Description

Technical Field

[0001] This utility model relates to the field of tomato seedling technology, specifically a tomato seedling heat preservation device. Background Technology

[0002] Tomato seedling cultivation uses lightweight, soilless substrates such as peat moss and vermiculite as the seedling substrate, and employs mechanized precision sowing, with one seed per hole. Its outstanding advantages are labor-saving, energy-saving, and high efficiency; the root ball is not easily broken, seedlings recover quickly, and the survival rate is high. It is suitable for long-distance transportation and mechanized transplanting, which is conducive to standardized and scientific management, improves the quality of commercial seedlings, promotes the development of superior varieties, and reduces the harm caused by the proliferation of counterfeit and inferior seeds.

[0003] Currently, tomato seedling cultivation generally uses mulch film to maintain warmth. Professional growers often rely on greenhouses for centralized seedling cultivation, which facilitates temperature control. However, with the acceleration of urbanization and the improvement of living standards, more and more families are starting to use planting boxes for tomato seedling cultivation. But the current family seedling cultivation methods mostly just cover the planting box with a layer of plastic wrap to insulate against heat conduction, making it difficult to achieve precise temperature control. This results in unstable seedling temperatures, which in turn affects the germination rate and seedling cultivation effect of tomatoes. Utility Model Content

[0004] The purpose of this invention is to provide a tomato seedling heat preservation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A tomato seedling insulation device includes a planting box, and further includes: A clamping assembly is disposed at the upper end of the planting box, and the clamping assembly includes a mounting plate; A heating assembly is located above the mounting plate. The heating assembly includes a heating chamber, inside which a heating rod is fixedly installed. Connecting pipes are symmetrically fixedly connected to the lower surface of the heating chamber. An intake fan and an exhaust fan are fixedly connected to the two connecting pipes respectively. The reinforcement components are located below the mounting plate.

[0006] Furthermore, multiple sliding sleeves are symmetrically fixedly installed on the upper surface of the mounting plate, and sliding rods are slidably connected inside the sliding sleeves. Two sliding rods at corresponding positions have clamps fixedly connected to one end, and springs are movably sleeved on the outside of the sliding rods. The two ends of the springs are fixedly connected to the sliding sleeves and clamps, respectively.

[0007] Furthermore, a temperature sensor is fixedly installed on the upper surface of the heating chamber, and an air inlet plug is movably embedded in the surface of one end of the heating chamber.

[0008] Furthermore, the reinforcement components include: The support plate is located below the mounting plate; Multiple tapered inserts are fixedly installed at equal intervals on the upper surface of the abutment plate.

[0009] Preferably, a rubber sleeve is fixedly installed on the outer surface of the tapered insert, and multiple slots are equidistantly opened on the lower surface of the mounting plate, with the rubber sleeve engaging with the slots at the corresponding positions.

[0010] Preferably, the surface of the support plate is symmetrically provided with through holes, and the upper part of the planting box, located between the mounting plate and the support plate, is covered with plastic wrap.

[0011] Preferably, the upper surface of the mounting plate is symmetrically and fixedly embedded with connecting rings that can be movably inserted into the connecting pipe, and the lower surface of the mounting plate is symmetrically and fixedly mounted with annular cutters that can be movably inserted into through holes at corresponding positions.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By moving two clamps inward to hold the side wall of the planting box, the mounting plate is supported above the planting box. The temperature sensor detects the temperature inside the heating chamber. When the temperature is lower than the set value, the heating rod works to heat the air flowing through the heating chamber, raising the temperature inside the planting box. When the temperature is higher than the set value, the user can manually open the air inlet cover by reading the temperature value on the temperature sensor, introducing low-temperature outside air into the heating chamber. This also facilitates the injection of oxygen into the planting box, maintaining the oxygen content inside. Thus, the air temperature is controlled during airflow, regulating the temperature inside the planting box. This makes the insulation device suitable for home seedling cultivation, improving the germination rate and seedling effect. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1-5 In this embodiment of the present invention, a tomato seedling heat preservation device includes a planting box 1 and a clamping component 2, which is disposed on the upper end of the planting box 1. The clamping component 2 includes a mounting plate 201. A heating component 3 is disposed above the mounting plate 201. The heating component 3 includes a heating chamber 301. A heating rod 302 is fixedly installed inside the heating chamber 301. A connecting pipe 303 is symmetrically fixedly connected to the lower surface of the heating chamber 301. An air intake fan 304 and an exhaust fan 305 are fixedly connected inside the two connecting pipes 303 respectively. A reinforcing component 4 is disposed below the mounting plate 201. A plastic wrap 101 is covered on the upper end of the planting box 1 between the mounting plate 201 and the backing plate 401.

[0017] Specifically, the plastic wrap 101 is placed over the planting box 1 to seal the top of the planting box 1. The heating component 3 is fixed to the top of the planting box 1 by the clamping component 2, so that the heat of the heating component 3 can enter the interior of the planting box 1. The mounting plate 201 and the plastic wrap 101 are fixed by the reinforcing component 4 to prevent heat from being directly discharged from the connection between the plastic wrap 101 and the mounting plate 201.

[0018] Example 1 like Figure 1-3 As shown, in this embodiment, multiple sliding sleeves 202 are symmetrically fixedly installed on the upper surface of the mounting plate 201. Sliding rods 203 are slidably connected inside the sliding sleeves 202. One end of two sliding rods 203 at corresponding positions is fixedly connected to a clamping plate 204. A spring 205 is movably sleeved on the outside of the sliding rod 203. The two ends of the spring 205 are fixedly connected to the sliding sleeve 202 and the clamping plate 204, respectively.

[0019] In this embodiment, the spring 205 always pulls the clamping plate 204 with a force that moves it toward the mounting plate 201, causing the two clamping plates 204 to move inward to facilitate clamping the side wall of the planting box 1. At the same time, the slide rod 203 rests against the upper edge of the planting box 1, supporting the mounting plate 201 above the planting box 1.

[0020] like Figure 2 As shown, in this embodiment, a temperature sensor 306 is fixedly installed on the upper surface of the heating chamber 301, and an air inlet plug 209 is movably embedded in one end surface of the heating chamber 301.

[0021] In practice, when the heating rod 302 is not working, the intake fan 304 and exhaust fan 305 operate, causing air to circulate inside the planting box 1. As the air flows through the heating chamber 301, the temperature sensor 306 senses the temperature inside the heating chamber 301. When the temperature is lower than the set value, the heating rod 302 operates to heat the air flowing through the heating chamber 301, increasing the temperature inside the planting box 1. When the temperature is higher than the set value, the person can manually open the air intake plug 209 by reading the temperature value on the temperature sensor 306, introducing low-temperature outside air into the heating chamber 301. This also facilitates the injection of oxygen into the planting box 1, maintaining the oxygen content inside the planting box 1. Thus, the air temperature is controlled during the airflow process, regulating the temperature inside the planting box 1. This makes the insulation device easy to use in home seedling cultivation, improving the germination rate and seedling effect of home seedling cultivation.

[0022] Example 2 Based on Embodiment 1, in order to solve the problem that hot air is easily discharged directly from the connection point when hot air passes through the mounting plate 201 due to the soft material of the plastic wrap 101.

[0023] like Figure 3-5 As shown, in this embodiment, the reinforcement component 4 includes: a backing plate 401 movably disposed below the mounting plate 201, and multiple tapered inserts 403 fixedly installed at equal intervals on the upper surface of the backing plate 401; a rubber sleeve 404 is fixedly installed on the outer surface of the tapered inserts 403, and multiple slots 208 are equidistantly opened on the lower surface of the mounting plate 201, and the rubber sleeves 404 are movably engaged with the slots 208 at corresponding positions.

[0024] In practice, when the plastic wrap 101 covers half of the plastic wrap 101, the abutment 401 is installed from below the plastic wrap 101, so that the tapered insert 403 passes through the plastic wrap and connects with the slot 208, fixing the abutment 401, improving the sealing between the plastic wrap 101 and the mounting plate 201, and reducing the risk of heat being directly discharged from the connection.

[0025] like Figure 4 and Figure 5As shown, in this embodiment, through holes 402 are symmetrically opened on one side surface of the abutment plate 401; a connecting ring 206 that is movably inserted into the connecting pipe 303 is symmetrically fixedly installed on the upper surface of the mounting plate 201; an annular cutter 207 is symmetrically fixedly installed on the lower surface of the mounting plate 201, and the annular cutter 207 is movably inserted into the through hole 402 at the corresponding position.

[0026] In practice, when the support plate 401 is installed, the annular cutter 207 is inserted into the through hole 402 to make a ring cut on the plastic wrap 101. The cut plastic wrap 101 is then removed to make the heating chamber 301 connected to the planting box 1.

[0027] In this utility model, to facilitate operator control, a PLC controller can be set up. The temperature sensor 306, heating rod 302, intake fan 304 and exhaust fan 305 are all electrically connected to the PLC controller. The signal from the temperature sensor 306 is transmitted through the PLC. After processing, the PLC causes the corresponding actuators to execute corresponding control commands according to the set control logic. The PLC controller is existing technology and will not be described in detail here.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
