Description

The claimed utility model relates to the field of agricultural engineering, namely, to forage harvesters, which include a removable shield for access to the maintenance of the combine engine and protection of the engine from pollution from the environment.

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.newholland.com/na. 4. Krone. Big X forage harvester - Krone brochure. Website www.Krone.de], which are equipped with a removable shield for access to the combine engine maintenance, which protects the engine from environmental pollution.

The closest to the claimed utility model is the John Deer 8300 forage harvester [John Deer 8100-8300 Operation Manual, John Deer. Website www. deere.com], in which the removable shield for access to the combine engine maintenance and protection of the engine from environmental pollution is made of solid metal and covers all the necessary space.

The design of the prototype removable shield of the John Deer 8300 forage harvester has the following disadvantages:

1) the shield is rigidly fixed to the roof of the combine with a bolted connection, therefore, to inspect the engine, it is necessary to dismantle the shield using a tool;

2) the shield is rigidly fixed to the roof of the combine with a bolted connection, therefore, to perform engine maintenance work, it is necessary to dismantle the shield using a tool;

3) the dismantled shield must be taken outside the work area.

The purpose of the utility model is to improve the ease of use of the removable engine shield during the operation of the combine while facilitating access to the engine for its maintenance.

To achieve the specified technical result in the removable engine shield of a forage harvester, which is a one-piece structure made of sheet steel and made of three parts: a central and two outer parts, connected to the upper part of the hood frame with bolted connections, for ease of inspection and maintenance of the engine, the central part of the shield is made with the ability to rotate and is equipped with handles for its installation and dismantling, located on its outer side and attached to it using welded joints. To expand the engine service area, the two outer parts of the shield are dismantled.

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

fig. 1 - removable engine shield;

fig. 2 - general view of the shield installed on the combine.

The inventive removable engine shield includes the following structural elements (Fig. 1, 2): 1 - the central part of the rotary shield for inspection or partial access to the engine; 2, 3 - extreme parts of the shield; 4 - handle; 5 - loop; 6 - fixing screw; 7 - bolt fastening.

The claimed utility model works as follows. To protect the engine from pollution from the environment, shields 1, 2, 3 are installed. To service the engine, it is necessary to loosen the fixing screw 6, turn shield 1 to the required angle around the axis of rotation of hinges 5, while holding the handles 4 with your hands, and unscrew the bolted connections 7 and dismantle shields 2, 3. For inspection or partial access to the engine, it is enough to loosen the fixing screw 6 and turn shield 1 to the required angle around the axis of rotation of hinges 5.

The technical result is to facilitate access to the engine for maintenance.

Claims (1)

A removable shield for the engine of a forage harvester, which is a one-piece structure made of sheet steel and is made of three parts: a central one and two outer parts, connected to the upper part of the hood frame with bolted connections, characterized in that for ease of inspection and maintenance of the engine, the central part of the shield is made with the possibility rotation and is equipped with handles for its installation and dismantling, located on its outer side and attached to it using welded joints.
