US 12,262,657 B2 · Device and method for dispensing a particulate material

Abstract

The invention relates to a method for dispensing a particulate material in a target area and a device suitable for use in the method. The method comprise (i) providing a reservoir comprising openings for the particulate material, (ii) providing a number of closing means suitable for at least partially closing the openings of the reservoir (iii) providing a number of screens in the void of the reservoir, said screens being movable, through the void of the reservoir between at least a first and a second position (iv) loading particulate material in the reservoir, (v) moving the reservoir loaded with particulate material over the target area and at least partially opening the number of openings while alternatingly moving the screens between a first and a second position and vice versa.

A method for dispensing in a target area, a particulate material, the method comprising the steps of:

(i) providing a reservoir for the particulate material, said reservoir comprising a number of openings, suitable to allow particulate material to exit from the reservoir;
(ii) providing a number of closing means suitable for at least partially closing the openings of the reservoir;
(iii) providing a number of screens in the void of the reservoir, said screens being movable, through the void of the reservoir between at least a first and a second position;
(iv) loading particulate material in the reservoir;
and
(v) moving the reservoir loaded with particulate material over the target area and at least partially opening the number of openings while alternatingly moving the screens between the first and the second positions and vice versa;
wherein in the movement between the first and the second positions, the closing of the openings by the closing means is changed.

A device for dispensing a particulate material, comprising:

a body comprising a reservoir for the particulate material comprising a circumferential wall, surrounding a void, and having a first end and a second end at a distance from the first end, wherein the body further comprises a base, the first base, said first base connected to the circumferential wall at the first end closing the void at the first end, said first base provided with a number of openings, suitable to allow particulate material to exit from the reservoir;
a body comprising a number of closing means suitable for at least partially closing the openings of the first base;
and
a body comprising a number of screens, protruding into the void, wherein the screens are moveable, between at least a first and a second position such that in their movement from a first to a second position, the screens push against particulate material, when the particulate material is present in the void, and wherein in the movement of the number of screens between the first and the second positions, the closing of the openings by the closing means is changed.
