Abstract
Description
Technical Field
[0001] The utility model relates to a DFT deep liquid flow floating hydroponic bed and belongs to the technical field of DFT deep liquid flow floating hydroponic beds. Background Art
[0002] Hydroponics is an important branch of soilless cultivation. With the development of facility agriculture technology, new factory-based soilless cultivation technology represented by Deep Flow Technique (DFT) is becoming more and more widely used. Vegetables no longer grow in the soil, but in foam floating boards. The foam floating boards float in the hydroponic beds, which are filled with nutrient solution. The roots absorb nutrients from the clean nutrient solution. The clean vegetables produced by this technology are widely praised by consumers.
[0003] There are two main types of traditional vegetable hydroponic beds. One is to support the bed frame above the ground through a bracket or directly place the bed frame on the ground. This structure can only be built into a small hydroponic bed. For a hydroponic bed with a larger area, the amount of nutrient solution inside is large, and the structural strength of this hydroponic bed is insufficient and it is easy to deform. The other is to dig a water trough on the ground. For a hydroponic bed of several hundred meters, the excavation work is large, and the puddles left behind after the hydroponic bed is moved later are also difficult to deal with.
[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0005] In view of the deficiencies in the background technology, the utility model provides a DFT deep liquid flow floating hydroponic bed, which has high structural strength, is suitable for large-area floating hydroponic cultivation of vegetables, and is simple to assemble and easy to use.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0007] A DFT deep liquid flow floating hydroponic bed comprises a bed frame arranged on the ground surface, wherein the bed frame is a rectangular frame formed by splicing two short frames and two long frames.
[0008] The short frame and the long frame are made of stainless steel. Brick retaining walls are respectively arranged on the outer sides of the two long frames, and a bed film is laid on the inner side of the bed frame.
[0009] Furthermore, a concrete strip foundation is provided at the bottom of each side of the long frame and the brick retaining wall, and both sides of the concrete strip foundation extend beyond the side surfaces of the long frame and the brick retaining wall.
[0010] Furthermore, the bed film is made of double-layer PVC sandwich film.
[0011] Furthermore, a cushioning layer is provided in the gap between the two concrete strip foundations on the inner sides of the two long frames.
[0012] Furthermore, a plurality of frame ground fixings are provided on the inner side of the long frame along the length direction, wherein the frame ground fixings are right-angled pieces, and the long frame and the concrete strip foundation are fixed to the frame ground fixings perpendicularly to each other by self-tapping screws.
[0013] Furthermore, a corner connector is provided at the end connection of the short frame and the long frame, and the corner connector fixes the short frame and the long frame to each other through fixing bolts.
[0014] Furthermore, the outer edge of the bed membrane located on the long frame is inserted into the gap between the brick retaining wall and the long frame.
[0015] Furthermore, a retaining spring is provided at the top of the short frame and the long frame, and the retaining spring fixes the bed film on the bed frame.
[0016] Furthermore, a drainage pipe joint and a water inlet pipe joint are provided at the bottom of the hydroponic bed.
[0017] Furthermore, an underground water inlet main pipe is buried at a symmetrical center position along the length direction of the hydroponic bed, and a plurality of water inlet pipe joints are arranged on the buried water inlet main pipe. The water inlet pipe joint is laterally connected to a first water branch pipe, and the two ends of the first water branch pipe are respectively connected to a second water branch pipe, and a water outlet nozzle is provided on the inner side of the second water branch pipe.
[0018] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:
[0019] 1. As the long frame is long and close to the brick retaining wall on the outside, the strength of the bed frame is enhanced to prevent the long frame of the bed frame from being deformed under the pressure of the nutrient solution inside. At the same time, there is no need to dig grooves, and the workload is small. In addition, the bed film is a double-layer PVC sandwich film, and the physical properties of the bed film are stable within the range of -25°~65°.
[0020] 2. Evenly arrange multiple water nozzles in the hydroponic bed so that the nutrient solution circulates evenly in the hydroponic bed and the vegetables in the hydroponic bed grow uniformly.
