Hereinafter, a configuration of an apparatus for injecting or spraying a liquid according to a preferred embodiment of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 1, an apparatus 10 for injecting or spraying a liquid includes a tank 20, a pump 30, a manifold 40, a reel 50, and a body 60. It is provided. The tank 20 stores a liquid, preferably a liquid fertilizer, to be injected or sprayed. The tank 20 is connected to the pump 30 by a first hose 99 provided at the bottom. The pump 30 supplies the fertilizer introduced through the first hose 99 to the manifold 40 through the second hose 98. The manifold 40 has a plurality of outlets 43 for dividing the fertilizer introduced from the pump 30 into a plurality of main bodies as necessary, as will be described later, and also for injection or spraying of liquid. It serves to keep the pressure of the liquid in the device 10 constant.

1, 2, and 3, the manifold 40 includes a first coupler 41 to which the second hose 98 is coupled, and a third hose 97 to return to the tank 20. It is provided with a second coupler 42 to be coupled, and a plurality of outlets 43 to which the connection hose 96 can be coupled, respectively, so as to be connected to the plurality of main bodies 60 as necessary. Referring to FIG. 3A, the first coupler 41 is connected to the second coupler 42 and the plurality of outlets 43 through a passage provided in the manifold 40.

Referring to Figure 3 (b), the passage connecting the first coupler 41 and the second coupler 42 is connected to two circular passages of different diameters. The smaller diameter passage 431 of the two circular passages is connected to the first coupling hole 41, and the larger diameter passage 432 is connected to the second coupling hole 42. Small diameter passage 431 is closed at its end. The end of the passage 432 having a large diameter is open to the outside of the manifold 40. The large diameter passage 432 is provided with a pressure regulator (45). The pressure regulating device 45 includes a fixing part 451 fixed to the passage, a slide part 452 inserted into the fixing part 451 and moving along the passage, and an elastic member 453. The fixing part 451 is fitted into the passage 432 from the outside of the manifold 40 and fixed. The fixing part 451 is determined in length so as not to block the second coupler 42. The fixing part 451 is provided with an insertion path 454 fitted to move the slide part 452. The slide portion 452 is in the form of a long straight rod, one side of which is fitted into the insertion path 454 of the fixing portion 451. On the opposite side is provided a head 455. The head 455 is caught by the stepped portion 433 formed at the position where the small diameter passage 431 and the large diameter passage 432 meet. An elastic member 453 is fitted to the slide portion 452. The elastic member 453 is a compression coil spring, one side of which is in contact with the fixing portion 451 and the other side of which is in contact with the head portion 455 of the slide portion 452, so that the slide portion 452 is always the stepped portion 433 of the passage. To the side.

Referring to FIGS. 3A and 3B, the pressure regulating device 45 normally has a head portion 455 of the slide portion 452 in contact with the stepped portion 433 by an elastic member 453. The small passage 431 and the large diameter passage 432 are blocked. Therefore, the liquid fertilizer introduced into the manifold 40 through the first coupler 41 flows into the outlet 43 without passing through the second coupler 42. If the pressure of the liquid fertilizer in the manifold 40 is increased (meaning that the pressure in the hose is increased at the same time), the head portion 455 of the slide portion 452 moves toward the passage 432 having a large diameter due to the pressure. It is pushed. Therefore, while the passage between the small diameter passage 431 and the large diameter passage 432 is opened, the passage is in communication with the second coupler 42, and some of the liquid fertilizer is connected to the tank 20 through the second coupler 42. Go back to). By the action of this manifold, if the fertilizer injector is temporarily inoperable or the pressure of the pump is increased to increase the pressure of the liquid in the device, the liquid fertilizer is circulated to the tank 20 to release the overpressure in the device. do.

Figure 4 shows another embodiment of the pressure regulator. A small diameter passage 431a extends further past the first coupler 41a. The passage 431a having a small diameter is provided with an extension portion 466 extending from the head portion 455a of the slide portion 452a. An end portion of the extension portion 466 is provided with a closing portion 470 having a size and shape that can block the first coupling hole 41. Normally, as shown, the head portion 455a of the slide portion 452a is in contact with the stepped portion 433a and the closing portion 470 at the end of the extension portion 466 does not block the first coupling hole 41a. Is further extended. If the pressure in the manifold 42a is high (meaning that the pressure in the hose is high at the same time), the small diameter passage 431a and the large diameter passage are pushed toward the large diameter passage 432a. The liquid fertilizer is opened between 432a so that the liquid fertilizer is directed toward the second coupler 42a, and at the same time, the liquid fertilizer no longer flows into the manifold 40a while the closure 470 blocks the first coupler 41a. Do not

Referring to FIG. 1, the fourth hose 96, one end of which is coupled to the outlet 43 of the manifold 40, is extended and wound around the reel 50, and the fourth hose 96 released from the reel 50. Opposite end of) is connected to body 60 of device 10 for injection or spraying of liquid. The fourth hose 96 may be configured to be easily coupled to and detached from the main body connecting portion 61 in a manner such as a one touch fitting. By this structure, the liquid fertilizer in the tank 20 is sent to the main body 60.

1 and 2, the main body 60 of the device 10 for the injection or spraying of liquid is the first and second members 62 and 64 connected in the form of two elongated circular pipes up and down. . The liquid fertilizer flows into the upper end of the first member 62 and is discharged to the lower end of the second member 64. The opening and closing lever 66 is provided on the upper portion of the first member 62 to open and close the flow path of the main body 60. The opening and closing lever 66 has a lever shape and one end is coupled to the first member 62. The flow path is opened when the opposite end is close to the first member 62 by pressing the open / close lever 66, and the flow path is closed when the lever 66 is released and the end thereof is far from the first member 62. Therefore, if the opening / closing lever 66 is not pressed by hand normally, even if the pump 30 is operating, a flow path will become clogged and liquid fertilizer cannot flow into the main body 60. FIG. Therefore, the opening and closing lever 66 must be kept pressed when injecting or spraying the liquid. In order to solve this inconvenience, an opening and closing lever fixing ring 68 was provided below the opening and closing lever 66. The fixing ring 68 serves to fix the end of the opening and closing lever 66 in close proximity to the first member 62.

The first and second bracing plates 69 and 70 are provided with a tightening screw 72 provided to tighten and loosen the separating portion 71. When the tightening screw 72 is loosened, passages in the centers of the first and second bracing plates 69 and 70 can be widened to move the bracing plate along the main body 60 up and down. When the tightening screw 72 is tightened, the first and second bracing plates 69 and 70 are fixed so as not to move on the main body 60. The method of tightening and releasing the first and second bracing plates 69 and 70 is not limited thereto. The clamp 74 as described later may be used. When the nozzle 80 of the main body 60 is planted in the ground, each of the upper portions of the first and second bracing plates 69 and 70 are held by hand, and the main body 60 is pressed. 69, 70) is not slippery can facilitate the operation.

The first member 62 and the second member 64 are coupled by the height adjustment clamp 74. Since the second member 64 has an outer diameter larger than that of the first member 62, the first member 62 is tightened and fixed so as not to move by the clamp 74 after the first member 62 is inserted into the second member 64. At this time, the length of the entire body 60 can be adjusted by inserting the first member 62 into or out of the second member 64 by an appropriate length. The clamp 74 includes a tightening part 741 and an opening and closing operation part 742. The tightening part 741 is a ring shape of which part is open, and the size of the tightening part 741 ring is adjusted according to the opening and closing of the opening and closing operation part 742 coupled to the tightening part 741. The opening and closing operation part 742 is connected to a screw part which penetrates through the open ends of the ring constituting the tightening part 741 and is connected. When the opening and closing operation part 742 is closed, the screw part is tightened again, thereby reducing the size of the ring. Accordingly, when the opening and closing operation portion 742 of the clamp 74 is opened, the height of the main body 60 can be adjusted by removing the first member 62 from the second member 64 or further inserting it into the second member 64. After closing and closing the opening / closing operation portion 742 of the clamp 74, the ring of the tightening portion 741 is tightened again, and thus the first member 62 and the second member 64 can be coupled and fixed. Such a clamp structure is known and is widely used for adjusting the height of a handle such as a kickboard.

2, a safety clamp 76 is provided at a lower end of the second member 64 of the main body 60. The safety clamp 76 may be coupled to the second member 64 using a clamp such as the height adjustment clamp 74, or the first support plate 69 and the second support plate 70 may be coupled to each other. It can be fixed to the second member 62 with a tightening screw or the like as used at the time. The safety clamp 76 is provided with a safety pin 761 slightly below the lower end of the second member 64. The safety pin 761 is provided at the end of the extension rod 762 extending from the safety clamp 76. The safety pin 761 is caught by the safety pin 761 when the underground injection nozzle 80 to be described later is separated so as not to be far away.

The ground spray nozzle 88 or the underground injection nozzle 80 is coupled to the lower end of the second member 64. The nozzle may be easily coupled to and detached from the main body by a one touch fitting method such as when the fourth hose 96 is coupled to the main body coupling part 61. However, the coupling method of the nozzle and the main body is not limited to this, and the main body and the nozzle may be combined by screwing or the like.

The underground injection nozzle 80 is long and pointed so that it can be easily planted underground. A depth control plate 82 is provided in the middle of the underground injection nozzle 80. Depth control plate 82 is to adjust the depth of the nozzle 80 according to the root position of the planted crop when injecting liquid fertilizer into the ground, it can be coupled to the nozzle to move up and down along the nozzle 80 have. The height adjusting plate 82 may be fixed to the nozzle by employing a clamp such as the height adjusting clamp 74 as described above, or a tightening screw as in the first and second support plates 69 and 70. After properly positioning the depth adjusting plate 82, the nozzle 80 is fixed to the main body 60 and driven into the ground, and the nozzle 80 is planted into the ground only up to the position of the depth adjusting plate 82. You can adjust the depth of the ground. On the other hand, the depth adjusting plate 82 may be made large enough to apply a force by stepping on the foot. Therefore, when planting the nozzle 80 in the ground, not only hand force but also foot force can be used. The tip of the underground injection nozzle 80 is pointed and dangerous, so when not in use, a safety cover 84 is provided to surround it.

Fog nozzles may be used as the ground spray nozzles 88, but the present invention is not limited thereto, and various nozzles on the market may be adopted according to purposes such as wide-angle nozzles.
