  The present invention relates to an electric combiner that uses a prime mover and an actuator together as a driving source of a vehicle. More specifically, the traveling unit is driven by the power of the actuator, and the working unit is an actuator driving unit that is driven by the power of the actuator. A drive unit that is driven by the power of the prime mover, each drive source of the traveling unit and the actuator drive unit is provided with a detector that detects each drive speed, and each detector is connected to the controller, and The controller relates to an electric combine that controls an inverter connected to a corresponding actuator based on detection information of each detection.

  A conventional combine (agricultural work vehicle) is driven by the driving force of an engine as a prime mover mounted on a vehicle body from a plurality of processing units such as a crawler or a traveling unit of a crawler or a cutting and threshing through various mechanical power transmission mechanisms. Was driving the working part. In recent years, however, environmental problems have been emphasized, and air pollution reduction and fuel economy savings have been increasing. As a power source, a hybrid combine in which an engine and an electric motor are mounted on a vehicle has been proposed. This is because the vehicle has two drive sources, an engine and an electric motor, and uses them properly to reduce exhaust gas and improve fuel efficiency. As an example, the vehicle is equipped with an engine, a generator, a battery, an electric motor provided in the processing section, etc., and the driving section of the vehicle is driven by the power of the engine. There is one that supplies the electric power to the electric motor via a battery and drives a working unit such as a reaping device or a threshing device (for example, Patent Document 1).

  In addition, as a working part, an auxiliary output motor is provided in the handling cylinder separately from the engine that drives the handling cylinder of the threshing part, and when the vehicle speed linked to the driving of the handling cylinder is reduced, it is already cut off. Since the cereals that are being carried are transported to the threshing section as they are, the transport amount is not reduced, and if the handling cylinder is overloaded, the auxiliary output motor is operated and the auxiliary output motor cooperates with the engine. Then, there is one that drives the handling cylinder and performs assist control of the handling cylinder (for example, Patent Document 2).

  In a combine like the above-mentioned patent document 1, an electric motor is used as a drive source of a working part, and especially a handling cylinder in a threshing part is driven by an electric motor that operates using electric power generated by a generator. However, since this handling cylinder has weight and rotates by winding or pinching a large amount of cereals around the handling teeth, it has a large output equivalent to about 50 to 60% of the total output in the drive system of the entire combine. In the electric motor described above, such a handling cylinder cannot be driven to rotate sufficiently, and the work efficiency is significantly reduced, such as stopping the rotation of the handling cylinder, and clogging of the cereal grains in each working part.

As a result, the traveling unit that cooperates with the harvesting unit reduces the vehicle speed. And, following the decrease in vehicle speed, the feeding speed of the feed chain that transports the harvested cereals at the threshing section is also reduced, so that the cereal grains that have been harvested in large quantities at the harvesting section are clogged with the feed chain, There is a problem that maintenance is required and workability is deteriorated.

  Moreover, in the combine like patent document 2, the drive source of all the driving | running | working parts and working parts is covered with the driving force of one engine, and the handling cylinder which requires a big output as mentioned above is driven with this engine. In order to achieve this, the output of the engine cannot be reduced, and as a result, the engine cannot be reduced in size. Furthermore, the battery is charged with low-voltage power generated by an alternator or the like, and the auxiliary output motor using this power has a problem that the handling cylinder cannot be rotated sufficiently.

  The threshing unit electric motors M4a and M4b for driving the waste transporting chain 20 and the suction fan 50 of the waste processing unit 11 are provided with detectors D4a and D4b constituting the detector D4, respectively. A detector D5 is attached to the threshing unit electric motor M5 that drives the unit 16.

  Furthermore, detectors D6a and D6b constituting the detector D6 are installed in the traveling unit electric motors M6a and M6b that drive the traveling unit 3, respectively.

  For the detectors D1 to D6, for example, known speed detectors such as a rotary encoder and an octopus generator can be used as appropriate. The detectors D1 to D6 are installed in the vicinity of the electric motors M1 to M6, and the drive shafts of the electric motors M1 to M6 The rotational speed is detected, and the detected information is transmitted to the controller C.

  As an installation example of these detectors D1 to D6, the feed chain 18 of the threshing unit 5 will be described. As shown in FIG. 9, a sprocket that is installed inside the front and rear ends inside the feed chain 18 and wound around the feed chain 18 is used. The output shaft 18c of the threshing unit electric motor M2 is connected to the input shaft 18a fitted to the drive sprocket 18b provided on the rear end side (vehicle rear side) of the feed chain 18, and this output shaft 18c (input) A detector D2 such as a rotary encoder is attached around the axis of the shaft 18a.

  In this way, the detectors D1 to D6 are attached to the drive shafts of the drive units in the traveling unit 3 and the working unit 61. Although not shown, the detector can also be installed on the drive shaft of the handling cylinder 6 driven by engine power. In this case, the detector installed on the handling cylinder 6 is connected to the controller C and the engine E is connected to the controller. A configuration in which the output of the engine E is controlled by the controller C can be added.

  These detectors D1 to D6 (D1, D2, D3a, D3b, D3c, D3d, D4a, D4b, D5, D6a, D6b) are connected to the controller C installed in the vehicle and connected to the controller C. Are connected to inverters I1 to I6 (I1, I2, I3a, I3b, I3c, I3d, I4a, I4b, I5, I6a, I6b) and a driver (not shown).

  Here, when the working conditions of the field are changed, for example, the amount of cereal clusters increases, but when there is a lot of mud on the ground and a rough road, the electric combine 1 reaps a large amount of cereals. The reaping portion electric motor M1 is loaded to increase the working efficiency of the culm pulling device 65, the culm transporting device 67, and the like, and a large amount of the culm is harvested one after another. To the feed chain 18 of the threshing unit 5.

  On the other hand, in the electric combine 1, the vehicle is difficult to travel due to mud in the field, and a load is applied to the traveling unit electric motors M <b> 6 a and M <b> 6 b of the traveling unit 3 so that the vehicle speed decreases. In this case, the rotation speed of the handling cylinder 6 is constant.

  At this time, the detector D1 installed in the cutting unit electric motor M1 detects the rotational speed of the cutting unit electric motor M1 and transmits it to the controller C, and the detector D6 installed in the traveling unit electric motors M6a and M6b The rotational speeds of the traveling unit electric motors M6a and M6b are detected and transmitted to the controller C.

  Therefore, as shown in FIG. 10, when the rotational speeds of the traveling unit electric motors M6a and M6b are reduced in step s1, the controller C proceeds to step s2 and confirms the rotational speed of the reaping unit electric motor M1. When the rotational speed of the reaping portion electric motor M1 is low (the reaping portion 7 is not reaping much cereal), the inverter I2 of the threshing portion electric motor M2 that drives the feed chain 18 is electrically driven. It controls according to the rotational speed of the motor M1, and reduces the rotational speed of the threshing part electric motor M2.

However, the controller C controls the inverter I2 to control the threshing unit electric power when the rotational speed of the reaping unit electric motor M1 has not decreased in step s2 (the reaping unit 7 is reaping a lot of cereals). controlled in accordance with the rotational speed of the reaper electric motor M1 and the rotation speed of the motor M2, causes maintain the rotational speed of the threshing section the electric motor M 2 (or increased).

  With such a configuration, even if a large amount of cereals harvested by the reaping unit 7 is inherited by the feed chain 18 of the threshing unit 5 even though the vehicle speed of the traveling unit 3 is reduced, the controller C can The rotational speed of the threshing unit electric motor M2 is coordinated with the rotational speed of the reaping unit electric motor M1 without reducing the conveying speed of 18.

  As a result, by increasing the conveying speed of the feed chain 18 or setting it to a normal speed, the feed chain 18 is not clogged with the feed chain 18 and the front and rear drive devices including the feed chain 18 are stopped. The cedar can be efficiently conveyed by 18 and the threshing process can be performed by the handling cylinder 6.

  Contrary to the above, when the vehicle comes out of mud or the like and moves to a field with a small amount of grain pods and raises the vehicle speed, the controller C controls the travel unit electric motors M6a and M6b. Even if the rotational speed is increased, the reduction in the amount of cereal reaping reduces the rotational speed of the threshing section electric motor M2 in cooperation with the decrease in the rotational speed of the chopping section electric motor M1, thereby suppressing unnecessary power consumption. Can do.

  In the above-described method for controlling the drive speed of the drive unit, the configuration in which each drive unit is controlled by one controller C has been described. However, the present invention is not limited to this configuration, and a plurality of controllers may be used.

  In this case, as shown in FIG. 11, the controllers C1 to C6 are connected to the detectors D1 to D6 (D1, D2, D3a, D3b, D3c, D3d, D4a, D4b, D5, D6a, D6b), respectively. At the same time, the controllers C1 to C6 are connected to the overall control unit C7. Further, the overall control unit C7 is connected to each of the inverters I1 to I6 (I1, I2, I3a, I3b, I3c, I3d, I4a, I4b, I5, I6a, I6b).

  With such a configuration, each controller C1 to C6 collects detection information of the driving speed of each driving unit by each detector D1 to D6, and the overall control unit C7 is obtained by each controller C1 to C6. Based on the information, the information is analyzed and the inverters I1 to I6 are controlled.

  As a result, each of the controllers C1 to C6 can accurately collect the driving state of each driving system, and the overall control unit C7 can divide the work into information analysis and control instructions to the inverters I1 to I6. The workload of one controller can be reduced and each drive unit can be stably driven and controlled.

  In the above description, cooperative driving between the traveling unit 3 and the reaping unit 7 and the threshing unit 5 of the working unit 61 has been described. However, in the electric combine 1 according to the present invention, the waste processing unit 11, the sorting unit 19, the transport unit 16, and the like. Can be driven in a coordinated manner by all the drive units, including each, and each drive unit is quickly changed to an appropriate drive speed in coordination with the drive speeds of the preceding and following processing steps due to changes in work conditions. In addition, it is possible to prevent clogging of a processed product in the apparatus caused by a difference in driving speed among the driving units and perform processing efficiently.

  As described above in detail, the electric combine 1 of this example includes the engine E (prime mover) and the battery B mounted on the vehicle, and the battery B supplies power to the electric motors M1 to M6 (actuators) via the inverters I1 to I6. The driving unit 3 of the vehicle and the working unit 61 composed of a plurality of processing units are driven by the drive sources of the engine E and the electric motors M1 to M6, and the traveling unit 3 uses the power of the electric motor M3. The working unit 61 includes an actuator driving unit 63 that is driven by the power of the electric motors M1 to M5, and an engine driving unit 62 (primary motor driving unit) that is driven by the power of the engine E. Each drive source of the actuator drive unit 63 is provided with detectors D1 to D6 for detecting the respective drive speeds, and each detector D1 to D1. Connect the 6 to the controller C, and controller C based on the detection information of each detector D1 to D6, and performs control of the inverter I1~I6 connected to the corresponding electric motor M1-M6.

  The present invention can be applied to any electric combiner that uses a prime mover such as an engine and an electric motor as a drive source for continuously harvesting and threshing cereal grains in a field.
