Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a bucket conveyor for lifting and transporting grains and a closed-type Glen tank for dropping and collecting the grains transported by the bucket conveyor. The present invention relates to a grain collection device provided.

[Conventional technology]

Introduction The grain recovery device is equipped in, for example, a combine, and the grains are stored in a bucket and transported by lifting, so the grain is rubbed in the lifting cylinder and is easily scratched by a vertical feed screw conveyor. It is suitable for the collection of beans that are less likely to be damaged by the grains and are particularly susceptible to damage to the skin compared to the conventional ones. However, as shown in FIG. 4, conventionally, it was provided along the outside of the Glen tank (012). Bucket (011a) of bucket conveyor (011)
Are sequentially inverted near the end position of the conveyance and the bucket (01
Grains (E) contained in 1a) are discharged into the Glen tank (012) in a free fall state.

Then, a fir sensor (016) for detecting the pressure of the collected grain is provided above and below in the Glen tank (012), and the amount of the collected grain in the Glen tank (012) is based on the detection result of the fir sensor (016). Is displayed on the outside, and when the top fir sensor (016) senses the pressure of the grain, it is judged that the inside of the Glen tank (012) is full, and this is warned by a sound or light alarm, The operator is configured to stop driving the bucket conveyor (011) based on the alarm.

[Problems to be solved by the device]

Therefore, the grain (E) will drop along the inside of the outer peripheral wall of the Glen tank (012) toward a certain position near the position immediately below the transfer end position of the bucket conveyor (011).
The grains (E) tend to be piled up in a state of being deviated to the inner side of the outer peripheral wall around a certain position, and moreover the grains near the conveyance end position of the bucket conveyor (011) are piled up in the above-mentioned piles. Since it is easy to fill the top of (E) early, there is a drawback that it is difficult to effectively utilize the space in the Glen tank (012) to efficiently collect the space.

Furthermore, when the Glen tank (012) is full, it is warned by a sound or light alarm, but the operator may be enthusiastic about another work or may be unnoticed by the surrounding noise, In this case, the bucket conveyor (011)
The bucket conveyor (01
1) is overloaded, which causes the bucket conveyor (011) to fail.

That is, the grain (E) that is full and overflows enters the movement path of the bucket (011a) and resists the movement of the bucket (011a).

The present invention has been made in view of the above situation, and by devising a grain discharge structure from the bucket conveyor into the grain tank, the grain inside the grain tank can be conveyed while the grain is carried up by the bucket conveyor. The grain can be efficiently collected by effectively utilizing the space of the grain, and even if the bucket conveyor is continuously driven even if the inside of the grain tank is full, the grain is less likely to be overloaded. The purpose is to provide a device.

[Means for solving the problem]

Grain recovery according to the present invention The present invention provides a grain conveyor including a bucket conveyor for lifting and transporting the grain and a closed-type grain tank for dropping and recovering the grain transported by the bucket conveyor. In the apparatus, A. A horizontal feed screw conveyor that receives the grains discharged from the bucket conveyor and horizontally conveys the grains toward the center of the grain tank is provided on the ceiling of the grain tank.

B. A scraping blade is attached to the screw shaft of the horizontal feed screw conveyor for ejecting the grains conveyed by the horizontal feed screw conveyor into the Glen tank.

C. On the side wall portion facing the space outside the Glen tank at the conveying end portion of the conveying cylinder of the horizontal feed screw conveyor,
An opening facing the rotation path of the scraping blade is formed, and a cover plate opened by a pressing force from the inside of the Glen tank is provided so as to cover the opening.

The above-mentioned ABC configuration is provided, and the following operational effects are obtained from this configuration.

[Action]

With the configuration of A above, the grains discharged from the bucket conveyor are conveyed to the center side of the grain tank by the horizontal feed screw conveyor in which the grains are relatively not damaged, and b. The grains conveyed to the center side of the are discharged into the grain tank in a state of being scattered radially around the screw shaft.

c. Further, with the configuration of B, the scraping blade can be easily driven by effectively utilizing the screw shaft without separately providing a driving device for the scraping blade.

d. When the bucket conveyor continues to be driven while the inside of the Glen tank is full, due to the above configuration A, the grains are forced into the Glen tank and the internal pressure of the Glen tank gradually increases. In addition, with the configuration of B, the scraping blade in the state of being filled with the filled grains rotates the surrounding grains and imparts a centrifugal force to the grains, so that the internal pressure and the centrifugal force are applied. With the configuration of C, the grain to which is added is pressed against the lid plate to forcibly open the opening, so that the grain overflows from the opening and the increase in the Glen tank internal pressure is alleviated.

Then, regardless of whether the inside of the Glen tank is full, the grains conveyed through the horizontal feed screw conveyor are discharged from the opening to the outside of the Glen tank.

[Effect of device]

By the action of a and b, the grain can be discharged while being dispersed in the grain tank from the center side of the grain tank in a state where the grain is not easily scratched. While utilizing the above, the grains can be efficiently distributed by spreading the grains all over the inside of the Glen tank, and the grains can be efficiently collected.

Further, due to the action of c, the drive structure of the scraping blade can be simplified.

Further, due to the action of d, even if the bucket conveyor is continuously driven in a state where the inside of the Glen tank is full, there is little possibility that overflowed grains will enter the moving path of the bucket, and Less likely to be overloaded.

〔Example〕

An embodiment of the present invention will be described with respect to a grain collecting device provided in a whole culm input type combine used for harvesting grains such as rice, wheat, soybean and buckwheat.

As shown in FIGS. 1 to 3, the all culm throw-in type combiner has a machine body (2) equipped with a pair of left and right crawler traveling devices (1) and a pre-mowing treatment part (A) and a threshing process part.

On the transport end side of the bucket conveyor (11), the grain (E) discharged when the bucket (11a) is inverted downward is received and directed toward the center of the ceiling of the Glen tank (12). Horizontal feed screw conveyor (1
3) is provided with this lateral feed screw conveyor (13)
A scraping blade (14) that rotates integrally with the screw shaft (13a) is attached to the end of the screw shaft (13a) in the conveying direction.

Then, the grain (E) conveyed by the transverse feed screw conveyor (13) is splashed by the scraping blade (14) and radially scattered from the discharge hole (15a) formed in the conveying cylinder (15). In this state, it is discharged into the Glen tank (12).

The fir sensor (16) for detecting the pressure of the collected grain (E) is provided in the upper and lower sides of the grain tank (12), and the grain in the grain tank (12) is detected based on the detection result of the fir sensor (16). The collected amount is displayed on the control unit (C), and when the uppermost fir sensor (16) senses the pressure of the grain (E), it is judged that the inside of the Glen tank (12) is full, and the sound and light Is issued an alarm.

On the upper plate portion (12a) that covers the grain discharge path (17) from the scraping blades (14) of the Glen tank (12), that is, the end of conveyance in the conveying cylinder (15) of the horizontal feed screw conveyor (13). Upper plate part (12a) which forms the side wall part connected to the part
