Description

Technical Field

[0001] The invention belongs to the technical field of rice transplanters, and in particular relates to a row spacing adjusting device for a rice transplanter. Background Art

[0002] The rice transplanter is a planting machine that plants rice seedlings in paddy fields. It aims to improve the efficiency and quality of transplanting, achieve reasonable density planting, and facilitate the mechanization of subsequent operations.

[0003] In the Chinese patent with publication number CN205946559U, a row spacing adjustment device for a high-speed rice transplanter with adjustable width and narrow rows is mentioned, which relates to agricultural machinery technology, especially the field of transplanter technology. It includes an adjusting screw, a moving block, an adjusting support plate and a fastening bolt. When adjusting the row spacing, loosen the fastening bolt, rotate the adjusting screw through the adjusting handle, so that the moving block moves axially on the adjusting screw, driving the support arm connected to the moving block to move axially to the specified position, and then tighten the fastening bolt to fix the support arm. For each rotation of the adjusting screw, the moving block moves axially by 20mm, and the length of the entire spiral groove ensures that the moving distance of the moving block is between 0 and 150mm, which can achieve a narrow row of 25cm for transplanting rice, and a wide row that is adjustable within the range of 25-40cm. By adjusting to meet the planting density requirements in different regions, wide and narrow row planting can be achieved, and the purpose of ventilation, light transmission, and disease and pest prevention can be achieved, thereby increasing rice yield;

[0004] During use of the row spacing adjustment device of the adjustable wide and narrow row high-speed rice transplanter, when making adjustments, only independent adjustment operations are allowed on the single transplanting mechanisms on both sides. The scope of this adjustment method is relatively limited and may not be able to fully meet the diverse needs in actual operations, making it difficult to achieve accurate configuration of the transplanting mechanisms. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention aims to provide a row spacing adjustment device for a rice transplanter to solve the problem of difficulty in achieving accurate configuration of a rice transplanting mechanism.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The row spacing adjustment device of a rice transplanter comprises:

[0008] Connecting plate;

The supporting block, the arc-shaped limit seat and the mounting rod are each provided with two, and the two supporting blocks are respectively mounted at the two ends of the supporting structure, the two arc-shaped limit seats are respectively mounted at one end of the two supporting blocks, and the two mounting rods are both mounted at the other end of the supporting structure, and the supporting structure is threadedly connected to the outer surface of the screw rod.

[0011] Preferably, the output end of the motor passes through one end of the mounting frame and is fixedly connected to one end of the screw rod, a stabilizing rod is fixedly connected between the two connecting blocks, and one side of the mounting structure is movably connected to the outer surface of the stabilizing rod.

[0013] Preferably, the connecting frame includes a screw rod, a support seat, a frame body, a limit block and a rotating block, the support seat bearing is connected to the middle outer surface of the screw rod, the frame body is fixedly connected to one end of the support seat, one end of the frame body is provided with four through holes at equal distances, the limit block is fixedly connected to one end of the screw rod, the rotating block is fixedly connected to the other end of the screw rod, and the frame body is fixedly connected to one end of the displacement plate.

[0014] Preferably, the adjustment structure includes a first movable frame and a second movable frame, the top and bottom ends of the first movable frame are fixedly connected to fixed blocks, and a first insertion rod is provided in the middle of one end of the two fixed blocks, two insertion holes are provided at one end of the first movable frame, the top and bottom ends of the second movable frame are fixedly connected to a limiting plate, one end of the second movable frame is fixedly connected to two second insertion rods, and the first movable frame and the second movable frame are both threadedly connected to the outer surface of the screw rod.

[0015] Preferably, the first movable frame and the second movable frame are both movably connected to the outer surface of the stabilizing rod, the two second insertion rods are respectively movably connected to the two insertion holes, and the limiting plates are respectively movably connected to the outer surfaces of the two first insertion rods.

[0016] Preferably, opposite thread grooves are respectively provided on the outer surfaces of both sides of the screw rod.

[0017] Preferably, two opposite thread grooves are arranged on both sides of the outer surface of the screw.

[0018] Preferably, the two first penetration rods and the two second penetration rods are movably connected to the four perforations respectively.

[0019] Preferably, the second movable frames are configured as L-shaped structures.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) By setting a motor, a screw, a support structure, a support block, an arc-shaped limit seat and a mounting rod, after starting the motor, the output end of the motor immediately starts to drive the screw to rotate, so that the support structure is smoothly displaced. This displacement not only causes the support block to move accordingly, but also causes the arc-shaped limit seat to be displaced accordingly. The support structure can effectively pull the rice transplanting mechanism to move through the mounting rod, thereby realizing the precise adjustment of the row spacing between the mounting structures. According to the actual row spacing adjustment needs, multiple mounting structures can be quickly and flexibly driven to make coordinated adjustments, greatly expanding the adjustment range of the row spacing. Through this wide and narrow row spacing adjustment function, the row spacing can be scientifically adjusted according to the growth characteristics and environmental conditions of the crops, which not only helps to improve the ventilation conditions and light distribution of the rice field, but also effectively reduces the occurrence of pests and diseases, provides a more superior environment for the growth of rice, helps to increase the rice yield, and brings more significant economic benefits to agricultural production.

[0022] (2) By setting a screw rod, a support seat, a frame body, a limit block and a rotating block, the rotation of the rotating block drives the screw rod to rotate smoothly inside the support seat. This rotation action prompts the first movable frame and the second movable frame to move in opposite directions respectively. With the displacement of the first movable frame and the second movable frame, the mounting rods driven by them respectively move again. This movement not only involves the mounting rod itself, but also drives the fine displacement of the support block and the arc-shaped limit seat, so that the distance between the rice transplanting mechanisms can be adjusted more accurately, thereby ensuring the efficiency and accuracy of the rice transplanting operation.

[0023] (3) During the movement of the first movable frame and the second movable frame, the displacement of the first movable frame drives the fixed block to move synchronously, and the movement of the second movable frame drives the corresponding displacement of the limit plate and the second insertion rod. This design ensures that the second insertion rod can slide smoothly in the insertion hole. At the same time, the first insertion rod also slides stably under the guidance of the limit plate, which greatly improves the stability and accuracy of the displacement of the first movable frame and the second movable frame.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0032] Embodiment 1:

[0033] See also Figure 1 - Figure 6 As shown, the row spacing adjustment device of the rice transplanter comprises:

[0034] Connecting plate 1;

[0035] Both ends of the connecting plate 1 are provided with connecting blocks 3, and a mounting frame 2 is installed on one side of the top of the two connecting blocks 3, and a screw rod 4 is movably connected between the two mounting frames 2, and a plurality of mounting structures 6 are equidistantly threadedly connected on the outer surface of the screw rod 4, and a motor 5 is installed at one end of one of the mounting frames 2;

[0036] The mounting structure 6 includes a supporting structure 61, a supporting block 62, an arc-shaped limit seat 63 and a mounting rod 64. There are two supporting blocks 62, two arc-shaped limit seats 63 and two mounting rods 64, and the two supporting blocks 62 are respectively mounted at both ends of the supporting structure 61, the two arc-shaped limit seats 63 are respectively mounted at one end of the two supporting blocks 62, and the two mounting rods 64 are both mounted at the other end of the supporting structure 61. The supporting structure 61 is threadedly connected to the outer surface of the screw rod 4.

[0037] As can be seen from the above, the device is installed on the rice transplanter through two mounting frames 2, and the sub-transplanting mechanism is installed on the end of the mounting rod 64 away from the support structure 61. The motor 5 is started, and its output end immediately starts to drive the screw 4 closely connected to it to rotate. As the screw 4 rotates, the support structure 61 that is closely matched with it through the thread also moves accordingly. This movement not only drives the support block 62 fixedly connected to the support structure 61 to move, but also causes the arc-shaped limit seat 63 that is also fixedly connected to the support structure 61 to move. The support structure 61 also effectively pulls the sub-transplanting mechanism to make corresponding position adjustments through the mounting rod 64 installed thereon, so that the row spacing between the mounting structures 6 can be flexibly adjusted, thereby meeting different operation requirements.

[0038] For details about the above, refer to Figure 2 and Figure 4 As shown, the output end of the motor 5 passes through one end of the mounting frame 2 and is fixedly connected to one end of the screw rod 4, a stabilizing rod 7 is fixedly connected between the two connecting blocks 3, and one side of the mounting structure 6 is movably inserted and connected to the outer surface of the stabilizing rod 7;

[0039] The supporting structure 61 includes a displacement plate 611, a connecting frame 612, a reinforcing plate 613 and an adjusting structure 614. The connecting frame 612 is fixedly connected to one end of the displacement plate 611, the reinforcing plate 613 is fixedly connected between the connecting frame 612 and the displacement plate 611, the adjusting structure 614 is installed on the outer surfaces of both sides of the connecting frame 612, and the displacement plate 611 is threadedly connected to the outer surface of the screw rod 4.

[0040] As can be seen from the above, in order to ensure the stability of the mounting structure 6, a stabilizing rod 7 is designed, and it is movably connected with the mounting structure 6. This connection method not only provides an effective limiting effect for the mounting structure 6, but also greatly enhances its overall stability. In addition, in order to further improve the firmness of the connecting frame 612, a reinforcing plate 613 is provided, which not only significantly improves the structural strength of the connecting frame 612, but also provides it with additional support, making the entire mounting structure 6 more stable and reliable.

[0041] Embodiment 2:

[0042] refer to Figure 5 and Figure 6 As shown, the connecting frame 612 includes a screw rod 21, a support seat 22, a frame body 23, a limit block 25 and a rotating block 26. The support seat 22 is connected to the middle outer surface of the screw rod 21 with a bearing, the frame body 23 is fixedly connected to one end of the support seat 22, and one end of the frame body 23 is provided with four through holes 24 at equal distances. The limit block 25 is fixedly connected to one end of the screw rod 21, the rotating block 26 is fixedly connected to the other end of the screw rod 21, and the frame body 23 is fixedly connected to one end of the displacement plate 611;

[0043] The adjustment structure 614 includes a first movable frame 41 and a second movable frame 42. The top and bottom ends of the first movable frame 41 are fixedly connected with fixed blocks 43, and the middle part of one end of the two fixed blocks 43 is provided with a first insertion rod 44. One end of the first movable frame 41 is provided with two insertion holes 45, the top and bottom ends of the second movable frame 42 are fixedly connected with a limiting plate 47, one end of the second movable frame 42 is fixedly connected with two second insertion rods 46, and the first movable frame 41 and the second movable frame 42 are both threadedly connected to the outer surface of the screw rod 21.

[0044] As can be seen from the above, when the screw rod 4 starts to rotate, it uses the close fit between its thread and the displacement plate 611 to drive the displacement plate 611 to move smoothly, and this displacement is then transmitted to the frame 23 fixedly connected to the displacement plate 611, so that the frame 23 also moves accordingly, and the movement of the frame 23 further drives the support seat 22 firmly connected thereto to move, and at the same time, this movement also pulls the support block 62, the arc-shaped limit seat 63 and the mounting rod 64 to move together, thereby realizing the preliminary adjustment of the row spacing between the mounting structures 6;

[0045] In order to adjust the line spacing more finely, rotate the rotating block 26. The rotation of the rotating block 26 drives the screw rod 21 fixedly connected thereto to rotate inside the support seat 22. This rotation action causes the first moving frame 41 and the second moving frame 42, which are threadedly connected to the screw rod 21, to move in opposite directions respectively. During the movement, the first moving frame 41 not only drives the fixed block 43 fixedly connected thereto to move synchronously, but also ensures the stability of the entire movement process through its structural connection. At the same time, the movement of the second moving frame 42 drives the corresponding displacement of the limit plate 47 and the second insertion rod 46. During this process, the second insertion rod 46 slides smoothly in the insertion hole 45, and the first insertion rod 44 slides steadily under the guidance of the limit plate 47. These design details jointly improve the accuracy and stability of the displacement of the first moving frame 41 and the second moving frame 42.

[0046] Finally, with the further displacement of the first movable frame 41 and the second movable frame 42, the mounting rod 64 driven by them respectively also moves again. This movement not only involves the mounting rod 64 itself, but also drives the displacement of the support block 62 and the arc-shaped limit seat 63. This series of precise adjustment steps enables us to more accurately adjust the distance between the transplanting mechanisms, thereby meeting the strict requirements for row spacing and plant spacing in rice transplanting operations.

[0047] Preferably, opposite thread grooves are respectively provided on the outer surfaces of both sides of the screw rod 21;

[0048] Two opposite thread grooves are arranged on both sides of the outer surface of the screw 4;

[0049] The two first penetration rods 44 and the two second penetration rods 46 are movably connected to the four through holes 24 respectively;

[0050] The second moving frames 42 are all configured as L-shaped structures.

[0051] As can be seen from the above, opposite thread grooves are respectively provided on the outer surfaces of both sides of the screw rod 21, so that when rotating, the first movable frame 41 and the second movable frame 42 can be driven to move in opposite directions, thereby achieving the purpose of adjusting the line spacing, and the first insertion rod 44 and the second insertion rod 46 are movably connected with the through hole 24, so that the first insertion rod 44 and the second insertion rod 46 can be limited.

[0052] Embodiment three:

[0053] refer to Figure 2 and Figure 6 As shown, the first movable frame 41 and the second movable frame 42 are both movably connected to the outer surface of the stabilizing rod 7, the two second insertion rods 46 are respectively movably connected to the inside of the two insertion holes 45, and the limiting plates 47 are respectively movably connected to the outer surfaces of the two first insertion rods 44.

[0054] As can be seen from the above, the first movable frame 41 and the second movable frame 42 can be movably inserted and connected on the outer surface of the stabilizing rod 7, which not only enables the two to move smoothly under the guidance of the stabilizing rod 7, but also greatly enhances the stability of the first movable frame 41 and the second movable frame 42 during the displacement process through the limiting effect provided by the stabilizing rod 7. The limiting plate 47 is movably inserted into the outer surface of the first insertion rod 44, and the second insertion rod 46 is movably inserted into the insertion hole 45, which further improves the stability of the displacement of the first movable frame 41 and the second movable frame 42.

[0055] Further, the present invention is designed and applied to a rice transplanter. When in use, the device is installed on the rice transplanter through two mounting frames 2, and the transplanting mechanism is arranged at the end of the mounting rod 64, and the end is far away from the support structure 61 to ensure the flexibility of operation. Once the motor 5 is started, its output end immediately drives the screw 4 closely connected thereto to rotate, and this rotation action further causes the displacement plate 611 to produce linear displacement. The movement of the displacement plate 611 drives the frame 23 to move synchronously. The movement of the frame 23 pulls the support seat 22 to move together, which indirectly drives the overall displacement of the support block 62, the arc-shaped limit seat 63 and the mounting rod 64, thereby realizing the preliminary adjustment of the row spacing between the mounting structures 6.

[0056] Next, by rotating the rotating block 26, the rotation of the rotating block 26 drives the screw rod 21 to rotate smoothly inside the support seat 22. This rotation action causes the first mobile frame 41 and the second mobile frame 42 to move in opposite directions respectively. In this process, the displacement of the first mobile frame 41 drives the fixed block 43 to move synchronously, and the movement of the second mobile frame 42 drives the corresponding displacement of the limit plate 47 and the second insertion rod 46. This design ensures that the second insertion rod 46 can slide smoothly in the insertion hole 45, and at the same time, the first insertion rod 44 also slides stably under the guidance of the limit plate 47, which greatly improves the stability and accuracy of the displacement of the first mobile frame 41 and the second mobile frame 42.

[0057] Finally, with the displacement of the first movable frame 41 and the second movable frame 42, the mounting rod 64 driven by them respectively moves again. This movement not only involves the mounting rod 64 itself, but also drives the fine displacement of the support block 62 and the arc-shaped limit seat 63. This series of precise adjustment steps can more accurately adjust the distance between the rice transplanting mechanisms according to actual needs. This precise adjustment capability is crucial to ensuring the efficiency and accuracy of rice transplanting operations. It provides us with a more reliable and efficient operating method, thereby helping agricultural production achieve higher yields and better quality.
