Description

Earthwork paver

technical field

The invention relates to a roadbed construction machine, in particular to an earthwork paver.

Background technique

Now the usual operation process of earthwork filling is: "loading, transporting, flattening, compacting", but in actual operation due to various restrictions of natural conditions, it is difficult to carry out coherently according to the plan, and it is impossible according to the current operation method Solving these problems will seriously affect the construction progress and benefits, and there are many companies that have caused losses. The main reasons are: 1. The quality of earthwork filling is based on the degree of compaction, and whether it can be For compaction, the water content of the soil is the key. Different soil types have their optimum water content. For example, the optimum water content of general loess is between 10% and 12%. On this basis, the compaction effect is the best. The reality is that the soil is either dry or wet, and it is rare when it is just right. The traditional construction method is: add water when the soil is dry. Generally, two methods are used: irrigation in the soil borrow pond or watering on the working surface, and these two methods are affected. The problem of water unevenness, if the soil is wet, it must be dried. After spreading the soil, plow and rake repeatedly. If the sun is sunny and the wind is strong, it may take a day or two. If it is cloudy and there is no wind, it may take three or four. Day, if it rains during the drying period, you have to start from the beginning; 2. The earthwork construction in the rainy season is a headache. Not only is there the possibility of being exposed to rain during the drying period, but there is also the problem of resuming work as soon as possible after the rain. The cycle is longer, and it is more likely to suffer from rain again, falling into a vicious circle; 3. "Depending on the weather" is the status quo of earthwork construction. Staff delays, machinery rents, delays in construction schedules, and fines for breach of contract make the construction unit miserable.

Provided by Fig. 1 to Fig. 3, the present invention comprises the box body of left end opening, and the left end of box body 2 rotates and is equipped with longitudinal soil receiving wheel, and the part of receiving soil wheel is placed outside box body 2, and the box below right side of receiving soil wheel The body 2 is rotated with a longitudinal crushing wheel. There are soil retaining plates 3 placed on both sides of the crushing wheel on the lower side of the casing 2. There is an excavation opening at the right end of the casing 2 corresponding to the crushing wheel. The first fan 4 and the first water tank 5 are installed on the end face. The air outlet of the first fan 4 is placed in the box body 2 to the left of the crushing wheel, close to the place directly above the crushing wheel and tilted to the right. There is an outlet pipe on the first water tank 5. 6. The other end of the water outlet pipe 6 is placed in the air outlet of the first fan 4, and the first automatic flow regulating valve 7 is installed on the water outlet pipe 6.

The excavation mouth of said box body 2 rear end is equipped with horizontal soil conveyance passage 8, and the rotation in soil conveyance passage 8 is fixed with the horizontal third rotating shaft 9 that two horizontal intervals are arranged, and the third rotating shaft 9 is provided with a plurality of intervals. The screw conveying blade 10, the soil conveying channel 8 is equipped with a horizontal tube 11 placed above the middle of the two third rotating shafts 9, the lower edge of the horizontal tube 11 has a plurality of through holes arranged at intervals, and the inner cavity of the horizontal tube 11 communicates with a set The second blower fan at the upper end of the soil conveying passage 8, the air outlet of the second blower fan is connected with a conduit, the other end of the conduit is connected with the second water tank placed at the upper end of the soil conveying passage, the conduit is equipped with a second automatic flow regulating valve, so There are vertical soil guide rollers 12 that are respectively placed on the outsides of the two third rotating shafts 9 near the right port in the said soil conveying channel 8 .

Said first fan 4, the second fan, the first automatic flow regulating valve 7 and the second automatic flow regulating valve are connected with a controller, and the crushing wheel, the soil receiving wheel, the third rotating shaft 9 and the soil guide roller 12 are connected with powerplant.

Said first fan 4 and the second fan are hot air fans.

In order to achieve a better effect of receiving soil, said box body 2 is equipped with a bulldozing plate 13 placed on the left side of the soil receiving wheel. The lower end surface of the bulldozing plate 13 is higher than the ground and lower than the longitudinal centerline of the soil receiving wheel. The bulldozing blade 13 can push the rough soil ahead to make things convenient for the soil receiving wheel to receive the soil.

Said soil receiving wheel includes a first rotating shaft 14 fixed in rotation in the box body 2, and the first rotating shaft 14 is provided with multiple sets of receiving soil blades 15 uniformly distributed in the circumference at intervals in the longitudinal direction.

Said pulverizing wheel comprises the second rotating shaft 16 that rotation is fixed in the box body 2, and the second rotating shaft 16 longitudinal intervals is provided with many groups of pulverizing hammers 17 that are uniformly distributed on the circumference, and said pulverizing hammers 17 and the soil-holding blades 15 are connected to each other. Staggered.

The air outlet of the fan is connected with a water tank, and the water tank can cooperate with the fan to form water mist during use.

The present invention can use existing road construction machinery as power car 1, as loader, bulldozer and grader etc., when for example using loader, can unload the hopper of loader as power car 1, the right end of box body 2 It is fixed to the left end of the power car 1, and its soil conveying channel 8 is placed under the belly of the power car 1; during use, the present invention can finish the humidity control work of the earthwork simultaneously in the process of finishing paving, and its flow process is: On the working surface after unloading the soil, the soil is collected by the soil wheel, crushed by the crushing wheel, and the humidity is adjusted by the fan and the water tank. The crushing is to break the large soil clods into tiny particles, which increases the contact area and is conducive to the air-drying of the wet soil. And the rapid evaporation of water after paving is also conducive to the rapid and uniform combination of dry soil and water mist. Humidity adjustment means to adjust the water content of the soil. When the water content is too high, use the mechanical fan to dry it. When the water content is too low, Just use the water tank on the machine to add water and spray water mist, the present invention can also use the soil conveying passage 8 to deliver the soil to the right side of the power car 1, and the soil guide roller 12 in the soil conveying passage 8 can remove the soil in the soil conveying passage 8. Paving to both sides makes the earth paving more uniform, and can make the rolling without wheel marks after paving, and it is easier to distribute water. The invention replaces the bulldozer or loader (rough pushing) and grader ( Scraping), plow and rake machine (tilling), the present invention can also replace the road mixer to complete the mixing operation of lime soil and fly ash soil.

The invention has simple structure, stable performance, high paving efficiency, can quickly adjust the humidity of the earthwork, greatly shortens the drying cycle of the earthwork, and can achieve "preading and pressing now" to a certain extent, reducing the impact of rainy weather on the earthwork. The influence of construction improves the construction efficiency and benefit.
