Description

Technical Field

[0001] The present invention relates to the field of organic waste resource utilization equipment, and particularly to a 180-degree flipping and discharging elevator using a multi-link device. Background Art

[0002] In the process of treating organic waste for resource utilization, in order to better implement the process requirements or save the floor area for equipment installation, the vertical three-dimensional process layout has become a common implementation case. During the implementation of the vertical three-dimensional process layout, the elevator has become an indispensable execution device.

[0003] At present, the elevators used in the above-mentioned organic waste resource utilization process on the market generally can only be selected as the ones installed on garbage trucks or improved trash can elevators, vertically installed bucket elevators, screw conveyors or bucket elevators with a certain inclination angle. During the process implementation, it is often necessary to lift the entire trash can or fermentation frame filled with materials. At this time, only the improved trash can elevator can be selected. However, due to the limitations of its own structure, the flipping and discharging angle of the conventional trash can elevator is less than 135 degrees, and during the large-angle flipping process, the action is completed by the cooperation of inertia and spring tension, and the working state is unstable. At the same time, organic waste usually contains long fiber substances, which will adhere to the trash can or fermentation frame. The 135-degree flipping often cannot make them slide freely, and repeated flipping or manual auxiliary scraping is required to complete the discharging, which not only reduces the efficiency but also increases the labor cost. The improved trash can elevator can achieve a flipping and discharging angle greater than 135 degrees, but an additional set of rotary drive devices needs to be added, making the equipment structure more complex and the manufacturing cost higher. At the same time, the cables of the added rotary drive device will move up and down along with the lifting support frame, which is not beautiful and the practicability is also reduced.

[0004] Therefore, when lifting with a trash can or fermentation frame with materials, an elevator with a more stable operation, a simpler structure and a larger flipping angle is needed. Summary of the Invention

[0023] Embodiment 1 Please refer to Figure 1 As shown, a 180-degree flip and discharge elevator implemented by the present invention mainly consists of a track rack 1, a lifting support frame 2, a rotating link 3, a moving link 4, a front floating link 5, a rear floating link 6, a pushing link 7, a guide pulley 8, an anti-retreat slide rail 9, a driving device 10, an anti-retreat roller 11, and an anti-retreat roll 12; the lifting support frame 2 is installed inside the track rack 1; the rotating link 3 is installed on the upper part of the back surface of the lifting support frame 2; the moving link 4 is hinged to the outer end of the rotating link 3; the rear floating link 6 is hinged to the inner end of the rotating link 3; one end of the front floating link 5 is hinged to the moving link 4, and the other end is hinged to the rear floating link 6; the pushing link 7 is hinged to the front floating link 5; there are a total of 6 guide pulleys 8, with 2 installed on each side of the moving link 4 and 1 installed on each side of the pushing link 7; the anti-retreat slide rail 9 is installed at the top end of the rotating link 3; the lifting driving device 10 is installed at one end near the top of the track rack 1; the traction member 11 is connected between the lifting driving device 10 and the pushing link 7; the anti-retreat roller 12 is installed at the top end of the track rack 1.

[0024] In this embodiment, when the equipment is running, driven by the lifting drive device 10, the pushing link 7 is driven by the upward traction force to drive the lifting support frame 2, the rotating link 3, the moving link 4, the front floating link 5, the rear floating link 6, and the guide pulley 8 to move from a low position to a high position along the track frame 1. When the top group of guide pulleys 8 moves to the end of the track frame 1, it cannot continue to move; the moving link 4 cannot continue to move either, and the pushing link 7 continues to push upward. The front floating link 5 and the rear floating link 6 are stretched apart when they are pushed upward, and the force is transmitted to the rotating link 3, driving the lifting support frame 2 to flip along a specific center point under the restriction of the anti-retraction roller 11 and the anti-retraction slide rail 9, so that the lifting support frame 2 can be freely flipped from 90 degrees to 180 degrees.

[0025] Embodiment 2 See also Figure 2 As shown, the material discharging elevator capable of 180-degree flipping in the second embodiment of the present invention is similar to the first embodiment, except that: In order to complete the functionality of the elevator, it is necessary to add a clamping device, specifically a locking pressure rod 13, a transition link 14, a cam link 15, a cam roller 16, a tension spring 17, a hanging plate 18 and a wedge block 19; the transition link 14 is installed between the locking pressure rod 13 and the cam link 15; the locking pressure rod 13 is installed on the back of the lifting support frame 2 and above the transition link 14; the cam link 15 is below the transition link 14; the cam roller 16 is installed at both ends of the cam link 15; one end of the tension spring 17 is installed on the cam link 15, and the other end is installed on the lifting support frame 2; the hanging plate 18 is installed in the upper middle position of the front of the lifting support frame 2; the wedge block 19 is installed at the lower end of the track frame 1.

[0026] In this embodiment, the clamping device works as follows.

In conjunction with the hanging plate 18, the trash can or the fermentation frame can be locked on the lifting support frame 2. When the lifting support frame 2 drops to the lowest position, the cam roller 16 presses onto the wedge block 19, and the cam connecting rod 15 is squeezed. The squeezing force is transmitted to the locking pressure rod 13 through the transition connecting rod 14 to rotate it open, forming an open state.
