When the vine needs to be transplanted, the expansion layer is contracted by sliding the piston downwards along the water storage pipe, so that most of the outer periphery of the expansion layer is separated from the vine, thereby facilitating the vine to be peeled off from the outer periphery of the expansion layer and minimizing the damage to the vine when the vine is peeled off from the expansion layer.

Description

TECHNICAL FIELD

[0002] Vine is a kind of wood or herbaceous climbing plant that is easy to bend or soft, and needs to grow upward through a climbing frame during the cultivation of vine. Since the traditional climbing frame is generally a simple rod, the vine will be wound on the rod. When the vine needs to be transplanted, the vine wound on the rod is not convenient to peel off from the rod, and if forcibly peeled off, the stems of the vine may be damaged, affecting the survival rate of the vine. SUMMARY

[0003] The present application aims to provide a vine climbing frame to overcome the above-mentioned defects in the prior art.

[0004] According to the vine climbing frame of the present application, the vine is planted in the planting box, and during the growth of the vine, the expansion layer is in an expanded state, so that the circumferential wall of the expansion layer forms a wavy shape, which is conducive to the vine climbing upward along the expansion layer to the horizontal frame. When the vine needs to be transplanted, the expansion layer is contracted by sliding the piston downward along the water storage pipe, so that most of the outer periphery of the expansion layer is separated from the vine, which is conducive to the vine peeling off from the outer periphery of the expansion layer, and minimizes the damage to the vine when the vine peels off from the expansion layer.

When the vine needs to be transplanted, the expansion layer is contracted by sliding the piston downward along the water storage pipe, so that most of the outer periphery of the expansion layer is separated from the vine, which is conducive to the vine peeling off from the outer periphery of the expansion layer, and minimizes the damage to the vine when the vine peels off from the expansion layer.

[0012] The tubular valve body is further provided with an exhaust pipe fixed between the tubular valve body peripheral wall and the exhaust disc bottom surface, the exhaust pipe is communicated with the tubular valve body and the exhaust disc, the distance between the exhaust pipe end on the tubular valve body and the uppermost sealing ring is less than the distance between the limiting disc and the water storage pipe top wall, the distance between the exhaust pipe end on the tubular valve body and the intermediate sealing ring is greater than the distance between the limiting disc and the water storage pipe top wall, and the support pipe upper end is provided with an exhaust hole, and the exhaust disc is communicated with the outside through the exhaust hole.

[0041] Referring to Figure 6 , Figure 7The switching valve assembly comprises a tubular valve body 54, an exhaust disc 52 and a tubular valve core 60. The tubular valve body 54 is fixed on the upper end of the water storage pipe 50. The exhaust disc 52 is hollow inside and has an open upper end. The tubular valve body 54 is in communication with the exhaust disc 52 and the water storage pipe 50. The tubular valve core 60 is slidingly connected in the tubular valve body 54. Three sealing rings 64 are fixed on the outer periphery of the tubular valve core 60 and are equidistantly distributed along the axial direction of the tubular valve core 60. The outer periphery of the sealing ring 64 is in abutment with the inner wall of the tubular valve body 54. An outer communication hole 541 is formed in the peripheral wall of the tubular valve body 54 and is in communication with the partition cavity 70. An inner communication hole 601 is formed in the peripheral wall of the tubular valve core 60 and is located between the uppermost sealing ring 64 and the intermediate sealing ring 64. A limiting disc 61 is fixed on the lower end of the tubular valve core 60 and is in abutment with the piston 51. The movable distance of the limiting disc 61 is greater than the distance between the uppermost sealing ring 64 and the intermediate sealing ring 64. The frictional force between the sealing ring 64 and the inner wall of the tubular valve body 54 is greater than the thrust of the gas pressure in the water storage pipe 50 on the top wall in the tubular valve core 60.

[0042] With reference to Figure 6 An exhaust pipe 53 is fixed between the peripheral wall of the tubular valve body 54 and the bottom surface of the exhaust disc 52. The exhaust pipe 53 is in communication with the tubular valve body 54 and the exhaust disc 52. The distance between the upper end of the exhaust pipe 53 on the tubular valve body 54 and the uppermost sealing ring 64 is less than the distance between the limiting disc 61 and the top wall of the water storage pipe 50. The distance between the upper end of the exhaust pipe 53 on the tubular valve body 54 and the intermediate sealing ring 64 is greater than the distance between the limiting disc 61 and the top wall of the water storage pipe 50. An exhaust hole 402 is formed in the upper end of the support pipe 40. The exhaust disc 52 is in communication with the outside through the exhaust hole 402.

[0043] With reference to Figure 6 The valve core 63 is fixed on the upper end of the tubular valve core 60. When the valve core 63 is pressed, the gas in the tubular valve core 60 can pass through the valve core 63.

[0044] With reference to Figure 6 A limiting ring 62 is fixed on the inner wall of the tubular valve body 54 and surrounds the tubular valve core 60. The limiting ring 62 is located below the lowermost sealing ring 64.

[0045] With reference to Figure 1 The horizontal frame comprises a crossbar 32, a plurality of extension rods 31 and two connecting rods 30. The two connecting rods 30 are fixed on the two side surfaces of the planting box 10, respectively. The two ends of the crossbar 32 are detachably connected to the upper ends of the two connecting rods 30. The crossbar 32 is in abutment with the upper end of the support pipe 40. The extension rods 31 are perpendicular to the crossbar 32 and are detachably connected to the crossbar 32. The length of the exhaust hole 402 is greater than the width of the crossbar 32, so as to ensure that the exhaust hole 402 is not covered by the crossbar 32, thereby ensuring the air permeability of the exhaust hole 402.

[0046] In the use of the present application, the soil is filled into the planting box 10, the surface of the soil is slightly lower than the upper end of the bottom pipe 11, then the vertical limiting groove 412 in the plug-in pipe 41 at the lower end of the vertical frame is aligned with the clamping pin 16, then the plug-in pipe 41 is inserted into the bottom pipe 11, the vertical frame is rotated, so that the clamping pin 16 is clamped into the horizontal limiting groove 411, so that the vertical frame is fixed on the bottom pipe 11.

[0047] Then the two ends of the horizontal rod 32 are embedded in the upper ends of the two connecting rods 30 by means of mortise and tenon connection, and a plurality of extension rods 31 are embedded on the horizontal rod 32 by means of mortise and tenon connection to form a horizontal frame.

[0048] The water pump 12 is connected with the water supply pipe, the water pump 12 and the electromagnetic valve 14 are started, the electromagnetic valve 14 is started to be in the on state, the water pump 12 injects the liquid water in the water supply pipe into the bottom pipe 11 through the water injection pipe 13, because the pore size of the capillary hole 110 is small, most of the liquid water injected into the bottom pipe 11 enters the water storage pipe 50 through the through hole at the lower end of the support pipe 40, so that the piston 51 moves upward, so that the air on the upper side of the piston 51 enters the separation cavity 70 through the tubular valve core 60, the inner communication hole 601 and the outer communication hole 541, and then enters the inflation cavity 201 through the inflation hole 401, so that the expansion layer 20 expands, and the peripheral wall of the expansion layer 20 forms a wave shape, which is conducive to the climbing of the vine plants thereon.

[0049] When the piston 51 moves upward to abut against the limiting disc 61, as the liquid water continues to be injected, the piston 51 drives the tubular valve core 60 to move upward to abut against the top wall in the water storage pipe 50, so that the inner communication hole 601 and the outer communication hole 541 are misaligned, at this time the outer communication hole 541 is located between the intermediate side sealing ring 64 and the lowermost sealing ring 64, so that the air in the expansion layer 20 cannot be discharged through the outer communication hole 541, ensuring that the expansion layer 20 is in an inflated state.

[0050] At this time, the end of the exhaust pipe 53 is located between the uppermost sealing ring 64 and the intermediate sealing ring 64, so that the inner communication hole 601 is communicated with the exhaust pipe 53, so that the air in the tubular valve core 60 is communicated with the atmospheric pressure through the inner communication hole 601, the exhaust pipe 53, the exhaust pipe 53 and the exhaust hole 402, so as to facilitate the downward movement of the piston 51 during irrigation.

[0051] When the expansion layer 20 stops expanding, the limiting disc 61 abuts against the top wall in the water storage pipe 50, at this time the lower side of the piston 51 is filled with liquid water, the electromagnetic valve 14 is closed, in the growth process of the vine plants, if the water in the soil is reduced due to absorption or evaporation, the water in the bottom pipe 11 is absorbed into the soil through the capillary action of the capillary hole 110, so as to ensure that the soil remains moist and realizes irrigation of the vine plants, and further ensures the normal growth of the vine plants.

[0052] When the vine needs to be transplanted, the electromagnetic valve 14 is restarted, and the water pump 12 is started in reverse, so that the water pump 12 draws the liquid water on the lower side of the piston 51 back into the water supply pipe until the piston 51 moves to the lower end of the water storage pipe 50.

[0053] At this time, the cross rod 32 is detached from the connecting rod 30, and a thin rod is inserted through the exhaust hole 402 and contacts the upper end of the valve core 63, and the thin rod is pressed downward, so that the tubular valve core 60 moves downward until the lowermost sealing ring 64 abuts against the limiting ring 62, thereby realizing that the inner communication hole 601 is in communication with the outer communication hole 541, and since the valve core 63 is pressed, the air in the tubular valve core 60 can be discharged through the valve core 63.

[0054] The air in the inflation cavity 201 enters the tubular valve core 60 through the outer communication hole 541 and the inner communication hole 601 and is discharged through the valve core 63, so that the expansion layer 20 shrinks, and the original expansion part of the expansion layer 20 is separated from the vine, so as to facilitate the vertical frame to be separated from the stem of the vine, thereby reducing the damage to the vine when the vine is separated from the vertical frame.

[0055] After the vertical frame is separated from the vine, the vine is dug out of the soil to realize the transplantation of the vine.

[0056] Those skilled in the art can clearly make various modifications to the above embodiments without departing from the overall spirit and concept of the present application. All of them fall within the protection scope of the present application. The protection scheme of the present application is subject to the claims attached to the present application.
