Description

Technical Field

[0001] The utility model relates to the technical field of aggregate conveyors, in particular to a concrete aggregate conveyor. Background Art

[0002] The high-angle concrete aggregate conveyor can convey at a large angle or even vertically. It is widely used because of its large conveying capacity, small footprint, and simple maintenance. Its usage scenario requires that its conveyor belt maintain a large angle of inclination, so it is particularly important to design it to ensure that the conveyed material does not slide down. In the concrete production process, the transportation of a variety of materials is involved, and multiple conveyors are required to cooperate, so the floor area is very large. The way to effectively reduce the area occupied by the conveying process is to use a high-angle conveyor. For the transportation of granular materials such as sand mix, it is even more necessary to ensure that the material will not slide down or be scattered at a large inclination angle. In addition, for the safety of use, the dust generated by small granular materials during the transportation process should be minimized to prevent it from floating around, posing an unsafe hazard to the equipment and operators.

[0003] In view of the above problems, a concrete aggregate conveyor is proposed to solve the above problems. Utility Model Content

Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it designate a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1

[0028] Reference Figures 1 and 2 , which is the first embodiment of the present utility model, provides a concrete aggregate conveyor, including a conveying unit 100, including a frame 101, a conveying drive 102 is provided on the frame 101, and a conveying belt 103 is annularly provided on the conveying drive 102;

[0029] The dustproof unit 200 includes a feed dust cover 201, a conveying dust cover 202 and a discharge dust cover 203. The feed dust cover 201 and the discharge dust cover 203 are arranged at both ends of the conveying dust cover 202, and the feed dust cover 201 is arranged at the lower end of the conveyor belt 103, and the discharge dust cover 203 is arranged at the upper end of the conveyor belt 103.

[0030] Furthermore, transverse partitions 103a are equidistantly arranged on the horizontal line of the conveyor belt 103 to realize large-angle conveying of materials. Side guards 103b are continuously arranged on the edges of both sides of the conveyor belt 103 to prevent the materials from slipping and scattering. The material thereof has a certain flexibility and is preferably shaped as a wavy side guard. There is a gap between the transverse partition 103a and the side guard 103b.

[0031] Furthermore, the feed dust cover 201 is arranged at the horizontal section at the lower end of the conveyor belt 103 to prevent the generation of scattered dust during feeding. Its upper end is the feed port 201a, which is connected to the conveying dust cover 202 on one side along the forward direction of the conveyor belt 103.

[0032] Furthermore, the conveying dust cover 202 is connected and fixed to the frame 101 and covers the conveyor belt 103 to prevent dust from being generated during the conveying and lifting of materials at a large angle, and its upper end is connected to the discharge dust cover 203.

[0033] Furthermore, the discharge dust cover 203 is arranged on the lower side of the upper end of the conveyor belt 103, and covers multiple transverse partitions 103a of the conveyor belt 103 to prevent the material from being scattered and generating dust during output. It also covers multiple transverse partitions 103a, and its lower end is the discharge port 203a, which can avoid the situation in which, under high-speed transportation, the material is difficult to be fully output in a short distance due to inertia caused by the transverse partitions 103a and is scattered.

[0034] In summary, by setting the dustproof unit 200 on the conveyor belt 103, it is possible to effectively prevent concrete aggregate and other materials from generating scattered dust during the transportation process. At the same time, the setting of the discharge dustproof cover 203 can prevent dust from floating during discharge.

[0035] Example 2

[0036] Reference Figures 1 to 3, which is the second embodiment of the present utility model. Based on the previous embodiment, this embodiment provides a concrete aggregate conveyor, and also includes: a leveling unit 300, including a uniformly distributed rotating shaft 301, a leveling rotating shaft 302, a baffle 303 and a leveling driving member 304. The leveling unit 300 is arranged at the horizontal section at the lower end of the conveying dust cover 202, and the uniformly distributed rotating shaft 301 and the leveling rotating shaft 302 are connected and matched through the leveling driving member 304.

[0037] Furthermore, the uniform distribution shaft 301 is rotatably connected to the inside of the horizontal section at the lower end of the conveying dust cover 202, and its function is to enable the materials carried by the transverse partition 103a to be evenly distributed to both sides. A first partition plate 301a is arranged in a ring at the center position, and uniform distribution blades 301b are symmetrically arranged on both sides of the first partition plate 301a. The outermost circumference of the uniform distribution blade 301b is tangent to the upper end of the transverse partition 103a, and the pitch of the uniform distribution blade 301b is half of the diameter of its outermost circumference, which can better distribute the material evenly to both sides instead of being pushed to the subsequent conveyor belt 103.

[0038] Furthermore, the sweeping shaft 302 is rotatably connected to the inside of the horizontal section at the lower end of the conveying dust cover 202, and is arranged parallel to the uniform distribution shaft 301 along the forward direction of the conveyor belt 103. A second partition plate 302a is arranged in a ring at its center position, and sweeping blades 302b are symmetrically arranged on both sides of the second partition plate 302a. The outermost circumference of the sweeping blade 302b is tangent to the upper end of the transverse partition 103a, and the pitch of the sweeping blade 302b is twice the diameter of its outermost circumference, which can better level the material with the height of the transverse partition 103a as the limit.

[0039] Furthermore, the baffle 303 is fixedly arranged inside the horizontal section at the lower end of the conveying dust cover 202, and its lower end is a material height limit plate 303a, which is arc-shaped and fits the sweeping blade 302b. When there is some fast-moving material that cannot be leveled by the above-mentioned components, the baffle 303 can be aligned to limit it, and it can be leveled again by the sweeping blade 302b.

[0040] Furthermore, the sweeping driving member 304 includes a driving motor 304 a cooperating with the uniform distribution shaft 301 and a chain 304 b connecting the uniform distribution shaft 301 and the sweeping shaft 302 .

[0041] Furthermore, a first sprocket 301c is provided on one side of the uniformly distributed rotating shaft 301, and a second sprocket 302c is provided on the corresponding side of the sweeping rotating shaft 302, and the two are connected and matched by a chain 304b.

[0042] During use, when the conveyor belt 103 is started, the drive motor 304a is started synchronously, and the conveyor belt 103 and the chain 304b rotate in the same direction. When the material passes through the uniform distribution shaft 301, the uniform distribution blade 301b will push the concentrated accumulation material entering through the feed port 201a left and right, so that it is evenly distributed along the direction of the diaphragm 103a. When it passes through the leveling shaft 302, the leveling blade 302b will level the evenly distributed material so that it can be kept as high as the diaphragm 103a as possible.

[0043] In summary, the sweeping unit 300 pushes the material placed on the conveyor belt 103 to both sides instead of pushing it to the conveyor belt 103 behind, effectively avoiding the problem of material accumulation and spillage at a large inclination angle and the concentrated accumulation of material at the feed port during high-speed material transportation, which affects the transportation efficiency.
