Description

[Detailed description of the invention] The present invention relates to a pulse harvester.

The present applicant has proposed a main body A that includes a conveyor 2 installed on a machine frame 1 so as to be inclined rearwards, and 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 sticks,
Reaped ivy or picked up bean rods are stored in a storage container 3 from the rear end turning part of the conveyor 2. Alternatively, he proposed a beans harvesting machine in which the conveyor 2 is tilted downward from the center to the rear so that the harvested crops are dropped onto the field for drying (Japanese Patent Application Laid-Open No. 1983-1999).

To explain the outline using the example shown in Fig. 1,
E drives the crawler 4 with an engine. A lower side plate 5 and an upper side plate 6 are arranged along both sides of the conveyor belt 2, and the side plates 5, 5, 6, 6 are connected by support frames 7, 8, respectively. 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 a conveyor belt inclination adjusting hydraulic piston cylinder 12. The upper side plate support frame 8 is supported on the machine frame 1 by a hydraulic piston cylinder 13 and a lever 14 for folding the upper belt in the middle. When the piston cylinder 13 is retracted from the state shown in the figure, the belt 2 and the upper side plate 6 move downwards as shown by the chain line. tilt to.

Belt turning pulleys 15, 16 are supported by shafts 17, 18 between the lower ends of the lower side plates 5, 5 and between the upper ends of the upper side plates 6, 6, respectively. Those pulleys 1
One of the shafts 1, 15, and 16, for example 11, is rotated by a hydraulic motor to drive the conveyor belt 2. The upper end of the conveyor belt 2 is detoured downward by a guide pulley 19 to smoothly fall the bean rods from the end of the belt. Reference numeral 20 designates a sag-preventing ring for the lower belt at the detour portion thereof, and 21 represents a sag-preventing ring for the lower belt at the folded portion of the conveyor belt 2. In addition, when dropping the bean sticks onto the field to dry on the ground, they are removed from the hitbox 23 of the trailer 22 of the storage container 3.

In the illustrated example of the pick-up device B, the loop portion of the connecting plate 24 is hooked from above to the lower pulley shaft 17 of the conveyor belt 2, and the connecting plate 24 bears a bearing and is always biased in the counterclockwise direction by a spring not shown in the figure. The shaft 26 is passed between the left and right connecting plates 2 attached to the pulley shaft 17 by the locking fittings 25. A plurality of V-pulleys 28 are attached to the shaft 26, and a support frame 27 for bearing a front lower V-pulley 29 corresponding to each of the V-pulleys is rotatably attached to the shaft 26 for each pulley group.

A grain rod picking up and conveying belt 30 is hung between the upper and lower V pulleys 28 and 29, and its 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.
Install in step 2. Each picking belt 30 individually moves up and down about the shaft 26 to adapt the front lower picking part to the unevenness of the field.

34 is an arm frame 35 protruding from the left and right connecting frames 25
A well-known right cylindrical side rake bearing a
The eccentric mechanism operates the rake teeth 36 to assist in pushing the crops picked up by the belt 30 and carried upwards further.

Note that the conveyor belts 2, 30 are provided with locking protrusions 2a, 30a to prevent the bean rods from slipping off. Also machine frame 1
A worker boarding platform, a seat, a control panel, etc. are provided protruding from the side, but are omitted from the diagram.

Further, the reaping device may be of the same type as a conventional grain reaping machine, and the connecting plate 2 of the picking device B
5 and attach the same connecting plate of the reaping device to the shaft 17. In either case, the bean sticks smoothly move onto the conveyor belt 2.
to be transferred to.

Conventionally, in the above-mentioned pulse harvesting machine, beans are stored in a basket-like container 3, and when a certain amount is reached, they are taken out and piled up in a small pile on the field (called a nio).
It was naturally dry. However, if the objects that fall from the upper end of the conveyor belt 2 into the basket are left to their own devices, the objects will be accumulated in one direction and the amount of objects that can be accommodated will be small. In addition, it took a lot of effort and time to manually scoop out the stored materials and make niobium, resulting in poor efficiency.

The present invention aims to solve this problem. That is, the circumference of the torso is vertically divided into two parts 40a and 40b, which are joined by a hinge 41 so as to be openable and closable, and one part 40a can be fixed integrally with the bottom plate 42, and the niobium molding machine 40 equipped with a stopper 43 is attached to the bottom plate. The center is rotatably attached to the trailer 22 with a shaft 44. The body is made of iron plate or a fine perforated plate or net to prevent the bean rods from flying out. A step 45 on which a worker stands is provided in a part of the trailer 22.

It is possible to form a circular bottom approximately the same size as the bottom 42 of the Nio molding machine, and a vinyl furoshiki 46 is provided with a necessary width around the periphery and several strings 47 are provided around the widened part. prepare.

The bodies 40a and 40b of the niobium molding machine 40 are closed and fastened with the fasteners 43, and the operator steps onto the step 45.
Spread the furoshiki 46 on the bottom of the molding machine 40 and tie the string 4
7 on the upper edges of the cylinders 40a and 40b as shown in Fig. 2 and let it hang outside the cylinders. The forming device 40 is gradually rotated to uniformly deposit the bean rods falling from the conveyor belt 2. When a certain amount has accumulated, the forward drive is temporarily stopped, the openings of the bathing mats 46 are quickly tied together with strings 47, and the body 40b is opened as shown by the chain line in Figure 3 and lowered. Ni-N is formed.

Since the present invention has the above-mentioned configuration, it is possible to form the harvested bean rods quickly, efficiently, and neatly, and is useful for improving the efficiency of this type of harvesting machine.
