RU226700U1 - QUICK-REMOVABLE JUICE DRAIN BOARD FROM UNDER THE FORAGE HARVESTER RECHOPPER Chopper - Google Patents

Abstract

The utility model relates to the field of agricultural engineering, namely, forage harvesters, which include a shield under the grain grinder, which removes the juice released during operation and provides access to the mechanisms located under the frame of the combine. The purpose of the utility model is to expand the functionality, improve the consumer qualities and ease of use of the shield under the additional chopper during the operation of the combine. To achieve the specified technical result, a quick-release shield located under the grain regrinder of a forage harvester, which is a flat-shaped part made of sheet steel, with holes, is made entirely of sheet steel, with an inclined part for draining juice beyond the mechanisms installed under the shield, The shield is fastened to the frame on one side by a screw connection at two points, and on the other hand by a tongue-and-groove type fastening, where the groove is on the shield and the tenon is on the frame. Due to the use of tongue-and-groove fastening, the number of fastening screw connections is reduced and, accordingly, the dismantling of the shield is accelerated. For ease of dismantling, there is a hole in the shield that you can grab with your hand and remove the shield. The technical result consists in removing the juice released during operation from the additional chopper along the slope by gravity outside the combine mechanisms, facilitating and speeding up the procedure for dismantling the shield.

Description

The utility model relates to the field of agricultural engineering, namely, forage harvesters, which include a shield under the grain grinder, which removes the juice released during operation and provides access to the mechanisms located under the frame of the combine.

Known forage harvesters from the companies “Claas”, “New Holland”, “Krone”, “John Deer” [1. The new 8000 series self-propelled Forage Harvesters. -John Deer Prospectus. Website www.JohnDeer.com. 2. Built for the job. Self-propelled Forage Harvesters. - John Deer Company Prospectus. Website www.deere.com. 3. New Holland FR9000 series Forage Harvesters. - New Holland Company Prospectus. Website www.new_Holland.com/na. 4. Krone. Big X forage harvester - Krone brochure. Website www.Krone.de], which are equipped with an opening shield for access to the combine engine maintenance, ensuring the operation of the organs that ensure the harvesting process and protecting the engine from pollution from the environment.

The closest to the claimed utility model is the Jaguar 980 forage harvester from Claas [Jaguar 980-930 Operating Manual, CLAAS. Website www.claas.com], in which the shield located under the grain grinder, which ensures the removal of juice released from the mown plants during operation of the combine, is made of flat sheet steel, has holes for the flow of juice from the grinder and is connected to the frame of the combine with a screw connection in four places.

The design of the prototype shield under the re-chopper of the John Deer 8300 forage harvester has the following disadvantages:

1) a large number of screw connections;

2) the inconvenience of unscrewing the bolts in the far part of the shield;

3) contamination of mechanisms located under the shield by plant juice.

The purpose of the utility model is to expand the functionality, improve the consumer qualities and ease of use of the shield located under the additional chopper during the operation of the combine.

To achieve the specified technical result, the quick-release shield located under the grain grinder of the forage harvester, which is a flat-shaped part made of sheet steel, with holes, is made of all-welded sheet steel,

- with an inclined part for draining juice beyond the mechanisms installed under the shield, the shield is fastened to the frame on one side by a screw connection at two points, and on the other hand by a “tenon-groove” type fastening, where the groove is on the shield and the tenon - on the frame. Due to the use of tongue-and-groove fastening, the number of fastening screw connections is reduced and, accordingly, the dismantling of the shield is accelerated. For ease of dismantling, there is a hole in the shield that you can grab with your hand and remove the shield.

The inventive device is illustrated by the drawings shown in Fig. 12:

- fig. 1 - quick-release shield for the juice drainage system from under the grinder (bottom view);

- fig. 2 - general view of the quick-release shield installed on the combine (right view).

The inventive quick-release shield includes the following structural elements (Fig. 1, 2): 1 - shield; 2 - screw connection; 3 - shield “groove” fastening; 4 - frame “spike” fastening; 5 - mounting hole; 6 - hole for ease of dismantling; 7 - combine frame.

The claimed utility model works as follows. To protect the mechanisms from contamination by juice during operation of the additional chopper, a shield 1 is installed and secured under it. When the additional chopper is operating, the secreted juice of mowed plants falls on the inclined part of the shield and moves by gravity to an area free from mechanisms to prevent their contamination. To access the mechanisms, it is necessary to dismantle the shield 1 by unscrewing two screw connections 2 from the frame 7, which are attached through the mounting holes 5, after which it is necessary to manually pull the shield toward you, grasping the hole 6, to release the fastening “groove” 3 from engagement with the “ spike" of frame 4, and remove shield 1. Installation is performed in reverse order.

The technical result consists in removing the juice released during operation from the additional chopper along the slope by gravity outside the combine mechanisms, in facilitating and speeding up the procedure for dismantling the shield.

Claims (1)

A quick-release shield for draining juice from under the re-chopper of a forage harvester, which is a flat-shaped part made of sheet steel with holes, characterized in that the shield is made entirely of sheet steel with an inclined part for draining juice beyond the mechanisms installed under the shield, while fastening the shield to the combine frame is made on one side in the form of a screw connection at two points, and on the other side - with a tongue-and-groove type fastening, with the groove located on the shield and the tenon on the combine frame.
