Description

FIG. 1 shows a top view of the proposed hand mower; in fig. 2-side view of the mower with a partial cut; in fig. 3-additional third wheel, which serves to set the cutting height; in fig. 4 shows the different positions of the mower when using the extension wheel, and in FIG. 5 and 6 flap guiding mowing.

The mowing machine consists of a stingray light forged. wheels a placed on the axle b. Bushes from these wheels inside have ordinary teeth with dogs for getting a working stroke when the wheels move forward and idle when moving backwards, i.e. when moving forward along with the wheel, the axis rotates, and when moving backward, the wheel rotates and the axis remains stationary.

On axis 5, there is a bevel gear 3 and a coupling with a handle and. The gear has a sliding key and moves to either the right or left wheel by rotating the clutch in a plane, cross-sectional axis.

The purpose of setting the coupling and shifting the gear itself is to

give the whole machine a working or idling. The working stroke will be obtained by moving to the left, when the gear teeth of the gear wheel engages with the teeth of the other gear, and vice versa, the idle stroke will be obtained by shifting the gear gear from the right to the right, when the teeth are separated.

On the axis b there is a bearing w, supporting the vertical axis o, on which gear l is tightly seated, and below it is also serrated gear and chain knife.

Thus, when the mower moves forward, the axis rotates with the wheels, through gear 3, transmits rotational motion to gear l in the horizontal plane.

Frame g, g is pivotally attached to bearings d from the rear side and ends with arms g, g serving to push the mower forward, and at the front the ends of the frame are bent down and spread out to the sides. Between the ends on the bolts, the finger bar W is attached.

Bolts also serve as axes for corner stars.

employees to guide the chain knife y.

In this way, the chain blade, the transition along the finger mowing beam and through the sprockets, is connected in an endless chain and pulled onto the drive pin.

When the mower moves forward, the large gear p rotates and drives the chain knife in the direction of arrow F.

The grass is mowed and the grasses fall between the fingers of the mowing beam and are cut off by the chain knife blades running across the surface of the fingers.

Sun mowed the grass and cereals shaft of the TC through -sosten bar. In order for the grass not to fill up the sides of the thorn and the mechanism of the leading teeth, light brushes of y, g /, g / d are fixed on the vertical shelves of the frame and on the cross member.

In order for the grass not to fall, on the sides, behind the bars, “if the grass is not raised, it does not rise under the angular gears of the mowing beam, mustaches of steel strips are attached to the sides, which fill and distribute the grass.

The mowed grass falls through the sawn timber and, falling under the mower, lies on the path of the mower driving the mower so that the latter is forced to trample the grass. A special device has been made to prevent this: there is a hinge at the rear of the finger bar, coupled with the dividing shield Z (Fig. 5, 6), which has a gable shape, pointing forward. From the plan (Fig. 1), it can be seen that the WIRE has pyramidal inclined planes, thanks to which the mowed grass, slipping along them, falls on two sides, clearing the road in the middle of the road.

The mower can be used for mowing cereals in the form of oats, barley and so on. Then it is necessary to adjust the height of the skive, for over the plowed field

Since .. Ch-sliding of the mowing beam will be very difficult, and the constant support of the mowing beam at a certain height will create a tense and unproductive work of the mower.

To avoid this, instead of a simple flap 2, a flap is inserted into the mower, which has a frame inside which the auxiliary wheel 1 is fitted (Figs. 3, 4, 1). Both frame 2 and wheel 1 are located under the flap z and are pivoted near the hinge u. The frame-2 is provided with a handle 4, in which several holes are made, through which, as well as the throats 5 loops attached to the back plate y, a check is inserted. Putting the checks into the corresponding opening of the cheek adjusts the height of the mowing beam feed (Fig. 4, dotted line).

The subject of the patent.

1.Manual mower with a chain knife, which is characterized by using: a) rotary about the axis of the running wheels of frame g, g, used to strengthen the finger bar W on it, b) axes m, m for sprocket chain knife guides, c) guard plates g /, Y2 and d) rotary near the hinge of the guard 2, the sloping side walls of which are intended for lateral displacement of the falling stems, in order to form a grass-free path for the worker to operate the mower using the handle "1" (Fig 1, 2, 5 and 6).

2. In the mower described in paragraph 1, a device for adjusting the cutting height of bread stalks, characterized by the use of a wheel 1 located under the flap Z, the frame 2 of which is swiveled near the hinge, for mounting the wheel at different heights relative to the finger bar using checks and corresponding holes 3 in the handle 4 of the frame and in the eyelet 5 of the shield y (Fig. 2, 3 and 4).
