Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soil grinders, in particular to a replaceable roller soil grinder. Background Art
[0002] When conducting soil testing, soil samples need to be crushed for sample preparation, but soil sample preparation is very time-consuming and labor-intensive. First, the soil samples are air-dried, and then large pieces of soil are ground after air-drying. The larger pieces of soil after air-drying are difficult to crush during the manual grinding process. Since the metal content of the soil is to be tested, metal sample preparation tools are avoided during sample preparation. Each soil sample needs to be manually smashed with a rubber hammer and a wooden hammer, and the soil pieces need to be crushed with a wooden stick, which is time-consuming, labor-intensive, and inefficient. At the same time, during manual grinding, the dust in the air will also cause certain harm to the operator.
[0003] In summary, the crushing of soil samples and the rough grinding of samples after air drying require a lot of manual time, which seriously restricts the efficiency of soil testing. Therefore, a replaceable drum soil grinder is proposed to solve the above problems. Utility Model Content
[0004] The utility model aims to provide a replaceable drum soil grinder, comprising a reduction motor, a motor reduction box is arranged at the rear end of the reduction motor, the rear end of the motor reduction box is connected to a connecting shaft through a coupling, the connecting shaft transversely penetrates a bearing seat, and extends to the inside of a grinding cylinder to be connected to a grinding blade, a hexagonal nut is arranged at the part of the connecting shaft located inside the grinding cylinder, a rear cover is arranged at the rear end of the grinding cylinder, and the upper part of the rear cover is connected to a silo.
[0005] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0006] The utility model provides a reduction motor and a motor reduction box, and the reduction motor and the motor reduction box are combined into a reduction motor speed gear box. The reduction motor speed gear box drives the connecting shaft to rotate through a coupling, and then drives the grinding blade to rotate in the grinding cylinder. The rolling speed is properly adjusted to fully simulate the grinding of soil samples. After the sample is stirred, the grinding cylinder is removed and the soil is poured through a 10-mesh sieve to obtain a sample to be tested. The speed can be adjusted according to the characteristics of the soil sample. While not affecting the sample crushing effect, a lot of manpower is saved and work efficiency is improved.
[0007] When grinding a plurality of soil samples, the utility model can provide a plastic grinding cylinder for each sample, thereby avoiding cross contamination and the samples can be recycled after being cleaned. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0013] As attached Figure 1 , 2 As shown, the utility model provides a replaceable drum soil grinder, including a reduction motor 14, a motor reduction box 1 is arranged at the rear end of the reduction motor 14, the rear end of the motor reduction box 1 is connected to a connecting shaft 10 through a coupling 5, the connecting shaft 10 transversely penetrates the bearing seat 6, and extends to the inside of the grinding cylinder 7 to be connected to the grinding blade 13, the part of the connecting shaft 10 located inside the grinding cylinder 7 is provided with a hexagonal nut 11, the rear end of the grinding cylinder 7 is provided with a rear cover 8, and the upper part of the rear cover 8 is connected to the silo 9.
[0014] Specifically, the motor reduction box 1 is installed on the motor mounting frame 2 , and the motor mounting frame 2 is arranged on the pad 3 .
