Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a roll baler, and can be used as a roll baler for harvesting grass.

Prior Art and Problems to be Solved by the Invention The conventional bale chamber of a roll baler was composed of a single chamber. There is also an example of Japanese Utility Model Application No. 58-185044, in which small grass rolls rolled in a preliminary bale room are sequentially sent to the main bale room to make large grass rolls. After the pasture rolls were made, the time until they were tied with string or the like and discharged outside the bale room was a waste of time as the next roll could not be made.

Means for Solving the Problems This invention includes a pickup device (2) that picks up grass (1), and an upper and lower part of the rear side of the pickup device (2), which rolls up the fed grass (1) into a roll. Upper veil chamber (3
) and the lower bale chamber (4), each of these bale chambers (
3) A feeding device (5) that mutually switches the feeding directions (A) and (B) by detecting the rolled grass (1) in (4).
) is provided.

Functions and effects of the invention While the roll baler is progressing, its pick-up device 1
When (2) picks up the grass (1) that is on the ground after being cut, the feeding device (5) located in the supply direction (A) sends the grass (1) to the upper bale chamber (3). enter,
The upper bale chamber (3) rolls up the grass (1) one after another into a roll, and inside the room, the roll of grass (1) is gradually enlarged and further tightened to an appropriate hardness. (1) When the roll is detected, when the feeding device (5) switches the grass (1) feeding direction to (b), the lower bale chamber (4) starts to roll in the grass (1). Immediately after this supply switching, the upper bale chamber (3) performs the bundling and release of the grass (1) rolls, and enters a semi-IiI state to receive the next supply of grass (1). In this way, each bale chamber (3) and (4
) and grass (1) rolls can be made alternately. Therefore, both the pick-up device (2) and the feeding device (5) continuously pick up and feed the grass (1), and the roll baler can perform continuous work without stopping.

) to form.

The feeding device (5) is a conveyor with a bar (15) and a chain (11) similar to the endless chain (11) forming the outer periphery of the bale chambers (3) and (4). The chino (11) is stretched between the front and rear shafts (30 and (37), and the switching rotation shaft (30) serves as the mounting fulcrum for the pickup device (2).
is located on the front side and is configured to be able to be switched around this shaft (30) by a hydraulic cylinder (35).
Veil part (7) Shaft (
34) Arms (3B) that support (37) on the left and right sides
(38), and the rear shaft (37) passes through the chamber wall (10) to provide an elongated hole (38) for switching.

Upper and lower bale chambers (3) (4) and feeding equipment! The interlocking structure of each endless chino (11) with (5) is such that the interlocking shaft (40) that connects to the power take-off shaft of the tractor and interlocks the roll baler is mounted on the support (4I) erected on the frame (9). A power intake shaft (
43), and is interlocked with each part by a belt from a pulley (45) provided on an interlocking shaft (44) inside this interlocking case (42). First, the belt (48) is passed from the pulley (45) of the interlocking case (42) to the pulley (47) provided on the sprocket shaft (4e) located at the upper lip of the receiving port (12) of the upper veil chamber (3). After winding and interlocking, endless chain 7 (11) and belt (49) (50) (51) (52)
By sequential interlocking, each endless chain (11) is configured to be interlocked in relation to each other.

In addition, in the upper bail chamber (3), the interlocking mechanism that is interlocked intermittently by turning on and off the tension clutch (53) (53) is a push-out disc ( 21) and the cylindrical shaft (23) and the string (1
8) and the lower bale chamber (18).
In 4), this tension clutch (53), which is the cylindrical shaft (23) of the extrusion disk (21) and the string (18) and the delivery roll (19), are interlocked by a bell (513).
) and (53), the important thing is 1, clutch arm (57)
The other end of the loft (58) (58) connected to (57) is connected to the arm (38) and (BO) of the feeding device (5), and the feeding direction (a) ( Due to the switching action (b), when one is a person, the other is configured to be switched off.

The pressure detection device for the grass (1) roll, which automatically switches the feeding device (5), is mounted on an L-shaped arm (81) along the outer surface of the left and right chamber walls (10) of the upper and lower bale chambers (3) and (4). ) (
A fulcrum (62) is provided at the corner of the chamber wall (10) so as to be able to shift, and a roll (63) extending between the left and right chamber walls (10) is provided at the tip of the longitudinal arm (61). ) is pivotally supported for driven rotation, and the chamber wall (lO) is provided with an elongated length so as to be swingable, and a tension spring (84) (84) is engaged with the other end of the arm (81) (81). Then, fix the other end of the spring (84) (84) to the chamber wall (1o), and when there is no grass (1) in each bale chamber (3) (4),
The roll (63) comes into contact with the endless chain (11) from inside the winding area and presses it into position with the elastic force of the spring (64), and the grass (1) is tightly wound and the endless chain is removed. The tension in the entire chain increases due to the pressure pushing toward the chain, and the roll (63) is pressed against the chain, and when it shifts about the fulcrum (62), the L-shaped arm (61) is placed in the position where it should come into contact with the micro Seven actuators of switches (135) (111B) are positioned and provided, and by turning on and off these micro switches (85) (8111), the solenoid valve (87) of the hydraulic circuit is operated and the hydraulic cylinder (35) is expanded and contracted. configured to switch (1
38) is an oil tank, (119) is an oil pump, and (70) is a battery.

When a roll baler towed by a tractor moves through a pasture (1) field where cut grass (1) is scattered on the soil surface, the finger (3) of the pick-up device (2)
1) scoops up the grass (1) and continuously transfers the grass (1) from the raking port (3B) to the feeding device (5) oriented in the supply direction (A) to the upper bale chamber (3). do. The bar (15) of the rotating endless chino (11) of the feeding device (5) moves the grass (
1) into the upper bale chamber (3) continuously.
) is fed by the bar (15) of the endless chain (11) on the outer periphery, gradually becoming a larger roll, and eventually becoming a hard roll that presses the sensor roll (63) outward and the arm (61) When the 7 actuator of the micro switch (65) is contacted, the switch (65) is turned on and the solenoid valve is switched to the hydraulic cylinder linear port, and the feeding device (5)
rotates at a constant speed in the supply direction (b) to the lower bale chamber (4). At the end of the switching operation, the tension clutch (53) on the upper bale chamber (3) side is activated by pulling the loft (58).
) is turned on, belts (50 and (55) are interlocked,
The extrusion action of the extrusion disk (21) and the delivery action of the string (18) and delivery roll (18) are performed. On the other hand, grass (1)
is continuously fed into the lower bale chamber, and when the roll of grass (1) hardens, the arm of the lower sensor roll (83)
61), the microswitch (8B) is set to O.
N, the solenoid valve (67) switches to the port for extending the hydraulic cylinder (35), and the feeding device (5) moves into the upper bale chamber (
At the same time as switching to the upper bale chamber (3) side, the actions of the extrusion disk (21), string (18) and feed roll (19) on the upper bale chamber (3) side stop, and on the other hand, on the lower bale chamber (4) side, The extrusion action of the disk (21) and the string (18) delivery roll (1
9) begins to work. In this way, the feeding device (5) is automatically detected by the sensor micro switch (65) (H).
) It is convenient to switch the transfer direction (a) and (b).

In addition, it is convenient to extrude the pasture (1) roll by the extrusion disk (21) and to feed out the string (18) at the same time because it can be further automated.
