Description

A seedling rack for tea cultivation Technical Field

[0001] This utility model relates to the field of tea planting technology, and in particular to a seedling rack for tea planting. Background Technology

[0002] Tea, commonly known as tea, generally includes the leaves and buds of the tea plant. Tea contains catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. Before planting tea plants, seedlings need to be cultivated. Once the seedlings have grown to a certain stage, they are transplanted. In the modern tea planting industry, the quality of tea seedling cultivation directly affects the yield and quality of subsequent tea. Sunlight is a key environmental factor for seedling growth and development, and its uniformity plays a decisive role in the growth status of the seedlings.

[0003] Currently, in order to reduce the land area and seedling cost, multi-layer seedling racks are usually used for seedling cultivation. However, traditional tea seedling racks mostly use fixed-layer structures, with the placement of seedlings on each layer being relatively fixed. As a result, under natural light, the upper seedlings closer to the light source receive sufficient light, while the seedlings at the bottom receive significantly insufficient light, resulting in uneven light distribution. Uneven light distribution can cause inconsistent growth and development among seedlings of the same batch. Some seedlings may suffer from leaf scorch and etiolation due to excessive light, while seedlings with insufficient light may have low photosynthetic efficiency, weak stems, and yellowing leaves, seriously affecting the overall quality and survival rate of the seedlings. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a seedling rack for tea cultivation.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a seedling rack for tea cultivation, comprising a frame body, on which several shelves are provided, a water pipe is fixedly connected to the frame body, and several nozzles are provided on the water pipes. A rotating structure is provided on the frame body, the rotating structure mainly consisting of four sprockets. The four sprockets are rotatably connected to the inner walls of both sides of the frame body through bearings. Two sprockets at the same height are fixedly connected by a round rod. Two sprockets on the same side are connected to a chain that meshes with each other. Several connecting shafts are fixedly connected to the chain. Connecting blocks are rotatably connected to the connecting shafts through bearings. The connecting blocks are fixedly connected to the shelves. A motor is fixedly connected to the frame body, and one of the sprockets is driven to rotate by the motor.

[0006] The aforementioned components achieve the following effects: Seedling trays are placed on the shelves, water pipes are connected to an external water source, and a liquid pump drives water into the pipes. Water is then applied through nozzles. The motor output is connected to a sprocket via a reducer and coupling. The motor model is 28BYJ-48. First, the power is turned on to power the motor control system. Then, starting the motor drives two sprockets to rotate. Under the action of the chain, four sprockets rotate synchronously, which in turn drives several connecting shafts to move with the chain, further changing the position of the shelves. This ensures that seedlings on different shelves receive even natural light, thus avoiding the situation where, due to the relatively fixed placement of seedlings on each layer, the upper seedlings closer to the light source receive sufficient light, while the seedlings at the bottom receive significantly insufficient light, resulting in uneven lighting and affecting the overall quality and survival rate of the seedlings.

[0007] Preferably, the shelf has a groove in which two L-shaped plates are slidably connected.

[0008] The effect achieved by the above components is that the size of the shelf can be changed by sliding the two L-shaped plates, so as to accommodate seedling pots of different sizes, and the two L-shaped plates can clamp and limit the two sides of the seedling pot.

[0009] Preferably, a bidirectional screw is threaded into both L-shaped plates, and the two threads on the bidirectional screw have opposite directions.

[0010] The effect achieved by the above components is that rotating the bidirectional screw can drive the two L-shaped plates to slide synchronously in opposite directions.

[0011] Preferably, a first bevel gear is fixedly connected to the bidirectional screw, a second bevel gear is meshed with the first bevel gear, and a knob is rotatably connected to the layer plate, the knob being fixedly connected to the second bevel gear.

[0012] The effect achieved by the above components is that the operator can rotate the knob to drive the second bevel gear to rotate, which in turn drives the first bevel gear to drive the bidirectional screw to rotate, making the adjustment operation more convenient.

[0013] Preferably, the frame is provided with a recycling structure, which mainly consists of a recycling bin, and the recycling bin is fixedly connected to the frame.

[0014] The effect achieved by the above components is that excess water during the watering process will fall into the recycling bin for collection, thus saving water resources.

[0015] Preferably, a filter plate is fixedly connected to the recycling bin, and the filter plate has a plurality of filter holes.

[0016] The effect achieved by the above components is that the filter holes on the filter plate have a large diameter, which can isolate larger waste and prevent waste from entering the recycling bin.

[0017] Preferably, an inclined plate is fixedly connected to the recycling bin, and a sedimentation tank is provided in the recycling bin.

[0018] The effect achieved by the above components is that some fine mud and sand enter the recycling bin, and the inclined plate guides them into the sedimentation tank for sedimentation, which facilitates the sedimentation operation.

[0019] Preferably, a water pump is fixedly connected to the frame, a delivery pipe is fixedly connected to the output end of the water pump, the delivery pipe is fixedly connected to a water pipe, the input end of the water pump is fixedly connected to a recycling tank, and a filter screen is fixedly connected to the input end of the water pump.

[0020] The effects achieved by the above components are as follows: when the water pump is started, the water pump can pump the water collected in the recycling tank to the water pipe through the delivery pipe for re-irrigation; the filter screen has a small pore size, which can filter out mud and sand and prevent mud and sand from entering the water pump and causing damage.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a rotating structure, the seedling pot is placed on the shelf, the water pipe is connected to the external water source, and the water source is driven into the water pipe by a liquid pump, and then water is applied through the nozzle. The output end of the motor is connected to the sprocket through a reducer and a coupling. The motor model is 28BYJ-48. First, the power is turned on to power the motor control system, and then the motor is started to drive the two sprockets to rotate. Under the action of the chain, the four sprockets rotate synchronously, which in turn drives several connecting shafts to move with the chain, further changing the position of the shelf. This allows the seedlings on different shelves to receive natural light evenly, thus avoiding the situation where the placement position of each layer of seedlings is relatively fixed. Under natural light, the upper seedlings closer to the light source receive sufficient light, while the seedlings at the bottom receive significantly insufficient light, resulting in uneven light exposure, which affects the overall quality and survival rate of the seedlings.

[0028] Example 1, as shown in Figure 1, is a seedling rack for tea cultivation, including a frame 1, several layers 2 on the frame 1, a water pipe 3 fixedly connected to the frame 1, and several nozzles 4 on the water pipe 3.

[0029] Referring to Figures 1 to 3, a rotating structure 5 is provided on the frame 1. The rotating structure 5 mainly consists of four sprockets 51. The four sprockets 51 are rotatably connected to the inner walls of both sides of the frame 1 via bearings. Two sprockets 51 at the same height are fixedly connected by a round rod. A chain 52 is meshed with two sprockets 51 on the same side. Several connecting shafts 53 are fixedly connected to the chain 52. Connecting blocks 54 are rotatably connected to the connecting shafts 53 via bearings. The connecting blocks 54 are fixedly connected to the shelf 2. A motor 55 is fixedly connected to the frame 1. One sprocket 51 is driven to rotate by the motor 55. Place the seedling trays on shelf 2, connect water pipe 3 to an external water source, and drive water into water pipe 3 via a liquid pump. Water is then applied through nozzle 4. The output of motor 55 is connected to sprocket 51 via a reducer and coupling. Motor 55 is model 28BYJ-48. First, connect the power supply to power the motor 55 control system. Then, start motor 55 to drive two sprockets 51 to rotate. Under the action of chain 52, all four sprockets 51 rotate synchronously, thereby driving several connecting shafts 53 to move with chain 52, further changing the position of shelf 2, so that seedlings on different shelves 2 can be watered. The seedlings are evenly exposed to natural light, thus avoiding the uneven lighting situation where the seedlings on the upper layer, closer to the light source, receive sufficient light while the seedlings on the lower layer receive insufficient light, which affects the overall quality and survival rate of the seedlings. The layer 2 has a sliding groove 56, through which two L-shaped plates 57 are slidably connected. The size of the layer 2 can be changed by sliding the two L-shaped plates 57, thus accommodating seedling pots of different sizes. Furthermore, the two L-shaped plates 57 can clamp and limit the seedling pots on both sides. A bidirectional screw 58 is threaded into the common thread of the template 57. The two threads on the bidirectional screw 58 are in opposite directions. Rotating the bidirectional screw 58 can drive the two L-shaped plates 57 to slide synchronously in opposite directions. A first bevel gear 59 is fixedly connected to the bidirectional screw 58. A second bevel gear 510 is meshed with the first bevel gear 59. A knob 511 is rotatably connected to the shelf 2. The knob 511 is fixedly connected to the second bevel gear 510. The operator can rotate the knob 511 to drive the second bevel gear 510 to rotate, which in turn causes the first bevel gear 59 to drive the bidirectional screw 58 to rotate, making the adjustment operation more convenient.

[0030] Referring to Figures 2 and 4, a recycling structure 6 is installed on the frame 1. The recycling structure 6 mainly consists of a recycling bin 61, which is fixedly connected to the frame 1. During watering, excess water will fall into the recycling bin 61 for collection, saving water. A filter plate 62 is fixedly connected to the recycling bin 61. The filter plate 62 has several filter holes with a relatively large aperture, which can isolate larger waste and prevent it from entering the recycling bin 61. An inclined plate 63 is fixedly connected to the recycling bin 61. A sedimentation tank 64 is provided in the recycling bin 61, allowing some fine silt and sand to enter the recycling bin 61. The water is guided into the sedimentation tank 64 for sedimentation, facilitating the sedimentation process. A water pump 65 is fixedly connected to the frame 1, and a delivery pipe 66 is fixedly connected to the output end of the water pump 65. The delivery pipe 66 is fixedly connected to the water pipe 3. The input end of the water pump 65 is fixedly connected to the recycling tank 61, and a filter screen 67 is fixedly connected to the input end of the water pump 65. When the water pump 65 is started, it can pump the water collected in the recycling tank 61 to the water pipe 3 through the delivery pipe 66 for re-irrigation. The filter screen 67 has a small pore size, which can filter the sediment and prevent it from entering the water pump 65 and causing damage.

[0031] Working principle: Seedling trays are placed on shelf 2, water pipe 3 is connected to an external water source, and water is pumped into water pipe 3 and then watered through nozzle 4. The output of motor 55 is connected to sprocket 51 via a reducer and coupling. Motor 55 is model 28BYJ-48. First, the power is turned on to power the motor 55 control system. Then, starting motor 55 drives two sprockets 51 to rotate. Under the action of chain 52, four sprockets 51 rotate synchronously, which in turn drives several connecting shafts 53 to move with chain 52, further changing the position of shelf 2. This allows the seedlings on different shelves 2 to receive natural light evenly, thus avoiding the uneven lighting phenomenon caused by the relatively fixed placement of seedlings on each layer. Seedlings on the upper layer closer to the light source receive sufficient light, while seedlings on the lower layer receive insufficient light, which affects the overall quality and survival rate of the seedlings. The size of shelf 2 can be changed by sliding two L-shaped plates 57. For seedling pots of different sizes, two L-shaped plates 57 can clamp and limit the two sides of the seedling pot. Rotating the bidirectional screw 58 can drive the two L-shaped plates 57 to slide synchronously in opposite directions. The operator can rotate the knob 511 to drive the second bevel gear 510 to rotate, which in turn drives the first bevel gear 59 to drive the bidirectional screw 58 to rotate, making the adjustment operation more convenient. During the watering process, excess water will fall into the recycling bin 61 for collection, which can save water. The filter holes on the filter plate 62 have a large diameter, which can isolate larger garbage and prevent garbage from entering the recycling bin 61. Some fine mud and sand enter the recycling bin 61, and the inclined plate 63 will guide them to enter the sedimentation tank 64 for sedimentation, which facilitates the sedimentation operation. Start the water pump 65, and the water pump 65 can pump the water collected in the recycling bin 61 to the water pipe 3 through the delivery pipe 66 for re-watering. The filter screen 67 has a small diameter filter hole, which can filter mud and sand and prevent mud and sand from entering the water pump 65 and causing damage.
