Description

[Detailed Description of the Invention] The present invention relates to a grain bagging device in a combine harvester.

The grain bagging device is configured to supply grains to a grain bag through a grain discharge tube connected to the lower part of a grain hopper that receives grains from a threshing device,
For example, as shown in FIG. 4, two grain discharge tubes 7 are installed at the bottom of the grain hopper 6 along the inside and outside directions of the machine body.
A and 7b are provided, and an outward cantilevered bag support rod 9 that supports the grain bag 8 with respect to these discharge tubes 7a and 7b extends from the body in a series from the inside and outside. The construction is such that a spare grain bag 8' is supported between them, and as soon as the grain bag 8 located outside the machine becomes full, the accompanying bagging worker removes the full bag 8 and , the spare bag 8' located inside is moved to the outside of the machine to the lower part of the discharge cylinder 7b, so that the bagging operation can be carried out continuously.

However, since the above-mentioned bag-packing equipment was designed primarily for so-called two-person work with a bag-packing worker accompanying the operator, it is operated without a bag-packing worker accompanying the bag-packing worker, and all the bags are removed. and grain hopper 6
When the hopper is full, the reaping operation is stopped, and the machine operator himself removes all the full grain bags 8 located inside and outside the machine, replaces the spare bag 8', and bags the grain in the hopper. When you want to carry out work such as taking out grains and then reaping them again, so-called one-man work, if you place the spare bag between the grain bags provided at the bottom of the discharge tube along the inside and outside of the machine as shown in the figure, When taking out a full grain bag from the inside of the machine, the spare bag had to be removed from the support rod, resulting in poor workability. Therefore, when working alone, by positioning a spare grain bag inward of the machine body compared to the grain bags for both the inner and outer discharge tubes, it is possible to avoid removing the spare grain bag from the support rod. This makes it possible to take out the grain bag from the discharge tube, but in this case, it is not possible to make a large space inward of the grain bag from the inner discharge tube, and as a result, the number of spare grain bags supported decreases. However, the frequency of replenishing these spare bags has increased, reducing work efficiency.

Focusing on this point, the present invention makes it possible to obtain a bag support state suitable for both one-person work and two-person work with simple modification, and to support a large number of spare bags in each work state. To make it possible to efficiently collect bags in a desired work style with less frequent replenishment of spare bags.

Next, embodiments of the present invention will be described in detail based on the drawings.

A threshing device 2 is mounted on a traveling machine body 1 equipped with a crawler traveling device, and a threshing device 2 is mounted on the front part of the traveling machine body 1, and a planted stem culm in the field is pulled up and its stock base is harvested, and the harvested stem culm is transferred to the threshing device. A reaping pre-processing section 3 and a control section 4 are installed in parallel, and the control section 4
A combine harvester is constructed by disposing a grain collecting device 5 behind the threshing device 2 for bagging the grains threshed by the threshing device 2.

As shown in FIG. 2, a grain hopper 6 for receiving grains from the threshing device 2 is provided at the rear and upper part of the control section 4, and a grain bagging device located at the bottom of the hopper 6 inside and outside the machine body. Two sets of discharge pipes 7a and 7b are arranged in the front and rear, and one set of discharge pipes 7a and 7b inside and outside are arranged.
A bag support rod 9 for supporting grain bags 8 for a and 7b is extended from the body in a cantilevered manner in a continuous manner from the inside to the outside.

Of the pair of inner and outer discharge tubes 7a and 7b, the discharge tube 7a on the inner side of the machine body has a tube boss portion 1 below the opening 6a formed above the inclined surface of the hopper 6.
0 is fixed in a protruding manner, and a crank-shaped cylindrical body 12 having a long hole 11 formed in its upper part is attached to the boss part 10 so as to be rotatable around the vertical axis P and fixed in position with a bolt 13. At the same time, an overflow cylinder is provided in the opening 6a so that when the amount of grain stored in the hopper 6 becomes larger than the set allowable storage amount, the excess amount flows out into the discharge cylinder 7a on the inner side. 14 is detachably attached.

As shown in FIG. 3, the outer side of the machine is placed so that the spare grain bag 8' is located in the large space formed between the grain bags 8 and the discharge tubes 7a and 7b inside and outside the machine. As shown in Fig. 2, there is a two-person work mode in which only the grain bag 8 is replaced and the inner grain bag 8 is used for overflow, and as shown in Fig. 2, the inner grain bag 8 is used for overflow. Fix it close to the tube 7b,
A spare grain bag 8' is located in a large space formed inwardly from the grain bag 8 for the inner discharge tube 7a, and the overflow tube 14 is removed to remove grain from both the inner and outer discharge tubes 7a and 7b. It is configured so that it can be switched to a one-person operation mode in which the grain bags 8 are replaced at the same time. In addition, the removal of grains from the inner and outer discharge tubes 7a, 7b is stopped by means of respective shutters.

In addition, as a means for changing the position of the discharge tube 7a on the inner side of the machine body, the inner discharge tube 7a may be made flexible, and its form can be changed in various ways.

In summary, the grain bagging device for a combine harvester according to the present invention has two grain bagging discharge tubes 7a located at the bottom of the grain hopper 6 that receives grains from the threshing device 2 along the inside and outside directions of the machine body. 7b, the discharge tube 7a on the inner side of the machine is configured to be able to change its position inside and outside, and an outward cantilevered bag support rod 9 that supports the grain bag 8 with respect to these discharge tubes 7a and 7b is connected to the inside and outside. It is characterized by being provided in.

That is, by making the position of the discharge tube 7a on the inner side of the machine body changeable inward and outward, a large space can be formed on either the outer side or the inner side of the grain bag 8 with respect to the inner side discharge tube 7a. Therefore, a large number of spare grain bags 8' can be placed here, and by supporting as many spare bags as possible in a bag supporting state suitable for both one-person work and two-person work, the frequency of spare bag replenishment can be reduced. It has become possible to carry out grain bagging and collection in a small and efficient manner.
