Description

  The present invention relates to a headed vegetable harvesting apparatus that cuts and separates a headed portion of a headed vegetable and an outer leaf in order to harvest the headed vegetable such as cabbage vegetated on a cocoon.

  As a harvesting machine for harvesting headed vegetables such as cabbage, for example, the one described in Patent Document 1 is known. The harvesting machine described in Patent Document 1 is used to extract a headed vegetable such as cabbage vegetated on a cocoon by a drawing device such as a pre-drawing processing device provided in the front part of the machine body, and in the middle of transporting this to the rear of the machine body, It is configured to cut leaves.

  Usually, the cabbage vegetated on the straw in the field has few stems extending straight upward, and the stem is bent due to the weight of the head part and often falls to the left and right of the straw. When the cabbage is tilted in this way, cutting the inclined cabbage cuts the head part and damages it, thereby impairing the commercial value.

For this reason, in the headed vegetable harvesting apparatus described in the cited document 1, the cabbage is scraped by a pre-drawing processing apparatus having a pair of left and right discs. The size of the device is small because the size of the device becomes large, and it is difficult to take a configuration in which the drawing devices are arranged side by side due to restrictions on the width of the ridge, making it difficult to make multiple harvesting machines. Is desired.

After adjusting the height position of the rotary blade 43a and receives Ri conveyor 30 Thus, to advance the heading toppers device 1. As the head vegetable harvesting apparatus 1 advances, the outer leaves are weeded by the left and right guide rods 52 and 72a, and the tilted head portion is raised and guided to the front of the rotary blade 43a.

  When the headed vegetable harvesting apparatus 1 further moves forward, as shown in FIGS. 9 to 11, the divider rods 46a and 46b protruding forward from the rotary blade 43a are inserted into the bottom left and right of the headed part, and the headed part is cut off from the stock. It is drawn in a standing posture in front of the department.

  When the vehicle body 10 further advances, the head portion held in the standing posture by the divider rods 46a and 46b is cut and separated from the outer leaf by the stock cutting unit. At this time, the head part being separated from the root and the root and outer leaf remaining on the heel are pushed by the rotary blade 43a, but the head part is rotated by the divider rod 46a on the lower side in the rotational direction of the rotary blade 43a. The roots and outer leaves are pressed by the lower side of the rotary blade 43a by the stock holding rod 47.

The head portion cut and separated from the outer leaves passes through the head vegetable path P. That, is pushed by the lug 81 of the infeed device 8 which rotates in the direction of the arrow in FIG. 6 is fed to the rear, it is placed in the receiving Ri conveyor 30 up sliding slope 45 provided on the rear of the stock based on the cutting unit. At this time, the guide rods 55,75a left and right which extends to receive Ri conveyor 30 is prevented falling into the field of head-forming portion. Cut heading unit is conveyed by the receiving Ri conveyor 30 and conveyor 31 to the rear, are loaded into the integrated vehicle 33 to follow from behind the vehicle body 10.

  The embodiment of the figure configured as described above has the following advantages.

  The left and right divider rods projecting forward from the stock cutting part of the rotary blade draw the headed vegetables to the front of the stock cutting part and hold the head standing upright while The outer leaf can be cut and separated, and it is possible to reliably cut and separate from the outer leaf without damaging the head portion with a simple configuration.

In addition, when the head is cut and separated from the outer leaf by the rotary blade, the vegetable vegetables are pressed on both the upper and lower sides of the rotary blade by the divider rod and stock holding rod located on the lower side in the rotation direction. The headed vegetables can be cut reliably without being pushed by the rotary blade, and a beautiful cut surface can be obtained. Since the stock holding press rod is bent and provided on the upper side in the rotational direction than the divider rod to which the stock is attached, it can reliably hold the stock of the small-sized headed vegetables.
Furthermore, with the divider rod alone, the cut stem (or stockholder) may be drawn into the rotary blade and stuck between the divider rod and the rotary blade, stopping the rotary blade. By providing the former presser rod, the cutting blade is not drawn and the rotating blade can be smoothly rotated.

  In addition, since the head portion can be reliably cut and separated by such a simple configuration, it can be arranged side by side to greatly improve the efficiency of the work by the multi-row processing. In addition, since the configuration is simple, problems and the like are not likely to occur, the device can be used for a long time, can be formed at a low cost, and requires less labor for maintenance and the like.

  Such significant efficiency improvement by the multi-row processing is advantageous not only for normal harvesting of headed vegetables but also particularly for so-called wintering cabbage. So-called wintering cabbage needs to be cut and separated just before the snow falls, but if the cabbage is cut too early, it will freeze and discolor before the snow falls, and the taste and flavor will be significantly impaired. This is because the cabbage is buried in the snow and the cutting work cannot be performed after the snow has accumulated.

  In such a wintering cabbage, the cut cabbage is accumulated in the field. In this case, as shown in FIG. 4 where the illustration of the conveyor is omitted, the headed vegetable harvesting device does not need to be provided with a transport device, and the cut cabbage is not transported to the stacking car but is directly released to the field. When configured in the two-row hunting as in the present embodiment, the cabbage falls into the ridges sandwiched between the left and right ridges straddled by the vehicle body, and the labor and labor of the subsequent accumulation work can be suppressed.

  Moreover, the headed vegetable harvesting apparatus shown in the figure further includes a conveyor for transporting the cut head part to the rear of the vehicle body, and a rotating blade is disposed immediately before the conveyor, and the head part that has been cut and separated is fed to the conveyor. A feeding device is provided, and the headed portion is reliably inherited by the conveyor. Therefore, while cutting the necessary head part while leaving the unnecessary outer leaf part on the basket, it can be transported and collected by the conveyor without dropping the head part on the field, and in normal cutting work Post-processing work such as dirt removal is not required, and work efficiency can be improved.

  In addition, it can be cut from the roots without pulling out the vegetative vegetables that are vegetated on the cocoons, so there is no risk of scattering the koji soil, and it is necessary to leave the unnecessary outer leaves on the cocoons without contaminating the heads. The head portion can be cut. When dredged soil is scattered and adheres to the rotating blade, the contaminated rotating blade will contaminate the cut surface of the head part, requiring labor for cleaning work, and the product value will be significantly reduced without removing the dirt. Therefore, it is important in cutting work to prevent the dredged material from scattering.

  The cutting device includes an output shaft provided in the left-right direction of the vehicle body, a front-rear shaft extending forward from the output shaft, a vertical axis extending downward from the front-rear shaft, and a rotation provided at the lower end of the vertical axis. It is composed of a blade, and a shaft fulcrum is formed on the output shaft so that the front and rear shafts can be rotated around the shaft fulcrum, and the height position of the rotary blade can be adjusted by rotating the front and rear shafts It becomes. Therefore, it is possible to cut and separate the head portion at a position close to the top surface of the heel by reducing the height of the rotary blade, and to cut the head portion with many outer leaves attached to the head portion. It is possible to cut at a position floating from directly above the heel and cut the head with few outer leaves, and improve workability by cutting at a desired position according to the work. Can do.

  For example, in wintering cabbage etc., the cut cabbage is discharged to the field, so soil will adhere to the head, but the height of the rotary blade can be adjusted so that the rotary blade is close to the top surface of the fence. In addition, it is possible to suppress the contamination of the head part by cutting the head part so that many outer leaves are attached.

In addition, it has a feeding device with a lug attached to the peripheral surface of the endless feeding belt placed above the slope and conveyor, and the heading part is pressed against the lug and pushed backward, so the heading part is secure To the rear of the aircraft. Further, since the infeed device is provided above the rotary blade and the receiving Ri conveyor is compactness without lateral width increases the cutting work portion is held, never hinder multi-start of.

  Also, the rear part of the feeding device is elastically supported by a suspension mechanism, and depending on the size of the cut and separated head part, the rear part is lowered and the lug pushes the head part when small, and the rear part is pushed by the head part when large. Pushed up.

  In addition, the lug is formed by forming a contact surface side of the head portion with a buffer member and attaching a backing plate having elasticity to the head portion, and the head portion is pushed rearward by the elastic backing plate. Since the buffer member abuts on the portion, there is no risk of damage.

Further, the upper surface of the body center side of the rotary blade, receives Ri and slope is provided with a length and a slope that reaches the front end upper surface of the conveyor, since the step between the rotary blade and the receiving Ri conveyor is eliminated The head part pushed by the lug slides up the slope, and the head part can be easily and reliably sent to the conveyor by the feeding device.

  The headed vegetable harvesting device shown in the figure has a guide device made up of a guide rod, a cutting device made up of a rotary blade, and a feeding device on the left and right respectively on a vehicle body straddling two ridges, and cuts the two pieces simultaneously. Although it is the structure which works, according to the cutting work part of the simple structure mentioned above, it is also possible to take the structure of 3 or more multi-hunting. It is also possible to take a single-hunting configuration. Further, a cutting machine having a simple configuration in which an engine is mounted on a walking type vehicle body instead of the riding type as shown in the present embodiment can be provided.
