Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and more particularly, to a transplanter with a synchronous fertilization structure and its usage method. Background Art

[0002] With the continuous improvement of the level of agricultural mechanization, transplanters are increasingly widely used in rice planting. In order to avoid the need to arrange manual or mechanical fertilization operations separately after the transplanting operation, transplanters have begun to be commonly equipped with side deep fertilization devices to synchronously complete transplanting and fertilization, greatly reducing the labor intensity and saving labor costs.

[0003] Side deep fertilization refers to a fertilization method in which fertilizers are concentrated and evenly applied to a certain depth of soil while transplanting rice seedlings. Side deep fertilization results in a high fertilizer concentration at the fertilization position, with less microbial uptake, less nitrogen loss, and more fertilizers that can be absorbed and utilized by rice, resulting in a high utilization rate. Compared with conventional broadcasting fertilization, fertilizers are not easily washed away, and the fertilizer utilization rate is greatly improved. Therefore, it is beneficial for rice to absorb fertilizers during the growth period, extend the fertilizer effect, and ensure the nutrient supply during the rice growth period, especially in the later growth stage.

[0004] However, the vast majority of side deep fertilization is pneumatic, that is, fertilizer particles are blown into the soil by air flow. However, when operating in paddy fields, the fertilizer outlet is always wet and adheres to mud, so fertilizers are extremely likely to stick at the fertilizer outlet, causing blockage of the fertilizer outlet or insufficient fertilizer application, resulting in insufficient fertilization amount or even interruption of fertilization. Moreover, when using air flow for fertilization, air flow disturbance easily occurs, causing the fertilizers to be washed away during transportation, resulting in overly dispersed fertilizers and affecting the fertilizer concentration. In addition, the soil in paddy fields has a high viscosity, and existing transplanters cannot well bury the fertilizer grooves after fertilization, resulting in poor soil covering effect and exposure of fertilizers. Summary of the Invention

[0060] Now, the present invention will be further described in 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.

[0061] AsFigures 1 - 15 As shown, a rice transplanter with a synchronous fertilization structure comprises: a rice transplanter body 1, a load table 2 installed on the side of the driving position of the rice transplanter body 1, a fertilizer storage barrel 3 installed on the load table 2, a fertilizer transfer device 4 arranged on the rice transplanter body 1 and connected to the fertilizer storage barrel 3, and a fertilizer backfilling part 5 arranged on the fertilizer transfer device 4;

[0062] The fertilizer backfilling part 5 is close to a plurality of planting claws of the rice transplanter body 1 from the rear side, wherein:

[0063] The fertilizer conveying device 4 is suitable for drawing the fertilizer in the fertilizer storage barrel 3 outward and conveying it horizontally, so that the fertilization width covers the transplanting range of the rice transplanter body 1;

[0064] The fertilization backfilling part 5 is driven to be obliquely inserted into the paddy field and the fertilizer is quantitatively guided from the fertilizer conveying device 4 to deliver the fertilizer to the root system of the seedlings;

[0065] The fertilizer backfilling part 5 is suitable for closing the soil around the fertilizer to cover the fertilizer. The rice transplanter with a synchronous fertilization structure can transport the fertilizer in a different direction through the fertilizer conveying device 4, so that the fertilizer width can cover the entire planting width, and the comprehensive fertilization can be ensured while streamlining the structure. The fertilizer backfilling part 5 can smoothly apply the fertilizer to the root system of the seedlings. At the same time, the fertilizer backfilling part 5 supports the application of fertilizer by inserting it into the soil and temporarily forming a fence in the soil, and avoids the contact between the fertilizer outlet and the moist soil as much as possible, thereby effectively preventing the fertilizer from sticking to the fertilizer outlet and causing the fertilizer outlet to be blocked or causing insufficient fertilizer to be applied, resulting in insufficient fertilizer or even interrupted fertilization, preventing fertilization from being affected, and ensuring the continuous effectiveness of fertilization. After the fertilization is completed, the fertilizer backfilling part 5 can immediately push the turned soil from both sides to the original position, so that the soil can be effectively backfilled, ensuring that the turned position is buried, and effectively preventing the fertilizer from being exposed.

[0066] The rice transplanter with a synchronous fertilization structure fertilizes by cyclically opening and disconnecting the fertilizer delivery channel, so that the duration of opening the delivery channel can be accurately controlled, thereby achieving regulation of the fertilization amount;

[0067] The rice transplanter with a synchronous fertilization structure can process the fertilizer during the process of adding fertilizer, disperse the parts of the fertilizer where lumps exist, ensure the looseness of the fertilizer, and effectively prevent the fertilizer from blocking the transportation channel, causing fertilization interruption or affecting the fertilizer efficiency.

[0068] Optionally, the fertilizer conveying device 4 includes two positioning plates 41 symmetrically installed on both sides of the main body 1 of the transplanter, a round tube 42 inserted through one of the positioning plates 41, a protruding column 43 connected to the end of the round tube 42, and the protruding column 43 is inserted through the other positioning plate 41. A auger 44 is rotatably installed in the round tube 42, an external loading platform 45 is connected to the other end of the round tube 42, a first motor 46 is arranged on the external loading platform 45, and the output shaft of the first motor 46 penetrates into the round tube 42 and is connected to the auger 44. A blanking pipe head 47 is vertically communicated with the round tube 42 and is close to the first motor 46. A feeding pipe 48 has one end communicating with the fertilizer storage barrel 3 from the bottom and the other end obliquely downward communicating with the blanking pipe head 47, and a rectangular receiving groove 49 is obliquely connected to the round tube 42;

[0069] A through groove is linearly formed on the side wall of the round tube 42, the rectangular receiving groove 49 covers the through groove, and the feeding pipe 48 conveys the fertilizer in the fertilizer storage barrel 3 into the blanking pipe head 47, so that the fertilizer can reach the inside of the round tube 42. During rice transplanting, the first motor 46 is driven regularly or timely to drive the auger 44 to rotate, and the auger 44 starts to convey the fertilizer. The fertilizer accumulated in the blanking pipe head 47 starts to flow, and as the auger 44 continuously conveys, the fertilizer in the fertilizer storage barrel 3 continuously enters the round tube 42. During the process of the auger 44 conveying the fertilizer, at the through groove on the side wall of the round tube 42, the fertilizer leaks downward into the rectangular receiving groove 49 until the rectangular receiving groove 49 is filled, so as to ensure the sufficiency of the fertilizer in the rectangular receiving groove 49 and guarantee the smooth progress of subsequent fertilization; the auger 44 conveys the fertilizer in a changed direction to ensure that the requirement of the fertilization width is met, and it is ensured that a whole row of rice seedlings can be fertilized. At the same time, it is not necessary to use multiple storage devices to store fertilizers at different positions to ensure that a whole row of rice seedlings can be fertilized, which simplifies the structure.

[0070] Optionally, a cover 6 is installed on the top of the fertilizer storage barrel 3. A feeding port 7 communicating with the inside of the fertilizer storage barrel 3 is arranged on the cover 6. A second motor 8 is installed upside down in the middle of the cover 6, and the second motor 8 penetrates downward through the cover 6. A plurality of beating plates 9 are circumferentially connected to the output shaft of the second motor 8;

[0071] A plurality of the beating plates 9 are close to the end of the feeding port 7;

[0072] Some of the beating plates 9 have a fine mesh inside. When the fertilizer in the fertilizer storage barrel 3 is insufficient, materials are added into the fertilizer storage barrel 3 through the feeding port 7. While adding materials, the second motor 8 is driven to drive some of the beating plates 9 to rotate at high speed, so as to use some of the mesh beating plates 9 to beat the fertilizer flowing down from the feeding port 7, so that the fertilizer is impacted. The loose fertilizer can pass through after contacting some of the mesh beating plates 9, while the caked fertilizer will be forcibly separated, ensuring the looseness of the fertilizer, effectively preventing the fertilizer from blocking the material guiding pipe 48 and other things from causing the interruption of fertilization, or affecting the fertilizer efficiency due to the too large size of the fertilizer block that is not easily dissolved.

[0073] Optionally, the fertilization and backfilling part 5 includes a number of first electric push rods 51 installed at equal intervals on the side surface of the rectangular material receiving groove 49, a long strip plate 52 connected to the output ends of the number of first electric push rods 51, and the long strip plate 52 is in contact with the bottom surface of the rectangular material receiving groove 49. A number of bent and sunken plates 53 are hinged on the long strip plate 52. The number of bent and sunken plates 53 are grouped in pairs, and every two of the bent and sunken plates 53 are aligned and closed towards each other. A number of arc springs 54 with one end connected to the long strip plate 52 and the other end respectively connected to the back surfaces of the number of bent and sunken plates 53, a number of second electric push rods 55 installed on the long strip plate 52 and respectively located in the number of groups of bent and sunken plates 53, a number of flared pipe heads 56 respectively connected to the output ends of the number of second electric push rods 55, and the number of flared pipe heads 56 are respectively centered in the number of groups of bent and sunken plates 53. A number of passage pipes 57 are respectively inserted and slid down on the number of flared pipe heads 56 from top to bottom, a number of right-angle hanging plates 58 installed on the long strip plate 52, a number of third electric push rods 59 respectively arranged on the number of right-angle hanging plates 58 and respectively located in the number of groups of bent and sunken plates 53, and the output ends of the number of third electric push rods 59 are respectively connected to the number of passage pipes 57, and a number of cross-shaped silica gel valves 591 installed on the bottom surface of the rectangular material receiving groove 49, and the number of cross-shaped silica gel valves 591 are respectively aligned with the number of passage pipes 57. The cross-shaped silica gel valve 591 is a kind of existing simple valve, which remains closed under normal conditions and even liquid cannot pass through it. It can be opened under the action of external force. Under normal conditions, the rectangular material receiving groove 49 is kept airtight by the number of cross-shaped silica gel valves 591 to prevent the fertilizer inside from flowing out.

[0074] The lower ends of the number of groups of bent and sunken plates 53 are pointed.

[0075] The gap size below the flared pipe head 56 in the number of groups of bent and sunken plates 53 decreases based on the diameter of the flared pipe head 56.

[0076] Through holes are provided at the positions on the long strip plate 52 corresponding to the number of passage pipes 57.

[0077] The plurality of passage pipes 57 are respectively attached to the plurality of planting claws of the transplanter body 1 from the rear side. When transplanting, when the plurality of planting claws start to plant the seedlings in the front row, the plurality of first electric push rods 51 are driven to push the long strips 52 downward, and the plurality of bent indented plates 53 are inserted into the soil. After the plurality of bent indented plates 53 are pushed to a suitable depth, that is, when the predetermined fertilization depth is reached, the plurality of first electric push rods 51 are stopped from being driven, and then the plurality of second electric push rods 55 and the plurality of third electric push rods 59 are immediately driven to push the plurality of flared pipe heads 56 and the plurality of passage pipes 57 downward and upward at the same time. Since each group of bent indented plates 53 The gap inside is smaller than that of the flared pipe head 56. Therefore, when the flared pipe heads 56 move downward, the corresponding group of bent indented plates 53 are squeezed to both sides. After the bent indented plates 53 are squeezed, the corresponding arc springs 54 are compressed and rotated. Therefore, the closed bent indented plates 53 are gradually opened until each group of bent indented plates 53 is opened to a size similar to the diameter of the plurality of passage pipes 57. At the same time, the plurality of passage pipes 57 push open the plurality of cross silicone valves 591 and insert them into the rectangular receiving trough 49, so that the rectangular receiving trough 49 and the plurality of passage pipes 57 are connected. At this time, the fertilizer in the rectangular receiving trough 49 can pass through the plurality of passage pipes 57. 7 and the plurality of flared pipe heads 56 flow downward into the soil, thereby ensuring that the fertilizer is smoothly applied to the root system of each seedling during transplanting, thereby completing the fertilization; during the fertilization process, the plurality of bent inner recessed plates 53 are inserted into the soil to create a relatively closed space in the soil for the plurality of passage pipes 57 and the plurality of flared pipe heads 56 inside the plurality of bent inner recessed plates 53, thereby enclosing the soil outside, and quickly completing the fertilizer application when the plurality of bent inner recessed plates 53 are opened, thereby avoiding the plurality of flared pipe heads 56 from contacting with the wet soil as much as possible, thereby effectively preventing the plurality of flared pipe heads 56 from being blocked or causing insufficient fertilizer to be applied. Insufficient fertilizer application or even interruption of fertilization can be prevented, fertilization can be prevented from being affected, and the continuous effectiveness of fertilization can be ensured; the diameters of the flared pipe heads 56 are larger than the passage pipes 57, and the bent recessed plates 53 are squeezed open to allow all fertilizers to smoothly reach the roots of the seedlings, while effectively improving the fault tolerance rate; even if soil sticks to the pipe openings of the flared pipe heads 56, there can still be channels for the fertilizer to fall, further preventing the fertilizer application from being affected; allowing the passage pipes 57 to stay longer in the rectangular receiving trough 49 can allow more fertilizer to flow downward, ensuring that the amount of fertilizer can be adjusted to meet different fertilization requirements.

[0078] Optionally, the fertilizer backfilling part 5 further includes a plurality of push scrapers 592 respectively installed on both sides of the plurality of flared pipe heads 56;

[0079] Some of the pushing scrapers 592 are respectively attached to the inner sides of some of the bent and recessed plates 53. After fertilization is completed, the opening sizes of some of the bent and recessed plates 53 are maintained, and some of the first electric push rods 51 are reversely driven to pull some of the bent and recessed plates 53 away from the soil, making them stick to the surface of the soil or slightly inserted into the soil. Subsequently, some of the second electric push rods 55 are driven again to push some of the flared pipe heads 56 downward by a certain distance, so that the openings of some of the bent and recessed plates 53 are enlarged a little to ensure that the just-turned area can be included. Then, some of the flared pipe heads 56 are reset. After some of the bent and recessed plates 53 lose the internal pressure, they gradually return to the closed state under the rebounding action of the corresponding arc springs 54. During the process of some of the bent and recessed plates 53 closing again, the turned soil is pushed together from both sides to the original position to backfill the soil, or the soil beside the fertilization position is pushed to the fertilization place to ensure that the fertilized and turned position is filled, effectively preventing the situation where fertilizers will be exposed; during the repeated fertilization process, some of the flared pipe heads 56 can be pushed downward significantly regularly or timely to expose some of the bent and recessed plates 53, so that during this process, some of the pushing scrapers 592 are used to scrape the inner sides of some of the bent and recessed plates 53, and the soil adhered to some of the bent and recessed plates 53 during fertilization and soil backfilling is cleaned in time to prevent the adhesion of too thick soil from hindering the application of fertilizers, resulting in insufficient fertilizers reaching the roots of the seedlings.

[0080] Optionally, the fertilizer conveying device 4 further includes a third motor 10 installed on the main body 1 of the transplanter, a driving gear 11 installed on the output shaft of the third motor 10, and a driven gear 12 installed on the protruding column 43, and the driving gear 11 and the driven gear 12 are engaged;

[0081] The circular pipe 42 and the protruding column 43 are respectively rotatably installed on two of the positioning plates 41. By driving the third motor 10 and through the meshing transmission of the driving gear 11 and the driven gear 12, the circular pipe 42 and the protruding column 43 can be driven to rotate, so as to adjust the overall angle of the rectangular material receiving groove 49 and the fertilization and backfilling part 5, and further ensure that the fertilization angle can be adjusted at any time according to different transplanting spacings and other situations, ensure the coordinated operation of each link, and improve the adaptability under different operating conditions;

[0082] The part of the material guiding pipe 48 close to the material dropping pipe head 47 is soft, ensuring that when the circular pipe 42 rotates, the soft part of the material guiding pipe 48 can also twist accordingly, ensuring that the fertilizer transportation will not be affected or even interrupted.

[0083] Optionally, elastic sheets 13 are arranged on both the front and back sides of several groups of the bent and recessed plates 53;

[0084] Several of the elastic sheets 13 respectively cover the butt joints on the front and back sides of several groups of the bent and recessed plates 53. When several bent and recessed plates 53 are opened, several elastic sheets 13 are stretched accordingly, always maintaining the integrity of the four sides of several bent and recessed plates 53, preventing a large amount of soil from drilling into several bent and recessed plates 53, resulting in premature backfilling of the soil and insufficient fertilization depth.

[0085] Optionally, several leather sleeves 14 are installed between the long strip plate 52 and several of the bent and recessed plates 53;

[0086] Several of the leather sleeves 14 respectively cover several of the arc springs 54, protecting several arc springs 54 from being splashed by moist soil and adhering to them for a long time, which affects their service life.

[0087] In another embodiment of the present invention, a method for using a transplanter with a synchronous fertilization structure is provided:

[0088] S1: Before starting transplanting, according to the set transplanting spacing and the required fertilization depth, drive the third motor 10 to rotate the round tube 42 until the inclination of the rectangular receiving trough 49 is adjusted to a suitable state;

[0089] S2: Drive the first motor 46 to drive the auger 44 to rotate, and start transporting the fertilizer horizontally. At the same time, the fertilizer in the fertilizer storage barrel 3 continuously enters the round tube 42 through the material guiding pipe 48 and the blanking pipe head 47 and is transported by the auger 44. During the transportation, the fertilizer gradually falls into the rectangular receiving trough 49 through the through slots on the round tube 42 until the rectangular receiving trough 49 is filled with fertilizer;
