Embodiments of the present invention

The utility model will be further described below in conjunction with the description of the drawings and specific embodiments.

The inventor found through research that: when unloading in existing warehouses, the discharge port is generally set at the bottom of the silo, so that the receiving box for receiving materials cannot be placed under the silo; and Because the discharge port is set at the bottom, it cannot be cleaned and maintained well, and the performance is not high.

Therefore, in order to solve the above problems, the applicant designed a side discharge device.

Example 1

This embodiment includes: a material warehouse, which is used to store or place materials. The bottom of the material bin is provided with a transition bin communicating with the material bin, and a discharge channel is fixed on one side of the transfer bin, and the discharge channel is connected with the over bin. Here, the transition bin and the discharge channel may be fixedly connected by welding, or a sealed connection may be formed by bolts. Therefore, in the process of unloading, the material is discharged from the bottom of the material bin through the transition bin and the discharge channel in turn. A box or bag that receives the material can be placed at the outlet of the discharge channel.

However, because the material needs to be bent at an angle to reach the exit of the discharge channel, if there is no other external force, it is actually difficult for the material to bend. Therefore, an external force for reversing the flow of materials is provided in the interior of the transition bin.

The above purpose is mainly achieved by the following mechanism: an installation box is fixed below the transition bin, and a transmission mechanism is arranged inside the installation box. At the same time, a cone is rotatably arranged at the center of the chassis of the transition bin, and the cone is in transmission connection with the transmission mechanism, that is, the transmission mechanism is used to control the rotation and steering of the cone.

The transmission mechanism includes a rotating shaft, the top of the rotating shaft passes through the chassis and is fixedly connected to the bottom surface of the cone, and the bottom of the rotating shaft is mounted on the bottom surface of the mounting box through a bearing. Wherein, the connecting part between the rotating shaft and the chassis is a sealed connection, and technologies such as a sealing ring are used to realize the sealing of the chassis to prevent leakage of materials from the connection. The bottom surface of the mounting box plays a strong supporting role for the rotating shaft and the cone fixedly connected with the rotating shaft. In addition, the transmission mechanism further includes: a drive motor fixed on the mounting box, a second gear is fixed on the output shaft of the drive motor, a first gear is fixed on a rotating shaft inside the mounting box, and The first gear meshes with the second gear.

If the material warehouse is too low or the material density is high, you can also fix the mounting box on the bottom surface through the bracket to increase the support strength.

When unloading is required, the drive motor in the transmission mechanism is turned on, and the output shaft of the drive motor drives the second gear to rotate. Driven by the second gear, the first gear rotates on its own, that is, it is coaxial with the first gear. The connected cone rotates. When the cone rotates, the material and air near the cone will flow, and the flow direction is consistent with the rotation direction of the cone, and the material will be thrown into and out of the material channel under the driving of the airflow.

In order to enable the material to be well thrown into the discharge channel, the inner and outer side walls of the discharge channel are inclined relative to the transition bin along the direction of rotation of the cone.

Example 2

In Example 1, the cone is driven to rotate the surrounding airflow to realize the reversal of the material, but the cone is set in the center after all, and the strength of the airflow at the periphery of the chassis is actually very weak. The reversal of the material at the location is not very strong, so in order to enhance the overall airflow effect, the inventor made an improvement: a number of force arms are fixed at the bottom of the cone, and the force arms are along the edge of the cone. Axis array distribution. The force arm is used to increase the area involved in the air flow, and the air flow can be continued to the edge of the transition bin. The force arm is linear.

Example 3

In the second embodiment, the linear force arm can maintain the effectiveness of the airflow, but during the rotation process, due to the certain scheduling between the material and the discharge channel, it is difficult to ensure that the material can be efficiently switched to In the spout channel, therefore, the outer side wall of the spout channel is tangent to the transition bin, the inner side wall of the spout channel is parallel to the outer side wall, and the reverse extension line of the inner side wall is parallel to the The bottom of the cone is tangent. At the same time, the inclination angle α _{1 of} the cone satisfies the following condition: α ₁ = arctg [(R-L)/h ];

In the formula, R is the diameter of the transition silo, L is the distance between the outer side wall and the inner side wall of the discharge channel, and h is the distance from the top surface of the chassis to the top of the transition silo; and the α ₁ satisfies and simultaneously satisfies: 25º≤α ₁ ＜30 º. That is, when α _{1 is} not satisfied: 25º≤α ₁ ＜30 º, if α _{1 is} too small, the material will accumulate on the cone; when α _{1 is} too large, it will not have the effect of reducing pressure.

At the same time, the arc-shaped force arm is set to meet the following conditions: the force arm is an arc-shaped force arm. The arc-shaped force arm bends in the direction of the discharge channel. That is, the force arm also functions as a push rod to push the divided material into the discharge channel in a rotating form.

Because the arc-shaped force arm has the function of pushing materials, in order to prevent the material from being blocked in the discharge channel, in addition to the airflow generated by the cone and the arc-shaped force arm, it also passes through the distance between the force arm and the width of the discharge channel. The relationship between the two to control: the distance M between the edges of adjacent arc-shaped arms meets the following conditions:

.

when

At this time, as shown in Figure 3, the edge of the two adjacent force arms is exactly the same as the distance between the outlet channel and the transition silo, that is, the material between the two force arms is at the moment When the cone continues to rotate, it is pushed into the discharge channel, so it plays a role of fixed-frame pushing.

In order to avoid the frequency of freeze-frame push is too high, so control

. Then through the airflow inside the bin, the material is further pushed outward in the discharge channel.
