Field of the Invention The present invention relates to a pickup device for picking up grasses and straw culms cut down in a field on a self-propelled vehicle body, and a roll for collecting the collected materials. The present invention relates to an improvement in a self-propelled roll baler equipped with a bale chamber for forming and packing into a veil shape.

[0002]

2. Description of the Related Art In a self-propelled roll baler, as means for taking out a bale which has been formed into a roll and packed in a bale chamber outside the machine, a conventional means is shown in FIG. 1 and FIG. There are means, means shown in FIG. 3, and means shown in FIG.

A first means shown in FIGS. 1 and 2 mounts a pickup device 1 on a front end side of a vehicle body a which travels by itself by a driving operation of a walking and following operator, and mounts the pickup device 1 behind the pickup device. In the walking type self-propelled roll baler A provided with a bale chamber 2 having a bale forming device (not shown) on the upper surface of the vehicle body a, the pickup device 1 and the bale forming device are combined with the vehicle body a. a, and the walking device 3 is driven to drive the vehicle body a, and the grass and straw culms, etc., which have been cut down in the field are collected by the pickup device 1 and the bale room 2 is driven. And the collected material is sequentially formed into a bale by a bale forming device. When the bale B of the collected material reaches a predetermined diameter, the vehicle body a
Is stopped, the bale B is idled, and packing is performed by feeding out twine (not shown). When the operation is completed, first, the operator M first moves the rear of the cockpit 4 on the rear end side of the vehicle body a. Away from the position, as shown in FIG. 1, the vehicle goes to the front end side of the vehicle body a, where the upper chamber 2a of the bail chamber 2 is turned upward to open the bale chamber 2.

Next, from this state, the operator M holds the bail B with both hands, pulls it out toward the front side of the vehicle body a, and takes it out of the machine.

Next, when this operation is completed, the open upper chamber 2a is returned to the closed state as shown in FIG. 2, thereby completing the operation of removing the bale B.

In the second means shown in FIG. 3,
One side wall 2b of the bale chamber 2 mounted on the vehicle body a of the walking type self-propelled roll baler A is formed as a door that can be opened and closed by a hydraulic cylinder, and the formation and packing of the bale B are completed. When the side wall 2b is opened and rotated by the hydraulic cylinder, the bale B which has been formed in the bail chamber 2 is pulled out to the side of the vehicle body a, and the bale B is taken out of the machine. The side wall 2b is closed and rotated by the hydraulic cylinder, and the removal of the bale B is completed.

A third means shown in FIG. 4 is a bale chamber 2 mounted on a vehicle body a of a walking type self-propelled roll baler A.
Is configured such that the rear chamber 2c is opened and rotated rearward and upward, and when the forming and packing work of the bale B in the bale chamber 2 is completed, the operator M The rear chamber 2c is turned back and manually opened and rotated, whereby the bale B that has been packed in the bale chamber 2 is dropped below the bale chamber 2 and then the rear chamber is opened and rotated by the operator. An operation of closing and rotating 2c is performed to complete the unloading operation.

[0008]

In the above-mentioned prior art, the first means shown in FIGS. 1 and 2 and the second means shown in FIG. Thereafter, the bale B that has been molded and packed is manually taken out of the bale chamber 2 and then the bale chamber 2 is closed. Therefore, it is difficult to take out the formed bale B manually. Problems have arisen.

This is because the bale B formed by feeding the collected material into the bale chamber 2 and winding it into a roll, tightening it and packing it with twine has a considerable weight. The fact that the package is tightly packed and the position where the bale B is removed is low, making it difficult to remove the bale and requiring heavy labor. In addition, the large number of bales being formed increases the labor burden. by.

In the third means shown in FIG. 4, the bale B which has been formed in the bale chamber 2 is opened and rotated from the rear chamber 2c so that the bale B moves downward from the bale chamber 2. Although the discharge operation has been performed by dropping, in this state, the rear chamber 2c opened and rotated
When the take-out operation is to be completed by closing the bale B, the closing rotation cannot be performed by the rear chamber 2c being used by the bale B dropped on the ground surface. It is necessary to move it to the side, and in the actual work, as in the case of the first means and the second means described above, a heavy labor burden is imposed.

Further, in this means, the rear chamber 2c is opened and rotated to form and form in the bail chamber 2.
When the packed bale B is dropped and released, the vehicle a
By moving the vehicle forward, the veil B can be brought to the rear of the vehicle body a, but in order to do this, the vehicle b When operating the vehicle to move forward, the veil B that has been dropped and released interferes with the operation of the vehicle body performed by the operator located behind the vehicle body a, so that the veil B must be moved sideways. Eventually, similarly to the first means and the second means, an operation of moving the heavy bale B at a low position is required, and a heavy labor load is imposed.

The present invention has been made in order to solve the problem that occurs in the conventional self-propelled roll baler A when removing the formed bale B from the bale chamber 2 thereof. The operation of taking out the formed bale B from the bale chamber 2 mounted on the vehicle body a of the self-propelled roll baler A outside the machine is performed by a heavy bale B.
Can be performed without the need for manual lifting operation by effectively utilizing the mechanism provided in the roll baler A, and the bale B can be discharged to the side of the vehicle body a. It is another object of the present invention to provide a new means for driving the vehicle body a immediately after the release of the bale B so that the next bale forming operation can be performed.

[0013]

According to the present invention, as a means for achieving this object, a pickup device 1 is provided at the front end side of a vehicle body a that is running in a self-propelled manner. In a self-propelled roll baler A in which a bale chamber 2 containing a bale forming device 7 is mounted, a bale chamber 2 is a lower chamber 20 fixedly mounted on a vehicle body a.
