Description

Flex scraper

The flex scraper is a very animal-friendly manure scraper that is sometimes compared to the JOZ folding scraper. However, unlike the folding scraper which folds completely, the flex scraper only folds partially. The flex scraper needs just 1.5 metres to unfold its scraper arms again, so it only misses a small area of floor.

JOZ supplies two types of flex scrapers; the standard flex scraper and the flex scraper with E-rubber.

The flex scraper is fitted with a 4 cm wear-resistant rubber along the entire underside, making it very maintenance-friendly. The entire frame is at the top of the scraper, so there is no contact between the metal and the floor. The narrow main frame allows the scraper to open quickly, and both arms fold double during its return pass. This means that during the return pass it is possible to drive over the flex scraper, and cows can pass the scraper without having to negotiate obstacles.

The flex scraper has a bend in the main frame as standard, which prevents manure and bedding from ending up in the stalls. The manure and bedding slide towards the middle of the scraper, so the flex scraper glides more evenly and easily.

Flex scraper with E-rubber

JOZ introduced the flex scraper with E-rubber in 2020. Just like a standard flex scraper, a flex scraper with E-rubber has rubber along its entire underside, the difference being that E-rubber is used. This type of rubber was specially developed for sand barns and barns with more demanding conditions. The E-rubber can also be mounted on existing systems.

The flex scraper with E-rubber is very animal-friendly, and can be used on asphalt floors and hard-to-reach places, such as under a slatted floor. Furthermore, this new flex scraper has the same features as the standard flex scraper.

Other manure scrapers

Is the flex scraper not suitable for you after all? Then take a look at the combi scraper, multi-scraper, slatted floor scraper or delta scraper. Learn more about the differences in our blog ‘How does a manure disposal system work?’.

Characteristics of the Flex Scraper

• Overdriveable
• Easy to maintain
• Equal or unequal alley length with chain
• Suitable for flat floors and UNP guides
• Reinforced galvanised frame on top of the scraper
• Folds open quickly, faster than a folding scraper
• Animal-friendly and resilient structure
• Perfect for sand barns
• Suitable for chain, cable or rope drives
• Suitable for barns with straw bedding

Suitable for various types of floors

The flex scraper is suitable for alleys of 135 to 400 cm in width, and perfect for barns with the following floors:

• Solid concrete floors
• Flat floors
• Low-emission floors
• Asphalt floors (only flex scraper with E-rubber)

The type of floor affects how easily animals can walk, in other words, the level of animal comfort and stress in the barn. Environmental requirements and legislation limit a farmer’s freedom in choosing the type of floor. Fortunately, JOZ has a suitable and proven manure scraper system for every combination of floor type, stall bedding and animal.

Drive units

JOZ manure scrapers are propelled by rope, galvanised steel cables, a stainless steel cable, or a steel chain. JOZ uses 3 different types of drive stations:

• Drum drive (rope & cable)
• Chain drive (chain)
• Cable drive (cable)

The type of drive station depends on the type of floor and the length of the manure alley.

Drum drive

The JOZ drum drive can be used on slatted floors, solid concrete floors, rubber floors and low-emission floors. The drum drive consists of a narrow, large-diameter drum that can be used in combination with rope, a plasticised cable or a stainless steel cable. A scraper system always requires two drive stations. One station winds the rope, while the other station unwinds it at the same time, so the system does not have to be under tension.

The drum drive is available in a floor-mounted version (beyond the reach of the cows) or on a console which is installed inside or outside the barn. The drive is ideal for barns with long alleys and very intensive use.

Chain drive

JOZ chain installations are equipped with one drive station per system. One chain installation is suitable for one or two manure alleys, and depending on the situation, one or more scrapers can be used per alley. The chain drive can be used on a solid floor, slatted floor, rubber floor, or low-emission floor.

The motor gear units are directly driven, without belts. The drive is placed on a vertical console with protective caps. We recommend using a fully automatic hydraulic tensioner for the best scraping results. This keeps the system correctly tensioned at all times, which means less wear and tear. Moreover, you will never be too late with tensioning.

Cable drive mechanism

In addition to the drum drive mechanism (rope/cable) and the chain drive mechanism, JOZ also supplies a cable scraping system which is propelled by a galvanised steel cable. The cable installation is equipped with one drive station per system, which pulls the cable back and forth. The system is driven by a drive roller.

This drive can only be used with a slatted floor.

Correct tensioning

We recommend using a fully automatic hydraulic tensioner. This keeps the system correctly tensioned at all times, which in turn means less wear and tear. Moreover, you will never be too late with tensioning.

Easy to use

The drives are easily controlled with JOZ’s MSC control box. What makes this control box so special is that it communicates with a precision sensor on the drive motor. As a result, the control cabinet always knows the position of the manure scraper in the alley.

Various settings are possible. We can set up manure scrapers exactly according to your preferences. The system can even be fitted with frost protection and remote control.

Characteristics of the MSC control box

• Easy operation
• Unique cow protection
• Can be used with all JOZ drive stations
