Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a grain-type blower-and-seeder mechanism and agricultural machinery containing the mechanism. Background Technology

[0002] The application of small intelligent agricultural machinery offers advantages in automation and efficiency. They can perform precise sowing, fertilization, irrigation, and spraying, significantly improving agricultural production efficiency. Furthermore, small intelligent agricultural machinery is highly efficient, reducing waste of time and resources by optimizing operating routes and processes.

[0003] Currently, most seeders on the market operate on the principle of centrifugal seeding. However, when centrifugal seeders rotate at high speed, seeds may be subjected to significant centrifugal force, which can damage the seeds and affect their survival rate. Utility Model Content

[0004] One of the objectives of this invention is to provide a grain-type blower seeding mechanism that uses wind power to blow out seeds, reducing damage to seeds during sowing and thus improving seed survival rate.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a grain-type blower-driven seeding mechanism, including a seeding shell, the seeding shell having an inlet and an outlet, the seeding shell being connected to a blower, the blower being used to blow air into the seeding shell so that the seeds inside the seeding shell are blown out from the outlet under the action of the air.

[0006] Preferably, the feed inlet is located at the top of the seeding shell, the discharge outlet is located at the rear end of the seeding shell, and the blower is connected to the front end of the seeding shell.

[0007] More preferably, the feed inlet is equipped with an anti-backflow hood, the top of the anti-backflow hood is provided with an inlet for connecting to the seed dropping equipment, and the side wall of the anti-backflow hood is provided with a plurality of vent holes spaced apart. The vent holes connect the feed inlet with the outside atmosphere to discharge part of the upward backflowing wind force blown out by the blower.

[0008] More preferably, the inner diameter of the anti-backflow shroud gradually decreases from bottom to top, so that its outer peripheral surface forms a streamlined curved surface structure. The number of vent holes is four and they are evenly spaced on the outer peripheral surface of the anti-backflow shroud. The length direction of the vent holes is arranged along the streamlined curved surface, thereby forming a curved hole structure.

[0009] More preferably, the bottom of the front end of the seeding shell has an arc-shaped guide surface structure.

[0010] In addition, this utility model also provides an agricultural machine including the above-mentioned grain blowing and sowing mechanism, which includes a sowing spacing adjustment plate, two grain blowing and sowing mechanisms are movably arranged on the sowing spacing adjustment plate, and a seed drop pipe is connected to the inlet of the anti-backflow shroud, the seed drop pipe being used to connect to a seed drop device.

[0011] Preferably, two sets of sliding grooves are provided on the sowing spacing adjustment plate, and the sowing shell in the grain blower sowing mechanism is slidably connected to the corresponding sliding groove.

[0012] More preferably, a slider is fixedly connected to the side of the seeding shell, and a fastening bolt passes through the slider. One end of the fastening bolt passes through the slide groove to lock the slider at any position in the slide groove, thereby realizing the adjustment of the distance between the two grain-type blower seeding mechanisms.

[0013] Compared with existing technologies, this invention achieves uniform seed sowing by blowing air into the seeding shell using a blower. This wind-driven mechanism reduces seed damage caused by physical impact and improves seed survival rate. Moreover, using a blower as a power source reduces manufacturing and operating costs compared to other complex sowing machinery, thus improving the economics of agricultural sowing.

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0021] It should be noted in advance that, in this utility model, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Furthermore, in this utility model, unless otherwise explicitly specified and limited, "on" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features not in direct contact but through another feature between them.

[0022] like Figure 1 As shown, the grain-type blower-driven seeding mechanism includes a seeding shell 1, which has an inlet and an outlet. The seeding shell 1 is connected to a blower 2, which blows air into the seeding shell 1 to blow the seeds out of the outlet under the action of the air.

[0023] In the above structure, the feed inlet is located at the top of the seed housing 1, the discharge outlet is located at the rear end of the seed housing 1, and the blower 2 is connected to the front end of the seed housing 1. The design of the feed inlet and discharge outlet of the seed housing 1 provides a smooth flow channel for the seeds, ensuring the fluidity and uniformity of the seeds during the sowing process and preventing seed blockage and accumulation.

[0024] Furthermore, an anti-backflow hood 3 is installed at the feed inlet. The top of the anti-backflow hood 3 has an inlet for connecting to the seed-dropping equipment. The side wall of the anti-backflow hood 3 is provided with multiple vent holes 4 at intervals. The vent holes 4 connect the feed inlet to the outside atmosphere to discharge some of the upward backflowing wind force blown by the blower 2, effectively preventing wind backflow from interfering with seed sowing and preventing small seeds (such as buckwheat seeds) from being blown back by the wind, thus ensuring the uniformity and continuity of sowing. The inner diameter of the anti-backflow hood 3 gradually decreases from bottom to top, so that its outer circumference forms a streamlined curved surface structure. The number of vent holes 4 is four and they are evenly spaced on the outer circumference of the anti-backflow hood 3. The length direction of the vent holes 4 is arranged along the streamlined curved surface, thus forming a curved hole structure. This streamlined structure can reduce wind power loss and improve the efficiency of wind power utilization.

[0025] In this embodiment, the bottom of the front end of the seeding shell 1 is an arc-shaped guide surface structure, which helps to guide the seeds smoothly into the windy area and reduce the friction and damage to the seeds during the sowing process.

[0026] When the grain-producing aeration and seeding mechanism provided in the above embodiments is applied to agricultural machinery, such as... Figure 2As shown, a seeding device can be connected below the seeding equipment of agricultural machinery. A seeding spacing adjustment plate 5 is used, on which two grain-type aeration seeding mechanisms are movably mounted. The inlet of the anti-backflow cover 3 is connected to a seeding pipe 6, which connects to the seeding equipment. Through the design of the seeding spacing adjustment plate and the chutes, the spacing between the two grain-type aeration seeding mechanisms can be adjusted to meet the seeding needs of different crops, improving the flexibility and applicability of seeding. Specifically, the seeding spacing adjustment plate 5 has two sets of chutes 7, and the seeding housing 1 of the grain-type aeration seeding mechanism is slidably connected to the corresponding chutes 7. A slider 8 is fixedly connected to the side of the seeding housing 1, and a fastening bolt passes through the slider 8. One end of the fastening bolt passes through the chutes 7 to lock the slider 8 in any position within the chutes 7, thereby achieving the spacing adjustment between the two grain-type aeration seeding mechanisms. The fastening bolt design through the slider allows users to quickly adjust the seeding spacing according to actual needs, improving the adjustment speed and convenience of the seeding mechanism.

[0027] This utility model's grain-growing aeration seeding mechanism is suitable for sowing various grain crops, possessing broad adaptability and application prospects. By adjusting the forward speed of the agricultural machinery and the blowing speed of the blower, precise adjustment of seed density can be achieved to meet the needs of different crops and soil conditions, significantly improving sowing efficiency, reducing labor and material inputs, while ensuring sowing uniformity and crop growth quality. Furthermore, the blower's design allows it to maintain good sowing results under various working conditions, especially in uneven soil, maintaining sowing uniformity. More importantly, compared to commonly used centrifugal seeders, the blower design uses airflow to blow seeds, reducing seed damage during sowing and improving seed survival rate.

[0028] To facilitate understanding by those skilled in the art of the improvements of this utility model compared to the prior art, some of the accompanying drawings and descriptions of this utility model have been simplified. The above embodiments are preferred implementations of this utility model. In addition, this utility model can be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
