Description

Technical Field

[0001] The invention relates to a 360-degree rotary cutting, breaking and bridging weighing system. Background Art

The stirring structure is arranged in the storage chamber and is connected to the drive motor through a drive shaft and a gear set. This structure has a long transmission distance and high energy consumption, which will cause a large motor load and a short motor life. In addition, the stirring structure generally adopts fan-type stirring or a combination of multiple L-shaped stirring rollers for stirring. This structure has low stirring efficiency, many dead corners, and poor bridging effect. Summary of the Invention

[0003] In order to solve the above problems, the present invention proposes a 360-degree rotary cutting, bridging and weighing system, which aims to solve the problems of high energy consumption and heavy motor load caused by the external driving motor of the bridging of the existing dust weighing device.

[0009] A feeding device, wherein the feeding device is arranged on the frame, and the feeding end of the feeding device is connected to the discharging end of the stirring chamber;

[0010] and weighing devices.

[0011] This technology sets an annular driving motor between the feeding chamber and the stirring chamber. The material falls into the stirring chamber after passing through the annular driving motor from the feeding chamber, and is stirred and bridged by the stirring blades of the stirring chamber. Since the annular rotor of the driving motor is located at the opening of the stirring chamber, the stirring blades are directly connected to the annular rotor to realize transmission. The annular rotor moves circumferentially along the chute. Since the connection area between the annular rotor and the chute is large, the rotation is smooth, which reduces the loss of the motor and extends the life of the motor.

[0012] In one or more embodiments, an air inlet is provided on the outer shell, a first air cavity is provided above the stator, and a second air cavity is provided below the stator. The first air cavity and the second air cavity are connected, and the air inlet is connected to one or both of the first air cavity or the second air cavity.

In the present technical solution, a first air cavity and a second air cavity for ventilation are provided on the inner cavity, and the first air cavity is connected to the first air outlet end, and the second air cavity is connected to the second air outlet end. During ventilation, heat can be taken away, so that the motor can be cooled quickly, and the motor's service life is improved. At the same time, the purity of the first air outlet end and the second air outlet end makes it difficult for dust to enter the inner cavity from the gap, thereby ensuring the cleanliness of the inner cavity and improving the life of the motor.

[0015] In one or more embodiments, a second limiting ring and a third limiting ring are arranged below the second air cavity, a gap is provided between the second limiting ring and the third limiting ring to form a slide groove, and a rotor limiting top block is provided on the slide groove at circumferentially uniform intervals, and the rotor limiting top block moves in the direction toward the center line of the casing to adjust the position of the annular rotor.

The gas in the second air cavity passes through the gap and is ejected from the air outlet of the gap to cool down and prevent dust from entering the inner cavity. During operation, the gap is filled with gas, which can cause friction between the upper part of the annular rotor and the air when it rotates, greatly reducing resistance, increasing the rotation speed, and reducing rotational heat.

[0017] In one or more embodiments, the stirring blade includes a first blade body and a second blade body, the first blade body is formed with an open arc shape to cooperate with the stirring chamber, the opening is upward, the second blade body is mounted on the opening to support the first blade body, the first blade body and the second blade body rotate along the center line of the second blade body, the first blade body destroys the bottom foundation of the bridge, and the second blade body destroys the cross-section of the bridge.

[0018] In one or more embodiments, the first blade includes an integrally formed center portion, a first arc arm, and a second arc arm. The center portion is located between the first arc arm and the second arc arm. The side of the center portion facing the second blade is a top surface, and the side of the center portion facing away from the second blade forms a bottom surface. The top surface forms a narrow surface to reduce the load, and the bottom surface forms a wide surface or a narrow surface.

[0019] In one or more embodiments, the width of the first arc arm is greater than the width of the central portion, and the second arc arm is symmetrically arranged with the first arc arm.

[0020] In one or more embodiments, connecting portions are provided at left and right ends of the second blade, and the connecting portions are connected to the annular rotor.

[0021] In one or more embodiments, the feeding device is provided with at least one screw and a feeding motor, and the feeding motor drives the screw to rotate, and the rotating screw conveys the material to the weighing device.

[0022] Beneficial effects of the present invention: This technology arranges an annular driving motor between the feeding chamber and the stirring chamber. The material falls into the stirring chamber after passing through the annular driving motor from the feeding chamber, and is stirred and bridged by the stirring blades of the stirring chamber. Since the annular rotor of the driving motor is located at the opening of the stirring chamber, the stirring blades are directly connected to the annular rotor to realize transmission. The annular rotor moves circumferentially along the chute. Since the connection area between the annular rotor and the chute is large, the rotation is smooth, which reduces the loss of the motor and extends the life of the motor.
