Description

Technical Field

[0001] This utility model relates to the field of rice planting technology, and in particular to a germination device for rice seed production. Background Technology

[0002] Germination equipment for rice seed production is a key piece of equipment to ensure the germination rate and quality of seeds. It provides suitable environmental conditions for the seeds, such as temperature, humidity, and moisture, to improve production efficiency and seed quality. During the rice seed germination process, turning the seeds over can effectively prevent seed accumulation and mold, and ensure that the seeds are evenly moistened and aerated.

[0003] However, existing rice seed germination equipment has some shortcomings in use. For example, turning the seeds on the tray is mostly done manually, which is not only inefficient but also easily damages the seed embryos. It also easily leads to frequent opening of the sealed door, which disrupts the internal temperature and humidity stability. In some equipment, the seed tray is fixed, making it inconvenient to pick up and put down the seeds and increasing the difficulty of operation. Therefore, we propose a rice seed germination equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as low efficiency and easy damage to the embryo caused by manually turning the seeds, frequent opening of the box disrupting temperature and humidity stability, and inconvenience and difficulty in operation due to the fixed placement tray. Therefore, this invention proposes a germination device for rice seed production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rice seed germination device, including a cultivation box,

[0007] The opening of the cultivation box is hinged with a sealing door, and multiple sets of support components are fixedly installed inside. Each set of support components has a placement tray that slides on it.

[0008] The placement tray is equipped with a flipping component, which includes a sliding moving rod and a rotating tube rotatably sleeved on it;

[0009] The top and bottom inner walls of the cultivation box are both provided with grooves, and connecting blocks are slidably connected in the two grooves respectively. A movable tube is fixedly connected between the two connecting blocks.

[0010] The movable tube passes through the fixed block, the fixed block has a positioning hole, and one end of the movable rod extends to the outside of the placement plate and is detachably inserted into the positioning hole;

[0011] When the moving tube moves horizontally, the moving rod slides through the fixed block, and the rotating tube rotates through the transmission component to achieve automatic replanting;

[0012] The sealed door has a viewing window, which is fixed with a double-layer transparent acrylic panel.

[0013] In one possible design, the support assembly includes two support plates fixed to the inner walls of both sides of the cultivation box, with a first sliding groove opened on the top of each support plate; the bottom of the placement tray is provided with two limiting rods, which are slidably connected to the corresponding first sliding grooves.

[0014] In one possible design, one of the support plates has a sliding cavity on its side, in which a limiting pin is slidably disposed, one end of which extends into a first sliding groove to lock the limiting rod.

[0015] In one possible design, the transmission assembly includes a gear fixedly sleeved on a rotating tube, a plurality of soft flipping rods on the outer wall of the rotating tube, a transmission groove on one side inner wall of the placement tray, a rack fixedly connected to the top inner wall of the transmission groove, the rack meshing with the gear, a second sliding groove on both sides inner walls of the placement tray, and two sliders on the moving rod, the two sliders respectively slidingly engaging with the corresponding second sliding groove.

[0016] In one possible design, a spray pipe is fixedly installed on the outer wall of the movable pipe, which communicates with the movable pipe and extends above the placement tray; the bottom of the spray pipe is connected to multiple nozzles, and the movable pipe is connected to an external water source via a connecting hose.

[0017] In one possible design, the drive assembly includes a slide rod fixed to a bottom groove, with a lower connecting block sliding through the slide rod; a lead screw rotatably connected in a top groove, with an upper connecting block threaded into the lead screw; and the motor output connected to the lead screw via a right-angle steering gear.

[0018] In one possible design, monitoring components, including humidity sensors and temperature sensors, are fixedly installed on the inner walls of both sides of the cultivation chamber, and the two monitoring components are staggered in the vertical direction.

[0019] In one possible design, a dehumidifier is fixedly installed on the top of the cultivation chamber, and its dehumidification port is connected to the interior of the cultivation chamber.

[0020] In one possible design, heating plates are embedded and fixed on both inner walls of the cultivation chamber.

[0021] In one possible design, one side of the cultivation chamber is connected to a drain pipe, which is equipped with a solenoid valve.

[0022] In this application, when the rice seed germination device is needed, first open the sealed door, place the rice seeds on the placement tray, then move the limiting pin away from the first slide groove, then slide the placement tray in the first slide groove of the support assembly through the limiting rod, and move the limiting pin again so that its surface contacts one side of the limiting rod to limit the position of the placement tray, ensuring that the placement tray is stably located in the cultivation box. At this time, one end of the moving rod on the placement tray is inserted into the positioning hole of the fixing block on the moving tube.

[0023] Next, start the motor of the drive assembly. The motor drives the lead screw to rotate through the right-angle steering gear, so that the upper connecting block moves on the lead screw, while the lower connecting block slides on the slide rod, thereby driving the moving tube to move in the cultivation box. When the moving tube moves, the spray pipe of the spray assembly moves to the top of the corresponding placement tray and is connected to the external water source through the connecting hose. Water is sprayed out from the nozzle to spray the seeds.

[0024] During the spraying process, the fixed block on the moving tube moves with the moving tube, causing the moving rod to slide in the second groove of the placement tray. Since the rotating tube is mounted on the moving rod, when the moving rod slides, the gear on the rotating tube meshes with the rack on the inner wall of the top of the second groove, causing the rotating tube to rotate on the moving rod, thus realizing the turning rod on the rotating tube turning the seeds in the placement tray.

[0025] Meanwhile, the humidity and temperature sensors of the monitoring components monitor the humidity and temperature inside the cultivation box in real time. When the humidity is high, the dehumidifier is activated to extract the moisture from the box through the dehumidification port; when the temperature is low, the heating plate is activated to heat the box, ensuring that the environmental conditions inside the box are suitable for seed germination.

[0026] In addition, staff can observe the germination of seeds inside the box through the viewing window on the sealed door, and the drainage pipe can be used to drain the accumulated liquid in the cultivation box in a timely manner.

[0027] Beneficial effects: In this utility model, the rice seed germination equipment is equipped with a turning component. When the moving tube moves, it drives the moving rod and the gear rack to mesh and transmit the automatic turning of the seeds by the rotating tube. This eliminates the need to frequently open the sealed door, which avoids the risk of germ damage caused by manual turning and improves turning efficiency.

[0028] In this utility model, a rice seed germination device is described. When the moving tube is driven by the drive component, the spray component simultaneously replenishes water and turns the tube. The monitoring component adjusts the temperature and humidity in real time to reduce temperature and humidity fluctuations inside the box and effectively maintain the stability of the cultivation environment.

[0029] In this utility model, the rice seed germination device adopts a sliding connection structure between the limiting rod and the first sliding groove through the support component. The placement tray can be directly pulled out or pushed in along the sliding groove, and the limiting pin can lock the position of the placement tray, which not only ensures the stability during cultivation, but also solves the problem of inconvenience in taking out and putting in the fixed placement tray, and reduces the difficulty of operation.

[0030] In this invention, the rotating tube automatically flips the seeds through the flipping component, avoiding manual damage to the germ and improving efficiency, and eliminating the need to frequently open the sealed door; when the driving component moves the moving tube, the spraying and flipping are synchronized, and the monitoring component adjusts the temperature and humidity to reduce fluctuations in the environment inside the box; the sliding connection structure of the support component makes it easy to pull out or push in the placement tray, and the limit pin locks the position, solving the problem of inconvenient picking and placing.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0040] Example 1: Refer to Figure 1-7 A germination device includes a cultivation box 1 with a hinged sealing door 16 at its opening. A viewing window 21, constructed of double-layered transparent acrylic panels, allows for real-time observation of the internal germination process and provides heat insulation. Multiple support components 2 are equidistantly arranged vertically inside the cultivation box 1. Each support component 2 consists of two symmetrically welded support plates 2 to the inner wall of the box. A first sliding groove 201 is formed on the top surface of each support plate 2, allowing two limiting rods 301 at the bottom of a placement tray 3 to slide along the groove for horizontal positioning. A sliding cavity is formed on the side wall of one of the support plates 2, housing a retractable limiting pin 202. When the placement tray 3 is pushed into place, the sliding limiting pin 202 causes its end to press against the limiting rod 301 for mechanical locking.

[0041] Each placement tray 3 is equipped with a flipping assembly, specifically structured as follows: The moving rod 4 is fitted into a second sliding groove on the inner wall of the placement tray 3 via sliders at both ends. A rotating tube 5 is rotatably sleeved around the moving rod 4 via bearings. Multiple sets of silicone flipping rods are evenly distributed on the outer wall of the rotating tube 5. A gear 6 is fixedly mounted on the rotating tube 5, meshing with a rack 7 welded into a transmission groove on the side wall of the placement tray 3. When the moving rod 4 undergoes lateral displacement, the gear 6 rolls along the rack 7, driving the rotating tube 5 to rotate. A fixing block 14 welded to the outer wall of the moving tube 8 has a positioning hole. The right end of the moving rod 4 penetrates the side wall of the placement tray 3 and is inserted into this positioning hole, achieving a mechanical connection between the moving rod 4 and the moving tube 8.

[0042] The top and bottom inner walls of the cultivation box 1 are respectively provided with grooves, and two connecting blocks 10 are respectively embedded in the grooves. The bottom connecting block 10 is slidably sleeved on the outer periphery of the slide rod 11 located in the bottom groove. The top connecting block 10 and the lead screw 12 located in the top groove and rotatably connected to the groove form a helical transmission pair. The right end of the lead screw is connected to the output shaft of the motor 13 through a 90-degree deflector. When the motor 13 is running, it drives the moving tube 8 to reciprocate longitudinally through the lead screw and nut mechanism. Its stroke range covers the working area of ​​all the placement trays 3.

[0043] Multiple spray pipes 9 are welded equidistantly to the outer wall of the moving pipe 8. The multiple spray pipes 9 are arranged corresponding to a single placement tray 3. Multiple atomizing nozzles are installed at the bottom of the spray pipes 9. The end of the pipe is connected to an external constant temperature water source through a connecting hose 15. During the movement of the moving pipe 8, the spray pipes 9 move accordingly to achieve uniform wetting of the seeds, and the lateral displacement of the moving rod 4 triggers the turning mechanism to work.

[0044] This application can be used in the field of rice cultivation technology, or in other fields applicable to this application.

[0045] Example 2: Reference Figure 1-5 Based on Embodiment 1, an improvement is made to a rice seed germination device, which is applied to the field of rice planting technology. The environmental control system includes: monitoring components 17 installed at different angles on both sides of the cultivation chamber 1, each of which includes a high-precision temperature and humidity sensor; a dehumidifier 19 installed at the top is connected to the inside of the chamber through a pipe, and automatically starts to dehumidify when the humidity sensor detects a value exceeding a set threshold; ceramic heating plates 18 embedded in both sides of the chamber adopt a PID control algorithm to quickly heat up to the set value in a low-temperature environment; and a drain pipe 20 installed at the bottom is equipped with a solenoid valve to periodically remove condensate.

[0046] However, as is well known to those skilled in the art, the working principle and wiring method of the 13 motor components are commonplace and are all conventional methods or common knowledge. Therefore, they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
