[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The object of the present invention is to provide a feeding device to solve the technical problem that the existing feeding device cannot achieve quantitative feeding and has high transmission efficiency.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 As shown, the present invention provides a feeding device, including a shell 1, a material tray 5 and a driving component. The upper end of the shell 1 is provided with a feeding port, and the material is concentrated in the shell 1 and distributed through the feeding device to control the material. The material tray 5 is arranged in the shell 1 and close to the lower end of the shell 1. The material enters the shell 1 through the feeding port and reaches the material tray 5. An adjusting component is provided at the feeding port. The adjusting component can adjust the amount of material falling onto the material tray 5 through the feeding port, so as to control the discharge amount by changing the amount of material entering the shell 1, and realize quantitative feeding. The driving component is used to drive the material tray 5 to rotate, and can adjust the material tray 5 when the material tray 5 rotates. During the movement, the material on the tray 5 moves away from the center of the tray 5 due to the centrifugal force to facilitate the discharge of the material. At the same time, when the driving component drives the tray 5 to rotate, the transmission power is reduced due to the small amount of material on the tray 5, which effectively saves energy. A discharge port is provided on the side wall of the shell 1, and the discharge port is arranged close to the tray 5. The outer edge of the tray 5 extends to the inner wall of the shell 1 to prevent the material from falling from the gap between the tray 5 and the inner wall of the shell 1, affecting the material discharge efficiency. When the tray 5 rotates, the material on the tray 5 can rotate to be discharged through the discharge port, thereby realizing quantitative feeding.

[0024] Specifically, the regulating component includes a material collector 2 and a regulating pipe 3. The material collector 2 and the regulating pipe 3 are internally connected, and the upper end of the material collector 2 is open. The upper end of the material collector 2 is fixed to the lower end of the feed port. The material collector 2 is used to receive the material to ensure that all the material passing through the feed port enters the material collector 2, and the material collector 2 is used as a temporary storage place for the material, so that the weight of the material is concentrated on the material collector 2, reducing the weight of the material on the material tray 5, and the material collector 2 does not need to move or rotate, reducing the transmission power and reducing energy consumption. The lower end of the material collector 2 is connected to the upper end of the regulating pipe 3, and the lower end of the regulating pipe 3 The regulating pipe 3 is closed, and a connecting port is provided on the side wall of the regulating pipe 3.

The connecting port is arranged near the lower end of the regulating pipe 3, and the side wall of the communicating port near the material tray 5 is flush with the inner bottom surface of the regulating pipe 3, to ensure that all the material in the regulating pipe 3 can be discharged through the connecting port, to prevent the material from being piled up in the regulating pipe 3 and affecting the discharge efficiency of the material, and a baffle 4 is detachably fixed at the position of the regulating pipe 3 corresponding to the connecting port, the baffle 4 is used to adjust the opening of the connecting port, and the opening of the connecting port is changed by changing the shielding area of ​​the baffle 4 on the connecting port, thereby changing the amount of material discharged through the connecting port to realize quantitative feeding.

[0025] The material collector 2 is conical, and its diameter gradually decreases from top to bottom. The outer wall of the upper end of the material collector 2 fits with the inner wall of the shell 1, which facilitates the downward movement of the material in the material collector 2.

[0026] The axis of the regulating tube 3 coincides with the axis of the material tray 5, and the connecting port is arranged on the side of the regulating tube 3 away from the discharge port, so as to ensure that the material falls into the side of the material tray 5 away from the discharge port after being discharged through the discharge port, so that during the rotation of the material tray 5, the material can move to the edge of the material tray 5 to the feed port under the action of centrifugal force. The baffle 4 is provided with a long hole, and the length direction of the long hole is consistent with the length direction of the regulating tube 3. The regulating tube 3 is provided with a threaded hole, and the threaded hole is located above the connecting port. The baffle 4 is connected to the regulating tube 3 by bolts passing through the long hole and the threaded hole in turn, and the height of the baffle 4 from the material tray 5 is adjustable, so as to adjust the opening of the connecting port and realize quantitative feeding.

[0027] A hand hole 7 is provided on the side wall of the shell 1 at a position corresponding to the baffle 4. The hand hole 7 can connect the inner cavity of the shell 1 with the outside.

[0028] A scraper plate 6 is provided at the discharge port, one end of the scraper plate 6 is fixed on one side of the discharge port, and the other end extends toward the center of the material tray 5, and the scraper plate 6 is used to prevent the material from moving in the direction away from the discharge port, thereby ensuring that the material can be discharged through the discharge port and preventing the material from rotating to the hand hole 7 and affecting the discharge of the material. It can be understood that the scraper plate 6 is fixed on the side of the discharge port close to the rotation direction of the turntable, that is, when the material rotates, it first passes through one side of the discharge port, and the scraper plate 6 is fixed on the other side of the discharge port. The material is blocked by the scraper plate 6 and discharged from the discharge port.

[0029] A discharge pipe 8 is provided at the discharge port, one end of which is fixed at the discharge port, and the other end extends away from the shell 1. The discharge pipe 8 can connect the inner cavity of the shell 1 with the outside world, and the discharge pipe 8 plays a guiding role for the material.

However, in the feeding device provided by the present invention, the specific structure of the driving assembly is not limited to the above limitation, as long as the stable driving of the material tray 5 can be achieved.

[0031] The transmission shaft 10 is connected to the material tray 5 by bolts, which ensures the stability of the material tray 5 when it rotates, and is easy to disassemble and clean.
