Description

[Detailed description of the invention] A conventional pre-processing device for a combine harvester has a guide plate erected above the ear tip conveyor, and guides the tips of the culms that are sandwiched and conveyed between the stock head conveyor and the ear tip conveyor. Because the guide was sliding while leaning against a board, there was a delay in the transfer of the tip of the ear.This phenomenon is particularly noticeable in soft culms such as those that have fallen down, and the guide plate becomes an obstacle, making it difficult for the control section to control the conveyance of the culm. It was difficult to see.

In addition, because the upper surface between the tip conveyor and the control section, where the reaping device and culm conveying device are located, was open, straw debris could accumulate on the transmission device and wrap around the rotating parts, making it more likely to cause malfunctions. Cleaning work to remove them was extremely difficult, and it was dangerous to stretch them out or remove tangles from the transfer shell culm during the work.

This invention prevents the guide plate from coming into contact with the tip of the transfer culm and allows the tip to move in an independent and natural posture, thereby preventing transfer delays and grain shedding due to sliding. The inner part of the steering section as well as the upper part between the steering section and the tip are completely covered and sealed with a series of cover plates and partition walls made by bending them, so that the space between the steering section and the tip conveying case is completely covered and sealed. A pre-treatment device for a combine harvester that can prevent straw waste etc. from accumulating or wrapping around the transmission part and frame body etc. provided, and also prevent dust etc. blown up from the transmission part from being blown onto the control part. The purpose is to provide a transport cover.

The present invention will be explained in more detail with reference to the embodiment shown in the drawings below. Reference numeral 1 is a self-described threshing device mounted on a machine base 3 having a traveling device 2. The front part of the threshing device is tilted up and down centering on the upper part. A reaping frame 4 is pivotally connected to the reaping frame 4.
The front part has a side divider 5' and a central divider 5'.
A pair of left and right culm lifting frames 6, 6, etc. are provided, and a stock conveyor chain 8 is stretched from one side above the cutting blade 7 provided at the lower rear of the frame to the other rear side. A stock feed chain 9 is stretched slightly forward of the terminal end of the stock transport chain 8.

In addition, at the front end facing the terminal end of the stock conveying chain 8, the rear part moves far and near in the direction of the culm of the husk being conveyed with respect to the starting end of the husk culm holding transfer body 10 of the threshing device 1. A sprocket at the starting end of the handling depth adjustment chain 11 with a handle is pivotally supported.

Furthermore, a head tip conveying case 13 is provided extending from the top of the stock conveying chain 8 to the front of the supply port 12 of the threshing device 1, and is inclined with a low front and back height and has a conveying belt having a transfer lug hung thereon. There are guide rods 14 arranged in parallel on the conveying surface side.

Furthermore, on the other side of the reaping conveyance section, there is provided a control section consisting of an operation panel 15, a control seat 16, a group of levers, etc.

Then, the upper surface or upper surface 1 of the ear tip conveying case 13
One side of a plate body 17 consisting of a horizontal flat plate is integrally attached to the side, and the outside of the control section of this plate body 17 extends to the vicinity of the control section and is approximately vertical as shown in FIGS. 4 and 6. The downward direction is bent to completely cover the lower support member, transmission mechanism, etc.

Further, the rear portion of the plate 17 is bent approximately horizontally 17a through an intermediate bent portion as shown in FIG. 5, and is slightly higher than the lower plate 12a of the supply port 12.

In the drawing, 18 and 18 are star wheels for scraping, 19 is a cover that covers the upper part of the shell culm conveyance path, and 20 is a cover for a group of operation levers, and the part where the speed change lever 21 is provided is the second
As shown in the figure, it is low and triangular in shape.

In the above-mentioned device, when each part is driven while moving the machine forward, the erect culms are divided, then raised by the culm lifting frames 6, 6, and then cut by the cutting blades 7, and the bedside part is connected to the plant carrying chain. 8 and stock feeding chain 9 and sent later, and then transferred to the handling depth adjustment chain 11.

Then, the tip portion is latched to the lug of a conveyance band stretched over the tip conveyance case 13 and is transferred diagonally rearward and upward while being held between it and the guide rod 14.

At this time, since the grain culm conveyance surface is inclined inward, the sugar part protruding above the ear tip conveyance case 13 stands up due to its own rigidity, but is bent inward due to the weight of the paddy. If the culm is hard, the tip hardly touches the plate 17, but if it is soft, it is guided by lightly touching the upper surface of the plate 17.

When the end of the conveyance is reached, the culm assumes a substantially horizontal position, and its stock part is transferred to the starting end of the culm holding transfer body 10 of the threshing device 1, and the sugar part is guided onto the horizontal bending part 17a. The grains are then transferred onto the lower plate 12a, inserted into the supply port 12 of the threshing machine, and threshed while being conveyed by the shell culm holding and transporting body 10.

The present invention provides a combine harvester in which a control section is provided on one side of the machine body as described above, and a tip conveyance case is provided extending from the middle part of the front section to the rear upper part of the other side. Cover the space between them with a cover plate, bend the control part side of the cover plate downward to form the vertical partition wall 17b, and bend the rear part of the cover plate towards the supply port of the threshing device. This allows the sugar part to be smoothly guided and fed to the supply port, but there is no guide plate on the tip transport case that would obstruct the transfer of the sugar part, unlike in the conventional case. The culm can be transported in a self-supporting, natural and orderly posture without shedding, and the posture, length, etc. of the culm during transportation can be accurately visually checked and appropriate processing can be carried out quickly.

In addition, all straw debris that accumulates or gets wrapped around the downward transmission mechanism or machine frame between the tip conveyance case and the control section is stopped by the cover plate and will naturally slide down, ensuring smooth operation. In addition, cleaning can be performed extremely safely and easily, and the safety of the operator is ensured because the control section is isolated from various transmission mechanisms by the vertical partition wall.

Furthermore, the straw and dust blown upward or toward the control section by the rotating part of the transmission frame are immediately stopped by the cover plate, allowing operation in a good working environment.Moreover, the rotating part is free from sharp protrusions, etc. Since it is not exposed, various manual operations can be performed safely.
