Abstract

PURPOSE:To enable the change of the longitudinal position of a grass-separating and raking apparatus is synchronization with the longitudinal change of the position of a raking reel corresponding to the lodging state of culms by making the grass-separating and raking apparatus longitudinally shiftable. CONSTITUTION:A grass-separating and raking apparatus 13 is supported by a grass-separation member 14 and a transmission case 16. The transmission case 16 is longitudinally swingable around an auger shaft 15. The position of the grass-separating and raking apparatus 13 is changeable in longitudinal direction by the extending and contracting action of a hydraulic cylinder 18 inserted between the grass-separation member 14 and a reaping frame. The grass-separating and raking apparatus 13 is interlocked with the longitudinal shift of the raking reel 4 in such a manner as to synchronously drive hydraulic cylinders 10, 18 to shift the apparatus 13 in synchronization with the longitudinal shift of the raking reel 4.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is provided with a reel for scraping planted culms at the front part of a reaping section, and a reel for reaping the raked culms and cleaning the culms after cutting. This invention relates to a conventional combine harvester that transports and supplies the entire grain to a threshing section for threshing.

Prior Art and Problems In this type of ordinary combine harvester, there is a vertically rotating weed raking device located in front of the lateral side of the raking reel, which controls the weeding action of the culm to be reaped and the culm not to be reaped. Devices equipped with such devices are known.

Generally, the position of the raking reel is changed back and forth depending on the ups and downs of the culm in the field.

For example, if the culm is lodging, the raking reel is moved forward and lowered so that the reel tines are close to the field surface to improve the raking performance for the culm. I have to. However, if the weed raking device is set at a predetermined position as in the past, the function of raking up and raking the grass against the lodging culm does not work satisfactorily, resulting in a decrease in performance.

In view of this, the present invention is designed to change the position of the weeding device back and forth in accordance with the change in the back and forth position of the raking reel.

A means for solving the problem, that is, a technical means according to the present invention, includes a raking reel 4 for raking the tip side of the culm planted in the field at the front of the machine body equipped with the threshing part 2; In an ordinary type combine harvester equipped with a reaping device 5 for cutting off the stock base of the raked culm and a device for conveying and supplying the entire cut culm to the threshing section, the side of the raking rule 4 is provided. This is characterized in that a vertically rotatable grass raking device 13 is provided at the front of the section, and the position of this grass raking device 13 can be changed in the front-rear direction.

Operation According to the above-mentioned configuration, even if the raking reel 4 is moved back and forth depending on the lodging condition of the culm in the field during the reaping operation, the weed raking device 1f' 13 is synchronized with it. The position can be changed back and forth.

Effects of the Invention Therefore, according to the present invention, the position of the weeding raking device can be changed synchronously with the change in the front and back position of the raking reel, so that a predetermined relative position between the two can be secured. Therefore, the weeding function is performed well and reliably as expected.

EXAMPLE Hereinafter, one example of the present invention will be described based on the drawings. A threshing section 2 and a control section 3 are disposed on a machine body equipped with a crawler traveling device 1, and in front of the machine body there is a reel 4 for raking the tip side of the shell culm planted in the field backward, A reaping device 5 that cuts the stock base of the cut culm, and a collection auger 6 that receives the cut culm, collects it in the lateral direction of the machine, and sends it out to the rear.
, and a reaping section 8 equipped with a feeder 7 for transporting and supplying the entire reaped husk culm into the handling chamber 2a of the threshing section 2.

The raking reel 4 is configured so that it can be driven up and down relative to the reaping frame, but it is also configured so that its position can be changed in the front and rear directions. The change in the position of the scraping reel in the front-rear direction is controlled by a hydraulic cylinder 10 that is telescopically operated by switching a control valve using an operating lever 9.

At the front of the lateral side of the scraping reel 4, there is a vertically rotating scraping claw 11 which is configured to move from the front lower part to the rear upper part with the scraping claw 11 protruding from the chino in the case 12 toward the front in the direction of movement of the aircraft. A type of weed raking device 13 is installed.

The starting end side of this weeding device 13 is supported by the weeding body 14, and the terminal end side is supported by the shaft 1 of the collection auger 6.
It is supported by a transmission case 16 which houses a transmission device connected to the transmission case 5 so as to be rotationally driven.

The transmission case 16 is configured to be able to swing back and forth using the auger shaft 15 as a fulcrum. It is configured so that its position can be changed in the front-rear direction. Correspondingly, when the weed raking device 13 is moved forward, the inclination becomes gentle, and when the grass raking device 13 is moved backward, the inclination becomes steep, which is adjusted by the rocking displacement of the transmission case 16. ing. Further, this weed raking device 1t13 is configured to communicate with both sleeve pressure cylinders 10.18 so as to move back and forth in synchronization with the longitudinal adjustment of the raking reel 4.
