Description

Technical Field

[0001] This utility model relates to the field of soil pretreatment technology, and in particular to a soil sample surface impurity crushing pretreatment device. Background Technology

[0002] The topsoil is the most active area for interaction between soil, atmosphere, plants, and microorganisms. Its material composition directly reflects soil quality and ecological environment. Testing can assess soil fertility, guide agricultural production, monitor soil pollution, and analyze soil physicochemical properties.

[0003] Currently, testing is usually performed directly on the soil surface. However, the soil surface itself has a certain degree of hardness, which can easily lead to insufficient contact between the testing reagent and the soil sample. This results in the testing reagent being unable to penetrate, the target substance not being fully dissolved, and the final test value being far lower than the true value. At the same time, hard impurities themselves are difficult to react with the reagent, which will dilute the concentration of effective components, further amplifying the deviation in the results. The results cannot reflect the physical state of the soil itself, and the data loses its reference value. In view of this, this utility model is proposed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Reference Figures 1-5 A soil sample surface impurity crushing and pretreatment device includes a housing 1, an inlet 101 at the top of the housing 1, and an outlet 102 at the bottom of the housing 1; a sliding block 2 is slidably disposed inside the housing 1, and a sliding serrated blade 201 is provided on the sliding block 2; a fixed block 3 is fixedly disposed on the inner wall of the housing 1, and a fixed serrated blade 301 that cooperates with the sliding serrated blade 201 is provided on the outer wall of the fixed block 3; a baffle 4 is also slidably disposed inside the housing 1, and the baffle 4 is positioned below the sliding block 2 and the fixed block 3.

[0028] In this invention, during use, the surface impurities of the soil sample to be crushed are placed into the housing 1 through the feed inlet 101. The surface impurities of the soil sample are placed between the fixed block 3 and the sliding block 2. Then, the sliding block 2 is controlled to drive the sliding serrated blade 201 to move, so that it cooperates with the fixed serrated blade 301 to achieve the crushing of the surface impurities of the soil sample. When the sliding serrated blade 201 and the fixed serrated blade 301 are in contact, a squeezing force is generated between them, thereby crushing the surface impurities of the soil sample to achieve the purpose of pretreatment, so that the detection effect of the surface impurities of the soil sample is better in the subsequent detection process.

[0029] Reference Figure 4 and Figure 5 The sliding block 2 has integrally formed partitions 202 on both outer walls. The fixed block 3 is placed between the two partitions 202. The outer walls of the two partitions 202 are provided with protrusions 204. The outer wall of the box 1 is provided with sliding holes 108. The partitions 202 and protrusions 204 are slidably connected in the sliding holes 108.

[0030] When the sliding block 2 moves the sliding saw blade 201, the partition 202 will slide on the outer wall of the fixed block 3, thereby forming a closed space between the fixed block 3 and the sliding block 2, which can better achieve the effect of crushing the items located between them. In addition, the sliding hole 108 can make the partition 202 slide more stably, thereby making the movement of the sliding block 2 more stable and convenient to use.

[0031] Reference Figures 1-3 The outer wall of the box 1 is provided with a first slide groove 105, a second slide groove 106 and a third slide groove 107 respectively. The outer wall of the partition 202 is provided with a slide plate 203 and a first moving block 205. The slide plate 203 is slidably connected in the first slide groove 105 and the first moving block 205 is slidably connected in the second slide groove 106.

[0032] Reference Figures 1-5 The box 1 is fixedly connected to a fixed plate 401 corresponding to the baffle 4. In the initial state, the baffle 4 and the fixed plate 401 abut against each other. The outer wall of the baffle 4 is provided with a second moving block 402, and the second moving block 402 is slidably connected to the third sliding groove 107.

[0033] Reference Figures 1-5 Two sets of mounting bases 5 are also fixedly installed on the outer wall of the housing 1. A motor 501 is installed on the mounting base 5. The output end of the motor 501 is provided with a bidirectional threaded rod 502. The bidirectional threaded rod 502 is threadedly connected to the slide plate 203 on one of the partitions 202.

[0034] In this invention, when in use, starting the motor 501 causes the bidirectional threaded rod 502 at the output end to rotate. It should be noted that each of the two partitions 202 has a sliding plate 203 on its outer wall, and the two sliding plates 203 are respectively located on both sides of the housing 1. Mounting seats 5 are provided on both sides of the housing 1, and each mounting seat 5 has a bidirectional threaded rod 502 and a limiting rod. When the motor 501 is started, it drives the bidirectional threaded rod 502 to rotate and thread it onto the sliding plate 203, thereby moving the sliding plate 203 on that side. Simultaneously, the sliding plate 203 on the other side slides along the limiting rod, achieving a limiting effect. When the sliding plate 203 moves, it drives the sliding block 2 and the sliding serrated blade 201 to move, cooperating with the fixed serrated blade 301 to achieve the crushing operation. Furthermore, the bidirectional threaded rod 502 allows the sliding plate 203 to reciprocate cyclically on it, facilitating repeated crushing.

[0035] Reference Figures 1-5 An auxiliary gear 206 is rotatably connected to the outer wall of the housing 1. The first moving block 205 and the second moving block 402 are each provided with a rack plate that meshes with the auxiliary gear 206. The first moving block 205 and the second moving block 402 are respectively located at the upper and lower ends of the auxiliary gear 206.

[0036] In this invention, during the process of the sliding block 2 moving driven by the sliding plate 203, the sliding block 2 also drives the first moving block 205 to move within the second sliding groove 106. When the rack plate on the first moving block 205 moves to mesh with the auxiliary gear 206, it will cause the auxiliary gear 206 to rotate and mesh with the rack plate on the second moving block 402 at its bottom, thereby driving the second moving block 402 to slide within the third sliding groove 107, thus causing the baffle 4 to move. At this time, the crushed material will fall through the gap between the baffle 4 and the fixed plate 401. In the initial state, the baffle 4 and the fixed plate 401 abut against each other, which can support the input material and prevent it from falling directly. This repeated operation can improve the crushing effect.

[0037] Reference Figures 1-3 The bottom of the discharge section 102 is inclined, and the bottom of the discharge section 102 is provided with a receiving trough 103 to cooperate with it. The bottom of the box body 1 is provided with a support leg 104. The material discharged between the baffle 4 and the fixed plate 401 will be discharged through the discharge section 102. The inclined setting of the discharge section 102 can avoid the residue of crushed material and make it easy to discharge. After discharge, the material will enter the receiving trough 103. The support leg 104 can achieve the support effect of the box body 1.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
