AI Technical Summary
Traditional methods of replanting Vallisneria natans in shallow lakes with water present are ineffective because the gauze cannot decompose into pollutants, the soil balls of submerged plants scatter, and the replanting fails. Furthermore, these methods are not suitable for operations performed after the water body has been completely drained.
A replanting device comprising a feeding cylinder, a raking plate, and a fixing rod was designed. Through the cooperation of a movable handle and a spring, precise planting is achieved, ensuring that the root ball is accurately placed into the planting hole.
This method enables efficient and precise planting of Vallisneria natans, ensuring the integrity of the aquatic ecological environment and avoiding the pollution and failure risks associated with traditional methods.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the water ecological technical field, concretely relates to a shallow lake grass planting device. BACKGROUND
[0002] When the shallow lake is in the water ecological restoration management, the technology of rebuilding the water ecological system is often used, the submerged plants such as grass are planted after the water body is dredged, to restore the water ecological system. The grass growing on the riverbed is a plant that can purify water quality, play the role of balancing water ecological environment, fastening river bottom soil and preventing water and soil loss, and is beneficial to river ecological protection. After the water body management is completed, the water grass will appear the death phenomenon in the maintenance process, at this time, part of the submerged plants need to be supplemented, at this time, it is not suitable to empty the water completely and then supplement, and water operation is needed. The traditional water operation mode is throwing and throwing, that is, the submerged plant root system is wrapped with soil, and the soil ball is directly thrown into the water with gauze wrapping or directly, which brings the problem that the gauze cannot be decomposed and becomes a bottom pollution, and when directly throwing, a large amount of submerged plant soil ball will scatter, and the submerged plant will float to the water surface again, and the supplement fails. CONTENT OF THE UTILITY MODEL
[0003] To solve the above problems, the utility model discloses a shallow lake grass planting device, which is simple in structure, convenient to operate, high in grass planting rate, can realize accurate supplement and guarantee the integrity of the water ecological environment.
[0004] To achieve the above purpose, the technical scheme of the utility model is as follows:
[0005] A shallow lake grass planting device, comprising a feeding cylinder, the feeding cylinder is hollow inside, the cross section is square, the lower edge of the feeding cylinder is provided with a movable scraper, the two sides of the feeding cylinder are provided with fixed rods, the lower side of the fixed rod is provided with a movable handle, and the lower side of the movable handle is provided with a connecting rod connected to the outer side of the scraper.
[0006] As a supplement of the utility model, the movable handle and the protrusion outside the feeding cylinder are connected through a shaft pin.
[0007] As a supplement of the utility model, a spring is arranged between the fixed rod and the movable handle.
[0008] As a supplement of the utility model, the upper and lower ends of the connecting rod are movably connected with the annular rings.
[0009] As a supplement of the utility model, the scraper is triangular in shape.
[0010] As a supplement of the utility model, the upper edge of the scraper is connected with the lower edge of the feeding cylinder through a hinge.
[0011] As a supplement of the utility model, the lower side of the scraper is provided with an outward arc edge.

[0018] The device has the advantages that:
[0019] As shown in the drawings, the device has the advantages that:
[0020] When working, the feeding cylinder 1 is placed in the place where the grass needs to be planted, the palm is placed on the fixed rod 3, the fingers below hold the movable handle 4, and the spatula 2 can be pulled out by one force. Two spatulas 2 work simultaneously to dig a planting hole in the base (the river bottom soil is soft, and it is very easy to dig, so it only needs to be held for one or two times to complete), at this time, the water grass wrapped with soil balls is poured into the hole from the upper hole, the soil balls fall into the planting hole, precise planting is realized, and the planting rate is ensured.
[0021] The movable handle 4 and the protrusion outside the feeding cylinder 1 are connected through the shaft pin 6, and the movable handle 4 can be easily held and released.
[0022] The utility model discloses a spring 7 is equipped between fixed rod 3 and movable handle 4, when fixed rod 3 and movable handle 4 hold tightly, the two lower scrapers 2 will open, and it is convenient to put water grass, and when loosening, the two scrapers 2 will be attached together, and the lower part will form inverted pyramid type, and it is convenient to position when starting work.
[0023] The utility model discloses a circular ring 8 is separately arranged below movable handle 4 and the outside of scraper 2, and the upper and lower ends of connecting rod 5 can be movably connected with circular ring 8, and when holding tightly, the upper and lower ends of connecting rod can be left with angle and space, and the power can be smoothly transmitted from movable handle 4 to scraper 2.
[0024] The utility model discloses the arc edge 10 to the outside is arranged below scraper 2, and it is convenient to scrape soil to the outside.
[0025] It is to be noted that the above content only explains the technical thought of the utility model, and cannot limit the protection scope of the utility model, and for ordinary skilled person in the art, under the premise of not departing from the principle of the utility model, a plurality of improvements and refinements can be made, and the improvements and refinements all fall within the protection scope of the utility model claim.
