Description

A heat preservation device for earthworm farming in low-temperature environments Technical Field

[0001] This utility model belongs to the field of earthworm farming technology, specifically relating to a heat preservation device for earthworm farming in low-temperature environments. Background Technology

[0002] Earthworm farming has multiple benefits in agriculture, economy, and ecology. Earthworm castings are a high-quality organic fertilizer, rich in humus, nitrogen, phosphorus, potassium, and other nutrients, which can improve soil fertility, promote crop growth and increase yield. Earthworm farming is of great significance in improving soil, increasing agricultural output, increasing economic income and protecting the environment, and is an ecological agricultural model with broad prospects.

[0003] Currently, when raising earthworms in low-temperature environments, soil mixed with earthworms is placed inside a container to reduce the rate of soil temperature loss. However, this method, which uses passive insulation to retain heat, is greatly affected by fluctuations in the external environment temperature. It is difficult to maintain a stable soil temperature inside the device when the temperature drops significantly, which can easily lead to a decrease in the survival rate of earthworms due to low temperatures, making it quite inconvenient. Summary of the Invention

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a heat preservation device for earthworm farming in low-temperature environments. This addresses the issue mentioned in the background art, where earthworm-infused soil is placed inside a box to reduce the rate of soil temperature loss during earthworm farming. However, this passive heat preservation method is highly susceptible to fluctuations in external ambient temperature, making it difficult to maintain stable soil temperature even with significant temperature drops. This can easily lead to a decrease in earthworm survival rate due to low temperatures, causing considerable inconvenience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat preservation device for earthworm farming in low-temperature environments, comprising a box mechanism for holding soil mixed with earthworms and maintaining temperature stability at low temperatures by providing a heat source. The box mechanism includes a first screw threadedly connected to one side of an outer box and symmetrically arranged, and a heat preservation plate fixedly connected to the inner side of the outer box. A sliding arm is movably connected to the outer side of the first screw through a limiting hole. A bottom frame is fixedly connected to one side of the bottom end of the sliding arm. A first heating tube is fixedly connected to the top of the bottom frame. A plurality of second heating tubes are symmetrically arranged on the top of the first heating tube. A heat-conducting plate and a sealing plate are slidably connected to the outer side of the second heating tubes. A sealing plate is fixedly connected to the top of the heat-conducting plate. The bottom frame is threadedly connected to one side of the sealing plate through a plurality of symmetrically arranged second screws. By releasing stable heat to the soil through the first and second heating tubes, the device can stably maintain the temperature required for earthworm survival in low-temperature environments with large temperature fluctuations.

[0006] Preferably, the bottom of the outer casing is fixedly connected with foot pads, and several foot pads are symmetrically arranged, all of which are cylindrical structures.

[0007] Preferably, the sliding arms are fixedly connected to each other by a truss, and the inner side of each sliding arm is movably connected to a first screw through a limiting hole.

[0008] Preferably, a washer is movably connected to the outer side of one end of the first screw, and the washer is located on one side of the sliding arm.

[0009] Preferably, the limiting hole has a U-shaped structure, and a first screw is movably connected to the inner side of the limiting hole.

[0010] Preferably, a sealing strip is fixedly connected to one side of the bottom of the sealing plate, and an outer casing is slidably connected to the outside of the sealing strip.

[0011] Preferably, a cavity sleeve is fixedly connected to the top of the sealing plate, and several cavity sleeves are symmetrically arranged. A second heating tube is slidably connected to the inner side of the cavity sleeve.

[0012] Preferably, the first heating tube has a spring-shaped structure, and a bottom frame is fixedly connected to the bottom of the first heating tube.

[0013] Compared with the prior art, this utility model provides a heat preservation device for earthworm farming in low-temperature environments, which has the following beneficial effects:

[0014] 1. This utility model features a first heating tube with a base frame fixedly connected to its bottom. A sliding arm is fixedly connected to the outside of the base frame, and a first screw is movably connected to the inside of the sliding arm via a U-shaped limiting hole. An outer casing is threaded to the outside of the first screw. Several second heating tubes are symmetrically arranged on the top of the first heating tube, and a heat-conducting plate is slidably connected to the outside of each second heating tube. A sealing plate is fixedly connected to the top of the heat-conducting plate, and the base frame is threaded to one side of the sealing plate via symmetrically arranged second screws. Based on the volume of soil mixed with earthworms in earthworm farming, rotating counterclockwise and loosening each first screw, along with the U-shaped limiting hole, raises and lowers the base frame at the bottom of the sliding arm to the desired height, thus adjusting the internal capacity of the outer casing. Then, the first screw is rotated clockwise to fix the height position. The soil mixed with earthworms is spread evenly on the top of the inner sealing plate of the outer box. Then, the first heating tube is turned on to maintain the temperature conditions at the bottom of the soil. The temperature is then directed to the second heating tube through the first heating tube. The second heating tube keeps the soil warm at different heights. By providing an active heat source for the device, the passive heat preservation method can effectively reduce the temperature stagnation caused by the passive heat preservation method. This reduces the impact of the device on the external temperature fluctuations and makes it difficult to maintain the stability of the soil temperature in the device when the temperature drops significantly. This ensures the survival rate of earthworm farming in low-temperature environments.

With the help of the U-shaped limiting hole 104, the bottom frame 106 at the bottom of the sliding arm 105 is raised or lowered to the required height to adjust the internal capacity of the outer box 101. Then, the first screws 103 are rotated clockwise to fix the height position. The soil mixed with earthworms is spread evenly on the top of the inner sealing plate 111 of the outer box 101.

Using the U-shaped limiting hole 104, raise and lower the bottom frame 106 of the sliding arm 105 to the required height, adjusting the internal capacity of the outer box 101. Then, rotate the first screw 103 clockwise to fix the height position, spreading the soil mixed with earthworms evenly onto the top of the inner sealing plate 111 of the outer box 101. Then, turn on the first heating tube 107 to maintain the temperature at the bottom of the soil. The temperature is then directed through the first heating tube 107 to the second heating tube 108, which insulates different heights within the soil. By providing an active heat source for the device, the passive heat preservation method effectively reduces the impact of temperature stagnation caused by external environmental temperature fluctuations, making it difficult to maintain the stability of the soil temperature under significant temperature drops.
