Description
Technical Field
[0001] The utility model relates to the technical field of soil sampling and collection, and more specifically, to a foundation soil collection device. Background Art
[0002] In the fields of agricultural production or environmental protection monitoring, in order to ensure the quality of soil, it is necessary to collect and analyze soil. Soil samplers are often used to collect soil samples.
[0003] The existing soil sampler is usually a core sampler, which consists of a core cutter, a soil sampling rod, a semi-cylindrical barrel and a scraper. When taking soil, the core cutter is installed at the top of the soil sampler, and the core cutter of the soil sampler is rotated into the soil until the required depth, and then the sampler is pulled out.
[0004] However, when the existing sampler collects soil at a deeper depth, during the process of pulling out the sampler from the soil, the soil will quickly fall under the action of gravity, which is not convenient for collecting the taken-out soil. At the same time, when collecting soil, it is necessary to take soil at different depths. It is difficult for the soil sampler to accurately control the insertion depth into the soil and the amount of soil taken, and it is difficult to accurately obtain the soil at the required depth.
[0005] In view of this, this application is specifically proposed. Utility Model Content
[0006] The technical problem to be solved by the utility model is that when the sampler collects soil at a deeper depth, during the process of pulling out the sampler from the soil, the soil will quickly fall under the action of gravity, which is not convenient for collecting the taken-out soil. The purpose is to provide a foundation soil collection device. Through the special structure setting of the collection inner cylinder, the sampler can clamp the soil to avoid the falling of the sampled soil and affect the soil collection.
[0007] The utility model is realized through the following technical solutions:
[0008] A foundation soil collection device includes a soil collection outer cylinder, the bottom of the soil collection outer cylinder has an opening, and a cutting cylinder is coaxially arranged at the opening;
[0009] A collection inner cylinder is arranged inside the soil collection outer cylinder. The collection inner cylinder is made of rubber material. There is a gap between the inner wall of the soil collection outer cylinder and the outer wall of the collection inner cylinder. When the wall surface of the collection inner cylinder is subjected to an outward force from the inside, it can produce elastic deformation in the direction of the soil collection outer cylinder;
[0010] The inner wall diameter of the collection inner cylinder is the same as the inner wall diameter of the cutting cylinder;
[0011] A depth adjustment top block is arranged inside the collection inner cylinder, and the depth adjustment top block can freely move up and down or rotate along the inner wall of the collection inner cylinder.
[0012] Through the special structural arrangement of the inner cylinder in the present utility model, the sampler can clamp the soil, avoiding the falling of the sampled soil and affecting the soil collection.
[0013] When the soil collection device of the present utility model is in use, first make the bottom end of the cutting cylinder fit with the soil surface, press the outer cylinder of the soil collection, the cutting cylinder cuts the soil and gradually moves towards the inner layer of the soil, and the soil is squeezed into the collection inner cylinder from the cutting cylinder. Since the collection inner cylinder has a certain elasticity, the collection inner cylinder will deform after a large amount of soil is squeezed in, so that the collection inner cylinder can provide an inward clamping force to the soil, making the soil structure more compact. When reaching the final sampling depth, the soil in the collection inner cylinder is already in close contact with the depth adjustment top block. At this time, the depth adjustment top block can be slightly pressed down to make the soil in the collection inner cylinder more compact and the interaction force with the collection inner cylinder greater. Then lift the outer cylinder of the soil collection, and the soil is taken out accordingly.
[0014] Usually during soil collection, the filling density of the soil in the cylinder does not change. Therefore, during the process of taking out the soil, the soil will fall due to being too loose and is difficult to take out. In this application, by setting a collection inner cylinder made of rubber material with slight elasticity, during the process of the device penetrating into the soil, due to the elasticity of the collection cylinder body, more soil can be squeezed into it, and the soil can be further pressed tightly under the reaction force of the collection cylinder body, making the soil bond stronger, and at the same time, it can tightly wrap the collected soil, thus being more conducive to taking out the soil and avoiding falling during the taking-out process.
[0015] Among them, by adjusting the position of the depth adjustment top block in the collection inner cylinder, the depth of soil sampling can be controlled.
[0016] In a specific embodiment, the side wall of the collection inner cylinder sequentially has annular convex cavities distributed along the circumferential direction of the collection inner cylinder from top to bottom, and the annular convex cavities make the side wall of the collection inner cylinder form a serrated structure.
[0017] In a specific embodiment, the cross-section of the annular convex cavity is a triangular structure.
[0018] In the present utility model, by setting the side wall of the collection inner cylinder into a serrated structure, the collection inner cylinder can have greater deformation ability inside the outer cylinder of the soil collection, can better wrap the collected soil in the reverse direction, and at the same time, the collected soil can be embedded into the annular convex cavities, increasing the contact area between the collection inner cylinder and the soil. It is equivalent to the inner wall of the collection inner cylinder being embedded into the whole soil to play a role in grasping and clamping the soil, further improving the ability of loading and taking out the soil and avoiding the falling of the soil.
[0019] In a specific embodiment, an adjusting rod is connected to the depth-adjusting top block. The upper end of the adjusting rod extends outside the top end of the soil collection outer cylinder, and the movement of the depth-adjusting top block in the collection inner cylinder is controlled by the adjusting rod.
[0020] In a specific embodiment, a fixed clamping plate is fitted on the outer wall of the upper end of the adjusting rod. The lower end of the fixed clamping plate is fixedly installed at the top end of the soil collection outer cylinder. Horizontal clamping grooves are sequentially formed in the fixed clamping plate from top to bottom. One end of the horizontal clamping groove penetrates through the fixed clamping plate. A clamping strip with a size matching that of the horizontal clamping groove is arranged on the outer wall of the adjusting rod. By horizontally rotating the adjusting rod, the clamping strip can be horizontally inserted into the horizontal clamping groove to realize the height limit of the adjusting rod.
[0021] The utility model realizes the position positioning of the depth-adjusting top block in the collection inner cylinder through the clamping strip arranged on the outer wall of the adjusting rod and the horizontal clamping groove on the fixed clamping plate, and can conveniently and quickly realize the adjustment of the soil collection space and depth in the collection inner cylinder.
[0022] In a specific embodiment, a support cylinder is coaxially sleeved on the outer wall of the soil collection outer cylinder. A stable support disk is arranged on the outer wall of the lower end of the support cylinder. The soil collection outer cylinder can slide up and down along the inner wall of the support cylinder. By arranging the support cylinder in the utility model, the stable support disk provides a large enough contact area with the soil to avoid the inclination of the support cylinder body, thereby ensuring the perpendicularity and stability when the soil collection outer cylinder penetrates into the soil.
[0023] In a specific embodiment, drill bits are arranged on the outer wall of the cutting cylinder. The diameter of the circle where the outermost edge of the drill bit is located is smaller than the inner diameter of the support cylinder. By arranging the drill bits, the process of the cutting cylinder penetrating downward can be made easier. The drill bits can adopt existing soil drilling tools, etc. The specific electromechanical drive circuit structure can be adaptively selected according to the prior art, and the present application does not improve the drill bit structure of the present application.
[0024] In a specific embodiment, a pressing operation plate is installed on the soil collection outer cylinder.
[0025] In a specific embodiment, the pressing operation plate is arranged above the soil collection outer cylinder, and the pressing operation plate and the soil collection outer cylinder are connected by a force-bearing rod.
[0026] The utility model realizes the downward operation of the soil collection outer cylinder by arranging the pressing operation plate, and is more convenient and labor-saving to use.
[0027] In a specific embodiment, a first ring plate is sleeved on the outer wall of the upper end of the soil collection outer cylinder, and the first ring plate is slidably connected to the inner wall of the support cylinder; a second ring plate is provided on the inner wall of the lower end of the support cylinder, and the second ring plate is slidably connected to the outer wall of the soil collection outer cylinder; a spring is installed and connected between the first ring plate and the second ring plate.
[0028] In the utility model, by arranging a spring between the soil collection outer cylinder and the support cylinder, when the soil collection outer cylinder moves downward for soil collection, the spring is compressed. After the collection is completed, under the action of the spring, an upward reverse force can be provided to the soil collection outer cylinder, thus facilitating the removal of the soil collection outer cylinder.
[0029] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0030] 1. A foundation soil collection device provided by an embodiment of the utility model can clamp the soil through the special structure setting of the collection inner cylinder, avoiding the sampled soil from falling off and affecting the soil collection.
[0031] 2. A foundation soil collection device provided by an embodiment of the utility model. Since the collection inner cylinder has a certain elasticity, the collection inner cylinder will deform after a large amount of soil is squeezed in.

When reaching the final sampling depth, the soil filled in the collection inner cylinder is already in close contact with the depth adjustment top block. At this time, the depth adjustment top block can be slightly pressed down to make the soil in the collection inner cylinder more compact and the interaction force with the collection inner cylinder greater. Then, the soil collection outer cylinder is lifted, and the soil is taken out accordingly.
