2. Description of the Related Art Conventionally, in carrot harvesting as a root vegetable harvesting machine, as shown in FIG. 4, a bag suspending tool 31 and a bag receiving tool 32 are provided below the end of the conveyor 7, and the bag suspending tool 31 is provided. Even when carrying out a harvesting operation by supporting a large-sized storage bag 8 having a deep bottom, carrots are broken by the impact of falling from the conveyor 7 by causing the bag receiver 32 to be received by the bottom of the storage bag 8 and adjusting the swing. I was trying to avoid being damaged or damaged. That is, FIG.
As shown in (a), when the empty storage bag 8 is attached,
By raising the bag receiver 32 in a horizontal position and lifting the bottom of the storage bag 8 close to the conveyor 7, carrots from the conveyor 7 are not easily scratched even if they fall onto the carrots in the bag. The drop from the conveyor 7 to the bottom of the storage bag 8 is kept small. Then, when the carrots in the bag increase and the storage space of the storage bag 8 decreases or disappears, as shown in FIG. 4B, the storage space remaining in the storage bag 8 and the size of the storage bag 8 are increased. The bottom of the storage bag 8 is moved to the conveyor 7 by adjusting the bag receiver 32 downwardly by an appropriate angle according to the height.
Thus, the space from the conveyor 7 to the ginseng in the bag is prevented from being damaged by the drop impact of the ginseng, while forming a space for the ginseng to enter the storage bag 8.

[0003]

The above-described conventional damage avoidance technique has a problem that damage occurs on a surface different from the drop from the conveyor to the storage bag. That is, when the bag receiver is adjusted downward, especially when the descending angle of the bag receiver becomes a steep angle, as shown by the chain double-dashed line in FIG. Due to the inclination of the bag receiver 32, the bottom portion of the storage bag 8 slides out of the bag receiver 32 and protrudes outward, and when the bag slides out of the bag receiver, the carrot in the bag is at the end of the bag receiver. It could be scratched and damaged. Also, when the storage bag is full, the overall shape becomes distorted and the amount that can be stored is reduced, or when the bag is removed from the hanging tool and placed on the ground etc., it becomes unstable and it is difficult to stand. The situation sometimes occurred. An object of the present invention is to provide a root vegetable storage unit that can collect root vegetables such as carrots in a storage bag with a deep bottom so that they are not easily scratched and that troubles such as deformation of the storage bag do not occur. To do.

The constitution, operation and effect of the present invention are as follows.

[Structure] In a root vegetable storage unit structure of a root vegetable harvester equipped with a pretreatment device for extracting root vegetables from a field and taking them in, and a conveyor for conveying and dropping the root vegetables from the pretreatment device into a storage bag, the storage A bag support for suspending and supporting the bag is swingably attached to a support member so as to support the bag mouth portion of the storage bag and swing up and down,
As the bag supporter rises and oscillates from the lowermost position, the transport end side of the conveyor enters the inside of the storage bag, and the rising angle of the bag supporter from the lowermost position increases. The conveyor is configured to have a long insertion length into the storage bag, and is provided with an adjusting mechanism for adjusting the attachment angle of the bag support.

[Operation] When the empty storage bag is mounted, the bag support is adjusted to the mounting posture on the rising side by the adjusting mechanism. Then, the conveyor end side of the conveyor penetrates deeply into the bag and the bottom of the storage bag approaches the conveyor.Therefore, the drop from the conveyor to the bottom of the storage bag is the same as when the bottom of the storage bag is lifted by the conventional bag receiver. It becomes small, and even if root vegetables from the conveyor fall on the root vegetables in the bag, root vegetables collection can be started while preventing damage. Then, when the amount of collected root vegetables increases and the bag storage space decreases or disappears, the bag support is lowered and adjusted by the adjustment mechanism so that the bag support is lowered by a predetermined angle according to the depth of the storage bag. , Resume root vegetable collection. That is, when the bottom of the storage bag is relatively shallow, the bag support is immediately adjusted to the stroke end and the root vegetable collection is restarted. Then, when the bottom of the storage bag is deep, first adjust the mounting posture down to the stroke end and resume root vegetable collection after this.
When the bag storage space becomes small or runs out, the bag support is lowered down to the stroke end again. Collect root vegetables. Then, if the bottom of the storage bag is shallow, even if the bag support is lowered all the way to the stroke end, all the parts on the conveyor end side that had entered the storage bag until then come out of the storage bag. In addition, the shallow bottom of the storage bag forms a space for the root vegetables to enter the storage bag while reducing the drop from the conveyor to the root vegetables in the bag, and the root vegetables from the conveyor fall onto the root vegetables in the bag, but it is damaged. It is possible to collect root vegetables until the bag is full, while it is less likely to occur. Then, when the bottom of the storage bag is deep, the bag support is not lowered all the way to the stroke end, but by adjusting the descent in several steps, when performing the descent adjustment and restarting the root vegetable collection, Each time, the end part of the conveyor, which had been in the storage bag, comes out of the storage bag for the length corresponding to the downward adjustment stroke of the bag support, and stores it while reducing the drop from the conveyor to the root vegetables in the bag. The root vegetables will be collected by forming a space for the root vegetables in the bag, and finally the bag support is adjusted down to the stroke end so that all the conveyor end side parts come out of the storage bag. The root vegetables will be collected. Thereby, even in the case of a bag having a deep bottom, it is possible to collect root vegetables until the bag is full, while preventing the root vegetables from the conveyor from dropping onto the root vegetables in the bag from being damaged. The bag supporting device adjusts the head by supporting the containing bag such that the bottom side of the bag always hangs and moving the bottom toward or away from the conveyor.

[Effect] By adjusting the drop from the conveyor to the root vegetables in the bag so that damage due to a drop impact is less likely to occur, the bag can always be collected from the bag support and the storage bag always hangs down. By adjusting the drop while avoiding the occasional rubbing, even in the case of a large bag with a deep bottom, the root vegetables can be collected in a high quality state with no damage.
In addition, since the storage bag is always hanging down, as the root vegetables enter, the bag becomes the original shape due to its weight and pressure, and it can be efficiently collected by packing the amount of root vegetables according to the capacity of the bag and filling it up. The new bag can now be placed on a stable surface and can be handled easily, making it possible to work in an advantageous manner. Moreover, the conventional bag holder moves up and down while maintaining the horizontal state to prevent the storage bag from slipping out easily.
Compared to a pantograph type link mechanism for modifying the support structure of the bag receiver, a simple modification of changing to a swingable bag support was sufficient, and it was possible to obtain an economical advantage.

The work deck 3 comprises a slat conveyor that transfers the root vegetables C from the lifting conveyor 6 to the rear of the machine by inheriting it at the upper U-turn portion of the lifting conveyor 6.
A sorting conveyor 7 for placing and transporting the root vegetables C so that a worker who rides on the root can carry out the sorting work, and a root vegetable storage unit configured to store the root vegetables C from the sorting conveyor 7 in a storage bag 8. A root vegetable harvesting machine is configured by equipping 20 with a self-propelled aircraft.

A pretreatment frame 10a is connected to the self-propelled body so as to be vertically swung around the axis R1 by the lift cylinder 4, and the pretreatment frame 10a is connected.
A pair of left and right weeding tools 11, 11 and raising devices 12, 12 and earth cutting blades 13, 13 are attached to the front end side of the, and a mustache root cutting device 14 is attached, and the pretreatment frame 1
Drawing transmission case 15 extending rearward from the front end side of 0a
A pair of left and right extraction endless rotating belts 15 and 1 are provided below a.
The pretreatment device 10 is provided with 5, a positioning transport device 16, a cutting transport device 17, a pair of left and right drive rotary blades 18, 18, and a foliage transport device 19. The weeding tool 11 and the raising device 12 are the root vegetables C to be extracted.
And the foliage portion F of the non-pulling-off target root vegetable C are divided, and the foliage portion F of the non-pulling-out target root vegetable C is caused to be treated. The soil cutting blade 13 breaks down the soil on both sides of the extraction-target root vegetable C to facilitate extraction of the root vegetable C. The pair of pull-out endless rotation belts 15 and 15 sandwiches the foliage portion F of the root vegetable C from the weeding tool 11 and the raising device 12 and hangs and transports the root vegetable C obliquely upward and rearward so that the root vegetable C is removed from the field. Pull it out and transport it backwards and upwards. As the pull-out endless rotating belt 15 suspends and conveys the root vegetables C pulled out from the field, the beard root cutting device 14 causes the root vegetables C to move.
It acts on the mustache root extending from the lower end of the to remove and remove this mustache root. When the pulling-out endless rotation belt 15 suspends and transports the root vegetables C further to the rear side of the machine, the positioning and conveying device 16 that aligns the head position of the root vegetables C to a fixed position causes the head of the root vegetables C and the pulling-out endless rotation belt 15 to move. The feeding endless rotation belt 15 pulls up the feeding root vegetable C due to the difference in inclination angle between the pulling endless turning belt 15 and the positioning feeding device 16 while acting on the foliage portion in between. As a result, the positioning and conveying device 16
Positions the conveyed root vegetable C so that its head has a predetermined positional relationship with the rotary blade 18. After that, the root end C from the pull-out endless rotating belt 15 and the positioning transfer device 16 is taken over by the cutting transfer device 17 and transferred to the rear of the machine body to supply the foliage F to the rotary blade 18, so that the rotary blade 18 is The foliage F of the root vegetable C is cut at the root. When this cutting process is completed, the cutting conveyance device 17 drops and supplies the root vegetables C to the conveyor 5 and the foliage portion F to the foliage portion conveyance device 19. The foliage transporting device 19 is composed of an endless rotating chain 19a for transporting which can be freely driven and a nipping rail 19b. The foliage F is squeezed from the cutting transporting device 17, is transported to the front side of the machine body, and falls into the field. discharge. As a result, the pretreatment device 10 pulls out the root vegetable C from the field, removes the foliage portion F from the field, and takes it into the rear side of the machine body.

The root vegetable storage unit 20 has a pair of left and right bag-hanging rods 21a, 21a and a connecting rod 21b connecting the leading end sides of both bag-holding rods 21a, 21a so that the conveying end side of the sorting conveyor 7 is A bag support 21 formed in a U shape so as to be able to enter the inside of the storage bag 8 from between the two bag hanging rods 21a, 21a is provided on the support of the sorting conveyor 7 at the base end portions of the two bag hanging rods 21a, 21a. Combined support member 22
Is mounted so as to swing around the axis X in the lateral direction of the machine body, and cylinders 23 mounted across the bag hanging rod portion 21a and the support member 22 are provided on both lateral sides of the bag support tool 21. . Then, as shown in FIG. 3, while adjusting the swing of the bag support tool 21, the sorting conveyor 7
It is configured to be dropped and supplied from the container to the storage bag 8 to be collected.

That is, the attachment cord 8a attached to the bag mouth of the storage bag 8 is hooked on the plurality of cord hooking pins 24 provided on the pair of bag hooking rods 21a, 21a to attach the bag support 22. The pair of cylinders 23, 23 is used to adjust the swing to a predetermined mounting posture, and the storage bag 8 and the root vegetables C are fixed so that they do not descend even if the weight thereof is applied.
The bag support 21 suspends and supports the storage bag 8 at its bag mouth, and allows the root vegetables C to be dropped and supplied from the selection conveyor 7 to the storage bag 8. When the pair of cylinders 23, 23 is expanded and contracted, both cylinders 23, 23 move the bag support 22 so that the conveying end side of the sorting conveyor 7 moves in and out between the bag hanging rods 21a of the bag support 21. By swinging the bag support 21 up and down around the core X, the carrying end side of the sorting conveyor 7 is moved to the storage bag 8 as the bag support 21 is lifted from the lowest position D in which the bag support 21 is in a horizontal or substantially horizontal mounting posture.
As the bag support 21 moves upward from the lowermost position D, the length of the sorting conveyor 7 entering the storage bag 8 increases.

Then, as shown in FIG. 3A, when the empty storage bag 8 is mounted, the bag support 21 is attached to the cylinder 23.
By the upward swinging operation, the conveyance end side of the sorting conveyor 7 is adjusted to the first mounting posture U in which the inside of the storage bag 8 is inserted for a long time, and root vegetable collection is started. Then, the bottom of the storage bag 8 is lifted up near the conveyance end of the selection conveyor 7, the storage bag 8 is empty, and the depth from the bottom of the storage conveyor 8 is small because of the drop from the selection conveyor 7 to the bottom of the storage bag 8. Therefore, even if the root vegetables C supplied from the sorting conveyor 7 fall on the root vegetables C already collected in the storage bag 8, the root vegetables C caused by this drop impact.
Is dropped into the storage bag 8 in a state in which it is less likely to be damaged.

When the storage space for the storage bag 8 is exhausted as the root vegetables are collected, as shown in FIG. 3B, the bag support 22 is lowered from the first mounting posture U to store the selection conveyor 7. The root vegetable recovery is resumed by adjusting to the second mounting posture M in which the length of the bag 8 entering the bag 8 is shorter than that at the start of recovery. Then, the storage bag 8 is moved due to the downward swing of the bag support 21.
The bottom of the bag is lower than that at the start of collection, and a storage space can be formed in the storage bag 8 to such an extent that the drop from the sorting conveyor 7 to the root vegetables C in the bag does not become so large that the root vegetables C supplied from the sorting conveyor 7 fall. The root vegetables can be collected while being dropped into the storage bag 8 in a state in which the root vegetables are less likely to be damaged by the impact.

When the storage space of the storage bag 8 is exhausted due to the collection of the root vegetables, the bag support 21 is further lowered from the second mounting posture M as shown in FIG. All of the conveying end side portion of the sorting conveyor 7 that has entered 8 is adjusted to the lowermost position D that comes out of the storage bag 8 and the root vegetable collection is restarted. Then, due to the downward swinging of the bag support 21, the bottom of the storage bag 8 is further lowered than when the collection is restarted, and the storage bag 8 to the root vegetables C in the bag does not become too large. 8 can form a storage space, and the root vegetable C supplied from the sorting conveyor 7
The root vegetables can be collected while being dropped into the storage bag 8 in a state in which the root vegetables are less likely to be damaged by a drop impact, and can be collected until the storage bag 8 is full.

Even if the bag support 21 is not in the first mounting posture U when the storage bag 8 has a relatively shallow bottom and is empty,
Even if the mounting posture is set between the first mounting posture U and the second mounting posture M or the second mounting posture M, the drop from the sorting conveyor 7 to the bag bottom causes damage due to the drop impact of the root vegetable C. In the case of the storage bag 8 that becomes difficult, as the mounting posture of the bag support 21 when starting the root vegetable collection,
The collection is performed by adopting the mounting posture between the first mounting posture U and the second mounting posture M or the second mounting posture M.

[Other Embodiments] Instead of the cylinder 23,
A screw shaft is attached across the bag support 21 and the support member 22, and when the screw shaft is rotated by an artificial operation, the screw shaft swings and adjusts the bag support 21 by using the support member 22 as a reaction point. An adjusting means is adopted, and a gear mounted so as to rotate integrally with the bag support 21 and a gear meshing with the gear are rotationally operated by an electric motor to swing and adjust the bag support 21. You may implement | achieve using an adjusting means. Therefore, these adjusting means and the cylinder 23 are collectively referred to as the adjusting mechanism 23.
