[0012]

Next, the operation will be described. The bucket conveyor 10 is rotated rearward about the lower rotating shaft 13 to the mixing position, and at least two kinds of desired cultivation soil such as red clay and humus or fertilizer are supplied to the supply hopper 4 of the mixing device 1. When the conveyor belt 5 is moved by rotating the roller 6 in this state, the soil on the conveyor belt 5 moves toward the bucket conveyor 10 (discharge side), and the inclined bucket conveyor 10 is discharged. The soil that has moved to the side is scraped diagonally rearward and upward, and the scraped soil is thrown upward and flows down toward the rear side, so that the soil thrown into the mixing device 1 is mixed. In this case, the soil on the discharge side that is moved by the conveyor belt 5 moves toward the portion that has been scraped up by the bucket conveyor 10, so that it is not compressed and is scraped obliquely rearward and upward by the bucket conveyor 10. The raised soil is not compressed because it is only thrown upward and flows down, so that no friction occurs between the soil particles of the soil and the soil particles do not collapse when mixed.

Therefore, when a plurality of soils and fertilizers having different properties are charged and mixed, and water, a chemical, or a liquid fertilizer is sprayed through the nozzle 27, the soil can be immediately used. In the case described above, the side of the bucket conveyor 10 is formed to have a width in which the frame 11 can rotate within the inner side of the side wall 3 of the supply hopper 4, but the portion other than the rotation range of the bucket conveyor 10 moves the bucket 16. Since the bulging portion 26 is provided so that the trajectory coincides with the inner surface, the soil in the supply hopper 4 always enters the bucket 16 and is raised, so that the non-working portion of the bucket 16 is not generated. Work efficiency is improved. That is, in the supply hopper 4, not only the moving direction of the transport belt 5 and the bucket conveyor 10, but also the transport belt that the left and right central sides advance due to the movement of the transport belt 5, and the soil on the side wall 3 collapses from the rear toward the center. Since the soil is circulated and mixed in the direction crossing the moving direction of the bucket 5, the bucket 16 acts over the entire width of the conveyor belt 5 to eliminate the non-working area, thereby further improving the efficiency of the mixing operation. Let it.

When the bucket conveyor 10 is rotated forward about the lower rotating shaft 13 to the discharge position, the soil on the conveyor belt 5 moves to the discharge side, and the bucket conveyor 1
It is lifted by the bucket 16 which inverts below 0, is thrown by the bucket 16 which inverts above, enters the discharge guiding gutter 25, is guided by the discharge guiding gutter 25 and is discharged. Therefore, the soil can be mixed and discharged only by changing the inclination angle of the bucket conveyor 10. in this case,
When the mixing operation is performed, as described above, the portion other than the rotation range of the bucket conveyor 10 is disengaged by the bulging portion 26 provided so that the movement trajectory of the bucket 16 and the inner surface coincide with each other. Although the working portion is reduced as much as possible, when the discharge operation is performed, the bucket conveyor 10 is rotated to the front position to the discharge position.
And a space between the bucket conveyor 10.

Therefore, the inner end of the chain guide 52 substantially parallel to the shielding plates 51 on both the left and right sides of the frame 11 of the bucket conveyor 10 has a cross section extending toward the rear (upper side) in the conveying direction of the conveying belt 5 in plan view. Since the soil collecting guide body 53 located on the side is provided, the soil conveyed toward the bucket conveyor 10 by the conveying belt 5 is further transferred to the bucket 16.
To the center of the working area. Therefore, the bucket 16 acts over the entire width of the conveyor belt 5 to reduce the non-operating area, thereby further improving the efficiency of the discharging operation.
Since the conveyor motor 17 is configured to be able to change the number of revolutions, it can be operated optimally depending on the condition of the soil, thereby improving work efficiency and mixing accuracy. In addition, since the conveyor motor 17 can also be rotated in the reverse direction, the soil in the bucket 16 can be dropped into the supply hopper 4 when the rotation is reversed, so that maintenance is facilitated.

Thus, the mixing device 1 includes the supply hopper 4
Because the caster wheel is provided at the bottom of the, it is easy to move, you can use the mixed soil immediately, like glue used for onion cultivation, mix the glue component with the soil, and use immediately after mixing Especially effective. Thus, the mixing device 1
Since at least a pair of left and right support legs 55 are provided at desired positions, when the support legs 55 are set at the support position, the caster wheel 30 and / or the wheel 31 do not act.
At the time of the mixing operation and the discharging operation of the mixing device 1, the vibration of the body is reduced. In addition, since the supporting legs 55 are configured to be freely relocated from a supporting position where the mixing device 1 is supported by being grounded to the floor surface and retracted from the floor surface to allow the mixing device 1 to move, the leg portions 55 can be detached one by one. The mixing device 1 can be moved without performing a troublesome operation or operation such as performing.

When the operation switch 37 of the operation box 35 on the side of the side wall 3 is set to automatic operation and the operation switch 37 is pressed, the conveyor motor 17 is driven for a time set in advance by the timer 39. After a lapse of a predetermined time, the conveyor motor 17 is stopped, and then the rotary screw shaft 21 is rotated by the motor 22, and the bucket conveyor 10 is moved from the mixing position by the top member 20 that is moved by the rotation of the rotary screw shaft 21. When it is rotated to the inclined discharge position and rotated to the discharge position, the discharge position detection sensor 43 detects this, stops the motor 22, and then drives the conveyor motor 17 again,
The soil in the supply hopper 4 is discharged.

An expiration sensor 47 connected to the control unit 42 is connected to the tank or hopper to which the bucket conveyor 10 is to be discharged. Is detected by the expiration sensor 47 and the conveyor motor 17 is stopped,
When the expiration sensor 47 detects a decrease in the soil, the conveyor motor 17 is driven again to discharge the soil in the supply hopper 4. Therefore, the automatic operation controlled to the discharge amount can be performed. In this case, a proximity operation switch proximity operation switch 45 and a proximity stop switch proximity stop switch 46 are provided separately from the operation box 35 on the side wall 3 of the bucket conveyor 10 on the discharge guide gutter 25 side.
And the proximity stop switch 46 has a higher priority than the switch of the operation box 35. Therefore, even during automatic operation, the proximity stop switch 46 can be stopped by the proximity stop switch 46. Automatic operation can be resumed, significantly improving operability.

When the operation switch 37 is pressed after switching to the manual operation by the automatic manual changeover switch 36, the motor 17 for the conveyor is driven, and after a desired time has elapsed, the motor 17 for the conveyor is stopped by the stop switch 38. The rotation switch 41 energizes the motor 22 by the rotation switch 41 to rotate the rotary screw shaft 21, and the bucket conveyor 10 is rotated from the mixing position to the forward inclined discharge position by the top member 20 which is moved by the rotation of the rotary screw shaft 21. When it is rotated to the discharge position, the discharge position detection sensor 43 detects this and stops the motor 22, and then drives the conveyor motor 17 again by the operation switch 37 to remove the soil in the supply hopper 4. Discharge. Therefore, the worker can work as he or she wants while watching the driving situation, so that detailed work becomes possible.
