Problems solved by technology

However, in known spreading devices, the use of grit often leads to clogging of the metering or conveying rollers, which is why a particularly powerful electric motor is used as drive and the parts of the spreading device are designed to be particularly robust
This increases not only weight but also cost and often increases the installed size of the corresponding unit

Embodiment Construction

[0023] figure 1 A schematic view of a device 1 for spreading gravel 2 in front of wheels 3 of a vehicle 4 is shown. The device 1 is arranged at a suitable position on the vehicle 4, below the container 15 of the gravel 2, so that the gravel 2 can be distributed to the desired place in front of the wheel 3, and the static friction between the wheel 3 and the ground can be increased so that Facilitate starting or shorten braking distances.

[0024] figure 2 A sectional view of an exemplary embodiment of a device 1 for spreading gravel 2 according to the invention is shown. The device 1 comprises a housing 5 having a feed inlet 6 for the gravel 2 which coincides with a corresponding outlet of a container 15 for the grit 2 . Ideally, the walls of the container 15 are configured to be sloped to facilitate the sliding of the grit 2 stored in the container due to gravity. In the housing 5 there is provided a substantially cylindrical recess 8 in which a rotatably mounted and dri...

Abstract

The invention relates to a device (1) for scattering grit (2) in front of the wheels (3) of a vehicle (4), comprising a housing (5) provided with a feed inlet (6) for the grit (2), an outlet (7) for the grit (2), and a substantially cylindrical recess (8) for receiving a brush roll (9), which is rotatably mounted and rotatably driven about a substantially horizontal axis of rotation (A), for the dosed delivery of the grit (2) from the feed inlet (6) to the outlet (7). According to the invention, at least one wedge (10) is arranged in the region of the feed inlet (6) for the grit (2), in frontof the brush roll (9) and tangentially and movably in relation to said roll (9), such that the size of the feed inlet (6) can be adjusted.

Description

technical field [0001] The invention relates to a device for spreading grit in front of the wheels of a vehicle, comprising a housing having a grit inlet, a grit outlet, and a substantially cylindrical housing for receiving a brush roller. The brush roller is rotatably mounted and driven about a substantially horizontal axis of rotation for metered delivery of grit from the feed inlet to the outlet. Background technique [0002] If the static friction between the vehicle's wheels and the ground is insufficient, there is a risk that when starting the vehicle, the drive wheels will spin due to insufficient traction, and during braking, the wheels will slip on the ground, causing the braking distance too long. Therefore, a sand or gravel spreader is used, wherein sand or gravel is spread in front of the wheels to increase static friction to facilitate starting of the vehicle or shorten braking distances. [0003] For example, US 1,793,689 A describes a sand spreading device w...
