Description

Technical Field

[0001] The utility model relates to the technical field of ecological planting, in particular to a planting device suitable for saline-alkali land. Background Art

[0002] Saline-alkali land refers to land with excessive accumulation of soluble salts on the soil surface. The essence of its formation is the horizontal and vertical redistribution of various soluble salts on the ground, causing salt to gradually accumulate on the soil surface in the salt-collecting area. The saline-alkali hazard makes it difficult to utilize large areas of soil resources and reduces the comprehensive agricultural production capacity.

[0003] When planting on saline-alkali land, rainwater is easily trapped on the planting substrate and is difficult to drain away, resulting in excessive moisture in the planting substrate and making the plant roots prone to rot. For this reason, a Chinese utility model patent with patent number CN202221090414.4 (authorization announcement number CN217336597U) discloses an "ecological planting system for saline-alkali tidal flats". A V-shaped groove is opened on the top of the saline-alkali land, and rainwater flows along the V-shaped groove to a rainwater collection chamber located in the saline-alkali land, thereby draining rainwater from the planting substrate and avoiding excessive moisture on the planting substrate. However, the planting system has the following problems: First, a rainwater collection chamber for collecting rainwater is opened underground in the saline-alkali land, which requires professional personnel to design and excavate. This process is labor-intensive and increases the time and manpower required before planting on the saline-alkali land; second, the rainwater collection chamber is a closed environment, and rainwater in the rainwater collection chamber for a long time is prone to breed bacteria and microorganisms, and the rainwater collection chamber opened underground is not convenient for people to enter for cleaning and is difficult to maintain. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a planting device suitable for saline-alkali land with less initial investment and less likelihood of bacterial growth, in response to the above-mentioned existing technical status.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: the planting device suitable for saline-alkali land is characterized in that it includes a main body and a deflector, the main body includes a roof and a connecting frame that maintains the roof and the saline-alkali land to be treated at a preset height, and a downspout is provided on the roof, and the deflector is at least partially connected to the connecting frame and is located below the downspout, for guiding rainwater to the root area of ​​the plants.

[0006] To direct rainwater to the root zone of the plant, the deflector preferably includes an inner side facing the root zone of the plant and an outer side connected to the connecting frame. The inner side is lower than the outer side, and the outer side of the deflector gradually and smoothly slopes downward to the inner side. The outer side is located below the downspout. After falling from the downspout, rainwater enters the deflector from the outer side, flows downward along the deflector, and flows out from the inner side to the root zone.

[0007] In order to filter solid impurities in rainwater, preferably, the inner side of the deflector is provided with a filter element for filtering rainwater.

[0008] To better direct rainwater to the root zone of the plants, preferably, at least two downspouts are spaced apart along the length of the roof, and a deflector corresponds to every other or more downspouts. The width of the outer edge of the deflector is greater than the width of the inner edge, and the portion of the outer edge of the deflector extending to the inner edge is at least partially concave. Having a deflector corresponding to every other or more downspouts can reduce the number of deflectors provided. The width of the outer edge of the deflector is greater than the width of the inner edge, which allows the deflector to better receive rainwater falling from the downspouts. The concave surface of the deflector, at least partially, allows rainwater entering the deflector to flow more fully along the deflector to the root zone of the plants.

[0009] In order to adjust the amount of rainwater directed from the deflector to the root area, the deflector is preferably made of a flexible material, and the connecting frame is provided with a conversion mechanism that enables the outer edge of the deflector to switch between an extended position and a retracted position. The aforementioned correspondence between one or more water outlets and the width of the outer edge of the deflector being greater than the width of the inner edge enable the deflector to be expanded or retracted to a greater extent, increasing the range of rainwater volume that can be adjusted when the deflector switches between the extended and retracted positions. When the outer edge of the deflector is in the extended position, the amount of rainwater entering the deflector from the water outlet is increased; when the outer edge is in the retracted position, the amount of rainwater entering the deflector from the water outlet is reduced.

[0010] In order to enable the outer side of the deflector to switch between the deployed position and the retracted position, the conversion mechanism preferably includes a drive source and a transmission mechanism that converts the driving force of the drive source into a transmission mechanism that switches the outer side of the deflector between the deployed position and the retracted position along the length of the roof. The drive source can be an electric or pneumatic device with a driving capability.

[0011] In order to transmit the driving force of the driving source to the deflector so that the outer side of the deflector can be switched between the unfolded position and the folded position along the length direction of the roof, preferably, the transmission mechanism includes

[0012] A screw rod is provided on the connecting frame along the length direction of the roof, and is provided with a threaded portion corresponding to each deflector, wherein the threaded portion includes a first threaded segment and a second threaded segment arranged in opposite directions;

[0013] Two connecting pieces are provided for each threaded portion, respectively provided at the first threaded segment and the second threaded segment, and respectively connected to the two ends of the outer side of the deflector, and the connecting piece has a threaded hole matching the threaded portion;

[0014] When the screw rod rotates forward, the two connecting parts approach each other, and the outer side of the deflector is converted from the expanded position to the retracted position; when the screw rod rotates backward, the two connecting parts move away from each other, and the outer side of the deflector is converted from the retracted position to the open position.

[0015] In order to prevent the connecting member from rotating with the screw, preferably, the connecting member is further provided with a limiter for preventing the connecting member from rotating relative to the screw. The setting of the limiter can limit the rotation of the connecting member when the screw rotates, thereby preventing the transmission mechanism from failing due to the connecting member rotating with the screw.

[0016] The limiting member can be any structure that can limit the rotation of the connecting member. From the perspective of structural simplicity, preferably, the limiting member is a limiting rod, the connecting member is provided with a through hole, and the limiting rod passes through the through hole and is connected to the connecting frame.

[0017] In order to be able to adjust the amount of rainwater guided by the deflector according to the salinity and pH value of the saline-alkali land, preferably, it also includes a sensor and a controller for detecting the salinity and pH value of the saline-alkali land to be treated. The controller is connected to the sensor and the conversion mechanism, and is configured to: control the outer edge of the deflector to switch between the expanded position and the retracted position according to the salinity and pH value detected by the sensor.

[0018] Compared with the existing technology, the advantages of the present invention are that the planting device suitable for saline-alkali land only includes a roof, a connecting frame that maintains a preset height between the roof and the saline-alkali land to be treated, and a deflector for guiding rainwater from the downspout opened on the roof to the root area of ​​the plant. Only these simple components form an open space. Not only is the structure simple, but the entire process of rainwater flowing to the root area of ​​the plant is a dynamic process, which avoids the occurrence of bacteria breeding due to rainwater storage.

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-5 Shown is a preferred embodiment of the present utility model.

[0026] The planting device for saline-alkali land of this embodiment includes a main body 1 and a deflector 2. The main body 1 includes a roof 11 and a connecting frame 12 that maintains a preset height between the roof 11 and the saline-alkali land A to be treated. The roof 11 is U-shaped, with its opening facing the saline-alkali land A to be treated. Multiple downspouts 13 are spaced along the length of the roof 11 on both sides of the U-shape. Each two downspouts 13 correspond to a deflector 2. Rainwater falling on the roof 11 can flow along the U-shaped roof 11 to the downspouts 13 on both sides, thereby increasing the amount of rainwater that can fall from the downspouts 13.

[0027] The deflector 2 is made of a flexible material and includes an inner side edge 21 facing the root area of ​​the plant B and an outer side edge 22 connected to the connecting frame 12 and having a width greater than the inner side edge 21. The height of the inner side edge 21 is lower than the height of the outer side edge 22. The outer side edge 22 is located below the downspout 13 and gradually and smoothly extends downward to the inner side edge 21. The portion of the outer side edge 22 of the deflector 2 extending to the inner side edge 21 is at least partially concave, and the inner side edge 21 is provided with a filter element 23 for filtering rainwater. In this way, after rainwater falls from the downspout 13, it enters the deflector 2 from the outer side edge 22, and flows to the root area of ​​the plant B after being filtered along the deflector 2 which is at least partially concave, thereby supplying water to the root area.

[0028] The outer edge 22 of the deflector 2 is connected to the connecting frame 12 via a conversion mechanism 3 and can be converted between an extended position and a retracted position along the length of the roof 11. Specifically, the conversion mechanism 3 includes a drive source 31 and a transmission mechanism 32 that converts the driving force of the drive source 31 to convert the outer edge 22 of the deflector 2 between the extended position and the retracted position along the length of the roof 11. The transmission mechanism 32 includes a screw rod 321 and a connector 323. The screw rod 321 is disposed on the connecting frame 12 along the length of the roof 11. A threaded portion 322 is provided for each deflector 2. The threaded portion 322 includes a first threaded segment 322a and a second threaded segment 322b arranged in opposite directions. Two connectors 323 are provided for each threaded portion 322, one at each of the first threaded segment 322a and the other at each of the second threaded segments 322b. The connectors 323 are connected to both ends of the outer edge 22 of the deflector 2, and each connector 323 has a threaded hole 3231 that mates with the threaded portion 322.

[0029] In addition, the deflector 2 can also adjust the amount of rainwater directed from the deflector 2 to the root area according to the salinity and pH values ​​of the saline-alkali land. Specifically, it includes a sensor for detecting the salinity and pH values ​​of the saline-alkali land A to be treated and a controller. The controller is connected to the sensor and the conversion mechanism 3 and is configured to control the outer edge 22 of the deflector 2 to switch between the expanded position and the retracted position according to the salinity and pH values ​​detected by the sensor. The specific adjustment method of the conversion mechanism 3 is as follows: when it is necessary to reduce the amount of rainwater directed to the root area, the screw rod 321 rotates forward, the two connecting parts 323 approach each other, and the outer edge 22 of the deflector 2 switches from the expanded position to the retracted position, as shown in FIG. Figure 4 As shown, the amount of rainwater that can enter the deflector 2 from the downspout 13 is reduced, thereby reducing the amount of rainwater directed to the root area; when the amount of rainwater directed to the root area needs to be increased, the screw rod 321 rotates in the opposite direction, the two connecting members 323 move away from each other, and the outer side 22 of the deflector 2 is converted from the retracted position to the open position, as shown in FIG. Figure 1 As shown, the amount of rainwater that can enter the deflector 2 from the downspout 13 is increased, thereby increasing the amount of rainwater guided to the root area.

[0030] In order to prevent the connecting member 323 from rotating with the screw rod 321 when the screw rod 321 rotates, a limiting member 4 is provided on the connecting member 323 to prevent the connecting member 323 from rotating relative to the screw rod 321. In this embodiment, the limiting member 4 is a limiting rod, and a through hole 3232 is provided on the connecting member 323. The limiting rod passes through the through hole 3232 and is connected to the connecting frame 12.

[0031] In addition, since the rainwater falling from the downspout 13 can fall directly onto the saline-alkali land A to be treated when the deflector 2 is in the folded state, in order to avoid this part of the rainwater being difficult to drain away from the saline-alkali land A to be treated, which may cause the roots of the plant B to be rotted due to excessive moisture, the saline-alkali land A to be treated can be designed to have the saline-alkali land on both sides of the plant B as a downward sloping surface, and a rainproof cloth is laid on the slope, so that the rainwater falling directly from the downspout 13 falls onto the rainproof cloth and flows away along the slope away from the root area of ​​the plant B.
