[0002] Black-headed gulls are medium-sized water birds of the Laridae family in the order Charadriiformes. They live and work in wetlands such as offshore and mudflats. They mainly feed on small fish, crustaceans, worms, insects, etc. The breeding season is from May to June. They nest in small groups in open coastal mudflats. One clutch contains 1 to 3 eggs, and occasionally up to 6 eggs.

[0003] With the continuous development of ecological civilization construction, how to increase the population of black-headed gulls is a top priority. If you want to increase the population of black-headed gulls, you must first ensure that the number of black-headed gull breeding nests is increased and the birth rate of black-headed gull cubs is increased. Therefore, how to improve the habitat around the nesting sites of black-headed gull breeding grounds is the key to ensuring the population of black-headed gulls.

[0004] The Liaoning Shuangtai Estuary International Important Wetland is the world's largest breeding ground for black-headed gulls, one of the world's wetlands with intact ecosystems, and a transit station for East Asian-Australian waterfowl migration. Due to oil extraction, aquaculture and other activities in the Liaoning Shuangtai Estuary coastal wetland, the tidal flats have been severely damaged, the original saltwort community has gradually degraded, and the habitat of the black-headed gull breeding nest site has been continuously destroyed. Therefore, it is particularly important to artificially assist in improving the habitat of the black-headed gull nest site and increase the number of black-headed gull populations. Summary of the invention

[0005] The invention aims to solve the problems of complex nesting site selection, interference resistance of breeding nests and small number of nests during the breeding period of black-headed gulls.

[0006] To achieve the above-mentioned purpose, the present invention provides a micro-interference device for improving the habitat of black-headed gull nests, comprising a frame, a grass pressing wheel and a grass laying wheel are installed on the frame, and the grass pressing wheel and the grass laying wheel are connected by a transmission belt; the grass pressing wheel is an octagonal prism, and a steel bar is installed on each edge line of the octagonal prism, and the top of the steel bar is designed to be a rounded arc; three spherical cones are installed on each surface of the grass pressing wheel; The grass laying wheel is cylindrical; the grass laying wheel is made of high-strength aluminum alloy, and the surface is covered with a layer of soft polyurethane coating; a synchronous wheel is installed on the left and right of the grass laying wheel and the grass pressing wheel; A suspension is installed on the frame, a shock absorber is installed between the suspension and the frame, an automatic control system is installed on the side of the suspension, a speed control module is installed inside the automatic control system, a pressure control module is installed on the side close to the speed control module, a terrain parameter control module is installed at the bottom of the pressure control module, and a data transmission module is installed on one side of the pressure control module.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The application principle of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment 1: like Figures 1 to 7 As shown, a micro-interference device for improving the habitat of black-headed gull nesting sites includes a frame 1, which is made of stainless steel and is designed as a frame structure to provide a support frame for the entire device. A grass pressing wheel 6 and a grass laying wheel 2 are installed on the frame 1, and the distance between the grass pressing wheel 6 and the grass laying wheel 2 is 2m.

[0022] The grass pressing wheel 6 is an octagonal prism with a regular octagonal side. The length of the column is 10m, and the length of each side is 50cm. A 5cm high steel bar 7 is installed on each ridge of the octagonal prism to ensure that the height of the alkali sedge plant is higher than 5cm after work. The steel bar 7 is made of high-strength alloy steel and the surface is passivated to prevent excessive damage to the alkali sedge. The top of the steel bar 7 is designed to be a rounded arc, which can gently press the alkali sedge during the grass pressing process to make it moderate in height, retaining a certain vegetation coverage to provide concealment for the black-headed gulls, and will not hinder the activities and nesting of the black-headed gulls. Three spherical hammers 5 are installed on each surface of the grass pressing wheel 6, and the distance between each spherical hammer 5 is 3m. The spherical hammer 5 is in the shape of a semi-ellipsoid, with a vertical radius of 4.5cm and a horizontal radius of 6cm. The spherical hammer 5 can further press the alkali sedge moderately during the grass pressing process to simulate natural interference and make the alkali sedge more suitable for nesting.

[0023] The grass-laying wheel 2 is cylindrical, 10 meters long, 80 centimeters in diameter, and 5 centimeters above the ground. It is used to level the pressed Suaeda salsa plants to ensure that the Suaeda salsa is evenly distributed after the operation to prevent the bifurcated plants from scratching the black-headed gulls. The grass-laying wheel 2 is made of high-strength aluminum alloy and is covered with a layer of soft polyurethane coating to avoid scratching and damaging the Suaeda salsa during the operation.

[0024] The gear pitch of the synchronous wheel 3 is 4mm, the number of teeth is 20, and a synchronous wheel 3 is installed on each side of the grass-laying wheel 2 and the grass-pressing wheel 6. The grass-laying wheel 2 and the grass-pressing wheel 6 are connected by a conveyor belt 4 to realize the integrated operation of grass pressing and grass-laying, ensuring that the two work together.

[0025] The width of the conveyor belt 4 is 10 mm to ensure the stability and effectiveness of the transmission.

[0026] The suspension 8 is mounted on the frame 1 and is used to suspend the entire device on a tractor or other traction equipment. A shock absorber 9 is installed between the suspension 8 and the frame 1 to absorb vibration and impact during travel and protect the frame 1 and the grass pressing wheel 6 and grass laying wheel 2 thereon from damage.

[0027] An automatic control system 11 is installed on the side of the suspension 8, a speed control module 12 is installed inside the automatic control system 11, a pressure control module 13 is installed near the speed control module 12, a terrain parameter control module 14 is installed at the bottom of the pressure control module 13, and a data transmission module 15 is installed on one side of the pressure control module 13. Through the data transmission module 15 inside the automatic controller, data can be transmitted to the mobile phone terminal of the personnel, so that the personnel can control the speed of the grass pressing wheel and the grass laying wheel and control the height according to the terrain changes.

[0028] A method for using a micro-disturbance device for improving the habitat of a black-headed gull nesting site: S1. Hang the device behind the tractor, start the tractor, and make the device move along the designated route. According to the actual situation of the operation area, the height of the grass pressing wheel 6, the grass laying wheel 2 and the frame are adjusted through the automatic control system 11 to adapt to the passability requirements of different terrains; the height of the grass pressing wheel and the grass laying wheel from the ground ensures the best treatment effect on the alkali sedge.

[0029] S2. The operator inputs the terrain parameters into the data transmission module, and the data transmission module inputs the terrain parameters into the terrain parameter control module. The terrain parameter control module calculates the influence of the current terrain on the operation of the device based on the collected information, and provides the information to the pressure control module and the speed control module. The pressure control module adjusts the height and pressure of the grass pressing wheel in real time according to the terrain changes; the speed control module adjusts the speed of the grass pressing wheel and the grass laying wheel in real time according to the terrain changes.

[0030] S3. The grass pressing wheel rotates under the traction of the tractor to press down the salt-land sedge, and the spherical hammer presses out the basic nest shape on the surface of the sedge pile during the rotation. The operator needs to pay close attention to the grass pressing effect and adjust the travel speed of the device and the pressure of the grass pressing wheel in time according to the actual reaction of the sedge. For example, when it is found that the sedge is over-pressed, the travel speed can be appropriately reduced or the descent height of the grass pressing wheel can be adjusted; when the sedge is not pressed enough, the pressure can be appropriately increased or the travel speed can be increased.

[0031] S4. The grass-laying wheel is linked with the grass-pressing wheel through the synchronous wheel and the conveyor belt to level the grass surface. The rotation speed and height of the grass-laying wheel can be adjusted according to the actual situation to ensure that the salsa sedge is evenly distributed after the operation and will not scratch the black-headed gulls. The device is continuously pushed along the predetermined operation route to ensure that the salsa sedge in the entire operation area is fully and evenly treated. During the operation, it should be avoided to repeatedly roll over the same area to avoid excessive damage to the salsa sedge.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
