[0003] Currently, in garbage crushing equipment, generally a rotating shaft drives the knives installed on the rotating shaft to rotate for cutting and crushing garbage. At both ends of the knife shaft, bearing seats for stabilizing the shaft body are generally installed. The existing knife shaft bearing seats at both ends adopt oil seals, but during the working process, the corrosive waste liquid contained in the garbage easily penetrates into the bearing seat, resulting in bearing damage, seriously affecting the stability of the rotation of the knife shaft.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to provide a stirring knife connecting seat of a garbage recycling and treatment device to solve the above problems, which has the effect of preventing waste liquid from corroding the bearing.

A first sealing gasket is arranged at the left end of the sealing cover plate. A second sealing gasket is arranged on the left side of the bearing in the bearing seat. A third sealing gasket is arranged in the first connection hole at the left end of the bearing seat. A drainage cavity is formed between the second sealing gasket and the third sealing gasket. A first drainage port communicated with the drainage cavity is opened on the side of the bearing seat.

[0007] By adopting the above technical solution, the cutter shaft of the stirring knife passes through the first connection hole, the second connection hole and the third connection hole and then is connected to the bearing in the bearing seat. The bearing seat can oil-seal the bearing through the sealing cover plate, the first sealing washer and the second sealing washer, ensuring that the bearing can operate stably. Through the setting of the isolation seat, the third sealing washer and the drain cavity, the isolation seat and the third sealing washer can initially isolate the waste liquid to prevent the waste liquid from seeping into the bearing seat. When the waste liquid seeps into the bearing seat through the isolation seat and the third sealing washer, the drain cavity formed by the second sealing washer and the third sealing washer can collect and hold the waste liquid, and then the waste liquid is discharged through the first drain port opened on the bearing seat, effectively preventing the waste liquid from further seeping into the bearing at the second sealing washer, thereby effectively isolating the waste liquid and protecting the bearing from damage and protecting the stability of the operation of the cutter shaft.

[0008] Preferably, the outer dimension of the left end of the bearing seat is smaller than the dimensions of the right end of the bearing seat and the isolation seat, and a drain groove is formed between the left end of the bearing seat and the right end of the bearing seat and the isolation seat. The bearing seat is horizontally provided with a second drain port communicating the first drain port and the drain groove.

[0009] By adopting the above technical solution, through the design of the drain groove and the second drain port, when the waste liquid is discharged from the drain cavity, it can be drained through the second drain port and then discharged from the drain groove, improving the discharge efficiency of the bearing seat for the infiltrated waste liquid.

[0010] Preferably, a fourth sealing washer is arranged in the second connection hole of the isolation seat, and an isolation baffle is arranged in the drain groove at the right end of the isolation seat.

[0011] By adopting the above technical solution, by arranging the fourth sealing washer and the isolation baffle, the isolation effect of the isolation seat on the waste liquid is further improved, and at the same time, the isolation baffle can prevent the waste liquid from seeping in through the gap between the isolation seat and the bearing seat.

[0012] Preferably, a circular positioning ring is arranged at the position corresponding to the second connection hole at the left end of the isolation seat.

[0013] By adopting the above technical solution, the setting of the positioning ring ensures the connection accuracy and stability between the cutter shaft of the stirring knife and the bearing seat, improving the operation efficiency and safety of the equipment.

[0014] Preferably, the sealing cover plate and the bearing seat are connected by screws.

[0015] By adopting the above technical solution, the sealing cover plate connected by screws facilitates the daily inspection and maintenance work and improves the maintenance efficiency of the equipment.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] First, by setting up the isolation seat and multiple sealing washers, multiple seals are achieved, which can preliminarily isolate the waste liquid. Furthermore, through the setting of the liquid discharge cavity and the first liquid discharge port, the infiltrated waste liquid can be discharged, effectively preventing the waste liquid from soaking into the bearing interior and ensuring the normal operation and long service life of the bearing.

[0018] Second, the setting of the second liquid discharge port and the liquid discharge groove can divert the waste liquid discharged from the first liquid discharge port, improve the efficiency of waste liquid discharge, and avoid bearing damage or performance degradation caused by waste liquid accumulation.

[0019] Third, the sealing cover plate and the bearing seat are connected by screws, enabling convenient disassembly and installation during maintenance and repair, reducing the maintenance cost and time.

[0020] Fourth, the setting of the isolation baffle effectively prevents the waste liquid discharged from the liquid discharge groove from flowing back, protects the internal structure, and thus extends the service life of the equipment. Description of the Drawings

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0026] A stirring blade connecting seat of a garbage recycling and treatment device, as Figures 1 - 3 shown, includes a bearing seat 1 and an isolation seat 2. The isolation seat 2 is arranged on the left side of the bearing seat 1, and the bearing seat 1 and the isolation seat 2 are connected by bolts. First connection holes 3 and second connection holes 4 for installing a cutter shaft are respectively opened in the centers of the bearing seat 1 and the isolation seat 2. A bearing 5 is arranged in the first connection hole 3 at the right end of the bearing seat 1. A sealing cover plate 6 is arranged on the right side of the bearing seat 1. A third connection hole 7 is opened in the center of the sealing cover plate 6. The centers of the first connection hole 3, the second connection hole 4, and the third connection hole 7 are all on the same axis. A first sealing washer 8 is arranged at the left end of the sealing cover plate 6. A second sealing washer 9 is arranged on the left side of the bearing 5 in the bearing seat 1. The cutter shaft of the stirring blade passes through the first connection hole 3, the second connection hole 4, and the third connection hole 7 and then is connected to the bearing 5 in the bearing seat 1. The bearing seat 1 can seal the bearing 5 through the sealing cover plate 6, the first sealing washer 8, and the second sealing washer 9, ensuring that the bearing 5 can operate stably. A third sealing washer 10 is arranged in the first connection hole 3 at the left end of the bearing seat 1. A liquid discharge cavity 11 is formed between the second sealing washer 9 and the third sealing washer 10. A first liquid discharge port 12 communicating with the liquid discharge cavity 11 is opened on the side of the bearing seat 1. Through the settings of the isolation seat 2, the third sealing washer 10, and the liquid discharge cavity 11, the isolation seat 2 and the third sealing washer 10 can initially isolate the waste liquid, preventing the waste liquid from seeping into the bearing seat 1. When the waste liquid seeps into the bearing seat 1 through the isolation seat 2 and the third sealing washer 10, the liquid discharge cavity 11 formed by the second sealing washer 9 and the third sealing washer 10 can collect and accommodate the waste liquid, and then the waste liquid is discharged through the first liquid discharge port 12 opened on the bearing seat 1, effectively preventing the waste liquid from further seeping into the bearing 5 inside the second sealing washer 9, thereby effectively isolating the waste liquid and protecting the bearing 5 from damage and protecting the stability of the operation of the cutter shaft.

[0027] The outer dimension of the left end of the bearing housing 1 is smaller than the dimensions of the right end of the bearing housing 1 and the isolation seat 2. A drain groove 13 is formed between the left end of the bearing housing 1 and the right end of the bearing housing 1 and the isolation seat 2. The bearing housing 1 is horizontally provided with a second drain port 14 communicating with the first drain port 12 and the drain groove 13. Through the design of the drain groove 13 and the second drain port 14, when the waste liquid is discharged from the drain cavity 11, it can be drained through the second drain port 14 and then discharged from the drain groove 13, improving the discharge efficiency of the waste liquid infiltrated by the bearing housing 1. A fourth sealing gasket 15 is arranged in the second connection hole 4 of the isolation seat 2, and an isolation baffle 16 is arranged in the drain groove 13 at the right end of the isolation seat 2. By setting the fourth sealing gasket 15 and the isolation baffle 16, the isolation effect of the isolation seat 2 on the waste liquid is further improved. At the same time, the isolation baffle 16 can prevent the waste liquid from infiltrating through the gap between the isolation seat 2 and the bearing housing 1.

[0028] A circular positioning ring 17 is arranged at the position corresponding to the second connection hole 4 at the left end of the isolation seat 2. The setting of the positioning ring 17 ensures the connection accuracy and stability between the mixing knife shaft and the bearing housing 1, improves the operation efficiency and safety of the equipment. The sealing cover plate 6 is connected to the bearing housing 1 by screws. The sealing cover plate 6 connected by screws facilitates the daily inspection and maintenance work and improves the maintenance efficiency of the equipment.

[0029] When the knife shaft of the mixing knife is to be installed and connected to the bearing 5, one end of the knife shaft is passed through the positioning ring 17 on the isolation seat 2, and then passed through the isolation seat 2 and extended into the bearing housing 1 to be connected to the bearing 5 in the bearing housing 1. Finally, lubricating liquid is replenished into the bearing 5 to seal the sealing cover plate 6 to complete the installation. When the waste liquid in the garbage is to infiltrate into the bearing 5, the isolation seat 2 and the fourth sealing gasket 15 can preliminarily isolate the waste liquid. If the waste liquid further infiltrates into the bearing housing 1 and passes through the third sealing gasket 10, the waste liquid will be retained in the drain cavity 11 and discharged outward from the first drain port 12. At the same time, under the diversion of the second drain port 14, part of the waste liquid is discharged from the drain groove 13, achieving the effect of efficiently discharging the waste liquid, effectively preventing the waste liquid from further penetrating the second sealing gasket 9 and immersing into the bearing 5, reducing the corrosion and wear of the bearing 5, and reducing the processing cost.
