[0028] As mentioned in the background, the discharge door of the garbage compression storage machine in the related art is a switching component for discharging garbage after garbage compression is completed. Since the pressure generated during garbage compression is large, the discharge door needs to bear high-strength pressure and maintain sealing, which leads to difficulty in lubricating the bearing on the discharge door, poor heat dissipation, and potential risks of bearing damage and fracture.
[0029] Based on the above description, one or more embodiments of the present application provide a discharge door of a waste treatment device and a waste treatment device containing the same. In the discharge door of the waste treatment device, two bearing seats are arranged on the discharge door shaft, a tapered roller bearing is arranged in at least one of the bearing seats, and the two tapered roller bearings are oppositely arranged and symmetrically mounted on the bearing seats. Thus, the tapered roller bearings constitute bidirectional axial bearing members, and when the waste compression pressure acts on the door body, the tapered roller bearings can effectively resist the axial compression recoil force during waste compression, thereby enhancing the overall load-bearing strength of the discharge door.
[0030] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings of the specification and specific embodiments.
[0031] As shown in Figure 1 , the discharge door of the waste treatment device described in the embodiments of the present application comprises a door body 1 and two bearing seats. The center of the door body 1 is provided with a discharge door shaft 18. One side of the door body 1 is connected with a barrel 5 for storing waste, and the other side is fixed with a square tube 20 through the discharge door shaft 18. The square tube 20 extends along the radial direction of the door body 1. The two bearing seats are sequentially arranged on the discharge door shaft 18. One of the bearing seats is fixedly connected with the door body 1, and the other bearing seat is fixedly connected with the square tube 20. Two tapered roller bearings are arranged in at least one of the bearing seats. The two tapered roller bearings are oppositely arranged and symmetrically mounted on the bearing seats.
[0032] As can be seen from the above description, the discharge door described in the embodiments of the present application uses two bearing seats to jointly pass through the discharge door shaft 18. Two tapered roller bearings are arranged in at least one of the bearing seats. The tapered roller bearings can effectively enhance the axial bearing capacity, thereby ensuring the overall load-bearing strength of the door body 1 during waste compression and rebound.
[0033] It should be noted that, as shown in Figure 2 , in the discharge door in the embodiments of the present application, the square tube 20 is fixedly connected with the bearing seat on the discharge door shaft 18, and the free end of the square tube 20 is connected with the door opening mechanism 27 of the waste treatment device. Other structure components not mentioned in the embodiments of the present application, such as the opening mode of the door body 1, the aforementioned door opening mechanism 27, and other connection structures of the barrel 5 and the door body 1, can be arranged according to the related art of waste compression storage machines, and will not be described herein.
[0034] As shown in Figure 1 , in the embodiments of the present application, two tapered roller bearings are arranged in each of the bearing seats, and the two tapered roller bearings in each of the bearing seats pass through the discharge door shaft 18.
[0035] In the above embodiments, each tapered roller bearing includes a wide end and a narrow end, and in any of the bearing housings, the narrow ends of the two tapered roller bearings are arranged opposite to each other. The wide end of the tapered roller bearing refers to the end with a relatively large cross section, and the narrow end refers to the end with a relatively small cross section. When an external axial load, such as a garbage compression recoil force, acts, the two tapered roller bearings are simultaneously pressed, and the axial force is converted into a radial expansion component by the taper angle, which counteracts each other, thereby avoiding shafting movement of the two tapered roller bearings.
[0036] Further, as shown in Figure 3 , at least one of the bearing housings is configured with an oil injection hole 7 extending in the radial direction thereof, and the inner side wall of the bearing housing is configured with an annular oil groove 28 located between the two tapered roller bearings. One end of the oil injection hole 7 communicates with the oil groove 28, and the other end communicates with the outside of the bearing housing. The oil injection hole 7 is configured to inject lubricating oil into the tapered roller bearings through the oil groove 28.
[0037] Herein, specifically, as shown in Figure 4 , an adjusting ring 22 is arranged between the two tapered roller bearings, the adjusting ring 22 is embedded in the oil groove 28, and a plurality of through holes 11 are arranged on the adjusting ring 22 in the circumferential direction. The lubricating oil enters the through holes 11 through the oil injection hole 7 and is injected into the tapered roller bearings through the through holes 11.
[0038] Further, the side close to the door body 1 is the first bearing housing 23, and the side away from the door body 1 is the second bearing housing 16. The fixing nut 6 and the round nut stop washer 26 axially fix the two first tapered roller bearings 21 on the discharge door shaft 18. The assembled parts are pressed into the first bearing housing 23, the outer ring of the first tapered roller bearing is connected with the first bearing housing 23 in interference, and the second hexagonal bolt 9 and the second spring washer 10 fix the first bearing cover 8 and the first bearing housing 23.
[0039] It can also be seen that the adjusting ring 22 has the functions of separating the two tapered roller bearings and dispersing the lubricating oil. The lubricating oil entering the adjusting ring 22 is uniformly dispersed to the tapered roller bearings on both sides by the centrifugal force, thereby realizing the lubrication performance and heat dissipation performance of the tapered roller bearings.
[0040] Generally, the bearing housing is also provided with a lubricating oil cup 24 communicating with the oil injection hole 7, which is used to inject lubricating oil into the oil injection hole 7.
[0041] In the embodiments of the present application, for example, as shown in Figure 1As shown, the door body 1 and the barrel 5 are sandwiched with a cloth sandwiching rubber plate 25, which comprises multiple cloth layers and rubber layers. The cloth sandwiching rubber plate 25 formed by the multiple cloth layers and the rubber layers is not easy to tear and has a long service life.
[0042] An exemplary assembly structure of the discharge door of the garbage disposal equipment is as follows:
[0043] The first bearing seat 23 is provided with an oil groove 28, and the oil injection hole 7 is connected to the oil groove 28. The adjusting ring 22 is provided with four through holes 11, so that the lubricating oil in the lubricating oil cup 24 can enter the first tapered roller bearing 21 through the oil injection hole 7, thereby ensuring the lubrication of the first tapered roller bearing 21.
[0044] The second bearing seat 16 is provided with an oil groove 28, and the oil injection hole 7 is connected to the oil groove 28. The lubricating oil in the lubricating oil cup 24 can enter the second tapered roller bearing 15 through the oil injection hole 7, thereby ensuring the lubrication of the second tapered roller bearing 15.
[0045] By changing the size of the bearing retainer 17 or the adjusting ring 22, the gap of the two first tapered roller bearings 21 or the two second tapered roller bearings 15 can be adjusted, thereby ensuring the normal use of the bearings.
[0046] The reinforcing rib 2, the first bearing seat 23, and the reinforcing plate 14 are welded to the door body 1, and the cloth sandwiching rubber plate 25 is fixed to the door body 1 by the first hexagonal bolt 3 and the first spring washer 4.
[0047] The fixing nut 6 and the round nut stop washer 26 axially fix the first tapered roller bearing 21 to the discharge door shaft 18. The assembled parts are pressed into the first bearing seat 23, the outer ring of the first tapered roller bearing 21 is connected to the first bearing seat 23 in an interference fit, and the second hexagonal bolt 9 and the second spring washer 10 fix the first bearing cover 8 to the first bearing seat 23.
[0048] The second bearing seat 16 is welded to the square tube 20, and the second bearing seat 16 is provided with two second tapered roller bearings 15. The discharge door shaft 18 is sleeved in the two second tapered roller bearings 15, and the end of the discharge door shaft 18 is provided with the bearing retainer 17, the third spring washer 12, and the hexagonal nut 13. The third hexagonal bolt 29 and the fourth spring washer 30 fix the second bearing cover 19 to the second bearing seat 16.
[0049] The second bearing seat 16 and the first bearing seat 23 are both provided with the lubricating oil cup 24. The lubricating oil can be pressed into the first tapered roller bearing 21 and the second tapered roller bearing 15 through the lubricating oil cup 24, thereby ensuring that the first tapered roller bearing 21 and the second tapered roller bearing 15 can be fully lubricated and cooled.
[0050] The assembled parts constitute an integral discharge door, which covers the barrel 5. The barrel 5 rotates to drive the discharge door to rotate. At this time, the discharge door rotates, and the discharge door shaft 18 can not rotate or can rotate. The door is connected with the door opening mechanism 27 to realize the opening and closing of the discharge door.
