Description

Combine {Combine}

The present invention relates to a combine that can control the amount of foreign matter discharged in proportion to the amount of foreign matter generated when cutting and transporting crops.

A combine is an agricultural machine that performs cutting operations to cut crops such as rice, barley, wheat, and soybeans, transfer operations to transport the cut crops, and threshing operations to thresh the transferred crops.

The combine combines the crop produced by threshing the threshing portion for threshing the crop, the feeder for transferring the cut crop to the inside of the chassis, the threshing part for threshing the crops carried through the feeder, and the threshing part. And a storage unit for sorting and storing.

The combine is divided into a self-type type (head-feed) combine and a normal type, and the self-type combine combines only the ear of the cut crop to the threshing part and threshes it, whereas the normal type is threshed. The combine is threshed by putting the cut crop directly into the threshing section.

During the cutting and transportation of crops, foreign matter, including dust and gumball, is generated. However, if the foreign matter is accumulated on the feeder, the crops may not be transported smoothly, so a suction fan is installed on one side of the feeder, and the foreign matter inside the feeder is sucked using the suction fan, and then discharged to the outside of the feeder.

Foreign matter inside the feeder depends on the working conditions and the surrounding environment.

However, the conventional combiner has a disadvantage in that the harvesting efficiency of the crop is lowered because the suction fan rotates at a predetermined rotational speed regardless of the amount of foreign substances in the feeder.

An object of the present invention may be to provide a combine that can solve all the problems of the prior art as described above.

Another object of the present invention, by varying the rotational speed of the discharge fan of the discharge portion for sucking and discharging foreign matter according to the amount of foreign matter in the feeder (Feeder) to which the crop is transferred, combine to improve the harvesting efficiency of the crop It can be provided.

Another object of the present invention, by adjusting the rotational speed of the dustproof screen to collect foreign substances contained in the cooling air supplied to the radiator side according to the rotational speed of the exhaust fan of the discharge portion, to secure the heater balance (Heat Balance) of the engine It may be to provide a combine that can be done.

The combine according to the invention, the chassis (車臺); It is installed on the front side of the undercarriage cutting unit for cutting crops; Threshing unit installed on the chassis and threshing the cut crops; A feeder installed between the harvesting portion and the threshing portion to transfer the cut crop to the threshing portion; It is installed on one side of the feeder and includes a discharge portion that sucks foreign substances inside the feeder and discharges it to the outside, and the amount of foreign substances discharged through the discharge portion may be proportional to the amount of foreign substances inside the feeder.

In the combine according to the embodiment of the present invention, the rotation speed of the discharge fan of the discharge portion for discharging foreign substances inside the feeder is variable in proportion to the amount of foreign substances inside the feeder, which is a feed path for the crops cut at the harvesting section. . Then, since clogging or damage to the feeder is prevented, there may be an effect of improving the harvesting efficiency of the crop.

In addition, the rotational speed or rotational cycle of the anti-vibration screen for collecting foreign substances contained in the cooling air supplied to the radiator side is proportional to the rotational speed of the discharge fan of the discharge unit. Then, the amount of cooling air flowing into the radiator side can be adjusted. Therefore, there may be an effect that the heater balance of the engine is secured.

The removal member 137 may be provided in a bar shape, and a brush or the like in contact with the anti-vibration screen 135 may be formed on a surface facing the anti-vibration screen 135. Since the anti-vibration screen 135 rotates and the removal member 137 is fixed, when the anti-vibration screen 135 rotates, foreign matter collected in the anti-vibration screen 135 is removed by the removal member 137. The anti-vibration screen 135 may rotate by driving the motor.

On the front side of the undercarriage 110, a cutting unit 140 for cutting a stem or the like of the crop may be installed. The harvesting unit 140 may include a reel unit for collecting crops by erecting crops, and a cutting unit for cutting crops.

For transporting the crops cut from the harvesting section 140 to the threshing section 171 installed in the chassis 110 to the part of the rear side undercarriage 110 of the cutting section 140, that is, the other side of the front side of the undercarriage 110. A feeder 150 may be installed. In addition, a threshing portion 171 for threshing the crops conveyed through the feeder 150 may be installed at the rear side undercarriage 110 of the feeder 150. That is, the feeder 150 is installed between the harvesting unit 140 and the threshing unit 171 to transfer the crops cut by the harvesting unit 140 to the threshing unit 171.

A storage unit 175 for selecting and storing grains generated by threshing in the threshing unit 171 may be installed on the rear side of the cab 120.

A driving unit 180 that receives and receives the power generated by the engine 131 may be installed under the chassis 110. The driving unit 180 may contact the ground and support the chassis 110 spaced apart from the ground, and may be provided as a caterpillar.

The feeder 150 will be described in detail.

The feeder 150 may include a duct 151 and a conveyor installed inside the duct 151 forming a transport path for cut grains having a predetermined length, and the conveyor is powered from the engine 131. Can receive and drive.

The front plate and the rear plate of the duct 151 may be opened. The opened front side of the duct 151 may be in communication with the cutting unit 140 side and the cut grain may be introduced, and the opened rear side may be communicated with the threshing portion 171 side to discharge the cut grain.

When the crop cut by the cutting unit 140 is transported through the feeder 150, a large amount of foreign matter, including dust and geombul, is accumulated in the feeder 150. Foreign matter accumulated in the feeder 150 may damage the feeder 150 and may prevent the transfer of the cut foreign matter. Therefore, the foreign matter inside the feeder 150 must be removed so that the foreign matter does not accumulate on the feeder 150.

Combine according to an embodiment of the present invention may include a discharge unit 160 for removing foreign matter inside the feeder 150, the discharge unit 160 is the duct of the feeder 150 on the cutting unit 140 side It may be installed on the upper portion of (151).

The discharge unit 160 may include a discharge fan 161, a motor 163, and a guide member 165.

The discharge fan 161 is located in the discharge hole 151a formed on the upper surface of the duct 151 of the feeder 150 to suck foreign substances inside the feeder 150 to the outside of the feeder 150 and discharge it. 163 may rotate the discharge fan 161. The reason for forming the discharge hole 151a on the upper surface of the feeder 150 is to prevent the grains inside the feeder 150 from being discharged through the discharge hole 151a.

The guide member 165 may be installed on the feeder 150 in a form in which the upper portion surrounds the discharge hole 151a, and the lower surface may be opened to face the ground. At this time, it is natural that the inside of the upper portion of the guide member 165 communicates with the discharge hole 151a. Thus, the foreign material introduced into the upper portion through the discharge hole 151a into the guide member 165 flows along the side surface of the guide member 165 and is discharged downward.

The motor 163 may be installed in the guide member 165 or may be installed in the feeder 150 portion outside the discharge hole 151a, and may be driven by receiving power from a separately provided battery or engine 131.

The amount of foreign matter inside the feeder 150 varies greatly depending on the yield of the crop or the dry state of the crop. Therefore, the amount of foreign matter discharged to the outside of the feeder 150 should also be adjusted according to the amount of foreign matter inside the feeder 150.

The combine according to an embodiment of the present invention can control the amount of foreign matter discharged to the outside of the feeder 150 according to the amount of foreign matter inside the feeder 150.

The amount of foreign matter discharged to the outside of the feeder 150 may be controlled by adjusting the rotation speed of the discharge fan 161 of the discharge unit 160. More specifically, if a large amount of foreign matter exists in the feeder 150, the exhaust fan 161 is rotated at a high speed, and when a small amount of foreign matter exists in the feeder 150, the exhaust fan 161 is slow. Can be rotated. That is, the rotation speed of the discharge fan 161 may be varied in proportion to the amount of foreign matter inside the feeder 150 by the control unit 190.

Combine according to an embodiment of the present invention can measure the amount of foreign matter inside the feeder 150 using the amount of the crop or the dryness of the crop that flows into the feeder 150. That is, if the amount of cut crops flowing into the feeder 150 is large, or if the dryness of the crop is high, a large amount of foreign matter is generated, so the amount of cut crops flowing into the feeder 150 or drying of the crops The rotation speed of the discharge fan 161 can be adjusted in proportion to the figure.

The combine according to an embodiment of the present invention may measure the amount of foreign matter inside the feeder 150 using the amount of dust. That is, if there is a large amount of dust in the feeder 150, there is a large amount of foreign matter. Therefore, the rotation speed of the discharge fan 161 can be adjusted in proportion to the amount of dust measured inside the feeder 150.

The discharge unit 160 of the combiner according to an embodiment of the present invention measures the amount of cut crops flowing into the feeder 150, measures the dryness of the crops, or the amount of foreign matter inside the feeder 150. Or a sensor 167 for measuring the amount of dust inside the feeder 150. In addition, the combine according to an embodiment of the present invention may include the above-described control unit 190 for receiving the signal from the sensor 167 and adjusting the rotation speed of the discharge fan 161.

The rotation speed of the motor 163 for rotating the discharge fan 161 and the rotation speed and rotation cycle of the motor for the anti-vibration screen 135 can be controlled by the controller 190, and the controller 190 is a motor 163 The rotational speed and the rotational speed and rotational cycle of the motor for the anti-vibration screen 135 can be controlled proportionally. That is, if the amount of foreign matter inside the feeder 150 detected by the sensor 167 is large, the rotation speed of the motor 163 is increased, and a large amount of foreign matter is also collected on the anti-vibration screen 135. The rotation speed and rotation period of the motor for the screen 135 may be increased.

The combine according to an embodiment of the present invention may allow a large amount of cooling air to be introduced into the radiator 132 side so that the engine 131 can be cooled quickly when the temperature becomes high.

In detail, the dust screen 135 may be rotatably installed in the inlet 130a of the engine compartment 130, and the dust screen 135 is used for cooling supplied to the radiator 132 through the inlet 130a. It can collect foreign substances contained in the air.

In addition, a removal member 137 for removing foreign substances collected on the dustproof screen 135 may be fixedly installed on the side surface of the engine compartment 131. The removal member 137 may be provided in a bar shape, and a brush or the like in contact with the anti-vibration screen 135 may be formed on a surface facing the anti-vibration screen 135. Since the anti-vibration screen 135 rotates and the removal member 137 is fixed, when the anti-vibration screen 135 rotates, foreign matter collected in the anti-vibration screen 135 is removed by the removal member 137.

Then, since the foreign matter collected in the dustproof screen 135 has been removed, a large amount of cooling air may pass through the dustproof screen 135 and flow into the radiator 132, whereby the cooling water of the radiator 132 It can be cooled to a relatively lower temperature. Therefore, since the cooling efficiency of the engine 131 is improved, a heater balance of the engine 131 can be secured.

The anti-vibration screen 135 rotatably installed may repeat rotation and stop at a predetermined cycle. At this time, the rotation cycle of the anti-vibration screen 135 may be proportional to the rotation speed of the discharge fan 161. That is, if the discharge fan 161 rotates at a low speed. The rotation cycle of the anti-vibration screen 135 may be long, and when the discharge fan 161 rotates at a high speed, the rotation cycle of the anti-vibration screen 135 may be short. If the rotation cycle of the anti-vibration screen 135 is long, the degree of removal of foreign matter collected on the anti-vibration screen 135 is relatively low, and when the rotation cycle of the anti-vibration screen 135 is short, the dust is collected on the anti-vibration screen 135. It is natural that the degree of removal of foreign matter is relatively high.

When the anti-vibration screen 135 repeats rotation → stop → rotation → stop, each rotation time of the anti-vibration screen 135 may be longer than each stop time. For example, the anti-vibration screen 135 may have a cycle of 5 seconds stop → 10 seconds rotation → 5 seconds stop → 10 seconds rotation.

And, the rotational speed and rotational cycle of the anti-vibration screen 135 may increase or decrease the rotational speed depending on the amount of foreign matter, and may shorten or lengthen the rotational cycle, and may have a shorter stop time than the rotational time. It can be long. In addition, in some cases, the anti-vibration screen 135 may be rotated at all times.

Combine according to an embodiment of the present invention, the discharge fan 161 of the discharge unit 160 for discharging the foreign matter inside the feeder 150 in proportion to the amount of foreign matter inside the feeder 150, the transport passage of the crop The rotation speed is variable. Then, clogging or damage of the feeder 150 is prevented, so that the harvesting efficiency of the crop can be improved.

And, the rotational speed or rotational cycle of the anti-vibration screen 135 that collects foreign substances contained in the cooling air supplied to the radiator 132 side is proportional to the rotational speed of the discharge fan 161. Then, the amount of cooling air flowing into the radiator 132 may be adjusted. Therefore, a heater balance of the engine 131 can be secured.
