Technical field

The utility model is related to cutter manufacture field more particularly to a kind of crusher cutters.

Background technology

Currently, some old and useless articles are all then to be transported at tiny particle by crusher in crushing in recycling It is reprocessed into extensive stock to product processing factory, the critical piece that fragmentation is played in crusher is crushing cutter, existing Cutter is mainly breathed out the discoidal blade of several groups that interval string is located on knife stick by knife stick and is formed, and the blade of blade is using process In it is easy to wear or encounter the object bigger than rigidity and damage, influence crusher when blade is damaged or worn out and be normally crushed It needs to replace entire blade when effect, replacement cost is high, and often has multiple blades on a blade, when a knife Wearing or damaging to the whole waste for can also cause with changing resource occur in sword.

Utility model content

The purpose of the utility model is to overcome problem above of the existing technology, provide a kind of crusher cutter, drop Low blade is with changing this into, reducing the wasting of resources.

To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions：

A kind of crusher cutter, including a knife stick, several cutterheads being sleeved on knife stick, two be screwed onto knife stick respectively The round nut at both ends, a clamping disk, the front of the cutterhead set that there are four the blades being located on square four vertex Slot installs a blade in each insert groove, and the both ends of the blade are respectively provided with a blade and two blades are located at knife The same side of piece, one of blade is located at outside insert groove blade when being mounted in insert groove, another blade is close to cutterhead Center, the clamping disk are mounted on knife stick and between cutterhead front and round nuts.

Wherein, it sets there are one circular pin hole, is located on the cutterhead in insert groove there are one setting in the middle part of the blade With the matched straight pin of pin hole, straight pin is just inserted into pin hole when the blade is mounted in insert groove.

Wherein, the middle part of the knife stick is eight prisms, and the both ends of the knife stick are each to have one section of spiro union portion and one section of cylinder by oneself The interconnecting piece of body, the spiro union portion cutterhead and are clamped and are each provided with one and eight in the middle part of disk close to the both ends of eight prisms The matched mounting hole of prism.

Wherein, the cross section at middle part and the cross section of mounting hole of the knife stick are octagon.

Wherein, the depth of the cutterhead upper slitter dish groove is equal to the half of cutterhead thickness.

Wherein, the thickness of the blade is equal to the half of cutterhead thickness.

Wherein, the thickness for clamping disk is equal to the half of cutterhead thickness.

Wherein, the cross section of the blade is crescent.

Wherein, the shape of the insert groove and the shape of blade match, but there are one in the side of close cutter head center The notch of section edge length same widths, making the side wall of blade and insert groove, there are gaps.

The utility model has the beneficial effects that：Blade with blade is mounted in the insert groove on cutterhead, when When a blade on one blade is damaged or worn out, the blade exchange direction that will be damaged or worn out by dismantling cutter, The blade for keeping another intact is located at outside insert groove, when two upper blades of a blade are all damaged or worn out, leads to It crosses and dismantles cutter and fall the blade exchange being damaged or worn out, which can reduce the cost of blade exchange and maintenance, reduce more Wasting of resources when allowing blade replacement.

Specific implementation mode

Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in detail.

Embodiment as shown in Figures 1 to 6, a kind of crusher cutter, including a knife stick, several be sleeved on the knife on knife stick Disk, two be screwed onto the round nut at knife stick both ends, a clamping disk respectively, the front of the cutterhead sets that there are four be located at just Insert groove on rectangular four vertex installs a blade in each insert groove, and the both ends of the blade are respectively provided with a knife Sword and two blades are located at the same side of blade, and one of blade is located at insert groove when blade is in insert groove Outside, another blade is close to cutter head center position, the clamping disk be mounted on knife stick and positioned at cutterhead front and round nut it Between.

Blade with blade is mounted in the insert groove on cutterhead, when a blade on a blade occurs When being damaged or worn out, the blade exchange direction that will be damaged or worn out by dismantling cutter, the blade for keeping another intact is located at knife Outside film trap, when two upper blades of a blade are all damaged or worn out, it will be damaged or worn out by dismantling cutter Blade exchange falls, which can reduce the cost of blade exchange and maintenance, reduces wasting of resources when more allowing blade replacement.

It is set in the middle part of blade there are one circular pin hole, is located on cutterhead in insert groove and sets that there are one matched with pin hole Straight pin, straight pin is just inserted into pin hole when blade is mounted in insert groove.

Stability of the blade in insert groove is improved by the way that pin hole and straight pin is arranged, blade is avoided to be shaken in insert groove It shakes.

The middle part of knife stick is eight prisms, each interconnecting piece for having one section of spiro union portion and one section of cylinder by oneself in the both ends of knife stick, Middle spiro union portion is used to screw togather cutterhead with round nut and clamp disk locking, interconnecting piece for connecting drive with the driving device of crusher Moving knife stick rotates, and spiro union portion cutterhead and is clamped and is each provided with one and the matching of eight prisms in the middle part of disk close to the both ends of eight prisms The mounting hole of conjunction.

The cross section at the middle part of knife stick and the cross section of mounting hole are octagon, convenient for when installing cutterhead, making phase Blade on two adjacent cutterheads is staggered 45° angle.

The depth of cutterhead upper slitter dish groove is equal to the half of cutterhead thickness；The thickness of blade is equal to the half of cutterhead thickness；Folder The thickness of tight disk is equal to the half of cutterhead thickness.Make to be engaged to form shear structure closely between two groups of cutters, while convenient for dress Match and the replacement of each component.

The cross section of blade be crescent, it is simple in structure, convenient for manufacture.The shape phase of the shape of insert groove and blade Match, but in the side of close cutter head center, there are the notches of one section of edge length same widths, make the side wall of blade and insert groove There are gap, prevent the side wall of blade and insert groove from colliding two damage blades.

Basic principles, main features, and advantages of the present invention has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.
