Description

Technical Field

[0001] The utility model relates to the technical field of excavator production, in particular to an excavator bucket capable of preventing bucket teeth from falling off. Background Art

[0002] An excavator, also known as an excavator or a backhoe, is an earth-moving machine that uses a bucket to dig materials above or below the bearing surface and loads them into transport vehicles or unloads them to stockpiles. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loosened soil and rocks. Judging from the development of construction machinery in recent years, the development of excavators has been relatively rapid. Excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of excavators are: operating weight (mass), engine power and bucket capacity.

[0003] Existing buckets are structural products, which are composed of tooth seat plates, bottom plates, side plates, wall plates, ear plates, back plates, bucket teeth, tooth seats, guard plates or bucket corners and other parts. In order to facilitate the replacement of bucket teeth, a bucket locks the bucket teeth and the tooth seat through a pin shaft, but during use, the pin shaft is easy to loosen and fall off, causing the bucket teeth to fall off, thus affecting the normal use of the bucket. Therefore, we propose a new excavator bucket that prevents bucket teeth from falling off. Utility Model Content

[0004] The main purpose of the utility model is to provide an excavator bucket which can prevent bucket teeth from falling off, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an excavator bucket for preventing bucket teeth from falling off, comprising a bucket body, a plurality of hinged ear plates are arranged on the top of the bucket body, a tooth seat plate is fixedly connected to one side of the bottom of the bucket body, a plurality of tooth seats are evenly fixedly connected to one side of the tooth seat plate, a non-through fixing groove is opened at one end of the tooth seat, a fixing component is clamped in the inner cavity of the fixing groove, the fixing component comprises a threaded block, a connecting plate, a fixing block, a clamping block, an installation groove, and a spring, the fixing block is slidably connected to the inner cavity of the fixing groove, clamping blocks are symmetrically arranged on both sides of the fixing block, a connecting plate is fixedly connected to one side of the fixing block, a threaded block is fixedly connected to one side of the connecting plate, and a bucket tooth is fixedly connected to one end of the fixing component.

[0006] As a further description of the above technical solution, the two side walls of the tooth seat are symmetrically provided with protective grooves, the inner side walls of the protective grooves are provided with clamping grooves that pass through to the fixing grooves, a non-through accommodating groove is provided on one side of the bucket tooth, and the inner side walls of the accommodating grooves are provided with threaded grooves.

[0007] As a further description of the above technical solution, non-through installation grooves are symmetrically opened on both sides of the fixed block, a spring is fixedly connected to the side wall of the inner cavity of the installation groove, a clamping block is fixedly connected to one side of the spring, the clamping block is slidably connected to the inner cavity of the installation groove, and the clamping block is clamped and connected to the inner cavity of the clamping slot.

[0008] As a further description of the above technical solution, the threaded block is meshedly connected with the threaded groove, and the connecting plate is engaged with the inner cavity of the accommodating groove, and the connecting plate is fixedly connected with the side wall of the inner cavity of the accommodating groove by a plurality of fixing screws.

[0009] As a further description of the above technical solution, magnet one is symmetrically fixedly connected to the side wall of the inner cavity of the protective groove, a cover plate is snap-connected to the inner cavity of the protective groove, magnet two is symmetrically fixedly connected to the side wall of the cover plate, the opposite surfaces of magnet one and magnet two are opposite magnetic surfaces, and a non-through trapezoidal groove is opened on the other side wall of the cover plate.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. By setting a fixing assembly, when the bucket teeth need to be replaced, the block in the slot is pressed, and the block compresses the spring, so that the block and the spring slide into the inner cavity of the installation slot, so that the block moves away from the slot. At this time, the bucket teeth are moved to one side until the block and the fixing block are separated from the inner cavity of the fixing slot, and the bucket teeth can be disassembled. Then the fixing screws of the fixed receiving slot and the connecting plate are unscrewed, and the threaded block is unscrewed from the threaded slot, and the damaged bucket teeth can be replaced. After tightening the new bucket teeth and the threaded block in the fixing assembly and fixing them with the fixing screws, the fixing block in the fixing assembly is inserted into the fixing slot of the inner cavity of the tooth holder. At this time, the fixing block and the block on it also move in the inner cavity of the fixing slot until the block is inserted into the slot. The spring ejects the block from the installation slot and makes the block completely inserted into the slot, so that the fixed connection between the fixing assembly and the tooth holder can be completed, thereby completing the installation of the bucket teeth. This device is convenient for installing and disassembling bucket teeth, and is firmly fixed, which can effectively prevent the bucket teeth from falling off, and is highly practical.

[0012] 2. By setting up protective grooves, cover plates, etc., and cooperating with the cover plates and protective grooves, the fixed components are placed in a relatively closed space, thereby preventing the block from being accidentally touched by the outside world, causing the block to fall out of the inner cavity of the groove, causing the bucket teeth to fall off, and at the same time preventing sand and gravel from entering the inner cavity of the fixing groove or the installation groove from the groove, thereby damaging the fixed components or the bucket teeth, thereby improving the anti-falling performance of the bucket teeth and increasing the service life of the bucket teeth.

When the bucket tooth 4 or the fixing assembly 5 is damaged, it is only necessary to remove the fixing assembly 5 from the inner cavity of the fixing groove 6, and then separate the bucket tooth 4 from the fixing assembly 5, so that the damaged parts can be replaced separately.

[0024] Specifically, Figure 3 As shown, the inner side wall of the protective groove 16 is symmetrically fixedly connected with a magnet 12, the inner side of the protective groove 16 is snap-connected with a cover plate 8, the side wall of the cover plate 8 is symmetrically fixedly connected with a magnet 2 13, the opposing surfaces of the magnet 12 and the magnet 2 13 are opposite magnetic surfaces, and the attraction between the magnet 12 and the magnet 2 13 makes the cover plate 8 firmly snap-fitted on the protective groove 16, so that the fixing component 5 is in a relatively closed space, thereby preventing the block 5.4 from being accidentally touched by the outside world, so that the block 5.4 falls out of the inner cavity of the slot 7, causing the bucket tooth 4 to fall off, and at the same time preventing sand and gravel from entering the inner cavity of the fixing groove 6 or the installation groove 5.5 from the slot 7, thereby damaging the fixing component 5 or the bucket tooth 4, while improving the anti-falling performance of the bucket tooth 4 and increasing the service life of the bucket tooth 4. A non-through trapezoidal groove 14 is formed on the other side wall of the cover plate 8. When the cover plate 8 needs to be opened, the cover plate 8 can be lifted up by inserting a crowbar into the inner cavity of the trapezoidal groove 14 and abutting against the side wall of the inner cavity of the trapezoidal groove 14, thereby facilitating the removal of the cover plate 8 from the inner cavity of the protective groove 16.
