Soil grinding system

Abstract

The invention discloses a soil grinding system. Two extrusion plates are symmetrically installed on the two sides in a grinding tank through spring assemblies. A motor is installed in a movable cover. The rotating shaft end of the motor is connected with a grinding assembly through a fourth electric telescopic rod. The grinding assembly comprises a transverse plate. The transverse plate is connected with a first grinding rod through a first electric telescopic rod set. First grinding rods are connected with second grinding rods through a second electric telescopic rod set. The second grinding rods are connected with third grinding rods through a third electric telescopic rod set. The lower bottom faces of third grinding rods are fixedly connected with a grinding plate. Movable baffles are installed at the two ends of the transverse plate through rotating shafts with power devices. The first grinding rods, the second grinding rods and the third grinding rods are each provided with grinding particles and brush layers alternately. The soil grinding system is simple in structure, reasonable in design and easy and convenient to operate, manpower and material resources are saved, the processing efficiency is improved, harm caused by dust to health of workers and pollution caused by the dust to the environment are reduced, practicability is high, and the soil grinding system is easy to use and popularize.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a soil grinding system. Background technique [0002] For soil grinding equipment, such as the United States and Canada, the soil samples collected from the field are ground with a stainless steel pulverizer, which is fast and time-saving. The average hourly grinding of soil samples is 5 times that of manual labor. The volumetric method is used for sampling through a 2mm aperture sieve. There are three sample spoons of 1g, 5g, and 15g; Germany and other European countries use a four-bowl grinder for grinding, grinding 4 soil samples each time, and then change the grinding body for the next grinding, and clean the replaced bowl. Carry out the next reincarnation; while my country's soil testing and formula fertilization standards require soil samples to be ground by hand, soil and fertilizer stations or agricultural stations at all levels that implement soil testing and formula fertilization...

[0002] For soil grinding equipment, such as the United States and Canada, the soil samples collected from the field are ground with a stainless steel pulverizer, which is fast and time-saving. The average hourly grinding of soil samples is 5 times that of manual labor. The volumetric method is used for sampling through a 2mm aperture sieve. There are three sample spoons of 1g, 5g, and 15g; Germany and other European countries use a four-bowl grinder for grinding, grinding 4 soil samples each time, and then change the grinding body for the next grinding, and clean the replaced bowl. Carry out the next reincarnation; while my country's soil testing and formula fertilization standards require soil samples to be ground by hand, soil and fertilizer stations or agricultural stations at all levels that implement soil testing and formula fertilization work have a large amount of soil samples, and most of the soil samples are ground by themselves from the market. Pulverizer purchased online for pulverization. The pulverizer models are complex and varied, which will affect the accuracy and accuracy of the test and reduce the scientificity and authority of soil testing and formula fertilization.

[0003] Since the Ministry of Agriculture organized the implementation of soil testing and formula fertilization in 2005, a total of 15.63 million soil samples and 1.25 million plant samples have been collected across the country, and 98.13 million tests of macroelements, medium and trace elements and other indicators have been completed. The testing work, especially the grinding treatment of soil samples in the early stage, requires a lot of manpower and material support. The dust generated by manual hand rolling of soil samples affects the health of the staff, pollutes the surrounding environment, and easily leads to low efficiency of soil grinding
