Description
Technical field
This utility model belongs to field of measuring technique, specifically, relates to a kind of crop stem bearing capacity determinator.
Background technology
Strategy on Super-high-yielding crops, particularly Rice Breeding for Super High Yield is on the basis of stable spike number, cultivates more
Big fringe.But the maximum fringe that Culm of Rice can carry weighs and maximum fringe is heavy and the stem rarely seen research of stalk correlation properties, and the most anti-fall
Volt research uses the cane method of fractureing to measure.Certain internode of choosing being artificial due to the stem stalk method of fractureing breaks, and
The fracture resistence force of each internode of Oryza sativa L. differs, it is impossible to when true measurement Oryza sativa L. grows naturally, own biological amount is held plus fringe portion maximum
The height that specifically fractures under loading capacity, more cannot measure the maximum fringe weight that stem stalk can carry.
Utility model content
In view of this, technical problem to be solved in the utility model is, prior art cannot be measured stem stalk and can carry
Maximum fringe weight problem.
In order to solve above-mentioned technical problem, the utility model discloses a kind of crop stem bearing capacity determinator, including:
Testing stand desktop, is provided with groove；For supporting the frame of described testing stand desktop, fix with described testing stand desktop and be connected；
Sleeve, is fixedly connected on described testing stand desktop and described frame, and is connected with described testing stand vertical；Protractor,
It is fixed on described testing stand desktop, and be arranged in parallel with described testing stand desktop；Slideway, is fixed on described testing stand desktop, and
It is arranged in parallel with described testing stand desktop；For clamping the gripping sleeve of crop stem, it is arranged at described sleeve inner；Protractor pushes away
Bar, fixes with described protractor and is connected.
Further, described crop stem bearing capacity determinator also includes tighting a bolt, with described sleeve and frame
Movable connection.
Further, described crop stem bearing capacity determinator also includes fixed pulley, is arranged in described groove.
Further, described crop stem bearing capacity determinator also includes minute surface, with described testing stand vertical
Connect.
Compared with prior art, this utility model can obtain and include techniques below effect:
1), crop fringe portion load capacity can be measured, and measure different cultivars maximum load capacity；
2) the concrete position that crop stem lodging fractures, is measured；
3), root can be fixed so that it is keep field nature growth conditions.
Certainly, implement arbitrary product of the present utility model must be not necessarily required to reach all the above technology effect simultaneously
Really.
Accompanying drawing explanation
Accompanying drawing described herein is used for providing being further appreciated by of the present utility model, constitutes one of the present utility model
Point, schematic description and description of the present utility model is used for explaining this utility model, is not intended that of the present utility model
Improper restriction.In the accompanying drawings:
Fig. 1 is crop stem bearing capacity determinator polycrystalline substance schematic diagram of the present utility model；
Fig. 2 is crop stem bearing capacity determinator Facad structure schematic diagram of the present utility model；
Fig. 3 is that this utility model crop stalk equivalent pulling force when being perpendicular to horizontal plane calculates schematic diagram；

Detailed description of the invention
Embodiment of the present utility model is described in detail, thereby to this utility model below in conjunction with drawings and Examples
How application technology means solve technical problem and reach the process that realizes of technology effect and can fully understand and implement according to this.
As depicted in figs. 1 and 2, crop stem bearing capacity determinator of the present utility model, including: testing stand desktop 103,
It is provided with groove；For supporting the frame 108 of described testing stand desktop 103, fix with described testing stand desktop 103 and be connected；Set
Cylinder 101, is fixedly connected on described testing stand desktop 103 and described frame 108, and vertical with described testing stand desktop 103 connects
Connect；Protractor 104, is fixed on described testing stand desktop 103, and be arranged in parallel with described testing stand desktop 103；Slideway 105, Gu
Due to described testing stand desktop 103, and it be arranged in parallel with described testing stand desktop 103；For clamping the gripping sleeve of crop stem
106, it is arranged at described sleeve 101 internal；Protractor push rod 107, fixes with described protractor 104 and is connected.
Further, also include tighting a bolt 102, with described sleeve 101 and frame 108 is movable is connected.
Further, also include fixed pulley 109, be arranged in described groove.
Further, also include minute surface 110, vertical with described testing stand desktop 103 be connected.
The Computing Principle of equivalence pulling force of the present utility model is as shown in Figures 3 and 4.
Detected the direction α of pulling force by the digital display strain gauge of built-in angular sensor, detect size F of pulling force simultaneously.Logical
Cross pulling force F and angle [alpha] and the pulling force measured in real time is corrected to the direction with horizontal plane, calculate equivalence pulling force F '.
Computing formula: F '=F × sin α, wherein α is direction of pull and horizontal angle.
The test philosophy of crop stem bearing capacity determinator of the present utility model is as follows:
During test, crop is put in sleeve 101, then regulates 102 closing sleeves 101 that tight a bolt, make crop fix.
Fixing crop fringe head with one end of pulling force rope (not shown), pulling force rope passes through fixed pulley 109, and fixed pulley 109 can move
Moving left and right adjusting position in groove, other end connects the digital display strain gauge (not shown) of built-in angular sensor,
The direction α carrying out power and pulling force measures.Exist additionally, be provided with protractor 104 on testing stand desktop 103 for measuring Culm of Rice
Corner under pulling force effect, the position of protractor 104 can regulate and regulate in the position of slideway 105.Crop stalk is by power
During stretch bending, owing to contacting with the protractor push rod 107 on protractor 104, so crop stem is in BENDING PROCESS, push away
Protractor push rod 107 on momentum hornwork 104 moves, and rotates how many angles, the bending of protractor push rod 107 such that it is able to read
Corner belongs to the most remaining relation with the corner of protractor 104.
This utility model uses pulling force rope one end to be connected with ear node, and opposite side is connected with digital display strain gauge, and digital display draws
Power meter built-in angular sensor.Can use digital display strain gauge with horizontal line intersect arbitrarily angled in make stem stalk fracture.
This utility model can obtain and include techniques below effect:
1), crop fringe portion load capacity can be measured, and measure different cultivars maximum load capacity；
2) the concrete position that crop stem lodging fractures, is measured；
3), root can be fixed so that it is keep field nature growth conditions.
Also, it should be noted term " includes ", " comprising " or its any other variant are intended to nonexcludability
Comprise, so that include that the commodity of a series of key element or system not only include those key elements, but also include the most clearly
