Abstract

PURPOSE:To prevent the abrasion of the bottom part of a chuter made of a plastic by attaching a fitting tool to the lower part of the connection port of a chuter to be attached to the discharging port of a mower deck and connecting the fitting tool to the discharging port of the mower deck. CONSTITUTION:A cylindrical chuter 6 for guiding mowed grass to a grass- collecting container is attached to a discharging port of a mower deck to hold mowing edges 3... by attaching a band-shaped fitting tool 7 to the lower part of the connection port of the chuter 6 and connecting the tool 7 with the discharging port 4. The breakage of the lower part of the plastic chuter by the contact with ground and the damage of the connection port of the chuter with pebbles mixed in the mowed grass can be prevented by the use of the above apparatus.

Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to a chute for a lawn mower.

[Prior art and its problems] Conventionally, in this type of device, one side of the mower deck that covers the circumference of a plurality of cutting blades is opened to form a discharge port, and a cylindrical chute made of resin is connected to this. The structure is such that the cut grass is collected through this chute into a grass collection container mounted at the rear.

However, such conventional devices have the disadvantage that the lower part of the chute comes into contact with the hard ground and wears out during lawn mowing work.

[Means for Solving the Problems] The present invention is proposed in view of the above-mentioned problems, and provides a lawn mower equipped with a highly durable chute that can prevent the chute from being worn out due to contact with the ground. With the aim of obtaining the following, the following technical measures were requested.

That is, one side in the lateral direction of the mower deck 1 that accommodates a plurality of cutting blades 3 arranged side by side in the left and right direction is set as the discharge port 4,
A cylindrical chute 6 that guides the cut grass to a grass collection container attached to the rear is connected to the discharge port 4, and a strip-shaped metal fitting 7 is attached to the lower part of the connection port of the chute 6 to connect soil. This is a lawn mowing device with special features.

[Example code] Hereinafter, the present invention will be described in detail based on the drawings.

First, to explain the structure, numeral 1 is a mower deck that is attached to the abdomen of a riding lawn mower (not shown) so that it can be raised and lowered freely.Inside the mower deck 1, eight cutting blade drive shafts 2 are rotatably mounted. A cutting blade 3 in the form of a strip is fixed to the lower part of the drive shaft 2. A belt is attached to a pulley (not shown) on the drive shaft 2 so that all of the mower blades 3 rotate in the training direction, and the right side of the mower blade 1 is opened to discharge the cut grass [14] is formed. Reference numeral 5 denotes a cut grass discharge passage formed at the upper front side of the moadetsuki 1. When viewed from the rear, it is constructed so that it is one step higher than the top surface of the main body of the moadetsuki, and the discharge passage C10 is gradually higher than the opposite side (the left side in the figure). It is composed of 6
is a resin chute that is detachably connected to this discharge 1 4. The shape of the connecting part 1 is rectangular, and the rear part is a cylinder with a circular mouth shape. This chute 6 guides and guides cut grass and other grass to a grass collection container attached to the rear of the machine, and the wind generated by the cutting blades 3 rotating inside and outside the mower deck 1 causes the grass clippings to pass through the chute 6 from the discharge port 4. The grass passes through and is collected in the grass collecting container. Shooter 6
The lower part of the connection port has a 7-shaped notch in the center when viewed from above, and the cutting blade 3 located on the outer side of the cutting blade 3 is inserted into this notch.
Adjust the relationship between the two ministries so that their rotational trajectories become closer.
(Fig. 2) ■ is a band-shaped metal fitting that protects the lower part of the connection port of this chute 6. The front and rear parts are bolted to the lower front and rear parts of the chute 6, and the middle part follows the shape of the lower part of the chute 6. The metal fitting 7 protects the end surface of the chute 6 on the mower deck 1 side and the side in contact with the ground.

Fig. 5 shows the cross-sectional structure of the mounting section, in which a long hole 8 is bored in a part of the resin chute 6, and a protrusion 9 formed on the folded part 7a of the metal fitting 7 is inserted and locked. This shows the state in which it is configured so that it can be used.

When mowing the lawn in such conditions, the three cutting blades 3
The cut grass and grass are sent to the chute 6 side through the cut grass discharge passage 5, and further sent from the chute 6 to a grass collection container attached to the rear of the machine. When moving the machine forward to perform reaping work, the lower part of the connection port of the chute 6 may come into contact with the ground. In this embodiment, a band-shaped metal fitting 7 is attached to the lower part of the connection port, and this metal fitting 7 Since it is attached to the connection port of the chute 6 so as to wrap around the end face of the mower deck 1 and its two sides, there is no risk of damaging the lower part of the resin chute 6, or of cuttings etc. being sent to the chute 6 side during rotation. The chute 6 is prevented from being hit by pebbles mixed in with it and damaging the chute 6, and the end face of the chute 6 is covered with a metal fitting 7, which prevents cut grass or grass from getting caught. Therefore, it has the feature that the grass clippings can be effectively discharged from the mower deck.

[Effects of the Invention] Since the present invention is configured as described above, it has the following technical effects.

That is, when attaching the chute 6 to the discharge port 14 on the mower deck, a metal fitting 7 is attached to the lower part of the connection port side of the chute 6, and this is connected to the discharge port 4 of the mower deck 1, so that the resin There is no problem that the bottom of the chute 6 contacts the ground and causes damage, and the durability of the resin chute 6 can be improved.

Claims (1)

[Claims] One side in the horizontal direction of the mower deck 1 that accommodates a plurality of cutting blades 3 arranged side by side in the left and right direction is defined as a discharge port 4, and this discharge port 4 has a grass collection container attached to the rear. This lawn mowing device is characterized in that a cylindrical chute 6 for guiding cut grass is connected, and a band-shaped metal fitting 7 is attached to the lower part of the connection port of the chute 6.
