Experiment and Study of Garlic Root Cutting Based on Continuous Force Feedback

Abstract

In this study, we quantified and analyzed the root-cutting process of garlic with a test bench with pressure sensors on the basis of the comparative analysis of various information perception methods. On the basis of the output value of the pressure sensor, the force curve of garlic roots was plotted, and the double round blade cutting module is optimized on the basis of the force curve diagram. The innovative proposal of slotted round blades for garlic root cutting is presented here. The round blade diameter is 110 mm, the center distance is 100 mm, the blade thickness is 1 mm, and the blade speed is 1200 r/min. According to the analysis of the force curve, it was found that the slotted round blade with the slanted blade could generate a strong thrust to cut the roots. The cutting effect was better and the cutting surface of the roots was straight. The slotted blade meets the need for cutting garlic roots.

Theory of Movement of the Sugar Beet Tops in Loading Mechanism, Taking into Account the Influence of the Air Flow

“…When analyzing Expression (15), it can be argued that at the moment the particle enters the thrower blade and at the initial stage of the particle movement along the blade, while its relative velocity .…”

“…x will decrease, which means that, according to (15), force F nx will also decrease; that is, the influence of the airflow will weaken.…”

“…It should be noted that one of the main elements of the theory of movement of the cut tops of sugar beet when it is loaded into a vehicle after being cut by a haulm harvester is the theory of the movement of a piece of tops along the blade of a centrifugal thrower, which receives the tops after being cut by the cutting device. Despite the fact that the theory of the movement of a material particle along the working surfaces of agricultural machines has been created with sufficient completeness, first of all, thanks to the fundamental works of Vasilenko P.M. [9], in connection with the development of new types of working bodies of agricultural machines in recent years [10][11][12][13][14][15][16], this theory needs to be changed and clarified, which is connected not only with the design features of these working bodies but also with bringing the rather cumbersome form of the formulated equations to a closed form, which will be convenient to use in further modeling and practical calculations on a PC. This particularly applies to the development of a new theory of the movement of a particle of the cut beet tops along the blade of the thrower of the loading mechanism of the topping machine.…”

Theoretical Study of the Motion of a Cut Sugar Beet Tops Particle along the Inner Surface of the Conveying and Unloading System of a Topping Machine

“…The issues related to the motion and sliding of particle M along the surface of the working parts of agricultural machines are partly considered in works [33][34][35][36], but no attention is paid to the influence of the external environment in which the particle is moving.…”

Design and Testing of a Clamping Manipulator for Removing Abnormal Plants in Rape Breeding

“…Zhang et al [12] designed a single-row cabbage harvester with two symmetrical disctype cutting knives to cut cabbage roots and determined suitable working parameters to ensure the stability of root cutting. Yang et al [13] found that slotted circular blades with beveled edges cut garlic roots better and optimized the double circular blade cutting module by experiment. Hou et al [14] designed a disc-type castor cutting device and optimized the tool parameters using simulation tests.…”
