Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a discharge container of a grain bagging apparatus for packing grains from a grain tank provided in a harvester such as a combine into a storage bag. Regarding the improved configuration.

[Prior art]

Conventionally, in a grain bagging tank equipped with a horizontal pull shutter, the gutter tube is an obstacle when changing bags, so the gutter tube provided at the tank outlet is moved up and down to open and close the outlet. Many proposals were made (for example, Jitsuko Sho 58-186).
(See Japanese Patent Publication No. 85).

[Problems to be solved by the present invention]

However, in the grain bagging apparatus represented by the above publication, the discharge cylinder for vertically moving up and down is inserted into and removed from the outlet of the tank, and the valve opening for taking out the grain is provided. It is a valve that opens and closes, and during bag filling work, due to the correlation between the insertion cost of the discharge tube into the bag and the opening and closing cost of the valve opening, the discharge tube becomes unnecessarily long or the shutter is released inside the tank. There is a design complexity that requires a member for use. In addition, when the discharge cylinder is lengthened, there is a problem that the tank capacity which has a restriction on the height of the machine body is reduced and it becomes an obstacle when the bag is replaced.

And, as described above, since the discharge cylinder has a large sliding contact surface on the outer cylinder and must be vertically moved up and down, it is difficult to operate up and down by receiving a large grain resistance in the tank.
Since the discharge cylinder is movable in a direction orthogonal to the bag take-out direction, there is a drawback that the discharge cylinder is difficult to follow and retract during rapid bag replacement, which is an obstacle.

In view of the actual situation of such conventional bag packing work, the present invention has a conventional problem that it is easy to insert and remove the discharge cylinder into and from the bag, and the bag packing work of the grain can be performed quickly and with good performance. The present invention aims to provide a bag filling device for a grain tank that can solve the problems.

[Means for solving problems]

In the grain bagging apparatus according to the present invention for achieving the above object, the discharge cylinder is a grain bagging machine in which the discharge cylinder provided below the shedding tank outlet is inserted into and ejected from the bag supported by the bag hook rod. In the device, the discharge tube is rotatably supported at an upper part by a support shaft provided in the front-rear direction of the machine body at the rear of the bag take-out direction, and the front wall forming the discharge tube is rotated in the bag packing posture. It is formed in a curved arc shape along the direction, and the rear wall is formed by forming a straight surface in the vertical direction.

[Action]

Therefore, in the bag filling work by the bag filling device in the grain tank of the present invention, the lever 8 is pulled toward the front (the direction of taking out the bag 11, that is, the lateral direction of the machine body), and the discharge cylinder 7 is inserted into the bag 11. It is performed in the state shown in FIG. In this state, when the grains discharged from the discharge cylinder 7 and sequentially stored in the bag 11 reach the notch 7j and the discharge port 7e and close the cutout 7j and the discharge port 7e, the discharge cylinder 7 and the gutter cylinder 4 are also filled with the grain. That is, the grain filling amount is a predetermined amount.

When the lever 8 is pushed by the recognition of the above state, the discharge cylinder 7
Uses the support shaft 5 as a fulcrum to move the discharge port 7e along the bag take-out direction, and pivotally displaces it upward, and discharge the grains in the discharge pipe 7 and the gutter pipe 4 downward. The outlet 3 is closed by the front wall 7a of the discharge tube 7.

Next, the filled bag 11 is pulled out toward the front along the bag hook rod 10, the next bag 11 is reattached, and a series of bag filling operations can be smoothly and continuously performed.

In the bag packing operation described above, when the bag 11 is pulled out toward the front in the state shown in FIG. 3 in which the bag 7 is moved up and separated from the bag 11, the lower end of the bag 7 is displaced in the bag taking-out direction. Therefore, the space at the rear edge of the bag 11 becomes large, and the bag 11 and the bag hooking rod 10 can be easily moved and easily removed.

Then, when the next bag 11 is drawn out and the discharge tube 7 is inserted into the bag 11 again, pull the lever 8 toward you and the discharge tube 7
The lower end easily enters the opening of the bag 11 smoothly, and the curved protruding surface 7i spreads the inside of the bag 11 toward the rear of the opening, and separates it from the rear bag 11 adjacent on the bag hanging rod 10.
(FIG. 1), and the workability of taking out the bag can be improved. Then, as the discharge cylinder 7 descends and is inserted into the bag 11, the arcuate front wall 7a pushes the front side of the bag 11 forward and opens it largely, so that good grain filling is possible.

In this state, the rear wall 7b of the discharge tube 7 does not push the rear side of the bag 11 rearward much due to the straight surface 7h that hangs upward and downward. Let it flow smoothly without clogging. Further, the notch 7j formed at the lower end of the arc-shaped front wall 7a facing this does not narrow the opening of the discharge port 7e, and when the discharge cylinder 7 moves upward in a circular arc, 7 Inside grains are discharged promptly, and a rapid and accurate packaging of grains is performed.

Each funnel portion 2a is formed in a rectangular shape elongated inward and outward directions so that the tank capacity is not reduced. Has been taken into consideration.

And as shown in FIG. 1 and FIG.
The gutter cylinder 4 hung downward has a rectangular cross section, and its front and rear walls
4a, 4b (walls arranged in the lateral direction of the aircraft) are the front wall 2 of the tank 2
After inclining inward (toward the center of the aircraft) from side b, front wall 4a
A trough 6 is formed by forming an arcuate surface 4c centered on a support shaft 5 provided on the outer side of the lower end of a rear wall 4b (a wall on the center side of the machine body) of the gutter cylinder 4.

Reference numeral 7 denotes a discharge tube as a lower gutter tube which is slidably fitted in the gutter tube 4, and its structure is as shown in FIG.
The front wall 7a (side wall of the machine body) is formed with a circular arc surface having substantially the same radius along the circular arc surface 4c (Fig. 1) of the gutter cylinder 4, and the lower end thereof is notched 7j in a U shape. Wall 7b and both side walls 7c, 7d
To form the grain outlet 7e. Then, a mounting piece 7g having a mounting hole 7f is integrally formed at the upper end of the rear wall 7b, and is inserted into and mounted on the support shaft 5, whereby the discharge cylinder 7 is supported in the trough 6.

Reference numeral 8 is a lever for operating the discharge cylinder 7, and lever levers 8a, 8a thereof are guided by guide pieces 8b provided on the gutter cylinder 4, and end portions thereof are fixed to both sides of the support shaft 5. 5a slot 5b
When the lever 8 is engaged and disengaged, the discharge cylinder 7 can be rotated to the position shown in FIGS.

Further, in the embodiment, the rear wall 7b of the discharge cylinder 7 has the mounting piece 7g fixed to the support shaft 5 at the upper portion thereof in the arc surface.
Although formed into a small arcuate surface facing 4c, a straight surface 7h is formed on the lower surface side from this, and the lower end portion forms a projecting curved surface 7i curved rearward.

As a result, the above-mentioned discharge tube 7 is inserted into the grain storage bag 11 supported by the two bag hooking rods 10, 10 provided on the attachment frame 9 (FIG. 1) of the machine body and protruding outward. Has been carefully designed so that it can be properly packed and suitable grain packing work can be performed.

Reference numeral 12 shown in FIG. 1 is an adjusting device which is provided along the lower side of the end of the tank bottom plate 2c forming the outlet 3, and which adjusts the opening width of the outlet 3, and is configured as follows. The amount of grains filled in 11 is adjusted.

That is, just above the discharge port 7e, below the tank bottom plate 2c of the take-out port 3 which is slightly biased to the front side with respect to the opening of the discharge port 7e and opened, a circle passing through the arc surface 4c. By adjusting the arc-shaped adjusting valve 13 to move back and forth in the elongated hole 15 formed in the side wall of the tank 2 with the operation tool 14, the opening amount of the outlet 3 can be easily adjusted. is there.

Next, the use of the bag filling device configured as described above is performed in the following manner.

When the discharge cylinder 7 is inserted into the bag 11 to pack the grains discharged from the fried food cylinder A _1, the lever 8 arranged laterally of the machine body is used.
1 to project the discharge tube 7 into the bag 11 to bring it to the state shown in FIG. 1, the upper opening of the discharge tube 7 and the gutter tube 4 communicate with each other, and the grains stored in the tank 2 are taken out from the discharge port 3 Then, it is discharged from the discharge port 7e into the bag 11 through the gutter cylinder 4 and the discharge cylinder 7.

At this time, if the opening of the outlet 3 is enlarged while the adjusting valve 13 is in the solid line state, the grain can be quickly filled in the bag 11, and a large area can be provided for the grain stored in the gutter tube 4 from the above state. A large amount of grains can be stored in the gutter tube 4 and the discharge tube 7 by receiving the grain pressure above the opening of the adjusting valve 13 which is set. Therefore, when the lever 8 is pushed to rotate the discharge cylinder 7 upward to close the outlet 3 and put it in the shutter state, the above-mentioned grain content is added to the grain in the bag 11 from the discharge port 7e, and the inside of the bag 11 is closed. The grain can be increased to make it large and full.

Further, when the adjusting valve 13 is operated by operating the operating tool 14 to slide the adjusting valve 13 in the long hole 15 to project it to the state shown by the dotted line in FIG. , Further adjusting valve 13
The opening due to is to be deviated to one side on the front side with respect to the discharge port 7e, and after the grain is filled in the bag 11, the grain is stored in the discharge pipe 7 and the gutter pipe 4 from above. Reduced grain pressure.

Therefore, the amount of grains in the gutter cylinder 4 and the discharge cylinder 7 is a small amount in a sparse state, and when the discharge cylinder 7 is set to the shutter state as described above, the above-mentioned small amount of grains is added to the grains in the bag 11. In addition, it is possible to perform a small-grain bagging and adjusting operation of the grain easily and accurately.

Further, in the shutter action, the discharge cylinder 7 is the gutter cylinder 4
Since it moves up and down along the arcuate surface 4c around the support shaft 5 provided near the outside of the lower end of the rear wall 4b, that is, on the side opposite to the bag take-out side, the bag 11 is taken out in the direction shown in FIG. From the state to the state shown in FIG.
Since the grate is closed, the grain in the gutter cylinder 4 is accurately discharged from the discharge port 7e without spilling or the like, and the set predetermined amount of grain can be filled in the bag 11.

Further, in the shutter state, the upper end of the front wall 7a of the discharge cylinder 7 is overlapped by drawing a circular arc on the lower side of the adjusting valve 13 or the tank bottom plate 2c, so that the chaff between the both can be reduced and the discharge can be reduced. Since the grain pushed at the inlet opening end of the cylinder 7 enters the inlet opening of the discharge cylinder 7 and flows down into the bag 11 in the process, there is no chaff between the discharge cylinder 7 and the rear wall 4b. Therefore, the shutter operation of the discharge cylinder 7 can always be performed smoothly and with good performance.

[Effect of device]

As described above, the discharge cylinder in the grain bagging apparatus of the present invention is the grain bagging apparatus in which the discharge cylinder provided below the grain removing tank outlet is inserted and withdrawn into the bag supported by the bag hook rod. The discharge tube is rotatably supported at the upper part by a support shaft provided in the front-rear direction of the machine body behind the bag taking-out direction, and the front wall forming the discharge tube is in the bag packing posture and extends along the rotation direction. The back wall is formed in a curved arc shape, and the rear wall is formed in a vertical straight surface.

Therefore, when inserting the discharge tube 7 into the bag 11, the rear wall
While 7b pushes the back side of the bag 11 forward, the front wall 7a attracts the front side of the bag 11 forward to surely open the opening of the bag 11,
The discharge 7 can be inserted into the opening of the bag 11 extremely well, and the rear wall 7b, which is a straight surface when the grain is filled, does not move the bag rear side so much backward, Grains can be smoothly flowed down and filled toward the center without clogging.

When one bag 11 is filled with a predetermined amount of grains, it is necessary to replace it with the next empty bag 11. In this case, the lever 8 is operated to discharge the discharge port 7e of the discharge cylinder 7. Is rotated upward to move the bag to the bag take-out side in a largely oblique shape, and at the same time, the gutter tube 4 is closed to stop the flow of the grain. In this state, the operation of pulling out the bag 11 after filling and the operation of feeding the next empty bag 11 can be performed quickly and easily. Further, the present invention can bring about an effect such that continuous bagging work can be efficiently performed without causing trouble such as rice spillage.
