Description

Open field movable sunshade system

technical field

The invention relates to the field of agricultural infrastructure, in particular to an open field movable sunshade system.

Background technique

In summer and autumn, the sunlight intensity in Ningxia is about 100,000-160,000/LX, which is 2 times higher than the saturation point of tomatoes; and the precipitation in Ningxia is mainly concentrated in summer and autumn, mainly in heavy rain, hail, and frost, and natural disasters occur frequently. Planting fruits and vegetables has a greater impact.

From July to August is the main period for Ningxia tomatoes to go on the market, but the output of high-quality tomato fruits accounts for a very low proportion of the total output, which restricts the sales of tomatoes and leads to the problem of slow sales. Increased farmers' income and enthusiasm for planting. The color of tomatoes is a very important indicator for judging the quality of tomatoes. Usually high-quality tomatoes are usually pure red or pink, depending on the variety. But if the light is too strong, the color of the tomatoes will turn yellow, and the taste will also deteriorate. Moreover, if the fruit or leaves of tomatoes are irradiated by strong light, the local temperature of the tomato peel or leaves will be too high, and some tissues will be burnt and necrotic. Especially after the rain, when the sun shines on the plants, the sun will cause the fruit or leaves of the tomatoes to burn and cause sunburn, which will have a certain impact on the quality and yield of tomatoes. The symptoms of sunburn are that the sun-facing parts of the fruit, especially the shoulders of the fruit, fade and turn white, and then form yellow-brown spots, and some wrinkles appear, shrink and harden after drying, and sink, and the flesh is in the form of a discolored block. When the humidity is high, the brown spots of tomato fruits are easily infected or parasitized by pathogens, and black mold or rot will grow. The symptoms of sunburn are also manifested as chlorosis after the tomato leaves are damaged, and then bleached, and finally the leaf edges are scorched.

Contents of the invention

Aiming at the problem that the fruit quality of tomatoes decreases due to strong sunlight, it is necessary to provide an open-field movable sunshade system.

The traction rope 403 is used to unfold the sunshade net 50 , and the traction rope 403 on the second side of the sliding rod 405 is used to gather the sunshade net 50 .

The traction rope 403 of the present invention is conventionally used steel cables, nylon ropes and the like. Steel cables are more wear-resistant, but they are more expensive and prone to rust, especially when there is a lot of rain. Nylon rope is less expensive and more flexible, but compared to steel rope, nylon rope is not wear-resistant. These are just two examples cited by the present invention. In addition, conventional ropes, belts, chains, etc. that are used for traction functions such as other plastic materials, rubber materials, metal materials, or flax materials can be used as the traction rope 403 of the present invention. . When selecting the traction rope 403 made of rubber, the elasticity of the rubber should be selected according to the actual situation.

Further, the driving device 30 includes a driving motor 304, a cycloidal pinwheel reducer, a horizontal double-shaft output reducer 301, a transmission belt 302, and a shaft coupling 303. The driving motor 304 and the cycloidal pinwheel reducer The connection forms a first-stage deceleration, and the output end of the cycloidal pinwheel reducer and the input end of the horizontal double-shaft output reducer 301 are connected through a transmission belt 302 to form a second-stage deceleration.

The traction rope 403 on the reel 401 can rotate counterclockwise or clockwise around the reel 401 according to actual needs, and the same reel 401 can allow the traction rope 403 to have different winding directions. When the driving motor 304 of the driving device 30 rotates forward, it drives the traction rope 403 to rotate clockwise to realize the deployment of the sunshade net 50; 50 of gathering, if the pull rope 403 on the same winding direction pays out, then the pull rope 403 on the opposite winding direction just takes up the line. Although the winding directions of the traction rope 403 on the reel 401 are different, the sunshade nets 50 on both sides of the horizontal horizontal support bar 103 are all in a synchronous unfolding or folding state.

In a preferred embodiment, the driving motor 304 is a 1.5kw four-stage vertical motor, because the rotating speed of this motor is relatively slow, and the rotating speed of the reel 401 can be reduced to 5.5r/h through one-stage deceleration and two-stage deceleration min. The low-speed rotation of the reel 401 is helpful for unexpected situations, such as the sunshade net 50 hanging on the assembled frame 10, the control device 20 can effectively control the reel 401 to stop rotating, thereby avoiding the loss of tearing the sunshade net 50.

Further, the coupling 303 is an internal tension type friction safety coupling.

The coupling 303 is divided into a rigid coupling and a flexible coupling. If the length of the reel 401 is very long, and the rotating shaft of the reel 401 and the driving device 30 cannot be guaranteed to be on the same straight line, then the rigid coupling cannot be used, but the flexible coupling can be used. The internal tension type friction safety coupling is a kind of flexible coupling, and its structure is that two identical gears 3031 are connected by a ring-shaped double-row chain 3032, and the rotating shafts of the two gears 3031 are connected with the reel 401 respectively. It is fixedly connected with the rotating shaft of the driving device 30 .

Further, referring to Fig. 1 and Fig. 5, the control device 20 includes a rainproof electrical box 201, an air switch 202, a first time controller 203 for setting the time when the sunshade net 50 is deployed, and a first time controller 203 for setting the sunshade net 50. The second time controller 204 of the time of gathering, the first limit switch 205 that is used to set the sunshade net 50 to expand the stroke, the second limit switch 206 that is used to set the sunshade net 50 to draw in the stroke, the first AC contactor 207, The second AC contactor 208, the integrated motor protector, the rainproof electric box 201 and the frame column 101 are detachably connected, the air switch 202, the first time controller 203, the second time controller 204, the first AC contactor 207. The second AC contactor 208 is set in the rainproof electrical box 201, the first limit switch 205 is set at one end of the horizontal longitudinal support bar 103, and the second limit switch 206 is set at the other end of the horizontal longitudinal support bar 103, The air switch 202 is electrically connected to the first time controller 203 and the second time controller 204 respectively, the first time controller 203 is electrically connected to the first limit switch 205, the first limit switch 205 is connected to the first The AC contactor 207 is electrically connected, and the first AC contactor 207 is electrically connected with the driving motor 304 to control the stroke of the sunshade net 50. The second time controller 204 is electrically connected with the second limit switch 206, and the second time controller 204 is electrically connected with the second limit switch 206. The limit switch 206 is electrically connected to the second AC contactor 208, and the second AC contactor 208 is electrically connected to the drive motor 304 to control the stroke of the sunshade net 50. The integrated motor protector is electrically connected to the drive motor 304, To protect the drive motor 304 from overload, leakage and phase loss.

Taking the northern part of Ningxia as an example, from June to August, the solar radiation intensity reaches about 7,500 LX at 11 am; at noon, the solar radiation intensity reaches about 160,000 LX; at 4 pm, the solar radiation intensity still reaches about 7,500 LX. During this time period, the unfolding time set by the first time controller 203 is 11:00 am, and the folding time set by the second time controller 204 is 4:00 pm.

The use process of the present invention is as follows:

When the system time reaches the time set by the first time controller 203, for example, the set time is 11 o'clock in the morning, the first time controller 203 controls the drive motor 304 to rotate forward through the first AC contactor 207, and the first The limit switch 205 is in the ON state, and the second limit switch 206 is in the OFF state. The drive motor 304 drives the reel 401 and the traction rope 403 to rotate forwardly, and under the drive of the traction rope 403, the sunshade net 50 is unfolded. When the sunshade net is deployed to contact with the position contact of the first limit switch 205, the first limit switch 205 is disconnected, and the driving motor 304 stops running; when the system time reaches the time set by the second time controller 204, for example The set time is 4 o'clock in the afternoon, and the second time controller 204 controls the reverse rotation of the drive motor 304 through the second AC contactor 208.

Compared with the shading system in the vegetable greenhouse, the outdoor shading system encounters a more complex environment, and the applicability of the device is stronger. In the open field environment, the light is stronger than in the vegetable greenhouse, and at the same time, it is more affected by the weather. Extreme weather such as strong winds and hail will greatly affect the use of the sunshade system. In such extreme weather, the vegetable greenhouse only needs to use the roller shutter machine to put down the quilt. But in an open-air environment, the shading system can only rely on itself to resist bad weather. Therefore, it is required that the device of the open-air shading system should be more reliable and the control should be more timely. The lower end of the assembled framework 10 of the sunshade system of the present invention is a concrete base with a low center of gravity, which can effectively protect the framework from being blown down when encountering strong winds. And such extreme weather as hail is usually caused by strong convection, and the wind force is also very large. The elastic force of the traction rope 403 is limited, so when the wind blows, it is not easy to lift the sunshade net 50 . As long as the sunshade net 50 is not set off, and the wind direction is all horizontal, then just as the ship puts up the sails, the wind will not have a large destructive force on the sunshade system. Thereby, the sunshade net 50 can catch the hail that falls in the sky. Below the sunshade net 50 is the traction rope 403, which can support the sunshade net 50. Because hail often occurs in summer, the speed of hail melting is also very fast, therefore can not produce long-term load to the sunshade net 50 .

At the same time, due to the uncertainty of the crops planted in the field, especially if tomatoes are planted continuously for many years, the land fertility will decrease seriously, the yield will decrease, the pests and diseases will increase, and the quality of the fruit will be poor. Therefore, rotation planting is generally required. This requires that the open field sunshade system should be easy to disassemble and transfer, so as to realize the crop rotation in the field. The assembled frame 10 of the present invention is detachable, and the rotating shaft of the driving device 30 is connected to the reel 401 of the transmission device 40 through a coupling 303, which is also detachable. The driving device 30 and the transmission device 40 are arranged on the assembled frame 10 When transferring, it is only necessary to remove the driving device 30, the transmission device 40 and the assembled frame 10 together.

The invention can realize the conversion of automatic control and manual control. When manual control is required, the air switch 202 of the control device 20 is turned off, and the forward and reverse control of the driving motor 304 is performed by using the manual switch.

The present invention is not only capable of shading tomatoes, when other open-air places need to use this shading system, such as open-air basketball courts, football fields and other open-air sports places, as well as other crop fields that need shading, etc., can use the shading system provided by the present invention. Program shade.

What is disclosed above is only a preferred embodiment of the present invention, and certainly cannot limit the scope of rights of the present invention with this. Those of ordinary skill in the art can understand the whole or part of the process of realizing the above-mentioned embodiment, and make according to the claims of the present invention The equivalent changes still belong to the scope covered by the invention.
