Description

  The present invention relates to a combiner control unit structure.

In order to perform harvesting work at night, the combine needs to brightly illuminate the front of the aircraft and bright enough to confirm the harvesting status of the harvesting device in the harvesting device at the front of the aircraft.
For this reason, for example, as described in Patent Document 1, there is a configuration in which two headlamps are provided on the front panel standing on the front side of the cockpit provided on the left and right sides of the reaping device.

JP 2007-74 A

  There is a steering lever on the upper side of the front panel of the combine, but this steering lever is tilted to the left and right to operate the hydraulic valve that operates the side clutch of the crawler traveling device to change the traveling direction, The hydraulic valve of the cutting lift cylinder that lifts and lowers the cutting device by tilting is operated.

  For this purpose, as described in Japanese Patent Application Laid-Open No. 2007-74, when two large headlamps are provided on the front panel, a hydraulic valve is installed at a position away from the steering lever and steered with a wire or the like. The lever and the hydraulic valve must be connected, and the operation of the steering lever is not directly connected to the switching of the hydraulic valve, and the steering feeling is not good.

  Therefore, in the present invention, the headlamp is placed on the front panel while the hydraulic valve is installed near the steering lever and the movement of the steering lever is transmitted to the switching operation of the hydraulic valve with less play to improve the steering feeling. It makes it a subject to make it the structure to attach.

The problems of the present invention are solved by the following technical means.
That is, a steering lever (1) is erected on the upper surface of the front panel (2) standing on the front side of the cockpit (F), and the left and right side clutches are operated by tilting the steering lever (1) left and right. The hydraulic valve (3) to be operated is provided in the front panel (2) below the mounting portion of the steering lever (1), and a front panel (2) below the hydraulic valve (3) is provided in front. It is set as the control part structure of the combine characterized by arrange | positioning the headlight (4).

  Since the hydraulic valve (3) is provided immediately below the steering lever (1) and the left / right tilting of the steering lever (1) is directly used as the switching operation of the hydraulic valve (3), the steering lever (1) is operated. The front panel (2) is equipped with a headlight (4) and the front panel (2) is brightly illuminated at night by brightly illuminating the front of the fuselage and the reaping device. Can be harvested safely.

It is a side view of a combine. It is a front view of the front panel of a combine. It is a partially broken front view of the front panel of a combine. It is a sectional side view of the front panel of a combine. It is a top view of a transmission lever. It is a perspective view of the front panel of the combine of another Example. It is a top view of a cockpit.

Embodiments of the present invention will be described below with reference to examples shown in the drawings.
The front of the fuselage is the forward direction of the combine, and the left and right are the left and right in the forward direction.

  As shown in FIG. 1, the combine body has a threshing device (not shown) and a grain storage device D arranged side by side on the upper side of a chassis B provided with a crawler type traveling device A, and a grain storage device D An engine cover E surrounding the engine is provided on the front side of the engine, and a seat (control seat) F is provided above the engine cover E, and a front panel 2 is erected in front of the seat F. The front panel 2 and the threshing device The reaping device G is provided on the front side so as to be movable up and down.

  The drawing shown in FIG. 2 is a front panel 2 of a control unit provided on the right side of the front side of the combine body. A steering lever 1 is erected on the operation display panel 6 on the upper surface of the front panel 2. A handle bar 8 is provided so as to cover the upper side.

  The front panel 2 is a plate-like body that covers the front side, and the steering lever 1 is attached to the inner panel frame 18, and the hydraulic valve 3 is switched by the steering lever 1 at the lower side. A light cover 10 that bulges forward from the front panel 2 is attached to the front panel 2 from the front side to the lower side of the hydraulic valve 3, and a small day marker light 5 is provided on the upper side inside the light cover 10. The headlamp 4 is provided. Since the light cover 10 bulges forward, a day marker light 5 is provided in front of the hydraulic valve 3, and the headlamp 4 can be enlarged. The day marker light 5 is turned on for safety when traveling on the road during the day.

In addition, although the front side part of the headlamp 4 of the light cover 10 is made transparent, the front side part of the day marker light 5 is made blue or changed in shape.
The day marker light 5 is lit when the shift lever 11 shown in FIG. 5 is moved from the neutral position N to the travel position A or back position C to inform the workers around the aircraft that it is traveling. Can be safe. When the shift lever 11 is set to the parking position B, a brake is applied to the traveling device, and when the transmission lever 11 is set to the back position C, a buzzer sounds while traveling backward.

A side mirror 7 for viewing the rear of the fuselage is provided on the upper side of the front panel 2, and a front mirror 9 for viewing the cutting device on the front left side of the fuselage is provided on the upper part.
In the embodiment shown in FIG. 6, a key box 15 is provided on the right side of the upper end of the front panel 2, and a parasol support rod 12 projects from the key box 15 forward. A parasol insertion ring 13 for inserting a parasol handle is fixed to the tip of the parasol support rod 12, and a cup holder 14 is fixed to an intermediate portion of the parasol support rod 12.

  A reinforcement rod 16 that reinforces the attachment of the key box 15 and the parasol support rod 12 approaches the front of the operation display panel 6 and is connected to the clutch support frame 17 on the left side of the front panel 2. The clutch support frame 17 connects and reinforces the panel frame 18 with the rear part of the machine body.

In addition, you may attach the auxiliary | assistant work lamp which illuminates the front of a body to the reinforcement rod 16. FIG.
FIG. 7 is a plan view of the cockpit 20, in which a normal horn switch 18 is provided in the key box 15 at the front right side, and an emergency horn switch 19 is provided in the side panel 21 at the left side. The normal horn sounded by the normal horn switch 18 and the emergency horn sounded by the emergency horn switch 19 are provided separately on the left and right of the front panel 2, and the emergency horn has a higher volume.

  When the emergency horn switch 19 is pressed, the emergency horn sounds. When the emergency horn switch 19 is pressed while being sounded, the ringing is stopped. Further, when the emergency horn switch 19 is pressed when the storage setting of the storage memory is changed, the memory is rewritten.

  The normal horn switch 18 is used during normal field work, and the emergency horn switch 19 is used during road driving. In particular, when an abnormality occurs in the combine to notify a distant worker, the emergency horn switch 19 is used. 19 is used. In addition, since the normal horn and the emergency horn are provided separately, there is no problem in work or on the road even if one of them breaks down.

  In the configuration in which the combine body can be rolled with respect to the traveling device, a short coupler is provided instead of the switch, this short coupler is inserted, the work mode is removed, the short coupler is removed, and the sensor check mode is entered. It is possible to change the storage setting of the storage memory in the sensor check mode, and to change the storage setting of the horizontal sensor and the left and right positions by switching the horizontal automatic switch on and off.
