Flushing type sandbox and sand unloading method thereof
The invention discloses a flushing type sandbox. The flushing type sandbox comprises an inner cylinder and an outer cylinder with an open upper end, two opposite sand outlet holes are formed in the side wall of the bottom of the outer cylinder, opening and closing devices used for covering the sand outlet holes are detachably arranged on the two sand outlet holes, the lower end of the inner cylinder is used for being inserted into the outer cylinder, a limiting plate with the diameter larger than that of the outer cylinder is arranged at the upper end of the inner cylinder, and the inner cylinder is filled with a filling core flush with the lower end of the inner cylinder. The two opposite sand outlet holes are formed in the bottom of the outer cylinder, so when the sands in the outer cylinder need to be unloaded or the relative height of the inner cylinder and the outer cylinder needs to be adjusted, the opening and closing devices on the two sand outlet holes can be taken down, so that sands can be unloaded from the sandbox by using a flushing method, the situation that the sands cannot be unloaded due to caking and solidification of the sands is avoided, the requirement on the water content of the sands is not sensitive, the requirement on sand performance parameters is low, and local materials are convenient to use. The invention further discloses a sand unloading method for the flushing type sandbox.
本发明公开了一种冲水式沙箱，包括内筒与上端开口的外筒，外筒的底部侧壁设有两个正对的出沙孔，两个出沙孔上均可拆卸的设有用于遮住出沙孔的开闭装置，内筒的下端用于插入外筒，内筒的上端设有直径大于外筒的限位板，内筒内填充有填芯，填芯与内筒的下端齐平。通过在外筒的底部设置两个正对的出沙孔，从而在需要将外筒中的沙子卸出或调整内筒与外筒的相对高度时，可将两个出沙孔上的开闭装置取下，如此，便可使用冲水的方法进行沙箱卸沙，不会发生因沙子结块、凝固而导致无法卸沙的情况，且对沙子的含水量要求不在敏感，对沙子性能参数要求低，方便就地取材。本发明还公开了一种用于上述冲水式沙箱的卸沙方法。
