Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial field of application) The present invention relates to air blown to a radiator core of an engine of a working vehicle that generates large dust such as grass chips of a self-propelled mower. The present invention relates to an air dust removing device for removing dust inside to prevent clogging.

(Prior art and problems to be solved) Conventionally, in a self-propelled mower, etc., in order to prevent large dusts such as generated grass particles from adhering to the radiator core and causing clogging, the front of the radiator core is prevented. Although a filter such as a wire net was provided in the above, the wire net was clogged by large dust such as grass pieces, and removal and cleaning of the dust were troublesome.

[Structure of Invention]

(Means and Actions for Solving the Problem) The present invention provides a crusher equipped with a crushing grid and crushing blades in front of a centrifugal separator for removing minute dusts, and crushes large-scale dusts to generate minute dusts. This is dust, and this minute dust is removed by a centrifugal separator, and the air from which the dust has been removed is blown to the radiator core.

Embodiment An embodiment of the present invention will be described below in detail with reference to the drawings.

The radiator core 1 circulates the cooling water of the engine and allows the suction air of the air intake fan 5 driven by the electric motor 3 to pass therethrough,
This cooling water is cooled. In front of the radiator core 1, a crusher 11 having a crushing grid 7 and crushing blades 9 is provided. That is, the crushing grid 7 is a cylindrical portion 13 as an air suction tube.
A blade portion 19 is provided at the edge of the radial crushing hole 17 that is fixed inside the ring body 15 that is fixed inside. The crushing blade 9 has a blade portion 23 formed on the edge portion of the inclined blade plate 21 on the crushing grid 7 side and is rotated by a motor to have a blowing function. A plurality of centrifugal separators 25 are provided between the crusher 11 and the radiator core 1. That is, the inside of the cylindrical portion 13 is partitioned by the front partition plate 27 and the rear partition plate 29 to form a dust collection chamber 31, and a large number of centrifugal separators 25 are provided inside. That is,
One end of a cylinder 33 is fixed to the front partition plate 27, communicates with an inflow port 35 penetrating the front partition plate 27, and the other end is opened in the dust collection chamber 31. The small diameter portion of the conical cylinder 37 is inserted in the central portion near the rear end of the cylinder 33, and the large diameter portion communicates with the outflow port 39 of the rear partition plate 29. At the front end of the cylinder 33, a plurality of fixed blades 41 inclined in the circumferential direction are arranged side by side in the circumferential direction. A dust pipe 43 communicates with the bottom of the dust collection chamber 31 and opens to the atmosphere.

In the above embodiment, the air containing dust passes through the crushing holes 17 of the crushing grid 7 and is sucked into the crushing blades 9 by the suction force generated by the rotation of the crushing blades 9 of the crusher 11. Large dust is crushed between the blade portion 19 and the blade portion 23 of the blade 21 to be fine dust, and the dust is sent to the centrifugal separator 25 together with the blown air. This blast enters the cylinder 33 through the inflow port 35, and the fixed blade 41
And the dust in the air is blown by the centrifugal force into the cylinder 33.
Along with the inner wall of the dust collector, it enters the dust collection chamber 31 together with part of the blown air and is discharged to the outside from the dust discharge pipe 43. The blown air from which dust has been removed is sent from the conical cylinder 37 to the radiator core 1 through the outlet 39, is sucked by the suction fan 5 and passes through the radiator core 1 to cool the cooling water.

〔The invention's effect〕

The present invention, after crushing a large amount of large dust such as grass fragments of a mower and removing it by a centrifuge, by sending to the radiator core, to prevent large dust from adhering to the radiator core, Moreover, even if the blown air is sucked into the vaporizer, it is possible to prevent the dust from being sucked, and since a filter, a wire mesh, and the like are not used, clogging does not occur and maintenance is easy.
