Description

Technical Field

[0001] The present invention relates to the technical field of fertilization implements, and particularly to a fertilization device for row-ridge planted crops. Background Art

[0002] Fertilization can be divided into base fertilization and topdressing according to different times. Topdressing is the fertilizer applied during the growth process of crops. The ways of topdressing include direct spreading, deep burying fertilization, fertilizing with water irrigation, drip irrigation fertilization, and foliar spraying. The main purpose of topdressing is to make up for the deficiency of base fertilization and meet the nutritional needs of plants in the middle and late stages.

[0003] For example, in the Chinese patent with the publication number CN220986667U and the name "A Seedling-raising Fertilization Device", it includes a trolley; axles, both ends of the bottom of the trolley are rotatably sleeved with axles; traveling wheels, both ends of the axles are fixedly sleeved with traveling wheels; a fertilizer bucket, the top of one end of the trolley is fixedly installed with a fertilizer bucket; a material extraction mechanism, the top of the other end of the trolley is installed with a material extraction mechanism, and the material extraction mechanism is connected to an axle; fertilization pipes, fertilization pipes are installed on both sides of the trolley, and the fertilization pipes are connected to the material extraction mechanism. The fertilizer is placed in the fertilizer bucket. The trolley travels along the space between two rows of seedlings. The traveling wheels drive the axles to rotate, and the axles drive the material extraction mechanism to extract the fertilizer from the fertilizer bucket and flow out through the fertilization pipes for fertilization. The traveling distance of the trolley is in a fixed ratio to the outflow rate of the fertilizer, achieving the purpose of uniform fertilization.

[0004] Although a seedling-raising fertilization device in the above patent is practical and convenient, it also has deficiencies. The above realizes uniform and quantitative fertilization through the traveling of the trolley. During the process of changing from a ridge of crops that has been fertilized to another ridge of crops to be fertilized, the trolley will still extract and fertilize while traveling. However, there are no crops in the interval or turning area between the two ridges, which will cause waste of waste materials. Moreover, if the trolley travels to a section without crops, it will still cause waste of fertilizer. Summary of the Invention

[0005] The purpose of the present invention is to provide a fertilization device for row-ridge planted crops to solve the deficiencies in the above-mentioned prior art.

[0009] Further, a turntable is fixedly connected to the top end of the spiral auger. The turntable is rotatably connected to one end of the first bracket. The cross-sectional area of the turntable is larger than the cross-sectional area of the spiral auger.

[0010] Further, the second linkage assembly includes a first hinge seat, a second hinge seat and a connecting rod. The first hinge seat is horizontally slidably connected to the bottom of the vehicle frame. The second hinge seat is fixedly connected to the side of the sleeve close to the vehicle axle. Two ends of the connecting rod are respectively hinged to the first hinge seat and the second hinge seat. The discharge pipe is fixedly connected to the side of the first hinge seat close to the vehicle axle.

[0011] Further, a guide rod is horizontally provided on each side of the first hinge seat, and two guide grooves are symmetrically and horizontally formed on the vehicle frame. The two guide rods are slidably connected to the two guide grooves in a one-to-one correspondence.

[0012] Further, the trigger assembly includes a connecting block, a swing rod, a rotating shaft, and a baffle. The rotating shaft is rotatably connected inside the discharge pipe.

Through the second linkage assembly, the discharge pipe horizontally slides to the discharge station, and through the trigger assembly, the discharge pipe discharges intermittently, avoiding uneven fertilization. And when driving to a section without crops, the plow blade is lifted to make the discharge pipe leave the discharge station, and the discharge pipe stops discharging. At the same time, the transmission assembly drives the spiral auger to rotate. At this time, the blades of the spiral auger are not attached to the inner wall of the material conveying pipe, and the spiral auger plays a stirring role to stir the fertilizer in the fertilizer tank to avoid fertilizer blockage. The intermittent fertilization and stirring modes can be switched by the downward movement of the plow blade to open a trench, improving the adaptability of the overall device.

Detailed implementation manners

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0029] Please refer to Figures 1-9, a technical solution provided by an embodiment of the present invention: a fertilizing device for ridge planting crops, including a frame 1, a transmission assembly, a first linkage assembly, a second linkage assembly, and a triggering assembly. A vehicle axle 2 is rotatably connected inside the frame 1. A wheel 3 is provided at each end of the vehicle axle 2. A plow blade 15 is vertically slidably connected inside the frame 1. A fertilizer bucket 4 is provided on the frame 1. A spiral auger 6 is movably connected inside the fertilizer bucket 4. A feed pipe 11 is provided at the bottom of the fertilizer bucket 4. A discharge pipe 13 is horizontally slidably connected inside the frame 1. A connecting pipe 12 is provided between the feed pipe 11 and the discharge pipe 13. The discharge pipe 13 has a discharge working position during the moving stroke towards the vehicle axle 2. The transmission assembly receives the drive of the rotation of the vehicle axle 2 to make the spiral auger 6 rotate. The first linkage assembly receives the drive of the downward movement of the plow blade 15 to make the blade of the spiral auger 6 fit against the inner wall of the feed pipe 11, and conveys the fertilizer in the fertilizer bucket 4 into the discharge pipe 13. The second linkage assembly receives the drive of the downward movement of the plow blade 15 to make the discharge pipe 13 horizontally slide to the discharge working position. When the discharge pipe 13 is at the discharge working position, the triggering assembly receives the drive of the rotation of the vehicle axle 2 to make the discharge pipe 13 discharge intermittently.

[0030] As a preferred technical solution, the transmission assembly includes a first bevel gear 21, a second bevel gear 22 meshing with the first bevel gear 21, a rotating rod 10, and a slider 9. The second bevel gear 22 is sleeved on the vehicle axle 2. A second bracket 20 is fixedly connected to the bottom of the frame 1. The first bevel gear 21 is horizontally rotatably connected inside the second bracket 20. The rotating rod 10 passes through the first bevel gear 21. One side of the rotating rod 10 is fixedly connected to the slider 9. The spiral auger 6 is sleeved on the rotating rod 10. A second chute 8 is vertically opened inside the spiral auger 6. The slider 9 is slidably connected inside the second chute 8. Specifically, the first bracket 5 provides an upward supporting force for the first bevel gear 21 and the rotating rod 10. When the frame 1 is running, the vehicle axle 2 is driven to rotate by the wheels 3. The vehicle axle 2 drives the second bevel gear 22 to rotate. Through the meshing transmission with the first bevel gear 21, the rotating rod 10 is driven to rotate. The rotating rod 10 drives the slider 9 to rotate. The peripheral surface of the slider 9 fits against the inner wall of the second chute 8. The slider 9 drives the spiral auger 6 to rotate. Since the gap between the blade of the spiral auger 6 and the inner wall of the fertilizer bucket 4 is too large, the spiral auger 6 can stir the fertilizer in the fertilizer bucket 4 to prevent the fertilizer from clogging and affecting the feeding.

[0031] As a preferred technical solution, the first linkage assembly includes a first bracket 5 and a sleeve 14. The sleeve 14 is vertically slidably connected within the vehicle frame 1. The plow blade 15 is detachably connected within the sleeve 14. The top of the screw auger 6 is rotatably connected to one end of the first bracket 5. The other end of the first bracket 5 is fixedly connected to the sleeve 14. A first chute 7 communicating with the second chute 8 is vertically formed within the screw auger 6, and the rotating rod 10 is slidably connected within the first chute 7. Specifically, when fertilization is required, the sleeve 14 drives the plow blade 15 to move downward for ditch opening, and at the same time drives the first bracket 5 to move downward. The first bracket 5 drives the screw auger 6 to move downward, so that the blades of the screw auger 6 are in contact with the inner wall of the material conveying pipe 11. During the conveying process, the fertilizer will be gradually pushed into the discharge pipe 13 along the path of the blades of the screw auger 6 for fertilization operation. Preferably, the sleeve 14 and the plow blade 15 can be connected by screws and bolts, which is convenient for overhauling and cleaning the plow blade 15. A plurality of jacks are vertically and equidistantly formed on the sleeve 14, and a through hole is formed on the plow blade 15. The relative position between the plow blade 15 and the sleeve 14 can be adjusted according to the depth of the ditch opening to adapt to the ditch opening depths required by different crops.

[0032] As a preferred technical solution, a turntable 29 is fixedly connected to the top end of the screw auger 6. The turntable 29 is rotatably connected to one end of the first bracket 5. The cross-sectional area of the turntable 29 is larger than the cross-sectional area of the screw auger 6. Specifically, the first bracket 5 provides an upward pulling force for the screw auger 6 through the turntable 29 to prevent the screw auger 6 from sliding downward and control the displacement of the screw auger 6 in the vertical direction.

[0033] As a preferred technical solution, the second linkage assembly includes a first hinge seat 17, a second hinge seat 18 and a connecting rod 16. The first hinge seat 17 is horizontally slidably connected to the bottom of the vehicle frame 1. The second hinge seat 18 is fixedly connected to the side of the sleeve 14 close to the axle 2. The two ends of the connecting rod 16 are respectively hinged to the first hinge seat 17 and the second hinge seat 18. The discharge pipe 13 is fixedly connected to the side of the first hinge seat 17 close to the axle 2. Specifically, when the sleeve 14 drives the plow blade 15 to move downward for ditch opening, the sleeve 14 drives the second hinge seat 18 to move downward, and pushes the first hinge seat 17 to slide horizontally towards the axle 2 through the connecting rod 16, so that the discharge pipe 13 moves to the discharge station, facilitating subsequent intermittent and uniform discharging.

[0034] As a preferred technical solution, a guide rod 19 is horizontally provided on both sides of the first hinge seat 17. Two guide grooves 30 are symmetrically and horizontally formed on the vehicle frame 1. The two guide rods 19 are slidably connected to the two guide grooves 30 in a one-to-one correspondence. Specifically, through the cooperation between the guide rod 19 and the guide groove 30, the moving path of the second hinge seat 18 is limited and guided, making the process of the discharge pipe 13 moving to the discharge station more stable.

[0035] As a preferred technical solution, the triggering component includes a connecting block 23, a swing rod 24, a rotating shaft 25, and a baffle 26. The rotating shaft 25 is rotatably connected inside the discharge pipe 13. The baffle 26 is sleeved on the rotating shaft 25. The swing rod 24 is rotatably connected to the side of the discharge pipe 13 close to the axle 2. The swing rod 24 is sleeved on the rotating shaft 25. The connecting block 23 is fixedly connected to one end of the second bevel gear 22. The connecting block 23 is in abutting cooperation with the swing rod 24. Specifically, the axle 2 drives the connecting block 23 to rotate through the second bevel gear 22. When the discharge pipe 13 moves to the discharging station, the connecting block 23 is in abutting cooperation with the swing rod 24, driving the swing rod 24 to rotate. The swing rod 24 drives the baffle 26 inside the discharge pipe 13 to rotate through the rotating shaft 25, opening the discharge pipe 13 for fertilization, and applying the fertilizer into the soil trench opened by the plow blade 15, facilitating the crops to absorb the fertilizer and supplement nutrients. When the discharge pipe 13 is not at the discharging station, the baffle 26 always remains horizontal to block the discharge pipe 13, preventing fertilizer waste during the process of the frame 1 driving to a section without crops.

[0036] As a preferred technical solution, a torsion spring 27 is provided between the swing rod 24 and the discharge pipe 13. The torsion spring 27 is sleeved on the rotating shaft 25. Specifically, when the connecting block 23 is not in abutting contact with the swing rod 24, the torsion spring 27 can drive the swing rod 24 to reverse and reset, making the baffle 26 in a horizontal state to block the discharge pipe 13, enabling intermittent feeding, achieving the purpose of uniform feeding, further preventing fertilizer waste, and making the positioning of the fertilizer more accurate, applying it beside each crop to avoid burning the seedlings.

[0037] As a preferred technical solution, the connecting pipe 12 is a bendable telescopic pipe. Specifically, this setting can adapt to the relative position change between the discharge pipe 13 and the conveying pipe 11.

[0038] As a preferred technical solution, a cylinder 28 is provided on the frame 1. The output end of the cylinder 28 is fixedly connected to the top end of the sleeve 14. Specifically, the plow blade 15 can be driven by the cylinder 28 to move downward for ditch opening operation.

[0039] Working principle: When fertilization is required for the ridge planting crop fertilization device, the cylinder 28 drives the sleeve 14 to drive the plow blade 15 to move downward for ditch opening, and at the same time drives the first bracket 5 to move downward. The first bracket 5 drives the spiral auger 6 to move downward, so that the blades of the spiral auger 6 are in contact with the inner wall of the material conveying pipe 11. When the vehicle frame 1 travels, the wheel 3 drives the axle 2 to rotate, the axle 2 drives the second bevel gear 22 to rotate, and through the meshing transmission with the first bevel gear 21, drives the rotating rod 10 to rotate. The rotating rod 10 drives the slider 9 to rotate, and the peripheral surface of the slider 9 is in contact with the inner wall of the second chute 8. The slider 9 drives the spiral auger 6 to rotate. During the conveying process, the fertilizer will be gradually pushed into the discharge pipe 13 along the path of the blades of the spiral auger 6 for fertilization operation. The sleeve 14 drives the second hinge seat 18 to move downward, and through the connecting rod 16, pushes the first hinge seat 17 to slide horizontally towards the axle 2, so that the discharge pipe 13 moves to the discharge station. The axle 2 drives the connecting block 23 to rotate through the second bevel gear 22. When the discharge pipe 13 moves to the discharge station, the connecting block 23 abuts and cooperates with the swing rod 24, driving the swing rod 24 to rotate. The swing rod 24 drives the baffle 26 in the discharge pipe 13 to rotate through the rotating shaft 25 to open the discharge pipe 13 for fertilization. When the connecting block 23 does not abut against the swing rod 24, the swing rod 24 can be driven to reverse and reset by the torsion spring 27, so that the baffle 26 is in a horizontal state to block the discharge pipe 13, realizing intermittent feeding and achieving the purpose of uniform feeding. And when driving to a section without crops, the plow blade 15 is lifted, so that the discharge pipe 13 leaves the discharge station, the torsion spring 27 drives the swing rod 24 to reverse and reset, so that the baffle 26 is in a horizontal state to block the discharge pipe 13, and the discharge pipe 13 no longer discharges material. At the same time, the blades of the spiral auger 6 are not in contact with the inner wall of the material conveying pipe 11. Since the gap between the blades of the spiral auger 6 and the inner wall of the fertilizer bucket 4 is too large, the spiral auger 6 can stir the fertilizer in the fertilizer bucket 4 to avoid fertilizer blockage and affect feeding. The intermittent fertilization and stirring modes can be switched by the downward movement of the plow blade 15 for ditch opening, improving the adaptability of the overall device.

[0040] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
