Description

one

The invention relates to mechanical engineering for fodder production, in particular to the pressing of hay-straw materials.

Known balers, which contain mounted on a frame with wheels, a pressing chamber with a piston and in the hinge apparatus, a receiving chamber with packers mechanisms, having a forks mounted on the crankshaft at the side loading window of the press chamber. For the drive, an asterisk is installed at the end of the shaft, connected by a chain loop and cardan gear with a common drive of the machine lj.

The disadvantage of this baler is that the specified drive of packers cannot be used in presses that form large bales, i.e. in the new direction of feed procurement, which allows mechanization of lifting and transport operations, significantly reduce labor costs, as well as reduce the consumption of composite material. Balers for receiving large bales have a large bale chamber, and therefore the loading device for feeding material into the bale chamber has significant consumption due to the design of the crankshaft and its drive, the length of which should be equal to the width of the bale chamber.

The closest to the invention to the technical essence is a trailed baler comprising a frame mounted on wheels on which a press chamber with a piston and in a hinge apparatus is placed, a pick-up and a receiving chamber with a loading device made in the form of a forked comb, with a crankshaft mounted a shaft having a drive link kinematically associated with the vehicle's PTO, which is located in the longitudinal axis of symmetry of the baler 2j.

A disadvantage of the design is the location of the drive link at the end of the crankshaft, which necessitates the installation of a bulky and complex drive for transmitting torque from the PTO shaft.

tractor to the drive link boot device.

The aim of the invention is to reduce metal consumption and reduce 5 dimensions.

The goal is achieved by the fact that the trailed baler, which includes a frame mounted on wheels, on which a bale chamber with a piston and in a hinge apparatus is placed, a pick-up and a receiving chamber with a loading device, made in the form of a forked comb, mounted on a crankshaft

the shaft having a drive link, kinematically connected with the vehicle's PTO, which is located in the zone of the longitudinal axis of symmetry of the baler, the drive link

located in the middle of the crankshaft on its neck and in the zone of the longitudinal axis of symmetry of the baler.

FIG. 1 shows a trailed baler, side view, section view; on

FIG. 2 - the same, top view, section.

Trailed baler includes a frame 1 mounted on wheels 2, pick 3, press 3, the bale chamber 4 with a piston 5 and a back wall 6,

on which a pressure sensor 7 is mounted in a filling apparatus 8 of a receiving chamber 9 with a charging device 10 (in Fig. 2) consisting of forked dies 11 mounted on a crankshaft 12, a drive link 13 and a ton g 14.

The drive link 13 is located along the axis of the baler and receives rotation from the tractor's PTO through a bevel gearbox 15 and transmission: cardan 16, belt 17 and chain 18. The baler works as follows.

When driving across a field, an aggregate consisting of a baler and

the tractor, the pick-up 3 lifts the material from the floor and feeds it into the receiving chamber 9, from where the forks 11 of the loading device 10 are fed. The material is fed into the pressing chamber 4, where it is pressed into the bale by the piston 5. Upon reaching the specified bale density, the sensor 7 mounted on the rear wall 6, sends a signal for inclusion into the digger 8. After the bale is twisted with a twine, the rear wall 6 is opened and the finished bale is pushed out

from the bale chamber 4 to the incoming material.

The use of the invention will reduce the maximum range 877534

dragging torque in the most loaded section of the crankshaft, which in turn leads to a simplified design and reduced material consumption of the 5 loading device.
