Dedicated wire brush for snow removal truck, as well as production equipment and production method of dedicated wire brush

Abstract

The invention discloses a dedicated wire brush for a snow removal truck, which is high in toughness, good in clean-keeping effect and low in using cost. The dedicated wire brush comprises 90 weight percent of pp and 10 weight percent of a drawing agent. The dedicated wire brush structurally comprises a body and three flanges evenly distributed on the outer surface of the body, and the ratio of the diameter of an excircle formed through the farthest points of the three flanges to the diameter of the inner circle formed through the nearest points of the three flanges, fai 1 to fai 2 equals to 2 to 1. The invention further provides production equipment for the dedicated wire brush for the snow removal truck. The production equipment comprises an extruder, and further comprises a first cooling water tank, a drying oven, a second cooling water tank, a stretchable dragger, a shaping dragger and a second cooling water tank, the inner edge of the die head of the extruder is formed through three circles in pairwise tangency, and the ratio of the largest outer diameter to the largest inner diameter of the inner edge of the die head, fai 1 to fai 2 equals to 2 to 1. The invention further provides a using method of the equipment.

Description

technical field [0001] The invention relates to environmental cleaning appliances, in particular to a special brush filament for snow plows. The invention also provides production equipment and a production and use method for the brush filament. Background technique [0002] In middle and high latitude regions, snowplows can quickly and efficiently remove snow on the ground, and are an efficient environmental cleaning tool. When the snow sweeper is working, the brush roller rotates to drive the brush filaments to clean the ground. As the vulnerable and consumable parts of the snow sweeper, the strength and toughness of the brush filaments directly determine the cleaning effect and use cost. The existing snow sweeper The cross-section of special brush filaments is generally circular or rectangular, with low toughness and easy to break during use, which increases the cost of use and affects the cleaning effect. Contents of the invention [0003] The technical problem to be ...
