Description

Technical Field

[0001] This invention belongs to the field of soil pretreatment technology, and in particular relates to a soil sampling and pretreatment device for landscape design. Background Technology

[0002] Soil sampling and analysis are crucial steps in landscape design and construction. The results provide a scientific basis for plant selection, soil improvement, and drainage design. Furthermore, soil samples need to be pretreated before sampling.

[0003] The document CN112179733B discloses a soil sampling pretreatment device for environmental monitoring, comprising an upper shell, which is cylindrical. A first motor is mounted on the upper shell, and the first motor is fixedly connected to the upper surface of the upper wall of the upper shell via two support plates, which are L-shaped. The shaft of the first motor passes through the upper wall of the upper shell and is rotatably connected to it. Two semi-circular baffles are rotatably connected to the inner part of the shaft of the first motor within the upper shell. The radius of the baffles is the same as the inner diameter of the upper shell. A horizontally arranged baffle is positioned below the baffles, connected to the shaft of the first motor. The fixed plate with a fixed connection has a switching mechanism on its upper surface. This invention dries the sample through a heating element and then crushes the sample twice, resulting in higher crushing quality. It also removes impurities such as stones through a filter plate, making the test results more accurate. Furthermore, it removes dust through components such as an electrostatic adsorption mesh, reducing dust pollution to the air and making it more environmentally friendly and reliable. However, in actual processing, soil samples often contain hard impurities such as stones or scrap iron.

The crushing whip, made of flexible material, achieves efficient preliminary crushing of large soil samples while avoiding damage to hard stones mixed in, thus preventing the crushed hard stones from affecting the overall purity of the sample. At the same time, the main shaft drives the conveying auger and grinding roller to revolve through the drive shaft and protective shell.

At the same time, the rotation and revolution of the conveying auger work together to transport the ground sample to the outer periphery, and the qualified soil particles enter the centralized hopper through the connecting pipe, while stone particles are effectively separated, improving the purity of sample processing. The linkage gear drives the counterweight to rotate eccentrically through the rotating shaft and connecting rod. On the one hand, it assists the grinding roller in improving the grinding effect on the soil sample. On the other hand, the vibration of the grinding roller can prevent soil sample from adhering to the outer surface of the grinding roller, avoiding residual material.

[0028] 2. In this invention, by setting up a feeding and reducing component, and through the detachable installation of the mounting groove and the receiving box, the number of receiving boxes can be adjusted, thereby flexibly adapting to different reducing requirements, improving processing efficiency and applicability. At the same time, when the drive device rotates the disc to drive the material box to rotate, the mechanical cooperation between the actuating plate and the connecting rod ensures the precise opening and closing of the sealing flap, realizing the periodic opening and closing of the feeding square tube, so that the sample is evenly distributed to each receiving box, avoiding cross-contamination. The automatic reset function of the return spring ensures that the sealing flap closes in time, maintaining the sealing of the feeding square tube and preventing sample leakage.

A drive motor 301 is fixedly installed on the top of the processing box 2 through the first mounting plate. One end of the main shaft 304 extends to the outside of the processing box 2 and is connected to one end of the output shaft of the drive motor 301.

[0046] The specific implementation method is as follows: By setting up the processing component 3, the drive motor 301 drives the crushing whip 305 to rotate at high speed through the main shaft 304, so that the crushing whip 305 can crush the soil sample. The crushing whip 305, made of flexible material, achieves efficient preliminary crushing of large soil samples, while avoiding damage to hard stones mixed in, thus preventing the crushed hard stones from being mixed into the sample and affecting the overall purity of the sample. At the same time, the main shaft 304 drives the conveying auger 306 and the grinding roller 307 to revolve through the drive shaft and the protective shell 308. With the cooperation of the transmission gear 310 and the fixed gear ring 309, the drive shaft can rotate, thereby driving the grinding roller 307 and the conveying auger 306 to rotate, forming a complex... In the combined motion, the grinding roller 307, in conjunction with the tilting plate 901, performs secondary pulverization of the soil, significantly improving the pulverization efficiency of the soil sample. Simultaneously, the rotation and revolution of the conveying auger 306 work together to transport the ground sample to the outer periphery, and the qualified soil particles enter the centralized hopper 4 through the connecting pipe 302, while stone particles are effectively separated, improving the purity of the sample processing. The linkage gear 316 drives the counterweight 313 to rotate eccentrically through the rotating shaft 315 and the connecting rod 314. On the one hand, this assists the grinding roller 307 in improving the grinding effect on the soil sample; on the other hand, the vibration of the grinding roller 307 can prevent the soil sample from adhering to the outer surface of the grinding roller 307, avoiding residual material.

[0047] The feeding and reducing assembly 6 includes a sealing flap 605. A feeding square tube 7 is connected to the bottom of the centralized hopper 4. The sealing flap 605 is rotatably connected to the bottom of the feeding square tube 7, and the sealing flap 605 is in contact with the bottom of the feeding square tube 7. A fixing plate 606 is connected to one side of the feeding square tube 7. Multiple return springs 607 arranged in a linear array are provided between the fixing plate 606 and the sealing flap 605. The two ends of the return springs 607 are connected to one side of the sealing flap 605 and one side of the fixing plate 606, respectively. A connecting... A round rod 604 is connected to a rotating roller 603 on its outer surface. A drive device 608 is provided at the bottom of the feeding square tube 7. A rotating disc 609 is rotatably connected to the bottom of the drive device 608. The top of the rotating disc 609 has multiple mounting slots 610 arranged in a circumferential array. A receiving box 601 is inserted into the mounting slots 610. The receiving box 601 has a fan-shaped cross-section. A toggle plate 602 is connected to one side of the receiving box 601. The toggle plate 602 can contact the rotating roller 603 during rotation.

[0048] The specific implementation method is as follows: By setting up the feeding and shrinking component 6, and through the detachable installation of the mounting groove 610 and the receiving box 601, the number of receiving boxes 601 can be adjusted, thereby flexibly adapting to different shrinking requirements, improving processing efficiency and applicability. At the same time, when the drive device 608 drives the material box to rotate by rotating the disc 609, the mechanical cooperation between the actuating plate 602 and the connecting rod 604 can ensure the precise opening and closing of the sealing flap 605, realizing the periodic opening and closing of the feeding square tube 7, so that the sample is evenly distributed to each receiving box 601, avoiding cross-contamination. The automatic reset function of the reset spring 607 ensures that the sealing flap 605 closes in time, maintaining the sealing of the feeding square tube 7 and preventing sample leakage. Furthermore, the automatic triggering of the sealing flap 605 can realize the automation of feeding, thereby improving the overall feeding and shrinking efficiency of the device.

[0049] The cleaning and impurity removal assembly 9 includes an outer ring block 905, which is connected to the outer wall of the mounting box 10. Multiple rotating plates 901 arranged in a circular array are rotatably connected to the outer periphery of the outer ring block 905 via a rotating shaft. One side of the rotating plates 901 is in contact with one side of the outer ring block 905, and the multiple rotating plates 901 can form a closed circle by being in contact with each other. One end of the rotating shaft extends into the interior of the mounting box 10 and is connected to a drive gear 906. The bottom of the multiple drive gears 906 is meshed with the same rotating gear disk 907. A protective box 904 is connected to the bottom of the mounting box 10. A support column 903 is connected to the bottom of the protective box 904. The other end of the support column 903 is connected to the top of the centralized hopper 4. A fixed motor 902 is fixedly installed inside the protective box 904 via a second mounting plate. One end of the output shaft of the fixed motor 902 extends into the interior of the mounting box 10 and is connected to the bottom of the rotating gear disk 907.

[0050] The specific implementation method is as follows: By setting up the impurity removal and cleaning component 9, the fixed motor 902 can drive the synchronous opening and closing of multiple flip plates 901 by rotating the gear disk 907 and the drive gear 906, ensuring that the bottom of the processing box 2 can be opened or sealed quickly and accurately. The synchronous movement design of the flip plates 901 avoids the problem of local jamming or poor sealing, ensuring that impurities such as hard stones are discharged smoothly. Through the closing and opening between multiple flip plates 901, the bottom of the processing box 2 can be quickly closed and opened, realizing the rapid discharge and cleaning of hard impurities.

[0051] Working Principle: During operation, the operator starts the drive motor 301 and feeds soil samples into the processing box 2 through the sample feed hopper 1. The drive motor 301 drives the main shaft 304 to rotate, which in turn drives the crushing whip 305 to rotate at high speed, thus performing preliminary crushing of large soil samples. Because the crushing whip 305 is made of flexible material, it only crushes the soil sample and does not affect any hard stones mixed in. The initially crushed soil sample falls onto the tilting plate 901. During this process, the main shaft 304 drives the protective shell 308, which in turn drives the conveying auger 306 and grinding roller 307 to revolve via the drive shaft. Simultaneously, the transmission gear 310, in conjunction with the fixed gear ring 309, drives the drive shaft to rotate, thus driving... The shaft drives the grinding roller 307 and the conveying auger 306 to rotate. The grinding roller 307, in conjunction with the tilting plate 901, refines and crushes the soil sample. The conveying auger 306 moves the ground sample to the outer periphery of the processing box 2, so that after the soil sample is screened by the filter plate 303, the qualified part passes through the filter plate 303 and enters the centralized hopper 4 through the connecting pipe 302, while the stone particles in the sample remain in the processing box 2. During this process, the grinding roller 307 drives the linkage gear 316 to revolve around the connecting gear plate 312 through the rotating shaft 315, causing the linkage gear 316 to rotate. The linkage gear 316 drives the counterweight block 313 to rotate eccentrically through the rotating shaft 315 and the connecting rod 314, thereby generating eccentric vibration and transmitting the vibration to the grinding roller 307.

[0052] After grinding, the soil sample enters the centralized hopper 4 through the connecting pipe 302 and is discharged through the discharge square pipe 7. At this time, the staff installs different numbers of receiving boxes 601 in the installation slot 610 according to the reduction requirements. The number of receiving boxes 601 can be 2, 4, or 8. Then, the staff starts the drive device 608, which drives the rotating disk 609 to rotate. The rotating disk 609 drives the receiving boxes 601 to rotate through the installation slot 610, and the receiving boxes 601 drive the actuating plate 602 to rotate. During the rotation of the actuating plate 602, the rotating roller 603 and the connecting rod 604 can move. The connecting rod 604 drives the sealing flap 605 to flip to one side, so that the discharge square tube 7 opens, allowing the soil sample to fall into the receiving box 601. When the actuating plate 602 separates from the connecting rod 604, the reset spring 607 drives the sealing flap 605 to reset and make the sealing flap 605 re-seal the discharge square tube 7. When multiple receiving boxes 601 rotate, the above process is repeated to achieve the reduction of soil samples.

[0053] After the soil sample processing is completed, the staff starts the fixed motor 902, which drives the rotating gear 907 to rotate. The rotating gear 907 drives the drive gear 906 to rotate, and the drive gear 906 drives multiple flip plates 901 to rotate synchronously. This causes the sealing disc formed by the flip plates 901 to open, opening the bottom of the processing box 2. Hard stones and other impurities previously stored in the processing box 2 can fall out automatically through the opening. After the impurities are cleaned, the fixed motor 902 drives the rotating gear 907 to rotate. The rotating gear 907 drives the flip plates 901 to reset synchronously through the drive gear 906. Furthermore, the fixed motor 902 is a self-locking motor, which can prevent the flip plates 901 from flipping and affecting the sealing of the bottom of the processing box 2.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
