Description

Manual soil grinder

Technical Field

The invention relates to the technical field of soil grinding, in particular to a manual soil grinding device.

Background

Soil is the material basis for sustainable development of the economic society, and mineral nutrition required for growth of crops is mostly derived from soil. In modern agriculture, the application of chemical fertilizers plays an important role in improving crop yield and ensuring grain safety, and the applied chemical fertilizers are transformed and integrated in soil so as to be supplied to plants for growth. The effective soil fertilization management can effectively improve the soil fertility, further improve the grain yield and regulate and control the crop quality; however, improper fertilization can reduce agricultural productivity and even lead to soil degradation and other serious environmental problems. On the other hand, the unreasonable development and utilization of land in production and life causes soil pollution, and then directly threatens the grain safety and sustainable development. Therefore, soil nutrient management based on agrochemical analysis is of paramount importance in modern agricultural production.

The soil needs to be ground and sieved before it can be tested. At present, the soil is ground by a manual mode and a grinding grinder mode, wherein the manual mode mainly comprises modes of hammer striking and crushing, wood roller rolling and the like, and the method is time-consuming, labor-consuming, low in efficiency, and high in difficulty in grinding soil samples with fine grain sizes due to low hardness and poor wear resistance of wood tools; the automatic grinding instrument or the pulverizer is used for grinding the soil, so that equipment investment can be greatly increased, and when a large number of different soil samples are processed, the difficulty of cleaning equipment is high to prevent cross contamination, and large sample loss or loss can be caused, so that analysis accuracy is affected. In research and production, the number of soil samples is large, and efficient and convenient soil grinding treatment technology is needed.

FIG. 1 is a schematic view of a grinding apparatus of the present invention;

FIG. 2 is a schematic view showing the structure of a grinder in the grinding device according to the present invention;

in the figure: 1. the grinding machine comprises a first baffle plate, a second baffle plate, a liner, a base, a grinder, a guide groove, a shaft and a bearing.

Detailed Description

The following description of the present invention will be made more complete and clear in view of the detailed description of the invention, which is to be taken in conjunction with the accompanying drawings that illustrate only some, but not all, of the embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

As shown in fig. 1 and 2, a manual soil grinding device includes: the base 4, enclose and keep off frame and grinder 5, wherein base 4 is the arc structure of indent, encloses and keep off frame shape and base 4 assorted, encloses and keep off the frame and constitute by first baffle 1 and with second baffle 2, first baffle 1 and with second baffle 2 head and the end interval connection form the structure of encircleing base 4. The grinder 5 is arranged in the enclosure frame, the grinder 5 is of a spindle type structure, stainless steel bearings are arranged at two ends of the grinder 5, a second baffle 2 of the enclosure frame is fixed with the base 4 through a hinge, and a supporting column for supporting the base 4 is arranged at the bottom of the base 4.

Preferably, a liner 3 is paved on the base 4, kraft paper is adopted for the liner 3, the first baffle plate 1 and the second baffle plate 2 of the surrounding baffle frame are pressed on the liner 3, and are attached to the liner 3 after suddenly grinding is required, so that the liner is convenient to move and take, and meanwhile, cross infection caused to the next analysis process can be avoided.

As shown in fig. 2, two first baffle plates 1 of the enclosure frame are provided with guide grooves 6, shafts 7 are movably arranged in the guide grooves 6, stainless steel bearing inner rings at two ends of the grinder 5 and the shafts 7 are fixedly arranged in the enclosure frame, and the grinder 5 can reciprocate between the base 4 and the enclosure frame through manual pushing, so that the purpose of grinding soil is achieved. Meanwhile, when the surrounding baffle frame is lifted, the grinder 5 can be supported, the grinder 5 can be clamped in the guide groove 6, the liner 3 can be conveniently pulled out from the side, a soil sample can be collected, and the grinder 5 can be fixed.
