Description

  The present invention relates to a green soybean harvester.

Generally, there are roughly the following three methods for harvesting green soybeans in the harvest season.
(1) Use a harvesting machine to remove only the green soybean beans from the green soybeans planted in the field.
(2) Pull out the green soybeans in the field with human power or a harvesting machine, transfer them to the workplace or factory, and hang them on a stationary dehuller.
(3) Cut from the roots of green soybeans using a harvesting machine and convey it with a conveyor.

  The green soybeans in the harvesting season are 60 to 70 cm in height, and are about 40 cm above the ground where the cocoon grows, and more than that, the whole is covered with a large number of leaves of 5 to 15 cm. For this reason, for example, in the method of (1) above, when a soybean harvester is torn off with a harvesting machine, a large amount of leaves and branches are mixed together with the green soybean meal. Sorting using fans and human power. It is very difficult to adjust the wind power by sorting with a sorting fan, and if the wind is strengthened to sort a large number of branches and leaves, the soybean pods are discarded together and the yield deteriorates. There was a problem of being housed. In the latter case, after transferring to a factory or the like, the labor of re-sorting by hand was generated twice. On the other hand, sorting using human power has a problem that time is spent for sorting and the freshness of green soybeans after harvesting is reduced. The green soybean harvesting work is an operation from early morning before dawn in order to maintain freshness, and the poor efficiency of the sorting work has been a major obstacle for farmers to expand the green soybean cultivation area.

  Regarding green soybean harvesting machines, there are those disclosed in JP-A-5-103526, JP-A-2000-236725, and JP-A-2000-201519 (Patent Documents 1 to 3). However, in any green soybean harvesting machine disclosed in any publication, the problem that a large amount of leaves and branches are mixed together with the green soybean meal at the time of stripping is unavoidable, and various problems such as low harvest rate and difficulty in sorting work are required. The problem remained unresolved.

  Therefore, the present applicant has previously proposed a green soybean harvester that can remove green leaves before removing green soybean meal from green soybeans cultivated in the field (Patent Document 4).

  The green soybean cake 2 in the storage container 50 is transferred to a transport vehicle (not shown) immediately below by opening the bottom plate 50a from the upper discharge position, and is carried to the shipping factory.

  Next, a method for harvesting green soybeans 1 planted in a field using the green soybean harvester 100 having the above configuration will be described.

  First, the green soybean harvester 100 is positioned so as to straddle the straw, and the engine 11 is started by an operation on the control box 17, and the tearing device 20, the transport conveyor 30 and the sorting device 40 are operated together. The driving force of the engine 11 is transmitted from the operating state to the left and right crawlers 12 to run at low speed.

  While the green soybean harvesting machine 100 is running, the scraper brush 21 located at the head rotates, while the green soybean 1 on the straw is scraped backward, and the guide roller 22 that rotates the scraped green soybean 1 is a rear peeling drum. 23, the rotating tearing claw 23b strips the green soybeans 2 from the green soybeans 1. The green soybean meal 2 that has been stripped and mixed with the foliage 3 is fed toward the rear conveyor 30 in the feed space 28 in the stripping cover 25.

  While the green soybean harvesting machine 100 is running, the demolition drum 23 is moved up and down with the support shaft 29a of the support member 29 as a turning point following the height of the ground G of the straw. That is, if the height of the ground G of the straw is high or low while the green soybean harvesting machine 100 is running, the height adjustment roller 24 moves up and down following the ground, and the peeling drum 23 integrated with the height adjustment roller 24 is also interlocked. Then go up and down. As a result, during traveling of the green soybean harvester 100, even if the height of the straw ground G is high or low, the height at which the straw is peeled from the ground G is always kept constant. As a result, while the green soybean harvesting machine 100 is traveling, the green soybean beans 2 can always be scraped off from the green beans 1 on the basket even if there is ups and downs on the ground G.

  Further, since the front end portion of the transport conveyor 30 is connected to the front end portion of the support member 29 via the bearing 29b and the connecting shaft 29c, the front end portion of the transport conveyor 30 is also lifted in conjunction with the elevation of the height adjustment roller 24. To do. Accordingly, even if the peeling drum 23 moves up and down following the height of the ground surface G of the fence, the front end portion of the transport conveyor 30 moves up and down in conjunction with each other, so that the gap between the stripping drum 23 and the front end portion of the transport conveyor 30 is The clearance is stable, the falling height of the green soybean cake 2 discharged from the demolition drum 23 is stable, and the green soybean cake 2 dropped on the front end portion of the conveyor 30 rolls forward and reliably falls from the front end. It is conveyed toward the rear.

  The green soybean koji 2 and the branches and leaves 3 conveyed rearward on the conveyor belt 34 of the conveyor 30 are evenly and transported by the rotating claws 41c of the leveling device 41 disposed near the rear end of the conveyor 30. It drops onto the screw conveyor 42 from the rear end of the conveyor 30, is brought close to the central portion opened by the rotating left and right screw blades 42 b and 42 c, and is dropped onto the sieve conveyor 43 from the central portion.

  Of the green soybean beans 2 and branches 3 that fall on the sieve conveyor 43 from the rear end of the conveyor 30, most of the lightweight branches 3 are discharged from the suction port 52 a in the upper cover 52 by driving the wind selection fan 44. It is sucked into 45 and discharged from the discharge port 45a to the ground G of the field. The green soybean cake 2 that has fallen on the sieve conveyor 43 falls into the container 50 through the gap between the rod bars 43d and 43d. Part of the remaining branches 3 that have fallen on the sieve conveyor 43 is sucked by the wind-selection fan 44 and discharged from the discharge port 45a of the discharge cover 45 to the ground G of the field. The branches and leaves 3 caught on 43d are conveyed rearward on the sieve conveyor 43 and discharged to the ground G of the field. Thereby, the green soybean cake 2 and the green leaf 3 are selected, and the heavy green soybean cake 2 is completely stored in the storage container 50.

  When the inside of the storage container 50 is filled with the sorted edamame bowl 2, the storage container 50 is lifted to the upper discharge position H, and the bottom plate 50a of the storage container 50 is opened with respect to the transporting vehicle that is laid on or attached to the field. Then move the green soybean 2 inside and move on to the next harvesting operation. The transporter with the green soybean cake 2 placed in a storage bag or the like moves to a shipping factory or the like, and the harvested green soybean cake 2 is shipped while it is fresh.

  According to the green soybean harvester 100, the following effects are obtained.

(1) When traveling, the front end of the conveyor 30 moves up and down in conjunction with the tearing drum 23 that moves up and down following the height of the ground surface G of the basket, so that the green soybean cake 2 discharged from the tearing drum 23 is transported to the conveyor 30. Can be surely received. As a result, it is possible to reduce the overshoot of the green soybean cake 2, reduce the harvest loss of the green soybean cake 2, and improve the harvest efficiency.

(2) Since the rear end portion of the transport conveyor 30 can be slid by the guide portion 35 following the lifting operation of the front end of the transport conveyor 30, the lifting operation of the front end of the transport conveyor 30 is made smooth. be able to. Therefore, during the traveling, the lifting and lowering operation of the tearing drum 23 that follows the height of the ground surface G of the fence can be made smooth, and the tearing work by the tearing drum 23 is thereby stabilized.

(3) Since the engine 11 is arranged above the conveyor 30, the influence of exhaust heat from the engine 11 on the fresh green soybean meal 2 that is conveyed on the conveyor 30 can be reduced as much as possible. Further, it is possible to prevent the dust from the ground from entering the engine 11 during traveling and improve the durability of the engine 11. Furthermore, since the engine 11 is mounted at the approximate center of gravity of the entire harvesting machine, the running stability is improved, and the operation of removing the green soybeans 1 on the straw is stabilized. These actions also reduce the overshoot of the green soybean meal 2.

(4) The branching leaf 3 falling from the rear end of the transport conveyor 30 and the branching leaf 3 dropped on the sieve conveyor 43 can be efficiently sucked by the wind selection fan 44, and the green soybean cake 2 and the branching leaf 3 can be sorted efficiently. . Further, the branch leaves 3 that have not been sucked by the wind selection fan 44 can be reliably selected from the green soybean meal 2 by the sieve conveyor 43. Therefore, the branches and leaves 3 falling into the storage conveyor 50 are eliminated as much as possible.

(5) By using the edamame harvester 100, the edamame pod 2 can be efficiently harvested in a short time even in a field with a large cultivation scale. In addition, the sorting operation of the green soybean meal 2 and the green leaves 3 can be performed with high accuracy simultaneously with the harvest. As a result, the sorting work in the subsequent process is greatly reduced, and the labor of the harvester can be greatly reduced and labor can be saved. In addition, edamame 2 can be shipped while it is fresh.

(6) By using the edamame harvesting machine 100, the stalks of the edamame bowl 2 were reduced as much as possible, the yield of the edamame bowl 2 was increased, and the yield was greatly improved.

  The green soybean harvester according to the present invention is not limited to the structure of the green soybean harvester 100 described in the above embodiment. A dust removing device may optionally be provided in front of the demolition device 20.
