The harvest transferred to the chain conveyor 140 separates the grain from the stem while passing through the threshing unit 150.

At this time, the threshing unit 150 is provided with a rotating drum having a plurality of sharp teeth (扱 齒) on the cylindrical surface. The plunging of the rotating drum hits the grain of the harvest and falls, and the fallen grain falls to the lower sorting unit 160, and the stem after threshing is discharged to the rear of the gas 110.

The grains threshed in the threshing unit 150 are dropped to the sorting unit 160 to separate the hell or straw and discharged to the rear of the gas, and the grains are transferred to and stored in the storage tank formed at one side of the threshing unit 150. .

The sorting unit 160 is provided with a swinging shelf 161 which swings in the front and rear direction so that the grain falls to the lower side and performs a "weighting sorting" so that a hell, a straw, etc. are conveyed to the rear.

In addition, in addition to the sorting operation by the swing shelf 161 to generate a sorting wind from the tuyere 163 disposed in the lower portion of the swinging shelf 161, the sorting wind is blown to the lower swing shelf 161 In addition, wind sorting should be carried out.

The sorting tube 162 below the swing shelf 161 is provided with a tuyere 163, a first transfer part 165, and a second transfer part 167 in order from the front.

At this time, the first transfer unit 165 serves to convey the primary sorted grains falling from the swinging shelf 161 to the storage tank, the grains by using a transfer screw that is rolled on the bottom of the sorting barrel 162. It is collected to one side and pumped to the storage tank side.

In addition, the second conveying unit 167 reduces and conveys the stem-type grains selected by the sorting wind from the primary sorting grains to the threshing unit in front of the threshing unit using a reducing conveyor in the form of a conveying screw which is rolled out on the bottom of the sorting tube 162. It will play a role.

At this time, the tuyere 163, the first transfer unit 165, the second transfer unit 167 of the sorting unit 160 is driven by receiving the rotational power from the engine, each time of the sorting unit 160 as described above Pulley driving unit 170 for transmitting the engine power to the whole is installed on the side of the gas (110).

The pulley driving unit 170 is positioned below the side chain conveyor 140 of the body 110, and a plurality of pulleys for driving the respective rotating bodies 163, 165, and 167 of the sorting unit 160. 175, 177, and 179 are axially coupled, and each pulley 175, 177, and 179 are connected using the engine pulley 171 and the drive belt 173 to receive rotational power.

3, the pulley driving unit 170 is connected to the engine pulley 171 and the driving belt 173, the first pulley 175 receives the rotational power and transmits to the rotation shaft of the tuyere 163, The second pulley 177 is connected to the engine pulley 171 and the drive belt 173 and receives the rotational power and transmits it to the rotation shaft of the first transfer unit 165, and the second pulley 177 and the drive belt. It is connected to the (173) is composed of a third pulley 179 to receive the rotational power transmitted to the rotating shaft of the second transfer unit (167).

In this case, the pulley driving unit 170 and the chain conveyor 140 side is separated by a space using a cover, but the gum light or rice straw penetrates into the area of the pulley driving unit 170 through the gap.

Therefore, according to the present invention, by installing the gum light removing means 180 that is operated in conjunction with the pulley rotation shaft in the pulley driving unit 170, rice straw or gum light penetrating into the pulley driving unit 170 can be discharged to the outside without stagnation. Make sure

The gum removal means 180 is any one of a plurality of pulleys constituting the pulley driving unit 170, that is, the first pulley 175, the second pulley 177, the third pulley 179 as shown in FIG. It can be coupled directly to any one of the pulley rotation axis.

The gum light removing means 180 is composed of a shaft coupling body 181 coupled to the rotating shaft of the pulley, and a plurality of rakes 183 formed around the shaft coupling body 181 in the circumferential direction.

The rake portion 183 is preferably formed of 2 to 4 as shown in FIG. 3 and 4 show an example in which three rake portions 183 are formed.

Rake portion 183 as described above is preferably to be equally spaced, it can be manufactured integrally with the axial coupling body 181.

At this time, when the rake part 183 rotates together with the pulley, a collision may occur with a peripheral accessory or a foreign material in the pulley driving unit 170 such as rice straw or tree branches, and the elastic deformation may be flexibly handled in such a collision situation. It is desirable to be made of possible materials. Thus, the gum light removing means 180 may be manufactured integrally with the shaft coupling body 181 and the rake part 183 using a rubber material.

Figure 6 is a side view showing another embodiment of the gum removal means according to the present invention, the gum removal means 180 as shown in the drawing is an extension portion (part) opposite to the rotational direction of the rake portion 183 185 may be formed to generate rotational wind when the pulley is rotated. This rotational wind is discharged to the outside to prevent stagnant straw or gumfire in the pulley drive unit 170.

Gumbu removal means 180 of the present invention having the configuration as described above is made of a structure that is easily bolted to the existing pulley rotation shaft, there is an advantage that the installation and maintenance is convenient.

In addition, by being coupled to the rotating shaft of the pulley to rotate together, it is not necessary to provide a separate power source, by preventing foreign matters such as rice straw or gum light introduced into the pulley driving unit 170 to accumulate around the pulley and the driving belt, It is possible to omit the black flame elimination work performed, and to prevent the risk of fire due to frictional heat generation.
