Description

Technical Field

[0001] The utility model relates to a vegetable cultivation device, belonging to the technical field of vegetable planting. Background Art

[0002] Vegetable hydroponics is a soilless cultivation technology that does not rely on traditional soil planting. Instead, it directly provides water and nutrients to the plant roots through nutrient solution. It has the advantages of saving space, saving water, and being highly controllable. A vertical planting tube is one of the common hydroponic facilities. The surface of the planting tube is equipped with multiple planting ports arranged obliquely upward, and a bottom box for storing nutrient solution is installed at the bottom of the planting tube. When the circulating pump is working, the nutrient solution in the bottom box is transported to the bottom of the planting tube, so that the nutrient solution falls from top to bottom, so as to replenish water and humidify the vegetable roots in the planting port. After the structure formed by the bottom box and the planting tube is placed on the ground, there is no gap between the bottom box and the ground. When cleaning the ground under the bottom box, the position of the structure formed by the bottom box and the planting tube needs to be repeatedly moved. For a large number of structures formed by bottom boxes and planting tubes, the workload is increased. Therefore, it is necessary to design a vegetable cultivation device that does not require repeated movement of the bottom box when cleaning the ground under the bottom box. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vegetable cultivation device to solve the problems raised in the above background technology. When cleaning the ground at the bottom of the bottom box, the utility model does not need to repeatedly move the position of the bottom box, thereby reducing the workload.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a vegetable cultivation device comprises a bottom box, the upper side of the bottom box is provided with a plurality of straight cylinders arranged from top to bottom and plugged into each other, the lowermost straight cylinder is plugged into the bottom box, the outer surface of the straight cylinder is annularly and equidistantly provided with a plurality of planting openings communicating with the straight cylinder, the planting openings are arranged obliquely upward, and a connecting pipe for connecting the liquid inlet end of a circulating pump is installed in the middle position of the bottom of the bottom box, the bottom box is provided with a ring sleeve connected and fixed to the bottom box, and the bottom of the ring sleeve is annularly and equidistantly provided with three horizontally arranged support plates, the upper surface of the support plate is provided with a first screw hole at one end away from the ring sleeve, and the upper surface of the support plate is provided with a second screw hole on the side close to the ring sleeve, the first screw hole is threadedly connected to the outer screw arranged vertically, and the second screw hole is threadedly connected to the inner screw arranged vertically, the lower end of the outer screw and the lower end of the inner screw are both provided with support foot plates, and the upper end of the outer screw and the upper end of the inner screw are both provided with knob heads.

[0005] Furthermore, a plurality of thickening blocks are installed at equal intervals in a circular shape at the bottom of the ring sleeve. The thickening blocks and the ring sleeve are an integrally formed structure. Two threaded holes are provided on the lower surface of the thickening block. Two small holes aligned with the threaded holes are provided at one end of the support plate close to the ring sleeve. Screws are inserted in the small holes, and one end of the screw passes through the small hole and is threadedly connected to the threaded hole.

[0006] Furthermore, a plug-in ring is fixedly connected to the lower end of the straight tube, and the plug-in ring and the straight tube are an integrally formed structure. The plug-in ring on one straight tube is inserted into the other straight tube, and a plug-in sleeve is installed in the middle position of the upper surface of the bottom box, and the plug-in ring on the lowest layer of the straight tube is inserted into the plug-in sleeve.

[0007] Furthermore, a drain pipe is installed at the bottom of the ring sleeve, and a plug cover is threadedly connected to the lower end of the drain pipe.

[0008] Furthermore, a liquid filling port is installed on the upper surface of the bottom box, and a top cover is threadedly connected to the upper end of the liquid filling port.

[0009] Furthermore, a threaded blind hole is provided in the middle of the upper surface of the support plate, and the lower ends of the inner screw and the outer screw are respectively threadedly connected to the threaded blind holes on the corresponding support plate.

[0010] Beneficial effects of the utility model:

[0011] 1. Insert the connecting ring on one straight tube into another straight tube to realize the connection between the two adjacent straight tubes. Similarly, complete the connection between multiple straight tubes, so as to increase the height of the planting tube formed by multiple straight tubes as needed, and connect the lower end of the planting tube formed by multiple straight tubes with the bottom box to complete the assembly of the bottom box and the planting tube formed by multiple straight tubes.

[0012] 2. A ring sleeve is mounted on the bottom box and is connected and fixed to the bottom box, so that the nutrient solution overflowing from the planting hole or from the gap between two adjacent straight cylinders is collected in the space formed by the bottom box and the ring sleeve, preventing the overflowed nutrient solution from flowing freely, which is conducive to maintaining the cleanliness of the working environment. At the same time, the collected nutrient solution is recycled and reused to reduce the waste of nutrient solution.

[0013] 3. Align one end of the support plate with the thickening block, then use screws to connect the support plate and the thickening block to complete the assembly of the support plate and the ring sleeve. The thickening block can partially increase the thickness of the ring sleeve installation screw part without increasing the thickness of the ring sleeve as a whole.

[0014] 4. Screw the outer screw and the inner screw into the first screw hole and the second screw hole respectively. With the support of the outer screw or the inner screw, a gap is created between the bottom box and the ground, which facilitates cleaning the ground under the bottom box. The support plate at the lower end of the outer screw and the support plate at the lower end of the inner screw are alternately in contact with the ground, so that the ground under the support plate can be cleaned without moving the bottom box. Ultimately, there is no need to repeatedly move the bottom box when cleaning the ground under the bottom box, thereby reducing workload. BRIEF DESCRIPTION OF THE DRAWINGS
