Description

Technical Field

[0001] This utility model relates to the field of agricultural seedling technology, and in particular to an agricultural seedling water spraying device. Background Technology

[0002] In the field of agricultural seedling cultivation, seedlings have high requirements for the uniformity of water supply, the adaptability of irrigation height, and the protection of equipment when not in operation. Existing seedling spraying equipment still has many shortcomings in practical applications, specifically as follows: Traditional seedling spraying devices are mostly designed with a fixed height, or can only be adjusted by manually raising the base, making it difficult to flexibly adapt to seedling racks of different heights (such as dwarf seedling trays and multi-layer vertical seedling racks). For seedlings at higher positions, problems such as insufficient spray range and inability to cover the atomization area are likely to occur; if the entire equipment is forcibly raised, it will lead to a decrease in equipment stability, increase the risk of tipping over, and make it difficult to meet the irrigation needs of diverse seedling cultivation scenarios.

[0003] In summary, there is an urgent need for a new type of seedling irrigation device that can solve the above problems in order to improve the accuracy and efficiency of seedling irrigation. Utility Model Content

[0004] To address the problems in the background art, this application provides an alternative solution: an agricultural seedling spraying device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an agricultural seedling watering device, comprising a supporting base, an atomizing water sprayer, a stop device, and an anti-clogging component. The supporting base is horizontally arranged, and several casters are uniformly fixedly connected to its bottom along the circumference. The casters protrude from the bottom surface of the supporting base to enable horizontal movement of the entire device. A main support frame is vertically fixed to one side of the top of the supporting base. The atomizing water sprayer is rotatably connected to the main support frame via a horizontally arranged rotating shaft. The axis of the rotating shaft is perpendicular to the vertical surface of the main support frame, and the end of the rotating shaft passing through the main support frame away from the atomizing water sprayer is coaxially fixed with a component. The disc and the main support frame are provided with several sets of angle positioning holes along the circumference. Each set of angle positioning holes can be locked by inserting a fixing pin to lock the angle of the rotating shaft, thereby controlling the pitch angle of the atomizing water sprayer around the rotating shaft. A water storage container is placed on the other side of the top of the support base. A water supply pump is fixedly installed inside the water storage container. The water outlet of the water supply pump is connected to the water inlet of the atomizing water sprayer through a flexible delivery pipe to provide a high-pressure water source for the atomizing water sprayer. An operation control panel is fixedly installed on the top of the support base near the main support frame. A push handle is fixedly installed on the side wall of the support base away from the main support frame along the horizontal direction.

[0006] Preferably, the stopping device is assembled at the bottom of the bearing base and includes a lifting hydraulic rod and a supporting base plate. The bottom of the bearing base has a recessed storage groove corresponding to the position of the stopping device. The top of the inner wall of the storage groove is perpendicularly fixed to the fixed end of the lifting hydraulic rod. The output end of the lifting hydraulic rod extends downward in the vertical direction and is perpendicularly fixed to the center of the upper surface of the supporting base plate. The lifting hydraulic rod can drive the supporting base plate to reciprocate in the vertical direction, so that the supporting base plate protrudes from the bottom surface of the movable universal wheel or is stored in the storage groove.

[0007] Preferably, two guide limiting posts are symmetrically and vertically fixed on the upper surface of the support base plate along its length direction. Fixed square plates are vertically fixed on both sides of the bearing base corresponding to the positions of the guide limiting posts. The fixed square plates are provided with sliding through holes coaxial with the guide limiting posts. The outer wall of the guide limiting post slides in cooperation with the inner wall of the sliding through hole. When the lifting hydraulic rod drives the support base plate to move vertically, the guide limiting post slides vertically synchronously along the inner wall of the sliding through hole, thus limiting the horizontal sway of the support base plate.

[0008] Preferably, the outer wall of the output end of the lifting hydraulic rod is uniformly and fixedly connected with a number of reinforcing support ribs along the circumferential direction. The end of each reinforcing support rib away from the lifting hydraulic rod is fixedly connected to the upper surface of the support base plate, and the reinforcing support ribs are arranged at an incline to form a triangular support for the connection node between the output end of the lifting hydraulic rod and the support base plate.

[0009] Preferably, a plurality of anti-slip rubber strips are fixedly connected to the lower surface of the supporting base plate along its length direction. The plurality of anti-slip rubber strips are arranged in parallel at equal intervals along the width direction of the supporting base plate, and the anti-slip rubber strips protrude from the lower surface of the supporting base plate to increase the friction between the supporting base plate and the ground.

[0010] Preferably, the anti-clogging component is assembled at the outlet end of the atomizing water sprayer and includes a secondary support frame, an anti-clogging cover, and a fixing buckle. The secondary support frame is L-shaped, with one end fixedly connected to the outer wall of the atomizing water sprayer outlet. The other end of the secondary support frame is rotatably connected to one side edge of the anti-clogging cover via a vertically arranged hinge shaft. The anti-clogging cover can rotate horizontally around the hinge shaft, allowing it to close to or offset from the outlet end of the atomizing water sprayer. The outer contour dimensions of the anti-clogging cover are... The size of the cover is larger than the inner contour of the outlet end of the atomizing water sprayer to ensure that the anti-clogging cover can completely cover the outlet end of the atomizing water sprayer. The outer wall of the outlet end of the atomizing water sprayer has a flared interface corresponding to the position of the anti-clogging cover. When the anti-clogging cover is closed, its inner wall fits and aligns with the inner wall of the flared interface. The anti-clogging cover and the flared interface both have corresponding slots. The outer wall size of the fixing buckle is adapted to the inner wall size of the slot. The fixing buckle can be inserted into the slot to achieve a fixed lock between the anti-clogging cover and the atomizing water sprayer.

[0011] Preferably, the outer wall of the fixing buckle is fixedly connected with a plurality of anti-slip protrusions along its length. The anti-slip protrusions protrude from the outer wall of the fixing buckle. The inner wall of the anti-clogging cover and the flared interface is provided with a matching groove corresponding to the position of the anti-slip protrusion. When the fixing buckle is inserted into the groove, the anti-slip protrusion engages with the groove, increasing the friction between the fixing buckle and the groove.

[0012] Preferably, a flexible connecting rope is fixedly connected to the outer wall of one end of the fixing buckle, and the end of the connecting rope away from the fixing buckle is fixedly connected to the outer wall of the anti-clogging cover. When the fixing buckle is pulled out of the slot, the connecting rope can restrict the relative separation between the fixing buckle and the anti-clogging cover, thus preventing the fixing buckle from being lost.

[0013] Preferably, a handle is fixedly connected to the outer wall of the anti-clogging cover on the side away from the hinge axis. The cross-section of the handle is U-shaped, and the opening direction of the handle is away from the anti-clogging cover, so as to facilitate the operator to hold and drive the anti-clogging cover to rotate around the hinge axis.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the lifting hydraulic rod in the stop device works in conjunction with the supporting base plate to drive the bearing base and the atomizing water sprayer to move flexibly up and down in the vertical direction. When irrigating higher seedling racks, the lifting hydraulic rod is activated to make the supporting base plate touch the ground and raise the base, driving the atomizing water sprayer to rise to the target height. When irrigating low-growing seedlings, the hydraulic rod is retracted to lower the base, ensuring that the atomizing water sprayer maintains a reasonable distance from the seedlings. At the same time, the atomizing water sprayer is rotatably connected to the main support frame through a rotating shaft. With the help of angle positioning holes and fixing pins, the pitch angle can be locked, achieving dual adjustment of height and angle. This ensures that the atomized water flow evenly covers seedlings of different heights and placement angles, avoiding irrigation blind spots or local water accumulation, and improving the accuracy of seedling irrigation.

[0015] In this invention, the anti-clogging component at the outlet of the atomizing water sprayer provides all-around protection when the equipment is not in operation. The anti-clogging cover is rotatably connected to the hinge shaft via a secondary support frame, completely blocking the nozzle when covering the outlet. The locking buckle and the slot of the flared interface cooperate with the locking action of the anti-slip protrusion to ensure that the cover fits firmly and prevents debris from entering. The connecting rope prevents the buckle from being lost and reduces wear and tear on accessories. This structure can complete the protective operation without disassembly, effectively blocking dust, seedling substrate and other debris from entering the nozzle, greatly reducing the probability of nozzle clogging, reducing the number of equipment maintenance and cleaning time, reducing the maintenance cost of seedling irrigation and extending the service life of the equipment.

[0018] Example 1, such as Figure 1-3 As shown, the agricultural seedling spraying device uses the support base 1 as the core load-bearing component. The overall structure is arranged horizontally in a cuboid shape and is welded from high-strength steel plates to ensure that the structural strength is sufficient to support the weight of each component. Several omnidirectional casters 10 are evenly fixedly connected to the bottom of the support base 1 along the circumference. The omnidirectional casters 10 protrude from the bottom surface of the support base 1 and are used to realize the horizontal movement of the entire device. The casters are equipped with brake pads for temporary positioning. On the side wall (the side along the length direction) of the support base 1 away from the main support frame 11, a push handle 23 is welded and fixed horizontally. The handle is made of galvanized steel pipe bent into a "U" shape to fit the hand grip position when the operator is standing and pushing.

[0019] Near the short side of the top of the support base 1, a main support frame 11 is vertically welded. This frame is composed of two symmetrically arranged "L"-shaped steel plates, the distance between which is adapted to the width of the atomizing water sprayer 12. The atomizing water sprayer 12 is a small high-pressure atomizing mist cannon. A rotating shaft 121 is symmetrically welded on both sides of its body. The axis of the rotating shaft 121 is perpendicular to the facade of the main support frame 11, and both ends are inserted into the reserved holes in the two steel plates of the main support frame 11, so as to realize the pitch rotation of the atomizing water sprayer 12 around the rotating shaft 121. The rotating shaft 121 passes through one end of the outer side of the main support frame 11, and a circular baffle is coaxially welded thereon. The baffle and the outer steel plate of the main support frame 11 have multiple sets of angle positioning holes 111 evenly opened along the circumference. By inserting the fixing pin 122 (spring pin), the atomizing water sprayer 12 can be locked at a suitable angle to adapt to the water spraying needs of seedling racks of different heights.

[0020] On the side of the top of the support base 1 away from the main support frame 11, a water storage container 20 is placed. It is preferably a water tank made of food-grade PE material. The water tank has a water inlet (with a dust cover) on the top and a drain valve at the bottom. A water supply pump 21 is fixedly installed at the center of the bottom surface of the water storage container 20 by bolts. The water outlet of the water supply pump 21 is connected to the water inlet of the atomizing water sprayer 12 through a steel wire hose. The hose length is reserved to accommodate the displacement of the atomizing water sprayer 12 during pitch and rotation. On the side of the top of the support base 1 close to the main support frame 11, an operation control panel 22 is fixed by bolts. The control panel integrates a power switch, a water supply pump start / stop button, a lifting hydraulic rod control knob, and an atomizing water sprayer angle adjustment indicator. The internal circuit is electrically connected to the water supply pump 21 and the lifting hydraulic rod 3 to achieve centralized control.

[0021] Stopping devices 2 are used for stable support during device operation to prevent the casters 10 from slipping. Multiple sets are provided (evenly distributed at the bottom of the support base). Each set includes a lifting hydraulic rod 3, a support base plate 4, guide and limiting posts 5, and reinforcing ribs 8. A storage groove 2 (rectangular recess) is provided at the bottom of the support base 1 corresponding to the position of each stopping device. The lifting hydraulic rod 3 is fixed to the top of the inner wall of the storage groove by bolts. The fixed end of the hydraulic rod faces upwards, and the output end extends downwards in the vertical direction. The end is welded to the center of the upper surface of the support base plate 4 via a flange. The support base plate 4... High-strength steel plate is used, and multiple anti-slip rubber strips 9 (made of nitrile rubber with a trapezoidal cross-section) are bonded to the lower surface along its length. By increasing the coefficient of friction with the ground, slippage is prevented during support. Two guide limiting posts 5 are symmetrically welded to the upper surface of the support base plate 4 along its length. A square plate 6 is vertically welded to both sides of the bearing base 1 at the positions of the guide limiting posts. A sliding through hole 7 is opened in the center of the square plate, and the guide limiting posts 5 are inserted into the sliding through hole with the gap controlled within a reasonable range. When the lifting hydraulic rod 3 drives the support base plate 4 to move vertically, the guide limiting posts 5 slide along the through hole. The inner wall of the moving perforation 7 slides synchronously, limiting the horizontal swaying of the support base plate and ensuring smooth lifting. Multiple reinforcing support ribs 8 (high-strength steel bars) are evenly welded to the outer wall of the output end of the lifting hydraulic rod 3 along the circumferential direction. One end of each rib is welded to the output end of the hydraulic rod, and the other end is welded to the upper surface of the support base plate 4. The ribs form a reasonable angle with the axis of the hydraulic rod, creating a triangular support structure. This disperses the axial force at the output end of the hydraulic rod to the support base plate, preventing deformation of the connection nodes due to concentrated force. When the device moves, the output end of the lifting hydraulic rod 3 retracts, and the support base plate... 4. The device is stored in the storage slot 2 (the bottom surface of the support base plate is flush with the bottom surface of the caster wheels). At this time, the device moves by means of the caster wheels. After the device reaches the working position, the lifting hydraulic rod is activated by the operation control panel 22. The output end extends and drives the support base plate 4 to move downward until the anti-slip rubber strip 9 is in close contact with the ground. It continues to extend to raise the bearing base 1 and the caster wheels 10 leave the ground. At this time, the device is stably supported by multiple sets of stop devices and completes the stop positioning. When it needs to move again, the hydraulic rod is retracted, the support base plate is stored, and the caster wheels can be placed on the ground.

[0022] The anti-clogging component 3 is used for outlet protection of the atomizing water sprayer 12 when it is not in operation, to prevent dust, seedling substrate and other debris from entering the nozzle and causing blockage. An "L"-shaped secondary support frame 13 (made of bent stainless steel round steel) is welded and fixed to the outer wall of the outlet end of the atomizing water sprayer 12 (at a reasonable location). The vertical end of the secondary support frame is rotatably connected to one edge of the anti-clogging cover 14 via a hinge shaft (made of brass). The anti-clogging cover 14 is made of transparent PC material, and its outer contour dimension is larger than the inner diameter of the outlet end of the atomizing water sprayer to ensure complete coverage of the outlet. A handle 19 (U-shaped structure) is integrally formed on the edge of the cover away from the hinge shaft for easy gripping and rotation by the operator. A flared interface 15 (trumpet-shaped) is welded to the outer wall of the outlet end of the atomizing water sprayer 12 (corresponding to the position where the anti-clogging cover is closed). The inner wall of the flared interface fits snugly against the inner wall of the anti-clogging cover 14 (with a reasonable gap). The anti-clogging cover 14 and the flared interface 15 are positioned at corresponding positions. Each component has a circular slot, into which a fixed buckle 16 (made of nylon, cylindrical) is inserted. Multiple hemispherical anti-slip protrusions 17 are evenly distributed along the length of the outer wall of the fixed buckle. Corresponding grooves are provided on the inner wall of the slot. When the buckle is inserted into the slot, the anti-slip protrusions engage with the grooves to prevent the buckle from loosening. One end of the fixed buckle 16 is bound to the outer wall of the anti-clogging cover 14 via a connecting rope 18 (nylon rope) to prevent loss after the buckle is pulled out. When the device is working, hold the handle 19 and rotate the anti-clogging cover 14 horizontally around the hinge axis (at a suitable angle) to make the cover deviate from the outlet of the atomizing water sprayer. Then pull out the fixed buckle 16 (the buckle is suspended on the cover via the connecting rope), and the atomizing water sprayer can be started. After operation, rotate the cover in the opposite direction to cover the outlet, aligning the cover slot with the flared interface slot, and insert the fixed buckle 16 until the anti-slip protrusions engage, completing the outlet protection and preventing debris from entering.

[0023] Working principle: The operator stands on one side of the push handle 23, releases the brake pads of the caster wheel 10, and pushes the handle to move the device within the seedling shed via the caster wheel until it reaches the target seedling area (such as next to the seedling rack). By rotating the control knob of the lifting hydraulic rod on the control panel 22, the lifting hydraulic rod 3 of the multiple stop devices is activated, and the output end extends to drive the support base plate 4 to descend until the anti-slip rubber strip 9 touches the ground and raises the bearing base 1, causing the caster wheel to leave the ground. The hydraulic rod is then closed, and the device is stably supported. Pull out the fixing pin 122 of the atomizing water sprayer 12, manually push the atomizing water sprayer to tilt and rotate around the rotation axis 121, adjust it to the target angle according to the height of the seedling rack, and then insert the fixing pin into the corresponding angle positioning hole 111 to lock the angle. Turn on the power switch on the operation control panel 22, press the start / stop button for the water supply pump 21. The water supply pump pressurizes the water in the water storage container 20 and sends it to the atomizing sprayer 12 through the delivery pipe. The atomizing sprayer sprays the water onto the seedlings to complete the irrigation. After the watering is finished, turn off the water supply pump, pull out the fixing pin, adjust the atomizing sprayer to a horizontal position, retract the lifting hydraulic rod to lower the casters to the ground, grasp the handle 19 of the anti-clogging cover, rotate the cover to cover the outlet and insert the fixing buckle 16, and finally push the device to the storage position and lock the caster brake pads.
