Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reaping harvester such as a combine.

As shown in Figure 1, general reaping and harvesting work forms include a row cutting process in which the crop is harvested along the planted grain culm line, and a horizontal cutting process in which the crop is harvested in a direction perpendicular to the planted grain culm line. The first is the so-called rotary cutting operation, which is carried out continuously while turning the machine 90 degrees at the end of the row, and the second is the row-cutting operation along the planted grain culm rows on one side of the field, as shown in Figure 2. There are two types of work: the so-called reciprocating mowing work, in which the machine travels to the other side of the field and row-mows along the planted grain culm rows again.

Considering these two types of work, the former round mowing operation is a continuous work of row cutting and horizontal cutting, but it requires complicated turning of the machine to align the rows. , there is a certain amount of time loss on average due to the turning, and in the case of the latter reciprocating mowing work, there is no need for the time-consuming turning operation of the machine as in circular mowing work, and the loss due to turning is reduced. Although the time is short, there is a loss of time as the aircraft travels to the headland until the next row mowing area. Comparing the time losses in both of these forms, we find that the above-mentioned time loss during reciprocating mowing work is very large immediately after the start of work, but gradually decreases as the work progresses. Therefore, from the start of the work until the work has progressed to a certain point, circular mowing work has less loss time and is advantageous in terms of work efficiency, but after the work has progressed to a certain point, reciprocating mowing work is more effective. This reduces lost time and improves work efficiency compared to circular mowing.

The present invention, in view of the relative changes in loss time associated with the work history in both work types as described above, by rationally combining both work types,
It is an object of the present invention to provide a reaping/harvesting machine that can easily perform reaping and harvesting work with maximum efficiency by reducing the overall loss time as much as possible.

First, embodiments of the present invention will be described based on the drawings.

Figure 3 shows a combine harvester, in front of which is a machine consisting of a crawler-type traveling device 1 and a threshing device 2, a pulling device 3, a clipper-type reaping device 4, and a machine that gradually changes the posture of the harvested grain culm to a sideways posture. A reaping section 7 consisting of a vertical conveying device 6 that conveys and supplies threshing to the threshing feed chain 5 is disposed.

In such a combine harvester, as shown in Figure 4, during circular mowing work (see Figure 1), one side in the horizontal mowing direction perpendicular to the planted grain culm row, which gradually decreases as the work progresses. a mechanism 8 for detecting the actual reaping working distance L; and a mechanism 8 for detecting the actual reaping working distance L at
A mechanism 9 is provided for setting the lateral movement speed V of the machine body during reciprocating mowing work (see Fig. 2), and a calculation mechanism is provided for calculating the detected value from the detection mechanism 8 and the set value from the speed setting mechanism 9. Enter 10 and
It is configured to calculate the travel time T of the machine body during reciprocating mowing work at the actual mowing work distance L. In addition, the required machine turning time t ₁ at both ends of the horizontal cutting process during circular cutting work, the cumulative time T ₁ of t ₁
A mechanism 11 is provided for setting the turning time _T1 from the setting mechanism 11 and the required traveling time T from the calculation mechanism 10 are input to the comparison mechanism 12. When it is determined that the set turning time _T1 during mowing work is equal to or greater than the travel time T required during reciprocating mowing work, the indicator lamp 13, which is one of the required mechanisms provided in the control section, is activated. It is configured to turn on.

When the indicator lamp 13 is off, it indicates that circular mowing work is more efficient, and when it is lit, it indicates that reciprocating mowing work is more efficient.

The detection mechanism 8 calculates and detects the actual reaping work distance from the number of rotations of the final shaft or axle in the traveling transmission case, the amount of movement of the machine per one rotation, and the reaping travel time of the machine on one side. It is configured as much as possible.

Further, both the setting mechanisms 9 and 11 are configured to be freely changeable and set according to the operator's skill level, field conditions, and the like.

In the above-mentioned embodiment, an indicator lamp is used as the required mechanism 13, but a buzzer may be used in place of this, and a work mode switching mechanism that automatically switches from circular mowing work to reciprocating mowing work may be used. It is also good.

In the above embodiment, the detection mechanism 8, the speed setting mechanism 9, and the calculation mechanism 10 are collectively referred to as Also, the setting mechanism 11 is referred to as a time conversion means A for calculating the distance travel time, and the setting mechanism 11 is referred to as a turning time setting means for arbitrarily setting the time required for the machine turning operation at both ends of the horizontal cutting process accompanying the round cutting work, Furthermore, comparison mechanism 1
2 is referred to as a control means for comparing the time calculated by the time conversion means A and the time set by the turning time setting means 11 and outputting a signal indicating that the calculated time has become less than the set time, Furthermore, the required mechanism 13 is referred to as an alarm device.

In summary, the reaping harvester according to the present invention continuously performs work by alternately repeating the row cutting process along the stem culm rows and the horizontal cutting process proceeding in the direction crossing the stem culm rows. In a reaping harvester configured to selectively perform mowing work and reciprocating mowing work in which the work is performed while repeating only the row mowing process, the horizontal mowing process gradually decreases during the circular mowing process. A time conversion means A that calculates the same distance travel time when traveling on a headland in the reciprocating mowing process from the machine travel distance, and the time required for the machine turning operation at both ends of the side mowing process associated with the round mowing operation are arbitrarily set. a turning time setting means 11, and comparing the calculated time by the time conversion means A with the set time by the turning time setting means 11 to generate a signal that the calculated time has become less than the set time. , a control means 12 is provided which outputs an output to an alarm device or a work mode switching mechanism, so that when starting the work, the work starts from the round mowing mode and the progress of this round mowing work is controlled. Accordingly, by the time conversion means,
Detecting the travel time required for one side, which decreases as the work progresses, and that the detected value has reached the set value;
In other words, it detects that the time required to travel on one side, which decreases as the work progresses, has reached the time required for the machine to turn during mowing work, and alerts the operator to an alarm such as an indicator lamp or buzzer. Based on this, the work mode can be switched manually or automatically from circular mowing to reciprocating mowing, and the reaping work for one field can be changed to circular mowing. By using a rational combination of the reaping mode and the reciprocating mode, it has become possible to reduce the loss time as much as possible and to perform the reaping and harvesting operation with maximum efficiency as a whole.
