Description

Grain threshing machine having a blade

The present invention relates to a threshing machine that separates the grain from the grain, and more specifically, the cutting blade having a double blade of the 'c' shape on the inner surface of the main body on which the blade fixing plate and the threshing drum are rotatably mounted. The present invention relates to a threshing machine in which the threshing drum rotates smoothly by preventing grains from being stacked between the threshing drum and the main body by finely cutting the stem and the ear of the grain to be threshed.

In general, the threshing machine is composed of a plurality of rows of threshing blades formed on the outer circumferential surface of the threshing drum, and in order to thresh the grain by such a threshing drum, the threshing drum is rotated and the ear of the grain is placed on the threshing drum rapidly rotating. The threshing blade formed on the outer circumferential surface of the threshing drum by contacting the grain portion of the grain cutting or hitting the grain to separate the grain and the grain from the stem.

The grains and spikes separated from the stem are scattered through the outlet and discharged outside the threshing machine due to the wind generated by the rotation of the threshing drum.

Grains discharged to the outside of the threshing machine are heavy and fall close to each other, while the ear is scattered over long distances, resulting in the selection of the ears and grains.

However, in the process of grain threshing, not only the ear part is cut, but also the stem part of the grain is also cut and discharged, and is sometimes discharged with the grain attached to the ear.

In such a case, the bulky stem and the grained ears discharged to the outside of the threshing machine do not fly due to the weight and are mixed with the grains.

In order to solve such a problem, in the related art, a dust control fan is installed on the outlet of the thresher so that the stem of the ear or grain which is not completely dropped can be suppressed from being discharged as it is.

1 is a side cross-sectional view showing a conventional sheller.

As shown in Figure 1, the threshing machine in the prior art threshing drum 100 is rotated by receiving power, threshing blade 110 is installed in a plurality of rows on the outer peripheral surface of the threshing drum 100, the threshing drum It is composed of a dust control amount 300 is installed on the outlet 400 of the upper portion (100).

The conventional threshing machine configured as described above retracts the dust control fan 300 when the grain is not completely separated from the ear in the process of threshing the grain from the grain, thereby reducing the size of the outlet 400 of the threshing machine. If the grain stem and the grain is attached to the large ears are not discharged as it is continuously rotated along the threshing drum (100) and the grains are separated completely and only the ears and stems of finely broken state discharged through the outlet (400) It is configured to facilitate screening and gumbu.

However, the threshing machine (open number 2000-12494) is a threshing drum because stems and spikes are stacked between the threshing drum 100 and the control fan 300 or between the threshing drum 100 and the main body 200. Problems of the efficiency that the rotational force of (100) could not be threshed due to the loss of efficiency, which is not uniformly distributed in all directions in the process of discharging finely crushed stems and ears due to the wind generated by the rotation of the threshing drum (100). There was this.

Therefore, the present invention was created in order to solve the above-mentioned shortcomings, and an object of the present invention is a cutting knife having a double blade having a 'c' shape on the inner curved surface of the main body on which the blade fixing plate and the threshing drum are rotatably mounted. By detachably fastening the stem and the ear of the grain to be threshed by installing the removable fastening to the holder with bolts and nuts to prevent the grain from being stacked between the threshing drum and the main body so that the threshing drum rotates smoothly. It is to provide a threshing machine that maximizes efficiency by inducing and discharging the cut stem and the ear in a predetermined direction by attaching a plurality of induction wings to the cutting knife.

According to the present invention in order to achieve the above object, the threshing machine is installed on the inner surface of the threshing drum rotatably mounted to the main body is formed in the inlet and outlet and the strainer, and the threshing drum is rotatably mounted A first cutting knife for finely cutting the grain stem and the ear of the grain, a second cutting knife for cutting the stem of the grain stacked between the threshing blade and the blade fixing plate installed in a plurality of rows on the outer periphery of the threshing drum, and the cut stem. And is characterized by consisting of the guide vane for induction discharge of the ear in a constant direction.

It is a perspective view of the twin blade a bound to the knife, Figure 7 is a plan view of the second blade of the threshing machine according to the present invention.

As shown, the threshing drum 20 is coupled to the body of the threshing machine to rotate in one direction by receiving the rotational force of the motor omitted in the drawing, the outer periphery of the threshing drum 20 to the ears and grains in the grain Multiple threshing blades 22 are formed to separate.

Meanwhile, the threshing drum 20 and the main body 10 during threshing are mounted by detachably attaching the first cutting knife 30 to the inner curved surface of the main body 10 which maintains a constant distance from the outer periphery of the threshing drum 20. It is configured to be discharged to the discharge port (B) through the through portion 34 formed between the twin blade a (31) of the first cutting knife 30 at the same time finely cut the stem flowing between the inner curved surface of the.

In addition, a second cutting knife having a plurality of 'c' shaped twin blades so as to cut and discharge the stem and the ear of a large volume which is not discharged through the outlet B as the bottom of the blade fixing plate 50 once again ( 40) and a plurality of guide vanes 42 are mounted.

Referring to the operation of the threshing machine having the configuration as described above as follows.

When the grain is introduced into the inlet (A) in a state in which the threshing drum 20 is rotated in one direction to thresh the grain attached to the ear of the grain by using the threshing machine according to the present invention, the threshing drum 20 is rotated. The grain moves to outlet B.

The grains are separated from the ear and discharged into the strainer 12 by the threshing blade 22 formed on the outer periphery of the threshing drum 20 while the grain is being moved to the outlet B. The stem of the grain is the main body. It cuts off by the 1st cutting knife 30 attached to (10), and is discharged | emitted through the discharge port B. As shown in FIG.

The large volume of stem and ear which is not discharged through the outlet B is again chopped by the second cutting knife 40 and discharged in a constant direction guided by the plurality of guide vanes 42.

According to the present invention described above, it is possible to minimize the loss of grain by preventing the grain is discharged in the state attached to the ear, and also the stem of the grain stacked between the threshing drum 20 and the main body 10 during threshing By using the first cutting knife 30, the second cutting knife 40 and the guide blade 42 is discharged in a constant direction induced by cutting finely, there is an effect of protecting the threshing machine from overload.
