Description

Technical Field

[0001] The invention relates to the technical field of sunshade devices, and in particular to a wind-resistant sunshade device for crop cultivation. Background Art

[0002] Some crops need to be shaded at certain stages during their growth to reduce direct sunlight or lower the temperature, such as pinellia, edible fungi, and some fruits and vegetables. Among them, Morchella cultivation, especially the mushroom production stage, needs to be shaded from light. At present, the most widely used is a flat shed built in the field. Several poles are inserted around and inside the crop planting area, and a wire mesh is set above the pole. The sunshade net is covered on the wire mesh, and the sunshade net is hung along the four sides and fixed with sandbags. At the top of each pole, the sunshade net and the pole are fixed with wire. Although this sunshade can achieve a certain sunshade effect and has a low cost, the construction process is cumbersome, and the installation and disassembly are time-consuming and laborious; the wind resistance is poor, and the sunshade net is prone to collapse in rain, snow or strong winds, which will cause large-scale death of Morchella, resulting in reduced production or even total crop failure. Once there are continuous rainy days, if the sunshade is not opened in time for ventilation, the field will be too wet, resulting in dead mushrooms. Summary of the invention

[0023] The above-mentioned wind-resistant sunshade device for crop cultivation is used. When in use, all T-shaped sliders 101 and support columns 2 are first installed on the base plate 1, and the cross bar 3 is inserted between the two support columns 2 of each group. The position of the T-shaped slider 101 located at the end is locked using a screw, so that the position of a group of support columns 2 located at the end is fixed. At the same time, the two driving motors 7 that control the rotation of the two first screw rods 6 are turned on, and the driving motor 7 drives 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, the support columns 2 behind it are driven to move one by one, and finally all the support columns 2 are moved to the target position, thereby completing the construction of the general frame structure. Then the sunshade net 12 is covered on the entire frame surface, and it is hung and fixed around. The present invention is easy to disassemble and assemble, convenient for transportation, and can effectively improve work efficiency and reduce labor intensity. When the sunshade net needs to be removed on continuous rainy days, the driving motor 7 is controlled to reverse, so that the support column 2 drives the sunshade net 12 to return to one end together, accelerates the evaporation of water, and prevents too much water from causing a reduction in production or even a total crop failure. The support columns 2 in the present invention are detachably mounted on the base plate 1 through a T-shaped slider 101 and a T-shaped slide groove. The T-shaped slider 101 is fixed to the base plate 1 by screws. The base plate 1 is provided with a strip groove for installing screws. The installation structure is simple, stable, and has strong wind resistance, which can effectively prevent the sunshade net 12 from collapsing and causing large-scale crop death.

[0024] Specifically, a fixed clamping plate 10 is fixedly installed on the bottom plate 1; a movable clamping plate 11 is also provided on the bottom plate 1; one end of the sunshade 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 sunshade net 12 hang down, and the left and right sides are clamped between the movable clamping plates 11 and the fixed clamping plates 10 on both sides, and the clamping stability is good.

The top of the sunshade net 12 is fixed by the fixed clamping blocks 8 and the movable clamping strip 9, thereby improving the bearing capacity and wind resistance of the top of the sunshade net 12.

[0026] In another embodiment, the movable clamping strip 9 can be replaced with a plurality of movable clamping blocks. During installation, the movable clamping block is installed on the fixed clamping block 8 according to the needs and the difficulty of operation, so that the sunshade net 12 is clamped between the fixed clamping block 8 and the movable clamping block. When the sunshade net 12 needs to be opened for ventilation, it is only necessary to remove the movable clamping strip 9, release the clamping of the two sides and the front end of the sunshade net 12, and control the driving motor 7 to reverse, so as to drive the support column 2 together with the cross bar 3, the fixed clamping block 8 and the movable clamping block to drive the sunshade net 12 back to one end.

[0027] Specifically, in order to improve the stability of clamping, the contact surface between the fixed clamping plate 10 and the movable clamping plate 11, as well as the contact surface between the fixed clamping block 8 and the movable clamping bar 9 are provided with clamping teeth.

[0028] Specifically, in order to further improve the stability and bearing capacity of the device, a plurality of support rods 4 are further included; the bottom of the support rod 4 is inserted into the soil, and the top is abutted against the bottom of the cross bar 3 .

[0029] Specifically, the support rod 4 is composed of a plug rod 402 with a spike portion and a rod sleeve 401 threadedly connected to the plug rod 402. When in use, the plug rod 402 is first inserted into the soil at an appropriate position, and then the plug rod 402 is held to keep it from rotating as much as possible, and the rod sleeve 401 is rotated to make the length of the support rod 4 longer, until the top of the rod sleeve 401 abuts against the bottom of the cross bar 3.

The lifting motors 205 on both sides are turned on synchronously, and all the screw sleeves 202 on both sides can be driven to rotate synchronously through the chain transmission assembly, and the second screw rod 203 cannot rotate under the restriction of the cross bar 3, so that the screw sleeve 202 rotates to drive the second screw rod 203 to move up and down, so as to adjust the sunshade height.

[0034] Specifically, in order to adapt to plots of different sizes and to facilitate installation of the crossbar, the crossbar 3 is formed by connecting an inner rod 301 and an outer rod 302. In addition, when not in use, the inner rod 301 and the outer rod 302 are disassembled for easy storage and transportation. In this embodiment, the inner rod 301 and the outer rod 302 are connected by a multi-rod threaded connection.

[0035] Specifically, in order to facilitate fixing the position of the bottom plate 1 , a plurality of spikes are connected to the bottom of the bottom plate 1 .

[0036] Working principle of the present invention: When in use, first level and tamp the soil around the plot. Move the base plate 1 to both sides of the plot and place it so that the two base plates 1 are parallel. Install all T-shaped sliders 101 on the base plate 1, insert the crossbar 3 between the jacks 207 of the two support columns 2 of each group, and use screws to lock the position of the T-shaped slider 101 at one end, so that the position of a group of support columns 2 at one end is fixed. At the same time, turn on the two driving motors 7 that control the rotation of the two first screw rods 6, and the driving motor 7 drives 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, the support columns 2 behind it are driven to move one by one, and finally all the support columns 2 are moved to the target position, thereby completing the construction of the general frame structure. Then the sunshade net 12 is covered on the entire frame surface and hung down all around. The left and right ends of the sunshade net 12 are clamped between the movable clamping plate 11 and the fixed clamping plate 10 on both sides, and the clamping stability is good. The front and rear sides can be pressed down with sandbags, or the bottom plate 1 can be respectively provided on the front and rear sides, and a movable clamping plate 11 and a fixed clamping plate 10 are provided on the bottom plate 1, and the front and rear ends of the sunshade net 12 are clamped between the movable clamping plate 11 and the fixed clamping plate 10. Then the movable clamping bar 9 is placed in the corresponding position, and the two ends of the movable clamping bar 9 are installed on the fixed clamping block 8 with screws, so that the sunshade net 12 is tightly clamped between the fixed clamping block 8 and the movable clamping bar 9.

[0037] The present invention is easy to disassemble and assemble, convenient to transport, can effectively improve work efficiency and reduce labor intensity. When the sunshade net 12 needs to be removed in continuous rainy days, it is only necessary to remove the movable clamping strip 9, release the clamping of the two sides and the front end of the sunshade net 12, and pull the sunshade net 12 to the rear end for clamping. It can accelerate the evaporation of water and prevent the reduction of production or even the failure of harvest due to too much water.

[0038] The support columns 2 in the present invention are detachably mounted on the base plate 1 through a T-shaped slider 101 and a T-shaped slide groove. The T-shaped slider 101 is fixed to the base plate 1 by screws. The base plate 1 is provided with a strip groove for installing screws. The installation structure is simple, stable, and has strong wind resistance, which can effectively prevent the sunshade net 12 from collapsing and causing large-scale crop death.
