By the way, as root vegetables 2, there are carrots, radish, potatoes, potatoes and the like having root hair.

[0008] The cargo receiving conveyor 3 is horizontally arranged from one side in the longitudinal direction of the cargo receiving water tank 1 in the shape of a plane rectangular box with an open upper surface toward the vicinity of the other side, and is thrown into the tank and piled up. The root vegetables 2 placed on the water tank 1 are transported to the unloading side, and in this embodiment, the water tank 1 has an appropriate width.
Is a so-called slat conveyor in which a large number of strip-shaped plates formed to extend over the entire length in the lateral direction are connected to each other in a belt shape so as to be adjacent to each other. It is arranged so as to be connected to a drive machine such as a motor (not shown) installed.

It is desirable that the cargo receiving conveyor 3 is installed in a state of being separated from the bottom of the cargo receiving water tank 1 upward as shown in the figure. That is, the root vegetables 2 with the mud immediately after being harvested are thrown into the receiving water tank 1 as they are, and the mud washed with the stored water and peeled off from the root vegetables 2 is accumulated on the bottom of the tank, and the conveyor 3 Since it will hinder the movement of the
It is desirable to install it apart from the bottom of the tank.

Further, as shown in the figure, a plurality of rollers 7, which are connected to a driving machine of the conveyor 3 and are driven to rotate, are disposed on the unloading side of the cargo receiving conveyor 3 with a gap 8 therebetween. At the very least, the root vegetables 2 that have been conveyed to the discharge portion side are configured to pass on the rollers 7 and be transferred to the carry-out conveyor 4. That is, the cargo receiving conveyor 3 includes a slat portion 3-1 composed of a slat conveyor, and a roller portion 3-2 arranged with a gap 8 between them in the extension direction from the carry-out end portion of the slat portion 3-1. And the root vegetables 2 thrown into the aquarium 1 are slats.
It is configured so that it is piled up on 1 and is carried to the roller section 3-2 by this slat section 3-1 and transferred to the carry-out conveyor 4. Roller part 3-2 gap 8
In the case of root vegetables 2, for example, radish, it is made slightly narrower than its thickness so that the radish does not fall and the mixed water of water and air jetted from each jet nozzle 6 of the jetting device 5 ... The spraying force is not inferior, and it quickly passes and is sprayed toward the root vegetables 2 passing through the roller portion 3-2,
The jetting force pushes up the root vegetables 2 so that the entanglement is removed.

The rotation speeds of the slat portion 3-1 and the roller portion 3-2 are the same, or the roller portion is faster than the slat portion 3-1.
3-2 Speed up. Roller section 3-rather than slat section 3-1
By increasing the rotation speed on the 2 side, when the root vegetables 2 are transferred from the slat part 3-1 to the roller part 3-2, the root vegetables 2 are transferred so as to be pulled to the roller part 3-2 side. Therefore, the effect of separating the root vegetables 2 in which the root hairs are entangled with each other can be obtained. That is, the effect of removing the entanglement can be obtained.

The carry-out conveyor 4 conveys the root vegetables 2 transferred from the load-receiving conveyor 3 to the outside of the tank by its own drive rotation, for example, is installed next to the load-receiving water tank 1 and stores washing water (not shown). Of the root vegetables 2 on the surface (the surface on which the root vegetables 2 is placed) formed to have a width substantially the same as the conveyor width of the cargo receiving conveyor 3 in order to convey the root vegetables 2 to the cleaning water tank. Is a belt or slat conveyor having hooking edges 9 protruding in parallel in the rotational direction so as to prevent the root vegetables 2 from rolling down.
From the roller section 3-2 of the receiving conveyor 3 to the receiving water tank 1
The root vegetables 2 transferred from the cargo receiving conveyor 3 by arranging so as to face the outside from the upper opening of the
Are transported outside the tank.

The injection device 5 is installed in the cargo receiving water tank 1 as shown in the drawing, and mixes the water stored in the water receiving tank 1 with the air from the air intake port 10 that is piped outside the tank. While it is a submersible pump that makes a motion of injecting the mixed water toward the root vegetables 2 on the receiving conveyor 3 from each of the injection nozzles 6 ... With a predetermined injection force while sucking water and air from each of the injection nozzles 6 ... It is designed to spray mixed water. By the way, the predetermined ejection force means each ejection nozzle 6 ...
The mixed water sprayed from the piles is piled up on the receiving conveyor 3 and conveyed to the unloading side of the conveyer 3, where the water pressure is wide enough to reach a million valves between the two groups of root vegetables. The root vegetables 2 can be pushed up to gradually collapse the piled state, while the water pressure is set to a level that does not damage the root vegetables 2.

The injection nozzles 6 are disposed at the height at which the load receiving conveyor 3 is disposed or at a position slightly lower than or higher than that, and at the position above the load receiving conveyor 3, the roller portion on the discharge side of the load receiving conveyor 3.
It is arranged in a concentrated manner on 3-2 so that the mixed water can be intensively sprayed toward the root vegetables 2 passing through the roller portion 3-2 from the vertical direction or diagonally rearward. That is, by intensively spraying the mixed water onto the root vegetables 2 passing through the roller portion 3-2, the entangled root vegetables 2 are effectively and surely disentangled, and each hooking edge 9 on the surface of the carry-out conveyor 4 is removed. Try to transfer one at a time.

Next, the operation of the entanglement and disentanglement device of the present embodiment constructed as described above will be explained. The slats of the cargo receiving conveyor 3 are thrown into the cargo receiving water tank 1 through the upper opening.
When a large amount of root vegetables 2 were piled up on 3-1,
The conveyor 3 is actuated and the jetting device 5 is actuated to jet the mixed water from the jet nozzles 6 ... The mixed water sprayed from each of the spray nozzles 6 spreads to the roller section 3-2 side by the slat section 3-1 and spreads over 10,000 groups between the two groups of root vegetables, and collides with the intertwined root hairs of each root vegetable 2. By doing so, the root vegetables 2 are pushed up from below by the mixed water that passes through the gaps 8 in the roller portion 3-2 and the piled state is gradually collapsed while the root vegetables 2
Massage. At this time, root vegetables 2 in which bubbles of mixed water are intertwined
It enters into the space and ruptures, and the rupture exerts the effect of disentangling the entanglement of the root hairs of the root vegetables 2 that are entangled with each other. The conveyors 4 are transferred and carried out one by one to a cleaning water tank outside the tank for cleaning, for example.

In the above embodiment, the cargo receiving conveyor 3 has been described in detail as a configuration including the slat portion 3-1 and the roller portion 3-2, but the configuration is not limited to such a configuration, and for example, the cargo receiving conveyor 3 as a whole. It is of course possible to use a slat conveyor or a roller conveyor, and the conveyors are not limited to these conveyors and may be conveyors having other structures having a gap 8 penetrating in the vertical direction. What is essential is that the conveyor has a structure capable of transferring a large amount of root vegetables 2 and at least a gap 8 through which the mixed water sprayed from each spray nozzle 6 passes, on the unloading side.
