Description

Technical Field

[0001] The utility model belongs to the technical field of drip irrigation, in particular to a greenhouse drip irrigation device. Background Art

[0002] A drip irrigation device is a device that uses a rubber tube with a number of holes on its surface to carry out water-saving irrigation for crops within a specified range.

[0003] Among them, after searching, it was found that there is a patent number CN202020484791.0, a greenhouse vegetable irrigation dripper belt, which has a dripper patch arranged inside the dripper belt body, and is arranged by the dripper patch, the drip groove and the irrigation port. Compared with the ordinary orifice, it has high strength and is not easy to be blocked. The adhesive strip and the dustproof film are arranged to improve the protection of the dripper belt body to avoid the clogging of the irrigation port during transportation or storage. When the dripper belt is used in the greenhouse, the clamping plate is installed corresponding to the limiting protrusion, and the conical head is conveniently inserted into the soil for fixing. The clamping plate has the effect of fixing and protecting the dripper belt body; among them, the shortcomings are as follows:

[0004] When the workers use this type of greenhouse vegetable irrigation dripper belt to irrigate the crops in the greenhouse through the dripper, there is no device to effectively filter the impurities and sediments in the water resources transported to the dripper, so a large amount of water will carry the impurities and sediments directly into the dripper, which is easy to cause blockage inside the dripper and is difficult to clean. At the same time, since this type of greenhouse vegetable irrigation dripper belt only irrigates a single fixed position, it is easy for crops outside the dripper belt to not be irrigated, which may easily lead to different harvests of crops in different positions, and some crops may directly die.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the utility model:

[0022] Reference Figure 1-5 A greenhouse drip irrigation device comprises a greenhouse 1, a fixing frame A101, a slide rail 102, a fixing frame B103, a water pipe 104 and a drip pipe 4. The fixing frames A101 are fixedly installed at both ends of the top of the inner wall of the greenhouse 1, and the slide rails 102 are fixedly installed on the opposite surfaces of the bottom of the outer wall of the fixing frame A101. A drip pipe 4 is arranged on the top of the outer side of the slide rail 102, and the drip pipe 4 is arranged in a ring shape. A fixing frame B103 is fixedly installed in the middle of the bottom of the interior of the greenhouse 1, and a water pipe 104 is embedded in the rear side of the top of the inner wall of the fixing frame B103, and one end of the water pipe 104 is connected to the external water supply pipe through a matching water pump. Rotating filtering mechanisms that can filter impurities and sediments mixed in water used for drip irrigation of a large number of vegetable plants are arranged at both ends of the outer side of the fixing frame B103, and an adjustable irrigation mechanism that can freely stretch the drip pipe to adjust its own shape to expand the irrigation range is arranged at the bottom of the outer side of the slide rail 102.

[0023] Reference Figure 1 , 2 5. Further, the rotating filter mechanism is composed of a water guide frame A105, a water guide frame B106, a water guide frame C5, a filter frame 501, a filter screen plate 502, a servo motor 6 and a rotating rod 601;

[0024] Water guide frames A105 and B106 are embedded at both ends of the outer wall of the water guide pipe 104, and water guide frames B106 are fixedly installed at both ends of the bottom of the outer wall of the fixed frame B103. A water guide frame C5 is rotatably arranged between the outer walls of the water guide frames A105 and B106 through bearings. A filter frame 501 is slidably arranged in the middle of the inner side of the water guide frame C5, and the water guide frame C5 and the filter frame 501 are connected by bolts. The filter screen plate 502 is connected to the upper and lower ends of the inner wall of the filter frame 501 by bolts, and the filter screen plate 502 is arranged in an arc shape. A servo motor 6 is fixedly installed in the middle of both ends of the inner wall of the fixed frame B103, and a rotating rod 601 is connected to the outer bottom of the servo motor 6 through an output shaft, and a chain transmission is arranged between the rotating rod 601 and the water guide frame C5. When the staff needs to irrigate the greenhouse crops through a dropper , the staff turns on the water pump matched with the water pipe 104 to guide the external water source into the water guide frames A105 on both sides through the water pipe 104, and then a large amount of water is introduced into the water guide frame C5 from the other end of the water guide frame A105. At this time, the staff turns on the servo motor 6 to drive the rotating rod 601 to rotate clockwise and counterclockwise continuously, so that the rotating rod 601 drives the water guide frame C5 through the chain through the bearing transmission. When a large amount of water passes through the two surfaces of the filter screen plates 502 on the inner wall of the filter frame 501 that are continuously rotating clockwise and counterclockwise, impurities and sediments in the water will be left on the surface of the filter screen plates 502 and gather around, so that the filtered water will be introduced into the water guide frame B106, and then introduced into the dropper 4 from the water guide hose at the other end of the water guide frame B106. When a large number of crops are irrigated, the blockage of the dropper 4 caused by impurities remaining in the water can be avoided.

[0025] Reference Figure 1 , 3 4. Further, the regulating irrigation mechanism is composed of a support frame A2, an electric roller 201, a screw guide rail 3, a support frame B301, an electric telescopic rod 302, a clamping frame 303 and a dripper 401;

[0026] A support frame A2 is provided at the bottom of the outer side of the slide rail 102, and electric rollers 201 are rotatably provided on the left and right sides of both ends of the top of the outer wall of the support frame A2 through bearings, and the electric rollers 201 are slidably provided on the inner side of the slide rail 102, and screw rails 3 are fixedly installed at both ends of the inner wall of the support frame A2, and support frames B301 are slidably provided on the opposite surfaces of the outer bottom of the screw rail 3 through sliders, and electric telescopic rods 302 are fixedly installed in the middle of the opposite surfaces of the outer wall of the support frame B301, and clamping frames 303 are fixedly installed on the opposite surfaces of the outer wall bottom of the electric telescopic rod 302 and the outer wall bottom of the support frame B301, and the outer walls of the opposite surfaces of the clamping frames 303 are arranged in an arc shape, and the outer ends of the outer side of the dropper 4 are respectively arranged between the outer sides of the clamping frames 303, and a dripper 401 is embedded in the bottom of the outer wall of the dropper 4, and there are a plurality of drippers 401, which are arranged in parallel at equal distances, and The inner wall diameter of the dripper 401 is two millimeters. The dripper 4 and the other end of the outer wall of the water guide frame B106 are connected by a water guide hose. When the filtered water is introduced into the water guide frame B106, and then introduced into the dripper 4 from the water guide hose at the other end of the water guide frame B106, it is sprayed out from several drippers 401 at the bottom outside the dripper 4 to the surrounding of the crops for irrigation. At the same time, the staff controls the two screw slides 3 to drive the two ends of the dripper 4 to continuously stretch in opposite directions through the slider. After the dripper 4 is deformed into an elliptical shape, the staff turns on the servo motor matching the electric roller 201 to drive the electric roller 201 to continuously move clockwise and counterclockwise on the inner side of the ring-shaped slide 102, driving the dropper 4 stretched into an elliptical shape to continuously swing, so that the water exported from several drippers 401 is irrigated in a large range in the soil around the crops for uniform irrigation.

[0027] Reference Figure 1-4 Furthermore, the electric roller 201 is electrically connected to the battery through the matching servo motor and control panel, and the screw guide rail 3, the electric telescopic rod 302 and the servo motor 6 are all electrically connected to the battery through the control panel.

[0028] Reference Figure 1 , 3 4. Furthermore, the material of the dropper 4 is silicone rubber. Since silicone rubber has the characteristics of cold resistance and heat resistance, the inside of the dropper 4 will not be damaged due to excessive temperature difference when it is in contact with low-temperature water for a long time.

[0029] like Figure 1 , 3As shown in 4, in addition to the embodiment in which the material of the dropper 4 is silicone rubber, the utility model also has another embodiment in which the material of the dropper 4 is chloroprene rubber. Since the chloroprene rubber material has excellent cold resistance and aging resistance, the inside of the dropper 4 will not be damaged due to excessive temperature difference when it is in contact with low-temperature water for a long time. At the same time, it has the characteristics of high tensile strength, waterproofness and moisture resistance, so that the inner wall of the dropper 4 will not be damaged by moisture due to long-term contact with water.

[0030] Working principle: First, when the staff needs to irrigate the greenhouse crops through the drip tube, the staff turns on the water pump matched with the water pipe 104 to guide the external water source into the water guide frames A105 on both sides through the water pipe 104, and then a large amount of water is introduced into the water guide frame C5 from the other end of the water guide frame A105. At this time, the staff turns on the servo motor 6 to drive the rotating rod 601 to rotate clockwise and counterclockwise continuously, so that the rotating rod 601 drives the water guide frame C5 through the chain through the bearing transmission. When a large amount of water passes through the two filter screens 502 on the inner wall of the filter frame 501 that are rotating clockwise and counterclockwise, the impurities and sediments in the water will be left on the surface of the filter screen 502 and gather around. Then, the filtered water will be introduced into the water guide frame B106 and guided from the other end of the water guide frame B106. The water hose is introduced into the dropper 4. When a large number of crops are irrigated, the impurities remaining in the water can be avoided from clogging the dropper 4. Finally, a large amount of water is introduced into the dropper 4 from the water hose at the other end of the water guide frame B106, and is sprayed out from the multiple drippers 401 at the bottom outside the dropper 4 to the area around the crops. While the irrigation is being carried out, the staff controls the two screw slides 3 to drive the two ends of the dropper 4 to continuously stretch in opposite directions through the slider. After the dropper 4 is deformed into an elliptical shape, the staff turns on the servo motor matching the electric roller 201 to drive the electric roller 201 to continuously move clockwise and counterclockwise on the inner side of the ring-shaped slide 102, driving the dropper 4 stretched into an elliptical shape to continuously swing, so that the water derived from the multiple drippers 401 is irrigated in a large area in the soil around the crops for uniform irrigation.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
