Description

FIG. 1, the thresher is shown in side view, and in FIG. 2- in the plan. ,

The chain thresher consists of a stannya 1, in which on the horizontal shaft b, with a sponge or a handle 7, on a pulley, there is a hair shaft 2, consisting of two flywheels connected by nlavkamn 10 and rods S; On the early buttressions, with gaps, implanted nlankas (whips) 3, of various lengths are mounted. Rotation of the scourge on the rods 8 on the one hand is limited by the ilkanamn 10, which can be resetted by the brackets supporting them closer or longer from the axis of rotation of the scourge, thereby changing the angle of incidence and, therefore, the force of striking the scourge, and on the other side of the scourge are supported by carving 9, fixed with one ends or on the wheel rim, or on fixed sleeves on axles 8 (Fig. 2), and serving to limit the reverse rotation of the scourge 3 after hitting the sheaves and for setting the scourges

in the working position by pressing in all the way into the slats 10.

Wired wheels 2 with scourges 3, on bed 1, full width of wheel 2, space 4, swivel about hinge 12 n supported in a backwards-fold position with a spiral spring 13, which causes the platform to be rubbed when struck by bnches but sheaves laid out on site 4.

For the direction of movement of the scourges, when hitting them on the ground, as well as to eliminate the possibility of NLP sheaves falling under the drum 2, on the platform 4, in the front part of it are reinforced in the intervals between the midrange of the scourges, curved hinges 14 with upper ends bent back.

The threshing sheaves are fed to the threshing machine on table 11, separated from the floor 1, by a kosvyazoshennym shield 15, through which the threshed material goes down to the impact platform 4.

When the wheel 2 rotates, the pests hit the material being laid out.

on the platform 4, the impact force is bent upwards, the passage past the edge of the squareBP 4 and the ventures are getting into the working position, being pressed by the springs 9 B and the bar 10.

Credmet {patent.

1. Chain thresher, characterized with the use of springs O, designed to limit the reverse rotation of the scourge 3 after hitting the latter on the sheaf and for returning them to their original working position as far as the stop on the bar 10,

fastened in the rim of the flywheel-a 2 and made with adjustable for the purpose of changing the angle of inclination of the beach in relation to the sheaf (Fig. 1).

2. With the use of the thresher indicated in paragraph 1 of the rotary about the hinge 12 p supported by the spring 13 of the inclined platform 4, with the aim of maintaining the threshed grain mass, in order to eliminate the ingress of which under the drum serve curvilinear fingers 14 fixed on the platform at intervals for free passage of the scourges (Fig. 1).
