Another Embodiment Next, another embodiment will be described with reference to FIGS. Another embodiment is a configuration in which the noise generated due to the transport and raising of the grain stalk is prevented by using the ventilation type sound insulation panel 40 based on a special structure. First, as shown in FIG. 11, the ventilated sound insulation panel 40 is provided with a communication hole 42 and a semi-communication hole 43 having an intermediate opening between two plates 41 and 41 'spaced apart from each other. It is composed. When the sound wave passes through the two communication holes 42 and 43, the sound wave that enters from one side has a phase opposite to each other in an arbitrary frequency region when the sound wave passes through the two communication holes 42 and 43. The sound is reduced by the effect. That is, sound waves (noise) passing through the ventilation type sound insulation panel 40
Is in the state of the graph shown in FIG. 12, the sound is greatly reduced compared to before the passage, and the state shown by the thick line in the graph is obtained.

Note that the mowing transport dust cover 47 includes a front dust cover 47a fixed to the machine body and a rear dust cover 47b slidable back and forth. The ventilation type sound insulation panel 40 of the embodiment is mounted inside the front dust cover 47a as shown in the figure.

The ventilation type sound insulation panel 40 of the following embodiment is
As shown in FIG. 9 and FIG.
Provided inside the front cover 48 to prevent noise
I have. Next, the operation will be described. First, engine
Start the harvesting clutch device and threshing clutch device.
Entering operation to transmit the rotating parts of the aircraft,
When the controller 2 is operated to move forward, the controller 6
Latch sensor S₇, Threshing clutch sensor S₈, Vehicle speed sensor
S ₉The work start signal is input from
Control operation is started.

When the combine starts harvesting and threshing in this way, the culm in the field is replaced with the weeding rod 1 at the lower front end.
7 and then the culm raising device 18
Is raised from the lying state to the upright state by the raising action, the root of the stock reaches the reaping device 16 and is cut off, and is squeezed by the action of the scraping ring 19a and the scraping endless band 19b to be raked. 20 and are conveyed sequentially upward in a continuous state.

A large number of rows of the culm are collected, conveyed by the left and right front conveying devices 20 and merged at the rear, and successively transferred from the handling depth adjusting device 4 to the supply adjusting device 5 in a continuous state. The feed reaches the starting end of the feed chain 10 and is supplied to the threshing apparatus 1. The grain culm is threshed by the rotating handling cylinder while the spike portion is inserted into the handling chamber 11 and passed while the stock is conveyed with the stock clamped by the feed chain 10. Then, the threshing product reaches the lower sorting room and is subjected to the sorting wind and the action of the rocking sorting device to be sorted.

As described above, the combine continuously performs harvesting and threshing work, harvests the selected threshed grains, and collects and stores them in the Glen tank. Now, as described above, when the cutting and threshing operation is continuously performed, the pre-cutting device 3
Is held at the height of the normal working position of the lower, that position from the position sensor S ₁ control - are input to the La 6. Then, each of the transport culms are input detected from culms sensor S ₂ and strains based on the sensor S _3. Also,
Culm sensor S ₄ is entered by detecting the grain稈丈.

[0030] Then, threshing depth adjustment device 4, the detection information from the strain based sensors S ₃ and the tip sensor aS ₅ and the tip sensor bS ₆ is control - are input to the La 6, control based on it - La 6 the outputted threshing depth controlled by the operation signal mode - motor -M ₁ is controlled actuated, automatically threshing depth through the communicating rod 21 is adjusted. In this case, controller - La 6, the position where the strain based sensors S ₃ maintaining the control state if the grain稈検out state, passes between the tip position of the transport culms of the tip sensor aS ₅ and the tip sensor bS ₆ Is determined to be the position of the most appropriate handling depth, and the adjustment is controlled so that the adjustment position of the handling depth adjustment device 4 is adjusted to that position.

[0031] At this time, controller - La 6, as described above, there are strains based sensor S ₃ in cereal稈検out state, of course, because a state out even grain稈検culms sensor S _2, ridge when the control (feed Control of the adjustment device) has also been established. Next, the traveling body 2
When the reaping of the headland is reached at the edge of the field,
In order not to collide the tip of with the ridge rising at the end of the field, the cutting and lifting cylinder -38 is extended, and the cutting pre-processing device 3 is moved up to the high cutting work of the grain culm while ascending.

The ridge control will be described below. First, in a state where the reaping clutch sensor S ₇ , the threshing clutch sensor S ₈ and the vehicle speed sensor S ₉ are ON (during operation),
The mowing pre-processing device 3 is raised to the high mowing position, and the operation shifts to cutting the headland. At this time, controller - La 6, since the control state as described above, the position sensor S _1, the detection information of the culms were fed the height position of the preprocessing device 3 reaper from culms sensor S ₂ Has been entered.

The controller 6 includes a culm length sensor S
₄ detects the cereal stem that has been sent and inputs the detection information, determines that the cereal stem length is longer than the reference value (60 cm), controls only the handling depth adjustment device 4, and inputs the non-detection information. It is determined that the grain culm length is shorter than the reference value (60 cm), and the control by both the handling depth adjusting device 4 and the supply adjusting device 5 is performed simultaneously.

First, the controller 6 includes a culm length sensor S ₄
When the detection information is input from, in the embodiment, the output 1, 5 / sec threshing depth control mode -扱深controls the motor -M ₁ the depth Threshing side adjustment device 4 to about 15cm Fuka扱Do the work by adjusting to the cut side. Complete cutting high by the control operation described above, strains based sensor S ₃ is completed by detecting that there are no more culms. Thereafter, the handling depth adjusting device 4 is turned off-delay.
Returns to the shallow side by about 12 cm with a predetermined time delay, and returns.

On the other hand, the grain culm length is extremely short,
Sensor S_FourUndetected information is sent to the controller 6 without reaching
Is input to the controller 6, the controller 6
A signal for adjusting the supply adjusting device 5 to the deepest handling position is output.
Each handling depth control motor M ₁And supply control motor M_TwoTo
Output and control. Therefore, it is provided with the
The feed adjustment device 5 is controlled to the position of the deepest handling and extremely
The short culm is supplied to the threshing apparatus 1.

In this case, the supply control device 5 is controlled and controlled.
Inherits a very short cereal stem that is largely adjusted to the deep-hand side from the end of the handling-depth adjusting device 4, and is further adjusted to the deep-hand side to supply to the auxiliary feed chain 12. However, at this time, short grain culms whose roots do not reach the clamping position of the feed chain 10 are conveyed by the auxiliary feed chain 12, and all the culms are directly introduced into the handling room 11 from the supply side.

[0037] When one step of to cutting threshing operations as described above is completed, controller - La 6 determines the end by detecting that the strains based on the sensor S ₃ is no longer culms,
With a certain time delay, the handling depth adjusting device 4 and the supply adjusting device 5 are returned to the shallow handling position.
