Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery and equipment, and particularly relates to a ridging fertilizing device based on straw returning to the field. Background Art

[0002] Straw returning to the field is a yield-increasing measure for improving soil fertility. Straw returning to the field can increase soil organic matter, improve soil structure, increase soil porosity, enhance the vitality of microorganisms, and promote the development of crop roots, generally increasing yields by 5% - 10%. When carrying out straw returning to the field, a fertilizing device is usually used to crush the straw and then spread it into the soil. However, during the crushing process of the straw, the straw fragments float in the air, affecting the line of sight of the staff and the air quality of the surrounding area, and easily reducing the efficiency of straw returning to the field.

[0003] In the prior art, horizontal spiral cutting blades and spreading spiral slicing are used to cut and crush the straw inside the chopping device. In this way, the addition of strains is lacking, and the straw only reacts with natural strains, resulting in a low reaction rate and reducing the efficiency of straw returning to the field; a storage tank is used to store microbial bacterial fertilizer, and the microbial bacterial fertilizer and straw fragments are output. In this way, when carrying out straw returning to the field for cold-soaked fields, due to the low temperature of the soil in cold-soaked fields, a suitable temperature cannot be provided for the strains, and the reaction rate between the strains and the straw is low, reducing the efficiency of straw returning to the field; an electromagnetic heating device is used to perform electromagnetic induction heating on the stirring straw. In this way, the water sprinkled onto the cold-soaked field is not magnetized and heated by the electromagnetic heating device, which is not conducive to providing a suitable temperature and pH environment for straw returning to the field, reducing the efficiency of straw returning to the field. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawback in the prior art that the water sprinkled onto the cold-soaked field is not magnetized and heated by the electromagnetic heating device, which is not conducive to providing a suitable temperature and pH environment for straw returning to the field and reducing the efficiency of straw returning to the field, and to propose a ridging fertilizing device based on straw returning to the field.

[0010] Preferably, a handle is installed on the vehicle frame, and a moving mechanism is installed at the bottom, and the input end of the moving mechanism is connected to the output end of the driving device.

[0011] Preferably, a replenishing device and a feeding port are communicated with the top of the electromagnetic heating box, and a discharge port is communicated with the bottom. The replenishing device is used to put bacteria into the interior of the electromagnetic heating box.

[0012] Preferably, the stirring rod includes a stirring shaft rotatably connected inside the electromagnetic heating box. A spiral blade and a plurality of cutting rods are fixedly connected to the stirring shaft. The top end of the stirring shaft penetrates through the electromagnetic heating box and is connected to the first transmission belt. The plurality of cutting rods are staggered and distributed in the gaps of the spiral blade.

[0013] Preferably, the sprinkling mechanism includes a stirring tank, a water pump and a water storage tank installed on the vehicle frame. The input end of the water pump is communicated with a return water pipe, and the output end is communicated with the stirring tank. The top end of the circulating water cavity is rotatably communicated with the end of the return water pipe away from the water pump, and the bottom end is rotatably communicated with a water inlet pipe. The end of the water inlet pipe away from the circulating water cavity hermetically penetrates through the electromagnetic heating box and is communicated with the bottom of the water storage tank. The top of the stirring tank is communicated with a feeding machine, and the bottom is communicated with a water outlet pipe. The feeding machine is used to put quicklime into the interior of the stirring tank. The end of the water outlet pipe away from the stirring tank is communicated with a plurality of nozzles.

[0014] Preferably, the circulating water cavity is spiral and coaxially arranged inside the spiral blade.

[0015] Preferably, a stirrer is installed inside the stirring tank, and the stirrer is used to stir the interior of the stirring tank.

[0016] Preferably, it further includes a dispersing assembly. The dispersing assembly includes a rolling frame rotatably connected to the vehicle frame. The rolling frame is located below the discharge port, and spiral blade rods are coaxially fixedly connected to both sides.

[0018] Preferably, the pressing head is conical, and the plurality of insertion plates and the plurality of pressing heads are staggered.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0020] 1. By setting an electromagnetic heating mechanism, the straw in the electromagnetic heating box is heated, providing a suitable temperature for the strains for straw treatment. Compared with treating straw by strains in cold immersion fields with lower temperatures, the reaction rate between the strains and the straw is significantly increased, and the effect of straw returning to the field is improved. By setting a stirring rod, the driving force of the driving device is used to drive the stirring rod to rotate, stirring and crushing the straw in the electromagnetic heating box. The crushed straw is more likely to react fully with the strains. At the same time, the stirring rod drives the water in the circulating water cavity to rotate, causing the water flow to cut the magnetic induction lines of the electromagnetic heating mechanism, generating magnetized water. By setting a sprinkling mechanism, the magnetized water and lime are mixed quickly to produce high-temperature lime water, which is sprayed onto the cold immersion fields, increasing the soil temperature, facilitating subsequent straw returning to the field reactions, and neutralizing the soil acidity, providing better soil pH conditions for straw returning to the field.

[0021] 2. By setting a spiral circulating water cavity on the stirring rod, under the driving of the water pump and the rotation of the stirring rod, the water inside the circulating water cavity moves spirally upward while rotating, thus continuously cutting the magnetic induction lines of the electromagnetic heating mechanism. The spiral circulating water cavity also extends the water flow path, increases the water flow time, and further extends the magnetization time of the water by the electromagnetic heating mechanism, facilitating the generation of magnetized water.

[0022] 3. By setting a dispersing component, the mixture of straw and strains discharged from the discharge port is evenly dispersed onto the soil; by using a plowing device for plowing work, the soil and straw are fully mixed; by setting a pressing mechanism, the soil mixed with straw is inserted deeper into the soil. Since the soil just treated by the plowing device is relatively loose, pushing the soil mixed with straw to a deeper position in the soil can effectively enhance the soil fertility.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0031] Referring to Figures 1 - 3 and Figure 5 , a ridge tillage fertilization device based on straw returning to the field includes a vehicle frame 18, a driving device 4 is installed on the vehicle frame 18, and further includes those installed on the vehicle frame 18:

[0032] The driving device 4 adopts the prior art and is used to provide power.

[0033] A handle 1 is installed on the vehicle frame 18, and a moving mechanism is installed at the bottom. The input end of the moving mechanism is connected to the output end of the driving device 4.

[0034] The moving mechanism adopts the prior art. When the driving device 4 works, it provides power for the moving mechanism, enabling the device to travel in the field.

[0035] An electromagnetic heating box 9, an electromagnetic heating mechanism is installed inside the side wall of the electromagnetic heating box 9, a stirring rod 14 is rotatably connected inside the electromagnetic heating box 9, the top end of the stirring rod 14 penetrates through the electromagnetic heating box 9, and the same first transmission belt 13 is sleeved between the top end and the output end of the driving device 4.

[0036] The top of the electromagnetic heating box 9 is communicated with a supplementary device 10 and a feeding port 11, and the bottom is communicated with a discharging port 12. The supplementary device 10 is used to put bacteria into the interior of the electromagnetic heating box 9.

[0037] The electromagnetic heating mechanism adopts the existing technology and converts electrical energy into heat energy by using the principle of electromagnetic induction. Part of the box body of the electromagnetic heating box 9 and the stirring rod 14 inside it are made of metal materials. In cooperation with the electromagnetic heating mechanism, heat is transferred to the straw in the box to achieve heating of the straw.

[0038] The stirring rod 14 includes a stirring shaft rotatably connected inside the electromagnetic heating box 9. A spiral blade and a plurality of cutting rods are fixedly connected to the stirring shaft. The top end of the stirring shaft penetrates through the electromagnetic heating box 9 and is connected to the first transmission belt 13. The plurality of cutting rods are staggered and distributed in the gaps of the spiral blade.

[0039] When the stirring shaft rotates, it drives the spiral blade and the cutting rods to rotate, stirring and crushing the straw in the electromagnetic heating box 9.

[0040] A circulating water cavity 15 is formed inside the stirring rod 14. The circulating water cavity 15 is spiral and coaxially arranged inside the spiral blade.

[0041] The sprinkling mechanism, the circulating water cavity 15 forms part of the water inlet pipeline of the sprinkling mechanism, and the water outlet end of the sprinkling mechanism is communicated with a plurality of nozzles 7.

[0042] The sprinkling mechanism includes a stirring tank 2, a water pump 8 and a water storage tank 17 installed on the vehicle frame 18. The input end of the water pump 8 is communicated with a return pipe 6, and the output end is communicated with the stirring tank 2. The top end of the circulating water cavity 15 is rotatably communicated with one end of the return pipe 6 far away from the water pump 8, and the bottom end is rotatably communicated with a water inlet pipe 16.

[0043] Rotary joints are arranged at both ends of the circulating water cavity 15 for rotatably communicating with the return pipe 6 and the water inlet pipe 16.

[0044] One end of the water inlet pipe 16 far away from the circulating water cavity 15 penetrates through the electromagnetic heating box 9 in a sealed manner and is communicated with the bottom of the water storage tank 17. The top of the stirring tank 2 is communicated with a feeding machine 3, and the bottom is communicated with a water outlet pipe 5. The feeding machine 3 is used to put quicklime into the inside of the stirring tank 2, and one end of the water outlet pipe 5 far away from the stirring tank 2 is communicated with a plurality of nozzles 7.

[0045] A stirrer is installed inside the stirring tank 2, and the stirrer is used to stir the inside of the stirring tank 2.

[0046] The stirrer adopts the existing technology and drives the stirring part to rotate through a driving device to stir the inside of the stirring tank 2, improving the mixing effect of the magnetized water and quicklime.

[0047] The plowing device 21, the input end of the plowing device 21 is connected to the output end of the driving device 4, and the plowing device 21 is located on one side of the electromagnetic heating box 9 away from the plurality of nozzles 7.

[0048] The plowing device 21 adopts the prior art. During the driving process of the device, the plowing device 21 is driven by the driving device 4, and its output end continuously tills the soil, facilitating the mixing of straw and soil.

[0049] Referring to Figure 4 , it further includes a dispersing component. The dispersing component includes a rolling frame 20 rotatably connected to the vehicle frame 18. The rolling frame 20 is located below the discharge port 12, and auger leaf rods 19 are coaxially and fixedly connected to both sides. The conveying directions of the two auger leaf rods 19 are both away from the rolling frame 20.

[0050] The rolling frame 20 abuts against the soil and rotates continuously as the device travels, thereby driving the two auger leaf rods 19 to rotate, pushing the straw located in the middle to both sides after discharging, and improving the uniformity of straw dispersion.

[0051] Referring to Figure 4 and Figure 5 , it further includes a pressing mechanism. The pressing mechanism includes a cam 22 rotatably connected to the vehicle frame 18. A same second transmission belt 23 is sleeved between the driving end of the cam 22 and the driving device 4, and a mounting frame 24 is rotatably connected to the driven end. The mounting frame 24 is slidably connected to the vehicle frame 18, and a plurality of insertion plates 25 and pressing heads 26 are fixedly connected to the bottom.

[0052] The pressing head 26 is conical, and the plurality of insertion plates 25 and the plurality of pressing heads 26 are staggered.

[0053] When the present invention is in use, the driving device 4 operates, and its output end drives the moving mechanism to work, enabling the device to travel in the cold-soaked field. The staff controls the traveling direction of the device through the handle 1.

[0054] Start the water pump 8. The input end of the water pump 8 pumps water from the water storage tank 17 through the return water pipe 6, the circulating water chamber 15, and the water inlet pipe 16, and the output end sprays water into the field through the stirring tank 2, the water outlet pipe 5, and a plurality of nozzles 7.

[0055] When the driving device 4 operates, its output end drives the stirring rod 14 to rotate through the first transmission belt 13, adds the preliminarily processed straw into the electromagnetic heating box 9 from the feeding port 11, starts the supplementary device 10, and allows the bacteria to fall into the electromagnetic heating box 9. The stirring rod 14 rotates to break the preliminarily processed straw, enabling the finely crushed straw to react with the bacteria, and improving the fertilizer effect after straw returning to the field.

[0056] The electromagnetic heating mechanism inside the side wall of the electromagnetic heating box 9 operates to heat the interior of the box, appropriately heating the temperature of the straw inside the box to 30 - 40 °C. Since the optimal growth temperatures of most exogenous microbial agents such as cellulolytic bacteria and Trichoderma are 25 - 35 °C, and the soil temperature of cold-waterlogged paddy fields is often lower than 15 °C, by heating the interior of the box, the colonization efficiency of the microbial agent and the enzyme activity can be significantly improved. Secondly, the increase in temperature can shorten the lag period of straw decomposition, promote the rapid reproduction of microorganisms and the secretion of extracellular enzymes, and release nutrients in advance.

[0057] When water passes through the inside of the spiral-shaped circulating water chamber 15 driven by the water pump 8, the spiral-shaped circulating water chamber 15 rotates simultaneously with the stirring rod 14, causing the water inside the circulating water chamber 15 to move spirally upward while rotating, thereby continuously cutting the magnetic induction lines of the electromagnetic heating mechanism. The spiral-shaped circulating water chamber 15 also extends the flow path of the water, increases the water flow time, and further extends the magnetization time of the electromagnetic heating mechanism for the water. Finally, the formed magnetized water enters the inside of the stirring tank 2 driven by the water pump 8.

[0058] When the magnetized water enters the inside of the stirring tank 2, the feeder 3 is started to put quicklime into the magnetized water. The stirrer inside the stirring tank 2 operates to stir and mix the magnetized water and quicklime. Quicklime reacts with water to generate a large amount of heat, producing high-temperature lime water. Since the magnetized water has strong activity and is more likely to react with other substances, the magnetized water can accelerate the reaction rate of quicklime and water, releasing more heat in a short period. The surface tension of the magnetized water is lower, making it easier to penetrate soil particles and straw fibers during subsequent spraying, promoting the diffusion of reaction substances. The magnetized water may also enhance the migration ability of calcium ions in the lime water, accelerating the neutralization of soil acidity.

[0059] The lime water generated inside the stirring tank 2 enters the inside of multiple nozzles 7 through the water outlet pipe 5 and is sprayed onto the cold-waterlogged paddy field through the multiple nozzles 7. Since the soil temperature of the cold-waterlogged paddy field is too low, which has an adverse effect on straw returning to the field, spraying the high-temperature lime water onto the soil surface first can increase the soil temperature, facilitating the subsequent reaction of straw returning to the field. Moreover, the lime water can neutralize the acidity of the soil, providing better soil pH conditions for straw returning to the field.

[0060] The treated straw is discharged from the discharge port 12. When the device is moving, the rolling frame 20 comes into contact with the soil and rotates, driving the auger blade rod 19 thereon to rotate, pushing the straw to both sides, and evenly dispersing the straw to avoid straw accumulation in the middle.

[0061] Subsequently, the plowing device 21 performs plowing work driven by the driving device 4, fully mixing the soil and the straw.

[0062] Finally, the driving device 4 drives the cam 22 to rotate through the second transmission belt 23. The rotation of the cam 22 causes the mounting bracket 24 to reciprocate up and down on the vehicle frame 18. The pressing head 26 and the insertion plate 25 below the mounting bracket 24 continuously insert into and pull out of the soil. The pressing head 26 and the insertion plate 25 cooperate with each other to facilitate the insertion of the soil mixed with straw into the deeper soil. Since the soil just treated by the plowing device 21 is relatively loose, pushing the soil mixed with straw into a deeper position in the soil can effectively enhance the fertility of the soil.

[0063] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
