Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetable harvester for heading leafy vegetables on the ground, such as cabbage and Chinese cabbage.

[0002]

2. Description of the Related Art Conventionally, as a vegetable harvester of this type, a pulling / conveying device pulls a lower portion of a vegetable crop from both left and right sides and conveys it upward and rearward to pull out the crop from the field, and then pull out the vegetable crop. , There is one that cuts off the root of the stem and collects only the head part.

[0003]

In the conventional harvesting machine, which carries out finishing cutting during extraction and transportation of headed vegetables such as cabbage, there is a large difference in resistance when extracting vegetables, depending on field conditions and varieties. It is a big point for maintaining the performance of. The present invention aims to eliminate such an unstable element. To achieve this purpose, the following technical measures were taken.

[0004]

That is, the technical means according to the present invention comprises a pair of conveyor belts 6 facing each other.
7 includes a pulling and conveying device 5 for pulling and conveying heading vegetables from the left and right toward the upper rear, and in front of the pulling and conveying device, the roots of the vegetables planted while submersing in the soil of the ridges are provided. A pair of left and right rotary cutters for cutting
It is characterized in that 9, 9 are provided.

[0005]

The root portion of the heading vegetable planted while sunk in the soil of the ridge is cut by a pair of left and right rotary cutters. Then, the heading vegetables are pulled from the left and right by the pulling-out / conveying device and conveyed upward and rearward, and pulled out from the field.

[0006]

As described above, according to the present invention, since the root of the heading vegetable is cut by the cutter in advance, the pulling resistance can be reduced and the pulling can be performed without being influenced by the field condition and the variety condition. Can be facilitated and the performance can be stabilized. Moreover, since the cutter will loosen the soil on the upper part of the ridge when cutting the root part, not only can the above-mentioned pulling resistance of vegetables be further reduced, but it will be combined with the cutting of the root part where much soil is attached to the next stroke part. Never lift the soil.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. The vehicle body 1 is equipped with a crawl-type traveling device 2,
A driver's seat 3 and a control unit 4 are provided on one side of the upper front part.
A pulling / conveying device 5 is provided from a lower front portion to a rear upper portion of the vehicle body 1. The pulling-out / conveying device 5 picks up the headed vegetables from the left and right and pulls out the headed vegetables from the field while conveying them upward and backward, and is provided so as to incline backward and upward along the front-rear direction. The device 5 is composed of two conveyor belts 6 and 7 facing each other. 8 is a container.

A pair of left and right rotary cutters 9 for cutting the roots of vegetables planted while burrowing in the soil of the ridges are provided in front of and below the transport start end of the pull-out transport device 5. 9 is provided. The cutters 9 and 9 rotate inward with respect to each other, and are interlocked with each other via a transmission mechanism in a transmission case 10 projecting forward from the transfer device 5 so as to be capable of high-speed rotation drive.

The configuration shown in FIGS. 3 and 4 will be described.
Below the front of the pulling / conveying device 5, a rooting device 11 for cutting the roots of the vegetables planted while submerging in the soil of the ridge and forcibly breaking the soil is detachably provided. The excavation device 11 is composed of a tapered (conical) spiral body 12, and a transmission case 10 projecting forward from the transfer device 5.
It is configured so that it can be rotationally driven through the internal transmission mechanism. Reference numeral 13 is a grounding wheel.

The configuration shown in FIGS. 5 to 7 will be described. The harvest pretreatment device 14 is arranged on the left side in the traveling direction of the machine body, the driver's seat 3 and the control section 4 are arranged on the right side, and the lifting conveyer bucket conveyor 15 is arranged in the middle portion in the left-right lateral direction. is doing. A platform 16 is provided between the end of the pretreatment device 14 and the start of the bucket conveyor 15 as a communication passage for harvested products. A storage tank 17 is arranged in the upper rear part of the vehicle body.

The pre-harvest treatment device 14 mainly comprises a pair of left and right guide rollers 18, 18 for introducing and guiding the heading vegetables to be planted, a rotary cutting blade 19 for cutting the stem roots of the heading vegetables, It is composed of a pair of left and right belt conveyors 20, 20 that grips and transports the ball head portion. Reference numeral 21 is a roller support rod, and 22 is a guide support, which is fixedly supported by a support frame 23 projecting from the machine side. 24 is a roller supporting rod 2
Links 25 pivotally connect the rear ends of the belt conveyors 1 and 21, and 25 is a link that pivotally connects the front ends of the belt conveyors 20 and 20. These links 24 and 25 are provided with an interlocking rod 26 so that the long hole 2
It is interlockingly connected via 7 freely. The guide rollers 18 and 18 (roller support rods 21 and 21) are pivotally mounted around fulcrums P and P so as to be swingable. Belt conveyor 20, 2
0 is pivotally attached around the fulcrums Q and Q so as to be swingable. The rotary cutting blade 19 is supported by a roller supporting rod 21 and swings integrally with the roller supporting rod 21.

Therefore, even if the head-wound vegetable is cultivated in a meandering manner, the guide roller 18 comes into contact with the head-wound vegetable and oscillates in accordance therewith, and the rotary cutting blade 19 moves in accordance with this and the stem-root portion is moved. Since the cutting is carried out, the bulb portion after cutting can be satisfactorily conveyed, but the operation operation becomes easy. The configuration shown in FIGS. 8 to 15 will be described.

A cabbage holding plate 28 and a grass body 29 are provided on the left and right sides at the start end side of the transporting device 5 that holds the cabbage from the left and right and transports it upward and rearward. Grass body 29
Is a ground sled part 30, a weeding inclination guide part 31, and a bending holding part 3.
2, the ground sled portion 30 separates the outer leaf from the bulb portion, and the sloping guide portion 31 holds the sloping portion while guiding the sward portion toward the holding plate 28 side. The curved holding portion 32 holds the catching portion. Then, an expansion / contraction drive mechanism 35 including a cylinder 33 and a piston 34 is provided in the grass body 29, and a cutting blade 36 is attached to the tip of the piston 34.
The reciprocating movement of the cutting blade 36 causes the cutting blade 36 to move in and out of the hole 37 to cut the stem portion of the cabbage held in the tilted state. The extension / contraction drive mechanism 35 is used for the cabbage holding plate 2.
It is configured to operate in association with the sensing operation of the sensing switch 38 provided on the eight side.

According to the grass body 29 having the above-described shape, the outer leaf of the cabbage can be separated from the head portion, and moreover, the cabbage can be held in a tilted state. The stem of the cabbage can be easily cut.
