Problems solved by technology

Therefore, it is necessary to determine the best threshing force of the threshing device, the best threshing position on the sunflower disc and the angle between the sunflower disc and the center line of the sunflower disc, etc. These data can provide a theoretical basis for future threshing devices, but now Some devices are insufficient for this purpose

Embodiment Construction

[0027] The present invention will be further elaborated below in combination with specific embodiments.

[0028] As shown in the figure: a sunflower plate clamping device for impact testing machine, the device is equipped with a main shaft 5, an upper circular plate 14, a lower circular plate 12, a lower splint 15, a connecting plate 18, an upper splint 20, a ring Shaft 21, support rod 10, connection plate 9, cross bar 11 and scale 6, described upper circular plate 14 is fixedly arranged on the top of main shaft 5, described lower circular plate 12, cross bar 11 and connection plate 9 are along the top to The direction of the bottom end is fixedly sleeved on the main shaft 5 in turn, the ring shaft 21 is sandwiched between the upper circular plate 14 and the lower circular plate 12, there are 6 lower splints 15, and the 6 lower splints 15 can be spliced It forms a ring shape with a central hole. The lower splint 15 is composed of a fan-shaped plate I1501 and a rotating end 150...

Abstract

The invention relates to a sunflower disc clamping device for an impact test machine, and a method for measuring an impact force. The device is provided with a main shaft, an upper circular plate, a lower circular plate, a lower clamping plate, a connecting plate, an upper clamping plate, an annular shaft, a supporting rod, a connecting disc, a cross rod, and a dividing rule. The device measures the sizes of impact forces for impacting the seeds of sunflowers of different types at different positions and angles. The device can directly read a set angle, and the size of the impact force can be directly read from the impact test machine. The device is small in error, and can provide a scientific basis for the quantitative analysis of threshing damage of the sunflower seeds. A nut below a supporting rod connecting plate is manually adjusted to one angle of the dividing rule, and the upper clamping plate and the lower clamping plate form certain angles with the main shaft. The nut is screwed up to clamp a sunflower disc, thereby enabling the sunflower disc to be shaped like a cone at a certain angle. The values of the dividing rule are the angles corresponding to the inclination angles of the upper and lower clamping plates in a one-to-one manner.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a sunflower disk clamping device used in an impact testing machine and a method for measuring impact force. Background technique [0002] At present, my country's sunflower planting area is relatively large, mainly distributed in Inner Mongolia, Shaanxi, Shanxi and other places. The current sunflower detachment in my country has not yet fully realized mechanized operations, and most of them still rely on manual threshing. Most of the detachment principles of existing sunflower threshers It is the impact type, and most of them are detached after the sunflower plate is dried and the seeds are loosened. After threshing, the grain damage rate of this machine is high. Because the sunflower plate is broken, the impurity rate of the grain is high, which brings more trouble to the cleaning work. big trouble. Damage is one of the main forms of quality reduction of sunflower seeds. Dam...
