[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pre-processing device for extracting and extracting root vegetables from a field, and a root vegetable storage section of a root vegetable harvesting machine equipped with a conveyor for transporting and dropping the root vegetables from the pre-processing device into a storage bag and dropping them. Regarding the structure.

[0002]

2. Description of the Related Art In the above-mentioned ginseng harvesting machine, a bag hanging device 31 and a bag receiving device 32 are provided below the end of the conveyor 7 as shown in FIG. Even when the harvesting operation is performed by supporting the large storage bag 8 having a deep bottom, the ginseng is broken by the impact of dropping from the conveyor 7 by receiving the bag receiver 32 on the bottom of the storage bag 8 and adjusting the swing. To avoid damage or damage. That is, FIG.
As shown in (a), when the empty storage bag 8 is attached,
By raising the bag holder 32 to a horizontal position and lifting the bottom of the storage bag 8 to a position near the conveyor 7, the ginseng from the conveyor 7 is hardly damaged even if it falls on the ginseng in the bag. The head from the conveyor 7 to the bottom of the storage bag 8 is kept small. Then, when the ginseng in the bag increases and the storage space of the storage bag 8 decreases or disappears, the size of the storage space or the storage bag 8 remaining in the storage bag 8 as shown in FIG. The bottom of the storage bag 8 is adjusted by lowering the bag holder 32 by an appropriate angle according to
The space from which the ginseng enters the storage bag 8 is formed while the head from the conveyor 7 to the ginseng in the bag is not damaged by the drop impact of the ginseng.

[0003]

In the above-mentioned conventional damage avoidance technology, there has been a problem that damage occurs on a surface different from that of falling from the conveyor to the storage bag. That is, when the bag receiver is lowered and adjusted, especially when the lowering angle of the bag receiver becomes a steep angle, as shown by a two-dot chain line in FIG. Due to the inclination of the bag holder 32, the bottom portion of the storage bag 8 slides out of the bag holder 32 and protrudes outward, and the ginseng in the bag is held at the end of the bag holder as the bag slides out of the bag holder. They could be rubbed and damaged. Also, the overall shape of the storage bag when it is full becomes distorted and the amount that can be stored is reduced, or when the bag is removed from the hanging device and placed on the ground etc., it is difficult to stand due to poor stability. Sometimes happened. SUMMARY OF THE INVENTION It is an object of the present invention to provide a root vegetable storage unit that can collect root vegetables such as carrots in a storage bag having a deep bottom so that the root vegetables are hardly damaged and troubles such as deformation of the storage bag do not occur. Is to do.

[0004]

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

[0005] In the root vegetable storage part structure of a root vegetable harvesting machine provided with a pre-processing device for extracting and extracting root vegetables from a field, and a conveyor for transporting and dropping the root vegetables from the pre-processing device to a storage bag and dropping them. A bag support for hanging and supporting the bag is swingably attached to a support member so as to swing up and down while supporting the bag opening of the storage bag,
As the bag support rises and swings from the lowermost position, so that the transport end side of the conveyor enters the inside of the storage bag, and as the rising angle of the bag support from the lowermost position increases. The length of the conveyor into the storage bag is configured to be long, and an adjustment mechanism for adjusting the mounting angle of the bag support is provided.

[Operation] When an empty storage bag is mounted, the adjustment mechanism adjusts the bag support to the mounting position on the ascending side. Then, the conveyor's transport end side goes deep into the bag and the bottom of the storage bag approaches the conveyor, so that 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 the root vegetables can be collected while preventing the root vegetables from the conveyor from falling on the root vegetables in the bag. Then, when the amount of collected root vegetables increases and the storage space of the bag decreases or disappears, the bag support is lowered by the adjusting mechanism so as to lower at 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 lowered at once to the stroke end, and root vegetable collection is resumed. And, when the bottom of the storage bag is deep, first, it is lowered to the mounting position in the middle until the stroke end is reached, and the root vegetable collection is restarted.
If the bag storage space is reduced or exhausted, the bag support is lowered and adjusted again to the stroke end. Collect root vegetables. Then, if the bottom of the storage bag is shallow, even if the bag support is lowered at once to the stroke end, all of the conveyor terminal side part that has been in the storage bag until then will come out of the storage bag. In addition, the shallow bottom of the storage bag creates a space for the root vegetables to enter the storage bag while minimizing the drop from the conveyor to the root vegetable in the bag, and is damaged when the root vegetables from the conveyor fall on the root vegetable in the bag. The root vegetables can be collected until the bag is full, while preventing the occurrence of wrinkles. And, when the bottom of the storage bag is deep, by lowering the bag support several times without lowering it all at once to the stroke end, and adjusting the lowering, when restarting root vegetable collection, Each time, the end of the conveyor that had been in the storage bag until then comes out of the storage bag by the length corresponding to the downward adjustment stroke of the bag support, and stores while reducing the drop from the conveyor to the root vegetable in the bag. The root vegetables will be collected by forming a space for root vegetables in the bag, and finally, the bag support tool will be lowered to the stroke end, so that all of the conveyor terminal side part will come out of the storage bag. Root vegetables will be collected. Thus, even in the case of a storage bag having a deep bottom, root vegetables from the conveyor can be collected until the bag is full, while preventing damage to the root vegetables from falling onto the root vegetables in the bag. The bag support adjusts the head by moving the bottom toward or away from the conveyor while supporting the storage bag so that the bottom side is always hanging down.

[Effect] Since the head can be collected while adjusting the head from the conveyor to the root vegetables in the bag so that damage due to a drop impact is unlikely to occur, and the storage bag always hangs from the bag support, it is conventionally generated. By being able to adjust the head while avoiding possible 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 little or no damage.
In addition, since the storage bag is always in a hanging state, as the root vegetables enter, it becomes the original shape of the bag due to its weight and pressure. This has made it possible to work advantageously, for example, by stably placing the old bag and handling it easily. In addition, the conventional bag holder is raised and lowered while maintaining the horizontal state, so that the storage bag does not easily slide out,
Compared with the modification of the support structure of the bag receiver to the pantograph-type link mechanism, it was possible to obtain an economical advantage by simply modifying the swingable bag support.

5, the pre-processing device 10 is provided with a positioning transfer device 16, a cutting transfer device 17, a pair of left and right drive rotary blades 18, 18, and a foliage transfer device 19. The weeding tool 11 and the raising device 12 are connected to the root vegetable C to be extracted.
And the foliage portion F of the non-pulling target root vegetables C, and the foliage portion F of the drawing target root vegetables C is caused and processed. The soil cutting blade 13 cuts down the soil on both sides of the root vegetables C to be pulled out, so that the root vegetables C can be easily pulled out. The pair of pulling endless rotating belts 15 and 15 hold the foliage portion F of the root vegetable C from the weeding tool 11 and the raising device 12 and hang it obliquely upward and rearward to transport the root vegetable C from the field. Pull it out and transport it upward and backward. As the pulling endless rotating belt 15 suspends and transports the root vegetable C pulled out from the field, the mustard root cutting device 14
Acts on the beard roots extending from the lower end of the to cut off and remove the mustache roots. When the pulling endless rotating belt 15 hangs and transports the root vegetable C further to the rear side of the fuselage, the positioning and conveying device 16 for aligning the root of the root vegetable C to a fixed position is moved between the root of the root vegetable C and the pulling endless rotating belt 15. The pulling endless rotating belt 15 lifts the transported root vegetables C by a difference in the inclination angle between the pulley and the positioning and transporting device 16. Thereby, the positioning transfer device 16
Positions the transported root vegetable C such that its head has a predetermined positional relationship with the rotary blade 18. After that, the root transport C from the pulling endless rotating belt 15 and the positioning transport device 16 is taken over by the transport device 17 for cutting and transported to the rear of the machine body to supply the foliage F to the rotary blade 18. The foliage F of the root vegetable C is cut at the root. When the cutting process is completed, the cutting transport device 17 drops and supplies the root vegetables C to the conveyor 5 and supplies the foliage portion F to the foliage transport device 19. The foliage transport device 19 includes a drivable endless rotating chain 19a and a holding rail 19b. The foliage F from the cutting transport device 17 is gripped, transported to the front of the machine body, and dropped into the field. discharge. As a result, the pretreatment device 10 pulls the root vegetables C from the field, removes the foliage F, and puts them into the rear side of the machine body.

[0010] The root vegetable storage section 20 is configured such that the transporting end side of the sorting conveyor 7 is formed by a pair of left and right bag hanging rods 21a, 21a and a connecting rod 21b connecting the leading ends of the two bag hanging rods 21a, 21a. 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 attached to the column of the sorting conveyor 7 at the base end of both bag hanging rods 21a, 21a. Dual-purpose support member 22
The cylinder 23 is attached to both sides of the bag support 21 so as to swing around the axis X in the lateral direction of the machine body and extends over the bag hanging rod portion 21a and the support member 22. . Then, as shown in FIG.
From the storage bag 8 to be collected.

That is, the attachment string 8a attached to the bag mouth of the storage bag 8 is hooked on a plurality of string hook pins 24 provided on the pair of bag hook rods 21a, 21a. The pair of cylinders 23, 23 is used to adjust the swing to a predetermined mounting posture, and is fixed so that the storage bag 8 and the root vegetable C do not fall even if they are heavy.
The bag support 21 suspends and supports the storage bag 8 at the bag mouth, and enables the root vegetables C to be dropped and supplied from the sorting conveyor 7 to the storage bag 8. When the pair of cylinders 23, 23 is extended and retracted, the two cylinders 23, 23 move the bag support 22 so that the transporting end side of the sorting conveyor 7 enters and exits between the bag hanging rods 21a of the bag support 21. By swinging up and down about the core X, the bag support 21 is raised from the lowermost position D where the mounting position is horizontal or almost horizontal, and the transport end side of the sorting conveyor 7 is placed in the storage bag 8.
And the length of the sorting conveyor 7 entering the storage bag 8 increases as the rising angle of the bag support 21 from the lowermost position D increases.

As shown in FIG. 3A, when the empty storage bag 8 is mounted, the bag support 21 is moved to the cylinder 23.
The swinging operation is carried out, and the transporting 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 long and the root vegetables are collected. Then, the bottom of the storage bag 8 is lifted up near the transport end of the sorting conveyor 7, and the storage bag 8 is empty, and the drop from the sorting conveyor 7 to the bottom of the storage bag 8 is small depending on the depth of the bottom. Even if the root vegetable C supplied from the sorting conveyor 7 falls on the root vegetable C already collected in the storage bag 8, the root vegetable C due to the falling impact is obtained.
Falls into the storage bag 8 in a state where the damage is unlikely to occur.

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

When the storage space for 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 position M as shown in FIG. 8 is adjusted to the lowermost position D where all of the transporting end side portion of the sorting conveyor 7 that has entered the storage bag 8 exits from the storage bag 8, and the root vegetable collection is restarted. Then, due to the swinging movement 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 is not so large that the drop from the sorting conveyor 7 to the root vegetables C in the bag becomes large. 8 can form a storage space, and root vegetables C supplied from the sorting conveyor 7
Root vegetables can be collected while falling into the storage bag 8 in a state where root vegetables are hardly damaged by a drop impact, and can be collected until the storage bag 8 becomes full.

Incidentally, even if the bottom of the storage bag 8 is relatively shallow and the bag support 21 is not in the first mounting position U in an empty state,
Even if the mounting posture is set between the first mounting posture U and the second mounting posture M, or if the second mounting posture M is set, 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 which 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 adopting the second mounting posture M.

[Another Embodiment] Instead of the cylinder 23,
A screw shaft is attached to the bag support 21 and the support member 22. When the screw shaft is rotated by an artificial operation, the screw shaft swings and adjusts the bag support 21 with the support member 22 as a reaction point. An adjusting means is employed, or a gear mounted to rotate integrally with the bag support 21 and a gear meshing with the gear are rotated by an electric motor to adjust the swing of the bag support 21. Adjustment means may be employed. Therefore, these adjusting means and cylinder 23 are collectively referred to as adjusting mechanism 23.
