Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a high-speed rice transplanter seedling pre-humidification device. Background Technology

[0002] The seedling delivery device of a high-speed rice transplanter is an indispensable and important component of modern agricultural mechanization, designed to efficiently and accurately deliver and implant seedlings into the soil. Its main function is to mechanically deliver seedlings from seedling trays to the transplanting position.

[0003] Chinese patent CN212993008U discloses a "longitudinal seedling delivery device for a high-speed rice transplanter with a pot-shaped blanket-like seedling". This device for delivering longitudinal seedlings with a pot-shaped blanket-like seedling in a high-speed rice transplanter uses multiple longitudinal guide strips on the inner bottom wall of the delivery platform to support and laterally position the pot when the blanket-shaped seedlings are placed in. When the seedlings move laterally with the delivery platform, there is no cumulative error caused by lateral movement. A transverse trapezoidal positioning strip is set on the surface of the longitudinal delivery belt to longitudinally position the blanket-shaped seedlings. This ensures that when the seedlings are delivered intermittently with the delivery belt, they are delivered into the seedling tray one row at a time, preventing accumulation due to relative longitudinal displacement. This avoids squeezing of the seedlings, improves the accuracy of seedling delivery, and better ensures the efficiency of seedling delivery.

[0004] During the seedling delivery process, seedlings pass through multiple stages, including delivery platforms and conveyor belts, exposing them to air. If the environment is dry or the delivery time is prolonged, the seedlings' roots and pots lose moisture, causing them to dry out. This process doesn't consider how to replenish water in a timely manner. If seedlings lack water during transportation and delivery, root moisture will rapidly evaporate, leading to desiccation and affecting their survival rate. This is especially true for potted, mat-like seedlings, which typically rely on soil moisture and a moist root environment to maintain vitality and growth.

[0005] In view of this, we propose a high-speed rice transplanter delivery device for pre-humidifying seedlings. Utility Model Content

[0006] The purpose of this utility model is to provide a high-speed rice transplanter seedling pre-humidification device, which solves the problem that the seedlings lose moisture rapidly from their roots during the seedling delivery process, thus affecting their survival rate.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-speed rice transplanter seedling pre-humidification device includes a seedling delivery mechanism comprising a seedling delivery platform, a seedling pressing rod, an electric seedling delivery belt, and a seedling taking port. A pre-humidification mechanism is installed on the seedling delivery platform, comprising: a support frame, one end of which is fixedly connected to the outer wall of the seedling delivery platform; a water supply pipe fixedly connected to the other end of the support frame; a nozzle rotatably connected to one end of the water supply pipe; an angled nozzle fixedly connected to the inner wall of the nozzle; a water pump fixedly connected to the other end of the water supply pipe; a telescopic pipe fixedly connected to the bottom of the water pump; and a suction head fixedly connected to the bottom of the telescopic pipe for drawing water. A filtration mechanism is installed on the suction head for filtering the incoming water.

[0009] Preferably, the seedling delivery platform is equipped with a seedling pressing rod, the bottom of the seedling delivery platform is equipped with an electric seedling delivery belt, and the side of the seedling delivery platform is equipped with a seedling taking port.

[0010] Preferably, the angled nozzles are obliquely disposed on the inner wall of the nozzle, and multiple angled nozzles are disposed in an array on the nozzle.

[0011] Preferably, the water pump is fixedly connected to the outer wall of the seedling delivery platform for supporting and fixing the water pump.

[0012] Preferably, the filtration mechanism includes a hollow cylindrical block, which is fixedly connected to the outer wall of the suction head, and a filter screen is fixedly connected to the bottom of the hollow cylindrical block. The filter screen is used to filter the water entering the suction head.

[0013] Preferably, the hollow cylindrical block is provided with a support base at its bottom, the support base being used to support the hollow cylindrical block.

[0014] Preferably, an impeller is rotatably connected to the inner wall of the hollow cylindrical block, and a fan-shaped hollow component and a strip-shaped hollow component are fixedly connected to the shaft of the impeller. The fan-shaped hollow component is located on the side of the filter screen closer to the suction head, and the strip-shaped hollow component is located on the side of the filter screen away from the suction head.

[0015] By employing the above technical solution, this utility model provides a high-speed rice transplanter seedling pre-humidification device. It possesses at least the following beneficial effects:

[0016] 1. This utility model incorporates a pre-humidification mechanism. The suction head is placed in a water source, such as a bucket. The water pump is then turned on, and the water is sprayed at an angle through rotating nozzles. This allows the water to be sprayed more evenly onto the seedlings, preventing over-humidification in some areas while under-humidification in others. This ensures that the entire seedling area receives relatively uniform humidity. During the seedling delivery process, even humidification helps maintain the overall moisture balance of the seedlings and prevents uneven water distribution.

[0017] 2. This utility model incorporates a filtration mechanism, so that when the suction head draws in water, the water in the water source is filtered through the filter screen.

[0018] 3. This utility model incorporates a filtration mechanism. Water flowing in the opposite direction through the strip-shaped portion of the fan-shaped hollow component washes over the filter screen, causing impurities on the screen to enter the inner wall of the hollow component. Under the action of the rotating impeller, the hollow component uses centrifugal force to throw the impurities out. This achieves both filtration and impurity removal. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 - Figure 9 As shown, this utility model provides a technical solution: a high-speed rice transplanter seedling pre-humidification device, including a seedling delivery device 1. The seedling delivery device 1 includes a seedling delivery platform 11, a seedling pressing rod 12, an electric seedling delivery belt 13, and a seedling taking port 14. A pre-humidification mechanism 2 is provided on the seedling delivery platform 11. The pre-humidification mechanism 2 includes a support frame 21, one end of which is fixedly connected to the outer wall of the seedling delivery platform 11, and the other end of which is fixedly connected to a water supply pipe 22. One end of the water supply pipe 22 is rotatably connected to a nozzle 23. An angled nozzle 27 is fixedly connected to the inner wall of the head 23. A water pump 24 is fixedly connected to the other end of the water supply pipe 22. A telescopic pipe 25 is fixedly connected to the bottom of the water pump 24. A suction head 26 is fixedly connected to the bottom of the telescopic pipe 25. The suction head 26 is used to draw water. A filter mechanism 3 is provided on the suction head 26. The filter mechanism 3 is used to filter the incoming water. A seedling pressing rod 12 is provided on the seedling delivery platform 11. The seedling delivery platform 11 is the basic platform for placing seedlings, providing a stable place for the seedlings and playing a role in the entire seedling delivery process. The seedling conveying platform 11 serves as the initial carrier for seedling movement, ensuring that the seedlings are transported according to the predetermined process. The pressing rod 12 presses down on the seedlings to prevent them from shifting or swaying due to vibration or other factors during delivery, ensuring they are in the correct position for accurate subsequent seedling removal. An electric seedling conveying belt 13 is installed at the bottom of the conveying platform 11. This belt is the power actuator for seedling delivery, driven by electricity, and operates at a set speed and rhythm. The seedlings placed on the seedling delivery platform 11 move forward to transport the seedlings, gradually transporting them from the starting position of the seedling delivery platform 11 to the seedling taking port 14, thus continuously supplying seedlings for transplanting operations. The seedling delivery platform 11 has a seedling taking port 14 on its side. An inclined nozzle 27 is inclinedly set on the inner wall of the nozzle 23. Multiple inclined nozzles 27 are arranged in an array on the nozzle 23. A water pump 24 is fixedly connected to the outer wall of the seedling delivery platform 11 to support and fix the water pump 24.

[0032] The filtration mechanism 3 includes a hollow cylindrical block 31, which is fixedly connected to the outer wall of the suction head 26. A filter screen 36 is fixedly connected to the bottom of the hollow cylindrical block 31. The filter screen 36 is used to filter the water entering the suction head 26. A support base 32 is provided at the bottom of the hollow cylindrical block 31 to support the hollow cylindrical block 31, so that the filter screen 36 can smoothly absorb water. An impeller 33 is rotatably connected to the inner wall of the hollow cylindrical block 31. A fan-shaped hollow component 34 and a strip-shaped hollow component 35 are fixedly connected to the shaft of the impeller 33. The fan-shaped hollow component 34 is located on the side of the filter screen 36 closer to the suction head 26, and the strip-shaped hollow component 35 is located on the side of the filter screen 36 away from the suction head. On one side of 26, when external water passes through the filter screen 36, the water enters the arc-shaped part of the fan-shaped hollow component 34, and then enters the part of the fan-shaped hollow component 34 and the strip-shaped hollow component 35 that are directly opposite each other. This causes the part of the fan-shaped hollow component 34 and the strip-shaped hollow component 35 that are directly opposite each other to form a reverse impact water. At this time, the strip-shaped hollow component 35 is directly opposite the strip-shaped part of the fan-shaped hollow component 34, so that the reverse impact water is not affected by the water flowing into the filter screen 36. The water flowing in the reverse direction in the strip-shaped part of the fan-shaped hollow component 34 washes the filter screen 36, causing the impurities on the filter screen 36 to enter the inner wall of the strip-shaped hollow component 35. Under the action of the impeller 33 rotating, the strip-shaped hollow component 35 uses centrifugal force to throw out the impurities.

[0033] This utility model discloses a high-speed rice transplanter seedling pre-humidification device. In use, the suction head 26 is placed in a water source (e.g., a bucket), and the water pump 24 is turned on. The pump 24 drives water through the suction head 26, telescopic pipe 25, water delivery pipe 22, and nozzle 23, finally spraying it out through the angled nozzle 27. The opposing force generated by the angled nozzle 27 during spraying causes the nozzle 23 to rotate, thus pre-humidifying the seedlings. The rotation of the angled nozzle 27 changes the angle and range of the spray. Compared to a fixed nozzle spraying water in a single direction, the rotating spray allows water to be more evenly distributed on the seedlings, preventing over-humidification in some areas and under-humidification in others, ensuring a more uniform humidity level across the entire seedling area. During seedling delivery, even humidification helps maintain the overall moisture balance of the seedlings and prevents uneven moisture distribution.

[0034] When the suction head 26 draws in water, the water in the water source is filtered through the filter screen 36.

[0035] At this time, water flows through impeller 33, which rotates under the action of water flow. Impeller 33 drives the fan-shaped hollow component 34 and the strip-shaped hollow component 35 to rotate, causing the parts of the fan-shaped hollow component 34 and the strip-shaped hollow component 35 facing each other to form a reverse impact water flow. At this time, the strip-shaped hollow component 35 is exactly opposite to the strip-shaped part of the fan-shaped hollow component 34, so that the reverse impact water here is not affected by the water flowing into the filter screen 36. The water flowing in the reverse direction on the strip-shaped part of the fan-shaped hollow component 34 washes the filter screen 36, causing impurities on the filter screen 36 to enter the inner wall of the strip-shaped hollow component 35. Under the action of impeller 33 rotation, the strip-shaped hollow component 35 uses centrifugal force to throw out the impurities. This achieves the function of filtering and removing impurities at the same time.
