Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a device for packing grains from a grain tank provided in a harvester such as a combine into a storage bag.

[Prior art]

Conventionally, in a bag packing tank for grains equipped with a horizontal pulling shutter, the gutter tube is an obstacle when replacing the bag suspended on the bag hook, so the gutter tube provided at the tank outlet should be used. Many proposals have been made to move up and down to open and close the outlet.
(Jpn. Pat. Appln. KOKAI No. 58-18685) [Problems to be solved by the invention] However, the grain bagging device typified by the above-mentioned gazette discharges vertically moving up and down with respect to the outlet of the tank. This is a valve that inserts and removes the cylinder into the bag opening and opens and closes the valve opening for grain extraction.In the bag packing operation, the allowance for inserting the discharge cylinder into the bag and the opening and closing allowance for the valve mouth In view of this, there is a troublesome design in which the discharge cylinder becomes unnecessarily long and a shutter member is required in the tank. In addition, if the discharge cylinder is made long, the tank capacity that has a restriction on the height of the machine body is reduced, and it becomes easy to disturb the bag replacement.

Also, an attempt has been made to make the lower part of the discharge tube rotatable in the bag take-out direction, but in any case, the bag filled with grains is pulled out to the front and removed, and the next bag is filled When it is extended and installed, it must be carried out manually behind the discharge tube in a small space below the tank, and complicated operation is required, which makes bag replacement difficult and inefficient. However, there was a problem such as a danger in changing the bag when the machine was running.

Therefore, in consideration of the actual situation of such conventional bag packing and bag changing work, the present invention provides a feeding tool at the rear part of a discharging tube whose upper part is pivotally supported and whose lower part is movable in the bag taking-out direction. The present invention aims to provide a bag filling device for a grain tank, which can solve the conventional problems and can perform a safe and highly efficient operation by providing the bag filling device in a linked manner.

The rear side of the bag is pushed by the feeding tool 5c and fed forward, and the state shown in FIG. 3 is obtained.

In this state, the opening of the bag 11 is separated from the next bag 11 forward, so that the operator pulls the filled bag 11 forward along the bag hook rod 10 without being disturbed by this. A series of bag filling operations can be smoothly and continuously performed by reattaching the next bag 11.

When the second bag 11 is mounted, the bag front side B contacts the front wall 7a of the discharge tube 7 in the state shown in FIG. 3, and the rear side a is the rear wall 7b and the feeding tool 5c.
It is carried out by feeding it out so as to be in between and opening it, and then lowering the discharge cylinder 7 to the state shown in FIG. 1 [Example] In FIG. 5, A is a combine, which is one rear side of the driver's seat 1. Is equipped with a grain tank 2, a threshing unit B is mounted on the other side, a pretreatment unit C is disposed in front of the machine body, and a culm aftertreatment device D such as a cutter is disposed behind. . A ₁ is a fried grain cylinder, and its discharge port A ₂ is located above the rear inner corner of the tank 2.

The tank 2 is provided with a plurality of funnel portions 2a (FIG. 2) having one grain outlet 3 in the front-rear direction, and each funnel portion 2a is formed in a rectangular shape elongated in the inner and outer directions. It is designed to prevent the tank capacity from decreasing.

Further, 2e is an inspection lid provided on the front upper wall of the tank 2 so as to be openable in a dotted line state, and 2f is a window made of a transparent plate formed on the rear portion of the front wall 2b (FIG. 3).

The trough 4 which is connected to the outlet 3 and hangs downward has a rectangular cross section, and its front and rear walls 4a and 4b are formed in the tank 2.
After inclining inward from the front wall 2b side, the front wall 4a has an arc surface 4c (Fig. 4) centered on a support shaft 5 that is offset to the outside of the lower end of the rear wall 4b of the gutter cylinder 4. To form the higuchi 6.

Reference numeral 7 denotes a discharge tube as a lower gutter tube which is slidably fitted in the gutter tube 4, and its configuration is as shown in FIG.
The front wall 7a forms a circular arc surface having substantially the same radius along the circular arc surface 4c of the gutter cylinder 4, and the lower end of the front wall 7a is cut out in a U shape to form a grain in the rear wall 7b and both side walls 7c, 7d. The discharge port 7e is formed.
Then, the attachment piece 7g having the attachment hole 7f is integrally formed at the upper end of the rear wall 7b, and the discharge tube 7 is supported in the trough 6 by being inserted and attached to the support shaft 5.

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 FIG. 1 or 3 by pushing and pulling the lever 8.

The arm rod 5a is integrally formed with a feeding tool 5c having a space X (FIG. 1) for inserting a bag along the rear wall 7b of the discharge cylinder 7.

The shape of the feeding tool 5c is such that it extends substantially directly below the support shaft 5,
The lower portion thereof is smoothly curved on the side opposite to the upward rotation direction of the discharge cylinder 7, is longer below the bag hook 10 described below, and is shorter than the discharge cylinder 7.

Further, in the embodiment, the rear wall 7b of the discharge cylinder 7 has a mounting piece 7g fixed to the support shaft 5 at the upper portion thereof as a small arc surface facing the arc surface 4c, but the lower surface side thereof is In addition to the straight surface 7h, the lower end is formed with a protruding curved surface 7i (FIG. 1) which is curved rearward.

As a result, it is provided on the mounting frame 9 of the fuselage and protrudes outwardly.
It is designed so that the discharge cylinder 7 can be properly inserted into the grain storage bag 11 supported by the bag-holding rods 10 of the book so that a suitable grain packing operation can be performed.

Reference numeral 12 in FIG. 1 is an adjusting device provided along the lower side of the end of the tank bottom plate 2c forming the take-out port 3 for changing and adjusting the opening width of the take-out port 3 and having the following structure. The amount of grains filled inside is adjusted.

That is, directly above the discharge port 7e, below the tank bottom plate 2c of the take-out port 3 which is slightly biased toward the front side with respect to the opening of the discharge port 7e, and communicates with the arc surface 4c. The adjustment valve 13 formed in an arc shape is moved forward and backward in the elongated hole 15 formed in the side wall of the tank 2 with the operation tool 14 so that the opening amount of the outlet 3 can be easily adjusted. There is.

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 and the grains discharged from the fried grain cylinder A _{1 are} to be packed, if the lever 8 is pulled and the state shown in FIG. Is discharged from the outlet 3 through the gutter tube 4 and the discharge tube 7 to the inside of the bag 11 through the discharge port 7e.

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. Since a large amount of grain 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 has been set, the lever 8 is pushed to move the discharge tube 7 upward and take out the outlet. When 3 is closed and the shutter state is set, the above-mentioned grain content is added to the grain in the bag 11 from the discharge port 7e, and the grain in the bag 11 can be increased in volume to be fully filled.

Further, when the adjusting valve 13 is slid in the elongated hole 15 by operating the operating tool 14 and is projected to the state of the dotted line in FIG. 1 for a long time, the adjusting valve 13 narrows the opening of the outlet 3, and This regulating valve
The opening by 13 causes the deviation to the one side on the front side with respect to the discharge port 7e, and after the grain is filled in the bag 11, the discharge cylinder 7
Also, the grain pressure applied from above to the grains stored in the gutter tube 4 is reduced.

Therefore, the amount of grains in the gutter tube 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 amount of the above-mentioned small amount of grains is added to the grains in the bag 11. Therefore, the work of adjusting the packing of a small amount of grains in a bag can be performed 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 arc surface 4c around the lower end of the rear wall 4b, that is, the support shaft 5 which is biased to the side opposite to the bag take-out side, the bag 11 is taken out from the state shown in FIG. In the state shown in FIG.
Since the grate is closed, the grain in the gutter tube 4 is discharged from the discharge port 7e without spilling appropriately, and the set predetermined amount of grain can be filled in the bag 11.

When the bag 11 is pulled out in the state of FIG. 3, the lower end of the discharge tube 7 is displaced in the bag removal direction,
The space at the rear edge of the bag 11 becomes large, so that the bag 11 can be easily moved along the bag hooking rod 10 and can be easily removed.

Then, when the bag 11 at the next position is unrolled and the discharge tube 7 is inserted into the bag 11 again, if the lever 8 is pulled toward the front, the lower end of the discharge tube 7 easily enters the bag 11 opening smoothly, While expanding the inside of the bag 11 to the rear of the opening by the curved surface 7i,
It is possible to push back the adjacent bag 11 on the bag hooking rod 10 and improve the workability of taking out the bag.

In this state, the rear wall 7b of the discharge cylinder 7 has the straight surface 7h that hangs downward, so that the grain is dropped directly downward to the center of the bag 11 without pushing the bag 11 too much backward. 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 It was devised so that the inner grain can be quickly discharged and the grain can be packed in a bag quickly and accurately.

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 them can be reduced. Since the grain pushed at the inlet opening end of the discharge tube 7 enters the inlet opening of the discharge tube 7 and flows down into the bag 11 in the process, the grain between the discharge tube 7 and the rear wall 4b is also caught. Absent. Therefore, the shutter operation of the discharge cylinder 7 can always be performed smoothly and with good performance.
