Description

Technical Field

[0001] This invention belongs to the field of farmland water conservancy technology, specifically relating to a straw treatment irrigation device. Background Technology

[0002] In an era of limited productivity, straw was primarily used as livestock feed or domestic fuel. However, collecting, bundling, and transporting straw from farmland is extremely time-consuming and labor-intensive. The increasing proportion of elderly people in rural areas further complicates this process. Currently, rural areas rely heavily on more readily available energy sources such as coal, natural gas, and electricity to meet daily needs. This results in large amounts of straw being discarded in farmland, making the disposal of excess straw increasingly important. As methods of straw treatment, such as field burning, open composting, and pulverizing and returning to the field, reveal a series of problems, the development of eco-friendly and simple straw treatment technologies has become crucial.

[0003] Chinese invention patent specification with publication number CN106385842A, publication date February 15, 2017, and application number 2016107648546 discloses a method and application for returning straw to the field. This invention patent mainly utilizes a composite harvester to crush rice straw and spread it evenly in the field. Before plowing, urea and soil activator are added, and then the straw is rotary tilled. This technology improves soil porosity, makes the soil loose and easy to cultivate, and can also adjust soil alkalinity.

[0004] Chinese invention patent specification CN106608774A, published on May 3, 2017, with application number 201611198292X, discloses a straw fertilizer for improving soil structure. The main raw materials are straw, rapeseed meal, peat moss, nectar pollen, and polyvinyl alcohol. This technology is low-cost and increases soil organic matter and beneficial microorganisms, preventing soil compaction, and thus has significant economic and ecological benefits.

[0005] Chinese invention specification CN107434520A, published on December 5, 2017, and application number 2016103582855 discloses a culture medium for white lingzhi mushrooms using cotton stalks and monk fruit residue as the carbon source. The main components are cotton stalk fragments, monk fruit residue, wheat bran, etc., which greatly reduces the cost of cultivating white lingzhi mushrooms.

[0006] Chinese invention patent specification with publication number CN106313769A, publication date January 11, 2017, and application number 2015103440506 discloses a straw modified composite material, which is a multi-layer composite structure, mainly including a wear-resistant layer, a color film layer, a substrate, and a base material. This invention overcomes the defects of straw fibers and has advantages in terms of strength, toughness, and wear resistance.

[0007] Chinese invention patent specification with publication number CN103718787A, publication date April 16, 2014, and application number 2012104136317 discloses a method for increasing corn yield by covering and returning whole corn stalks to the field. The main method is to cut the corn stalks, leave the corn stubble, cover one corn ridge every meter, and immediately dig up the stubble soil to stabilize the corn stalks after covering. The beneficial effects of this invention are drought prevention, wind protection, and fertilization.

[0008] While existing technologies have made some progress, the following problems still exist:

[0009] (1) Although there have been some technological advancements in the method of returning straw to the field, such as improving soil structure and fertilizing the field, the problem of the limited amount of straw returned to the field has not been well solved. In addition, the straw degradation efficiency is low and the absorption rate by farmland is low.

[0010] (2) Straw is used as a raw material for agricultural production or building materials, and it is difficult to promote its widespread application. Summary of the Invention

[0011] The purpose of this invention is to provide a straw treatment irrigation device to solve the technical problems of low straw degradation efficiency and low absorption rate in existing straw treatment methods.

[0012] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a straw treatment irrigation device, comprising:

[0013] Irrigation facilities;

[0014] A straw processing mechanism is installed on the irrigation mechanism, and the straw processing mechanism includes:

[0015] The first receiving cavity is provided with heat-insulating partition assemblies spaced apart. A mixture of straw and microbial degradation material is placed between the heat-insulating partition assemblies. A mixture of nutrient material and earthworms is placed between the heat-insulating partition assemblies and the first receiving cavity. The heat-insulating partition assemblies are provided with through holes for earthworms to pass through.

[0016] The first receiving cavity includes a concrete-enclosed cavity and a phase change energy storage interlayer disposed within the concrete-enclosed cavity. The phase change energy storage interlayer is used for heat preservation of the first receiving cavity.

[0017] An outlet hole is provided on the receiving cavity for discharging the humus and earthworm castings generated from the degradation of straw into the irrigation mechanism.

[0018] This invention uses a combination of microorganisms and earthworms to degrade straw, which is non-toxic, harmless, and does not cause environmental pollution. By using a phase change energy storage interlayer and thermal insulation partition components, this invention ensures that the internal temperature and humidity of the straw treatment device are suitable for the continuous reproduction and growth of earthworms, thereby improving the efficiency of straw degradation. Furthermore, the earthworm castings and humus produced by the earthworms digesting the straw are flushed into the farmland with irrigation water, forming fertilizer for crops, which improves the efficiency of straw degradation being absorbed by the farmland.

[0019] This invention utilizes earthworms to digest straw through holes in the heat-insulating partition assembly. At the same time, microorganisms degrade the straw, and the resulting mixture of humus and earthworm excrement flows through an outlet in the receiving cavity into the irrigation mechanism. It is then flushed into the farmland by irrigation water and becomes fertilizer for crops.

[0020] The present invention allows crop straw to degrade on irrigation ditches, without occupying arable land or requiring long-distance transportation. Furthermore, the degraded humus is flushed into the farmland with irrigation water, serving as fertilizer for crops.

[0021] To address the technical problem of uneven dispersion of humus and earthworm castings in irrigation water due to their inconsistent particle size, resulting in low crop absorption rates, this invention employs the following technical solution: the straw processing mechanism is equipped with a crushing mechanism, including:

[0022] The mounting ring seat is disposed on the outlet of the receiving cavity one;

[0023] A crushing component is disposed on the mounting ring seat. The crushing component includes a rotating shaft. The rotating shaft is rotatably disposed at the center of the mounting ring seat. A blade is disposed on the rotating shaft for rotating and crushing the humus generated by the degradation of straw and earthworm castings.

[0024] A power assembly is disposed at the lower end of the rotating shaft and located within the irrigation mechanism. The power assembly is driven to rotate by the water flow within the irrigation mechanism, thereby driving the rotating shaft to rotate.

[0025] The mixture of humus and earthworm castings produced by straw degradation is finely chopped by the blades and flows through the outlet into the irrigation system, where it is flushed into the farmland by irrigation water, becoming fertilizer for crops. This invention uses water flow within the irrigation system to drive the blades to rotate and finely chop the humus and earthworm castings, facilitating their even dispersion in the irrigation water and absorption by crops, thus improving utilization efficiency.

[0026] To address the technical problem of undegraded straw flowing out of the outlet of the receiving cavity, this invention employs the following technical solution: a filter assembly is installed on the mounting ring to prevent the outflow of undegraded straw. The filter assembly is preferably a mesh cover, which effectively prevents the outflow of undegraded straw.

[0027] To address the technical challenge of implementing the power component, this invention employs the following solution: the power component includes blades evenly distributed circumferentially on the rotating shaft, and the blades are vertically positioned. Water flow within the irrigation mechanism drives the blades to rotate, which in turn drives the rotating shaft to rotate, thereby rotating the blades to finely chop humus and earthworm castings.

[0028] To address the technical issues related to the proportions of nutrient materials and earthworm mixtures, and straw and microbial degradation materials mixtures, this invention adopts the following technical solution: the nutrient materials and earthworm mixture comprises any one or any combination of two or three of soil, poultry manure, and livestock manure, with a weight ratio of nutrient materials to earthworms of (80%–90%): (20%–10%).

[0029] In the mixture of straw and microbial degradable material: the microbial degradable material is any one or any two or three or four of lactic acid bacteria, Bacillus subtilis, Trichoderma, and Proteobacterium, and the weight ratio of straw to microbial degradable material is (99.9% to 99.8%): (0.01% to 0.02%).

[0030] To address the problem of pollution caused by the direct discharge of waste gas generated during straw processing into the atmosphere, the present invention adopts the following technical solution: a waste gas treatment mechanism is installed on the straw processing mechanism to treat the waste gas generated by the straw processing mechanism during straw degradation.

[0031] To address the technical problem of how to implement a waste gas treatment mechanism, the present invention adopts the following technical solution, wherein the waste gas treatment mechanism includes:

[0032] The second receiving cavity has an air guide hole at its bottom corner.

[0033] The second receiving cavity is provided with partitions, a catalytic oxidant is placed between the partitions, and a carbon dioxide curing agent is placed between the partitions and the second receiving cavity; vent holes are provided at the ends of the partitions, and the vent holes of adjacent partitions are arranged oppositely to form an S-shaped air passage.

[0034] This invention reduces carbon emissions by converting a small amount of methane waste gas generated from straw degradation into water and carbon dioxide gases through a catalytic oxidant under sunlight. Simultaneously, the carbon dioxide solidifying agent solidifies the gas to generate crop fertilizer, which can be applied to the fields to support crop growth.

[0035] To address the technical problems of short catalytic oxidation time and low catalytic oxidation degree of waste gas in the waste gas treatment device, this invention adopts the following technical solution: a pressure relief component is installed on the second receiving cavity. This invention, through the setting of a gas pressure relief valve, allows the waste gas to pass through the waste gas treatment device under certain resistance, thereby extending the catalytic oxidation time of the waste gas in the waste gas treatment device and improving the catalytic oxidation degree.

[0036] To address the technical problem of incomplete catalytic oxidation caused by sunlight exposure, this invention employs the following technical solution: a lighting component is installed on the waste gas treatment device to provide illumination; the lighting component includes an ultraviolet lamp connected to a power supply component. This invention adds a lighting component to the waste gas treatment device, and the combined illumination of the lighting component and sunlight can meet the catalytic oxidation requirements of waste gas for 24 hours.

[0037] To address the high cost of connecting power lines to farmland, this invention employs the following technical solution: the power supply assembly includes a solar panel, a controller, and a battery, with the battery connected to the lighting assembly. This invention utilizes solar-generated electricity to power the lighting assembly, resulting in energy savings, environmental friendliness, and low cost.

[0038] To address the technical problems of low strength and short lifespan of existing concrete formulas used in straw treatment irrigation devices, the present invention adopts the following technical solution: the irrigation mechanism, the concrete encapsulation interlayer of the first accommodating cavity of the straw treatment mechanism, and the second accommodating cavity of the waste gas treatment mechanism are all integrally cast from ultra-high performance concrete.

[0039] The formula for the ultra-high performance concrete is as follows (by weight percentage): cement 48.03%–23.45%, ultrafine limestone powder 2.40%–4.69%, ultrafine metakaolin 7.20%–9.38%, quartz sand 28.82%–46.90%, copper-plated steel fiber 3.75%–7.32%, water 9.22%–7.50%, and polycarboxylate superplasticizer 0.58%–0.75%.

[0040] The cement is 52.5 or 62.5 grade Portland cement;

[0041] The fineness of the ultrafine limestone powder is 1250 mesh to 2000 mesh;

[0042] The fineness of the ultrafine metakaolin is 1250 mesh to 2000 mesh;

[0043] The quartz sand is 40 mesh to 140 mesh;

[0044] The parameters of the copper-plated steel fiber are: length 6mm~13mm, diameter 0.2mm~0.3mm, and corrugated shape;

[0045] The water reduction rate of the polycarboxylate superplasticizer is over 30%.

[0046] This invention improves the strength of concrete by optimizing the concrete formula, using higher-strength cement, increasing the fineness of ultrafine limestone powder and ultrafine metakaolin, increasing the mesh size of quartz sand, and adding copper-plated steel fibers.

[0047] To address the technical problem of how to manufacture the receiving cavity of the straw processing mechanism, the present invention adopts the following technical solution: the method for preparing the receiving cavity of the straw processing mechanism is as follows:

[0048] (1) The production temperature is controlled at 10℃~20℃, and the phase change energy storage material is made into a thin sheet;

[0049] (2) The cement, the ultrafine limestone powder, the ultrafine metakaolin, and the quartz sand are placed into a mixing device and dry-mixed for 1 min to 2 min. Half of the water and the polycarboxylate superplasticizer are added to the mixing device and stirred for 3 min to 4 min. The remaining water and the polycarboxylate superplasticizer are added and stirred for 5 min to 6 min. The copper-plated steel fiber is added and stirred for 2 min to 3 min to obtain ultra-high performance concrete.

[0050] (3) Place the straw processing mechanism mold on the vibrating table, first pour the lower cover plate of the first cavity, then insert the phase change energy storage paraffin into the center of the mold to form a phase change energy storage interlayer, then pour ultra-high performance concrete into the mold. The ultra-high performance concrete fills the space between the mold and the phase change energy storage paraffin to form a concrete encapsulation cavity. Start the vibrating table to vibrate for 10s to 15s, smooth the surface to form the upper cover plate, let it stand indoors for 1 day, then demold, and cure at room temperature and humidity for 14d to 28d or at 90℃ for 24h to 48h.

[0112] like Figure 1 The installation process of the straw treatment irrigation device is shown below:

[0113] After the irrigation ditch is excavated and repaired, the irrigation mechanism 100 is placed in the irrigation ditch, and adjacent irrigation mechanisms 100 are spliced ​​together as one unit through the concave and convex interface ends of the water channel.

[0114] The rotating shaft 522 of the hydraulic crushing mechanism 500 is passed through the outlet hole 217. A power assembly 530 composed of blades is welded to the lower end of the rotating shaft 522. A bearing 521 is fitted onto the upper end of the rotating shaft 522. One end of the connecting rod 512 is welded to the mounting ring seat 510, and the other end is welded to the bearing 521. The blade 523 is welded to the uppermost part of the rotating shaft 522. The filter assembly 540 is welded to the mounting ring seat 510. Bolts are passed through the connecting hole 511 on the mounting ring seat 510 and fixed to the bottom of the straw processing mechanism 200.

[0115] Place the straw processing mechanism 200 on the irrigation mechanism 100, attach the sponge 222 to the outer surface of the partition 221, and install the end plate 215 at the end; put the nutrient material and earthworm mixture 230 into the spaces on both sides of the straw processing mechanism 200; put the straw and microbial degradation material mixture 240 into the middle space of the straw processing mechanism 200; and connect adjacent straw processing mechanisms 200 together through the concave and convex interface ends 214 at the ends.

[0116] Place the waste gas treatment unit 300 on top of the straw treatment unit 200, place the non-woven bag-packaged carbon dioxide curing agent 304 in the space on one side of the movable side plate 305, and fill the remaining space with catalytic oxidant 303.

[0117] Place the lighting assembly 400 on the straw processing mechanism 200, and connect the solar panel 431, controller 433, battery 434, and light source 420 together with wires. Figure 13 As shown, the irrigation mechanism 100, the straw processing mechanism 200, the exhaust gas processing mechanism 300, and the light source mounting glass box 510 of the lighting component 400 are connected together with L-shaped fasteners 600 and fastener bolts, and the straw processing irrigation device is installed.

[0118] The working process of the straw treatment irrigation device:

[0119] Earthworms digest the straw through the through-hole 216, while microorganisms degrade the straw. The resulting mixture of humus and earthworm castings 250 passes through the filter assembly 540. After being finely chopped by the blade 523, the humus and earthworm castings flow into the irrigation mechanism 100 through the outlet 217 and are flushed into the farmland by irrigation water, becoming fertilizer for crops. The waste gas generated from straw degradation enters the waste gas treatment mechanism 300 through the bottom vent 309 and passes through the vents 306 at the ends of each transparent partition 3012. Under the irradiation of sunlight and the light source 420 of the irradiation assembly 400, it is converted into carbon dioxide and water. The carbon dioxide is solidified by the carbon dioxide solidifying agent 304 in the non-woven bag to produce potassium bicarbonate. The movable side plate 305 is opened periodically to replace the carbon dioxide solidifying agent 304 in the non-woven bag, and the potassium bicarbonate is taken out and sprinkled into the farmland as fertilizer. When excess gas accumulates and reaches a certain pressure, the gas pressure relief valve releases the gas.

[0120] The present invention allows crop straw to degrade on irrigation canals, without occupying arable land or requiring long-distance transportation. The degraded humus is washed into the farmland with irrigation water, serving as crop fertilizer.

[0121] This invention uses a combination of microorganisms and earthworms to degrade straw, which is non-toxic, harmless, and does not cause environmental pollution;

[0122] This invention uses phase change energy storage paraffin and sponge to ensure that the internal temperature and humidity of the straw treatment device are suitable for the continuous reproduction and growth of earthworms, thereby improving the efficiency of straw degradation. In addition, the earthworm castings and humus produced by the earthworms digesting the straw are flushed into the farmland with irrigation water, forming fertilizer for crops.

[0123] The mesh cover on the hydraulic pulverizer of this invention can prevent undegraded straw from flowing out, and can also drive the blades to rotate and finely chop humus and earthworm castings by irrigation water, which is conducive to their uniform dispersion in irrigation water and absorption by crops, thereby improving utilization rate.

[0124] This invention converts a small amount of methane waste gas generated from straw degradation into water and carbon dioxide gases through a catalytic oxidant under ultraviolet light and sunlight. At the same time, the gas is solidified by potassium carbonate to produce potassium bicarbonate, which is then used as fertilizer for crops and applied to the fields to support crop growth. The entire process reduces carbon emissions, and the combined irradiation of ultraviolet light and sunlight can meet the catalytic oxidation of waste gas for 24 hours.

[0125] This invention uses a gas pressure relief valve to allow waste gas to pass through the waste gas treatment device under certain resistance, thereby extending the catalytic oxidation time of the waste gas in the device and improving the degree of catalytic oxidation.

[0126] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Furthermore, the contents not described in detail in this specification are all prior art known to those skilled in the art.
