Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tip attachment bucket for a front loader.

(Prior Art) The tip attachment bucket of the front loader is used for agricultural work such as spreading fertilizer, and for this reason, the bucket can be dumped in the front and back direction.

(Problems to be Solved by the Invention) As described above, since the conventional bucket cart performs the above-mentioned spreading of fertilizer only by dumping in the front and back direction, there is a problem that the efficiency of these operations is poor.

SUMMARY OF THE INVENTION An object of the present invention is to provide a front-loader attachment bucket that has a simple structure and can efficiently perform operations such as spreading the fertilizer.

(Structure of the Invention) The tip attachment bucket for a front loader according to the present invention includes a bucket base that constitutes the rear part of the bucket, and a movable bucket part that is pivotally connected to the upper end of the bucket base and constitutes the front part of the bucket. A bucket main body that can be opened and closed, a cylinder device having one end attached to the bucket base side and the other end attached to the bucket movable part side to open the bucket main body while adjusting the opening degree, a width direction of the bucket main body at least one cutter having a rotating shaft extending from the bucket and rotatably attached to both sides of the bucket movable part, and a blade provided on the rotating shaft for processing the load on the bucket main body;
The apparatus is characterized in that it comprises a cutter drive means disposed on the base side of the bucket, and a transmission means for operatively connecting the cutter drive means to the cutter. Note that the transmission means preferably includes a universal slide joint.

(Effects of the Invention) As described above, in the front loader tip attachment bucket of the present invention, the bucket main body is composed of a bucket base and a bucket movable part that can be pivotally connected to the bucket base. The bottom of the bucket can be opened at the desired opening angle, making it easier to control the amount of fertilizer sprayed, for example, and the cutter provided inside the bucket body allows for efficient spraying of compost, etc. while crushing it. .

(Embodiment) Hereinafter, a tip attachment bucket for a front loader according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

In the figure, reference numeral 1 indicates a tractor, and a front loader 10 is attached to this tractor 1. The tractor 1 has a vehicle body 2, and a driver's seat 3 is provided approximately in the center of the vehicle body 2. At the side of the vehicle body 2 slightly in front of the driver's seat 3, that is, at a position where the driver can operate from the driver's seat, there is a deformed pin 4 extending horizontally outward in the lateral direction.
is rotatably supported by a bearing 5 about its central axis. On both sides of the front end of the vehicle body 2,
A shaft 7 is secured by a mounting member 6 and extends laterally outward from the side of the vehicle body 2. In the figure, the reference numeral 8 indicates an exhaust pipe for exhausting air from an engine (not shown).

On the other hand, the front loader 10 has a frame 11 that extends substantially vertically in a normal state, and a lift arm 1 is provided in the upper part of the frame 11.
2 is pivotally mounted at its base. This lift arm 12 extends long in front of the tractor 1, and a cargo handling section, that is, a tip attachment bucket 30 is attached to the tip of the lift arm 12. A bracket 14 is provided at the intermediate portion of the lift arm 12, and a double-acting hydraulic cylinder device, that is, a lift cylinder 15, which has one end rotatably attached to the lower end of the frame 11, is mounted on the bracket 14. The other end is rotatably attached. Therefore, by extending and contracting the lift cylinder 15, the lift arm 12 can be rotated up and down.

The bracket 14 of the lift arm 12 includes:
An upwardly extending link 16 is pivotally mounted and is connected to the bucket cart 30 by a link rod 17. A double-acting hydraulic cylinder device, ie, a dump cylinder 18, whose one end is pivotally connected to the frame 11, is further pivotally connected to the link 16 at the other end.
As the dump cylinder 18 expands and contracts, the bucket 30 rotates or dumps back and forth, that is, clockwise or counterclockwise in the figure. This rotation allows the excavation angle of the bucket to be changed, etc.

The bucket bag of the present invention can be divided into front and rear parts. The configuration will be explained below with reference to FIG. 2 and subsequent figures.

The bucket bag 30 has a bag bag main body 33 that can be opened and closed in the front and back direction, and includes a bag bag base 31 that constitutes the rear part of the bucket bag, and a bucket movable part 32 that is pivotally connected to the upper end of the bag bag base 31 and that configures the front part of the bucket bag. are doing. This bucket body 3
3, one end is pivotally connected to the bucket base 31,
The other end is provided with a hydraulic cylinder device 34 pivotally connected to the bucket movable portion 32. This hydraulic cylinder device 34 is extended to the bucket 30.
The bucket 30 is closed by opening and contracting, and the degree of expansion causes the bucket 3 to close.
The opening degree of 0 can be adjusted.

The bucket main body 33 further includes a bucket movable part 3 extending in the width direction of the bucket main body 33.
Rotating shaft 35 rotatably attached to both sides of 2
It is equipped with This rotary shaft 35 is provided with a cutter blade 36 for crushing hardened compost etc. loaded in the bucket main body 33. As shown in FIG. 3, for example, this cutter blade 36 has a spiral direction that changes at the center of the rotating shaft 35, and can crush compost while transferring it to the center of the bucket. A screw-like type 36a, a three-blade type 36b as shown in FIG. 4, and a four-blade type 36c as shown in FIG.
It can be done. These shall be appropriately selected depending on the type of load. Further, from the viewpoint of stirring, it is desirable that the rotating shaft 35 be an eccentric shaft. Note that the rotary shaft 35 is driven by a hydraulic motor via a universal slide joint (not shown), so the bucket 3
Operation is possible even when 0 is open.

In the above-mentioned embodiments, a single rotating shaft has been described, but two rotating shafts 40 and 41 may be used as shown in FIG. At this time, rollers 42 and 43 as shown in FIG. 6 may be used instead of the cutter blades to crush the compost or the like. In addition, at this time, the two rotating shafts 4
It is assumed that the rotation directions of 0 and 41 are set so that the upper parts rotate toward each other as shown in FIG.

Furthermore, when using two rotating shafts 40 and 41, as shown in FIG.
A plurality of pairs of bearings 50a, 50b, 51 are mounted on the side wall of the
a, 51b, 52a, 52b, 53a, 53b,
It is desirable that the two rotary shafts 40, 41 are provided so that the distance between the two rotating shafts 40, 41 can be set to a distance that is suitable for the load.
