[Prior Art]

 When a conventional combine combine with a binding machine conveys threshed straw to the binding machine for binding processing, the higher the working speed of the combine, the more the amount of grain culm supplied to the binding machine by the straw chain. However, since the transport speed of the straw chain is constant, the layer thickness of the grain culms becomes large, and the separation of the grain culm between the binding portion at the binding machine and the portion to be bound next becomes poor and the next binding portion becomes The grain culms are picked up and disorder occurs.

[0003]

[Problems to be solved by the device]

 In consideration of the fact that such a phenomenon occurs in the conventional case when binding the threshed straw, the present invention prevents the phenomenon associated with the conventional high-speed work from occurring and disturbs the grain culm during bundling. It is an invention aimed at providing a combine with a binding machine that can prevent the occurrence of clogging and prevent clogging.

[0004]

[Means for Solving the Problems]

 Therefore, in order to achieve the above object, the present invention detects the amount of grain culm to be supplied in a combine with a binding machine that transports threshed straw by a straw chain and supplies it to the binding machine for processing. The configuration is such that the transport speed of the straw chain is automatically changed according to the detected amount. Along with this, it is preferable that the binding processing speed of the binding machine is automatically changed.

[0005]

[Action]

 As a result, the threshed straw is transported by the straw chain and supplied to the binding machine to be bound into a predetermined size in sequence.In that case, the amount of supplied grain culm is detected and the detected amount is increased or decreased. As a result, the transport speed of the straw chain is adjusted so that the layer thickness of the grain culms supplied is not thickened and is supplied to the binding machine to be bound. Therefore, since the grain culm layer does not become thicker even if the amount of grain culm increases, the grain culm can be smoothly and smoothly bound without being disturbed. In addition, when the bundling speed of the binding machine is changed as a result of the speed change of the transfer speed of straw chains, the transfer speed is increased without increasing the thickness due to the straw chain, and the grains that are supplied are efficiently supplied. Becomes united well.

It is mounted on the left side of the vehicle chassis (2), (7) is the control unit, (8) is the grain tank, and (9) is the engine. These are on the right side of the vehicle chassis (2) from the front side in order. It is arranged.

[0007] (B) is a mowing unit including a weeding board (10), a raising device (11), a cutting blade (12), and a transport mechanism (13) for supplying the mowing grain culm to the threshing unit (A). , (14) is a discharge ogre that lifts up and takes out the grain stored in the grain tank (8) from the rear side of the engine (9), and is located at the rear side of the threshing section (A). The straw cutter (C) and the tying machine (D) are attached to the straw cutter (C) to supply the straw cutter (C) with something to be cut or supplied to the tying machine (D). Whether or not it is tied into a predetermined size is freely switchable according to the desire, and the straw treatment can be selected.

Therefore, the grain culm cut by the cutting unit (B) is supplied to the threshing unit (A) and is threshed by the handling cylinder (5) while being sandwiched and transferred by the feed chain (4), The processed grain is stored in the grain tank (8), and the threshed straw is transferred from the feed chain (4) to the straw chain (1) and conveyed backward. The grain cut in a predetermined length by a cutter (C) or bound by a binding machine (D) and stored in the grain tank (8) is appropriately discharged by an auger (14). It is taken out.

Next, the core part of the present invention will be described with reference to FIG. 1 and FIG. 2. Threshing threshed straw is inherited from the end of the feed chain (4) and conveyed backward. Between the straw chain (1) and the pinch rail (16), a pinch rail (16) with an ammunition (15) interposed is installed below the chain (1). A sensor for detecting the amount of grain culms to be sent after moving up and down depending on the increase or decrease in the amount of grain culms passing through the straw passage, that is, the layer thickness − Is set.

[0010] The power transmission means from the engine (9) to the straw chain (1), the straw cutter (C) and the binding machine (D) will be described below. (17) is an intermediate shaft. A variable-diameter pulley (21) is provided on the intermediate shaft (17) to change the effective transmission diameter by the rotation of the cam (18) and the tension of the belt (20) hung around the engine pulley (19). ) Is mounted, and two intermediate pulleys (22) are mounted on the sides of the variable diameter pulley (21). The belt (24) is wound around one of the two and the drive pulley (23) at the beginning of the straw chain (1) to drive the straw chain (1). A belt (26) is wound around one intermediate pulley (22) and the input pulley (25) of the straw cutter (C), and the belt is attached to the side portion of the input pulley (25). A belt (29) is wound around the input pulley (28) of the binding machine (D) from the power transmission pulley (27) of the binding machine (D) through the straw cutter (C) to the binding machine (D). It is supplying power. In addition, (30), (31) and (32) show the automatic tension pulleys of the belts (24), (26) and (29).

The lower end of the support rod (33) at the rear side of the pinch rail (16) is connected to one end of an actuating arm (35) which swings up and down with an intermediate portion as a fulcrum shaft (34). The tip of the cam arm (36) extending from the above-mentioned cam (18) and coming into contact with the other end is interlockingly connected by the interlocking rod (37), and the amount of grain culm passing through the straw passage is increased. When the layer thickness becomes large, the pinch rail (16) is displaced downward against the ammunition (15), and the displacement causes the actuating arm (35) to swing about the fulcrum shaft (34). The effective diameter of the variable diameter pulley (21) is changed to the small diameter side by the cam (18) which moves and rotates via the interlocking rod (37) and the cam arm (36) to rotate the intermediate shaft (22). I try to increase the speed.

Therefore, when the amount of grain culm supplied to the straw cutter (C) or the binding machine (D) increases, the grain cutting rail (16) detects this and the engine pulley ( 19) Through the variable-diameter pulley (21) driven from (19), the rotation speed of the straw chain (1), the rotation speed of the straw cutter (C), and the input pulley of the binding machine (D).
