The bottom of the storage bin is conical, so that the materials can be promoted to slide to the bottom. As a configuration mode, a material smashing device can be arranged in the material bin, so that materials are loosened and can be more easily and smoothly discharged.
A feeding device such as a vibrating feeder 9 arranged on the fixed support 3 is arranged in a manner of matching with natural blanking, and a material bearing structure such as a vibrating screen of the vibrating feeder 9 is positioned below the blanking port and can bear materials falling from the blanking port; the material thus dropped from the drop opening will be fed by the vibrating feeder 9 constantly, and when the vibrating feeder 9 stops working, the material will slowly build up if no other processing is performed. In certain implementations, other types of feed devices, such as screw conveyors, can be used to transport material in auger fashion.
The regulating valve assembly is arranged in a matched manner and is positioned at the blanking port, and the regulating valve assembly is attached to the storage bin 1 and can regulate the opening size of the blanking port; the illustrated regulator valve assembly is in the form of a gate valve, which will be described in detail below. Alternatively, the movement track of the inserting plate can be linear or arc-shaped, for example, the edge of the inserting plate is rotatably connected with the storage bin, and then the position of the inserting plate can be changed through rotation to cover the blanking port to different degrees.
As an arrangement for monitoring the weight change of the material, a weighing device 2 is provided in the figure, which weighing device 2 is attached to the silo 1 and is capable of detecting the weight change of the silo 1 and its contents.

As an alternative implementation, a change in weight may also be detected by using a suspension tension meter to detect a change in the weight of the bin.
As a more convenient time-limited manner, a control device 18 is also included, the control device 18 being electrically connected to the weighing device 2; the control device 2 is arranged to receive the information data sent by the weighing device 2 and control the regulating valve assembly to regulate the opening size of the blanking port according to the information data. It should be noted that, in an exemplary implementation manner, a weighing device, such as a weighing sensor, is set to send a signal (a wireless signal or a wired signal) carrying information data after a detected value reaches a certain threshold, and the control device triggers and executes an operation of sending a control instruction after receiving the signal, which can be implemented by a common control circuit or a commercially available controller loading a control program, so that only a mechanism for executing the control idea is introduced, and details of a specific control device are not described. The control device sends a command to control the regulating valve assembly to perform corresponding operations, which is also known to the skilled person and will not be described in detail. The various control mechanisms introduced in this specification can be loaded in the main control device of the existing feeding equipment, such as an industrial personal computer, a control cabinet and the like.
More specifically, the control mechanism will include: the weighing equipment, for example the load cell 2, is arranged to send first information data to the control device 18 when the reduced weight of the silo 1 and its contents reaches a first threshold value; when the reduced weight of the silo 1 and its contents reaches a second threshold value, second information data are sent to the control device 18; wherein the first threshold is less than the second threshold;
correspondingly, the control device 18 is configured to, upon receiving the first information data, control the regulating valve assembly to regulate the opening of the blanking opening from a first opening size to a second opening size smaller than the first opening size; and receiving the second information data, and controlling the regulating valve assembly to seal the blanking port.

and a driving means such as a cylinder 5 for driving the valve plate 8 to move along the valve plate guide 6.
Thus, the automatic driving control can be realized by a mechanical structure. The valve member of the inserting plate structure can cut off the conveying of the materials more easily. Alternatively, a butterfly valve structure may be provided as the regulating valve extending from the blanking opening.
As shown, the driving device adopts an air cylinder, and in an implementation mode not shown in the figure, a hydraulic cylinder, an electric cylinder and a screw conveyer can also be used as the driving device to push the valve plate to move along the valve plate guide rail.
As a means for controlling the size change of the blanking opening, a first position sensor is arranged on the valve plate 8 and/or the valve plate guide rail 6, the first position sensor is set to send braking information data to the control device when the regulating valve assembly regulates the opening of the blanking opening from a first opening size to a second opening size smaller than the first opening size, and the control device brakes the driving device when receiving the braking information data. The relative movement of the valve plate and the valve plate guide rail is sensed through a position sensor, particularly when the valve plate moves to a specified position, the opening size of the blanking port meets a preset requirement at the position, at the moment, the position sensor is set to transmit and carry brake specified data (wireless data or wired data) to be received by a control device, and the control device operates a driving device to stop driving the valve plate by taking the brake specified data as a trigger. The valve plate is fixed at a desired position, and the driving device can also prevent the sliding and displacement of the valve plate through self-locking.
In a further preferred implementation, the weighing and feeding device further comprises a material blocking device, and the material blocking device is arranged to be capable of sealing the discharge hole of the feeding device. Therefore, after the blanking port is closed, excessive feeding caused by flash generated in the stopping process of feeding devices such as a vibrating feeder can be reduced.

That is to say, when adjusting blanking mouth size, the material that keeps off the material simultaneously also reduces the material flow of feeder's discharge gate, and whole material flow tends to the homogeneity to through the synchronous reduction of blanking mouth with the export material, more do benefit to the accurate control who realizes the feed measurement. And double truncation or adjustment can be formed, and a small error in the adjustment of one of the blanking port link and the discharging port link can be corrected by the other link, so that the material flow is ensured to be kept in a preset range.

The swing support 11 and the fixed end of the telescopic device 12 are rotatably connected with the swing support 11, so as to form a typical swing link structure, the angle of the striker plate is changed due to the length change of the telescopic device, and the change of the driving mechanism and the striker plate in two positions is illustrated in the figure. The driving device is used for driving at least the striker plate to be positioned at two positions which can be kept stable, one is the position where the discharge hole is covered, the other one is the position where the striker plate is covered with the end part of the discharge hole to form a certain included angle, and the striker plate is blocked in the discharging direction of the discharge hole, so that the material flow of the discharge hole can be limited. In addition, the striker plate also plays a role in limiting the throwing distance of the material blanking in the horizontal direction, counteracts the throwing force of the material in the discharging direction of the discharging port due to the moving inertia, and guides the material to be thrown in the extending direction of the guide plate. Thereby realizing the adjustment of the throwing angle of the blanking.
Referring to the attached drawings, the telescopic device is selected from an oil cylinder, an air cylinder or an electric cylinder.
