Abstract
The utility model relates to a cutter head for a primary crusher, which is a cutter head mainly applied to rubber and plastic primary crushers. The cutter head is mainly characterized in that the cutter head is in a combination type, and comprises a cutter head body, a cutter blade and a fastening screw; after a cutter is blunt or damaged, the whole cutter head is unnecessarily dismounted and only the cutter blade is dismounted and replaced. The utility model solves the defects in the prior art that the cutter head for a primary machine has high fabrication cost and inconvenient installation and dismounting.
Description
Technical field
The utility model relates to a kind of boulder crusher cutterhead, particularly a kind of rubber and plastics boulder crusher cutterhead of being applied to.
Background technology
The cutterhead of rubber that is using in the prior art and plastics boulder crusher is monoblock type or two kinds of forms of built-up welding, as shown in Figure 5 and Figure 6.When normal wear or the damage of unexpected tipping in use appearred in monoblock type, whole cutterhead all will be scrapped, and the price of a cutterhead is wanted 3000～5000 yuan, and whole boulder crusher contains 20 cutterheads, and the cutterhead price of entire machine needs 6～100,000 yuan so; And about an about 80kg of monoblock type cutterhead weight, change very inconvenient, time-consuming.And for built-up welding formula cutterhead, though its manufacturing cost reduced, yet in case when cutter occurring and crumbling with blunt or cutter, replacing is got up equally very inconvenient, time-consuming.
Summary of the invention
The boulder crusher cutterhead of easy installation and removal when the purpose of this utility model provides a kind of low cost of manufacture, cutterhead with blunt or damage.
The technical scheme that its technical problem that solves the utility model adopts is: cutterhead is a combined type, is made up of cutterhead main body, blade, fastening bolt.The symmetrical up and down butt joint of two types that is shaped as of cutterhead main body forms; Blade is that a full circle ring plate is fastened on the cutterhead main body with screw, or the synthetic circular ring plate of several set of blades, is fastened on the cutterhead main body with screw.In order further to strengthen the serviceability of blade, all there is the location fastener hole on the blade two sides, the two-sided use of energy, and promptly sharpening once can use twice.
The utility model beneficial effect is: owing to adopted such scheme, cutterhead to be divided into cutterhead main body and two parts of blade, so cutterhead is during with blunt or tipping, only need to change the blade on the cutterhead main body, the cutterhead main body can must be used for a long time, need not dismounting and change, saving of work and time.And the cost of manufacture of the blade of a boulder crusher is in the prior art---about 1/5 of solid cutter, the cutterhead expense of having saved boulder crusher greatly is so its beneficial effect is very obvious.
