Description

"SHARP DEVICE APPLIED TO CHICKEN AND BINDER IN GENERAL"

It addresses the present Utility Model Patent application, in particular a "GENERATOR APPLIED HARVESTING DEVICE AND DEVICE", in particular of an improvement applied to grass chopper and harvester, used in agriculture for weeding and preparation and other green products in silage and or daily animal care, whose characteristics presented in the new model, have great advantages and is configured in an unprecedented device that allows the sharpening of knives present in these equipments.

The device was designed, developed and applied in agricultural equipment, and through it it is possible to sharpen the pruning knives without removing them from the equipment, that is, when we activate this device the knives are sharpened with the equipment running quickly, quickly. and security.

In the current state of the art, the equipment used in agriculture for the harvesting and preparation of green products in silage and or in the daily handling of animals is imported equipment. National equipment is incorporated only as accessories, which are added to the tractor using transmissions to operate the equipment, and such equipment is complex and very expensive, which makes it difficult to implement machinery in agriculture.

In present state of the art models the knives lose their cut quickly according to the time of use and materials to be weeded. With the loss of cut the machine must be stopped so that it can be completely disassembled, the knives removed and sharpened one by one in a non-portable sharpener and in a place for maintenance, causing cost and time of maintenance. With this in mind, the inventor developed an automatic equipment that after several studies meets the needs of the field in a practical, functional, low maintenance cost.

"SAFETY DEVICE APPLIED TO CHAIN AND BINDER IN GENERAL", object of this utility model patent, stands out for presenting in its design conception, a mechanical arm whose one end is coupled with a sharpening stone that in contact with the knives, sharpens simply and effectively.

The device is coupled to the machines and has a drive handle that through pendulum movements provides the edge of the hone with the full length of the knives.

THE "SHARP DEVICE APPLIED TO HARVESTING AND BINDING IN GENERAL", and its applicability will be made known by reading the accompanying illustrative drawings, to which reference is made in order to further elucidate the following detailed description:

FIGURE 1: Side view of the chopper or forage harvester with the knife sharpening device;

FIGURE 2: Top view of the chopper or forage harvester with the knife sharpening device;

FIGURE 3: Front view of the knife sharpening device inserted in mincers or forage growers in general;

FIGURE 4: Perspective view of the knife sharpening device inserted in general mincers or foragers FIGURE 5: Front end view with knife sharpening stone inserted in general miners or foragers;

FIGURE 6: Top view of the knife sharpening device introduced in general mincers or forage grinders;

FIGURE 7: Bottom view of the knife sharpening device inserted into mincers or forensers in general with the safety plate;

FIGURE 8: Front view of the knife sharpening device inserted into mincers or forage harvesters in general with the spring return position.

According to the illustrations presented and in detail the sharpening device applied to the mincer and forage harvester in general (1) consists of a sharpening device (2) comprising a mechanical arm (3), a sharpening stone (4), mounting bolts (5), tension spring (6), movement handle (7), threaded shaft (8), actuation limiters (9) and safety plate (10).

The function of this device is to sharpen the knives (11) of mincers and forage harvesters without removing them and without stopping the machine (1) by means of a pendulum movement that allows the grinding stone (4) to contact the entire surface. knife cutting (11). In the machine (1), a side opening (12) has been introduced in an arc according to the trajectory of the sharpening stone (4) to sharpen all knives (11).

The side opening (12) has a safety plate (10) made of steel that prevents contact of the sharpening stone (4) with the knives (11) when the device is not used, thus the safety plate (10) ) isolates the sharpening stone (4) from the knives (11). The preferably steel-mounted mechanical arm (3) with a reinforced structure designed to withstand the impact of field sharpening keeps the sharpening stone (4) fixed at one end while the other end is directly attached to the machine. (1).

The sharpening stone (4) is fixed and secured to the mechanical arm (3) by means of three fixing screws (5) and when in direct contact with the moving knives (11) and the working machine (1) provide the sharpening them.

The sharpening device (2) allows adjustment of the contact of the sharpening stone (4) with the knives (11) according to the wear and tear suffered by others. This adjustment is made by means of a threaded shaft (8) that approximates or distances the mechanical arm (3) from the equipment (1). The tension spring (6) is designed to keep the mechanical arm (3) always in the same starting position facilitating the work of the operator who performs a single effort during movement of the device (2). The tension spring (6) is attached to one of the actuation limiters (9) and one of the screws (5) that fixes the mechanical arm (3) to the equipment (1).

The operator moves the sharpening device (2) through the movement handle (7) which moves the mechanical arm (3) in a pendulum path for knife sharpening (11). The actuation limiters (9) always keep the device (2) in the same area of action, ie limiting both upper and lower movement and sharpening the full length of the knife blade (11).

The "SHARPED R APPLIED DEVICE IN GENERAL FORCING AND FORCING" gives grinders and forks great agility and safety when sharpening knives (11) by cutting and is a device (2) that allows quick and easy change of grinding stone. (4) after wear by fixing screws (5).
