grass machine in the utility model penetrates through a square pipe arranged on the machine frame; when the broken grass machine operates, the transmission shaft is covered in the square pipe, which can avoid the enlacing of the transmission shaft with the grass in the rotary motion, avoid the distortion and even rupture of the transmission shaft, and greatly increase the durability and reliability of the broken grass machine.
Description
Technical field
The utility model belongs to agricultural mechanical field, relates to a kind of meadow operation mower.
Background technology
On the more smooth native pasture of artificially sown pastures or physical features, during traditional mower operation, the power transmission shaft of mower be exposed outside.When beating the grass, because rotatablely moving of the power transmission shaft of mower causes the grass of cutting to be wrapped on the power transmission shaft easily, and then cause power transmission shaft to happen occasionally because of the excessive situation of being out of shape even rupturing of moment of torsion resistance.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model is to provide a kind of grass that can avoid cutting to twine the facility of beating the grass that the power transmission shaft phenomenon produces.
For achieving the above object, a kind of mower of the utility model comprises frame, cutter and power transmission shaft, and power transmission shaft is fixed on the frame by bearing block, also comprises sleeve pipe, and this sleeve pipe is fixed on the described frame, and described power transmission shaft is installed in this sleeve pipe.
Further, described sleeve pipe is a square steel tube.
Further, also comprise hydraulic jack, this hydraulic jack is fixed on the described frame, and the free end of the piston rod of hydraulic jack links to each other with the stationary knife of described cutter.
Further, also be provided with the jockey that links to each other with tractor on the described frame.
Further, described jockey is that angle steel and the hanger that is arranged on the described frame formed.
Compared with prior art, the power transmission shaft of the utility model mower from frame be provided with square tube in pass, during the mower operation, power transmission shaft is coated in the square tube, prevent that power transmission shaft from causing power transmission shaft and grass to twine in rotatablely moving, avoid the distortion even the fracture of power transmission shaft, increased the durability and the reliability of mower greatly.
Description of drawings
Fig. 1 is the structural representation of the hydraulic jack side of the utility model mower;
Fig. 2 is the structural representation of the wooden connecting rod side of the utility model mower.
Embodiment
Below in conjunction with Figure of description the utility model mower is further described:
Among Fig. 1 and 2, be fixed with square steel tube 8 on the frame 7 of mower, power transmission shaft 10 passes in square steel tube 8, one end of power transmission shaft 10 is fixed on the frame 7 by bearing block and is connected with belt pulley 5, the other end also is fixed on the frame 7 and with eccentric wheel 4 by bearing block and links to each other, link to each other by wooden connecting rod 2 between eccentric wheel 4 and the cutter moving knife 1, below frame 7, hydraulic jack is installed, the cylinder barrel 3 of hydraulic jack is fixed on the frame 7, the output of the piston rod 11 of hydraulic jack and the stationary knife 12 of cutter fix, the moving knife 1 of cutter is installed in the top of stationary knife 12, and the upper surface of frame 7 is provided with angle steel 9 and four hangers 6.
The utility model mower uses with tractor, during work, the frame 7 of mower is articulated in the below of tractor by angle steel 9 and hanger 6, angle steel 9 is in the lifting of the rear portion of tractor, the power take-off of tractor by its belt pulley that has to extraneous outputting power, the power of tractor is delivered on the belt pulley 5 of mower by belt pulley, thereby belt pulley 5 rotates and drives power transmission shaft 10 rotations, power transmission shaft 10 transfers torque on the eccentric wheel 4, and rotatablely moving of eccentric wheel 4 changes into the reciprocating motion of wooden connecting rod 2.During operation, drive and traction by tractor, the hydraulic pump of tractor drives the hydraulic jack of mower earlier, and the cylinder barrel 3 of hydraulic jack is fixed on the frame 7, under the promotion of hydraulic oil, piston rod 11 motions of hydraulic jack, by the anterior rotating shafts restriction of piston rod 11, piston rod 11 is the center with the rotating shaft, carries out lever motion, thereby other end cutter is put down, parallel with ground.The moving knife 1 of cutter motion when beating the grass, grass enters between the moving knife 1 and stationary knife 12 of cutter, and the moving knife sword of cutter and stationary knife sword are cut off grass as scissors.Beat the grass finish after, the hydraulic jack of the hydraulic pump reverse drive mower of tractor, with the cutter perk, be convenient to the transportation.
Compared with prior art, the power transmission shaft 10 of the utility model mower is arranged in the square steel tube 8, therefore, just can not cause power transmission shaft 10 and grass and twine when beating the grass owing to rotatablely moving of power transmission shaft 10, prevented that power transmission shaft 10 is out of shape because of the moment of torsion resistance is excessive even ruptures, and has increased the durability and the reliability of machine greatly.Simultaneously, angle steel 9 and four hangers 6 of being provided with on frame 7 are convenient to being connected of mower and tractor.In addition, traditional mower is by the hydraulic arm on the tractor, steel wire rope on the pulling cutter is realized the lifting and the decline of cutter, hydraulic arm will occur through operation repeatedly like this and be dragged disconnected phenomenon, and the lifting of the cutter of the utility model mower and putting down, be to realize simple in structure, reliable operation by the hydraulic jack that frame 7 belows are provided with.
