Problems solved by technology

In the actual experiment process, the soil samples are usually placed on the ground to dry, which takes a lot of time, and the samples exposed to the air are easily polluted, and it is also difficult to dry the soil samples evenly.
In the determination of soil fertility and enzyme activity, different types of indicators need to pass through sieves with different apertures, and generally need to be repeatedly ground, the grinding efficiency is low, waste of manpower, and affect the subsequent test data of the experiment.
[0003] Existing sample grinding devices for geotechnical engineering have complex structures, troublesome maintenance, and poor grinding effects. Therefore, the present invention provides an air-drying and grinding integrated device for soil samples to solve the problems in the above-mentioned background technology. proposed question

Embodiment 1

[0031] Such as Figure 1~Figure 3 Among them, an air-drying and grinding integrated device and method for soil samples, including a grinding box 1 and a screening box 2, the upper side of the grinding box 1 is connected with a hopper 3, and a grinding mechanism is arranged in the grinding box 1, and the grinding box 1 The lower side of the screen is communicated with the upper side of the screening box 2, and the grinding box 1 can be dismantled. The two sides of the bottom of the screening box 2 are respectively fixedly connected with two vertically symmetrical brackets 4, and the two brackets 4 are far away from the screening box 2. One end of the screen is fixedly connected with an annular base 5, and the screening box 2 is detachably and fixedly connected with an inclined screen 6, and one side of the screening box 2 is fixedly connected with a vibration motor 7, and the bottom of the screening box 2 is connected with a discharge port. 8. The ground samples fall into the s...

Embodiment 2

[0041] Such as Figure 4 , an air-drying and grinding integrated device and method for soil samples, different from the first embodiment: the grinding box 1 is removed, the threaded outlet 8 is removed and replaced with a hot air blower 22, the soil sample Place on the sieve 6, turn on the hot air blower 22, the temperature of the hot air is 60 degrees Celsius, and the wind speed is 5m / s, and then the soil sample in the screening box 2 can be air-dried and ground. The structure is simple, the grinding is stable, and the maintenance is easy. convenient.

[0042] Because the thermal air flow density is small, the water vapor of the soil sample is discharged from the top by the hot air from bottom to top, and the soil sample will be evenly air-dried. After the power is turned off, the sieve 6 is removed and taken out.

Abstract

The invention discloses an air drying and grinding integrated device for a soil sample and a method. Fertility and soil enzyme activity can be measured after the soil sample is treated by the device, the upper side of a grinding box communicates with a hopper, a grinding mechanism is arranged in the grinding box, the lower side of the grinding box communicates with the upper side of a screening box, the two sides of the bottom of the screening box are fixedly connected with two supports which are vertically and symmetrically arranged correspondingly, and the ends, away from the screening box, of the two supports are fixedly connected with an annular base. According to the device and the method, a hot-air blower mechanism is arranged to carry out rapid hot-air drying on the sample so as to save a lot of time, the grinding mechanism is used for grinding, the structure is simple, grinding is stable, a screen and a vibration motor are arranged to screen and process the sample, the grinding quality is improved, a material returning mechanism is arranged to facilitate backflow of the screened sample to the hopper for repeated grinding, grinding efficiency is improved, manpower is saved, and material waste is avoided.

Description

technical field [0001] The invention belongs to the field of basic agricultural technology, and relates to an air-drying and grinding integrated device and method for soil samples. Background technique [0002] Soil provides the necessary nutrients for plant growth. The study of soil fertility and soil enzyme activity is an indispensable part of the field of basic agricultural science. The measurement of soil sample nutrients is mainly divided into four steps: soil extraction, air drying, grinding, and analysis. In the actual experiment process, the soil samples are usually placed on the ground to air-dry, which takes a lot of time, and the samples are easily polluted when exposed to the air, and it is also difficult to air-dry the soil samples evenly. In the determination of soil fertility and enzyme activity, different types of indicators need to pass through sieves with different apertures, and generally need to be repeatedly ground, the grinding efficiency is low, waste ...
