A configuration that performs engine rotation control, vehicle speed control, opening control of chaff sheave (selection interval), control of increase / decrease of Karatsu output (selection air volume), etc., alone or in combination with control signals from I'm taking it.
[0003]
[Problems to be solved by the invention]
In the conventional threshing machine described above, various threshing / sorting controls are performed based on the detection information of the sensor, and the chaff sieve sorting interval is automatically selected (expanded / narrowed) according to the grain flow rate during processing. Adjustment) and automatic selection (increase / decrease adjustment) of the selection air volume of tang. In the threshing machine, the dust-removing material swings from the fateful configuration that must be provided at the side of the handling chamber at the upper side of the sorting chamber and located one side away from the plan view. There is a structural problem that tends to fall to one side of the sorting shelf and the tendency becomes stronger as the grain flow rate increases.

[0014]
Next, the control means 5 using a microcomputer (hereinafter referred to as “controller 5”) will be described.
As shown in FIG. 1, the controller 5 has an automatic switch 44 and a grain sensor S1 connected to the input side, and an actuator M1 (hereinafter referred to as "shift control motor M1") on the output side. And a dust control motor M2 are connected to each other. When the automatic switch 44 is turned ON, the controller 5 enters an execution state, and is input from the preset control mode and the data (reference value) input and stored and the grain sensor S1. The shift control motor M1 is shift-controlled by an operation signal that is output while being compared with the detected information to control the operation of the dust control motor M2. In the case of the present invention, the shift control motor M1 controls from the controller 5 to the speed increasing side when the detection information input from the grain sensor S1 reaches the grain flow rate exceeding the reference value. A signal is output.
[0015]
In addition to the above sensors, the actual combine includes a grain sensor, a vehicle speed sensor, an engine rotation sensor, a sensor comprising a potentiometer for detecting the shift position of the hydraulic transmission, a red rotation sensor, and a chaff opening sensor. Etc. and various control devices are provided, but in the embodiment, only the configuration necessary for the explanation of the present invention is described, and the others are omitted.
[0016]
Next, the operation will be described.
First, the engine is started to prepare for work while driving the rotating parts of the machine body. At that time, the automatic switch 44 is turned on, and the controller 5 is brought into an execution state to complete the preparation.
Then, when the combine is advanced while driving the traveling device 6, the rice straw in the field is harvested by the harvesting device 9 of the front cutting pretreatment device 11 in accordance with the advancement of the traveling vehicle body 7. Is transported upward by the action of the above, passed to the feed chain 26 and supplied to the threshing machine 8. The cereal is supplied in a state where the tip portion is inserted into the handling chamber 13 from the handling port 27 while being held by the feed chain 26 and conveyed, and the threshing action is exerted by the rotating handling cylinder 12. receive. In this way, the threshing that has been subjected to the grain removal treatment is carried around the inside of the handling chamber 13 by the rotating handling cylinder 12, and further leaks from the sorting net while receiving the grain removal treatment action, and the sorting chamber 1. Reaches the swing sorting shelf 14 and receives the swing sorting action.
[0017]
Then, the object to be sorted is transferred on the transfer shelf 28 in the direction of the shelf tip and reaches the chaff sheave 29, and the grains and the like leak and are separated and separated from the long bean cake. At this time, the Kara 15 is transmitted and rotated, wakes up the sorting wind and blows it into the sorting chamber 1, and performs the wind sorting action on the above-described objects to be sorted. The dust is separated into a dust that reaches the suction dust collector 31 and a dust that reaches the shelf tip straw rack 30 of the swing sorting shelf 14 and is discharged to the outside.
[0018]
In this way, the objects to be sorted are sorted while receiving the cooperative action of the rocking sorting action and the wind sorting action by the sorting wind, and sorted into the first thing (fine grain), the second thing, and the dust. The first thing falls on the first transfer spiral 16 and is collected and harvested outside the machine, and the second thing is collected in the second transfer spiral 17 and cerealed by the second cerealing device 19 from the end. Then, it is returned to the second treatment chamber 3 and subjected to the second treatment action, and the dust is discharged by the suction dust removal device 31, and the waste that has reached the straw rack 30 is discharged from the shelf tip to the outside of the machine. Be dusted.
[0019]
On the other hand, the unprocessed material carried around by the rotating barrel 12 remaining in the handling chamber 13 without leaking into the sorting chamber 1 passes through the intake port 22 from the end portion of the handling chamber 13 and is discharged. It is sent to the dust processing chamber 18. At this time, since the dust is disposed in the embodiment in which the dust removal cylinder 25 and the handling cylinder are interlocked (see FIG. 6), the inheritance from the handling chamber 13 to the dust disposal chamber 18 is extremely difficult. Can be smooth. In this way, the dust discharged into the dust processing chamber 18 is sent while receiving a processing action by the dust processing cylinder 25, and what can be leaked on the way from the leaking frame 23 to the sorting chamber 1 sequentially. The dust that has leaked and reaches the dust outlet 24 is dropped into the sorting chamber 1.
[0020]
Now, during the threshing / sorting operation as described above, the controller 5 performs the second processing control based on the detection information input from the grain sensor S1 equipped in the second processing chamber 3. Yes.
That is, the controller 5 compares the detection information input from the grain sensor S1 with a reference value stored in advance in the microcomputer, and controls the shift control motor M1. Is output to perform shift control. And the controller 5 increases the quantity of the 2nd thing supplied from the 2nd cerealing device 19 in the 2nd process chamber 3, and the grain flow volume jumped up by the spreading | diffusion blade 21 increases, and grain. When the numerical value based on the detection information input from the sensor S1 exceeds the reference value, an acceleration control signal is output to the shift control motor M1. Therefore, the transmission 4 is operated to shift from the shift control motor M1 to the speed increasing side, and shifts the second processing cylinder 2 to the speed increasing rotation side.
[0021]
In this way, since the processing capacity of the second processing cylinder 2 increases when the speed is increased, the second processing cylinder 2 acts on the second object carried around in the second processing chamber 3 and efficiently processes it. Then, reprocessing while branching off the shoots adhering properly. Then, the diffusion blade 21 diffuses the dust in a wide range while being rotated at a high speed at the terminal portion of the second processing cylinder 2 and above the dust outlet 20 and discharges it to the sorting chamber 1. Accordingly, the dust is uniformly diffused and dropped without being shifted to the upper surface of the transfer shelf 28 of the swing sorting shelf 14, and the subsequent sorting action is effectively performed.
[0022]
Further, as described above, the dust discharge adjusting plate 32 increases in response to a signal output from the controller 5 when the numerical value based on the detection information input from the grain sensor S1 exceeds the reference value. Dust removal control is performed via a dust removal control motor M2. In other words, the dust control plate 32 is tilted to the side that facilitates the dust transfer by automatically adjusting the tilt direction (angle) from the dust control motor M2 via the operating rod 34, and feeds the dust. Will be better. Further, the dust control plate 32 is controlled in an inclination direction (angle) that brakes the transfer of dust when the grain flow rate is small compared to the reference value. In this way, the dust removal adjustment plate 32 can automatically perform dust removal adjustment according to the amount of the second object in the second treatment chamber 3 and can perform an effective second treatment action.
[0023]
As described above, the second processing chamber 3 controls the rotation of the second processing cylinder in accordance with the grain flow rate in the room and performs the second processing action according to the actual state. The falling dust particles can be diffused over a wide range and can be properly sorted without any deviation on the swing sorting plate 14.
The second processing cylinder 2 and the dust processing cylinder 25 are configured as shown in the embodiment (see FIGS. 6 to 8), so that the transmission mechanism can be simplified and the cost can be reduced, and the attachment and detachment is easy. Thus, a practical effect that can improve maintenance can be achieved.
[0024]
