Description

Technical Field

[0001] The present invention relates to the field of soil sampling, and specifically to a sorting type soil sampling and collecting device for land improvement. Background Technique

[0002] Land improvement refers to the activity of improving the utilization efficiency of land by rectifying inefficiently utilized, unreasonably utilized, unutilized, and land damaged by production construction activities and natural disasters. Land improvement is an important means to revitalize stock land, strengthen intensive land use, timely supplement cultivated land, and enhance land productivity. In the soil sampling before land improvement by existing equipment, only simple soil excavation is carried out, and there are many sundries irrelevant to soil nutrient components in this way. For example, rotten branches in a small area will affect the component detection of this soil, and too many miscellaneous stone particles in a small area will also affect the rationality of the detection. In order to improve the accuracy of the soil for land improvement, it is necessary to separate the sundries mixed in the soil, and detecting with soil powder monomers can accurately understand the content of various trace elements in the soil, which is convenient for subsequent accurate improvement.

[0003] During the use of existing soil sampling devices, it is necessary for manpower to insert the sampling head into the soil for sampling. In this way, weeds and other impurities in the soil will be mixed into the soil sample during sampling, resulting in abnormal data obtained from the soil sample detection.

Multiple groups of helical teeth 3064 are fixedly connected to the bottom end of the sleeve 3061;

[0039] The screening mechanism 4 includes a dust-proof cover 401, a vibrating plate 402, a vibrating screen 403, a vibrating component 404, a second motor 405, a second rotating shaft 406, a weeding hook 407, a storage box 408, a first pulley set 409, and a collection box 410. The dust-proof cover 401 is fixedly connected to the top end of the base 1. The top end of the base 1 is fixedly connected to the vibrating plate 402 located inside the dust-proof cover 401 through a spring. The top end of the vibrating plate 402 is fixedly connected to the vibrating screen 403. The side wall of the dust-proof cover 401 is fixedly connected to the second motor 405 extending into the dust-proof cover 401. The output end of the second motor 405 is fixedly connected to the vibrating component 404. The vibrating component 404 is simultaneously fixedly connected to the side walls of the vibrating plate 402 and the vibrating screen 403. The vibrating component 404 includes a housing 4041, a connecting shaft 4042, an eccentric wheel 4043, a transfer disk 4044, a tension belt 4045, and a first rotating shaft 4046. The housing 4041 is fixedly connected to the side walls of the vibrating plate 402 and the vibrating screen 403. The inner wall of the housing 4041 is rotatably connected to the first rotating shaft 4046. The outer wall of the first rotating shaft 4046 is fixedly connected to the eccentric wheel 4043. One end of the first rotating shaft 4046 extending outside the housing 4041 is fixedly connected to the transfer disk 4044. One end of multiple groups of tension belts 4045 is fixedly connected to the side wall of the transfer disk 4044. One end of multiple groups of tension belts 4045 is fixedly connected to one end of the first rotating shaft 4046.

[0040] During the operation of the device, the first motor 304 serves as the power source for the sampling mechanism 3, driving the drill bit 306 to rotate and move downward. The drill bit 306 passes through the sampling hole 2 and contacts the ground, continuously rotating and moving downward, thereby filling the soil sample into the interior of the drill bit 306. During this process, the sliding plate 3063 inside the drill bit 306 moves upward, pushing the ejector rod 3062 upward. Then, the first motor 304 rotates in the reverse direction, causing the drill bit 306 to rotate in the reverse direction and move upward. When the drill bit 306 moves to a sufficient height, the first motor 304 is turned off. Then, the two groups of ejector rods 3062 are pushed to make the sliding plate 3063 slide downward, so that the soil sample enters the screening mechanism 4 through the feeding mechanism 5. The second motor 405 drives the vibrating plate 402 and the vibrating screen 403 to vibrate through the vibrating component 404 to screen the soil sample. The soil samples on the vibrating plate 402 and the vibrating screen 403 enter the two groups of collection boxes 410 respectively along with the vibration of the vibrating plate 402 and the vibrating screen 403. During the process of the motor driving the vibrating component 404, the power of the second motor 405 is transmitted to the tension belt 4045 through the connecting shaft 4042 and then transmitted to the first rotating shaft 4046, making the connection between the motor and the first rotating shaft 4046 a flexible connection. Thus, when the vibrating component 404 vibrates, it is not easy to drive the motor to vibrate. Moreover, the vibrating plate 402 is connected to the base 1 through a spring, making it not easy for the vibrating plate 402 to drive the base 1 to vibrate together when vibrating. During the downward movement of the outer shell, it drives the rack to contact the driving gear, thereby pushing the driving gear to rotate. The driving gear drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the reciprocating lead screw 9 to rotate through the transmission shaft, thereby pushing the slider to move. The slider drives the support rod to move, thereby driving the soft brush to brush the vibrating plate and the vibrating screen. When the outer shell moves upward, the rack drives the driving gear to rotate in the reverse direction. At this time, due to the ratchet between the second bevel gear and the transmission shaft, the reciprocating lead screw 9 cannot be driven to rotate. When sampling, the outer shell needs to descend in multiple groups to obtain enough soil samples, thereby driving the reciprocating lead screw 9 to rotate multiple times, making the slider reciprocate to clean the vibrating plate and the vibrating screen.

[0041] Please refer specifically to Figure 7 , the inner wall of the dust cover 401 is rotatably connected to the second rotating shaft 406. The outer wall of the second rotating shaft 406 is fixedly connected with multiple groups of weeding hooks 407. The inner wall of the dust cover 401 is fixedly connected with a storage frame 408 located above the second rotating shaft 406. The side wall of the dust cover 401 is fixedly connected with two groups of collection boxes 410. The other end of the first rotating shaft 4046 is fixedly connected to the output end of the second motor 405. One end of the first pulley group 409 is fixedly connected to the connection part of the first rotating shaft 4046 and the second motor 405, and the other end of the first pulley group 409 is fixedly connected to the outer wall of the second rotating shaft 406. The bottom of the storage frame 408 is provided with multiple groups of slots, and the positions of the slots coincide with the positions of the weeding hooks 407.

[0042] During the rotation of the second motor 405, the second rotating shaft 406 is driven to rotate through the first pulley set 409, so that the weeding hook 407 rotates, thereby hooking the weeds in the soil sample. Then, after the weeding hook 407 rotates into the storage box 408, the storage box 408 blocks the grass and collects the grass.

[0043] Please refer specifically to Figure 7 The feeding mechanism 5 includes a driving component 501, a sliding frame 502, a second slider 503, a feeding plate 504, and a push rod 505. Two groups of sliding frames 502 are fixedly connected to the inner wall of the dust cover 401. A group of second sliders 503 are respectively slidably connected to the inner walls of the two groups of sliding frames 502. A group of feeding plates 504 are fixedly connected between the two groups of second sliders 503. One end of a push rod 505 is fixedly connected to the top end of the feeding plate 504. A driving component is fixedly connected to the top end of the dust cover 401. The other end of the push rod 505 is fixedly connected to the inside of the driving component. The driving component includes a housing 5010, a fourth gear 5011, a rack 5012, a fifth gear 5013, a sixth gear 5014, a second pulley set 5015, and a third pulley set 5016. The housing 5010 is fixedly connected to the top end of the dust cover 401. The fourth gear 5011 is rotatably connected to the inner wall of the housing 5010. The rack 5012 is fixedly connected to the side wall of the outer shell 303. The rack 5012 meshes with the fourth gear 5011. The fifth gear 5013 is rotatably connected to the inner wall of the housing 5010. The sixth gear 5014 is rotatably connected to the inner wall of the housing 5010. The fifth gear 5013 meshes with both the fourth gear 5011 and the sixth gear 5014. One end of the second pulley set 5015 is fixedly connected to the side wall of the sixth gear 5014. The other end of the second pulley set 5015 is fixedly connected to the third pulley set 5016. The outer wall of the third pulley set 5016 is fixedly connected to the other end of the push rod 505.

[0044] When the outer shell 303 moves downward, the fourth gear 5011 is driven to rotate through the rack 5012, so that the third pulley set 5016 rotates, and the feeding plate 504 slides into the dust cover 401, so that the feeding plate 504 does not block the downward movement of the drill bit 306. During the upward movement of the outer shell 303, the fourth gear 5011 is driven to rotate in the reverse direction through the rack 5012, so that the feeding groove is reset, thereby guiding the soil sample, so that the soil sample can slide onto the vibrating screen 403.

[0045] Working principle: The rotation of the first motor 304 drives the rotation of the transmission shaft 305 and the first gear 307. The transmission shaft 305 drives the rotation of the drill bit 306. The first gear 307 drives the rotation of the third gear 310 through the second gear 308. The third gear 310 drives the rotation of the threaded sleeve 309. Thus, the thread between the threaded sleeve 309 and the threaded rod 311 pushes the housing 303 to move downward. When the housing 303 moves downward, it drives the fourth gear 5011 to rotate through the rack 5012. The fourth gear 5011 drives the rotation of the fifth gear 5013. The fifth gear 5013 drives the rotation of the sixth gear 5014. The sixth gear 5014 drives the rotation of the third pulley set 5016 through the second pulley set 5015. The third pulley set 5016 drives the push rod 505 to translate, so that the push rod 505 pushes the second slider 503 to slide inside the sliding frame 502 through the material guide plate 504, so that the material guide plate 504 will not block the downward movement of the drill bit 306 when it moves away from below the drill bit 306. Thus, it realizes driving the drill bit 306 to rotate and move downward. The drill bit 306 passes through the sampling hole 2 and contacts the ground and continues to move downward and rotate. At this time, the helical teeth 3064 contact the soil, so that the drill bit 306 is more likely to break through the soil, and thus fill the soil sample into the drill bit 306. During this process, the sliding plate 3063 inside the drill bit 306 is pushed upward by the soil to move the ejector rod 3062 upward. Then the first motor 304 rotates in the reverse direction, so that the drill bit 306 rotates in the reverse direction and moves upward. Because the soil is filled tightly enough inside the casing 3061, it will not fall. During the upward movement of the housing 303, it drives the rack 5012 to move upward. When the rack 5012 contacts the fourth gear 5011, it drives the fourth gear 5011 to rotate in the reverse direction. Thus, the fourth gear 5011 drives the fifth gear 5013 to rotate in the reverse direction. The fifth gear 5013 drives the sixth gear 5014 to rotate in the reverse direction. The sixth gear 5014 drives the second pulley to rotate in the reverse direction. The second pulley drives the third pulley to rotate in the reverse direction. Thus, the third pulley drives the push rod 505 to move in the reverse direction. The push rod 505 drives the material guide plate 504 to move in the reverse direction and reset. When the drill bit 306 moves to a sufficient height, the first motor 304 is turned off. At this time, the material guide plate 504 just moves to below the drill bit 306. Then, push the two ejector rods 3062 to make the sliding plate 3063 slide downward, so that the soil sample is pushed out of the casing 3061 and falls into the pouring plate. Then the soil sample slides into the screening mechanism 4 through the material guide plate 504 and falls onto the vibrating screen 403. The rotation of the second motor 405 drives the rotation of the connecting shaft 4042. The connecting shaft 4042 drives the rotation of the first rotating shaft 4046 through the tension belt 4045. The first rotating shaft 4046 drives the rotation of the eccentric wheel 4043. Since the center of the eccentric wheel 4043 is not at the same point as the center of the circle of the first rotating shaft 4046, the rotation of the eccentric wheel 4043 will generate vibration, so that the casing 4041 drives the vibrating plate 402 and the vibrating screen 403 to vibrate, so as to screen the soil sample.Caked soil, stones and weeds are left on the vibrating screen 403, and the fine-grained soil falls onto the vibrating plate 402. During the rotation of the second motor 405, the second rotation is driven by the first pulley set 409. The second rotation drives the weed hook 407 to rotate, so that the weed hook 407 hooks the weeds. When the weed hook 407 passes through the slot on the storage frame 408, the weeds are blocked by the storage frame 408, and then the soil sample falls into the two sets of collection boxes 410 along with the vibration of the vibrating plate 402 and the vibrating screen.,

[0046] During use, the first motor 304 is the power source for the sampling mechanism 3 during the operation of the device, driving the drill bit 306 to rotate and move downward. The drill bit 306 passes through the sampling hole 2 and contacts the ground, continuously moving downward and rotating, so as to fill the soil sample into the drill bit 306. During this process, the sliding plate 3063 inside the drill bit 306 moves upward to push the ejector rod 3062 upward. Then the first motor 304 rotates in the reverse direction, causing the drill bit 306 to rotate in the reverse direction and move upward. When the drill bit 306 moves to a sufficient height, the first motor 304 is turned off, and then the two sets of ejector rods 3062 are pushed to make the sliding plate 3063 slide downward, so that the soil sample enters the screening mechanism 4 through the feeding mechanism 5. The second motor 405 drives the vibrating plate 402 and the vibrating screen 403 to vibrate through the vibrating component 404 to screen the soil sample. The soil samples on the vibrating plate 402 and the vibrating screen 403 enter the two sets of collection boxes 410 respectively along with the vibration of the vibrating plate 402 and the vibrating screen 403. During the process of driving the vibrating component 404 by the motor, the power of the second motor 405 is transmitted to the tension belt 4045 through the connecting shaft 4042 and then transmitted to the first rotating shaft 4046, so that a flexible connection is established between the motor and the first rotating shaft 4046, so that the vibrating component 404 is not easily driven to vibrate the motor during vibration, and the vibrating plate 402 is connected to the base 1 through a spring, so that the vibrating plate 402 is not easily driven to vibrate the base 1 together during vibration.
