Description

Technical Field

[0001] The utility model relates to the field of improvement of agricultural machinery, in particular to an improved sowing device applied to agricultural machinery. Background Art

[0002] As a traditional agricultural country, my country has implemented the household contract responsibility system since the 1970s. The development of agriculture is not only closely linked to the interests of farmers, but also an important part of the country's overall poverty alleviation and well-off strategy. However, due to the continuous acceleration of my country's urbanization process, most young and middle-aged people in mountainous areas have turned to work in cities, resulting in a shortage of rural labor.

[0003] As the population settles in urban areas and the rural population declines, land abandonment (the phenomenon of suitable land being left idle and uncultivated) has emerged. To effectively address this issue, ensure production efficiency, and increase crop yields, existing technologies utilize agricultural machinery and equipment to replace traditional manual agricultural labor. This saves labor while more effectively utilizing resources and reducing the labor burden on agricultural workers. Agricultural development is of great significance to the transformation and upgrading of my country's agricultural industry. If crop yields and quality can be significantly improved, it will help ensure my country's food security and promote rural revitalization.

[0004] However, existing small agricultural machinery still faces several challenges: insufficient versatility, long periods of idle time, and limited crop production. This results in single-type agricultural equipment having short operating times and spending the majority of its time idle. This idle machinery not only fails to fully utilize its capabilities, resulting in equipment waste, but also requires additional maintenance during its idle period. Improper maintenance can lead to rust and malfunctions, potentially rendering it unusable the following year. This makes some machinery consumable, requiring repeated purchases and repairs, resulting in poor economic returns.

[0005] In addition, regarding the problem of insufficient versatility, most small agricultural machinery under existing technologies cannot fully adapt to different environmental conditions and working conditions, and cannot meet the free switching requirements of different functions. Different manual labor and agricultural machinery are often required to cooperate to complete the work, resulting in poor efficiency during plowing / seeding. For example, when sowing, manual operation can only sow in a single row, and it is difficult to adjust the depth of soil burial. Due to its structure, the sowing machinery under existing technologies cannot ensure that it always maintains an appropriate distance from the soil surface. These defects either increase labor intensity or require replacement of sowing parts, thereby increasing production costs.

[0006] And it can meet the needs of sowing multiple rows at the same time. In addition, we have also designed a cantilever that can adjust the depth of soil penetration to ensure that the sowing mechanism always maintains a suitable distance from the soil surface, which has a wider range of applications. Utility Model Content

[0007] In order to solve the above problems, the present invention provides a seeding device for agricultural machinery, which can meet the needs of simultaneous sowing of multiple rows while solving the problem of the inability to adjust the depth of soil penetration under the existing technology. In addition, the present invention can also ensure that the seeding mechanism always maintains an appropriate distance from the soil surface. The present invention is easy to install and disassemble, and has a high degree of adaptability to various small agricultural machinery, with a wider range of applications. The present invention is a seeding device for agricultural machinery, and its specific structure is as follows:

[0008] A sowing device used in agricultural machinery includes an agricultural vehicle that can travel in the field, and is characterized by:

[0009] The agricultural vehicle is fixed with an L-shaped connecting plate at both ends of the front of the vehicle, and a U-shaped bracket is fixed on the horizontal plate surface above the connecting plate, and a cantilever bracket is provided on the U-shaped bracket and is obliquely downwardly arranged toward the front of the agricultural vehicle;

[0010] The cantilever bracket is divided into two sections. The section close to the U-shaped bracket is an extension section extending forward from the connecting plate, and the other section is a connecting section arranged obliquely downward in front of the agricultural vehicle. Square mounting holes are provided at the front ends of the two connecting sections, through which the sowing assembly is horizontally arranged.

[0011] An electric push rod is provided at the junction of the extension section and the connecting section. The upper end of the electric push rod is connected to the lower part of the junction of the extension section and the connecting section, and the lower end is connected to the outer side of the vertical plate surface of the connecting plate. The electric push rod supports the cantilever bracket.

[0012] According to the utility model, a sowing device applied to agricultural machinery is characterized in that there are two sowing assemblies arranged at an interval, and the sowing assembly is installed at the front end of the cantilever bracket close to the ground through a sowing disc positioning shaft that passes horizontally through the square mounting hole of the cantilever bracket. The sowing assembly includes a wheel-shaped sowing disc, a disc-shaped seed feeding disc, a movable duckbill and a fixed duckbill, wherein:

[0013] The seeding tray is rollable, and 8 sets of movable duckbill and fixed duckbill are evenly spaced in a 45° ring on the outer edge of the seeding tray. A spring block is set between the movable duckbill and the fixed duckbill, and each fixed duckbill is provided with a seed outlet pipe connected to it and leading to the inner edge of the seeding tray.

[0014] An annular seed taking belt and a seed inlet are provided at the inner edge of the seeding tray, wherein the annular seed taking belt is arranged on the inner edge of the seeding tray, and 8 seed inlets are evenly spaced and arranged in a 45° ring shape on the upper part of the seed taking belt.

[0015] The seed feed tray is fixed, with a square through hole at the center of the seed feed tray, a vertical seed feed pipe at the side of the seed feed tray, and an arc-shaped seed blocking piece at the upper middle position of the internal space of the seed feed tray, and a semicircular arc-shaped seed blocking bar at the lower middle position. The seed blocking piece blocks the seeds falling from the upper seed inlet and makes them fall into both sides of the seed blocking piece. When the seeds fall into the internal space of the seed feed tray through the seed feed pipe, they are first blocked by the seed blocking bar to prevent them from falling directly into and accumulating at the lower part of the seed feed tray. As the seeds accumulate, they overflow and fall into the seed inlet at the inner edge of the sowing tray, and then pass through the seed taking belt and fall into the seed outlet pipe, and finally enter the fixed duckbill.

[0016] According to the utility model, a sowing device applied to agricultural machinery is characterized in that the movable duckbill contacts the ground and penetrates into the soil as the sowing disc rolls. At the same time, the movable duckbill is lifted upward by the pressure of the ground. As the sowing is lifted upward, the spring blocking piece arranged between the movable duckbill and the fixed duckbill is opened, and the seeds in the fixed duckbill fall into the soil and are sown.

[0017] As the agricultural vehicle moves forward, the sowing disc rotates, and the seeds fall out of the fixed duckbill at a certain interval as the vehicle moves and are sown. When the movable duckbill leaves the ground as the sowing disc continues to rotate, the movable duckbill and the spring block reset to lock the fixed duckbill, and the sowing is closed.

[0018] According to the utility model, a sowing device applied to agricultural machinery is characterized in that the seed-taking belt is provided with a plurality of seed holes, and the number of seeds falling into the seed outlet pipe below and entering the fixed duckbill is controlled by adjusting the number of seed holes.

[0019] The seed belt itself is a replaceable component. For seeds of different crops, sizes and shapes, you can choose to replace the seed belt inside to achieve sowing of different seeds and different spacings, which is in line with modern agricultural production. By adjusting the number of seed holes, 1 to 3 seeds can be sown at a time.

[0020] According to the utility model, a sowing device applied to agricultural machinery is characterized in that the shaft shape of the sowing plate positioning shaft corresponds to the size and shape of the square mounting hole of the cantilever bracket and the square through hole in the center of the seed feed plate. The sowing plate positioning shaft is inserted from the square mounting hole of the cantilever bracket on one side, then passes through the square through hole in the center of the seed feed plate, and finally extends from the square mounting hole of the cantilever bracket on the other side to fix the seed feed plate.

[0021] According to the utility model, a sowing device applied to agricultural machinery is characterized in that the stroke of the electric push rod is 30 mm to 50 mm. When the electric push rod is extended upward, the cantilever bracket rotates counterclockwise and the sowing component is lifted. When the electric push rod is shortened downward, the cantilever bracket rotates clockwise and the sowing component falls.

[0022] The electric push rod design here allows the sowing component to hover at different heights. The distance between the sowing component and the ground is adjustable, ensuring that the moving duckbill contacts the ground and the fixed duckbill can always be opened under pressure.

[0023] According to the utility model, a seeding device applied to agricultural machinery is characterized in that the side parts of the frame body of the extension section and the connecting section of the cantilever bracket are both provided with triangular steel side plates for improving strength.

[0024] The following beneficial effects are achieved by using the seeding device of the utility model applied to agricultural machinery:

DETAILED DESCRIPTION

[0033] The following further describes the technical means, creative features, objectives and effects achieved by a seeding device of the present invention applied to agricultural machinery in combination with the accompanying drawings and embodiments.

[0034] Example

[0035] like Figures 1 to 4 As shown, a sowing device for agricultural machinery includes an agricultural vehicle that can travel in the field.
