Description

Technical Field

[0001] The utility model relates to the technical field of sand and gravel conveying, in particular to a sand and gravel raw material lifting conveyor. Background Technique

[0002] Conveyors are essential equipment for concrete production and processing enterprises. All kinds of sand and gravel raw materials need to be conveyed by conveyors. When the raw materials are transported to the workshop, the height of the general warehouse is relatively low, while the concrete processing equipment is relatively high. Therefore, the lifting conveyor comes in handy. In the workshop of concrete processing enterprises, it is common to see the use of lifting conveyors to transport raw materials such as sand and gravel. It can be said that the lifting conveyor is an important cornerstone for the operation of the concrete production workshop.

[0003] In most domestic concrete production workshops, the sanitary environment is relatively poor and difficult to improve. Reasons such as the transportation of various raw materials such as sand and gravel, the leakage of tap water transportation, the discharge of concrete, and the frequent entry and exit of transport vehicles will all cause the workshop floor environment and air environment to be unclean. The floor is wet, and there are various residual sand and gravel raw materials. The air is filled with powder, and it is difficult to solve the workshop environmental problems. However, for the needs of production and development, difficulties must be solved. For different problems, they should be improved one by one and overcome one by one.

[0004] During the process of the sand and gravel raw material lifting conveyor transporting sand and gravel raw materials, due to raw materials such as air humidity and sand and gravel raw material humidity, the sand and gravel raw material powder adhering to the conveyor belt after conveying and discharging is not cleaned up. During the continuous operation of the lifting conveyor, reasons such as the evaporation of the moisture of the sand and gravel raw material powder and the vibration of the conveyor belt will cause the sand and gravel raw material powder to escape into the workshop air environment and settle on the workshop floor. Some existing conveyors clean the surface of the conveyor belt by setting a scraper under the belt surface. Due to the fast conveying speed of the conveyor belt, the low tension of the lower belt surface, and the condensation of some sand and gravel raw materials, it is difficult to clean the attached sand and gravel raw materials, and the powder cleaned up is not collected in time, which will also cause secondary pollution to the workshop air environment. In order to solve the workshop environmental pollution problem caused by the sand and gravel raw material lifting conveyor, a new type of sand and gravel raw material lifting conveyor is proposed.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-4 shown, the present utility model provides a technical solution: a sand and gravel raw material lifting conveyor, including a conveyor belt 1, the conveyor belt 1 includes a horizontal feeding end section 101, an inclined climbing section 102 and a horizontal blanking section 103, and support rollers 13 are provided on both sides of the horizontal feeding end section 101, the inclined climbing section 102 and the horizontal blanking section 103 of the conveyor belt 1 to support the lower sides of the upper belt surface;

[0023] A support frame 2 is fixedly welded on the conveyor frame below the horizontal blanking section 103. A collection box 3 and two groups of symmetrically arranged adjustable lifting frames 5 fixedly connected to both sides of the collection box 3 are respectively placed on the support frame 2. Dust shields 4 are installed on the tops of the collection box 3 corresponding to the upstream and downstream positions of the conveyor belt 1. Vertical connection grooves 401 are provided on both sides of the dust shield 4, and the dust shield 4 is movably installed on the collection box 3 through the connection grooves 401 and bolts;

[0024] There is a movable rod 6 horizontally movably connected between two groups of adjustable lifting frames 5. An expansion and reciprocating motor 7 is installed on the adjustable lifting frame 5 and is drivingly connected to one end of the movable rod 6. A dust removal brush 8 in contact with the lower belt surface of the horizontal feeding section 103 is installed on the movable rod 6. A connecting arm 9 is fixedly connected to the top of one side of the adjustable lifting frame 5. A spring telescopic rod 10 is vertically installed on the connecting arm 9. The top of the spring telescopic rod 10 is installed with a scraping plate 11 in contact with the lower belt surface of the horizontal feeding section 103 through a mounting seat 12;

[0025] The scraping plate 11 is located on the downstream side of the dust removal brush 8. Both between the mounting seat 12 and the scraping plate 11 and between the movable rod 6 and the dust removal brush 8 are fixedly installed by bolts. The dust shield 4 is U-shaped, and both the scraping plate 11 and the dust removal brush 8 are located between the two dust shields 4. The vertical length of the connecting groove 401 is greater than the distance between the bottom of the spring telescopic rod 10 and the lower belt surface of the horizontal feeding section 103.

[0026] Working principle:

[0027] The spring telescopic rod 10 supports the scraping plate 11 to contact the lower belt surface of the conveyor belt 1. The spring telescopic rod 10 can be telescopic, effectively avoiding damage to the conveyor belt 1. The scraping plate 11 initially cleans the sand and gravel raw material powder on the lower belt surface of the horizontal feeding section 103. At the same time, the expansion and reciprocating motor 7 drives the dust removal brush 8 through the movable rod 6 to clean the remaining sand and gravel raw material powder on the lower belt surface of the horizontal feeding section 103. Both the scraping plate 11 and the dust removal brush 8 are arranged for the horizontal feeding section 103 and are cleaned immediately after feeding, and the cleaning is relatively timely. The sand and gravel raw material powder cleaned is collected by the collection box 3. The dust shield 4 blocks the sand and gravel raw material powder cleaned, avoiding dust generation and reducing the environmental pollution of the workshop air and the bottom surface.
