  If the entire shooter 67 or the portion of the shooter 67 where the foliage drop slit 67a is formed is made of a soft member made of rubber, synthetic resin, or the like, the taro T can be prevented from being damaged when taken over. , And the protrusions 49a provided on the bar conveyor 49 are prevented from being caught, so that the foliage and the like caught in the foliage drop slit 67a can be dropped. The foliage and weeds are prevented from entering the sorting and conveying apparatus F, and maintenance work such as cleaning of the sorting and conveying apparatus F is simplified, and the labor of the operator is reduced. Moreover, it is good also as a structure which coats the part which forms the foliage fall slit 67a among the shooters 67 with the soft member which uses mu or synthetic resin etc. as a raw material. At this time, it is effective to apply a thick coating of the soft member.

  Moreover, the machine part of the raising / lowering cylinder 68 which raises / lowers the excavation conveyance conveyor 50 to the main frame 1 is attached, and the end part of the raising / lowering cylinder 68 is located between the left and right side covers 42 and 42 and below the excavation conveyance conveyor 50. The excavating and conveying apparatus D is configured by attaching to the provided support frame 69 and connecting the elevating cylinder 68 and the first hydraulic valve 8 with an oil feeding cable or the like.

The elevating cylinder 68 of the present embodiment is a hydraulic cylinder, but the same effect can be obtained even if it is replaced with an expansion / contraction member such as an air cylinder or an electric cylinder.
According to the above configuration, by digging up the taro T from the ground with the digging bar 53 at the tip, the taro T can be digged up without bringing the digging and conveying conveyor 50 into contact with the field scene. Since the transport motor 45 and the drive shaft 44 that drive the motor 50 are overloaded and prevented from being damaged, the durability of the machine body is improved.

  Further, since the bent portion 54 is formed at the tip of the digging bar 53, mud mud that is dug up together when digging up the taro T can be guided in the lateral direction of the machine body. Contact with the digging and conveying conveyor 50 is prevented from obstructing the straight advance of the machine body, so that the work efficiency is improved, and the mud is prevented from preventing the taro T from being dug up, thereby improving the work efficiency.

  Then, by attaching a plurality of mud dropping claws 55a ... and a plurality of auxiliary mud dropping claws 55b ... between the digging bar 53 and the conveyance start end of the digging conveyance conveyor 50, the digging bar 53 digs up. When the taro T is handed over to the digging and conveying conveyor 50, the mud soil adhering to the taro T can be dropped from between the mud dropping claw 55a ... and the auxiliary mud claw 55b ..., thereby improving the product value of the taro T At the same time, the mud is prevented from interfering with the separation of the relatives Tp and the child Tc in the first separation device E and the second separation device G, which will be described later, and the separation work efficiency is improved.

  Further, by bending the rear end of the mud dropping claw 55a and the auxiliary mud dropping claw 55b downward, the distance at which the taro T falls to the digging and conveying conveyor 50 is shortened, and the taro T is bent at the bent portion. Since it can be slid down, the taro T is prevented from being damaged by the impact of dropping, and the product value of the taro T is improved, and the work efficiency is improved because the taro T is smoothly transferred to the sorting conveyor 50.

  Furthermore, by attaching the auxiliary mud dropping claw 55b below the mud claw 55a ..., it is possible to drop the mud soil attached by vibrating the taro T, so that the commercial value of the taro T is improved, The mud is prevented from interfering with the separation of the relative Tp and the child Tc in the first separation device E and the second separation device G, which will be described later, and the separation work efficiency is improved.

  In addition, since the mounting positions of the left and right connection plates 52, 52 for attaching the digging rod 53 can be changed in the longitudinal direction of the machine body, the digging rod 53 can be placed at an optimum position for work conditions such as varieties of taro and field conditions. Since the digging position can be changed, work efficiency is improved.

  Since the mounting positions of the left and right gauge wheel arms 62 and 62 to which the left and right gauge wheels 63 and 63 are rotatably attached can be changed in the longitudinal direction of the aircraft, the longitudinal width of the aircraft can be made compact. This makes it easy to store the aircraft in a vehicle or to load the aircraft into a transportation means such as a light truck.

  In addition, since the ground contact position of the left and right gauge wheels 63, 63 can be changed to a position optimal for work conditions such as varieties of taro T and field conditions, the transport posture of the excavation transport conveyor 50 is stabilized, and the work efficiency is improved. Will improve.

  Further, conventionally, since the space between the left and right driven sprockets 46, 46 is a space, a plurality of convex bodies 49a attached to the bar conveyor 49 collect mud mud dug together with the taro T, and the left and right driven sprockets 46, 46 46 has a drawback that the rotation of the digging and conveying conveyor 50 is hindered or stopped, but by attaching the collar 47 between the left and right driven sprockets 46, 46, mud Since the collar 47 presses the mud against the field scene before it becomes a lump or sends it back, the digging and conveying conveyor 50 can be prevented from stopping, so that the work efficiency is improved.

  Further, since the sorting conveyor 50 is constituted by the bar conveyor 49, the mud adhering to the taro T can be dropped from between the rod bodies, so that the commercial value of the taro T is improved and will be described later. The mud is prevented from interfering with the separation of the relative Tp and the child Tc in the first separation device E and the second separation device G, and the separation work efficiency is improved.

  A plurality of gate-shaped convex bodies 49a... Are attached to the bar conveyor 49 at equal intervals, so that the convex body 49a can be formed even if the taro T, the separated relatives Tp, and the child Tc fall down during transportation. Since the taro T, the relative Tp, and the pupa Tc are received, the taro T, the relative Tp, and the pupa Tc can be prevented from falling on the field, so that the taro T, the relative Tp, and the pupa Tc are damaged by the impact of the fall. Is prevented and the product value is improved, and the work of collecting the taro T, the relative Tp, and the child Tc that have fallen into the field is omitted, so that the labor of the operator is reduced.

  Further, by providing a large number of conveying claws 49c bent in a U-shape in a plan view at the front ends of the convex bodies 49a ... and the rotating convex bodies 49b ..., the conveying claws of the convex bodies 49a ... and the rotating convex bodies 49b ... 49c, the mud claw 55a, and the auxiliary mud claw 55b can be reduced, the taro T can be handed over smoothly, and digging and transporting can be performed while reducing damage.

If the conveying claws 49c are made of an elastic material, damage to the taro T can be reduced.
Further, by attaching a swinging device 60 for swinging the sorting conveyor 50 behind the first separating device E, which will be described later, the relatives Tp and child Tc separated by the first separating device E are vibrated and attached. Since the muddy mud can be dropped, the product value of the relatives Tp and the child Tc is improved, and the efficiency of the sorting operation on the sorting transport table 96 is improved. In the case of a product that does not use the relative Tp as a product, the product value of only the child Tc is improved.

Further, in the configuration of the present embodiment, since the separation action portion α of the first separation device E that separates the taro T does not swing, the separation work posture can be stabilized, so that the separation work efficiency is improved.
And, by attaching the shooter 67 to the terminal portion of the digging and conveying conveyor 50, the sorting and conveying table 100, which will be described later, is completely separated from the digging and conveying conveyor 50 by the relatives Tp and the ridges Tc and the first separation device E. Since no taro T can be taken over without dropping, the taro T, the relative Tp and the child Tc are prevented from being damaged, and the commercial value is improved.

  Further, by forming the foliage drop slit 67a and the mud fall slit 67b in the shooter 67, the foliage, weeds and mud can be dropped from above the shooter 67, so that the foliage and the weeds will be described later. Since the maintenance work such as cleaning of the sorting and conveying device F is prevented, the labor of the operator is reduced and the amount of mud entering the sorting and conveying device F is reduced. Since it is possible to prevent erroneous sorting of dredged Tc and mud, work efficiency and sorting accuracy are improved.

  Further, the shooter 67 is provided so as to be rotatable, and the shooter 67 is pulled downward by the spring 87 so that the inclined posture of the shooter 67 changes following the change in the working posture of the digging and conveying conveyor 50. Since the working posture of the digging and conveying conveyor 50 can be changed according to the working conditions without changing the difference between the head and the sorting and conveying table 100, the taro T, the relative Tp, and the child Tc may be damaged by the impact of the drop. As a result, the product value is improved and the transport of the taro T, the relative Tp, and the child Tc from the digging transport device D to the sorting transport device F is performed without stagnation, so that the work efficiency is improved.

  Further, by arranging the control seat 65 in the vicinity of the side of the terminal end portion of the excavation transport conveyor 50, the pilot operator can sit on the work seat 65 and perform the excavation transport conveyor 50, the sorting transport platform 96 described later, and the second separation. Since it can face the apparatus G side, the relative Tp is removed at the end of the excavating and transporting conveyor 50, or the relative Tp and the child Tc are sorted by the sorting carrier 96 together with the auxiliary worker, or the relative is completely Since the taro T in which the Tp and the pupa Tc are not separated can be installed in the second separation device G and the separation work can be performed, the work efficiency is improved.

  In addition, since the traveling speed at the time of the work of the crop separating and harvesting machine of the present embodiment is extremely low, the operator can move safely even if he / she does not always perform the operation, so the above-described sorting operation, etc. There is no problem with safety.

Arrange in the direction (staggered arrangement).

  At this time, if the upper bar 90a and the lower bar 91a are arranged at equal intervals in the vertical direction and the front and back, the relatives Tp and the child Tc are located at any position on the transport path of the sorting transport device F. Since the upper bar body 90a and the lower bar body 91a can be evenly contacted, the mud and the foreign matter adhering to the relative Tp and the child Tc can be efficiently dropped from the respective fall spaces S1 and S2. .

  Further, when the front and rear distances between the upper rods 90a and the lower rods 91a are widened toward the front side in the transport direction and narrower toward the rear side in the transport direction, the diameter increases due to adhesion of mud and foreign substances. On the conveying start end side of the sorting and conveying apparatus F, the number of times the relatives Tp and the child Tc are in contact with the upper bar body 90a... And the lower bar body 91a is increased and mud and impurities are efficiently removed. On the conveyance end side where the contaminants are dropped into the fall spaces S1 and S2 and the diameters of the relatives Tp and the child Tc are reduced, a small child Tc falls between the upper bar 90a and the lower bar 91a. Can be prevented.

  The left and right swing guides 94, 94 may have any shape other than the concave shape as long as it does not impair the swing of the sorting and conveying device F, such as a U shape, a circular shape, and an elliptical shape.

The swinging device 105 is configured by winding the moving chain 98 endlessly.

  Further, an output adjusting device 99 for changing the rotational speed of the swing selection motor 97 and turning on / off the rotation driving force is attached to the left and right sides of the left and right rear supports 88R, 88R. By connecting the hydraulic valve 14 with an oil feeding cable or the like and connecting the output adjusting device 99 and the swing sorting motor 97 with an oil feeding cable or the like, the sorting and conveying table 100 is configured. Further, left and right fall prevention guides 101 and 101 for preventing the taro T, the relatives Tp and the child Tc from dropping while being sorted and conveyed to the sorting and conveying device F are attached to the upper portions of the left and right sorting and conveying frames 89 and 89, respectively. The left and right discharge guides 102 and 102 are attached to the rear inner sides of the left and right fall prevention guides 101 and 101, respectively.

  Further, an adjustment cover 103 made of a soft member made of rubber, resin, or the like having a hollow cylindrical shape and a cut in the left-right direction of the machine body is formed on each of the plurality of upper bar bodies 90a. The sorting and conveying device F is configured by being detachably attached.

  According to the above configuration, the upper selection body 90 provided with a plurality of upper bar bodies 90a, and the lower selection body 91 provided with the lower bar materials 91a ... As a result, the upper rod 90a and the lower rod 91a are moved in contact with each other many times when the sorting and conveying table 100 on which the relative Tp and the child Tc swing is moved. Therefore, since mud adhering to the relative Tp and the child Tc can be dropped from the fall spaces S1 and S2, the commercial value of the relative Tp and the child Tc is improved, and the relative Tp and the child Tc are easily visible. Therefore, missorting is prevented and the efficiency of sorting work is improved.

  Then, by attaching the adjustment cover 103 that is detachable by providing cuts to the plurality of upper bar bodies 90a and the lower bar bodies 91a, the plurality of upper bar bodies 90a and the lower bar bodies 91a are provided. Since the interval becomes small, it is possible to prevent the pod Tc being sorted and transported from falling downward when harvesting varieties having small grains, so that the lash Tc is prevented from being damaged by the impact of the fall. As a result, the product value of the crop is improved, and the work of collecting the pupae Tc dropped after the work is omitted, so that the labor of the worker is reduced.

  Further, when the adjustment cover 103 is attached, the taro T, the relative Tp, and the child Tc do not adhere to the plurality of upper rods 90a, the lower rods 91a, etc., so the taro T, the relative Tp, and the child Tc. Can be prevented from coming into contact with the upper rod body 90a ... and the lower rod body 91a ... so that the commercial value of the taro T, relative Tp, and child Tc is improved, and the taro T, relative Tp, and child Tc are improved. Since the adhering mud adheres to the adjustment cover 103..., The time required for cleaning the sorting and conveying device F can be shortened, and the work efficiency is improved and the labor of the operator is reduced. The mud soil adhering to the adjustment cover 103 may be removed by washing with the adjustment cover 103. At this time, if the consumable one is replaced with a new one, the adjustment cover 103 will be damaged during the work and the work efficiency will be improved. Can be prevented. In addition to the above effects, the upper rod 90a ... and the lower rod 91a ... are prevented from being consumed by contact with the taro T, relative Tp, child Tc, or mud, so the upper rod 90a ... The rods 91a can be made of a highly durable metal or hard plastic, and the durability of the sorting and conveying apparatus F is improved.

  Further, by removing the adjustment cover 103 from the plurality of upper bars 90a and the lower bars 91a, when harvesting varieties having large grains, the taro T, relatives Tp, and pups Tc are used. When the adhering mud lump is large, the space between the upper rod 90a and the lower rod 91a can be increased, so that the relatives Tp and the child Tc are separated from the upper rod 90a and the lower rod 91a. ... and can remove the adhering mud efficiently, and even a large mud lump can be dropped, so mistakenly identify the mud lump as a relative Tp or a child Tc. Since erroneous sorting is prevented, the efficiency of sorting work is improved and the accuracy of sorting is improved.

  In this embodiment, the adjustment cover 103 is made of a soft member made of rubber or resin in order to enhance the damage effect of the relative Tp and the child Tc. However, the adjustment cover 103 is made of a cloth having an appropriate flexibility. It may be composed of a fiber material such as paper, or a leather material such as synthetic leather or animal skin, and metal, concrete, hard plastic or the like may be used when harvesting a thick and durable variety.

  Further, in the present embodiment, the adjustment cover 103 is made to be detachable, but as shown in FIG. 11, it is divided into two or more adjustment covers 103a, 103b and connected to the upper bar 90a. May be configured to cover the upper bar 90a and the lower bar 91a as a thread-shaped adjustment cover 103c as shown in FIG.

  Further, the adjustment covers 103 are not necessarily required to be attached to all the upper rods 90a and lower rods 91a, and are provided on the sorting and conveying start end side where a large amount of mud adheres in order to reliably remove mud. The operator may freely set such that it is provided at the sorting and conveying end, or provided at the sorting and conveying start and end, or randomly.

  Since the sorting transport table 100 is configured to be swingable by the swinging device 105, the attached mud soil can be dropped by shaking the relative Tp and the child Tc, so that the commercial value of the relative Tp and the child Tc can be reduced. While improving, it becomes easy to visually recognize the relative Tp and the child Tc, so that the efficiency of the sorting operation is improved. Furthermore, since the relatives Tp and the child butt Tc can be moved to the rear part of the machine body, it is not necessary for the worker to manually collect the relatives Tp and the puppy Tc, and the labor of the worker is reduced.

  In addition, since the left and right rear columns 88R and 88R are configured lower than the left and right front columns 88F and 88F, the sorting and conveying table 100 is inclined backward, so that the relatives Tp and the child Tc are automatically moved to the rear part of the body. Therefore, it is not necessary for the operator to manually collect and the labor of the operator is reduced.

  Further, by providing an output adjusting device 99 that adjusts the rotation speed of the swing selection motor 97 and turns on / off the power transmission, the output is increased when a lot of mud adheres to the relatives Tp and the relatives Tc. Thus, the swinging width of the sorting carrier 100 can be increased, so that the commercial value of the relative Tp and the child Tc is improved, and the relative Tp and the child Tc are easily visible, so that the efficiency of the sorting operation is improved.

  In addition, when the swinging width is large and hinders the sorting operation, the output can be reduced to reduce the swinging width of the sorting transport table 100. Therefore, the relatives Tp and the child's Tc can be easily visually recognized. As well as improving, the sorting operator can work safely.

  Furthermore, since only the sorting / conveying device F can be stopped according to the working state, the sorting and conveying table 100 can store the taro T, the relatives Tp, and the child's Tc, and can accommodate containers, bags, etc. The replacement work of the member 104 can be performed efficiently.

  Further, by providing the left and right fall prevention guides 101, 101 at the upper part of the left and right sorting transport frames 89, 89, the taro T and relatives Tp swung to the left and right of the sorting transport table 100 due to the swinging of the sorting transport table 100. Since it is possible to prevent the fallen child Tc from falling, the work of collecting the taro T, the relative Tp, and the child Tc is omitted, and the labor of the worker is reduced.

  Further, since the left and right discharge guides 102 and 102 are provided, even if the relatives Tp and the child Tc are scattered on the entire surface of the sorting transport table 100, the left and right discharge guides 102 and 102 can set the discharge position of the terminal end of the sorting transport table 100. Since it can be regulated and discharged only from a certain range, the puppet Tc can be reliably accommodated in the accommodating member 104 such as a container or a bag, and the work efficiency is improved.

  Further, since the relatives Tp and the pupae Tc are prevented from falling from the sorting and conveying device F to the field, the relatives Tp and the pupae Tc are prevented from being damaged by the impact of the fall, and the relatives Tp and the pupae Tc are prevented from being damaged. The merchandise value can be improved, and the labor of picking up the relatives Tp and the cubs Tc that have fallen into the field is omitted, thereby reducing the labor of the operator.

Next, the second separator G will be described.
As shown in FIGS. 1, 2, 17, and 18, a cover frame 106 is attached above the first engine 2 and the fuel tank 3, and outside the left and right sorting transport frames 89 and 89 and on the left and right front struts. The left and right middle struts 107 and 107 are attached to the rear of the 88F and 88F, and the connecting frame 108 is attached between the left and right of the left and right struts 107 and 107 and above the sorting and conveying table 100. Then, a support frame 109 is attached to the upper part of the cover frame 106 and the inside of the body of the connecting frame 108, and a child Tc and a remnant of the relative Tp are placed on the rear part of the support frame 109 in the longitudinal direction of the body to the sorting and conveying table 100. A shooter 110 to be moved is attached. In addition, a U-shaped separating device frame 111 is attached above the supporting frame 109, the right supporting column 107, and the connecting frame 108, and a taro T is mounted on the front side projecting portion below the separating device frame 111. A cylindrical mounting table 112 to be placed is attached, and a ring 113 for scraping off the lever Tc is attached to the outer periphery of the upper end portion of the mounting table 112. Further, a plurality of cutting blades 114 for cutting and crushing the relative Tp are attached to the inside of the mounting table 112.

  In addition, when the cutting blades 114 are mounted with their bases on the inner peripheral edge of the mounting table 112 and arranged with their tips facing each other at substantially the center of each of the cutting blades 114, the remnants of the cut and crushed relatives Tp It becomes easy to fall down. When the number of the cutting blades 114 is about 4 to 6, it is difficult to obstruct the removal of the remnants of the relative Tp.

  Then, a separation cylinder 115 that is telescopically attached to the upper front side of the body of the separation device frame 111 and above the center of the mounting table 112 is attached, and the separation cylinder 115 and the first hydraulic valve 8 are connected by an oil feeding cable or the like. Link. In addition, a columnar pressing member 116 is attached to the lower end portion of the separation cylinder 115 to press the parent Tp installed on the mounting table 112 and scrape off the child Tc with the ring 113. A plurality of pressing members 116 are attached to the lower portion of the pressing member 116. The second separating device G is configured by attaching the eight-shaped pressing protrusions 117 in a plan view.

  The separation cylinder 115 is configured to be detachable and at least one mounting claw 155 having a width capable of fitting the separation cylinder 115 of the second separation device G onto the separation device frame 111 is attached. When the separation cylinder 115 is detached from the separation device frame 111 and the separation cylinder 115 is fitted into the mounting claw 155 when storing the machine body, the vertical height of the machine body can be kept low. Therefore, it is possible to prevent the damage to the body and the contacted object due to the contact.

  Also, as shown in FIGS. 2, 7, 8, and 16, by attaching a separation protrusion 118 to the upper portion of the connecting frame 108, the sorting worker manually separates the relative Tp and the small child Tc. A third separator I for separating the taro T that has not been separated is configured.

  According to the above configuration, the taro T, which has not been completely separated into the relative Tp and the child Tc by the first separation device F, is placed on the mounting table 112 and pressed by the separation cylinder 115 to the relative Tp.

Further, by cutting the relative Tp pushed into the mounting table 100 with a plurality of cutting blades 114 and discharging it downward, the next taro T can be installed without removing the relative Tp from the mounting table 112. So work efficiency is improved.
Since the relatives Tp are cut and crushed by the plurality of cutting blades 114, the relatives of the relatives Tp are easily rotted and the size of each residual is reduced. When the field is cultivated with a tractor or the like, the debris of the relative Tp can be crushed into the soil while being finely crushed, so that natural nutrients can be supplied to the field and the soil quality of the field can be improved.

  Furthermore, finely broken fragments of relatives Tp are decomposed before becoming a hotbed for breeding fungi and viruses that cause continuous cropping failure, and become nutrients for the field. The soil quality can be improved.

  If the relatives Tp are left in the field without being crushed, it will be difficult for the rotting to progress, and even if it tries to enter the field during the cultivation work, the fragments of the relatives Tp will remain in the field and cause the continuous cropping failure. In addition to the disadvantage that it becomes a hotbed for breeding fungi and viruses to reduce soil quality, debris will emerge after heavy rain or when water is pulled to make rice paddies, scraping work with tractors etc. Since there is a possibility that fragments of relatives Tp may interfere with seedling planting work by a machine, etc., there is a drawback in that it is necessary to manually remove relatives Tp floating on the field, which causes the worker to spend extra labor. is there.

Since the taro T that has not been completely separated can be taken and installed in the second separation device G, the separation work can be performed, so that the work efficiency is improved.

  Further, by attaching a pressing member 116 having a plurality of pressing protrusions 117 to the lower end portion of the separation cylinder 115, the pressing protrusions 117 prevent the pressing member 116 from slipping even if the pressing portion of the relative Tp is a curved surface. Therefore, the relative Tp can be surely pushed into the mounting table 112, so that the efficiency of the separation work is improved.

  Further, by configuring the third separation device I above the sorting and conveying table 100, the relatives Tp and the child's Tc separated by the separation protrusion 118 can be dropped onto the sorting and conveying table 100, so that the operator can Sorting work can be performed immediately, and work efficiency is improved.
