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 consolidation refers to the consolidation of inefficiently used, irrationally used, and unused land. In the process of land consolidation, 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 consolidation 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 carries the soil sample up. 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] To address the inconvenience of manually digging soil samples out of a sampling tube in the prior art, a utility model patent with authorization publication number CN218916864U discloses a device capable of sampling in frozen soil areas. The device comprises a sampling tube, a push rod, and a push head. The sampling tube is internally provided with an internally threaded ring, the push rod is threadedly assembled on the internally threaded ring, and the push head is mounted on the push rod. During use, the sampling tube is inserted into the soil and the soil sample is removed. The push rod is rotated, which drives the push head toward the sampling port at the bottom of the sampling tube. The push head pushes the soil sample out of the sampling tube, eliminating the need for manual digging of 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. Manual crushing of soil samples is inefficient and easily causes hand fatigue, which brings inconvenience to the sampling work. Summary of the Invention

[0006] The present invention provides a soil sampling and testing device for land reclamation, which solves the technical problem in the prior art that lumps in soil samples need to be manually crushed, causing inconvenience to the sampling work.

[0007] To solve the above problems, the present invention provides a soil sampling and testing device for land reclamation, which adopts the following technical solutions: a soil sampling and testing device for land reclamation, comprising a sampling tube structure, a handle provided on the top of the sampling tube structure, a crushing structure, and a force-applying structure;

[0008] The sampling cylinder structure includes a square sampling cylinder and a cylinder cover. The bottom of the square sampling cylinder is low in front and high in the back and is arranged inclinedly. The square sampling cylinder includes a cylinder body and a sealing plate. The cylinder 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 directions to close the rear opening. The upper end of the sealing plate extends to the top of the cylinder body, and the top of the sealing plate is provided with a horizontal plate that slides up and down on the handle; cylinder cover sliding grooves are provided on the left and right sides of the inside of the cylinder body at the bottom opening, and the cylinder cover sliding grooves are arranged parallel to the bottom surface of the square sampling cylinder; the left and right sides of the bottom of the cylinder cover are slidably assembled in the cylinder cover sliding grooves by pin shafts, and the top of the cylinder cover is connected to the bottom of the sealing plate so that the sealing plate drives the cylinder cover to slide reciprocally, and the sliding stroke of the cylinder cover has a closed position that closes the bottom opening, and also has a free position that opens the bottom opening and jointly closes the rear opening with the sealing plate;

[0009] The crushing structure includes a crushing rod assembled 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 in the up and down directions, and the force-applying seat is used to apply downward force to the horizontal plate.

[0010] During use, the cylinder cover is first in the out-of-the-way position, and the cylinder cover and the sealing plate jointly seal 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, which pushes the cross 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, while cutting off the connection between the soil sample and the external soil. The sealing plate alone seals 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 insertion into the soil. By providing 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, thereby improving the crushing effect and avoiding 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 sampling can be carried out smoothly.

[0011] 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;

[0012] 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;

[0013] The force applying seat is provided with a pressing protrusion which passes through the avoidance groove and presses the crushing rod downwards;

[0014] The crushing mechanism also includes a breaker bar return spring that applies upward force to the breaker bar. The spiral groove and sliding protrusions allow the breaker bar to rotate as it moves up and down. The force-applying seat pushes down both the cross plate and the breaker bar, concentrating functions and facilitating operation.

[0015] 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 downward step, and the breaker rod small diameter section penetrates downward into the square sampling tube;

[0016] 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, making it easy for the breaker rod to reset upward.

[0017] As a further improvement, the sampling tube structure also includes a sealing plate reset spring mounted 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.

[0018] 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 to keep the cylinder cover in the closed position;

[0019] The soil sampling and testing device for land reclamation also includes an unlocking structure for driving the locking block to disengage from the locking groove. The elastic locking member can keep the cylinder cover in the closed position without the need for manual pressing posture, thus saving manpower.

[0020] 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.

[0021] As a further improvement, the handle includes a vertical rod and a horizontal rod provided on 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;

[0022] 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.

[0023] As a further improvement, the bottom of the cylinder cover chute extends to the outside of the cylinder body, so that the pin shaft can push the soil in the cylinder cover chute to the outside of the cylinder body.

[0024] 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.

[0025] As a further improvement, the barrel includes two C-shaped plates that are buckled together in the left and right directions, wherein the front side of one of the C-shaped plates is provided with an insert plate extending left and right, and the front side of the other C-shaped plate is correspondingly provided with a slot, and the insert plate is adapted to be inserted into the slot. The sampling barrel structure also includes a fixed seat, and the two C-shaped plates are slidably assembled on the fixed seat in the left and right directions. 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 in the left and right directions. 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;

[0026] The horizontal plate is provided with a pressure plate, which is located at the front and rear of the horizontal plate, and a sealing plate. Both the pressure plate and the sealing plate have inclined surfaces on their left and right sides, which are used to press the guide plates downward, causing them to move away from each other. When sampling soft soil, downward force is applied to the force-applying seat, which pushes the two C-shaped plates toward each other via the inclined surfaces. This expands the volume of the space enclosed by the square sampling tube and the tube cover. This allows the soil sample to roll more freely during crushing, reducing the resistance to the crushing structure's rotation.

[0027] The beneficial effects are:

[0028] 1. When in use, the cylinder cover is first in the out-of-the-way position, and the cylinder cover and the sealing plate jointly seal the rear opening of the cylinder body. The square sampling cylinder is inserted into the soil, and the soil sample enters the space surrounded by the cylinder body, 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 body, and at the same time cuts off the connection between the soil sample and the external soil. The sealing plate alone seals the rear opening of the cylinder body. At this time, the bottom of the cylinder body is closed, and 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 insertion into the soil. By providing 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, thereby improving the crushing effect and avoiding 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 sampling can be carried out smoothly.

[0029] 2. Through the cooperation of the spiral groove and the sliding protrusion, the breaker bar can rotate during the up and down movement; the force seat can not only press down the cross plate, but also press down the breaker bar, which makes the functions more centralized and convenient for the staff to operate.

[0030] 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.

[0031] 4. The elastic locking piece can keep the cylinder cover in the closed position, without the need for manual pressing posture, saving manpower.

[0032] 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

[0064] The following will be combined with the accompanying 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0065] An embodiment of a soil sampling and testing device for land reclamation provided by the present invention:

[0066] 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 typically one or more of sand, sandy loam, humus, and peat. Although the soil is loose, in actual operation, it has been found that due to external factors and microbial activity, soil particles tend to stick together and form lumps.

[0067] A soil sampling and testing device for land reclamation (hereinafter referred to as the soil sampling and testing 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.

[0068] like Figures 1 to 19 As shown, the sampling cylinder structure 100 includes a fixing seat 101, a square sampling cylinder 102, a cylinder cover 103, an elastic clamping component, an elastic locking component, and a sealing plate reset spring 104. The square sampling cylinder 102 is installed at the bottom of the fixing seat 101, and the cylinder cover 103 is installed on the square sampling cylinder 102.

[0069] Specifically, the fixing base 101 includes a fixing plate 105 and two first footrests 106 fixed on opposite sides of the fixing plate 105. For ease of description, the two first footrests 106 are defined as being located on the left and right sides of the fixing plate 105. The first footrests 106 extend from the fixing plate 105 to the left and right sides, allowing a person to step on them, thereby applying a downward force to the fixing plate 105 and the square sampling cylinder 102, allowing the bottom of the square sampling cylinder 102 to be inserted into the soil.

[0070] The fixing plate 105 is provided with a guide plate through-hole 107 and a sealing plate through-hole 108 that extend vertically through the fixing plate 105. There are two guide plate through-holes 107, one on each side of the fixing plate 105, and the other on the rear side of the fixing plate 105. A sliding groove 109 extending horizontally is provided at the bottom of the fixing plate 105, through which the square sampling cartridge 102 slides horizontally.

[0071] The horizontal cross-section of the square sampling tube 102 is a quadrilateral, and its bottom surface 110 is an inclined surface arranged in a 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.

[0072] 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 .

[0073] 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 interior of the cylinder 111 are provided with a sealing plate chute 114 and a cylinder cover chute 115. Among them, the sealing plate chute 114 is provided at the rear opening and extends in the vertical direction, and the cylinder cover chute 115 is provided at the bottom opening of the cylinder 111. 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. Among them, 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.

[0074] A sealing plate through hole 116 is further 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 .

[0075] Specifically, the cylinder 111 includes two C-shaped plates 117 that are interlocked 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.

[0076] The first side plate 118 of the left C-shaped plate 117 is provided with an insert plate 120 extending left and right, and the first side plate 118 of the right C-shaped plate 117 is provided with a slot 121 extending left and right. The insert plate 120 is adaptively inserted into the slot 121, and the slot 121 and the insert plate 120 both have a certain length in the left and right directions, so that the two C-shaped plates 117 can move a certain distance away from each other without separating.

[0077] The inner sides of the two C-shaped plates 117 are provided with the above-mentioned sealing plate slide groove 114 and 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 together to form the above-mentioned sealing plate through hole 116.

[0078] The top of the C-shaped plate 117 slides horizontally into the chute 109 at the bottom of the fixed plate 105. It should be noted that to ensure that the C-shaped plate 117 and the fixed plate 105 can move synchronously in the vertical direction, in actual use, dovetail grooves, T-shaped grooves, or other structures can be provided on the walls of the chute 109, and sliders adapted to the dovetail grooves and T-shaped grooves can be provided on the C-shaped plate 117. This ensures 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 vertical direction. The use of dovetail grooves, T-shaped grooves, and corresponding sliders to achieve the above-mentioned functions is common knowledge in the art and will not be elaborated upon here.

[0079] There are two guide plates 113, one corresponding to each of the two C-shaped plates 117. The guide plates 113 are fixed to the tops of the C-shaped plates 117, specifically by welding. The guide plates 113 extend vertically through the guide plate holes 107 in the fixed plate 105. In the left-right direction, the thickness of the guide plates 113 is less than the width of the guide plate holes 107, allowing them to move in that direction.

[0080] like Figure 18As shown, the sliding seat 112 includes a sealing plate 123, a horizontal plate 124 fixed to the top of the sealing plate 123, and a top pressure plate 125 fixed to 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 to the bottom of the horizontal plate 124. The top pressure plate 125 and the sealing plate 123 are located on the front and back sides of the handle 200, and the top pressure plate 125 and the sealing plate 123 are parallel to each other. The left and right sides of the sealing plate 123 and the pressing plate 125 are both provided with downwardly facing inclined surfaces 126 . 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.

[0081] A locking member receiving groove 127 is defined on the inner side of the transverse plate 124 for receiving the elastic locking member. A drawstring through hole 128 is also defined on the transverse plate 124 , and the drawstring through hole 128 is communicated with the locking member receiving groove 127 .

[0082] The top of the cylinder cover 103 is hinged to the bottom of the closing 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 115. The width of the cylinder cover 103 is greater than the width of the closing plate 123. When the closing plate 123 moves upward, it drives the cylinder cover 103 to slide upward, opening the bottom opening of the cylinder body 111. The closing 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 closing plate 123 moves downward, it drives the cylinder cover 103 to slide obliquely downward, closing the bottom opening of the cylinder body 111. The closing plate 123 alone closes the rear opening of the cylinder body 111.

[0083] like Figure 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.

[0084] The function of the elastic clamping component is to drive the two C-shaped plates 117 toward 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, each corresponding to one of the two C-shaped plates 117. The spring mounting seat 132 is integrally formed on the first footrest 106. The clamping spring 133 here is a compression spring, with one end of the clamping spring 133 fixed to the spring mounting seat 132 and the other end fixed to the guide plate 113. When the guide plates 113 are pressed by the closing plate 123 and the inclined surface 126 of the pressure plate 125, the two guide plates 113 overcome the force of the clamping spring 133 and separate from each other. When the closing plate 123 moves upward, the two guide plates 113 move toward each other under the action of the clamping spring 133, causing the two C-shaped plates 117 to close together.

[0085] The sealing plate return spring 104 is a compression spring that is sleeved on the outside of the handle 200. The bottom of the sealing plate return spring 104 is fixed to the fixed plate 105, and the upper end is fixed to the cross plate 124. The function of the sealing plate return spring 104 is to apply an upward elastic force to the cross plate 124. When the locking block 130 retracts into the locking member receiving groove 127, the sealing plate return spring 104 pushes the cross plate 124 and the sealing plate 123 upward.

[0086] like Figures 2 to 5 as well as Figure 20 、 Figure 21 As shown, the handle 200 is fixedly mounted on the top of the fixed plate 105. The handle 200 includes a vertical rod and a horizontal rod 203 fixed to 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 fixed 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 means such as threaded connections.

[0087] The bottom surface of the second vertical rod 202 is provided with an upward-extending breaker bar hole 204. A vertically extending escape groove 205 is defined on the rear side of the second vertical rod 202 and communicates with the breaker bar hole 204. The escape groove 205 extends vertically. A spiral groove 206 is defined on the wall of the breaker bar hole 204 and spirals upward. A locking groove 208 is defined on the front side of the second vertical rod 202, located below the escape groove 205. This groove accommodates the locking block 130. Once the locking block 130 is inserted into the locking groove 208, the horizontal plate 124 cannot move up or down relative to the handle 200. The top of the first vertical rod 201 has a reduced diameter section, forming an upward-facing first step 207.

[0088] like Figures 1 to 5As shown, the unlocking structure 300 pulls the locking block 130, disengaging it from the locking slot 208. The unlocking structure 300 includes an unlocking lever 301, an unlocking lever spring 302, and a pull cord 303. The unlocking lever 301 is mounted on the first vertical rod 201, specifically, on the reduced diameter section of the first vertical rod 201. The unlocking lever spring 302 is a compression spring. The upper end of the unlocking lever spring 302 presses against the crossbar 203, while the lower end presses against the unlocking lever 301, pressing the unlocking lever 301 against the first step 207. One end of the pull rope 303 is fixed to the unlocking rod 301 and the other end is fixed to the locking block 130, wherein the length of the pull rope 303 meets the following conditions: when the locking block 130 is inserted into the locking slot 208 outside the handle 200, the pull rope 303 is in a straight state or has a small redundancy; after pulling the unlocking rod 301 upward, the unlocking rod 301 drives the pull rope 303 to pull the locking block 130 out of the locking slot 208.

[0089] like Figures 1 to 4 as well as Figure 21 、 Figure 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 vertically, including a small-diameter crushing rod section at the bottom and a large-diameter crushing rod section at the top. The small-diameter crushing rod section and the large-diameter crushing rod section form a downward-facing second step 405. The large-diameter crushing rod section upwardly penetrates the crushing rod through-hole 204, and the top surface of the large-diameter crushing rod section is located at the height of the avoidance groove 205; the small-diameter crushing rod section downwardly passes through the fixing plate 105 and penetrates the square sampling cylinder 102.

[0090] The crushing blades 402 are fixed on the part of the small diameter section of the crushing rod located in the square sampling cylinder 102. The crushing blades 402 extend from the small diameter section of the crushing rod toward the cylinder wall of the square sampling cylinder 102. When the crushing rod 401 rotates, it can crush the soil in the square sampling cylinder 102. There are multiple crushing blades 402, and the multiple crushing blades 402 are arranged at intervals in the up and down directions.

[0091] The breaker rod return 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 resting on the second step 405. Specifically, in order to prevent the breaker rod return 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 return spring 403 and the second step 405.

[0092] The sliding protrusion 404 is fixed to the outside of the large diameter section of the breaker bar. The sliding protrusion 404 extends into the spiral groove 206 and can slide in the spiral groove 206, so that the breaker bar 401 can rotate while moving up and down relative to the handle 200. Preferably, the sliding protrusion 404 is a hemispherical protrusion.

[0093] like Figure 24 As shown, the force-applying structure 500 is used to apply downward force to the horizontal plate 124 and the breaker bar 401. The force-applying structure 500 includes a force-applying seat 501 and a pressing protrusion 502. The force-applying seat 501 is mounted on the handle, and the pressing protrusion 502 is fixed to the inner side of the force-applying seat 501. The force-applying seat 501 includes two second footrests 503 arranged opposite each other for users to step on. The pressing protrusion 502 is located in the avoidance groove 205 and is used to push the breaker bar 401 downward. During assembly, the force-applying structure 500 is installed on the second vertical rod 202, and then the first vertical rod 201 is fixed to 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 fixed together separately. 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.

[0094] Operation: In the initial state, the sealing plate return spring 104 pushes the horizontal plate 124 upward, pulling the cylinder cover 103 upward through the sealing plate 123, placing the cylinder cover 103 in the open position. At this point, the top surface of the horizontal plate 124 is above the top surface of the breaker bar 401. The elastic clamping component drives the two C-shaped plates 117 toward each other, and the unlocking lever 301 is pressed against the first step 207 by the unlocking lever spring 302.

[0095] The staff member holds the handle 200 and inserts the bottom of the square sampling tube 102 into the soil. The staff member can step on the first foot pedal 106 to assist the insertion process. During the insertion process, the soil sample enters the square sampling tube 102. After the insertion reaches the set depth, the staff member 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. As the tube cover 103 slides downward, it gradually closes the bottom of the square sampling tube 102 and cuts off the connection between the soil sample and the external soil. When the locking block 130 is inserted into the locking slot 208, the horizontal plate 124 moves downward to the limit position.

[0096] As the horizontal plate 124 moves downward, the inclined surfaces 126 on the sealing plate 123 and the pressure plate 125 press against the guide plate 113, causing the two C-shaped plates 117 to move away from each other, thereby increasing the space within the square sampling tube 102 and facilitating subsequent crushing. As the force-applying seat 501 moves downward, the pressure protrusion 502 presses against the crushing rod 401, causing the crushing rod 401 to move downward. During this downward movement, the crushing rod 401 rotates in coordination with the spiral groove 206 and the sliding protrusion 404, driving the crushing rod 401 and the crushing blade 402 to rotate and move downward, crushing the soil sample within the square sampling tube 102. During this process, the tube cover 103 seals the square sampling tube 102, preventing the soil sample from escaping from the square sampling tube 102. After the downward pressure on the force-applying seat 501 is removed, the breaker bar return spring 403 drives the breaker bar 401 upward, rotating again during the upward movement. After repeated up and down movements of the breaker bar 401, the lumps in the soil sample are broken into the desired particles. It should be noted that during the initial crushing process, if the elastic force of the breaker bar return spring 403 is insufficient to drive the breaker bar 401 upward, the staff can lift the second foot pedal 503 to apply upward force.

[0097] It should be noted that in actual use, when the top pressure plate 125 and the sealing plate 123 move downward and press against 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 away from each other while the lower ends will remain closed. However, this situation can still expand the volume of the space enclosed by the square sampling tube 102 and the tube cover 103. After the two C-shaped plates 117 move away from each other, because the sealing plate 123 is inserted into the U-shaped groove 122 and the sealing plate chute 114 to a certain depth, the two C-shaped plates 117 rely on the cooperation of the insert 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 chute 114 to ensure that the soil sample does not leak out.

[0098] 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 entering is small. The soil sample can be shaken out later by bumping or the like, or it can be cleaned after several sampling intervals.

[0099] In this embodiment, the cylinder 111 includes two C-shaped plates 117 that interlock together in the left-right direction. An elastic clamping member is provided on the fixed base 101 to apply elastic force to the two C-shaped plates 117. At the same time, inclined surfaces 126 are provided at the bottoms of the pressure plate 125 and the sealing plate 123 to push against the guide plate 113. In other embodiments, if the soil is not sufficiently soft, it will be more difficult for the two C-shaped plates 117 to separate from each other in the soil. In this case, the cylinder 111 is designed as a one-piece structure, and the elastic clamping member, pressure plate 125, inclined surface 126, and other structures can be eliminated.

[0100] In this embodiment, the unlocking mechanism 300 includes an unlocking lever 301, an unlocking lever spring 302, and a pull cord 303. In other embodiments, the unlocking lever 301 and unlocking lever spring 302 may be eliminated, leaving only the pull cord 303. In other embodiments, the unlocking mechanism 300 may be a handle disposed on the horizontal plate 124, connected to the locking block 130. Pulling the handle disengages the locking block 130 from the locking slot 208.

[0101] In this embodiment, the cylinder cover 103 is maintained in the closed position by an elastic locking member, and is driven from the closed position to the open position by the closing plate return spring 104. In other embodiments, a row of pin holes spaced apart 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 engages with the horizontal plate 124 to prevent the horizontal plate 124 and the closing plate 123 from moving upward.

[0102] In this embodiment, a sliding protrusion 404 is provided on the breaker bar 401, and a spiral groove 206 is provided on the wall of the breaker bar through-hole 204. When the breaker bar 401 moves downward, the sliding protrusion 404 and the spiral groove 206 cooperate to drive the breaker bar 401 to rotate. In other embodiments, the sliding protrusion 404 can be provided on the wall of the breaker bar through-hole 204, and the spiral groove 206 can be provided on the exterior of the breaker bar 401. In other embodiments, a threaded hole is provided in the handle 200 that passes through the handle, and the breaker bar 401 is threadedly engaged with the handle 200. The upper end of the breaker bar 401 is located above the handle 200. The breaker bar 401 is driven to rotate and move up and down by rotating the breaker bar 401.

[0103] In addition, in the description of this specification, “a plurality of” means at least two, for example, two, three or more, etc., unless otherwise clearly and specifically defined.
