Description

The invention relates to agricultural machinery, in particular to machines for harvesting and grinding feed, as well as harvesting and threshing grain and cereal crops.

The purpose of the invention is to improve the reliability and durability of the machine by automatically removing foreign metal objects from the flow of plant mass.

Figure 1 shows the machine for cleaning the feed in the initial position, in the absence of plant mass of a foreign metallic object in the flow of the plant, its overall appearance; Fig. 2 shows a machine for harvesting feed after detecting a foreign metallic object in the vegetable mass, general, i.e.

The machine for cleaning the feed consists of a replaceable adapter made in the form of a picker mechanism 1 with a feed conveyor 2 and a screw 3 with a case 4, feed 5 and crushing 6 apparatus, as well as a device for detecting and removing foreign metallic objects. W, it is from the sensor 7 of the metal detector, an additional sensor 8 of the metal detector, the electronic unit 9 and the valve 10 with the drive.

The feed harvesting machine works in the following way.

The vegetable mass from the roll by the pick-up mechanism 1 and the feeding conveyor 2 is fed to the screw 3, which narrows the weight and feeds it into the feeding apparatus 5 and further to the grinding apparatus 6. At the same time, the damper 10 is in the lower position, being an extension of the shield 4 of the screw. 3

When grabbing together with the mass of a metal object, an additional sensor 8 of the metal detector sends a signal to the electronic unit 9, which turns on the actuator (not shown) of the shutter 10 and moves the shutter to the upper position, preventing access of vegetative mass to the supply unit 5. At the bottom of the casing 4 a window is formed for the free release of the plant mass and the foreign metallic object from the machine. When a metal object passes through the formed window, the detector 7 of the metal detector sends a signal to the electronic unit 9, which switches the valve 10 actuator, which takes it to the lower position, opening up the vegetative mass to the feeding unit 5.

For a better separation of the crop flow, the working edges of the shutter 10 are sharpened.
