Also,
The funnel 11 of the Glen tank 3 has a check lid 1 that can be opened and closed freely.
38 are provided. The inspection cover 138 is slid or rotated to open an opening provided in the funnel 11.

(Operation) Next, the operation based on the above configuration will be described. Sitting on the cockpit 4 and moving the machine forward, weeding the culm with the weeds, cutting the weeded stalk with a reel and cutting with a cutting blade, and supplying the cut culm to the threshing apparatus 2 Threshing and wind selection, the first thing is taken out by the first conveyor, and stored in a grain tank 3 provided on the side of the threshing apparatus 2 by a grain feeding frying apparatus. The discharge unit 12 of the Glen tank 3 is connected to an intermediate portion of a discharge tube member 14 to which a blower 15 for blowing compressed air is connected. Since the outlet 16 is provided with the grain discharging device 13 configured to turn vertically and to move up and down, when the grain is full in the Glen tank 3, the aircraft is caused to travel to the vicinity of the truck that is waiting near the field. The grain outlet 16 is located above the tank of the truck. In this case, since the grain discharge port 16 can be freely moved up and down and swiveled, the positioning with the tank of the truck is facilitated. Further, since the grain discharge port 16 can be freely moved up and down and swivel, it is not necessary to lock the grain discharge port to the tank of the truck, thereby facilitating the discharge operation.

When the blower 15 is operated in this state, the grains in the Glen tank 3 enter the intermediate portion of the discharge tube member 14 from the funnel portion 11 through the discharge portion 12 and are conveyed by the compressed air from the blower 15. The cereal thus discharged is discharged from a cereal discharge port 16 to a tank provided on a truck. In this case, the grains in the Glen tank 3 are discharged from the discharge section 12 to the discharge cylindrical member 14.
The discharge unit 12 is provided with a discharge feeding mechanism 100 that discharges a substantially fixed amount at a lower portion of the funnel unit 11, so that the kernels are discharged from the upper opening 106 of the drum 101 between the rotary blades 103. , And is conveyed to the drop port 104 below the drum 101 by the rotating rotor 103, and falls from the drop port 104. That is, the grains are combined with the air from the blower 15 by the feeder 107 to be described later and conveyed. However, since the grains fall by a fixed amount and merge, the wind pressure applied to each grain becomes substantially constant, and And air conveyance becomes smooth. If the amount of drop is different, the grain is likely to be clogged when the amount is large, and the grain may be skipped and stay in the feeder 107 when the amount is small, but this is prevented. Since the upper part of the feeder 107 is connected to the lower part of the drop port 104 of the drum 101, the kernels dropped from the drop port 104 are sent to the air discharge port 116 by the air blown from the air inlet 114 of the feeder 107. It is skipped, enters the intermediate tube portion 18 from the lower connection tube portion 111, and is conveyed to the grain discharge port 16 by high-pressure air and discharged.

Further, the feeder 107 is formed on the upper inclined surface 113 approaching the lower connecting cylinder 111 as it goes down, and the feeder 107 drops because the air inlet 114 is opened in the upper inclined surface 113. The grain is on the good slope 113
As a result, it is guided to move diagonally to the lower connection cylinder portion 111 side, and in this state, the air is blown from the air inlet 114, so that the grains smoothly move on the transport air. Further, since the air inlet 114 is opened obliquely on the upper inclined surface 113, a time difference occurs between the upper and lower portions of the air inlet 114 when the wind hits the kernel, so that the merging becomes smooth. In other words, when air is blown from just beside the grains falling almost vertically, the wind pressure tends to strongly act only on the grains falling to the side close to the air inlet 114. At the upper part of 114, it is easy to hit a near grain, and at the lower part, it is easy to apply a conveying wind to the grain that is farther from the air inlet 114, and the grain is discharged while being diffused, so that the occurrence of clogging is reduced. Thus, the feeder 107 forms a recess 115 by passing the lower edge of the air inflow port 114 and inclining downward to the lower connection cylinder 111 side following the upper slope 113 and forming the recess 115.
15 is formed on an inclined surface which becomes higher as it approaches the lower connection tube 111 from its intermediate portion, and the upper inner surface on the lower connection tube 111 side is inclined toward the lower connection tube 111 as it goes down. Since the grain is formed on the lower side inclined surface 117, the grain that has joined the conveying air is guided toward the air discharge port 116 by the concave portion 115 and the lower side inclined surface 117, and the inside of the lower side connection cylinder portion 111 is formed. to go into.

Since the discharge motor 108 is configured to be changeable in rotation by a variable speed motor such as an inverter motor, the rotation of the feeder 1 is changed by changing the rotation.
The amount of fall to 07 can be changed, and it is efficiently discharged in an optimal state depending on the type and properties of the grain. That is, if the rotation speed of the rotary blade 103 is simply increased, but exceeds a predetermined rotation speed, the substantial opening time of the inflow chamber 105 is shortened, and a sufficient amount of grains are rotated before falling, so that Since the amount of inflow is rather reduced, the number of revolutions of the rotary blade 103 is changed depending on the type and properties of the grain, thereby improving the drop efficiency while preventing clogging. The upper opening 10
6 is provided with a falling amount adjuster 120 capable of adjusting the opening area of the upper opening 106 to be large or small.
By adjusting not only the number of rotations but also the opening area of the upper opening 106, the grain is more efficiently discharged in an optimum state depending on the type and properties of the grain. Since the transmission on / off clutch 68 of the blower 15 and the discharge / delivery mechanism 100 (discharge motor 108) are turned on at substantially the same timing, the kernel from the blower 15 in a state where the blowing from the blower 15 is delayed is delayed. Can be prevented from dropping and clogging. When the transmission on / off clutch 68 is in the off state, the discharge / delivery mechanism 100 (discharge motor 10
8) is not operated (the discharging motor 108 is not energized), so that the grain is prevented from being clogged by an erroneous operation in the initial operation.

That is, in the embodiment, when the operation driving unit 123 of the transmission on / off clutch 68 is operated, the control unit 124 detects this fact, and the control unit 124 sets a predetermined time lag when the transmission on / off clutch 68 is turned on. The motor switch 122 of the discharge motor 108 is turned on. Therefore, the grains are dropped in a state where the air is flowing so that the blower 15 is operated and the grains can be sufficiently conveyed into the feeder 107 of the discharge unit 12, so that the clogging is prevented.
Stopping of the discharge motor 108 is optional, but if the blower 15 continues blowing for a predetermined time even after the discharge motor 108 is stopped, it is possible to prevent the grains in the discharge tube member 14 from being clogged. Is preferred. In this case, the discharging and feeding mechanism 1
00, the grain in the feeder 107 is moved to the grain outlet 1
It is preferable to stop after a time required to completely discharge the paper from the nozzle 6 because clogging can be more reliably prevented. Although the material of the discharge cylinder member 14 is arbitrary, at least the base of the supporting horizontal frame 33 of the vertical discharge cylinder 19 and the horizontal discharge cylinder 20 projecting from the upper end opening of the vertical rotation cylinder 29. Is formed of a deformable flexible member, so that the vertical discharge cylinder 1
When the horizontal discharge cylinder 20 is turned with respect to 9, it is deformed,
The grain can be turned without clogging, facilitating alignment.

In the present embodiment, when the body is driven near the truck, the vertical drive cylinder 29 is rotated by the turning drive source 30 with respect to the lower metal 28 so that the horizontal discharge cylinder 20 is centered on the vertical rotary cylinder 29. By turning, the grain discharge port 16 of the horizontal discharge cylinder section 20 is positioned above the tank of the truck, and the blower 15 is operated in this state, and the grains in the Glen tank 3 pass through the discharge section 12 from the funnel section 11 through the discharge section 12. The vertical discharge cylinder portion 1 in the vertical rotation cylinder 29 enters the intermediate cylinder portion 18 of the discharge cylinder member 14 and passes through the intermediate cylinder portion 18 by compressed air from the blower 15.
9 into the horizontal discharge cylinder 20 and the horizontal discharge cylinder 20
And discharged from the grain discharge port 16 to a tank provided on the truck. The supporting horizontal frame 33 is provided so as to be offset so that the mounting member 31 is not overlapped with the opening 22 of the vertical rotating cylinder 29 in a plan view. Since the bent portion 24 is not obstructed by the mounting member 31 and the supporting horizontal frame 33, the bent portion for avoiding them is small, and the bent portion 24 can be arranged substantially linearly from the opening 22 to the supporting horizontal frame 33 in plan view. . Therefore, the grains move smoothly in the discharge tube member 14, and the conveyance is smooth and reliable. Further, since the discharge tubular member 14 is provided along the side surface of the support horizontal frame 33 on the side of the opening 22, the grain discharge port 1 is provided through the opening 22.
6 is substantially linear in a plan view, so that the conveyance is smooth and reliable.

The mounting shaft 23, which is the center of rotation of the mounting member 31, removes (separates) from above the opening 22 in side view.
Since the support horizontal frame 33 is provided at one of the start end and the end in the longitudinal direction, the bent portion 24 between the vertical discharge cylinder 19 and the horizontal discharge cylinder 20 is bent in a side view. The so-called radius of the portion 24 (the radius of the arc-shaped bent portion 24) is increased. Therefore, the grains move smoothly in the discharge tube member 14, and the conveyance is smooth and reliable. Thus, the locking member 35 is formed in a horizontal U-shape, is fixed at a plurality of predetermined intervals, and the horizontal discharge cylinder portion 20 is inserted into each locking member 35. This is preferable because the weight can be reduced as compared with the case where it is inserted into the formed cylinder. Thus, the discharge tube member 14 connects the base side tube portion 17 connected to the blower 15 to the outside of the vertical rotation tube 29 (the anti-threshing device 2).
Side, the cut ground side) toward the discharge unit 12 and the discharge unit 1
2 is formed at a predetermined position past the turning portion 38 toward the vertical rotary cylinder 29, and the base side cylinder portion 17 turned back from the turning portion 38 is connected to the discharge portion 12.
The starting end of the intermediate cylinder portion 18 is connected to the vertical rotation cylinder 29 side of
Since the end of the intermediate cylindrical portion 18 extends toward the vertical rotary cylinder 29, the air from the blower 15 on the vertical rotary cylinder 29 side is sent to the discharge section 12 toward the vertical rotary cylinder 29 by the folded portion 38. Can transport grains.

Therefore, the arrangement is rational, and the length of the base-side cylindrical portion 17 from the blower 15 to the discharge portion 12 of the Glen tank 3 is shortened to reduce the pressure loss of air.
Since the Glen tank 3 is configured to rotate laterally with respect to the fuselage side about the lower longitudinal axis 27 and the upper longitudinal axis 36, the Glen tank 3 is opened and the transmission mechanism is opened. The maintenance work has been facilitated by opening the doors. In this case, the lower vertical axis 27 and the upper vertical axis 3
6 is provided on the side where the blower 15 is provided, and the return portion 38 is located on the rotation end side of the Glen tank 3. Therefore, when the Glen tank 3 is opened, it is necessary to attach / detach the discharge tube member 14. No open work is easier. Then, the base side cylindrical portion 17 connected to the blower 15 on the rear side extends the outside of the vertical rotary cylinder 29 (the side opposite to the threshing device 2 and the cut ground side) toward the discharge portion 12 and is folded from the folded portion 38. , A more rational arrangement, blower 1
5 from the base to the discharge part 12 of the Glen tank 3
7 to reduce the pressure loss of the air. In this case, since the base side tubular portion 17 and the intermediate tubular portion 18 of the discharge tubular member 14 are configured to be stretchable and deformable, when the Glen tank 3 is opened, it does not need to be detached and attached, thereby facilitating the opening operation. It is suitable.

Further, since a part or the whole of the discharge cylinder member 14 is formed of a transparent member whose inside can be viewed,
In addition to facilitating maintenance, it is not only preferable that the horizontal discharge tube portion 20 of the discharge tube member 14 is locked by the locking member 35 along the side of the support horizontal frame 33 and almost exposed. As a result, it can be seen from the cockpit 4 and can respond quickly to clogging. Thus, instead of the feeder 107, the discharge unit 12 is provided at the lower part of the drum 101 of the discharge / feed mechanism 100 with the auxiliary outlet 1
Since the auxiliary take-out portion 126 having the auxiliary take-out portion 25 is detachably mounted, the grains can be discharged from the Glen tank 3 without using the blower 15,
Improve operability and workability. That is, when the grain bag 129 is attached to the auxiliary outlet 125 and the discharge / delivery mechanism 100 is operated, the kernel bag 129 is filled with grains, and the discharging operation is performed. I can do it. Therefore, it is possible to select the discharging operation of discharging the truck to the tank and filling the bag. In this case, since the proximity operation switch 127 for the discharge motor 108 is provided near the auxiliary extraction unit 126 separately from the motor switch 122, the discharge motor 108 is operated by the operation switch proximity operation switch 127. Operable and improve operability. Also,
In the vicinity of the auxiliary outlet 125, an engaging member 128 is provided.
Is provided, the work can be performed by suspending the grain bag 129, and operability and workability are improved.

According to another embodiment of the discharge unit 12 shown in FIG.
Is omitted, and the injection feeder 130 that joins the grains to the high-pressure air from the discharge cylinder member 14 is provided, so that the configuration is simple. In this case, one or both of the throat 131 and the nozzle 132 are detachably attached to the main body 133, so that maintenance is facilitated. In the embodiment of FIG. 23, the throat 1
31 is provided so as to be rotatable about the longitudinal axis 134 with respect to the main body 133, so that not only the maintenance inside the injection feeder 130 can be performed, but also it is not necessary to remove it one by one, thereby improving workability. Thus, the feeder 107 or the injection feeder 130
As described above, the feeder 107 or the injection feeder 1 is provided below the funnel 11 of the Glen tank 3.
Since the fall regulation guide 136 is provided in the Glen tank 3 above the upper opening 106 (135) of the 30, the fall regulation guide 136 supports the grains in the Glen tank 3 and This prevents the kernels from concentrating and reduces the pressure applied to the upper opening 135 of the feeder 107 or the injection feeder 130. Therefore, the grains smoothly flow into the upper opening of the feeder 107 or the injection feeder 130 to prevent clogging.

That is, since the drop regulating guide 136 is constituted by a pair of inclined plates 136 which are higher at the center and lower at the front and rear or left and right, the fall regulating guide 13
6 supports the upper kernels and as the lower kernels decrease, the inclination causes the kernels above the upper opening 135 to flow in from the side rather than directly above, thus reducing pressure. Will be. Therefore, the drop regulation guide 136 has the function of supporting the grains to reduce the pressure above the upper opening 135 and the function of guiding the grains to the upper opening 135. Since the funnel 11 of the Glen tank 3 is provided with the inspection lid 138 which can be opened and closed freely, maintenance work such as inspection and clogging can be performed from the opening above the discharge part 12 to improve workability. Let it. Thus, the discharge feeding mechanism 100 of the discharge unit 12 is configured such that the drum 101 is detachably attached to the lower part of the funnel part 11 of the Glen tank 3 and the upper part of the feeder 107 is detachably attached to the lower part of the drum 101. Therefore, the disassembly of the drum 101 and the feeder 107 can be facilitated, and the maintenance of the discharge unit 12 can be facilitated. In this case, the Glen tank 3 is configured to rotate laterally with respect to the body side around the lower vertical axis 27 and the upper vertical axis 36, so that when the Glen tank 3 is opened, Makes maintenance easier. That is, since the discharge / delivery mechanism 100 is attached to the funnel portion 11 of the Glen tank 3, it is opened together with the Glen tank 3 to facilitate maintenance.

In this case, the discharge motor 108 for operating the rotating blades 103 is connected to the Glen tank 3 based on the discharge unit 12.
Is provided on the rotation end side distant from the rotation center, so that when the Glen tank 3 is opened, the discharge motor 108 is exposed without the drum 101 being in the way, and the maintenance can be further facilitated. It is suitable. When the side plate (flange) of the rotating blade 103 in the axial direction of the drum 101 of the discharging and feeding mechanism 100 is configured to be detachable, the side plate 71 can be removed to facilitate maintenance in the drum 101. In addition, since the rotor 103 can be removed, maintenance is further facilitated.
