Description

[Detailed description of the invention] The present invention is based on a grain culm reaping processing device, which rotates and handles the grain culm tips inserted into the handling chamber as the grain culm stalks fed from the device are pinched and conveyed through a feed chain. The present invention relates to a combine harvester equipped with a threshing device for handling and processing using a barrel, and a device for tying the waste straw discharged from the threshing device.

A combine harvester is designed to automatically and continuously perform grain culm reaping and threshing operations, but it can be used during harvesting to obtain seed rice or when the grain culm to be harvested is wet. There is a desire to perform reaping and harvesting operations without threshing during harvesting operations. In other words, if the grain culm is threshed immediately after harvesting, so-called live threshing, there is a risk of damaging the husks.In order to obtain seed rice, the grain culm must be dried before threshing. In addition, when wet grain culms are threshed, shell grains may clog the receiving net placed at the bottom of the handling barrel, making it difficult to carry out the sorting process properly. Even in this case, it is preferable to dry the grain culm before threshing.

For this reason, a method has been proposed in which a device for binding grain culms from a grain culm reaping processing device is removably attached to the terminal end of the reaping processing device so as to bind grain culms before threshing. , for this means,
Since a special grain culm binding device is required, the overall structure is expensive, making it difficult to put into practical use.

The present invention has been developed in view of the above-mentioned circumstances, and its purpose is to eliminate the need for threshing grain culms and to improve the process in the subsequent process by making effective use of the original structure and making simple modifications. The purpose is to enable harvesting in a bundled state for easy processing.

A characteristic feature of the waste straw binding device combine according to the present invention is that a mechanism is provided for movably supporting the handling cylinder to a non-handling position while maintaining the feed chain in a conveying state.

Next, the effects of the feature configuration of the present invention will be described.

That is, by moving the handling cylinder to the non-handling position, the grain culms from the reaping processing device can be conveyed through the feed chain and sent to the tying device without being handled.

Therefore, by a simple modification that allows the handling cylinder to be movably supported in the non-processing position, it is possible to effectively utilize the threshing feed chain and the waste straw binding device, without threshing the grain culm. Moreover, it can be harvested after being bundled.
As a result, we have achieved a combine harvester equipped with a waste straw binding device that is even more convenient to use.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Fig. 1, a device 1 for raising grain culms planted in a field, a cutting blade 2 for cutting the base of the raised grain culms, and a rear conveyance device for transporting the harvested grain culms backwards. A reaping processing device 4 equipped with a reaping processing device 3 is provided at the front of the machine, and the grain culm stock base supplied from the reaping processing device 4 is pinched and conveyed by a feed chain 5 with a clamping rail 5A arranged oppositely. A threshing device 7 that handles grain culm tips inserted into the handling chamber A by a rotating handling cylinder 6, a chain 8 that transports waste straw discharged from the threshing device 7 to the rear;
A binding device 9 is provided at the rear of the machine body for tying appropriate amounts of waste straw and discharging it into the field, and a pair of left and right running crawlers 10 are also provided to form a combine harvester.

As shown in FIGS. 1 and 2, a tank 11 for storing shell grains sorted and collected in the threshing device 7 is installed in parallel on the side of the threshing device 7, and The screw 12 that lifts and conveys the grains upward, and the rotating blade 13 that scatters and releases the shell grains conveyed to the upper end of the screw 12 to the upper part of the tank 11 are connected to the lifting shell cylinder 1.
4, and is configured so that the shell grains after threshing can be sequentially collected into the tank 11. Then, a wall 15 is provided in the tank 11 to partition it left and right, and after storing the shell particles in the chamber part a inside the tank, the overflow shell particles are transferred to the outside of the machine body inside the tank. In addition, a screw 16 for transporting shell grains is provided at the bottom of the tank 11 so as to communicate with the inner and outer chamber parts a and b of the tank. A conveying cylinder 17 with a blower is provided to transfer the shell grains to a transport vehicle or the like, and the shell grains are stored in the inner and outer chamber parts a and b of the tank 11, and then the shell grains are taken out. It is possible to select a state in which shell grains are stored only in the chamber portion a on one side and then taken out. in short,
By using only the inner chamber part a of the tank 11 when working in wet fields, etc.,
It is designed to prevent the aircraft from tilting to the left or right.
In addition, when the inside of the tank 11 is divided in this way, the fourth
As shown in the figure, two partition walls 15a, 15a may be provided to partition the chamber into three chamber sections.

As shown in FIGS. 2 and 3, the upper wall 18 of the handling chamber A in the threshing device 7 is configured to be able to swing open and close around the longitudinal axis X, and when the upper wall 18 is in the open state, A pair of front and rear frames 19A and 19B that support the handling cylinder 6 to move it to the upper non-handling processing position are vertically swingable around the axis Y in the front and back direction, and are fixed to the upper position and the lower position by means of pins, etc. The handle cylinder 6 can be moved to a non-handling position while the feed chain 5 is maintained in a conveying state. In short, when harvesting to obtain seed rice or when harvesting wet grain culms, the grain culms can be harvested without being threshed and in a state where they are bundled. still,
When the handling cylinder 6 is moved to the upper non-handling position, the receiving net 20 located below the handling cylinder can be easily inspected and adjusted.

In order to drive the handling cylinder 6, a first transmission belt 23 is provided which interlocks and connects the engine output shaft 22 with a transmission shaft 21 which also serves as a pivot shaft of the front support frame 19A. The support frame 19A is formed into a hollow shape, and a second transmission belt 24 that interlocks and connects the transmission shaft 21 and the handling cylinder shaft 6A is provided inside the support frame 19A.
A tension arm 25 is provided for tensioning and relaxing the handling cylinder 6, so that the driving of the handling cylinder 6 can be stopped when the handling cylinder 6 is moved to a non-handling processing position.

To carry out the present invention, in addition to providing the swinging frames 19A and 19B which can be fixed with pins or the like, a screw type telescopic rod that supports the handling cylinder 6 so as to be able to move up and down in parallel may be provided. For example, installing a hydraulic cylinder that supports vertical movement in parallel.
The handling trunk support configuration can be changed in various ways, and these configurations can be
Collectively called the handling trunk support mechanism.

Further, in order to drive the handling cylinder 6, in addition to providing the transmission mechanisms 23 and 24 using transmission belts, various changes can be made to the handling cylinder driving configuration, such as providing a transmission mechanism using a bevel gear. However, as described in the embodiment, if the drive of the handling cylinder 6 is configured to be able to be switched on and off separately from the drive of the feed chain 5, unnecessary driving of the handling cylinder 6 can be stopped. It's good to get used to it.
