Description
Technical field
The utility model relates to the pick-up unit of a kind of soil compaction and humidity, and this device is applicable to the outdoor Site Detection to soil compaction and humidity, belongs to soil function detection field.
Background technology
Due to the operation of walking in field of the farm implements of tractor and traction thereof, tire rolls effect to soil, cause topsoil to be depressed heavy, the degree of packing increases, especially in recent years, extensive along with various agricultural equipments, frequent use, this compaction also increases thereupon, well beyond the natural restoring force to soil compression, soil compression phenomenon is on the rise, and owing to using a large amount of chemical industry fertilizer to cause the degree of packing that hardens of soil to increase, soil compression is lost the aperture between soil particle, cause that air and water can not free flows, and then affect development condition and the crop yield of root system of plant, cause crop failure, therefore, learn that soil packing degree seems particularly important.
Conventionally adopt in the world cone index CI (Cone Index) to characterize soil cultivation layer depth and tillage resistance, concentrated expression soil by machines physical property, mostly adopt sand replacement method both at home and abroad, tradition core cutter method, the indirect methods such as drop hammer type measuring method, measure soil packing degree, it is low that these methods are not only measured efficiency, and accuracy of measurement is not high, domestic original adoption is from spot sampling, then in the indoor method of testing, these methods adopt manual method by circular cone injection soil mostly, the record of data adopts range estimation reading more, only single for compactness in test process, do not consider the humidity of soil.
Summary of the invention
The purpose of this utility model is to provide the pick-up unit of a kind of soil compaction and humidity, comprise humidity sensor 1, bracing frame 2, pressure transducer 3, electric pushrod 4, scrambler 5, single-chip microcomputer 6, LCDs 7, detect box 8 and reference test bar 9, electric pushrod 4 is arranged on bracing frame 2, scrambler 5 and reference test bar 9 are arranged on electric pushrod 4, humidity sensor 1 and pressure transducer 3 are arranged on reference test bar 9, single-chip microcomputer 6 and LCDs 7 are integrated into and detect in box 8, and are connected with scrambler 5, humidity sensor 1 and pressure transducer 3 by circuit.
Single-chip microcomputer 6 described in the utility model is STC89C52 model single-chip microcomputer.
The utility model in use, this device is placed on to soil surface to be tested, utilize bracing frame 2 that equipment is fixed, by single-chip microcomputer 6 human-computer interaction interfaces, set the degree of depth and the length of reference test bar 9 retention time in soil of wanting testing soil, start this device, utilize single-chip microcomputer 6 to control electric pushrod 4 push to test bars 9, vertical is pressed in soil to be measured, in this process, by the electronic scrambler 5 pushing away on 4, record the number of turns of motor rotation, obtain the displacement of electric pushrod 4, determine the degree of depth of reference test bar 9 injection soil, by P1.4 mouth, data are sent to single-chip microcomputer 6, with default value contrast, when the degree of depth of injection reaches after preset value, monolithic 6 is controlled electric pushrod 4, electric pushrod 4 is no longer moved downward and keep 1 ~ 3min, by pressure sensing 3, measure this deep soil force value, by P1.0 oral instructions in single-chip microcomputer 6, through single-chip microcomputer 6, process and obtain soil packing degree value, the humidity value of measuring this deep soil by humidity sensor 1, by P1.3 oral instructions, in single-chip microcomputer 6, then single-chip microcomputer 6 is presented in LCDs by P0 port and by these data, and test finishes.
The beneficial effects of the utility model are: equipment is simple and practical, are convenient to realize robotization and control, and test data is convenient to watch and is read, and is convenient to test soil packing degree and the humidity of different depth.
