Description

  The present invention relates to a vegetable harvester that harvests bulb vegetables such as garlic, onion, lily root, and root vegetables such as carrot.

  Conventionally, as a vegetable harvester that harvests vegetables such as garlic, onion, and lily roots (bulb crops), for example, shoots grown in the field from the bulbs in the soil to the ground It is known that it is pulled and conveyed while sandwiching, and cut and harvests the stem and leaf part and the root part extending from the bottom of the bulb part during the conveyance. This kind of vegetable harvesting machine cuts the stem and leaf part and root part of the bulb vegetable from the conveying device that conveys the bulb vegetable extracted from the ground in a state where it is suspended while holding the stem and leaf part. And a cutting device for separating from the bulb part.

Is provided. 2. Description of the Related Art Conventionally, there is a soil dropping device having a structure including a rotating body (star wheel) including a plurality of blades protruding from a rotating shaft portion (see, for example, Patent Document 1 and Patent Document 2).

  Moreover, in a field where bulbous vegetables are cultivated, the multi-film is coated on the straw for the purpose of moisturizing and keeping soil, suppressing weeds, and the like. Such multi-film has been conventionally collected by a collecting device.

  For example, Patent Document 3 discloses a root vegetable harvester equipped with a collecting means for collecting multifilm after sandwiching and transporting the roots and leaves of root vegetables cultivated in a multifilm-coated cocoon. This root vegetable harvesting machine has a configuration in which a multi-film is cut and then lifted from a field scene while the machine is advanced, and the multi-film is wound around a reel and collected. As another example, a multi-film can be collected in advance when harvesting bulbous vegetables by stripping and winding the multi-film on the cocoon while the tractor is running with a winding device attached to the tractor.

That is, the shaft portion 150 is provided at a position away from the side surface of the soil dropping blade 130.

  In the present embodiment, the earth dropping rotating unit 61 rotated by the rotating shaft 63 whose axial direction is the left-right direction of the machine body is provided to rotate in the forward direction, like the multi-dropping rotating unit 101 (see FIG. 6, see arrow X2). In other words, the earth removal rotating unit 61 is provided to rotate counterclockwise (left rotation direction) in the left side view of the machine body. Therefore, the earth removal rotating part 61 moves the blade part 132 located on the upper side from the rear side to the front side by the rotation of the shaft, and the root part 2c of the garlic 2 conveyed by the conveying device 12 toward the rear upper side. The blade 132 is hit against the root 2c so as to face each other.

  As described above, in the present embodiment, the earth removing rotating unit 61 sets the rotation axis direction to a direction (machine body left-right direction) orthogonal to the transport direction by the transport device 12 in plan view of the machine body. The direction of rotation of the earth removal rotating unit 61 is a direction in which the earth removal blade 130 acts on the root 2c of the garlic 2 being conveyed by the conveying device 12 in a direction opposite to the conveying direction by the conveying device 12. is there. In other words, the rotation direction of the soil drop rotation unit 61 is the forward rotation direction as described above (see arrow X2 in FIG. 6).

  The second earth removing device 17 will be described. The second earth dropping device 17 has a pair of left and right earth dropping rotation units 72 whose rotation axis is the direction along the conveying direction of the conveying device 12, and the earth dropping rotation unit 72 is an earth of the first earth dropping device 16. The dropping rotation unit 61 has a substantially common configuration except for the direction of the rotation axis.

  As shown in FIG. 15, the outer diameter, the inter-axis distance, and the phase of the pair of left and right earth-moving rotating parts 72 are such that the blade part 132 of the earth-moving blade 130 of one earth-moving rotating part 72 (72A) is the other earth-moving part. It is set so as to enter within the rotation range (within the rotation trajectory) of the blade portion 132 of the rotating portion 72 (72B), that is, into the recess 133. Further, the rotation directions of the pair of left and right earth-moving rotating parts 72 are opposite to each other so that the root part 2c of the garlic 2 located between them is hit from the upper side to the lower side. That is, as shown in FIG. 15, when viewed from the front side of the machine body (upper conveyance side), the rotation direction of the soil dropping rotation unit 72 </ b> A located on the left side is clockwise (right rotation direction) (see arrow H <b> 1), and on the right side The rotation direction of the earth-moving rotation unit 72B located is counterclockwise (left rotation direction) (see arrow H2). With such a configuration, the root portion 2c of the garlic 2 is alternately hit by the blade portions 132 of the soil removal blades 130 of the left and right soil removal rotation portions 72 and reliably receives the action of soil removal.

  The effect by the vegetable harvesting machine 1 which concerns on this embodiment provided with the above structures is demonstrated.

  According to the vegetable harvesting machine 1 according to the present embodiment, since the multi-dropping device 100 is provided on the front side of the first soil dropping device 16, the soil dropping device (16, 17) or the rooting device 18 is being conveyed. A device acting on the root portion 2c of the garlic 2 can be prevented from being wrapped with foreign substances such as a multi-film, and a decrease in performance of each device can be prevented.

  For example, a multifilm that has collapsed due to deterioration with time or a multifilm that is thin and insufficient in strength is difficult to peel off before the garlic 2 is harvested, and the garlic 2 produced by the vegetable harvester 1 remains on the straw. Harvesting takes place. In such a case, the multi-film is pulled up together with the garlic 2 dug from the straw by the conveying device 12 or the like, and the torn multi-film is dried together with the foliage and weeds that have been torn off on the multi-film. It will be in the state adhering to etc. The foreign matter adhering to the root portion 2 c is wound around the rotating portion of the earth dropping device (16, 17) or the rooting device 18 that acts on the root portion 2 c of the garlic 2 conveyed by the conveying device 12. When foreign matter is caught in the soil removal device (16, 17) or the root shaping device 18, the soil removal performance of knocking down the soil etc. of the soil removal device (16, 17) and the root alignment performance by the root shaping device 18 are obtained. Will be reduced. The reduction in the performance of these devices reduces the cutting ability in the root cutting device 14 and adversely affects the drying and adjustment operations after the garlic 2 is harvested.

  Therefore, according to the configuration provided with the multi-dropping device 100 as in the vegetable harvesting machine 1 according to the present embodiment, the contamination such as the multi-film and the foliage that are pulled up together with the excavated garlic 2 and attached to the root 2c. An object can be efficiently knocked down and removed by the multi-drop device 100. As a result, it is possible to prevent the mulch film (collapse mulch, thin mulch, etc.) and the foliage that cannot be peeled off before harvesting from being wound around the soil dropping device (16, 17) or the root shaping device 18. It is possible to prevent the performance from deteriorating. That is, the multi-dropping device 100 functions as a multi-film removal structure on the upper side of the conveyance, and the garlic 2 can be harvested by the vegetable harvesting machine 1 without peeling off the multi-film in advance.

  Moreover, in the vegetable harvester 1 of this embodiment, the multi dropping device 100 has the multi dropping rotation part 101 comprised with the elastic body as a part made to act on the root part 2c of the garlic 2. As shown in FIG. According to such a configuration, even when the garlic 2 is transported in a state of being deviated from the predetermined transport position and the multi-drop rotating part 101 contacts the bulb part 2a, the bulb part 2a is prevented from being damaged. be able to. In addition, the elastic deformation of the multi-drop rotating part 101 made of an elastic body allows the foreign matters such as the multi-film removed from the garlic 2 to escape, thus preventing the foreign matters from staying in the multi-drop device 100. can do.

  Further, the multi-drop rotating part 101 has a continuous shape in the direction of the rotation axis. According to such a configuration, since there are no irregularities or gaps in the rotation axis direction of the multi-drop rotating part 101, it is possible to prevent foreign objects such as multi-film from being caught in the multi-drop rotating part 101, Contaminants can be made difficult to wind. Further, in the multi-drop rotating part 101, the blade part 122 protruding from the base part 121 can obtain an action of hitting the root 2 c, and the outer diameter of the entire multi-drop rotating part 101 can be increased with respect to the base part 121. . Also from such a point, it is possible to prevent a foreign matter such as a multi-film from being wound around the multi-drop rotating unit 101. That is, the wrapping of the foreign matter such as the cut end of the multi-film occurs because the length of the foreign matter is longer than the circumference of the outer diameter of the target portion. The expanded shape formed of the blades 122 is continuous over the entire rotation axis direction, and the outer diameter is increased uniformly throughout. Therefore, a contaminant having a length equal to or less than the circumference of the outer diameter of the multi-drop rotating part 101 is obtained. Can be prevented, and the wrapping of impurities can be reduced.

  Moreover, in the vegetable harvesting machine 1 of this embodiment, the multi-drop rotating part 101 is provided so that it may act on the direction different from the conveyance direction by the conveying apparatus 12 with respect to the garlic 2 currently conveyed by the conveying apparatus 12. FIG. ing. Thereby, the soil dropping device (16, 17) or the rooted shape arranged on the transport lower side of the multi drop device 100 without causing the multi drop rotating unit 101 to fly foreign matters such as multi film to the transport lower side. A decrease in the performance of the device 18 can be prevented.

  If the transport direction of the garlic 2 by the transport device 12 and the direction of action of the multi-drop rotating part 101 on the garlic 2 coincide with each other, the multi-drop rotating part 101 knocks off multi-film fragments and weeds. In this case, the removed impurities will fly to the lower transport side. In such a case, the foreign matter blown off by the multi-dropping rotating unit 101 is caught in the earth dropping device (16, 17) or the rooting device 18, and the performance of each device may be lowered.

  Therefore, as described above, by making the direction of action of the multi-drop rotating part 101 different from the direction of transport of garlic 2, it is possible to avoid the foreign matter being thrown to the lower side of the transport, A decrease in performance can be prevented. Thereby, it becomes possible to obtain effectively the removal performance of the foreign substance by the multi dropping device 100.

  In particular, with respect to the direction of action of the multi-drop rotating part 101, the rotational direction of the multi-drop rotating part 101 acts in the direction facing the root 2c of the garlic 2 being transferred by the transfer device 12 as in this embodiment. A configuration in which the multi-drop rotating unit 101 is rotated in the forward direction (see FIG. 6, arrow X1) is employed. According to such a configuration, the multi-drop rotating part 101 acts so as to strike the garlic 2 coming from the front side from the rear side, so that the action of the multi-drop rotating part 101 can be relatively improved. it can. That is, in the action by the multi-drop rotating part 101, the action of conveying the garlic 2 by the conveying device 12 can be used effectively.

  Moreover, in the vegetable harvesting machine 1 of the present embodiment, the multi-drop rotating part 101 has a base part 121 and a plurality of blade parts 122 extending from the base part 121. According to such a configuration, the blade portion 122 can be made to continuously act on the root portion 2c of the garlic 2 by the rotation of the multi-drop rotating portion 101, so that the soil dropping action can be efficiently performed with a relatively simple shape. In addition to being able to be obtained, it is possible to easily obtain a shape that can easily prevent wrapping of impurities such as a multi-film.

  Moreover, in the vegetable harvester 1 of this embodiment, the height position of the multi dropping device 100 can be adjusted. According to such a configuration, for example, the height position of the multi-dropping device 100 can be changed depending on the size of the garlic 2 and the like, so that the operation of the multi-dropping device 100 can be reliably performed according to the size of the garlic 2 and the like. Can be obtained. That is, when obtaining the action of the multi-dropping device 100, versatility can be improved with respect to the types of vegetables that are the harvesting target by the vegetable harvesting machine 1.

  The configuration of the multi-dropping device 100 is not limited to the configuration of the present embodiment, and the transport device 12 can act on the root 2c of the garlic 2 being transported to remove contaminants such as multi-film. I just need it. Further, the direction of the rotation axis of the multi-drop rotating unit 101 is not limited to the left-right direction of the machine body as in the present embodiment, and may be, for example, a direction along the transport direction of the transport device 12.

(Modification 1 of multi-dropping device)

As shown in FIGS. 16 and 17, the multi-dropping device 100 </ b> A of this modified example is a direction parallel to the transport direction of the transport device 12 in the body plan view and substantially the transport direction of the transport device 12 in the body side view. A pair of left and right multi-drop rotating units 101 having a parallel direction as a rotation axis direction are provided. The pair of multi-drop rotating units 101 are provided symmetrically across the garlic 2 conveyance path.

  As described above, in the multi-dropping device 100A of the first modification, the multi-dropping rotation unit 101 sets the rotation axis direction to a direction parallel to the transport direction of the transport device 12 in plan view of the machine body. The multi-dropping device 100 </ b> A according to the first modification includes two multi-dropping rotation units 101 that are arranged side by side symmetrically with respect to the transport path of the transport device 12.

  The outer diameter, inter-axis distance, and phase of the pair of left and right multi-drop rotation units 101 are determined by the rotation of the blade unit 122 of one multi-drop rotation unit 101 (101A) and the blade unit 122 of the other multi-drop rotation unit 101 (101B). It is set so as to enter the range (within the rotation locus), that is, into the recess 123. Further, the rotation directions of the pair of left and right multi-drop rotating parts 101 are opposite to each other so that the root part 2c of the garlic 2 located between them is hit from the upper side to the lower side. That is, as shown in FIG. 16, the rotation direction of the multi-drop rotary part 101A located on the left side is clockwise (right rotation direction) when viewed from the front side (upper conveyance side) of the machine body (see the arrow K1), and on the right side. The rotation direction of the multi-drop rotating unit 101B positioned is counterclockwise (left rotation direction) (see arrow K2). With such a configuration, the root part 2c of the garlic 2 is alternately hit by the blade parts 122 of the left and right multi-drop rotating parts 101, and is reliably subjected to the action of knocking off foreign substances such as multi-films.

  As described above, in the multi-dropping device 100A of the first modification, the rotation directions of the two multi-dropping rotation units 101 are opposite to each other, and with respect to the root 2c of the garlic 2 being transferred by the transfer device 12. It is the direction of rotation acting from top to bottom.

  An example of a power transmission configuration for the multi-drop device 100A according to Modification 1 will be described. As shown in FIG. 17, each multi-drop rotating unit 101 is supported by a rotating shaft 202 whose axial direction is a direction along the inclination direction of the transport device 12. The rotating shaft 202 that supports each multi-drop rotating unit 101 receives the rotational power of the input shaft 203 along the horizontal direction of the machine body via bevel gears 204a and 204b. The input shaft 203 is accommodated in a cylindrical drive input case 205.
