Description

Technical Field

[0001] This application relates to the field of field seeding equipment technology, specifically to a seed recovery device for a field seeder. Background Technology

[0002] Small plot seeders are primarily used in agronomy, particularly in wheat breeding experimental fields. They use a rotating seeding head to distribute seeds to all furrow openers, ensuring optimal seed distribution within the rows and enabling complete sowing of each plot without stopping, thus preventing seed mixing. Small plot seeders can control the seeding rate and area, ensuring even distribution of wheat seeds within the designated area, guaranteeing uniform seedling emergence, consistent seeding depth, and laying a solid foundation for high wheat yields. Simultaneously, they reduce the labor intensity of breeding operations and free up manpower.

[0003] Furthermore, during small-scale seeding, it is necessary to collect any remaining seeds within the seeding unit to improve resource reuse and reduce costs. However, existing seed collection structures are relatively small, making it difficult to adequately store remaining seeds. Additionally, the entire structure is integrated into the seeder, making it difficult to adjust the negative pressure. This makes it challenging to control the pressure during seed collection and cleaning, and to adjust the cleaning pressure according to the different types of remaining seeds, resulting in inconvenient operation.

[0004] Therefore, there is an urgent need for a new type of angle seat valve structure that has good sealing performance, is easy to form, has a simple structure, and is easy to disassemble and assemble. Utility Model Content

[0005] This application provides a seed recovery device for a small-area planter to solve the problems of low recovery efficiency, poor temporary storage effect, inconvenience of use, and poor applicability of existing seed recovery devices.

[0006] The technical solution adopted in this application is as follows:

[0007] This application provides a seed recycling device for a seedbed planter. The seed recycling device includes a seed box, a connecting component disposed on one side of the seed box, and a duct assembly disposed relative to the connecting component. The seed box includes a receiving part and a recycling part. The recycling part is disposed above the receiving part and is provided with a baffle. The baffle has an inclined structure and is located between the duct assembly and the connecting component.

[0008] In a preferred embodiment of this application, the connecting component includes a connecting pipe, with its two ends connected to the seed box and the seeding unit, respectively.

[0009] In a preferred embodiment of this application, the duct assembly includes a duct, a connecting part, and a solenoid valve. The connecting part is connected to the ventilation duct and the aforementioned box. The duct is connected to a ventilator. The solenoid valve controls the opening and closing of the connecting part.

[0010] In a preferred embodiment of this application, the duct assembly further includes a baffle plate connected to a solenoid valve to drive the baffle plate via the solenoid valve.

[0011] In a preferred embodiment of this application, the side wall of the recycling section is provided with a buckle, and the receiving section is provided with a mating part. The buckle and the mating part are engaged to achieve a detachable connection between the recycling section and the receiving section.

[0012] In a preferred embodiment of this application, the edge of the recycling section is provided with a guide groove, and the edge of the receiving section is provided with a protrusion, which is slidably connected to the guide groove.

[0013] In a preferred embodiment of this application, the side wall of the receiving part is provided with a handrail, and the surface is provided with an observation window.

[0014] In a preferred embodiment of this application, the surface of the baffle is provided with a mesh screen, which is elastic.

[0015] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows:

[0016] This application provides a seed recovery device. By setting a baffle structure, it prevents some residual seeds from being directly sucked into the duct assembly when recovering residual seeds from the seeding unit connected to the connecting component, thus ensuring the normal use of the duct assembly and extending its service life. Furthermore, by setting an inclined baffle, the residual seeds, after being blocked, fall into the recovery section below through the inclined structure, improving the convenience of seed recovery and reducing the situation where residual seeds fly around due to obstruction. Moreover, by setting a structure with a solenoid valve and a baffle plate, the size and opening / closing of the air outlet of the duct assembly can be adjusted. On the one hand, it can adapt to different crop seeds by adjusting the air pressure, thereby changing the suction and improving the recovery effect. On the other hand, it can disconnect the duct assembly when recovery is not needed, thereby reducing costs and making it more convenient to use. Attached Figure Description

[0025] Many specific details are set forth in the following description in order to provide a full understanding of this application.

[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0029] like Figure 1 and Figure 2 As shown, this application provides a seed recycling device for a seedbed planter. The seed recycling device includes a seed box 1, a connecting component 2 disposed on one side of the seed box 1, and a duct component 3 disposed relative to the connecting component 2. The seed box 1 includes a receiving part 11 and a recycling part 12. The recycling part 12 is disposed above the receiving part 11 and is provided with a baffle 13. The baffle 13 has an inclined structure and is located between the duct component 3 and the connecting component 2.

[0030] Among them, such as Figure 1 As shown, the overall structure of the seed box 1 can be regarded as a structure similar to a square box. The container 11 is mainly used for the passage of airflow, the flow of seed, and the guidance of seed. The container 11 is used for the residence and temporary storage of seed after recycling, so as to facilitate the subsequent removal of seed and its subsequent reuse.

[0031] As a preferred embodiment of this application, such as Figure 1 As shown, the connecting component 2 includes a connecting pipe 21, with its two ends connected to the seed box 1 and the seeding unit, respectively.

[0032] It is understandable that, for ease of explanation, this application can take corn plot sowing as an example. During sowing, some seeds will inevitably remain in the sowing unit. The setting of the connecting pipe 21 enables the sowing unit to be connected to the seed box 1, thereby facilitating the fan structure connected to the air duct assembly 3 to suck out these remaining seeds and realize the removal of the remaining seeds.

[0033] Furthermore, such as Figure 1 As shown, the duct assembly 3 includes a duct 31, a connecting part 32, and a solenoid valve 33. The connecting part 32 connects the ventilation duct 31 and the aforementioned housing 1. The duct 31 is connected to a ventilator. The solenoid valve 33 controls the opening and closing of the connecting part 32. Figure 1As shown, the duct assembly 3 also includes a baffle plate 34, which is connected to a solenoid valve 33 so as to drive the baffle plate 34 through the solenoid valve 33.

[0034] In other words, during use, if it is necessary to recycle the remaining substances, the solenoid valve 33 is energized, controlling the action of the barrier plate 34 structure, such as... Figure 1 As shown, the baffle plate 34 is vertically set and can move vertically. The solenoid valve 33 drives the baffle plate 34 to move downward, thereby opening the connection path between the air duct 31 and the connecting part 32, so that the wind can go along the connecting part 32 to the seed box 1, and drive the remaining seeds of the sowing unit connected by the connecting pipe 21 to send the remaining seeds to the seed box 1. After being blocked by the baffle 13, the remaining seeds fall into the receiving part 11, completing the removal of the remaining seeds.

[0035] Understandably, in order to ensure the blocking of the remaining seeds while also ensuring the normal passage of the airflow, the surface of the baffle 13 is provided with a mesh screen. The mesh screen is elastic, and its diameter should be smaller than that of the remaining seeds. The elastic mesh screen can block the remaining seeds while allowing them to be slightly bounced off and fall into the receiving part 11, further improving the recycling effect of the remaining seeds.

[0036] As a preferred embodiment of this application, as shown in the figure, the side wall of the recycling section 12 is provided with a buckle 14, and the receiving section 11 is provided with a mating part 15. The buckle 14 and the mating part 15 are engaged to realize the detachable connection between the recycling section 12 and the receiving section 11.

[0037] For the detachable buckle 14 and mating part 15, a simple locking buckle 14 structure available on the market can be adopted. The mating part 15 adopts a snap-fit ​​structure. The buckle 14 is inserted into the snap-fit ​​and locked by a locking pin or other structure, which ensures the reliability of use and makes disassembly more convenient, making it easier to remove the remaining parts in the receiving part 11.

[0038] Furthermore, the edge of the recycling section 12 is provided with a guide groove 18, and the edge of the receiving section 11 is provided with a protrusion 19, which is slidably connected to the guide groove 18.

[0039] It is understandable that the guide groove 18 and the protrusion 19 are designed to form a drawer-like structure between the recycling section 12 and the receiving section 11. After a certain amount of the remaining seeds are recycled, the receiving section 11 can be removed by sliding the two after unlocking, and the remaining seeds inside can be poured into other containers for temporary storage, so that they can be reused later.

[0040] Furthermore, the side wall of the receiving section 11 is provided with a handrail 17 and the surface is provided with an observation window 16. When taking out the receiving section 11, the handrail 17 provides the staff with a more comfortable grip and makes it easier to exert force; the observation window 16 makes it easier for the staff to judge whether the amount of seed inside has reached the required amount, further optimizing the user experience.
