Description

Technical Field

[0001] The invention belongs to the technical field of sampling devices, and in particular relates to a soil sampling device for land reclamation. Background Art

[0002] Land reclamation refers to the reclamation of inefficiently used, irrationally used, and unused land. In the process of land reclamation, soil sampling and testing is an extremely important link. The soil in different regions differs in composition, structure, fertility, pH, etc. These characteristics directly affect the selection and implementation of land reclamation measures.

[0003] At present, a simple sampling tube is usually used for sampling. Generally, after the sampling tube is inserted into the soil, the staff lifts the handle on the top of the sampling tube, and the sampling tube brings up the soil sample. Then a sharp object is used to dig the soil sample out of the sampling tube. Then the staff crushes the lumps in the soil sample and puts the soil sample into a bag.

[0004] In order to solve the inconvenience caused by the need to manually dig out soil samples from the sampling tube in the prior art, the utility model patent with the authorization announcement number CN218916864U discloses a device that can be used for sampling in frozen soil areas, which includes a sampling tube, a push rod, and a push head. The interior of the sampling tube is provided with an internal thread ring, the push rod is threadedly assembled on the internal thread ring, and the push head is installed on the push rod. When in use, the sampling tube is inserted into the soil and the soil sample is taken out. The push rod is rotated, and the push rod drives the push head to move toward the sampling port at the bottom of the sampling tube. The push head pushes the soil sample out of the sampling tube, and there is no need to manually dig out the soil sample from the sampling tube.

[0005] Although the existing technology can solve the problem of soil samples falling out of the sampling tube, after the soil samples fall out, workers still need to manually crush the lumps in the soil samples to ensure sample uniformity and facilitate bagging. Manually crushing soil samples is inefficient and easily causes hand fatigue, which brings inconvenience to the sampling work. Summary of the invention

[0006] The invention provides a soil sampling device for land reclamation, so as to solve the technical problem in the prior art that lumps in soil samples need to be manually crushed, which brings inconvenience to the sampling work.

[0007] In order to solve the above problems, the soil sampling and testing device for land reclamation provided by the present invention adopts the following technical solutions: a soil sampling and testing device for land reclamation, comprising a sampling tube structure, a handle arranged on the top of the sampling tube structure, a crushing structure, and a force applying structure; The sampling barrel structure comprises a square sampling barrel and a barrel cover. The bottom of the square sampling barrel is lower in front and higher in the back and is arranged obliquely. The square sampling barrel comprises a barrel body and a sealing plate. The barrel body is provided with a rear opening and a bottom opening. The sealing plate is slidably assembled in the rear opening along the up and down direction to close the rear opening. The upper end of the sealing plate extends to the top of the barrel body. The top of the sealing plate is provided with a horizontal plate that is slidably sleeved on the handle up and down; barrel cover sliding grooves are provided on the left and right sides of the inner part of the barrel body at the bottom opening, and the barrel cover sliding grooves are arranged parallel to the bottom surface of the square sampling barrel; the left and right sides of the bottom of the barrel cover are slidably assembled in the barrel cover sliding grooves through a pin shaft, and the top of the barrel cover is connected to the bottom of the sealing plate so that the sealing plate drives the barrel cover to slide reciprocally, and the sliding stroke of the barrel cover has a closing position for closing the bottom opening, and also has a letting position for opening the bottom opening and closing the rear opening together with the sealing plate; The crushing structure includes a crushing rod mounted on the handle and rotating around an axis extending up and down, and a crushing blade arranged on the crushing rod and located in a square sampling tube; the force-applying structure includes a force-applying seat slidably sleeved on the outside of the handle along the up and down directions, and the force-applying seat is used to apply downward force to the horizontal plate.

[0008] When in use, the cylinder cover is first in the open position, the cylinder cover and the sealing plate jointly close the rear opening of the cylinder, the square sampling cylinder is inserted into the soil, and the soil sample enters the space surrounded by the cylinder, the cylinder cover and the sealing plate. The operator then applies force downward to the force-applying seat, and the force-applying seat pushes the horizontal plate and the sealing plate downward, and the sealing plate pushes the cylinder cover downward. The cylinder cover slides obliquely downward to gradually close the bottom opening of the cylinder, and at the same time cuts off the connection between the soil sample and the external soil. The sealing plate alone closes the rear opening of the cylinder. At this time, the bottom of the cylinder is closed, the crushing rod in the crushing structure rotates, and the crushing blades crush the lumps in the soil sample. In the soil sampling and testing device for land reclamation of the present invention, the bottom surface of the square sampling cylinder is an inclined surface, which is convenient for inserting into the soil. By setting a slidable cylinder cover, on the one hand, it can cut off the connection between the soil sample and the external soil; on the other hand, it can form a closed space together with the square sampling cylinder when the crushing structure rotates and crushes, so that the crushing structure can fully crush the soil sample in the space, improve the crushing effect, and avoid the problems of low efficiency and hand fatigue caused by manual hand-kneading. Since the cylinder cover closes the bottom opening of the square sampling cylinder, when the crushing is completed and the soil sample is pulled out of the soil, the crushed soil sample will not fall out of the square sampling cylinder, and the sampling can be carried out smoothly.

[0009] As a further improvement, the bottom of the handle is provided with a breaker rod through hole, and the side is provided with an avoidance groove connected to the breaker rod through hole and extending up and down; The breaker rod is inserted into the breaker rod through hole, and one of the outer portion of the breaker rod and the hole wall of the breaker rod through hole is provided with a spiral groove, and the other is provided with a sliding protrusion that slides with the spiral groove; The force applying seat is provided with a pressing protrusion which passes through the avoidance groove and presses the crushing rod downward; The crushing structure also includes a crushing rod reset spring for applying an upward pushing force to the crushing rod. Through the cooperation of the spiral groove and the sliding protrusion, the crushing rod can rotate during the up and down movement; the force seat can not only press down the cross plate, but also press down the crushing rod, with more centralized functions and convenient operation for the staff.

[0010] As a further improvement, the breaker rod comprises a breaker rod large diameter section located at the top and a breaker rod small diameter section located at the bottom to form a second step facing downwards, and the breaker rod small diameter section penetrates downwards into the square sampling tube; The breaker rod reset spring is sleeved on the outside of the breaker rod small diameter section and is elastically pressed between the second step and the top of the sampling tube structure. The breaker rod reset spring can exert an upward force on the breaker rod, so as to facilitate the upward reset of the breaker rod.

[0011] As a further improvement, the sampling tube structure also includes a sealing plate reset spring sleeved on the outside of the handle, which is used to apply an upward elastic force to the transverse plate so that the sealing plate pulls the tube cover upward and drives the tube cover from the closed position to the open position.

[0012] As a further improvement, an elastic locking member is provided on the inner side of the transverse plate, the elastic locking member includes a locking block and a locking block spring connecting the locking block and the transverse plate, and a locking groove is provided on the handle for the locking block to extend into so as to keep the cylinder cover in a closed position; The soil sampling and testing device for land reclamation also includes an unlocking structure for driving the lock block to disengage from the lock groove. The elastic locking member can keep the cylinder cover in a closed position without the need for manual pressing posture, thus saving manpower.

[0013] As a further improvement, the unlocking structure includes a pull rope connected to the locking block, and the pull rope is used to pull the locking block.

[0014] As a further improvement, the handle comprises a vertical rod and a horizontal rod arranged at the top of the vertical rod, and the top of the vertical rod is provided with a reduced diameter section to form a first upward step; The pulling structure includes an unlocking rod and an unlocking rod spring which are sleeved outside the reduced diameter section. The unlocking rod spring is pressed between the unlocking rod and the cross bar to press the unlocking rod onto the second step. The unlocking rod is connected to the pull rope.

[0015] As a further improvement, the bottom of the cylinder cover slide groove extends to the outside of the cylinder body, so that the pin shaft can push the soil in the cylinder cover slide groove to the outside of the cylinder body.

[0016] As a further improvement, the force-applying seat includes second foot pedals disposed on both sides of the handle, and the second foot pedals are for people to step on to apply force.

[0017] As a further improvement, the cylinder body includes two C-shaped plates buckled together along the left and right directions, wherein the front side of one of the C-shaped plates is provided with a plug plate extending left and right, and the front side of the other C-shaped plate is correspondingly provided with a slot, and the plug plate is adapted to be inserted into the slot, and the sampling cylinder structure also includes a fixed seat, and the two C-shaped plates are slidably assembled on the fixed seat along the left and right directions, and each C-shaped plate is provided with a guide plate that penetrates the fixed seat upward, and the guide plate is slidably assembled on the fixed seat along the left and right directions, and the fixed seat is also provided with an elastic clamping component for applying an elastic force to the two guide plates to bring the two C-shaped plates closer to each other; The horizontal plate is provided with a top pressure plate, and the top pressure plate and the sealing plate are arranged on the front and rear sides of the horizontal plate. The top pressure plate and the sealing plate are provided with inclined surfaces on the left and right sides of the bottom, and the inclined surfaces are used to press the guide plate downward to make the two guide plates move back to back. When sampling soft soil, by applying force downward to the force-applying seat, the two C-shaped plates can be pushed back to back through the inclined surface, expanding the space volume formed by the square sampling tube and the tube cover. When the crushing structure crushes the soil sample, the soil sample has more space to roll, reducing the resistance of the crushing structure to rotate.

[0018] The beneficial effects are: 1. When in use, the cylinder cover is first in the open position, the cylinder cover and the sealing plate jointly close the rear opening of the cylinder, the square sampling cylinder is inserted into the soil, and the soil sample enters the space surrounded by the cylinder, the cylinder cover and the sealing plate. The operator then applies force downward to the force-applying seat, and the force-applying seat pushes the horizontal plate and the sealing plate downward, and the sealing plate pushes the cylinder cover downward. The cylinder cover slides obliquely downward to gradually close the bottom opening of the cylinder, and at the same time cuts off the connection between the soil sample and the external soil. The sealing plate alone closes the rear opening of the cylinder. At this time, the bottom of the cylinder is closed, the crushing rod in the crushing structure rotates, and the crushing blades crush the lumps in the soil sample. In the soil sampling and testing device for land reclamation of the present invention, the bottom surface of the square sampling cylinder is an inclined surface, which is convenient for inserting into the soil. By setting a slidable cylinder cover, on the one hand, it can cut off the connection between the soil sample and the external soil; on the other hand, it can form a closed space together with the square sampling cylinder when the crushing structure rotates and crushes, so that the crushing structure can fully crush the soil sample in the space, improve the crushing effect, and avoid the problems of low efficiency and hand fatigue caused by manual hand-kneading. Since the cylinder cover closes the bottom opening of the square sampling cylinder, when the crushing is completed and the soil sample is pulled out of the soil, the crushed soil sample will not fall out of the square sampling cylinder, and the sampling can be carried out smoothly.

[0019] 2. Through the cooperation of the spiral groove and the sliding protrusion, the breaking rod can rotate during the up and down movement; the force seat can not only press the cross plate downward, but also press the breaking rod downward, with more concentrated functions, which is convenient for the staff to operate.

[0020] 3. The breaker bar reset spring can exert an upward force on the breaker bar, making it easier for the breaker bar to reset upward.

[0021] 4. The elastic locking piece can keep the cylinder cover in the closed position, and there is no need to manually maintain the pressing posture, which saves manpower.

[0022] 5. When sampling soft soil, by applying downward force to the force-applying seat, the two C-shaped plates can be pushed toward each other through the inclined surface, thereby expanding the space volume formed by the square sampling tube and the tube cover. When the crushing structure crushes the soil sample, the soil sample has more space to roll, reducing the resistance to the rotation of the crushing structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] An embodiment of a soil sampling and testing device for land reclamation provided by the present invention: like Figures 1 to 24 As shown, the soil sampling device for land reclamation of this embodiment is suitable for sampling loose soil, which is usually one or more of sandy soil, sandy loam, humus soil, and peat soil. Although the soil is loose, it is found in actual operation that due to the influence of external factors and microbial activities, soil particles are easily bonded together to form lumps.

[0027] A soil sampling device for land reclamation (hereinafter referred to as the soil sampling device) includes a sampling tube structure 100, a handle 200, an unlocking structure 300, a crushing structure 400, and a force-applying structure 500. The handle 200 is installed on the top of the sampling tube structure 100.

[0028] like Figures 1 to 19 As shown, the sampling tube structure 100 includes a fixing seat 101, a square sampling tube 102, a tube cover 103, an elastic clamping component, an elastic locking component, and a sealing plate reset spring 104. The square sampling tube 102 is installed at the bottom of the fixing seat 101, and the tube cover 103 is installed on the square sampling tube 102.

[0029] Specifically, the fixing base 101 includes a fixing plate 105 and two first foot pedals 106 fixed on opposite sides of the fixing plate 105. For the convenience of description, the two first foot pedals 106 are defined as being located on the left and right sides of the fixing plate 105, and the first foot pedals 106 extend from the fixing plate 105 to the left and right sides for people to step on, thereby applying a downward force to the fixing plate 105 and the square sampling cylinder 102, so that the bottom of the square sampling cylinder 102 can be inserted into the soil.

[0030] The fixing plate 105 is provided with a guide plate through hole 107 and a sealing plate through hole 108 that penetrate the fixing plate 105 in the up-down direction, wherein there are two guide plate through holes 107, which are located on the left and right sides of the fixing plate 105, and the sealing plate through hole 108 is located on the rear side of the fixing plate 105. A slide groove 109 extending left and right is provided at the bottom of the fixing plate 105, and the slide groove 109 allows the square sampling tube 102 to slide in the left-right direction.

[0031] The horizontal cross-section of the square sampling tube 102 is a quadrilateral, and its bottom surface 110 is an inclined surface arranged obliquely in the front-to-back direction. Here, the lower side of the bottom surface 110 is defined as the front side, and the higher side is defined as the rear side. The bottom surface 110 of the square sampling tube 102 is generally lower in the front and higher in the rear.

[0032] The square sampling cylinder 102 includes a cylinder body 111 , a sliding seat 112 , and a guide plate 113 . The guide plate 113 is fixedly mounted on the top of the cylinder body 111 .

[0033] Specifically, the bottom of the cylinder 111 is provided with a bottom opening, the rear side is provided with a rear opening, and the left and right sides of the cylinder 111 are provided with a sealing plate chute 114 and a cylinder cover chute 115, wherein the sealing plate chute 114 is provided at the rear opening and extends in the up-down direction, and the cylinder cover chute 115 is provided at the bottom opening of the cylinder 111, and the inclination direction of the cylinder cover chute 115 is consistent with the inclination direction of the bottom surface 110, and the cylinder cover chute 115 and the bottom surface 110 are parallel to each other. The lower end of the cylinder cover chute 115 is connected to the outside, and the soil in the cylinder cover chute 115 can be pushed out of the cylinder 111.

[0034] A sealing plate through hole 116 is also provided on the top of the rear side of the cylinder 111 , and the sealing plate through hole 116 is communicated with the sealing plate sliding groove 114 .

[0035] Specifically, the cylinder 111 includes two C-shaped plates 117 that are buckled together in the left-right direction. The two C-shaped plates 117 have the same structure. Each C-shaped plate 117 includes a first side plate 118 located on the front side, a second side plate 119 located on the rear side, and a connecting plate connecting the first side plate 118 and the second side plate 119. It should be noted that the C-shaped plate 117 is an integrated structure, and the components are artificially split and defined only for the convenience of description.

[0036] A plug plate 120 extending left and right is provided on the first side plate 118 of the left C-shaped plate 117, and a slot 121 extending left and right is provided on the first side plate 118 of the right C-shaped plate 117. The plug plate 120 is adaptively inserted into the slot 121, and the slot 121 and the plug plate 120 have a certain length in the left and right direction, so that the two C-shaped plates 117 can move a certain distance away from each other without separating.

[0037] The inner sides of the two C-shaped plates 117 are provided with the above-mentioned sealing plate slide groove 114 and the cylinder cover slide groove 115, and the opposite sides of the second side plates 119 of the two C-shaped plates 117 are provided with U-shaped grooves 122. The U-shaped grooves 122 of the two C-shaped plates 117 are spliced ​​to form the above-mentioned sealing plate through hole 116.

[0038] The top of the C-shaped plate 117 is slidably assembled in the slide groove 109 at the bottom of the fixed plate 105 along the left-right direction. It should be noted that in order to ensure that the C-shaped plate 117 and the fixed plate 105 can move synchronously in the up-down direction, in actual use, a dovetail groove, a T-shaped groove and other structures can be set on the groove wall of the slide groove 109, and a slider adapted to the dovetail groove and the T-shaped groove can be set on the C-shaped plate 117, thereby ensuring that the C-shaped plate 117 and the fixed plate 105 can move relative to each other in the horizontal direction and can be relatively fixed in the up-down direction. Among them, the use of dovetail grooves, T-shaped grooves and sliders adapted thereto to achieve the above functions belongs to common sense in the field and will not be repeated here.

[0039] There are two guide plates 113, and the two guide plates 113 correspond to the two C-shaped plates 117 one by one. The guide plates 113 are fixed to the top of the C-shaped plates 117, and can be fixed by welding. The guide plates 113 pass through the guide plate through holes 107 on the fixing plate 105 from top to bottom. In the left-right direction, the thickness of the guide plates 113 is less than the width of the guide plate through holes 107, so that the guide plates 113 can move in the left-right direction.

[0040] like Fig.18 As shown, the sliding seat 112 includes a sealing plate 123, a horizontal plate 124 fixed on the top of the sealing plate 123, and a top pressure plate 125 fixed on the horizontal plate 124. The sealing plate 123 is slidably assembled in the sealing plate through hole 116 and the sealing plate slide groove 114, and can slide up and down. The sealing plate 123 is used to close the rear opening of the cylinder body 111 alone or together with the cylinder cover 103. The upper end of the sealing plate 123 passes upward through the sealing plate through hole 108 on the fixed plate 105. The horizontal plate 124 is sleeved on the outside of the handle 200, and the top pressure plate 125 is fixed on the bottom of the horizontal plate 124. The top pressure plate 125 and the sealing plate 123 are located on the front and rear sides of the handle 200, and the top pressure plate 125 and the sealing plate 123 are parallel to each other. The sealing plate 123 and the pressing plate 125 have downwardly facing inclined surfaces 126 on both sides. The inclined surfaces 126 are inclined from bottom to top and away from each other. The inclined surfaces 126 are used to press the guide plate 113 downward.

[0041] A locking member receiving groove 127 is formed on the inner side of the transverse plate 124 for receiving the elastic locking member. A drawstring through hole 128 is also formed on the transverse plate 124 , and the drawstring through hole 128 is communicated with the locking member receiving groove 127 .

[0042] The top of the cylinder cover 103 is hinged to the bottom of the sealing plate 123. A pin 129 is fixed to the bottom of the cylinder cover 103. The two ends of the pin 129 are located outside the cylinder cover 103. The two ends of the pin 129 are respectively slidably assembled in the cylinder cover slide groove 115. The width of the cylinder cover 103 is greater than the width of the sealing plate 123. When the sealing plate 123 moves upward, it drives the cylinder cover 103 to slide upward, and the bottom opening of the cylinder body 111 is opened. The sealing plate 123 and the cylinder cover 103 together close the rear opening of the cylinder body 111. At this time, the cylinder cover 103 is in the open position. When the sealing plate 123 moves downward, it drives the cylinder cover 103 to slide obliquely downward, closing the bottom opening of the cylinder body 111. The sealing plate 123 alone closes the rear opening of the cylinder body 111.

[0043] like Fig.12 As shown, the elastic locking member includes a locking block 130 and a locking block spring 131. Specifically, the locking block 130 is accommodated in the locking member accommodating groove 127. The locking block spring 131 is a compression spring, one end of which is connected to the bottom of the locking member accommodating groove 127 and the other end is connected to the locking block 130. The locking block spring 131 can push the locking block 130 out of the locking member accommodating groove, and can also retract into the locking member accommodating groove 127 when the locking block 130 is subjected to a pulling force.

[0044] The function of the elastic clamping component is to drive the two C-shaped plates 117 to move closer to each other. The elastic clamping component includes a spring mounting seat 132 and a clamping spring 133. Specifically, there are two spring mounting seats 132 and two clamping springs 133, and they correspond to the two C-shaped plates 117 one by one. The spring mounting seat 132 is integrally formed on the first foot pedal 106. The clamping spring 133 here is a compression spring. One end of the clamping spring 133 is fixed on the spring mounting seat 132, and the other end is fixed on the guide plate 113. When the guide plate 113 is pressed by the inclined surface 126 of the sealing plate 123 and the top pressure plate 125, the two guide plates 113 overcome the force of the clamping spring 133 and separate from each other; when the sealing plate 123 moves upward, the two guide plates 113 move closer to each other under the action of the clamping spring 133, so that the two C-shaped plates 117 are closed together.

[0045] The sealing plate return spring 104 is a compression spring, which is sleeved on the outside of the handle 200, and the bottom of the sealing plate return spring 104 is fixed on the fixing plate 105, and the upper end is fixed on the transverse plate 124. The sealing plate return spring 104 applies an upward elastic force to the transverse plate 124. When the locking block 130 retracts into the locking member receiving groove 127, the sealing plate return spring 104 pushes the transverse plate 124 and the sealing plate 123 upward.

[0046] like Figures 2 to 5 as well as Fig. 20 , Fig.21As shown, the handle 200 is fixedly mounted on the top of the fixing plate 105, and the handle 200 includes a vertical rod and a horizontal rod 203 fixed on the top of the vertical rod. The vertical rod includes a first vertical rod 201 and a second vertical rod 202. The horizontal rod 203 is fixed to the upper end of the first vertical rod 201, and the second vertical rod 202 is fixed to the fixing plate 105. The first vertical rod 201 and the second vertical rod 202 are separately processed and then assembled together, and can be specifically connected by threaded connection or the like.

[0047] The bottom surface of the second vertical rod 202 is provided with a crushing rod through hole 204 extending upward, and the rear side of the second vertical rod 202 is provided with an escape groove 205 connected to the crushing rod through hole 204, and the escape groove 205 extends up and down. The hole wall of the crushing rod through hole 204 is provided with a spiral groove 206 extending up and down. The front side of the second vertical rod 202 is provided with a locking groove 208, which is located below the escape groove 205. The function of the locking groove 208 is to allow the locking block 130 to extend into it. When the locking block 130 extends into the locking groove 208, the horizontal plate 124 cannot move up and down relative to the handle 200. The top of the first vertical rod 201 has a reduced diameter section, thereby forming a first step 207 facing upward.

[0048] like Figures 1 to 5 As shown, the unlocking structure 300 is used to pull the lock block 130 so that the lock block 130 is disengaged from the lock slot 208. The unlocking structure 300 includes an unlocking rod 301, an unlocking rod spring 302, and a pull rope 303. The unlocking rod 301 is sleeved on the first vertical rod 201, specifically, on the reduced diameter section of the first vertical rod 201. The unlocking rod spring 302 is a compression spring, the upper end of the unlocking rod spring 302 presses on the cross bar 203, and the lower end presses on the unlocking rod 301, so that the unlocking rod 301 is pressed on the first step 207. One end of the pull rope 303 is fixed on the unlocking rod 301, and the other end is fixed on the locking block 130, wherein the length of the pull rope 303 satisfies the following conditions: when the locking block 130 is inserted into the locking groove 208 outside the handle 200, the pull rope 303 is in a straight state or has a small redundancy; after the unlocking rod 301 is pulled upward, the unlocking rod 301 drives the pull rope 303 to pull the locking block 130 out of the locking groove 208.

[0049] like Figures 1 to 4 as well as Fig.21 , Fig. 22 As shown, the crushing structure 400 includes a crushing rod 401, a crushing blade 402, a crushing rod return spring 403, and a sliding protrusion 404. The crushing rod 401 extends up and down, including a crushing rod small diameter section at the bottom and a crushing rod large diameter section at the top. The crushing rod small diameter section and the crushing rod large diameter section form a second downward step 405. The crushing rod large diameter section upwardly penetrates into the crushing rod through hole 204, and the top surface of the crushing rod large diameter section is located at the height of the avoidance groove 205; the crushing rod small diameter section downwardly passes through the fixing plate 105 and penetrates into the square sampling tube 102.

[0050] The crushing blades 402 are fixed on the part of the crushing rod small diameter section located in the square sampling tube 102. The crushing blades 402 extend from the crushing rod small diameter section toward the tube wall of the square sampling tube 102. When the crushing rod 401 rotates, it can crush the soil in the square sampling tube 102. There are multiple crushing blades 402, and the multiple crushing blades 402 are arranged at intervals in the up and down directions.

[0051] The breaker rod reset spring 403 is sleeved on the outside of the small diameter section of the breaker rod, with the lower end fixed on the fixed plate 105 and the upper end against the second step 405. Specifically, in order to prevent the breaker rod reset spring 403 from twisting when the breaker rod 401 rotates relative to the fixed plate 105, a gasket can be arranged between the breaker rod reset spring 403 and the second step 405.

[0052] The sliding protrusion 404 is fixed to the outside of the large diameter section of the breaker rod, and the sliding protrusion 404 extends into the spiral groove 206 and can slide in the spiral groove 206, so that the breaker rod 401 can rotate while moving up and down relative to the handle 200. Preferably, the sliding protrusion 404 is a hemispherical protrusion.

[0053] like Fig.24 As shown, the function of the force-applying structure 500 is to apply force downward to the horizontal plate 124 and the crushing rod 401. The force-applying structure 500 includes a force-applying seat 501 and a pressing protrusion 502. The force-applying seat 501 is sleeved on the handle, and the pressing protrusion 502 is fixed on the inner side of the force-applying seat 501. The force-applying seat 501 includes two second foot pedals 503 arranged opposite to each other on the left and right for people to step on. The pressing protrusion 502 is located in the avoidance groove 205 and is used to push the crushing rod 401 downward. During assembly, after the force-applying structure 500 is installed on the second vertical rod 202, the first vertical rod 201 is fixed on the second vertical rod 202. In other embodiments, the first vertical rod 201 and the second vertical rod 202 can be an integrated structure, and the pressing protrusion 502 and the force seat 501 are separately fixed together. After the pressing protrusion 502 is inserted into the avoidance groove 205 and the force seat 501 is put on the handle 200, the pressing protrusion 502 and the force seat 501 are fixed together.

[0054] Usage process: In the initial state, the closing plate reset spring 104 pushes the horizontal plate 124 upward, and pulls the cylinder cover 103 upward through the closing plate 123, so that the cylinder cover 103 is in the open position. At this time, the top surface of the horizontal plate 124 is located above the top surface of the breaking rod 401. The elastic clamping component drives the two C-shaped plates 117 to move closer to each other, and the unlocking rod 301 is pressed against the first step 207 by the unlocking rod spring 302.

[0055] The staff holds the handle 200 and inserts the bottom of the square sampling tube 102 into the soil. The staff can step on the first foot pedal 106 for assistance. During the insertion process, the soil sample enters the square sampling tube 102. After the insertion reaches the set depth, the staff steps on the second foot pedal 503 to apply force to the horizontal plate 124. The horizontal plate 124 drives the tube cover 103 to slide downward through the sealing plate 123. During the downward sliding process of the tube cover 103, the bottom of the square sampling tube 102 is gradually closed and the connection between the soil sample and the external soil is cut off. When the locking block 130 is inserted into the locking groove 208, the horizontal plate 124 moves down to the limit position.

[0056] During the downward movement of the horizontal plate 124, the inclined surfaces 126 on the sealing plate 123 and the pressing plate 125 press the guide plate 113, causing the two C-shaped plates 117 to move in opposite directions, thereby increasing the space in the square sampling tube 102 and facilitating subsequent crushing. During the downward movement of the force-applying seat 501, the pressing protrusion 502 presses the crushing rod 401, causing the crushing rod 401 to move downward. During the downward movement of the crushing rod 401, the crushing rod 401 rotates with the cooperation of the spiral groove 206 and the sliding protrusion 404, driving the crushing rod 401 and the crushing blade 402 to rotate and move downward, thereby crushing the soil sample in the square sampling tube 102. During this process, the tube cover 103 closes the square sampling tube 102, and the soil sample will not escape from the square sampling tube 102. After the downward pressure on the force-applying seat 501 is removed, the breaker bar reset spring 403 drives the breaker bar 401 to move upward, and rotates again during the upward movement. After the breaker bar 401 moves up and down multiple times, the lumps in the soil sample can be broken into required particles. It should be noted that during the initial crushing, if the elastic force of the breaker bar reset spring 403 is insufficient to drive the breaker bar 401 to move upward, the staff can lift up the second foot pedal 503 to apply force upward.

[0057] It should be noted that in actual use, when the top pressure plate 125 and the sealing plate 123 move downward and press the guide plate 113, the upper ends of the two C-shaped plates 117 are subjected to greater force. If the soil is not soft enough, the upper ends of the two C-shaped plates 117 will separate from each other but the lower ends will remain closed. However, this situation can still expand the volume of the space surrounded by the square sampling tube 102 and the tube cover 103. After the two C-shaped plates 117 move back to back, since the sealing plate 123 is inserted into the U-shaped groove 122 and the sealing plate slide 114 to a certain depth, the two C-shaped plates 117 rely on the cooperation of the plug plate 120 and the slot 121, and the cooperation of the sealing plate 123 with the two U-shaped grooves 122 and the sealing plate slide 114, it can ensure that the soil sample does not leak out.

[0058] It should be noted that after the two C-shaped plates 117 move away from each other, the soil sample will inevitably enter the gap formed by the two C-shaped plates 117. However, since the amount of movement of the two C-shaped plates 117 away from each other is small, the amount of soil sample that enters is small. The soil sample can be shaken out later by bumping or the like, or it can be cleaned after several sampling intervals.

[0059] In this embodiment, the cylinder 111 includes two C-shaped plates 117 that are buckled together in the left-right direction. An elastic clamping component is provided on the fixed seat 101 to apply elastic force to the two C-shaped plates 117. At the same time, an inclined surface 126 is provided at the bottom of the top pressure plate 125 and the sealing plate 123 to push the guide plate 113. In other embodiments, if the soil is not soft enough, it is difficult for the two C-shaped plates 117 to separate in opposite directions in the soil. In this case, the cylinder 111 is designed as an integrated structure, and the elastic clamping component, the top pressure plate 125, the inclined surface 126 and other structures can be eliminated.

[0060] In this embodiment, the unlocking structure 300 includes an unlocking rod 301, an unlocking rod spring 302, and a pull rope 303. In other embodiments, the unlocking rod 301 and the unlocking rod spring 302 can be eliminated, and only the pull rope 303 is retained. In other embodiments, the unlocking structure 300 can be a handle set on the horizontal plate 124, and the handle is connected to the locking block 130. By pulling the handle, the locking block 130 is disengaged from the locking groove 208.

[0061] In this embodiment, the cylinder cover 103 is kept in the closed position by the elastic locking member, and the cylinder cover 103 is driven from the closed position to the open position by the sealing plate reset spring 104. In other embodiments, a row of pin holes arranged at intervals in the vertical direction are provided on the handle 200. When the cylinder cover 103 is in the closed position, a latch is inserted into the corresponding pin hole, and the latch cooperates with the horizontal plate 124 to prevent the horizontal plate 124 and the sealing plate 123 from moving upward.

[0062] In this embodiment, a sliding protrusion 404 is provided on the breaker bar 401, and a spiral groove 206 is provided on the hole wall of the breaker bar through hole 204. When the breaker bar 401 moves downward, the breaker bar 401 is driven to rotate by the cooperation of the sliding protrusion 404 and the spiral groove 206. In other embodiments, the sliding protrusion 404 can be provided on the hole wall of the breaker bar through hole 204, and the spiral groove 206 is provided on the outside of the breaker bar 401. In other embodiments, a threaded hole that passes through the handle 200 is provided vertically, the breaker bar 401 passes through the handle, the breaker bar 401 and the handle 200 are threadedly matched, the upper end of the breaker bar 401 is located above the handle 200, and the breaker bar 401 is driven to rotate and move up and down by rotating the breaker bar 401.

[0063] In addition, in the description of this specification, “plurality” means at least two, for example, two, three or more, etc., unless otherwise clearly and specifically defined.
