Disclosure of Invention

The invention aims to provide a soil loosening tooth structure which is simple in structure and convenient to operate. The soil loosening teeth have two working states, and need to be folded when carrying out loading and shoveling, and put down when in use; the universal scarification tooth adopts a fixed mounting mode, the invention adopts a hinged mode to convert two states, and a corresponding limiting device is arranged after the conversion is finished, so that the operation is simple and the use is convenient.

In order to achieve the purpose, the invention adopts the following technical scheme:

a bucket structure of a loader-digger comprises a bucket, soil loosening teeth are mounted on the back of the bucket and can be unfolded or folded, and the state of the soil loosening teeth is fixed by a limiting structure.

2-3 ripping teeth are arranged on the ridge line of the back of the bucket.

2-10 scarification teeth are arranged on the back of the bucket and are uniformly distributed or arranged in a variable-torque mode.

The tooth point 10 of the tooth that loosens the soil is connected on tooth root 9, has hinge dress through-hole and spacing through-hole on the tooth root 9.

The width of the tooth root 9 is smaller than the tooth tip 10.

The tooth root 9 is hinged on the support 1 through a hinged through hole, and the angle of the loosening teeth relative to the support 1 is adjusted through a limiting through hole in the tooth root 9 and a limiting pin 5.

The support 1 is provided with two support ear plates 8, and a tooth root 9 is hinged between the two support ear plates 8 through a rotating shaft pin 3.

The support lug plate 8 is provided with a positioning pin hole and a positioning groove, and the limiting pin 5 is inserted into the positioning pin hole of the support lug plate 8 when the tooth root 9 is at the upward rotating limit position so as to limit the rotation of the tooth root 9; the tooth root 9 can be restricted from rotating by inserting the restricting pin 5 when the restricting through hole is exposed from the positioning groove.

The support 1 consists of a reinforcing rib plate 7 and two support ear plates 8, the reinforcing rib plate 7 is of a bending structure, and the two support ear plates are vertically welded on the reinforcing rib plate 7.

The reinforcing rib plate 7 is installed at the bottom of the back of the bucket.

The distance between the positioning pin hole and the positioning groove on the support lug plate 8 is equal to the distance between the hinged through hole and the limiting through hole on the tooth root 9.

The invention has the beneficial effects that:

increase the function of loosening the soil on loading scraper bowl current function basis to can not influence the use of original scraper bowl function, make loading scraper bowl have the multifunctionality.

The common scarification teeth adopt a fixed mounting mode, the scarification tooth adopts a hinged mode, the two states are converted, and a corresponding limiting device is arranged after the conversion is finished, so that the scarification tooth is simple to operate and convenient to use.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1: as shown in fig. 1, the back of the bucket is provided with ripping teeth, the ripping teeth may be arranged along ridge lines by 2-3, or a greater number of ripping teeth are uniformly distributed on the back of the bucket, or may be arranged according to a certain array.

As shown in fig. 2, the ripping teeth 2 are formed by welding a tooth root 9 and a tooth tip 10, and the ripping teeth 2 are provided with a rotation pin hole and a limit pin hole. The parts may also be formed by casting or forging.

Example 2: the mounting structure of the ripping teeth is further designed on the basis of embodiment 1.

As shown in fig. 4, the ripping tooth assembly is composed of a ripping tooth support 1, ripping teeth 2, a rotating pin shaft 3, a rotating pin nut 4, a limit pin 5, a limit pin nut 6, and the like.

The soil loosening teeth 2 are hinged to the soil loosening tooth support 1 through a rotating pin shaft 3 and a rotating pin nut 4, and the soil loosening teeth 2 can rotate up and down around the rotating pin shaft 3 to change positions; the limiting pin 5 is inserted into limiting holes in the soil loosening tooth support 1 and the soil loosening teeth 2 and is fastened through a limiting pin nut 6, and the soil loosening teeth can be limited in two state positions.

As shown in fig. 3, the ripping tooth support 1 is composed of a reinforcing rib plate 7 and 2 support ear plates 8. Deep floor 7 welds in former loading scraper bowl bottom, and 2 support otic placodes 8 weld on deep floor 7, reserve the clearance that loosens the soil tooth between 2 support otic placodes, and the loading scraper bowl is integrated. The support ear plate 8 is provided with a rotating pin hole and a limiting pin hole.

According to the invention, the hinged scarification teeth are adopted, the recovery state (see figure 5) and the working state (see figure 6) of the scarification teeth are switched in a hinged rotation mode, and the limit fixing is carried out at the limit positions of the two states, so that the use requirement of a user is met.

Explanation of the operation:

and (3) recovery state: the limiting pin 5 is detached firstly, the soil loosening teeth 2 are rotated to the position shown in fig. 5, and then the limiting pin 5 is installed back to the limiting hole of the soil loosening tooth support 1, so that the soil loosening teeth 2 are prevented from falling down and affecting other work of the loading bucket.

The working state is as follows: the limiting pin 5 is detached firstly, the soil loosening teeth 2 are rotated to the positions shown in fig. 6, then the limiting pin 5 is installed back to the limiting holes of the soil loosening teeth 2, and the working positions of the soil loosening teeth 2 are limited.

Example 3: on the basis of embodiment 2, further, the distance between the positioning pin hole and the positioning groove on the support lug plate 8 is equal to the distance between the hinged through hole and the limiting through hole on the tooth root 9, so that the limiting through hole rotates to coincide with the positioning pin hole, and the current soil loosening tooth angle can be fixed by inserting the limiting pin 5. A second operating state with a different deployment angle is achieved.
