Description

Miniature combine harvester

The utility model relates to a kind of farm machinery, specifically is miniature combine harvester.

Existing agricultural grain header, complex structure mostly, bulky, the structure heaviness needs manually paddy rice to be cut a circle as passage before the work, the operation of can going to the field, reduced operating efficiency, and limit, field corner can't gather in the complete machine difficult, maneuverability is poor, can not adapt to the nonirrigated farmland, paddy field and the dark partially paddy-field-working of some mud pin of a large amount of knob small size in China south of the River.

The purpose of this utility model provides a kind of miniature combine harvester at the problems referred to above exactly, have in light weight, volume is little, operation tube just turns to flexibly, can be widely used in the nonirrigated farmland, paddy field of China knob, has the threshing one step completed characteristics of mowing.

The technical solution of the utility model is: by frame; traveling mechanism; take off standing grain mechanism; the corn harvester structure; send standing grain mechanism and separating mechanism and transmission mechanism to form; the structure of wherein taking off standing grain mechanism is that both sides are nearside divider; roll for blocking standing grain the centre; the corn harvester structure is a horizontal push-shear formula structure; scissors is wider than fuselage; send the conveyer belt and the scissors of standing grain mechanism wide; the one end directly is contained in the back lower place of scissors; the other end then reaches in the shell of separating mechanism; separating mechanism is to be made of cased threshing cylinder and screen cloth; have out the mouth of a valley and grass outlet on the shell; the road wheel of traveling mechanism is contained on the main shaft that travels; the main shaft that travels then passes through transmission mechanism; gearbox and clutch connect with power; block that standing grain rolls and threshing cylinder all connects with power by transmission mechanism; conveyer belt is installed on the roller bearing; roller bearing passes through sprocket wheel; chain drive connects with power; scissors is fixed on the scissors fixed mount; the scissors fixed mount successively with the crankle arm; universal ball end; pull bar; connecting lever connects, on the sprocket wheel that connecting lever then is contained in power connects.

According to technique scheme, power drives road wheel walks complete machine in the rice field.It is moving to block the standing grain lift-over, rice is inwardly taken off, and the spike of rice that cuts off taken off on the conveyer belt, nearside divider then separates the rice on both sides, the scissors of corn harvester structure cuts off rice, because scissors is wider than fuselage, thereby has changed the in the past the sort of trouble that need manually cut rice one circle as passage before the work of going to the field, greatly improved operating efficiency, simultaneously, conveyer belt and scissors are wide, and an end directly is contained in the back lower place of scissors, like this, the rice of cutting off directly is poured on the conveyer belt, has saved traditional screw impeller, has alleviated weight and simplified structure, the rice of cutting off is delivered in the threshing housing by conveyer belt, threshing cylinder rotates, and carries out threshing, because threshing is to adopt the hand of spiral to hit tooth, make threshing faster, cleaner, grain directly falls into grain-containing bag through screen cloth by the mouth of a valley that goes out on the shell, has saved auger, makes structure more simple, complete machine weight is lighter, and straw is then gone out from grass outlet.

Screen cloth in the separating mechanism of the present utility model is whole steel plate type screen cloth, makes long service life.

The scissors of corn harvester structure of the present utility model all is contained on the transportation frame with the conveyer belt that send standing grain mechanism, and the transportation frame then is connected with the hydraulic pressure top, promptly can regulate the height of scissors and conveyer belt by the hydraulic pressure top.

Therefore, the compact conformation of the micro combined harvesting that the utility model provides, in light weight, volume is little, turn to flexibly, easy and simple to handle, can reach arbitrary purpose, mow and threshing is disposable finishes, the waste rate is extremely low, lower than hand harvest's waste rate, while function admirable, good looking appearance, applicability is good, and use in the dark partially paddy field of paddy field, nonirrigated farmland and some mud pin that can be widely used in China knob.

Describe structure of the present utility model in detail below in conjunction with the embodiment accompanying drawing.

At first accompanying drawing is described:

Fig. 1 represents structural front view of the present utility model;

Fig. 2 represents structure vertical view of the present utility model.

Referring to accompanying drawing; the utility model comprises frame and traveling mechanism, takes off standing grain mechanism, the corn harvester structure, send standing grain mechanism and separating mechanism and transmission mechanism; the structure of its mid frame and traveling mechanism is: grain header frame 29 and thresher frame 41 welding or bolt, and interconnect fixing with gearbox 30.Power is passed to the power shaft sprocket wheel of gearbox 30 by belt pulley, V belt by diesel engine 1, passing to the main shaft 22 that the travels wheel that travels by sprocket wheel 25,23, chain 24,

clutch

37,36 again 31 is contained on the main shaft 22 that travels, wheel 31 symmetries of travelling are equipped with two, there is tail wheel 26 back, 27 is supporting shaft, and clutch control handle 4 is connected with the disengaging yoke 39 of clutch 37 and is fixed on the handle 2.38 is clutch spring; 42 is throttle control handle; 43 is main clutch; 40 is bearing block.

The structure of taking off standing grain mechanism by block standing grain roll 13 and nearside divider 34,54 form, they are separately fixed on bearing support 14 and the transportation frame 11, drive and block standing grain and roll 13 rotations thereby its transmission drives belt pulleys 55 by V-belt 12,15 is the nearside divider attached frame, 32 for blocking the standing grain broach.

The structure of corn harvester structure is: horizontal push-shear 33 is fixed on the scissors fixed mount 16, fixed mount 16 is connected with transportation frame 11 usefulness bolt, the motion of scissors 33 is by sending the sprocket wheel 47 on the standing grain mechanism shaft to pass to scissors 33 by connecting lever 49, pull bar 50, universal ball end 52, crankle arm 53, make scissors 33 produce cutting movement, 17 is dividing plate.
