Description

Technical Field

[0001] The invention relates to the technical field of soil collection, and in particular to a soil drilling device for layered soil collection and removal and a use method thereof. Background Art

[0002] In the research fields of environment, ecology, agriculture, forestry, geology, etc., collecting soil samples from different depths to determine the soil property parameters of the target soil layer is often an important research content. At present, the commonly used soil collection tools are mainly shovels and soil drills. Shovel soil collection is the most traditional and backward method. It has low soil collection efficiency and consumes manpower. When used for layered soil collection, its collection depth is not accurate enough, and the degree of damage to farmland during sampling is large; soil drill soil collection technology is widely used today, and when using ordinary soil drills, a plane for users to step on and apply force must be dug around the sampling point to collect soil. Moreover, whether it is for collecting surface soil or continuing to collect soil from below after the surface soil is taken out, it can only rely on both hands to apply force to the handle. After the surface soil is taken out, the soil debris and impurities around the sampling point are easy to slide down, which increases the resistance and interference of the lower soil collection. It can be seen that the ordinary soil drill soil collection technology is time-consuming and labor-intensive, and it cannot guarantee the accuracy of the soil collection depth, which affects the research results. It is not suitable for the soil collection scene of flooded soil, and it cannot achieve accurate soil removal and collection of specific soil layer samples after soil collection. Therefore, there is an urgent need to develop a new type of soil drilling device that can accurately extract and collect soil from soil layers at a specific depth and is suitable for different soil extraction scenarios.

[0003] The prior art discloses a technical solution for achieving layered soil extraction by providing a force handle and a push handle connected to each other, and then using scales and grooves (publication number: CN210533759U). However, this technical solution can only extract soil by applying hand force to the force handle to drive the soil drill downward to extract soil. When exerting force, the operator needs to maintain a half-squatting state for a long time, which is not conducive to exerting force and is difficult to persist for a long time, affecting the accuracy of controlling the soil extraction depth. At the same time, it is difficult for users with less hand strength to complete soil extraction independently.

[0004] The prior art also discloses a technical solution for obtaining soil samples at a specific depth by observing the depth of the auger tube below the ground through a scale and pressing the auger downward by hammering (publication number: CN206440485U). However, this technical solution requires the user to frequently swing the hammer during the sampling process, which is time-consuming, labor-intensive and very dangerous. At the same time, the force and striking point when using the hammer are difficult to be accurately controlled manually, and the depth below the ground cannot be accurately controlled to be exactly the target soil sampling depth.

[0005] The prior art also discloses a technical solution for locking the target depth by inserting a card into a card slot (publication number: CN207516066U), but the operation of this technical solution is cumbersome and only applicable to sampling of loose soil. Moreover, the setting of the target soil sampling depth is discontinuous and limited, and cannot meet the demand for sampling at any depth.

[0006] In addition, collecting the soil at a specific depth after taking the soil is also a key step. The prior art discloses a technical solution in which a horizontal plate of a detachable pedal is inserted into the top of a drill bit that accommodates the soil sample, so that the horizontal plate supports the soil sample and force is applied to the horizontal plate to push the soil block out of the drill bit (publication number: CN108593333A). However, the operation of removing and reinserting the horizontal plate in this technical solution is cumbersome, and it is time-consuming and laborious to push the soil out by applying force to the horizontal plate alone. Moreover, it is impossible to collect the soil from the soil drill at a specific depth after taking the soil.

[0007] In short, the above technical solutions cannot achieve accurate stratified soil collection and soil removal according to the target depth, and there are also problems such as cumbersome operation, time-consuming and labor-intensive, poor safety, and low efficiency. At the same time, they are not suitable for soil collection scenarios in flooded soil. Therefore, there is an urgent need for a new soil drilling device that can not only achieve accurate stratified soil collection and soil removal, but also be simple to operate, save time and effort, and be safe and efficient when used, and can also be applied to different soil types and soil collection scenarios.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0045] Combine the following Figures 1 to 9 The present invention is a soil drill device for layered soil extraction and soil removal (hereinafter referred to as the soil drill device), comprising a soil drill body 1, the soil drill body 1, which is composed of a main body 11, a main handle 12 and a soil extraction tube 13, wherein the main body 11 is provided with a soil extraction scale 14, the main handle 12 is connected to the upper end of the main body 11, and the soil extraction tube 13 is connected to the lower end of the main body 11. It should be noted that the main handle 12 and the main body 11 can be connected in an integral manner, or can be connected by a slot, a threaded interface, a lock, a hinge and other structures. The present invention is not particularly limited here, as long as the connection structure or method can achieve the connection and fixation of the main handle 12 and the main body 11.

[0046] like Figure 1 As shown, according to an embodiment of the present invention, the main body 11 serves as the main supporting structure of the earth drilling device, the main handle 12 serves as the direct acting structure that the user holds and presses downward during the soil extraction operation, and the soil extraction tube 13 serves as the soil entry and soil sample accommodating structure of the earth drilling device.

[0047] Preferably, the soil auger body 1 is made of stainless steel, the cross-sectional shape of the main body 11 is circular, with an outer diameter of 5-7 cm and a length of 100-120 cm, and the main handle 12 is in a straight line shape, with a length of 30-50 cm, and is perpendicular to the main body 11, that is, the main handle 12 forms a "T" shape with the main body 11. Of course, the main handle 12 can also be in other centrally symmetrical shapes, such as a right cross shape, a cross shape, etc., with the shape plane perpendicular to the main body 11 and a diameter greater than the cross-sectional diameter of the main body 11.

[0048] Preferably, a circular hole is provided at the center of the plane of the main handle 12, and the diameter of the circular hole is 3-5 cm.

[0049] like Figure 2As shown, according to an embodiment of the present invention, the soil collecting barrel 13 can be detached from the main body 11. It should be noted that the connection structure between the soil collecting barrel 13 and the main body 11 can be a slot, a threaded interface, a lock, a hinge, etc., and the present invention does not make any special restrictions here, as long as the connection structure can realize the separation of the soil collecting barrel 13 and the main body 11 by unlocking through the above structure.

[0050] like Figure 3 As shown, according to an embodiment of the present invention, the soil extraction tube 13 is a hollow tube with a diameter larger than the main tube 11. The soil extraction tube 13 can be set to different lengths according to the interval of each target soil extraction depth.

[0051] Preferably, the soil sampling tube 13 is made of stainless steel, has a circular cross-section, an outer diameter of 10-15 cm, and an inner diameter of 8-12 cm. Since the interval of each target soil sampling depth is usually set to 20 cm, the length of the soil sampling tube 13 is 20 cm, and the soil inlet port of the soil sampling tube 13 is a beveled elliptical cross-section blade. Of course, according to the different intervals of each target soil sampling depth, the soil sampling tube 13 can also be other lengths, such as 10 cm, 15 cm, 30 cm, etc.

[0052] like Figure 4 As shown, according to an embodiment of the present invention, the main body 11 is provided with a soil sampling scale 14 for determining the depth reached by the soil entry port of the soil sampling tube 13 when sampling soil.

[0053] Preferably, the soil sampling scale 14 is arranged on the outer wall of the main body 11, and the scale value increases from bottom to top, and the scale starting value is 20cm, which is equal to the length of the soil sampling tube 13. Of course, according to the different lengths of the soil sampling tube 13, the scale starting value can also be other values.

[0054] According to an embodiment of the present invention, the main body 11 is a hollow tube body with a bulldozer structure 2 inside. The bulldozer structure 2 can slide in the main body 11 and the soil-taking barrel 13, and is composed of a bulldozer handle 21, a bulldozer rod 22 and a bulldozer head 23. The bulldozer handle 21 and the bulldozer head 23 are respectively connected to the two ends of the bulldozer rod 22.

[0055] like Figure 5 As shown, the bulldozer structure 2 is arranged inside the main body 11, and is used to remove soil from the soil collecting tube 13 after soil is collected. The bulldozer structure 2 can slide in the main body 11 and the soil collecting tube 13 in the up-down direction, wherein the downward sliding occupies the internal space of the soil collecting tube 13, thereby pushing out the soil sample in the soil collecting tube 13, and the bulldozer head 23 can reach the soil inlet port of the soil collecting tube 13, and when collecting soil, the bulldozer structure 2 slides upward, thereby restoring the internal space of the soil collecting tube 13, so that the soil sample enters the soil collecting tube 13.

[0056] like Figure 5As shown, the bulldozer structure 2 is composed of a bulldozer handle 21, a bulldozer rod 22 and a bulldozer head 23, wherein the bulldozer handle 21 is connected to the upper end of the bulldozer rod 22, and the bulldozer head 13 is connected to the lower end of the bulldozer rod 22. The bulldozer handle 21 is used as a direct action structure pressed downward when removing soil and collecting, and the bulldozer rod 22 is used as the main supporting structure of the bulldozer structure 2. When removing soil, the user presses the bulldozer handle 21, so that the bulldozer rod 22 drives the bulldozer head 23 to slide downward in the main body 11 and the soil sampling tube 13, pushes out the soil sample in the soil sampling tube 13, and realizes soil removal and collection. Compared with the prior art, it is more labor-saving and efficient to remove soil and collect soil by applying force to the bulldozer handle 21 so that the bulldozer rod 22 drives the bulldozer head 23 to slide downward.

[0057] It should be noted that the connection method between the bulldozer handle 21 and the bulldozer rod 22 can be an integral connection, or it can be connected through a slot, a threaded interface, a lock, a hinge or other structures. The present invention does not make any special limitations here, as long as the connection method or structure can achieve the connection and fixation of the bulldozer handle 21 and the bulldozer rod 22.

[0058] Preferably, the bulldozer structure 2 is made of stainless steel and is in the shape of a straight rod. The cross-section of the bulldozer rod 22 is circular with a diameter of 1-3 cm. The length of the bulldozer rod 22 is 120-140 cm, which is equal to the sum of the lengths of the main body 11 and the soil extraction tube 13. Of course, the length of the bulldozer rod 22 can also be set to other lengths according to the length of the soil extraction tube 13.

[0059] Preferably, the bulldozer handle 21 is circular, and its diameter is larger than the circular hole in the center of the plane of the main handle 12, so that the bulldozer handle 21 is kept above the main handle 12. Of course, the bulldozer handle 21 can also be in other shapes, such as a straight line, square, spherical, ellipsoidal, etc., with a maximum diameter larger than the circular hole in the center of the plane of the main handle 12.

[0060] like Figure 6 As shown, according to an embodiment of the present invention, the bulldozer head 23 can be detached from the bulldozer rod 22. It should be noted that the detachable connection structure between the bulldozer head 23 and the bulldozer rod 22 can be a slot, a threaded interface, a lock, a hinge, etc., and the present invention does not make any special restrictions here, as long as the connection structure can achieve the bulldozer head 23 and the bulldozer rod 22 to be unlocked and separated through the above structure.

[0061] Preferably, the bulldozer head 23 is in the shape of a circular sheet with a thickness of 0.5-1 cm and a diameter of 7-11 cm, which is larger than the inner diameter of the main body 11 and smaller than the inner diameter of the soil-collecting barrel 13, so that the bulldozer head 23 can be kept below the main body 11 and can slide along the inner wall of the soil-collecting barrel 13, and can also avoid damage, disturbance and time-consuming and labor-intensive situations in the soil sample in the soil-collecting barrel 13 caused by the inappropriate shape and size of the bulldozer head 23 during bulldozing.

[0062] like Figure 7As shown, according to an embodiment of the present invention, the bulldozer rod 22 is provided with a soil removal scale 24. When removing soil, the depth of the soil sample pushed out of the soil collecting tube 13 by the bulldozer head 23 can be determined according to the soil removal scale 24 entering the main body 11 from the circular hole in the center of the main handle 12, thereby realizing soil removal and collection of soil at a specific depth.

[0063] Preferably, the soil removal scale 24 is provided on the outer wall of the bulldozer rod 22, and the scale value increases from top to bottom, the scale starting value is 0cm, and the scale end value is 20cm, which is equal to the length of the soil extraction tube 13. Of course, the scale end value can also be set to other values ​​according to the length of the soil extraction tube 13.

[0064] According to an embodiment of the present invention, the soil drilling device further comprises a foot pedal 3 , which is disposed on the main pipe body 11 via a connector and can slide along the main pipe body 11 .

[0065] like Figure 8 As shown, the foot pedal 3 is a direct action structure for stepping on and pressing downward when taking soil. The user applies force to the foot pedal 3 by stepping on it, so that the soil drill device moves downward and drives the soil taking tube 13 into the soil to complete soil taking. It should be noted that the foot pedal 3 is arranged on the main body through a connector, and the connector can be a ring, a ferrule, a sliding chain, etc. The present invention does not make any special restrictions here, as long as the connection structure can realize that the foot pedal 3 is arranged on the main body 11 and can slide along the main body 11.

[0066] Preferably, the foot pedal 3 is made of stainless steel and is in the shape of a rectangular sheet with a length of 15-22 cm, a width of 6-10 cm, and a thickness of 1-2 cm.

[0067] like Fig. 9 As shown, according to an embodiment of the present invention, the soil drilling device further includes a casing group 4 , which is composed of a plurality of casings 41 of different lengths. The casing 41 of each length can be sleeved and installed on the main pipe body 11 .

[0068] According to the embodiment of the present invention, after the main body 11 is separated from the soil collecting tube 13 and the bulldozer rod 22 is separated from the bulldozer head 23, the sleeve 41 of each length can be sleeved on the main body 11 from the lower end of the main body 11, and after the soil collecting tube 13 is connected to the main body 11, the sleeve 41 can be abutted against the upper end of the soil collecting tube 13 to complete the sleeve installation of the sleeve 41. The installed sleeve 41 can push the foot pedal 3 provided on the main body 11 to the upper end of the sleeve 41 to fix the foot pedal 3.

[0069] Preferably, each length of the sleeve 41 is made of stainless steel, has a circular cross-sectional shape, and a diameter greater than the outer diameter of the main body 11 and smaller than the outer diameter of the soil-extracting barrel 13, which is 9-12 cm. Therefore, after each length of the sleeve 41 is sleeved and installed on the main body 11, it can be ensured that the lower end of the sleeve 41 can be against the upper end of the soil-extracting barrel 13.

[0070] The prior art discloses a technical solution for achieving layered soil extraction by providing a force handle and a push handle connected to each other, and then using scales and grooves (publication number: CN210533759U). However, this technical solution can only extract soil by applying hand force to the force handle to drive the soil drill downward to extract soil. When exerting force, the operator needs to maintain a half-squatting state for a long time, which is not conducive to exerting force and is difficult to persist for a long time, affecting the accuracy of controlling the soil extraction depth. At the same time, it is difficult for users with less hand strength to complete soil extraction independently.

[0071] The prior art also discloses a technical solution for obtaining soil samples at a specific depth by observing the depth of the auger tube below the ground through a scale and pressing the auger downward by hammering (publication number: CN206440485U). However, this technical solution requires the user to frequently swing the hammer during the sampling process, which is time-consuming, labor-intensive and very dangerous. At the same time, the force and striking point when using the hammer are difficult to be accurately controlled manually, and the depth below the ground cannot be accurately controlled to be exactly the target soil sampling depth.

[0072] The prior art also discloses a technical solution for locking the target depth by inserting a card into a card slot (publication number: CN207516066U), but the operation of this technical solution is cumbersome and only applicable to sampling of loose soil. Moreover, the setting of the target soil sampling depth is discontinuous and limited, and cannot meet the demand for sampling at any depth.

[0073] The above technical solution cannot achieve accurate soil extraction according to the target depth, and has the problems of cumbersome operation, time-consuming and labor-intensive, poor safety, low efficiency, etc. In order to solve the above technical problems, according to an embodiment of the present invention, the soil drilling device also includes a foot pedal 3 and a casing group 4.

[0074] The foot pedal 3 is a direct action structure for stepping on and pressing down when taking soil. The user applies force to the foot pedal 3 by stepping on it, so that the soil drill device moves downward and drives the soil extraction tube 13 into the soil to complete soil taking. That is to say, when taking soil, the user holds and presses the main handle 12 downward, and can also use the power of the foot to press the soil extraction tube 13 downward. The soil drill device moves downward and drives the soil extraction tube 13 into the soil through the combination of hands and feet. For soils with hard and loose texture, it can achieve time-saving, labor-saving, simple, convenient, safe and efficient soil taking operations, effectively solve the problems of insufficient hand strength of the user, difficulty in maintaining the half-squatting state and inconvenience in exerting force, and avoid the cumbersome and dangerous operation of swinging a hammer to press down the soil drill device.

[0075] The sleeve assembly 4 is composed of a plurality of sleeves 41 of different lengths. Each sleeve 41 of different lengths can be sleeved and installed on the main pipe 11 .

[0076] like Figure 2As shown, after the main body 11 is separated from the soil taking tube 13 and the bulldozer rod 22 is separated from the bulldozer head 23 , the user can install a sleeve 41 of a length selected according to the target soil taking depth from the lower end of the main body 11 onto the main body 11 .

[0077] like Figure 1 As shown, after the selected sleeve 41 is sleeved and installed on the main body 11, the main body 11 is connected to the soil extraction tube 13, and the lower end of the selected sleeve 41 can be against the upper end of the soil extraction tube 13. At this time, the foot pedal 3 is fixed to the upper end of the selected sleeve 41, and the fixed position corresponds to the soil extraction scale 14 related to the target soil extraction depth. When extracting soil, the user can apply force to the foot pedal 13 to drive the soil extraction tube 13 to move downward. During the movement, the soil extraction scale 14 corresponding to the foot pedal 3 is used to determine whether the soil inlet port of the soil extraction tube 13 has reached the target soil extraction depth, thereby achieving accurate positioning of the target soil extraction depth. The superimposed installation or replacement installation of other sleeves 41 can also be used to complete soil collection at different depths at the same sampling point, effectively solving the problem that the prior art cannot accurately control and ensure that the soil drilling device extracts soil at the target depth.

[0078] It should be noted that the foot pedal 3 is arranged on the main body 11 and can slide along the main body 11, ensuring that the foot pedal 3 can be fixed to the upper end of the sleeve 41 of any length, that is, corresponding to any scale of the soil sampling scale 14, thereby ensuring that soil can be sampled at any depth, solving the problem that the prior art cannot sample soil at any depth.

[0079] In addition, collecting the soil at a specific depth after taking the soil is also a key step. The prior art discloses a technical solution in which a horizontal plate of a detachable pedal is inserted into the top of a drill bit that accommodates the soil sample, so that the horizontal plate supports the soil sample and force is applied to the horizontal plate to push the soil block out of the drill bit (publication number: CN108593333A). However, the operation of removing and reinserting the horizontal plate in this technical solution is cumbersome, and it is time-consuming and laborious to push the soil out by applying force to the horizontal plate alone. Moreover, it is impossible to collect the soil from the soil drill at a specific depth after taking the soil.

[0080] In order to solve the above technical problems, according to an embodiment of the present invention, a bulldozer structure 2 is provided inside the main body 11, which is used to remove soil from the soil sampling tube 13 after soil is taken. The bulldozer structure 2 is composed of a bulldozer handle 21, a bulldozer rod 22 and a bulldozer head 23, wherein the bulldozer rod 22 is provided with a soil removal scale 24, which is used to determine the depth of the soil sample pushed out of the soil sampling tube 13 by the bulldozer head 23.

[0081] like Figure 5As shown, the bulldozer structure 2 can slide in the main body 11 and the soil collecting tube 13 in the up-down direction, wherein the downward sliding occupies the internal space of the soil collecting tube 13, thereby pushing out the soil sample in the soil collecting tube 13, and the bulldozer head 23 can reach the soil inlet port of the soil collecting tube 13 and push out all the soil samples in the soil collecting tube 13. The bulldozer handle 21 is a direct action structure for pressing downward when removing soil. Compared with the prior art, by applying force to the bulldozer handle 21, the bulldozer rod 22 drives the bulldozer head 23 to slide downward along the inner wall of the soil collecting tube 13, so that the soil samples in the soil collecting tube 13 can be pushed out for soil removal and collection in a more labor-saving and efficient manner.

[0082] like Figure 5 As shown, when removing soil, the user can push out the soil of a specific depth according to the soil removal scale 24 provided on the push rod 22, thereby realizing the soil removal and collection of soil at a specific depth, so that the collected soil sample accurately corresponds to the soil layer and is more representative.

[0083] Furthermore, the existing technical solutions are not applicable to the soil extraction scenario of flooded soil. In order to solve the above technical problems, a method for using a soil drilling device for layered soil extraction and soil removal in an embodiment of the present invention includes the following steps:

[0084] 1. For the soil sampling scenario of terrestrial (non-flooded) soil, when the target soil sampling depth is greater than the length of the soil sampling tube 13, a sleeve 41 with a suitable length is selected according to the target soil sampling depth. The sum of the length of the selected sleeve 41 plus the length of the soil sampling tube 13 is the target soil sampling depth.

[0085] 1) Installation steps: After the main body 11 is separated from the soil-taking barrel 13 and the bulldozer rod 22 is separated from the bulldozer head 23, the selected sleeve 41 is installed on the main body 11 so that the foot pedal 3 provided on the main body 11 is located at the upper end of the selected sleeve 41, and then the main body 11 is connected to the soil-taking barrel 13, and the bulldozer head 23 is connected to the bulldozer rod 22, so that the lower end of the selected sleeve 41 is against the upper end of the soil-taking barrel 13, and the foot pedal 3 is fixed to the soil-taking scale 14 corresponding to the target soil-taking depth.

[0086] 2) Soil sampling step: Place the soil drill device with the foot pedal 3 fixed on it at the sampling point, hold and press the main handle 12 downward, and at the same time press the foot pedal 3 by foot to move the soil drill device downward, driving the soil sampling tube 13 into the soil. When the soil sampling scale 14 corresponding to the foot pedal 3 reaches the soil surface, the soil inlet port of the soil sampling tube 13 reaches the target soil sampling depth, realizing accurate sampling of the target soil sampling depth.

[0087] 3) Soil removal step: Press the bulldozer handle 21, drive the bulldozer head 23 to slide downward through the bulldozer rod 22, push out the soil sample in the soil sampling tube 13, and realize soil removal and collection from the soil drill device. At the same time, the depth of the soil sample pushed out by the bulldozer head 23 can be determined according to the soil removal scale 24 entering the main body 11 from the circular hole in the center of the main handle 12, so as to realize soil removal and collection from the soil drill at a specific depth.

[0088] When sampling continues downward at the same sampling point, other sleeves 41 of suitable length are superimposed or replaced on the main pipe body 11 according to the depth of the lower soil sampling. The installation, soil sampling and soil removal steps are the same as 1) to 3) above.

[0089] When the target soil extraction depth is not greater than the length of the soil extraction tube 13, there is no need to install the sleeve 41. The foot pedal 13 can be fixed against the upper end of the soil extraction tube 13. When soil is extracted, the soil is extracted when the foot pedal 13 reaches the soil surface, and then the soil is pushed out to a specific depth according to the soil removal scale 24 to complete the soil removal and collection.

[0090] 2. For soil sampling scenarios in flooded soil, the water depth needs to be measured. When the sum of the target soil sampling depth plus the water depth is greater than the length of the soil sampling tube 13, a casing 41 with an appropriate length is selected according to the target soil sampling depth. The sum of the selected casing 41 and the length of the soil sampling tube 13 minus the water depth is the target soil sampling depth.

[0091] The installation steps are the same as those in 1) above. When taking soil, force is applied to the foot pedal 3 to drive the soil taking barrel 13 into the soil. When the soil taking scale 14 corresponding to the foot pedal 3 reaches the water surface, the soil inlet port of the soil taking barrel 13 reaches the target soil taking depth, thereby achieving accurate soil taking to the target depth without being affected by flooding. The soil removal steps are the same as those in 3) above.

[0092] When sampling continues downward at the same sampling point, other sleeves 41 of suitable length are superimposed or replaced on the main pipe body 11 according to the soil sampling depth of the lower layer. When the soil sampling scale 14 corresponding to the pedal 3 reaches the water surface, the soil inlet port of the soil sampling tube 13 reaches the target soil sampling depth.

[0093] When the sum of the target soil extraction depth and the water depth is not greater than the length of the soil extraction barrel 13, there is no need to install the sleeve 41. The foot pedal 13 can be fixed against the upper end of the soil extraction barrel 13. When soil is extracted, the soil extraction is completed when the soil extraction scale 14 corresponding to the foot pedal 3 reaches the water surface, and then the soil at a specific depth is pushed out according to the soil removal scale 24 to complete the soil removal and collection.

[0094] In summary, the present invention provides a soil drilling device and a method of use for layered soil extraction and removal, which solve the problems that existing soil drilling devices are unable to accurately extract and remove soil in layers, as well as the limitations of soil types and applicable scenarios. It can not only achieve accurate layered soil extraction and soil removal and collection, but also is simple and convenient to operate, saves time and effort, is safe and efficient, effectively improves the efficiency and accuracy of soil collection for different types and scenarios, and has a wide range of applications.
