Abstract
Description
Technical Field
[0001] This utility model relates to the field of shrub litter technology, specifically a stratified sampler for sand-fixing shrub litter. Background Technology
[0002] In the process of sand fixation, samplers are widely used to sample shrub litter. Dead and decomposing plant debris scattered on the ground surface—either naturally falling off from the plant or detached from the parent plant due to trampling by livestock or wind—is in close contact with the soil surface and decomposes very easily. While livestock cannot utilize it, it can increase soil fertility. To estimate the true net aboveground productivity, litter should be collected and its weight measured simultaneously with the determination of the existing aboveground quantity. Samplers are also used in the sand fixation process.
[0003] Existing samplers require the drill bit to be continuously inserted into shrub litter when performing stratified sampling. After sampling at one depth, the sample is removed, and then sampling is performed again at a different depth, repeating this process to achieve multi-layer sampling.
[0004] However, existing samplers cannot simultaneously sample multiple layers of soil at different depths. To sample soil at different depths, it is necessary to continuously drill the soil-drilling device into the soil and then sample sequentially at different depths, which is cumbersome and time-consuming. To address these issues, a layered sampler for sand-fixing shrub litter is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a layered sampler for litter from sand-fixing shrubs, which solves the problem in the prior art that requires continuously drilling the soil into the soil and then sampling at different depths, which is cumbersome and time-consuming.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a layered sampler for litter from sand-fixing shrubs, comprising a base plate, two side plates fixedly connected to the top of the base plate, a slide rail fixedly connected to the front top of the base plate, a motor fixedly connected to the bottom of the inner wall of the slide rail, a lead screw fixedly connected to the output end of the motor, a nut pair threadedly connected to the outer ring of the lead screw, a first fixing plate fixedly connected to one side of the nut pair, a sampler fixedly connected to the bottom of the first fixing plate, a support plate fixedly connected to one side of the inner ring of the sampler, a cylinder fixedly connected to the top of the inner wall of the support plate, a U-shaped plate fixedly connected to the output end of the cylinder, two support plates rotatably connected to the inner wall of the U-shaped plate, a moving rod rotatably connected to one side of each of the two support plates, a second connecting plate fixedly connected to one side of each of the two moving rods, and evenly distributed covers fixedly connected to one side of each of the two second connecting plates. A collection cylinder is threadedly connected to the inner ring of each cover, evenly distributed scraping rings are fixedly connected to the inner wall of the sampler, a plug is threadedly connected to the bottom of the sampler, and a stabilizing component is provided at the bottom of the first fixing plate.
[0007] By adopting the above technical solution, starting the motor and driving the first fixed plate to move upward, the sampler can be inserted into the shrub litter. Then, starting the cylinder pushes the U-shaped plate, which drives the support plate to rotate, causing the moving rod to move under the limit of the limit track. This allows multiple collection cylinders of different heights to be pushed out of the sampler, achieving stratified sampling.
[0008] As a further description of the above technical solution: the stabilizing component includes a pressure plate, which is fixedly connected to a first fixed plate. Limiting grooves are formed on one side of each of the two side plates. A first connecting plate is slidably connected between the inner walls of the two limiting grooves. Two second fixed plates are fixedly connected to the bottom of the first connecting plate. Sliding rods are fixedly connected to the bottom of each of the two second fixed plates. Insert plates are fixedly connected to the bottom of each of the two adjacent sliding rods. A third fixed plate is fixedly connected to one side of each of the two side plates. Two limiting plates are fixedly connected to the rear top of the bottom plate. Support rods are threadedly connected between the inner walls of the two limiting plates. Moving plates are slidably connected to the outer rings of the two support rods. A T-shaped plate is provided between the two moving plates. Springs are sleeved on the bottom of the outer rings of the two support rods.
[0009] By adopting the above technical solution, the stability of the sampler can be increased when the stabilizing component is sampling.
[0010] As a further description of the above technical solution: a limiting track is fixedly connected between the inner walls of the sampler, and a moving rod is slidably connected to the inner wall of the limiting track.
[0011] By adopting the above technical solution, the moving rod is limited by the track.
[0012] As a further description of the above technical solution: the inner ring of the scraper ring is slidably connected to a collecting cylinder.
[0013] By adopting the above technical solution, the scraper ring can scrape off impurities from the outer surface of the collection cylinder.
[0014] As a further description of the above technical solution: a first connecting plate is fixedly connected to the bottom of the T-shaped plate.
[0015] By adopting the above technical solution, when the T-shaped plate is subjected to a downward force, it will drive the first connecting plate to move downward.
[0016] As a further description of the above technical solution: a movable plate is slidably connected to the inner wall of the limiting plate, a third connecting plate is fixedly connected to one side of the limiting plate, and a damper is provided at the bottom of the third connecting plate.
[0017] By adopting the above technical solution, when the T-shaped plate resets upwards quickly, the damper can provide buffering and improve its service life.
[0018] As a further description of the above technical solution: the outer ring of the slide rod is slidably connected to a third fixing plate, and two wheels are provided at the bottom of the two third fixing plates.
[0019] By adopting the above technical solution, the wheel can be lifted off the ground when the slide bar slides downwards.
[0020] As a further description of the above technical solution: a nut pair is slidably connected to the inner wall of the slide rail, and the top of the lead screw is rotatably connected to the slide rail.
[0021] By adopting the above technical solution, when the lead screw rotates, the upper part and the slide rail also rotate.
[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0023] 1. This utility model provides a layered sampler for sand-fixing shrub litter. It consists of a cylinder, a support plate, a moving rod, a collection cylinder, and a scraper ring. When the motor is started, it moves the first fixed plate upwards, allowing the sampler to be inserted into the shrub litter. Then, the cylinder is activated, pushing the U-shaped plate and rotating the support plate. This causes the moving rod to move within the limit rail, pushing multiple collection cylinders of different heights out of the sampler, achieving layered sampling. After sampling, the moving rod is reset. When the collection cylinder re-enters the sampler, the scraper ring removes impurities from the outside of the collection cylinder, reducing the amount of impurities entering. Sampling is simple, convenient, and time-saving.
[0024] 2. The present invention provides a layered sampler for litter from sand-fixing shrubs. The sampler consists of a first connecting plate, a limiting plate, a support rod, a spring, and an insert plate. When the first fixed plate moves downward to a certain position, the pressure plate contacts the T-shaped plate, thereby driving the first connecting plate downward. This causes the moving plate to slide within the limiting plate and compress the spring, causing the insert plate to move downward and insert into the ground. Simultaneously, the wheels are moved away from the ground, increasing stability during layered sampling. When the first fixed plate moves upward, the spring causes the moving plate to reset, ensuring it is not affected for future use. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0033] Combination Figure 1and Figure 2 This utility model discloses a layered sampler for litter from sand-fixing shrubs, comprising a base plate 1, two side plates 2 fixedly connected to the top of the base plate 1, a slide rail 5 fixedly connected to the front top of the base plate 1, and a motor 11 fixedly connected to the bottom inner wall of the slide rail 5. When the controller controls the motor 11 to work, it can drive the lead screw 6 to rotate, causing the nut pair 7 to move within the slide rail 5, thereby driving the first fixed plate 8 to move up and down. The output end of the motor 11 is fixedly connected to the lead screw 6, and the outer ring of the lead screw 6 is threadedly connected to the nut pair 7. The first fixed plate 8 is fixedly connected to one side of the nut pair 7. When the first fixed plate 8 moves downward, it can first drive the sampler 10 to move. After the pressure plate contacts the T-shaped plate 33, it can drive the insert plate 26 to move downward. The sampler 10 is fixedly connected to the bottom of the first fixed plate 8, the nut pair 7 is slidably connected to the inner wall of the slide rail 5, and the top of the lead screw 6 is rotatably connected to the slide rail 5.
[0034] Combination Figures 2-4 A support plate 16 is fixedly connected to one side of the inner ring of the sampler 10. A cylinder 17 is fixedly connected to the top of the inner wall of the support plate 16. When the cylinder 17 works, it can push the U-shaped plate 1 downward, causing the support plate 19 to rotate, and then drive the moving rod 20 to move within the limiting track 21. A U-shaped plate 18 is fixedly connected to the output end of the cylinder 17. Two support plates 19 are rotatably connected to the inner wall of the U-shaped plate 18. A moving rod 20 is rotatably connected to one side of each of the two support plates 19. A second connecting plate 15 is fixedly connected to one side of each of the two moving rods 20. Evenly distributed covers 14 are fixedly connected to one side of each of the two second connecting plates 15. After sampling is completed, a portion of the collection cylinder 12 can be removed from the sampler 10. Then, by rotating the collection cylinder 12, it can be removed. The inner ring of the cover 14 is threaded with the collection cylinder 12. The inner wall of the sampler 10 is fixedly connected with evenly distributed scraping rings 13. The bottom of the sampler 10 is threaded with a plug 34. By rotating the plug plate 34, the impurities collected inside can be taken out from below. The bottom of the first fixed plate 8 is provided with a stabilizing component. The inner walls of the sampler 10 are fixedly connected with a limiting track 21. The inner wall of the limiting track 21 is slidably connected with a moving rod 20. When the collection cylinder 12 needs to enter the sampler 10, the scraping ring 13 will scrape the collection cylinder 12 first. The inner ring of the scraping ring 13 is slidably connected with the collection cylinder 12. The bottom of the T-shaped plate 33 is fixedly connected with the first connecting plate 4.
[0035] Combination Figure 1 and Figure 5The stabilizing component includes a pressure plate 9, which is fixedly connected to a first fixed plate 8. Limiting grooves 3 are formed on one side of each of the two side plates 2. A first connecting plate 4 is slidably connected between the inner walls of the two limiting grooves 3, limiting the movement of the first connecting plate 4 within the limiting grooves 3. Two second fixed plates 22 are fixedly connected to the bottom of the first connecting plate 4. Sliding rods 23 are fixedly connected to the bottom of each of the two second fixed plates 22. When the second fixed plates 22 are subjected to force, they push the sliding rods 23 to move, causing the insert plate 26 to insert into the ground, thus moving the wheel 25 away from the ground and increasing stability. Insert plates 26 are fixedly connected to the bottom of each adjacent sliding rod 23. A third fixed plate 24 is fixedly connected to one side of each of the two side plates 2. Two limiting plates 27 are fixedly connected to the rear top of the bottom plate 1, and the inner walls of the two limiting plates 27 are threaded together. With support rod 30 attached, spring 31 will deform after long-term use. T-shaped plate 33 can be moved downwards and removed first, and then support rod 30 can be rotated to remove it and replace spring 31. Movable plate 32 is slidably connected to the outer ring of both support rods 30, and T-shaped plate 33 is set between the two movable plates 32. Spring 31 is sleeved at the bottom of the outer ring of both support rods 30. Movable plate 32 is slidably connected to the inner wall of limiting plate 27. Third connecting plate 28 is fixedly connected to one side of limiting plate 27. Damper 29 is set at the bottom of third connecting plate 28. When the T-shaped plate 33 resets at a high frequency, the damper 29 above can also buffer it. Third fixed plate 24 is slidably connected to the outer ring of slide rod 23. Two wheels 25 are set at the bottom of the two third fixed plates 24.
[0036] Working principle: In use, push the device to the area where sampling is required, then use the controller to operate the motor 11, which drives the lead screw 6 to rotate, causing the nut assembly 7 to move. This moves the first fixing plate 8 downward, thus inserting the sampler 10 into the shrub litter. Next, control the cylinder 17 to operate, pushing the U-shaped plate 18 downward, which in turn pushes the moving rod 20 to move under the limit of the limiting track 21, causing the collection cylinder 12 to extend out of the sampler 10 for multi-layer sampling. After sampling is completed, the cylinder 17 drives the U-shaped plate 18 to reset, allowing the collection cylinder 12 to enter the sampler 10. During entry, the collection cylinder 12 slides inside the scraping ring 13, which scrapes away impurities from the outside of the collection cylinder 12, reducing the amount of impurities entering the sampler 10. The plug 34 can be rotated to remove the internal impurities, and then the collection cylinder 12 can be rotated. 2. The collecting cylinder 12 can be removed from the cover 14. When the first fixing plate 8 moves down to a certain position, the pressure plate 9 contacts the T-shaped plate 33, which allows the second fixing plate 22 to move down. At the same time, the moving plate 32 slides within the limiting plate 27, squeezing the spring 31, causing the insert plate 26 to insert into the ground, and the wheel 25 to move away from the ground, increasing its stability. When the first fixing plate 8 returns to its original position, there is no force to press the spring 31. The spring 31 returns to its original position with the moving frequency of the first fixing plate 8, causing the insert plate 26 to move out of the ground, and the wheel 25 to contact the ground. When the T-shaped plate 33 returns to its original position at a high frequency, the damper 29 above can also provide buffering. When the spring 31 has been used for a long time and its elasticity has deteriorated, it can slide upward to remove the T-shaped plate 33. Then, the support rod 30 can be rotated and removed to replace the spring 31. This method is convenient to use.
