Abstract

Disclosed is a hay cutter whose structure is that a motor drives a main shaft to rotate inside bearings arranged on both ends of the hay cutter; a large and a small shaft sleeves are arranged between the two bearings, and the inner side of the small shaft sleeve is provided with hay conveying centripetal reamer which forms a helical shape; the large shaft sleeve is fixed with a side blade and a hay discharging fan blade; the outside of each bearing is fixed with a belt pulley connected with the motor. Only one main shaft is dragged by the motor, and the conveyed hay is made to adjacent to the main shaft by a hat conveying centripetal reamer blade and then is cut by the side blade. The hay cutter has the advantages of simple structure, energy saving, high hat cutting speed, and favorable hay cutting rate.

Description

Hay cutter

The utility model is a kind of hay cutter tool device.

Present employed hay cutter, its structure is made up of two parts, the one, defeated careless mechanism, the 2nd, the hay cutter structure, motor drives a plurality of noncoupled axles by main axis rotation and rotates, it is middle by the bevel gear transmission, roll forward by a plurality of parallel toothed rollers when failing grass, in the middle of being sandwiched in, grass moves forward with spur roller gear, the front is the circular horizontal hobboing cutter of a rotation, drag directly grass by motor broken, the shortcoming of this kind hay cutter be the equipment complexity, huge, consumed power is big, noise is big, the use inconvenient maintenance.

For solving above shortcoming, the purpose of this utility model provides a kind of single shaft hay cutter, defeated grass is housed on a main shaft entad twists sheet, hand hay cutter blade and need not gear transmission, solved effectively that equipment is big, complex structure, wasted energy and use problem such as inconvenient maintenance.

Design of the present utility model is that the mechanical part centre of hay cutter is a main shaft (as shown in Figure 1), at the main shaft two ends is that front and back bearings supports, bearing is placed in the bearing block, be added with spring washer and bearing cap in the bearing outside, at the main shaft mid portion little axle sleeve and large shaft sleeve are housed, the entad strand sheet of defeated grass is housed on little axle sleeve, it is the sword sheet (as shown in Figure 2) that a spirality has saw blade that this defeated grass entad twists sheet, the side blade of vertical major is housed on large shaft sleeve, the chopper sheet is fixed on the fixed blade piece, the centre is fixed with screw, at large shaft sleeve the straw fan sheet is housed out simultaneously, between axle sleeve and main shaft, adorn hold-down screw, and keep one with main shaft, it is fastening with small sleeve in little axle sleeve outer end nut to be housed, be fixed with belt pulley in main shaft one side bearing outer end, by axle shelves ring, stop washer and nut are fastening in the belt pulley outer end.

Its course of work is when being placed on defeated grass by the hand hay cutter grass and entad twisting on the sheet, is a spirality because defeated grass entad twists sheet, with careless heave in, is cut off by the cutting edge on next door simultaneously, constantly advances, is constantly shredded, and grass bits chopped are taken away by going out the straw fan sheet.

The utility model and existing hay cutter relatively have following advantage: simple in structure, have only a main shaft, energy savings, fast, the broken carelessness of hand hay cutter grass speed good.

Detailed structure of the present utility model is provided by drawings and Examples.

Fig. 1 is the structure principle chart of hay cutter;

Fig. 2 entad twists chip architecture figure for the defeated grass of hay cutter.

Know by Fig. 1, (5) be the hay cutter main shaft, (4) and (18) be main shaft (5) before the back two bearings, (3) be the bearing of fore bearing (4), (2) be end ring, (1) is bearing cap, (11) be the bearing of rear bearing (18), (12) be check ring, (17) be bearing cap, (7) be little axle sleeve, its outside is fixing by nut (6), (10) be large shaft sleeve, in the middle of large shaft sleeve (10) and little axle sleeve (7), entad twist sheet (21) for defeated grass, this blade is fixed on the reamer fixture block (24) on the main shaft, on large shaft sleeve (10), be fixed with side blade (8), be fixed on the fixed blade piece (9), between fixing by screw (20), fixed blade piece (9) is fixed on the large shaft sleeve (10), in large shaft sleeve (10) inboard straw fan sheet (23) is housed out, fixing between large shaft sleeve (10) and the main shaft (5) by screw (19), end is equipped with belt pulley (13) outside main shaft (5), the outside is by axle bumper ring (14), stop washer (15) and nut (16) are fastening, add blade above it by a main shaft (5), just finish straw-cutting function, this machine model machine is through operation more than a year, respond well.
