Description

Technical Field

[0001] The utility model relates to the technical field related to tree experiments, in particular to a multifunctional fixing box used for agricultural planting experiments. Background Art

[0002] In order to conduct a comprehensive analysis of different plants in agricultural planting, it is usually necessary to cut off a section of the grown plants or trees for experiments. In order to improve the accuracy of the experimental data, it is necessary to cut off multiple branches for comparative experiments. Therefore, the experimental branches are fixed in the corresponding fixed boxes. For example, the publication number CN211477565U is an adjustable grid for fixing plants in a wind tunnel experiment, including a grid tray, four grid vertical brackets, four grid horizontal brackets, a number of transverse adjustment rods and longitudinal adjustment rods. By adjusting the grid structure to accommodate experimental flower pots of common sizes, the experimental plants are fixed, providing a guarantee for plant wind tunnel experiments. However, the adjustable grid for fixing plants in wind tunnel experiments still has the following disadvantages in actual use:

[0003] Although the above-mentioned grid can fix the tree branches, its functions are not diverse enough. It is impossible to simulate different states by blowing air during the experiment, which leads to relatively simple subsequent experimental data. The experiment on the tree branches is not comprehensive enough. In view of the above problems, it is urgently necessary to carry out innovative design based on the original fixing box. Utility Model Content

[0004] The purpose of the utility model is to provide a multifunctional fixing box for agricultural planting experiments, so as to solve the problem that the functions of the above-mentioned background technology are not diversified enough and different states cannot be simulated by blowing air during the experiment, resulting in relatively single subsequent experimental data and insufficient comprehensiveness of the experiment on tree branches.

[0005] To achieve the above object, the utility model provides the following technical solutions: a multifunctional fixing box for agricultural planting experiments, provided with a box body, a fixing rod is fixed to the inner bottom surface of the box body, and a connecting plate is fixed to the side of the fixing rod at equal angles through a rod, and the cross section of the connecting plate is an arc;

[0006] It includes: a limiting component, which is movably arranged on the top of the fixing rod, and the limiting component and the connecting plate cooperate with each other to fix the tree trunk;

[0007] The motor is installed at the top edge of the box body by bolts, the output shaft of the motor is connected to the connecting shaft, and the outer fixed sleeve of the connecting shaft is provided with a gear;

[0008] The fan blade is fixedly mounted on the bottom of the connecting shaft, and a protective cover is sleeved on the outer side of the fan blade, and the protective cover is fixed to the side of the box body;

[0009] The blowing component is movably arranged on the inner wall of the box body. The blowing component is used to simulate the blowing state during the tree trunk experiment, and the gas of the blowing component comes from the gas generated by the rotation of the fan blades.

[0010] Preferably, the limiting assembly includes a limiting belt, and one end of the limiting belt is adhered to the edge of the connecting plate, and the other end of the limiting belt is adhered to the side of the movable rod. At the same time, the movable rod and the fixed rod form a rotating structure through a damping member. After the limiting belt is tightened, the branch can be tightly fixed on the inner side of the connecting plate.

[0011] Preferably, the gear and the tooth block are meshingly connected, and the tooth block is fixed at equal angles on the outside of the movable ring. The movable ring can be driven to rotate through the meshing transmission between the gear and the tooth block.

[0012] Preferably, a limiting ring is sleeved on the outer side of the movable ring, and the limiting ring is fixed to the inner wall of the box body, and the upper and lower sides of the movable ring slide in contact with the inner wall of the limiting ring, and when the movable ring rotates, it can rotate inside the limiting ring to maintain stability.

[0013] Preferably, the blowing assembly includes an air nozzle, and the air nozzle is arranged at an equal angle on the inner side of the movable ring, and gas can be discharged from the air nozzle and blown onto the tree branches to simulate wind blowing.

[0014] Preferably, a fixed cavity is opened inside the movable ring, and the cross-section of the fixed cavity is an inverted "U"-shaped structure. After the gas enters the fixed cavity, it can be discharged from the air nozzle, and the gas can be discharged in a rotational manner.

[0015] Preferably, the fixed cavity is interconnected with the protective cover through an air pipe, and the air pipe is fixed between the limiting ring and the protective cover, and the gas generated by the rotation of the fan blades can be transmitted from the air pipe to the fixed cavity.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the multifunctional fixing box for agricultural planting experiments has diversified functions. During the experiment, the wind can be blown onto the branches to simulate experiments in different states, thereby improving the diversity of data and the comprehensiveness of the branch experiment. The specific contents are as follows:

[0017] 1. Turn the movable rod to reel in the limit belt, so that the limit belt can be pulled to fit closely with the branch, so that the branch is fixed between the limit belt and the connecting plate to ensure stability during the test and prevent the branch from falling during subsequent wind blowing. When the branch needs to be removed, turn the movable rod in the opposite direction to release the reeling of the limit belt, so that the limit belt is in a relaxed state and the branch can be taken out;

[0018] 2. The meshing transmission between the gear and the tooth block drives the movable ring to rotate inside the limit ring, which can prevent gas leakage on the one hand, and on the other hand, when the subsequent gas is discharged from the air nozzle, it can be evenly blown onto the branches by rotating;

[0019] 3. The wind generated by the rotation of the fan blades enters the protective cover, and is then transmitted to the fixed cavity through the air pipe, and finally blows onto the branches from the air nozzle. Therefore, while the fixed box is experimenting on the branches, it can also simulate different states by blowing air. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] 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.

[0028] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0029] Embodiment 1: In order to solve the problems existing in the prior art, this embodiment adopts the following technical scheme: a multifunctional fixing box for agricultural planting experiments, which is provided with a box body 1, a fixing rod 2 is fixed to the inner bottom surface of the box body 1, and a connecting plate 3 is fixed to the side of the fixing rod 2 at an equal angle through a rod, and the cross-section of the connecting plate 3 is an arc; it includes: a limit assembly, which is movably arranged on the top of the fixing rod 2, and the limit assembly and the connecting plate 3 cooperate with each other to fix the trunk; a motor 6, which is installed at the top edge of the box body 1 by bolts, the output shaft of the motor 6 is connected to the connecting shaft 7, and the outer fixed sleeve of the connecting shaft 7 is provided with a gear 8; a fan blade 12, which is fixedly installed at the bottom of the connecting shaft 7, and the outer sleeve of the fan blade 12 is provided with a protective cover 13, and the protective cover 13 is fixed to the side of the box body 1; a blowing assembly, which is movably arranged on the inner wall of the box body 1, the blowing assembly is used to simulate the blowing state during the tree trunk experiment, and the gas of the blowing assembly comes from the gas generated by the rotation of the fan blade 12.

[0030] The existing fixing box is not convenient for fixing branches, and branches are easy to fall off from the fixing structure during the experiment. Figure 1-Figure 2 and Figure 4 As shown, the limiting assembly includes a limiting belt 4, and one end of the limiting belt 4 is adhered to the edge of the connecting plate 3, and the other end of the limiting belt 4 is adhered to the side of the movable rod 5, and the movable rod 5 and the fixed rod 2 form a rotating structure through a damping member; first, the branch sample to be tested is placed between the connecting plate 3 and the limiting belt 4, and then the movable rod 5 is rotated to achieve the winding of the limiting belt 4, so that the limiting belt 4 can be pulled to fit tightly with the branch, so that the branch is fixed between the limiting belt 4 and the connecting plate 3, so as to ensure the stability during the test, and also to prevent the branch from falling during subsequent blowing. When the branch needs to be removed, the movable rod 5 is rotated in the opposite direction to release the winding of the limiting belt 4, so that the limiting belt 4 is in a relaxed state and the branch can be taken out;

[0031] Embodiment 2: The existing fixing box has a relatively simple function, so the experiment on the tree branches is not comprehensive enough. Therefore, this embodiment adopts the following technical solutions, such as Figure 1 , Figure 3 and Figure 6 As shown, the gear 8 and the tooth block 10 are meshingly connected, and the tooth block 10 is fixed at an equal angle on the outside of the movable ring 9; a limiting ring 11 is sleeved on the outside of the movable ring 9, and the limiting ring 11 is fixed to the inner wall of the box body 1, and the upper and lower sides of the movable ring 9 are fitted and slid with the inner wall of the limiting ring 11; when the motor 6 drives the gear 8 to rotate through the connecting shaft 7, the movable ring 9 can be driven to rotate inside the limiting ring 11 through the meshing transmission between the gear 8 and the tooth block 10. Since the movable ring 9 can rotate closely inside the limiting ring 11, gas leakage can be prevented. At the same time, when the subsequent gas is discharged from the air nozzle 16, it can be evenly blown onto the branches by rotation;

[0032] Embodiment 3: The existing fixing box cannot simulate different states of branches by blowing air to conduct experiments. Therefore, this embodiment adopts the following technical solutions, such as Figure 2-Figure 3 and Figure 5 As shown, the blowing assembly includes an air nozzle 16, and the air nozzle 16 is at an equal angle on the inner side of the movable ring 9; a fixed cavity 15 is opened inside the movable ring 9, and the cross-section of the fixed cavity 15 is an inverted "U"-shaped structure; the fixed cavity 15 is interconnected with the protective cover 13 through the air pipe 14, and the air pipe 14 is fixed between the limit ring 11 and the protective cover 13; when the connecting shaft 7 rotates, the fan blades 12 can be driven to rotate synchronously, and then the generated wind force enters the protective cover 13, and then is transmitted to the fixed cavity 15 through the air pipe 14, and finally can be blown from the air nozzle 16 to the tree branches. Therefore, while the fixed box is experimenting on the tree branches, it can also simulate different states by blowing air, thereby improving the diversification of the device functions.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
