My server is currently suffering from some problems due to visitors lag and i think the best solution for it, is to restart apache every 2/3 hours or so
How can i do this through cronjob ?

Why do you want to do this?If you are experiencing a specific problem with Apache.It Will definitely be more beneficial for you to have a look into the access/error logs, and make adjustments accordingly.Give us some more information and we can look into your logs and give you a more appropriate solution.
None the less heres the cron to restart apache.
0 */3 * * */ root/restart_apache > /dev/null 2>&1
/etc/init.d/httpd restart

I can almost guarantee this 'fix' will not address your real issue. Why not post your Http.conf settings and a little info on your server resources (memory, cpus) and we might help fix your config issues.

Instead of adding to the crontab of an individual user (root), I would add hacks like this to /etc/cron.d.
Change 'apache2' to whatever the init script is on debian.
echo '* */3 * * * root /etc/init.d/apache2 restart 2>&1 >/dev/null' > /etc/cron.d/apachesux
