Rubber feed- and silage scraper (RVSKS)
The rubber feed- and silage scraper is, like the other Kemp feeders, capable of swivelling 70 degrees, left and right. Because the slide swings 70 degrees, the feed can be slide well towards the cows and it will not start to accumulate. In addition, it is important that the feed is placed next to the vehicle, so that the vehicle does not drive over the feed. Therefore, it is important that the scraper can pivot. Pivoting 70 degrees is possible through the use of two hydraulically driven cylinders. The second advantage of these two cylinders is that there is more power to pivot the scraper during feeding.
The next advantage of the Kemp feed scrapers is that they can oscillate. This means that the rubber strip can move with respect to the mounting frame. The advantage is a good ground adaptation and uniform wear of the rubber.
It is important that the feed is pushed next to the vehicle. The slider is thus available in several sizes, so that there is a suitable scraper for every vehicle.
The core task of the feed sliders is of course the feeding of feed, however, the slide can also be used as a mud slide, snow blade, to slide away any residual feed or to push the sand away on the silage pit. And that last is exactly what the RVSKS is particularly good at.
The all scraper. With this scraper; feed can be pulled up, the sand is pushed out of the silage, or moved. And muddy yards and snow can be removed.
The RVSKS has two pivot points and four cylinders. The pivot point near the connection has the same function as the other feed scrapers. When this first pivot point is pivoted, the rubber can be held in a 180 degree position with the other pivot point. This moves the centre of the rubber from out the centre of the vehicle. This is possible up to 700 mm. Because the rubber gets 'longer' from out the centre of the vehicle, the sand can be pushed out of the silage pit. The second advantage of a double pivot point is that the slide can pivot even more than 70 degrees.
The RVSKS comes standard with the rubber 2.800*500*50 mm. In this rubber two rows of holes are drilled, allowing you to turn over or lower the rubber when one side is worn.
The rubber feed- and silage scraper is available with the attachments that belong to your vehicle (for the attachment parts, see the document: Kemp attachment parts).
For additional specifications, see the document: product specifications.
Adjustable angles (manually): The feed scrapers are standard equipped with a straight beam, however it is also possible to choose for manually adjustable angles. These angles can be adjusted 35 degrees with respect to the beam. The adjustable angles give you more control to keep the feed near the rubber and thus slide away in the direction of travel.
Due to the fact that the RVSKS has two pivot points, two hydraulic functions must be operated. If the vehicle has one double-acting valve, you can choose with a 6/2 control slide from the driver's seat which function is to be operated.
The second option is a 3-way ball valve, which allows you to manually select which function to operate.
Shock valve: a shock valve is needed with vehicles above 4,000 kg. The shock valve provides protection when the scraper collides with something. In this case, the shock valve ensures that the oil from the cylinder, which has come under pressure, is moved to the other cylinder. As a result, the scraper swings past the obstacle and the chance of damage is reduced. The shock valve is of course only possible with two cylinder scrapers.
Pilot operating non return valve: Needed at open centre and internal leakage control valve. Duo to the open centre, the oil can’t be blocked and the scraper can’t stay in one position. The pilot operating non return valve, takes over this function by blocking the oil flow, allowing the scraper to stay in one position.
Another possibility is a throttling to control the speed of pivoting. This gives you more control when hydraulically slewing the scraper.
