Description

热焊接系统和方法
【发明目的】
本发明涉及用于塑料织物或覆盖物的热焊接系统，塑料织物或覆盖物尤其是应用于农业部门，并且更具体地应用于那些农田，这些农田在经历熏烟消毒处理后通过塑料覆盖物而被密封，以便消灭寄生动物、真菌及细菌，进而寻求将后续田地耕种优化到最大程度的趋势。
更具体地，所述热焊接系统主要由热焊接装置组成，该装置集成到由农业机械或车辆拉动的结构内，所述农业机械或车辆的类型为：其结合有成卷的密封装置，用于借助聚合覆盖物将地面密封起来，所述聚合覆盖物铺设在田地上，并且允许将气体或熏蒸物质限制在该聚合膜与田地的用于土壤消毒的部位之间，从而使得田地的该部位被密封，并且阻止了熏蒸物质的传播，进而允许延长其在田地上的施加阶段，增加了其效能，并且阻止了物质向外泄露，这样当农业车辆工作时并且在其行进方向上，减小或避免了环境污染。
【发明背景】
当前，农业部门中其中一个令人讨厌的难题是：覆盖一块田地时出现的低效率，该块田地被熏烟消毒处理，并且覆盖物如上文提及的覆盖物覆盖该块田地，由于现有的车辆没有集成允许对相邻覆盖物的纵向边缘进行可靠密封的热焊接装置，因此具有熏蒸物质泄漏到环境中的危险。
属于相同申请人的专利申请文献ES2008798(A6)描述了铺设上述类型的覆盖物的当前技术，其由解开的覆盖物及车辆组成。所述车辆没有包括热焊接装置，因此引起了上述问题。
在一些其它情况下，用于将覆盖物解开的系统与设置在车辆内的机械化的粘结装置配合，但是该粘结装置涉及胶水等，由于田地的不规则性及突出，覆盖物在多个点位剥落，进而增加了环境污染的危险，并且进而不得不让大量操作员最终手工介入来解决胶水不足的问题，因而招致运行成本增加，而不会提供有效且集成的系统。
因此，根据上文的描述，现有技术中目前已知的发明执行本发明目的中的功能，但是以不太可靠及不太全面的方式执行，因为其除了具有密封不足可能引起的环境污染、需要采用执行粘结的非自然位置引起的操作员健康受到危害、增加了执行目标操作的时间及需要执行需要严格监管的相当不可靠的人工劳动所引起的成本增加的缺陷外，还无法在单个步骤中执行在一块田地上铺设和密封或解开覆盖物的功能。
【发明描述】
本发明涉及热焊接系统，其克服了上述缺陷，由于其具有由框架或底架组成的结构，该框架或底架可以连接到牵引车辆比如农业车辆或拖拉机上，从而当将熏蒸物质施加于地面并且随着车辆的移动而将覆盖物展开、从卷轴上解开并且逐渐放置在该田地时，其允许执行对叠加在已经放置上去的另一个侧边上的覆盖物的其中一个侧边进行密封，以便借助热焊接而进行密封，而放置在田地上但未与已经放置的覆盖物的任何其他部位接触的其他侧边则逐渐安置在田地内，这样就方便叠加将要放置的覆盖物的下一个部位的另一个侧边，因此提供了开展整个活动的能力：准备用于消毒的田地、当牵引车辆运行时在单个步骤中展开及密封覆盖物，而不需要操作员额外的动作来执行乏味的手工劳动，因此大大减小了运行时间、运行成本、剥落危险，增加了所追求效果的持久性，并且减小或完全避免了环境污染。
特别地，系统优选地包括：用于分配覆盖物的分配器，其允许在相邻覆盖物之间重叠放置覆盖物；及至少一个具有连接装置的结构，该连接装置允许将该结构连接到牵引车辆，所述结构包括至少一个允许将相邻的覆盖物的重叠纵向边缘互相粘结起来的热焊接装置及连接装置，该连接装置允许将该焊接装置连接到该装置。
可以构思出具有两个热焊接装置的热焊接系统的可能性，在此，第一热焊接装置位于结构的第一外部内，第二热焊接装置则位于结构的第二外部内，从而允许借助其中一个侧边进行热焊接，而结构的另一个侧边则放置覆盖物上将与相接的覆盖物的另一个侧边重叠的侧边。
可以构思出的热焊接装置的一种可能性是：每个装置包括：至少一个加热元件，该加热元件对来自风扇的空气加热，并且对热气流加热、施加或分布到重叠部位；滚动装置，其适于在重叠的覆盖物的纵向边缘或侧边上滚动；及借以让来自风扇的空气流通的空气传导装置。
