Description

[Detailed Description of the Invention] The present applicant has filed Japanese Patent Application Publication No. 59-146510 (Japanese Patent Application No. 58-146510).
No. 20493), a reaping device and a picking device B are removably installed at the front of a main body A, which is equipped with a conveyor 2 inclined from the lower front to the upper rear of the machine frame 1. The conveyor 2 is configured so that the upper side can be folded backwards from approximately the center to drop the grain rods to the ground, and the grain rods are harvested by combining two machines: harvesting by reaping and harvesting by picking up and harvesting the harvested land after drying. I suggested a machine.

The present invention relates to a pick-up device for ground-dried grain rods that is suitable for application to the above-mentioned harvesting machine. The purpose is to obtain a device that can be transported to the next process without damaging it.

First, an example of a main body A to which the device of the present invention is applied will be explained with reference to FIG. It consists of a machine frame 1, a crawler 3, an engine 4, an operator's seat (not shown), a vertical frame 6 that supports the shaft of a pulley 5 that drives a conveyor 2, and others. The conveyor 2 is an endless conveyor belt made of rubber or synthetic resin, for example, about 1.5 m in length, and grain rod locking protrusions 2a are provided on the surface vertically and horizontally.

Side plates 7a and 7b made of light plastic plates are placed at both ends of the conveyor belt 2 to prevent grain rods from falling out. Upper side plate 7
b and 7b are provided between the drive pulley 5 and the upper turning shaft 9.

10 is a reinforcing frame 11 provided on the lower side plates 7a, 7a.
A hydraulic cylinder installed between the conveyor and the machine frame 1 supports the lower part of the conveyor and adjusts its overall inclination. A hydraulic cylinder 12 is installed between the machine frame 1 and the reinforcing frame 13 provided on the upper side plates 7b, 7b, and is connected to the reinforcing frame 13 with a rod 14 and a lever 15 to support the upper side of the conveyor. is used as a fulcrum to tilt backwards and downwards as shown by the chain line in Figure 1. Reference numeral 16 designates a number of bearing wheels supported by shafts attached to the vertical frame 6 in order to prevent the lower surface from sagging when the upper side of the conveyor belt 2 is tilted backwards and downwards as shown by the chain line in FIG.

A reaping machine is attached to the shaft 8a of the lower turning shaft 8 in place of the pick-up device B shown in FIG. , and is dropped into the storage basket 18 from the position of the upper turning shaft 9 shown by the solid line in FIG. Alternatively, a threshing machine may be used instead of a storage basket to thresh grains.

When the harvested grain rods are to be dried on the ground, the trailer on which the storage baskets are placed is removed, and the upper side of the conveyor belt 2 is pushed backwards and downwards as shown by the chain line using the hydraulic cylinder 12, and the grain rods are dropped onto the ground and dried. The conveyor band drive pulley 5 is driven by a hydraulic motor (not shown) arranged on its axis.

When storing dried food on the ground as described above, the picking device B is attached as shown in Fig. 1, and the storage basket 18 or the threshing machine is arranged. It is.

As shown in Figures 2 and 3, a plurality of V pulleys 21 are attached to the drive shaft 20 passed between the left and right frame plates 19, 19, and the support frame 22 is rotated around the drive shaft 20 toward the front for each V pulley. A lower V-pulley 23 is attached to the front end of each support frame 22 with a shaft 23a, and a V-belt/conveyor belt 25 having grain rod locking protrusions 24 formed on its surface is suspended around the upper and lower pulleys 21, 23 and driven. The shaft 20 is configured to be driven by a hydraulic motor M.

The support frame 22 for each conveyor belt 25 connects two forks 22a and 22b attached to the shafts 20 and 23a with the V pulleys 21 and 23 in between, and the upper and lower forks, and connects the support frame 22 between the upper and lower sides of the conveyor belt 25. An example configured with a positioned connecting rod 22c is shown. 27 is a grain rod guide rod 28 which is provided in parallel along both sides of the upper side of each conveyor belt 25 with its lower end fixed to the connecting rod 22c;
is a sled that protrudes downward and rearward from the connecting rod 22c.

As shown in FIG. 2, the frame plate 19 has a V-shaped notch 29 for receiving the shaft 23a on the back side, a locking rotating plate 30 that closes the notch, and the rotating plate 30 is attached in the locking direction. It is also possible to provide a one-touch connection mechanism consisting of a coil spring 31 that applies force.

Reference numeral 34 in FIG. 1 denotes a well-known right cylindrical side rake supported at the front end of an arm frame 32 projecting forward from the frame plate 19. That is, by changing the angle of the rake tooth 33 using the eccentric mechanisms 34a and 34b, the protrusion 24
It performs an auxiliary action to further push up the grain rods which are scooped up and conveyed upward by the conveyor belt 25.

The grain rod picking device of the present invention distributes several V-belts and conveyor belts 25 equally over the entire width of the next conveyor belt 2, and the grain rods dried on the field surface are picked up by the projections 2.
4 scoops it up and carries it onto the belt 25 onto the conveyor belt 2.
Transport to. Each conveyor belt 25 is independently supported by a rotatable support frame 22 on a drive shaft 20, so the front part can move up and down individually according to the unevenness of the field surface, so that it can be picked up reliably. . Since the conveyor belt 25 is made of rubber synthetic resin, it hits the grain rods softly and does not cause damage. Therefore, beans are less likely to burst. The conveyor belt 2
5 is also used as a V-pulley, which has advantages such as a simple drive mechanism.
