Adjustable straw pull-out force measurement device

Abstract

The invention discloses an adjustable cotton straw pull-out force measurement device which comprises a rack base (16), a reducer motor (9), guide rails (14) that are arranged on the rack base (16), awinding wheel (11) arranged on an output shaft of the reducer motor (9), self-locking slide blocks (13) arranged on the guide rails (14), a rack (8) arranged on the self-locking slide block (13), a pulley support frame (7) arranged on the rack (8), a V-shaped pulley (6) arranged on the pulley support frame, a pull-out rod (4), a steel wire rope (5) connected with the pull-out rod (4) and the winding wheel (11), a tension sensor (3) arranged between the pull-out rod (4) and a pull-out clamping mechanism (2), a data acquisition card (17) connected with a signal output end of the tension sensor (3), and a pull-out knife (1) arranged on the pull-out clamping mechanism (2). The rack base (16) is fixed with worm support seats (12) via lock nuts (15), and the reducer motor (9) is fixed on the rack base (16) via a motor support seat (10). The device has the advantages that the device is relatively simple in structure, and good in outdoors adaptability and can effectively reduce labor intensityof manual measurement, and collected data can provide a reference for a design of a pull-out device of a cotton straw harvesting machine.

Description

technical field [0001] The invention relates to the technical field of measuring the mechanical properties of cotton straw roots, in particular to an adjustable cotton straw pulling force measuring device. Background technique [0002] Cotton is a very important field economic crop in my country, and the cotton stalk left in the field after harvest is an important biomass resource. Cotton stalks can not only be used as field fertilizer to improve soil aggregate structure, realize the combination of land use and nutrition, and promote production increase, but also can be used as culture material for edible fungi, high-grade feed for animal husbandry, and raw materials for industrial products such as papermaking, high-density fiberboard, and sound insulation board. Making full use of cotton stalk resources and improving the comprehensive utilization effect of cotton stalks has good development prospects and economic benefits. At present, most of the cotton stalks in my countr...

Problems solved by technology

At present, the domestic measurement of cotton stalk pulling force is mostly manual stalk pulling measurement, but manual stalk pulling measurement is not only time-consuming, labor-intensive, and inefficient, but also unstable in force application and large in error in measured data
