Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and in particular to a screen limiting mechanism for a soil sample sieve. Background Technology

[0002] A soil sample sieve is a tool used to separate soil samples by particle size. It can separate soil particles according to a predetermined sieve aperture size, thereby helping researchers understand the physical properties of the soil, such as texture and particle composition.

[0003] For example, Chinese patent CN219817054U discloses a vibrating screen that is easy to assemble and disassemble, including a base, a U-shaped mounting seat on the top of the base, and mounting mechanisms symmetrically arranged on the front and rear surfaces of the U-shaped mounting seat. Each mounting mechanism includes a spring box, and the inner surfaces of the two spring boxes are fixedly connected to the front and rear surfaces of the U-shaped mounting seat by bolts. A slider is slidably connected to the inner wall of each of the two spring boxes, and a plug rod is fixedly connected to the inner surface of each of the two sliders by bolts. One end of each plug rod passes through the front and rear ends of the U-shaped mounting seat and is inserted into the inner wall of the slot corresponding to its position. A pull rod is fixedly connected to the outer surface of the slider by bolts. One end of the pull rod passes through the end of the spring box corresponding to its position away from the U-shaped mounting seat and is welded and fixed with a pull ring. A spring is provided on the outer circumference of the pull rod, and one end of the spring is fixedly connected to the outer surface of the slider corresponding to its position.

[0004] Although the aforementioned patent solves the problem of the screen being difficult to disassemble and replace through the installation mechanism, the installation structure of the screen lacks a tension adjustment structure. When the soil sample is placed on the screen, it is easy for local depressions to occur under the weight of the sample. These depressions will cause changes in the screen aperture, and smaller soil particles may accumulate in the depressions and cannot pass through the screen smoothly, affecting the accuracy of screening. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing sieve installation structure lacks a tension adjustment structure, and when a soil sample is placed on the sieve, it is easy for local depressions to occur under the weight of the sample. This depression will cause changes in the sieve aperture, and smaller soil particles may accumulate in the depressions and cannot pass through the sieve smoothly, affecting the accuracy of screening. Therefore, a sieve limiting mechanism for a soil sample sieve is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sieve limiting mechanism for a soil sample sieve, comprising a reinforced frame, a tensioning component provided on one side of the reinforced frame, the tensioning component comprising a mounting rod, a connecting frame, and a gear, a fixing member fixedly connected to one side of the mounting rod, a sieve body connected to one side of the fixing member by bolts, a tension spring installed between the mounting rod and the connecting frame, a rack one fixedly connected to one side of the connecting frame, one end of the rack one penetrating through the side wall of the reinforced frame, and the rack one slidably connected to the reinforced frame, a gear meshing at the bottom of the rack one, a crossbar inserted through the gear, a support frame rotatably connected to one end of the crossbar, a rack two slidably connected to one side of the support frame, and an electric push rod fixedly connected to one side of the rack two.

[0007] Preferably, one side of the electric push rod is fixedly connected to the support frame, the top of the rack is meshed with a gear, and one end of the rack penetrates through the side wall of the reinforced frame.

[0008] Preferably, a diagonal bar is fixedly connected to one side of the inner wall of the reinforced frame, a reinforcing strip is fixedly connected to one side of the diagonal bar, and a plug-in rod is fixedly connected to the top of the reinforcing strip.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Refer to Figures 1-4As shown: A sieve limiting mechanism for a soil sample sieve includes a reinforcing frame 2. A tensioning assembly is provided on one side of the reinforcing frame 2. The tensioning assembly includes a mounting rod 12, a connecting frame 18, and a gear 20. A fixing member 15 is fixedly connected to one side of the mounting rod 12. A sieve body 5 is bolted to one side of the fixing member 15. A tension spring 16 is installed between the mounting rod 12 and the connecting frame 18. A rack 17 is fixedly connected to one side of the connecting frame 18. One end of the rack 17 penetrates the side wall of the reinforcing frame 2, and the rack 17 is connected to... The reinforced frame 2 is slidably connected. The bottom of the rack 17 is engaged with a gear 20. A crossbar is inserted through the gear 20. One end of the crossbar is rotatably connected to a support frame 13. One side of the support frame 13 is fixedly connected to the reinforced frame 2. A rack 2 19 is slidably connected to one side of the support frame 13. An electric push rod 14 is fixedly connected to one side of the rack 2 19. One side of the electric push rod 14 is fixedly connected to the support frame 13. The top of the rack 2 19 is engaged with the gear 20. One end of the rack 2 19 penetrates the side wall of the reinforced frame 2.

[0024] The screen body 5 and the mounting rod 12 can be connected by the fixing member 15, and the mounting rod 12 and the connecting frame 18 can be connected by the tension spring 16. The support frame 13 can support one side of the gear 20 and guide the movement of the rack 19. The electric push rod 14 can provide power for the movement of the rack 19, so that the movement of the rack 19 can drive the gear 20 to rotate on one side of the support frame 13. Through the meshing of the gear 20 and the rack 17, the rack can be driven when the gear 20 rotates. The rack 17 moves along the reinforced frame 2, which guides one end of the rack 17. The reinforced frame 2 and the side wall of the rack 17 remain connected during the movement, preventing the rack 17 from separating from the reinforced frame 2. This ensures the stability of the rack 17 during movement. Furthermore, the rack 17 applies tension to the connecting frame 18 and the tension spring 16 during movement, thereby adjusting the tension of the screen body 5. This prevents the soil sample from sinking or loosening when placed in the screen body 5, ensuring the accuracy of soil sample sieving.

[0025] Example 2: Figure 1 and Figure 2 As shown, a diagonal rod 9 is fixedly connected to one side of the inner wall of the reinforced frame 2, a reinforcing strip 11 is fixedly connected to one side of the diagonal rod 9, a plug rod 10 is fixedly connected to the top of the reinforcing strip 11, a baffle 1 is plugged into the top of the plug rod 10, and the bottom of the baffle 1 is engaged with the reinforced frame 2. A rotating block 8 is rotatably connected to one side of the reinforced frame 2, an installation component 6 is fixedly connected to one side of the rotating block 8, an installation ring 4 is fixedly connected to one side of the installation component 6, an extension block 7 is fixedly connected to one side of the installation component 6, a limit strip 3 is engaged on one side of the extension block 7, and the limit strip 3 overlaps with the reinforced frame 2 on one side. An auxiliary component 21 is fixedly connected to one side of the installation component 6, and an installation hole is provided on one side of the auxiliary component 21.

[0026] The baffle 1 can be used to shield the top area of ​​the reinforced frame 2, allowing the soil sample to enter the screen body 5 smoothly. The plug rod 10 can guide the installation of the baffle 1. The diagonal rod 9 and the plug rod 10 can be used to support and reinforce the inner wall of the reinforced frame 2, reducing the deformation of the reinforced frame 2 under stress. The rotation block 8 can be rotated and connected to the reinforced frame 2 to adjust the direction of use of the mounting part 6. The direction of use of the mounting part 6 can be limited by the engagement of the extension block 7 and the limiting strip 3. The mounting ring 4 and the auxiliary part 21 on one side of the mounting part 6 can be used to assist in the connection between the reinforced frame 2 and the screening machine.

[0027] The operating method and working principle of this device are as follows: First, install the tension spring 16 between the mounting rod 12 and the connecting frame 18. Then, use the electric push rod 14 to drive the rack 19 to move along the support frame 13. When the rack 19 moves, the drive gear 20 rotates on one side of the support frame 13. Through the meshing of the gear 20 and the rack 17, the rack 17 is driven to move, thereby pulling the connecting frame 18 to the side away from the fixed part 15. The tension spring 16 is stretched, and then a force is applied to the fixed part 15 and the screen body 5 to adjust the tension of the screen body 5. Select the mounting ring 4 to... Using the direction, when the mounting ring 4 is used horizontally, the limiting strip 3 is engaged with the two extension blocks 7 to limit and fix the mounting part 6. When the mounting ring 4 is used vertically, the mounting part 6 is rotated on one side of the reinforcing frame 2 by rotating the rotating block 8 so that the extension block 7 is located below the mounting ring 4. Then, the mounting part 6 and the reinforcing frame 2 are fixed with bolts. The entire mechanism can be installed on the screening machine through the mounting ring 4. Soil samples are placed on the top of the screen body 5 for screening. When the baffle 1 is not in use, the baffle 1 can be moved up and separated from the plug rod 10, and the baffle 1 can be removed from the top of the reinforcing frame 2.
