Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tine structure of a take-up reel in a combine, which can scrape planted culms on the front side of a mowing section.

[0002]

2. Description of the Related Art In the conventional combine harvester, the tine bars and the mounting portions of the tine are constructed so as to directly contact the grain stems. Therefore, when scraping action occurs
When you grow live or cut soybeans
There is a defect. The culm caused by this is during the tine
It gets in, is entangled around the attachment part and is carried around, scratching
It has caused deterioration of performance. Traditionally, along the rod of the tine
A guide rod that can be moved and adjusted to change the scraping action
The one is known in Japanese Utility Model Publication No. 61-131735, which is
The guide rod may come into contact with the culm and cause further shedding.
is there. Also, as can be seen in the official gazette in Jitsuko Sho 43-2028,
Attaching a tine bar with a protection plate with a semi-circular cross section
It is known that it is provided at the base end. Only
However, this has only the function of preventing winding of the base end,
Cushion effective when tines act on crops to be harvested
It doesn't. Therefore, when harvesting soybeans, the tines
Malfunctions when it comes into strong contact with soybeans and causes shedding
There is.

[0003]

[Means for Solving the Problem] The present invention has the following problems.
For the purpose of solving the problem,
Elastic to wrap both around the mounting base side
A cover body having a force is provided.

[0004]

[Effect of the Invention] Each tine bar, the base end side between each tine, and the mounting portion for the tine bar are enclosed so as to surround them.
Since it is covered with a cover body, the culms that are scratched are covered.
The bar body will come into soft contact first, so
When cutting soybeans, cuts and shattering can be minimized.
Furthermore, the culm may not catch on the base end of the tine.
The rotation of the culm is eliminated.

EXAMPLES Next, examples shown in the drawings will be described.
FIG. 2 shows a plan view of a general-purpose combine, in which a paddy tank section 6 is provided on the lateral side of a threshing section C mounted on a machine body supported by both crawlers 5, 5, and the paddy tank section 6 is A boarding operation unit E is provided in the front. The cutting section B, which is continuously provided in front of the threshing section C via the feeder chamber 7, has a cutting blade 9 horizontally provided at a lower front portion of a scraping auger 8 horizontally provided at a rear portion thereof, and a scraping reel A provided at an upper front portion thereof. Is rotatably mounted on the shaft. This take-in reel A is equipped with both rotary plates 10 on both sides.
Six arms 11a and 11b are respectively extended from the outer periphery of a and 10b in the radial direction, and both arms 11 corresponding to the left and right sides are provided.
The tine cover 12 is fixed to the upper side surface of the tine bar 1 axially mounted between the tips of the a11b by the bolts and nuts 13, and the coil portion 2a formed on the tine 2 made of one iron rod is attached to the tine cover 12. The tips are inserted into and connected to the tine bar 1 so as to come into contact with each other, and the tines 2 arranged in large numbers at predetermined intervals in the lateral direction rotate and revolve during rotation of the take-in reel A. It is installed so that it always hangs down, and is constructed in the same manner as the conventional structure.

Reference numeral 3 denotes an extension tine, which is a cylindrical elastic body 3 serving as an outer side of a coil spring or Bowden wire.
A soft cylinder 3b made of vinyl chloride is fitted around the outer periphery of
A tine 2 is formed so that the tine 2 can be fitted therein, and a Taber screw ring 3c into which the tine 2 can be fitted is welded to the upper end of the elastic body 3a. The tightening body 4 which is a nut having a taper screw can be screwed into the taper screw ring 3c.

FIG . 6 shows a structure relating to the main part of the present application.
There is. This does not have the above-mentioned extension tines.
is there. Here, the surface is smooth due to the elastic force of PVC etc.
In addition, the tines 2 are fitted into the large number of holes 15 formed in the intermediate portion of the cover body 14 up to the intermediate portion, and
Both end sides of are stacked above the tine bar 1 and attached so that they can be locked by the leaf spring clip 16.
Proximal end side of each tine bar 1 and each tine 2 and tine bar 1
The mounting portion for is covered by a cover body 14 having an elastic force.

With this construction, the elastic force is
The cover body 14 has a soft touch against the culms that are scratched.
By coming into contact with them, we can minimize culmination and shedding,
The culm will not be caught on the tine base end side
No whirling occurs. When harvesting soybeans, etc.
It can prevent damage to the yarn and the grain.
