目前,室外体育场划线的主要器材是灰壶和漏灰器,使用时费工、费力、工效低。用灰壶划线粗细不匀,漏灰器装灰费工,线也不容易划直,我们试制的划线车,经过五年的使用,效果良好,现介绍如下: 一、用料: 1.薄扳—2mm (0.75mx0.24m) 2.焊管 (φ20mm 2.45m,φ15mm 0.20m) 3.铁皮—0.5mm (2.40mx0.22m) 4.钢筋 (φ12mm 0.45m φ6mm 0.45m) 5.铁丝网 (4目 0.3m×0.15m) 6.橡胶轮 (φ200mm 2个) 二、制作: 1.用铁皮制成0.5m×0.2m×0.2m的灰箱,灰箱底留0.3m×0.05m的漏灰口.灰口侧打8个螺拴眼(如图—1)。将铁丝网装在箱底(如图—2)。 2.用薄板制成0.5m×0.05m×0.0 5mU型车座
At present, the main equipment for marking the outdoor stadiums is the gray pot and the ashtray, which is laborious, laborious and inefficient when used. Wiping the uneven thickness with a gray pot, ashtray ash and waste equipment, the line is not easy to straight, we trial of the crossed car, after five years of use, the effect is good, are as follows: First, the material: 1 . Thin pull -2mm (0.75mx0.24m) 2. Welded pipe (φ20mm 2.45m, φ15mm 0.20m) 3. Sheet metal -0.5mm (2.40mx0.22m) 4. Steel bar (φ12mm 0.45m φ6mm 0.45m) 5. Barbed wire 4 head 0.3m × 0.15m) 6. Rubber wheel (φ200mm 2) Second, the production: 1. Made of 0.5m × 0.2m × 0.2m of the gray box, leaving the bottom ash box 0.3m × 0.05m of the lime Mouth. Gray mouth to play eight bolt eye bolt (Figure -1). The barbed wire installed in the bottom (Figure -2). 2. Made of sheet 0.5m × 0.05m × 0.0 5mU type seat
