Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is arranged and mounted behind the threshing section of the body of a harvesting machine, and binds the threshed husk (straw) discharged from the threshing section. As shown in Fig. 1, the knotter in the above-mentioned harvesting machine regarding the improvement of the knotter which is discharged by The deck plate 1 is received by the upper surface of the deck plate 1 of the knock-b arranged in the
A packer that appears from below the deck plate 1 and rotates while being held down from above by a platform 2 that is placed above the latter half of the deck plate 1 and faces the deck plate 1. According to 3,
The bundles are packed in the binding position W at the end of the bundle discharge passage 4 formed between the deck plate l and the platform 2, and tied with a binding string fed out by the needle 5 disposed below the deck plate 1, and then the platform The grain is knotted by a knotting mechanism 6 disposed above the platform 2, and discharged to the rear of the harvester body by a discharge arm 7 disposed above the platform 2, but it is discharged from the threshing section a. of straw,
In order to improve the flow toward the front end 2a of the platform 2 forming the entrance 4a of the bundling discharge passage 4, an endlessly rotating upper surface side of the front half of the deck plate 1 in front of the platform 2 is provided. A raking lug 80 provided on the chê 7 rotates as shown in the arrow in FIG. Attempts have been made to arrange two sets in parallel on the left and right so that they act on each side separately.

By the way, in this case, the straw flowing along the upper surface of the decking plate 1 is pressed down from above by the scraping device 8, and is bent from the pressed position.
When the part next to the pressed part starts to jump upwards and the waste straw flows to the front end 2a of the platform 2, the part of the part where the waste straw starts to jump up becomes the part of the platform 2. When the needle 5 rides on the upper surface of the front end portion 2a, the waste straw is brought in when the needle 5 pays out the binding string, leading to a problem of frequent tying errors.

The present invention has been made to solve this problem, and aims to ensure that the bundling operation is performed reliably by eliminating bundling mistakes while improving the flow of waste straw toward the bundling discharge passage 4. With the goal.

And what about the collection according to the present invention to achieve this objective? J

A pair of raking devices are installed side by side on the left and right, and the straw raking devices are raked by the raking devices at a position above the front half of the deck plate within the left and right spacing between the parallel raking devices. A guide is provided to hold down the middle part of the culm and guide it toward the front end of the platform, and the rear end of the guide is configured to face the front end of the platform. Examples will be described in detail with reference to the drawings. Note that the same reference numerals in the drawings are used for the same constituent members.

In FIGS. 2 and 3, a is a threshing section mounted on the body of a combine, which is a harvesting machine, and only the rear end thereof is shown. C is a straw cutter installed on the rear of the machine in threshing section a to cut and release the waste straw discharged from threshing section a. , by standing up and rotating as shown by the chain line in Figure 2, the threshing part a
This is a normal straw cutter that receives the waste straw carried out by the waste straw transfer device a into the machine frame and cuts it.

b is a no-tar located behind the frame of the straw cutter C and mounted on the rear side of the fuselage of the combine, and is ejected from the threshing section a beyond the upper force of the frame of the straw cutter C. A diffraction plate l that catches and guides the waste straw that is being thrown,
A platform 2 is installed above the cutting and half pieces of the deck play (1) and forms a binding discharge passage w14 between the deck play (1), and a platform 2 is installed from below the deck play (11) to rotate while appearing in and out of the binding discharge passage 4. Packer 3 installed as follows
and a T protrusion 4 provided at the terminal end of the bundle release passage 4.
0 and the T protrusion 40 disposed below the deck plate 1 actuate the clutch by the pressure of the straw packed into the bundling position W at the end of the bundling discharge passage 4 by the packer 3. , a needle 5 disposed above the platform 2 for feeding out the binding string;
A knotting mechanism 6 that ties the tied string fed out by a bill hook 60 and a holder 61, and a release arm 7 that is disposed above the platform 2 and rotates to release when the knotting mechanism 6 has finished knotting. These are the same as conventionally known ones, but the frame b is supported by a support frame f that can be slid left and right and can be mounted on the body of the combine harvester, and its displacement can be adjusted left and right. It is as follows.

Reference numeral 8 denotes a raking device on the stock side, which is disposed above the front half side of the deck plate l in front of the platform 2, at a position close to the stock bottom side of the straw discharged from the threshing section a;
Lugs 80...t-39 are attached to the endlessly rotating chino stretched inside the case 8a, so that the lugs 80... rotate in a posture protruding from the case 8a on the lower surface side of the case 8a. This is a conventionally known device and is arranged at the above-mentioned position by supporting the case 8a on the above-mentioned slidable support frame f. A retractable drive shaft S, which is mounted on the support frame f and supported on the body of the combine, drives the cheno provided with the lugs 80 so as to rotate in the direction of the arrow in FIG. , deck play) 1 acts to sweep the waste straw backward along the upper surface.

Reference numeral 8' denotes a raking device for raking the tip side of the waste straw, which is constructed in the same manner as the raking device 8 on the stock head side, and is discharged from the threshing section a above the front half side of the deck plate l. A case 8d is arranged to be parallel to the raking device 8 on the stock head side at a position closer to the tip of the straw that is coming, and the case 8d is supported by the support frame f, and the drive shaft S Driven.

In addition, 8' is another raking device disposed above the machine frame of the straw cutter C, ahead of the raking device 8 on the stock side, and is constructed in the same way, and is attached to the supporting machine frame f. It is supported and driven by a drive shaft S.

Reference numeral 9 denotes a guide disposed above the front half side of the decking plate 1 within the lateral spacing between the raking device 8 on the stock side and the raking device 8 on the tip side. The front end 2a of the platform 2 is formed long on the left and right so as to fill the gap between the raking devices 8, and the middle part of the culm of the straw that is raked by the raking devices 8 is pressed down. In order to guide the guide 9 toward the In order to transfer the waste straw to the lower surface of the front end 2a of the platform 2, it is placed at a position connected to the front end 2a of the platform 2. This guide 9 is connected to the case 8 of the scraping device 8.
It is fixed at the above-mentioned position by appropriate means, such as being supported by spanning the platform 2a and 8a, or by being supported by the front end 2a of the platform 2.

The knotter in the collector I1 according to the present invention constructed as described above operates in a linear manner.

Straw discharged from the threshing section a and caught on the upper surface of the deck plate l of the knock-b is installed in rows on the left and right above the front half of the deck plate 1. The device 8 and the tip-side scraping device ff18' scrape backward while being pressed against the upper surface of the deck plate l.
Since the straw is transferred toward the front end 2a of the platform 2 constituting the entrance 4a of the bundle discharge passage 4, the flow of waste straw toward the entrance 4a of the bundle discharge passage 4 is smoothed.

At this time, the part of the straw that receives the raking by the raking device 8 is pushed downward toward the upper surface of the deck plate 1, and the culm is bent, so that the culm is bent toward the plant base. The tip side and the middle part of the culm located between the raking device 8 and the raking device 8' come to float upward; While being pushed downward, the guide 9 disposed within the space of 2 is guided toward the front end 2a of the platform 2, and the receiver is passed to the front end 2a.

Therefore, according to the means of the present invention, even if the raking device is disposed facing the upper surface of the front half of the deck plate, the culm of the straw is bent and floats up to ride on the upper surface of the platform. This eliminates the problem of waste straw being brought in when the needle feeds out the tying string, eliminating tying errors, and smoothing the flow of the machine toward the entrance of the tying release passage, while also allowing the knotter to avoid tying errors. can get.
