Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compost turning bucket and a work vehicle for promoting composting by stirring materials such as cow dung and bedding.

[0002]

2. Description of the Related Art Conventionally, in the treatment of livestock excrement, a material such as straw is added to the excrement to be deposited and fermented to produce compost. In this case, in order to promptly compost the material, it is necessary to increase the air permeability in the sediment and promote the action of microorganisms living in the material. Therefore, we loosen clumps of sediment to increase air permeability,
The work of turning back to help the bacterial fermentation is performed.

[0003] In this reversing work, after sediment (compost) is scooped by a bucket attached to a wheel loader or the like, the bucket is vibrated little by little to drop the compost little by little and loosen the compost that has become a lump. In this way, the air permeability of the compost was increased, and the compost was in a state in which it was easy to ferment.

[0004]

However, in the above-mentioned conventional turning method, since the compost is simply dropped while the bucket is vibrated little by little, the sediment cannot be sufficiently loosened, and the composting is promoted. It was not enough. Further, the work while the bucket is vibrated little by little deteriorates the operability of the operator and the durability of the wheel loader body.

An object of the present invention is to provide a compost-turning bucket and a work vehicle capable of efficiently performing a turning-over operation.

One end of a is rotatably supported via a bearing (not shown). The other end of the rotor rotation shaft 9a penetrates through the hole 19a on the left side of the bucket, protrudes into the chain case 21, and is rotatably supported via a bearing (not shown) mounted in the hole 19a. A hydraulic motor 28 is attached to the bracket 20 on the left side of the bucket, and an output shaft 28 a of the hydraulic motor 28 projects into the chain case 21. In the chain case 21, the rotor rotation shaft 9a and the motor output shaft 28a are connected by a chain 30 via a sprocket 29. Thereby, the rotation of the hydraulic motor 28 is transmitted to the rotor 9 and
The rotor 9 rotates at a speed and a direction corresponding to the rotation speed of the rotor 9. The direction R1 in FIG.
The direction is defined as the reverse direction of the motor 28.

FIG. 10 is a sectional view taken along line XX of FIG. As shown in FIGS. 7 and 10, spiral beams, that is, spiral beams 9b and 9c are provided on the outer peripheral surface of the rotor rotation shaft 9a from the left and right ends of the rotor to the center. The spiral beams 9b and 9c are attached to the shaft 9a at predetermined intervals (for example, 90 ° intervals) via columns 9e erected on the shaft 9a, and a saw-shaped cutter is formed on the outer peripheral surface of the spiral beams 9b and 9c. 9d are mounted at predetermined intervals (for example, at 120 ° intervals). The spiral directions of the spiral beams 9b and 9c are opposite to each other, and the rotor 9
When rotated in one direction, compost material is accumulated from the left and right ends of the rotor to the center.

FIG. 11 is a front view of the belt conveyors 7 and 8 installed at the rear of the bucket body 3 (the bucket body 3 and the rotor 9 are not shown). As shown in FIGS. 8, 9, and 11, the right end of the belt conveyor 7 and the left end of the belt conveyor 8 are connected via a link member 31. A link member 32 is further attached to the left end of the belt conveyor 8, and a rod-side end of a hydraulic cylinder 33 is rotatably connected to the link member 32. Hydraulic cylinder 33
Is rotatably connected to a bracket 34 (see FIG. 4) provided on the bucket body 3. The rotating shaft 7a at the left end of the belt conveyor 7 is a support 25F, 2
The left and right rotation shafts 8a of the belt conveyor 8 are rotatably supported by columns 25F and 25R.

The rotating shaft 7 at the right end of the belt conveyors 7, 8
Hydraulic motors 36 and 37 are attached to b and 8b, respectively, and the belt conveyors 7 and 8 are driven by rotation of the hydraulic motors 36 and 37, respectively. Guides 7g, 8g are supported from the frames 7f, 8f at the front and rear end portions of the belt conveyors 7, 8 (only the front side is shown) so as to sandwich the belt along the driving direction of the belt, and the belt conveyors are guided by the guides 7g, 8g. The load is prevented from falling around 7 and 8. Although not shown, the guides 7g and 8g are located outside the front-rear ends 18F and 18R of the opening 18 in the front-rear direction, respectively.
All the falling objects from 8 are placed on the belt conveyor 7. A slip stopper (not shown) is provided on the upper surface of the belt to move the load upward without slipping. The belt conveyors 7, 8 are driven in a direction to raise the load when the hydraulic motors 36, 37 rotate forward.

In FIG. 11, when the hydraulic cylinder 33 is retracted, as shown by a two-dot chain line, the belt conveyor 8 rotates about the rotation shaft 8a as a fulcrum, and becomes substantially vertical.
The belt conveyor 7 moves to the left while sliding on the rail member 35 while rotating via the link member 31, and is leveled as indicated by a two-dot chain line. As a result, the belt conveyors 7, 8 are housed substantially inside the width of the bucket body 3 in the left-right direction (storage position), and normal traveling of the wheel loader is facilitated. This posture is called a running posture. When the hydraulic cylinder 33 extends from the running posture, the belt conveyors 7 and 8 are both inclined as shown by a solid line (use position). This posture is called a working posture. In this case, the inclination angle of the belt conveyor 7 substantially matches the shape of the end faces 18F, 18R of the passage opening 18, and the inclination angle of the belt conveyor 8 is larger than the inclination angle of the belt conveyor 7.

Next, main operations of the compost turning bucket according to the present embodiment will be described. In the turning operation, first, the vehicle is moved to the end of the row of the compost material arranged in a plurality of rows as shown in FIG. Next, the booms 2R, 2L are operated by operating an operation lever (not shown).
Is raised or lowered, and the bucket BA is tilted or dumped, and the bucket BA is set in a posture horizontal to the ground as shown in FIGS. Then, belt conveyor 7,8
From the storage position (two-dot chain line in FIG. 11) to the use position (FIG. 11).
(Solid line). In this case, pressure oil from a hydraulic pump (not shown) is supplied to the bottom chamber of the hydraulic cylinder 33 by operating a switch or the like in the cab to extend the hydraulic cylinder 33. Accordingly, the belt conveyor 8 is inclined via the link member 32, and the belt conveyor 7 is inclined via the link member 31 with the inclination of the belt conveyor 8, so that the bucket BA is in the working posture.

When the bucket BA is set in the working posture, the hydraulic oil is supplied from the hydraulic pump to the hydraulic motor 28 by operating a switch or the like in the operator's cab to rotate the hydraulic motor 28 in the normal direction, and the rotor 9 is rotated as shown in FIG. It is driven in the R1 direction of 10. At the same time, the hydraulic oil from the hydraulic pump is
37, the hydraulic motors 36, 37 are rotated in the normal direction, and the belt conveyors 7, 8 are driven in a direction to raise the load.

Next, a forward / backward movement lever (not shown) in the cab is operated, and the accelerator pedal is depressed to advance the vehicle.
The front of the bucket BA is plunged into the deposited compost material.
Thus, the compost material is supplied to the cutter 9 of the rotating rotor 9.
While being crushed and agitated at d, the spiral beams 9b and 9c move the bucket toward the center of the bucket, are sent out to the back of the bucket via the passage 17, and fall onto the belt conveyor 7 from the opening 18. The compost material that has fallen is the belt conveyor 7
, And falls onto the belt conveyor 8 from the end of the belt conveyor 7. The compost material is further conveyed obliquely upward by the belt conveyor 8 and falls from the end of the belt conveyor 8 to the ground. As a result, FIG.
As indicated by the dotted line 2, the row of compost material moves to the side of the vehicle. When the vehicle moves to the end of the row, the vehicle is moved to another row, and the same operation is repeated thereafter. In the case where the lump of the compost material has digged into the rotor 9, the hydraulic motor 28 is rotated in the reverse direction to drive the rotor 9 in the R2 direction to remove the digging. In the case where the compost material is agitated by the rotor 9, a particularly large power is required. Therefore, in a state where the accelerator pedal is greatly depressed and the engine exhibits a high output, for example, only the running horsepower is reduced (not shown). By operating a pedal (so-called inching pedal), the vehicle travels at a very low speed, and most of the engine output is used for the driving force of the work implement.

When the reversing operation is completed, the rotation of the hydraulic motors 28, 36, 37 is stopped by operating the switches, and the driving of the rotor 9 and the belt conveyors 7, 8 is stopped.
Next, the pressure oil from the hydraulic pump is supplied to the rod chamber of the hydraulic cylinder 33 to cause the hydraulic cylinder 33 to retract. Thereby, the belt conveyor 8 rotates through the link member 32, the belt conveyor 8 becomes substantially vertical, the belt conveyor 7 rotates through the link member 31, and the belt conveyor 7 becomes substantially horizontal. , The bucket BA is in the running posture.

As described above, according to the present embodiment, the deposited compost material is sent out to the back surface of the bucket body via the passage 17 while being stirred by the rotor 9 provided on the front surface of the bucket body 3 in the width direction. The belt is conveyed to the side of the vehicle by belt conveyors 7 and 8. As a result, the air permeability of the compost material is increased, the composting is promoted, and the operability of the operator and the durability of the wheel loader main body are both improved as compared with a system in which the bucket main body is vibrated in small increments. In addition, spiral beams 9b and 9c are arranged around the outer peripheral surface of the rotor rotation shaft 9a via columns 9e,
Since the plurality of cutters 9d are arranged along the helical direction on the outer peripheral surfaces of the beams 9b and 9c, the outermost diameter of the rotor 9 becomes large, so that a large amount of compost material can be taken in and agitated. Further, since the helical directions of the left and right beams 9b and 9c are made opposite to each other, the compost material on the front surface of the bucket is collected on the left and right inner sides of the rotor 9 and sent out into the passage 17, and the scattering of the compost material in the left and right direction is reduced. Is prevented.

Further, the belt conveyors 7, 8 are provided so as to be rotatable, and the belt conveyors 7, 8 are moved during running.
The wheel loader can be run normally without any trouble because it is stored almost inside the horizontal width of the wheel loader. In this case, since the belt conveyors 7 and 8 are connected by the link member 31, the belt conveyor 8 rotates with the rotation of the belt conveyor 7.
Is rotated, the structure is simplified, and the position of the belt conveyor 8 with respect to the belt conveyor 7 is easily set. Further, since the upper surface of the belt of the belt conveyor 7 is located below the opening 18 at the rear end of the passage, the compost material can be placed on the belt conveyor 7 by the natural fall of the compost material from the opening 18. In addition, compost material that has been crushed and agitated along with the traveling of the wheel loader is loaded in a row on the side of the bucket, and the loaded compost material is sequentially turned back again. In addition, the rotational load of the rotor 9 is reduced, and a smooth turning operation can be performed.

The present invention is characterized in that the compost material is agitated by the rotor 9 provided on the front surface of the bucket and is transported to the side of the bucket by the belt conveyors 7, 8. The present invention is not limited to the above embodiment, and can be realized in various forms. For example, in the above-described embodiment, two belt conveyors 7 and 8 are provided on the left and right, but one may be provided for a large belt conveyor, and three or more belt conveyors may be provided for a small belt conveyor. Is also good. In the above embodiment, the spiral beam 9b,
The cutter 9d was attached to the peripheral surface of 9c,
The cutter 9d may be directly attached to the peripheral surface of the rotating shaft 9a or the column 9e. In this case, the cutter 9d may be arranged so as to face inward in the left-right direction. In the above-described embodiment, the compost is taken in the bucket by rotating the rotor 9 in the R1 direction. However, the rotor 9 may be turned around and mounted in a reversed manner, and the rotor 9 may be rotated in the R2 direction. Similarly, compost can be taken in. Further, the above embodiment is applied to the wheel loader,
You may make it apply to work vehicles (for example, tractors) other than a wheel loader.

In the correspondence between the above embodiment and the claims, the compost material constitutes a non-processed material, and the link member 31 constitutes a link mechanism.

[0024]

As described above in detail, according to the present invention, the rotor is attached to the front side of the bucket body so as to be rotatable in the width direction thereof, and the object stirred by the rotor is passed through the bucket through the passage. It was sent to the back side of the main body, guided to the side of the bucket main body by a belt conveyor, and dropped. Thereby, the air permeability of an object to be treated such as a compost material is increased, composting is promoted, and both the operability of the operator and the durability of the vehicle body are improved as compared with a system in which the bucket body is vibrated in small increments.

In particular, according to the second aspect of the present invention, the rear end of the passage is located above the upper surface of the belt of the belt conveyor, so that the compost material sent out through the passage is naturally dropped. No power is required to move over the belt and move the compost material from the aisle to the belt. According to the third aspect of the present invention, the belt conveyor is rotatably supported between the storage position and the use position, so that the vehicle can easily travel when not working. Claim 4
According to the invention, the belt conveyor is constituted by the first belt conveyor and the second belt conveyor which are arranged so as to be continuous with each other, and they are connected by the link. It is not necessary to use the belt conveyor, and when rotating between the storage position and the use position, if one belt conveyor rotates, the other belt conveyor also rotates, so that the structure is simplified. . Furthermore, according to the invention of claim 5,
Since the beam is spirally arranged around the circumference of the rotor rotation shaft and a cutter is attached to the circumference of the beam, the outermost diameter of the rotor increases, and a large amount of compost material is taken in.
Can be stirred.
