DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more understandable, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from this description, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0030] like Figure 1-Figure 5 As shown, the present invention discloses an aggregate bin bucket door, which comprises: a door body 1, the door body 1 is equipped with a bucket door assembly 4 and an inner bucket 10, the bucket door assembly 4 comprises: a transmission arm 40, a rotating shaft 41 and a bucket door 42, the rotating shaft 41 is rotatably mounted on the door body 1, the outer end of the rotating shaft 41 is fixedly connected to the transmission arm 40, the inner end of the rotating shaft 41 is fixedly connected to the bucket door 42, the inner bucket 10 is arranged at the feeding end of the door body 1 and is used to guide the fed aggregate, the bucket door 42 is used to control the discharge of the inner bucket 10, and the bucket door 42 and the inner bucket 10 are both arranged in the door body 1;

[0031] Combination Figure 1 , Figure 2 As shown, a driving device 3 is installed on one side of the door body 1, and the driving device 3 is provided with a power source 30. The transmission arm 40 is connected to the power source 30, and the power source 30 drives the transmission arm 40 to rotate;

[0032] Combination Figure 1-Figure 4 As shown, the door body 1 is equipped with a proximity sensor 6, which is arranged on the rotation path of the transmission arm 40, and the positions of the two proximity sensors 6 correspond to the open state and the closed state of the bucket door 42 respectively;

[0033] Combination Figure 3-Figure 5 As shown, a discharge hopper 11 is installed at the discharge end of the door body 1, and a receiving hopper 7 is provided at the lower end of the discharge hopper 11, and the discharge hopper 11 guides the aggregate into the receiving hopper 7;

[0034] A sealing member 8 is installed at the discharge end of the door body 1 , and the sealing member 8 surrounds and seals the outlet of the discharge hopper 11 and the inlet of the receiving hopper 7 .

[0035] It should be pointed out that, in some usage scenarios, in order to ensure that the discharge hopper 22 is unlikely to cause the receiving hopper 7 to shake, the sealing member 8 is a flexible rubber.

[0036] It should be noted that the transmission arm 40 will block the proximity sensor 6 when rotating. At this time, the proximity sensor 6 will output a corresponding detection signal.

[0037] Specifically, the power source 30 is any one of a cylinder assembly, a motor, and a linear drive assembly. When a motor is used for rotational drive, a corresponding reducer is also required. Figure 1 , Figure 2 As shown, when the power source 30 is a cylinder assembly, the driving device is provided with a fixed bracket, the fixed bracket is fixedly connected to the door body 1, one end of the cylinder assembly is rotatably connected to the fixed bracket, and the other end is rotatably connected to the transmission arm 40.

[0038] Combination Figure 3 As shown, a limiting component 5 is installed on the door body 1, and the limiting component 5 is used to limit the rotation of the transmission arm 40 to prevent the transmission arm 40 from rotating beyond the range, thereby preventing the bucket door 42 from hitting the inner wall of the door body 1 or the inner bucket 10.

[0039] Specifically, combined Figure 4 As shown, the bucket door 42 includes: a swing arm 420 and a hopper 421, one end of the swing arm 420 is fixedly connected to the rotating shaft 41, and the other end of the swing arm 420 is fixedly connected to the hopper 421;

[0040] In the closed state, the hopper 421 completely blocks the discharge port of the inner bucket 10, and in the open state, the hopper 421 partially blocks or completely blocks the discharge port of the inner bucket 10;

[0041] In some scenarios, there is a residual gap between the hopper 421 and the discharge port of the inner hopper 10, and after the aggregate fills the hopper 421, it can overflow from the residual gap into the discharge hopper 11.

[0042] Specifically, combined Figure 1-Figure 3 As shown, it also includes: a rod valve 2, which is electric or manual, and is installed at the feeding end of the door body 1 and located on the upper side of the inner bucket 10, and the rod valve 2 is used to control the feeding of the door body 1;

[0043] When the rod valve 2 is manual, the driving device 3 is provided with a bracket 31, and the bracket 31 is used to place the rod 32 of the rod valve 2. The feed port 20 of the rod valve 2 corresponds to the feed port of the door body 1. A plurality of valve ports 21 are provided on the side of the rod valve 2, and the valve ports 21 are used for inserting the rod 32. When the rod 32 is not inserted, the valve ports 21 are blocked by valve plugs 22. The insertion amount and position of the rod 32 are adjusted to control the amount and position of the aggregate. The electric rod valve is a prior art, and its structure is not described in detail here.

[0044] Combination Figure 4 As shown, the discharge port of the inner bucket 10 is on the lower side of the rotating shaft 41, and the aggregate is directly guided by the inner bucket 10 to the hopper 421 of the hopper door 42, which not only reduces dust emission but also protects the rotating shaft 41, and can prevent aggregate and dust from directly colliding with the connection between the rotating shaft 41 and the swing arm 420. In addition, the side of the hopper 421 facing the inner bucket 10 is concave.

[0045] Specifically, at least one proximity sensor 6 is provided to detect the unloading position of the hopper 42, that is, two proximity sensors 6 correspond to the open state and the closed state of the hopper 42, and at least one proximity sensor 6 corresponds to the unloading position of the hopper 42. Different unloading positions correspond to different opening angles of the hopper 42, thereby realizing the control of the amount of aggregate put in. Figure 5 As shown, the bucket door 42 is in a closed state when it is facing the discharge port of the inner bucket 10, and it is in an open state when the bucket door 42A is located on one side of the discharge port of the inner bucket 10. The opening angle range of the bucket door between the closed state and the open state is the setting range of the unloading gear.

[0046] Furthermore, it also includes: a controller, which is electrically connected to the driving device 3 and the proximity sensor 6, and is used to control the feeding of aggregate. The controller controls the rotation of the bucket door by controlling the driving device, during which the position of the bucket door is obtained through the proximity sensor, and then the opening and closing of the driving device is controlled in a timely manner, and finally the purpose of controlling the feeding of aggregate is achieved. Similarly, if the rod valve is electric, it is also electrically connected to the controller, and the controller controls the opening amplitude of the electric rod valve, thereby controlling the feeding amount of aggregate.

[0047] In summary, by building an inner bucket and bucket door into the door body, and using seals to seal and connect the openings of the discharge hopper and the receiving hopper, the working environment of the bucket door of the aggregate silo is fully sealed, so that when the aggregate is discharged, the pollution caused by dust can be greatly reduced; the bucket door is driven to rotate by the driving device to control the discharge of aggregate, and the current rotation position of the bucket door is obtained in conjunction with the proximity sensor, so as to control the discharge of the aggregate silo in real time, and the automatic delivery of aggregates to the aggregate silo can be realized by adjusting the number of proximity sensors and the access controller.

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
