Description

A kind of breaker that is used for fodder cutter

The utility model relates to a kind of breaker that is used for fodder cutter, refers in particular to the breaker of the fodder cutter that utilizes moving knife to match with stationary knife to reach broken purpose.

By match with the stationary knife breaker of the fodder cutter that reaches broken purpose of moving knife generally is by moving knife, the knife rest of moving knife is installed, drive the transmission main shaft of moving knife and blade holder turns, with the compositions such as stationary knife that match with moving knife, because at present between the knife rest and transmission main shaft of this class breaker, all be to be connected between moving knife and the knife rest by welding manner, and stationary knife also is directly to be welded on the support, this has just caused moving, the spacing of stationary knife can't be adjusted, can't reface after the blade wearing and tearing, the problem that can't change, and cutter causes transmission main shaft scrapping down to complete machine easily after the damage in installation or use.

For this reason, the purpose of this utility model is to overcome the deficiency of prior art, and provide a kind of moving, stationary knife is replaceable, between the two apart from can adjusting, and can polish after the blade wearing and tearing and reuse removable a kind of breaker that is used for fodder cutter after the tool damage.

The technical scheme that realizes the utility model purpose is a kind of breaker that is used for fodder cutter, comprise moving knife, the knife rest of moving knife is installed, link to each other with knife rest and drive the transmission main shaft of knife rest rotation, and the stationary knife that matches with moving knife, its special character is that the middle part of knife rest is a hollow shaft, hollow shaft sleeve is loaded on the transmission main shaft, the periphery of hollow shaft is provided with the one or more pairs of hold(ing)-down clips parallel with its axis direction, a pair of hold(ing)-down clip is formed by two, in two hold(ing)-down clips one is one or is connected as a single entity with hollow shaft, fuses by dismountable connected mode between two hold(ing)-down clips.

And, moving knife comprises vertical cutter and row's cutter, it is a side of one or the hold(ing)-down clip that is connected as a single entity that vertical cutter is installed in hollow shaft by dismountable connected mode, row's cutter can form by the polylith single cutting tool is regularly arranged, also can be a multiple-cutting-edge cutter that a plurality of blades are regularly arranged, row's cutter is installed between two hold(ing)-down clips, and the angle of row's edge direction and hold(ing)-down clip axis direction is preferably 60 ° between 0 °～90 °.

Technique scheme further improved be two pairs or many hold(ing)-down clip be uniformly distributed in the periphery of hollow shaft, in the every pair of hold(ing)-down clip one becomes one by gusset and hollow shaft, and a side of every pair of hold(ing)-down clip all is equipped with a vertical cutter.

And, circumferentially the locating of the hollow shaft of knife rest and transmission main shaft by key.

In addition, all leave installing hole respectively with on vertical cutter or the stationary knife that matches of row's cutter.

As shown from the above technical solution, the breaker that is used for fodder cutter that the utility model provides is by moving knife, stationary knife, the knife rest of moving knife and the formations such as transmission main shaft of drive blade holder turns are installed, knife rest is installed on the transmission main shaft by key, moving knife is divided into vertical cutter and row's cutter, row's cutter is clamped by the hold(ing)-down clip on the knife rest, vertical cutter then is installed on the knife rest by dismountable connected mode, also have installing hole on the stationary knife, such structure not only makes vertical cutter and the row's cutter of forming moving knife disassemble from knife rest easily, and knife rest also can disassemble from transmission main shaft, thereby the moving knife in this breaker and stationary knife can unload polishing again after wearing and tearing, it is replaceable that cutter or knife rest damage the back, and whole transmission main shaft or whole shredding machine are scrapped.

The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 is the general assembly drawing of rotatable parts in the utility model.

Fig. 2 is the right view of Fig. 1.

Fig. 3 for the structural representation of the stationary knife that matches of row's cutter.

Fig. 4 for the structural representation of indulging the stationary knife that cutter matches.

The breaker of the fodder cutter that the utility model provides is by moving knife 2, the knife rest 4 of moving knife 2 is installed, transmission main shaft 5 with 4 rotations of knife rest 4 connecting band movable knife racks, and the stationary knife 11 that matches with moving knife 2,15 formations such as grade, by Fig. 1, shown in Figure 2, moving knife 2 comprises vertical cutter 10 and row's cutter 1, vertical cutter 10 and row's cutter 1 all are installed on the knife rest 4, the middle part of knife rest 4 is a hollow shaft 6, hollow shaft 6 is set on the transmission main shaft 5, both circumferentially locate by key 9, axially then by screw thread or alternate manner location, transmission main shaft 5 can be by drive 8 driven rotary, drive 8 is a belt pulley among Fig. 1, it also can be sprocket wheel or gear etc. in actual the use, the periphery of empty axle 6 is provided with the hold(ing)-down clip parallel with its axis direction 7, hold(ing)-down clip 7 can be a pair of or two pairs or how right, Fig. 1, among Fig. 2 be two pairs, when hold(ing)-down clip 7 have two pairs or many to the time, should evenly distribute, a pair of hold(ing)-down clip 7 constitutes by two, wherein one can become one or is connected as a single entity by gusset 3 and hollow shaft 6, vertical 10 sides that should be installed in this piece hold(ing)-down clip 7 of cutter by dismountable connected mode (as being threaded), its opposite side then will be arranged cutter 1 with another piece hold(ing)-down clip 7 and be sandwiched among two plates, two hold(ing)-down clips 7 also should be solidly installed by dismountable connected mode (as being threaded), vertical cutter 10 and row's cutter 1 all are installed on every pair of hold(ing)-down clip 7 simultaneously, row's cutter 1 can be a multiple-cutting-edge cutter that a plurality of blades are regularly arranged, also can form by the polylith single cutting tool is regularly arranged, Fig. 1, Figure 2 shows that back one type, in this case, also locating piece 16 should be set on hold(ing)-down clip 7, the angle of the edge direction of row's cutter 1 and the axis direction of hold(ing)-down clip 7 can be between 0 °～90 °, preferably can be about 60 °, reach the stationary knife 15 of chopping purpose with matching of vertical cutter 10 or row's cutter 1 respectively, 11 all are installed on the support 13 of fodder cutter and (see Fig. 3, Fig. 4), in order to make stationary knife 15,11 install easily, dismounting and adjustment, stationary knife 15 of the present utility model, all leave installing hole 14 on 11,12, and installing

hole
