Embodiment 1

[0021] Such as figure 1 , figure 2 , image 3 , Figure 4 , a spiral hoist in this embodiment includes a fixed pipe 1, a feeding pipe 2, a connecting pipe 3 and a driving device 4, the fixed pipe 1 is arranged above the connecting pipe 3, the fixed pipe 1 is hollow and two The end is open cylindrical, the top of the fixed pipe 1 is provided with a discharge port 11, the side of the fixed pipe 1 is provided with a guide ear 12, and the inside of the wall of the fixed pipe 1 is provided with a hollow No. 1 connecting cavity 13; the No. 1 The connecting chamber 13 is in the shape of a ring, the bottom of the No. 1 connecting chamber 13 is connected to the air, and the inner wall of the No. 1 connecting chamber 13 is provided with a No. 1 thread 131 .

[0022] Such as figure 1 , Figure 5 , Image 6 , the lifting tube 2 is hollow and cylindrical with both ends open, the lifting tube 2 is located below the fixed tube 1, the side of the lifting tube 2 is provided with the sam...

Embodiment 2

[0026] The basic structure of the screw hoist of this embodiment is the same as that of Embodiment 1, the difference is that two guide ears 12 are arranged on the side of the fixed pipe 1, and the distance between the two guide ears 12 is similar to that of the first embodiment. The angle is 180 degrees.

Embodiment 3

[0028] The basic structure of the screw hoist of this embodiment is the same as that of Embodiment 1, the difference is that three guide ears 12 are arranged on the side of the fixed pipe 1, and the angle between the two guide ears 12 is similar is 90 degrees.

[0029] When the screw hoist of Embodiment 1-3 is in use, the driving motor 41 drives the driving gear 42 to rotate in one direction, and the driving gear 42 drives the connecting pipe 3 to rotate in one direction; The direction of rotation of 131 is opposite to that of No. 2 thread 221 in the lifting pipe 2, the rotation of the connecting pipe 3 makes the lifting pipe 2 move downward relative to the connecting pipe 3, and at the same time the lifting pipe 2 moves downward relative to the fixed pipe 1, and the non-return piece 23 Open, the material enters into the lifting pipe 2; then the driving gear 42 drives the connecting pipe 3 to rotate in another direction; Closed, the material in the lifting pipe 2 is lifted to...

Abstract

The invention relates to a device for lifting objects, specifically a spiral hoist, comprising a fixed pipe, a material lifting pipe, a connecting pipe and a driving device, the fixed pipe is arranged above the connecting pipe, the fixed pipe is hollow and Cylindrical with both ends open, the top is provided with a discharge port, the side is provided with guide ears, and the inside of the tube wall is provided with a hollow No. 1 connection chamber whose lower part is connected to the air; Cylindrical, the side of the lifting pipe is provided with the same number of guide forks as the number of guide ears, the bottom of the pipe wall is provided with an inwardly protruding flange, and a non-return piece is provided above the flange; the inner wall of the second connection chamber is provided with a The No. 1 thread turns to the opposite No. 2 thread; a straight depression is arranged around the outer wall of the connecting pipe, and a thread is arranged on the inner wall of the connecting pipe. The invention adopts a vertical cylindrical lifting mechanism, which can greatly reduce the occupied area of ​​the hoist and save space resources.

Description

technical field [0001] The invention relates to a device for lifting objects, in particular to a spiral hoist. Background technique [0002] In the lifting process of granular or powdery materials such as grain and flour, hoists are usually used to complete the work; The hoist is used in it. The traditional bucket elevator is mostly used in the vertical direction or near the vertical direction with a large inclination angle to continuously lift the transport machinery of granular or broken materials. It has a simple structure, a small footprint, a large lifting height, stable work, low noise, and high speed. It is fast and widely used in various production fields, but the traditional hoist occupies a large area, and it will appear crowded in places where equipment is concentrated. Contents of the invention [0003] Aiming at the problems of the hoist in the prior art, such as large floor space, the present invention provides a spiral hoist, which adopts a vertical cylind...
