The support lug plate 8 is provided with a positioning pin hole and a positioning groove, and when the tooth root 9 rotates upwards at the limit position, the rotation of the tooth root 9 can be limited by inserting the limiting pin 5 into the positioning pin hole of the support lug plate 8; the rotation of the tooth root 9 can be limited by inserting the limiting pin 5 when the tooth root 9 rotates to the limit through hole is exposed from the positioning groove.

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

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

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

The utility model has the beneficial effects that:

the general soil loosening teeth adopt a fixed mounting mode, the utility model adopts a hinged mode to carry out conversion of two states, and the soil loosening teeth are provided with corresponding limiting devices after conversion is completed, so that the operation is simple and the use is convenient.

Detailed Description

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

Example 1: as shown in fig. 1, the looseness tooth 2 is formed by welding a tooth root 9 and a tooth tip 10, and a rotation pin hole and a limit pin hole are formed in the looseness tooth 2. The part can also be formed by casting or forging.

Example 2:

the soil loosening tooth assembly consists of a soil loosening tooth support 1, soil loosening teeth 2, a rotating pin shaft 3, a rotating pin nut 4, a limiting pin 5, a limiting pin nut 6 and the like. The looseness tooth 2 is formed by welding a tooth root 9 and a tooth tip 10, and a rotation pin hole and a limit pin hole are formed in the looseness tooth 2. The looseness tooth support 1 consists of a reinforcing rib plate 7 and 2 support lug plates 8. 2 support otic placodes 8 weld on deep floor 7, reserve the clearance that loosens soil tooth between 2 support otic placodes.

The support lug plate 8 is provided with a rotation pin hole and a limit pin hole. The tooth root 9 is hinged between the 2 support lugs of the support 1 through the hinged through holes, and the angle of the looseness tooth relative to the support 1 is adjusted through the limiting through holes on the tooth root 9 and the limiting pins 5.

Example 3: as shown in fig. 6, a soil loosening tooth assembly is arranged at the bottom of the back of the bucket, and consists of a soil loosening tooth support 1, a soil loosening tooth 2, a rotating pin shaft 3, a rotating pin nut 4, a limiting pin 5, a limiting 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 looseness tooth support 1 and the looseness tooth 2, and is fastened through the limiting pin nut 6, so that limiting of two states of positions of the looseness tooth can be achieved.

The looseness tooth support 1 consists of a reinforcing rib plate 7 and 2 support lug plates 8. The reinforcing rib plate 7 is welded at the bottom of the original loading bucket, the 2 support lug plates 8 are welded on the reinforcing rib plate 7, and a movable gap of the soil loosening teeth is reserved between the 2 support lug plates and integrated with the loading bucket. The support lug plate 8 is provided with a rotation pin hole and a limit pin hole.

Recovery state: firstly, the limiting pin 5 is disassembled, the soil loosening teeth 2 are rotated to the position shown in fig. 4, and then the limiting pin 5 is installed back into the limiting hole of the soil loosening teeth support 1, so that the soil loosening teeth 2 are prevented from falling down, and other works of the loading bucket are prevented from being influenced.

Working state: firstly, the limiting pin 5 is disassembled, the soil loosening tooth 2 is rotated to the position shown in fig. 5, and then the limiting pin 5 is installed back into the limiting hole of the soil loosening tooth 2 to limit the working position of the soil loosening tooth 2.

Example 4: further improvements to

embodiments

2 and 3 define the distance between the locating pin hole and the locating groove in the abutment ear 8 to be equal to the distance between the hinge-mounted through hole and the limiting through hole in the tooth root 9. Thus, when the limiting through hole rotates to be overlapped with the positioning pin hole, the current looseness tooth angle can be fixed by inserting the limiting pin 5. Three installation angle adjustments of the soil loosening teeth are realized.
