Description

Technical Field

[0001] The invention relates to the technical field of sprinkler irrigation, in particular to a sprinkler irrigation device for forestry planting land. Background Art

[0002] Forestry land is land used exclusively for forestry production. It includes forested land, shrubbery land, sparse woodland, and suitable forest land and non-forested land that do not yet have trees. However, it does not include land with mangroves growing along the coast, forest swamps, shrubbery swamps, greening forest land within towns and villages, trees within the scope of railway and highway land acquisition, and river and ditch embankment forests. Rubber trees are arbor plants, and their planting areas are classified as forest land.

[0003] The natural rubber produced by rubber trees is the main raw material for making rubber, which can be used as a raw material for making paint and soap, high-quality fibers, activated carbon, furfural, etc. After chemical treatment, it can be made into high-end furniture, fiberboard, plywood, pulp, etc. In addition, rubber forests are also sustainable tropical forest ecosystems and are pollution-free and renewable natural resources.

[0004] It is inevitable to ensure that there are no cuts on the trunks of rubber trees when tapping. Frequent cuts can easily cause a large loss of water in the rubber tree and cause dead skin. In order to allow new skin to grow better at the wound and keep the water in the rubber tree from being lost, it is necessary to spray agents in the tapping area. Among them, the tree healing ointment can be used for the cuts caused by tapping, which can keep water from being lost and prevent pollution from external substances. It has the effects of being waterproof, insect-proof and anti-bacterial. The dead skin recovery agent promotes the recovery of the dead skin of rubber trees through spraying and burying, thereby increasing the number of rubber plants that can be tapped and the latex yield.

[0005] However, the rubber tree planting area is densely forested and deep, and the location and range of the rubber tree tapping point will vary according to the tapping standards. The traditional method of spraying chemicals in the forest area is difficult to implement effectively due to the obstruction of trees. At present, the chemical spraying method in the rubber tree tapping point area is mostly done manually, using a spray bottle to spray the chemical to the bark recovery area. In this process, the tapping and maintenance operations of the rubber trees often produce a large amount of travel rejection, the operating personnel have a large workload in a short period of time, and it is difficult to accurately control the spraying amount and coverage of the chemical, which can easily cause omissions in the chemical spraying and affect the rubber tree's own recovery rate and later yield. Summary of the invention

[0006] In order to solve the deficiencies of the prior art, the present invention provides a sprinkler irrigation device for forestry planting land; thereby solving the problem that the traditional method of spraying pesticides in the forest area is difficult to be effectively implemented due to the obstruction of trees, and the current method of spraying pesticides in the rubber tree tapping area is mostly done manually, resulting in a large workload for operators in a short period of time.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 4 As shown, a preferred embodiment of the present invention provides a sprinkler irrigation device for forestry planting, including a liquid medicine tank 2 for containing different medicines, a spraying pipe 3, a bonding plate 4 and a control box 5, and a rubber tree 1 has a tapping hole 10 left after tapping.

[0034] It should be noted that the agent includes a dead skin recovery agent for assisting the recovery of bark at the tapping site and an antibacterial agent for protection, and can also be used to maintain the moisture required for the growth of the rubber tree 1.

[0035] After the rubber tree 1 completes the tapping cycle, it enters the recovery stage. In order to assist the rapid recovery of the bark of the rubber tree 1, different agent bins of the agent bin 2 are filled with agents for assisting the bark recovery. The agents can be the same agent or a mixture of different agents. The spray pipes 3 are distributed on both sides of the tapping port 10, and the agent spraying area of ​​the spray pipes 3 completely crosses the tapping port 10 area from top to bottom.

[0036] Further, such as Figure 3 , Figure 4 and Figure 6 As shown, the spray pipe 3 is arranged at the lower part of the liquid medicine warehouse 2, and two groups of spray pipes 3 are arranged. The two groups of spray pipes 3 are staggered front and back and the two groups of spray pipes 3 are respectively connected to different medicine warehouses in the liquid medicine warehouse 2, and a liquid level sensor is arranged in the liquid medicine warehouse 2.

[0037] During the bark recovery stage of the rubber tree 1, the recovery liquid and the antibacterial liquid are sprayed to the tapping mouth 10 area regularly and quantitatively through the spray pipe 3, while maintaining the water demand required by the bark recovery area, providing nutrition and antibacterial support for it. During the daily maintenance stage, when the rubber tree 1 planting area encounters low precipitation, the water pipe can be connected to the liquid medicine tank 2, so that the liquid medicine tank 2 becomes a temporary water storage container, and regular clean water spraying is carried out, so as to increase the reasonable humidity of the rubber tree 1 planting area while ensuring the necessary water supply for the growth of the rubber tree 1. By directly spraying the trunk, the sprayed clean water can flow along the trunk to the root area, thereby forming a fixed-point water supply, reducing the amount of water escape during the sprinkler irrigation process, and saving water.

[0038] Further, such as Figures 2 to 4 As shown, the control box 5 is fixedly mounted on the bonding plate 4, and the control box 5 is installed with batteries, a controller, a solenoid valve and an air chamber required for the sprinkler irrigation operation. The solenoid valve is connected to the air chamber, and a push-type air injection plug 51 is movably installed on the air chamber.

[0039] The battery can be a replaceable storage battery according to the planting area of ​​the rubber tree 1 and the frequency of rubber tapping, so as to ensure sufficient power supply during outdoor work and the need for rapid replacement in the later stage. During the rubber tapping operation, the operator presses the gas injection plug 51 back and forth to make the air pressure in the air chamber reach a predetermined value. The mechanical air supply method is adopted to reduce the dead weight and the probability of failure in the later stage. The bark of the rubber tree 1 recovers quickly after rubber tapping, and the reserved gas volume in the air chamber can provide sufficient power supply during the entire period of spraying medicine or water.

[0040] Further, such as Figures 2 to 5 As shown, the medicine liquid tank 2 is fixedly installed in the middle of the bonding plate 4, and a roughness clamp 41 is movably installed on the side of the bonding plate 4 facing away from the medicine liquid tank 2. Two groups of roughness clamps 41 are symmetrically arranged on the side positions of the bonding plate 4. The roughness clamps 41 are slidably matched with the bonding plate 4, and a tension spring 42 is connected between the roughness clamp 41 and the bonding plate 4. The end of the roughness clamp 41 away from the bonding plate 4 is an arc-shaped curved structure, and the arc-shaped inner side surface of the roughness clamp 41 is evenly provided with columnar bars 43, and the columnar bars 43 are made of elastic material.

[0041] The tapping frequency and rubber yield of rubber trees 1 are affected by their age and trunk diameter. The tapping standard is generally determined based on tree circumference, followed by age.

[0042] Data shows that the ability of rubber trees with a circumference of 50 cm to produce nutrients is 29% higher than that of 40 cm; after the 50 cm rubber trees are tapped, the circumference growth is only 5.9% less than that of the untaped control trees, while the 40 cm tapped trees are about 18% less.

[0043] Harvesting starts when the tree circumference reaches 50 cm. This not only has little impact on the growth of the rubber tree, but also increases the yield.

[0044] When the tree circumference reaches 50 cm, the bark thickness is suitable for rubber tapping. Generally, the bark thickness of rubber tapping trees is about 0.7 cm, so that the consumption and regeneration of bark are balanced, ensuring that there is enough bark that meets the standards for rubber tapping and the economic value of bark is used reasonably. When the bark is too thin, it is easy to flow out, which is easy to damage the tree, and the regenerated bark is poor, which affects future production.

[0045] In order to realize batch monitoring of rubber planting forestry land and formulate reasonable sprinkler irrigation and tapping frequencies, the symmetrically installed thickness clamps 41 can be clamped on the trunk of the rubber tree 1 in an embracing manner, and the columnar bars 43 can increase the clamping firmness while avoiding leaving indentations on the trunk. Through the one-to-one corresponding bundling combination between the rubber tree 1 and the liquid medicine tank 2, the operator can proportion the type or dosage of sprinkler irrigation agents according to the specific growth conditions of different rubber trees 1, thereby improving the accuracy of sprinkler irrigation and avoiding waste.

[0046] Further, such as Figure 5 As shown, a unloading pipe 411 is installed on the roughness clamp 41 by threaded fitting, one end of the tension spring 42 is fixedly connected to the middle of the bonding plate 4, and the other end of the tension spring 42 is fixedly connected to the bottom of the unloading pipe 411.

[0047] When the tree circumference is constant, the expansion and contraction amount of the tension spring 42 can be adjusted by rotating the unloading tube 411, thereby realizing the adjustment of the tension of the tension spring 42, so that the thickness clamp 41 and the tree trunk maintain a reasonable contact clamping pressure. At the same time, through the adaptive elastic expansion and contraction ability of the tension spring 42, it can adapt to the changes in the tree circumference during the later growth process of the tree trunk, and further improve the long-term stability of operation during the liquid medicine or clean water sprinkler irrigation operation.

[0048] Further, such as Figure 5 As shown, a scale line 44 is provided on the upper portion of the bonding plate 4 , and a pointer piece 45 for pointing to the scale line 44 is fixedly installed on the upper portion of the roughness clamp 41 .

[0049] In the same forest section, when the budding trees are 100 cm above the ground, the excellent seedling trees are 50 cm above the ground, the tree circumference is 50 cm, and the rubber trees in the areas with severe wind and severe cold damage and the rubber trees that are ten years old and have a tree circumference of more than 45 cm account for 50% of the number of trees in the forest section, the official harvesting will be started. The harvesting rate calculation method is as follows: , In order to determine the cutting rate of the rubber tree 1 planting area, when the thickness clamp 41 completes the clamping operation on the rubber tree trunk, the pointer piece 45 points to a certain scale position on the scale line 44. At this time, the tree circumference of the tree is recorded and included in the statistics and subsequent monitoring data tables. When the girth of the rubber tree 1 grows thicker, the thickness clamp 41 extends accordingly and drives the pointer piece 45 to move. During the subsequent tapping or inspection process, the operating personnel can intuitively observe the changes in the tree girth, thereby making a quick calculation of the cutting rate of the rubber tree 1 planting area. The nutrient or clean water supply ratio in the subsequent sprinkler irrigation process can also be formulated through the changes in the tree girth, further improving the tapping and maintenance efficiency of the rubber tree 1 and reducing the labor intensity of the operating personnel.

[0050] Further, such as Figures 1 to 4 As shown, a rain shield rod 412 is fixedly installed at the arc-shaped end of the roughness clamp 41. The rain shield rod 412 extends upward along the axial direction of the roughness clamp 41. The rain shield rod 412 is respectively located on both sides of the bonding plate 4, and a rain shield plate 413 is commonly installed at the upper ends of the two rain shield rods 412. The rain shield plate 413 is in an incomplete cone shape and surrounds the bonding plate 4 and the top of the roughness clamp 41. The roughness clamp 41 and the rain shield plate 413 are both made of rubber or plastic.

[0051] The amount of rainfall in the rubber tree 1 planting area is mostly sufficient. In order to avoid the dilution and deterioration of the rubber or sprinkler irrigation agent caused by rain dripping during rubber tapping or bark maintenance, the sprinkler irrigation and rubber tapping areas can be shielded and protected by the rain shield 413, and the dripping rain, dead branches or bird droppings and other falling objects can be reasonably guided to the outside of the sprinkler irrigation or tapping area, thereby forming daily protection for the sprinkler irrigation device and the rubber tapping port 10 area, and improving the operating stability of the sprinkler irrigation device.

[0052] Further, such as Figures 6 to 8 As shown, a cross bar 46 is fixedly installed at the lower part of the bonding plate 4, and a deflection shaft 461 is symmetrically installed at both ends of the cross bar 46 by rotational cooperation. The deflection shaft 461 passes through the cross bar 46, and the spray pipe 3 is fixedly installed at one end of the deflection shaft 461 close to the roughness clamp 41, and a quantitative bin 47 is fixedly installed at the other end of the deflection shaft 461. The lower part of the quantitative bin 47 is connected with the spray pipe 3 through a liquid distribution pipe 471, and the upper part of the quantitative bin 47 is connected with the liquid medicine bin 2 through a dripping pipe 21. The quantitative bin 47 is a silo-shaped structure, and a yield groove is provided on the middle and upper arc outer wall of the quantitative bin 47, and a yield piece 472 is slidably installed in the yield groove. The end of the dripping pipe 21 is fixedly connected to the yield piece 472, and a dripping notch 473 is provided in the middle of the yield groove, and the end of the dripping pipe 21 is connected to the yield piece 472. A dripping notch 473 is provided in the middle of the yield groove, and the end of the dripping pipe 21 is connected to the inner cavity of the quantitative bin 47 through the dripping notch 473.

[0053] In the initial state, the spray pipe 3 is vertically placed on both sides of the rubber tapping port 10. At this time, the liquid medicine bin 2, the dripping pipe 21, the dripping notch 473 and the inner cavity of the quantitative bin 47 are in a conducting state. In order to achieve the precise and quantitative spraying requirements of the medicine, the medicine or clean water stored in the liquid medicine bin 2 can enter the quantitative bin 47 through the dripping pipe 21 and the dripping notch 473 under the action of gravity. When the quantitative bin 47 is filled with a predetermined volume of medicine, the medicine in the liquid medicine bin 2 stops flowing downward. At this time, the volume of medicine carried in the quantitative bin 47 is the amount of medicine used for a single spraying operation.

[0054] Further, such as Figure 7 and Figure 8 As shown, a discharge shaft 474 is coaxially mounted on the inner side of the quantitative chamber 47 by means of rotational cooperation, a discharge sheet 475 is fixedly mounted on the side wall of the discharge shaft 474 along the vertical axis direction, the discharge sheet 475 slides and fits with the inner wall of the quantitative chamber 47, a baffle 476 is fixedly mounted on the inner side of the quantitative chamber 47 along the vertical axis direction, and the baffle 476 slides and fits with the side wall of the discharge shaft 474, a spring 477 is connected between the baffle 476 and the discharge sheet 475, the spring 477 is arc-shaped, and the spring 477 is arranged to fit with the inner wall of the quantitative chamber 47, and the drip tube 2 1 and the port of the distribution pipe 471 are coaxial at the upper and lower positions of the quantitative chamber 47, and the baffle 476 and the drainage sheet 475 are both located on one side of the coaxial axis of the drip tube 21 and the distribution pipe 471, and an angle α with an angular range of motion of 60 degrees to 300 degrees is reserved between the baffle 476 and the drainage sheet 475. The inner cavity of the quantitative chamber 47 forms two independent chambers under the separation effect of the baffle 476 and the drainage sheet 475. The chamber where the spring 477 is located is the first chamber 478, and the chamber connected to the distribution pipe 471 is the second chamber 479.

[0055] In the initial state, the medicine flowing into the quantitative bin 47 is stored in the second chamber 479, and the first chamber 478 is in a dry state. By selecting springs 477 with different lengths or elastic coefficients, the angle α between the baffle 476 and the drainage sheet 475 can be adjusted. When the first chamber 478 shrinks, the second chamber 479 expands accordingly, thereby increasing the subsequent amount of stored medicine. Conversely, the amount of stored medicine decreases. Therefore, the amount of irrigation for restoring the medicine can be further reasonably adjusted according to the tree circumference or rubber tapping frequency to improve rationality.

[0056] A cylinder 48 is fixedly installed at the lower part of the bonding plate 4, and the telescopic end of the cylinder 48 is an "L"-shaped structure. A waist-shaped groove is opened at the upper end of the spray pipe 3 along its axial direction, and the telescopic end of the cylinder 48 slides through the waist-shaped groove on the spray pipe 3. A first air distribution pipe 481 is connected between the cylinder 48 and the electromagnetic valve in the control box 5. A splitter tube 49 is fixedly installed in the middle of the cross bar 46. The middle part of the splitter tube 49 is connected to the electromagnetic valve in the control box 5 through the second air distribution pipe 491. The end of the splitter tube 49 penetrates The quantitative bin 47 and the end of the diverter cylinder 49 are rotatably connected to the discharge shaft 474, the discharge shaft 474 is provided with an air hole 470 on the side facing the first chamber 478, and the air hole 470 is communicated with the diverter cylinder 49, the middle and lower parts of the spray pipe 3 are evenly provided with nozzles along its axial direction, a plugging piece 460 is fixedly installed on the cross block 46, the plugging piece 460 is vertically downward, and the side wall of the plugging piece 460 is in contact with the nozzle port on the spray pipe 3, and the middle part of the spray pipe 3 and the middle part of the plugging piece 460 are symmetrically provided with magnetically adsorbed permanent magnets.

[0057] In order to achieve complete coverage of the agent in the tapping port 10 area by spray irrigation, when the liquid level sensor detects that the quantitative replenishment of the agent is completed, the cylinder 48 is started to work, and the spray pipe 3 is pushed to deflect through the telescopic end of the cylinder 48, so that the spray pipe 3 is turned to the front area of ​​the tapping port 10, until the two spray pipes 3 cross and overlap each other to form an "X"-shaped deflection. During the deflection of the spray pipe 3, it drives the quantitative bin 47 to rotate synchronously through the deflection shaft 461. At this time, the yielding piece 472 and the quantitative bin 47 rotate relative to each other. When the dripping tube 21 moves out of the dripping slot 473 area, the port of the dripping tube 21 is attached to the yielding slot and enters a blocked state. Subsequently, the solenoid valve is started to work, and the high-pressure gas pre-stored in the gas bin is delivered to the second gas distribution through the solenoid valve. In the tube 491, the air flow flows to the drainage shafts 474 on both sides after the diversion effect of the diversion tube 49, and is discharged from the air hole 470 to the first chamber 478. At this time, the air pressure in the first chamber 478 increases, thereby pushing the drainage sheet 475 to rotate in the direction away from the baffle 476. In this process, the first chamber 478 gradually expands, and the second chamber 479 gradually shrinks. In the process of shrinking, the second chamber 479 squeezes the quantitative medicine stored therein to the distribution pipe 471, and enters the spray pipe 3 through the distribution pipe 471, and is sprayed to the rubber tapping port 10 area through the nozzle in the middle and lower part of the spray pipe 3. In the process of deflection of the drainage sheet 475, it slides in contact with the inner wall of the quantitative bin 47, thereby scraping and cleaning the residual medicine inside the quantitative bin 47.

[0058] By controlling the rate of gas introduction into the first chamber 478, the spray pressure of the liquid medicine at the spray pipe 3 can be further adjusted, thereby adjusting the length of its spray path. By means of pressurization, the impact force of the liquid medicine in contact with the tapping mouth 10 area is increased, thereby causing the medicine to diffuse during the contact and collision process, thereby improving the sufficient medicine spraying operation on the rugged bark in the tapping mouth 10 area. In addition, the air pressure state in the first chamber 478 can be adjusted by controlling the amount of gas introduced into the first chamber 478, thereby achieving adjustment of the volume of the first chamber 478 to adapt to the demand for medicine required when the tree circumference growth changes or the range of the tapping mouth 10 changes.

[0059] During the deflection and irrigation of the spray pipe 3, the spray pipe 3 and the plugging piece 460 are misaligned, and the plugging piece 460 gradually breaks away from the extrusion contact with the nozzle. The nozzle opens, and the agent is sprayed out from the nozzle position. When the irrigation operation is completed, the spray pipe 3 is put into a vertical state again by controlling the operation of the cylinder 48. At this time, under the magnetic effect of the permanent magnet, the plugging piece 460 fits against the side wall of the spray pipe 3 and completes the plugging operation of the nozzle.

[0060] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
