Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to an inclined screw elevator. Background Art

[0002] Inclined screw elevator is a kind of equipment which uses screw as lifting member to lift materials upward at an angle. Usually, a sealing tube is installed on the outside of the screw, and a feed hopper and a discharge port are installed on both ends of the sealing tube. The screw rotates inside the sealing tube, and the material entering the bottom of the sealing tube is spirally conveyed to the discharge port at the upper end for discharge. It is a simple and efficient material conveying equipment.

[0003] This type of equipment is mainly divided into two types: fixed and adjustable. The fixed type is generally used in fixed places to lift materials, while the adjustable type is generally used in scenarios where the height of the output object is uncertain. The height of the material lifting needs to be adaptively adjusted each time. The latter is more widely used. The existing adjustable inclined screw elevator usually places a bracket at the bottom of the front end of the sealing tube, and the material lifting height is adjusted by changing the height of the bracket. In actual application, it is necessary to use fixing parts to fix it after each adjustment, otherwise it is easy to slide down and tip over naturally. At the same time, after the sealing tube angle is adjusted, the inclination angle of the feed hopper changes. When the inclination angle is too large, the material is easy to fall from the upper hopper. For this reason, a specially provided inclined screw elevator is provided to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides an inclined screw elevator, which solves the problem that the existing inclined screw elevator needs to be fixed with fixing parts after each adjustment, otherwise it is easy to slide down and tip over naturally. At the same time, after the sealing tube angle is adjusted, the inclination angle of the feed hopper changes. When the inclination angle is too large, the material is easy to fall from the upper hopper.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A tilted screw elevator is designed, comprising a metal outer tube and a screw rod rotatably arranged inside the metal outer tube, a driving motor is installed at the bottom end of the metal outer tube, a feeding pipe and a feeding hopper are installed at the upper and lower ends of the metal outer tube respectively, and an inclination adjusting member is arranged at the bottom of the metal outer tube;

[0007] The tilt angle adjustment member comprises a support arm, a flip support rod, a sliding ring and an adjustment screw rod, wherein the support arm is horizontally arranged below the metal outer tube, the sliding ring is slidably connected to the outer wall of the metal outer tube, the two ends of the flip support rod are respectively movably hinged to the support arm and the sliding ring, the adjustment screw rod is rotatably connected to the outer wall of the metal outer tube, and the adjustment screw rod is threadedly connected to the sliding ring;

[0008] A connecting hose is installed between the feed hopper and the metal outer pipe.

[0009] Preferably, the inclination adjusting member further includes a driving member fixedly arranged on the outer surface of the metal outer pipe, and the bottom end of the adjusting screw rod is rotatably connected inside the driving member.

[0010] Preferably, the driving member includes a support seat, a turbine and a worm. The support seat is fixedly arranged on the outer wall of the metal outer pipe, and the end of the adjusting screw rod is rotatably connected in the support seat. The turbine is fixedly sleeved on the outer surface of the end of the adjusting screw rod. The worm is rotatably connected inside the support seat and meshes with the turbine.

[0011] Preferably, the driving member further includes a fixing ring, a driving rod and a turntable. The fixing ring is fixedly sleeved on the outer wall of the metal outer pipe, and the support seat is integrally formed with the top of the fixing ring. The driving rod is rotatably connected in the support seat. The worm is fixedly sleeved on the outer surface of one end of the driving rod, and the turntable is fixedly installed at the other end of the driving rod.

[0012] Preferably, a sealing cover is fixedly installed at the top of the metal outer pipe, and the top end of the adjusting screw rod is rotatably connected to the outer surface of the sealing cover.

[0013] Preferably, a base is arranged below the feed hopper. The bottom end of the metal outer pipe is rotatably connected inside the base, and the support arm is fixedly installed with the base.

[0014] Preferably, a column is fixedly installed between the feed hopper and the base.

[0015] The utility model discloses an inclined screw elevator, and its beneficial effects are as follows:

[0016] By rotating the turntable, the driving rod drives the worm to rotate, so that the turbine drives the adjusting screw rod to rotate. At this time, the sliding ring on the outer surface of the adjusting screw rod slides along the metal outer pipe, and at this time, the top end of the turning support rod moves, so as to adjust the inclination angle of the whole metal outer pipe. During this process, the self-locking of the turbine and worm is utilized to prevent the metal outer pipe from self-sliding and tipping during use. At the same time, during the rotation of the metal outer pipe, the metal outer pipe and the feed hopper are connected by a hose, so that the feed hopper always remains on the top of the base without moving, avoiding the problem of material feeding and dropping when the inclination angle is too large.
