Description

[Detailed description of the invention] The present invention can be applied to grasses etc. that have been cut down in fields.

This invention relates to improvements in a roll baler for compression molding roll-shaped bales.

As shown in Fig. 1, the roll baler A is a towed type body 1 which is towed by a towing vehicle T such as a tractor, or a body which is self-propelled and is equipped with drive wheels. A pickup device 2 that picks up fallen grass, culms, etc., a transfer device 3 that transports the picked up grass, etc. to the rear, and a bale forming room 4 that forms the transported grass, etc. into a rolled bale. In the bale forming chamber 4 of the bale forming chamber 4, the grass G that is sent there is stored, as shown in Fig. 2, Fig. s3, and Fig. 4.
A tight chain 5 is stretched across a tight par 50 for performing zero-compression molding while sequentially rolling it into a roll. When the incoming grass G is wound into a roll with a predetermined diameter and its pressure reaches a predetermined tension, and the tight chain 5 extends beyond the predetermined tension, one fuselage The traveling is stopped and the supply of grass G to the bale chamber 4 is stopped, and while the tight chain 5 is rotated, a binding device (not shown) is activated to wrap and pack the twine, and then the bale forming chamber 4 is moved to the fifth It opens as shown in the figure to release the bale B that has been formed.

By the way, the roll baler A configured in this way is
When trying to increase the degree of compression of the bale B to be formed, the tight bar 50 that spans the tight chain 5 will bend and deform under pressure, so the tight bar 50 should be made thick and strong. In addition, the bearings supporting the tight bar 50 and the guides of the tight chain 5 must be made durable, which increases the overall weight of the aircraft. The problem inevitably arises that the required power also increases.

The present invention has been made to solve this problem that has arisen with conventional means, and aims to provide a new means that can form bales with increased compressed density without increasing the weight of the aircraft. purpose.

Therefore, the present invention was completed based on knowledge obtained through various studies and experiments for the above-mentioned purpose. That is, in order to increase the density of the bale to be compressed φ-formed by increasing the pressure of the tight chain that tightens the pasture, it is necessary to increase the pressure of the tight chain and the tight bars that span it. You will have to replace it with one that is strong enough to withstand it, but if you cut the grass that will be rolled into a roll bale into smaller pieces before rolling and forming it, you will be able to tighten it. The grass itself becomes dense with low porosity, and the grass that has become dense through cutting is fed into the bale chamber and compressed into roll bales. If you continue to do so, you can leave the tight chain for bale forming installed in the bale chamber of the conventional roll baler and the tight bar suspended thereon as they are, and by doing so, it will be possible to use the conventional roll baler. Because we came up with the idea of being able to form roll bales with a much higher density compared to the previous ones, we created a system between the pick-up device of the roll baler and the bale chamber, which picks up the bale and sends it into the bale chamber. When we installed a cutting device to cut and cut the grasses that are coming in, the tight chain and tight bar for bale forming in the bale chamber were
The present invention has been completed by achieving the result that it can be formed into a high-density roll bale without causing deformation or damage due to pressure. The method is characterized in that a cutting device is installed between the pickup device and the entrance of the bale chamber to cut the grass that is picked up by the pickup device and sent into the bale chamber. This paper proposes a roll baler that uses

Next, an example of implementation will be described in detail with reference to the drawings. Note that the same reference numerals as in the conventional means are used for constituent members having the same effect.

Next, embodiments will be described in detail with reference to the drawings. In addition, 1 drawing code is

FIG. 6 is a vertically sectional side view of the main parts of the roll baler A in which the present invention can be carried out. 3 is a transfer device that transports the grass picked up by the pickup device 2 toward the rear of the machine L; 4 is a bale chamber (bale forming chamber) mounted on the rear end of the machine L; ), 5 indicates a tight chain for bale forming installed in the bale chamber 4, and a indicates a cutting device installed between the pickup device 2 and the bale chamber 4.

The machine frame 10 constituting the fuselage l is the same as that conventionally known, and only the outline with the details omitted is shown by chain lines, and the rear machine frame 10a forming the rear half of the bail chamber 4 is hinged. 11, it is pivoted to the front frame 10b of the fuselage l so that it can freely rotate upwardly and rearward.

The pickup device 2 has a rotary shaft 20 horizontally supported on the front end of the machine frame 10, and a large number of toothed rods 21, which protrude in the radial direction when viewed from the side, are arranged in parallel at predetermined intervals in the axial direction. The tooth rod 21 and the tooth rod 21 are mounted around the rotating shaft 20.
The pick-up drums 22 are arranged in parallel in the axial direction, with slit-shaped gaps that allow them to protrude and rotate, corresponding to the parallel tooth rods 21, and are fixed and mounted on the machine frame lO. This is a conventionally known method consisting of the following.

The transfer device 3 connects the rear end side of the pickup drum 22 of the pickup device 2 and the entrance portion 4a of the bail chamber 4.
A large number of strip-shaped shelf boards 30 are arranged at intervals corresponding to the gaps so as to extend and form a large number of parallel slit-shaped gaps provided in the pickup drum 22. The tooth rods 21 of the above-mentioned pickup device 2 are arranged in parallel and fixedly mounted on the machine frame lO.
However, when rotating backward after raking up the grass, the raked up grass is pushed backward along the top surface of the shelf board 30, and the rear end is transferred. The bale is fed into the bale chamber 4 by a roll 31.

The bail chamber 4 is conventionally known and is formed into a chamber having a cylindrical inner cavity with the axial direction as the left and right direction, and has wide inlet portions 4a on the left and right sides along the axial direction at the lower part of the front side. is opened, and its entrance portion 4a is connected to the shelf board 30...
It is connected to the rear end, which is the terminal end of the transfer device 3 formed by. Inside the bale chamber 4, on both left and right sides of the inner circumferential surface of the bale chamber 4, tight chains 5 are stretched so as to rotate endlessly along the inner circumferential surface when viewed from the side, as shown in FIG. They are installed in a pair facing each other on the left and right (one is omitted in the drawing).

The embodiment device constructed in this manner operates as follows.

When the body 1 of the roll baler A is run, the pick-up device 2 installed at the front end of the roll baler A picks up grass and feeds it into the bale chamber 4.
It is rolled into a roll by the tight par 50 installed in the tight chain 5 that rotates inside the bail chamber 4.
It is then compressed to form roll bale B.

At this time, the grasses that are picked up by the pickup device 2 and formed into the roll bale B are fed into the bale chamber 4 through a cutout provided between the pickup device 2 and the entrance portion 4a of the bale chamber 4. By passing through the processing device a, the material undergoes a cutting process, and is sent into the bale chamber 4 in that state.

Then, the grass cut through this cutting process changes from a coarsely piled state to a piled state with a small porosity, increases the density, and is sent into the bale chamber 4.

From this, the bale B that is rolled up into rolls and formed in the bale chamber 4 is formed into a high-density bale B without applying any particular pressure.
When a predetermined tension is applied to the tight chain 5, a high-density veil B is formed.

As explained above, the roll baler according to the present invention is

When the grass is picked up by the pick-up device 2, sent to the bale chamber 4, and formed into the roll bale B, a cutting process is performed before sending it into the bale chamber 4, so that the grass is collected in a densely packed state with low porosity. By feeding the bale into the bale chamber 4, it is possible to form the bale B into a high-density bale B without applying any particular pressure, and the bale B with increased compressed density can be formed without increasing the weight of the aircraft. You will get it.

Furthermore, when Bale B is to be dismantled to be used as feed, the pasture that forms Bale B has already been cut and cut, making it possible to disassemble it without using special equipment such as a bale-breaking cutter. become.
