And the water tank part 40 is fixed to the lower part of the frame 10 and has a main body 41 with an open upper part, and the upper part of the main body 41 is fixed at an angle to one side to form a drain hole 42a on one side. It is formed of a cover 42 that forms a, and a filter 43 that is detachably formed in the drain hole 42a to filter out foreign substances flowing into the body 41 together with water.

A water level adjusting unit 44 is formed inside the main body 41 to be connected to the faucet, to grasp the water level, and to replenish water when water is insufficient.

During automatic operation, the control unit 60 controls the transport unit 30 to move the mushroom medium to the water supply unit 20 by moving the plate 33a of the chain belt 33 in units of 1 or 2 or more units. When the number of mushroom mediums that have reached the water supply unit 20 matches the set number of mushroom mediums, the water supply unit 20 supplies water to the mushroom medium and returns to the original position. And it is formed to control the pump unit (50).

On the upper surface of the driven sprocket 32a, a first display unit 71 indicating the movement of the plate 33a in units of 1 or 2 units or more, and a second display unit 71 indicating the water supply time of the water supply unit 20 Each of the display units 72 is formed, and the sensor unit 70 is connected to the control unit 60 to sense the first display unit 71 and the second display unit 72 on the upper portion of the transport unit 30 . is formed

The operating state of the automatic needle rod system having such a configuration will be described as follows.

5 to 8 , the operator operates the control unit 60 to move the mushroom medium toward the water supply unit 20 in units of one or two or more spaces of the plate 33a.

The plate 33a moves in units of one or two or more spaces, as the plate 33a of the chain belt 33 that was behind moves to the seat of the plate 33a that was in front with a time difference, and the plate 33a moves by one space. The silver carrying unit 30 rotates at a low speed, and moving in units of two or more spaces is a high-speed rotation of the carrying unit 30 .

Therefore, at the starting point, the operator moves the mushroom medium to the holder member 34 and the plate 33a of the chain belt 33 on which the mushroom medium is mounted sequentially toward the water supply unit 20 in units of 1 or 2 or more spaces. will do

That is, when the driving motor 35 is rotated by the control unit 60 , the driving shaft 31 and the driving sprocket 31a connected to the driving motor 35 rotate in a clockwise direction, and are connected by a chain belt 33 . Since the driven shaft 32 and the driven sprocket 32a are also rotated clockwise together, the plate 33a of the chain belt 33 on which the mushroom medium is mounted is sequentially supplied to the water supply unit 20 in units of 1 or 2 or more spaces. ) will move toward

Meanwhile, in the holder member 34, as the first holder 34a holds the lower part of the mushroom medium and the second holder 34b carries the periphery of the mushroom medium, the mushroom medium is moved from the transport unit 30. does not fall

In addition, as the first bar 100a and the second bar 100b of the fall prevention unit 100 prevent the mushroom medium from falling in the straight section and the curved section of the transport section 30, respectively, the mushroom medium is moving It does not fall from the carrying part (30).

And in the second guide part 90, the roller 91 distributes the load of the chain belt 33 and transmits it to the rail 92, and the rail 92 guides the roller 91 to move in a predetermined horizontal track. As it is supported, the chain belt 33 does not depart from the transport unit 30 .

As shown in FIG. 6 , when the plate 33a of the chain belt 33 on which the mushroom medium is mounted is sequentially moved toward the water supply unit 20 in units of one or two or more spaces, the sensor unit 70 is By detecting the first display unit 71 on the upper surface of the rotating driven sprocket 32a, the control unit 60 is notified that the plate 33a moves in units of 1 or 2 spaces or more.

Accordingly, the control unit 60 may control the rotation speed of the driving motor 35 by the sensor unit 70 sensing and counting the first display unit 71 .

Then, when the sensor unit 70 detects the second display unit 72 of the driven sprocket 32a, the sensor unit 70 notifies the control unit 60, so that the control unit 60 at this time the water supply unit 20 will make it work

As shown in FIG. 7 , when the mushroom medium is loaded onto the transport unit 30 and reaches the water supply unit 20 , the control unit 60 sets the number of mushroom mediums arriving at the water supply unit 20 with the set number of mushroom mediums and Whether the match is confirmed through the sensor unit 70, and if there is no abnormality, the water supply unit 20 operates to supply water to the mushroom medium.

That is, when the control unit 60 controls the pressure generating unit 26 and the pressure generating unit 26 supplies pressure to the cylinder 21 , the piston rod 22 at the upper end of the cylinder 21 moves downward. And, the pipe 24 connected to the piston rod 22 and the first link 23 also moves in the downward direction.

At this time, the first guide part 80 guides and supports the pipe 24 to move only in the downward direction without rotating through the second link 81 , the slide bar 82 , and the support member 83 .

Therefore, when the pipe 24 moves downward, the pump unit 50 is operated by the control unit 60 to supply water to the water tank unit 40 to the pipe 24 of the water supply unit 20, and the pipe ( An appropriate amount of water is injected into the mushroom medium while the needle rod 25 connected to 24) is inserted into the upper part of the mushroom medium.

Thereafter, when the water supply time set in the control unit 60 is over, the control unit 60 stops the operation of the pump unit 50 and, at the same time, the control unit 60 moves the water supply unit 20 upward again to return to the original position. control to do

Then, the mushroom medium after the water supply is sequentially moved to the starting point through the transport unit 30 .

Therefore, as water can be automatically supplied to the mushroom medium, the working time can be shortened, and an appropriate amount of water can be injected into the mushroom medium, so it is possible to oversupply or insufficiently supply water to the mushroom medium. It can prevent the rotting of the seed or growth of the seed.

As shown in Figures 7 and 8, the water flowing down from the water supply unit 20 and the mushroom medium falls first to the inclined cover (42).

And the water that has fallen on the cover 42 flows to the drain hole 42a along the inclined surface of the cover 42, but as the filter 43 is attached to the drain hole 42a, foreign substances flowing down together with the water are removed from the filter 43 ), and only water flows into the body 41 and is stored.

In addition, as the water level control unit 44 is connected to the faucet to adjust the water level inside the body 41, when the water tank unit 40 runs out of water, the water level control unit 44 activates the water. Water is automatically replenished to the grandfather 40 .

Therefore, as the water flowing down during the water supply process can be re-filled in the mushroom medium and reused, water consumption can be reduced, and water does not fall to the floor, thereby preventing safety accidents caused by stagnant water on the floor in advance.

On the other hand, as the wheel 11 runs on the lower part of the frame 10, it is easy to transport and store because it does not occupy a lot of space due to the design of the volume.
