That is, the attachment member 50 is located on the left side of the stem cutting fixed blade 42 in the rear view and is disposed so as not to intersect the conveying path 10 of the stem of the onion 2.
Therefore, the attachment member 50 does not cross the conveyance path 10 from the root cutting rotary blade 21 of the root cutting part 20 to the stem cutting rotary blade 41 of the stem cutting part 40, and the onion after cutting is attached to the attachment member 50. It is possible to prevent the stem of No. 2 from being wound and to ensure the cutting of the stem of the onion 2.

A tooth portion 33 is provided on the periphery of the stem cutting rotary blade 41. The configuration of the tooth portion 33 is arbitrary, but at least the rear side in the rotational direction of the groove-shaped tooth chamber 37 that is provided at the peripheral edge 34 of the stem cutting rotary blade 41 and that is recessed toward the axial center direction of the stem cutting rotary blade 41. A tooth surface 38 is formed on the surface (FIG. 20).
Therefore, when the stem cutting rotary blade 41 rotates, the tooth surface 38 comes into contact with and cuts so as to be hooked on the stem of the onion 2, and at the time of this cutting, the stem is sent to the lower side in the conveying direction.
In this case, the number of the tooth portions 33 is arbitrary, and a plurality of the tooth portions 33 may be provided at a predetermined interval on the peripheral edge 34 of the stem cutting rotary blade 41. However, when a large number is provided, the cutting ability is improved accordingly.
FIGS. 21-23 shows other embodiment of the tooth | gear part 33 of the stem cutting rotary blade 41, and inclines so that the peripheral edge 34 of the rotation direction rear side of the tooth surface 38 may become low as it reaches the rear side of a rotation direction. A tooth surface 33 is formed in a triangular shape by the connection surface 39 and the tooth surface 38, and the tooth portion 33 is continuously formed to form a so-called saw-toothed shape.

Therefore, when the stalk cutting rotary blade 41 rotates, the tooth surface 38 acts in a so-called saw-tooth shape, and when cutting the stalk of the onion 2, it can be expected to send the stalk to the lower side in the conveying direction. Prevents stem clogging of transported onion 2.
That is, the tooth portion 33 forms the inner periphery on the rear side in the rotation direction of the tooth chamber 37 as a tooth surface 38 and the inner periphery on the front side in the rotation direction of the tooth chamber 37 as a connection surface 39.
Thereby, when the stem cutting rotary blade 41 rotates, the tooth portion 33 comes into contact with and cuts the tooth surface 38 of the tooth portion 33 so as to push from the rear side to the front side of the stem of the onion 2 being conveyed. As a result, the tooth portion 33 of the stem cutting rotary blade 41 can also be expected to have an effect of feeding the stem to the lower side in the transport direction when cutting the stem of the transport onion 2, thereby preventing the stem clogging of the transport onion 2 in the stem cutting portion 40. .

Further, the tooth portion 33 of the pedicle cutting rotary blade 41 has a length T from the groove bottom (deepest portion) of the tooth chamber 37 to the tip (outer end) of the connection surface 39, and the tooth surface 38 from the bottom of the tooth chamber 37. It forms so that it may become longer than the length t to a front-end | tip (outer end) (FIG. 23).
Thereby, when the stem cutting rotary blade 41 rotates, the tooth portion 33 acts in a sawtooth shape, and the tooth surface 38 of the rotating tooth portion 33 acts so as to bite into the stem of the onion 2. When cutting the stalk of the onion 2, it acts to send the stalk to the lower side in the conveying direction, can reliably cut the stalk of the conveying onion 2, and the stem clogging of the conveying onion 2 in the stalk cutting unit 40 is generated. To prevent.
The inclination angle from the groove bottom of the tooth chamber 37 to the tip (outer end) of the tooth chamber 37 of the tooth portion 33 and the connection surface 39 is arbitrary, but the tip (outside) of the tooth surface 38 from the groove bottom of the tooth chamber 37 is arbitrary. The inclination angle S to the end) is formed so as to be steeper than the inclination angle s from the groove bottom of the tooth chamber 37 to the tip (outer end) of the connection surface 39 (FIG. 23).

Therefore, when the stem cutting rotary blade 41 rotates, the tooth portion 33 acts like a sawtooth, and the tooth surface 38 of the rotating tooth portion 33 acts so as to bite into the stem of the onion 2, thereby cutting the stem of the conveying onion 2 While ensuring, the effect | action which sends the stem of the conveyance onion 2 to the lower side of the conveyance direction can also be expected.
In other words, the tooth portion 33 includes one tooth surface 38 having a steep inclination angle with respect to the radial line L passing through the axis of the stem cutting rotary blade 41 and a connection surface 39 having a gentle inclination angle with respect to the radial line L. The tooth part 33 is formed continuously, and the stalk cutting rotary blade 41 is configured (FIG. 23).
Therefore, the tooth surface 38 of the rotating stalk cutting rotary blade 41 acts so as to bite into the stalk of the onion 2, and when the stalk cutting blade 41 cuts the stalk of the onion 2, the stalk is sent to the lower side in the conveying direction. The action can be expected, the stem of the onion 2 being conveyed can be cut reliably, and the stagnation of the onion 2 in the guiding part 55 for guiding the onion 2 to the stem cutting part 40, which will be described later, can be prevented.

That is, since the guiding unit 55 guides the onion 2 to the stem cutting unit 40, if the stem of the onion 2 is not immediately cut by the stem cutting unit 40, the transport onion 2 stagnates at the stem cutting unit 40. However, the stagnation of the conveying onion 2 is prevented by the action of feeding the stem of the onion 2 being cut to the lower side in the conveying direction by the tooth surface 38 of the tooth portion 33 of the stem cutting rotary blade 41.
FIG. 24 shows another embodiment of the tooth portion 33 of the stem cutting rotary blade 41. A tooth surface 38 is formed on the rear side in the rotation direction of the tooth chamber 37 formed in a U shape, and the rotation of the tooth chamber 37 is performed. An inner surface 39A is formed on the front side in the direction, the tooth surface 38 and the outer end of the inner surface 39A are connected by a peripheral edge 34, and the inclination from the groove bottom of the tooth chamber 37 to the tip (outer end) of the tooth surface 38 is a tooth chamber. 37 is inclined so as to be located on the front side in the rotation direction from the groove bottom to the tip.
Therefore, the contact pressure can be increased on the stem of the onion 2 on the tooth surface 38, and the stem of the hard onion 2 immediately after harvesting can be reliably cut.

FIG. 25 shows another embodiment of the tooth portion 33 of the stem cutting rotary blade 41, and the tooth chamber 37 and the tooth surface 38 are formed with a receding angle with respect to the radius line L.
Therefore, when the stem of the onion 2 that has entered the conveyance path 10 between the stem cutting fixed blade 42 and the stem cutting rotary blade 41 enters, the rotation of the tooth portion 33 of the stem cutting rotary blade 41 does not become an entry resistance. The onion 2 stems can be transported satisfactorily, and the contact pressure of the tooth surface 38 to the onion 2 stems can be increased to reliably cut the stems of the hard onion 2 immediately after harvesting.
Therefore, even if the inclination of the tooth surface 38 is inclined so as to be located on the front side in the rotation direction from the groove bottom to the tip of the tooth chamber 37, the tooth surface 38 of the rotating stalk-cutting rotary blade 41 is the stem of the onion 2. The contact pressure can be increased on the stem of the onion 2 on the tooth surface 38, and the stem of the hard onion 2 immediately after harvesting can be reliably cut.

Thus, a guiding portion 55 for guiding the onion 2 to the stalk cutting rotary blade 41 is provided between the root cutting rotary blade 21 of the root cutting unit 20 and the stalk cutting rotary blade 41 of the stalk cutting unit 40. The guide portion 55 is provided with a pair of left and right shaft bar-like guide bodies 56 that are inclined so that the rear side becomes higher and the front side becomes lower.
Therefore, the onion 2 is guided so that the distance between the holding position of the stem by the conveying belt 5 and the onion 2 main body is increased by the pressing action of the guide body 56 in addition to its own weight, and reaches the stem cutting portion 40. Therefore, the stems of each onion 2 can be cut into the same length, and the preparation processing accuracy of the onion 2 can be improved.

In addition, the guiding unit 55 can horizontally arrange the conveying belt 5 of the conveying unit 4, and the outer shape of the side view of the bulb vegetable preparation machine can be made into a quadrangular shape. Transport and storage can be facilitated.
Therefore, the guide unit 55 may be installed so that the onion 2 can be guided to the conveyance path 10 toward the stem cutting unit 40, and the configuration thereof is arbitrary, but the rear end of the guide body 56 is attached to the left and right attachment members 57. The mounting members 57 are respectively mounted on the left and right frames 45 of the fuselage frame 1.
The front end of the guide body 56 is positioned forward of at least the cutting portion between the stem cutting rotary blade 41 and the stem cutting fixed blade 42 of the stem cutting portion 40 and is a free end that is cut.

That is, the guide body 56 is supported in a cantilever state by the mounting member 57.

The discharge chute 59 is formed in the horizontal part 60 below the stem cutting part 40, and is provided with an inclined surface 61 that is inclined outwardly from a predetermined position of the horizontal part 60 in the left-right direction.
Further, the rear end of the horizontal portion 60 of the discharge chute 59 is formed in an extension portion 62 that extends backward from the rear edge of the inclined surface 61.
The extension part 62 prevents the onion 2 cut by the stem cutting part 40 from falling outside the machine behind the discharge chute 59 when it falls.

Therefore, the extension part 62 of the discharge chute 59 is extended to the vicinity of the support member of the root cutting part 20.
Further, a stem discharge chute 65 is provided in front of the stem cutting section 40, and the stem discharge chute 65 faces the stem discharge port 66 of the bulb vegetable preparation machine.
In addition, a drop derivative 68 that guides the onion 2 whose stem has been cut by the stem cutting unit 40 to the discharge chute 59 is provided below the stem cutting unit 40. The fall derivative 68 has a guiding surface (reflecting surface) 69 inclined downward in front of the side view, and is attached to the front moving member 44.
Therefore, when the onion 2 whose stem has been cut by the stem cutting unit 40 falls, the fall derivative 68 induces the fall into the discharge chute 59, thereby preventing the onion 2 from falling outside the apparatus.

That is, the drop derivative 68 coupled with the extension portion 62 of the discharge chute 59 induces the onion 2 to drop to the discharge chute 59 and prevents it from falling outside the machine.
Thus, the passive pulley 6 and the drive pulley 7 of the conveyor belt 5 are mounted on a flat plate-like upper frame 70 provided in the machine frame 1, and the upper frame 70 is divided into left and right parts, A stalk movement path communicating with the conveyance path 10 in the vertical direction is formed between the upper frames 70, and the pair of conveyance belts 5 move above the stalk movement path.

In front of the supply gap 72, a belt guide 75 is provided to urge the left and right transport belts 5 to elastically contact each other so that the left and right transport belts 5 can clamp the stems of the onion 2. The belt guide 75 includes a pair of left and right guide bodies 76 that are long in the moving direction.
One of the left and right guide bodies 76 on the rear side is fixed to the upper frame 70 and the other is movably attached in the crossing direction, and is urged by the spring 77 so as to elastically contact the fixed guide body 76. The configuration.
Therefore, the clamping force of the conveying belt 5 can be adjusted, and the configuration of the belt guide 75 can be simplified.

That is, when the stem of the onion 2 is supplied between the conveying belts 5, it is necessary to release the pair of conveying belts 5 that are in elastic contact with each other. 76 is moved to the outside so that the stem of the onion 2 can be supplied between the conveyor belts 5.
The left and right guide bodies 76 on the front side are each mounted so as to be movable in the crossing direction, and are urged by a spring 77 so as to elastically contact each other.
Therefore, the onion 2 is reliably conveyed from the root cutting part 20 to the stem cutting part 40.
In this case, the left and right guide bodies 76 on the front side are biased by the pair of front and rear springs 77 so that the left and right transport belts 5 elastically contact each other, but the rear spring 77A is biased by the front spring 77B. Set strongly.

That is, when the pressing force of the guide body 56 of the guide portion 55 increases the holding force of the rear portion of the guide body 76 that acts on the stem of the onion 2, the stem is shredded and discharged before being cut by the stem cutting portion 40. Since it falls on the chute 59, it is sufficient to set the elasticity so as to ensure the clamping force necessary for conveyance. On the contrary, in the front part of the guide body 76, the stem cut by the stem cutting part 40 is prevented from falling. The clamping force is increased.
Therefore, mixing of stems into the onion 2 group discharged by the discharge chute 59 can be prevented.
Thus, the support legs 3 that support the body frame 1 are configured by providing a pair of left and right leg portions 80 at the front and rear, and the front side support legs 3A and the rear side support legs 3B are respectively rotatable so as to be rotatable.

(Operation of the embodiment)
The present invention has the above-described configuration. When the main body is supplied with the stem of the onion 2 to the supply port 11 of the bulb vegetable preparation machine supported by the support leg 3, the stem of the onion 2 is transported by a pair of transports of the transport unit 4. The belt 5 is sandwiched between the belts 5 and transported toward the end side by the transport belt 5.
Since the root path 15 for extending the root of the onion 2 is provided in the transport path 10 in front of the supply port 11, the onion 2 is in a state where the stem is sandwiched between the rotating left and right rollers 16 and the blade material 17. Then, it is sandwiched from both the left and right sides and is conveyed while being rubbed downward. During the conveyance, the excess epidermis adhering to the surface of the main body of the onion 2 is removed, and then the root of the onion 2 is stretched downward.

Since the conveyance path 10 in front of the root stretcher 15 is provided with a root cutting part 20 for cutting the root of the onion 2 stretched by the root stretcher 15, the root cutting rotary blade 21 and the root of the root cutting part 20 are provided. The root of the onion 2 is cut by the fixed cutting blade 22.
The root cutting fixed blade 22 is fixedly attached to an attachment member 24, and the attachment member 24 is attached to a fixed side attachment member 26 provided on the attachment member 23 by a shaft 25 so as to be vertically movable and rotatable (rotatable). The fixed blade support mechanism 35 is configured by including the mounting member 24 to which the root cutting fixed blade 22 is mounted and the fixed side mounting member 26, and the fixed blade support mechanism 35 is a root cutting rotary blade based on the root cutting fixed blade 22. 21, the fixed blade support mechanism 35 does not cross the transport path 10 through which the roots of the onion 2 cut by the root cutting unit 20 and the cutting waste of the roots are transported. It is possible to prevent the cutting chips of the roots from being wound around the blade support mechanism 35, and to ensure the cutting of the roots of the onion 2.

That is, the mounting member 24 and the fixed-side mounting member 26 are located on the left side of the fixed blade root cutting rotary blade 21 and are arranged so as not to intersect with the conveying path 10 of the root of the onion 2. It is possible to prevent the cutting waste of the roots from being wound around, and to ensure the cutting of the roots of the onion 2.
Therefore, it is possible to suppress the retention of foreign matters such as cutting waste of the root of the onion 2 in the bulb vegetable preparation machine, the preparation process can be performed continuously, and the working efficiency can be improved.
Further, the shaft 25 to which the root cutting fixed blade 22 is attached is attached to the support member 27, and the support member 27 is attached to the fixed side attachment member 26 by the height adjustment shaft 28 so that the height can be adjusted. When the shaft 28 is rotated, the support member 27 is integrally moved up and down 26 to adjust the height of the root cutting fixed blade 22 relative to the root cutting rotary blade 21.

Therefore, the cutting edge height of the root cutting fixed blade 22 and the height of the root cutting rotary blade 21 can be matched at a predetermined height, and the cutting performance can be improved.
In addition, since the cutting edge angle of the root cutting fixed blade 22 can be changed by the adjustment dial 32, the tip of the root cutting fixed blade 22 is moved up and down to adjust the contact surface pressure against the root cutting rotary blade 21 as well as the root cutting rotary blade. The inclination angle of the front end surface of the root cutting fixed blade 22 with respect to 21 can be adjusted, and even the root of the soft onion 2 can be cut reliably and the cutting performance can be improved.
Since the conveyance path 10 in front of the root cutting part 20 is provided with a stem cutting part 40 for cutting the stem of the onion 2 whose root has been cut by the root cutting part 20, the onion being conveyed by the conveying belt 5. The two stems (leaves) are automatically cut by the stem cutting rotary blade 41 and the stem cutting fixed blade 42 of the stem cutting unit 40.

In this case, the stem cutting rotary blade 41 is attached to the attachment member 43, the attachment member 43 is attached to the front moving member 44 provided on the upper front side of the airframe frame 1 so as to freely move up and down, and both the left and right sides of the front moving member 44 are on the airframe frame. -Since the front moving member 44 is moved up and down with respect to the fuselage frame 1 with the adjusting screw 46 to adjust the cutting height of the stem of the onion 2, A uniform stem portion having a predetermined length can be left with respect to the main body of the onion 2, and the onion 2 can be treated beautifully.
The stem cutting fixed blade 42 is mounted in a fixed state on the base of the stem cutting fixed blade 42 to the mounting member 50, the mounting member 50 is mounted on the mounting member 51, the mounting member 51 is mounted on the front moving member 44, and the mounting member 50 is Since the stem cutting blade 42 is arranged on the opposite side of the stem cutting rotary blade 41 with respect to the stem cutting fixed blade 42, the mounting member 50 is located on the left side of the stem cutting fixed blade 42, and does not intersect with the stem conveyance path 10 of the onion 2. Can be arranged.

Therefore, the stem cut by the stem cutting unit 40 moves toward the end of the conveyance path 10 without contacting the mounting member 50, and the debris of the cut stem of the onion 2 is collected around the stem cutting unit 40. It is possible to prevent this, and the preparation work can be performed continuously, the maintenance can be facilitated, and the work efficiency can be improved.
At the periphery of the stem cutting rotary blade 41, at least on the rear side of the rotational direction of the groove-shaped tooth chamber 37 provided at the periphery 34 of the stem cutting rotary blade 41 and recessed toward the axial direction of the stem cutting rotary blade 41. Since the tooth portion 33 formed by forming the tooth surface 38 is provided, when the stem cutting rotary blade 41 rotates, the tooth surface 38 comes into contact with the stem of the onion 2 and cuts, and the stem is cut during the cutting. Is sent to the lower side in the transport direction.

  In another embodiment of the tooth portion 33 of the stem cutting rotary blade 41 of FIG. 21, the connecting surface 39 and the teeth are inclined so that the peripheral edge 34 on the rear side in the rotation direction of the tooth surface 38 becomes lower as it reaches the rear side in the rotation direction. Since the tooth portion 33 is formed in a triangular shape by the surface 38, and the tooth portion 33 is continuously formed to have a so-called saw-toothed shape, the tooth surface 38 acts in a so-called drag saw shape when the stem cutting rotary blade 41 rotates. Moreover, when cutting the stem of the onion 2, an effect of sending the stem to the lower side in the conveying direction can also be expected, and the occurrence of stem clogging of the conveying onion 2 in the stem cutting unit 40 is prevented.

  That is, since the tooth part 33 is formed with the inner circumference on the rear side in the rotation direction of the tooth chamber 37 as a tooth surface 38 and the front side in the rotation direction of the tooth chamber 37 is formed as a connection surface 39, the tooth part 33 is rotated through a stem. When the blade 41 rotates, the tooth surface 38 of the tooth portion 33 comes into contact with and cuts from the rear side to the front side of the stem of the onion 2 being conveyed, and as a result, the tooth portion of the stem cutting rotary blade 41 is cut. 33 can also be expected to have an effect of sending the stem to the lower side in the conveying direction when cutting the stem of the conveying onion 2, and prevents the occurrence of clogging of the conveying onion 2 in the stem cutting unit 40.

  Further, the tooth portion 33 of the pedicle cutting rotary blade 41 has a length T from the groove bottom (deepest portion) of the tooth chamber 37 to the tip of the connection surface 39 and a length from the bottom of the tooth chamber 37 to the tip of the tooth surface 38. Since it is formed to be longer than the length t, when the stem cutting rotary blade 41 rotates, the tooth portion 33 acts like a sawtooth, and the tooth surface 38 of the rotating tooth portion 33 bites into the stem of the onion 2. When the stem of the onion 2 is cut by the stem cutting rotary blade 41, the stem is sent to the lower side in the carrying direction, and the stem of the carrying onion 2 can be cut reliably. The stem clogging of the conveying onion 2 in the part 40 is prevented.

  The inclination angle from the groove bottom of the tooth chamber 37 to the tip of the tooth chamber 37 of the tooth portion 33 and the connection surface 39 is arbitrary, but the inclination angle S from the groove bottom of the tooth chamber 37 to the tip of the tooth surface 38 is When formed so as to be steeper than the inclination angle s from the groove bottom of the tooth chamber 37 to the tip of the connecting surface 39, the tooth portion 33 acts like a saw blade when the stem cutting rotary blade 41 rotates, The tooth surface 38 of the rotating tooth portion 33 acts so as to bite into the stem of the onion 2, ensuring the cutting of the stem of the conveying onion 2, and the effect of sending the stem of the conveying onion 2 to the lower side in the conveying direction can also be expected. .

  In other words, the tooth portion 33 includes one tooth surface 38 having a steep inclination angle with respect to the radial line L passing through the axis of the stem cutting rotary blade 41 and a connection surface 39 having a gentle inclination angle with respect to the radial line L. If this tooth part 33 is formed continuously to form the stem cutting rotary blade 41, the tooth surface 38 of the rotating stem cutting rotary blade 41 acts so as to bite into the stem of the onion 2, When cutting the stalk of the onion 2 with the cutting rotary blade 41, it is possible to expect the action of sending the stalk to the lower side in the conveying direction, and the stalk of the onion 2 being conveyed can be reliably cut, which will be described later. The stagnation of the onion 2 in the guiding part 55 that guides 2 to the stem cutting part 40 can be prevented.

That is, since the guiding unit 55 guides the onion 2 to the stem cutting unit 40, if the stem of the onion 2 is not immediately cut by the stem cutting unit 40, the transport onion 2 stagnates at the stem cutting unit 40. However, the stagnation of the conveying onion 2 is prevented by the action of feeding the stem of the onion 2 being cut to the lower side in the conveying direction by the tooth surface 38 of the tooth portion 33 of the stem cutting rotary blade 41.
In another embodiment of the tooth portion 33 of the stem cutting rotary blade 41 of FIG. 24, a tooth surface 38 is formed on the rear side of the rotation direction of the tooth chamber 37 formed in a U shape, and the rotation direction of the tooth chamber 37 is determined. An inner side surface 39A is formed on the front side, the tooth surface 38 and the outer end of the inner side surface 39A are connected by the peripheral edge 34, and the inclination from the groove bottom of the tooth chamber 37 to the tip (outer end) of the tooth surface 38 is increased. The tooth surface 38 is inclined so as to be located on the front side in the rotational direction from the groove bottom to the tip of the tooth chamber 37 because the tooth surface 38 is inclined on the front side in the rotational direction from the groove bottom to the tip. Even so, the tooth surface 38 of the rotating stalk cutting rotary blade 41 acts so as to bite into the stalk of the onion 2, and the contact pressure can be increased on the stalk of the onion 2 of the tooth surface 38, which is hard immediately after harvesting. The stalk of the raw onion 2 can be cut reliably.

Thus, between the root cutting rotary blade 21 of the root cutting part 20 and the stem cutting rotary blade 41 of the stem cutting part 40, a guiding part 55 for guiding the onion 2 to the stem cutting rotary blade 41 is provided, and the guiding part 55 Is provided with a pair of left and right shaft rod-shaped guide bodies 56 that are inclined so that the rear side is higher and lower toward the front side, so that the onion 2 cut by the root cutting unit 20 has a stem on the conveying belt 5. In the clamped state, the guide body 56 abuts and moves forward while descending, and the stem cutting unit 40 cuts the stem.
Therefore, the stems of each onion 2 can be cut into the same length, and the preparation processing accuracy of the onion 2 can be improved.

Further, since the main body of the onion 2 that is moving horizontally by the conveying belt 5 of the conveying unit 4 can be lowered to the position of the stem cutting rotary blade 41 of the stem cutting unit 40 by the guiding unit 55, the conveying unit 4. The conveyor belt 5 can be arranged horizontally, the external shape of the bulb vegetable preparation machine can be made into a square shape, and the conveyance and storage of the bulb vegetable preparation machine can be facilitated. it can.
In addition, since the guide portion 55 is attached to the attachment members 57 respectively attached to the left and right frames 45 of the airframe frame 1 and is supported in a cantilever state by the attachment members 57, The support structure of 55 and the guide | induction part 55 can be arrange | positioned so that the conveyance path 10 may not be crossed, interference with the stem of the onion 2 can be prevented, and the reliability of the cutting process of a stem can be improved.

  Thus, below the stem cutting unit 40, there is provided a discharge chute 59 that receives the onion 2 cut by the stem cutting unit 40 and guides it to the discharge outlet 58 of the bulb vegetable preparation machine. 60 and an inclined surface 61 which is inclined to the outside, and the rear end of the horizontal portion 60 of the discharge chute 59 is formed as an extension portion 62 extending rearward from the rear edge of the inclined surface 61. 62 prevents the onion 2 cut by the stem cutting part 40 from falling outside the machine behind the discharge chute 59 when it falls.

  Below the stalk cutting part 40 is provided a drop derivative 68 that guides the onion 2 whose stem has been cut by the stalk cut part 40 to the discharge chute 59, and the drop derivative 68 has a guiding surface guide surface 69 that is inclined downwardly as viewed from the side. Therefore, when the onion 2 whose stem has been cut by the stem cutting part 40 falls, the drop derivative 68 guides the drop direction toward the discharge chute 59 substantially downward, and the onion 2 Can be prevented from falling outside the machine.

  Thus, the passive pulley 6 and the drive pulley 7 of the conveyor belt 5 are mounted on a flat plate-like upper frame 70 provided in the machine frame 1, and the upper frame 70 is divided into left and right parts, A stalk movement path stalk movement path communicating with the conveyance path 10 in the vertical direction is formed between the upper frames 70, and the passive pulley 6 disposed on the inlet side (rear side / start end side) of the conveyance path 10 is predetermined in the left-right direction. The supply gap 72 which can arrange | position and arrange | position the space | interval and can supply the stem of the onion 2 between the left and right conveyance belts 5 is formed, and the left and right conveyance belts 5 can sandwich the stem of the onion 2 before the supply gap 72. As described above, the belt guide 75 that biases the left and right conveying belts 5 to elastically contact each other is provided, so that the stems of the onion 2 are sandwiched and conveyed by the left and right conveying belts 5.

The belt guide 75 includes a pair of left and right guide bodies 76 that are long in the moving direction, and one of the front and rear root cutting rotary blades 21 is fixed to the upper frame 70. On the other hand, the other is attached so as to be movable in the crossing direction, and is configured to elastically abut against the fixed guide body 76 by a spring 77, so that the holding force of the conveying belt 5 can be adjusted, and The configuration of the belt guide 75 can be simplified.
That is, when the stem of the onion 2 is supplied between the conveying belts 5, one of the pair of conveying belts 5 which are in elastic contact with each other can escape and escape, and the stem of the onion 2 can be clamped appropriately and reliably.

The left and right guide bodies 76 on the front side of the belt guide 75 are mounted so as to be movable in the crossing direction and are urged so as to elastically abut against the other guide body 76 by the spring 77. The onion 2 is reliably conveyed from 20 to the stem cutting part 40.
In this case, the left and right guide bodies 76 on the front side are biased by the pair of front and rear springs 77 so that the left and right transport belts 5 elastically contact each other, but the rear spring 77A is biased by the front spring 77B. Since the pressing force of the guide body 56 of the guiding portion 55 increases the holding force of the rear portion of the guide body 76 that acts on the stem of the onion 2, the stem before being cut by the stem cutting portion 40 is set. Can be prevented, and this can be prevented, and since the holding force of the conveying belt 5 is increased at the front portion of the guide body 76, it is cut by the stem cutting portion 40. Can prevent stalks from falling.

  Thus, the support legs 3 that support the body frame 1 are configured by providing a pair of left and right leg portions 80 at the front and rear, and the front side support legs 3A and the rear side support legs 3B are respectively rotatable so as to be rotatable. Since the front support leg 3A and the rear support leg 3B that are folded are parallel to each other in a side view, the outer shape of the bulb vegetable preparation machine is large. Therefore, it is possible to further reduce the size of the square, and to facilitate transportation and storage of the bulb vegetable preparation machine.

  The front support leg 3A is provided with a stay 81 at the upper part of the leg portion 80, and the stay 81 protrudes rearward in a side view with respect to the standing center line of the leg portion 80 to form a protrusion portion 82. It is attached to the left and right frames 45 of the fuselage frame 1 by means of a pivot fulcrum attachment shaft 83, and the rear support leg 3B projects a stay 81 provided on the upper part of the leg part 80 to the front side in a side view with respect to the standing center line of the leg part 80.
