Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and particularly relates to a soil detection device for plant cultivation. Background Art

[0002] Before planting plants, it is first necessary to use a soil detection device to detect the soil for planting, which can help horticulturists, farmers, and plant enthusiasts better understand the properties of the soil, thereby optimizing the plant growth conditions. The detection device usually measures various soil properties, such as pH value, humidity, soil density, etc. The soil detection devices in the prior art need to first take out a certain volume of soil, and then put the soil into the detection device for detection to obtain various data of the soil. However, it usually cannot achieve automatic feeding of the soil, and comprehensively measure the density, hardness, water content, impurity content, acidity and alkalinity, etc. of the soil. At the same time, during the measurement, the soil needs to be preliminarily broken and pulverized to facilitate more accurate measurement of the hardness and pH value of the soil. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: a soil detection device for plant cultivation, including a box body device. The box body device includes a box body. The box body device is used to realize the feeding of the soil. A density device and an acid-base device are arranged on the box body device. The density device includes an electric cylinder, and the electric cylinder is fixedly installed on the box body. The density device is used to detect the density of the soil. The acid-base device includes a water flow plate, and the water flow plate is fixedly installed on the box body. The acid-base device is used to detect the acidity and alkalinity of the soil.

[0004] Further, the box body device includes a feeding frame fixedly installed on the box body. A feeding hopper is fixedly installed on the feeding frame. A trapezoidal seat is fixedly installed on the box body. A soil pushing plate is slidably installed on the box body. An internal thread plate is fixedly installed on the soil pushing plate. A pushing plate is fixedly installed on the soil pushing plate. A pulling plate is fixedly installed on the internal thread plate.

[0005] Further, an earth inlet mechanism is arranged on the pulling plate. The earth inlet mechanism includes a soil loading box fixedly installed on the pulling plate. A roller is rotatably installed on the soil loading box. The roller is installed in a rolling manner with the feeding frame. A rotating plate is rotatably installed on the soil loading box. An upper rotating block is rotatably installed on the soil loading box. A lower rotating block is rotatably installed on the rotating plate. A tension spring is arranged between the lower rotating block and the upper rotating block.

[0006] Put the soil into the feed hopper, and the soil falls into the soil loading box. In the initial state, the rotating plate supports the bottom of the soil loading box. The volume of the soil loading box is fixed, and the volume of the soil put into the soil loading box each time is fixed. When the lead screw rotates to drive the internally threaded plate to move away from the box body, the soil loading box is driven to move through the pulling plate, and the roller rolls in the feed frame. When the rotating plate leaves above the trapezoidal seat, the weight of the soil presses the rotating plate to rotate, and the soil falls onto the weighing machine. The weighing machine weighs the soil to obtain the density of the soil, and the tension spring is stretched. When all the soil has fallen out, the tension spring rebounds to drive the rotating plate to rotate, and the rotating plate closes with the soil loading box. Then the lead screw rotates in reverse to push the soil loading box back under the feed hopper through the pulling plate. At the same time, the internally threaded plate drives the soil pushing plate and the pushing plate to push out the soil that has been weighed on the weighing machine.

[0007] Further, the density device includes a weighing machine fixedly installed on the box body. A lead screw is rotatably installed on the box body. The internally threaded plate forms a threaded drive with the lead screw. A lead screw motor is fixedly installed on the box body. A motor wheel is fixedly installed on the motor shaft of the lead screw motor. A lead screw wheel is fixedly installed on the lead screw. A side drive belt is wound around the lead screw wheel and the motor wheel.

[0008] Further, a hardness mechanism is provided on the box body. The hardness mechanism includes a rotating opening plate rotatably installed on the box body. A weight sensor is arranged on the upper surface of the rotating opening plate. A closing plate spring is arranged between the rotating opening plate and the box body. The top of the electric cylinder is fixedly installed with a hardness detection plate, and a hardness sensor is arranged below the hardness detection plate.

[0009] A crushing mechanism is provided on the box body. The crushing mechanism includes an upper driven wheel, a middle transmission wheel and an upper driving wheel rotatably installed on the box body. A conveyor belt is wound around the upper driven wheel, the middle transmission wheel and the upper driving wheel. A crushing roller is rotatably installed on the box body. A dispersing plate and a dryer are fixedly installed in the box body. An intermediate gear is fixedly installed on the middle transmission wheel. A crushing gear is fixedly installed on the crushing roller. An upper gear is fixedly installed on the upper driving wheel. A short drive belt is wound around the intermediate gear and the upper gear. A long drive belt is wound around the upper gear. The crushing gear meshes with the intermediate gear.

[0010] The lead screw motor drives the motor wheel to rotate, and drives the lead screw wheel and the lead screw to rotate through the side drive belt.

[0011] The push plate pushes the soil on the weighing machine onto the conveyor belt. The long conveyor belt drives the upper gear and the upper driving wheel to rotate, and drives the middle driving wheel and the middle gear to rotate through the short conveyor belt, thereby driving the crushing roller and the crushing gear to rotate. The rotation of the upper driving wheel drives the conveyor belt to convey the soil. The rotation of the crushing roller initially crushes the soil. The initially crushed soil is dispersed by the dispersing plate, and then the soil is dried by the dryer. Subsequently, the soil reaches the rotating opening plate, and the weight sensor on the rotating opening plate measures the weight of the soil to obtain the moisture content of the dehydrated soil. By comparing with the data of the weighing machine, the water content of the soil can be obtained.

[0012] When all the soil has fallen onto the rotating opening plate, the electric cylinder extends, driving the hardness detection plate to descend. When the hardness detection plate contacts the soil, the hardness sensor on the lower surface of the hardness detection plate measures the hardness of the soil. When the electromagnet is within a certain range close to the magnetic pole, the electromagnet will adsorb the magnetic pole. Subsequently, the electric cylinder contracts, driving the magnetic pole to rise through the electromagnet, thereby driving the rotating opening plate to rotate. The closing plate spring is stretched, and the soil on the rotating opening plate is poured onto the entering conveyor belt. When the rotating opening plate rotates to the highest point, the electromagnet continues to rise, and the electromagnet disengages from the magnetic pole. The rotating opening plate resets under the action of the closing plate spring.

[0013] Further, the acid-base device includes an outer driving wheel rotatably installed on the box body, an entering conveyor belt, an upper driving wheel, and an inner driving wheel. There is a water inlet above the water flow plate and a water outlet below it. The outer driving wheel and the lower driving wheel are wound with the entering conveyor belt. A PH detection pool is fixedly installed on the box body. A pulling plate is rotatably installed on the PH detection pool. A PH meter is fixedly installed on the PH detection pool. A pulling spring is arranged between the pulling plate and the internal thread plate. A driving motor is fixedly installed on the PH detection pool. A driving gear is fixedly installed on the motor shaft of the driving motor. An inner driving gear is fixedly installed on the inner driving wheel. A lower docking gear is fixedly installed on the lower driving wheel. An upper docking gear is fixedly installed on the upper driving wheel. The upper docking gear meshes with the lower docking gear. A long conveyor belt is wound around the inner driving gear, the driving gear, and the upper gear.

[0014] Further, a grinding mechanism is arranged on the box body. The grinding mechanism includes a pressing frame slidably installed on the box body. A pressing spring is arranged between the pressing frame and the box body. An active driving wheel is rotatably installed on the pressing frame. An upper squeezing belt is wound around the active driving wheel and the upper driving wheel. A lower squeezing belt is wound around the lower driving wheel and the inner driving wheel.

[0015] Clean water enters above the water flow plate, and the clean water flows slowly. The flowing water will drive the nearby air to flow, so that impurities such as plastics and feathers with lighter texture in the soil are adsorbed on the flowing water of the water flow plate through the water flow. Other soils will not contact the water flow plate and the water flow, and directly fall onto the conveyor belt and flow out from the water outlet below the water flow plate together with the water flow. By drying and collecting the impurities, the garbage content of the soil can be obtained. The driving motor drives the driving gear to rotate, so as to drive the inner driving gear and the inner transmission wheel to rotate through the long conveyor belt, and at the same time drive the upper gear and the upper driving wheel to rotate. The rotation of the inner transmission wheel drives the lower crushing belt to rotate, so as to drive the lower transmission wheel and the lower docking gear to rotate, so as to drive the upper docking gear and the upper transmission wheel to rotate, so as to drive the upper crushing belt to rotate. The compression spring makes the distance between the upper crushing belt and the lower crushing belt a certain value. The soil is crushed by the upper crushing belt and the lower crushing belt. After crushing, the soil reaches the PH detection pool through the space between the lower crushing belt and the upper crushing belt. A certain amount of clean water is contained in the PH detection pool, and the PH value of the soil mixed with the clean water is detected by the PH meter, so as to obtain the PH value of the soil. After the detection is completed, when the inner threaded plate moves away from the box body, the pull-open plate will be pulled to rotate relative to the PH detection pool through the pull spring, and the water in the PH detection pool will be poured out.

[0016] The beneficial effects of the present invention compared with the prior art are as follows: (1) The box device provided by the present invention can realize the automatic feeding of a certain volume of soil.

[0032] Put the soil into the feeding hopper 107, and the soil falls into the soil loading box 108. In the initial state, the rotating plate 111 supports the bottom of the soil loading box 108. The volume of the soil loading box 108 is certain, and the volume of the soil put into the soil loading box 108 each time is certain. When the lead screw 223 rotates to drive the internally threaded plate 102 to move away from the box body 101, the soil loading box 108 is driven by the pulling plate 105, and the roller 109 rolls in the feeding frame 106. When the rotating plate 111 leaves above the trapezoidal seat 114, the weight of the soil presses the rotating plate 111 to rotate, and the soil falls onto the weighing machine 224. The weighing machine 224 weighs the soil, so as to obtain the density of the soil. The tension spring 113 is stretched. When all the soil has fallen out, the tension spring 113 rebounds, driving the rotating plate 111 to rotate. The rotating plate 111 closes with the soil loading box 108. Then the lead screw 223 rotates in reverse to push the soil loading box 108 back under the feeding hopper 107 through the pulling plate 105. At the same time, the internally threaded plate 102 drives the soil pushing plate 103 and the pushing plate 104 to push out the soil that has been weighed on the weighing machine 224.

A motor wheel 220 is fixedly installed on the motor shaft of the lead screw motor 219. A lead screw wheel 222 is fixedly installed on the lead screw 223. A side drive belt 221 is wound around the lead screw wheel 222 and the motor wheel 220.

[0034] As Figures 5 - 7 As shown, a hardness mechanism is provided on the box body 101. The hardness mechanism includes a rotary opening plate 204 rotatably installed on the box body 101. A weight sensor is provided on the upper surface of the rotary opening plate 204. A closing plate spring 205 is provided between the rotary opening plate 204 and the box body 101. A hardness detection plate 202 is fixedly installed at the top of the electric cylinder 201. A hardness sensor is provided below the hardness detection plate 202.

[0035] As Figures 5 - 7 As shown, a crushing mechanism is provided on the box body 101. The crushing mechanism includes a upper driven wheel 210, a middle drive wheel 211 and a upper driving wheel 212 rotatably installed on the box body 101. A conveyor belt 209 is wound around the upper driven wheel 210, the middle drive wheel 211 and the upper driving wheel 212. A crushing roller 213 is rotatably installed on the box body 101.

[0036] The lead screw motor 219 drives the motor wheel 220 to rotate, and drives the lead screw wheel 222 and the lead screw 223 to rotate through the side drive belt 221.

[0037] The push plate 104 pushes the soil on the weighing machine 224 onto the conveyor belt 209. The long drive belt 218 drives the upper gear 217 and the upper driving wheel 212 to rotate, and drives the middle drive wheel 211 and the intermediate gear 215 to rotate through the short drive belt 216, thereby driving the crushing roller 213 and the crushing gear 214 to rotate. The rotation of the upper driving wheel 212 drives the conveyor belt 209 to convey the soil. The rotation of the crushing roller 213 initially crushes the soil. The initially crushed soil is dispersed by the dispersing plate 208, and then the soil is dried by the dryer 207. Subsequently, the soil reaches the rotary opening plate 204, and the weight of the soil is measured by the weight sensor on the rotary opening plate 204 to obtain the water content of the dehydrated soil. By comparing with the data of the weighing machine 224, the water content of the soil can be obtained.

[0038] After all the soil has fallen onto the rotating plate 204, the electric cylinder 201 extends, driving the hardness detection plate 202 to descend. When the hardness detection plate 202 contacts the soil, the hardness of the soil is measured by the hardness sensor on the lower surface of the hardness detection plate 202. When the electromagnet 203 approaches within a certain range of the magnetic pole 206, the electromagnet 203 will adsorb the magnetic pole 206. Subsequently, the electric cylinder 201 contracts, driving the magnetic pole 206 to rise through the electromagnet 203, thereby driving the rotating plate 204 to rotate. The closing plate spring 205 is stretched, and the soil on the rotating plate 204 is poured onto the feeding conveyor belt 303. When the rotating plate 204 rotates to the highest point, the electromagnet 203 continues to rise, and the electromagnet 203 disengages from the magnetic pole 206. The rotating plate 204 resets under the action of the closing plate spring 205.

[0039] As Figures 8 - 10 shown, the acid-base device includes an outer driving wheel 302 rotatably installed on the box body 101, a feeding conveyor belt 303, an upper driving wheel 308, and an inner driving wheel 310. There is a water inlet above the water flow plate 301 and a water outlet below it. The outer driving wheel 302 and the lower driving wheel 309 are wound with the feeding conveyor belt 303. A PH detection pool 304 is fixedly installed on the box body 101. A pulling plate 306 is rotatably installed on the PH detection pool 304. A PH meter 307 is fixedly installed on the PH detection pool 304. A pulling spring 305 is arranged between the pulling plate 306 and the internal thread plate 102.

The inner driving gear 313, the driving gear 312, and the upper gear 217 are wound with a long driving belt 218.

[0040] As Figures 8 - 10 shown, a grinding mechanism is arranged on the box body 101. The grinding mechanism includes a pressing frame 316 slidably installed on the box body 101. A pressing spring 317 is arranged between the pressing frame 316 and the box body 101. A movable driving wheel 318 is rotatably installed on the pressing frame 316. An upper crushing belt 319 is wound around the movable driving wheel 318 and the upper driving wheel 308. A lower crushing belt 320 is wound around the lower driving wheel 309 and the inner driving wheel 310.

[0041] Clean water enters the water flow plate 301 and flows slowly. The flowing water will drive the nearby air to flow, so that the plastic, feathers and other debris with lighter texture in the soil are adsorbed on the flowing water of the water flow plate 301 through the water flow. Other soil will not contact the water flow plate 301 and the water flow, but will directly fall onto the transmission belt 303 and flow out from the water outlet below the water flow plate 301 along with the water flow. The garbage content of the soil can be obtained by drying and collecting the debris. The transmission motor 311 drives the driving gear 312 to rotate, thereby driving the inner driving gear 313 and the inner driving wheel 310 to rotate through the long transmission belt 218, and at the same time drives the upper gear 217 and the upper driving wheel 212 to rotate. The rotation of the inner driving wheel 310 drives the lower crushing belt 320 to rotate, thereby driving the lower transmission wheel 309 and the lower docking gear 314. The upper connecting gear 315 and the upper transmission wheel 308 rotate, thereby driving the upper crushing belt 319 to rotate, and the compression spring 317 makes the distance between the upper crushing belt 319 and the lower crushing belt 320 be a certain value, and the soil is crushed by the upper crushing belt 319 and the lower crushing belt 320. After crushing, the soil passes between the lower crushing belt 320 and the upper crushing belt 319 to reach the PH detection tank 304. The PH detection tank 304 is filled with a certain amount of clean water. The PH value of the soil mixed with clean water is detected by the PH meter 307 to obtain the PH value of the soil. After the detection is completed, when the internal threaded plate 102 moves in the direction away from the box body 101, the pull-open plate 306 will be pulled by the pulling spring 305 to rotate relative to the PH detection tank 304, and the water in the PH detection tank 304 will be poured out.

[0042] The working principle of a soil detection device for plant cultivation disclosed by the present invention is as follows: Soil is put into the feeding hopper 107, and the soil falls into the soil loading box 108. In the initial state, the rotating plate 111 supports the bottom of the soil loading box 108. The volume of the soil loading box 108 is fixed, and the volume of the soil put into the soil loading box 108 each time is fixed. The lead screw motor 219 drives the motor wheel 220 to rotate, and drives the lead screw wheel 222 and the lead screw 223 to rotate through the side transmission belt 221. When the lead screw 223 rotates, it drives the internally threaded plate 102 to move away from the box body 101, drives the soil loading box 108 to move through the pulling plate 105, and the rollers 109 roll in the feeding frame 106. When the rotating plate 111 leaves above the trapezoidal seat 114, the weight of the soil presses the rotating plate 111 to rotate, and the soil falls onto the weighing machine 224. The weighing machine 224 weighs the soil to obtain the density of the soil, and the tension spring 113 is stretched. When all the soil has fallen out, the tension spring 113 rebounds, drives the rotating plate 111 to rotate, and the rotating plate 111 closes with the soil loading box 108. Subsequently, the lead screw 223 rotates in reverse to push the soil loading box 108 back under the feeding hopper 107 through the pulling plate 105. At the same time, the internally threaded plate 102 drives the soil pushing plate 103 and the pushing plate 104 to push out the soil that has been weighed on the weighing machine 224. The pushing plate 104 pushes the soil on the weighing machine 224 onto the conveyor belt 209. The driving motor 311 drives the driving gear 312 to rotate, thereby driving the upper gear 217 and the upper driving wheel 212 to rotate through the long transmission belt 218, and driving the middle transmission wheel 211 and the middle gear 215 to rotate through the short transmission belt 216, thereby driving the crushing roller 213 and the crushing gear 214 to rotate. The upper driving wheel 212 rotates to drive the conveyor belt 209 to convey the soil. The crushing roller 213 rotates to perform preliminary crushing on the soil. The preliminarily crushed soil is dispersed by the dispersing plate 208, and then the soil is dried by the dryer 207. Subsequently, the soil reaches the rotating opening plate 204, and the weight sensor on the rotating opening plate 204 measures the weight of the soil to obtain the moisture content of the dehydrated soil. By comparing with the data of the weighing machine 224, the water content of the soil can be obtained. When all the soil has fallen onto the rotating opening plate 204, the electric cylinder 201 extends to drive the hardness detection plate 202 to descend. When the hardness detection plate 202 contacts the soil, the hardness sensor on the lower surface of the hardness detection plate 202 measures the hardness of the soil. When the electromagnet 203 approaches within a certain range of the magnetic pole 206, the electromagnet 203 will adsorb the magnetic pole 206. Subsequently, the electric cylinder 201 contracts, drives the magnetic pole 206 to rise through the electromagnet 203, thereby driving the rotating opening plate 204 to rotate, and the closing plate spring 205 is stretched. The soil on the rotating opening plate 204 is poured onto the entering conveyor belt 303. When the rotating opening plate 204 rotates to the highest point, the electromagnet 203 continues to rise, and the electromagnet 203 is separated from the magnetic pole 206. The rotating opening plate 204 resets under the action of the closing plate spring 205.Clean water enters above the water flow plate 301, and the clean water flows slowly. The flowing water will drive the air flow nearby, so that sundries such as plastics and feathers with lighter texture in the soil are adsorbed on the flowing water of the water flow plate 301 through the water flow. Other soils will not contact the water flow plate 301 and the water flow, and directly fall onto the conveyor belt 303 and flow out from the water outlet below the water flow plate 301 together with the water flow. By drying and collecting the sundries, the garbage content of the soil can be obtained. The drive motor 311 drives the drive gear 312 to rotate, so as to drive the inner drive gear 313 and the inner drive wheel 310 to rotate through the long drive belt 218. The rotation of the inner drive wheel 310 drives the lower crushing belt 320 to rotate, so as to drive the lower drive wheel 309 and the lower docking gear 314 to rotate, so as to drive the upper docking gear 315 and the upper drive wheel 308 to rotate, so as to drive the upper crushing belt 319 to rotate. The compression spring 317 makes the distance between the upper crushing belt 319 and the lower crushing belt 320 a certain value. The soil is crushed by the upper crushing belt 319 and the lower crushing belt 320. After crushing, the soil reaches the PH detection pool 304 through the lower crushing belt 320 and the upper crushing belt 319. A certain amount of clean water is contained in the PH detection pool 304, and the PH value of the soil mixed with clean water is detected by the PH meter 307, so as to obtain the PH value of the soil. After the detection is completed, when the inner threaded plate 102 moves away from the box body 101, the pull plate 306 will be pulled to rotate relative to the PH detection pool 304 by the pull spring 305, and the water in the PH detection pool 304 will be poured out.
