Description

  The present invention relates to a combine provided with a preprocessing unit and a threshing unit having a handling cylinder for threshing cereals harvested by the preprocessing unit, and more particularly to a display unit on which an operating state of the handling cylinder is displayed.

  In general, a general-purpose combine, which is a type of combine, has its handling cylinder rotated by an engine as a power source to thresh the cereal. The rotation speed of the barrel should be changed according to the crop to be threshed. For example, when threshing easily damaged beans, etc., it is necessary to rotate the handling cylinder at a low speed, and when threshing wheat or rice that is difficult to thresh, the handling cylinder needs to be rotated at a high speed. For this reason, a general-purpose combine that can change the rotation speed of the barrel has been proposed (see Patent Document 1).

JP 2013-81377 A

  However, in the general-purpose combine described in Patent Document 1, since the operator can select the rotation speed of the handling cylinder, there is a possibility that the handling cylinder may be rotated at a speed that is not suitable for crops to be cut and threshed by mistake. For this reason, there is a problem that troubles occur in the mowing and threshing work. For example, if the operator mistakenly rotates the handling cylinder at low speed for beans and threshing rice, the handling cylinder is less capable of threshing, and a large amount of processed material that does not finish threshing is provided with the handling cylinder. Stay in the treatment room. As a result, there is a problem that the handling room is clogged with the processed material, and the mowing and threshing operation is interrupted.

  Therefore, an object of the present invention is to provide a combine that improves the visibility of the operator with respect to information that informs the rotation speed of the handling cylinder and solves the above-described problems.

The present invention relates to a threshing comprising a driving operation part (10) having a driver's seat (31), a pretreatment part (5), and a handling cylinder (47) for threshing the cereals harvested by the pretreatment part (5). In the combine (1) comprising the part (6),

  According to the first aspect of the present invention, the information for notifying the rotation speed of the handling cylinder is displayed on the display unit arranged in front of the driver's seat in the driving operation unit, so that the rotation speed of the handling cylinder is notified. The visibility of the operator with respect to information is improved. For this reason, even when the combine is traveling, the operator can easily check the rotation speed of the cylinder, and can easily notice the error when the wrong speed is set.

  According to the second aspect of the present invention, since the information is displayed by at least one of a color and a symbol that change according to the rotation speed of the handling cylinder, a space for displaying the information on the display unit is reduced. Is done. For this reason, the space for displaying information other than the information which alert | reports the rotation speed of a handling cylinder on a display part expands.

The processed material subjected to specific gravity sorting is subjected to leakage sorting by a chaff sheave 26. The chaff sheave 26 has a plurality of plate-shaped fins 30 extending in the left-right direction, and these fins 30 are arranged side by side in the front-rear direction. Contaminants in the processed product are blown away backward by the sorting air of the Kara fan 21 arranged in front of and under the chaff sheave 26. On the other hand, the grain in the processed material falls through a gap between the fins 30 and falls to a grain sheave 29 disposed below the chaff sheave 26. These fins 30 are supported so as to be rotatable in the front-rear direction. As the fin 30 rotates, the opening degree of the fin 30 is changed, and the accuracy and speed of the sorting by the chaff sheave 26 change. What has fallen from the chaff sheave 26 and deposited on the glensieve 29 is further finely selected by the glensieve 29. The grain selected by the grain sieve 29 falls on the first spiral 22 and is conveyed to the grain tank 11. What remains in the selection of the grain sieve 29 falls to the second spiral 23 and is returned to the threshing unit 6. The Strollac 27 drops the grains mixed in the impurities remaining in the leakage selection of the chaff sheave 26 onto the second spiral 23. The waste disposal unit 9 is disposed behind the stroller 27 and includes a suction device for sucking out impurities remaining in the stroller 27.

  As shown in FIG. 3, the driving operation unit 10 is provided with a driver seat 31 on which a driver sits. A main transmission lever 32 and a sub-transmission lever 33 are arranged on the left front side of the driver seat 31 from the side close to the driver seat 31. The operator operates the auxiliary transmission lever 33 to switch the traveling speed of the general-purpose combiner 1 to a fast speed for traveling on the road or a slow speed for cutting and threshing. Further, the main speed change lever 32 performs fine speed adjustment and forward / backward switching of the traveling direction of the general purpose combine 1. A sorting adjustment dial 35 for changing the opening degree of the fin 30 is disposed behind the main transmission lever 32 and the auxiliary transmission lever 33, that is, to the left of the driver seat 31 in the driving operation unit 10. The sorting adjustment dial 35 also serves as a sorting automatic switch. Depending on the traveling speed and the layer thickness of the processed object detected by the layer thickness sensor 67 (see FIG. 2) for detecting the layer thickness of the processed object deposited on the chaff sheave 26 when the operator presses the sorting adjustment dial 35. The automatic sorting adjustment control for automatically adjusting the opening degree of the fin 30 is activated or stopped. An inter panel 37 provided with a steering lever 36 for performing a turning operation of the general purpose combine 1 is arranged in front of the driver's seat 31. The steering lever 36 is provided on the right side of the inter panel 37. On the left side of the inter panel 37, an operation panel 39 for adjusting the cutting and threshing work is arranged.

The reel rotation adjustment dial 40 also serves as a reel rotation automatic switch. When the operator presses the reel rotation adjustment dial 40, the automatic reel rotation adjustment control that automatically adjusts the rotation speed of the scraping reel 19 in accordance with the traveling speed is activated or stopped. When the operator operates the cutting height adjustment dial 41, the cutting height position control that restricts the lifting / lowering operation of the preprocessing unit 5 with respect to the traveling machine body 3 is adjusted. A cutting clutch 43 (see FIG. 4) for connecting and disconnecting the path is provided in the middle of a path for transmitting power from the engine E (see FIG. 4), which is a power source, to the preprocessing unit 5. Is detected by a cutting clutch detection sensor 45 (see FIG. 5). When the connection of the cutting clutch 43 is detected by the cutting clutch detection sensor 45, the cutting height position control is activated. When the cutting height position control is activated, the ascending / descending operation of the preprocessing unit 5 is limited so that the height of the preprocessing unit 5 with respect to the traveling machine body 3 does not fall below a lower limit value. The lower limit value is set by the operator operating the cutting height adjustment dial 41. When the ground cutting height automatic switch 42 is turned ON, when the connection of the cutting clutch 43 is detected by the cutting clutch detection sensor 45, the height of the preprocessing unit 5 with respect to the field scene is automatically set. Therefore, the ground cutting height control that is kept constant is activated in preference to the cutting height position control. In the ground cutting height control, the target height of the pre-processing unit 5 with respect to the farm scene can be changed by the cutting height adjustment dial 41, similarly to the lower limit value of the cutting height position control.

  Here, the threshing unit 6 will be described with reference to FIG. The threshing unit 6 has a handling chamber 46 into which the cereals that have been conveyed from the conveying feeder 13 are placed, and a cylindrical handling cylinder 47 extending in the front-rear direction is rotatably supported inside the handling chamber 46.

A helical handle 49 extending in the front-rear direction is formed on the outer peripheral surface of the handle cylinder 47 extending in the front-rear direction, and the cereals conveyed from the pretreatment unit 5 are handled in the front end of the handle cylinder 47. A spiral-shaped spiral blade 50 is formed in order to rake into the back of 46. A receiving net 51 formed in an arc shape when viewed from the front is disposed along the outer peripheral surface of the handling cylinder 47 below the handling cylinder 47. By rotating the handling cylinder 47, the tooth handling 49 handles the grain from the cereal and threshes. The processed product in which the threshed grains and impurities are mixed is sieved by the receiving net 51.

  A gear case 52 to which power from the engine E is transmitted is disposed on the right side of the rear portion of the handling chamber 46. As shown in FIG. 4, a shaft 53 that transmits power from the engine E to the gear case 52 and a shaft 55 that outputs power from the gear case 52 are connected to the gear case 52. A pulley 61 is fixed to the shaft 55 protruding from the gear case 52. A pulley 62 is fixed to the rear end of the handling cylinder 47, and a belt 63 is wound around the pulley 62 and the pulley 61. Power from the engine E is transmitted to the handling cylinder 47 via the shaft 53, the inside of the gear case 52, the shaft 55, the pulley 61, the belt 63 and the pulley 62. Inside the gear case 52, gears 56 and 57 supported by the shaft 53 and gears 59 and 60 supported by the shaft 55 are provided. The gear 56 can mesh with the gear 59, and the gear 57 can mesh with the gear 60. However, the gear 56 and the gear 59 are engaged, and the gear 57 and the gear 60 are not engaged. Only one of the gears 56 and 59 or the gears 57 and 60 meshes. The power of the shaft 53 is transmitted to the shaft 55 via the gears 56 and 59 when the gear 56 is engaged with the gear 59, and the shaft 55 is transmitted via the gears 57 and 60 when the gear 57 is engaged with the gear 60. Is transmitted to. The gear 56 has a diameter larger than that of the gear 57, and the gear 60 has a diameter larger than that of the gear 59. Therefore, the rotational speed of the handling cylinder 47 in the high speed state in which the gear 56 meshes with the gear 59 is higher than the rotational speed of the handling cylinder 47 in the low speed condition in which the gear 57 meshes with the gear 60.

  The rotational speed of the handling cylinder 47 is mounted on the general purpose combine 1 and is detected by a rotor rotation sensor 65 shown in FIG. As shown in FIG. 5, the rotor rotation sensor 65 is connected to a control unit 66 that controls the operation of the general purpose combine 1. The control unit 66 is connected to the above-described selection adjustment dial 35, reel rotation adjustment dial 40, cutting height adjustment dial 41, ground cutting height automatic switch 42, and cutting clutch detection sensor 45 together with the rotor rotation sensor 65.

A cutting height setting value 92 for notifying a lower limit value in height position control is displayed.

  Below the cutting height gauge 90, a rotor speed symbol 93 for notifying the rotational speed of the handling cylinder 47 is displayed. A threshing clutch 95 (see FIG. 4) for connecting and disconnecting the route is provided in the middle of the route for transmitting power from the engine E to the threshing unit 6 and the sorting unit 7. The rotor speed symbol 93 is displayed on the liquid crystal display unit 73 when the threshing clutch 95 is connected. When the rotation speed detected by the rotor rotation sensor 65 is equal to or higher than a predetermined speed, the rotor speed symbol 93 is displayed by characters (symbols) “rotor high speed” written with a black background. The predetermined speed is set between the rotational speed of the handling cylinder 47 in the high speed state and the rotational speed of the handling cylinder 47 in the low speed state. When the rotation speed detected by the rotor rotation sensor 65 is less than a predetermined speed, the rotor speed symbol 93 is displayed by the characters (symbols) “rotor low speed” written with a yellow background.
