Description

Technical Field

[0001] This invention relates to the field of shading device technology, and in particular to a wind-resistant shading device for crop cultivation. Background Art

[0002] Some crops require shading at certain stages of their growth to reduce direct sunlight or lower temperatures, such as Pinellia ternata, edible fungi, and some melons and vegetables. Morel mushroom cultivation, especially during the fruiting stage, requires shade. Currently, a widely used method is to construct a flat shed in the field. Several poles are inserted around the crop planting area and inside, with wire mesh placed above the poles. The shade netting is then placed over the wire mesh, hanging down along the perimeter and secured with sandbags. The top of each pole is secured to the shade netting with wire. While this type of shade shed provides some shading and is relatively inexpensive, the construction process is cumbersome, and installation and dismantling are time-consuming and labor-intensive. It also has poor wind resistance; in rainy, snowy, or windy weather, the shade netting is prone to collapse, leading to widespread death of morel mushrooms, reduced yield, or even total crop failure. Furthermore, if the shade shed is not opened for ventilation during prolonged periods of rain, excessive soil moisture can cause mushroom death. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a wind-resistant shading device for crop cultivation that is easy to assemble and disassemble, can effectively improve work efficiency and reduce labor intensity; the installation structure is stable and has strong wind resistance.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is a wind-resistant shading device for crop cultivation, comprising a base plate; T-shaped grooves are provided on two opposite base plates; a plurality of T-shaped sliders are slidably installed in the T-shaped grooves; a support column is fixedly connected to the top of the T-shaped slider; an insertion hole is provided on the upper side wall of the support column; a crossbar is installed between the insertion holes of two opposite support columns in the same group; a first lead screw is rotatably installed between the two ends of the base plate; a nut block that is threadedly connected to the first lead screw is fixedly connected to the side wall of one group of support columns at one end, and a connecting block that is slidably connected to the first lead screw is fixedly connected to the side wall of the remaining groups of support columns; ropes are connected between the nut block and the connecting block, and between adjacent connecting blocks; a shading net surrounds the crossbar and the support column.

[0005] Furthermore, a fixed clamping plate is fixedly installed on the base plate; a movable clamping plate is also provided on the base plate; one end of the shade net is clamped between the movable clamping plate and the fixed clamping plate; the movable clamping plate and the fixed clamping plate are connected by bolts or screws.

[0006] Furthermore, each of the crossbars has several fixed clamping blocks fixedly attached to its top at intervals; each set of fixed clamping blocks at corresponding positions has a movable clamping strip detachably installed on its top; the shade net is clamped between the fixed clamping blocks and the movable clamping strips; both ends of each movable clamping strip are screwed to the fixed clamping block below it.

[0007] Furthermore, the contact surfaces of the fixed clamping plate and the movable clamping plate, as well as the contact surfaces of the fixed clamping block and the movable clamping bar, are all provided with clamping teeth.

[0008] Furthermore, it also includes several support rods; the bottom of the support rods is inserted into the soil, and the top of the support rods abuts against the bottom of the crossbar.

[0009] Furthermore, the support rod consists of a spiked insert and a sleeve threadedly connected to the insert.

[0010] Furthermore, the side of the shade net is provided with an openable doorway.

[0011] Furthermore, a roller is installed on the top side wall of the support column; the shade net passes around the roller.

[0012] Furthermore, the support column is a retractable structure.

[0013] Furthermore, the support column includes a sleeve fixed to the top of the T-shaped slider; a threaded sleeve is rotatably installed inside the sleeve; a second lead screw is threadedly connected inside the threaded sleeve; the insertion hole is opened on the upper side wall of the second lead screw; two sprockets are installed on the portion of the threaded sleeve that extends beyond the sleeve; the sprockets of two adjacent support columns on the same side are connected by a transmission chain; the sprocket of the support column at one end is connected to a sprocket installed on the lifting motor by a transmission chain.

[0014] Furthermore, the crossbar is formed by connecting an inner bar and an outer bar.

[0015] Furthermore, the bottom of the base plate is connected to several spikes.

[0016] Beneficial effects of this invention:

[0017] First, install all the T-shaped sliders and support columns. Insert the crossbar between the two support columns in each group to lock the position of the T-shaped sliders at the ends, thus fixing the position of the support columns at the ends. Turn on the drive motor that controls the rotation of the first lead screw. The drive motor drives the nut block on the side wall of the support column at the other end to move forward. Under the action of the rope, it drives the support columns behind it to move one by one until all the support columns are moved to the target position, thus completing the construction of the basic frame structure. Then, place the sunshade net over the entire frame surface, hang it down around the edges, and fix it.

[0018] This invention is easy to assemble and disassemble, convenient to transport, and can effectively improve work efficiency and reduce labor intensity. When it is necessary to remove the shade net during continuous rainy days, simply remove the movable clamping strip, release the clamps on both sides and the front end of the shade net, and control the drive motor to reverse. This will allow the support column to pull the shade net back to one end, accelerating moisture evaporation and preventing excessive moisture from causing reduced yield or even crop failure.

[0019] The support columns in this invention are detachably installed on the base plate via T-shaped sliders and T-shaped grooves, and the T-shaped sliders are fixed to the base plate with screws. The installation structure is simple, stable, and has strong wind resistance, which can effectively prevent the shade net from collapsing and causing large-scale crop death.

Detailed Implementation

[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Example 1

[0029] A wind-resistant shading device for crop cultivation, such as Figure 1-5 As shown, the system includes a base plate 1; two opposing base plates 1 are provided with T-shaped grooves; several T-shaped sliders 101 are slidably installed in the T-shaped grooves; a support column 2 is fixedly connected to the top of the T-shaped slider 101; an insertion hole 207 is provided on the upper side wall of the support column 2; a crossbar 3 is installed between the insertion holes 207 of two opposing support columns 2 in the same group; a first lead screw 6 is rotatably installed between the two ends of the base plate 1; a nut block 5 that is threadedly connected to the first lead screw 6 is fixedly connected to the side wall of one group of support columns 2 at one end; a connecting block 14 that is slidably connected to the first lead screw 6 is fixedly connected to the side wall of the remaining groups of support columns 2; ropes 15 are connected between the nut block 5 and the connecting block 14, and between adjacent connecting blocks 14; a shade net 12 surrounds the crossbar 3 and the support column 2.

[0030] The aforementioned wind-resistant shading device for crop cultivation is used by first installing all T-shaped sliders 101 and support columns 2 onto the base plate 1. The crossbar 3 is then inserted between the two support columns 2 in each group. Screws are used to lock the position of the T-shaped sliders 101 at the ends, thus fixing the position of the support columns 2 at the ends. Simultaneously, the two drive motors 7, which control the rotation of the two first lead screws 6, are activated. The drive motors 7 drive the nut blocks 5 on the side walls of the support columns 2 at the other end to move forward. Under the action of the rope 15, the support columns 2 behind them move one by one until all support columns 2 are moved to the target position, thus completing the construction of the basic frame structure. Then, the shading net 12 is placed over the entire frame surface, hanging down on all sides and secured. This invention is easy to assemble and disassemble, convenient for transportation, and can effectively improve work efficiency and reduce labor intensity. When encountering continuous rainy days and needing to remove the shading net, the drive motors 7 are reversed, causing the support columns 2 to pull the shading net 12 back to one end, accelerating water evaporation and preventing excessive moisture from causing yield reduction or even crop failure. In this invention, the support columns 2 are detachably installed on the base plate 1 via T-shaped sliders 101 and T-shaped grooves. The T-shaped sliders 101 are fixed to the base plate 1 by screws. The base plate 1 has a strip groove for installing screws. The installation structure is simple, stable, and has strong wind resistance, which can effectively prevent the shade net 12 from collapsing and causing large-scale crop death.

[0031] Specifically, a fixed clamping plate 10 is fixedly installed on the base plate 1; a movable clamping plate 11 is also provided on the base plate 1; one end of the shade net 12 is clamped between the movable clamping plate 11 and the fixed clamping plate 10; the movable clamping plate 11 and the fixed clamping plate 10 are connected by bolts or screws. The four sides of the shade net 12 hang down, and both its left and right sides are clamped between the movable clamping plates 11 and the fixed clamping plates 10 on both sides, resulting in good clamping stability. Sandbags can be used to weigh down the front and back sides, or base plates 1 can be set on the front and back sides respectively, and movable clamping plates 11 and fixed clamping plates 10 can be set on the base plates 1, clamping the front and back ends of the shade net 12 between the movable clamping plates 11 and the fixed clamping plates 10.

[0032] Specifically, to further secure the shade net 12, several fixing clamping blocks 8 are fixedly attached to the top of each crossbar 3 at intervals; each set of fixing clamping blocks 8 at corresponding positions has a movable clamping strip 9 detachably installed on its top; the shade net 12 is clamped between the fixing clamping blocks 8 and the movable clamping strips 9; both ends of each movable clamping strip 9 are screwed to the fixing clamping block 8 below it. By fixing the top of the shade net 12 with the fixing clamping blocks 8 and the movable clamping strips 9, the load-bearing capacity and wind resistance of the top of the shade net 12 can be improved.

[0033] In another embodiment, the movable clamping strip 9 can be replaced with several movable clamping blocks. During installation, the movable clamping blocks are installed on the fixed clamping block 8 according to needs and operational difficulty, thereby clamping the shade net 12 between the fixed clamping block 8 and the movable clamping block. When it is necessary to open the shade net 12 for ventilation, simply remove the movable clamping strip 9, release the clamps on both sides and the front end of the shade net 12, and control the drive motor 7 to reverse, which will drive the support column 2 together with the crossbar 3, the fixed clamping block 8 and the movable clamping block to move the shade net 12 back to one end.

[0034] Specifically, in order to improve the stability of clamping, clamping teeth are provided on the contact surfaces of the fixed clamping plate 10 and the movable clamping plate 11, as well as on the contact surfaces of the fixed clamping block 8 and the movable clamping bar 9.

[0035] Specifically, in order to further improve the stability and load-bearing capacity of the device, several support rods 4 are also included; the bottom of the support rods 4 is inserted into the soil, and the top abuts against the bottom of the crossbar 3.

[0036] Specifically, the support rod 4 consists of an insert rod 402 with spikes and a sleeve 401 threadedly connected to the insert rod 402. In use, first insert the insert rod 402 into the soil at a suitable location, then hold the insert rod 402 to keep it as stationary as possible, and rotate the sleeve 401 to lengthen the support rod 4 until the top of the sleeve 401 abuts against the bottom of the crossbar 3.

[0037] Specifically, an openable doorway is provided on the side of the shade net 12 for easy access.

[0038] Specifically, a roller 13 is installed on the top side wall of the support column 2; the shade net 12 passes around the roller 13. The roller 13 can support the shade net 12 and make the shade net 12 laid more evenly.

[0039] Specifically, in order to facilitate adjustment of the shading height and ease of operation, the support column 2 is a telescopic structure.

[0040] Specifically, the support column 2 includes a sleeve 201 fixed to the top of the T-shaped slider 101; a threaded sleeve 202 is rotatably installed inside the sleeve 201; a second lead screw 203 is threadedly connected to the threaded sleeve 202; an insertion hole 207 is opened on the upper side wall of the second lead screw 203; two sprockets 204 are installed on the part of the threaded sleeve 202 that extends beyond the sleeve 201; the sprockets 204 of two adjacent support columns 2 on the same side are connected by a transmission chain 206; the sprocket 204 of the support column 2 at one end is connected to the sprocket 204 installed on the lifting motor 205 through the transmission chain 206. When the lifting motors 205 on both sides are turned on simultaneously, all the threaded sleeves 202 on both sides can be driven to rotate synchronously through the chain transmission assembly. The second lead screw 203 cannot rotate under the restriction of the crossbar 3, so that the rotation of the threaded sleeve 202 drives the second lead screw 203 to move up and down, thereby realizing the adjustment of the sunshade height.

[0041] Specifically, to accommodate plots of different sizes and for ease of installation, the crossbar 3 is composed of an inner rod 301 and an outer rod 302. Furthermore, when not in use, the inner rod 301 and outer rod 302 can be disassembled for convenient storage and transportation. In this embodiment, the inner rod 301 and outer rod 302 are connected by a multi-rod threaded connection.

[0042] Specifically, in order to facilitate fixing the position of the base plate 1, the bottom of the base plate 1 is connected with several spikes.

[0043] Working principle of the present invention:

[0044] In use, first level and compact the soil around the plot. Move the base plate 1 to both sides of the plot and place it, keeping the two base plates 1 parallel. Install all the T-shaped sliders 101 onto the base plate 1, insert the crossbar 3 between the insertion holes 207 of the two support columns 2 in each group, and use screws to lock the position of the T-shaped slider 101 at one end, thereby fixing the position of the support column 2 at one end. At the same time, turn on the two drive motors 7 that control the rotation of the two first lead screws 6. The drive motors 7 drive the nut block 5 on the side wall of the support column 2 at the other end to move forward. Under the action of the rope 15, it drives the support column 2 behind it to move one by one, until all the support columns 2 are moved to the target position, thus completing the construction of the basic frame structure. Then cover the entire frame surface with the shade net 12, hanging down on all sides. Clamp the left and right ends of the shade net 12 between the movable clamping plates 11 and the fixed clamping plates 10 on both sides, ensuring good clamping stability. The shade net 12 can be secured with sandbags on both the front and back sides, or a base plate 1 can be installed on each side, with a movable clamping plate 11 and a fixed clamping plate 10 on the base plate 1. The front and back ends of the shade net 12 are clamped between the movable clamping plate 11 and the fixed clamping plate 10. Then, the movable clamping strip 9 is placed in the corresponding position, and the two ends of the movable clamping strip 9 are installed on the fixed clamping block 8 with screws, thereby tightly clamping the shade net 12 between the fixed clamping block 8 and the movable clamping strip 9.

[0045] This invention is easy to assemble and disassemble, convenient to transport, and can effectively improve work efficiency and reduce labor intensity. When it is necessary to remove the shade net 12 due to continuous rainy days, simply remove the movable clamping strip 9, release the clamps on both sides and the front end of the shade net 12, and pull the shade net 12 together to the rear end for clamping. This can accelerate moisture evaporation and prevent excessive moisture from causing reduced yield or even crop failure.

[0046] In this invention, the support columns 2 are detachably installed on the base plate 1 via T-shaped sliders 101 and T-shaped grooves. The T-shaped sliders 101 are fixed to the base plate 1 by screws. The base plate 1 has a strip groove for installing screws. The installation structure is simple, stable, and has strong wind resistance, which can effectively prevent the shade net 12 from collapsing and causing large-scale crop death.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
