CN203866889U - Tooth top of scarifier - Google Patents

Abstract

A tooth top of a scarifier comprises a body and a tooth head, wherein a buried end of the tooth head is arc-shaped, and the edge is saw-tooth-shaped; matching holes are formed in the body, so that the tooth top of the scarifier can be mounted on a toothed bar. Compared with the prior art, the tooth top has the advantages as follows: the soil turning and loosening efficiency of the scarifier is improved, and the working efficiency is improved significantly particularly for areas with hard soil; and the tooth top is more convenient to replace.

Description

A kind of toothed tip of scarifier

Technical field

The utility model relates to a kind of ridge buster, specifically refers to a kind of toothed tip of scarifier.

Background technology

Ridge buster in engineering machinery is generally loaded on excavator or bulldozer, has the function such as fragmentation, scarifying, is mainly used in stirring soil.The shortcoming of the existence of known technology is: integrally casting, when damage, change efficiency low; Head mostly is linear or pointed, and lifting surface area is large, need to stir hard soil time, is difficult to go deep into soil, also can cause operating efficiency to decline.

Further improving the efficiency of loosening the soil is the problem that needs solution in prior art, and those skilled in the art has carried out continuous exploration and innovation.

Summary of the invention

The deficiency existing for prior art, the purpose of this utility model is to provide the toothed tip of scarifier that a kind of operating efficiency is higher.

To achieve these goals, the technical scheme that the utility model adopts is: a kind of toothed tip of scarifier, comprises body and tooth head; Described tooth head buries end for circular arc, and edge is zigzag; On described body, have mating holes, toothed tip of scarifier can be loaded on ratch.

As preferably, described body and tooth head are fixed with bolt, and body and tooth head are for removably connecting, and set bolt is 1-3.

As preferably, the sawtooth on described tooth head is uniformly distributed, and sawtooth has 5-7.

When use, crown and ridge buster ratch are fixed.According to pressure formula P=F/S, known when power one timing, the less pressure of lifting surface area is larger.While stirring soil, kiss the earth is a sawtooth on tooth head at first, and lifting surface area is little, and pressure is large, easily stirs hard soil, and along with crown gos deep into soil, other sawtooth are also started working, and active area increases, and increases the scope of digging, and ensures operating efficiency.

Body and tooth head be for removably connecting, in the time of tooth head serious wear, and replaceable tooth head, than changing whole crown, cost is lower, and volume is little lightweight, is convenient for changing.

Compared with prior art, the utility model has the advantages that: improve the ridge buster efficiency of digging, loosen the soil, especially for the hard area of soil property, operating efficiency promotes significantly; Change convenient.

Brief description of the drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model sectional drawing.

Fig. 3 is prior art cathetus shape crown schematic diagram.

Fig. 4 is prior art sharp head shape crown schematic diagram.

In figure, 1 is body, and 2 is tooth head, and 3 is bolt, and 4 is mating holes.

Detailed description of the invention

For clearly demonstrating this programme, by reference to the accompanying drawings, this programme is set forth.

A kind of toothed tip of scarifier as shown in Figure 1, comprises body 1, tooth head 2, bolt 3, mating holes 4, and body 1 is connected with tooth head 2 use bolts 3, and on body 1, both sides, front and back have two corresponding mating holes 4.Tooth head 2 loosens the soil end for circular arc, edge distribution zigzag structure, and sawtooth is uniformly distributed on tooth head 2, and sawtooth quantity is 5-7.

A kind of toothed tip of scarifier as shown in Figure 2, tooth head 2 has screwed hole away from the end that loosens the soil, and for fitted bolt 3, it is fixed on body 1, and tooth head 2 and body 1 are for removably connecting.In the time of tooth head 2 serious wear, replaceable, compared with changing whole crown, cost is lower.Body 1 is hollow-core construction, and material thickness is 1-1.5 centimetre.

For ensureing fixing between tooth head 2 and body 1, number that can corresponding increase bolt 3, is no more than at most 3.

When use, crown is installed on the ratch of ridge buster by mating holes 4 fixing pin of arranging in pairs or groups.

Claims (3)

1. a toothed tip of scarifier, comprise body (1), tooth head (2), bolt (3), mating holes (4), it is characterized in that: described body (1) is fixedly connected with tooth head (2) bolt (3), before and after body (1), both sides have two corresponding mating holes (4); Tooth head (2) the end circular arc of loosening the soil, edge distribution sawtooth.

2. a kind of toothed tip of scarifier according to claim 1, is characterized in that connecting body (1) and can be 1-3 with the set bolt (3) of tooth head (2).

3. a kind of toothed tip of scarifier according to claim 1 and 2, is characterized in that the zigzag on tooth head (2) is uniformly distributed, and quantity is 5-7.
