Description

[Detailed description of the invention] (Field of industrial application) This invention is a pick-up device for picking up collected materials such as grass that has been cut down and left on the ground, and waste straw that has been threshed and released into the field. Regarding equipment.

(Prior art) As a pick-up device for a ground debris collector,
The structure described in Japanese Utility Model Application No. 60-162427 filed by the present applicant is publicly known.

This known structure has a pick-up device located at the front of the aircraft that picks up objects scattered on the ground.
The height can be adjusted up and down according to the unevenness of the ground by turning the adjustment handle provided on the control unit at the rear of the aircraft, allowing the pick-up device to approach the ground and effectively pick up collected items. That's what I do.

(Problem to be Solved by the Invention) When collecting items with the above-mentioned collection machine, the height of the pick-up device from the ground is adjusted by rotating the adjustment handle while the machine is running. When the aircraft is turning or just traveling without performing collection work, the pick-up device must be kept high off the ground and the adjustment handle must be turned many times, resulting in poor workability. Unable to work quickly.

Therefore, the present invention attempts to make it possible to finely adjust the pick-up device up and down and to move it up and down by a large amount with a simple configuration.

(Means for solving problems) Therefore, the present invention is constructed as follows.

That is, a pick-up device 2 provided at the front part of the vehicle chassis 1 so as to be movable up and down, and a mounting member 24 screwed onto a threaded shaft 23 of an adjustment handle 4 provided on the operation side 3 are connected to an inner wire 5 which is inserted through the outer wire 5. Connect with wire 6 and connect with outer wire 5
A mounting member 26 on the control operation side 3 is provided so as to be movable along the inner wire 6, and an operating lever 7 for moving this mounting member 26 is provided, and the pick-up device 2 can be finely adjusted up and down by rotating the adjustment handle 4. By moving the mounting member 26 of the operating lever 7, the lever 7 can be moved vertically to a large extent.

(Function of the invention) When finely adjusting the pick-up device 2 at the front of the chassis 1 up and down according to the unevenness of the ground while the chassis 1 is running, the control operation side 3 connected to the pick-up device 2 with an inner wire 6 is used. This can be done by rotating the adjustment handle 4 on the side.
When the operating lever 7 is operated to move the attachment member 26 of the outer wire 5 toward the pick-up device 2, the inner wire 6 is pulled and the pick-up device 2 is pulled up. When the operating lever 7 is returned to its original position, the attachment member 6 of the outer wire 5 returns to its original position, and the pickup device 2 reaches the height set by the adjustment handle 4.

(Effect of the invention) As described above, fine vertical adjustment and large vertical movement of the pick-up device 2 provided at the front part of the vehicle chassis 1 can be achieved by connecting the pick-up device 2 with a pair of outer wires 5 and inner wires 6. This can be done quickly by operating the adjustment handle 4 and the operation lever 7 on the control side 3, and after moving the pick-up device 2 up and down by a large amount with the operation lever 7, further finer vertical adjustments can be made by operating the adjustment handle 4. can.

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

At the front of the chassis 1, which is equipped with a traveling device consisting of a crawler 8, there is a fixed machine frame 9 and a movable machine frame 1, which are equipped with a bale mechanism for packing collected items in a roll shape.
At the rear of the chassis 1, there is provided a driving frame 11 in which a prime mover is installed.

The movable machine frame 10 has a pivot 12 relative to the fixed machine frame 9.
When the handle 13 is rotated upward, the entire body is rotated upward to open the interior, and the rolled bale can be taken out of the machine.

At the lower front of the fixed machine frame 9, a plurality of scraping rods 15 are protruded from the cylindrical body 14 at regular intervals in the lateral direction.
The pick-up device 2 rotates forward and upward as the cylindrical body 14 rotates and picks up collected items on the ground.
It is provided to be movable up and down on a pivot 16.

On the upper part of the driving frame 11, there are operating tools such as a side clutch lever 17 that changes the running direction left and right, a driving clutch lever 18 that disconnects power transmission to the traveling device, etc., and the left side of the driving frame 11. includes a working clutch lever 1 for intermittent driving of the bail mechanism inside the fixed machine frame 9 and the movable machine frame 10;
9 and an operating lever 7 for raising the pick-up device 2 significantly upward, and an adjustment handle 4 for finely adjusting the up and down of the pick-up device 2 is provided on the rear side of the driving frame 11.

The interlocking state of the operation lever 7 and the adjustment handle 4 with the pickup device 2 is as shown in FIG.

A side frame 20 of the pick-up device 2 and an arm 21 pivotally supported on a fixed machine frame 9 are connected by a rod 22, so that the entire pick-up device 2 can be rotated up and down by rotation of the arm 21.

The pivot shaft 23 of the adjustment handle 4 is provided with a male thread, and the inner wire attachment member 24 screwed into the male thread is connected to the arm 21 by the inner wire 6. The pick-up device 2 is made to move up and down.

The outer wire 5 through which the inner wire 6 is inserted is provided between a mounting member 25 protruding from the fixed machine frame 9 and an outer wire mounting member 26 provided on the drive frame 11 side.

The outer wire attachment member 26 is slidably fitted onto a shaft 30 provided parallel to the pivot shaft 23 of the adjustment handle 4, and the outer wire attachment member 26 and the operating lever 7 are separate from the above. When the operating lever 7 is rotated, the outer wire attachment member 26 slides on the shaft 30 and the outer wire 5 is bent. This bending of the outer wire 5 causes the inner wire 6 to be pulled by the arm 21 connected to the pick-up device 2.
As a result, the pick-up device 2 is raised.

When the operating lever 7 is returned to its original position, the outer wire 6 is no longer bent and the pick-up device 2 is lowered to its original position.
