[0015] The working principle and beneficial effects of the utility model are:

[0016] 1. In the utility model, when concrete is fed to the top of the connecting plate, the connecting plate will begin to sink, and the connecting plate will synchronously drive the sliding plate to move downward during the sinking process, and the sliding plate will synchronously drive the spring to compress downward during the movement, and the positioning plate will limit the concrete during this process.

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments 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.

[0025] Example 1

[0026] like Figure 1~Figure 4 As shown, this embodiment proposes a quantitative feeder for the production of autoclaved aerated concrete blocks, including a conveyor belt 1, a card plate 2 is fixedly connected to one side of the top of the conveyor belt 1, a motor 3 is fixedly connected to one side of the outside of the card plate 2, the motor 3 is fixedly connected to a rotating rod 4 through an output shaft, the rotating rod 4 is fixedly connected to a rotating shell 6 on the outside, sliding grooves are provided on both sides of the inside of the rotating shell 6, springs 7 are fixedly connected to the inside of the two sliding grooves, sliding plates 8 are fixedly connected to the tops of the two springs 7, a connecting plate 9 is fixedly connected between the two sliding plates 8, positioning plates 10 are fixedly connected to both sides of the top of the connecting plate 9, a touch switch 11 is fixedly connected to the bottom of the inner cavity of the rotating shell 6, and the touch switch 11 is electrically connected to the motor 3.

[0027] In this embodiment, the outsides of the two sliding plates 8 are in contact with the insides of the two sliding grooves respectively, and the rotating rod 4 extends into the inside of the card plate 2 and is connected to the card plate 2 through a bearing, which can facilitate the support work of the rotating rod 4.

[0028] When it is necessary to feed concrete, first the staff needs to connect the device with the external feeding equipment, that is, the connecting plate 9 is located at the bottom of the feeding place. When the concrete is fed to the top of the connecting plate 9, the connecting plate 9 will begin to sink. During the sinking process, the connecting plate 9 will synchronously drive the sliding plate 8 to move downward. During the movement, the sliding plate 8 will synchronously drive the spring 7 to compress downward. During this process, the positioning plate 10 will limit the concrete. If the connecting plate 9 drops to a state of contact with the touch switch 11, the touch switch 11 will control the motor 3 to turn on. After turning on, the motor 3 will synchronously drive the rotating rod 4 to rotate. During the rotation process, the rotating rod 4 will synchronously drive the rotating shell 6 to rotate and tilt. During the rotation process, the rotating shell 6 will synchronously drive the concrete to tilt, so as to facilitate the dumping and discharge of the concrete, thereby ensuring the automated working effect.

[0029] Example 2

[0030] like Figure 2~Figure 3 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that two round shells 12 are fixedly connected on both sides of the outside of the rotating shell 6, and elastic springs 13 are fixedly connected inside the four round shells 12, which can facilitate the fixing work of the round shells 12 to the elastic springs 13.

[0031] In this embodiment, the four elastic springs 13 are all in an unstretched state, and the outer ends of the four elastic springs 13 are fixedly connected with the sliding column 14, so that the elastic springs 13 can drive the sliding column 14 to move.

[0032] In this embodiment, the outer surface of the slide column 14 is in contact with the inside of the round shell 12, and the bottom of the conveyor belt 1 is fixedly connected with the bottom plate 5, which can facilitate the bottom connection of the conveyor belt 1.

[0033] In this embodiment, a fixing plate 15 is disposed outside the two sliding columns 14 , and one side of the fixing plate 15 is fixedly connected to one end of the two sliding columns 14 , which can facilitate the fixed connection of the sliding columns 14 .

[0034] In this embodiment, the cross section of the fixing plate 15 is configured to be in a zigzag shape, and one side of the fixing plate 15 is fixedly connected to the limiting plate 16 , which can facilitate the fixing of the limiting plate 16 .

[0035] In this embodiment, the limiting plate 16 is located at the front side of the rotating shell 6, and the cross section of the limiting plate 16 is set to be triangular, which can facilitate the limiting work of the limiting plate 16.

[0036] Since the concrete itself is heavy, when the concrete tilts, the limit plate 16 will first contact the concrete and limit it. If the rotating shell 6 drives the concrete to tilt to an angle close to ninety degrees, the weight of the concrete is extremely large at this time, and it will squeeze the inclined surface of the limit plate 16 through its own edges and corners. During the squeezing process, the limit plate 16 will simultaneously drive the fixed plate 15 and the sliding column 14 to move. During this process, the elastic spring 13 will be stretched, and then the concrete will automatically fall on the top of the conveyor belt 1, thereby achieving the effect of discharging and protecting the concrete and preventing the concrete from falling at a higher state and causing surface damage.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
