In the present embodiment, the direction in which the transport case 7 is inclined will be described as the front side, and the opposite side as the rear side.
The partition plate 2 is provided so as to divide the inside of the hopper 3 into two equal parts in the left-right direction with respect to the front-back direction in which the transport case 7 is inclined. Therefore, the partition plate 2 is disposed in close contact with the front and rear surfaces of the transport case 7.

On the left and right sides of the lower part of the transport case 7, granular material inlets 6 are formed, and each granular material inlet 6 has a shutter that can be opened and closed individually by driving means 21 such as an electric cylinder. 5 is installed.
The granular material introduction ports 6 are formed on the left and right sides of the lower part of the transport case 7 so as to open toward the respective chambers of the hopper 3 divided into the left and right chambers by the partition plate 2, and are opened and closed by the shutter 5. Is done.
The shutter 5 has a U-shape in plan view so as to surround and cover the powder inlets 6 on both the left and right sides of the lower part of the conveyance case 7 having a rectangular tube shape. The degree of opening and closing of the introduction port 6 can be adjusted.

The conveyor 8 is housed in the transport case 7. In this embodiment, the conveyor 8 is provided with buckets 23 at a constant pitch on the transfer belt 22 that extends over the transport case 7. Power is transmitted through the chain transmission mechanism 24, and a forward movement is made in the direction of the arrow. The drive means 9 is an electric motor that can be driven by a battery or the like mounted on an automobile.
Then, the granular material accommodated in the hopper 3 is scooped by the bucket 23 from the granular material inlet 6 on one side or both sides of the lower part of the conveying case 7 as the conveying belt 22 moves forward, and is conveyed upward. At the same time, it is inserted into the chute 25 at the upper end position of the transport case 7.

The chute 25 has a substantially rectangular tube shape and is connected to the front surface of the upper end of the transfer case 7. Further, it is oriented obliquely forward and downward in a side view, and is formed in a slightly downward tapered shape. The driving means 9 is installed on the front surface of the chute 25.
A discharge pipe 26 is connected to the lower end of the chute 25. The discharge pipe 26 includes a flexible pipe portion 27 made of a bellows pipe connected to the lower end portion of the chute 25 and a straight pipe portion 28 connected to the lower end of the flexible pipe portion 27. The part 28 can be extended and contracted in the longitudinal direction by a telescopic structure or the like, and an opening / closing control switch 29 of the driving means 21 of the shutter 5 and an operation switch 30 of the driving means 9 of the conveyor 8 are provided at the lower end thereof. In FIG. 1, 31 indicates a switch cord, and 32 indicates a battery cord.

An openable / closable shutter 36 is provided near the lower end of the chute 25 below the overflow opening 33. By opening the shutter 36, the flow of fertilizer from the chute 25 to the discharge pipe 26 is allowed and closed. As a result, the flow of fertilizer is regulated so as not to enter the discharge pipe 26.

The shutter 36 may be configured to be manually opened / closed from the outside of the chute 25, or may be configured to be automatically opened / closed using driving means such as an electromagnetic solenoid.
As shown in FIG. 1, a load carrying member 37 formed by a porous member such as a wire mesh that allows passage of fertilizer is provided at the lower part in the hopper 3. This prevents the fertilizer from being compressed.
That is, when a large amount of fertilizer is accumulated in the hopper 3, the fertilizer in the lower part of the hopper 3 is compressed by the load, and the bridging phenomenon of the fertilizer occurs, or the compressed fertilizer causes the driving means 9 of the conveyor 8 to move. Although an excessive load was applied, there was a risk of failure, slipping of the transfer belt 22, and the like. However, by providing the load carrying member 37, it is possible to reduce the application of compressive force to the fertilizer below the hopper 3, bridge phenomenon, etc. Is prevented.

  As shown in FIG. 5, the unloading device 1 configured as described above moves to a field where the fertilizer machine 40 is mounted on the loading platform 39 of the truck 38 and waits for the lower end portion of the discharge pipe 26 to remain on the loading platform 39. The fertilizer applicator 40 is directed to the fertilizer hopper 41. At this time, since the hopper 3 can be rotated about the vertical axis with respect to the gantry 13, the hopper 3 is rotated and positioned with the positioning pins 19 so that the front surface of the transfer case 7 faces the fertilizer applicator 40. It is. In the case where the fertilizer machine 40 is waiting in the fields on both sides of the farm road, the hopper 3 may be rotated and positioned so that the front surface of the transport case 7 faces the side surface of the loading platform 39 of the truck 38.

Next, by operating the conveyor 8, the fertilizer in the hopper 3 is scooped up by the bucket 23, transported upward, put into the chute 25 at the upper end, and fertilizer from the discharge pipe 26 to any fertilizer hopper 41 of the fertilizer applicator 40. The fluid is supplied by its own weight.
In this case, the inside of the hopper 3 is divided into two chambers by the partition plate 2, and different types of fertilizers can be put into these two chambers. If both the left and right shutters 5 at the bottom of the transport case 7 are opened to the same degree of opening, the two types of fertilizer in the hopper 3 are transported in equal amounts from the powder inlets 6 on the left and right sides. 7, it is picked up by the bucket 23, transported into the chute 25, and discharged from the discharge pipe 26 to the fertilizer hopper 41 of the fertilizer applicator 40. Thereby, the fertilizer hopper 41 of the fertilizer applicator 40 can be supplied with a mixture of two types of fertilizers in equal amounts. By setting the degree of opening of the left and right shutters 5 to a desired ratio such as 1: 2 or 1: 3, the mixing ratio of the two types of fertilizer can be set to a desired ratio such as 1: 2 or 1: 3. The fertilizer hopper 41 of the fertilizer applicator 40 can be supplied in a ratio.

Further, when the shutter 36 below the chute 25 is closed and the conveyor 8 is operated, the fertilizer conveyed upward by the bucket 23 and thrown into the chute 25 flows out from the overflow opening 33 to the overflow pipe 34 and overflows by its own weight. It slides in the pipe 34 and is discharged (refluxed) from the discharge port 35 to the center of the hopper 3. If this is continued, the two types of fertilizer in the hopper 3 are gradually and uniformly mixed.
The fertilizer thus mixed can be taken out and supplied to the fertilizer applicator 40 through the discharge pipe 26 by opening the shutter 36 below the chute 25.

In order to mix the three types of fertilizer, first, the two types of fertilizer are put into the two chambers of the hopper 3 separately, and then the third type fertilizer is put into the two chambers in an equal amount, What is necessary is just to operate the conveyor 8 by closing the shutter 36. The same may be done when three or more kinds of fertilizers are mixed.
It is possible to mix the fertilizer only on the one chamber side of the hopper 3. In that case, only one shutter 5 of the transport case 7 is opened, and the other overflow opening 33 is closed by a shutter or the like, and is returned to one chamber of the hopper 3 from one overflow pipe 34. Good. In this case, the overflow opening 33 is also provided with a shutter that can be opened and closed.

FIG. 6 shows another embodiment of the present invention, in which the inside of the transport case 7 is divided into two left and right chambers by a dividing plate 42, conveyors 8a and 8b are provided in the respective chambers, and buckets are provided on the transfer belts 22a and 22b. 23a and 23b are installed at an equal pitch, the drive shaft 43 of both conveyors 8a and 8b is used as one common shaft, and the drive shaft 43 is rotationally driven by the drive means 9 via the chain transmission mechanism 24. It is. Other configurations are the same as those in the above embodiment. The dividing plate 42 is disposed on the same dividing surface as the partition plate 2 that partitions the inside of the hopper 3.
In the case of this embodiment, the fertilizers in the two chambers in the hopper 3 can be divided and conveyed by the buckets 23a and 23b of the separate conveyors 8a and 8b. Therefore, for example, when mixing an equal amount of fertilizer in the hopper 3, the accuracy of the mixing ratio is improved. In this case as well, the amount of fertilizer introduced into the transport case 7 from the granular material inlet 6 is adjusted by adjusting the degree of opening of the shutters 5 on the left and right sides of the transport case 7.

The embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and can be implemented with appropriate design modifications within the scope of the claims.
Moreover, the granular material targeted by the present invention may be not only a fertilizer but also a soil conditioner, a disinfectant, and other granular materials, and the supply target is not limited to the fertilizer application 40. Absent.
