Description

Crop Conveyors for Combines

The present invention relates to a crop transport device for combines, in particular, in the combine harvester for harvesting crops, such as soybeans, while preventing the loss of crops in transit while simplifying the structure of the transport means for transporting the harvested crops to the threshing machine side, The present invention relates to a crop transport apparatus for combines whose structure is improved to enable adjustment of the height.

In general, the soybean crop is about 50 ~ 70cm in height, soybean fruit (hereinafter referred to as soybean) is surrounded by soybean pods, soybeans are separated from the soybean pods by the external physical stimulus It has features.

If excessive friction or impact is applied during the separation of the beans and the pods, the beans are divided into two pieces, causing damage grains, and the bean stems and the pods are excessively crushed and are not discharged outwards, and move together with the beans to the sorting unit. This creates a screening load that does not result in full screening, which contributes to increased foreign matter incorporation into the final harvest.

Therefore, at present, after harvesting by using a bean mowing machine, the bean is harvested by using a bean threshing machine equipped with a tractor or an electric motor equipped with a bean threshing machine through a drying process in a package.

Since the soybean harvesting work is a high-frequency operation, the development of a device capable of harvesting, harvesting, transporting, threshing, sorting-selecting, and collecting and discharging soybeans is required in large-scale soybean farmers.

Some farms use a conventional combine harvester that is conventionally used for barley harvesting soybean harvesting.

However, in the case of soybean harvesting using a conventional ordinary combine, horizontally laid soybean crops are transported into the threshing machine after harvesting, but in this case, soybean crops harvested by external vibration or impact fall to the floor. It may be lost.

In addition, since the harvesting process of the conventional crop is preceded by a mowing operation to cut the bottom of the crop, the angle of the transfer means is fixed in the process of the transfer operation in the form of collecting the crops lying on the floor, If the height is not constant, there is a problem that can not collect the harvested crops.

The present invention was created in view of the above-mentioned problems, and the object of the present invention is that the structure is improved to combine the simple structure while preventing the loss of the crop during the transfer operation of the crop harvested in the harvesting process of the crop To provide a crop transport device for.

Another object of the present invention is to provide a combine crop transfer device for the combine improved structure so that the harvesting of the harvested crops can be easily made by adjusting the height of the transport means even if the height of the bottom of the harvested crops is not constant There is.

The present invention for achieving the above object is provided on the front of the combine body is provided with a combine crop transport apparatus having a transport means for transporting the crop harvested by the harvesting means to the threshing machine side,

220 and 230 for maintaining the tension of the chain member 210 between the drive gear 410 and the drive shaft 150.

Reference numeral 500 denotes a pair of wheels 500 disposed below the frame 100.

More preferably, it is further provided with a height adjusting means for adjusting the height of the frame 100.

The height adjusting means is supported by the support bracket 720 on the frame 100 and the actuator 700, the rod 710 is stretched and operated by an external power source, and interlocked with the rod 710 end of the actuator 700. Rotating shaft 250 that is coupled to the interlocking bracket 750, the interlocking bracket 750 and the key coupled to the fixed bracket 250 connected to the frame 100 connected to the interlocking rotation as the interlocking bracket 750 is rotated And a link bracket 510 coupled to the rotation shaft 250 and rotatably supported by the wheel.

The actuator 700 may employ a hydraulic cylinder in which the rod 710 is stretched as the hydraulic pressure is supplied / discharged from the outside (the combine body).

For this reason, the frame 100 and the transfer chain 300 have a structure in which the height position is variable according to the stretching operation of the rod 710 of the actuator 700.

Referring to the operation of the present invention having such a configuration as follows.

5 is a use state diagram schematically showing a process of transporting the harvested crops using the combine device of the present invention, Figures 7 and 8 is a use state diagram of the height adjustment means.

In the crop cropping device for a combine according to the present invention, after mounting the frame 100 on the front part of the combine body, the angle of the tip of the frame 100 and the transfer chain 300 is adjusted by using the height adjusting means.

The height adjusting means has a structure in which the frame 100 moves upward when the rod 710 of the actuator 700 is extended, and the frame 100 moves downward when the rod 710 is contracted.

Usually, the rod 710 of the actuator 700 is extended, and in this case, the frame 100 is positioned above the wheel 500 (see FIG. 7).

On the other hand, for the collection of harvested crops, by rotating the interlocking bracket 750 in the clockwise direction by contracting the rod 710, the rotating shaft 250, which is coupled to the interlocking bracket 750 and the key is interlocked rotation The link bracket 510 connected to the wheel by the rotation of the rotation shaft 250 is rotated in the same direction as the rotation direction of the interlocking bracket 750.

The frame 100 connected via the rotation shaft 250 and the fixing bracket 250 is lowered by the rotation operation of the link bracket 510 (see FIG. 8).

At this time, the height adjusting means can adjust the height of the frame 100 to a suitable height according to the height of the bottom surface of the rice field or field in which the harvested crops are laid.

Subsequently, when the driving force is transmitted to the driving shaft 150 through the power take-off device of the combine body 10 as described above, the rotational driving force of the driving shaft 150 to the interlocking shaft 200 via the chain member 210. The driving gear 410 coupled to the interlock shaft 200 is rotated.

Subsequently, as the driving gear 410 rotates, the driven gear 420 and the transfer chain 300 interlock to orbit each other in the advancing direction of the clock hand.

When the transport chain 300 is rotated, the transport protrusion 310 is lifted up and placed on the transport chain 300, the crop is mowed on the floor, the crop is placed on the transport chain 300 is the transport chain 300 After being moved on the first guide member 610 by the rotation of, it is moved to the combine body 10 side in a state seated on the second guide member 620 (see Fig. 5).

In this case, the transfer chains 300 arranged in a plurality of rows on the front of the combine body 10 may collect crops harvested in a plurality of rows, and the length of the transfer chain 300 disposed in the center may be different as described above. Since it is disposed longer than the transport chain 300, the crops are collected from the center, and the crops not collected by the transport chain 300 are transported to the left and right sides of the transport chain 300 based on the center. And it is collected by the transfer projection 310 is transported to the threshing machine (not shown) side in the combine body (10).

The crops transferred into the threshing machine are subjected to a series of harvesting operations for threshing, sorting-selecting and collecting discharge as known.

The threshing, sorting-choice, and collection discharge may be carried out through each device is mounted in the existing combine body 10, or through a separate device different from the combine body 10, which is the same as the conventional method Omit.

Therefore, the present invention can be carried out in a simple configuration in the process of harvesting the crop harvested by the above-described embodiment, and can also prevent the loss of the crop during transport using the first and second guide members. In addition, the height of the frame 100 can be adjusted to suit the height of the floor in the process of collecting the crops lying on the floor has the advantage that the convenience of use is increased.
