Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically to a soil testing dryer. Background Technology

[0002] Soil environmental monitoring refers to important measures for understanding the status of soil environmental quality. It aims to prevent and control soil pollution hazards by dynamically analyzing and measuring the degree and development trend of soil pollution. It includes current status surveys of soil environmental quality, surveys of regional soil environmental background values, investigations of soil pollution incidents, and dynamic observation of polluted soil. Soil environmental monitoring generally includes steps such as preparation, site selection, sampling, sample preparation, analysis and testing, and evaluation. To improve the accuracy of soil testing and analysis, soil samples often need to be rapidly dried before testing. Since the collected soil samples are in lumps, the drying efficiency is slow. Therefore, the soil samples need to be crushed during the drying process. However, existing soil testing drying devices do not crush the samples sufficiently and cannot significantly improve the drying efficiency. To address this issue, we propose a soil testing dryer. Utility Model Content

The soil sample entering the drying chamber is crushed by the crushing roller module and then falls into the pulverizing module for further pulverization. After pulverization, the soil sample falls into the storage box, where the heating pad dries the soil sample.

[0004] Preferably, the pulverizing module includes a pulverizing motor, an eccentric wheel, a filter cylinder, a pulverizing block, a rotating shaft, a swing arm, and a chute.

The connecting end of the eccentric wheel is engaged inside the chute, and the rotation of the connecting end of the eccentric wheel is restricted by the chute.

[0005] Preferably, the end of the crushing block is formed with an arc-shaped protrusion, the two ends of the arc-shaped protrusion are upturned, and the middle part of the arc-shaped protrusion is closely fitted with the inside of the filter cylinder.

[0006] Preferably, the filter cylinder has a feed inlet at the top and several sets of filter holes at the bottom, which are arranged in layers with equal spacing.

[0007] Preferably, a screening module is provided between the crushing roller module and the pulverizing module. The screening module includes a base, two sets of rotating rods, a filter frame, a connecting rod, a screening motor, and a cam. The base is located in the middle of the interior of the drying chamber. The two sets of rotating rods are symmetrically arranged on both sides of the surface of the base. The base is rotatably connected to the drying chamber through the rotating rods. The filter frame is located on the top of the rotating rod surface. The connecting rod is located on the surface of the base. The screening motor is located on one side of the interior of the drying chamber. The cam is located at the output end of the screening motor. One end of the connecting rod is mounted on the surface of the cam.

[0008] Preferably, the screening module further includes a cover plate and bolts.

[0012] This utility model also includes a base, two sets of rotating rods, a filter frame, a connecting rod, a screening motor, and a cam. When the screening motor is started, it causes the cam to rotate. The rotation of the cam causes the filter frame to be lifted and lowered repeatedly, thereby screening and filtering the soil sample inside the filter frame. Large pieces of soil that are not completely crushed and impurities are left inside the filter frame. This allows for secondary crushing of the soil sample, which is convenient for subsequent pulverization. At the same time, it can screen out impurities in the soil sample, thereby improving the purity of the soil sample. Attached Figure Description

[0015] The technical solution of this utility model will now be clearly and completely described with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are merely one embodiment of this utility model, and not all embodiments. Based on this embodiment, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Specific embodiments are as follows: A soil dryer for testing, such as Figures 1-8 The drying chamber 1 includes a feeding hopper 10 on the top surface of the drying chamber 1, a crushing roller module 2 below the feeding hopper 10, a heating pad 3 at the bottom inside the drying chamber 1, a storage box 4 on the top surface of the heating pad 3, an upper box cover 5 and a lower box cover 6 on the two sides of the surface of the drying chamber 1, and a crushing module 7 below the crushing roller module 2. After entering the drying chamber 1, the soil sample is crushed by the crushing roller module 2 and then falls into the crushing module 7 for further crushing. After crushing, the soil sample falls into the storage box 4, and the heating pad 3 dries the soil sample in the storage box 4.

[0016] The pulverizing module 7 includes a pulverizing motor 71, an eccentric wheel 72, a filter cylinder 73, pulverizing blocks 74, a rotating shaft 75, a swing arm 76, and a chute 77. The pulverizing motor 71 is located inside one side of the drying chamber 1, the eccentric wheel 72 is located at the output end of the pulverizing motor 71, the filter cylinder 73 is located at the lower end of the drying chamber 1, the pulverizing blocks 74 are located inside the filter cylinder 73, the rotating shaft 75 is located at one end of the pulverizing blocks 74, the swing arm 76 is located at one end of the rotating shaft 75, and a chute 77 is formed on the surface of the swing arm 76. The connecting end of the eccentric wheel 72 is engaged inside the chute 77, and the rotation of the connecting end of the eccentric wheel 72 is restricted by the chute 77. A feed inlet is located directly above the filter cylinder 73, and several sets of filters are located directly below the filter cylinder 73. The filter has several sets of filter holes arranged in layers with equal spacing. When in use, the crushing motor 71 is started, which causes the eccentric wheel 72 to start rotating. Since the sliding groove 77 limits the connection end of the eccentric wheel 72, the connection end of the eccentric wheel 72 slides along the sliding groove 77 while rotating. At the same time, the eccentric wheel 72 causes the swing arm 76 to swing left and right. The crushing block 74 swings synchronously under the drive of the swing arm 76. During the swinging process of the crushing block 74, the soil sample in the filter cylinder 73 is further crushed. The fully crushed soil sample falls into the storage box 4 through the filter hole at the bottom of the filter frame 83. The heating pad 3 dries the small particles of soil sample in the storage box 4, which can greatly improve the drying efficiency of the dryer.

[0017] The end of the crushing block 74 is formed with an arc-shaped protrusion. The two ends of the arc-shaped protrusion are upturned, and the middle part of the arc-shaped protrusion fits tightly against the inside of the filter cylinder 73. During the swinging process of the crushing block 74, the middle part of the arc-shaped protrusion at the end of the crushing block 74 slides against the inner wall of the filter cylinder 73. Through the cooperation between the arc-shaped protrusion at the end of the crushing block 74 and the filter cylinder 73, the soil sample in the filter cylinder 73 is crushed. The upturned ends of the arc-shaped protrusion at the end of the crushing block 74 can bring the soil sample into the bottom of the crushing block 74, thereby facilitating the crushing of the soil sample by the arc-shaped protrusion at the end of the crushing block 74.

[0018] A screening module 8 is provided between the crushing roller module 2 and the crushing module 7. The screening module 8 includes a base 81, two sets of rotating rods 82, a filter frame 83, a connecting rod 86, a screening motor 87, and a cam 88. The base 81 is located in the middle of the interior of the drying chamber 1. The two sets of rotating rods 82 are symmetrically arranged on both sides of the surface of the base 81. The base 81 is rotatably connected to the drying chamber 1 through the rotating rods 82. The filter frame 83 is mounted on the top of the surface of the rotating rods 82. The connecting rod 86 is located on the surface of the base 81. The screening motor 87 is located on one side of the interior of the drying chamber 1. The cam 88 is located at the output end of the screening motor 87. One end of the connecting rod 86 is mounted on the surface of the cam 88. In use, the screening motor 87 is started, which causes the cam 88 to start rotating. When the cam 88 rotates, the cam 88 rotates. When the protrusion of wheel 88 rotates to its highest point, cam 88 lifts one end of connecting rod 86. Under the drive of connecting rod 86, base 81 rotates around rotating rod 82. Filter frame 83 on top of base 81 rotates synchronously. When the protrusion of cam 88 rotates to its lowest point, base 81 rotates downwards around rotating rod 82 under its own weight and the weight of the soil sample in filter frame 83 until connecting rod 86 falls onto the surface of cam 88. The rotation of cam 88 repeatedly lifts and lowers filter frame 83, thereby screening and filtering the soil sample in filter frame 83. Large pieces of soil that are not completely crushed and impurities remain inside filter frame 83. This allows for secondary crushing of the soil sample, facilitating subsequent pulverization, and also allows for the screening out of impurities, thereby improving the purity of the soil sample.

[0019] The screening module 8 also includes a cover plate 84 and bolts 85. The cover plate 84 is disposed on one side of the surface of the base 81, and two sets of bolts 85 are respectively disposed on both sides of the surface of the cover plate 84. The cover plate 84 is fixedly connected to the base 81 by the bolts 85. The cover plate 84 is fixed to one side of the base 81 by the cooperation of the two sets of bolts 85, which plays a limiting role in the filter frame 83, making the filter frame 83 more stable during rotation and preventing the filter frame 83 from slipping out of the base 81.

[0020] The screening module 8 includes a limiting groove 89, which is formed at the bottom of the surface of the connecting rod 86. The inner wall of the limiting groove 89 abuts against the surface of the cam 88. The limiting groove 89 limits the cam 88, so that as the cam 88 lifts the connecting rod 86, the surface of the cam 88 rolls along the limiting groove 89, making the contact between the cam 88 and the connecting rod 86 more stable.

[0021] The drying chamber 1 has two sets of collection frames 9 inside, which are located above and below the screening module 8, respectively. The lower opening of the collection frame 9 is smaller than the upper opening of the collection frame 9. After the soil sample is processed, it falls into the interior of the collection frame 9 and then falls from the bottom of the collection frame 9. Both sets of collection frames 9 play a role in collecting the soil sample, while reducing the area of ​​the outlet of the collection frame 9, so that the soil sample can fall accurately into the interior of the structure below.

[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
