In the process, part of the waste materials can be scattered on the road surface which is not milled, the scattered waste materials can cause certain blocking effect on the material milling machine, meanwhile, the milling square amount of the milling machine during milling operation can be changed, and then the waste materials on the conveying belt are more, the conveying pressure is high, and the service life of a conveying part (such as the conveying belt) on the conveying mechanism can be shortened for a long time.

According to an embodiment of the present invention, it is intended to improve at least one of technical problems existing in the prior art or the related art.

To this end, according to an embodiment of the present invention, it is an object to provide a material conveying control method for a milling machine.

Another object of an embodiment of the present invention is to provide a material conveying control system for a milling machine.

According to an embodiment of the present invention, it is a further object to provide a milling machine.

In order to achieve the above object, according to an embodiment of the first aspect of the present invention, there is provided a material conveying control method for a milling machine, including: step S110: acquiring the lifting displacement of a material receiving machine of the milling machine in a floating state; step S200: and controlling the rising height of the material receiving machine and the advancing speed of the milling machine according to the lifting displacement so as to control the material conveying amount of the milling machine.

According to an embodiment of the first aspect of the invention, the lifting displacement of the receiving machine of the milling machine in a floating state is obtained to determine whether the receiving machine meets an obstacle. It will be understood that during operation of the milling machine, some waste material will be spilled on the un-milled road surface and form obstacles, thus forming obstacles to the machine, which when entering the milling work area will result in a change of the milling square of the milling drum, affecting the outward transport of the waste material. The material receiving machine is controlled to ascend according to the ascending and descending displacement quantity, and meanwhile, the advancing speed of the milling machine is controlled, so that the advancing speed of the milling machine is adaptive to the height of the material receiving machine, the milling square quantity of the milling machine is controlled, and the material conveying quantity of the milling machine is adjusted. The floating state refers to a state that the lifting mechanism of the material receiving machine has no driving force and only ascends or descends under the action of external force.

According to the feeding control method of the milling machine, the ascending height of the material receiving machine and the advancing speed of the milling machine are controlled simultaneously, so that the variable quantity of the milling square amount is reduced, the process that the milling machine conveys waste materials to the waste material transport vehicle is kept relatively stable, meanwhile, the waste material amount generated by milling operation of the milling machine in unit time is relatively stable, the condition that the milling square amount of the milling machine in unit time exceeds the load of a conveying part (such as a material conveying belt) is avoided to a certain extent, the abrasion of the conveying part is delayed, and the service life of the conveying part is prolonged.

It can be understood that the receiving machine and the feeding device of the milling machine are both provided with conveying parts, and the conveying parts can be conveying belts or other parts capable of conveying waste materials. Waste materials generated by the milling drum enter the material receiving machine and then sequentially pass through the material receiving machine and the conveying part of the material conveying device to be conveyed into a hopper of the waste material transport vehicle, so that the increase of the quantity of the waste materials generated by milling operation of the milling drum can increase the load of the conveying part, and the service life of the conveying part is influenced.

In the technical scheme, in the specific step of step S200, the size of the obstacle is determined by judging whether the lifting displacement of the receiving machine is greater than a first displacement threshold. If the lifting displacement of the material receiving machine is larger than the first displacement threshold value, the size of the obstacle is larger, the blocking effect on the material receiving machine is larger, and the milling square amount of the milling machine can be greatly influenced, at the moment, the material receiving machine is controlled to ascend by a first height proportion and is kept stable, so that the material receiving machine avoids the obstacle, and the resistance is reduced; furthermore, the travelling speed of the milling machine is controlled according to the first height proportion, the first speed proportion is correspondingly reduced, the travelling speed change of the milling machine is matched with the rising height of the material receiving machine, the variable quantity of the material conveying quantity of the milling machine is reduced when waste materials are scattered on a non-milled road surface, the relatively stable conveying quantity of the conveying mechanism is ensured, and the service life of a conveying part (such as a material conveying belt) is prolonged. Wherein, the first height proportion refers to the ratio between the lifting height of the material receiving machine and the maximum allowable lifting height.

In the technical scheme, after the material receiving machine rises for a first height proportion and is kept stable, after a first time interval, the material receiving machine is determined to cross an obstacle, the material receiving machine is controlled to be restored to a floating state, the material receiving machine naturally descends for a second height proportion under the action of gravity, the material receiving machine is restored to a state of contacting a road surface, correspondingly, the advancing speed of the milling machine is controlled to accelerate the second speed proportion, the advancing speed of the milling machine is matched with the height of the material receiving machine, and therefore the variation of the milling square quantity of the milling drum is reduced. Wherein the first time interval may be set according to a travel speed of the milling machine.

In the above technical solution, the first height ratio is in a direct proportional relationship with the first speed ratio; the second height ratio is in direct proportion to the second speed ratio.

In the technical scheme, the first height proportion and the first speed proportion are defined to be in a direct proportional relationship, and the second height proportion and the second speed proportion are defined to be in a direct proportional relationship, so that the travel speed variation of the milling machine corresponds to the lifting height variation of the material receiving machine, and the variation of the milling square amount of the milling drum is reduced. Furthermore, when the direct scaling factor is properly selected, the milling square amount of the milling drum can be kept constant.
