Abstract
Description
Technical field:
[0001] The invention relates to a portable spreading system primarily intended for winter service and de-icing work, in particular for the targeted application of solid spreading material such as grit, granules or salt on sidewalks, stairs, platforms, narrow traffic areas and similar areas.
[0002] Furthermore, the spreading system can also be used for other applications where solid materials need to be distributed in a metered manner, for example in gardening and landscaping, in municipal maintenance work on paths and squares, in industrial and commercial yards, in animal husbandry for spreading bedding or granules, on construction sites for distributing sand or gravel, as well as in the area of facility management and the maintenance of outdoor facilities. Object of the invention
[0003] The object of the invention is to provide a spreading system that enables controlled spreading similar to hand spreading, but reduces frequent manual refilling, avoids work interruptions and reduces the physical strain on the user. Solution to the task
[0004] This task is solved by a two-part spreading system, consisting of a portable storage container for spreading material, a hand-held spreading device in the form of a spreading bucket, and a connecting device between the storage container and the spreading device.
[0005] The hopper is worn by the user, preferably as a backpack, and serves as the main storage container for the spreading material. The handheld spreader is used for the targeted and controlled application of the spreading material. During operation, the spreading material is fed from the hopper into the handheld spreader via the connecting device as needed. Preferred embodiments
[0006] The storage container preferably has a capacity of approximately 15 to 25 kilograms of spreading material. The hand-held spreader preferably has a capacity of approximately 2 to 5 kilograms of spreading material.
[0007] The connecting device is designed as a hose or pipe and has a sufficiently large cross-section to reliably convey even coarse-grained spreading material, especially grit with a grain size of about 2 to 5 millimeters.
[0008] The storage container contains a movable element inside, in particular a rotatable or pivotable stirring element. This serves to keep the spreading material in motion and to prevent bridging or blockages. A material dispensing opening or valve is arranged on the storage container, through which spreading material is dispensed into the connecting device.
[0009] The hand-held spreader is designed as an ergonomically shaped spreader bucket with a handle that allows for secure, one-handed grip and operation. The spreader features two separate controls. The first control activates the spreading function to dispense the material contained within the spreader.
[0010] A second control element serves as a momentary refill function. While this element is activated, the material dispensing opening or valve on the hopper is opened, and the agitator is simultaneously activated, allowing spreading material to be fed into the handheld spreader via the connection device. When the second control element is released, the material dispensing opening closes and the agitator stops, preventing further spreading material from being fed in. Advantages of the invention
[0011] The spreading system according to the invention enables an ergonomically improved and efficient working method, combining the advantages of manual spreading with reduced physical strain. The targeted refill function, which can only be activated when needed, minimizes work interruptions and enables a controlled, safe spreading process, particularly on narrow traffic areas, sidewalks, and stairs.
