[0004] However, in both Patent Documents 1 and 2, rails must be laid in advance in the fields to be worked on, and installation takes time and effort. In particular, Patent Document 1 requires a traveling machine that travels across the rails and a slider that can move along the traveling machine, and the slider must be provided with a mounting body that can move up and down and rotate freely, resulting in a problem that the device configuration is complex and large-scale, and lacks flexibility in installation and ease of handling. In addition, Patent Document 2 has a problem that the vehicle body can only travel along the track, limiting the travel path and lacking in work (travel) efficiency. Furthermore, Patent Document 2 describes that the vehicle is equipped with agricultural machinery corresponding to various work purposes such as plowing, rice planting, weeding, rice harvesting and sowing, seed planting, harvesting, fertilization, and disinfection, but does not describe the specific structure (configuration) and operation of the agricultural machinery corresponding to each work. The present invention has been made in consideration of the above circumstances, and aims to provide a labor-saving agricultural work device that can reduce the workload of agricultural workers by moving around fields and harvesting (threshing) only the seeds or fruits of crops such as rice, wheat, and buckwheat without cutting the stalks.

The seed storage section and / or the chemical storage section may be used (shared) with the harvest storage section. Chemicals include fertilizers, agricultural chemicals, and pest control agents or repellents. The form of the chemicals may be powder (solid) or liquid, and they are discharged (dropped), dripped, scattered, or sprayed according to their respective forms.

[0011] In the agricultural work equipment of the present invention, the movement means of the movable body has three or more vertical rotation shafts rotatably attached to the main body of the movable body, wheels attached to the tip of each of the vertical rotation shafts, and a direction-changing drive unit connected to the base side of each of the vertical rotation shafts and rotating each of the vertical rotation shafts in 90-degree increments to change the direction of each of the wheels, and it is preferable that the movable body be able to switch between movement in the forward / backward direction and movement in the left / right direction without changing the direction of the main body. Effect of the Invention

[0012] The agricultural work device of the present invention can move through fields and scrape and collect only the seeds or fruits of crops from the stems without cutting the stems themselves, thereby reducing the number of work steps during harvesting and lightening the workload of workers, thereby making agricultural work more labor-saving and automated.

[0013] In the agricultural work apparatus of the present invention, when the harvesting means is equipped with a rotating body that is rotated and driven with a rotation axis arranged along a horizontal direction perpendicular to the direction of travel of the moving body, and one or more comb tooth portions are attached to the outer periphery of the rotating body, by simply rotating the rotating body while moving the moving body in a field, the one or more comb tooth portions that rotate together with the rotating body can efficiently scrape off only the seeds or fruits of the crop in a short period of time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Next, with reference to the attached drawings, an embodiment of the present invention will be described for understanding the present invention. An agricultural work apparatus 10 according to one embodiment of the present invention shown in FIG. 1 performs agricultural work while moving through fields. The agricultural work apparatus 10 has a movable body 13 equipped with a main body 11 and a moving means 12 attached to the main body 11, a harvesting means 14 detachably attached to the main body 11 of the movable body 13, and a harvest collection section 15 provided on the main body 11 of the movable body 13 for collecting seeds or fruits of the crop harvested by the harvesting means 14.

[0021] The moving means 12 has three or more (four in this example) vertical rotation shafts 16 rotatably attached to the main body 11 of the moving body 13, wheels 17 attached to the tip of each vertical rotation shaft 16, and a direction-changing drive unit (not shown) such as a motor connected to the base of each vertical rotation shaft 16 and rotating each vertical rotation shaft 16 in 90-degree increments to change the direction of each wheel 17. This allows only each wheel 17 to change direction on the spot, as shown in Fig. 6, and the moving body 13 can switch between forward / rearward movement and left / right movement without changing the direction of the main body 11.

[0022] As shown in Fig. 1 and Fig. 2 (A) and (B), the harvesting means 14 has a rotating shaft 19 arranged along a horizontal direction perpendicular to the moving direction of the moving body 13, and is equipped with a rotating body 20 that is rotated by a comb tooth drive unit (not shown) such as a motor, and a plurality of (here, eight) comb tooth parts 21 are attached radially to the outer periphery of the rotating body 20. As shown in Fig. 2 (A) and (B), the comb tooth part 21 has a plurality of teeth 22 arranged in parallel at a predetermined interval in a horizontal direction perpendicular to the moving direction of the moving body 13, and a gap 23 formed between each two adjacent teeth 22. By rotating the rotating body 19 by the comb tooth drive unit (rotating clockwise in Fig. 1), the comb tooth part 21 can be moved from the lower side to the upper side of the stalk of the crop. Then, by passing the stalk of the crop through the gap 23 of the comb tooth part 21, the seeds or fruits of the crop are scraped off from the stalk without the stalk being cut and collected in the harvest collection unit 15. The length, number and spacing of the teeth are appropriately selected, and the spacing of the teeth in the horizontal direction and the circumferential direction may be uniform (same intervals, equal intervals) or non-uniform (unequal intervals). The tooth shape may be circular or polygonal in cross section, and the cross section may be uniform over the entire length of the tooth, or may be tapered from the base side to the tip side.

[0023] The movable body 13 has a working means attachment section 25 attached to the main body section 11 so that it can move up and down. By attaching the harvesting means 14 to this working means attachment section 25, the position (height) of the harvesting means 14 can be optimally adjusted according to the height of the crop to be harvested (the length of the stem and the position (height) of the ear, etc.), and the seeds or fruits of the crop can be reliably collected without any leakage. The moving body 13 may also have a height adjustment means for moving the moving means 12 up and down relative to the main body 11. This allows the position (height) of the harvesting means 14 to be adjusted together with the main body 11, and the same actions and effects as described above can be obtained. As this height adjustment means, one that extends and retracts the vertical rotation shaft 16 of the moving means 12 is preferably used, but is not limited to this. Note that it is preferable for the moving body to have either one or both of a working means attachment section and a height adjustment means, but if the crop to be harvested is specified (the length of the stalk and the position (height) of the ear, etc. are limited) and there is no need to move the working means attachment section and the moving means up and down, both may be omitted.

[0024] In this embodiment, the harvest collecting unit 15 is provided in the main body 11 of the moving body 13, but may be connected (integrated) with the harvesting means 14. When the harvest collecting unit 15 is provided in the main body 11 of the moving body 13, it is preferable that the harvest collecting unit 15 also moves up and down in response to the up and down movement of the harvesting means 14. The up and down movement of the harvesting means 14 and the up and down movement of the harvest collecting unit 15 may be independent or linked, and the harvest collecting unit 15 may be attached to the working means attachment unit 25 and move up and down together with the harvesting means 14. The harvest collecting unit 15 may be fixed (integrated) to the main body 11 of the moving body 13, or may be detachably attached. In this embodiment, the harvesting means 14 is arranged in the center of the fore-and-aft direction of the main body 11 of the movable body 13, and the harvest collection section 15 is arranged on the rear side of the main body 11 of the movable body 13. However, if a harvest collection section having openings on the front and rear is arranged in the center of the fore-and-aft direction of the main body 11 of the movable body 13, and the harvesting means 14 is arranged on the front and rear sides of the main body 11 of the movable body 13 (in front of and behind the harvest collection section), the harvest can be collected regardless of the direction of travel of the movable body 13 (when moving forward or backward), improving work efficiency.

[0025] The agricultural work device 10 may have a crushing means 26 shown in Fig. 3 (A) and (B). The crushing means 26 has a vertical rotor 28 that rotates around a vertical shaft 27, and a plurality of crushing blades 29 arranged radially on the outer periphery of the vertical rotor 28 at a plurality of locations in the longitudinal direction. In this embodiment, four crushing blades 29 are arranged radially at equal angular intervals (90 degrees) at the same height (within the same plane) on the outer periphery of the vertical rotor 28, and are attached with a phase difference of 45 degrees in the circumferential direction (with the attachment positions shifted by 45 degrees) so that adjacent crushing blades 29 in the height direction (up and down) of the vertical rotor 28 do not overlap, but the shape, number and arrangement of the crushing blades 29 are not limited to this embodiment and may be selected as appropriate. This crushing means 26 can be detachably attached to the main body 11 of the movable body 13 in place of the harvesting means 14, thereby crushing the stalks of crops remaining in the fields. The number of crushing means 26 may be one or more, and their arrangement is selected appropriately, but by arranging multiple crushing means 26 side by side in the width direction of the main body 11 of the movable body 13, the stalks of crops can be crushed even finer.

[0026] A crushing means driving section (not shown), such as a motor that rotates the vertical rotor 28, may be integrated with the crushing means 26 while being connected to the vertical shaft 27 and attached to the main body 11 of the movable body 13, or may be built in the main body 11 of the movable body 13 in advance and connected to the vertical shaft 27 when the crushing means 26 is attached to the main body 11 of the movable body 13. The crushing means 26 may be directly attached to the main body 11 of the movable body 13, or may be attached to the main body 11 of the movable body 13 via the working means attachment section 25. The crop stalks crushed by the crushing means 26 may be dropped directly into the field and used as leaf mold, or may be collected by a crushed material recovery unit (not shown). The crushed material recovery unit may be attached to the main body 11 of the mobile body 13 so as to be replaceable with the harvested material recovery unit 15, or may be used as both the harvested material recovery unit 15 and the crushed material recovery unit.

[0027] As shown in Figures 4 to 6, the agricultural work apparatus 10 can have a cultivation means 31 for cultivating fields, which is detachably attached to a working means mounting section 25 provided on the main body 11 of the movable body 13 in place of the harvesting means 14. The configuration (structure) of the cultivation means 31 is similar to that of a conventionally known one, and a cultivation means having a plurality of hatchet tines (also called cultivation tines or rotary blades, etc.) 33 radially arranged on the outer periphery of a cultivation shaft 32 arranged parallel to the width direction of the main body 11 of the movable body 13 at a plurality of locations in the longitudinal direction is preferably used, but the shape, number and arrangement of the hatchet tines 33 are not limited to this embodiment and may be selected as appropriate.

[0028] With the above configuration, the agricultural work apparatus 10 can plow a field (crush and mix the soil of the field) by lowering and rotating the cultivating means 31 with the working means mounting part 25 and moving the moving body 13 back and forth as shown in FIG. 5. The rotation direction of the cultivating means 3 may be the same or opposite when the moving body 13 moves forward and backward, and the rotation direction may be appropriately reversed during the movement. As previously described with reference to FIG. 6, the agricultural work apparatus 10 can move left and right by rotating each vertical rotation shaft 16 90 degrees from the normal state (the state when moving forward and backward in FIG. 4 and FIG. 5) so that the direction of each wheel 17 of the moving body 12 is parallel to the width direction of the main body 11 of the moving body 13. At this time, by raising the cultivating means 31 with the working means mounting part 25 as shown in FIG. 6, the cultivating means 31 (machete claw 33) does not come into contact with the soil (ground) and the like, and the moving body 13 can be moved smoothly. During left-right movement, it is preferable to stop the rotation of the cultivating means 31, but the cultivating means 31 may be left rotating for a short period of time.

[0029] The mobile body of the agricultural work equipment may be one that moves autonomously or one that moves by remote control, and may be capable of switching (selecting) between autonomous movement and remote control movement. In an autonomously moving body, the movement route is stored in the main body, and the operation of each part, such as the moving means, harvesting means, and working means attachment part, corresponding to the movement route (e.g. control data such as the rotation speed, rotation time, stop time, and rotation direction of the motors that drive each part) is saved in chronological order, eliminating the need for operation by an operator. In a mobile body that moves by remote control, an operator can use an operating means to give instructions to the main body of the mobile body by wireless communication. Then, the main body receives instructions (operation signals) from the operating means and gives instructions (operation signals) to the moving means, harvesting means, and working means mounting unit, etc., so that each unit performs a predetermined (instructed) operation. The operating means may be of a manual operation type in which an operator (operator) gives instructions (sends operation signals) to the main body of the mobile body by manually operating a lever, handle, joystick, etc., or of an automatic operation type in which an operation program for operating each unit while moving the mobile body along a preset moving path is stored and instructions are given to the main body of the mobile body according to the operation program. In the manual operation type, a camera is mounted on the main body of the mobile body, so that the operator can operate (give instructions) while checking the image captured by the camera on a monitor at hand.

[0030] Next, a modified harvesting means 14A will be described with reference to Figures 7(A) and (B). Note that the same components as those of the harvesting means 14 will be given the same reference numerals and the description thereof will be omitted. The harvesting means 14A is detachably attached to the main body 11 (working means mounting section 25) of the moving body 13, similar to the harvesting means 14 (see FIG. 1). The harvesting means 14A includes a driving wheel 36 having a horizontal driving shaft 35 arranged perpendicular to the traveling direction (arrow a) of the moving body 13 and rotated by a comb tooth driving section (not shown), a driven wheel 38 having a horizontal driven shaft 37 parallel to the horizontal driving shaft 35 and arranged parallel to the driving wheel 36 at a distance, and an endless track 39 wound between the driving wheel 36 and the driven wheel 38, and a plurality of (here, four) comb tooth sections 21 are attached to the outer periphery of the endless track 39. By rotating the drive wheel 36 together with the horizontal drive shaft 35 by a comb tooth drive unit such as a motor connected to the horizontal drive shaft 35, the driven wheel 38 rotates together with the horizontal driven shaft 37, and the endless track 39 rotates and moves between the drive wheel 36 and the driven wheel 38. Then, the multiple comb tooth units 21 move together with the endless track 39, so that only the seeds or fruits of the crop are scraped off and harvested. In this embodiment, as shown in FIG. 7(A), when the moving body 13 advances in the direction of the arrow a, the comb tooth units 21 move obliquely upward from a rear low position to a front high position of the moving body 13 as shown by the arrow b with respect to the crop (not shown) located in front of the moving body 13, so that the comb tooth units 21 can move from the lower side to the upper side of the stalk of the crop. Then, by passing the stalk of the crop through the gap 23 of the comb tooth units 21, the seeds or fruits of the crop are scraped off from the stalk without the stalk being cut. In this embodiment, the angle between the horizontal plane and the moving direction (arrow b) of the comb teeth portion 21 is set to 45 degrees, but it is not limited to this and may be appropriately selected. Also, the horizontal drive shaft 35 and drive wheel 36 and the horizontal driven shaft 37 and driven wheel 38 may be interchanged.

[0031] Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations described in the above embodiments, and also includes other embodiments and variations that can be considered within the scope of the matters described in the claims. The mobile unit is preferably driven by a battery built into the main body, but is not limited to this. The battery may be charged by a commercial power source or by electricity generated by a solar panel attached to the main body. In the above embodiment, the agricultural work equipment (mobile body) is used to collect harvested crops, crush crop stalks after harvest, and till fields. However, instead of these means, the agricultural work equipment can also sow seeds in fields using a seed sowing means that is detachably attached to the main body of the mobile body, and can supply chemicals to fields using a chemical application means. In the above embodiment, the harvesting means is described as one in which a rotor with a plurality of comb teeth attached to its outer periphery is rotated by a comb teeth drive unit such as a motor, and one in which an endless track with a plurality of comb teeth attached to its outer periphery is wound between a drive wheel and a driven wheel and the drive wheel is rotated by a comb teeth drive unit such as a motor, but the harvesting means only needs to be able to scrape the seeds or fruits of the crop from the stem by passing the stem through the gaps in the comb teeth, and the structure and operation of the harvesting means are appropriately selected. For example, the structure may be such that the comb teeth are fixed to the main body, and the stem of the crop passes through the gaps in the comb teeth as the moving body moves, and the seeds or fruits are scraped off from the stem, or the structure may be such that the comb teeth vibrate (reciprocate) in the vertical or horizontal directions relative to the main body while the moving body is moving, and the seeds or fruits are scraped off from the stem of the crop that passes through the gaps in the comb teeth.
