Description

Technical Field

[0001] This utility model relates to the field of Panax notoginseng cultivation technology, specifically a Panax notoginseng cultivation bed with drip irrigation structure. Background Technology

[0002] Panax notoginseng is an important traditional Chinese medicine with significant medicinal value. Its growth requires specific environmental conditions, including suitable temperature, humidity, light, and soil permeability. In actual cultivation, to improve the survival rate and yield of Panax notoginseng and reduce soil-related diseases, specially designed planting beds are typically used. Planting beds create a favorable growing environment for Panax notoginseng and facilitate centralized management, making them one of the important facilities for its cultivation.

[0003] In the design of Panax notoginseng planting beds, the irrigation system is one of the core components. Modern planting techniques widely employ drip irrigation for precision irrigation, conserving water resources and providing a stable water supply for Panax notoginseng. Typically, the drip irrigation structure of a Panax notoginseng planting bed consists of a main pipe connecting multiple drip irrigation pipes. These pipes are evenly distributed above or inside the planting bed, delivering water to each planting trough through drip holes to meet the growth needs of Panax notoginseng. While this design achieves efficient water resource utilization, it also reveals some problems in practical operation. For example, the installation location and layout of the drip irrigation pipes may hinder the harvesting of Panax notoginseng and subsequent cleaning of the planting bed, affecting planting efficiency.

[0004] Currently, the widely used drip irrigation system, with its numerous drip pipes arranged on the planting bed, not only hinders the removal of Panax notoginseng from the bed after it matures, but also increases operational complexity due to the dense pipe arrangement. Furthermore, the cleaning of the planting bed after harvesting, such as removing residual plants and cleaning the bed surface, is also affected by the drip irrigation pipes, making the cleaning process time-consuming and labor-intensive. Therefore, we propose a Panax notoginseng planting bed with a drip irrigation system. Utility Model Content

[0005] The purpose of this invention is to provide a Panax notoginseng planting bed with a drip irrigation structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A Panax notoginseng planting bed with drip irrigation structure includes a planting bed body, which serves as the main structure of the entire planting bed and is used to support and accommodate other components, providing a stable planting environment. The top of the planting bed body is provided with a top plate, and the top of the top plate has multiple placement openings arranged in a matrix. Each placement opening holds a Panax notoginseng planting pot. The bottom of the Panax notoginseng planting pot has a seepage hole, allowing excess water dripped into the Panax notoginseng planting pot to seep downwards. The planting bed body is equipped with a drip irrigation assembly.

[0008] The drip irrigation assembly includes a frame-shaped fixed plate fixedly connected to the left side of the planting bed. The frame-shaped fixed plate is provided with an adjustable support vertical plate. When it is necessary to remove the grown Panax notoginseng, the support vertical plate can be adjusted upward so that the irrigation secondary pipe, irrigation branch pipe and drip head are away from the Panax notoginseng, thereby making it easier for the staff to move the Panax notoginseng planting pot upward and thus making it easier for the staff to remove the grown Panax notoginseng. The top of the support vertical plate is provided with an irrigation main pipe. The input end of the irrigation main pipe is connected to a water inlet hose, and the water inlet hose is connected to a water supply pipe or water supply equipment.

[0009] The outer wall of the main irrigation pipe has multiple secondary irrigation pipes arranged at equal intervals. Water entering the main irrigation pipe will enter the multiple secondary irrigation pipes. The secondary irrigation pipes are located between two adjacent Panax notoginseng planting pots. The outer walls of the secondary irrigation pipes have multiple branch irrigation pipes arranged at equal intervals. The output end of the branch irrigation pipes is equipped with a drip irrigation head. Water in the secondary irrigation pipes enters the multiple branch irrigation pipes and finally drips from the drip irrigation head. The two drip irrigation heads arranged in opposite directions irrigate the two adjacent Panax notoginseng planting pots.

[0010] Preferably, the bottom of the planting bed is equipped with a drain pipe with a valve for draining water from the planting bed. Supports are provided on both the left and right sides of the bottom of the planting bed to support the planting bed and ensure its stability and the balance of the overall structure.

[0011] Preferably, the top of the top plate and the position of the placement opening are provided with an annular protrusion. The top of the annular protrusion is located below the top of the Panax notoginseng planting pot. The annular protrusion can prevent the planting soil scattered on the top plate from falling into the planting bed through the placement opening.

[0012] Preferably, the top edge of the top plate is provided with a frame, and the top of the left and right sides of the frame are provided with U-shaped clearance grooves for avoiding the irrigation secondary pipe. The frame can prevent the planting soil scattered on the top plate from falling to the ground, thereby making it easier for workers to clean up the planting soil scattered on the top plate and facilitating cleaning operations.

[0013] Preferably, the bottom of the top plate is provided with a frame-shaped positioning plate, the outer wall of which is fitted with the top of the inner wall of the planting bed to keep the top plate stable and facilitate the assembly and disassembly of the top plate.

[0014] Preferably, a support plate is placed inside the planting bed, and the top of the support plate has multiple circular holes, which are located directly below multiple placement openings. The bottom of the Panax notoginseng planting pot abuts against the top of the support plate, which supports the Panax notoginseng planting pot and does not affect the seepage of excess water from the Panax notoginseng planting pot.

[0015] Preferably, the bottom of the support plate is provided with support side plates on both the left and right sides. The bottom of the support side plates abuts against the bottom of the inner wall of the planting bed, which supports the support plate and makes it easy for the staff to remove the support plate and clean the inside of the planting bed after the Panax notoginseng planting cycle is completed.

[0016] Preferably, a positioning rod is provided through the rear side of the frame-shaped fixed plate, and a circular insertion hole a is provided on the rear side of the supporting vertical plate near the top for inserting the positioning rod, and a circular insertion hole b is provided on the rear side of the supporting vertical plate near the bottom for inserting the positioning rod. This facilitates the worker to quickly position the supporting vertical plate. When the positioning rod is inserted into the circular insertion hole a, the irrigation auxiliary pipe is close to the Panax notoginseng planting pot, and the drip irrigation head is close to the top of the Panax notoginseng planting pot, so as to carry out drip irrigation operation on the Panax notoginseng seedlings in the Panax notoginseng planting pot. When the positioning rod is inserted into the circular insertion hole b, the irrigation auxiliary pipe, irrigation branch pipe and drip irrigation head are away from the grown Panax notoginseng, so as to facilitate the worker to take out the grown Panax notoginseng.

[0017] Preferably, the drip irrigation assembly further includes a strip-shaped fixing plate fixedly connected to the right side of the planting bed. The right ends of multiple irrigation sub-pipes are connected to the strip-shaped connecting plate, allowing the multiple irrigation sub-pipes to move synchronously. The bottom of the strip-shaped connecting plate is provided with two positioning vertical rods arranged symmetrically front and back, so that the strip-shaped connecting plate can be stable and will not shake when moving up and down. The top of the strip-shaped fixing plate is provided with positioning holes for the positioning vertical rods to pass through, improving the overall stability of the drip irrigation assembly.
