Description

  The present invention digs out crops such as potatoes, garlic, carrots, onions, straws, etc. from the soil, puts them on the field topsoil, naturally drys the crop skin and the soil attached to the skin, and then removes these from the field topsoil. Picking up crops or digging them out of the soil in the field and lifting them up with a conveyor, and dropping or manually removing non-crop crops such as clumps, stones, plant stems and leaves that are lifted together with the crops by hand The present invention relates to a device that automatically collects only the crops to be collected in a collection container, or a device that can manually sort out and classify crops that are picked up in the middle of a conveyor and that have non-standard quality.

  Currently, potato crops excavated from the soil in the field are placed on the field topsoil for a while, and after the skin and the soil attached to the skin are dried, the crops are harvested with a crop picker. This crop pick-up machine lifts the crops on the field topsoil with a pick-up conveyor diagonally installed at the front of the traveling aircraft, and the lifted crops extend rearward in the left-right direction and laterally feed using a net conveyor Transferred to the conveyor. The transferred crops are mixed with non-crop crops such as soil, stones, stems and leaves. Among them, small crops are dropped and removed during the transportation of the net conveyor of the transverse conveyor. On the other hand, large non-agricultural crops are removed manually, and the crops fall from the end of the cross feed conveyor and are stored in a collection container. This technique is known as Japanese Patent Application Laid-Open No. 2004-254582.

  The length of the horizontal conveyor of the conventional crop picking machine is about the distance between the fields. When the traveling speed of the crop pick-up machine is increased to increase the pick-up work speed, the number of crops picked up per unit time increases, and the transport speed of the pick-up conveyor and the lateral feed conveyor must be increased. When the conveyor speed was increased, the operator's sorting operation had to be made faster, and the burden on the worker's sorting operation was increased. To solve this problem, it is possible to increase the length of the transverse conveyor in the left-right direction. However, the transport distance (passing time) becomes longer and the work becomes easier, but it is carried on a truck etc. to transport the crop pick-up machine. When doing so, it could not be transported with the left and right overhangs, or even if it could, it became an obstacle during transport and it was difficult to transport safely. Further, when the vehicle travels on the road by itself, the transverse feed conveyor extending in the left-right direction becomes an obstacle to traffic. In order to solve this problem, it is conceivable to make the transverse conveyor foldable, but there is a problem that the folding structure becomes complicated and the production cost of the agricultural machine increases. Even if the number of workers is simply increased without increasing the lateral length of the transverse conveyor, the length of the horizontal conveyor does not change even if the number of processing per worker is reduced. Sorting and classification work was required. Therefore, the traveling speed on the field for harvesting by picking up a conventional crop picking machine was about 2 to 4 m per minute.

JP 2004-254582 A

  The problem to be solved by the present invention is to solve the conventional problems, and without causing the conveyor to be extended to the left and right, and without using a left and right folding structure, it can be run at a speed about twice as fast as the conventional one. It is also an object of the present invention to provide a high-capacity crop pick-up machine that can pick up, sort and classify the work without putting too much burden on the worker's sorting work.

The configuration of the present invention that solves this problem is as follows.
1) A pick-up device that is installed in the front of the airframe and picks up or digs out crops from the topsoil of the field and lifts them up to a predetermined height, and the crops and soil blocks that are lifted by the pick-up device. An endless conveyor with an open top that transports non-agricultural products such as stones and plant stems or leaves horizontally, so that workers can select between crops and non-agricultural products during transportation A crop picking machine provided with a sorting conveyor and a collection container for collecting crops sorted in the middle or at the end of the sorting conveyor,
The plane shape of the conveying path of the sorting conveyor has a generally square shape with arcs at the corners, and is structured to transfer crops and non-agricultural crops from the pick-up device into the path on the front side. The transportation path on one side and the rear side of the sorting conveyor is used as a sorting area by the operator, and a falling part is formed to drop the crops into the collection container by dropping the crop on the rear side or in the middle of the sorting conveyor. 2) A sorting conveyor is attached to the cable body at a predetermined pitch along the cable body and an endless cable body that is stretched horizontally in a substantially square shape that is rotated by a driving device. And a guide member extending in the feeding direction of an endless cord body that receives the tip of the receiving member from below and supports the receiving member horizontally except for the dropping portion. And place the collection container downward. Place the guide member at a low position so that the tip of the receiving member attached to the endless cord at the falling part is tilted downward or vertically from the horizontal, or drop it so that the crop on the receiving member is downward The crop pick-up machine described in 1), which is dropped and put into a collection container. 3) The receiving member is long enough to place the crop in the middle, and is formed into a single generally rectangular shape. The proximal end of the receiving member is attached at a predetermined pitch along the stretched endless cable body, and the distal end thereof is directed outward, and is received by a guide member provided outside the endless cable body except for the falling part. The crop picking machine described in 2) above, in which the end of the member is supported from below and kept horizontal. 4) Two endless cords stretched in a substantially square shape are provided on the same plane, and the drive device is installed inside and outside. A pair of endless cords are fed at the same speed, and the receiving members are inner and outer endless cords. It is attached so that the front ends of the receiving members face each other in close proximity to each other, and two guide members are provided inside and outside the front end portion of each receiving member. The receiving member is gradually lifted upward toward the corner so that the members do not overlap, and is shaped so that the height is returned horizontally after passing the corner, and the tip of the pair of opposing receiving members is lowered at the falling part. The crop picking machine 5) described above, wherein the guide member is lowered or eliminated so as to be inclined or vertical. 5) In the corner portion of the substantially square-shaped sorting conveyor, the crop receiving member is located below the guide member. A crop pick-up machine according to any one of 2), 3), 4) provided with a crop fall prevention body for preventing the fall from falling 6) Force feed blade for preventing the crop from rolling or slipping on the receiving member The provided crop pick-up machine according to any one of 2) to 5), provided with an excitation means for vibrating the guide member, and the guide member is vibrated to vibrate the receiving member so that non-crop products can be easily screened out. The crop pick-up machine 8) according to any one of 2) to 6), wherein the receiving member pivotally attaches the proximal end of the substantially U-shaped fork to the endless cord, and is a rod-shaped guide member below the tip of the fork. The crop pick-up machine according to any one of the above 2) to 7) having a horizontally supported structure 9) A pick-up device and a sorting conveyor are provided by an output of a rotary shaft interlocked with a rotary shaft for traveling of a power source that travels the machine body. The crop picking machine according to the above 1) to 8) is driven, and the traveling speed of the machine body, the picking device and the conveying speed of the sorting conveyor are increased and decreased in synchronization.
The “substantially square shape” of the sorting conveyor of the present invention means that the planar conveyor path having a circular arc shape at the corner is rectangular or square, or a trapezoidal shape in which the lengths of the front and rear sides or the left and right sides are different. In addition, a shape close to a polygonal shape such as a pentagonal shape and a hexagonal shape, a shape close to a circular shape, and an oval shape long in the feed direction are also included. The “horizontal” of the sorting conveyor means that the crop is held by the weight, inertial force, conveying force or vibration from the receiving member so that it does not fall. There may be a height difference. The “receiving member” of the present invention may be a fork with a gap / opening through which a small non-agricultural crop can be dropped, a net plate, a comb-like object, and a plate-like body with a hole / slit opening. Alternatively, the upper portion may support a crop and a large non-agricultural crop, and the bottom may have a pallet shape for receiving a small non-agricultural crop. Further, the center of the receiving member may be slightly recessed so that the crop can be placed stably.
As the dropping means of the “falling portion” of the sorting conveyor of the present invention, the receiving member may be inclined or suspended vertically so that the crop on the receiving member falls downward, or the upper surface of the conveyor. Alternatively, a scraper plate may be provided to guide only the crops on the receiving member downwardly outside the conveyor path with the scraper plate. Or you may make it move to the outside of a conveyor with the pusher which advances / retreats the crop on a receiving member, and is dropped below.
Examples of the “endless cord” of the sorting conveyor of the present invention include an endless chain, an endless wire, an endless rope, and an endless belt.
The power of the pick-up conveyor / sorting conveyor of the present invention may be the same as or independent from the power for traveling, but the same power (motion system) is fed according to the traveling speed. This is preferable because the speed can be increased or decreased automatically.

  According to the present invention, since the plane shape of the sorting conveyor is substantially square-shaped, the crops and non-agricultural products transferred from the pick-up conveyor are substantially square-shaped front side, one side and rear side conveyors. Since it is sent by the road and put into the lower collection container at the falling part, the sorting operator can be arranged on the back side and one side, and the sorting area by the sorting conveyor operator is the left and right length of the sorting conveyor ( It is a length that is about 1.5 times the length of the rear side) and the length of the side in the feed direction, and is more than about twice the length of the conventional lateral feed conveyor , This will be sorted by two workers, so even if the speed of the airframe (feeding speed of the sorting conveyor) increases, it can be sorted by taking about twice as much transit time. This makes it easier to sort the crops, and the crop pick-up machine's running speed (processing speed) is more than doubled. That. In addition, since it can be left and right without long protrusions, trucks can be transported and self-propelled.

  Also, the base end of the receiving member of the present invention is attached to an endless cable body and is held horizontally by a guide member, and the fall crop is dropped into a collection container by dropping the guide member at a low position or by eliminating the guide member. Can be transported and recovered with a simple structure, and the production cost can be reduced.

  In the invention in which a pair of forks opposed to the receiving member of the present invention is used and the guide member of the outer fork is gradually raised to a higher position at the corner of the sorting conveyor, the outer fork (inward fork) is overlapped at the corner. It can be sent smoothly without becoming.

  In the sorting conveyor according to the present invention provided with a crop fall prevention body at the corner portion, the crop is prevented from falling downward from a large gap generated by the expansion of the receiving member at the corner portion.

  In the receiving member of the present invention, the feed blade protrudes upward, while the crop on the receiving member is being conveyed, the inertia or acceleration force rolls on the receiving member and moves forward or backward to overlap the crop. Prevents squeezing and falling down, and ensures that it can be fed at conveyor speed. Moreover, the fall from the front-end | tip of a receiving member can also be prevented considerably.

The receiving member of the present invention is preferable because a U-shaped fork made of stainless steel having no rust is simple in structure and inexpensive. Further, the endless cord of the sorting conveyor according to the present invention is preferable because the endless chain can reliably feed the receiving member without slipping. The driving can be performed by rotating a sprocket that engages with the endless chain using a part of the traveling power of the airframe. In this case, the traveling speed and the feeding speed of the sorting conveyor can be synchronized.
If the sorting conveyor of the present invention is vibrated, small non-agricultural crops are more likely to fall than the gaps, holes, openings and gaps between the receiving members (forks), and it is preferable to vibrate.

Embodiments of the present invention will be described below with reference to the drawings of FIGS.
The present embodiment is a crop picking machine that uses potato as a crop. The wheel 3 is rotated by the power of an engine 2 that burns fossil fuel, and the body 1 is caused to travel, and the picking device 4 and the sorting conveyor using the same power. 5 is driven. The pick-up device 4 uses a slat conveyor that is inclined so that the front is downward, and the sorting conveyor 5 uses an endless chain 5a that extends horizontally in an approximately rectangular shape as an endless cord, and has a long U-shape as a receiving member. The fork 5b is used. The fork is a U-shaped metal rod that has a base end attached to an endless chain 5a and extends long outward, and a guide member 5c that receives the tip of the fork is provided along the outside of the endless chain 5a. A receiving plate 5f as a crop fall prevention body is provided at the four corners of the endless chain 5a. In addition, one worker who runs and sorts on the rear side of a substantially square-shaped endless chain (sorting conveyor) is placed, and another sorter is placed on the left side of the endless chain (sorting conveyor). In this example, the guide member 5c is lowered at the right side portion of the chain (sorting conveyor) so that the fork 5b is tilted downward to drop the crop on the top.

  In the figure, A is a crop picking machine according to the embodiment of the present invention, B is a crop (potato), and C is a non-crop such as soil and stone. 1 to 6 d are components of the crop picking machine A, 1 is a machine that rotates by driving the wheels 3 with the power of the engine 2, and 4 is a slat installed at the front of the machine 1 so that the front is lowered. Pickup device 5 using a conveyor is a sorting conveyor for conveying and sorting crops having a substantially square shape, the length of the front and rear sides of about 120 cm and the length of the left and right sides of about 130 cm, 5a is an endless chain which is an endless cable body. A large number of base ends of outward U-shaped forks 5b which are receiving members are attached to the endless chain 5a at a constant pitch, and the forks are outside guide members except for the dropping part 5d. 5c holds approximately horizontal. In the dropping portion 5d, the right side guide member 5c is moved inward and lowered so that the fork 5b faces downward at the center of the right side so that the crop B can fall downward. A sprocket gear 5e meshes with each corner of the endless chain 5a, and one of them is rotated by the power of the engine 2 so that the endless chain 5a is sent. Furthermore, a substantially square-shaped receiving plate that is a crop fall prevention body that supports the U-shaped fork 5b substantially horizontally at each corner portion having a substantially rectangular shape and prevents the crop from falling off the fork 5b and falling downward. 5f is provided.

  Here, the space between two parallel bars of the fork 5b, which is a U-shaped bent bar, is about 3 cm and has a gap of 25 mm, from which small non-agricultural crops can fall. The length of the fork 5b is about 24 cm. Then, one bar of the fork 5b is divided into three sections in the longitudinal direction, and a forced feed blade 5g is provided in the fork 5b portion by the width of one section. In addition, the mounting sections of the forcible feed blades 5g of the front and rear forks 5b that are adjacent to each other are different from each other so that the crops do not slip or roll by the forced feed blades 5g of one section, regardless of the position of the fork 5b. So that it can be sent reliably.

  Furthermore, in the embodiment, the guide member 5c is vibrated by the vibration mechanism 6, and the fork 5b whose tip is supported by the vibration of the guide member 5c is subjected to vibration and is placed on the fork 5b. The small non-agricultural crops that have been placed are surely screened out from the gap between the rods of the forks 5b or the distance between adjacent forks 5b by this vibration.

  The vibration mechanism 6 includes an eccentric cam 6b attached to one output shaft 6a of engine power, vibro arms 6c and 6d that receive reciprocation with a small width by the eccentric motion of the eccentric cam 6b, and the vibro arm 6c. , 6d, and the guide member is vibrated up and down through a vibration generator that generates vibration with the reciprocal motion of the reciprocating center being different up and down. The vibration mechanism is not limited to this mechanism, and another mechanism or vibration exciter may be used. In the figure, 7 is a collection box.

  The airframe 1 can travel by driving the left and right large wheels 3 that travel on the ridges, using the engine 2 as a power source in the same manner as a general farm work machine. Although not shown, the distance between the left and right wheels 3 can be adjusted. Further, a front wheel is attached to the front of the aircraft with a variable height (not shown). Thereby, the lower end height of the pickup device 4 is made variable. The operation unit for running the aircraft is attached to the handle. An operation unit for operating the pick-up device 4 by transmitting the power of the engine 2 is also attached to the rear part of the machine body. An operation section for operating / stopping the sorting conveyor 5 is also provided at the rear part of the machine body, and uses the power of the engine 2 as a drive source.

Next, operation and usage of the embodiment will be described.
The potatoes are placed on the topsoil D of the field and dried. The wheel 3 of the crop picking machine A of this embodiment is placed in the grooving of the field, the lower end of the conveyor of the picking device 4 is positioned slightly lower than the topsoil D of the field, and the power of the engine 2 is selected by the wheel 3 and the picking device 4, sorting. When transmitted to the conveyor 5, the machine 1 travels, and the pick-up device picks up the crops placed on the topsoil D of the field and the soil, stones, stems, leaves, etc. together with them, and continuously transfers them to the sorting conveyor 5. To do. The pick-up device 4 is an inclined slat conveyor, and small non-agricultural crops fall considerably in the middle of the pick-up device 4.

  When transferred from the pick-up device 4 to the sorting conveyor 5, both the crop B and the non-crop C are placed on a U-shaped long fork 5b which is a receiving member. Since the fork 5b is held substantially horizontally by the guide member 5c, the crop B and the non-crop C are placed on the fork 5b and conveyed in the counterclockwise direction along with the feed of the endless chain 5a. Since the forced feed blade 5g is attached to the fork 5b, the crop B on the fork is prevented from rolling and moving backward, or sliding and moving backward. It also prevents falling from the fork tip.

  Then, when the fork 5b is fed to the corner portion of the substantially square endless chain 5a, the bending of the endless chain 5a of the arc causes the outward fork 5b to rotate the corner portion so that the interval between the forks is widened. It is sent while. Even if the interval between the forks 5b is widened, the crops on the forks 5b are sent without falling down because there is a receiving plate (a crop fall prevention body) 5f below the corners (see FIG. 4). Also here, the forced feed blades 5g force the crops to slide or roll.

In this way, when the crop reaches the left side of the substantially square endless chain 5a on the sorting conveyor 5, the farmer who is placed here and walks sorts out the large non-farm crop on the fork of the sorting conveyor 5. Exclude. Further, when the crop is sent to the rear side of the substantially square shape, the operator operating the machine selects and removes the large non-crop crop on the fork.
On the other hand, the small non-agricultural crops C fall from the space between the bar shapes of the U-shaped fork 5b of the sorting conveyor 5 and the interval between adjacent forks 5b. This drop is effectively sieved by the vibration of the guide member 5c by the vibration mechanism 6.

  Further, when the guide member 5c passes through the rear side of the sorting conveyor 5 and is sent to the right side and reaches the falling portion 5d, the guide member 5c is lowered toward the inside, so that the fork 5b is inclined downward, and the fork 5b The upper crop is dropped by sliding the fork 5b in the direction of the tip, and is dropped and stored in the collection box 7 disposed below.

As can be seen in this embodiment, even if the traveling speed of the airframe 1 is increased and the feeding speed of the sorting conveyor 5 is increased, each worker is about 1.5 times as long as one side of the substantially square-shaped sorting conveyor. Since it is only necessary to sort within the length range, even if the conveyor feed speed is high, the conveyor sorting range is long, so it is sufficient to sort with a long passage time, so that the sorting operation can be performed with a lot of space.
Moreover, the sorting conveyor extends to the left and right to the same extent as a conventional crop picking machine, and there is no hindrance to the truck picking up the truck and the self-running on the road.

The sorting conveyor shown in FIGS. 7 to 9 is an example of another fork-type sorting conveyor. The endless chain is doubled in a generally square shape inward and outward, and the inner endless chain 15a has a short outward U-shape. A fork 15c is attached, a short U-shaped fork 15d is attached to the outer endless chain, and the two forks 15c, 15d are opposed to each other so that their tips do not contact each other, and with the two forks 15c, 15d This is a receiving member for the crop B and the non-crop C.
In this example, the guide members 15e and 15f are disposed below the front ends of the forks 15c and 15d and are held so that the front ends are slightly lower than horizontal.

  In this example, the guide member 15i at the corner portion is gradually raised so as to be the highest at the center of the corner so that the outer inward forks 15d do not contact each other at the corner portion, and then the outer fork 15d overlaps without the guide member. Like that. Even if they overlap, there is no problem in feeding. After that, the guide member 15f returns the fork 15d to a height that holds it approximately horizontally. As a result, the inwardly facing forks 15d at the corners have different heights at the corners, and the forks 15d hit each other on the same plane to prevent them from moving and make the corners smooth. There is no problem because the inner outward forks 15c spread out and do not contact each other. In addition, since there is a receiving plate 15g (a crop fall prevention body) below the corner portion, the crop B does not fall (see FIG. 9).

Further, the tip of the fork 15c, 15d facing the drop part 15h in this example is inclined downward, and the crop B falls between the tip parts into the lower collection box 7 (FIG. 8). reference).
The other structure is the same as that of the said Example.

  Although the present invention is an apparatus for picking up crops on the topsoil of the field, it can also be used as an apparatus for digging out and sorting and sorting the crops in the field soil. Alternatively, by removing the pick-up conveyor device and providing a crop supply conveyor, it can also be used as a stationary, non-traveling sorting / sorting device on the ground.
