Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to an intelligent seeder that adapts to terrain adjustment. Background Technology

[0002] Intelligent seeders are modern agricultural equipment that integrates GPS, sensors and other technologies. They can precisely control the seeding amount, row spacing and depth, and improve seeding efficiency and uniformity. Because farmland terrain often has undulations and slopes, if the seeder is not adjusted, it is easy to cause uneven seeding. Adaptive adjustment can make the seeding parts conform to the terrain, ensure seeding quality, and improve crop emergence rate and growth consistency.

[0003] A search revealed Chinese patent (CN218789033U), which utilizes a tractor-driven mechanism. The mechanism includes a frame connected to the tractor, and a seeding bin, a covering wheel, and a pressing wheel mounted on the frame. The seeding bin is connected to a seed metering device, which includes a seed metering funnel and seed metering grooved wheels within the funnel. These grooved wheels have a degree of freedom to slide relative to the drive rod and the funnel via a transverse push rod. Multiple seed metering wheels are arranged on the grooved wheels, with the density of the seed metering grooves gradually increasing on adjacent wheels. This invention uses multiple seed metering wheels connected in series to form a set of seed metering grooved wheels. Driven by a transverse push rod, the seed metering grooved wheels are pulled in and out of the funnel, allowing seed metering wheels of different densities to enter the funnel cavity. This enables dynamic adjustment of the seed metering amount, providing the hardware conditions for fully utilizing land efficiency.

[0004] The aforementioned patent proposes to use multiple seed metering wheels connected in series to form a seed metering groove wheel. Driven by a horizontal push rod, the seed metering groove wheel is pulled in and out of the seed metering funnel, allowing seed metering wheels of different densities to enter the funnel cavity of the seed metering funnel. The aforementioned patent requires manual assistance, and the terrain of farmland often has undulations and slopes, which will affect its sowing effect and increase its sowing difficulty.

[0005] To this end, we propose an intelligent seeder that can adapt to different farmland terrains and is automated, reducing the need for manual adaptive terrain adjustment. Utility Model Content

A connecting pipe 22 is provided on the right side of the seed placement box 21 to guide the seeds to subsequent components. A strainer 23 is provided inside the seed placement box 21 to filter impurities and broken seeds. An opening and closing plate 24 is rotatably connected to the top of the seed placement box 21, which can rotate around the connecting shaft to open and close the box opening. A funnel 25 is provided at the end of the connecting pipe 22 to temporarily store seeds and prevent seeds from spilling. A conveying pipe 26 is provided at the bottom of the funnel 25 to accurately convey seeds into the trench.

[0028] The double rocker arm track assembly 4 includes two rotating wheels 41, which can rotate under the drive of the drive device 1. The two rotating wheels 41 are located on the drive end of the drive device 1 and receive the power transmitted by the drive device 1. The two rotating wheels 41 are fitted with a drive track 42 with anti-slip texture to increase friction with the ground. The drive device 1 is provided with multiple pulleys 43 to help support the drive track 42 and reduce its movement resistance.

[0029] The pulley 43 is externally rotatably connected to the inner side of the drive track 42 and rotates synchronously with the drive track 42. The driven wheel 44 is provided on the outside of the rotating wheel 41 and can rotate synchronously with the rotating wheel 41. The driven wheel 44 is sleeved on the outside of the rocker arm connecting the track 45, which is used to transmit power between the driven wheel 44 and the power unit 46. The power unit 46 is provided on the inner side of the rocker arm connecting the track 45, which can output power to adjust its tension and angle, so that the drive track 42 always keeps in contact with the terrain surface and ensures that the whole machine travels smoothly in undulating and sloping terrain.

[0030] Example 2

[0031] Please see Figures 3-5 The trenching component 3 includes a mounting frame 31, which provides a mounting carrier for trenching-related components. The left side of the mounting frame 31 is located on the right side of the drive device 1 to achieve a stable connection with the drive device 1. The outer side of multiple funnels 25 is located on the top inner side of the mounting frame 31 to enhance the installation stability of the funnels 25. The outer side of multiple conveying pipes 26 is located on the outside of the mounting frame 31 to ensure that the position of the conveying pipes 26 is fixed.

[0032] A linkage device 32 is provided on the top inner side of the mounting frame 31, which can synchronously drive multiple connecting rods 33 to move. Multiple connecting rods 33 are provided at the bottom of the linkage device 32, which can transmit the power of the linkage device 32 and adjust the height of the scraper 34. The scraper 34 is provided at the bottom of the connecting rods 33. The bottom has an arc-shaped structure to facilitate cutting into the soil to complete the trenching. Two iron chains 35 are provided at the bottom right side of the mounting frame 31. They have a certain degree of flexibility and can be adjusted according to the terrain undulations. They scrape and smooth the soil on both sides of the trench after sowing, realize the seed covering and surface leveling, and ensure that the seed covering thickness is uniform.

The funnel 25 temporarily stores and guides the seeds, and then the seeds fall precisely into the trench opened by the trenching component 3 through the conveying pipe 26. During this process, the mounting frame 31 of the trenching component 3 moves with the driving device 1. The linkage device 32 on the inner top of the mounting frame 31 drives the connecting rod 33 to move the scraper 34 downward. The scraper 34 contacts the ground and moves with the whole machine to complete the field trenching operation and provide trenches for seed sowing. The two iron chains 35 on the bottom right side of the mounting frame 31 of the trenching component 3 move with the whole machine. The iron chains 35 drive the filling plate 36 close to the ground. The filling plate 36 scrapes and smooths the soil on both sides of the trench after sowing, realizes seed covering and ground leveling, ensures uniform seed covering thickness, and creates suitable conditions for seed germination.

[0034] After the drive unit 1 is started, its drive end drives the rotating wheel 41 in the double rocker arm track assembly 4 to rotate. The rotating wheel 41 moves the whole machine through the cooperation of the drive track 42 and the pulley 43. At the same time, the rotating wheel 41 drives the driven wheel 44 to rotate. The driven wheel 44 transmits power to the power unit 46 through the rocker arm connected to the track 45. The power unit 46 drives the double rocker arm track assembly 4 to adaptively adjust the track tension and angle so that the drive track 42 always keeps in contact with the terrain surface, ensuring that the whole machine travels smoothly in undulating and sloping terrain.
