Abstract

The utility model relates to agricultural engineering, namely to conveyor transport and conveyors, and is intended for loading bales of hay and straw materials in conjunction with balers or with a tractor of various modifications. The technical result is the creation of a universal trailed device for loading bales of hay. straw materials when aggregating it behind any baler or tractor. The technical result is achieved by the design features of the claimed invention, made constructively in the form of a solid frame on a wheel pair, on which two three-row chain conveyors (horizontal and inclined) are mounted, by sequential work ensuring the movement of bales from baler into the body of a vehicle. The device provides a one-time loading of bales made by balers on any vehicles.

Description

The utility model relates to agricultural engineering, namely to conveyor transport and conveyors, and is intended for mechanized loading of bales of hay and straw materials in conjunction with balers or tractors of various modifications.

Various conveyors for moving bales are known (TT-4 and others). The disadvantage of these conveyors is that they are stationary and their throwing devices are unregulated, and also that they are not designed to pick up bales directly from the field.

Known analogs in technical essence close to the claimed useful model of the device for loading bales, mounted on balers, firms "Klever", "Tikap" and JSC "Bobruiskagromash". The disadvantage of these devices is the very principle of moving the bales, which consists in sequentially pushing the bale out of the bale along the guides, which quickly become clogged and fail when the bales accumulate.

The closest in technical essence to the claimed utility model is (RF patent No. 2484614, 2013) "Trailed device for loading bales." The disadvantage of this invention can be considered that it can only work in conjunction with a baler.

The technical result is the creation of a universal trailed device for mechanized picking and loading of bales of hay and straw materials when aggregated behind any baler or with a tractor.

The technical result is achieved by the design features of the claimed invention.

A trailed device for mechanized loading of bales (Fig. 1) is made structurally in the form of a solid frame on a wheel pair 13, on which two three-row chain conveyors are mounted (horizontal 1, which is located at a height of 35 cm relative to the inclined conveyor 2, and the inclined conveyor is located on thrust bearing (thrust bearing) 15), by sequential operation ensuring the movement of bales from the baler or picking up bales by a horizontal conveyor from the field and moving into the body of the vehicle. The drive of the chain working bodies (drive chains 3, 4) of both conveyors is provided from the wheel, in which the sprocket 16 is mounted on the wheel hub 8, located on the shaft of the wheel pair of the device, which is connected by a chain drive 9 with a single-stage bevel gearbox 14 and the drive shaft of the horizontal drive chain conveyor. Rotation from a horizontal to an inclined conveyor is also transmitted through a chain transmission using sprockets installed coaxially with the sprockets of the drive chains.

On the drive chains of the conveyors, rails-plates 5 are installed, which are attached to brackets attached to the chain links. This ensures, in general, reliable movement of the bale, including preventing the possibility of slipping it off the inclined conveyor.

Changing the angle of elevation of inclined and horizontal conveyors is carried out by hydraulic cylinders 10, controlled from the cab by a motorist, in the range from 0 ° to 45 °, while providing mechanized pick-up, lifting and dumping of bales into the body of the vehicle.

The design of the inventive device for mechanized loading of bales is illustrated by the following drawings in Fig. 1:

a) top view;

b) front view.

Loading bales using the claimed utility model can be done in two ways. 1. In conjunction with the baler: the bale exiting the bale chamber of the baler goes onto a horizontal conveyor, which carries it to the base of the inclined conveyor. 2. Mechanized method: the selection of bales by the device is carried out directly from the field without a baler directly aggregated with a tractor (type MTZ-80, T-40, YuMZ-6) without using a power take-off shaft (PTO), thanks to a horizontal conveyor adjustable in height, which is equipped with special tines for picking up bales from the field.

The claimed utility model in both methods is aggregated through a telescopic adjustable hitch 7, which allows, if necessary, to lengthen or shorten the length of the hitch.

Both horizontal and inclined conveyors are sheathed from below and from the sides with a protective cover 11. The upper parts of both conveyors are fenced with side guides 12, which prevent the bale from falling off the conveyor.

The force of the weight of the inclined conveyor and the weight of the bales ascending along it create a tipping moment relative to the pivot point of the inclined conveyor. To compensate for this moment, the loader has counterweights, which are placed on a special platform 6 located on the opposite side of the inclined conveyor.

When transporting this device, it is provided that the operation of the drive chains of both conveyors is disabled.

Claims (2)

1. Trailed device for mechanized loading of bales, containing horizontal and inclined chain conveyors mounted on a wheel pair, characterized in that the horizontal conveyor is adjustable in height by means of a hydraulic cylinder remotely controlled from the tractor cab and is equipped with teeth for picking up bales from the field. 2. The device according to claim 1, characterized in that the conveyors are driven through a chain drive from a wheel, in the hub of which an asterisk is mounted.
