Description

Technical Field

[0001] The invention relates to the technical field of planting, and in particular to a regenerated rice sprout-promoting fertilization device. Background Art

[0002] The regenerated rice technology is a rice planting model, which is characterized by using the dormant buds on the rice piles to sprout again and grow ears after the first season of rice matures, and then harvesting the second season of rice. This technology has a long planting history in China, dating back to the Jin Dynasty 1,700 years ago, and has been applied and developed in China, India, Japan and other countries. The growth cycle of regenerated rice is relatively short, usually 60 to 70 days, so it has many advantages such as saving labor costs and improving economic benefits.

[0003] In the process of planting ratoon rice, the importance of uniform fertilization cannot be ignored. First of all, the growth of ratoon rice requires a lot of nutrient support, especially after the first season rice is harvested, the nutrients in the soil are often consumed in large quantities. At this time, timely and uniform fertilization is crucial for the growth of ratoon rice. Balanced fertilization, that is, regular and quantitative fertilization based on the optimal amount of fertilizer, can meet the nutrient needs of ratoon rice during its growth.

[0004] Uniform fertilization can provide the nutrients needed by the root system of regenerated rice and help the healthy development of the root system. Healthy root systems can better absorb water and nutrients from the soil, provide a solid foundation for the growth of regenerated rice, promote balanced growth of regenerated rice, and avoid poor growth caused by insufficient or excessive nutrients. This helps to improve the yield and quality of regenerated rice, increase farmers' economic benefits, enhance the stress resistance of regenerated rice, and reduce the occurrence of diseases and pests. Healthy plants are more resistant to the invasion of pathogens, thereby reducing the use of pesticides and reducing production costs.

[0005] In the prior art, operators often use fertilizer dispensers to apply fertilizer, but the design of fertilizer dispensers in some regenerated rice sprout-promoting fertilization devices may be insufficient, resulting in inaccurate and uneven fertilizer discharge, which will affect the utilization rate of fertilizers and further affect the growth and yield of regenerated rice.

[0013] Furthermore, the control system also includes a camera, which is used to collect image information of the rice field. The controller determines the difference between the actual landing position and the expected landing position of the fertilizer particles based on the image information of the rice field, thereby controlling the pump assembly and the solenoid valve to adjust the initial velocity of the fertilizer particles.

[0014] Furthermore, a plurality of baffles are hinged on the side walls of the hole, and the baffles are used to close the hole. The side walls of the baffles are provided with electromagnets, and the controller controls the operation of the electromagnets according to the image information.

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

[0034] The following is further described in detail through specific implementation methods:

[0035] Embodiment 1:

[0036] like Figure 1-Figure 6 As shown: a regenerated rice sprout-promoting fertilization device, comprising a frame 1, on which a fertilizer discharge component 3 is provided, the fertilizer discharge component 3 is used to fertilize the rice field, the fertilizer discharge component 3 comprises a plurality of fertilizer storage chambers 35 provided on the frame 1, the fertilizer storage chambers 35 are all connected with fertilizer discharge channels 31, the connection points between the fertilizer discharge channels 31 and the fertilizer storage chambers 35 are each provided with a first solenoid valve, the fertilizer storage chambers 35 are used to store fertilizer particles, and a fertilizer discharge platform 33 is provided below the output end of the fertilizer discharge channel 31, the fertilizer discharge platform 33 is welded and fixed to the frame 1, the fertilizer discharge channel 31 is used to make the fertilizer particles fall into the fertilizer discharge platform 33 in sequence, a pneumatic component is provided on the fertilizer discharge platform 33, the pneumatic component is used to give the fertilizer particles on the fertilizer discharge platform 33 an initial velocity, the pneumatic component comprises a pump component, in this embodiment, the pump component is an air pump, a plurality of holes 32 are provided on the fertilizer discharge platform 33, the holes 32 are all connected with the pump component, and a second solenoid valve is provided at the connection points between the holes 32 and the pump component.

[0037] There is also an adjustment component on the frame 1, which includes a transmission motor 5. The frame 1 includes a fixed part 11 and a rotating part 12. The bottom wall of the rotating part 12 is rotatably connected to the top wall of the fixed part 11. The transmission motor 5 is fixedly connected to the fixed part 11 by bolts. The output shaft of the transmission motor 5 passes through the fixed part 11 and is welded and fixed to the bottom of the rotating part 12. The transmission motor 5 is used to drive the fertilizer discharge platform 33 to change direction.

[0038] It also includes a control system, which includes a controller and several pressure sensors. The pressure sensors are fixedly connected to the fertilizer discharge platform 33 by bolts, and the controller is fixedly connected to the frame 1 by bolts. The pressure sensors are used to collect pressure information applied by fertilizer particles at various positions on the fertilizer discharge platform 33.

[0039] The control system also includes a camera 4, which is used to collect image information of the rice field. The camera 4 is fixedly connected to the frame 1 by bolts.

[0040] The pressure sensor, camera 4, pump assembly, second solenoid valve, first solenoid valve and transmission motor 5 are all electrically connected to the controller. The controller is used to receive the user's input of the paddy field fertilizer demand, the type and unit weight of the fertilizer particles in each fertilizer storage chamber 35, and judge the type of fertilizer particles falling into the fertilizer discharge platform 33 and the number of times the pressure information changes in unit time based on the position where the pressure information appears and the size of the pressure information, and then obtain the fertilizer amount. When the fertilizer amount is the same as the paddy field fertilizer demand, the pneumatic component is controlled to work.

[0041] The controller determines the difference between the actual landing position and the expected landing position of the fertilizer particles based on the image information of the rice field, thereby controlling the air flow intensity output by the pump assembly and the second solenoid valve working adjustment hole 32, and then adjusting the initial velocity of the fertilizer particles, and controlling the operation of the transmission motor 5 according to the difference between the actual landing position and the expected landing position of the fertilizer particles, adjusting the height of the initial position of the fertilizer particles, and then adjusting the actual landing position of the fertilizer particles; the controller is also used to control the operation of the first solenoid valve according to the fertilizer demand and fertilizer amount, thereby adjusting the fertilizer output.

[0042] The specific implementation process is as follows: when using the device, install the device on the ridge of the rice field, and adjust the angle of the device so that the output end of the fertilizer discharge platform 33 is roughly aligned with the central axis of the rice field.

[0043] Subsequently, fertilizer particles are placed into the fertilizer storage chamber 35 and the device is started. Subsequently, according to the type of fertilizer particles placed, the unit weight (i.e., the approximate weight of a single fertilizer particle) and the fertilizer demand for the paddy field (i.e., the size of the paddy field, and the type of fertilizer and the amount of each fertilizer required per unit area of ​​the paddy field), the controller controls the operation of the corresponding first solenoid valve according to the fertilizer demand for the paddy field. After the first solenoid valve is opened, the fertilizer particles in the corresponding fertilizer storage chamber 35 enter the corresponding fertilizer discharge channel 31 in turn under the action of gravity. Due to the limiting effect of the fertilizer discharge channel 31, the fertilizer particles fall onto the fertilizer discharge platform 33 in turn and hit the fertilizer discharge platform 33 in turn.

[0044] At the same time, the pressure sensor continuously collects the pressure information applied by the fertilizer particles on the fertilizer discharge platform 33, and combines the position and size of the pressure information for analysis. Since the distance between the output end of the fertilizer discharge channel 31 and the top wall of the fertilizer discharge platform 33 is known, and the weight of a single fertilizer particle is known, the theoretical impact force of the fertilizer particles when they hit the fertilizer discharge platform 33 can be calculated. At the same time, combined with the same external factors such as wind speed, the range of impact force of different fertilizer particles when they hit the fertilizer discharge platform 33 can be obtained.

[0045] Therefore, based on the size of the pressure information, the controller can estimate the type of fertilizer particles that hit the fertilizer discharge platform 33. When the unit weight of the fertilizer particles is similar, the position where the pressure information appears can be used to determine which part of the fertilizer discharge channel 31 the fertilizer particles that impact the fertilizer discharge platform 33 are discharged from. By selecting the intersection with the fertilizer particles of similar weight, the type of fertilizer entering the fertilizer discharge platform 33 can be obtained.

[0046] When the fertilizer particles enter the fertilizer discharge platform 33, the controller controls the pump assembly and the second solenoid valve near the position where the pressure information appears to work, and the pump assembly pumps gas into the corresponding hole 32. The impact force of the airflow acts on the fertilizer particles, thereby giving the fertilizer particles an initial velocity, so that the fertilizer can move into the rice field. According to the unit weight of the fertilizer particles and the size of the initial velocity, the position where the fertilizer particles will eventually fall into the rice field can be estimated. Therefore, the controller can adjust the position where the fertilizer particles fall into the rice field by controlling the working power of the pump assembly, thereby realizing fertilization at different positions of the rice field, such as far, middle and near.

[0047] After obtaining the type of fertilizer particles, the frequency of occurrence of the pressure information at that position is calculated, that is, the number of times the pressure information appears per unit time. For example, if fertilizer particle A hits the fertilizer discharge platform 33b times within 1 minute, the frequency of occurrence of the pressure information corresponding to the fertilizer particle is b times / min. Based on the position facing the output end of the fertilizer discharge platform 33 at this time and the position where the fertilizer particles fall into the rice field, the amount of fertilizer applied per unit area in the rice field can be calculated, and the uniform spreading of the fertilizer can be achieved by gradually adjusting the working power of the pump assembly.

[0048] During this process, the controller controls the transmission motor 5 to work, and the transmission motor 5 drives the fertilizer discharge platform 33 to rotate, so that the fertilizer particles can fall into other positions of the rice field with the fertilizer discharge platform 33 as the center and the movement distance of the fertilizer particles as the radius, thereby adjusting the left and right angles of the fertilization position to meet the fertilization needs of rice fields of different widths.

[0049] At the same time, the camera 4 continuously collects image information of the rice field. According to the image information, the controller can identify the boundary of the rice field. When the controller controls the transmission motor 5 to work, when the fertilizer particles are about to fall into the edge of the rice field, the controller controls the transmission motor 5 to drive the fertilizer discharge component 3 to rotate in the opposite direction, and controls the pump component to work, so that the fertilizer particles move in a farther direction or a closer direction, so as to avoid discharging fertilizer outside the rice field and causing fertilizer waste. The controller can also estimate the theoretical landing position of the fertilizer particles according to the initial position of the fertilizer discharge platform 33 and the power and time of the transmission motor 5, combined with the power of the pump assembly and the weight of the fertilizer particles, and obtain the actual landing position of the fertilizer particles through image information (because the fertilizer particles are discharged quickly and continuously during the fertilizer discharge process, the fertilizer particles are in a parabolic state in the image information, and the actual landing position of the fertilizer particles can be judged according to the position where the parabola contacts the paddy field). According to the theoretical landing position and the actual landing position, the influence of the external environment such as wind speed on the movement of the fertilizer particles is judged, and according to the above influence, the pump assembly and the second solenoid valve are controlled to work, and the magnitude of the impact force of the subsequent output airflow on the same type of fertilizer particles is adjusted, thereby adjusting the initial velocity of the subsequent similar fertilizer particles. For example: when the actual landing position is close to the theoretical landing position, the influence of the external force environment on the fertilizer particles is negative, and the controller increases the working power of the pump assembly to increase the initial velocity of the subsequent fertilizer particles.

[0050] Compared with the existing technology, this solution can predict the fertilizer particles entering the fertilizer discharge platform 33, thereby improving the accuracy and uniformity of subsequent fertilization. At the same time, compared with the solution that only uses the position where the pressure information appears to identify the type of fertilizer particles, this solution can reduce the misjudgment caused by the deviation of fertilizer particles during the falling process caused by external forces such as wind.

[0051] During the fertilizer discharge process, the controller determines whether a certain fertilizer has met the fertilizer demand of the rice field based on the fertilizer demand and the fertilizer amount. When the fertilizer amount of a certain fertilizer meets the fertilizer demand, the controller controls the first solenoid valve to close and terminate the discharge of the fertilizer to avoid causing excessive fertility in the rice field and causing subsequent problems such as seedling burn.

[0052] Embodiment 2:

[0053] As attached Figure 1 As shown, the difference from Example 1 is that a plurality of baffles 34 are hinged on the side walls of the hole 32, the baffles 34 are used to close the hole 32, and the side walls of the baffles 34 are provided with electromagnets 341, which are electrically connected to the controller, and the controller controls the operation of the electromagnets 341 according to the image information.

[0054] The specific implementation process is as follows: when using the device, when only a slight adjustment is needed in the landing position of the fertilizer particles, or the position where the fertilizer particles fall into the fertilizer discharge component 3 deviates from the center position of the hole 32, and the airflow hits the fertilizer discharge component 3, it is difficult to give the fertilizer particles a sufficient initial velocity. The controller controls the electromagnet 341 to turn on, and the electromagnet 341 generates a magnetic force and attracts each other, so that the baffle 34 closes the hole 32. Then the controller determines the direction in which the fertilizer particles need to be adjusted according to the image information, and cuts off the current of the electromagnet 341 in the opposite direction of the direction, so that the blocking effect of the baffle 34 on the hole 32 at this position is released, and the gas impacts the fertilizer particles through the position of the baffle 34, thereby changing the trajectory of the fertilizer particles. At the same time, since the gas outlet becomes smaller, the gas pressure also increases, and the impact force on the fertilizer particles also increases accordingly, thereby giving the fertilizer particles a sufficient initial velocity.

[0055] For example, when the fertilizer particles need to move to the right, the current of the electromagnet 341 on the left baffle 34 is turned off, so that the position covered by the left baffle 34 is opened, and the gas is ejected through the position corresponding to the left baffle 34, acting on the left side of the fertilizer particles, and the fertilizer particles move forward in hand and rotate to the right, thereby changing the movement direction of the fertilizer particles.

[0056] Compared with the prior art, this solution can achieve a small adjustment of the movement direction of the fertilizer particles, and compared with the solution of only using the transmission motor 5 to adjust the movement direction of the fertilizer particles, this solution has higher adjustment accuracy, thereby further ensuring the uniformity of fertilization, and at the same time, it also reduces the opening and closing of the transmission motor 5 during the use of the device, which is beneficial to reducing the energy consumption of the device and saving the use cost. At the same time, it can also reduce the loss of the transmission motor 5 caused by frequent opening and closing of the transmission motor 5, thereby extending the service life of the device.

[0057] Embodiment 3:

[0058] As attached Figure 1 As shown, the difference from Example 2 is that it also includes an alarm, which is electrically connected to the controller. The controller is also used to determine whether the fertilizer particles are stuck based on the size of the pressure information, the location where it appears, the unit weight of the fertilizer particles, and the storage location of the fertilizer particles, and when the fertilizer particles are stuck, control the alarm to warn the user.

[0059] The specific implementation process is as follows: During the use of this device, after the controller locates the type of fertilizer particles according to the size of the pressure information and the location where it appears, during subsequent use, the controller continues to monitor the state of the fertilizer particles according to the size of the pressure information. When the pressure information appears multiple times in a row or increases intermittently multiple times, and the amount of increase is much larger than the normal pressure information value (such as more than five times), fertilizer adhesion may occur at this time. The controller controls the alarm to sound an alarm, prompting the user to check the remaining fertilizer particles in the fertilizer storage chamber 35 to determine whether they are damp and adhered, and to take timely measures after the above problems occur.

[0060] Compared with the existing technology, this solution can monitor the state of fertilizer particles to avoid adhesion of fertilizer particles. The fertilizer may find it difficult to move the set distance at the original initial speed, or cause the controller to misjudge, affecting the subsequent discharge of fertilizer particles.

[0061] Embodiment 4:

[0062] As attached Figure 1 As shown, the difference from Example 3 is that it also includes a monitoring component 2, which includes a monitoring ball 22. A connecting line 21 is bonded and fixed to the outer wall of the monitoring ball 22, and the other end of the connecting line 21 is fixedly connected to the frame 1. A soil comprehensive sensor is arranged in the monitoring ball 22. The model of the soil comprehensive sensor in this embodiment is preferably GH-TRZH. The soil comprehensive sensor is used to collect the temperature, humidity, pH value, conductivity, nutrient content and soil texture of the paddy field soil. The soil comprehensive sensor is electrically connected to the controller, and the controller adjusts the fertilizer demand for the paddy field according to the temperature, humidity, pH value, conductivity, nutrient content and soil texture of the paddy field soil.

[0063] The specific implementation process is as follows: before using this device, place the monitoring ball 22 on the fertilizer discharge platform 33, then start the pump assembly and the second solenoid valve, and under the impact force of the gas, the monitoring ball 22 is placed in the rice field. When the monitoring ball 22 is placed in the rice field, the soil comprehensive sensor starts to work and collects information such as soil temperature, humidity, pH value, conductivity, nutrient content and soil texture.

[0064] During the use of this device, when the operator inputs the fertilizer demand of the rice field into the controller, the controller adjusts the fertilizer demand of the rice field according to the actual temperature, humidity, pH value, conductivity, nutrient content and soil texture of the rice field.

[0065] For example, in the fertilization demand for rice fields, phosphate fertilizer needs to be sprayed on the rice fields. However, the data collected by the soil comprehensive sensor shows that the soil of the rice fields is sufficient in phosphorus. If phosphate fertilizer is continued to be applied to the rice fields at this time, it is easy to cause soil and water pollution. At this time, the controller will intermittently reduce the amount of phosphate fertilizer applied in the rice fields to avoid the above situation.

[0066] Compared with the existing technology, this solution can monitor the actual soil conditions in the rice field in advance before fertilization, and adjust the operator's fertilization plan according to the monitoring results, thereby avoiding fertilizer allocation errors caused by insufficient assessment of the rice field conditions by the operator in the early stage, which affects the promotion of regenerated rice germination.

[0067] 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.
