Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a soil component content detection and control device. Background Art

[0002] Soil testing is one of the important technologies in the agricultural field. It can help farmers understand the content of different nutrients in the soil, thereby guiding them to carry out reasonable fertilization and planting management. Therefore, soil component content detection devices are crucial in agriculture. They are scientific instruments used to quickly and accurately determine the content of various elements in the soil, which can help farmers better manage the soil and improve the yield and quality of crops. Soil component content detection devices usually use spectral analysis, chemical analysis and other technologies to quickly determine the content of key elements such as nitrogen, phosphorus, and potassium in the soil, and give reasonable fertilization recommendations based on the measurement results to avoid problems such as soil barrenness or pollution caused by insufficient or excessive fertilization.

[0003] A soil component detection device is disclosed in a Chinese utility model patent with publication number CN216410828U, which includes a crushing box and a detection box fixed on the lower side of the crushing box. A first crushing rod is rotatably arranged at the center of the bottom of the crushing box, a first crushing gear is fixed at the bottom of the first crushing rod, two second crushing rods are arranged on both sides of the first crushing rod, the second crushing gear at the bottom end of the second crushing rod is meshed with the first crushing gear, and a crushing motor at the bottom end of the first crushing rod drives the first crushing knife on the first crushing rod to cut the soil, and at the same time, the first crushing gear drives the second crushing gear to rotate, so that the second crushing rod rotates by itself and rotates around the first crushing rod under the action of the outer inner gear, so that the second crushing knife intersects with the first crushing knife in all directions to cut the soil.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the above-mentioned device crushes the soil, it cannot remove the stones in the soil. When the soil and stones enter the detection box together, they may get stuck in the feed port of the detection box, causing blockage; and when the detection box is detecting, the stones will affect the detection results, causing inaccurate soil detection.

A crushing tank is arranged on the support base. One side of the top of the crushing tank is provided with a feed hopper. The bottom of the crushing tank is funnel-shaped and is provided with a discharge port. A receiving tray is arranged on the support base at the position of the discharge port. A circular sieve plate with an outer diameter consistent with the inner diameter of the crushing tank is arranged inside the crushing tank. A crushing mechanism is arranged above the circular sieve plate inside the crushing tank. A support frame is arranged on the support base, and a driving mechanism for driving the crushing mechanism to move is arranged on the support frame. An inclined groove extending obliquely downward is opened on the tank wall of the crushing tank below the circular sieve plate. A filter plate with an inclination angle consistent with that of the inclined groove is arranged inside the inclined groove. A vibration mechanism for driving the filter plate to vibrate is arranged at the bottom of the filter plate. One end of the filter plate is located inside the crushing tank and the other end is located outside the crushing tank.

[0007] By adopting the above technical solutions, the support base, detector, crushing tank, circular sieve plate, crushing mechanism, driving mechanism, inclined groove, filter plate and vibration mechanism are set. The soil is poured into the crushing tank from the feed hopper and accumulates on the circular sieve. The crushing mechanism is driven by the driving mechanism to disperse the soil. The dispersed soil will fall from the circular sieve plate. The larger stones will be blocked by the circular sieve plate and remain on the circular sieve plate. The vibration mechanism is used to drive the filter plate to vibrate. The vibrating filter plate filters the falling soil. The filtered soil reaches the receiving tray from the discharge port. The small stones roll out of the crushing tank from the inclined groove under the action of the vibration mechanism, screening out all the stones. The staff puts the soil in the receiving tray into the test tubes of multiple detectors respectively, adds different detection reagents to each test tube. Different detection reagents will react chemically with different elements in the soil to produce different colors. The test tubes are placed in the detection ports of the detectors for detection, ensuring the accuracy of soil detection.

[0008] Furthermore, the vibration mechanism includes a plurality of fixed plates arranged at intervals on the top of the support base. A first slide rail is vertically arranged on the inner side of the fixed plate.

[0011] By adopting the above technical solution, the second driving motor, the transmission shaft, the cross bar, the first pulley, the sliding rod, the rotating shaft, the second pulley, the rotating rod and the crushing rod are provided. The second driving motor drives the transmission shaft to rotate, drives the cross bar to rotate, and thus drives the rotating shaft, the first pulley, the rotating rod and the crushing rod to rotate around the transmission shaft. Since the sliding rod fixes the first pulley and makes it unable to rotate with the rotating shaft, under the action of the transmission belt, while the rotating shaft, the rotating rod and the crushing rod rotate around the transmission shaft, they also rotate around the rotating shaft to crush the soil.

[0012] Further, a plurality of crushing spikes are circumferentially arranged on the rod body at the lower end of the crushing rod.

[0013] By adopting the above technical solution, a plurality of crushing spikes are circumferentially arranged on the rod body at the lower end of the crushing rod to increase the crushing effect on the soil.

A sliding seat is slidably arranged on the second slide rail through a slider. The second driving motor is vertically arranged on the sliding seat. A third driving motor is horizontally arranged on the support frame. The output shaft of the third driving motor passes through the vertical plate and is provided with a gear at the end. A rack is vertically arranged on the sliding seat. The rack is meshed with the gear.

[0015] By adopting the above technical solution, the vertical plate, the second slide rail, the sliding seat, the third driving motor, the gear and the rack are provided. The third driving motor drives the gear to rotate, drives the rack, the sliding seat and the second driving motor to move upward along the second slide rail, and thus drives the transmission rod and the crushing rod to rise away from the circular sieve plate.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0032] As Figures 1-6As shown in the figure, an embodiment of the present application discloses a device for detecting and controlling soil component content, including a support base 10, a detector 11, a crushing tank 20, a circular sieve plate 23, a crushing mechanism 30, and a filter plate 25. The detector 11 is arranged inside the support base 10, the crushing tank 20 is arranged on the support base 10, a feed hopper 21 is arranged on one side of the top of the crushing tank 20, the bottom of the crushing tank 20 is funnel-shaped and is provided with a discharge port 22, and a receiving tray 12 is arranged on the support base 10 at the position of the discharge port 22. The circular sieve plate 23 is arranged inside the crushing tank 20, and its outer diameter is the same as the inner diameter of the crushing tank 20 to screen the soil, and there is no gap between the circular sieve plate 23 and the crushing tank 20 to prevent uncrushed soil from leaking out. The circular sieve plate 23 includes a bottom plate and a retaining wall extending upward along the edge of the bottom plate. The crushing mechanism 30 is arranged inside the crushing tank 20 above the circular sieve plate 23 to crush the soil on the circular sieve plate 23. An inclined groove 24 extending obliquely downward is formed on the tank wall of the crushing tank 20 below the circular sieve plate 23, the filter plate 25 is arranged in the inclined groove 24 and has the same inclination angle as the inclined groove 24, and a vibration mechanism 50 for driving the filter plate 25 to vibrate is arranged at the bottom of the filter plate 25. By driving the filter plate 25 to vibrate through the vibration mechanism 50, the stones are further screened out. The soil is poured from the feed hopper 21 onto the circular sieve plate 23, the crushing mechanism 30 crushes the soil, the circular sieve plate 23 and the filter plate 25 screen out the stones in the crushed soil, and the staff puts the soil in the receiving tray 12 into the test tubes of multiple detectors 11 respectively, and different detection reagents are added to each test tube. Different detection reagents will react chemically with different elements in the soil to produce different colors. The test tubes are placed into the detection ports of the detectors 11 for detection. The detectors 11 adopt the photoelectric colorimetric method. Based on the color of the solution of the substance to be measured or the colored solution generated after adding a color developing agent, the color depth is proportional to the substance content. Then, according to the intensity of the light absorbed by the colored solution, the content of the substance in the solution can be measured, ensuring the accuracy of soil detection.

[0033] Specifically, a support frame 13 is arranged on the support base 10. A vertical plate 131 is vertically arranged on the support frame 13. Two vertically arranged second slide rails 132 are arranged at intervals on the vertical plate 131. A sliding seat 133 is slidably arranged on the second slide rails 132 through sliders, so that the sliding seat 133 can slide on the second slide rails 132. A third driving motor 134 is horizontally arranged on the support frame 13. The output shaft of the third driving motor 134 passes through the vertical plate 131 and a gear 135 is arranged at the end. A rack 136 is vertically arranged on the sliding seat 133. The rack 136 meshes with the gear 135. By driving the gear 135 to rotate through the third driving motor 134, the rack 136 and the sliding seat 133 are driven to move up and down along the second slide rails 132.

[0034] A driving mechanism 40 for driving the crushing mechanism 30 to move is provided on the sliding seat 133. The driving mechanism 40 includes a second driving motor 41 and a transmission shaft 42. The second driving motor 41 is vertically arranged on the sliding seat 133, the output shaft of the second driving motor 41 faces downward, the transmission shaft 42 is fixedly connected to the end of the output shaft of the second driving motor 41 and is concentrically arranged, so that the second driving motor 41 can drive the transmission shaft 42 to rotate. The crushing mechanism 30 includes a cross bar 31. The lower end of the transmission shaft 42 passes through the crushing tank 20 and is fixedly connected to the cross bar 31. The cross bar 31 is driven to rotate by driving the transmission shaft 42 to rotate by the second driving motor 41. A first belt pulley 32 is rotatably arranged on the rod body of the transmission shaft 42 located inside the crushing tank 20. A sliding hole 33 is vertically formed in the first belt pulley 32. A sliding rod 34 is arranged inward at the top of the crushing tank 20. The sliding rod 34 is slidably connected to the sliding hole 33, so that when the transmission shaft 42 rotates, the first belt pulley 32 will not rotate with the transmission shaft 42. And the distance from the lower end of the sliding rod 34 to the top surface of the cross bar is greater than the rising distance of the driving mechanism 40, so as to prevent the driving mechanism 40 and the crushing mechanism 30 from rising and causing interference between the sliding rod 34 and the cross bar 31. A rotating shaft 35 is vertically rotatably arranged at one end of the cross bar 31 away from the transmission shaft 42. A second belt pulley 36 is arranged at the upper end of the rotating shaft 35. The first belt pulley 32 and the second belt pulley 36 are connected by a transmission belt 37. By driving the transmission shaft 42 to rotate by the second driving motor 41, the cross bar 31 is driven to rotate, thereby driving the rotating shaft 35 to rotate around the transmission shaft 42. Since the sliding rod 34 fixes the first belt pulley 32 and makes it unable to rotate with the rotating shaft 35, under the action of the transmission belt 37, while the rotating shaft 35 rotates around the transmission shaft 42, it also rotates self - rotatably. A rotating rod 38 is arranged at the lower end of the rotating shaft 35. A plurality of crushing rods 39 are arranged at intervals at the bottom of the rotating rod 38. The bottom of the crushing rods 39 is arranged adjacent to the top of the circular sieve plate 23. The rotating shaft 35 rotates around the transmission shaft 42 and rotates self - rotatably at the same time, driving the rotating rod 38 and the crushing rods 39 to rotate around the transmission shaft 42 and rotate self - rotatably at the same time to crush the soil. A plurality of crushing thorns 391 are circumferentially arranged on the rod body at the lower end of the crushing rod 39 to enhance the crushing effect on the soil.

[0035] Filter holes are provided on the plate body of the filter plate 25 located inside the crushing tank 20 to filter the crushed soil. A vibration mechanism 50 for driving the vibration of the filter plate 25 is provided at the bottom of the filter plate 25. The vibration mechanism 50 includes a fixed plate 51, a first slide rail 52, and a first driving motor 54. There are four fixed plates 51 spaced apart on the top of the support base 10. The first slide rail 52 is vertically arranged inside the fixed plate 51. The opposite sides of the plate body of the filter plate 25 located outside the crushing tank 20 are slidably connected to the first slide rail 52 through sliders, so that the filter plate 25 can move up and down along the first slide rail 52. A rocker 53 is hingedly arranged at the bottom of the plate body of the filter plate 25 located outside the crushing tank 20. The first driving motor 54 is horizontally arranged on the top of the support base 10. A crank 55 is arranged on the output shaft of the first driving motor 54. One end of the crank 55 away from the output shaft of the first driving motor 54 is hingedly connected to one end of the rocker 53 away from the filter plate 25 through a hinge shaft 56. By driving the rotation of the crank 55 by the first driving motor 54, the rocker 53 is driven to move, so that the filter plate 25 moves up and down along the first slide rail 52.

[0036] When specifically arranged, a horizontal groove 26 is provided on the tank wall of the crushing tank 20. Two parallel horizontal plates 27 are horizontally arranged on the tank walls of the crushing tank 20 on both sides of the horizontal groove 26. A third slide rail 28 is arranged inside the horizontal plate 27. The two sides of the circular sieve plate 23 are respectively slidably connected to the third slide rail 28 through sliders. When the third driving motor 134 drives the sliding seat 133 to rise, driving the crushing mechanism 30 to rise so that the bottom of the crushing rod 39 is higher than the enclosure of the circular sieve plate 23, the circular sieve plate 23 can slide out along the third slide rail 28 to clean the stones inside the circular sieve plate 23. Threaded holes are provided on the circular sieve plate 23, and through holes 29 are correspondingly provided on the horizontal plate 27 and the third slide rail 28. Bolts are used to pass through the through holes 29 and screw into the threaded holes to fix the circular sieve plate 23, which is convenient for disassembly. A handle 231 is arranged on one side of the circular sieve plate 23 located in the horizontal groove 26, which is convenient for pulling out the circular sieve plate 23.

[0037] In this embodiment, the working principle of a device for detecting and controlling soil component content is as follows: Pour the soil into the crushing tank 20 from the feed hopper 21. Start the second driving motor 41 to drive the transmission rod to rotate, driving the cross bar 31, the rotating shaft 35, the first belt pulley 32, the rotating rod 38 and the crushing rod 39 to rotate around the transmission shaft 42. Since the sliding rod 34 fixes the first belt pulley 32, it cannot rotate with the rotating shaft 35. Under the action of the transmission belt 37, while the rotating shaft 35, the rotating rod 38 and the crushing rod 39 rotate around the transmission shaft 42, they also rotate around the rotating shaft 35 to crush the soil. Start the first driving motor 54 to drive the crank 55 to rotate, driving the rocker 53 to move, so that the filter plate 25 vibrates up and down along the first slide rail 52. The crushed soil falls from the circular sieve plate 23 onto the filter plate 25. The stones slide down the inclined filter plate 25 through the chute 24, and the soil passes through the filter plate 25 and reaches the receiving tray 12 through the discharge port 22. The staff puts the soil in the receiving tray 12 into the test tubes of multiple detectors 11 respectively, and adds different detection reagents into each test tube. Different detection reagents will react chemically with different elements in the soil to produce different colors. Put the test tubes into the detection ports of the detectors 11 for detection, ensuring the accuracy of soil detection. When it is necessary to clean the stones in the circular sieve plate 23, start the third driving motor 134 to drive the gear 135 to rotate, driving the driving mechanism 40 and the crushing mechanism 30 to rise. Then screw out the bolts from the threaded holes and the through holes 29, and you can pull the handle 231 to pull out the circular sieve plate 23 to clean the stones in the circular sieve plate 23.

[0038] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
