Fig. 3 is objective table schematic diagram of the present invention;
In figure: base 1, left double pulley 2, objective table 3, right double pulley 4, guide rail 5, scale 6, screw rod 7, slide block 8, stepper motor 9, pulling force sensor 10, screwed hook 11, belt 12, balling class vegetables 13.
Embodiment
Below in conjunction with accompanying drawing and example, the invention will be further described.
As shown in Figure 1 and Figure 2, a measurement mechanism for the balling class vegetables degree of packing, comprises base 1, left double pulley 2, objective table 3, right double pulley 4, guide rail 5, scale 6, screw rod 7, slide block 8, stepper motor 9, pulling force sensor 10, screwed hook 11, belt 12, balling class vegetables 13:
Left double pulley 2, objective table 3, right double pulley 4 are installed on plateau on the left of base 1 successively; Guide rail 5, scale 6 are installed on the right side of base 1, and scale 6 is used to indicate the position of slide block 8; Screw rod 7 is installed on guide rail 5, and slide block 8 and screw rod 7 form screw thread pair, and be installed on the slideway of guide rail 5, slide block 8 can do rectilinear motion along the slideway of guide rail 5; Stepper motor 9 is installed on guide rail 5 right-hand member, and stepper motor 9 output shaft is connected with screw rod 7, drives screw rod 7 to rotate; Pulling force sensor 10 is fixed on slide block 8, does rectilinear motion with slide block 8; Screwed hook 11 is threaded connection on pulling force sensor 10, for hooking belt 12 two ends; Belt 12 walks around right double pulley 4, balling class vegetables 13 surface, left double pulley 2 successively, and belt 12 two ends are all equipped with circular hole, and the circular hole at two ends is all connected with screwed hook 11 hook end.
As shown in Figure 2, left double pulley 2 and the double pulley in the right side 4 are double pulley, and the method that belt 12 is wound around double pulley is left double pulley 2 end cross winding, the unidirectional winding of right double pulley 4 end, and this winding method makes balling class vegetables 13 uniform force; Selected belt 12 is rigidity belt, does not produce elastic stretching.
As shown in Figure 3, objective table 3 upper end of the present invention has a circular groove, is convenient to place balling class vegetables 13, and lower end has a rectangular through-hole, is convenient to belt 12 and passes through.
The course of work of the present invention is as follows:
(1) initialization: stepper motor 9 drives slide block 8, and rectilinear motion is to original state left, and pulling force sensor 10 registration resets;
(2) put into sample: balling class vegetables 13 are positioned over objective table 3 circular groove place, be positioned under belt 12;
