Description

Technical Field

[0001] This utility model relates to the technical field of air suction beam lifting machines, specifically an air suction beam lifting machine for seed selection machines. Background Technology

[0002] These are high-quality seed varieties that have undergone rigorous selection and quality testing by professional agricultural technicians to ensure that each seed possesses excellent genetic characteristics and stable growth performance. These carefully chosen seeds not only have high germination rates and strong disease resistance, but also can adapt to various climatic conditions, providing a reliable seed source for agricultural production. Whether for large-scale commercial planting or home gardening, these carefully selected high-quality seeds can help growers achieve better harvests and higher economic benefits.

[0003] Existing seed lifting machines generally use mechanical devices such as buckets combined with screw conveyors (commonly known as "augers") or chain bucket elevators to load materials. However, during the conveying process, seeds need to come into direct contact and friction with mechanical parts—the screw blades squeeze and scrape the material, or the frequent dropping and impact of the lifting buckets during circulation can easily damage the physical structure of the seeds. Utility Model Content

[0004] This utility model provides a pneumatic suction lifting beam machine for seed sorting machines, which can safely transport seeds and effectively reduce seed damage rate.

[0005] To achieve the above objectives, a pneumatic suction lifting beam machine for seed selection is provided, comprising a conveying body. An installation groove is formed on the outer wall of the conveying body near its bottom. A guide tube, which is conical, is fixedly connected to the inner wall of the conveying body near the installation groove. An installation shell is fixedly connected to the outer wall of the conveying body near the installation groove. The outer wall of the guide tube forms an angle of less than 90 degrees with the installation groove. A fan is fixedly connected to the inner surface of the installation shell. The installation shell is generally B-shaped, with a rectangular outer wall near the installation groove and a circular outer wall away from the installation groove. The fan output end is interconnected with the conveying body, and the guide tube is located above the fan output end. The installation groove is designed to connect the installation shell; the guide tube is designed to form an angle with the installation groove; the installation shell is designed to house the fan; the angle facilitates airflow; and the fan generates airflow to drive the seeds out of the discharge end.

[0006] According to the described air-suction lifting machine for seed selection, a protective shell is fixedly connected to the side surface of the mounting shell near the fan. The shape of the protective shell matches the mounting shell, and the mounting groove is rectangular. The protective shell is provided to protect the fan and to form a closed space with the mounting shell.

[0007] According to the described air-suction lifting beam machine for seed selection, the conveying body is cylindrical, with the inlet end on the side surface of the conveying body near the guide pipe and the outlet end on the side surface of the conveying body away from the inlet end. The inlet end is designed to facilitate the introduction of seeds to be conveyed, and the outlet end is designed to facilitate the discharge of seeds.

[0008] According to the aforementioned air-suction lifting machine for seed selection, the fan can guide the material to be discharged from the discharge end.

[0009] According to the described air-suction lifting machine for seed selection, a label strip is fixedly connected to the outer wall of the conveying body near the guide tube. The label strip is used to identify and distinguish the feeding end.

[0010] According to the described air-suction lifting beam machine for seed selection, a second label strip is fixedly connected to the outer wall of the conveying body near the discharge end. The second label strip is used to identify and distinguish the discharge end.

[0011] According to the pneumatic lifting machine used in the seed selection machine, the first label strip and the second label strip are different colors. The purpose of making the first and second label strips different colors is to improve their distinguishability.

[0012] According to the described air-suction lifting machine for seed selection, the mounting slot is rectangular. The rectangular design of the mounting slot is to match the rectangular portion of the mounting shell.

[0013] The beneficial effects of this invention are as follows: By starting the fan, the generated airflow is guided and accelerated out through the angle formed by the guide pipe and the mounting groove, forming a high-speed airflow in the discharge end area. In this area, the gas velocity increases and the static pressure decreases significantly, thus creating a local low-pressure zone. Simultaneously, the seeds at the feed end are in a relatively static state, and the air in this area maintains a relatively high pressure, forming a stable pressure difference with the low-pressure zone at the discharge end. Under this pressure difference, the seeds are drawn towards the low-pressure zone by the airflow and move smoothly, being continuously carried and transported by the airflow, ultimately being discharged intact and undamaged through the discharge end to the designated collection area.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figures 1 to 4 This utility model discloses a pneumatic suction lifting beam machine for a seed sorting machine, comprising a conveying body 1. An installation groove 6 is formed on the outer wall of the conveying body 1 near its bottom. A guide pipe 4, which is conical, is fixedly connected to the inner wall of the conveying body 1 near the installation groove 6. An installation shell 2 is fixedly connected to the outer wall of the conveying body 1 near the installation groove 6. The outer wall of the guide pipe 4 forms an angle of less than 90 degrees with the installation groove 6. A fan 5 is fixedly connected to the inner surface of the installation shell 2. The installation shell 2 is generally B-shaped, with a rectangular outer wall near the installation groove 6 and a circular outer wall away from the installation groove 6. The output end of the fan 5 is interconnected with the conveying body 1. The guide pipe 4 is located above the output end of the fan 5. A protective shell 3 is fixedly connected to the side surface of the installation shell 2 near the fan 5. The shape of the protective shell 3 matches that of the installation shell 2. The installation groove 6 is rectangular. Compared to the hopper-type feeding of traditional sorting machines, this device exhibits significant advantages. On the one hand, it simplifies the feeding operation, making it easy and convenient. On the other hand, the device employs a gentle conveying method, effectively reducing collisions and friction between seeds during transport, thereby preventing seed damage and ensuring seed integrity. This not only lays a solid foundation for subsequent selection processes but also, to a certain extent, guarantees seed quality and powerfully promotes the efficient and high-quality operation of the production process.

[0024] A label strip 7 is fixedly connected to the outer wall of the conveying body 1 near the guide tube 4. The fan 5 can guide the material to be discharged from the discharge end. The conveying body 1 is cylindrical. The side surface of the conveying body 1 near the guide tube 4 is the inlet end, and the side surface of the conveying body 1 away from the inlet end is the outlet end. Compared with the original fixed-location feeding method, it has now been improved to a feeding method that can be flexibly moved within a small range.

[0025] The mounting slot 6 is rectangular. The first label strip 7 and the second label strip 8 are different colors. The second label strip 8 is fixedly connected to the outer wall of the conveying body 1 near the discharge end.

[0026] Working Principle: During operation, after connecting to an external power source, the blower 5 starts and generates airflow. This airflow exits from the rectangular port of the mounting housing 2, is guided by the angle formed by the guide pipe 4 and the mounting groove 6, and is discharged, thus forming a high-speed airflow field in the area near the discharge end of the conveying body 1. The airflow velocity increases in this area, and the pressure decreases accordingly. Simultaneously, the seeds at the feed end of the conveying body 1 are relatively stationary compared to the discharge port, resulting in higher air pressure in this area and a significant pressure difference with the low-pressure area at the discharge end. Under the influence of this pressure difference, the seeds are drawn into the low-pressure area and ultimately carried by the airflow generated by the blower 5, smoothly discharged to the desired area through the discharge end.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
