Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for notifying a driver of the handling of grain culms in a combine harvester.

When harvesting with a combine harvester, if the position of the tip of the husk relative to the handling barrel during threshing is not appropriate, the entire tip of the culm may not be handled and the culm may be left unhandled), or the culm may break when handling the kernel. Therefore, in order to prevent this, the handling depth is adjusted by moving the culm toward the grain storage during transportation after harvesting to adjust the position of the tip relative to the handling barrel.

Conventionally used devices for this purpose include a swingable transport device that clamps and transports the base of the shell culm, which is swung by operation from the pilot's seat. However, the operator must sit in the driver's seat and operate the control lever while constantly monitoring the culm in the field and the grain being transported, making it difficult to respond immediately to changes in culm length. , operations were often delayed.

Conventionally, a sensor for detecting grain culm length was installed in the reaper, or a sensor was installed at the entrance of the threshing machine to detect the grain tip, and if the handling depth was not appropriate, a buzzer or lamp would notify the operator. A handling depth reporting device has been proposed and used.

However, with conventional devices, even if the device is installed, if the handling depth is not adjusted at the start of work, the display device will not operate until after the culm has passed the sensor position. Because the operation lever was operated, the husk of the cane was not adjusted and was fed to the threshing machine, resulting in the husks being treated too shallowly or unhandled, resulting in crosses that required re-threshing. there were.

The present invention has been made in view of the above-mentioned points.The present invention has been made in view of the above-mentioned points, and has an over-shallow handling depth detector and an over-shallow indicator connected directly to the main switch, and when the main switch is closed, the indicator indicates that the handling depth is too shallow. The structure should be configured to display the past and present, and the shallow treatment at the beginning of work is dependent on the structure! 1. To provide a handling depth informing device for a combine harvester which is designed to prevent the occurrence of leftovers. Embodiments of the present invention will be described in detail below with reference to the drawings.

At the front end of this reaper 18, a plurality of weeding bodies 20 are attached to each of the weeding pipes extending forward along the ground by scraping the culm 1s to be planted in the field to determine the cutting width as the machine moves forward. 21, supported by the imperial edict, behind it.

A pair of left and right lifting devices 22 for lifting up and conveying the tips of the fallen culms 19 to raise the stiffness are supported by lifting pipes 2s and are erected with a rearward inclination. What is generally designated by the reference numeral 24 is a culm conveying device, which includes a pair of tip conveying devices (front) 25 arranged in a V-shape.
and the tip conveyor (rear) that extends rearward from the confluence.
26, and each tip conveyor 25.2@ includes a tip chain in which a large number of lugs 27 are arranged at regular intervals;
It is composed of a tip guide 28 supported along the running trajectory of the tip of the lug 21. Furthermore, the 1-grain S conveying device 24 includes a pair of root conveying devices (front), not shown, which are arranged below the ear conveying device (front) 25 in parallel with each other in a V-shape, and behind the root conveying device The root conveying device (rear) 29 is disposed below the (rear) 26. Of these, the root conveying device (rear) 21B includes a root chain 30 stretched in a chain case that can freely swing around the starting end, and a root chain 1tIIIK supported by its running end KfB and biased by a spring member. As shown in FIG. 3, the tip guide 21 is formed in an upper and lower direction 2R and is fixed to a guide 32 of the clamping rod 1. The operating device 17 is provided with a handling depth adjustment lever 33, and by operating this from the cockpit 11, the entire base conveying device (rear) 2B can be swung in the vertical direction in FIG. It is configured to move the clamped culm 1!1 toward the grain.

The detection 1 indicator of the handling depth 11 section device is configured as follows. First, the tip conveying device (rear) 2
Above the tip guide plate 35 fixed to the tip of the chain case 34 of No. 6, there are a too-shallow detector 36 and an too-deep detector for detecting the position of the tip of the culm 1F that rests on the tip guide plate 35 and is conveyed. 81 are fixed to the machine stand side and arranged in parallel in the length direction of the tip. Further, in the lifting device on the right side in the direction of movement of the machine, there are an overly shallow indicator lamp 38 that indicates that the handling depth is too shallow, and an overly deep indicator lamp 39 that indicates that the handling depth is too deep. 40, and its arrangement is similar to that of the handling depth adjustment lever 33.
They are set in relation to each other so that the too-shallow indicator lamp 38 is located on the deep handling adjustment side. The display lamps sa and ss are arranged on a line connecting the pilot's seat 11 and the tip of the branching body sO on the right side in the direction of travel. The space is configured so that it is within the line of sight when viewing the state. FIG. 4 is an electric and sign diagram of these detectors 36, 37 and indicator lamps 38, 19, and on the wiring connecting the power source 41 and the operating switch 42, there is a detector s @ for too shallow, Indicator lamp 38 and too deep detector 1? , and the display lamp 3s are directly connected in parallel, and the too-shallow detector 3@ indicates that the culm 11 is not present or the grain culm length is short.
(closed when not touching), and too deep detector 3
In case of No. 1, the shell culm 19 was not present (the length of the shell culm was short) and the tip of the spike was not in contact with it. When the activation switch 42 is turned on in the non-contact state, the too-shallow indicator lamp 3 on the closed side of the wire lights up, and furthermore, when the tip of the culm 19 comes into contact with the too-shallow detector 1@ in this state, Too shallow indicator lamp s8 turns off. Also,
When the tip of the culm 19 contacts the too deep detector 37, the too deep detector 37 closes and the too deep indicator lamp S- lights up. Furthermore, the power supply 41 and the wiring for the too-shallow indicator lamp 88 are connected by wiring equipped with a changeover switch 48 that switches the direction of movement of the machine between forward and reverse. Buzzer 44 that sounds when switching to
is connected. 45Fi is an OK monitor that warns of abnormalities in the engine, threshing unit, etc., and is mounted on the top surface of the operating device 14, located on the line connecting the cockpit 11 and the weeding body 20.

0 to explain the operation of the combine configured as above.
As the machine moves forward, the culm 1 to be planted in the field becomes the culm 2.
0, and after being pulled up by a pulling device 22, the root portion is cut off with a cutting blade (not shown). The harvested culm is transferred to the tip conveyor (front) 25 and the root conveyor (front).
The ears are captured and conveyed by the tip conveyor (rear).
26 and the root conveying device (rear) 29, and the threshing machine 4
After being transported to the farm, the grain is threshed.

In such a reaping operation, when the operator 10 is seated in the operator's seat 11 and turns on the operation switch 42 to start the operation, both the culm 1g is transferred to the frame photographing and transmitting device (rear) 2@, 29. Detector $11.3? culm 1 is detected in the detection part by
Since s does not exist, the too-shallow indicator lamp 38 lights up at the same time as the activation switch 42 is turned on. At this time, the operator 10 checks the condition of the culm 1 by the cutting body 20.
By steering the platform, the operator 10 can confirm that the too-shallow indicator lamp s8 within his line of sight is lit, and after confirming this, the operator 10 turns the handling depth adjustment lever 33 to the deep handling depth side. make it move. This causes the root conveying device (rear) 2s to move to the third position.
Since it moves upward in the figure, the culm 1s that has reached the detection part is conveyed while its tip is in contact with the too-shallow detector 3@, and the too-shallow indicator lamp s8 goes out. In this way, at the start of work, the too shallow indicator lamp ss is always lit,
The operator 1◎ confirms this and adjusts to the deep handling direction, so when the culm reaches the threshing machine 4, it will not become shallow handling, and the arrangement position of the too-shallow indicator lamp 38 will be adjusted to the deep handling direction. Since it is set to the same direction as the depth adjustment direction of the adjustment lever 33, there is no possibility of making a mistake in the adjustment operation.

After this, if the reaping work continues and the culm length of the culm tS becomes longer, when this culm 1@ reaches the detection part, the tip part contacts the too deep detector 37 and this closes. , the too deep indicator lamp 39 lights up. The operator 10 confirms this within his/her line of sight and turns the depth adjustment lever 33 until the excessive depth indicator lamp 39 goes out, and the root conveying device (rear) 2!1 moves to move the culm 1B. Since it is moved in the direction of the stock, the tip part is separated from the deep handling detector 31 and becomes shallow handling. In addition, when the shell culm 19 is a short culm, the tip of the culm moves away from the too-shallow detector 3ii, and the operator 10 can confirm that the too-shallow indicator lamp 38 is lit within his/her line of sight. By operating the handling depth adjustment lever 33 in the deep handling direction, the root conveying device (rear) 2B moves and the culm 19 moves toward the tip, making it possible to achieve an appropriate handling depth. Wow. When the changeover switch 44 is operated to move the machine backward, the buzzer 45 sounds and the too-shallow indicator lamp 38, which is shared by the machine, lights up. Although an example is shown in which an indicator lamp is used as an indicator of too deep, a buzzer may be used for both, or a buzzer may be used for either one.

As is clear from the above explanation, according to the present invention, in a combine harvester, a too-shallow grain handling depth detector and an too-shallow indicator are directly connected to the main switch, and when the switch is closed, the grain handling depth is detected by the indicator. It should be configured to display the indication that the depth is too shallow, and at the start of work, the operator should adjust the handling depth in the direction of deeper handling before the culm handling depth adjustment operation is started. Since the adjustment lever is operated reliably when prompted to do so, regardless of the length of the grain culm, it will not be handled too lightly, and there will be no unhandled grain, resulting in less grain loss.
can be reduced.
