Description

A kind of small harvester

Technical field

The utility model relates to a kind of agricultural machinery, relates to a kind of dynamic power machine grain header specifically.

Background technology

Over the past thousands of years, crops harvesting both at home and abroad all is to insist on the cutter harvesting with the people, and labour intensity is big, and efficiency is very low.Along with the development of agricultural machinery, grain header has been applied to the harvesting of large tracts of land crop belts, this large-scale grain header complex structure, and the cost height is not suitable for the small size operation of common peasant household.For addressing this problem, small harvester comes out.Be grain header at first based on reciprocating type cutting tool, this grain header efficient is lower, and then the rotary cutter type grain header appears, as ZL96243588.0, ZL96234056.1, ZL96239989.2, ZL99245551.0, the disclosed grain header of above-mentioned patent has and carries out paddy rice harvesting separately the paddy rice harvesting of carrying out is also arranged, the threshing combine, the main defective of rotary cutter is the plug grass very easily to take place cause cutter to rotate in operation, adopt rotary cutter to cooperate with fixed cutting tool and be equipped with gas on cutter structure blows out for this reason, though can solve the plug grass, but complex structure, the hilted broadsword of employing tool is also arranged, and this layout is limited by cutter frame structure, is difficult for the expansion number of cutters, cause operating efficiency low, moreover cutter mechanism is contained on the power-equipment of hand tractor one class, and the control of advancing is main hand steered by manpower, therefore walking is not steady, and cutter do not have the exercisable mechanism that adjusts height, only is applicable to the smooth paddy-field-working of small size, can't finish for knob dry land operation.The cterpillar drive smooth running, but only be disposed at present on the above farm machinery of 20KW, have not yet to see the report of not filling in the dual-purpose grain header in careless rotary cutter small-sized floods and droughts field with cterpillar drive.

Summary of the invention

The utility model is at the defective that existing small harvester exists, and it is simple to propose a kind of cutter configuration, can regulate the cutter height in the operation, advances steadily operating efficiency height, the small harvester that can carry out paddy field, dry land gramineous crop harvesting operation.

Finishing the concrete technical measures that the foregoing invention purpose taked is: a kind of small harvester, comprise power set, transmission device, and it is characterized in that: on the fixed support of grain header chassis, power set, transmission device are housed; At chassis fixed support two side lower parts cterpillar drive is housed; The fixed support front end is equipped with hydraulic means; Be fixed with travel(l)ing rest in the hydraulic stem upper end; In the travel(l)ing rest both sides lever arm is housed, the lever arm other end is contained on the fixed support; In the travel(l)ing rest one end outside transmission vertical shaft is housed, on transmission vertical shaft top belt pulley is housed, belt pulley is connected with transmission device with driving belt; Two drive sprockets are housed in transmission on the vertical shaft, be equipped with drive sprocket in the travel(l)ing rest other end outside corresponding by movable sprocket, drive sprocket be connected with chain by movable sprocket; Parallel installation grain delivering gear on chain; In the travel(l)ing rest bottom cutter platform is housed, the rotary tool axis lower end is contained in the rotary tool axis axle sleeve on the cutter platform, the rotary tool axis other end is contained in the axle sleeve on the travel(l)ing rest entablature, and belt pulley is equipped with in the rotary tool axis upper end, and belt pulley is connected with transmission device with driving belt; In the rotary tool axis bottom sprocket wheel is housed, minor axis is housed on the cutter platform side by side, minor axis one end on the cutter platform is equipped with sprocket wheel, and is connected with the sprocket wheel of chain with the rotary tool axis bottom; Minor axis one end below the cutter platform is equipped with rotary cutter, is equipped with to dredge to fill in above rotary cutter to revolve tooth, in the travel(l)ing rest front portion backplate is housed, and grass divider is installed outside backplate side by side.The beneficial effects of the utility model

Small harvester of the present utility model, adopt many group rotary cutters, and be equipped with on the cutter and dredge plug and revolve tooth, solved rotary cutter plug grass problem, rotary cutter is by hydraulic control system adjustment height, convenient, flexible, cut standing grain efficient height, running gear adopts crawler type travelling wheel, smooth running, grade climbing performance is strong, therefore, small harvester of the present utility model not only can carry out operation in smooth paddy field, and can carry out dry crops such as wheat, millet in the dry land that height rises and falls and gather in operation, enlarge the scope of application, economic benefit is obvious.

Small harvester compact conformation of the present utility model is reasonable, the operating system flexibility and reliability, and cost is low, for common peasant household can accept.
