Description

TECHNICAL FIELD

[0001] The utility model relates to the wheat seeding technical field, specifically, especially, a wheat seeding furrow opener. BACKGROUND

[0002] In modern agricultural production, wheat is one of the important food crops, and its seeding quality directly affects the yield and quality of wheat. Precise and efficient wheat seeding is crucial to food security. In the process of wheat seeding, the furrow opener plays a key role, which needs to open a suitable channel in the soil to facilitate the seeds to fall into the soil uniformly and accurately.

[0003] The traditional seeding furrow opener has the following shortcomings:

[0004] ①Wear and tear of the furrowing component

[0005] The furrowing component of the traditional wheat seeding furrow opener often uses ordinary steel. This material is prone to severe wear and tear when facing different soil textures, especially soil containing sand and stones. For example, in some stony farmland, the tip and blade of the furrow opener will be worn out in a short time, making it difficult to maintain consistent furrowing depth and width, affecting the seeding quality, and requiring frequent replacement of components, increasing the cost of agricultural production and labor intensity.

[0006] ②Efficiency and energy consumption of furrowing

[0007] The structural design of many traditional furrow openers is not reasonable, and they are subject to a large soil resistance during furrowing. This not only leads to low furrowing efficiency, but also consumes excessive tractor power. For example, some furrow openers need to operate at a high power output when working in hard soil, which to some extent causes energy waste.

[0008] ③Uneven distribution of seeds

[0009] Traditional furrow openers lack effective seed distribution devices during seed dropping. Seeds often accumulate or are unevenly distributed in the furrow. Uneven seed distribution can lead to competition for nutrients and light during wheat growth, affecting wheat growth and development, and thus reducing wheat yield.

[0010] ④Lack of equipment protection mechanism

[0011] In actual seeding operations, there may be solid obstacles such as stones and tree roots in farmland. Traditional furrow openers lack effective protection devices when encountering these obstacles, which can cause deformation and damage to the furrow opener, and even damage the traction equipment of the seeding machine, affecting the normal operation of the seeding operation and increasing the cost of equipment maintenance and replacement.

[0012] Although some improvements have been made to the above problems existing in the wheat seeding coulters, there are still some limitations. For example, although some improved coulters solve the wear problem to some extent, they increase the cost of equipment, or improve the trenching efficiency while ignoring the uniformity of seed distribution; some coulters have simple protection measures, but cannot effectively protect their own structure when encountering larger impact force.

[0013] The present application aims to solve the problems existing in the traditional wheat seeding coulters, and provides a wheat seeding coulter with efficient trenching, wear resistance, uniform seed distribution and effective equipment protection function. Practical new type content

[0020] Preferably, the bottom of the arch-shaped trenching shovel is further fixedly installed with a wheat seed flow dividing disc.

[0021] Preferably, the wheat flow dividing disc is in an inverted V shape, fixed on the inner wall of the bottom of the arch-shaped trenching shovel, the arc surface of the wheat flow dividing disc is larger than the caliber of the seed drop opening of the seed drop tube, and the arc surface of the wheat flow dividing disc is smaller than the bottom surface of the arch-shaped trenching shovel.

[0022] Preferably, the wheat flow dividing disc is welded to the trenching tip fixing plate.

[0023] Preferably, a machine leg safety assembly is hingedly connected to the support beam, the machine leg safety assembly includes a U-shaped guard frame hingedly connected to the support beam.

[0024] The U-shaped guard plate frame front side is provided with a plurality of safety pin holes, and at least one safety pin shaft is installed in the plurality of safety pin holes;

[0025] The U-shaped guard plate frame bottom middle position is provided with a mounting hole facilitating hinged connection with a support beam, and a hinge shaft is fixedly installed in the mounting hole;

[0026] The U-shaped guard plate frame two sides are also respectively provided with a fixing plate facilitating fixed installation with a seeding machine rack, and two screw holes facilitating connection with U-shaped screws are formed in each fixing plate.

[0027] Compared with the prior art, the beneficial effects of the utility model include the following aspects:

[0028] I. Structure design of furrow opener

[0029] ① The arc-shaped furrow opener is welded with the seed dropping cylinder, and the arc-shaped seed dropping cylinder is welded with the support beam, which ensures the stability of the seed dropping cylinder on the support beam. During the seeding process, the arc-shaped seed dropping cylinder can make the seeds fall smoothly, reduce the phenomenon of seed jamming in the seed dropping cylinder, and ensure the continuity of seeding. The arc-shaped furrow opener is welded with the bottom of the seed dropping cylinder, and the arc-shaped structure conforms to the principle of soil mechanics, which can effectively reduce the resistance of soil to the furrow opener during furrowing, making the furrowing process more easy and efficient, and reducing energy consumption.

[0030] ② The furrowing tip is made of alloy steel (high manganese steel, chromium molybdenum alloy steel) or hard alloy (tungsten carbide hard alloy), which has high hardness and high wear resistance. During furrowing, it can easily cut into various hardness soils and is not easy to wear out for a long time, prolonging the service life of the furrowing tip and reducing the replacement frequency, thereby reducing the cost of agricultural production. At the same time, the furrowing tip is fixedly connected with the arc-shaped furrow opener through the furrowing tip fixing plate and the screw, which is convenient for installation, disassembly and replacement. When the furrowing tip needs to be replaced due to wear, the operation is simple and fast, and the equipment maintenance time is reduced.

[0031] ③ The wheat seed shunt disc is in inverted V shape and is fixed to the inner wall of the bottom of the arc-shaped furrow opener. The arc-shaped disc surface is larger than the diameter of the seed dropping port of the seed dropping cylinder, which can catch all the seeds falling from the seed dropping cylinder and avoid seed omission; and smaller than the bottom surface of the arc-shaped furrow opener, which does not affect the furrowing function of the furrow opener. The shunt disc can evenly sow the seeds in the furrow, avoid seed accumulation, and make the wheat seeds more evenly distributed in the furrow, which is beneficial to the growth and development of the wheat seeds, improves the emergence rate and growth quality of the wheat, and ultimately increases the yield of the wheat.

[0032] II. Device protection

[0033] The front side of the U-shaped guard frame in the safety pin protection mechanism and support beam hinged connection leg safety assembly is provided with a plurality of safety pin holes, and a safety pin shaft is installed. When the furrow opener encounters a solid obstacle, the upper part of the furrow opener has a tendency to move forward, which will give the safety pin a certain shearing force. When the shearing force exceeds a certain limit, the safety pin will break and fail. This design can effectively avoid damage to the overall structure of the furrow opener due to excessive impact force. The hinged shaft at the middle position of the bottom of the U-shaped guard frame plays a role after the safety pin breaks. The furrow opener can rotate around the hinged shaft, so that the furrow opener can buffer the impact force by rotating itself when encountering obstacle impact, avoiding damage to the furrow opener due to impact, further protecting the overall structure of the furrow opener, reducing equipment maintenance cost, and improving equipment service life and use reliability.

[0034] ②The connection convenience with the seeder frame; screw holes are formed on the fixed plates on both sides of the U-shaped guard frame, facilitating installation and fixation with the seeder frame through U-shaped screws. This design facilitates the assembly and disassembly of the furrow opener and the seeder, improving the efficiency of equipment installation and maintenance. BRIEF DESCRIPTION OF DRAWINGS

[0047] Preferably, the wheat flow dividing disc 6 is welded to the furrower tip fixed support plate 5.

[0048] Preferably, the support beam 1 is hingedly connected with a machine leg safety assembly, the machine leg safety assembly includes a U-shaped guard frame 7 hingedly connected to the support beam;

[0049] A plurality of safety pin holes 8 are formed in the front side of the U-shaped guard frame 7, and at least one safety pin shaft 9 is installed in each of the safety pin holes 8;

[0050] A mounting hole is arranged at the middle position of the bottom of the U-shaped guard frame 7, which facilitates the hinged connection with the support beam 1, and a hinge shaft 10 is fixedly installed in the mounting hole;

[0051] The two sides of the U-shaped guard frame 7 are further respectively provided with a fixing plate 11 which facilitates the fixed installation with the seeding machine frame, and two screw holes 12 which facilitate the connection with U-shaped screws are formed in each of the fixing plates.

[0052] The technical principle of the above embodiment includes the following parts:

[0053] I. Overall installation and connection

[0054] The support beam of the wheat seeding coulter is connected with the seeding machine through the machine leg safety assembly. The support beam, as the main load-bearing structure of the entire coulter, firmly installs the coulter on the seeding machine, ensuring that the coulter can run stably during the seeding operation. The seed dropping cylinder is welded at the bottom of the support beam. The backward bending arc design not only facilitates the smooth flow of seeds from the seeding machine into the seed dropping cylinder, but also to some extent reduces the jamming phenomenon of seeds during the flow process, ensuring the continuity of seed supply. The arc-shaped coulter blade is welded at the bottom of the seed dropping cylinder and works cooperatively with the seed dropping cylinder to realize the coherent operation of trenching and seeding.

[0055] II. Trenching operation process

[0056] Trenching tip into the soil and breaking the soil

[0057] When the seeding machine moves forward under the action of the traction power, the trenching tip at the front end of the arc-shaped coulter blade first contacts the soil. Since the trenching tip is made of alloy steel (high manganese steel, chromium molybdenum alloy steel) or hard alloy (tungsten carbide hard alloy), it has high hardness and good wear resistance, and can easily cut into the soil. During the process of entering the soil, the sharp shape and appropriate angle of the trenching tip enable it to effectively break the soil, creating conditions for the subsequent entry of the trenching blade into the soil. The trenching tip extrudes and pushes the soil to the two sides, while overcoming the friction and resistance of the soil, gradually penetrating the soil to the predetermined trenching depth.

[0058] Trenching effect of the arc-shaped coulter blade

[0059] As the seeding machine continues to move forward, the arc-shaped coulter blade further penetrates the soil under the guidance of the trenching tip. The design of the arc-shaped structure enables the coulter to better adapt to the mechanical properties of the soil during trenching, reducing the resistance of the soil to the coulter. The coulter turns the soil broken by the trenching tip to the two sides and above, forming a relatively stable trench in terms of width and depth. In this process, the shape and size of the arc-shaped coulter blade determine the specifications of the trench to meet the requirements of wheat seeding for trench depth and width.

[0060] III. Seed seeding process

[0061] Seed falling and splitting

[0062] The seeds fall from the seeding machine into the bottom of the arc-shaped coulter blade through the seed dropping cylinder. The wheat seed splitter located in the inner wall of the bottom of the arc-shaped coulter blade plays a role. Its inverted V-shaped structure design can evenly split the seeds falling from the seed dropping cylinder to the two sides. The arc-shaped surface of the splitter is larger than the seed dropping port diameter of the seed dropping cylinder, ensuring that all falling seeds can be caught, preventing seed omission; and smaller than the bottom surface of the arc-shaped coulter blade to ensure that it does not affect the normal trenching function of the coulter. Through the uniform splitting of the splitter, the seeds can be evenly distributed in the trench, avoiding the accumulation of seeds in one place, providing good conditions for the uniform growth of wheat.

[0063] Seeds fell to the bottom of the ditch

[0064] After being diverted, the seeds slide down the surface of the diversion plate under the influence of gravity, eventually falling evenly into the bottom of the trenches prepared by the arched furrow shovel. The even distribution of the seeds at the bottom of the trenches facilitates full contact between the seeds and the soil, allowing them to absorb water and nutrients from the soil, laying the foundation for germination and growth.

[0065] IV. Working principle of the leg safety assembly

[0066] Normal operating status

[0067] During normal sowing operations, the U-shaped guard plate frame in the leg safety assembly is securely fixed to the seeder frame via screw holes on the fixing plate. The hinge shaft at the bottom center of the U-shaped guard plate frame maintains a stable hinged connection between the furrow opener and the support beam. At this time, the safety pin shaft installed in the safety pin hole on the front side of the U-shaped guard plate frame can withstand a certain range of force, ensuring the normal operation of the furrow opener.

[0068] Protection mechanisms when encountering obstacles

[0069] When the furrow opener encounters a sturdy obstacle, its upper part experiences a forward impact force, causing it to tend to move forward. This tendency exerts a shear force on the safety pin. When the impact force exceeds the safety pin's maximum shear strength, the safety pin breaks. At this point, the furrow opener, freed from the restraint of the safety pin, can rotate around its hinge axis. This rotation effectively buffers the impact force from the obstacle, preventing severe deformation or damage from direct impact, thus protecting the overall structure of the furrow opener and ensuring that sowing operations can continue normally after the obstacle is removed.

[0070] Compared with existing technologies, this utility model has the following advantages:

[0071] I. Structural Design of the Trencher

[0072] ① The arched furrowing shovel works in conjunction with the seed-dropping cylinder, which is curved backwards and welded to the support beam. This design ensures the stability of the seed-dropping cylinder on the support beam. During sowing, the curved seed-dropping cylinder allows seeds to fall smoothly, reducing the likelihood of seeds getting stuck inside and ensuring continuous sowing. The arched furrowing shovel is welded to the bottom of the seed-dropping cylinder. The arched structure conforms to the principles of soil mechanics, effectively reducing soil resistance to the shovel during furrowing, making the furrowing process easier and more efficient, and reducing energy consumption.

[0073] ②The opening tip is made of alloy steel (high manganese steel, chromium molybdenum alloy steel) or hard alloy (tungsten carbide hard alloy), which has high hardness and high wear resistance. When opening, it can easily cut into soil of various hardness, and it is not easy to wear out for a long time, prolonging the service life of the opening tip, reducing the replacement frequency, and thus reducing the cost of agricultural production. At the same time, the opening tip is fixedly connected with the arc-shaped opening shovel through the opening tip fixing support plate and the screw, and this connection method is convenient for installation, disassembly and replacement. When the opening tip needs to be replaced due to wear, the operation is simple and fast, reducing the equipment maintenance time.

[0074] ③The wheat seed shunt disc is in inverted V shape and is fixed to the inner wall of the bottom of the arc-shaped opening shovel. The arc-shaped disc surface is larger than the seed dropping port diameter of the seed dropping cylinder, which can catch all the seeds falling from the seed dropping cylinder, avoiding seed omission; and smaller than the bottom surface of the arc-shaped opening shovel, which does not affect the opening function of the opening shovel. The shunt disc can evenly sow the seeds in the opened ditch, avoid seed accumulation, make the wheat seeds more evenly distributed in the ditch, which is beneficial to the growth and development of wheat seeds, improves the emergence rate and growth quality of wheat, and finally increases the yield of wheat.

[0075] II. Equipment protection

[0076] ①Safety pin protection mechanism, the front side of the U-shaped guard frame in the hinge-connected leg safety component of the support beam is provided with a plurality of safety pin holes, and a safety pin shaft is installed. When the opening device encounters solid obstacles, the upper part of the opening device has a tendency to move forward, which will give the safety pin a certain shearing force. When the shearing force exceeds a certain limit value, the safety pin will break and fail. This design can effectively avoid damage to the overall structure of the opening device due to excessive impact force. The hinge shaft at the middle position of the bottom of the U-shaped guard frame plays a role after the safety pin breaks. The opening device can rotate around the hinge shaft, so that the opening device can buffer the impact force by rotating itself when encountering obstacle impact, avoiding damage to the opening device due to impact, further protecting the overall structure of the opening device, reducing the equipment maintenance cost, and improving the service life and reliability of the equipment.

[0077] ②Convenience of connection with the frame of the seeding machine; screw holes are provided on the fixed plates on both sides of the U-shaped guard frame, which are convenient for fixed installation with the frame of the seeding machine through U-shaped screws. This design facilitates the assembly and disassembly of the opening device and the seeding machine, improving the efficiency of equipment installation and maintenance.
