[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary roll for separating and podging immature and soft peanut pods from a grass body without damaging the pods.

[0002]

2. Description of the Related Art Most of the conventional so-called dehulling machines or threshing machines are devices for recovering grains from a fully-ripened dried pod (for example, Japanese Utility Model Publication No. 39-33698, Japanese Utility Model Publication No. 2-5553).
4), it is not appropriate to separate the pods from the peanut grass by this type of device. That is, the peanut pod, unlike ordinary beans, bears fruit at the tip of the stalk that hangs from the stem to the ground, and the strength of the stalk itself is considerably strong. Therefore, in order to remove pods from peanuts, it is necessary to separate the pod from the stalk and to separate the pod-bearing handle from the stem. As a device for decapsulation of raw peanuts, there has been proposed Kaikaihei 3-61832, but this device inserts a peanut grass body between a pair of upper and lower rotating brushes and moves it in the rotation axis direction to decapsulate. Since the mechanism is complicated and the stem and leaves and the stalk are entangled between the brushes to reduce the pod shattering effect, it is necessary to remove them. Furthermore, when obtaining peanut pods for boiled beans, it is necessary to remove the pods in an immature state, and thus the pod surface is easily damaged during the pod removal.

[0003]

[Problems to be solved] According to the present invention, the device is made as small and lightweight as possible so that the pods can be podded in the field, and the immature pods can be effectively podded without scratching and can be safely operated. It provides a roll for pod shattering.

[0004]

SOLUTION: The pod roll of the present invention is fixed to a movable machine frame, and is attached to the surface of a pod-rotating drum that is axially attached to a rotary shaft that penetrates a pod chamber whose upper surface is open. A row of blades formed by arranging a plurality of rectangular or semicircular blades made of an elastic material having a constant width along the axial direction with a space interval of substantially the same width as the width of the blades. Are provided symmetrically at regular intervals in the circumferential direction of the rotary cylinder, and are provided so as to be engaged with each other so that the blade plates in the adjacent blade plate rows do not face each other.

In the roll of the present invention, rubber or soft plastic is preferable as the blade material, and the height of the blade is preferably 22 to 30 mm depending on the type of peanut, and the thickness of the blade is made of rubber. 3-5 mm is suitable. Thus, the blade plate can be bent with a force of about several 100 g. The shape of the vane plate is preferably a square shape or a corrugated shape whose upper part has an arc surface. Further, the means for attaching the vane plate is optional, but the vane plate may be integrally formed with the rotary drum so that the vane plate can be bent from the root. Furthermore, the width of the blade is 20
~ 30 mm, the spacing between each row of blades on the circumferential surface is 40-50
mm is preferred. The inner surface of the decapsulating chamber is further adhered with rubber or an equivalent soft elastic material to further reduce damage to the surface of the pod.

In the apparatus provided with the roll of the present invention, it is effective to provide an oscillating sieve inclined from the lower end of the front wall of the decapping chamber toward the lower side of the facing wall in order to separate the pods at the same time as the decapsulation. The sieve used is one in which metal wires are arranged at regular intervals in the vertical direction, and the swinging means is a crank rod connected to the drive source of the rotating cylinder through a speed reduction mechanism. Make a move.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 1 is a machine frame, 2 is a decapsulating chamber fixed to the machine frame and having an open upper surface, 3 is a front wall, 4 is a facing wall, 4A is an inclined wall connected to the facing wall, 5, 6 Is the side wall. 7 is body length 3
Rotating cylinder of 00 mm, diameter of about 60 mm, 8 is 4 mm thick,
It is a rectangular plate blade made of rubber having a width of 24 mm and a height of about 25 mm. In FIG. 3, 8L is a blade plate array, and the blade plates 8 are formed along the body axis with a gap 8a having a width (W = 24 mm) substantially the same as the width W thereof.
The vane plate row interval G on the circumference is 45 mm. Reference numeral 9 denotes a rotary shaft, which is mounted between the side walls and one of which is directly connected to an outdoor motor 10. The rotation speed is 1200 to 1600 r. p.
m. Is. Reference numeral 11 denotes an oscillating sieve for pod separation, which is a frame 1
2 is a mounting member 1 that supports metal wires 13 that are arranged in parallel in the vertical direction at regular intervals (12 mm), and that protrudes from the upper side portion 14 of the frame body.
5 is fixed to the swing shaft 16 at an angle of about 45 °. Reference numeral 30 is a dust receiving box placed immediately below the sieve, and 31 is a pod housing box. The swing shaft 16 penetrates a sliding bearing 17 fixed to a machine frame located at the lower end of the front wall and is pin-connected 18 to a crank rod 19. The position of the pin 20 of the rotary disk 21 was determined so that the stroke of the swing shaft was about 100 mm. Reference numeral 22 denotes a rotary shaft of a disc, which is connected to a speed reducer 23 of a motor. Reference numeral 24 is a stopper provided at the end of the swing shaft.

[0008]

When the motor 10 is driven, the rotary drum 7 rotates in the direction of the arrow, and the sieve 11 oscillates (oscillation cycle 80 minutes / minute).
Times). In this state, the operator presses the peanut grass body from the open upper surface of the decapsulating chamber against the rotating drum with the root facing forward. The grass with a pod is 2 by the elastic blade plate 8 facing in the rotation direction.
The pods are intermittently beaten over the entire width of the roll at a time interval corresponding to a double blade row interval 2G to separate the pod body from the handle or form a pod with a handle and drop it on the sieve surface. The width of the blades (or the space between the blades) and the distance between the rows of blades on the circumferential surface of the rotating drum are related to the pod removal efficiency. In the case of the variety Nacateko Taka, the width and the spacing are 24 mm and 45 mm, respectively. I got the best results. The dust other than the pods falls into the receiving box 30 directly below the swinging sieve, and the pods are guided from the lower end side of the sieve into the storage box 31 for separation.

[0009]

[Effect] The operator only presses the peanut grass from the upper part of the dehulling chamber against the rotating dehulling roll, and inserts the grass into the machine by hand as in the case of dehulling the peanut with a conventional thresher. Since it is not a method, there is no danger of the hands being pulled into the aircraft and it is safe. Moreover, in the proposed roll,
The peanut pods are put into the space between the elastic blades, and immediately after that they are squeezed by the blades that are squeezed and squeezed, which makes it easy to separate the handle from the pod, and efficient pod removal that cannot be expected with conventional equipment. You can Further, since the interval between the rotary vanes is relatively wide, the handle does not cling to each other and the work is not interrupted, so that the efficiency is improved. Further, the elastic blade used in the roll of the present invention has an effect that it does not damage the surface of the immature pod because it bends from its root, and, in combination with the above advantages, the removal of peanuts for boiled beans under hot summer in the midsummer. An excellent device can be provided for pod work. Further, the roll of the present invention has a simpler structure and is lighter than the decapsulating means of the conventional device, so that the entire device can be made smaller and lighter and can be installed and used at a harvest site.
