On the frame of the harvester, two pneumatic cylinders driven by the pneumatic system of the combine are fixed, located horizontally and perpendicular to the rollers. EFFECT: increased reliability, reduced dimensions of the regrinder movement mechanism and the number of parts, exclusion of environmental pollution in the absence of hydraulic fluid. 4 ill.

Description

The utility model relates to agricultural engineering, namely to forage harvesters equipped with grain refiners designed to crush corn grains in the phase of their waxy ripeness. One of the components of the grinder is the movement mechanism.

Website www.Krone.del, whose chopper movement mechanisms are made both manually (CLAAS Jaguar 870, Jaguar 980) and remotely installed from the cab (John Deer 8800, 8300, New Holland FR780, Krone Big X 530, Big X 580, Big X 630). The regrinder is moved using screw mechanisms and hydraulic cylinders with levers.

Closest to the claimed utility model is the chopper of the Krone forage harvester [4], which contains a spacer, a grain crusher housing, rollers, bearing supports, compression springs and a lever mechanism for moving the chopper.

The disadvantage of the design is a complex scheme of levers, the use of hydraulic fluid and a large number of structural components and parts used to move the grinder.

The objective of the utility model is to reduce the dimensions of the regrinder movement mechanism, reduce the number of parts, eliminate the use of hydraulic fluid, increase reliability and eliminate environmental pollution in the event of a hydraulic fluid leak.

The technical result is achieved due to the fact that two horizontally located pneumatic cylinders are introduced into the design of the grinder, which contains a spacer structurally connected by means of bolt fasteners, a grain crusher housing, rollers rotating in bearing supports, and compression springs, two horizontally located pneumatic cylinders are introduced, fixed on the frame of the harvester with the help of bolt fasteners and being independent movement mechanism and regrinder support, which are driven by compressed air, while two hydraulic cylinders are located horizontally and perpendicular to the rollers, driven by the pneumatic system of the combine, and the spacer and grain crusher are bolted to the pneumatic cylinders.

Pneumatic cylinders are mounted on the frame of the combine, they are both the support of the regrinder and its driving mechanism, and provide the rectilinear movement of the regrinder. The regrinder is a combined design consisting of a spacer and a grain crusher, which consists of a housing, two rollers, bearing supports and compression springs. The regrinder allows you to quickly switch the grain crusher to the working position when changing the crops mowed by the combine. Pneumatic cylinders make it possible to reduce labor costs, speed up and facilitate the switching of the regrinder to the working position of the grain crusher for grinding various types of crops.

The claimed device is illustrated by drawings:

figure 1 - grinder in the working position;

figure 2 - grinder in working position, bottom view;

figure 3 - spacer in the working position;

figure 4 - spacer in the working position, bottom view.

The inventive mechanism for moving the chopper of a forage harvester includes the following structural elements: 1 - pneumatic cylinder for moving the chopper; 2 - spacer; 3 - body of the grinder; 4 - bolt fasteners; 5 - roller; 6 - bearing support; 7 - spring, - while the spacer 2 and the chopper body 3 are one functional system. Spacer 2 with grinder 3 are fixed on two horizontally located pneumatic cylinders with the help of bolt fasteners.

The claimed device works as follows.

The operator remotely, from the cab of the harvester, sets the operating mode "Space in the working position", while pressure is supplied to the pneumatic cylinders 1 in the form of compressed air, and the chopper moves from the position "Chopper in the working position" (figure 1, 2) to the position " Spacer in working position" (figure 2) and back. When the operator selects the “Chopper in working position” mode, the pneumatic cylinders 1 move the chopper, which contains spacer 2 structurally connected by means of bolt fasteners 4, chopper body 3, rollers 5 rotating in bearing supports 6, and springs 7, from the position “Space in working position” (figure 3, 4) in the position "Regrinder in working position" (figure 1, 2).

The technical result consists in increasing the reliability of the regrinder movement mechanism and in improving the consumer qualities of the forage harvester by simplifying the design scheme of the device, reducing the overall dimensions of the regrinder and eliminating the ingress of hydraulic fluid into the environment.
