Abstract

The utility model relates to a wheat harvester without cutting, which can be arranged in the front of a tractor. A feeding wheel of an adhesive tape lifter of the utility model and a threshing roller are arranged in a triangular position, the lower part of the roller is provided with a concave plate, and a doffer is provided with a transmission sieve on the lower part of the concave plate between the feeding wheel and the doffer. The lower part is a grain storage box and a blower fan, wheatear is fed to the threshing roller by the lifter, the wheatear is impacted at high speed and kneaded under the matching of the concave plate, and seeds are threshed. The seeds are engulfed into the doffer from a movable sieve and are threshed for the second time, bran husks and the waste residual are blown out, and the seeds all fall into the grain storage box.

Description

Cuttingless harvester for wheat

The utility model relates to a grow wheat and exempts to cut reaping machine, belongs to the technical field of agricultural machinery.

Present various grain header all is to be the product that pattern is developed with large-scale combine, its complex structure, power consumption is big, can not be used with the widely used middle-size and small-size tractor in rural area, therefore needs the needs that a kind of small-sized reaping machine can adapt to the rural area badly.

The purpose of this utility model is to provide a grow wheat to exempt to cut reaping machine, and it can overcome above-mentioned deficiency, can be used with small tractor.

The purpose of this utility model is to realize like this, install adhesive tape grain lifter threshing cylinder and feeding-wheel triangularity position, there is notch board the cylinder below, the notch board below is a doffer, its below is bolter and grain storage box, the band tooth adhesive tape of grain lifter is toppled over the wheat standing grain and is entered cylinder and feeding-wheel edge, be subjected to after utilizing cylinder and notch board mating reaction that the wheat head is involved in impacting and rub seed and fall into grain storage box, and wheat is carried out its wheat head of threshing second time by doffer and mixes and surplusly blown out outside the machine by blower fan finally through bolter.

Fig. 1 wheat exempts to cut the schematic diagram of reaping machine.

Now the structure of in conjunction with the accompanying drawings wheat being exempted to cut reaping machine is described in detail.

By Fig. 1, adhesive tape grain lifter (1) and feeding-wheel (2) threshing cylinder (3) are mutually the assembling of leg-of-mutton position, adhesive tape grain lifter (1) has 2 different standing grain of holding up of diameter to take turns (9) (10), by holding up standing grain adhesive tape (11) to be connected, there is evenly distributed straight-tooth (12) on the surface of adhesive tape (10), threshing cylinder (3) is that a circular drum is installed on the axle (13), there is a guard shield (14) cylinder (3) top, this guard shield (14) links to each other with frame (15), there is a notch board (4) cylinder (3) below, there is row's round roller shape double wedge on the notch board surface, double wedge becomes circular-arc arrangement, in the below of notch board (4) doffer (7) is housed, doffer (7) is contained on the axle (16), the double wedge left end is equipped with feeding-wheel (2), between feeding-wheel (2) and the doffer (7) portable screen (5) is housed, and its below is grain storage box (6) and blower fan (8).

Whole reaping machine is contained in the front of tractor, the speed rotation that adhesive tape grain lifter (1) is advanced to be higher than unit during work, plant is pressed into sweptback state, thereby the edge that is transported to feeding-wheel (2) and threshing cylinder (3) is under feeding-wheel (2) rotation relative with threshing cylinder (3), the wheat head just is involved in, under the mating reaction of threshing cylinder (3) and notch board (4), being subjected to high-speed impact rubs, fall on the following portable screen (5) in seed and assorted surplus process notch board (4) space, the doffer (7) that surplus grain on the sieve is involved in the sieve back carries out the threshing second time, seed and sugared shell are assorted surplus in the process that falls into the grain storage box (6) under the sieve, and sugared shell and the assorted surplus following blower fan (8) of grain storage box (6) that is installed in blow out outside the machine.

Compared with prior art, Cuttingless harvester for wheat has following advantages:

1, simple in structure, be easy to make, cost is also low.

2, power drain is few, and operating efficiency is higher.

3, can cooperate with existing small tractor.

4, easy to maintenance.

Claims

1, a grow wheat exempts to cut reaping machine and it is characterized in that the assembling of adhesive tape grain lifter (1) and feeding-wheel (2) threshing cylinder (3) triangularity position, cylinder (3) below has a notch board (4) notch board surface that the garden rod double wedge of one row's garden arc shooting is arranged, notch board (4) below has between a doffer (7) feeding-wheel (2) and the doffer (7) in addition is equipped with portable screen (5), and its below is grain storage box and blower fan (8).

2, reaping machine according to claim 1 is characterized in that adhesive tape grain lifter (1) has 2 different standing grain wheel (9) (10) of holding up of diameter to be connected with adhesive tape (11), and there is straight-tooth arranged in a uniform (12) on adhesive tape (11) surface.
