Description

Technical Field

[0001] This utility model belongs to the field of agricultural technology, specifically a small-scale precision positioning device for applying fertilizer in holes in farmland. Background Technology

[0002] A fertilizer application spotter is a machine that locates and digs out the areas where fertilizer is needed by crops during application. Its main purpose is to improve fertilizer utilization, reduce waste, and increase crop yield through targeted and quantitative fertilization technology. This equipment typically combines advanced mechanical design, sensor technology, and positioning systems to achieve efficient and precise fertilization operations.

[0003] Existing positioning devices are generally located by manually pushing the machine.

[0004] However, during the process of finding the right spot, the planer blade used to dig holes is prone to encountering hard rocks on the ground surface. Existing planer blades are generally fixed on one side of the power source, and encountering hard rocks can easily damage the planer blades, thus having certain limitations.

[0005] To address these issues, those skilled in the art have proposed a small-scale precision positioning device for applying fertilizer in holes in farmland. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a small-scale precision positioning device for applying fertilizer in holes in farmland, thereby resolving issues in existing technologies.

[0007] A small-scale precision positioning device for applying fertilizer in holes in farmland includes a positioning frame, on which a positioning mechanism for fertilizer holes is provided:

[0008] The positioning mechanism includes a planer blade, which is mounted on a positioning frame. The planer blade positions and excavates fertilizer holes at the bottom of the positioning frame.

[0009] The positioning frame is also equipped with a transmission component, which is connected to the planer blade.

[0010] Preferably, a motor is fixedly mounted on the positioning frame, and the output shaft of the motor is connected to the transmission assembly.

[0011] Preferably, the transmission assembly includes a first pulley, a belt strip, and a second pulley. The first pulley is fixedly mounted on the output shaft of the motor, and the second pulley is rotatably mounted on the positioning frame. The first pulley and the second pulley are connected by a belt strip.

[0012] Preferably, a first gear is fixedly mounted on the second pulley, and a first shaft is fixedly mounted on the positioning frame. The first gear is rotatably mounted on one end of the first shaft via a bearing.

[0013] Preferably, a moving gear meshes with the first gear, and a second shaft is fixedly mounted on the moving gear, the second shaft being fixedly connected to the planer.

[0014] Preferably, a first swing arm is rotatably provided at one end of the second shaft, and the other end of the first swing arm is rotatably connected to the first shaft.

[0015] Preferably, a second swing arm is rotatably mounted on the second shaft, and a slide rod is rotatably mounted on the other end of the second swing arm. The positioning frame has a groove for the slide rod to slide.

[0016] Preferably, a fixing block is fixedly provided at one end of the slide rod, the fixing block is slidably disposed inside the groove, and a guide rod is fixedly provided at one end of the fixing block.

[0017] Preferably, a spring is fitted on the surface of the guide rod, one end of the spring abuts against the inner wall of the positioning frame, and the other end of the spring abuts against the fixing block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model allows the operator to manually push the positioning frame inside the farmland to accurately locate fertilizer holes. When locating fertilizer holes, it is necessary to first dig and cut them. Start the motor, and the motor will drive the first pulley to rotate. The first pulley will drive the second pulley to rotate through the belt strip. The second pulley will drive the first gear to rotate. The first gear will drive the moving gear to rotate, thereby driving the planer to accurately locate the fertilizer hole through the moving gear, and then dig it.

[0020] 2. This utility model protects the planer blade by setting a clearance function. When the planer blade encounters a hard object, it will retract under the pressure. The planer blade will press against the second swing arm, causing the second swing arm to slide inside the groove of the positioning frame via the slide rod. In other words, the fixing block compresses the spring inside the groove to make clearance, thereby fully protecting the planer blade. Attached Figure Description

[0038] A moving gear 8 meshes with the first gear 6, and a second shaft 10 is fixedly mounted on the moving gear 8. The second shaft 10 is fixedly connected to the planer 9.

[0039] As attached Figure 1 To be continued Figure 3 As shown: the first gear 6 can drive the moving gear 8 to rotate, and the moving gear 8 will drive the planer 9 to rotate through the second shaft 10.

[0040] One end of the second shaft 10 is rotatably provided with a first swing arm 11, and the other end of the first swing arm 11 is rotatably connected to the first shaft 7.

[0043] As attached Figure 1 To be continued Figure 3 As shown: The second shaft 10 and the slide rod 13 are connected by the second swing arm 12.

[0044] A fixing block 14 is fixedly provided at one end of the slide rod 13. The fixing block 14 is slidably provided inside the groove. A guide rod 15 is fixedly provided at one end of the fixing block 14.

[0049] When the planer blade 9 encounters obstacles such as rocks while digging, in order to protect the planer blade 9, it will retract under the pressure of hitting the hard object. The planer blade 9 will press against the second swing arm 12, causing the second swing arm 12 to slide inside the groove of the positioning frame 1 via the slide rod 13. This causes the fixing block 14 to compress the spring 16 inside the groove to make room, thereby providing sufficient protection for the planer blade 9.
