A bucket structure for an excavator loader

Abstract

This invention discloses a bucket structure for an excavator loader, including a bucket with tack teeth installed on the back of the bucket. The tack teeth can be unfolded or retracted, and their state is fixed by a limiting structure. The tips (10) of the tack teeth are connected to the tooth roots (9), and the tooth roots (9) have hinged through holes and limiting through holes. This invention adds a tack function to the existing functions of the loader bucket without affecting the use of the original bucket functions, making the loader bucket multifunctional.

Description

Technical Field

[0001] This invention relates to a soil loosening tooth arrangement structure on a bucket. Background Technology

[0002] Currently, buckets only have teeth on the front side, and the bucket's tilting angle is limited. It is difficult to use the front teeth for digging on some special digging surfaces. For example, when digging on a vertical surface, the bucket needs to be tilted upwards to its limit, which also limits the height and makes it impossible to dig to lower working surfaces. Installing loosening teeth on the back of the bucket can effectively improve the applicability of loosening working surfaces, but installing teeth on the back of the bucket will affect normal digging operations. Summary of the Invention

[0003] This invention aims to provide a simple and easy-to-operate soil loosening tooth structure. The invented soil loosening tooth has two working states: it needs to be retracted when loading and transporting, and it is only lowered when needed. While ordinary soil loosening teeth adopt a fixed installation mode, this invention uses a hinged method to switch between the two states. After the switch is completed, there is a corresponding limiting device, which makes the operation simple and convenient.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A bucket structure for an excavator loader includes a bucket with ripping teeth mounted on the back of the bucket. The ripping teeth can be extended or retracted, and a limiting structure is used to fix the state of the ripping teeth.

[0006] Install 2-3 loosening teeth on the ridge line on the back of the bucket.

[0007] Install 2-10 loosening teeth on the back of the bucket, evenly distributed or arranged with varying pitch.

[0008] The tip 10 of the loosening tooth is connected to the root 9, and the root 9 has a hinged through hole and a limiting through hole.

[0009] The width of tooth root 9 is smaller than that of tooth tip 10.

[0010] The tooth root 9 is hinged to the support 1 through the hinged through hole, and the angle of the loosening tooth relative to the support 1 is adjusted by the limiting through hole and the limiting pin 5 on the tooth root 9.

[0011] The support 1 has two support lugs 8, and the tooth root 9 is hinged between the two support lugs 8 by a rotating shaft pin 3.

[0012] The support ear plate 8 has a positioning pin hole and a positioning groove. When the tooth root 9 is in the extreme position of upward rotation, the limiting pin 5 can be inserted into the positioning pin hole of the support ear plate 8 to restrict the rotation of the tooth root 9. When the tooth root 9 rotates to the point where the limiting through hole is exposed from the positioning groove, the limiting pin 5 can be inserted to restrict the rotation of the tooth root 9.

[0013] Support 1 consists of a reinforcing rib plate 7 and two support lug plates 8. The reinforcing rib plate 7 is a bent structure, and the two support lug plates are welded vertically to the reinforcing rib plate 7.

[0014] The reinforcing rib 7 is installed at the bottom of the back of the bucket.

[0015] The distance between the positioning pin hole and the positioning groove on the support ear plate 8 is equal to the distance between the hinged through hole and the limiting through hole on the tooth root 9.

[0016] The beneficial effects of this invention are:

[0017] The addition of a soil loosening function to the existing functions of the loading bucket, without affecting the use of the original bucket functions, makes the loading bucket multifunctional.

[0018] Conventional soil loosening teeth are installed in a fixed manner, while this invention uses a hinged method to switch between two states. After the switch is completed, there is a corresponding limiting device, which makes the operation simple and convenient. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] Example 1: As Figure 1 The bucket is equipped with tack teeth. Two to three tack teeth can be arranged along the ridge, or more tack teeth can be evenly distributed on the back of the bucket, or they can be arranged in a certain array.

[0027] like Figure 2 As shown, the loosening tooth 2 is welded from the tooth root 9 and the tooth tip 10, and the loosening tooth 2 is provided with a rotating pin hole and a limiting pin hole. This part can also be formed by casting or forging.

[0028] Example 2: Based on Example 1, the installation structure of the loosening teeth is further designed.

[0029] like Figure 4 The loosening tooth assembly consists of loosening tooth support 1, loosening tooth 2, rotating pin 3, rotating pin nut 4, limiting pin 5, and limiting pin nut 6.

[0030] The loosening tooth 2 is hinged to the loosening tooth support 1 by the rotating pin 3 and the rotating pin nut 4. The loosening tooth 2 can rotate up and down around the rotating pin 3 to change its position. The limiting pin 5 is inserted into the limiting hole on the loosening tooth support 1 and the loosening tooth 2 and is fastened by the limiting pin nut 6, which can limit the two states of the loosening tooth.

[0031] like Figure 3 As shown, the loosening tooth support 1 consists of a reinforcing rib plate 7 and two support ear plates 8. The reinforcing rib plate 7 is welded to the bottom of the original loading bucket, and the two support ear plates 8 are welded to the reinforcing rib plate 7. A clearance for the loosening tooth is reserved between the two support ear plates, and it is integrated with the loading bucket. The support ear plates 8 are provided with rotating pin holes and limiting pin holes.

[0032] This invention employs articulated soil loosening teeth, which are rotated via articulation to achieve the soil loosening teeth recovery state (see...). Figure 5 ) and working status (see Figure 6 The system switches between states and limits them at two extreme positions to meet user requirements.

[0033] Action description:

[0034] Recovery status: First, remove the limit pin 5, then rotate the loosening tooth 2 to... Figure 5 At the indicated position, reinstall the limiting pin 5 back into the limiting hole of the loosening tooth support 1 to prevent the loosening tooth 2 from falling down and affecting other operations of the loading bucket.

[0035] Working status: First remove the limit pin 5, then rotate the loosening gear 2 to... Figure 6 At the indicated position, reinstall the limiting pin 5 back into the limiting hole of the loosening tooth 2 to limit the working position of the loosening tooth 2.

[0036] Example 3: Further, based on Example 2, the distance between the positioning pin hole and the positioning groove on the support ear plate 8 is equal to the distance between the hinged through hole and the limiting through hole on the tooth root 9. Thus, when the limiting through hole rotates to coincide with the positioning pin hole, inserting the limiting pin 5 can fix the current loosening tooth angle, achieving a second working state with a different unfolding angle.
