Abstract

Provided are a device and method for measuring corn ear threshing force of bare hands. The device comprises a torque measurement instrument, a rack and a torque sensor, the signal output end of the torque sensor is connected with the torque measurement instrument, and a flexible clamp used for fixing a corn ear sample is arranged at one end of the torque sensor. The measurement method comprises the steps that the corn ear sample is divided into a plurality of equal-length regions to be measured in the axial direction of the corn ear sample, one end of the sample is clamped in the flexible clamp, a scaleplate is adjusted to be aligned at the starting threshing position of the nth region to be measured, the suspension end of the corn ear sample is manually rotated for threshing, when the suspension end of the corn ear sample is rotated to the finial position from the starting threshing position, a final trigger is triggered at the same time, the torque of the current position is displayed through the torque measurement instrument, and the threshing force of the nth region to be measured at different threshing moments can be obtained through data processing. According to the device, the threshing force borne by corn ears is measured in the bare hand threshing process, and theoretical foundations are provided for parameter setting of the threshing device.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a device and method for measuring the threshing force of corn ears with bare hands. Background technique [0002] Most of the existing combine harvesters directly harvest corn cobs, and then perform threshing through corn threshers. Corn threshers are one of the main agricultural machinery products, and their performance directly affects the efficiency and quality of corn threshing. When threshing corn ears, the loss rate of existing threshers is relatively high and the loss is relatively large. Damage is one of the main forms of corn quality reduction. Damaged corn is prone to breakage during transportation, moisture absorption, mildew, and pests and diseases during storage, which affects the grade, precision and germination rate of seeds after processing. Threshing damage in mechanized harvesting is an important factor for damage to corn and other grains, which directly a...
