Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a technique for mechanizing the work of harvesting root vegetables such as carrots and radish.

[0002]

[Prior Art]

 Conventionally, the work of harvesting root vegetables has been performed manually by pulling out the root vegetables buried in the field one by one and then cutting off the leaves with a kitchen knife.

[0003]

[Problems to be solved by the device]

 Since the manual harvesting of root vegetables is a laborious task of pulling the root vegetables out of the field with a bent posture, realization of a mechanized root vegetable harvester was desired. It is an urgent issue in large-scale fields. The present invention is intended to realize and provide a root vegetable harvesting machine in which the work of extracting root vegetables from the ground is mechanized.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a pair of left and right endless swivel belts that are driven to face each other in a rearwardly inclined state so that the root portion of a root vegetable is pinched and the root vegetable is pulled upward from the ground. In addition to providing a pulling-out section for pulling up, the root vegetable is equipped with a pulling-up device in front of this pulling-out section that exerts a pulling action on the root vegetable leaf portion before pulling-out to forcibly raise the posture of the root vegetable leaf portion. It is characterized by constituting a kind harvester.

[0005]

[Action]

 The above-mentioned characteristic configuration focuses on the fact that the roots of root vegetables project above the ground, and the function of the extraction unit that clamps the leaves and gives a pulling force mechanically extracts the root vegetables in the ground. It is based on the idea of However, it is rare for many leaves of root vegetables to stand straight up in the sky, and most of them are scattered around and fallen down. It is difficult to exert the leaf pinching action. In view of this, in the present invention, since the pulling device is provided in front of the pulling-out portion, the pulling-up device is provided in front of the pulling-out portion to exert a pulling action on the root vegetable leaf portion before pulling out to forcibly raise the posture of the root vegetable leaf part. By standing upright toward the extraction part, it becomes possible to reliably exert the pinching action of the leaf part at the extraction part, and it is not possible to pinch the leaf part, or the leaf part is lifted by pinching only a few leaf parts. There is no case that the pulling out work does not work due to breakage of the.

[0006]

[Effect of the device]

 Therefore, by using a structural device equipped with a pull-out section that utilizes the existence of the leaf section and a pull-up device that grasps the posture of the leaf section, mechanization of the pulling operation can be achieved in a state where pulling mistakes are unlikely to occur, and the harvesting can be achieved. We were able to reduce labor while contributing to improved efficiency.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Fig. 5 shows a root vegetable harvester according to the present invention, and Fig. 5 is a plan view of the front part thereof. 0 is a pulling device, 1 is a pulling unit, 2 is a conveying device, 3 is a leaf cutting device, and 4 is a harvesting device. A part 5, a crawler traveling device, and a control part 6 are provided. The pulling device 0 includes a pair of locking and transporting mechanisms 21 each of which is formed by winding a belt 19 having a large number of locking claws 18 around upper and lower wheels 20 and 20 having axes inclined in the left-right direction and the vertical direction. The pair of left and right locking and transporting mechanisms 21 and 21 are arranged so that the distance between them becomes narrower toward the upper side. In addition, 7 is a weeding tool. The pulling-out section 1 is equipped with a conveyor type sandwiching conveyor device 9 extending immediately after the locking and conveying mechanism 21 and the site of the leaf cutting device 3. The sandwiching conveyor device 9 is composed of a pair of left and right conveyor belts 11 and 11 which are driven while facing each other in a rearwardly inclined posture. The transport device 2 is composed of the above-mentioned sandwiching conveyor device 9 and a pair of left and right guide mechanisms 12 and 12 arranged below the transport belt 11, and the lower part of the root and vegetable leaf part is provided between the pair of guide mechanisms 12 and 12. By guiding and guiding the upper part of the leaf part by driving a pair of conveyor belts 11 and 11, it has a function of conveying the root vegetables sent from the pulling part backward. As shown in FIGS. 2 and 3, the guide mechanism 12 is composed of a roller belt 15 provided with a roller 14 that is rotatable around the horizontal axis Y for each chain link 13. The roller 14 is attached to the chain link 13 in a state in which a spring 16 can generate an outward biasing force, so that the leaves of the root vegetables are sandwiched between the left and right rollers 14 and 14 facing each other. The rearward transfer force of the conveyor belt 11 is received, and the transfer speed thereof is almost the same as the speed of the conveyor belt 11. Further, the vertical distance between the conveyor belt 11 and the guide mechanism 12 is set to be wider than the sandwiching conveyor device 9 so that the rearward inclination angle of the guide mechanism 12 becomes wider toward the lower side in the conveying direction. . As shown in FIG. 4, the left and right conveyor belts 11 and 11 are provided with a large number of rolling wheels 17 for pressing the conveyor belts 11 and 11 in the directions in which they are present to generate a leaf-holding force. In the front portion 11a of the conveyor belt up to the portion corresponding to the front end of the guide mechanism 12, the strength of the spring 8 of the rolling wheel 17 is set so that a strong clamping force acts to pull out the root vegetables in the ground, and Then, in the rear portion of the rear conveyor belt 11b, the gripping force of the leaf portion is set to be weak by using a spring 10 which is thinner than the spring 8 in the front portion 11a of the conveyor belt. At the rear position of the guide mechanism 12, a leaf cutting device 3 that cuts off the leaves of the root vegetables with a rotary cutter 14 is arranged.

The main operation of the harvesting work will be described. As shown in FIG. 1, the pulling device 0 raises the leaf portions that lie down and disperse and aligns them in an upright posture, and the leaves in the upright and aligned state. The root part in the ground is pulled out by sandwiching the part with a strong gripping force by the front part 11a of the conveyor belt and lifting it upward and rearward, and then the root vegetables by the rear part 11b of the conveyor belt and the guide mechanism 12. However, since the guide mechanism 12 has a gentle inclination, the upper surface of the root vegetable main body gradually approaches the roller 14, and the roller 14 is contacted with the upper surface of the root vegetable main body at the rear of the guide mechanism 12 in a contact conveyance state. become. After that, since the rearward conveying force is transmitted to the root vegetables due to the weak clamping force of the rear portion 11b of the conveyor belt, the leaves are allowed to slip through downward. The upper surface thereof is brought into contact with the roller 14 to be in a transporting state, and a constant posture and position with respect to the leaf cutting device 3 to be withheld next is maintained. By the way, the pulling device 0 may be configured by arranging a plurality of gear-shaped rotating bodies in a V-shape in a front view like the locking and conveying mechanism 21 of the above embodiment.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
