CONSTITUTION:When grains are fed from a grain feeding hopper 19 by starting an electric motor 14 and a motor 36, the grains are made to flow forcedly from a feed port 12 into a bucket elevator 1 due to the following grains and by means of the conveying scraping boards 31... of a flow conveyor 26. The grains are lifted and conveyed by means of buckets 7... and discharged out of a grain discharge port 9 to be fed to the following process via a discharge gutter 18. Since the feed port 12 of the bucket elevator 1 is provided in a posi tion lower than a lower shaft 4, the top face part 20 of a grain feed hopper 19 can be placed on a low position on a floor surface, to facilitate the feeding of grains in bag bodies piled on the floor surface into the grain feeding hopper 19 by a man's hand.

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 at a low position. It is desirable that there be.

Therefore, as shown in FIG. 11, a packet elevator 102 is installed in the pit 101, which bends the floor 100 to form the bit 101 and transports the grain to the next stage, and the upper surface 103 is connected to the floor 100. Supply hopper 10 on the same level
The supply device 1 connects the discharge portion 105 of No. 4 to the supply port 107 provided on the back surface 106 of the packet elevator 102.
08 has been implemented, but this one has a supply hover part
104 allows the grains to flow out of the bag, which has the advantage of omitting the manual labor of lifting the bag. However, on the other hand, it is not suitable for inspecting the rotary shaft at the bottom of the packet elevator 102 or cleaning the inside of the bit 101. , it is necessary to remove the lid member 109 suspended horizontally on the bit 101, and it is difficult to work inside the bit 101.If the capacity of the supply hopper 104 is increased, the bit 101 must be made deeper; The cost of applying water intrusion prevention measures to the wall surface of the machine or bending the bit 101 was made high.

Furthermore, as shown in FIG. 12, there is a known example in which a screw conveyor 112 is provided at the inner bottom of the supply hopper 110 in order to increase the grain supply capacity of the supply hopper 110 and to reduce the depth of the bit 111. However, in this case as well, cleaning or maintenance and inspection work inside the bit 111 is inconvenient, as in the above-mentioned known example.

As a known example in which a stake hopper and an elevator are provided on the floor, for example, JP-A No. 59-20732.9
The tensioning auxiliary device disclosed in the publication includes a screw conveyor installed horizontally in a tensioning hopper formed integrally with a loading platform, and a grain discharging port provided on the outer peripheral side of the grain feeding trough of the screw conveyor. The grain threshing port and the lower supply port of the elevator are connected via a connecting cylinder, and the powder loaded on the truck is moved to the receiving platform of the loading hopper, and the grain is transferred from the opened bag to the loading hopper. The grains are fed into the elevator, transported horizontally by a screw conveyor, and supplied to the elevator via the screw conveyor's grain outlet and connecting cylinder, where they are fried and transported to the next process. In this case, the height of the loading platform of the tensioning hopper is determined by the position of the lower supply port of the elevator, and in order to manually tension the bags that are heavily loaded on the floor, I had to lift it up to the stakeout stand,
This left room for improvement.

[Problem that the invention seeks to solve]

In any of the above-mentioned known techniques, it is difficult to configure the bit shallowly or to form the loading position of the loading hopper provided on the floor at a low position. As shown in FIG. 11, if the grain supply port 107 is not opened at a position above the tangent to the outer orbit A of the rotating packet, the grains will not reach the packet elevator. No inflow.

Therefore, in the present invention, grains are supplied from a position lower than the position where the lower shaft of the packet elevator is mounted, and the grain supply port is set at a lower position.
A grain conveyor placed inside the bottom of the grain supply hopper connected to the packet elevator forces the grains to flow into the supply port of the packet elevator, eliminating the need for a bit and allowing the grains to be fed from as low a position as possible. It is an object of the present invention to provide a device capable of feeding grain to a grain feeding hopper.

Means for Solving the Problems) In order to achieve the above 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, and A packet belt with a large number of packets attached 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. A grain conveying body is rotatably housed in the bottom of a grain supply hopper, which has an opening in the side wall at a lower position to serve as a supply port, an opening in the upper surface, and a peripheral wall. The grain discharge section is connected to the supply port as a means for solving the problem.

(Function) The grains supplied to the grain supply hopper are forcibly supplied from the grain discharge section of the grain supply hopper to the supply section of the packet elevator by the grain conveyor, and are lifted by a large number of packets. The fed grains are discharged to the grain discharge port and supplied to the next process.

Since the grain supply body forcibly supplies grains to the supply port of the packet elevator, the supply port can be provided at a low position. The grain supply section can be formed at a low position on the floor surface, making it easy to supply grains from the bag and also facilitate cleaning and maintenance.

When the electric bowl 14 and the motor 36 are started and grains are fed from the grain supply hopper 19, the flow conveyor 26
The grains are transported horizontally to the grain discharge section 39 by the conveying scraper plate 31, and the grains in the grain discharge section 39 are forced by subsequent grains to flow into the packet elevator 1 from the supply port 12. However, the grains lifted by the packets 7 and discharged to the grain discharge port 9 are supplied to the next process via the discharge 118.

Since the supply port 12 of the packet elevator 1 is provided at a lower position than the lower shaft 4, the upper surface 2 of the grain supply hopper 19
0 can be set at a low position on the floor surface, and the bags stacked heavily on the floor surface can be easily fed to the grain supply hopper 19 by hand. Further, maintenance and inspection of the lower shaft 4, the flow conveyor 26, etc. can be performed extremely easily on the floor.
