Abstract

PURPOSE:To prevent clogging with waste culms when applying a resistance to the foot part of the waste culms by attaching a culm foot resisting board for correcting the culm-discharging posture on the culm foot side of a threshing and culm-discharging machine for conveying the threshed waste culms. CONSTITUTION:This invented threshing and culm-discharging machine on a combine is equipped with a culm discharge unit 1 for nipping and conveying threshed waste culms so as to convey the waste culms in the oblique direction from the foot side of the waste culms to the ear tip side when viewed from the shaft direction of the threshing cylinder shaft 2 and with a culm foot resisting board 3 suspended in the direction almost perpendicular to the direction of the culm discharge unit 1 on the culm foot side of the culm discharge unit 1 so that the lower end part may be freely shaken forth and back.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine threshing and culm device, which is provided with a stock-source resistance plate for giving resistance to a stock-base portion of culm transported by the culm device, for correcting the culm posture, And to ensure worker safety.

[0002]

2. Description of the Related Art The stock root resistance plate of the culm device is provided in the front-rear direction at the position where the tip surface of the stock root slides. When the stock resistance plate is fixed, the jam tends to be jammed due to the resistance.

[0003]

According to the present invention, a culm device 1 for sandwiching and transporting threshed culm is directed from the root side of the culm to the tip side in the axial direction of the threshing barrel 2. Provided to convey in an oblique direction, on the stocker side of the culm device 1, along the direction substantially perpendicular to the direction of the culm device 1, the lower end can be rocked back and forth, A threshing culm removal device of a combine is provided with a hanging stock resistance plate 3.

[0004]

[Advantageous Effects and Effects of the Invention] The culms transported by the culm device 1 come into contact with the stock resistance plate 3 near the holding position of the stock base part during the transportation. 3 swings back and forth and escapes, and does not give excessive resistance to the root part of the culm. A proper resistance is given to the root portion of the culm and the outside portion of the root of the culmination device 1 is covered to maintain safety.

As described above, the stock-source resistance plate 3 is constructed so that the lower end portion thereof can swing back and forth in a direction substantially at right angles to the carrying direction carried by the culm device 1. Since the culm is swung by the contact with the culms near the sandwiching position of the culms that are sandwiched and conveyed by the culm device 1, the resistance to pulling the culms in the culm direction is small, and the jamming of the culms can also be blocked. Less.

[Example] In a combine threshing device, a shank barrel 2 having a shank 4 at the front is suspended in a threshing chamber 5, and an upper side of this threshing chamber 5 is opened and closed around a hinge 6 on the back side. A moving threshing cover 7 is provided, a lowering side is provided with a threshing net 8, a sorting device 9 for accommodating an oscillating sorting shelf and the like, and a rear side is provided with a culvert rack 11 on a suction dust collector 10, By the rear extension 12 of the threshing cover 7, and further by the rear cover 14 and the like which is opened and closed upward around the hinge pin 20 on the back side at the rear side thereof, the drainage chamber 1
5, the culm apparatus 1 is provided in the culm chamber 15 in an oblique direction from the rear end of the threshing feed chain 16 toward the rear of the tip side, and is supported on the culm rack 11. It is configured to be nipped and conveyed by the nipping rod 17 and the culm chain 19 attached to the culm frame 18.

The culm frame 18 has a rear end portion in the culm chamber 15.
It is rotatable up and down around the hinge pin 20 in the front-rear direction with respect to the machine body on the back side, has a transmission case 21 at the front end, and has a bracket 22 that projects the engagement pin 23 downward. A chain rail 24 is provided along the lower side of the exhaust frame, and an exhaust chain 19 is stretched between the front and rear sprockets 25 and 26. The front sprocket 25 sets the transmission gear in the transmission case 21. Through the culm transmission pulley 27
Is transmitted by. This culm transmission pulley 27 is transmitted by a belt 29 from a pulley 28 at the rear end of the handle barrel shaft 2.

[0008] In the culm device 1, a culm belt 30 having a lug arranged along the tip side of the culm chain 19 is stretched,
The rotation of the exhaust pipe 19 is transmitted via the sprocket 62 shaft 31 at the rear end. The tip end side support rod 61 arranged above the culm rack 11 supports the tip side of the culm from below and conveys it by the action of the upper culm belt 30.

The engaging pin 2 at the front end of the drainage frame 18
3, the threshing frame 32 is provided with a pin receiving seat 33, and a pin hole 34 capable of engaging with the engaging pin 23 is formed on the pin receiving seat 33. Can be maintained. Also, the bracket 22 having the engaging pin 23,
It is located below the pressing rod 35 protruding from the side of the threshing cover 7 that opens and closes, and is pressed from the upper side in the closed posture of the threshing cover 7 to prevent the culm frame 18 from floating. Therefore, in order to open the culm frame 18 upward, it is necessary to open the threshing cover 7 first. The opposite is true when closing.

The stock resistance plate 3 may be made of a synthetic wood plate or an elastic plate such as a rubber plate in addition to the sheet metal. This stock element resistance plate 3 hangs down in the midway position of the drainage chain 19 so as to be able to swing back and forth on the upper side of the transfer path of the stock portion,
The plate surface is arranged in a direction orthogonal to the drainage chain 19. The stock resistance plate 3 is attached to the lower side of the upper rear cover 14, and is integrally opened and closed by the rotation of the rear cover 14 around the hinge pin 20, but it can be directly attached to the drainage frame 18. Good. A guide rod 55 is attached to the outside of the chain rail 24, and the tip end of the guide rod 55 is seen through the notch 58 of the stock resistance plate 3 to guide the upper side of the stock of the culm.

The threshing frame 32 includes a rear outer frame 37.
The front and rear frames 36 are provided along the surface.
The frame 40, which extends the frame 38 from the rear end to the rear and is connected to the rear frame 39 of the threshing frame 32,
The rear end is connected to the frame 38 to reinforce the construction of the culm chamber 15 and the frame 38, 40, etc. is provided with a fried machine 42 for accommodating the dehulled grains in the grain tank 41. An auger 43 that supports and grain from this Glen tank 41
Is supported, and the Glen tank 41 is pivotally supported 44 so as to be rotatable to one side. Reference numerals 55 and 56 are frames along the auger 43.

A transmission belt 29 for transmitting the culm device 1
Is the pulley 28 of the handling barrel shaft 2, the pulley 45 provided on the back side along the rear side surface of the rear side frame 39, and the transmission case 2
The spring 47 is stretched over the pulley 27 on the first side.
Tensioned by a tension pulley 46, and by a presser pulley 48 provided near the hinge 6 of the threshing cover 7,
Pressure is applied when the threshing cover 7 is closed. The tip of the spring 47 is attached to the frame 40.

Reference numeral 59 denotes an culm cutter, which is attached to the culm portion at the rear end of the threshing device, receives the culm conveyed by the culm chain 19 or the like in a horizontal horizontal posture, and cuts it shortly. Reference numeral 60 is a cover. Reference numeral 49 is a winding prevention plate, which is inserted into the groove 50 in the central portion of the sprocket 25. The winding prevention plate 49 is fixed to the front end of the chain rail 24, and the left and right chain plates 52 are provided on the sandwiching and conveying side of the culms.
The scraper 51 has a wide width toward the side, and the rotatable pin roller 54 is made of synthetic resin on the circumferential surface of each chain link pin 53 so as not to receive a strong pressure by the winding prevention plate 49. It reduces friction loss.
