Conventional soybean threshing machine has the advantage of automatically threshing the beans from the bean pods and then automatically placing the threshed beans in the bag by the soybean automatic conveyer.

However, in the conventional bean automatic threshing machine having such a configuration, the beans contained in the bucket fall freely downward by vibrating in the process of transferring the beans contained in the bucket upwards, in which the beans are caught between the driven pulley and the conveying belt. This will cause a fatal problem that will break down the quality of the threshing soybeans.

In addition, since the transfer belt and the bucket is easily damaged due to repeated use, when the transfer belt and the bucket are to be replaced, the inconvenience of using the parts must be disassembled.

The present invention has been made to solve such a conventional problem, to improve the structure to automatically discharge the threshed beans by the wind in accordance with the drive of the blower without using a separate bucket to be put on the sack The purpose is.

Another object of the present invention is to allow the foreign substances contained in the beans to be removed by spreading the outside of the stalk while the threshing beans are discharged through the outlet by the wind.

According to an aspect of the present invention for achieving the above object, in the bean threshing machine for automatically threshing harvested soybeans, soybean transport pipe having a rectangular cross section on the bean discharge plate to be installed through each other of the bean transport pipe Connect the blow induction pipe having a venturi tube at one end and the discharge pipe having a bean outlet at the other end of the bean transfer pipe, and connect the discharge port of the blower that is rotated according to the driving of the motor installed at the main body at one end of the blow induction pipe. Provided is a soybean blower conveying apparatus of soybean thresher.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 5 to 8 as an embodiment.

5 is a perspective view showing a bean threshing machine provided with the present invention, Figure 6 is a longitudinal sectional view showing the main part of the present invention, Figures 8a and 8b is a perspective view showing the bean outlet side, the present invention is installed in the main body 61 At the end of the bean discharge plate 62 in which the threshed beans are discharged by their own weight, the bean transfer pipe 63 having a rectangular cross section and having an upward curved portion 63a is installed to pass through each other. In the bean conveying tube 63 positioned on the discharge side of 62, a bean backflow prevention plate 64 bent downward is formed as shown in FIG. 6, and on one side of the bean backflow prevention plate 64, a bean backflow prevention plate The bean guide plate 65 is formed so that it may be located above 64.

This is due to the vortex phenomenon caused by the pressure difference in the process in which the bean 66 threshed through the bean discharge plate 62 is dropped by its own weight and transferred to the discharge observation by the wind generated by the driving of the blower. This is to prevent the beans from flowing back to the bean discharge plate 62 side.

In addition, as shown in FIG. 7, a door 67 for removing foreign matter is provided on the bottom of the bean transfer pipe 63 so as to be openable and openable.

This is because when foreign substances such as stones generated during bean threshing are not discharged by the blowing wind, they stay on the upward curved portion 63a, so that when the pods are caught on the stone, the threshing beans are not discharged by them in the process of being discharged. Therefore, the operator is to open the foreign matter removal door 67 to quickly remove the foreign matter.

A blowing guide tube 68 having a venturi tube 68a is connected to an inlet side (left side) of the bean transfer tube 63 and an upward curved portion 63a formed at an outlet side which is the other end of the bean transfer tube 63. ) Is connected to a discharge pipe 69 having a bean discharge port 69a.

The reason why the venturi tube 68a is formed at the inlet side of the bean transfer pipe 63 is that the wind is generated in accordance with the operation of the blower so that the cross section is reduced in the process of blowing air to the bean transfer pipe 63. This is to make the flow rate faster by.

8A and 8B, the hinge pipe 70 is fixed to the side wall of the main body 61 at the end of the discharge pipe 69, and the hinge pipe 70 has a plurality of claw hook protrusions 71a formed thereon. Form hanger 71 is fitted to rotate around the hinge pipe (70) and to the side wall of the discharge pipe 69, the clamping member 72 is fitted with a catch (71b) fixed to the hanger (71) Is installed.

In addition, when the bean threshing is not performed on the side wall of the main body 61, as shown in FIG. 8B, the stool holder supporting member 73 which hangs the stool holder 71 is fixed, and the discharge portion that is the end of the discharge pipe 69 is fixed. A plurality of through holes 74 are formed on the wall surface, and the windshield 75 is fixed to one side of the stand hanger 71.

The reason why the through hole 74 is formed at the end of the discharge pipe 69 is that the discharge speed of the beans discharged through the discharge pipe 69 is too fast so that the discharge speed of the beans is not soaked and not splashed to the outside. The reason for fixing the windshield 75 on one side of the stand hanger 71 is to prevent the phenomenon of flying soybean pods that are sorted with the wind during the bean threshing operation.

At this time, the door (not shown) for adjusting the discharge speed of the bean 50 is discharged by adjusting the number of open through the outside of the through hole 74 may be slidably installed.

On the other hand, one end of the blow induction pipe 68 is connected to the discharge port 77a of the blower 77 which rotates according to the driving of the motor 76 installed in the main body 61, the blower 77 is a separate Although it may be rotated according to the driving of the motor, another blower (not shown) is driven to discharge the bean pods to the outside in the process of freely falling the threshed beans to the bean discharge plate 62 with the bean pods, etc. More preferably, it is configured to be driven simultaneously by the shaft 78.

Referring to the operation of the present invention configured as described above is as follows.

First, when the bean threshing operation is to be performed in the same state as in FIG. 8B, the stem hanger 71 is separated from the stem hanger support member 73 formed on the side wall of the main body 61 to rotate 90 ° to maintain a horizontal state. Next, when the stopper 71 is horizontally moved so that the stopper 71b formed on the stopper 71 is fitted to the stopper fitting member 72 formed on the discharge pipe 69, the stopper 71b is clamped as shown in FIG. 8A. Since the hook 72 is fitted to the member 72 to maintain the horizontal state, accordingly the hook (not shown) to hang the hook on the hook hook projection (71a) formed in the corner portion of the hook hanger 71 It becomes possible.

As described above, when a stool is placed on the sack hanger 71 and power is applied to the bean thresher, the threshing is made like a normal bean thresher so that the threshing bean 50 falls freely downward so that the bean threshing plate 62 is It is discharged to the bean feed pipe (63).

In the process in which the threshing bean 50 is discharged through the bean discharge plate 62, the blower 77 is driven by the motor 76 to generate wind, and the generated wind is blown induction pipe 68. In the process to be transported along the venturi tube (68a) while passing through the flow rate is reduced by reducing the cross-sectional area soybean (50) discharged through the bean discharge plate 62 through the bean transfer pipe (63) by the wind It is discharged to the discharge pipe 69.

In the process as described above, the threshing soybean 50 is discharged through the discharge pipe 69, as well as the bean is also discharged to the discharge pipe 69 together with the soybean pod, at this time between the outlet and the sack of the discharge pipe 69 There is a small space portion is formed by the pressure difference small soybean pod spreads in all directions not to be put on the sack, only the bean 50 with a large specific gravity is put on the sack by its own weight.

In the process of the threshing beans are discharged through the discharge pipe 69 by the wind, the through hole 74 is formed at the outlet side of the discharge pipe 69, so that the discharge rate of the beans is lowered, so that the beans are not splashed out and put on the sack. do.

On the other hand, when the bean conveying tube 63 is blocked by stones or pods during the threshing process of the bean, so that the bean is not discharged smoothly, the worker removes the foreign matter door 67 installed in the bean conveying tube 63. As it can be quickly removed to remove the foreign matter will be able to discharge the beans smoothly.

As described above, the present invention has several advantages as compared to the conventional bean thresher.

First, the bean is threshed by the wind generated by the blower without the bean being transported by the bucket which is fixed to the conveying belt at regular intervals, thus preventing the bean from being caught between the conveying belts. Of course, there is no need to replace the parts because the transfer belt and the bucket is not used.

Second, the rod hanger can be pivotally installed at the end of the discharge pipe so that the hanger hangs on the side wall of the main body when the bean hanger is kept horizontal only when threshing the bean. It is prevented beforehand.

Third, the bean transport pipe is automatically formed so that the beans are automatically transported by the wind generated by the blower to facilitate the cleaning and removal of foreign matter (stones, pods, etc.).
