Description

The device relates to means of quality control of the technological process of agricultural machines and can be used to determine grain losses allowed by combine harvesters in the harvesting process.

A well-known controlled device for collecting grain losses allowed by combine harvesters for harvesting according to patent No. 171483, IPC A01D 75/00, 2016, which is installed and fixed in the bakery before the work (passage) of the combine and is intended for separate collection of grain losses behind the header and behind the threshing and separating device (LSG).

The known device according to patent No. 171483, IPC A01D 75/00, 2016 contains a cylindrical plastic case with two rectangular windows cut in it on top of the same length, insulated from each other in the middle of a cylindrical fixed plastic partition and individually overlapped by a movable spherical cover, the lateral ribs of which are interfaced with the side stops-limiters, on which it can be moved on grooves cut out at the sides from one sampling window to another. To exclude the displacement of the device in the barn, it is fixed with semicircular metal pins (lugs) by pressing them into the soil. The second compartment is opened by means of a cord, by means of which the locking pin of the movable spherical cover is pulled out.

The disadvantages of the known device are as follows:

the proposed diameter of the device in combination with irregularities in the relief of the field does not protect the combine cutting apparatus from contact with the device and breakdowns,

the cord used to activate the device must have a considerable length, since, according to the standard, the operator (agronomist) is forbidden to be closer than 10 meters from the working combine and the minimum cord length must be appropriate,

It’s very difficult to properly lay the device’s activation cord among the stands Improper laying of the cord can result in it being wrapped around the reel of the combine or falling into the cutting machine. This threatens not only to stop the combine and damage the sampling device, but also to injure the device operator (agronomist), because he must hold the cord in his hands before activation,

lugs fix the device from above, and this increases the overall height of the device relative to the field surface, which can bring to the contact of the cutting machine of the combine with the device and breakdowns,

lugs are a separate removable element. If they are lost, the device cannot be fixed on the field, and therefore used.

The technical task of the utility model is to ensure the safety of the device operator (agronomist), eliminating breakdowns of the cutting apparatus of the combine and the device for collecting grain losses.

The technical problem is achieved in that the device containing the housing, separated by a partition, a spring, a trigger with a locking pin and lugs, according to a utility model, is equipped with a remote wireless control system for the locking pin, the body is made in the form of half a cylindrical plastic pipe, the cover is flat, and lugs are fixed under the housing in its lower part.

The invention is illustrated by drawings.

In FIG. 1 shows a side view of a device for separately collecting grain losses behind the components of a combine harvester, FIG. 2 view A (from the end).

The proposed device for collecting grain losses contains a housing 1, in which two receiving zones are formed from each other using a plastic partition 2 in the middle part and plastic plugs 3 and 4 from the edges. A flat cover 5 is placed on the housing 1, mounted with the ability to move along the housing 1. The length of the cover 5 is at least not less than the length of one receiving zone. With the help of the bracket 6, a spring 7 is fixed on the inside of the cover 5 from the inside. On the other hand, the spring 7 passes through the groove cut out at the top of the plastic partition 2 and is attached by the bracket 8 to the plastic plug 3. The side ribs of the cover 5 are equipped with longitudinal grooves and are interfaced with the sidewalls the housing 1 through the pins 9 installed in it. Support pins 10 are mounted on the pins 9 so that the lid 5 moves freely. The cover 5 with a stretched spring 7 is held by an actuator with a locking pin 11. An actuator with a locking pin 11 and a remote control are included in the wireless remote control system of the locking pin. The actuator 11 is mounted on the cover 5 so that, in working condition, the locking pin passes into the hole in the cover 5, the joint hole in the housing 1 and fixes the cover 5 in this position. Grousers 12, mounted at the edges, fix the device on the soil surface. Lugs 12 can be made folding using loops 13 for easy transportation of the device.

The technological process of collecting grain losses by the proposed device for the combine harvester is as follows.

Before the passage of the combine, the device is installed in the row-spacing of the grain stand outside the wheel track and fixed along the edges with lugs 12 by pressing them into the ground.

To bring the device into working condition, the cover 5 is transferred to the extreme position opposite to the plug 3, stretching the spring 7. The cover 5 is fixed by means of an actuator with a fixing pin 11, combining the holes in the cover 5 and the housing 1.

When the combine passes over the installed sampler, grain losses from the header fall (wake up) into its open receiving zone. After the header has been passed, the actuator with the locking pin 11 is activated using the remote control. The pin comes out of the hole in the housing 1 and the cover 5, under the action of the spring 7, moves to the side of the plug 3, opening another receiving area for receiving losses for the ISU.

After the harvester passes from the receiving areas of the sampler, the losses are sequentially extracted into different containers, cleaned, weighed, and the amount (%) of grain losses behind the header and LSG is determined for subsequent comparison with acceptable loss values.
