Description

Technical Field

[0001] This invention relates to the field of fertilization equipment technology, specifically to an experimental multi-nitrogen source fertilizer mixing and application device. Background Technology

[0002] Nitrogen fertilizer refers to a single fertilizer that provides nitrogen nutrition to plants when applied to the soil, with nitrogen as its main component. Nitrogen fertilizers can be classified according to the nitrogen-containing groups into ammoniacal nitrogen fertilizers, ammonium nitrogen fertilizers, nitrate nitrogen fertilizers, ammonium nitrate nitrogen fertilizers, cyanamide nitrogen fertilizers, and amide nitrogen fertilizers. In addition, it also includes fertilizers with other nitrogen sources (such as fermented farmyard manure). Depending on the nitrogen source, the decomposition time of nitrogen fertilizers is different, resulting in different periods of fertilizer effect. Therefore, the mixed application of multiple nitrogen fertilizers will produce better fertilizer effect and longer-lasting fertility.

[0003] When multiple nitrogen sources are applied in combination, they need to be mixed. In experimental planting fields, the nitrogen fertilizer ratio of different nitrogen sources is often studied to produce the best fertilizer effect. It is necessary to frequently change the ratio of various nitrogen sources, the application amount of various mixed nitrogen source fertilizers, and the application conditions of various mixed nitrogen source fertilizers. Then, fertilization is carried out in different experimental plots for comparative verification.

[0004] While mechanical fertilization can be applied as base fertilizer during sowing, large machinery is not convenient to enter the experimental field during the crop growth period because the crop has grown to a certain height. Therefore, a lightweight, labor-saving device that can be easily entered into the experimental field for fertilization is needed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides an experimental multi-nitrogen source fertilizer mixing and application device, the purpose of which is to provide a lightweight, labor-saving device that is convenient to enter the experimental field for fertilization.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] An experimental multi-nitrogen source fertilizer mixing and application device includes a drive mechanism, a travel mechanism, a deep tillage wheel, a mixing mechanism, and a water storage tank;

[0008] The driving mechanism includes a frame, handlebars, front wheel and rear wheel. A mixing mechanism and a water tank are provided on the top of the frame, and a deep tillage wheel is provided on the side of the frame. The mixing mechanism and the water tank are covered by a shell, and the top surface of the shell is connected to a drive mechanism. The drive mechanism drives the driving mechanism to move forward and the deep tillage wheel to rotate.

[0009] The mixing mechanism includes a mixing cylinder and a support wheel. The mixing cylinder rotates during the movement of the traveling mechanism. The support wheel is fixedly connected to the frame. The mixing cylinder is mounted on the support wheel. The mixing cylinder has an array of material troughs and a material receiving trough. The lower end of the material receiving trough is connected to a conveying pipe. The conveying pipe passes through the mixing cylinder and extends downward at an angle towards the handlebars, extending out of the housing between the deep tillage wheel and the rear wheel on the same side.

[0010] The lower end of the water storage tank is connected to a water supply pipe, which passes through the shell and is located between the deep tillage wheel and the rear wheel on the same side.

[0011] This invention utilizes a flatbed cart to carry a mixing mechanism and a water storage tank, enabling the mixing and topdressing of multiple nitrogen fertilizers during the crop growth period, resulting in better fertilizer efficiency and longer-lasting fertility. It is also equipped with a deep tillage wheel to achieve deep tillage and fertilization.

[0012] After adding various nitrogen source fertilizers in different proportions into the mixing drum, the mixing drum rotates as the traveling mechanism moves, simultaneously conveying the fertilizer into the receiving trough and discharging it through the conveying pipe, thus realizing the mixed application of multiple nitrogen source fertilizers.

[0013] During fertilization, the water storage tank provides a small amount of water to the trench to moisten the soil, absorb the ammonia produced by the decomposition of nitrogen fertilizer, and reduce nitrogen fertilizer loss. At the same time, the water storage tank can also be used to apply liquid fertilizers (such as ammonia mixed in water, well-rotted liquid fertilizer, etc.), enabling the mixed application of multi-nitrogen source fertilizers with different properties.

[0014] Furthermore, a fairing is fixedly connected to the frame. The end of the fairing facing the handlebars covers the upper part of the tiller wheel. The height and width of the end of the fairing facing the rear wheel gradually decrease. A through hole for fixing the delivery pipe and water pipe is provided in the middle of the fairing.

[0015] The guide hood can guide the soil turned up by the deep tillage wheel and cover it in the fertilized furrows, achieving automatic soil covering and further reducing fertilizer loss.

[0016] Furthermore, the mixing cylinder is a hollow cylinder with openings at both ends. The end of the mixing cylinder facing the handlebars is lower than the end facing the rear of the vehicle. The outer wall of the mixing cylinder is provided with two annular protrusions for limiting the position of the supported wheel. The opening at the rear of the mixing cylinder is provided with an openable door, and a fixing plate is rotatably connected in the opening at the other end. The fixing plate is provided with an inclined downward hole for the conveying pipe to pass through.

[0017] Furthermore, the material trough is a hollow cuboid with an opening on one side, and the mixing cylinder is provided with an "n"-shaped through hole that matches the cross-section of the material trough. The mixing cylinder is in sliding contact with the material trough, and an adjusting bolt is threadedly connected to the material trough. The rod of the adjusting bolt is rotatably connected to the peripheral wall of the mixing cylinder.

[0018] One end of the feed trough extends into the mixing drum, forming a receiving space with the inner wall of the mixing drum. The feed trough is an adjustable structure, which can adjust the length extending into the mixing drum according to the rotation direction of the adjusting bolt, thereby adjusting the size of the receiving space and achieving different fertilizer application rates.

[0019] Furthermore, a first drive shaft is located below the frame. One end of the first drive shaft is located on the side of the frame and connected to a deep tillage wheel. A driven sprocket is provided in the middle of the first drive shaft. The driven sprocket is connected to the drive mechanism via a chain. A rear wheel axle is connected between the two rear wheels. A helical gear is provided on the rear wheel axle. A square hole corresponding to the helical gear is provided on the frame. A drive ring with inclined teeth is provided outside the mixing cylinder. The upper end of the helical gear passes through the square hole and meshes with the inclined teeth on the drive ring.

[0020] When the rear axle rotates, it drives the mixing drum, enabling simultaneous fertilization while the drum is in motion. Combined with the adjustable feed trough, it allows for adjustments to various fertilization ratios and different fertilization speeds.

[0021] Furthermore, the frame includes a support plate and a tilting plate. The lower surface of the support plate is connected to the first drive shaft at its center. The tilting plate is sleeved outside the first drive shaft and rotatably connected to it. The rear wheel axle is rotatably connected to the tilting plate. The rear wheel axle is connected to the first drive shaft and drives it via a second drive shaft. The free end of the tilting plate is connected to the support plate via a telescopic mechanism. When the telescopic mechanism is retracted to its limit, the lower end of the tillage wheel is lower than the horizontal plane where the lower ends of the rear wheel and the front wheel are located. When the telescopic mechanism is extended to its limit, the helical gear separates from the drive ring, and the lower end of the tillage wheel is higher than the horizontal plane where the lower ends of the rear wheel and the front wheel are located.

[0022] The invention further improves the structure by adding a flip plate, and the second drive shaft and the rear wheel axle are both connected to the flip plate. This allows the invention to stop driving the mixing drum when fertilization is not being carried out (such as on the way to the experimental field or after fertilization). When fertilization is not being carried out, the invention can travel quickly on the road without causing the mixing drum to rotate, thus preventing fertilizer loss. Furthermore, since there is no need to drive the mixing drum to rotate, energy consumption is reduced during travel.

[0023] Furthermore, the first drive shaft is provided with a first bevel gear, and the rear axle is provided with a second bevel gear. The second drive shaft includes a shaft body, a first telescopic core, and a second telescopic core. One end of the shaft body is connected to a third bevel gear, which meshes with the first bevel gear. The other end of the shaft body is provided with a first countersunk hole, in which the first telescopic core is slidably connected. The outer wall of the outer end of the first telescopic core is connected to a fourth bevel gear, and the outer end face is provided with a second countersunk hole, in which the second telescopic core is slidably connected. The free end of the second telescopic core is connected to a worm gear. The shaft body, the first telescopic core, and the second telescopic core are limited by positioning bolts. A worm wheel corresponding to the worm gear is fixedly connected to the rear axle. When the first telescopic core extends out of the first countersunk hole, the fourth bevel gear meshes with the second bevel gear, the second telescopic core retracts into the second countersunk hole, and the worm gear separates from the worm wheel. When the second telescopic core extends out of the second countersunk hole, and the worm gear meshes with the worm wheel, the first telescopic core retracts into the first countersunk hole, and the fourth bevel gear separates from the second bevel gear.

[0024] The special second drive shaft makes the difference between the present invention in terms of travel and fertilization more obvious. When traveling on the road, since there is no need to drive the mixing drum to rotate, the deep tillage wheel does not contact the ground. In addition, the second drive shaft and the rear wheel axle are driven by bevel gears, which can make the invention travel quickly on the road and save energy.

[0025] When fertilizing, a worm gear is used to drive the worm wheel to rotate, which slows down the fertilization speed and improves the accuracy of fertilization. In the field, due to the greater resistance of the soil, it is more difficult to move the device. The worm gear mechanism also has a better transmission effect, making the movement and deep plowing of this invention more stable.

[0026] Furthermore, the water storage tank is high at both ends and low in the middle, with a water filling hole at one end and a round hole corresponding to the water filling hole on the shell.

[0027] The water tank structure, which is high at both ends and low in the middle, makes operation more comfortable for operators.

[0028] Furthermore, the water storage tank has multiple baffles located at the upper part of the middle section of the tank, near the water inlet.

[0029] Multiple baffles ensure that water in the storage tank will not spill out even if there is shaking during the movement of the invention.

[0030] Furthermore, the drive mechanism is provided with a cover, and the drive mechanism includes a storage battery and a drive motor. A miniature water pump is provided on the water supply pipe, and the switch of the miniature water pump is connected to the storage battery via a wire.

[0031] The recessed center of the water tank forms a seat, allowing the operator to sit on the cover of the drive mechanism, further improving ease of operation.

[0032] The beneficial effects of the present invention through the above technical solution are as follows:

[0033] This invention utilizes a flatbed cart to carry a mixing mechanism and a water storage tank, enabling the application of multiple nitrogen fertilizers during the crop growth period, resulting in better fertilizer efficiency and longer-lasting fertility. It is also equipped with a deep tillage wheel for deep tillage and fertilization. The structure is simple and the cost is low, making it particularly suitable for topdressing multiple nitrogen fertilizers during the crop growth period in experimental fields.

[0034] This invention uses a mixing cylinder to mix multiple nitrogen source fertilizers while in motion, and a water storage tank to apply liquid fertilizers. The liquid also moistens the soil, which can reduce fertilizer nitrogen loss and improve fertilizer efficiency.

[0035] The second drive shaft of this invention can switch between the effects of high-speed driving on roads and stable fertilization in fields.

[0036] The invention is a frame structure. The operator sits on the cover of the drive mechanism and can clearly observe the position of the deep tillage wheel and the distance between the crop, making the operation simple and convenient. Attached Figure Description

[0047] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, an experimental multi-nitrogen source fertilizer mixing and application device includes a drive mechanism, a travel mechanism, a deep tillage wheel 1, a mixing mechanism, and a water storage tank 2;

[0049] The driving mechanism includes a frame 3, handlebars 4, a front wheel 5, and a rear wheel 6. The handlebars 4 are rotatably connected to the frame 3, and the front wheel 5 is rotatably connected to the lower end of the handlebars 4. A mixing mechanism and a water tank 2 are provided on the top of the frame 3. There is a gap between the mixing mechanism and the water tank 2. A deep tillage wheel 1 is provided on the side of the frame 3. The deep tillage wheel is a disc. A "V"-shaped or "I"-shaped scraper is provided on the outer ring surface of the deep tillage wheel. The mixing mechanism and the water tank 2 are covered by a shell 7. The shell 7 is open at one end facing the rear of the frame. The top surface of the shell 7 is connected to a drive mechanism. The drive mechanism drives the driving mechanism to move forward and the deep tillage wheel 1 to rotate.

[0050] The mixing mechanism includes a mixing cylinder 8 and support wheels 9. The mixing cylinder 8 rotates during the movement of the traveling mechanism. There are at least four support wheels 9. The support wheels 9 are fixedly connected to the frame 3. The mixing cylinder 8 is mounted on the support wheels 9. The support wheels 9 have an annular groove in the middle for limiting and supporting the mixing cylinder 8. The outer wall of the mixing cylinder 8 has two protrusions 10 for being limited by the support wheels 9. The mixing cylinder 8 has a material trough 11 arrayed inside. The mixing cylinder 8 also has a receiving trough 12 inside. The receiving trough 12 is a hollow quadrangular frustum shape that is larger at the top and smaller at the bottom, with openings at both the top and bottom. The lower end of the receiving trough 12 is connected to a conveying pipe 13. The conveying pipe 13 passes through the mixing cylinder 8 and extends downward at one end towards the handlebars 4, extending out of the housing 7 between the deep tillage wheel 1 and the rear wheel 6 on the same side.

[0051] A water delivery pipe 14 is connected to the lower end of the water storage tank 2, and the water delivery pipe 14 penetrates through the housing 7 and is located between the deep tillage wheel 1 and the rear wheel 6 on the same side.

[0052] As Figure 2 , Figure 3 and Figure 8 shown, a flow deflector 15 is fixedly connected to the frame 3. One end of the flow deflector 15 facing the handlebar 4 covers the upper part of the deep tillage wheel 1. The height and width of one end of the flow deflector 15 facing the rear wheel 6 gradually decrease. A through hole for fixedly connecting the delivery pipe 13 and the water delivery pipe 14 is provided in the middle of the flow deflector 15. The delivery pipe 13 and the water delivery pipe 14 can penetrate into the flow guide groove and be slightly higher than the lower end of the deep tillage wheel, which not only ensures the normal delivery of fertilizer or water, but also avoids the soil thrown out by the deep tillage wheel from washing away the fertilizer or water, ensuring the accurate depth of fertilizer application.

[0053] In this embodiment, deep tillage wheels 1 and flow deflectors 15 of various specifications and models are provided. The scraping plates on the deep tillage wheels 1 of various specifications and models are respectively in a "human" shape or a "one" shape, and the height of the scraping plates increases according to different specifications and models. The distance between the outer end of the scraping plate and the flow deflector 15 increases in sequence to be applicable to different soil properties. For example, for sandy soil, a deep tillage wheel with a "human" shaped scraping plate is used, and the distance between the outer end of the scraping plate and the flow deflector 15 is smaller, which is convenient for the scraping plate to carry as much soil as possible. For muddy soil, a deep tillage wheel with a "one" shaped scraping plate is used. Since muddy soil has high viscosity, the "one" shaped scraping plate is more conducive to scraping the soil adhered to the inner wall of the flow deflector and throwing the soil towards the rear wheel.

[0054] As Figure 3 and Figure 6 shown, the mixing cylinder 8 is a hollow cylinder with openings at both ends. One end of the mixing cylinder 8 facing the handlebar 4 is lower than the end facing the rear of the vehicle. A door 16 that can be opened and closed is provided on the opening at the end of the mixing cylinder 8 facing the rear of the vehicle. A fixing plate 17 is rotatably connected inside the opening at the other end. The fixing plate 17 is fixed to the frame 3 through a connecting plate. An inclined downward hole through which the delivery pipe 13 passes is provided on the fixing plate 17.

[0055] As Figure 6 and Figure 7 shown, the material loading groove 11 is a hollow cuboid with an opening on one side. A "n" shaped through hole corresponding to the cross section of the material loading groove 11 is provided on the mixing cylinder 8. The mixing cylinder 8 is in sliding contact with the material loading groove 11. An adjusting bolt 18 is connected to the material loading groove 11 through a thread. The rod part of the adjusting bolt 18 is rotatably connected to the peripheral wall of the mixing cylinder 8. An adjusting hole corresponding to the material loading groove 11 at the uppermost end of the mixing cylinder 8 is provided on the housing 7. A cover plate is connected to the adjusting hole through a hinge. Opening the cover plate can conveniently adjust the material loading amount of the material loading groove.

[0056] like Figure 2 , Figure 3 and Figure 4 As shown, a first drive shaft 19 is located below the frame 3. One end of the first drive shaft 19 is located on the side of the frame 3 and is connected to a deep tillage wheel 1. A driven sprocket 20 is provided in the middle of the first drive shaft 19. The driven sprocket 20 is connected to the drive mechanism via a chain. A rear wheel axle 21 is connected between the two rear wheels 6. A helical gear 22 is provided on the rear wheel axle 21. A square hole corresponding to the helical gear 22 is provided on the frame 3. A drive ring 23 with inclined teeth is provided outside the mixing cylinder 8. The upper end of the helical gear 22 passes through the square hole and meshes with the inclined teeth on the drive ring 23.

[0057] The frame 3 includes a support plate 24 and a tilting plate 25. The square hole is located on the support plate 24. The lower surface of the support plate 24 is connected to the first drive shaft 19 at its center. The tilting plate 25 is fitted over the first drive shaft 19 and rotatably connected to it. The rear wheel axle 21 is rotatably connected to the tilting plate 25. The rear wheel axle 21 is connected to the first drive shaft 19 via a second drive shaft 26 and drives the vehicle. The free end of the tilting plate 25 is connected to the support plate 24 via a telescopic mechanism 27, which can be a jack or a telescopic motor. Figure 3 As shown, when the telescopic mechanism 27 is retracted to its limit, the lower end of the deep tillage wheel 1 is lower than the horizontal plane where the lower ends of the rear wheel 6 and the front wheel 5 are located. At this time, deep tillage and fertilization can be carried out. Figure 9 As shown, when the telescopic mechanism 27 is extended to its limit, the helical gear 22 separates from the drive ring 23, and the lower end of the deep tillage wheel 1 is higher than the horizontal plane where the lower ends of the rear wheel 6 and the front wheel 5 are located. At this time, the present invention can travel on the road without causing fertilizer loss.

[0058] like Figure 4 and Figure 5As shown, the first drive shaft 19 is equipped with a first bevel gear 28, and the rear axle 21 is equipped with a second bevel gear 29. The second drive shaft 26 includes a shaft body 30, a first telescopic core 31, and a second telescopic core 32. One end of the shaft body 30 is connected to a third bevel gear 33, which meshes with the first bevel gear 28. The other end of the shaft body 30 is provided with a first countersunk hole, in which the first telescopic core 31 is slidably connected. A fourth bevel gear 34 is connected to the outer wall of the outer end of the first telescopic core 31, and a second countersunk hole is provided on its outer end face. Both the second and first countersunk holes are square or other polygonal holes. The second telescopic core 32 is slidably connected in the second countersunk hole. The free end of the second telescopic core 32 is connected to a worm gear 35. The shaft 30, the first telescopic core 31 and the second telescopic core 32 are limited by the positioning bolt 36. Alternatively, positioning pins, positioning beads or other mechanisms with positioning functions can be used. A worm wheel 37 corresponding to the worm gear 35 is fixedly connected to the rear wheel axle 21. When the first telescopic core 31 extends out of the first countersunk hole, the fourth bevel gear 34 meshes with the second bevel gear 29, the second telescopic core 32 retracts into the second countersunk hole, and the worm gear 35 separates from the worm wheel 37. When the second telescopic core 32 extends out of the second countersunk hole and the worm gear 35 meshes with the worm wheel 37, the first telescopic core 31 retracts into the first countersunk hole, and the fourth bevel gear 34 separates from the second bevel gear 29.

[0059] The water storage tank 2 is high at both ends and low in the middle. One end of the water storage tank 2 is provided with a water filling hole 38, and the shell 7 is provided with a round hole corresponding to the water filling hole 38.

[0060] The water storage tank 2 has multiple baffles 39 located at one end near the water inlet 38, which are higher than the upper middle part of the water storage tank 2.

[0061] The drive mechanism is covered by a cover 40. The drive mechanism includes a battery and a drive motor 41. A micro water pump 42 is provided on the water pipe 14. The switch of the micro water pump 42 is connected to the battery via a wire.

[0062] The process of using this invention is as follows: Before use, the experimental field is treated by weeding. Then, fertilizers with multiple nitrogen sources are added to the mixing cylinder of this invention, and liquid fertilizer or water is added to the water storage cylinder for fertilization.

[0063] The working principle of this invention is as follows: The first telescopic core 31 extends out of the first countersunk hole, the fourth bevel gear 34 meshes with the second bevel gear 29, the second telescopic core 32 retracts into the second countersunk hole, and the worm gear 35 separates from the worm wheel 37. At this time, the drive mechanism drives the first transmission shaft 19 to rotate. The first transmission shaft 19 and the second transmission shaft 26 rotate through bevel gear meshing. The second transmission shaft 26 and the rear wheel axle 21 rotate through bevel gear meshing. This invention has a high traveling speed and is suitable for traveling from the preparation area to the field. When reaching the field, the second telescopic core 32 extends out of the second countersunk hole, the worm gear 35 meshes with the worm wheel 37, the first telescopic core 31 retracts into the first countersunk hole, and the fourth bevel gear 34 meshes with the second bevel gear 29. Gear 34 separates from the second bevel gear 29. At this time, the rear wheel axle 21 drives the mixing cylinder 8 to rotate, mixing the fertilizer. The second transmission shaft 26 rotates with the rear wheel axle 21 via a worm gear. This invention has high power and low travel speed, making it suitable for traveling in the soil of the field for deep plowing and fertilization. Furthermore, this invention is equipped with a water storage tank 2. When the liquid stored in the water storage tank 2 is water, the water storage tank 2 moistens the soil during fertilization, which can reduce the loss of nitrogen fertilizer efficiency. When the water storage tank 2 stores liquid fertilizer, this invention can simultaneously apply solid nitrogen fertilizer and liquid nitrogen fertilizer, making it more functional and applicable.

[0064] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made to the technical solutions of the present invention without departing from the spirit of the present invention or the scope of disclosure.
