Description

Technical Field

[0001] The present application relates to the technical field of data collection, and in particular to a device and method for collecting soil samples in urban green spaces. Background Art

[0002] From the perspective of urban ecological security and biodiversity protection, taking urban green space as the research object, by studying the impact of urban regional green space landscape pattern on urban biodiversity at the mesoscale, and studying the impact of landscape element structure, habitat characteristics and ecological processes of typical urban green space on urban biodiversity at the microscale, the key factors affecting urban biodiversity under different scale conditions are explored. By collecting urban green space soil and analyzing detailed data of soil in different regions, it is convenient to divide the main urban green space into park green space, protective green space, square land, ancillary green space and regional green space, so as to construct the urban green space landscape for biodiversity protection in a scientific way.

[0003] Soil refers to a loose layer of material on the surface of the earth, composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. The assessment of the microbial mass level and mineral mass level in the soil requires the use of professional data acquisition devices for the soil. Therefore, when studying urban green space data, the soil samples of the green space are collected for research and analysis, which can effectively derive the ecological environment of the green space, thereby facilitating the judgment of what type of green space is suitable, such as park green space, protective green space, etc.

[0004] The existing soil collection devices generally collect soil samples by drilling directly into the soil layer through a drill bit, but the drill bit drills directly from the soil surface downwards, that is, the soil sample collected by the drill bit is only the soil on the surface of the soil. When it is necessary to collect soil from deep inside, the soil on the surface of the soil will also be collected together, which will affect the collection of soil samples.

[0005] Secondly, most of the existing collection devices currently store the collected samples in the collection device after collecting soil once, which will delay the collection of other soil samples by the collection device again.

[0042] See also Figure 6 , Figure 7 , Fig. 9 and Fig.10 The collecting component 5 includes a collecting tube 51 which passes through from top to bottom. A mounting circular hole is provided on the flat plate 11, and a circular plate 52 is installed in the mounting circular hole. An adapting circular hole for the collecting tube 51 to slide through is provided at the center of the circular plate 52. A driving assembly 53 for driving the collecting tube 51 to move up and down is provided at the bottom of the circular plate 52. A center rod 54 is provided in the collecting tube 51, and a spiral blade 55 is provided on the center rod 54. A circular plate 56 is provided at the upper end of the collecting tube 51, and a plurality of connecting rods 57 connected to the upper end of the collecting tube 51 are provided on the side wall of the circular plate 56.

[0043] During specific work, the staff pushes the cart 1 to move to the green soil. When soil samples need to be collected, the push rod 1 33 first pushes the slider 31 to move to one side of the door-shaped bracket 2 and is located directly above the storage rack 43. At this time, the push rod 2 34 pushes the installation box 35 to move downward, and the installation box 35 drives the connecting box 38 to move downward synchronously through the connecting rack 36 until the connecting box 38 is connected to the storage rack 43 located between the baffles 42 on both sides, and then the push rod 2 34 moves up and resets, driving the storage rack 43 connected to the connecting box 38 to move upward synchronously, and then the push rod 1 33 drives the slider 31 to move and reset to directly above the collection tube 51, and again drives the storage rack 43 connected to the connecting box 38 to move downward through the push rod 2 34, and realizes that the storage rack 43 is set on the outer wall of the collection tube 51.

[0044] Next, the driving assembly 53 starts to drive the collecting tube 51 to move downward into the soil, and drives the central rod 54 to rotate through the motor 2 58, and then the spiral blade 55 starts to rotate in the collecting tube 51 to transport the soil in the collecting tube 51 upward, and then discharge it outward from between the several connecting rods 57 at the upper end of the collecting tube 51, so as to enter the storage rack 43 outside the collecting tube 51, and collect the collected soil. Finally, the storage rack 43 is placed on the annular plate 41, so as to realize the collection, collection and storage of the soil at one time.

[0045] See also Figure 6 , Figure 7 and Figure 8 The storage rack 43 is composed of a plurality of collecting tubes, and the collecting tube includes an annular bottom plate 431 at the bottom, an outer ring plate 432 is provided on the outer side of the annular bottom plate 431, and an inner ring plate 433 is provided on the inner side of the annular bottom plate 431, and the height of the inner ring plate 433 is lower than the height of the outer ring plate 432. The annular bottom plate 431, the inner ring plate 433 and the outer ring plate 432 together constitute a collection area for storing soil samples. The collecting tube 51 is penetrated on the inner ring plate 433, that is, the inner side surface of the inner ring plate 433 is in contact with the outer side surface of the collecting tube 51. When the soil sample in the collecting tube 51 moves up to the top of the collecting tube 51 through the spiral blade 55, the soil sample is discharged outward from between the plurality of connecting rods 57, and enters the collecting area through the top of the inner ring plate 433.

[0046] An internal thread ring 434 is provided on the outer side of the bottom of the outer ring plate 432, and an external thread 435 is provided on the top side wall of the outer ring plate 432, that is, the two collecting tubes in the upper and lower directions are connected by the threaded cooperation of the internal thread ring 434 and the external thread 435, that is, several collecting tubes are longitudinally connected in sequence to form a storage rack 43, thereby realizing the collection of soil samples at different depths of green space soil and separate collection and storage of different areas.

[0047] Since the collecting tube 51 gradually moves downward into the soil for collection, that is, it first collects from the upper layer of the soil downward, the collected upper layer of soil will be collected in the collecting tube on the upper side of the storage rack 43, that is, soil samples of different depths from top to bottom will be distributed in several collecting tubes along the storage rack 43 from top to bottom.

[0048] See also Figures 2 to 4 The annular plate 41 is provided with an annular guide rail 411, and the inner thread ring 434 of the collecting cylinder at the bottom of the storage rack 43 is provided with an adapting hole 436 that is slidably matched with the annular guide rail 411. The stability of the storage rack 43 is ensured by providing the annular guide rail 411.

[0049] A gear ring 21 is provided on the outer wall of the outer side baffle 42, and a rotating shaft 22 is rotatably provided on one side of the vertical section of the door-shaped bracket 2. A transposition gear 23 meshing with the gear ring 21 is provided at the bottom of the rotating shaft 22, and a transmission gear 24 is installed on the upper end of the rotating shaft 22 through a ratchet pawl. A rack 25 meshing with the transmission gear 24 is provided at the bottom of the slider 31.

[0050] During specific operation, after the slider 31 drives the connecting box 38 to move to the top of a storage rack 43 on the annular guide rail 411, the push rod 2 34 drives the connecting box 38 to connect with the storage rack 43, and then drives the storage rack 43 to move up, and with the assistance of the push rod 1 33, it is sleeved on the outer wall of the collection tube 51, and after taking out the soil sample collected in the collection tube 51, the push rod 2 34 drives the storage rack 43 to move up, and then the push rod 1 33 pushes the storage rack 43 to move to the top of the initial position, and then the storage rack 43 is moved down and reset to the initial position under the push of the push rod 2 34, and then the push rod 2 34 is moved up and reset.

[0051] If it is necessary to continue collecting soil samples and a new storage rack 43 is needed, the push rod 33 pushes the slider 31 to continue moving, so that the rack 25 engages with the transmission gear 24, driving the rotating shaft 22 to rotate, and then the transposition gear 23 rotates synchronously, and the transposition gear 23 engages with the ring gear 21, thereby realizing the rotation of the side baffle 42, that is, the annular plate 41, the annular guide rail 411 and the plurality of storage racks 43 thereon rotate synchronously, and all the storage racks 43 are transferred to one workstation.

[0052] Then, when the push rod 1 33 drives the slider 31 to move back to the top of the storage rack 43, the rack 25 will also move synchronously, but due to the cooperation of the ratchet pawl, the transmission gear 24 will not drive the rotating shaft 22 to rotate, that is, it is prevented that the storage racks 43 on the annular guide rail 411 move back to the initial position. At the same time, the push rod 2 34 drives the connection box 38 to reconnect with the new storage rack 43 below, so as to continue to move downward to collect, collect and store the soil samples.

[0053] See also Figure 7 The top outer wall of the connecting box 38 is set to a conical structure, and the bottom inner wall of the connecting box 38 is provided with an internal thread that meshes with the external thread 435 of the outer ring plate 432. When the motor 1 37 starts to drive the connecting frame 36 to rotate, it will drive the connecting box 38 to rotate synchronously, and with the cooperation of the push rod 2 34, the connecting box 38 can be spirally connected with the external thread 435 of the collecting tube at the top of the storage rack 43.

[0054] When the soil on the soil surface does not need to be collected, the upper soil first collected by the collecting tube 51 will be discharged outward from its top, and then will fall on the conical surface of the upper layer of the connecting box 38, and then fall downward to the circular plate 52, and finally be discharged from a number of discharge holes opened on the circular plate 52, and the required soil samples of different depths will be collected in turn into a number of collecting tubes distributed from top to bottom on the storage rack 43.

[0055] See also Fig. 9 and Fig.10The driving assembly 53 includes a mounting ring 531, which is mounted on the bottom of the circular plate 52 and is coaxially distributed with the collecting tube 51. A driving motor (not shown in the figure) is mounted on one side of the mounting ring 531 through a motor housing 532, and a driving gear 533 is mounted on the output end of the driving motor. A driven gear 534 is rotatably provided at the bottom of the circular plate 52 and is threadedly connected to the outer wall of the collecting tube 51.

[0056] Specifically, when the driving motor drives the driving gear 533 to rotate, the driving gear 533 realizes the rotation of the driven gear 534 by meshing with the driven gear 534, and the driven gear 534 is threadedly connected to the collecting tube 51. Therefore, when the driven gear 534 rotates, the collecting tube 51 will move along its axial direction, that is, the collecting tube 51 is controlled to go deep into the soil to collect samples and move up and reset after the collection is completed.

[0057] See also Fig.11 A plurality of mounting brackets 5311 are provided on the inner side of the mounting ring 531 , a sponge 5312 is detachably mounted on one of the mounting brackets 5311 , and brushes 5313 are detachably mounted on the other mounting brackets 5311 .

[0058] When the collecting tube 51 completes collection and moves upward from the soil, a lot of dirt will adhere to the outer wall of the collecting tube 51. In order to ensure smooth threaded movement of the driven gear 534 and the collecting tube 51, the brush 5313 scrapes the dirt from the outer wall of the collecting tube 51, and the sponge 5312 wipes the dirt adhered to the outer wall of the collecting tube 51 to ensure the cleanliness of the outer wall of the collecting tube 51.

[0059] In addition, the present invention also provides a method for collecting urban green space soil samples, and the collection method is as follows:

[0060] Step 1: The staff pushes the cart 1 to move to the green soil. When soil samples need to be collected, the push rod 1 33 first pushes the slider 31 to one side of the door-shaped bracket 2 and is located directly above the storage rack 43. At this time, the push rod 2 34 pushes the installation box 35 to move downward, and the installation box 35 drives the connecting box 38 to move downward synchronously through the connecting rack 36 until the connecting box 38 is connected to the storage rack 43 located between the baffles 42 on both sides, and then the push rod 2 34 moves up and resets, driving the storage rack 43 connected to the connecting box 38 to move upward synchronously, and then the push rod 1 33 drives the slider 31 to move and reset to directly above the collection tube 51, and again drives the storage rack 43 connected to the connecting box 38 to move downward through the push rod 2 34, and realizes that the storage rack 43 is set on the outer wall of the collection tube 51.

[0061] Step 2: The driving assembly 53 starts to drive the collecting tube 51 to move downward into the soil, and drives the central rod 54 to rotate through the motor 2 58, and then the spiral blade 55 starts to rotate in the collecting tube 51 to transport the soil in the collecting tube 51 upward, and then discharge it outward from between the several connecting rods 57 at the upper end of the collecting tube 51, so as to enter the collecting tube outside the collecting tube 51 to realize the collection of the collected soil, and finally the storage rack 43 is placed on the annular plate 41 through the push rod 1 33 and the push rod 2 34, so as to realize the collection, collection and storage of the soil once.

[0062] Step 3: If it is necessary to continue collecting soil samples and a new storage rack 43 is needed, the push rod 33 pushes the slider 31 to continue moving, so that the rack 25 engages with the transmission gear 24, driving the rotating shaft 22 to rotate, and then the transposition gear 23 rotates synchronously, and the transposition gear 23 engages with the ring gear 21, thereby realizing the rotation of the side baffle 42, that is, realizing the synchronous rotation of the annular plate 41, the annular guide rail 411 and the plurality of storage racks 43 thereon, realizing the transfer of all the storage racks 43 to one station, and then continuing to repeat steps 1 and 2 to realize the collection, collection and storage of soil in another area.

[0063] Step 4: When the soil on the soil surface does not need to be collected, the upper soil first collected by the collecting tube 51 will be discharged outward from its top, and then will fall on the conical surface of the upper layer of the connecting box 38, and then fall downward to the circular plate 52, and finally be discharged from several discharge holes opened on the circular plate 52, and the required soil samples of different depths will be collected in turn into several collecting tubes distributed from top to bottom on the storage rack 43.

[0064] Step 5: After the driving assembly 53 drives the collecting tube 51 downward to collect the soil sample, the collecting tube 51 is driven upward to reset. At this time, the brush 5313 and sponge 5312 on the inner side of the mounting ring 531 clean the soil adhered to the outer wall of the collecting tube 51.

[0065] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
