Motor Applications in Automatic Manure Scrapers

1. Component Overview

Automatic manure scrapers are widely used in pig, cattle, and poultry farms to maintain cleanliness and reduce disease risk. The key components include:

Drive System: Includes high-torque motors, precision gear reducers, chains or wire ropes. It provides the power needed to move the scraper stably over long durations.

Scraper Assembly: T-shaped or flat boards made from wear-resistant alloy or composites, pulled by chains or ropes to remove manure across barn aisles. Some support multi-zone synchronous scraping.

Guidance and Turning Units: Include corner wheels, guiding tracks, and tensioners that ensure directional stability and scraping precision.

Control System: Based on PLC or microcontroller, with timers, limit switches, position sensors, and overload protection for automation, reversing, and safety features.

Power Supply: Typically uses AC220V or DC24V; remote barns may use solar or backup batteries for reliability and flexibility.

Safety & Monitoring: Emergency stop buttons, guards, overload alarms, and wireless remote controls enhance operator safety and management ease.

2. Working Principle

The system starts scraping based on timers or remote commands. The control unit activates the motor, which drives the chain or rope through a reducer, pulling the scraper slowly along the barn floor to push manure into a pit or trench.

Once the scraper reaches the end, limit switches or position sensors trigger the motor to stop or reverse. Some models detect obstructions or load changes, automatically stopping and issuing alerts to prevent damage.

The operation requires no manual intervention, adapting frequency and timing to actual manure levels. This ensures consistent cleaning and improves livestock facility hygiene automation.

3. Role of Motors

Motors are essential in providing stable power and smart control within manure scrapers. Their roles include:

Stable Power Delivery: Motors must provide consistent high torque at low speeds to ensure smooth scraper movement under varying loads.

Corrosion & Sealing: Motors operate in high-moisture, ammonia-rich environments and require IP65+ protection, sealed bearings, and corrosion-resistant housings.

Responsive & Efficient: Hall sensors or encoders enable closed-loop control for accurate speed and positioning. Soft-start/stop reduces mechanical wear and noise.

Compact & Serviceable: Motors must be compact for trench or ground mounting and easy to maintain or replace.

Overload Protection: Motors must handle sudden load changes due to blockages, with built-in overcurrent and thermal safeguards for safe operation.

4. Custom Motor Solutions

We offer specialized corrosion-proof motor systems designed for manure scrapers operating in harsh farm conditions. The GPG-DC90 waterproof BLDC motor with planetary reducer delivers up to 60Nm torque, suitable for mid- to large-scale machines.

It features IP67-rated sealing, corrosion-resistant aluminum housing, and integrated Hall sensors for closed-loop operation. Supports soft start and remote control for flexible scheduling and improved stability.

We also provide custom solutions tailored to scraper layouts (U-grooves, flat floor, multi-channel sync). Options include custom flange mounts, reducer ratios, and motor speed. Motor-controller integration supports wireless monitoring and diagnostics for smart livestock automation goals—saving labor, improving efficiency, and reducing costs.
