Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for an armrest in a driving section of a mobile agricultural machine.

In other words, in the operating section of a mobile agricultural machine, which consists of a control column in front of the step on which the driver rides, and a seat erected behind it, the driver not only operates while sitting on the seat, but also stands on the step. In such cases, conventional models change the posture of the seat seat or backrest so that it serves as a lumbar rest when standing. As has been said before, in order to change the posture of this seat or backrest, the driver must turn backwards and perform the posture change operation, which has the disadvantage of neglecting the view ahead while driving. .

Therefore, the present invention provides a device that can easily change the posture while driving while looking forward without turning backward, and can be suitably implemented with a simple structure.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of the combine harvester, in which a reaping section 8 is installed at the front of the machine body supported by crawlers 7, a threshing section is installed at the rear thereof, and a step is installed at the front right side of the machine body. A control column 2 and a side column 11 equipped with operating levers 9, 10, etc., respectively, are installed on the upper front and left side of the step 1, and a seat column 12 is provided upright at the rear of the step 1 behind the control column 2. A seat 3 with an integrated seat and backrest is installed above, and a paddy tank 15 equipped with a large number of paddy outlets 14 at the bottom is installed above a paddy holder 13 installed at the rear lower part. However, an engine section 16 is installed behind it, and the structure is similar to that of the conventional structure.

A vertical cylindrical support 4 is fixed to the upper side of the seat column 12 on the front side of the seat 3 on the outside of the fuselage via support pieces 17 and 18, and the upper end surface of the support 4 is has both notches 19, 19 which are straight in the front and back direction, and both notches 19, 19.
Both notches 20, 20 are formed in a straight line in the lateral direction at 90 degrees with respect to the direction.

Further, the lower part of the vertical part 5b of the support rod 5 is fitted into the support rod 4, and the support rod 5 is rotatably erected.
Alternatively, a support pin 21 that can be engaged with 20, 20 is inserted, and a horizontal portion 5a extending horizontally in a direction orthogonal to the support pin 21 is integrated into the upper part of the support rod 5 and bent into a square shape. , the horizontal support 6 is aligned above the horizontal portion 5a.
The support body 6 is formed so as to function as an arm rest and a waist rest.

Therefore, the vertical portion 5b of the support rod 5a is connected to the support metal 4.
At the same time, the support pin 21 is inserted into the notch 2.
0 and 20 and are locked, the support body 6 is attached to the upper part of the outer side of the fuselage body of the seat 3 in the longitudinal direction, as shown in FIGS. 1 to 6. This serves as an armrest for driver A sitting on seat 3.

Further, when the support rod 5 is fitted to the support metal 4 so that the support pins 21 are fitted and locked in the notches 19, 19, the support body 6 becomes a sheet as shown in FIGS. 7 to 10. It is installed horizontally above the front part A of Step 3, and serves as a lumbar rest for driver A who stands on Step 1 as shown in Fig. 10.

In this way, the support body 6 can be used by switching between an armrest and a waist rest. However, when performing the switching operation, the driver can lift the support rod 5 with his right hand without having to turn backwards and insert the support pin 21 into the notch. If it is pulled out and rotated 90 degrees, the support pin 21 will fit into the other notch, making it easy to operate.

As described above, the present invention provides a driving section of a mobile agricultural machine which is constructed by disposing a control column in front of a step and a seat behind the step, in which the seat is fixedly mounted on the front side of the seat and on the outside of the machine body. The vertical part of the support rod, which is formed in a square shape, is fitted into the support metal to be rotatably erected. Since the support attached to the seat is configured to double as an armrest and lumbar rest, when the driver sits on the seat and drives, the support can be placed on the outside of the seat and oriented in the front-rear direction. It can be used as an armrest, and when the driver stands on the step while driving, the support can be oriented horizontally above the front of the seat to support the driver's hips and drive safely. Moreover, since the driver can use the support rods on the side to change the posture of the support, it is possible to do so without turning backwards, making it easy to change the posture while driving while looking ahead. It has the advantage of being able to be carried out suitably with a simple structure.
