DETAILED DESCRIPTION

[0019] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0020] refer to Figures 1 to 3

[0021] A single-sensor metering mechanism comprises a metering cylinder 1, on both sides of the upper part of which are arranged box racks 9 for connecting to a frame, a weighing sensor 5 for connecting to the frame is fixed on the back of the metering cylinder, and a discharge door 8 driven by a driving mechanism for opening and closing the lower port of the metering cylinder is installed on the metering cylinder.

[0022] In this embodiment, the packing frame is a corner plate and waist-shaped holes 91 are provided on both side plates, and reinforcing plates 16 connected to the packing frame are fixed on both sides of the upper part of the metering cylinder. The reinforcing plates are connected to the waist-shaped holes of the packing frame without being locked, so as to fix the position of the metering cylinder; the packing frame is fixedly connected to the frame.

[0023] In this embodiment, a mounting weldment 3 is fixed on the back of the metering barrel, the weighing sensor is mounted on the mounting weldment, and the rear end of the weighing sensor is connected to the frame via a mounting plate 4. By mounting the weighing sensor on the back of the metering barrel, no angular difference phenomenon will occur under ideal conditions.

[0024] In this embodiment, the driving mechanism includes a vertically arranged cylinder 2 with a telescopic rod facing downwards, the upper end of the cylinder is hinged to the back of the metering cylinder, one end of the discharge door is hinged to the metering cylinder via a shaft 73, a rotating handle 72 is fixed to the discharge door, and the end of the rotating handle away from the discharge door is hinged to the telescopic rod of the cylinder. Thus, the discharge door is driven by the cylinder to open and close the lower end of the metering cylinder.

[0025] In this embodiment, a reinforcing rib 15 is fixed to the upper back of the metering cylinder, a single ear seat 22 is fixed on the reinforcing rib, and the single ear seat is hinged to a connecting seat 21 fixed to the upper end of the cylinder.

[0026] In this embodiment, a pair of crank swivels 6 are fixed to the lower back of the metering cylinder via a crank adjustment block 14, a connecting tube 71 is fixed to one end of the discharge door, the shaft rod passes through the connecting tube and is fixedly connected to the connecting tube, and the two ends of the shaft rod are respectively rotatably connected to the crank swivels via bearings 74, so as to facilitate the rotation of the discharge door.

[0027] In this embodiment, a fisheye joint 23 is fixed to the lower end of the telescopic rod of the cylinder and is hinged to the rotating handle via a pin shaft 24, thereby driving the rotating handle to drive the discharge door to rotate around the shaft.

[0028] In this embodiment, the metering cylinder is composed of a rectangular cylinder and a rectangular conical cylinder 11 connected to the lower part of the rectangular cylinder. A sealing strip groove 13 is provided around the lower port of the rectangular conical cylinder and a sealing strip is installed, so that it can fit tightly when the discharge door is closed.

[0029] In this embodiment, a through-plate mounting seat 8 is fixed to the upper back of the rectangular cylinder of the metering cylinder, and a weight hanging seat plate 12 is fixed to the rectangular conical cylinder of the metering cylinder and the mounting weldment.

[0030] Working principle: the material continues to fall into the metering cylinder 1 until it reaches the target value set by the weighing sensor 5, the cylinder 2 retracts, the handle 72 rotates upward with the cylinder, drives the discharge door 7 to open, and the material falls into the metering cylinder. When the weighing sensor 5 detects that the material is empty, the cylinder 2 extends, the handle 72 rotates downward with the cylinder 2, the discharge door 7 closes, and the material falls into the metering cylinder..., that is, Figure 3 shown.

[0031] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0032] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0033] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated forming process.
