Description

Technical Field

[0001] This invention relates to the field of rice cultivation technology, and in particular to a device for measuring greenhouse gas emissions from rice cultivation to reduce fertilizer use. Background Technology

[0002] Greenhouse gases are gases that exist in the atmosphere and can absorb radiation emitted from the Earth's surface and from the sun, remaining on Earth for a relatively long period and producing a significant greenhouse effect. When applying fertilizer to rice paddies, it is necessary to test the greenhouse gas emissions in the paddy fields. The conventional testing method usually involves placing the measuring instrument on a cart, which is then pushed by the testing personnel through the paddy field, and the measuring instrument is used to test the greenhouse gas content in the paddy field during the process. Although existing devices can conveniently complete the greenhouse gas content test, it is difficult to get close to the paddy field when measuring on the ground, making it difficult to obtain the greenhouse gas content in the water area where the rice grows. On the other hand, it is also inconvenient to measure directly in the paddy field.

[0003] Therefore, in response to the above problems, a greenhouse gas emission measurement device for rice fertilization is being developed that can automatically travel within paddy field waters and approach rice plants to measure their emissions. Summary of the Invention

[0004] To overcome the shortcomings of existing devices that cannot get close to rice paddies when measuring on the ground and are difficult to obtain greenhouse gas content in the rice growing area, and that measuring directly in the rice paddy is inconvenient, this invention provides a greenhouse gas emission measuring device for rice fertilization that can automatically travel in the rice paddy area and get close to the rice to measure its content.

[0005] The technical solution of this invention is: a greenhouse gas emission measuring device for rice fertilizer reduction, comprising a measuring instrument, a display screen, a gas receiving pipe, and a floating mechanism. The measuring instrument has a display screen on its upper left side and a gas receiving pipe on its left side. The measuring instrument is mounted on the floating mechanism, which includes a floating plate, limiting frames, connecting frames, a bidirectional motor, transmission components, a motor bracket, and drive blades. Four limiting frames are provided at the top of the floating plate, and these frames are slidably connected to the measuring instrument. Connecting frames are provided at the four corners of the bottom of the floating plate, and drive blades are rotatably mounted on each connecting frame. The drive blades on the right side are interconnected. A motor bracket is provided on the lower left side of the floating plate, and a bidirectional motor is mounted on the motor bracket. The output shafts of the bidirectional motors are connected to adjacent drive blades. Two symmetrical transmission components are provided between the drive blades.

[0006] Furthermore, it also includes a mud-breaking mechanism, which includes a rotating connecting plate, mud-breaking plates, pins, and mud-breaking toothed plates. A rotating connecting plate is rotatably installed on the left side of the floating plate, and mud-breaking plates are rotatably installed on both the front and rear sides of the rotating connecting plate. A pin is slidably installed between the left sides of the mud-breaking plates, and three mud-breaking toothed plates are installed on the outer side of each mud-breaking plate.

[0007] Furthermore, it also includes a support mechanism, which includes a support plate, guide rods, a first spring, a fixed plate, a locking element, and a second spring. Two guide rods are symmetrically arranged on the upper sides of both the left and right sides of the floating plate. A support plate is slidably arranged between the adjacent guide rods. Two first springs are symmetrically arranged between the support plate and the floating plate. A fixed plate is arranged on the upper sides of both the left and right sides of the floating plate. A locking element is slidably arranged on the fixed plate. A second spring is arranged between the locking element and the adjacent fixed plate.

[0008] Furthermore, it also includes a mud-blocking mechanism, which includes a mud-blocking plate, a torsion spring, a first pulley assembly, a cam, a second pulley assembly, and a bevel gear set. Mud-blocking plates are rotatably installed on the lower sides of both the front and rear parts of the floating plate. Two torsion springs are symmetrically installed between the mud-blocking plates and the floating plate. Cams are rotatably installed on the lower sides of both the front and rear parts of the floating plate. A first pulley assembly is installed between the cams and the floating plate. A second pulley assembly is installed between the first pulley assembly and the floating plate. A bevel gear set is installed between the drive fan blade on the right side and the second pulley assembly.

[0009] Furthermore, it also includes a mud removal mechanism, which includes a guide support, a sliding frame, and rubber blocks. A guide support is provided on the top of each mud-breaking plate, and a sliding frame is slidably and rotatably installed on each guide support. Three rubber blocks are provided on the inner side of each sliding frame.

[0010] Furthermore, it also includes a traction mechanism, which includes a fixed seat and a traction ring. The top of the support plate is provided with a fixed seat, and the top of the fixed seat is provided with a traction ring.

[0011] Furthermore, the transmission assembly includes a transmission wheel and a transmission belt. Each drive fan blade is equipped with a transmission wheel, and a transmission belt is wound between two symmetrical transmission wheels on the left and right sides.

[0012] Furthermore, the mud-breaking plate and the rotating connecting plate form a triangular structure.

[0013] Furthermore, the first pulley assembly includes a first pulley, a second pulley, and a first belt. The first pulley is rotatably mounted on the bottom of the floating plate, and the second pulley is mounted on each cam. The first belt is wound between the first pulley and the second pulley.

[0014] Furthermore, the second pulley assembly includes a third pulley, a fourth pulley, and a second belt. The third pulley is provided on the first pulley assembly, and the fourth pulley is rotatably provided on the lower right side of the float plate. The second belt is wound between the third pulley and the fourth pulley.

[0015] The beneficial effects are as follows: 1. The present invention drives the corresponding drive fan blades to rotate through the front and rear output shafts of the bidirectional motor, thereby enabling the right drive fan blades to rotate synchronously under the drive of the transmission component, so that the floating plate can drive the measuring instrument to move automatically in the paddy field, thereby detecting the greenhouse gas content in the paddy field, improving the convenience of detection, and making the detection data more accurate.

[0016] 2. The present invention connects the left side of the mud-breaking plate with a pin, so that the left side of the mud-breaking plate forms a conical inclined structure, thereby cutting and breaking up the mud in the direction of the floating plate's movement and reducing the resistance during the floating plate's movement.

[0017] 3. The present invention supports the device when it needs to be placed on the ground, preventing the drive fan blades from contacting the ground and causing damage. When the device needs to move automatically in water, the locking device is pulled to release the locking of the support plate, so that the support plate slides upward under the action of the first spring and shields the left and right sides of the measuring instrument.

[0018] 4. The present invention drives the fan blade to rotate the bevel gear set, which in turn drives the second pulley assembly to rotate the first pulley assembly. This causes the cam to rotate continuously and intermittently push the mudguard during the rotation, causing the mudguard to swing continuously and push the surrounding mud and water outward, thus preventing the mud from affecting the normal operation of the device.

Detailed Implementation

[0029] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] A device for measuring greenhouse gas emissions from rice cultivation using fertilizer reduction techniques, such as... Figure 1 and Figure 2 As shown, it includes a measuring instrument 1, a display screen 2, a gas receiving tube 3, and a floating mechanism 4. The upper left side of the measuring instrument 1 is connected to the display screen 2 for displaying gas emission data, and the left side of the measuring instrument 1 is connected to the gas receiving tube 3 for receiving gas. The measuring instrument 1 is mounted on the floating mechanism 4, which can float in the paddy field and move automatically.

[0031] It should be noted that when carrying out rice fertilizer reduction operations, it is necessary to detect the greenhouse gas emission content in the paddy field. This device can be used for detection and processing. First, place this device in the paddy field, then activate the floating mechanism 4, so that the measuring instrument 1 can move freely on the water surface in the paddy field and collect the gas in the paddy field through the gas receiving pipe 3. Then the greenhouse gas emission content will be directly displayed on the display screen 2, which makes it easy for the detection personnel to quickly read the data.

[0032] like Figure 1 , Figure 3 and Figure 4As shown, the floating mechanism 4 includes a floating plate 41, a limiting frame 42, a connecting frame 43, a bidirectional motor 44, a transmission assembly 45, a motor bracket 46, and a drive fan blade 47. The top of the floating plate 41 is bolted with four limiting frames 42 for limiting the measuring instrument 1. The limiting frames 42 are slidably connected to the measuring instrument 1. The bottom four corners of the floating plate 41 are bolted with connecting frames 43. The drive fan blades 47 are rotatably connected to the connecting frames 43. The drive fan blades 47 on the right side are interconnected. The lower left side of the floating plate 41 is bolted with a motor bracket 46. The bidirectional motor 44 is connected to the motor bracket 46. The output shaft of the bidirectional motor 44 is arranged in a front-back orientation. The output shaft of the bidirectional motor 44 is connected to the adjacent drive fan blade 47. The drive fan blades 47 are connected with two symmetrical transmission assemblies 45. The transmission assembly 45 includes a transmission wheel and a transmission belt. The drive fan blades 47 are connected with transmission wheels. The two symmetrical transmission wheels are wound with a transmission belt.

[0033] It should be noted that, to facilitate greenhouse gas content detection in paddy fields, the measuring instrument 1 can be pushed in from the right side of the limiting frame 42, locking it in place. Then, the floating plate 41 is placed on the water surface of the paddy field, allowing the device to float completely. Next, the dual-axis motor is started, with both its front and rear output shafts driving the corresponding drive blades 47 to rotate. This, in turn, causes the right-side drive blade 47 to rotate synchronously under the drive of the transmission component 45. This allows the floating plate 41 to propel the measuring instrument 1 freely within the paddy field. After detection, the bidirectional motor 44 is turned off. In summary, by using the front and rear output shafts of the bidirectional motor 44 to drive the corresponding drive blades 47, which in turn cause the right-side drive blade 47 to rotate synchronously under the drive of the transmission component 45, the floating plate 41 can propel the measuring instrument 1 automatically within the paddy field. This allows for greenhouse gas content detection at multiple locations within the paddy field, improving detection convenience and ensuring more accurate data.

[0034] like Figure 1 and Figure 5 As shown, it also includes a mud-breaking mechanism 5, which includes a rotating connecting plate 51, a mud-breaking plate 52, a pin 53, and a mud-breaking toothed plate 54. The left side of the floating plate 41 is rotatably connected to the rotating connecting plate 51. Both the front and rear sides of the rotating connecting plate 51 are rotatably connected to mud-breaking plates 52 for breaking the mud in the paddy field. The left sides of the mud-breaking plates 52 are slidably connected to the pin 53, which allows the two mud-breaking plates 52 to be connected. The mud-breaking plates 52 and the rotating connecting plate 51 form a triangular structure, which has strong stability. Three mud-breaking toothed plates 54 for assisting in breaking the mud are connected to the outer side of the mud-breaking plates 52.

[0035] It should be noted that when the floating plate 41 moves automatically in the paddy field, in order to reduce the resistance of the paddy field soil to the floating plate 41, the mud-breaking plate 52 and the mud-breaking toothed plate 54 cooperate to cut and break the soil in the direction of the floating plate 41's movement. Since the mud-breaking plates 52 are connected by pins 53, the left side of the mud-breaking plates 52 has an inclined structure, which can reduce the resistance that the floating plate 41 may encounter during its movement and prevent the mud resistance from causing the floating plate 41 to change direction, thus affecting the collection of greenhouse gases by the gas receiving pipe 3. In summary, by connecting the left side of the mud-breaking plates 52 with pins 53, the left side of the mud-breaking plates 52 has a conical inclined structure, which cuts and breaks the soil in the direction of the floating plate 41's movement, reducing the resistance of the floating plate 41 during its movement.

[0036] like Figure 1 and Figure 6 As shown, it also includes a support mechanism 6, which includes a support plate 61, guide rods 62, first springs 63, fixing plates 64, locking elements 65, and second springs 66. The upper sides of the left and right sides of the floating plate 41 are each connected to two symmetrical guide rods 62. The support plate 61 for supporting the floating plate 41 is slidably connected between the adjacent guide rods 62. The support plate 61 and the floating plate 41 are each connected to two symmetrical first springs 63. The first springs 63 are all wound around the adjacent guide rods 62. The upper sides of the left and right sides of the floating plate 41 are each connected to a fixing plate 64 by bolts. The fixing plate 64 is each slidably connected to a locking element 65 for locking and limiting the adjacent support plate 61. The locking element 65 and the adjacent fixing plate 64 are each connected to a second spring 66. The second springs 66 are all wound around the adjacent fixing plate 64.

[0037] It should be noted that when the device is not used in the paddy field, the support plate 61 can directly contact the ground to support the device and prevent the drive fan blade 47 from directly contacting the ground and causing damage. When the device is placed in the water of the paddy field, in order to prevent the support plate 61 from affecting the movement, the locking parts 65 need to be pulled away from the measuring instrument 1. This causes the second spring 66 to be stretched, and the support plate 61 is no longer locked. Initially, the first spring 63 is in a compressed state. Therefore, as the support plate 61 is no longer locked, it will slide upward under the action of the first spring 63, blocking the left and right sides of the measuring instrument 1 and preventing water from flowing into the measuring instrument 1 during the operation of the drive fan blade 47. If water damage occurs, release the locking member 65 so that each locking member 65 slides back to its original position under the action of the corresponding second spring 66. Similarly, when the device needs to be placed on the ground after use, first pull each locking member 65 to the side away from each other, then push each support plate 61 downward to reset it, so that the first spring 63 returns to its compressed state. Finally, release the locking member 65 so that each support plate 61 is locked and fixed by the adjacent locking member 65. In summary, the support plate 61 supports the device when it needs to be placed on the ground, preventing the drive fan blade 47 from contacting the ground and causing damage. When the device needs to move automatically in the water, pull the locking member 65 to release the locking and fixing of the support plate 61, so that the support plate 61 slides upward under the action of the first spring 63 and shields the left and right sides of the measuring instrument 1.

[0038] like Figure 1 and Figure 7As shown, it also includes a mud-blocking mechanism 7, which includes a mud-blocking plate 71, a torsion spring 72, a first pulley assembly 73, a cam 74, a second pulley assembly 75, and a bevel gear set 76. Mud-blocking plates 71 for blocking silt on both sides are rotatably connected to the lower front and rear parts of the floating plate 41. Two symmetrical torsion springs 72 are connected between the mud-blocking plates 71 and the floating plate 41, and the torsion springs 72 are wound around the mud-blocking plates 71. Cams 74 for pushing adjacent mud-blocking plates 71 are rotatably connected to the lower front and rear parts of the floating plate 41. The cams 74 are located inside the mud-blocking plates 71. A first pulley assembly 73 is connected between the cams 74 and the floating plate 41. The first pulley assembly 73 includes a first pulley, a second pulley, and a first belt. The bottom of the floating plate 41 rotates. A first pulley is connected to the cam 74, and a second pulley is connected to each cam 74. A first belt is wound between the first pulley and the second pulley. A second pulley assembly 75 is connected between the first pulley assembly 73 and the floating plate 41. The second pulley assembly 75 includes a third pulley, a fourth pulley, and a second belt. The third pulley is connected to the first pulley assembly 73. A fourth pulley is rotatably connected to the lower right side of the floating plate 41. A second belt is wound between the third pulley and the fourth pulley. A bevel gear set 76 is connected between the right-side drive fan blade 47 and the second pulley assembly 75. The bevel gear set 76 consists of two bevel gears meshing together. One bevel gear is connected between the right-side drive fan blade 47, and the other bevel gear is connected to the second pulley assembly 75. The bevel gears mesh with each other.

[0039] It should be noted that as the bidirectional motor 44 drives the drive fan blades 47 to rotate, the right drive fan blade 47 drives the bevel gear set 76 to rotate, thereby causing the second pulley assembly 75 to rotate. The second pulley assembly 75 drives the first pulley assembly 73 to rotate, which in turn causes the cams 74 to rotate synchronously. As the cams 74 start to rotate, the protruding parts of the cams 74 push the adjacent mudguards 71, causing the mudguards 71 ​​to rotate to the side away from each other. The torsion springs 72 are deformed by force. At this time, the mudguards 71 ​​push the silt on the front and rear sides of the floating plate 41 outward, preventing the silt from accumulating and obstructing the floating plate 41, and also preventing the silt from affecting the normal operation of the drive fan blades 47. When the cam 74 stops pressing the mudguard 71, the mudguard 71 will rotate inward and reset under the action of the corresponding torsion spring 72. That is, as the cam 74 rotates continuously, the mudguard 71 will swing continuously, thereby pushing the surrounding mud and water outward and preventing the silt from affecting the normal operation of the device. After the greenhouse gas content detection is completed, the bidirectional motor 44 can be turned off. In summary, by driving the fan blade 47 to drive the bevel gear set 76 to rotate, the second pulley assembly 75 drives the first pulley assembly 73 to rotate, thereby making the cam 74 rotate continuously and intermittently push the mudguard 71 during the rotation, causing the mudguard 71 to swing continuously, thereby pushing the surrounding mud and water outward and preventing the silt from affecting the normal operation of the device.

[0040] like Figure 1 and Figure 8 As shown, it also includes a mud removal mechanism 8, which includes a guide bracket 81, a sliding frame 82 and rubber blocks 83. The top of the mud breaking plate 52 is connected to the guide bracket 81, and the sliding frame 82 is slidably and rotatably connected to the guide bracket 81. Three rubber blocks 83 for removing mud from the inside of the mud breaking tooth plate 54 are connected to the inner side of the sliding frame 82.

[0041] It should be noted that, during greenhouse gas content testing, in order to prevent the rubber blocks 83 from obstructing the soil, the sliding frame 82 needs to be flipped upwards. After the test is completed, the sliding frame 82 is flipped downwards to reset, so that the rubber blocks 83 are engaged with the corresponding mud-breaking toothed plates 54. Then, the sliding frame 82 is pushed to the left, so that the rubber blocks 83 move to the left, thereby pushing out the soil remaining in the mud-breaking toothed plates 54, preventing soil from remaining in the mud-breaking toothed plates 54 and affecting subsequent use.

[0042] like Figure 1 and Figure 9 As shown, it also includes a traction mechanism 9, which includes a fixed seat 91 and a traction ring 92. The top of the support plate 61 is connected to the fixed seat 91, and the top of the fixed seat 91 is connected to the traction ring 92, which facilitates the operator to retrieve the device.

[0043] It should be noted that during routine handling of this device, it can be directly held by the traction ring 92, making it easy to move. At the same time, when the floating plate 41 is obstructed in the paddy field and cannot continue to move, the inspection personnel need to retrieve the device for inspection. In this case, the device can be pulled back directly by hooking the traction ring 92 with a tool.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
