The travelling part is driven with the power of the electric motor. The working part includes an actuator drive part to be driven with the power of the electric motor, and a motor drive part to be driven with the power of the motor.

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 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. The present invention also relates to an electric combiner that includes an engine drive unit that is driven by the power of the engine, and further includes an actuator provided in a traveling wheel that constitutes the crawler traveling device.

  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).

  Furthermore, each of the electric motors for driving the traveling device, the reaping device and the threshing device is provided, and when the traveling load increases and the torque of the traveling electric motor is insufficient, each of the continuously variable transmissions of the threshing electric motor is By engaging and disengaging the transmission clutch via the gear meshing interlock, the threshing electric motor is interlocked with the traveling electric motor, so that the marginal output of the threshing electric motor is used to assist the lack of torque in the traveling electric motor. There is also what (patent document 3) does.

JP 2005-095057 A JP 2007-1111012 A JP 2003-000035 A

  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.

  Moreover, although this patent document 1 also discloses that the driving source of the traveling unit is an electric motor and the driving of the traveling unit and the cutting unit is coordinated, for example, the field changes to a situation where many grains are clustered. In such a case, in order to harvest these large amounts of cereals, 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, although an electric motor is installed independently in a traveling apparatus, a reaping apparatus, and a threshing apparatus, and each apparatus is driven by these electric motors, the left and right traveling electric motors are used in the left and right traveling gears. Since the drive shafts of the left and right traveling drive wheels are linked and coupled to the left and right traveling electric motors, the arrangement of the apparatus is complicated and the traveling electric motor is separately provided in a narrow vehicle space. In addition to the need for a motor installation space, there was a problem that the assembly workability of the vehicle was poor.

  Therefore, an object of the present invention is a battery for supplying electric power to an actuator. The engine and the actuator are used in combination as a vehicle drive source, and only the drive source of the handling cylinder is used as engine power to obtain an optimum power distribution. In addition, the present invention provides an electric combine that improves the work efficiency and reduces the environmental load by efficiently installing an actuator that drives the traveling unit.

An actuator driving unit to be driven and an engine driving unit to be driven by the power of the engine are provided, and the actuator is provided in a traveling wheel constituting the crawler traveling device.

  According to a second aspect of the present invention, in the electric combine according to the first aspect, the traveling wheels are drive sprockets.

  According to a third aspect of the present invention, in the electric combine according to the first aspect, the wiring that connects the actuator that drives the traveling unit and the battery is installed along the side surface of the body frame that supports the vehicle. It is characterized by that.

  According to a fourth aspect of the present invention, in the electric combine according to the first aspect, the wiring is inserted into the body frame through an insertion hole provided in the body frame.

  According to the first aspect of the present invention, the motor and the battery are mounted on the vehicle, and the battery supplies electric power to the actuator via the inverter and includes the crawler type traveling device by each driving source of the motor and the actuator.

In addition, when the vehicle is manufactured, the drive sprockets 3a and 3b including the traveling unit electric motors M6a and M6b can be assembled at a time, and the arrangement configuration of the apparatus is simplified, and the maintainability can be improved. Therefore, it is possible to provide an electric combiner that reduces costs, improves workability, and reduces environmental burden.

Therefore, it is possible to provide an electric combiner with improved power transmission efficiency.

At this time, threshing is performed by rotation of the barrel 6 so that grains, sawdust and the like leak from the receiving net 33.

  Next, the selection unit 19 will be described. The sorting unit 19 performs swing sorting by the swing sorting device 41 and wind sorting by the Kara 42, and is sorted into the first thing, the second thing, the sawdust, and the like.

  The swing sorting device 41 is housed in the machine casing 43. A front end portion of the swing sorting device 41 extends to a position below the front end portion of the handling cylinder 6, and a swing shaft (not shown) is provided at the front lower portion of the swing sorting device 41, and a swing described later is provided at the rear portion. A drive mechanism 44 is provided, and the swing drive mechanism 44 is configured to swing the swing sorting device 41 with respect to the machine frame 43. A fuel tank (not shown) is disposed below the swing drive mechanism 44.

  At the front portion of the swing sorting device 41, a drifting grain plate 45 is provided, and a conveying plate 46 is provided below and below the drifting grain plate 45. These cereal plates 45 and conveying plates 46 are formed by corrugating plate-like members, and the processed material (mixture with grains and swarf etc.) that has passed through the receiving net 33 is the cereal plate 45 and It falls onto the transport plate 46 and is transported to the rear of the machine body by the swing of the swing sorting device 41.

  A net-like grain sieve (sieving device) 47, which is a second sorting unit, is connected to the rear of the transport plate 46, and above the grain sheave 47 and the transport plate 46 and behind the cereal plate 45. A chaff sheave 48, which is a first sorting unit, is mounted. Further, a stroller 49 is disposed behind the chaff sheave 48.

  The chaff sheave 48 is composed of a plurality of chaff fins, and can adjust the opening degree of the chaff fins according to the amount of the processed material to be input. That is, the upper and lower end portions of the chaff fin are pivotally supported by the swing sorting device 41 and are pivotally connected to swing plates provided on the left and right sides of the chaff sheave 48, and the other end portions are provided on the left and right sides of the chaff sheave 48. It is pivotally connected to a sliding plate (not shown) provided.

  The sliding plate is swung integrally with the swing sorting device 41, and an adjusting lever (not shown) is pivotally connected to the sliding plate, and the loosening of a wire (not shown) connected to the adjusting lever is relaxed. Alternatively, the sliding plate is slid back and forth by traction. The adjustment lever is urged in a direction to make the inclination angle of each chaff fin small (lay down) by a spring (not shown) provided on the opposite side of the wire.

  Then, the angle of the chaff fin is changed by sliding of the sliding plate, and when the inclination angle of the chaff fin is made large (standing), the amount of leakage of the grains is increased by increasing the opening of the chaff sheave 48, When the inclination angle of the chaff fin is made small (sleeps), the opening of the chaff sheave 48 is made small so that the amount of grain leakage is reduced.

  Thus, the grains and fine swarf fall down through the chaff sheave 48, and swarf and the like larger than the opening of the chaff sheave 48 are conveyed backward. At this time, an air flow from the front to the rear of the sorting unit 19 is generated between the chaff sheave 48 and the grain sheave 47 by the tang koji 42, and a part of the fine swarf is blown back and separated from the grains. The

  In addition, a red pepper 42 is disposed below the front part of the front grain board 45 and below the front part of the rear grain board 46 in the swing sorting device 19 so as to blow the sorting air to the chaff sheave 48 and the grain sheave 47.

The air is sucked by the fan 50 and discharged out of the apparatus.

  In the process in which the mixture of grains, shoots adhering grains, immature grains and fine swarf that have been thrown into the sorting unit 19 and leaked onto the front-flow grain board 45 is leaked onto the chaff sheave 48, Due to the air flow from the front to the rear of the sorting unit 19 generated by the tang 42, a part of the fine sawdust is blown away backward.

  Then, the mixture of grains, shoots adhering grains, immature grains and fine shavings that have leaked onto the chaff sheave 48 is conveyed rearward by the swinging of the swing sorting device 41. At this time, these grains Grains, immature grains, shoots adhering grains, fine swarf, etc. fall below the opening of the chaff sheave 48, and large swarf is transported to the rear of the chaff sheave 48 and is discharged out of the machine through the stroller 49. The

  In addition, the grains, the immature grains, the shoots adhering grains, the fine shavings, and the like that have dropped below the opening of the chaff sheave 48 are leaked onto the backflow grain plate 46 and the grain sieve 47. At this time, a part of the fine swarf is blown away and separated by the sorting air from the tang 42.

  Further, among the grains, immature grains, shoot adhering grains, and fine swarf leaked on the grain sieve 47, the grain, immature grain, fine swarf, etc. pass through the grain sieve 47 and move downward. Fall. At this time, the heaviest grain (first) is collected by the first collecting unit 51 and is conveyed from the first conveyor 51a, which will be described later, to the grain tank 12 through a cereal conveyor (not shown).

  On the other hand, unprocessed grains mixed with immature grains with a small weight, a part of fine swarf, spiked grains, grains, etc. are blown rearward by the sorting wind from the Karatsu 42 and collected in the second collecting section 52. Then, the second conveyor 52a, which will be described later, passes through a second reduction conveyor (not shown), and is re-introduced onto the upstream cereal board 45 (or the chaff sheave 48).

  As shown in FIG. 6, the power transmission from the engine E and the electric motors M1 to M6 to the drive systems is as follows. First, in the engine drive unit 62, the power of the engine E is the threshing clutch c and the transmission gear. G is transmitted to the drive shaft 6a of the handling cylinder 6 by the V-belt v via g or the like, and the handling cylinder 6 is driven by the power of the engine E.

  On the other hand, since the motive power of the engine E also drives the generator D, the electric power generated by the generator D is charged in the battery B connected to the inverters I1 to I6 described later.

  In the cutting unit 7, for example, the output shaft of the cutting unit electric motor M1 connected to the inverter I1 is coupled to the cutting input shaft 7a that drives the entire cutting unit 7.

For example, the input shaft that drives each device in the cutting unit 7 You may install an electric motor via an inverter, respectively.

  Further, the input shaft 18a that drives the feed chain 18 of the threshing unit 5 is coupled to the threshing unit electric motor M2 connected to the inverter I2, and the swing drive mechanism 44 of the swing sorting device 41 in the sorting unit 19 and The input shafts for driving the Kara 42, the first conveyor 51a linked to the cereal conveyor, the second conveyor 52a linked to the second reduction conveyor, etc. are connected to the inverters I3a, I3b, I3c and I3d constituting the inverter I3, respectively.
