Abstract

The utility model relates to a hay cutter belonging to farm and herd machines. The cutter is equipped with a gear box; the output shaft end of the gear box is equipped with a driving chain wheel which is separately connected with a hay feed chain wheel and a hay feed roller chain wheel which is arranged at the end of the upper and lower hay feed roller shafts by chains and guide chain wheels in a driving way; a cutter wheel comprises right and left sections and every section of the knife wheel is separately equipped two pairs of knifes which form an included angle of 180 degrees; the two knifes are arranged in a cross pattern on the two section of knife wheel; the upper port of the fan tube is equipped with a universal elbow in a tilted way; a hay outlet is communicated with the fan tube. The cutter can cut hays of different lengths and the efficiency can be increased by more than one third compared with the traditional cutter if the feed port is not changed; at the same time the soot rate is greatly reduced.

Description

Hay cutter

Technical field:

The utility model relates to a kind of hay cutter, belongs to agriculture and animal husbandry machinery.

Background technology:

Though known hay cutter has various ways, it is controlled into careless power drive mechanism and mostly is gear drive, generally can not change into careless speed, that is can not be adjusted to the length of material grass, the stall or the counter-rotating of the upper and lower grass-feeding roller of more difficult realization.Moving knife adopts two rimmer knifes, and power consumption is excessive.Wind pushing mechanism go out that careless direction be difficult for to be adjusted, flue dust is big, environmental pollution is serious.

Summary of the invention:

Goal of the invention of the present utility model provides a kind of length that can change over material grass as required, goes out careless high, the little hay cutter of environmental pollution.

The technical scheme that realizes the foregoing invention purpose is: the parts of this hay cutter are formed and are comprised frame, advance careless conveyer belt, advance careless conveying roller sprocket wheel, go up grass-feeding roller, lower grass-feeding roller, moving knife assembly, wind pushing mechanism, gearbox is housed on the frame, the output axle head of this gearbox is equipped with drive sprocket, this drive sprocket by chain and jockey sprocket respectively with advance careless conveying roller sprocket wheel and be installed in the careless conveying roller chain gear transmission of advancing of grass-feeding roller and lower grass-feeding roller axle head and be connected; Two joints about cutterhead in the moving knife assembly comprises are equipped with two pairs of moving knife that are mutually 180 ° of angles respectively on every joint cutterhead, and between the moving knife of two joints on the cutterheads with cross-shaped installation; Fan blower in the wind pushing mechanism is installed in frame lower, and its air duct that is obliquely installed is suitable for reading to be equipped with universal elbow, is arranged on grass outlet and this air duct UNICOM of moving knife assembly shell horizontal direction.

In the technical program, gearbox is controlled the rotating speed of upper and lower grass-feeding roller by chain type transmission mechanism, realized changing over as required the purpose of the careless length of material, also improved simultaneously processing safety, the moving knife mechanism that two joint cutterheads and four pairs of moving knife that intersect mutually, stagger thereof constitute, under the constant situation of feeding mouth, improve effect more than 1/3 than traditional hay cutter, the wind pushing mechanism of torch-type can be by changing the distance that the fan blower belt pulley is adjusted to the ejection of material grass, universal elbow changes emission direction arbitrarily, and dust rate reduces greatly.

Embodiment:

Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.The described hay cutter of present embodiment by frame 1, advance careless conveyer belt 2, advance careless conveying roller sprocket wheel 3, driving chain 4, jockey sprocket 5, go up parts such as grass-feeding roller 6, enterprising careless roller chain 7, lower grass-feeding roller 8, lower grass-feeding roller sprocket wheel 9, moving knife assembly 10, moving knife assembly shell 11, air duct 12, universal elbow 13, fan blower 14, stationary knife 15 gearboxes 16, drive sprocket 17, handle 18 and constitute, all parts are the mounting support point with frame 1 all.Gearbox 16 also is housed on the frame 1, the output axle head of this gearbox 16 is equipped with drive sprocket 17, and this drive sprocket 17 is in transmission connection with the grass-feeding roller sprocket wheel 7,9 that advances careless conveying roller sprocket wheel 3 and be installed in grass-feeding roller 6 and lower grass-feeding roller 8 axle heads respectively by chain 4 and jockey sprocket 5.Can regulate the rotating speed of drive sprocket 17 by handle 18, and then change the rotating speed of upper and lower grass-feeding roller 6,8, simultaneously by advancing the defeated careless speed that careless conveying roller sprocket wheel 3 changes into careless conveyer belt 2, because of advancing the length of the disconnected one-tenth material grass of careless speed decision hand hay cutter, so this hay cutter can cut up with a hay cutter out the one-tenth material grass of three kinds of different sizes.When potential safety hazard appears in the operator, also can realize grass-feeding roller stall or reversing by gearbox 16, to eliminate safe hidden trouble by handle 18.Two joints about cutterhead 27 in the moving knife assembly 10 comprises, be welded on respectively on the cutter axis 29, two pairs of moving knife 28 that are mutually 180 ° of angles are housed respectively on every joint cutterhead 27, and install with right-angled intersection, the shape that staggers between the moving knife 28 on the two joint cutterheads 27, make four pairs of moving knife 28 successively at an angle of 90, the stationary knife 15 that cooperates with this moving knife 28 is fixed on the frame 1, it and upper and lower grass-feeding roller 6,8 ask that crack and cutter axis 29 are on a horizontal plane.Fan blower 14 in the wind pushing mechanism is positioned at frame 1 bottom, and its air duct that is obliquely installed 12 is suitable for reading to be equipped with universal elbow 13, is arranged on grass outlet and this air duct 12 UNICOMs of moving knife assembly shell 11 horizontal directions.The power wheel of present embodiment is installed in cutter axis 29 1 ends in the moving knife assembly, these cutter axis 29 two ends are equipped with belt pulley 19 and 24 respectively, two belt pulleys respectively by driving-belt 20 and 23 and air blast wheel 21 and gearbox 16 on belt pulley 22 be in transmission connection, change the distance that this air blast wheel 21 just can be adjusted to material grass ejection.

In the present embodiment, extension spring support 25 is equipped with by frame 1 in last grass-feeding roller 6 tops, between this support 25 and last grass-feeding roller 6 extension spring 26 is housed, and under the effect of this extension spring 26, along with advancing what of grass, last grass-feeding roller 6 can be upper and lower thereupon moves, and grass is at the uniform velocity advanced in assurance.
