The outside air introduction cover 17 is provided with an intake port 170 for introducing outside air into the intercooler on the upper side and a dustproof net 171 for introducing outside air into the radiator on the lower side.

The combine 1 having the above-described configuration, in packaging, raises and lowers the feeder 40 centered on the harvesting input shaft 47 (support axis) to raise the harvesting unit 4 to a desired height with respect to the ground. (the cutting height of the grain stem, which is a harvested crop), changes from a non-working state to a working state, and travels by the traveling body 3 in that state. As a result, the combine 1 separates the harvested crops into harvesting and non-harvesting objects by means of the left and right separating elements 43 and 43, and separates the harvested crops at the end of the ear of the grain stem that is to be harvested by the raking reel 44. While raking, the narrow portion of the grain stem is cut using the cutting blade device 42.

The narrow portion of the grain stem harvested at the desired harvesting position is raked into the grain header 41 by the rotationally driven raking auger 46, and the feeder house 45 in the left and right central portions of the grain header 41 It is collected near the inlet, passes through the inside of the feeder house 45 by the conveyor inside the feeder house 45, is fed into the feeding port 5a by the front rotor 5b, and is supplied to the threshing section 5.

The narrow portion of the grain stem supplied to the threshing unit 5 is subjected to threshing processing by the threshing unit 5. Specifically, the grain stem supplied to the threshing unit 5 is mainly threshed between the barrel 50 and the water net 51 while being conveyed toward the rear by the rotating barrel 50. Threshing grains such as grains smaller than the mesh of the water net 51 are dropped from the water net 51. The straw scraps and the like that do not leak from the water net 51 are discharged to the packaging through the discharge port formed at the rear of the sorting section 6 by the conveying action of the barrel 50.

On the other hand, the grains that are threshed in the threshing unit 5 and dropped from the water net 51 are subjected to a sorting process by the sorting unit 6. Specifically, the threshed grain that has been threshed in the barrel 50 and dropped from the water net 51 is subjected to sizing, etc. by the specific gravity sorting action by the oscillating sorting plate 60 and the wind sorting action by the tuyere 63. It is sorted and extracted into grains (No. 1 water), mixtures of grains such as grains with attached stems and straw (No. 2 water), and straw scraps.

The grains (No. 1 water) that fell from the oscillating sorting board 60 due to the sorting in the sorting unit 6 are transferred to the grain tank 7 by the No. 1 conveyor 61 and the grain conveyor 64 formed in connection with this. ) is returned to . The No. 2 water is returned to the threshing start end side of the barrel 50 by the No. 2 conveyor 62 and the reduction conveyor formed in connection with it, and is subjected to threshing treatment again. Straw scraps and the like are discharged into the packaging through a discharge port formed at the rear of the sorting unit 6.

The base of the vertical feed auger 8 is rotatably fitted into the vertical portion 741 of the lower support portion 74 from the inside. In short, the vertical feed auger 8 arranges the base (lower part) of the vertical auger pipe 80 with its cylindrical axis coaxial with the vertical part 741 of the lower support part 74, and is located at the bottom of the grain tank 7. It is disposed at a position rearward of the rear side wall 702, and is supported from below so as to be able to pivot around the vertical portion 741 of the lower support portion 74.

The lower support portion 74 has a pair of bevel gears (not shown) supported on bearings inside the L-shaped corner portion. One bevel gear is formed at the rear end of the rotation axis of the screw conveyor as the discharge conveyor 72, and the other bevel gear is formed at the lower end of the rotation axis of the screw conveyor of the vertical feed auger 8, and are meshed with each other. That is, the rotational power of the screw conveyor of the discharge conveyor 72 is transmitted as the rotational power of the screw conveyor of the vertical transfer auger 8 through a pair of bevel gears, and is accompanied by the rotational drive of the screw conveyor of the discharge conveyor 72. Thus, the screw conveyor of the vertical transfer auger (8) is driven to rotate.

Moreover, as shown in FIGS. 4-7, the vertical feed auger 8 has an intermediate part supported by the upper support part 75 formed in the upper part of the rear side wall 702 of the grain tank 7. The upper support part 75, together with the lower support part 74, is a part that rotatably supports the vertical auger pipe 80 of the vertical feed auger 8 from the inside. The upper support portion 75 is formed in a substantially Ω shape when viewed in plan, is fixed to the rear wall 702 at both ends, and protrudes rearward from the rear wall 702.

In detail, as shown in FIGS. 6 and 7, the upper support portion 75 includes an auger bracket 750 connected to and fixed to the rear wall 702, and an auger bracket 750 connected to the auger bracket 750. It has an auger holder 751 that supports the middle portion of the vertical auger pipe 80 of the vertical feed auger 8 from the outer peripheral side.

The auger bracket 750 is composed of a metal strip member formed in a substantially M-shape when viewed from the top. As shown in FIG. 6, the auger bracket 750 is formed by bending the center of the M-shaped image into an arc and forming a front auger holder portion 750a corresponding to the front outer peripheral portion of the vertical feed auger 8, and at both ends of the M-shaped image. It has fixing parts 750b and 750b fixed to the rear wall 702. The fixing portions 750b and 750b of the auger bracket 750 are fixed to the rear left vertical frame 730 and the rear right vertical frame 731 of the skeletal frame 73 by fastening fastening members such as bolts, The front auger holder portion 750a protrudes rearward from the rear wall 702.

The auger holder 751 is composed of a metal strip member formed in a substantially U-shape when viewed from the top. The auger holder 751 is connected to the left and right sides of the auger bracket 750 at both ends of the U-shape and a rear auger holder portion 751a corresponding to the rear outer peripheral portion of the vertical auger pipe 80 of the vertical feed auger 8. It is provided with fixing parts (751b, 751b).

The fixing portions 751b and 751b of the auger holder 751 are fixed to the auger bracket 750 by fastening fastening members such as bolts while abutting the left and right outer sides of the auger bracket 750. The rear auger holder portion 751a of the auger bracket 750 can be rotated by inserting the vertical auger pipe 80 of the vertical transfer auger 8 together with the front auger holder portion 750a of the auger bracket 750. When viewed from the supporting plane, an approximately circular vertical feed auger insertion hole is formed. In this way, the vertical feed auger 8 is supported by maintaining the standing posture by the lower support part 74 and the upper support part 75 at the rear position of the grain tank 7.

Moreover, the upper support part 75 is provided with the drive part 76 which rotates the vertical feed auger 8. The drive unit 76 is formed by an electric motor 760 connected to a motor base 761 that is mounted and fixed to the rear end of the auger holder 751. The electric motor 760 has a drive shaft 760a protruding downward, and is connected to and held by the motor base 761 to the upper support portion 75.

As shown in FIGS. 6 and 7 , a drive-side pinion gear 760b is formed on the protruding portion of the drive shaft 760a. On the other hand, a pinion gear 82 on the driven side that meshes with the pinion gear 760b on the drive side is formed on the outer periphery of the central portion of the vertical auger pipe 80 of the vertical feed auger 8. The pinion gear 82 is a gear ring formed of a plurality of gears, and is fitted and fixed to the middle part of the vertical auger pipe 80 from the outside.

Discharge is carried out by a pinion mechanism formed by the driving part 76 disposed on the upper support part 75 in this way, the pinion gear 760b of the electric motor 760, and the pinion gear 82 of the vertical feed auger 8. The auger 9 performs the following turning operation with the vertical feed auger 8 as the central axis of turning.

When the pinion gear 760b is driven to rotate integrally with the rotation of the drive shaft 760a of the electric motor 760, the pinion gear 82 on the driven side and the vertical auger pipe 80 integrated with the lower support portion 74 ) is driven to pivot around the vertical portion 741. In short, the vertical feed auger 8 maintains an upright posture on the traveling body 3, engages the pinion gear 760b of the electric motor 760 with the pinion gear 82, and drives the electric motor 760. By this, it rotates relative to the left and right directions about the barrel axis. Accompanying this, as shown in FIG. 3, the discharge auger 9 formed to connect to the upper part of the vertical feed auger 8 rotates in the left and right directions around the vertical feed auger 8. In this way, the left and right positions of the discharge auger 9 are adjusted by displacing the discharge auger 9 in the left and right directions as a whole around the base.

In addition, as shown in FIGS. 8 and 9, the discharge auger 9 has a lifting mechanism and a lever mechanism, and the base is pivoted on a pivot support shaft 81 protruding from one side of the upper part of the vertical feed auger 8. It is supported and configured to move up and down in the upper part of the vertical feed auger 8.

A grain communication port (not shown) communicating with the discharge auger 9 is formed on the outer peripheral side of the upper part of the vertical auger pipe 80 of the vertical feed auger 8. On the outer peripheral side of the base of the horizontal auger pipe 90 of the discharge auger 9, a single-circular communication pipe 91 is formed to protrude orthogonal to the cylindrical axis direction of the horizontal auger pipe 90.

The discharge auger (9) loosely fits the communication pipe (91) into the communication port of the vertical auger pipe (80) of the vertical transfer auger (8), and the center of the communication port and the tubular axis of the communication pipe (91) are coaxially aligned. It is connected rotatably through the arranged pivot support shaft 81. The pivot support shaft 81 protrudes from the upper part of the vertical auger pipe 80 to one side opposite to the communication port.

A pair of bevel gears (not shown) supported by bearings are formed on the inside of the communication pipe 91, which is a connection portion between the upper part of the vertical feed auger 8 and the base of the discharge auger 9. One bevel gear is formed at the upper end of the rotation axis of the screw conveyor of the vertical feed auger 8, and the other bevel gear is formed at the base end of the rotation shaft of the screw of the discharge auger 9, and are meshed with each other.

That is, the rotational power of the screw conveyor of the vertical transfer auger 8 is transmitted as the rotational power of the screw conveyor of the discharge auger 9 by the bevel gear, and the discharge is accompanied by the rotational drive of the screw conveyor of the vertical transfer auger 8. The screw conveyor of the auger (9) is driven to rotate.

In addition, between the upper part of the vertical feed auger 8 and the base of the discharge auger 9, as shown in FIGS. 8 and 9, discharge is centered on the pivot support shaft 81 from the upper part of the vertical feed auger 8. A lifting mechanism and a lever mechanism for rotating the auger 9 up and down are provided.

The lifting mechanism consists of a lifting cylinder 92 that is formed on the upper part of the vertical auger pipe 80 of the vertical feed auger 8 and expands and retracts. The lever mechanism is connected to the lifting cylinder 92 and the base end of the horizontal auger pipe 90 of the discharge auger 9, and consists of a lever frame 93 that rotates up and down about the pivot support shaft 81. .

As shown in FIGS. 8 and 9, the lifting cylinder 92 as a lifting mechanism includes a cylinder tube 920 and a piston rod 921 that expands and contracts within the cylinder tube 920. The lifting cylinder 92 has a first rotation axis ( 920a) is pivotably supported so as to be able to rotate up and down.

The first bracket 83 is a fixing member with a square shape in cross section that is fixed to the upper part of the vertical auger pipe 80 and protrudes to one side. The first bracket 83 has a ring-shaped normal mounting portion 830 that is inserted and fixed from the outside to the vertical auger pipe 80 of the vertical conveying auger 8 at the base end, and a tangential outward direction from the mounting portion 830. It has a connection part 831 that protrudes from the top, and a square-shaped support part 832 that supports the lifting cylinder 92 at the tip of the connection part 831.

The first bracket 83 orients the square-shaped open portion of the support portion 832 at the tip of the connection portion 831 in the horizontal or vertical direction, and is attached to the mounting portion 830 at the base end of the connection portion 831 to form a vertical auger pipe. It is mounted on the upper outer circumference of (80). The first bracket 83 arranges the central portion of the cylinder tube 920 of the lifting cylinder 92 between the upper and lower horizontal sides of the square shape of the support portion 832 that opposes each other in a vertical plane, and has a first rotation axis ( 920a), the lifting cylinder 92 is pivotably supported so that it can rotate up and down.

The lever frame 93 includes a strip-shaped lever plate 930 whose both ends are mounted so as to be vertically movable by rotating around the pivot support shaft 81, and a second bracket formed on one end of the lever plate 930 ( 94) and is formed on the other end of the lever plate 930 and the first connection arm 931 connected to the lifting cylinder 92 through the end of the horizontal auger pipe 90 of the discharge auger 9 (proximal cover body ( It has a second connection arm 932 connected to 90b)). Additionally, the base end cover 90b projects a fixing convex portion 900b that fixes the end of the second connection arm 932.

The lever plate 930 has a bearing portion at approximately the center of the plate surface in the longitudinal direction, and is pivotably supported on the pivot support shaft 81 by the bearing portion.

The first connection arm 931 has one end connected to and fixed to the lever plate 930 and protrudes from the plate surface of the lever plate 930, and a second bracket 94 is fixed to the other end.

The second connection arm 932 is distracted from the upper rear of the vertical feed auger 8 and between the lever plate 930 and the proximal end cover body 90b on the proximal end side of the horizontal auger pipe 90, and is provided at both ends. It is connected to and fixed to the lever plate 930 and the discharge auger 9.

The second bracket 94 is a fixing member having a pair of side wall portions 940, 940 arranged in plane parallel at regular intervals. The second bracket 94 is fixed to one end of each side wall portion 940, 940 by penetrating the first connection arm 931. The second bracket 94 arranges the piston rod 921 of the lifting cylinder 92 on the other end and between the side wall portions 940 and 940, and pivotably supports the piston rod 921 so as to rotatably. The second rotation axis (921a) is being celebrated.

In other words, the piston rod 921 is pivotably supported on the second bracket 94 so that it can rotate up and down about the second rotation axis 921a. In short, the lifting cylinder 92 rotates the cylinder tube 920 on the proximal end in the vertical direction about the first rotation axis 920a at the connection portion between the vertical feed auger 8 and the discharge auger 9. In addition to being pivotably supported so as to be capable of displacement, the piston rod 921 on the distal end side is pivotably supported to be capable of being rotationally displaced in the up and down directions about the second rotational axis 921a.

In this way, the lifting cylinder 92 as a lifting mechanism and the lever frame 93 as a lever mechanism formed between the upper part of the vertical feeding auger 8 and the base of the discharge auger 9 have the vertical feeding auger 8 as the center. It follows the discharge auger (9) and turns integrally, and the longitudinal movement of the discharge auger (9) is performed as follows.

When the discharge auger 9 is operated in a rolling motion at the upper part of the vertical transfer auger 8, the lifting cylinder 92 is retracted and operated as shown in FIG. 10(a). That is, in the contracted form of the lifting cylinder 92, the distance between the first bracket 83 on the fixed side and the second bracket 94 on the operating side becomes short, so that the lever moves around the pivot support shaft 81. The first connection arm 931 is pressed down at one end of the plate 930 by the second bracket 94, and the second connection arm 932 is raised at the other end of the lever plate 930.

In short, as the first connection arm 931 is lowered, the lever plate 930 rotates and displaces the pivot support shaft 81 to the support point, thereby raising the second connection arm 932. By raising the second connection arm 932, the base end of the transverse auger pipe 90 of the discharge auger 9 (base end cover body 90b) is raised using the pivot support shaft 81 as a pivot support point, The tip of the horizontal auger pipe 90 of the discharge auger 9 is lowered. As a result, the posture of the discharge auger 9 is rotated and displaced as a whole to the prone posture. At this time, the lifting cylinder 92 is tilted around the lower first rotation axis 920a and the upper second rotation axis 921a to enter a standing posture.

When the discharge auger 9 is operated to stand at the upper part of the vertical feed auger 8, the lifting cylinder 92 is operated to distract, as shown in FIG. 10(b). In the distracted form of the lifting cylinder 92, the distance between the first bracket 83 and the second bracket 94 becomes longer, so that the first bracket 83 is positioned at one end of the lever plate 930 with the pivot support shaft 81 as the center. 2 The first connection arm 931 is pushed up by the bracket 94, and the second connection arm 932 is lowered from the other end of the lever plate 930.

In short, as the first connection arm 931 rises, the lever plate 930 rotates and displaces the pivot support shaft 81 to the support point, causing the second connection arm 932 to fall. By lowering the second connection arm 932, the base end (base cover body 90b) of the horizontal auger pipe 90 of the discharge auger 9 is lowered, using the pivot support shaft 81 as a pivot support point, The tip of the transverse auger pipe 90 of the discharge auger 9 rises. As a result, the attitude of the discharge auger 9 is rotated and displaced as a whole to an inclined attitude. At this time, the lifting cylinder 92 tilts around the lower first rotation axis 920a and the upper second rotation axis 921a to enter an inclined posture.

In this way, the discharge auger 9 is placed in a stowed state stored in the auger rest 95 or the rice inlet 9a is placed on the outside of the traveling body 3 by jointly performing the lifting operation and the above-described turning operation. It should be used by placing it on the truck bed, etc. That is, the discharge auger 9 includes a lifting cylinder 92 as a lifting mechanism, a lever plate 930 as a lever mechanism, a first connecting arm 931, a second connecting arm 932, etc., and is a vertical feed auger. The lifting and lowering mechanism and the lever mechanism rotate and operate as a center.

In order to avoid the discharge auger 9, the lifting cylinder 92, and the lever frame 93 colliding with the grain tank 7 during the turning operation of the discharge auger 9, A concave portion 77 is formed. The recessed part 77 of the grain tank 7 is formed in the upper rear end of the grain tank 7. That is, the concave portion 77 follows the turning trajectory of the discharge auger 9 centered on the vertical feed auger 8 and the turning trajectory (swinging path) of the lifting cylinder 92 and the lever frame 93 in the grain tank. This is the clearance part formed in (7).

As shown in FIGS. 5 and 6, the recessed portion 77 of the present embodiment is a grain tank formed by the rear wall 702, the left wall 703, the right wall 704, and the upper wall 705. By making the rear upper corner of the grain tank 7 into a rectangular shape and cut across the entire width direction when viewed from the side of the grain tank 7, the outer shape of the grain tank 7 is made into a front convex shape and a rear concave shape. , It is formed as a flat rear end part 770 in the rear end upper part of the grain tank 7.

The upper wall 705 includes a first flat portion 705a that is mostly flat on the front side, and a first inclined wall portion 705b that slopes gently backward and downward from the first flat portion 705a, It has a second inclined wall portion 705c that is steeply inclined backward and downward from the first inclined wall portion 705b, and a second flat portion 705d that is flat backward and horizontally from the second inclined wall portion 705c, When viewed from the side, the anterior convex shape also forms a posterior concave shape.

In addition, the left wall 703 and the right wall 704 have upper edges connected to both edges of the upper wall 705, respectively, and have a front convex shape following the shape seen from the side of both edges of the upper wall 705. It has a concave shape at the rear. The second flat portion 705d is supported by the left rear vertical frame 730 and the right rear vertical frame 731, and forms a horizontal flat surface of the rear end 770 as the concave portion 77.

The left wall 703, right wall 704, and upper wall 705 are fixed to the skeletal frame 73 as described above. In particular, the left rear vertical frame 730 and the right rear vertical frame 731, which support the upper side wall 705 and the rear wall 702, are the second flat portion of the upper side wall 705, as shown in FIG. 705d is supported from the lower side to form a rear end 770. Thereby, the discharge auger 9, the lifting cylinder 92, and the lever frame 93 can be made to swing smoothly without using the grain tank 7 as a barrier.

The rear dewatering portion 370 is formed on the rear edge of the loop portion 310 excluding the outlet portion 380 of the harness 101 of the remote monitoring terminal 100, which will be described later. As a result, water that accumulates on the upper surface 310b of the loop part 310 of the support member 300 and tries to enter the inside of the lower surface 310a along the front and rear edges is removed, and the connection part 120 of the remote monitoring terminal 100 is removed. ) can be prevented from getting wet with water.

In addition, the front dewatering unit 360 and the rear dewatering unit 370 are each bent from the front and rear edges of the loop unit 310 to the inside of the support member 300 at a predetermined angle, thereby forming the upper surface of the loop unit 310. The surface continuous to (310b) may be formed as a tapered surface.

The outlet portion 380 of the harness 101 is an opening portion formed in the rear corner of the support member 300. The outlet portion 380 is formed by cutting the rear end of the left support portion 320.

In addition, the remote monitoring terminal 100 has a first harness portion 101a supported by the support member 300 together with the remote monitoring terminal 100, as shown in FIGS. 16 to 18(a). In short, the harness 101 connecting the remote monitoring terminal 100 and the control device A16 includes at least a first harness portion 101a connected to the remote monitoring terminal 100 side and a first harness portion 101a connected to the control device A16 side. It has a second harness portion 101b connected to it. The first harness portion 101a and the second harness portion 101b are connected via a terminal side coupler 103 and a control side coupler 104 that are formed at each other's ends and fit between a male and female.

As shown in FIG. 16 , the support member 300 has a coupler fixing portion 390 for fixing the terminal coupler 103 formed in the middle portion of the harness 101 at a predetermined position on the lower surface 310a. The coupler fixing portion 390 is formed near the outlet portion 380 of the harness 101 at the rear and left portion (rear left corner portion) of the lower surface 310a of the loop portion 310.

Additionally, the connection surface of the terminal side coupler 103 with the control side coupler 104 is disposed inside the outlet portion 380.

As a result, the connection parts such as the first harness part 101a and the terminal side coupler 103, which are connected to the remote monitoring terminal 100 installed on the combine 1 through the support member 300, are not exposed to water without being exposed to the outside. It can prevent it from getting wet. In addition, the operation of connecting the control side coupler 104 of the second harness portion 101b to the connection surface of the terminal side coupler 103 disposed inside the outlet portion 380 of the harness 101 can be easily performed. can do.

In this way, the remote monitoring terminal 100 and the antenna 200 are integrally mounted on the common support member 300 and unitized to form the antenna unit 400. As a result, maintenance work for the remote monitoring terminal 100 and the antenna 200 is completed at one point, so not only maintainability is improved, but wiring of the harness can be simplified. In particular, since the antenna harness 201 that connects the remote monitoring terminal 100 and the antenna 200 is supported on the support member 300 together with the remote monitoring terminal 100 and the antenna 200 and unitized. , the wiring of the antenna harness 201 can be eliminated.

That is, the work of fixing the placement of the remote monitoring terminal 100 to the combine 1, the work of fixing the placement of the antenna 200, and the harness 101 and harness 201 of the remote monitoring terminal 100 and the antenna 200, respectively. ) The remote monitoring terminal 100 and the antenna 200 are connected to each other simply by placing and fixing the support member 300 at a predetermined position of the combine 1, eliminating the need for layout work on individual members, such as wiring arrangement work. It can be integrated and placed nearby to improve work efficiency.

[5. Layout configuration of remote monitoring terminal and antenna for combine]

Next, the layout configuration of the remote monitoring terminal and antenna for the combine will be described in detail. As described above, as the antenna unit 400, the remote monitoring terminal 100 and the antenna 200 unitized by the support member 300 are located nearby and disposed on various members constituting the combine 1. If so, there is no limitation on the layout configuration. The remote monitoring terminal 100 and the antenna 200 of this embodiment are positioned in the vicinity of each other on the same plane outside the grain tank 7, and are set as a layout structure formed. Moreover, in this embodiment, the combine 1 on which the antenna unit 400 is mounted may be of the so-called self-destruction type.

The support member 300 of the antenna unit 400 is located at the rear end 770 as a concave portion 77 formed in the upper rear end which is the rear of the grain tank 7, and is a skeletal frame of the grain tank 7. (73) It is integrally connected and fixed to.

In this embodiment, the same plane outside the grain tank 7 in which the remote monitoring terminal 100 and the antenna 200 are formed becomes the 2nd plane part 705d. In detail, as shown in FIGS. 6 and 8 , the support member 300 is disposed at the central portion in the width direction of the second flat portion 705d forming the upper surface of the rear end portion 770 in the width direction. In addition, the support member 300 has the front opening 300a and the rear opening 300b facing the front and rear openings 300b, as shown in FIGS. 6 and 7 in the front-back direction. The opening surface is arranged to be substantially flat on the rear wall 702 of the grain tank 7. In addition, the arrangement formation position of the rear end 770 of the support member 300 is generally within the surface of the concave portion 77 (within the front-to-back width of the second flat portion 705d) when the support member 300 is viewed in plan. and within the left and right widths). As a result, the remote monitoring terminal 100 and the antenna 200 supported by the support member 300 are placed in the concave portion 77.

At the position of the concave part 77 of the grain tank 7, the support member 300 attaches the left fixing part 340 and the right fixing part 350 to the left rear vertical frame 730 and the right rear vertical frame, respectively. It is in contact with the frame 731 and is fixed by fastening members 340b and 350b. In short, the support member 300 is connected to the left horizontal part 730a of the left rear vertical frame 730 and the right rear vertical frame, respectively, by the left fixing part 340 and the right fixing part 350 of the left and right flange parts. It is formed integrally with the right horizontal portion 731a of the central portion, the loop portion 310 of the central portion, the left support portion 320, the right support portion 330, and the mounting surface (of the second flat portion 705d). upper surface), the remote monitoring terminal 100 forms a vertical dome-shaped space.

In this way, since the support member 300 is firmly fixed integrally with the mounting surface to the skeletal frame, the remote monitoring terminal 100 operates the engine 10, the threshing unit 5, and the combine 1. It is possible to prevent sudden displacement or separation due to the influence of vibration of various devices such as unit (6).

In particular, the remote monitoring terminal 100 and the antenna 200 are attached to the left support portion 320 so as to float from the mounting surface of various devices such as the upper wall 705 of the grain tank 7 in the support member 300. and the right support part 330, so that even if there is vibration of various devices, the vibration is not directly transmitted to the remote monitoring terminal 100 or the antenna 200.

The support member 300 transmits vibrations of various devices from the left fixing part 340 and the right fixing part 350, the left support part 320 and the right support part 330, and the left support part 320 and the right support part 330. In the process of transmitting it to the loop portion 310, each part is bent and deformed, and ultimately the vibration transmitted to the remote monitoring terminal 100 or the antenna 200 is attenuated.

In other words, the support member 300 directly receives and attenuates vibrations from various devices to prevent problems occurring in the remote monitoring terminal 100 or the antenna 200. In addition, even if a problem occurs with the remote monitoring terminal 100 or the antenna 200, the layout configuration is arranged at the upper rear end of the grain tank 7 through the support member 300, so access by maintenance workers is easy. This further improves maintainability.

In addition, the support member 300 supports the rear portion 116, which forms the connection portion 120 and the connection ramp 130 of the remote monitoring terminal 100 supported on the lower surface 310a, as shown in FIGS. 19(a) and FIG. As shown in 19(b), it is formed in the predetermined position of the grain tank 7 which can be visually recognized from the rear of the combine 1. In this embodiment, the support member 300 is arrange|positioned in the grain tank 7 with the rear part 116 facing rearward with respect to the front-back direction of the traveling body 3.

As a result, the operator can perform maintenance work such as mounting the remote monitoring terminal 100 and the antenna 200 to the combine 1, as well as checking whether the mounted remote monitoring terminal 100 and the antenna 200 are operating normally. This becomes simpler.

Moreover, the support member 300 is located in front of the vertical feed auger 8 and is formed in the grain tank 7. Specifically, the support member 300 is disposed in the recessed part 77 of the grain tank 7 by opposing the opening surface of the rear opening 300b to the vertical auger pipe 80.

More specifically, the remote monitoring terminal 100 and the antenna 200 supported by the support member 300 raise and lower the discharge auger 9 from the upper end of the vertical feed auger 8, and the vertical feed auger 8 ) is located below the turning trajectory and lifting trajectory (swinging lifting path) of the lifting cylinder 92 as a lifting mechanism and the lever frame 93 as a lever mechanism that rotates integrally with the discharge auger 9, It is arranged in the recessed part 77 of the grain tank 7.

In other words, the remote monitoring terminal 100 and the antenna 200 have a rotating path formed by the lifting cylinder 92 and the lever frame 93 that rotate together with the discharge auger 9 in the vertical direction and the granular tank ( 7) is disposed between the upper walls 705 with a free space above. The vertical distance between the lower end of the rotating lifting cylinder 92 and the upper side wall 705 of the grain tank 7 is longer than the height formed by the support member 300 and the antenna 200. Additionally, the antenna 200 formed by standing on the upper surface 310b of the support member 300 is disposed outside the turning path of the vertical feed auger 8 and in front of the concave portion 77.

That is, the antenna 200 formed and supported on the upper surface 310b of the support member 300 is raised and lowered in the vertical direction as shown in FIGS. 10(a) and 10(b). At a position below the turning path of the lifting cylinder 92 in the standing posture or inclined posture, and in the front-back direction, at a position outside the turning path of the lifting cylinder 92, the concave portion of the granular tank 7 has a free space ( 77) is placed in .

Therefore, above the remote monitoring terminal 100 and the antenna 200 disposed in the recess 77 of the grain tank 7 through the support member 300, the discharge rotates around the vertical transfer auger 8. The lifting cylinder 92 and lever frame 93, which follow and rotate together with the auger 9 and the discharge auger 9, are operated to rotate smoothly without interfering with the remote monitoring terminal 100 and the antenna 200.

In this way, by arranging the remote monitoring terminal 100 and the antenna 200 through the support member 300 to the grain tank 7, it is integrated with the discharge auger 9 centered on the vertical feed auger 8. The lifting cylinder 92 as a rotating lifting mechanism and the lever frame 93 as a lever mechanism do not collide with the remote monitoring terminal 100 and the antenna 200 supported by the support member 300, and the remote monitoring terminal 100 and problems with the antenna 200 can be prevented.

In addition, as shown in FIG. 20, the antenna unit 400, which is an integrated unit structure in which the remote monitoring terminal 100 and the antenna 200 are supported on the support member 300, is mostly vertical in the left and right directions. It is located within the range of the outer diameter d1 of the auger pipe 80.

In detail, as shown in FIG. 20, the antenna unit 400 has the left and right edge portions of the loop portion 310 of the support member 300, the left support portion 320, and the right support portion ( 330) and the left fixing part 340 and the right fixing part 350 are arranged to be exposed on both left and right sides from the vertical auger pipe 80. Therefore, the remote monitoring terminal 100 mounted on the left and right central portions of the loop portion 310 is positioned entirely within the range of the outer diameter d1 of the vertical auger pipe 80 in the left and right directions. In short, the remote monitoring terminal 100 is arranged so that the entire casing 110 overlaps the vertical auger pipe 80 when viewed from the rear.

In this way, by placing the antenna unit in front of the vertical auger pipe 80 of the vertical feed auger 8, the antenna unit can be placed close to the vertical auger pipe 80, so that the axial center of the vertical auger pipe 80 In a configuration in which the grain tank 7 rotates left and right outward (right side) with the center of rotation, wiring of the harness 101 becomes easy and loosening or tension of the harness 101 can be suppressed. . In addition, the harness 101 can be taken out from the antenna unit 400 to the rear side of the grain tank 7, that is, to the rotational support point side of the discharge auger 9, so that the harness 101 at the rear of the combine 1 Wiring installation work becomes easier.

In addition, the remote monitoring terminal 100, the antenna 200, and the support member 300 that constitute the antenna unit are each located at least in part within the range of the outer diameter d1 of the vertical auger pipe 80 in the left and right directions. It just needs to be formed. In short, each configuration of the remote monitoring terminal 100, the antenna 200, and the support member 300 may be formed so that at least part of the configuration overlaps the vertical auger pipe 80 when viewed from the rear.

In addition, since the remote monitoring terminal 100 and the antenna 200 are unitized by the support member 300, the work of individually arranging and mounting the remote monitoring terminal 100 and the antenna 200 is eliminated. Additionally, the work of installing the harness 101 and harness 201 connected to them is eliminated, and work efficiency is greatly improved.

As explained above, according to the present invention, the remote monitoring terminal and antenna can be concentrated and arranged at a predetermined position of the grain tank of the combine, and the mountability and maintainability of the remote monitoring terminal and antenna can be improved.

In other words, regarding the layout configuration of the remote monitoring terminal and antenna that transmits the location information and operation information of the combine to the management server, the remote monitoring terminal and antenna, which were conventionally distributed separately, are concentrated by a common support member. By supporting it into a unit, the remote monitoring terminal and antenna can be integrated and placed simply by mounting the support member at a predetermined point (one point) of the combine, simplifying the installation work and improving maintainability. There is a possible effect.
