DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a bean stressor.

[Prior Art] Conventionally, there has been known a Beanstresser provided with an endless sorting belt provided in a rearward rising inclination posture which is higher toward a rear end side below a handling chamber, and a first spiral provided in front of the endless sorting belt. is there. This is to drive the endless sorting belt in a tilt-up direction, and perfect grains (fine grains) that easily roll on the endless sorting belt flow down in the tilt-down direction and are taken into the first spiral, while: The shavings and pod particles that are likely to be locked on the endless selection belt are conveyed in the upward direction of inclination by the driving of the endless selection belt, and are discharged rearward.

For example, in the microfilm of Japanese Utility Model Laid-Open No. 60-62234, a crimp net stretched along the outer periphery of the lower part of the handling cylinder, a downflow guide fixing frame provided in a downwardly inclined posture below the crimp net, An endless sorting belt that is provided in a rearward rising inclination posture that is located at a lower rear position of the fixed frame for the flow-down guide and that is higher toward the rear end side, a first spiral provided in front of the endless sorting belt, and a lower end of the rear end portion of the endless sorting belt. Characterized in that it comprises a culm belt provided in a rearward position with a predetermined interval facing the front end portion and provided in a rearwardly inclined posture that is higher toward the rear end side, and a second receiving box provided below the front end portion of the culm belt. Beanstresser is disclosed.

In addition, in Japanese Utility Model Publication No. 58-44822, a crimp net stretched along the outer periphery of the lower part of the handling cylinder, a conveyer conveyor provided below the crimp net, and a rear end portion of the conveyer conveyor which is located at a lower rear position thereof. The endless sorting belt which is provided in a rearward rising inclined posture that is higher toward the side, the grain trough provided below the front end of the endless sorting belt, and the front end which faces the upper end of the rear end of the endless sorting belt so that the front end faces the rear end. Disclosed is a beanlesser, which comprises an endless recovery third belt which is provided in a rearward rising inclination posture which is higher toward the section side and a sorting conveyor which is provided from the rear end of the crimp net to above the endless recovery third belt. .

The microfilm of Japanese Utility Model Laid-Open No. 54-115375 includes a sieving element stretched below the shedding element, a swinging frame provided swingably below the sieving element, and a position below the swinging frame. Facing down to the rear end portion side, the descending guide plate provided in a rearward rising inclination posture, the first spiral provided in front of the descending guide plate, and a predetermined rearward position below the rear end portion of the descending guide plate. A collection guide plate provided in a rearward rising inclination posture with the front end facing the rear end side, a second spiral provided in front of the recovery guide plate, and a grain elevator that communicates from the end of the second spiral to the handling chamber. A bean stressor is disclosed, which comprises:

[Problems to be Solved by the Invention] In the above-mentioned conventional technique, even whole grains may be mixed in shavings or pods and may be conveyed backward by an endless sorting belt. The recovery efficiency of perfect grains in the most spiral was only low.

For example, in the beanlesser disclosed in the above-mentioned No. 60-62234 microfilm, first, the leaked material from the crimp net and the dust in the handling chamber are made to flow down onto an endless sorting belt, and the endless sorting is performed. The complete particles rolling on the belt are collected by the first spiral. Then, an endless sorting belt conveys the upper part of the rear and gives a wind sorting action to the falling objects to be sorted from the rear end portion, thereby separating the second item such as pod particles and the culm and the like, The second item is collected in the second inbox, and culms and the like are placed on the culvert belt to be discharged backward. That is, the second product directly drops into the second receiving box through the front-rear space between the rear end of the endless selection belt and the front end of the culm belt.

For this reason, if perfect grains are mixed in this second product,
This perfect grain also dropped into the second inbox with the second one,
It becomes difficult to separate and collect the perfect grains from the second product.

Further, in the beanlesser disclosed in Japanese Utility Model Publication No. 58-44822, first, a leaked substance from the crimp net is made to flow down onto an endless sorting belt by a conveyor, and rolled on the endless sorting belt. Collect the whole grain in the mixed grain gutter. On the other hand, through a route different from this, the handling room dust that did not leak to the crimp net is conveyed backward while being sorted by the sorting conveyor, and made to flow onto the endless recovery third belt. Then, the substance leaked during the transportation by the sorting conveyor, and the complete particles rolling on the endless collecting third belt are allowed to flow down on the endless sorting belt, and the perfect particles rolling on the endless sorting belt are flowed. Collect in a grain gutter.

Then, the shavings, pod particles and the like that are locked on the endless recovery third belt and the endless selection belt are discharged from the rear end of each belt. For this reason, when perfect grains are mixed in the shavings, pod particles, etc. that are locked on the endless recovery third belt and the endless sorting belt, the perfect grains are also discharged to the outside and become a loss. .

In addition, in the beanlesser disclosed in the above-mentioned micro film of Japanese Utility Model Publication No. 54-115375, as a result of the swing selection by the rocking body and the wind selection by the Karako, the object to be sorted taken up by the second spiral is lifted. The whole amount is returned to the handling room by a grain machine and the pod-grained grains are completely re-processed. For this reason, even the perfect grains in the objects to be sorted are subjected to the action of the handling cylinder, and as a result, the perfect grains are damaged and the grade as a product is deteriorated.

As described above, in the conventional technology, since the perfect particles are sorted and collected only once by the endless sorting belt for the objects to be sorted, the culms and pod particles discharged from the rear end of the endless sorting belt are collected. It was not possible to recover the complete grains mixed in, resulting in a loss. However, if an object to be sorted discharged from the rear end of the endless sorting belt is returned to the handling chamber and reprocessed, the complete grains contained therein are damaged and the commercial value is reduced. It was a thing.

[Means for Solving the Problems] The present invention takes the following technical means in order to solve the above problems.

That is, the crimp net 17 stretched along the outer periphery of the lower portion of the handling cylinder 14.
A swinging frame 22 that is swingably provided below the crimp net 17, an endless selection belt 29 that is provided in a rearward rising inclined posture that is located at a lower rear position of the swinging frame 22 and is higher toward the rear end 32 side. The endless sorting belt 29 is provided with the most spiral 28 in front of it and the front end 31 facing the lower end of the rear end 32 of the endless sorting belt 29 so that the rear end 33 is higher and the endless end is provided. Collection third belt 30 and the endless collection third belt
30 and a second spiral 34 provided on the front side of the bean threader.

[Effects of the Invention] The technical means of the present invention configured as described above has the following effects.

The grain culm supplied to the handling room is subjected to a shedding action by the handling barrel 14 and becomes a sorted object such as a perfect grain, a podted grain, and a shaving. Then, among the objects to be sorted, the objects to be sorted that have leaked from the crimp net 17 flow down onto the lower swing frame 22 and are transported rearward by the swing of the swing frame 22.

Then, the objects to be sorted flow down from the rear portion of the swing frame 22 onto the endless sorting belt 29 below. At this time, the endless selection belt 29 has a rearwardly inclined posture and is driven so as to be conveyed rearward and upward. Therefore, the endless sorting belt
Of the objects to be sorted that have flowed up to 29, mainly the perfect grains that easily roll down flow down on the endless sorting belt 29 toward the inclined downward side and are taken into the first spiral 28 provided in front of the endless sorting belt 29. Be recovered.

Further, among the objects to be sorted, pod particles, shavings, etc., which are hard to roll on the endless sorting belt 29, are locked on the endless sorting belt 29 and conveyed rearward and upward. Complete grains may also be mixed in the seed grains and shavings.

Then, these objects to be sorted fall from the rear end portion 32 of the endless sorting belt 29 onto the endless recovery third belt 30 with the front end portion 31 facing to the position below the rear end portion 32. At this time, the endless recovery third belt 30 has a rearwardly inclined posture and is driven to be conveyed upward and rearward. Therefore, similar to the above, among the objects to be sorted which have fallen onto the endless recovery third belt 30, the easy-to-roll complete particles flow down on the endless recovery third belt 30 to the inclined downward side to collect the endless recovery. The second spiral 34 provided in front of the third belt 30 is taken in and collected. Also, among the items to be sorted, the endless recovery third belt
Since the pod-like grains and shavings that are hard to roll on 30 fall from the rear end portion 33 of the endless recovery third belt 30 to a position in the vicinity of the outside, they can be collected in a post-stroke container and appropriately reprocessed. .

As described above, complete particles that could not be completely sorted by the endless sorting belt 29 can be reliably collected by sorting again by the endless collection third belt 30, preventing loss of perfect grains and dramatically improving collection efficiency. Is something that can be done. still,
As a result, the sorted matter discharged from the rear end portion 33 of the endless recovery third belt 30 does not contain the perfect particles, so that, for example, as a configuration for returning the sorted matter to the handling chamber and reprocessing it. However, there is no risk of damage to the perfect grain, and there is no fear of reducing the commercial value.

The operation and effect of the present invention have been disclosed in, for example, the above-mentioned microfilm of Japanese Utility Model Publication No. 60-62234, Japanese Utility Model Publication No. 58-44822, and microfilm of Japanese Utility Model Publication No. 54-115375. The drawbacks of the prior art can be eliminated.
