Description

[Detailed description of the invention] A8 Purpose of the invention A. Industrial application field The present invention is directed to picking up grass, rice straw, wheat culm, etc. and using a roll baler to compress and form it into a cylindrical shape. An object of the present invention is to provide a roll baler that has a mechanism that senses the formation of a bale and operates a string winding device.

Conventional technology and its problems A conventional roll baler has a roughly cylindrical bale chamber surrounded by a plurality of rollers installed horizontally between both side walls above the running section, and has an opening at the lower front part of the bale chamber. A pickup device is provided in front of the opening. The bale chamber is divided approximately vertically in half from approximately the center. The front and rear bale chambers are pivoted at the center of the road. The rear part of the bale chamber can swing upwards about a pivot, and during bale forming work, it is pressed and locked toward the front part of the bale chamber by a hydraulic cylinder. Grass or rice straw picked up at the Big Amp is transported to the bale room.

It is compressed into a cylindrical shape in the bale chamber. When the shape of the bale reaches an appropriate size, a force generated on the bale peripheral wall acts in a direction to open the rear part of the bale chamber. At this time, the pressure inside the hydraulic cylinder increases because the rear part of the bale chamber acts in a direction opposite to the pressing action of the hydraulic cylinder. This increase in pressure is replaced by a meter, and by moving the meter pointer, the operator is fully aware that a proper veil has been formed, and stops running the tractor. The string winding device includes string guide means, which means is movable in a guide parallel to the bale chamber gap and extending along the width of one gap, and the string is cut by a cutting mechanism after the string winding process is completed. disconnected by. The operator lets out the string by remote control, and when the end of the string is thrown into the bale chamber, it is gripped by the bale, taken into the bale chamber as the bale goes around, and is wound spirally around the bale by the string guide means, winding it an appropriate number of times. Once it is done, the string is cut and the string winding is completed. By switching the lever of the hydraulic cylinder that presses the rear part of the bale chamber toward the front part to release the pressure, and applying pressure to the hydraulic cylinder that causes the rear part of the bale chamber to swing upward around the pivot axis, the rear part of the bale chamber can be moved forward. is swung upward, an opening is formed for the bale to be ejected outside the aircraft, and the bale is ejected.

When the lever of the hydraulic cylinder is switched again after releasing the bale, the rear part of the bale chamber is again pressed toward the front part of the bale chamber, and the roll baler becomes ready for operation.

C0 Means to be Solved by the Invention However, the roll baler is towed or mounted directly behind the tractor, and the operator watches the state of the harvest collected in a row in the front and the state of pick-up in the rear, and Advanced operating techniques were required, requiring careful attention both forward and backward while operating the tractor, as well as checking the movement of the meter pointer, which indicates the degree of bale formation.

If the picked up state is deflected to the right or left side of the bale chamber, the formed bale will have a truncated conical shape, and the string that was wrapped after forming may come off, or the left and right densities of the bale may be different, so it may be easily deformed after being released. cause inconvenience. In addition, if the meter pointer indicating the degree of bale formation has reached the area where a bale of the appropriate size has been formed, but the harvest is fed to the bale room due to misjudgment or oversight, the density of bales in the bale room may increase. Even if the bale chamber rises and the rear part of the bale chamber is opened, the bale may not be released outside the aircraft, or the pressure generated on the bale peripheral wall and side wall will increase due to the rise in temperature, resulting in damage to the bale chamber or rollers, etc. . In addition, compared to the pressure that presses the rear of the bale chamber, the bale pressure that attempts to swing the bale chamber is small, so the amount of movement of the meter pointer is small, and the pointer is in the area that indicates that the bale has reached the appropriate size. Even if it does, reading it requires a great deal of attention.

B6 Structure of the Invention A1 Means for Solving Problems The present invention aims to solve these problems by using a system in which the pressure generated on the bale peripheral wall when the bale reaches an appropriate size releases the rear part of the bale chamber. When the pointer reaches the area indicating that the rear part of the bale chamber can be opened by a small amount, the switch is fully activated and an alarm sounds to alert the operator.

The worker stops running the tractor. At the same time, the tip of the arm holding the string by the connecting rod linked to the pointer moves to a close position between the bale and the roll, the end of the string is grasped by the bale, and as the bale goes around, the string is attached to the surrounding wall of the bale. Wrap it around.

By converting this movement of the string into the movement of the tip of the arm holding the string, the string moves from the peripheral wall near one side wall of the bale to the peripheral wall near the other side wall, and when it has been wrapped around the bale an appropriate number of times, it is attached to the cutting blade. The string is severed, and at the same time, the arm stops moving. After confirming that the arm has stopped moving, release the lower locking part of the bale chamber and swing the rear part of the bale chamber upward.

An opening for releasing the veil is formed, and the structure is such that the veil is released outside the aircraft. In addition, even if the bale has reached the appropriate size due to an incorrect operation, if the crop is further supplied to the bale chamber, the locking part of the bale chamber will be automatically released, the pressure of the bale will be released, and the rolls and other Prevent damage to parts or the aircraft.

C0 Effects of the Invention Since the present invention is configured as described above, the operator can concentrate on operating the tractor when the harvest is being supplied to the bale chamber, and a bale with a constant density is formed in the bale chamber. At the same time, a veil of appropriate size is formed.

Since a warning sound is emitted to alert the worker, the operator can surely stop the tractor, and the system automatically inserts the string into the bale without having to perform an operation to insert the string into the bale chamber as in the past. When the appropriate number of windings are made, the string is automatically cut and the 7° string winding action stops. When starting to wind the string, the tip of the arm holding the string instantly moves to the optimal position for winding the string, minimizing the time required for winding the string and using only the minimum length of braid, which increases the efficiency of string use. It has a good string winding mechanism, and if a worker wants to check the degree of bale formation, it can be visually checked. Even if the bale is formed to the appropriate size for some reason, the worker can harvest it in the bale room. Even if the bale reaches a predetermined pressure or higher when the bale is fed, the locking parts that engage the front and rear of the bale chamber are automatically released and the bale pressure is released, so the roll baler is not damaged. .
