Description

Technical Field

[0001] This application relates to the field of laboratory soil pretreatment equipment technology, and in particular to a detachable rapid mixing device for laboratory soil. Background Technology

[0002] In laboratory soil-related studies (such as soil fertility analysis and crop growth simulation), it is often necessary to mix soil with various additives (such as nutrient solutions and amendments) in precise proportions, and the uniformity of the mixture directly affects the accuracy and reliability of the experimental data. During laboratory soil-related research, a rapid soil mixing device is an indispensable small-scale experimental instrument. This device can be used to uniformly mix soil and additives before pot experiments.

[0003] In existing technologies, traditional rapid soil mixing devices in laboratories mostly rely on two types of equipment: one is simple manual stirring tools (such as glass rods, stirring spoons, etc.). These tools require manual operation for mixing, and the mixing process is highly dependent on the operator's experience and physical strength, which is time-consuming and laborious. It is difficult to ensure the uniform distribution of additives and soil, and it is easy to produce problems of local concentrations that are too high or too low, which seriously affects the scientificity and accuracy of experimental results. The other type is electric stirring devices. Although they can improve the mixing efficiency, they lack coordinated control over the feeding process. If the required proportion of soil and additives are poured into the mixing container at once, the instantaneous accumulation of materials can easily lead to the problem of sufficient mixing in the center and insufficient mixing at the edges, making it impossible to achieve uniform mixing in all directions and dimensions. This increases the risk of deviation in experimental data. Moreover, electric stirring devices are not easy to clean. Since laboratory soil experiments often require the use of different soil samples or additive types, mixing different samples in the same container can easily cause cross-contamination between samples, affecting the accuracy of experimental data.

[0004] Therefore, we propose a detachable laboratory soil rapid mixing device to solve the above problems. Utility Model Content

This facilitates cleaning not only the inside of the mixing cylinder, but also the soil feeding hopper, additive feeding hopper, and mixing mechanism, effectively preventing cross-contamination of subsequent experiments by residual soil or additives, and meeting the strict requirements of laboratory equipment cleanliness.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a detachable laboratory soil rapid mixing device, comprising a support frame placed and fixed in a laboratory, a fixing sleeve fixedly installed on the top of the support frame, the top and bottom of the fixing sleeve being open structures, a mixing cylinder detachably installed and fixed inside the fixing sleeve, the top and bottom of the mixing cylinder extending outside the fixing sleeve, the top of the mixing cylinder being open structures, a hydraulic cylinder fixedly installed on the top left side of the support frame, a connecting ear plate fixedly installed on the output shaft end of the hydraulic cylinder, a cylinder cover fixedly connected on the right side of the connecting ear plate, the cylinder cover abutting against the top surface of the mixing cylinder, a soil feeding hopper and an additive feeding hopper fixedly installed on the top of the cylinder cover, the bottom ends of the soil feeding hopper and the additive feeding hopper extending into the mixing cylinder, and a stirring mechanism provided on the cylinder cover, the stirring mechanism being used to stir and mix the soil and additives evenly.

[0007] A further provision of this application is that the bottom inner diameter of the soil feeding hopper is larger than the bottom inner diameter of the additive feeding hopper.

[0008] A further configuration of this application is as follows: the mixing mechanism includes a vertical shaft, a motor, multiple mixing rods, multiple mixing blades, and a disc. The vertical shaft is rotatably mounted at the bottom center of the cylinder cover. The motor is fixedly mounted on the top of the cylinder cover via a frame. The top end of the vertical shaft passes through the cylinder cover and is fixedly connected to the output shaft end of the motor. Multiple mixing rods are fixedly mounted on the vertical shaft and are evenly distributed. Multiple mixing blades are fixedly mounted on multiple mixing rods and are evenly distributed. The disc is fixedly sleeved on the vertical shaft and located above the mixing rods. The bottom ends of the soil feeding hopper and the additive feeding hopper are both in contact with the top surface of the disc. The top of the disc has three equally spaced, annularly distributed soil discharge holes. The bottom end of the soil feeding hopper is connected to one of the soil discharge holes. The top of the disc has two symmetrically arranged additive discharge holes. The bottom end of the additive feeding hopper is connected to one of the additive discharge holes.

[0009] A further feature of this application is that a circular hole is provided at the center of the top of the cylinder cover, and a bearing is fixedly sleeved on the vertical shaft, with the outer ring of the bearing being fixedly connected to the inner wall of the circular hole.

[0010] A further feature of this application is that the bottom end of the soil feeding hopper, the bottom end of the additive feeding hopper, and the top surface of the disc are all smooth flat surfaces.

[0011] A further feature of this application is that: four positioning grooves are provided on the inner wall of the fixed sleeve in an equally spaced annular arrangement, and the top of each of the four positioning grooves is open; four positioning blocks are fixedly installed on the outer wall of the mixing cylinder in an equally spaced annular arrangement, and the four positioning blocks are slidably installed in their respective positioning grooves.

[0012] A further feature of this application is that the bottom inner wall of the mixing cylinder has a centrally concave arc-shaped surface structure, and a discharge pipe is fixedly connected to the center of the bottom of the mixing cylinder, with an end cap threaded onto the bottom end of the discharge pipe.

[0013] A further feature of this application is that a plunger is fixedly installed inside the end cap, and the top end of the plunger slides through the discharge pipe.

[0014] A further feature of this application is that the mixing cylinder is made of transparent tempered glass.

[0015] A further feature of this application is that a wear-resistant sealing ring is fixedly sleeved on the outer side wall of the disc, and the outer ring of the wear-resistant sealing ring is rotatably sealed to the inner side wall of the mixing cylinder.

[0016] This application includes at least one of the following beneficial technical effects:

[0017] 1. This application utilizes a mixing mechanism to achieve all-round, multi-dimensional mixing of soil and additives, avoiding dead zones where mixing is insufficient, and improving the uniformity and efficiency of mixing. By utilizing the continuous rotation of the disc following the vertical axis, intermittent feeding can be formed under the synergistic effect of the soil feeding hole and the additive feeding hole, effectively avoiding uneven mixing caused by excessive feeding at one time. Furthermore, the bottom inner diameter of the soil feeding hopper is designed to be larger than that of the additive feeding hopper, which can achieve a greater amount of soil added per unit time than the amount of additive added, which can help to achieve uniform mixing of soil and additives.

[0018] 2. This application, by controlling the extension of the hydraulic cylinder, can lift the cylinder cover, soil hopper, additive hopper, and mixing mechanism to a suitable height. Then, the mixing cylinder is lifted vertically upwards, causing the four positioning blocks on the mixing cylinder to slide out of their corresponding positioning slots, thus allowing the mixing cylinder to be disassembled and removed. This facilitates cleaning of the inside of the mixing cylinder, as well as cleaning of the soil hopper, additive hopper, and mixing mechanism. It effectively avoids cross-contamination of subsequent experiments by residual soil or additives, meeting the strict requirements of the laboratory for equipment cleanliness.

[0019] 3. This application completes the initial installation and positioning of the mixing cylinder by inserting the mixing cylinder into the fixing sleeve from top to bottom and allowing the four positioning blocks to slide into their respective positioning slots. Finally, the hydraulic cylinder is controlled to retract and reset, driving the connecting ear plate, cylinder cover, and stirring mechanism to descend vertically until the cylinder cover descends to abut against the top of the mixing cylinder. The cylinder cover can then be used to press and fix the mixing cylinder onto the fixing sleeve, thus achieving rapid installation and fixing of the mixing cylinder. Attached Figure Description

[0027] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] See Figures 1-6This application provides a detachable laboratory soil rapid mixing device, including a support frame 1 fixed in a laboratory. A fixing sleeve 2 is fixedly installed on the top of the support frame 1. The top and bottom of the fixing sleeve 2 are open. A mixing cylinder 3 is detachably installed and fixed inside the fixing sleeve 2. The top and bottom of the mixing cylinder 3 extend outside the fixing sleeve 2. The top of the mixing cylinder 3 is open, and the inner wall of the mixing cylinder 3 is smooth. A hydraulic cylinder 4 is fixedly installed on the top left side of the support frame 1. A connecting ear plate 5 is fixedly installed on the output shaft end of the hydraulic cylinder 4. A cylinder cover 6 is fixedly connected to the right side of the connecting ear plate 5. The connecting ear plate 5 and the cylinder cover 6 are integrally formed. The cylinder cover 6 abuts against the top surface of the mixing cylinder 3. The inner wall of the fixing sleeve 2... Four equally spaced annular positioning slots 10 are provided, and the tops of the four positioning slots 10 are all open. Four equally spaced annular positioning blocks 11 are fixedly installed on the outer wall of the mixing cylinder 3. The four positioning blocks 11 are slidably installed in the corresponding positioning slots 10. The hydraulic cylinder 4 is used to control the vertical lifting of the connecting ear plate 5 and the cylinder cover 6. By utilizing the sliding connection between the four positioning blocks 11 and the corresponding positioning slots 10, and cooperating with the control of the hydraulic cylinder 4 to extend or retract and reset, the mixing cylinder 3 can be disassembled and installed. The mixing cylinder 3 can be quickly disassembled and installed without complicated tools, which facilitates the thorough cleaning of the inner wall of the mixing cylinder 3 and avoids cross-contamination of subsequent experiments by residual soil or additives.

[0029] In this embodiment, a soil feeding hopper 7 and an additive feeding hopper 8 are fixedly installed on the top of the cylinder cover 6. The bottom ends of both the soil feeding hopper 7 and the additive feeding hopper 8 extend into the mixing cylinder 3. The soil feeding hopper 7 is used to add the soil required for the experiment into the mixing cylinder 3, and the additive feeding hopper 8 is used to add the additives required for the experiment into the mixing cylinder 3. The bottom inner diameter of the soil feeding hopper 7 is larger than the bottom inner diameter of the additive feeding hopper 8, which can achieve a soil addition amount greater than the additive addition amount per unit time, which helps to achieve uniform mixing of soil and additives.

[0030] In this embodiment, a stirring mechanism 9 is provided on the cylinder cover 6. The stirring mechanism 9 is used to stir and mix the soil and additives. The stirring mechanism 9 includes a vertical shaft 91, a motor 92, multiple stirring rods 93, multiple stirring blades 94, and a disc 95. The vertical shaft 91 is rotatably mounted at the bottom center of the cylinder cover 6. The motor 92 is fixedly mounted on the top of the cylinder cover 6 via a frame. The top end of the vertical shaft 91 passes through the cylinder cover 6 and is fixedly connected to the output shaft end of the motor 92. Multiple stirring rods 93 are fixedly mounted on the vertical shaft 91 and are evenly distributed. Multiple stirring blades 94 are fixedly mounted on multiple stirring rods 93 and are evenly distributed. The disc 95 is fixedly sleeved on the vertical shaft. Located above the stirring rod 93, the bottom ends of the soil feeding hopper 7 and the additive feeding hopper 8 are in contact with the top surface of the disc 95. The top of the disc 95 has three equally spaced, annularly distributed soil discharge holes 96. The bottom end of the soil feeding hopper 7 is connected to one of the soil discharge holes 96. The top of the disc 95 has two symmetrically arranged additive discharge holes 97, and the bottom end of the additive feeding hopper 8 is connected to one of the additive discharge holes 97. The motor 92 controls the rotation of the vertical shaft 91, causing the multiple stirring rods 93, multiple stirring blades 94, and the disc 95 to rotate with the vertical shaft 91. The multiple stirring rods 93 are equipped with... With the combined action of multiple mixing blades 94, the soil and additives in the mixing drum 3 can be mixed in an all-round and multi-dimensional manner, avoiding dead zones where the mixing is insufficient. By designing that the bottom ends of the soil feeding hopper 7 and the additive feeding hopper 8 are in contact with the top surface of the disc 95, when the disc 95 rotates synchronously with the vertical shaft 91, the soil and additives enter the mixing drum 3 through the soil discharge hole 96 and the additive discharge hole 97 on the disc 95, respectively. The rotating disc 95 can form an intermittent discharge effect, effectively avoiding uneven mixing caused by excessive material added at one time during the feeding process, and further ensuring that the soil and additives are mixed according to the experimental preset ratio. Compared to precise input, this further ensures uniform mixing of soil and additives and improves the reliability of experimental data. The bottom ends of the soil hopper 7, the additive hopper 8, and the top surface of the disc 95 are all smooth flat surfaces. The diameter of the soil discharge hole 96 is larger than the inner diameter of the bottom end of the soil hopper 7 and smaller than the outer diameter of the bottom end of the soil hopper 7, thus ensuring that all soil falls smoothly through the soil discharge hole 96. The diameter of the additive discharge hole 97 is larger than the inner diameter of the bottom end of the additive hopper 8 and smaller than the outer diameter of the bottom end of the additive hopper 8, thus ensuring that all additives fall smoothly through the additive discharge hole 97.

[0031] In this embodiment, a circular hole is provided at the center of the top of the cylinder cover 6, and a bearing is fixedly sleeved on the vertical shaft 91. The outer ring of the bearing is fixedly connected to the inner wall of the circular hole to ensure the stability and smoothness of the vertical shaft 91 when it rotates.

[0032] In this embodiment, the bottom inner wall of the mixing cylinder 3 is an arc-shaped structure with a concave center. A discharge pipe 12 is fixedly connected to the bottom center of the mixing cylinder 3. An end cap 13 is threaded onto the bottom end of the discharge pipe 12 to facilitate the discharge of the uniformly mixed soil and additive mixture inside the mixing cylinder 3.

[0033] In this embodiment, a plunger 14 is fixedly installed inside the end cap 13. The top end of the plunger 14 slides through the discharge pipe 12. The plunger 14 is used to seal the inside of the discharge pipe 12. During the mixing process, soil and additives can be prevented from entering the discharge pipe 12, further eliminating the dead corners of the mixing.

[0034] In this embodiment, the mixing cylinder 3 is made of transparent tempered glass. The design of the mixing cylinder made of transparent tempered glass allows the experimenter to observe the mixing state of the materials inside the mixing cylinder 3 in real time. At the same time, the tempered glass material has both high strength and corrosion resistance, meeting the long-term use requirements of the laboratory.

[0035] In this embodiment, a wear-resistant sealing ring 98 is fixedly sleeved on the outer wall of the disc 95. The outer ring of the wear-resistant sealing ring 98 rotates and seals with the inner wall of the mixing cylinder 3. The design of the wear-resistant sealing ring 98 can effectively seal the gap between the disc 95 and the inner wall of the mixing cylinder 3, effectively preventing soil particles or additive powder from splashing upward from the gap between the disc and the inner wall of the mixing cylinder 3 during the mixing process. This avoids material waste, keeps the experimental environment clean, and reduces the impact of dust on the operators.

[0036] In this embodiment, both the hydraulic cylinder 4 and the motor 92 are commercially available, and their wiring connection and control methods are mature technologies in the field and have been fully disclosed, so they will not be described again in this article.

[0037] With the above structure, the detachable laboratory soil rapid mixing device provided in this application, when in use, starts the motor 92, and the output shaft of the motor 92 drives the vertical shaft 91 to rotate. When the vertical shaft 91 rotates, it simultaneously drives multiple stirring rods 93, stirring blades 94 on the stirring rods 93, and the disc 95 to rotate. At this time, the pre-weighed and proportioned soil is poured into the soil feeding hopper 7, and the pre-weighed and proportioned additives are poured into the additive feeding hopper 8. As the disc 95 continues to rotate, the bottom of the soil feeding hopper 7 sequentially contacts three soil droplets. Hole 96 is intermittently connected, and the bottom of the additive feeding hopper 8 is intermittently connected to two additive discharge holes. Soil and additives will enter the mixing cylinder 3 through the soil discharge hole 96 and the additive discharge hole 97 respectively, which can form intermittent discharge, effectively avoiding uneven mixing caused by excessive feeding at one time. In addition, the bottom inner diameter of the soil feeding hopper 7 is designed to be larger than the bottom inner diameter of the additive feeding hopper 8, which can achieve a soil addition amount greater than the additive addition amount per unit time, thus helping to achieve uniform mixing of soil and additives.

[0038] As soil and additives fall into the bottom of the mixing drum 3, the rotation of multiple stirring rods 93 can be used to stir the soil and additive materials in the mixing drum 3 laterally. The rotation of multiple stirring blades 94 can be used to cut and stir the soil and additive materials, break up material agglomerates, improve the fineness of the soil and additive mixture, and thus achieve all-round and multi-dimensional mixing of soil and additives, avoiding dead corners where the mixture is not fully mixed.

[0039] During the mixing process, the mixing cylinder 3 is made of transparent tempered glass, allowing the experimenters to observe the mixing state of the soil and additive materials inside the mixing cylinder 3 in real time. After the soil and additive materials are mixed evenly, the motor 92 is stopped, and the end cap 13 with threads installed at the bottom of the discharge pipe 12 is rotated. This causes the end cap 13 to drive the plunger 14 vertically downwards from the discharge pipe 12, thus releasing the blockage on the discharge pipe 12. The evenly mixed soil and additive materials are then smoothly discharged from the discharge pipe 12 under the action of gravity, thus completing the discharge operation.

[0040] After the material is discharged, the hydraulic cylinder 4 is extended to push the connecting ear plate 5 and the cylinder cover 6 to rise vertically. The cylinder cover 6 is separated from the top of the mixing cylinder 3, so that the soil feeding hopper 7, the additive feeding hopper 8 and the stirring mechanism 9 rise with the cylinder cover 6 until the bottom end of the vertical shaft 91 in the stirring mechanism 9 moves out of the mixing cylinder 3 and reaches a suitable distance from the upper surface of the fixing sleeve 2. Then, the hydraulic cylinder 4 is stopped. Subsequently, the mixing cylinder 3 is lifted vertically upward, so that the four positioning blocks 11 on the mixing cylinder 3 slide out of the corresponding positioning grooves 10. The mixing cylinder 3 can then be disassembled and removed. After disassembly, the inside of the mixing cylinder 3 can be cleaned, and the soil feeding hopper 7, the additive feeding hopper 8 and the stirring mechanism 9 can also be cleaned. This effectively avoids cross-contamination of subsequent experiments by residual soil or additives and meets the strict requirements of the laboratory for equipment cleanliness.

[0041] After cleaning, insert the mixing cylinder 3 into the fixing sleeve 2 from top to bottom, and align the four positioning blocks 11 with the corresponding positioning grooves 10. Let the four positioning blocks 11 slide into the corresponding positioning grooves 10, thus completing the initial installation and positioning of the mixing cylinder 3. Finally, control the hydraulic cylinder 4 to retract and reset, driving the connecting ear plate 5, the cylinder cover 6 and the stirring mechanism 9 to descend vertically until the cylinder cover 6 descends to abut against the top of the mixing cylinder 3. Stop the operation of the hydraulic cylinder 4, and use the cylinder cover 6 to press and fix the mixing cylinder 3 onto the fixing sleeve 2, thus completing the quick installation and fixing of the mixing cylinder 3.
