Description

Technical Field

[0001] The utility model relates to the technical field of seedling cultivation devices, in particular to a seedling sunshade device. Background Art

[0002] In the early stages of growth, seedlings often cannot withstand strong direct sunlight. Excessive light will inhibit their growth and even cause leaf burns. Shading can effectively reduce light intensity, provide a more suitable lighting environment, and contribute to the healthy growth of seedlings. However, photosynthesis is an indispensable physiological process for plant growth, and it requires sufficient light to promote plant growth and development. Therefore, when the light conditions in the environment are no longer strong enough to cause damage to the seedlings, it is necessary to remove the shading to allow the seedlings to receive the appropriate amount of sunlight for photosynthesis.

[0003] The document with prior art publication number CN209594403U provides a garden tree seedling sunshade device. The device is equipped with rollers to facilitate the staff to move the device. At the same time, a lifting mechanism is provided to facilitate the staff to adjust the height of the sunshade. It effectively solves the problem that the height of the currently used sunshade is fixed, and as the tree grows during use, the height of the sunshade cannot meet the requirements.

[0004] In the above prior art, the sunshade cloth is fixedly connected to the sunshade awning. When light is needed, the sunshade device can only be removed to cancel the sunshade effect. Although this method is feasible, it may not be flexible in operation, especially in occasions where frequent adjustment of sunshade and light conditions is required. Moreover, removing the sunshade device will temporarily use other space. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a sapling sunshade device, aiming to solve the problems raised by the above-mentioned background technology.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a seedling sunshade device, including a sunshade cloth and a shell, the shell is internally rotatably connected to two shafts, two gears are respectively provided on the two shafts, and the gears on the two shafts are respectively meshed and connected; two sides of the shell are respectively connected to two groove bodies, the groove bodies are inclined downward at one end away from the shell, and a moving rod is slidably connected between the two corresponding groove bodies, the number of the sunshade cloths is two, one end of the two sunshade cloths are respectively fixedly connected to the two shafts, and the other ends of the two sunshade cloths are respectively fixedly connected to the moving rods, the end of the groove body away from the shell is connected to a supporting leg, and one end of one of the shafts extends out of the shell and is connected to a crank.

[0007] Preferably, a mounting plate is provided at the lower end of the supporting leg, and a mounting hole is provided on the mounting plate.

[0008] Preferably, triangular reinforcing ribs are welded between the mounting plate and the supporting legs.

[0009] Preferably, a support rod is welded between the support leg and the trough body.

[0010] Preferably, the number of the cranks is two, and both ends of one of the rotating shafts extend out of the shell and are connected to the two cranks.

[0011] Preferably, two ends of the moving rod are respectively connected with sliding blocks, and the sliding blocks extend into the sliding grooves of the groove body and are slidably connected with the groove body.

[0012] Preferably, the upper surface and the lower surface of the sliding block are rotatably connected with rollers respectively, and the rollers are in contact with the inner wall of the sliding groove.

[0013] Beneficial Effects

[0014] The utility model provides a sapling sunshade device. During the use of the utility model, when shading is needed, the crank is turned in a first direction, and the rotation of the crank drives the rotating shaft connected thereto to rotate, and the rotating shaft drives the gear installed thereon to rotate. As shown in the figure, the gears on the two rotating shafts are meshed with each other. Therefore, when the crank drives the rotating shaft connected thereto to rotate, the other rotating shaft performs synchronous movement in the opposite direction. The rotation of the two rotating shafts releases the sunshade cloth wrapped around themselves. Due to the inclined design of the groove body and the action of gravity on the moving rod, the moving rod has a tendency to move away from the shell. When the sunshade cloth is released, the moving rod slides between two corresponding groove bodies and moves away from the shell. At this time, the sunshade cloth gradually extends out of the shell and unfolds, providing sunshade for the saplings located below.

[0015] When the shading effect on the saplings needs to be cancelled, the crank is turned in the second direction, the crank drives the two shafts to rotate, and the sunshade cloth is rolled up, so that the sunshade cloth is stored in the shell, and the shading effect on the saplings is cancelled.

[0016] The deployment and storage of the sunshade cloth can be controlled by turning the crank, so as to provide shading effect for the seedlings and cancel the shading effect. There is no need to move the sunshade device itself. The operation is convenient and it is easy to switch between the shading state and the non-shading state of the seedlings. When the light is strong, the seedlings are shaded. When the light is weak, the shading of the seedlings is canceled to allow the seedlings to photosynthesize and promote their growth.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a sapling sunshade device, including a sunshade cloth 1 and a shell 2. The shell 2 has two internal rotationally connected shafts 3, and two gears 4 are respectively arranged on the two rotation shafts 3. The gears 4 on the two rotation shafts 3 are respectively meshed and connected; two sides of the shell 2 are respectively connected to two slots 5, and a slide groove is provided on the slot 5. The slot 5 is inclined downward at one end away from the shell 2, and a moving rod 8 is slidably connected between the two corresponding slots 5, wherein the moving rod 8 extends out of the slide groove of the slot 5 and is slidably connected with the slide groove. The number of the sunshade cloths 1 is two, and one end of the two sunshade cloths 1 is respectively fixedly connected to the two rotation shafts 3, and slot holes for the sunshade cloths 1 to extend are arranged on both sides of the shell 2. The sunshade cloth 1 extends out due to the shell 2, and the other ends of the two sunshade cloths 1 are respectively fixedly connected to the moving rod 8, and the slot 5 is connected to a supporting leg 6 at one end away from the shell 2, and one end of the rotation shaft 3 extends out of the shell 2 and is connected to a crank 7.

[0024] When in use, the sunshade device is placed above the sapling, and the four supporting legs 6 are fixed to the ground. In the initial state, the two sunshade cloths 1 are respectively wound around the rotating shaft 3. When sunshade is needed, the crank 7 is turned in the first direction, and the rotation of the crank 7 drives the rotating shaft 3 connected thereto to rotate, and the rotating shaft 3 drives the gear 4 installed thereon to rotate. Figure 2As shown, the gears 4 on the two rotating shafts 3 are meshed with each other, so when the crank 7 drives the rotating shaft 3 connected thereto to rotate, the other rotating shaft 3 performs a synchronous movement in the opposite direction. The rotation of the two rotating shafts 3 releases the sunshade cloth 1 wrapped around themselves. Due to the inclined design of the groove body 5 and the action of gravity on the moving rod 8, the moving rod 8 has a tendency to move away from the shell 2. When the sunshade cloth 1 is released, the moving rod 8 slides between the two corresponding groove bodies 1 and moves away from the shell 2. At this time, the sunshade cloth 1 gradually extends out of the shell 2 and unfolds, providing shading for the saplings located below.

[0025] When the shading effect on the saplings needs to be cancelled, the crank 7 is turned in the second direction, and the crank 7 drives the two shafts 3 to rotate, so as to roll up the sunshade cloth 1, prompting the sunshade cloth 1 to be stored in the shell 2, and canceling the shading effect on the saplings.

[0026] The unfolding and folding of the sunshade cloth 1 can be controlled by turning the crank 7, so as to provide shading effect for the seedlings and cancel the shading effect. There is no need to move the sunshade device itself. The operation is convenient and it is easy to frequently switch between the shading state and the non-shading state of the seedlings. When the light is strong, the seedlings are shaded. When the light is weak, the shading of the seedlings is cancelled, so that the seedlings can photosynthesize and promote their growth.

[0027] Specifically, a mounting plate 9 is provided at the lower end of the support leg 6, and a mounting hole 10 is provided on the mounting plate 9. During installation, a mounting nail is used to pass through the mounting plate 9 to fix the mounting plate 9 on the ground.

[0028] Specifically, a triangular reinforcing rib 11 is welded between the mounting plate 9 and the supporting leg 6. The setting of the reinforcing rib 11 can effectively improve the stability between the mounting plate 9 and the supporting leg 6, thereby improving the structural stability of the sunshade device itself.

[0029] Specifically, a support rod 12 is welded between the support leg 6 and the trough body 5. The setting of the support rod 12 can effectively improve the structural stability between the support leg 6 and the trough body 5, thereby effectively improving the structural stability of the sunshade device itself.

[0030] Specifically, there are two cranks 7, and both ends of one of the rotating shafts 3 extend out of the housing 2 and are connected to the two cranks 7. Two cranks 7 are designed so that the operator can unfold and retract the sunshade cloth 1 on both sides of the sunshade device, providing convenience for the operator's operation.

[0031] Specifically, two ends of the moving rod 8 are respectively connected with sliders 13, and the sliders 13 extend into the slide grooves of the slot body 5 and are slidably connected with the slot body 5. The setting of the sliders 13 is used to improve the stability of the moving rod 8 sliding relative to the slot body 5.

[0032] Specifically, the upper and lower surfaces of the slider 13 are rotatably connected to rollers 14, respectively, and the rollers 14 are in contact with the inner wall of the slide groove. During the movement of the moving rod 8, the slider 13 slides in the slide groove of the groove body 5, and the rollers 14 roll at the same time. The setting of the rollers 14 is used to reduce the friction between the slider 13 and the slide groove, so as to avoid jamming during the movement of the moving rod 8, thereby causing the sunshade 1 to fail to unfold or incompletely unfold.

[0033] It should be noted that, in order to ensure the smooth sliding of the moving rod 8, the moving rod 8 itself is made of solid stainless steel. In addition, in this embodiment, the inclination angle of the groove body 5 is greater than 10 degrees.

[0034] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
