(EN) The present invention provides a shot blasting device capable of efficiently performing dust collection and ventilation in a spraying chamber by using a dust collector provided with a small-sized and low-cost suction unit. The shot blasting device includes a housing (10), a plurality of processing chambers (13a, 13b) provided inside the housing and capable of accommodating therein the workpieces and capable of selectively moving between the carrying-out position and the ejecting position, an air supply port (19) for introducing external air into the processing chambers, and a discharge port disposed at a position opposed to the air supply port at an interval with a processing chamber arranged at the injection position and communicating linearly with a space in the processing chamber arranged at the ejection position, and being in linear communication with the space in the processing chamber arranged at the ejection position, and under the suction effect of the discharge port, the air flowing from the air supply port to the processing chamber at the ejection position is introduced into the discharge port through the processing chamber arranged at the ejection position.
(ZH) 本发明提供一种能够利用具备小型且低成本的吸引装置的集尘器高效地进行喷射室内的集尘·换气的喷丸装置。根据本发明，提供一种喷丸装置，其中，该喷丸装置包括：机箱(10)；多个处理室(13a、13b)，其设置在机箱内，能够在内部收纳工件，能够在搬入搬出位置和喷射位置之间选择性地移动；供气口(22)，其用于向处理室导入外部空气；以及排气口，其设置在隔着配置在喷射位置的处理室与供气口相对的位置，与配置在喷射位置的处理室内的空间直线地连通，在来自排气口的吸引的作用下，从供气口流入到处于喷射位置的处理室中的空气通过配置在喷射位置的处理室被导入到排气口。
