The grain box 4 is higher than the threshing part 3, and the height of the grain box 4 is higher than that of the threshing part 3.

The harvesting and conveying section 2 includes: a plurality of holding devices 7 for holding the fallen vertical grain stalks; a pusher-type harvesting knife 8 as a harvesting part for cutting the root of the uprighted grain stalk; and a grain stalk carrying device 9 for slowly changing the longitudinal grain stalks cut at the roots by the harvesting knife into a horizontal tilting posture and carrying the grain stalks toward the threshing part 3 positioned at the rear side of the machine body; and the like.

The threshing section 3 performs threshing treatment of the top side of the ear of the grain stalks inside while holding the roots of the grain stalks by the supply chain 10 and carrying them backward. The grains obtained by threshing are stored in a grain tank 4.

There is also a grain discharging device 11 for discharging the grains stored in the grain tank 4 to the outside. The bottom part of the grain box 4 has a bottom screw 12, and the bottom screw 12 transfers the stored grains to the rear and outside and conveys the grains to the grain discharging device 11. The grain discharging device 11 includes: a vertical conveying part 13 for conveying upward the grains discharged from the lower rear part of the grain box 4 through the bottom screw 12; and a horizontal conveying part 14 for conveying the grains from the upper part of the vertical conveying part 13 along the horizontal direction. The horizontal conveying section 14 has a discharge port 15 for discharging grains at a distal end thereof. The vertical conveying section 13 and the horizontal conveying section 14 are each constituted by a spiral conveyor.

The driver unit 1 includes: a driver seat 16 on which a driver sits; and various operation members for operation by the driver.

The combine harvester has a position information acquiring device 17 that acquires position information of the machine body. The position information of the body includes information indicating a route along which the body travels. The position information acquiring device 17 is a well-known technique, and therefore, the detailed description thereof will be omitted, and the position of the body is detected by a Global Navigation Satellite System (GNSS) (for example, GPS (global positioning system), GLONASS (global navigation satellite system), Galileo (Galileo satellite navigation system), beidou satellite navigation system, or the like) that acquires position information of the vehicle by receiving radio waves from a plurality of satellites.

The position information acquiring device 17 includes: a transmitting/receiving unit 18 capable of transmitting/receiving information relating to the body position to/from an external device; and a device body portion 19. The transmission/reception unit 18 receives radio waves related to position information transmitted from a plurality of satellites, not shown, as an example of an external device. The device main body 19 performs calculation processing for calculating the position of the body from the received radio waves. The transmitter/receiver 18 transmits only the positional information of the body obtained by the device main body 19 to an external management device as an example of an external device.

The transceiver 18 is provided at the upper part of the grain tank 4. Specifically, as shown in fig. 3, the transceiver 18 is provided on the upper surface 4a of the rear upper part of the grain box 4. The receiving and dispatching unit 18 is provided at a position lower than the lower end of the horizontal conveying unit 14 of the grain discharging device 11. The grain tank 4 is made of an iron plate made of a metal material, and the transmission/reception unit 18 is provided with a mounting unit having a magnet. The transmitter/receiver 18 is attached to the grain tank 4 in a state of being attracted by a magnet.

The transceiver 18 is placed on an iron support stand 20 of the grain tank 4. The transmission/reception unit 18 is attracted to the support base 20 by the magnetic force of the magnet.

As shown in fig. 1, 2 and 4, the device main body 19 is provided between the rear surface portion 4b of the grain tank 4 and the vertical conveying portion 13 in a state of overlapping the vertical conveying portion 13 when viewed from the rear surface. A cover 21 is provided to surround the device main body 19. The device body 19 is bolted to the rear surface 4b of the grain tank 4. The cover 21 is provided to cover the rear of the device main body 19, and both left and right sides are fixed to the rear surface 4b of the grain tank 4.

The device main body 19 and the transmission/reception unit 18 are connected by a wire harness 22. The length of the wire harness 22 is set to a length that allows the transmitter/receiver unit 18 to be attached to the upper surface 4a and the side surface 4c of the grain tank 4. Therefore, as shown in fig. 3, the transmitter/receiver 18 can be attached to the right side surface 4c of the grain tank 4 while the transmitter/receiver 18 is attached to the upper surface 4a of the grain tank 4 and the transmitter/receiver 18 is removed against the magnetic force.

(5) In the above embodiment, the transmission/reception unit 18 acquires the positional information of the body and transmits only the positional information to the external device, but instead of this configuration, it may transmit not only the positional information of the body but also various information included in the positional information, for example, having a timekeeping function, managing the positional information in a state corresponding to the date and time, and transmitting composite information to which the change in the positional information caused with the passage of time is added.

(6) In the above embodiment, the device main body 19 is provided between the rear surface portion of the grain tank 4 and the vertical conveying portion 13 in a state of overlapping the vertical conveying portion 13 when viewed from the rear surface, but instead of this configuration, the device main body 19 may be provided on the lateral side surface of the grain tank 4, or the device main body 19 may be provided on the upper surface portion 4a of the grain tank 4. In order to make it difficult to access the device main body 19 and to make it difficult for an operator to touch it, the device main body 19 may be preferably provided on a lateral side of the grain box 4 on the threshing part 3 side, or the like.

(7) In the above embodiment, the grain box 4 is provided as the grain storage unit, but instead of this configuration, a storage hopper may be provided as the grain storage unit.

(other means for solving the problems)

In the above embodiment, the transmitter/receiver 18 may be mounted on the upper part of the grain storage unit (grain box 4), and the following solutions may be provided as solutions to the problems of the present invention.

Although not shown, a support column is provided which is erected on the machine body frame 6 and extends upward at least to a position higher than the threshing section, preferably to a position higher than the grain tank 4, and in this configuration, the transmission/reception section 18 may be attached to the support column at a position higher than the grain tank 4 in a fixed state.

Even with the above configuration, the transmission/reception unit 18 is provided at a high position, and therefore, there is little obstacle when transmitting/receiving information and little vibration when traveling during work, and therefore, information can be transmitted/received appropriately. Also, there is less possibility of collision with an external object and damage. As a result, the position information acquisition means can be set in an appropriate state.

(availability in industry)

The invention can be applied to semi-feeding type combine harvesters and common combine harvesters.
