BACKGROUND OF THE INVENTION The present invention relates to a cylinder type cutter for cutting and processing feed crops, straw culms, etc., by changing the ratio of the rotation speed of the feed roll to the rotation speed of the main shaft. The present invention relates to an improvement in a device for adjusting a cutting length.

[0002]

2. Description of the Related Art As shown in FIGS. 1 and 2, a cylinder type cutter A normally cuts a material to be cut into a supply gutter 2 provided on a front end side (right end side in the figure) of a machine frame 1. ,
The feeding roll chamber 3 is mounted on the machine frame 1 so as to be connected to the base end of the supply gutter 2, and the feeding rolls 30 and 31, which are vertically mounted opposite to each other, are arranged behind the feeding roll chamber 3. A cutting room 4 mounted on the machine frame 1 so that a receiving port 40 is connected to the end side.
And cut into the cutting chamber by a rotary blade 50 provided to be rotated by the main shaft 5 and a fixed blade 51 provided at a position along the lower edge of the rim of the receiving port 40. The processing object is configured to be discharged out of the machine through a discharge gutter 41 connected to the discharge port opened to the rear side of the cutting chamber 4.

[0003] A main shaft 5 serving as a rotary shaft of the rotary blade 50 is provided.
In the main shaft 5, the input pulley 5a provided at one end of the main shaft 5 is transmitted to a motor shaft such as a motor. The upper and lower feed rolls 30 and 31 are driven by mounting an intermediate shaft 6 parallel to the main shaft 5 on the machine frame 1 and connecting one end of the intermediate shaft 6 to the main shaft 5 with the transmission pulleys 60 and 6.
1 and the conduction belt 62, and the other end of the intermediate shaft 6 is conducted to one shaft end of the rotating shaft 310 of the lower feeding roll 31 via the conduction gears G1 and G2, and the rotation thereof is performed. The other end of the shaft 310 is connected to the transmission sprocket gear G
Counter shaft 7 via 3.G4 and conduction chain 32
To the one end of the rotation shaft 310 of the upper feed roll 30 which is vertically movable around the center of the counter shaft 7.
It does this by conducting through G6.

[0004] The cutting length of the material to be cut is set by the rotation speed of the feed rolls 30 and 31 (the peripheral speed of the feed rolls 30 and 31) with respect to the rotation speed of the main shaft 5 (the rotation speed of the rotary blade 50). Of the transmission gear G1 attached to one end of the intermediate shaft 6 and the rotation shaft 310 of the lower feeding roll 31
A transmission gear G2 attached to one end of the gear is detachably assembled, and another set of compatible transmission gears G7 and G8 having a different number of teeth is suspended and prepared in the machine frame 1 as a spare. In addition, another set of the transmission gears G7 and G provided for the alternate replacement of the transmission gears G1 and G2 and the interchangeability.
8, compatible with the transmission gear G7
The transmission pulley 6061 that conducts between the main shaft 5 and the intermediate shaft 6 is formed as a split pulley whose effective diameter expands and contracts. In addition to the two-stage shift by the transmission pulleys 60 and 61, the transmission is performed by eight stages of 2 × 4 = 8.

[0005]

The adjustment of the cutting dimension by changing the ratio of the rotation speed of the feed rolls 30 and 31 to the rotation speed of the main shaft 5 is usually performed by adjusting the cutting dimension as follows.
Once the adjustment is made, the cutting operation is performed without any change. Therefore, setting the gear ratio to a desired one of the eight gear ratios described above does not cause any particular trouble.

[0006] However, when raising livestock and performing cutting work on straw culm or the like in order to adjust the feed and litter of the livestock, a very short length of about 1 to 2 cm is required for adjusting the feed. 1 for cutting work set to cutting dimensions and litter adjustment
The cutting work set to a relatively long cutting size of about 5 cm must be frequently repeated, and it becomes troublesome to perform a speed change operation for each of these two works.

Further, as described above, the cylinder type cutter A is provided with a speed changing means which uses the conductive pulleys 60 and 61 and the conductive belt 62 for transmitting the electric power between the main shaft 5 and the intermediate portion 6, and a transmission device provided between the intermediate shaft 6 and the lower portion. Rotary shaft 310 of roll 31
And transmission means using transmission gears G1 and G2 for transmission between the transmission gears and the transmission gears G1 and G2. In order to obtain the speed, there is an annoyance that both the speed change operation on one side of the machine frame 1 and the speed change operation on the other side must be performed.

Further, since the transmission pulley 60 provided on the main shaft 5 for conducting between the main shaft 5 and the intermediate shaft 6 is usually provided at a position inside the input pulley 5a as shown in FIG. In order to operate the speed change means using the 60, there is a trouble that the input pulley 5a and the conductive belt 5b wound around the input pulley 5a must be removed.

The present invention has been made in order to solve these problems which have occurred in the conventional means. In order to adjust the cutting dimension of the cylinder type cutter, the speed of the feed rolls 30 and 31 is changed. On one side of the machine frame 1, transmission means using a transmission mechanism such as the conduction pulleys 60 and 61 and the conduction belt 62 between the main shaft 5 and the intermediate shaft 6, and the transmission shaft 31 of the intermediate shaft 6 and the lower feed roll 31. The transmission can be performed in a state in which both transmissions are combined with the transmission means using the transmission gears G1 and G2 between the rotation shaft 310 and the intermediate shaft 6 and the rotation shaft 310 of the lower feeding roll 31. Transmission gear G1, G2
Can be performed without removing any of the transmission pulleys 60 and 61 and the conduction belt 62 between the main shaft 5 and the intermediate shaft 6 without any obstacles. The present invention provides a new means that enables the speed change operation of the speed change means using the transmission mechanism between the intermediate shaft 6 and the transmission mechanism to be performed without being restricted by the transmission mechanism that transmits the main shaft 5 and the output shaft m of the motor M. The purpose is to do.

[0010]

At the outer end on the side where the pulley is mounted, the conductive gear is removably fitted to a portion located outside the conductive pulley, and the conductive gear meshing with the conductive gear is rotated by the lower feed roll. An object of the present invention is to provide an apparatus for adjusting a cutting length of a cylinder type cutter which is detachably fitted to an outer end of a shaft.
