Description

Technical Field

[0001] This utility model relates to the field of tomato planting technology, and in particular to a support device for tomato planting. Background Technology

[0002] Tomatoes are annual herbaceous plants belonging to the Solanaceae family and the Solanum genus. The plants can reach up to 2 meters in height. Genetically modified tomatoes are bright red, have firm fruit, and are less prone to cracking. However, the stems are prone to lodging. The leaves are pinnately compound with a wedge-shaped, somewhat oblique base and irregular serrations. The corolla is radiate, yellow, with narrow, oblong lobes. The berries are oblate or nearly spherical, fleshy and juicy, orange-yellow or bright red, with a smooth surface. Flowering and fruiting occur in summer and autumn. The seeds are yellow and covered with soft hairs. Tomato cultivation requires support equipment for planting.

[0003] Traditional support techniques often employ a single-stem pruning cultivation model, using bamboo poles, metal poles, or special supports to construct a guiding structure. Flexible materials such as cloth strips and ropes are used to fix the main stem, guiding the plant to grow along a predetermined trajectory, optimizing the efficiency of canopy light energy utilization, and preventing the risk of disease caused by the fruit contacting the ground due to stem creep.

[0004] However, as the stems thicken, traditional binding materials require manual adjustment of tightness multiple times. Operational errors can easily lead to mechanical damage to the stem epidermis or fixation failure. Especially in high temperature and high humidity environments, excessive binding may cause compression of the vascular bundles of the stem, affecting the efficiency of water and nutrient transport. Secondly, existing supports mostly adopt a fixed design, which cannot match the dynamic development needs of indeterminate tomato varieties, resulting in insufficient support height or excessive restraint in the middle and late stages of growth, which in turn induces an imbalance of apical dominance and abnormal development of lateral branches. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology where the supporting equipment is not convenient for supporting and guiding tomato stems at different growth stages, and the use of ropes or cloth strips for fixing can easily damage the stems. Therefore, this invention proposes a supporting equipment for tomato planting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tomato planting support device includes a fixed frame and at least three sets of lead screws mounted on the fixed frame. The fixed frame is provided with an adjusting component, which causes the lead screws to move vertically when the adjusting component rotates. A limiting sleeve is slidably connected to the lead screws. A positioning plate and an elastic sheet are fixedly connected to the limiting sleeve. The end of the elastic sheet away from the limiting sleeve is engaged with the positioning plate, and the elastic sheet and the limiting sleeve form a clamping space to limit the tomato stem.

[0008] For adjusting the lateral and longitudinal positions of the lead screw, preferably, the adjusting component includes a movable seat slidably connected to a fixed frame, a threaded sleeve rotatably connected to the movable seat, and the lead screw threadedly connected to the threaded sleeve.

[0009] To facilitate the rotation of the threaded sleeve, a bearing is further fixedly fitted onto the threaded sleeve, and the outer ring of the bearing is fixedly connected to the movable seat.

[0010] To prevent the lead screw from rotating, preferably, the movable seat has a limiting hole, and the lead screw has a groove that matches the limiting hole, the groove being slidably connected within the limiting hole.

[0011] To improve the limiting effect of the elastic sheet, the elastic sheet is further made arc-shaped, and a tough groove is formed on the elastic sheet.

[0012] In order to adjust the vertical position of the limiting sleeve and improve the limiting of different parts of the tomato stem, the limiting sleeve is further provided with a screw threaded on it, one end of which abuts against the lead screw.

[0013] To facilitate the replacement of insertion rods of different lengths and to achieve height adjustment of the fixing frame, preferably, the fixing frame consists of insertion rods and a support plate, and the support plate is fixedly installed on the insertion rods by bolts.

[0014] Compared with the prior art, this utility model provides a support device for tomato planting, which has the following beneficial effects:

[0015] 1. This tomato planting support equipment, through the setting of the adjustment component, can vertically adjust a single screw by rotating the threaded sleeve, so as to guide and support tomato stalks of different heights and growth stages. Furthermore, by moving the position of the moving seat laterally, the spacing between the screws can be adjusted, so that the support equipment can adapt to tomato stalks with different planting densities.

[0016] 2. This tomato planting support device can fix the limiting sleeve by setting screws, thereby improving the flexibility of the limiting sleeve.

[0017] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model can support tomato stems at different growth stages by adjusting the height of the lead screw through the adjusting component. Secondly, the clamping space composed of the elastic sheet and the limiting sleeve can effectively avoid damage to the stem surface caused by traditional binding methods, thereby improving the support effect of tomato stems.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example:

[0027] Reference Figures 1-5A tomato planting support device includes a fixed frame 1, which consists of a rod and a support plate. The support plate is fixedly mounted on the rod by bolts. The bolt fixing method facilitates the replacement of rods of different lengths, increases the guiding distance of the fixed frame 1, and thus expands its application range. It also includes at least three sets of lead screws 4, the number of which is three to six, preferably six, for supporting and guiding multiple tomato stems. The fixed frame 1 is equipped with an adjusting component. When the adjusting component rotates, the lead screws 4 move vertically and slide on the limiting sleeve 5. The limiting sleeve 5 is fixedly connected to a positioning plate 51 and an elastic sheet 52. The end of the elastic sheet 52 away from the limiting sleeve 5 is engaged with the positioning plate 51. The elastic sheet 52 and the limiting sleeve 5 form a clamping space to limit the tomato stem. The elastic sheet 52 is arc-shaped and has a tough groove, which plays a role in limiting the tomato stem and avoiding damage to the stem skin caused by clamping.

[0028] Specifically, by adjusting the height of the lead screw 4, the tomato stems at different growth stages can be supported. Secondly, the clamping space formed by the elastic sheet 52 and the limiting sleeve 5 can effectively avoid damage to the stem surface caused by traditional binding methods, thereby improving the support effect of the tomato stems.

[0029] The adjusting component includes a movable seat 2 slidably connected to a fixed frame 1, a threaded sleeve 3 rotatably connected to the movable seat 2, a lead screw 4 threadedly connected to the threaded sleeve 3, a bearing 31 fixedly sleeved on the threaded sleeve 3, the outer ring of the bearing 31 being fixedly connected to the movable seat 2, a limiting hole 6 being provided on the movable seat 2, and a groove 7 being provided on the lead screw 4 that mates with the limiting hole 6, the groove 7 being slidably connected to the limiting hole 6 and used to limit the lead screw 4.

[0030] Specifically, by adjusting the screw sleeve 3, the individual screw 4 can be vertically adjusted, thus guiding and supporting tomato stems of different heights and growth stages. Furthermore, by moving the position of the moving seat 2 laterally, the spacing between the screws 4 can be adjusted, allowing the support device to adapt to tomato stems with different planting densities.

[0031] The limiting sleeve 5 is threaded with a screw 53, one end of which abuts against the lead screw 4.

[0032] Specifically, the screw 53 can be used to fix the limiting sleeve 5, thereby improving the flexibility of the limiting sleeve 5 in use.

[0033] Working principle: When fixing tomato stems, the user deforms the elastic plate 52 by moving it, and then places the stem into the clamping space formed by the positioning plate 51 and the elastic plate 52. The elastic plate 52 automatically resets due to its material memory properties, forming a wrap-around support structure. This avoids damage to the stem skin caused by traditional binding methods, disperses the radial pressure on the stem through distributed contact surfaces, and locks the limiting sleeve 5 with screws 53, allowing the limiting sleeve 5 to slide freely along the axial direction of the screw 4. This enables vertical adjustment of the clamping point, enhances the bending stiffness of tall plants or stems during the fruiting period, and is suitable for the full-cycle cultivation needs of indeterminate varieties.

[0034] As the tomato stalks continue to grow, the user drives the screw 4 to move within the moving seat 2 by rotating the threaded sleeve 3. The extension length of the screw 4 can be finely adjusted periodically to ensure that the clamping point always matches the changes in the stalk's center of gravity, maintaining the vertical growth trajectory. Combined with the sliding adjustment of the limiting sleeve 5, a three-dimensional spatial adjustment system is formed, effectively coping with the impact of dynamic loads such as wind load and fruit weight on the stalk's posture. Compared with the traditional rigid support structure, this system organically combines mechanical limiting with a growth adaptive mechanism, improving the applicability of the support equipment in the entire growth period and in multi-variety cultivation scenarios.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
