Description

Technical Field

[0001] The utility model relates to the technical field of feeding, in particular to a feeding hopper for a slurry sealant truck. Background Art

[0002] A slurry sealant truck is a special mechanical equipment for road maintenance and construction, mainly used for the slurry sealant treatment of road surfaces. Slurry sealant is a pavement preventive maintenance technology. By mixing materials such as cement, emulsified asphalt, water, aggregate (such as fine sand), additives, etc. in a certain proportion into a slurry state, and then evenly spreading and compacting on the road surface to form a thin and dense protective layer. The slurry sealant truck integrates functions such as material storage, mixing, transportation, spreading, and compaction. For example, a synchronous super-viscous fiber micro-surfacing slurry sealant truck with the publication number CN 206034251 U transports the above materials and glass fibers to the mixing system for mixing. The materials contain both cement and emulsified asphalt with relatively high viscosities, granular aggregates, liquid or powder additives, and substances in various states such as water. The transportation of granular materials can be carried out through a conveyor belt, and the liquid or semi-liquid materials can be transported through pipelines. Pipeline transportation requires a pump to provide the transportation power. If the material enters the inside of the feeding hopper from the feeding port opened on the side wall of the feeding hopper, the semi-liquid material may splash inside the feeding hopper due to too much pump power, resulting in waste.

[0003] It can be seen that the existing technology still needs to be improved. Summary of the Utility Model

Detailed implementation manners

[0018] The present utility model provides a hopper for a slurry sealant truck. To make the purpose, technical solution and effects of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0019] Please refer to Figure 1 and Figure 2 , the present utility model provides a hopper for a slurry sealant truck, including a hopper body 1, the upper part of the hopper body 1 is open; a through hole 11 is opened at the bottom of one side wall of the hopper body 1, a first feed pipe 2 is arranged in the through hole 11, the end of the first feed pipe 2 extending into the hopper body 1 is a closed end, the extending direction of the first feed pipe 2 is parallel to the length direction of the hopper body 1, and a plurality of discharge ports 21 extending along its length direction are opened on the first feed pipe 2, and the plurality of discharge ports 21 are all arranged towards the outlet of the hopper body 1.

[0020] In practical applications, the upper part of the hopper body 1 is the end of the conveyor belt 10. For example, granular materials such as aggregates are conveyed by the conveyor belt 10 until they reach the end of the conveyor belt 10 and then fall into the hopper body 1. Therefore, the upper part of the hopper body 1 is designed with an open top to adapt to the feeding of materials. The outlet of the hopper body 1 is located above the mixing mechanism. Therefore, various materials put into the hopper body 1 will enter the mixing mechanism from the outlet of the hopper for sufficient mixing. For example, semi-liquid materials or materials with a certain viscosity such as cement and emulsified asphalt are conveyed through the first feed pipe 2 and fed through the plurality of arranged discharge ports 21. The above structure limits the position of the first feed pipe 2, so that the first feed pipe 2 is located at the bottom of the hopper body 1. Even if material splashes occur, due to the set position of the first feed pipe 2, the material can fall back into the hopper body 1; by limiting the extending direction of the first feed pipe 2 and the orientation of the plurality of discharge ports 21, the material entering the first feed pipe 2 can flow out from the plurality of discharge ports 21 facing the outlet of the hopper body 1, which is beneficial to alleviating the problem that only one discharge port 21 is provided in the prior art, resulting in excessive pressure at this position and easy material spraying.

[0021] In some embodiments, the bottom of the hopper body 1 is inclined, and the inclined direction of the hopper body 1 faces the outlet of the hopper body 1; the first feed pipe 2 is arranged away from the outlet of the hopper body 1. The hopper body 1 with the bottom inclined towards the outlet of the hopper body 1 provides a guiding inclined plane for the material, and under the action of the self-gravity of the material and the guiding of the inclined plane, the material can accurately fall into the stirring mechanism. The first feed pipe 2 is arranged away from the outlet of the hopper body 1, which can also prevent the horizontally extending first feed pipe 2 from blocking other materials.

[0022] In certain embodiments, a second feed pipe 3 is arranged at the bottom of the hopper body 1; the second feed pipe 3 is located between the first feed pipe 2 and the outlet of the hopper body 1. The arrangement of the second feed pipe 3 can provide a conveying pipeline for the feeding of other materials. Specifically, for example, materials with strong fluidity and low viscosity such as water are conveyed through the second feed pipe 3 to avoid splashing of materials with poor fluidity at the end of the second feed pipe 3. Moreover, the materials with good fluidity can wash the materials with poor fluidity so that as much material as possible can enter the stirring mechanism.

[0023] In some embodiments, first guiding inclined plates 41 are respectively arranged on the left and right side walls of the hopper body 1, and a vertically arranged limiting plate 42 is fixedly connected to the upper surface of the first guiding inclined plate 41. As described above, the upper part of the hopper body 1 is the end of the conveyor belt 10, so the arranged first guiding inclined plates 41 can be used to guide the materials conveyed by the conveyor belt 10 to smoothly enter the hopper body 1. The arrangement of the limiting plate 42 is used to block the materials conveyed by the conveyor belt 10 to prevent the materials from falling outside the hopper body 1 and causing waste.

[0024] In some embodiments, second guiding inclined plates 5 are respectively arranged on the left and right inner side walls of the hopper body 1, and the distance between the two second guiding inclined plates 5 gradually decreases. The various materials entering the hopper body 1 accurately fall into the stirring mechanism located below the hopper body 1 under the guiding action of the second guiding inclined plates 5 to avoid the materials spilling outside the stirring mechanism.

[0025] In some embodiments, a handle 6 is arranged on the side wall of the hopper body 1, and the handle 6 is arranged on the side wall away from the outlet of the hopper body 1. Specifically, the side wall at the outlet end of the hopper body 1 is detachably connected to the vehicle body (for example, by plugging), so the hopper body 1 can be removed as a whole by using the handle 6 for easy cleaning and maintenance.

[0026] In some embodiments, mounting plates 7 extending downward are respectively provided on the left and right side walls of the hopper body 1. A plurality of first jacks 71 are formed in the mounting plates 7, and the distances from the plurality of first jacks 71 to the ground are not equal. A pin 8 is inserted into any one of the first jacks 71, and the end of the pin 8 is also used to be inserted into a second jack (not shown in the figure) provided on the vehicle body. By inserting the pin 8 into different first jacks 71, the inclination angle of the hopper body 1 is changed, that is, the angle at which the material is put into the mixing mechanism is adjusted.

[0027] In summary, in the present utility model, a first feed pipe 2 extending horizontally is provided at the bottom of the hopper body 1, and a plurality of feed ports facing the outlet of the hopper body 1 are formed in the first feed pipe 2, so that the material entering the first feed pipe 2 can flow out from a plurality of discharge ports 21, alleviating the problem that only one discharge port 21 is provided in the prior art, resulting in excessive pressure at this position and solving the problem that the material is likely to spray out.
