Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to a quantitative fertilizer application device with mixing and stirring function. Background Technology

[0002] With the development of agricultural modernization, large-scale agricultural planting has placed higher demands on fertilization efficiency and precision. Traditional manual fertilization methods are not only labor-intensive and inefficient, but also struggle to ensure the uniformity and accuracy of fertilizer application, easily leading to fertilizer waste and environmental pollution. Therefore, an automatic fertilization device is needed to improve fertilization efficiency and quality, meeting the needs of modern agricultural production.

[0003] Patent publication number CN221979525U discloses a mechanical fertilizer feeding device, including a cylindrical feeding body and a fertilizer box. The fertilizer box is fixed to one side of the cylindrical feeding body, and a bracket is fixed to the top of the fertilizer box. A motor is fixed on the bracket, and the motor drives a rotating shaft that passes into the fertilizer box. A stirring rod is fixed to the outside of the rotating shaft.

[0004] To address the time-consuming and labor-intensive nature of manual application, existing technology employs a motor-driven rotating shaft and a belt-driven input shaft. The rotating shaft, in turn, drives a stirring rod to loosen and agitate the fertilizer in the fertilizer bin, facilitating its dispensing. The bottom of the rotating shaft drives a spiral auger to transport the fertilizer to a guide pipe. The fertilizer then enters the discharge port of a cylindrical feeder and is discharged. A gearbox accelerates the output shaft, which in turn drives a drill bit to create holes. This method allows the fertilizer to enter the drilled holes, reducing fertilizer loss. However, it still suffers from difficulty in precisely controlling the dispensing process, leading to poor adaptability. Utility Model Content

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] 1. This utility model provides a quantitative fertilizer applicator with mixing and stirring function. It employs a left support frame, a motor, a fixed sleeve, a rotating rod, a slot, a locking block, a collection box, a discharge port, a movable sleeve, a chute, a rubber pad, a partition, an adjusting plate, an adjusting rod, a slider, a boss, a connecting rod, a right support frame, a discharge port, a spring, a stop block, a limit block, a movable plate, a turntable, an electric telescopic rod, and a handle. Pushing the handle moves the frame forward. The left support frame fixes the fixed sleeve. When the motor on the surface of the fixed sleeve drives the partition inside the movable sleeve to rotate, the movable sleeve rotates via the rotating rod on the surface of the right support frame. When fertilizer enters the fixed sleeve, the rotating movable sleeve divides the interior of the fixed sleeve into multiple spaces through the partition, achieving quantitative distribution, and finally discharges from the discharge port. When it is necessary to reduce the amount of fertilizer, the electric telescopic rod pushes the boss, causing two sets of sliders to move upwards. The connecting rod connected to these sliders drives the turntable. The rotation causes the remaining connecting rods to move the slider upwards. At this time, the adjusting rod moves upwards along the slide groove, pushing the adjusting plate to move. The two sets of rubber pads fit together to fill the gaps on the surface of the slide groove without affecting the normal displacement of the adjusting rod. When the movable plate on the surface of the adjusting plate contacts the partition, the spring pushes the movable plate to make it fit tightly. The stop block and the limit block cooperate to limit the movable plate. To prevent a small amount of fertilizer from entering the side near the turntable from the slide groove and avoid long-term accumulation that could cause the device to jam, a discharge port is set on the surface of the movable sleeve. When a small amount of fertilizer enters the turntable side, it will fall to the bottom of the movable sleeve. When the movable sleeve rotates and moves the discharge port to the bottom, the fertilizer is discharged from the discharge port and falls into the collection box. When the collection box collects a lot of fertilizer, simply pull the collection box to make the locking block slide out of the locking slot to remove the collection box. The fertilizer in the collection box can still be used, improving the adaptability of the device.

[0018] 2. This utility model provides a quantitative fertilizer feeding device with mixing and stirring function. It adopts the cooperation of a mixing chamber, an upper cover plate, a second motor, a feeding hopper, a first gear, a second gear, a rotating drum, a rotating column, stirring blades, and a rotating shaft. By setting two sets of feeding hoppers, different fertilizers can be injected and stirred at the same time. When the fertilizer enters the mixing chamber, the second motor on the surface of the upper cover plate drives the rotating shaft to rotate, so that the first stirring blade stirs the fertilizer. At the same time, inside the outer shell, the upper bevel gear on the surface of the rotating shaft rotates, which drives the side bevel gear on the surface of the fixed seat to rotate, which in turn drives the lower bevel gear on the surface of the rotating drum to rotate, so that the second stirring blade on the surface of the rotating drum rotates. The first stirring blade and the second stirring blade move in opposite directions on the same axis, making the stirring more disordered, promoting uniform mixing of fertilizer, and improving the adaptability of the device.

[0028] like Figure 1-6As shown, this utility model provides a quantitative feeding and fertilization device with mixing and stirring function, including a frame 1, a handle 4 fixedly installed on the surface of the frame 1, a quantitative feeding mechanism 2 provided on the surface of the frame 1, a mixing and stirring mechanism 3 provided on the surface of the quantitative feeding mechanism 2, the quantitative feeding mechanism 2 including a left support frame 201, the left support frame 201 fixedly installed on the surface of the frame 1, a fixing sleeve 203 fixedly installed on the surface of the left support frame 201, a feeding port 208 fixedly installed at the bottom end of the fixing sleeve 203, a motor 202 fixedly installed on the surface of the fixing sleeve 203, and the motor 202 fixedly installed on the left support frame 201. On the surface of the frame 1, a partition 212 is fixedly installed at the output end of the left support frame 201. A movable sleeve 209 is fixedly installed on the surface of the partition 212. The movable sleeve 209 is movably installed on the surface of the fixed sleeve 203. A discharge port 219 is provided on the surface of the movable sleeve 209. A rotating rod 204 is fixedly installed on the surface of the movable sleeve 209. A right support frame 218 is movably installed on the surface of the rotating rod 204. The right support frame 218 is fixedly installed on the surface of the frame 1. A sliding groove 210 is provided on the surface of the movable sleeve 209. Multiple sets of sliding grooves 210 are evenly distributed on the surface of the movable sleeve 209. The surface of the sliding groove 210 is fixedly installed with... A rubber pad 211 is provided. An adjusting rod 214 is movably mounted on the surface of a slide 210. An adjusting plate 213 is fixedly mounted on the surface of the adjusting rod 214. A limit block 222 is fixedly mounted on the surface of the adjusting plate 213. A spring 220 is fixedly mounted inside the adjusting plate 213. A stop block 221 is fixedly mounted on one end of the spring 220. The stop block 221 is compatible with the limit block 222. A movable plate 223 is fixedly mounted on the surface of the stop block 221. The movable plate 223 is movably mounted inside the adjusting plate 213. A slider 215 is fixedly mounted on one end of the adjusting rod 214. A connecting rod 217 is movably mounted on the surface of the slider 215. One end of the connecting rod 217 is movable. A turntable 224 is movably mounted on the surface of the movable sleeve 209. A boss 216 is fixedly mounted on the surface of the slider 215. Two sets of bosses 216 are provided and are symmetrically distributed on the surface of the slider 215. An electric telescopic rod 225 is fixedly mounted on the surface of the boss 216. The telescopic end of the electric telescopic rod 225 is fixedly mounted on the surface of the boss 216. The quantitative feeding mechanism 2 also includes a slot 205. The slot 205 is fixedly mounted on the bottom end of the frame 1. A block 206 is movably mounted on the surface of the slot 205. A collection box 207 is fixedly mounted on the surface of the block 206. The collection box 207 is adapted to the discharge port 219.

[0029] In this embodiment, the frame 1 is moved forward by pushing the handle 4. The left support frame 201 fixes the fixed sleeve 203. When the motor 202 on the surface of the fixed sleeve 203 drives the partition 212 inside the movable sleeve 209 to rotate, the movable sleeve 209 rotates through the rotating rod 204 on the surface of the right support frame 218. When fertilizer enters the fixed sleeve 203, the rotating movable sleeve 209 divides the interior of the fixed sleeve 203 into multiple spaces through the partition 212, realizing quantitative material distribution, and finally discharges it from the discharge port 208. When it is necessary to reduce the amount of fertilizer, the electric telescopic rod 225 pushes the boss 216, causing the two sets of sliders 215 to move upward. The connecting rod 217 connected to it drives the turntable 224 to rotate, thereby causing the other sets of connecting rods 217 to drive the sliders 215 to move upward together. At this time, the adjusting rod 214 moves upward along the slide groove 210 to push the adjusting plate 213 to move. The two sets of rubber pads 211 stick to each other to make the surface of the slide groove 210... While filling the gap, the normal displacement of the adjusting rod 214 is not affected. When the movable plate 223 on the surface of the adjusting plate 213 contacts the partition plate 212, the spring 220 pushes the movable plate 223 to make it fit tightly. The stop block 221 and the limit block 222 cooperate to limit the movable plate 223. To prevent a small amount of fertilizer from entering the side near the turntable 224 from the chute 210 and avoid long-term accumulation that could cause the device to jam, a discharge port 219 is provided on the surface of the movable sleeve 209. When a small amount of fertilizer enters one side of the turntable 224, it will fall to the bottom of the movable sleeve 209. When the movable sleeve 209 rotates and drives the discharge port 219 to the bottom, the fertilizer will be discharged from the discharge port 219 and fall into the collection box 207. When the collection box 207 collects a lot of fertilizer, simply pull the collection box 207 to make the locking block 206 slide out of the locking groove 205 to take out the collection box 207. The fertilizer in the collection box 207 can still be used, which improves the adaptability of the device.

[0030] Example 2

[0031] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the mixing and stirring mechanism 3 includes a mixing chamber 301, which is fixedly installed on the surface of the fixed sleeve 203. An upper cover plate 302 is fixedly installed on the surface of the mixing chamber 301. A housing 306 is fixedly installed at the bottom end of the upper cover plate 302. A feeding hopper 304 is fixedly installed at the top end of the upper cover plate 302. Two sets of feeding hoppers 304 are provided, and the feeding hoppers 304 are evenly distributed on the surface of the upper cover plate 302. A second motor 303 is fixedly installed at the top end of the upper cover plate 302. A rotating shaft 305 is fixedly installed at the output end of the second motor 303. A stirring blade 310 is fixedly mounted on the surface of a rotating shaft 305. An upper bevel gear 307 is fixedly mounted on the surface of the upper bevel gear 307, and a side bevel gear 309 meshes with the surface of the upper bevel gear 307. A fixed seat 308 is movably mounted on the surface of the side bevel gear 309, and the fixed seat 308 is fixedly mounted inside the housing 306. A rotating drum 312 is movably mounted on the surface of the rotating shaft 305, and the rotating drum 312 is movably mounted on the surface of the housing 306 and extends to the outside of the housing 306. A stirring blade 313 is fixedly mounted on the surface of the rotating drum 312, and a lower bevel gear 311 is movably mounted on the surface of the rotating drum 312, and the lower bevel gear 311 meshes with the surface of the side bevel gear 309.

[0032] In this embodiment, by setting two sets of feed hoppers 304, different fertilizers can be injected and stirred simultaneously. When the fertilizer enters the mixing chamber 301, the motor 303 on the surface of the upper cover plate 302 drives the rotating shaft 305 to rotate, so that the stirring blade 310 stirs the fertilizer. At the same time, inside the outer shell 306, the upper bevel gear 307 on the surface of the rotating shaft 305 rotates, which drives the side bevel gear 309 on the surface of the fixed seat 308 to rotate, which in turn drives the lower bevel gear 311 on the surface of the rotating drum 312 to rotate, so that the stirring blade 313 on the surface of the rotating drum 312 rotates. The stirring blade 310 and the stirring blade 313 move in opposite directions on the same axis, making the stirring more disordered, promoting uniform mixing of fertilizer, and improving the adaptability of the device.

[0033] The working principle of this quantitative feeding and fertilization device with mixing and stirring function will be explained in detail below.

[0034] like Figure 1-6As shown, by setting two sets of feed hoppers 304, different fertilizers can be injected simultaneously for mixing. When the fertilizer enters the mixing chamber 301, the motor 303 on the surface of the upper cover plate 302 drives the rotating shaft 305 to rotate, causing the stirring blades 310 to stir the fertilizer. At the same time, inside the outer shell 306, the upper bevel gear 307 on the surface of the rotating shaft 305 rotates, driving the side bevel gear 309 on the surface of the fixed base 308 to rotate, which in turn drives the lower bevel gear 311 on the surface of the rotating drum 312 to rotate, causing the stirring blades 313 on the surface of the rotating drum 312 to rotate. The stirring blades 310 and 313 move coaxially and in opposite directions, making the mixing more disordered and promoting... The fertilizer is mixed evenly. Pushing handle 4 moves the frame 1 forward. The left support frame 201 fixes the fixed sleeve 203. When the motor 202 on the surface of the fixed sleeve 203 drives the partition 212 inside the movable sleeve 209 to rotate, the movable sleeve 209 rotates via the rotating rod 204 on the surface of the right support frame 218. When the fertilizer enters the fixed sleeve 203, the rotating movable sleeve 209 divides the interior of the fixed sleeve 203 into multiple spaces through the partition 212, achieving quantitative distribution, and finally discharges from the discharge port 208. When it is necessary to reduce the amount of fertilizer, the electric telescopic rod 225 pushes the boss 216, causing the two sets of sliders 215 to... The upward displacement causes the connecting rod 217 to rotate the turntable 224, which in turn causes the other connecting rods 217 to move the slider 215 upward as well. At this time, the adjusting rod 214 moves upward along the slide 210, pushing the adjusting plate 213 to move. The two sets of rubber pads 211 fit together to fill the gaps on the surface of the slide 210 without affecting the normal displacement of the adjusting rod 214. When the movable plate 223 on the surface of the adjusting plate 213 contacts the partition plate 212, the spring 220 pushes the movable plate 223 to fit tightly. The stop block 221 and the limit block 222 cooperate to limit the movable plate 223 to prevent a small amount of fertilizer from flowing out of the slide. 210 enters the side near the turntable 224 to avoid long-term accumulation that could cause the device to jam. By setting a discharge port 219 on the surface of the movable sleeve 209, when a small amount of fertilizer enters the turntable 224, it will fall to the bottom of the movable sleeve 209. When the movable sleeve 209 rotates, it causes the discharge port 219 to move to the bottom, and the fertilizer is discharged from the discharge port 219 and falls into the collection box 207. When the collection box 207 collects a lot of fertilizer, simply pull the collection box 207 to make the locking block 206 slide out of the locking groove 205 to take out the collection box 207. The fertilizer in the collection box 207 can still be used, which improves the adaptability of the device.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
