Description

Technical Field

[0001] The invention relates to the field of environmental science and technology, and in particular to a wind and sand blowing structure for simulating a plant's resistance to a wind and sand environment. Background Art

[0002] Whether it is the seaside or the desert, sandstorm disasters are rampant. Every time a strong wind blows, sand particles fly with the wind. The stronger the wind, the stronger the impact of the sand. Wherever the sand goes, the fields are buried, and towns and villages are turned into ruins. To resist the attacks of sandstorm disasters, shelterbelts must be built to weaken the power of wind and sand. Before building shelterbelts, it is necessary to simulate the wind and sand environment for plants to resist, and test plants that can effectively withstand wind and sand in a wind and sand environment.

[0003] Generally speaking, when simulating the environment in which plants resist wind and sand, a wind and sand blowing structure is used to blow sand to the surface of the plants. However, the existing wind and sand blowing structure easily causes sand to agglomerate and become blocked, making the simulation of the environment in which plants resist wind and sand impossible, thereby reducing the efficiency of the simulation.

[0004] In summary, how to solve the problem of sand clumping and clogging that prevents plant resistance to wind and sand environment simulation has become a technical challenge that technicians in this field urgently need to solve. Therefore, it is necessary to propose a wind and sand blowing structure for plant resistance to wind and sand environment simulation. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a wind and sand blowing structure for simulating plant resistance to wind and sand environment. The driving member drives the transmission rod and the first connecting rod to rotate, driving the pushing plate to push the sand out of the discharge port. The vibration plate vibrates back and forth to scatter the sand, thereby reducing the agglomeration and blockage of sand in the storage box and improving the efficiency of simulating plant resistance to wind and sand environment.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a wind-blown sand blowing structure for simulating a plant's resistance to a wind-blown sand environment, comprising a storage box and a blowing box, wherein the bottom of the storage box is detachably connected to the top of the blowing box; a feed port is formed at the top of the storage box, and a discharge port is formed at the bottom of the storage box; a guide tube is fixedly connected to the discharge port, and the end of the guide tube, which is remote from the discharge port, passes through the blowing box and extends into the interior of the blowing box;

[0007] A temporary storage component for temporarily storing sand is provided in the blowing box, and the temporary storage component is communicated with an end of the guide pipe away from the discharge port.

[0008] A pushing component for pushing sand is provided in the storage box, and a vibration component for vibrating the sand is provided on one side of the pushing component.

[0009] A controller is fixedly connected to the outer side wall of the storage box.

[0010] A wind component for blowing sand and a bearing component for bearing plants are arranged in the blowing box.

[0011] The pushing assembly includes a driving member, and a controller is used to control the operation of the driving member. The driving member is fixedly connected to the inner wall of the storage box. The output shaft of the driving member is fixedly connected to a transmission rod. The end of the transmission rod away from the driving member is hinged to a first connecting rod, and the end of the first connecting rod away from the transmission rod is hinged to a pushing plate.

[0012] A limiting frame is fixedly connected in the storage box, and the pushing plate is located in the limiting frame and slidably matched with the inner wall of the limiting frame.

[0013] The technical principle of the above solution is as follows: sand is added through the feed port, and a drive member drives the transmission rod to rotate. The rotation of the transmission rod drives the push plate to reciprocate, pushing the sand out of the discharge port. The reciprocating motion of the push plate drives the vibration component to vibrate, thereby vibrating the sand in the storage box.

[0014] Sand is blown to the supporting component through the wind component to conduct a simulation experiment on plant resistance to wind and sand environment.

[0015] The above scheme has the following beneficial effects:

[0016] 1. The present invention improves the flow efficiency of sand through the pushing of the pushing plate, reduces the blockage and accumulation of sand during the flow process, and is conducive to ensuring the smooth progress of the plant resistance to wind and sand environment simulation experiment.

[0017] 2. The present invention vibrates the sand through the vibration component, so that the sand is always in a loose state, which is conducive to the pushing of the pushing plate.

[0018] Furthermore, a first fixing column and a second fixing column are fixedly connected to the inner side wall of the storage box.

[0019] The vibration assembly includes a second connecting rod and a vibration plate. One end of the second connecting rod is hinged to the side of the push plate close to the first connecting rod. The end of the second connecting rod away from the push plate is hinged to the third connecting rod. The middle part of the third connecting rod is rotatably matched with the first fixed column.

[0020] The second fixed column is rotatably matched with the fourth connecting rod, and the end of the fourth connecting rod away from the second fixed column is hinged with a pushing rod, and the middle part of the pushing rod is hinged with the end of the third connecting rod away from the second connecting rod.

[0021] The vibration plate is located in the storage box and is slidably matched with the inner wall of the storage box, and the second fixing column is in contact with the vibration plate.

[0022] A plurality of springs are fixedly connected to one side of the vibration plate away from the second fixed column, and one end of the springs away from the vibration plate is fixedly connected to the inner wall of the storage box.

[0023] Beneficial Effect: Through the linkage of the second, third, and fourth connecting rods and the push rod, the vibrating plate generates reciprocating motion and vibration within the storage box. This vibration effectively breaks the static friction between the sand and prevents sand from clumping within the storage box, thereby ensuring smooth flow and even delivery of the sand.

[0024] The pushing rod can push the sand in the storage box to the discharge port, and push it through the pushing plate, which further improves the pushing efficiency of the pushing plate.

[0025] Furthermore, the temporary storage component includes a temporary storage box, which is fixedly connected to the bottom wall of the blowing box, the top of the temporary storage box is connected to the guide pipe, an air inlet is opened on the side wall of the temporary storage box, the air inlet is connected to the wind power component, and an air outlet is opened on the side wall of the temporary storage box away from the air inlet, and the air outlet is connected to the bearing component.

[0026] Beneficial effect: Sand is temporarily stored in the temporary storage box. When the wind component is started, the airflow generated by the wind component will blow the sand in the temporary storage box from the air outlet to the carrying component through the air inlet, thereby improving the sand blowing efficiency and improving the accuracy of the plant resistance to wind and sand environment simulation experiment.

[0027] Furthermore, the wind power component includes a blower, and the controller is used to control the opening and closing of the blower. The blower is fixedly connected to the blowing box, and the air outlet of the blower is connected to the air inlet.

[0028] Beneficial effect: Through the connection between the air delivery port and the air inlet of the blower, the air flow is directly introduced into the temporary storage box, providing sufficient power for blowing the sand.

[0029] Furthermore, the bearing assembly includes a bearing groove, the bearing groove is fixedly connected to the bottom wall of the blowing box, and the air outlet is communicated with the bearing groove.

[0030] Beneficial effects: The bearing trough is fixedly connected to the bottom wall of the blowing box. This design ensures the stability of the plants planted in the bearing trough during the sand blowing process, which facilitates the experiment.

[0031] Furthermore, a collecting box is provided on a side of the bearing tank away from the temporary storage box, and the collecting box is fixedly connected to the inner wall of the blowing box.

[0032] Beneficial effect: Collecting sand through a collection box can ensure that the sand is effectively collected after blowing through the plants, preventing the sand from being scattered and causing a mess in the experimental environment.

[0033] Furthermore, the inner bottom wall of the temporary storage box is inclined, and the side of the inner bottom wall of the temporary storage box close to the air outlet is lower than the side of the air inlet.

[0034] Beneficial effect: The inclined inner bottom wall is conducive to the flow of sand in the temporary storage box toward the air outlet side, which is conducive to the subsequent blowing of sand by the blower and improves the blowing efficiency of sand.

[0035] Furthermore, a box door is hinged on one side of the blowing box, and a handle is fixedly connected to the box door.

[0036] Beneficial effects: The design of the box door allows the staff to easily open the blowing box and place the plants in the carrying tank. After the experiment, the workers can take out the plants by opening the box door to observe the experimental results.

[0037] Furthermore, an anti-stick coating is fixedly connected to the inner wall of the guide tube.

[0038] Beneficial Effects: The anti-stick coating can effectively reduce the adhesion between sand and the pipe wall, thereby reducing the risk of sand blockage and improving the efficiency of sand transportation in the guide pipe.

[0039] Furthermore, a plurality of reinforcement blocks are fixedly connected to the bottom of the blowing box.

[0040] Beneficial effects: The reinforcement blocks can significantly enhance the structural stability and bearing capacity of the blowing box, thereby improving the accuracy of the plant resistance to wind and sand environment simulation experiment.

[0041] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The following is further described in detail through specific implementation methods:

[0047] Example 1:

[0048] As attached Figure 1-Figure 3 As shown: A wind and sand blowing structure for simulating plants' resistance to wind and sand environment, including a storage box 1 and a blowing box 6, the bottom of the storage box 1 is detachably connected to the top of the blowing box 6; a feed port 2 is provided at the top of the storage box 1, and a discharge port 18 is provided at the bottom of the storage box 1, and a guide tube 20 is fixedly connected to the discharge port 18 by screws, and the end of the guide tube 20 away from the discharge port 18 passes through the blowing box 6 and extends to the inside of the blowing box 6.

[0049] A temporary storage component for temporarily storing sand is provided in the blowing box 6 , and the temporary storage component is communicated with an end of the guide pipe 20 away from the discharge port 18 .

[0050] A pushing assembly for pushing sand is provided in the storage box 1 , and a vibrating assembly for vibrating the sand is provided on one side of the pushing assembly.

[0051] The controller is fixedly connected to the outer wall of the storage box 1 by screws.

[0052] The blowing box 6 is provided with a wind component for blowing sand and a bearing component for bearing plants.

[0053] like Figure 2 As shown, the pushing assembly includes a driving member. In this embodiment, the driving member is selected as a driving motor 10. The controller is used to control the operation of the driving motor 10. The driving motor 10 is bolted and fixedly connected to the inner wall of the storage box 1. The output shaft of the driving motor 10 is bolted and fixedly connected to the transmission rod 11. The end of the transmission rod 11 away from the driving motor 10 is hinged to the first connecting rod 12, and the end of the first connecting rod 12 away from the transmission rod 11 is hinged to the pushing plate 13.

[0054] Combine Figure 3 As shown, the storage box 1 is fixedly connected with a limit frame 19 by bolts, and the pushing plate 13 is located in the limit frame 19 and slidably cooperates with the inner wall of the limit frame 19.

[0055] A first fixing column 9 and a second fixing column 8 are fixedly connected to the inner wall of the storage box 1 by bolts.

[0056] The vibration assembly includes a second connecting rod 14 and a vibration plate 7. One end of the second connecting rod 14 is hinged to the side of the push plate 13 close to the first connecting rod 12. The end of the second connecting rod 14 away from the push plate 13 is hinged to a third connecting rod 15. The middle part of the third connecting rod 15 is rotatably engaged with the first fixed column 9.

[0057] The second fixing column 8 is rotatably engaged with the fourth connecting rod 16 , and the end of the fourth connecting rod 16 away from the second fixing column 8 is hinged to a push rod 17 , and the middle part of the push rod 17 is hinged to the end of the third connecting rod 15 away from the second connecting rod 14 .

[0058] The vibration plate 7 is located in the storage box 1 and is in sliding engagement with the inner wall of the storage box 1 , and the second fixing column 8 is in contact with the vibration plate 7 .

[0059] A plurality of springs 25 are fixedly connected to one side of the vibration plate 7 away from the second fixing column 8 by screws, and one end of the springs 25 away from the vibration plate 7 is fixedly connected to the inner wall of the storage box 1 by screws.

[0060] The temporary storage component includes a temporary storage box 22, which is bolted to the inner bottom wall of the blowing box 6. The top of the temporary storage box 22 is connected to the guide pipe 20. An air inlet is opened on the side wall of the temporary storage box 22, and the air inlet is connected to the wind power component. An air outlet is opened on the side wall of the temporary storage box 22 away from the air inlet, and the air outlet is connected to the bearing component.

[0061] The wind power component includes a blower 21. The controller is used to control the opening and closing of the blower 21. The blower 21 is fixedly connected to the blowing box 6 by bolts. The air delivery port of the blower 21 is connected to the air inlet.

[0062] The bearing assembly includes a bearing groove 23 , which is fixedly connected to the inner bottom wall of the blowing box 6 by bolts, and the air outlet is communicated with the bearing groove 23 .

[0063] A collecting box 24 is provided on one side of the bearing tank 23 away from the temporary storage box 22 , and the collecting box 24 is fixedly connected to the inner wall of the blowing box 6 by bolts.

[0064] A box door 3 is hinged on one side of the blowing box 6, and a handle 4 is fixedly connected to the box door 3 by screws.

[0065] The specific implementation process is as follows: first, the staff can open the box door 3 through the handle 4, then plant the plants that need to undergo the wind and sand environment simulation experiment in the bearing groove 23, and then close the box door 3.

[0066] The staff can then add sand into the storage box 1 through the feed port 2, and then control the drive motor 10 to start through the controller.

[0067] by Figure 2 For example, when the drive motor 10 is started, the output shaft of the drive motor 10 will drive the transmission rod 11 to rotate. When the transmission rod 11 rotates, it will drive the first connecting rod 12 to reciprocate. The reciprocating motion of the first connecting rod 12 will push the push plate 13 to slide along the inner wall of the limit frame 19. As the push plate 13 slides, the sand in the storage box 1 will be pushed by the push plate 13 through the discharge port 18 into the guide tube 20.

[0068] The pushing of the sand by the pushing plate 13 can enable the sand to be pushed into the guide tube 20 continuously and stably, thereby reducing the accumulation and storage of sand in the storage box 1 and improving the sand transportation efficiency.

[0069] Combine Figure 3 As shown, when the pushing plate 13 slides back and forth in the limit frame 19, the pushing plate 13 will drive the second connecting rod 14 to swing. When the second connecting rod 14 swings, it will drive the third connecting rod 15 to swing. The swing of the third connecting rod 15 will drive the fourth connecting rod 16 to swing, and then drive the pushing rod 17 to reciprocate, continuously pushing the sand in the storage box 1 to gather in the direction of the discharge port 18, thereby improving the utilization rate of the sand in the storage box 1 and reducing the waste of sand.

[0070] As the fourth connecting rod 16 swings rightward, it pushes the vibration plate 7 to slide rightward within the storage box 1. As the vibration plate 7 moves rightward, the volume of the storage box 1 increases, and the vibration plate 7 presses the spring 25, compressing the spring 25. At this time, the sand is dispersed due to the increased volume of the storage box 1, reducing the clumping of sand.

[0071] When the fourth connecting rod 16 swings to the left, the vibration plate 7 moves to the left under the action of the elastic force of the spring 25, squeezing the sand, thereby further promoting the sand to slide from the discharge port 18 into the guide tube 20.

[0072] The blower 21 can be started before the staff adds sand from the feed port 2. At this time, as the sand continues to fall from the guide tube 20 into the temporary storage box 22, the gas blown out by the blower 21 will continuously blow the sand in the temporary storage box 22 through the air outlet to the plants in the supporting tank 23, thereby completing the plant resistance to wind and sand environment simulation experiment.

[0073] The sand blown through the carrying trough 23 is collected by the collecting box 24 , thereby reducing the scattering of sand in the blowing box 6 .

[0074] When the plant resistance to wind and sand environment simulation experiment is completed, the staff can turn off the drive motor 10 and the blower 21, then open the box door 3, take out the plant and observe the experimental results.

[0075] Example 2:

[0076] like Figure 3 As shown, the difference from the above embodiment is that the inner bottom wall of the temporary storage box 22 is inclined, and the side of the inner bottom wall of the temporary storage box 22 close to the air outlet is lower than the side of the air inlet.

[0077] The specific implementation process is as follows: in the process of sand falling into the temporary storage box 22 through the guide tube 20, since the inner bottom wall of the temporary storage box 22 is lower than the side close to the air inlet near the air outlet, the sand entering the temporary storage box 22 will continue to slide toward the air outlet under the action of gravity. At this time, the airflow blown out by the blower 21 will fully blow the sand, which is more conducive to the blower 21 blowing the sand out of the air outlet, completing the plant resistance to wind and sand environment simulation experiment.

[0078] Example 3:

[0079] The difference from the above embodiment is that an anti-stick coating is bonded to the inner wall of the guide tube 20. In this embodiment, the anti-stick coating is preferably a polyurethane anti-corrosion coating.

[0080] The specific implementation process is as follows: As sand flows through the guide tube 20 into the temporary storage box 22, it may adhere to the inner wall of the pipe due to friction and static electricity, which not only affects the sand's flow efficiency but also may cause pipe blockage. However, the polyurethane anti-corrosion coating can significantly reduce the adhesion between the sand and the inner wall of the pipe, allowing the sand to pass smoothly through the guide tube 20 and enter the blowing box 6.

[0081] Example 4:

[0082] like Figure 1 As shown, the difference from the above embodiment is that a plurality of reinforcement blocks 5 are fixedly connected with bolts at the bottom of the blowing box 6 .

[0083] The specific implementation process is as follows: the blowing box 6 is supported by the reinforcement block 5 to improve the stability of the blowing box 6 during the entire experimental process and improve the anti-overturning ability, thereby improving the accuracy of the plant resistance to wind and sand environment simulation experiment.

[0084] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
