Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically to a fertilizer application device for agricultural planting machinery suitable for sandy soil. Background Technology

[0002] Sandy soil refers to soil with a high sand content, coarse particles, rapid water infiltration, poor water retention, and good aeration. Based on these characteristics, sandy soil is suitable for planting crops such as peanuts and corn. In agricultural planting, soil fertilization is necessary, currently mainly achieved through manual spreading and mechanical spreading methods.

[0003] For example, patent CN118140794B discloses a mechanized fertilization device for planting in sandy soil, including a fertilizer box, a connector on the side wall of the fertilizer box, a material-retrieving cylinder fixedly installed on the bottom wall of the fertilizer box, a material-retrieving port on the side wall of the material-retrieving cylinder, a fertilization cylinder below the material-retrieving cylinder, and a positioning mechanism on the bottom wall of the fertilizer box that cooperates with the fertilization cylinder. The positioning mechanism includes a support component and a lifting component. A fertilization mechanism is installed inside the fertilization cylinder. The fertilization mechanism includes a material-retrieving component and a fertilization component. The material-retrieving component includes a sealing part and a material-retrieving part. The fertilization component includes a receiving part and a discharging part. This device solves the problem that currently, fertilizer is directly sprinkled on the soil surface, resulting in poor soil fertility in the deeper layers, insufficient nutrient absorption by crop roots, and poor fertilization effect.

[0004] While this patent solves the problem of poor fertilization effect through the telescopic function of the fertilization component, the inability to freely adjust the height of the fertilization component makes it impossible to adjust the fertilization depth according to different fertilization conditions, causing some inconvenience during use; moreover, the single-hole fertilization efficiency of the fertilization cylinder is also relatively low. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing an agricultural planting machinery fertilization device suitable for sandy soils. It can automatically adjust the fertilization depth according to different fertilization conditions, enabling simultaneous sowing and fertilization operations and greatly improving work efficiency.

[0006] This utility model is achieved through the following technical solution: an agricultural planting machinery fertilization device suitable for sandy soil, comprising a frame, on which a soil covering mechanism and multiple sets of soil breaking and discharging mechanisms are provided. The multiple sets of soil breaking and discharging mechanisms are arranged in a front-to-back direction, with the soil covering mechanism located behind the multiple sets of soil breaking and discharging mechanisms. The soil breaking and discharging mechanism includes a movable frame, a first hydraulic cylinder, a trenching component, and a discharge box. The movable frame is slidably connected to the frame. The first hydraulic cylinder is fixed on the frame and drives the movable frame to slide up and down. The trenching component includes an outer discharge pipe and an inner discharge pipe arranged coaxially. A fastening bolt for tightening the inner discharge pipe is threaded onto the outer discharge pipe. The upper end of the outer discharge pipe is detachably fixed to the lower end of the movable frame. A soil breaking shovel is fixedly connected to the lower end of the outer discharge pipe. The discharge box is fixed on the frame, and the discharge port at the bottom of the discharge box is connected to the upper end of the inner discharge pipe through a conveying hose.

[0007] As an optimization, the movable frame is a rectangular frame composed of two vertical rods and two horizontal rods. Sliding sleeves are fixedly connected to the left and right crossbeams of the frame. The two vertical rods are respectively inserted into the two sliding sleeves. The horizontal rods extend in the left and right direction. The two horizontal rods are located above and below the frame, respectively. The first hydraulic cylinder is set vertically. The telescopic end of the first hydraulic cylinder is fixedly connected to the upper horizontal rod. The external discharge pipe is fixedly connected to the lower horizontal rod.

[0008] As an optimization, two trenching components are provided on the lower crossbar. The outer discharge pipes of the two trenching components are fixed to the crossbar by U-shaped clamps, and the inner discharge pipes of the two trenching components are respectively connected to the discharge box by conveying hoses.

[0009] As an optimization, the soil covering mechanism includes a soil-pressing roller and two support legs. The two support legs are arranged opposite each other and fixed to the rear end of the frame. The soil-pressing roller is rotatably installed between the two support legs.

[0010] As an optimization, a soil covering plate is also fixed to the support leg, and the soil covering plate is located in front of the soil-pressing roller.

[0011] As an optimization, the front end of the frame is provided with a connector for interlocking with the front of the agricultural planting machinery.

[0012] As an optimization, the connector includes a triangular connector and a pin. The triangular connector is fixed to the front end of the frame, and a pin hole adapted to the pin is opened on the front corner of the triangular connector.

[0013] As an optimization, the bottom of the frame is provided with a support member located in front of multiple sets of earth-breaking and material discharge mechanisms. The support member includes a second hydraulic cylinder and a support plate. One end of the second hydraulic cylinder is hinged to the frame, and the support plate is fixed to the other end of the second hydraulic cylinder.

[0014] The beneficial effects of this utility model are as follows: 1. The first hydraulic cylinder can drive the movable frame to move up and down, thereby moving the trenching component up and down to adjust the height. This allows for different fertilization depths to be adjusted according to the fertilization needs of different soil textures and crop varieties. It is more suitable for soft soils such as sandy soils, and is more convenient, flexible and applicable.

[0015] 2. The trenching component adopts a coaxial structure of inner and outer discharge pipes. When the height of the outer discharge pipe is adjusted, the position of the inner discharge pipe can remain unchanged, so that its connection with the discharge box remains unchanged, thereby ensuring the stability of material conveying.

[0016] 3. Two sets of trenching components are installed on the crossbeams of the mobile frame, allowing for the simultaneous trenching of two rows of fertilization, greatly improving work efficiency. Furthermore, the two sets of trenching components are detachable via U-shaped clamps, facilitating adjustment of the lateral spacing between them and allowing for different trenching intervals, thus enhancing operational flexibility.

[0017] 4. The front end of the frame can be connected to the head of an agricultural machinery tractor via a connector, allowing the tractor to pull the machine for fertilization operations. When not in use, it can be stabilized using support components.

[0018] 5. The fertilization device is equipped with multiple sets of soil breaking and material discharging mechanisms. Each set of soil breaking and material discharging mechanisms can be adjusted to different soil breaking depths. Therefore, each set of soil breaking and material discharging mechanisms can apply different materials for sowing, reducing repetitive work processes. After sowing, the soil covering components at the rear cover the soil and compact it, reducing labor and improving work efficiency. Attached Figure Description

[0020] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0021] like Figures 1-5 As shown, an agricultural planting machinery fertilization device suitable for sandy soil includes a frame 1. The frame 1 is equipped with a soil covering mechanism 3 and multiple sets of soil breaking and discharging mechanisms 2. The multiple sets of soil breaking and discharging mechanisms 2 are arranged in the front-back direction, and the soil covering mechanism 3 is located behind the multiple sets of soil breaking and discharging mechanisms 2.

[0022] Specifically, the frame 1 is a rectangular frame consisting of two crossbeams 11 and two side beams 12. The two crossbeams 11 extend in the front-to-back direction and are arranged opposite each other in the left-to-right direction. The two side beams 12 are fixed to the front and rear ends of the two crossbeams 11. In this embodiment, the frame 1 is equipped with three sets of the soil breaking and material discharge mechanisms 2.

[0023] The soil-breaking and material-discharging mechanism 2 includes a movable frame 21, a first hydraulic cylinder 23, a trenching component 22, and a material discharge box 25. The movable frame 21 is slidably connected to the frame 1, and the first hydraulic cylinder 23 is fixed on the frame 1 and drives the movable frame 21 to slide up and down. The trenching component 22 includes an outer discharge pipe 221 and an inner discharge pipe 222 arranged coaxially. A fastening bolt 223 is threadedly connected to the outer discharge pipe 221 to tighten the inner discharge pipe 222. The fastening bolt 223 passes through the outer discharge pipe 221 and tightens the inner discharge pipe 222, thereby fixing the inner discharge pipe 222 and facilitating the adjustment of the position of the outer discharge pipe 221. The upper end of the external discharge pipe 221 is detachably fixed to the lower end of the movable frame 21. The lower end of the external discharge pipe 221 is fixedly connected to a soil-breaking shovel 224. The discharge box 25 is fixed on the frame 1. The discharge port at the bottom of the discharge box 25 is connected to the upper end of the internal discharge pipe 222 through a conveying hose 26.

[0024] Specifically, the movable frame 21 is a rectangular frame composed of two vertical rods 211 and two horizontal rods 212. Sliding sleeves 24 are fixedly connected to the left and right crossbeams 11 of the frame 1. The two vertical rods 211 are respectively inserted through the two sliding sleeves 24. The horizontal rods 212 extend in the left-right direction, and are located above and below the frame 1 respectively. The first hydraulic cylinder 23 is vertically arranged, and its extension end is fixedly connected to the upper horizontal rod 212. The external discharge pipe 221 is fixedly connected to the lower horizontal rod 212.

[0025] In this embodiment, a support beam 13 for supporting the first hydraulic cylinder 23 is fixedly connected between the two crossbeams 11 of the frame 1. The support beam 13 and the crossbar 212 of the movable frame 21 are arranged vertically opposite each other. The first hydraulic cylinder 23 can be a hydraulic jack, which can be purchased directly from the market. The first hydraulic cylinder 23 is fixed between the support beam 13 and the upper crossbar 212. The extension and retraction of the first hydraulic cylinder 23 drives the movable frame 21 to move up and down along the sliding sleeve 24, thereby driving the trenching component 22 to move up and down to adjust the height. This allows for adjustment of different fertilization depths according to different soil textures and crop varieties, making it more convenient, flexible, and applicable.

[0026] In this embodiment, two trenching components 22 are provided on the lower crossbar 212. The outer discharge pipes 221 of the two trenching components 22 are fixed to the crossbar 212 via U-shaped clamps 27, and the inner discharge pipes 222 of the two trenching components 22 are respectively connected to the discharge box 25 via conveying hoses 26. Two sets of trenching components 22 are provided on the crossbeam 11 of the movable frame 21, so two rows of trenches can be opened simultaneously for fertilization, greatly improving work efficiency. Furthermore, the two sets of trenching components 22 are detachable via U-shaped clamps 27, allowing their positions to be adjusted along the length of the crossbar 212 during use, thereby adjusting the lateral spacing between the two sets of trenching components 22, facilitating the adjustment of different trenching spacings and improving operational flexibility.

[0027] The discharge box 25 described in this embodiment has a conical hopper structure, with the smaller diameter end serving as the discharge port for easy material discharge. Furthermore, a quantitative discharge device is installed at the bottom of the discharge box 25 to uniformly and quantitatively discharge fertilizer, ensuring even spreading. This quantitative discharge device is a conventional structure found in the seed boxes of existing agricultural seeders and can be directly used as a replacement; therefore, it will not be described in detail here.

[0028] Specifically, the soil covering mechanism 3 includes a soil-pressing roller 32 and two support legs 31. The two support legs 31 are arranged opposite each other and fixed to the rear end of the frame 1. The soil-pressing roller is rotatably mounted between the two support legs 31. A soil-covering plate 33 is also fixed to the support legs 31, and the soil-covering plate 33 is located in front of the soil-pressing roller 32. This fertilization device is equipped with multiple sets of soil-breaking and material-discharging mechanisms 2. Each set of soil-breaking and material-discharging mechanisms 2 can adjust to different soil-breaking depths. Therefore, each set of soil-breaking and material-discharging mechanisms 2 can apply different materials for sowing, reducing repetitive operations. After sowing, the soil is covered by the soil-covering plate 33 at the rear, and the soil layer is compacted by the soil-pressing roller 32, reducing labor and improving work efficiency.

[0029] Specifically, the front end of the frame 1 is equipped with a connector 5, which is used to interlock with the head of agricultural planting machinery (such as a tractor head or a small tractor head). The connector 5 includes a triangular connecting bracket 51 and a pin 52. The triangular connecting bracket 51 is fixed to the front end of the frame 1, and a pin hole 53 adapted to the pin 52 is opened on the front corner of the triangular connecting bracket 51. In use, the front end of the triangular connecting bracket 51 is inserted into the lock lug at the rear end of the vehicle head, the pin hole 53 of the triangular connecting bracket 51 is aligned with the pin hole 53 of the lock lug of the vehicle head, and the device is locked with the vehicle head by a pin. The device is then pulled by the vehicle head to perform soil breaking and material discharge operations.

[0030] The bottom of the frame 1 is equipped with a support member 4 located in front of multiple sets of soil-breaking and material-discharging mechanisms 2. The support member 4 includes a second hydraulic cylinder 41 and a support plate 42. One end of the second hydraulic cylinder 41 is hinged to the frame 1, and the support plate 42 is fixed to the other end of the second hydraulic cylinder 41. In this embodiment, the second hydraulic cylinder 41 can be a hydraulic jack, which can be purchased directly from the market. The second hydraulic cylinder 41 is rotatable. When fertilizing, the second hydraulic cylinder 41 is rotated upwards to retract, avoiding bumps that may affect the operation. To ensure the stability of the support member 4 after it is retracted, a limit mechanism is provided on the frame 1 to fix the retracted support member 4. For example, a hook can be installed on the frame 1 to hold the support member 4 after it is retracted. When not in use, the support member 4 is released to make the second hydraulic cylinder 41 vertical. The second hydraulic cylinder 41 can adjust its support height to support and stabilize the frame 1, facilitating storage.

[0031] Working Principle: During use, the frame 1 is interlocked with the machine head via the connector 5, and the support 4 is retracted. When simultaneous sowing and fertilization operations are required, three sets of soil-breaking and material-discharging mechanisms 2 can be used simultaneously. Personnel sequentially adjust the height of the furrowing components 22 of the three sets of soil-breaking and material-discharging mechanisms 2. During adjustment, the first hydraulic cylinder 23 retracts, causing the movable frame 21 to move downwards, thereby moving the furrowing components 22 downwards. For example, the furrowing depths of the three sets of soil-breaking and material-discharging mechanisms 2 can be 5cm, 15cm, and 30cm from front to back. Seeds, chemical fertilizers, and organic fertilizers are placed sequentially in the discharge boxes 25 of the three sets of soil-breaking and material-discharging mechanisms 2 from front to back. The machine head pulls the device forward, and the soil-breaking shovel 224 first creates a loose soil environment, thereby accurately placing different materials onto the corresponding soil layers. Then, the soil is covered by the covering plate 33, while the soil-pressing roller 32 compacts the soil, which is beneficial for the germination of materials (such as seeds) and reduces moisture evaporation.

[0032] Similarly, depending on the usage requirements, such as when only single fertilization or sowing is needed, only one set of soil breaking and material discharge mechanism 2 can be adjusted for operation, while the other two sets remain stationary.

[0033] Similarly, depending on the usage requirements, such as when only fertilization or sowing is needed, only one set of soil breaking and material discharge mechanisms can be adjusted for operation, while the other two sets remain stationary.

[0034] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model. This utility model has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model do not depart from the spirit of this utility model and should also fall within the protection scope of the claims of this utility model.
