Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice planting technology, and in particular to a rice seedling transport device for rice planting. Background Technology
[0002] Rice is an annual aquatic herbaceous plant belonging to the genus Oryza in the family Poaceae. It is an important food crop worldwide, and its hulled grains are called rice. Rice seedlings need to be transported during cultivation, thus requiring specialized transport equipment.
[0003] Existing methods typically involve placing rice seedlings directly in net frames for transportation. During transport, factors such as sunlight, temperature increases, and airflow can cause the rice seedlings to lose moisture through the stomata on their leaf surfaces. Furthermore, existing devices lack an integrated structure to retain moisture in the seedlings, which reduces their survival rate during transport. Therefore, we provide a rice seedling transport device for rice cultivation. Utility Model Content
[0004] To address the problem in the background art that the survival rate of rice seedlings is easily affected by water evaporation during transportation, this utility model provides a rice seedling transportation device for rice planting.
[0005] This utility model is achieved by the following technical solution: a rice seedling transport device for rice planting, including a vehicle body and a covering component, wherein a placement frame is fixedly connected to the top of the vehicle body.
[0006] The covering assembly includes a lead screw rotatably connected to one side of the top of the vehicle body via a connecting frame 1. A threaded block is threadedly connected to the outside of the lead screw. A guide rod is fixedly connected to the other side of the top of the vehicle body via a connecting frame 2. A guide block is slidably connected to the outside of the guide rod. A connecting seat is fixedly connected between the guide block and the threaded block. A roller is rotatably connected to the connecting seat via a rotating shaft. A fixing plate is fixedly connected to the top of the placement frame. A film is fixedly connected to the fixing plate, and the end of the film is wound around the outside of the roller. A gear is coaxially fixedly connected to one end of the rotating shaft. The same rack is fixedly connected to both sets of connecting frames 2, and the rack and gear are meshed together.
[0007] As a further improvement to the above solution, a brush plate is provided above the roller, and brush bristles are evenly fixedly connected to the bottom of the brush plate. Two sets of vertical rods are symmetrically fixedly connected to the top of the brush plate, and the vertical rods are slidably connected to the connecting seat. Springs are sleeved on the outside of the vertical rods.
[0008] As a further improvement to the above solution, the placement frame is provided with evenly spaced ventilation holes.
[0009] As a further improvement to the above solution, a motor is fixedly connected to the first bracket, and the end of the motor rotor is coaxially fixedly connected to one end of the lead screw. A battery is also fixedly connected to the top of the vehicle body, and the battery is electrically connected to the motor.
[0010] As a further improvement to the above solution, the width of the film is matched with the width of the top opening of the placement frame.
[0011] As a further improvement to the above solution, a limit plate is fixedly connected to the top of both sets of vertical rods.
[0012] As a further improvement to the above solution, the two ends of the spring are fixedly connected to the connecting seat and the brush plate, respectively.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model uses a motor to drive a lead screw to rotate. The screw is connected to the threaded block, and the guide block and guide rod are connected in a sliding manner. The guide block and threaded block are fixedly connected to the connecting seat. This allows the connecting seat to move horizontally. The movement of the connecting seat can drive the roller to move, and the movement of the roller can drive the gear to move. The meshing action between the gear and the rack allows the roller to rotate while moving horizontally. This allows the film to be spread on top of the placement frame to cover the rice seedlings, thereby keeping them moist and preventing water evaporation. Conversely, the film can be rolled up to remove the rice seedlings.
[0015] 2. In the process of the motor driving the lead screw to reverse so that the roller can wind the film, the brush plate and brush bristles can sweep away the soil adhering to the rice seedlings on the surface of the film, thereby preventing the soil from affecting the winding of the film. Furthermore, through the rebound of the spring itself and the sliding cooperation between the vertical rod and the connecting seat, the brush bristles can always be in contact with the surface of the film, thus ensuring the cleaning effect on the surface of the film and making it highly practical.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0022] Example 1:
[0023] Please combine Figure 1-3 This embodiment of a rice seedling transport device for rice planting includes a vehicle body 1, with a placement frame 2 fixedly connected to the top of the vehicle body 1. The placement frame 2 has evenly spaced ventilation holes to ensure air permeability during transportation and prevent carbon dioxide accumulation that could lead to the death of rice seedlings.
[0024] A covering assembly for moisturizing rice seedlings includes a lead screw 101 rotatably connected to one side of the top of a vehicle body 1 via a connecting frame 1. A threaded block 102 is threaded onto the outside of the lead screw 101. A guide rod 103 is fixedly connected to the other side of the top of the vehicle body 1 via a connecting frame 2. A guide block 104 is slidably connected to the outside of the guide rod 103. A connecting seat 105 is fixedly connected between the guide block 104 and the threaded block 102. A roller 106 is rotatably connected to the connecting seat 105 via a rotating shaft. A fixing plate 107 is fixedly connected to one side of the top of a placement frame 2. A film 10 is fixedly connected to the fixing plate 107. 8. The end of the film 108 is wound around the outside of the roller 106. One end of the rotating shaft is coaxially fixedly connected to the gear 109. The same rack 110 is fixedly connected to the two sets of connecting frames 2 and the rack 110 meshes with the gear 109. A motor is fixedly connected to the connecting frame 1 and the end of the motor rotor is coaxially fixedly connected to one end of the lead screw 101. A battery is also fixedly connected to the top of the vehicle body 1 and is electrically connected to the motor, which can provide power to drive the lead screw 101 to rotate. The width of the film 108 matches the width of the top opening of the placement frame 2, which can completely cover the top opening of the placement frame 2.
[0025] A brush plate 201 is provided above the roller 106. Brush bristles 202 are evenly fixedly connected to the bottom of the brush plate 201. Two sets of vertical rods 203 are symmetrically fixedly connected to the top of the brush plate 201, and the vertical rods 203 are slidably connected to the connecting seat 105. A spring 204 is sleeved on the outside of the vertical rod 203. The two ends of the spring 204 are fixedly connected to the connecting seat 105 and the brush plate 201, respectively.
[0026] The implementation principle of a rice seedling transport device for rice planting in this embodiment is as follows: First, the rice seedlings are evenly placed inside the placement frame 2. Then, the motor is started, driving the lead screw 101 to rotate. Through the threaded connection between the lead screw 101 and the threaded block 102, the sliding connection between the guide block 104 and the guide rod 103, and the fixed connection between the guide block 104, the threaded block 102, and the connecting seat 105, the connecting seat 105 can be moved horizontally. The movement of the connecting seat 105 in turn drives the roller 106 to move, which in turn drives the gear 109 to move. Utilizing the meshing between the gear 109 and the rack 110, the roller 106 can rotate while moving horizontally, thereby spreading the film 108 on top of the placement frame 2 to cover the rice seedlings and thus retain moisture. The purpose is to prevent moisture evaporation. As the pusher body 1 moves, it transports rice seedlings. When it reaches the designated location, the control motor drives the lead screw 101 to rotate in the opposite direction. At this time, the roller 106 will roll up the film 108 to open the placement frame 2. At the same time, as the motor drives the lead screw 101 to reverse so that the roller 106 can roll up the film 108, the brush plate 201 and brush bristles 202 can sweep away the soil adhering to the rice seedlings on the surface of the rolled film 108, thereby preventing the soil from affecting the rolling of the film 108. Furthermore, through the rebound of the spring 204 and the sliding cooperation between the vertical rod 203 and the connecting seat 105, the brush bristles 202 can always be in contact with the surface of the film 108, thereby ensuring the cleaning effect of the surface of the film 108. Finally, the rice seedlings can be taken out one by one.
[0027] Example 2:
[0028] Based on Embodiment 1, this embodiment is further improved in that: the top ends of both sets of vertical rods 203 are fixedly connected to limit plates 205, which can prevent the vertical rods 203 from separating from the connecting seat 105.
