Abstract

The utility model discloses a rice cutter-thresher capable of threshing before the stalk is cut, which adopts a technology of first threshing and second cut and is composed of a cutting-threshing part, a walking part, and a load bearing part which can be assembled quickly. The new techniques, a sponge barrel type reel basket, a screw feeder type cutter, an arch tooth type derived wheel, etc., are adopted. The utility model has the advantages of simple structure, less power consumption, reasonable overall configuration, small spray loss, good passing performance, etc. The utility model is used for cutting and threshing crops with different height as well as the bended and ragged crops; the utility model can work on the deep mud field of a lake district, and can work on the dry field. The advantages of the utility model is shown when the utility model works on the small rice fields of the mountain area, the hilly area, etc.

Description

Rice cutter-thresher with thresh before the stalk is cut

The utility model belongs to a kind of small-sized rice results machine, is particularly useful for the torrid zone, the small piece paddy field operation of knob, subtropics.

At present, the harvest machinery that China does not still have threshing-before-cutting comes into operation, and rice harves is mostly adopted and cut the way of afterwards taking off earlier, and operation is many, and labour intensity is big.A kind of fringe results machine of plucking is arranged abroad, take off the big China's national situation that is not suitable for of workload again because of not gathering in the crops cane and disconnected fringe simultaneously.

The purpose of this utility model just provides that a kind of spatter loss is few, adaptability is strong, adopt threshing-before-cutting technology, and the front passing-out type paddy rice that can reduce labor intensity is greatly cut off line.

Of the present utility model cut off line by running gear, cut take off part, bearing part three parts and engine, clutch and control lever thereof are formed, are characterized in cutting taking off partly placing before the running gear, the bearing part places after the running gear.The setting height(from bottom) of threshing cylinder and spike of rice height adapt to, and its rotation direction makes threshing zone below cylinder, and the grain of taking off enters the bearing part towards the back lower place.

Describe content of the present utility model and specific embodiments in detail below in conjunction with description of drawings:

Fig. 1 is a front view of the present utility model.

Fig. 2 is a vertical view of the present utility model.

Fig. 3 is the schematic diagram of expression sickle knife structure.

Fig. 4 is the schematic diagram of expression threshing part height adjustment mechanism structure.

As shown in Figure 1, the utility model takes off part, bearing part, running gear and engine (15), clutch and control lever (13) thereof and forms by cutting.Running gear comprises decelerator (10), driving wheel (12), direction handrail (16); The bearing part comprises hull (14), two tail wheels (17), driver's seat (20); Cut to take off and partly comprise threshing cylinder (4), straw shift wheel (1) and cutter etc.Described cutter is for stirring wheeled cutter, form (referring to accompanying drawing 3) by the sawtooth blade (22) that stirs wheel (7), comb-tooth-type clamper (21) and be contained in clamper (21) rear portion, screw feeder had both played the sickle section effect, played the effect of lateral transfer rice bar again.For being fed threshing cylinder effectively, spike of rice carries out threshing, can work simultaneously to derive, take off again splashproof, located lateral again, the utility model is in the front lower place of threshing cylinder (4), and the back lower place of straw shift wheel (1) adds the tooth-like derivation wheel of bow (3), and its rotation direction is opposite with threshing cylinder.And threshing cylinder (4), straw shift wheel (1) stir wheel (7), derive wheel (3) by a sealing belt transferring power.Dial the standing grain effect for straw shift wheel (1) can be played effectively, according to the characteristic of grain husk, this straw shift wheel (1) is the outer cylindrical drum that is surrounded by cavernous body, and ductor (2) is housed between straw shift wheel (1) and threshing cylinder.

Take off in order to be suitable for cutting of differing heights paddy, the utility model has disposed threshing part height adjustment mechanism (referring to Fig. 4), it is enclosed within the adjusting rod (19) on the decelerator high speed gear shaft (9), the stop gear (23) that is fixed on the machine by regulating wheel (5), sky, is fixed on lock pawl (24) and spring (25) and lock pawl release backguy (26) composition on the adjusting rod (19).In the utility model, cut to take off and all adopt the quick-release hanging lock type to connect between part, running gear, the bearing part three parts.Nearside divider (6) is housed in the front portion of originally cutting off line.

The course of work of the present utility model is summarized as follows: the clutch that closes, driving wheel (12) walking, is derived wheel (3), is stirred wheel (7) and rotatablely move accordingly simultaneously at threshing cylinder (4), straw shift wheel (1).Straw shift wheel (1) dials spike of rice to ductor (2), because machine moves ahead and bends the acting in conjunction that tooth is derived wheel (3), spike of rice enters the threshing zone of threshing cylinder (4), the grain of taking off be because the effect of inertia and gravity will enter feeder (11) (as accompanying drawing 1) along the tangential direction of threshing cylinder (4), and roll into hull (14).Cane after quilt takes off treats that with follow-up the motion of shelling fringe makes it be close to the upward also surperficial extraction of edge derivation wheel (3) of derivation wheel (3) by moving ahead of machine, the extraction amount reaches to a certain degree cane bottom, back and stirs wheel (7) and contact, stirring wheel (7) will make cane make horizontal compound motion rapidly, and under the acting in conjunction of sawtooth blade (22) that is fixed in comb-tooth-type clamper (21) rear portion and screw feeder blade periphery, cane is cut off, and is laterally pushed and throws to along tier pole groove (8) then and cut off line side field (having cut the district).

The utlity model has following advantage: 1. because adopting threshing-before-cutting technology, simple in structure, power consumption is little; 2. derive wheel and threshing Partial Height governor motion because being provided with the bow tooth formula, applicable cutting taken off differing heights and lodged uneven crop; 3. lake region deep mud farmland operation (hull (14) carrying) can be suitable for, working on farm land (tail wheel (17) carrying) can also be suitable for. 4. quick release is three parts, assembles also rapidly easyly, and good by performance, convenient in carrying is specially adapted to mountain area, hills area little field operation. 5. the utility model separates combination a little, also can do rural area short-distance transport and agricultural byproducts processing.
