Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand and gravel production technology, and in particular to a construction sand and gravel transfer machine. Background Technology
[0002] Construction sites require a large amount of sand and gravel when preparing concrete. The existing sand and gravel are usually in the river. The dredged sand and gravel are usually transferred multiple times using the bucket of a crane. After the sand and gravel aggregate is taken out, it needs to be transported by belt conveyor and then washed, dried, crushed and other operations.
[0003] Because the belt conveyor is set up in parallel and has a certain height, it needs to be set up with an inclined conveyor belt to transfer the sand and gravel that has just been dredged from the river to a higher place. However, there is a lot of silt in the river. The silt and sand and gravel are mixed together and will stick to the surface of the conveyor belt, making it impossible to discharge the material all at once. In addition, because the conveyor belt is set up with an inclination, the material is prone to slipping during the conveying process. Utility Model Content
[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing a construction sand and gravel transfer machine.
[0005] The technical solution of this utility model is a construction sand and gravel transfer machine, comprising:

[0022] Example 1
[0023] like Figures 1-3 As shown in the figure, the construction sand and gravel transfer machine proposed in this embodiment includes a base 3, a transmission belt 2 and a scraper 9.
[0024] A frame 1 is rotatably mounted on one end of the base 3. A first linear drive mechanism 5 for driving the frame 1 to rotate is rotatably mounted on the base 3. The output shaft of the first linear drive mechanism 5 is rotatably connected to the side of the frame 1.
[0025] The transmission belt 2 is mounted on the frame 1. The frame 1 is equipped with a first power assembly for driving the transmission belt 2. The first power assembly includes a first servo motor 13 and multiple transmission rollers. The multiple transmission rollers are mounted side by side and rotate on the frame 1. The transmission belt 2 is sleeved on the outer periphery of the multiple transmission rollers. One or more first servo motors 13 are provided. The first servo motor 13 is mounted on the frame 1 and its output shaft is connected to the rotating shaft of the corresponding transmission roller. The rotating shaft of the transmission roller is fixedly connected to the transmission roller, while the rotating shaft of the transmission roller is rotatably mounted on the frame 1. The rotating shaft of the transmission roller and the output shaft of the first servo motor 13 are connected by a coupling. Multiple lifting plates 10 are mounted on the outer surface of the transmission belt 2.
[0026] An upper end plate 4 is provided above the transmission belt 2. The upper end plate 4 is parallel to the upper part of the transmission belt 2 and is mounted on the frame 1. When the material moves to the position below the upper end plate 4, the material is limited below the upper end plate 4, which can prevent the material from slipping.
[0027] Side guards 11 are provided on both sides of the transmission belt 2 along its circumference. The side guards 11 are made of rubber material and are provided to prevent material from overflowing from the side of the transmission belt 2.
[0028] The scraper 9 contacts the bottom surface of the conveying end of the transmission belt 2. A connecting frame 12 is connected to the scraper 9. An elastic connecting assembly is connected between the connecting frame 12 and the frame 1. The elastic connecting assembly includes a guide rod 19, a spring 20, and a limiting block 21. The guide rod 19 is vertically arranged on the side wall of the frame 1 and passes through the end of the connecting frame 12. The limiting block 21 is located at the end of the guide rod 19, and the spring 20 is sleeved on the guide rod 19.
[0029] Specifically, the equipment is moved to the vicinity of the river. To facilitate the movement of the equipment, multiple self-locking casters 7 are installed at the bottom of the base 3. The first linear drive mechanism 5 is activated to drive the frame 1 to rotate, so that the upper end of the transmission belt 2 rotates to a position above the feeding start end of the belt conveyor.
[0030] Workers load the sand and gravel dredged from the river onto the transmission belt 2, and start the first servo motor 13 to drive the transmission roller shaft to rotate. The rotation of the transmission roller shaft drives the transmission roller to rotate, which in turn drives the transmission belt 2 to move, thereby realizing the conveying of materials. The multiple lifting plates 10 in the technical solution are set to prevent the materials on the transmission belt 2 from sliding down. However, the sand and gravel freshly dredged from the river will carry mud, which will cause the mud and sand to stick to the surface of the transmission belt 2, making the discharge difficult. Therefore, the technical solution is equipped with a scraper 9, which can scrape off the silt and impurities on the surface of the transmission belt 2. The elastic connecting component allows the scraper 9 to move downward adaptively when the lifting plate 10 passes by the scraper 9, so that the lifting plate 10 can pass smoothly through the scraper 9 position. The scraper 9 can also scrape off the silt on the surface of the lifting plate 10. It should be added that the cross-section of the lifting plate 10 is a triangular structure, and the pointed part of the lifting plate 10 is chamfered. This design helps to improve the stability of the lifting plate 10 when passing by the scraper 9.
[0031] Example 2
[0032] like Figure 1 As shown, this embodiment of the construction sand and gravel transfer machine, compared with the first embodiment, has a discharge plate 17 below the transmission belt 2, and sliding seats 16 are slidably installed on both sides of the frame 1. A second power assembly for driving the sliding seats 16 to move is installed on the frame 1. The second power assembly includes a second servo motor 14 and a threaded rod 15. The second servo motor 14 is installed on the frame 1, and the threaded rod 15 is connected to the output shaft of the second servo motor 14. The sliding seats 16 are threadedly connected to the threaded rod 15. One end of the discharge plate 17 is connected to two rotating connecting plates 18, which are rotatably connected to the sliding seats 16 on both sides. A second linear drive mechanism 6 is rotatably installed on the sliding seats 16. The output shaft of the driving mechanism 6 is rotatably connected to the discharge plate 17. The first linear drive mechanism 5 and the second linear drive mechanism 6 in the technical solution are one of the following driving components: cylinder, hydraulic cylinder and electric push rod. In actual operation, when the conveying distance of the transmission belt 2 is insufficient, the sliding seat 16 can be moved to the feeding end of the transmission belt 2 by the second power component. The movement of the sliding seat 16 drives the rotating connecting plate 18 and the discharge plate 17 to move. Then, the discharge plate 17 is driven to rotate by the second linear drive mechanism 6, so that the transmission belt 2 and the discharge plate 17 form an inverted "V" shape. The material output by the transmission belt 2 will fall on the discharge plate 17 and slide down the inclined surface of the discharge plate 17 onto the belt conveyor, thereby improving the feeding range of the equipment.
[0033] It should be added that before driving the discharge plate 17 to reset, the discharge plate 17 needs to be driven to be parallel to the transmission belt 2. Then drive the discharge plate 17 to reset, and the sludge on the upper surface of the discharge plate 17 can be scraped off by the connecting frame 12.
[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
