Delete all post comments NOT attachment or page comments

I have this function that deletes ALL comments after X days. How can I edit this so that it only applies to posts, not pages or attachment pages?

function md_scheduled_delete_comments() {
$comments = get_comments( array(
'post_type' => 'post',
'date_query' => array(
'before' => '3 days ago',
),
) );

if ( $comments ) {
foreach ( $comments as $comment ) {
wp_delete_comment( $comment, $force_delete = true );    
}
}
}
add_action( 'wp_scheduled_delete', 'md_scheduled_delete_comments' );
// You can test it immediately by adding following line:
// add_action( 'wp_loaded', 'md_scheduled_delete_comments' );
