Description

Technical Field

[0001] The invention relates to the technical field of fruit tree cultivation, in particular to a late frost resistance device for walnut trees. Background Art

[0002] Walnut trees mainly grow in arid and semi-arid areas in the north. They are light-loving and cold-resistant and are tall trees.

[0003] There are many cold waves in the northern region in spring. Although walnut trees are cold-resistant, their cold tolerance decreases during the spring budding stage. They are susceptible to late frosts at night or when cold waves invade, resulting in reduced production. At present, the method of preventing late frost damage is to spray nutrient solution and other liquids to help walnut trees resist the cold. The spraying of nutrient solution often requires manual spraying. However, walnut plantations are large in scale. Once the temperature drops, the spraying workload of the staff is large. Summary of the invention

[0004] The embodiment of the present invention provides a walnut tree anti-late frost device, which can effectively protect walnut trees from late frost. The technical solution of the present invention is as follows: A walnut tree anti-late frost device comprises a support column, a reaction chamber and a film bag; The support column is fixed on the ground near the walnut tree, the reaction chamber is installed on the support column, the film bag is installed on the inner wall of the top of the reaction chamber, the film bag is filled with solid particles including calcium oxide, the reaction chamber is penetrated by a puncture catheter, the puncture catheter faces the film bag, the reaction chamber is provided with a plurality of through holes, a liquid partition is also installed in the reaction chamber, the liquid partition separates the bottom of the reaction chamber into a first space and a second space for containing liquid, the liquid contained in the first space includes water, and the liquid contained in the second space includes nutrient solution, the reaction chamber is penetrated by an infusion tube, one end of the infusion tube is inserted into the nutrient solution, and the other end of the infusion tube passes through the reaction chamber toward the branches and / or trunk of the walnut tree.

[0005] In a possible design, the puncture catheter abuts against the film bag, one end of the puncture catheter abutting against the film bag is higher than the other end thereof located outside the reaction chamber, the puncture catheter is filled with water, and the other end of the puncture catheter is installed with a sealing plug; When the ambient temperature is below the freezing point, the water in the puncture catheter freezes and increases in volume to puncture the film bag.

[0006] In a possible design, a heat-insulating layer is laid inside the reaction chamber.

[0007] In a possible design, the liquid contained in the first space further includes hydrochloric acid, and the solid particles filled in the film bag further include calcium carbonate and / or sodium carbonate.

[0008] In a possible design, the solid particles are partially or completely covered with a coating of varying thicknesses.

[0009] In a possible design, the support column and the reaction chamber are rotatably connected, and the support column is a shaft pin structure.

[0012] In a possible design, one end of the infusion tube is located at the bottom of the second space, and the other end of the infusion tube is located lower than the bottom of the second space.

[0013] In one possible design, the film bag is filled with gas to expand it.

In addition, because the through hole is small, the air pressure in the reaction chamber is greater than the external air pressure within a certain period of time (before the reaction chamber and the external air pressure are balanced), so that within this time, the expanded hot air flow also increases the air pressure inside the reaction chamber, and then the air pressure acts on the nutrient solution in the second space, so that the nutrient solution in the second space is sprayed onto the walnut tree through the infusion tube. The entire process only requires puncturing the film bag, which does not require complicated procedures or an electrical system. After the film bag is replaced and filled with raw materials, it can be reused, which greatly reduces the number of manpower and improves the efficiency of spraying the nutrient solution, achieving efficient protection against late frost for walnut trees.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] like Figure 1 As shown, this embodiment provides a walnut tree anti-late frost device, including a support column 1, a reaction chamber 2 and a film bag 3; A support column 1 is fixed on the ground near a walnut tree, a reaction chamber 2 is mounted on the support column 1, a film bag 3 is mounted on the inner wall at the top of the reaction chamber 2, solid particles 4 including calcium oxide are filled inside the film bag 3, a puncture catheter 9 is penetrated by the reaction chamber 2, the puncture catheter 9 faces the film bag 3, a plurality of through holes 10 are opened in the reaction chamber 2, a liquid partition 5 is also installed in the reaction chamber 2, the liquid partition 5 separates the bottom of the reaction chamber 2 into a first space 6 and a second space 7 for containing liquid, the liquid contained in the first space 6 includes water, and the liquid contained in the second space 7 includes nutrient solution, an infusion tube 8 is penetrated by the reaction chamber 2, one end of the infusion tube 8 is inserted into the nutrient solution, and the other end of the infusion tube 8 passes through the reaction chamber 2 toward the branches and / or trunk of the walnut tree.

[0020] In this embodiment, a plurality of walnut tree anti-late frost devices are placed near different walnut trees. When anti-late frost is needed, the film bag 3 is punctured by the puncture conduit 9, and the calcium oxide particles in the film bag 3 fall into the water in the first space 6. On the one hand, the calcium oxide particles react with water to release heat, and the generated heat heats the air in the reaction chamber 2, causing it to heat up and expand. The expanded hot air flow is discharged to the walnut tree through the through hole 10, providing heat for the walnut tree. On the other hand, since the through hole 10 is small, the air pressure in the reaction chamber 2 is greater than the outside air pressure within a certain period of time (before the reaction chamber 2 is balanced with the outside air pressure). Therefore, the expanded hot air flow during this time also increases the air pressure inside the reaction chamber 2, and then the air pressure acts on the nutrient solution in the second space 7, so that the nutrient solution in the second space 7 is sprayed onto the walnut tree through the infusion tube 8. The whole process only needs to puncture the film bag 3, without complicated procedures and power systems. After replacing the film bag 3 and filling it with raw materials, it can be reused, which greatly reduces the number of labor and improves the spraying efficiency of the nutrient solution. When the walnut tree needs to resist late frost when it is manually determined according to the ambient temperature, or when the temperature drops to below zero, the walnut tree needs to resist late frost. The film bag 3 is punctured by the puncture conduit 9, which can be manually operated, or the puncture conduit 9 can automatically puncture the film bag 3 when the ambient temperature reaches the freezing point.

[0021] It should be noted that an air guide tube with multiple air holes can be provided at the through hole 10. The air guide tube can be hung under the branch so that the hot air discharged from the through hole 10 can be directly output to the new buds on the branch through the air holes of the air guide tube.

[0022] In this embodiment, the material of the film bag 3 can be a rubber material, which is elastic and easy for the solid particles 4 inside to spray out when it breaks; the material of the film bag 3 can also be a polyvinyl chloride material, which cracks at low temperatures; the material of the film bag 3 can also be a cellulose film, which is brittle and easy to break.

[0023] In some embodiments of the present invention, the puncture catheter 9 abuts against the film bag 3, one end of the puncture catheter 9 abutting against the film bag 3 is higher than the other end thereof located outside the reaction chamber 2, the puncture catheter 9 is filled with water, and a sealing plug is installed at the other end of the puncture catheter 9; when the ambient temperature is below the freezing point, the water in the puncture catheter 9 freezes and its volume increases to puncture the film bag 3.

[0024] In this embodiment, the puncture tube 9 is thinner, so that the frozen water is in the shape of a needle, which is convenient for puncturing the film bag 3. When the temperature drops, the water in the puncture tube 9 freezes, and its volume expands after freezing. Due to the limitation of the puncture tube 9, the ice can only extend along the axial direction of the puncture tube 9, and finally puncture the film bag 3.

[0025] It should be noted that the thinner the puncture catheter 9 is, the longer the distance the interior thereof will stretch after freezing.

[0026] It is understandable that in order to prevent water leakage in the puncture catheter 9, one end of the puncture catheter 9 that abuts against the film bag 3 is attached to the film bag 3 through a sealing tape. The other end of the puncture catheter 9 located outside the reaction chamber 2 is used to fill water into the puncture catheter 9. Since this end opens downward, in order to overcome gravity and fill water into it, a water injection port can be set at the upper part of the tube wall of the puncture catheter 9. One end of the puncture catheter 9 is a plunger structure. After a certain amount of water is injected into the puncture catheter 9 through the water injection port, the water injection port is sealed. Similar to a syringe, the plunger is pushed to fill the puncture catheter 9 with water, and then the end of the puncture catheter 9 located inside the reaction chamber 2 is bonded to the film bag 3 through a sealing tape or other items.

[0027] It can be understood that, in order to facilitate operation, a plurality of openable and closable door structures are provided on the reaction chamber 2. For example, an openable and closable door is provided on the side of the reaction chamber 2 to facilitate the filling of raw materials. In order to facilitate the injection of liquid, the first space 6 and the second space 7 can be provided with a liquid inlet and a liquid outlet. The specific structure is well known to those skilled in the art and will not be described in detail here.

[0028] In some embodiments of the present invention, a heat-insulating layer is laid inside the reaction chamber 2. After the reaction occurs inside the reaction chamber 2, hot air is continuously generated and discharged to the outside. In order to save heat, a heat-insulating layer can be laid inside the reaction chamber 2, for example, asbestos, foam or quartz fiber.

[0029] In some embodiments of the present invention, the liquid contained in the first space 6 further includes hydrochloric acid, and the solid particles 4 filled in the film bag 3 further include calcium carbonate and / or sodium carbonate.

[0030] In this embodiment, in order to further increase the continuous output of hot air flow in the reaction chamber 2, hydrochloric acid reacts with carbonate to generate a large amount of carbon dioxide gas. The large amount of generated gas can not only continuously provide hot air flow, but also form a continuous high pressure to provide power for the discharge of the nutrient solution in the second space 7.

[0031] In some embodiments of the present invention, the solid particles 4 are partially or completely coated with coatings of different thicknesses. For example, the coating may be a HPMC (hydroxypropyl methylcellulose) film coating or sugar. Coatings of different thicknesses dissolve at different rates, i.e., at different times, some of the solid particles 4 react with the liquid in the first space 6, thereby making the reaction in the first space 6 continuous and not too intense.

[0032] It is understandable that a screen or a funnel may be provided above the liquid surface of the first space 6 so that the solid particles 4 continuously fall into the liquid in the first space 6 .

[0033] In some embodiments of the present invention, the support column 1 and the reaction chamber 2 are rotatably connected, and the support column 1 is a shaft pin structure.

[0034] In this embodiment, the axle pin structure can adjust the pitch angle of the reaction chamber 2 , and the rotational connection between the support column 1 and the reaction chamber 2 can adjust the azimuth angle of the reaction chamber 2 .

[0035] In some embodiments of the present invention, a multi-hole nozzle is installed at the other end of the infusion tube 8. The multi-hole nozzle can be more conducive to the uniform spraying of the nutrient solution over a large area.

[0036] In some embodiments of the present invention, the liquid isolating member 5 comprises a cylinder, the interior of the cylinder is the second space 7, and the exterior of the cylinder is the first space 6.

[0037] In this embodiment, the second space 7 formed by the cylinder is used to hold the nutrient solution, and its cross-sectional area is smaller than that of the second space 7 of other shapes. The same volume of nutrient solution can obtain a relatively higher liquid level in the second space 7 of the cylinder with a smaller cross-sectional area. In this way, the liquid in the second space 7 can be more easily discharged by using the infusion tube 8 as a communicating vessel.

[0038] In some embodiments of the present invention, one end of the infusion tube 8 is located at the bottom of the second space 7, and the other end of the infusion tube 8 is located below the bottom of the second space 7. In this way, the nutrient solution in the second space 7 can be completely discharged by utilizing the communicating vessel principle.

[0039] In some embodiments of the present invention, the film bag 3 is filled with gas to expand it, so that the expanded film bag 3 is easier to be punctured.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
