Description
Technical Field
The utility model belongs to the mechanical equipment field especially relates to a large discharge screw feeder.
Background
The screw feeder utilizes the extrusion of the blades and the cylinder body to push the material flow to move horizontally through friction force, so under the working condition of high power, the abrasion of the blades cannot be avoided, the thickness and the diameter of the abraded blades are reduced, and the conveying capacity is limited. The usual solution is to provide wear liners on the blades, with the replacement of wear liners to achieve normal function.
The common screw feeder is to open the casing and then to remove the screw-fixed lining plate for replacement. However, in long-term extrusion and abrasion work, the threads and the lining plate are easy to rust and fail, and the replacement is not convenient.
At present, no equipment can improve the situation, the existing screw feeder is not applied to large treatment capacity, and is used in the environment with small feeding amount, and particularly, the existing screw feeder is not suitable for coal blending and feeding in the coal conveying process of a thermal power plant and a coal mine.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a large-discharge screw feeder which is convenient to install, use and maintain and has excellent performance.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the driving mechanism is arranged at one end of the casing, the spiral shaft is arranged in the casing, one end of the spiral shaft is connected with the driving mechanism, the feeding hole is arranged above the casing, the discharging hole is arranged below the casing, the spiral shaft comprises a spiral middle shaft and blades, the blades are spirally arranged on the spiral middle shaft, a plurality of wear-resistant lining plates attached to the blades are arranged on the front sides of the blades, each wear-resistant lining plate is closely attached to each blade through one auxiliary shaft part, a connecting hole is formed in the auxiliary shaft part, and the auxiliary shaft part is fixedly connected to the spiral middle shaft through the connecting hole and a bolt.
In the technical scheme, the auxiliary shaft part and the wear-resistant lining plate are at least divided into 6 sections along the 360-degree length of the spiral central shaft.
In the technical scheme, the contact surface of the auxiliary shaft part and the wear-resistant lining plate is a knurled surface.
In the technical scheme, a sealing cover plate for sealing is arranged at the connecting hole.
The utility model has the advantages that: 1. the wear-resistant lining plate can be quickly and conveniently fixed and detached, and the working condition that the lining plate with large feeding amount is seriously worn can be adapted; 2. the lining plate does not need to be provided with a threaded hole, the processing technology is simple, and the manufacture is more convenient and economic; 3. the auxiliary shaft part further strengthens the strength of the blades and the middle shaft, and is suitable for the requirement of a large-displacement working condition.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of a part of the screw shaft, the auxiliary shaft part and the wear-resistant lining plate in fig. 1.
Wherein: 1. the spiral middle shaft, 2, an auxiliary shaft part, 3, a wear-resistant lining plate, 4, blades, 5, a driving mechanism, 6, a feeding hole, 7, a machine shell, 8, a discharging hole, 9 and a base.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
The large-discharge screw feeder comprises a base 9, a driving mechanism 5 arranged on the base 9, a casing 7, a feed inlet 6, a discharge outlet 8, a screw shaft, an auxiliary shaft part 2 and wear-resistant lining plates 3, wherein the driving mechanism 5 is arranged at one end of the casing 7, the screw shaft is arranged in the casing 7, one end of the screw shaft is connected with the driving mechanism 5, the feed inlet 6 is arranged above the casing 7, the discharge outlet 8 is arranged below the casing 7, the screw shaft comprises a screw middle shaft 1 and blades 4, the blades 4 are spirally arranged on the screw middle shaft 1, the wear-resistant lining plates 3 attached to the blades are arranged on the front surfaces of the blades 4, each wear-resistant lining plate 3 is closely attached to the blade through one auxiliary shaft part 2, the auxiliary shaft part 2 is provided with a connecting hole, and the auxiliary shaft part 2 is connected and fastened to the screw middle shaft 1 through the.
In the above technical solution, the contact surface of the auxiliary shaft part 2 and the wear-resistant lining plate 3 is a knurled surface to increase the friction force. The wear-resistant lining plate 3 is not required to be provided with drill threads, and can be integrally formed by bending and destressing after shearing and blanking.
In the technical scheme, the auxiliary shaft part and the wear-resistant lining plate are at least divided into 6 sections along the 360-degree length of the spiral central shaft. The fan-shaped angle of the auxiliary shaft part 2 and the wear-resistant lining plate 3 does not exceed 60 degrees, the arc deformation of the contact surface is less, the processing is convenient, and the integral structure is stable after the combination.
In the technical scheme, a sealing cover plate for sealing is arranged at the connecting hole. The sealing cover plate is used for plugging the connecting hole, so that coal cannot run into the connecting hole, the auxiliary shaft part and the wear-resistant lining plate can be detached only by taking down the sealing cover plate and unscrewing the bolt during detachment, and the wear-resistant lining plate is convenient to replace. And the connecting hole sets up on the countershaft part, makes the easy wearing and tearing piece of screw feeder: the wear-resistant lining plate is thoroughly simplified, the cost is greatly reduced, and the stability of the whole equipment is improved.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
