Description

Technical Field

[0001] The present invention relates to the technical field of agricultural sowing, and in particular to a sowing belt for identifying disease resistance of wheat varieties, and a preparation device and process thereof. Background Art

[0002] Food security is crucial to my country's social stability and economic development, and is a matter of vital importance to people's livelihoods. It holds a unique position in China's agricultural production and development. Rice production accounts for nearly 40% of the country's total grain output and approximately 30% of the world's total. Food safety is closely linked to the occurrence of crop diseases. Breeding and utilizing disease-resistant varieties is the most economical, effective, and safest technology and measure in integrated crop disease prevention and control. It not only effectively controls diseases but also serves as a sustainable ecological protection measure. Crop disease resistance identification is essential for obtaining disease-resistant crop varieties. Currently, the selection, breeding, resistance identification, evaluation, and utilization of disease-resistant crop varieties have received high attention from government departments at all levels. my country's Ministry of Agriculture has also implemented a "veto system" for highly susceptible varieties to prevent the serious losses caused by the use of less resistant varieties in production.

[0003] During the sowing process of wheat, a certain distance needs to be left between the wheat to avoid the situation that the seeds or wheat seedlings are incomplete or stunted when they are small. In order to obtain the best seed sowing distance, the seeds are positioned by sowing belts in the prior art.

[0004] The sowing belt in the prior art is generally a double-layer structure, with seeds placed between the two paper layers at a constant distance from each other. However, the prior art still has the following problems:

[0005] 1. There are many wheat varieties undergoing disease resistance testing at the same time, which can easily lead to confusion when the wheat seeds are placed in the seed strips. After the wheat seeds germinate, it is impossible to accurately distinguish the growth of various wheat varieties, making it difficult to identify the disease resistance of each variety.

[0006] 2. During the seeding process, only one type of wheat seed can be seeded at a time. When identifying the disease resistance of wheat varieties, more wheat varieties are required, and seeding is time-consuming. In addition, a seeding device is generally used to suspend and drop wheat seeds in the air, which easily causes the wheat seeds to bounce and roll. Due to the effect of the adhesive, it is difficult to adjust the misplaced wheat seeds, resulting in inaccurate positioning of the wheat seeds, and the spacing between the wheat seeds cannot be arranged according to the expected array.

[0007] Therefore, it is necessary to provide a sowing belt, a preparation device and a process for identifying disease resistance of wheat varieties to solve the above technical problems. Summary of the Invention

[0020] The glue coating device is used to apply glue to the surface of the base tape, and the glue application location is the location other than the receiving portion and the germination unit;

[0021] The bonding device includes a plurality of ultrasonic bonding heads for bonding the bent base tape, and the bonding is divided into two steps;

[0022] The blowing device includes: a blower, a telescopic bracket, and a plurality of conduits provided at the lower portion of the telescopic bracket; the blower is connected to the conduits via an air pipe; the telescopic bracket is used to insert the guide rod into the germination unit through the receiving portion, and the blower blows air into the germination unit;

[0023] The seed-dispensing device comprises: a base, a column, a plurality of seeding discs, a plurality of seed flow channels and a driving device; the driving device is arranged on the lower side of the base, for driving the base to rotate slowly; a vortex groove is provided on the upper surface of the base, for placing the seeding belt, and the receiving portion faces upward; the column is arranged in the middle of the upper surface of the base, and a plurality of seeding discs are distributed in a linear array along the length direction of the column and on the outer surface of the column; a plurality of seed flow channels are equidistantly distributed on the circumferential surface of the seeding disc, the seed flow channels are inclined, and a plurality of equidistant steps are provided inside the seed flow channels, and the lowest steps in the plurality of seed flow channels are all in the same horizontal plane, and the lower end of each circle of the seed flow channels is arranged directly above the axis of each circle of the vortex groove;

[0024] The base of the seeding device rotates slowly with the sowing belt. During the rotation, when a number of the seed flow channels are located above the receiving portion, the wheat seeds are discharged from the seed flow channels and enter the receiving portion.

[0025] The shearing device is used to shear the receiving portion. The shearing timing is after the wheat seeds pass through the receiving portion and enter the germination unit. The shearing position is between the receiving portion and the germination unit.

When the seed flow channel reaches the top of the supporting part, the wheat seeds will fall through the supporting part into the germination unit. Then, glue the connecting position between the receiving part and the germination unit, and cut off the entire receiving part.

[0033] In a preferred embodiment of the present invention, in said S4, when the number of seed chambers in the lower seeding tray is insufficient to meet the sowing quantity of the wheat seeds of this variety, a sufficient number of seed chambers are selected in the upper seeding tray for sowing the wheat seeds of this variety, and the seeding bearing parts corresponding to the selected seed chambers are adjacent to the bearing parts corresponding to the lower seeding tray in the rotation direction.

[0034] The present invention solves the defects existing in the background technology and has the following beneficial effects:

[0035] (1) The present invention provides a sowing belt for identifying disease resistance of wheat varieties. The belt is provided with depressions arranged in an array on a base belt, a receiving portion is formed by combining the depressions, and a germination unit is formed below the receiving portion. The germination unit is filled by blowing, and multiple varieties of wheat seeds can be fixedly passed through the receiving portion and enter the germination unit to position the wheat seeds. This solves the problem of easy confusion of wheat seeds during sowing and the problem of bouncing and rolling of wheat seeds during sowing in the prior art.

[0036] (2) The present invention utilizes a receiving portion, a germination unit, and a seeding device to sow wheat seeds into the receiving portion at a fixed point. The wheat seeds enter the germination unit through the receiving portion, and the wheat seeds can be sent to the sowing belt at a fixed point and of a fixed variety. This solves the problem that there are many wheat varieties undergoing disease resistance identification at the same time, which easily leads to confusion during the process of sowing wheat seeds into the seed belt, and after the wheat seeds germinate, it is impossible to accurately distinguish the growth conditions of various wheat varieties, thereby improving the accuracy of wheat variety disease resistance identification.

[0037] (3) The present invention utilizes the vortex groove on the base to place the sowing belt, and multiple sowing trays store different varieties of wheat seeds, that is, each wheat seed corresponds to a circle of sowing belt in the vortex groove, so as to distinguish the varieties of wheat seeds, and by driving the base to rotate, when the seed flow channel is located above the bearing part, the seed flow channel is opened, and the wheat seeds are placed into the germination unit at a fixed point, thereby realizing the simultaneous sowing of multiple varieties of wheat, and the sowing is more uniform, saving time.

[0038] (4) The present invention is provided with a number of equidistant steps inside the seed flow channel, and each step from bottom to top is at the same horizontal plane. After the wheat seeds enter the seed flow channel from the seeding tray, they pause on each step, especially the lowest step, which are all at the same horizontal plane, so that the wheat seeds in different seeding trays are at the same height before seeding, and the time required for seeding is the same.

[0039] (5) The present invention utilizes the opening of the receiving part to actively receive the wheat seeds. The inner side of the receiving part is an opposing slope. When the wheat seeds enter the receiving part, they will slide to the bottom of the receiving part along the slope and be counted in the germination unit. There is no need for positioning, and the bouncing and rolling problems of the wheat seeds during the seeding process are reduced. It will not cause the precise positioning of the wheat seed belt final product, and solves the problem of difficulty in correcting and adjusting misplaced seeds during the seeding process in the prior art.

[0040] (6) The present invention utilizes a germination unit and glues the upper opening of the germination unit together to seal the wheat seeds in the germination unit. When the sowing belt is stored, the seeds will not fall out, and the wheat seeds can be positioned for easy use.

[0041] (7) The base tape of the present invention is prepared by melt-blown material through melt-blown technology. The melt-blown material is a polylactide material. On the one hand, it has a certain plasticity, which meets the requirements for the formation of depressions or germination units. On the other hand, after contacting soil or water, this material will decompose into carbon dioxide and water in one month, and under the action of sunlight photosynthesis, it will become the starting material of starch, which is pollution-free to the environment and has little effect on the germination of wheat seeds.

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated.

[0053] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0054] like Figure 1 and Figure 2 As shown, the present invention provides a sowing belt for identifying disease resistance of wheat varieties, including a base belt 1; the base belt 1 is long and strip-shaped, and the base belt 1 is bent and connected along the center line of the width direction. A plurality of recesses 2 are provided on the bent opening side of the base belt 1 and on both sides of the edge along the length direction. The plurality of recesses 2 are symmetrically arranged, and the symmetrical recesses 2 are connected to form a receiving portion 3. The inner bottom surface of the receiving portion 3 is set to a slope shape, and the receiving portion 3 is used to receive wheat seeds; a germination unit 4 is provided below the receiving portion 3, and the germination unit 4 is used to accommodate wheat seeds, and the germination unit 4 is connected to the receiving portion 3; the bent base belt 1 is bonded except for the receiving portion 3 and the germination unit 4; the plurality of recesses 2 are distributed in a linear array; the germination unit 4 is elliptical or oval.

[0055] It is worth noting that the base tape 1 is formed from a meltblown material using meltblowing technology. The meltblown material is a degradable material. In this embodiment, the preferred degradable material is polylactide. Polylactide is obtained by synthesizing lactic acid and polymerizing starch extracted from annual plants such as corn, wheat, and wood rose.

[0056] On the one hand, the polylactide material has a certain plasticity, which meets the requirements for the formation of the depression 2 or the germination unit 4. On the other hand, after contacting the soil or water, this material will decompose into carbon dioxide and water in one month, and under the photosynthesis of the sun, it will become the starting material of starch. It is pollution-free to the environment and has little effect on the germination of wheat seeds.

[0057] In this embodiment, the receiving portion 3 is terraced, triangular or elliptical, and the slopes are inclined downward from the two ends of the receiving portion 3 to the middle. A seed channel is provided between the opposite slopes at the two ends for wheat seeds to enter the germination unit 4 from the receiving portion 3.

[0058] In the present invention, the spacing between the depressions 2 on the base strip 1 is 8 to 11 cm, preferably 9 cm. The receiving portion 3 formed by combining the depressions 2 on the two long sides is terraced, triangular, elliptical, or other special-shaped structures. In this embodiment, the preferred receiving portion 3 is terraced. The receiving portion 3 is larger than the wheat seed, allowing the wheat seed to enter the receiving portion 3 smoothly and pass through the seed channel into the germination unit.

[0059] In this embodiment, the thickness of the base tape 1 at the locations of the depression 2 and the germination unit 4 is the largest.

[0060] The thickness of the base tape 1 at the locations of depression 2 and germination unit 4 is 1.5-1.8 mm, and the thickness at other locations is 1.0-1.3 mm. The base tape 1 at the locations of depression 2 and germination unit 4 is thickened to improve the plasticity of the base tape 1 and ensure the formation of depression 2 and germination unit 4. The internal space of germination unit 4 is larger than that of wheat seeds.

[0061] A plurality of communication holes are provided on the surface of the germination unit 4, which are used to connect the germination unit 4 with the outside world, so that the wheat seeds can exchange substances with the external soil or water, thereby improving the germination rate or emergence rate of the wheat seeds.

[0062] like Figure 3 As shown, the present invention also provides a preparation process for preparing a sowing tape for identifying disease resistance of wheat varieties as described above, comprising the following steps:

[0063] S1. A base tape 1 is formed by laminating using a meltblowing technique, and a plurality of depressions 2 are symmetrically formed on the two long edges of the surface of the base tape 1;

[0064] S2, bend the base tape 1 along the midline in the width direction, and form a receiving portion 3 by combining the depressions 2. Reserve a germination unit 4 below the receiving portion 3, and bond the bent base tape 1;

[0065] S3. Insert a catheter into the germination unit 4 from the upper side of the receiving portion 3 and blow air into the germination unit 4 through the catheter. After the germination unit 4 swells in all directions under the action of the air, remove the catheter.

[0066] S4. The distribution of different varieties of wheat seeds in the sowing tray 15 is divided according to the number of each wheat seed that needs to be planted. Wheat seeds of the same variety can only be stored in adjacent seed chambers. The sowing belt is placed in the vortex groove 17. By rotating the base 13, when the seed flow channel 16 reaches the top of the supporting part 3, the wheat seeds are scattered through the supporting part 3 and enter the germination unit 4. Then, the connecting position between the receiving part 3 and the germination unit 4 is glued, and the receiving part 3 is completely cut off.

[0067] Among them, when the number of seed chambers in the lower seeding tray 15 is insufficient to meet the sowing quantity of this variety of wheat seeds, a sufficient number of seed chambers are selected in the upper seeding tray 15 for sowing this variety of wheat seeds, and the seeding bearing part 3 corresponding to the selected seed chamber is adjacent to the bearing part 13 corresponding to the lower seeding tray 15 in the rotation direction.

[0068] It should be noted that the distribution of the seed chambers in each sowing tray 15, for example: the bottom sowing tray 15 has 4 seed chambers, which are equipped with No. 1 wheat seeds, but 5 No. 1 wheat seeds need to be sown, and the bottom sowing tray cannot meet its quantity requirements. The sowing tray 15 on the upper layer has 6 seed chambers, from which one seed chamber is separated to store No. 1 wheat seeds, and the remaining seed chambers store No. 2 wheat seeds. The bearing part 3 on the sowing belt corresponding to the seed flow channel 16 connected to the seed chamber for storing No. 1 wheat seeds is temporarily called bearing A, and the bearing part 3 on the sowing belt corresponding to the seed flow channel 16 connected to the bottom sowing tray 15 is temporarily called bearing B. Bearing A and bearing B are adjacent on their spiral line to ensure that the sowing positions of wheat seeds of the same variety are in one area.

[0069] The present invention also provides a preparation device for preparing the above-mentioned sowing belt for identifying disease resistance of wheat varieties, comprising: a forming device 5, a bending component 9, a gluing device, a bonding device, an air blowing device, a seed discharging device and a shearing device;

[0070] like Figure 4 As shown, the forming device 5 includes a plurality of meltblown heads 6 arranged in an array, and a conveyor belt 7 disposed directly below the plurality of meltblown heads 6; a plurality of conveyor protrusions 8 are disposed on both edges of the conveyor belt 7. The conveyor protrusions 8 in this embodiment are consistent in shape and size with the aforementioned depressions 2. The meltblown material is sprayed onto the surface of the conveyor belt 7 by the meltblown heads 6, and the meltblown material ejected by the meltblown heads 6 radiates the width of the conveyor belt 7. The number of meltblown layers of the base tape 1 is consistent with the number of meltblown head 6 arrays. The number of meltblown heads 6 located on one side of the conveyor protrusions 8 can be selectively adjusted to increase the thickness of the base tape 1 at the depressions 2 and the germination units 4.

[0071] like Figure 5As shown, the bending assembly 9 includes: a first clamping plate 10 and a second clamping plate 11 connected by a rotating shaft; the first clamping plate 10 and the second clamping plate 11 are provided with a plurality of bending grooves 12 on an edge away from the rotating shaft, and the bending grooves 12 are consistent in shape and size with the depressions 2 provided on the base belt 1, and their positions correspond one to one.

[0072] A clamp can be used to pull the base tape 1 and align it with the bending groove 12. The gluing device is used to apply glue to the surface of the base tape 1, and the glue application area is located outside the receiving portion 3 and the germination unit. The blowing device includes: a blower, a telescopic bracket, and a plurality of conduits disposed below the telescopic bracket; the blower is connected to the conduits via an air pipe; the telescopic bracket is used to insert the guide rod through the receiving portion 3 and into the germination unit 4, and the blower blows air into the germination unit 4;

[0073] The bonding device includes several ultrasonic bonding heads, which are used to bond the bent base tape 1. The bonding is divided into two times: the timing and position of the two bonding are different. The first bonding time is after the long strip structure is bent, and the bonding position is outside the receiving part 3 and the germination unit 4; the second bonding time is after the wheat seeds pass through the receiving part 3 and enter the germination unit 4, and before cutting the receiving part 3, and the bonding position is the connection part between the receiving part 3 and the germination unit 4.

[0074] like Figure 6 As shown, the seeding device includes: a base 13, a column 14, a plurality of seeding discs 15, a plurality of seed flow channels 16 and a driving device; the driving device is arranged on the lower side of the base 13, for driving the column 14 to rotate slowly; a vortex groove 17 is provided on the upper surface of the base 13 for placing the seeding belt, and the receiving portion 3 is facing upward, and the position space of the vortex groove 17 corresponding to the germination unit 4 is larger than that of the other parts; the column 14 is arranged in the middle of the upper surface of the base 13, and a plurality of seeding discs 15 are distributed in a linear array along the length direction of the column 14 and on the outer surface of the column 14; a plurality of seed flow channels 16 are equidistantly distributed on the circumferential surface of the seeding disc 15, the seed flow channels 16 are inclined, and a plurality of equidistant steps are provided inside the seed flow channels 16, and the lowest steps in the plurality of seed flow channels 16 are all in the same horizontal plane, and the lower end of each circle of seed flow channels 16 is arranged directly above the axis of each circle of the vortex groove 17.

[0075] The base 13 of the seeding device rotates slowly with the sowing belt. During the rotation, when the seed flow channels 16 are located above the receiving portion 3, the wheat seeds are discharged from the seed flow channels 16 and enter the receiving portion 13.

[0076] The number of seeding plates 15 is equal to the number of circles of the vortex groove 17. The seed flow channel 16 on the lowest seeding plate 15 is used to discharge seeds to the seeding belt of the innermost circle of the vortex groove 17... The seed flow channel 16 on the uppermost seeding plate 15 is used to discharge seeds to the seeding belt of the outermost circle of the vortex groove 17; a plurality of seed chambers are arranged in the seeding plate 15, and the plurality of seed chambers are equally divided, and each seed chamber is correspondingly provided with a seed flow channel 16.

[0077] It should be noted that the innermost circle of the vortex groove 17 is larger in diameter than the bottom seeding disc 15. A scoreline can be set on the inner wall of the vortex groove 17 corresponding to the center line of the germination unit 4. When placing the seeding belt, the germination unit 4 is aligned with the scoreline. Because the spacing of the receiving parts 3 is constant, the number of receiving parts 3 present in each circle of the seeding belt in the vortex groove 17 is also constant. The number of seed flow channels 16 set on the seeding disc 15 is set according to the number of receiving parts 3. The number of seed flow channels 16 in the inner circle is less than that in the outer circle. When the base 13 rotates slowly with the seeding belt, an image sensor or a touch switch can be used to open the seed flow channel 16 every time the outlet end of the seed flow channel 16 rotates above the receiving part 3, allowing the wheat seeds to fall from the seed flow channel 16 into the receiving part 3. In this way, after one slow rotation, a seeding belt can be fully loaded with wheat seeds, realizing the simultaneous sowing of multiple varieties of wheat, and the sowing is more uniform, saving time. The device can avoid confusion of wheat seeds during seeding, is stable and can reduce the spillage of wheat seeds.

[0078] The seed flow channel 16 is provided with several steps along its cross section. The presence of the steps allows the wheat seeds to be distributed on each step after being discharged from the seeding tray 15, especially the lowest steps are all on the same horizontal plane, so that the wheat seeds in different seeding trays 15 are at the same height before seeding, and the time required for seeding is the same.

[0079] Different layers of sowing trays 15 correspond to different circles of sowing belts, and can hold different varieties of wheat seeds. After the wheat seeds fall into the receiving parts 3 on the inner circle of the sowing belt, the outer circle of seeds are sown. This takes up less space, and the directional sowing can reduce the waste of wheat seeds.

[0080] The shearing device is used to shear the receiving part 3 . The shearing time is after the wheat seeds pass through the receiving part 3 and enter the germination unit 4 . The shearing position is between the receiving part 3 and the germination unit 4 .

[0081] It should be noted that the adhesive used in this embodiment is glutinous rice glue, whose main ingredients are edible glutinous rice starch, edible potassium sorbate, edible white vinegar, and water. The glutinous rice glue in this embodiment is edible-grade glue, eliminating concerns about wheat seed safety and environmental pollution. In this embodiment, the glutinous rice glue does not come into direct contact with the wheat seeds; it only serves to shape the depressions 2 and germination units 4 and seal the germination units 4, preventing any impact on the wheat seeds.

[0082] This embodiment also provides a method for using the preparation device, comprising the following steps:

[0083] B1. Forming of the base belt 1: The meltblown head 6 sprays the meltblown material onto a conveyor belt 7 having conveyor protrusions 8 on both edges in the longitudinal direction. The meltblown material sprayed by the meltblown head 6 just radiates the width of the conveyor belt 7 to form the base belt 1;

[0084] B2. Clamp traction alignment: Clamp the base belt 1 with a clamp, pull it and align it to the middle position between the first clamping plate 10 and the second clamping plate 11, and ensure that the depression 2 on the base belt 1 corresponds to the bending groove 12 one by one;

[0085] B3. Positioning and Gluing: Glue is applied to the surface of the base tape 1 using a glue applying device.
