Description

[Detailed description of the invention] (Industrial application field) The invention has an internal bale chamber that compresses harvested materials such as cut down grass and rice straw left in the field after threshing into rolled bales. This invention relates to a self-propelled roll baler in which a baling machine frame is provided on a machine base equipped with a self-propelled traveling device.

(Prior art) A roll baler that compresses harvested material into a roll shape has a bale chamber that compresses harvested material into a roll shape, as described in Japanese Utility Model Publication No. 67-45792 and Japanese Utility Model Application Publication No. 58-18692. Generally, the machine is equipped with a machine that is towed by a tractor.

However, this tractor-pulled roll baler is large and has a long body, making it difficult to turn around and making it difficult to use for collection work in narrow fields.

For this reason, the present applicant installed a baling machine frame with a bale chamber inside on a machine base equipped with a self-propelled traveling device, and installed a pick-up device on the front side of the baling machine frame to pick up harvested material from the ground. A self-propelled roll baler is provided with a driving unit with a built-in prime mover and a control tool on the rear side of the baling machine frame, so that an operator can collect harvested crops while walking behind the driving unit. , already filed a patent application in 1971-71934.
No. (Japanese Unexamined Patent Publication No. 59-196012) Publication and Application No. 1987-
No. 196580 (Utility Model Publication No. 59-98752) was filed and proposed.

(Problems to be Solved by the Invention) The above-mentioned self-propelled roll baler opens the bale chamber which can be opened and closed by opening the bale outlet provided at the rear upper part of the bale machine frame, and transfers the bales in the bale chamber to the driving unit. The bale in the bale chamber can be taken out over the top of the pick-up device and taken out to the ground at the rear or left and right sides of the machine, or the front supply port of the bale chamber can be opened wide upward and the bale can be taken out over the top of the pick-up device and taken out from the machine. It is arranged so that it can be taken out above the ground on the left and right sides of the vehicle.
Therefore, there was a problem in that the driving part and the pick-up device became an obstacle to removing the bale, making it difficult to remove the bale.

(Means for solving problems) For this reason, the present invention is constructed as follows.

That is, on the machine base 2 equipped with the traveling device 1,
A baling machine frame 6 is provided, which has a bale chamber 4 therein for compressing harvested material into a roll shape.
In this self-propelled roll baler, a pick-up device 7 for picking up crops from the ground is provided on the front side of the baler, and a drive box 9 and a control device 25 are provided on the rear side of the baling machine frame 6. An openable and closable bale take-out port is formed in the lateral side of the bale machine frame 6 so that the bale can be taken out directly to the lateral side of the bale machine frame 6.

(Operations and Effects of the Invention) The work of collecting crops is carried out by an operator who is located behind the drive box 9 and operates the operating device 25 to move the traveling device 1 while moving the baling machine frame 6.
The harvested material picked up from the ground by the front pick-up device 7 is taken into the bale chamber 4 in the baling machine frame 6 and compressed into a rolled bale.
When the bale 3 is compressed, the traveling device 1 is stopped, the bale outlet provided on the side of the bale machine frame 6 is opened, and the bale 3 in the bale chamber 4 is directly taken out to the ground on the side of the machine body. It turns out. This operation of taking out the bale 3 does not require going beyond the drive box 9, pick-up device 7, etc., as in the past, so there is no need to lift the bale 3 high, and the bale 3 is directly placed on the side of the bale machine frame 6. Since it can be taken out, the work becomes extremely easy.

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

A machine base 2 equipped with a traveling device 1 consisting of a crawler
A bale machine frame 6 is provided above, and this bale machine frame 6
A pick-up device 7 is provided on the front side of the bale machine, and a feed conveyance device 8 is provided between the pick-up device 7 and the bale machine frame 6. Further, on the rear side of the bail machine frame 6, a driving box 9 containing a prime mover is provided, and on the driving box 9, a control tool 25 for controlling the traveling device 1 is provided.

In the pick-up device 7, a cylindrical drum 10 having approximately the same length as the width of the machine base 2 is installed horizontally so as to be rotationally driven. As it rotates, it rotates upward while appearing and retracting from the outer circumferential surface, picks up the harvested material on the ground upward, and takes over and supplies the harvested material to the front end of the rear feed-up conveyance device 8.

The feed conveyance device 8 has a wide conveyance belt 12.
A large number of conveyor claws 13 are installed upright in the baler frame 6, which is stretched between the pick-up device 7 at the lower front and the supply port 15 of the baler frame 6 at the upper rear, and transports the harvested material picked up by the pick-up device 7. It is placed on the belt 12, sent up, and fed into the bale machine frame 6 through the delivery passage 14 and from the supply port 15.

The bale machine frame 6 includes a fixed machine frame 16 fixed on the machine base 2 and a movable machine frame 17 that can be rotated upward as appropriate.
It consists of

Inside the fixed machine frame 16, there are semicircular side walls 1 at the front and rear.
8, 18 are provided, and endless chains 19, 19, in which the bale chamber 4 side of the inner cavity moves in an arc shape, are stretched back and forth along curved rails (not shown) provided on the outer periphery of the semicircular side walls 18, 18. A large number of transport rods 20 are horizontally suspended between the front and rear endless chains 19, 19 at appropriate pitches.

The inside of the movable machine frame 17, like the inside of the fixed machine frame 16, includes front and rear semicircular side walls 21, 21, endless chains 22, 22 that move in an arc shape around the outer periphery of the side walls 21, and the endless chain 22. ,22
It consists of a large number of conveyor rods 23 horizontally suspended at appropriate pitches between them, and the bale machine frame 6 is sprung upwards around the sprocket shaft 5 horizontally suspended in the front-back direction of the upper part.
A bale outlet is opened in the lateral side of the bale chamber 4 so that the bale chamber 4 inside is opened to the side.

24 is a handle for flipping up the movable machine frame 17.

As shown in FIG. 2, the mating surfaces of the fixed machine frame 16 and the movable machine frame 17 are slanted from the upper left to the lower right, so by opening the bale chamber 4,
The internal veil 3 will roll out to the right.

Note that the opening direction of the veil chamber 4 may be to the left, which is opposite to that shown in the drawing.

Harvest collection work will be carried out as follows.

While operating the operating device 25 to run the traveling device 1, the pick-up device 7 picks up the harvested material from the ground, and the feed conveyance device 8 sends it to the supply port 15 of the baling machine frame 6 and into the bale chamber 4. The supplied harvested material is compressed into a roll shape while being rotated by transport rods 20 and 23 that move in an arc around the outer periphery of the bale chamber 4.

When the bale 3 is compression-molded to a predetermined pressure with the same diameter as the inner diameter of the bale chamber 4, a string supply device (not shown)
The string is supplied into the bale chamber 4 and wrapped around the outer periphery of the bale 3 for packing. Thereafter, the movable machine frame 17 is rotated upward to cause the packed bale 3 to roll out to the side of the machine stand 2.

In the illustrated embodiment, the operator moves the traveling device 1 while walking behind the drive box 9, but a riding platform is provided protruding from the machine base 2 toward the rear of the drive box 9. The traveling device may be driven while the worker is sitting on the riding platform.
