he use of vibration transport in agricultural production plays a very significant part. Vibratory conveyors have the variety of advantages over traditional transporting ma-chines such as auger and belt type conveyors used at agri-cultural enterprises for transporting mainly loose and granular materials. A rather low wear coefficient of trans-porting body itself - a conveying trough of a vibration-transporting machine may be referred to the advantages, besides, in some constructions of vibration-transporting machines the amount of friction couples is reduced to a minimum.

Abstract Currently, loosening and separating machines that combine the operations of crumbling and separating of soil according to the treated layer depth have come to the forefront. Interaction of the rotor blade of these machines with the soil comprises three stages: soil core formation; steady movement; and dumping of soil from the separating grid. The article determined the direction and magnitude of soil displacement, parameters and shape of the furrow formed after the ripper passage.

In the article, theoretical studies of the disturbed motion of oscillation of the carrier system of the gantry machine on pneumatic wheels are carried out. Mathematical models of load formation on the frame of the load-bearing system of the lifting and transporting machine in the longitudinal and transverse vertical planes are presented. Equations of natural frequencies of the system have been obtained, which allow to determine at the stage of designing the elements of the supporting systems of gantry machines the operating modes of the machine in the pre-resonance or post-resonance zone.

Abstract:

In conventional mechanized cut-to-length systems, a harvester fells and cuts trees into logs that are stored on the ground until a forwarder picks them up and carries them to landing sites. A proposed improvement is to place logs directly into the load spaces of transporting machines as they are cut. Such integrated loading could result in cost reductions, shorter lead times from stump to landing, and lower fuel consumption. However, it might also create waiting times for the machines involved, whereas multifunctional machines are likely to be expensive. Thus, it is important to analyze whethe

Most lifting and transporting and loading and unloading machines have a hydraulic drive. One of the most common actuators that perform reciprocating and rotary movements are hydraulic cylinders, characterised by one-sided wear of the rod seals. Known rod assemblies are elastic sleeves mounted in the hydraulic cylinder housing, which covers the rod with a guaranteed gap. During the unit operation, a gap seal forms in the gap between the rod and the sleeve, which prevents the leakage of the working fluid from the high-pressure cavity and centres the rod in the sleeve.

Abstract:

The article discusses ways to reduce energy consumption in the open-pit mining of minerals in the conditions of Kuzbass by reducing the sticking to the working automobile equipment and excavator complexes. When excavating and transporting cohesive rocks, due to a sharp change in climatic conditions, adhesion-cryogenic processes occur (sticking, freezing on excavator buckets, dumpcars, conveyor belts, dump truck bodies, etc.). This significantly reduces the efficiency of excavating and transport complexes. In this paper, we consider the adhesion-cryogenic processes affecting the rock, methods o

Abstract:

Mathematical modeling with the original approach is used to study the dynamics of low-frequency electro-vibration machines while taking the technological load into account. Based on the mathematical analysis of differential equations describing the oscillatory motion of electromagnetic vibration exciters, the existing mathematical model has been corrected to describe the action of a semiconductor diode in the power circuits of single-cycle vibrators. Modeling nonlinear dynamic systems reveals the difficulties of obtaining the amplitude-frequency characteristics of the associated discrete chang

Abstract:

The application of solid organic fertilizer is primarily a manual process, leading to inefficiencies and substantial labor demands. The complexity of the task, combined with the market’s lack of machinery capable of both loading and spreading, presents significant challenges. This study introduced the design of an integrated machine that facilitates the loading, transporting, and spreading of solid organic fertilizer. Utilizing the discrete element method, we simulated these processes to refine the machine’s efficiency. EDEM software was used for simulation calculation. The goal was to identif

Abstract:

This paper studies a new automated container terminal (ACT) system which utilizes multistory frame bridges and rail-mounted trolleys to transport containers between the quay and the yard. Beside typical ACT systems use trucks or automated guided vehicles for transporting containers between quay cranes and yard cranes, the new design uses three types of handling machines, namely, ground trolleys (GTs), transfer platforms (TPs), and frame trolleys (FTs). These three types of handling machines collaborate with one another to transport containers. This study decomposes the system into several subs

Haymaking processes are applied by natural (at the field) or artificial drying methods (in warehouses and special dryers). During drying, the hay may be loose or loosely baled. The machines that can be used in various stages of haymaking from harvesting forage to filling the warehouse can be listed as strimmers, crushers, windrow harvester

Cattle breeders in Bone district usually have a shortage of cattle feed in the form of grass and hay in the dry season. Usually grass or straw is not stored in a warehouse because of limited space. Cattle supply is adjusted when daily needs are not based on each month or year. Cattle farmers in Bone district still carry out the process of transporting grass or straw naturally so that the capacity of the feed being transported is small and requires a long time. To get 5-10 kg of cattle feed, it takes a day while the needs of cattle are 60-120 kg per day. To increase the productivity of breeders

In addition to the multi-rescue system, the cargo lifting mechanism also includes a winch. Winches with one drum, which have standard parameters - traction force from 3.2 to 125 KN at rope speed from 0.5 to 0.1 m/s, are most often used in PTM. Such winches include a two-stage gear reducer that connects the electric motor with the drum. Such a winch drive scheme is quite large and has considerable weight.

The efficiency of transport and production operations depends on the mutually agreed work of road transport, harvesting machines and functioning of reception points. The degree of adaptability to perform the functions assigned to them allows you to assess the efficiency of using road transport in transporting goods according to the “field-elevator” scheme. One of the criteria for assessing the efficiency of road transport is full energy cost per unit.
