Description

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

[Prior art]

Conventionally, in a harvester such as a combine harvester or a harvester, the grain stored in a tank such as a hopper is packed into a bag through a gutter, and the grain amount filling adjustment into the bag is made to plunge into the bag. It is known that the lower length of the gutter tube is changed by changing the gutter tube having various lengths or the height of the lower end of the gutter tube is adjusted.

[Problems to be solved by the invention]

When the former of the above-mentioned conventional means, the filling adjustment of the grain is prepared by preparing various gutters with different lengths each time,
There was annoyance that I had to change this.

In the latter case, the structure of the length adjusting mechanism of the gutter tube is complicated, and there is a problem that it is difficult to adopt.

In any of these cases, since the height of the lower end of the gutter tube is changed, the insertion allowance of the gutter tube in the bag varies, and especially when the gutter tube is inserted shallowly, the upper edge of the bag is There is a drawback that it is easy to accidentally come off due to wind or vibration during the bag packing work, which causes loss such as grain leakage and lowers work efficiency.

Furthermore, depending on the type of grain and the condition of wetness, the grain accumulated in the gutter tube causes a large difference in density when pressed upward by the grain group, so it enters the bag when the shutter is closed. Then, even if the gutter tube length is the same, there is a problem that the amount of grains in the bag varies greatly.

In view of the actual situation of the conventional bag packing work, the present invention provides a controllable valve for adjusting the grain pressure in the gutter tube, so that the above-mentioned conventional problems can be solved and the grain with good handling and performance can be solved. The present invention aims to provide a bag filling device for a grain tank.

[Means for solving problems]

In order to achieve the above object, the present invention provides a gutter which opens a discharge port below an outlet of a grain tank and inserts the gutter into a bag to pack the grains. A regulating valve for presetting the opening degree of the outlet is disposed between the outlet and the outlet.

[Action]

Therefore, when the amount of grains to be filled in the bag 11 is adjusted by the bag filling device in the grain tank having the structure of the present invention, the operation tool 14 is operated by fixing the operation in the long hole 15 to the right. Since the valve 13 is located on the right side (for example, the position indicated by the solid line) to open the outlet port 3 largely, the grains stored in the gutter tube 4 and the discharge tube 7 as a movable gutter tube are included in the upward grain group. Since a large amount of pressure is applied to fill the grain in a large amount, this grain portion is added to the grain in the bag, and the bag 11 can be filled with a large amount of grain.

Further, if the adjusting valve 13 is operated in the opposite manner to make the outlet 3 smaller, the outlet 3 is biased to one side from the outlet 7e, and the grain into the gutter cylinder 4 is correspondingly increased. Since there is no pressure on the bag, the bag 11 can be filled with smaller amounts of grain than those mentioned above.

In this way, by changing the degree of adjustment of the adjusting valve 13, the adjusting valve 13 and the take-out port 3 become small in the case of the grains which are easily filled densely in the gutter tube 4 depending on the kind and the wet condition of the grains. On the contrary, in the case of grains that are easily sparsely filled, the outlet 3 is adjusted to be large, so that grains of any condition can be stored in the bag 11 at all times in a quantitative bag. The work of packing can be simplified.

〔Example〕

A is a combine, which is equipped with a grain tank 2 on one rear side of the driver's seat 1 and a threshing section B on the other side, a pretreatment section C in front of the fuselage, and a cutter such as a cutter in the rear. Post-culling processing devices D are provided respectively. A ₁ is a fried grain cylinder, and this 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 having one grain outlet 3 in the front-rear direction, and each funnel portion 2a
Has a rectangular shape that is long inward and outward, and is designed so as not to reduce the tank capacity.

Then, the gutter cylinder 4 connected to the outlet 3 and hung downward has a rectangular cross section, and the front and rear walls 4a and 4b thereof are obliquely provided inward from the front wall 2b side of the tank 2. The front wall 4a is formed with an arcuate surface 4c centered on a support shaft 5 that is eccentrically provided outside the lower end of the rear wall 4b of the gutter cylinder 4 to form a spout 6.

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 is formed with 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 into a U shape with a notch 7j.
The rear wall 7b and the side walls 7c and 7d are provided with a grain discharge port 7
e is formed. 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, so that the discharge cylinder 7 is supported in the trough 6.

Reference numeral 8 denotes 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 an arm rod for fixing an end portion to both sides of the support shaft 5 is provided. By engaging with the elongated hole 5b of 5a and pushing and pulling the lever 8, the discharge cylinder 7 can be rotated to the position shown in FIG. 1 or FIG.

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 its upper portion as a small arc surface facing the arc surface 4c. In addition to the straight surface 7h, the lower end further has a protruding curved surface 7i 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 it can be satisfactorily packed into the bag 11 for storing grains by being supported by the bag-holding rods 10 of the book and carrying out a suitable grain packing process.

Reference numeral 12 denotes 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 and is filled in the bag 11. It controls the amount of grains.

That is, just above the discharge port 7e, the discharge port 7e is slightly biased toward the opening with respect to the opening, and is opened below the tank bottom plate 2c of the mounting port 3 to the arc surface 4c. By moving the adjusting valve 13 formed in a circular arc shape that moves through the elongated hole 15 formed in the side wall of the tank 2 back and forth with the operation tool 14, the opening amount of the outlet 3 can be easily adjusted. Yes.

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 grain cylinder A ₁ , the lever 8 is pulled and the state shown in FIG. From the outlet 3.
It is discharged into the bag 11 from the discharge port 7e 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. 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 to be in the shutter state, the above-mentioned grain content is added to the grain in the bag 11 through the discharge port 7e, and the grain in the bag 11 can be increased to be large and full.

Further, when the adjusting valve 13 is slid in the long hole 15 by operating the operating tool 14 and is projected to a long state in the dotted line in FIG. 1, the adjusting valve 13 is narrowed in the opening of the outlet 3, and Regulator valve 13
The opening due to is displaced 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 pipe 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 cylinder 4 and the discharge pipe 7 is a small amount in a sparse state, and when the discharge pipe 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. Being
This makes it possible to carry out a small-grain bag packing adjustment operation 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 inside of the arc 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 taking-out side, the bag 11 is taken out from the state shown in FIG. In the state shown in FIG. 3, since a large arc is drawn and the outlet 3 is closed at the same time, the grain in the gutter tube 4 is discharged from the outlet 7e without spilling appropriately, and the set predetermined amount is set. The 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 again into the bag 11, if the lever 8 is pulled toward you, the lower end of the discharge tube 7 can easily enter the opening of the bag 11 easily. By the curved surface 7i, the inside of the bag 11 can be expanded after opening, and the rear bag 11 adjacent to the bag hanging rod 10 can be pushed away, and the workability of taking out the bag can be improved.

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 straight down 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. The grain pushed at the inlet opening end of the discharge pipe 7 enters the inlet opening of the discharge pipe 7 in the process and flows down into the bag 11, so that the discharge pipe 7 and the rear wall 4b.
There is no paddy biting between. Therefore, the shutter operation of the discharge cylinder 7 can always be performed smoothly and with good performance.

[Effect of device]

As described above, in the present invention, a gutter which opens an outlet is provided below the outlet of the grain tank, and when the gutter is inserted into the bag to pack the grains, Since the adjusting valve for presetting the opening degree of the outlet is arranged between the outlet and the outlet, it is suitable for various situations such as the type or the wetness of the grain. There is an effect that the filling can be adjusted accurately and the bag filling operation can be continuously performed in which the predetermined amount of grains in the bag can always be kept constant.

Further, since the operation for that purpose is performed without changing the length of the gutter tube, it is easy, and there is no trouble caused by the bag being detached from the gutter tube during the bag packing operation.
