Abstract

The utility model discloses a simple grain harvester, belonging to an agricultural machine. The simple grain harvester comprises an engine, a running mechanism, an operating mechanism and a threshing mechanism. The simple grain harvester is characterized in that: a ground-working type single-wheel system is used as the running mechanism; the bearing bar of the running single-wheel is fixed with a threshing box body which is provided with the threshing mechanism composed of stalk-blocking wheels and a threshing rotary drum; the power of the engine is transferred to a belt pulley arranged on the threshing box body by a belt and the belt pulley; the belt pulley drives the threshing rotary drum to rotate through a pair of gears, and meantime drives the stalk-blocking wheel to rotate through a chain; thus the rice threshing work is finished under the cooperation of the stalk-blocking wheel and the threshing rotary drum. The grain harvester only threshes grains without cutting off rice stalks, and with simple structure, light weight, convenient running and flexible operation, the grain harvester is suitable for hilly land, hill and especially the wet, soft and deep mud field in the south part of China to harvest rice. With low cost, and can be refitted into paddy field tillage machine, the utility model has the function of one machine serving a plurality of purposes, which is suitable for farmers to buy.

Description

A kind of simple and easy harvester

One, affiliated technical field:

The utility model relates to a kind of agricultural machinery, is a kind of preceding simple and easy paddy rice harvester of ploughing and leveling machine for paddy field that is installed in specifically.

Two, background technology:

China is the major production areas of paddy rice, particularly south, to produce in 1 year two season paddy rice, whenever the season of rush-harvesting and rush-planting, because of seasonality is strong, weather is hot again, for not missing farming season, reduce labor intensity, enhance productivity, vast farmers wishes to use rice harvester very much, however the rice harvester of developing in recent years, only little because of field, south rice field piece, be uneven, the mud pin is dark, makes big, the heavy grain header of body be difficult to put to good use its ability.

Three, summary of the invention:

Big, heavy in order to overcome existing rice harvester because of body, little irregular, environment that the mud pin is dark of field, incompatibility south rice field piece and price height, peasant such as are reluctant to buy at defective, the utility model provides a kind of volume little, in light weight, can be low in fluid mud field walking and price, be fit to the small-sized rice harvester that the peasant buys.

For solving its technical problem, the technical scheme that the utility model adopted is: selecting for use to be that power of the present utility model and running gear are not established rice bar cut-off mechanism at the Pu roll-type single wheel harvesting and tillage machine of paddy field walking.Promptly on the bearing bar of walking single wheel, be fixed with conversion belt pulley and a threshing casing, the front end of threshing casing is equipped with grain collecting wheel, the middle part of casing is equipped with threshing cylinder, side at the threshing casing is equipped with driving pulley, and link to each other with conversion belt pulley on the bearing bar by belt, be fixed with a pair of travelling gear in the rotating shaft of driving pulley, its driven gear drive threshing cylinder fast rotational, also be fixed with an initiatively chain wheel in the rotating shaft of driving pulley, link to each other with driven chain wheel in the grain collecting wheel rotating shaft by chain, rotate at a slow speed to drive grain collecting wheel, under the cooperatively interacting of grain collecting wheel and threshing cylinder, finish the threshing task of paddy rice.

The beneficial effects of the utility model are: 1. because the utility model employing Pu roll-type single wheel harvesting and tillage machine is power and running gear, therefore it can not only be walked on hillside, hilly ground and narrow road, can also in the peaceful rice field of rare ooze, walk, has only a road wheel because of this machine again, flexible operation, it is also very convenient to turn, smear the angle, is fit to gather in the narrow and small rice field of area; 2. because the utility model is to have additional grain collecting wheel and thrashing roller in single wheel harvesting and tillage machine front portion, do not establish rice bar cut-off mechanism, both straw was not cut off in a threshing, therefore volume is little, in light weight, and cost is low, being fit to the peasant buys, can satisfy the peasant paddy rice harvesting had both been wished that harvesting speed was fast, labour intensity is little, makes the low hope of harvesting cost again.3. because the utility model adopts " exempting to cut " scheme to the paddy rice straw, just the straw that took off grain, neat overwhelms on ground, after turning over harvesting and tillage machine, straw all can be gone back the field, increases the organic manure in rice field.

Four, description of drawings:

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model overall structure schematic diagram.

Fig. 2 is the structural representation of grain collecting wheel among Fig. 1, thrashing roller and transmission thereof.

Five, embodiment:

With reference to accompanying drawing: including engine (1); control stick (2); seat (5); bearing bar (6); on the bearing bar (6) of the existing single wheel harvesting and tillage machine of Pu roller (7); set up a big belt pulley (3) and a small belt pulley (4); big belt pulley (3) links to each other by the output shaft of belt with engine (1); bottom in bearing bar (6); be fixed with threshing cabinet (8); the front end of threshing cabinet (8) is fixed with grain collecting wheel (15) respectively by support (11); and thrashing roller (17); during this grain collecting wheel rotation; the straw-blocking rod that is provided with on the hub can be taken off the paddy rice spike of rice in the thrashing roller (17) that is poured on rotation after by forward direction; grain is taken off; be temporarily stored in the bottom of threshing cabinet; on the support of threshing cabinet (8), be fixed with belt pulley (13); this belt pulley is connected with small belt pulley (4) on the harvesting and tillage machine bearing bar by belt; be fixed with gear wheel (12) and chain drive gear (9) in the rotating shaft of belt pulley (13); gear wheel (12) is engaged with pinion (16); be fixed with threshing cylinder (17) in the rotating shaft of pinion (16); in the rotating shaft of the fixing grain collecting wheel (15) of threshing cabinet (8) front end, be fixed with chain driven gear (14); and link to each other with driven wheel (9) by chain, be provided with out the mouth of a valley and Ship shaped skateboard (10) in the bottom of threshing cabinet (8).During work; engine (1) promotes thresher casing (8) by Pu roller (7) and advances forward; and by belt drives belt pulley (13) rotation; on the one hand by rotating for the gear wheel of concentric shafts (12) and the pinion (16) that is engaged with drive threshing screw tube (17) with belt pulley (13); on the other hand by being the chain pitch wheel of concentric shafts (9) and (14) and the chain that matches with it with belt pulley (13); drive the result of the common rotation of grain collecting wheel (15) rotation, thrashing roller and grain collecting wheel two-wheeled, finish rice threshing work.
