Description

Description: TECHNICAL FIELD The present invention relates to a continuous method for directly winding a film of a bare roll bale feed formed by a roll baler on a bale wrapper, and an apparatus for carrying out the method.

[Prior Art] A well-known roll baler picks up grass, rice straw, straw, etc. from the ground to form a cylindrical veil, and releases the formed bare veil to the back ground again. The well-known bale wrapper for wrapping is to wrap and wrap a film while rolling a bare bale on a table, and both of them are usually handled as independent agricultural working machines.

In the field, forages such as grass, rice straw, and straw are formed into roll balers by roll balers, and the formed roll balers are left as they are in the field or transported to the roll balers, and then in the fields or roll balers. The roll bale was film-wrapped by the bale wrapper. Poor feed quality was inevitable when bare roll bale feed met the rain before being film wrapped.

[Problems to be Solved by the Invention] In order to wrap the roll bales released to the ground by the roll baler as quickly as possible, the roll baler is pulled by the roll baler so that the roll baler rolls on the ground rather than on the belt. I tried to wrap the roll bale released on the ground immediately,
It turned out that the film was easy to break when it was rolled on the ground and wrapped.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a method and an apparatus for immediately wrapping a roll bale formed by a roll baler on a belt in a table without lowering it to the ground. Especially.

[Means for Solving the Problems] Means to be adopted by the present invention for achieving the above-mentioned object are as follows. A well-known bale wrapper is connected to a well-known roll bale via a connecting means so as to be able to be pulled, and a transfer provided in the connecting means. The roll bale discharged by the roll baler is transferred to the bale wrapper via the means, and the operation of the roll baler and the wrapper is associated with each other via the interlocking control means as required. The connecting means has a front end connected to the roll baler so as to be swingable right and left, and a rear end fixedly connected to the bale wrapper.

[Operation] A known roll baler collects feed to form a roll bale, and when the bale reaches a predetermined size, the bare bale is released backward to suspend the operation. The released bare bales are received by the transfer means on the connecting means. When the roll baler discharges the bare bale, the manual operation or the interlocking control means causes the bale wrapper to discharge the wrapped roll bale on its table to the ground, and the transfer means transfers the received roll bale to the lift arm of the wrapper or Carry directly to the belt in the table. When the roll bale rests on the lift arm or table of the wrapper, either manually or through interlocking control means, the roll baler and wrapper resume operation. If the known bale wrapper has a lift arm, the lift arm is rotated to transfer the bare bale on the lift arm onto the belt in the table before wrapping. The bale wrapper cuts the film when wrapping is complete and suspends operation while holding the edge of the film. In this way, feeds such as grass, rice straw, and straw in the field are sequentially collected and formed into a roll-shaped bare bale, and then continuously released as a film-wrapped wrap bale.

[Example] The present invention will be described based on an example shown in the drawings.

As shown in FIG. 1, a well-known bale wrapper 30 is also pulled and connected to the well-known roll baler 10 through a connecting means.

A hydraulically driven transfer conveyor may be provided instead of the transfer plate to carry the bare bales received from the roll baler to the lift arm.

The back cover 14 of the roll baler 10 is attached to the frame 11 via pins 13, and a hydraulic cylinder 16 is interposed between the frame 11 and the back cover 14 to open and close the back cover 14 up and down.

A fixed shaft 35 is attached to a carriage 31 of the bale wrapper 30, and a hollow rotary shaft 36 is fitted on the fixed shaft. A swing arm 37 extending in the diametrical direction is rotatably attached to the hollow rotary shaft. A film support device 38 is provided at both ends of the revolving arm 37, and a roll film 39 is rotatably attached to the film support device. Although not shown, the carriage 31 is provided with a hydraulic device for turning the turning arm 37.

The table 40 is fixed to the upper end of the fixed shaft 35, a bracket is provided on the table, and the driving and driven rolls 42 and 43 are borne by the bracket. A hydraulic cylinder for rotating the bracket around the drive roll 42 is provided. A belt 45 is hung on the driving and driven rolls 42 and 43. Film gripping and cutting devices 47 are attached to both sides of the table 40. Although not shown, a rotation transmission mechanism for rotating the drive roll 42 from the hollow rotary shaft 36 is provided.

Next, the bale formation and the continuous film wrap of the present invention will be described. As shown in FIG. 1, the roll baler 10
When the bare bale 60 having a predetermined size is formed, the operator stops the tractor 50 and manually or automatically operates the control device of the roll baler 10 and the bale wrapper 30 provided in the driver's seat of the tractor. The first step is the release of bare bales from the roll baler 10 and the discharge of wrap bales from the bale wrapper 30. The hydraulic cylinder 16 is extended to open the back cover 14 and discharge the bare bales 60 from the roll baler 10 onto the transfer plate 23, as indicated by the dashed line. When the bare bale 60 is placed on the transfer plate 23, the spring 25 supporting the rear end portion of the transfer plate 23 expands due to its weight, so that the transfer plate 23 inclines rearward and downward. as a result,
The bare bale 60 rolls on the transfer plate 23 and fits into the lift arm 33. When this is detected by the operator or the sensor, the manual or automatic operation of the second step is started.

As shown in FIG. 2, the hydraulic cylinder 16 of the roll baler 10

Put on. After that, the hydraulic cylinder 34 holds the lift arm 33 at a position slightly higher than the original position. When the worker or the sensor detects that the bare bale 60 is on the belt 45, the manual or automatic operation of the third step is started.

As shown in FIGS. 3 and 4, the tractor 50 is started, feed collection and veil formation in the field by the roll baler 10 are restarted, and the belt 45 of the baler wrapper 30 is rotated to roll the bare bales 60. , Rotate the swivel arm 37,
A bare veil 60 is wrapped with a film 49 drawn from a roll film 39 mounted on the film support device 38. At this time, the table may be rotated in the direction opposite to the turning arm.

As shown in FIG. 5, the bale wrapper 30 wraps one bale faster than the roll baler 10 forms one bare bale. When the wrapping is finished, the wrapper 30 cuts the film by the film support cutting device 47, holds the end of the film 49 pulled out from the roll film 39, and temporarily stops the operation.

As shown in FIG. 6, when the roll baler 10 releases the bare bale having a predetermined size in the first step, the hydraulic cylinder bracket 41 is rotated around the drive roll 42, so that the lap bale 61 is a bale wrapper. It is discharged to the ground behind 30 and at the same time, the hydraulic cylinder 34 contracts and the front end of the lift arm 33 contacts the ground.

As shown in FIG. 7, there is no lift arm,
In the case where 37 is the bale wrapper 30 mounted on the column 48 erected on the carriage 31, a hydraulically driven belt conveyor 26 is mounted on the connecting frame 20, and the bare bale 60 discharged from the roll baler 10 by the belt conveyor is baled. Rapper
It can be directly sent to the belt 45 in the table 40 of 30.

ADVANTAGES OF THE INVENTION According to the present invention, a bare roll bale formed by a roll baler is automatically transferred to a subsequent bale wrapper, and the bale wrapper is transferred while the roll baler is forming a next roll bale. The complete roll wrap film wrap is completed, so compared to the work of forming a bare roll bale with a conventional independent bale wrapper and then film wrapping a bare roll bale with a similar independent bale wrapper. The work time is reduced by the time required for wrapping, the labor of placing a bare roll bale on the bale wrapper is omitted, and the work efficiency is greatly improved. Further, since the naked roll veils are film-wrapped without waiting time, there is also a special effect that there is no possibility that the naked roll veils are exposed to wind and rain and the quality of feed is deteriorated.
