Abstract
The invention discloses facility greenhouse photophobic crop stem and fruit size laser measuring equipment, and relates to the technical field of plant growth state detection. The facility greenhouse photophobic crop stem and fruit size laser measuring equipment is provided with a base plate on which a level gauge is installed. A stand column is vertically fixed at one end of the base plate. A measuring ruler is vertically fixed at the other side of the base plate symmetrically. A slide slot is vertically arranged along the center of the stand column. The slide slot is internally provided with a rolling shaft which slides along the slide slot. The rolling shaft is provided with a laser device. The numerical value of the bottom end of the measuring ruler is low, and the numerical value of the upper end is high. mm acts as the minimum unit of the measuring ruler. Embedded inverted numerical scales are evenly arranged in each cm. A concave slot corresponding to the end part of the laser device is arranged for each scale. Plant stem diameter can be rapidly measured without damaging the plant so that the structure is simple and measuring accuracy is high.
Description
Technical field
The present invention relates to plant growth state detection technique field, specifically a kind of facility plastic greenhouse keeps in dark place crops stem
Stalk, fruit size laser measuring equipment.
Background technology
Agricultural production needs the measure such as growing state control irrigation, fertilising, the prevention and control of plant diseases, pest control according to plant.By agricultural producer's eye-observation, judge the upgrowth situation of plant with the experience of the producer, the data obtained can vary with each individual, accuracy declines, and the excessive use moisture of meeting and fertilizer, cause unnecessary waste or pollution, serious also can affect crop yield.Multiple sensors is adopted to carry out the upgrowth situation of perception plant in modern agriculture, because plant growth situation is difficult to directly measure, but the situation of monitoring plant growth is carried out by indirectly measuring other indexs that can characterize these changes, wherein plant haulm diameter is exactly an important indicator of the upgrowth situation of a very important sign plant.
At present vernier caliper, contact Linear displacement transducer and computer visual image treatment technology are mainly contained to the device of the diameter measurement of plant haulm.In three, the precision of vernier caliper measurement is higher, but needs to compress plant haulm by vernier caliper when measuring, and has certain damage to plant; Need during contact line style displacement sensor to apply a suitable pretightning force to plant, the existence of this pretightning force affects the normal growth of plant; Computer visual image treatment technology high cost, and measurement result precision is lower.In view of above reason, be necessary to provide a kind of measuring accuracy higher, especially to the novel plant stem stalk diameter sensor measurement mechanism of plant haulm diameter nondestructive measurement.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the invention provides facility plastic greenhouse and to keep in dark place crops stem stalk, fruit size laser measuring equipment, when not damaging plant, measuring plant haulm diameter fast and accurately.
The present invention realizes with following technical scheme: facility plastic greenhouse keeps in dark place crops stem stalk, fruit size laser measuring equipment, comprises base plate, base plate is provided with level meter; A column is vertically fixed in one end of base plate, and the opposite side symmetry of base plate vertically fixes a dip stick; Center vertical along column arranges a chute, and in chute, installation one is along the roller bearing of slide, roller bearing is installed a laser instrument; The bottom numerical value of dip stick is little, and upper end numerical value is large, and dip stick take mm as least unit, is evenly provided with embedded inverted digital scale in each cm, and the end that each scale corresponds to laser instrument is provided with the groove of indent.
The invention has the beneficial effects as follows: when not damaging plant, Quick Measuring measures plant haulm diameter; Structure is simple, and measuring accuracy is high.

Fig. 2 is dip stick scale schematic diagram;
Fig. 3 is pillar construction schematic diagram.
In figure: 1, chute, 2, switch, 3, column, 4, laser instrument, 41, laser head, 5, battery case, 6, roller bearing, 7, dip stick, 8, stem stalk to be measured, 9, base plate, 10, level meter.
Embodiment
as shown in Figure 1,keep in dark place crops stem stalk, fruit size laser measuring equipment of facility plastic greenhouse has a base plate 9, base plate 9 is provided with level meter 10; A column 3 is vertically fixed in one end of base plate 9, and the other end symmetry of base plate 9 vertically fixes a dip stick 7; Center vertical along column 3 arranges a chute 1, and in chute 1, installation one is along the roller bearing 6 of slide, roller bearing 6 is installed a laser instrument 4; The battery case 5 of laser instrument 4 is provided with switch 2, controls opening or closing of laser instrument by switch 2.
Base plate 9 adopts the base plate that can regulate length, by the length of regulating base board, makes it meet stem stalk to be measured, realizes accurately measuring fast.
As shown in Figure 2, the bottom numerical value of dip stick 7 is little, and upper end numerical value is large, and dip stick take mm as least unit, is evenly provided with embedded inverted digital scale in each cm, and the end that each scale corresponds to laser instrument is provided with the groove 11 of indent.Wherein, inverted digital is from-9 ~-1, and the numerical value of bottom is from 0.
As shown in Figure 3, laser instrument 4 is arranged in the chute of column 3 by roller bearing 6, and the center, front end of laser instrument 4 is laser head 41, and laser injects to dip stick from laser head, carries out Measurement accuracy to the diameter of plant haulm.
The course of work: 3 joint button cells are loaded battery case, opens switch 2 and generating laser 4 is worked.As shown in Figure 1, be stuck in measurement mechanism by stem stalk 5 to be measured, ensure that level meter 10 balances, plant haulm is fitted measurement mechanism completely, and now laser instrument 4 is positioned at position A, and embedded inverted digital scale is injected without any laser.Keep measurement mechanism level, plumbness constant, slip roller bearing to embedded inverted digital scale has laser to inject gently, and laser is injected and is a little plant haulm diameter, and now laser instrument 4 is positioned at position B.
The each scale in the embedded inversion size scale left side has a groove, and be convenient to laser vertical when injecting certain size, embedded inverted digital scale can obviously read concrete size, is more conducive to reading the number of degrees in the undesirable situation of illumination.The scale of embedded inverted digital scale adopts unique " subtraction " design, deducts the little number of degrees obtain concrete test value according to the large number of degrees.Such as, the position of "-2 " below laser testing scale " 9 ", represents, 9-0.2=8.8cm.
