Description

Technical Field

[0001] This utility model relates to the field of seed deawning technology, and in particular to a device for deawning wild forage seeds. Background Technology

[0002] Wild forage seeds often have awns attached to their surface. These awns can affect the uniformity of seed sowing, germination rate, and subsequent processing and storage. Therefore, removing the awns is a key step in the treatment of wild forage seeds.

[0003] However, existing deawning devices have many shortcomings: on the one hand, the range of action of the deawning components is not adjustable, making it difficult to adjust according to the size and awn characteristics of different varieties of forage seeds, which can easily lead to incomplete deawning or excessive damage to the seeds; on the other hand, the device lacks a pretreatment to effectively soften the awns, which makes the deawning effect affected by the toughness of the awns during the deawning process. Therefore, we propose a wild forage seed deawning device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing deawning devices, such as fixed working range of the deawning components, difficulty in adapting to different seeds, incomplete deawning or seed damage, lack of effective pretreatment and screening, low efficiency and low purity. Therefore, this invention proposes a deawning device for wild forage seeds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for removing awns from wild forage seeds includes a frame, on which a awn removal chamber is fixedly connected. The top of the awn removal chamber is fixedly connected to a storage chamber, and the bottom is fixedly connected to a filter chamber. The bottom of the filter chamber is provided with a discharge port.

[0007] The inner wall of the deawning chamber is fixedly equipped with a screen, and a deawning assembly is provided inside the screen. The deawning assembly includes a rotating roller and a plurality of deawning rods that radially penetrate the rotating roller. An adjustment assembly for driving the deawning rods to move radially is provided inside the rotating roller.

[0008] The storage silo is equipped with a spray assembly, which includes a spray pipe that runs through the storage silo. The spray pipe has multiple spray heads, and one end of the spray pipe is rotatably connected to an external water source.

[0009] In one possible design, the adjustment assembly includes two adjustment discs rotatably connected to the inner wall of the rotating roller. Each of the two adjustment discs has an arc-shaped clearance opening. Multiple adjustment rods are slidably connected to the two clearance openings on the same horizontal straight line. The deawning rods are fixedly connected to the corresponding adjustment rods in groups.

[0010] In one possible design, the adjustment assembly further includes a drive shaft with two adjustment discs passing through and fixedly connected at both ends. One end of the drive shaft extends into the interior of a connecting shaft and is fixedly fitted with a worm gear. A worm gear meshing with the worm gear is rotatably connected inside the connecting shaft, and an adjustment port for operating the worm gear is provided on the side wall of the desiccant chamber.

[0011] In one possible design, the frame is equipped with a drive assembly, including a motor and a transmission rod I. The output end of the motor is connected to the transmission rod I via a pulley I and a belt I. The transmission rod I is connected to the connecting shaft via a pulley II and a belt II.

[0012] In one possible design, the spray pipe is connected to the connecting shaft via belt III, and a diversion baffle is fixedly installed inside the storage hopper directly above the spray pipe.

[0013] In one possible design, the filter chamber is equipped with a screening component, including a screening frame and four connecting rods rotatably connected to the top of the filter chamber. The screening frame extends slidably to the outside of the filter chamber on both sides. A transmission rod II is fixedly connected to one side of the screening frame. The transmission rod II is rotatably connected to a collar via a drive rod. An eccentric wheel is rotatably arranged inside the collar, and the eccentric wheel is fixedly sleeved on the transmission rod I.

[0014] In one possible design, an air inlet is opened on one side of the filter chamber, and the air inlet is connected to an external blower; flow limiting components are symmetrically arranged inside the storage silo, including an adjusting plate that is slidably connected to the inner wall of the storage silo, one side of the adjusting plate extending to the outside of the storage silo and driven by an electric telescopic rod.

[0015] In this application, firstly, the motor is started, and the transmission rod I is driven to rotate through the belt pulley I, which drives the connecting shaft to make the rotating roller rotate at high speed in the deawning chamber. Then, the wild pasture seeds are poured into the storage silo. The seeds move downward under the action of gravity, and after being dispersed by the diversion baffle, they enter the deawning chamber for deawning. The deawning rod, which rotates with the rotating roller, contacts the seeds and removes the awns.

[0016] During the process, the spraying component works. Specifically, the spraying pipe, which is connected to an external water source, sprays water mist to pre-treat the seeds, softening the awns. Furthermore, the spraying pipe rotates synchronously with the connecting shaft under the drive of belt III, ensuring that the seeds are evenly moistened.

[0017] After the awns are removed, the seeds and awns fall through the mesh of the sieve into the filter chamber and enter the screening frame. At this time, the transmission rod I rotates, and the eccentric wheel fixed to it rotates accordingly. The collar drives the drive rod to reciprocate, and the drive rod pulls the transmission rod II, causing the screening frame to reciprocate under the constraint of the connecting rod. Simultaneously, an external blower blows air into the filter chamber through the air inlet on one side. During the reciprocating motion of the screening frame, the seeds, due to their greater weight, pass through the sieve and fall through the screen, exiting through the outlet; larger impurities such as straw are intercepted inside the screening frame and discharged from one side with the movement of the screening frame; while short awns and light debris are also discharged from one side with the airflow.

[0018] During the deawning process, the electric telescopic rod can be activated, which pushes the adjusting plate to slide inside the storage bin, thereby controlling the opening of the storage bin's discharge port and thus controlling the discharge speed of the storage bin.

[0019] If the deawning intensity needs to be adjusted, the worm can be operated through the adjustment port. The worm drives the worm wheel to rotate, which in turn rotates the transmission shaft and the adjustment disc. The adjustment rod slides within the clearance port, causing the deawning rod to move radially, thereby adjusting the position of the deawning rod to suit different seeds.

[0020] Beneficial effects: The wild forage seed deawning device of this utility model, by setting an adjustable deawning component, can flexibly adjust the radial position of the deawning rod according to the characteristics of different wild forage seeds, thereby ensuring the deawning effect while effectively reducing damage to the seeds and improving the integrity of the seeds. At the same time, it can meet the deawning needs of various forage seeds.

[0021] In this utility model, the wild forage seed deawning device achieves seed pretreatment through a spray pipe that rotates synchronously with the connecting shaft in the spray assembly. Spraying and wetting the seeds before they enter the deawning chamber not only softens the awns and facilitates subsequent deawning operations, but also reduces dust generated during the deawning process and improves the working environment.

[0022] In this invention, the wild forage seed deawning device uses an electric telescopic rod to control the opening of the flow limiting component's adjustment plate, stabilizing the feed flow and preventing blockage of the deawning chamber. The screening component, linked to the drive component, can screen the seeds after deawning, separating the residual straw from the seeds and improving the purity of the seeds.

[0023] In this invention, the radial position of the awn-removing rod can be flexibly adjusted by the adjustable awn-removing component, which can effectively reduce damage to seeds while ensuring the awn-removing effect and meet the awn-removing needs of various forage seeds; the spraying component has a spray pipe that rotates synchronously with the connecting shaft to pre-treat the seeds, which can soften the awns for awn removal and reduce dust; the flow-limiting component stabilizes the feed flow and prevents clogging, while the linked screening component can improve seed purity.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] In one embodiment: Refer to Figure 1-5 A deawning device includes a frame 1, a deawning chamber 2 fixedly connected to the frame 1, a storage chamber 3 fixedly connected to the top of the deawning chamber 2, a filter chamber 4 fixedly connected to the bottom of the deawning chamber 2, a discharge port at the bottom of the filter chamber 4, a screen 5 fixedly provided on the inner wall of the deawning chamber 2, and a deawning component provided inside the deawning chamber 2 within the screen 5.

[0032] The deawning assembly includes two connecting shafts 6 located within the screen 5. A hollow rotating roller 7 is fixedly sleeved between the two connecting shafts 6. The rotating shafts on both connecting shafts 6 extend rotatably to the outside of the deawning chamber 2 and are rotatably connected to the frame 1. The rotating roller 7 slides radially through multiple deawning rods 8. An adjustment assembly for driving the deawning rods 8 to move radially is provided inside the rotating roller 7. The adjustment assembly includes two adjusting rotating disks 9 rotatably connected to the inner wall of the rotating roller 7. Each of the two adjusting rotating disks 9 has an arc-shaped clearance opening. The same adjusting rod 11 is slidably connected to two clearance openings on the two adjusting rotating disks 9 located on the same horizontal line. The multiple deawning rods 8 are divided into multiple groups and fixedly connected to the corresponding adjusting rods 11.

[0033] The adjustment assembly also includes a drive shaft 10, which is located inside the rotating roller 7. Both ends of the drive shaft 10 pass through two adjusting rotating disks 9 and are fixedly connected to them. One end of the drive shaft 10 extends into the interior of one of the connecting shafts 6 and is fixedly fitted with a worm gear 12. A worm 13 is rotatably connected inside the connecting shaft 6, and the worm 13 meshes with the worm gear 12. An adjustment port 201 is provided on the deawning chamber 2 for easy operation of the worm 13, and a sealing plate is fixedly installed inside the adjustment port 201. When it is necessary to adjust the deawning intensity to suit different seeds, the worm 13 is operated through the adjustment port 201. The worm 13 drives the worm gear 12 to rotate, causing the drive shaft 10 and the adjusting rotating disk 9 to rotate. The adjustment rod 11 slides within the clearance opening, driving the deawning rod 8 to move radially, thereby flexibly adjusting the position of the deawning rod 8. This ensures the deawning effect while effectively reducing damage to the seeds, improving seed integrity, and meeting the deawning requirements of various forage seeds.

[0034] The storage silo 3 is equipped with a spray assembly, which includes a spray pipe 22 rotatably mounted on top of the frame 1. The spray pipe 22 penetrates the storage silo 3, and multiple spray heads are radially fixedly connected to the spray pipe 22 inside the storage silo 3. One end of the spray pipe 22 is rotatably connected to an external high-pressure water source. The spray assembly also includes a flow divider 24, which is fixedly mounted inside the storage silo 3 and directly above the spray pipe 22. Belts III 23 are fixedly fitted onto the spray pipe 22 and the rotating shaft of one of the connecting shafts 6, and the two belts III 23 are connected by a drive belt III. After the seeds are poured into the storage silo 3, they move downwards under gravity and are dispersed by the flow divider 24. The spray pipe 22 sprays water mist to pre-treat the seeds, softening the awns and facilitating subsequent awn removal. The spray pipe 22 rotates synchronously with the connecting shaft 6 under the drive of the belts III 23, ensuring that the seeds are evenly moistened and reducing dust generated during awn removal, thus improving the working environment.

[0035] The storage silo 3 is symmetrically equipped with flow-limiting components. These components include an adjusting plate 25 slidably mounted on the inner wall of the storage silo 3, with the adjusting plate 25 and the diversion baffle 24 at the same horizontal level. One side of the adjusting plate 25 slides through one side of the storage silo 3 and extends to the outside of the storage silo 3. An electric telescopic rod 26 is fixedly connected to the top of the frame 1. The output end of the electric telescopic rod 26 is fixedly connected to the bottom of the adjusting plate 25 via a mounting base. Activating the electric telescopic rod 26 pushes the adjusting plate 25 to slide within the storage silo 3, controlling the opening of the discharge port of the storage silo 3 to achieve a stable feed flow and prevent blockage of the desiccant silo 2.

[0036] The frame 1 houses a drive assembly, which includes a motor 19 fixedly mounted within the frame 1 via a mounting plate and a transmission rod I 16 rotatably mounted on the frame 1. Both the output end of the motor 19 and the transmission rod I 16 are fitted with pulleys I 20, which are connected by a belt I. Pulleys II 21 are fixedly mounted on the transmission rod I 16 and on the rotating shaft of one of the connecting shafts 6, and are connected by a belt II. When the motor 19 is started, it drives the transmission rod I 16 to rotate via pulleys I 20. The transmission rod I 16, through pulleys II 21, drives the connecting shaft 6, causing the rotating roller 7 to rotate within the awn-removing chamber 2. The awn-removing rod 8, rotating along with the rotating roller 7, contacts the seeds and removes the awns.

[0037] This application can be used in the field of seed deawning technology, or in other fields applicable to this application.

[0038] In another embodiment: Reference Figure 1-4An improvement upon Embodiment 1: A wild forage seed deawning device, applied to the field of seed deawning technology, includes a screening assembly inside a filter chamber 4. The screening assembly comprises four rotatably mounted connecting rods 14 at the top of the filter chamber 4.

A screen is mounted on the screening frame 15, and both sides of the screening frame 15 slide to the outside of the filter chamber 4. A transmission rod II 18 is fixedly mounted on one side of the screening frame 15. A drive rod is rotatably connected to the transmission rod II 18. A collar is fixedly connected to one end of the drive rod, and an eccentric wheel 17 is rotatably mounted inside the collar. The eccentric wheel 17 passes through the transmission rod I 16 and is fixedly connected to the transmission rod I 16. After the awns are removed, the seeds and awns fall through the mesh of the screen 5 into the filter chamber 4 and into the screening frame 15. When the transmission rod I 16 rotates, the eccentric wheel 17 fixedly connected to it rotates accordingly. The collar rotates with the eccentric wheel 17 and drives the drive rod to move. The drive rod pulls the transmission rod II 18, causing the screening frame 15 to reciprocate under the constraint of the connecting rod 14. At the same time, the external blower blows air into the filter chamber 4 through the air inlet 401 on one side of the filter chamber 4. During the reciprocating motion of the screening frame 15, the seeds, due to their greater weight, pass through the screen of the screening frame 15 and fall out through the outlet; larger impurities such as straw are intercepted inside the screening frame 15 and discharged from one side with the movement of the screening frame 15; while short awns and light debris are also discharged from one side with the airflow.
