Description

  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 driving unit is driven by the power of the actuator, and the working unit is driven by the power of the actuator. An actuator drive unit that is driven by the motive power of the actuator, and the actuator drive unit includes a mowing unit, and constitutes the mowing unit. The vertical conveying device for conveying the straw is provided with an actuator for driving these devices, and the upper conveying device relates to an electric combiner provided with a posture adjusting means for adjusting the conveying posture of the harvested cereal.

  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 addition, a vertical conveying device that sandwiches and conveys the culm stock side to deliver the cereal harvested by the reaping part to the feed chain of the threshing part at the rear of the cereal merging point at the end of the conveying chain in the reaping part In addition, an upper transport device that sandwiches and transports the tip of the grain pod is vertically installed following the vertical transport device, and an actuator that rotates the vertical transport chain is provided in the vertical transport device. There is one that adjusts the handling depth of the cereal by the handling cylinder by rotating the stock conveying side vertical conveying chain by rotation to move the tip conveying position (for example, Patent Document 3).

  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. There was a problem that let me. Furthermore, since the traveling part is driven by the power of the engine, a large number of power transmission members such as gears and shafts are required, which complicates the configuration.

  In addition, this Patent Document 1 also discloses that the driving source of the traveling unit is an electric motor to coordinate the driving of the traveling unit and the reaping unit. For example, the farm is difficult to travel on the vehicle, but there are many grains. When the conditions change to clustering, a large amount of cereal is harvested, and as a result, a load is applied to the electric motor that drives the harvesting unit. 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.

  Furthermore, in a combine like patent document 3, when conveying a grain straw to a feed chain, in order to adjust the handling depth, only the vertical conveyance apparatus which conveys the stock side of a grain straw is rotated, and the tip is conveyed. Since the position has moved, after transporting the cereals whose transport posture is greatly inclined after the merging point of the harvested cereals, the tip of the posture cannot be reliably processed by the handle cylinder only by the rotation of this vertical transport device. In some cases, the feed chain is transported as it is, and there is a problem in that the cereal is left unhandled.

  Accordingly, an object of the present invention is to achieve optimal power distribution by using a prime mover (engine) and an actuator that obtains electric power from a battery as a vehicle drive source, and using only the drive source of the barrel as engine power. At the same time, the present invention provides an electric combine with reduced environmental load.

Yes.

  Further, the transport means 10 includes an upper transport device 77 including a transport chain that holds the tip of the cereal cocoon transported by the above-described upper transport tine 75 and the lower transport chain 76 and inherits it to the feed chain 18; And a vertical conveying device 78 composed of a conveying chain that is passed to the feed chain 18 by sandwiching it. Although not shown in FIGS. 5 to 6, each driving device described above is provided with a motor (not shown) connected to the battery B via an inverter (not shown). The motor is driven by the generated electric power. In addition, since the arrangement | positioning position of these motors can be designed suitably, detailed description and illustration are abbreviate | omitted in this application.

Also, as is well known as shown in FIG. 8, on the upstream side base of the vertical transport device 78, attached threshing depth motor 78 M, rear (downstream side) it is rotatably supported on the pivot axis A detector (not shown) that detects the stock side and the tip side of the cereal is disposed on the transport path of the transport means 10 to detect the cereal and transmit a signal to the controller C described later. , by controlling the normal and reverse rotation of the threshing depth motor 78 M, the transfer terminal end portion of the vertical transport device 78, rotates the fulcrum shaft as a rotation fulcrum, the threshing portion 5 regardless of the length of culms It is configured to keep the handling depth of the supplied cereal at an appropriate level.

  The above-described upper transport device 77 is provided with posture adjusting means S that adjusts the posture of the transported culm that is the main part of the present invention. This is because the motor M7 connected to the battery B via an inverter I7, which will be described later, is installed in the upper transport device 77 at an appropriate position such as a frame, and the inverter I7 is installed in the vicinity of the upper transport device 77. A posture adjusting tool 79 such as a dial (not shown) for adjusting the driving speed of the motor M7 is connected via the inverter I7.

  Therefore, as shown in FIG. 9, the posture adjustment means S can be composed of a motor M7, an inverter I7, an adjustment tool 79, and the like. Although not shown in FIGS. 5 to 6 described above, the upper transport device 77 is normally driven by the motor M7 with the power of the battery B, and the vertical transport device 78 is also driven by the motor (not shown) with the power of the battery B. .

Here, the cereals harvested by the cutting blade 9 are transported by the transport means 10 to the junction m , and then the tip of the threshing section 5 is sandwiched between the upper transport device 77 and the stock root by the vertical transport device 78, respectively. When transported toward the feed chain 18, for example, as shown in FIG. 10, it is transported due to the length and amount of the culm, the harvested state, or the transport speed difference between the upper transport device 77 and the vertical transport device 78. There is a case where the conveyance is continued in a posture in which the tip is greatly inclined in the forward direction (rearward direction) of the stock direction.

In this case, the operator, in the upper transport device 77, in a state where the tip is large inclined and which (strain base side toward the rear in the conveying direction preceded the feed chain 18 side than the tip side of the conveying culms in THRESHER In the case of a shallow handling position or a state where threshing is not possible), the posture adjustment tool 79 is operated to increase the drive speed of the motor M7 via the inverter I7.

  That is, since the conveying speed of the upper conveying device 77 is increased, the conveying speed on the tip side is higher than the conveying speed on the stock source side in the vertical conveying device 78, and the conveyed cereal is delivered to the feed chain 18. In this case, the cereal can be adjusted to a posture in the vicinity of a substantially right angle with respect to the conveying direction. As a result, it can be set as the attitude | position which can carry out the threshing process reliably by the handling cylinder 6. FIG.

State also contrary to the above, the operator, in the upper transport device 77, which largely inclined is (tip side toward the front of the tip is the conveying direction of the conveying culms preceded the feed chain 18 side than strain base side In the case where the handling cylinder is in a shallow handling position or cannot be threshed), the posture adjusting tool 79 is operated to lower the driving speed of the motor M7 via the inverter I7.

  That is, since the conveying speed of the upper conveying device 77 is lowered, the conveying speed on the tip side is lower than the conveying speed on the stock side in the vertical conveying device 78, and the conveyed cereal is delivered to the feed chain 18. In this case, the cereal can be adjusted to a posture in the vicinity of a substantially right angle with respect to the conveying direction. As a result, it can be set as the attitude | position which can carry out the threshing process reliably by the handling cylinder 6. FIG.

By setting it as such a structure, the conveyance cereal can be adjusted to the conveyance attitude | position which made the tip surely threshing-processable with the handling cylinder 6, and threshing efficiency can be raised. Especially in the present application, even when the vertical transport device 78 is rotated by the threshing depth motor 78 M to adjust the threshing depth of culms, when the culms is not conveyed to the appropriate posture, posture adjusting means described above S Can increase the threshing efficiency.

The posture adjusting means S can be automatically controlled. FIG. 11 is a control block diagram of the posture adjusting means S ′ having a detector. In this case, as shown in FIG. 8, for example, a detector 80 such as a CCD camera (not limited) is installed in a frame in the vicinity of the upper conveyance device 77. The detector 80 is connected to the controller C, and a motor M7 is connected to the controller C via an inverter I7.

  Therefore, as shown in FIG. 11, the posture adjusting means S ′ includes a detector 80, a controller C, an inverter I7, and a motor M7. It should be noted that the controller C is inputted with a changeable setting range (target value) of the conveying posture with respect to the conveying posture (conveying angle) of the culm detected by the detector 80 in the upper conveying device 77.

  And as mentioned above, the tip side of the carrying cereal being conveyed by the upper conveying device 77 and the vertical conveying device 78 is greatly inclined beyond the set range in the front-rear direction of the conveying direction with respect to the stock source side. Based on the information detected by the detector 80, the controller C controls the motor M7 through an inverter so that the transport speed of the upper transport device 77 according to the difference between the inclination of the cereal and the target value is obtained. Control drive speed. As a result, as described above, the cereals that are being transported through the upper transport device 77 can be adjusted to a posture in the vicinity of a substantially right angle with respect to the transport direction.

  With such a configuration, the transporting cereal can be automatically adjusted to a transporting posture in which the tip is surely threshing-processed by the handling cylinder 6, and the worker can easily increase the threshing efficiency.
