Escampadora de fems

Una escampadora de fems moderna

Una escampadora de fems és una màquina agrícola que es fa servir per distribuir fems sobre un camp com a fertilitzant del sòl. Una escampadora de fems moderna consisteix en un remolc que va darrere del tractor amb un mecanisme rotatori dirigit per la presa de força del tractor. A Amèrica del nord també són comuns els escampadors de fems muntats en un camió.

Operació

Els primers escampadors de fems eren moguts per cavalls o grups de cavalls. Actualment hi ha també petites escampadores de fems que es poden accionar per un tractor de jardineria o per un vehicle tot terreny. Recentment també s'han desenvolupat noves versions d'escampadores, per exemple, accionades hidràulicament.

Història

La primera escampadora automàtica plenament operativa va ser dissenyada per Joseph Kemp l'any 1875 qui va fundar l'empresa J.S. Kemp Manufacturing Co. a l'estat de Nova York als Estats Units. El 1906 va vendre el seu disseny a l'empresa International Harvester^[1][2][3]

Joseph Oppenheim de Maria Stein, Ohio va ser l'inventor del sistema d'estendre els fems àmpliament (widespreading manure spreader)^[4]

Oppenheim, era un mestre d'escola en un poble i el preocupave que els nois de l'escola sovint deixaven d'assitir a classe perquè feien la feina d'escampar i carregar fems manualment,^[5] i per això, inventà aquest sistema d'escampar fems automàticament.^[6] El 18 d'octubre de 1899, Oppenheim començà a produir la maquinària amb el seu sistema que va anomenar comercialment "New Idea".^[7]
