Sand paving device and automatic sand paving control method
A sand paving device comprises a walking mechanism, a driving mechanism, a guide hopper, a first lifting mechanism, a sand homogenizing rolling shaft, a scraper blade and a control system. A sand outlet is formed in the bottom of the guide hopper; through the first lifting mechanism, the guide hopper is rotatably arranged on the rack of the walking mechanism around a rotating shaft arranged at the bottom of the guide hopper, so that the included angle alpha between the guide hopper and the projection plane of the rack in the horizontal direction is adjusted; the sand uniformizing rolling shaft is arranged at the sand outlet, and when the sand uniformizing device is in a working state, the driving mechanism is started to drive the sand uniformizing rolling shaft to rotate, so that sand in the guide hopper is uniformly dispersed to a base plane P from the sand outlet through the sand uniformizing rolling shaft; the scraping plate is arranged below the guide hopper and is used for determining the laying thickness of the sand layer; and the control system is used for receiving an external instruction to control the driving mechanism and the first lifting mechanism. In the sand laying process, the first lifting mechanism lifts upwards, so that the included angle alpha between the guide hopper and the projection plane of the machine frame in the horizontal direction is increased, and sand discharging is smoother and smoother.
一种铺沙装置，包括行走机构、驱动机构、导料斗、第一举升机构、匀沙滚轴、刮板和控制系统；导料斗底部具有出沙口；通过第一举升机构，使导料斗绕其底部设置的转轴可转动地设置在行走机构的机架上，从而调节导料斗与机架水平方向的投影面之间的夹角α；匀沙滚轴设置在出沙口处，当处于工作状态时，通过启动驱动机构，带动匀沙滚轴转动，以将导料斗内的沙子经由匀沙滚轴从出沙口均匀分散至基面P上；刮板设置在导料斗下方，用于确定沙层铺设的厚度；控制系统用于接收外部指令实现对驱动机构和第一举升机构的控制。在铺沙过程中，所述第一举升机构向上举升，使导料斗与机架水平方向的投影面之间的夹角α增大，实现下沙更加平缓顺畅。
