Description

An electric precision seeder for hilly and mountainous areas Technical Field

[0001] The present invention relates to the technical field of agricultural planting machinery and equipment, and in particular to an electric precision seeder for hilly and mountainous areas. Background Art

[0002] A seeder is a large-scale agricultural planting machine that quickly and evenly sows seeds across farmland. Compared to traditional manual sowing, a mechanical seeder is more efficient and can complete large-scale sowing operations in a shorter time, reducing farmers' labor intensity, reducing reliance on human resources, and saving both sowing time and labor costs. Furthermore, the mechanical seeder is equipped with a seed directing control system that enables precise seeding, depth control, and spacing control, ensuring even seed distribution, thereby improving crop growth consistency and yield stability.

[0003] The earliest sowing tools were manual, with farmers using simple tools. Later, with the advancement of agricultural technology, people began to develop various auxiliary sowing tools, such as seed spreaders, laying the foundation for the development of automated sowing technology. Later, with the progress of industrialization and technological development, the level of agricultural mechanization in plain areas gradually increased. The emergence of seed drills greatly improved farming efficiency, saved labor and time costs, and improved the precision and stability of sowing operations. Currently, some advanced agricultural seed drills are equipped with data collection functions, which can monitor sowing operations in real time and generate sowing data reports to assist farmers in crop management and decision-making.

[0004] However, mechanical seeders on the market are mostly used in plain areas. Since the soil in hilly and mountainous areas is highly sticky, the land is severely fragmented and mostly terraced, large agricultural machinery is not suitable for the characteristics of farmland in this area. As a result, the level of agricultural mechanization in hilly and mountainous areas is low, and the wheel hub easily sticks to the soil and slips, resulting in abnormal situations such as repeated sowing or missing seeds in one planting hole.

[0005] Therefore, how to design an intelligent quantitative seeder with simple structure, low manufacturing cost and suitable for hilly and mountainous areas is a problem that needs to be solved urgently by those skilled in the art.

[0006] Summary of the Invention

[0007] The present invention provides an electric precision seeder for hilly and mountainous areas, which solves the technical problems of low agricultural sowing mechanization level, unstable sowing accuracy and poor reliability in hilly and mountainous areas.

[0008] The present invention solves the above technical problems with the following technical solutions: an electric precision seeder for hilly and mountainous areas, comprising: a fixed frame, a seed box, a seeding wheel, a seeding motor and a controller.

[0009] The seed box is installed in the fixed frame and has a seed inlet hole on its top surface, a through seed outlet hole on its bottom surface and the adjacent rear end surface, and an axial hole on the lower side surface; the sowing wheel is located in the seed box and its outer wheel surface extends out of the seed outlet hole, the gap between the outer wheel surface of the sowing wheel and the seed outlet hole is smaller than the diameter of the seed, and a plurality of sowing grooves for quantitatively storing seeds are provided on the outer wheel surface of the sowing wheel, and the plurality of sowing grooves are spaced apart along the circumference of the sowing wheel, and a fixed wheel hole is provided in the middle of the sowing wheel; the sowing motor is fixed on the outer side surface of the seed box and its output shaft is movable through the axial hole and inserted into the fixed wheel hole; the controller is fixed on the outer side surface of the seed box and is electrically connected to the sowing motor.

[0010] The beneficial effects of the present invention are:

[0011] 1. The sowing motor drives the sowing wheel to rotate at a uniform speed. Since the outer wheel surface of the sowing wheel near the outside of the seed box extends out of the seed hole and multiple sowing grooves for quantitative seed storage are arranged at intervals along its circumference, seeds can be sown evenly on the sowing belt, avoiding missing seeds or repeated sowing in the same planting hole, thereby improving the quantitative sowing efficiency and effect of the seeder;

[0012] 2. Use the controller to control the speed of the seeding wheel and change the seeding gap on the seeding belt to meet the row spacing requirements required by the living environment of different types of vegetable seeds.

[0013] On the basis of the above technical solution, the present invention can also be improved as follows.

[0014] Furthermore, the bottom surface of the seed box is an arc surface, and the seed outlet hole is provided on the arc surface of the seed box and passes through the adjacent rear end surface.

[0015] Furthermore, it also includes an arc-shaped scraper plate, which is fixed on the arc surface of the seed box corresponding to the lower side of the seed hole, and its concave arc surface is in contact with the outer wheel surface of the seeding wheel extending out of the seed hole.

[0016] The above-mentioned method has the following further beneficial effects: the arc-shaped scraper plate is fixed on the arc surface of the seed box corresponding to the seed hole. Since the concave arc surface of the scraper plate contacts the outer wheel surface of the sowing wheel extending out of the seed hole, the excess seeds attached to the outer wheel surface of the sowing wheel can be scraped into the seed box, thereby preventing the seeds in the seed box from falling from the gap between the sowing wheel and the seed box.

[0017] Furthermore, the fixing frame includes a fixing sleeve, multiple front fixing rods and multiple rear fixing rods. The fixing sleeve is provided with multiple front fixing holes on the top surface near its front end and multiple rear fixing holes on the top surface near its rear end; the top ends of the multiple front fixing rods are respectively inserted into the multiple front fixing holes; the top ends of the multiple rear fixing rods are respectively inserted into the multiple rear fixing holes; the seed box is inserted into the fixing sleeve.

[0018] Furthermore, it also includes a trenching assembly and a covering plate, wherein the trenching assembly is provided with a plurality of plug-in holes on the top surface near its rear end; the middle part of the top surface of the covering plate is provided with a plurality of mounting holes; the bottom ends of the plurality of front fixing rods are respectively inserted into the plurality of plug-in holes; the bottom ends of the plurality of rear fixing rods are respectively inserted into the plurality of mounting holes.

[0019] Adopt above-mentioned further beneficial effect is:

[0020] 1. First, the furrowing assembly fixed to the front end of the fixed frame is sunk into the soil to create a gully to form a sowing belt. Then, the sowing wheel is used to sow a fixed amount of seeds on the sowing belt. Finally, the soil is covered on the seeds with the covering plate. This completes the three actions of furrowing, sowing, and covering. This can simplify the mechanical structure of the seeder, reduce its size and footprint, making it more suitable for sowing in hilly and mountainous areas, and improving the level of agricultural mechanization in hilly and mountainous areas.

[0021] 2. Use the multiple plug-in holes on the furrowing assembly to fasten it to multiple front fixing rods, and then use the mounting holes on the cover plate to fasten it to multiple rear fixing rods. The installation height of the furrowing assembly and the cover plate can be adjusted according to different soils and different crops, thereby improving the adaptability of the seeder.

[0022] Furthermore, the trenching assembly includes a trenching shovel and a bulldozer plate, the bulldozer plate is a trapezoidal body and its small area end is fixed to the rear end of the trenching shovel; the multiple plug-in holes are all arranged on the top surface of the trenching shovel near its rear end; the cross-section of the covering plate is an arc-shaped structure.

[0023] A further beneficial effect of the above method is that by fixing a bulldozer plate at the rear end of the trenching shovel, the excess soil produced by trenching can be pushed to both sides of the sowing belt, making it easier to cover the soil after sowing.

[0024] Furthermore, the fixing frame also includes a front connecting strip, a front buffer spring, a rear connecting strip and a rear buffer spring, the front connecting strip is located in front of the seed box and is fixed on the plurality of front fixing rods; one end of the front buffer spring is fixed on the front connecting strip and the other end thereof is in contact with the front end surface of the seed box; the rear connecting strip is located behind the seed box and is fixed on the plurality of rear fixing rods; one end of the rear buffer spring is fixed on the rear connecting strip and the other end thereof is in contact with the rear end surface of the seed box.

[0025] Adopt above-mentioned further beneficial effect is:

[0026] 1. The front connecting strip is fixed to multiple front fixing rods. Since one end of the front buffer spring is fixed to the front connecting strip and the other end is in contact with the front end surface of the seed box, the soil resistance exerted on the trenching assembly can be alleviated during trenching operations.

[0027] 2. The rear connecting strips are fixed to multiple rear fixing rods. Since one end of the rear buffer spring is fixed to the rear fixing strips and the other end is in contact with the rear end surface of the seed box, the soil resistance on the covering plate can be alleviated during the covering operation.

[0028] Furthermore, it also includes two limiting strips, both of which are arranged along the height direction perpendicular to the seed box and relatively fixed on the two opposite outer sides of the seed box; the bottom end of the fixed sleeve contacts the top end of the two limiting strips.

[0029] Furthermore, it also includes a motor housing, which is wrapped around the outer circumference of the sowing motor and fixed to the outer side of the seed box.

[0030] Furthermore, the included angle between the center extension lines of two adjacent sowing grooves is 60° to 90°. BRIEF DESCRIPTION OF THE DRAWINGS
