Description

[Detailed Description of the Invention] The present invention relates to a device for picking up and storing harvested bean culms after drying them on the ground in a bean 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 culms.
Reaped ivy or picked up bean culms are stored in a storage container 3 from a turning section at the rear end of a conveyor 2. Alternatively, a pulse harvester was proposed in which the transport conveyor 2 is tilted downward from the center to the rear in a folded shape, and 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, and 6 are connected by support frames 7 and 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 are moved downward 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 culm from the end of the belt. Reference numeral 20 denotes a sag-preventing ring for the lower belt at the detour portion, and 21 represents a sag-preventing ring for the lower belt at the folded portion of the conveyor belt 2. Note that when dropping the bean culms onto the field to dry on the ground, the trailer 22 of the container 3 is removed from the hitbox 23.

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 rotation direction by a spring not shown in the figure. The shaft 26 is passed between the left and right connecting plates 24 attached to the pulley shaft 17 by the locking fittings 25. A plurality of Vs are formed on the shaft 26.
A pulley 28 is attached, and a support frame 27 for bearing a front lower V-pulley 29 corresponding to each V-pulley is rotatably attached to a shaft 26 for each pulley group.

A grain picking and conveying belt 30 is placed between each of 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.

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 culms 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

to be transferred to.

The present invention relates to a drying grain culm picking up device in a harvester as exemplified above, in which each support frame 27 supports each V-belt and pick-up and conveyance belt.
By providing the gauge wheel 31 as described above, the sled does not dig into the ground unlike the sled disclosed in Japanese Patent Application Laid-open No. 60-9418, and the sled always rolls on the ground surface, responding to its unevenness. By moving the front end of the picking belt 30 up and down, the ground-dried bean culms can be picked up smoothly.

Furthermore, a circular arc hole 40 centered on the upper support pulley (drive shaft) 26 is provided in each of the support frames 27 below the position of the upper support pulley (drive shaft) 26, and a guide rod 41 passing through each of the circular arc holes 40 is connected to the connecting plate. It is supported by a receiving plate 42 extending from 24.

By providing the hole 40 and the guide rod 41, each support frame 27 and belt 30 can be attached to the gauge wheel 31.
The action of moving up and down according to the unevenness of the ground surface is
Compared to the conventional case where only the pulley shaft 26 is used, there is no tendency to twist and the process is performed smoothly. Further, the arcuate hole 40 restricts the vertical range, which has the effect of eliminating the possibility that one belt may accidentally jump up and drop the bean culms being conveyed.

As shown in FIG. 2, the upper and lower parts of the support frame 27 are bifurcated 27a, 27b, and
It is desirable to position pulleys 28 and 29 between a, 27b and 27b. 43 is a bean culm guide rod provided along each belt 30.
