Abstract

PURPOSE:To provide the subject simplified compact blower equipped with a fan to throw cut lawn following its suction and a second fan to carry the cut lawn thrown through wind power externally. CONSTITUTION:The objective blower is made up from a double fan which is manufactured by monolithically mutually connecting back to back, through a back plate 18, the surfaces of a throwing fan 16 for a cut lawn carrying blower B and a carrying fan 17.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turf fan for sucking and leasing turf in a mower turf discharger equipped with a rotary cutting blade and a turf blown to the outside. The present invention relates to a blower for mower turf transportation in which a blower having a transportation fan for transportation is provided.

[0002]

2. Description of the Related Art Conventionally, blower throwing fans and conveying fans have been disclosed in Japanese Patent Laid-Open No. 3-108407.
Each of them was independently installed in a blower case.

[0003]

Since the blower as a throwing fan and the blower fan as a conveying fan are separately provided inside the blower case, there is a disadvantage that the blower case becomes large and the outside air The interior of the blower case must be partitioned with a partition wall so that the air flow of the carrier fan that sucked the air does not reach the back of the target fan and disturb the targeting function of the target fan. However, there is an inconvenience that the structure is complicated such that the periphery of the hole of the fan rotation shaft that penetrates the partition wall must be closed via a bearing. The present invention has a simplified structure of a grass cutting conveyor blower,
In addition, it aims to achieve compactness.

[0004]

To achieve the above object, the present invention is characterized in that the throwing fan of the blower for transporting the grass clippings and the transport fan are integrated with their backs through one back plate. It is composed of double fans that are connected in series.

[0005]

As shown in FIG. 1, the turf mowed by the rotary cutting blade 9 is sucked by the centrifugal blower 16 as a blasting fan, and then struck by the fan of the centrifugal blower 16 and blasted upward. At the same time, the thrown grass clippings are blown upward by the carrying wind of the turbo fan 17 as a carrying fan that has sucked in the outside air. And such a throwing fan 16 and a transport fan 1
7 and 7 are constituted by a single double fan whose backs are integrally connected to each other through a single back plate 18, so that the inside of the blower case is partitioned so that the conveying winds do not reach each other. There is no need to provide a partition wall.

[0006]

As a result of the above construction, the partition wall is not required and the bearing for the intermediate portion of the fan rotation shaft is not required, so that the structure of the blower case can be simplified and made compact.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 3, the engine 3 is arranged in the front part of the machine body having the front and rear wheels 1 and 2, the mission case 4 is arranged in the rear part thereof, and the steering wheel 5 and the driving seat 6 are arranged in the center part of the machine body. Then, a mower M is arranged between the front and rear wheels 1 and 2, and a mowing turf conveying blower B provided at a right end of the mower M is used to cut a grass container 8 at the rear of the machine body through a duct 7. A riding lawn mower that conveys turf is configured. As shown in FIG. 2, the mower M has three blade-shaped rotary cutting blades 9 housed in a cutting blade housing 10.
After the driving force of the engine 3 is input through the transmission shaft 11, it is transmitted to the left and right cutting blade drive shafts 9a and 9b by the transmission belt 12 to drive the three rotary cutting blades 9. In the cut grass transport blower B, a fan rotation shaft 15 is driven from a cutting blade drive shaft 9a near the blower B via a transmission belt 13 and a bevel gear mechanism 14.

As shown in FIG. 1, the blower B for transporting the cut grass has a throwing fan 16 composed of a normal centrifugal blower for sucking and throwing the cut grass cut by the rotary cutting blade 9.
It consists of a turbofan 17 for transporting compressed air for wind-transporting the thrown grass to the grass container 8, both of which integrally connect their backs via a single backboard 18. The fan rotation shaft 15 supported in a cantilever manner via the bearing 20 of the blower case 19, the collar 21, and the bolt 2.
It is fixedly connected via 2.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
