Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of meteorological frost and freezing damage prevention and disaster reduction, and particularly relates to an orchard frost-proof smoke pile. Background Art
[0002] Frost is the most important low temperature disaster faced by my country's agricultural production. Agricultural meteorological disasters, especially low temperature frost, are becoming increasingly serious, resulting in a decline in the yield and quality of crops, vegetables, fruits, and other farm products, especially a huge impact on agricultural cash crops, causing huge economic losses to growers. At present, in terms of measures to prevent frost disasters, in the use of traditional smoke generation methods, the improved processes and equipment usually have the defects of too large (or too small) combustion, inconvenient fuel acquisition, high cost, and unclear effect.
[0003] In terms of fruit tree anti-frost heating and smoking devices, among the disclosed devices, the appearance and ventilation structure are considered more, and the fuel layer structure is improved less. For example, the Chinese utility model patent with the announcement number CN 218456896 U discloses a "mobile fruit tree anti-frost heating and smoking stove", and its structure improves the movable appearance and ventilation outer structure; the Chinese utility model patent with the announcement number CN206890576 U discloses a "disassembled stove for late frost prevention". The device highlights the detachable feature and reduces the volume, but uses traditional honeycomb coal fuel, without the "covering" effect of smoke, and in principle does not prevent geothermal radiation. The Chinese patent with the announcement number CN 103688809 B discloses a "plant anti-frost method and system". The device uses a geothermal source pump to heat the soil and increase the ground temperature to achieve the purpose of frost prevention. The project has a specific geographical nature and is not suitable for widespread use by ordinary growers. The Chinese utility model patent with the announcement number CN 210746395 U discloses "an orchard frost protection auxiliary heating and ignition device". The device is large in size and suitable for large-scale centralized frost protection, but it does not take into account the needs of small-scale farmers. Summary of the invention
[0004] The utility model aims to solve the problems existing in the existing frost protection heating devices and to provide an orchard frost protection smoke pile which has the advantages of simple structure, easy implementation, low cost and wide applicability.
[0005] In order to solve the above problems, the technical solution adopted by the utility model is as follows: an orchard frost-proof smoke pile, including a central ventilation hole, a top covering layer, an upper combustion layer, a middle combustion layer, a bottom combustion layer, a bottom cross ventilation hole, and an outer shell. The top smoke outlet is located on both sides of the central ventilation hole on the upper combustion layer, and is symmetrical to each other; the central ventilation hole is cylindrical and vertical. The cross ventilation hole located in the bottom combustion layer has four cylindrical openings. The central ventilation hole vertically penetrates the upper, middle and bottom three combustion layers; the combustion materials of the three combustion layers are: the bottom layer is composed of soft and easy-to-ignite straw, the middle layer is made of hard wood that is resistant to burning and has a high calorific value, and the top layer is made of dense sawdust that is easy to continue the fire. The top is a semi-sealed conical covering layer.
[0006] The bottom combustion layer is a soft and ignitable material (straw), which is ignited through the cross ventilation holes around it to play an ignition role. This layer burns first and gradually ignites the middle and upper combustion layers.
[0007] The middle combustion layer is made of hard wood (pruned branches from an orchard), which gradually burns from the center to the surrounding areas. After being ignited, the heat generated is the largest and sufficient heat is maintained.
[0008] The upper combustion layer is a dense sawdust material that is easy to ignite (made from crushed orchard branches). It starts to burn gradually from the center to the surrounding areas, gradually collapses during burning, and plays a "covering" role for the lower combustion layer to prevent it from burning too quickly.
[0009] The top covering layer is a semi-sealed conical structure, made of non-combustible (earth) material, with a closed top to prevent the airflow from rising and prevent too fast combustion. Smoke outlets are arranged around to increase the airflow length, reduce the airflow temperature, and discharge smoke.
[0010] The shell is made of ordinary iron material and has no holes at the bottom, so as to prevent the internal burning material from being placed for a long time and moisture from entering the burning layer from the bottom, thereby affecting the anti-frost effect.
[0011] The beneficial effects of the utility model are:
[0012] The materials for the device are collected from nearby sources. The materials for the upper, middle and lower combustion layers are all residual materials from farmers and orchards, which are convenient for ordinary farmers to collect and make.
[0013] The production process of the three combustion layers, upper, middle and bottom, is simple and can be produced by pressing with a preset mold, which is conducive to farmers' self-production and has a very low cost;
[0014] This device is designed to prevent violent combustion. While burning, it releases smoke to the maximum extent, helping to prevent frost. It is safe to use and has long-lasting smoke, which is suitable for outdoor conditions for fruit farmers. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1It is a structural schematic diagram of the device of the utility model.
[0016] Figure 1 Middle: 1. Central ventilation hole, 2. Top covering layer, 3. Upper combustion layer, 4. Middle combustion layer, 5. Bottom combustion layer, 6. Cross ventilation hole, 7. Outer shell, 8. Top smoke outlet. DETAILED DESCRIPTION
[0017] The specific implementation methods of the technical solution of the utility model are further described below in conjunction with the accompanying drawings.
[0018] According to Figure 1 As shown, prepare an iron shell 7 with a height and diameter of 60CM and an upper opening, and a cross ventilation hole 6 with a diameter of 10M is opened around the lower part. The cross ventilation hole 6 is composed of four 10M diameter wooden sticks. A 10CM paper tube is placed vertically in the center as the central ventilation hole. The bottom combustion layer 5 is filled with straw material with a thickness of about 20CM and compacted. The middle combustion layer 4 is filled with hard wood with a thickness of about 20CM (commonly used branches after pruning are tied tightly). The upper combustion layer 3 and the top covering layer 2 are filled with dense sawdust and easy-to-continue fire materials (commonly used orchard branches crushed sawdust), the top is conical, covered with soil to cover the surface, and leave a top smoke outlet 8. Pull out the bottom wooden sticks, complete the production process, and place them in the orchard channel for use.
[0019] Frost Defense Implementation:
[0020] like Figure 1 As shown, before the frost comes, a methane cassette gas spray gun is used to ignite from the bottom cross ventilation hole 6, the bottom combustion layer 5 burns first, and the combustion starts from the central ventilation hole 1 and burns around. During the combustion process, the sawdust falling from the upper combustion layer 3 and the top semi-enclosed covering layer 2 will have a "covering" effect to prevent excessive combustion. The rising airflow releases smoke from the top smoke outlet 8 through the gap between the upper combustion layer 3 and the top semi-enclosed covering layer 2.
[0021] The utility model provides an effective solution to the orchard frost prevention problem of ordinary growers in small scattered areas. It mainly adopts three densities of smoke-generating combustion materials, and the method of stacking and placing them in layers in the process, with the bottom cross ventilation, the center up and down ventilation, and the top semi-sealed structure, to increase the smoke-generating time. It has the advantages of convenient material acquisition, simple process, low cost, and is suitable for outdoor implementation of ordinary farmers.
