Description

Technical Field

[0001] This invention relates to the field of grassland restoration technology, and more specifically, to a grassland restoration method and apparatus based on grass seed pretreatment. Background Technology

[0002] The alpine grasslands of the Qinghai-Tibet Plateau are one of the world's most renowned grazing ecosystems. However, due to human activities and climate change, one-third of these grasslands have severely degraded, threatening the plateau's ecological environment.

[0003] Artificial reseeding is the main method for restoring severely degraded grasslands. However, the existing artificial reseeding methods are simple and cannot avoid the problems of drought and nutrient deficiency in the Qinghai-Tibet Plateau, nor can they solve the problem of irrigation after planting. This results in low seed germination rate, poor growth, and poor grassland restoration. At the same time, the existing grassland restoration task is heavy and the area to be restored is large. When the current artificial reseeding restoration method is applied to large areas of grassland, it is time-consuming, labor-intensive, expensive, and ineffective.

[0004] To address the aforementioned technical deficiencies, a grassland restoration method and apparatus based on grass seed pretreatment are proposed to solve the current problems. Summary of the Invention

[0005] The purpose of this invention is to provide a grassland restoration method and device based on grass seed pretreatment. It has a simple structure, is easy to use, has a long service life, can carry out batch restoration operations, and saves time and labor, greatly reducing grassland restoration and irrigation costs.

[0008] Furthermore, in this invention, the aforementioned pressure rod includes a top seat, on which a pneumatic telescopic rod is disposed; a pressure sensor is disposed between the pneumatic telescopic rod and the top seat.

[0009] Furthermore, in this invention, the bagging mechanism includes a conveyor belt, one end of which is provided with a knotting device; multiple fixing rings are provided on the conveyor belt, the radius of which is larger than the radius of the circular through groove; and a non-woven fabric sleeve is provided on the fixing ring.

[0010] Furthermore, in this invention, an electric telescopic rod is provided above the rotating disk, and a push plate is provided below the electric telescopic rod; the shape of the push plate is adapted to the shape of the circular through groove.

[0011] Furthermore, in this invention, a molding part is provided on the inner sidewall of the circular through groove, and the side of the molding part facing the center of the circular through groove is arc-shaped.

[0012] Furthermore, in this invention, the radius of the upper circular through groove is 3cm-10cm, and the length of the circular through groove is 0.5m-1.5m.

[0013] A grassland restoration method based on grass seed pretreatment, characterized by the following steps:

[0014] S1. Disinfect the grass seeds;

[0015] S2. Mix the nutrient soil and water-retaining agent, and then air-dry the mixture;

[0016] S3. Mix grass seeds with the mixed nutrient soil and water-retaining agent, and roll the mixture into strips;

[0017] S4. Soak the strip mixture in water for 2-3 hours;

[0018] S5. Dig trenches for the degraded grassland to be restored, then place the grass into the trenches and cover it with soil.

[0019] Furthermore, in this invention, in step S3 above, after the mixture is rolled into a strip, a non-woven fabric cover is applied to the outer casing.

[0020] Furthermore, in this invention, in step S3 above, a groove with the same length direction is provided on one side of the mixture; in step S5, the strip-shaped mixture is placed in the groove with the grooved side facing upward.

[0021] Furthermore, in this invention, step S5 above also includes a tape cutter, which includes a placement tube with an inclined bottom surface and an outlet on the lower side of the placement tube; a protrusion adapted to the shape of the groove is provided on the upper part of the placement tube, and a cutting blade is provided on the lower inner side of the outlet.

[0022] The present invention has at least the following advantages or beneficial effects:

[0023] Existing grass seed treatment methods are simple, but they cannot prevent the grass seeds from being easily blown away by strong winds due to their weight, nor can they effectively solve the problem of soil infertility in degraded grassland areas. Furthermore, existing grassland restoration methods, when applied to large areas of grassland, are time-consuming, labor-intensive, and expensive if irrigation is required, making them unsuitable for rapid restoration over large areas. This application provides a grass seed pretreatment device, including a base with a rotating disk on it. A filling and pressing mechanism is located above the rotating disk, and a bagging mechanism is located below the rotating disk. Multiple circular grooves are arranged in a ring on the rotating disk, and opening and closing doors are located at the bottom of the circular grooves. The filling and pressing mechanism includes a filling hopper, the lower part of which corresponds to the position of the circular grooves, and a pressing rod is located above the filling hopper. The radius of the pressing rod is smaller than the discharge port radius of the filling hopper and is adapted to the shape of the circular grooves.

[0024] This invention utilizes a circular channel to effectively form a long strip of grass seed and nutrient soil mixture. A pressure rod above the filling hopper compresses and compacts the mixture within the circular channel after filling, ensuring it is firmly packed into shape. This strip-shaped mixture allows workers to quickly sow and restore the grassland by digging trenches, pre-soaking the mixture in water to provide the necessary moisture and nutrients for seed germination and growth, and then directly placing it into the trenches. This method is time-saving, labor-saving, eliminates the need for irrigation, and ensures the grass seeds receive sufficient nutrition.

[0025] Meanwhile, by setting a shaping part in the circular through groove, the present invention can create a groove on one side of the strip mixture. The groove makes the shape of the strip mixture not cylindrical, which not only facilitates the stacking and transportation of the strip mixture, but also allows it to be placed in the groove.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0038] Example:

[0039] Please refer to Figure 1-8 This application provides a grass seed processing device, including a base 1, a rotating disk 2 on the base 1, a filling pressing mechanism above the rotating disk 2, and a bagging mechanism below the rotating disk 2; a plurality of circular through grooves 3 are arranged in a ring on the rotating disk 2, and an opening and closing door 4 is provided at the bottom of the circular through grooves 3; the filling pressing mechanism includes a filling hopper 5, the lower part of the filling hopper 5 corresponds to the position of the circular through groove 3, and a pressing rod 6 is provided above the filling hopper 5; the radius of the pressing rod 6 is smaller than the discharge port radius of the filling hopper 5 and is adapted to the shape of the circular through groove 3.

[0040] Existing methods for treating grass seeds are simple but cannot prevent the seeds from being easily blown away by strong winds, nor can they effectively address the problem of soil infertility in degraded grassland areas. Furthermore, existing grassland restoration methods are time-consuming and labor-intensive when applied to large areas, making rapid restoration difficult. This invention addresses this issue by using a circular channel 3, which allows the mixture of grass seeds and nutrient soil to form a long strip. A pressure rod 6 above the filling hopper 5 compresses and compacts the mixture within the circular channel 3 after filling, ensuring the mixture is firmly packed. The strip-shaped mixture allows workers to quickly sow and restore the grassland by digging trenches, pre-soaking the mixture in water to provide the necessary moisture and nutrients for seed germination and growth, and then directly placing it into the trenches. This saves time and labor, eliminates the need for irrigation, and ensures adequate nutrition for seed growth. The trenches also effectively contain the mixture, preventing movement or damage from strong winds. The opening door 4 allows workers to easily remove the mixture from the circular channel 3 from below.

[0041] Furthermore, in this invention, the aforementioned pressure rod 6 includes a top seat 7, on which a pneumatic telescopic rod 8 is mounted; a pressure sensor 9 is disposed between the pneumatic telescopic rod 8 and the top seat 7. The pressure sensor 9 disposed between the pneumatic telescopic rod 8 and the top seat 7 allows the operator to understand the pressure value of the pneumatic telescopic rod 8, thereby adjusting the compaction degree of the mixture; it is understood that the pneumatic telescopic rod 8 can be a commonly available telescopic rod structure; furthermore, a controller, such as a PLC controller, can be provided, allowing the operator to input the pressure value into the controller in advance, thereby adjusting the pressure of the pneumatic telescopic rod 8 based on the feedback from the pressure sensor 9 to ensure a consistent compaction degree of the mixture.

[0042] Furthermore, in this invention, the bagging mechanism includes a conveyor belt 10, one end of which is provided with a knotting device 11; a plurality of fixing rings 12 are provided on the conveyor belt 10, the radius of the fixing rings 12 being larger than the radius of the circular through groove 3; a polyethylene film sleeve 13 is provided on the fixing rings 12. The conveyor belt 10 is configured such that the fixing rings 12 on it can be moved sequentially to below the circular through groove 3, allowing the mixture to fall into the polyethylene film sleeve 13 provided on the fixing rings 12, and be knotted and sealed by the knotting device 11; the polyethylene film sleeve 13 is convenient for transportation and can effectively prevent moisture, making it easy to store; it is understood that the knotting device 11 can be a commonly available knotting device structure.

[0043] Furthermore, in this invention, an electric telescopic rod 14 is provided above the rotating disk 2, and a push plate 15 is provided below the electric telescopic rod 14; the shape of the push plate 15 is adapted to the shape of the circular through groove 3. The electric telescopic rod 14 and the push plate 15 are arranged so that the mixture in the circular through groove 3 can be pressed out; it is understood that the electric telescopic rod 14 can be a commonly available electric telescopic rod 14 structure; the electric telescopic rod 14 is positioned above the bagging mechanism.

[0044] Furthermore, in this invention, a shaping element 16 is provided on the inner sidewall of the circular channel 3, and the side of the shaping element 16 facing the center of the circular channel 3 is arc-shaped. By providing the shaping element 16 in the circular channel 3, this invention can create a groove on one side of the strip mixture. The groove prevents the strip mixture from being cylindrical, which not only facilitates the stacking and transportation of the strip mixture, but also allows for sufficient water absorption through irrigation by workers in the groove after it is placed in the groove.

[0045] Furthermore, in this invention, the radius of the upper circular channel 3 is 3cm-10cm, and the length of the circular channel 3 is 0.5m-1.5m, which facilitates the transportation and placement of the strip mixture and can effectively plant and restore grassland in a certain area.

[0046] In the actual work, the staff adds grass seeds and nutrient soil into the circular channel 3 through the filling hopper 5. It can be added at once or in multiple times, and then it is pressed tightly by the pressure rod 6. Then the rotating disc 2 rotates, and the filling hopper 5 can fill other circular channels 3. After filling, the circular channel 3 is rotated to the top of the bagging mechanism, and the mixture is pushed out from the circular channel 3 through the fixing ring 12 into the polyethylene film sleeve 13 and tied.

[0047] A grassland restoration method based on grass seed pretreatment, characterized by the following steps:

[0048] S1. Disinfect the grass seeds;

[0049] S2. Mix the nutrient soil and water-retaining agent, and then air-dry the mixture;

[0050] S3. Mix grass seeds with the mixed nutrient soil and water-retaining agent, and roll the mixture into strips;

[0051] S4. Soak the strip mixture in water for 2-3 hours;

[0052] S5. Dig trenches for the degraded grassland to be restored, then place the grass into the trenches and cover it with soil.

[0053] After disinfection treatment, the grass seeds are easier to store and develop. Air drying removes moisture, reduces weight, prevents premature germination, and extends storage time. The mixture is compressed into strips for easy placement into trenches. Specifically, in step S1, *Stipa purpurea*, *Leymus chinensis*, and barley grass seeds are mixed in a 4:4:2 mass ratio. In step S2, the mixed grass seeds, nutrient soil, and water-retaining agent are mixed in a 10:88:2 mass ratio. In step S3, the strip mixture is 50cm long and 5cm in diameter. In step S4, the trench is 10-20cm deep. This length of mixture facilitates storage and transportation and effectively ensures the germination rate and required nutrients for the grass seeds at this mixing ratio. Optionally, in step S4, after soaking the strip mixture in water for 2-3 hours, a hole (2mm in diameter) is made on one side using a pinhole, and then it is placed in the trench and buried, which can effectively accelerate the germination speed.

[0054] Furthermore, the grass seeds can be colored and mixed on one side of the mixture. When placing the mixture into the trench, workers can quickly determine which side has the most grass seeds by looking at the colored grass seeds. By placing the mixture with the grass seed-containing side facing up into the trench, it is easier for the seeds to germinate.

[0055] Furthermore, in this invention, in step S3 above, after the mixture is compressed into a strip, a non-woven fabric sleeve 13 is placed over it. In step S5 above, a groove with the same length direction as the mixture is provided on one side; in step S4, the strip-shaped mixture is placed in the groove with the grooved side facing upward, and the groove is irrigated by passing it through the non-woven fabric sleeve 13; the non-woven fabric sleeve 13 may be provided with several evenly distributed holes to facilitate air exchange and budding.

[0056] Furthermore, in this invention, step S5 above also includes a cutting device, which includes a placement tube 17 with an inclined bottom surface and an outlet on the lower side of the placement tube 17; a protrusion 18 adapted to the shape of the groove is provided on the upper part of the inside of the placement tube 17, and a cutting blade 19 is provided on the lower inner side of the outlet. A non-woven fabric sleeve 13 is fitted over the mixture and tightened to a certain extent. After the strip mixture passes through the cutting blade 19 of the placement tube 17, the non-woven fabric sleeve 13 is cut and, due to its own tightening, contracts from the bottom to both sides, allowing the lower part to contact the bottom of the trench for easy grass seed growth. It is understood that perforations are made in the non-woven fabric sleeve 13 on the upper side of the placed strip mixture to allow moisture to enter through the holes, while also providing good insulation and moisture retention, and effectively preventing wind damage.

[0057] In summary, embodiments of the present invention provide a grass seed processing device, including a base 1, a rotating disk 2 mounted on the base 1, a filling and pressing mechanism above the rotating disk 2, and a bagging mechanism below the rotating disk 2; a plurality of circular channels 3 are arranged in a ring on the rotating disk 2, and an opening and closing door 4 is provided at the bottom of the circular channels 3; the filling and pressing mechanism includes a filling hopper 5, the lower part of the filling hopper 5 corresponding to the position of the circular channels 3, and a pressing rod 6 above the filling hopper 5; the radius of the pressing rod 6 is smaller than the discharge port radius of the filling hopper 5 and is adapted to the shape of the circular channels 3. By setting the circular channels 3, the present invention allows the mixture of grass seeds and nutrient soil filled into them to effectively form an elongated shape. The pressing rod 6 above the filling hopper 5 can compress and compact the mixture within the circular channels 3 after filling, thus compacting the mixture into shape. The strip-shaped mixture allows workers to quickly sow and restore the grassland by digging trenches, pre-soaking the mixture in water to provide the necessary moisture and nutrients for seed germination, and then directly placing it into the trenches. This saves time and labor, eliminates the need for irrigation, and ensures the grass seeds receive adequate nutrition. Furthermore, the invention incorporates a shaping element 16 within the circular groove 3, creating a recess on one side of the strip-shaped mixture. This recess prevents the mixture from being cylindrical, facilitating stacking and transportation.

[0058] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
