[Industrial applications]

 The present invention relates to a combine for performing work such as mowing, threshing, and bundling, and more particularly to an arrangement structure of an culm sensor in a combine.

[0002]

[Problems to be Solved by Prior Art and Invention]

 In general, some combine harvesters are provided with a binding machine that binds the threshing-treated culm to a predetermined amount and discharges it to the outside of the machine. By the way, since there are various types of culm, there are inconveniences that the bundling position is not constant if the bundling machine is fixed.Therefore, recently, a stock origin sensor for detecting the stock origin position of the culm The one that controls the movement of the binding machine in the direction of the culm based on the detection of is put into practical use. However, conventionally, an culm sensor for turning on and off the operation of the tying machine based on the presence or absence of culm supplied to the tying machine is provided in the culm carrier that conveys the culm from the threshing unit to the tying machine. Therefore, if the culm carrier is stopped during work by raising the pretreatment section, etc., the culm sensor will detect the culm in the conveyance stopped state and maintain the ON state. There was this, and in this case, the binding machine would continue the binding operation despite the fact that the culm was not supplied, so it was necessary to take some measures.

[0003]

[Means for Solving the Problems]

 The present invention was devised with the object of providing an arrangement structure of an culmination sensor in a combine that can eliminate these drawbacks in view of the above-mentioned circumstances. At the terminal end of the culm carrier that transports the culm, a combiner is provided, which is controlled to move in the culm direction based on the detection of the stock origin sensor that detects the stock origin position of the culm, in the combine. In order to provide an culvert sensor for turning the binding machine on and off based on the presence or absence of culms supplied to the machine, the culm sensor is located on the lower side of the end of the culm carrier and in the stock. It is characterized in that it is arranged at a position better than the original sensor. The present invention, with this configuration, can surely prevent the inconvenience that the binding machine continues to operate unnecessarily.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a combine traveling machine body, and the traveling machine body 1 is a pretreatment unit 2 that can freely move up and down for cutting stem culms, a threshing unit 3 for threshing the cut stalks, and a threshing treatment completed. It is provided with a bundling machine 4, a crawler type traveling body 5, etc. for bundling the waste culm, but when the pretreatment section 2 is operated to be raised, the conveyance chain 6 of the pretreatment section 2 and the conveyance of the threshing section 3 are carried out. It is configured to stop the chain 7 and also stop the transport operation of the waste culm chain 8 that transports the waste culms that have been threshed by the threshing unit 3. That is, when the pretreatment unit 2 is operated to be lifted, the transport chain 6 moves relative to the transport chain 7, so that there is no inconvenience in the delivery of the stems due to the movement, which is not shown. The pre-treatment unit clutch is deactivated to stop the conveyance of the pre-treatment unit 2, and the conveyance clutch 9 shown in the power transmission diagram of Fig. 8 is deactivated to stop the conveyance operations of the conveyance chain 7 and the discharge ditch chain 8. It is about to be done.

The binding machine 4 is arranged at the end of the exhaust culvert 6, that is, at the rear end of the traveling machine body 1 so as to be movable left and right. That is, the binding machine 4 includes a transmission case 23 for inputting power from the traveling machine body 1 side, a chain case 11 provided in the power transmission path from the transmission case 23 to the binding machine 4, and a stock arrangement of culms. It is attached to a binding machine unit 13 including a root aligning plate 12 and the like. The binding machine unit 13 has a bracket portion 14 at the upper end connected to the guide rail 10 so as to be movable left and right, and a bracket at the lower end. When the motor 15 is screwed onto the spiral shaft 17 that rotates forward and backward when the electric motor 16 is driven, the lateral movement based on the drive control of the electric motor 16 is possible.

Reference numerals 18 and 19 denote a scraping carrier arranged in parallel between the waste culm chain 8 and the binding machine 4, and the scraping carriers 18 and 19 are supplied from the waste manure chain 8. The waste culms are positively conveyed toward the bundling position of the binding machine 4 by the rubbing operation of the tines 18a and 19a. One of the rubbing conveyors 18 is integrally supported by the guide rail 10. On the other hand, the other take-in carrier 19 is held by the binding machine unit 13 which is movable left and right.

Further, 20 and 21 are a pair of left and right stock origin sensors disposed on the side surface of the scraping carrier 19 on the scraping start end side. The stock origin sensors 20 and 21 are detection levers 20a and 21a. Detects by swinging backwards due to the contact with the culm, but when both stock sensor 20 and 21 are ON, the binding machine unit 13 is moved to the stock side, while When the stock origin sensors 20 and 21 are OFF, the binding machine unit 13 is moved to the tip side. Further, when the stock origin sensor 20 is OFF and the stock origin sensor 21 is ON, the binding unit 13 is stopped. Therefore, the binding position of the binding machine 4 can be made constant on the basis of the stock origin.

On the other hand, reference numeral 22 is a main sensor for turning on and off the operation of the binding machine 4, and the main sensor 22 of the culm is caused by the detection lever 22a swinging rearward by contact with the culm. The presence / absence is detected, but this one is scraped and conveyed so as to be arranged on the lower side in the conveying direction than the end of the drainage chain 8 and on the upper side in the conveying direction than the stock sensors 20 and 21. It is attached to the side surface of the body 18 on the start side of the scraping. That is, since the main sensor 22 is provided on the side of the scraping carrier 18, when the transportation of the waste culm chain 8 is stopped based on the raising operation of the pretreatment unit 2 as described above, the discharge on the stopped waste manure chain 8 is stopped. By the culm, it is possible to prevent the main sensor 22 from maintaining the ON state.

In the embodiment of the present invention configured as described above, when the pretreatment unit 2 is operated to move up during traveling of the machine, the culm draining chain 8 is stopped, and along with this, the stem culm during transportation. However, since the main sensor 22 is arranged on the lower side in the conveyance direction than the end of the drainage chain 8, the main sensor 22 maintains the ON state based on the drainage stopped at the drainage chain 8 position. There is nothing to do. Therefore, it is ensured that the main sensor 22 keeps the ON state and the binding machine 4 is unnecessarily operated while stopping the exhaust culvert 8 based on the raising operation of the pretreatment unit 2. It can be prevented.

Moreover, since the main sensor 22 is disposed at a position closer to the upstream side of the stock origin sensors 20 and 21 in the transport direction, the binding machine 4 may start operating faster than necessary at the beginning of work. There is no. In other words, as in the case where the main sensor 22 is arranged at a separated position such as the culm chain 8, etc., the binding machine 4 is moved to the wrong position based on the detection by the stock sensors 20 and 21 from the state where the culm is not supplied. It is possible to improve the bundling work accuracy by eliminating the inconvenience of movement control.

[0011]

[Operation effect]

 In summary, since the present invention is constructed as described above, the operation of the binding machine is turned on and off based on the detection of the culm sensor, while the culm sensor is discharged as in the past. It is arranged not on the transfer route of the culm carrier but on the lower side of the end of the culm carrier and above the stock sensor. Therefore, even when the culm carrier is stopped during work by raising the pretreatment section, etc., the culm sensor detects that the culm carrier is in the conveyance stopped state and turns it on. As a result, it is possible to eliminate the unreasonableness that the binding machine continues the binding operation even though the culm is not supplied.
