Description

Technical Field

[0001] The invention relates to a side-discharging milling waste output device and a milling vehicle, belonging to the technical field of milling equipment. Background Art

[0002] Currently, milling equipment has two methods for handling waste generated during the milling process: one is to utilize the conveyor belt's transmission characteristics to transport the waste forward or backward to a material receiving and transporting vehicle, and the other is to perform milling only, leaving the milled waste on the original road surface. Small milling machines are often used for municipal construction and shallow milling, requiring not only easy transportation and maneuverability, but also the shallow milling depth and the resulting low waste, making the need for a conveyor belt low. Therefore, most small milling machines currently produced and sold by domestic machine manufacturers are designed without a conveyor belt.

[0003] Under the construction mode of no material discharge, when the milling machine is milling for the second time, the right rear tire of the whole machine has been running on the milled road surface. At this time, the waste remaining on the road surface appears as an irregular shape with multiple edges and sharp angles. Compared with the other tires of the whole machine running on normal roads, the service life of the right rear tire is much shorter than that of tires in other parts due to the continuous grinding damage between it and the milling waste. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a side-discharging milling waste output device and a milling vehicle. By changing the traditional discharge direction, the maneuverability and flexibility of the small milling machine are guaranteed, and the problem of grinding and damage to the right rear tire caused by milling waste is solved.

[0005] To achieve the above-mentioned purpose, the present invention is implemented by adopting the following technical solutions: a milling waste output device with side discharge, comprising a discharge mechanism and a milling chamber, wherein the discharge mechanism is arranged on the side of the milling chamber, a milling wheel is provided in the milling chamber, a plurality of tool seats and ejection plates are circumferentially arranged on the milling wheel, a tool head is provided on the tool seat, the tool head can mill the road surface, and collect the waste generated by milling to the ejection plate, and the ejection plate can throw the waste into the discharge mechanism to realize side discharge.

[0006] Optionally, the discharging mechanism includes a hopper, a discharging port and a tail plate, one side of the hopper is connected to the discharging port, and the adjacent side thereof is connected to the tail plate, and the tail plate is connected to the side of the milling chamber.

[0007] Optionally, panels are provided on both sides of the surface of the tail plate in contact with the milling chamber, and baffle 1 and baffle 2 are provided on the side of the milling chamber corresponding to the panels. The panels are embedded in a slide groove formed by baffle 1 and baffle 2, and can slide up and down in the slide groove.

[0008] Optionally, the tail plate is provided with a support ear for connecting to the oil cylinder, and the telescopic shaft of the oil cylinder can drive the discharging mechanism to slide up and down.

[0009] Optionally, a hard alloy is provided under the tailgate, and the hard alloy can contact the road surface so that the milling waste is accumulated along the forward direction.

[0010] Optionally, the width of the cemented carbide is not greater than the width of the cutter head distribution on the milling wheel.

[0011] Optionally, the tool holders are arranged in a spiral line, and a plurality of spiral lines are evenly distributed on the milling wheel, and the ejector plate is arranged at the starting position of each spiral line.

[0012] Optionally, the number of the spiral lines is 6, and their starting positions are all located on the center line of the milling wheel.

[0013] Optionally, a slide plate 1 and a slide plate 2 are respectively provided on both sides of the outside of the milling chamber, and the slide plate 1 and the slide plate 2 can slide up and down on the side wall of the milling chamber.

[0014] The present invention further provides a milling vehicle comprising the side-discharging milling waste output device described in any one of the above items.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention abandons the traditional milling and discharging method, adopts side discharging, avoids the use of a conveyor belt, significantly reduces the size of the milling device, ensures the maneuverability and flexibility of the small milling machine, and facilitates the rapid repair of the road surface without affecting traffic during road maintenance.

[0017] Compared with the non-discharging method, the non-discharging method easily causes waste to accumulate, rubbing against the cutter block and the right rear tire, reducing their lifespan. In addition, the waste after milling falls directly onto the milled road surface, which is not conducive to the quality inspection of the milled road surface. The side discharging method can overcome the above shortcomings.

[0018] The waste material of the present invention is discharged from the side, and will not cause accumulation inside the milling chamber, thereby avoiding the wear and damage of the cutter head and cutter seat on the milling wheel by the waste material; the waste material of the milled road surface is scraped off by the hard alloy assembled on the bottom of the tail plate, and there is no waste material on the road surface after milling. When the second milling cut is made, the right rear tire will no longer be ground and damaged by the waste material, which can greatly improve the service life of the right rear tire. In addition, since there is no waste material on the milled road surface, the milling effect can be observed and tested without the need for mechanical equipment or manpower to clean it.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0027] Example 1:

[0028] like Figure 1As shown, the embodiment of the present invention includes: a discharge mechanism and a milling chamber 6. The discharge mechanism is provided on the side of the milling chamber 6. A milling wheel 7 is installed in the milling chamber 6 by bolts. The milling wheel 7 is circumferentially provided with a plurality of cutter seats 8 and a throwing plate 12. The cutter seats 8 are arranged in a plurality of spiral lines. The spiral lines are evenly distributed on the milling wheel 7. There are 6 of them. Each spiral line starts from the position of the center line of the milling wheel 7 and ends at the edge of the milling wheel 7. The throwing plate 12 is provided at the starting position of each spiral line. A cutter head 9 is provided on the cutter seat 8. The cutter head 9 and the cutter seat 8 are installed in a detachable manner, which is convenient for replacing the cutter head 9 after it is damaged. The cutter head 9 can mill the road surface and can collect the waste generated by milling to the throwing plate 12 through the arrangement of the spiral lines. Then the throwing plate 12 can throw the waste into the discharge mechanism to achieve lateral discharge.

[0029] Example 2:

[0030] On the basis of Example 1, the discharging mechanism of this embodiment includes a hopper 1, a discharge port 2 and a tail plate 4. The hopper 1 is arranged in a high and low manner, wherein the lower side is connected to the discharge port 2, and the adjacent side connected to the discharge port 2 is connected to the tail plate 4. Panels are provided on both sides of the opposite surfaces where the tail plate 4 is connected to the hopper 1, and baffle 1 13 and baffle 2 14 are provided on the side of the milling chamber 6 corresponding to the panel. Baffle 1 13 and baffle 2 14 are arranged to form a slide groove, and the panel is embedded in the slide groove to play a limiting role to ensure that the discharging mechanism does not fall off.

[0031] There are support ears 3 on both sides below the tail plate 4, which can be connected to the output shaft of the oil cylinder. The oil cylinder is placed on the milling car. When the oil cylinder is started, the discharge mechanism can be driven to slide up and down on the side of the milling chamber 6. When the discharge mechanism slides to the highest point, it is convenient to repair and maintain the tool holder 8 and the tool head 9 on the milling wheel 7.

[0032] Example 3:

[0033] On the basis of Example 2, this embodiment further includes a cemented carbide 5, which is arranged below the tail plate 4. The width of the cemented carbide 5 is no greater than the width of the distribution of the cutter blocks 8 on the milling wheel 7. When the discharge mechanism moves to a suitable position, the cemented carbide 5 can come into contact with the road surface, scraping off the waste on the road surface, causing the milling waste to accumulate along the forward direction of the milling vehicle. After accumulating to a certain extent, it will be collected by the spirally arranged cutter blocks 8 near the ejection plate, thrown into the discharge mechanism through the ejection plate 12, and finally discharged from the discharge port 2, ensuring that there is no milling waste on the road surface after milling, making it convenient for staff to inspect the milling quality and effect.

[0034] Slide plate 10 and slide plate 2 11 are respectively provided on both sides of the outside of the milling chamber 6. Both slide plate 10 and slide plate 2 11 can be controlled by a cylinder to slide up and down on the side wall of the milling chamber 6, making it convenient to maintain the milling device.

[0035] Example 4:

[0036] This embodiment provides a milling vehicle, comprising the side-discharging milling waste output device described in any of the above embodiments.

[0037] The working principle of the present invention is as follows: during operation, the milling wheel 7 is started and rotated at high speed to mill the road surface, generating waste. The waste is concentrated from both sides to the middle along the spiral line formed by the cutter seat 8 on the milling wheel 7, and then thrown into the hopper 1 of the discharging mechanism by the ejection plate 12. The waste is output from the discharge port 2 to the side area of ​​the device by utilizing the inclination angle of the hopper 1. In this way, the waste will not cover the milled road surface, which is convenient for the staff to conduct the quality inspection of the milling effect, and also prevents the right rear tire from crushing the waste during the second milling cut, causing grinding damage, thereby improving the service life of the tire.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
