Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment, specifically to a waste compression device with a flexible automatic reset movable guide rail. Background Technology

[0002] The current underground landscape station has a fixed frame that is fixed in a pit. Inside the fixed frame is a lifting support platform that can move the garbage bin from the ground to the underground. When the garbage bin is full, the support platform can lift the garbage bin from the underground to the ground, making it easy for a trailer to move the garbage bin away. It can save a lot of ground space while maintaining the beauty and cleanliness of the ground environment and effectively reduce the emission of garbage odor.

[0003] Once the trash can is full, it needs to be transferred from the support platform to the trailer. This process requires the use of a movable guide rail at one end of the support platform. This is because there is a gap between the support platform and the fixed frame (to avoid interference between the lifting of the support platform and the fixed frame). The rollers at the bottom of the trash can need the movable guide rail to support them so that they can pass through the gap.

[0004] The current movable guide rail and support platform are hinged at one end. A limit block is set on the support platform and below the movable guide rail to ensure that the movable guide rail can remain horizontal or only swing upward. When the garbage bin is completely transferred to the support platform, the movable guide rail needs to be swung to the support platform. In this way, when the garbage bin is full of garbage and lifted from underground to the ground, the movable guide rail only needs to be swung from the support platform to a horizontal state.

[0005] However, in actual use, it is often overlooked to swing the movable guide rail onto the support platform. This doesn't affect the support platform's ability to lower the trash can. Specifically, when the support platform lowers the movable guide rail, after contacting the top of the fixed frame, the movable guide rail swings upward and then around the fixed frame. After passing the fixed frame, the movable guide rail returns to a horizontal position, and the support platform, movable guide rail, and trash can all descend to their lowest positions simultaneously. However, when the support platform moves the trash can upward, because the movable guide rail remains horizontal, the top fixed frame interferes with the movable guide rail, preventing the support platform from rising to the ground. The operator must then descend into the pit to swing the movable guide rail onto the support platform to restart the upward movement of the support platform.

[0006] Due to the frequent occurrence of the above-mentioned problems in actual operation, and in view of the problems existing in the prior art, this utility model designs and manufactures a garbage compression device with a flexible automatic reset function movable guide rail to overcome the above-mentioned defects. Summary of the Invention

[0007] To address the problems existing in the prior art, this utility model provides a waste compression device with a flexible automatic reset movable guide rail. When the movable guide rail descends with the support platform, it automatically swings onto the support platform after contacting the top of the fixed frame. When the support platform is moved to the ground and the waste bin is dragged away from the support platform, the movable guide rail can automatically open under the push of the rollers at the bottom of the waste bin, ensuring support during the transfer of the waste bin.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a garbage compression device with a flexible automatic reset function movable guide rail, including a pit, a fixed frame in the pit, the fixed frame including upper and lower horizontal square annular frames, and a number of vertical support beams between the two horizontal square annular frames.

[0009] The fixed frame is provided with a support platform that can be raised and lowered. One end of the support platform is provided with a hinge seat. A hinge shaft is rotatably connected to the hinge seat. A movable guide rail is fixed on the hinge shaft. One end of the movable guide rail is rotatably connected to the hinge seat through the hinge shaft.

[0010] A limit block is fixed on the fixed frame at the bottom of the hinge seat, and the limit block enables the movable guide rail to remain horizontal or to swing upward only.

[0011] A first fixing member and a second fixing member are also provided on the fixed frame near the hinge seat. The first fixing member and the second fixing member are respectively provided on both sides of the movable guide rail. The first fixing member is provided above the hinge seat, and the second fixing member is provided below the hinge seat. A first connecting member and a second connecting member are respectively provided on both sides of the middle position of the movable guide rail. The first connecting member and the first fixing member are provided on the same side of the movable guide rail. The second connecting member and the second fixing member are provided on the same side of the movable guide rail. A first tension spring is provided between the first connecting member and the first fixing member, and a second tension spring is provided between the second connecting member and the second fixing member.

[0012] Preferably, a positioning block is provided on the hinge seat and above the movable guide rail, the positioning block being able to restrict the movable guide rail from flipping onto the support platform.

[0013] Preferably, when the first tension spring pulls the movable guide rail to swing toward the support platform, the positioning block enables the movable guide rail to be perpendicular to the support platform.

[0014] Preferably, when the movable guide rail is nearly horizontal, the tension of the second tension spring is greater than the tension of the first tension spring;

[0015] When the movable guide rail is away from the horizontal state, the tension of the first tension spring is greater than the tension of the second tension spring.

[0016] Preferably, the support platform is provided with two sliding plates, and the movable guide rail is provided at the same end of both sliding plates.

[0017] Preferably, the side of the skateboard away from the other skateboard has a limiting upright.

[0018] Preferably, limiting baffles are provided on both sides of the movable guide rail.

[0019] Preferably, the width of the movable guide rail gradually increases as it moves away from the support platform.

[0020] Preferably, the first fixing member, the second fixing member, the first connecting member, and the second connecting member are all configured as screws, and limit nuts are screwed onto the screws to restrict the movement of the first tension spring and the second tension spring, respectively.

[0021] The advantages of this utility model are:

[0022] 1. This utility model utilizes a first tension spring at the top to cause the movable guide rail to swing upwards, and a second tension spring at the bottom to cause the movable guide rail to swing downwards. When the movable guide rail is in a horizontal state, the tension of the second tension spring is greater than that of the first tension spring, thus ensuring the stability of the movable guide rail in a horizontal state. This prevents the garbage bin from being transferred from above the movable guide rail. When the support platform descends, causing the movable guide rail to touch the fixed frame, the movable guide rail swings towards the support platform at a certain angle. At this point, the tension of the first tension spring is greater than that of the second tension spring, ensuring the stable and automatic retraction of the movable guide rail. This prevents interference between the movable guide rail and the fixed frame when the support platform rises again.

[0023] 2. This utility model uses limiting blocks and positioning blocks to further limit the swing angle of the movable guide rail, preventing the movable guide rail from entering the swing dead angle and affecting subsequent use. Attached Figure Description

[0027] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0028] like Figure 1 , Figure 2 As shown, a waste compression device with a flexible automatic reset movable guide rail includes a pit, in which a fixed frame (not shown in the figure) is provided. The fixed frame includes two horizontal square ring frames, the upper horizontal square frame being flush with the ground, and several vertical support beams being provided between the two horizontal square ring frames.

[0029] The fixed frame is equipped with a lifting support platform 2. The support platform 2 can drive the garbage bin 1 into the pit. At this time, the height of the top of the garbage bin 1 is lower than the horizontal square frame above. Specifically, the support platform 2 is lifted and lowered by four hydraulic cylinders 5, which are connected to the hydraulic station.

[0030] The present invention provides a hinge seat 6 at one end of the support platform 2, a hinge shaft 7 is rotatably connected to the hinge seat 6, and a movable guide rail 4 is fixed on the hinge shaft 7. One end of the movable guide rail 4 is rotatably connected to the hinge seat 6 through the hinge shaft 7. The movable guide rail 4 extends away from the support platform 2, the purpose of which is to form a bridge between the support platform 2 and the fixed frame (there is a gap between the support platform 2 and the fixed frame to avoid the lifting and lowering of the support platform 2 being affected by the fixed frame).

[0031] A limit block is fixed on the fixed frame at the bottom of the hinge seat 6. The limit block allows the movable guide rail 4 to remain horizontal or to swing upwards only.

[0032] A first fixing member 11 and a second fixing member 8 are also provided on the fixed frame near the hinge seat 6. The first fixing member 11 and the second fixing member 8 are respectively provided on both sides of the movable guide rail 4. The first fixing member 11 is provided above the hinge seat 6, and the second fixing member 8 is provided below the hinge seat 6. A first connecting member 13 and a second connecting member 10 are respectively provided on both sides of the middle position of the movable guide rail 4. The first connecting member 13 and the first fixing member 11 are provided on the same side of the movable guide rail 4, and the second connecting member 10 and the second fixing member 8 are provided on the same side of the movable guide rail 4. A first tension spring 12 is provided between the first connecting member 13 and the first fixing member 11, and a second tension spring 9 is provided between the second connecting member 10 and the second fixing member 8.

[0033] A positioning block 17 is provided on the hinge seat 6 and above the movable guide rail 4. The positioning block 17 can restrict the movable guide rail 4 from flipping onto the support platform 2. Specifically, when the first tension spring 12 pulls the movable guide rail 4 to swing towards the support platform 2, the positioning block 17 can make the movable guide rail 4 perpendicular to the support platform 2. This utility model uses the limiting block and the positioning block 17 to further limit the swing angle of the movable guide rail 4, preventing the movable guide rail 4 from entering a swing dead angle and affecting subsequent use.

[0034] When the movable guide rail 4 is close to the horizontal state, the tension of the second tension spring 9 is greater than the tension of the first tension spring 12; when the movable guide rail 4 is far from the horizontal state, the tension of the first tension spring 12 is greater than the tension of the second tension spring 9.

[0035] By using the upper first tension spring 12 to drive the movable guide rail 4 to swing upward and the lower second tension spring 9 to drive the movable guide rail 4 to swing downward, the tension of the second tension spring 9 is greater than that of the first tension spring 12 when the movable guide rail 4 is in a horizontal state. This ensures the stability of the movable guide rail 4 in a horizontal state and does not affect the transfer of the trash can 1 from above the movable guide rail 4. When the support platform 2 descends, causing the movable guide rail 4 to touch the fixed frame, the movable guide rail 4 swings towards the support platform 2 at a certain angle. The tension of the first tension spring 12 is greater than that of the second tension spring 9, ensuring the stable automatic retraction of the movable guide rail 4 and avoiding interference between the movable guide rail 4 and the fixed frame when the support platform 2 rises next time.

[0036] The support platform 2 of this utility model is equipped with two sliding plates 3, and each sliding plate 3 has a movable guide rail 4 at the same end, which matches the bottom rollers 16 of the trash can 1. A limiting plate 14 is provided on the side of the sliding plate 3 away from the other sliding plate 3, and limiting baffles 15 are provided on both sides of the movable guide rail 4, so as to ensure the stability of the trash can 1 during the movement.

[0037] The width of the movable guide rail 4 gradually increases as it moves away from the support platform 2. This is to prevent the trailer from parking inaccurately, which could cause the garbage bin 1 to shift its position during towing and damage the movable guide rail 4.

[0038] Preferably, the first fixing member 11, the second fixing member 8, the first connecting member 13, and the second connecting member 10 are all configured as screws, and the screws are screwed with limit nuts to restrict the movement of the first tension spring 12 and the second tension spring 9, respectively.

[0039] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
