[0018] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0019] As shown in Figures 1 and 2, a general-purpose combine harvester has a traveling device 2 consisting of a pair of left and right crawlers that travels on the soil surface on the underside of a body frame 1, a pre-harvesting processing device 3 that harvests stalks in the field on the front side of the body frame 1, a threshing device 4 that threshers and sorts the harvested stalks on the rear left side of the pre-harvesting processing device 3, and a control unit 5 with a driver's seat 5A where an operator sits on the rear right side of the pre-harvesting processing device 3.

[0020] An engine room 6 housing the engine E is provided below the control unit 5, a grain tank 7 for storing threshed and sorted grain is provided behind the control unit 5, and a discharge auger 8 for discharging the grain to the outside is provided behind the grain tank 7.

[0021] The pre-harvest processing device 3 is composed of a raking device 3A that rakes up the stalks in the field and transports them to the rear while standing upright, a cutting blade device 3B that cuts the base of the stalks that have been erected by the raking device 3A, an auger device 3C that gathers the stalks transported to the rear of the raking device 3A to the left side, and a feeder house 3D that houses a conveying belt that transports the gathered stalks to the threshing device 4.

[0022] An opening spanning the entire width on both sides is formed on the bottom surface of the lower wall 10 of the feeder house 3D where the conveying belt is inverted from top to bottom, and a gravel storage box 20 is attached to cover the opening from below. Gravel and other materials shaken off from the grain straw being transported within the feeder house 3D are stored in the gravel storage box 29. The gravel storage box 29 is located on the left side of the operating unit 5 and closest to the feeder house 3D, making it easy to check the gravel storage box 29.

[0023] A dust discharge box 30 is provided in the approximate midpoint between the front and rear of the top wall 11 of the feeder house 3D. A transparent observation window 13 is provided in the top wall 11 behind the dust discharge box 30, allowing a view into the gravel storage box 20 through the transported grain straw (material to be processed) and the accumulated gravel to be observed. The observation window 13 can also be opened with an openable cover plate to allow a view inside for inspection work.

[0024] As an alternative configuration for the gravel storage box 20, if the right side of the width of the feeder house 3D is extended toward the control section 5, the top surface is made transparent, and the bottom surface is tilted to the right, the gravel will collect on the right side, and as shown in Figure 4, an operator sitting in the control seat 5A of the control section 5 can check the gravel that has accumulated in the gravel storage box 20. Also, as shown in Figure 3, the gravel storage box 20 is configured to be provided in the latter half of the length of the conveying passage of the feeder house 3D.

[0025] A blower fan is provided inside the dust discharge box 30, and the air containing dust and other particles inside the feeder house 3D is discharged to the outside of the machine. That is, as shown in Fig. 3, the air is discharged from a discharge section 30A formed at the bottom of the dust discharge box 30 on the left side of the feeder house 3D.

[0026] The dust discharge box 30 is provided in the first half of the length of the conveying passage of the feeder house 3D, and the gravel storage box 20 is provided in the second half of the length of the conveying passage of the feeder house 3D. This makes it easier to check the condition inside the gravel storage box 20.

[0027] If multiple slits or narrow openings are provided on the right and left sides of the gravel storage box 20 to allow hot air from the engine E to pass through, even wet gravel can be dried and easily discharged. As shown in Figure 7, in particular, by placing the gravel storage box 20 in the path of the cooling air from the engine E or by providing a guide 32 to guide the cooling air from the engine E, it becomes easier to take in the air, further promoting the drying action of the gravel.

[0028] Furthermore, if a transparent window is provided on the left side of the gravel storage box 20, an operator standing on the left side of the machine frame 1 can check the state of the gravel inside.

[0029] In the case of a specification that does not include a gravel storage box 20, the lower wall 10 of the feeder house 3D is covered with a blocking plate 33, but as shown in Figure 8, the blocking plate 33 may also be used as the bottom plate of the gravel storage box 20.

[0030] As shown in Figure 5, a gravel storage box 20 may be provided in front of the entrance of the threshing device 4 in a section where the distance between the conveying chain 31 of the feeder house 3D and the bottom surface of the lower wall 10 inside the feeder house 3D gradually increases (angle K). This allows the conveying slats attached to the conveying chain 31 to move away from the bottom surface of the lower wall 10, improving the stone recovery rate.

[0031] When a gravel storage box 20 is installed near the end of the conveying path of the feeder house 3D, such as in front of the entrance to the threshing device 4, in a combine harvester in which the feeder house 3D is configured to be able to drive in reverse, even if the material to be processed becomes clogged in front of the entrance to the threshing device 4, the gravel and other materials can be collected in the gravel storage box 20 over a short distance, allowing the blockage to be cleared and work to be resumed quickly.

[0032] As shown in Figure 6, the gravel storage box 20 may be configured to be able to be pulled out to the left, thereby facilitating the stone removal work.

[0033] A reaping lifting cylinder 17 is provided to raise and lower the pre-reaping treatment device 3, and a lock bar 15 that extends the reaping lifting cylinder 17 to keep the pre-reaping treatment device 3 elevated is attached to the bottom of the feeder house 3D by a pivot shaft 15A and also serves to prevent the gravel storage box 20 from falling. When not in use, the lock bar 15 is fixed along the bottom of the feeder house 3D by a lock bar fixing pin 18 to prevent the gravel storage box 20 from accidentally falling.

[0034] The gravel storage box 20 can be pivoted on either the left or right side and opened downwards or slid left or right to remove, but if it is opened using an opening / closing lever 19 provided facing the control unit 5, an operator at the control unit 5 can open the gravel storage box 20 and release gravel onto the crawler traveling device 2 without damaging the machine body. By providing the opening / closing lever 19 between the control unit 5 and the feeder house 3D, operation becomes easier. [Explanation of symbols]
