Description

[Detailed description of the invention] (Industrial application field) This invention takes collected materials scattered on the ground, such as cut down grass and threshed straw, from the ground into the bale chamber using a collected material intake device, and rolls them into the bale chamber. This invention relates to a roll baler that compresses and packs into shaped bales.

(Prior art) Conventional roll balers are, for example,
As described in Publication No. 18692 and Publication No. 132952/1983, a pick-up mechanism is provided at the lower front of the bale chamber in which a scraping rod rotates upward to throw away the collected materials on the ground. The collected items thrown away by the pick-up mechanism are placed on the carry-in mechanism and sent into the bale chamber, where they are compressed into a rolled bale and packed.

(Problem to be solved by the invention) In the above-mentioned pick-up mechanism, since the pick-up rod rotates upward, when picking up the collected items, some of the collected items are scattered from above to the sides. There are things to do. In addition, the collected items placed on the carrying mechanism may slip and not be conveyed properly, or may be blown to the side by the wind.

Therefore, as described in Japanese Utility Model Application No. 58-132952, the sides and top of the pick-up mechanism and the carry-in mechanism are covered with covers.

However, since the collected items scattered on the ground may be accumulated in large numbers or dispersed little by little, it is not possible to cover the upper part of the pick-up mechanism and delivery mechanism with a fixed cover as described above. If there is too little, the conveying action will not work properly and the conveyance will not be carried out properly.

(Means for Solving the Problems) Therefore, the present invention is configured as follows so that collected items can be taken into the bale chamber well regardless of the amount of collected items.

That is, in front of the inlet 2 formed in the front lower part of the bale chamber 1, there is a pick-up mechanism 3 in which a scraping rod 17 rotates upward to scrape up collected materials scattered on the ground; In a roll baler collected material carrying-in device which is provided with a carrying-in mechanism 4 disposed between the inlet 2 and carrying the collected material thereon, a mechanism is provided above the pick-up mechanism 3 to prevent the collected material from scattering upward. A first guide body 6 for preventing the collection is provided in a state that is biased downward, and a second guide body 7 that presses the collected items toward the carry-in mechanism 4 is provided above the carry-in mechanism 4 and is biased downward. A collected material intake device for a roll baler was constructed by installing the device in a state in which the material was removed.

(Operation of the invention) Collected items scattered on the ground are picked up by the pick-up mechanism 3.
The collected items are raked upward by the raking rod 17, and are sent onto the carry-in mechanism 4 while being prevented from scattering upward by the first guide body 6, which moves up and down depending on the amount of collected items. The bale is securely conveyed to the inlet 2 while being held between the bale and the second guide body 7 with appropriate strength, and compressed into a rolled bale within the bale chamber 1.

(Effect of the invention) Since the first guide member 6 provided above the pick-up mechanism 3 and the second guide member 7 provided above the carry-in mechanism 4 are separately biased downward, collected items are picked up by the pick-up mechanism 3. The first guide body 6
moves up and down moderately, and the second guide body 7 moves up and down appropriately, and the second guide body 7
Since it moves up and down according to the amount of collected material on the carry-in device 4 without being affected by the movement of
Regardless of the amount of collected items scattered on the ground, the collected items are surely taken into the bale chamber 1 and collection work can be performed efficiently.

(Example) Next, an example of the present invention will be described with reference to the drawings.

A bale machine frame 10 mounted on a traveling machine frame 9 equipped with a pair of left and right crawlers 8, 8 at the bottom and capable of running is rotated upward relative to a fixed half-chamber 11 and this fixed half-chamber 11. It is composed of a movable half-chamber 12 in which the internal bale chamber 1 can be opened rearward and upward.

The fixed half chamber 11 has an inlet 2 to the bale chamber 1.
is opened toward the front and lower side, and a lower bundling conveyance device 13 is provided in the lower part of the inside, and the lower bundling conveyance device 13
A carry-in mechanism 4 is constructed by extending the front end of the inlet 2 from below the introduction port 2 toward the rear side of a pick-up mechanism 3 provided forward. The carrying mechanism 4 is constructed by horizontally suspending rod-shaped conveying tools 15 with scraping claws 15a fixed thereto at appropriate intervals between endless chains 14, 14 stretched over the left and right sides of the fixed half-chamber 11. are doing.

Further, the pick-up mechanism 3 is located at the lower front of the carry-in mechanism 4, and as the cylindrical body 16 rotates, the pick-up mechanism 3 moves the pick-up rod 1.
7 largely protrudes from the circumferential surface of the cylindrical body 16 at the lower front, rotates forward and upward while retracting at the upper rear, and scrapes up the collected objects scattered on the ground and places them on the carry-in mechanism 4.

Above the pick-up mechanism 3 and the carry-in mechanism 4, a plurality of rod-shaped first guide bodies 6 and second guide bodies 7 are provided in the left-right direction of the machine body. The first guide body 6 has the tip 6a side of the pick-up mechanism 3
Intake amount restriction cover 2 installed to cover the upper part of the
2, and its rear end 6b extends above the starting end 4a of the carrying mechanism 4. Also, the second guide body 7
The front end 7a side is fixed to the rear end of the uptake amount limiting cover 22, and the intermediate part 4c is bent downward on the starting end 4a of the carry-in mechanism 4 to press the collected items onto the carry-in mechanism 4, The rear end 7b extends to the inlet 2 of the bale chamber 4.

The first guide body 6 and the second guide body 7 are constituted by elastic rod-like members such as piano wire or leaf springs, and the first guide body 6 is configured according to the amount of collected material scraped up by the scraping rod 17. The second guide body 7 is urged downward with a relatively weak elastic force so that it is displaced upward.
is biased downward with a stronger elastic force than the first guide body 6 so that the collected items are sandwiched between the transport mechanism 4 and conveyed reliably. The second guide body 7 may be a nearly rigid body with a displacement amount of about 10 mm or less depending on the amount of collected items.

As shown in FIG.
A rod-like body made of a rigid body that is intended to rotate up and down about 3 and 24 may be biased downward with its rear end side by springs 25 and 26.
In this case, the spring 25 attached to the first guide 6 is made weaker, and the spring 26 attached to the second guide 7 is made stronger.

The lower bundling transfer device 13 provided in the fixed half-chamber 11 and the upper bundling transfer device 18 provided in the movable half-chamber 12 are connected to endless chains 19, 19, 20, 20 stretched on the left and right sides, respectively. A large number of rod-shaped conveyance devices 21 are horizontally suspended in a structure, and the inner cavities of the lower bundling conveyance device 13 and the upper bundling conveyance device 18 rotate in an arcuate locus, and the collected items are rolled up. This is the outer periphery of the bale chamber 1 which is compressed to a certain extent.

A twine 27 is used to wrap around the bale compressed into a roll in the bale chamber 1, and is supplied into the bale chamber 1 by an appropriate means to be wound around the bale.

Next, the operating state of the above embodiment will be explained.

While the traveling machine frame 9 is traveling, the collected objects are scooped up by the pick-up mechanism 3. Then, the collected items are sequentially pushed downward by the pressing action of the first guide member 6 on the pick-up mechanism 3, compressed, and sent onto the starting end 4a of the carry-in mechanism 4. moreover,
The culm is fed into the bale chamber 1 from the inlet 2 of the bale chamber 1 while being held between the carry-in mechanism 4 and the second guide 7 to prevent it from floating and slipping.

The collected material supplied into the bale chamber 1 is compressed into a rolled bale while being rotated by a lower bundling conveyor 13 and an upper bundling conveyor 18.

After confirming by appropriate means that the collected material has been sufficiently compressed in the bale chamber 1, the twine 27 is fed into the bale chamber 1 and packed, and then moved into the movable half-split chamber 12.
is rotated upward to take out the bale from inside the bale chamber 1 to the outside.
