Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to an intelligent rice seedling bed leveler and a use method thereof. Background Art

[0002] The rice seedling bed is an important part of rice production. The quality of the seedling bed directly affects the growth of rice seedlings and the success rate of later transplanting. The operation of the rice tray pre-bed requires the six-character standard of "flat, straight, clean, neat, broken, and solid". However, to achieve these standards in a short period of time, the requirements for the bed are quite high, especially to achieve the ideal state of "solid on top and loose on the bottom", and to ensure that the looseness is moderate and consistent, which poses a high challenge to traditional mechanized equipment. At present, most areas still rely on manpower for repeated seedling bed preparation operations. For example, in a standard rice seedling shed, at least 2 workers are required to complete the preparation of the seedling bed after 3 to 5 days of repeated labor, which is time-consuming and labor-intensive, and affects the efficiency and quality of seedling cultivation.

[0003] At present, although some areas have begun to use mechanical equipment for land leveling operations to replace some manual operations, the technical level of existing mechanical equipment is still insufficient.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0043] like Figures 1 to 12As shown, the intelligent rice seedling bed leveler includes: a frame 1, a mounting frame 2, a humidity sensor 3 and a leveling mechanism 4. The frame 1 is connected to the mounting frame 2 by rotation. The mounting frame 2 is provided with two rollers 21 and a direction adjustment handle 22. The direction adjustment handle 22 is fixedly connected to the mounting frame 2 and is used to adjust the walking direction of the leveler. The humidity sensor 3 is fixed on the mounting frame 2 and is specifically used to detect the humidity condition of the seedling bed soil. Figure 1 , Figure 2 and Figure 3 As shown, in order to ensure the accuracy of humidity detection, the lower end of the probe (not shown) of the humidity sensor 3 is lower than the lower part of the roller 21 so that the probe can be fully inserted into the soil of the seedbed to obtain soil humidity information in real time.

[0044] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the leveling mechanism 4 includes a roller 41, a transmission shaft 42, a vibration mechanism 43 and a first driving mechanism 44. The internal structure of the roller 41 is complex, specifically including two inner mounting plates 411 and two outer mounting plates 412. The two outer mounting plates 412 are fixedly connected to the inner wall of the roller 41, and the two inner mounting plates 411 are also fixedly connected to the inner wall of the roller 41, and the two inner mounting plates 411 are located between the outer mounting plates 412, and a mounting cavity 413 is formed between the two inner mounting plates 411. The vibration mechanism 43 is installed in the mounting cavity 413 to provide vibration force. The transmission shaft 42 passes through the roller 41, and is fixedly connected to the two outer mounting plates 412, and is supported by the frame 1 by a rotational connection. The first driving mechanism 44 is installed on the frame 1, and drives the rotation of the roller 41 through the transmission shaft 42.

[0045] In actual work, the first driving mechanism 44 drives the outer mounting plate 412 to rotate by driving the transmission shaft 42, and then drives the roller 41 to rotate, thereby completing the task of leveling the ground. At the same time, the rotation of the transmission shaft 42 also drives the frame 1 and the mounting frame 2 to move on the ground, and the roller 21 rolls on the ground to ensure that the grader can move forward smoothly. The operator adjusts the direction of the grader by controlling the direction adjustment handle 22 to ensure the flatness and consistency of the seedbed.

[0046] The vibration mechanism 43 automatically adjusts the vibration intensity according to the soil moisture information detected by the humidity sensor 3. This intelligent adjustment function of the vibration mechanism 43 solves the problem that the existing grader cannot adjust the vibration force according to the change of soil moisture during operation. When the soil moisture is high, the vibration mechanism 43 will reduce the vibration force to avoid excessive vibration force causing soil caking or excessive compaction, which affects the quality of the rice seedling bed; when the soil moisture is low, the vibration mechanism 43 will increase the vibration force to ensure the compaction effect and moderate looseness of the seedling bed.

[0047] When the soil humidity is high, if the vibration intensity of the vibration mechanism 43 is too large, the soil may be over-compacted, resulting in the destruction of the soil structure, affecting the air permeability and drainage of the seedling root system, which is not conducive to the normal growth of the seedling. The soil humidity is detected by the humidity sensor 3, and the intelligent rice seedling bed leveler can automatically reduce the vibration intensity of the vibration mechanism 43 to ensure that the soil is moderately loose, protect the structural properties of the seedling bed soil, and be conducive to the rooting and development of the rice seedlings. When the soil humidity is low, the soil is loose and cannot be effectively compacted. When the humidity sensor 3 detects that the soil is dry, the vibration mechanism 43 will automatically increase the vibration intensity to ensure that the dry soil can be fully compacted. In this way, it can ensure that the upper soil of the seedling bed is soft and conducive to the growth of the seedlings, and at the same time, it can also make the lower soil solid and stable, meeting the requirements of "solid on top and loose on the bottom".

[0048] Specifically, the direction adjustment handle 22 includes a connecting column 221, two operating arms 222 and two grips 223; the two operating arms 222 are respectively fixedly connected to the connecting column 221, and the two grips 223 are respectively installed at one end of the operating arm 222 away from the connecting column 221, so that the operator can manually hold and adjust the direction. The mounting frame 2 is provided with a connecting portion 23, and the connecting column 221 is fixedly connected to the connecting portion 23 by passing through the connecting portion 23, so as to ensure that the direction adjustment handle 22 is firmly installed on the mounting frame 2. In order to realize the direction adjustment of the grader, a mounting seat 11 is also provided on the frame body 1, and the mounting seat 11 and the connecting portion 23 are connected by rotation to realize linkage control. Specifically, an installation space is provided in the mounting seat 11, and the lower end of the connecting portion 23 is inserted into the installation space and closely matches with the mounting seat 11 to ensure the smooth operation of the direction adjustment system.

[0049] In order to further enhance the stability of the connecting column 221 during rotation, a sleeve 12 is provided on the mounting seat 11, and the lower end of the connecting column 221 is rotatably connected to the bottom wall of the mounting space in the mounting seat 11 through the sleeve 12. The design of the sleeve 12 can improve the stability of the connecting column 221 during rotation.

[0050] During operation, the operator holds the handle 223 with both hands and moves the handle 223. The handle 223 drives the connecting column 221 to rotate through the operating arm 222. The connecting column 221 directly drives the mounting frame 2 to rotate. The mounting frame 2 changes the travel direction of the two rollers 21, thereby realizing the adjustment of the travel direction of the grader.

[0051] Specifically, the first driving mechanism 44 includes a first motor 441, a first active pulley 442, a first driven pulley 443 and a first transmission belt 444; the first motor 441 is fixedly connected to the frame 1, the first active pulley 442 is connected to the output end of the first motor 441, the first driven pulley 443 is fixedly connected to the transmission shaft 42, and the first transmission belt 444 is connected between the first active pulley 442 and the first driven pulley 443. When the first motor 441 is started, the output end of the first motor 441 drives the first active pulley 442 to rotate, the first active pulley 442 drives the first driven pulley 443 to rotate through the first transmission belt 444, and the first driven pulley 443 drives the transmission shaft 42 to rotate, thereby realizing the driving of the transmission shaft 42.

[0052] The vibration mechanism 43 in the intelligent rice seedling bed leveler specifically includes: a tube body 431, two second active pulleys 432, two second driven pulleys 433, two rotating shafts 434, two first cams 435, two second cams 436, two second transmission belts 437, a control component 438 and a second driving mechanism 439.

[0053] The tube body 431 is installed between the two inner mounting plates 411 by a rotational connection, and can achieve stable rotation. The second driving mechanism 439 is connected to the tube body 431, and is used to drive the rotation of the tube body 431. When the second driving mechanism 439 is started, the tube body 431 is driven to rotate along its axial direction, and the rotation of the tube body 431 simultaneously drives the two second driving pulleys 432 to rotate, and the two second driving pulleys 432 are connected to the two second driven pulleys 433 through the second transmission belt 437, thereby driving the second driven pulleys 433 to rotate synchronously.

[0054] The two rotating shafts 434 are respectively installed between the two inner mounting plates 411, and the two second driven pulleys 433 are respectively fixedly connected to the two rotating shafts 434, and the axes of the two rotating shafts 434 are in the same plane as the axis of the tube body 431. A first cam 435 is fixed on each rotating shaft 434, and the first cam 435 is driven to rotate synchronously by the rotation of the rotating shaft 434. The two rotating shafts 434 are respectively fixedly connected to the first cam 435 through the first spline 4341 thereon, thereby ensuring that the first cam 435 realizes synchronous rotational motion during the rotation of the rotating shaft 434.

[0055] In addition, the two second cams 436 are respectively mounted on the two rotating shafts 434 and are rotationally connected to the rotating shafts 434 through the second splines 4361. Since there is a certain rotational connection between the second cams 436 and the rotating shaft 434, when the rotating shaft 434 rotates, the second cams 436 can generate corresponding vibrations under the action of the rotating shaft 434.

[0056] When the second driving mechanism 439 is started and drives the tube body 431 to rotate, the rotation of the tube body 431 transmits power to the rotating shaft 434 through the second driving pulley 432, the second transmission belt 437 and the second driven pulley 433. The rotation of the rotating shaft 434 drives the first cam 435 to rotate, and the rotation of the first cam 435 causes the rotating shaft 434 to vibrate periodically. The vibration force of the rotating shaft 434 is transmitted to the roller 41 through the inner mounting plate 411, and finally the roller 41 vibrates, and the vibration force is transmitted to the ground to compact and level the seedbed.

[0057] like Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the control component 438 in the present invention is used to adjust the vibration intensity of the vibration mechanism 43, and mainly includes a cylinder 4381, a driving member 4382 and a connecting sleeve 4383.

[0058] The connecting sleeve 4383 passes through the driving member 4382 and is rotatably connected to the driving member 4382 to achieve flexibility in power transmission. The connecting sleeve 4383 can slide on the first spline 4341 and the second spline 4361 to switch between different vibration force states.

[0059] The cylinder 4381 is fixed on the inner wall of the roller 41 to ensure that its output end can be effectively connected to the driving member 4382 to provide reliable driving force.

[0060] The inner wall of the connecting sleeve 4383 is provided with an inner spline 4384, and the end of the inner spline 4384 is also provided with a guide slope 43841 for achieving smooth engagement. The connecting sleeve 4383 can engage with the first spline 4341 and the second spline 4361 respectively and slide thereon when necessary.

[0061] When the output end of the cylinder 4381 is in the extended state, the internal spline 4384 of the connecting sleeve 4383 is meshed with the first spline 4341. At this time, the rotation of the rotating shaft 434 drives the first spline 4341 to rotate, thereby driving the connecting sleeve 4383 to rotate. Since the second cam 436 is rotationally connected through the rotating shaft 434 but is not driven, there is a lack of additional vibration force from the second cam 436 at this time, and the equipment is in a state of lower vibration force, which is suitable for working environments that require lighter vibration force.

[0062] When the vibration force needs to be increased, the output end of the cylinder 4381 pulls the connecting sleeve 4383 inward through the driving member 4382. The inner spline 4384 on the connecting sleeve 4383 engages with the second spline 4361 through the guiding inclined surface 43841 to ensure smooth switching. At this time, the connecting sleeve 4383 engages with the first spline 4341 and the second spline 4361 at the same time, and the rotation of the first spline 4341 further drives the second spline 4361 to rotate through the connecting sleeve 4383. Since the second spline 4361 is fixedly connected to the second cam 436, the rotation of the second cam 436 further increases the vibration force, thereby significantly increasing the vibration force of the roller 41 and meeting the high vibration force required for soil compaction and leveling.

[0063] By controlling the extension and contraction of the cylinder 4381, the control component 438 can flexibly adjust the vibration force of the vibration mechanism 43. In the low vibration force state, the device is suitable for operation scenarios where the soil is relatively moist or requires light pressure; in the high vibration force state, through the participation of the second cam 436, the device can provide a strong vibration force for compacting relatively dry or loose soil. This design realizes the dynamic adjustment of the vibration force, allowing the device to adapt to different soil conditions and improve the operating efficiency and effect of the grader.

[0064] In the specific implementation of the present invention, the vibration intensity of the vibration mechanism 43 can be flexibly adjusted according to actual needs. In order to meet the diverse requirements of vibration force under different working conditions, multiple first cams 435 and second cams 436 can be designed. In this embodiment, four control components 438 are designed, and each control component 438 corresponds to a second cam 436, so as to achieve more vibration force adjustment functions.

[0065] like Fig.13 As shown, the system also includes a controller, and the humidity sensor 3 is connected to the control component 438 through the controller. The humidity sensor 3 is used to detect soil moisture in real time, and convert the acquired humidity data into an electrical signal and transmit it to the controller. The controller automatically controls each control component 438 based on the current soil moisture, thereby determining whether the second cam 436 rotates with the rotating shaft 434.

[0066] Specifically, the controller adjusts the vibration intensity according to the soil moisture detected by the moisture sensor 3:

[0067] When the humidity is low: When the soil humidity is low and the soil is relatively dry, it is required to increase the vibration intensity to ensure the compaction effect. At this time, the controller controls the component 438 to make the second cam 436 rotate with the rotating shaft 434 to increase the vibration intensity of the system. Each additional second cam 436 that rotates with the rotating shaft 434 will increase the vibration intensity accordingly.

[0068] When the humidity is moderate or high: If the soil humidity is high or has reached an ideal compaction state, the controller can stop part or all of the second cams 436 from following the rotation of the rotating shaft 434 through the control assembly 438. In this way, the vibration intensity will be appropriately weakened to avoid excessive compaction or caking of the soil, thereby keeping the seedbed loose and moderate.

[0069] During the operation of the grader, as the roller 41 rotates, the two shafts 434 not only perform circular motion around the transmission shaft 42, but also vibrate themselves. This design ensures uniform distribution of vibration force, effectively balances the operation of the vibration system, and improves the stability and smoothness of the operation.

[0070] The intelligent rice seedling bed leveler of the present invention can automatically adjust the vibration intensity according to the soil moisture without manual adjustment. The soil moisture is detected in real time by the humidity sensor 3, and the detection data is transmitted to the controller. The controller intelligently controls the control component 438 according to different humidity to make the second cam 436 rotate with the rotating shaft 434, thereby realizing automatic adjustment of the vibration intensity. When the soil moisture is low, the controller instructs multiple second cams 436 to participate in the work and increase the vibration force; when the humidity is high, the participation of the second cam 436 is reduced to reduce the vibration force and ensure that the soil reaches a loose and moderate state. In addition, the cylinder 4381 accurately controls the meshing process of the cam by controlling the sliding of the connecting sleeve 4383, so that the entire vibration mechanism 43 can be dynamically adjusted according to the real-time soil conditions, thereby improving the working efficiency and effect. This intelligent design reduces manual operation and ensures the high efficiency and accuracy of the leveling operation.

[0071] like Fig.11 As shown, the second driving mechanism 439 specifically includes: a second motor 4391, a driving bevel gear 4392 and a driven bevel gear 4393. The second motor 4391 is fixedly mounted on the inner wall of the roller 41 to ensure its stability. The driving bevel gear 4392 is mounted on the output end of the second motor 4391 and meshedly connected with the driven bevel gear 4393, and the driven bevel gear 4393 is fixedly connected to the tube body 431.

[0072] During operation, after the second motor 4391 is started, the output end of the second motor 4391 drives the active bevel gear 4392 to rotate. The rotation of the active bevel gear 4392 drives the driven bevel gear 4393 to rotate synchronously, and the rotation of the driven bevel gear 4393 further drives the tube body 431 to rotate, thereby effectively driving the tube body 431. This design ensures that power is smoothly and efficiently transmitted from the second motor 4391 to the tube body 431 through gear transmission, thereby driving the tube body 431.

[0073] Specifically, the intelligent rice seedling bed leveler also includes a battery 5, which is arranged on the frame 1. The battery 5 is used to power the leveling mechanism 4, provide stable power support, and ensure that the equipment can continue to work in different environments. The design of the battery 5 enables the leveler to achieve mobile operation without the need for external power connection, further improving the operation flexibility and efficiency, and is particularly suitable for mechanized operation of large-area seedling beds.

[0074] Specifically, the intelligent rice seedling bed leveler also includes a seat 6, which is arranged on the frame 1. The arrangement of the seat 6 improves the comfort of the operator, making long-term operation easier and more efficient. At the same time, the operator can flexibly control the walking direction of the leveler directly through the direction adjustment handle 22 on the seat 6, thereby improving the operation accuracy during the operation process.

[0075] Specifically, a scraper 24 is provided on the mounting frame 2, and the scraper 24 is inclined, close to the roller 21, and located on the side of the roller 21 close to the leveling mechanism 4. When the leveler is moving in the seedbed, some soil will inevitably adhere to the roller 21, and as the soil accumulates, the rotation of the roller 21 may be affected. To solve this problem, the design of the scraper 24 ensures that the soil contacts the scraper 24 every time the roller 21 rotates, and the scraper 24 can scrape off the attachments on the roller 21 in time, keep the roller 21 clean, and ensure the smoothness and working efficiency of the leveler during the moving process.

[0076] Specifically, if Fig.12 As shown, the intelligent rice seedling bed leveler of the present invention further includes a cleaning component 7, which is used to automatically clean the soil attached to the roller 41 to ensure the continuity and efficiency of the leveling operation. The structure of the cleaning component 7 specifically includes a roller brush 71, a third driving pulley 72, a third driven pulley 73 and a third transmission belt 74.

[0077] The roller brush 71 is rotatably mounted on the frame 1, and its bristles are in contact with the outer wall of the roller 41 to remove the dirt attached to the roller 41. The design of the roller brush 71 ensures that the dirt will not accumulate on the roller 41 for a long time, thereby avoiding affecting the normal operation of the grader.

[0078] The third driving pulley 72 is connected to the transmission shaft 42, and when the transmission shaft 42 rotates, the third driving pulley 72 rotates synchronously. Through the connection of the third transmission belt 74, the third driving pulley 72 drives the third driven pulley 73 to rotate, thereby driving the roller brush shaft 711 to rotate, so that the roller brush 71 rotates accordingly.

[0079] During the operation of the grader, when the transmission shaft 42 drives the roller 41 to rotate, the dirt will adhere to the outer wall of the roller 41. At this time, the rotation of the transmission shaft 42 simultaneously drives the third driving pulley 72 to rotate, and the third driving pulley 72 drives the third driven pulley 73 and the roller brush shaft 711 to rotate synchronously through the third transmission belt 74, and finally drives the roller brush 71 to rotate. The bristles of the roller brush 71 contact the roller 41, and the dirt on the outer wall of the roller 41 is cleaned by the rotation of the bristles.

[0080] like Figure 3 As shown, the roller brush 71 is positioned close to the roller 41 to ensure that the cleaned soil will not fall directly, but will be flattened and processed again along the direction of travel of the roller 41. The advantage of this design is that the cleaned soil can continue to participate in the leveling operation, ensuring the rational use of the soil and further improving the working efficiency of the grader. The cleaning component 7 is exquisitely designed, using the power of the transmission shaft 42, through the transmission of the third active pulley 72, the third transmission belt 74 and the third driven pulley 73, to achieve the automatic cleaning function of the roller 41, ensuring that the roller 41 is always in a clean state during the operation, avoiding the accumulation of soil and affecting the operation efficiency. In addition, the cleaned soil can continue to be processed by the roller 41, reducing the waste of soil and the trouble of repeated processing, and further improving the quality and efficiency of the operation.

[0081] In addition, another embodiment of the present invention further provides a method for using an intelligent rice seedling bed leveler, comprising:

[0082] Seedbed preparation: Place the intelligent rice seedbed leveler on the rice seedling bed to be operated, ensure that the frame 1 of the equipment is parallel to the surface of the seedbed, check that the battery 5 is sufficiently charged, and confirm that all connectors, controllers, humidity sensors 3 and leveling mechanisms 4 are in normal working condition.

[0083] Humidity detection: Start the humidity sensor 3 to detect the humidity of the seedbed soil in real time, and transmit the humidity data to the controller in the form of an electrical signal. The controller adjusts the working state of the vibration mechanism 43 according to the humidity information.

[0084] Vibration force adjustment: The vibration mechanism 43 automatically adjusts the vibration force according to the soil moisture information detected by the moisture sensor 3.

[0085] In this embodiment, a soil moisture threshold can be set, for example, the moisture threshold is 75%; when the soil moisture is detected to be lower than or equal to the moisture threshold of 75%, the vibration mechanism 43 increases the vibration intensity to ensure the soil compaction effect; when the soil moisture is detected to be higher than the moisture threshold of 75%, the vibration mechanism 43 reduces the vibration intensity to prevent excessive compaction of the soil and maintain the appropriate looseness of the seedbed.

[0086] More specifically, the controller intelligently controls the operating state of the control component 438 according to the soil moisture information transmitted by the humidity sensor 3, thereby adjusting the vibration intensity of the vibration mechanism 43. When the soil moisture is low, the control component 438 drives the second cam 436 to rotate synchronously with the rotating shaft 434 to enhance the vibration force; and when the soil moisture is high, the control component 438 stops the rotation connection of the second cam 436, thereby weakening the vibration force. Through this adjustment mechanism, it is ensured that the seedbed can achieve the ideal looseness and moderateness under different humidity conditions, providing a suitable planting environment.

[0087] Leveling operation: Start the leveling mechanism 4, drive the roller 41 to rotate through the transmission shaft 42, and the vibration mechanism 43 performs vibration compaction and leveling operation on the soil through the roller 41. The operator controls the direction adjustment handle 22 through the seat 6 to guide the leveler to move along the surface of the seedbed.

[0088] During the leveling operation, the roller brush 71 of the cleaning assembly 7 is driven by the transmission shaft 42 to automatically clean the soil attached to the outer wall of the roller 41 to ensure that the roller 41 remains clean. The cleaned soil is compacted and leveled again by the roller 41 to prevent soil accumulation from affecting the operation effect.

[0089] After the operation is completed, turn off the power supply of the equipment, check and maintain the humidity sensor 3, the vibration mechanism 43, the leveling mechanism 4 and the cleaning assembly 7 to ensure that the equipment is in good condition and ready for the next use.

[0090] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
