[Detailed Description of the Invention] (Field of Industrial Application) This invention is an improvement in a chestnut picking machine that peels chestnuts, especially cut chestnuts obtained by cutting steamed chestnuts, and crushes the pulp to take in only the fruit. Regarding.

(Prior technology) A chestnut picking machine includes a feeding container into which cut chestnuts cut into skins are fed into, and a pair of rotating rollers placed close to each other directly below the container and having many small holes formed in the roller surface of the feeding container. Some are equipped with rollers. With this configuration, the chestnuts in the container are sent between the rotating rollers, and the peel and astringent skin of the chestnuts are peeled off by the frictional pressure of the rollers, the pulp is crushed, and only the fruit is taken in through the small holes. .

(Problems to be solved by the invention) However, in the case of the chestnut picking machine mentioned above,
The cut chestnuts in the charging container tend to roll and play on the roller surface, and cannot necessarily be fed smoothly between the rotating rollers. Therefore, as time passes, the chestnuts in the container overflow, and it is no longer possible to add new chestnuts, leading to a phenomenon in which the efficiency of peeling and harvesting chestnuts suddenly decreases.

In view of the above-mentioned problems of the conventional art, the present invention provides a chestnut fruiting machine that can efficiently peel and fruit chestnuts by smoothly and reliably feeding the chestnuts fed to the rotating roller side. With the goal.

(Means for Solving the Problems) In order to achieve the above object, the present invention has the following configuration. That is, the chestnut picking machine according to the present invention has an input container into which cut chestnuts are input, and a large number of small holes on the roller surface, and peels the chestnuts sent from the container and crushes the pulp. and a pair of rotating rollers that take in only the fruit through the small hole. The chestnuts in the container are forcibly sent out between the rollers by a pushing tool that repeatedly moves in and out of the container.

(Example) Hereinafter, an example in which the present invention is embodied in a chestnut picking machine having a chestnut cutting mechanism will be described based on the drawings.

In the figure, 1 shows the entire chestnut picking machine, which includes a chestnut cutting mechanism that cuts steamed chestnuts in half along with the skin, and a fruiting mechanism that peels the cut chestnuts and removes the fruit. It consists of. Both of these mechanical parts use a motor M housed in the drive part 2 as a drive source, and use the output shaft S of the reducer D as a main shaft to obtain power through chain transmission.

First, to explain the chestnut cutting mechanism section, the mechanism section is provided on the right side of the main body of the fruit picking machine 1, and includes a rotary body 3 that receives and feeds the steamed chestnuts one by one, and a rotary body 3 that receives and feeds the steamed chestnuts one by one. It is equipped with a rotary blade 4 for cutting chestnuts in half.

The rotating body 3 is composed of a pair of discs 3a, and has a large number of receiving openings 5 formed on its peripheral surface to receive chestnuts one by one. The receiving opening 5 has a rectangular opening with rounded corners, and has a tapered cross section that narrows at the bottom 6 to match the shape of the chestnut so that the received chestnuts do not play around in the mouth. The circumferential center of this receiving port 5, that is, the pair of disks 3a
A groove 7 is provided at the place where the two sides meet, deeper than the bottom 6 and formed vertically across each receiving port 5, and the rotary blade 4 is installed so that it can rotate into the groove 7. Deploy.

Immediately below this rotating body 3, a suitable container for collecting cut chestnuts is placed.

Note that 8 is a container that utilizes the inclined surface C at the upper front of the fruit picking machine 1, into which chestnuts to be cut are once placed. Further, numeral 9 is a closing lid that covers the side surface of the chestnut cutting mechanism, and is opened and closed by a hinge 10.

Next, the actual picking mechanism will be explained. The mechanical section is provided on the left side of the fruit picking machine 1, and includes a charging container 11 into which cut chestnuts are input, a pair of rotating rollers 12 which peel the chestnuts sent out from the container 11 and take in the nuts, and A sending device 13 for forcibly sending out the chestnuts in 11 between the rollers 12
Equipped with.

First, the charging container 11 has a mounting part 14 that is molded in one piece.
It is a hollow box-shaped container attached to the side of the grain picking machine 1 through the
In addition, a discharge port 16 is opened at the bottom of each of the two. Both sides of this delivery port 16 are openings cut out in an arc shape so that the rotating roller 12 can closely follow the delivery port 16, and on one side thereof, the delivery device, which will be described in detail later, is provided. 13
It has an entrance/exit 18 through which a pusher 17 enters and exits.

Next, a pair of rotating rollers 12 are arranged on both sides below the container 11 so as to be close to each other so as to sandwich the outlet 16 therebetween, and to rotate inwardly with respect to each other with a slight interval between them. This roller 12
is a rotating body having a U-shaped cross section with one side (the front side in the embodiment) open, and the roller surface 19 has a roller 12 for introducing peeled and crushed chestnuts into the roller 12 by frictional pressure. A large number of small holes 20 are formed all around the circumference.

However, as clearly shown in FIG. 6, this small hole 20 is enlarged by chamfering 21 at least the opening on the roller surface 19 side (both openings in the embodiment), so that the opening ends are vertically erected. Make sure there is no such thing. This is a measure to dull the sharpness of the small holes 20 so that the pericarp or astringent skin will not cut together with the fruit and enter the roller 12.

The rotating shaft 22 of one of the rollers 12 is supported by an eccentric bearing 23 shown by a dashed line in FIG. 25 are fixedly connected.
Therefore, by rotating the handle 24, the rotating shaft 22 is moved, which in turn moves one of the rollers 1.
2 can be freely moved toward and away from the other roller 12, so that the distance between the rollers 12 can be finely adjusted. This is because the thickness of the skin (including the astringent skin) differs depending on the type of chestnut, and the degree of separation of the pulp also differs, so by adjusting the distance between the rollers 12 each time, the friction pressure can be finely adjusted. This is because it is necessary to do so.

A delivery device 13 that interlocks with the rotation of the roller 12 is connected to this rotating shaft 22 via a link mechanism. That is, as shown clearly in FIG. 8, a collar 26 is attached to one end of the rotating shaft 22,
One end of the rod 28 is attached to the planting pin 27, and a plate 30 is connected to the other end by a pin 29. On the other hand, the sending device 13
consists of an arm 31 connected to a plate-shaped pushing tool 17 that is slightly curved so that its tip 17a faces the entrance/exit 18 of the container 11;
A proximal end portion of the plate 30 is connected through the plate 30.

Therefore, when the collar 26 rotates, the rod 28
The plate 30 connected to the plate 30 moves up and down as shown by arrow A in the figure, and the arm 31 and pusher 17 connected to this plate 30 move up and down as shown by arrow B in the figure in conjunction with the vertical movement. Perform a head-shaking exercise. Thus, the tip 17 of the pusher 17
a is the container 11 every time the roller 12 rotates once.
Move in and out once (see Figure 5) and repeat this process.

Next, in the lower central part of the pair of rollers 12,
A mounting base 33 is provided over which a gutter 32 for collecting chestnuts taken into the roller 12 is hung. The mounting base 33 is integrally molded with support bodies 34 arranged on the left and right sides, and the body 34 includes an inclined piece 34a that supports the gutter 32 at an angle of approximately 45 degrees with respect to the horizontal plane. In the vertical part of the main body 34, a contact plate 35 is provided, which makes the cutting edge of the tip lightly contact the roller surface 19, and peels off the chestnut skin and astringent skin that are stuck to the roller surface 19, and prevents them from being mixed with the fruit. to fix. However, the cutting edge of this contact plate 35 wears out due to contact with the roller surface 19.
Therefore, when the cutting edge is worn out, the same contact plate 35
The mounting hole is a long hole 36 so that the roller can be moved in the direction of the roller 12.

A guard 37 that covers the entire mechanism is removably attached to the picking mechanism having such a structure to ensure safety. As shown by the dashed line in FIG. 3, the guard 37 includes a skirt portion 38 that covers the fruit picking mechanism, and a case portion 39 on the upper portion of which accommodates the chestnuts cut by the chestnut cutting mechanism. This case part 39 has a container 11
An input opening 40 communicating with the reception opening 15 is opened to allow cutting chestnuts to be input.

Reference numeral 41 denotes a horizontal stand attached to the lower side of the fruit harvesting machine 1, on which is placed a container 42 for collecting the skins and astringent skins of chestnuts that have been peeled and fallen. A guide plate 44 with a support rod 43 for preventing the problem is provided. Note that, for example, an angled stopper metal fitting is fixed to the bottom of the gutter 32, and this metal fitting is hung on the upper end of the guide plate 44 to prevent the gutter 32 from slipping down.

45 is a leg wheel attached to the bottom of the grain picking machine 1, 46
is a switch that turns the drive of Aircraft 1 on and off.

Next, regarding the drive mechanism of this grain picking machine 1, the seventh
To explain briefly based on the drawing, a sprocket wheel 47 is attached to the output shaft S of the reducer D, and a chain 48 is attached. As shown in the figure, this chain 48 is connected to sprocket wheels 50 and 51 which are pivotally attached to the respective rotating shafts 22 of the pair of rotating rollers 12, with a sprocket wheel 49 on which the rotary blade 4 is coaxially mounted sandwiched between the chains 48 and 49. pass it over. Therefore, the rotating rollers 12 rotate inwardly as shown by arrows C and D in the figure, respectively.
Frictional pressure can be applied to the chestnuts being thrown. Further, the rotary blade 4 rotates clockwise as shown by arrow E in the figure.

Then, another sprocket wheel 52 is coaxially attached to the wheel 51, and this wheel 52
and a sprocket wheel 53 to which the rotating body 3 is coaxially attached. Therefore, the rotary body 3 rotates counterclockwise as shown by arrow F in the figure, and can feed the chestnuts one by one to the rotary blade 4, which rotates clockwise.

Note that, as already detailed, one roller 12
A delivery device 13 is connected to the rotating shaft 22 via a link mechanism. Therefore, the pushing tool 17 of the device 13 swings in conjunction with the rotation of the roller 12, and pushes the chestnuts in the container 11 into the roller 1.
It can be sent between 2 rooms.

In order to peel the chestnuts and extract the nuts using the fruit picking machine constructed as described above, the chestnuts are first put into the container 8 provided at the upper front of the fruit picking machine 1. The chestnuts are then put into the receiving port 5 of the rotary body 3 one by one and fed into the rotary blade 4. The fed chestnuts are cut in half along with the skin by the rotating blade 4, and the cut chestnuts fall naturally as the rotating body 3 rotates, and are placed in a suitable container placed directly below. It will be collected.

The collected cut chestnuts are stored in the case part 39 of the guard 37.
At the same time, it is put into the container 11 through the inlet 40. The placed chestnuts are forcibly sent out between the rollers 12 by a pushing tool 17 that repeatedly enters and exits the container 11. roller 12
The chestnuts sent out in the meantime have their pericarp and astringent skin peeled off by the frictional pressure of the same roller 12, and
The pulp is also crushed and only the fruit is taken into the roller 12 through the small holes 20. The chestnuts taken into the roller 12 are directly transferred to the gutter 3.
2 to be sent out and collected.

On the other hand, the peeled chestnut skin and astringent skin are separated from the fruit, are sent downward by the rollers 12 and fall, and are collected by a container 42 placed directly below.

In this embodiment, the drive of the delivery device 13 is linked to the rotation of the roller 12, but it is not necessarily necessary to do so; the device 13 is driven independently, and the speed of the swinging motion and the rotation of the It may be configured such that the swing range etc. can be adjusted arbitrarily. Further, the chestnut cutting mechanism may be separate and independent, and the chestnut cutting machine may include only the kernel picking mechanism. In addition, various design changes are possible without departing from the gist of the present invention, such as changing the shapes of the charging container 11, the pushing tool 17, etc. as appropriate.

(Effects of the Invention) As is clear from the detailed description above, the chestnut picking machine of the present invention has a pushing device that repeatedly moves chestnuts into and out of the container, which conventionally would play around in the container. The material is forcibly sent between the rotating rollers. Therefore, the chestnuts placed into the container can be smoothly sent out one after another to the roller side, and the problem of the chestnuts overflowing from the container, which was the case with conventional machines, is reliably eliminated, and the peeling of the chestnuts is prevented. And the work efficiency of harvesting will be improved all at once.
