Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a harvester of a combine harvester and a combine harvester for feeding the harvester of a harvested culm to the threshing section by a scraping foil located at the lower end of the harvester transport chain. The present invention relates to an auxiliary feeding device for grain culms.

[0002]

[Prior art]

 In the conventional combine harvester, the root of the harvested grain culm is scraped by the scraping foil while the threshing part is sent back to the saw by the chain carrier transport chain. At the time of work, leaf sheaths of mud that have come off the harvested culms accumulate and block the transport passages, and in weed fields, weeds become entangled and cause clogging.

[0003]

[Problems to be solved by the device]

 Since the present invention has the above-mentioned problems, the present invention has a simple structure to overcome this problem and facilitate the post-delivery of grain culms to improve workability in wetlands or weeds. It was devised to prevent grain culm wrapping under the scraping foil.

[0004]

[Means for Solving the Problems]

 Therefore, according to the present invention, in the harvesting section of the combine described at the beginning, the feeding action of the stock-source transport chain from the lower side of the scraping foil is provided with the feeding belt facing the culm of the transported grain stem. It is characterized by being provided.

[0005]

[Action]

 With this configuration, the root of the transport grain culm, in which the threshing part is sent back to the crocodile while being scraped by the scraping foil, is guided backward by the feeding belt facing the culm, and with this guidance. Leaf sheaths or weeds to which mud adheres can be discharged to the rear to perform cutting with good workability even in wetlands or weeds.

[0006]

【Example】

 The device according to the present invention will be described below with reference to an example diagram. The harvesting part of the combine shown in the example diagram is a rearward tilting posture in which a few of them are arranged side by side and raised on the ascending side in the path. By the raising tine (7) and the three-row lateral turning type raising case (8), which incorporates the endless chains in which the raising tines (7) attached at the protruding and descending side are attached at regular intervals. Star-shaped scraping foils (3) (3a) and (4) where the roots of the raised grain stalks scratch the straw, and scraping belts (9) (9a) and (10) with protrusions , A cutting blade (11) for cutting the grain culm's stock, and a stock yuan transport chain (1) for transporting the crop vines of the two crops on the left side of the crop culm to the rear and two crops on the same side. The ear tip feeding tine (12) that locks and transports the tip of the grain culm of the above, and the strain source and the edge of the grain culm for one row on the right side are slanted to the left rear. The end of the sending stock carrier chain (1) joins at the end with the stock carrier carrier chain (2) and the tip tip tine (13) where the end of the stock carrier chain (1) joins at the end 3 The vertical conveyor chain (14) for inheriting the strain's stock wawar to the threshing department and the stock yuan raised by the vertical conveyor chain (14) to the threshing department in the proper posture. Equipped with an auxiliary transport chain (15) that can be inherited and a sward plate (16) at the foremost end, so that the cut three-row culms can be sent back to the Y-shape and supplied to the threshing section for threshing processing. It is configured.

It should be noted that the carrying action of the left stock carrier chain (1) is such that the scraping wheel (3a) is bent from the upper side of the chain and extends rearward and is pushed backward by an ammunition machine (17). A rod (18) is installed oppositely, and the right end of the stock carrier transport chain (2) has a starting end of a scraping belt (9a) which extends backward from below and is pressed by an ammunition machine (19). ) Is installed opposite.

Next, the left end of the scraping belt (9) and the starting end of the stock carrier transport chain (1) are composed of the shaft (21) of the scraping wheel (3) which is inclined forward. The shaft (21) is extended downward, and a flat pulley (22) having substantially the same diameter as the sprocket around which the starting end of the stock carrier transport chain (1) hangs around is extended at this extension. The shafts (23) and (24) of each sprocket that are axially mounted and around which the end of the stock yuan transport chain (1) hangs around also extend downwards and have a flat pulley (25) of the same diameter as this sprocket. ) (26) is pivotally attached. Then, the feeding belt (5) is suspended around each of the pulleys (22), (25) and (26), and this feeding belt (5) has the feeding action of the stock carrier feeding chain (1). It faces the culm of the transported grain culm.

[0009] Similarly, the right end of the take-in belt (10) is at the end and the start end of the stock carrier transport chain (2) is at the end of the take-up wheel (4), and the shaft (27) is extended downward. A flat pulley (28) of approximately the same diameter as the sprocket around which the starting end of the stock yuan transport chain (2) hangs is attached to the shaft, and the end of the stock yuan transport chain (2) runs around the sprocket of the sprocket. The shaft (29) also extends downward, and a flat pulley (30) having the same diameter as this sprocket is mounted on the shaft (29). The feeding belt (6) is suspended on each pulley (28) (30). This feed belt (6) is turned and faces the culm of the transported grain culm by the transportation function of the stock carrier transportation chain (2).

Therefore, the grain culms which are laid by the swarding board (16) and raised by the tine (7) have two strips on the left side of the culm belts (9) (9a) and the rake foil. (3) While being scratched by (3a), the stock source is cut off by the cutting blade (11), and is sent after being sandwiched by the stock carrier transport chain (1) and the sandwiching rod (18) opposite thereto. The one on the right side is cut by the cutting blade (11) while being scraped by the scraping belt (10) and the scraping wheel (4), and the stock-source transport chain (2) and the sandwiching rod opposite thereto. It is sandwiched and sent by (20), and the ends meet at the end and are supplied to the threshing section. At this time, it is sent later by the stock yuan transport chain (1) and the sandwich rod (18) on the left side. The grain culm which is sent later by the grain culm, the stock carrier hauling chain (2) on the right side, and the sandwich rod (20) is , The feeding belts (5) and (6), which are in contact with the working surfaces of the feeding belts (5) and (6), move at the same speed as the feeding chains (1) and (2). It is guided backward by this, and along with this guidance, the mud that is scooped at the time of mowing by the cutting blade (11) or leaf sheaths to which the mud falling from the weeds or the grain sticks are discharged backward and become an obstacle in the transport passage. It does not remain.

[0011]

[Effect of device]

 As is apparent from the above description, the present invention is based on the stock carrier chain (1) (2) and the scraping wheel (3) at which the starting end of the stock carrier chain (1) (2) is located below (4) In the harvesting section of the combine, which sends the root of the cut grain culm to the threshing section after the threshing section, from the lower side of the scraping foil (3) (4), the stock source transport chain (1) Since the feeding function of (2) is characterized by being provided with the feeding belts (5) and (6) facing the culms of the transported grain stalks along the armpit, the scraping wheel (3) The stock of the transport grain culm, in which the threshing part is post-fed by the stock-source transport chain (1) (2) while being scraped by (4), is rearward by the feed belt (5) (6) facing the culm. And the leaf sheaths or weeds to which mud adheres are discharged to the rear by being guided to the mud and wetlands. Leaf sheaths and weeds adhered to by the plants do not remain in the transport passages and become blocked, and weeds can be prevented from becoming entangled and do not cause clogging.The simple structure facilitates the transport of grain culms. Mowing with good work performance can be performed.
