Description

Technical Field

[0001] The utility model belongs to the field of mixing equipment, in particular to a sample mixing device. Background Art

[0002] Soil is an essential factor in agricultural production. Investigating the comprehensive condition of soil and understanding its fertility and other aspects is crucial for crop cultivation. Fertilizer is a crucial input in agricultural production, playing an irreplaceable role in supporting crop growth and development, improving soil properties, and increasing crop yield and quality. Testing the comprehensive condition of soil and fertilizer is a crucial means of understanding soil fertility and crop production needs. Before testing soil and fertilizer, soil samples collected from multiple sampling points often need to be thoroughly mixed to ensure accurate and representative soil and fertilizer test results. Currently, the most common methods for mixing samples are either using a stirring device or using kraft paper to tilt the corners. However, stirring devices are often cumbersome to use, difficult to clean, and costly. Using kraft paper directly for mixing can easily lead to wear and spillage, resulting in inconvenience and large errors. Utility Model Content

[0037] like Figure 1-3 As shown, the present invention provides a sample mixing device, which is particularly suitable for mixing solid samples such as soil. The sample mixing device includes a shell 1.

[0038] like Figure 1 As shown, the side of the housing 1 is a baffle 101. The baffle 101 can prevent the sample used for mixing from being spilled. The housing 1 can be in various shapes such as circular or polygonal (the top view or cross section is circular or polygonal), and the user can choose according to actual needs. Figure 1 As shown, the housing 1 is a quadrilateral, and baffles 101 are provided on all four edges of the housing 1. A grip ring 2 is provided at the corners of the housing 1 to facilitate the operator to hold the entire sample mixing device. Figure 1 As shown, a grip ring 2 is provided at each of the four corners of the housing 1, which makes it easier for the user to hold the entire sample mixing device. Furthermore, multiple handles 3 ( Figure 1 Two handles 3 are provided on the baffles 101 on each of the four sides to further facilitate different users to hold the entire sample mixing device according to different needs. The bottom of the shell 1 can be in a completely open shape; a bottom plate can also be provided at the bottom of the shell 1 to strengthen the support of the material to be mixed (such as a soil sample) and reduce the risk of accidental damage to the supporting member 5 (the "supporting member 5" can be, for example, a plastic film, kraft paper, etc.) used to support the material to be mixed, resulting in the spillage of the material. In a specific embodiment, as Figure 2 As shown, the bottom plate provided at the bottom of the housing 1 is a hollow structure, for example, a plate with holes ( Figure 2 The sample mixing device can be configured as a single unit (e.g., a long strip of hole in the middle) to provide good support for the material being mixed and reduce the weight of the entire sample mixing device, saving costs. The bottom plate provided at the bottom of the housing 1 and the baffle 101 on the side of the housing 1 can be integrated into a single unit, making the structure of the entire housing 1 more stable. The baffle 101 of the housing 1 is provided with an adsorption block 6 that can be adsorbed by the magnetic strip 4, or the baffle 101 is made of a material that can be adsorbed by the magnetic strip 4 (e.g., iron).

[0039] In actual use, the material to be mixed (such as a soil sample) can be placed on the supporting member 5 (the supporting member 5 can be, for example, a plastic film, kraft paper, etc.), and then the supporting member 5 with the material to be mixed is fixed to the frame of the shell 1. The user holds the grip ring 2 and / or the handle 3 and shakes the entire device to complete the mixing operation of the material to be mixed.

[0040] In one embodiment, Figure 1 and 2As shown, the sample mixing device also includes a magnetic strip 4. In accordance with the magnetic strip 4, the baffle 101 of the shell 1 is made of a material that can be adsorbed by the magnetic strip 4 (e.g., iron). In actual use, the supporting member 5 (e.g., kraft paper) can be first spread flat on the frame of the shell 1, and then the magnetic strip 4 can be pressed on the supporting member 5 (e.g., kraft paper). The magnetic adsorption effect between the magnetic strip 4 and the baffle 101 can be used to tightly fix the supporting member 5 (e.g., kraft paper) in the frame of the shell 1. Then, the material to be mixed (e.g., a soil sample) is placed on the supporting member 5 (e.g., kraft paper). The user then holds the grip ring 2 and / or the handle 3 and shakes the entire device to complete the mixing operation of the material to be mixed. After use, the magnetic strip 4 can be removed to remove the supporting member 5 (such as kraft paper) together with the material to be mixed (such as soil sample) from the frame of the shell 1, and a new supporting member 5 (such as kraft paper) can be replaced to perform the next mixing operation.

[0041] In another embodiment, Figure 3 As shown, in order to facilitate the production of the sample mixing device provided by the present invention, save costs, improve production efficiency, reduce weight and facilitate the use of the sample mixing device in outdoor experiments, the shell 1 can be made of plastic material; the use of plastic material can form the entire shell 1 in one step during the production process, making the entire shell 1 both light and structurally strong. In order to facilitate the use of magnetic strips 4 to fix the supporting member 5 (such as kraft paper) and the material to be mixed, when the shell 1 is made of plastic material, such as Figure 3 As shown, a plurality of grooves 102 can be provided on the inner side of the baffle 101 on the side of the shell 1; an adsorption block 6 can be embedded and installed in each of the grooves 102, wherein the adsorption block 6 is made of a material that can be adsorbed by a magnet (such as iron).

[0042] Further, if Figure 3 As shown, the magnetic strip 4 can also be made into an integrated structure that matches the inner side of the housing 1 (for example Figure 3 As shown, the shape is consistent with the quadrilateral formed by the baffles on the side of the housing 1), so that the magnetic strip 4 forms a whole. Figure 3 As shown, a handle 401 may be provided on the top of the overall structure formed by the magnetic strip 4 to facilitate taking and placing the magnetic strip 4 ; there may be two handles 401 , provided on the top of two opposite sides of the overall structure formed by the magnetic strip 4 .

[0043] In another specific embodiment, the shell 1 is made of a soft, deformable material such as silicone, and the entire shell 1 including the baffle 101 is integrally formed, so that the structure of the entire shell 1 forms a whole and is strong and lightweight. The bottom of the shell 1 is a hollow structure or a concave funnel shape. A plurality of grooves 102 are provided on the inner side of the baffle 101 on the side of the shell 1; an adsorption block 6 can be embedded and fixedly installed in each of the grooves 102, wherein the adsorption block 6 is made of a material that can be adsorbed by a magnet (such as iron). The supporting member 5 is made of a soft, deformable material, such as a plastic film or kraft paper. When using the sample mixing device, first place the supporting member 5 (such as a plastic film or kraft paper) in the frame of the shell 1, and keep a certain degree of looseness in the middle part of the supporting member 5 so that after the material (such as a soil sample) is added, it can sag under the pressure of the material to form a depression; then use the magnetic strip 4 to fix the edge of the supporting member 5 to the inner side of the baffle 101, and then place the material on the supporting member 5, so that the supporting member 5 naturally sinks under the pressure of the material and mixes the material into a ball; the user then shakes the entire device by holding the grab ring 2 and / or handle 3; since the shell 1 is soft and deformable, during the shaking process, the material can roll back and forth on the supporting member 5 as the entire device shakes, so that the material can be mixed faster and more fully.

[0044] The sample mixing device provided by the utility model has a simple and reliable structure, low cost, and is easy to use. By arranging a baffle 101 at the edge of the shell 1, the problem of spillage of the material to be mixed (such as a soil sample) is effectively avoided, and the problem of frequent scratching of the kraft paper when directly using it, resulting in sample spillage and inability to effectively complete the mixing operation, is avoided. In addition, the sample mixing device has a firm structure and is particularly suitable for mixing a large amount of material (more than 5 kg), especially for mixing samples such as fertilizers and soils to be tested. It is simple, practical, easy to carry, and greatly improves work efficiency.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
