Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a harvester for beans, especially for harvesting beans.
Alternatively, the present invention relates to a bean harvesting machine that picks up bean culms that have been dried on the ground in a field, conveys them upward by a conveyor, and drops them from the upper end into a container for storage.

[Conventional technology]

Among the harvesters described above, one in which a falling guide belt is provided downward from the top of the conveyor is known (see, for example, Japanese Utility Model Application Publication No. 53-20346).

[The problem that the idea aims to solve]

The above-mentioned known guide belt has a structure in which a separate guide belt is provided downward from a lower position with a step relative to the upper turning position of the conveyor, and is driven by a chain linkage from the turning pulley shaft.

Unlike lumpy or granular crops such as onions and corn, stalked crops such as bean culms have their stems, bean pods, leaves, etc. intertwined with each other and remain attached to the non-slip protrusions on the conveyor. , those that tend to go around to the bottom of the conveyor along with the upper end turning drum will cause trouble in the step between the conveyor and the guide belt in the above step configuration,
There is a problem in that it stagnates and does not transfer smoothly to the guide belt.

The object of the present invention is to provide a pulse harvester that solves these problems.

[Means to solve the problem]

In order to achieve the above-mentioned purpose, the present invention has been developed in a pulse harvesting machine that drops harvested products from the upper end of a conveyor 2 that slopes upward to the rear and stores them in a container 3 on a trailer 22. The upper part of the side plate 6 is expanded rearward and downward to form a bearing part 6a, and the upper turning pulley 16 of the conveyor 2 is supported on the upper part of the bearing part 6a.
Also, a conveyor sagging prevention roller 20 is supported by a bearing portion 6a almost directly below the upper turning pulley 16, and the conveyor 2 is moved rearward and downward from the upper turning pulley 16 toward the top opening of the container 3, and then moved to the detouring pulley 19.
This is a pulse harvesting machine in which a detour conveyor part 2b is formed so as to turn from the pulley 19 and go around the sag prevention roller 20 to form a lower descending path of the rear ascending inclined conveyor 2.

[Effect]

With the above configuration, the bean culm that has reached the upper turning pulley 16 is turned and conveyed backward and downward by the same conveyor 2 by the detour conveyor section 2b, and even if there is the above-mentioned entanglement, the bean culm reaches the upper turning pulley 16, and even if there is the above-mentioned entanglement, the bean culm reaches the upper turning pulley 16 and is then turned downward by the same conveyor 2. It falls and is stored in the container 3 while being loose.
Also, even if the conveyor's anti-slip protrusion 2a goes around from the detour pulley 19, the anti-sag roller 2
It is blocked by 0 and falls.

Main body A includes a conveyor 2 installed on the machine frame 1 so as to be inclined upward from the rear, a reaping device (not shown in the figure) that is detachably attached to the front of the main body, and a device B for picking up dried bean culms. The harvested ivy or picked up bean culms are stored in a container 3 from the upper end turning section of the conveyor 2. Alternatively, the storage container trailer 22 is attached to the machine frame 1 using the hitbox 23.
Then, the conveyor 2 is tilted from approximately the center to a bent state with the upper half falling backwards as shown by the chain line, and the harvested crops are dropped onto the field for drying on the ground.

E is an engine, 4 is a crawler, 5 and 6 are lower and upper side plates arranged along both sides of the conveyor 2, and the left and right side plates 5, 5, 6, and 6 are connected by support frames 7 and 8, respectively. be done. A horizontal shaft 9 is passed through the overlapping position of the upper and lower side plates 7 and 8 and supported by a bearing frame 10. A pulley 11 is provided integrally with the shaft 9.
The lower side plate support frame 7 is supported by the machine frame 1 via an inclination adjusting hydraulic piston cylinder 12 of the conveyor 2 . The upper side plate support frame 8 is supported by the machine frame 1 by a hydraulic piston cylinder 13 and a lever 14, and the piston cylinder 13 is retracted from the illustrated state to tilt the upper part of the conveyor 2 together with the side plate 6 backward and downward as shown by the chain line.

Conveyor turning pulleys 15, 16 are provided between the lower ends of the lower side plates 5, 5 and between the upper ends of the upper side plates 6, 6, respectively.
are supported by shafts 17 and 18. Then, the conveyor 2 is driven by rotating the shaft 9 of the intermediate pulley 11 with a hydraulic motor. Reference numeral 21 denotes a sagging prevention roller at the folded portion of the conveyor 2. Note that the conveyor 2 includes not only the wide single belt structure illustrated in FIG. 2, but also the structure of several belts 2.

The pick-up device B is hooked from above on the lower pulley shaft 17 of the conveyor 2 by the proximal groove portion of the left and right connecting plate 24, and is always biased in the counterclockwise direction by a spring not shown in the figure, which is bearing on the connecting plate 24. Locking metal fitting 25
Accordingly, the shaft 26 is attached to the pulley shaft 17 and passed between the other ends of the left and right connecting plates 24. A plurality of V pulleys 28 are attached to the shaft 26, and a support frame 27 that bears a front lower V pulley 29 corresponding to each of the V pulleys is attached to the shaft 26 for each pulley group so as to be able to swing vertically.

A grain picking and conveying belt 30 is placed between the upper and lower V pulleys 28 and 29, and the shaft 26 is driven by a hydraulic motor to rotate all the belts 30. A gauge ring 31 is attached to each support frame 27 of the bearing ring 3.
