Description

Technical Field

[0001] The invention relates to the field of ecological environment restoration, and in particular to a reseeding device for grassland ecological restoration. Background Art

[0002] As one of the most important ecosystems on Earth, grassland ecosystem plays an irreplaceable role in maintaining ecological balance, protecting biodiversity and promoting the development of animal husbandry. However, due to the influence of multiple factors such as overgrazing, climate change and soil erosion, grassland ecosystem faces serious degradation problems. In order to restore and repair damaged grassland ecosystems, people have taken a variety of measures, among which reseeding is a common and effective method.

[0003] Traditional grassland ecological restoration reseeding methods mainly rely on manual operations, including determining the reseeding area, preparing grass seeds, turning the soil, sowing grass seeds, and subsequent covering and maintenance. This method is not only time-consuming and labor-intensive, but also easily affected by human factors, resulting in uneven reseeding results. In addition, due to the lack of scientific monitoring and evaluation methods, it is difficult to accurately judge the ecological recovery of grasslands after reseeding, which affects the pertinence and effectiveness of restoration work.

[0004] In recent years, with the continuous development of agricultural mechanization and intelligent technology, people have begun to try to apply advanced mechanical equipment and intelligent control systems to grassland ecological restoration and reseeding. These devices usually have the advantages of high degree of automation, high operating efficiency, and high precision, which can greatly improve the efficiency and accuracy of reseeding. However, most of the grassland ecological restoration and reseeding devices on the market currently have single functions and lack a comprehensive monitoring and evaluation system, which cannot achieve real-time monitoring of grassland ecological conditions and accurate reseeding.

[0005] Therefore, in response to the problems existing in the prior art, the present invention proposes a device for grassland ecological restoration and reseeding, which adopts advanced mechanical structure and intelligent control system, can monitor the grassland ecological status in real time, and automatically start the reseeding operation according to the demand data, thereby greatly improving the restoration efficiency and accuracy.

[0010] Furthermore, the locking member includes a first cover plate and a second cover plate, and the first cover plate and the second cover plate are hinged to the side walls on both sides of the opening respectively. The first cover plate and the second cover plate are cooperated with the side away from the opening to install an electromagnet, and the electromagnet is connected to the controller signal. The controller activates the electromagnet according to the location data monitored in real time by the monitoring unit, so as to close and open the opening.

[0011] Furthermore, the covering unit comprises a mounting rod, on which a covering plate is hinged.

[0012] Furthermore, the trigger component includes a pressure sensor, which is connected to the controller signal. The pressure sensor is installed under the plow claw of the tillage component to detect whether the plow claw contacts and turns the grass soil. When the pressure sensor detects a pressure change, the signal is transmitted to the controller. The controller determines whether the grass has been turned over according to the pressure data monitored in real time by the pressure sensor.

[0017] The technical principle of the above scheme is as follows: The present invention provides a device for grassland ecological restoration and reseeding, which integrates multiple functions such as monitoring, tilling, sowing, covering and re-inspection, aiming to achieve efficient and accurate restoration of grassland ecology. The bottom of the vehicle body of the present invention is equipped with a driving unit to drive the device to move, and is also equipped with a monitoring unit, a reseeding unit (tillage component and sowing component), a covering unit and a re-inspection component, and each part is intelligently controlled by a controller.

[0018] The above scheme has the following beneficial effects: 1. This solution monitors the grassland ecological status in real time through the monitoring unit, and automatically starts the reseeding device to move to the grassland that needs to be repaired according to the demand data, realizing the intelligent and automated grassland ecological restoration. Compared with the manual or semi-automatic reseeding method in the prior art, it greatly improves the restoration efficiency and accuracy.

[0019] 2. This solution utilizes the plow claw and eccentric roller structure in the tillage assembly to till the grass under the drive of the first driving member. The plow claw is connected to the eccentric roller through a connecting rod, and swings up and down with the rotation of the eccentric roller, effectively loosening the soil and providing a good soil environment for the growth of grass seeds. Compared with the simple sowing method in the prior art, this structural design not only improves the tillage efficiency, but also helps to improve the germination rate and survival rate of grass seeds, thereby enhancing the restoration effect of the grassland ecology.

[0020] 3. In this solution, the sowing component automatically opens the sowing port to sow grass seeds after detecting that the grass has been turned over through the cooperation of the power parts and the trigger component, thereby achieving precise control of the sowing operation, avoiding waste and omission of grass seeds, and further improving the reseeding effect compared with the fixed sowing method in the prior art.

[0021] 4. This solution achieves uniform sowing of grass seeds through the staggered arrangement of the first and second sieve plates and the holes of different diameters. The second driving member drives the slider and the second sieve plate to move left and right through the connecting plate and the connecting rod, so that the grass seeds are evenly distributed on the sieve plate and fall into the soil. This design not only improves the sowing efficiency, but also ensures that the grass seeds can be evenly distributed on the grass, avoiding the occurrence of missed sowing and re-seeding.

[0022] 5. This solution also includes additional functions such as quantity control components, auxiliary components, remote control units and re-inspection components, which further enhance the intelligence and automation level of grassland ecological restoration reseeding devices. The quantity control component can monitor and adjust the flow of grass seeds in real time to ensure the accuracy of the sowing amount; the auxiliary component provides additional support and cushioning for the screen plate through the design of air bags and air outlet pipes; the remote control unit enables operators to remotely monitor and control the reseeding device away from the reseeding device; the re-inspection component detects the distribution of grass seeds in real time through cameras and image processing modules to ensure the accuracy and consistency of the reseeding effect. Compared with the reseeding devices in the prior art, these additional functions not only improve the convenience and flexibility of operation, but also enhance the reseeding effect and the sustainability of ecological restoration.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The following is further described in detail through specific implementation methods: Embodiment 1:

[0030] As attached Figures 1 to 6 As shown: a grassland ecological restoration and reseeding device, including a vehicle body 1 and a controller, a driving unit is installed at the bottom of the vehicle body 1, the driving unit includes a plurality of first driving members, the first driving members are fixedly connected to the bottom of the vehicle body 1, both sides of the output shaft 201 of the first driving member are coaxially fixedly connected with rollers 3, the rollers 3 are respectively installed on both sides of the vehicle body 1, and a monitoring unit, a reseeding unit and a covering unit for covering grass seeds with soil are installed in sequence from front to back at the bottom of the vehicle body 1; the monitoring unit includes a soil moisture sensor, a soil pH sensor, a vegetation coverage sensor and a GPS positioning module.

[0031] The overseeding unit includes a tillage component 4 and a sowing component. The tillage component 4 includes an outer shell 401. The outer shell 401 is a hollow structure. Both ends of the outer shell 401 are fixedly connected to the output shaft 201 of the first driving member. A plurality of openings 402 are opened on the outer shell 401. Locking members are installed at the openings 402. A plurality of plow claws 403 equal in number to the openings 402 are hinged on the outer shell 401. The plow claws 403 are hinged with connecting rods 404 at one end away from the outer shell 401. The connecting rods 404 are hinged with sleeves 405 at one end away from the plow claws 403. An eccentric roller 406 is embedded in the sleeve 405. The eccentric roller 406 is fixedly connected to the output shaft 201 of the first driving member, and the center position of the eccentric roller 406 is vertically below the output shaft 201. The locking member includes a first cover plate and a second cover plate. The first cover plate and the second cover plate (not shown in the figure) are respectively hinged to the side walls on both sides of the opening 402. The first cover plate and the second cover plate are equipped with electromagnets on the side away from the opening 402. The electromagnets are connected to the controller signal. The controller starts the electromagnets according to the location data monitored in real time by the monitoring unit to close and open the opening 402. When it is necessary to turn the soil, the controller controls the electromagnets to be powered off. After the magnetic force disappears, the first cover plate and the second cover plate are opened to expose the opening 402, so that the plow claw 403 can extend from the opening 402. When it is not necessary to turn the soil, the controller controls the electromagnets to be powered on, the magnetic force is restored, the first cover plate and the second cover plate are locked, and the opening 402 is closed, so that the plow claw 403 cannot extend from the opening 402.

[0032] The sowing assembly is used to sow grass seeds on the lawn. The sowing assembly is installed inside the vehicle body 1. The bottom wall of the vehicle body 1 is provided with a sowing port 101. The sowing port 101 is slidably matched with a cover 102 for closing the sowing port 101. A power part and a trigger assembly are installed at the connection between the cover 102 and the bottom wall of the vehicle body 1. The trigger assembly includes a pressure sensor, which is connected to the controller signal. The pressure sensor is installed below the plow claw 403 of the tilling assembly 4 to detect whether the plow claw 403 contacts and turns the lawn soil. When the pressure sensor detects a pressure change, the signal is transmitted to the controller. The controller determines whether the lawn has been turned over according to the pressure data monitored in real time by the pressure sensor; if the judgment result is that the lawn has been turned over, the controller starts the power part to open the sowing port 101. That is, before the vehicle body 1 starts working, the pressure sensor will be initialized and the initial pressure value will be set to zero or a certain reference value. This value represents the pressure on the sensor when there is no soil turning.

[0033] When the vehicle body 1 drives the tilling assembly to start tilling the soil, the plow claw 403 will insert into the soil and turn it over. During this process, the plow claw 403 will apply a certain pressure to the soil, and this pressure will be transmitted to the pressure sensor through the soil. The pressure sensor will continuously monitor the pressure and transmit these pressure data to the controller of the vehicle body 1 in real time. The controller will analyze these pressure data, especially paying attention to the changes in the pressure value. If the controller detects that the pressure value has increased significantly in a short period of time (for example, exceeding a preset threshold), this usually means that the plow claw 403 has contacted and turned the soil.

[0034] Based on the above pressure data analysis, the controller can determine whether the lawn has been turned over. Once the controller determines that the lawn has been turned over, it will immediately send a signal to the power member, which will open the sowing port 101 to allow grass seeds to fall from the sowing port 101 into the turned soil.

[0035] The sowing assembly includes a mounting plate 6, a grass seed storage box 5 is fixedly connected to the inner top wall of the vehicle body 1, a feed port and a discharge port are respectively provided at the top and bottom of the grass seed storage box 5, the mounting plate 6 is located below the grass seed storage box 5, and is fixedly connected to the inner wall of the vehicle body 1, a first slide groove 601 and a second slide groove 602 are provided on the mounting plate 6, a second driving member is installed in the first slide groove 601, a slider 8 is installed in the second slide groove 602, first springs 701 are fixedly connected between the second driving member and the first slide groove 601 on both sides, and second springs 801 are fixedly connected between the slider 8 and the second slide groove 602 on both sides. The output shaft 201 of the second driving member is coaxially fixedly connected with a connecting plate 702, a connecting rod 703 is hingedly connected to the connecting plate 702 on the side away from the second driving member, the connecting rod 703 is hingedly connected to the slider 8 on the end away from the connecting plate 702, the second driving member is fixedly connected with a first sieve plate 9 on the side away from the connecting plate 702, the slider 8 is fixedly connected with a second sieve plate 10 on the side away from the connecting rod 703, the first sieve plates 9 and the second sieve plates 10 are staggered and clearance-matched, leakage holes 11 are provided on the first sieve plates 9 and the second sieve plates 10, and the diameter of the leakage holes 11 on the first sieve plate 9 is larger than the diameter of the leakage holes 11 on the second sieve plate 10.

[0036] The first driving member, the second driving member and the power member are all connected to the controller signal; the soil moisture sensor and the soil pH sensor are installed at the bottom of the vehicle body 1 and located in front of the soil turning component 4, and are used to monitor the moisture and pH of the grassland soil in real time; the vegetation coverage sensor is installed on the top wall of the vehicle body 1, and is used to monitor the vegetation coverage on the grassland surface; the GPS positioning module is integrated in the controller, and is used to accurately record the location information of the reseeding device; the soil moisture sensor, the soil pH sensor, the vegetation coverage sensor and the GPS positioning module all transmit the monitored data to the controller, and the controller analyzes and determines whether the reseeding device needs to be started according to the preset ecological restoration standards and the current location information.

[0037] When the monitoring unit detects that the grassland ecology needs to be repaired, the controller starts the first drive member according to the demand data monitored in real time in the monitoring unit, and the first drive member drives the reseeding device to move to the grassland that needs to be repaired; when the monitoring unit detects that the reseeding device moves to the grassland that needs to be repaired, the controller starts the locking member according to the location data monitored in real time by the monitoring unit, and the first drive member drives the reseeding device to move while driving the tillage component 4 to till the grassland that needs to be repaired; when the trigger component detects that the grassland has been over-turned, the controller starts the power member according to the data monitored in real time by the trigger component, the power member opens the sowing port 101, and the sowing component sows grass seeds on the grassland that needs to be repaired.

[0038] In this embodiment, the first driving member is the first motor 2 , the second driving member is the second motor 7 , and the power member is the electric cylinder 103 .

[0039] The specific implementation process is as follows: First, the operator transports the reseeding device of this embodiment to the vicinity of the grassland that needs ecological restoration, and ensures that the device is in the initial state, that is, all sensors, driving parts and power parts are not started, and the sowing port 101 is closed by the cover 102. Before starting the reseeding device, the operator needs to set a series of parameters in the controller, including but not limited to ecological restoration standards (such as soil moisture, pH value, target range of vegetation coverage), travel speed, tillage depth, sowing amount and possible soil cover thickness. These parameters should be determined according to the specific grassland ecological restoration needs and grassland status.

[0040] During the movement of the reseeding device, when the soil moisture sensor, soil pH sensor, and vegetation coverage sensor in the monitoring unit start working, they will monitor the moisture, pH value, and vegetation coverage of the grassland soil in real time, and transmit the data to the controller. The controller analyzes and determines whether the reseeding device needs to be started based on the preset ecological restoration standards and the current location information (provided by the GPS positioning module). If the judgment result is that it needs to be started, the controller starts the first driving member (i.e., the first motor 2), and the first motor 2 drives the roller 3 to rotate, thereby driving the reseeding device to move to the grassland that needs to be repaired. The GPS positioning module will record the location information of the reseeding device in real time and compare it with the preset repair area to ensure that the reseeding device can accurately reach the target area.

[0041] When the monitoring unit detects that the reseeding device moves to the grass that needs to be repaired, the controller activates the locking member (i.e., the electromagnet on the first cover plate and the second cover plate) according to the real-time monitored location data. After the electromagnet is powered off and the magnetic force disappears, the first cover plate and the second cover plate are opened to expose the opening 402 on the housing 401.

[0042] At the same time, the first motor 2 continues to drive the reseeding device to move, and drives the housing 401 of the tilling assembly 4 to rotate. Since the center position of the eccentric roller 406 is vertically below the output shaft 201, as the output shaft 201 rotates, the housing 401 drives the sleeve 405 to rotate, and when the sleeve 405 rotates, it rotates around the fixed eccentric roller 406, driving the connecting rod 404 and the plow claw 403 to do reciprocating motion, and the plow claw 403 expands and contracts at the opening 402 to turn over the grass soil.

[0043] When the pressure sensor in the trigger assembly detects that the plow claw 403 contacts and turns the lawn soil, it transmits a signal to the controller. The controller determines whether the lawn has been turned over based on the pressure data monitored in real time by the pressure sensor. If the result of the judgment is that the lawn has been turned over, the controller starts the power part (i.e., the electric cylinder 103). The electric cylinder 103 pushes the cover 102 to slide and open the sowing port 101.

[0044] At the same time, the controller starts the second driving member (i.e., the second motor 7). The output shaft 201 of the second motor 7 drives the connecting plate 702 to rotate, and the connecting plate 702 drives the slider 8 to reciprocate through the connecting rod 703. Because of the setting of the first spring 701 and the second spring 801, the reset force of the second spring 801 plays an auxiliary role while the slider 8 slides in the second chute 602. At the same time, the reset force of the first spring 701 causes the second motor 7 to move back and forth in the first chute 601, and the moving direction of the second motor 7 is opposite to the moving direction of the slider 8, so a relative movement is formed between them. This relative movement will drive the first sieve plate 9 and the second sieve plate 10 to move back and forth while they move, so the grass seeds will be evenly sown from the storage box through the gap between the first sieve plate 9 and the second sieve plate 10 to the turned over grass.

[0045] When the reseeding device completes the ecological restoration reseeding task in the designated area, the controller stops the operation of all driving parts and power parts and closes the sowing port 101. Finally, the operator transports the reseeding device back to the base or the next work site.

[0046] Embodiment 2:

[0047] As attached Figure 4 As shown, the difference from the embodiment 1 is that the covering unit comprises a mounting rod, and a covering plate 12 is hingedly connected to the mounting rod.

[0048] The specific implementation process is as follows: when the sowing assembly completes the sowing of grass seeds, the covering plate 12 moves with the vehicle body 1, and the soil is gently scraped up and covered on the grass seeds, forming a thin soil covering layer. This covering layer helps to maintain soil moisture, provide a suitable growth environment for the grass seeds, and ensure that the grass seeds can grow well in the soil.

[0049] Embodiment 3:

[0050] The difference from Example 2 is that a quantity control component (not shown in the figure) is installed at the outlet of the grass seed storage box 5, and the quantity control component includes a regulating valve and a flow sensor. The regulating valve and the flow sensor are both connected to the controller signal. The regulating valve is used to adjust the speed at which the grass seeds flow out of the outlet of the grass seed storage box 5 (the amount of grass seeds flowing out per unit time), and the flow sensor is used to monitor the flow of the grass seeds in real time; when the flow data monitored by the flow sensor in real time is abnormal, the abnormal signal is transmitted to the controller, and the controller adjusts the different openings of the regulating valve according to the abnormal signal.

[0051] The specific implementation process is as follows: Before starting the reseeding device, the operator needs to initialize the control components. This includes checking the connection status of the regulating valve and flow sensor to ensure that the signal transmission between them and the controller is normal. According to the needs of ecological restoration and the actual situation of the grassland, the flow range of the grass seed is preset in the controller. This range will serve as the basis for flow sensor monitoring and regulating valve adjustment.

[0052] When the reseeding device starts working, the grass seeds flow out from the outlet of the grass seed storage box 5 and pass through the quantity control component. The flow sensor monitors the flow of the grass seeds in real time and transmits the data to the controller in real time. The controller processes and analyzes the received flow data to determine whether the current flow is within a preset range.

[0053] If the flow data detected by the flow sensor is abnormal (i.e., outside the preset range), the controller will immediately identify this abnormal signal. According to the nature of the abnormal signal (high or low), the controller will automatically adjust the opening of the regulating valve. If the flow is high, the controller will reduce the opening of the regulating valve to reduce the outflow speed of the grass seeds; if the flow is low, the controller will increase the opening of the regulating valve to increase the outflow speed of the grass seeds. The controller will also continuously monitor the data of the flow sensor to ensure that the adjustment of the regulating valve can achieve the expected flow control effect.

[0054] During the entire reseeding process, the controller will dynamically adjust the opening of the regulating valve according to the real-time monitoring data of the flow sensor to maintain the stability of the grass seed flow. If the data monitored by the flow sensor continues to be abnormal and the controller cannot solve the problem by adjusting the regulating valve, the controller will issue an alarm signal to prompt the operator. The operator can troubleshoot and repair the control component according to the alarm signal and the prompt of the controller to ensure that the reseeding device can continue to work normally.

[0055] When the reseeding device completes the ecological restoration reseeding task in the designated area, the controller will stop the operation of all related components. The operator can reset the control component to restore it to its initial state for the next reseeding work.

[0056] Embodiment 4:

[0057] The difference from Example 3 is that auxiliary components are installed in the first slide groove 601 and the second slide groove 602, and the auxiliary components include a plurality of air bags (not shown in the figure), and the air bags are all mounted on the outside of the first spring 701 and the second spring 801, and the air bags are connected to air outlet holes, and the air outlet holes are connected to air outlet pipes, and the end of the air outlet pipe away from the air outlet holes is fixed above the first screen plate 9.

[0058] The specific implementation process is as follows: During the grass seed reseeding process, the first spring 701 and the second spring 801 will drive the airbags set outside the first spring 701 and the second spring 801 to inflate and deflate during the process of accumulating and releasing. When the first spring 701 and the second spring 801 are released, the airbags on the outside are expanded, and the inside thereof is filled with air as it expands. When the first spring 701 and the second spring 801 accumulate power, the airbags on the outside are compressed, and the gas inside thereof is blown out through the air outlet. This airflow with a certain speed and pressure is like a miniature storm, and the gas can effectively blow the grass seeds on the first sieve plate 9 and the second sieve plate 10 through the air outlet pipe. Driven by the airflow, these grass seeds will more easily fall from the surface of the first sieve plate 9 and the second sieve plate 10.

[0059] Embodiment 5:

[0060] The difference from Example 4 is that it also includes a remote control unit (not shown in the figure), the remote control unit includes a wireless communication module and a mobile control terminal (the mobile control terminal in this embodiment is usually a smart phone, a tablet computer or a dedicated control device, ensuring that it can support the communication protocol used by the wireless communication module), the mobile control terminal is connected to the controller signal through the wireless communication module, the mobile control terminal is used to remotely monitor the working status of the overseeding device, and is also used to remotely control and adjust parameters of the overseeding device.

[0061] The specific implementation process is as follows: Install a wireless communication module on the reseeding device and ensure that the signal connection between it and the controller is stable and reliable. Install dedicated control software or application on the mobile control terminal. The software or application should be compatible with the controller of the reseeding device and have the function of remote monitoring and control.

[0062] The operator can view the working status of the reseeding device in real time through the control software or application on the mobile control terminal. The status information includes but is not limited to the device's operating speed, grass seed flow, tillage depth, sowing range, remaining grass seed amount and battery power. The control software or application displays this information in a graphical interface, allowing the operator to intuitively understand the operation of the reseeding device.

[0063] The operator can remotely control the reseeding device through the control software or application on the mobile control terminal. The remote control functions include but are not limited to starting / stopping the device, adjusting the operating speed, changing the tillage depth, adjusting the grass seed flow rate, and setting the sowing range. The operator can also adjust the parameters of the reseeding device through the mobile control terminal according to actual needs. For example, the preset ecological restoration standards can be modified, and the sowing density of grass seeds can be adjusted.

[0064] If the reseeding device fails or experiences an abnormality during operation, the controller will send an alarm signal to the mobile control terminal through the wireless communication module. After receiving the alarm signal, the operator can view detailed fault information through the mobile control terminal and take appropriate measures according to the type of fault. For some simple faults, the operator can repair them through the remote control function; for complex faults, on-site inspection and processing are required.

[0065] Embodiment 6:

[0066] The difference from Example 5 is that it also includes a re-inspection component (not shown in the figure), which is installed between the reseeding unit and the soil covering unit at the bottom of the vehicle body 1, and includes a camera and an image processing module, both of which are connected to the controller signal; the camera is used to photograph the grassland after sowing, and the image processing module is used to analyze the pictures taken by the camera in real time to detect whether the distribution of grass seeds is uniform, and whether there is any omission or re-seeding; the controller adjusts the sowing strategy according to the detection results of the image processing module.

[0067] The specific implementation process is as follows: During the entire reseeding process, the re-inspection component will continue to work, capturing and analyzing the grass conditions in real time. When the reseeding device moves on the grass and sows grass seeds, the camera will capture the grass conditions after sowing in real time, and the pictures taken by the camera will be immediately transmitted to the image processing module for processing and analysis. After receiving the pictures taken by the camera, the image processing module will perform pre-processing, including denoising, contrast enhancement, etc., to improve the image quality. Then, the image processing module will use image recognition and analysis algorithms to detect the distribution of grass seeds in the picture. This includes judging whether the grass seeds are evenly distributed and whether there are obvious missed or reseeded areas. The image processing module sends the detection results to the controller in the form of a signal.

[0068] After receiving the detection results from the image processing module, the controller will dynamically adjust the sowing strategy according to the preset algorithm and logic. If it detects that the grass seeds are unevenly distributed, or there are missed or repeated sowing, the controller will adjust the working parameters of the reseeding unit and the covering unit to improve the distribution of the grass seeds. The adjusted parameters may include sowing speed, sowing amount, and covering depth.

[0069] 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.
