Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> This invention relates to a grain recovery mechanism in a harvester.

<Prior art> Conventionally, the side of the threshing part of the harvester is integrated with a tip guide plate inclined toward the tip side for guiding bundling and discharging of threshed grain culms (empty culm) and a knot for bundling culms. It is known that the knotter has a mechanism capable of adjusting the binding position by sliding the knotter in the front-rear direction according to the length of the culm to be sent.

Further, in the process of bundling and discharging the empty culm, since the grain (clam grain) left in the empty culm falls from the top of the tip guide plate to the front side (the tip side), there is A collection container (receiving bag) for receiving and collecting falling grains is installed.

<Problems to be solved by the invention> However, in the mechanism described above, the tip guide plate and the knotter are slid back and forth, but the collection bag is fixed to the machine frame side, so the grain falling from the tip guide plate side is fixed. If the grain falls before reaching the collection bag, or if a chute-shaped guide of sufficient length to guide the falling grain to the collection bag side is provided at the tip of the tip guide plate, consider the slide amount on the knotter side. There was a problem that the opening of the collection bag had to be very deep.

<Means for Solving the Problems> The mechanism of the present invention for solving the above problems includes a mechanism capable of moving the knotter forward and backward relative to the machine body 3,
In a harvester in which a guide plate 7 fixed to the knotter side and for guiding the threshed culm 5 in the discharge direction is provided with an inclination to the front, and a falling grain recovery container 23 is arranged at a lower front position of the guide plate 7. A guide chute 27 is provided at the tip of the guide plate 7 so as to guide the fallen grains onto the collection container 23 and drop the grain so that the tip of the guide chute 27 can swing up and down. It is characterized in that the swinging posture is changed.

<Operation> Threshed culms (empty culms) 5 that have been threshed are sent out and bundled on the guide plate 7 of the bundling portion. In this process, the grains dropped on the guide plate 7 or the guide chute 27 are guided by the guide chute. It is dropped from the tip of 27 into a collection container (bag) 23 and collected. When the knotter (bundling portion 6) is slid forward and backward with respect to the machine body, the swinging end (tilt angle) of the swing end of the guide chute 27 changes with the slide, and the guide chute 27 is constantly moved.
The grains from the above fall into the collection container 23.

<Embodiment> The drawings show one embodiment of the present invention, in which a machine body 3 on a machine body frame 2 equipped with a traveling unit 1 is guided to the side of a threshing unit 4 and a threshed empty culm 5 to the right side. Bundling unit 6 that binds into a large bundle and discharges
Is attached. The bundling portion 6 is provided with a guide plate 7 that is inclined toward the tip side and is substantially horizontal in the left-right direction, and a knotter case 8 equipped with a knotter (not shown) is provided on the outer side of the tip end of the guide plate 7.

On the front side (rear part) of the guide plate 7, a packer 9 for standing up the empty culm 5 in the feeding direction is erected, and further, on the tip side of the guide plate 7, a shock is applied to the empty culm 5 on the guide plate 7 so as to grind small particles. Shaking-off claws 11 for dropping onto the guide plate 7 are provided in a protruding manner.
The thresher part side (inner side) of the guide plate 7 receives the clams falling from the empty culm 5 transferred onto the guide plate 7, guides them forward (toward the tip side), and puts them in a recovery bag 23 described later. The chute 12 is obliquely provided in the front-rear direction with respect to the frame 10 below the binding portion 6. 15 is a threshing paddle of dehulled paddy.

A guide rod 13 is supported below the bundling portion 6 so as to incline forward and backward toward the machine body, and supports the bundling portion 6 so as to be movable back and forth. Be sure to attach the binding part 6 to the rear of the guide rod.
An adjustment handle 14 for sliding back and forth along 13 is attached to the mechanism to adjust the bundling position of the empty culms 5.

An output gear case 16 from the threshing unit 4 side is attached to the frame 10 located below the front of the guide plate 7.
The output pulley 17, which is rotatably supported by, drives a pulley 19 which is rotatably supported by a knotting input pulley shaft 18 which is rotatably supported above the pulley. The pulleys 17 and 19 are surrounded by a box-shaped transmission cover 21 fixed to the frame 10.

Further, open ends of a U-shaped container frame 22 are detachably attached to the left and right ends of the frame 10, and a collection bag 23 for falling paddy is attached in the container frame 22, and the collection bag is a guide. Transmission cover at a position lower than the tip of plate 7
It opens upward in front of 21. On the open end side of the container frame 22, the tip is pressed by the transmission cover 21, and the collection bag 23
An elastic body 24 made of rubber or the like is provided so that it can be stably held.

A pallet-shaped guide chute 27 for guiding discharged particles is swingably attached to the tip of the guide plate 7 via a hinge 26, and the bottom surface of the guide chute 27 is always in contact with the upper surface of the transmission cover 21. Therefore, when the binding portion 6 slides back and forth, it swings at the hinge 26 to change its inclination angle, and the swing end of the guide chute 27 always faces the inside of the collection bag 23. Therefore, regardless of where the slide adjusting position of the binding portion is, the grains that have fallen forward from the guide plate 7 do not fall outside, but always fall into the collection bag.

In addition, a plurality of vanes 28 are provided on the rear end surface of the knotter input pulley 19 so as to form a sorting wind toward the front as the pulley rotates, and a large number of louvers are provided at the position corresponding to the pulley 19 of the transmission cover 21. Since 29 is formed, the sorting wind is sent forward through the louver 29, and the straw dust and dust mixed in the grains falling from the guide chute 27 into the collecting bag 23 are removed from the bag by the sorting wind. It has a mechanism to blow it away.

<Effect of device> Since the device of the present invention is configured as described above, even if the knotter is slid in the front-rear direction, the tip of the grain dropped on the guide plate always faces the collection container. With the guide chute whose inclination angle changes, it is surely collected in the collection container. Further, as a result, there is an advantage that it is not necessary to enlarge the input port of the recovery container in consideration of the front and rear slide of the knotter.
