Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a harvester knot that collects and binds a plurality of bundles of straw discharged from the culm opening of a threshing device.

(b) Conventional technology Conventionally, grains were threshed using a threshing machine mounted on a machine stand.
A plurality of straw bundles discharged from the culm opening of the threshing device are handled with the needle and packer at the bottom and the knot and discharge arm at the top, and the clutch case, knot and discharge arm are used to handle the straw ear side. Harvester knots are already known in which the knots are tied together by means of a bypass transmission.

(c) Problems to be solved by the invention The known harvester nozzle has the puller, needle, and door shaft protruding to the side opposite to the detoured transmission device, and the nodule, discharge arm, etc. faces the parker, needle, etc. Therefore, in order to have the pack car face the area corresponding to the middle part of the discharged straw bundle, the clutch case or the detoured transmission device had to be attached to the outside of the No. 4 funnel. As a result, the left-right balance of the aircraft deteriorated.

Further, the needle shaft and the puller shaft protruded from one side of the clutch case, and the shaft for driving the knot shaft protruded from the other side, resulting in poor maintainability.

(d) Means for solving the problem The present invention is to install the knotter outside the culm of the threshing device mounted on the machine stand, with the clutch case, needle and pucker at the bottom, and the nodule and discharge arm. The clutch case, which is installed in the upper position and is equipped with a clutch for intermittent power to the needle and the knot when the knot is activated, and the knot are connected by a transmission device bypassing the stock side, and the needle, By arranging the packer, the door, the knot, and the release arm on the stock side of the clutch case, and forming a guide passage on the ear side on the clutch case, the above-mentioned problems can be solved, and the knotter can be made more compact. The aim was to reduce costs.

(E) Function The stock side of the bundled grain culms is conveyed by being held between the feed chain and the starting end of the pinch rail, and the ear side is inserted into the supply port for threshing.

The part of the straw bundle discharged from the culm near the stock end is raked into the collecting section by the bushing car, and the panicle side is raked out by the rotating blade and transferred to the panicle collecting part.
When it is focused to a predetermined amount, it is bundled and released.

Since the shaft that transmits power to the needle, packer, and knot of the knot protrudes from the clutch case toward the base, the entire knot including the clutch case should be brought close to the aircraft on the base side, where it will not interfere with the No. 4 funnel. In addition, the front-rear balance is not deteriorated more than when the transmission device and clutch case are disposed on the stock side, and the top of the clutch case can be used as a guide path for the ear side.

(F) Example An example of the present invention will be explained with reference to the drawings.

is the shaft 3 protruding from the clutch case 26 toward the stock side.
It is attached to 0a and faces the police car 16.

The front and rear wall plates 7a, 7 of the fourth funnel 7 are
A blade 32 is mounted on a hollow shaft 31 rotatably supported on a.
A spline shaft 38, which protrudes forward from the clutch case 26 and serves as an input shaft, is fitted into a spline portion attached to the rear of the hollow shaft 31 so as to be assembled together. A sprocket 33 fixed to the front end of the transmission shaft 1
1a, the blades 32 are rotated by the sprocket 33a through the chain 35 so as to scrape the ear side of the straw bundle discharged from the discharge culm opening 6, and the guide rod 36 protruding from the upper outer side of the fourth funnel 7 is Support and guide the ear side of the straw bundle.

Furthermore, the upper surface of the clutch case 26 is formed as a guide surface that supports and guides the middle part of the straw bundle that the packer 16 is raking, and the outer part of the collecting plate 39 screwed onto the ear side of the clutch case 26 is is auxiliary door 3
7, and a collecting plate 40 is provided on the side of the stock from the clutch car 16, and the clutch case 26 is divided into parts shown by chain lines, and bolts 41,
