Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a degraver that removes gravel mixed in soil such as farmland.
[0002]
[Prior art]
In farmland that contains gravel in the ground and freezes in the winter, or farmland with severe sediment runoff, it is necessary to remove the surface gravel every few years. Various devices for removing gravel have been proposed. For example, in Japanese Utility Model Publication No. 61-62966, a debris transporting device is attached to the front of a self-propelled vehicle, a gravel sorting device made of a rotating wire mesh is attached to the vehicle body, and debris is removed from the center of the vehicle body. A structure is proposed in which the gravel is transported by a conveyor that is dropped down and protrudes to the side of the vehicle body. The debris transporting device has an excavation claw at the tip, a flower conveyor at the middle, and a lot conveyor at the rear. Further, a conveyor is provided on the upper surface of the debris transporting device so that earth and sand and gravel can be transported smoothly.
[0003]
[Problems to be solved by the invention]
In the conventional debris remover, the debris transporting force is used to scoop up the tip claw of the debris transport device into the soil, and the debris work is performed while pulling up the sand on the debris transport device. However, in the case of soil that contains a lot of gravel or hard soil, the transport resistance due to friction between the side plate of the debris transport device and the earth and sand increases, which reduces the running speed and smoothes the transport of earth and sand. There is a problem that the debris efficiency is lowered.
[0004]
In addition, in the case of soil having a relatively high viscosity, there is a problem in that earth and sand accumulate at the front part of the debris transporting device, and therefore, the excavation resistance increases and the debris efficiency decreases.
[0005]
In view of the above-described problems, an object of the present invention is to provide a debris machine capable of performing debris work efficiently and at high speed.
[0006]
[Means for Solving the Problems]
The deburring machine according to claim 1 is provided with a debris transporting device having an excavation part at a tip at a front part of a self-propelled vehicle.
The debris transport device comprises a plurality of pins around the periphery and a plurality of debris rods arranged in the front-rear direction to rotate in a direction in which the upper surface side is directed backward,
The debris rod is characterized in that at least the front part of the debris transport device has a pin array that acts in a direction to bring earth and sand or gravel to the center side.
[0007]
In this way, by arranging the pin arrangement of at least the front part of the debris transporting device so that earth and sand and gravel are brought closer to the center side, the earth and sand and gravel move toward the center side, The frictional resistance with the gravel is reduced, the running speed is not lowered, the amount of debris per time or the output of the machine is improved, and the debris efficiency is increased.
[0008]
The degraver according to claim 2 is the same as claim 1,

It is characterized by having.
[0009]
In this way, once the earth and sand and gravel that have been brought closer to the center are once again dispersed to the outside, debris is removed using the entire surface of the debris rod, and the debris efficiency of the entire debris transport device It can contribute to improvement. Also, at the front part of the debris transporting device, the sediment is actively dropped onto the ground, and thereafter the amount of earth and sand on the debris transporting device is reduced, so that the transport of the sand and gravel spreads. Even if it goes, the resistance by friction with the side plate does not increase so much, and the efficiency does not decrease.
[0010]
The degraver according to claim 3 is the same as claim 2 ,
Wherein a rear portion of the vibration gravel transport device, and the rear portion of the dividing gravel rod assembly having a pinout that acts in a direction to gather outside the removal gravel transport device sediment or gravel, direction lapping the sand or gravel in the center side A debris rod assembly having a pin arrangement acting on
A debris transporting device is provided at the rear of the debris transporting device .
[0011]
In this way, by providing a pin arrangement that moves toward the center of the debris transport device as a debris rod at the rear of the debris transport device, the gravel is dropped when the gravel falls from the debris transport device to the rear conveyor. It is discharged without spilling.
[0012]
The deburring machine according to claim 4 is provided with a debris transporting device having an excavation part at a front end of a self-propelled vehicle.
A scraping rotary blade that is rotated by a driving device so as to stir the excavated earth and sand is provided above the tip of the debris transporting device so that the vertical position can be adjusted.
[0013]
Thus, by providing a rotary blade for scraping on the top of the tip (excavation part) of the debris transporting device, the earth and sand are unraveled, thereby preventing the front part of the debris transporting device from being clogged with earth and sand, The earth and sand can be smoothly fed to the rear, and the debris efficiency can be improved without slowing down the traveling speed of the debris machine. Further, since the vertical position of the scraping rotary blade can be adjusted, the earth and sand can be loosened at a suitable position according to the excavation depth.
[0014]
The degraver according to claim 5 is the same as claim 4,
Adjacent to the rear portion of the rotary scraping blade, a rotary blade or a chain-type feed blade that scoops up the earth and sand backward is provided so that the vertical position can be adjusted.
[0015]
In this way, by providing a chain-type feed blade following the scraping rotary blade, it is possible to more smoothly send earth and sand and gravel to the gravel sorting section of the debris transport device, and further improve the debris efficiency. it can. Moreover, since the vertical position of the chain type feed blade can be adjusted, earth and sand or gravel can be fed at a suitable position according to the excavation depth.
[0016]
