Description

Technical Field

[0001] This utility model belongs to the technical field of seeding unit, specifically an air-suction double-seedling seeding unit. Background Technology

[0002] A seeder is a planting machine that uses crop seeds as the object of sowing. Seeders used for a certain type or type of crop are often named after the crop type, such as grain row seeder, corn hill seeder, cotton seeder, and pasture broadcaster. Row seeders are mainly used for sowing small seeds such as grains, vegetables, and pasture. Currently, when seeders are in operation, multiple seeders are usually installed and driven side by side. This results in a compact structure but poor maneuverability during actual driving, which affects work efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an air-suction double-seedling belt sowing unit, which solves the problem that multiple seeders installed side by side result in a compact structure, poor passability during actual travel, and thus affect work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an air-suction double-seedling sowing unit, comprising a narrow V-shaped compactor, a left unit installed on one side of the narrow V-shaped compactor, a right unit installed on the other side of the narrow V-shaped compactor, a unit connecting frame connecting the left and right units, connecting brackets rotatably mounted on both sides of the narrow V-shaped compactor via a rotating shaft, a connecting piece connected below the narrow V-shaped compactor, and a soil covering wheel rotatably mounted on the connecting bracket;

[0005] A soil-pressing wheel is rotatably mounted on the connecting bracket. Seed bins are provided on the left and right units. Support wheels and soil-opening wheels are rotatably mounted on the left and right units. A first scraper is connected to the left and right units. A second scraper is connected to the left and right units.

[0006] As a further embodiment of this utility model: the soil compaction wheel is disposed between two soil covering wheels, and the two soil covering wheels are inclined to each other to form a V-shaped structure.

[0007] As a further embodiment of this utility model: a connecting spring is connected to the connecting bracket, and one end of the connecting spring is connected to the connecting piece.

[0008] As a further embodiment of this utility model: the unit connecting frame is L-shaped in general, the left unit and the right unit are arranged alternately on the left and right sides through the unit connecting frame, and mudguards are connected to the left unit and the right unit.

[0009] As a further embodiment of this utility model: one side of the first scraper blade is arc-shaped and contacts the support wheel, and one side of the second scraper blade is beveled and contacts the soil-opening wheel.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This air-suction double-seedling sowing unit, through the setting of left unit, right unit, unit connecting frame, soil covering wheel and connecting spring, when the soil covering wheel is moving, the connecting frame swings up and down due to the steep ground. At this time, the connecting spring will deform, thereby pulling the connecting frame to prevent the swing amplitude from being too large and affecting the soil covering. The left and right units are connected by the L-shaped unit connecting frame, thus arranging the left and right units in a staggered manner. The staggered arrangement of the left and right units improves the passability and applicability of the vehicle, thereby improving the sowing efficiency.

[0012] 2. This air-suction double-seedling seeding unit is equipped with a first scraper, a second scraper, a support wheel, and a soil-opening wheel. When the support wheel and soil-opening wheel rotate, the first and second scrapers will scrape off the soil on the support wheel and soil-opening wheel respectively, thereby preventing soil adhesion from affecting the contact between the support wheel and soil-opening wheel and the ground, and avoiding soil adhesion from raising the height of the support wheel and soil-opening wheel, which would reduce the soil-opening accuracy.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-6As shown, this utility model provides a technical solution: an air-suction dual-seedling sowing unit, including a narrow V-shaped press 1, a left unit 2 installed on one side of the narrow V-shaped press 1, and a right unit 3 installed on the other side of the narrow V-shaped press 1. A unit connecting frame 4 connects the left unit 2 and the right unit 3. The unit connecting frame 4 is L-shaped in general. The left unit 2 and the right unit 3 are arranged alternately left and right through the unit connecting frame 4. Mudguards 15 are connected to the left unit 2 and the right unit 3. By alternating left and right distribution of the left unit 2 and the right unit 3, the passability of the sowing unit is improved, thereby improving the travel efficiency.

[0022] The narrow V-shaped compactor 1 has connecting brackets 5 mounted on both sides via rotating shafts. A connector 6 is connected below the narrow V-shaped compactor 1. A connecting spring 14 is connected to the connecting bracket 5. One end of the connecting spring 14 is connected to the connector 6. The elasticity of the connecting spring 14 restricts the pulling of the connecting bracket 5, allowing the soil-covering wheel 7 to adapt to soil surfaces of varying heights.

[0023] A soil covering wheel 7 is rotatably mounted on the connecting bracket 5, and a soil pressing wheel 8 is rotatably mounted on the connecting bracket 5. The soil pressing wheel 8 is positioned between the two soil covering wheels 7, and the two soil covering wheels 7 are inclined to each other to form a V-shaped structure. When the soil covering wheel 7 moves, the two V-shaped soil covering wheels 7 will gather the soil, thereby burying the seeds.

[0024] Seed bins 9 are provided on the left unit 2 and the right unit 3. Support wheels 10 and soil-opening wheels 11 are rotatably mounted on the left unit 2 and the right unit 3. A first scraper 12 and a second scraper 13 are connected to the left unit 2 and the right unit 3. One side of the first scraper 12 is arc-shaped and contacts the support wheel 10. One side of the second scraper 13 is beveled and contacts the soil-opening wheel 11. The first scraper 12 and the second scraper 13 scrape away the mud attached to the support wheel 10 and the soil-opening wheel 11, thereby preventing the mud from affecting the rolling of the support wheel 10 and the soil-opening wheel 11 and improving the driving efficiency.

[0025] The working principle of this utility model is as follows:

[0026] The left unit 2 and the right unit 3 are connected by the L-shaped unit connecting frame 4, so that the left unit 2 and the right unit 3 are staggered. The staggered arrangement of the left unit 2 and the right unit 3 improves the passability and applicability of the vehicle, thereby improving the sowing efficiency. When the covering wheel 7 is moving, the connecting bracket 5 is affected by the steep ground and swings up and down. At this time, the connecting spring 14 will deform, and the elastic force of the connecting spring 14 will pull the connecting bracket 5 to prevent the swing amplitude from being too large and affecting the covering. While moving, the first scraper 12 and the second scraper 13 will scrape the soil off the support wheel 10 and the soil-opening wheel 11 respectively.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of this patent.
