Description

Small harvester

Affiliated field

The utility model relates generally to a kind of farm machinery, particularly a kind of small harvester.

Background technology

In the farm work in rural area, the harvesting paddy and wheat is one of bigger farm work of labour intensity, operated by hand in the rural area in the past, the peasant brandishes reaping hook and cuts wheat, cuts rice, very arduous, gather in agricultural machinery gradually in the rural area that is located in the Plain, but be in the mountain area, and China south of hilly country but can't the higher agricultural machinery working of service efficiency.Also there are some midget plants to come into operation, as have a running gear, and have a small harvester of cutter sweep, running gear has crawler type or two-wheel, four-wheel, though crawler type is fit to soft ground, field, but its complex structure, cost is also corresponding high, in the wheel of general wheel type traveling mechanism is absorbed in easily and loosens the soil, and wheels is also wanted a cover power drive mechanism, complex structure, the practicality of said apparatus is not strong, therefore develops a kind of small-sized reaping apparatus that can overcome above-mentioned known technology shortcoming and is necessary.

The utility model content

The purpose of this utility model is to provide a kind of can overcome the known technology shortcoming, price economy, the small harvester of manipulating with adapting to floods and droughts.

For adapting to above-mentioned purpose, scheme of the present utility model is: comprise a minitype motivation source, described power source is installed on the flat-bottomed boat-shape base, and the output shaft of power source and a transmission device join, and a transmission device and a cutting device join.

Further scheme comprises that described minitype motivation source comprises miniature gasoline engine or small diesel engine.

Adopt such scheme, miniature gasoline engine or small diesel engine cutter sweep direct by actuating unit and the rice wheat joins, and be installed on the flat-bottomed boat-shape base, rely on base directly to slide on the ground, saved the mechanical device of running gear like this, alleviate weight, also reduced cost of manufacture, thereby realized the purpose of this utility model.

Below in conjunction with diagram and embodiment scheme of the present utility model is described in more detail.

Embodiment

Small harvester as shown in Figure 1 is provided with a miniature gasoline engine 1 source that is used as power, and the gasoline engine model of present embodiment is the YJIE43F type, and power is 3.2 horsepowers, and the gasoline engine volume is 32 * 30 * 25 (centimetres) ³Weight is 18Kg, gasoline engine is installed on the support 2 of stool form, there is the location benchmark upper surface of support 2, bolt hole by the upper surface is fixedlyed connected gasoline engine with bolt with support 2, the lower end of four under-chassis of support 2 and a flat-bottomed boat-shape base 3 are affixed, and present embodiment is fixing with welding, can certainly adopt other connected modes.Described flat-bottomed boat-shape base 3 is a rectangle, also can adopt circle or other can form the shape of area, and the area area more shared than gasoline engine is bigger, slightly go up volume all around, wing 4 is stuck up in formation, and the output shaft of gasoline engine 1 joins by an arrangement of clutch and an actuating unit, as described in Figure 2.The actuating unit of present embodiment comprises one group of reduction of speed belt transmission 5, one first driven pulley 6 is supported by power transmission shaft 7, power transmission shaft 7 is installed on the bearing block 8, bearing block 8 be installed in the affixed cushion block 9 of support 2 on, the other end of power transmission shaft 7 is overhanging to join with cutter sweep, power transmission shaft 7 is enclosed within the metal tube 10, metal tube 10 is fixed on the bearing cap 11 near an end of bearing block 8, usually metal tube 10 directly is welded on the bearing cap 11, metal tube 10 overhanging formation cantilever levers, the other end is fixedlyed connected with a housing 12, in the housing 12 bevel-gear sett is housed, the transmission axle head 14 of driven wheel of differential 13 is equipped with a rectangular blade 15, power transmission shaft 14 is by a pair of roller bearings, or adopt sliding bearing support all can, on housing 12, also fix a pair of angled bar 16,17, so that cut rice, hold together straw etc. during wheat and be used for cutting.

The transmission principle of said apparatus comprises: by miniature gasoline engine power transmission shaft outputting power, driving power transmission shaft 7 by driven pulley 6 after belt drive unit slows down rotates, power transmission shaft 7 is by a pair of roller bearings on the bearing block 8, so transmission loss is less, because power transmission shaft 7 is enclosed within the metal tube 10,, and be delivered on the bearing block by metal tube 10 so overhanging weight is almost born by metal tube, arrive support then, form the sealing of power.Adopt rectangular blade to be more convenient for cutting straw, rice bar etc. than circular shear blade.

Embodiment 2

Present embodiment uses small diesel engine to be used as power, and described small diesel engine model is the JK60FA type, 2 kilowatts of power outputs, volume 40 * 25 * 33 (centimetre) ³Power take-off at small diesel engine is connected with one group of deceleration belt dressing, on the wheel disc of one second driven pulley 18, establish one group of eccentric stiffener device, driven pulley 18 is supported by support 19, described eccentric stiffener is included in the wheel disc card and is provided with an eccentric pivot pin 20, one end of a connecting rod 21 is porose to be cooperated with pivot pin 20 activities, movable cutter hub 22 cooperates by setting element is movable with a fixed cutter body 23 that is fixed on the frame, the other end of connecting rod 21 also cooperates with movable cutter hub 22 activities in the cutter sweep by pivot pin, be equipped with cutter tooth on the edge of movable cutter hub 22 and fixed cutter body 23, the setting element of present embodiment is one pair of dovetail device 24, can certainly adopt the setting element of other modes.

The motion mode of present embodiment device comprises that the eccentric stiffener drivening rod 21 that utilization is provided with does plane motion on driven pulley 18, connecting rod 21 drive activity cutter hubs 22 are reciprocating along the dovetail positioner, thereby the tooth on the cutter hub one is opened one and is closed and cut off straw, and this is to understand easily.

Adopt the minitype cutting machine of the application's scheme, owing to removed loaded down with trivial details running gear, and directly adopt the ship shape base plate, not only weight saving, the grain header gross weight that gasoline engine is installed is 15Kg, cost of manufacture descends, but do not influence its operation, and efficient is higher, and efficient is for per hour cutting 1 mu, because the bottom surface of ship shape base plate is smooth, the straw that cuts down, straw covers on the soft soil, field, the bottom surface of grain header contacts with straw, forms a bed course of being made up of straw, so forms sliding friction between base plate and the straw, if field ponding, because base plate is a ship shape, also be difficult for water inlet, at this moment the operator grasps barre 25, with some power grain header is moved ahead a little, this suitable southern hills area with the operation that harvesting machinery replaces the peasant to bend over to wave sickle, will obtain promoting in practice.
