DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings showing the embodiments.
As shown in the figure, a net conveyor 1 on which cut turf can be placed and which can be continuously transported, a primary cleaning pipe 2 and a secondary cleaning pipe which are arranged above the net conveyor by being covered with a box 4. 3, an air blow pipe 5 disposed at the outlet of the box 4, water pumps 6 and 6 A for feeding water to the primary cleaning pipe 2 and the secondary cleaning pipe 3, and an air blow pipe 5. It comprises a ring blow 7 for blowing air, and a receiver 8 installed below the net conveyor 1 for collecting and draining water after washing.

The net conveyor 1 is made of a stainless steel wire having a diameter of about 2 mm which is stretched over a driving pulley 10 and a driven pulley 11 which are supported at both ends of a frame 9 which can be level-adjusted and is stepped. One end of the drive pulley 10 is an endless net conveyor formed in a mesh shape, having a width slightly larger than the cut turf, 40 to 50 cm, and a stretched length of about 5.5 to 6.5 m. By the drive motor 12
The speed is adjustable within a range of 6.5 to 19.5 meters per minute, and the drive is performed so that the vehicle can run continuously.

[0009] The upper running portion of the net conveyor 1 is
In order for the cut turf to be placed and transported smoothly in a horizontal state, the lower surface can be slid and guided by a guide plate 14 fixed on a bar 13 laid horizontally on the frame 9. A guide roller 15 rotatably and horizontally mounted on the frame 9 is provided so as not to hang down, and a positioning guide 16 for placing the cut turf on the net conveyor and transporting the cut turf is provided in front of the frame 9. I have.

A large number of cleaning pipes are disposed above the net conveyor 1, and the cleaning pipes include a plurality of primary cleaning pipes 2 and a plurality of secondary cleaning pipes 3 (in the embodiment, primary cleaning pipes 2 and 3). (Four pipes for washing and three pipes for secondary washing) are arranged at substantially equal intervals and covered with the box 4. A flexible flap 4A is provided at the entrance and the exit of the box 4 so that the cut grass placed on the net conveyor 1 can enter and exit freely, so that the entrance and the exit of the box 4 are closed. In addition, a viewing window 4B is provided on one side of the box 4 so that the inside of the box can be viewed.

The primary cleaning pipe 2 and the secondary cleaning pipe 3 are provided with a large number of nozzles 2A and 3A, respectively, arranged in a downward direction, and the primary cleaning pipe 2 and the secondary cleaning pipe 3 are provided. As shown in FIG. 3, a pipe nipple 17 for water supply is provided at one end of each, and both ends are supported by a support plate 18.
0 and a nut 21 are fastened and joined with a washer interposed therebetween. For example, a hole through which the bolt 20 passes through the support plate 18 and the support fitting 19 is made to be an elongated hole so that the height can be adjusted. It is mounted and fixed on the frame 9.

The height adjustment is performed in such a manner that the upper surface of the soil portion of the cut turf 22 placed on the net conveyor 1 with the soil portion upward and the lower end surface of the nozzle are in a range of about 1 to 8 cm. The height can be adjusted with.

The arrangement positions of the nozzles 2A, 3A provided downward on the primary cleaning pipe 2 and the secondary cleaning pipe 3 are, for example, as shown in FIG. By alternately arranging (A) and (B), which are arranged in a pipe at different positions, at substantially equal intervals,
The cleaning and removal of cut turf can be performed efficiently,
In this embodiment, the arrangement number of the nozzles 2A and 3A is set to 5 and 6 so that the arrangement positions are different. However, the arrangement position is not limited to this, and may be appropriately increased or decreased.

An air blow pipe 5 is disposed adjacent to an outlet of a box 4 covering the primary cleaning pipe 2 and the secondary cleaning pipe 3, and a large number of air blow pipes are provided. The nozzle 5A is disposed downward, and air is blown from the ring blow 7 to be ejected.

[0015] The deposits (pebble, pumice, moisture, etc.) remaining after washing and removing the soil of the cut turf can be efficiently removed without deforming or damaging the turf and the root of the turf. .

Water is supplied to the plurality of primary cleaning pipes 2 and secondary cleaning pipes 3 disposed in the cover box, and the plurality of primary cleaning pipes 2 and secondary cleaning pipes 2 are disposed in the cover box. Pipe nipple 17 provided at one end of pipe 3
From the primary cleaning pipe 2 to the water pipe 2
, And from the secondary washing pipe 3 to the water supply pipe 24, each is collected into one water supply pipe and connected via an open / close valve 25, and the water supply pipe 24 is connected to the water supply pump 6 from the water supply pipe 23. From the water supply pump 6A to supply water.

Then, the connection between the water supply pipe 23 and the water supply pipe 24 is closed by the opening / closing valve 25, water is supplied from the water supply pump 6 to the primary cleaning pipe 2, and then from the water supply pump 6A to the secondary cleaning water supply pipe 3. And the cut turf soil continuously conveyed on the net conveyor at a constant speed is efficiently washed and removed. Also, the connecting portion between the water pipe 23 and the water pipe 24 is opened and closed by the open / close valve 25. By opening and communicating, it is possible to supply water with either one of the water supply pumps 6 and 6A, and to cope with occurrence of trouble.

Further, the plurality of secondary washing pipes 3 are respectively collected to a water supply pipe 24 via an adjusting valve 26, and water is supplied from a water supply pump 6A.
The amount of water supply is adjusted by the adjusting valve 26 so that a fine finish cleaning of the cut turf roughly cleaned by the primary cleaning pipe 2 can be performed.

The lower part of the net conveyor 1 is filled with water containing cut turf soil and other adhering substances washed and removed by the primary cleaning pipe 2, the secondary cleaning pipe 3, and the air blow pipe 5. A receiver 8 for collecting is provided, and drain pipes 27 and 28 are provided from both side surfaces at the bottom of the receiver.
Is extended to one side in one direction and discharged to a sand basin 29, and the supernatant water collected in the sand basin is drained to sewage or the like. Alternatively, the supernatant water stored in the sand basin may be filtered and circulated by a water pump to be reused.

[0020]

As described above, according to the present invention, a plurality of primary cleaning pipes and a plurality of secondary cleaning pipes are provided above a net conveyor which is capable of continuously transporting cut turf cut into a square shape. Water and air are blown out from the washing pipe and the air blow pipe so that the soil and other deposits on the cut turf can be removed efficiently, so the equipment does not require an input conveyor, output conveyor, or roll cradle. Since it is possible to reduce the size of the device, to easily move and install it, and to manufacture it at low cost, it can be generally used.

Further, in order to remove soil from the root of the turf, there are means such as brushing with bristle, deforming, applying vibration, and removing water adhering to the turf after washing. Since it can be performed without adding a means for pressing and squeezing with a roller, the structure is simplified, and the quality can be improved without deforming the grass or damaging the roots.
