[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 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 to the second bracket 20, the rotating rod 10 is penetrated on 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 slide groove 8 is vertically opened in the spiral auger 6, and the slider 9 is slidably connected in the second slide groove 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 traveling, the wheel 3 drives the axle 2 to rotate, and the 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, and the rotating rod 10 drives the slider 9 to rotate. The peripheral side surface of the slider 9 is in contact with the inner wall of the second slide groove 8, and the slider 9 drives the spiral auger 6 to rotate. Since the gap between the blades of the spiral auger 6 and the inner wall of the fertilizer barrel 4 is too large, the spiral auger 6 can stir the fertilizer in the fertilizer barrel 4 to avoid fertilizer blockage and affect material discharge.

[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 to the frame 1, the plow 15 is detachably connected to the sleeve 14, the top of the spiral 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 slide groove 7 communicating with the second slide groove 8 is vertically opened in the spiral auger 6, and the rotating rod 10 is slidably connected to the first slide groove 7. Specifically, when fertilization is needed, the sleeve 14 drives the plow 15 to move downward to dig furrows, and at the same time drives the first bracket 5 to move downward, and the first bracket The frame 5 drives the spiral auger 6 to move downward, so that the blades of the spiral auger 6 fit with the inner wall of the feed pipe 11. During the transportation process, the fertilizer will be gradually pushed into the discharge pipe 13 along the path of the blades of the spiral auger 6 to perform fertilization operations. Preferably, the sleeve 14 and the plow 15 can be connected by screws and bolts to facilitate the inspection and cleaning of the plow 15. A plurality of jacks are vertically opened at equal distances on the sleeve 14, and a through hole is opened on the plow 15. The relative position between the plow 15 and the sleeve 14 can be adjusted according to the depth of the furrowing to adapt to the furrowing depth required for different crops.

[0032] As a preferred technical solution, a turntable 29 is fixedly connected to the top of the spiral auger 6, and 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 spiral auger 6. Specifically, the first bracket 5 provides an upward pulling force for the spiral auger 6 through the turntable 29 to prevent the spiral auger 6 from sliding downward and control the vertical displacement of the spiral auger 6.

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

[0034] As a preferred technical solution, a guide rod 19 is horizontally provided on both sides of the first articulated seat 17, and two guide grooves 30 are symmetrically and horizontally opened on the frame 1. The two guide rods 19 are slidingly connected with 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 articulated seat 18 is limited and guided, so that the process of moving the discharge pipe 13 to the discharge station is more stable.

[0035] As a preferred technical solution, the trigger assembly includes a connecting block 23, a rocker 24, a rotating shaft 25 and a baffle 26. The rotating shaft 25 is rotatably connected to the discharge pipe 13, the baffle 26 is sleeved on the rotating shaft 25, the rocker 24 is rotatably connected to the discharge pipe 13 on one side close to the axle 2, the rocker 24 is sleeved on the rotating shaft 25, the connecting block 23 is fixedly connected to one end of the second bevel gear 22, and the connecting block 23 is abutted against the rocker 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 discharge station, the connecting block 23 abuts against the rocker 24, driving the rocker 24 to rotate. The rocker 24 drives the baffle 26 in the discharge pipe 13 to rotate through the rotating shaft 25, and opens the discharge pipe 13 for fertilization. The fertilizer is applied in the soil ditch opened by the plow 15, which is convenient for crops to absorb fertilizer and supplement nutrition. When the discharge pipe 13 is not at the discharge station, the baffle 26 is always in a horizontal state to block the discharge pipe 13, avoiding fertilizer waste when the frame 1 travels to a section of road without crops.

[0036] As a preferred technical solution, a torsion spring 27 is provided between the rocker arm 24 and the discharge pipe 13, and the torsion spring 27 is sleeved on the rotating shaft 25. Specifically, when the connecting block 23 is not in contact with the rocker arm 24, the rocker arm 24 can be driven by the torsion spring 27 to reverse and reset, so that the baffle 26 is in a horizontal state, and the discharge pipe 13 is blocked, so that intermittent feeding can be realized to achieve the purpose of uniform feeding, further avoid waste of fertilizer, and make the positioning of fertilizer more accurate, so that it can be applied next to each crop to avoid burning seedlings.

[0037] As a preferred technical solution, the connecting pipe 12 is a bendable telescopic pipe. Specifically, this arrangement 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, and the output end of the cylinder 28 is fixedly connected to the top of the sleeve 14. Specifically, the cylinder 28 can be used to drive the plow 15 to move downward to perform a furrowing operation.

[0039] Working principle: When the row ridge crop fertilizer application device needs to apply fertilizer, the cylinder 28 drives the sleeve 14 to drive the plow 15 to move down to open furrows, and at the same time drives the first bracket 5 to move down, and the first bracket 5 drives the spiral auger 6 to move downward, so that the blades of the spiral auger 6 fit the inner wall of the feed pipe 11. When the frame 1 is driving, the wheel 3 drives the axle 2 to rotate, and the axle 2 drives the second bevel gear 22 to rotate, and through the meshing transmission with the first bevel gear 21, the rotating rod 10 is driven to rotate, and the rotating rod 10 drives the slider 9 rotates, and the peripheral side of the slider 9 fits with the inner wall of the second slide groove 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 spiral auger 6 blades to perform the fertilization operation. The sleeve 14 drives the second articulated seat 18 to move downward, and pushes the first articulated seat 17 to slide horizontally toward the axle 2 through the connecting rod 16, so that the discharge pipe 13 moves to the discharge position. 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 position When the connecting block 23 is not in contact with the swing rod 24, the swing rod 24 can be driven to reverse and reset through the torsion spring 27, so that the baffle 26 is in a horizontal state, and the discharge pipe 13 is blocked, so that intermittent feeding can be realized to achieve the purpose of uniform feeding, and when driving to a section without crops, the plow 15 is moved up to make the discharge pipe 13 leave the discharge pipe 13. At the working station, the torsion spring 27 drives the rocker arm 24 to reverse and reset, so that the baffle plate 26 is in a horizontal state, the discharge pipe 13 is blocked, 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 feed pipe 11. Since the gap between the blades of the spiral auger 6 and the inner wall of the fertilizer barrel 4 is too large, the spiral auger 6 can stir the fertilizer in the fertilizer barrel 4 to avoid fertilizer blockage and affect the discharge of the material. The intermittent fertilization and stirring modes can be switched by moving the plow blade 15 downward to open the furrow, thereby improving the adaptability of the overall device.
