Description

Technical Field

[0001] This utility model relates to the field of agricultural breeding and processing equipment technology, and in particular to a constant temperature ultrasonic germination device for oats. Background Technology

[0002] As a grain with extremely high nutritional value, oats have strict requirements for environmental conditions during the germination process. In laboratory research or large-scale breeding and processing, it is usually necessary to use a special germination device to provide suitable conditions such as moisture and temperature. Most existing germination devices use a single water pump spray system, which mainly focuses on the timed replenishment of culture medium.

[0003] However, in actual breeding experiments or production, in order to improve the germination rate or conduct specific resistance experiments, it is often necessary to frequently switch between water spraying and culture medium (or chemical solution) supply. Existing single-pipe germination devices are inadequate in the face of such needs. Users usually need to manually disassemble the water inlet pipe and move it from the water tank to the liquid addition tank, or directly pour the culture medium or chemical solution into the large water tank for mixing. The former is cumbersome and can easily cause the pipe joints to loosen and leak, while the latter will cause the entire large water tank to be contaminated, making subsequent cleaning extremely difficult, and it is easy for the precision nozzles to be blocked by the sediment in the chemical solution, which seriously affects the service life of the equipment and the continuity of the experiment. In addition, many devices have relatively simple functions and lack integrated constant temperature control and ultrasonic assistance, resulting in long seed germination cycles and low uniformity.

[0004] Therefore, this utility model proposes a constant temperature ultrasonic germination device for oats to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the oat germination device, such as cumbersome operation, easy blockage and contamination of pipelines, and low germination efficiency due to lack of integrated environmental auxiliary control during the switching of water source and culture medium, this utility model aims to provide an oat isothermal ultrasonic germination device with improved structure that can effectively solve the above problems.

[0006] This utility model provides a constant temperature ultrasonic germination device for oats. The main structure of the device includes a support mechanism, which encompasses a box-shaped body, a water pump fixedly installed on the outer wall of the body as a power source, and a water storage tank fixedly installed on one side of the body for storing clean water. The output end of the water pump is connected to a first connecting pipe extending into the body and equipped with a nozzle. The device also includes a flow switching mechanism for switching the flow path and a liquid addition mechanism for independently supplying the medicinal solution.

[0007] The flow exchange mechanism includes a second connecting pipe connected to the input end of the water pump. The pipe wall of the second connecting pipe is connected to a water pumping pipe that extends into the water tank and a vertically upward downflow pipe. The core component inside the second connecting pipe is a rotatable three-way ball. The three-way ball has a specific T-shaped flow channel inside, which can be switched between different angles by the drive of an external handle, thereby selectively guiding the clear water channel or the culture medium channel. The liquid addition mechanism includes a tank whose bottom end is connected to the downflow pipe, and the interior of the machine body also integrates a heating component and an ultrasonic generating component.

[0008] Furthermore, the flow exchange mechanism is located on one side of the support mechanism, serving as a hub connecting the water tank, the liquid filling mechanism, and the water pump. The three-way ball is rotatably installed inside the second connecting pipe, changing the fluid direction through mechanical rotation. The tank of the liquid filling mechanism is directly situated above the downflow pipe, utilizing gravity to assist in liquid supply. The heating component and the ultrasonic generating component are built into the body or the water tank, together forming a comprehensive germination system integrating fluid control and environmental regulation.

[0009] Preferably, the external drive structure of the three-way ball is designed such that a rotating shaft is fixedly connected to the outer wall of the three-way ball. The rotating shaft extends to the outside through a shaft hole opened on the outer wall of the second connecting pipe, and a handle for easy hand operation is fixedly connected to the end. The T-shaped flow channel inside the three-way ball is composed of mutually perpendicular through holes and perforations. By rotating the handle, the orientation of the through holes and perforations can be precisely controlled, thereby achieving the blocking and opening of the pumping pipe or the downflow pipe.

[0010] Preferably, in order to ensure the cleanliness and safety of the liquid, the liquid dispensing mechanism also includes a top cover that fits onto the top of the tank. The outer wall of the top cover is fixedly provided with several hooks. Correspondingly, the outer wall of the tank is equipped with elastic buckles. Through the snap-fit ​​between the elastic buckles and the hooks, the top cover can be quickly locked and sealed to prevent the liquid from evaporating or external dust from falling in.

[0011] Preferably, in order to further improve the ease of installation and sealing of the top cover, a positioning groove is provided on the upper surface of the tank body, and a positioning post is provided on the lower surface of the top cover. Precise alignment is achieved by inserting the positioning post into the positioning groove. At the same time, a transparent glass window is embedded in the center of the top cover, so that the user can intuitively monitor the changes in the liquid level in the tank without opening the cover, thus avoiding the pump running dry.

[0012] Preferably, in order to prevent undissolved particles in the culture medium or drug solution from clogging the nozzle, a filter screen is slidably connected to the inner wall of the tank. The filter screen is located above the outlet pipe interface, and all outflowing culture medium or drug solution must be filtered through the filter screen. The sliding design makes it easy to remove and clean.

[0013] Preferably, in order to enhance the stability of the external structure, the outer wall of the second connecting pipe is fixedly connected to the outer wall of the body through a connecting block, and the downflow pipe is vertically fixed to the top of the second connecting pipe to form a stable support structure.

[0014] Preferably, in order to make reasonable use of the internal space and meet the germination requirements, a partition is fixedly installed horizontally inside the machine body. The partition is located directly below the nozzle and is used to stably place the tray carrying the seeds to ensure uniform spray coverage.

[0015] Preferably, in order to achieve intelligent control, the outer wall of the machine body is provided with a control panel, which is electrically connected to the water pump, the heating component and the ultrasonic generating component, respectively, for centralized control of the working status of each component.

[0016] Preferably, the heating component is an electric heating rod fixed inside the water tank, which, together with the heat insulation layer laid on the inner wall of the machine, can effectively maintain the constant temperature environment required for germination. The ultrasonic generating component is an ultrasonic transducer fixedly installed on the bottom wall of the machine, which assists seed germination by releasing high-frequency oscillation waves.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting up a flow-changing mechanism, uses a rotary handle to drive an internal three-way ball valve to switch the flow channel at different angles, thereby selectively connecting the water tank or liquid tank and the water pump. This solves the problem of cumbersome operation and frequent disassembly of pipelines or cleaning of containers when switching between clean water spraying and culture medium supply in the prior art. It achieves the technical effect of using a single water pump system to realize rapid switching between two water sources, convenient operation and avoidance of cross-contamination.

[0018] 2. This utility model solves the problems in the prior art where drugs or culture media are easily clogged by impurities in the precision nozzle and it is difficult to observe the remaining liquid level in real time by setting a sliding filter screen and a top visual glass window in the liquid adding mechanism. It achieves the technical effect of effectively intercepting undissolved particles to protect the spraying system, extend the service life of the equipment, and at the same time facilitate users to monitor the liquid level changes in real time and replenish the liquid in a timely manner.

[0019] 3. This utility model solves the problems of low germination rate or long growth cycle caused by the single function and lack of targeted environmental control of traditional germination devices by integrating heating components and ultrasonic generating components inside the machine body. It achieves the technical effect of maintaining a constant temperature environment suitable for seed growth and using ultrasonic vibration to stimulate seed cell activity and accelerate water absorption, thereby improving the germination rate of oat seeds and shortening the germination cycle.

[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] Please refer to Figures 1 to 6 This utility model provides a constant temperature ultrasonic germination device for oats, which aims to solve the structural defects of existing germination devices, such as cumbersome operation of switching between water spraying and culture medium supply, easy blockage of pipelines due to impurities in the solution, and lack of integrated constant temperature ultrasonic assisted germination environment.

[0024] like Figure 1 and Figure 2As shown, the main structure of the oat constant temperature ultrasonic germination device includes a support mechanism 1 as a basic bearing platform, and a flow exchange mechanism 2 and a liquid supply mechanism 3 that rely on the support mechanism 1 for flow path control and liquid supply. The support mechanism 1 includes a box-shaped body 101. A water tank 105 for storing basic water source is fixedly connected to one outer wall of the body 101. A water pump 104 is fixedly installed on the outer wall of the body 101 next to the water tank 105 by bolts. The water pump 104 serves as the fluid power source of the system, and its output end is sealed and connected to a first connecting pipe 106, which is L-shaped. Alternatively, a curved tube-like structure can penetrate the side wall of the body 101 and extend to the top of the internal cavity of the body 101. The first connecting pipe 106 is located inside the body 101, and one end is fixedly connected to a nozzle 107. The nozzle of the nozzle 107 is set downward, which can atomize the liquid pumped by the water pump 104 and spray it evenly into the interior of the body 101. The internal space of the body 101 is divided by a horizontally fixed partition 103. The partition 103 is located directly below the nozzle 107, and its upper surface is used to stably place the tray for holding seeds, thereby ensuring that the water mist sprayed by the nozzle 107 can fully cover the seeds in the tray.

[0025] To meet the specific environmental requirements for oat germination, the inner wall of the machine body 101 is fully covered with an insulation layer, which can effectively reduce heat loss. The internal system of the machine body 101 integrates environmental regulation functions, specifically including a fixedly installed heating component and an ultrasonic generator component. The heating component uses an electric heating rod, which is sealed and fixedly installed at the bottom of the water tank 105. It can directly heat and control the water source in the water tank 105, so that the sprayed liquid itself has a suitable temperature.

[0026] An electric heating rod can also be installed in the water collection tank at the bottom of the body 101 to maintain the ambient temperature. The ultrasonic generating component uses an industrial-grade or laboratory-grade ultrasonic transducer, which is fixedly installed on the inner bottom wall of the body 101. The high-frequency vibration waves generated during operation can be transmitted to the seed surface, which can accelerate water absorption and promote enzyme activity. A control panel 102 is fixedly installed on the front outer wall surface of the body 101. The control panel 102 integrates a microprocessor and a relay module, and is electrically connected to the water pump 104, the heating component and the ultrasonic generating component through wires. Users can achieve integrated and precise control of spraying time, heating temperature and ultrasonic frequency by operating the control panel 102.

[0027] The converter mechanism 2 includes a second connecting pipe 203, which serves as a fluid transfer hub. One end of the second connecting pipe 203 is sealed and connected to the inlet of the water pump 104 via a flange or threaded joint. Interfaces are respectively provided on the wall of the second connecting pipe 203, connecting to a suction pipe 206 and a downflow pipe 205. The end of the suction pipe 206 away from the second connecting pipe 203 extends in a curved shape to the bottom of the water tank 105, used to draw clean water from the water tank 105. The downflow pipe 205 is vertically erected and fixed to the top of the outer wall of the second connecting pipe 203, used to receive the liquid supply mechanism above. The liquid flowing down has a core control component, a three-way ball 202, rotatably mounted inside the second connecting pipe 203. The outer wall of the three-way ball 202 is tightly fitted to the inner wall of the second connecting pipe 203 through a sealing gasket, which ensures both the flexibility of rotation and the sealing of the flow path. A rotating shaft is fixedly connected to the outer wall of the three-way ball 202. A shaft hole 204 is opened at a corresponding position on the outer wall of the second connecting pipe 203 for the rotating shaft to pass through. The rotating shaft extends to the outside through the shaft hole 204 and is fixedly connected to a handle 201 for easy hand operation at its end. The outer surface of the handle 201 is provided with anti-slip texture.

[0028] The three-way ball 202 has a specific T-shaped flow channel inside. This flow channel structure includes horizontal through-holes running through the left and right sides of the ball and perforations perpendicular to these through-holes and extending to the surface of the ball. By rotating the handle 201, the three-way ball 202 can be switched 90 degrees between a first position and a second position. In the first position, i.e., the water replenishment spray mode, the through-holes inside the three-way ball 202 are horizontal, so that the water pumping pipe 206 is connected to the input end of the water pump 104. At the same time, the solid part of the outer wall of the three-way ball 202 completely blocks the upper downflow pipe 205 interface. At this time, the water pump 104 only draws water from the water tank 1. The clean water in position 05 is sprayed. In the second position, i.e., the dosing mode, the handle 201 is rotated 90 degrees, which changes the flow channel structure in the three-way ball 202. The originally horizontal through hole becomes vertical, and the through hole is connected to the downflow pipe 205, thereby connecting the downflow pipe 205 to the water pump 104. At the same time, the interface of the water pump 206 is blocked by the outer wall of the rotated three-way ball 202, and the water pump 104 starts to draw liquid from the liquid dosing mechanism 3. This mechanical switching structure based on the rotary ball valve avoids complex solenoid valve control and greatly improves the reliability and durability of the equipment in humid environments.

[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, to achieve safe storage and convenient supply of drugs or culture media, the liquid dispensing mechanism 3 includes a cylindrical hollow tank 303. The bottom center of the tank 303 has a liquid outlet that is sealed and connected to the top of the downflow pipe 205. The top opening of the tank 303 has a matching top cover 301. To ensure the sealing and stability of the tank 303 during operation, hooks 305 are evenly distributed and fixedly connected to the outer wall of the top cover 301. Correspondingly, an elastic buckle 304 is fixedly installed at the upper end of the outer wall of the tank 303. The elastic buckle 304 includes a spring and a locking assembly. By pressing the elastic buckle 304 downward, it is locked onto the hooks 305. The tension of the spring is used to tightly press the top cover 301 onto the tank 303 to prevent the liquid from evaporating or being contaminated by the outside.

[0030] As another preferred embodiment, in order to facilitate quick alignment when installing the top cover 301, a positioning groove 307 is provided at the edge of the upper surface of the tank body 303, and a positioning post protruding from the corresponding position on the lower surface of the top cover 301 is provided, which is adapted to the shape of the positioning groove 307. When fastening the top cover 301, the positioning post can be inserted into the positioning groove 307 to achieve precise positioning and prevent misalignment of the cover from causing poor sealing. In addition, in order to allow users to observe the changes in the liquid level in the tank in real time without opening the top cover 301, a hole is opened in the center of the top cover 301 and a transparent glass window 302 is embedded therein. The glass window 302 is bonded to the top cover 301 with sealant, which ensures visibility and maintains the overall sealing performance.

[0031] As a further preferred embodiment, in order to prevent incompletely dissolved drug particles or external impurities from entering the pipeline system and clogging the precision nozzle 107, a filter screen 306 is provided inside the tank 303. The outer diameter of the filter screen 306 matches the inner diameter of the tank 303, and the edge of the filter screen 306 is slidably connected to the inner wall of the tank 303. The filter screen 306 is located above the outlet of the downpipe 205, so that all liquid flowing down the downpipe 205 must pass through the filter holes of the filter screen 306. This slidable connection design also allows users to easily remove the filter screen 306 for cleaning or replacement.

[0032] As another preferred embodiment, in order to enhance the stability of the overall structure and avoid excessive stress on the pipeline due to the weight of the external liquid filling mechanism 3, the outer wall of the second connecting pipe 203 is fixedly connected to the side wall of the body 101 through the connecting block 308. The connecting block 308 plays an important supporting and reinforcing role, ensuring that the position of the exchange mechanism 2 and the liquid filling mechanism 3 is stable during long-term use. In order to facilitate intelligent monitoring of the germination process, the control panel 102 can not only control the switching of each electrical component, but also integrate a timer module to set the intermittent working cycle of the water pump 104 and set the constant temperature threshold of the heating component, thereby realizing fully automated germination management.

[0033] The working principle of this oat constant temperature ultrasonic germination device is as follows: When routine water replenishment is required, the user first confirms that the handle 201 is in the normal position. At this time, the non-through hole in the three-way ball 202 faces downward, and the ball wall blocks the downward flow pipe 205 channel of the upper liquid filling mechanism 3. The through hole is horizontal, so that the water pump 206 is connected to the input end of the water pump 104. Then, the water pump 104 is started through the control panel 102. The water pump 104 generates negative pressure to draw clean water from the water tank 105 through the water pump 206, and then enters the pump body through the second connecting pipe 203. Finally, it is pressurized and delivered to the nozzle 107 through the first connecting pipe 106, and sprayed evenly in the seed tray on the partition 103 in the form of mist. During this process, the control panel 102 activates the heating component in the water tank 105 in a timely manner to maintain the water temperature according to the preset program or sensor feedback, and intermittently activates the ultrasonic generator component at the bottom of the machine body 101 to promote the activity of seed cells by using ultrasonic vibration.

[0034] When seeds need to be sprayed with nutrient solution or treated with chemicals, the user rotates the handle 201 90 degrees clockwise, causing the internal three-way ball 202 to rotate. At this time, the through hole of the three-way ball 202 becomes vertical, connecting the downflow pipe 205 and the water pump 104, while the channel originally connected to the water pump 206 is blocked by the ball wall. The user pours the prepared nutrient solution into the tank 303. After the liquid passes through the filter screen 306 to remove impurities, it enters the downflow pipe 205. The water pump 104 is started again, and the water pump 104 directly draws the nutrient solution from the tank 303 and sprays it onto the seed surface through the nozzle 107. Through this simple mechanical switching, the independent supply of clean water and chemical solution is achieved, effectively avoiding the problem of chemical solution residue contaminating the water tank 105 or clogging the pipes. At the same time, the visible glass window 302 allows the user to monitor the remaining amount of chemical solution in real time and replenish it in time.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
