The telescopic support rod includes a sleeve, and a movable rod is slidably installed inside the sleeve. A piston located inside the sleeve is fixedly connected to the bottom end of the movable rod. A filter screen is threadedly connected to the inner wall of the bottom of the sleeve. A counterweight mechanism is detachably installed at the bottom end of the telescopic support rod. This utility model, through the arrangement of the sleeve, movable rod, piston, and through-hole, allows water injected into the counterweight tank to enter the sleeve through the through-hole during use. The piston pushes the frame body at the top of the movable rod upward, achieving height adjustment. After adjustment, maintaining the water pressure in the counterweight tank and sleeve keeps the frame body at a fixed height, effectively preventing the frame from sliding down due to the increased weight of grape branches, leaves, and fruit, ensuring stability after height adjustment.

Description

Technical Field

[0001] This utility model relates to the field of grape cultivation technology, and more specifically, to a grapevine trellis. Background Technology

[0002] Grapes are vine plants with flexible branches and stems that cannot grow upright. During cultivation, trellises are needed to facilitate the growth of grapes. The trellises can spread out the branches, leaves and fruit clusters, preventing the branches and leaves from shading each other, allowing more leaves to receive sufficient sunlight, and also improving ventilation between branches and leaves, reducing fungal diseases caused by high humidity.

[0003] A search revealed a Chinese patent application with patent number 202221542429.X, which discloses a Y-shaped trellis beneficial for grape cultivation. The trellis includes a telescopic support rod, the lower end of which is fixedly connected to a base. The upper end of the telescopic support rod is symmetrically and movably connected to a movable support arm via a connecting bracket. The upper ends of the two movable support arms are connected by a connecting rod. A horizontal crossbar is also fixedly connected through the movable support arm, and a lighting strip is fixedly connected to the bottom of the connecting rod. This utility model, through its telescopic support rod, allows for height adjustment of the Y-shaped grape cultivation trellis. By rotating the lower end of the movable support arm to the connecting bracket and symmetrically opening mounting holes at both ends of the connecting rod, the structure of the Y-shaped grape trellis can be adjusted to accommodate different grape varieties. Furthermore, by fixing a lighting strip to the bottom of the movable support arm, the photosynthetic efficiency of the grapes can be improved in low light conditions or rainy weather. However, the patent has the following shortcomings: after height adjustment, the telescopic support rod is fixed solely by the friction between the adjusting head and the movable rod. As the grape branches and fruits grow, the weight gradually increases, easily leading to fixation failure. Therefore, this utility model proposes a new solution. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the above-mentioned patent where the height of the telescopic support rod is adjusted and fixed only by the friction between the adjusting head and the movable rod, which easily leads to fixation failure as the grape branches, leaves and fruits grow and the weight gradually increases. Therefore, a grapevine vine traction frame is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A grapevine trellis includes a frame and also includes: A telescopic support rod is installed at the bottom of the frame. The telescopic support rod includes a sleeve. A movable rod is slidably installed inside the sleeve. A piston located inside the sleeve is fixedly connected to the bottom end of the movable rod. A filter screen is threadedly connected to the bottom inner wall of the sleeve. The counterweight mechanism is detachably installed at the bottom of the telescopic support rod. The counterweight mechanism includes a frustum-shaped counterweight water tank. A water inlet pipe is installed through the top of the counterweight water tank. A drain pipe is installed on the side wall of the water inlet pipe near the bottom. Valves are installed in the middle of both the water inlet pipe and the drain pipe. The counterweight water tank has a through hole at the top center that cooperates with the telescopic support rod. Multiple leveling mechanisms are evenly distributed on the outer wall of the counterweight water tank near the bottom. Each leveling mechanism includes a connecting plate fixedly connected to the outer wall of the counterweight water tank. An adjusting screw threadedly connected to the connecting plate is installed through the connecting plate. The bottom end of the adjusting screw is fixedly connected to a support foot located below the connecting plate, and the top end of the adjusting screw is fixedly connected to a crossbar.

[0006] As a preferred technical solution of this utility model, a connecting mechanism is detachably installed on the outer wall of the telescopic support rod near the top, and two auxiliary support mechanisms are symmetrically installed on the outer wall of the connecting mechanism.

[0007] As a preferred technical solution of this utility model, the connecting mechanism includes a first connecting block and a second connecting block arranged symmetrically. Both ends of the first connecting block and the second connecting block are provided with mounting holes. The first connecting block and the second connecting block are connected to each other by bolts. The outer walls of the first connecting block and the second connecting block are each equipped with a hinge seat that cooperates with the auxiliary support mechanism.

[0008] As a preferred technical solution of this utility model, an annular limiting block is fixedly installed on the outer wall of the sleeve, and the inner walls of the first connecting block and the second connecting block are both provided with grooves that cooperate with the limiting block.

[0009] As a preferred technical solution of this utility model, the auxiliary support mechanism includes an outer tube, an adjusting rod is threadedly connected to the inside of the outer tube, a base plate is hinged to the bottom end of the outer tube, and an anchoring rod is installed through the base plate.

[0010] As a preferred technical solution of this utility model, a connecting seat located outside the through hole is fixedly installed at the top center of the counterweight water tank. The inner wall of the connecting seat and the bottom outer wall of the sleeve are both provided with mutually matching threads. A sealing gasket installed on the top of the counterweight water tank is provided on the inner side of the connecting seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This grapevine trellis, through the design of a sleeve, movable rod, piston, and through hole, allows water injected into the counterweight tank to enter the sleeve through the through hole during use. The piston then pushes the frame at the top of the movable rod upward, thus adjusting the height of the frame. After adjustment, maintaining the water pressure in the counterweight tank and sleeve keeps the frame at a fixed height, effectively preventing the frame from sliding down due to the increased weight of grape branches, leaves, and fruit, and ensuring stability after height adjustment. 2. This grapevine support frame, with its counterweight water tank, water inlet pipe, drain pipe, and valve, increases the weight of the counterweight water tank by adding water through the water inlet pipe, thereby improving the stability of the telescopic support rod and the frame. It can be used in both soft and hard soil. When it is necessary to move the grapevine, the water in the counterweight water tank can be drained by opening the valve on the drain pipe, which reduces the overall weight and makes it easier to move and transport. 3. This grapevine support frame, through the setting of connecting plates, adjusting screws and support legs, allows the position of the support legs to be adjusted by rotating the adjusting screws via the crossbar during use, so that the telescopic support rods and the frame body remain perpendicular to the ground, making it easy to adapt to uneven land in vineyards.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0015] like Figures 1-5 As shown, this embodiment proposes a grapevine trellis, including a frame body 6 and a telescopic support rod 1 installed at the bottom of the frame body 6. The telescopic support rod 1 includes a sleeve 11, a movable rod 12 slidably installed inside the sleeve 11, and a piston 13 slidably installed inside the sleeve 11 fixedly connected to the bottom end of the movable rod 12. A filter screen 14 is threadedly connected to the bottom inner wall of the sleeve 11. The filter screen 14 prevents mud and sand from entering the interior of the sleeve 11. Through the arrangement of the sleeve 11, movable rod 12, piston 13, and through hole 8, water injected into the counterweight water tank 21 enters the sleeve 11 through the through hole 8 during use. Inside the telescopic support rod 1, the piston 13 pushes the top of the frame 6 on the movable rod 12 to rise, thereby adjusting the height of the frame 6. After adjustment, maintaining the water pressure in the counterweight water tank 21 and the sleeve 11 keeps the frame 6 at a fixed height, effectively preventing the frame 6 from sliding down due to the increased weight of grape branches, leaves, and fruits, and ensuring stability after height adjustment. The counterweight mechanism 2 is detachably installed at the bottom of the telescopic support rod 1. The counterweight mechanism 2 includes a frustum-shaped counterweight water tank 21. A water inlet pipe 22 is installed through the top of the counterweight water tank 21, and a drain pipe 23 is installed on the side wall of the water inlet pipe 22 near the bottom. The water inlet pipe 22 and the drain pipe Valves 24 are installed in the middle of each of the 23 components; the top center of the counterweight water tank 21 has a through hole 8 that cooperates with the telescopic support rod 1. Through the arrangement of the counterweight water tank 21, water inlet pipe 22, drain pipe 23, and valves 24, water is added to the counterweight water tank 21 through the water inlet pipe 22 during use, increasing the weight of the counterweight water tank 21 and improving the stability of the telescopic support rod 1 and the frame 6. It can be used in both soft and hard soil. When transportation is required, opening the valve 24 on the drain pipe 23 drains the water from the counterweight water tank 21, reducing the overall weight and facilitating transportation and movement; multiple leveling mechanisms 3 evenly distribute... The leveling mechanism 3, located on the outer wall near the bottom of the counterweight water tank 21, includes a connecting plate 31 fixedly connected to the outer wall of the counterweight water tank 21. An adjusting screw 32 threadedly connected to the connecting plate 31 is installed through the connecting plate 31. A support foot 33 located below the connecting plate 31 is fixedly connected to the bottom end of the adjusting screw 32. A crossbar 34 is fixedly connected to the top end of the adjusting screw 32. Through the arrangement of the connecting plate 31, the adjusting screw 32, and the support foot 33, the adjusting screw 32 can be rotated through the crossbar 34 during use to adjust the position of the support foot 33, so that the telescopic support rod 1 and the frame 6 remain perpendicular to the ground, which is convenient for adapting to uneven land in the vineyard.

[0016] like Figure 1 and Figure 4 As a preferred embodiment, based on the above method, a connecting mechanism 5 is detachably installed on the outer wall of the telescopic support rod 1 near the top. Two auxiliary support mechanisms 4 are symmetrically installed on the outer wall of the connecting mechanism 5. It should be noted that the connecting mechanism 5 and the auxiliary support mechanisms 4 provide auxiliary support for the telescopic support rod 1 when there are many grapes, thereby preventing the telescopic support rod 1 and the frame 6 from tipping over.

[0017] like Figure 1 , Figure 2 and Figure 4 As a preferred embodiment, based on the above method, the connecting mechanism 5 further includes a first connecting block 501 and a second connecting block 502 symmetrically arranged. Both ends of the first connecting block 501 and the second connecting block 502 are provided with mounting holes 506. The first connecting block 501 and the second connecting block 502 are connected to each other by bolts 504. The outer walls of the first connecting block 501 and the second connecting block 502 are each provided with a hinge seat 503 that cooperates with the auxiliary support mechanism 4. The outer wall of the sleeve 11 is fixedly installed with an annular limiting block 10. The inner walls of the first connecting block 501 and the second connecting block 502 are each provided with a groove 505 that cooperates with the limiting block 10. It should be noted that during use, the mounting holes 506 on the first connecting block 501 and the second connecting block 502 should be aligned, and then the first connecting block 501 and the second connecting block 502 can be fixed to the outer wall of the sleeve 11 by passing the bolt 504 through the mounting holes 506. The setting of the limiting block 10 and the groove 505 can prevent the first connecting block 501 and the second connecting block 502 from sliding.

[0018] like Figure 1 and Figure 4 As a preferred embodiment, based on the above method, the auxiliary support mechanism 4 further includes an outer tube 401, an adjusting rod 402 threadedly connected to the inside of the outer tube 401, a base plate 403 hinged to the bottom end of the outer tube 401, and an anchoring rod 404 installed through the base plate 403. It should be noted that, during use, rotating the outer tube 401 can adjust the length of the adjusting rod 402 extending inside, thereby adjusting the overall length of the auxiliary support mechanism 4. The anchoring rod 404 and the base plate 403 facilitate the fixation of the bottom end of the auxiliary support mechanism 4.

[0019] like Figure 1 and Figure 3As shown, in a preferred embodiment, based on the above method, a connecting seat 9 located outside the through hole 8 is fixedly installed at the top center of the counterweight water tank 21. The inner wall of the connecting seat 9 and the bottom outer wall of the sleeve 11 are both provided with mating threads. A sealing gasket 7 is provided on the inner side of the connecting seat 9 and installed on the top of the counterweight water tank 21. It should be noted that the sealing gasket 7 improves the sealing performance between the sleeve 11 and the counterweight water tank 21, and the connecting seat 9 facilitates the installation and removal of the sleeve 11.

[0020] Specifically, the working principle of this grapevine trellis is as follows: Before use, the position of the support legs 33 is adjusted by rotating the adjusting screw 32 through the crossbar 34, so that the telescopic support rod 1 and the frame 6 are perpendicular to the ground. When in use, the valve 24 on the water inlet pipe 22 is opened to fill the counterweight water tank 21 with water. When the counterweight water tank 21 is full, water is continued to be added to the counterweight water tank 21 through the water inlet pipe 22. At this time, water will enter the interior of the sleeve 11 through the hole 8, pushing the piston 13 located at the bottom of the inner wall of the sleeve 11 to drive the movable rod 12 to rise, thereby driving the frame 6 to rise. When it rises to the required height, the water filling is stopped and the water supply is closed. The valve 24 on pipe 22 can fix the height of the frame 6. When it is necessary to lower the height of the frame 6, open the valve 24 on the drain pipe 23 to drain the water in the counterweight water tank 21, which will cause the piston 13 to drop, thereby lowering the height of the frame 6. When there are many grapes, the auxiliary support mechanism 4 can be installed on the outer wall of the sleeve 11 through the connecting mechanism 5. Then, rotate the outer pipe 401 to adjust the length of the adjusting rod 402 extending into it, and adjust the overall length of the auxiliary support mechanism 4 so that the base plate 403 is pressed against the ground to provide auxiliary support for the sleeve 11. At the same time, the anchor rod 404 can be driven into the soil to keep the base plate 403 stable.

[0021] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
