Description

Technical Field

[0001] The invention relates to the technical field of Elymus salsa cultivation, and in particular to a cultivation system and method for improving the seed yield of Elymus salsa. Background Art

[0002] Elymus dahliae is a short-lived perennial forage grass with a wide range of adaptability. It can grow in areas with an annual average temperature of 3℃-16℃, a frost-free period of 100-280 days, and an annual precipitation of 150-600 mm. It is not only drought-resistant and cold-resistant, but also has many advantages such as resistance to trampling and poor soil. It is one of the excellent soil and water conservation plants. At the same time, Elymus dahliae has high yield and excellent nutritional value, and is a good forage for herbivorous livestock.

[0003] However, the seeds of Elymus salsa are light and have poor soil penetration ability, so fine land preparation is required to ensure sowing quality and uniform emergence of seedlings. Deep plowing should be carried out in autumn when sowing for the first time, with a plowing depth of about 20-30 cm. In addition, sufficient base fertilizer (such as organic manure) should be applied during land preparation, with 1000-1200 kg per mu as base fertilizer.

[0004] In the existing Elymus salsa cultivation system, the depth of seeds sown into the soil by the furrow opener in the seeding unit is uneven, and when the Elymus salsa seeds are sown into the soil, the compactor compacts the seeds too tightly, which will cause the seedlings to be of different heights after emerging from the soil and have different growth rates, thus affecting the yield of Elymus salsa.

[0005] Therefore, how to solve the problem in the existing Elymus salsa planting and cultivation system that the furrow opener in the sowing unit sows the seeds into the soil at an uneven depth and the compactor compacts the Elymus salsa seeds too tightly when the seeds are sown into the soil, resulting in the seedlings emerging from the soil with different heights and growth rates, thereby affecting the yield of Elymus salsa has become a difficult problem that needs to be urgently solved in this field. To this end, it is necessary to propose a cultivation system and method for increasing the seed yield of Elymus salsa. Summary of the invention

[0006] To solve the above problems, the present invention provides a cultivation system and method for increasing the seed yield of Elymus genus, which can intelligently adjust the sowing parameters of Elymus genus according to the environment, improve the soil-breaking ability of Elymus genus, and thus increase the seed yield of Elymus genus.

[0007] In order to achieve the above object, the technical solution of the present invention is as follows: A cultivation system for increasing the yield of Elymus seeds, comprising:

[0008] Transmission module, used to provide power for the cultivation system.

[0009] The walking module comprises a vehicle body and a plurality of driving wheels, wherein the driving wheels are rotatably matched with the outer side wall of the vehicle body; the driving wheels are used for driving the vehicle body to move in the cultivation area.

[0010] The seed separation module is used for screening out large-grained Elymus dahuricus seeds and small-grained Elymus dahuricus seeds, sowing the large-grained Elymus dahuricus seeds and storing the small-grained Elymus dahuricus seeds.

[0011] The furrow opening module is used to open a sowing furrow in the soil and plant large-grained Elymus seeds in the sowing furrow.

[0012] The soil covering module is used for covering the large-grained Elymus salsa seeds with soil after the large-grained Elymus salsa seeds are sown.

[0013] The control module includes a controller, and the controller is used to control the seed separation module and the soil covering module.

[0014] The technical principles of the above scheme are as follows:

[0015] The transmission module provides power for the entire cultivation system; the trenching module can open equal-depth sowing trenches in the soil as the vehicle body moves forward; the seed separation module screens large-grained Elymus salsa seeds and small-grained Elymus salsa seeds, and uses the power provided by the transmission module to sow the large-grained Elymus salsa seeds into the sowing trench; the soil covering module, under the control of the control module, can cover the large-grained Elymus salsa seeds sown in the sowing trench with soil of different intensities as the vehicle body moves forward.

[0016] The above scheme has the following beneficial effects:

[0017] 1. The present invention screens large and small Elymus salsa seeds through a seed sorting module and preferentially sows large seeds. Since large seeds usually have stronger vitality and soil-breaking ability, this helps to improve the emergence rate and growth rate of Elymus salsa, thereby increasing yield.

[0018] 2. The control module in the present invention can intelligently adjust the operating force of the soil covering module to ensure that the large-grained Elymus salsa seeds are appropriately covered, and their growth will not be inhibited due to over-tight compaction, nor will they be exposed to the external environment due to insufficient soil coverage. This helps to maintain soil moisture and temperature and provide suitable growth conditions for the seeds.

[0019] 3. The present invention realizes fully automated operations from seed screening, sowing to soil covering through an integrated system design, including a transmission module, a walking module, a seed sorting module, a furrowing module and a soil covering module, thereby improving cultivation efficiency, reducing manual intervention, and reducing production costs. At the same time, it also helps to improve the yield and quality of Elymus salsa seeds.

[0020] Furthermore, the transmission module includes a transmission unit, which includes a first sprocket wheel and a rotary tillage frame. The rotary tillage frame is fixedly connected to the bottom front end of the vehicle body in the movement direction. A roller is provided in the rotary tillage frame. One end of the roller passes through the side wall of the rotary tillage frame and is coaxially fixedly connected to the first sprocket wheel. The other end of the roller rotates with the inner wall of the rotary tillage frame. A number of rotary tillage teeth are fixedly connected to the side wall of the roller. A drive box is fixedly connected to the top of the vehicle body, and a first driving member is fixedly connected to the bottom wall of the drive box. The output shaft of the first driving member passes through the side wall of the drive box and is coaxially fixedly connected to the second sprocket wheel. A first chain is sleeved between the first sprocket wheel and the second sprocket wheel.

[0021] Beneficial effects: Through the design of the rotary tillage frame and rotary tillage teeth, the soil can be effectively broken and loosened when the vehicle body moves forward, creating better soil conditions for subsequent sowing and covering operations, improving the soil's air permeability and water retention capacity, and facilitating the growth of Elymus salsa seeds.

[0022] Furthermore, the seed sorting module includes a seed screening unit, which includes a sowing box and a seed storage box. The bottoms of the sowing box and the seed storage box are fixedly connected to the top of the vehicle body, and the tops of the sowing box and the seed storage box are both opened; a second driving member is fixedly connected to the top of the seed storage box, and the output shaft of the second driving member is coaxially fixedly connected to the rotating shaft, and a screen frame is fixedly connected to the side wall of the rotating shaft, and the screen frame is located above the opening of the seed storage box; a screen is detachably connected to the bottom of the screen frame; a controller is used to control the operation of the second driving member; a plurality of bucket grooves are fixedly connected to the bottom of the vehicle body, and the bucket grooves are all connected to the sowing box, and the bottoms of the bucket grooves are all fixedly connected to a sowing tube; an axle is provided at the bottom of the vehicle body, and one end of the wheel axle is coaxially fixedly connected to a third sprocket, and a second chain is sleeved between the third sprocket and the second sprocket, and the other end of the wheel axle passes through the side wall of the bucket groove and rotates with the side wall of the bucket groove; a dial wheel is coaxially fixedly connected to the wheel axle located in the bucket groove, and a plurality of U-shaped holes are opened on the dial wheel.

[0023] Beneficial effects: The seed screening unit can accurately screen out large and small Elymus salsa seeds, ensuring that only large and vigorous seeds are used for sowing, thus improving the utilization rate and germination rate of seeds. At the same time, the detachable design of the screen facilitates the replacement of screens with different apertures, allowing users to screen out Elymus salsa seeds of different particle sizes for sowing according to actual conditions.

[0024] Furthermore, the furrowing module includes a furrowing unit, and the furrowing unit includes a plurality of plowing covers, and the plowing covers are all fixedly connected to the outer side wall of the lower part of the sowing tube.

[0025] Beneficial effects: The design of the plow cover can ensure that a uniform and deep sowing furrow is formed during sowing, which is conducive to the uniform distribution of seeds and the development of the root system. At the same time, the plow cover can also prevent soil from entering the sowing tube during the forward movement of the vehicle body.

[0026] Furthermore, the soil covering module comprises a soil covering unit, and the soil covering unit comprises a bracket, and the bracket is hinged on the rear end side wall in the moving direction of the vehicle body; and a soil covering wheel is rotatably matched on the bracket.

[0027] Beneficial effect: The bracket is hinged on the rear end side wall in the direction of movement of the vehicle body, so that as the vehicle body moves forward, the covering wheel can evenly cover the sown seeds due to its own weight when rolling over the large-grained alkali grass seeds sown in the sowing furrow, ensuring that the seeds are covered with an appropriate amount of soil. The seeds will not be inhibited from growing due to over-tight compaction, nor will they be exposed to the external environment due to insufficient soil coverage.

[0028] Furthermore, a pressure sensor is fixedly connected to the bottom wall of the seeding box, and the controller is used to receive a pressure signal sent by the pressure sensor, and based on the pressure signal, control the output shafts of the first driving member and the second driving member to stop rotating and thereby stop the seeding operation of the cultivation system.

[0029] Beneficial effect: The design of the pressure sensor can monitor the number of seeds in the seeding box in real time. When the number of seeds is insufficient, the controller controls the first driving member and the second driving member to stop running, thereby avoiding uneven sowing or missed sowing due to insufficient seeds.

[0030] Furthermore, a plurality of grooves are formed on the covering wheel along its circumference.

[0031] Beneficial effects: The groove design can increase the contact area between the covering wheel and the soil, improving the covering effect. At the same time, the groove can also play a role in breaking up the soil, making the soil more fine and uniform, which is conducive to the growth and germination of seeds.

[0032] Furthermore, an electric push rod is fixedly connected to the bottom of the rear end in the direction of movement of the vehicle body, and the output shaft of the electric push rod is hinged to the bottom of the bracket; the controller is used to control the telescopic distance of the electric push rod and thus adjust the position of the bracket.

[0033] Beneficial effect: The design of the electric push rod can adjust the height and angle of the covering wheel by extending and retracting the output shaft according to the actual environmental conditions, so as to control the pressure of the covering wheel on the alkali grass seeds and avoid excessive pressure affecting the soil-breaking ability of the alkali grass seeds.

[0034] Furthermore, it also includes a monitoring module, which includes a monitoring unit, and the monitoring unit includes a temperature and humidity sensor, which is fixedly connected to the top of the vehicle body; the controller is used to receive the temperature and humidity signals sent by the temperature and humidity sensor, and control the operation of the electric push rod based on the temperature and humidity signals.

[0035] Beneficial effects: The design of the temperature and humidity sensor can monitor the temperature and humidity changes in the cultivation area in real time, and provide accurate monitoring data for the controller. The controller can intelligently adjust the operation of the electric push rod according to the real-time monitored temperature and humidity signals, ensuring that the soil covering operation is carried out under suitable temperature and humidity conditions, which is conducive to improving the germination rate and growth rate of seeds.

[0036] Further, a cultivation method for increasing the yield of Elymus spp. seeds is based on the operation of the above-mentioned cultivation system for increasing the yield of Elymus spp. seeds, and comprises the following steps:

[0037] Step 1, adding seeds: adding Elymus dactylis seeds into the screen frame in the seed screening unit.

[0038] Step 2, soil tillage: Use the driving wheels of the walking module to move the vehicle body to the alkali grass planting area, and the control module controls the transmission to drive the roller and rotary tillage teeth in the rotary tillage frame to rotate to till the soil.

[0039] Step three, seed screening and sowing: the control module controls the seed screening unit to sow the large-grained Elymus salsa seeds and store the small-grained Elymus salsa seeds.

[0040] Step 4: soil monitoring and soil covering force adjustment: the monitoring unit monitors the temperature and humidity signals of the environment in real time. The control module controls the soil covering wheels in the soil covering module to move up and down to change the soil covering force according to the temperature and humidity signals of the environment. When the vehicle body moves forward, the soil covering wheels cover the sown large-grained alkali grass seeds with soil.

[0041] Beneficial effects: Through a fine screening process, the present invention can accurately distinguish between large and small seeds of Elymus salsa seeds, and give priority to sowing large seeds with stronger vitality, which not only improves the utilization rate and germination rate of seeds, but also reduces seed waste through precise sowing control, thereby improving the overall sowing accuracy and efficiency; the temperature and humidity changes in the cultivation area are monitored in real time by a temperature and humidity sensor, and the operation of the electric push rod is intelligently regulated according to these changes, thereby adjusting the height and angle of the covering wheel, and realizing precise control of the pressure of the covering of the Elymus salsa seeds; it avoids affecting the ability of the seeds to break the soil due to excessive pressure, and also ensures that the seeds are covered with an appropriate amount of soil, providing a good soil environment for the growth of the seeds.

[0053] The walking module comprises a vehicle body 1 and a plurality of driving wheels 2. The driving wheels 2 are all rotatably matched with the outer side wall of the vehicle body 1. The driving wheels 2 are used to drive the vehicle body 1 to move in the cultivation area.

[0054] The seed separation module is used for screening out large-grained Elymus dahuri seeds and small-grained Elymus dahuri seeds, sowing the large-grained Elymus dahuri seeds and storing the small-grained Elymus dahuri seeds.

[0055] The seed sorting module includes a seed screening unit, which includes a seeding box 10 and a seed storage box 11. The bottoms of the seeding box 10 and the seed storage box 11 are fixedly connected to the top of the vehicle body 1 by bolts, and the tops of the seeding box 10 and the seed storage box 11 are both opened; the top of the seed storage box 11 is fixedly connected to a second driving member 12 by bolts, and the output shaft of the second driving member 12 is coaxially fixedly connected to a rotating shaft 13 by bolts, and a screen frame 14 is fixedly welded on the side wall of the rotating shaft 13, and the screen frame 14 is located above the opening of the seed storage box 11, and a screen is detachably connected to the bottom of the screen frame 14; the controller is used to control the operation of the second driving member 12 A plurality of bucket grooves 15 are fixedly connected to the bottom of the vehicle body 1 by bolts, and the bucket grooves 15 are communicated with the seeding box 10, and the bottom of the bucket grooves 15 are fixedly welded and communicated with the seeding tube 16; a wheel axle 17 is provided at the bottom of the vehicle body 1, and a third sprocket wheel 18 is coaxially fixedly connected to one end of the wheel axle 17 by bolts, and a second chain 19 is sleeved between the third sprocket wheel 18 and the second sprocket wheel 8, and the other end of the wheel axle 17 passes through the side wall of the bucket groove 15 and rotates with the side wall of the bucket groove 15; a paddle wheel 20 is coaxially and integrally formed on the wheel axle 17 located in the bucket groove 15, and a plurality of U-shaped holes 21 are opened on the side wall of the paddle wheel 20.

[0056] A pressure sensor is fixedly connected to the inner bottom wall of the seeding box 10 by screws. The controller is used to receive the pressure signal sent by the pressure sensor, and based on the pressure signal, controls the output shafts of the first driving member and the second driving member 12 to stop rotating and thus stop the seeding operation of the cultivation system.

[0057] The furrow opening module is used to open a sowing furrow in the soil and plant large-grained Elymus seeds in the sowing furrow.

[0058] The furrowing module includes a furrowing unit, and the furrowing unit includes a plurality of plowing covers 22 . The plowing covers 22 are all fixedly welded to the lower outer side wall of the sowing tube 16 .

[0059] The soil covering module is used for covering the large-grained Elymus salsa seeds with soil after the large-grained Elymus salsa seeds are sown.

[0060] The soil covering module comprises a soil covering unit, which comprises a bracket 23 hinged to the rear end side wall of the vehicle body 1 in the moving direction; a soil covering wheel 24 is rotatably matched on the bracket 23, and a plurality of grooves 25 are formed on the soil covering wheel 24 along its circumference.

[0061] The rear end bottom of the vehicle body 1 in the moving direction is fixedly connected with an electric push rod 26 by bolts, and the output shaft of the electric push rod 26 is hinged to the bottom of the bracket 23; the controller is used to control the telescopic distance of the electric push rod 26 and thus adjust the position of the bracket 23.

[0062] The control module includes a controller, and the controller is used to control the seed separation module and the soil covering module.

[0063] The monitoring module includes a monitoring unit, which includes a temperature and humidity sensor, which is fixedly connected to the top of the vehicle body 1 by screws; the controller is used to receive the temperature and humidity signals sent by the temperature and humidity sensor, and control the operation of the electric push rod 26 based on the temperature and humidity signals.

[0064] The cultivation method for increasing the yield of Elymus spp. seeds is based on the operation of the cultivation system for increasing the yield of Elymus spp. seeds, and comprises the following steps:

[0065] Step 1, adding seeds: adding Elymus dahliae seeds into the screen frame 14 in the seed screening unit.

[0066] Step 2, tilling the soil: using the driving wheel 2 of the walking module to move the vehicle body 1 to the lycopene planting area, the control module controls the transmission to drive the roller 5 and the rotary tillage teeth 6 in the rotary tillage frame 4 to rotate, and the soil is tilled.

[0067] Step three, seed screening and sowing: the control module controls the seed screening unit to sow the large-grained Elymus salsa seeds and store the small-grained Elymus salsa seeds.

[0068] Step 4, soil monitoring and soil covering force adjustment: the monitoring unit monitors the temperature and humidity signals of the environment in real time, and the control module controls the soil covering wheel 24 in the soil covering module to move up and down to change the soil covering force according to the temperature and humidity signals of the environment. When the vehicle body 1 moves forward, the soil covering wheel 24 covers the sown large-grained saltwort seeds with soil.

[0069] The specific implementation process is as follows:

[0070] like Figure 4 As shown, first, the rear of the tractor is connected to the front end of the vehicle body 1 in the moving direction. The tractor is used to drive the vehicle body 1 to move to the position where the lymus is planted through the driving wheel 2, and at this time, the lymus seeds are added into the screen frame 14.

[0071] The user starts the controller, and the controller sends a control signal to control the first driving member in the transmission module to start. In this embodiment, the first driving member is a single-phase motor; at this time, the output shaft of the single-phase motor starts to rotate, which can drive the second sprocket wheel 8 and then drive the first chain 9 to rotate, and the first sprocket wheel 3 rotates through the transmission of the first chain 9; when the first sprocket wheel 3 rotates, it can drive the roller 5 and the rotary tillage teeth 6 in the rotary tillage frame 4 to rotate. During the forward movement of the vehicle body 1, when the rotary tillage teeth 6 come into contact with the soil, they can penetrate the soil and cut it into small pieces. The cut soil is thrown off the ground by the rotary tillage teeth 6 and turned over along the cutting direction, pushing the top layer of soil to the bottom layer, and the bottom layer of soil is pushed to the surface, thereby achieving soil mixing and tillage; through the high-speed rotating rotary tillage teeth 6, the land can be quickly broken and softened, thereby increasing the permeability and air permeability of the soil, making the soil loose, the seeds of the alkali grass are lighter and have weaker soil-breaking ability, and the loose soil is conducive to the soil-breaking of the alkali grass, creating better soil conditions for subsequent sowing and covering operations.

[0072] Then, since the vehicle body 1 can generate vibration during the forward movement, the vibration can vibrate and screen the Elymus salsa seeds in the screen frame 14. According to the needs of cultivation, the aperture of the screen with the required particle size is set. At this time, the small-grained Elymus salsa seeds can fall from the screen into the seed storage box 11 for storage with the vibration of the vehicle body 1, leaving the large-grained Elymus salsa seeds in the screen frame 14; Figure 2 and Figure 3 For example, after an interval of 120s, the controller sends a control signal to control the output shaft of the second driving member 12 to rotate 180° counterclockwise. In this embodiment, the second driving member 12 is a stepper motor. When the stepper motor rotates 180° counterclockwise, it can drive the rotating shaft 13 to rotate 180° counterclockwise and rotate the screen frame 14 180° counterclockwise with the rotating shaft 13 as the axis. At this time, the screen frame 14 opens to the sowing box 10, and the large-grained Elymus salsa seeds left after screening in the screen frame 14 are dumped into the sowing box 10. It is ensured that only large-grained Elymus salsa seeds are used for sowing, which improves the utilization rate and emergence rate of seeds. At the same time, the detachable design of the screen is convenient for replacing screens with different apertures, so that users can screen out Elymus salsa seeds of different particle sizes for sowing according to actual conditions.

[0073] by Figure 2 and Figure 4 For example, when the vehicle body 1 moves forward, since the plowing cover 22 is fixedly welded to the outer side wall of the lower part of the sowing tube 16, the plowing cover 22 can plow the soil into the sowing furrow as the vehicle body 1 moves forward; when large-grained Elymus salsa seeds fall into the bottom of the sowing box 10, since the bucket trough 15 is connected to the sowing box 10, the large-grained Elymus salsa seeds can fall into the bucket trough 15; since the second chain 19 is sleeved between the third sprocket wheel 18 and the second sprocket wheel 8, the second sprocket wheel 8 can drive the third sprocket wheel 18 to rotate through the second chain 19; Figure 3 , Figure 4 and Figure 5 For example, since the thumbwheel 20 is provided with a plurality of U-shaped holes 21, when the U-shaped holes 21 rotate to above the axle 17, the large-grained Elymus salsa seeds falling into the bucket 15 can fall into the U-shaped holes 21. As the U-shaped holes 21 rotate to below the axle 17, since the bottom of the bucket 15 is fixed by bolts and connected to the sowing tube 16, the large-grained Elymus salsa seeds in the U-shaped holes 21 can fall into the sowing furrow plowed by the plowing cover 22. The design of the U-shaped holes 21 driven to rotate by the axle 17 can evenly and intermittently sow the Elymus salsa seeds into the sowing furrow, thereby improving the uniformity of sowing. At the same time, the pressure sensor located on the bottom wall of the sowing box 10 can monitor the weight of the large-grained Elymus salsa seeds in the sowing box 10 in real time. When the weight of the large-grained Elymus salsa seeds is insufficient, the controller controls the single-phase motor and the stepper motor to stop rotating, so that the device stops running, thereby avoiding uneven sowing or missed sowing caused by insufficient large-grained Elymus salsa seeds.

[0074] by Figure 2 , Figure 3 and Figure 4 For example, after sowing large-grained alkali grass seeds into the sowing furrow, as the vehicle body 1 moves forward, since the bracket 23 is hinged on the rear end side wall of the vehicle body 1 in the moving direction and a plurality of grooves 25 are opened on the covering wheel 24 along its circumference, at this time, due to its own weight, when the covering wheel 24 rolls over the large-grained alkali grass seeds sown into the sowing furrow, the grooves 25 on the covering wheel 24 can evenly press the soil on both sides of the sowing furrow plowed by the plowing cover 22 back into the sowing furrow, and cover the seeds with soil, ensuring that the seeds are covered with an appropriate amount of soil, and the growth will not be inhibited due to excessive compaction, nor will the seeds be exposed to the external environment due to insufficient soil coverage.

[0075] by Figure 2 For example, the temperature and humidity sensor of the monitoring unit can send real-time temperature and humidity signals in the environment to the controller, and the controller controls the extension and retraction of the output shaft of the electric push rod 26 based on the temperature and humidity signals; since the output shaft of the electric push rod 26 is hinged to the bottom of the bracket 23, when the temperature in the environment is high and humid, the controller judges that the soil is relatively loose, and the controller will send a signal to control the output shaft of the electric push rod 26 to shorten, thereby driving the bracket 23 and the covering wheel 24 thereon to move downward. When the covering wheel 24 moves downward, it makes the covering wheel 24 closer to the ground, increasing the compactness of the covering soil, ensuring that the seeds are covered with sufficient and appropriately compacted soil, and improving the stability of the seeds.

[0076] When the temperature in the environment is low and dry, the soil may be relatively hard. At this time, the controller sends a control signal based on the temperature and humidity signals to control the extension of the output shaft of the electric push rod 26, thereby raising the height of the bracket 23 and the covering wheel 24 thereon, reducing excessive compaction of the soil by the covering wheel 24, and avoiding adverse effects of hard soil on seed growth.

[0077] Through automatic regulation, the cultivation system can flexibly adjust the soil covering operation according to different soil and environmental conditions to provide the best growth environment for Elymus salsa seeds.

[0078] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
