Description

Technical Field

[0001] This utility model belongs to the field of seed separation technology of Quercus glauca bracts, specifically relating to a Quercus glauca bract and seed separation device. Background Technology

[0002] The true name of *Quercus glauca* is *Quercus spp.*, also known as purpleheart oak, green oak, flowering oak, fine-leaved oak, iron oak, and iron oak. It is an evergreen tree belonging to the Fagaceae family and the *Quercus* genus. *Quercus glauca* is an important component of evergreen broad-leaved forests, tolerates poor soil, and prefers calcium-rich soil. Its wood has excellent properties and is an important material for shuttles in the textile industry.

[0003] The bracts of the oak (Quercus glauca) contain seeds, and the bracts need to be separated from the seeds when needed.

[0004] The commonly used method for separating bracts and seeds is to use water washing and soaking. Heavier seeds sink to the bottom of the water, while lighter bracts float on the surface. However, the separation effect of this method is difficult to guarantee. Some bracts have a tight structure and require long soaking time to open. Long soaking time will affect the seeds and lead to a decrease in the germination rate of the seeds later.

[0005] Therefore, we propose a device for separating bracts and seeds of Quercus glauca. Utility Model Content

[0006] The purpose of this invention is to provide a device for separating bracts and seeds of Quercus glauca, in order to solve the problem mentioned in the background art that the existing common separation method is to separate bracts and seeds by water washing and soaking. The heavier seeds sink to the bottom of the water, while the lighter bracts float on the surface. However, the separation effect of this method is difficult to guarantee. Some bracts have a relatively tight structure and need to be soaked for a long time to open. However, long-term soaking will affect the seeds and lead to a decrease in the germination rate of the seeds later.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a device for separating bracts and seeds of Quercus glauca, comprising a base, a hammer pressing box fixedly connected to the upper surface of the base, a mounting frame provided on the surface of the hammer pressing box, and a plurality of mounting bolts threadedly connected between the mounting frame and the hammer pressing box.

[0008] A power component is fixedly connected to the side of the mounting bracket, a threaded rod is rotatably connected inside the mounting bracket, the output shaft of the power component is fixedly connected to the threaded rod, a threaded sleeve is threadedly connected to the outer surface of the threaded rod, and a mounting shell is fixedly connected to the lower surface of the threaded sleeve.

[0009] The side of the mounting shell is fixedly connected to a second power component. The output end of the second power component is eccentrically fixedly connected to a disc. A mating plate is attached to the outer surface of the disc. Several sliding columns are fixedly connected to the lower surface of the mating plate. The bottom end of the sliding column slides through and extends out of the mounting shell and is provided with a hammer pressing component.

[0010] The hammer pressing component includes a main hammer head fixedly connected to the bottom end of the sliding column and a secondary hammer head movably disposed inside the main hammer head;

[0011] The inner wall of the hammer pressing box is hinged to two material plates and two telescopic components, and the telescopic end of the telescopic component is hinged to the material plate at the same side.

[0012] A feeding hopper is fixedly connected to the inner wall of the hammer pressing box;

[0013] A washing tank is placed on the surface of the base, and the washing tank is located directly below the hopper.

[0014] The above scheme involves mounting the device on the hammer pressing chamber using a mounting bracket. The rotation of the threaded rod drives the mounting shell to reciprocate, which in turn drives the hammer pressing component to reciprocate up and down. Combined with a washing chamber, this achieves a combined operation of hammer pressing pretreatment and washing separation. The hammer pressing component quickly breaks down the bract structure, achieving initial separation of the bracts and seeds. Subsequent washing only requires a short time to complete the final separation, effectively improving separation efficiency and avoiding damage to seed activity caused by prolonged soaking. The main hammer head and a movable secondary hammer head within the main hammer head work together, and with the elastic action of springs one and two, the hammer pressure can be adaptively adjusted according to the bract characteristics, preventing seed damage and ensuring good seed quality.

[0015] In one preferred embodiment, a plurality of alignment rods are fixedly connected to the surface of the hammer pressing box, and a plurality of alignment sleeves for inserting the alignment rods are fixedly connected to the side of the mounting bracket.

[0016] Using the above solution, the alignment rod and alignment sleeve can play a positioning and guiding role when assembling the mounting frame and the hammer pressing box, ensuring that the mounting bolt holes on the mounting frame are accurately aligned with the corresponding holes on the hammer pressing box, avoiding assembly difficulties caused by hole misalignment during installation, and improving the structural stability after the mounting frame and the hammer pressing box are connected, reducing vibration displacement during hammer pressing operations.

[0017] In one preferred embodiment, the inner wall of the mounting bracket is fixed with a plurality of guide rods, and the surface of the mounting shell is fixedly connected with a plurality of guide sleeves that are slidably sleeved on the outer surface of the guide rods.

[0018] By adopting the above scheme, the sliding fit between the guide rod and the guide sleeve provides guidance for the lateral movement of the mounting shell, avoiding the rotation of the threaded rod causing the mounting shell to twist or shift, ensuring that the mounting shell and the hammer pressing parts always move smoothly along a straight line, improving the accuracy of the hammer pressing operation, and preventing uneven hammer pressing caused by the shaking of the mounting shell.

[0019] In a preferred embodiment, a spring is fitted onto the outer surface of the sliding column, and the two ends of the spring are fixedly connected to the surface of the mating plate and the inner wall of the mounting shell, respectively.

[0020] Using the above scheme, spring one provides elastic restoring force to the mating plate. When the disc rotates to the non-protruding position, spring one can pull the mating plate to quickly return to its original position, causing the sliding column and hammer pressing component to rebound upwards, realizing the reciprocating hammer pressing action of the hammer pressing component. Spring one can buffer the impact force of the disc on the mating plate, reduce rigid collisions between components, and extend the service life of the equipment.

[0021] In a preferred embodiment, a second spring and a telescopic rod are fixedly connected to the inner wall of the main hammer head, and both the second spring and the telescopic rod are fixedly connected to the secondary hammer head.

[0022] Using the above scheme, the spring and the telescopic rod enable the secondary hammer head to have an elastic buffer function. When the hammer pressing part contacts the bract, the secondary hammer head can adaptively extend and retract according to the hardness and thickness of the bract, avoiding excessive pressure from the main hammer head that directly damages the seeds. The telescopic rod can limit the extension and retraction direction of the secondary hammer head, prevent the secondary hammer head from deviating, and ensure that the hammer pressure is concentrated on the bract, thereby improving the bract breaking effect.

[0023] In a preferred embodiment, an arc-shaped slider is fixedly connected to the side of the material plate, and an arc-shaped groove is provided on the inner wall of the hammer pressing box for the arc-shaped slider to slide.

[0024] The above scheme uses the sliding cooperation between the arc-shaped slider and the arc-shaped groove to guide the hinged rotation of the material plate, ensuring that the material plate rotates smoothly along a fixed trajectory under the drive of the telescopic component, and avoiding jamming or deviation when the material plate rotates.

[0025] In a preferred embodiment, a limiting frame is fixedly connected to the surface of the base, and the washing tank is inserted into the inner wall of the limiting frame.

[0026] Using the above scheme, the limiting frame is used to position and fix the washing tank to prevent the washing tank from shifting due to vibration during equipment operation, ensuring that the material falling from the hopper falls accurately into the washing tank. The plug-in structure facilitates the placement and removal of the washing tank, and makes it convenient for subsequent collection and processing of the separated seeds and bracts.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] This Quercus glauca bract and seed separation device is mounted on a hammer pressing box via a mounting frame. The rotation of the threaded rod drives the mounting shell to reciprocate, which in turn drives the hammer pressing component to reciprocate up and down. When used in conjunction with a washing box, it achieves a combined working method of hammer pressing pretreatment and water washing separation. The hammer pressing component shell quickly breaks the bract structure, achieving the initial separation of bracts and seeds. Subsequent water washing can complete the final separation in a short time, effectively improving the separation efficiency and avoiding the damage to seed activity caused by prolonged soaking.

[0029] This Quercus glauca bract and seed separation device uses a main hammer and a secondary hammer that is movably installed inside the main hammer. With the elastic action of spring one and spring two, the hammer pressure can be adaptively adjusted according to the characteristics of the bracts to prevent the seeds from being damaged by pressure and to ensure good seed quality.

[0037] Please see Figure 1-6This utility model provides a device for separating bracts and seeds of Quercus glauca, including a base 1, a hammer pressing box 2 fixedly connected to the upper surface of the base 1, a mounting frame 3 provided on the surface of the hammer pressing box 2, and a number of mounting bolts 4 threadedly connected between the mounting frame 3 and the hammer pressing box 2. The mounting frame 3 is detachably connected to the hammer pressing box 2 through the mounting bolts 4, which facilitates later maintenance and component replacement.

[0038] The mounting bracket 3 is fixedly connected to a power component 5 on its side. The mounting bracket 3 is rotatably connected to a threaded rod 6. The output shaft of the power component 5 is fixedly connected to the threaded rod 6. The outer surface of the threaded rod 6 is threadedly connected to a threaded sleeve 7. The lower surface of the threaded sleeve 7 is fixedly connected to a mounting shell 8. The power component 5 drives the threaded rod 6 to rotate, which causes the threaded sleeve 7 and the mounting shell 8 to move laterally, thereby realizing the position adjustment of the hammer pressing component and adapting to the hammer pressing needs of different areas.

[0039] A power component 2 9 is fixedly connected to the side of the mounting shell 8. A disc 10 is eccentrically fixedly connected to the output end of the power component 2 9. A mating plate 11 is attached to the outer surface of the disc 10. Several sliding columns 12 are fixedly connected to the lower surface of the mating plate 11. The bottom end of the sliding column 12 slides through and extends out of the mounting shell 8 and is equipped with a hammer pressing component. The power component 2 9 drives the disc 10 to rotate. Through the mating cooperation between the disc 10 and the mating plate 11, the sliding column 12 is pushed to move up and down reciprocally, thereby driving the hammer pressing component to hammer the bract.

[0040] The hammer pressing component includes a main hammer head 13 fixedly connected to the bottom end of the sliding column 12 and a secondary hammer head 14 movably disposed inside the main hammer head 13. The combination design of the main hammer head 13 and the secondary hammer head 14 can be adapted to bracts of different sizes, avoiding impact damage to the seeds caused by a single hammer head.

[0041] The inner wall of the hammer pressing box 2 is hinged to two material plates 15 and two telescopic components 16. The telescopic end of the telescopic component 16 is hinged to the material plate 15 on the same side. The two material plates 15 form a temporary support surface for placing the bracts to be processed. The telescopic component 16 can adjust the tilt angle of the material plate 15 to control the falling speed of the material after hammer pressing.

[0042] The inner wall of the hammer pressing box 2 is fixedly connected to a feeding hopper 17, which guides the material to fall accurately into the washing box 18.

[0043] A washing tank 18 is placed on the surface of the base 1. The washing tank 18 is located directly below the hopper 17. The final separation of bracts and seeds is completed by washing with water, without the need for long-term soaking, which improves the separation efficiency and protects the seed activity.

[0044] In this embodiment, power component 5 and power component 9 are specifically selected as servo motors, and telescopic component 16 is specifically selected as a cylinder.

[0045] The mounting bracket 3 is installed on the hammer pressing box 2. The rotation of the threaded rod 6 drives the mounting shell 8 to reciprocate. The rotation of the disc 10 drives the hammer pressing component to reciprocate up and down. When used with the washing box 18, it realizes a combined working mode of hammer pressing pretreatment and water washing separation. The hammer pressing component shell quickly breaks the bract structure, realizing the initial separation of bracts and seeds. The subsequent water washing only needs a short time to complete the final separation, effectively improving the separation efficiency and avoiding the damage to seed activity caused by long-term soaking. By setting the main hammer head 13 and the auxiliary hammer head 14 movably set in the main hammer head 13, and with the elastic action of spring 1 23 and spring 2 25, the hammer pressure can be adaptively adjusted according to the bract characteristics to prevent the seeds from being damaged by the pressure and ensure good seed quality.

[0046] Several alignment rods 19 are fixedly connected to the surface of the hammer pressing box 2, and several alignment sleeves 20 for the alignment rods 19 to be inserted are fixedly connected to the side of the mounting frame 3. The cooperation between the alignment rods 19 and the alignment sleeves 20 can play a positioning and guiding role when the mounting frame 3 and the hammer pressing box 2 are assembled, ensuring that the mounting bolt holes 4 on the mounting frame 3 are precisely aligned with the corresponding holes on the hammer pressing box 2, avoiding assembly difficulties caused by hole offset during installation, and improving the structural stability after the mounting frame 3 and the hammer pressing box 2 are connected, reducing vibration displacement during hammer pressing operation.

[0047] The inner wall of the mounting bracket 3 is fixed with several guide rods 22, and the surface of the mounting shell 8 is fixedly connected with several guide sleeves 21 that are slidably sleeved on the outer surface of the guide rods 22. The sliding cooperation between the guide rods 22 and the guide sleeves 21 provides guidance for the lateral movement of the mounting shell 8, preventing the mounting shell 8 from twisting or shifting when the threaded rod 6 rotates, ensuring that the mounting shell 8 and the hammer pressing component always move smoothly along a straight line, improving the accuracy of the hammer pressing operation, and preventing uneven hammer pressing caused by the shaking of the mounting shell 8.

[0048] A spring 23 is fitted on the outer surface of the sliding column 12. The two ends of the spring 23 are fixedly connected to the surface of the mating plate 11 and the inner wall of the mounting shell 8, respectively. The spring 23 provides elastic restoring force for the mating plate 11. When the disc 10 rotates to the non-protruding position, the spring 23 can pull the mating plate 11 to quickly return to its original position, causing the sliding column 12 and the hammer pressing component to rebound upwards, realizing the reciprocating hammer pressing action of the hammer pressing component. The spring 23 can buffer the impact force of the disc 10 on the mating plate 11, reduce rigid collisions between components, and extend the service life of the equipment.

[0049] A second spring 25 and a telescopic rod 24 are fixedly connected to the inner wall of the main hammer head 13. Both the second spring 25 and the telescopic rod 24 are fixedly connected to the secondary hammer head 14. The second spring 25 and the telescopic rod 24 enable the secondary hammer head 14 to have an elastic buffering function. When the hammer pressing part contacts the bract, the secondary hammer head 14 can adaptively extend and retract according to the hardness and thickness of the bract, avoiding excessive pressure from the main hammer head 13 that directly damages the seeds. The telescopic rod 24 can limit the extension and retraction direction of the secondary hammer head 14, prevent the secondary hammer head 14 from deviating, and ensure that the hammer pressure is concentrated on the bract, thereby improving the bract breaking effect.

[0050] An arc-shaped slider 26 is fixedly connected to the side of the material plate 15. An arc-shaped groove is provided on the inner wall of the hammer pressing box 2 for the arc-shaped slider 26 to slide. The sliding cooperation between the arc-shaped slider 26 and the arc-shaped groove provides guidance for the hinged rotation of the material plate 15, ensuring that the material plate 15 rotates smoothly along a fixed trajectory under the drive of the telescopic member 16, and avoiding jamming or deviation when the material plate 15 rotates.

[0051] A limiting frame 27 is fixedly connected to the surface of the base 1. The washing tank 18 is inserted into the inner wall of the limiting frame 27. The limiting frame 27 is used to position and fix the washing tank 18 to prevent the washing tank 18 from shifting due to vibration during equipment operation. This ensures that the material falling from the hopper 17 falls accurately into the washing tank 18. The insert-type structure facilitates the placement and removal of the washing tank 18 and makes it convenient for subsequent collection and processing of the separated seeds and bracts.

[0052] When using

[0053] In the initial state, the two material plates 15 are in a horizontal closed state. At this time, the bracts of Quercus glauca to be separated are placed on the support surface formed by the two material plates 15 so that the bracts are evenly distributed.

[0054] Start the power component 5, which drives the threaded rod 6 to rotate. The movement of the threaded sleeve 7 causes the mounting shell 8 to move laterally along the guide rod 22. The forward and reverse rotation of the power component 5 drives the hammer pressing part to perform horizontal reciprocating motion.

[0055] Start the second power component 9, which drives the disc 10 to rotate. During the rotation of the disc 10, the mating plate 11 is pushed to move downward. The mating plate 11 drives the sliding column 12 and the hammer pressing component to move downward, hammering the bracts. When the disc 10 rotates to the non-protruding position, the first spring 23 pulls the mating plate 11 to reset, causing the hammer pressing component to spring back upward, realizing high-frequency reciprocating hammer pressing. The main hammer head 13 and the secondary hammer head 14 adaptively buffer under the action of the second spring 25 and the telescopic rod 24 to avoid damaging the seeds.

[0056] After the hammering is completed, the telescopic component 16 is controlled to retract, pushing the material plate 15 to rotate along the arc-shaped slide. The material plate 15 tilts so that the hammered material, namely the broken bracts and seeds, falls into the feed hopper 17.

[0057] The material is guided into the washing tank 18 through the feeding hopper 17. An appropriate amount of clean water is added to the washing tank 18. Due to its large weight, the seeds sink to the bottom of the tank, while the broken bracts float on the water surface. The final separation can be completed in a short time.

[0058] After separation, the washing box 18 is removed from the limiting frame 27 to collect the seeds and bracts separately;

[0059] Unscrew the bolts to unlock and remove mounting bracket 3.
