[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device that pulls out carrots from fields and cuts leaves when they are determined.

[0002]

[Prior art]

 A device for digging up soil to extract root vegetables such as carrots is described in Japanese Utility Model Publication No. 1-44012 and Japanese Utility Model Publication No. 64-56619. The devices described in these publications are towed by a tractor to plow soil and carrots together for harvesting. Carrots dug up in plows are sorted and harvested from the soil. The harvested carrot is supplied to, for example, a cutting device described in Japanese Utility Model Publication No. 64-2638 to cut the leaves of the carrot from a predetermined position.

Using such a harvesting device and a cutting device, carrots can be mechanically pulled out to cut leaves. However, the device for harvesting carrots by dug up the soil with a plow cannot harvest the carrots very efficiently compared to the method of pulling out the carrots by hand. This is because the work of selecting and extracting carrots from the dug up soil is troublesome, and this work is not so different from the work of directly extracting the carrots. For this reason, the device of that structure cannot be expected to save labor in harvesting work and make farming work easier. In addition, the use of plows may damage carrots when digging up the soil, resulting in a significant decrease in commercial value. Furthermore, harvesting using plows has the disadvantage that it takes a lot of time to remove many thin hair roots that grow on the surface of carrots. It is because the carrots are dug up with the soil and the hair roots on the surface of the carrots cannot be cut during harvesting. Harvested carrots are shipped after removing the hair roots on the surface. In this way, plows are rarely used because they cannot harvest ginseng in a favorable condition and are heavy and heavy labor. Therefore, even though it takes a lot of time and effort, carrots are almost always used to grab the leaves by hand and pull out each one by hand to harvest. A device that can harvest carrots in a favorable condition has been earnestly desired in order to save labor and eliminate labor shortages.

In order to solve this drawback, the inventor of the present invention has developed a carrot extracting device shown in the side view of FIG. 1 and the plan view of FIG. 2 (Japanese Patent Application No. 4-200504). The device shown in this figure is as follows. The device is a trolley 1 having traveling wheels 2 that move along the carrots planted in the fields, a carrot extracting means 3 attached to the trolley 1, and a power source 4 for driving the traveling wheels 2 and the extracting means 3. It has and. The extracting means 3 includes a pulling conveyor 5 that pulls up the leaves of carrot and pulls them out from the ground. The pull-out conveyor 5 has a pair of belt conveyors 6, and the sandwiching gap 6A of the belt conveyor 6 is adjusted to a spacing that allows carrot leaves to be sandwiched. The pull-out conveyor 5 is arranged so as to be inclined upward, and the belt conveyor 6 in the sandwiching gap 6A is transported in the ascending direction. The horizontal speed of the belt conveyor 6 arranged so as to be inclined is adjusted to be substantially equal to the traveling speed of the carriage 1. When the trolley | bogie 1 runs with the extraction conveyor 5 pinching the leaf of the ginseng, it is comprised so that the ginseng may be extracted in the vertical direction by the inclined extraction conveyor 5. A cutter 7 is arranged on the lower surface of the extraction conveyor 5 in order to cut the extracted ginseng leaves with a predetermined plate. In this device, a carrot leaf that is pulled out by the pulling conveyor 5 and transferred by the pulling conveyor can be cut by the cutter 7.

The carrot extractor of this structure harvests carrots as follows. When the carrot extractor advances, the carrot leaves are guided into the sandwiching gap 6A of the pulling conveyor 5. The carrot leaf is sandwiched in the sandwiching gap 6A of the pulling conveyor 5. The carrots with the leaves sandwiched between them rise up along the inclined surface by the upward pulling conveyor 5. The moving speed of the pulling conveyor 5 in the horizontal direction is adjusted to be substantially equal to the moving speed of the trolley 1, so that the ginseng rising along the pulling conveyor 5 is pulled up vertically by the movement of the trolley 1, It is pulled out of the soil. A device having a cutter 7 below the pulling conveyor 5 cuts the ginseng leaves to be pulled up.

In this way, the device capable of pulling out carrots does not damage the carrots and cuts the hair roots on the surface when pulling out, similar to grasping leaves by hand. In addition, it has the feature that root vegetables can be harvested in an ideal state without breaking. In addition, by running the cart along the ridge, carrots can be harvested and leaves can be cut very efficiently. Therefore, this device has the feature that it is easier than the method of harvesting carrots manually and it is labor-saving and efficient in harvesting and cutting the leaves.

[0007]

[Problems to be solved by the device]

 However, the device of this structure has a drawback that the extracted ginseng leaves cannot be cut accurately at a predetermined position. The reason is that the pulling conveyor cannot pinch the leaves of carrot in the same position. In addition, the device of this structure has a drawback that the carrot leaves that are transferred to the ascending slope are cut by a cutter, so that the leaves cannot be cut horizontally accurately and the leaves are cut to some extent. A device with this structure can harvest carrots efficiently, and is ideal if the leaves can be cut accurately.

This device was developed to achieve this, and the important purpose of this device is to efficiently harvest carrots and also to remove the carrots that can be cut at the correct position to remove the leaves. It is to provide a device for cutting.

[0009]

[Means for Solving the Problems]

 The device for extracting ginseng and cutting leaves according to the present invention has the following structure in order to achieve the above-mentioned object. The device for extracting carrots and cutting the leaves has pulling conveyors 5 that are arranged parallel to each other so as to sandwich and remove the carrot leaves. The extraction conveyor 5 is arranged so as to incline upward in order to raise the carrots extracted from the ground. A cutting means 18 for cutting leaves is provided near the lower surface of the pulling conveyor 5.

Further, in the device for extracting carrots and cutting leaves of the present invention, the cutting means 18 is provided with a horizontal transfer conveyor 18 B located on the lower surface of the extraction conveyor 5. The horizontal transfer conveyor 18B has a slit 19 through which the leaves of carrot transferred by the pulling conveyor 5 can pass, and one end of the slit 19 is close to the lower surface of the pulling conveyor 5 and is horizontally or almost horizontally arranged. Further, a cutter 18A is arranged in the ginseng transfer path of the horizontal transfer conveyor 18B. Carrot leaves transferred by the horizontal transfer conveyor 18B and the extraction conveyor 5 are cut by the cutter 18A.

[0011]

[Action]

 The device for extracting ginseng and cutting leaves of the present invention harvests ginseng and cuts leaves as follows. The pull-out conveyor 5 pulls out the leaves of carrots from the ground and transfers them uphill. The carrots that are transferred uphill by the drawing conveyor 5 are transferred from the drawing conveyor 5 along the horizontal transfer conveyor 18B of the cutting means 18. Since the horizontal transfer conveyor 18B is horizontal and inclined to the upward slope of the pulling conveyor 5, the distance between the horizontal transfer conveyor 18B and the pulling conveyor 5 becomes wider as the carrots are transferred by the horizontal transfer conveyor 18B. Therefore, as the carrots are transferred, the leaves of the carrots are pulled up and come into contact with the lower surface of the horizontal transfer conveyor 18B to be transferred. The carrot transferred with its upper end abutting on the lower surface of the horizontal transfer conveyor 18B is cut with the cutter 18A at the predetermined position. The carrots whose leaves have been cut are dropped and discharged.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. However, the embodiments described below exemplify a device for embodying the technical idea of the present invention, and the device does not specify the device for extracting carrots and cutting leaves as follows.

Further, in this specification, in order to make it easier to understand the scope of the utility model registration claim, the numbers corresponding to the members shown in the embodiment are referred to as “utility model registration claim section” and “function section”. , And "members for solving the problems" are added. However, the members indicated in the claims for utility model registration are not specified as the members of the embodiment.

A device for extracting carrots and cutting leaves as shown in FIG. 3 cuts a car 1 having traveling wheels 2, carrot extracting means 3 attached to the car 1, and carrot leaves that have been pulled out. The cutting means 18, the traveling wheels 2, the extracting means 3, and the power source 4 for driving the cutting means 18 are provided.

The dolly 1 has traveling wheels 2 on both sides and has front driven wheels 8. Further, the carriage 1 is equipped with an engine as a power source 4 for driving the traveling wheels 2, the extracting means 3 and the cutting means 18. The engine has a built-in clutch. The output shaft of the clutch is connected to the traveling wheel 2, the extracting means 3 and the disconnecting means 18 via a chain. Although not shown, the lever for operating the engine throttle is connected to the handle 9 via a wire.

The extracting means 3 is shown in a side view of FIG. 3 and a plan view of FIG. The extraction means 3 shown in this figure comprises two sets of extraction conveyors 5 and a support plate 17 for extracting the leaves of carrots from the ground. Each pulling conveyor 5 has a pair of belt conveyors 6. The belt conveyor 6 adjusts the interval of the sandwiching gap 6A so that the leaves of the ginseng can be sandwiched, for example, in the range of 5 mm to 20 mm, in order to sandwich and pull out the leaves of the carrot.

The pull-out conveyor 5 is arranged so as to be inclined upward, and the belt conveyor 6 in the sandwiching gap 6A is transported in the upward direction. As the conveyor belt of the pulling conveyor 5, a rubber belt is used so that the carrot leaves can be sandwiched without slipping. However, you can also use a chain with a non-slip surface. The conveyor belt is in the shape of an endless belt, and both ends thereof are hung on the pulley 11. The pull-out conveyor 5 shown in the figure has an upper pulley 11 connected to an output shaft of an engine via a chain 10 and a sprocket 12. The conveyor belt is provided with a pressing member 13 on the back surface in order to pinch the carrot leaves in the pinching gap 6A to such an extent that the carrot leaf can be pulled out. The pressing member 13 presses the conveyor belt from the back side to increase the force with which the conveyor belt 6 holds the leaves of the carrot.

The force with which the conveyor belt holds the carrot leaves may be too strong or too weak. An apparatus for arranging the cutting means 18 below the pulling conveyor 5 to cut the leaves damages the carrots if the pulling conveyor 5 has too strong a force to pinch the leaves. In this device, the leaves do not slip in the sandwiching gap 6A when the carrot is pulled out from the soil, and the leaves need to slip to some extent in the sandwiching gap 6A when cutting the leaves. This is because when cutting leaves, carrots are transferred along the horizontal transfer conveyor 18B.

The support plate 17 guides the planted carrot to the sandwiching gap 6 A of the pulling conveyor 5. Therefore, the support plate 17 has a tapered shape with its tip being gradually narrowed. The extraction means 3 shown in FIG. 4 is provided with three support plates 17, and the space between the support plates 17 is positioned in the sandwiching gap 6A of the extraction conveyor 5. The spacing between the adjacent support plates 17 is designed to be wider than the spacing between the sandwiching gaps 6A. This is because the carrot leaves sandwiched between the sandwiching gaps 6A of the pulling conveyor 5 can be transferred smoothly. In the extraction step 3 shown in FIG. 4, the support plate 17 is arranged below the extraction conveyor 5. Although not shown, the support plate may be arranged above the drawing conveyor or above and below the drawing conveyor.

As shown in FIGS. 5 and 6, the cutting means 18 arranged below the drawing conveyor 5 has a horizontal transfer conveyor 18B and a cutter 18A.

The horizontal transfer conveyor 18B transfers the ginseng transferred uphill by the drawing conveyor 5 to the horizontal plane. The carrots transferred by the horizontal transfer conveyor 18B are transferred with the leaves sandwiched between the extraction conveyors 5. That is, the ginseng transferred by the horizontal transfer conveyor 18B and the pulling conveyor 5 horizontally transfers the carrot by the horizontal transfer conveyor 18B, and the leaves are pinched by the pulling conveyor 5 and transferred. As the carrots are transferred by the horizontal transfer conveyor 18B, the distance between the horizontal transfer conveyor 18B and the extraction conveyor 5 becomes wider. Therefore, the carrot transferred by the horizontal transfer conveyor 18B and the pulling conveyor 5 is transferred with the upper end of the carrot abutting the lower surface of the horizontal transfer conveyor 18B while the leaves slightly slipping up and down.

The horizontal transfer conveyor 18B transfers carrots that are pulled out by the pulling conveyor 5 and are transferred in an upward slope. Therefore, as shown in FIG. 5, one end of the horizontal transfer conveyor 18B is arranged horizontally or almost horizontally, close to the lower surface of the pulling conveyor 5. The horizontal transfer conveyor 18B transfers the carrots by passing the leaves of the carrots between them. Therefore, as shown in FIG. 6, the horizontal transfer conveyors 18B are disposed on both sides of the conveyor belt of the pulling conveyor 5 so that the ginseng leaves transferred by the pulling conveyor 5 can pass through the slits 19 and the carrot cannot pass through. Is provided.

The horizontal transfer conveyors 18 B arranged on both sides of the drawing conveyor 5 have rollers 20 on both sides. In FIGS. 5 and 6, the roller 20 arranged on the left side is divided into two. This is because the ginseng leaves are guided between the horizontal transfer conveyors 18B. One roller 20 on the right side in the figure drives this roller to drive the horizontal transfer conveyor 18B. Therefore, the rotary shaft 21 of the roller 20 on the right side is connected to the engine via the worm gear 22, the pulley 11 and the belt.

The horizontal transfer conveyor 18B shown in FIG. 5 is located above the lower conveyor belt and has a guide plate 23 extending horizontally. The guide plate 23 horizontally extends the conveyor belt to horizontally guide the carrots to be transferred.

The pulling conveyor 5 is designed to pull out the carrots sandwiched in the sandwiching gap 6A in the vertical direction when the carriage 1 moves forward. If carrot leaves are sandwiched between the pulling conveyors 5 without moving the cart 1, the carrots are pulled obliquely by the inclined pulling conveyors 5. If you pull the leaves in this direction, you will not be able to extract ginseng from the soil smoothly. In the device of the present invention, in order to pull out the carrot vertically, the trolley 1 is run in accordance with the horizontal movement of the pulling conveyor 5.

In FIG. 3, when the moving speed of the drawing conveyor 5 is V, the moving speed Vh of the drawing conveyor 5 in the horizontal direction is Vh = V / cos θ. However, θ is an angle formed by the pulling conveyor 5 with the horizontal plane. When the speed at which the carriage 1 moves forward is set equal to the horizontal speed Vh of the pulling conveyor 5, the carrots pulled by the pulling conveyor 5 are pulled vertically and pulled out from the soil. Therefore, the forward speed of the carriage 1 is adjusted to the horizontal speed Vh of the pulling conveyor 5. For example, in a device in which the angle θ formed by the pulling conveyor 5 with respect to the horizontal plane is 40 degrees, the forward speed of the carriage 1 is 0. Designed to be 766 (cos 40). Ideally, the forward speed of the carriage 1 is accurately adjusted to the speed Vh of the pulling conveyor 5 in the horizontal direction. However, carrots can be pulled out smoothly even if the forward speed of the trolley 1 deviates slightly from Vh. Therefore, the forward speed of the carriage 1 is set to be substantially equal to the horizontal speed Vh of the pulling conveyor 5. In this specification, the speed at which the forward speed of the carriage 1 is substantially equal to the horizontal speed Vh of the pulling conveyor 5 is preferably in the range of Vh ± 0.7Vh, more preferably in the range of Vh ± 0.5Vh. Shall mean.

The forward speed of the trolley 1 with respect to the pulling conveyor 5 is determined by the number of teeth of the sprocket 12 of the output shaft of the engine, the sprocket 12 of the traveling wheel 2, and the sprocket 12 fixed to the pulley 11 that drives the pulling conveyor 5. Can be adjusted.

[0028]

EFFECTS OF THE INVENTION The device for extracting carrots and cutting leaves of the present invention has a feature that the carrot leaves extracted by the extraction conveyor can be accurately cut at a predetermined position. This is because the upper end of the ginseng transferred to the ascending slope is brought into contact with and positioned on the lower surface of the plucking conveyor, and the leaves are cut in this state. When the leaves are sandwiched between the pulling conveyors and transported, and the carrots are transported horizontally by the horizontal transport conveyor, all the ginseng that was transported while being sandwiched by being slightly misaligned above and below the extraction conveyors The upper and lower parts are adjusted by abutting on the lower surface. Since the pull-out conveyor moves the leaves in the direction of the horizontal transfer conveyor while raising the leaves, carrots that are hung in the pull-down conveyor in a slightly lower position are also pulled up to the position where they abut the lower surface of the horizontal transfer conveyor. This is because the cutter is cut in this state. Therefore, the device for extracting carrots and cutting leaves of the present invention has a feature that the carrots extracted from the ground by the extraction conveyor can be efficiently and accurately cut.
