Basic information
The effectiveness of a manure scraper system for reducing the risk of chicken’s exposure to hydrogen sulfide (H2S) is carried out by comparing the gas levels in the manure. Scrapers can handle solid or semisolid wastes, the high moisture content of swine manure, along with the additional moisture from waterers, washing operations, and other sources, usually dictates that scraped manure waste from the poultry buildings can be handled as a liquid. The liquid is normally stored in outdoor earthen storages or in above ground or underground tanks. To minimize storage and transport requirements, additional dilution water is usually not added to the scraped manure
Measurements were done over four production cycles; during each 12 week cycle, gas concentrations were measured 4 to 5 times during weeks that conventional manure removal activities were performed in the control room, while the scraper system was operated daily in the scraper room. Daily removal of manure from the scraper room resulted in measured maximum H2S concentrations that were significantly lower (by 90%) compared to the control room
The type of manure removal system had no significant effect on ammonia (NH3) concentration and emission; during each trial, NH3 emission increased in both rooms over the 4 to 5 monitored weeks. The scraper system was also operated in two different modes. These tests revealed that NH3 production was reduced when all the manure was removed from the room compared to leaving the liquid portion on the pit floor surface, although the differences were not significant (p > 0.10)
Product description
The manure scraper system is a means of removing manure and other wastes from poultry buildings for storage or treatment outside the building. Like other methods that allow for frequent waste removal, they reduce odour and gas production within the poultry building from stored wastes and improve the environment
Most cable scrapers have a steel or steel supported blade that scrapes on the cleaning stroke and raises by pivoting on an axis above the floor on the return stroke. Blade heights vary from 5 to 12in, depending upon the expected frequency of cleaning and the length of the gutter
Scraper units designed to operate in an open gutter without slats may use an electric shock device to keep animals clear of the unit, particularly when it passes through pen partition walls where injuries could occur. Open gutter scrapers should be supervised while operated in order to minimize the potential for livestock injury
The manure scraper system is adaptable to gestation, farrowing, nursery and finishing buildings and may be used either under slats or in open gutters. They can be installed in new buildings or incorporated into existing buildings. The wastes can be transported to the storage or treatment area by pumps, other mechanical means, or gravity, and full automation can usually be achieved

Features
1. Scraper systems adapt well to frequent and regular loading of anaerobic digesters for bio-gas production because of a minimal amount of dilution water and because they are operated regularly. Frequent collection of the manure minimizes the loss of readily digestible organic materials necessary for efficient biogas production, although recent studies of scraper systems have indicated high nitrogen losses through ammonia volatilization
2. Frequent collection of wastes by scrapers conserves nitrogen because it brings the wastes quickly to |storage, where relatively little nitrogen is lost, scrapers, particularly chain link type, have been successfully used for scraping manure where chopped bedding such as straw, corn cobs, peanut hulls, or similar material is used on solid floor areas and is allowed to work its way through slats or to open scrapers
3. One drive unit can drive from 1 to 6 scrapers, depending upon the building layout and the manufacturer’s recommendations. Single scrapers are commonly used in modified open-front buildings with partially slotted floors, while multiple units are commonly used for farrowing and nursery areas, as well as in totally slotted finishing buildings
Principles
1. If power is interrupted, standby power might be needed to continue scraping and to prevent excessive manure from accumulating in gutters
2. If excess accumulation does occur, care must be taken to prevent scraper overloading and possible chain or cable breakage when the scraper is started
3. Adding water may help move manure accumulations
4. More frequent scraper operation aids in removing manure before it has time to freeze, but this alternative is not feasible in extremely cold temperatures. Even with warm buildings, perimeter insulation is needed in extreme climates to prevent the manure from freezing along the outside gutter walls
Characteristics and operation
1. Commercial scrapers generally range from 2 to 12ft. wide. When scraping under slats, the required vertical clearance between the gutter floor and the underside of the slats ranges from 7 to 18inch, depending upon the scraper type. Unless access for maintenance is required or additional depth for emergency storage is desired, additional clearance offers little advantage and adds to the construction cost. However, additional clearance may occur in remodeled facilities, is not harmful
2. Construction of concrete gutters for scrapers must be carefully planned and carried out, the surface across the gutter should be uniform and level, and gutter width must not vary to allow for good scraper contact and efficient cleaning. This is especially important for scrapers with rigid metal blades, since rough concrete, like any obstruction, can cause scrapers to shut off, scrapers with floating or rubber-edged blades can handle slight irregularities
3. It is also best to select a specific scraper system before constructing a gutter so that the gutter matches the scraper width and provides adequate vertical clearance. It may be necessary to specially form the gutter to allow for installation of the scraper cable or chain hardware and the cable passages
4. A variety of scraper control and operating alternatives is available. Some systems are manually activated by the operator, with the system continuing to operate until switched off, some complete a full scraping cycle and then turn off automatically
5. Timer controls are available that offer complete automation with great flexibility in operating schedules, although it should be recognized that completely unsupervised operations may be hazardous to livestock when uncovered scrapers are used. Selection of control options is a matter of operator preference, cost, labor availability, and size and complexity of the production facility
6. Reversing type scraper systems are normally equipped with sensor assemblies that automatically reverse the scraper when it reaches the discharge point. In addition, they often include safety components such as automatic shutoff, or they reverse when obstructions are encountered
Precautions
1. Cable and chain drives, pulleys, and idlers can be hazardous if they are not shielded or otherwise protected from access
2. Sealed electrical components should be used in the corrosive atmosphere associated with manure gutters and should be inspected frequently to determine whether any potential safety hazards are developing
3. Automated systems should be disconnected prior to maintenance to prevent injury caused by unexpected scraper operation
4. Operators should use similar precautions with storage units associated with scraper units as with any other liquid manure systems
5. Deaths from asphyxiation or hydrogen sulfide exposure have resulted from operators entering storage tanks or from improperly ventilated, covered storage systems
