Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, specifically a rice seedling transfer device for rice planting. Background Technology

[0002] A rice seedling transfer device for rice cultivation is a piece of equipment used to transport and transfer rice seedlings during the rice planting process. It can conveniently and quickly transport seedlings from the seedling nursery to the planting area, effectively reducing the labor intensity of manual handling and improving the efficiency of seedling transfer. It can also be designed into different structural forms according to actual needs, such as handcart type, trailer type, etc., to adapt to rice seedling transfer tasks of different planting scales and planting environments.

[0003] A search revealed a rice seedling transfer device, as disclosed in publication number CN216684422U. This device includes a transfer box, a transport structure, and a seedling-carrying structure within the transfer box. The transport structure includes four sets of pulleys fixedly installed on the lower surface of the transfer box, two sets of guide rails located below the transfer box, and wheel grooves on the corresponding guide rails facing the transfer box. This transfer device enables directional transfer over a certain distance, meets the requirements for continuous transfer, and exhibits high orderliness in the transfer operation. The rice seedlings are arranged in an orderly manner, allowing for direct removal and use, and also meets the requirements for mobile transplanting. Furthermore, the device provides high protection during rice seedling transfer.

[0004] While the aforementioned device optimizes the effect of transporting rice seedlings, the seedlings gradually lose their stored water as they leave their original paddy fields and other growing environments. If they remain in a state of water shortage for a long time, the leaves will wither, turn yellow, or even die. The aforementioned device does not have the effect of spraying water on the rice seedlings, which will affect the survival rate of the rice seedlings during transport. Therefore, a rice seedling transport device based on rice planting is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a rice seedling transfer device for rice cultivation, which solves the problem of insufficient water spraying during the transfer process in existing technologies, thus affecting the survival rate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rice seedling transfer device for rice planting, comprising a transfer box, casters provided on the bottom outer wall of the transfer box, a water tank fixedly connected to the top outer wall of the transfer box, a water outlet pipe fixedly connected to the bottom outer wall of the water tank, a transfer mechanism provided on the inner wall of the transfer box, and a spraying mechanism provided on the outer wall of the transfer box.

[0007] The spraying mechanism includes a sprocket A, and a sprocket B is connected to the outer wall of the sprocket A via a chain drive. A fixing block is fixedly connected to the top outer wall of the transfer box. A rotating rod is fixedly connected to the outer wall of the sprocket B. A rotating shaft is slidably connected to the inner wall of the rotating rod. A groove is opened on the outer wall of the rotating shaft. A three-way ball valve is rotatably connected to the inner wall of the water outlet pipe. A connecting block is fixedly connected to the outer wall of the three-way ball valve. An insert block is elastically connected to the inner wall of the connecting block via a connecting spring.

[0008] Preferably, the sprocket A is fixedly connected to the outer wall of the caster, and the rotating rod passes through and is rotatably connected to the inner wall of the fixed block.

[0009] Preferably, one end of the connecting spring is fixedly connected to the outer wall of the insert block, and the other end of the connecting spring is fixedly connected to the inner wall of the connecting block.

[0010] Preferably, the outer wall of the insert block is slidably connected to the inner wall of the connecting block, and the insert block is engaged with the slot.

[0011] Preferably, the transfer mechanism includes a placement plate, the inner wall of which is elastically connected to a protrusion via a telescopic spring, the inner wall of which is slidably connected to a connecting rod, the inner wall of which is slidably connected to a trapezoidal block, and the inner wall of the transfer box is provided with a groove.

[0012] Preferably, the placement plate is in contact with the inner wall of the transfer box, one end of the telescopic spring is fixedly connected to the outer wall of the protrusion, the other end of the telescopic spring is fixedly connected to the inner wall of the placement plate, and the outer wall of the protrusion is slidably connected to the inner wall of the placement plate.

[0013] Preferably, one end of the connecting rod is fixedly connected to the outer wall of the protrusion, and the other end of the connecting rod is slidably connected to the outer wall of the trapezoidal block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention fixes the rotating shaft and connecting block by inserting a block and engaging a slot. When the transfer box is pushed, the caster drives the sprocket A, sprocket B, rotating rod, rotating shaft, connecting block, and three-way ball valve to rotate synchronously. This allows the three-way ball valve to control the opening and closing of the connection between the water tank and the outlet pipe, thus enabling intermittent water spraying into the transfer box. This avoids excessive water spraying that would make the environment too humid, or too little water spraying that would make it too dry, providing a suitable environment for the rice seedlings and ensuring their survival rate during transport.

[0022] 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.

[0023] like Figures 1 to 5 As shown, this utility model provides a rice seedling transfer device for rice planting, including a transfer box 1. Casters 4 are provided on the bottom outer wall of the transfer box 1. A water tank 5 is fixedly connected to the top outer wall of the transfer box 1. A water outlet pipe 6 is fixedly connected to the bottom outer wall of the water tank 5. A transfer mechanism 3 is provided on the inner wall of the transfer box 1, and a spraying mechanism 2 is provided on the outer wall of the transfer box 1. The spraying mechanism 2 includes a sprocket A201, and the outer wall of the sprocket A201 is connected to a chain 202. A fixed block 204 is fixedly connected to the top outer wall of the sprocket B203 and the transfer box 1. A rotating rod 205 is fixedly connected to the outer wall of the sprocket B203. A rotating shaft 206 is slidably connected to the inner wall of the rotating rod 205. A slot 207 is opened on the outer wall of the rotating shaft 206. A three-way ball valve 211 is rotatably connected to the inner wall of the water outlet pipe 6. A connecting block 208 is fixedly connected to the outer wall of the three-way ball valve 211. An insert block 210 is elastically connected to the inner wall of the connecting block 208 through a connecting spring 209.

[0024] The above scheme is adopted as follows: The transfer box 1 is the main body of the rice seedling transfer device for rice planting. When the transfer box 1 is pushed, it can be moved by the four sets of casters 4 below. The transfer mechanism 3 in the transfer box 1 can be used to place rice seedlings, and the position of the transfer mechanism 3 can be adjusted to accommodate rice seedlings of different heights to avoid putting pressure on them. The water tank 5 above the transfer box 1 contains water. During the transfer process, water can flow out from the water outlet pipe 6 and spray the rice seedlings through the nozzles set in the transfer box 1 via the water outlet pipe 6 to prevent them from lacking water during the transfer process and affecting their survival rate. The sprocket A201 is fixed to one of the sets of casters 4. When the transfer box 1 is pushed and the casters 4 rotate, the sprocket A201 will rotate accordingly. The transmission between sprocket B203 and chain 202 is a meshing transmission method, which is existing technology. Sprockets A201 and B203 are wheels with teeth. Chain 202 is a ring-shaped flexible component composed of multiple chain links. When caster 4 drives sprocket A201 to rotate, the teeth of sprocket A201 will mesh with the chain links of chain 202 one by one, and apply a tension to the chain, causing chain 202 to move with the rotation of sprocket A201. During the movement, the chain links will exert pressure on the teeth of sprocket B203, thereby driving sprocket B203 to rotate synchronously. When sprocket B203 rotates, the rotating rod 205 fixedly connected to its outer wall will also rotate around the rotation connection point with the fixed block 204. The fixed block 204 serves to support the rotating rod 205.

[0025] like Figures 3 to 4 As shown, sprocket A201 is fixedly connected to the outer wall of caster 4, and rotating rod 205 passes through and is rotatably connected to the inner wall of fixed block 204; one end of connecting spring 209 is fixedly connected to the outer wall of insert block 210, and the other end of connecting spring 209 is fixedly connected to the inner wall of connecting block 208; the outer wall of insert block 210 is slidably connected to the inner wall of connecting block 208, and insert block 210 is engaged with slot 207.

[0026] Using the above scheme: When the rotating rod 205 rotates, since the rotating shaft 206 can only move laterally within itself and cannot rotate, it will drive the rotating shaft 206 to rotate synchronously. A handle is provided on the outer wall of the rotating shaft 206; pulling the handle will drive the rotating shaft 206 to move laterally. When one end of the rotating shaft 206 is inserted into the connecting block 208, the connecting block 208 can be connected and fixed to the rotating shaft 206 and the rotating rod 205 through the snap-fit ​​relationship between the slot 207 and the insert block 210. The rotating rod 205 then drives the three-way ball valve 211 to rotate synchronously. Figure 2 and Figure 3As can be seen, the water outlet pipe 6 below the water tank 5 is designed in a right-angle shape, with a spherical pipe at the right angle. A three-way ball valve 211 is installed in the spherical pipe. When the three-way ball valve 211 rotates to the position where the through hole corresponds to the opening of the water tank 5 and the water outlet pipe 6, it connects the water tank 5 and the water outlet pipe 6, allowing water from the water tank 5 to flow into the water outlet pipe 6 and be sprayed from the nozzle into the transfer box 1. Conversely, when the three-way ball valve 211 rotates to the position where its outer wall corresponds to the opening of the water tank 5 and the water outlet pipe 6, it closes the opening, stopping the water spray. This achieves an automatic intermittent spraying effect during the movement of the transfer box 1, preventing prolonged spraying from causing excessive humidity inside the transfer box 1. Insufficient spraying volume leads to dryness inside the transfer box 1, affecting the survival rate of rice seedlings. During normal operation, the connecting spring 209 provides elastic force to the insert block 210 to stably engage with the slot 207, ensuring the reliability of the connection between the rotating shaft 206 and the connecting block 208. When no rice seedlings are placed in the transfer box 1, by pulling the insert block 210 to disengage it from the slot 207, the rotating shaft 206 can be moved laterally to disengage from the connecting block 208. In this state, when the rotating rod 205 and the rotating shaft 206 rotate, they will not drive the connecting block 208 and the three-way ball valve 211 to rotate, so that the water in the water tank 5 will not flow out from the outlet pipe 6, thus avoiding waste of water resources.

[0027] like Figure 2 and Figure 5 As shown, the transfer mechanism 3 includes a placement plate 301. A protrusion 303 is elastically connected to the inner wall of the placement plate 301 via a telescopic spring 302. A connecting rod 304 is slidably connected to the inner wall of the placement plate 301. A trapezoidal block 305 is slidably connected to the inner wall of the placement plate 301. A groove 306 is provided on the inner wall of the transfer box 1. The placement plate 301 contacts the inner wall of the transfer box 1. One end of the telescopic spring 302 is fixedly connected to the outer wall of the protrusion 303, and the other end of the telescopic spring 302 is fixedly connected to the inner wall of the placement plate 301. The outer wall of the protrusion 303 is slidably connected to the inner wall of the placement plate 301. One end of the connecting rod 304 is fixedly connected to the outer wall of the protrusion 303, and the other end of the connecting rod 304 is slidably connected to the outer wall of the trapezoidal block 305.

[0028] The above scheme is adopted: Placement plate 301 is used to place rice seedlings. Multiple sets of placement plates 301 can be placed in the transfer box 1. Through holes are provided on the outer wall of placement plate 301. Water sprayed by the nozzles flows downwards through the through holes after hitting the top placement plate 301, allowing the rice seedlings on each set of placement plates 301 to absorb water. Protrusions 303 and telescopic springs 302 are disposed on the inner walls of both sides of placement plate 301. When not affected by external force, protrusions 303 are held in a popped-out state by the elastic force of the telescopic springs 302 and engage with corresponding grooves 306, fixing placement plates 301 within the inner wall of the transfer box 1. At this time, protrusions 303 also drive corresponding connecting rods 304 to maintain contact with the long inclined surface of trapezoidal block 305. The connecting rod 304 can only move laterally within the inner wall of the placement plate 301. One outer wall of the trapezoidal block 305 is flush with the outer wall of the placement plate 301. The trapezoidal block 305 can be pressed inward, causing the connecting rod 304 to move along its long side slope to its short side slope, and driving the corresponding protrusion 303 to move into the inner wall of the placement plate 301, thereby causing the protrusion 303 to disengage from the groove 306, so that the placement plate 301 can be removed or its vertical position can be adjusted. The transfer box 1 is provided with multiple sets of sliding grooves for placing the placement plates 301. Adjusting the height between each set of placement plates 301 can accommodate rice seedlings that do not provide height, avoiding the problem that the upper placement plate 301 will bend the lower rice seedlings due to the rice seedlings being too tall.

[0029] Working principle and usage process of this utility model:

[0030] The operator can place the rice seedlings in a suitable position on the placement plate 301, press the trapezoidal block 305 in the placement plate 301 inward, so that the protrusions 303 on both sides move towards the middle, and insert the placement plate 301 into the transfer box 1. After it is fully inserted, release the trapezoidal block 305, and the telescopic spring 302 will cause the protrusions 303 on both sides to pop out and engage with the corresponding grooves 306, thus fixing the placement plate 301. Then, according to the height of the rice seedlings, install another set of placement plates 301 in a suitable position to prevent the rice seedlings from being bent, thus completing the placement of the rice seedlings.

[0031] After placement, pull the insert 210 upwards to compress the connecting spring 209, and pull the handle on the outer wall of the rotating shaft 206 to move the rotating shaft 206 laterally into the connecting block 208. Then release the insert 210, and the connecting spring 209 will cause the insert 210 to pop downwards, engaging with the slot 207. This connects and fixes the connecting block 208 to the rotating shaft 206 and the rotating rod 205. At this point, the transfer box 1 can be pushed, causing the caster 4 to rotate, which in turn drives the sprocket A201, which is fixedly connected to the outer wall of the caster 4, to rotate. The sprocket A201 is driven by the chain 202 and the sprocket B203, causing the sprocket B203 to rotate synchronously. When 203 rotates, it drives the rotating rod 205, rotating shaft 206, connecting block 208, and three-way ball valve 211 to rotate synchronously. When the three-way ball valve 211 rotates to the position where the through hole corresponds to the opening of the water tank 5 and the water outlet pipe 6, the water tank 5 and the water outlet pipe 6 are connected. The water in the water tank 5 flows into the water outlet pipe 6 and is sprayed from the nozzle into the transfer box 1 to spray the rice seedlings and prevent them from running out of water during the transfer process. When the three-way ball valve 211 rotates to the position where the outer wall corresponds to the opening of the water tank 5 and the water outlet pipe 6, the opening is closed and the water spraying stops. This achieves automatic intermittent spraying, so that too much or too little water spraying will not affect the rice seedlings.

[0032] When the transfer box 1 reaches its destination and no longer needs to spray water, the insert block 210 can be pulled to disengage it from the slot 207, and the rotating shaft 206 can be moved laterally to disengage from the connecting block 208. At this time, when the rotating rod 205 and the rotating shaft 206 rotate, they will not drive the connecting block 208 and the three-way ball valve 211 to rotate. The three-way ball valve 211 will close the opening of the water tank 5 and the outlet pipe 6, thus preventing water in the water tank 5 from flowing out of the outlet pipe 6 and causing water waste.
