  • Coupled may mean that two or more elements are in direct physical contact. However, “coupled” may also mean that two or more elements are not in direct contact with each other, but yet still cooperate or interact with each other.
  • thorny seeds “goathead seeds,” and the like as used herein are meant to include all thorns, thistles, nettles, barbs, briars, seeds, and otherwise unwanted, sharp or pointed objects found on the ground.
  • Thorny seeds are a prevalent ecological threat that often consumes a pristine tract of land. Thorny seeds not only damage yards and fields but can also cause physical pain to humans and animals. There have been many attempts at removing thorny seeds, with many of these attempts having shortcomings. For example, individuals often burn goathead weeds. However, burning weeds does not always destroy the thorny seeds. In fact, many seeds may survive the heat produced by the fire, and because these thorny seeds are not removed from the land, additional goathead weeds may grow.
  • a thorn extractor apparatus described herein assists a user in removing the thorny seeds from their land.
  • the thorn extractor apparatus may comprise a frame with a roller that contacts the ground to pick up and remove thorny seeds that are spread across a tract of land. The thorny seeds are lifted from the roller and deposited into a collection bin via a screen. It will be appreciated that the thorn extractor apparatus allows a user to permanently remove thorny seeds from any tract of land, thereby preventing future weed growth.

  • the roller 104 may be of varying sizes ranging between a small diameter and a large diameter. It will be appreciated that the roller 104 accumulates the thorny seeds from the ground through engagement with the soft outer material 137 on the roller 104, thereafter depositing the thorny seeds into the collection bin 108 via the screen 106.
  • the roller 104 may be a hard, hollow drum fillable with a liquid or a solid to increase a weight of the roller 104, leading to more pressure applied to the ground surface and a higher propensity to retrieve the dispersed thorny seeds.

In other words, as the nut 136 is moved along the bolt 138, the screen beam 128 and the collection bin beam 103 move relative to the movement of the nut 136 and the bolt 138. If the nut 136 allows more of the bolt 138 to be exposed (i.e., extended), then more tension is placed on the screen 106. On the other hand, if less of the bolt 138 is exposed, then less tension is placed on the screen 106.

Abstract

L'invention concerne un appareil extracteur d'épines comprenant un bâti, un rouleau, un tamis qui entoure le rouleau, et un bac de collecte servant à recevoir les graines épineuses. Le bâti comprend des premier et second éléments latéraux, des coupleurs de bâti et une pluralité de poutres horizontales. Le rouleau et le tamis fonctionnent conjointement pour saisir et transporter les graine épineuses vers le bac de collecte à rejeter. L'appareil extracteur d'épines peut comprendre une pluralité de rouleaux accouplés à une pluralité de tamis. L'appareil extracteur d'épines peut également comprendre un aspirateur, une béquille, des poids ajoutés, et un mécanisme d'attelage conçu pour être tiré par un véhicule. Au moins deux bâtis peuvent être accouplés successivement l'un à l'autre pour multiplier le nombre de rouleaux nettoyant le sol de graines épineuses. L'appareil extracteur d'épines, selon certains exemples, peut comprendre un système d'entraînement automatique ou peut être accouplé à un véhicule.
