Abstract

PROBLEM TO BE SOLVED: To prevent the excessive deposition of grains on an oscillating rack, sheap clogging and the damage to oscillating rack caused by overload and to improve ability of sorting grains. SOLUTION: When a flow rate sensor 48 senses a flow rate higher than a specified value and an on-rack volume sensor 49 shows the volume less than a specified value, it is shown that the flow rate of grains through a 2nd processing chamber terminal part is higher than the specified value, since the increase in deposited grain height on an oscillating rack after the lapse of short time can be predicted although the deposited grain height on the oscillating rack 21 is low at present, while facilitating the passage of grains by opening a sheap for two stages, for example, and while improving the grain sorting ability by increasing the blown air volume of sieve by opening a Chinese sieve shutter for one stage, for example, control is performed for preventing the deposited grain height on the oscillating rack 21 from getting excessive at the next time point.

While moving in the direction of arrow D of 7, the wind of Karino 39 a rotating in the Karamin casing 39 is received and the wind is sorted out.
As for the grains having a high specific gravity, the sieve 22 and the sorting net 23 are shown in FIG.
, Is accumulated on the first shelf 24, and is transported to the first fryer cylinder (not shown) by the first spiral 25.

The remaining grains and straw chips on the swinging shelf 21 are blown off by the sorting wind of the rocking operation and Karamin 39a, and move on the sheave 22 in the direction of arrow D in FIG. The remaining grain and straw having a light specific gravity fall in the direction of arrow G and are collected on the second shelf 58, and are conveyed to the second fried grain cylinder 60 by the second spiral 59. Large straw chips and the like are put on the straw rack 16 and are discharged from the combine 1 to the field as shown by the arrow F for the swing operation of the swing shelf 21.

[0004] The material to be treated on the second shelf plate 58 is a mixture of normal grains, branch stalks, straw chips, and sari grains having normal grains stabbed in the straw chips (second grains). ), And as shown in FIG. 16 and FIG.
And discharged from the second processing chamber 27 through the second discharge port 60b. The second processing cylinder 30 at the lower part of the second processing chamber 27 is rotated in the direction of arrow J in FIG. 16 by a driving device (not shown), and the second kernels are processed by a number of processing teeth planted in the second processing cylinder 30. The second grain is separated while traveling in the direction of arrow I (FIG. 17) while colliding with 30a, and a part of the separated grain and straw waste pass from the second processing body receiving net 35 in the direction of arrow C2. The remaining grains and straw chips separated from the rack 21 are then flipped up and rolled up by the rotating blades 30 b planted at the transport end of the second processing cylinder 30, and are rolled up. 27 is guided in the direction of arrow C3 from the end portion 27a and falls onto the swinging shelf 21.

In the direction, and is received by the swinging shelf 21. On the other hand, the processing teeth 30 of the second processing cylinder 30 rotating in the second processing chamber 27.
The grains and straw chips that have collided and separated in a.
5 in the direction of arrow C2, and the end 2 of the second processing chamber 27.
It is guided in the direction of arrow C3 from 7a and falls on the swinging shelf 21. The pile height of the grains and the debris that have fallen and fallen on the swinging shelf 21 depends on the mounting frame of the handling net 34 and the shelf attached to the lower surface of the frame between the second processing body receiving net 35 and the handling net 34. It is detected by the upper volume sensors 49, 49 and transmits a control signal described later.

The swing shelf 21 has a slight inclination in the left-right direction shown in FIG. 16 and is inclined in the longitudinal direction shown in FIG. 17, and swings by the swing of the swing shelf 21 in the vertical and longitudinal directions. While conveying the grains and the like deposited on the upper surface of the shelf 21 in the direction of arrow D, the grains and the straw chips are sorted and separated by the sorting wind from Karamin 39a. For this reason, while swinging together with the swinging shelf 21, the grains and small straw chips pass through and are separated from the swinging shelf 21, and the sorting wind from the Karamin 39 a is guided to float, diffuse and transport the object to be processed. A sheave 22 is provided.

A conventional sheave 2 will be described with reference to FIG.
2 and the operation of the control of the shutter of Karamin 39a will be described. First, in step s1, the opening of the sheave 22 is set.
Here, as an example, it is assumed that the sheave 22 has five degrees of opening, and the third degree is set in the middle of the five degrees. Next, in step s2, the opening degree of a shutter (not shown) for opening and closing the opening provided in the casing 39 of the Karamin 39a is set. Here, as an example, it is assumed that there are five stages of shutter opening, and the second stage is set. In step s3, manual operation or automatic operation is selected. If it is manual operation, the process proceeds to step s4,
The operation is continued at the third stage of the sheave 22 and the second stage of the Karino shutter opening, which were previously set. If necessary, the opening of the sheave 22 and the opening of the Karino shutter are changed by changing the sheave opening setting dial and the Karamino shutter opening setting dial, and the manual operation is continued.

If automatic is selected in step s3, the process proceeds to step s5, in which the falling height of the grains and straw chips that have fallen on the rocking shelf 21 is determined by the mounting frame of the handling net 34 and the second processing cylinder. It is detected by the on-shelf volume sensors 49, 49 attached to the frame between the receiving net 35 and the handling net 34, and it is determined whether the detected value is higher than a specified value. Is opened and closed to the dial set value (here, the third stage), and then step s7
The program proceeds to step s9, and after opening and closing the Karino shutter opening to the dial set value (here, the second stage), the procedure proceeds to step s8, where the operation of the threshing device 15 is checked.
After waiting for a predetermined time with the timer, the flow returns to step s5. If the operation of the threshing device 15 is NO in step s8, the process proceeds to step s12, and the operation of the threshing device 15 is stopped.

Accordingly, a threshing device 15 with a variable opening / closing opening of the sheave 22 and a variable opening of the shutter for adjusting the air flow rate of the Karamin 39a.
In FIG. 25, if the automatic operation is performed according to the control flow shown in FIG. 25, the pile height of the kernels and straw chips dropped and accumulated on the swinging shelf 21 is detected by the on-shelf volume sensors 49, 49,
If the accumulation height of the grains and the straw debris that have fallen and accumulated on the swinging shelf 21 is high, the sheave 22 and the shutter of the Karamin 39a are opened by one step, and the grains on the swinging shelf 21 are opened. 22 and Kara 39a suitable for the operating condition of the threshing equipment, such as automatically operating to eliminate the accumulation of ash
The operation of the opening and closing of the shutter is automatically controlled to an appropriate value, so that the performance of the threshing device 15 is improved, and the operation of the threshing device 15 and thus the operation of the combine 1 can be made extremely easy.

[0010]

According to the flow of the prior art automatic operation control of the threshing apparatus 15 shown in FIG. 25, the piled-up height of the grains and straw chips that fall on the rocking shelf 21 and accumulate. When the height becomes high, the on-shelf volume sensors 49, 49 detect and automatically open the sheave 22 and the shutter opening of Karamin 39a so as to eliminate the accumulation of grains and the like on the swinging shelf 21. Driving can be performed.

However, after the accumulation height of the grains and the like accumulated on the swinging shelf 21 increases, this is detected by the on-shelf volume sensors 49, 49, and the opening of the sheave 22 and the opening of the shutter of the Karamin 39a are detected. In the control method for opening the degree, the sheave 22
Due to the time delay until the opening of the sheave 22 and the opening of the shutter of Karamin 39a are opened, and the time delay until the effect of opening the opening of the sheave 22 and the opening of the shutter of Karamin 39a appear. The accumulation of the object 21 does not disappear, and the accumulation of the object to be processed continues, and the accumulation height of the swinging shelf 21 may become excessive. If the accumulation height of the swinging shelf 21 becomes excessive, the sheave 22 is clogged. Is generated, and an excessive load is applied due to excessive accumulation of the objects to be processed (threshed, such as grains and straw chips) on the swing shelf 21, and the swing shelf 2 due to the excessive load is applied.
In order to avoid such damages, it is necessary to set the opening of the sheave 22 and the shutter opening of the Karamin 39a to be large beforehand. In any case, the grain recovery rate is reduced due to the accompanying grain accompanying the excessive size.
There is a problem that the performance of the device is deteriorated.

[0012] Therefore, an object of the present invention is to prevent damage to the rocking shelf caused by excessive accumulation of the material to be processed on the rocking shelf, clogging of the sheave, and overload, and to prevent the rocking of the rocking shelf (such as grain and straw chips). ) To improve the performance of the threshing apparatus and to exhibit an extremely excellent effect.

[0013]

The above object of the present invention is attained by the following constitution. That is, the handling cylinder part for threshing the grain stem, the second processing barrel part for threshing the second kernel, and the object to be treated that is threshed and dropped by the handling cylinder part and the second processing barrel part, and The second treatment in a threshing device equipped with a rocking shelf equipped with a sheave with adjustable opening and closing, and a Karamin with an adjustable air flow for separating the grains and straw in the object to be processed on the rocking shelf by wind. No. 2 reductant amount detecting means for detecting the amount of the second reductant contained in the to-be-processed object at the end of the to-be-transferred object in the conveying direction, and for detecting the amount of the to-be-processed object deposited on the swinging shelf A material amount detecting means is provided, and the amount of the object to be processed on the rocking shelf is adjusted to an appropriate amount by comparing the detection value of the second reduced material amount detecting means with the detection value of the object to be processed amount detecting means and each set value. A threshing device equipped with a control device for controlling the sheave opening and closing degree and .

[0014]

Embodiments of the present invention will be described.
The combine to which the present invention is applied has the configuration shown in FIGS. 1 to 23. The flow of the operation control of the threshing device 15 is shown in FIGS. 3 to 11, which is an improvement on the prior art shown in FIG. is there.

That is, in the present invention, for example, the following control is performed. When the flow rate sensor (second reductant flow rate detecting means of the present invention) 48 shown in FIG. 2 which detects the amount of grain contained in the processing object detects that it is equal to or more than a specified value, the on-shelf volume sensor ( When the amount of material to be processed (layer thickness) detecting means 49 of the present invention is less than the specified value, the flow rate of the material to be processed (second reduced material) passing through the second processing chamber end portion 27a is not less than the specified value. Therefore, even if the height of the object to be processed on the swinging shelf 21 is currently low, it can be predicted that the height of the object to be processed on the swinging shelf 21 will increase after a short period of time. For example, opening the opening 22 in two steps to facilitate passage of the object to be processed and opening the Karino shutter one step, for example, to increase the blowing air volume of the Karino 39a to increase the sorting ability of the object. In addition, after a predetermined time, the height of the object to be processed on the swinging shelf 21 is increased. Performs control to advance prevents becomes excessive.

When the on-shelf volume sensor 49 is equal to or higher than the specified value and the flow rate sensor 48 is lower than the specified value, the flow rate of the processing object passing through the second processing chamber end portion 27a is lower than the specified value. Therefore, it can be predicted that the height of the object to be processed on the swinging shelf 21 will decrease after a short time even if the height of the object to be processed currently on the swinging shelf 21 is high. By reducing the opening, the passage of the object to be processed is made gentler, and the opening of the Karino shutter is greatly opened to reduce the opening of the sheave 22.
In order to prevent a decrease in the amount of air blown at 9a and to maintain the processing object sorting ability, the processing object stacking height on the swinging shelf 21 becomes too small at the next point in time, and the processing object sorting ability decreases. Is to be controlled in advance to prevent this.

In this way, it is possible to prevent the workpiece 21 on the swinging shelf 21 from being excessively deposited, clogging of the sheave, and damage to the swinging shelf 21 due to an overload, and to improve the sorting ability of the workpiece.
An extremely excellent effect for improving the performance of the threshing device 15 can be exhibited.

Here, as an example, it is assumed that the sheave 22 has five degrees of opening, and the third degree is set in the middle of the five degrees. Then, in step s2, the shutters 39i, 39j, 39k of the Karamin 39a,
An opening of 391 is set. Here, as an example, it is assumed that there are five stages of shutter opening, and the second stage is set.

At step s3, manual operation or automatic operation is selected. If it is manual operation, the operation proceeds to step s4, and the operation is performed at the third stage of the sheave 22 and the second stage of the Karino shutter opening which have been previously set. To be continued. If necessary, the sheave 22 and the Karino shutter opening are changed by changing the sheave opening setting dial and the Karano shutter opening setting dial to continue the manual operation.

If automatic is selected in step s3, the process proceeds to step s105, in which the flow rate sensor 48 detects the flow rate of the grain passing through the terminal end 27a of the second processing chamber 27, and the detected value is higher than the specified value. If NO is determined, the process proceeds to step s106, and the pile height of the grains and straw that have fallen and accumulated on the swinging shelf 21 is detected by the handling net 34 and the on-shelf volume sensors 49, 49, It is determined whether the detected value is higher than a specified value.
The process proceeds to step S7, and the opening of the sheave 22 is opened and closed at the dial setting value (here, the third stage). Next, the process proceeds to step s108, after opening and closing the Karino shutter opening to the dial set value (here, the second stage), proceeds to step s109, checks the operation of the threshing device 15, and if YES, proceeds to step s1.
Step s10: Waiting for the elapse of a certain period of time by the timer 10
Return to 5. In step s109, the operation of the threshing device 15 is N
If O, the operation proceeds to step s111, and the operation of the threshing device 15 is stopped. In step s105, the flow rate sensor 48 may detect the amount of the entire second reductant, not the grain but the straw waste.

In step s105, in the case of YES, the process proceeds to step s114, where the pile height of the grains and the straw debris deposited on the swinging shelf 21 is measured by the on-shelf volume sensors 49,4.
9 to determine whether the detected value is higher than the specified value.
Is opened by two steps (here, the fifth step), then the process proceeds to step s116, and the Karino shutter opening is opened by one step (here, the third step), and thereafter, step s1
Go to 09.

In step s114, if the detected value of the height of the grains and the debris deposited on the rocking shelf 21 is higher than the specified value, the flow advances to step s117 to open the sheave 22 to the maximum degree (here, (The fifth stage is reached.) Then, the process proceeds to step s118, and the Karino shutter opening is opened to the maximum (here, the fifth stage is reached).

When it is determined in step s105 that the detected value of the flow rate of the kernel passing through the second processing chamber terminal portion 27a is not higher than the specified value, the process proceeds to step s106 and the kernel is deposited on the swinging shelf 21. If the accumulation height of the grains and the straw chips is higher than the specified value, the process proceeds to step s112 to close the opening of the sheave 22 to the minimum (here, the first stage), and then proceeds to step s113 to increase the Karino shutter opening to the maximum. (Here is the fifth stage).

As described above, in this embodiment, when the flow rate sensor 48 detects that the value is equal to or more than the specified value and the on-shelf volume sensor 49 is smaller than the specified value (step s1).
15, step s116) includes the second processing chamber end portion 27.
a indicates that the flow rate of the processing object passing through a is equal to or greater than the specified value. Since it can be predicted that the height of the object to be processed increases, the sheave 22 is opened in two stages to facilitate the passage of the object to be processed, and
The opening of the Karino shutter is opened by one step to increase the air flow rate of Karamin 39a to increase the grain sorting capability, and that the pile height of the processing object on the swinging shelf 21 becomes excessive at the next time. Is performed in advance to prevent.

When the on-shelf volume sensor 49 is equal to or higher than the specified value and the flow rate sensor 48 is lower than the specified value (steps s112 and s113), the processing object passing through the second processing chamber end portion 27a is removed. Since the flow rate is less than the specified value, even if the height of the object to be processed on the swinging shelf 21 is currently high, if the height of the object to be processed on the swinging shelf 21 decreases after a short time has elapsed. As it can be predicted, the opening of the sheave 22 is closed to a minimum, the Karin breeze is weakened, the opening of the Karamin shutter is opened to the maximum, and the airflow of the Karamin 39a due to closing the sheave 22 to a minimum is prevented. Be prepared to maintain grain sorting capacity. When the sheave 22 is opened with a small amount of objects to be processed on the swinging shelf 21 and the Karin breeze is too strong, the grains are blown without falling into the spiral 25 first and discharged out of the machine from the rear of the machine. However, in the present embodiment, the above-mentioned grain is prevented from being discharged outside the machine.

As described above, in this embodiment, it is possible to prevent excessive accumulation of the object to be processed on the swinging shelf 21, clogging of the sheave, and damage to the swinging shelf 21 due to overload, and to improve the ability to sort the object to be processed. Thus, an extremely excellent effect for improving the performance of the threshing device 15 can be exerted.

Embodiment 2 In this embodiment, in the threshing apparatus 15 in which the opening of the sheave 22 and the opening of the shutter of the Karamin 39a are both adjustable, a flow rate sensor 48 is provided in addition to the on-shelf volume sensors 49, 49. The control is performed by estimating the deposition height of the processing object on the swinging shelf 21 using the detection value of the flow rate sensor 48 in the same manner as in the first embodiment, except that the on-shelf volume sensors 49 and 49 and the flow rate The sensitivity of the sensing sensor 48 is increased to transmit the on-shelf volume sensor 49, the detected value high of the 49 and the detected value of the flow rate sensor 48 at a lower specified value than in the first embodiment, and the sheave 22 to be controlled is opened. And the opening of the shutter of Kara Mina 39a are different.

In this embodiment, as shown in FIG. 4, the sheave 22 of the threshing apparatus 15 and the karino 39 of the threshing apparatus 15 are performed by using two types of detectors: a volume sensor 49 on the shelf and a flow rate sensor 48.

An opening of 39k and 391 is set. Here, as an example, it is assumed that there are five stages of shutter opening, and the second stage is set. In step s3, select between manual operation and automatic operation,
If it is a manual operation, the operation proceeds to step s4, and the operation is continued at the third stage of the opening of the sheave 22 and the second stage of the Karino shutter opening which were previously set. If necessary, the sheave 22 and the Karino shutter opening are changed by changing the sheave opening setting dial and the Karano shutter opening setting dial to continue the manual operation.

When automatic is selected in step s3, the process proceeds to step s205, in which the flow rate sensor 48 detects the flow rate of the kernel passing through the second processing chamber end portion 27a and determines whether the detected value is higher than a specified value. Then, if NO, the process proceeds to step s206, where the pile height of the objects to be processed (such as grains and straw chips) that have fallen and accumulated on the swing shelf 21 is determined by the handling net 34 and the on-shelf volume sensors 49, 49. It is determined whether or not the detected value is higher than the specified value. If NO, the process proceeds to step s207 to open and close the opening of the sheave 22 to the dial set value (here, the third stage), and then to step s20.
Proceeding to step 8, after opening and closing the Karino shutter opening to the dial set value (here, the second stage), proceeding to step s209, checking the operation of the threshing device 15, and if YES, the timer of step s210 is used to determine the elapse of a certain time. Waiting step s
Return to 205. If the operation of the threshing device 15 is NO in step s209, the process proceeds to step s211 and the operation of the threshing device 15 is stopped.

If YES in step s205, the flow advances to step s214 to detect the height of the object deposited on the swinging shelf 21 by the on-shelf volume sensors 49, 49. If it is not too high, the process proceeds to step s215 to open the sheave 22 one step (here, the fourth step), and then close the Karino shutter opening one step (the first step).

If the height of the object to be processed deposited on the swinging shelf 21 in step s214 is higher than the specified value, the flow advances to step s217 to open the sheave 22 by one step (here, the fourth step). ), And then proceeds to step s218 to open the Karino shutter opening one step (here, the third step).

NO in step s205, step s20
If YES in 6, proceed to step s212 and sheave 22
Is closed in one stage (here, the second stage), and the process proceeds to step s213 to open the Karino shutter opening one stage (here, the third stage).

FIG. 8 shows a control flow of the present embodiment, and a description thereof will be omitted.

Embodiment 7 This embodiment is a combination of Embodiments 1 and 6. That is, in addition to the on-shelf volume sensors 49 and 49 for detecting the height of the object to be processed on the swinging shelf 21, a flow rate sensor 48 for detecting the flow rate of the grain passing through the second processing chamber end portion 27 a is provided. Although the control is performed by predicting the deposition height of the workpiece on the swinging shelf 21 using the detection value of the sensing sensor 48 as in the first and second embodiments, the on-shelf volume sensors 49, 49 are provided. And the flow rate sensor 48 is capable of transmitting third, low, middle and high detection values, respectively, or two sets of on-shelf volume sensors 49, 49 and flow rate sensors 48 having different sensitivities are provided.

725) indicates that the flow rate of the kernel passing through the second processing chamber end portion 27a is equal to or more than the specified value. After the lapse of time, it can be predicted that the height of the object to be processed on the swinging shelf 21 will increase. Therefore, the sheave 22 is opened in two stages to facilitate the passage of grains, and the opening of the Karamin shutter is increased by one. The stage is opened to increase the amount of air blown by the Kara Mina 39a to increase the grain sorting ability, and control is performed to prevent the pile height of the processing object on the swinging shelf 21 from becoming excessive at the next point in time. .

When the on-shelf volume sensor 49 is equal to or more than the specified value and the flow rate sensor 48 is less than the specified value (steps s716 and s717), the kernel passing through the terminal end 27a of the second processing chamber 27 Indicates that the flow rate of the object is less than the specified value.
Since it can be predicted that the upper height of the material to be treated is reduced, the opening of the sheave 22 is closed to a minimum to loosen the passage of grains, and the opening of the Karino shutter is opened to the maximum to open the sheave 22 In order to prevent a decrease in the amount of air blown by Karino 39a due to the closing of the tray, the grain sorting capacity is maintained, and at the next point in time, the pile height of the workpiece on the rocking shelf 21 becomes too small and the grain sorting is performed.

9, step s720) indicates that the flow rate of the kernel passing through the terminal end portion 27a of the second processing chamber 27 is equal to or more than the specified value (medium). Even if the pile height is low, the pile height of the object to be treated on the rocking shelf 21 can be expected to increase to a moderate level after a short time, so that the sheave 22 is opened one step to make the passage of kernels slightly easier. At the same time, in order to prevent the fluid resistance from decreasing due to the increase in the opening of the sheave 22, and to prevent the amount of air blown by the Karino 39a from becoming excessive, control is performed to close the Karino shutter opening by one step, and to swing at the next point in time. Control is performed in advance to prevent the processing object accumulation height on the shelf 21 from becoming excessive.

When the on-shelf volume sensor 49 is equal to or more than the specified value (medium) and the flow rate sensor 48 is less than the specified value (steps s714 and s715),
Since the flow rate of the grain passing through the terminal end portion 27a of the second processing chamber 27 is less than the specified value,
Even if the upper height of the object to be processed is moderately high, the height of the object to be processed on the swinging shelf 21 can be predicted to decrease after a short time, so that the sheave 22 is closed by one stage to open the grain. The passage of the grains is moderated, and the opening of the Karino shutter is opened in two stages, and the opening of the sheave 22 is closed in one stage, so that the airflow of Karino 39a is prevented from decreasing and the grain sorting ability is maintained. At the next point in time, control is performed in advance to prevent the height of the pile of objects to be processed on the swinging shelf 21 from becoming too small and the grain sorting ability from decreasing.

Embodiment 8 In this embodiment, in addition to the on-shelf volume sensors 49 and 49 for detecting the height of the object to be processed on the swinging shelf 21, the flow rate of the kernel passing through the second processing chamber end 27a is determined.

The sensitivity of the upper volume sensors 49, 49 and the flow rate sensor 48 is increased, and the detected value height of the on-shelf volume sensors 49, 49 and the detected value height of the flow rate sensor 48 are transmitted at a lower specified value compared to the first embodiment. The second embodiment differs from the second, fourth, and sixth embodiments in the opening degree of the sheave 22 to be controlled and the opening degree of the shutter of the Karamin 39a.

FIG. 10 shows the control flow of this embodiment. Embodiment 9 This embodiment is a combination of Embodiments 1 and 8. That is, in addition to the on-shelf volume sensors 49 and 49 for detecting the height of the object to be processed on the swinging shelf 21, a flow rate sensor 48 for detecting the flow rate of the grain passing through the second processing chamber end portion 27 a is provided. Prediction of the height of the object to be processed on the swinging shelf 21 using the detection value of the sensing sensor 48 is performed in the same manner as in the first to eighth embodiments, but the on-shelf volume sensors 49, 49 are used. And the flow rate sensor 48 is capable of transmitting third, low, middle and high detection values, respectively, or two sets of on-shelf volume sensors 49, 49 and flow rate sensors 48 having different sensitivities are provided.

When the increase in the grain flow rate is detected, the increase in the accumulation height of the processing object on the swinging shelf 21 at the next time is controlled prior to the detection of the on-shelf volume sensor 49,
Since the opening degree of the sheave 22 and the opening degree of the shutter of the Kara Mina 39a are finely predicted and controlled, an excessive accumulation of the object to be processed on the swinging shelf 21, clogging of the sheave, and overload of the swinging shelf 21 due to overload.
