Description

Technical Field

[0001] The present application relates to the technical field of lifting equipment, and in particular to a lifting machine for asphalt concrete. Background Art

[0002] Mixing and stirring is a key step in the processing and production of asphalt concrete, the purpose of which is to ensure that various raw materials are evenly mixed to achieve the expected physical and chemical properties of the finished product.

[0003] In the existing asphalt concrete mixing equipment technology, a typical equipment design includes a mixing drum, a frame supporting the mixing drum, and a mixing blade or a mixing arm arranged inside the mixing drum. In addition, a mixing motor and a reducer are arranged outside the mixing drum to drive the rotation of the mixing blade or the mixing arm. A feed port is arranged at the top of the mixing drum and a discharge port is arranged at the bottom to realize the addition and discharge of materials. The material to be mixed is usually transported to a high place by an elevator and slides into the mixing drum through a downwardly inclined discharge pipe on the elevator. In particular, a rotor is arranged inside the discharge pipe to more conveniently inject the material into the feed port of the mixing drum.

[0004] However, after a period of use, a large amount of raw materials will adhere to the blades of the rotor in the discharge pipe, which not only reduces the transmission efficiency, but also requires frequent replacement of the rotor. Usually, the rotor needs to be replaced about once a year, which not only increases the maintenance cost of the equipment, but also makes the replacement process cumbersome and difficult. There is room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] Example:

[0035] Reference Figure 1 , an elevator for asphalt concrete, comprising an elevator body 1 and a discharge pipe 2 arranged on the elevator body 1, the discharge pipe 2 being arranged obliquely downward; an end of the discharge pipe 2 away from the elevator body 1 is fixedly connected with an inclined pipe 3 obliquely downward, and an inclination angle of the inclined pipe 3 with the ground is greater than an inclination angle of the discharge pipe 2 with the ground;

[0036] The material to be mixed is injected into the mixer through the discharge pipe 2 and the inclined pipe 3 in turn. The inclined setting of the discharge pipe 2 and the inclined pipe 3 can increase the gravitational potential energy of the material injected into the mixer, making it easier to inject the material.

[0037] Reference Figure 2 and Figure 3 A transition surface 31 perpendicular to the ground is provided on the portion of the inclined tube 3 close to the discharge pipe 2. A cleaning port 32 and a control door 4 for blocking the cleaning port 32 are provided on the transition surface 31 of the inclined tube 3. The control door 4 can be opened regularly, and a cleaning tool can be used to clean the material adhered to the connection between the inclined tube 3 and the discharge pipe 2.

The locking member 5 includes a support rod 51 fixed to the outer side of the control door 4 and a locking sleeve 52 slidably arranged on the outer periphery of the support rod 51;

[0039] The locking sleeve 52 can rotate around the axis of the support rod 51 and can also slide along the length direction of the support rod 51. At the same time, a locking rod 53 is fixedly arranged on the outer periphery of the locking sleeve 52, and a locking notch 331 for the locking rod 53 to be inserted and locked is provided on the locking seat 33. When the control door 4 is locked, the locking rod 53 on the locking sleeve 52 is inserted into the locking notch 331; when the control door 4 needs to be unlocked, the locking rod 53 is rotated out of the locking notch 331.

[0040] Reference Figure 3 and Figure 4 The locking seat 33 is provided with an elastic locking member 34 on the side wall of the locking notch 331, wherein the elastic locking member 34 includes a compression spring 341 and a locking protrusion 342. The locking seat 33 is provided with a placement groove 332 on the inner wall of the locking notch 331 for the compression spring 341 and the locking protrusion 342 to be placed. The locking protrusion 342 partially protrudes from the placement groove 332 under the pressure of the compression spring 341. The protruding part of the locking protrusion 342 is used to limit the locking rod 53 placed in the locking notch 331. When the locking rod 53 needs to be unlocked, the locking protrusion 342 can be manually pressed to press it into the placement groove 332 to unlock the locking rod 53.

[0041] Reference Figure 4A guiding slope 3421 is provided on the protruding portion of the locking protrusion 342 at the edge of the opening toward the locking notch 331. When the locking rod 53 moves into the locking notch 331, the outer periphery of the locking rod 53 can squeeze the protruding portion of the locking protrusion 342 along the guiding slope 3421, so that the locking rod 53 can be more smoothly inserted into the locking notch 331.
