Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a leaf cutter that mechanically cuts off the leaves of carrot.

[0002]

[Prior Art]

 Conventionally, the leaf cutting work in carrot harvesting has been performed manually, and the leaves of carrots are cut off one by one with a knife or pot after they have been pulled out from the field.

[0003]

[Problems to be solved by the device]

 However, since the artificial leaf cutting work of all harvested carrots is a labor-intensive task, there is a growing demand for mechanization. The purpose of the present invention is to make the carrot harvesting work laborious and easy by mechanizing the leaf cutting work.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a number of rollers which are aligned in a predetermined direction and rotate about each other by arranging them in parallel with each other with a predetermined gap formed between adjacent rollers and driving them to revolve. Constituting a transport device that rotates between adjacent rollers while transporting the ginseng above the transport device by elastic contact with the upper surface of the ginseng transported by the transport device In addition to arranging an aligning device that aligns with each other, a leaf cutting device that cuts off the leaves of carrots transported in an aligned state is provided at the lower side of the aligning device in the transport direction. It is characterized in that it is set in a tapered shape that becomes thinner toward the side.

[0005]

[Action]

 First of all, the harvested carrots are handed over to the aligning device in a state in which the directions of the leaves are aligned, and the carrots rotate between the rollers due to the transporting action of the transporting device consisting of many rotating rollers. It will be transported. Then, the carrots are aligned by one side of the carrier by the aligning action of the aligning device so that the carrots are aligned to the one end side, and then the carrots are transported to the leaf cutting device. Will be able to. In addition, since a predetermined interval is formed between the adjacent rollers, those narrower than this interval are allowed to drop, so that a sorting effect of dividing into a predetermined thickness can be exhibited. The aligning device moves the ginseng in the axial direction of the roller by elastically contacting the upper surface of the ginseng, that is, the means that the lateral transfer force acting on the ginseng is gentle and does not damage the ginseng (eg, rotation). Brushes, rubber pieces that reciprocate, etc.), but the carrots are transported while rotating by the rotation of the orbitally driven rollers themselves, and the action required for their movement in the longitudinal direction. This is possible because of the existence of a transporting device with a structure that requires only a small amount of force. This made it possible to align carrots with a small driving force without damaging them. By the way, since ginseng has a thick leaf side and a thin root side, it has an approximately inverted triangular shape. Therefore, when a general cylindrical roller is used, the top surface of the carrot body is inclined and the cut surface of the leaf is also inclined. However, in the present application, the roller is set to have a taper shape that becomes narrower toward one end side, so that the taper of the roller and the taper of the carrot cancel each other out so that the carrot transporting posture becomes a horizontal posture or a substantially horizontal posture. It is possible to make the cut surface of the leaf as close as possible to the cut surface. A means for suppressing the oblique cutting by arranging the leaf cutting device with respect to the axis of the roller may be considered, but this requires that the drive system of the leaf cutting device also be tilted, and the driving force transmission structure thereof. However, in the present invention, the drive system is advantageous in that it can be configured as a simple one that can be arranged horizontally.

[0006]

[Effect of the device]

 As a result, a series of leaf cutting work is mechanized, the human labor required for the leaf cutting work is drastically reduced, and the mechanization can increase the leaf cutting work speed and improve the working capacity. Can be provided as a preferable appearance in which the cuts of the leaves are along the upper surface of the carrot body with minimal damage to the carrot.

【Example】

 An embodiment of the present invention mounted on a carrot harvester will be described below with reference to the drawings. FIG. 1 and FIG. 2 show a carrot harvester in which a pre-pulling-out processing section A, a leaf cutting section B and a collecting section C are mounted on a traveling machine body D which can be traveled by a crawler traveling device 14. The pull-out pretreatment unit A is configured by mounting and supporting the landslide device 1, the pulling device 2, the lateral twisting transfer device 3, and the grounding roller 4 on the pretreatment frame 5, and the left-right direction is caused by the expansion / contraction operation of the lifting cylinder 6. It is possible to swing up and down around the fulcrum P. The leaf cutting unit (corresponding to a leaf cutting machine) B includes a transport device 7, an aligning device 8, a leaf cutting device 9, and a pretreatment cutter 10. The recovery section C is composed of a recovery container 13 which is erected from the body frame 11 and is pivotally attached to the recovery frame 12 so as to be swingable around the horizontal axis X 1.

The drawing pretreatment unit A will be described in detail. The landslide device 1 suspends a U-shaped disentangling member 16 in a front view from a support frame 15 erected from the pretreatment frame 5 so as to be rotatable about a horizontal axis Y, and a fulcrum P about a rotation axis. The pre-treatment frame 5 is equipped with an input pulley 18 which is interlocked with the counter pulley 17 and the upper and lower intermediate portions of the loosening member 16 and the input pulley 18 are interlocked by a short link 19 and a long link 20. The unraveling member 16 is oscillated back and forth in the ground by means of the crank mechanism 21, and the soil around the ginseng is collapsed so that the next extraction of ginseng can be facilitated. A cushioning material 20a is wound around the long link 20 so that a mud-removing operation that comes into contact with the carrot body transported by a lateral twisting transport device 3 described later can be performed without damaging the carrot. is there. The pulling device 2 is configured to have a pair of left and right rotating belts 23 with locking projections 22 that are opened in a forward C-shape in a plan view and tilted backward and upward in a side view. Together with the weeding tool 24, it acts to handle the leaves of the two-row carrot row and pull them upward. The lateral twist transfer device 3 includes a lifting transfer mechanism 3A and an auxiliary transfer mechanism 3B. The lifting / conveying mechanism 3A extends from the left and right lower pulleys 25 that share the upper and lower shaft axes Z of the pulling device 2 in an obliquely upward and downward direction, and the upper pulley 26 that has an axis parallel to the pulley axis Z. A pair of conveyor belts formed by winding the belt 27 are arranged close to each other. The auxiliary transport mechanism 3B is configured by providing a pair of left and right endless rotation bands formed by winding a belt 30 having a protrusion around upper and lower wheels 28 and 29 having a lateral axis, and is provided below the rear portion of the lifting and transporting mechanism 3A. It is located on the side. In other words, the carrots are lifted and transported diagonally upward and leftward in a hanging posture with the leaf portions being sandwiched between the left and right belts 27, 27, and the carrot body is lifted by the auxiliary transport mechanism 3B to remove the carrots. Change to a recumbent posture and transfer to the next leaf cutting part B.

Next, the leaf cutting section B will be described in detail. The transport device 7 includes a plurality of rotatable rollers 31 arranged side by side with a predetermined gap between adjacent rollers 31 and a chain link attached to the end portions of the plurality of rollers 31. 32 is wound around four front and rear sprockets 33, and the carrots sent from the lifting and conveying device 3 are rearwardly transferred in a recumbent posture. A guide member 34 that contacts the lower surface of the roller 31 in the upper roller portion is provided. When the chain 32 is driven to revolve in the direction of arrow A by driving the chain 32, the roller 31 that contacts the guide member 34 rotates counterclockwise. It can also rotate in the direction (arrow B in Fig. 1). The roller 31 is formed in a tapered shape (conical conical shape) that becomes thinner toward the leaf portion side of the carrot, and a collar 31a is attached to the left end thereof. It is possible for the main body of the carrot to come into contact with the collar 31a. The aligning device 8 is composed of a rotating brush 35 above the transporting device 7 and rotating around an inclined axis T which is inclined so that the front part is inclined to the right with respect to the axis V of the roller 31. It has a function of sequentially moving the leaf portion side to the flange 31a of the roller 31. In other words, the rotating brush 35 is elastically contacted with the upper surface of the carrot to generate a feeding force for forcibly transferring the carrot to the left in the figure, so that the carrot can be reliably brought into contact with the brim 31a and aligned. The leaf cutting device 9 thus configured is provided with a rotary blade 36 that rotates around the left and right axis at the rear part of the transport device 7, and is transferred in a predetermined cutting posture in which the carrot body is abutted on the collar 31a. Cut off the leaves of the carrots that come in. The pretreatment cutter 10 is driven and rotated about the horizontal axis, is installed at a position slightly left of the roller 31 in the front part of the transport device 7, and is a carrot leaf portion sent from the lifting transport device 3. By rough cutting, the leaves are expanded in all directions and grown so that the subsequent processes are not adversely affected.

The recovery unit C will be described in detail. The collection container 13 stores the carrots of which only the leaves are cut off. The empty collection container 13 is provided with a tension spring 37 for biasing the side wall 13a to an initial posture inclined around the horizontal axis X so that the side wall 13a serves as a sliding surface for carrots. Collection with progress of ginseng collection The elastic force of the tension spring 37 is set so that the collection container 13 swings around the horizontal axis X and automatically changes to the standing collection posture as the weight of ginseng increases. is there.

[Other Embodiments] As shown in FIG. 4, the roller 31 is arranged so as to be inclined upward to the right, and the axis T of the rotary brush 35 is also set in the front-rear direction, and the guide member 34 is It may be a leaf-cutting portion B constituted by a folding plate so as to form a drop transfer path for the cut leaf portion. As shown in FIG. 5, the roller 31 in the horizontal state is configured so that the position of the collar 31a in the roller shaft center direction can be adjusted and set (for example, the collar 31a is made of a rubber plate), and the cut-off length at the root portion of the leaf is set. It may be a leaf-cutting part B which is configured so that the height can be changed and set. It is also possible to construct a stationary type leaf-cutting machine consisting only of the leaf-cutting section B.
