Description

Technical Field

[0001] The present invention relates to the technical field of stirring, and particularly relates to a medicament stirring device for treating soil heavy metal pollution. Background Art

[0002] Soil heavy metal pollution refers to the excessive content of trace harmful elements in the soil exceeding the background value due to human activities, and the excessive deposition is collectively referred to as soil heavy metal pollution. The heavy metals polluting the soil mainly include elements with significant biological toxicity such as mercury (Hg), cadmium (Cd), lead (Pb), chromium (Cr), and metalloid arsenic (As), as well as elements with certain toxicity such as zinc (Zn), copper (Cu), nickel (Ni), etc. Excessive heavy metals can cause disorders in plant physiological functions and nutritional imbalances. Elements such as cadmium and mercury have relatively high enrichment coefficients in crop seeds. Even if they exceed the food hygiene standards, they do not affect the growth, development, and yield of crops. In addition, mercury and arsenic can weaken and inhibit the activities of nitrifying and ammonifying bacteria in the soil, affecting nitrogen supply. Heavy metal pollutants have very little mobility in the soil, are not easily leached by water, and are not degraded by microorganisms. After entering the human body through the food chain, they pose great potential hazards, and special attention should be paid to preventing heavy metal pollution of the soil.

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application claimed, but merely represents the selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0022] In practice, the inventor found that under the action of the cam of the discharging mechanism, the baffle is periodically opened, so that the medicament in the device sprays the soil, resulting in poor mixing degree of the medicament and soil, and insufficient stirring causes poor uniformity of the medicament.

[0023] Based on the above findings, the present application proposes a medicament stirring device for treating soil heavy metal pollution, which can improve the degree of full mixing of the medicament and soil and the uniformity of the medicament.

[0024] Embodiment 1 Refer to Figures 1 to 8 , the present application discloses a medicament stirring device for treating soil heavy metal pollution, which includes a box body 1, a connecting mechanism 2, a swinging mechanism 3, an earth-digging mechanism 4, a stirring mechanism 5 and a spraying mechanism 6. The connecting mechanism 2 is rotatably arranged in the box body 1. The connecting mechanism 2 drives the swinging mechanism 3 and the earth-digging mechanism 4 in a linkage manner. When the device moves, the connecting mechanism 2 rotates to drive the swinging mechanism 3 and the earth-digging mechanism 4 to operate. A stirring mechanism 5 is arranged behind the box body 1. The spraying mechanism 6 is communicated with the stirring mechanism 5. The spraying mechanism 6 is also arranged on the swinging mechanism 3. After the spraying mechanism 6 sucks the medicament in the stirring mechanism 5, the swinging of the swinging mechanism 3 drives the spraying mechanism 6 to swing left and right to spray the medicament.

[0025] Specifically, the box body 1 is a rectangle with a length of 60 cm, a width of 40 cm and a height of 80 cm. The first partition 101 and the second partition 102 are respectively arranged on the box body 1 from bottom to top. The box body 1 is divided into a bottom box 103, a middle box 104 and a top box 105 by the first partition 101 and the second partition 102. The connecting mechanism 2 and the earth-digging mechanism 4 are arranged in the bottom box 103. The swinging mechanism 3 is communicated and arranged in the bottom box 103 and the middle box 104. The spraying mechanism 6 is arranged in the top box 105. The bottom box 103, the middle box 104 and the top box 105 enable each structure to be distributed orderly, without interfering with each other, reducing the generation of faults, and thus ensuring the more stable operation of the device.

[0026] It should be noted that there are two groups of connecting mechanisms 2, which are arranged front and back at the bottom of the bottom box 103. The connecting mechanism 2 includes a first connecting rod 201, a driving wheel 202 and a roller 203. The driving wheels 202 are symmetrically and fixedly connected to the first connecting rod 201 respectively. The two ends of the first connecting rod 201 are respectively connected to the rollers 203. The rotation of any one of the first connecting rod 201, the driving wheel 202 and the roller 203 will drive the rotation of the other two structures. In the present application, when the device is pushed forward, that is, when the roller 203 rotates, it will drive the first connecting rod 201 and the driving wheel 202 to rotate synchronously, so as to drive the swinging mechanism 3 and the earth-digging mechanism 4 to work. For the automatic operation of the device, a motor can also be connected to the first connecting rod 201, and the motor drives the first connecting rod 201 to rotate, so that the driving wheel 202 and the roller 203 rotate simultaneously. Since the roller 203 rotates, it will drive the whole device to move, so that the device sprays medicine in different polluted areas.

[0027] It should be noted that when the present application is used as an agricultural device, there are two sets of the swing mechanisms 3, which are arranged front and back in the bottom box 103 and the middle box 104 and cooperate with the connecting mechanism 2. The swing mechanism 3 includes a power transmission module, a connecting block 305 and a swing module. The two sets of power transmission modules are symmetrically arranged. One end of the power transmission module cooperates with the driving wheel 202, and the connecting block 305 is fixedly connected above the other end. One end of the connecting block 305 is slidably connected to the swing module. The two sets of swing modules are arranged front and back, providing conditions for sufficient mixing of the medicament and the soil.

[0028] Among them, the power transmission module includes a first driven wheel 301, a second connecting rod 302, a belt pulley 303 and a transmission belt 304. The first driven wheel 301 cooperates with the driving wheel 202. The first driven wheel 301 is connected to one end of the second connecting rod 302. The other end of the second connecting rod 302 is connected to the belt pulley 303. The outer circumference of the belt pulley 303 is connected to the transmission belt 304. The transmission belt 304 is fixedly connected to the connecting block 305 above.

[0029] In addition, the swing module includes a slider 306, a third connecting rod 307, a fourth connecting rod 308, a sliding rod 309, a telescopic rod 310 and a limiting rod 311. Both ends of the slider 306 slide in the limiting rod 311. The slider 306 is slidably connected to the connecting block 305 below and connected to the third connecting rod 307 above. The third connecting rod 307 is rotatably connected to the fourth connecting rod 308. The fourth connecting rod 308 is rotatably connected to the sliding rod 309. The sliding rod 309 slides on the box body 1. The other end of the sliding rod 309 is rotatably connected to the telescopic rod 310. The telescopic rod 310 is rotatably connected to the outer wall of the box body 1. In the present application, when the driving wheel 202 drives the first driven wheel 301 to start rotating, the first driven wheel 301 will drive the belt pulley 303 to rotate synchronously through the second connecting rod 302. The rotation of the belt pulley 303 drives the transmission belt 304 to rotate. The rotation of the transmission belt 304 drives the connecting block 305 to rotate synchronously. Since the connecting block 305 is slidably connected below the slider 306, when the transmission belt 304 rotates to the position of the belt pulley 303, the connecting block 305 slides in the slider 306, causing both ends of the slider 306 to slide linearly back and forth in the limiting rod 311. When the slider 306 slides linearly back and forth, it will drive the third connecting rod 307 to move together. Since the sliding rod 309 can only slide on the box body 1 and the third connecting rod 307 is rotatably connected to the fourth connecting rod 308 and the fourth connecting rod 308 is rotatably connected to the sliding rod 309, when the third connecting rod 307 moves back and forth, the end of the fourth connecting rod 308 rotatably connected to the third connecting rod 307 will approach or move away from the sliding rod 309. When the fourth connecting rod 308 approaches the sliding rod 309, the sliding rod 309 will stretch the telescopic rod 310 and move to the right. When the fourth connecting rod 308 moves away from the sliding rod 309, the sliding rod 309 will first compress the telescopic rod 310 and then stretch the telescopic rod 310 and move to the left, that is, the sliding rod 309 swings left and right.

[0030] It should be added that the soil excavation mechanism 4 includes a first rotating assembly, a second rotating assembly and a soil excavation assembly. The first rotating assembly and the second rotating assembly are sequentially rotatably arranged on the bottom wall of the bottom box 103 from back to front. The tail end of the soil excavation assembly is rotatably connected to the first rotating assembly, and the front of the soil excavation assembly is rotatably connected to the second rotating assembly.

[0031] Secondly, the first rotating assembly includes a fifth connecting rod 401 and a second driven wheel 402. The fifth connecting rod 401 is rotatably arranged on the bottom wall of the bottom box 103, and both ends of the fifth connecting rod 401 are respectively connected to the second driven wheel 402. The second rotating assembly includes a sixth connecting rod 403 and a third driven wheel 404. The sixth connecting rod 403 is rotatably arranged on the bottom wall of the bottom box 103, and both ends of the sixth connecting rod 403 are respectively connected to the third driven wheel 404. The size of the third driven wheel 404 is 3 to 4 times that of the second driven wheel 402.

[0032] Furthermore, the soil excavation assembly includes a seventh connecting rod 405 and soil excavation teeth 406. The tail ends of two seventh connecting rods 405 are rotatably connected above the second driven wheel 402, the front of the seventh connecting rod 405 is rotatably connected below the third driven wheel 404, and soil excavation teeth 406 are evenly arranged at the front end of the seventh connecting rod 405.

[0033] In this application, when the driving wheel 202 starts to rotate, since the second driven wheel 402 and the third driven wheel 404 are engaged with the driving wheel 202, the second driven wheel 402 and the third driven wheel 404 start to rotate, and the size of the third driven wheel 404 is 3 to 4 times that of the second driven wheel 402. When the third driven wheel 404 rotates one circle, the second driven wheel 402 rotates 3 to 4 circles. Therefore, the front of the seventh connecting rod 405 will move up and down relative to the rear, and at the same time, due to the rotation of the second driven wheel 402 and the third driven wheel 404, the seventh connecting rod 405 will move back and forth. By moving the seventh connecting rod 405 upward and forward, the soil excavation teeth 406 will move forward relative to the soil. By moving the seventh connecting rod 405 downward and backward, the soil excavation teeth 406 will move backward relative to the soil, so as to excavate the soil, turn the soil over, and thoroughly treat the soil.

[0034] A usage process of this embodiment is as follows: Push the device forward. The roller 203 rotates to drive the first connecting rod 201 and the driving wheel 202 to rotate synchronously, or start the motor connected to the first connecting rod 201. The motor drives the first connecting rod 201 to rotate, so that the driving wheel 202 and the roller 203 rotate simultaneously, and the device moves forward. The driving wheel 202 rotates to drive the first driven wheel 301 to start rotating. The first driven wheel 301 synchronously drives the pulley 303 to rotate through the second connecting rod 302. The rotation of the pulley 303 drives the transmission belt 304 to rotate. The rotation of the transmission belt 304 drives the connecting block 305 to rotate. When the transmission belt 304 rotates to the pulley 303, the connecting block 305 slides in the slider 306, so that the two ends of the slider 306 slide back and forth in a straight line in the limit rod 311. The sliding of the slider 306 drives the third connecting rod 307 to move. When the third connecting rod 307 moves, the end of the third connecting rod 307 that is rotatably connected to the fourth connecting rod 308 will approach the sliding rod 309 or move away from the sliding rod 309. When the fourth connecting rod 308 approaches the sliding rod 309, the sliding rod 309 will stretch the telescopic rod 310 to move to the right. When the fourth connecting rod 308 moves away from the sliding rod 309, the sliding rod 309 will first compress the telescopic rod 310 and then stretch the telescopic rod 310 to move to the left. The rotation of the driving wheel 202 drives the second driven wheel 402 and the third driven wheel 404 to rotate. Since the size of the third driven wheel 404 is 3 to 4 times that of the second driven wheel 402, when the third driven wheel 404 rotates one circle, the second driven wheel 402 rotates 3 to 4 circles. Therefore, the seventh connecting rod 405 will be lifted and lowered and move forward and backward. That is, when the seventh connecting rod 405 moves upward and forward, the digging teeth 406 will move forward relative to the soil. When the seventh connecting rod 405 moves downward and backward, the digging teeth 406 will move backward relative to the soil, thereby digging the soil. That is to say, the operation of the driving wheel 202 drives the swing mechanism 3 and the digging mechanism 4 to start running. Since the digging mechanism 4 is at the bottom of the box body 1, the device moves from front to back. The first swing mechanism 3 swings left and right in front of the box body 1, and the digging mechanism 4 digs the soil at the bottom of the box body 1. The second swing mechanism 3 swings left and right behind the box body 1.

[0035] Embodiment 2 See also Figures 9 to 10 The present application is an agricultural equipment, wherein the spraying mechanism 6 passes through the box 1 and is connected to the swinging mechanism 3, and the swinging mechanism 3 drives the spraying mechanism 6 to swing left and right to spray the medicine, thereby ensuring that the medicine liquid is fully mixed with the soil.

[0036] Specifically, the drug spraying mechanism 6 includes drug suction modules symmetrically arranged on the inner wall of the pressing wheel 501, and drug delivery modules connected to the two drug suction modules. The drug delivery modules include a first drug delivery module and a second drug delivery module, one drug suction module is connected to the first drug delivery module, and the other drug suction module is connected to the second drug delivery module.

[0037] Among them, the medicine suction module includes a medicine suction tube 601, a gravity ball 602, and a medicine suction pump 603. One end of the medicine suction tube 601 is connected to the gravity ball 602, and the other end is connected to the medicine suction pump 603. The medicine suction pump 603 is arranged on the inner wall of the pressing wheel 501. The gravity ball is located at the end of the medicine suction tube 601 and can move within the pressing wheel 501 to ensure that the medicine suction tube 601 is always below the medicine, thus facilitating the suction of the medicine.

[0038] Secondly, the first medicine delivery module includes a first medicine delivery tube 604 and a first medicine spraying tube 606. One end of the first medicine delivery tube 604 is communicated with the medicine suction module through the medicine suction pump 603. The first medicine delivery tube 604 passes through the rear of the top box 105 and is connected to the telescopic rod 310. One end of the first medicine spraying tube 606 is telescopically arranged within the first medicine delivery tube 604, and the other end of the first medicine delivery tube 604 is connected to the telescopic rod 310.

[0039] In addition, the second medicine delivery module includes a second medicine delivery tube 605 and a second medicine spraying tube 607. One end of the second medicine delivery tube 605 is communicated with another medicine suction module through the medicine suction pump 603. The second medicine delivery tube 605 passes through the front of the top box 105 and is connected to the telescopic rod 310. The second medicine spraying tube 607 is telescopic within the second medicine delivery tube 605, and the end of the second medicine delivery tube 605 is connected to the telescopic rod 310.

[0040] Furthermore, in order to spray the medicine evenly and without missing the soil, nozzles are provided at the ends of the first medicine spraying tube 606 and the second medicine spraying tube 607. The nozzles can be optionally 1812 buried type scattering nozzles, which have a large spraying range and will not miss the un-treated soil.

[0041] A usage process of this embodiment is as follows: Start the medicine suction pump 603. The medicine suction pump 603 sucks the medicine from within the pressing wheel 501 through the gravity ball 602 into the medicine suction tube 601, and the medicine enters the first medicine spraying tube 606 and the second medicine spraying tube 607 respectively from the medicine suction tube 601 through the medicine suction pump 603; When the medicine enters the first medicine spraying tube 606, the medicine will enter the first medicine delivery tube 604 through the first medicine spraying tube 606 and finally flow out from the nozzle.
