Description

Technical Field

[0001] This utility model relates to a loading device mainly used in the field of dispensing bulk powders such as grains, food, and chemicals. Specifically, this utility model discloses a special loading device for powder tank trucks. Background Technology

[0002] With the rapid development of my country's logistics industry, the use of bulk tank trucks for long-distance transportation of powdery materials such as flour, starch, and cement has become increasingly common. Currently, the market mainly uses the method of aligning the loading pipe of the tank truck with the feed inlet for loading. However, due to the limitations of the tank truck's shape, the falling bulk material eventually forms a cone-shaped pile, which inevitably affects the tank truck's ability to be completely filled and cannot reach its rated loading capacity. Although there are multiple loading ports on the top of the tank truck, it is still impossible to guarantee that the tank truck will be completely filled. This problem is particularly prominent for powders with poor flowability. Multiple feed inlets shorten the distance between adjacent feed inlets and can increase the loading capacity to some extent. However, the increase in the number of feed inlets not only increases the number of times on-site operators need to move the truck position and increases loading time, but there are still situations where the area around each inlet is not fully filled. For large-volume transportation, this increases the number of tank truck trips and the operation time. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a special loading device for powder tank trucks that can increase the loading capacity of tank trucks and make the loading capacity controllable.

[0004] According to the technical solution provided by this utility model, the special high-efficiency loading device for powder tank trucks includes a loading shell, a geared motor housing, a geared motor, blades, a geared motor housing mounting pipe, a sensor, a protective net, a connecting flange, and a geared motor mounting flange.

The inner diameter of the cylindrical upper section is larger than that of the cylindrical lower section. The inner diameter of the upper end of the conical upper section is smaller than that of the lower end. The inner diameter of the upper end of the conical lower section is larger than that of the lower end.

There is a material discharge gap between the geared motor housing 2 and the loading housing 1. A geared motor mounting flange 9 is fixed inside the lower end of the geared motor housing 2. A geared motor 3 is fixed on the upper surface of the geared motor mounting flange 9. The output shaft of the geared motor 3 extends downward. A blade 4 is fixed at the lower end of the output shaft of the geared motor 3. The upper half of the blade 4 is located inside the cylindrical lower section 1.4 of the loading housing, and the lower half of the blade 4 is located below the cylindrical lower section 1.4 of the loading housing.

[0023] A protective net 7 is fixed on the outer circle of the lower section 1.4 of the loading shell cylinder, and the protective net 7 covers the lower half of the blade 4;

[0029] The working principle of this utility model is as follows:

[0030] This utility model is installed on the discharge end of the loading pipe. The connecting flange 8 in this utility model is used to connect the loading pipe. When feeding, the blade 4 rotates clockwise under the drive of the reduction motor 3. The bulk material diffuses more widely under the thrust of the blade 4 and the action of airflow, which can increase the cone angle of the material pile. This can effectively solve the problems of low loading efficiency and small loading capacity of tank trucks. When the bulk material gradually accumulates to the upper section 1.2 of the loading shell cone, one of the sensors 6 senses the bulk material and the feedback signal starts timing. At this time, the blade 4 continues to rotate clockwise, and the bulk material continues to feed under the thrust of the blade 4, thereby squeezing the bulk material in the upper section 1.2 of the loading shell cone and spreading it to the surroundings. When the set time is reached, the loading pipe stops feeding. When the bulk material in the loading pipe is gradually emptied, one of the sensors 6 senses that there is no material and the feedback signal starts timing. The bulk material in the loading pipe is completely pushed into the tank truck under the action of the blade 4, the reduction motor 3 stops, and the loading pipe retracts.

[0031] By adjusting the relevant time parameters of the PLC controller in this invention, the loading capacity of the tanker truck can be controlled automatically.

[0032] In this utility model, one of the geared motor housing mounting tubes 5 is used to connect the power line of the geared motor 3, and the other geared motor housing mounting tubes 5 are used to dissipate heat from the geared motor 3.

[0033] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
