Description

Technical Field

[0001] This utility model relates to the field of grass seed sowing technology, specifically to a grass seed no-till reseeding machine suitable for mountain micro-topography operations. Background Technology

[0002] my country has a large area of ​​hilly and mountainous grasslands. No-till reseeding of these degraded grasslands is a key measure to restore vegetation, prevent soil erosion, and develop ecological animal husbandry. However, most of the existing no-till reseeding machines are designed for plains, and their limitations are exposed when applied to mountainous micro-topography. For example, a grassland no-till reseeding machine with patent publication number CN223007896U includes: a seeder, the seeder including a frame, a plurality of grass seed boxes on the top of the frame, a seed metering device connected below each grass seed box, a seed metering hose connected to the outlet of the seed metering device, a furrowing assembly at the rear of the frame, a soil-pressing assembly at the rear of the furrowing assembly, the furrowing assembly including a connecting shaft, a plurality of sliding sleeves slidably mounted on the connecting shaft, a furrowing device connected below each of the sliding sleeves, an adjusting spring No. 1 provided on the connecting shaft and located between the sliding sleeves, adjusting sleeves threaded to both ends of the connecting shaft, and the soil-pressing assembly including a lower... The lower pressure frame has a soil-pressing frame rotatably mounted at its bottom, and a pressing wheel rotatably mounted at the tail end of the soil-pressing frame. A first pressing spring is provided between the lower pressure frame and the soil-pressing frame. Although the furrow spacing can be adjusted by changing the compression state of the first pressing spring, the height of the furrowing wheel is fixed. This not only makes it impossible to adjust the furrow depth according to needs, but also forces the wheel to rise in areas with local surface bulges, resulting in shallow sowing or even complete removal from the ground. In low-lying areas, the wheel is buried too deep, causing the seeds to be buried at a depth unfavorable to germination, resulting in extremely uneven sowing depth and uneven seedling emergence. Therefore, there is an urgent need for a no-till reseeding machine suitable for mountain micro-topography operations. Utility Model Content

[0018] When using this utility model, the connecting frame 1 is connected to a tractor or other traction machinery. The tractor pulls the equipment to move on the ground. The furrow opener 14 can open a furrow on the ground. The grass seeds in the seed storage cylinder 15 can be transported to the sowing pipe 18 through the seed metering device 16 and the seed delivery hose 17. Then the grass seeds will fall from the sowing pipe 18 into the furrow to achieve sowing. Afterwards, the force applied to the connecting rod 21 by the second spring 22 can make the soil pressing wheel 13 stick to the ground and compact the soil. During the furrowing process of the furrow opener 14, the pre-compression of the first spring 12 can give the furrow opener 14 a constant downward pressure. When the ground is uneven or the soil hardness is uneven, the elastic system can buffer the changes and maintain a relatively stable furrowing depth to ensure the uniformity of seedling emergence. If there is a need for different trenching depths, the second motor 9-2 can be started. The second motor 9-2 drives the drive rod 9-3 to rotate, and the drive rod 9-3 drives several drive sleeves 9-4 to rotate synchronously. The drive sleeves 9-4 drive the screw 9-6 to rotate through the bevel gear pair and the linkage rod 9-5, so that the adjusting frame 8 can drive the vertical rod 10 to move up and down, thereby realizing the adjustment of the height of several trenchers 14 to meet the needs of different trenching depths. When it is necessary to adjust the trenching spacing, motor 5-1 can be started. Motor 5-1 drives screw 5-2 to rotate, so that moving block 5-3 can move back and forth, changing the position of rotating shaft 5-6 connected to it. At this time, the included angle between adjacent connecting rods 5-4 will change, and the synchronous equidistant adjustment of several sliders 3 can be achieved through rotating shaft 5-5. Slider 3 can drive connecting block 6 to move, connecting block 6 can drive support frame 7 to move, support frame 7 can drive adjusting frame 8 to move through screw 9-6 and guide rod 9-7, and adjusting frame 8 can drive trencher 14 to move through vertical rod 10 and lifting rod 11, so as to achieve synchronous equidistant adjustment between several trenchers 14.

[0019] Compared with the prior art, the beneficial effects of this specific embodiment are as follows: 1. Through the elastic connection structure of spring 12 between lifting rod 11 and adjusting frame 8, furrow opener 14 can move up and down independently. When the ground surface is uneven or the soil hardness is uneven, spring 12 can provide constant pre-pressure to buffer the impact of terrain changes, effectively maintain the relatively stable furrowing depth of furrow opener 14, and ensure the consistency of grass seed emergence. 2. With the help of the spacing adjustment mechanism 5 consisting of motor 5-1, lead screw 5-2 and connecting rod 5-4, the angle of the connecting rod 5-4 can be changed by driving the moving block 5-3, so that several sliders 3 and corresponding furrow openers 14 can move synchronously and at equal distances. This not only can quickly respond to the needs of different grass seed sowing densities, but also strictly ensure the uniformity of the spacing between adjacent furrow openers 14. 3. The height adjustment mechanism 9, composed of motor 9-2, drive rod 9-3, linkage rod 9-5 and screw 9-6, can drive all adjustment frames 8 and trench opener 14 to lift synchronously, realize centralized control of trenching depth, and flexibly adjust the depth according to grass seed particle size or soil texture during operation. 4. The protective cylinder 20 at the bottom of the adjusting frame 8 can effectively protect the screw 9-6, preventing soil from adhering to the surface of the screw 9-6 during mountain operations and causing the adjusting frame 8 to jam, thus ensuring the long-term smooth operation of the height adjustment mechanism 9.

[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
