Description

Technical Field

[0001] The utility model relates to the technical field of seed pre-treatment, in particular to a contact-type seed treatment device based on ultrasonic enhanced activity. Background Art

[0002] Ultrasound is a sound wave with a frequency higher than the sound frequency range that the human ear can hear. Specifically, the frequency of ultrasound is usually above 20 kilohertz (Khz) and up to several gigahertz (Ghz). When this high-frequency sound wave propagates in the medium, it can produce a series of unique physical and chemical reactions. Therefore, it is widely used in many fields, such as medical diagnosis, industrial testing, cleaning, welding, and seed treatment in agriculture.

[0003] Ultrasonic treatment of seeds is mainly achieved through cavitation. When ultrasound propagates in liquid (water inside the seed), its sound pressure changes cause the particles in the liquid to quickly switch between dense and sparse states, forming cavities. These cavities will undergo a process of growth, oscillation and final collapse under the continuous action of ultrasound, which is the cavitation phenomenon. The cavitation effect of ultrasound can, on the one hand, activate the enzyme system in the seeds, increase the activity of the enzyme, and help accelerate the biochemical reaction in the seeds. On the other hand, it promotes the diffusion and mixing of substances inside the seeds, making it easier for macromolecules such as starch and protein in the seeds to be decomposed into small molecules, such as glucose and amino acids. These small molecules are more easily absorbed and utilized by the seed embryo, thereby accelerating the germination and growth of the seeds. In addition, the cavitation effect of ultrasound can destroy the physiological structure of seed dormancy, such as the hardened layer of the seed coat or endosperm, making it easier for the seeds to swell and start the germination process.

[0004] Since ultrasound can effectively improve the activity of seeds after seed treatment, it has significant significance for seed germination and growth. In order to promote agricultural productivity, this application proposes a contact seed treatment device based on ultrasound enhanced activity, which has a simple and lightweight structure and can meet the needs of large-scale ultrasonic seed treatment. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The contact seed treatment device based on ultrasonic enhanced activity comprises a hopper and a matching layer, wherein the matching layer is arranged obliquely below the hopper, and a drop opening is arranged at the lower part of the hopper to guide the seeds to fall onto the matching layer.

[0008] The hopper comprises an inclined guide side wall to guide the seeds to fall onto the matching layer through the drop opening, and the inclination direction of the guide side wall is the same as or opposite to the inclination direction of the matching layer.

[0010] The hopper further comprises a limiting side wall, the limiting side wall is located on the opposite side of the guiding side wall, and the limiting side wall and the guiding side wall define the material drop opening on the limiting side wall.

[0011] The hopper is provided with an adjusting mechanism to adjust the opening size of the material drop opening.

[0012] An inclination angle of the guide sidewall is greater than an inclination angle of the matching layer.

[0013] The inclination angle of the matching layer is not greater than 20°.

[0014] A plurality of adjusting parts are arranged on the guide side wall, and the adjusting parts are arranged evenly and in parallel along the inclined direction of the guide side wall.

[0015] The contact seed treatment device based on ultrasonic enhanced activity also includes a frame, the matching layer is rotatably arranged on the frame, and a flexible pad is arranged at the connection between the matching layer and the frame.

[0016] A first guide is provided at the drop opening to guide the seeds dropped from the drop opening to the matching layer.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model provides a contact seed treatment device based on ultrasonic enhanced activity, please refer to Figure 1-Figure 2 , including a hopper 1 and a matching layer 2, the matching layer 2 is obliquely arranged below the hopper 1, and a drop opening 10 is arranged at the lower part of the hopper 1 to guide the seeds to fall onto the matching layer 2.

[0030] In the present application, seeds are poured into a hopper 1, and the seeds fall onto the matching layer 2 through a drop port 10 under the action of gravity. The matching layer 2 emits ultrasonic waves, so that the seeds are stimulated by the ultrasonic waves generated by the matching layer 2 during their movement on the inclined matching layer 2. At the same time, since the seeds are in direct contact with the matching layer 2 during the stimulation process, the matching layer 2 can fully and effectively process the seeds in a short time, so as to achieve the purpose of enhancing the activity of the seeds.

[0031] Through the above structure, under the premise of achieving ultrasonic treatment of seeds, a simple and lightweight structure is constructed to realize a seed treatment device that can quickly and continuously process large quantities of seeds. The hopper 1 and the matching layer 2 are arranged up and down to form a three-dimensional structure, so that the entire device has a compact structure and a small size, which is convenient for operators to carry to farmlands or experimental sites for seed treatment.

[0032] For further information, see Figure 1-Figure 5 The hopper 1 includes an inclined guide side wall 11 to guide the seeds to fall onto the matching layer 2 through the drop opening 10 . The inclination direction of the guide side wall 11 is the same as or opposite to the inclination direction of the matching layer 2 .

[0033] The inclined guide side wall 11 in the present application, on the one hand, helps to utilize the effect of gravity to make the seeds slide down naturally in the hopper 1, reduce the residue of seeds on the guide side wall 11, thereby improving the fluidity and uniformity of the seeds and reducing the risk of seed blockage and accumulation in the hopper 1; on the other hand, it reduces the impact of the seeds on the matching layer 2 after falling through the drop port 10, so that the seeds are spread on the matching layer 2 as evenly as possible, ensuring the effectiveness of the ultrasonic treatment.

[0034] For further information, see Figure 1-Figure 6 The hopper 1 further includes at least one limiting side wall 12 , and the guiding side wall 11 and the limiting side wall 12 define a material drop opening 10 at the lower part of the hopper 1 .

[0035] In the present application, the guiding side wall 11 cooperates with different numbers of limiting side walls 12 to define a discharge port 10 at different positions of the lower part of the hopper 1. The number of limiting side walls 12 can be one, two, three, four, etc. (it should be noted that the number of limiting side walls 12 refers to: the number of limiting side walls 12 that cooperate with the guiding side walls 11 to define the discharge port 10, rather than the number of hopper side walls 100 that cooperate with the guiding side walls 11 to form the hopper 1. Of course, the limiting side walls 12 may also serve as hopper side walls and cooperate with the guiding side walls 11 to form a hopper).

[0036] In one embodiment of the present application, when the number of limiting side walls 12 is one, the limiting side wall 12 is located on the opposite side of the guiding side wall 11. Since the guiding side wall 11 is inclined, the lower end of the guiding side wall 11 will intersect with the lower end of the limiting side wall 12. At this time, the material drop at the boundary between the limiting side wall 12 and the guiding side wall 11 is located on the surface where the limiting side wall 12 or the guiding side wall 11 is located (that is, a material drop opening 10 is provided on the limiting side wall 12 or the guiding side wall 11), and the opening width of the material drop opening 10 is smaller than the smaller one of the limiting side wall 12 and the guiding side wall 11; in order to improve the uniformity of seeds falling from the material drop opening 10 to the matching layer 2, in this embodiment, the opening of the material drop opening 10 is in the shape of a long strip; at the same time, in this embodiment, the limiting side wall 12, the guiding side wall 11 and the two hopper side walls 100 cooperate to form the hopper 1, that is, the limiting side wall 12 also serves as one of the side walls of the hopper 1.

[0037] In another embodiment of the present application, when the number of limiting side walls 12 is two, the two limiting side walls 12 serve as the hopper side walls 100 and cooperate with the inclined guiding side walls 11 to form the hopper 1. At this time, the drop port 10 is located at the lower end of the hopper 1, and the opening shape of the drop port 10 is a triangle.

[0038] In another embodiment of the present application, when the number of limiting side walls 12 is three, the three limiting side walls 12 serve as the hopper side walls 100 and cooperate with the guiding side walls 11 to form the hopper 1, one limiting side wall 12 is located on the opposite side of the guiding side wall 11, and the other two limiting side walls 12 are relatively arranged to connect the guiding side wall 11 and the limiting side walls 12 on the opposite side of the guiding side wall 11. At this time, the drop port 10 can be located at the lower end surface of the hopper 1; preferably, the opening of the drop port 10 is in the shape of a long strip.

[0039] In another embodiment of the present application, when the number of limiting side walls 12 is four, the four limiting side walls 12 are combined as the hopper side walls 100 to form the hopper 1, and at least one of the limiting side walls 12 is inclined, and the lower end of an inclined limiting side wall 12 is connected to the upper end of the guiding side wall 11, and the inclination angle rate of the inclined limiting side wall 12 is greater than the inclination angle of the guiding side wall 11. The purpose of the above-mentioned setting is that after the seeds are poured into the hopper 1 along the inclined limiting side walls 12, the guiding side walls 11 can provide a certain buffer for the seeds to prevent the seeds from directly impacting the matching layer 2 through the drop port 10. In this embodiment, the opening direction of the drop port 10 is set along the inclination direction of the guiding side wall 11.

[0040] In an optional embodiment, the present application takes the structure of the seed processing device as an example in which the hopper 1 includes a limiting side wall 12, the limiting side wall 12 is located on the opposite side of the guiding side wall 11, the limiting side wall 12 and the guiding side wall 11 define a drop opening 10 on the surface where the limiting side wall 12 is located, and the width of the drop opening 10 is smaller than the width of the limiting side wall 12. An adjustment mechanism 13 is provided on the hopper 1 to adjust the opening size of the drop opening 10.

[0041] In the present application, after the seeds are poured into the hopper 1 and slide down along the guide side wall 11, the inclined guide side wall 11 allows the seeds to fall through the drop port 10 onto the matching layer 2 under the action of gravity. In order to enable the seed treatment device to adapt to the ultrasonic treatment of different types of seeds (such as rice, peanuts, beans, corn, wheat, cotton seeds, etc.), an adjustment mechanism 13 is provided on the hopper 1, and the size of the drop port 10 can be adjusted according to different types of seeds; at the same time, the flow rate of the seeds falling through the drop port 10 to the matching layer 2 can be controlled by controlling the opening size of the drop port 10, so as to control the uniformity of the seeds falling onto the matching layer 2; the falling flow rate of the seeds is adjusted to a degree that matches the ultrasonic frequency and power generated by the matching layer 2, so as to avoid the occurrence of situations such as the ultrasonic treatment time of the seeds being too short or too long, the accumulation or stacking of some seeds and the inability to receive sufficient ultrasonic stimulation, and prevent the ultrasonic treatment effect from failing to meet expectations.

[0042] Furthermore, the purpose of setting the material opening 10 on the limiting side wall 12 rather than at the lower end of the hopper 1 is to achieve a visual effect in the process of adjusting the opening size of the material opening 10. When the operator adjusts the opening size of the material opening 10, it is more intuitive to visually view the side where the limiting side wall 12 is located compared to visually viewing the bottom surface of the hopper 1, which is conducive to the operator timely and accurately adjusting the opening size of the material opening 10. In the present application, the adjustment mechanism 13 can be set on the limiting side wall 12 to adjust the opening size of the material opening 10.

[0043] Furthermore, the adjustment mechanism 13 includes an adjustment plate 131 and an adjustment member 132 for controlling the position of the adjustment plate 131. The adjustment plate 131 is driven to move by the adjustment member 132 to adjust the opening size of the drop port 10. Compared with the drop port 10 with a fixed opening size, the opening size of the drop port 10 is adjustable. On the one hand, during the actual use of the device, it is convenient for the operator to control the opening size of the drop port 10 according to actual conditions, thereby improving the uniformity of seeds falling through the drop port 10. On the other hand, the drop port 10 can adapt to different types of seeds (that is, the opening size of the drop port 10 can be adjusted according to the size of the seeds), thereby enhancing the versatility of the hopper 1. The setting of the adjustment plate 131 can be set according to the position of the blanking opening 10; when the hopper 1 includes a limiting side wall 12, the limiting side wall 12 is located on the opposite side of the guiding side wall 11, and the limiting side wall 12 and the guiding side wall 11 define the blanking opening 10 on the limiting side wall 12. For example, in this embodiment, the adjustment plate 131 can be set on the limiting side wall 12, and a waist-shaped hole is provided on the adjustment plate 131, and a threaded hole is provided on the limiting side wall 12. The adjustment member 132 can be a knob screw, and the height of the adjustment plate 131 can be controlled along the limiting side wall 12. The knob screw passes through the waist-shaped hole and the threaded hole to adjust the height of the adjustment plate 131. The adjustment plate 131 is fixed at different heights of the limiting side wall 12, so as to adjust the opening size of the blanking port 10. At the same time, in order to ensure that the adjustment plate 131 is easy to adjust along the limiting side wall 12, a guide plate 121 is provided on the outer side of the limiting side wall 12. There are two guide plates 121. There is a gap between the guide plate 121 and the limiting side wall 12 for the adjustment plate 131 to slide along the outer side of the limiting side wall 12, which greatly facilitates the operator to control the height of the adjustment plate 131 after loosening the knob screw; of course, the adjustment member 132 can also use a linear module unit to achieve automatic adjustment. It should be noted that the purpose of setting the adjustment mechanism 13 is to adjust the opening size of the blanking port 10. Therefore, the specific setting position of the adjustment mechanism 13 can be adjusted according to the opening direction and position adaptability of the blanking port 10.

[0044] For further information, see Figure 2-Figure 6 A vibrator 14 is provided on the hopper 1; the vibrator 14 can be provided on the guide side wall 11 or the limiting side wall 12. When the seeds fall, the vibrator 14 is turned on to make the hopper 1 vibrate, which is beneficial to improve the uniformity of the seeds falling from the drop port 10 to the matching layer 2 and to avoid the seeds from being blocked at the drop port 10 as much as possible.

[0045] Furthermore, the main surface of the guide side wall 11 is a plane, and a plurality of adjusting parts 15 are provided on the guide side wall 11. The adjusting parts 15 are evenly and parallelly arranged along the inclination direction of the guide side wall 11. The adjusting parts 15 may be arc-shaped recessed grooves or arc-shaped protrusions. The spacing between two adjacent adjusting parts 15 is greater than the width of a single adjusting part 15. The adjusting parts 15 are slightly raised or recessed in the plane where the guide side wall 11 is located, and they only play a role of segmented buffering, and will not cause local or overall large-scale accumulation of seeds; the purpose of setting the adjusting parts 15 on the guide side wall 11 is that the vibrator 14 transmits vibration to the hopper 1 when working, and the setting of the adjusting parts 15 plays a role of segmented buffering for the seeds in the process of the seeds moving along the guide side wall 11 to the drop port 10, and adjusts the uniformity of the seeds during the movement process, thereby helping the seeds to be spread as flatly as possible on the matching layer 2 after falling from the drop port 10, which is beneficial to improving the effect of the matching layer 2 in processing seeds. When the number of the limiting side walls 12 is four, the inclined limiting side wall 12 is a plane, and the adjusting portion 15 can also be arranged on the inclined limiting side wall 12. At this time, the seeds after multiple buffering are further buffered by the guiding side wall 11, further ensuring the uniformity of the seeds falling from the drop opening 10 to the matching layer 2. Of course, in order to achieve a better effect of ultrasonic treatment of the seeds on the matching layer 2, the adjusting portion 15 can also be arranged on the matching layer 2.

[0046] Furthermore, a first guide member 3 is provided at the drop port 10 to guide the seeds falling from the drop port 10 to the matching layer 2. The movement direction of the seeds is changed by the first guide member 3, so that the seeds move toward the position of the matching layer 2 after hitting the first guide member 3, so as to avoid the seeds from failing to accurately fall onto the matching layer 2 along the opening direction of the drop port 10 under the action of inertia, thereby ensuring that the seeds accurately and stably fall onto the matching layer 2. In the embodiment of the present application, the first guide member 3 is provided on the frame 4 and is an integrally formed plate-like structure. The first guide member 3 includes a first inclined surface 3 1. A second inclined surface 32 connected to one end of the first inclined surface 31 and a third inclined surface 33 connected to the other end of the inclined surface. The first inclined surface 31 faces the side of the drop port 10 and is bent at 90° with the second inclined surface 32. The second inclined surface 32 and the third inclined surface 33 are bent at 90°, and the inclination angle of the second inclined surface 32 is not less than the inclination angle of the matching layer 2. The third inclined surface 33 is approximately perpendicular to the matching layer 2. After the seeds pass through the drop port 10, they collide with the second inclined surface 32 and can fall smoothly onto the matching layer 2 under the guidance of the first inclined surface 31 and the third inclined surface 33. Of course, it is foreseeable that in order to smoothly guide the seeds from the drop port 10 to the matching layer 2, the first guide member 3 can also be set as a curved surface so that the seeds slide along the first guide member 3 to the matching layer 2. At the same time, the first guide member 3 can also be set as a hollow cube with openings at the upper and lower ends to guide the seeds from the drop port 10 to the matching layer 2.

[0047] Further, the matching layer 2 includes a plate body 21 and an ultrasonic source 22 welded to the bottom of the plate body 21. The plate body 21 is an ultrasonic vibration plate, and the ultrasonic source 22 is an ultrasonic generator. In the present application, the frequency of the ultrasonic wave generated by the ultrasonic source 22 is 20khz-50khz, the power is 1000w-2600w, and the ultrasonic wave treatment time ranges from 10s to 600s for the seed; the shape of the matching layer 2 is square or rectangular, and the size range of the matching layer 2 is 400mm-800mm, that is, the smallest matching layer 2 is 400mm*400mm, and the largest matching layer 2 is 800mm*800mm; preferably, the plate body 21 is a plane and the shape of the plate body 21 is a square, which is conducive to the uniform transmission of ultrasonic waves and ensures the effect of ultrasonic treatment of seeds; the ultrasonic source 22, the seed treatment time and the size of the matching layer 2 can be selected according to different seeds, and the present application does not make specific restrictions here. In the present application, the plate body 21 can be made of metal material, which is convenient for welding, especially stainless steel plate, which can avoid rusting of the matching layer 2 during ultrasonic treatment due to immersion treatment of some seeds before ultrasonic treatment. Welding between the plate body 21 and the ultrasonic source 22 can achieve organic fusion of the ultrasonic source 22 and the plate body 21, so that the vibration source formed by the entire matching layer 2 during operation can generate waves for a long time without generating heat, avoiding the accumulation of more heat in the plate body 21 with better heat transfer effect after long-term continuous ultrasonic treatment of seeds, thereby causing protein deformation and inactivation of seeds. Of course, it also avoids the adhesion of some seeds soaked in medicine on the steel plate due to heat, resulting in reduced quality of the finished product.

[0048] In the present application, the ultrasonic source 22 and the plate 21 are two different objects before coupling, and a new ultrasonic source 22 (i.e., the matching layer 2 in the present application) is formed after coupling. When the ultrasonic wave generated by the ultrasonic source 22 passes through the plate 21, the two will be coupled. This coupling will cause the waveform, frequency, and energy distribution of the ultrasonic wave to change when it propagates on the plate 21, and then the wave will appear in the plate 21 in the form of longitudinal waves, transverse waves, and clutter. If the adapted power generator 45 and the coupled new ultrasonic source 22 have different frequencies, the propagation of the ultrasonic wave in the plate 21 will become disordered, which will lead to The waves collide with each other, resulting in a large amount of energy loss. The energy generated by the collision is mainly manifested in the form of heat energy. If the heat cannot be dissipated, it will affect the working performance and service life of the matching layer 2. The ultrasonic sources 22 of different frequencies will form a new resonant frequency after coupling with the plate 21. The resonant frequency can be detected by an impedance analysis instrument. According to the detected resonant frequency, the corresponding power generator 45 is adapted and finally adjusted to the optimal parameters to achieve complete resonance. This is conducive to reducing the heat generated during the ultrasonic propagation process, while reducing energy loss and improving the effect of seed ultrasonic treatment.

[0049] Further, the inclination angle of the guide side wall 11 is greater than the inclination angle of the matching layer 2 , and the inclination angle of the matching layer 2 is not greater than 20°.

[0050] In the present application, since the seeds fall onto the matching layer 2 through the drop port 10 under the guidance of the guide side wall 11, the inclination angle of the guide side wall 11 is greater than the inclination angle of the matching layer 2, so that the flow rate of the seeds on the guide side wall 11 is greater than the flow rate on the matching layer 2, which can ensure the continuity of the seeds falling onto the matching layer 2 through the drop port 10, which is beneficial to improving the seed processing efficiency; further, the inclination angle of the guide side wall 11 is 30°-75°, and the inclination angle of the guide side wall 11 helps to utilize the effect of gravity to make the seeds slide naturally in the hopper 1, reduce the residence time of the seeds in the hopper 1, and improve the seed processing efficiency. At the same time, a larger inclination angle can ensure that the seeds are not easily accumulated or blocked at the drop port 10 when sliding up and down the guide side wall 11, thereby ensuring the fluidity and uniformity of the seeds; further, in order to avoid the inclination angle of the guiding side wall 11 being too large, which may cause the seeds falling through the drop port 10 to the matching layer 2 to roll or slide under the impact, thereby reducing the contact time with the matching layer 2; preferably, the inclination angle of the guiding side wall 11 is 60°, which ensures that the seeds are guided smoothly to the drop port 10 while avoiding the angle being too large to cause the seeds to impact the matching layer 2.

[0051] In the present application, the inclination angle of the matching layer 2 affects the seed treatment effect. If the inclination angle of the matching layer 2 is too large, the seed flow rate will be too fast. The too fast flow rate will cause insufficient ultrasonic treatment time for the seeds, thereby affecting the effect of the ultrasonic treatment; if the inclination angle of the matching layer 2 is too small, the seeds will pile up due to the slow flow rate, the treatment time of the lower layer seeds will be too long, and the upper layer seeds will not receive sufficient ultrasonic treatment, which will lead to uneven seed treatment effect. Therefore, the matching layer 2 with an inclination angle not exceeding 20° can better guarantee the seed treatment effect and can also be applied to most seeds.

[0052] Furthermore, the inclination angle of the matching layer 2 can be set to 1-5°. Since different seeds have different shapes, such as spherical or flat beans, corn, etc., the flow rates of seeds of different shapes and sizes on the matching layer 2 are different, and the surface friction coefficients of different seeds are also different. Therefore, the inclination angle of the matching layer 2 will have a greater impact on the ultrasonic treatment time of the seeds. If the entire device only uses one matching layer 2 to ultrasonically treat the seeds, the inclination angle of 1°-5° can adapt to most seeds and make the seeds have a more suitable flow rate. The matching layer 2 has a good ultrasonic treatment effect for seeds of various shapes such as flat and spherical. Of course, those skilled in the art can also use a matching layer 2 with a larger angle according to actual needs, and set multiple matching layers 2, and the inclination directions of multiple matching layers 2 can be the same or opposite. It is also a feasible way to let the seeds flow slightly sparsely through the surface of the matching layer 2 while ensuring that the seeds have sufficient treatment time.

[0053] Furthermore, the contact seed treatment device based on ultrasonic enhanced activity also includes a frame 4, the matching layer 2 is rotatably arranged on the frame 4, and a flexible pad 41 is arranged at the connection between the matching layer 2 and the frame 4.

[0054] In the embodiment of the present application, the hopper 1 and the matching layer 2 are both arranged on the frame 4, and the side of the matching layer 2 close to the drop opening 10 is inclined upward, that is, the inclination direction of the guiding side wall 11 is opposite to the inclination direction of the matching layer 2. The seeds fall to the higher side of the matching layer 2 through the drop opening 10 under the guidance of the guiding side wall 11, ensuring that the processing time of the seeds on the matching layer 2 will not be too short. At the same time, the arrangement of the above structure makes the assembly of the seed processing device more compact and more three-dimensional, reducing the occupied area of ​​the processing device; in addition, casters 40 are arranged at the bottom of the frame 4 to facilitate the movement of the entire processing device, realizing a truly small, lightweight and movable ultrasonic processing device, which is very convenient for operators to use in actual production labor. The side of the plate body 21 of the matching layer 2 is connected to the frame 4 through a flexible pad 41. The arrangement of the flexible pad 41 prevents the vibration generated by the vibrator 14 from being transmitted to the matching layer 2 through the frame 4 to affect the processing effect of the seeds, and improves the stability of the matching layer 2 in processing seeds. The plate body 21 of the matching layer 2 is disposed on the frame 4 via a rotating shaft, and the rotating shaft drives the plate body 21 to rotate. The inclination angle of the plate body 21 can be adjusted to meet the requirements of ultrasonic treatment of different seeds.

[0055] The contact seed treatment device based on ultrasonic enhanced activity also includes a receiving bin 42 and an ultraviolet lamp (not shown in the figure). The receiving bin 42 is arranged below the matching layer 2 along the inclined direction of the matching layer 2 to receive the seeds after the ultrasonic treatment. The ultraviolet lamp is arranged at the bottom of the frame 4 or the hopper 1 to irradiate the seeds on the matching layer 2. After the seeds are ultrasonically treated, they can directly fall into the receiving bin 42 along the setting direction of the plate body 21. The operator can directly take the receiving bin 42 out of the frame 4, which is convenient for the operator to carry out subsequent treatment; the ultraviolet lamp is turned on during the ultrasonic treatment of the seeds, so that the seeds are subjected to ultrasonic treatment and ultraviolet irradiation at the same time, which can further improve the germination rate and yield of the seeds.

[0056] Furthermore, a second guide member 5 is provided at the end of the matching layer 2. The second guide member 5 is located above the receiving bin 42. The second guide member 5 is a hollow cubic structure with openings at both ends. On the one hand, it prevents the seeds from flying around due to collision and impact with the second guide member 5 due to inertia after leaving the matching layer 2. On the other hand, the seeds that have been ultrasonically treated can smoothly enter the receiving bin 42 under the guidance of the second guide member 5 after leaving the matching layer 2, which is convenient for the operator to collect the completed seeds.

[0058] As an optional implementation scheme of the utility model, the power of the ultrasonic source 22 can be controlled by the function button 46 according to the seed type, and the vibrator 14 can be started by the start-stop button 46 when unloading. Among them, the circuit design between the control panel 44 and the power generator 45, the matching layer 2, and the vibrator 14 meets the requirement of no heat during long-term operation. Of course, those skilled in the art can also use a cooling fan or other methods to reduce the temperature inside the rack 4; when the seeds are irradiated by the ultraviolet lamp, the ultrasonic source 22 can be turned on synchronously or not, and the specific choice depends on the seed type.

[0059] The frame 4 is also provided with a plurality of cabinet doors 48. As an optional implementation scheme of the present invention, the cabinet doors 48 are especially designed at the position of the baffle plate, and when the opening size of the blanking opening 10 needs to be adjusted, the cabinet doors 48 can be directly opened to adjust.
