[0004] The purpose of the present application is to provide a Z type lifting conveying equipment, which aims to solve the problem that the turnover hopper is easy to cause material splashing and the material with high sealing requirement is easy to be polluted.

[0005] In order to achieve the above purpose, the present application provides the following technical scheme: a Z type lifting conveying equipment, comprising an elevator body, characterized in that: a hopper is rotatably connected to the chain of the elevator body, the bottom of the hopper is provided with an opening with a V-shaped cross section, a set of opening and closing mechanisms are installed at the position of the opening, and a mounting plate linked with the opening and closing mechanisms is arranged on the inner wall of the elevator body, the bottom surface of the mounting plate is provided with a tooth segment, and the tooth segment and the opening and closing mechanisms are meshed with each other.

[0006] And a limiting mechanism for limiting the opening and closing mechanism is arranged on the hopper to prevent the opening and closing mechanism from falling off.

[0008] Preferably, the opening and closing mechanism comprises a movable plate and a transfer gear, a driving gear and a synchronous rack, the movable plate is provided with two groups, which are symmetrically arranged in front and back, and the movable plate is slidably connected to the bottom surface of the opening through the limiting mechanism, the synchronous rack is arranged on the end surface of the movable plate, two groups of transfer gears are symmetrically arranged on the outer wall of the hopper, the two groups of transfer gears are respectively meshed with a group of synchronous racks, and the two groups of transfer gears are also meshed with each other, a group of driving gears meshed with the transfer gears are arranged on the top surface of a group of transfer gears, and the driving gears and the tooth segment are meshed with each other.

When the hopper reaches the discharge port, the drive gear meshes with the toothed section of the lower mounting plate, and through the reverse transmission of the adapter gear set, the two movable plates expand synchronously outward, achieving full-section opening of the bottom opening. When the hopper resets, it contacts the toothed section of the upper mounting plate, and the drive gear rotates in the opposite direction, causing the movable plates to precisely reset and close, eliminating the lag problem present in traditional gravity-based closing.

The mounting component and mounting post are connected using tapered positioning bolts, ensuring assembly accuracy without recalibration after disassembly, thus shortening maintenance time.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Reference Figures 1-6 The Z-shaped lifting and conveying device shown includes a lifting machine body 1 and a bucket 3. The bucket 3 is installed on a chain inside the lifting machine body 1. After the lifting machine body 1 is started, the bucket 3 is transported to the discharge port by the chain. Then, it cooperates with the mounting plate 2 installed on the inner wall of the lifting machine body 1. The bottom of the mounting plate 2 is provided with a toothed segment that meshes with the opening and closing mechanism on the outer wall of the bucket 3, so that the opening and closing mechanism is activated, exposing the opening at the bottom of the bucket 3, and the material is thrown out from here. The operating state of the opening and closing mechanism is stabilized by the limiting mechanism on the bucket 3.

[0024] As one implementation method in this embodiment, in order to close the opening and closing mechanism, the mounting plate 2 in this embodiment is provided with two sets, arranged one above the other. When the hopper 3 is driven to the upper layer by the chain, it contacts the toothed segment at the bottom of the upper mounting plate 2, and then drives the opening and closing mechanism to reverse, so as to close the opening.

[0025] In one embodiment of this invention, the opening and closing mechanism is as follows: the movable plate 4 is slidably connected to the opening at the bottom of the hopper 3 via a limiting mechanism. In order to drive the movable plate 4 to slide, a synchronous rack 7 is provided on the end face of the movable plate 4. Two sets of symmetrically arranged transition gears 5 are provided on the outer wall of the hopper 3. The two sets of transition gears 5 mesh with each other (at the same time, the two sets of transition gears 5 also mesh with their respective adjacent synchronous racks 7). In order to drive the transition gears 5 to rotate, thereby driving the movable plate 4 to slide on the limiting mechanism, a set of drive gears 6 that mesh with the transition gears 5 is provided above one set of transition gears 5 (on the outer wall of the hopper 3). The drive gears 6 mesh with the tooth segments. Thus, when the chain drives the hopper 3 to move and touch the tooth segments at the bottom of the mounting plate 2, the drive gears 6 rotate and drive the synchronous rack 7 to move through the transition gears 5, thereby driving the movable plate 4 to move on the limiting mechanism, opening the opening, and allowing the material to be fed in.

[0026] A spring is provided at the rotating connection of the drive gear 6 and the adapter gear 7 to assist the non-resetting of the opening and closing mechanism of the gear segment.

[0027] As one implementation method in this embodiment, the limiting mechanism is as follows: In order to provide a stable motion environment for the movable plate 4, two sets of symmetrical mounting columns 30 are provided on the outer wall of the hopper 3. Each set of mounting columns 30 is fixed with a set of mounting parts 8 by fixing bolts. The structure of the mounting parts 8 is as follows: Figure 6 As shown, two sets of extension rods 9 are provided on the end face of the mounting component 8. The extension rods 9 cooperate with the opening of the hopper 3 to limit the movement of the movable plate 4. A hole is provided at the free end of the extension rod 9, and a limit bolt 10 is threaded into the hole. A limit slide 40 corresponding to the position of the hole is provided on the outer wall of the movable plate 4. The end of the limit bolt 10 is inserted into the limit slide 40 to further limit the movement trajectory of the movable plate 4 and prevent it from falling off.

[0028] The working principle of this utility model is as follows: After the material is fed into the hopper 3 through the feed inlet of the elevator body 1, the elevator body 1 is powered on, causing the internal chain to be driven, which in turn drives the hopper 3 to move within the elevator body 1. When the hopper 3 is brought to the discharge port by the chain, the toothed segments on the bottom surface of the mounting plate 2 located at the discharge port mesh with the drive gear 6, causing the hopper 3 to drive the drive gear 6 to rotate on the toothed segments. The rotating drive gear 6 then drives the meshing adapter gear 5 to rotate. One set of adapter gears 5 drives another set of meshing adapter gears 5 to rotate, thereby driving the synchronous rack 7 to move. The moving synchronous rack 7 drives the connected movable plate to slide on the extension rod 9, exposing the opening at the bottom of the hopper 3, thus realizing the discharge of the material.

[0029] When structural maintenance is required, rotate the limiting bolt 10 on the extension rod 9 to slide the limiting bolt 10 out of the limiting groove 40, thereby disconnecting the connection between the extension rod 9 and the movable plate 4. Then, unscrew the bolts on the mounting part 8 to disconnect the connection between the mounting part 8 and the mounting column 30, thus completing the disassembly of the movable plate 4 for maintenance.

[0031] Components not described in detail in this article are existing technologies.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
