Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a grain feeding device that feeds grains at a low position and conveys the grains to the next process.

(Prior Art) Generally, grains are stored in bags as a means of temporarily storing or transporting grains.

During secondary processing of grains, the bag is opened to supply the grains to the supply section of the secondary processing equipment, but in order to manually supply the grains from the bag to the supply section, the supply section must be placed at a low position. It is desirable that there be.

Therefore, as shown in FIG. 4, the floor surface 46 is bent to form a bit 47, a bucket elevator 48 for conveying the grains to the next stage is installed inside the bit 47, and the four upper surfaces are bent to form a bit 47. A feeding device 54 has been implemented in which the discharge portion 51 of the feeding hopper 50 is flush with the feeding port 53 provided on the rear surface 52 of the bucket elevator 48. Since the grains flow out from the bag, there is an advantage that the lifting force i/I = pear can be omitted; In this case, it is necessary to remove the lid member 55 suspended horizontally over the pit 47, and it is difficult to work inside the bit 47. If the capacity of the supply hopper 50 is increased, the pit 47 must be deepened. Applying water intrusion prevention measures to the wall of the pit 47;
Alternatively, the cost for excavating pit 47 was made high.

In addition, as shown in FIG. 5, in order to increase the grain supply capacity of the supply hopper 56 and to reduce the depth of the pit 57, a screw conveyor V-5 is installed at the inner bottom of the supply hopper 56.
There is also a known example in which a bit 57 is provided, but like the above-mentioned known example, cleaning or maintenance inspection work inside the bit 57 is inconvenient.

A tensioning auxiliary device disclosed in Japanese Patent Application Laid-Open No. 59-207329, for example, is a known example in which a tensioning hopper and an elevator are provided on the floor. A screw conveyor is installed horizontally, a grain discharging port is provided on the outer peripheral side of the grain feeding trough of the screw conveyor, and the grain discharging port and the lower supply port of the elevator are connected via a connecting solid, and the flour loaded on the truck is The grains are first moved to the receiving platform of the tensioning hopper, and the grains are thrown into the tensioning hopper from the opened bag body, transported horizontally by the screw conveyor, and transferred to the elevator via the grain threshing port of the screw conveyor and the connecting cylinder. The grain supplied to the machine is fried and transported to the next process, but in this device, the height of the loading platform of the tensioning popper is determined by the position of the lower supply port of the elevator. In order to manually tension a bag placed on the floor, it is necessary to lift the bag to the tensioning stand, leaving room for improvement to lower the position of the tensioning stand. Met.

(Problems to be Solved by the Invention) In any of the above-mentioned known techniques, it is difficult to make the pit shallow or to form the staked-out hopper provided on the floor at a low position. The question is whether to install the grain supply port of the bucket elevator at a low position, but as shown in FIG.
If 3 is not opened, grains will not flow into the bucket elevator.

Therefore, the present invention supplies grains from a position lower than the position where the lower shaft of the bucket elevator is mounted, and sets the grain supply port at a lower position.
A grain transport body rotatably installed in a grain supply hopper connected to the bucket elevator is configured to force the grains to flow into the supply port of the bucket elevator, eliminating the need for a pit and placing it as low as possible. The technical problem is to provide a device capable of supplying grains from a grain supply hopper to a grain supply hopper.

Means for Solving the Problems] In order to achieve the above-mentioned technical problem, the present invention has an upper shaft and a lower shaft rotatably mounted on the upper and lower parts of an upright cylindrical case, respectively. A bucket belt equipped with a large number of buckets is wound between pulley wheels inserted into the shaft and the lower shaft, respectively, and the lower shaft of the cylindrical case is provided with a grain discharge port at the upper part. An opening is provided on the side wall surface at a low position to serve as a supply port, and a plurality of grain pieces are fixed to a rotating shaft protruding inside the supply hopper formed by surrounding the side wall on the bottom wall panel. In order to solve the problem, a conveyor is used, and a grain discharge section opened in the bottom wall plate and the supply port are integrally connected via a gutter.

[For production]

The grains supplied to the supply hopper are forcibly supplied from the grain discharge part of the supply hopper to the supply port of the bucket elevator by a grain conveyor, and the grains lifted by a large number of buckets are It is discharged to the discharge port and supplied to the next process.

Since grains are forcibly supplied to the supply port of the bucket elevator by the grain conveyor, the supply port can be provided at a low position, and since the supply port is at a low position, the grains are not supplied to the supply hopper. The part can be formed at a low position above the floor surface, making it easy to supply grains from the bag, and also facilitate cleaning, maintenance and inspection.

(Example〕 An embodiment of the present invention will be described based on FIGS. 1 and 2.

Reference numeral 1 indicates the entire elevator, and the bucket elevator 1 has an upper shaft 3 and a lower shaft 4 rotatably mounted above and below the cylindrical case 2 that is installed upright.
