Description

Technical Field

[0001] This utility model relates to the field of soil testing, specifically to a soil sieve for soil testing. Background Technology

[0002] Soil testing is the process of analyzing and determining soil characteristics using physical, chemical, and biological methods to assess soil quality, fertility, and pollution levels. Its main testing contents include physical properties (such as soil texture measured by touch or mechanical sieving, and bulk density measured using the ring sampler method to calculate porosity) and chemical properties (such as pH measured using potentiometry, and the content of macroelements such as nitrogen, phosphorus, and potassium, and microelements such as iron, manganese, and zinc, using the Kjeldahl method).

[0003] Soil sieving is required during soil testing, necessitating the use of a soil sieve. Publication number CN216349903U discloses a rapid soil sieve for soil testing, "including a sieve housing, with support legs fixedly connected to the four corners of the lower surface of the sieve housing, and a hopper fixedly connected to one side of the upper surface of the sieve housing… thereby achieving multi-stage soil sieving more conveniently and efficiently, solving the problem of the single sieving method in existing devices, affecting sieving quality and efficiency." While this improves sieving efficiency and quality, its sieving method involves the up-and-down shaking of the sieve, which causes soil to splash into the environment during sieving, thus impacting the environment. Furthermore, the sieve lacks an installation and disassembly structure, making it impossible to replace when damaged. Therefore, this application proposes a soil sieve for soil testing to meet this need. Utility Model Content

[0004] Technical problems to be solved: The up-and-down shaking screening method causes soil to splash into the outside and the screen cannot be replaced when it is damaged.

[0005] To address the shortcomings of existing technologies, this utility model provides a soil sieve for soil testing, solving the problems mentioned in the background section. Technical solution:

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A soil sieve for soil testing includes a sieve box, an impurity outlet on one side of the sieve box, a U-shaped mounting frame inside the sieve box, a mounting plate on one side of the mounting frame, a screen inside the mounting frame, a drive assembly at the connection between the mounting frame and the sieve box, an mounting assembly at the connection between the mounting plate and the mounting frame, and a support frame fixedly connected to the bottom outer periphery of the sieve box, with support legs fixedly connected to the bottom of each of the four corners of the support frame.

[0008] In one possible implementation, the drive assembly includes a guide groove, a through groove, locking teeth, a mounting base, a rotating shaft, and a sector block. The through groove extends through the inner wall of the screening box on the side away from the impurity outlet. The guide groove extends through both inner walls of the screening box except for the impurity outlet and the through groove and is adapted to the size of the mounting frame. The mounting base is fixedly connected to the side of the support frame below the through groove. The rotating shaft is fixedly connected to the top of the mounting base. The sector block is rotatably connected to the top of the rotating shaft. Locking teeth are fixedly connected to one side of both the mounting frame and the sector block and they mesh with each other.

[0009] In one possible implementation, the drive assembly further includes a rectangular block, a drive slot, a motor, a rotating wheel, and a rotating rod. The rectangular block is fixedly connected to the outer end of the sector block, the drive slot passes through the middle of the rectangular block, the motor is mounted on the top of the mounting base and is located on one side of the rotating shaft, the rotating wheel is fixedly connected to the top of the motor drive shaft, the rotating rod is fixedly connected to the top of the rotating wheel and is eccentrically positioned, and the rotating rod is slidably connected to the drive slot.

[0010] In one possible implementation, the mounting assembly includes a slot and a block. The slot is formed on the inner wall of one side of the mounting frame and the mounting plate. The block is fixedly connected to both sides of the screen and is adapted to the size of the slot. One end of the mounting plate is rotatably connected to one end of the mounting frame.

[0011] In one possible implementation, the mounting assembly further includes a fixing groove, a fixing block, a fixing hole, a vertical groove, and a fixing rod. The fixing groove is located at the other end of the mounting frame. The fixing block is fixedly connected to the other end of the mounting plate and is adapted to the size of the fixing groove. The fixing hole passes through the fixing block. The vertical groove passes through the inner wall of the top of the fixing groove. The fixing rod is movably connected to the vertical groove and is adapted to the size of the fixing hole.

[0012] In one possible implementation, the mounting assembly further includes a slide, a slider, a spring, and a groove. The slide is formed on the inner wall of the vertical groove. The slider is fixedly connected to the outer periphery of the fixed rod and slidably connected to the slide. The spring is sleeved on the outer periphery of the fixed rod and its two ends are respectively fixedly connected to the top of the slider and the inner wall of the top of the slide. The groove is formed on both sides of the top of the vertical groove.

[0013] Beneficial effects:

[0014] Firstly, by setting up a drive component, starting the motor causes it to drive the rotating rod to rotate via the rotating wheel. Since the rotating rod is slidably connected to the drive groove and the sector block is rotatably connected to the rotating shaft and fixedly connected to the rectangular block, the rectangular block will drive the sector block to reciprocate in a sector-shaped motion as the rotating rod rotates. Furthermore, since the locking teeth of the sector block mesh with the locking teeth of the mounting frame and the guide groove is adapted to the size of the mounting frame, the mounting frame will drive the screen to reciprocate horizontally along the guide groove as the sector block reciprocates, thereby screening the soil. This design allows the screen to screen the soil through horizontal reciprocating motion, which, compared to up-and-down shaking, will not cause soil to splash out and have an impact on the environment.

[0015] Secondly, by incorporating an installation component, a finger is placed in the groove and pulled upwards on the fixing rod, causing the slider to slide upwards along the groove and compress the spring. After the fixing rod moves out of the fixing hole, the mounting plate is rotated to move the fixing block out of the fixing groove. Then, the screen is placed in the mounting frame and the locking block is inserted into the locking slot. Subsequently, the mounting plate is rotated in the opposite direction to move the fixing block into the fixing groove, aligning the fixing hole and the fixing rod on the same axis. At this point, the fixing rod is released, the spring rebounds, and the slider moves the fixing rod downwards. When the fixing rod is inserted into the fixing hole, the fixing block is fixed in the fixing groove, thus forming a U-shaped whole between the mounting plate and the mounting frame, thereby fixing the screen in the mounting frame. This design makes the installation and removal of the screen simple and quick, effectively improving work efficiency. Attached Figure Description

[0028] This application provides a soil sieve for soil testing, thereby solving the problems in the prior art.

[0029] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0030] The specific structure of this embodiment is as follows: Figures 1 to 6 As shown, a soil sieve for soil testing includes a sieve box 1, an impurity outlet 2 on one side of the sieve box 1, a U-shaped mounting frame 3 inside the sieve box 1, a mounting plate 4 on one side of the mounting frame 3, a screen 5 inside the mounting frame 3, a drive assembly 6 at the connection between the mounting frame 3 and the sieve box 1, an installation assembly 7 at the connection between the mounting plate 4 and the mounting frame 3, and a support frame 8 fixedly connected to the bottom outer periphery of the sieve box 1, with support legs 9 fixedly connected to the bottom of each of the four corners of the support frame 8.

[0031] In some examples, the drive assembly 6 includes a guide groove 61, a through groove 62, a retaining tooth 63, a mounting base 64, a rotating shaft 65, and a sector block 66. The through groove 62 penetrates the inner wall of the screening box 1 on the side away from the impurity outlet 2. The guide groove 61 penetrates the inner walls of both sides of the screening box 1, excluding the impurity outlet 2 and the through groove 62, and is adapted to the size of the mounting frame 3. The mounting base 64 is fixedly connected to the side of the support frame 8 below the through groove 62. The rotating shaft 65 is fixedly connected to the top of the mounting base 64. The sector block 66 is rotatably connected to... At the top of the rotating shaft 65, the mounting frame 3 and the side of the sector block 66 are both fixedly connected with locking teeth 63 and they mesh with each other. Rotating the sector block 66 along the rotating shaft 65 causes the locking teeth 63 on one side of it to rotate in the through groove 62. Since the locking teeth 63 on one side of the mounting frame 3 mesh with the locking teeth 63 of the sector block 66, the mounting frame 3 will move horizontally along the through groove 62 with the locking teeth 63 on one side of it, thereby screening the soil on the surface of the screen 5. During this process, the guide groove 61 will limit and guide the mounting frame 3. In some examples, the drive assembly 6 also includes a rectangular block 67, a drive groove 68, a motor 69, a rotating wheel 610, and a rotating rod 611. The rectangular block 67 is fixedly connected to the outer end of the sector block 66, the drive groove 68 passes through the middle of the rectangular block 67, the motor 69 is mounted on the top of the mounting base 64 and is located on one side of the rotating shaft 65, the rotating wheel 610 is fixedly connected to the top of the drive shaft of the motor 69, the rotating rod 611 is fixedly connected to the top of the rotating wheel 610 and is eccentrically set, and the rotating rod 611 is slidably connected to the drive groove 68. When the motor 69 is started, the rotating rod 611 will be driven to rotate through the rotating wheel 610. Since the rotating rod 611 is slidably connected to the drive groove 68 and the sector block 66 is rotatably connected to the rotating shaft 65 and fixedly connected to the rectangular block 67, the rectangular block 67 will drive the sector block 66 to perform reciprocating sector motion as the rotating rod 611 rotates.

[0032] In some examples, the mounting component 7 includes a slot 71 and a block 72. The slot 71 is formed on the inner wall of one side of the mounting frame 3 and the mounting plate 4. The block 72 is fixedly connected to both sides of the screen 5 and is adapted to the size of the slot 71. One end of the mounting plate 4 is rotatably connected to one end of the mounting frame 3. The screen 5 can be fixed in the mounting frame 3 by placing the blocks 72 on both sides of the screen 5 into the slot 71 of the mounting frame 3 and the mounting plate 4.

[0033] In some examples, the mounting assembly 7 also includes a fixing groove 73, a fixing block 74, a fixing hole 75, a vertical groove 76, and a fixing rod 77. The fixing groove 73 is located at the other end of the mounting frame 3. The fixing block 74 is fixedly connected to the other end of the mounting plate 4 and is adapted to the size of the fixing groove 73. The fixing hole 75 passes through the fixing block 74. The vertical groove 76 passes through the inner wall of the top of the fixing groove 73. The fixing rod 77 is movably connected to the vertical groove 76 and is adapted to the size of the fixing hole 75. The fixing block 74 is placed in the fixing groove 73, and then the fixing rod 77 is inserted into the fixing hole 75. At this time, the fixing block 74 can be fixed in the fixing groove 73, thereby connecting the mounting plate 4 and the mounting frame 3.

[0034] In some examples, the mounting component 7 also includes a slide 78, a slider 79, a spring 710, and a groove 711. The slide 78 is formed on the inner wall of the vertical groove 76. The slider 79 is fixedly connected to the outer periphery of the fixed rod 77 and slidably connected to the slide 78. The spring 710 is sleeved on the outer periphery of the fixed rod 77 and its two ends are fixedly connected to the top of the slider 79 and the top inner wall of the slide 78, respectively. The groove 711 is formed on both sides of the top of the vertical groove 76. When a finger is placed in the groove 711 and the fixed rod 77 is pulled upward, the slider 79 will slide upward along the slide 78 and squeeze the spring 710. When the fixed rod 77 is released, the spring 710 will rebound and the fixed rod 77 will move downward through the slider 79.

[0035] In a specific application scenario, first, place your finger in the groove 711 and pull the fixing rod 77 upwards, causing the slider 79 to slide upwards along the groove 78 and compress the spring 710. After the fixing rod 77 moves out of the fixing hole 75, rotate the mounting plate 4 to move the fixing block 74 out of the fixing groove 73. Then, place the screen 5 in the mounting frame 3 and insert the locking block 72 into the locking slot 71. Then, rotate the mounting plate 4 in the opposite direction to move the fixing block 74 into the fixing groove 73, so that the fixing hole 75 and the fixing rod 77 are on the same axis. At this time, release the fixing rod 77. The spring 710 rebounds and moves the fixing rod 77 downwards through the slider 79. When the fixing rod 77 is inserted into the fixing hole 75, the fixing block 74 is fixed in the fixing groove 73, so that the mounting plate 4 and the mounting frame 3 form a U-shaped whole, thereby fixing the screen 5 in the mounting frame 3. Then, add the soil to be screened into the screening box 1. The motor 69 is started, causing it to drive the rotating rod 611 to rotate via the rotating wheel 610. Since the rotating rod 611 is slidably connected to the drive groove 68 and the sector block 66 is rotatably connected to the rotating shaft 65 and fixedly connected to the rectangular block 67, the rectangular block 67 will drive the sector block 66 to reciprocate in a sector-shaped motion as the rotating rod 611 rotates. Since the locking teeth 63 of the sector block 66 mesh with the locking teeth 63 of the mounting frame 3 and the guide groove 61 is adapted to the size of the mounting frame 3, the mounting frame 3 will drive the screen 5 to reciprocate horizontally along the guide groove 61 as the sector block 66 reciprocates, thereby screening the soil. When it is necessary to screen soil of different specifications or the screen 5 is damaged, the fixing rod 77 is pulled upward again to move it out of the fixing hole 75. Then, the mounting plate 4 is rotated to move the fixing block 74 out of the fixing groove 73, thereby disconnecting the mounting plate 4 from the mounting frame 3. At this time, the screen 5 can be taken out for replacement.

[0036] By adopting the above technical solution, not only can the screen be used to screen the soil through horizontal reciprocating motion, which will not cause soil to splash out and affect the environment compared to up-and-down shaking, but the installation and disassembly of the screen are also simpler and faster, effectively improving work efficiency.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
