Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mobile agricultural machine such as a combine harvester or a binder, and relates to the structure of a grouping and traveling operation system.

Some mobile agricultural machinery travel control systems include a main transmission that changes the traveling speed in multiple stages, including reverse travel, and an auxiliary transmission that further changes the traveling speed into two high and low stages.

Generally, this driving operation system has an operation mode in which the main transmission is shifted along an H-shaped guide groove, and the auxiliary transmission is shifted at two positions along a linear guide groove.

Considering the speed change operation using this driving operation system, when driving on the road, there are few reverse switching operations, and most of the time the speed change is performed by operating only the main transmission, and when driving in the field, forward driving is performed. When driving in reverse, the gear shifting position of the main transmission is set appropriately depending on the field conditions, and the set speed is changed by switching between two high and low gears using the auxiliary transmission. This is done by switching to the position.

In other words, when driving in the field, forward driving is performed by changing gears in a small gear ratio range using the auxiliary transmission, and backward driving is performed by switching the main transmission to reverse. When driving in the field, the machine turns around a lot and requires frequent switching between forward and backward movement, and having to do this by selecting two operating tools from separate driving control systems causes mental fatigue for the operator. This can lead to reduced work efficiency and erroneous operation.

In the present invention, forward and backward switching is performed frequently, and
The object of the present invention is to focus on the operation of traveling in a field where the gear change for forward traveling is performed in a small speed ratio range, and to configure this operation so that this operation can be performed with a single operating tool.

That is, the mobile agricultural machine according to the present invention includes a main transmission for switching the traveling speed to multiple forward speeds, and an auxiliary transmission for changing the traveling speed to two high and low speeds, and a control tool for the auxiliary transmission allows the machine to be controlled. It is characterized by being configured such that a lateral operation on the forward side in the direction of travel allows switching between two forward and low stages, and a pulling operation towards the rear in the direction of travel of the aircraft allows for reverse switching.

According to this configuration, the auxiliary transmission device performs a lateral operation on the forward side in the forward direction of the aircraft to perform a two-speed gear changeover operation, and a reverse shift operation by pulling the gear toward the rear in the forward direction of the aircraft. It can be operated by a tool, and therefore, by setting the gear shifting position of the main transmission in advance according to the field conditions, it is possible to perform forward and reverse shifting operations with a small gear ratio suitable for driving in the field. This can be done quickly and without mistakes by pushing and pulling a single operating tool back and forth in the direction of the aircraft's movement. Since only the forward gear change operation was performed on the front side, and the reverse gear shift operation was performed by pulling the gear towards the rear side, it became possible to frequently and reliably shift between forward and reverse gears with simple operations without much awareness.

As a result, it was possible to reduce the mental fatigue of workers while driving in the field, and to improve work efficiency.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

Figure 1 shows a combine harvester as an example of mobile agricultural machinery,
A side-blown top-handling type threshing section 1 is mounted on a crawler traveling device 2, and in front of the threshing section 1, a planted husk culm is raised and harvested, and the cut husk culm is supplied to the threshing section 1. A reaping pre-processing section 3 is provided, and a control section 4 is disposed on the side of this pre-processing section 3.

The operating section 4 has an operating section A having a main clutch operating tool 5 and left and right steering clutch operating tools 6, 6 disposed in front of the operating seat 7, a threshing clutch operating tool 8, a reaping latch operating tool 9, Main transmission operating tool 10, sub-transmission operating tool 11
An operating section B with a handle is arranged on one side of the pilot seat 7.

The operating tool 10 for the main transmission controls the switching operation of the traveling speed of the three forward gears including the neutral position and the neutral position, and the operating tool 11 for the auxiliary transmission controls the operation of the traveling speed of the three forward gears by the main transmission. In addition to switching the speed in two high and low stages, it also controls the switching of two high and low stages in reverse.

In other words, the sub-transmission device 11 is configured so that it can be switched to two stages of forward height and low by a lateral operation on the forward side in the direction of movement of the aircraft, and it is possible to switch to reverse by pulling the operation tool 11 toward the rear in the direction of movement of the aircraft. -ing

That is, the main transmission operating tool 10 operates three forward stages, and the sub-transmission operating tool 11 performs switching between two high and low stages of forward movement and reverse.
By the selection operation, a switching operation between six forward speeds and two reverse speeds is performed.

The operation guide groove 12 of the auxiliary transmission operating tool 11 is formed in a U-shape in a plan view that opens on the rear side in the direction of movement of the aircraft, and when the operating tool 11 is pulled in the front-rear direction, the aircraft moves backward, and then in the left-right direction of the aircraft. The configuration is such that switching between high and low levels can be performed by the operation of .

A neutral position may be formed in the guide groove 12 during this change in height during forward movement.
