Description

Technical Field

[0001] This application relates to the field of agricultural technology, specifically to a small medicinal herb fertilizer spreader. Background Technology

[0002] In the field of small-scale medicinal herb cultivation, such as ginseng cultivation, small-scale medicinal herb fertilizer spreaders have become one of the core operating equipment to improve fertilization efficiency and reduce manual labor intensity. However, existing small-scale medicinal herb fertilizer spreaders suffer from clogging problems in actual operation. The fertilizer inlets of existing fertilizer boxes generally adopt an elliptical structure. The cross-sectional shape of this structure is extremely unsuitable for impurities and damp fertilizer. When impurities such as stones and soil particles are mixed into the fertilizer, or when the fertilizer clumps or becomes damp and sticky due to high ambient humidity, the narrow area of ​​the elliptical fertilizer inlet is easily blocked, directly causing fertilization interruption. This requires frequent manual shutdowns for cleaning, which not only increases labor costs but also leads to uneven fertilization and differences in the growth of medicinal herbs in missed areas. Utility Model Content

[0003] To address the shortcomings of existing technologies, this application provides a small-scale medicinal herb fertilizer spreader, which solves the technical problem of limited fertilizer discharge from the outlet.

[0004] This application provides a small-scale medicinal herb fertilizer spreader, including: A frame, with wheels at both ends; Fertilizer bins are mounted on the frame; The engine is mounted on the frame; The gearbox is mounted on the frame and is powered by the engine. The gearbox is driven by the walking wheels via a chain drive mechanism; The fertilizer box has a discharge port at the bottom, and a reamer is installed inside the fertilizer box. The reamer is located near the discharge port, and the discharge port is square in shape.

[0005] In the small medicinal herb fertilizer spreader provided in this application, the reamer includes a blade and a cutter shaft. The cutter shaft passes through the two end side walls of the fertilizer box and is rotatably connected to the side walls of the fertilizer box. The blade is fan-shaped, and the cutter shaft is driven by the gearbox.

[0006] In the small medicinal herb fertilizer spreader provided in this application, the interior of the walking wheels is hollowed out.

[0007] In the small medicinal herb fertilizer spreader provided in this application, the frame is made of multiple square tubes and multiple round tubes connected together.

[0008] In the small medicinal herb fertilizer spreader provided in this application, an installation frame is formed in the middle of the frame, the fertilizer box is installed in the installation frame, and two walking wheels are arranged on opposite sides of the fertilizer box.

[0009] In the small medicinal herb fertilizer spreader provided in this application, the engine is located on one side of the fertilizer box and in the middle of the frame. The gearboxes are respectively provided on both sides of the engine. One gearbox is used to drive the walking wheel, and the other gearbox is used to drive the reamer to rotate.

[0010] In the small medicinal herb fertilizer spreader provided in this application, the pulley of the engine and the drive shaft of the gearbox are in a straight line, so that the pulley and the drive shaft are connected together.

[0011] In the small medicinal herb fertilizer spreader provided in this application, the gearbox driving the reamer has a 45-degree angle with the horizontal plane with the reamer as the reference point, so that after the gearbox and the reamer are connected, the connection between the gearbox and the reamer remains stable.

[0012] After the engine starts, it outputs power, which is directly transmitted to the gearbox on the frame. The gearbox converts the power into driving torque for the wheels via a chain drive mechanism, causing the wheels to rotate and enabling the entire fertilizer spreader to move stably along the medicinal herb planting area. At the same time, the medicinal herb-specific fertilizer stored in the fertilizer tank moves towards the bottom discharge port under its own gravity. Meanwhile, the reamers located near the discharge port in the fertilizer tank operate synchronously to loosen and stir the fertilizer, preventing it from clumping, and actively push the loosened fertilizer to the square discharge port. Finally, the fertilizer is evenly discharged through the square discharge port, completing the precise fertilization operation for the medicinal herbs.

[0013] The square discharge port has no narrow dead corners, allowing impurities such as stones and soil particles to be discharged smoothly with the fertilizer. Damp and clump-forming fertilizer can also pass through the square channel after being loosened by the reamer, avoiding frequent manual shutdowns for cleaning, ensuring the continuity of fertilizer spreading operations, and reducing labor costs.

[0014] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0023] In the field of small-scale medicinal herb cultivation, small-scale medicinal herb fertilizer spreaders have become one of the core operating equipment to improve fertilization efficiency and reduce manual labor intensity. However, existing small-scale medicinal herb fertilizer spreaders suffer from clogging problems in actual operation. The fertilizer inlets of existing fertilizer boxes generally adopt an elliptical structure. The cross-sectional shape of this structure is extremely unsuitable for impurities and damp fertilizer. When impurities such as stones and soil particles are mixed into the fertilizer, or when the fertilizer clumps or becomes damp and sticky due to high ambient humidity, the narrow area of ​​the elliptical fertilizer inlet is easily blocked, directly causing fertilization interruption. This requires frequent manual shutdowns for cleaning, which not only increases labor costs but also leads to uneven fertilization and differences in the growth of medicinal herbs in missed areas.

[0024] This application provides a small medicinal herb fertilizer spreader, see reference. Figures 1-3 The small medicinal herb fertilizer spreader includes: a frame 10 with wheels 20 at both ends; a fertilizer bin 50 mounted on the frame 10; an engine 30 mounted on the frame 10; and a gearbox 40 mounted on the frame 10 and connected to the engine 30. The gearbox 40 is driven by the wheels 20 via a chain drive mechanism. The fertilizer bin 50 has a discharge port 501 at its bottom and a reamer 502 inside. The reamer 502 is located near the discharge port 501, which is square in shape.

[0025] After the engine 30 starts, it outputs power, which is directly transmitted to the gearbox 40 on the frame 10. The gearbox 40 converts the power into the driving torque of the walking wheels 20 through the chain transmission mechanism, causing the walking wheels 20 to rotate, so that the entire fertilizer spreader can move stably along the medicinal herb planting area. At the same time, the medicinal herb-specific fertilizer stored in the fertilizer box 50 moves towards the bottom discharge port 501 under its own gravity. Meanwhile, the reamer 502 set in the fertilizer box 50 near the discharge port 501 operates synchronously to loosen and stir the fertilizer, preventing it from clumping, and actively pushes the loosened fertilizer to the square discharge port 501. Finally, the fertilizer is evenly discharged through the square discharge port 501, completing the precise fertilization operation of the medicinal herbs.

[0026] The square discharge port 501 has no narrow dead corners in its channel cross section, allowing impurities such as stones and soil particles to be discharged smoothly along with the fertilizer. Damp and clump-forming fertilizer can also pass through the square channel after being loosened by the reamer 502, avoiding frequent manual shutdowns for cleaning, ensuring the continuity of fertilizer spreading operations, and reducing labor costs.

[0027] In some embodiments, the reamer 502 includes a blade and a cutter shaft, the cutter shaft passing through the two end side walls of the fertilizer tank 50 and being rotatably connected to the side walls of the fertilizer tank 50, the blade being fan-shaped, and the cutter shaft being drivenly connected to the gearbox 40.

[0028] After the engine 30 is started, the gearbox 40 transmits power to the cutter shaft through gears and chains, causing the cutter shaft to rotate stably around its own axis. The blades are designed to be longer (compared to the original short blades). As the cutter shaft rotates, the blades break up the clumps of fertilizer in the fertilizer box 50 through the arc-shaped blade surface. At the same time, because the length of the blades covers the lower area of ​​the fertilizer box 50, they can fully stir the lower layer of fertilizer, preventing fertilizer from accumulating at the bottom of the box. At the same time, the loose and uniform fertilizer is actively pushed to the square fertilizer outlet at the bottom of the fertilizer box 50, forming a continuous operation process of "crushing-stirring-pushing".

[0029] The extended blades can reach the lower layer of fertilizer in the fertilizer bin, avoiding the local accumulation and blockage caused by the original short blades not being able to mix the lower layer of fertilizer. Combined with the square fertilizer inlet, it achieves double anti-blockage and ensures continuous fertilizer dispensing. The combination of fan-shaped blades and an extended design improves the efficiency of breaking up clumps of fertilizer and ensures that the fertilizer is evenly distributed within the container, avoiding fluctuations in fertilizer application due to uneven distribution and guaranteeing the quality of fertilization in medicinal herb fields.

[0030] In some embodiments, the interior of the traveling wheel 20 is hollowed out. The traveling wheel 20 is made of stainless steel with a triangular wheel shape and a hollow structure in the middle of the wheel body. Two symmetrical support points are set in the hollow area to ensure the strength of the wheel body. The traveling wheel 20 is installed at both ends of the frame 10 via axles. The power is generated by the engine 30 driving the 13th gear of the right gearbox 40, which is transmitted through a chain to the 25th gear of the traveling wheel 20. At the same time, two 13th gears are set on the right side of the frame 10 to achieve front and rear drive, driving the traveling wheel 20 to rotate. During operation, the triangular wheel increases the contact friction with the ground, the hollow structure reduces soil adhesion, and the two support points distribute the weight of the wheel body to avoid wheel deformation, ultimately enabling the fertilizer spreader to move stably on complex terrains such as hillsides.

[0031] The stainless steel triangular wheel improves grip, and the front and rear drive design allows the fertilizer spreader to travel on steep hillsides, solving the problem that the original large fertilizer spreader could not operate on hillsides. The hollow structure reduces the weight of the walking wheels by 20 kg, and the triangular wheel strips distribute the ground pressure, preventing the medicinal herb field from collapsing or compacting. This solves the problem of the original mechanical turning damaging the medicinal herb field, and eliminates the need for manual backfilling.

[0032] In some embodiments, the frame 10 is constructed by connecting multiple square tubes and multiple round tubes. The frame 10 is constructed by combining and connecting multiple square tubes and round tubes, with key parts welded and fixed, and detachable parts bolted. The square tubes are mainly used to construct the load-bearing frame of the frame 10, such as the central mounting frame 503 and the engine 30 mounting bracket. The round tubes are used to connect auxiliary parts such as the mounting brackets of the traveling wheels 20 and the support seats of the gearbox 40. The engine 30, gearbox 40, and fertilizer tank 50 are all symmetrically installed on the frame 10. For example, the engine 30 is fixed in the middle of the frame 10, and the pulley of the engine 30 and the drive shaft of the gearbox 40 must be strictly in a straight line before installation. The frame 10, through the combination and symmetrical layout of square and round tubes, bears the weight of all components such as the fertilizer tank 50, engine 30, and gearbox 40, while ensuring that each component is in the optimal stress position.

[0033] In some embodiments, a mounting frame 503 is formed in the middle of the frame 10, the fertilizer bin 50 is installed in the mounting frame 503, and two wheels 20 are arranged on opposite sides of the fertilizer bin 50.

[0034] A mounting frame 503, adapted to the shape of the fertilizer box 50, is formed by welding square tubes in the middle of the frame 10. The fertilizer box 50 is embedded in and fixed to the mounting frame 503 with bolts to ensure that the fertilizer box 50 does not shake when the equipment moves and the cutter shaft rotates. Two traveling wheels 20 are respectively set on opposite sides of the fertilizer box 50. The axles of the traveling wheels 20 are connected to the sides of the mounting frame 503, and the wheel spacing is adapted to the row spacing of the ginseng bed in the medicinal herb field. During operation, the traveling wheels 20 rotate under the drive of the front and rear. Because the wheels are located on both sides of the fertilizer box 50 and adopt a triangular wheel strip and hollow design, they can move along the gaps in the ginseng bed to avoid crushing the ginseng seedlings. At the same time, the mounting frame 503 supports the fertilizer box 50, so that the square fertilizer outlet maintains a stable height with the ground and ensures that the fertilizer spreading width is consistent with the original large machinery.

[0035] In some embodiments, the engine 30 is disposed on one side of the fertilizer box 50 and located in the middle of the frame 10. Gearboxes 40 are respectively provided on both sides of the engine 30. One gearbox 40 is used to drive the walking wheel 20, and the other gearbox 40 is used to drive the reamer 502 to rotate.

[0036] The pulley of engine 30 and the drive shaft of gearbox 40 are in a straight line, so that the pulley and the drive shaft are connected together.

[0037] The above settings enable the device to be symmetrical overall and have a balanced weight distribution.

[0038] In some embodiments, the gearbox 40 driving the reamer 502 forms a 45-degree angle with the horizontal plane with the reamer 502 as the reference point, ensuring a stable connection between the gearbox 40 and the reamer 502 after they are driven together. With the plane containing the axis of the reamer 502 as the reference horizontal plane, the gearbox 40 driving the reamer 502 is installed at a 45° angle to this reference horizontal plane, and the drive shaft of the gearbox 40 and the gear of the reamer 502 must maintain a straight-line configuration. This 45° angle combined with the straight-line configuration ensures uniform transmission clearance between the gearbox 40 and the reamer 502, preventing poor gear meshing due to angular deviations and avoiding gear skipping.

[0039] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
