Description

[Detailed description of the invention] This invention is a threshing machine that is installed in a combine harvester, a harvester, etc., or is used stationary.
Specifically, the processing chamber in which the second material to be supplied is transferred along the rotational axis direction of the processing cylinder by the rotation of the processing cylinder and is processed is arranged such that the starting end wall in the transfer direction faces this in the rotational axis direction. A threshing machine is provided to form a gap having an appropriate width and communicating with the sorting chamber at its lower end, and a transmission section for the processing cylinder is provided in the gap. Regarding machines.

In this type of threshing machine, the transmission part for the processing cylinder is provided between the wall of the threshing machine and the wall of the sorting chamber, thereby preventing the transmission part from protruding locally from the wall of the threshing machine. This has the advantage that the entire threshing machine can be made into a compact state with a flat outer surface of the threshing machine wall. If the structure is such that the material to be processed is discharged into the lower sorting chamber only from the bottom, the processing teeth are generally designed to come into sliding contact with the starting end wall in the transfer direction of the processing chamber due to manufacturing accuracy and assembly accuracy of the processing cylinder. Since it is very difficult or impossible to rotate the processing cylinder, the second material fed to the lower part of the processing chamber near the starting wall in the transport direction remains without being subjected to the feeding action of the processing cylinder; Therefore, there is a drawback that cleaning work is required to remove the remaining grains after the threshing work.

The purpose of the present invention is to overcome these conventional drawbacks.

The characteristic configuration of the threshing machine according to the present invention, which was taken to achieve the above object, is that a second feed material located at the starting end of the processing chamber in the transfer direction is placed in the lower part of the starting end wall of the processing chamber in the transfer direction. The advantages of the present invention having such a characteristic configuration are as follows.

In other words, since the second object in the processing chamber can be flowed out from the starting end in the transfer direction through the opening, no second object remains at the starting end in the transfer direction in the processing chamber, and therefore, the second object remaining in the processing chamber after Cleaning work can be simplified or made unnecessary. Moreover,
Instead of forming the above-mentioned opening in the lower receiving net, a gap communicating with the sorting chamber is formed on the outside of the starting end wall in the transfer direction of the processing chamber, and the second material is discharged into the gap, thereby Focusing on the point that the second material can be fed into the sorting chamber and processed, the opening is formed in the lower part of the starting end wall in the transfer direction, and the opening is formed in the lower receiving net. Unlike in the case where the area of the lower receiving net becomes narrower, the processing effect such as grain removal due to the cooperation between the processing cylinder and the lower receiving net can be maintained satisfactorily.

Hereinafter, embodiments of the present invention will be described based on the drawings.

a handling chamber 1 in which grain culms are clamped and conveyed in a sideways posture through a feed chain 2 and a clamping rail 3 by rotation of a handling cylinder 1A;
By rotating the processing cylinder 4A around an axis b parallel to the rotation axis a of the processing cylinder 1A in the lateral side of the handling chamber 1, the second material to be supplied is rotated along the rotation axis direction of the processing cylinder 4A. There is a processing chamber 4 in which the grains are removed while being transferred to the same side as the clamping conveyance, and below both chambers 1 and 4, the fallen materials from both chambers 1 and 4 are moved to the same side as the clamping conveyance. A sorting chamber 5 is provided for transporting to the destination, and at the bottom of the sorting chamber 5, a first article collecting section 6 with a carry-out screw and a second article collecting section 7 with a carry-out screw are provided. The second object carried out from the second object collection section 7 is scattered and supplied into the processing chamber 4 toward the upper side in the transfer direction from the opening 4a formed at the upper part of the end wall 4D of the processing chamber 4 in the transfer direction. a thrower device 8; a winnow 9 for supplying a sorting airflow into the sorting chamber 5;
A threshing machine is constructed by providing a dust removal cross-flow fan 10.

The starting end wall 1B in the transfer direction of the handling chamber 1 is configured to also have a part of the threshing machine wall A facing the starting end wall 4B in the transferring direction of the processing chamber 4 in the axial direction,
Between the threshing machine wall A and the starting end wall 4B of the processing chamber 4 in the transfer direction, there is formed a gap B having an appropriate width and communicating with the sorting chamber 5 at the lower end. A transmission section 11 for the processing cylinder 4A is attached to the wall A of the threshing machine. The transmission section 11 is arranged in a case 12 and has a processing cylinder shaft 16 connected to an input shaft 15 which is driven in the same direction as the processing cylinder shaft 14 via a transmission belt 13.
A pair of gears 17 and 17' are provided for decelerating and rotating the motor in the opposite direction. Further, the end walls 1D and 4D of the handling chamber 1 and the processing chamber 4 in the transfer direction are constructed of a single plate.

The lower walls of each of the handling chamber 1 and the processing chamber 4 are composed of receiving nets 1C and 4C through which the grains can leak, and a receiving net 1 is provided at the transfer end portions of both the chambers 1 and 4.
Openings 1b and 4b are formed for dropping the second item that has not leaked C and 4C.

A swinging sorting device is provided in the sorting chamber 5, and this is a swinging sorting device that is swingably supported via a front and back swinging link 18 and a rear up and down swinging link 19. The frame 20 includes a grain pan 21 that swings and feeds the leaked material from the receiving nets 1C and 4C, a grain sieve 22 that swings and feeds the grains from this and leaks them to the first material collection section 6, and A grain pan 23 that swings and feeds falling objects from both ports 1b and 4b of the chamber 1 and processing chamber 2, a first stroke rack 24 that swings and sorts the objects to be processed, and a dust exhaust port for moving the objects to be processed in the future. A second stroke rack 26 for oscillating feeding and sorting is attached toward 25, and a crankshaft 27 for oscillating the vertical swinging link 18 at the front portion is provided. The first stroke racks 24 are rack plates closer to the processing cylinder 4A, and are positioned at an appropriate number, taking into account uneven distribution of the processed materials in the lateral direction due to the rotation of the processing cylinder 1A and the processing cylinder 4A. By arranging the rack plates 24a in a steeply inclined position with the transfer end located higher than the other rack plates 24b, the material to be processed on the racks is prevented from being blown away by the sorting airflow to the dust exhaust port 25. It is configured as follows.

In addition, the input pulley 28 attached to the crankshaft 27 has a swing frame that moves reversibly forward when the swing frame 20 swings rearward as the input pulley 28 rotates.
