Description

Technical Field

[0001] The utility model belongs to the field of powder conveying, and more specifically, relates to a powder mixing and conveying vehicle. Background Art

[0002] In the field of powder transportation, usually two powder transportation methods are adopted. One is through a fixed pipeline structure and is achieved by pneumatic conveying and other means. However, this method is relatively inflexible and is generally only suitable for fixed-point and directional conveying, such as internal conveying in a factory. The other is to load the powder into a container and then convey it through a conveying vehicle. Although this is relatively flexible, the powder accumulates in the container and is prone to sticking together to form caking, resulting in difficulty for the final powder to be unloaded smoothly through the pipeline.

[0003] For example, the patent document with the Chinese patent application number: CN201310038475.5 and the publication date: May 1, 2013 discloses a negative-pressure conveying powder combustion system, including a powder bin. The lower part of the powder bin is connected to a conveyor. The conveyor is provided with a discharge port, and the discharge port is connected to a primary conveying pipeline. The rear end of the primary conveying pipeline is provided with a primary distributor. The rear end of the primary distributor is connected to at least 2 secondary conveying pipelines. The rear end of the secondary conveying pipeline is provided with a secondary distributor. The rear end of the secondary distributor is connected to at least 2 powder guns. The discharge end of the powder gun extends into the kiln. A high-pressure centrifugal fan is provided in the middle of the primary conveying pipeline. This solution is the first powder conveying method.

[0004] Another example is the patent document with the Chinese patent application number: CN201720239503.3 and the publication date: February 6, 2018, which discloses a powder fire truck, including a chassis; a slewing mechanism arranged on the chassis; a boom arranged on the slewing mechanism; and a driving air source, a powder supply device, a powder conveying pipeline, and a spraying device arranged at the end of the powder conveying pipeline connected in sequence. The boom includes at least three boom sections with the head and the end hinged in sequence. When the boom shows a tendency to unfold, at least two boom sections rotate in opposite directions around their head hinge points. This solution is the second powder conveying method.

[0005] However, in the above two solutions, neither can solve the previously mentioned problems, that is, how to ensure flexible powder conveying while preventing the powder from sticking and forming caking in the container, resulting in difficulty for the powder to be unloaded smoothly through the pipeline.

Therefore, the scope of the present utility model is only defined by the appended claims.

[0034] Embodiment 1

[0035] A powder stirring and transporting vehicle is used for the transportation and discharging of powder and can realize the flexible transportation of powder. The following describes its specific structure and technical effects in detail.

[0036] As Figure 1 shown, the transport vehicle includes a vehicle body 1, on which a powder container 2, a transfer pump 3 and a powder discharging device 4 are installed. The internal space of the powder container 2 is connected to the inlet of the transfer pump 3 through a feed pipe, and the outlet of the transfer pump 3 is connected to the powder discharging device 4 through a discharge pipe.

[0037] Among them, a stirring device 5 is provided in the powder container 2. As Figures 1 to 3 shown, the stirring device 5 includes an electric control box 51, a main shaft 52, a first stirring member 53, a second stirring member 54, a third stirring member 55 and a fourth stirring member 56. The electric control box 51 is arranged below the powder container 2, and a motor is provided therein. The main shaft 52 is vertically arranged in the powder container 2 and penetrates into the electric control box 51 to be in transmission connection with the output shaft of the motor.

[0038] Specifically, the first stirring member 53, the second stirring member 54, the third stirring member 55 and the fourth stirring member 56 are mounted on the main shaft 52 around the main shaft 52. A flat shovel is installed at the outer bottom of the first stirring member 53 close to the powder container 2, a conical shovel is installed at the outer bottom of the second stirring member 54 close to the powder container 2, and a square shovel is installed at the inner side of the third stirring member 55 close to the powder container 2. The fourth stirring member 56 is installed on one side of the main shaft 52, and a vertical auxiliary shaft 57 is installed at the outer side of the fourth stirring member 56 close to the powder container 2. A plurality of stirring blades 58 are installed at intervals along the circumference of the auxiliary shaft 57, and the auxiliary shaft 57 is rotatably installed vertically on the main shaft 52.

[0039] By providing three stirring members respectively having a flat shovel at the outer bottom, a conical shovel at the outer side and a square shovel at the inner side, when the main shaft 52 rotates, the flat shovel at the outer bottom can break up the caked powder at the bottom of the container, the conical shovel can break up the caked powder at the outer side of the container, and the square shovel can break up the caked powder at the inner side of the container. The three stirring members cooperate to effectively prevent the powder at different positions in the powder container 2 from caking, ensuring that the powder can be unloaded smoothly after the transport vehicle reaches the unloading position.

[0040] On the basis of the three stirring members, the further provided fourth stirring member 56 with the auxiliary shaft 57 enables the auxiliary shaft 57 to rotate simultaneously with the rotation of the main shaft 52 to drive the plurality of stirring blades 58 thereon to rotate. This stirring method can effectively improve the cracking effect on the caked powder in a large range in the powder container 2 and prevent the powder from caking.

[0041] In this embodiment, the flat shovel is in an inclined state, and its height gradually decreases along the rotation direction of the main shaft 52. This arrangement further enhances the cracking effect of the flat shovel on the caked powder at the bottom.

[0042] As Figure 1 shown, the powder unloading device 4 adopts a manipulator, and the discharge pipe is fixed on the manipulator along the length direction of the manipulator. In order to cooperate with the activities of the manipulator, the discharge pipe adopts a flexible pipe to increase the mobility of the discharge pipe and avoid the fracture of the discharge pipe. At the same time, the manipulator is fixedly installed on the turntable 6, and the turntable 6 is installed on the surface of the vehicle body 1 through a slewing mechanism. The slewing mechanism can adopt a common motor in the market to drive the turntable 6 to rotate or a worm and worm gear structure. Its specific structure and technical principle belong to the prior art known to those skilled in the art, so it will not be described in detail here. By driving the discharge pipe by the manipulator for unloading, the unloading of the discharge pipe is made more flexible, and installing the manipulator on the rotatable turntable 6 further enhances this effect.

[0043] In addition, in this embodiment, a switchable maintenance door 11 is provided on the side of the vehicle body 1, which facilitates the maintenance staff to perform maintenance on the internal devices of the vehicle body 1. A regulating valve and a flowmeter are installed on the feeding pipeline, enabling the staff to more precisely control the discharging operation, improving the discharging efficiency and effect.

[0044] In summary, for the powder mixing and conveying vehicle of this embodiment, by improving the structure of the conveying vehicle, it can realize the flexible conveying of powder while preventing the powder from caking in the container, ensuring the smooth discharging of the powder.
