Description

[Detailed Description of the Invention] The present invention relates to a positioning device for a handling barrel top plate in a threshing machine.

The gap between the top plate of the handling barrel installed above the handling chamber of a top-handling type threshing machine and the tip of the handling teeth installed on the outer periphery of the handling drum is as important for the threshing action as the gap between the receiving net and the tip of the handling teeth. If the gap is widened, the required horsepower and trunk splitting ratio will be reduced, but there will be a disadvantage that the amount of ears to be cut will increase, more ear debris will adhere to the receiving net, and fewer awns will fall off, and vice versa. If the gap is too narrow, a phenomenon contrary to the above will occur. As described above, the gap between the top plate of the handling cylinder and the tip of the handling tooth greatly affects not only the grain shedding action but also the dust removal action, so it is necessary to set the gap accurately in advance to the required dimensions.

Conventionally, to control the dimension of the gap between the tip of the handling tooth and the top plate of the handling barrel, for example, during assembly, a rod-shaped gauge is inserted into the gap between the two from the grain culm supply port side of the threshing machine, and the top plate is fixed at an appropriate height using the gauge. It was done in the same way. However, with this method, it is difficult to accurately mount the top plate of the handling cylinder to the control dimensions in one go because the space between the handling cylinder and the top plate is narrow, and the top plate has a guide plate, etc. Together with this, it was very difficult to manage the dimensions, especially in relation to the teeth at the back, which had the drawback of requiring a lot of time.

The present invention was developed based on the above-mentioned circumstances, and the top plate of the handling barrel installed above the handling chamber of the threshing machine is provided so that its vertical position can be changed and fixed, while a gauge attached to the top plate having a protrusion of a predetermined length is installed. When the top plate is attached to the top plate of the handling cylinder, the protrusion protrudes into the handling chamber, and the projection is normally installed so that it is retracted outside the handling chamber. By configuring the structure so that the gap between the tip of the handling tooth and the inner surface of the top plate is the required appropriate gap when it comes into contact with the tip of the handling tooth, when installing the top plate of the handling barrel, each bar-shaped gauge is attached to the entrance of the handling chamber, unlike conventional methods. This eliminates the need for the troublesome operation of adjusting the gap between the tip of the handling tooth and the inner surface of the top plate while inserting it into the limited narrow space between the handling barrel and the top plate. It is an object of the present invention to provide a positioning device for a handling drum top plate in a threshing machine, which can accurately set the gap and easily manage the size of the gap between the tip of the handling teeth and the handling drum top plate.

To explain the structure of the present invention with reference to an embodiment shown in the drawings, FIG.

They are provided at positions corresponding to the positions of several (for example, 2 to 3) of the handling teeth 2'a of the handling teeth 2' arranged in a straight line in the axial direction.

On the other hand, reference numeral 16 denotes a top plate-mounted gauge, and as shown in FIG. 1
6a, and a protrusion 16c protruding from either the upper surface plate 16'a or the lower surface plate 16''a, and this top plate mounted gauge 16 is easy to handle as shown in FIGS. 3 and 4. Protrusion 16 against body top plate 4
c can be mounted either downward or upward, and when the protrusion 16c is directed downward, the protrusion 16c is inserted into the hole 15 provided in the handling barrel top plate 4.
When the protrusion 16c is turned upward by vertically inverting the gauge body 16a, the gauge body 16a closes the hole 15 (as shown in FIG. 3). (state shown in Figure 4). Then, attach the gauge 16 to the protrusion 16c.
is attached to the handling barrel top plate 4 in a state of protruding into the handling chamber 5 as shown in FIG. 3, and the protrusions 16c, 16c, . By adjusting the vertical height of the top plate 4, the protrusion length of the protrusion 16c is set in advance to a predetermined length so that the gap l between the tip of the handling tooth and the inner surface of the top plate 4 becomes an appropriate gap. Reference numeral 17 denotes a bracket fixed to the top plate 4 of the handling cylinder, and by placing the mounting plate 16b on the bracket 17 and tightening the bolt 19 to the nut 18 fixed to the bracket 17, the top plate mounting gauge 16 is attached to the top plate. It is attached to the plate 4.

Reference numeral 20 denotes an upper cover of the threshing machine A. One end of the upper cover 20 is hinged to the upper end of the side plate 1b, and the other end is attached to the top plate mounting frame 11 via a fastener 21.
It is detachably fixed to the connecting fitting 11b of.
In the figure, 21 is the plate 16 of the top plate mounting gauge 16.
The bolt insertion hole 22 provided at b is a drive pulley for the handling cylinder 2.

In the above-mentioned embodiment, a case has been described in which the protrusion 16c is integrally provided on the gauge body 16a, but the protrusion 16c may be attached to the gauge body 16a so as to be retractable or retractable.

In the configuration as described above, when assembling the threshing machine A, in order to assemble the handling barrel top plate 4, first the top plate mounting gauge 16 is attached to the protrusion 1 as shown in FIGS. 2 and 3.
6c into the handling chamber 5 through the hole 15 of the top plate 4, and after fixing the bolt 19 to the top plate 4, the fastening tool 1
4 is loosened and the top plate 4 is temporarily attached to the maximum height along the elongated hole 12', and then the top plate mounting frame 11 is fixed to the body side with the fasteners 8a. Then, rotate the handling cylinder 2 by hand so that the handling teeth 2'a, 2'a, 2'a are positioned directly above the handling cylinder axis 2a, and then turn the top plate 4 as shown in FIGS. 2 and 3. As shown in FIG.
If the top plate 4 is fixed to the mounting frame 11 by lowering it to the position where it touches the tip of the handle 2'a and tightening the fastener 14 at that position, the gap l between the tip of the handling tooth and the handling barrel top plate 4 will be the appropriate gap. definitely set. Next, after loosening the bolts 19 and removing the top plate mounting gauge 16 from the top plate 4, the gauge 16 is turned upside down as shown in FIG. 16c is evacuated from inside the handling room 5, and a hole 15 provided in the top plate 4.
will be closed by the gauge body 16a. Finally, by fixing the upper cover 20 to the connecting fittings 11b with the fasteners 21, the handling barrel top plate 4
This completes the assembly.

Therefore, when assembling the top plate, the vertical movement of the top plate 4 is adjusted by manually inserting a bar-shaped gauge from the grain supply port 6 into the narrow space between the handling cylinder 2 and the top plate 4, as in the conventional method. There is no need to do this at all, and by simply bringing the protrusion 16c into contact with the tip of the handling tooth 2'c, the appropriate gap between the tip of the handling tooth and the handling cylinder top plate 4 can be set at once over substantially the entire width along the handling cylinder axis 2a. Therefore, the installation work of the top plate 4 can be performed extremely easily and always accurately without causing dimensional errors during installation, and the protrusion 16c can be retracted from the inside of the handling chamber 5 after the top plate is installed. Therefore, the protrusion 16c does not interfere with the threshing action and the dust removal action, and the hole 15 provided in the top plate 4 does not interfere with the gage main body 16a.
Since the hole 15 is blocked by the hole 15, grains and dust will not be scattered outside the handling chamber 5 during the threshing operation.

As mentioned above, the present invention provides a top plate of the thresher that is installed above the handling chamber of the threshing machine so that its vertical position can be changed and fixed, and a gauge attached to the top plate with a protrusion of a predetermined length is attached to the top plate of the handling drum. When installed, the protrusion protrudes into the handling chamber, and normally the protrusion is installed so that it retreats outside the handling chamber, and when the protrusion of the gauge mentioned above is made to protrude into the handling chamber, when the protrusion comes into contact with the tip of the handling tooth of the handling barrel. Since the gap between the tip of the handling tooth and the inner surface of the top plate is configured to be the required appropriate gap, when installing the top plate of the handling cylinder, use a rod-shaped gauge one by one from the entrance of the handling chamber to the space between the handling cylinder and the top plate. The troublesome operation of positioning the mounting height of the top plate while adjusting the gap between the tip of the handling tooth and the inner surface of the top plate by inserting it into a limited narrow space can be completely eliminated, and the protrusion can be inserted into a limited space. The handling cylinder top plate can be attached by simply touching the top plate of the handling cylinder while maintaining the gap between the above two exactly according to the specified control dimension, and it is possible to prevent threshing due to dimensional errors etc. when installing the top plate. This has the effect of reliably preventing adverse effects on the dust removal function and the dust removal function.
