Description

Technical Field

[0001] This utility model relates to the field of modern agricultural machinery technology, and more specifically to a multi-functional fertilizer applicator and seeder. Background Technology

[0002] Seeders are modern agricultural machines that can precisely sow seeds into the soil according to specified row spacing, depth, and density, improving sowing efficiency and quality. Multifunctional fertilizer seeders are modern agricultural equipment that integrates fertilization and sowing, and can simultaneously complete processes such as ditching, fertilization, sowing, and soil covering. They can precisely control fertilizer amount, sowing depth, and row spacing, are suitable for a variety of crops, save labor and time, and improve water and fertilizer utilization and planting benefits.

[0003] Traditional fertilizer planters lack an efficient directional soil-gathering structure when covering the soil, causing soil to easily scatter to both sides, resulting in exposed seeds. Furthermore, they lack precise thickness control and synchronous adjustment mechanisms, leading to large deviations in soil thickness and uneven coverage. Their adjustment methods are cumbersome and difficult to quickly adapt to the soil covering requirements of different crops. Frequent replacement of parts is required to adapt to different farming scenarios, which not only reduces operational efficiency but also affects seed germination rates due to poor coverage quality, significantly restricting the adaptability to farming and the stability of output.

[0004] To address this, we propose a multi-functional fertilizer and seeder that enables smooth soil flow, uniform coverage, and precise thickness adjustment. Utility Model Content

[0005] One of the technical problems this application aims to solve is that traditional fertilizer planters have large deviations in soil thickness and uneven coverage when covering the soil, and their adjustment methods are cumbersome and difficult to quickly adapt to the soil covering needs of different crops.

[0009] In some embodiments, two T-shaped sliders are provided on the inner side of the U-shaped sliding plate, and the outer side of the T-shaped sliders is slidably connected to the left side of the guide triangle plate. A connecting soil covering plate is provided at the bottom of the U-shaped sliding plate, and multiple arc-shaped soil combing grooves are opened at the bottom of the connecting soil covering plate.

[0010] In some embodiments, the compaction assembly includes an L-shaped fixing plate, the right side of which is disposed on the left side of the U-shaped mounting bracket, and three sliding posts are disposed at the bottom of the L-shaped fixing plate.

[0011] In some embodiments, a sliding cylinder is slidably connected to the outside of the sliding column, a shock-absorbing spring is sleeved on the outside of the sliding column, the bottom of the shock-absorbing spring is disposed at the top of the sliding cylinder, and a U-shaped fixing bracket is disposed at the bottom of the three sliding cylinders.

[0012] In some embodiments, a compaction wheel is rotatably connected to the inner side of the U-shaped fixing frame, and an annular protrusion is provided on the outer side of the compaction wheel. Three sliding limit plates are provided on the right side of the U-shaped fixing frame, and the right sides of the three sliding limit plates are slidably connected to the left side of the mounting plate.

[0013] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a multi-functional fertilizer and seeding machine, which has the following beneficial effects: 1.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a multi-functional fertilizer planter, including a planter body 1, which provides power output and rigid support for the overall operation. A U-shaped mounting frame 2 is provided on its left side. The U-shaped mounting frame 2 adopts an integrally formed U-shaped steel structure and has stable load-bearing capacity. A mounting plate 3 is provided at its bottom. The mounting plate 3 is a horizontal rectangular steel plate with multiple sets of mounting holes reserved on its surface for component fixing. A soil covering component 4 is provided at its bottom. The soil covering component 4 is the core component for achieving precise soil covering. Multiple flow guiding triangular plates 41 in the soil covering component 4 are set at the bottom of the mounting plate 3. Two adjacent flow guiding triangular plates 41 form a symmetrical isosceles triangular structure. A movable soil covering plate 43 is slidably connected to the outside. The movable soil covering plate 43 can slide vertically along the flow guiding triangular plates 41. A flow guiding inclined plate 45 is set at its bottom. The flow guiding inclined plate 45 is inclined inward to guide the soil to flow in a directional manner. A compaction component 5 is set on the left side of the U-shaped mounting frame 2. The compaction component 5 is used to compact the ground surface after soil covering. The soil covering component 4 includes a flow guiding triangular plate 41, the tip of which faces the working direction to gather the soil. The bottom of the U-shaped mounting frame 2 is equipped with two electric push rods 42, which are arranged symmetrically to provide a stable linear driving force. The left side of the push rod 42 is located on the right side of the mounting plate 3. The driving end of the electric push rod 42 is detachably connected to the movable soil covering plate 43 via a flange and is located on the top of the movable soil covering plate 43. A connecting plate 44 is provided on the right side of the multiple movable soil covering plates 43, which can realize the synchronous linkage of multiple movable soil covering plates 43. A U-shaped sliding plate 46 is provided on the left side of the connecting plate 44. The U-shaped sliding plate 46 has a groove structure and is used to connect the T-shaped slider 49 and the connecting soil covering plate 47. Two T-shaped sliders 49 are provided on its inner side. The T-shaped sliders 49 are adapted to the groove of the guide triangle plate 41 and play a guiding and limiting role. Its outer side is slidably connected to the left side of the guide triangle plate 41. The connecting soil covering plate 47 is provided at the bottom of the U-shaped sliding plate 46. The connecting soil covering plate 47 and the guide inclined plate 45 work together to form a soil covering channel. Multiple arc-shaped soil combing grooves 48 are opened at the bottom. The arc-shaped soil combing grooves 48 are evenly distributed in an array, which can prevent soil from accumulating or scattering at the outlet, so that the soil is evenly spread on the seed surface in the form of a thin layer of coverage. The arc-shaped structure can reduce soil adhesion and ensure the continuity of operation.

[0020] Example 2: Please refer to Figure 1 and Figure 5 The compaction component 5 includes an L-shaped fixing plate 51, which is a bent structure that provides stable installation support. Its right side is located on the left side of the U-shaped mounting bracket 2. The bottom of the L-shaped fixing plate 51 is provided with three sliding columns 52. The three sliding columns 52 are evenly distributed to ensure balanced force. A sliding cylinder 53 is slidably connected to its outside. The sliding cylinder 53 is clearance-fitted with the sliding column 52 to realize up and down telescopic movement. A shock-absorbing spring 54 is sleeved on the outside of the sliding column 52. The shock-absorbing spring 54 is a compression spring that provides elastic buffering force. The bottom of the shock-absorbing spring 54 is set at the top of the slide cylinder 53. The bottom of the three slide cylinders 53 is equipped with a U-shaped fixing frame 55, which is used to support the compaction wheel 57. The compaction wheel 57 is rotatably connected to its inner side. The compaction wheel 57 can roll freely around the axis to realize the surface compaction operation. The outer side is equipped with annular protrusions 58, which are evenly distributed around the circumference of the compaction wheel 57 to enhance the compaction effect and guide soil flow. Three sliding limit plates 56 are set on the right side of the U-shaped fixing frame 55. The three sliding limit plates 56 are arranged vertically in parallel to limit the lateral displacement of the compaction wheel 57. The right side of the plate is slidably connected to the left side of the mounting plate 3 to limit and ensure the stable operation of the compaction wheel 57.

[0021] Based on the above embodiments, the following is the complete working principle of the above embodiments: The soil covering component 4 is fixed to the bottom of the U-shaped mounting frame 2 by the mounting plate 3. Multiple guide triangular plates 41 are evenly arranged along the length of the mounting plate 3 to form multiple independent soil guiding channels. Their tips face the working direction to ensure that the soil can smoothly flow into the sowing row along the inclined surface of the triangular plates. Two electric push rods 42 set at the bottom of the U-shaped mounting frame 2 provide power for adjusting the soil covering thickness. The fixed end of the electric push rod 42 is rigidly connected to the right side of the mounting plate 3, and the driving end is fixed to the top of the movable soil covering plate 43. Multiple movable soil covering plates 43 are synchronously linked through the connecting plate 44. When the electric push rod 42 extends or retracts, it drives the movable soil covering plate 43 to slide along the outside of two adjacent guide triangular plates 41, thereby adjusting the distance between the bottom guide inclined plate 45 of the movable soil covering plate 43 and the ground surface, so as to achieve precise control of the soil covering thickness. The triangular structure of the guide triangle plate 41 gathers the soil in contact with the seeding row in the middle during the operation, preventing the soil from scattering to both sides. The guide slope plate 45 at the bottom of the movable soil covering plate 43 is set at an inclination, guiding the gathered soil to evenly cover the seed surface, forming a continuous soil covering layer. At the same time, the multiple arc-shaped combing grooves 48 opened at the bottom of the connecting soil covering plate 47 move with the mechanism to prevent the soil from accumulating or scattering at the outlet, so that the soil is evenly spread on the seed surface in the form of a thin layer of coverage. The arc structure can reduce soil adhesion and ensure the continuity of operation. The two T-shaped sliders 49 on the inner side of the U-shaped sliding plate 46 form a sliding fit with the sliding surface on the left side of the guide triangle plate 41, providing a guide limit for the lifting and lowering adjustment of the movable soil covering plate 43, preventing deviation or jamming during the adjustment process, ensuring that all movable soil covering plates 43 are lifted and lowered synchronously, and ensuring that the soil covering thickness is consistent across the entire width. The compaction component 5 is rigidly connected to the left side of the U-shaped mounting bracket 2 via an L-shaped fixing plate 51. Located behind the soil covering component 4, it ensures immediate compaction after soil covering is completed, preventing soil moisture loss. Three sliding columns 52 at the bottom of the L-shaped fixing plate 51 slide against the sliding cylinder 53. A damping spring 54 fitted around the sliding columns 52 provides elastic cushioning during compaction. When the ground surface undulates, the compaction wheel 57 is pushed by the surface force or gravity, causing the sliding cylinder 53 to slide up and down along the sliding columns 52. The damping spring 54 extends and retracts synchronously. The release and absorption of elastic potential energy ensures that the compaction wheel 57 remains in contact with the ground surface, achieving adaptive contouring for complex terrain and ensuring consistent compaction depth across the entire field. The compaction wheel 57, rotatably connected to the inner side of the U-shaped fixing frame 55, rolls synchronously with the movement of the entire machine. The annular protrusions 58 on its outer side increase the contact pressure with the soil, improving the compaction effect. At the same time, the gaps between the annular protrusions 58 can guide excess soil squeezed out during compaction to both sides, preventing soil from accumulating above the planting rows and forming ridges, thus ensuring surface flatness. Three sliding limit plates on the right side of the U-shaped fixing frame 55... 56 engages with the sliding surface on the left side of the mounting plate 3 to limit the lateral displacement of the compaction wheel 57, ensuring that the compaction wheel 57 always aligns directly above the sowing row. Simultaneously, the auxiliary slide cylinder 53 moves vertically up and down along the sliding column 52 to prevent uneven compaction caused by tilting. The soil covering component 4 is located at the front of the operation, first completing soil diversion, breaking up, and covering. The compaction component 5 follows closely behind to compact the soil, forming a seamless continuous operation, improving work efficiency and quality. The driving power of the seeder body 1 is converted into the soil guiding force and combing force of the soil covering component 4 and the rolling force of the compaction component 5. The electric push rod 42... The driving force is transmitted to all movable soil covering plates 43 through the connecting plate 44 to achieve synchronous adjustment. The elastic force of the damping spring 54 and the gravity of the compaction wheel 57 form a dynamic balance, which ensures the compaction effect while avoiding excessive pressure that could damage the soil structure. The extension and retraction adjustment of the electric push rod 42 can quickly adapt to the soil covering thickness requirements of different crops. The elastic buffer structure of the compaction component 5 can adapt to the undulation of the ground and different soil hardness. The two work together to achieve multi-functional operation with adjustable soil covering thickness and adaptive compaction effect, which can meet the needs of various farming scenarios without replacing the core components.
