Description

Technical Field

[0001] The present invention relates to the technical field of electron beam irradiation, and specifically to a device and method for accelerating the ripening of forest tree seeds by means of electron accelerator ray irradiation. Background Art

[0002] At present, most of the forest tree seeds are treated by chemical methods in the market to accelerate the ripening of seeds. For chemical agent germination acceleration, for example, putting the seeds of sumac and certain legumes in concentrated sulfuric acid solution for short-term soaking can make the sumac seed coat soft and thin, so that it can permeate water and air. During the soaking process, continuous stirring is required, and after soaking, it is also necessary to rinse with clean water. The whole process requires manual operation, which is time-consuming and laborious. Using an electron accelerator to generate a certain amount of electron beams to irradiate forest tree seeds can stimulate germination, plant growth and the synthesis of photosynthetic pigments. However, in the existing seed irradiation technology, a certain amount of seeds need to be placed manually for irradiation, and the staff is at risk of being irradiated, and the ripening efficiency is low. Summary of the Invention

[0003] The purpose of the present invention is to provide a device and method for accelerating the ripening of forest tree seeds by means of electron accelerator ray irradiation, so as to solve the problems raised in the above background art.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: A device for accelerating the ripening of forest tree seeds by means of electron accelerator ray irradiation includes a transportation mechanism, an irradiation mechanism and a delivery box. The transportation mechanism is responsible for transporting the delivery box to the irradiation mechanism. A blanking mechanism is also installed on one side of the transportation mechanism, and the blanking mechanism is responsible for providing forest tree seeds for the delivery box. The irradiation mechanism is responsible for irradiating and accelerating the ripening of the forest tree seeds in the delivery box. The transportation mechanism is used to transport empty delivery boxes. During the transportation process, a certain amount of forest tree seeds can also be poured into the empty delivery boxes through the blanking mechanism. Then, the delivery boxes filled with forest tree seeds are sent to the irradiation mechanism, and the irradiation mechanism irradiates and accelerates the ripening of the forest tree seeds.

[0005] The irradiation mechanism includes an irradiation table and an irradiation conveyor. An electron accelerator is installed inside the irradiation table. The irradiation conveyor passes through the irradiation table, and the electron accelerator is located above the irradiation conveyor. The type of the electron accelerator is an electron curtain accelerator. The delivery box filled with forest tree seeds is transported to the irradiation table through the irradiation conveyor, and the electron curtain accelerator in the irradiation table generates electron beams to irradiate and accelerate the ripening of the forest tree seeds. The electron curtain accelerator is a self-shielded accelerator, with a small volume, regular appearance and simple structure, and does not occupy too much space on the production line.

[0006] The irradiation conveyor includes a frame, a drive shaft, and an irradiation conveyor belt. The drive shaft is installed in the middle of the frame, the irradiation conveyor belt is installed on the drive shaft, the drive shaft meshes with the irradiation conveyor belt for transmission, and a conveyor box baffle is installed above the frame. The drive shaft drives the irradiation conveyor belt to rotate to transport the conveyor box. The conveyor box baffle is installed on both sides of the frame, leaving a space in the middle for the conveyor box to pass through, ensuring that the conveyor box is in the middle position of the irradiation conveyor belt, which is convenient for the electron accelerator to irradiate.

[0007] The irradiation conveyor is also equipped with a vibration mechanism. The vibration mechanism is located inside the irradiation conveyor belt. The vibration mechanism includes a vibration base, a vibration plate, a vibration spring, a rotating rod, and a rotating shaft. The vibration base is installed in the middle of the frame, the vibration plate is located above the vibration base, the vibration spring is installed between the vibration base and the vibration plate, the rotating shaft is installed on the vibration base, the vibration base has an opening, a part of the rotating rod passes through the opening, the rotating rod can rotate within the opening, one end of the rotating rod is rotatably connected to the rotating shaft, and the other end of the rotating rod is connected to the vibration plate. When the conveyor box passes above the vibration mechanism, it is vibrated, so that the forest tree seeds in the conveyor box are evenly distributed in the conveyor box, which is convenient for the electron accelerator to irradiate each seed evenly.

[0008] The number of drive shafts is four. One of the drive shafts is connected to a motor. The rotating shaft and one of the drive shafts are driven by a belt. The irradiation conveyor belt is a plate conveyor belt. The installation position of the vibration mechanism is in front of the irradiation table. The motor provides power for the drive shaft to rotate and drive the irradiation conveyor belt to move. The rotating shaft of the vibration mechanism is driven by a belt with the drive shaft, and uses the rotation of the drive shaft to vibrate, making more efficient use of the power. The vibration mechanism is installed in front of the irradiation table. When the conveyor box enters the irradiation table, the seeds in the conveyor box are evenly distributed in the box without accumulation, improving the ripening efficiency.

[0009] The transportation mechanism includes a conveying table, a blanking mechanism, a conveyor box conveyor, and a transfer table. The blanking mechanism is installed on the top of the conveying table, the conveyor box conveyor is installed on one side of the conveying table, and the transfer table is installed between the conveyor box conveyor and the conveying table. The conveyor box conveyor transports the empty conveyor box to the conveying table. A transfer table is installed between the conveyor box conveyor and the conveying table to fill the gap between the conveyor box conveyor and the conveying table, facilitating the entry of the conveyor box from the conveyor box conveyor into the conveying table. After entering the conveying table, the blanking mechanism fills the empty conveyor box with forest tree seeds and then sends it to the irradiation mechanism.

[0010] The conveying table is equipped with a lifter and a pusher. The lifter is installed inside the conveying table, and the pusher is installed on the top of the conveying table. The lifter is equipped with a pressure sensor, and a lifting baffle is installed at the edge of the lifter. The blanking mechanism is located above the pusher. The conveying box enters the lifter from the conveying box conveyor. The pressure sensor of the lifter senses the weight of the conveying box and starts to rise. The lifting baffle also rises to prevent the subsequent conveying boxes from entering the lifter. After rising to the top of the conveying table, the blanking mechanism fills the conveying box with forest tree seeds. When the pressure sensor senses a certain weight, the pusher then pushes the conveying box into the irradiation mechanism.

[0011] The blanking mechanism includes a hopper and a blanking pipe. The blanking pipe is installed at the bottom of the hopper, and the installation angle of the blanking pipe is inclined. An electromagnetic throttle valve is installed inside the blanking pipe, and a vibration motor is installed at the bottom of the side of the hopper. The inclined installation of the blanking pipe facilitates the sliding of forest tree seeds into the conveying box. The vibration motor installed at the bottom of the side of the hopper provides a certain vibration to prevent the forest tree seeds from piling up, facilitating blanking. An electromagnetic throttle valve is installed inside the blanking pipe. After the pressure sensor on the lifter monitors a certain weight of seeds, the electromagnetic throttle valve closes, and the blanking ends, ensuring that the number of forest tree seeds in each conveying box is approximately the same.

[0012] A method for accelerating the ripening of forest tree seeds by irradiating with electron accelerator rays uses a device for accelerating the ripening of forest tree seeds by irradiating with electron accelerator rays. The method includes the following steps:

[0013] S1. Place the seeds in a conveying box;

[0014] S2. The conveying box is vibrated, and the seeds in the conveying box are evenly distributed in the conveying box;

[0015] S3. Irradiate the surface of the seeds from top to bottom with an electron beam.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. Traditional methods for accelerating seed ripening use chemical methods such as soaking seeds. The steps are cumbersome, the ripening time is long, and it is troublesome to collect the seeds after ripening. The present invention accelerates the ripening of forest tree seeds based on an electron accelerator. The process is convenient and fast. By irradiating with an electron beam, slight DNA damage is caused, which stimulates the DNA repair mechanism of the seeds, thereby promoting cell division and the growth of the seeds, achieving the effect of ripening.

[0018] 2. The lifter and pusher in the transportation mechanism ensure that the transportation boxes enter the irradiation mechanism in sequence. The feeding mechanism ensures that the weight of the forest tree seeds loaded in each transportation box is similar. The vibration mechanism in the irradiation mechanism provides vibration, enabling the seeds accumulated in the transportation box to be evenly spread out in the box after passing through the vibration mechanism, facilitating irradiation by the electron accelerator. The entire device has a high degree of automation, automatically transports the transportation boxes, automatically loads the seeds, and automatically transports the transportation boxes filled with seeds to the irradiation table for irradiation, reducing labor intensity.

[0034] The irradiation mechanism includes an irradiation table 1 and an irradiation conveyor. An electron accelerator is installed inside the irradiation table 1.

The irradiation conveyor belt 20 is installed on the drive shaft 19. The drive shaft 19 is in meshing transmission with the irradiation conveyor belt 20. A delivery box baffle 3 is installed above the frame 2.

[0036] The irradiation conveyor is also equipped with a vibration mechanism. The vibration mechanism is located inside the irradiation conveyor belt 20 and includes a vibration base 10, a vibration plate 11, vibration springs 12, a rotating rod 13, and a rotating shaft 14. The vibration base 10 is installed in the middle of the frame 2. The vibration plate 11 is located above the vibration base 10.

[0037] There are four driving shafts 19. One of the driving shafts 19 is connected to a motor 21. The rotating shaft 14 and one of the driving shafts 19 are driven by a belt. The irradiation conveyor belt 20 is a plate conveyor belt. The installation position of the vibration mechanism is in front of the irradiation table 1.

[0038] A method for accelerating the ripening of forest tree seeds by electron accelerator ray irradiation uses a device for accelerating the ripening of forest tree seeds by electron accelerator ray irradiation. The method includes the following steps:

[0039] S1: Place the seeds in a delivery box.

[0040] S2: The delivery box is vibrated, and the seeds in the delivery box are evenly distributed within the delivery box.

[0041] S3: Irradiate the surface of the seeds from top to bottom with an electron beam.

[0042] The working principle of the present invention: Pour the forest tree seeds to be ripened into the hopper 6. A vibration motor 17 is installed at the bottom of the side of the hopper 6 to ensure that there is no blockage during feeding. The delivery box conveyor 5 continuously transports the empty delivery boxes 9 to the delivery table 4. The delivery box 9 enters the elevator 15 inside the delivery table 4 through the transfer table 18 from the delivery box conveyor 5. The pressure sensor inside the elevator 15 monitors the weight of the delivery box 9, and the elevator 15 starts to lift the delivery box 9. The lifting baffle 16 connected to the edge of the elevator 15 also starts to rise, preventing the subsequent delivery boxes 9 from entering the elevator 15. After the delivery box 9 rises to the top of the delivery table 4, the electromagnetic throttle valve in the feeding pipe 7 opens, and the forest tree seeds enter the delivery box 9 from the hopper 6. When the pressure sensor monitors a certain weight again, the electromagnetic throttle valve closes and the feeding stops. The pusher 8 pushes the delivery box 9 filled with forest tree seeds onto the irradiation conveyor belt 20. When the pressure sensor no longer detects gravity, the elevator 15 starts to descend, and the subsequent delivery boxes 9 can enter the elevator 15.

[0043] The motor 21 provides power to the drive shaft 19. The drive shaft 19 rotates, and the rotation of the drive shaft 19 drives the irradiation conveyor belt 20 to rotate. The drive shaft 19 and the rotating shaft 14 are in belt drive. The rotating shaft 14 rotates, and the rotation of the rotating shaft 14 drives the rotating rod 13 to rotate. The other end of the rotating rod 13 drives the vibrating plate 11 to move up and down, generating vibration. The up and down movement of the vibrating plate 11 drives the upper irradiation conveyor belt 20 to vibrate.

[0044] After the delivery box 9 containing forest tree seeds is pushed onto the irradiation conveyor belt 20, the delivery box 9 is transported in the middle of the irradiation conveyor belt 20 along the delivery box baffle 3. When the delivery box 9 passes through the vibration mechanism, it is vibrated. The accumulated forest tree seeds in the delivery box 9 are vibrated and evenly spread out in the delivery box 9. After the delivery box 9 passes through the vibration mechanism, it is then transported by the irradiation conveyor belt 20 into the irradiation table 1. The electron curtain accelerator generates an electron beam, which irradiates the surface of the forest tree seeds from top to bottom. Then the delivery box 9 is transported out of the irradiation table 1, and the ripening is completed.
