get excerpt without images

Is there any way to not get the images with get_the_excerpt()? I am using a my_recent_post() function to pull posts onto the home page and I don’t need to have it pull the images within the posts, just some of the text.

Here’s the function that I am using:

function my_recent_post()
 {
  global $post;
  $html = "";
  $my_query = new WP_Query( array(
       'post_type' => 'post',
       'posts_per_page' => 3
  ));

  if( $my_query->have_posts() ) : while( $my_query->have_posts() ) : $my_query->the_post();

       $html .= "<div class='item'><a href="" . get_permalink() . ""><span>" . get_the_date() . "</span></a>" . get_the_post_thumbnail() . "
       " . get_the_excerpt() . "</div> <div class='clear'></div>";

  endwhile; endif;

  return $html;
}
add_shortcode( 'news', 'my_recent_post' );
