Description

Technical Field

[0001] The present invention relates to the technical field of intelligent agricultural power machinery, and in particular to an integrated film covering and transplanting device for rice planting. Background Art

[0002] The intelligent rice mulching and transplanting machine represents a significant breakthrough in modern agricultural technology. Combining mechanical engineering, materials science, and intelligent sensor technology, it enables precise coordination between mulching and transplanting, significantly improving both the efficiency and ecological benefits of rice cultivation.

[0003] In the prior art, to reduce the resistance of seedling needles to soil penetration, integrated mulching and transplanting machines usually control the seedling needles to be inserted into the soil at an angle. During the inclined insertion process, the seedling needles pierce the mulch film at an acute angle, thereby ensuring the integrity of the mulch film to the greatest extent. However, this approach has the following disadvantages: In the process of pulling the seedling needles out of the soil, the seedling needles also move in an inclined manner. In the process of pulling the seedling needles out of the soil, if the contact angle with the ground film is not properly controlled, the ground film at the edge of the seedling needles will be pulled upward, causing the round holes to tear and expand into cracks, thereby destroying the integrity of the ground film; at the same time, in the process of inclined pulling out, the soil's covering force on the seedling roots will be weakened due to the deviation of the pulling out angle. If the seedling needles are pulled out too quickly, the inserted seedlings will easily be pulled out, resulting in "floating seedlings" or seedlings falling over, and manual seedling replacement is required.

DETAILED DESCRIPTION

[0020] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0021] Example 1

[0022] The present embodiment discloses an integrated rice planting and film covering and transplanting device. Considering that in the normal use of the existing rice planting and film covering and transplanting device, the seedling needles are usually inserted into the soil in an inclined manner and pulled out upward in an inclined manner. During the pulling out process, the inclined seedling needles will come into contact with the ground film, pulling the ground film upward and destroying the integrity of the ground film. In addition, during the pulling out process, the covering force of the soil on the roots of the seedlings will be weakened due to the deviation of the pulling out angle, causing the seedling needles to easily pull out the inserted seedlings, resulting in "floating seedlings" or seedlings falling. In contrast, the present embodiment solves this problem by the following means: An integrated device for film covering and transplanting rice for rice planting, such as Figures 1-6 As shown, it includes a connecting frame 1, a covering module is provided on the connecting frame 1, a seedling storage mechanism 2 is installed on the connecting frame 1, several connecting blocks 3 are provided on one side of the connecting frame 1, a power piece is provided on the connecting block 3, a symmetrically distributed transmission module 4 is provided on the connecting block 3, and the transmission module 4 is provided with two connecting plates 5, the connecting plate 5 is fixedly connected to the mounting shell 6, and the mounting shell 6 is slidably connected with a connecting shell 7, a first spring 71 is fixed between the connecting shell 7 and the mounting shell 6, the connecting shell 7 is fixedly connected to the fixed shell 8, the fixed shell 8 passes through the mounting shell 6 and is slidably connected thereto, the fixed shell 8 is fixedly connected to a seedling remover 9 for taking the seedlings, the fixed shell 8 is slidably connected to a seedling pusher 10, and the seedling pusher 10 passes through the connecting shell 7 and is slidably connected thereto, the seedling pusher 10 is fitted with the seedling remover 9 on the same fixed shell 8, and a transmission assembly is provided on the mounting shell 6, and the transmission assembly is used to change the position of the seedling pusher 10.

[0023] In the above scheme, the left side of the connecting frame 1 is connected to the existing traction device, and the covering module on the connecting frame 1 is an existing device, and the seedling storage mechanism 2 is located on the upper side of the right part of the connecting frame 1 for placing rice seedlings; the specific number of connecting blocks 3 is selected by the staff, and three are used as an example in the figure and the text, and the power parts and transmission modules 4 on the connecting block 3 are both existing devices, wherein the transmission module 4 can be selected as a gear box or other device, and the power parts on the connecting block 3 drive the corresponding two connecting plates 5 to rotate synchronously through the transmission module 4; under normal conditions, the first spring 71 is in a compressed state; the seedling remover 9 is an existing device for taking seedlings and transplanting them into the soil; the seedling pusher 10 is used to push the seedlings on the corresponding seedling remover 9 into the soil. Under normal conditions, the lower side of the seedling pusher 10 is flush with the lower side of the corresponding seedling remover 9, and the seedling pusher 10 blocks the lower port of the seedling removal area on the corresponding seedling remover 9.

[0024] Further, such as Figure 4-Figure 6As shown, the transmission assembly includes a drive shaft 11, which is arranged on the transmission module 4, and the transmission module 4 transmits the power of the power piece to the drive shaft 11. The drive shaft 11 passes through the mounting shell 6 and is rotatably connected thereto. The drive shaft 11 is fixedly connected to a first gear 12, and the first gear 12 is located in the mounting shell 6. The connecting shell 7 is rotatably connected to a connecting shaft 14, and the connecting shaft 14 is fixedly connected to a second gear 13. The first gear 12 is used to transmit power to the second gear 13. The second gear 13 is located outside the connecting shell 7, and the connecting shaft 14 is fixedly connected to a missing gear 15. The missing gear 15 is located in the connecting shell 7. The seedling pusher 10 is provided with a tooth portion that meshes with the corresponding missing gear 15. A push plate 26 is fixed to the seedling pusher 10, and a second spring 16 is fixed between the push plate 26 and the connecting shell 7. A limiting assembly is provided on the connecting shell 7, and the limiting assembly is used to maintain the relative position of the connecting shell 7 and the corresponding mounting shell 6.

[0025] In the above scheme, the power member on the connecting block 3 drives the corresponding driving shaft 11 to rotate through the corresponding transmission module 4, so that the driving shaft 11 and the corresponding connecting plate 5 rotate relative to each other; the line connecting the center point of the first gear 12 and the center point of the corresponding second gear 13 is parallel to the central axis of the connecting shell 7, so that when the connecting shell 7 moves relative to the adjacent mounting shell 6, the second gear 13 can move synchronously with the connecting shell 7 and thus separate from the corresponding first gear 12; the missing gear 15 drives the seedling pusher 10 to move through the teeth thereon during the rotation process, and compresses the corresponding second spring 16 in the process.

[0026] Further, such as Figure 5 and Figure 6 As shown, the seedling extractor 9 is provided with a seedling extracting area, and the length of the teeth portion on the seedling pusher 10 is greater than the length of the seedling extracting area on the seedling extractor 9.

[0027] In the above solution, the seedling picking area of ​​the seedling picking device 9 is provided with symmetrically distributed inclined surfaces, and the distance between the two inclined surfaces gradually decreases from bottom to top.

[0028] Further, such as Figure 4-Figure 7 As shown, the limit assembly includes symmetrically distributed first limit pins 17, and the symmetrically distributed first limit pins 17 are all slidably connected to the connecting shell 7. Symmetrically distributed limit grooves are provided on the mounting shell 6. The first limit pins 17 slide in the corresponding limit grooves on the corresponding mounting shells 6. Symmetrically distributed fixing blocks 18 are fixed in the connecting shell 7. A third spring 19 is fixed between the fixing blocks 18 and the corresponding first limit pins 17. The first limit pin 17 consists of a cylindrical portion and a hemispherical portion. The depth of the limit groove on the mounting shell 6 is greater than the radius of the hemispherical portion of the first limit pin 17.

[0029] In the above scheme, under normal conditions, the first limit pin 17 is located in the corresponding limit groove on the corresponding mounting shell 6; the third spring 19 is always in a compressed and force-storing state, used to maintain the relative position of the first limit pin 17; the depth of the limit groove on the mounting shell 6 is limited to ensure that the first limit pin 17 can connect and fix the corresponding mounting shell 6 and the corresponding connecting shell 7 under normal conditions.

[0030] Further, such as Figure 2 As shown, an arc-shaped plate 191 is fixed to the connecting block 3 , and the arc-shaped plate 191 is used to squeeze the connecting shell 7 on the same connecting block 3 .

[0031] Further, such as Figure 6 As shown, the mounting shell 6 is provided with symmetrically distributed inclined surfaces, and the inclined surfaces on the mounting shell 6 are used to guide the corresponding first limit pins 17. When the mounting shell 6 is in a vertical state, the length of the projection of the inclined surfaces on the mounting shell 6 on the horizontal plane is greater than the length of the projection of the upper limit groove on the mounting shell 6 on the horizontal plane.

[0032] In the above solution, the shape of the inclined surface on the mounting shell 6 is limited, so that when the connecting shell 7 and the corresponding mounting shell 6 move relative to each other, the first limiting pin 17 can be squeezed and moved by the corresponding inclined surface on the corresponding mounting shell 6.

[0033] Further, such as Figure 6-Figure 8 As shown, the limiting assembly also includes a moving frame 20, which is slidingly connected to the corresponding connecting shell 7 in a limiting manner. The moving frame 20 is fixed with a symmetrically distributed fixed plate 21, and the opposite sides of the symmetrically distributed fixed plates 21 are rotatably connected with a first moving plate 22. A first torsion spring 23 is fixed between the first moving plate 22 and the adjacent fixed plate 21. The opposite sides of the symmetrically distributed first moving plates 22 are rotationally connected with a second moving plate 24, and a second torsion spring 241 is fixed between the second moving plate 24 and the corresponding first moving plate 22. A connecting rope 25 is fixed between the fixed plate 21 and the corresponding first limiting pin 17. The connecting rope 25 passes through the corresponding fixed block 18, and the second moving plate 24 is located on the moving path of the push plate 26.

[0034] In the above solution, the movable frame 20 can only slide up and down in the connecting shell 7 .

[0035] Further, such as Figure 7 As shown, the elastic coefficient of the first torsion spring 23 is greater than the elastic coefficient of the third spring 19 , the elastic coefficient of the second torsion spring 241 is less than the elastic coefficient of the third spring 19 , and the elastic coefficient of the second spring 16 is greater than the elastic coefficient of the first torsion spring 23 .

[0036] In the above scheme, the push plate 26 can contact the corresponding two second movable plates 24 during the movement and squeeze the two second movable plates 24, while ensuring that the push plate 26 can drive the corresponding first limit pin 17 to move horizontally by squeezing the corresponding second movable plates 24 during the downward movement; ensuring that the seedling pusher 10 can drive the movable frame 20 to move downward in the process of driving the push plate 26 to move downward.

[0037] The specific workflow of the above solution is as follows: When it is necessary to use this device to plant rice, the staff first connects the connecting frame 1 to the traction device. After the connection is completed, a certain amount of rice seedlings are placed on the seedling storage mechanism 2, and then the traction device is started. The traction device drives the connecting frame 1 to move to the left. During the movement, the covering module on the connecting frame 1 covers the ground film on the soil surface.

[0038] As the traction device drives the connecting frame 1 to move to the left, the staff activates the power members on the three connecting blocks 3, and each power member drives the two adjacent transmission modules 4 to rotate. During the rotation process, the transmission module 4 drives the connected connecting plate 5 and the drive shaft 11 to revolve and simultaneously drives the connecting plate 5 and the drive shaft 11 to rotate. The following describes the movement process of the connecting plate 5 on the upper front side as an example: During the rotation process (during the revolution and rotation process), the connecting plate 5 drives the mounting shell 6 to rotate synchronously, and the mounting shell 6 drives all the parts inside it to rotate synchronously. Under the joint action of the transmission module 4 and the connecting plate 5, the angle between the seedling remover 9 and the horizontal plane gradually decreases during the rotation of the transmission module 4. During this process, the connecting shell 7 is always in contact with the lower side of the arc plate 191.

[0039] When the driving shaft 11 rotates, the first gear 12 is engaged with the second gear 13 to rotate, and then the connecting shaft 14 is driven to rotate. The connecting shaft 14 drives the missing gear 15 to rotate. The missing gear 15 is engaged with the teeth on the seedling pusher 10 during the rotation, driving the seedling pusher 10 to move along the fixed shell 8. The seedling pusher 10 drives the push plate 26 to move synchronously. The push plate 26 compresses the second spring 16 during the upward movement to store force. The seedling pusher 10 moves along the seedling remover 9 during the movement, thereby releasing the seedling removal area on the seedling remover 9. When the push plate 26 moves upward to contact the two second movable plates 24, the push plate 26 squeezes the two second movable plates 24 during the continued upward movement, causing the two second movable plates 24 to swing upward around the connection between them and the first movable plate 22 (the two second torsion springs 241 twist and store force). After the push plate 26 moves upward to a position where it loses contact with the two second movable plates 24, the two second movable plates 24 are reset under the action of the corresponding second torsion springs 241.

[0040] When the seedling remover 9 revolves near the seedlings, the angle between the seedling remover 9 and the horizontal plane reaches the minimum value (at this time, the seedling pusher 10 can still move relative to the seedling remover 9), and the seedling remover 9 originally located on the right side rotates to the left side, so that the front transmission module 4 drives the seedling remover 9 to remove the seedlings from the seedling storage mechanism 2 while continuing to rotate. The specific process can refer to the seedling removal process of the existing rice transplanter and will not be described in detail.

[0041] After the lower end of the seedling pusher 10 moves downward to contact the seedlings on the seedling taker 9, the seedling pusher 10 pushes the seedlings in the process of continuing to move downward, thereby pushing the seedlings on the seedling taker 9 into the soil.

[0042] When the push plate 26 moves downward until it contacts the upper sides of the two second movable plates 24, the push plate 26 continues to move downward to squeeze the two second movable plates 24, so that the second movable plate 24 drives the adjacent first movable plate 22 to move downward, and the first movable plate 22 drives the adjacent fixed plate 21 to move downward synchronously (the two fixed plates 21 jointly drive the movable frame 20 to move downward), and the fixed plate 21 pulls the adjacent connecting rope 25 during the downward movement, so that the connecting rope 25 drives the adjacent first limit pin 17 to move (the first limit pin 17 squeezes the adjacent third spring 19 during the movement to accumulate force), and the two first limit pins 17 approach each other. During this process, the first limit pin 17 gradually separates from the adjacent limit groove on the mounting shell 6.

[0043] When the two third springs 19 are compressed to the limit state, the moving frame 20 moves downward to the lowest point, the distance between the two first limit pins 17 is the smallest, and the first limit pin 17 loses contact with the mounting shell 6. At this time, the seedling pusher 10 continues to move downward, and the missing gear 15 is still not engaged with the teeth on the seedling pusher 10. Then the first spring 71 drives the connecting shell 7 to move upward synchronously, and the connecting shell 7 drives all parts on it to move upward synchronously relative to the mounting shell 6, so that the first gear 12 is separated from the second gear 13 (the missing gear 15 no longer rotates at this time), and the seedling remover 9 is pulled upward from the soil, thereby reducing the degree of tearing of the mulch film, alleviating the disturbance to the seedlings, and improving the uprightness and uniformity of transplanting. At the same time, the seedling remover 9 is scraped and cleaned by the mounting shell 6, and the soil or other impurities remaining on the seedling remover 9 are cleaned, thereby ensuring that the seedling remover 9 can smoothly carry out the subsequent seedling removal process, reducing the probability of seedling removal failure due to impurities remaining on the seedling remover 9.

[0044] During the reverse movement, the two first limit pins 17 drive the moving frame 20 to move upward relative to the connecting shell 7 through the two connecting ropes 25 until the seedling pusher 10 continues to move downward to the limit position under the action of the second spring 16, and the lower side of the seedling pusher 10 is lower than the lower side of the seedling remover 9.

[0045] During the movement of the seedling pusher 10 and the removal of the seedling remover 9 from the soil, the transmission module 4 continues to drive the connecting plate 5 located on the left side to continue rotating under the action of the power parts, until the connecting plate 5 located on the left side rotates to the right side, and the transmission module 4 drives the connecting plate 5 to move upward, thereby driving the mounting shell 6 and the parts used thereon to move upward synchronously.

[0046] After the connecting shell 7 moves upward to contact the arc plate 191, the arc plate 191 limits the connecting shell 7. At this time, the mounting shell 6 continues to move upward, so that the connecting shell 7 is squeezed by the arc plate 191 and resets downward relative to the mounting shell 6. In the process of resetting, the two inclined surfaces on the mounting shell 6 respectively squeeze the corresponding first limit pins 17, so that the two first limit pins 17 are close to each other, thereby compressing the two third springs 19 to store force. When the two third springs 19 are compressed to the limit state, the hemispheres of the two first limit pins 17 are in contact with the inner wall of the mounting shell 6. At this time, the connecting shell 7 can still move downward relative to the mounting shell 6. Move, compress the first spring 71 and accumulate force. When the two first limit pins 17 move downward to be aligned with the corresponding limit grooves on the mounting shell 6, the first limit pin 17 is reset under the action of the third spring 19, so that the first limit pin 17 is reinserted into the corresponding limit groove on the mounting shell 6, and the mounting shell 6 and the connecting shell 7 are fixed, that is, the connecting shell 7 is reset to a normal state relative to the mounting shell 6 (in this process, the first gear 12 and the second gear 13 are re-engaged, and the drive shaft 11 continues to transmit the second gear 13 to rotate through the first gear 12) for subsequent use, and repeat the above steps to continue planting the remaining rice seedlings.

[0047] After the staff uses the device to plant rice in a designated area (the area is selected by the staff), the device is removed from the rice field and is cleaned and maintained for subsequent use.

[0048] Example 2

[0049] On the basis of Example 1, an integrated film covering and transplanting device for rice planting was further optimized.

[0050] like Figure 4 、 Figure 5 、 Figure 9 and Figure 10 As shown, it also includes several auxiliary components, which are used to straighten the seedlings. The auxiliary components are arranged between the corresponding mounting shell 6 and the corresponding seedling remover 9. The auxiliary components include a symmetrically distributed movable shell 27. The symmetrically distributed movable shells 27 are all slidably connected to the seedling remover 9. The symmetrically distributed movable shells 27 are all slidably connected to the corresponding mounting shell 6. The movable shell 27 is hinged with a swing plate 28. A third torsion spring 29 is fixed between the movable shell 27 and the corresponding swing plate 28. The mounting shell 6 is slidably connected with a symmetrically distributed second limit pin 30. A fourth spring 31 is fixed between the second limit pin 30 and the mounting shell 6. A positioning groove is provided on the movable shell 27. The second limit pin 30 slides in the positioning groove on the corresponding movable shell 27. The second limit pin 30 consists of a hemispherical portion and a cylindrical portion. The depth of the positioning groove on the movable shell 27 is less than the diameter of the hemispherical portion of the second limit pin 30. The elastic coefficient of the fourth spring 31 is less than the elastic coefficient of the first spring 71.

[0051] In the above scheme, the swing plate 28 is located on the lower side of the adjacent movable shell 27; when the swing plate 28 is in contact with the corresponding seedling remover 9, the third torsion spring 29 is in a force storage state; the two second limit pins 30 are symmetrically distributed front and back, and are used to limit the corresponding movable shell 27.

[0052] Furthermore, Figure 9 As shown, the maximum distance between the swing plate 28 and the corresponding mounting shell 6 is smaller than the maximum distance between the seedling extractor 9 and the corresponding mounting shell 6.

[0053] In the above solution, the position of the swing plate 28 is limited so that the swing plate 28 supports the portion above the root of the seedling.

[0054] The specific working process of the above solution is as follows (this embodiment is described by taking the movement process of the front lower connecting shell 7 as an example): In the process of the connecting shell 7 driving the seedling extractor 9 to move upward relative to the mounting shell 6, the seedling extractor 9 moves upward relative to the two movable shells 27. When the seedling extractor 9 moves upward to a position where it loses contact with the two swing plates 28, the two swing plates 28 swing under the action of the adjacent third torsion springs 29, respectively, so that the distance between the lower sides of the two swing plates 28 is reduced. When the two swing plates 28 swing to the time when the inner lower end edges thereof are flush with the lower end of the seedling extracting area of ​​the seedling extractor 9 (that is, the predetermined support distance between the two swing plates 28 is reached), the two swing plates 28 stop moving. The two swing plates 28 support the stems of the seedlings in the process of the seedling extractor 9 moving upward, thereby extending the support time of the seedlings, ensuring that the seedlings are in a vertical state, and ensuring that the roots of the seedlings can be firmly buried in the mud.

[0055] When the seedling remover 9 moves upward to the limit position relative to the movable shell 27, the seedling remover 9 drives the two movable shells 27 to move upward synchronously in the process of continuing to move upward. The movable shell 27 squeezes the adjacent second limit pins 30 during the movement, so that the two second limit pins 30 are squeezed and move away from each other. At the same time, the second limit pin 30 squeezes the adjacent fourth spring 31 during the movement, so that the fourth spring 31 is compressed and accumulates force. Until the connecting shell 7 moves upward to the limit position relative to the mounting shell 6, the two movable shells 27 stop moving synchronously.

[0056] When the two movable shells 27 move downwards, the second limiting pin 30 will re-enter the positioning groove of the adjacent movable shell 27 under the action of the adjacent fourth spring 31, and limit the movable shell 27 so that the movable shell 27 no longer moves downwards (at the same time, the movable shell 27 moves downwards to the limit position), and then the seedling remover 9 moves downwards relative to the movable shell 27 and squeezes the two swinging plates 28, causing the two swinging plates 28 to swing, and in the process of swinging, the two third torsion springs 29 are twisted and stored force for subsequent use, and the above steps are repeated to continue planting the remaining rice seedlings.

[0057] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
