Description

Technical Field

[0001] This utility model relates to the field of soil turning technology, and in particular to a manual soil turning device for small-area strawberry planting. Background Technology

[0002] In small-scale strawberry cultivation scenarios (such as family vegetable gardens and small strawberry fields), loosening the topsoil and controlling the depth of tilling are crucial for strawberry growth. Strawberry roots are shallowly distributed, and tilling too deeply can easily damage the roots, affecting nutrient absorption and plant survival rate. Tilling too shallowly cannot effectively break up the compacted topsoil, making it difficult to meet the needs of root respiration and soil improvement. At the same time, small plots have limited space, and large agricultural tilling equipment is not suitable due to its large size and poor maneuverability. In actual operation, traditional manual tools or simple small tilling devices are mostly relied upon.

[0003] In the existing technology, the soil turning tools commonly used in small-scale strawberry planting have obvious defects: First, traditional manual hoes, rakes and other tools rely entirely on the operator's experience to control the soil turning depth. When facing soils with different hardness (such as locally compacted soil and loose soil), it is difficult to adjust the depth accurately. In areas of compacted soil, it is easy to turn the soil too deep due to increased downward pressure, while in areas of loose soil, it is easy to turn the soil too shallow due to improper control of force. Not only is the work efficiency low, but it is also easy to cause uneven soil turning depth within the plot. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a manual soil-turning device for small-area strawberry cultivation.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a manual soil turning device for small-area strawberry cultivation, comprising a main support frame extending horizontally, a repair agent storage tank fixedly mounted at the top of one end of the main support frame along its length, a storage tank sealing cap covering the top opening of the repair agent storage tank, a repair agent delivery pump connected to the bottom of the repair agent storage tank, a pesticide spraying pipe fixedly connected to the output end of the repair agent delivery pump, the pesticide spraying pipe being horizontally arranged along the width of the main support frame, and its two ends being fixedly connected to the inner walls of both sides of the main support frame, a lifting adjustment component vertically fixed to the outer wall of the main support frame away from the repair agent storage tank, the output end of the lifting adjustment component extending downwards vertically and fixedly connected to a loosening roller mounting frame, the loosening roller mounting frame being U-shaped. The structure has soil loosening rollers connected horizontally through its inner walls on both sides. A soil loosening drive motor is fixedly connected to one end of the soil loosening roller. The outer side of the housing of the soil loosening drive motor is fixedly connected to one outer wall of the soil loosening roller mounting frame. Sliding direction positioning rods are vertically fixed at both ends of the top of the soil loosening roller mounting frame. The sliding direction positioning rods pass vertically upward through the main support frame and slide in cooperation with the main support frame. The soil loosening roller mounting frame slides along the vertical direction of the main support frame with the help of the sliding direction positioning rods, so as to limit the height adjustment of the soil loosening roller mounting frame to only the vertical direction. The output end of the soil loosening drive motor drives the soil loosening roller to rotate.

[0006] Preferably, the inner wall of the storage hopper sealing cover is equipped with a stirring device, and an auxiliary device is provided on the side of the main support frame near the soil loosening roller. The stirring device includes a stirring drive motor, which is vertically fixed at the top center of the storage hopper sealing cover. Its output end is vertically inserted through the storage hopper sealing cover and fixedly connected to a stirring transmission rod. The stirring transmission rod extends vertically into the interior of the repair agent storage hopper, and its bottom end is horizontally fixedly connected to a repair agent stirring arm. The stirring transmission rod and the repair agent stirring arm are inserted into the inner wall of the repair agent storage hopper. After the stirring drive motor is started, it drives the stirring transmission rod to rotate around its own axis, thereby driving the repair agent stirring arm to rotate synchronously inside the repair agent storage hopper.

[0007] Preferably, a component connecting seat is horizontally fixedly connected to the bottom end of the repair agent stirring arm. A sinking agent roller is rotatably connected to the side of the component connecting seat near the bottom of the repair agent storage tank in the horizontal direction. The outer wall of the sinking agent roller is in contact with the inner wall of the bottom of the repair agent storage tank. When the repair agent stirring arm rotates, it drives the component connecting seat to move synchronously in a circular motion. During the movement of the component connecting seat, the sinking agent roller contacts the bottom of the repair agent storage tank and rotates around its own axis.

[0008] Preferably, a bucket bottom scraper is fixedly connected to the side of the component connecting seat away from the bottom-sinking agent roller along the length direction of the component connecting seat. The bottom edge of the bucket bottom scraper is tightly fitted to the bottom inner wall of the repair agent storage tank. When the component connecting seat rotates, it drives the bucket bottom scraper to move synchronously to scrape off the repair agent adhering to the bottom of the repair agent storage tank.

[0009] Preferably, a stirring structure reinforcing rod is symmetrically fixedly connected to the outer surface of the stirring transmission rod along its circumference. The stirring structure reinforcing rod extends horizontally along the radial direction of the stirring transmission rod, and its end away from the stirring transmission rod is fixedly connected to the inner sidewall of the repair agent stirring arm to enhance the structural stability of the connection between the stirring transmission rod and the repair agent stirring arm.

[0010] Preferably, a motor protective cover is fixedly connected to the outer wall of the soil loosening roller mounting frame near the soil loosening drive motor. The motor protective cover has a U-shaped cover structure and is fitted onto the outer surface of the soil loosening drive motor to prevent external objects from colliding with the soil loosening drive motor.

[0011] Preferably, roller shaft rotating bearings are fixedly connected to both ends of the soil loosening roller. The inner ring of the roller shaft rotating bearing is fixed to the end of the soil loosening roller, and the outer ring is fixed to the inner walls of both sides of the loosening roller mounting frame. When the loosening drive motor drives the soil loosening roller to rotate around its own axis, the roller shaft rotating bearings reduce the rotational wear between the soil loosening roller and the loosening roller mounting frame.

[0012] Preferably, a nozzle anti-clogging baffle is vertically fixed between the inner walls of the main support frame. The nozzle anti-clogging baffle is located on the side of the pesticide spraying pipe facing the soil loosening roller to prevent soil particles carried up by the soil loosening roller from falling onto the pesticide spraying pipe and causing blockage.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the lifting and adjusting assembly (manual hydraulic telescopic rod or threaded lifting component) supports manual adjustment of the loosening roller height. Operators can flexibly control the turning depth according to soil hardness (compacted soil, loose soil), ensuring that the loosening teeth only break the surface soil (adapting to the shallow root distribution characteristics of strawberries) and avoiding damage to the strawberry roots from excessive turning. At the same time, the double-rod guide structure formed by the sliding direction positioning rod can prevent the loosening roller mounting frame from shifting or tilting during lifting.

[0016] Example 1, as Figure 1-4 As shown, a manual soil-turning device for small-area strawberry cultivation includes a main support frame 1 as the basic support carrier. The entire device features a lightweight, manually operated design, specifically tailored for small strawberry cultivation plots (such as family vegetable gardens or small strawberry fields), avoiding the lack of flexibility of large equipment in small areas. The main support frame 1 is constructed from metal profiles of suitable strength, welded together, with the overall weight controlled within a range that can be pushed by a single person, ensuring convenient manual operation. Universal casters with brakes are installed near the four corners of the frame's bottom, facilitating flexible steering during operation and providing a secure hold during stationary operation to prevent the device from shifting on its own.

[0017] The repair agent storage tank 16 has a cylindrical structure with a capacity suitable for single small-area operations (it can store enough repair agent and water for a single plot of work at once). An opening is provided at the top of the tank, sized for easy manual addition of solid repair agent and water. An outlet is located at the center of the bottom of the tank, with a threaded sealing connector welded to the outlet for connection to the inlet pipe of the repair agent delivery pump 18. A sealing gasket can be installed at the connector to prevent leakage. The storage tank sealing cap 17 is a circular cap matching the size of the opening at the top of the repair agent storage tank 16. A silicone sealing ring is embedded in the inner edge of the cap, ensuring a tight seal when closed, preventing splashing of repair agent or leakage of odors during mixing. A perforation is provided at the center of the top of the sealing cap for the transmission rod 3 to pass through. A rubber sealing sleeve is installed inside the perforation, ensuring smooth rotation of the transmission rod while preventing repair agent leakage from the perforation gaps. The repair agent delivery pump 18 is a miniature DC centrifugal pump with flow and pressure adapted to the needs of uniform spraying in small areas (ensuring stable liquid output from the nozzle without significant flow interruption or excessive spraying). Its inlet pipe is fixedly connected to the bottom outlet of the repair agent storage tank 16 through a threaded joint, and the other end of the outlet pipe is fixed to the inlet of the agent spraying pipe 19 by welding or clamping. The pump body is fixed to the outer wall of the main support frame 1 near the repair agent storage tank 16 by an L-shaped metal bracket. The installation height avoids water stains on the ground and facilitates manual operation of the switch and daily maintenance.

[0018] The pesticide spraying pipe 19 ensures that the spraying range can completely cover the subsequent soil loosening area to avoid missed spraying. Spraying holes are evenly opened along the length of the pipe body. Each spraying hole is equipped with an adjustable fan-shaped nozzle. The spraying angle of the nozzle can be adjusted according to the row spacing of strawberry planting to ensure that the repair agent is evenly covered on the soil surface along the width of the frame. The spraying pipe is fixed to the inner walls of both sides of the main load-bearing frame 1 by U-shaped clamps. The installation height must avoid ground protrusions to prevent the nozzle from directly contacting the soil and causing blockage. The pipe body is perpendicular to the length of the frame to ensure that the spraying path corresponds precisely to the soil loosening path, so as to achieve the effect of simultaneous operation of spraying pesticides immediately after turning the soil.

[0019] The lifting adjustment component 9 can be equipped with a manual hydraulic telescopic rod or a threaded lifting component (i.e., a threaded rod that is rotatably connected to the loosening roller, and the threaded rod is rotatably connected to the main bearing frame 1). The cylinder is fixed to the outer wall of the main bearing frame 1 at the end away from the repair agent storage tank 16 by bolts. The installation height is flush with the top of the frame, which is convenient for manual bending operation. The output end of the telescopic rod extends downward in the vertical direction, and the end is fixedly connected to the top center of the loosening roller mounting frame 10 through a flange. A rubber gasket is added to the flange to enhance the connection sealing and stability. The telescopic component is equipped with a manual pressure rod (used to drive the telescopic rod to extend and drive the loosening roller to descend) and a pressure relief valve (used to control the telescopic rod to retract and drive the loosening roller to rise). The operation logic is simple and can be quickly mastered by personnel in the relevant technical field. It is convenient to adjust the turning depth according to the soil hardness (such as compacted soil or loose soil) to ensure that it is suitable for the shallow root growth needs of strawberries (avoiding damage to the root system by turning the soil too deeply).

[0020] The soil loosening roller mounting frame 10 has an opening facing downwards. The height of the frame is adapted to the length of the soil loosening roller 11. The thickness of the side wall meets the bearing requirements of the soil reaction force during the loosening process to prevent deformation. A bolt hole is opened at the center of the top of the frame, which is fixed to the flange at the output end of the lifting adjustment component 9 by bolts to ensure a firm connection. Symmetrical through holes are opened at both ends of the top of the frame for inserting the sliding direction positioning rod 20. The inner wall of the through hole is polished smooth to reduce the frictional resistance when the positioning rod slides.

[0021] The soil loosening roller 11 has a cylindrical structure with multiple sets of spiral loosening teeth evenly welded along the axial direction on its surface. The loosening teeth are made of wear-resistant manganese steel to avoid wear caused by long-term soil turning. The height and spacing of the loosening teeth are adapted to the soil loosening requirements of strawberry planting, which can effectively break up the surface compacted soil without excessively damaging the soil aggregate structure, thus ensuring the growth environment of strawberry roots. Both ends of the roller are machined with journals, and the journal size is adapted to the inner ring of the roller shaft rotating bearing 14 to ensure smooth rotation of the roller. The output speed of the soil loosening drive motor 12 is adapted to the soil loosening requirements (too high a speed will easily cause soil splashing, and too low a speed will not be able to break up compacted soil). The motor housing is fixed to the outer wall of one side of the soil loosening roller mounting frame 10 by multiple sets of bolts. The installation position is close to the end of the roller to reduce power transmission loss. The motor output shaft is fixedly connected to one end journal of the soil loosening roller 11 through a coupling. An elastic washer is installed at the coupling to buffer the impact force when the motor starts, ensuring stable power transmission and driving the roller to rotate at a constant speed around its own axis.

[0022] The sliding direction positioning rod 20 consists of two steel round rods, which are welded or bolted to the through holes at both ends of the top of the loosening roller mounting frame 10. The rods are vertically inserted through the guide holes at the corresponding positions of the main bearing frame 1. The guide holes and the rods are fitted with a clearance (to ensure smooth sliding while limiting lateral displacement). The two positioning rods are symmetrically arranged to form a double-rod guide structure, which can effectively prevent the loosening roller mounting frame 10 from shifting left or right or tilting during the lifting and lowering process, ensuring that the loosening depth of the soil loosening roller 11 is uniform and consistent, and avoiding local over-tillage or under-tillage.

[0023] The housing of the stirring drive motor 2 is fixed to the top center of the storage tank sealing cover 17 by multiple sets of bolts, and is coaxially set with the through hole of the sealing cover to ensure precise docking of the motor output shaft and the stirring transmission rod 3. The motor output shaft passes vertically downward through the sealing cover and is fixed to the stirring transmission rod 3 by a key connection. A positioning pin is added to the key connection to prevent slippage during transmission and ensure stable power transmission.

[0024] The stirring rod 3 is made of stainless steel round rod, and its length is adapted to the height of the repair agent storage tank 16, ensuring that the bottom of the rod can extend into the lower area of ​​the storage tank (covering the location of the settled repair agent). The surface of the rod is polished smooth to reduce repair agent residue and facilitate subsequent cleaning. The top of the rod is fixed to the output shaft of the stirring drive motor 2, and two repair agent stirring arms 4 are symmetrically welded radially at the bottom. The welding joint uses a full welding process to enhance the connection strength and prevent the stirring arms from falling off due to centrifugal force during stirring. The repair agent stirring arms 4 are two stainless steel flat rods. The stirring rod 3 is vertical, and the length of the stirring arms is less than the inner diameter of the repair agent storage tank 16 to avoid collision with the tank wall during stirring, which may cause noise or damage to parts. The stirring arms rotate synchronously with the stirring rod 3 around the vertical axis, forming a circumferential stirring trajectory that can cover most of the area inside the storage tank, ensuring that the repair agent and water are initially mixed evenly.

[0025] The component connecting seat 5 is a rectangular stainless steel block, which is welded to the bottom end of the repair agent mixing arm 4. The welding position is located on the side of the mixing arm away from the barrel wall to avoid collision with the barrel wall during movement. A shaft hole is opened on one side of the component connecting seat 5 for installing the settling agent grinding roller 6, and the bottom agent scraper 7 is fixed to the other side with bolts to achieve synchronous movement of the grinding roller and the scraper, thereby improving mixing efficiency. The settling agent grinding roller 6 is a cylindrical roller made of rubber (the rubber material avoids damage to the bottom of the storage barrel). A stainless steel shaft core is inserted through the center of the roller body. The two ends of the shaft core are rotated and engaged with the shaft hole of the component connecting seat 5 through small bearings. During the mixing process, the outer wall of the grinding roller is in contact with the inner wall of the bottom of the repair agent storage barrel 16. When the mixing arm moves in a circle, the grinding roller rotates around its own axis due to friction with the bottom of the barrel, which can crush the large particles of repair agent that have settled to the bottom, accelerate their dissolution and mixing, and solve the problem of uneven mixing caused by the settling of solid repair agent. The bottom scraper 7 is made of elastic plastic, possessing a certain degree of flexibility. It can fit tightly against the bottom of the storage tank without damaging the tank wall. The top of the scraper is fixed to the component connecting seat 5 with bolts, and the bottom edge has a very small gap with the inner wall of the storage tank bottom (ensuring that residual repair agent can be scraped off). During the stirring process, the scraper moves synchronously with the component connecting seat 5, which can scrape off the repair agent adhering to the bottom of the tank, avoiding residue and waste. At the same time, it further disperses the settled material and improves the overall mixing uniformity. The stirring structure reinforcement rod 8 consists of two stainless steel diagonal rods, which are welded to the lower part of the stirring transmission rod 3 and the inner side wall of the two repair agent stirring arms 4, forming a triangular support structure. The triangular support design can significantly enhance the connection strength between the stirring transmission rod 3 and the stirring arms, preventing the stirring arms from deforming or breaking due to centrifugal force during stirring, ensuring the long-term stable operation of the stirring device and adapting to the needs of repeated operations.

[0026] The motor protective cover 13 has a U-shaped structure. The cover is strong enough to withstand minor collisions and soil impacts. Multiple circular heat dissipation holes are opened on the side wall of the cover to ensure that the heat of the soil loosening drive motor 12 can be dissipated in time during operation, avoiding overheating damage to the motor. The cover is fixed to the outer wall of the soil loosening roller mounting frame 10 near the soil loosening drive motor 12 by bolts. It is fitted onto the outer surface of the soil loosening drive motor 12, with an appropriate heat dissipation gap between it and the motor housing. Its core function is to prevent soil, weeds and debris splashed during soil turning from entering the motor (preventing short circuits or jamming of the motor), while also preventing the motor housing from directly colliding with hard objects, thus extending the service life of the motor. The nozzle anti-clogging baffle 15 is made of transparent PC plastic sheet, which has impact resistance and aging resistance. The transparent design makes it easy to observe the spraying status of the nozzle during operation. The baffle is fixed at an angle between the inner walls of the main support frame 1 by a metal bracket and is located on the side of the pesticide spraying pipe 19 facing the soil loosening roller 11 (maintaining an appropriate distance from the spraying pipe so as not to block the spraying range of the nozzle). The baffle is tilted at a certain angle to the vertical direction (towards the soil loosening roller 11). This tilt angle can effectively guide the soil and weed debris brought up during loosening to fall downwards, preventing them from falling at the nozzle of the pesticide spraying pipe 19 and causing blockage, ensuring continuous and smooth pesticide spraying and reducing operation interruption time.

[0027] Working principle Open the sealed cap 17 of the storage tank, add strawberry-specific solid remediation agent (such as soil conditioner or microbial agent) and water to the remediation agent storage tank 16, and control the solid-liquid ratio according to the product instructions of the remediation agent (ensure that the concentration of the remediation agent meets the soil remediation requirements and avoid excessively high or low concentrations that may affect the effect). After adding, observe the liquid level in the storage tank and avoid exceeding 80% of the tank's volume (to prevent overflow during stirring).

[0028] Cover the storage tank with the sealing cap 17, ensuring the sealing ring fits tightly without any obvious gaps. Turn off the power switches of the repair agent delivery pump 18 and the loosening drive motor 12 (if battery powered, check the battery level; if external power is used, check the wiring connection). Adjust the height of the loosening roller using the manual lever and pressure relief valve of the lifting adjustment component 9, so that the loosening teeth of the soil loosening roller 11 gently touch the ground. Initially set the turning depth (suitable for strawberry shallow root systems, usually not exceeding the depth of strawberry root distribution). Start the stirring drive motor 2. The motor drives the stirring transmission rod 3 to rotate around the vertical axis, which in turn drives the repair agent stirring arm 4 to make a circular motion. Observe the stirring status. During the stirring process, the bottom-sediment grinding roller 6 rotates against the bottom of the tank, crushing large particles of repair agent. The bottom-sediment scraper 7 scrapes away the residue at the bottom of the tank until the repair agent and water are evenly mixed (no obvious particle sedimentation, and the liquid is in a homogeneous state). After stirring is completed, the motor can be kept running at a low speed (to prevent static sedimentation), or the motor can be started and stopped according to the work rhythm. A single person pushes the main support frame 1, moving it at a uniform speed along the strawberry planting row (the speed is adapted to the synchronization of loosening and spraying to avoid missing loosening or spraying due to excessive speed, and reducing work efficiency due to excessive slowness). At the same time, the loosening drive motor 12 and the repair agent delivery pump 18 are started: the loosening drive motor 12 drives the soil loosening roller 11 to rotate, the loosening teeth break the surface soil to form a loose soil layer, and the repair agent delivery pump 18 draws the evenly mixed repair agent from the storage tank and sprays it evenly on the loosened soil surface through the nozzle of the agent spraying pipe 19. During the operation, the status of the nozzle is observed through the anti-clogging baffle 15 of the spray pipe. If a slight blockage is found in the nozzle, the operation can be stopped to clean it to ensure even spraying.

[0029] When encountering hard, compacted soil during operation, lower the loosening roller height appropriately using the manual lever of the lifting adjustment component 9 to increase the turning depth and ensure sufficient soil breaking. When encountering soft soil, open the pressure relief valve to raise the loosening roller and reduce the turning depth to avoid excessive damage to the soil structure. If uneven spraying of the repair agent is found, adjust the nozzle angle or check the flow rate of the delivery pump to ensure the spraying effect. After completing the operation of a single plot, turn off the mixing drive motor 2, the loosening drive motor 12, and the repair agent delivery pump 18. Open the sealing cover 17 of the storage tank, add clean water to the repair agent storage tank 16, start the mixing device and the repair agent delivery pump 18, and rinse the inner wall of the storage tank, the delivery pipe, and the nozzle (to prevent the repair agent residue from solidifying and clogging). After rinsing, drain the wastewater, move the device to a dry and ventilated place for storage, clean the soil and weeds on the surface of the device, regularly check the wear of the loosening teeth and the aging of the seals, replenish grease to the bearings and other parts, and replace damaged wear parts (such as nozzles and sealing rings) to ensure the device operates normally for the next operation.
