LOADER-GRINDER FOR GROSS FEED, including a suction cutter-drum mounted on the outer end of the rotary pneumatic pipe, at the opposite end of which there is a main fan with a discharge pipe, and an additional grinding body enclosed in the housing, the shaft of which is placed parallel to the center of the suction drum and main fan, characterized in that, in order to increase productivity and reliability in operation by ensuring consistent the speed of air flow and reduction of its aerodynamic resistance, an additional grinding working body is placed between the main fan and the discharge pipeline and equipped with additional fans installed on its both sides, on the same shaft with it in the casing, made in the upper part of the casing, and a discharge pipe, which narrows from the ends of the casing to the discharge pipe and communicates with it.

Description

BACKGROUND OF THE INVENTION The invention relates to loaders and pulp mills for coarse feed used in agricultural production.

A grinder loader for coarse feeds is known, which includes an intake working element mounted on the outer end of a rotary pneumatic pipeline, at the opposite end of which a fan with discharge pipe is installed, and a grinding working element fixed parallel to the axis of the intake working body and fan in the discharge pipeline one.

The disadvantage of this loader-grinder is the increased aerodynamic resistance due to the stirring of the grinding tool in the center of the discharge pipeline.

The closest to the technical drying of the invention is a heavy duty chopper loader, including a suction cutter-drum mounted on the outer end of a rotary pneumatic pipeline, at the opposite end of which there is a main fan with a discharge pipeline, and an additional grinding body, enclosed in a casing, which is located parallel to the axis of the intake cutter-drum and the main fan 2.

The disadvantage of this loader-grinder is that it does not provide a consistent build-up. Speed: airflow growth, as well as high aerodynamic resistance due to the installation of an additional chopping device before the main fan and its cutting elements flow. As a result, its performance and operational reliability are significantly reduced.

The purpose of the invention is to increase productivity and reliability in operation by providing a consistent increase in the speed of air flow and a decrease in its aerodynamic resistance.

This is achieved by the fact that an additional grinding tool is placed between the main fan and the discharge pipeline and is equipped with additional fans installed on its both sides on the shaft with it in the casing, a swirl chamber formed in the upper part of the casing, and a discharge pipe narrowing from the ends of the casing to the discharge pipe and communicated with him.

FIG. 1 shows a schematic representation of the proposed grinder loader for roughage, visited on a wheeled tractor, side view; in fig. 2 - the same loader grinder, visited on a tracked tractor, top view; in fig. 3 - unloading pipe additional grinding working body, a longitudinal section.

The loader-chopper for coarse feeds includes a suction cutter-drum 1 mounted on the outboard end of a vertical rotary pneumatic pipeline 2, at the opposite end of which there is a main fan 3 with a discharge pipe 4. Between the main fan and the discharge pipeline in the case 5 is located additional grinding working body, made in the form of a hammer rotor 6, the shaft 7 of which is placed parallel to the axis of the intake cutter-drum

0 and the main fan. On both sides of the hammer rotor, on one shaft with it, additional fans 8 are installed in one casing, equipped with partitions 9. On the inner surface of casing 5, deck 10 is fixed. In the upper part of the casing there is a vortex chamber 11, to which the discharge nipple 12 adjoins the ends of the casing to the discharge pipe 4 and communicated with him. At the end of the discharge pipeline fixed deflector 13.

When the loader-grinder is working, the rotating intake mill-drum 1 smoothly lowers onto the mow and separates the feed particles from it, partially crushing them. Pre-shredded

5, feed particles are supplied via a pneumatic conduit 2 to the main fan 3, which directs them to. final grinding to the hammer rotor 6. The latter, with its hammers, throws the crushed product into the discharge pipe 12,

0 where the additional fans 8 create an ejection of the air flow, ensuring its further transportation and ejection through the deflector 13 into the vehicle. The chamber 11 executed in the upper part of the housing

 contributes to the displacement of the center of the air flow, strengthening it at the exit of the vortex chamber.

Due to this implementation of the loader-grinder, a consistent increase in the speed of the air flow and a decrease in its aerodynamic resistance is achieved, which significantly improves its performance and reliability in operation.
