Abstract

PURPOSE:To guide discharge of collected grasses from discharge port of a mower deck by a guide fan to smoothly carry out the discharge and simplify the structure of a mower deck. CONSTITUTION:A mower deck constituted by providing, in the inner circumference face 3 of the mower deck 2 covering rotatable peripheral part of a blade 1, a reinforcing board 6 capable of covering the inner circumference face 3 and simultaneously forming an upward inclined guide fan 5 in the discharging direction near the side of a discharge port 4 of collected grasses.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mower deck structure.

[0002]

2. Description of the Related Art A mower deck covers a blade which rotates in a horizontal plane, and a bottom surface of the mower deck is opened for cutting grass. For this reason, when the collected grass is not swiftly discharged to the discharge port, the blade rotating on the bottom surface is repeatedly touched and is likely to be cut twice. For this reason, guide fins for promptly guiding the discharge to the grass collection discharge port for discharging the cut grass are provided on the mower deck with a simple structure.

[0003]

The present invention is a blade 1
On the inner peripheral surface 3 of the mower deck 2 which covers the rotating peripheral part of the above, a reinforcing plate 6 is provided which covers the inner peripheral surface 3 and forms a guide fin 5 that is inclined upward in the discharging direction near the grass collection outlet 4 side. It will be a moor deck configuration.

[0004]

By the rotation of the blade 1,
The grass that is guided inside the mower deck 2 has been cut,
It is collected to the discharge port 4 side in the rotating direction and discharged from the discharge port 4 to the outside. At this time, the grass collection in the mower deck 2 is guided along the inner peripheral surface 3 by the centrifugal action, and the discharge port 4
Is discharged to.

Since the inner peripheral surface 3 is covered with the reinforcing plate 6, even if the inner peripheral surface 3 is rubbed by the grass, the mower deck 2
The main body is not worn, and moreover, the guide fins 5 of the reinforcing plate 6 itself are less likely to drop and contact the rotating blade 1 during discharging.
Stagnation near the discharge port 4 is reduced, and grass collection and discharge are performed quickly.

Moreover, since the guide fins 5 are formed on a part of the reinforcing plate 6, the guide fins 5 can be attached by attaching and detaching the reinforcing plate 6, and maintenance such as construction and attachment / detachment is easy. .

EXAMPLE A mower deck 2 is formed in a dish shape by molding or the like, and an engine 7 is provided on the central upper surface of the ceiling portion of the mower deck 2 so that a vertical blade shaft 8 is projected downward from the ceiling portion. And attach the blade 1 to the lower end. By driving the engine 7, the blade 1 can be rotated at high speed to mow grass. A blade 9 is formed at the tip of the blade 1 on the side opposite to the blade edge 10 to collect grass to be cut.

The inner peripheral surface 3 has a cylindrical shape which approaches the rotating surface of the tip of the blade 1, and a wear resistant reinforcing plate 6 is attached along the inner peripheral surface 3. A guide fin 5 is formed on the inner peripheral surface of the reinforcing plate 6 near the discharge port 4 which is open at the rear side of the mower deck 2, and is inclined upward in the discharging direction. The guide fin 5 is discharged along the surface of the reinforcing plate 6. Guide the turf grass to the upper part. The mounting structure is such that a hook 11 fitted from below to the lower edge of the mower deck 2 is attached to the lower edge of the reinforcing plate 6 by welding or the like.
The fastener 1 is detachably fastened to the mower deck 2 with the fastener 12. The reinforcing plate 6 may be made of steel or a wear-resistant synthetic resin material.

Numeral 13 is a turf grass guide edge integrally formed on the front side of the mower deck 2, which is a state where the turf grass is pushed down to the front side.
Guide to the inner circumference. Reference numerals 14 and 15 are gauge wheels attached to the front and rear of the mower deck 2. Reference numeral 16 denotes an under cover that is attached along the bottom surface of the discharge port 4, and is detachably attached to the lower end edge of the mower deck 2 with a fastener 17 such as a bolt. Reference numeral 18 denotes an operation handle that projects rearward from the discharge port 4 side, 1
Reference numeral 9 is a collector case that houses grass that is discharged rearward from the discharge port 4.

In FIGS. 4 to 6, the collector case 1 is shown.
9 is attached to a handle 18 so as to be vertically rotatable by a shaft 20 and a pair of handles 21 is pushed forward to the collector case 19 to open the opening 22 at the front end of the collector case 19 to the outlet 4 of the mower deck 2. The turf grass discharged from the discharge port 4 can be stored in the storage bag 23 inserted in the collector case 19 at this time. Further, by pulling the handle 21 backward, the collector case 19 can be inverted and the turfgrass-accommodating bag 23 can be dropped and discharged downward from the rear opening 24. Reference numeral 25 denotes a lid provided on the handle 18, which closes the opening 24 on the rear side when the collector case 19 is in a bag-filled state (FIG. 4).

The bag 23 used at this time is composed of a cylindrical bag material 26 which is long and continuous in a staggered manner, and a separation eye 27 for each bag size.
To form the knot 2 along the bag mouth of each bag material 26.
8 and 29 are separated from the bag material 26 for each bag, and the string 28 at the bottom is tied and inserted into the collector case 19, and when taken out from the collector case 19, the string of the other bag mouth. Tie 29 and carry it.

7 and 8 are different from the above example in that
When the operation handle 18 and the collector case 19 are integrally rotated about the shaft 20 and the collector case 19 is discharged and rotated, the operation handle 18 is grounded as shown in FIG. In addition, the lid 25 has a pivotal support 30 structure that can be rotated with respect to the handle 18. When the lid 25 is tilted downward, the bag 23 containing turfgrass can be dropped.
