Description

A bulb crop for harvest root-harvester}

The present invention is mounted on the rear of the tractor relates to the excavator for harvesting bulbous crops, such as sweet potatoes, potatoes, onions, in detail, the width can be adjusted according to the width of the pit planted bulbous crops, plows according to the number of pike It is configured to limit the number.

Generally, bulbous crops refer to such plants as sweet potatoes, potatoes, onions, and the like, and the bulbous crops have a lot of time and effort and have to be hand-picked by hand.

In order to solve this problem, registered patent 10-0353476 (design name: tractor-attached sweet potato extraction device), published patent 10-2007-0025409 (design name: sweet potato harvester), registered design 20-0448815 (design) Name: cultivator detachable sweet potato harvesting device) was provided.

Among these prior arts, Patent No. 10-0353476 (design of the tractor: sweet potato excavation device attached to the tractor) adjusts the depth of excavation according to the slope of the land in which the sweet potatoes of bulbous crops are grown, thereby preventing the damage of sweet potatoes that may occur during the excavation. It is possible to prevent, and also published Patent Publication No. 10-2007-0025409 (design name: sweet potato harvester), which is caused by the influx of sweet potato stems because it prevents the inflow of sweet potato stems into the excavator in advance despite the mechanical harvest As it is possible to minimize transportation defects and damage to the surface of sweet potatoes, it is possible to obtain high prices in the market by increasing the commercialization of the sweet potato. Not only is it mechanically sound, but the sweet potato stem is I can just clean up the furrows that eliminates interference or hindrance in the work due to the sweet potato stem, so have a beneficial effect such as to improve the collection and gulchwi workability.

The operation state of the harvesting excavator for bulbous crops according to the present invention configured as described above will be described schematically.

1 to 5 of the plow bracket 36 constituting the plow device 30 by operating the plow turning means 60 of the bulb harvester crop harvester excavator detachably connected to the tractor rear end 11 as shown in the tractor Matching the plow blades 35 with sweet potatoes, potatoes, onions, and the like planted, and then driving a tractor tilling the pike by the plow blades 35 to excavate the bulbous crops.

In this way, the tiller planted with bulbous crops (potatoes, potatoes, onions) is tilled to excavate the bulbous crops (potatoes, potatoes, onions, etc.). 30) is moved by the left and right moving device 40 (see Figs. 6 and 7).

That is, as shown in FIGS. 8A and 8B, the fastening force of the bolt 55 and the nut 56 of the blocking member 50 constituting the left and right moving device 40 is released in sequence.

In this state, if the moving bracket 32 constituting the plow device 30 is moved in and out, the square moving holes 42 and 43 in the lower portion of the moving bracket 32 move in and out along the horizontal frames 19 and 20. To the side. At the same time, the plow bracket 36 is provided with a blocking member 50, a rear pivoting lever 34, and a plow blade 35 to which the fastening force of the bolt 55 and the nut 56 is loosely connected to the reinforcing fixing piece 45. And the plow turning means 60 is moved.

Then, when the bolts 55 and nuts 56 which are loosely fastened completely are completely fastened, the upper portion of the horizontal piece 52 of the blocking member 50 comes into close contact with the lower portions of the horizontal frames 19 and 20 to move the bracket 32. ) Is firmly fastened and fixed to the horizontal frames 19, 20, the width of the plow device 30 is adjusted appropriately to the width of the patina.

In this state, the plow bracket 36 of the plow device 30 is operated as the plow turning means 60 to match the plow blade 35 with the plowed planted bulbous crop, and then the tractor plow blade 35 when the tractor is operated. The pike is tilled and the bulbous crops (potatoes, potatoes, onions) are excavated.

At this time, the bulb plow crop damage prevention unit 37 is detachably mounted on the plow blade 35 at the inner side of the plow bracket 36 curved plow, so that the plow blade 35 is damaged when the soil is excavated during tillage of the soil. Is prevented. That is, the bulbous crops excavated by the plow blade 35 are moved along the curved inner surface of the curved block pieces 37a constituting the bulbous crop damage preventing unit 37, and the bulbous crops (potatoes, potatoes, onions) Damage to the outer surface is prevented and the quality is excellent.

On the other hand, as shown in Figure 9a, Figure 9b to select one or two of the plurality of pike to excavation work one of the plurality of plow brackets 36 (4 in the drawing) constituting the plow device 30 Or by selecting two to operate the plow rotation means 60 to rotate the hydraulic cylinder 64 upward to separate from the bank.

When this is schematically described, when the driver selectively operates one or two of the operation switch 86 provided in the tractor 1, as shown in FIG. 10, the corresponding control valve 84 is blocked so that the corresponding hydraulic cylinder As the hydraulic pressure of 64 passes through the hydraulic line 72 and flows out to the tractor hydraulic device 74 through the connecting hose 81 of the lower block 82, the piston rod 66 inside the hydraulic cylinder 64 The plow bracket 36 and the plow blade 35 fastened and fixed to the rear pivot lever 34 are moved upward as the rear pivot lever 34 pivots in the direction of the arrow about the pivot pin 33. Rotated away from the head (see Fig. 9b).

When the tractor is operated in this state, the plow is tilled by the remaining plow blades 35, and the bulbous crop is excavated.

On the other hand, as shown in FIG. 10, when the driver selectively operates one or both of the operation switches 86 provided in the tractor 1, the control valve 84 corresponding thereto is opened so that the corresponding tractor hydraulic device 74 is opened. When the hydraulic pressure of) flows into the hydraulic cylinder 64 through the connection hose 81 of the lower block 82 and the hydraulic line 72 of the corresponding hydraulic cylinder 64, the piston inside the hydraulic cylinder 64 The rod 66 moves backward so that the plow bracket 36 rotates downward to be in close contact with the ridge.

In the above description of the harvester for harvesting bulbous crops, but not limited thereto, the present invention is also available for harvesting root herbs such as bellflower, deodeok, wild horse, ginseng.
