Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a threshing device for a self-removing combine, in which independent protruding teeth are dispersedly arranged on a freely rotatable driving drum.

[0002]

[Prior art]

 Conventionally, in the self-eliminating combine harvester, in order to collect the clams to the grain culms that are held and conveyed by the feed chain, a separating rotary body that acts on the straw that is held and conveyed after the threshing process is provided separately from the handling cylinder. It was configured to collect and collect the clams from the straw along with the handling of the straw.

[0003]

[Problems to be solved by the device]

 However, if a separating rotary member is added in addition to the handling cylinder, the device becomes complicated and expensive, and there is room for further improvement in terms of cost reduction and downsizing of the device. An object of the present invention is to improve the means for collecting clams to be effective for cost reduction and compaction of the device.

[0004]

[Means for Solving the Problems]

 The characteristic configuration of the first invention is that in a threshing device of a self-removing combine, in which independent projecting handle teeth are dispersedly arranged on a handle barrel that can be driven and rotated, a rear side portion of the handle barrel in the grain-carrying and carrying direction. , A separating blade for separating threshed culms is attached, and the separating blade is formed so that the circumferential length of the handle cylinder is longer than the handle teeth, and the rearward direction in the rotation direction is closer to the grain carrying direction. It is formed in a slanted position.

[0005]

[Action]

 In other words, the length of the handle cylinder in the circumferential direction is longer than that of the handle teeth, and the slinging blades that are inclined toward the rear side in the rotation direction are positioned in the grain-carrying and conveying direction with respect to the threshing grain culms that are held and conveyed. If the plunging action is repeated with the rotation of the handling cylinder, a sufficiently large gap will be formed evenly between the threshed grain culms that are carried in a dense and parallel state, and clams on the threshed grain culm will be formed. It falls from the gap and is sent to the sorting section below, so that the recovery of clams can be fully realized. In particular, since the separating blades are attached to the handling cylinder, compared to the case where a separating rotating body is provided separately from the handling cylinder as in the above-described conventional technique, the means for collecting the clams is inexpensive and compact. Can be formed. Moreover, since the slanting blades are inclined toward the rear of the rotation direction in the grain-carrying and carrying direction, and the threshing grain culms are sent in the carrying direction by the sorting blades, the threshing grain culms are handled. However, without giving much resistance to the transfer of threshing culms, it is possible to sufficiently suppress the disturbance of the posture of the threshing culms and to prevent the subsequent handling of straw such as transportation, shredding and binding.

[0006]

[Means for Solving the Problems]

 The characteristic configuration of the second invention is a self-removing combine threshing device in which independent projecting handle teeth are dispersedly arranged on a handle barrel that can be driven and rotated, and a rear side portion of the handle barrel in the grain-carrying and carrying direction. , A separating blade for separating threshed culms is attached, and the separating blade is formed so that the circumferential length of the handle cylinder is longer than the handle teeth, and the rearward direction in the rotation direction is closer to the grain carrying direction. This is because the handling cylinder is provided with an auxiliary separation blade that is formed in a slanted position and that is connected to the separation blade at the tip in the rotation direction and that is lined up on the front side in the grain-carrying and carrying direction.

[0007]

[Action]

 That is to say, the same separating blade as in the first aspect of the present invention, and the auxiliary separating blade that is connected to the separating blade at the tip in the rotation direction and that is arranged on the front side in the grain-plucking and conveying direction, are threshed and transported. However, since the plunging action is repeatedly performed with the rotation of the handling cylinder, a sufficiently large gap is provided between the threshing grain culms in a dense parallel state that are held and conveyed, and the wedges by the cooperative action of the separating blade and the auxiliary separating blade. With the effect, it can be formed evenly and surely, and it is possible to collect enough clam rice for threshing culms. In particular, since the separating blade and the auxiliary separating blade are attached to the handling cylinder, compared to the above-described conventional technique, in which a separating rotary member is provided separately from the handling cylinder, a step for collecting clam rice is provided. It is inexpensive and compact. Moreover, by connecting the auxiliary separating blades to the separating blades at the tip in the direction of rotation and arranging them on the front side in the carrying direction of the threshing grain culling, the threshing grain culms can be removed accurately while the threshing grain culms are properly separated as in the first invention. The culm's posture disturbance can be suppressed sufficiently, and the subsequent processing of straw is not adversely affected.

[0008]

[Effect of device]

 As a result, it becomes possible to satisfactorily collect clams without adversely affecting the transportation of grain culms, and in particular, to provide a more excellent self-removing combine threshing device that can be formed inexpensively and compactly. It was

A feeding chain 9 is provided, and a bag filling hopper 11 for collecting the first grain (grain) that has been threshed and sorted by the threshing device 7 is arranged on the side of the threshing device 7, and boarding operation is performed in front of the hopper 11. The parts 12 are arranged to form a self-removing combine.

The threshing unit of the threshing device 7 is configured as shown in FIGS. 2 and 3. That is, the handling cylinder 14 is provided in the handling chamber 13 so as to be driven and rotatable about the horizontal axis in the longitudinal direction of the machine body, and the independent projection-shaped handling teeth 15 are dispersed and arranged in the handling cylinder 14 almost entirely. In the rear part of the culm-carrying and conveying direction X, four separating blades 16 for separating the threshed culms are provided in a row in the circumferential direction of the handling cylinder 14 and intermittently arranged. The separating blades 16 are formed such that the circumferential length of the handling cylinder 14 is longer than that of the handling teeth 15, that is, a length corresponding to a rotation angle of the handling cylinder 14 close to 90 degrees, and the rearward side in the rotation direction Y. The threshing culm is slanted so as to be positioned in the slinging and carrying direction X, and the slinging blades 16 are repeatedly rushed into the threshing and culm to be held and transported as the handling cylinder 14 rotates. A sufficiently large gap is formed evenly between the threshed grain culms that are held and conveyed in a dense and parallel state by the action of the separating blades 16, and the clams to the threshed grain culm are dropped from the gap to the receiving net 17. Then, the clams can be collected. The height of the separating blade 16 is set so that the tip in the rotation direction Y is low, and the height is higher toward the rear in the rotation direction Y, so that the highest part is almost at the same height as the handle teeth 15. The rushing of the separating blade 16 is performed smoothly.

[Second Embodiment] The following auxiliary separating blade 18 is added to the handling cylinder 14 of the same self-draining combine as in the first embodiment. As shown in FIG. 4 and FIG. 5, the auxiliary separating blade 18 attached to the handling cylinder 14 is connected to the separating blade 16 at the tip in the rotation direction Y, and the front side in the grain-growing and carrying direction X. And the auxiliary blades 18 arranged side by side in a V-shape and extending in the same angular range in the rotational direction Y of the handling cylinder 14 in parallel with each other. The threshing culms to be conveyed are repeatedly rushed with the rotation of the handling cylinder 14, and a sufficiently large gap is provided between the threshing culms in a densely arranged parallel state to be sandwiched and conveyed and the assisting blade 16 and the auxiliary. Formed evenly by the wedge effect by the cooperative action of the blades 18 for separating, as in the case of Example 1, the clams to the threshed rice culm can be dropped and collected on the net 17, and the threshed rice culm can be separated. However, the posture disturbance of the threshing culm is sufficiently suppressed, and it is used for the subsequent treatment of straw. Effects are so as not to occur.

[Other Embodiment] The separating blade 16 can be appropriately selected in terms of length, height, inclination angle, number of installations, arrangement, and the like. The auxiliary separating vane 18 of the second invention can be appropriately selected according to the separating vane 16 in terms of length, height, angle with respect to the separating vane 16, and the like.
