Description

Technical Field

[0001] This utility model relates to the field of seeding equipment technology, and in particular to a multifunctional seeding box. Background Technology

[0002] The seed box of a seeder is a core component in precision agriculture, responsible for the storage, metering, and orderly dispensing of seeds. It is usually made of high-strength engineering plastics or metal and includes an adjustable seed metering device inside, which can achieve single or multiple seed dispensing by adjusting the speed or negative pressure.

[0003] The existing seeder's seed box consists of two boxes fixed together by screws, with the seeding shaft inside the seed box rotating between the two boxes. Since the seed size of the same variety of seeds varies from year to year, the seeding wheel on the seeding shaft inside the seed box needs to be replaced according to the seed size. Because the design of the seed box and seeding shaft requires disassembling and reassembling both boxes to replace the seeding wheel, this design is extremely troublesome in practical applications. In order to facilitate a quicker and more convenient replacement of the seeding wheel of the seed box with the required size, we propose a multi-functional seed box. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional seeding box.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a multifunctional seeding box, comprising a lower box body, an upper box body, and a seeding shaft, wherein the upper box body is located above the lower box body, and one end of the lower box body is hinged to one end of the upper box body via a hinge; the other ends of the lower box body and the upper box body are fixed by bolts; the seeding shaft is rotatably connected between the front and rear inner walls of the lower box body; and further comprising:

[0006] Two semi-circular arc-shaped seeding plates are provided. Multiple second protrusions are fixedly connected to the end faces of the two semi-circular arc-shaped seeding plates that are close to each other. Multiple first protrusions are fixedly connected to the circumferential surface of the seeding shaft, and the multiple first protrusions are respectively matched with the multiple second protrusions. The two semi-circular arc-shaped seeding plates are fixedly installed to the seeding shaft and the two semi-circular arc-shaped seeding plates by multiple screws passing through the second protrusions and threaded into the multiple first protrusions. Multiple seed receiving grooves for accommodating seeds are carved on the outer surface of the two semi-circular arc-shaped seeding plates.

[0007] Preferably, a limiting block is fixedly connected to one end face of each of the two semi-circular arc-shaped seeding plates that are close to each other, and two limiting grooves are chiseled on the circumferential surface of the seeding shaft, with the two limiting blocks respectively inserted into the two limiting grooves.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] In this design, the traditional seed box is a rotating, open-type lower and upper box. The seeding shaft is installed in the lower box, and two semi-circular seeding plates are fixed to the seeding shaft with screws. The traditional seeding wheel is a ring-shaped device fixed to the seeding shaft. However, this device allows the semi-circular seeding plates to be replaced without removing the seeding shaft, eliminating the need to disassemble and assemble the two seed box bodies and the seeding shaft. This makes the operation more convenient and faster. Furthermore, since the two semi-circular seeding plates replace the traditional seeding wheel, if a semi-circular seeding plate is damaged, only one plate needs to be replaced. This avoids the drawback of replacing the entire seeding wheel if it is damaged in the traditional method, thus saving on maintenance costs. Attached Figure Description

[0014] 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.

[0015] like Figures 1-3 The multifunctional seeding box shown includes a lower box body 1, an upper box body 2, and a seeding shaft 3. The upper box body 2 is located above the lower box body 1, and one end of the lower box body 1 is hinged to one end of the upper box body 2. The other ends of the lower box body 1 and the upper box body 2 are fixed by bolts. The seeding shaft 3 is rotatably connected between the front and rear inner walls of the lower box body 1. It also includes:

[0016] Two semi-circular arc-shaped seeding plates 4 are provided, and multiple second protrusions 402 are fixedly connected to the end faces of the two semi-circular arc-shaped seeding plates 4 that are close to each other. Multiple first protrusions 302 are fixedly connected to the circumferential surface of the seeding shaft 3, and the multiple first protrusions 302 are respectively matched with the multiple second protrusions 402. The two semi-circular arc-shaped seeding plates 4 are fixedly installed by multiple screws passing through the second protrusions 402 and threaded into the multiple first protrusions 302. Multiple seed receiving grooves 401 for holding seeds are carved on the outer surface of the two semi-circular arc-shaped seeding plates 4.

[0017] When it is necessary to replace the seeding wheel in the seeding box during operation, rotate to remove the bolt between the lower box 1 and the upper box 2, rotate to open the upper box 2, rotate to remove the screws on the two semi-circular arc-shaped seeding plates 4, thereby separating the two semi-circular arc-shaped seeding plates 4 from the seeding shaft 3, take out the two semi-circular arc-shaped seeding plates 4 and replace them with two semi-circular arc-shaped seeding plates 4 of appropriate size, align the two new semi-circular arc-shaped seeding plates 4 and fasten them to wrap around the outer surface of the seeding shaft 3, then fix the seeding shaft 3 and the two semi-circular arc-shaped seeding plates 4 by rotating the screws, and finally rotate to close the upper box 2 and then rotate to tighten the bolt between the lower box 1 and the upper box 2.

[0018] In this design, the traditional seeding box is designed as a rotating open lower box 1 and an upper box 2, with the seeding shaft 3 installed inside the lower box 1. Two semi-circular arc-shaped seeding plates 4 are then fixed to the seeding shaft 3 with screws. Traditional seeding wheels are ring-shaped and fixed to the seeding shaft. However, this device design allows for the replacement of the semi-circular arc-shaped seeding plates 4 without removing the seeding shaft 3, eliminating the need to disassemble and assemble the two seeding box bodies and the seeding shaft. This makes the operation more convenient and faster. Furthermore, since the two semi-circular arc-shaped seeding plates 4 replace the traditional seeding wheel, if a semi-circular arc-shaped seeding plate 4 is damaged, only one plate needs to be replaced. This avoids the drawback of replacing the entire seeding wheel if it is partially damaged, thus saving on maintenance costs.

[0019] Specifically, two limiting grooves 301 are chiseled on the circumferential surface of the sowing shaft 3, and two limiting blocks 403 are respectively inserted into the two limiting grooves 301.

[0020] During operation, when the semi-circular arc-shaped seeding plate 4 needs to be installed on the outer surface of the seeding shaft 3, the limiting block 403 is inserted into the limiting groove 301. On the one hand, it is convenient for the semi-circular arc-shaped seeding plate 4 to be aligned with the position of the seeding shaft 3 during installation. On the other hand, the limiting block 403 inserted into the limiting groove 301 can further limit the semi-circular arc-shaped seeding plate 4.

[0021] Working principle of this utility model:

[0022] When it is necessary to replace the seeding wheel in the seed box, rotate to remove the bolt between the lower box 1 and the upper box 2, rotate to open the upper box 2, rotate to remove the screws on the two semi-circular arc-shaped seeding plates 4, thereby separating the two semi-circular arc-shaped seeding plates 4 from the seeding shaft 3. Take out the two semi-circular arc-shaped seeding plates 4 and replace them with two semi-circular arc-shaped seeding plates 4 of appropriate size. Align the two new semi-circular arc-shaped seeding plates 4 and fasten them around the outer surface of the seeding shaft 3. Then, fix the seeding shaft 3 and the two semi-circular arc-shaped seeding plates 4 by rotating the screws. Finally, rotate to close the upper box 2 and then rotate to tighten the bolt between the lower box 1 and the upper box 2.

[0023] 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.
