Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary frames, and more particularly to an auxiliary frame for cultivating and planting crops. Background Art

[0002] The tea tree is a shrub or small tree of the Theaceae family and the genus Camellia. Its young branches are hairless. Its leaves are leathery and oblong or oval. The leaves of the tea tree can be used to make tea (different from the oil tea tree), and its seeds can be used to extract oil. The tea tree has a fine texture and its wood can be used for carving. When planting tea trees, auxiliary brackets are needed to assist in fixing and supporting the tea trees.

[0003] A Chinese patent with authorization publication number CN217217653U discloses a tea tree planting auxiliary bracket. By rotating the turntable, the turntable can drive the screw rod to rotate, so that the screw rod drives the nut threadedly connected thereto to adjust up and down, so that the up and down adjustment of the nut drives the sliders at both ends of the connecting plate to slide and adjust on the surface of the slide rail, so that the sliding adjustment of the slider drives the angle adjustment of the connecting rod, and the connecting rod drives the support plate to rotate and adjust, so that the support plate can support the entire device, making the installation and adjustment of the entire device simple.

[0004] Although the tea tree planting auxiliary support can support the tea tree, in actual use, the support for the tea tree is relatively simple. The existing equipment not only has a poor fixing effect on the tea tree, but is mostly fixed equipment. As the tea tree gradually grows bigger and thicker, the existing equipment cannot meet the diameter of the grown tea tree, thereby limiting the growth of the tea tree and affecting its normal growth.

The closing mechanism includes a sleeve 10 fixedly installed on the rear end of the outer surface of the fixed crescent ring 2, an inner cavity 11 is opened inside the fixed crescent ring 2, the inner cavity 11 and the sleeve 10 are communicated with each other, the rear end surface of the sleeve 10 is spirally connected with a threaded rod 2 13, the rear end of the threaded rod 2 13 is fixedly installed with a handle 2, the interior of the sleeve 10 is slidably connected with a piston plate 12, one end of the threaded rod 2 13 extends to the interior of the sleeve 10 and is fixedly connected to the piston plate 12, one end of the inner cavity 11 is slidably connected with an extension ring 15, and the other end of the inner cavity 11 is slidably connected with an extension ring 2 16, and the ends of the extension ring 15 and the extension ring 2 16 are correspondingly opened with slots 17, and one side of the slot 17 is fixedly installed with an insertion rod 18.

[0032] When it is necessary to set up an auxiliary frame for precious tea trees, first, the combination of the three groups of first-level supporting legs 4 and the second-level supporting legs 5 is adaptively adjusted according to the terrain, and then the handle 1 9 is twisted to rotate the threaded rod 1 8, and then the adjusted second-level supporting leg 5 is fixed, so that the fixed crescent ring 2 is horizontally sleeved on the tea tree, and then the handle 2 14 on the threaded rod 2 13 is twisted to rotate the threaded rod 2 13, and the threaded rod 2 13 will continue to advance inside the casing 10 and push the piston plate 12 to move inside the casing 10, so that the gas inside the casing 10 enters the inner cavity 11, and the extension ring 15 and the extension ring 2 16 at both ends of the inner cavity 11 are extended from the inner cavity 11, and the insertion rod 18 on the extension ring 2 16 is inserted into the slot 17 on the extension ring 15, and the insertion rod 18 on the extension ring 15 is inserted into the slot 17 on the extension ring 2 16 to complete the initial support of the tea tree.

[0035] When the extension ring 15 and the extension ring 2 16 are displaced, they are displaced together with a group of transmission rings 19, and the support block 20 on the transmission is displaced synchronously. The various groups of components on the support block 20 are displaced along with the displacement of the support block 20, and the gear 23 on the threaded rod 3 21 is meshed with the rack 22 on the fixed crescent ring 2, so the threaded rod 3 21 will rotate, and the threaded sleeve 24 connected to the outer surface of the threaded rod 3 21 with a spiral transmission will drive the sliding rod 25 to displace, and the sliding rod 25 makes the roller 31 displace toward the tea tree through the push plate 26, the sleeve 27, the transmission column 28 and the support member 30, and is tightly attached to the tea tree, and this group of rollers 31 will follow the transmission ring 19 to move to the front side of the tea tree to support it.

[0036] The fixing mechanism 2 includes a supporting block 2 32 fixedly installed on the left side of the upper end surface of the crescent ring 2, a sliding rod 2 33 is slidably connected to the front end of the supporting block 2 32, a push plate 2 34 is fixedly installed to the front end of the slide rod 2 33, a sleeve 2 35 is fixedly installed to the front end of the push plate 2 34, a transmission column 2 36 is slidably connected to the front end of the sleeve 2 35, a support member 2 38 is fixedly installed to the front end of the transmission column 2 36, a spring 2 37 is fixedly installed between the support member 2 38 and the push plate 2 34, and the support member 2 38 is fixedly installed to the spring 2 37.

[0039] When the two groups of rollers 2 39 are synchronously displaced toward the tea tree, they will respectively carry a group of sliding shafts 44 for displacement. A sliding sleeve 45 is slidably connected between the two groups of sliding shafts 44. When the sliding shafts 44 are displaced toward the tea tree, they will slide inside the sliding sleeve 45 and drive the sliding sleeve 45 to displace toward the tea tree. The rollers 3 47 on the sliding sleeve 45 are synchronously in close contact with the tea tree to support the rear of the tea tree. Secondly, the combination of the push plate 1 26, the sleeve 1 27, the transmission column 1 28, the spring 1 29 and the push plate 2 34, the sleeve 2 35, the transmission column 2 36 and the spring 2 37 can be compressed as the tea tree gradually grows thicker, thereby not affecting it.

[0040] The fixing mechanism 1 and the fixing mechanism 2 are respectively provided with two groups, and are symmetrically arranged. The two groups of the fixing mechanism 2 are arranged on the inner side of the fixing mechanism 1, and the fixing mechanism 3 is arranged between the two groups of the fixing mechanism 2.

[0041] Instructions for use: When it is necessary to set up an auxiliary frame for precious tea trees, first, the combination of the three groups of first-level supporting legs 4 and the second-level supporting legs 5 is adaptively adjusted according to the terrain, and then the handle 1 9 is twisted to rotate the threaded rod 1 8, and then the adjusted second-level supporting legs 5 are fixed, so that the fixed crescent ring 2 is horizontally sleeved on the tea tree, and then the handle 2 14 on the threaded rod 2 13 is twisted to rotate the threaded rod 2 13, and the threaded rod 2 13 will continue to advance inside the casing 10, and push the piston plate 12 to move inside the casing 10, so that the gas inside the casing 10 enters the inner cavity 11, and the extension ring 15 and the extension ring 2 16 at both ends of the inner cavity 11 are extended from the inner cavity 11, and the insertion rod 18 on the extension ring 2 16 will be inserted into the slot 17 on the extension ring 15, and the insertion rod 18 on the extension ring 15 will be inserted into the slot 17 on the extension ring 2 16 to complete the initial support of the tea tree.

[0042] When the extension ring 15 and the extension ring 2 16 are displaced, they are displaced together with a group of transmission rings 19, and the support block 20 on the transmission is displaced synchronously. The various groups of components on the support block 20 are displaced along with the displacement of the support block 20, and the gear 23 on the threaded rod 3 21 is meshed with the rack 22 on the fixed crescent ring 2, so the threaded rod 3 21 will rotate, and the threaded sleeve 24 connected to the outer surface of the threaded rod 3 21 with a spiral transmission will drive the sliding rod 25 to displace, and the sliding rod 25 makes the roller 31 displace toward the tea tree through the push plate 26, the sleeve 27, the transmission column 28 and the support member 30, and is tightly attached to the tea tree, and this group of rollers 31 will follow the transmission ring 19 to move to the front side of the tea tree to support it.
