[0002] The side-dumping working device of a loader is the main component for realizing the operation of the loader in a narrow space, and is mainly used for tunnels, narrow filling ports of special mixing stations, operation ends of mountain roads, etc. The side-dumping working device of a loader mainly consists of a side-dumping bucket, a side-dumping bracket, a side-dumping oil cylinder and side-dumping pin shafts, etc. The side-dumping pin shaft is used to connect the sleeve of the side-dumping bucket and the ear seat of the side-dumping bracket. Under the action of the side-dumping oil cylinder, the side-dumping bucket rotates around the bracket along the pin shaft by a certain angle to realize the side-dumping function.

[0003] However, in the prior art, since the sleeve of the bucket is processed at both ends with a step left in the middle, the processing efficiency is low and the concentricity of the sleeve cannot be guaranteed. At the same time, after the whole working device is assembled, due to the structural limitation of the sleeve, the bush, as a wearing part, cannot be replaced separately, and it is necessary to plane off the sleeve of the whole side-dumping bucket together with the support plate for replacement, resulting in a large cost.

[0005] Preferably, a fixing bolt is threadedly connected to the top of the side-dumping pin shaft, a soft pad is sleeved on the outer wall of the fixing bolt, the material of the soft pad is a soft material, the bottom of the soft pad is in contact with the top of the ear seat, and the outer wall of the ear seat is fixedly connected to the outer wall of the side-dumping bracket.

[0006] Preferably, the outer wall of the side-dumping pin shaft is slidably connected to the inner wall of the ear seat, limiting blocks are slidably connected to the inner walls on both sides of the side-dumping bush, circular holes are provided in the walls of the limiting blocks, and the outer wall of the sleeve is fixedly connected to the outer wall of the side-dumping bucket.

[0007] Preferably, a locking bolt is slidably connected to the inner wall of the limiting block, the locking bolt is slidably connected to the inner wall of the limiting block through the circular hole, the outer wall of the locking bolt is slidably connected to the inner wall of the side-dumping bush, the outer wall of the locking bolt is slidably connected to the inner wall of the isolation sleeve, and a sealing washer is clamped on the inner wall of the ear seat.

[0023] The outer wall of the side-dumping pin 2 is slidably connected to the inner wall of the ear seat 9, limiting blocks 11 are slidably connected to the inner walls on both sides of the side-dumping bushing 6, the outer wall of the sleeve 12 is fixedly connected to the outer wall of the side-dumping bucket 8, a locking bolt 10 is slidably connected to the inner wall of the limiting block 11, the position of the limiting block 11 is restricted by the locking bolt 10, thereby restricting the position of the side-dumping bushing 6, and the outer wall of the locking bolt 10 is slidably connected to the inner wall of the side-dumping bushing 6.

[0024] The outer wall of the locking bolt 10 is slidably connected to the inner wall of the isolating sleeve 7, a sealing washer 5 is clamped in the inner wall of the ear seat 9, the inner wall of the sealing washer 5 is in contact with the outer wall of the side-dumping pin 2, and the outer wall of the sealing washer 5 is in contact with the outer wall of the sleeve 12. The ear seat 9 and the sleeve 12 are sealed by the sealing washer 5 to prevent dust from entering the sleeve 12, and the outer wall of the limiting block 11 is in contact with the outer wall of the sealing washer 5.

[0025] Working principle:

[0026] In use, first slide the sleeve 12 in the side-dumping bucket 8 onto the lug 9 on the side-dumping bracket 1. Then, it is necessary to maintain the position of the bucket and the bracket. Next, install the fittings in the side-dumping mechanism 13 into the sleeve 12. Then, it is necessary to fix the positions of the lug 9 and the sleeve 12. Just slide the side-dumping pin 2 through the lug 9 and into the sleeve 12. Then, slip the fixing bolt 4 over the cushion 3 and then screw the fixing bolt 4 into the side-dumping pin 2. The position of the side-dumping pin 2 is fixed by the cushion 3 and the fixing bolt 4, thereby fixing the sleeve 12 on the lug 9.

[0027] There are two groups of side-dumping bushings 6 in the sleeve 12, corresponding to the upper and lower side-dumping pins 2 respectively, which can withstand the friction generated during the operation of the loader. There is a spacer sleeve 7 between the two groups of side-dumping bushings 6, and there is lubricating oil in the spacer sleeve 7. Therefore, the lubricating oil in the spacer sleeve 7 can play a lubricating role during the operation of the loader.

[0028] Limit blocks 11 are provided at one end of the two side-dumping bushings 6 close to the sealing washer 5. Therefore, the position of the side-dumping bushing 6 can be restricted by passing the locking bolt 10 through the two limit blocks 11 and then screwing the nut onto the locking bolt 10. The sealing washer 5 between the lug 9 and the sleeve 12 plays a role in anti-wear and sealing, preventing dust from entering the sleeve 12 when the loader is working.

[0029] When after-sales work needs to be carried out on the loader, just remove the fixing bolt 4 and take out the side-dumping pin 2. The side-dumping bushing 6 inside the sleeve 12 can be knocked out together with the spacer sleeve 7 by knocking on any side of the sleeve 12, thus reducing the after-sales time.

[0030] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
