The rotating body 4 is rotated, and the pull rod 51 realizes the tension measurement of the stems 10 at different angles.
Specifically, as shown in fig. 1 and fig. 2, fig. 1 is a schematic front view of the present invention. Fig. 2 is a schematic top view of the present invention.
In order to be able to measure the pressure of the external force on the stalks 10 more accurately, the pressure sensors 12 are embedded in the placing part 11 so that the stalks 10 can directly abut against the pressure sensors 12. The tilt angle sensor 13 may be mounted to the horizontal upper surface of the first clamping part 1 so that the tilt angle sensor 13 may be used to measure the angle at which the stalks are tilted with respect to the vertical direction. The side of the block 21 close to the stalk 10 is a vertical surface, and the block 21 can move according to the outer diameter of the stalk 10, so that the distance between the block 21 and the first clamping part 1 is the outer diameter of the stalk 10. The emitting point of the infrared emitting piece 14 is in the same vertical plane with the position where the stalk 10 is stopped against the placing part 11. And then through handheld tray 3, rotate first clamping part 1 and second clamping part 2, can measure the external diameter size of stem stalk 10 through infrared transmitter 14.

The swivel 4 can be rotated in the vertical direction, so that the pull rod 51 can adjust the angular position in the vertical direction. The swivel 4 is partially embedded in the second grip 2 so that the pull rod 51 can apply a pulling force to the second grip 2, the first grip 1 and the stem 10 through the swivel 4. And can measure the pressure born by the stalks through the pressure sensor 12 while exerting the pulling force on the stalks 10.
One end of the rotating body 4 is embedded into the second clamping portion 2, and the other end of the rotating body 4 extends out of the second clamping portion 2 and is connected with one end of the pull rod 51 through a bolt. The other end of the pull rod 51 is connected to the measuring box 5.
The tension sensor 51 is used to measure the tension applied by the stalks 10 from vertical to the outer skin break. The tension angle sensor 53 is used to measure the angle of the tension with respect to the horizontal.
By the implementation of the invention, the first clamping part 1 and the second clamping part 2 are connected with each other, so that both sides of the stalk 10 are respectively stopped against the placing part 11 and the baffle 21. Since the baffle 21 can move in the second clamping part 2, so that the tray 3 is held by hand, the first clamping part 1 and the second clamping part 2 are rotated, the distance between the baffle 21 and the placing part 11 changes along with the size of the outer diameter of the stalk 10, and the distance between the baffle 21 and the placing part 11, namely the outer diameter of the stalk 10, is measured through the infrared emitter 14. The pull rod 51 is connected with the rotating body 4, the rotating body 4 is rotated for an angle through the pull rod 51, tension is applied to the stems 10 through the pull rod 51, and relevant numerical values are respectively measured by the inclination angle sensor 13, the tension sensor 52 and the tension angle sensor 53. Because the swivel 4 can freely rotate on the vertical plane, the stem 10 can be pulled from different angles on the vertical plane, and different numerical values can be collected. And then can be through the setting of first clamping part 1, second clamping part 2, tray 3, swivel 4 and measurement box 5, can measure the external diameter size of stem stalk 10 and exert pulling force to stem stalk 10 at arbitrary angle on the perpendicular. Can overlap through first clamping part 1 and second clamping part 2 and establish stem stalk 10 to through handheld measuring box 5 to stem stalk 10 realize the tensile force measurement of the arbitrary angle of perpendicular, thereby can simplify measuring equipment, be convenient for measure rice stem stalk lodging resistance intensity in the field.
As an alternative embodiment, a thrust rod 22 for pressing or puncturing the stalk 10 is further included. Pushing rod 22 includes pushing rod 221 and puncturing rod 222. The thorn rod 222 is inserted and extended out of the outer side of the push rod 221 and is connected with the push rod 221 by screw thread. The push rod 221 movably penetrates the stopper 21 and extends out of the second clamping portion 2. One end of the push rod 221 or the barbed rod 222 abuts against the stem 10.
Specifically, as shown in fig. 1 and 2, by the arrangement of the pricking pin 22, it is possible to apply pressing and pricking to the stalk 10, so that the pricking pressure and the crushing pressure of the stalk 10 can be measured by the pressure sensor 12.
The pricking pin 222 extends outside the pushing rod 221, that is, the stem side of the pricking pin 222 is located inside the pushing rod 221, and the side of the pricking pin 222 away from the stem extends outside the pushing rod 221. Therefore, when the stalk 10 needs to be punctured, the puncturing rod 222 is convenient to rotate from the outer side of the push rod 221, so that the stalk side of the puncturing rod 222 extends out of the inner side of the push rod 221, and the stalk side of the puncturing rod 222 is prevented from abutting against the stalk 10. The outer side of the push rod 221 and the outer side of the first clamping part 1 are simultaneously pressurized, so that the stalk 10 is punctured, and the pressure value of the stalk 10 during puncturing is measured through the pressure sensor 12. In the process of puncturing, the pressure value is gradually increased, and the pressure value is reduced when the puncturing rod 222 punctures the stem 10, wherein the maximum pressure value is the puncturing pressure value of the stem 10.
Similarly, barbed rod 222 is located inside of push rod 221, the inside of push rod 221 resting against stem 10. The extrusion of the stalks 10 is realized by applying pressure to the outer side of the push rod 221 and the outer side of the first clamping part 1 at the same time, and the pressure value of the stalks 10 during extrusion is measured by the pressure sensor 12. In the implementation process of the extrusion, the pressure value is gradually increased, and the pressure value is reduced when the push rod 221 crushes the stalks 10, wherein the maximum pressure value is the crushing pressure value of the stalks 10.
Further, the push rod 221 includes a first push rod 2211 and a second push rod 2212. One end of the first push rod 2211 forms an arc-shaped surface and is stopped against the stem 10. The other end of the first push rod 2211 is connected to one end of the second push rod 2212, and the other end of the second push rod 2212 forms a wavy surface adapted to fingers and extends out of the second clamping portion 2. The other end of the bayonet 222 protrudes from the second push rod 2212.
Specifically, as shown in fig. 1 and 2, the first push rod 2211 and the second push rod 2212 may be integrally formed for convenience of manufacturing. In order to more stably stop the first push rod 2211 against the stem 10 during extrusion, an end of the first push rod 2211, i.e. a stem side end of the first push rod 2211, is formed as an arc-shaped surface. The other end of the second push rod 2212, that is, the end surface for pushing by hand, is formed into a wave shape matched with fingers, so that the fingers can be conveniently placed when the hand is held, and force can be conveniently applied when the hand is squeezed and punctured. The central axis of the bayonet 222 may coincide with the central axes of the second push rod 2212 and the first push rod 2211.
As an alternative embodiment, the stop surface of the placing part 11 and the stalk 10 is formed as an arc surface. The stopping positions of the arc-shaped surface and the stem 10 and the emitting surface of the infrared emitting part 14 are the same plane.
Specifically, as shown in fig. 2, in order to make the stalks 10 firmly abut against the placing part 11, the placing part 11 and the abutting surface, i.e., the contact surface of the stalks 10 form an arc surface. In order to enable the infrared emitting component 14 to accurately measure the outer diameter of the stem 10, the stopping position of the arc-shaped surface and the stem 10, namely the contact position when the arc-shaped surface and the stem are stopped and the emitting surface of the infrared emitting component 14, namely the plane where the emitting point of the infrared emitting component 14 emitting infrared rays is located, is the same plane.
As an alternative embodiment, a first sliding groove 23 for moving the stopper 21 is formed in the second clamping portion 2. The stopper 21 is connected to a side wall of the first slide groove 23 in the moving direction of the stopper 21 by an elastic member 24.
Specifically, as shown in fig. 2, the elastic member 24 may be a spring. The first sliding groove 23 may be opened in the second clamping portion 2 in a horizontal direction. The stop block 21 is positioned in the first sliding groove 23, one end of the stop block 21 is stopped against the stem 10, and the other end of the stop block 21 is connected with one end of the elastic element 24. The other end of the elastic member 24 is connected to the inner wall of the first sliding groove 23.
When in use, the first clamping part 1 and the stopper 21 clamp the stem 10, and the elastic element 24 pushes the stopper 21 to stop against the stem 10. Because the outer diameter of the rice straw is oval, when the outer diameter of the straw 10 is larger in the rotating process of the first clamping part 1 and the second clamping part 2, the outer wall of the straw 10 generates thrust on the stop block 21, so that the stop block 21 slides outwards in the first sliding groove 23; when the outer diameter of the stalk 10 is small, the elastic part 24 generates thrust to the stopper 21, so that the stopper 21 slides inwards in the first sliding groove 23, and the stopper 21 always abuts against the outer wall of the stalk 10.
As an alternative embodiment, a plurality of sliders 31 are slidably attached to the tray 3. The upper ends of the plurality of sliders 31 are detachably inserted into the bottom portions of the first and second clamping portions 1 and 2.
Specifically, as shown in fig. 1, the tray 3 includes a first tray and a second tray, one end of the first tray and one end of the second tray are rotatably connected by a pin, and the other ends of the first tray and the second tray are inserted into each other and then threaded-connected by a bolt passing through the overlapped insertion portion. The first and second trays are interconnected around the stalk 10.
A circular second chute 32 is formed in the tray 3. The lower ends of a plurality of sliders 31 (only one is shown in the figure) are embedded into the second sliding grooves 32 to slide, the upper ends of the plurality of sliders 31 can be inserted into the bottoms of the first clamping portion 1 and the second clamping portion 2 in a clamping manner, and the sliders 31 can be separated from the bottoms of the first clamping portion 1 and the second clamping portion 2 only by applying external force. A plurality of slider grooves corresponding to the plurality of sliders 31 are respectively formed at the bottoms of the first clamping portion 1 and the second clamping portion 2. The upper end of the sliding block 31 can be movably inserted into the sliding block groove, namely the sliding block 31 can be freely inserted into or separated from the sliding block groove, the tray 3 is held by hands, the sliding block 31 can be separated from the sliding block groove when upward force is not applied to the tray 3, and the disassembly is convenient.
As an alternative embodiment, a plurality of hemispherical bumps for limiting the rotation of the rotator 4 are uniformly distributed on the outer surface of the vertical circumference of the rotator 4.
Specifically, as shown in fig. 1 and fig. 2, the rotating body 4 may be a sphere, and in order to increase the rotation range of the rotating body 4, the protruding blocks are disposed on the outer surface of the vertical circumference passing through the center of the sphere, and the protruding blocks are movably embedded in the inner wall of the second clamping portion 2. The rotating body 4 can also be a cylinder, and the central axis of the cylinder is horizontally arranged. The cylinder and the inner wall of the second clamping part 2 can be rotationally connected through a rotating shaft. The outer surface of the vertical circumference of the cylinder is evenly provided with convex blocks which are movably embedded into the inner wall of the second clamping part 2.
