Field racing natural grassland hand-held marking car

Abstract

The invention discloses a walking line-marking vehicle for field event native pasture and mainly relates to the field of field event equipment. The walking line-marking vehicle comprises a chassis frame for fixing a hopper, wherein a linear wheel rack is arranged on the front side of the chassis frame; a front wheel is mounted at the front end of the linear wheel rack; a transverse bracket is arranged on one side of the linear wheel rack; a marking wheel is arranged at the outer end of the transverse bracket; rear wheels are mounted on two sides of the chassis frame; a blanking channel corresponding to the marking wheel is formed in the bottom of the left side / right side of the hopper; a screen of which the front side is capable of springing is arranged in the blanking channel, and the springing of the screen is linked with the front wheel; a screened product outlet is formed in the rear side of the blanking channel; and a movable trailer used for receiving materials is arranged on the outer side of the screened product outlet. The walking line-marking vehicle disclosed by the invention has the beneficial effects that the line marking efficiency and quality can be obviously improved, the line marking retention degree is obviously improved compared with that in the prior art, the operating difficulty is lowered, and people are able to rapidly draw accurate, elegant, standard and durable race lines with the walking line-marking vehicle.

Description

technical field [0001] The invention relates to the field of track and field equipment, in particular to a hand-held marking vehicle for natural pastures in field competitions. Background technique [0002] Track and field events mainly include field events and track events, and field events include javelin, hammer throw, shot put, discus and other items. Most field events need to draw lines on the field before the competition. With the continuous formalization of sports competitions and the improvement of economic level, most of the domestic competition venues are laid with better quality natural lawns. Since these venues have multiple uses during non-field competitions, they are generally marked with one-time markings, which can disappear with rain, time, and lawn repairs. Among them, in view of environmental protection, turf protection and other reasons, the use of solid powder such as lime powder for marking is a major marking method, and marking vehicles are mainly us...

AI Technical Summary

Problems solved by technology

[0003] First of all, there is a major disadvantage of using solid powder such as lime powder, that is, it is easy to be wiped / kicked

This is mainly because the powder falls on the turf, and the adhesion effect is poorer than that of the paint

Moreover, the existing marking vehicles all adopt the method of automatic blanking during travel, and the powder falls to the grass through the screen by gravity

In order to maintain the continuity of the marking line and the speed of the falling material, the mesh of the screen is relatively large, which results in the fineness of the powder, uneven particles, and unavoidable agglomeration.

As a result, the speed of entering the lower layer of the turf is slow, the adhesion effect is not good, and the agglomerated large particles are splashed around, which seriously affects the marking quality

[0004] Secondly, the accuracy of the lines drawn by the existing marking vehicles is poor, it is difficult to grasp the straight lines and arcs, and the width of the lines is also difficult to adjust, which not only increases the difficulty of operation, but also affects the layout effect of the arena

At the same time, the feeding port of the solid powder marking vehicle is set in the center, which makes people need to be careful to avoid the line just drawn when walking, which is very inconvenient
