[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-2 A sand and gravel feeding device for a concrete mixing station comprises a storage bin 2 for containing sand and gravel and a feeding box 3 for feeding sand and gravel, wherein the feeding box 3 is installed below the storage bin 2 through a bracket 1, and the storage bin 2 is installed above the feeding box 3, so that the sand and gravel in the storage bin 2 can automatically fall under the action of its own gravity, so that the sand and gravel can be moved into the feeding box 3 without external force driving;

[0022] In order to better realize the movement of sand and gravel from the storage bin 2 to the feed box 3, a feed port is provided at the top of the feed box 3, and the feed port is connected with the bottom of the storage bin 2 through a feed pipe 4. A feed control valve 5 is installed on the feed pipe 4, and the feed control valve 5 is used to control the switch of the feed pipe 4, so as to realize the feeding control of sand and gravel;

[0023] In order to realize the external output of the sand and gravel in the feeding box 3, at least two feeding ports are arranged at the bottom of the feeding box 3, each feeding port is connected to a feeding pipe 6, and a feeding control valve 7 is installed on the feeding pipe 6. The number of feeding pipes 6 and feeding ports is the same, and multiple feeding ports are arranged, which is convenient for feeding operations to multiple devices to better meet different usage requirements. The feeding control valve 7 is used to control the switch of the feeding pipe 6, which is convenient for realizing the feeding control of sand and gravel;

[0024] Specifically, a feeding barrel 8 for cooperating with the feed port and the feed opening is installed in the feeding box 3. The feeding barrel 8 is vertically installed on the feeding box 3 through a support shaft. A feeding adjustment driving device 9 is also installed on the feeding box 3 for driving the feeding barrel 8 to tilt and swing left and right to achieve the coordination of the feed port with different feeding ports. Support shafts are fixedly installed on both sides of the feeding barrel 8. The support shafts are installed on the feeding box 3 through bearings and bearing seats. One of the support shafts penetrates the feeding box 3 and extends to the outside of the feeding box 3 to facilitate the coordination with the feeding adjustment driving device 9. The feeding barrel 8 is arranged in the feeding box 3, and is used for diverting the sand and gravel entering the feeding box 3 through the feeding port. The sand and gravel can be guided as needed to be output outward from different feeding ports to achieve feeding adjustment of the sand and gravel; the feeding adjustment driving device 9 is used to provide power for the position adjustment of the feeding barrel 8; in order to achieve better coordination between the feeding barrel 8 and the feeding port, a material guiding hose 11 is also connected between the feeding port and the top opening of the feeding barrel 8. The setting of the material guiding hose 11 can enable the feeding barrel 8 to always be connected to the feeding port without affecting the relative displacement operation of the feeding barrel 8 and the feeding port.

[0025] Preferably, there are three feeding ports, which are arranged side by side horizontally at the bottom of the feeding box 3. In order to avoid mutual influence between adjacent feeding ports, a partition plate 10 is fixedly installed on the feeding box 3 between the feeding ports.

[0026] Preferably, the feeding adjustment driving device 9 is an electric push rod, and a transmission gear 12 is installed on the support shaft on the feeding barrel 8, and a transmission rack 13 cooperating with the transmission gear 12 is installed on the push rod end of the electric push rod, so that the electric push rod can be used to drive the transmission rack 13 to move back and forth, so as to drive the supporting shaft through the transmission gear 12 to drive the feeding barrel 8 to swing left and right, and the transmission rack 13 is arranged above the transmission gear 12; further preferably, a slider 15 is installed on the transmission rack 13, and a slide groove 16 cooperating with the slider 15 is also installed on the feeding box 3. When the transmission rack 13 moves back and forth, the slider 15 moves back and forth in the slide groove 16, which can assist the movement of the transmission rack 13 and prevent it from running off.

[0027] In order to perform fixing operation after the feeding barrel 8 is adjusted into place, a limit screw 14 is screwed onto the transmission rack 13, and a plurality of limit holes 17 cooperating with the limit screw 14 are provided on the feeding box 3. After the feeding barrel 8 is adjusted into place, the limit screw 14 is rotated so that the threaded end thereof is inserted into the limit hole 17 to realize the limit operation.

[0028] In actual application, both the feed control valve 5 and the feed control valve 7 are designed to be electrically operated, which makes the switch action faster and more convenient; in addition, the design of the storage bin 2 is also unique, with a cylindrical shape on the upper part and a funnel-shaped design on the lower part. Such a design is not only conducive to the storage of materials, but also ensures that the materials can flow out smoothly. At the same time, the feed box 3 is designed to be a rectangular parallelepiped, which is convenient for the stability of its structure and the rational use of space, while the feed barrel 8 is cylindrical, and the two ends of the feed barrel 8 are funnel-shaped. Such an overall design not only improves the operating efficiency of the equipment, but also optimizes the structure of the equipment, making it easier to design, manufacture, install and use.

[0029] The use process of the sand and gravel feeding device of the concrete mixing station provided in this application is as follows:

[0030] Before use, the sand and gravel are first placed in the storage bin 2, and then a screw conveyor is installed at the output end of each feeding pipe 6, so that the sand and gravel output through the feeding pipe 6 can be delivered to the equipment requiring sand and gravel feeding by the screw conveyor;

[0031] When in use, first select the feeding pipe 6 according to the sand and gravel feeding needs, and use the feeding adjustment driving device 9 to drive the feeding barrel 8 to swing, so that the bottom end of the feeding barrel 8 swings to the top of the feeding port corresponding to the selected feeding pipe 6, then open the feeding control valve 5 and the feeding control valve 7, so that the sand and gravel in the storage bin 2 are input into the feeding box 3 through the feeding port, and then guided to the corresponding feeding pipe 6 through the feeding barrel 8, and finally transported to the equipment that needs sand and gravel feeding through the corresponding screw conveyor;

[0032] When it is necessary to adjust the sand and gravel feeding, first close the feed control valve 5 and the feed control valve 7 to stop the sand and gravel feeding, and then use the feed adjustment drive device 9 to drive the feeding barrel 8 to swing, so that the bottom end of the feeding barrel 8 swings to just above the feeding port corresponding to the selected feeding pipe 6, and then open the feed control valve 5 and the feeding control valve 7 to continue the feeding operation.
