Description

Technical Field

[0001] The invention belongs to the technical field of soil specimens, and in particular relates to a device for collecting whole-section cross-section specimens of southern red soil. Background Art

[0002] Southern red soil is widely distributed in Zhejiang, Jiangxi, Hunan and northern Guangdong. It is a type of soil formed under the influence of subtropical climate and evergreen broad-leaved forest. Rainwater has long soaked and washed away and dissolved some water-soluble salts, thus forming this soil. It is usually considered to be a poor soil. Therefore, research on red soil can provide guidance for the planting of corresponding crops based on soil characteristics.

[0003] Soil research begins with sampling. The current method for soil sampling is: first, after selecting a sampling location, dig a pit foundation of about 1m3, then repair a protruding cubic soil block structure on the pit wall, then buckle the sample box on the soil block, shovel the soil block off, and then put the soil into the sample box. Although this sampling method is simple, it also has some problems. First, the soil profile structure is a very important indicator in the soil research process, but the traditional sampling method can easily cause the profile to be damaged. Unlike ordinary soil, the surface soil of the red soil layer is very loose. During the sampling process, it is easy to cause the upper soil to scatter and fail to maintain an effective soil structure. At the same time, the soil shoveled off the upper layer can easily exert an outward impact force on the sample box, resulting in the sample box being pushed outward the further the soil is shoveled, resulting in large differences in the structure of the soil samples taken.

[0004] Therefore, based on the above problems, a specimen collection device suitable for southern red soil is proposed to protect the sampled samples while reducing human labor and improving work efficiency. Summary of the Invention

[0005] In response to the above problems, the present invention provides a southern red soil whole section sample collection device, which is used to solve the problem that when sampling red soil, the red soil easily generates thrust on the sampling box, the sampling box is placed unstable, and the sampled soil structure is incomplete and the quality is poor.

[0006] To achieve the above object, the technical solution adopted by the present invention is: A southern red soil whole section profile specimen collection device comprises a bracket, a sample box is slidably arranged in the bracket, and a limiter is detachably provided on the bracket for fixing the sample box on the bracket so as to buckle the soil sample block; A support piece is detachably provided on one side of the bracket, one end of which can be inserted into the bottom of the foundation pit and support the bracket so that the sample box and the soil sample block are fully engaged.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: by adopting a bracket, the sample box can be easily pushed out and buckled with the soil sample block, and after the limit member is inserted, the sample box can be prevented from retreating, thereby ensuring that the sample box completely buckles the soil sample block, and under the action of the support member, the stability of the sample box can be maintained. When cutting the soil sample block, the structure of the cut soil sample block can be kept roughly the same, and while maintaining the stability of the sample box, the soil structure can be prevented from becoming loose, effectively maintaining the soil quality of the material.

[0008] As a further improvement to the above solution, a hook is further provided on the top of the bracket, a first pull rope is hung on the hook, and one end of the first pull rope is connected to a positioning nail that is nailed into the soil for fixing; The first pull rope is also provided with an adjuster for adjusting the length thereof.

[0009] The technical effect of the above improvement is: by setting the first pull rope, positioning pin, and adjuster, the bracket can be pulled toward the side of the foundation pit wall, thereby maintaining the bracket's support for the sample box, and also with the support of the supporting member, the bracket is kept horizontally placed, so that the sample box and the soil sample block can be effectively fitted, and the structural integrity of the soil can be maintained during sampling.

[0010] As a further improvement of the above solution, first rollers are symmetrically provided on both sides of the bracket, and a cutting wire for cutting the soil sample is wound on the first rollers; Movable components for driving the cutting line to move up and down are movably arranged on both sides of the bracket, and a number of pulleys for changing the moving direction of the cutting line are arranged on the movable components.

[0011] The technical effect of the above improvement is: by setting the cutting line, the soil sample can be removed by cutting during sampling, avoiding the impact of the soil on the bracket when shoveling it off in the traditional way, and avoiding the loosening of the soil. Secondly, the cutting line cutting method can reduce the damage to the soil structure and maintain the basic integrity of the soil structure.

[0012] As a further improvement to the above solution, a slide rail is provided on the side of the bracket and is slidably arranged with respect to the movable component, and a second pull rope is provided on the movable component to pull the movable component up and down; A first roller and a second roller are rotatably provided on both sides of the bracket. The second pull rope for pulling the movable component upwards passes around the first roller, and the second pull rope for pulling the movable component downwards passes around the second roller.

[0013] The technical effect of the above improvement is that by pulling the second pull rope in different directions, the cutting line can be driven to move up and down during the cutting process.

[0014] As a further improvement to the above solution, a second roller for winding the second pull rope is provided on the bracket, and the second roller and the first roller are mutually transmitted via a transmission device; The transmission device includes a transmission disk arranged on the rotating shaft of the second roller, a driving disk is arranged to rotate inside the transmission disk, and the driving disk is provided with a plurality of ratchets that can be clamped with the inner wall of the transmission disk for one-way transmission. An adjusting rod is arranged to rotate inside the rotating shaft of the driving disk, and a plurality of pull wires are connected to the adjusting rod to pull the ratchets out of contact with the transmission disk. A locking assembly is also provided between the adjusting rod and the rotating shaft of the driving disk.

[0015] As a further improvement of the above solution, the transmission device also includes a transmission head and a transmission shaft that are mutually gear-transmitted with the rotating shaft of the first roller, and the transmission shaft and the rotating shaft of the driving disk are driven by a worm gear.

[0016] The technical effect of the above improvement is that, through the transmission device, the cutting of the soil by the cutting line during the movement can be linked with the control of the up and down movement of the cutting line, thereby achieving the effect of changing the cutting position while cutting.

[0017] As a further improvement to the above solution, the second rollers are symmetrically arranged on the bracket in the same number as the first rollers, and the second rollers rotate coaxially via a linkage shaft; The first rollers on both sides drive the second rollers on the corresponding sides to rotate in opposite directions.

[0018] The technical effect of the above improvement is: by setting the first roller on different sides to drive the second roller to rotate in opposite directions, it can be ensured that the rotation direction of the second roller remains unchanged. Therefore, no matter in which direction the first roller rotates, the second pull rope can be continuously wound, so that the cutting line moves up and down to complete the cutting.

[0019] As a further improvement to the above solution, mounting seats are respectively provided at the top and bottom of the bracket, and isolation components are detachably mounted on the mounting seats to prevent the cut soil from falling; The isolation assembly includes a roller mounted on a mounting seat, with isolation cloth wound on the roller, and a pull rod fixedly provided at the end of the isolation cloth. The pull rod is detachably mounted on the end of the movable assembly and extends into the cutting gap following the cutting line.

[0020] The technical effect of the above improvement is: through the isolation component, the isolation cloth can be brought into the cutting gap during the cutting process to block the cut soil sample, and then after the cutting is completed, the soil sample is completely covered to prevent the loose soil from falling, thereby maintaining the soil structure and avoiding damage when taking it out.

[0021] As a further improvement to the above solution, a hook is fixedly provided at the end of the movable assembly for facilitating installation of the pull rod; The pull rod is "C"-shaped, a smooth convex edge is provided on the side of the sample box, and edge ropes are provided on both sides of the isolation cloth.

[0022] The technical effect of the above improvement is that the isolation cloth can completely cover the soil in the sample box through the provided pull rod, thereby reducing the possibility of soil falling.

[0023] As a further improvement of the above solution, the bracket is provided with a guide rail for facilitating the movement of the sample box, and the top of the bracket is also provided with a hanging rope for facilitating hanging. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0027] Embodiment 1:

[0028] like Figure 1-8 As shown, this is Example 1 of the present application. The specific solution of this embodiment is: a device for collecting whole-section cross-section specimens of red soil in the south, including a bracket 10. The bracket 10 is assembled with aluminum alloy profiles and fixed angle irons, and the bracket 10 can be completely disassembled into a state of single parts, which is more convenient when transporting. A sample box 11 is slidably arranged in the bracket 10. Specifically, a guide rail for facilitating the installation of the sample box 11 is provided on the horizontal rod of the bracket 10. Therefore, when in use, it can be smoothly pushed outward and buckled on the soil sample block. The bracket 10 is detachably provided with a limiter for fixing the sample box 11 on the bracket 10 to facilitate buckling the soil sample block. The limiting member 12 is specifically a limiting latch, which is inserted into the guide rail on the sample box 11 to prevent the sample box 11 from moving in the bracket 10 and maintain the stability of the sample box 11. This can avoid deviation when the soil sample is cut and transferred to the sample box 11, thereby maintaining the integrity of the soil sample in the sample box 11. A lifting rope 38 is also provided on the top of the bracket 10 for easy lifting. During use, after the sampling is completed, a small crane or a device with a lifting function is used to lift it. Then, by removing the limiting member 12, the removed soil sample and the sample box 11 can be removed together to reduce manual labor. One side of the bracket 10 is also detachably provided with a support member 13. Specifically, in this embodiment, the support member 13 is a support rod. One end of the support member 13 can be inserted into the bottom of the foundation pit and support the bracket 10 so that the sample box 11 and the soil sample block are fully engaged. The other end of the support member 13 supports the bracket 10, which can support the bracket 10 toward one side of the soil sample block to avoid the situation of moving outward during the removal of the soil sample block, thereby facilitating the complete engagement of the soil sample block during the sampling process and reducing damage to the soil sample block.

[0029] like Figure 1 、 4 As shown, as a preferred embodiment of the above embodiment, a hook 14 is further provided on the top of the bracket 10, and a first pull rope 15 is hung on the hook 14, and one end of the first pull rope 15 is connected to a positioning nail 16 nailed into the soil for fixation; the first pull rope 15 is also provided with an adjuster 17 for adjusting its length. Specifically, during use, the positioning nail 16 is driven into the ground surface, and the length of the first pull rope 15 is continuously adjusted by the adjuster 17, so that the first pull rope 15 can exert a pulling force on the bracket 10, so that in cooperation with the support member 13, the arrangement state of the bracket 10 can be conveniently adjusted, thereby maintaining the horizontal state of the bracket 10 and keeping the sample box 11 able to be smoothly buckled with the soil sample block. At the same time, under the pulling of the two, the bracket 10 can be prevented from moving at will, and when the soil sample block is removed, the sample box 11 is reduced from moving out of the way, which is conducive to maintaining the structural integrity of the removed soil sample block.

[0030] like Figure 1 、 2 , 3, 5, 6, and 7, as a preferred embodiment of the above embodiment, first rollers 18 are symmetrically provided on both sides of the bracket 10. In this embodiment, in order to reduce the overall weight, the bracket 10 is not provided with a driving source interconnected with the first roller 18. The driving source is configured separately when in use, and can be directly rotated manually or driven by a motor. A cutting line 19 for cutting the soil sample is wound on the first roller 18. The structure of the cutting line 19 can be referred to in the attached Figure 7 As shown, many cutting teeth are provided on the surface; The two sides of the bracket 10 are provided with movable components 20 that drive the cutting line 19 to move up and down. Figure 3 As shown, the side of the bracket 10 is provided with a slide rail 21 that slides with the movable component 20, and the movable component 20 is provided with a plurality of pulleys that change the movement direction of the cutting line 19. The movable component 20 includes a sliding seat that slides with the slide rail 21, and a connecting rod is provided between the sliding seats. The pulley is provided on the sliding seat, and a plurality of pulleys with different arrangement directions are also provided at the end of the connecting rod close to one side of the soil sample block, such as Figure 3.

[0031] As a preferred embodiment of the above, the movable component 20 is provided with a second pull rope 22 for pulling the movable component 20 up and down, and the second pull rope 22 is specifically fixed on the connecting rod of the movable component 20; the first roller 23 and the second roller 24 are rotatably provided on both sides of the bracket 10, and the second pull rope 22 for pulling the movable component 20 to move upward bypasses the first roller 23, and the second pull rope 22 for pulling the movable component 20 to move downward bypasses the second roller 24. Therefore, by pulling different second pull ropes 22 to bypass the first roller 23 or the second roller 24, the movable component 20 can be driven to slide upward or downward, so that the method of cutting from top to bottom or from bottom to top can be selected according to the looseness of the soil, so as to facilitate the removal of the soil sample to be used more completely.

[0032] As a preferred embodiment of the above embodiment, mounting seats 34 are respectively provided at the top and bottom of the bracket 10, and an isolation component 35 for preventing the soil from falling after cutting is detachably installed on the mounting seat 34. The isolation component 35 includes a roller 351 installed on the mounting seat 34. The roller 351 adopts a clockwork structure, so it has a pull-back effect. An isolation cloth 352 is wound around the roller 351, and edge ropes 3521 are provided on both sides of the isolation cloth 352. The edge ropes 3521 have a certain elasticity. A pull rod 353 is fixedly provided at the end of the isolation cloth 352. The pull rod 353 is "C"-shaped. The pull rod 353 is detachably installed at the end of the movable component 20 and extends into the cutting gap following the cutting line 19; Figure 3 As shown, a hook 36 is fixedly provided at the end of the movable component 20 for facilitating the installation of the pull rod 353; a smooth convex edge 37 is provided at the side of the sample box 11; in specific use, by hanging the pull rod 353 on the hook 36, the isolation cloth 352 can be pulled out along with the movable component 20 during the soil cutting process. Since the pull rod 353 is a "C"-shaped structure, the sample box 11 and the soil sample in the sample box 11 can be wrapped to reduce the falling of the soil, and the edge rope 3521 can further pull the isolation cloth 352. After the soil sample block is completely cut, the soil sample block in the sample box 11 can be completely sealed under the action of the isolation cloth 352, which not only reduces the loose falling of the soil, but also ensures the integrity of the soil in the sample box 11.

[0033] Example 2:

[0034] like Figure 9-13The figure shows Example 2 of the present invention. This example is a further improvement on Example 1. Specifically, a second roller 25 for winding the second pull rope 22 is provided on the bracket 10. The second roller 25 and the first roller 18 are mutually transmitted through a transmission device. The second rollers 25 are symmetrically arranged on the bracket 10, corresponding to the number of the first rollers 18, and the second rollers 25 rotate coaxially through a linkage shaft 33; the first rollers 18 on both sides drive the second rollers 25 on the same side to rotate in opposite directions.

[0035] The transmission device includes a transmission disc 26 arranged on the rotating shaft of the second winding roller 25, a driving disc 27 is rotatably arranged inside the transmission disc 26, and a plurality of pawls 28 that can be clamped with the inner wall of the transmission disc 26 for one-way transmission are provided on the driving disc 27. A torsion spring is provided between the pawl 28 and the driving disc 27 to ensure long-term contact between the pawl 28 and the transmission disc 26. Since two are provided for the second winding roller 25 and the first winding roller 18, respectively, Figure 10 In the transmission device of the first roller 18 and the second roller 25 on both sides, the unidirectional transmission directions of the pawl 28 and the transmission disc 26 are opposite, that is, the arrangement direction of the pawl 28 is opposite to the arrangement direction of the teeth on the transmission disc 26. An adjusting rod 29 is provided to rotate in the rotating shaft of the drive disc 27. A plurality of pull wires 30 are connected to the adjusting rod 29 to pull the pawl 28 and the transmission disc 26 out of contact. A locking assembly is also provided between the adjusting rod 29 and the rotating shaft of the drive disc 27, such as Figure 13 The locking assembly includes a locking disk arranged at the outer end of the adjusting rod 29, and the rotating shaft of the driving disk 27 extends outward. A pin that is fixed to the shaft end of the driving disk 27 is detachably provided on the locking disk at the end of the adjusting rod 29. By removing the pin, the adjusting rod 29 can be rotated to control the pawl 28 and the transmission disk 26 to disengage from each other. This arrangement makes it more convenient to remove the second pull rope 22 from the second roller 25.

[0036] Figure 11 As shown, the transmission device also includes a transmission head 31 and a transmission shaft 32 that are mutually gear-transmitted with the rotating shaft of the first roller 18. The driving source can be connected through the transmission head 31. Similarly, no driving source is configured here, and the driving source can be manually driven or motor-driven; the transmission shaft 32 and the rotating shaft of the drive disk 27 are driven by a worm gear, and the worm gear is mainly used for deceleration.

[0037] In the specific use process, please refer to the attached Figure 10 , with attached Figure 10The description is made in the up, down, left and right directions. When the first roller 18 on the upper side rotates and pulls the cutting line 19 to move upward for cutting, it is necessary to toggle the locking assembly at the bottom to disconnect the transmission between the second roller 25 and the first roller 18 at the bottom. In this way, the rotation of the first roller 18 at the top will synchronously drive the second roller 25 to rotate to wind up the second pull rope 22, and the first roller 18 at the bottom will rotate back under the pull of the cutting line 19; however, the transmission between the first roller 18 and the second roller 25 at the bottom is disconnected, so it will not affect the rotation of the second roller 25. When the first winding roller 18 at the bottom rotates, it is necessary to control the locking assembly of the second winding roller 25 at the bottom and the first winding roller 18 to connect the two transmissions, and the transmission between the first winding roller 18 and the second winding roller 25 at the top is disconnected. When the first winding roller 18 at the bottom rotates around the cutting line 19, it will rotate in the opposite direction to drive the second winding roller 25 to rotate. At this time, it still drives the second winding roller 25 to rotate in one direction, so it will not affect the winding function of the second winding roller 25. In another special case, when the upper and lower locking assemblies connect the transmission of the first roller 18 and the second roller 25, while strictly paying attention to the rotation direction of the first roller 18, it is possible to automatically keep the second roller 25 rotating in one direction to a certain extent when switching the rotation of different first rollers 18.

[0038] The specific working principle of the present invention is as follows: first, a pit is dug at the selected sampling location, and the side walls of the pit are repaired into a cube-shaped structure. Then, the bracket 10 is hoisted into the pit, and the support members 13 and positioning pins 16 are arranged to completely buckle the sample box 11 into the repaired cube. Then, the limiting member 12 is inserted into the bracket 10 to fix the sample box 11. Choose the cutting direction according to the looseness of the soil. When the soil is loose, cut from bottom to top. When the soil is relatively sticky, cut from top to bottom. This makes it easier to arrange and remove chips. In the specific cutting process, by continuously switching the first roller 18 at different positions to rotate, the cutting line 19 is driven to cut. When the second pull rope 22 is pulled in different directions, the movable component 20 and the cutting line 19 are driven to continuously change positions for cutting. At the same time, under the action of the second roller 25, the cutting line 19 can also be cut. During the cutting process, the movable component 20 drives the isolation component 35 to extend into the cutting gap, which can protect the soil sample in the sample box 11 during the cutting process, prevent the soil from detaching, and protect the integrity of the soil structure. After the soil is completely cut off, the isolation component 35 also seals the soil on the sample box 11, and then the entire bracket 10 and the sample box 11 can be lifted by the lifting rope 38. The isolation component 35 continues to protect the soil, which is more convenient during transfer and transportation. Finally, the limiter 12 is removed, and the sample box 11 is removed from the sample box 11, and the obtained soil sample can be taken out for storage.
