Description

  The present invention relates to a soft vegetable harvester of the type that cuts the roots of soft vegetables such as spinach with a cutting blade and conveys them upward by a conveyor.

  Traditionally, the roots of soft vegetables (leafy vegetables) such as spinach and Japanese mustard were cut with a sickle by hand. However, cutting a large amount of vegetable roots manually with a sickle is a painful work for the operator and the work efficiency is low.

  Therefore, in order to mechanize the above work, a blade with a reciprocating motion in the longitudinal direction is attached to a frame having wheels, and the blade is driven by a power source, and the frame is pulled manually to cut the root of the vegetable. A traveling rooting machine that travels is proposed in Patent Document 1 below. Spinach whose roots have been cut by this root cutting machine is left in the field, and later, they are collected by human power.

  Further, Patent Document 2 below proposes a spinach harvester that digs up spinach with a blade and transports the spinach toward the rear while being sandwiched between a pair of left and right conveyors. Since the spinach digged up by this digging blade is conveyed diagonally upward with its left and right sandwiched between conveyors, the leaves are easily damaged. Also, the spinach that is dug and transported is one, and the working efficiency is not high.

  In the present invention, when cutting the roots of soft vegetables (leaf vegetables) such as spinach, komatsuna, green onion and mizuna growing on the ground and then transporting them upward by a conveyor, the conveyor will not damage the leaves. Another object is to provide a soft vegetable harvester with a simple structure.

  In order to achieve the above object, a soft vegetable harvesting machine according to the present invention includes a traveling unit for advancing the airframe, and a cutting unit that cuts the roots of a plurality of strains of the vegetable vegetable substantially simultaneously with a cutting blade that reciprocates left and right. A pair of a soft vegetable transport unit that transports a plurality of soft vegetables whose roots have been cut with the cutting blade to the rear, and an inclined portion that gradually narrows the transport path of the soft vegetable transport unit toward the rear, toward the front It consists of a guide cover.

The traveling section can be a traveling crawler or a wheel that rotates with an engine mounted on the machine frame.
The cutting part is composed of a cutting blade having a single blade for cutting the roots of soft vegetables such as spinach from a certain depth underground, and a mechanism for reciprocating the cutting blade from side to side. This cutting blade has a width that can cut the roots of a plurality of soft vegetables arranged side by side almost simultaneously.
A soft vegetable conveyance part consists of a belt conveyor which receives the soft vegetable which cut the root with the cutting blade, and conveys it back. The belt conveyor may be made of a sheet, or a material with stitches may be used. If a material with stitches is used, the soil attached to the soft vegetables in the middle of conveyance can be removed by vibration. Further, a brush for forcibly removing the soil may be provided to face the belt conveyor.
The guide cover forms vertical guide walls on both the left and right sides of the belt conveyor constituting the soft vegetable transport unit, and the belt conveyor and the guide cover form a transport path for the soft vegetables. This conveyance path is the widest at the front end, and gradually becomes narrower as it advances backward. As a result, a plurality of strains of soft vegetables transferred from the cutting blade onto the belt conveyor can be brought closer to the center side during transportation.
A plurality of strains of soft vegetables gathered in the center on the belt conveyor are in a state where the leaves and the leaves of each other are intertwined, and are conveyed rearward on the conveying path while maintaining the initial standing position.

  According to the present invention, a plurality of rows (for example, four rows) of soft vegetables that have been cut and harvested at a time can be transported backward while maintaining a certain posture without being tightened by a transport belt. The harvesting operation with high work efficiency is possible without damaging the container during transportation.

  A soft vegetable harvesting machine 1 according to the present invention is a self-propelled harvesting machine in which a traveling crawler 4 is attached to a machine frame 2 and an engine 3 as a driving source for driving the traveling crawler 4 is mounted on the machine frame 2.

  A cutting blade mounting beam 5 extends forward from the front of the machine frame 2 in the traveling direction. A movable frame 61 that can reciprocate in the left-right direction with respect to the beam 5 is attached to the cutting blade mounting beam 5. A flat cutting blade 6 is fixed to the lower end of the movable frame 61. The reciprocating motion of the movable frame 61 is performed by a cutting blade driving motor 62 mounted on a mounting base 51 fixed to the tip of the cutting blade mounting beam 5.

  Specifically, an eccentric cam 63 is fixed to the output shaft of the cutting blade driving motor 62, and a connecting rod 64 is stretched between the eccentric cam 63 and the movable frame 61. Accordingly, when the power supply 13 (FIG. 1) mounted on the rear part of the machine frame 2 is turned on and the cutting blade drive motor 62 is rotated, the eccentric cam 63 rotates and the connecting rod 64 reciprocates, so that the movable The cutting blade 6 fixed to the frame 61 and the movable frame 61 also reciprocates in the left-right direction with respect to the cutting blade mounting beam 5.

  As shown in FIG. 1, the cutting blade 6 cuts the root of the spinach 7 by reciprocating in the left-right direction while being slightly inclined forward and entering the ground. FIG. 2 shows an example in which the roots of spinach 7 for four strains arranged side by side with one cutting blade 6 are cut almost simultaneously. As apparent from the top view of FIG. 2, the front end edge (blade portion) of the cutting blade 6 has a substantially V-shape in which the front center portion slightly protrudes forward from the left and right end portions.

  From the left and right sides of the machine casing 2, short support columns 21 and 21 extend forward, and long support columns 22 and 22 extend rearward and upward. A conveyor support frame 81 that supports the belt conveyor 8 is fixed to the upper ends of these columns 21, 21, 22, and 22. The belt conveyor 8 is stretched around a drive wheel 82 and driven wheels 83, 84, 85 that are rotatably attached to the conveyor support frame 81. In the belt conveyor 8, the section from the front-end driven wheel 85 to the rear-side driven wheel 83 takes an inclined posture that gradually increases toward the rear, and the section from the driven wheel 83 to the drive wheel 82 is horizontal. Taking a posture.

  The drive wheels 82 are driven by a conveyor drive motor 87 mounted on the rear side of the machine casing 2. The power source of the conveyor driving motor 87 is the power source 13 and is shared with the power source of the cutting blade driving motor 62. When the power supply 13 is turned on and the conveyor driving motor 87 is driven, the driving wheels 82 are rotated through power transmission means (not shown), and the belt conveyor 8 is rotated.

  Furthermore, guide covers 9 and 9 having fixed heights are attached to the left and right sides of the belt conveyor 8 at the upper ends of the columns 21, 21, 22, and 22, respectively. The belt conveyor 8 and the guide covers 9 and 9 constitute a conveying route for soft vegetables. Since the inclined portions 91 and 91 are formed at the front portions of the guide covers 9 and 9, respectively, as shown in FIG. 2, this conveyance path is the widest at the front end portion, and thereafter, gradually, as it advances backward. Becomes narrower. As a result, a plurality of strains of soft vegetables that have passed over the belt conveyor 8 beyond the cutting blade 6 are gradually brought closer to the center by the inclined portions 91 and 91. And the soft vegetable which passed the conveyance path | route between this inclination part 91 and the inclination part 91 advances back the part where guide covers 9 and 9 become parallel hereafter.

  When an operator drives the soft vegetable harvester 1 forward while holding the handle 12, the roots of spinach 7 separated by the divider 13 in the front of the machine (four in the example of FIG. 1) reciprocate left and right. The moving cutting blade 6 cuts almost simultaneously. Then, the spinach 7 whose root has been cut passes over the cutting blade 6 and is transferred to the front portion of the belt conveyor 8.

  Since the inclined portions 91 of the guide cover 9 are fixedly arranged in the form of a vertical wall on both front sides of the belt conveyor 8, a plurality of strains (four in the example of FIG. 2) whose roots are cut almost simultaneously. ) As the belt conveyor 8 travels, the spinach is guided rearwardly by the inclined portion 91 of the guide cover 9 and is gradually moved toward the center, and is sent backward by the belt conveyor 8.

  In this way, the multiple spinach 7 is gradually brought to the center, and the adjacent spinach leaves are entangled with each other, and these spinach support each other and maintain the posture when transferred to the belt conveyor 8. In other words, the belt conveyer 8 conveys the paper between the left and right guide covers 9 and 9 while maintaining the posture with the leaves up and the roots down without being overturned or inverted. The spinach that has been sent to the rear part of the belt conveyor 8 (the horizontal part between the driven wheel 83 and the drive wheel 82) is taken out by the operator operating the soft vegetable harvesting machine 1 to the field. Store in a container (not shown).

  It is a side view of one Example of the soft vegetable harvester by this invention.   It is a top view of the soft vegetable harvester of FIG.   It is a front view of the soft vegetable harvester of FIG.
