Description

Technical Field

[0001] This utility model belongs to the technical field of orchard frost protection equipment, specifically relating to a microparticle vibrating chamber for orchard frost protection. Background Technology

[0002] Frost is an agricultural meteorological disaster, classified into three types based on its occurrence mechanism: radiation-induced, advection-induced, and mixed-type. Based on its timing, it is divided into late frost (occurring in late spring and early summer) and early frost (occurring in late autumn). When frost occurs, the temperature drops below 0°C, causing the cell sap of newly formed tissues such as inflorescences, young fruits, and tender buds to freeze. This leads to cell wall expansion and rupture, water loss, and invasion by harmful bacteria, resulting in reduced crop yields or even total crop failure.

[0003] Traditional frost prevention methods include fumigation, air turbulence, and water injection. These methods all aim to raise the surface temperature, but in practice, their effectiveness is unsatisfactory. In recent years, a breakthrough has been achieved in the three-dimensional frost prevention engineering technology integrating "wind and fog warming + ice coating insulation + chemical cold resistance." Among these, ice coating insulation is the most crucial element. Ensuring the formation of an ice-covered layer before the inflorescences (young fruits, tender buds) are damaged by freezing is key. The concentration of particulate matter in the air is one of the necessary conditions for rapid freezing. Therefore, how to prepare the required particulate matter at a low cost is an urgent problem to be solved. Summary of the Invention

[0022] Example 1

[0023] The principle behind orchard frost prevention using fogging and ice-coating techniques is as follows: A fogging platform continuously creates a dense water mist environment. While disturbing airflow, the energy carried by the water mist raises the orchard ground temperature. More importantly, the dense water mist environment simultaneously creates the necessary conditions for freezing. If the warming effect cannot maintain the orchard temperature at 0℃, an ice layer will quickly form on the inflorescences or young fruits. As the temperature continues to drop, the ice layer will thicken. In this way, the ice layer effectively blocks the path of external low temperature conduction to the cells of the inflorescences or young fruits, thus ensuring that the temperature of the inflorescences or young fruits remains above 0℃. This prevents the water inside the cells from freezing, effectively protecting the new plant tissues and achieving the purpose of frost prevention. The presence of suitable particles in the air is a crucial means for the rapid formation of an ice layer on the inflorescences or young fruits.

[0024] To generate microparticles that meet the requirements for frost protection in wind-blown fog and for ice-resistant clothing, this utility model provides a method such as... Figures 1-2The microparticle vibrating chamber for orchard frost protection shown includes a raw material box 1, a gas mixing chamber 2 located above the raw material box 1 and connected to the raw material box 1, and a filter screen 3 located between the raw material box 1 and the gas mixing chamber 2. An air inlet pipe 4 and a mixed gas outlet pipe 5 are located above the gas mixing chamber 2. Specifically, the dimensions are 60cm × 50cm × 40cm (length × width × height). The gas mixing chamber 2 is the same as the raw material box 1 in length and width, except that its height is slightly lower. Both the raw material box 1 and the gas mixing chamber 2 are made of galvanized iron. The air inlet pipe 4 can be a common φ20 PVC pipe, approximately 5cm long. The mixed gas outlet pipe 5 is a UPVC φ32 pipe, 5cm to 10cm longer than the air inlet pipe 4, to facilitate connection with a venturi tube. This venturi tube is a common venturi tube; further details are omitted in this embodiment.

[0025] Furthermore, the raw material box 1 is provided with a raw material drawer 6. The raw material drawer 6 facilitates the addition of raw materials that generate microparticles into the raw material box 1. The horizontal plate of the raw material drawer 6 is made of ultra-thin stainless steel.

[0026] Furthermore, a filter screen fixing strip 7 is provided inside the raw material box 1 and below the filter screen 3. The filter screen fixing strip 7 is integrally set with the inner wall of the raw material box 1. Its main function is to fix the filter screen 3. Alternatively, the filter screen 3 can be fixed to the raw material box 1 by fixing wire or screws to ensure that the filter screen 3 is fixed in position and will not shake with the vibration of the entire orchard frost-proof microparticle vibration chamber.

[0027] Furthermore, the filter screen 3 is a 100-mesh filter screen, which can screen out raw material particles that meet the antifreeze requirements.

[0028] Furthermore, the intake pipe 4 is a standard φ20PPR pipe.

[0029] Furthermore, the mixed gas output pipe 5 is a φ32PPR pipe.

[0030] Furthermore, the aforementioned Venturi tube can also be replaced with a dedicated gas mixing tube for orchard frost protection and auxiliary spraying; such as Figure 3The diagram shows the connection structure between a vibrating microparticle chamber and a venturi tube for orchard frost protection. The gas mixing tube, used for orchard frost protection and auxiliary spraying, includes a compression end 8. The small end of the compression end 8 is connected to one end of a throat 9, and the other end of the throat 9 is connected to the small end of a diffuser end 10. An intake end 11 is also provided in the middle of the throat 9, and the intake end 11 is inclined towards the compression end 8. The large end of the compression end 8 is also connected to a first air duct 12, and the large end of the diffuser end 10 is also connected to a second air duct 6. The mixed gas output pipe 5 is connected to the intake end 11 of the gas mixing tube for orchard frost protection and auxiliary spraying. By connecting the intake end 11 of the gas mixing tube for orchard frost protection and auxiliary spraying to the mixed gas output pipe 5 of the vibrating microparticle chamber for orchard frost protection, the mixture of microparticles and air in the gas mixing chamber 2 can be sucked away.

[0031] Furthermore, the raw materials that generate microparticles placed in the raw material drawer 6 refer to small particles such as corn starch.

[0032] The working process of the gas mixing pipe used for orchard frost prevention and auxiliary spraying is as follows: First, open the raw material drawer 6 of the orchard frost prevention particle vibration chamber to add raw materials. Then, place the entire orchard frost prevention particle vibration chamber on an agricultural tricycle. Connect the mixed gas output pipe 5 to the intake end 11 of the gas mixing pipe used for orchard frost prevention and auxiliary spraying. The first air pipe 12 and the second air pipe 13 of the gas mixing pipe used for orchard frost prevention and auxiliary spraying are respectively connected to the blower output pipe and the gas supply pipe. Through the continuous vibration of the tricycle, the raw materials in the raw material box 1 are continuously vibrated, generating particles. After being filtered by the filter screen 3, the particles enter the gas mixing chamber 2 and mix with the air entering through the air inlet pipe 4. They are then sucked into the mixed gas output pipe 5. In this way, the particle-air mixture generated by the orchard frost prevention particle vibration chamber is sent into the gas supply pipe. The gas supply pipe system sprays the orchard, which can quickly transport the particles generated by the orchard frost prevention particle vibration chamber to the orchard, thereby forming a wind and fog environment that meets the needs of frost prevention for use.

[0033] In summary, this microparticle vibrating chamber specifically designed for orchard frost protection creates the necessary conditions for water mist to freeze. It features a simple structure, easy operation, and convenient use. No special drive device is required; simply place the raw materials in the material drawer and position the chamber on a vibrating flat iron plate on an existing tricycle to continuously generate microparticles.

[0034] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
