Description

[Detailed description of the invention] "Industrial application field" This invention picks up straw grass such as grass and straw scattered in a field with a pick-up section and forms it into a roll-shaped bale with a baler section. The present invention relates to a roll baler that is bound by twines supplied from a binding device.

"Prior art" Conventionally, as shown in the specification of Utility Model Application No. 152793/1980,
We have developed a technology to raise and lower the pick-up section by providing a lift lever and a lift adjustment handle.

"Problems to be Solved by the Invention" In the prior art, the position of the lift lever changes by adjusting the support height of the pick-up part using the handle, so it is easy to reduce the space in which the lever is installed and make it more compact. In addition, there were problems in that the lifting lever support structure could not be easily simplified.

"Means for Solving the Problems" However, the present invention includes a baler section for forming a bale, a pick-up section installed in front of the baler section, and a binding device for wrapping twine around the bale, In a roll baler that forms a roll-shaped bale and wraps a twine around the outer periphery of the bale,
A pick-up elevating operation wire whose one end is connected to the pick-up part and raises and lowers the same is connected to the elevating lever, and the outer receiver of the wire is provided on a fine adjustment member screwed onto the elevating adjustment handle. This is a characteristic feature.

``Function'' Therefore, the lever can be installed with a simpler structure than before, and since the lever position does not change due to the operation of the handle, the installation space for the lever can be narrower than before and it can be arranged compactly. Furthermore, the lifting lever support structure can be easily simplified and made more compact than in the past.

a low-speed work position 119 where a bale A forming operation is performed to form a bale A in a bale forming chamber 18 between 17;
A high-speed work position 120 where the bale A between the conveyors 16 and 17 is rotated to wrap the twine 92 around the outer circumference of the bale A, and a twine delivery roll 8
Binding position 12 where the twine 92 is fed out from 7, 93
1 in the lever guide groove 122, and by locking the work clutch lever 11 at the low speed work position 119 of the lever guide groove 122,
The low-speed work clutch 47a and the pick-up clutch 70 are continued to drive the pipe conveyors 16, 17 and the pick-up finger 35 to perform the bale A forming work, while the work clutch lever 11 is locked at the high-speed work position 120. As a result, the pick-up section 4 is stopped, the high-speed work clutch 47b is continued, and the pipe conveyor 1 is stopped.
By driving the bales 6 and 17 at high speed to rotate the bale A at high speed and moving the lever 11 to the binding position 121, the twine 92 is sent out from the delivery rolls 87 and 93, and the twine 92 is attached to the bale A rotating at high speed. 92, the driving speed of the baler part 3 during the binding work of wrapping the twine 92 around the bale A is set higher than the driving speed of the baler part 3 during the forming work of bale A, and each work is performed at the same speed. In addition to shortening the tying time compared to the conventional method, the auxiliary twine feed roll 93 of the tying device 10 is connected to the work clutch lever 11 that controls the driving force of the baler section 3 intermittently. 92 is configured to perform a sending operation. The lever 11 at the bundling position 121 is configured to be returned to the high-speed working position 120 by a spring 137.

Next, as shown in FIGS. 11 to 13, a lever case 123 is fixedly installed on the right side of the engine section 6, and the pick-up elevation adjustment handle 12 is rotatably supported by the case 123, and the threaded portion of the handle 12 is A slider 125, which is a fine adjustment member, is screwed onto the slider 124, an outer receiver 126 that also serves as a detent is fixed to the slider 125, and an indicator 128 that also serves as a detent protrudes from the elongated hole 127 of the case 123. The outer receiver 126

is fixed, and the downward movement of the lever 133 is restricted by a stopper 138 thereof.

The present embodiment is constructed as described above, and the hay picked up by the pick-up section 4 is transferred to the bale forming chamber by the main shaping pipe conveyor 16.
8, the main and sub-forming pipe conveyor 16,
17 is also formed into a rolled bale A.
When the forming pressure of bale A exceeds the set value, the traveling clutch lever 13 is turned off to stop the crawler 2, and the working clutch lever 1
1 from low-speed work to high-speed work, forming chamber 18
The inner bale A is rotated at a higher speed than during this forming operation. Further, by the bundling operation of the lever 11, the twine 92 is started to be delivered from the delivery rolls 87, 93, and the tip of the twine 92 is pushed out in the direction of the bale A by the feeding plate 109, and the twine 92 is dropped onto the upper surface of the conveyor 16 below. The twine 92 is sent to the bale A side. Further, as the tip of the twine 92 is wrapped around the veil A and pulled, the binding clutch 84 is turned on and the twine 92 is pulled.
As shown in the direction of arrow L in FIG. Bale A is moved from the edge to the left edge, and from the left edge to the center during one round trip.
The twine 92 fed out from the rolls 87 and 93 is wound around the outer periphery of the runner 1 through a guide 104 in a spiral manner as shown in 1 to 5 in FIG.
When the runner 03 reaches the end of left-right movement and turns back, the runner 103 remains in contact with one end edge 102a or 102b of the engagement hole 102 while the eight locking pins 101 connected to the chain 80 are in contact with one end edge 102a or 102b of the engagement hole 102, as shown in FIG. The twine 92 at both ends of the bale A is wound multiple times to prevent the bale A from deforming.

As described above, the bale A is formed and tied, and the pick-up part 4 is raised to the road running (non-working) position by operating the lift lever 133, and the pick-up part 4 is lowered to the working position, and the lift adjustment handle 12, the height above the ground of the pick-up section 4 lowered to the working position is finely adjusted.

In addition, by operating the work clutch lever 11, the bale part 3 is driven at low speed when forming bale A, and the bale part 3 is driven at high speed when bundling bale A.
The lever 11 is used to send out the twine 92, and when the bale section 3 is being driven at high speed, the pickup section 4 is stopped.

Further, the twine 92 sent out by the operation of the lever 11 is pushed out in the direction of the bale A by the feed plate 109, falls onto the main shaping pipe conveyor 16 near the bale A in front of the bale A, and also falls on the main shaping pipe conveyor 16 near the bale A.
The twine 92 is sent out to the right side of the machine near 6, and after the starting end of the twine 92 is wrapped around the right side of bale A, the right side end of bale A is tied, and then
