FIG. 8 is an explanatory view showing a state in which straw scraps are entangled with the conventional receiving network 70. As shown in the figure, in the threshing catch net, the bifurcated straw scrap Y may be stuck across the two workpiece leakage holes 71 located adjacent to each other in the circumferential direction of the barrel. In this case, when the scrap waste Y hangs down from the partition portion 75 across the partition portion 75 located so as to partition the treatment product leakage hole 71 between the two treatment product leakage holes 71, the straw scrap Y Even if the handle teeth 74 of the rotating handling cylinder come into contact with each other, they may be entangled with the receiving net 70 because they are not easily detached from the partition portion 75 just by swinging around the partition portion 75.
In particular, in the case of a threshing receiving net provided with a punched hole for sheet metal or a mesh of a crimp net as a processed material leakage hole, the thickness of the section located between the processed material leakage holes becomes small. The situation where the waste scraps straddling the section is difficult to come off and remains entangled is likely to occur.

  The objective of this invention is providing the receiving net for threshing which is easy to avoid the entanglement of the above-mentioned processed material.

  The first aspect of the present invention includes a receiving net body having a processed material leakage hole, protrudes from between the processed material leakage holes arranged in a circumferential direction on the back surface of the receiving net body, and a cylinder rotation shaft. It is a threshing receiving net provided with a strip plate attached in an attachment posture along the core direction.

  FIG. 7 is an explanatory view showing a state in which bifurcated straw scraps are stuck in the receiving net 70 according to the embodiment of the present invention. As shown in this figure, according to the configuration of the first invention, the diameter of the partition portion 75 located so as to partition the treatment product leakage holes 71 between the treatment product leakage holes 71 arranged in the circumferential direction of the barrel. Even if the processing object leakage hole 71 is inserted into the processed material leakage hole 71, the belt plate 74 projecting from the space between the processing material leakage holes 71 to the back surface of the receiving net body 72 is used as a straw. One end side Y1 of the waste Y is received and supported, and the waste waste Y can be prevented from hanging down from the partition portion 75 and the strip plate body 74 across the partition portion 75 and the strip plate body 74. It can be easily detached by the contact with the tooth handling 74 of the rotating barrel.

  Therefore, even if the threshing receiving net is obtained at a low cost by configuring the receiving net body with a sheet metal or a crimp net, it is easy to avoid that the hulling waste remains tangled and hinder the threshing process.

  In this 2nd invention, the said receiving net main body is comprised with the steel plate in which the said processed material leakage hole was provided by punching.

According to the structure of this 2nd invention, the receiving net | network main body provided with the required leak hole area and intensity | strength can be obtained only by stamping a steel plate.
The back surface of the receiving net body can be made smooth, and the band plate can be easily attached. In particular, attachment by welding can be facilitated.

  Therefore, the threshing receiving net provided with the leakage hole area and strength necessary for the receiving net body can be obtained at low cost from both the production surface of the receiving net body and the attachment surface of the band plate body.
