Abstract

PURPOSE:To reduce the clogging of mowed lawn grass in a carrying route ranging from the lawn grass-collecting opening of a mower deck to a chute when the lawn grass mowed with a mower attached to a tractor is collected and carried into a collector. CONSTITUTION:A guide cylinder surface 6 swollen on the upper side than a lawn grass-collecting opening 2 is formed in a chute 5 communicating with a sucking blower 4 and with the lawn grass-collecting opening of a mover deck 1.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mower grass collection and conveyance device mounted on a tractor.

0002

[Prior Art and Problems to be Solved by the Invention] In order to convey the grass cut by a mower to a collector, a chute is provided at the grass collection port on one side of the mower deck, but the connecting part between the mower deck and the chute is Transport of turfgrass tends to become clogged. The present invention is intended to reduce such clogging with grass due to the shape of the chute.

0003

[Means for Solving the Problems] The present invention includes a chute 5 that communicates with the grass collection port 2 of the mower deck 1 and that receives the collected lawn grass cut by the rotary cutting blade 3 and suctions and conveys it to the suction blower 4 side. The structure of the mower's grass collection and conveyance device is such that a guide cylinder surface 6 is formed that bulges above the grass collection port 2.

0004

[Operation and Effects of the Invention] Lawn grass cut by the rotation of the cutting blade 3 of the mower deck 1 is collected at the grass collecting port 2, fed into the chute 5, and is conveyed by suction within the chute 5. Inside this chute 5, the cross-sectional area is wider than that of the grass collection port 2, and the guide cylinder surface 6 is bulged upward, so that
The grass is less likely to directly collide with the guide cylinder surface 6 and receive a large resistance, and is quickly suctioned and conveyed by the blower 4.

[0005] As described above, depending on the shape inside the shooter 5,
It is possible to reduce the amount of grass that collides with the guide cylinder surface 6 and receives resistance, and the suction blower 4 can quickly carry out the suction conveyance, thereby reducing clogging of the grass and simplifying the configuration. .

[0006]

[Embodiment] In FIGS. 1 to 5, the chute 5 has a connecting port 7 that fits into the grass collection port 2 of the mower deck 1 at one end, and a discharge port 9 that is inserted into the chute 8 made of a bellows at the other end. A guide cylinder surface 6, which is an upper surface, is bulged upward and extends between the connecting port 7 and the discharge port 9, and has a cross-sectional area larger than that of the grass collecting port 2. There is. Further, the bottom surface of the chute 5 has an inclined guide surface 10 that is inclined upward in the conveying direction.
, 11 and the stepped portion 1 between the front and rear inclined guide surfaces 10 and 11
2. An intake port 13 through which outside air can be sucked is formed on the upper side of the guide cylinder surface 6, and an intake port 14 is formed in the stepped portion 12.

The mower deck 1 has a plurality of cutting blades 17 which are rotatably transmitted with a cutting blade axis 15 directed in the vertical direction and which form wind blowing blades 16, and the mower deck 1 has a plurality of cutting blades 17 which are rotated vertically and which are arranged to form wind blowing blades 16. A grass collecting passage 18 for collecting and conveying the grass is formed, and one end of this passage is used as a grass collecting opening 2. Reference numeral 19 denotes a gauge foil provided on the lower side of the mower deck 1. Such a mower deck 1 includes a tractor body 2 having front wheels 20 and rear wheels 21.
It is attached to the abdomen of the patient and is linked by a power extraction shaft. A collector 23 is mounted on the rear of the vehicle body 22,
A suction blower 4 is installed on the same side as the grass collection port 2 of this collector 23.
is provided so that the upper end of the chute 27 of the suction blower 4 communicates with the inside of the collector 23. Also, this suction blower 4
A suction port 2 formed on the front surface in the direction of the axis 28 of the suction fan 25
6 and the discharge port 9 of the chute 5 are connected by a chute 8.

The grass cut by the cutting blade 17 in the mower deck 1 is collected through the grass collecting passage 18 and fed into the chute 5 through the grass collecting port 2 on one side, and is moved into the chute 8 by the suction force of the suction blower 4. is conveyed by suction, and the suction blower 4
From there, the liquid is blown and conveyed into the collector 23 via the chute 27, forming a series of conveyance paths. The suction blower 4
An opening 30 is formed in a portion extending from the outer circumferential wall 29 where the suction fan 25 rotates to the shooter 27, and this opening 30 faces the center side of the collector 23. An elastic plate 31 made of rubber or the like is provided outside this opening 20. Due to the high speed rotation of this suction fan 25, the suction port 2
If there is any foreign matter such as stones in the cut grass that is conveyed from the lawn mower 6 toward the chute 27, it is discharged from the opening 30. In addition, since this opening 30 faces the inside of the machine body and there is an elastic plate 31 on the outside, stones etc. are not directly scattered outside, and the operator does not have to insert his/her hand directly into the opening, making it safe. .

The grass fed into the chute 5 from the weed collection port 2 is guided upward along the inclined guide surface 10 at the bottom, but since the upper guide cylinder surface 6 is bulged,
It is difficult to collide with this guide cylinder surface 6, and the grass is conveyed smoothly from the chute 5 to the chute 5 by suction conveyance by the suction blower 4. It is possible to reduce turbulence and stagnation in the flow, thereby reducing conveyance jams.

[0010] Reference numeral 32 is a pilot's seat, and 33 is a bonnet, under which an engine is mounted and a control handle is provided at the rear. 6 and 7, the difference from the above example is that the bulge of the guide cylinder surface 6 on the upper side of the chute 5 is formed into a gentle slope.
