Description

一种割草机 技术领域
本发明涉及园林设施技术领域，特别涉及一种割草机。
 背景技术
割草机是用于户外草坪、花园、运动场草地等的草地维护保养的常用工具。在割草机底部设置有切割腔室，割草机底部前侧设置有多个与切割腔室相通的第一进草通道，在切割腔室中部转动连接有沿着水平面旋转的刀片，刀片在离地的一定高度位置上旋转，从而将过长的草切割掉，使得草地外观平整美观。
但是在刀片旋转切割草的过程中，草自身的抗弯能力很难与刀片的切割力相平衡，此时在刀片切割速度较低时，草在切割过程中被推倒或撕裂；而刀片切割速度越高，静止的草在瞬间获得刀片所传递的速度并立即产生很大的加速度以及与其方向相反的惯性力，刀片切割速度越高则惯性力越大，因而草的总抗弯能力也就越大，有利于草的顺利切割。
因此在割草机使用过程中存在如下问题：（1）在刀片切割速度较低时，在草切割过程中容易被推倒而导致没有切割掉的问题，草在切割过程中容易被撕裂而导致切割不平整的问题；（2）虽然随着刀片的切割速度逐渐提高能够逐渐解决草在切割过程中被推倒或撕裂的问题，但是在刀片高速运作时，切割过程中的能耗急剧升高。
 技术解决方案
本发明的目的是提供一种割草机，通过对切割过程中的草进行支承，以提高草的总抗弯能力，从而实现刀片在较低的切割速度下实现对草的顺利切割，减少切割过程中所需能耗。
本发明的上述技术目的是通过以下技术方案得以实现的：一种割草机，包括割草机本体，所述割草机本体底部设置有切割腔室，所述切割腔室中部转动连接有刀片，所述割草机本体底部的前侧设置有多个与切割腔室相通的第一进草通道，多个所述第一进草通道上设置有用于提高草在切割过程中的总抗弯能力的支承机构，所述支承机构包括可拆卸在多个第一进草通道上的底座、多个并排设置在底座上且延伸至切割腔室下方的支承片，所述底座上设置有多个分别与多个第一进草通道相通的第二进草通道，所述刀片旋转范围的正投影与多个支承片的正投影相重叠。
通过采用上述技术方案，在割草机本体行进过程中，待切割的草从第一进草通道、支承机构的底座的第二进草通道进入到多个支承片之间，且待切割的草的顶部穿出支承片，此时在通过刀片切割时，处于两个支承片之间数量众多的草互相支承，且支承片也能够对草进行支承，从而提高草的总抗弯能力，实现刀片在较低的切割速度下实现对草的顺利切割，减少草在切割过程中被推倒或撕裂的情况发生，且减少切割过程中所需能耗。
本发明的进一步设置为：多个所述支承片朝向切割腔室延伸的长度不同，多个所述支承片靠近切割腔室一端的端点连线呈以圆心处于刀片旋转中心线上的圆弧形。
通过采用上述技术方案，此时在刀片旋转一圈对草切割时，沿着割草机本体的前进方向（也可以说是第一进草通道的延伸方向），处于任意相邻的两个支承片之间的草所被切割的长度相同，以实现稳定的对草进行切割。
本发明的进一步设置为：沿着所述第一进草通道的延伸方向，所述刀片旋转范围的正投影与多个支承片的正投影重合的长度不小于割草机本体每秒行进距离为S米与刀片每秒转n圈的比值。
通过采用上述方案，在沿着第一进草通道的延伸方向中，切割片每转一圈所切割的草的长度为割草机本体每秒行进距离为S米与刀片每秒转n圈的比值，此时使得刀片旋转范围的正投影与多个支承片的正投影重合的长度不小于割草机本体每秒行进距离为S米与刀片每秒转n圈的比值，能保证支承片对草进行支承，以保证一直提高草的总抗弯能力的状态，以实现刀片在较低的切割速度下实现对草的顺利切割。
本发明的进一步设置为：沿着所述第一进草通道的延伸方向，所述刀片旋转范围的正投影与多个支承片的正投影重合的长度为10-30毫米。
通过采用上述技术方案，在割草机本体的实际使用时，割草机本体每秒行进距离为通常0.6-0.8米，刀片每分钟转速通常为3000-4000圈，此时在割草机本体每秒行进距离为0.6米，刀片每分钟转速为4000圈时，割草机本体每秒行进距离为S米与刀片每秒转n圈的比值最小，且比值为9毫米；通过使得刀片旋转范围的正投影与多个支承片的正投影重合的长度为10-30毫米，从而能够保证在实际使用过程中，支承片对草的支承效果，以保证草在被切割过程中的总抗弯能力。
本发明的进一步设置为：所述支承片的厚度为4-6毫米，相邻的两个所述支承片之间的间距为30-40毫米。
通过采用上述技术方案，支承片的厚度为4-6毫米，同时相邻的两个支承片之间的间距为30-40毫米，此时支承片的厚度较薄，相邻的支承片的之间的间距较大，此时能减少对草沿着第一进草通道、第二进草通道进入到切割腔室内的影响。
本发明的进一步设置为：所述支承片的高度为10-15毫米。
通过采用上述技术方案，支承片的高度为10-15毫米，此时能提高对草的支承长度，以提高草的总抗弯能力。
本发明的进一步设置为：所述支承片上表面到刀片之间的间距为4-6毫米。
通过采用上述技术方案，支承片上表面到刀片之间的间距为4-6毫米，此时在通过支承片对草支承时，刀片与支承片上表面距离较短，从而保证草处在刀片切割所在高度的总抗弯能力。
本发明的进一步设置为：所述底座通过多个螺栓固定连接在多个第一进草通道上。
通过采用上述技术方案，底座通过多个螺栓固定连接在多个第一进草通道内，从而便于拆装更换。

 本发明的最佳实施方式
以下结合附图对本发明作进一步详细说明。
实施例：一种割草机，包括割草机本体1，割草机本体1底部设置有切割腔室11，切割腔室11中部转动连接有刀片12，割草机本体1底部的前侧设置有多个与切割腔室11相通的第一进草通道13。
多个第一进草通道13上设置有用于提高草在切割过程中的总抗弯能力的支承机构2，支承机构2包括可拆卸在多个第一进草通道13上的底座21、多个并排设置在底座21上且延伸至切割腔室11下方的支承片22，底座21上设置有多个分别与多个第一进草通道13相通的第二进草通道211，底座21通过多个螺栓3固定连接在多个第一进草通道13上，螺栓3安装在第二进草通道211和第一进草通道13处。
刀片12旋转范围的正投影与多个支承片22的正投影相重叠。多个支承片22朝向切割腔室11延伸的长度不同，多个支承片22靠近切割腔室11一端的端点连线呈以圆心处于刀片12旋转中心线上的圆弧形。沿着第一进草通道13的延伸方向，刀片12旋转范围的正投影与多个支承片22的正投影重合的长度（图中标注为L1）不小于割草机本体1每秒行进距离为S米与刀片12每秒转n圈的比值。沿着第一进草通道13的延伸方向，刀片12旋转范围的正投影与多个支承片22的正投影重合的长度（L1）为10-30毫米。在割草机本体1的实际使用时，割草机本体1每秒行进距离为通常0.6-0.8米，刀片12每分钟转速通常为3000-4000圈，此时在割草机本体1每秒行进距离为0.6米，刀片12每分钟转速为4000圈时，割草机本体1每秒行进距离为S米与刀片12每秒转n圈的比值最小，且比值为9毫米；因此使得刀片12旋转范围的正投影与多个支承片22的正投影重合的长度L1为10-30毫米。
支承片22的厚度（图中标注为L2）为4-6毫米，相邻的两个支承片22之间的间距（图中标注为L3）为30-40毫米，此时支承片22的厚度较薄，相邻的支承片22的之间的间距较大，此时能减少对草沿着第一进草通道13、第二进草通道211进入到切割腔室11内的影响。支承片22的高度（图中标注为H1）为10-15毫米，此时能提高对草的支承长度，以提高草的总抗弯能力；支承片22上表面到刀片12之间的间距（图中标注为H2）为4-6毫米，此时在通过支承片22对草支承时，刀片12与支承片22上表面距离较短，从而保证草处在刀片12切割所在高度的总抗弯能力。
实施效果：在割草机本体行进过程中，待切割的草从第一进草通道、支承机构的底座的第二进草通道进入到多个支承片之间，且待切割的草的顶部穿出支承片，此时在通过刀片切割时，处于两个支承片之间数量众多的草互相支承，且支承片也能够对草进行支承，从而提高草的总抗弯能力，实现刀片在较低的切割速度下实现对草的顺利切割，减少草在切割过程中被推倒或撕裂的情况发生，且减少切割过程中所需能耗。
本具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
