Description

Technical Field

[0001] The present invention relates to the technical field of rice transplanters, and more particularly, to a rice transplanter capable of adjusting the transplanting depth and its usage method. Background Art

[0002] In agricultural production, rice transplanters, as important agricultural machinery, have greatly improved the efficiency of rice planting. However, there are still some deficiencies in the actual application of existing rice transplanters, especially the problems in transplanting depth adjustment are particularly prominent.

[0003] Traditional rice transplanters usually adopt a fixed transplanting depth setting and cannot flexibly adjust the transplanting depth according to different soil conditions, seedling varieties or agronomic requirements. This limitation may lead to the following problems: First, in the case of transplanting at a fixed depth, if the insertion is too shallow, the seedlings will float on the water surface and cannot take root firmly, affecting growth. If the insertion is too deep, the seedlings will be difficult to grow normally and may even die. Second, for different varieties of seedlings, different soil types and climatic conditions, etc., the suitable transplanting depth will also vary. Although some existing rice transplanters have a certain depth adjustment function, the adjustment is inaccurate and manual adjustment is required after stopping the machine, which is not only time-consuming and laborious, but also reduces the operation efficiency.

[0004] Furthermore, when existing rice transplanters face complex fields (such as uneven fields), it is difficult to automatically adapt to terrain changes and maintain the transplanting depth, and the adaptability is weak. This will result in uneven transplanting depth in the same field, thus affecting the overall yield and quality of rice. Summary of the Invention

[0011] Further, the lower support adjustment frame includes two hydraulic cylinders installed side by side and spaced apart on the main body of the transplanter. The output ends of the two hydraulic cylinders are hinged to the bottom surface of the peripheral shell. Two vertical ear plates are installed on the main body of the transplanter and away from the two hydraulic cylinders. A shaft member is installed between the two vertical ear plates, and several support plate members are installed at equal intervals at one end on the shaft member and connected to the bottom surface of the peripheral shell at the other end.

[0012] Further, the attitude adjustment mechanism further includes a support table installed on the main body of the transplanter, and an electronic level installed on the support table;

[0016] The first hollow long box is communicated with an outlet of the electronically controlled three-way valve through a connecting pipe.

[0017] Further, the protecting and inserting mechanism further includes a second hollow long box installed on the back surface of the central panel, and several horn-shaped nozzles are connected to the second hollow long box at equal intervals from below;

[0018] The second hollow long box is connected to another outlet of the electric control three-way valve through a connecting pipe;

[0019] A plurality of the horn-shaped nozzles are located above a plurality of the finger-shaped leather sleeves;

[0020] A plurality of the horn-shaped nozzles and a plurality of the finger-shaped leather sleeves respectively correspond to a plurality of the transplanting claws of the transplanting mechanism.

[0024] Guard frames are arranged on the peripheries of the two seat frames, and the two electric winches are respectively located within the two guard frames.

[0025] According to the second aspect of the present invention, a method for using a transplanter capable of adjusting the transplanting depth is provided:

[0026] S1: Before starting transplanting, according to the actual transplanting depth, selectively drive two first electric push rods or two hydraulic cylinders to drag the main board body up and down along the outer shell, so as to raise or lower the seedling tray and the transplanting mechanism as a whole, or jack up or lower the main board body in a circumferential direction, so that the positions of the seedling tray and the transplanting mechanism change in an arc as a whole. After adjusting the heights of the seedling tray and the transplanting mechanism, drive the seedling tray and the transplanting mechanism to travel and automatically transplant seedlings through the main body of the transplanter;

[0027] S2: After the level of the field changes, the tilting degree of the main body of the transplanter and the level degree of the electronic level change accordingly. At this time, the electronic level cooperates with the controller to correspondingly control the start of two first electric push rods or two hydraulic cylinders to adjust the heights of the seedling tray and the transplanting mechanism to different degrees, so as to obtain a new transplanting depth;

[0028] S3: When using a deeper transplanting depth, start the high-pressure air pump to generate high-pressure air flow, and all the air flow is conveyed into the first hollow long box through the electric control three-way valve, so that a plurality of finger-shaped leather sleeves gradually start to inflate and expand. At the same time, drive two second electric push rods to insert a plurality of finger-shaped leather sleeves into the soil. As the plurality of finger-shaped leather sleeves expand, holes are opened at the positions to be transplanted, and the main body of the transplanter and the transplanting mechanism immediately follow and insert the seedlings into the holes;

[0029] S4: When the water level in the field is relatively high, keep the high-pressure air pump running and send all the air flow into the second hollow long box through the electronically controlled three-way valve. Then, strong air flow is ejected from several horn-shaped nozzles, blowing the water surface near the position where rice seedlings are to be transplanted into a concave shape. Subsequently, the main body of the rice transplanter and the rice transplanting mechanism follow closely to insert the rice seedlings into the field.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The rice transplanter capable of adjusting the transplanting depth can automatically raise or lower the height of the rice transplanting mechanism while transplanting through the attitude adjustment mechanism, thereby reducing or increasing the distance between the rice transplanting mechanism and the field, and then changing the final transplanting depth. This ensures that different transplanting depths can be obtained without manual adjustment after stopping the machine, effectively improving the operation efficiency. At the same time, the attitude adjustment mechanism can adjust the height of the rice transplanting mechanism in two ways, with relatively small and large amplitudes, greatly improving the adjustment fineness and thus the planting quality.

[0032] 2. Under the action of the attitude adjustment mechanism, the rice transplanter capable of adjusting the transplanting depth can sense the flatness of the field in real time and make corresponding controls, thereby ensuring that the transplanting depth can be adaptively adjusted according to the changes in the terrain, and ensuring that rice can be transplanted at a uniform depth even if there are height differences in the field.

[0033] 3. The rice transplanter capable of adjusting the transplanting depth can create a depression on the mud or water surface through the seedling protection mechanism, thereby reducing the relative horizontal height of the transplanting position when the transplanting depth is relatively deep, effectively reducing the thickness of the soil layer and water layer that the rice seedlings need to pass through, and providing a strong guarantee for the smooth planting of the rice seedlings.

[0034] 4. The rice transplanter capable of adjusting the transplanting depth can meet different transplanting depths and diverse planting requirements, and at the same time has good environmental adaptability, which well guarantees the transplanting efficiency and the overall transplanting quality.

[0050] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0051] As Figures 1 - 12As shown in the figure, a transplanter capable of adjusting the transplanting depth is characterized by comprising a transplanter main body 1, a seedling tray 2 and a transplanting mechanism 3. The seedling tray 2 is connected to the transplanting mechanism 3. An attitude adjusting mechanism 4 is installed on the transplanter main body 1, and the transplanting mechanism 3 is connected to the attitude adjusting mechanism 4. A protecting and inserting mechanism 5 is arranged on the transplanter main body 1 and the transplanting mechanism 3, wherein:

[0052] Driving the attitude adjusting mechanism 4 can enable the transplanting mechanism 3 and the seedling tray 2 to move within a spatial range, so as to integrally change the attitudes of the transplanting mechanism 3 and the seedling tray 2;

[0053] The protecting and inserting mechanism 5 is suitable for reducing the relative horizontal height of the transplanting point for the seedlings to penetrate deeply. The transplanter capable of adjusting the transplanting depth can automatically raise or lower the height of the transplanting mechanism 3 while transplanting through the attitude adjusting mechanism 4, thereby reducing or increasing the distance between the transplanting mechanism 3 and the field, and then changing the final transplanting depth, ensuring that different transplanting depths can be obtained without manual adjustment after stopping, effectively improving the operation efficiency. At the same time, the attitude adjusting mechanism 4 can relatively slightly and greatly adjust the height of the transplanting mechanism 3 in two ways, greatly improving the adjustment fineness, thereby improving the planting quality. Under the action of the attitude adjusting mechanism 4, the transplanter capable of adjusting the transplanting depth can sense the flatness of the field in real time and make corresponding controls, so as to ensure that the transplanting depth can be adaptively adjusted along with the change of the terrain, ensuring that the transplanting can be completed at a uniform depth even if there is a height difference in the field. Through the protecting and inserting mechanism 5, a depression can be created on the soil or water surface, so as to reduce the relative horizontal height of the transplanting position when the transplanting depth is deeper, effectively reducing the thickness of the soil layer and water layer that the seedlings need to pass through, providing a strong guarantee for the smooth planting of the seedlings. The transplanter capable of adjusting the transplanting depth can meet different transplanting depths, meet diversified planting requirements, and at the same time has good environmental adaptability, well ensuring the transplanting efficiency and the overall transplanting quality.

[0054] Optionally, the attitude adjusting mechanism 4 includes a lower support adjusting frame 41 installed on the transplanter main body 1, a peripheral shell 42 installed on the lower support adjusting frame 41. The two ends of the peripheral shell 42 are in a groove shape, and two groups of several rotating columns 43 are respectively arranged in the grooves at the two ends of the peripheral shell 42. A main board body 44 is placed on the peripheral shell 42, and both sides of the main board body 44 are respectively abutted against the two groups of several rotating columns 43. Two mounting panels 45 are respectively connected to the top surfaces at the two ends of the peripheral shell 42. Two first electric push rods 46 are respectively arranged on the two mounting panels 45, and a multi-point uniform transmission member 47 is connected to the output ends of the two first electric push rods 46, and the multi-point uniform transmission member 47 is connected to the top of the main board body 44;

[0055] The lower end of the main board body 44 is connected to the transplanting mechanism 3. After driving the two first electric push rods 46, the driving force can be transmitted to the main board body 44 through the multi-point uniform transmission part 47, and then the main board body 44 can be pushed up or pulled down along the outer shell 42, so as to synchronously raise or lower the height of the transplanting mechanism 3, thereby changing the distance between the transplanting mechanism 3 and the field. The transplanting path of the transplanting mechanism 3 remains unchanged, and then the seedlings can be inserted deeper or shallower into the field to obtain different transplanting depths, ensuring to meet different transplanting requirements. And by controlling the two first electric push rods 46, the transplanting depth can be adjusted, which can be implemented while transplanting without stopping the machine for manual operation, thus effectively improving the operation efficiency. While the outer shell 42 and the two groups of several rotating columns 43 form a space to limit the main board body 44, the two groups of several rotating columns 43 can rotate along with the up and down movement of the main board body 44, thereby reducing the friction force, so that the two first electric push rods 46 can smoothly push and pull the transplanting mechanism 3, the seedling tray 2 and the seedlings they carry as a whole.

[0056] Optionally, the lower support adjustment frame 41 includes two hydraulic cylinders 411 installed side by side and spaced apart on the transplanting machine main body 1, and the output ends of the two hydraulic cylinders 411 are hinged to the bottom surface of the outer shell 42. Two vertical ear plates 412 are installed on the transplanting machine main body 1 and away from the two hydraulic cylinders 411. A shaft member 413 is installed between the two vertical ear plates 412, and several support plate members 414 are installed at equal intervals at one end on the shaft member 413 and connected to the bottom surface of the outer shell 42 at the other end. Driving the two hydraulic cylinders 411 to generate power can push and pull the outer shell 42 to rotate at a corresponding angle under the action of the shaft member 413, so as to synchronously make the transplanting mechanism 3 perform an arc-shaped movement, and adjust the distance between the transplanting mechanism 3 and the field with a relatively small amplitude, and then cooperate with the relatively large amplitude adjustment brought by the two first electric push rods 46 to effectively improve the fineness of the adjustment of the transplanting depth, improve the planting quality, and ensure the execution effect of the established transplanting depth.

[0057] Optionally, the attitude adjustment mechanism 4 further includes a support table 48 installed on the transplanting machine main body 1, and an electronic level 49 arranged on the support table 48;

[0058] The electronic level 49 is electrically connected to the two first electric push rods 46 and the two hydraulic cylinders 411, and is controlled by a programmable logic controller, i.e., PLC. During rice transplanting, the electronic level 49 constantly monitors the levelness of the rice transplanter main body 1. Once the flatness of the field changes and the value of the electronic level 49 exceeds the established appropriate range and remains for a certain period of time, the programmable logic controller controls the two first electric push rods 46 and the two hydraulic cylinders 411 to drive respectively for an appropriate duration to adjust the height of the rice transplanting mechanism 3, so as to readjust the rice transplanting depth to a state suitable for the current field height, ensure that the rice transplanting depth can be adaptively adjusted with the change of terrain, and ensure that the rice transplanting can be completed at a uniform depth even if there is a height difference in the field, effectively improving the environmental adaptability to ensure the overall rice transplanting quality.

[0059] Optionally, the seedling protecting mechanism 5 includes a high-pressure air pump 51 arranged on the rice transplanter main body 1, an electrically controlled three-way valve 52 installed on the side of the rice transplanting mechanism 3, a central panel 53 connected to the bottom surface of the rice transplanting mechanism 3, a first hollow long box 54 slidably installed on the front side of the central panel 53, two second electric push rods 55 installed on the rice transplanting mechanism 3 in an inverted and spaced manner, and the output ends of the two second electric push rods 55 are both connected to the top of the first hollow long box 54, and a plurality of finger-shaped leather sleeves 56 are connected to the first hollow long box 54 at equal intervals from below;

[0060] The inlet of the electrically controlled three-way valve 52 is connected to the air outlet of the high-pressure air pump 51 through a connecting pipe;

[0061] The first hollow long box 54 is connected to an outlet of the electric control three-way valve 52 through a connecting pipe. When adjusting the transplanting depth and performing deeper transplanting, the high-pressure air pump 51 is started to generate high-pressure air flow. Under the action of the electric control three-way valve 52, the air flow is completely transported into the first hollow long box 54 through the connecting pipe, so that a number of finger-shaped leather sleeves 56 start to inflate and gradually expand. At the same time, two second electric push rods 55 are driven to push the first hollow long box 54 downward, inserting a number of finger-shaped leather sleeves 56 into the soil. As a number of finger-shaped leather sleeves 56 expand, a depression is formed in the soil at the position where the seedlings are to be transplanted. Then, two second electric push rods 55 are immediately driven in the reverse direction to reset a number of finger-shaped leather sleeves 56, leaving a depression, thereby reducing the relative horizontal height of the position where the seedlings are to be transplanted. Subsequently, as the transplanting progresses, the transplanting mechanism 3 immediately inserts the seedlings into the depression area created by a number of finger-shaped leather sleeves 56 to complete the transplanting. In this way, when performing deeper transplanting, it is ensured that the root system of the seedlings is not damaged or bent due to the need for the seedlings to penetrate through thicker soil, which affects the transplanting effect, ensuring the transplanting quality, effectively preventing situations that affect transplanting and the future growth of the seedlings during the transplanting process, and providing a strong guarantee for the smooth planting of the seedlings. At the same time, it is prevented that the transplanting mechanism 3 comes into extensive contact with the soil and is severely clogged by the soil, thereby avoiding affecting normal transplanting.

[0062] Optionally, the seedling protection and insertion mechanism 5 further includes a second hollow long box 57 installed on the back surface of the central panel 53, and a number of horn-shaped nozzles 58 connected to the second hollow long box 57 at equal intervals from below;

[0063] The second hollow long box 57 is connected to the other outlet of the electric control three-way valve 52 through a connecting pipe;

[0064] A number of the horn-shaped nozzles 58 are located above a number of the finger-shaped leather sleeves 56;

[0065] A number of the horn-shaped nozzles 58 and a number of the finger-shaped leather sleeves 56 respectively correspond to a number of transplanting claws of the transplanting mechanism 3. When the water level in the field is relatively high, the high-pressure air pump 51 is started, and the outlet of the electric control three-way valve 52 leading to the first hollow long box 54 is closed, or both outlets of the electric control three-way valve 52 are kept open simultaneously, so that the air flow can be transported into the second hollow long box 57 and diffused and blown out through a number of horn-shaped nozzles 58, using the strong air flow to blow the water surface below, thereby blowing the water surface at the position where the seedlings are to be transplanted and in the vicinity into a concave shape, effectively reducing the relative thickness of the water surface at the position where the seedlings are to be transplanted. In this way, it is effectively prevented that the root system of the seedlings is damaged or bent due to the need for the seedlings to penetrate through a thicker water layer, which affects the transplanting effect, effectively preventing situations that affect transplanting and the future growth of the seedlings during the transplanting process, and providing a strong guarantee for the smooth planting of the seedlings.

[0066] Optionally, the shaft member 413 is a damping rotating shaft. Since the damping rotating shaft has a certain amount of friction itself, a certain amount of force is required to rotate it. Thus, while not preventing the outer shell 42 from rotating, it shares the weight of the transplanting mechanism 3, the seedling tray 2, and the seedlings they carry under normal conditions, making the overall structure more stable and reliable.

[0067] Optionally, two seat frames 6 are provided on the transplanting machine main body 1, and electric winches 7 are respectively provided on the two seat frames 6;

[0068] The ropes on the two electric winches 7 are respectively connected to both ends of the top surface of the main board body 44. When the main board body 44 moves, the two electric winches 7 will unwind or wind up the ropes they have wound, to facilitate the smooth movement of the main board body 44. Under normal conditions, the two electric winches 7 wind up the ropes to a taut state to pull the main board body 44, thereby using the two electric winches 7 to effectively share the weight of the transplanting mechanism 3, the seedling tray 2, and the seedlings they carry, further making the overall structure more stable and reliable, and effectively preventing the shaking of structures such as the main board body 44 from affecting the normal transplanting work;

[0069] A protective frame 8 is provided on the periphery of the two seat frames 6, and the two electric winches 7 are respectively located within the two protective frames 8 to shield and protect the two electric winches 7.

[0070] According to the second aspect of the present invention, a method for using a transplanting machine capable of adjusting the transplanting depth is provided:

[0071] S1: Before starting transplanting, according to the actual transplanting depth, selectively drive the two first electric push rods 46 or the two hydraulic cylinders 411 to drag the main board body 44 up and down along the outer shell 42, so that the seedling tray 2 and the transplanting mechanism 3 are raised or lowered as a whole, or jack up or lower the main board body 44 upward in a circular motion, so that the positions of the seedling tray 2 and the transplanting mechanism 3 change arcuately as a whole. After adjusting the heights of the seedling tray 2 and the transplanting mechanism 3, drive the seedling tray 2 and the transplanting mechanism 3 to move and automatically transplant seedlings through the transplanting machine main body 1;

[0072] S2: After the levelness of the field changes, the tilting degree of the transplanting machine main body 1 and the levelness of the electronic level 49 change accordingly. At this time, the electronic level 49 cooperates with the controller to correspondingly control the two first electric push rods 46 or the two hydraulic cylinders 411 to start, to adjust the heights of the seedling tray 2 and the transplanting mechanism 3 to different degrees, and obtain a new transplanting depth;

[0073] S3: When using a relatively deep rice transplanting depth, start the high-pressure air pump 51 to generate high-pressure air flow, and use the electronically controlled three-way valve 52 to deliver all the air flow into the first hollow long box 54, so that several finger-shaped leather sleeves 56 gradually start to inflate and expand. At the same time, drive the two second electric push rods 55 to insert several finger-shaped leather sleeves 56 into the soil. As several finger-shaped leather sleeves 56 expand, holes are opened at the positions where rice seedlings are to be transplanted, and then the main body 1 of the rice transplanter and the transplanting mechanism 3 follow closely to insert the rice seedlings into the holes.

[0074] S4: When the water level in the field is relatively high, keep the high-pressure air pump 51 running and use the electronically controlled three-way valve 52 to deliver all the air flow into the second hollow long box 57. Then, strong air flow is ejected from several horn-shaped nozzles 58, blowing the water surface near the position where rice seedlings are to be transplanted into a concave shape. Subsequently, the main body 1 of the rice transplanter and the transplanting mechanism 3 follow closely to insert the rice seedlings into the field.

[0075] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

9. The using method of the transplanter capable of adjusting the transplanting depth according to claim 8 is as follows: S1: Before starting transplanting, according to the actual transplanting depth, selectively drive the two first electric push rods (46) or the two hydraulic cylinders (411) to drag the main board body (44) up and down along the outer shell (42), so as to raise or lower the seedling tray (2) and the transplanting mechanism (3) as a whole, or jack up or lower the main board body (44) circumferentially upwards, so that the positions of the seedling tray (2) and the transplanting mechanism (3) change arcwise as a whole. After adjusting the heights of the seedling tray (2) and the transplanting mechanism (3), drive the seedling tray (2) and the transplanting mechanism (3) to move forward and automatically transplant seedlings by the main body (1) of the transplanter; S2: After the level of the field changes, the tilt angle of the main body (1) of the transplanter and the level of the electronic level (49) change accordingly. At this time, the electronic level (49) cooperates with the controller to correspondingly control the start of two first electric push rods (46) or two hydraulic cylinders (411) to adjust the heights of the seedling tray (2) and the transplanting mechanism (3) to different degrees, so as to obtain a new transplanting depth. S3: When using a deeper transplanting depth, start the high-pressure air pump (51) to generate high-pressure air flow, and use the electronically controlled three-way valve (52) to send all the air flow into the first hollow long box (54), so that a number of finger-shaped leather sleeves (56) gradually start to inflate and expand. At the same time, drive two second electric push rods (55) to insert a number of finger-shaped leather sleeves (56) into the soil. As a number of finger-shaped leather sleeves (56) expand, holes are opened at the positions where the seedlings are to be transplanted, and the main body (1) of the transplanter and the transplanting mechanism (3) immediately follow and insert the seedlings into the holes. S4: When the water level in the field is high, keep the high-pressure air pump (51) running and use the electronically controlled three-way valve (52) to send all the air flow into the second hollow long box (57), and then strong air flow is ejected from a number of horn-shaped nozzles (58) to blow out a concave shape on the water surface near the position where the seedlings are to be transplanted. Then, the main body (1) of the transplanter and the transplanting mechanism (3) immediately follow and insert the seedlings into the field.
