Description

Technical Field

[0001] The utility model belongs to the field of concrete tank trucks, and in particular relates to a tank mouth structure of a concrete tank truck. Background Art

[0002] In a concrete tank truck, the tank body is tilted and arranged on the tank truck. The front and rear ends of the tank body are both connected to the vehicle body for rotation. The tank body is provided with a driving mechanism connected to the vehicle body, which can rotate forward and reverse. The rear end of the tank body has a tank mouth, and a sealing tube is provided on the inner side of the tank mouth. The tank body is provided with spiral blades, and the inner side of the blades is connected to the sealing tube, and the outer side of the blades is fixed to the inner wall of the tank body. The rear side of the tank body is provided with a feed hopper and a discharge chute, and the feed hopper and the discharge chute are both connected to the vehicle body. The discharge end of the feed hopper extends into the sealing tube, and the feed end of the discharge chute is located below the tank mouth. Its working principle is that concrete enters the tank body from the feed hopper and the sealing tube. During transportation, the tank body keeps rotating forward, and the blades drive the concrete to move inward, while stirring the concrete to avoid stratification and solidification of the concrete. When discharging the concrete, the tank body is reversed, and the blades drive the concrete to move outward, and the concrete is discharged from the tank mouth and falls to the designated position through the discharge chute.

[0003] Due to the tilted setting of the tank, the concrete cannot fill the entire tank. However, for high-slump concrete, due to its poor fluidity and the fact that the blades continuously push the concrete inward (toward the front of the vehicle) during transportation, the storage height of the concrete in the tank can still be relatively high, and can exceed the lowest point of the tank mouth by a large amount. Therefore, the space utilization rate of the tank body remains high. However, for low-slump concrete, due to its high fluidity, the storage height of the concrete in the tank is relatively low, and cannot exceed the lowest point of the tank mouth, which greatly reduces the space utilization rate of the tank body. Therefore, the current situation is that for high-slump concrete, concrete tank trucks are used for transportation, and for low-slump concrete (below 50mm), such as concrete used for pouring reservoir dam panels (between 30-50mm), trailer-type agricultural vehicles are used for transportation, but during transportation, the concrete is easily stratified and solidified due to vibration, and the effect is not good.

[0021] Embodiment. A concrete tanker mouth structure is improved on the basis of an existing concrete tanker, such as Figure 1 As shown, the concrete tank truck includes a vehicle body 1 (only a part is shown), a tilted tank body 2 is provided on the vehicle body 1, the front and rear ends of the tank body 2 are both rotatably connected to the vehicle body 1, a driving mechanism connected to the vehicle body is provided on the tank body 2, the tank body 2 can rotate forward and reverse, the rear end of the tank body 2 has a tank mouth, the inner side of the tank mouth is provided with a sealing tube 3, the tank body 2 is provided with a spiral blade 17, the inner side of the blade 17 is connected to the sealing tube 3, the outer side of the blade 17 is fixed to the tank body 2, the rear side of the tank body 2 is provided with a feed hopper 18 and a discharge chute 19, the feed hopper 18 and the discharge chute 19 are both connected to the vehicle body 1, the discharge end of the feed hopper 18 extends into the sealing tube 3, and the feed end of the discharge chute 19 is located below the tank mouth. Features are as follows:

[0022] The tank mouth structure of the concrete tank truck includes a baffle assembly 4 covering the tank mouth. The baffle assembly 4 is in a circular shape and includes a left side plate 5 and a right side plate 6. The left side plate 5 and the right side plate 6 are both nylon plates. A hinge shaft 7 connecting the vehicle body 1 is provided between the left side plate 5 and the right side plate 6. The hinge shaft 7 is located at the top of the baffle assembly 4. A locking mechanism 8 is provided between the left side plate 5 and the right side plate 6. The locking mechanism 8 is located at the bottom of the baffle assembly 4. The locking mechanism 8 is a buckle, a part of the buckle is fixed to the left side plate 5, and the other part of the buckle is fixed to the right side plate 6.

[0023] The arc surface inside the left side plate 5 and the arc surface inside the right side plate 6 are both provided with a sealing strip 9 elastically connected to the sealing tube 3, and the sealing strip 9 is a rubber strip. The arc surface inside the left side plate 5 and the arc surface inside the right side plate 6 are both provided with a card slot 10, and the sealing strip 9 is provided with a card strip 11 matched with the card slot 10.

[0024] The left side plate 5 and the right side plate 6 are both provided with a handle 12. The handle 12 provides a force application point when the baffle assembly 4 is opened, and the operation is labor-saving.

[0025] The left side plate 5 is provided with a positioning pin 13 which is inserted into the right side plate 6. The positioning pin 13 is used to keep the left side plate 5 and the right side plate 6 on the same plane when they are closed, so that the sealing effect will be better.

[0026] A pin shaft 14 fixed to the vehicle body 1 is disposed above the hinge shaft 7 , and a rotating plate 15 is disposed on both the left side plate 5 and the right side plate 6 , and a hook 16 is disposed at the end of the rotating plate 15 .

[0027] Both sides of the lower part of the baffle assembly 4 are provided with limiting plates 20 fixed to the vehicle body 1, and the limiting plates 20 are used to keep the baffle assembly 4 in contact with the tank mouth but not pressed tightly.

[0028] Working principle: When transporting low slump concrete, Figure 2 As shown in FIG. 1 , the baffle assembly 4 formed by the left side plate 5 and the right side plate 6 closes the space between the feed hopper 18 and the tank body 2, that is, closes the tank mouth. When concrete enters the tank body 2 from the feed hopper 18, the height of the concrete can be relatively large. When the concrete needs to be discharged from the tank body 2, as shown in FIG. Figure 3 As shown, the locking mechanism 8 is opened, the left side plate 5 and the right side plate 6 are rotated upward through the corresponding handles 12, and the hook 16 is hung on the pin 14 to open the can mouth.

[0029] Due to the friction between the tank body 2 and the left and right side plates during transportation, the left and right side plates will wear. To reduce wear, the baffle assembly 4 is only used to close the tank mouth when transporting low slump concrete. The baffle assembly 4 is in a closed position at other times. Figure 3 The open state.
