A processing blade 28 is provided, and the lower side of the second processing cylinder 26 is mainly surrounded by a second processing net or a non-porous second processing gutter 29.

The above-mentioned dust-treating cylinder 19 and the second treating cylinder 26 are provided coaxially, but the constitution is arbitrary. For example, the dust-treating cylinder 19 and the second treating cylinder 26 Fitting bodies 31 and 32 are respectively provided on the starting end sides, and fitting shafts 33 and 34 that are spline-connected to the fitting bodies 31 and 32.

The second processed material discharge port 46 faces the transfer shelf 11 at the start end of the swing sorting shelf 10. Thus, the second processing chamber 25
An object to be processed amount detecting means 50 is provided therein. The processing object amount detecting means 50 is configured to identify the grain and the straw waste by electromagnetic waves or the like and also to detect the amount of the grain, and the second processing is performed from the upper discharge port 47 of the second return device 27. It may be provided between the material discharge ports 46. Also, the sheave 13 of the swing sorting shelf 10
A layer thickness detecting means (layer thickness sensor) 51 for detecting the thickness of the layer of the object to be processed on the sheave 13 is provided above the sheave 13. The layer thickness detecting means 51 may be configured to detect the angle of the arm that comes into contact with an ultrasonic sensor, straw waste, or the like by using a potentiometer. Then, the processing object amount detecting means 50 and the layer thickness detecting means 51 are connected to a control section 52 to control the threshing apparatus 1. The processing object amount detecting means 50 sets “small” when the amount is smaller than the preset kernel amount, and “large” when the amount is larger than the predetermined amount of grain, and the layer thickness detecting means 51 sets the standard processing capacity of the swing sorting shelf 10 to On the other hand, when the thickness of the object to be processed is thin, it is defined as "small", and when it is thick, it is defined as "large". In accordance with signals from the processing object amount detecting means 50 and the layer thickness detecting means 51, each part of the threshing apparatus 1 (the number of rotations of the blowing fan 8; the inclination of the sheave 13; the number of rotations of the second processing cylinder 26; (The number of oscillations, amplitude, etc. of 10) are controlled to operate optimally.

FIG. 5 shows an example of this. FIG. 5 shows the operation of the air blower 8, the sheave 13, and the second processing cylinder 26 based on the detection values of the processing object amount detecting means 50 and the layer thickness detecting means 51. In order to facilitate the description, one or both of the detected values of the object amount detection means 50 and the layer thickness detection means 51 and the control state are shown in one column from the top in order to facilitate the description. , 2 columns, 3 columns, the bottom column is 4
Columns (hereinafter the same), and the respective columns of the blower fan 8, sheave 13, and second processing cylinder 26 will be described. The blast of Karino 8 is designed to harmonize the reduction of threshing load with the improvement of sorting accuracy.
In column 3, where the processed material amount detection means 50 became large, the "current status" was set, and in column 4, the air blowing was reduced by one step to prevent the grains from flying, thereby improving the sorting accuracy. In columns 2 and 3, the blower is further increased to reduce the threshing load.

[0011] In this case, the blowing of the blowing fan
If it can be adjusted in five stages, depending on various conditions such as the state of the sheave 13 and the second processing cylinder 26 and the running speed, which will be described later, the detection values of the processing object amount detecting means 50 and the layer thickness detecting means 51 are in the same three columns. Even if it is applicable, the second-stage or fourth-stage ventilation may occur. Therefore, the comparison data of the “current” is updated every predetermined time. In the middle of the third stage, when the air is blown by the blower Karin8, the first stage is the fourth stage, and the fourth stage is the second stage. In some cases, the processing object amount detecting means 50 and the layer thickness detecting means 51 may be provided in three columns, and in this case, the comparison data is updated and the processing object amount detecting means When the column 50 and the layer thickness detecting means 51 are in the first column, It is configured to so that.

When the sheave 13 is opened, the falling amount increases to reduce the threshing load, and when the sheave 13 is closed, the falling amount decreases to prevent the mixing of straw chips and improve the sorting accuracy.
When the opening 3 is opened, the processing object amount detecting means 50 becomes large.
If the sheave 13 is opened when the detection value of the object amount detection means 50 is large, as in the case of opening the sheave 13 in the column, the capacity of the second processing chamber 25 is exceeded. (In the first column, the layer thickness detecting means 51 is also large, so closing the sheave 13 exceeds the capacity of the swing sorting shelf 10, so that the sheave 13 is not moved, and the other air blower 8 and the second processing cylinder are not moved. 26), whereas 2
In the column, the amount of object-to-be-processed detecting means 50 is small, so that it is opened by one step to increase the amount of drop. Conversely, in the column 3, the amount of object-to-be-processed detecting means 50 is large, so that it is closed by one step to reduce the amount of drop. In the four columns where the layer thickness detection means 51 are both small, there is a margin in the processing capacity of the second processing chamber 25. In order to increase the supply amount of the second product to the second processing chamber 25,
Open one step to increase the amount of fall, and improve the processing accuracy and efficiency of the attached particles of branch stumps.

[0013] The sheave 13 is also opened by blowing air
Like the air blow of, for example, if you adjust in five stages,
Even if it corresponds to the same one column, the opening degree of the second step or the opening step of the fourth step may occur.
If the column is open at the middle third stage among the five stages, the fourth column is set for the second column, and the second column is set for the third column. When the opening degree of No. 13 remains at the fourth level and the processing object amount detecting means 50 and the layer thickness detecting means 51 become one column, the comparison data is updated, and the processing object amount detection is performed for the opening degree of the fourth step. Means 5
When the 0 and the layer thickness detecting means 51 are in the second column, the air is blown to the fifth stage, or when the processed object amount detecting means 50 and the layer thickness detecting means 51 are in the third column, the opening is three steps, or the processed object amount detecting means is used. When 50 and the layer thickness detecting means 51 are in four columns, they are opened in five steps.

When the rotation speed of the second processing cylinder 26 is increased, the processing efficiency is improved and the threshing load is reduced. When the rotation speed is lowered, the processing accuracy is improved. The two columns of the object quantity detecting means 50 are set to the “current state” in the two small columns (the rotation of the object to be processed amount detecting means 50 is large because the layer thickness detecting means 51 is large, so that the rotation is not dropped). In column 3, since the amount of object to be detected 50 is large, the rotation of the first stage is increased, and in column 4, the rotation is reduced to prevent prolapse and to process the branch branch. The rotation of the second processing cylinder 26 is also the same as that of the blower fan 8. When the rotation speed is the middle third stage among the five stages in the second column, 5 in the first and third columns. Although the predetermined number of times have passed and the rotation speed remains at the fourth level due to other conditions, the object amount detection means 50
When the layer thickness detecting means 51 has two columns, the comparison data is updated, and when the object amount detecting means 50 and the layer thickness detecting means 51 have one column and three columns with respect to these four stages of rotation speed, five columns are obtained. The number of rotations of the eyes,
When 0 and the layer thickness detecting means 51 have four columns, the rotation speed is set to three stages.

When the air blower 8, the sheave 13, and the second processing cylinder 26 are all at the fifth stage, and the processing object amount detecting means 50 and the layer thickness detecting means 51 are large, the traveling speed is reduced. Take the measures of. According to the embodiment of adjusting the angle of the sheave 13, a plurality of the plate-like fins 53 intersecting with the swing direction are arranged in the swing sorting shelf 10 in the swing direction. A mounting shaft 54 is fixed to the upper end, and both ends of the mounting shaft 54 are mounted on the swing sorting shelf 10, and the inclination angle of the fins 53 is adjusted by rotating the mounting shaft 54.
An engaging shaft 55 is fixed to the lower end of each fin 53, and the engaging shaft 55 is engaged with a long hole 56 provided in the swing sorting shelf 10. To the shaft. Any one or more of the fins 53 may include
An arm 58 is fixed to the mounting shaft 54 and the engagement shaft 55, and the arm 58 and the arm 61 of the sheave angle adjusting motor 59 are interlocked by a connecting member 62 such as a wire. 63 indicates each arm 58 when a plurality of arms 58 are provided.
, 64 is a traction spring, 65 is an arm 5
A switch or a sensor for detecting the position 8.

The sheave 13 has a different configuration below the threshing chamber 2 and the second processing chamber 25. For example, on the side below the threshing chamber 2, there is provided a jagged fin 53a having a jagged upper surface. The upper surface of the fin 53 on the second processing chamber 25 side is formed flat. Then, the second return device 27
A partition plate 66 is provided between the upper discharge port 47 and the threshing chamber 2 in order to prevent grains and the like scattered from the upper discharge port 47 from entering the threshing chamber 2. Further, the partition plate 66 may be provided in a part of the handling net 7 (FIG. 13). Also, the dust treatment chamber 1
8 is replaced by a casing 67 having a lattice shape in the vertical and horizontal directions, and a leakage port 68 is provided in the casing 67. The lower part of the dust treatment chamber 18 is provided with a closed portion 69 in the axial direction to discharge the dust. Leakage below the dust treatment chamber 18 is prevented to prevent bias, and a leakage guide 70 is provided at each of the fallout openings 68 of the casing 67 to expect diffusion of the processed material. Also,
The leak opening 68 is formed such that the opening area thereof is larger on the upper side and smaller on the lower side (H> H ₂ > H ₃ ), and the diffusion of the processed material is expected (FIG. 14). Further, an extension 71 of the casing 67 is provided below the dust treatment chamber 18 so that the dust outlet 24 is opened to the side, thereby preventing the dust treatment cylinder 19 from taking in straw and grains. 16).

The culm supply port 72 of the threshing chamber 2
In the path leading to, a visual sensor 73 is provided, and it is possible to identify the color of the cereal culm by the visual sensor 73 to identify the growth status, that is, to identify the culm and the tip by the color and shape, The so-called grain percentage is detected, and the rotation of the processing cylinder is controlled. In the embodiment, it is presumed that the closer the color is to green, the higher the water content is. The higher the specific gravity of a rice plant with a higher water content, the more the reduction of the second color tends to increase.
After a certain period of time has elapsed since the detection of No. 3, control is performed to increase the rotation speed of the second processing cylinder 26. Further, the grain ratio is added to the condition, and the air blower 8, the sheave 13, and the second processing cylinder 26 are controlled as in the control embodiment. Fig. 2 shows an example.
2. As shown in FIG. 23, FIG. 22 shows a case where the grain ratio is small.
Even if it is estimated that the second reduction will increase and the layer thickness detecting means 51 detects that the thickness is thin, the current rotation is maintained not only in the third column but also in the fourth column. Further, when the layer thickness detecting means 51 detects that the layer is thick, it is estimated that the second reduction is further increased, and the blowing is strengthened by two stages.

The control of the sheave 13 and the second processing cylinder 26 is the same as in the above embodiment. FIG. 23 shows a case where the grain ratio is large, and when the layer thickness detecting means 51 detects that the layer thickness is small, the blowing of the air blower Karin 8 drops the one-step air blowing from the normal setting, and when the layer thickness detecting means 51 thickens the layer. When it is detected, it is increased step by step. The sheave 13 and the second processing cylinder 26
Is the same as in the previous embodiment. In the figure, 74 is a combine body frame, 75 is a traveling device, 76 is a mowing section, 77 is a weeding body, 78 is a cereal culm transport device, and 79 is a cereal culm that supplies the ear end side of the cereal culm to the threshing room 2. Supply and transport device, 80
Is a cutter for finely cutting the threshed waste straw, 81 is a Glen tank provided on the side of the threshing room 2, 82 is a discharge / fryer, 83 is a discharge auger, 84 is a cabin, and 85 is a grain culm.

[0019]

Next, the operation will be described. When the cereals are supplied to the threshing room 2, they are threshed by the rotating handling drum 3 in the threshing room 2, and the threshed grains fall from the handling net 7 onto the transfer shelf 11 of the swing sorting shelf 10, and are transferred. 11 are transferred by the transfer projections 12 to the wind selection chamber 9, and on the sheave 13 of the swing sorting shelf 10,
By the oscillating sheave 13 and the air blown by the air blower 8, the straw chips and the grains are separated, and the grains fall from the gaps of the sheave 13 and are taken out of the conveyor 15 first. Also,
Threshing objects which do not fall from the handling net 7 enter the dust processing chamber 18 through the communication port 23 at the end of the threshing chamber 2 and are processed and processed by the dust processing blade 20 of the rotating dust processing cylinder 19. The kernels fall down from the dust treatment net 21 and
Straw, etc., which is selected by air in the wind selection chamber 9 and does not fall from the dust treatment net 21, falls from the dust discharge port 24, and the grains in the straw are dropped by the wind screening, and the straw is discharged outside the machine. Is done.

In this case, since the dust processing chamber 18 is provided on the side of the handling cylinder 3 below the handling cylinder shaft 4, the dust processing chamber 1 is provided.
Exhaust particles efficiently enter and are treated within 8. That is, the thresh in the threshing chamber 2 tends to gather obliquely downward with respect to the handling cylinder shaft 4 due to the action of the centrifugal force that rotates together with the gravity and the rotation of the handling cylinder 3, and By arranging the dust treatment chamber 18 on the side of the body 3, the supply to the dust treatment chamber 18 is facilitated. Moreover, since the straw waste does not fall from the gap of the sheave 13, it moves to the discharge side by the swinging of the swing sorting shelf 10 and the blowing of the blasting wind of Minami 8. The straw dust is sucked out by the suction / dust fan 17 and the straw dust that is not sucked by the suction / dust fan 17 reaches the straw rack 14, and the straw dust that does not fall from the straw rack 14 is discharged outside the machine.

However, among the fallen objects dropped from the sheave 13, ear breaks, spike sticking particles, etc., do not fall from the sorting net 86, but swing on the swing sorting shelf 10 and the sorting wind to separate the sorting net 86. It moved to the terminal end side, dropped into the second trough from the opening between the terminal end of the sorting net 86 and the swing sorting shelf 10, and fell off by the swing of the straw rack 14, and spikes and spikes attached. The particles are returned to the threshing room 2 or the processing room by the second return device 27 via the second conveyor 16 and reprocessed together with the grains. The spikes, spikelets and the like attached by the swing of the swing sorting shelf 10 are collected by the second conveyor 16 and sent from the end of the second conveyor 16 to the second processing chamber 25 by the second return device 27. Can be The second processing chamber 25 sends the second product to the starting end side of the threshing chamber 2 by the second product processing blade 28 of the rotating second processing cylinder 26, and processes the second product while feeding the second product. The grain and the second processed material fall from the second processed material discharge port 46 onto the transfer shelf 11 of the swing sorting shelf 10 and are again sorted by the swing and the wind.

Since the fins 53 of the sheave 13 can be freely changed in angle between a substantially vertical standing position and an inclined position,
When the threshing amount is large and the load is large, the load accumulates on the sheave 13, so that the fins 53 are erected to widen the gap between the fins 53 so that the grains fall quickly.
The fins 53 are inclined to reduce the falling of the waste. The fins 53 energize a sheave angle adjusting motor 59,
The sheave angle adjusting motor 59 rotates the arm 61 to loosen the connecting member 62, and the arm 58 is connected to the traction spring 6
4 and the arm 58 rotates to attach the mounting shaft 54.
Is rotated, and the fin 53 is opened and closed by the rotation of the mounting shaft 54, and the rotation of the fin 53 is stopped by the engagement shaft 55 hitting the slot 56.

Further, although the illustration of the blowing fan 8 is omitted,
The rotation speed is changed to change the air volume (wind force), and the second processing cylinder 26 also changes the rotation speed to change the processing capacity. In this case, in the second processing chamber 25, a processing object amount detecting means 50 capable of detecting the amount of the processing object is provided.
A layer thickness detecting means 51 for detecting the thickness of the layer of the workpiece on the sheave 13 is provided at a position above the sheave 13, and the detection values of the workpiece quantity detecting means 50 and the layer thickness detecting means 51 are used as a reference. Control, the current threshing load can be controlled by estimating the magnitude of the current threshing load, which part of the load is large, and the future load transition, improving control accuracy and reducing threshing loss. Improve work efficiency.

In this embodiment, however, the air blower 8, the sheave 13, and the second processing cylinder 26 are controlled based on the detection values of the processing object amount detecting means 50 and the layer thickness detecting means 51.
Each other acts to improve on each other's performance limits, keeping the overall performance at an optimum. That is, as in the example shown in FIG. 5, the threshing chamber 2, the swing sorting shelf 10, the dust-extraction chamber 18, and the entire threshing apparatus 1 are still based on the detection values of the processing object amount detecting means 50 and the layer thickness detecting means 51. When the load is small (column 4 in FIG. 5), the blower Karin 8 weakens the blower to prevent the scattering of grains, and the sheave 13 is opened to open the second processing chamber 2.
5, the rotation of the second processing cylinder 26 is reduced, the accuracy of the second processing chamber 25 is improved, and the threshing loss is reduced.

When the object amount detecting means 50 is large (columns 1 and 3), the sheave 13 is not expanded or closed to reduce the return to the second processing chamber 25 to reduce the load. When the layer thickness detecting means 51 is large, the blowing of the blowing fan 8 is increased (columns 1 and 2). As shown in the third column, if the future load increase is estimated by the processed object amount detecting means 50 even if there is a margin from the detection value of the layer thickness detecting means 51, the blowing of the blowing fan 8 should be weakened. And maintain the status quo. Similarly, the number of rotations of the second processing cylinder 26 in the second column is also estimated that the amount of the second product returned to the second processing chamber 25 is large.
Maintain the status quo without dropping rotation. Thus, by comparing the signals sent from the processing object amount detecting means 50 and the layer thickness detecting means 51 while updating them at predetermined time intervals, it is possible to accurately grasp the situation of the threshing apparatus 1 and the changing state. To maintain overall performance at optimal levels.

The sheave 13 has a different configuration below the threshing chamber 2 and the second processing chamber 25. For example, the lower part of the threshing chamber 2 is formed in a jagged shape, so that the transfer of straw waste is good. On the other hand, the second processing chamber 25 side is formed flat because the falling amount of the straw waste is small, and the wind selection accuracy can be improved. Thus, the upper outlet 47 of the second return device 27
Since the partition plate 66 is provided between the threshing room 2 and the threshing room 2, it is possible to prevent the grains scattered from the upper discharge port 47 from entering the threshing room 2 and to prevent threshing. Also, if the partition plate 66 is provided in a part of the handling net 7, the cost is reduced.

[0027]

The present invention has a threshing chamber 8 having a handling cylinder 9, a swing sorting shelf 10 for sorting threshing products, and a second processing chamber 25 for processing a second product. A layer thickness detecting means 51 for detecting the layer thickness of the object on the shelf is provided above the shelf 10, an object amount detecting means 50 for the second processing chamber 25 is provided, and the layer thickness detecting means 51 and the object amount are provided. Since the threshing apparatus is controlled by the signal of the detection means 50, it is possible to perform control by estimating the current threshing load, which part is large, and estimating the future load transition. The present invention has the effect of improving the accuracy of threshing control, reducing threshing loss, and improving work efficiency. That is, not only the current threshing state but also the subsequent threshing state is predicted by the signals of the two systems of the detecting device of the layer thickness detecting means 51 and the amount-of-processed-objects detecting means 50, and it is always optimal by responding in advance. The most effective control can be executed by setting the control state and controlling the threshing device comprehensively by the signals of the two detection devices 50 and 51.
