Abstract
The invention provides a device for detecting bending resistance of rice stalk and belongs to an agricultural scientific research instrument. A T-shaped groove is formed in a base, a fixed support plate is fixedly arranged at the side part of the upper end face of the base to form a cantilever-shaped structure, a T-shaped positioning pin and a T-shaped bolt are mounted inside the T-shaped groove, an adjustable support plate is fixedly arranged on the T-shaped positioning pin, the T-shaped bolt is inserted in the hole of the adjustable support plate, the adjustable support plate is fixed on the upper end face of the base by the engagement of the T-shaped bolt and a locking nut and has a cantilever-shaped structure, and a fixed limiting plate and an adjustable limiting plate are fixedly arranged on the fixed support plate and the adjustable support plate respectively. The inner side face of the fixed support plate and the inner side face of the fixed limiting plate are staggered as well as the inner side face of the adjustable support plate and the inner side face of the adjustable limiting plate are staggered, resulting in a step-shaped integral structure. Fine sand is loaded into a heavy matter drum with a hanger. The device has the advantages of simple structure, low manufacturing cost, convenience for adjustment and operation, high detection accuracy and wide application range.
Description
Technical field
The invention belongs to the agri-scientific research instrument, relate generally to a kind of Culm of Rice fracture resistence force determinator.
Background technology
The Culm of Rice fracture resistence force is to instigate Culm of Rice or the internode used power that fractures, the size of its fracture resistence force affects the lodging tolerance of paddy rice Culm of Rice in growth course, final decision paddy rice yield per unit area, so science determines that accurately the Culm of Rice fracture resistence force is the important content of paddy rice research work.But, because the defective on the structural design, existing Culm of Rice fracture resistence force determining instrument exist accuracy of measurement poor, can not truly reflect the technical matters such as Culm of Rice fracture resistence force and detected Culm of Rice length dimension be strict and single.
Summary of the invention
Purpose of the present invention is exactly the problem that exists for above-mentioned prior art, actual needs in conjunction with agri-scientific research and production operation, design provides a kind of Culm of Rice fracture resistence force determinator of new construction, reaches to increase substantially to measure precision, purpose applied widely.
The object of the present invention is achieved like this: T-shaped groove laterally is set on the base upper surface; Fixed support plate is being packed on the sidepiece of base upper surface of cantilever design; But T-shaped register pin and T-shaped screw are installed in transverse shifting ground in T-shaped groove, be fixedly mounted with the adjusting back up pad at T-shaped register pin upper lateral part, T-shaped screw inserting is in regulating the support plate hole, set nut screws on T-shaped screw, to regulate back up pad by T-shaped screw and cooperating of set nut and be fixed on the base upper surface, and be cantilever-shaped structure; On fixed support plate and adjusting back up pad upper side, be fixedly mounted with respectively fixedly limiting plate and adjusting limiting plate, described fixed support plate medial surface and fixedly between the limiting plate medial surface and regulate the back up pad medial surface and all being dislocation between the limiting plate medial surface and configuring with regulating, it is step-like that integral body is; Equipped fine sand so far consists of Culm of Rice fracture resistence force determinator in the weight bucket of suspension hook.
The present invention adopts and to be cantilever design at base and to be fixedly mounted with respectively with the fixed support plate of fixing limiting plate and to be equipped with movably adjusting back up pad with the adjusting limiting plate, thereby can adjust flexibly according to the Culm of Rice panel length, satisfy and the excessive or too small mensuration needs of adaptation culm length; In the weight bucket, annotate the dress fine sand, make the mensuration of its Culm of Rice fracture resistence force more accurate, improved the detection quality, have characteristics simple in structure, cheap for manufacturing cost, that the adjusting use is easy to operate, accuracy of detection is high, applied widely, for high yielding culture of rice aspect resistant to lodging research provides technical support.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present invention is described in detail.A kind of Culm of Rice fracture resistence force determinator laterally arranges T-shaped groove 12 on base 1 upper surface; Fixed support plate 2 is being packed on the base 1 upper surface sidepiece of cantilever design; But T-shaped register pin 13 and T-shaped screw 7 are installed in transverse shifting ground in T-shaped groove 12, be fixedly mounted with adjusting back up pad 5 at T-shaped register pin 13 upper lateral parts, T-shaped screw 7 insertings are in regulating back up pad 5 holes, set nut 8 screws on T-shaped screw 7, to regulate back up pad 5 by T-shaped screw 7 and cooperating of set nut 8 and be fixed on base 1 upper surface, and be cantilever-shaped structure; On fixed support plate 2 and adjusting back up pad 5 upper sides, be fixedly mounted with respectively fixedly limiting plate 3 and adjusting limiting plate 6, described fixed support plate 2 medial surfaces and fixedly between limiting plate 3 medial surfaces and regulate back up pad 5 medial surfaces and all being dislocation between limiting plate 6 medial surfaces and configuring with regulating, it is step-like that integral body is; At the weight bucket 9 interior equipped fine sands 10 with suspension hook 11.
When operation is used, the support of tested Culm of Rice 4 both ends is placed on fixed support plate 2 and regulates on the back up pad 5, according to the distance between the definite fixedly limiting plate 3 of the length of Culm of Rice 4 and the adjusting limiting plate 5, namely unclamp set nut 8, on base 1, regulate back up pad 5 along T-shaped groove 12 transverse shiftings, under Culm of Rice 4 natural extended length, make its both ends respectively with fixing limiting plate 3 medial surfaces with regulate limiting plate 6 medial surfaces and contact, tightening set nut 8 makes adjusting back up pad 5 fixing at base 1, utilize suspension hook 11 that weight bucket 9 is hung on Culm of Rice 4 centre positions, then slowly evenly be injected into fine sand 10 in the weight bucket 9, when Culm of Rice 4 fractures, take by weighing the general assembly (TW) of weight bucket 9 and fine sand 10, namely get the fracture resistence force data of this Culm of Rice 4.
