Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a belt conveyor for concrete. Background Art

[0002] The belt conveyor, also known as the belt conveyor, is widely used in various industries such as household appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food, etc. The belt conveyor has the advantages of strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can be conveniently programmed and automated. The belt conveyor is an indispensable equipment for concrete conveying. When conveying concrete, due to the fluidity of concrete, ordinary smooth conveyor belts will cause concrete spillage, so relevant structures need to be set up to prevent concrete spillage; there are two existing conventional methods. One is to use a skirted conveyor belt, but this structure has the problem that the residual material in the skirt (wrinkle) cannot be cleaned. The other is to directly set vertical retaining edges at the edges of the conveyor belt. However, if the retaining edges are too high, when the retaining edges pass through the rollers, due to the lack of sufficient turning radius, tearing will occur. If the retaining edges are too low, the concrete cannot be blocked; therefore, the existing two structural forms both have their own defects, so a new structure is urgently needed to solve the above problems.

[0031] Referring to Figure 1 and Figure 2 As shown in

[0032] A belt conveyor for concrete according to an embodiment of the present utility model includes: a frame 100, an endless conveyor belt 200, and a material retaining assembly. The endless conveyor belt 200 is arranged on the frame 100, and the endless conveyor belt 200 is connected with a driving assembly for driving its movement. Specifically, in this embodiment, the endless conveyor belt 200 is horizontally arranged for horizontally conveying materials. The driving assembly includes a driving roller 140, a redirecting roller 150, and a driving member. Both the driving roller 140 and the redirecting roller 150 are rotatably installed on the frame 100. The driving roller 140 and the redirecting roller 150 are arranged at intervals along the length direction of the endless conveyor belt 200. The endless conveyor belt 200 is wound around the driving roller 140 and the redirecting roller 150. The driving member is connected to the driving roller 140 to drive the driving roller 140 to rotate. The driving member can adopt a combination of a motor and a reducer.

[0033] The material retaining assembly includes two material retaining plates 300. Both of the two material retaining plates 300 are installed on the frame 100. Both of the two material retaining plates 300 are distributed along the length direction of the endless conveyor belt 200. The two material retaining plates 300 are respectively located on the opposite sides in the width direction of the endless conveyor belt 200, and both of the two material retaining plates 300 are located on the upper side of the endless conveyor belt 200 in the conveying section. The lower end of the material retaining plate 300 is in contact with the outer surface of the endless conveyor belt 200. The materials are blocked by the two material retaining plates 300 on the opposite sides in the width direction of the endless conveyor belt 200 to prevent the materials from overflowing from the edge of the endless conveyor belt 200. In this embodiment, the materials can be concrete.

[0034] The belt conveyor for concrete in the embodiment of the present utility model is provided with baffle plates 300 on opposite sides in the width direction of the endless conveyor belt 200, so that the baffle plates 300 are higher than the endless conveyor belt 200, and the lower ends of the baffle plates 300 are in contact with the outer surface of the endless conveyor belt 200, thereby blocking the materials on the endless conveyor belt 200 and preventing the materials from overflowing from the edge of the endless conveyor belt 200. Since the baffle plates 300 are installed on the frame 100 rather than on the endless conveyor belt 200, the height of the baffle plates 300 can be set relatively large, so as to ensure a good blocking effect on the materials on the endless conveyor belt 200. And because the baffle plates 300 are in a plate-like structure without wrinkles, it is very convenient to clean the residues on the baffle plates 300.

[0035] It can be understood that the belt conveyor for concrete in the embodiment of the present utility model further includes two end cleaners 160, and the end cleaners 160 are used to clean the residues on the outer surface of the endless conveyor belt 200. Among them, the two end cleaners 160 are located on opposite sides in the length direction of the endless conveyor belt 200, and the end cleaners 160 are in contact with the outer surface of the return section of the endless conveyor belt 200. The end cleaners 160 are common structures in the prior art, so the specific structures and principles thereof will not be described in detail herein.

[0036] Referring to Figure 1 and Figure 2 As shown, in some embodiments of the present utility model, guide strips 210 are respectively provided on opposite sides of the endless conveyor belt 200 in its own width direction. The guide strips 210 and the endless conveyor belt 200 are of an integral structure, and the guide strips 210 protrude from the outer surface of the endless conveyor belt 200. The guide strips 210 are located on the opposite sides of the two baffle plates 300. In this embodiment, the guide strips 210 are located at the edges in the width direction of the endless conveyor belt 200. It can be understood that there is moisture in the concrete, and there may be installation errors during the installation of the baffle plates 300, resulting in the lower ends of the baffle plates 300 not being able to contact the outer surface of the endless conveyor belt 200. And the endless conveyor belt 200 may also have a certain subsidence during the conveying process, resulting in the lower ends of the guide plates not being able to contact the outer surface of the endless conveyor belt 200. In this way, a small amount of water and concrete will overflow from the gap between the baffle plates 300 and the endless conveyor belt 200 to the side of the baffle plates 300 close to the edge of the endless conveyor belt 200. Therefore, in this embodiment, guide strips 210 protruding from the outer surface of the endless conveyor belt 200 are provided on the endless conveyor belt 200, and the guide strips 210 are located on the opposite sides of the two baffle plates 300. In this way, even if a small amount of water and concrete overflow from the gap between the baffle plates 300 and the endless conveyor belt 200 to the side of the baffle plates 300 close to the edge of the endless conveyor belt 200, they can be blocked by the guide strips 210. It should be noted that the height of the guide strips 210 should not be too high to avoid tearing when the guide strips 210 pass through the redirecting roller 150 or the driving roller 140.

[0037] Referring to Figure 1 and Figure 2 As shown, in some embodiments of the present utility model, the two baffle plates 300 extend obliquely upward in a direction away from each other, that is, the inclined bottom ends of the two baffle plates 300 are located between the inclined top ends of the two baffle plates 300. It can be understood that if the baffle plate 300 is vertically arranged, that is, perpendicular to the annular conveyor belt 200 of the baffle plate 300, then after the baffle plate 300 receives the lateral force from the material on the annular conveyor belt 200, it is very easy to deform, resulting in a gap between the baffle plate 300 and the annular conveyor belt 200, causing material spillage. Therefore, in this embodiment, the two baffle plates 300 extend obliquely upward in a direction away from each other. In this way, when the material presses on the baffle plate 300, there will be a downward component force, enabling the baffle plate 300 to be in closer contact with the outer surface of the annular conveyor belt 200 and reducing the risk of material overflow.

[0038] Referring to Figure 1 and Figure 2 As shown, in some embodiments of the present utility model, the material of the baffle plate 300 is rubber. By setting rubber, rigid contact with the annular conveyor belt 200 can be avoided. On the one hand, it can reduce the wear on the annular conveyor belt 200. On the other hand, it also allows for a larger installation error of the baffle plate 300, and the cost of rubber is low, and the cost of maintenance and replacement is also low.

[0039] Referring to Figure 1 and Figure 2 As shown, in some embodiments of the present utility model, the baffle assembly further includes a mounting plate 310 and a clamping plate 320. The mounting plate 310 is fixed to the frame 100, and the clamping plate 320 is detachably connected to the mounting plate 310. The clamping plate 320 is used to cooperate with the mounting plate 310 to clamp and fix the baffle plate 300. By setting the clamping plate 320 and the mounting plate 310 to clamp and fix the baffle plate 300, the loss and replacement of the baffle plate 300 can be facilitated. Among them, the clamping plate 320 and the mounting plate 310 are detachably connected by bolts, which is convenient for disassembly and assembly.

[0040] Referring to Figure 1 and Figure 2As shown, in some embodiments of the present utility model, the belt conveyor for concrete of the present utility model embodiment further includes a support assembly. The support assembly includes a plurality of idlers 110 rotatably arranged on the frame 100. The plurality of idlers 110 are evenly spaced along the length direction of the endless conveyor belt 200. The idlers 110 are located on the lower side of the endless conveyor belt 200 in the conveying section. The idlers 110 are used to support the endless conveyor belt 200 to prevent the endless conveyor belt 200 from sagging due to the gravity of the material. Obviously, setting a plurality of idlers 110 to support the endless conveyor belt 200 can reduce the friction with the endless conveyor belt 200 and reduce the wear of the endless conveyor belt 200 compared with using a flat support structure, ensuring the service life of the endless conveyor belt 200.

[0041] Referring to Figure 1 and Figure 2 As shown, in some embodiments of the present utility model, a first limiting member 120 is provided between any two adjacent idlers 110 on the frame 100. The upper end surface of the first limiting member 120 is parallel to the endless conveyor belt 200. A first gap is provided in the vertical direction between the upper end surface of the first limiting member 120 and the inner surface of the endless conveyor belt 200. Obviously, compared with using a flat support structure to support the endless conveyor belt 200, although using idlers 110 can reduce the friction with the endless conveyor belt 200, the idlers 110 are cylindrical structures, and there will inevitably be a gap along the length direction of the endless conveyor belt 200 between two adjacent idlers 110. The endless conveyor belt 200 may sag at the gap between two adjacent idlers 110. Therefore, in this embodiment, a first limiting member 120 is provided between two adjacent idlers 110, so that the upper end surface of the first limiting member 120 is parallel to the inner surface of the endless conveyor belt 200 and a first gap is preset. In this way, even if the endless conveyor belt 200 sags, the endless conveyor belt 200 can be limited and supported by the first limiting member 120, greatly reducing the sagging degree of the endless conveyor belt 200. The setting of the first gap can avoid direct contact of the first limiting member 120 and reduce sliding friction.

[0042] In some specific embodiments, the first limiting member 120 is distributed along the width direction of the endless conveyor belt 200 to ensure its limiting effect.

[0043] In a further embodiment, first limiting members 120 are respectively provided with first arc surfaces 121 on opposite sides in the length direction of the annular conveyor belt 200. The first arc surfaces 121 extend to the edges of the upper end surfaces of the first limiting members 120. The first arc surfaces 121 are circumferentially distributed around the central axis of the adjacent idler 110. By providing the first arc surfaces 121, the area of the upper end surfaces of the first limiting members 120 can be expanded as much as possible, and the gaps between two adjacent idlers 110 in the length direction of the annular conveyor belt 200 can be filled as much as possible, so as to improve the limiting effect on the annular conveyor belt 200.

[0044] Referring Figure 1 and Figure 2 As shown in the figure, in some embodiments of the present utility model, second limiting members 130 are respectively provided on opposite sides in the length direction of the annular conveyor belt 200 of the support assembly, that is, all the idlers 110 are located between the two second limiting members 130. The second limiting members 130 are provided on the frame 100. The upper end surfaces of the second limiting members 130 are parallel to the annular conveyor belt 200, and a second gap is provided between the upper end surfaces of the second limiting members 130 and the inner surface of the annular conveyor belt 200. Similarly, by providing the second limiting members 130, the sag degree of the annular conveyor belt 200 can be reduced. Among them, one second limiting member 130 is located between the redirecting roller 150 and the adjacent idler 110, and the other second limiting member 130 is located between the driving roller 140 and the adjacent idler 110. The second limiting members 130 are respectively provided with second arc surfaces 131 on opposite sides in the length direction of the annular conveyor belt 200. The second arc surfaces 131 extend to the edges of the upper end surfaces of the second limiting members 130, and the idler 110 and the adjacent second arc surface 131 are coaxially distributed, the redirecting roller 150 and the adjacent second arc surface 131 are coaxially distributed, and the driving roller 140 and the adjacent second arc surface 131 are coaxially distributed. The principle is the same as that of the first arc surface 121, so it will not be described in detail here.
