BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device for counter-

The present invention relates generally to a combine harvester, and more particularly, to a combine harvester which is constructed so as to solve the congestion of the harvester through reverse rotation in the case where congestion or clogging occurs in a feeder portion, To a pre-mounted reverse rotation device.

Generally, the normal type combine is also called a full feed type combine, and it can be said that it is constituted so as to obtain the whole grain through the threshing process in the inside of the threshing device by providing the entire cut interrupted portion inside the threshing device. The common type combine is generally constructed so as to concentrate a part of cuts cut at the preliminary part through a cut auger and then transfer the part to a threshing device through the inside of the feeder case.

If there is a large number of interrupted trains transported by the pre-loading unit in the ordinary combine, congestion or clogging easily occurs in the feeder case having a predetermined cross-sectional area. If such a stagnation occurs inside the feeder case, it will be closed to the vicinity of the cut auger. As a conventional technique for solving such a problem, Japanese Patent No. 5763457 proposes an apparatus for reversing a feed mechanism installed inside a feeder case to feed a gap.

However, in such a conventional technique, the drive sprocket provided inside the feeder case is mechanically reversed. For example, a gear box in which a large number of bevel gears are incorporated is installed for transmitting power in forward and reverse directions, and a forward clutch and a reverse clutch for interrupting the output from the gear box are respectively provided. Such a mechanical structure substantially increases the number of components, and various disadvantages due to a large number of bevel gears, a pair of clutches, and the like have been pointed out.

The present invention can be said to be a provision of an antistatic reversing device for solving stagnation occurring in the feeder case which feeds a cutaway portion cut in the antistatic portion.

Another object of the present invention is to provide a pre-rotation reversing device having the simplest structure using a motor and securing the driving and the operation stability as much as possible.

It is another object of the present invention to provide a pre-rotation reversing device in which no loss of power occurs in a power transmission process for reverse rotation.

According to an aspect of the present invention, there is provided a cutting machine comprising a cutter for cutting a crop, a cutting auger for concentrating the cutter cut by the cutter, a feeder casing for feeding the cutter by the cutting auger, An example of a normal type combine having a pair of drive sprockets and a driven sprocket to be installed, and a cutting input shaft for transmitting power to the drive sprocket; A transmitting means for transmitting the rotational force from the engine to the cutting input shaft in the normal rotation direction; A reverse rotation motor for rotating the cutting input shaft in a reverse rotation direction; A driving pinion coupled to an output shaft of the reverse rotation motor; A deceleration idle shaft provided with a deceleration container for engaging with the drive pinion and decelerating the number of revolutions; And a sprocket disposed on the reduction idle shaft and the cutting input shaft, respectively, to transmit the decelerated power from the deceleration idle shaft to the cutting input shaft using the chain. Here, the drive pinion can be engaged with the decelerating container or spaced apart at a predetermined interval, so that the power can be transmitted in the opposite direction only when the actual reverse rotation is performed.

According to the first embodiment, the drive pinion is configured so that the output shaft of the reverse rotation dedicated motor can be engaged with or spaced from the reduction gear unit by being reciprocally movable in the axial direction at a constant interval.

According to the second embodiment, the drive pinion is configured to be engaged with or spaced from the decelerating container by the whole of the reverse-rotation dedicated motor and the drive pinion assembly being moveable outwardly by a certain distance.

The normal-type combine reverse-rotation device according to the third embodiment further comprises a blocking means for blocking supply of electricity to the reverse-specific motor when the cut-off portion is driven in the normal direction.

According to the embodiment of the present invention, the cut-off lever sensor for detecting the movement or the position of the cutting lever installed on the driver's seat of the combine, and the cut- And a control unit.

According to the present invention having the above-described configuration, the following operational effects can be expected.

It can be understood that the congestion state can be easily solved by driving the reverse rotation motor when the congestion of the interstices occurs in the feeder case because the amount of the interstices to be cut at the preliminary mounting portion and transferred to the inside of the feeder casing is large.

In the present invention, the rotational force of the reverse rotation motor of the preliminary-stage reverse rotation device is sufficiently decelerated using a deceleration mechanism. The deceleration mechanism is composed of, for example, a pair of sprockets using a pair of gears and a chain . In the deceleration mechanism of the present invention, since the transmission of the power is accurate, the idling phenomenon does not occur, and the reliability of the solution of the substantially stagnated groove will be high.

Further, according to the present invention, in a state in which the reverse rotation function is not used, the supply of electric power to the reverse rotation dedicated motor is completely blocked, thereby ensuring more accurate operation reliability.

3 is a block diagram exemplarily showing the control of the reverse rotation motor of the present invention.

Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. First, as shown in FIG. 1, the cutting input shaft 10 of the present invention can be regarded as an axis for transmitting the driving force transmitted from the engine to the feeder 20 and the preload unit 100. Here, the power transmission from the engine to the cutting input shaft 10 may have various embodiments, so that a detailed description of these various embodiments will be omitted.

1, the driving force of the engine is transmitted to the counter shaft, and the power of the counter shaft is transmitted to the pulley of the counter shaft and the belt caught by the pulley 46 of the input shaft 32 of the thresher case 30 And is transmitted to the thresher case input shaft 32 through the throttle case. Power is also transmitted between the thresher case input shaft 32 and the cutting input shaft 10 by the belt engaged with the pulleys 14 and 34.

Such power transmission is merely an example, and it goes without saying that there may be various embodiments of the power transmission to the cutting input shaft 10. The cutting input shaft 10 transmits power to the preload unit 100 through a cutting input shaft sprocket 16 provided at the opposite end.

The power of the cutting input shaft 10 is transmitted to the rotary shaft 110a of the laquer 110, the rotary shaft 112a of the cut auger 112 and the cutting blade 114 using a plurality of sprockets and chains Power is transmitted. In the combine, the preload unit 100 includes a laquer 110, a cut auger 112, and a cutting unit 114. Various arrangements for transmitting power using the chain and the sprocket in each of these units include various It should be understood that there may be embodiments of the form. In the present invention, it is natural that the power transmission structure to the components 110, 112, and 114 of the preload unit 100 on the cutting input shaft 10 can not be limited to such a form.

Referring back to FIG. 1, as described above, the cutting force of the engine is transmitted to the cutting input shaft 10 in one direction. Hereinafter, the rotation direction of the cutting input shaft 10 in one direction, that is, the direction in which the preload unit 100 can be normally driven will be referred to as a forward rotation direction or abbreviated as a forward direction in the following description. In the present invention, a reverse rotation dedicated motor (50) capable of reversing the cutting input shaft (10) is provided. This reverse-rotation-dedicated motor 50 is for substantially reversing the drive sprocket 24 inside the feeder 20.

The feeder 20 is a portion for conveying a concentrated cutaway section through the cut auger 112. In this feeder 20, a pair of drive sprockets 24 and a driven sprocket 26 are provided inside the feeder case 22. [ A plurality of plates provided in the chain connecting the drive sprocket 24 and the driven sprocket 26 are transferred to the inside of the feeder case 22.

If the amount of the interstices is excessively introduced, congestion occurs in the feeder case. When the stagnation occurs, the driving sprocket 24 needs to be rotated in the reverse direction because it can not be transported by virtue of the rotational force of the cutting input shaft 10. For this purpose, the cutting input shaft 10 must rotate in the reverse direction.

In order to reverse the rotation of the cutting input shaft 10, the reverse rotation dedicated motor 50 is provided in the present invention. The reverse rotation dedicated motor 50 must rotate the cutting input shaft 10 in a reverse direction through a sufficiently reduced number of revolutions. To this end, it is preferable to use a drive pinion 54 integrally assembled to the output shaft 52 of the reverse rotation dedicated motor 50. [

The drive pinion 54 can transmit power to the cutting input shaft 10 via the reduction gear or reduction mechanism 58, 60, 62. The deceleration mechanism includes a deceleration idle shaft 60 and a decelerating vessel 58 coupled to the decelerating idle shaft and engageable with the driving pinion 54. The decelerating vessel 58 is coupled to the decelerating idle shaft 60, And a drive sprocket 62 rotated by a gear 58. The driven sprocket 12 connected to the drive sprocket 62 and provided on the cut input shaft 10 forms a part of the deceleration mechanism by significantly increasing the size of the driven sprocket 62 than the drive sprocket 62.

Of course, the reduction gear unit 58 employs a large gear having a larger number of teeth than the drive pinion 54, so that a sufficient reduction ratio can be obtained even by the drive pinion 54 and the reduction gear unit 58. [ By transmitting the deceleration mechanism in this way, the rotation speed of the reverse rotation dedicated motor 50 can be transmitted to the preliminary input shaft 10 with a torque having a large torque while being sufficiently decelerated.

In the embodiment shown in Fig. 1, the deceleration mechanism uses a pair of gears 54 and 58 engaged with each other and a pair of sprockets 12 and 62 engaged with the chain. Thus, the power transmission using the chain and the gear may be advantageous in that virtually no idle phenomenon occurs. However, in the present invention, it is natural that power transmission using pulleys and belts is also possible in place of the sprockets 12, 62 described above.

However, in the power transmission structure in which the output from the reverse-rotation dedicated motor 50 is decelerated and transmitted to the cut-off input shaft 10 as in the illustrated embodiment, the pair of gears 54, 58 and the pair of sprockets 12 , 62 and a chain, it is expected that it is preferable to configure such that the phenomenon of idle is prevented. The number of teeth and the like of the gear and the sprocket used in the deceleration mechanism in the present invention need to be decided so that the gear and the sprocket used for the deceleration mechanism in the present invention can be most effectively stagnated in the reverse rotation of the cutting input shaft 10.

Here, it can be said that the drive pinion 54 and the reduction container 58 provided on the output shaft 52 of the reverse rotation dedicated motor 50 are preferably engaged with each other only at the time of actual driving. In the embodiment shown in FIG. 2, the reverse rotation drive unit is constituted by a starter motor assembly in which the drive pinion 54 can be moved a certain distance in the axial direction by the output shaft 52 of the deceleration motor 50. That is, in the illustrated embodiment, the reverse rotation drive unit for rotating the cutting input shaft 10 in the reverse direction includes a reverse rotation dedicated motor 50, A starter motor assembly composed of an output shaft 52 that moves in an interval is used, and a drive pinion 54 is provided at an end of the output shaft.

When the reverse rotation drive unit is constructed by the starter motor assembly as described above, the drive pinion 54 advances to engage with the reduction gear unit 58 during reverse rotation, as shown in FIG. The decelerating container 58 rotates the cutting input shaft 10 in a reverse direction so that the drive sprocket 24 and the driven sprocket 26 of the feeder 20 are also rotated in the reverse direction. By this reverse rotation, the interstices stagnated inside the feeder case 22 are reversed to the side of the cut auger 112 of the preliminary part.

By this operation, the interstices stagnated in the feeder case 22 are moved to the inlet portion of the feeder case 22, and when the operation is continued for a predetermined time, the substantial congestion is resolved, It will be possible to return to a state in which normal operation is possible.

In the embodiment shown in Figs. 1 and 3A, the drive pinion 54 of the reverse-rotation dedicated motor 50 is moved in the axial direction and meshed with the decelerating container fish 58. However, in addition to the movement of the drive pinion 54 of the reverse rotation dedicated motor 50 in the direction of the output shaft 52, the reverse rotation dedicated motor 50 and the drive pinion 54 assembly are moved in the direction different from the output shaft 52 It is a matter of course that it is possible to reciprocate in a direction perpendicular to the output shaft.

In this embodiment, as shown in Fig. 3 (b), the drive pinion 54 and the reduction gear chamber 58 are arranged so as to be in line with each other. The motor 50 and the drive pinion assembly 54 are moved in the direction of the arrow by using a supporting structure such as a separate bracket (not shown) so as to be combined with or separated from the decelerating container 58 It will be possible.

The reverse rotation of the cutting input shaft 10 is also reversed in the same direction as the pre-rotation shaft which is substantially connected by a plurality of chains. 1, the cut-off input shaft 10 includes a plurality of sprockets and a chain, and the rotation axis 112a of the cut auger 112 and the rotation axis 110a of the cut- It can be seen that they are connected to each other. Accordingly, when the cutting input shaft 10 is rotated in the reverse direction by the reverse rotation driving unit, the rotation axis 112a of the cut auger 112 and the rotation axis 110a of the ray crest 110 naturally rotate reversely.

The reverse rotation of the laquer 110 is not significant, but the reverse rotation of the cut auger 112 substantially eliminates the stagnation of the interstices in the inlet portion of the feeder case 22, It can be seen that it has a significant meaning in the rotating device. Next, a description will be made as to whether or not the reverse rotation dedicated motor 50 is driven during the normal operation of the above-described preload portion (rotation of the cutting input shaft in the normal rotation direction).

The reverse rotation dedicated motor 50 does not need to be driven at the time of operation of the preload unit 100. [ Therefore, it is preferable to turn off the supply of electricity to the reverse-rotation dedicated motor 50 when the preload section 100 is driven in the forward direction. It may be said that it is preferable to provide means for detecting whether the preload unit 100 is in the current operation state and to control the reverse-rotation dedicated motor 50 accordingly.

4, a sensing sensor 150 for detecting the operation of the cutting lever installed in the vicinity of the driver's seat of the combine is installed, and the sensing value of the cutting lever sensing sensor 150 is transmitted to the controller 140, . The cutting lever sensing sensor 150 is a sensor capable of detecting the position or movement of the cutting lever. For example, when the cutting lever operated by a driver for cutting work is in a state of instructing a work, For example, a potentiometer or the like may be used for detecting whether or not it is in a pre-operation state.

In place of the cutting lever sensing sensor 150, a preliminary part rotation detection sensor 154 for detecting whether the rotary shaft of the preliminary installation part is driven may be installed, and the detected signal may be transmitted to the control part 140 It is possible. Here, the pre-placement rotation detection sensor 154 can detect the rotation of the pre-installation auger auger, and it is also possible to sense the rotation of the pre-installation portion of the layout. The rotation signal sensed by the preliminary rotation sensor 154 may be said to substantially mean that the cutter is normally operating, and such a signal is transmitted to the controller 140.

The control unit 140 in this embodiment controls the reverse rotation dedicated motor 50 based on the signals from the cutting lever detection sensor 150 or the preload rotation detection sensor 154, And controls the power supply to the reverse rotation dedicated motor 50 to shut off. For example, the switch of the electric line supplied to the reverse-rotation dedicated motor 50 is always controlled to be in the off-state, thereby completely preventing the undesired driving of the reverse-rotation dedicated motor 50.

As described above, according to the present invention, absolute power is not applied to the reverse-rotation dedicated motor 50 under the normal operation state of the pre-installation portion (the cutting input shaft rotates in the normal direction) Or when the drive lever is turned on, it is impossible to drive the reverse rotation dedicated motor 50.

In the embodiment shown in Fig. 4, the power supply to the reverse rotation dedicated motor 50 is cut off by using the control unit 140 of the ordinary combine. However, the present invention is not limited to this example. It is also possible to use one or a plurality of switching elements instead of the controller 140. For example, it is possible to provide a motor control switch in the electric supply line of the reverse rotation dedicated motor 50, and to configure such a motor control switch to interlock with the take-off lever.

Specifically, when the cutting lever installed on the driver's seat of the combine is operated in the ON state, the motor control switch may be turned off. It is also possible to configure the motor control switch to be in the OFF state by driving the rotary shaft of the preload part. As described above, the configuration for interlocking the motor control switch and the cutting lever or the configuration for interlocking the motor control switch and the preliminary rotary shaft can be configured to be physically (or mechanically) interlocked with each other, and a plurality of switching elements It is of course also possible to control using a microprocessor.
