Description

Technical Field

[0001] This utility model relates to the field of seed metering equipment technology, and in particular to a soybean seed metering device. Background Technology

[0002] The soybean seed metering device is the core component of the seeder. It employs a precision-designed perforated wheel or air-suction system to ensure single-seed precision planting of soybeans with a diameter of 6-10mm, achieving a planting accuracy of over 98%. Its core structure includes an adjustable seed trough (adapting to different varieties and seed sizes), a flexible seed scraper (preventing multiple seeds from being trapped), and a photoelectric sensor (real-time monitoring of missed and repeated planting). Some high-end models are equipped with an electric drive frequency conversion system, which automatically adjusts the seed metering frequency (20-50 seeds / second) according to the vehicle speed. Combined with Beidou navigation, it achieves a row spacing accuracy of ±1.5cm, resulting in an operating efficiency of 10-15 mu / hour. Compared to traditional planting methods, it saves over 20% of seeds while reducing the breakage rate to below 2%, making it suitable for large-scale mechanized soybean cultivation.

[0003] The existing soybean seed metering device consists of two outer shells, a rotating shaft, and a seed metering disc. Since the size of soybeans varies from year to year, different models of seed metering discs need to be replaced according to the size of the soybeans in that year when sowing. When replacing the seed metering disc, the two outer shells need to be disassembled to remove the rotating shaft and replace the seed metering disc. After replacement, the rotating shaft and outer shell need to be reinstalled, which is very troublesome. Therefore, we propose a soybean seed metering device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a soybean seed metering device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a soybean seed metering device, comprising two outer shells and an inspection cover, the two outer shells being fixedly connected and fastened by screws, and inspection ports being cut into the two outer shells. One end of the inspection cover is rotatably hinged to the two outer shells to realize the opening and closing of the inspection port, and the other end of the inspection cover is fixedly connected to the two outer shells by bolts, and further comprising:

[0006] A rotating disk with an axle is rotatably connected between two outer shells, and a receiving groove is carved on the circumferential surface of the rotating disk with an axle.

[0007] Ten arc-shaped plates are inserted into the receiving grooves. Five of the arc-shaped plates are arranged in a row to form a ring inserted into the receiving grooves. There are two rows with the front and back tightly attached. The outer circumference of each of the ten arc-shaped plates is chiseled with multiple slots for receiving soybeans. Each of the ten arc-shaped plates is fixedly connected to the turntable with a shaft by multiple screws.

[0008] Preferably, the angle of the access ports on both of the outer casings is greater than 72 degrees.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] In this solution, five arc-shaped plates in two rows form a ring and a rotating disc with a shaft for easy disassembly and installation, thus replacing the integrated seeding disc in the traditional seed metering device. When replacing the seeding disc, only the inspection cover needs to be opened to replace the arc-shaped plates. There is no need to disassemble the seed metering device from the seeder and then disassemble and reassemble the outer shell to replace the seeding disc, making the replacement of the seeding disc more convenient and quick. At the same time, the inspection port makes it easier to observe and inspect the inside of the outer shell. Attached Figure Description

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] like Figures 1-3 The soybean seed metering device shown includes two outer shells 1 and an inspection cover 2. The two outer shells 1 are fixedly connected by screws. Inspection ports are cut into the two outer shells 1. One end of the inspection cover 2 is rotatably hinged to the two outer shells 1 to open and close the inspection ports. The other end of the inspection cover 2 is fixedly connected to the two outer shells 1 by bolts. It also includes:

[0017] A rotating disc 3 with a shaft is rotatably connected between two outer shells 1. A receiving groove 4 is carved on the circumferential surface of the rotating disc 3.

[0018] Ten curved plates 5 are inserted into the receiving groove 4. Five of the curved plates 5 are arranged in a row to form a ring inserted into the receiving groove 4. There are two rows that are closely attached to each other. The outer surface of each of the ten curved plates 5 has multiple slots 6 for holding soybeans. The ten curved plates 5 are fixed to the turntable 3 with shaft by multiple screws.

[0019] The angles of the access ports on both outer casings 1 are greater than 72 degrees.

[0020] When it is necessary to replace the arc plate 5 during operation, rotate to open the bolts on the inspection cover 2 and rotate to open the inspection cover 2. Rotate to remove the screws between the shaft turntable 3 and the arc plate 5, take the arc plate 5 out of the inspection port, insert the new arc plate 5 into the receiving groove 4 and rotate the screws to fix it to the shaft turntable 3. After all the arc plates 5 have been replaced, rotate to close the inspection cover 2 and rotate to tighten the bolts on the inspection cover 2 so that the inspection cover 2 cannot be rotated open.

[0021] In this solution, five arc-shaped plates 5 arranged in two rows form a ring and are disassembled and installed with a rotating disc 3 with a shaft, thus replacing the integrated seeding disc in the traditional seed metering device. When replacing the seeding disc, only the inspection cover 2 needs to be opened to replace the arc-shaped plates 5. There is no need to disassemble the seed metering device from the seeder and then disassemble and reassemble the outer shell 1 to replace the seeding disc, making the replacement of the seeding disc more convenient and quick. At the same time, the inspection port makes it easier to observe and inspect the inside of the outer shell 1.

[0022] Working principle of this utility model:

[0023] When the arc plate 5 needs to be replaced, rotate to open the bolts on the inspection cover 2 and rotate to open the inspection cover 2. Rotate to remove the screws between the shaft turntable 3 and the arc plate 5. Take the arc plate 5 out of the inspection port, insert the new arc plate 5 into the receiving groove 4, and rotate the screws to fix it to the shaft turntable 3. After all the arc plates 5 have been replaced, rotate to close the inspection cover 2 and rotate to tighten the bolts on the inspection cover 2 so that the inspection cover 2 cannot be rotated open.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection claimed by this utility model, which is defined by the appended claims and their equivalents.
