Abstract

The utility model relates to a harvester which is characterized in that a sawing device is assembled by one or a plurality of round metal sawing discs, has a small resistance, takes a small scale engine as power, a power wheel of the sawing device is shape by the injection of an engineering plastic, and one piece of rubber pedrail is taken as a running gear, which all together solves the current problems such as overheavy weight and poor trafficability of the engine body; the phenomenon that wheels sink in the cultivations of the paddy fields can be prevented; a threshing mechanism of the utility model is a disc plane shape and a rotary type and has a plurality of threshing components of a plurality of types positioned below; the threshing components in running can strike the paddy rice and wheat grains repeatedly and completely; a fan can be used for producing a pressure and further sending the paddy rice and wheat grains into packages, ultimately realizing an automation in the entire harvesting course.

Description

A kind of grain header

The utility model relates to a sharp agricultural machinery, and especially it has functions such as harvester for rice wheat and soybean.

Present known harvesting machinery has multiple model, full feed type and two big classes semi-feeding type are wherein arranged, according to known to, the grain header of this two type all is to adopt to cut segmentation method crop is cut off, and cuts segmentation method owing to adopt, and working resistance is bigger, required also big with horsepower, cause the body moulding huge, bring body matter heavily to increase, the difficult problem of wheel phenomenon and trafficability characteristic difference appears falling in most types to the paddy rice area of some mud pin Tian Shen of south.

The harvesting machinery of comparatively advanced at present employing rubber belt track walking, " Taihu Lake board " 1450 type harvester for both rice and wheat of producing with Jiangsu Province Wuxi Combine Harvester Factory are as the criterion, long 3950 millimeters of this body, wide 1800 millimeters, high 1810 millimeters, body weighs 2000 kilograms, the comparatively advanced grain header of just Japanese " the foreign horse board " that produces, its complete machine matter is heavy also to reach 1970 kilograms, and body matter is heavy excessive, runs into the difficult problem of trafficability characteristic difference in area, paddy field, China south.

The purpose of this utility model is: the harvesting machinery that a kind of brand new is provided, its structural feature is, the sawing device that adopts one or more sharp metal saw dish (5) to be assembled into, has body gently little (long 2000 millimeters of body, wide 1000 millimeters, height does not surpass a meter), heavily about 200 kilograms of complete machine matter, belong to the small-sized self-propelling combine that partly feeds, it is to adopt rubber belt track to make running gear, can solve the difficult problem of south rice area trafficability characteristic difference.

The utility model is achieved in that sawing device (5) is mounted on the face of belt wheel.Saw dish major part is covered in by iron sheet, only expose forward position part sawtooth as the sawing crop, transmission by the V-belt, make this device high speed rotating, thereby crop is cut off, reach the harvesting purpose, the crop of being cut off, be held conveying backward through conveying plant (4), this conveying plant is made up of two conveyer belts of existing side by side, the export-oriented face of this conveyer belt is pasted with many waveform adhesive tape, its effect is that crop can be clamped in course of conveying securely, can carry out threshing synchronously, it is to adopt dish-like plane revolving that this sheller unit (6) is arranged on top (as shown in drawings) sheller unit (6) of conveyer belt (4), the bow profile of tooth threshing assembly of multiple model is installed below this device, adopt the triangle transmission, make its high speed rotating, take off thereby crop branch fringe can be impacted repeatedly comb, its seed is purified, realize receiving and take off purpose, the rice wheat grain that is come off falls into the collection grain bucket that is arranged on conveyer belt (4) both sides, collection grain bucket and blower fan are combined into one, and utilize the blast pipeline that rice wheat grain is blown into packaging bag, and its impurity (not full grain and grass are broken) is because light weight, be blown away at pipeline exit, mature grain can freely fall in the collection tanker.

The utility model is to adopt the brand new technical structure, it is characterized in that: adopt one or more sharp metal saw dish to form the sawing device, adopt special rubber belt track to make running gear, crawler belt is subjective basis with the conveyer belt, interior the arrangement by certain distance to face at crawler belt is pasted with many leg-of-mutton annular adhesive tape, export-oriented face at crawler belt, be pasted with projection horizontal stripe adhesive tape or other figure adhesive tape by the certain distance arrangement, it is blade tooth as walking usefulness, its walking power wheel is to adopt the injection mo(u)lding of engineering plastics glue, each outer garden face of taking turns of walking power wheel has many annular tunnels, triangle adhesive tape to face in the size in these tunnels and the crawler belt matches, its effect is that the power belt wheel can be used as fixedly crawler belt again, prevents from the crawler belt displacement and take off zoning to take place.

The utility model accompanying drawing is a plane structure chart.

Description of drawings: (1) engine, (2) power transmission shaft, (3) simple and easy clutch, (4) vertical conveyor, (5) sawing device, (6) sheller unit, (7) grain lifter, (8) plate washer, (9) gear-box.(10) rubber belt track.

The utility model is to implement like this, by engine (1) outputting power, pulling power transmission shaft (2) running, be arranged in the power transmission shaft (2) a plurality of belt wheels are arranged, (seeing accompanying drawing) and a simple and easy clutch, pass through clutch action, but the various device operations of transmission, realize harvesting, threshing, requirements such as removal of impurities, crop enters sawing device (5) and plate washer (8) and is got into vertical conveyor (4) and be held and carry backward through grain lifter (7), enter in the threshing scope promptly and to be impacted comb repeatedly by the bow tooth assembly below the dish-like plane threshing device (6) and take off rice wheat grain is purified when the crop very first time in course of conveying, gear-box (9) is to dial to device by the clutch of setting in the belt wheel transmission case of power transmission shaft (2) latter end, realize its output, turn to, stop, function such as open, drive to turn to and adopt steering wheel to realize.

The utility model since adopt sawing crop method with existing adopt to cut cut the crop method relatively, it is little that it has a resistance, can adopt put-put to be used as power, (containing below 8), it was simple in structure, and volume is little, and is in light weight, be a kind of multiple functional small harvester tool, can realize gathering in automation, have harvesting, threshing, carry, functions such as removal of impurities, as install shredding mechanism additional, also can synchronously crop straw be cut into several sections, help straw and go back to the field.

The utility model and existing harvesting machinery are in structure and former existing entirely different.
