The bucket 1 rotates by the expansion and contraction of the bucket cylinder 34 via the bell crank 33, whereby the direction of the bucket 1 moves up and down (tilt and dump).
[0013]
As shown in FIG. 2 to FIG. 8, the above-described bucket 1 for processing compost or the like includes a bucket body 2, beater arms 3 </ b> R and 3 </ b> L rotatably provided on both left and right ends of an upper rear surface of the bucket body 2. , 3L, and a plurality of stirring blades 5 provided on the outer periphery of the rotating shaft 4 so as to be rotatably supported by them. The bucket body 2 is provided so as to close the left and right ends of the main structural member 2D including the bottom plate portion 2a, the upper plate portion 2b, and the back plate portion 2c having a continuous curved shape. It consists of a right side plate member 2E and a left side plate member 2F. The bucket body 2 has an opening A in the front.
[0014]
The beater arms 3R and 3L have a substantially L-shape, and their base ends are rotatably supported by brackets 6 provided on the left and right ends of the back surface of the upper plate 2b of the bucket body 2, respectively. In the vicinity of the minute, both are connected by the connecting member 7 and rotate integrally. The beater arms 3R and 3L are rotated by a hydraulic cylinder 8 having one end attached to the bucket body 2. The other end of the hydraulic cylinder 8 is rotatably supported at an intermediate portion of a link 9 which is rotatably supported by the bracket 6 at one end, and a rotatably provided link 10 is provided at the other end of the link 9. The beater arms 3R and 3L are connected to each other via. Thereby, the rotating shaft 4 provided at the distal ends of the beater arms 3R, 3L can be moved from the upper position shown in FIGS. 5 to 7 to the deep position inside the bucket body 2 shown in FIGS. Further, a hydraulic motor 11 is provided at one end of the beater arm 3L, and a rotational force is transmitted to a rotating shaft 4 described later by a chain 12 attached to an outer surface of the beater arm 3L. The chain 12 is covered by a chain cover 13 provided on the beater arm 3L, and the hydraulic motor 11 and the rotating shaft 4 have a transmission mechanism using a chain and a sprocket. Note that the distance between the beater arm 3L including the transmission mechanism such as the chain 12 and the beater arm 3R is set smaller than the distance between the left and right side plate members 2E and 2F of the bucket body 2, and in combination with the above-described configuration, the rotation shaft 4 enters the bucket body 2, the beater arm 3 </ b> L and the beater arm 3 </ b> R equipped with the transmission mechanism such as the chain 12 also enter the bucket body 2, and the agitating blades 5 move inward (back plate) inside the bucket body 2. (In the vicinity of the section 2c).
[0015]
The rotating shaft 4 is rotatably provided at the distal ends of the beater arms 3R, 3L via bearings, and a plurality of stirring blades 5 are provided on the outer peripheral surface thereof. The stirring blade 5 has a fan shape, and a plurality of notches are formed at the tip thereof. Then, in a state where the rotating shaft 4 is moved to the back inside the bucket body 2, the stirring blade 5 is accommodated without protruding from the opening A.
[0016]
In addition, a scraper 14 is provided on each of the beater arms 3R and 3L from the tip to the middle. The scraper 14 prevents the entry of the beater arms 3R and 3L from being prevented by the stored compost or the like when the beater arms 3R and 3L enter the bucket body 2. That is, when the beater arms 3R and 3L enter, the contents such as the compost housed in the bucket body 2 are transferred to the beater arms 3R and 3L and the beater arm 3L. The compost or the like is sandwiched between the rear portion 2c and the compost and the like, which serves as a resistance to the further movement of the beater arms 3R and 3L toward the back. In order to prevent this, the beater arms 3R and 3L are provided with a scraper 14 made of a plate member having an edge portion 14a covering the transmission mechanism and the bearing from the tip to the middle. As shown in FIG. 8, the scraper 14 extends diagonally from the lower surfaces 3Ra (3La) (only one of which is shown) of the beater arms 3R, 3L toward the right side plate member 2E of the bucket body 2 so as to have a tapered surface 14b. The edge portion 14a is formed so as to approach the inside of the right side plate member 2E, and the scraper 14 passes through the bearing of the rotating shaft 4 from a position protruding from the tip of the beater arm 3R, 3L, and passes through the bearing of the beater arm 3R, 3L. It is provided over the middle part. The beater arm 3L has the same configuration.
[0017]
As a result, the scraper 14 comes into contact with the items accommodated in the bucket body 2 prior to the bearings of the beater arms 3R, 3L and the rotating shaft 4 with the movement of the beater arms 3R, 3L into the bucket body 2, Since the stored object is pushed down along the tapered surface 14b toward the central portion of the bucket body 2 and sunk, the entry resistance of the beater arms 3R and 3L can be reduced. In addition, since the contents do not directly contact the bearing of the rotating shaft 4, damage can be prevented.
[0018]
The beaters including the above-described beater arms 3R and 3L, the rotating shaft 4, the stirring blade 5, the hydraulic cylinders for driving them, the hydraulic motor 11, and the like (drive mechanism) are referred to as beaters.
[0019]
Next, the operation by the composting bucket of the present invention will be described.
[0020]
First, the wheel loader 30 is moved to a place where an object to be treated such as compost is present. Then, the boom cylinders 32 lower the booms 31R and 31L, extend and retract the bucket cylinder 34, and lower the bucket body 2 toward the ground, so that the bottom plate 2a of the bucket body 2 is substantially horizontal with the ground. Let it. (See FIG. 1.) Then, the hydraulic cylinder 8 is contracted to move the beater arms 3R, 3L to a position above the bucket body 2, and the rotary shaft 4 is retracted from the front of the opening A of the bucket body 2. Then, the wheel loader 30 is moved toward the pile of compost or the like, and the compost or the like is taken into the bucket body 2. Then, the bucket body 2 is raised by the boom cylinder 32. Next, the hydraulic motor 11 is driven to rotate, and the rotating shaft 4 is rotated. Then, the hydraulic cylinder 8 is extended to lower the beater arms 3 </ b> R and 3 </ b> L, and the stirring blade 5 rotating together with the rotating shaft 4 is moved deep inside the bucket body 2. During this movement, the beater arms 3R, 3L are prevented from entering by the compost loaded inside the bucket body 2, but the scraper 14 preceding the beater arms 3R, 3L first sinks into the compost, and removes the compost. Can be pushed away toward the center of the arm, so that the entry resistance is reduced, and the beater arms 3R and 3L move smoothly. With this movement, the compost taken into the bucket body 2 is stirred, cut, and crushed by the rotation of the stirring blade 5. As a result, the compost is exposed to the air and cut back. Further, by the rotation of the stirring blade 5, the compost in the bucket main body 2 can jump out from the opening A of the bucket main body 2 and can be sprayed without forming a lump. Further, when the compost is taken into the bucket body 2, an arbitrary work place can be set by moving the wheel loader 30 to the spraying place and the stirring place, and the beater arms 3R and 3L are retracted to the upper position. If used, the original use of the wheel loader 30 as a normal transport and loading machine becomes possible.
[0021]
In the present embodiment, the structure is simplified because the pushing device is not provided inside the bucket, and the capacity of the bucket is not reduced. Therefore, it can be used as a normal loading machine. In addition, loading, transporting, stirring, and spraying can be performed by a single device, and the use of the device is expanded, and the machine operation rate and workability are improved as compared with a dedicated machine.
[0022]
In the above description, an example in which compost is loaded has been described. However, wood chips, sawdust, sand, and the like can also be used, and the stirring blade 5 cuts the chips more when loading the wood chips. When loading sawdust or sand, it is possible to crush even a lump of material to some extent. As another example of use, cement, water, sand and the like are put in the bucket body, and they are mixed by rotation of the stirring blade 5 to be used as a concrete production and transporter.
[0023]
Further, the shape and material of the stirring blade 5 can be changed to various ones according to the contents to be taken into the bucket body 2 and may be configured to be detachable.
[0024]
Further, the shape (outer diameter) of the stirring blade 5 provided on the rotating shaft 4 can be set to a size close to the diameter of the back plate portion 2c of the bucket body 2, whereby the stirring blade 5 is 2, the gap between the bucket body 2 and the stirring blade 5 is reduced, and the stirring efficiency can be further improved.
[0025]
The hydraulic cylinder 8 and the hydraulic motor 11 can be configured to be driven by a hydraulic source from the wheel loader 30.
[0026]
The self-propelled vehicle is not limited to the wheel loader, but may be a hydraulic shovel having a crawler-type traveling body.
[0027]
【The invention's effect】
As described above, the compost processing bucket and the compost processing machine of the present invention have a simple structure, do not reduce the bucket capacity, can be used widely, and can improve workability.
