JPH059224U - Claw Arrangement Device for Flair More Drum - Google Patents

Abstract

(57) [Abstract] [Purpose] It is an object of the present invention to obtain a claw arranging device for a flair mower drum that does not require a balancer. [Structure] Since a pair of claws that are at the same distance and are out of phase with each other by 180 ° are evenly distributed over the drum circumference 360 °, vibration is extremely reduced.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a claw arranging device for a Freurmore drum.

[0002]

[Prior Art]

 The flail mower is a rotary blade mower with a horizontal axis and has the same principle as the flail forge harvester. It is a type in which the grass is pushed down forward by the roller and then mowed. In the conventional flare mower claw arrangement described above, a balancer is provided at the end of the drum in the vibrating retainer in three to four straight lines.

[0003]

[Problems to be solved by the device]

 As described above, since the flare mower claws are arranged on the drum in three to four straight lines, vibration is generated, and a balancer is required at the drum end to suppress the vibration. Therefore, the object of the present invention is to obtain a claw arranging device for a flair mower drum that does not require a balancer.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides the following claw arranging device in a flair mower drum. That is, it is a claw arranging device in a flair mower drum in which the claws are arranged in a single-row or double-row spiral claw arrangement such that the claws are arranged at the same distance and 180 ° out of phase with the drum. .

[0005]

[Action]

 Due to the same distance, the claw bears that are 180 ° out of phase are evenly distributed around the drum circumference 360 °, so the vibration is extremely small and no balancer is required.

[0006]

【Example】

 Embodiments shown in the drawings will be described below. 1 has two rows of claws spirally arranged on the drum (1), (2) shows one row of claws, and (3) shows another row of claws. The nails (2) (2) in each row are at the same distance (a), and the other nails (3) (3) are also at the same distance (a), and the nails (2) and the nails (3) And are 180 degrees out of phase. When the pawls are arranged as described above, the diagonal pairs of the pawls (2) and (3) are evenly distributed over the drum circumference of 360 °. Therefore, the centrifugal force of the claw acting on the drum becomes a couple, and the force is evenly distributed in a spiral shape, so that the vibration becomes extremely small. Therefore, since a balancer is not required and the spiral direction is the same, it is possible to collect grass on one side. Then, since each claw uses the same flare claw as shown in the figure, the cuts are beautiful.

2 has two rows of claws spirally arranged on the drum (4) as in FIG. 1, but the spiral pitch interval is shorter than that in FIG. As shown, each row of claws (5) (5) are at the same distance (b) and the other claws (6) (6) are also at the same distance (b) and are a diagonal pair of claws. (5) and the claw (6) are out of phase by 180 °. In this case as well, the grass can be collected on one side as in the case of Fig. 1, and no balancer is required.

FIG. 3 shows that there are two spiral claw rows (8) (9) and (10) (11) symmetrically from the longitudinal center of the drum (7) to the left and right. And the nails (8) (8) are equidistant (c), the nails (9) (9) are also equidistant (c), and the pair of nails (8) (9) is 180 ° Out of phase. Further, the nails (10), (10) and the nails (11), (11) are also equidistant (c), and the paired nails (10), (11) are out of phase by 180 °. Also in this case, since the claws are arranged at the same distance with respect to the drum and 180 ° out of phase with each other, diagonal pairs of the claws are evenly distributed with respect to the drum circumference of 360 °. become. Since the spirals extending from the drum center to the left and right ends are symmetrically arranged, the centrifugal force of the claws acting on the drum acts on the drum as a couple, and the force is evenly distributed in a spiral shape. Since the vibration is extremely small, the balancer becomes unnecessary and the grass can be collected at both ends. The spiral of the present invention may be left-handed or right-handed.

[0009]

[Effect of the device]

 According to the present invention, the centrifugal force of the claw acting on the drum acts on the drum as a couple, and the force is evenly distributed in a spiral shape, so that the vibration becomes extremely small and a balancer is not required. , Depending on the spiral direction, the grass can be collected on one side only or on both ends.
