Description

Technical Field

[0001] This utility model relates to the field of apple planting technology, specifically to a fertilization device for apple planting. Background Technology

[0002] In large-scale apple cultivation, the precision and efficiency of fertilization directly affect the nutrient absorption efficiency of fruit trees and fruit quality. Currently, there are significant technical bottlenecks in the fertilization process of small and medium-sized apple orchards: traditional manual fertilization is labor-intensive and inefficient, making it difficult to meet the needs of large-scale cultivation; while large-scale fertilization equipment can improve efficiency, it is bulky, expensive, and cannot be adapted to the narrow row spacing and complex terrain of small and medium-sized orchards.

[0003] To improve this situation, technological improvements have emerged in related fields. For example, Chinese patent CN220606549 discloses an apple planting fertilization device, which solves the problems of difficult distance control and root burn associated with traditional fertilization methods by using a fixed-distance fertilization component, and prevents dry fertilizer from clumping and clogging through a discharge anti-clogging tapping component. However, this device still has some shortcomings in practical applications: 1. Lacking fertilizer mixing and homogenization mechanisms, it can only be used with single dry fertilizers, which cannot meet the application needs of modern apple cultivation for multi-nutrient fertilizers such as water-fertilizer mixtures and granular fertilizer suspensions. Such mixed fertilizers are prone to stratification if they are not stirred, resulting in uneven nutrient concentration. 2. The adjustment of the fertilization range is limited to the longitudinal distance (distance from the trunk) and does not involve the adjustment of the lateral width. When facing fruit tree row spacing of 1.5-3 meters, it is easy to miss or apply fertilizer repeatedly. 3. The fertilization action and the movement power are not coordinated, and the material discharge needs to rely on an independent drive source, which increases energy consumption and reduces the continuity of operation.

[0004] Therefore, there is an urgent need to develop a specialized fertilization equipment that is suitable for small and medium-sized apple orchards, can accommodate a variety of fertilizers, has an adjustable width, and is energy-efficient. Utility Model Content

[0005] The purpose of this invention is to provide a fertilization device for apple cultivation, which solves the problems mentioned in the prior art in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fertilization device for apple cultivation, comprising a hand-pushed flatbed cart, a storage tank mounted on the hand-pushed flatbed cart, a stirrer mounted inside the storage tank, a first drive mechanism mounted at the bottom of the hand-pushed flatbed cart and driven by its axle, a fertilization mechanism mounted on the hand-pushed flatbed cart, and a second drive mechanism; the first drive mechanism is drivenly connected to the stirrer to drive the stirrer to rotate, and the second drive mechanism is drivenly connected to the fertilization mechanism to drive the fertilization mechanism to unfold or retract.

[0007] Furthermore, the first drive mechanism includes a driving helical gear mounted on one of the axles of the hand-pushed flatbed cart and a drive shaft rotatably connected to the bottom of the hand-pushed flatbed cart; the stirring shaft of the agitator is rotatably connected to the bottom of the storage tank and extends to the bottom of the hand-pushed flatbed cart and is connected to a driving helical gear; both ends of the drive shaft are provided with driven helical gears; the driving helical gear and the driving helical gear respectively mesh with two driven helical gears.

[0008] Furthermore, the fertilizer application mechanism includes support seats on both sides of the hand-pushed flatbed cart, support rods horizontally slidably connected to the two support seats, and nozzles respectively located at the ends of the two support rods; both nozzles are connected to the storage tank via telescopic hoses, and water pumps are connected in series on both telescopic hoses.

[0009] Furthermore, the second drive mechanism includes a rotating shaft and two L-shaped rods. The rotating shaft is rotatably connected to the hand-pushed flatbed cart and has a gear at its bottom. One end of each of the two L-shaped rods is horizontally slidably connected to the hand-pushed flatbed cart through a limiting block. Teeth that mesh with the gear are provided on the opposite side of one end of each of the two L-shaped rods. The other end of each of the two L-shaped rods is connected to the other end of each of the two support rods.

[0010] Furthermore, the storage tank is equipped with a feed pipe with a valve.

[0011] Furthermore, the handle of the hand-pushed flatbed cart is provided with a U-shaped bracket that is rotatably connected to the rotating shaft, and the U-shaped bracket is provided with a set screw that cooperates with the rotating shaft.

[0012] Furthermore, the hand-pushed flatbed cart is equipped with a battery for driving the water pump 12.

[0013] This utility model, through its integrated structural design of material storage and mixing, dual drive, and adjustable fertilization, specifically addresses the shortcomings of existing technologies, and its specific beneficial effects are as follows: 1. This utility model, through the combination of storage tank and agitator, can be adapted to various fertilizer types such as solid fertilizer (which needs to be dissolved in advance), water-fertilizer mixture, and granular fertilizer suspension, breaking through the limitation of existing equipment that can only apply dry fertilizer.

[0014] 2. The first drive mechanism of this utility model utilizes the axle power of the hand-pushed flatbed cart to synchronously drive the mixer to rotate, eliminating the need for an additional motor drive. This not only avoids uneven nutrient concentration caused by the stratification of mixed fertilizers, but also reduces the energy consumption and failure risk of independent drive components.

[0015] 3. The second drive mechanism of this utility model can synchronously adjust the lateral spacing of the two nozzles through a transmission structure of rotating shaft, gear and L-shaped rod, which can adapt to the row spacing of apple trees of 1.5-3 meters, solve the problems of missed application and repeated fertilization in existing equipment; and after adjustment, the nozzle position can be locked by the set screw on the U-shaped bracket to ensure the spacing is stable during fertilization and avoid spraying deviation caused by pushing vibration.

[0016] 3. The stirring action of this utility model relies on the axle power of the equipment, and only the water pump needs to be powered by a battery. Compared with the existing equipment with dual independent drive mode for stirring and discharging, energy consumption is reduced. Attached Figure Description

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Figure 1-4 As shown, this utility model discloses a fertilization device for apple planting, suitable for large-scale or scattered fertilization operations in apple orchards. It can realize the coordinated operation of fertilizer mixing and spraying. It mainly consists of five parts: a basic carrier (hand-pushed flatbed cart 1), a material storage and mixing component (storage tank 2, mixer 3), a dual drive mechanism (first drive mechanism, second drive mechanism), a fertilization execution component (sprayer head 10, pipeline), and an auxiliary power supply component (battery 22). Through the coordinated operation of each part, it realizes the integrated operation of pushing and mixing and adjustable spraying, adapting to apple tree planting scenarios with different row spacing, and taking into account portability and energy saving. The details are as follows: The hand-pushed flatbed cart 1 is the installation base and mobile carrier of the entire fertilization equipment. It is made of Q235 carbon steel welded into a rectangular frame with a frame thickness of 3-5mm (to prevent the storage tank from sliding). The overall load-bearing capacity is not less than 200kg (to meet the requirements of the storage tank being full and the equipment's own weight). The four corners of the bottom of the frame are equipped with reinforcing ribs to improve the resistance to deformation and adapt to complex road surfaces such as soft soil and gravel roads in orchards.

[0020] Two metal axles 20 are set in parallel at the bottom of the hand-pushed flatbed cart 1 via bearing seats and deep groove ball bearings. The diameter of the axles 20 is 20-25mm, and both ends are connected to Φ300mm rubber pneumatic wheels (with anti-slip texture) to reduce pushing resistance. The axle 20 on the side closer to the handle 21 is the "power output shaft" and is used to install the active helical gear 4 of the first drive mechanism. The other axle 20 only serves to support walking.

[0021] Two Φ25mm metal handles 21 are welded to one side of the frame of the hand-pushed flatbed cart 1. The handles 21 are arranged at an angle (15°, which is ergonomic and reduces fatigue when pushing), and the ends are covered with anti-slip rubber sleeves. A metal U-shaped bracket 18 is welded to the top of the handle 21. The opening of the U-shaped bracket 18 faces the outside of the equipment and has a central hole.

[0022] The storage and mixing assembly is responsible for storing and mixing fertilizers to ensure uniform fertilizer concentration during application (especially for water-fertilizer mixtures or granular fertilizer suspensions). It consists of a storage tank 2 and a mixer 3.

[0023] The storage tank 2 is made of 304 stainless steel or food-grade PE plastic, with a diameter of 500-600mm, a height of 800-1000mm, and a volume of approximately 150-200L, meeting the fertilization needs of 10-15 apple trees per trip. The tank wall thickness is 3-5mm, and the top is equipped with a removable tank cover for easy cleaning of residual fertilizer inside. The bottom of the tank is fixed to the center of the upper part of the hand-push flatbed trolley 1 with four M10 bolts. Rubber shock-absorbing pads are placed between the bolts and the hand-push flatbed trolley 1 to reduce vibration during pushing. A Φ50mm feed pipe 17 is welded to the tank cover, and a manual ball valve is installed on the feed pipe 17. When the valve is closed, the inside of the tank is sealed (preventing fertilizer spillage or rainwater ingress). When opened, fertilizer can be quickly added through a funnel. It is suitable for various fertilizer types, including solid fertilizer (which needs to be dissolved in advance) and liquid fertilizer.

[0024] The agitator 3 includes a Φ30mm agitator shaft and 3-4 spiral agitator blades (blade thickness 2mm, diameter 300-400mm, gap with tank wall 10-15mm to avoid scratching); the agitator blades are fixed to the middle of the agitator shaft by welding, with the blades tilted at a 30° angle to improve agitation efficiency and ensure no fertilizer deposits at the bottom of the tank. The agitator shaft vertically penetrates the center of the bottom of the storage tank 2, and a double sealing ring and a deep groove ball bearing (sealed bearing) are installed at the penetration point to ensure flexible rotation of the agitator shaft and prevent fertilizer leakage from the penetration point (or a mechanical seal is installed); the lower end of the agitator shaft extends 100-150mm to the bottom of the hand-pushed flatbed trolley 1, and is fixedly connected to a drive helical gear 6 with a module of 2 and 20 teeth by a flat key (keyway specification 6×16mm). The axis of the drive helical gear 6 coincides with the axis of the agitator shaft and is used to receive power from the first drive mechanism.

[0025] The first drive mechanism is powered by the rotation of the axle 20 when the hand-pushed flatbed cart 1 is pushed, eliminating the need for an additional motor to drive the mixer, thus achieving energy saving and consumption reduction. It includes the active helical gear 4, the drive shaft 5, and the driven helical gear 7.

[0026] The driving helical gear 4 is made of 45 steel with heat treatment (hardness HRC28-32), with a module of 2 and 18 teeth. It is fixedly installed in the middle of the "power output shaft" (axle 20 on the side near the handlebar) of the hand-pushed flatbed trolley 1 by a flat key. The end face of the gear is in contact with the shoulder of the axle 20. The gear is limited by a shaft retaining ring to prevent axial movement. When the axle 20 rotates (driven by the traveling wheels when pushing the equipment), the driving helical gear 4 rotates synchronously, serving as the power input end.

[0027] The drive shaft 5 is a Φ25mm No. 45 steel round shaft, the length of which matches the width of the hand-push flatbed trolley 1 (approximately 800-1000mm). A Φ20mm mounting journal is machined at each end of the shaft (for mounting bearings). The drive shaft 5 is horizontally mounted on the bottom of the hand-push flatbed trolley 1 via two vertical bearing seats (model UCP205). The bearing seats are fixed to the bracket welded to the bottom of the hand-push flatbed trolley 1 with M8 bolts. The bracket height is 50-80mm to ensure that the drive shaft 5, the axle 20, and the axis of the stirring shaft are on the same horizontal plane (to ensure the meshing accuracy of the helical gears).

[0028] There are two driven helical gears 7, both of which are 45 steel helical gears with a module of 2 and 22 teeth. They are fixed to the journals at both ends of the drive shaft 5 by flat keys. The inner side of the gear is in contact with the outer ring of the bearing in the bearing housing and is limited by the shaft retaining ring. The driven helical gear 7 on the side closer to the axle 20 meshes perpendicularly with the driving helical gear 4 (meshing center distance 40mm, which conforms to the helical gear transmission center distance formula a=(m (z1+z2)) / 2), and the driven helical gear 7 on the other side meshes perpendicularly with the driving helical gear 6 at the bottom of the stirring shaft.

[0029] The hand-pushed flatbed cart 1 moves, and the rotation of the axle 20 drives the drive helical gear 4 to rotate. Through meshing transmission, this drives the driven helical gear 7 at one end of the drive shaft 5 to rotate, which in turn drives the drive shaft 5 to rotate, thereby driving the driven helical gear 7 at the other end of the drive shaft 5 to rotate. Finally, this drives the drive helical gear 6 to rotate, thereby driving the mixing shaft to rotate, thus achieving the rotation of the mixing blades to mix the fertilizer. The first drive mechanism synchronizes the pushing and mixing actions. The faster the pushing speed (orchard operation speed is usually 0.5-1m / s), the higher the mixing speed (about 30-50r / min), meeting the requirements for fertilizer homogenization.

[0030] The fertilization mechanism is the fertilization execution end, responsible for delivering the fertilizer in the storage tank to the roots of the apple trees. The spraying range can be adjusted through a sliding support rod, including a support base 8, a support rod 9, a nozzle 10, and a pipeline system.

[0031] There are two support bases 8, which are rectangular metal blocks (80×50×30mm in size). They are symmetrically fixed to the upper two sides of the hand-pushed flatbed trolley 1 (100-150mm from the edge of the trolley) by M6 bolts. A rectangular sliding hole of 20×20mm is opened in the center of the support base 8 (matching the cross section of the support rod 9). The inner wall of the sliding hole is pasted with a polytetrafluoroethylene wear-resistant layer (to reduce sliding friction and extend service life) to ensure that the support rod 9 can slide smoothly horizontally.

[0032] There are two support rods 9, which are 20×20mm aluminum alloy square rods (lightweight and high strength) with a length of 600-800mm. One end of each support rod 9 slides into the sliding hole of the corresponding side support seat 8 with a sliding stroke of 300-400mm (adjustable nozzle spacing of 300-1000mm, suitable for apple trees with a row spacing of 1.5-3m). The other end is fixedly connected to the mounting seat of the nozzle 10 by an M5 bolt.

[0033] The nozzle 10 has two fan-shaped atomizing nozzles (model TTJ60-80), with a spray angle of 60-80° and atomized particle diameter of 50-100μm, ensuring that the fertilizer evenly covers the soil surface (coverage radius of 300-500mm); the water inlet of the nozzle 10 is equipped with a Φ15mm quick connector for easy disassembly and cleaning (to prevent fertilizer from clogging the nozzle).

[0034] Each nozzle 10 is connected to the storage tank 2 via a Φ12mm PVC telescopic hose 11. The telescopic hose 11 is 1000-1200mm long (to accommodate the maximum sliding stroke of the support rod and prevent breakage due to pulling). One end of the telescopic hose 11 is connected to the nozzle inlet via a quick connector, and the other end is connected to the Φ12mm outlet on the bottom side of the storage tank 2 via a quick connector (the outlet has a built-in filter to prevent impurities from entering the hose). A water pump 12 (miniature centrifugal pump, model 12V / 50W) is connected in series on both telescopic hoses 11. The water pump 12 is fixed to the upper part of the hand-pushed flatbed trolley 1 near the storage tank 2 with M4 bolts. The water pump 12 has its inlet connected to the hose on the storage tank 2 side and its outlet connected to the hose on the nozzle side, providing power for fertilizer transportation (head 3-5m, flow rate 8-10L / min).

[0035] The second drive mechanism achieves synchronous reverse sliding of the two side support rods 9 through the meshing of gear 15 and rack, adjusting the nozzle spacing to adapt to different apple tree row spacings. It includes a rotating shaft 13, gear 15, L-shaped rod 14 and limiting block 16.

[0036] The rotating shaft 13 is a Φ20mm No. 45 steel round shaft, 400-500mm in length, with a Φ16mm gear mounting journal machined in the middle of the shaft. The lower end of the rotating shaft 13 is mounted on a bracket welded to the upper part of the handcart 1 via a deep groove ball bearing (model 6203) (the bracket is 200-300mm from the handlebars). The upper end passes through the center hole of the U-shaped bracket 18 on the handlebars 21. A Φ30mm round handle is welded to the top of the shaft (for easy rotation by the operator). An M8 set screw 19 is also provided at the opening of the U-shaped bracket 18. A rubber pad is attached to the end of the set screw 19 to prevent scratching the outer wall of the rotating shaft 13 when tightening, thus locking the position of the rotating shaft 13.

[0037] Gear 15 is a spur gear with a module of 2 and 24 teeth (made of 45 steel with heat treatment). It is fixed to the gear mounting journal of the rotating shaft 13 by a flat key. The end face of the gear is in contact with the inner ring of the bearing. The gear is limited by a shaft retaining ring to ensure that the gear rotates synchronously with the rotating shaft and there is no axial movement.

[0038] There are two L-shaped rods 14, which are made of Φ16mm stainless steel rods bent (horizontal section length 300-400mm, vertical section length 100-150mm). The horizontal sections of the two L-shaped rods 14 are arranged opposite each other (on the side closer to the gear 15), and the outer wall of the horizontal section is machined with straight teeth that mesh with the gear 15 (module 2, number of teeth 18, tooth length matching the length of the horizontal section), forming a rack structure. The vertical section end of the L-shaped rod 14 is fixedly connected to the end of the support rod 9 on the same side near the support seat 8 by M5 bolts (bolt hole distance from the end of the support rod 50-80mm).

[0039] There are two limit blocks 16, which are rectangular metal blocks (60×40×25mm) and are fixed to the upper part of the hand-pushed flatbed trolley 1 with M6 bolts (located on both sides of gear 15, 100-150mm from the center of gear). The center of the limit block 16 has a sliding hole that matches the L-shaped rod 14. The horizontal section of the L-shaped rod 14 slides into the sliding hole. The inner wall of the sliding hole is covered with a rubber wear-resistant sleeve to ensure that the L-shaped rod can only slide horizontally (limiting vertical displacement) and avoid meshing misalignment.

[0040] When the handle of the rotating shaft 13 is turned, the gear 15 rotates, and through the meshing of the teeth of the L-shaped rods 14 on both sides, it drives the support rods 9 on both sides to extend outward synchronously, increasing the distance between the nozzles 10; when rotated in the opposite direction, the distance between the nozzles 10 decreases; after adjusting to the target distance, tighten the set screw 19 on the U-shaped bracket 18, and the end of the set screw presses against the outer wall of the rotating shaft 13, fixing the position of the rotating shaft through friction to prevent the nozzle distance from shifting during fertilization.

[0041] The auxiliary power supply component is battery 22. Battery 22 provides independent power to water pump 12, eliminating the need for an external power source and improving the portability of the equipment. It uses a 12V / 20Ah lead-acid battery (or a 12V / 15Ah lithium battery, which is lighter), measuring 180×77×167mm. It is mounted on the top of the handcart 1 using a plastic mounting bracket (with elastic clips). The bottom of the bracket is padded with rubber shock-absorbing pads to reduce the impact of pushing vibrations on the battery. The positive terminal of battery 22 is connected to a boat-shaped power switch (installed inside the rubber sleeve of handlebar 21 for easy one-handed operation) via a wire. The other end of the switch is connected to the positive terminals of the two water pumps 12 via two separate wires. The negative terminals of the two water pumps are connected to the negative terminal of the battery via a single wire, forming a circuit for single-switch control of simultaneous start and stop of the two water pumps. The wires are RVV2×1.0mm. 2 The copper core wire is covered with a PVC protective tube (to prevent orchard branches from scratching the wire).

[0042] The specific working process of this device is as follows: 1. Open the valve of the feed pipe 17 of the storage tank 2 and add fertilizer into the tank (if solid compound fertilizer is required, it needs to be dissolved in water at a ratio of 1:50 in advance and stirred into a uniform liquid fertilizer solution). After adding, close the valve. Check the power of the battery 22 (through the battery power indicator light) to ensure that the power is sufficient. Loosen the set screw 19 of the U-shaped bracket 18, turn the handle of the rotating shaft 13, and adjust the nozzle spacing 10 to match the row spacing of the apple trees (e.g., if the row spacing is 2m, adjust the nozzle spacing to 2m). Tighten the set screw 19 to fix it.

[0043] 2. The operator holds the handle 21 and pushes the hand-pushed flatbed cart 1 along the rows of apple orchards. During the push, the axle 20 drives the first drive mechanism, and the mixer 3 rotates synchronously to continuously stir the fertilizer in the tank to prevent stratification. When the cart reaches the apple tree to be fertilized, the operator presses the power switch on the handle 21, and the dual water pumps 12 start up. The fertilizer in the tank is pressurized and then transported to the nozzle 10 through the telescopic hose 11. After atomization, the fertilizer is sprayed onto the soil around the roots of the apple tree. The operator moves the cart to the next apple tree and repeats the spraying action until the fertilization of the row is completed.

[0044] 3. After fertilizing an area, turn off the power switch and stop the water pump. If you need to continue working, push the equipment to the refueling point and open the feed pipe to replenish fertilizer. If you have finished working, push the equipment to the storage point, open the drain valve at the bottom of the storage tank (not shown in the figure), empty the residual fertilizer in the tank, and rinse the storage tank 2, telescopic hose 11 and nozzle 10 with clean water to prevent fertilizer residue from clogging the pipeline. Disconnect the battery switch 22. If the battery will not be used for a long time, it needs to be removed, charged and stored.
