Description

Technical Field

[0001] The invention relates to the technical field of rice transplanting, and in particular to a side-deep fertilizing device and a rice transplanter. Background Art

[0002] In the field of agricultural production, rice transplanters and side-deep fertilization devices play a key role. As an important agricultural machinery, the rice transplanter is based on the principle of "taking seedlings in groups and planting them directly". The rice seedlings are neatly placed in a seedling box in a group state. The seedling box moves horizontally, and the seedling remover takes a certain amount of seedlings in a certain order. Under the action of the rice transplanting trajectory control mechanism, the seedlings are accurately inserted into the soil according to agronomic requirements. The seedling remover then returns to the seedling box to take the seedlings. This cycle of operation improves rice transplanting efficiency and reduces labor costs. The side-deep fertilization device is a device that completes the fertilization task simultaneously with the rice transplanter. It uses a trenching plate to open a trench next to the seedlings. The fertilizer discharger discharges a certain amount of fertilizer from the fertilizer box, which falls into the trench through a conveying pipe and is then covered by a covering plate. Side-deep fertilization can greatly improve fertilizer utilization. Fertilizer is applied precisely to the soil layer near the roots of the seedlings, reducing volatilization and loss, and avoiding the consumption of fertilizer by weeds and algae, thereby reducing fertilizer usage and alleviating environmental pollution.

[0003] However, the existing technology has the following problems:

[0004] In the current technical application of simultaneous transplanting and fertilizing, although the side-deep fertilization device has realized mechanized fertilization, it still has significant limitations. Most existing devices use a bottom-opening fertilizer discharge structure. When the fertilization device moves in the soil, the soil resists the fertilizer discharge port, causing the soil to wrap and squeeze the fertilizer discharge port, resulting in obstruction of the fertilizer discharge process and difficulty in releasing it evenly and quickly. It can often only be discharged slowly through the gap between the fertilizer discharge port and the soil. As a result, the fertilizer is distributed in long strips in the soil, and the contact range with the seedling roots is limited. Fertilizer far away from the seedlings is difficult to be effectively absorbed and utilized by the roots. Summary of the Invention

[0036] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other implementations obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] In the prior art, during the process of fertilizing while transplanting rice seedlings, although the fertilizer application device can be inserted into the soil to quantitatively release fertilizer, the soil will block the fertilizer discharge port at the bottom of the fertilizer application device as it moves in the soil, so that a batch of fertilizer can only be slowly discharged through the gap between the soil and the fertilizer discharge port. As a result, after the batch of fertilizer enters the soil, it forms a long strip as a whole. The contact range of some fertilizers far away from the seedlings with the seedling roots is limited, the utilization rate is low, and some fertilizers are wasted. This embodiment is specially invented to solve the above problem.

[0039] See also Figure 1 - Figure 5 A side-deep fertilizing device includes: a hopper 2; a fertilizing assembly 3, which is used to apply fertilizer to the soil on one side of the seedlings while transplanting. The fertilizing assembly 3 is installed on the hopper 2. The fertilizing assembly 3 includes a plurality of trenching plates 31, each of which is installed on the hopper 2. A groove 33 is provided in the trenching plates 31. A shifting rod 34 is rotatably installed in the trenching plates 31. The trenching plates 31 can separate the soil to both sides when moving to form a groove. The shifting rod 34 continuously squeezes the fertilizer in the groove 33 when the trenching plates 31 move, thereby pressing the fertilizer into the soil in batches.

[0040] In this embodiment, please refer to Figure 3 - Figure 5 A material pipe 32 is connected to the trenching plate 31, and one end of the material pipe 32 away from the trenching plate 31 is connected to the hopper 2. The hopper 2 is provided with multiple discharge ports, and the multiple discharge ports are respectively connected to the multiple material pipes 32, and the multiple material pipes 32 are respectively connected to the multiple grooves 33. After the fertilizer is loaded into the hopper 2, the fertilizer at the bottom of the hopper 2 enters the multiple material pipes 32 through the multiple discharge ports, and the fertilizer in the material pipes 32 enters the multiple grooves 33 respectively. When the trenching plate 31 moves in the soil, the soil presses against the bottom of the groove 33, so that the groove 33 is filled with fertilizer.

[0041] For further information, see Figure 5, a rebound leaf spring is provided between the lever 34 and the inner wall of the furrowing plate 31, and an accordion rubber strip is provided between the lever 34 and the groove 33. The accordion rubber strip plays a sealing role to prevent some fertilizer from entering the installation area of ​​the lever 34 and getting stuck in the lever 34. A sliding rod 35 is slidably connected to the furrowing plate 31, and the bottom of the sliding rod 35 is in sliding contact with the lever 34. A cylinder 37 is installed on the hopper 2, and the output end of the cylinder 37 is connected to a connecting frame 36. Multiple sliding rods 35 are connected to the connecting frame 36. When the cylinder 37 is started, the connecting frame 36 is driven downward or upward through the output end. The cylinder 37 drives the connecting frame 36 to move downward and upward once, which means that a fertilizing operation is completed. When the connecting frame 36 moves downward, it drives multiple sliding rods 35 to move downward, so that one of them can open Taking the ditch plate 31 as an example, when the slide rod 35 moves downward, it drives the lever 34 in the ditching plate 31 to swing downward. The lever 34 does not block the groove 33 before swinging downward, and the groove 33 is filled with fertilizer. After the lever 34 swings downward, it enters the groove 33 and squeezes the fertilizer in the groove 33 below the lever 34 downward, so that the fertilizer at the bottom of the groove 33 is pressed into the soil, achieving the technical effect of directly pressing a batch of fertilizer into the soil, so that the batch of fertilizer can be more concentratedly distributed next to the seedlings, thereby ensuring that the batch of fertilizer can be effectively absorbed by the seedlings, thereby improving the utilization rate of the fertilizer. After the connecting frame 36 moves upward, it drives multiple slide rods 35 to move upward, and the multiple levers 34 are reset by the elastic force of the rebound leaf spring. Then the fertilizer fills the groove 33 again, ready for the next fertilization operation.

[0042] Also, see Figure 6 A slide 38 is slidably connected in the groove 33, and a return spring is provided between the slide 38 and the groove 33. A dredging rod 39 is connected to the slide 38. A part of the dredging rod 39 is located in the material tube 32. A protruding rod 310 is connected to the dredging rod 39. The protruding rod 310 is located on the motion trajectory of the shifting rod 34. When the shifting rod 34 swings downward, it contacts the protruding rod 310 and drives the protruding rod 310 to move downward. The protruding rod 310 drives the dredging rod 39 and the slide 38 to move downward. After the shifting rod 34 is reset, the slide 38 moves up and resets due to the elastic force of the return spring. The dredging rod 39 and the protruding rod 310 then move upward and reset. When the fertilizer falls in the groove 33, due to the friction and adsorption between the fertilizer particles and the limited space in the groove 33, the fertilizer pushed backward will continuously squeeze the fertilizer in front, causing some fertilizer particles to fit together and stack, gradually reducing fluidity, and then causing blockage in the groove 33, resulting in the fertilizer being unable to fall smoothly. The dredging rod 39 can continuously move the fertilizer up and down through continuous reciprocating motion, thereby promoting the fall of the fertilizer, avoiding fertilizer accumulation and blockage, and ensuring that the fertilization process is not interrupted.

[0043] Example 2

[0044] On the basis of Example 1, after the trenching plate 31 completes fertilizing, the trench formed by the trenching plate 31 still needs to be backfilled manually, which increases the workload and labor costs. This embodiment is specially invented to solve the above problems.

[0045] See also Figure 3 、 Figure 7 - Figure 8 , the soil covering component 4 is used to backfill the trench after the fertilizer is pressed into the soil. The soil covering component 4 is provided with multiple, and the multiple soil covering components 4 are respectively installed on multiple trenching plates 31; the soil covering component 4 includes a soil covering cover 41, which is connected to the trenching plate 31. The soil covering cover 41 has a V-shaped cross section and is tilted. The bottom of the soil covering cover 41 contacts the ground. After the trenching plate 31 forms a trench when it moves, the soil in the trench is turned up to both sides of the trench. The V-shaped cross section of the soil covering cover 41 forms tilted cover walls on both sides. The tilted cover walls on both sides naturally fit with the soil turned up to both sides when the trenching plate 31 is trenching. When the soil cover 41 moves following the trenching plate 31, the soil cover 41 uses the convergence characteristics of the V-shaped structure to guide the soil originally pushed away by the trenching plate 31 to the center of the trench, so that the soil on both sides slides into the trench along the inclined cover wall. The inclined soil cover 41 produces progressive squeezing on the soil during the movement, so that the soil is evenly covered on the fertilizer surface in the trough under the dual effects of gravity and mechanical thrust. The inclined cover wall slightly rolls the backfill soil to fit the soil at the bottom of the trench, avoiding exposure of the fertilizer, achieving the technical effect of automatic soil backfilling, reducing the workload of manual backfilling of the trench, and thus reducing labor costs.

[0046] It is worth mentioning that see Figure 7 - Figure 8 , a sliding column 42 is slidably installed on the soil cover 41, a pressure plate 43 is connected to the bottom of the sliding column 42, a counterweight 44 is connected to the top of the sliding column 42, a pry bar 45 is rotatably installed on the soil cover 41, and a resistance bar 46 is connected to the sliding bar 35. One end of the pry bar 45 abuts against the counterweight 44, and the other end of the pry bar 45 abuts against the resistance bar 46. When the sliding bar 35 moves downward, the resistance bar 46 moves downward, and the resistance bar 46 moves downward to tilt the counterweight 44 upward through the pry bar 45, and the counterweight The weight block 44 drives the sliding column 42 and the pressure plate 43 at the bottom of the sliding column 42 to move upward. When the sliding rod 35 moves upward, it drives the resistance rod 46 to move upward. The counterweight block 44 uses gravity to drive the sliding column 42 and the pressure plate 43 to fall. The pressure plate 43 falls and contacts the soil, thereby compacting the soil. Through the setting of the pressure plate 43, the pressure plate 43 can follow the movement of the soil cover 41. By continuously moving up and then falling, the soil backfilled by the soil cover 41 is compacted again, thereby improving the flatness of the soil.

[0047] Example 3

[0048] On the basis of Example 1, since some fertilizers may clump, after the agglomerated fertilizers enter the discharge port of the hopper 2, the agglomerated fertilizers may cause the material pipe 32 and the groove 33 to be blocked, thereby causing the ditching plate 31 to be unable to perform fertilization operations normally, and then some seedlings may not be effectively fertilized. This embodiment is specially invented to solve the above problems.

[0049] See also Figure 3 、 Figure 9 - Figure 10 , the anti-caking component 5 is used to disperse the fertilizer agglomerated in the hopper 2, and the anti-caking component 5 is installed on the hopper 2; the anti-caking component 5 includes a polished rod 51, the polished rod 51 is movably connected in the hopper 2, multiple groups of fork-shaped pieces 52 are connected to the polished rod 51, and two square rods 53 are connected to the connecting frame 36. The square rod 53 is provided with a corrugated groove 54, and the multiple groups of fork-shaped pieces 52 are respectively located next to the multiple discharge ports of the hopper 2. The two ends of the polished rod 51 respectively pass through the two sides of the hopper 2, and the two ends of the polished rod 51 are respectively slidably connected to the two corrugated grooves 54, and the two corrugated grooves 54 can drive the polished rod when they move. 51 shakes, and the connecting frame 36 drives the two square rods 53 to move up and down when it moves up and down. When the two square rods 53 move up and down, they drive the light rod 51 to shake through the two corrugated grooves 54. When the light rod 51 shakes, it drives multiple groups of fork-shaped pieces 52 to shake. Since the multiple groups of fork-shaped pieces 52 are respectively located at multiple discharge ports of the hopper 2, when the agglomerated fertilizer moves to the discharge port, it contacts a group of fork-shaped pieces 52. The fork-shaped pieces 52 can shake off the agglomerated fertilizer by shaking, so that the agglomerated fertilizer is dispersed and then enters the discharge port, thereby preventing the agglomerated fertilizer from clogging the material pipe 32 and the groove 33.

[0050] Example 4

[0051] See also Figure 1 - Figure 4 , a rice transplanter, including a side-deep fertilizing device in the above embodiment, also includes a frame 1, a hopper 2 is installed on the frame 1, and a driving assembly 6, a seedling tray 7 and an automatic rice transplanting assembly 8 are also provided on the frame 1. The driving assembly 6 is used to drive the frame 1 to travel, and the seedling tray 7 is used to place seedlings. The automatic rice transplanting assembly 8 is used to automatically perform rice transplanting operations when the frame 1 is traveling. The driving assembly 6, the seedling tray 7 and the automatic rice transplanting assembly 8 are all prior art. The automatic rice transplanting assembly 8 uses a seedling taker to take a fixed amount of seedlings from the seedling tray 7 at a set frequency, and is guided by a trajectory control mechanism to accurately insert the seedlings into the soil and then reset the cycle to achieve continuous automatic rice transplanting. Its specific structure and working principle are not described in detail. The rhythm of the extension and contraction of the cylinder 37 cooperates with the automatic rice transplanting assembly 8. When the seedlings are inserted into the soil, the cylinder 37 synchronously drives the connecting frame 36 to move downward, so that the fertilizing assembly 3 presses the fertilizer into the soil next to the seedlings.

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
